    Full Text Available Abstract Background Analyses of utilization trends (cost drivers allow us to understand changes in colorectal cancer (CRC costs over time, better predict future costs, identify changes in the use of specific types of care (eg, hospice, and provide inputs for cost-effectiveness models. This retrospective cohort study evaluated healthcare resource use among US Medicare beneficiaries diagnosed with CRC between 1992 and 2002. Methods Cohorts included patients aged 66+ newly diagnosed with adenocarcinoma of the colon (n = 52,371 or rectum (n = 18,619 between 1992 and 2002 and matched patients from the general Medicare population, followed until death or December 31, 2005. Demographic and clinical characteristics were evaluated by cancer subsite. Resource use, including the percentage that used each type of resource, number of hospitalizations, and number of hospital and skilled nursing facility days, was evaluated by stage and subsite. The number of office, outpatient, and inpatient visits per person-year was calculated for each cohort, and was described by year of service, subsite, and treatment phase. Hospice use rates in the last year of life were calculated by year of service, stage, and subsite for CRC patients who died of CRC. Results CRC patients (mean age: 77.3 years; 44.9% male used more resources than controls in every category (P Conclusion Use of hospice care among CRC decedents increased substantially over the study period, while other resource use remained generally steady. Our findings may be useful for understanding CRC cost drivers, tracking trends, and forecasting resource needs for CRC patients in the future.

    Smoking is the leading preventable cause of death among individuals with mental health difficulties (MHD). The aim of the current study was to determine the impact of smoking on the physical health of older adults with MHD in Ireland and to explore the extent to which smoking mediated or moderated associations between MHD and smoking-related diseases. Cross-sectional analysis of a nationally representative sample of 8175 community-dwelling adults aged 50 and over from The Irish Longitudinal Study on Ageing (TILDA) was undertaken. Multivariate adjusted logistic regression models were used to assess the association between MHD, smoking (current/past/never) and smoking-related diseases (respiratory disease, cardiovascular disease, smoking-related cancers). A number of variables were employed to identify individuals with MHD, including prescribed medication, self-reported diagnoses and self-report scales. MHD was associated with current (RRRs ranging from 1.84 [1.50 to 2.26] to 4.31 [2.47 to 7.53]) and former (RRRs ranging from 1.26 [1.05 to 1.52] to 1.99 [1.19 to 3.33]) smoking and also associated with the presence of smoking-related disease (ORs ranging from 1.24 [1.01 to 1.51] to 1.62 [1.00 to 2.62]). Smoking did not mediate and rarely moderated associations between MHD and smoking-related disease. Older adults in Ireland with MHD are more likely to smoke than those without such difficulties. They also experience higher rates of smoking-related disease, although smoking had no mediating and no consistent moderating role in these analyses. Findings underscore the need for attention to the physical health of those with MHD including support in smoking cessation. Copyright © 2017 Elsevier Inc. All rights reserved.

    This report retrospectively analyzed the outcome of 91 patients aged 60 years or older with refractory/relapsed (R/R) classical Hodgkin's lymphoma (cHL) who underwent autologous stem cell transplantation (ASCT) between 1992 and 2013 and were reported to the French Society of Bone Marrow Transplantation and Cell Therapies registry. The median age at transplant was 63 years. The majority of patients exhibited disease chemosensitivity to salvage treatment (57 complete responses, 30 partial responses, 1 progressive disease and 3 unknown). The most frequent conditioning regimen consisted of BCNU, cytarabine, etoposide, melphalan (BEAM) chemotherapy (93%). With a median follow-up of 54 months, 5-year estimates of overall survival (OS) and progression free survival (PFS) for the entire group were 67 and 54%, respectively. Despite the missing data, in univariate analysis, the number of salvage chemotherapy lines (1-2 versus ⩾3) significantly influenced the OS, unlike the other prognostic factors (stage III-IV at relapse, disease status before ASCT and negative positron emission tomography (PET) scan) encountered in younger patients. In spite of its limitations, this retrospective study with a long-term follow-up suggests that ASCT is a valid treatment option for chemosensitive R/R cHL in selected elderly patients, with an acceptable rate of toxicity.

    Providing coaches as part of a weight management program is a common practice to increase participant engagement and weight loss success. Understanding coach and participant interactions and how these interactions impact weight loss success needs to be further explored for coaching best practices. The purpose of this study was to analyze the coach and participant interaction in a 6-month weight loss intervention administered by Retrofit, a personalized weight management and Web-based disease prevention solution. The study specifically examined the association between different methods of coach-participant interaction and weight loss and tried to understand the level of coaching impact on weight loss outcome. A retrospective analysis was performed using 1432 participants enrolled from 2011 to 2016 in the Retrofit weight loss program. Participants were males and females aged 18 years or older with a baseline body mass index of ≥25 kg/m², who also provided at least one weight measurement beyond baseline. First, a detailed analysis of different coach-participant interaction was performed using both intent-to-treat and completer populations. Next, a multiple regression analysis was performed using all measures associated with coach-participant interactions involving expert coaching sessions, live weekly expert-led Web-based classes, and electronic messaging and feedback. Finally, 3 significant predictors (Pcoaching session attendance (Pcoaching sessions, attending 60% of live weekly Web-based classes, and receiving a minimum of 1 food log feedback day per week were associated with clinically significant weight loss. Participant's one-on-one expert coaching session attendance, live weekly expert-led interactive Web-based class attendance, and the number of food log feedback days per week from expert coach were significant predictors of weight loss in a 6-month intervention. ©Stefanie Lynn Painter, Rezwan Ahmed, Robert F Kushner, James O Hill, Richard Lindquist, Scott

    Dietary intake is a modifiable exposure that may have an impact on cognitive outcomes in older age. The long-term aetiology of cognitive decline and dementia, however, suggests that the relevance of dietary intake extends across the lifetime. In the present study, we tested whether retrospective dietary patterns from the life periods of childhood, early adulthood, adulthood and middle age predicted cognitive performance in a cognitively healthy sample of 352 older Australian adults >65 years. Participants completed the Lifetime Diet Questionnaire and a battery of cognitive tests designed to comprehensively assess multiple cognitive domains. In separate regression models, lifetime dietary patterns were the predictors of cognitive factor scores representing ten constructs derived by confirmatory factor analysis of the cognitive test battery. All regression models were progressively adjusted for the potential confounders of current diet, age, sex, years of education, English as native language, smoking history, income level, apoE ɛ4 status, physical activity, other past dietary patterns and health-related variables. In the adjusted models, lifetime dietary patterns predicted cognitive performance in this sample of older adults. In models additionally adjusted for intake from the other life periods and mechanistic health-related variables, dietary patterns from the childhood period alone reached significance. Higher consumption of the 'coffee and high-sugar, high-fat extras' pattern predicted poorer performance on simple/choice reaction time, working memory, retrieval fluency, short-term memory and reasoning. The 'vegetable and non-processed' pattern negatively predicted simple/choice reaction time, and the 'traditional Australian' pattern positively predicted perceptual speed and retrieval fluency. Identifying early-life dietary antecedents of older-age cognitive performance contributes to formulating strategies for delaying or preventing cognitive decline.

    Full Text Available Aims: This study classifies cases of traumatic diaphragmatic hernias (TDH in patients admitted to the Intensive Care Unit (ICU of the Coimbra University Hospitals (HUC from 1990 to 2004. Methods: Retrospective analysis of 34 cases of TDH, studying anatomical location, place and time of diagnosis, complementary tests aiding diagnosis, herniated organs, associated traumatism, morbidity and mortality. Results: Twenty-eight male and six female patients with an average age of 40.5 years ± 20.5, average SAPS score 38.8. Average lenght of stay was 19.1 ± 13.6 days, all suffered from closed traumatism and were put on artificial ventilation. The left-side diaphragm was more frequently affected (94.1% then the right. Diagnosis in 19 cases was made up in the first six hours following the diagnosis of traumatism, in four cases within 12 hours and in the remaining cases between 48 hours and 16 years after traumatism. In 13 patients the diagnosis was established intra-operatively. The stomach was typically one of the herniated organs. The most frequently associated lesions at the thoracic level were pulmonary contusion, haemothorax and pneumothorax, and at the abdominal level, haemoperitoneum and splenic lesion. The rates for complications and mortality were 55.8% and 11.7% respectively. Conclusions: TDH mainly occurs on the left side through closed thoraco-abdominal trauma following road traffic accidents. This group of patients, on average younger than others admitted to ICU, presents a longer average hospitalisation period, but has lower rates of mortality and lower SAPS severity scores. The most commonly herniated organ was the stomach and the most frequently encountered lesions were cranial-encephalic, splenic and pleural traumatisms. Pre-operative diagnosis of diaphragmatic injuries is difficult and a high index of clinical suspicion is needed after thoracoabdominal trauma. This diagnosis should always be considered a possibility in

    Full Text Available Purpose. Hand infections are common, usually resulting from an untreated injury. In this retrospective study, we report on hand infection cases needing surgical drainage in order to assess patient demographics, causation of infection, clinical course, and clinical management.Methods. Medical records of patients presenting with hand infections, excluding post-surgical infections, treated with incision and debridement over a one-year period were reviewed. Patient demographics; past medical history; infection site(s and causation; intervals between onset of infection, hospital admission, surgical intervention and days of hospitalization; gram stains and cultures; choice of antibiotics; complications; and outcomes were reviewed.Results. Most infections were caused by laceration and the most common site of infection was the palm or dorsum of the hand. Mean length of hospitalization was 6 days. Methicillin-resistant Staphylococcus aureus, beta-hemolytic Streptococcus and methicillin-susceptible Staphylococcus aureus were the most commonly cultured microorganisms. Cephalosporins, clindamycin, amoxicillin/clavulanate, penicillin, vancomycin, and trimethoprim/sulfamethoxazole were major antibiotic choices. Amputations and contracture were the primary complications.Conclusions. Surgery along with medical management were key to treatment and most soft tissue infections resolved without further complications. With prompt and appropriate care, most hand infection patients can achieve full resolution of their infection.

    Research with younger adults has shown that retrospective cues can be used to orient top-down attention toward relevant items in working memory. We examined whether older adults could take advantage of these cues to improve memory performance. Younger and older adults were presented with visual arrays of five colored shapes; during maintenance, participants were presented either with an informative cue based on an object feature (here, object shape or color) that would be probed, or with an uninformative, neutral cue. Although older adults were less accurate overall, both age groups benefited from the presentation of an informative, feature-based cue relative to a neutral cue. Surprisingly, we also observed differences in the effectiveness of shape versus color cues and their effects upon post-cue memory load. These results suggest that older adults can use top-down attention to remove irrelevant items from visual working memory, provided that task-relevant features function as cues.

    Full Text Available BACKGROUND Younger age pregnancy of the group 18 years to 19 years is characterized by adverse maternal outcomes like anaemia, hypertension, low birth weight babies and intra uterine growth restriction. A comparative retrospective study on the obstetric outcome in teenage mothers and older women was carried out. Data for the study was obtained from a hospital where considerable teenage pregnancy is reported. Evidence obtained in this study regarding antenatal complications and birth weight shows that good antenatal care and support by family and caregivers can bring down the incidence of anaemia and low birth weight babies in teenage pregnancy. The aim of the study is to compare the obstetric outcome of pregnancy in teenagers and older women in a tertiary care hospital. MATERIALS AND METHODS This was a retrospective study conducted in Government Medical College, Manjeri, Malappuram, Kerala, India for a period of three months from March 2017 to May 2017. This is a teaching hospital with annual delivery rate of around 3500. Obstetric outcome of young mothers in the age group 18 -19 years were compared to older women (20-38 years delivering in the same hospital. A total of 843 deliveries were considered, out of which 87 belonged to teenage group. They were compared in terms of social and educational data, age, number of pregnancy, antenatal care, complications, mode of delivery, birth weight, episiotomy and perineal tears. RESULTS The incidence of teenage pregnancy was fairly high. (10.3% Most of them were in their first pregnancy. A significant number of teenage pregnant mothers (72.4% had completed higher secondary education as compared to (27.6% in older women. Contrary to many prior studies, teenage pregnancies showed less anaemia (6.9% versus 12% and lesser incidence of low birth weight babies in comparison to older women. Preterm birth was higher in teenage group (33.1% and incidence of hypertensive disorders and intrauterine growth

    Full Text Available BackgroundRupture is an important complication of breast implants. Before cohesive gel silicone implants, rupture rates of both saline and silicone breast implants were over 10%. Through an analysis of ruptured implants, we can determine the various factors related to ruptured implants.MethodsWe performed a retrospective review of 72 implants that were removed for implant rupture between 2005 and 2014 at a single institution. The following data were collected: type of implants (saline or silicone, duration of implantation, type of implant shell, degree of capsular contracture, associated symptoms, cause of rupture, diagnostic tools, and management.ResultsForty-five Saline implants and 27 silicone implants were used. Rupture was diagnosed at a mean of 5.6 and 12 years after insertion of saline and silicone implants, respectively. There was no association between shell type and risk of rupture. Spontaneous was the most common reason for the rupture. Rupture management was implant change (39 case, microfat graft (2 case, removal only (14 case, and follow-up loss (17 case.ConclusionsSaline implants have a shorter average duration of rupture, but diagnosis is easier and safer, leading to fewer complications. Previous-generation silicone implants required frequent follow-up observation, and it is recommended that they be changed to a cohesive gel implant before hidden rupture occurs.

    To compare the association between a restrictive transfusion strategy and cardiovascular complications during hospitalization for hip fracture with the association between a liberal transfusion strategy and cardiovascular complications, accounting for all transfusions from the emergency department to postacute rehabilitation settings. Retrospective study. Perioperative geriatric care unit. All individuals aged 70 and older admitted to the emergency department for hip fracture and hospitalized in our perioperative geriatric care unit (N=667; n=193 in the liberal transfusion group, n=474 in the restrictive transfusion group) from July 2009 to April 2016. A restrictive transfusion strategy (hemoglobin level threshold ≥8 g/dL or symptoms) used from January 2012 to April 2016 was compared with the liberal transfusion strategy (hemoglobin level threshold ≥10 g/dL) used from July 2009 to December 2011. Primary endpoint was in-hospital acute cardiovascular complications (heart failure, myocardial infarction, atrial fibrillation or stroke). The change to a restrictive transfusion strategy was associated with fewer acute cardiovascular complications (odds ratio=0.45, 95% confidence interval (CI)=0.31-0.67, pstrategy, Pstrategy than the liberal transfusion strategy (18% vs 9%, Pstrategy in older adults with hip fracture was found to be safe and was associated with fewer cardiovascular complications but more transfusions in rehabilitation settings.

    Very few studies tested the effectiveness of spa therapy in older patients with osteoarthritis. Therefore, we aimed to evaluate the short-term effects of spa therapy in patients aged 65 years and older with generalized, knee, hip, and cervical and lumbar spine osteoarthritis. In an observational retrospective study design at the Medical Ecology and Hydroclimatology Department of Istanbul Medical Faculty, we analyzed the records of 239 patients aged over 65 years with the diagnosis of all types of osteoarthritis who were prescribed a spa therapy course in some spa resorts in Turkey between 7 March 2002 and 31 December 2012. They travelled to a spa resort where they stayed at a thermal spa hotel and followed the usual therapy packages for 2 weeks. Patients were assessed by an experienced physician within a week before the spa journey and within a week after the completion of the spa therapy. Compared with baseline in whole sample, statistically significant improvements were observed in pain (visual analog scale, VAS), patient and physician global assessments (VAS), Health Assessment Questionnaire disability index (HAQ-DI), Lequesne algofunctional index (LAFI) for knee, Western Ontario and McMaster Universities index (WOMAC), Waddell disability index (WDI), and Neck Pain and Disability Scale (NPAD). According to Outcome Measures in Rheumatology—Osteoarthritis Research Society International (OMERACT-OARSI) Set of Responder Criteria, responder rate were 63.8 % (51/80) in generalized, 52 % (13/25) in knee, 50 % (2/4) in hip, 66.7 % (8/12) in lumbar, and 100 % (6/6) in cervical osteoarthritis subgroups. Spa therapy improved pain and physical functional status in older patients with osteoarthritis, especially generalized osteoarthritis and multiple joint osteoarthritis with involvement of knee. This improvement was clinically important in majority of the patients. To confirm the results of this preliminary study, there is a need of a randomized controlled clinical study

    Full Text Available Introduction: Many of the treatment modalities recommended for acromegaly are either too expensive or not available in large parts of India. There is a dearth of treatment and outcome data in Indian patients. Aims and Objectives: The purpose of this study was to analyze the treatment modalities used and the respective outcomes which include remission, recurrence, hypopituitarism, other complications, and mortality. Materials and Methods: This is a retrospective data analysis of 15 acromegaly patients treated at a tertiary care hospital in eastern India. A remission criteria of nadir growth hormone level <1 μg/dl after Oral Glucose tolerance test (OGTT and normal age related IGF-1 levels was used. Results: All patients (100% had macroadenomas. Surgery could not be done in five (33%; three (19.8% refused, two (13.2% had comorbidities. Transsphenoidal surgery (TSS achieved remission in four out of ten (40%. Conventional radiotherapy (CRT failed in all five patients and caused hypopituitarisn in three (60%. Cabergoline (CAB either alone or following surgery achieved remission in one out of four (25% though symptomatic relief and tolerability were remarkable. One patient (7% had pituitary apoplexy with remission, two patients (14.3% died due to CVA. Conclusions: TSS remains the treatment of choice in acromegaly, though in macroadenomas the success is limited. A sizeable proportion of patients refuse or are unfit for surgery. As most of the recommended options are very costly or unavailable, alternative treatment options generally used are CRT or CAB which have limited efficacy. Incidence of hypopituitarism, following CRT is very high.

    The objective of this study is to provide demographical and clinical descriptions of patients age 65 years old and older who were treated with peripheral nerve blocks (PNBs) at our institution and evaluate the safety and efficacy of this treatment. Headache disorders are common, disabling chronic neurological diseases that often persist with advancing age. Geriatric headache management poses unique therapeutic challenges because of considerations of comorbidity, drug interactions, and adverse effects. Peripheral nerve blocks are commonly used for acute and short-term prophylactic treatment for headache disorders and may be a safer alternative to standard pharmacotherapy in this demographic. We performed a single center, retrospective chart review of patients at least 65 years of age who received peripheral nerve blocks for headache management over a 6 year period. Sixty-four patients were mostly female (78%) with an average age of 71 years (range 65-94). Representative headache diagnoses were chronic migraine 50%, episodic migraine 12.5%, trigeminal autonomic cephalalgia 9.4%, and occipital neuralgia 7.8%. Average number of headache days/month was 23. Common comorbidities were hypertension 48%, hyperlipidemia 42%, arthritis 27%, depression 47%, and anxiety 33%. Eighty-nine percent were prescribed at least 1 medication fulfilling the Beers criteria. The average number of peripheral nerve blocks per patient was 4. Peripheral nerve blocks were felt to be effective in 73% for all headaches, 81% for chronic migraine, 75% for episodic migraine, 67% for chronic tension type headache, 67% for new daily persistent headache, and 60% for occipital neuralgia. There were no adverse events related to PNBs reported. PNBs might be a safe and effective alternative headache management strategy for older adults. Medical and psychiatric comorbidities, medication overuse, and Beers list medication rates were extraordinarily high, giving credence to the use of peripherally administered

    Full Text Available BACKGROUND Esophageal achalasia (EA is a primary esophageal motility disorder of unclear aetiology. Standard treatments of EA are: pneumatic balloon dilation (PBD of the lower esophageal sphyncter (LES and surgical cleaving of the muscle by Heller myotomy. Although the treatment effectively cures dysphagia, the symptoms recur in about a half of the patients. Our point of interest was long-term effectiveness of EA treatment at our department. METHODSWe made a retrospective analysis of EA patients treated at our department of thoracic surgery during the 2000–2010 period.RESULTSIn 11 years we performed 187 PBD and 22 laparoscopic myotomies (LM in 148 patients. Three years after the procedure 65 % of patients after PBD and 90 % of patients after LM showed no signs of disease. The risk of recurrence was 3.56-times greater (p = 0.03 after PBD (in comparison to LM, whereas patients older than 50 years bear 0.51-times lower risk (p = 0.02. The most significant complicatios were esophageal perforation in 3 patients (1.6 % after PBD and gastroesophageal reflux in 3 patients (15 % after LM.CONCLUSIONSPBD is a fast, simple, inexpensive and very efficient method of EA treatment, which can be safely performed in almost every patient. LM is far more expensive and a more complicated method that is more suitable for younger patients, in whom PBD is less effective.

    Worldwide, drowning is the second leading cause of unintentional death and the leading cause of cardiovascular failure for children [1-3]. The number of near-drownings, where the incident is survived for at least 24 hours, is assumed to be four times as high [5]. In the years 1994 until 2008 there were 44 cases of drowning treated at the children's department of the University of Leipzig. This number shows that even in a medical centre drowning incidents are only occasional incidents. Therefore it is important to know the sequelae and handlings to be able to react in case of an emergency. A total of 44 children suffering a drowning accident within the last 48 hours who were treated during the period of 01.01.1994 through 30.06.2008 at the Children's Centre at the University of Leipzig. A retrospective analysis using a structured questionnaire was done. Social demographic data, accident progress, clinical results and progress as well as outcome of the cases were investigated. During the analysed period in the median three children were treated each year after drowning incidents. Clustering in the summer and winter months and on the weekends was recognizable. The median age was 3.33 years and the group of high risk were children aged 1-3 years, especially boys. Sixty percent of the children came from stable social backgrounds. Half of the children suffered from drowning in created swimming pools or ponds, the rest in natural waters, public pools and sources of water in the household. The median submersion lasted 2 minutes. Correlation of submersions below 1 minute with a good, and submersions above 10 minutes with a negative outcome was shown. A Glasgow Coma Scale (GCS) of 3 points (n = 15) and pupils without light reaction (n = 14) were associated with a lethal outcome or residual neurological deficits. Looking at the laboratory values, correlation between severe acidotic pH-values with a very low base excess, high blood sugar as well as high lactate values and a

    Pneumonia is one of the major causes of mortality in older adults. As the average lifespan has extended and new modalities to prevent or treat pneumonia are developed, the factors that affect the length of hospital stay (LHS) and in-hospital mortality of older patients with pneumonia have changed. The object of the present study was to determine the factors associated with LHS and mortality as a result of pneumonia among older patients with dementia. With a retrospective cohort study design, we used the data derived from the Japanese Administrative Database and diagnosis procedure combination/per diem payment system (DPC/PDPS) database. There were 39 336 admissions of older patients for pneumonia between August 2010 and March 2012. Patients with incomplete data were excluded, leaving 25 602 patients for analysis. Having dementia decreased mortality (OR 0.71, P LHS. Multiple logistic regression analysis identified donepezil as an independent factor that decreased mortality in patients with dementia (OR 0.36, P LHS and mortality were similar to those reported by others. Donepezil seems to decrease in-hospital mortality as a result of pneumonia among older patients with dementia. Geriatr Gerontol Int 2018; 18: 269-275. © 2017 Japan Geriatrics Society.

    Emergency services manage trauma patients frequently and falls from height comprise the main cause of emergency service admissions. In this study, we aimed to analyse the demographic characteristics of falls from height and their relationship to the mortality. A total of 460 patients, who admitted to the Emergency Department of Inonu University between November 2011 and November 2014 with a history of fall from height, were examined retrospectively. Demographic parameters, fall characteristics and their effect to mortality were evaluated statistically. The study comprised of 292 (63.5%) men and 168 (36.5%) women patients. The mean age of all patients was 27±24.99 years. Twenty-six (5.6%) patients died and the majority of them were in ≥62 years old group. The highest percentage of falls was at 0-5 years age group (28.3%). People fell mainly from 1.1-4 metres(m) level (46.1%). The causes of falls were ordered as unintentional (92.2%), workplace (8.1%) and suicidal (1.7%). Skin and soft tissue injuries (37.4%) were the main traumatic lesions. Age, fall height, fall place, lineer skull fracture, subarachnoidal hemorrhage, cervical fracture, thoracic vertebra fracture and trauma scores had statistically significant effect on mortality. The casualties died because of subarachnoid hemorrhage mostly.

    Full Text Available Aim: The prevalence of epilepsy is higher in Nepal. This study was conducted to analyze the clinical manifestations of neurocysticercosis (NCC among seizure patients admitted to our center. Methods: We retrospectively studied all the NCC patients admitted to Neurology Department, Bir Hospital, Kathmandu, Nepal from April 2012 to February 2014. Computer tomography/magnetic resonance imaging (CT/MRI head, clinical profile, lab investigations and exclusion of other causes were the basis of the NCC diagnosis. Chi-square and Student′s t-test were used for comparison of variables. Results: Out of 131 seizure patients admitted, 21 patients were diagnosed with NCC (mean age: 33.95 ± 16.41; male: 15 (71.4%, female: 6 (28.6%. Generalized tonic clonic seizure was the most common seizure type in NCC patients (18 patients; 85.7%, two of them had status epilepticus during presentation in Emergency Department. Three patients had focal seizure, one with epilepsia partialis continua. Neuroimaging showed multiple NCC lesions in 8 (38.1% and a single NCC lesion in 13 (61.9% patients. Seven of them (33.3% sought traditional healers before being presented to our center. Eight patients (38.1% were treated with antiepileptics in local health-post without neuroimaging studies done. Calcified stage of NCC was the most frequent CT/MRI findings (12 patients; 57.1%. Phenytoin was preferred both by physicians and patients due to its low cost. Conclusion: NCC is a common finding among seizure patients in Nepal. Poor economic status, illiteracy and underdeveloped rural society are the major challenges in prevention and treatment of NCC.

    The purpose of this study was to see whether differences emerge between older whites, older blacks, and older Mexican Americans in 12 measures of prayer. These measures assess four dimensions of prayer: The social context of prayer, interpersonal aspects of prayer, beliefs about how prayer operates, and the content or focus of prayers. Data from two nationwide surveys of older adults suggest that with respect to all four dimensions, the prayer lives of older whites appear be less developed than the prayer lives of older blacks and older Mexican Americans. In contrast, relatively few differences were found in the prayer lives of older African Americans and older Mexican Americans. The theoretical implications of these findings are discussed.

    our objective was to determine the incidence of toxicity among veterans initiating isoniazid therapy for latent tuberculosis infection (LTBI) and determine whether advancing age was a risk factor for toxicity. we performed a retrospective cohort study among all adults initiating isoniazid treatment for LTBI at a Veterans Medical Center from 1999 to 2005. We collected data on patient demographics, co-morbidities, site of initiation, and treatment outcome. 219 patients initiated isoniazid therapy for LTBI during the period of observation, and the completion of therapy was confirmed in 100 patients (46%). Among 18/219 patients (8%) that discontinued therapy due to a documented suspected toxicity, the median time to onset was 3 months (IQR 1-5 months). In an adjusted Cox regression model, there was no association between discontinuation due to suspected toxicity and advancing age (HR 1.03, 95% CI 0.99, 1.07). In contrast, hepatitis C infection was a significant predictor of cessation due to toxicity in the adjusted analysis (HR 3.03, 95% CI 1.08, 8.52). cessation of isoniazid therapy due to suspected toxicity was infrequently observed among a veteran population and was not associated with advancing age. Alternative LTBI treatment approaches should be further examined in the veteran population.

    Full Text Available Background. While behavioral and psychological symptoms are frequent in hospitalized older adults with dementia or delirium, data supporting the off-label use of intramuscular atypical antipsychotics remain scarce. We examined the use of short-acting intramuscular (IM olanzapine in hospitalized older adults to manage behavioral and psychological symptoms. Methods. A retrospective observational study of inpatients 65 years or older with at least one order for olanzapine IM during admission in urban Ontario Canada was conducted. Patient demographics, prescriptions for olanzapine IM, reason for administration, perceived effectiveness, adverse events, concurrently prescribed psychotropics, comorbidities, and patient discharge destination were recorded. Results. Among 82 patients aged 65–96 years (mean ± SD 79.3 ± 7.7 85 cases were identified. Cognitive impairment or dementia affected 63.5% and 50.6% had comorbidities. Olanzapine IM was ordered 102 times and 34 patients (41% received at least one dose. The intended efficacy was achieved in 79.4% of 78 cases of 124 doses given (62.9%. Fourteen (41% patients who received doses experienced adverse events, with sedation and hypotension being the most common. Conclusions. Olanzapine IM appears effective in hospitalized older adults but is associated with potential adverse events. Structured monitoring and documentation are needed to ensure safe use in this high-risk population.

    The aim was to explore the association between retrospectively assessed psychosocial working conditions during working life and prospectively assessed risk of sickness absence and disability pension among older workers. The prospective risk of register-based long-term sickness absence (LTSA) and disability pension was estimated from exposure to 12 different psychosocial work characteristics during working life among 5076 older workers from the CAMB cohort (Copenhagen Aging and Midlife Biobank). Analyses were censored for competing events and adjusted for age, gender, physical work environment, lifestyle, education, and prior LTSA. LTSA was predicted by high levels of cognitive demands (HR 1.31 (95% CI 1.10-1.56)), high levels of emotional demands (HR 1.26 (95% CI 1.07-1.48)), low levels of influence at work (HR 1.30 (95% CI 1.03-1.64)), and high levels of role conflicts (HR 1.34 (95% CI 1.09-1.65)). Disability pension was predicted by low levels of influence at work (HR 2.73 (95% CI 1.49-5.00)) and low levels of recognition from management (HR 2.04 (95% CI 1.14-3.67)). This exploratory study found that retrospectively assessed high cognitive demands, high and medium emotional demands, low influence at work, low recognition from management, medium role clarity, and high role conflicts predicted LTSA and/or disability pension.

    Despite guidelines suggesting a 25-50 % reduction in induction doses of intravenous anesthetic agents in the elderly (≥65 years), we hypothesized that practitioners were not sufficiently correcting drug administration for age, contributing to an increased incidence of hypotension in older patients undergoing general anesthesia. We conducted a retrospective, observational study in a tertiary-care academic hospital. The study included 768 female patients undergoing gynecologic surgeries who received propofol-based induction of general anesthesia. Weight-adjusted anesthetic induction dosing, age-associated differences in dosing by ASA-PS (American Society of Anesthesiology-Physical Status), and hemodynamic outcomes between younger (18-64 years, n = 537) and older (≥65 years, n = 231) female patients were analyzed. Older patients received lower doses of propofol and midazolam than younger patients (propofol: 2.037 ± 0.783 vs 2.322 ± 0.834 mg/kg, p < 0.001; midazolam: 0.013 ± 0.014 vs 0.023 ± 0.042 mg/kg, p < 0.001). However, practitioners still consistently exceeded the FDA recommended dose (1-1.5 mg/kg) of propofol for elderly patients. There was no significant difference in the doses of fentanyl administered between the two age groups (1.343 ± 0.744 vs 1.363 ± 0.763 μg/kg, p = 0.744), and doses of fentanyl in older patients exceeded the recommended dose (0.5-1.0 μg/kg). Corresponding to observed overdosing of induction agents, older patients experienced larger decreases in post-induction blood pressure and were more likely to receive vasopressor therapy. Anesthetic induction doses of fentanyl and propofol were not sufficiently corrected in older patients in accordance with recommendations. Significantly greater frequency of post-induction hypotension occurred amongst older patients. Quality improvement efforts may lead to improved outcomes in this vulnerable population.

    Full Text Available Abstract Background Sweden has closed all institutions and imposed legislation to ensure service and support for individuals with intellectual disability (ID. Understanding mortality among older individuals with ID is essential to inform development of health promotion and disease control strategies. We investigated patterns and risk of mortality among older adults with ID in Sweden. Methods This retrospective cohort study compared older adults aged 55 years and older with ID with a control population. Participants were followed during 2002–2015 or death, and censored if they moved out of Sweden. Individuals with ID were identified from two national registers: one covering all specialist health-care visits (out-patient visits and hospitalisation and the other covering people accessing social/support services. Individuals with ID (n = 15,289 were matched with a control population by sex, birth year, and year of first hospitalisation/out-patient visit/access to LSS services. Cause-of-death data were recorded using International Classification of Diseases, Tenth Revision. Cox proportional hazards regression were conducted to assess if overall and cause-specific mortality rate among individuals with ID was higher than in the Swedish population. Results The overall mortality rate among individuals with ID was 2483 per 100,000 people compared with 810 in the control population. Among those who died, more individuals with ID were younger than 75 years and unmarried. Leading causes of death among individuals with ID were circulatory diseases (34%, respiratory diseases (17% and neoplasms (15%. Leading causes of death in a sub-sample with Down syndrome (DS were respiratory diseases (37%, circulatory diseases (26% and mental/behavioural disorders (11%. Epilepsy and pneumonitis were more common among individuals with ID than controls. Alzheimer’s disease was common in the control population and individuals with DS, but not among those with ID when

    Objective To determine the prospective association between retrospectively assessed physical work environment during working life and prospectively assessed sickness absence and labour market exit among older workers. Methods Using Cox regression analyses we estimated the 4-year to 6-year prospective risk of register-based long-term sickness absence (LTSA), disability pension, early retirement and unemployment from exposure to different physical work environmental factors during working life among 5076 older workers (age 49–63 at baseline) from the Copenhagen Aging and Midlife Biobank cohort. Results Very hard physical work throughout working life was a risk factor for LTSA (HR 1.66,95% CI 1.32 to 2.07), disability pension (HR 2.21,95% CI 1.04 to 4.72) and early retirement (HR 1.57,95% CI 1.13 to 2.17). Both short-term (work during working life and exposure to several factors in the physical work environment, especially heavy lifting, were important for labour market exit and sickness absence. This study underscores the importance of reducing physical work exposures throughout the working life course for preventing sickness absence and premature exit from the labour market. PMID:28819019

    Fall-related deaths continue to be the leading cause of accidental deaths in the older adult (65+ year) population. However, many fall-related fatalities are unspecified and little is known about the fall characteristics and personal demographics at the time of the fall. Therefore, this report describes the characteristics, circumstances and injuries of falls that resulted in older adult deaths in one U.S. County and explores the variables associated with fatal injuries from falls. This is a continued retrospective analysis of 841older adults whose underlying cause of death was due to a fall over an 8-year period (2005-2012). Demographics and logistic regression of fall characteristics and injuries were analyzed. Falls that led to death most often occurred when walking in one's own home. Most of the residents in this study were community-dwellers who had previous comorbidities taking an average of six medications prior to their fall. Survival after a fall was on average 31 days. The two most common injuries after a fatal fall were hip fractures (54%), and head injuries (21%). A logistic regression identified two variables associated with hip fracture, advancing age (OR = 1.05, 95% confidence interval [CI] = 1.02-1.08) and diagnosis of a prior neurological condition (OR = 2.1, 95% CI = 1.4-3.1). Variables associated with head injuries included younger age (OR = .91, 95% CI = .89-.94), male gender (OR = 2.5, 95% CI = 1.7-3.8), prescribed anticoagulants (OR = 2.4, 95% CI = 1.5-3.9) and negative musculoskeletal comorbidity (OR = 1.9. 95% CI = 1.1-3.0). Hip fractures and head injuries were the most common injury after a fall that led to death in older adults greater than 65 years. There are opposing risk factors for older adults who incur a hip fracture compared to a head injury. Thus, health professionals will need to individualize prevention efforts to reduce fall fatalities.

    Francisco José Tortosa Vallecillos

    Full Text Available SUMMARY Objective: As a result of the use of neuroimaging techniques, silent pituitary lesions are diagnosed more and more frequently; however, there are few published post-mortem studies about this gland. Incidence data of pituitary lesions are rare and in Portugal they are outdated or even non-existent. The aim of this study is to determine the prevalence of normal patterns and incidental post-mortem pituitary pathology at Centro Hospitalar Lisboa Norte, analyzing the associations with clinical data and assessing the clinical relevance of the findings. Method: We reviewed retrospectively and histologically 167 pituitaries of a consecutive series of autopsies from the Department of Pathology of this centre. They were done between 2012 and 2014, and in all cases medical records were reviewed. The morphological patterns observed, were classified into three major groups: 1 Normal histological patterns and variants; 2 Infectious-inflammatory pathology, metabolic and vascular disorders; 3 Incidental primary proliferation and secondary to systemic diseases. Results: The subjects included in this study were of all age groups (from 1 day to 91 years old, 71 were female and 96 male. Fifty-seven of these glands didn’t show any alteration; 51 showed colloid cysts arising from Rathke cleft; 44 presented hyperplasia in adenohypophysis and we identified 20 adenomas in 19 glands (immunohistochemically, eight PRL-producing and five ACTH-producing tumors, ten of which associated with obesity, 11 to hypertension and six to diabetes mellitus. There were two cases with metastasis. Conclusion: Subclinical pathology in our country is similar to that seen in other parts of the world, but at older ages.

All HIV-infected individuals, except pregnant or breastfeeding women, aged ≥ 25 years at ART initiation between 2006 and 2015 were included. Poisson regression models estimated risk of mortality, stratified by age groups.Of 37,378 ART patients, 3,406 were ≥ 50 years old. Patients aged ≥ 50 years initiated ART with more advanced WHO clinical stage and lower CD4 cell count than their younger counterparts. Older patients had a significantly slower immunological response to ART in the first 18 months on ART compared to patients aged 25-39 years (p = 0.04.

Overall LTFU rates were 6.3 (95% CI 6.1-6.5, 4.5 (95% CI 4.2-4.7, and 5.6 (95% CI 5.1-6.1 per 100 person years among increasing age cohorts. The proportion of patients aged ≥ 50 years and newly enrolling into ART care remained stable at 9% while the proportion of active ART patients aged ≥50 years increased from 10% in 2006 to 15% in 2015.Older people had slower immunological response and higher mortality. Malawi appears to be undergoing a demographic shift in people living with HIV. Increased consideration of long-term ART-related problems, drug-drug interactions and age-related non-communicable diseases is warranted.

    Based on a retrospective analysis of the drunk driving cases, to explore the drunk drivers' personnel composition, occurrence time and psychology. As a result of punishment of the drunk driving by criminal law for one year from May 1st, 2011 to April 30th, 2012, 91 drunk driving cases were statistically analyzed the easy-happening time of drunk driving, the drunk drivers' age, gender, occupational characteristics, domicile and psychological factors. In 97 drunk driving cases, 26-40 years old, non-local domiciled and non-professional male drivers were prone to drunk driving at night from 22:00 to 5:00. The behavior of drunk driving is relevant to time, age, genders and occupation. The psychological characteristics of most drivers are fluky, making-life-easy, competitive and peacockish.

    Full text: IMRT has been implemented into clinical practice at Royal Hobart Hospital (RHH) since mid 2006 for treating patients with Head and Neck (H and N) or prostate tumours. A local quality assurance (QA) acceptance criteria based on 'gamma distribution' for approving IMRT plan was developed and implemented in early 2007. A retrospective analysis of such criteria over 194 clinical cases will be presented. The RHH IMRT criteria was established with assumption that gamma distribution obtained through inter-comparison of 2 D dose maps between planned and delivered was governed by a positive-hail' normal distribution. A commercial system-MapCheck was used for 2 D dose map comparison with a built-in gamma analysis tool. Gamma distribution histogram was generated and recorded for all cases. By retrospectively analysing those distributions using curve fitting technique, a statistical gamma distribution can be obtained and evaluated. This analytical result can be used for future IMRT planing and treatment delivery. The analyses indicate that gamma distribution obtained through MapCheckTM is well under the normal distribution, particularly for prostate cases. The applied pass/fail criteria is not overly sensitive to identify 'false fails' but can be further tighten-up for smaller field while for larger field found in both H and N and prostate cases, the criteria was correctly applied. Non-uniform distribution of detectors in MapCheck and experience level of planners are two major factors to variation in gamma distribution among clinical cases. This criteria derived from clinical statistics is superior and more accurate than single-valued criteria for lMRT QA acceptance procedure. (author)

    Full Text Available The needle trace method (NTM, created and developed by the Finnish forest pathologists prof. T. Kurkela, dr. R. Jalkanen and T. Aalto during the last decade of the XX century, has been already used by several researchers of different countries for retrospective analysis of needle diseases (Hypodermella sulcigena, by R. Jalkanen et al. in Finland or herbivorous insect pests of Scots pine (Diprion pini, by T. Kurkela et al. in Finland; Bupalus piniaria, by H. Armour et al. in Scotland, but as well of pests of Sitka spruce (Gilpinia hercyniae, by D.T. Williams et al. in England. Scots pine in forest nurseries and young plantations of Estonia is often but irregularly suffering from the epidemics of the needle cast fungus Lophodermium seditiosum. Current environmental regulations exclude from the regulatory (control measures all the others except of well-argued prophylactic systems, built up on reliable prognoses. The last is inconceivable without the availability of a reliable, as well, and long-lasting retrospective time-series of L. seditiosum epidemics, which, as it is known from the last half of the XX century, are occupying large forest areas, usually not least than a half of (the small Estonia. An appropriate time-series would be useful, as well, for the more basic understanding of the accelerated mortality processes during the stand formation in early pole-age Scots pine plantations. Methodological principles of the use of NTM in an appropriate investigation together with the preliminary results of our research work, looking back for more than a century, are introduced and discussed in this investigation.

    Full Text Available Pancreatic pseudocysts arise mostly in patients with alcohol induced chronic pancreatitis causing various symptoms and complications. However, data on the optimal management are rare. To address this problem, we analysed patients with pancreatic pseudocysts treated at our clinic retrospectively.We searched our clinical database for the diagnosis pancreatitis from 2004 till 2014, selected patients with pseudocysts larger than 10 mm and entered all relevant information in a database for statistical analysis.In total, 129 patients with pancreatic pseudocysts were treated at our institution during the study period. Most patients suffered from alcohol induced chronic pancreatitis (43.4%; 56/129. Pseudocysts were more frequent in female than in male (2:1 and were mainly located in the pancreatic head (47.3%; 61/129. Local complications like obstructive jaundice were associated with the diameter of the cysts (AUC 0.697 in ROC-curve analysis. However, even cysts up to a diameter of 160 mm can regress spontaneously. Besides a lower re-intervention rate in surgically treated patients, endoscopic, percutaneous and surgical drainage are equally effective. Most treatment related complications occur in large pseudocysts located in the pancreatic head.Conservative management of large pseudocysts is successful in many patients. Therefore, indication for treatment should be made carefully considering the presence and risk of local complications. Endoscopic and surgical drainage are equally effective.

    Purpose: To determine the impact of postoperative radiation therapy (POXRT) on outcome in spinal cord gliomas. Patients and Methods: Data from 242 patients were collected retrospectively from six institutions using a standardized data sheet. Pathology specimens, when available, were centrally reviewed. Results: A total of 183 patients were analyzed: 82 received surgery alone as initial treatment, whereas 101 had surgery and POXRT. Demographic, diagnostic, and treatment factors were analyzed for impact on progression-free (PFS) and overall survival (OS). PFS in ependymoma patients was 74%, 60%, and 35% at 5, 10, 15 years, respectively, and was significantly influenced by treatment type, race, age, tumor grade, and type of surgery on univariate analysis, with age being the only significant factor on multivariate analysis (MVA) (p = 0.01). OS of ependymoma patients was 91%, 84%, and 75% at 5, 10, and 15 years, respectively, and was significantly influenced by both complete resection (p = 0.04) and age (p = 0.03) on MVA. In astrocytomas, PFS was 42%, 29%, and 15% at 5, 10, and 15 years, and was significantly influenced by POXRT in low- and intermediate-grade tumors on MVA (p = 0.02). OS at 5, 10, and 15 years was 59%, 53%, and 32%, respectively, and was significantly influenced by grade on MVA (p < 0.01). Conclusion: Postoperative radiation therapy reduced disease progression in low- and moderate-grade astrocytomas. In ependymomas, complete resection significantly influenced OS

    The main aim of a radiation epidemiological study is to assess the risk of the population exposed to ionizing radiation. The actual work of the assessment may be very difficult because dose information about the population is often indirect and incomplete. It is very important, therefore, to find a way of estimating reasonable and reliable doses of the population by a retrospective method from limited information. In order to provide reasonable dose information for the cohort study of Chinese medical diagnostic X-ray workers, a retrospective dosimetry method was established. In China, a cohort study of more than 27,000 medical diagnostic X-ray workers, with 25,000 controls, has been carried out for about fifteen years in order to assess the risk to an occupationally exposed population. Obviously, a key to the success of the study is to obtain reliable and reasonable results of dose estimation by the dose reconstruction method. Before 1985, there was a lack of information regarding personal dose measured directly; however, we can obtain other indirect information. Examples are information about working loads from the documents of the hospitals, information about operational conditions of the workers of different statuses by a survey of occupational history, and the exposure levels of various working conditions by some simulation methods. The information for estimating organ dose can also be obtained by simulating experiments with a phantom. Based on the information mentioned above, a mathematical model and computerizing system for dose reconstruction of this occupational population was design and developed. Uncertainty analysis very important for dose reconstruction. The sources of uncertainty of our study are coming from two fields. One is coming from the mode of dose reconstruction. Another is coming from the survey of the occupational history. In the result reported, main results of the uncertainty will be presented. In order to control the uncertainty of the

    Full Text Available Background: Developing countries at tertiary referral centre. The aim of this study was to share our experience of paediatric achalasia in Indian scenario. Materials and Methods: This was a retrospective analysis of children <16 years, operated for achalasia at our centre, from December 1998 to December 2011. Results: Total 40 patients (mean age 39 ± 4.29 months, including 1 patient of megaesophagus were operated over 13 years of period; 17 patients (associated congenital H-type tracheoesophageal fistula in one patient, non- responders/ lost follow-up for minimum of 3 years in 16 patients were excluded from the study. The response rate of parents in follow-up was 60.0%. Mean symptoms duration was 27.88 ± 2 months. Most common symptoms were regurgitation and failure to thrive (78.2%. Mean symptom scoring in follow-up after 3 year was 1 ± 0.7 compared to 5 ± 0.51 at the time of admission (P < 0.012. One infant expired (mediastenitis, one developed adhesive intestinal obstruction and one needed posterior re-myotomy (for megaesophagus. There were no treatment failures in mean follow-up of 40.2 ± 5.07 months. Conclusions: Cardiomyotomy with partial fundoplication is the best modality of treatment for paediatric achalasia cardia, even from parents′ perspective.

    This report presents a retrospective analysis of the authors' experience with occipitocervical fusions in children and adolescents during the last 2 decades. A description of an operative technique devised by the senior author (JEH), and a comparison of the results using this and other methods of fusion are given. Twenty-three patients underwent occipitocervical fusion. Fifteen of the patients were operated on using the authors' technique. To achieve stable fixation of the distal cervical vertebra a threaded Kirschner wire was passed transversely through the spinous process; occipital fixation was achieved by the traditional method of wiring corticocancellous bone graft to the skull through burr holes. The occipital wires then were wrapped around the Kirschner wire and the graft was cradled in the resulting nest. Halo immobilization was used in 10 patients for an average of 12.5 weeks (range, 6-24 weeks). Twenty-two patients achieved successful fusion at an average followup of 5.8 years (range, 1-14.33 years). Several complications, including transient quadriplegia in one patient, pseudarthrosis in two (one of which persists), hardware fixation failure in one, unintended distal extension of the fusion, pneumonia, wound infection, halo pin infection, skin breakdown under the halo vest, hydrocephalus, cerebrospinal fluid leak, and traumatic fusion fracture were encountered. Results using the technique described herein are comparable with or better than the results reported in the previous literature, and the results of the patients in this series in whom the technique was not used.

    Tritium analyses of tree-ring cellulose were made to test its suitability for retrospective evaluation of a local tritium fallout. Several spruce trees were taken from an Austrian alpine area where tritium contamination of May 1974 precipitation had been detected. Wood from the annual growth rings of 1973, 1974 and 1975 was separated and the cellulose extracted. After isotopic equilibration with dead water, cellulose was combusted to yield water, whose tritium concentration was measured by liquid scintillation counting. Rigorous statistical treatment proved the significance of the increased tritium concentration caused by the tritium anomaly, which occurred during the growing season. The long-term trends of local atmospheric tritium, including the 1974 peak, were also well reflected by analysis of a 24-year ring sequence from a single tree in the contaminated area. The tritium data gained by the given method can be used at present qualitatively and a better understanding of the possible sources of contamination is required in order that the quantitative criteria be satisfied.

    Full Text Available Background: The management of odontoid fracture has evolved but controversy persists as to the best method for Type II odontoid fractures with or without atlantoaxial (AA instability. The anterior odontoid screw fixation can be associated with significant morbidity while delayed odontoid screw fixation has shown to be associated with reasonable good fusion rates. We conducted a retrospective analysis to evaluate the outcome of a trial of conservative management in type II odontoid fractures without atlantoaxial instability (Group A followed by delayed odontoid screw fixation in cases in which fusion was not achieved by conservative treatment. The outcome of type II odontoid fracture with AA subluxation (Group B was also analysed where closed reduction on traction could be achieved and in those atlantoaxial subluxations that were irreducible an intraoperative reduction was done. Materials and Methods: A retrospective evaluation of 53 cases of odontoid fractures treated over a 9-year period is being reported. All odontoid fractures without AA instability (n=29 were initially managed conservatively. Three patients who did not achieve union with conservative management were treated with delayed anterior screw fixation. Twenty-four cases of odontoid fractures were associated with AA instability; 17 of them could be reduced with skeletal traction and were managed with posterior fusion and fixation. Of the seven cases that were irreducible, the initial three cases were treated by odontoid excision followed by posterior fusion and fixation; however, in the later four cases, intra operative reduction was achieved by a manipulation procedure, and posterior fusion and fixation was performed. Results: Twenty-six of 29 cases of odontoid fracture without AA instability achieved fracture union with conservative management whereas the remaining three patients achieved union following delayed anterior odontoid screw fixation. 17 out of 24 odontoid fracture with

    Human dignity is an essential value of professional nursing education as well as a component of the American Nurses Association Code of Ethics. Nurses are exhorted to treat patients with dignity, and older adults want to be treated with dignity and die with dignity. Although dignity, particularly the dignity of older adults, is often discussed in the health care literature, its meaning is not always clear. The aim of this paper is to describe a concept analysis to develop a definition of dignity in older adults. Data were collected using a literature review and five focus groups composed of older adults. The literature provided data about professionals' ideas of dignity and the focus groups provided qualitative data about the nature of dignity in older people. The literature review and focus groups were carried out concurrently, followed by synthesis of the findings. Dignity is an inherent characteristic of being human, it can be subjectively felt as an attribute of the self, and is made manifest through behaviour that demonstrates respect for self and others. Dignity must be learned, and an individual's dignity is affected by the treatment received from others. A behavioural definition of dignity was constructed and this could provide the theoretical basis for nurses to develop interventions that foster dignity for older people.

    Self-determination has emerged as an important concept within health care, used to emphasize clients' control and independence as they participate in rehabilitation. To strengthen clients' self-determination is a central aim in occupational therapy. However, there is a lack of a clear definition of self-determination concerning community-dwelling older people. The definition should be flexible in different contexts, such as cultural. To define and clarify the concept of self-determination in relation to community-dwelling frail older people. Walker & Avant's analysis procedure was carried out to identify textual attributes to the concept of self-determination, supplemented by a content analysis of 21 articles that were used to define and further justify the textual attributes. Self-determination was used in diverse contexts for community-dwelling older people, concerning: decision-making in everyday life, professionals' views, health, and legal/ethical rights. Different textual attributes were identified, to propose a conceptual definition of self-determination in relation to community-dwelling frail older people: A process in which a person has control and legal/ethical rights, and has the knowledge and ability to make a decision of his/her own free choice. This concept analysis has contributed to clarifying the concept for the convenience of research with community-dwelling frail older people.

    Full Text Available Virechana (therapeutic purgation is a common procedure that is widely practiced among the panchakarma treatments (pentad treatments. Various Virechaka dravyas (purgative drugs have been described for Virechana. Even after critical analysis of Virechaka dravyas in the literature, still there is difficulty in the fixation of dose. Hence, the retrospective analysis of varied outcomes of Virechana with Danti (Baliospermum montanum avaleha (linctus is discussed in this paper. The study included twenty-seven case reports of patients who were administered Virechana with Danti avaleha. These case reports are of patients suffering from various ailments such as irregular menstrual cycles, polycystic ovarian syndrome, primary and secondary infertility, and psoriasis. Danti avaleha was administered at dose of 10 g and 5 g in the Krura (~strong and Madhyama (~moderate/normal Koshta (~GI tract patients, respectively. Among seven Krura koshta patients, three of them resulted with Pravara (excellent Shuddhi and other four resulted with Madhyama (medium Shuddhi. In twenty Madhyama koshta patients, sixteen of them resulted with avara (minimum Shuddhi and remaining four patients resulted with Madhyama shuddhi. Complications like Udara shoola (spasmodic pain of abdomen and Vamana (emesis were observed during Virechana. Majority of the patients suffered with Udara shoola were of Madhyama koshta. Vamana was seen in both Krura and Madhyama koshta patients. Irrespective of the type of Shuddhi and complications, all the patients resulted with Samyak Kaphaantiki Virikta lakshana (signs of perfect purgation with end expulsion of Kapha. The study concluded that the Krura koshta patients were tolerable for dose of 10 g and are expected to attain Pravara Shuddhi. Whereas Madhyama koshta patients were intolerable even to mild dose of 5 g, producing Avara shuddhi.

    Adult medulloblastoma is a rare disease treated according to the current pediatric treatment guidelines. This retrospective analysis investigated the clinical outcomes and prognostic factors of adult medulloblastoma patients, who received multimodal therapy at our institution. Treatment charts of all patients over the age of 15 years of age with de novo medulloblastoma, who had been treated at our institution between 2001 and 2014, were retrospectively analyzed. Patients' demographic parameters, initial symptoms, treatment modalities, toxicities, and survival outcomes were investigated. In all, 21 patients with a median age of 30.2 years were identified. The most frequent histologies were desmoplastic and classic, and the most common molecular subtype was sonic hedgehog (SHH). After tumor resection, all patients received craniospinal irradiation (median dose 35.2 Gy) and a boost to the posterior fossa (median dose 19.8 Gy). Simultaneous chemotherapy with vincristine was given to 20 patients and sequential chemotherapy to 15 patients. The most common side effects were hematological toxicities. Median overall survival (OS) has not been reached after a median follow-up of 92 months. Estimated 5- and 10-year OS was 89 and 80%, respectively. Estimated 5- and 10-year progression-free survival (PFS) was 89 and 81%, respectively. In univariate analysis, a shorter interval between tumor resection and end of irradiation was significantly associated with improved OS and PFS, anaplastic histology with worse OS and PFS. The combined modality treatment showed a good outcome in adults with medulloblastoma. Treatment time was revealed to be prognostic and should be kept as short as possible. (orig.)

    Objective To assess the mortality risk in subsequent years (adjusted for year of birth, nationality, and sex) of former Olympic athletes from disciplines with different levels of exercise intensity. Design Retrospective cohort study. Setting Former Olympic athletes. Participants 9889 athletes (with a known age at death) who participated in the Olympic Games between 1896 and 1936, representing 43 types of disciplines with different levels of cardiovascular, static, and dynamic intensity exercise; high or low risk of bodily collision; and different levels of physical contact. Main outcome measure All cause mortality. Results Hazard ratios for mortality among athletes from disciplines with moderate cardiovascular intensity (1.01, 95% confidence interval 0.96 to 1.07) or high cardiovascular intensity (0.98, 0.92 to 1.04) were similar to those in athletes from disciplines with low cardiovascular intensity. The underlying static and dynamic components in exercise intensity showed similar non-significant results. Increased mortality was seen among athletes from disciplines with a high risk of bodily collision (hazard ratio 1.11, 1.06 to 1.15) and with high levels of physical contact (1.16, 1.11 to 1.22). In a multivariate analysis, the effect of high cardiovascular intensity remained similar (hazard ratio 1.05, 0.89 to 1.25); the increased mortality associated with high physical contact persisted (hazard ratio 1.13, 1.06 to 1.21), but that for bodily collision became non-significant (1.03, 0.98 to 1.09) as a consequence of its close relation with physical contact. Conclusions Among former Olympic athletes, engagement in disciplines with high intensity exercise did not bring a survival benefit compared with disciplines with low intensity exercise. Those who engaged in disciplines with high levels of physical contact had higher mortality than other Olympians later in life. PMID:23241269

    2017-07-01

    Full Text Available IntroductionRestless legs syndrome (RLS is a prevalent sleep disorder affecting quality of life and is often comorbid with other neurological diseases, including peripheral neuropathy. The mechanisms related to RLS symptoms remain unclear, and treatment options are often aimed at symptom relief rather than etiology. RLS may present in distinct phenotypes often described as “primary” vs. “secondary” RLS. Secondary RLS is often associated with peripheral neuropathy. Nerve decompression surgery of the common and superficial fibular nerves is used to treat peripheral neuropathy. Anecdotally, surgeons sometimes report improved RLS symptoms following nerve decompression for peripheral neuropathy. The purpose of this retrospective analysis was to quantify the change in symptoms commonly associated with RLS using visual analog scales (VAS.MethodsForty-two patients completed VAS scales (0–10 for pain, burning, numbness, tingling, weakness, balance, tightness, aching, pulling, cramping, twitchy/jumpy, uneasy, creepy/crawly, and throbbing, both before and 15 weeks after surgical decompression.ResultsSubjects reported significant improvement among all VAS categories, except for “pulling” (P = 0.14. The change in VAS following surgery was negatively correlated with the pre-surgery VAS for both the summed VAS (r = −0.58, P < 0.001 and the individual VAS scores (all P < 0.01, such that patients who reported the worst symptoms before surgery exhibited relatively greater reductions in symptoms after surgery.ConclusionThis is the first study to suggest improvement in RLS symptoms following surgical decompression of the common and superficial fibular nerves. Further investigation is needed to quantify improvement using RLS-specific metrics and sleep quality assessments.

    The test reports for the RF-induced heating of metallic devices of hundreds of medical implants have been provided to the U.S. Food and Drug Administration as a part of premarket submissions. The main purpose of this study is to perform a retrospective analysis of the RF-induced heating data provided in the reports to analyze the trends and correlate them with implant geometric characteristics. The ASTM-based RF heating test reports from 86 premarket U.S. Food and Drug Administration submissions were reviewed by three U.S. Food and Drug Administration reviewers. From each test report, the dimensions and RF-induced heating values for a given whole-body (WB) specific absorption rate (SAR) and local background (LB) SAR were extracted and analyzed. The data from 56 stents were analyzed as a subset to further understand heating trends and length dependence. For a given WB SAR, the LB/WB SAR ratio varied significantly across the test labs, from 2.3 to 11.3. There was an increasing trend on the temperature change per LB SAR with device length. The maximum heating for stents occurred at lengths of approximately 100 mm at 3 T, and beyond 150 mm at 1.5 T. Differences in the LB/WB SAR ratios across testing labs and various MRI scanners could lead to inconsistent WB SAR labeling. Magnetic resonance (MR) conditional labeling based on WB SAR should be derived from a conservative estimate of global LB/WB ratios. Published 2018.

    Fournier's gangrene is a surgical emergency that progresses rapidly and insidiously and results in high morbidity and mortality rates unless it is immediately diagnosed and managed. Here we analyze the outcomes of patients who were followed up and treated for Fournier's gangrene. We conducted a retrospective analysis of the medical data of 25 patients operated on for Fournier's gangrene between January 2010 and June 2015. The diagnosis of Fournier's gangrene was made by performing a physical examination. Patients who had genital, perineal, and perianal tenderness; induration; cyanosis; gangrene; and subcutaneous crepitation were considered as having Fournier's gangrene. Following resuscitation, aggressive surgical debridement was performed and vacuum-assisted closure (VAC) was conducted in addition to debridement in select patient. Repeat debridements were performed as requirement. This study included 25 patients. Fourteen patients (56%) were females and 11 (44%) were males. The mean age of the patients was 54.3 years (range: 27-82 years). The mean duration of hospital stay was 21.4 days; the mean number of debridements performed was 2.4. Thirteen patients (52%) had perianal abscesses, and 20 (80%) had diabetes mellitus. All patients underwent extensive debridement; 16 patients (64%) underwent VAC in addition to debridement. Patients undergoing VAC had significantly longer durations of hospital stay and a higher mean number of debridements performed (p=0.004 and p=0.048, respectively). An ostomy was made in one patient, and one patient died. In Fournier's gangrene, early diagnosis, effective resuscitation, aggressive debridement, and VAC application in suitable cases may reduce the morbidity and mortality rates and the need for an ostomy.

    Understanding summer low-flow variability and change in the mountainous West has important implications for water allocations downstream and for maintaining water availability for drinking water supply, reservoir storage, industrial, agricultural, and ecological needs. Wildfires and insect infestations are classical disturbance hydrology topics. It is unclear, however, what are their effects on streamflow and in particular low-flows, when vegetation disturbances are overlapping in time and combined with highly variable and potentially changing local climate. The purpose of this study, therefore, is to quantify changes in low-flows resulting from disturbance in headwater streams. Here we present a retrospective analysis based on: (1) 49-75 complete water years (wy) of daily streamflow data (USGS) for 14 high-elevation headwater watersheds with varying areas (60-1730 km2, 86-100% of watershed area >2000masl) and evergreen forest cover (15-82%), (2) 25-36 complete wy of daily snow-water equivalent accumulation (SWE) and precipitation data from Wyoming SNOTEL stations, (3) burned area boundaries for 20wy (MTBS project), (4) aerial surveys by R1, R2, R4 Forest Service Regions for 18wy (data on tree mortality). We quantify the change in various low-flow characteristics (e.g. post-snowmelt baseflow, Q90 and Q95, 3-,7-, 30- and 90-day annual minima etc.) while accounting for local inter- and multi-annual climate variability by using SWE accumulation data, as it integrates both temperature and precipitation changes. Our approach differs from typical before-after field-based investigation for paired watersheds, as it provides a synthesis over large temporal and spatial scales, resulting in spectrum of possible hydrologic responses due to varying disturbance severity. Quantifying the changes in low-flows and low-flow variability will improve our understanding and will facilitate water management and planning at local state-wide level.

    Despite advances in surgical techniques and products for stoma care, stoma-related complications are still common. A retrospective analysis was performed of the medical records of 462 consecutive patients (295 [63.9%] female, 167 [36.1 %] male, mean age 55.5 ± 15.1 years, mean body mass index [BMI] 25.1 ± 5.2) who had undergone stoma creation at the Gastroenterological Surgery Clinic of Turkiye Yuksek İhtisas Teaching and Research Hospital between January 2008 and December 2012 to examine the incidence of early (ie, within 30 days after surgery) stoma complications and identify potential risk factors. Variables abstracted included gender, age, and BMI; existence of malignant disease; comorbidities (diabetes mellitus, hypertension, coronary artery disease, chronic respiratory disease); use of neoadjuvant chemoradiotherapy; permanent or temporary stoma; type of stoma (loop/end stoma); stoma localization; and the use of preoperative marking of the stoma site. Data were entered and analyzed using statistical software. Descriptive statistics, chi-squared, and Mann-Whitney U tests were used to describe and analyze all variables, and logistic regression analysis was used to determine independent risk factors for stoma complications. Ostomy-related complications developed in 131 patients (28.4%) Of these, superficial mucocutaneous separation was the most frequent complication (90 patients, 19.5%), followed by stoma retraction (15 patients, 3.2%). In univariate analysis, malignant disease (P = .025), creation of a colostomy (P = .002), and left lower quadrant stoma location (P toma complication. Only stoma location was an independent risk factor for the development of a stoma complication (P = .044). The rate of stoma complications was not significantly different between patients who underwent nonemergent surgery (30% in patients preoperatively sited versus 28.4% not sited) and patients who underwent emergency surgery (27.1%). Early stoma complication rates were higher

    Script analysis as a test of executive functions is presumed sensitive to cognitive changes seen with increasing age. Two studies evaluated if gender differences exist in performance on scripts for familiar and unfamiliar tasks in groups of cognitively intact older adults. In Study 1, 26 older adults completed male and female stereotypical scripts. Results were not significant but a tendency was present, with genders making fewer impossible errors on the gender-typical script. Such an interaction was also noted in Study 2, which contrasted 50 older with 50 younger adults on three scripts, including a script with neutral familiarity. The pattern of significant interactions for errors suggested the need to use scripts that are based upon tasks that are equally familiar to both genders.

    Astronauts perform exercise throughout their missions to counter the health declines that occur as a result of long-term exposure to weightlessness. Although all astronauts perform exercise during their missions, the specific prescriptions, and thus the mechanical loading, differs among individuals. For example, inflight ground reaction force data indicate that subject-specific differences exist in foot forces created when exercising on the second-generation treadmill (T2) [1]. The current exercise devices allow astronauts to complete prescriptions at higher intensities, resulting in greater benefits with increased efficiency. Although physiological outcomes have improved, the specific factors related to the increased benefits are unknown. In-flight exercise hardware collect data that allows for exploratory analyses to determine if specific performance factors relate to physiological outcomes. These analyses are vital for understanding which components of exercise are most critical for optimal human health and performance. The relationship between exercise performance variables and physiological changes during flight has yet to be fully investigated. Identifying the critical performance variables that relate to improved physiological outcomes is vital for creating current and future exercise prescriptions to optimize astronaut health. The specific aims of this project are: 1) To quantify the exercise-related mechanical loading experienced by crewmembers on T2 and ARED during their mission on ISS; 2) To explore relationships between exercise loading variables, bone, and muscle health changes during the mission; 3) To determine if specific mechanical loading variables are more critical than others in protecting physiology; 4) To develop methodology for operational use in monitoring accumulated training loads during crew exercise programs. This retrospective analysis, which is currently in progress, is being conducted using data from astronauts that have flown long

    In a multicenter randomized phase II trial of gemcitabine (arm A), erlotinib (arm B), and gemcitabine and erlotinib (arm C), similar progression-free survival (PFS) and overall survival (OS) were observed in all arms. We performed an exploratory, blinded, retrospective analysis of plasma or serum samples collected as part of the trial to investigate the ability of VeriStrat (VS) to predict treatment outcomes. Ninety-eight patients were assessable, and the majority had stage IV disease (81%), adenocarcinoma histology (63%), reported current or previous tobacco use (84%), and 26% had a performance status (PS) of 2. In arm A, patients with VS Good (n = 20) compared with VS Poor status (n = 8) had similar PFS (hazard ratio [HR]: 1.21; p = 0.67) and OS (HR: 0.82; p = 0.64). In arm B, patients with VS Good (n = 26) compared with VS Poor (n = 12) had a statistically significantly superior PFS (HR: 0.33; p = 0.002) and OS (HR: 0.40; p = 0.014). In arm C, patients with VS Good (n = 17) compared with Poor (n = 1 5) had a superior PFS (HR: 0.42; p = 0.027) and a trend toward superior OS (HR: 0.48; p = 0.051). In the multivariate analysis for PFS, VS status was statistically significant (p = 0.011); for OS, VS status (p = 0.017) and PS (p = 0.005) were statistically significant. A statistically significant VS and treatment interaction (gemcitabine versus erlotinib) was observed for PFS and OS. Gemcitabine is the superior treatment for elderly patients with VS Poor status. First-line erlotinib for elderly patients with VS Good status may warrant further investigation.

    Full Text Available Background: Surgical treatment of adult lumbar spinal disorders is associated with a substantial risk of intraoperative and perioperative complications. There is no clearly defined medical literature on complication in lumbar spine surgery. Purpose of the study is to retrospectively evaluate intraoperative and perioperative complications who underwent various lumbar surgical procedures and to study the possible predisposing role of advanced age in increasing this rate. Materials and Methods: From 2007 to 2011 the number and type of complications were recorded and both univariate, (considering the patients′ age and a multivariate statistical analysis was conducted in order to establish a possible predisposing role. 133 were lumbar disc hernia treated with microdiscetomy, 88 were lumbar stenosis, treated in 36 cases with only decompression, 52 with decompression and instrumentation with a maximum of 2 levels. 26 patients showed a lumbar fracture treated with percutaneous or open screw fixation. 12 showed a scoliotic or kyphotic deformity treated with decompression, fusion and osteotomies with a maximum of 7.3 levels of fusion (range 5-14. 70 were spondylolisthesis treated with 1 or more level of fusion. In 34 cases a fusion till S1 was performed. Results: Of the 338 patients who underwent surgery, 55 showed one or more complications. Type of surgical treatment ( P = 0.004, open surgical approach (open P = 0.001 and operative time ( P = 0.001 increased the relative risk (RR of complication occurrence of 2.3, 3.8 and 5.1 respectively. Major complications are more often seen in complex surgical treatment for severe deformities, in revision surgery and in anterior approaches with an occurrence of 58.3%. Age greater than 65 years, despite an increased RR of perioperative complications (1.5, does not represent a predisposing risk factor to complications ( P = 0.006. Conclusion: Surgical decision-making and exclusion of patients is not justified only

    In the literature, little is known about the level and pattern of rugby injuries. Of the shoulder injuries reported, 51% of these are caused during a tackle, and 65% of all match injuries affected the shoulder. The study aims to describe a sport-specific unique intra-articular shoulder pathology of professional rugby players, who presented with persistent pain and dysfunction despite physiotherapeutic treatment and rest. This study is a retrospective analysis set at a university sports medicine clinic. Eighty-seven professional rugby players, referred by their professional medical team since they could no longer play, underwent shoulder arthroscopy between June 2001 and October 2007 due to persistent shoulder pain and dysfunction. All were full-time professional male rugby union and rugby league players. They all had failed conservative treatment for their complaint, and the diagnosis was unclear. Arthroscopic findings were used as a measure of main outcome. The primary mechanism of injury was reported as direct tackling (56%; n = 49) followed in succession by falling onto the arm (10%; n = 8). However, in 30% of the cases, no definite injury could be recalled. The main operative finding was that most patients exhibited multiple shoulder pathologies, with 75% of cases presenting with two or more pathologies. A superior labrum anterior to posterior (SLAP) lesion was evident at arthroscopy in 72 of the 87 cases (83%), while rotator cuff tears were evident in 43% of cases (n = 37). One-third of all cases had a Bankart tear (n = 29), despite none of them reporting previous dislocations, while other labral tears, excluding SLAP tears, to the inferior or posterior labrum were present in 34% (n = 30) of the cohort. Repeated tackling, which is clearly rugby specific, is most likely to be responsible for most of these shoulder injuries, which upon arthroscopic examination, showed signs of mixed pathology. We suggest that an early arthroscopic investigation is valuable in

    Age-related loss of muscle bulk and strength (sarcopenia) is often cited as a potential mechanism underlying age-related changes in swallowing. Our goal was to explore this phenomenon in the pharynx, specifically, by measuring pharyngeal wall thickness and pharyngeal lumen area in a sample of young versus older women. MRI scans of the neck were retrospectively reviewed from 60 women equally stratified into three age groups (20s, 60s, 70+). Four de-identified slices were extracted per scan for randomized, blinded analysis: one mid-sagittal and three axial slices were selected at the anterior inferior border of C2 and C3, and at the pit of the vallecula. Pixel-based measures of pharyngeal wall thickness and pharyngeal lumen area were completed using ImageJ and then converted to metric units. Measures of pharyngeal wall thickness and pharyngeal lumen area were compared between age groups with one-way ANOVAs using Sidak adjustments for post-hoc pairwise comparisons. A significant main effect for age was observed across all variables whereby pharyngeal wall thickness decreased and pharyngeal lumen area increased with advancing age. Pairwise comparisons revealed significant differences between 20s versus 70+ for all variables and 20s versus 60s for all variables except those measured at C2. Effect sizes ranged from 0.54 to 1.34. Consistent with existing sacropenia literature, the pharyngeal muscles appear to atrophy with age and consequently, the size of the pharyngeal lumen increases.

    To evaluate the discriminative value of conventional magnetic resonance imaging between benign and malignant palatal tumors. Conventional magnetic resonance imaging features of 130 patients with palatal tumors confirmed by histopathologic examination were retrospectively reviewed. Clinical data and imaging findings were assessed between benign and malignant tumors and between benign and low-grade malignant salivary gland tumors. The variables that were significant in differentiating benign from malignant lesions were further identified using logistic regression analysis. Moreover, imaging features of each common palatal histologic entity were statistically analyzed with the rest of the tumors to define their typical imaging features. Older age, partially defined and ill-defined margins, and absence of a capsule were highly suggestive of malignant palatal tumors, especially ill-defined margins (β = 6.400). The precision in determining malignant palatal tumors achieved a sensitivity of 92.8% and a specificity of 85.6%. In addition, irregular shape, ill-defined margins, lack of a capsule, perineural spread, and invasion of surrounding structures were more often associated with low-grade malignant salivary gland tumors. Conventional magnetic resonance imaging is useful for differentiating benign from malignant palatal tumors as well as benign salivary gland tumors from low-grade salivary gland malignancies.

    2017-04-01

    Accurate measurement of oculomotor function using videonystagmography (VNG) is imperative for diagnosis and management of patients with reported dizziness. The oculomotor evaluation during VNG utilizes video-oculography providing valuable information regarding the central structures and pathways that control eye movements. Artifact may have an effect on the overall validity and reliability of VNG oculomotor tracings and can result from patient and/or recording errors. It is postulated that artifact could occur more frequently in the pediatric population due to both patient and equipment factors. The purpose of this study was to systematically evaluate the occurrence and impact of artifact on saccades, smooth pursuit, and optokinetic (OPK) testing in normal pediatric and adult subjects using commercially available clinical VNG equipment and standard clinical protocols for oculomotor testing. The present study utilized a retrospective analysis of a repeated measures design. Oculomotor results from a total of 62 participants were analyzed. Portions of these data have been presented in a previous research study. Group 1 consisted of twenty-nine 4- to 6-yr-olds with an average age of 4.86 (SD = 0.88) yr. Group 2 consisted of thirty-three 22- to 44-yr-olds with an average age of 25.2 (SD = 5.34) yr. Raw oculomotor recordings were analyzed "offline" by a single masked, trained investigator. Each tracing was evaluated for instances of artifact including eye blinks, eye closure, eyes moving in opposite direction of the target, eye tracking software problems, and overall poor morphology. The number of instances of artifact were noted and recorded for each participant in both groups. Individual eye movements not affected by artifact were included for final analysis. Artifact rejection techniques were also compared. The results indicated increased artifact for the pediatric group for saccade and smooth pursuit testing. Additionally, a significant decrease in instances of

    To explore the general characteristics of medical negligence in surgery in order to provide the reference for forensic practices. One hundred and twelve cases of medical negligence in surgical department were retrospectively analyzed in Fada Institute of Forensic Medicine and Science from 2008 to 2010. The common types of medical negligence cases in the surgery were improper operation procedure (28.57%), failure of consent (26.79%), and inadequate monitoring (22.32%). The results of complications included disability or functional impairment (61.61%), death (31.25%) and transient impairment with no obvious adverse reactions (7.14%). The most common roles played by the medical negligence cases were minor role (26.79%), equal role (19.64%), and slight role (14.29%). Significant attention should be paid to the operation procedure, consent, and monitoring. It should be cautious to not make assessment on involvement degree of medical negligence.

    Aim . Headache is one of the most common diseases associated with Temporomandibular Disorders (TMDs). The aim of this study was to evaluate, retrospectively, if headache influences TMD's symptoms. Material and Methods . A total sample of 1198 consecutive TMD patients was selected. After a neurological examination, a diagnosis of headache, according to the latest edition of the International Classification of Headache Disorders, was performed in 625 subjects. Patients were divided into two groups based on presence/absence of headache: Group with Headache (GwH) and Group without Headache (GwoH). Descriptive statistics and Chi-square index were performed. Results . Sociodemographic (gender, marital status, and occupation) and functional factors, occlusion (occlusal and skeletal classes, dental formula, and occlusal abnormalities), and familiar pain did not show a statistically significant correlation in either group. Intensity and frequency of neck pain, arthralgia of TMJ, and myalgia showed higher correlation values in GwH. Conclusion . This study is consistent with previous literature in showing a close relationship between headache and TMD. All data underlines that headache makes pain parameters more intense and frequent. Therefore, an early and multidisciplinary treatment of TMDs should be performed in order to avoid the overlay of painful events that could result in pain chronicity.

    Paracoccidioidomycosis (PCM) is a rare fungal infection in the world, but endemic and acquired exclusively in Latin America, with the highest prevalence in South America and Brazil, particularly. Changes in oral cavity are common and constitute the first clinical manifestation in many patients. The aim of this study was to describe the prevalence of oral PCM and analyse the profile of the disease and patients. Retrospective research, consisting of information present in the medical records in the period 1998-2015, whose histopathological diagnosis was oral PCM. Fifty-five oral PCM cases were confirmed. Of these patients, 90.9% were males and 9.1% were females. The average age was 49.66 years and the most reported occupation was rural workers. The painful symptomatology was present in 61.82% of patients. Erythematous lesions were predominant in 73% of them. In single lesions (22 cases), the most common locations were jugal mucosa and tongue. In multiple involvement (30 cases), the most affected regions were lips, jugal mucosa and alveolar ridge. Epidemiology of PCM, was similar to several other studies, especially in Brazil. This is the most important fungal infection in Latin America and the recognition of oral lesions is extremely important, as is often the first and in many cases the only manifestation of the disease. © 2017 Blackwell Verlag GmbH.

    Objective: This study aimed at documenting the spectrum of clinico pathological variations in hepatocellular carcinoma (HCC). Design: It was a retrospective study. Place and duration of Study: This study was conducted at the Institute of Nuclear Medicine and Oncology (INMOL) Hospital, Lahore from March 1997 to December 2000. Patients and Methods: The profiles of 118 patients with a biopsy proven hepatocellular carcinoma were analyzed in this period. The data collected was age, sex, clinical presentation and laboratory investigations including liver function tests, alpha fetoprotein and hepatitis profile. Results: Weight loss, jaundice and right upper quadrant abdominal pain were the main presenting symptoms. Out of 118 patients, alpha fetoprotein values were raised in 63(53.38%) patients 106 (89.83%) patients were found to have or have had HBV infections, and 92 (77.96%) patients were anti-HCV positive. Eighty-three (70.33%) patients were cirrhotic. History of alcohol abuse was bound in three patients. Conclusion: The common association of HCC with cirrhosis and hepatitis B and C suggests that vaccination against HBV on nationwide basis can decrease prevalence of this malignancy. There is a need to generate public awareness regarding the transmission of these viruses. Early diagnosis and intervention is also important to the successful management of HCC. (author)

    Full Text Available Aim. Headache is one of the most common diseases associated with Temporomandibular Disorders (TMDs. The aim of this study was to evaluate, retrospectively, if headache influences TMD’s symptoms. Material and Methods. A total sample of 1198 consecutive TMD patients was selected. After a neurological examination, a diagnosis of headache, according to the latest edition of the International Classification of Headache Disorders, was performed in 625 subjects. Patients were divided into two groups based on presence/absence of headache: Group with Headache (GwH and Group without Headache (GwoH. Descriptive statistics and Chi-square index were performed. Results. Sociodemographic (gender, marital status, and occupation and functional factors, occlusion (occlusal and skeletal classes, dental formula, and occlusal abnormalities, and familiar pain did not show a statistically significant correlation in either group. Intensity and frequency of neck pain, arthralgia of TMJ, and myalgia showed higher correlation values in GwH. Conclusion. This study is consistent with previous literature in showing a close relationship between headache and TMD. All data underlines that headache makes pain parameters more intense and frequent. Therefore, an early and multidisciplinary treatment of TMDs should be performed in order to avoid the overlay of painful events that could result in pain chronicity.

    The objective of this study was to retrospectively analyze the incidence of the concurrent existence of temporomandibular disorders (TMD) and headaches. Forty patients (36 female, 4 male, mean age: 29.9±9.6 years) clinically diagnosed with TMD were screened. Patient records were analyzed regarding: range of mouth opening, temporomandibular joint (TMJ) noises, pain on palpation of the TMJ and masticatory muscles and neck and upper back muscles, and magnetic resonance imaging of the TMJ. According to patient records, a total of 40 (66.6%) patients were diagnosed with TMD among 60 patients with headache. Thirty-two (53%) patients had TMJ internal derangement (ID), 8 (13%) patients had only myofascial pain dysfunction (MPD) and 25 (41.6%) patients had concurrent TMJ ID/MPD. There were statistically significant relationships between the number of tender masseter muscles and MPD patients (p=0.04) and between the number of tender medial pterygoid muscles and patients with reducing disc displacement (RDD) (p=0.03). The TMJ and associated orofacial structures should be considered as possible triggering or perpetuating factors for headaches, especially tension-type. There might be a significant connection between TMD and headache. However, most medical and dental practitioners are unaware of this relationship. Therefore, a careful evaluation of the TMJ and associated orofacial structures is required for a correct interpretation of the craniofacial pain in headache patients, and these patients should be managed with a multidisciplinary approach.

    Full Text Available Abstract Background Estimates of baseline incidence of childhood intussusception could help safety monitoring after the introduction of rotavirus vaccines. We studied the incidence of intussusception in Uzbekistan, a GAVI-fund eligible state in Central Asia. Methods We retrospectively reviewed intussusception cases in children Results Over a 5-year study period, 67 confirmed cases were identified, of which 67% were boys. The median age was 12 months, and no seasonal trend in the distribution of cases was observed. The diagnostic methods used included abdominal radiography (87% and ultrasonography (57%. Intussusception reduction by air enema was successful in 33 (49% patients and 34 (50% cases underwent surgery. A total of 4 deaths occurred, including 3 deaths in infants aged 0-6 months. The median length of hospital stay was 7.3 (range 0-37 days. The incidence of intussusception is estimated at 23 (95% CI 13.6-32.4 cases per 100,000 child-years, corresponding to approximately 237 cases annually. Conclusions This is the first study to estimate the incidence of childhood intussusception prior to the introduction of the rotavirus vaccination in Uzbekistan. A prospective surveillance system using a standardized case definition is needed in order to better examine the occurrence of intussusception in developing countries.

    Full Text Available Abstract The Semantic Verbal Fluency (SVF test entails the generation of words from a given category within a pre-set time of 60 seconds. Objectives: To verify whether socio-demographic and clinical data of individuals with dementia correlate with the performance on the SVF test and to ascertain whether differences among the criteria of number of answers, clusters and data spread over the intervals, predict clinical results. Methods: This was a retrospective study of 49 charts of demented patients classified according to the Clinical Dementia Rating (CDR scale. We correlated education, age and gender, as well as CDR and Mini-Mental State Exam (MMSE scores with the number of answers, clustering and switching distributed over four 15-second intervals on the SVF test. Results: The correlation between number of answers and quartiles was weak (r=0.407, p=0.004; r=0.484, p<0.001 but correlation between the number of clusters and responses was strong (r=0.883, p<0.001. The number of items on the SVF was statistically significant with MMSE score (p=0.01 and there was a tendency for significance on the CDR (p=0.06. The results indicated little activity regarding what we propose to call cluster recalling in the two groups. Discussion: The SVF test, using number of items generated, was found to be more effective than classic screening tests in terms of speed and ease of application in patients with CDR 2 and 3.

    The purpose of this study was to analyze the incidence, clinical presentation, diagnosis, and treatment of false traumatic aneurysms and arteriovenous fistulas as well as the outcomes of the patients. A retrospective, 16-year survey has been conducted regarding the cases of patients who underwent surgery for false traumatic aneurysms (FTA) of arteries and traumatic arteriovenous fistulas (TAVF). Patients with iatrogenic AV fistulas and iatrogenic false aneurysms were excluded from the study. There were 36 patients with TAVF and 47 with FTA. In all, 73 (87.95%) were male, and 10 (12.05%) were female, with an average age of 36.93 years (13-82 years). In 25 (29.76%) cases TAVF and FTA appeared combat-related, and 59 (70.24%) were in noncombatants. The average of all intervals between the injury and surgery was 919. 8 days (1 day to 41 years) for FTA and 396.6 days (1 day to 9 years) for TAVF. Most of the patients in both groups were surgically treated during the first 30 days after injury. One patient died on the fourth postoperative day. There were two early complications. The early patency rate was 83.34%, and limb salvage was 100%. There were no recurrent AV fistulas that required additional operations. Because of their history of severe complications, FTA and TAV fistulas require prompt treatment. The treatment is simpler if there is only a short interval between the injury and the operation. Surgical endovascular repair is mostly indicated.

    Summary Background Data on imported malaria in pregnant women are scarce. Method A retrospective, descriptive study of pooled data on imported malaria in pregnancy was done, using data from 1977 to 2014 from 8 different collaborators in Europe, the United States and Japan. Most cases were from the period 1991–2014. National malaria reference centresas well as specialists on this topic were asked to search their archives for cases of imported malaria in pregnancy. A total of 632 cases were collated, providing information on Plasmodium species, region of acquisition, nationality, country of residence, reason for travel, age, gestational age, prophylactic measures and treatment used, as well as on complications and outcomes in mother and child. Results Datasets from some sources were incomplete. The predominant Plasmodium species was P. falciparum in 72% of cases. Among the 543 cases where information on the use of chemoprophylaxis was known, 471 (74.5%) did not use chemoprophylaxis or used incorrect or incomplete chemoprophylaxis. The main reason for travelling was “visiting friends and relatives” VFR (48.6%) and overall, most cases of malaria were imported from West Africa (85.9%). Severe anaemia was the most frequent complication in the mother. Data on offspring outcome was limited, but spontaneous abortion was a frequently reported foetal outcome (n = 14). A total of 50 different variants of malaria treatment regimens were reported. Conclusion Imported cases of malaria in pregnancy are mainly P. falciparum acquired in sub-Saharan Africa. Malaria prevention and treatment in pregnant travellers is a challenge for travel medicine due to few data on medication safety and maternal and foetal outcomes. International, collaborative efforts are needed to capture standardized data on imported malaria cases in pregnant women. PMID:26227740

    Full Text Available Aim: Osteosarcomas must be managed by a team which includes pathologists, radiologists, surgeons, radiation therapists, and medical oncologists. Treatment modalities and demographic charasteristics of osteosarcomas were analysed in this study. Material and Method: Primary osteosarcomas treated between 1999-2010 in Cukurova University Medical Faculty Department of Medical Oncology were analysed retrospectively. Results: Of the total 119 patients, 74% were male and 26% female. The median age was 19. The median follow up time was 37 months. The most frequently seen sarcomas were osteoblastic at 82.4%. Localization of the disease was found to be 55% in the lower extremity, 14.1% in the upper extremity, 13% in the head-neck, 6.6% in the thoracic area, and 4.1 % in the pelvic region. Some 6.41% were local stage, 25.64% locally advanced, 15.8% metastatic, and 14.10% were diagnosed with nuks disease. Chemotherapy was administered in 77 of 119 patients. Patients received different treatments: 23.1% were treated with preoperative chemotherapy, 16.67% postoperative, 9.52% palliative, 33.33% preoperative postoperative, 2.38% postoperative palliative, 9.52% preoperative postoperative palliative chemotherapy, and 4.76% of the patients did not receive chemotherapy. Both radical and conservative surgery was performed. The most common metastatic site was the lungs. The overall length of survival was 65 months (95%CI 30-59. The survival rates did not vary between the groups of preoperative, postoperative, preoperative postoperative chemotherapy and other groups (respectively 23 versus 36 versus 28 versus 44 months (p=0.8. No differences were evident for radiotherapy (p=0.06. Discussion: Osteosarcomas can be treated successfully with surgery, chemotherapy, and radiotherapy. There was no cumulative survival difference in results based on the types of chemotherapy used in this study. These results show the importance of a multimodality treatment approach including

    Primary intracranial germinomas (PIGs) are rare malignant brain tumors that represent approximately 0.2% to 1.7% of all primary intracranial tumors. PIGs have infrequent, but there is a possibility of spinal cord metastases. In this study, clinical outcomes of five consecutive PIGs have been presented. Medical records were retrospectively reviewed in 1,849 cases of intracranial tumors who underwent surgery between the years 2005 and 2015 and cases confirmed as germinoma histopathologically were included in this study. Five cases of PIGs were detected in two female (40%) and 3 male (60%) patients. The mean age was 15.2±5.6 (8-23) years. The mean follow-up period was 52.3±56.4 (9-135) months. The most common complaint was headache (60%), followed by nausea±vomiting (40%). Four cases (80%) affected the suprasellar region while the fifth patient"s tumor was localized in the pineal region. The duration between the initial symptom and time of surgical intervention ranged between 15 days and 2 months. Twelve months after the first operation, one patient presented with drop seeding metastasis. Four-year survival (with exception of the case that died as a early surgical complication) was 100%. Gross total resection (GTR) was achieved in one patient. Surgical mortality rate was 20%. PIGs" morbidity rate was 60%. PIG is a mostly malignant tumor that generally affects the pediatric age group. They are radiosensitive tumors. Subtotal or near-total resection using stereotactic guide or direct surgery to confirm the histopathological diagnosis followed by chemotherapy and whole brain or in some cases craniospinal radiotherapy rather than GTR is therefore the treatment of choice.

    The aim of this retrospective study was to determine the clinical and the radiographic outcomes of dental implants placed in elderly people older than 65 years. In total, 902 implants in 346 patients (age: 65-89 years) were followed up for 2-17 years following the implant surgery. The survival rate of these implants was recorded and analyzed. Changes in marginal bone levels were also analyzed in serial radiographs, and Cox regression analysis for implant loss was performed. The survival rates were 95.39% and 99.98% in the implant- and patient-based analyses, respectively (involving a total of 29 implant failures), and the marginal bone loss at the implants was 0.17 ± 0.71 mm (mean ± SD). The number of failures was greatest in patients aged 65-69 years. The Cox regression with shared frailty analysis showed that implant loss was significantly greater in those aged 65-69 years than in those aged 70-74 years (P implant systems. Within the limitations of this retrospective study, it was concluded that implant therapy can be successfully provided to elderly patients and that age alone does not seem to affect the implant survival rate. © 2016 John Wiley & Sons A/S.

    Full text: Radioiodine is a safe form of treatment for all patients with primary hyperthyroidism. The thyroid's unique capacity to store iodine (thus also radioiodine) makes it a natural target for radioiodine therapy. We retrospectively analyzed the outcome of radioiodine therapy in a cohort of 151 patients of primary hyperthyroidism treated on an outpatient basis in our institute from January 2001 to November 2006. Of these 151 patients, 113 (38 male, 75 female; age range: 17- 65 years) were of Graves' disease. The median duration of symptoms in these patients was 4 years. (Range: 3 months to 20 years). Diagnosis was established on basis of clinical, biochemical and scintigraphic features. All the patients were treated medically with Neomercazole (Carbimazole) for varying durations (median 3.5 years). The dose range varied from 5 to 80 mg per day (median 20 mg per day). Clinical assessment of thyroid size revealed 39 patients with grade 0, 14 with grade 1, 30 with grade 2, and 30 with grade 3 goiters. Pre-therapy radioactive iodine uptake was done in 28 patients, which showed median values of 50 % at 4 hrs, 57.45 % at 24 hrs, and 56.2 % at 48 hrs respectively. These patients were treated empirically with I-131 in a dose range of 5 to 15 mCi, depending upon the clinical presentation and the RAIU values. Remission of symptoms with a single dose therapy was noticed in 68 patients. Of the 83 patients, 15 became hypothyroid within 3 months. These patients were on Neomercazole for a varying period of 2 to 20 years, at a dose range of 10 to 80 mg per day. 14 patients achieved remission after 2 doses with a cumulative RAI dose in the range of 10 to 19 mCi, at a median period of 7 to 24 months. Eight patients still showed hyperthyroid activity even after a second dose and are on follow-up. Seven patients achieved remission with a cumulative dose range of 17 to 35 mCi at a median duration of 10 months. One patient of Graves' disease who took Neomercazole for 10 years, at

    Full Text Available Spontaneous pneumothorax (SP is relatively common in clinical practice and occurs more frequently in young, tall thin men, and in smokers. However, simultaneous bilateral spontaneous pneumothorax (SBSP is a rare clinical condition that often presents with significant respiratory distress. It is often dangerous; therefore, the chest drain should be inserted immediately. In this study, simultaneus bilateral spontaneus pneumothoraces cases were divided into two groups and retrospectively evaluated according to age, sex, diagnostic methods, treatments, and results. Material and Methods :Between January 2006 and May 2009, 11 patients with SBSP were enrolled into our study. Age, gender, underlying lung disease, smoking history, symptoms, diagnosis, treatment type, surgical indication, morbidity, recurrence, mortality, duration of chest tube and postoperative hospital stay of the patients were reviewed. Arterial blood gas values (before and after intervention in patiens with primary and secondary spontaneous pneumothorax were evaluated. Results; 7 patients (63.63 % were male and 4 patients (36.37 % were female and their mean age was 34,5±6.81 years. There were 4 (36.37% primary SP and 4 (36.37% secondary SP patients. Chronic obstructive pulmonary disease (COPD was the most common cause in secondary SP patients. In two (18.18% patients recurrency were observed. Eight (72.72% patients had smoking history. The most common symptom in both groups was dyspnea. All patients had immediate bilateral chest tubes on admission. We treated these patients with chest drain insertion, VATS (Video-Assisted Thoracoscopic Surgery, axillary thoracotomy, and chemical pleurodesis. Postoperative morbidity was detected in 3 (27.27% patients (prolonged air leak in 1 case, empyema in 1 case and pneumonia in 1 case. No mortality was observed in alll cases. Recurrence developed in 3 (27.27% patients in this series. Conclusions: An urgent and effective treatment requires in the

    With the Meta-analysis method, the clinical efficacy of acupuncture and other regular methods for aphasia was evaluated, and the acupoints selection for aphasia was explored. The acupuncture literature of clinical randomized control trials for aphasia published in CNKI, WANFANG, VIP and CBM database was searched; the statistical analysis of clinical efficacy of acupuncture and other regular methods for aphasia was performed by using software Revman 5. 2 provided by Cochrane library. A file of Microsoft Excel was established to perform the analysis of acupoints selection based on frequency analysis method, so as to summarize the characteristics and rules. Totally 385 articles were searched, and 37 articles those met the inclusive criteria was included, involving 1,260 patients in the acupuncture group and 1 238 patients in the control group. The Meta-analysis results showed OR = 3.82, 95% Cl [3.01, 4.85]; rhombus was located on the right side and the funnel plot was nearly symmetry, indicating the treatment effect of the acupuncture group for aphasia was superior to the control group (Z = 11.04, P aphasia is superior to that of speech rehabilitation training and medication treatment alone. The clinical treatment for aphasia focuses on its local effect; the main acupoints are in the head and face, and the meridians are governor vessel, extra channels and conception vessel.

    This research explored the relationship between the stages of frailty and risk for hospitalization in older adults and evaluated the risk for hospitalization among the elderly in relation to various frailty assessment indexes. A systematic literature review and meta-analysis were carried out. A total of 32,998 older people, 8,666 of whom were hospitalized, were included in this study. Two of the researchers independently collected and reviewed the literature. The key search terms used were "frailty" or "frail," "hospitalization," and "older people" or "older" or "geriatric" or "senior." Data were recorded from January 2001 to July 2016. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were adopted for quality assessment. A systematic search was carried out using Embase and Scopus to analyze the collected literature. A meta-analysis was conducted on eight studies that discussed the relationship between frailty and hospitalization risk in older adults 65 years of age or older. The results showed that frail older people exhibited the highest risk for hospitalization, following by prefrail and robust older people. Next, different frailty assessment indicators were used to predict the risk for hospitalization among older people. All of these indexes also showed that older persons with frailty had the highest risk for hospitalization, followed by prefrail older people. Frailty is a vital issue in geriatric care and is a crucial factor in the hospitalization of older people. Frail older people were at the highest risk for hospitalization, following by prefrail and robust older people. Assessing frailty as early as possible can reduce the hospitalization risk among older people. Professional nursing staff should use frailty indicators in a timely fashion to assess the status of frailty in older people and should effectively develop frailty prevention strategies to decrease the risk for hospitalization and to enhance quality of life

    A systematic review and meta-analysis of memory training research was conducted to characterize the effect of memory strategies on memory performance among cognitively intact, community-dwelling older adults, and to identify characteristics of individuals and of programs associated with improved memory. The review identified 402 publications, of which 35 studies met criteria for inclusion. The overall effect size estimate, representing the mean standardized difference in pre-post change between memory-trained and control groups, was 0.31 standard deviations (SD; 95% confidence interval (CI): 0.22, 0.39). The pre-post training effect for memory-trained interventions was 0.43 SD (95% CI: 0.29, 0.57) and the practice effect for control groups was 0.06 SD (95% CI: 0.05, 0.16). Among 10 distinct memory strategies identified in studies, meta-analytic methods revealed that training multiple strategies was associated with larger training gains (p=0.04), although this association did not reach statistical significance after adjusting for multiple comparisons. Treatment gains among memory-trained individuals were not better after training in any particular strategy, or by the average age of participants, session length, or type of control condition. These findings can inform the design of future memory training programs for older adults.

    Positive outcomes from intensive therapy for individuals with aphasia have been reported in the literature. Little is known about the characteristics of individuals who attend intensive comprehensive aphasia programs (ICAPs) and what factors may predict who makes clinically significant changes when attending such programs. Demographic data on participants from 6 ICAPs showed that individuals who attend these programs spanned the entire age range (from adolescence to late adulthood), but they generally tended to be middle-aged and predominantly male. Analysis of outcome data from 2 of these ICAPs found that age and gender were not significant predictors of improved outcome on measures of language ability or functional communication. However, time post onset was related to clinical improvement in functional communication as measured by the Communication Activities of Daily Living, second edition (CADL-2). In addition, for one sample, initial severity of aphasia was related to outcome on the Western Aphasia Battery-Revised, such that individuals with more severe aphasia tended to show greater recovery compared to those with mild aphasia. Initial severity of aphasia also was highly correlated with changes in CADL-2 scores. These results suggest that adults of all ages with aphasia in either the acute or chronic phase of recovery can continue to show positive improvements in language ability and functional communication with intensive treatment.

    Some old persons at risk do develop, but others, at comparable risk, do not develop high-grade pressure sores. To evaluate potentially different risk factors, we performed a post mortem case-control study in old persons who developed high-grade pressure sores within six months until 14 days before death. Consecutive cases with pressure sores grade >/=3 and potential controls at comparably high risk for pressure sores were examined before cremation. After written informed consent had been obtained by the next relatives, all available nursing and medical records of the deceased were thoroughly evaluated. Cases and controls were matched according to age, gender, immobility, and cachexia.A total of 100 cases with 71 pressure sores grade 3 and 29 pressure sores grade 4 were compared to 100 controls with 27 pressure sores grade pressure sores in frail older high-risk persons. Sedative drug effects and impaired patient compliance with preventive and therapeutic measures may also be associated with the development of high-grade pressure sores in old persons at high risk.

    Lung abscess is a collection of necrotic and suppurated tissue located at the pulmonary parenchyma. Empyema is defined as the presence of pus in the pleural space. To study the clinical and microbiological characteristics, treatment and prognosis of patients with lung abscess and/or empyema admitted to an Internal Medicine ward. A retrospective analysis of medical records was performed, including all patients admitted to an Internal Medicine ward for lung abscess or empyema, between 2000 and 2008. Thirty patients were included (22 males/ eight females), accounting for 0.18% of all patients admitted in this ward in the same period. Three patients had pulmonary abscess, 18 empyema, and nine both diseases. The average age was 68.5 years (31 to 90). The most frequent complaints were dyspnoea (90%), fever (73.3%), cough (66.7%), weight loss (60%) and chest pain (53.3%). The most frequent associated disorders were stroke associated disability (46.7%), heart failure (43.3%) and arterial hypertension (33.3%). Thoracentesis was performed in all patients with empyema. In one patient with lung abscess an anaerobic microorganism was identified. In patients with empyema, cultures were positive in 61.1% of cases, with a slight predominance of methicillin-resistant Staphylococcus aureus (27.3%) and Prevotella intermedia (18.2%). In patients with both abscess and empyema, cultures of the abscess were positive in 44.4% and of the pleural fluid in 33.3%, with no predominant microorganism. Empiric antimicrobial therapy was started in all patients and later adapted to the antibiotic sensitivity test results. Surgery was performed in three patients. Seven patients (23.3%) died during admission. The average age of the patients who died was 81.3 years and of those who survived was 64.5 years. Lung abscess and empyema are infrequent diseases in an Internal Medicine ward, affect mostly males and have unspecific clinical manifestations. The chest X-ray, computed tomography (CT) and

    Despite the traditional focus being adverse drug reactions (ADRs), pharmacovigilance centres have recently been identified as a potentially rich and important source of medication error data. To identify medication errors in the New Zealand Pharmacovigilance database (Centre for Adverse Reactions Monitoring [CARM]), and to describe the frequency and characteristics of these events. A retrospective analysis of the CARM pharmacovigilance database operated by the New Zealand Pharmacovigilance Centre was undertaken for the year 1 January-31 December 2007. All reports, excluding those relating to vaccines, clinical trials and pharmaceutical company reports, underwent a preventability assessment using predetermined criteria. Those events deemed preventable were subsequently classified to identify the degree of patient harm, type of error, stage of medication use process where the error occurred and origin of the error. A total of 1412 reports met the inclusion criteria and were reviewed, of which 4.3% (61/1412) were deemed preventable. Not all errors resulted in patient harm: 29.5% (18/61) were 'no harm' errors but 65.5% (40/61) of errors were deemed to have been associated with some degree of patient harm (preventable adverse drug events [ADEs]). For 5.0% (3/61) of events, the degree of patient harm was unable to be determined as the patient outcome was unknown. The majority of preventable ADEs (62.5% [25/40]) occurred in adults aged 65 years and older. The medication classes most involved in preventable ADEs were antibacterials for systemic use and anti-inflammatory agents, with gastrointestinal and respiratory system disorders the most common adverse events reported. For both preventable ADEs and 'no harm' events, most errors were incorrect dose and drug therapy monitoring problems consisting of failures in detection of significant drug interactions, past allergies or lack of necessary clinical monitoring. Preventable events were mostly related to the prescribing and

    Full Text Available Background: Elevations in Homocyteine (Hcys levels in the blood have been correlated with increased risk for coronary heart disease and stroke, loss of cognition and memory, and other chronic medical conditions. Objective: A retrospective study was initiated to determine if Hcys levels and other blood markers were altered in subjects taking an oral functional food supplement containing a mixture of phosphoglycolipids (NT Factor® and vitamins. Methods: Thirty-five patients (28 females, 7 males, Av. Age=60.7±9.6 years who had used the functional food Advanced Physician’s FormulaTM with NTFactor® in tablet form each day were enrolled in a retrospective study on blood chemistry. This retrospective study followed a prospective study on the use of the same supplement to reduce fatigue in patients with chronic fatigue. Participants were patients with chronic fatigue syndrome (myalgic encephalomyelitis or other fatiguing illnesses. Subjects had blood drawn over a 6-month period, and routine blood testing was performed. In this laboratory study the results were analyzed for differences, and statistical analyses were performed. Results: All participants responded in the study and showed an average reduction of 31.8% in Hcys levels (from 10.85±0.42 to 7.40±0.42 µmol/L; t-test, p<0.001; Wilcoxon, p<0.001. Women responded better than men: women (from 11.06±0.50 to 8.67±0.82 µmol/L, 34.4% reduction, t-test, p< 0.001; Wilcoxon, p<0.001 versus men (from 10.80±0.51 to 7.01±0.47 µmol/L, 21.6% reduction, t-test, p< 0.0862.

    Full Text Available The detection of a low serum phosphate level is not unusual in an Emergency Department, especially in clinical conditions linked to hyperventilation and subsequent respiratory alkalosis, asthma, sepsis, severe pain, anxiety. Symptoms of hypophosphatemia are typically not specific when the imbalance is not particularly severe, but if hyphophosphatemia does not resolve rhabdomyolisis, hemolysis, decreased tissue oxygenation and respiratory failure can be observed. Only recently some authors have pointed out that the level of serum phosphate in patient with anxiety and panic disorders can give information on the severity of the attacks as well on the clinical course of the disease. In a retrospective analysis on 599 case of hypophosphatemia observed in our ED, the percentage of case of panic disorders was particularly high among patients with lower phosphatemia. Therefore, we decided to examine this aspect closely, assessing if the determination of serum phosphate could be useful in the management of panic attacks at first approach in emergency room. Our observation are consistent with the statement that hypophosphatemia is one of the main clinical aspect of panic attack, and strongly support the hypothesis that hypophosphatemia correlates with the most severe symptoms of panic attack and should be itself considered as one of the most important aspect of this syndrome. Serum phosphate levels appear to mirror its clinical course, and can be used in the clinical setting of an Emergency Department, for the confirmation of a diagnosis of anxiety-panic disorder and as marker of the response to therapy

    The effect of chronic benzodiazepine use on blood pressure has not been documented. We aimed to evaluate whether regular benzodiazepine use can be associated to the results of ambulatory blood pressure monitoring (ABPM). A retrospective analysis of the ABPM database between 2009 and 2015 was performed. The study groups were divided according to benzodiazepine treatment at least 3 months before ABPM. Generalized estimating equation (GEE) model analysis was conducted to estimate the association between benzodiazepine treatment and ABPM test measurements. Multivariable COX regression survival analysis model for mortality and cardiovascular (CV) events was performed. A total of 4,938 ABPM studies were included in final analysis, 670 ABPMs of benzodiazepine-treated patients, and 4,268 of untreated patients. The benzodiazepine-treated group was significantly older, with a predominance of female patients, comprised more diabetic patients and consumed more antihypertensive medications. Adjustment for age, gender, diabetes mellitus, and number of antihypertensive medications, showed an association between benzodiazepine treatment and significantly lower ABPM measurements. When the analysis was split into those ≥60 years old and the other ABPM measurements only among ≥60 years old. Multivariable Cox regression survival analysis showed that regular benzodiazepine consumption was not associated with increased mortality or CV events (mean follow-up period of 42.4 ± 19.8 and 42.1 ± 20.0 months, respectively). Long-term use of benzodiazepines by ≥60 years old was independently associated with lower diastolic and systolic blood pressure in all parameters of ABPM, but not among younger patients.

    Thermoluminescence (TL), Optically-Stimulated Luminescence (OSL) and Infrared-Stimulated Luminescence (IRSL) emitted from a set of 19 salt (NaCl) samples were studied for potential application to retrospective dosimetry. TL emission spectra revealed intense TL emissions from most samples, centred on 590 nm; UV and blue emissions were also found. Significant thermally-induced sensitivity changes were observed and TL, OSL and IRSL growth curves were measured. Pulse anneal analysis was performed, as was quantitative imaging of the TL, OSL and IRSL to assess sample heterogeneity. Kinetic analysis found lifetimes at 20 °C of the 200 °C and 240 °C TL peaks to be 0.6 ka and 4 ka respectively; sufficient for application to retrospective dosimetry.

    Pecina, Jennifer L; North, Frederick

    2017-06-01

    Introduction Under certain circumstances, e-consultations can substitute for a face-to-face consultation. A basic requirement for a successful e-consultation is that the e-consultant has access to important medical history and exam findings along with laboratory and imaging results. Knowing just what information the specialist needs to complete an e-consultation is a major challenge. This paper examines differences between specialties in their need for past information from laboratory, imaging and clinical notes. Methods This is a retrospective study of patients who had an internal e-consultation performed at an academic medical centre. We reviewed a random sample of e-consultations that occurred in the first half of 2013 for the indication for the e-consultation and whether the e-consultant reviewed data in the medical record that was older than one year to perform the e-consultation. Results Out of 3008 total e-consultations we reviewed 360 (12%) randomly selected e-consultations from 12 specialties. Questions on management (35.8%), image results (27.2%) and laboratory results (25%) were the three most common indications for e-consultation. E-consultants reviewed medical records in existence more than one year prior to the e-consultation 146 (40.6%) of the time with e-consultants in the specialties of endocrinology, haematology and rheumatology, reviewing records older than one year more than half the time. Labs (20.3%), office notes (20%) and imaging (17.8%) were the types of medical data older than one year that were reviewed the most frequently overall. Discussion Management questions appear to be the most common reason for e-consultation. E-consultants frequently reviewed historical medical data that is older than one year at the time of the e-consultation, especially in endocrinology, haematology and rheumatology specialties. Practices engaging in e-consultations that require transfer of data may want to include longer time frames of historical information

    Retrospective experience curves are a useful tool for understanding historic technology development, and can contribute to investment program analysis and future cost estimation efforts. This work documents our development of an analysis approach for deriving retrospective experience curves with a variable learning rate, and its application to develop an experience curve for compact fluorescent lamps for the global and North American markets over the years 1990-2007. Uncertainties and assumptions involved in interpreting data for our experience curve development are discussed, including the processing and transformation of empirical data, the selection of system boundaries, and the identification of historical changes in the learning rate over the course of 15 years. In the results that follow, we find that that the learning rate has changed at least once from 1990-2007. We also explore if, and to what degree, public deployment programs may have contributed to an increased technology learning rate in North America. We observe correlations between the changes in the learning rate and the initiation of new policies, abrupt technological advances, including improvements to ballast technology, and economic and political events such as trade tariffs and electricity prices. Finally, we discuss how the findings of this work (1) support the use of segmented experience curves for retrospective and prospective analysis and (2) may imply that investments in technological research and development have contributed to a change in market adoption and penetration.

    To describe healthcare professionals' perceptions of neglect of older people in Mexico. Mistreatment of older people, particularly neglect, has emerged as a significant public health concern worldwide. However, few studies have been conducted to examine neglect of older people in low- and middle-income countries. Most research has focused on estimating the prevalence of neglect in older populations with little emphasis on the perceptions of healthcare professionals and their role in addressing neglect of older people. Qualitative secondary analysis. The parent study consisted of nine focus groups conducted with healthcare professionals at five public hospitals in Mexico. The purpose of the parent study was to perform a needs assessment to determine the feasibility of adapting the Nurses Improving Care for Healthsystem Elders programme to Mexico. A qualitative secondary analysis with directed content analysis approach was used to extract data related to neglect of older people. A total of 89 participants representing healthcare professionals from several disciplines were interviewed. Three themes emerged: (i) The main point is not here; (ii) We feel hopeless; and (iii) We need preparation. Participants reported distress and hopelessness related to neglect of older people. Lack of community-based resources was noted as contributing to neglect. Increased education regarding care of older people for both caregivers and healthcare professionals and greater interdisciplinary collaboration were identified as potential solutions to combat neglect. Community-based services and resource allocation need to be re-evaluated to improve the care of older Mexicans. Interdisciplinary models of care should be developed to address concerns related to neglect of older people. Neglect negatively impacts healthcare professionals' ability to adequately care for older patients. There is a need to invest in community-based services and models of care to address these concerns. © 2017

    Despite the high burden of hip fracture in China, there is limited information on its management. This study investigated the management of hip fractures in a Beijing tertiary hospital and compared practice with that in 180 hospitals in the UK. The findings show a significant gap exists between the countries. The purpose of this study was to determine if the management of older people with hip fractures in a Beijing tertiary hospital is comparable with the UK best practice guidelines for hip fracture management and the UK National Hip Fracture Database 2012, obtained from 180 hospitals. A retrospective audit was undertaken in a large tertiary care hospital in Beijing. Data were compared with the National Hip Fracture Database 2012 collected in 180 hospitals in the UK on the proportion of patients managed according to the UK Blue Book standards. Sixty-six percent of patients were admitted to an orthopaedic ward within 24 h of fracture, while 100 % of patients in the UK were admitted to an orthopaedic ward within 24 h of arrival to an accident and emergency department. Only 8 % of patients received surgery within 48 h of admission compared with 83 % in the UK; 10 % received no surgery compared with 2.5 % in the UK; and 27 % received orthogeriatrician assessment compared with 70 % in the UK. New pressure ulcers developed in 2 % of patients compared with 3.7 % of those in the UK; whereas, 0.3 % of patients were assessed for osteoporosis treatment and 3.8 % received falls assessment, and comparable figures for the UK were 94 and 92 %, respectively. Significant gaps exist in hip fracture management in the Beijing hospital compared with the best practice achieved in 180 UK hospitals, highlighting the need to implement and evaluate proactive strategies to increase the uptake of best practice hip fracture care in China.

    Earthquakes are the most violent type of natural disasters and injuries are the dominant medical problem in the early phases after earthquakes. However, likely because of poor data availability, high-quality research on injuries after earthquakes is lacking. Length of hospital stay (LOS) has been validated as a proxy indicator for injury severity in high-income settings and could potentially be used in retrospective research of injuries after earthquakes. In this study, we assessed LOS as an adequate proxy indicator for severe injury in trauma survivors of an earthquake. A retrospective analysis was conducted using a database of 1,878 injured patients from the 2008 Wenchuan earthquake. Our primary outcome was severe injury, defined as a composite measure of serious injury or resource use. Secondary outcomes were serious injury and resource use, analysed separately. Non-parametric receiver operating characteristics (ROC) and area under the curve (AUC) analysis was used to test the discriminatory accuracy of LOS when used to identify severe injury. An 0.7earthquake survivors. However, LOS was found to be a proxy for major nonorthopaedic surgery and blood transfusion. These findings can be useful for retrospective research on earthquake-injured patients when detailed hospital records are not available.

    Because the concept of whiplash as a causative factor for temporomandibular disorders (TMD) is highly controversial, we decided to do a retrospective analysis of patients treated in our office who had sustained whiplash injuries and were treated for cervical and temporomandibular disorders. The records of 300 patients with TMD preceded by a motor vehicle accident were examined retrospectively. The most common presenting symptoms, in order, were: jaw pain, neck pain, post-traumatic headache, jaw fatigue, and severe temporomandibular joint (TMJ) clicking. The most common TMD diagnoses were: masseter trigger points, closing jaw muscle hyperactivity, TMJ synovitis, opening jaw muscle hyperactivity, and advanced TMJ disk derangement. Based primarily on the physical examination, we concluded that the TMJ and surrounding musculature should be examined similarly to other joints, with no preconceived notion that TMD pathology after whiplash is unlikely.

    Enzyme replacement therapy (ERT) with laronidase, (recombinant human α-L-iduronidase; Aldurazyme) is the primary treatment option for patients with attenuated mucopolysaccharidosis type I (MPS I). This study examined the effect of early ERT on clinical manifestations. This multinational, retrospective case series abstracted data from records of 20 patients with Hurler-Scheie syndrome within nine sibships that included older siblings treated with laronidase after the development of significant clinical symptoms, and younger siblings treated before significant symptomatology. Median age at diagnosis was 5.6 and 0.5 years for older and younger siblings, respectively. Median age at ERT initiation was 7.9 and 1.9 years for older and younger siblings, respectively. Improvement or stabilization of somatic signs and symptoms was more notable in younger siblings. Organomegaly present at onset of ERT improved in the majority of both older and younger siblings. Analysis of physician-rated symptom severity demonstrated that cardiac, musculoskeletal, and cognitive symptoms, when absent or mild in younger siblings at ERT initiation, generally did not develop or progress. The majority of older siblings had height/length Z-scores greater than two standard deviations below the mean (less than -2) at both time points. In general, Z-scores for younger siblings were closer to the sex- and age-matched means at follow-up. These findings suggest early initiation of laronidase, prior to the onset of symptoms in patients with attenuated MPS I, can slow or prevent the development of severe clinical manifestations.

    Background. Few studies have been done that characterize basal cell carcinoma (BCC) in Asians because this tumor is relatively uncommon in this population group. Objective. To characterize BCC in Asians. Methods. We retrospectively examined fifteen patient variables and eight tumor variables of ten Asian patients with BCC and compared these results to those of thirty matched Caucasian controls with BCC. Results. Asians developed their first BCC at an older age than the age of first BCC in Caucasian controls (68.9 years versus 58.3 years; ρ< 0 . 0 5 ). During their lifetime, Asians had fewer BCCs than the number of BCCs in Caucasian controls (1.11 versus 5.41;ρ< 0 . 0 2 ), despite a similar estimated lifetime daily sun exposure (hours/day) for both groups. Compared to BCCs in Caucasian controls, a higher percentage of BCCs in Asians were clinically pigmented (50.0% versus 3.3%; ρ< 0 . 0 1 ). Conclusion. Asians develop BCCs later in life and develop fewer BCCs over their lifetime than Caucasians, despite similar estimated lifetime daily sun exposure. This finding is probably due to skin pigmentation in Asians being more protective of ultraviolet light than skin pigmentation in Caucasians.

It will provide baseline data for to assess PET or PET-CT cost effective potential for staging. A total of 849 patient’s data received from NWCIS databases with various stages of oesophageal cancer between 2001 and 2008. The fundamental activities are retrospective analysis of patient data. In most cases where appropriate, results are presented with 95 percent confidence intervals (CI). Variances between patient groups and variables are assessed using chi-square test. In cases where it deems vital, multiple logistic regression are used to modify for potential confounder such as age and sex. All p-values are two-sided and any value lower than 0.05 were considered to suggest a statistically significant result. Retrospective analysis were categorised into two categories, patients from 2001-2003 considered as pre PET and post PET for 2004-2008. This categorisation allows better comparison of patients’ survival trend to be made between both groups. Rates are presented in percentages and being grouped by tumour characteristics and other variables associated with demographic profile, diagnosis, staging and treatment. Results allowed comparison of oesophageal cancer trends between the pre and post PET-CT introduction such as changes in incidence rate or changes in survival. These data were used to normalise the decision tree model so that cost-effectiveness analysis can be performed across the whole population.

    The objectives of this work were to retrospectively describe the radiographic assessment of INBONE total ankle arthroplasty in 30 patients using validated linear and angular measurements and to correlate these findings with the final surgical outcome over a 2-year follow-up period. Thirty consecutive patients (21 females, nine males; mean age, 64.8 years) underwent INBONE total ankle arthroplasty during 2007-2011. After IRB approval, a retrospective pre- and post-operative radiographic analysis was performed using validated linear and angular measurements. The pre- and post-operative assessment included the tibial angle, talar angle, tibial slope, and coronal deformity. Post-operative measurements also included the talocalcaneal angle, joint space height, talar height, lateral tibial component angle, lateral talar component angle, and anteroposterior tibial component angle. The post-operative bone loss, subluxation, positioning, and subsidence were also assessed. Statistical analysis was performed using two-sample t test and Fisher's exact test. Out of 30 patients, 23 had a successful clinical outcome with intact prosthesis at a 2-year follow-up. The only variables with significant correlation (p < 0.05) to the post-surgical outcome were the lateral talar component angle (p = 0.002) and the mean difference between pre- and post-operative tibial slope (p = 0.001). The coronal deformity had significant mean difference between pre- and post-operative values (p < 0.001); however, it lacked a significant correlation to the final surgical outcome. None of the categorical variables had a significant correlation with post-surgical outcome. In our retrospective study, only the lateral talar component angle and the mean difference between the pre- and post-operative tibial slope had significant correlation with post-surgical outcome in INBONE ankle arthroplasty. These measurements may be helpful in radiographic assessment of the INBONE ankle arthroplasty. (orig.)

  13. Myeloperoxidase mRNA detection for lineage determination of leukemic blasts: retrospective analysis.

    Myeloperoxidase (MPO) mRNA is an early myeloid marker; its detection in the morphologically and immunophenotypically primitive blasts of acute undifferentiated leukemia (AUL) establishes myeloid lineage and allows reclassification as acute myelogenous leukemia with minimal differentiation (AML-MO). We have previously reported a procedure for MPO mRNA detection by RT-PCR (reverse transcription-polymerase chain reaction) and an adaptation for use of routine hematology smears. This variant procedure allows retrospective analysis of mRNA and is used in the present study to evaluate the lineage of leukemic blasts in seven cases with morphology and cytochemistry consistent with AUL. All hematology smears used in this study were air-dried, unstained or Wright-stained and stored at room temperature for periods varying between 3 days and 2 years. MPO mRNA was detected in six cases, establishing the myeloid lineage of the blasts and the diagnosis of AML-MO. In the remaining case, the blasts were MPO mRNA negative, confirming the diagnosis of AUL. The RT-PCR procedure for retrospective mRNA analysis is useful in the clinical setting, due to its high specificity and sensitivity, speed (less than 24 h), safety (no radioactivity) and convenient use of routine hematology smears; it is particularly attractive in clinical situations when fresh or frozen specimens are no longer available at the time when the need for molecular diagnostics becomes apparent.

    Colorectal cancer (CRC) is one of the leading cause of death in European population. It progresses without any symptoms in the early stages or those clinical symptoms are very discrete. The aim of this study was a retrospective analysis of treatment outcomes in patients with colorectal cancer complicated with intestinal perforation. A retrospective analysis of patients urgently operated upon in our Division of General Surgery, because of large intestine perforation, from February 1993 to February 2013 has been made. Results were compared with a group of patients undergoing the elective surgery for colorectal cancer in the same time and Division. Intestinal perforation occurred more often in males (6.52% vs. 6.03%), patients with mucous component in histopathological examination (9.09% vs. 6.01%) and with clinicaly advanced CRC. Patients treated because of perforation had a five-fold higher 30 day mortality rate (9.09% vs. 1.83%), however long-term survival did not differ significantly in both groups. After resectional surgery in 874 patients an intestinal anastomosis was made. Anastomotic leakage was present in 23 (2.6%) patients. This complication occurred six-fold more frequently in a group of patients operated upon because of intestinal perforation (12.20% vs. 2.16%). In patients with CRC complicated with perforation of the colon in a 30-day observation significantly higher rate of complications and mortality was shown, whereas there was no difference in distant survival rates.

    Abstract Olfactory dysfunction is common among older adults and affects their safety, nutrition, quality of life, and mortality. More importantly, the decreased sense of smell is an early symptom of neurodegenerative diseases such as Parkinson disease (PD) and Alzheimer disease. However, the genetic determinants for the sense of smell have been poorly investigated. We here performed the first genome-wide meta-analysis on the sense of smell among 6252 US older adults of European descent from t...

  16. Exploring the Knowledge Structure of Nursing Care for Older Patients With Delirium: Keyword Network Analysis.

    Prevention of delirium is considered a critical part of the agenda for patient safety and an indicator of healthcare quality for older patients. As the incidence rate of delirium for older patients has increased in recent years, there has been a significant expansion in knowledge relevant to nursing care. The purposes of this study were to analyze the knowledge structure and trends in nursing care for older adults with delirium based on a keyword network analysis, and to provide a foundation for future research. Data analysis showed that knowledge structure in this area consists of three themes of research: postoperative acute care for older patients with delirium, prevention of delirium for older patients in intensive care units, and safety management for the improvement of outcomes for patients with delirium. Through research trend analysis, we found that research on care for patients with delirium has achieved both quantitative and qualitative improvements over the last decades. Concerning future research, we propose the expansion of patient- and family-centered care, community care, specific nursing interventions, and the integration of new technology into care for patients with delirium. These results provide a reference framework for understanding and developing nursing care for older adults with delirium.

    Kinetic therapy (KT) has been shown to reduce complications and to shorten hospital stay in trauma patients. Data in non-surgical patients are inconclusive, and kinetic therapy has not been tested in patients with cardiogenic shock. The present analysis compares KT with standard care in patients with cardiogenic shock. A retrospective analysis of 133 patients with cardiogenic shock admitted to 1 academic heart center was performed. Patients with standard care (SC, turning every 2 h by the staff) were compared with kinetic therapy (KT, using oscillating air-flotation beds). 68 patients with KT were compared with 65 patients with SC. Length of ventilator therapy was 11 days in KT and 18 days in SC (p=0.048). The mortality was comparable in both groups. Pneumonia occurred in 14 patients in KT and 39 patients in SC (ppatients treated with kinetic therapy. The use of KT shortens hospital stay and reduces rates of pneumonia and pressure ulcers as compared to SC.

    The debate over the fact that experimental drugs proposed for the treatment of stroke fail in the translation to the clinical situation has attracted considerable attention in the literature. In this context, we present a retrospective pooled analysis of a large data set from preclinical studies, to examine the effects of early versus late administration of intravenous recombinant tissue-type plasminogen activator. We collected data from 26 individual studies from 9 international centers (13 researchers; 716 animals) that compared recombinant tissue-type plasminogen activator with controls, in a unique mouse model of thromboembolic stroke induced by an in situ injection of thrombin into the middle cerebral artery. Studies were classified into early (stroke in mice. The power analysis reveals that a multicenter trial would require 123 animals per group instead of 40 for a single-center trial. © 2016 American Heart Association, Inc.

    The evolution of Canadian nursing curricula has mutually influenced and reflected nursing's historical course: nursing practice and education are inextricably linked. This paper is a critical retrospective analysis of the evolution of nursing curricula in Canada from the 20th century to the present. Falk Rafael's (1996) dialectic exploration of power and caring in nursing guides the analysis. An ordered, assimilated, and empowered curriculum development framework results. Foucault's (1980) work in the sociology of knowledge and Belenky, Clinchy, Goldberger, and Tarule's (1986) epistemological conceptualization of women's knowledge development are incorporated. The intricacies of the relationship between nursing curriculum development and Canadian history, the navigation of societal paradoxes that mutually drive and inform education and practice, and the instrumental need for nursing education research are considered. A fourth and new dialectic layer is suggested that places nursing on the inter-professional team of architects of a co-constructed emancipatory curriculum.

    This analysis is the first-ever comprehensive assessment of the benefits and impacts of state renewable portfolio standards (RPSs). This joint National Renewable Energy Laboratory-Lawrence Berkeley National Laboratory project provides a retrospective analysis of RPS program benefits and impacts, including greenhouse gas emissions reductions, air pollution emission reductions, water use reductions, gross jobs and economic development impacts, wholesale electricity price reduction impacts, and natural gas price reduction impacts. Wherever possible, benefits and impacts are quantified in monetary terms. The paper will inform state policymakers, RPS program administrators, industry, and others about the costs and benefits of state RPS programs. In particular, the work seeks to inform decision-making surrounding ongoing legislative proposals to scale back, freeze, or expand existing RPS programs, as well as future discussions about increasing RPS targets or otherwise increasing renewable energy associated with Clean Power Plan compliance or other emission-reduction goals.

    Full Text Available Introduction: The number of elder patients with severe psychiatric illnesses other than depression is increasing. Electroconvulsive therapy (ECT has a special role in the treatment of late-life depression and other psychiatric conditions in the elderly. Using ECTs in the elderly could be difficult. In an Indian setting, ECT in the geriatric population is used as last resort of treatment which is in contrast to Western countries. There is dearth of data available for the use of ECT in the elderly in India. Methodology: Retrospective data review was carried out to identify patients 55 years or older who had received ECT from January 2014 to June 2016 in tertiary care teaching hospital in a metropolitan city in India. Results: A total of 304 ECTs were administered to 25 elderly aged> 55 years with average of 12 ECTs per patient. Schizophrenia (56% was the most common diagnosis among patients who were considered for ECT, and this was followed by major depression without psychotic features (24% and major depression with psychotic features (8%. The most common indication to start ECT was nonresponsiveness to medications (92%. There was an increase in mean Mini-Mental State Examination (MMSE scores from baseline (23.42 to the end of the sixth (24.60 and last ECT (24.60. Duration of current used during ECT had positive correlation with MMSE. Patients with comorbid medical illness (20% received ECT without any complication. Conclusions: This study adds to scarce database on the use of ECT in old-age patients in India and adds to evidence that ECT is safe and effective treatment in old age with no negative impact on cognition.

    Palliative irradiation of osteolytic lesions is a considerable component in the treatment for patients with multiple myeloma. In this study, we analyzed the efficacy of irradiation in these patients. We retrospectively analyzed 153 patients with multiple myeloma who were admitted to our department between 1989 and 2013. According to the staging system of Durie & Salmon 116 patients were classified as stage III. 107/153 patients were treated with radiotherapy of at least one and up to 6 bony lesions at different times. In order to evaluate the effect of local radiotherapy on pain relief and bone recalcification a uni- and multivariate analysis was performed using a binary logistic regression model to correct for multiple measurements. Complete information on dose, fractionation and volume of radiotherapy was available from 81 patients treated in 136 target volumes for pain relief, and from 69 patients treated in 108 target volumes for recalcification. Total radiation doses varied between 8 Gy to 50 Gy (median dose 25 Gy in 2.5 Gy fractions, 5 times a week). Radiotherapy resulted in complete local pain relief in 31% and partial local pain relief in 54% of the patients. In the univariate analysis, higher total radiation doses (p = 0.023) and higher age (p = 0.014) at the time of radiotherapy were significantly associated with a higher likelihood of pain relief, whereas no significant association was detected for concurrent systemic treatment, type and stage of myeloma and location of bone lesions. The same variables were independent predictors for pain relief in the multivariate analysis. Recalcification was observed in 48% of irradiated bone lesions. In the uni- and multivariate analysis higher radiation doses were significantly associated (p = 0.048) with an increased likelihood of recalcification. Side effects of radiotherapy were generally mild. Higher total biological radiation doses were associated with better pain relief and recalcification in this

    The purpose of this retrospective study was to determine the clinical practices for prescribing yoked prisms, as well as to assess related patient responses, in a sample of visually-symptomatic patients having acquired brain injury (ABI). The clinical records of individuals with acquired brain injury (ABI) that were assessed for yoked prisms were reviewed retrospectively. This query resulted in 60 patient records for analysis between January 2011 and December 2012. The following diagnostic groups were analysed: homonymous hemianopsia (HH)/homonymous quadranopsia, abnormal egocentric localization (AEL) and visual neglect. HH/homonymous quadranopsia (58.3%) was the primary indication to prescribe yoked prisms, followed by visual neglect/unilateral spatial inattention (USI) (40.0%) and AEL (11.7%). The most common favourable patient responses were increased awareness of their blind visual field and improved gait, mobility and balance. The magnitude and direction of prisms prescribed were dependent upon the subjective responses in patients manifesting AEL. In contrast, base direction was dependent upon the direction of visual field loss in patients with HH/homonymous quadranopsia and visual neglect. Two-thirds of the present sample population responded favourably to the yoked prisms. The results of the present study should prove useful to clinicians for the successful prescription of yoked prisms as a treatment modality in patients presenting with the above three diagnoses.

    The aim of this study was to determine the possibility of non-operative treatment via retrospective analysis of our patients. Fifty patients with penetrating hepatic injuries were examined retrospectively with respect to trauma scores, associated injuries, complications, and mortality parameters. Thirteen injuries were caused by firearms, whereas 37 injuries were caused by stab wounds. Forty-three patients (86%) underwent laparotomy and 7 patients (14%) were monitored by CT and clinical findings (nonoperative group, NO group). The laparotomies were evaluated as non-therapeutic in 11 patients (22%) (NTL group) and therapeutic in 32 patients (64%) (TL group). The morbidity and mortality rates were 40 and 10%, respectively. RTS and ISS scores of the nonsurviving and the surviving patients were significantly different. The rates of major venous, grade IV-V hepatic injuries, and gunshot wounds were significantly higher in the nonsurviving patients when compared to the surviving patients. Major venous and grade IV-V hepatic injuries were the primary factors determining mortality and these injuries generally occurred as a result of firearm injuries. NTL occurring at a rate of 22% would decrease to 2% if 'RTS <7' criteria was added to the hemodynamic instability and/or peritoneal irritation findings determining surgical candidacy.

    Falls are a serious health problem for older adults. Several studies have identified the decline of postural balance as one of the main risk factors for falls. Contrary to what may be believed, the capability of force platform measurements to predict falls remains uncertain. The focus of this narrative review is the identification of postural characteristics of older adults at risk of falling using both static and dynamic postural balance assessments. The literature analysis was conducted on Medline/PubMed. The search ended in May 2015. Centre of pressure (CoP) path length, CoP velocity and sway in medial lateral and anterior-posterior are the variables that distinguish older adult fallers from non-fallers. Recommendations to medical personnel on how to provide efficient balance training for older adults are offered, discussing the relevance and limitations of postural stability on static and dynamic board in falling risk prevention.

    Leisure is an important quality of life factor for older Korean immigrants. The purpose of this study was to explore leisure benefits associated with health among older Korean immigrants. A total of 18 individuals participated in the study. Using interpretative phenomenological analysis (IPA), three themes emerged from participants’ personal statements and experiences: (a) experiencing psychological benefits, (b) strengthening social connections, and (c) coping with acculturative stress. The findings indicate that leisure provided a context in which older Korean immigrants created an emotional and social support system that helped them to experience psychological and social benefits. This research suggested that older Korean immigrants used leisure as a coping mechanism that results in health and well-being. PMID:27914195

    2015-01-01

    Cross-cultural studies of advertising representations of older people are relatively scarce. This article aims to fill in this gap via a comparison between Taiwan and the United Kingdom, employing a combination of quantitative content analysis and the qualitative grounded theory method. The content-analysis phase reveals underrepresentation of older people in both countries' advertising contexts, as well as representational differences between Taiwan and the United Kingdom in terms of older characters' role salience, the products, physical settings, and social networks they are associated with. The grounded-theory phase yields nine prototypes of older people along with subcategories to conceptualize the qualities of older people as they appear in TV ads in these countries. The findings are discussed in relation to the stereotyping of older people and transformed into hypothetical statements to be modified in future research. In conclusion, the Confucian tradition of filial piety is still found to be important in explaining the observed cross-cultural differences, but the emergence of new norms about aging in Taiwanese advertising also suggests that this tradition may be in decline. © The Author(s) 2015.

  12. Predictive Factors of In-Stent Restenosis in Renal Artery Stenting: A Retrospective Analysis

    Purpose. To retrospectively evaluate the role of clinical and procedural factors in predicting in-stent restenosis in patients with renovascular disease treated by renal artery stenting. Methods. From 1995 to 2002, 147 patients underwent renal artery stenting for the treatment of significant ostial atherosclerotic stenosis. Patients underwent strict clinical and color-coded duplex ultrasound follow-up. Ninety-nine patients (111 stents), with over 6 months of continuous follow-up (mean 22±12 months, range 6-60 months), were selected and classified according to the presence (group A, 30 patients, 32 lesions) or absence (group B, 69 patients, 79 lesions) of significant in-stent restenosis. A statistical analysis was performed to identify possible preprocedural and procedural predictors of restenosis considering the following data: sex, age, smoking habit, diabetes mellitus, hypertension, serum creatinine, cholesterol and triglyceride levels, renal artery stenosis grade, and stent type, length and diameter. Results. Comparing group A and B patients (χ 2 test), a statistically significant relation was demonstrated between stent diameter and length and restenosis: the risk of in-stent restenosis decreased when the stent was ≥6 mm in diameter and between 15 and 20 mm in length. This finding was confirmed by multiple logistic regression analysis. Stent diameter and length were proved to be significantly related to in-stent restenosis also when evaluating only patients treated by Palmaz stent (71 stents). Conclusion. Although it is based on a retrospective analysis, the present study confirms the importance of correct stent selection in increasing long-term patency, using stents of at least 6 mm in diameter and with a length of approximately 15-20 mm

    A retrospective analysis of presurgical clinical picture and blood pressures of 34 patients with histologically verified pheochromocytoma. Assessment of clinical state, blood pressure and prognosis in the course of patients control hospitalizations from 2001 to 2002. The study was designed as a synoptic one, based on a retrospective analysis of 34 patients records with histologically verified pheochromocytoma (26 women and 8 men). Our assessments of clinical symptomatology, maximum paroxysmal hypertension values, average blood pressure values in patients with persistent arterial hypertension, arterial hypertension grade and circadian index were based on patients records. Patients epinephrectomies were followed during their control hospitalizations to assess their clinical state. Their blood pressures were evaluated by means of their circadian monitoring. From the 34 patients, 21 were diagnosed with solitary pheochromocytomas. The circadian index persistence analysis prior to the surgery was associated with circadian blood pressure monitoring in 21 patients. It was lost in 57% of patients. During their control hospitalization as many as 82% of patients preserved their circadian blood pressure variability with a more than 10% decrease in the night time, 5 patients did not preserve their circadian blood pressure variability. Seven from the original 34 patients died: Three of them died from their primary disease, one 63-year old man died from shock following tumour extirpation. The death of other 3 patients was not associated with their primary disease. Long-lasting survival of patients with pheochromocytoma after surgical treatment--except for those with malignant disease--was demonstrated. Although our assessment of the resulting treatment effects was positive, a long-term follow-up is inevitable because of a difficult pathologic-anatomical verification of the malignant nature of the disease as well as of the risk of tumour relapse assessment.

    ABSTRACT: BACKGROUND: To inform Danish health care reform efforts, we compared health care system inputs and performance and assessed the usefulness of these comparisons for informing policy. METHODS: Retrospective analysis of secondary data in the Danish Health Care System (DHS) with 5.3 million...... citizens and the Kaiser Permanente integrated delivery system (KP) with 6.1 million members in California. We used secondary data to compare population characteristics, professional staff, delivery structure, utilisation and quality measures, and direct costs. We adjusted the cost data to increase...... comparability. RESULTS: A higher percentage of KP patients had chronic conditions than did patients in the DHS: 6.3% vs. 2.8% (diabetes) and 19% vs. 8.5% (hypertension), respectively. KP had fewer total physicians and staff compared to DHS, with134 physicians/100,000 individuals versus 311 physicians/100...

    Full Text Available Abstract Background Anemia and poor nutrition have been previously described as independent risk factors for death among HIV-infected children. We sought to describe nutritional status, anemia burden and HIV disease correlates among infected children in India. Methods We analyzed retrospective data from 248 HIV-infected children aged 1–12 years attending three outpatient clinics in South India (2004–2006. Standard WHO definitions were used for anemia, HIV staging and growth parameters. Statistical analysis included chi square, t tests, univariate and multivariate logistic regression analyses. Results The overall prevalence of anemia (defined as hemoglobin Conclusion The high prevalence and strong interrelationship of anemia and poor nutrition among HIV-infected children in India, particularly those living in rural areas underscores the need for incorporating targeted nutritional interventions during national scale up of care, support and treatment among HIV-infected children.

    Retrospective evaluation (RE) of event sequences is known to be biased in various ways. The present paper presents a series of studies that examined the suggestion that the moments that are the most accessible in memory at the point of RE contribute to these biases. As predicted by this memory-based analysis, Experiment 1 showed that pleasantness ratings of word lists were biased by the presentation position of a negative item and by how easy the negative information was to retrieve. Experiment 2 ruled out the hypothesis that these findings were due to the dual nature of the task called upon. Experiment 3 further manipulated the memorability of the negative items--and corresponding changes in RE were as predicted. Finally, Experiment 4 extended the findings to more complex stimuli involving event narratives. Overall, the results suggest that assessments were adjusted based on the retrieval of the most readily available information.

    This research is aimed at understanding the dynamics of collaborative multi-party discourse across multiple communication modalities. Before we can truly make sig-nificant strides in devising collaborative communication systems, there is a need to understand how typical users utilize com-putationally supported communications mechanisms such as email, instant mes-saging, video conferencing, chat rooms, etc., both singularly and in conjunction with traditional means of communication such as face-to-face meetings, telephone calls and postal mail. Attempting to un-derstand an individual’s communications profile with access to only a single modal-ity is challenging at best and often futile. Here, we discuss the development of RACE – Retrospective Analysis of Com-munications Events – a test-bed prototype to investigate issues relating to multi-modal multi-party discourse.

    Despite progress in the initial management of glioblastoma (GB), the vast majority of patients will experience recurrence within 2-3 years. The medical treatment of these recurrences is being modified by the use of antiangiogenic therapies. Twenty-four patients, who relapsed from GB after chemoradiation followed by adjuvant temozolomide in Rennes, were treated by conventional chemotherapy (nitrosourea) or by the combination of irinotecan and bevacizumab. In this retrospective analysis, overall survival from diagnosis of recurrence was significantly longer in patients treated with the combination of bevacizumab and irinotecan than with nitrosourea (5 months versus 11.5 months). The combination of irinotecan and bevacizumab appeared to provide clinical benefit to patients with recurrent GB.

    Full Text Available Complement-mediated cytotoxic antibodies in conventional cross match, often result in misappropriation of true positives and borderline positives which are detrimental to allograft survival. Flow cross matches (FCXM are sensitive to capture even non comple-ment fixing cytotoxic antibodies. This retrospective study evaluates the utility of FCXM in effectively predicting acute allograft rejection. A total of 17 cases were processed for FCXM (T and B cell of whom seven had no rejection episodes, while the remaining 11 had acute rejection despite negative cross match and panel reacting antibodies being ne-gative (less than 20%. The sensitivity and specificity of the FCXM outcome demons-trated that positive B-cell FCXM has potential to be a good tool in pre-transplant scree-ning. The current analysis proposes the possible utility of B-cell positive FCXM as a more sensitive parameter in predicting acute allograft rejection prior to transplantation.

    The scar is a major problem in the medical profession. Its timely treatment is very important for the better outcome of the scar treatment and for the improvement of the life quality of the patients. The aim of this study was retrospectively analyzed the epidemiological characteristics affecting the efficacy of the scar surgical treatment of the people in the western part of China. Total 414 scar cases were retrospectively analyzed to clarify the epidemiological characteristics and the factors affecting the scar surgical treatment efficacy. The factors included were sex, age, area distribution, treatment seasons, injury sites, injury causes, and the time from scarring to the surgical treatment. All scar cases were surgically treated with the repairing technology including skin graft, flap and soft tissue dilation. There were 206 males and 208 females with the average age 20.53±12.9 years (age range 1-68 years). The patient proportions in the age groups of 0-20, 21-40 and >40 years were 61.4% (254 cases), 29.2% (121 cases), and 9.4% (39 cases) respectively. The patient's attendance rate reached the highest during the summer and winter. Most patients were from the rural areas with an increasing tendency each year. The burn scars were the most abundant and the injury sites were mostly the head and face. Univariate analysis showed that the time from scarring to the surgical treatment and the injury sites were significantly influenced the scar surgical treatment efficacy. Logistic regression analysis demonstrated that the injured sites of the head and face significantly influenced the scar surgical treatment efficacy. With the development of economy in China, more scar patients especially younger and children visit doctors predominantely from the rural areas. Usually, they get their scars in the exposed area of their bodies (head and face) which seriously affect the patient's appearance and function. Factors influencing the scar surgical treatment efficacy has

    Aim of the study Colorectal cancer (CRC) is one of the leading cause of death in European population. It progresses without any symptoms in the early stages or those clinical symptoms are very discrete. The aim of this study was a retrospective analysis of treatment outcomes in patients with colorectal cancer complicated with intestinal perforation. Material and methods A retrospective analysis of patients urgently operated upon in our Division of General Surgery, because of large intestine perforation, from February 1993 to February 2013 has been made. Results were compared with a group of patients undergoing the elective surgery for colorectal cancer in the same time and Division. Results Intestinal perforation occurred more often in males (6.52% vs. 6.03%), patients with mucous component in histopathological examination (9.09% vs. 6.01%) and with clinicaly advanced CRC. Patients treated because of perforation had a five-fold higher 30 day mortality rate (9.09% vs. 1.83%), however long-term survival did not differ significantly in both groups. After resectional surgery in 874 patients an intestinal anastomosis was made. Anastomotic leakage was present in 23 (2.6%) patients. This complication occurred six-fold more frequently in a group of patients operated upon because of intestinal perforation (12.20% vs. 2.16%). Conclusions In patients with CRC complicated with perforation of the colon in a 30-day observation significantly higher rate of complications and mortality was shown, whereas there was no difference in distant survival rates.

    The purpose of this study was to develop a prediction model for the characteristics of older adults with depression using the decision tree method. A large dataset from the 2008 Korean Elderly Survey was used and data of 14,970 elderly people were analyzed. Target variable was depression and 53 input variables were general characteristics, family & social relationship, economic status, health status, health behavior, functional status, leisure & social activity, quality of life, and living environment. Data were analyzed by decision tree analysis, a data mining technique using SPSS Window 19.0 and Clementine 12.0 programs. The decision trees were classified into five different rules to define the characteristics of older adults with depression. Classification & Regression Tree (C&RT) showed the best prediction with an accuracy of 80.81% among data mining models. Factors in the rules were life satisfaction, nutritional status, daily activity difficulty due to pain, functional limitation for basic or instrumental daily activities, number of chronic diseases and daily activity difficulty due to disease. The different rules classified by the decision tree model in this study should contribute as baseline data for discovering informative knowledge and developing interventions tailored to these individual characteristics.

    Rape and abuse of women are common occurrences, which, many a times go unspoken due to social stigma or fear of retribution. Rape is a crime not against a single human being but against the entire humanity. For granting justice to the rape survivor it becomes necessary that such matters are properly presented before the Courts of Law. Healthcare workers play an important role in this regard because they are the first person who examine the rape victims. They prepare a documented record of medical condition of rape victim and do relevant sample collection. The objective of this study is to analyse demographic and event characteristics of rape victims who presented to the Emergency Department in tertiary care, Delhi after sexual assault. Data was retrospectively collected from the medico legal register of the Department of Obstetrics and Gynecology between June 2010 to December 2013. We noted a marked increase in the number of cases. Mean age of victims was 17 and most belonged to the lower socio-economic strata of the society. Use of sedatives and physical trauma was not common. Victims often knew the perpetrator of the event. Most (58%) of them reported within one day of the incident. Major degrees of perineal tears were seen in young victims. By understanding the demography of the sexual assault victims, we need to train our doctors for proper evidence collection not just in a government set up but also in private clinics, to help rape victims get justice and proper medical treatment.

    Purpose Osteosarcoma (OS) is the most common primary bone tumor. Despite complete surgical removal and intensive chemotherapeutic treatment, 30%-35% of patients with OS have local or systemic recurrence. Some patients survive multiple recurrences, but overall survival after OS recurrence is poor. This analysis aims to describe and identify factors influencing post-relapse survival (PRS) after a second OS relapse. Methods This is a retrospective analysis of 60 patients with a second relapse of OS of the extremities in 2 Italian centers between 2003 and 2013. Results Treatment for first and subsequent relapses was planned according to institutional guidelines. After complete surgical remission (CSR) following the first recurrence, patients experienced a second OS relapse with a median disease-free interval (DFI) of 6 months. Lung disease was prevalent: 44 patients (76%) had pulmonary metastases. Survival after the second relapse was 22% at 5 years. Lung disease only correlated with better survival at 5 years (33.6%) compared with other sites of recurrence (5%; p = 0.008). Patients with a single pulmonary lesion had a better 5-year second PRS (42%; p = 0.02). Patients who achieved a second CSR had a 5-year second PRS of 33.4%. Chemotherapy (p<0.001) benefited patients without a third CSR. Conclusions This analysis confirms the importance of an aggressive, repeated surgical approach. Lung metastases only, the number of lesions, DFI and CSR influenced survival. It also confirms the importance of chemotherapy in patients in whom surgical treatment is not feasible.

    To correlate shoulder ultrasound and radiography with F-FDG PET-CT to establish FDG uptake and therefore range of metabolic activity, as defined by SUV analysis, in various symptomatic shoulder pathologies. Retrospective database query was performed for shoulder ultrasound and PET-CT scans between January 2012 and January 2017. Patients who had both studies within 1 year were included. Age- and sex-matched control patients with PET-CT scans only were also included. Retrospective image review determined shoulder pathology, and F-FDG SUVmax was measured using regions of interest placed at the glenohumeral joint, rotator cuff/bursa, and bicipital groove. Glenohumeral and acromioclavicular osteoarthrosis was assessed by radiography using the Kellgren-Lawrence classification system. Thirty-three patients had both imaging studies within 1 year. Ten patients (11 cases) were included, ranging in age from 56 to 90 years (mean, 67.9 years). Control subjects were selected among patients receiving PET-CT within 1 week of symptomatic patients. Glenohumeral osteoarthrosis was mild in 3 (27%), moderate in 2 (18%), and severe in 2 (18%). Six full-thickness rotator cuff tears (55%) were identified. SUVmax means were compared between the pathologic and control groups and were significantly higher in the former: glenohumeral joint (1.96 vs 1.32; P = 0.016), rotator cuff/bursa (2.80 vs 2.0; P = 0.005), and bicipital groove (2.19 vs 1.48; P = 0.007). The highest values were seen in full-thickness rotator cuff tear and severe biceps tenosynovitis. Increased metabolic activity about the shoulder is associated with a spectrum of rotator cuff, glenohumeral joint, and other soft tissue pathology that can be correlated with diagnostic ultrasound findings.

    OBJECTIVE To identify historical and necropsy findings suggestive of neglect or abuse of dogs and cats by retrospective analysis of necropsy reports from a veterinary diagnostic laboratory. DESIGN Retrospective cohort study. SAMPLE 119 necropsy reports of dogs and cats. PROCEDURES Necropsy reports from February 2001 to May 2012 were electronically searched to identify potential animal abuse or neglect cases. Cases were selected and categorized according to a previously proposed method for classification of animal abuse. Inclusion criteria included signs of neglect, nonaccidental injury (NAI; blunt-force or sharp-force trauma, gunshot, burns, drowning, asphyxiation, and suspicious intoxications), and sexual abuse. Poor preservation of cadavers, age abuse cases, determined on the basis of all necropsies performed in the study period, was 73 of 8,417 (0.87%) in dogs and 46 of 4,905 (0.94%) in cats. Neglect and NAI were commonly identified in cats; NAI was most commonly found in dogs. Gunshot and blunt-force trauma were the most common NAIs in dogs and cats, respectively. Pit bull-type dogs (29/73 [40%]) were overrepresented in several abuse categories. Most cats (29/46 [63%]) were domestic shorthair, but no breed association was found. Most (41/71 [58%]) affected animals with age data available were ≤ 2 years old. CONCLUSIONS AND CLINICAL RELEVANCE Approximately 1% of dogs and cats necropsied in the study period had signs suggestive of abuse. Medical findings alone are not necessarily indicative of abuse, but some findings can increase the index of suspicion.

    Combined chemo- and radiotherapy are established in breast cancer treatment. Chemotherapy is recommended prior to radiotherapy but decisive data on the optimal sequence are rare. This retrospective analysis aimed to assess the role of sequencing in patients after mastectomy because of advanced locoregional disease. A total of 212 eligible patients had a stage III breast cancer and had adjuvant chemotherapy and radiotherapy after mastectomy and axillary dissection between 1996 and 2004. According to concerted multi-modality treatment strategies 86 patients were treated sequentially (chemotherapy followed by radiotherapy) (SEQgroup), 70 patients had a sandwich treatment (SW-group) and 56 patients had simultaneous chemoradiation (SIM-group) during that time period. Radiotherapy comprised the thoracic wall and/or regional lymph nodes. The total dose was 45–50.4 Gray. As simultaneous chemoradiation CMF was given in 95.4% of patients while in sequential or sandwich application in 86% and 87.1% of patients an anthracycline-based chemotherapy was given. Concerning the parameters nodal involvement, lymphovascular invasion, extracapsular spread and extension of the irradiated region the three treatment groups were significantly imbalanced. The other parameters, e.g. age, pathological tumor stage, grading and receptor status were homogeneously distributed. Looking on those two groups with an equally effective chemotherapy (EC, FEC), the SEQ- and SW-group, the sole imbalance was the extension of LVI (57.1 vs. 25.6%, p < 0.0001). 5-year overall- and disease free survival were 53.2%/56%, 38.1%/32% and 64.2%/50%, for the sequential, sandwich and simultaneous regime, respectively, which differed significantly in the univariate analysis (p = 0.04 and p = 0.03, log-rank test). Also the 5-year locoregional or distant recurrence free survival showed no significant differences according to the sequence of chemo- and radiotherapy. In the multivariate analyses the sequence had no

    Major trauma in older people is a significant health burden in the developed world. The aging of the population has resulted in larger numbers of older patients suffering serious injury. Older trauma patients are at greater risk of death from major trauma, but the reasons for this are less well understood. The aim of this review was to identify the factors affecting mortality in older patients suffering major injury. A systematic review of Medline, Cinhal and the Cochrane database, supplemented by a manual search of relevant papers was undertaken, with meta-analysis. Multi-centre cohort studies of existing trauma registries that reported risk-adjusted mortality (adjusted odds ratios, AOR) in their outcomes and which analysed patients aged 65 and older as a separate cohort were included in the review. 3609 papers were identified from the electronic databases, and 28 from manual searches. Of these, 15 papers fulfilled the inclusion criteria. Demographic variables (age and gender), pre-existing conditions (comorbidities and medication), and injury-related factors (injury severity, pattern and mechanism) were found to affect mortality. The 'oldest old', aged 75 and older, had higher mortality rates than younger patients, aged 65-74 years. Older men had a significantly higher mortality rate than women (cumulative odds ratio 1.51, 95% CI 1.37-1.66). Three papers reported a higher risk of death in patients with pre-existing conditions. Two studies reported increased mortality in patients on warfarin (cumulative odds ratio 1.32, 95% CI 1.05-1.66). Higher mortality was seen in patients with lower Glasgow coma scores and systolic blood pressures. Mortality increased with increased injury severity and number of injuries sustained. Low level falls were associated with higher mortality than motor vehicle collisions (cumulative odds ratio 2.88, 95% CI 1.26-6.60). Multiple factors contribute to mortality risk in older trauma patients. The relation between these factors and

    In the security domain, cameras are important to assess critical situations. Apart from fixed surveillance cameras we observe an increasing number of sensors on mobile platforms, such as drones, vehicles and persons. Mobile cameras allow rapid and local deployment, enabling many novel applications and effects, such as the reduction of violence between police and citizens. However, the increased use of bodycams also creates potential challenges. For example: how can end-users extract information from the abundance of video, how can the information be presented, and how can an officer retrieve information efficiently? Nevertheless, such video gives the opportunity to stimulate the professionals' memory, and support complete and accurate reporting. In this paper, we show how video content analysis (VCA) can address these challenges and seize these opportunities. To this end, we focus on methods for creating a complete summary of the video, which allows quick retrieval of relevant fragments. The content analysis for summarization consists of several components, such as stabilization, scene selection, motion estimation, localization, pedestrian tracking and action recognition in the video from a bodycam. The different components and visual representations of summaries are presented for retrospective investigation.

    Full Text Available Paracetamol is one of the most commonly used analgesics and antipyretics available without limits as preparations of the OTC group (over the counter drugs. Overdose and poisoning with this drug always brings about the risk of acute hepatic failure. The objective of the study was a retrospective evaluation of patients hospitalized in the Paediatric Clinic during the period 2004–2012 due to poisoning with paracetamol.The analysis covered 44 patients hospitalized in the Paediatric Clinic during 2004–2012 due to poisoning with paracetamol. Patients were divided into three groups: intentional poisonings, accidental poisonings, and drug overdose.During the period of the study, 44 patients aged 2.1–17.1, poisoned with paracetamol, were hospitalized. Among these patients there were 30 (68.2% cases of intentional poisonings, 10 (22.7% of accidental poisonings, and only 4 patients (9.1% were children hospitalized after a paracetamol overdose. The majority of patients in all groups were females (93.3%.Paracetamol intoxication may occur after exceeding a single allowable dose, in the case of intentional poisoning, more rarely after exceeding the daily dose, in the case of intense pain complaints, or in the treatment of persistent fever.Based on the analysis performed, an increase was observed in the frequency of poisoning with paracetamol, especially intentional poisoning. Unlimited access to paracetamol as an OTC drug should be reconsidered.

    The Modern-Era Retrospective analysis for Research and Applications, version 2 (MERRA-2) is a global atmospheric reanalysis produced by the NASA Global Modeling and Assimilation Office (GMAO). It spans the satellite observing era from 1980 to the present. The goals of MERRA-2 are to provide a regularly-gridded, homogeneous record of the global atmosphere, and to incorporate additional aspects of the climate system including trace gas constituents (stratospheric ozone), and improved land surface representation, and cryospheric processes. MERRA-2 is also the first satellite-era global reanalysis to assimilate space-based observations of aerosols and represent their interactions with other physical processes in the climate system. The inclusion of these additional components are consistent with the overall objectives of an Integrated Earth System Analysis (IESA). MERRA-2 is intended to replace the original MERRA product, and reflects recent advances in atmospheric modeling and data assimilation. Modern hyperspectral radiance and microwave observations, along with GPS-Radio Occultation and NASA ozone datasets are now assimilated in MERRA-2. Much of the structure of the data files remains the same in MERRA-2. While the original MERRA data format was HDF-EOS, the MERRA-2 supplied binary data format is now NetCDF4 (with lossy compression to save space).

    Real-world data on patient outcomes and treatment patterns in multiple myeloma (MM) are limited. The present noninterventional, observational, retrospective analysis of prospectively collected Czech patient medical record data from the Registry of Monoclonal Gammopathies estimated real-world outcomes in adults with a diagnosis of symptomatic MM made between May 2007 and June 2014. In total, 2446 patients had initiated first-line treatment. The median overall survival since the diagnosis (primary endpoint) was 50.3 months (95% confidence interval, 46.1-54.5 months) and decreased with each successive treatment line. A similar trend was observed for progression-free survival and the depth of response. In line with European guidelines and clinical practice, bortezomib-, thalidomide-, and lenalidomide-based regimens were most commonly used across all treatment lines (42.3%, 28.9%, and 18.4%, respectively). In the first line, bortezomib and thalidomide were used most often, with lenalidomide the most commonly used agent in the relapse setting (second to fourth lines). Exploratory analyses revealed that younger age (≤ 65 years), lower international staging system stage, and previous stem cell transplantation were associated with significant improvements in overall and progression-free survival, especially in the early treatment lines. The present study is the first analysis of Czech data from the Registry of Monoclonal Gammopathies, and it provides important insights into the real-world management of MM for physicians and healthcare providers.

    Retrospective analysis of diversity and species composition of marine macroalgae of Hainan Island in the period 1933-1992 is presented in this paper. There are two extensive sample collection periods of benthic macroalgae: the early collection (EC) covers a period between the early 1930s and the 1980s before considerable urbanization and reef degradation took place and a late collection (LC) was performed in 1990/1992 during a phase of rapid urbanization. Analysis of data also including an earlier published inventory of green algae covering the same collection sites (Titlyanov et al. 2011a) revealed that the marine flora of the island comprises 426 taxa in total, with 59% red algae, 18% brown algae and 23% green algae. In total 59 species of red algae, 11 species of brown algae and 37 species of green algae sampled during the LC are new records for Hainan Island. Considerable floristic changes between EC and LC became evident. In the LC there were significantly more filamentous, tubular or fine blade-like, and often epiphytic, green and red algae with a high surface-to-volume ratio. Additionally a reduction of green, brown and red algal species with larger fleshy or foliose thalli and a low surface-to-volume ratio was observed. It is assumed that the changes reflect the degradation of the coral reef ecosystem around Hainan, which was damaged by human activities especially in the 1950s-1970s.

    The aim of this retrospective study is to test the hypothesis that the use of spinal analgesia shortens the length of hospital stay after partial nephrectomy. We reviewed all patients undergoing partial nephrectomy for malignancy through flank incision between January 1, 2008, and June 30, 2011. We excluded patients who underwent tumor thrombectomy, used sustained-release opioids, or had general anesthesia supplemented by epidural analgesia. Patients were grouped into "spinal" (intrathecal opioid injection for postoperative analgesia) versus "general anesthetic" group, and "early" discharge group (within 3 postoperative days) versus "late" group. Association between demographics, patient physical status, anesthetic techniques, and surgical complexity and hospital stay were analyzed using multivariable logistic regression analysis. Of 380 patients, 158 (41.6%) were discharged "early" and 151 (39.7%) were "spinal" cases. Both spinal and early discharge groups had better postoperative pain control and used less postoperative systemic opioids. Spinal analgesia was associated with early hospital discharge, odds ratio 1.52, (95% confidence interval 1.00-2.30), P = 0.05, but in adjusted analysis was no longer associated with early discharge, 1.16 (0.73-1.86), P = 0.52. Early discharge was associated with calendar year, with more recent years being associated with early discharge. Spinal analgesia combined with general anesthesia was associated with improved postoperative pain control during the 1(st) postoperative day, but not with shorter hospital stay following partial nephrectomy. Therefore, unaccounted practice changes that occurred during more recent times affected hospital stay.

    Full Text Available Urinary tract infection (UTI is one of the commonest medical problems in children. It can distress the child and may cause kidney damage. Prompt diagnosis and effective treatment can prevent complications in the child. But treatment of UTI in children has now become a challenge due to the emergence of multidrug resistant bacteria. Aims & Objectives: To know the bacteriological profile and susceptibility pattern of urinary tract infections in children and to know the prevalence of multidrug resistant uropathogens. Materials & Methods: A retrospective analysis was done on all paediatric urine samples for a period of one year. A total of 1581 samples were included in the study. Antimicrobial susceptibility testing was done on samples showing significant growth by Kirby-Bauer disc diffusion method. Statistical analysis: Prevalence and pattern were analyzed using proportions and percentages. Results: E.coli was the most predominant organism (56% causing UTI in children followed by Klebsiella sp (17%. Fifty three percent of gram negative organisms isolated from children were found to be multidrug resistant. Majority of E. coli isolates were found to be highly resistant to Ampicillin (91% and Cotrimoxazole (82% and highly sensitive to Imipenem (99% and Amikacin (93%. Conclusion: Paediatric UTI was common in children less than 5 years of age. Gram negative bacteria (E. coli and Klebsiella sp were more common than gram positive bacteria. Our study revealed that multidrug resistance was higher in E.coli.

    We performed a retrospective analysis of commercial drivers to clarify the background of incidents of sudden illness while driving. The analysis used reports submitted by employers to the Japan Ministry of Land, Infrastructure, Transport, and Tourism regarding commercial drivers who had been ordered to stop driving owing to health problems. Of 211 cases with an average work history of 15.2 years, there were 88 bus drivers, 70 taxi drivers, and 53 truck drivers, 36.0% of who had died as a result of their disease. Among taxi and truck drivers, more than 70% of incidents were due to cardiac, aortic, and cerebrovascular disease. More than 80% of these were unable to avoid traffic accidents caused by sudden illness. However, among bus drivers, cardiac, aortic, and cerebrovascular disease accounted for only 23.5% of incidents, and accidents were avoided in more than half of the cases. The duration between starting work and the incident time was significantly shorter among bus drivers [mean 3.3 hours, standard deviation (SD) 3.1] than taxi (7.7 hours, SD 5.8) and truck (7.2 hours, SD 6.3) drivers (Pprevent disabling events while driving. As a precaution, physicians should advise commercial drivers to stop driving as soon as they detect slight discomfort. To prevent accidents, more assertive health promotion aimed at professional drivers is needed.

    2017-01-01

    Background As for all individuals, the Internet is important in the everyday life of older adults. Research on older adults’ use of the Internet has merely focused on users versus nonusers and consequences of Internet use and nonuse. Older adults are a heterogeneous group, which may implicate that their use of the Internet is diverse as well. Older adults can use the Internet for different activities, and this usage can be of influence on benefits the Internet can have for them. Objective The aim of this paper was to describe the diversity or heterogeneity in the activities for which older adults use the Internet and determine whether diversity is related to social or health-related variables. Methods We used data of a national representative Internet panel in the Netherlands. Panel members aged 65 years and older and who have access to and use the Internet were selected (N=1418). We conducted a latent class analysis based on the Internet activities that panel members reported to spend time on. Second, we described the identified clusters with descriptive statistics and compared the clusters using analysis of variance (ANOVA) and chi-square tests. Results Four clusters were distinguished. Cluster 1 was labeled as the “practical users” (36.88%, n=523). These respondents mainly used the Internet for practical and financial purposes such as searching for information, comparing products, and banking. Respondents in Cluster 2, the “minimizers” (32.23%, n=457), reported lowest frequency on most Internet activities, are older (mean age 73 years), and spent the smallest time on the Internet. Cluster 3 was labeled as the “maximizers” (17.77%, n=252); these respondents used the Internet for various activities, spent most time on the Internet, and were relatively younger (mean age below 70 years). Respondents in Cluster 4, the “social users,” mainly used the Internet for social and leisure-related activities such as gaming and social network sites. The

    Experience curves are useful for understanding technology development and can aid in the design and analysis of market transformation programs. Here, we employ a novel approach to create experience curves, to examine both global and North American compact fluorescent lamp (CFL) data for the years 1990–2007. We move away from the prevailing method of fitting a single, constant, exponential curve to data and instead search for break points where changes in the learning rate may have occurred. Our analysis suggests a learning rate of approximately 21% for the period of 1990–1997, and 51% and 79% in global and North American datasets, respectively, after 1998. We use price data for this analysis; therefore our learning rates encompass developments beyond typical “learning by doing”, including supply chain impacts such as market competition. We examine correlations between North American learning rates and the initiation of new programs, abrupt technological advances, and economic and political events, and find an increased learning rate associated with design advancements and federal standards programs. Our findings support the use of segmented experience curves for retrospective and prospective technology analysis, and may imply that investments in technology programs have contributed to an increase of the CFL learning rate. - Highlights: • We develop a segmented regression technique to estimate historical CFL learning curves. • CFL experience curves do not have a constant learning rate. • CFLs exhibited a learning rate of approximately 21% from 1990 to 1997. • The CFL learning rate significantly increased after 1998. • Increased CFL learning rate is correlated to technology deployment programs.

    This study investigated some aspects of breeding management in the Italian Heavy Draught Horse breed, aiming at improving its efficiency at stud farm level. A first aim was to evaluate the risk of unsuccessful reproduction in mares after an early (3 years) or normal (4 years) age at first foaling, in interaction with different stud rearing systems. A second objective was the examination of the mean time length in which young 2-year-old stallions maintain a genetic superiority on older proven stallions, identifying a 'genetic lifespan' in which young stallions can be safely used for reducing the cost of services. Reproductive performance at first and second foaling of 1513 mares were used. Mares had a normal first foal at 3 (n = 745) or 4 years of age (n = 768) in stud farms on the basis of stable (n = 488), feral (n = 345) or semi-feral (n = 680) rearing systems. Logistic regression analysis was performed by modeling the risk of unsuccessful reproduction in the subsequent season (i.e., results at second foaling), as affected by the interaction of age at first foaling × rearing system (six classes). Genetic lifespan of young stallions was estimated by regressing the least square means from a mixed model analysis for repeated measures of individual differences in 'total merit' estimated breeding values (EBVs) between young stallions (mean no. of 45/year) and the mean EBV of all proven stallions in a given year of genetic evaluation (mean no. of 483/year). Young stallions born between 1999 and 2005 were used, following each generation (i.e., birth year) from 2 to 7 subsequent yearly genetic evaluations. In comparison with the best reproductive success of second foaling at 4 years in stable systems, the greatest risk of unsuccessful reproduction was at 3 years in feral (+167%) and 3 years in semi-feral conditions (+91%). Young stallions showed a 0.50 s.d. greater EBV at the first evaluation than proven stallions, with a mean annual decrease in EBV of 0.07 s.d./year on

    Introduction Comprehensive studies on the relationship between patient demographics and subsequent treatment and disposition at a single mass-gathering event are lacking. The Sydney Royal Easter Show (SRES; Sydney Olympic Park, New South Wales, Australia) is an annual, 14-day, agricultural mass-gathering event occurring around the Easter weekend, attracting more than 800,000 patrons per year. In this study, patient records from the SRES were analyzed to examine relationships between weather, crowd size, day of week, and demographics on treatment and disposition. This information would help to predict factors affecting patient treatment and disposition to guide ongoing training of first responders and to evaluate the appropriateness of staffing skills mix at future events. Hypothesis Patient demographics, environmental factors, and attendance would influence the nature and severity of presentations at the SRES, which would influence staffing requirements. A retrospective analysis of 4,141 patient record forms was performed for patients who presented to St John Ambulance (Australian Capital Territory, Australia) at the SRES between 2012 and 2014 inclusive. Presentation type was classified using a previously published minimum data set. Data on weather and crowd size were obtained from the Australian Bureau of Meteorology (Melbourne, Victoria, Australia) and the SRES, respectively. Statistical analyses were performed using SPSS v22 (IBM; Armonk, New York USA). Between 2012 to 2014, over 2.5 million people attended the SRES with 4,141 patients treated onsite. As expected, the majority of presentations were injuries (49%) and illnesses (46%). Although patient demographics and presentation types did not change over time, the duration of treatment increased. A higher proportion of patients were discharged to hospital or home compared to the proportion of patients discharged back to the event. Patients from rural/regional locations (accounting for 15% of all patients) were

    Older adults with disability might have been increasing due to the rapid aging of society. Many studies showed that physical activity is an essential part for improving quality of life in later lives. Regular physical activity is an efficient means that has roles of primary prevention and secondary prevention. However, there were few studies regarding older adults with disability and physical activity participation. The purpose of this current study was to investigate restriction factors to regularly participate older adults with disability in physical activity by employing keyword network analysis. Two hundred twenty-nine older adults with disability who were over 65 including aging with disability and disability with aging in type of physical disability and brain lesions defined by disabled person welfare law partook in the open questionnaire assessing barriers to participate in physical activity. The results showed that the keyword the most often used was 'Traffic' which was total of 21 times (3.47%) and the same proportion as in the 'personal' and 'economical'. Exercise was considered the most central keyword for participating in physical activity and keywords such as facility, physical activity, disabled, program, transportation, gym, discomfort, opportunity, and leisure activity were associated with exercise. In conclusion, it is necessary to educate older persons with disability about a true meaning of physical activity and providing more physical activity opportunities and decreasing inconvenience should be systematically structured in Korea.

    Older adults with heart failure use strategies to cope with the constraining barriers impeding medication management. Strategies are behavioral adaptations that allow goal achievement despite these constraining conditions. When strategies do not exist, are ineffective or maladaptive, medication performance and health outcomes are at risk. While constraints to medication adherence are described in literature, strategies used by patients to manage medications are less well-described or understood. Guided by cognitive engineering concepts, the aim of this study was to describe and analyze the strategies used by older adults with heart failure to achieve their medication management goals. This mixed methods study employed an empirical strategies analysis method to elicit medication management strategies used by older adults with heart failure. Observation and interview data collected from 61 older adults with heart failure and 31 caregivers were analyzed using qualitative content analysis to derive categories, patterns and themes within and across cases. Data derived thematic sub-categories described planned and ad hoc methods of strategic adaptations. Stable strategies proactively adjusted the medication management process, environment, or the patients themselves. Patients applied situational strategies (planned or ad hoc) to irregular or unexpected situations. Medication non-adherence was a strategy employed when life goals conflicted with medication adherence. The health system was a source of constraints without providing commensurate strategies. Patients strived to control their medication system and achieve goals using adaptive strategies. Future patient self-mangement research can benefit from methods and theories used to study professional work, such as strategies analysis.

    Volumetric-modulated arc therapy (VMAT) is now widely used clinically, as it is capable of delivering a highly conformal dose distribution in a short time interval. We retrospectively analyzed patient-specific quality assurance (QA) of VMAT and examined the relationships between the planning parameters and the QA results. A total of 118 clinical VMAT cases underwent pretreatment QA. All plans had 3-dimensional diode array measurements, and 69 also had ion chamber measurements. Dose distribution and isocenter point dose were evaluated by comparing the measurements and the treatment planning system (TPS) calculations. In addition, the relationship between QA results and several planning parameters, such as dose level, control points (CPs), monitor units (MUs), average field width, and average leaf travel, were also analyzed. For delivered dose distribution, a gamma analysis passing rate greater than 90% was obtained for all plans and greater than 95% for 100 of 118 plans with the 3%/3-mm criteria. The difference (mean ± standard deviation) between the point doses measured by the ion chamber and those calculated by TPS was 0.9% ± 2.0% for all plans. For all cancer sites, nasopharyngeal carcinoma and gastric cancer have the lowest and highest average passing rates, respectively. From multivariate linear regression analysis, the dose level (p = 0.001) and the average leaf travel (p < 0.001) showed negative correlations with the passing rate, and the average field width (p = 0.003) showed a positive correlation with the passing rate, all indicating a correlation between the passing rate and the plan complexity. No statistically significant correlation was found between MU or CP and the passing rate. Analysis of the results of dosimetric pretreatment measurements as a function of VMAT plan parameters can provide important information to guide the plan parameter setting and optimization in TPS

The Micromedex Drug-Reax® system was used to screen patient profiles for pDDIs, and IBM SPSS version 20 was used to carry out statistical analysis.Results: We evaluated 209 medical charts and found pDDIs in nearly 78.5% CKD patients. Overall, 541 pDDIs were observed, of which, nearly 60.8% patients had moderate, 41.1% had minor, 27.8% had major, and 13.4% had contraindicated interactions. Among those interactions, 49.4% had good evidence, 44.0% had fair, 6.3% had excellent evidence, and 35.5% interactions had delayed onset of action. The potential adverse outcomes of pDDIs included postural hypotension, QT prolongation, ceftriaxone–calcium precipitation, cardiac arrhythmias, and reduction in therapeutic effectiveness. The occurrence of pDDIs was found strongly associated with the age of <60 years, number of prescribed medicines ≥5, hypertension, and the lengthy hospitalization of patients.Conclusion: The occurrence of pDDIs was high in CKD patients. It was observed that CKD patients with an older age, higher number of prescribed medicines, lengthy hospitalization, and hypertension were at

    Extra physiotherapy has been associated with better outcomes in hospitalized patients, but this remains an under-researched area in geriatric medicine wards. We retrospectively studied the association between average physiotherapy frequency and outcomes in hospitalized geriatric patients. High frequency physiotherapy (HFP) was defined as ≥0.5 contacts/day. Of 358 eligible patients, 131 (36.6%) received low, and 227 (63.4%) HFP. Functional improvement (discharge versus admission) in the modifi...

    Full Text Available Objective: To compare pre- and post-therapy symptom scores reported on the National Institute of Health Chronic Prostatitis Symptom Index (NIHCPSI after trans-rectal antibiotic injections therapy for men suffering from chronic prostatitis. Materials and methods: Retrospective analysis of NIHCPSI symptom scores obtained from chart reviews of 77 treated males suffering from chronic prostatitis before and after trans rectal injections for the treatment of chronic prostatitis. Results: Most patients reported a 40% to 60% improvement in symptom scores. In subgroups comparing scores in patients with less than 5 injections, the improvement was less than in patients who received 10 or more injections. Patients’ responses after a shorter (3 months follow up showed better pain scores than patient’s scores after longer, over one-year or more, follow- up periods. Conclusion: Our findings show that direct antibiotic injection for chronic prostatitis is a viable addition to standard therapies. Improvements in symptom scores are long lasting. Discomfort is minimal and side effects are rare and avoidable

    Leiomyosarcoma is a common subtype of soft tissue sarcoma originating from smooth muscle. We evaluated the clinical course and treatment outcome of patients with metastatic leiomyosarcoma. We retrospectively reviewed the records of patients at the University Hospitals Leuven. We identified 122 patients with metastatic leiomyosarcoma, 77 female, median age 59.5 years. Most patients developed leiomyosarcoma in the extremities (35%), the uterus (20%) or the abdomen (19%); 69% developed metachronous metastasis, 31% had synchronous metastatic disease. Most patients (74%) received palliative systemic therapy. The most common first-line treatments were doxorubicin (n = 47) and an anthracycline combined with an alkylator (n = 28). The objective response rate to first-line palliative systemic therapy was 20% and the median progression-free survival was 4.9 months (range 0.1-17.1). The median survival from diagnosis of metastasis was 20.5 months (range 0.4-126.9). On multivariate analysis, metachronous disease, no progressive disease as best response to first-line treatment, the possibility of metastasectomy with curative intent and use of palliative radiotherapy were indicators for better survival. The prognosis of patients with metastatic leiomyosarcoma is limited and objective responses to first-line systemic therapy are rare. The treatment of metastatic leiomyosarcoma remains an unmet medical need. © 2018 S. Karger GmbH, Freiburg.

    Postoperative ileus (POI) is an important factor prolonging the length of hospital stay following colorectal surgery. We retrospectively explored whether there is a clinically relevant association between intraoperative hypothermia and POI in patients who underwent laparoscopic colorectal surgery for malignancy within the setting of an enhanced recovery after surgery (ERAS) program between April 2016 and January 2017 at our institution. In total, 637 patients were analyzed, of whom 122 (19.2%) developed clinically and radiologically diagnosed POI. Overall, 530 (83.2%) patients experienced intraoperative hypothermia. Although the mean lowest core temperature was lower in patients with POI than those without POI (35.3 ± 0.5°C vs. 35.5 ± 0.5°C, P = 0.004), the independence of intraoperative hypothermia was not confirmed based on multivariate logistic regression analysis. In addition to three variables (high age-adjusted Charlson comorbidity index score, long duration of surgery, high maximum pain score during the first 3 days postoperatively), cumulative dose of rescue opioids used during the first 3 days postoperatively was identified as an independent risk factor of POI (odds ratio = 1.027 for each 1-morphine equivalent [mg] increase, 95% confidence interval = 1.014-1.040, P POI within an ERAS pathway, in which items other than thermal measures might offset its negative impact on POI. However, as it was associated with delayed discharge from the hospital, intraoperative maintenance of normothermia is still needed.

    Antimicrobial resistance has become an important concern in veterinary medicine. The aim of this study was to describe the rate of antimicrobial resistance in common equine pathogens and to determine the occurrence of multidrug-resistant isolates. A retrospective analysis of all susceptibility testing results from bacterial pathogens cultured from horses at the University of Zurich Equine Hospital (2012-2015) was performed. Strains exhibiting resistance to 3 or more antimicrobial categories were defined as multidrug-resistant. Susceptibility results from 303 bacterial pathogens were analyzed, most commonly Escherichia coli (60/303, 20%) and Staphylococcus aureus (40/303, 13%). High rates of acquired resistance against commonly used antimicrobials were found in most of the frequently isolated equine pathogens. The highest rate of multidrug resistance was found in isolates of Acinetobacter baumannii (23/24, 96%), followed by Enterobacter cloacae complex (24/28, 86%) and Escherichia coli (48/60, 80%). Overall, 60% of Escherichia coli isolates were phenotypically ESBL-producing and 68% of Staphylococcus spp. were phenotypically methicillin-resistant. High rates of acquired antimicrobial resistance towards commonly used antibiotics are concerning and underline the importance of individual bacteriological and antimicrobial susceptibility testing to guide antimicrobial therapy. Minimizing and optimizing antimicrobial therapy in horses is needed.

    We used stable isotope analysis to investigate the foraging ecology of coastal bottlenose dolphins (Tursiops truncatus) in relation to a series of anthropogenic disturbances. We first demonstrated that stable isotopes are a faithful indicator of habitat use by comparing muscle isotope values to behavioral foraging data from the same individuals. δ13C values increased, while δ34S and δ15N values decreased with the percentage of feeding observations in seagrass habitat. We then utilized stable isotope values of muscle to assess temporal variation in foraging habitat from 1991 to 2010 and collagen from tooth crown tips to assess the time period 1944 to 2007. From 1991 to 2010, δ13C values of muscle decreased while δ34S values increased indicating reduced utilization of seagrass habitat. From 1944 to 1989 δ13C values of the crown tip declined significantly, likely due to a reduction in the coverage of seagrass habitat and δ15N values significantly increased, a trend we attribute to nutrient loading from a rapidly increasing human population. Our results demonstrate the utility of using marine mammal foraging habits to retrospectively assess the extent to which anthropogenic disturbance impacts coastal food webs.

    A retrospective analysis was performed of 51 patients with locoregional recurrence of endometrial carcinoma, treated by radiotherapy between 1959 and 1986. There were 17 patients (33%) with isolated vaginal recurrence, 12 patients (24%) with vaginal recurrence with pelvic extension, 7 patients (14%) with pelvic recurrence only, and 15 patients (29%) with simultaneous locoregional and distant failure. Eighty percent of the recurrences occurred within 3.5 years from primary treatment; time to relapse was shorter in patients with advanced-stage, high-grade malignancy at original diagnosis. Locoregional control was achieved in 18 patients (35%). Complete tumor regression in the vagina, irrespective of extravaginal pelvic disease status or distant metastasis, occurred in 28 of 34 patients with vaginal involvement (82%). The 5- and 10-year overall actuarial survivals for all patients were 18 and 12.5%, respectively. The 5- and 10-year progression-free survivals of patients with isolated vaginal recurrences were 40% and 29%, respectively; the 5-year progression-free survival of patients with vaginal recurrence with pelvic extension was 20%. There were no survivors beyond 1.5 years among patients with pelvic recurrence (p = 0.02). All patients with simultaneous locoregional and distant failure were dead by 3.5 years. Stage at original diagnosis, time to relapse from primary treatment, histologic pattern, and grade of malignancy were prognosticators of survival. Five patients (10%) developed a total of ten radiation-related sequelae

    Heart disease is difficult to detect clinically and it has been suggested that echocardiography should be available to all patients with possible cardiac symptoms or signs. To analyse the results of 2 years of open access echocardiography for the frequency of structural heart disease according to request. Retrospective database analysis in a teaching hospital open access echocardiography service. Reports of all open access transthoracic echocardiograms between January 2011 and December 2012 were categorised as normal, having minor abnormalities, or significant abnormalities according to the indication. There were 2343 open access echocardiograms performed and there were significant abnormalities in 29%, predominantly valve disease (n = 304, 13%), LV systolic dysfunction (n = 179, 8%), aortic dilatation (n = 80, 3%), or pulmonary hypertension (n = 91, 4%). If echocardiography had been targeted at a high-risk group, 267 with valve disease would have been detected (compared to 127 with murmur alone) and 139 with LV systolic dysfunction (compared to 91 with suspected heart failure alone). Most GP practices requested fewer than 10 studies, but 6 practices requested over 70 studies. Open access echocardiograms are often abnormal but structural disease may not be suspected from the clinical request. Uptake by individual practices is patchy. A targeted expansion of echocardiography in patients with a high likelihood of disease is therefore likely to increase the detection of clinically important pathology.

    To identify consumer information needs about paracetamol, the most commonly used analgesic and antipyretic worldwide. Retrospective analysis of medicines questions from the public. Australian consumer medicines call centre. Callers to National Prescribing Service Medicines Line between September 2002 and June 2010 (n=123 217). Enquiry profile: demographics, enquiry type and concurrent medicines included in paracetamol calls; question themes derived from subset of call narratives. Paracetamol comprised part of the enquiry in 5.2% of calls (n=6367). The caller age distribution for paracetamol calls was skewed towards a younger cohort, with 45.2% made by those aged 25-44 vs 37.5% in 'rest of calls'. Significantly more paracetamol-related calls were made for a child (23.7%) compared with 'rest of calls' (12.7%, pConsumers have many concerns about the use of paracetamol that may be under-recognised by healthcare providers, with the nature of enquiries differing across life stages. These concerns are not adequately addressed by available consumer information. Improving access to targeted information about paracetamol would promote the safe and effective use of this common medicine. Published by the BMJ Publishing Group Limited.

    Urethroplasty is often successful for the treatment of male urethral stricture disease, but limited data exists on recurrence management. Our goal was to evaluate direct visual internal urethrotomy (DVIU) as a treatment option for isolated, recurrent strictures after urethroplasty. We retrospectively identified male patients who underwent urethroplasty from 1999 to 2013 and developed an isolated, recurrent stricture at the urethroplasty site treated with DVIU. Success was defined as lack of symptomatology and no subsequent intervention. Comparative analysis identified characteristics and stricture properties associated with success. A total of 436 urethroplasties were performed in 401 patients at our institution between 1999 and 2013. Stricture recurrence was noted in 64 (16%) patients. Of these, 47 (73%) underwent a DVIU. A total of 37 patients met inclusion criteria and underwent 50 DVIU procedures at the urethroplasty site. A single DVIU was successful in 13 of 37 patients (35%). A total of 4 of 6 patients required a second DVIU (67%). Overall, 17 of 43 (40%) of the total DVIUs were successful after urethroplasty. Success did not differ by age, stricture length or location, surgical technique, radiation history, prior urethroplasty or DVIU, time to failure, or etiology. Post-urethroplasty DVIU for isolated, recurrent strictures may be offered as a minimally invasive treatment option. Approximately 40% of patients were spared further intervention.

    The boarding of children and adolescents with identified psychiatric conditions at medical facilities has numerous negative effects on the patients and the systems that treat them. Efforts to minimize boarding times serves to increase patients' access to appropriate levels of care, redirect medical resources to patients who need them most, and reduce safety risks to people and property. This study explores the role Clinical Social Workers can play in facilitation of care and highlights the advantages of a coordinated data collection process facilitated by the effective use of the Electronic Medical Record. A retrospective chart analysis of 100 patients admitted to the Emergency department at a pediatric hospital in Central Florida was conducted for patients seen between 1 January 2015 and 30 June 2016. The data suggest key correlates that may impact the boarding times of pediatric patients presenting in a psychiatric crisis and the average duration of boarding time in hours (M = 5.11, SD = 2.07) was found to be significantly lower than prior published studies in the adult and pediatric literature. Discussion of these data implications on behavioral health practice is discussed.

    To assess agreement between parents' proxy reports of children's respiratory-related health service use and administrative data. A retrospective analysis of statistical agreement between clinical and claims data for reports of physician visits, emergency department (ED) visits, and hospitalizations in 545 asthmatic children recruited from sites in the greater Toronto area was conducted. Health services use data were extracted from the Ontario Health Insurance Plan and Canadian Institute for Health Information databases for each child for the interval coinciding with the proxy report for each health service type. Agreement between administrative data and respondent reports (n=545) was substantial for hospitalizations in the past year (kappa=0.80 [0.74, 0.86]), moderate for ED visits in the past year (kappa=0.60 [0.53, 0.67]), and slight for physician visits (kappa=0.13 [0.00, 0.27]) in the past 6 months. Income, parent's education, and child quality-of-life symptom scores did not affect agreement. Agreement for ED visits was significantly higher (Pasthma attack in the past 6 months (kappa=0.61 [0.54, 0.68]) compared to children who did not (kappa=0.25 [0.00, 0.59]). Parents of asthmatic children are reliable reporters of their child's respiratory-related urgent health services utilization.

    Objective. We compared the treatments of uterine carcinosarcoma at our institution and evaluated their impact on survival. Methods. A retrospective analysis was performed on 60 eligible patients with carcinosarcoma limited to the pelvis. Subjects were divided into four categories: surgery, surgery plus chemotherapy, surgery plus radiation therapy, and a combination of surgery, chemotherapy, and RT. The most commonly used chemotherapy was cisplatin and/or carboplatin and taxol. Radiotherapy included external beam radiation therapy (EBRT) alone or with high dose rate (HDR) brachytherapy or HDR brachytherapy alone. Survival probability data were computed using the Kaplan-Meier method. The differences between groups were compared using the log-rank test. Results. The combination of surgery and radiation therapy with or without chemotherapy is seen to improve overall survival (OS) compared to surgery alone (Ρ =0.044 and Ρ =0.028 resp.). Brachytherapy involving three HDR vaginal cylinder fractions shows an equally effective reduction in local recurrence compared to EBRT. Conclusion. Our study of a relatively large number of carcinosarcoma patients suggests that adjuvant radiation therapy improves OS compared to surgery alone. Brachytherapy with 3 HDR vaginal cylinder fractions is preferred because of its time-saving, better tolerance, low toxicity and equivalent OS, and local control compared to EBRT.

    The purpose of this study was to determine clinical and ultrasonographic characteristics of male breast tumors. The medical records of male patients with breast lesions were retrieved from an electronic medical record database and a pathology database and retrospectively reviewed. A total of 112 men (125 breast masses) with preoperative breast ultrasonography (US) were included (median age, 59.50 years; age range, 15-96 years). Data extracted included patient age, if the lesions were bilateral, palpable, and tender, and the presence of nipple discharge. Breast lesion features on static US images were reviewed by three experienced radiologists without knowledge of physical examination or pathology results, original breast US image interpretations, or surgical outcomes. The US features were documented according to the BI-RADS (Breast Imaging-Reporting and Data System) US lexicons. A forth radiologist compiled the data for analysis. Of the 125 breast masses, palpable tender lumps and bilateral synchronous masses were more likely to be benign than malignant (both, 100% vs 0%, P nipples were common in malignant lesions (P nipple, irregular shape, the presence of an echogenic halo, predominantly internal vascularity, and rich color flow signal on color Doppler ultrasound were significantly related to malignancy (all, P < 0.05). An echogenic halo and the presence of rich color flow signal were independent predictors of malignancy. Specific clinical and US characteristics of male breast tumors may help guide treatment, and determine if surgery or conservative treatment is preferable.

    Lipoprotein apheresis (LA) has proven to be an effective, safe and life-saving therapy. Vascular access is needed to facilitate this treatment but has recognised complications. Despite consistency in treatment indication and duration there are no guidelines in place. The aim of this study is to characterise vascular access practice at the UK's largest LA centre and forward suggestions for future approaches. A retrospective analysis of vascular access strategies was undertaken in all patients who received LA treatment in the low-density lipoprotein (LDL) Apheresis Unit at Harefield Hospital (Middlesex, UK) from November 2000 to March 2016. Fifty-three former and current patients underwent 4260 LA treatments. Peripheral vein cannulation represented 79% of initial vascular access strategies with arteriovenous (AV) fistula use accounting for 15%. Last used method of vascular access was peripheral vein cannulation in 57% versus AV fistula in 32%. Total AV fistula failure rate was 37%. Peripheral vein cannulation remains the most common method to facilitate LA. Practice trends indicate a move towards AV fistula creation; the favoured approach receiving support from the expert body in this area. AV fistula failure rate is high and of great concern, therefore we suggest the implementation of upper limb ultrasound vascular mapping in all patients who meet treatment eligibility criteria. We encourage close ties between apheresis units and specialist surgical centres to facilitate patient counselling and monitoring. Further prospective data regarding fistula failure is needed in this expanding treatment field.

    The Morse Fall Scale is used in several care settings for fall risk assessment and supports the implementation of preventive nursing interventions. Our work aims to analyze the Morse Fall Scale scores of Portuguese hospitalized adult patients in association with their characteristics, diagnoses and length of stay. Retrospective cohort analysis of Morse Fall Scale scores of 8356 patients hospitalized during 2012. Data were associated to age, gender, type of admission, specialty units, length of stay, patient discharge, and ICD-9 diagnosis. Elderly patients, female, with emergency service admission, at medical units and/or with longer length of stays were more frequently included in the risk group for falls. ICD-9 diagnosis may also be an important risk factor. More than a half of hospitalized patients had "medium" to "high" risk of falling during the length of stay, which determines the implementation and maintenance of protocoled preventive nursing interventions throughout hospitalization. There are several fall risk factors not assessed by Morse Fall Scale. There were no statistical differences in Morse Fall Scale score between the first and the last assessment.

    To evaluate the effect of written communication between an ophthalmologist and a primary care physician (PCP) on patient adherence to diabetic eye examination recommendations. In a retrospective cohort study of a multiethnic population at an urban ophthalmology center, records of all patients with diabetes and clinic visits between 2007 and 2010 were reviewed. Data collected included patient demographics, insurance status, hemoglobin A1C, severity of diabetic retinopathy, follow-up examinations, and written communication between a patient's ophthalmologist and PCP. Statistical analyses were performed to examine the relationship between physician communication and adherence to diabetic eye examination based on the American Academy of Ophthalmology-published recommendations. A total of 1,968 people with diabetes were included. Written communication from an ophthalmologist to a PCP was associated with increased adherence to follow-up eye examination recommendations (Odds Ratio: 1.49; 95% Confidence Interval: 1.16-1.92; P = 0.0018). Communication from a PCP to an ophthalmologist was also associated with increased adherence (Odds Ratio: 1.94; 95% Confidence Interval: 1.37-2.77; P = 0.0002). Multivariable analysis controlling for other factors associated with examination adherence confirmed that communication both to and from an ophthalmologist was independently and significantly associated with increased follow-up adherence. Patients with communication between ophthalmologists and PCPs are more likely to adhere to diabetic eye examinations.

    Due to the inherent imperfections in the imaging process, fluorescence microscopy images often suffer from spurious intensity variations, which is usually referred to as intensity inhomogeneity, intensity non uniformity, shading or bias field. In this paper, a retrospective shading correction method for fluorescence microscopy Escherichia coli (E. Coli) images is proposed based on segmentation result. Segmentation and shading correction are coupled together, so we iteratively correct the shading effects based on segmentation result and refine the segmentation by segmenting the image after shading correction. A fluorescence microscopy E. Coli image can be segmented (based on its intensity value) into two classes: the background and the cells, where the intensity variation within each class is close to zero if there is no shading. Therefore, we make use of this characteristics to correct the shading in each iteration. Shading is mathematically modeled as a multiplicative component and an additive noise component. The additive component is removed by a denoising process, and the multiplicative component is estimated using a fast algorithm to minimize the intra-class intensity variation. We tested our method on synthetic images and real fluorescence E.coli images. It works well not only for visual inspection, but also for numerical evaluation. Our proposed method should be useful for further quantitative analysis especially for protein expression value comparison.

    Nutrition plays a very important role in the healthy and in the ill horse. Although research in this field clearly shows that incorrect nutritional practices may lead to severe pathologies, inappropriate feeding plans often continue to be used. A clinical nutrition counselling (CNC) service could thus be of great use to both horse owners and veterinarians. The aim of this study was to provide information on equine patients referred to the CNC service of the University of Turin and to provide standard dietary protocols as used in our Veterinary Teaching Hospital for the most common nutrition-related pathologies. The data were obtained by retrospective analysis of the nutritional records of referred equine patients. The data collected included information about anamnesis, nutritional assessment, current diet, referring person and follow-up of each patient. Sixty-one horses were included in the study. The majority were adult males. The most common breeds were the Italian Saddle Horse and the Friesian Horse. Old horses (>19 years) had a statistically lower BCS than brood mares or other adult horses (p equine gastric ulcer syndrome. All horses received first-cut meadow hay; 85% also ate concentrates.

    Mahatma Gandhi's views on relating the world of formal education to the world of work were developed first in his experimental `Tolstoy Farm' in South Africa. On his return to India, Gandhi insisted that a required manual labour component in the curriculum would help regenerate India's village economy, develop in India's children a deeper understanding of India's cultural roots, motivate children to relate `book learning' to life in society, and destroy invidious caste distinctions. The major proposals and suggestions in Gandhi's writing will be discussed in the context of his hopes for using schooling as an agent of progress in India. Mao Ze-Dong's views, on the other hand, were developed in the context of his Yenan experience in the 1930s, i.e. the decision to consolidate a power base in the interior of China before waging a class war against the landlords and capitalists of China. Mao's views were also, to some extent, rooted in the Chinese reality of stagnant, poverty-stricken rural areas. But, Mao's writings indicate that Marxist hopes to relate theory and practice (as understood in dialectical materialism) and to ensure that everyone participated in mental as well as manual labour in a socialist society had led him to formulate his proposals. Both Gandhi's and Mao's views and proposals have been more or less abandoned in India and China respectively. The similar and dissimilar reasons which led to such a fate are examined in this retrospective analysis.

    To evaluate the premise that skeletal anchorage with SAS miniplates are highly successful and predictable for a range of complex orthodontic movements. This retrospective cross-sectional analysis consisted of 421 bone plates placed by one clinician in 163 patients (95 female, 68 male, mean age 29.4 years ± 12.02). Simple descriptive statistics were performed for a wide range of malocclusions and desired movements to obtain success, complication, and failure rates. The success rate of skeletal anchorage system miniplates was 98.6%, where approximately 40% of cases experienced mild complications. The most common complication was soft tissue inflammation, which was amenable to focused oral hygiene and antiseptic rinses. Infection occurred in approximately 15% of patients where there was a statistically significant correlation with poor oral hygiene. The most common movements were distalization and intrusion of teeth. More than a third of the cases involved complex movements in more than one plane of space. The success rate of skeletal anchorage system miniplates is high and predictable for a wide range of complex orthodontic movements.

    To evaluate the effect of Damon self-ligating and conventional bracket systems on buccal corridor widths and areas. A retrospective sample of consecutively treated patients using either conventional (CG, n  =  45) or Damon self-ligating (SL, n  =  39) brackets was analyzed to determine any differences in buccal corridor widths and areas both within and between groups. Pretreatment and posttreatment frontal photographs were transferred to Photoshop CC, standardized using intercanthal width, and linear and area measurements were performed with tools in Photoshop CC. Ratios were then calculated for statistical analysis. Relationships between arch widths and buccal corridors were also examined. There were no significant differences in the posttreatment intercanine or intermolar widths either within or between the CG and SL groups. There were no significant differences in any buccal corridor width or area measurement either within or between the CG and SL groups. There were strong correlations with the intercanine width and the corresponding buccal corridor smile width measurements. There was an inverse correlation with the buccal corridor area in relation to the canine and the total smile width. It is likely that posttreatment increases in arch width can be seen in patients treated with either a conventional bracket system or the Damon system. It is highly unlikely that there is any significant difference in buccal corridor width or area in patients treated with the Damon self-ligating system or a conventional bracket system.

    Omalizumab has been shown to be effective in chronic urticaria (CU) patients in numerous reports. However, it remains unknown whether there are specific phenotypes of CU that are more responsive to omalizumab therapy. We sought to identify CU phenotypes responsive to treatment with omalizumab by characterizing patients and their response patterns. A retrospective chart review analysis of refractory CU patients unresponsive to high-dose H1-blockers and immunomodulators and subsequently treated with omalizumab at the University of Wisconsin Allergy Clinic was performed with particular focus on their autoimmune characteristics, response to therapy, and dosing parameters. We analyzed 19 refractory CU patients (16 patients failed or had toxic side effects to immunomodulators) treated with omalizumab with an overall response rate of 89% (17/19). Of these 19 patients, 9 patients (47%) had a complete response, 8 patients (42%) had a partial response, and 2 patients (11%) had no response. In comparing the response patterns to omalizumab, we found no statistically significant differences among “autoimmune positive” versus “autoimmune negative” patients. No statistically significant differences in responses were observed when comparing demographic parameters including age, gender, IgE levels, or dosing regimen. Our study shows that omalizumab has robust efficacy in refractory CU patients regardless of their autoimmune status, age, gender, IgE levels, or dosing protocol. PMID:23998242

    Full Text Available Objective: To conduct a retrospective analysis of dengue cases in Kolkata, on the basis of presence of anti-dengue IgM in their sera and presence or absence of anti-dengue IgG and dengue specific Non structural 1 (NS1 antigen in each of the serum sample. Methods: Sample was tested quantitatively employing ELISA technique, using Biorad test kits, with a view to get a more comprehensive picture of dengue in an urban endemic area and also to evaluate individual cases. Results: This reconstructed study revealed that of those 91 dengue cases, 70.3% (64 and 29.7% (27 were suffering from secondary and primary dengue respectively, showing that number of secondary dengue cases were much more than that of primary dengue cases with a possibility of emergence of DHF. A small proportion of cases 18.7% (17 were reactive for NS1. The duration of fever in NS1 antigen positive cases varied between 5 and 7 days. Of 17 NS1 reactive cases, 10 (10.9% and 7 (7.7% were suffering from secondary and primary dengue respectively. Conclusions: Early detection of primary and secondary dengue cases would be facilitated by utilizing all three parameters (NS1 antigen, anti-dengue IgM and IgG helping to evaluate, monitor and treat a dengue case effectively.

    Successful utilization of SCT modalities often requires utilization of both red cell and platelet transfusions. In this retrospective evaluation of clinical factors affecting transplant engraftment and transfusion utilization at a single transplant center in 505 patients from 2005 through 2009, we found that graft type, donor type and the conditioning regimen intensity significantly affected both the neutrophil engraftment time (PSCT patients required an average of 6.2 red cell units, and 7.9 platelet transfusions in the first 100 days with a wide s.d. Among auto-SCT patients, 5% required neither RBC nor platelet transfusions. Some reduced-intensity transplants were also associated with no transfusion need, and in allogeneic transplants, conditioning regimen intensity was positively correlated with platelet transfusion events as assessed by multivariate analysis. Other patient characteristics such as gender, graft type, donor type, underlying disease and use of TBI were all independently associated with transfusion needs in SCT patients. Further studies are required to understand the means to minimize transfusions and potential related complications in SCT patients.

    Extubation failure is one of the most serious complications in extremely low birth weight infants (ELBWI) on mechanical ventilation therapy. We performed a 5-year retrospective analysis to realize the status of extubation failure in ELBWI. Extubation failure was defined as requirements of re-intubation within 72 hours after extubation. The extubation failure rate was 21% (29/138). The mean birth body weight was 808.3 +/- 140.4 gm. The mean gestational age was 25.8 +/- 1.2 wks. The incidence of chronic lung disease (CLD) in infants with extubation failure was 100% (29/29). Apnea of prematurity 49% (14/29) and post-extubation atelectasis 39% (11/29) were the most common reasons for reintubation. The major microbiology findings which correlated with nosocomial pneumonia in infants with extubation failure were Acinetobacter baumanni (21%), Klebsiella pneumonia (21%), Pseudomonas aeroginosa (14%), and Methicillin resistant staphylococcus aureus (14%). In conclusion, post-extubation atelectasis and apnea were the most common reasons for reintubation. ELBWI with extubation failure had higher incidences of post-extubation atelectasis, CLD, and nosocomial pneumonia. Further prospective studies are needed in order to clarify the appropriate extubation program for ELBWI and to prevent post-extubation atelectasis and nosocomial pneumonia.

    Although there are several case reports of wet wipe-associated contact dermatitis, the prevalence of wipes as a source of allergic contact dermatitis in larger populations and the responsible allergens are largely unknown. The aim of the study was to determine the prevalence of wet wipes as a source of contact allergy and the most commonly associated allergens in a North American tertiary referral patch test population. Data collected from 2011 to 2014 by the North American Contact Dermatitis Group was used to conduct a retrospective cross-sectional analysis of patient demographics and patch test results associated with the triple-digit source code for "wet wipe." Of the 9037 patients patch tested during the study period, 79 (0.9%) had a positive patch test reaction to an allergen identified with a wet wipe source. The most commonly associated allergens were preservatives, including the following: methylisothiazolinone (MI) (59.0%), methylchloroisothiazolinone (MCI)/MI (35.6%), bronopol (2-bromo-2-nitropropane-1,3-diol) (27.4%), and iodopropynyl butylcarbamate (12.3%). Fragrance (combined) represented 12.3%. Anal/genital dermatitis was 15 times more likely (P contact allergy had their contact allergens detected by the North American Contact Dermatitis Group screening series. Wet wipes are an important source of contact allergy. Preservatives are the main allergens, especially isothiazolinones.

    Full Text Available BACKGROUND ACL reconstruction is one of the commonest knee surgeries done. Young adults are the commonest patients; thus, this injury has a large impact on socioeconomic status of the family. The aim of the study is to study the outcome of arthroscopic ACL reconstruction with hamstring tendon graft. MATERIALS AND METHODS 50 patients following up in the OPD who had undergone ACL reconstruction with hamstring tendon graft are evaluated. Patients who had other lesions, such meniscal injuries or collateral injuries were discarded. These patients were evaluated by using Tegner and Lysholm score of 6 months, 12 months and 24 months. Settings- It is a retrospective analysis of the data collected from the patients who were opiated at Nair Hospital. RESULTS 90% of patients in the study were males. Mean age of the study population is 30.7 years. All the patients in the study had instability as a symptom, while 80% of them also had pain. Six months after surgery, according to Tegner and Lysholm score, 52% patients had good outcome, while 48% had fair outcome. At 2 years, 98% of study population had excellent outcome. CONCLUSION Arthroscopic ACL reconstruction with hamstring graft is an effective way of treating ACL tear.

    Fully human synthetic single-domain antibodies (sdAbs) are desirable therapeutic molecules but their development is a considerable challenge. Here, using a retrospective analysis of in-house historical data, we examined the parameters that impact the outcome of screening phage-displayed synthetic human sdAb libraries to discover antigen-specific binders. We found no evidence for a differential effect of domain type (V H or V L ), library randomization strategy, incorporation of a stabilizing disulfide linkage or sdAb display format (monovalent vs. multivalent) on the probability of obtaining any antigen-binding human sdAbs, instead finding that the success of library screens was primarily related to properties of target antigens, especially molecular mass. The solubility and binding affinity of sdAbs isolated from successful screens depended both on properties of the sdAb libraries (primarily domain type) and the target antigens. Taking attrition of sdAbs with major manufacturability concerns (aggregation; low expression) and sdAbs that do not recognize native cell-surface antigens as independent probabilities, we calculate the overall likelihood of obtaining ≥1 antigen-binding human sdAb from a single library-target screen as ~24%. Successful library-target screens should be expected to yield ~1.3 human sdAbs on average, each with average binding affinity of ~2 μM. Copyright © 2018 Elsevier B.V. All rights reserved.

    The study has focused on the retrospective analysis of cases of coexisting congenital aortic stenosis (AS) and pulmonary artery stenosis (PS) in dogs. The research included 5463 dogs which were referred for cardiological examination (including clinical examination, ECG and echocardiography) between 2004 and 2014. Aortic stenosis and PS stenosis were detected in 31 dogs. This complex defect was the most commonly diagnosed in Boxers - 7 dogs, other breeds were represented by: 4 cross-breed dogs, 2 Bichon Maltais, 3 Miniature Pinschers, 2 Bernese Mountain Dogs, 2 French Bulldogs, and individuals of following breeds: Bichon Frise, Bull Terrier, Czech Wolfdog, German Shepherd, Hairless Chinese Crested Dog, Miniature Schnauzer, Pug, Rottweiler, Samoyed, West Highland White Terrier and Yorkshire Terrier. In all the dogs, the murmurs could be heard, graded from 2 to 5 (on a scale of 1-6). Besides, in 9 cases other congenital defects were diagnosed: patent ductus arteriosus, mitral valve dysplasia, pulmonary or aortic valve regurgitation, tricuspid valve dysplasia, ventricular or atrial septal defect. The majority of the dogs suffered from pulmonary valvular stenosis (1 dog had supravalvular pulmonary artery stenosis) and subvalvular aortic stenosis (2 dogs had valvular aortic stenosis). Conclusions and clinical relevance - co-occurrence of AS and PS is the most common complex congenital heart defect. Boxer breed was predisposed to this complex defect. It was found that coexisting AS and PS is more common in male dogs and the degree of PS and AS was mostly similar.

    Introduction: In order for a diagnosis of Occupational Hearing Loss (BK-no. 2301) to be made certain criteria must be fulfilled to establish that the hearing loss is occupational in origin. This work compares 2 groups, those who fulfil the criteria (BKE) and those who do not (BKNE). Methods: A 100 consecutive reports ("Lärmgutachten BK-no. 2301") written by the authors were examined retrospectively. These recorded audiometric examination, an analysis of any tinnitus and noise exposure plus use of hearing protection. Pre- and post-noise exposure status together with an expert assessment of work limitations was made to produce a 7 point score. Results: 67% of the group fulfilled the conditions for occupational hearing loss (9% were entitled to compensation). In the BKE group 82% showed typical audiometric signs of noise damage with 75% of them fulfilling at least 6 criteria of occupational disease no. 2301. Tinnitus typical for noise exposure was found in 26%. Discussion: A 7 point score could be useful in the future as a method of helping distinguish hearing loss and tinnitus from occupational as opposed to other causes. © Georg Thieme Verlag KG Stuttgart · New York.

    A number of long-distance running events are held each year in the United States; the Army Ten Miler (ATM) is one such race held annually in Washington, DC. The purpose of the present study was to retrospectively analyze medical encounters for runners participating in the ATM from 1998 to 2004. Of the estimated 91,750 runners over the 6-year period, 73,100 participants finished the race and were included in the data analysis. Demographic and injury data were collected from medical records of participants who received medical care while participating in the ATM, and injury-related factors were assessed. The most common category of injury was musculoskeletal (44%), followed by medical-related problems (27%) and dermatological injuries (27%). Similar to marathon and ironman races, ATM injury rates correlate with race-day temperature and dew point. Overall, however, the injury rates observed at the ATM were relatively low compared to those reported for longer distance events. Finally, we detail the medical coverage provided at the ATM, as this coverage could be used as a guide for similarly distanced races.

    The aim of this study was to identify the incidence of upper gastrointestinal bleeding (UGIB) in the postprocedural period following transcatheter aortic valve replacement (TAVR). As TAVR moves into intermediate- and low-risk patients, it has become increasingly important to understand its extracardiac complications. The patient population undergoing TAVR have clinical and demographic characteristics that place them at significant risk of UGIB. Practical aspects of TAVR, including use of antithrombotic therapy, further increase risk of UGIB. A retrospective single-center evaluation of 841 patients who underwent TAVR between January 2005 and August 2014 was performed in conjunction with analysis of referral patterns to the gastroenterology service for UGIB at the same site. The overall risk of UGIB following TAVR was found to be 2.0% (n = 17/841). Additionally, the risk of UGIB in patients receiving triple antithrombotic therapy was found to be 10-fold greater than patients not receiving triple antithrombotic therapy (11.8% vs 1.0%). Endoscopy findings demonstrated five high-risk esophageal lesions including erosive esophageal ulcers, visible vessels at the GE junction, erosions at distal esophagus, and an actively bleeding esophageal ring that had been intubated through by the transesophageal echocardiography (TEE) probe. This large cohort study demonstrates that TAVR is associated with a moderate risk of severe UGIB. The results of this study suggest that patients on triple antithrombotic therapy are at highest risk for severe UGIB. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    To compare clinical outcomes and institutional costs of elective laparoscopic and open incisional hernia mesh repairs and to identify independent predictors of prolonged operative time and hospital length of stay (LOS). Retrospective observational cohort study on 269 consecutive patients who underwent elective incisional hernia mesh repair, laparoscopic group (N = 94) and open group (N = 175), between May 2004 and July 2014. Operative time was shorter in the laparoscopic versus open group (p costs were lower (p = 0.02). At Cox regression analysis adjusted for potential confounders, large wall defect (W3) and higher operative risk (ASA score 3-4) were associated with prolonged operative time, while midline hernia site was associated with increased hospital LOS. Open surgical approach was associated with prolongation of both operative time and LOS. Laparoscopic approach may be considered safely to all patients for incisional hernia repair, regardless of patients' characteristics (age, gender, BMI, ASA score, comorbidities) and size of the wall defect (W2-3), with the advantage of shorter operating time and hospital LOS that yields reduced total institutional costs. Patients with higher ASA score and large hernia defects are at risk of prolonged operative time, while an open approach is associated with longer duration of surgical operation and hospital LOS.

    The aim of this study was to evaluate 12 years of general practitioner (GP) use of open access MRI services at a single London teaching hospital. A retrospective analysis of reports from all GP requests for MRI scans between 1994 and 2005 was performed. The date, scanned body part, and requester details from 1798 scans requested by 209 individual GPs over a continuous 12-year period were recorded. All scans were then graded into four categories based on the severity of reported findings from normal to gross abnormality. Over the study period, GP requests as a percentage of the total (MRI) department workload remained low at approximately 2.6%. Spine, knee and brain requests constituted 86% (n = 1546) of requested scans. 48% (n = 868) of scans were reported as normal or minor degenerative changes only. 26% (n = 466) of scans demonstrated serious pathology that was likely to warrant hospital consultant referral. There was a wide range of scans requested per requester, from 1 to 240 over the period, with an average of 8.5 scans per GP. In conclusion, any department wishing to set up open access to MRI services for GPs could cover the majority of requests by offering spine, knee and brain imaging. The percentage of normal report rates for GP requests is comparable with previous studies of outpatient referrals. A large variation in requesting patterns between GPs suggests the need for increased communication between GPs and imaging departments to optimise use of the service.

    To discover if healthcare professionals working within an ED are able to make a diagnosis of female genital mutilation (FGM) in those patients who have previously undergone the procedure and report it as per UK law. A retrospective analysis of patients' notes who were assigned an FGM code during the period of May 2015 to August 2016. Single-centre, large UK major trauma centre offering a tertiary FGM clinic. Any woman coded during the study period as having undergone FGM. Number of FGM cases identified by the ED. Mean age, presenting complaint, discharge diagnosis, genitourinary exam and defibulation status. 34 patients were identified as having undergone FGM, 19 had previously attended ED and none had their FGM identified during their ED attendance. The age range of those identified was 23 to 40 years. None had undergone defibulation. This study demonstrates that the identification of FGM victims by an ED is very poor, and more work needs to be done to increase awareness of the subject by front-line staff. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available Background. The long-term efficacy of aldosterone-receptor antagonists (ARAs as add-on treatment in uncontrolled hypertension has not yet been reported. Methods. Data from 123 patients (21 with primary aldosteronism, 102 with essential hypertension with difficult-to-treat hypertension who received an ARA between May 2005 and September 2009 were analyzed retrospectively for their blood pressure (BP and biochemical response at first followup after start with ARA and the last follow-up available. Results. Systolic BP decreased by 22±20 and diastolic BP by 9.4±12 mmHg after a median treatment duration of 25 months. In patients that received treatment >5 years, SBP was 33±20 and DBP was 16 ± 13 mmHg lower than at baseline. Multivariate analysis revealed that baseline BP and follow-up duration were positively correlated with BP response. Conclusion. Add-on ARA treatment in difficult-to-treat hypertension results in a profound and sustained BP reduction.

    Little is known about the effectiveness of occlusion therapy in hospital settings. A retrospective analysis was conducted to assess modalities, outcome and hospital costs of children treated for amblyopia with patching in a UK clinic. Notes of 322 children with amblyopia discharged after occlusion treatment were selected consecutively and reviewed. Data collated included age at presentation, amblyopia type, visual acuity (VA; before/after occlusion and at discharge), number of prescribed hours of occlusion, duration of patching treatment, number of glasses prescribed and number of visits attended or failed to attend. Hospital treatment costs were estimated. Mixed amblyopes were prescribed the longest amount of patching (mean 2815 h over 23 months) followed by strabismic (1984 h) and anisometropic (1238 h) amblyopes. 319 amblyopes received glasses and five atropine treatment. The percentage of patients reaching VA of 6/12 was best in the anisometropic and strabismic groups (>75%) and worse in mixed amblyopia (64%). Average hospital costs were estimated at pound1365. Although the mean duration of treatment was long, involving many hospital visits, the visual outcome was variable, unsatisfactory (amblyopia treatment are needed, possibly by using educational/motivational intervention.

    Full Text Available Objective: The aim of the study is to analyze the general aspects of cases with carbon monoxide intoxication in order to improve the approach to future patients. Material and Methods: The hospital records of 84 children (mean age 4.71±2.64 years; 48 male, 36 female who had been admitted to Paediatric Emergency Department for carbon monoxide intoxication between October 2007 and February 2009, were retrospectively evaluated in a descriptive analysis.Results: The source of carbon monoxide intoxication was heaters, waterheaters and fi re in 82.1%, 7.1% and 6% of cases, respectively. There was a statistically signifi cant difference between the carboxyhemoglobin levels of the patients according to the clinical classifi cation (p<0.05. The intoxication caused by heaters was observed signifi cantly in November, December and January (p<0.001, between 16:00-24:00 hours (p<0.001 and among more than one member of a family (p<0.001. A medium level correlation was detected between the treatment approach and clinical classifi cation (r=0.50, p<0.001. Conclusion: Carbon monoxide intoxication, in the presented series, was found to develop accidentally; mostly in the Winter season; during night hours when the family members gathered together. The carboxyhemoglobin levels were appropriate with the developing clinical findings. Carboxyhemoglobin level solely was not enough for achieving the diagnosis and planning the treatment.

    Little information has been published in the literature regarding survival outcomes of patients with Ewing's sarcoma family tumors (ESFTs) of the spine. The purpose of this study is to explore factors that may affect the prognosis of patients with non-metastatic spinal ESFTs. A retrospective analysis of survival outcomes was performed in patients with non-metastatic spinal ESFTs. Univariate and multivariate analyses were employed to identify prognostic factors for recurrence and survival. Recurrence-free survival (RFS) and overall survival (OS) were defined as the date of surgery to the date of local relapse and death. Kaplan-Meier methods were applied to estimate RFS and OS. Log-rank test was used to analyze single factors for RFS and OS. Factors with p values ≤0.1 were subjected to multivariate analysis. A total of 63 patients with non-metastatic spinal ESFTs were included in this study. The mean follow-up period was 35.1 months (range 1-155). Postoperative recurrence was detected in 25 patients, and distant metastasis and death occurred in 22 and 36 patients respectively. The result of multivariate analysis suggested that age older than 25 years and neoadjuvant chemotherapy were favorable independent prognostic factors for RFS and OS. In addition, total en-bloc resection, postoperative chemotherapy, radiotherapy and non-distant metastasis were favorable independent prognostic factors for OS. Age older than 25 years and neoadjuvant chemotherapy are favorable prognostic factors for both RFS and OS. In addition, total en-bloc resection, postoperative chemotherapy, radiotherapy and non-distant metastasis are closely associated with favorable survival.

    This retrospective analysis was performed to evaluate osteolytic bone lesions of breast cancer in the thoracic and lumbar spine after radiotherapy (RT) in terms of stability using a validated scoring system. The stability of 157 osteolytic metastases, treated from January 2000 to January 2012, in 115 patients with breast cancer was evaluated retrospectively using the Taneichi score. Predictive factors for stability were analyzed and survival rates were calculated. Eighty-five (54 %) lesions were classified as unstable prior to RT. After 3 and 6 months, 109 (70 %) and 124 (79 %) lesions, respectively, were classified as stable. Thirty fractures were detected prior to RT, and after RT seven cases (4.5 %) with pathologic fractures were found within 6 months. None of the examined predictive factors showed significant correlation with stability 6 months after RT. After a median follow-up of 16.7 months, Kaplan-Meier estimates revealed an overall survival of 83 % after 5 years. The majority of patients showed an improved or unchanged stability of the involved vertebral bodies after 6 months. The patients showed only minor cancer-related morbidity during follow-up and reached comparably high survival rates. (orig.)

    Falls among older adults can cause serious morbidity and pose economic burdens on society. Older age is a known risk factor for falls and age has been shown to influence the effectiveness of fall prevention programs. To our knowledge, no studies have explicitly investigated whether cost-effectiveness of a multifactorial fall prevention intervention (the intervention) is influenced by age. This economic evaluation explores: 1) the cost-effectiveness of a multifactorial fall prevention intervention compared to usual care for community-dwelling adults ≥ 75 years at risk of falling in Canada; and 2) the influence of age on the cost-effectiveness of the intervention. Net benefit regression was used to examine the cost-effectiveness of the intervention with willingness-to-pay values ranging from $0-$50,000. Effects were measured as change in the number of falls, from baseline to 6-month follow-up. Costs were measured using a societal perspective. The cost-effectiveness analysis was conducted for both the total sample and by age subgroups (75-84 and 85+ years). For the total sample, the intervention was not economically attractive. However, the intervention was cost-effective at higher willingness-to-pay (WTP) (≥ $25,000) for adults 75-84 years and at lower WTP (cost-effectiveness of the intervention depends on age and decision makers' WTP to prevent falls. Understanding the influence of age on the cost-effectiveness of an intervention may help to target resources to those who benefit most. Retrospectively registered.

    low balance confidence is a major health problem among older adults restricting their participation in daily life. to determine what interventions are most effective in increasing balance confidence in older adults. systematic review with meta-analysis of randomised controlled trials including at least one continuous end point of balance confidence. Studies, including adults 60 years or older without a neurological condition, were included in our study. the standardised mean difference (SMD) of continuous end points of balance confidence was calculated to estimate the pooled effect size with random-effect models. Methodological quality of trials was assessed using the Physical Therapy Evidence Database (PEDro) Scale. thirty studies were included in this review and a meta-analysis was conducted for 24 studies. Interventions were pooled into exercise (n = 9 trials, 453 subjects), Tai Chi (n = 5 trials, 468 subjects), multifactorial intervention (n = 10 trials, 1,233 subjects). Low significant effects were found for exercise and multifactorial interventions (SMD 0.22-0.31) and medium (SMD 0.48) significant effects were found for Tai Chi. Tai chi interventions are the most beneficial in increasing the balance confidence of older adults.

    While most meningiomas are benign, aggressive meningiomas are associated with high levels of recurrence and mortality. A single institution’s Gamma Knife radiosurgical experience with atypical and malignant meningiomas is presented, stratified by the most recent WHO classification. Thirty-one patients with atypical and 4 patients with malignant meningiomas treated with Gamma Knife radiosurgery between July 2000 and July 2011 were retrospectively reviewed. All patients underwent prior surgical resection. Overall survival was the primary endpoint and rate of disease recurrence in the brain was a secondary endpoint. Patients who had previous radiotherapy or prior surgical resection were included. Kaplan-Meier and Cox proportional hazards models were used to estimate survival and identify factors predictive of recurrence and survival. Post-Gamma Knife recurrence was identified in 11 patients (31.4%) with a median overall survival of 36 months and progression-free survival of 25.8 months. Nine patients (25.7%) had died. Three-year overall survival (OS) and progression-free survival (PFS) rates were 78.0% and 65.0%, respectively. WHO grade II 3-year OS and PFS were 83.4% and 70.1%, while WHO grade III 3-year OS and PFS were 33.3% and 0%. Recurrence rate was significantly higher in patients with a prior history of benign meningioma, nuclear atypia, high mitotic rate, spontaneous necrosis, and WHO grade III diagnosis on univariate analysis; only WHO grade III diagnosis was significant on multivariate analysis. Overall survival was adversely affected in patients with WHO grade III diagnosis, prior history of benign meningioma, prior fractionated radiotherapy, larger tumor volume, and higher isocenter number on univariate analysis; WHO grade III diagnosis and larger treated tumor volume were significant on multivariate analysis. Atypical and anaplastic meningiomas remain difficult tumors to treat. WHO grade III diagnosis and treated tumor volume were significantly

    Despite growing interest in the therapeutic use of cannabis to manage chronic pain, only limited data that address these issues are available. In recent years, a number of nations have introduced specific laws to allow patients to use cannabis preparations to treat a variety of medical conditions. In 2015, the Italian government authorized the use of cannabis to treat several diseases, including chronic pain generally, spasticity in multiple sclerosis, cachexia and anorexia among AIDS and cancer patients, glaucoma, Tourette syndrome, and certain types of epilepsy. We present the first snapshot of the Italian experience with cannabis use for chronic pain over the initial year of its use. This is a retrospective case series analysis of all chronic pain patients treated with oral or vaporized cannabis in six hubs during the initial year following the approval of the new Italian law (December 2015 to November 2016). We evaluated routes of administration, types of cannabis products utilized, dosing, and effectiveness and safety of the treatment. As only one of the six centers has extensively used cannabinoids for intractable chronic pain (614 patients of 659), only the population from Azienda Ospedaliero Universitaria Pisana (Pisa) was considered. Cannabis tea was the primary mode of delivery, and in almost all cases, it was used in association with all the other pain treatments. Initial and follow-up cannabinoid concentrations were found to vary considerably. At initial follow-up, 76.2% of patients continued the treatment, and <15% stopped the treatment due to side effects (none of which were severe). We present the first analysis of Italian clinical practice of the use of cannabinoids for a large variety of chronic pain syndromes. From this initial snapshot, we determined that the treatment seems to be effective and safe, although more data and subsequent trials are needed to better investigate its ideal clinical indication.

    Pediatric breast reduction mammaplasty is a procedure commonly performed in children suffering from excess breast tissue, back pain, and social anxiety. Minimal information exists regarding demographics, epidemiology, and complications in adolescents. As health care reform progresses, investigating the socioeconomic and patient-related factors affecting cost and operative outcomes is essential. The Kids' Inpatient Database (KID) was used from 2000 to 2009. Patients with an International Classification of Diseases, 9th Revision code of macromastia and procedure code of reduction mammaplasty 20 and less were included. Demographic data, including age, sex, payer mix, and location, were collected. Significant independent variables associated with complications and duration of stay were identified with bivariate and multiple regression analysis. A total of 1,345 patients between the ages 12 and 20 were evaluated. The majority of patients were white (64%), from a zip code with greatest income (36%), and had private insurance (75%). Overall comorbidity and complication rates were 30% and 3.2%, respectively. Duration of stay was associated with race, income quartile, insurance type, having complications, and hospital type. African-American race, Medicaid, lower income, and private-investor owned hospitals were predictive of greater hospital charges. In this large retrospective database analysis, pediatric reduction mammaplasty had a relatively low early complication rate and short duration of stay. Complications, total charges, and duration of stay discrepancies were associated with race, location, and socioeconomic status. Although demonstrably safe, this is the first study demonstrating the negative effect of race and socioeconomic status on a completely elective procedure involving children. These results demonstrate the intricate association between socioeconomic and patient-related factors influencing overall outcomes in the pediatric population. Copyright © 2015

    Purpose: The purpose of this study is to retrospectively analyze the portal dosimetry based quality assurance of prostate VMAT plans. Methods: Our standard quality assurance of VMAT treatment plans are performed using EPID installed on Varian TrueBeam Linac. In our current study we analyzed 84 prostate pretreatment VMAT plans. All plans consisted of two arcs, 7800cGy in 39 fractions with a 6MV beam. For each of these VMAT plans, the measured fluence for each arc is compared with the reference fluence using gamma index analysis. Results: We have compared the gamma passing rates for three criteria; 3%/3mm, 2%/2mm and 1%/1mm. Out of 168 arcs measured, the number below the gamma passing rate 95% using the area, Field+1cm, are 0, 2, and 124 for 3%/3mm, 2%/2mm and 1%/1mm criteria respectively. Corresponding numbers for MLC CIAO are 0, 2, and 139 respectively. The average gamma passing rate for all arcs measured using Field+1cm are 99.9±0.4, 99.6±1.2, and 90.9±6.5 for 3%/3mm, 2%/2mm and 1%/1mm respectively. Similarly if the MLC CIAO area is analyzed, a passing rate of 99.9±0.2, 99.2±1.2 and 87.2±8.5 respectively was observed. The average of the maximum gamma was also found to increase with tighter criteria. Conclusion: Analysis of prostate VMAT quality assurance plans indicate that the gamma passing rate is sensitive to the criteria and the area analyzed.

    Tracheobronchial stents are inserted mainly in cases of malignant and benign airway stenosis. Further indications are esophago-tracheal fistulas, mediastinal fistulas and tracheomalacia. A retrospective analysis was conducted on patients' records, information provided by the general practitioners and relatives of the patients from July 1993 to December 2006 in the Department of Pneumology of the Heidehaus Hospital Hannover (since 6/05 Department of Pneumology and Internal Intensive Care Medicine, Oststadt-Heidehaus Hospital). During the observation period of 13 years a total of 269 stents (177 permanent, 92 temporary) were implanted in 207 patients (1.3 stents per patient). The vast majority of patients (173/207) suffered from an underlying malignancy. About half of the stents were deployed in the trachea. The median length of placement was 116 days in patients with malignancies and 313 days in patients with benign diseases. In about 40 % of the patients notable complications were observed which were directly or indirectly associated with the stents. These findings show the importance of a critical indication for stent implantation. In benign diseases a stent can remain for years inside the tracheobronchial system, if it is well tolerated in the beginning. In malignant diseases the result depends decisively on the stage of the tumour: has the stent been implanted before any other tumour therapy is started or is it an end-stage tumor with no other therapeutic option? In general, complications of stents occur quite frequently. The analysis of stent data leads to some aspects for the prevention of stent-related complications. There should be a strict indication and appropriate choice of stent material. Nevertheless, there remains an ethical dilemma in patients with end-stage disease as to whether to implant a stent or to do nothing against the tumor, because the benefit immediately after stent insertion vanishes with progression of the tumour, so causing extra

    Objectives The aim of this study was to compare the health care costs for patients using additional homeopathic treatment (homeopathy group) with the costs for those receiving usual care (control group). Methods Cost data provided by a large German statutory health insurance company were retrospectively analysed from the societal perspective (primary outcome) and from the statutory health insurance perspective. Patients in both groups were matched using a propensity score matching procedure based on socio-demographic variables as well as costs, number of hospital stays and sick leave days in the previous 12 months. Total cumulative costs over 18 months were compared between the groups with an analysis of covariance (adjusted for baseline costs) across diagnoses and for six specific diagnoses (depression, migraine, allergic rhinitis, asthma, atopic dermatitis, and headache). Results Data from 44,550 patients (67.3% females) were available for analysis. From the societal perspective, total costs after 18 months were higher in the homeopathy group (adj. mean: EUR 7,207.72 [95% CI 7,001.14–7,414.29]) than in the control group (EUR 5,857.56 [5,650.98–6,064.13]; phomeopathy EUR 3,698.00 [3,586.48–3,809.53] vs. control EUR 3,092.84 [2,981.31–3,204.37]) and outpatient care costs (homeopathy EUR 1,088.25 [1,073.90–1,102.59] vs. control EUR 867.87 [853.52–882.21]). Group differences decreased over time. For all diagnoses, costs were higher in the homeopathy group than in the control group, although this difference was not always statistically significant. Conclusion Compared with usual care, additional homeopathic treatment was associated with significantly higher costs. These analyses did not confirm previously observed cost savings resulting from the use of homeopathy in the health care system. PMID:26230412

    As NASA transitions from the Space Shuttle era into the next phase of space exploration, the need to ensure the capture, analysis, and application of its research and medical data is of greater urgency than at any other previous time. In this era of limited resources and challenging schedules, the Human Research Program (HRP) based at NASA s Johnson Space Center (JSC) recognizes the need to extract the greatest possible amount of information from the data already captured, as well as focus current and future research funding on addressing the HRP goal to provide human health and performance countermeasures, knowledge, technologies, and tools to enable safe, reliable, and productive human space exploration. To this end, the Science Management Office and the Medical Informatics and Health Care Systems Branch within the HRP and the Space Medicine Division have been working to make both research data and clinical data more accessible to the user community. The Life Sciences Data Archive (LSDA), the research repository housing data and information regarding the physiologic effects of microgravity, and the Lifetime Surveillance of Astronaut Health (LSAH-R), the clinical repository housing astronaut data, have joined forces to achieve this goal. The task of both repositories is to acquire, preserve, and distribute data and information both within the NASA community and to the science community at large. This is accomplished via the LSDA s public website (http://lsda.jsc.nasa.gov), which allows access to experiment descriptions including hardware, datasets, key personnel, mission descriptions and a mechanism for researchers to request additional data, research and clinical, that is not accessible from the public website. This will result in making the work of NASA and its partners available to the wider sciences community, both domestic and international. The desired outcome is the use of these data for knowledge discovery, retrospective analysis, and planning of future

    Prior research has shown that exposure to negative age-based stereotype threat (ST) can undermine older adults' memory performance. The objective of the current meta-analysis was to examine the reliability and magnitude of ST effects on older adults' episodic and working memory performance-two forms of memory that typically show the greatest age-related declines. In addition, we examined potential moderators of age-based ST including type of ST manipulation, type and timing of memory task, participant age and education level. A total of 23 samples for episodic memory and 15 samples for working memory were derived from 19 published and 4 unpublished articles and analyzed in two separate meta-analyses. Analyses revealed a reliable effect of ST on both older adults' episodic (d = 0.373) and working memory performance (d = 0.253). Interestingly, the age-based ST effect was only significant when blatant ST manipulations were used with episodic memory tasks or when subtle ST manipulations were used with working memory tasks. Moreover, within episodic memory, the ST effect only reached significance for recall but not cued-recall or recognition performance, and for immediate but not delayed tests of memory. Neither age nor level of education moderated the association between ST and older adults' memory performance. These results highlight the vulnerability of both older adults' episodic and working memory performance to age-based ST. When measuring older adults' memory performance in a research context, we must therefore be wary of exposing participants to common stereotypes about aging and memory. © The Author 2017.

    To describe the characteristics of communication practice in home care visits between older people (over 65 years old) and nurse assistants and to discuss the findings from a person-centered perspective. The older population is increasing worldwide, along with the need for healthcare services in the person's home. To achieve a high-quality care, person-centered communication is crucial. A descriptive design with a qualitative inductive approach was used. Fifteen audio recordings of naturally occurring conversations between 12 nurse assistants and 13 older people in Norway were analysed by qualitative content analysis. Four categories were revealed through analysis: (i) supporting older people's connection to everyday life; (ii) supporting older people's involvement in their own care; (iii) attention to older people's bodily and existential needs; and (iv) the impact of continuity and predictability on older people's well-being. The communication between the older people and the nurse assistants during home care visits was mainly task-oriented, but also related to the person. The older people were involved in the tasks to be carried out and humour was part of the communication. Greater attention was paid to bodily than existential needs. The communication was connected with the older people's everyday life in several ways. Time frames and interruptions concern the older people; hearing and speech impairments were a challenge to communication. To enhance person-centred communication, further studies are needed, especially intervention studies for healthcare professionals and students. Being responsive to older people's subjective experiences is important in meeting their needs in home care. Communication that addresses the need for trust and predictability is important for older people. Responding to existential needs require more attention. The home care setting has an impact on communication. © 2017 John Wiley & Sons Ltd.

    Full Text Available ObjectiveTo describe and analyze the clinical characteristics, laboratory data, management, and outcome of patients with onconeural antibody-associated disorders (OAAD and identify predictors for poor outcome.MethodsThis was a retrospective review of all patients with potential OAAD, who were hospitalized in Jinan General Hospital between September 2009 and July 2017. We clarified the diagnosis, collected comprehensive information and categorized patients into three groups: paraneoplastic neurological disorders (PNDs, autoimmune encephalitis (AE, and possible OAAD. Within the three groups, we analyzed a range of clinical and laboratory parameters and used univariate and multivariate regression analysis to identify predictors for poor outcome [modified Rankin Scale (mRS = 3–6].ResultsFrom 158 patients, we identified 70 who fulfilled the criteria for OAAD, including 44 men (62.9% and 26 women (37.1%. There were 38 patients (54.3% in the PNDs group, 14 patients (20% in the AE group, and 18 patients (25.7% in the possible OAAD group. After the last follow-up, 14 (36.8%, 9 (64.2%, and 12 (66.7% had a good outcome (mRS = 0–2. However, 6 (15.8%, 2 (14.3%, and 3 (16.7% died, respectively. Univariate analysis showed that duration prior to the hospital (p = 0.0224 and urinary incontinence/retention (p = 0.0043 were associated with poor outcome (mRS = 3–6. After multivariate regression analysis, urinary incontinence/retention (p = 0.0388 and an immunocompromised state (p = 0.0247 remained as significant factors for poor outcome.ConclusionUrinary incontinence/retention and an immunocompromised state represent significant predictors of a worse prognosis for patients with OAAD. By contrast, cerebrospinal fluid analysis showed that serum autoantibodies and tumor markers, the function of crucial organs, electrophysiology, and radiological findings were not associated with a poor outcome.

    The value of adding induction chemotherapy to chemoradiotherapy in locoregionally advanced nasopharyngeal carcinoma (LA-NPC) remains controversial, yet high-risk patients with LA-NPC have poor outcomes after chemoradiotherapy. We aimed to assess the survival benefits of induction chemotherapy in stage IVa-b NPC. A total of 602 patients with stage IVa-b NPC treated with intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy with or without induction chemotherapy were retrospectively analyzed. Overall survival (OS), locoregional relapse-free survival (LRFS), distant metastasis-free survival (DMFS) and progression-free survival (PFS) were evaluated using the Kaplan-Meier method, log-rank test and Cox regression analysis. In univariate analysis, 5-year OS was 83.2% for induction chemotherapy plus concurrent chemotherapy and 74.8% for concurrent chemotherapy alone, corresponding to an absolute risk reduction of 8.4% (P = 0.022). Compared to concurrent chemotherapy alone, addition of induction chemotherapy improved 5-year DMFS (83.2% vs. 74.4%, P = 0.018) but not 5-year LRFS (83.7% vs. 83.0%, P = 0.848) or PFS (71.9% vs. 66.0%, P = 0.12). Age, T category, N category, chemotherapy strategy and clinical stage were associated with 5-year OS (P = 0.017, P = 0.031, P = 0.007, P = 0.022, P = 0.001, respectively). In multivariate analysis, induction chemotherapy plus concurrent chemotherapy was an independent favorable prognostic factor for OS (HR, 0.62; 95% CI, 0.43-0.90, P = 0.012) and DMFS (HR, 0.57; 95% CI, 0.38-0.83, P = 0.004). In subgroup analysis, induction chemotherapy significantly improved 5-year DMFS in stage IVa (86.8% vs. 77.3%, P = 0.008), but provided no significant benefit in stage IVb. In patients with stage IVa-b NPC treated with IMRT, addition of induction chemotherapy to concurrent chemotherapy significantly improved 5-year OS and 5-year DMFS. This study provides a basis for selection of high risk patients in future clinical therapeutic

    Extra physiotherapy has been associated with better outcomes in hospitalized patients, but this remains an under-researched area in geriatric medicine wards. We retrospectively studied the association between average physiotherapy frequency and outcomes in hospitalized geriatric patients. High frequency physiotherapy (HFP) was defined as ≥0.5 contacts/day. Of 358 eligible patients, 131 (36.6%) received low, and 227 (63.4%) HFP. Functional improvement (discharge versus admission) in the modified Rankin scale was greater in the HFP group (1.1 versus 0.7 points, Pphysiotherapy frequency and intensity in geriatric wards.

    Full Text Available The ‘aging well’ discourse advances the idea of making older people responsible for their capability to stay healthy and active. In the context of an increased ageing population, which poses several challenges to countries’ government, this discourse has become dominant in Europe. We explore the way older people are visually represented on websites of organizations for older people in seven European countries (Finland, UK, the Netherlands, Spain, Italy, Poland and Romania, using an analytical approached based on visual content analysis, inspired by the dimensional model of national cultural differences from the Hofstede model (1991; 2001; 2011. We used two out of the five Hofstede dimensions: Individualism/Collectivism (IDV and Masculinity/Femininity (MAS. The results demonstrated that in all seven countries older people are mostly visually represented as healthy/active, which reflects a dominant ‘ageing well’ discourse in Europe. The results also demonstrated that in most cases older people tend to be represented together with others, which is not consonant with the dominant ‘ageing well’ discourse in Europe. A last finding was that the visual representation of older people is in about half of the cases in line with these Hofstede dimensions. We discuss the implications of these findings claiming that the ‘ageing well’ discourse might lead to ‘visual ageism’. Organizations could keep this in mind while using pictures for their website or in other media and consider to use various kind of pictures, or to avoid using pictures of older people that stigmatize, marginalize or injure. They could look into the cultural situatedness and intersectional character of age relations and consider alternative strategies of both visibility and invisibility to talk with and about our ageing societies.

    Background and propose: Age is an important prognostic marker of patient outcome after breast conserving therapy; however, it is not clear how age affects the outcome. This study aimed to explore the relationship between age with the cell quantity and the radiosensitivity of microscopic disease (MSD) in relation to treatment outcome. Materials and methods: We employed a treatment simulation framework which contains mathematic models for describing the load and spread of MSD based on a retrospective cohort of breast pathology specimens, a surgery simulation model for estimating the remaining MSD quantity and a tumor control probability model for predicting the risk of local recurrence following radiotherapy. Results: The average MSD cell quantities around the primary tumor in younger (age ⩽ 50 years) and older patients were estimated at 1.9 ∗ 10 8 cells and 8.4 ∗ 10 7 cells, respectively (P < 0.01). Following surgical simulation, these numbers decreased to 2.0 ∗ 10 7 cells and 1.3 ∗ 10 7 cells (P < 0.01). Younger patients had smaller average surgical resection volume (118.9 cm 3 ) than older patients (162.9 cm 3 , P < 0.01) but larger estimated radiosensitivity of MSD cells (0.111 Gy −1 versus 0.071 Gy −1 , P < 0.01). Conclusion: The higher local recurrence rate in younger patients could be explained by larger clonogenic microscopic disease cell quantity, even though the microscopic disease cells were found to be more radiosensitive

    Purpose: To evaluate the results of salvage radiotherapy (RT) after inadequate surgery in patients with invasive carcinoma of the cervix. Methods and Materials: Between 1996 and 2001, 105 invasive cervical carcinoma patients were treated at our center with external beam RT with or without intracavitary RT after having undergone total/subtotal hysterectomy at outside institutions. Results: The median follow-up was 34 months. The gap between surgery and RT was 23-198 days (median, 80). Clinically visible residual disease was present in 81 patients (77.1%). Total hysterectomy had been done in 82 patients (78%) and subtotal hysterectomy in 23 patients (22%). The 5-year overall survival, disease-free survival, and pelvic control rates of all patients were 55.2%, 53.3%, and 72.4%, respectively. On univariate analysis, older age, total hysterectomy, hemoglobin level >10 g% before RT, nonsquamous histologic type, use of intracavitary RT, a shorter gap between surgery and RT, and the absence of, or a small volume of, residual disease favorably affected the outcome. The 5-year actuarial rate of late toxicity (Radiation Therapy Oncology Group Criteria) was 19% in the rectum, 4.8% in the bladder, 24.8% in the skin, and 14.3% in the small intestine. Conclusions: Inadequate and inappropriate surgery in invasive cervical cancer with resulting gross residual disease is common in India. Factors such as the use of intracavitary RT, the correction of anemia, and a shorter gap between surgery and RT will enable postoperative RT to achieve acceptable results with minimal morbidity

    Full Text Available To evaluate a holistic multidisciplinary outpatient model of care on hospital readmission, length of stay and mortality in older patients with multimorbidity following discharge from hospital.A pilot case-control study between March 2006 and June 2009 of patients referred on discharge to a multidisciplinary, integrated outpatient model of care that includes outpatient follow-up, timely GP communication and dial-in service compared with usual care following discharge, within a metropolitan, tertiary referral, public teaching hospital. Controls were matched in a 4:1 ratio with cases for age, gender, index admission diagnosis and length of stay.Non-elective readmission rates, total readmission length of stay and overall survival.A total of 252 cases and 1008 control patients were included in the study. Despite the patients referred to the multidisciplinary model of care had slightly more comorbid conditions, significantly higher total length of hospital stay in the previous 12 months and increased prevalence of diabetes and heart failure by comparison to those who received usual care, they had significantly improved survival (adjusted hazard ratio 0.70 95% CI 0.51-0.96, p = 0.029 and no excess in the number of hospitalisations observed.Following discharge from hospital, holistic multidisciplinary outpatient management is associated with improved survival in older patients with multimorbidity. The findings of this study warrant further examination in randomised and cost-effectiveness trials.

    In 2010, China was responsible for nearly 20 percent of global energy use and 25 percent of energy-related carbon dioxide (CO2) emissions. Unlike most countries, China’s energy consumption pattern is unique because the industrial sector dominates the country’s total energy consumption, accounting for about 70 percent of energy use and 72 percent of CO2 emissions in 2010. For this reason, the development path of China’s industrial sector will greatly affect future energy demand and dynamics of not only China, but the entire world. A number of analyses of historical trends have been conducted, but careful projections of the key factors affecting China’s industry sector energy use over the next decade are scarce. This study analyzes industrial energy use and the economic structure of the Chinese manufacturing sector in detail. First, the study analyzes the energy use of and output from 18 industry sub-sectors. Then, retrospective (1995-2010) and prospective (2010-2020) decomposition analyses are conducted for these industrial sectors in order to show how different factors (production growth, structural change, and energy intensity change) influenced industrial energy use trends in China over the last 15 years and how they will do so over the next 10 years. The results of this study will allow policy makers to quantitatively compare the level of structural change in the past and in the years to come and adjust their policies if needed to move towards the target of less energy-intensive industries. The scenario analysis shows the structural change achieved through different paths and helps to understand the consequences of supporting or limiting the growth of certain manufacturing subsectors from the point of view of energy use and structural change. The results point out the industries that have the largest influence in such structural change

    Retrospective, descriptive analysis. To describe the prevalence and nature of insurance claims for injuries attributed to physiotherapy care. In New Zealand, a national insurance scheme, the Accident Compensation Corporation, provides comprehensive, no-fault personal injury coverage. The patterns of injury sustained during physiotherapy care have not previously been described. De-identified data for all injuries registered with the Accident Compensation Corporation from 2005 to 2010 and attributed to physiotherapy were accessed. Prevalence patterns (percentages) of new-claim data were determined for physiotherapy intervention category, injury site, nature of injury, age, and sex. A subcategory, exercise-related injuries, was analyzed according to injury site and whether the injury was related (primary) or unrelated (secondary) to the intended therapeutic goal. There were 279 claims related to physiotherapy care filed with the Accident Compensation Corporation during the studied reporting period. Injury was attributed predominantly to exercise (n = 88, 31.5% of cases) and manual therapy (n = 74, 26.5% of cases). The prevalence of events categorized as exercise related was greatest in those who were 55 to 59 years of age (n = 14, 16.3%) and greater in females (n = 47, 54.7%). Of the exercise-related injuries, 39.8% were in the lower-limb region and 35.2% were categorized as sprains/strains. Injuries attributed to exercise exceeded those linked to other therapies provided by physiotherapists, yet exercise therapy rarely features as a cause of adverse events reported to the physiotherapy profession. The proportion of exercise-related injury events underlines the need for ensuring safe and careful consideration of exercise prescription. Harm, level 4.

    Pain and anxiety control is critical in dental practice. Moderate sedation is a useful adjunct in managing a variety of conditions that make it difficult or impossible for some people to undergo certain dental procedures. The purpose of this study was to analyze the sedation protocols used in 3 dental specialty programs at the Case Western Reserve University School of Dental Medicine, Cleveland, OH. A retrospective analysis was performed using dental school records of patients receiving moderate sedation in the graduate endodontic, periodontic, and oral surgery programs from January 1, 2010, to December 31, 2012. Information was gathered and the data compiled regarding the reasons for sedation, age, sex, pertinent medical conditions, American Society of Anesthesiologists physical status classifications, routes of administration, drugs, dosages, failures, complications, and other information that was recorded. The reasons for the use of moderate sedation were anxiety (54%), local anesthesia failures (15%), fear of needles (15%), severe gag reflex (8%), and claustrophobia with the rubber dam (8%). The most common medical conditions were hypertension (17%), asthma (15%), and bipolar disorder (8%). Most patients were classified as American Society of Anesthesiologists class II. More women (63.1%) were treated than men (36.9%). The mean age was 45 years. Monitoring and drugs varied among the programs. The most common tooth treated in the endodontic program was the mandibular molar. There are differences in the moderate sedation protocols used in the endodontic, periodontic, and oral surgery programs regarding monitoring, drugs used, and record keeping.

  7. Seasonal variation in hemodialysis initiation: A single-center retrospective analysis.

    Directory of Open Access Journals (Sweden)

    Yujiro Maeoka

    Full Text Available The number of new dialysis patients has been increasing worldwide, particularly among elderly individuals. However, information on seasonal variation in hemodialysis initiation in recent decades is lacking, and the seasonal distribution of patients' conditions immediately prior to starting dialysis remains unclear. Having this information could help in developing a modifiable approach to improving pre-dialysis care. We retrospectively investigated the records of 297 patients who initiated hemodialysis at Hiroshima Prefectural Hospital from January 1st, 2009 to December 31st, 2013. Seasonal differences were assessed by χ2 or Kruskal-Wallis tests. Multiple comparison analysis was performed with the Steel test. The overall number of patients starting dialysis was greatest in winter (n = 85, 28.6%, followed by spring (n = 74, 24.9%, summer (n = 70, 23.6%, and autumn (n = 68, 22.9%, though the differences were not significant. However, there was a significant winter peak in dialysis initiation among patients aged ≥65 years, but not in those aged <65 years. Fluid overload assessed by clinicians was the most common uremic symptom among all patients, but a winter peak was only detected in patients aged ≥65 years. The body weight gain ratio showed a similar trend to fluid overload assessed by clinicians. Pulmonary edema was most pronounced in winter among patients aged ≥65 years compared with other seasons. The incidences of infection were modestly increased in summer and winter, but not statistically significant. Cardiac complications were similar in all seasons. This study demonstrated the existence of seasonal variation in dialysis initiation, with a winter peak among patients aged ≥65 years. The winter increment in dialysis initiation was mainly attributable to increased fluid overload. These findings suggest that elderly individuals should be monitored particularly closely during the winter.

    Prospective monitoring of posttraumatic amnesia (PTA) is recommended following moderate to severe traumatic brain injury (TBI). However, few studies have examined the typical order in which items recover on PTA scales. Different methods have been used to define recovery, and the order reported is not consistent across the literature. The purpose of this study was to improve understanding of the progression of PTA by reporting the duration to recovery of items and categories on the Westmead Post-Traumatic Amnesia Scale (WPTAS) according to different criteria. A retrospective analysis was conducted of 66 patients with TBI who were administered the WPTAS during hospital admission. The duration to recovery of items and categories was determined according to 3 criteria: first correct, correct 3 times in a row, and consistently correct. On the basis of the sample mean, date of birth (DOB), year, age, place, month, day, name, and memory for the 3 pictures recovered in this order according to all 3 criteria. However, the significance of differences between items and the order of recovery of categories depended on the criterion adopted. Although DOB recovered first in 74% of cases and the 3 pictures last in 63% of cases, there was a high degree of individual variability in the precise sequence of recovery. The traditional view of PTA recovering in the order of person, place, time, and memory does not adequately describe the profile of recovery on the WPTAS. Considering the recovery of individual items is necessary to understand and account for individuals differences in the order of recovery. (c) 2015 APA, all rights reserved).

    Central airway obstruction (CAO) is a life-threatening situation. Stent insertion re-establishes patency of the central airways. Self-expanding metallic Y stents have been available since 2005, widening the spectrum of interventional bronchoscopic techniques. Retrospective analysis of all patients treated for CAO with a self-expanding metallic Y stent at the Thoraxklinik Heidelberg between May 2005 and January 2009. A total of 43 patients aged 26-81 had a metallic Y stent inserted endoscopically for the treatment of CAO; 39 of these patients (90.7%) had CAO due to malignant disease, four patients (9.3%) due to benign disease. In all 43 patients, the Y stent was deployed without any complications. A longitudinal follow up was possible in 32 of the 43 patients. The stents remained in situ for an average of 107.1 days (range 1-640 days). In 29 patients with malignant CAO the stenosis was successfully overcome with a Y stent; 11 of these patients died within 6 weeks following stent insertion. On follow up the remaining 18 patients showed immediate improvement of dyspnoea. Eight out of the 18 patients (44.4%) tolerated the stent without problems, two (11.1%) required further stenting, six (33.3%) had complications such as increased secretions, cough, dyspnoea or granulation tissue formation. The stent was removed in one patient (5.6%) due to increased secretions, and in another (5.6%) as the stent was no longer required due to successful tumour-specific therapy. Placement of Y stents in symptomatic CAO allows for quick relief of symptoms. Severe complications are rare. Stent removal is possible after successful treatment of the primary tumour. However, the prognostic indicator for survival is the underlying malignancy.

    The purpose of this study was to retrospectively investigate the efficacy of multidisciplinary therapy (concomitant radiotherapy and intra-arterial infusion of 5-fluorouracil (5-FU) followed by maxillectomy) in the treatment of squamous cell carcinoma of the maxillary sinus. We reviewed 71 patient records with locally advanced but respectable carcinoma of the maxillary sinus treated by means of multidisciplinary therapy between 1978 through 1997. The clinical T factor for these patients, according to the UICC definitions (1997), was 12 for T2, 46 for T3, and 13 for T4. Twelve patients were diagnosed as node-positive at initial presentation. Intra-arterial 5-FU was delivered via a superficial temporal artery in accordance with radiotherapy, and the cumulative 5-FU dose ranged from 2,900 mg to 5,250 mg (median 5,000 mg). The total radiotherapy dose ranged from 29 Gy to 48 Gy (median 48 Gy) with conventional fractionation. Patients underwent radical maxillectomy thereafter. The 5-year overall survival rate and disease-specific survival rate of all the patients were 58% and 68%, respectively. There was no significant correlation of clinical T factor or N factor with disease-specific survival on univariate and multivariate analysis. The overall treatment-related mortality rate was 3.7%. Radiation cataract later developed in all evaluable patients whose lenses were within the treatment volume. About a half of the operable T4 patients survived over 5 years by means of the above-mentioned multidisciplinary therapy. This multidisciplinary therapy should be compared to treatment with a combination of surgery and postoperative chemoradiotherapy. (author)

    Bile leakage, while rare, can be a complication seen after cholecystectomy. It may also occur after hepatic or biliary surgical procedures. Etiology may be underlying pathology or surgical complication. Endoscopic retrograde cholangiopancreatography (ERCP) can play major role in diagnosis and treatment of bile leakage. Present study was a retrospective analysis of outcomes of ERCP procedure in patients with bile leakage. Patients who underwent ERCP for bile leakage after surgery between 2008 and 2012 were included in the study. Etiology, clinical and radiological characteristics, and endoscopic treatment outcomes were recorded and analyzed. Total of 31 patients (10 male, 21 female) were included in the study. ERCP was performed for bile leakage after cholecystectomy in 20 patients, after hydatid cyst operation in 10 patients, and after hepatic resection in 1 patient. Clinical signs and symptoms of bile leakage included abdominal pain, bile drainage from percutaneous drain, peritonitis, jaundice, and bilioma. Twelve (60%) patients were treated with endoscopic sphincterotomy (ES) and nasobiliary drainage (NBD) catheter, 7 patients (35%) were treated with ES and biliary stent (BS), and 1 patient (5%) was treated with ES alone. Treatment efficiency was 100% in bile leakage cases after cholecystectomy. Ten (32%) cases of hydatid cyst surgery had subsequent cystobiliary fistula. Of these patients, 7 were treated with ES and NBD, 2 were treated with ES and BS, and 1 patient (8%) with ES alone. Treatment was successful in 90% of these cases. ERCP is an effective method to diagnose and treat bile leakage. Endoscopic treatment of postoperative bile leakage should be individualized based on etiological and other factors, such as accompanying fistula.

    A four-year retrospective analysis of injury data was conducted on a collegiate (NCAA Division I) women’s volleyball team. Twenty athletes (Year 1: age = 19.4 ± 0.9 y, height = 175.2 ± 5.1 cm, body mass = 70.5 ± 10.2 kg; Year 2: age = 20.1 ± 1.0 y, height = 175.7 ± 4.7 cm, body mass = 69.5 ± 10.1 kg; Year 3: age = 20.1 ± 1.4 y, height = 173.8 ± 6.3 cm, body mass = 69.9 ± 10.8 kg; Year 4: age = 19.5 ± 1.4 y, height = 174.4 ± 8.6 cm, body mass = 72.7 ± 10.8 kg) participated in this study, accounting for 1483 total training exposures. Injury was defined as any damage to a body part, incurred during volleyball or strength and conditioning-related activities, which interfered with training and/or competition. Injury rate was normalized to the number of athletes and exposure and expressed as injuries per 1000 exposures. A total of 133 injuries were recorded. The most common injury was to the knee (left = 7.5%, right = 12.0%). Injuries occurred most often in volleyball practice (75.2%), followed by competition (20.3%), and strength and conditioning-related activities (4.5%). Non-contact injuries (upper body = 26.3%, lower body = 53.4%) were more common than contact injuries (upper-body = 13.5%, lower-body = 6.8%). An examination of injury rates relative to the training year revealed patterns in injury occurrence. Specifically, spikes in injury rate were consistently observed during periods of increased training volume that were preceded by breaks in organized training, such as the early pre-season and off-season training periods.

    To evaluate retrospectively the survival outcome, patterns of failure, and complications in patients treated with postoperative chemoradiotherapy (CRT) in advanced gastric cancer. Between January 2000 and December 2006, 80 patients with advanced gastric cancer who received postoperative concurrent CRT were included. Pathological staging was IB-II in 9%, IIIA in 38%, IIIB in 33%, and IV in 21%. Radiotherapy consisted of 45 Gy of radiation. Concurrent chemotherapy consisted of a continuous intravenous infusion of 5-fluorouracil and leucovorin on the first 4 days and last 3 days of radiotherapy. The median follow-up period was 48 months (range, 3 to 83 months). The 5-year overall survival, disease-free survival, and locoregional recurrence-free survivals were 62%, 59%, and 80%, respectively. In the multivariate analysis, significant factors for disease-free survival were T stage (hazard ratio [HR], 0.278; p = 0.038), lymph node dissection extent (HR, 0.201; p = 0.002), and maintenance oral chemotherapy (HR, 2.964; p = 0.004). Locoregional recurrence and distant metastasis occurred in 5 (6%) and 18 (23%) patients, respectively. Mixed failure occurred in 10 (16%) patients. Grade 3 leukopenia and thrombocytopenia were observed in 4 (5%) and one (1%) patient, respectively. Grade 3 nausea and vomiting developed in 8 (10%) patients. Intestinal obstruction developed in one (1%). The survival outcome of the postoperative CRT in advanced gastric cancer was similar to those reported previously. Our postoperative CRT regimen seems to be a safe and effective method, reducing locoregional failure without severe treatment toxicity in advanced gastric cancer patients.

    Critical hand ischemia (CHI) can be devastating and may result in amputation. Distal vessel calcification has been shown to be a major factor in causing CHI. Atherectomy in the upper extremities is not typically considered due to the small anatomy; however, the Diamondback 360° Peripheral Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc.) can access treatment areas with a reference vessel diameter of 1.5mm. A retrospective, observational, single center (Merit Health Center, Jackson, MS) analysis of 11 CHI patients with calcific disease of the radial artery treated with orbital atherectomy (OAS) was completed. Demographics and procedural to 30-day outcomes were assessed. All patients had good blood flow to the hand after intervention and none experienced complications during or immediately post-procedure. At 30-days the freedom from revascularization and amputation was 100%, and all the wounds were healed. The following important principles were followed during the use of OAS for CHI: (1) ACT was therapeutic (~250s); (2) Gentle wire manipulation; (3) Utilization of a small OAS crown (1.25mm); (4) Aggressive vasodilator use-given through the exchange catheter; (5) Angioplasty balloon was matched to the size of the vessel and long and low pressure inflations were completed. Critical hand ischemia can be treated with endovascular techniques. Obtaining good outflow to the fingers is critical for wound healing and preventing amputation. Orbital atherectomy is a useful tool in preparing vessels for balloon angioplasty; particularly in cases where calcification is present. Copyright © 2016 The Authors. Published by Elsevier Inc.

    Full Text Available Abstract Background Patients ingesting ethylene glycol, isopropanol, methanol, and propylene glycol ('toxic alcohols' often present with non-specific signs and symptoms. Definitive diagnosis of toxic alcohols has traditionally been by gas chromatography (GC, a technique not commonly performed on-site in hospital clinical laboratories. The objectives of this retrospective study were: 1 to assess the diagnostic accuracy of the osmolal gap in screening for toxic alcohol ingestion and 2 to determine the common reasons other than toxic alcohol ingestion for elevated osmolal gaps. Methods Electronic medical records from an academic tertiary care medical center were searched to identify all patients in the time period from January 1, 1996 to September 1, 2010 who had serum/plasma ethanol, glucose, sodium, blood urea nitrogen, and osmolality measured simultaneously, and also all patients who had GC analysis for toxic alcohols. Detailed chart review was performed on all patients with osmolal gap of 9 or greater. Results In the study period, 20,669 patients had determination of serum/plasma ethanol and osmolal gap upon presentation to the hospitals. There were 341 patients with an osmolal gap greater than 14 (including correction for estimated contribution of ethanol on initial presentation to the medical center. Seventy-seven patients tested positive by GC for one or more toxic alcohols; all had elevated anion gap or osmolal gap or both. Other than toxic alcohols, the most common causes for an elevated osmolal gap were recent heavy ethanol consumption with suspected alcoholic ketoacidosis, renal failure, shock, and recent administration of mannitol. Only 9 patients with osmolal gap greater than 50 and no patients with osmolal gap greater than 100 were found to be negative for toxic alcohols. Conclusions Our study concurs with other investigations that show that osmolal gap can be a useful diagnostic test in conjunction with clinical history and physical

    The aim of this study was to evaluate the incidence of a variety of infectious complications in patients with CLL regarding the duration of CLL and the type of treatment. We present the retrospective analysis of patients with CLL treated at our institution in years 2004-2016. We collected data about the type of infection, pathogenes, treatment and severity of infections surpassed in connection with administration treatment. In the study one hundred and ten patients were evaluated. The average age of patients was 61.7 years (range 34.5-91.9 years). Fludarabine was the most widely used regimen, followed by bendamustine and alemtuzumab. We recorded 393 episodes of infections, of which 114 (29%) were severe and life threatening of degree 3-5, and 279 (71%) of degree 2. The most common infections were the upper respiratory tract infections together with sinusitis (45.03%), pneumonia (26.20%), CMV reactivation occured in 8.14%, infections of the skin was in 7.6 %. Most infections have occurred with the administration of monoclonal antibody alemtuzumab, these patients were at significantly higher risk of infection [RR 2.59 (1.30 to 5.17)] than patients receiving obinutuzumab [RR 0.63 (0.48 to 0.82)] (p = 0.0001). On the contrary, the safety profile of BCR signaling pathway inhibitors was very acceptable [RR 1.17 (0.70 - 1.96)]. The number of infections have decreased during the first 12 months of treatment with ibrutinib. In the study group we recorded 19 deaths, 8 (7.27%) of them were of infectious etiology. The risk of infectious complications is lifelong in patients with CLL, it can be minimized by early detection and aggressive management. Novel targeted agents used in therapy of CLL have a good safety profile, even the risk of infection is decreased during administration.

    To describe the risk factors and labor characteristics of Clavicular fracture (CF) and brachial plexus injury (BPI); and compare antenatal and labor characteristics and prognosis of obstetrical BPI associated with shoulder dystocia with obstetrical BPI not associated with shoulder dystocia. This retrospective study consisted of women who gave birth to an infant with a fractured clavicle or BPI between January 2009 and June 2013. Antenatal and neonatal data were compared between groups. The control group (1300) was composed of the four singleton vaginal deliveries that immediately followed each birth injury. A multivariable logistic regression model, with backward elimination, was constructed in order to find independent risk factors associated with BPI and CF. A subgroup analysis involved comparison of features of BPI cases with or without associated shoulder dystocia. During the study period, the total number of vaginal deliveries was 44092. The rates of CF, BPI and shoulder dystocia during the study period were 0,6%, 0,16% and 0,29%, respectively. In the logistic regression model, shoulder dystocia, GDM, multiparity, gestational age >42 weeks, protracted labor, short second stage of labor and fetal birth weight greater than 4250 grams increased the risk of CF independently. Shoulder dystocia and protracted labor were independently associated with BPI when controlled for other factors. Among neonates with BPI whose injury was not associated with shoulder dystocia, five (12.2%) sustained permanent injury, whereas one neonate (4.5%) with BPI following shoulder dystocia sustained permanent injury (p = 0.34). BPI not associated with shoulder dystocia might have a higher rate of concomitant CF and permanent sequelae.

    Full Text Available Background and Aims: Cytoreductive surgery (CRS combined with hyperthermic intraperitoneal chemotherapy (HIPEC is becoming the standard treatment option for peritoneal carcinomatosis but is associated with high rates of morbidity and mortality. Our aim was to retrospectively analyse and evaluate intra-operative factors associated with morbidity and mortality of CRS and HIPEC. Methods: Intra-operative data were collected for cases done over 1 year (24 cases and analysed for the primary outcome of post-operative ventilation >24 h, and secondary outcome of length of the Intensive Care Unit (ICU stay >5 days. Statistical analysis was carried out in STATA 11 software. Results: Higher peritoneal carcinoma index (PCI, (P = 0.0047, longer duration of surgery (P = 0.0016, higher delta temperatures (P = 0.0119, increased estimated blood loss (EBL (P = 0.0054, high intraoperative fluid requirement (P = 0.0038, lower mean arterial pressure (MAP (P = 0.0021 and higher blood products requirement were associated with >24 h ventilation. These factors were also associated with longer ICU stay. All these factors associated with >24 h ventilation and prolonged ICU stay are related to the PCI which is an indicator of the extent of surgery. Conclusion: Higher PCI, longer duration of surgery, higher delta temperatures, increased EBL, high intraoperative fluid requirement, lower mean arterial pressure and higher blood products requirement were associated with >24 h postoperative ventilation as well as ICU stay >5 days. All these factors are related to the PCI, which is a major predictor of post-operative morbidity.

    Healthcare-associated pneumonia (HCAP) is associated with drug-resistant pathogens and high mortality, and there is no clear evidence that this is due to inappropriate antibiotic therapy. This study was to elucidate the clinical features, pathogens, therapy, and outcomes of HCAP, and to clarify the risk factors for drug-resistant pathogens and prognosis. Retrospective observational study among hospitalized patients with HCAP over 10 years. The primary outcome was 30-day all-cause hospital mortality after admission. Demographics (age, gender, clinical features, and comorbidities), dates of admission, discharge and/or death, hospitalization costs, microbiological results, chest imaging studies, and CURB-65 were analyzed. Antibiotics, admission to Intensive Care Unit (ICU), mechanical ventilation, and pneumonia prognosis were recorded. Patients were dichotomized based on CURB-65 (low- vs. high-risk). Among 612 patients (mean age of 70.7 years), 88.4% had at least one comorbidity. Commonly detected pathogens were Acinetobacter baumannii, Pseudomonas aeruginosa, and coagulase-negative staphylococci. Initial monotherapy with β-lactam antibiotics was the most common initial therapy (50%). Mean age, length of stay, hospitalization expenses, ICU admission, mechanical ventilation use, malignancies, and detection rate for P. aeruginosa, and Staphylococcus aureus were higher in the high-risk group compared with the low-risk group. CURB-65 ≥3, malignancies, and mechanical ventilation were associated with an increased mortality. Logistic regression analysis showed that cerebrovascular diseases and being bedridden were independent risk factors for HCAP. Initial treatment of HCAP with broad-spectrum antibiotics could be an appropriate approach. CURB-65 ≥3, malignancies, and mechanical ventilation may result in an increased mortality.

    Full Text Available Background: Deep venous thrombosis (DVT of lower limbs is one of the most common cause for the majority of deaths caused by pulmonary embolism. Many medical and surgical disorders are complicated by DVT. Most venous thrombi are clinically silent. B-mode and color Doppler imaging is needed for early diagnosis of DVT to prevent complications and sequalae of DVT. Aim and Objectives: The objectives of the following study were to evaluate the role of Doppler as an imaging modality in diagnosing DVT of lower limbs, to study the spectrum of findings on Doppler ultrasound in patients with DVT. Materials and Methods: Retrospective descriptive analysis of 78 patients of DVT diagnosed on Doppler. Results: Nearly 74% of the patients were males and 26% were females with majority belonging to fifth decade (26%. 75 (96.1% cases showed unilateral while 3 (3.9% cases showed bilateral lower limb involvement. In our study, predominant distribution of thrombus was found to be in above knee region with 69/78 (88.5% patients having thrombus in the superficial femoral vein. Popliteal vein was involved in 54/78 (69.2% patients. Complete thrombosis was observed in 54/78 (69% cases, while partial thrombosis was observed in 24/78 (31% cases. Subacute stage was seen in 42 cases (53.8%, acute stage in 23 cases (29.5% while chronic stage in 13 cases (16.7%. 71 cases (91% had multiple contiguous segmental involvement, whereas 7 cases (9% had isolated vein involvement. Conclusion: Color Doppler is useful in diagnosing DVT in symptomatic and at risk patients and provides a non-invasive method of investigation. It is also helpful in evaluating the site, extent and stage of thrombus.

    Current guidelines favor the radial approach for coronary angiography. Therefore, specialty radial diagnostic catheters were designed to engage both coronary arteries with a single device. However, it is unclear if single catheters are superior to conventional catheters. A retrospective analysis was performed of consecutive right radial coronary angiographies to determine catheter use, fluoroscopy time, radiation dosage, and consumption of contrast. Procedures were performed with a single TIG catheter or conventional catheters (CONV). Procedures with coronary artery bypass grafts or ventricular angiographies were excluded. 273 transradial procedures were performed successfully. 95 procedures were performed with CONV and 178 procedures with a TIG. Crossover to additional catheters was higher in TIG (15.2%) compared to CONV (5.3%, p = 0.02). Fluoroscopy time was comparable between CONV and TIG, without crossover (2.2 ± 1.2 min versus 2.3 ± 1.2 min; n.s.), however, greater in the case of crossover for CONV (5.8 ± 0.7) and TIG (7.6 ± 3.0; p = 0.0001). Radiation dosage was similar in CONV and the TIG, without crossover (1419 ± 1075, cGy∗cm(2) versus 1690 ± 1138; n.s.), however, greater for CONV (2374 ± 620) and TIG (3733 ± 2281, p = 0.05) with crossover. Overall, the amount of contrast was greater in TIG (56 ± 13 mL) versus CONV (48 ± 3 mL; p = 0.0003). CONV femoral catheters may be the primary choice for radial approach.

    Between March 1983 and December 1989, ninety-six patients with intracranial glioma were treated in the Department of Therapeutic Radiology, Kangnam St. Mary Hospital, Catholic University Medical College. We retrospectively reviewed each case to evaluate variable factors influencing the treatment results and to develop an optimal therapy Policy. Median follow-up is 57 months(range:31-133 months). Of the 96 patients, 60(63%) were males and 36(37%) were females. Ages ranged from 3 to 69 years (median 42 years). The most common presenting symptoms were headache(67%) followed by cerebral motor and sensory discrepancy(54%), nausea and vomiting(34%), seizure (19%), mental change(10%) and memory and calculation impairment(8%). Eighty five(88.5%) patients all, except 11(11.5%) brain stem lesions, were biopsy proven intracranial glioma. The distribution by histologic type was 64 astrocytomas(75%), 4 mixed oligoastrocytomas(5%), and 17 oligodendrogliomas(20%). Fourty nine patients (58% were grade I, II histology and 36 (42%) patients were grade III, IV histology. Of the 96 patients, 64(67%) received postoperative RT and 32(33%) were treated with primary radiotherapy. Gross total resection was performed in 14(16%) patients, subtotal resection in 29(34%), partial resection in 21(25%), and biopsy only in 21(25%). Median survival time was 53 months(range 21-133 months), and 2- and, 5-year survival rate were 69%, 49% respectively. 5-year survival rate by histologic grade was grade I, 70%, grade II, 58%, grade III, 28%, and grade IV, 15%. Multivariated analysis demonstrate that age at diagnosis (p=0.121), Karnofsky performance Status(KPS)(p=0.0002), histologic grade(p=0.0001), postoperative radiation therapy(p=0.0278), surgical extent(p=0.024), cerebellar location of tumor(p=0.0095) were significant prognostic factors influencing on survival

    This study aims to understand the demographics, mode of trauma, hospital stay, complications, neurological improvement, mortality and expenditure incurred by Indian patients with spinal trauma and ankylosing spondylitis (AS). Retrospective analysis of the patient data admitted to a tertiary referral hospital from 2008 to 2013 with the diagnosis of AS and spinal trauma was carried out. The variables studied were demographics, mode of trauma, neurological status, neurological improvement, involved vertebral level, duration of hospital stay, comorbid factors, expenditure and complications during the stay. Forty-six patients with diagnosis of AS with spine trauma were admitted over the last 5 years with a total of 52 fractures. All were male patients; 58.6% had injury because of trivial trauma and 78.2% patients presented with neurological injury. C5 C6, C6 C7, C7 D1 and D12 were the most common injured level. Fractures through intervertebral disc were most common in cervical spine. Of the patients, 52.7% had shown neurological improvement of at least grade 1(AIS). Mean expenditure of patient admitted with spinal cord injury (SCI) with AS is 7957 USD (United States dollar), which is around five times the per capita income in India (as per year 2013). Males with AS are much more prone to spinal fractures than females and its incidence may be higher than previously reported. Domestic falls are the most common mechanism of spinal trauma in this population. High velocity injuries are associated with complete SCI. The study reinforces the need for development of subsidized spinal care services for SCI management.

    Although lumbar spondylolysis is encountered in general population with an incidence estimated to be 3-10%, limited information is available for children. The aim of the study is to determine the prevalence of spondylolysis according to associated vertebral bony malformation and spinopelvic parameters in children under eight requiring CT evaluation for unrelated lumbar conditions. Seven hundred and seventeen abdominal and pelvic multi-detector CT scans were obtained in patients under 8 years of age were reviewed. Two board certificated radiologists and two resident radiologists retrospectively evaluated CT scans for lumbar spondylolysis and associated malformations. Pelvic incidence and spondylolisthesis were reported. Our analysis included 717 CT scans in 532 children (259 girls and 273 boys). Twenty-five cases of spondylolysis were diagnosed (16 bilateral and 9 unilateral, 64 and 36%, respectively) in 14 boys (56%) and 11 girls (44%), associating with 12 grade I spondylolisthesis. The mean normal pelvic incidence was 45° (median 44°, SD 7°). The prevalence of spondylolysis was 1% in children under age 3 (n = 3 among 292 patients), 3.7% in children under age 6 (n = 17 among 454 patients) and 4.7% among the 532 patients. Unilateral spondylolysis was significantly associated with a spinal malformation (p = 0.04, Fisher's exact test), with normal pelvic incidence. Half of the patients with bilateral spondylolysis had high pelvic incidence. We observed a prevalence peak of unilateral spondylolysis in the context of a specific malformation in young infants under age 4 with normal pelvic incidence, and, then, a progressive increase in the prevalence of bilateral isolated spondylolysis.

    This retrospective study of medical records, surgical protocols, patient observation cards, and imaging files of 100 patients treated for subdural hematoma analyzed the type of hematoma, patient age and sex, operative technique, neurological status, cause of injury, duration of hospital stay, mortality rate, and the number of and reasons for reoperations to determine the effects on treatment outcomes. The time between the head injury and onset of neurological symptoms was analyzed versus the type of hematoma determined from computed tomography (CT) scans. Acute hematomas accounted for 38% of the cases, with subacute hematomas representing 20%, and chronic ones accounting for 42%. In trauma patients, the mean time interval between the injury and onset of neurological symptoms was 0.38 days for acute hematomas, 13.8 days for subacute hematomas, and 23.75 days for chronic hematomas. Repeat surgery was carried out in 26% of the cases. Improvement was obtained in 44% of cases, deterioration in 20%, and no change in neurological status in 36%. Timing of the operations was between 15:00 and 23:00 in 45%, between 23:00 and 7:00 in 33%, and between 7:00 and 15:00 in 22%. The classification of hematomas based on CT presentation corresponds to the classification based on the time elapsed between injury and onset of symptoms, and appears to be appropriate and useful in everyday practice. No preceding injury was identified in 31.6% of acute hematomas, 50% of subacute hematomas, and 61.9% of chronic hematomas. Analysis of reoperations indicates that trepanation may be superior to craniotomy as primary surgery for subacute and chronic hematomas. Subdural hematoma surgeries take place at all times of the day, with most carried out outside the usual working hours.

    Randomised controlled trials (RCTs) are the gold standard for measuring the efficacy of any medical intervention. The present study assesses the implementation of the CONSORT statement in the top 11 anaesthesiology journals in 2011. We designed this study in order to determine how well authors in the top 11 ranked anaesthesiology journals follow the CONSORT statement's criteria. A retrospective cross-sectional data analysis. The study was performed at the RWTH Aachen University Hospital. Journals included Pain, Anesthesiology, British Journal of Anaesthesia, Regional Anesthesia and Pain Medicine, European Journal of Pain, Anesthesia and Analgesia, Anaesthesia, Minerva Anestesiologica, Canadian Journal of Anesthesia, Journal of Neurosurgical Anesthesiology and the European Journal of Anaesthesiology. All articles in the online table of contents from the top 11 anaesthesiology journals according to the ISI Web of Knowledge were screened for RCTs published in 2011. The RCTs were assessed using the CONSORT checklist. We also analysed the correlation between the number of citations and the adherence to CONSORT items. We evaluated 319 RCTs and found that, more than ten years after the publication of the CONSORT statement, the RCTs satisfied a median of 60.0% of the CONSORT criteria. Only 72.1% of the articles presented clearly defined primary and secondary outcome parameters. The number of citations is only weakly associated with the fulfilment of the CONSORT statement (r = 0.023). Adherence to the CONSORT criteria remains low in top-ranked anaesthesiology journals. We found only a very weak correlation between the number of citations and fulfilment of the requirements of the CONSORT statement.

    Tics are the most frequent abnormal movement in children. A familial history of tics and a personal and familial history of neurobehavioral disturbances are common in children with this abnormality. Tics may seriously compromise daily activities in affected individuals. To identify the characteristics of tics in children and adolescents followed-up in the Neuropediatric Unit of the Hospital Geral de Santo António. We performed a retrospective analysis of patients with tics based on information collected from medical records. The diagnostic criteria of the DSM IV-TR 2000 of the American Psychiatric Association were used. The medical records of 78 children were analyzed, 84.6 % of whom were boys. More than one third of the patients were aged 4 to 8 years old. In 5.1 % of the patients tics developed before the age of 2 years. A familial history of tics, depression and obsessive disorder traits was found in approximately 30 % of patients. The most frequent comorbidity was attention deficit hyperactivity disorder (67.9 %). The occurrence of pediatric autoimmune neuropsychiatric disorders associated with streptococcus infection (PANDAS) was suggested in five patients. In all patients, motor tics occurred before vocal tics. In more than two thirds of the patients, tics were simple. In 59.0 % of the patients, tics were chronic, and in 45.7 % of these met the criteria for Tourette's syndrome. A total of 43.1 % of the patients with chronic tics received pharmacotherapy, risperidone being the most frequently used drug. In general the results of the present study are in agreement with those of previous studies, underlining the need to consider a diagnosis of tics in young children and highlighting the importance of identification and appropriate treatment of comorbidities.

    Full Text Available Objective: To determine if pharmacist-provided medication therapy management (MTM improves medication adherence in Medicare patients. A secondary objective is to compare the total monthly cost of a patient’s prescription medication regimen 6 months before and 6 months following a comprehensive medication review (CMR. Design: Retrospective analysis of medication adherence, pre-post comparison. Setting: Three independent pharmacies in North Carolina. Patients: 97 Medicare Part D beneficiaries with one or more chronic disease states who participated in a comprehensive medication review (CMR. Intervention: MTM services provided by community pharmacists. Main outcome measure: Change in adherence as measured by the proportion of days covered (PDC and change in medication costs for patients and third party payers. Results: Patients were adherent to chronic disease-state medications before and after MTM (PDC≥ 0.8. Overall, change in mean adherence before and after MTM did not change significantly (0.87 and 0.88, respectively; p = 0.43. However, patients taking medications for cholesterol management, GERD, thyroid and BPH demonstrated improved adherence following a CMR. No change in adherence was noted for patients using antihypertensives and antidiabetic agents. Average total chronic disease-state medication costs for participants were reduced from $210.74 to $193.63 (p=0.08 following the comprehensive medication review. Total costs for patient and third party payers decreased from patients prescribed antilipemics, antihypertensives, GERD and thyroid disorders following a CMR. Conclusions: Pharmacist-provided MTM services were effective at improving medication adherence for some patients managed with chronic medications. Pharmacist-provided MTM services also were effective in decreasing total medication costs.

    Implantation of venous access port systems can be performed in local or general anesthesia. In spite of the increasing rate of interventionally implanted systems, the surgical cut-down represents a safe alternative. Thus, the question arises whether--in context to the increasing health-economic pressure--open implantation in general anesthesia is still a feasible alternative to implantation in local anesthesia regarding OR efficiency and costs. In a retrospective analysis, 993 patients receiving a totally implantable venous access device between 2001 and 2007 were evaluated regarding OR utilization, turnover times, intraoperative data and costs. Implantations in local (LA) and general anesthesia (GA) were compared. GA was performed in 762 cases (76.6 %), LA was performed in 231 patients (23.3 %). Mean operation time was similar in both groups (LA 47.27 +/- 1.40 min vs. GA 45.41 +/- 0.75 min, p = 0.244). Patients receiving local anesthesia had a significantly shorter stay in the OR unit (LA 95.9 +/- 1.78 min vs. GA 105.92 +/- 0.92 min; p cut (LA 39.57 +/- 0.69 min vs. GA 50.46 +/- 0.52 min; p material costs were significantly lower in the LA group compared with the GA group (LA: 400.72 +/- 8.25 euro vs. GA: 482.86 +/- 6.23 euro; p systems in local anesthesia is superior in comparison to the implantation under general anesthesia regarding procedural times in the OR unit and costs. With the same operation duration, but less personnel and material expenditure, implantation in local anesthesia offers a potential economic advantage by permitting faster changing times. Implantation in GA only should be performed at a special request by the patient or in difficult venous conditions. Georg Thieme Verlag Stuttgart.New York.

    The British guideline on the management of asthma produced by the British Thoracic Society (BTS) and the Scottish Intercollegiate Guidelines Network (SIGN) describes five steps for the management of chronic asthma. Combination therapy of a long acting β2-agonist (LABA) and an inhaled corticosteroid (ICS) is recommended as first-line therapy at step 3, although the dose of ICS at which to add a LABA is subject to debate. To classify the inhaled therapy prescribed to patients with asthma in NHS Forth Valley according to two interpretations of the BTS/SIGN guideline and to evaluate the use of combination therapy in this population. A retrospective analysis including patients from 46 general practitioner surgeries was conducted. Patients with physician diagnosed asthma were classified according to the BTS/SIGN guideline based on treatment prescribed during 2008. Patient characteristics were evaluated for the overall step classification, and specifically for therapy in step 3. 12,319 patients were included. Guideline interpretation resulted in a shift of 9.2% of patients (receiving medium-dose ICS alone) between steps 2 and 3. The largest proportion of patients (32.3%) was classified at step 4. Age, sex, smoking status, chronic obstructive pulmonary disease co-morbidity, and utilisation of short-acting β2-agonists and oral corticosteroids all correlated with step; however, no differences in these characteristics were evident between low-dose combination therapy and medium-dose ICS alone at step 3. Further studies are needed to evaluate prescribing decisions in asthma. Guideline recommendations regarding the use of ICS dose escalation versus combination therapy need to be clarified relative to the published evidence.

    With continuously increasing expenditure on health care resources, various cost containment strategies have been suggested in regard to controlling the cost of inhalational anaesthetic agents. We performed a cost identification analysis assessing inhalational anaesthetic agent expenditure at a tertiary level hospital, along with an evaluation of strategies to contain the cost of these agents. The number of bottles of isoflurane, sevoflurane and desflurane used during the financial years 1997 to 2007 was retrospectively determined and the acquisition costs and cumulative drug expenditure calculated. Pharmacoeconomic modelling using low fresh gas flow anaesthesia was performed to evaluate practical methods of cost reduction. The use of isoflurane decreased from 384 bottles during 1997 to 204 in 2007. In contrast, use of sevoflurane increased from 226 bottles during 1998 to 875 during 2007. Desflurane use increased from 34 bottles per year during 2002 (its year of introduction) to 163 bottles per year in 2007. While the inflation-adjusted cumulative expenditure for these inhalational agents (Australian dollars) increased from $132,000 in 1997 to over $326,000 in 2007, an increase of 168%, patient workload over the same period increased by only 11%. Pharmacoeconomic modelling demonstrated that sevoflurane at 2 l/minute costs 19 times more than isoflurane at 0.5 l/minute. For the financial years 1997 to 2007, we found a progressive shift from the cheaper isoflurane to the more expensive agents, sevoflurane and desflurane, a shift associated with marked increases in costs. Low flow anaesthesia with isoflurane is one strategy to reduce costs.

    Background: Pregnancy-associated nasopharyngeal carcinoma (PANPC) has been associated with poor survival. Recent advances in radiation technology and imaging techniques, and the introduction of chemotherapy have improved survival in nasopharyngeal carcinoma (NPC); however, it is not clear whether these changes have improved survival in PANPC. Therefore, the purpose of this study was to compare five-year maternal survival in patients with PANPC and non-pregnant patients with NPC. Methods: After adjusting for age, stage and chemotherapy mode, we conducted a retrospective case-control study among 36 non-metastatic PANPC patients and 36 non-pregnant NPC patients (control group) who were treated at our institution between 2000 and 2010. Results: The median age of both groups was 30 years (range, 23–35 years); median follow-up for all patients was 70 months. Locoregionally-advanced disease accounted for 83.3% of all patients with PANPC and 92.9% of patients who developed NPC during pregnancy. In both the PANPC and control groups, 31 patients (86.1%) received chemotherapy and all patients received definitive radiotherapy. The five-year rates for overall survival (70% vs. 78%, p = 0.72), distant metastasis-free survival (79% vs. 76%, p = 0.77), loco-regional relapse-free survival (97% vs. 91%, p = 0.69) and disease-free survival (69% vs. 74%, p = 0.98) were not significantly different between the PANPC and control groups. Multivariate analysis using a Cox proportional hazards model revealed that only N-classification was significantly associated with five-year OS. Conclusion: This study demonstrates that, in the modern treatment era, pregnancy itself may not negatively influence survival outcomes in patients with NPC; however, pregnancy may delay the diagnosis of NPC

    Adult brainstem gliomas are rare primary brain tumors (<2% of gliomas). The goal of this study was to analyze clinical, prognostic and therapeutic factors in a large series of histologically proven brainstem gliomas. Between 1997 and 2007, 104 patients with a histologically proven brainstem glioma were retrospectively analyzed. Data about clinical course of disease, neuropathological findings and therapeutic approaches were analyzed. The median age at diagnosis was 41 years (range 18-89 years), median KPS before any operative procedure was 80 (range 20-100) and median survival for the whole cohort was 18.8 months. Histopathological examinations revealed 16 grade I, 31 grade II, 42 grade III and 14 grade IV gliomas. Grading was not possible in 1 patient. Therapeutic concepts differed according to the histopathology of the disease. Median overall survival for grade II tumors was 26.4 months, for grade III tumors 12.9 months and for grade IV tumors 9.8 months. On multivariate analysis the relative risk to die increased with a KPS ≤ 70 by factor 6.7, with grade III/IV gliomas by the factor 1.8 and for age ≥ 40 by the factor 1.7. External beam radiation reduced the risk to die by factor 0.4. Adult brainstem gliomas present with a wide variety of neurological symptoms and postoperative radiation remains the cornerstone of therapy with no proven benefit of adding chemotherapy. Low KPS, age ≥ 40 and higher tumor grade have a negative impact on overall survival

    The cholinesterase inhibitor rivastigmine is approved for the treatment of mild to moderate Alzheimer's disease. However, it is not possible to predict which individuals will benefit from treatment. This retrospective analysis of an international, 24-week, randomized, double-blind trial aimed to identify the percentage of persons with Alzheimer's disease who have a sustained response with rivastigmine patch, rivastigmine capsules, or placebo; to determine the magnitude of the sustained treatment response; and to investigate baseline patient characteristics predictive of the observed sustained response. Patients who improved on the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) and Alzheimer's Disease Cooperative Study-Activities of Daily Living scale (ADCS-ADL) at week 16 and maintained at least the week 16 improvement at week 24 were identified as sustained responders. Treatment differences and baseline predictive factors were assessed in patients demonstrating a 1-, 2-, 3-, 4-, or 5-point sustained improvement. The first patient was screened in November 2003 and the last patient completed the study in January 2006. More persons with Alzheimer's disease had sustained improvements on the ADAS-cog and ADCS-ADL with rivastigmine versus placebo. Sustained improvements of 4 or 5 points on the ADAS-cog or ADCS-ADL were demonstrated in the 9.5-mg/24-h rivastigmine patch (24% and 36% of patients, respectively) and 12-mg/d capsule groups (28% on both outcome measures). Factors predictive of a sustained response to treatment included baseline Mini-Mental State Examination, ADAS-cog, and ADCS-ADL scores and treatment, country of treatment, and time since first symptom was diagnosed by a physician. Understanding factors predictive of sustained cholinesterase inhibitor treatment response should help to optimize Alzheimer's disease management and encourage compliance by allowing more realistic expectations of treatment effects.

    Autosomal dominant polycystic kidney disease (ADPKD) is the commonest congenital cystic renal disease. Factors such as hypertension, urinary tract infection, hematuria and proteinuria may effect the progression to chronic renal failure in ADPKD patients. Therapeutic interventions, such as the use of angiotensin converting enzyme inhibitors (ACEI) or diet modification, may impact the natural progression of the disease. We aim in this study to review a registry of ADPKD patients in order to compare the slow and fast progressors and identify possible predictors of progression and interventions that slow the progression of this disease. Sheffield Kidney Institute (SKI), one of the largest kidney institutes in Northern Europe, has registered a large number of ADPKD patients since 1981. SKI's computer network contains a wide range of information on these patients. We selected 94 adult polycystic patients from the SKI for retrospective analysis of factors affecting progression to chronic renal failure. Patients who doubled their s. creatinine in 3 6 months were considered fast progressors (FP), while those who doubled their s. creatinine in > 36 months were regarded as slow progressors (SP). There 70 patients in the FP group and 24 patients in the SP group. A third group of 137 patients consisted of non-progressors (NP) who ha d stable s. creatinine levels during the same period. We found that the incidence of hypertension, UTI, macroscopic and microscopic hematuria, and overt proteinuria in the FP group was higher than in SP and NP groups. Modification of some factors, such as hypertension and UTI, may decrease the rate of the deterioration of renal function. (author)

    This report presents a retrospective overview of the greenhouse gas (GHG) emission trends in Europe from 1990 to 2008, with a particular focus on the underpinning drivers and the influence of EU policies. The analysis is based on the combination of decomposition analyses to identify the respective influence of each identified driver and an overview of the main EU policies and their likely effects on these drivers. The period covered by the analysis stops in 2008. As a result, the analysis avoids the effects of the recent economic crisis on GHG emissions. This reinforces the conclusion on long-term emission drivers. The report covers the EU-27 and presents results for the other EEA member countries (Iceland, Liechtenstein, Norway, Switzerland and Turkey) and Croatia (EU candidate country together with Turkey) as far as data is available. The results can be summarized as: 1) Overall GHG emission trends. EU GHG emissions were reduced between 1990 and 2008. Most of the reductions took place in the 1990s, but emissions have also been decreasing every year from 2003 until the last year considered in this report, 2008. 2) Predominant drivers. For the most part, the GHG emission trends observed in the EU between 1990 and 2008 resulted from economic factors. However, EU policies, some of which were not directly targeting GHG emissions, as well as national policies by some front runner countries, also played a role in these trends. 3) Impacts of EU policies. Between 2000 and 2008, emission trends were more directly targeted by a range of energy and climate policies, e.g. the implementation of the European Climate Change programme. However, the steady increase in energy demand during this period - particularly electricity - outweighed the considerable EU-wide savings generated by energy efficiency improvements and the development of renewable energy. 4) Co-benefits. Taking example from the positive benefits on GHG emissions that resulted from the implementation of non

    Full Text Available BACKGROUND: Lactic acidosis is a common cause of high anion gap metabolic acidosis. Sodium bicarbonate may be considered for an arterial pH <7.15 but paradoxically depresses cardiac performance and exacerbates acidosis by enhancing lactate production. This study aimed to evaluate the cause and mortality rate of lactic acidosis and to investigate the effect of factors, including sodium bicarbonate use, on death. METHODS: We conducted a single center analysis from May 2011 through April 2012. We retrospectively analyzed 103 patients with lactic acidosis among 207 patients with metabolic acidosis. We used SOFA and APACHE II as severity scores to estimate illness severity. Multivariate logistic regression analysis and Cox regression analysis models were used to identify factors that affect mortality. RESULTS: Of the 103 patients with a mean age of 66.1±11.4 years, eighty-three patients (80.6% died from sepsis (61.4%, hepatic failure, cardiogenic shock and other causes. The percentage of sodium bicarbonate administration (p = 0.006, catecholamine use, ventilator care and male gender were higher in the non-survival group than the survival group. The non-survival group had significantly higher initial and follow-up lactic acid levels, lower initial albumin, higher SOFA scores and APACHE II scores than the survival group. The mortality rate was significantly higher in patients who received sodium bicarbonate. Sodium bicarbonate administration (p = 0.016 was associated with higher mortality. Independent factors that affected mortality were SOFA score (Exp (B = 1.72, 95% CI = 1.12-2.63, p = 0.013 and sodium bicarbonate administration (Exp (B = 6.27, 95% CI = 1.10-35.78, p = 0.039. CONCLUSIONS: Lactic acidosis, which has a high mortality rate, should be evaluated in patients with metabolic acidosis. In addition, sodium bicarbonate should be prescribed with caution in the case of lactic acidosis because sodium bicarbonate

    To investigate the description of older people and ageing in a major weekly newspaper, influential in political and financial circles, to see whether it reflected ageing in a balanced manner, and to what extent it indulged in apocalyptic demography-the portrayal of population ageing as a financial burden rather than a scientific advance. Electronic search of the digital archive of the Economist of articles published between January 1997 and April 2008. Main outcomes measures Categorisation of articles as portraying population ageing as a burden or a benefit or with a balanced view. Of 6306 identified articles, 262 were relevant. Most featured pensions, demography, and politics. Of these 262, 64% portrayed population ageing as a burden and 12% as a benefit; 24% had a balanced view. Most articles therefore showed a predominantly ageist view of older people as a burden on society, often portraying them as frail non-contributors. Recurrent themes included pension and demographic "time bombs" and future unsustainable costs of health care for older people. This negative view of older people might be influential in shaping the attitudes of readers, who include opinion formers in political and economic circles. Gerontologists (including geriatricians) need to engage with influential media, as well as helping to promote a professional development of journalists that is informed and knowledgeable about the negative impact of ageism on the wellbeing of older people.

    2017-09-01

    Due to the lack of existing literature, the current research explored experiences of same-sex partner bereavement in women over the age of 60. Semi-structured interviews were conducted with eight women. Transcripts were analysed using interpretative phenomenological analysis. Three themes were identified which elaborated the experiences of older women who had lost a same-sex partner: (1) being left alone encapsulated feelings of isolation and exclusion; (2) navigating visibility centred on how homophobia led to a lack of recognition of the women's grief; and (3) finding new places to be authentic related women's need for new relationships in which they could be themselves. The findings indicate that existing models of partner bereavement may provide useful frameworks when seeking to understand the experiences of older women who have lost their same-sex partners. The findings indicate that in addition to the experiences of partner bereavement noted in research with heterosexual widows, older women who lose same-sex partners may face particular challenges, which can impact upon psychological well-being and adjustment to loss. These challenges appear to result from past and current homophobic and heterosexist attitudes within the UK culture. A range of interventions at individual, group, health service, and societal levels may be beneficial in improving the psychological well-being of older women who lose a same-sex partner.

    The study aims to quantify the impact of injury on the financial well-being of older workers. The hypothesis was that injured older workers have substantially reduced income from work following injury, but that New Zealand's (NZ) universal injury compensation scheme mitigates the difference for total income. An e-cohort of 617 722 workers aged 45-64 years old was created using de-identified linked administrative data in NZ's Integrated Data Infrastructure. Person-level data from numerous government agencies were used to compare 21 639 with an injury-related entitlement claim in 2009 with the remaining 596 133. Event date was the date of injury, or for the comparison group, a randomly selected date in 2009. Geometric mean ratios (GMRs) were used to compare income from work and total income from all taxable sources between those injured and the comparison group. Adjusted GMRs estimated income differences up to 36 months following the event date. Differences in total income increased over time. In the third year, those injured received 6.7% less (adjusted GMR 0.933 (95% CI 0.925 to 0.941)) than the comparison group, equivalent to an average loss of $NZ2628. Restricting to income from work, those injured received 29.2% less than the comparison group at 3 years (adjusted GMR 0.708 (95% CI 0.686 to 0.730)). For both men and women, those injured at 45-49 years consistently had the greatest relative income loss compared with those aged 50-54, 55-59 or 60-64 years. Although the substantial impacts of injury on income were mainly mitigated by public income transfers, relative losses in income in those aged 45-64 years increased in the 3 years following injury. Policies focused on adequate compensation and reducing the time away from employment could reduce these financial impacts in older workers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  8. Retrospective and prospective analysis of policy incentives for wind power in Portugal

    been decommissioned despite being in operation for more than 20 years, favoring from new, detailed and hard-to-follow agreements in the legislation. All wind parks that are currently in operation have received feed-in tariffs since they connected to the grid, and are expected to keep receiving them at least until December 2019, and up to December 2036 - depending on year of connection and agreement under the most recent legislation (Diario da Republica 2013). The 2020 renewable energy goals in Portugal include having 6.8 GW of installed wind capacity, which implies the connection of 2 GW in the next years. If no further grid investments are made and wind capacity increases up to 100 MW to the connection point that we analyze, total annual electricity spill is likely to range the 20% to 40%. If the connection grid policy is designed to allow for wind spill, already 'occupied' connection points will be available to new entrants, lowering the total investment costs for new wind parks and increasing their profitability. This thesis is divided in three main parts: a first introductory section, a retrospective study of wind power in Portugal and a prospective analysis of the Portuguese wind power sector. The introductory section is a brief overview of the global renewable status, described in Chapter 1. Chapter 2 and Chapter 3 compile a retrospective study of wind power and the policies that have incentivized wind diffusion. We include in the discussion some references to the future wind power goals, but the results and policy recommendations are directed towards the existing connected wind power capacity.

    Management of mallet finger is both difficult and controversial. Sequelae are not uncommon, particularly after surgical treatment. Many authors advocate orthopedic treatment which is less invasive but requires greater patient participation to implement. Despite the large number of orthopedic methods proposed, none has proven superiority. We report here our experience with a dorsal adhesive splint which preserves digital pulp function and improves observance. This retrospective analysis included 270 mallet fingers presenting 153 tendon injuries and 117 bony injuries in 265 patients aged 42 years on average and treated from 2003 to 2005. Most of the tendon injuries involved the medius (38.7%) and most of the bony injuries involved the ring finger (35.4%). A splint was fashioned for the two distal phalanges and glued to the nail plate filed for this purpose. The splint was fashioned out of an L-shaped plastic sheet of thermo-malleable plastic dipped in hot water (60 degrees C). The L was molded to the dorsal aspect of the phalanges and rolled like a ring around the second phalanx, then glued to the nail. The splint was worn for eight weeks by patients with a tendon injury and six weeks for those with a bony injury. The splint was then worn at night for two weeks. Three criteria were used to analyze outcome: residual extension deficit, joint involvement, complications. Mean follow-up was 18 months. Mean time from trauma to definitive installation of the splint was six days. The complication rate for this orthopedic method was 14.3%, complications being observed in 6% of patients. All complications were transient except for one case of swan neck deformity and one case of painful osteoarthritis. Thirty splints (11%) became unglued but were all reinstalled using the same protocol. Thirty fingers (14%) presented residual deficit of active extension measuring less than 20 degrees. The quality of the result depended on the type of injury: tendon injuries led to extension

    To report a concept analysis of oral hygiene care. Oral hygiene care, as it is provided to older patients in hospital and long-term care settings by nurses and their delegates, has the potential to contribute to the oral health of patients while preventing aspiration pneumonia as well as periodontitis, which itself has been associated with several systemic diseases. However, the state of oral cleanliness in such patients tends to be poor and despite the existence of guidelines, nursing care practices may be inadequate and not reflective of recent advances in knowledge. Concept analysis. A search of electronic databases (2002-2012), use of internet search engines, and hand searching yielded an international data set of 66 research studies, reviews, and practice guidelines. The concept analysis method of Walker and Avant was used to explore the concept of oral hygiene care in the context of frail older patients. Oral hygiene care involves approaches informed by knowing the patient, inspecting the oral cavity, removing plaque, cleansing the oral tissues, decontaminating the oral cavity, using fluoride products and maintaining oral tissue moisture. Those attributes, along with their antecedents and consequences, form a conceptual framework from which a middle-range theory of nurse-administered oral hygiene care is derived that could be tested, evaluated, modified, and translated into practice. Clarity around the concept of oral hygiene care as a nursing intervention could enable nurses to impact oral health outcomes and possibly prevent systemic diseases in older patients. © 2013 Blackwell Publishing Ltd.

    Full Text Available Abstract Background National malaria control programmes must deal with the complex process of changing national malaria treatment guidelines, often without guidance on the process of change. Selecting a replacement drug is only one issue in this process. There is a paucity of literature describing successful malaria treatment policy changes to help guide control programs through this process. Objectives To understand the wider context in which national malaria treatment guidelines were formulated in a specific country (Peru. Methods Using qualitative methods (individual and focus group interviews, stakeholder analysis and a review of documents, a retrospective analysis of the process of change in Peru's anti-malarial treatment policy from the early 1990's to 2003 was completed. Results The decision to change Peru's policies resulted from increasing levels of anti-malarial drug resistance, as well as complaints from providers that the drugs were no longer working. The context of the change occurred in a time in which Peru was changing national governments, which created extreme challenges in moving the change process forward. Peru utilized a number of key strategies successfully to ensure that policy change would occur. This included a having the process directed by a group who shared a common interest in malaria and who had long-established social and professional networks among themselves, b engaging in collaborative teamwork among nationals and between nationals and international collaborators, c respect for and inclusion of district-level staff in all phases of the process, d reliance on high levels of technical and scientific knowledge, e use of standardized protocols to collect data, and f transparency. Conclusion Although not perfectly or fully implemented by 2003, the change in malaria treatment policy in Peru occurred very quickly, as compared to other countries. They identified a problem, collected the data necessary to justify the

    Objective: To evaluate the effectiveness and safety of rectal ultrasound-guided agon-hilium percutaneous cryoablation in treatment of patients with median and or late-stage prostate cancer patients. Methods: Retrospectively analysis of 42 cases of with stage C and D prostate cancer patients treated by rectal ultrasound-guided argon-hilium percutaneous cryoablation during the follow-up of 1-12 months. The prostate specific antigen (PSA), biochemical progression-free survival (bPFS), PSA objective response, transrectal ultrasound of the prostate (TRUS), TRUS-guided biopsy of the prostate, the maximum urinary flow rate(MFR), MRI examination at before, and 3,6,12 months after cryoablation were recorded and evaluated. The results were statistically evaluated by using variance analysis. Results: The PSA value at before and 3,6, 12 months after cryoablation were (4.48±1.35), (3.54±1.67), (3.18±1.76), (2.87±1.89) μg/L, respectively; TRUS-measured prostate volumes at before and 3, 6,12 months after cryoablation were (59.7± 8.2), (46.9±8.3), (26.2±3.9), (25.9±3.7) mm 3 , respectively; MFR before and 3, 6,12 months after cryoablation were (10.4±0.8), (14.3±1.2), (18.3±1.3), (18.9±1.3) ml/s, respectively; Compared with before cryoablation, the differences between before and after cryoablation was statistically significant (F= 53.93,747.92,3843.03, respectively, P<0.01). The bPFS rates in 3 months,6 months and 12 months were 95.2% (40/42), 95.2% (40/42), and 90.5% (38/42), respectively. According to the PSA response, the total effective rate (CR 16 cases, PR 15 cases) at 12 months was 73.8%, and SD was 16.7% (7/42), PD was 9.5% (4/42). Complications included temporary incontinence 2.4% (1/42), Penile tingling/numbness 2.4% (1/42), pelvic pain 4.9% (2/41) and Scrotum Edema 2.4% (1/42). There was no case with severe complications such as severe infection or urethrorectal fistula, etc. Conclusions: Rectal ultrasound-guided agon-hilium percutaneous cryoablation showed

    Occurrence, severity and geographic extent of droughts are anticipated to increase under climate change, but the health consequences of drought conditions are unknown. We estimate risks of cardiovascular and respiratory-related hospitalization and mortality associated with drought conditions for the western U.S. elderly population. For counties in the western U.S. (N=618) and for the period 2000 to 2013, we use data from the U.S. Drought Monitor to identify: 1) full drought periods; 2) non-drought periods; and 3) worsening drought periods stratified by low- and high-severity. We use Medicare claims to calculate daily rates of cardiovascular admissions, respiratory admissions, and deaths among adults 65 years or older. Using a two-stage hierarchical model, we estimated the percentage change in health risks when comparing drought to non-drought period days controlling for daily weather and seasonal trends. On average there were 2·1 million days and 0·6 million days classified as non-drought periods and drought periods, respectively. Compared to non-drought periods, respiratory admissions significantly decreased by -1·99% (95% posterior interval (PI): -3·56, -0·38) during the full drought period, but not during worsening drought conditions. Mortality risk significantly increased by 1·55% (95% PI: 0·17, 2·95) during the high-severity worsening drought period, but not the full drought period. Cardiovascular admissions did not differ significantly during either drought or worsening drought periods. In counties where drought occurred less frequently, we found risks for cardiovascular disease and mortality to increase during worsening drought conditions. Drought conditions increased risk of mortality during high-severity worsening drought, but decreased the risk of respiratory admissions during full drought periods among older adults. Counties that experience fewer drought events show larger risk for mortality and cardiovascular disease. This research describes an

    To evaluate the proxy-rating version of the Prospective and Retrospective Memory Questionnaire (PRMQ) and provide norms and methods for score interpretation. Cross-sectional and correlational. The PRMQ was administered to a large sample drawn from the general adult population (N=570). Confirmatory factor analysis (CFA) was used to test competing models of its latent structure. Various psychometric methods were applied to provide clinicians with tools for score interpretation. The CFA model with optimal fit specified a general memory factor together with additional prospective and retrospective factors. The reliabilities of the PRMQ were acceptable (.83 to .92), and demographic variables did not influence ratings. Tables are presented for conversion of raw scores on the Total scale and Prospective and Retrospective scales to T scores. In addition, tables are provided to allow users to assess the reliability and abnormality of differences between proxy ratings on the Prospective and Retrospective scales. Finally, tables are also provided to compare proxy-ratings with self-ratings (using data from the present sample and self-rating data from a previous study). The proxy-rating version of the PRMQ provides a useful measure of everyday memory for use in clinical research and practice.

    Hospice care can be delivered in different settings, but many patients choose to receive it at home because of familiar surroundings. Despite their preferences, not every home hospice patient manages to die at home. To examine the independent factors associated with home hospice patient dying at home. Retrospective analysis of Hospice Care Association's database. Hospice Care Association is the largest home hospice provider in Singapore. The study included all patients who were admitted into home hospice service from January 1, 2004 to December 31, 2013. Cox proportional hazards modeling with time as constant was used to study the relationship between independent variables and home death. A total of 19,721 patients were included in the study. Females (adjusted risk ratio [ARR] 1.09, 95% CI 1.04-1.15), older patients (ARR 1.01, 95% CI 1.00-1.01), shorter duration of home hospice stay (ARR 0.88, 95% CI 0.82-0.94), fewer episodes of hospitalization (ARR 0.81, 95% CI 0.75-0.86), living with caregivers (ARR 1.54, 95% CI 1.05-2.26), doctor (ARR 1.05, 95% CI 1.01-1.08) and nurse (ARR 1.06, 95% CI 1.04-1.08) visits were positive predictors of dying-at-home. Diagnosis of cancer (ARR 0.93, 95% CI 0.86-1.00) was a negative predictor of dying-at-home. Female, older age, living with a caregiver, non-cancer diagnosis, more doctor and nurse visits, shorter duration of home hospice stays, and fewer episodes of acute hospitalizations are predictive of dying-at-home for home hospice patients.

Postpandemic patients were more likely than pandemic patients to have cardiovascular disease (24 [40%] vs. 1 [6%], respectively; p = 0.015, and they had higher scores on APACHE II (17 [13–22] vs. 14 [10–17], p = 0.002 and SAPS II (40 [31–51] vs. 31 [25–35], p = 0.002 upon admission to the ICU. Postpandemic patients had higher maximal SOFA score (9 [5–12] vs. 5 [4–9], respectively; p = 0.03 during their ICU stay. Postpandemic patients had more often septic shock (40 [66.7%] vs. 8 [50.0%], p = 0.042, and longer median hospital stays (15.0 vs. 8.0 days, respectively; p = 0.006. During 2015–2016, only 18% of the ICU- treated patients had received seasonal influenza vaccination. Conclusions Postpandemic ICU-treated A(H1N1 pdm09 influenza patients were older and developed more often septic shock and had longer hospital stays than influenza patients during the 2009 pandemic.

    To evaluate whole-body magnetic resonance imaging (WB-MRI) for the assessment of bone marrow infiltration in patients with confirmed Gaucher disease type 1 under long-term enzyme replacement therapy (ERT). This retrospective data analysis included 38 patients in two subgroups. Group A: 10 females, 9 males, 15-29 years, mean age 22 years and Group B: 11 females, 8 males, 29-77 years, mean age 49 years, all treated with alglucerase or imiglucerase for at least 12.5 years. Whole-body MRI was carried out in all patients using a standard MRI protocol. Two radiologists assessed all MR images retrospectively with the use of three different MRI score systems: The bone marrow burden (BMB) score, the Duesseldorf-Gaucher score (DGS) and the vertebra disc ratio (VDR). As a clinical component, severity score index type 1 (GD-DS3) was determined. In both groups the MR scores showed low to moderate pathologic levels but no statistically significant difference was found between both groups. The median scores in group A/group B were 7.00/9.00 for the BMB score (p=0.07), 4.00/3.00 for the DGS score (p=0.062) and 1.54/1.62 for the VDR score (p=0.267). The GD-DS3 score was statistically significantly different between both groups (1.6/3.9, p=0.000) and osseous Gaucher disease complications were only found in group B. Bone marrow involvement and typical clinical manifestations are reduced to a minimum, when ERT starts immediately after the confirmed diagnosis of Gaucher disease type 1. The applied MR scores are useful markers to control bone marrow infiltration under enzyme replacement therapy in older patients. Pathologic MR scores in young patients may reflect postponed fat conversion of the juvenile bone marrow. This issue has to be examined in further studies.

    Full Text Available Summary: Background: Addressing the causes of low engagement in health care is a prerequisite for reducing health inequalities. People who miss multiple appointments are an under-researched group who might have substantial unmet health needs. Individual-level patterns of missed general practice appointments might thus provide a risk marker for vulnerability and poor health outcomes. We sought to ascertain the contributions of patient and practice factors to the likelihood of missing general practice appointments. Methods: For this national retrospective cohort analysis, we extracted UK National Health Service general practice data that were routinely collected across Scotland between Sept 5, 2013, and Sept 5, 2016. We calculated the per-patient number of missed appointments from individual appointments and investigated the risk of missing a general practice appointment using a negative binomial model offset by number of appointments made. We then analysed the effect of patient-level factors (including age, sex, and socioeconomic status and practice-level factors (including appointment availability and geographical location on the risk of missing appointments. Findings: The full dataset included information from 909 073 patients, of whom 550 083 were included in the analysis after processing. We observed that 104 461 (19·0% patients missed more than two appointments in the 3 year study period. After controlling for the number of appointments made, patterns of non-attendance could be differentiated, with patients who were aged 16–30 years (relative risk ratio [RRR] 1·21, 95% CI 1·19–1·23 or older than 90 years (2·20, 2·09–2·29, and of low socioeconomic status (Scottish Index of Multiple Deprivation decile 1: RRR 2·27, 2·22–2·31 significantly more likely to miss multiple appointments.

    For large portions of the United States, snow plays a vital role in hydrologic prediction. This is particularly true in the mountain west where snowmelt contributes up to 80% of total streamflow runoff. The Office of Water Prediction (OWP) will begin running the National Water Model (NWM) during the second half of 2016, which is a continental-scale implementation of the WRF-Hydro community hydrologic modeling framework. Assessing and benchmarking the performance of the snow component of the NWM is important for future research-to-operations activities and for forecasters to better understand NWM output. For this study, WRF-Hydro was ran using the same domain and physics options as the NWM (1 km LSM, 250m overland routing, and NHDPlus Version 2.1 channel network). The land surface component chosen is Noah-MP land surface model. Forcing from the National Land Data Assimilation System (NLDAS-2) was downscaled from the native 0.125 degree resolution to the 1 km modeling domain to drive the model. The model was ran over a 5-year retrospective period to gauge multi-year performance of the snow states. Output was analyzed against both in-situ observations, such as SNOTEL, and the Snow Data Assimilation System (SNODAS). In addition, gridded snow states and SNODAS grids were aggregated to Omernik-derived ecological regions. This was done in order to break up snow analysis by regions that share similar ecological and physiographic characteristics. Results show WRF-Hydro is able to capture peak timing across most of the mountain west fairly well. In terms of magnitudes, the model struggles across portions of the west with a low bias. This is especially true in the Cascades, which could be traced back to precipitation partitioning issues in the model. Across the central Rockies, the model exhibits a lower dry bias showing improved performance there. Previous literature suggests a dry bias in the precipitation out west may be contributing to model performance. East of the

    Substantial outbreaks of yellow fever in Angola and Brazil in the past 2 years, combined with global shortages in vaccine stockpiles, highlight a pressing need to assess present control strategies. The aims of this study were to estimate global yellow fever vaccination coverage from 1970 through to 2016 at high spatial resolution and to calculate the number of individuals still requiring vaccination to reach population coverage thresholds for outbreak prevention. For this adjusted retrospective analysis, we compiled data from a range of sources (eg, WHO reports and health-service-provider registeries) reporting on yellow fever vaccination activities between May 1, 1939, and Oct 29, 2016. To account for uncertainty in how vaccine campaigns were targeted, we calculated three population coverage values to encompass alternative scenarios. We combined these data with demographic information and tracked vaccination coverage through time to estimate the proportion of the population who had ever received a yellow fever vaccine for each second level administrative division across countries at risk of yellow fever virus transmission from 1970 to 2016. Overall, substantial increases in vaccine coverage have occurred since 1970, but notable gaps still exist in contemporary coverage within yellow fever risk zones. We estimate that between 393·7 million and 472·9 million people still require vaccination in areas at risk of yellow fever virus transmission to achieve the 80% population coverage threshold recommended by WHO; this represents between 43% and 52% of the population within yellow fever risk zones, compared with between 66% and 76% of the population who would have required vaccination in 1970. Our results highlight important gaps in yellow fever vaccination coverage, can contribute to improved quantification of outbreak risk, and help to guide planning of future vaccination efforts and emergency stockpiling.

Although knowledge of ethics grew steadily between 1970 and 2000, this retrospective analysis identified gaps in our current knowledge. Further research is needed to address the unique ethical problems commonly encountered in all 5 roles of the physical therapist; patient perspectives on ethical issues in physical therapy; variety in ethical approaches; factors affecting moral judgment, sensitivity, motivation, and courage; and cultural dimensions of ethical practice in physical therapy.

    Purpose: This retrospective study was designed to evaluate the role of adjuvant radiotherapy for surgically treated endometrial carcinoma. Patients and methods: From 1980 through 1988, 541 patients were treated with either intravaginal cuff irradiation with a high-dose-rate (HDR) Iridium-192 remote afterloading technique (n=294) or with combined HDR-brachytherapy and additional external pelvic irradiation to 54 Gy (n=247) after surgery for endometrical cancer. Afterloading irradiation was administered in 4 fractions 4 to 6 weeks after surgery. A dose of 30 Gy was delivered at a depth of 0,5 cm from the vaginal mucosa. Results: Patients with HDR-brachytherapy alone showed a 5-year survival of 94.3% for Stage I and 73.6% for Stage II (p=0.0007). Patients who received both brachytherapy and additional pelvic irradiation had a 5-year survival of 94.1% for Stage I, 81.1% for Stage II, 70.4% for Stage III and 46.9% for Stage IV (p=0.0001). The main predictors for survival in a multivariate analysis were stage and grading. Patients with combined readiotherapy had a local recurrence rate of 3.2%, whereas patients with brachytherapy alone who were better selected and had more favorable prognostic factors showed a recurrence rate of 2%. Low-risk patients (Stage I, Grade 1, low infiltration) in the HDR-brachytherapy group had 6 relapses, mainly caused by insufficient treatment on the basis of papillary histology. High-risk patients with poorly differential tumors, which infiltrate more than half the myometrial wall might benefit from additional external radiotherapy in terms of reduction of local recurrence and better survival. Five-year actuarial survival rate was 93.6% after combined radiotherapy vs 86.7% after brachytherapy alone. Complications were graded according to the RTOG scoring system. Severe late complications were fistulas of bladder and/or bowel, which occurred in 2.8% in the combined radiotherapy group, and 0.7% in the HDR brachytherapy group. (orig.) [de

    The most common sites of colorectal cancer (CRC) recurrence are the local tissues, liver or lungs. The objective was to identify risk factors associated with the primary CRC tumor and cancer recurrence in these anatomical sites. Retrospective, longitudinal analyses of data on CRC survivors. Multivariable Cox regression analysis was performed to examine the association between possible cofounders with recurrence to various anatomical sites. Data for 10,398CRC survivors (tumor location right colon=3870, left colon=2898, high rectum=2569, low rectum=1061) were analyzed; follow up time was up to five years. Mean age at curative surgery was 71.5 (SD 11.8) years, 20.2% received radio-chemotherapy, stage T3 (64.4%) and N0 (65.1%) were most common. Overall 1632 (15.7%) had cancer recurrence (Isolated liver n=412, 3,8%;  isolated lung n=252, 2,4%; isolated local n=223, 2.1%). Risk factors associated with recurrent CRC were identified, i.e. isolated liver metastases (male: Adjusted Hazard Ratio (AHR) 1,45; colon left: AHR 1,63; N2 disease: AHR 3,35; T2 disease: AHR 2,82), isolated lung metastases (colon left: AHR 1,53; rectum high: AHR 2,48; rectum low: AHR 2,65; N2 disease 3,76), and local recurrence (glands examined<12: AHR 1,51; CRM <3mm: AHR 1,60; rectum high: AHR 2,15; N2 disease: AHR 2,58) (all p values <0001). Our study finds that the site of the primary CRC tumor is associated with location of subsequent metastasis. Left sided colon cancers have increased risk of metastatic spread to the liver, whereas rectal cancers have increased risk of local recurrence and metastatic spread to the lungs. These results, in combination with other risk factors for CRC recurrence, should be taken into consideration when designing risk adapted post-treatment CRC surveillance programs.

    Abstract Objective To assess trends in and risk factors for readmission to hospital across the age continuum. Design Retrospective analysis. Setting and participants 31 729 762 index hospital admissions for all conditions in 2013 from the US Agency for Healthcare Research and Quality Nationwide Readmissions Database. Main outcome measure 30 day, all cause, unplanned hospital readmissions. Odds of readmission were compared by patients’ age in one year epochs with logistic regression, accounting for sex, payer, length of stay, discharge disposition, number of chronic conditions, reason for and severity of admission, and data clustering by hospital. The middle (45 years) of the age range (0-90+ years) was selected as the age reference group. Results The 30 day unplanned readmission rate following all US index admissions was 11.6% (n=3 678 018). Referenced by patients aged 45 years, the adjusted odds ratio for readmission increased between ages 16 and 20 years (from 0.70 (95% confidence interval 0.68 to 0.71) to 1.04 (1.02 to 1.06)), remained elevated between ages 21 and 44 years (range 1.02 (1.00 to 1.03) to 1.12 (1.10 to 1.14)), steadily decreased between ages 46 and 64 years (range 1.02 (1.00 to 1.04) to 0.91 (0.90 to 0.93)), and decreased abruptly at age 65 years (0.78 (0.77 to 0.79)), after which the odds remained relatively constant with advancing age. Across all ages, multiple chronic conditions were associated with the highest adjusted odds of readmission (for example, 3.67 (3.64 to 3.69) for six or more versus no chronic conditions). Among children, young adults, and middle aged adults, mental health was one of the most common reasons for index admissions that had high adjusted readmission rates (≥75th centile). Conclusions The likelihood of readmission was elevated for children transitioning to adulthood, children and younger adults with mental health disorders, and patients of all ages with multiple chronic conditions.

Patients and methods: A retrospective analysis was performed in patients who were diagnosed with PB at Sun Yat-Sen University Cancer Center from March 1995 to March 2015. Genomic DNA was profiled using a capture-based targeted sequencing panel. Results: Sixteen patients with an average age of 40 years were included in this study. Accurate preoperative diagnosis was very challenging as surgically resected tissues with immunohistochemical staining were required for the diagnosis. Surgery was the optimal treatment for localized disease and there was no standard management for metastatic disease. Mutations were detected among 9 out of the 56 genes profiled, including BRCA2, ERBB4, ALK, MET, BRAF, RAF1, PTEN, EGFR, and PIK3CA. Conclusion: Due to the low incidence rate and the reclassification of PB, no standard treatment is available. Although the numbers of cases are few with varying individual experiences, it is important to improve our understanding regarding this rare lung cancer. Targeted DNA sequencing may be of clinical use for molecular testing and the effects of targeted

    Background and purpose: A retrospective study comparing chemotherapy and radiation, esophagectomy alone versus preoperative radiochemotherapy and surgery in localized squamous-cell esophageal carcinoma. Materials and methods: Between 1989 and 1995, 139 patients (40 stage I, 77 stage IIA and 22 stage IIB according to the UICC 78 TNM classification) were treated in two different institutions. They were divided into three groups according to the treatment proposed: E group (treatment by esophagectomy; n=30), RCT+E group (treatment by preoperative radiochemotherapy and esophagectomy; n=46), RCT group (treatment by radiochemotherapy; n=63). Factors like age, tumor localization and stage were similar in all groups. An intention to treat analysis was made. Results: The E group showed no postoperative mortality, while in the RCT+E group, the surgery mortality was 12.8%. The mortality after RCT was 1.7%. After preoperative radiochemotherapy, a pathological complete response was observed in 25% of cases and the curative resection rate was higher (82% after RCT+E versus 60% after E). The 5-year survival difference between the three groups was not relevant (E group, 12.6%; RCT group, 25.8%; RCT+E group, 38.7%). The median survival was 29, 24 and 28.5 months, respectively. The event-free survival was identical for the E group and the RCT group. For patients treated by radiochemotherapy, local and/or distant relapses were significantly reduced by esophagectomy (relapses occurred in 51% of patients in the RCT+E group versus 75% in the RCT group, P=0.017). Palliative care (dilatations, prosthesis, gastrostomy or jejunostomy) to improve dysphagia was necessary for 38% of patients treated by exclusive radiochemotherapy versus 11% of patients treated by surgery (P=0.001). Conclusions: Treatments by esophagectomy or radiochemotherapy were not significantly different. Preoperative radiochemotherapy and surgery lead to a higher survival rate than exclusive radiochemotherapy, however

    To establish the pattern of change in individual scientific production over the career of medical researchers. Retrospective cohort based on prospectively collected data in a hospital information system. Multicentre university hospital in France. Two distinct populations of 1835 researchers (full professors vs non-academic physicians) having produced 44 723 publications between 1995 and 2014. Annual number of publications referenced in Medline/PubMed with a sensitivity analysis based on publications as first/last author and in high impact journals. The individual volume of publications was modelled by age using generalised estimating equations adjusted for birth cohort, biomedical discipline and academic position of researchers. Averaged over the whole career, the annual number of publications was 5.28 (95% CI 4.90 to 5.69) among professors compared to 0.82 (95% CI 0.76 to 0.89) among non-academic physicians (pscientific production between 25 and 35 years (adjusted incidence rate ratio 102.20, 95% CI 60.99 to 171.30), a maturation phase with a slower increase from 35 to 50 years (2.10, 95% CI 1.75 to 2.51) until a stabilisation phase with constant production followed by a potential decline at the end of career (0.90, 95% CI 0.77 to 1.06). The non-academic physicians experienced a slower pace of learning curve at the beginning of their careers (42.38, 95% CI 25.37 to 70.81) followed by a smaller increase in the annual number of publications (1.29, 95% CI 1.11 to 1.51). Compared to full professors, non-academic physicians had a poor capacity to publish, indicating a low productivity when medical doctors have limited time or little interest in undertaking research. This finding highlights the potential for rethinking the missions of medical doctors towards an enlargement of scientific prerogatives in favour of progress in global knowledge.

    Full Text Available OBJECTIVE: Sporadic Creutzfeldt-Jakob disease (sCJD is a fatal and transmissible neurodegenerative disorder. However, no studies have reported Chinese specific characteristics of sCJD. We aimed to identify differences in sCJD between Chinese patients and patients from other countries. METHODS: The data from 57 Chinese sCJD patients were retrospectively analyzed, including demographic data, clinical manifestations, laboratory examinations, electroencephalograms (EEGs, diffusion-weighted imaging (DWI scans, positron emission tomography (PET scans, and pathological results. RESULT: The disease was pathologically confirmed in 11 patients. 39 cases were diagnosed as probable sCJD, and 7 were possible. Of the total cases, 33 were male, and 24 were female. The onset age ranged from 36 to 75 years (mean: 55.5, median: 57. Disease onset before the age of 60 occurred in 57.9% of patients. The disease duration from onset to death ranged 5-22 months (mean: 11.6, median: 11, and 51.9% of patients died 7 to 12 months after disease onset. The majority of patients presented with sub-acute onset with progressive dementia. 3 of the 9 patients who took 14-3-3 protein analysis had positive results (33.3%. The sensitivity of EEG was 79.6% (43/54. For DWI and PET examinations, the sensitivities were 94% (47/50 and 94.1% (16/17, respectively. In seven patients who did not show typical hyper-intensities on the first DWI examination, abnormalities of hypo-metabolism in the cerebral cortex were clearly detected by PET. In 13 out of the 17 patients, PET detected extra abnormal regions in addition to the hyper-intense areas observed in DWI. CONCLUSION: This is the first study to indicate that Chinese sCJD patients have a much earlier onset age and a longer disease duration than other populations, which is most likely related to racial differences. The longer disease duration may also be a probable characteristic of Asian populations. PET had high sensitivity for the

    Aim: The authors report about follow up the patients after intracavitary irradiation for cystic craniopharyngeoma. Material and Methods: For retrospective analysis 15 patients were selected. The volume of the cyst was determined by CT or MRI. For dosimetry Backlund's formula was used. The cumulative dose to the inner surface of the cyst wall was about 250Gy. 90 Yttrium silicate colloid was administered directly during stereotactically (CT guided) surgery or through the Ommaya drainage system. Control scintigraphy was performed 2-3 hours after 90 Y injection with gamma camera to detect possible leakage of the radioisotope. None of our patients showed evidence of this. In addition to this, the patients were checked daily to pay attention to visual function, neurological condition and possible meningeal irritation. Results: Cyst shrinkage was monitored by repeated CT examinations. CT cyst volume measurement analysed all patients before and 1,2,3 and 5 years after the treatment. In our study 45% of cysts decreased in volume during 4 month, shrinkage of the initial cyst volume was 75% after 1 year. The cyst disappeared nearly totally in 5 patients. Only 3 cyst remain unchanged and 90 Y treatment was repeated. No patients developed a visual field defect or evidence of hypothalamic dysfunction after the treatment. The neuro-opthalmological state completely recovered in 2 patients and improved in 5 patients. The prognosis was good only when an intact optic discs in time of the treatment was present. In some cases the radioisotope was implanted at a late stage of the disease without the opthalmological and neurological improvement. One patient died due to pulmonary embolism one week after the procedure. One patient died within a one year of the treatment from complications related to a solid cystic recurrence. One of typical signs for recurrence was worsening of neuro-opthalmological state. Conclusion: From our results this intracavitary 90 Y therapy is minimally invasive

    The potential benefits and dangers of dietary protein restriction in chronic kidney disease (CKD) are still controversial. Thus, the aim of this study is to evaluate the effect of low protein diet (LPD) on the renal function in nondialysis CKD patients. A retrospective study was conducted from 321 nondialysis CKD patient's medical files (65.1 ± 12.7 yrs, 58.2% men). These patients received individualized dietary protein prescription (0.6-0.8 g protein/kg/day). Protein intake was evaluated by food diary and 24 h-food recall. Adherence to the LPD was considered when patients intake from 90 to 110% of the prescribed amount of protein. The patients were divided into 4 groups: (G1) adherent diabetes mellitus (DM) patients (n = 83); (G2) non-adherent DM patients (n = 106); (G3) adherent non-DM patients (n = 75); (G4) non-adherent non-DM patients (n = 57). Renal function was assessed by estimated glomerular filtration rate (eGFR). Both groups of patients (DM and non-DM) that adhered to the LPD showed significant improvement in eGFR (G1: 38.7 ± 13.2 mL/min to 51.1 ± 17.0 mL/min (p patients, no differences in albumin and BMI were observed at the end of follow up. In non-adherent patients, eGFR significantly decreased in DM group (G2: 44.2 ± 18.5 mL/min to 38.2 ± 15.8 mL/min (p = 0.003)). According to multivariate analysis, annual changes in eGFR were not independent associated with age, gender, BMI, lipid profile, bicarbonate or smoking status. In summary, adherence to low protein diet could be able to improve serum creatinine and eGFR, well-known markers of renal function. However, prospective studies are needed to control confounders which affect renal function and CKD progression.

    The collaborative synthesis of existing datasets, such as long-term climate observations and farmers' crop insurance payments, can increase their overall collective value and societal application. The U.S. Department of Agriculture (USDA) Climate Hubs were created to develop and deliver science-based information and technologies to agricultural and natural resource managers to enable climate-informed decision-making. As part of this mission, Hubs work across USDA and other climate service agencies to synthesize existing information. The USDA Risk Management Agency (RMA) is responsible for overseeing the Federal crop insurance program which currently insures over $100 billion in crops annually. RMA hosts data describing the cause for loss (e.g. drought, wind, irrigation failure) and indemnity amount (i.e. total cost of loss) at multiple spatio-temporal scales (i.e. state, county, year, month). The objective of this paper is to link climate information with indemnities, and their associated cause of loss, to assess climate risk on agricultural production and provide regionally-relevant information to stakeholders to promote resilient working landscapes. We performed a retrospective trend analysis at the state-level for the American Southwest (SW). First, we assessed indemnity-only trends by cause of loss and crop type at varying temporal scales. Historical monthly weather data (i.e. precipitation and temperature) and long-term drought indices (e.g. Palmer Drought Severity Index) were then linked with indemnities and grouped by different causes of loss. Climatological ranks were used to integrate historical comparative intensity of acute and long-term climatic events. Heat and drought as causes of loss were most correlated with temperature and drought indicators, respectively. Across all SW states increasing indemnities were correlated with warmer conditions. Multiple statistical trend analyses suggest a framework is necessary to appropriately measure the biophysical

    The aim of this secondary qualitative descriptive analysis was to examine how nurses construct a definition of older peoples' safety risks and provide care while working within organisational contexts that are focused on diminishing patient risks. Numbers of older patients are increasing in acute hospital contexts-contexts that place their focus on patient safety. Nurses need to manage tensions between older peoples' risks, evidence-informed practice decisions, limited resources and organisational emphases on patient falls. To date, their practice dilemmas have not been well examined. A secondary qualitative descriptive analysis was conducted using data that were collected between June 2010 and May 2011 to examine nursing practice with hospitalised older people. All field notes and transcribed data were reviewed to generate themes representing 18 Registered Nurses' perceptions about safe care for hospitalised older people. The first author generated categories that described how nurses construct definitions of safety risks for older people. All authors engaged in an iterative analytic process that resulted in themes capturing nurses' efforts to provide care in limited resource environments while considering older peoples' safety risks. Nurses constructed definitions of patient safety risks in the context of institutional directives. Nurses provided care using available resources as efficiently as possible and accessing co-worker support. They also minimised the importance of older people's functional abilities by setting priorities for medically delegated tasks and immobilising their patients to reduce their risks. Nurses' definitions of patient risk, which were shaped by impoverished institutional resources and nurses' lack of valuing of functional abilities, contributed to suboptimal care for older adults. Nurses' definitions of risk as physical injury reduced their attention to patients' functional abilities, which nurses reported suffered declines as a result

    Measures of reported self-confidence in performing financial analysis by 59 professional male analysts, 31 born between 1946 and 1964 and 28 born between 1965 and 1976, were investigated and reported. Self-confidence in one's ability is important in the securities industry because it affects recommendations and decisions to buy, sell, and hold securities. The respondents analyzed a set of multiyear corporate financial statements and reported their self-confidence in six separate financial areas. Data from the 59 male financial analysts were tallied and analyzed using both univariate and multivariate statistical tests. Rated self-confidence was not significantly different for the younger and the older men. These results are not consistent with a similar prior study of female analysts in which younger women showed significantly higher self-confidence than older women.

    Prescription sleep medications are often utilized to manage sleep problems among older adults even though these drugs are associated with multiple risks. The aim was to determine the prevalence and characteristics of new-onset compared to chronic sleep medication users and to examine factors associated with the conversion from new to chronic use. A secondary objective was to investigate the impact of sleep medications on health outcomes of injurious falls and patterns of healthcare utilization and expenditures. A 25% random sample of adults ≥ 65 years with 3-year continuous AARP ® Medicare Supplement medical and AARP ® MedicareRx drug plan enrollment was utilized to identify new-onset and chronic sleep medication users. Prescription sleep medication drugs were defined using National Drug Codes (NDCs); falls or hip fractures were identified from diagnosis codes. New users had no sleep medication use in 2014, but initiated medication use in 2015; chronic users had at least one sleep medication prescription in 2014 and in 2015; both groups had follow-up through 2016. Characteristics associated with new users, new users who converted to chronic use, and chronic users were determined using multivariate logistic regression. Prevalence of falls, healthcare utilization and expenditures were regression adjusted. Among eligible insureds, 3 and 9% were identified as new-onset and chronic sleep medication users, respectively. New-onset sleep medication prescriptions were often associated with an inpatient hospitalization. The strongest characteristics associated with new users, those who converted to chronic use, and chronic users were sleep disorders, depression and opioid use. About 50% of new users had > 30 days' supply; 25% converted to chronic use with ≥ 90 days' supply. The prevalence of falls for new-onset users increased by 70% compared to a 22% increase among chronic users. New-onset and chronic sleep medication users were characterized by sleep

    Full Text Available Smart Houses are a prominent field of research referring to environments adapted to assist people in their everyday life. Older people and people with disabilities would benefit the most from the use of Smart Houses because they provide the opportunity for them to stay in their home for as long as possible. In this review, the developments achieved in the field of Smart Houses for the last 16 years are described. The concept of Smart Houses, the most used analysis methods, and current challenges in Smart Houses are presented. A brief introduction of the analysis methods is given, and their implementation is also reported.

    Olfactory dysfunction is common among older adults and affects their safety, nutrition, quality of life, and mortality. More importantly, the decreased sense of smell is an early symptom of neurodegenerative diseases such as Parkinson disease (PD) and Alzheimer disease. However, the genetic determinants for the sense of smell have been poorly investigated. We here performed the first genome-wide meta-analysis on the sense of smell among 6252 US older adults of European descent from the Atherosclerosis Risk in Communities (ARIC) study, the Health, Aging, and Body Composition (Health ABC) study, and the Religious Orders Study and the Rush Memory and Aging Project (ROS/MAP). Genome-wide association study analysis was performed first by individual cohorts and then meta-analyzed using fixed-effect models with inverse variance weights. Although no SNPs reached genome-wide statistical significance, we identified 13 loci with suggestive evidence for an association with the sense of smell (Pmeta < 1 × 10). Of these, 2 SNPs at chromosome 17q21.31 (rs199443 in NSF, P = 3.02 × 10; and rs2732614 in KIAA1267-LRRC37A, P = 6.65 × 10) exhibited cis effects on the expression of microtubule-associated protein tau (MAPT, 17q21.31) in 447 frontal-cortex samples obtained postmortem and profiled by RNA-seq (P < 1 × 10). Gene-based and pathway-enrichment analyses further implicated MAPT in regulating the sense of smell in older adults. Similar results were obtained after excluding participants who reported a physician-diagnosed PD or use of PD medications. In conclusion, we provide preliminary evidence that the MAPT locus may play a role in regulating the sense of smell in older adults and therefore offer a potential genetic link between poor sense of smell and major neurodegenerative diseases.

    The aim of this study is to review the effectiveness of third wave mindfulness-based cognitive behavioral therapies (CBTs) for depressive or anxiety symptomatology in older adults across a wide range of physical and psychological conditions. Electronic literature databases were searched for articles, and random-effects meta-analysis was conducted. Ten studies met the inclusion criteria, of which nine reported the efficacy of interventions on depressive symptoms and seven on anxiety symptoms. Effect-size estimates suggested that mindfulness-based CBT is moderately effective on depressive symptoms in older adults (g = 0.55). The results demonstrated a similar level of overall effect size for anxiety symptoms (g = 0.58). However, there was a large heterogeneity, and publication bias was evident in studies reporting outcomes on anxiety symptoms, and thus, this observed efficacy for late-life anxiety may not be robust. The quality of the included studies varied. Only one study used an active psychological control condition. There were a limited number of studies that used an intent-to-treat (last observation carried forward method) analysis and reported appropriate methods for clinical trials (e.g., treatment-integrity reporting). Third wave mindfulness-based CBT may be robust in particular for depressive symptoms in older adults. We recommend that future studies (i) conduct randomized controlled trials with intent-to-treat to compare mindfulness-based CBT with other types of psychotherapy in older people and (ii) improve study quality by using appropriate methods for checking treatment adherence, randomization, and blinding of assessors.

    In Libya, little is known about HIV-related hospitalizations and in-hospital mortality. This was a retrospective analysis of HIV-related hospitalizations at Tripoli Medical Centre in 2013. Of 227 cases analysed, 82.4% were males who were significantly older (40.0 versus 36.5 years), reported injection drug use (58.3% versus 0%) and were hepatitis C virus co-infected (65.8% versus 0%) compared with females. Severe immunosuppression was prevalent (median CD4 count = 42 cell/μL). Candidiasis was the most common diagnosis (26.0%); Pneumocystis pneumonia was the most common respiratory disease (8.8%), while cerebral toxoplasmosis was diagnosed in 8.4% of patients. Current HAART use was independently associated with low risk of in-hospital mortality (OR 0.33), while central nervous system symptoms (OR 4.12), sepsis (OR 6.98) and low total lymphocyte counts (OR 3.60) were associated with increased risk. In this study, late presentation with severe immunosuppression was common, and was associated with significant in-hospital mortality.

    Full Text Available Integrative veterinary medicine, the combination of complementary and alternative therapies with conventional care, is increasingly prevalent in veterinary practice and a focus of clinical instruction in many academic teaching institutions. However, the presenting complaints, therapeutic modalities, and patient population in an integrative medicine service have not been described. A retrospective analysis of 5,195 integrative patient treatment sessions in a veterinary academic teaching hospital demonstrated that patients most commonly received a combination of therapeutic modalities (39% of all treatment sessions. The 274 patients receiving multiple modalities were most frequently treated for neurologic and orthopedic disease (50.7% versus 49.6% of all presenting complaints, resp.. Older neutered or spayed dogs (mean age = 9.0 years and Dachshunds were treated more often than expected based on general population statistics. Acupuncture, laser therapy, electroacupuncture, and hydrotherapy were frequently administered (>50% patients. Neurologic patients were more likely to receive acupuncture, electroacupuncture, and therapeutic exercises but less likely than orthopedic patients to receive laser, hydrotherapy, or therapeutic ultrasound treatments (P<0.05. The results suggest that the application of these specific modalities to orthopedic and neurologic diseases should be subjected to increased evidence-based investigations. A review of current knowledge in core areas is presented.

    Colin O'Keeffe

    Full Text Available The pressures of patient demand on emergency departments (EDs continue to be reported worldwide, with an associated negative impact on ED crowding and waiting times. It has also been reported that a proportion of attendances to EDs in different international systems could be managed in settings such as primary care. This study used routine ED data to define, measure and profile non-urgent ED attendances that were suitable for management in alternative, non-emergency settings.We undertook a retrospective analysis of three years of Hospital Episode and Statistics Accident Emergency (HES A&E data for one large region in England, United Kingdom (April 1st 2011 to March 31st 2014. Data was collected on all adult (>16 years ED attendances from each of the 19 EDs in the region. A validated process based definition of non-urgent attendance was refined for this study and applied to the data. Using summary statistics non-urgent attenders were examined by variables hypothesised to influence them as follows: age at arrival, time of day and day of week and mode of arrival. Odds ratios were calculated to compare non-urgent attenders between groups.There were 3,667,601 first time attendances to EDs, of which 554,564 were defined as non-urgent (15.1%. Non-urgent attendances were significantly more likely to present out of hours than in hours (OR = 1.19, 95% CI: 1.18 to 1.20, P<0.001. The odds of a non-urgent attendance were significantly higher for younger patients (aged 16-44 compared to those aged 45-64 (odds ratio: 1.42, 95% CI: 1.41 to 1.43, P<0.001 and the over 65's (odds ratio: 3.81, 95% CI: 3.78 to 3.85, P<0.001.

    The aim of this study was to analyze the association between the presence of actinic lesions (solar keratosis and non-melanoma skin cancer) and osteoporotic hip fractures in older patients. Both pathologies are common conditions in this age group. Since cumulative sun exposure is difficult to quantify, the presence of actinic lesions can be used to indirectly analyze the association between ultraviolet radiation and osteoporotic hip fractures. This was an observational case-control study. We reviewed the centralized medical records of patients with hip fracture (cases, n = 51) and patients with other diseases hospitalized in the same institution and period (controls, n = 59). The mean age of the patients was 80 ± 8.3 years (range 50-103 years). Differences in maternal hip fracture history were found between cases and controls (14.8 and 8 %, respectively; p = 0.047). Falls history in the past year was higher in cases than in controls (p < 0.0001). Actinic lesions were observed in 32.7 % of patients (prevalence rate 23.5 % in cases, 40.7 % in controls; p = 0.04). When considering patients with actinic lesions, controls have a higher FRAX score compared with cases. Although sun exposure is recommended for bone health, it represents a risk factor for actinic lesions. The presence of actinic lesions may indicate a lower osteoporotic hip fracture risk. A balance between adequate lifetime sun exposure and protection against its adverse effects is required for each patient, in the context of geographic location.

    The current retrospective chart review compared glycemic control and cost impact of two insulin administration systems, V-Go ® versus usual care with standard of care (SOC) insulin injections, in eight patients residing in a nursing home (NH). A total of 1,937 blood glucose (BG) values were collected over 61 days. Significant improvements were observed for the V-Go versus SOC group in time in range 100 mg/dL to 200 mg/dL (V-Go 59.09% vs. SOC 34.02%; p < 0.001), reduced BG fluctuations as measured by standard deviation (V-Go 61.2 vs. SOC 92.1; p < 0.001), and improved mean daily BG (V-Go 159.38 mg/dL vs. SOC 223.86 mg/dL; p < 0.001). The estimated A1c change, calculated from BG values, decreased from 8.9% to 7.2% in the V-Go group and increased from 9.0% to 9.4% in the SOC group. Compared to SOC, use of V-Go decreased the mean time for insulin administration by nursing staff by 26.3 minutes per patient per day and associated labor costs by $328.75 per patient per month. Insulin administration with V-Go may improve glycemic control and reduce administration costs compared to existing care in the NH setting. [Journal of Gerontological Nursing, 43(1), 10-16.].

  18. Roads not taken: A narrative positioning analysis of older adults' stories about missed opportunities.

    Blix, Bodil Hansen; Hamran, Torunn; Normann, Hans Ketil

    2015-12-01

    The point of departure for this article is narrative gerontology's conceptualization of life as storied and the assumption that identity development and meaning making do not cease at any age, but rather continue throughout life. We suggest that if identity construction is considered to be a lifelong project, narrative gerontology would benefit from applying analytical perspectives focused on the situated activity of narration. In this article, we apply a three-level positioning analysis to segments of interviews with two elderly Sami women concerning missed opportunities or roads not taken and, more specifically, to narrations about missed opportunities for education. We argue that such narrations should not necessarily be considered expressions of regret or processes of reconciliation but rather as pivotal in here-and-now identity constructions. Narrations about missed opportunities demonstrate that what narrators choose to insert into their life stories is chosen for a purpose and for an audience in a specific interpersonal and discursive context. We suggest that narrative gerontology would benefit from a broader focus on the diversity of sites of engagement in which older adults perform identity constructions. This shift implies moving beyond traditional studies of older adults' life stories and biographical narratives as related in the context of qualitative research interviews (of which the present study of Sami older adults' life stories is indeed an example).

    Full Text Available Background. Although a number of studies have examined sociodemographic, psychosocial, and environmental determinants of the level of physical activity (PA for older people, little attention has been paid to the predictive power of cognitive strategies for independently living older adults. However, cognitive strategies have recently been considered to be critical in the management of day-to-day living. Methods. Data were collected from 243 men and women aged 55 years and older living in France using face-to-face interviews between 2011 and 2013. Results. A stepwise discriminant analysis selected five predictor variables (age, perceived health status, barriers’ self-efficacy, internal memory, and attentional control strategies of the level of PA. The function showed that the rate of correct prediction was 73% for the level of PA. The calculated discriminant function based on the five predictor variables is useful for detecting individuals at high risk of lapses once engaged in regular PA. Conclusions. This study highlighted the need to consider cognitive functions as a determinant of the level of PA and, more specifically, those cognitive functions related to executive functions (internal memory and attentional control, to facilitate the maintenance of regular PA. These results are discussed in relation to successful aging.

    This study used a person-centred approach to explore typologies of older manual workers based on presenteeism, stress resilience, and physical activity. Older manual workers ( n  = 217; 69.1% male; age range 50-77; M age = 57.11 years; SD = 5.62) from a range of UK-based organisations, representing different manual job roles, took part in the study. A cross-sectional survey design was used. Based on the three input variables: presenteeism, stress resilience and physical activity, four distinct profiles were identified on using Latent Profile Analysis. One group ('High sport/exercise and well-functioning'; 5.50%) engaged in high levels of sport/exercise and exhibited low levels of stress resilience and all types of presenteeism. Another profile ('Physically burdened'; 9.70%) reported high levels of work and leisure-time physical activity, low stress resilience, as well as high levels of presenteeism due to physical and time demands. A 'Moderately active and functioning' group (46.50%) exhibited moderate levels on all variables. Finally, the fourth profile ('Moderately active with high presenteeism'; 38.20%) reported engaging in moderate levels of physical activity and had relatively high levels of stress resilience, yet also high levels of presenteeism. The profiles differed on work affect and health perceptions largely in the expected directions. There were no differences between the profiles in socio-demographics. These results highlight complex within-person interactions between presenteeism, stress resilience, and physical activity in older manual workers. The identification of profiles of older manual workers who are at risk of poor health and functioning may inform targeted interventions to help retain them in the workforce for longer.

    Adults aged 50 and older make up half of individuals experiencing homelessness and have high rates of morbidity and mortality. They may have different life trajectories and reside in different environments than do younger homeless adults. Although the environmental risks associated with homelessness are substantial, the environments in which older homeless individuals live have not been well characterized. We classified living environments and identified associated factors in a sample of older homeless adults. From July 2013 to June 2014, we recruited a community-based sample of 350 homeless men and women aged fifty and older in Oakland, California. We administered structured interviews including assessments of health, history of homelessness, social support, and life course. Participants used a recall procedure to describe where they stayed in the prior six months. We performed cluster analysis to classify residential venues and used multinomial logistic regression to identify individual factors prior to the onset of homelessness as well as the duration of unstable housing associated with living in them. We generated four residential groups describing those who were unsheltered (n = 162), cohabited unstably with friends and family (n = 57), resided in multiple institutional settings (shelters, jails, transitional housing) (n = 88), or lived primarily in rental housing (recently homeless) (n = 43). Compared to those who were unsheltered, having social support when last stably housed was significantly associated with cohabiting and institution use. Cohabiters and renters were significantly more likely to be women and have experienced a shorter duration of homelessness. Cohabiters were significantly more likely than unsheltered participants to have experienced abuse prior to losing stable housing. Pre-homeless social support appears to protect against street homelessness while low levels of social support may increase the risk for becoming homeless immediately after

    There are cross-sectional evidences of an association between sleep disorders and cognitive impairment on older adults. However, there are no consensus by means of longitudinal studies data on the increased risk of developing dementia related to insomnia. We conduct a systematic review and meta-analysis to evaluate the risk of incident all-cause dementia in individuals with insomnia in population-based prospective cohort studies. Five studies of 5.242 retrieved references were included in the meta-analysis. We used the generic inverse variance method with a random effects model to calculate the pooled risk of dementia in older adults with insomnia. We assessed heterogeneity in the meta-analysis by means of the Q-test and I2 index. Study quality was assessed with the Newcastle-Ottawa Scale The results showed that Insomnia was associated with a significant risk of all-cause dementia (RR = 1.53 CI95% (1.07-2.18), z = 2.36, p = 0.02). There was evidence for significant heterogeneity in the analysis (q-value = 2.4, p < 0.001 I2 = 82%). Insomnia is associated with an increased risk for dementia. This results provide evidences that future studies should investigate dementia prevention among elderly individuals through screening and proper management of insomnia. Copyright © 2016 Elsevier Ltd.

    The incidence of foodborne illness is higher in older adults because of their increased susceptibility; therefore, food safety practices are important. However, inadequate knowledge and negative attitudes toward food safety have been reported, which may increase use of unsafe food handling practices. Data on the actual food safety behaviors of older adults are lacking. In this study, food safety practices of older adults were observed and linked to microbiological analysis of kitchen surfaces to identify suspected routes of contamination. Older adults (≥60 years, n = 100) prepared a set meal in a model domestic kitchen sanitized according to a validated protocol to ensure minimal and consistent microbiological loads. Food safety behaviors were observed using ceiling-mounted cameras and recorded using a predetermined behavioral checklist. Surface microbiological contamination also was determined after food preparation. Overall, older adults frequently implemented unsafe food handling practices; 90% failed to implement adequate hand decontamination immediately after handling raw chicken. For older adults who used a larger number of adequate hand decontamination attempts, microbiological contamination levels in the kitchen following the food preparation session were significantly lower ( P food handling practices as suspected routes of microbiological cross-contamination in a model domestic kitchen. Findings indicate the potential impact on domestic food safety of unsafe food handling practices used by older adult consumers. This innovative approach revealed that a large proportion of older adults implement behaviors resulting in microbiological cross-contamination that may increase the risk of foodborne illness in the home.

    This study aims to explore the feasibility of icotinib neoadjuvant therapy for nonsmall cell lung cancer (NSCLC). This was a retrospective analysis of the clinical data for 63 NSCLC patients (61 cases of adenocarcinoma and two cases of squamous cell carcinoma) receiving surgical resection of lung lesions after oral intake of icotinib from December 2011 to November 2013 in the PLA General Hospital. Preoperative oral intake of the patients was icotinib 125 mg tid, drug side effects were evaluated according to the American National Cancer Institute Common Toxicity Criteria Version 4.0; computed tomography scan was done on the day taking medicine and 2 weeks later to determine tumor changes. After oral intake of Icotinib for 2 to 22 weeks (5 cases for 2 weeks,13 cases for 3 to 22 weeks), all patients receive surgical resection of lung cancer lesions, and testing of removed tumor to evaluate the epidermal growth factor receptor (EGFR) gene mutation status was performed by fluorescence polymerase chain reaction. The patients with sensitive EGFR mutations receive Icotinib as postoperative adjuvant therapy. Side effects of medication within 2 weeks included rash (44.4%, 28/63), dry skin (34.9%, 22/63), diarrhea (14.3%, 9/63), and oral ulcer (1.6%, 1/63); there were no icotinib-associated thoracic surgery complications during the perioperational period. 71.4% patients (45/63) achieve an average reduction of 23.5% ±10.7%(10%-53.5%) after 2 weeks medication of Icotinib(regressive tumor[RT]) .28.6% patients(18/63) achieve stable tumor(ST),enlargement of 8.7% to reduction of 8.7% of the maximum diameter of lung cancer after 2 weeks medication of Icotinib. Of the RT group, 68.9% (31/45) of the tumors were detected with EGFR-sensitive mutation (exon 19 or 21 mutation), 24.4% (11/45) with wild-type EGFR, and three cases of exon 20 mutation. Of the ST group, 77.8% (14/18) were detected with wild-type EGFR, three cases of exon 20 mutation, and one case of exon 19 deletion mutation

    People are living longer, but with increased age comes greater frailty and multi-morbidity. This secondary data analysis examines transcripts from interviews with 11 frail older people and 6 informal carers to explore emotion in relation to frailty and deteriorating health. Anger and frustration were frequently experienced with declining functional ability; sadness occurred with social isolation, loss of autonomy and independence; anxiety was evident when transition to a care home was discussed; and contentment was described when connecting with others. Reluctant acceptance emerged as a coping strategy. Insights gained from analysing emotion may inform communications training courses for community nurses, though further research is required.

    Full Text Available There is a lack of research on the everyday lives of older people in developing countries. This exploratory study used structured observation and content analysis to examine the presence of older people in public fora and considered the methods’ potential for understanding older people’s social integration and inclusion. Structured observation occurred of public social spaces in six cities each located in a different developing country and in one city in the United Kingdom, together with content analysis of the presence of people in newspaper pictures and on television in the selected countries. Results indicated that across all fieldwork sites and data sources, there was a low presence of older people, with women considerably less present than men in developing countries. There was variation across fieldwork sites in older people’s presence by place and time of day and in their accompanied status. The presence of older people in images drawn from newspapers was associated with the news/non-news nature of the source. The utility of the study’s methodological approach is considered, as is the degree to which the presence of older people in public fora might relate to social integration and inclusion in different cultural contexts.

    The radiation dose should be accurately measured in order to relate its effect to the cells. The assessment of dose usually performed using biological dosimetry techniques. However, the reduction of lymphocytes (white blood cells) after the time period results in inaccuracy of dose measurement. An alternative method used is the application of Electron Spin Resonance (ESR) using tooth enamel. In this study, tooth enamels were evaluated and used to measure the individual absorbed dose from the background. The basic tooth features that would affect dose measurement were discussed. The results show this technique is capable and effective for retrospective dose measurement and useful for the study of radiation effect to human. (author)

    Objectives: Personality traits are associated with risk of dementia; less is known about their association with the trajectory of cognitive functioning. This research examines the association between the 5 major dimensions of personality and cognitive function and decline in older adulthood and includes a meta-analysis of published studies. Method: Personality traits, objective and subjective memory, and cognitive status were collected in a large national sample (N = 13,987) with a 4-year follow-up period. For each trait, the meta-analysis pooled results from up to 5 prospective studies to examine personality and change in global cognition. Results: Higher Neuroticism was associated with worse performance on all cognitive measures and greater decline in memory, whereas higher Conscientiousness and Openness were associated with better memory performance concurrently and less decline over time. All traits were associated with subjective memory. Higher Conscientiousness and lower Extraversion were associated with better cognitive status and less decline. Although modest, these associations were generally larger than that of hypertension, diabetes, history of psychological treatment, obesity, smoking, and physical inactivity. The meta-analysis supported the association between Neuroticism and Conscientiousness and cognitive decline. Discussion: Personality is associated with cognitive decline in older adults, with effects comparable to established clinical and lifestyle risk factors. PMID:25583598

    Odontomas represent the most common type of odontogenic jaw tumors among patients younger than 20 years of age. Clinically, they are often associated with eruption failure of adjacent permanent teeth, and are classified as compound and complex. The aim of the present retrospective study was to present the characteristics, treatment approach and outcome of odontomas in Greek children, over a ten-year period. Twenty six patients, 2 to 14 years of age (mean 9.3 years), with odontomas treated during the years 1999-2008 at the Department of Oral and Maxillofacial Surgery of a Children's Hospital, were included in the study. Data from patients' files were retrieved and they were recalled for review. Odontomas were equally distributed in the maxilla and mandible and 42.3% of them were located in the anterior maxilla. Of the odontomas, 80.7% were related to disturbances in tooth eruption. Bone expansion was observed in 65.3% of the cases. All odontomas were surgically removed, and related impacted permanent teeth were either left to erupt spontaneously, orthodontically guided into occlusion or were removed. Orthodontic intervention appeared to be necessary in older children, while in younger children spontaneous eruption was frequent. In the present study, odontomas were associated with unerupted or impacted teeth. Radiographic examination was essential to verify the presence of the tumor and early removal prevented tooth eruption failure and disturbances in a majority of the cases. (author)

    Adjuvant chemotherapy after surgery improves survival of patients with stage II-III, resectable gastric cancer. However, the overall survival benefit observed after adjuvant chemotherapy is moderate, suggesting that not all patients with resectable gastric cancer treated with adjuvant chemotherapy benefit from it. We aimed to develop and validate a predictive test for adjuvant chemotherapy response in patients with resectable, stage II-III gastric cancer. In this multi-cohort, retrospective study, we developed through a multi-step strategy a predictive test consisting of two rule-based classifier algorithms with predictive value for adjuvant chemotherapy response and prognosis. Exploratory bioinformatics analyses identified biologically relevant candidate genes in gastric cancer transcriptome datasets. In the discovery analysis, a four-gene, real-time RT-PCR assay was developed and analytically validated in formalin-fixed, paraffin-embedded (FFPE) tumour tissues from an internal cohort of 307 patients with stage II-III gastric cancer treated at the Yonsei Cancer Center with D2 gastrectomy plus adjuvant fluorouracil-based chemotherapy (n=193) or surgery alone (n=114). The same internal cohort was used to evaluate the prognostic and chemotherapy response predictive value of the single patient classifier genes using associations with 5-year overall survival. The results were validated with a subset (n=625) of FFPE tumour samples from an independent cohort of patients treated in the CLASSIC trial (NCT00411229), who received D2 gastrectomy plus capecitabine and oxaliplatin chemotherapy (n=323) or surgery alone (n=302). The primary endpoint was 5-year overall survival. We identified four classifier genes related to relevant gastric cancer features (GZMB, WARS, SFRP4, and CDX1) that formed the single patient classifier assay. In the validation cohort, the prognostic single patient classifier (based on the expression of GZMB, WARS, and SFRP4) identified 79 (13%) of 625

    In a retrospective study of prelinguistic communication development, clinically referred preschool children (n = 9) aged 3-4 years, who as infants had failed a community-based screening program, were evaluated for features of childhood apraxia of speech (CAS). Four children showed no features and either delayed or normal language, five had from three-to-seven CAS features and all exhibited delayed language. These children were matched by age with 21 children with typically-developing (TD) speech and language skills. Case-control comparisons of retrospective data from 9 months of age for two participants with more severe features of CAS at preschool age showed a dissociated pattern with low expressive quotients on the Receptive-Expressive Emergent Language Assessment-Second Edition (REEL-2) and records of infrequent babbling, but normal receptive quotients. However, other profiles were observed. Two children with milder CAS features showed poor receptive and expressive development similar to other clinically referred children with no CAS features, and one child with severe CAS features showed poor receptive but normal expressive developmental milestones at 9 months and records of frequent babbling. Results suggest some but not all children with features of suspected CAS have a selective deficit originating within speech motor development.

    Full Text Available Objectives: To investigate the incidence of parasitic infestations and inflammation accompanying parasitosis in a series of appendectomy cases. Methods: Six-hundred-sixty patients who had undergone appendectomy in Bingöl State Hospital, Bingol, Turkey with the preliminary diagnosis of appendicitis between January 2012 and February 2015 were included in this retrospective study. They were retrospectively evaluated in terms of age, gender and pathological findings. Cases diagnosed with parasitic infestations were re-evaluated histopathologically for inflammatory response. Results: The mean age was 19.6 years, and the male/female ratio was 1.8. When evaluated in terms of histopathological diagnoses, 573 (86.8% were diagnosed as acute appendicitis, and parasitic infestation was identified in 12 (1.8%. Among cases with parasitic infestation, Enterobius vermicularis was identified in 9 (75% and Taenia in 3 (25% cases. Of cases with Enterobius vermicularis, 4 (44.4% had lymphoid hyperplasia, 1 (11.1% had normal-structured appendix vermiformis, and 4 (44.4% had findings of acute appendicitis. All cases with taeniasis had an inflammatory response: acute appendicitis was identified in 2 (66% and acute gangrenous appendicitis in 1 (33% of them. Conclusion: Parasitic infestations are among the probable causes in appendicitis etiology and should be kept in mind during differential diagnosis. However, whether every parasitic infestation leads to appendiceal inflammatory response is controversial.

    Cognitive disorders pose a major problem in the aging population across the globe. Acupoint massage has been used to improve cognitive functions in older adults. In this study, the authors performed a meta-analysis to evaluate the usefulness of acupoint massage in preventing cognitive declines in older adults. The authors searched for randomized controlled trials (RCTs) reporting on the effectiveness of acupoint massage on cognition in older adults in the following literature databases: PubMed, MEDLINE, Embase, CINAHL, ScienceDirect, Foreign Medical Journal Service, Cochrane Library, VIP Information, Chinese National Knowledge Infrastructure, WANFANG, and Chinese Biomedical. Two reviewers independently extracted the data related to the study and participants' characteristics and the cognitive impairment outcomes. Only RCTs meeting the inclusion criteria were used in the present meta-analysis. Eight RCTs with 657 participants in total (age ≥60 years) were included. It is actually 8 for synthetic and 6 in the meta-analysis. The authors calculated the pooled estimates of the random effects of changes in the Mini-Mental State Examination to compare the groups with and without acupoint massage. The merged mean difference (MD) was 1.94 (95% confidence interval, C.I., [1.41-2.47], p < 0.00001) after 3 months of acupoint massage treatment and 3.04 (95% C.I. [2.43-3.64], p < 0.00001) after 6 months of treatment. They also calculated the merged MD of the Wechsler Memory Scale-Revised Chinese version after 6 months of acupoint massage. Visual Reproduction was 2.95 (95% C.I. [1.30-4.60], p = 0.0005), Associate Learning was 1.89 (95% C.I. [1.41-2.37], p < 0.00001), Logical Memory was 2.85 (95% C.I. [2.06-3.63], p < 0.00001), and Digit Span was 3.16 (95% C.I. [2.59-3.73], p < 0.00001). The Cochrane Handbook for Systematic Reviews of Interventions was used to rate the quality of the studies, which was moderate overall. The findings suggested that

    Falls in older people are a common problem, often leading to considerable morbidity. However, the overall effect of exercise interventions on fall prevention in care facilities remains controversial. To evaluate the effectiveness of exercise interventions on the rate of falls and number of fallers in care facilities. A meta-analysis was conducted of randomized controlled trials published up to December 2014. Eight databases were searched including Ovid-Medline, Embase, CINAHL, Cochrane Library, KoreaMed, KMbase, KISS, and KisTi. Two investigators independently extracted data and assessed study quality. Twenty-one studies were selected, that included 5,540 participants. Fifteen studies included exercise as a single intervention, whereas the remaining six included exercise combined with two or more fall interventions tailored to each resident's fall risk (i.e., medication review, environmental modification or staff education). Meta-analysis showed that exercise had a preventive effect on the rate of falls (risk ratio [RR] 0.81, 95% CI 0.68-0.97). This effect was stronger when exercise combined with other fall interventions on the rate of falls (RR 0.61, 95% CI 0.52-0.72) and on the number of fallers (RR 0.85, 95% CI 0.77-0.95). Exercise interventions including balance training (i.e., gait, balance, and functional training; or balance and strength) resulted in reduced the rate of falls. Sensitivity analyses indicated that exercise interventions resulted in reduced numbers of recurrent fallers (RR 0.71, 95% CI 0.53-0.97). This review provides an important basis for developing evidence-based exercise intervention protocols for older people living in care facilities. Exercise programs, which are combined with tailored other fall interventions and challenge balance training to improve balance skills, should be applied to frail older people with functional limitations in institutional settings. © 2016 Sigma Theta Tau International.

    Based on radiological reports, the percentage of breast cancers visualized as incidental findings in routine CT examinations is estimated at ≤2%. In view of the rising number of CT examinations and the high prevalence of breast cancer, it was the goal of the present study to verify the frequency and image morphology of false-negative senological CT findings. All first contrast-enhanced CT examinations of the chest in adult female patients carried out in 2012 were retrospectively included. A senior radiologist systematically assessed the presence of breast lesions on all CT images using the BI-RADS system. All BI-RADS ≥3 notations were evaluated by a second senior radiologist. A consensus was obtained in case of differing BI-RADS assessments. Reference diagnoses were elaborated based on all available clinical, radiological and pathological data. The findings of the CT reports were classified according to the BI-RADS system and were compared with the retrospective consensus findings as well as with the reference diagnoses. The range of indications comprised a broad spectrum including staging and follow-up examinations of solid tumors/lymphoma (N = 701, 59.9 %) and vascular (190, 16.2 %), inflammatory (48, 4.1 %) and pulmonologic (22, 1.9 %) issues. BI-RADS 1/2 classifications were present in 92.5 % and BI-RADS 6 classifications were assessed in 1.7 % of the 1170 included examinations. 68 patients (5.8 %) had at least one lesion retrospectively classified as BI-RADS 3 - 5. The histological potential was known in 57 of these lesions as benign (46, 3.9 %) or malignant (11, 0.9 %). 13 BI-RADS 4/5 consensus assessments (1.1 %) were false-positive. 2 of the 10 lesions classified as being malignant based on the further clinical and radiological course were not mentioned in the written CT reports (0.2 %). Both false-negative CT reports were therapeutically and prognostically irrelevant. The relative frequency of BI-RADS 3 - 5 findings was 5.8 %. It reflects the situation

    The objective of this study was to investigate major dietary patterns among older Korean adults through cluster analysis and to determine an association between dietary patterns and cognitive function. This is a cross-sectional study. The data from the Korean Multi-Rural Communities Cohort Study was used. Participants included 765 participants aged 60 years and over. A quantitative food frequency questionnaire with 106 items was used to investigate dietary intake. The Korean version of the MMSE-KC (Mini-Mental Status Examination-Korean version) was used to assess cognitive function. Two major dietary patterns were identified using K-means cluster analysis. The "MFDF" dietary pattern indicated high consumption of Multigrain rice, Fish, Dairy products, Fruits and fruit juices, while the "WNC" dietary pattern referred to higher intakes of White rice, Noodles, and Coffee. Means of the total MMSE-KC and orientation score of the participants in the MFDF dietary pattern were higher than those of the WNC dietary pattern. Compared with the WNC dietary pattern, the MFDF dietary pattern showed a lower risk of cognitive impairment after adjusting for covariates (OR 0.64, 95% CI 0.44-0.94). The MFDF dietary pattern, with high consumption of multigrain rice, fish, dairy products, and fruits may be related to better cognition among Korean older adults.

    Motor-vehicle crashes were the second leading cause of injury death for adults aged 65-84years in 2014. Some older drivers choose to self-regulate their driving to maintain mobility while reducing driving risk, yet the process remains poorly understood. Data from 729 older adults (aged ≥60years) who joined an older adult ride service program between April 1, 2010 and November 8, 2013 were analyzed to define and describe classes of driving self-regulation. Latent class analysis was employed to characterize older adult driving self-regulation classes using driving frequency and avoidance of seven driving situations. Logistic regression was used to explore associations between characteristics affecting mobility and self-regulation class. Three classes were identified (low, medium, and high self-regulation). High self-regulating participants reported the highest proportion of always avoiding seven risky driving situations and the lowest driving frequency followed by medium and low self-regulators. Those who were female, aged 80years or older, visually impaired, assistive device users, and those with special health needs were more likely to be high self-regulating compared with low self-regulating. Avoidance of certain driving situations and weekly driving frequency are valid indicators for describing driving self-regulation classes in older adults. Understanding the unique characteristics and mobility limitations of each class can guide optimal transportation strategies for older adults. Published by Elsevier Ltd.

    2018-02-01

    Full Text Available With the high older-related accident ratio and increasing population aging problem, understanding older drivers' driving behaviors has become more and more important for building and improving transportation system. This paper examines older driver's driving behavior which includes road selection, left/right turn and driving speed. A two-month experiment of 108 participants was carried out in Aichi Prefecture, Japan. Since apparently contradictory statements were often drawn in survey-based or simulators-based studies, this study collected not only drivers' basic information but also GPS data. Analysis of road selection demonstrates that older drivers are reluctant to drive on expressway not only in short trips but also in long trips. The present study did not find significant difference between older drivers and others while turning at the intersections. To investigate the impact factors on driving speed, a random-effects regression model is constructed with explanatory variables including age, gender, road types and the interaction terms between age and road types. Compared with other variables, it fails to find that age (60 years old or over has significant impact on driving speed. Moreover, the results reflect that older drivers drive even faster than others at particular road types: national road and ordinary municipal road. The results in this study are expected to help improve transportation planning and develop driving assistance systems for older drivers.

    Previous meta-analyses have found that exercise prevents falls in older people. This study aimed to test whether this effect is still present when new trials are added, and it explores whether characteristics of the trial design, sample or intervention are associated with greater fall prevention effects. Update of a systematic review with random effects meta-analysis and meta-regression. Cochrane Library, CINAHL, MEDLINE, EMBASE, PubMed, PEDro and SafetyLit were searched from January 2010 to January 2016. We included randomised controlled trials that compared fall rates in older people randomised to receive exercise as a single intervention with fall rates in those randomised to a control group. 99 comparisons from 88 trials with 19 478 participants were available for meta-analysis. Overall, exercise reduced the rate of falls in community-dwelling older people by 21% (pooled rate ratio 0.79, 95% CI 0.73 to 0.85, pexercise programmes that challenged balance and involved more than 3 hours/week of exercise. These variables explained 76% of the between-trial heterogeneity and in combination led to a 39% reduction in falls (incident rate ratio 0.61, 95% CI 0.53 to 0.72, pExercise also had a fall prevention effect in community-dwelling people with Parkinson's disease (pooled rate ratio 0.47, 95% CI 0.30 to 0.73, p=0.001, I 2 65%, 6 comparisons) or cognitive impairment (pooled rate ratio 0.55, 95% CI 0.37 to 0.83, p=0.004, I 2 21%, 3 comparisons). There was no evidence of a fall prevention effect of exercise in residential care settings or among stroke survivors or people recently discharged from hospital. Exercise as a single intervention can prevent falls in community-dwelling older people. Exercise programmes that challenge balance and are of a higher dose have larger effects. The impact of exercise as a single intervention in clinical groups and aged care facility residents requires further investigation, but promising results are evident for people with Parkinson

    Full Text Available BACKGROUND: Early discrimination between transient and persistent par-solid ground-glass nodules (PSNs at CT is essential for patient management. The objective of our study was to retrospectively investigate the value of texture analysis in differentiating pulmonary transient and persistent PSNs in addition to clinical and CT features. METHODS: This retrospective study was performed with IRB approval and a waiver of the requirement for patients' informed consent. From January 2007 to October 2009, we identified 77 individuals (39 men and 38 women; mean age, 55 years with 86 PSNs on thin-section chest CT. Thirty-nine PSNs in 31 individuals were transient and 47 PSNs in 46 patients were persistent. The clinical, CT, and texture features of PSNs were evaluated. To investigate the additional value of texture analysis in differentiating transient from persistent PSNs, logistic regression analysis and C-statistics were performed. RESULTS: Between transient and persistent PSNs, there were significant differences in age, gender, smoking history, and eosinophil count among the clinical features. As for thin-section CT features, there were significant differences in lesion size, solid portion size, and lesion multiplicity. In terms of texture features, there were significant differences in mean attenuation, skewness of whole PSN, attenuation ratio of whole PSN to inner solid portion, and 5-, 10-, 25-, 50-percentile CT numbers of whole PSN. Multivariate analysis revealed eosinophilia, lesion size, lesion multiplicity, mean attenuation of whole PSN, skewness of whole PSN, and 5-percentile CT number were significant independent predictors of transient PSNs. (P<0.05 C-statistics revealed that texture analysis incorporating clinical and CT features (AUC, 92.9% showed significantly higher differentiating performance of transient from persistent PSNs compared with the clinical and CT features alone (AUC, 79.0%. (P =  0.004. CONCLUSION: Texture analysis of

    Full Text Available Introduction: Traumatic injury is a leading cause of death and disability in adults ≥ 65 years old, but there are few epidemiological studies addressing this issue. The aim of this study was to assess how characteristics of blunt traumatic injuries in adults ≥ 65 vary by age. Methods: Using data from the a single-state trauma registry, this retrospective cohort study examined injured patients ≥ 65 admitted to all Level I and Level II trauma centers in Pennsylvania between 2011 and 2014 (n=38,562. Patients were stratified by age into three subgroups (age 65-74; 75-84; ≥85. We compared demographics, injury, and system-level across groups. Results: We found significant increases in the proportion of female gender, (48.6% vs. 58.7% vs. 67.7%, white race (89.1% vs. 92.6% vs. 94.6%, and non-Hispanic ethnicity (97.5% vs. 98.6% vs. 99.4% across advancing age across age groups, respectively. As age increased, the proportion of falls (69.9% vs. 82.1% vs. 90.3%, in-hospital mortality (4.6% vs. 6.2% vs. 6.8%, and proportion of patients arriving to the hospital via ambulance also increased (73.6% vs. 75.8% vs. 81.1%, while median injury severity plateaued (9.0% all groups and the proportion of Level I trauma alerts (10.6% vs. 8.2% vs. 6.7% decreased. We found no trend between age and patient transfer status. The five most common diagnoses were vertebral fracture, rib fracture, head contusion, open head wound, and intracranial hemorrhage, with vertebral fracture and head contusion increasing with age, and rib fracture decreasing with age. Conclusion: In a large cohort of older adults with trauma (n= 38,000, we found, with advancing age, a decrease in trauma alert level, despite an increase in mortality and a decrease in demographic diversity. This descriptive study provides a framework for future research on the relationship between age and blunt traumatic injury in older adults.

    To analyse retrospectively the indications, technique and results of radiologically induced gastrostomies or enterostomies. Radiologically assisted gastrostomies or enterostomies were induced in 90 patients, mostly with high grade obstructions due to head and neck tumours or oesophageal tumours. 19/90 patients had had previous resection of the oesophagus or gastric operations. A catheter was successfully introduced in all patients. In 11/90 patients this was followed by a two-stage procedure. In 16/90 patients puncture was performed under CT control because of some anatomical peculiarity. Serious complication occurred in 9/90 patients but in only one was surgery necessary. There were no deaths resulting from the procedure but mortality after 30 days was 6.7%. Radiologically assisted gastrostomies or enterostomies are a reliable and effective form of treatment even amongst difficult patients. The results and complications are comparable to those from endoscopic procedures. (orig.) [de

    Full Text Available OBJECTIVE: here have been tremendous changes in treatment and follow-up of patients with chronic myeloid leukemia (CML in the last decade. Especially, regular publication and updating of NCCN and ELN guidelines have provided enermous rationale and base for close monitorization of patients with CML. But, it is stil needed to have registry results retrospectively to evaluate daily CML practices. METHODS: In this article, we have evaluated 1133 patients’ results with CML in terms of demographical features, disease status, response, resistance and use of second-generation TKIs. RESULTS: The response rate has been found relatively high in comparison with previously published articles, and we detected that there was a lack of appropriate and adequate molecular response assessment. CONCLUSION: We concluded that we need to improve registry systems and increase the availability of molecular response assessment to provide high-quality patient care.

    2012-01-01

    Purpose: An evaluation of dose–response relationship and an attempt to define predictive factors. Methods and Materials: A total of 137 cases of painful vertebral hemangioma irradiations (101 patients). Fraction dose (fd) varied from 2 to 15 Gy (123 fractionated and 14 radiosurgical treatments), and total dose (TD) from 8 to 30 Gy (111 cases irradiated with fd of 2 GY to TD of 24 Gy). We evaluated pain relief, changes in analgesic requirements, and reossification. Results: Means of pain relief 1, 6, 12, and 18 months after radiotherapy (defined as a decrease of primary pain level expressed in percent) were 60.5%, 65.4%, 68.3%, and 78.4%, respectively. Proportion of patients with no need for analgesics and patients using tramadol were 39%, 40%, 44%, 57%, and 20%, 17%, 22%, and 11% in these times. The proportion of patients experiencing complete/partial pain relief changed from 36/48% 1 month, to 64/22% 1.5 years after radiotherapy. No impact of radiotherapy on reossification was found. The positive impact of fd and TD increase for analgesics uptake reduction and pain relief was found. An increase of the fd by 1 Gy results in 27% chance of analgesics uptake reduction and 3.8% reduction of pain, whereas 14% analgesics uptake reduction and 2.2% of pain reduction in case of the TD. The predictive factors improving results were found: female gender, older age, better performance states (the chance of the lower analgesic treatment decreases over 2.5 times in comparison to the higher Zubrod degree), bigger Hb concentration, shorter symptoms duration and lower analgesics uptake before radiotherapy. Conclusions: The obtained data support the efficacy of radiotherapy in improving pain secondary to vertebral hemangioma, with the degree of pain amelioration being related to increasing fd and TD. The positive predictive factors were defined: female gender, older age, better performance status, increased Hb concentration, shorter symptoms duration, and lower analgesics uptake

    To determine the criteria for postoperative mechanical ventilation after thymectomy in patients with Myasthenia Gravis. Retrospective study. Teritiary care centre. 77 Myasthenia gravis patients operated for thymectomy were studied. After obtaining clearance from Institutional ethics committee, medical records of 77 patients with MG, who were operated for thymectomy between January 2005 and December 2015 were reviewed in a retrospective manner. Perioperative variables collected from the patient records were demographic data, duration of the disease, Osserman and Genkin classification, Anti-acetylcholine antibody (AChR) positivity, preoperative daily dose of drug, history of preoperative myasthenic crisis, preoperative vital capacity, technique of anesthesia, drugs used for anesthesia, perioperative complications, and duration of postoperative mechanical ventilation. The patients were divided into two groups, group I and group II consisting of those who required postoperative ventilation for 300 minutes, respectively. The determinants of prolonged postoperative ventilation were studied. The requirement of mechanical ventilation was higher in patients with higher Osserman's grade of myasthenia gravis. Duration of the disease had no effect on the duration of mechanical ventilation in myasthenic patients post thymectomy (p = 0.89). The patients with a preoperative history of myasthenic crisis had a requirement for prolonged mechanical ventilation (p=0.03). Patients with preoperative vital capacity mechanical ventilation with p values mechanical ventilation (p=0.026). Preoperative dose of pyridostigmine and the choice of continuation or discontinuation of antcholinesterases on the day of surgery had no influence on the duration of mechanical ventilation (p value of 0.19 and 0.36 respectively). Epidural analgesia intra and postoperatively significantly reduced the requirement of mechanical ventilation (p=0.006). The predictors of postoperative ventilation in myasthenic

    AIM: To retrospectively evaluate the prevalence of lymph nodes of the hepato-duodenal ligament in a group of patients with chronic liver disease of various aetiologies and to investigate what clinical, aetiological and laboratory data may lead to their appearance. MATERIALS AND METHODS: One thousand and three patients (554 men, 449 women) were studied, including 557 with chronic hepatitis and 446 with liver cirrhosis. The presence of lymph nodes near the trunk of the portal vein, hepatic artery, celiac axis, superior mesenteric vein and pancreas head was investigated using ultrasound. RESULTS: Lymph nodes were detected in 394 out of the 1003 study patients (39.3%); their number ranged from one to four, with a diameter ranging between 0.8 and 4 cm. The highest prevalence was in the subgroup of patients with primary biliary cirrhosis (87.5%), followed by patients with hepatitis C virus (HCV; 42%), patients with HCV and hepatitis B virus (HBV; 41.3%), autoimmune hepatitis (40%), and HBV alone (21.2%). In the alcoholic and idiopathic subgroups prevalence was 9.5%, while in the non-alcoholic steatohepatitis and haemochromatosis subgroups it was 0%. HCV RNA was present in 97 out of 103 lymph node-positive patients and in 141 out of 168 lymph node-negative HCV-negative patients (p<0.003). Lymphadenopathy frequency increased as the liver disease worsened ({chi}{sup 2} MH=74.3; p<0.0001). CONCLUSION: Despite the limitations of a retrospective study, our data indicate a high prevalence of lymphadenopathy in liver disease patients; ultrasound evidence of lymph nodes of the hepato-duodenal ligament in a given liver disease may most likely suggest a HCV or an autoimmune aetiology and a more severe histological picture.

    Follicular lymphoma (FL) is the most common type of non-Hodgkin lymphoma (NHL), with indolent progression. Several treatment options are selected, based not only on disease status, quality of life (QOL), and age of patient, but also on recent increasing medical costs. We retrospectively analysed the first-line treatment of FL with regard to treatment outcomes and medical economics, and discuss the appropriate strategies for FL. Data on a total of 69 newly-diagnosed patients with FL was retrospectively collected from 2001 to 2015. The median age of the patients was 60 years and the median follow-up was 58 months. A total of 25 cases with FL were treated with R monotherapy, and 28 cases were treated with R-CHOP as first-line treatment. The factors affecting the decision of physicians to use R or R-CHOP treatment were serum level of lactate dehydrogenase (LDH) and disease stage. The first-line treatment-associated survival did not show any statistical differences between R and R-CHOP. The average hospitalization and average of all medical costs during the first-line treatment were 4.1 days (R) versus 55.7 days (R-CHOP), and JPY 1,707,693 (USD 15,324) (R) versus JPY 2,136,117 (USD 19,170) (R-CHOP), respectively. R monotherapy for patients whose diseases show low tumor burden and who are not candidates for local treatment has benefits as a first-line treatment compared to R-CHOP, based on the patients' QOL and medical economics.

    We retrospectively evaluated the pretreatment radiological presentation and the clinicoradiological outcome at the completion of 1 year chemotherapy in osteoarticular tuberculosis of hip in children to prognosticate correlation between them. We retrospectively analyzed the clinical and plain radiographic findings in 27 patients with an age of 12 years or younger in whom hip tuberculosis was diagnosed and treated between 2006 and 2010. The diagnosis was based on histopathology in 14 and clinicoradiological basis in 13 patients. The pre and post treatment plain radiographs were evaluated according to Shanmugasundaram radiological classification and our observations regarding unclassified cases which were not fit in this classification were suggested. The functional outcome at the completion of chemotherapy was assessed using modified Moon's criteria. The male female ratio was 11:16. The left hip was involved more frequently than the right (17:10). The average age was 7.37 years (range, 2-12 years). In the pretreatment radiographs, 9 hips were normal, 6 traveling, 4 dislocating, 1 protrusio acetabuli, 3 atrophic and 4 unclassified types (3 triradiate; 1 pseudarthrosis coxae). There were no Perthes and mortar pestle at the initial presentation. Posttreatment, the types changed to 9 normal, 3 Perthes, 1 protrusio acetabuli, 1 atrophic, 4 mortar pestle and 9 unclassified types (3 triradiate, 3 pseudarthrosis coxae and 3 ankylosed). There were 37% excellent, 18.5% good, 26% fair and 18.5% poor results. The prognosis was best with initial "triradiate" and normal types and worst with posttreatment atrophic and "ankylosed" types. The Shanmugasundaram radiological types accurately predict prognosis only in normal types and "triradiate" pattern. The functional outcome is independent of radiological morphology of the hip in smaller children.

    Background and purpose: To evaluate the prognostic significance of response to external beam radiation (EBRT) in predicting the clinical outcomes in stage IIIB cancer cervix and to find out factors affecting response to EBRT. Patients and methods: This retrospective study included 556 patients of cancer cervix stage IIIB treated between 1996 and 2001 with EBRT (46 Gy/23fx/4.5 weeks) followed by intracavitary radiotherapy (ICRT). At the end of EBRT, response to EBRT was grouped as 'no gross residual tumor'(NRT) or 'gross residual tumor'(GRT). Results: Follow up ranged from 2 to 93 months with a median of 36 months. Median dose to point A was 81 Gy. At the end of EBRT, 393 patients (70.7%) attained NRT response. NRT responders had significantly better 5 year pelvic control, disease free survival (DFS) and overall survival (OS) than those who had a GRT response (75.6 vs. 54.6%; 60.6 vs. 31.9% and 62.6 vs. 33.7%, respectively; all P values <0.0001). Apart from response to EBRT, overall treatment time also has emerged as an independent factor to affect all clinical outcomes in multivariate analysis but age had significant impact on pelvic control only. Age was the only factor, which significantly influenced the response to EBRT in univariate as well as multivariate analysis (P=<0.001, OR=1.973, 95% C.I. 1.357-2.868). Patients with age more than 50 years had more NRT response (77%) than patients with age less than 50 years (63.8%). Conclusions: Patients who attain NRT response to EBRT will have an impressive long term pelvic control, DFS and OS in stage IIIB cancer cervix. Older patients (≥50 years) attain significantly higher NRT rates than younger patients

    Full Text Available Cutaneous melanoma is the most life-threatening form of skin cancer. Although advanced melanoma is often considered as incurable, if detected and excised early, the prognosis is promising. Today, clinicians use computer vision in an increasing number of applications to aid early detection of melanoma through dermatological image analysis (dermoscopy images, in particular. Colour assessment is essential for the clinical diagnosis of skin cancers. Due to this diagnostic importance, many studies have either focused on or employed colour features as a constituent part of their skin lesion analysis systems. These studies range from using low-level colour features, such as simple statistical measures of colours occurring in the lesion, to availing themselves of high-level semantic features such as the presence of blue-white veil, globules, or colour variegation in the lesion. This paper provides a retrospective survey and critical analysis of contributions in this research direction.

    This study evaluated the applicability of computer-aided diagnosis by retrospective analysis of GLCM algorithm based on cytopathological diagnosis of normal and malignant nodules in thyroid ultrasound images. In the experiment, the recognition rate and ROC curve of thyroid malignant nodule were analyzed using 6 parameters of GLCM algorithm. Experimental results showed 97% energy, 93% contrast, 92% correlation, 92% homogeneity, 100% entropy and 100% variance. Statistical analysis showed that the area under the curve of each parameter was more than 0.947 (p = 0 .001) in t he ROC curve, which was s ignificant in the recognition of thyroid malignant nodules. In the GLCM, the cut-off value of each parameter can be used to predict the disease through analysis of quantitative computer-aided diagnosis.

    The present study examined the intersectionality of stigma across varying groups of older persons living with HIV (PWH). Four focus groups of older PWH (gay/bisexual men, heterosexual men, heterosexual and bisexualwomen, and Spanish-speaking) were audio-recorded and transcribed. Inductive thematic text analysis was used to identify qualitative themes. Five major themes emerged from the data: 1) disclosure of HIV status; 2) types of stigma experienced; 3) discrimination experienced; 4) other outcomes associated with experiencing stigma; and 5) influence of aging on social isolation experienced due to stigma. Findings indicate women did not suffer from the intersection of stigmas. Other groups suffered from the intersection of stigma due to HIV status and age (gay/bisexual males); HIV status and perceived stigma of sexual orientation or drug use (heterosexual males); and HIV status and culture/ethnicity (Spanish-speaking). Results indicate that many at-risk groups, including heterosexual men, homosexual men, and Spanish-speaking individuals, experience an intersection of stigma between aging and their sexuality, HIV status, or real or perceived drug use. Results highlight the need for HIV support, especially social support, to address intersection of stigmas for unique groups of individuals disproportionately affected by HIV.

    Organizational volunteering has been touted as an effective strategy for older adults to help themselves while helping others. Extending previous reviews, we carried out a meta-analysis of the relation between organizational volunteering by late-middle-aged and older adults (minimum age = 55 years old) and risk of mortality. We focused on unadjusted effect sizes (i.e., bivariate relations), adjusted effect sizes (i.e., controlling for other variables such as health), and interaction effect sizes (e.g., the joint effect of volunteering and religiosity). For unadjusted effect sizes, on average, volunteering reduced mortality risk by 47%, with a 95% confidence interval ranging from 38% to 55%. For adjusted effect sizes, on average, volunteering reduced mortality risk by 24%, with a 95% confidence interval ranging from 16% to 31%. For interaction effect sizes, we found preliminary support that as public religiosity increases, the inverse relation between volunteering and mortality risk becomes stronger. The discussion identifies several unresolved issues and directions for future research. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    This study examined the effect of health worry (i.e., cognitive aspect of anxiety resulting from concern for health) on walking difficulty in a nationally representative sample (N = 7,527) of older adults (M age = 76.83 years). The study further tested whether physical activity mediates the effect of health worry on walking difficulty in a 6-year follow-up design. Results of a mediation analysis using structural equation modeling showed that people with a high degree of health worry engaged in less physical activity (beta = -.24, p < .001), and people who participated in less physical activity were more likely to report walking difficulty at the 6-year follow-up (beta = -.22, p < .001). There was a significant indirect effect from health worry to walking difficulty through physical activity (beta = .05, p < .001), controlling for demographic, psychosocial, and health related factors. Results suggested that inducing threat and worry may not be effective for physical activity promotion in the older population. More promising coping and regulation strategies are discussed.

    This meta-analysis examined the mean sleep duration and patterns in Chinese older adult population. A literature search was systematically conducted covering major English (PubMed, Embase and PsycINFO) and Chinese (Chinese National Knowledge Infrastructure (CNKI), WanFang and SinoMed) databases. Data in studies with the mean and standard deviation of sleep duration and/or the proportion of short and long sleep durations in Chinese older adults were extracted and pooled using random-effects models. Subgroup analyses were conducted according to gender, region, area, survey time and sample size. A total of 36 studies with 150,616 subjects were included for analyses. The pooled mean sleep duration of 21 studies with available data was 6.82 hours/day (95% CI: 6.59-7.05 hours/day). The estimated proportions of sleep duration 8 hours/day) and 17.6% (95% CI: 12.4%-22.9%) (>9 hours/day). Given the adverse effects of unhealthy sleep patterns, health professionals should pay more attention to sleep patterns in this population in China.

    Full Text Available Abstract Background Use of the atypical antipsychotic sertindole was suspended for four years due to safety concerns. During the suspension, the regulatory authorities required further studies, including this one, to be conducted. The purpose of this study was to determine if a subset of patients with psychotic illness exists which particularly benefits from sertindole treatment after failure of other antipsychotic drugs, including atypical antipsychotics. Methods This was a retrospective single-arm observational crossover study of 344 patients, who served as their own controls. Patients mainly from the Sertindole Safety Study who had shown good response to sertindole, and who had followed up to four alternating six month periods of treatment with sertindole and other antipsychotics, were included. (In Period 1 patients took non-sertindole treatment, in Period 2, sertindole was taken, in Period 3, patients reverted to non-sertindole treatment, and in Period 4, sertindole was taken again. Patient records for each period of treatment were assessed for objective data: number and duration of hospitalizations due to worsening of psychotic symptoms; the amount of self-harming behaviour; indicators of social status. Retrospective evaluation of changes in clinical symptoms from the patients' records was also conducted. Dates and reasons for stopping and/or switching medication were also recorded. Results There was improvement in all objective measured parameters during the periods of sertindole treatment. In particular, the average number of hospitalizations per year due to worsening of psychotic symptoms was reduced in the following way in the group studied over four treatment periods: Period 1 (non-sertindole treatment 3.4; Period 2 (sertindole treatment 1.0; Period 3 (non-sertindole treatment 2.0; Period 4 (sertindole treatment 1.8. The duration of hospitalizations also decreased significantly during the periods of sertindole treatment. Results

    Monopolar radiofrequency skin heating coupled with cryogen cooling of facial skin for skin tightening has been utilized on over 10,000 patients since 2002. In order to establish the actual rate and degree of side effects in our clinical experience, a retrospective chart review was performed. Charts and clinical images of over 600 consecutive patient treatments between May 2002 and June 2006 using a monopolar radiofrequency device (Thermacool, Thermage, Haywood, CA) for skin tightening at the Maryland Laser, Skin and Vein Institute were retrospectively reviewed. The primary presentation for treatment was skin laxity of the lower face. Treatment was delivered with a 1-cm2 standard tip at fluences of 81 to 124 J/cm2 (level of 12.5 to 15), a 1-cm2 "fast" tip at fluences of 62 to 109 J/cm2 (level of 72.0 to 76.0), a 1.5-cm2 "big fast" tip at fluences of 75 to 130 J/cm2 (level of 61.5 to 65), and a 3-cm2 "bigger" tip at equivalent fluences as each became available. As treatment algorithms evolved over 4 years, the algorithm of multiple passes at lower fluence associated with better clinical outcomes and greater patient acceptance has been adopted. The most common immediate and expected clinical effects were erythema and edema lasting less than 24 hours, although 6 patients reported edema lasting for up to 1 week. There were no permanent side effects. In total, 2.7% of treatments resulted in temporary side effects, the most significant of which was a slight depression on the cheek (n = 1), which completely resolved within 3.5 months. Other side effects included localized areas of acneiform subcutaneous erythematous papules (n = 4) and a linear superficial crust (n = 1) with the original tip, all of which resolved within 1 week. One patient reported small erythematous subcutaneous nodules resolving in 17 days. Tenderness of the neck lasting from 2 weeks (n = 2) to 3 weeks (n = 1) was also reported. Our data, obtained in an office setting without injectable anesthetic or i

    Full Text Available Aim: In this study, we aimed to evaluate the demographic and histopathological characteristics and response to medications in children with idiopathic nephrotic syndrome in Turkey. Methods: We reviewed medical records of patients older than one year, who were newly diagnosed with nephrotic syndrome and had been followed for at least one year in our department between November 1994 and March, 2013. Results: A total of 289 children (169 boys were included in the study. Fifty theree patients (18.4% were with steroid-resistant nephrotic syndrome, 33 (11.4% with frequently relapsing nephrotic syndrome and 53 (18.4% were with steroid-dependent nephrotic syndrome. Cyclosporine A (CsA, cyclophosphamide, mycophenolate mofetil, levamisole, azathioprine, and rituximab were used as steroid-sparing agents in some patients. The number of patients who were responder to steroid and to CsA was similar. Majority of patients with steroid-resistant nephrotic syndrome were also resistant to mycophenolate mofetil and CsA. Conclusion: There was a high prevalence of minimal change disease based on kidney biopsy especially in boys younger than six years of age and response to steroid and CsA was almost similar.

    Full Text Available Background: Hypokalemic paralysis is characterized by episodes of acute muscle weakness associated with hypokalemia. In this study, we evaluated the possible etiological factors in patients of hypokalemic paralysis. Materials and Methods: We reviewed the records of 29 patients who were admitted with a diagnosis of hypokalemic paralysis. Modified Guillain-Barre΄ Syndrome disability scale was used to grade the disability. Results: In this study, 15 (51.7% patients had secondary causes of hypokalemic paralysis and 14 patients (42.3% had idiopathic hypokalemic paralysis. Thyrotoxicosis was present in six patients (20.6%, dengue infection in four patients (13.7%, distal renal tubular acidosis in three patients (10.3%, Gitelman syndrome in one patient (3.4%, and Conn′s syndrome in one patient (3.4%. Preceding history of fever and rapid recovery was seen in dengue infection-induced hypokalemic paralysis. Approximately 62% patients had elevated serum creatinine phosphokinase. All patients had recovered completely following potassium supplementation. Patients with secondary causes were older in age, had significantly more disability, lower serum potassium levels, and took longer time to recover. Conclusion: In conclusion, more than half of patients had secondary causes responsible for hypokalemic paralysis. Dengue virus infection was the second leading cause of hypokalemic paralysis, after thyrotoxicosis. Presence of severe disability, severe hypokalemia, and a late disease onset suggested secondary hypokalemic paralysis.

    Spinal fusion is used for treatment of spinal deformities, degeneration, infection, malignancy, and trauma. Reduction of motion enables osseous fusion and permanent stabilization of segments, compromised by loosening of the pedicle screws (PS). Deep implant infection, biomechanical, and chemical mechanisms are suspected reasons for loosening of PS. Study objective was to investigate the frequency and impact of deep implant infection on PS loosening. Intraoperative infection screening from wound and explanted material sonication was performed during revision surgeries following dorsal stabilization. Case history events and factors, which might promote implant infections, were included in this retrospective survey. 110 cases of spinal metal explantation were included. In 29.1% of revision cases, infection screening identified a germ, most commonly Staphylococcus (53.1%) and Propionibacterium (40.6%) genus. Patients screened positive had a significant higher number of previous spinal operations and radiologic loosening of screws. Patients revised for adjacent segment failure had a significantly lower rate of positive infection screening than patients revised for directly implant associated reasons. Removal of implants that revealed positive screening effected significant pain relief. Chronic implant infection seems to play a role in PS loosening and ongoing pain, causing revision surgery after spinal fusion. Screw loosening and multiple prior spinal operations should be suspicious for implant infection after spinal fusion when it comes to revision surgery.

    Purpose: The purpose of this study was to evaluate the safety and clinical value of MR-guided biopsies in an open 0.2 T low-field system. Materials and methods: A total of 322 patients with suspicious lesions of different body regions were biopsied in a low-field MRI system (0.2 T, Concerto, Siemens). The procedures were guided using T1-weighted Flash sequences (TR/TE = 100/9; 70 ). The lesions were repeatedly biopsied using the coaxial technique with a 15-gauge (diameter 2 mm) puncture needle. Complications and biopsy findings were analyzed retrospectively. Results: In all cases the biopsy procedures were successfully performed with MR guidance. In 298 patients diagnosis was able to be confirmed on the basis of the probes. The clinical follow-up showed that in 24 patients the lesions were missed by MR-guided biopsy. From this a sensitivity of 86%, a specificity of 87% and an accuracy of 93% were calculated. In two patients major complications were observed (morbidity rate 0.6%). Conclusion: MR-guided biopsy can be performed safely and precisely in a low-field MR system and are a supplement to US or CT-guided biopsies. (orig.)

    Full Text Available Background : Maxillofacial fractures can lead to substantial long-term functional, esthetic and psychological complications. Aim : The aim of this study is to evaluate these injuries in a Turkish Iranian population. Materials and Methods : A retrospective study of 170 patients with 210 maxillofacial fractures admitted to the emergency department of a central referral emergency hospital in the area over a 5 year period is presented. Patients′ data included demographic information, etiology, site and associated injuries and complications. Results : Road traffic accident was the commonest cause (40% and the age group of 21-30 comprised the biggest group (30%. Mandibular fractures outnumbered midface fractures (150vs.60. Ramus (21.5% and zygoma (26.5% were the commonest fracture regions respectively in mandible and midface. Male: female ratio was 3.8:1 Almost half of patients (46% had sustained associated injuries most of which was soft tissue laceration of the face (17.5%. 22 patient (13% had associated complication and the hemorrhage was the commonest form of that (9%. Conclusion : It seems that road traffic accidents continue to be the leading cause of maxillofacial fractures and there is an urgent need to implement enhanced regulations and monitoring on motor vehicular traffic.

    Headache is a common symptom, that can be extremely disabling, affecting 26 million of patients only in Italy. ICHD-II has reported two categories: "primary headaches" and "secondary headaches". Temporomandibular joint disorders can lead to a secondary headaches. We want to evaluate the prevalence and clinical features of headache among a series of patients having temporomandibular joint disorders and we illustrate the evolution of headache following medical treatament of temporomandibular joint (TMJ) disorders. This is a retrospective study carried out on chart review of 426 consecutive patients with various degrees of temporomandibular disorders and treated with medical devices from 2007 to 2011. Headache was reported by 73 patients (17.14%). Headache was observed in 36 of 51 patients with lock and in 32 out of 130 patients with mandibular deflections (Table I). The remaining 5 patients with headache had articular noise. Headache is not a rare finding in a population with temporomandibular dysfunctions and is more often a tension-type rather than trigeminal headache.

    Full Text Available Objectives. The propofol infusion syndrome (PRIS, a rare, often fatal, condition of unknown etiology, is defined by development of lipemic serum, metabolic acidosis, rhabdomyolysis, hepatomegaly, cardiac arrhythmias, and acute renal failure. Methods. To identify risk factors for and biomarkers of PRIS, a retrospective chart review of all possible PRIS cases during a 1-year period was conducted at a level 1 trauma hospital in ICU patients over 18 years of age receiving continuous propofol infusions for ≥3 days. Additional study inclusion criteria included vasopressor support and monitoring of serum triglycerides and creatinine. Results. Seventy-two patients, 61 males (84.7% and 11 females (15.3%, satisfied study inclusion criteria; and of these, 3 males met the study definition for PRIS, with 1 case fatality. PRIS incidence was 4.1% with a case-fatality rate of 33%. The mean duration of propofol infusion was 6.96 days. A positive linear correlation was observed between increasing triglyceride levels and infusion duration, but no correlation was observed between increasing creatinine levels and infusion duration. Conclusions. Risk factors for PRIS were confirmed as high dose infusions over prolonged periods. Increasing triglyceride levels may serve as reliable biomarkers of impending PRIS, if confirmed in future investigations with larger sample sizes.

    Paraneoplastic neurological syndromes (PNS) constitute a challenging diagnostic problem, as the underlying tumour often remains unidentified for a long time, even with frequent conventional diagnostic procedures. For appropriate patient management timely identification of the tumour is critical. We evaluated the value of 18 F-FDG-PET/CT in the investigation of PNS. The case notes of 46 consecutive patients with clinically suspected PNS who underwent 18 F-FDG-PET/CT were reviewed retrospectively and the performance of PET/CT for detecting underlying tumours was assessed. PET/CT detected foci of increased 18 F-FDG uptake in 10 out of 46 patients. In six of these 10 patients combined PET/CT identified the underlying disease: four patients suffered from PNS; vasculitic and local metastatic disease was detected in two other patients. Based on our results, we believe that the role of positron emission tomography in the detection of occult neoplasms in patients with PNS has been overestimated in the past. In clinical practice, PNS is far more often suspected than proven. In our study combined PET/CT identified malignancy as the underlying cause of suspected PNS in only 8.7% (4/46). We believe that combined PET/CT should be reserved for stringently selected patients with a high clinical index of suspicion for PNS and after conventional imaging techniques fail to detect a tumour.

    Objective: To evaluate the clinical characteristics and etiologies of central diabetes insipidus (CDI). Methods: The clinical data of 230 patients with CDI in the Department of Endocrinology of Chinese PLA General Hospital from 2008 June to 2014 December were collected and analyzed retrospectively. Results: The three most common causes of CDI were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. Among all the CDI, the idiopathic CDI accounted for 37.48%. There were significant differences in age onset and gender distribution among the different causes of CDI. The patients with intracranial germ cell tumors [age of onset(19.2±10.2) years] were younger than the other types of CDI. Germ cell tumors patients were more common in male, and lymphocytic hypophysitis patients were more common in female. The most frequent abnormality of anterior pituitary in patients with CDI was growth hormone deficiency, followed by hypogonadism, adrenal insufficiency and hypothyroidism. The dysfunction of thyroid axis and adrenal axis in patients with germ cell tumor was more common than those in patients with idiopathic and lymphocytic hypophysitis. Conclusions: The most common causes of central diabetes insipidus were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. There were differences in age of onset, gender distribution and abnormal production of anterior pituitary hormones among all causes of CDI patients.

    The autopsy material of the institutes for forensic medicine in Berlin/GDR and Hamburg was analyzed retrospectively (period from 1961 till 1987; 70,000 autopsies) for fatalities caused by "humane killers" (n = 22) and stud guns (n = 12).-Epidemiological, criminological and morphological findings: The decreased were all men aged between 18 and 75 years (mean 48 years) except one 61 year-old paraplegic women who was killed by her husband with a humane killer. The great majority of cases consisted of suicides; two accidents at work were caused by stud guns. These unusual weapons are normally used by skilled people (i.e. butchers or constructional workers respectively). The fatal wounds were situated at the head, especially the forehead, seldom at the nape of the neck or in the mouth, or sometimes in the chest when using stud guns. Combined suicides (especially together with hanging) are not unusual. Survival periods (with or without acting capacity) can range between minutes or even months (after neurosurgical intervention).-The frequency of such unusual and overall rare cases did not raise during the investigation period.

    Psychiatric concerns are a common presenting problem for pediatric providers across many settings, particularly on inpatient medical services. The volume of youth requiring intensive psychiatric treatment outnumbers the availability of psychiatric placements, and as a result many youth must board on pediatric medical units while awaiting placement. As the phenomenon of boarding in the inpatient pediatric setting increases, it is important to understand trends in boarding volume and characteristics of pediatric psychiatric boarders (PBs) and understand the supports they receive while boarding. A retrospective chart review of patients admitted as PBs to a medical inpatient unit at a large northeastern US pediatric hospital during 2013. Four hundred thirty-seven PBs were admitted to the medical service from January to December 2013, representing a more than 50% increase from PB admissions in 2011 and 2012. Most PBs were admitted for suicidal attempt and/or ideation. Average length of boarding was 3.11 ± 3.34 days. PBs received a wide range of mental health supports throughout their admissions. PBs demonstrated modest but statistically significant clinical improvements over the course of their stay, with only a small proportion demonstrating clinical deterioration. Psychiatric boarding presents many challenges for families, providers, and the health care system, and PBs have complex psychiatric histories and needs. However, boarding may offer a valuable opportunity for psychiatric intervention and stabilization among psychiatrically vulnerable youth. Copyright © 2017 by the American Academy of Pediatrics.

    Purpose: This was a retrospective observational study to elicit the outcome of the therapeutic strategy of concurrent neoadjuvant chemoradiotherapy protocol for locally advanced breast cancer. Methods and Materials: A large series of 1,117 consecutive cases of locally advanced breast cancer treated at the Cancer Institute (WIA), in Chennai, South India, between 1990 and 1999 and followed through 2004 formed the basis for this study. Disease-free survival was the main outcome, and nodal and tumor downstaging were the intermediate outcome measures studied. Results: Primary tumor downstaging was observed in 45% and nodal downstaging in 57.5%. The disease-free survival rate of nodal downstaged patients at 5, 10, and 15 years was 75%, 65%, and 58%, respectively. The corresponding rates for pre- and postoperative node-negative patients were 70%, 60%, and 59%. The best survival was seen among those who were tumor and node negative postoperatively. Nodal downstaging halved the risk of disease recurrence and death compared with node positivity, irrespective of tumor sterility. Conclusions: A randomized trial using cyclophosphamide, methotrexate, and 5-fluorouracil vs. an anthracycline-based regimen in the setting of concurrent chemoradiotherapy appears indicated. Additional preoperative chemotherapy to maximize nodal and tumor downstaging should be investigated. A change in postoperative chemotherapy according to nodal status could also be explored

    The aim of this retrospective study was to evaluate the stability of spinal metastases in gynecologic cancer patients (pts) on the basis of a validated scoring system after radiotherapy (RT), to define prognostic factors for stability and to calculate survival. Fourty-four women with gynecologic malignancies and spinal bone metastases were treated at our department between January 2000 and January 2012. Out of those 34 were assessed regarding stability using the Taneichi score before, 3 and 6 months after RT. Additionally prognostic factors for stability, overall survival, and bone survival (time between first day of RT of bone metastases and death from any cause) were calculated. Before RT 47% of pts were unstable and 6 months after RT 85% of pts were stable. Karnofsky performance status (KPS) >70% (p = 0.037) and no chemotherapy (ChT) (p = 0.046) prior to RT were significantly predictive for response. 5-year overall survival was 69% and 1-year bone survival was 73%. RT is capable of improving stability of osteolytic spinal metastases from gynecologic cancer by facilitating re-ossification in survivors. KPS may be a predictor for response. Pts who received ChT prior to RT may require additional bone supportive treatment to overcome bone remodeling imbalance. Survival in women with bone metastases from gynecologic cancer remains poor

    Evaluation of the treatment, epidemiology and outcome of cardiac arrest in the television franchise Star Trek. Retrospective cohort study of prospective events. Screening of all episodes of Star Trek: The Next Generation, Star Trek: Deep Space Nine and Star Trek: Voyager for cardiac arrest events. Documentation was performed according to the Utstein guidelines for cardiac arrest documentation. All adult, single person cardiac arrests were included. Patients were excluded if cardiac arrest occurred during mass casualties, if the victims were annihilated by energy weapons or were murdered and nobody besides the assassin could provide first aid. Epidemiological data, treatment and outcome of cardiac arrest victims in the 24th century were studied. Ninety-six cardiac arrests were included. Twenty-three individuals were female (24%). Cardiac arrest was witnessed in 91 cases (95%), trauma was the leading cause (n = 38; 40%). Resuscitation was initiated in 17 cases (18%) and 12 patients (13%) had return of spontaneous circulation. Favorable neurological outcome and long-term survival was documented in nine patients (9%). Technically diagnosed cardiac arrest was associated with higher rates of favorable neurological outcome and long-term survival. Neurological outcome and survival did not depend on cardiac arrest location. Cardiac arrest remains a critical event in the 24th century. We observed a change of etiology from cardiac toward traumatic origin. Quick access to medical help and new prognostic tools were established to treat cardiac arrest.

    Full Text Available The geographic distribution of paracoccidioidomycosis (PCM in the Brazilian state of São Paulo was evaluated in a retrospective study using secondary data from serological analyses, carried out by double immunodiffusion assay of patients with PCM suspicion, from January 1999 to May 2010. Sixty percent of 10,176 patients, from 239 cities, were serologically reactive to P. brasiliensis. The cities that showed the most serological reactivity among patients were São João da Boa Vista (85%, Piracicaba (75%, Sorocaba (73%, Campinas (72% and São Paulo (62%. São Paulo state has an area of 248,209.4 km²; the climate is tropical and sub-tropical with annual temperatures between 18 and 24ºC, high rainfall (900 to 1800 mm/year, rainy summers and mild winters. It also features large areas composed of acidic soils, and is one of the greatest contributors to Brazilian agricultural production and, separately, the largest producer of orange juice and, the ninth greatest producer of soy and sugar cane and the fourth largest coffee producer. We suggest that the climatic characteristics associated with soil type and development of primary activities can contribute to the endemic potential of PCM in São Paulo state.

    The purpose of this study was to retrospectively evaluate the results from a Helical TomoTherapy Hi-Art treatment system relating to quality controls based on daily static and dynamic output checks using statistical process control methods. Individual value X-charts, exponentially weighted moving average charts, and process capability and acceptability indices were used to monitor the treatment system performance. Daily output values measured from January 2014 to January 2015 were considered. The results obtained showed that, although the process was in control, there was an out-of-control situation in the principal maintenance intervention for the treatment system. In particular, process capability indices showed a decreasing percentage of points in control which was, however, acceptable according to AAPM TG148 guidelines. Our findings underline the importance of restricting the acceptable range of daily output checks and suggest a future line of investigation for a detailed process control of daily output checks for the Helical TomoTherapy Hi-Art treatment system.

    Despite iron supplementation, some preterm infants develop iron deficiency (ID). The optimal iron status parameter for early detection of ID has yet to be determined. To establish reference ranges for reticulocyte haemoglobin content (Ret-He) in preterm and term infants and to identify confounding factors. Retrospective analyses of Ret-He and complete blood count in infants with a clinically indicated blood sample obtained within 24 h after birth. Mean (SD) Ret-He was 30.7 (3.0) pg in very preterm infants with a gestational age (GA) of pH (r = -0.07). There was a slight variation in Ret-He with mode of delivery [normal vaginal delivery: 32.3 (3.2) pg, secondary caesarean section (CS): 31.4 (3.0) pg, instrumental delivery: 31.3 (2.7) pg and elective CS: 31.2 (2.8) pg]. GA at birth has a negligible impact on Ret-He, and the lower limit of the normal reference range in newborns within 24 h after birth can be set to 25 pg. Moreover, Ret-He seems to be a robust parameter which is not influenced by perinatal factors within the first 24 h after birth. © 2016 S. Karger AG, Basel.

    Objective: To investigate the causes of failure in treating atrial septal defect (ASD) and ventricular septal defect (VSD) with interventional procedures and to evaluate the clinical efficacy of surgical treatment in order to increase the successful rate. Methods: A total of 13 patients, who underwent surgical therapy because of unsuccessful interventional treatment for ASD or VSD during the period of January 2001-December 2007, were selected,and the clinical data were retrospectively analyzed. The surgical indications included the occluder abscission (n=7), III degree atrioventricular conduction block (n=3), valvular regurgitation (n=2), residual shunt (n=1) and interventional failure (n=1). The cardiac surgeries, including removal of the displaced occluder and / or the repair of atrioventricular septal defects, were performed with the help of cardiopulmonary bypass in all 13 cases. After surgical treatment, all patients were transferred into ICU for further supervision and treatment. Results: The average diameter of ASD on surgical exploration was 31 mm, which was greater than the preoperative average diameter (26 mm), with a significant difference (P 0.05). The III degree atrioventricular conduction block in 3 cases restored sinus rhythm after operation. All the procedures were successfully completed in all patients. No death occurred during the hospitalization period. Conclusion: Proper and timely cardiac surgery is an effective and safe measure for the treatment of the complications due to unsuccessful interventional therapy as well as the atrioventricular septal defect itself.

    The high cost of intrathecal morphine pump (ITMP) implantation may be the main obstacle to its use. Since July 2014, the Korean national health insurance (NHI) program began paying 50% of the ITMP implantation cost in select refractory chronic pain patients. The aims of this study were to investigate the financial break-even point and patients' satisfaction in patients with ITMP treatment after the initiation of the NHI reimbursement. We collected data retrospectively or via direct phone calls to patients who underwent ITMP implantation at a single university-based tertiary hospital between July 2014 and May 2016. Pain severity, changes in the morphine equivalent daily dosage (MEDD), any adverse events, and patients' satisfaction were determined. We calculated the financial break-even point of ITMP implantation via investigating the patient's actual medical costs and insurance information. During the studied period, 23 patients received ITMP implantation, and 20 patients were included in our study. Scores on an 11-point numeric rating scale (NRS) for pain were significantly reduced compared to the baseline value ( P break-even point was 28 months for ITMP treatment after the NHI reimbursement policy. ITMP provided effective chronic pain management with improved satisfaction and reasonable financial break-even point of 28 months with 50% financial coverage by NHI program.

    To determine the efficacy of hybrid external fixation in the treatment of tibial pilon fractures. Retrospective, multicentre study. Adult patients with tibial pilon fractures treated with hybrid external fixation. Fracture reduction with ligamentotaxis and fixation with XCaliber hybrid external fixator. Fracture union, complications, functional outcome (Mazur Ankle Score). Union was obtained in 159 fractures at an average of 125days; there were three delayed unions and three non-unions. The most frequent complication was superficial pin-track infections (48), all of which responded to local wound care and antibiotics. There were no deep infections and no DVT. Only one fracture had loss of reduction that required frame revision. The overall functional scores were 91 (excellent) for AO/OTA type A fractures, 89 (good) for type B fractures, and 75 (satisfactory) for type C fractures. Hybrid external fixation is an effective method of stabilising tibial pilon fractures, particularly those with marked comminution. The minimally-invasive technique and stable fixation enable early mobilisation, with good functional results and minimal complications. Level IV Case series. Copyright © 2016 Elsevier Ltd.

    Resistant hypertension is still a challenge and reserve antihypertensive agents are often necessary to achieve blood pressure control. One reserve antihypertensive is minoxidil, a direct vasodilator that is known for its strong blood pressure-lowering effect, but contemporary studies are sparse. The authors retrospectively analyzed 54 inpatients with uncontrolled hypertension despite the combined use of current antihypertensive agents. To investigate the effect of minoxidil when added to other antihypertensive agents, blood pressure was evaluated at the time minoxidil treatment was initiated and at discharge. Minoxidil treatment was associated with a significant reduction in blood pressure from 162.4±15.1/83.2±12.7 mm Hg to 135.8±12.2/72.8±6.9 mm Hg (Pminoxidil limit its widespread use, these data show that minoxidil as a reserve antihypertensive agent still has a niche indication in the particular subgroup of patients with treatment-resistant or uncontrolled hypertension. ©2016 Wiley Periodicals, Inc.

    There is inconclusive evidence on the value of regular dental attendance. This study explored the relationship between long-term patterns of dental attendance and caries experience. We used retrospective data from 3,235 adults, ≥ 16 yrs of age, who participated in the Adult Dental Health Survey in the UK. Participants were classified into four groups (always, current, former, and never regular-attenders) based on their responses to three questions on lifetime dental-attendance patterns. The association between dental-attendance patterns and caries experience, as measured using the decayed, missing, or filled teeth (DMFT) index, was tested in negative binomial regression models, adjusting for demographic (sex, age, and country of residence) and socio-economic (educational attainment, household income, and social class) factors. A consistent pattern of association between long-term dental attendance and caries experience was found in adjusted models. Former and never regular-attenders had a significantly higher DMFT score and numbers of decayed and missing teeth, but fewer filled teeth, than always regular-attenders. No differences in DMFT or its components were found between current and always regular-attenders. The findings of this study show that adults with different lifetime trajectories of dental attendance had different dental statuses. © 2014 Eur J Oral Sci.

    Background: Seborrheic keratosis is a common, benign skin tumor. Numerous reports have shown its possibility of malignant transformation. This study was designed to demonstrate the occurrence of concomitant seborrheic keratosis and skin cancers. Materials and Methods: Data was retrospectively reviewed from all patients with a diagnosis of seborrheic keratosis in pathology department of Alzahra Hospital and a private pathology laboratory in Isfahan, Iran over a 4-year period. We classified all demographic data and associated dysplasia or Bowen's disease and analyzed them by student-t or chi-square tests. Results: From all 429 specimens, 5 (1.2%) were found to be associated with Bowen's disease and one (0.2%) with mild dysplasia in squamous epithelium. All cases arose within the clinically, atypical seborrheic keratosis. More men were affected with lesions alone and with malignancy (230/423 (54.4%) and 5/6 (83.3%), respectively) compared to women. The average age of patients suffering from lesions with and without associated malignancy was 57 and 54 years, respectively. The common site of lesion alone was head and neck but lesions with malignancy involved lower extremities. The two lesions were significantly different in site of occurrence (p keratosis and skin malignancy appears to be accidental, it must always be in mind. Therefore, histopathologic examination of all seborrheic keratosis should be considered, especially when seborrheic keratosis has atypical clinical manifestations. PMID:23267371

    To cost the relation between socioeconomic status and various measures of primary care workload and assess the adequacy of current "deprivation" payments in relation to actual costings for patients living in qualifying areas. Retrospective data on primary care were collected over a 4.5 year period from both computerised and manually filed records. Standardised data on socioeconomic status were obtained by postal questionnaire. Inner city group practice with a socioeconomically diverse population. 382 male and female subjects of all ages, with a total of 1296 person years of observation. Primary care costs resulting from consultations with a general practitioner or a practice nurse and both new and repeat prescriptions. Morbidity, workload, and costs of drug treatment increased with decreasing socioeconomic status. The difference in cost for patients in social classes IV and V combined compared with those in I and II combined was about 150 Pounds per person year at risk (47 Pounds for workload and 103 Pounds for drugs). Deprivation payments met only half the extra workload cost for patients from qualifying wards. The greater workload caused by social disadvantage has been previously underestimated by simple consultation rates. The absolute difference in costs for socially disadvantaged patients increase as more detailed measures of workload and drug treatment are included. Current deprivation payments only partially offset the increased expenditure on workload. This shortfall will have to be addressed to attract general practitioners to, or retain them in, deprived areas.

    The purpose of this study was to evaluate the application of sonography at the polyclinic of the Olympic/Paralympic village during the Olympic/Paralympic Games. We retrospectively reviewed 759 consecutive patients who underwent sonography at the ultrasound division of the polyclinic in the Olympic/Paralympic village from July 20, 2008, to September 20, 2008. Prevalence of emergency sonography after sports injury and non-sports-related urgent conditions during the games was analyzed. The benefit of sonographic services in large sporting events was discussed. There were 759 patients (484 athletes, 101 coaches, 88 team officials, and 86 volunteers; 462 men and 297 women) in the ultrasound division at the polyclinic. The indications for sonography included abdominal pain (315 cases, 41.50%), muskuloskeletal disorders (228 cases, 30.04%), gynecology related (104 cases, 13.70%), cardiac conditions (49 cases, 6.46%), small parts (29 cases, 3.82%), and vascular problems (34 cases, 4.48%). The rates of positive findings on sonography were 46.03% in the abdomen, 70.17% in musculoskeleton, 41.34% in gynecology, 10.20% in the heart, 75.86% in small parts, and 38.24% in vessels, respectively. Sonography plays an important role in the medical services at the polyclinic in the Olympic/Paralympic village. The benefits of sonography in such large sporting events are accuracy, fast result, portability, and noninvasiveness. Copyright © 2011 Elsevier Inc. All rights reserved.

    Several factors may influence aesthetic outcomes of ptosis surgery, especially in patients with asymmetrical ptosis. We retrospectively assessed the effect of Hering's law on surgical outcomes of patients with asymmetrical ptosis. Patients with mild to moderate asymmetrical ptosis (N = 300) who underwent advancement or plication of upper eyelid aponeurosis between January 2014 and July 2016 were enrolled. Fifty patients (group A) underwent surgery without taking into consideration the impact of Hering's law. Of these, 35 patients with unilateral ptosis (subgroup A1) underwent standard surgery on the contralateral side, whereas 15 patients with bilateral ptosis (subgroup A2) were first operated on the milder side followed by the more severely affected side.In 250 patients (group B), surgery was performed taking cognizance of the implications of Hering's law. These included 100 patients with unilateral ptosis (B1) and 150 with bilateral ptosis (B2). Difference in bilateral palpebral fissure symmetry by less than 0.5 mm was considered as satisfactory outcome. Duration of postoperative follow-up ranged from 3 to 24 months. Satisfactory outcomes were achieved over 60% of patients in group A (A1, 60.6%; A2, 66.67%) and in 96% of patients in group B (B1, 95%; B2, 96.67%). Patients with unsatisfactory outcomes underwent repair according to Hering's law after 3 months and obtained good results. Application of Hering's law may improve outcomes of corrective surgery in patients with asymmetric ptosis.

    To compare the institutional cost of permanent female sterilization by Essure hysteroscopic sterilization and laparoscopic bilateral coagulation. Retrospective cohort study (Canadian Task Force classification II-2). Midwestern academic medical center. Women of reproductive age who elected for permanent contraception by the Essure method (n = 43) or by laparoscopic tubal coagulation (n = 44) during the time frame studied. Placement of the Essure inserts according to the manufacturer's instructions or laparoscopic tubal sterilization using bipolar forceps according to standard techniques of open or closed laparoscopy. Cost-center data for the institutional cost of the procedure was abstracted for each patient included in the study. In addition, demographic data and procedural information were obtained and compared for the patient populations. The Essure system of hysteroscopic sterilization had a significantly decreased cost compared with laparoscopic tubal sterilization when both procedures were performed in an operating room setting. The decrease per patient in institutional cost was 180 dollars (p = .038). This included the cost of the confirmatory hysterosalpingogram 3 months after Essure placement and the cost of laparoscopic tubal occlusion by Filshie clip if the Essure micro-inserts could not be placed. The majority of the cost was related to hospital costs as opposed to physician costs. The Essure procedure had higher costs for disposable equipment (p Essure hysteroscopic sterilization had significant cost savings compared with laparoscopic tubal sterilization (p = .038). We believe that our data represent the minimum of potential savings using this approach, and future developments will only increase the cost difference found in our study.

    To assess the management and maternal outcomes of placenta accreta spectrum (PAS) disorders. A retrospective chart review was conducted of patients diagnosed with PAS disorders (placenta creta, increta, or percreta) who were treated at a US tertiary care center between February 1, 2011, and January 31, 2016. Obstetric management, anesthetic management, and maternal outcomes were analyzed. A total of 43 cases were identified; placenta previa was diagnosed among 33 (77%). Median age was 33 years (range 23-42). Median blood loss was 1500 mL (interquartile range 1000-2500); blood loss was greatest among the 10 patients with placenta percreta (3250 mL, interquartile range 2200-6000). Transfusion of blood products was necessary among 14 (33%) patients, with no difference in frequency according to the degree of placental invasion (P=0.107). Surgical complications occurred among 10 (23%) patients. Overall, 30 (70%) patients received combined spinal-epidural plus general anesthesia, 4 (9%) received only general anesthesia, and 9 (21%) underwent surgery with combined spinal-epidural anesthesia. One patient experienced difficult airway and another experienced accidental dural puncture. Placenta previa and accreta coexist in many patients, leading to substantial bleeding related to the degree of myometrial invasion. An interdisciplinary team approach plus the use of combined spinal-epidural anesthesia, transitioning to general anesthesia, were advisable and safe. © 2017 International Federation of Gynecology and Obstetrics.

    Psychotimulant-antipyschotic combinations are frequently used in child psychiatry, but have been rarely described in the literature. We propose here a retrospective study of 44 children who received the combination methylphenidate (MPH)-risperidone (RIS). The sample is composed of children who received either MPH (n=28) or RIS (n=16) as primary treatment. A vast majority of the children had a comorbid attention deficit hyperactivity disorder (ADHD) diagnosis. For over 60% of patients, regardless of their initial monotherapy, bitherapy decreased the symptoms of ADHD and conduct disorder, sleep disorders and anxiety. Concerning the safety of the bitherapy, a compensation effect on weight gain and appetite was respectively observed in 70% and 50% of patients. Even though iatrogenic tachycardia can be encountered with both drugs, it has never been reported when they are associated and we have reported a total of 3 cases in our study. We have also observed a case of dyskinesia resolved with the discontinuation of the treatment. MPH-RIS bitherapy appears to be particularly effective in ADHD with conduct disorder symptoms. Although tolerance may limit its use, the benefit/risk ratio seems favourable for a number of children. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    To determine the net financial gain or loss for medication therapy management (MTM) services provided to patients by an independent community pharmacy during 16 months of operation. Retrospective study. Independent community pharmacy in Iowa City, IA, from September 1, 2006, to December 31, 2007. Patients receiving MTM services during the specified period who had proper documentation of reimbursement for the services. MTM services were provided to the patient and documented by the pharmacist or student pharmacist. Net financial gains or losses for providing MTM services. Sensitivity analyses included costs that might be incurred under various conditions of operation. 103 initial and 88 follow-up MTM visits were conducted during a 16-month time period. The total cost for these services to the pharmacy was $11,191.72. Total revenue from these services was $11,195.00; therefore, the pharmacy experienced a net financial gain of $3.28. Sensitivity analyses were conducted, revealing the net gain/loss to the pharmacy if a student pharmacist was used and the net gain/loss if the pharmacist needed extra training to provide the services. Using a student pharmacist resulted in a net gain of $6,308.48, while extra training for the pharmacist resulted in a net loss of $1,602.72. The MTM service programs showed a positive financial gain after 16 months of operation, which should encourage pharmacists to incorporate these services into their practice.

    We aimed to describe the longitudinal changes in bone mineral content and influencing factors, in children with cystic fibrosis (CF). One hundred children (50 females) had dual X-ray absorptiometry (DXA) performed. Of these, 48 and 24 children had two to three scans, respectively over 10 years of follow-up. DXA data were expressed as lumbar spine bone mineral content standard deviation score (LSBMCSDS) adjusted for age, gender, ethnicity and bone area. Markers of disease, anthropometry and bone biochemistry were collected retrospectively. Baseline LSBMCSDS was >0.5 SDS in 13% children, between -0.5; 0.5 SDS, in 50% and ≤-0.5 in the remainder. Seventy-eight percent of the children who had baseline LSBMCSDS >-0.5, and 35% of the children with poor baseline (LSBMCSDS0.5), showed decreasing values in subsequent assessments. However, mean LS BMC SDS did not show a significant decline in subsequent assessments (-0.51; -0.64; -0.56; p=0.178). Lower forced expiratory volume in 1 s percent (FEV1%) low body mass index standard deviation scores (BMI SDS) and vitamin D were associated with reduction in BMC. Bone mineral content as assessed by DXA is sub-optimal and decreases with time in most children with CF and this study has highlighted parameters that can be addressed to improve bone health.

    Objective. Between one-third and half of all radiology examinations worldwide are probably chest studies. The aim of the current study was to retrospectively evaluate the clinical influence of chest radiography. Methods. In a tertiary referral hospital, 939 consecutive daytime chest radiography examinations were evaluated. The outcome was classified as normal, incidental, or pathologic. The referring physicians reaction to radiologic outcome was classified as highly expected, moderately expected, or unexpected. The influence on the patients' treatment was divided into four groups from major to no influence. Results. In all, 71.6% of the studies had a highly expected outcome. Moderately expected or unexpected outcomes were noted in 36.6% of 500 pathologic examinations. Unexpected outcome was noted in 11.6% of all studies. The radiologic outcome influenced treatment in 65.4% of patients where pathology was demonstrated. Patients with normal or incidental findings had treatment influenced in 1/3 of the cases. Unexpected findings influenced treatment more than moderately expected findings. When radiological findings were highly expected, treatment was influenced in less than half of the cases. Surprisingly few chest radiology examinations were commented upon in the medical records

    Objective: The counterclockwise rotation of the SMV on SMA is a normal and non-specific finding, which results in an incomplete swirl formation on CT scans. However, it has a potential to be misinterpreted as ‘midgut volvulus’ resulting in serious clinical implications. The study was done to determine the frequency and degree of counterclockwise rotation of the SMV on SMA on CT in normal otherwise asymptomatic pediatric patients undergoing CT scan. Methods: In this IRB approved study, we retrospectively analyzed abdominal CT scan examinations of 200 consecutive pediatric patients (age range of 11 days to 18 years), which were performed for different clinical indications over a period of 10 months. They were evaluated for the absence or presence and degree of counterclockwise rotation of the mesenteric vessels. Results: Of the 200 patients, 128 (64%) patients showed no clockwise or anticlockwise rotation of mesenteric vessels. Counterclockwise rotation of SMV on SMA was seen in 72 (36%) patients. Further, the degree of rotation of vessels was also calculated, based on the criteria proposed by the authors. Conclusions: The counterclockwise rotation of SMV on SMA gives an appearance of mesenteric whirlpool in otherwise normal mesenteric vessels and can be misinterpreted as midgut volvulus. It is a normal CT appearance and is due to a variation in branching pattern of mesenteric vessels. Awareness of this normal branching pattern of mesenteric vessels is important to avoid an inadvertent laparotomy.

    Objective: The counterclockwise rotation of the SMV on SMA is a normal and non-specific finding, which results in an incomplete swirl formation on CT scans. However, it has a potential to be misinterpreted as ‘midgut volvulus’ resulting in serious clinical implications. The study was done to determine the frequency and degree of counterclockwise rotation of the SMV on SMA on CT in normal otherwise asymptomatic pediatric patients undergoing CT scan. Methods: In this IRB approved study, we retrospectively analyzed abdominal CT scan examinations of 200 consecutive pediatric patients (age range of 11 days to 18 years), which were performed for different clinical indications over a period of 10 months. They were evaluated for the absence or presence and degree of counterclockwise rotation of the mesenteric vessels. Results: Of the 200 patients, 128 (64%) patients showed no clockwise or anticlockwise rotation of mesenteric vessels. Counterclockwise rotation of SMV on SMA was seen in 72 (36%) patients. Further, the degree of rotation of vessels was also calculated, based on the criteria proposed by the authors. Conclusions: The counterclockwise rotation of SMV on SMA gives an appearance of mesenteric whirlpool in otherwise normal mesenteric vessels and can be misinterpreted as midgut volvulus. It is a normal CT appearance and is due to a variation in branching pattern of mesenteric vessels.

    Computed tomography of the kidneys, ureters and bladder is the recommended imaging modality for suspected urolithiasis. Early scanning is advised in guidelines, but there is limited published evidence to support this recommendation. In a retrospective study, we reviewed patients managed according to a local guideline. Patients without high-risk features were either imaged during their initial visit (if in the daytime) or discharged for outpatient scans. Complications, unplanned returns, final diagnosis, and intervention rates were compared between groups. Fifty-four patients were scanned during their initial visit and 151 were scanned as an outpatient at a median interval of 10 days. Unplanned return rates were lower in those scanned as outpatients (7.3 vs. 24.1%), with no significant difference in complications (2.0 vs. 3.7%; none leading to permanent harm). Those scanned as outpatients were less likely to have a stone proven by imaging (39.7 vs. 64.8%), but did not have a significantly higher rate of proven alternative diagnosis (9.3 vs. 13.0%). There is no evidence in this cohort that discharging patients for outpatient imaging is associated with poorer outcomes, provided that an appropriate clinical risk assessment is carried out.

    Full Text Available Aim: This study aimed to analyze blunt chest trauma cases who were diagnosed with rib fracture and to examine the regional differences likely to appear in trauma cases and treatment approaches. Material and Method: 513 cases who applied to the Emergency Service and Department of Thoracic Surgery between October 2013 and December 2014 due to blunt trauma and were diagnosed with rib fracture were retrospectively examined. The cases were evaluated in terms of etiological factors, thoracic, and other system injuries accompanying the rib fracture, prognosis, and the treatments applied. Results: Isolated rib fracture was present in 266 of the cases. Thoracic organ injuries such as pneumothorax, hemothorax, hemopneumothorax, lung contusion, or laceration and sternal fracture accompanying the rib fracture were present in 247 of the cases. While one or two rib fractures were detected in 298 cases, six or more rib fractures were present in 28 cases. 78.2% of hemothorax cases, 85.3% of pneumothorax cases, 95.4% of hemopneumothorax cases, 81.8% of bilateral pneumothorax cases, 26% of bilateral hemothorax cases, and 71.4% of bilateral hemopneumothorax cases were treated by applying tube thoracostomy. 129 cases diagnosed with thoracic organ injury in addition to rib fracture but not subjected to surgical intervention, and 266 cases diagnosed with isolated rib fracture were discharged with full recovery after appropriate medical treatment. Discussion: Most of the rib fractures occurring due to blunt trauma are treated successfully with medical treatments and conservative approaches and do not need advanced surgical treatments.

    This study was undertaken to determine if ALS patients evaluated via telemedicine received the same quality of care as patients evaluated by traditional face-to-face encounters. A retrospective cohort study design was used. Participants were patients diagnosed with ALS that received multidisciplinary care at the tertiary Cleveland VA ALS Centre between 1 March 2008- and 31 anuary 2015. Participants were not randomised, but chose telemedicine based on preference, disability level or distance from the clinic. Telemedicine in this study consisted of a video conferencing platform enabling remote rather than face-to-face encounters with participants. There was no significant association between receiving quality ALS care and the mode of care. There was a trend for telemedicine patients to utilise home health care less often than those that received clinic care (AOR 0.50; 95% CI 0.16-1.59). There was no significant difference in survival time between the two groups (log-rank test χ 2  = 3.62, df = 1, p = 0.05). Patients receiving telemedicine had a higher probability of remaining stable or having telemedicine (HR = 0.39, 95% CI = 0.16-0.93). Patients managed by telemedicine received the same quality of care and had similar outcomes to those patients seen via traditional face-to-face encounters. Telemedicine is an effective platform for delivering high quality tertiary ALS care.

    Women present later than men for total knee arthroplasty (TKA) with more severe osteoarthritic disease but achieve comparable functional improvement and implant survival and also lower rates of revision. Despite these findings, there is significant underutilization of the procedure for women compared to men. We conducted a retrospective study to address the lack of information in the literature concerning the immediate and short-term perioperative outcomes between genders. The National Hospital Discharge Survey was evaluated between 2001 and 2010 for men and women undergoing primary TKA in the United States. Differences in gender, patient demographics, comorbidities, complications, length of stay, and discharge disposition were analyzed and identified. The growth in TKA was 145% for men and 131% for women over the 10-year period. Women presented with significantly higher rates of obesity, morbid obesity, postoperative transfusion rate, and length of stay. In contrast, men showed a greater proportion of diabetes, postoperative wound infections, and increased mortality rates. Males were also more likely to be discharged to home, whereas females were more likely to be discharged to rehabilitation facilities. Our findings provide important insight into the perioperative outcomes that may be influencing gender disparity in TKA. Copyright © 2016 Elsevier Inc. All rights reserved.

    The prescription of opioids for the treatment of chronic non-cancer pain (CNCP) is not recommended for all of them, and can expose the patients to a benefit/risk ratio unfavorable. The objective of this study was to evaluate the management of patients hospitalized at the centre for evaluation and treatment of pain for opioid withdrawal, their outcome during hospitalization. This is a retrospective descriptive study. The medical record of each patient was consulted to identify relevant data (demographics, treatments at the entrance and discharge of hospitalization, comorbidities, rating scale of pain). During the study period (3 years), 53 patients (64% of women), with a median age of 52 years, were included. Pain was mainly back pain and neck pain (52%). Morphine (43%) and fentanyl (42%) were the most frequently used opioids. At admission, 62% of patients had a depressive state. At hospital discharge, withdrawal was total in 18 patients (34%) and a total improvement of pain was observed for 19% of them. In this study, 57% of patients received, at admission to hospital, an opioid other than morphine in the treatment of CNCP. The management of pain offered by the pain clinic led to a total or partial opioid withdrawal in 94% of patients. © 2013 Société Française de Pharmacologie et de Thérapeutique.

    To evaluate whole-body magnetic resonance imaging (WB-MRI) for the assessment of bone marrow infiltration in patients with confirmed Gaucher disease type 1 under long-term enzyme replacement therapy (ERT). This retrospective data analysis included 38 patients in two subgroups. Group A: 10 females, 9 males, 15-29 years, mean age 22 years and Group B: 11 females, 8 males, 29-77 years, mean age 49 years, all treated with alglucerase or imiglucerase for at least 12.5 years. Whole-body MRI was carried out in all patients using a standard MRI protocol. Two radiologists assessed all MR images retrospectively with the use of three different MRI score systems: The bone marrow burden (BMB) score, the Düsseldorf-Gaucher score (DGS) and the vertebra disc ratio (VDR). As a clinical component, severity score index type 1 (GD-DS3) was determined. In both groups the MR scores showed low to moderate pathologic levels but no statistically significant difference was found between both groups. The median scores in group A/group B were 7.00/9.00 for the BMB score (p=0.07), 4.00/3.00 for the DGS score (p=0.062) and 1.54/1.62 for the VDR score (p=0.267). The GD-DS3 score was statistically significantly different between both groups (1.6/3.9, p=0.000) and osseous Gaucher disease complications were only found in group B. Bone marrow involvement and typical clinical manifestations are reduced to a minimum, when ERT starts immediately after the confirmed diagnosis of Gaucher disease type 1. The applied MR scores are useful markers to control bone marrow infiltration under enzyme replacement therapy in older patients. Pathologic MR scores in young patients may reflect postponed fat conversion of the juvenile bone marrow. This issue has to be examined in further studies. Whole-body MRI is valuable for the staging of Gaucher disease type 1. Osseous complications are reduced to a minimum in early treated patients. MR score systems have to be adjusted in young Gaucher patients. © Georg Thieme

    Numerous studies have reported the prevention of falls through exercise among cognitively healthy older people. This study aimed to determine whether the current evidence supports that physical exercise is also efficacious in preventing falls in older adults with cognitive impairment. Two independent reviewers searched MEDLINE; EMBASE; PsycINFO; the Cumulative Index to Nursing & Allied Health Literature; the Cochrane Central Register of Controlled Trials; the Cochrane Bone, Joint, and Muscle Trauma Group Specialized Register; ClinicalTrials.gov; and the UK Clinical Research Network Study Portfolio up to July 2013 without language restriction. We included randomized controlled trials that examined the efficacy of physical exercise in older adults with cognitive impairment. The methodological qualities of the included trials were appraised according to the criteria developed for the Cochrane review of fall prevention trials. The primary outcome measure was the rate ratio of falls. A meta-analysis was performed to estimate the pooled rate ratio and summarize the results of the trials on fall prevention through physical exercise. Seven randomized controlled trials involving 781 participants were included, 4 of which examined solely older people with cognitive impairment. Subgroup data on persons with cognitive impairment were obtained from the other 3 trials that targeted older populations in general. The meta-
