    Full Text Available Adolescent idiopathic scoliosis is a spinal deformity that affects patients’ self image and confidence. Surgery is offered when the curvature is greater than 50 degrees based on the likelihood of curvature progression. Outcome measures for scoliosis correction can be described in terms of radiological improvement or improvement of health related quality of life scores. The Scoliosis Research Society 22 (SRS-22 and Scoliosis Research Society 24 (SRS-24 questionnaires are widely accepted and used to characterize clinical results. Therefore, this prospective study of 38 patients aims to investigate how the SRS-24 and SRS-22 questionnaires compare to each other in terms of scoring when the same group of patients is evaluated. The SRS-22 questionnaire tends to give an inflated value in the overall score, pain and self image domain compared to the SRS-24 questionnaire.

    Feed coals and fly ashes from a coal-fired power station burning Alberta subbituminous coal were examined for a period of thirty-eight weeks to determine the variation in emitted mercury. Feed coal samples were analyzed for proximate, calorific value and Hg content, while fly ash samples were examined for C and Hg contents. The maceral content of the feed coal was also determined. The emitted mercury was calculated and compared to mercury emitted from the stack according to a mass-balance calculation from a previous study for the same station. Mercury contents ranged from 0.029 to 0.066 mg/kg for feed coal, and from 0.069 to 0.112 mg/kg for fly ash. The carbon/char in fly ash was separated into reactive (vitrinitic/bimacerate) and less reactive (inertinitic) chars using ZnBr{sub 2} at specific gravities of 1.7, 2.0, and 2.25 to 2.4. The result shows that there is a positive correlation between the carbon and mercury content of the fly ash. The reactive char particles in the fly ash may be responsible for the capture mercury in fly ash. The percentage of estimated captured mercury by fly ash increases with increasing carbon content (%) in fly ash. The percentage of emitted mercury for the period of 38 weeks is estimated to be within the range of 49% to 76% of the total input of mercury. (author)

    Background Anaplastic Lymphoma Kinase (ALK) positivity represents a novel molecular target in a subset of Non-Small Cell Lung Cancers (NSCLC). We explore Fluorescence in situ Hybridization (FISH) and Immunohistochemistry (IHC) as diagnostic methods for ALK positive patients and to describe its prevalence and outcomes in a population of NSCLC patients. Methods NSCLC patients previously screened for Epidermal Growth Factor Receptor (EGFR) at our institution were selected. ALK positive patients were identified by FISH and the value of IHC (D5F3) was explored. Results ninety-nine patients were identified. Median age was 61.5 years (range 35–83), all were caucasians, eighty percent were adenocarcinomas, fifty-one percent were male and thirty-eight percent were current smokers. Seven (7.1%) patients were ALK positive by FISH, thirteen (13.1%) were EGFR mutant, and 65 (65.6%) were negative/Wild Type (WT) for both ALK and EGFR. ALK positivity and EGFR mutations were mutually exclusive. ALK positive patients tend to be younger than EGFR mutated or wt patients. ALK positive patients were predominantly never smokers (71.4%) and adenocarcinoma (71.4%). ALK positive and EGFR mutant patients have a better outcome than negative/WT. All patients with ALK FISH negative tumours were negative for ALK IHC. Out of 6 patients positive for ALK FISH with more tissue available, 5 were positive for ALK IHC and 1 negative. Conclusions ALK positive patients represent 7.1% of a population of selected NSCLC. ALK positive patients have different clinical features and a better outcome than EGFR WT and ALK negative patients. IHC is a promising method for detecting ALK positive NSCLC patients. PMID:23359795

    Full Text Available Esophageal cancer is one of the most common malignancies in our country. Patients often seek medical advice in advanced and inoperable stages or with cervical esophageal cancer, in which operation is accompanied by sever morbidity. In this conditions many of them cannot tolerate chemo-radiation, or refuse it. Therefore radiotherapy is applied as a single modality in palliation of many patients with esophageal cancer. One of the palliative radio therapeutic methods is application of 5000 CGY in 20 fractions (Long Course; but considering the great number of our patients and limited capacity of radiotherapy centers, as well as emphasis of literature on palliation with 4000 CGY in 13 fractions (short course, we decided to compare these two methods (which are both used in our departments. In this retrospective analytic study, the files of 283 patients with esophageal cancer referred to cancer institute of Imam Khomeini Hospital from 1989-1999 were studied. Patients were between 27-97 years old (mean age=58.3 and most of them were male (53.7 percent. The mean length of lesion was 8.5 cm. The most common site of lesion was middle third at esophagus (48.1 percent and the most common pathology was squamous cell carcinoma (99.6 percent. Fifty-four percent of patients were hot tea drinkers habitually. From the mentioned variables, only length of lesion had significant relationship with overall survival (P=0.04. Thirty-eight of 283 patients were excluded from analytic study because of incomplete follow-up. The number of patients had been treated by long course (5000 CGY in 20 fractions was 137 and the remainder (108 patients by short course (4000 CGY in 13 fractions. No significant difference was seen statistically between these two groups in overall and dysphagia-free survival (Kaplan-Meyer test. Also total dosage of spinal cord is lower in the short course. Thus regarding to less required time in short course and comparable palliation and survival between

    Objective A survey was held to establish whether laypeople knew the location of their temporomandibular joint. Methods A sample of 61 participants, visiting their dental office for a routine check-up, was given a three-question survey of whether they knew the location of their temporomandibular joint and could point to this location. Results Thirty-eight participants answered the question affirmatively. Only 13 pointed to the correct location. Of these, six participants received consultation for TMD in the past, three participants were healthcare providers, and four participants actually had knowledge of the exact location. Out of 23 participants who did not know the location, one accidently designated the correct position. Conclusion The location of the temporomandibular joint is not a well-known site for many patients. In the presence of orofacial pain, it seems advisable to let the patient designate and record the site of the pain on a drawing on the patient chart.

    OBJECTIVE: The goal of this article was to describe the clinical characteristics and outcomes of patients diagnosed with psychogenic nonepileptic seizures (PNES). METHODS: We conducted a retrospective review of patients diagnosed with PNES in a 5-year period. RESULTS: Fifty patients with PNES were identified, giving an estimated incidence of 0.91\\/100,000 per annum. Thirty-eight were included for review, 15 of whom were male (39%). Eighteen patients had been diagnosed with epilepsy as well as PNES (47%). We demonstrated a gender difference in our patients, with males having higher seizure frequencies, more antiepileptic drug use, and a longer interval before diagnosis of PNES. Females were diagnosed with other conversion disorders more often than males. Impaired social function was observed in PNES, as was resistance to psychological interventions with a subsequent poor response to treatments. CONCLUSIONS: PNES remains a difficult condition to treat, and may affect males in proportions higher than those described in previous studies.

  14. Methods of patient warming during abdominal surgery.

    Li Shao

    Full Text Available BACKGROUND: Keeping abdominal surgery patients warm is common and warming methods are needed in power outages during natural disasters. We aimed to evaluate the efficacy of low-cost, low-power warming methods for maintaining normothermia in abdominal surgery patients. METHODS: Patients (n = 160 scheduled for elective abdominal surgery were included in this prospective clinical study. Five warming methods were applied: heated blood transfusion/fluid infusion vs. unheated; wrapping patients vs. not wrapping; applying moist dressings, heated or not; surgical field rinse heated or not; and applying heating blankets or not. Patients' nasopharyngeal and rectal temperatures were recorded to evaluate warming efficacy. Significant differences were found in mean temperatures of warmed patients compared to those not warmed. RESULTS: When we compared temperatures of abdominal surgery patient groups receiving three specific warming methods with temperatures of control groups not receiving these methods, significant differences were revealed in temperatures maintained during the surgeries between the warmed groups and controls. DISCUSSION: The value of maintaining normothermia in patients undergoing abdominal surgery under general anesthesia is accepted. Three effective economical and practically applicable warming methods are combined body wrapping and heating blanket; combined body wrapping, heated moist dressings, and heating blanket; combined body wrapping, heated moist dressings, and warmed surgical rinse fluid, with or without heating blanket. These methods are practically applicable when low-cost method is indeed needed.

Thirty-three patients (thirty-eight eyes with PAC or PACG status post patent laser iridotomy and maintained normal intraocular pressure (IOP but with positive DRPT results were enrolled. All the subjects were treated with krypton LPIP. DRPT was repeated after krypton LPIP. Results of DRPT were recorded. The visual acuity, IOP and gonioscopy were analyzed before and after krypton LPIP. A minimum time limit for follow-up was 6mo.RESULTS:Thirty-three patients (thirty-eight eyes were followed for 17.7±8.37mo (range 7-41mo after LPIP. Positive results of DRPT decreased from 38 eyes to 9 eyes (23.7% after LPIP. Peripheral anterior synechiae of angle in 34 of 38 eyes (89.5% remained unchanged at dynamic gonioscopy throughout the follow-up period after LPIP.CONCLUSION:LPIP decreased positive rates of the DRPT significantly. The mechanism may be that LPIP minimized contact between the peripheral iris and trabecular meshwork, which is a key factor for developing peripheral anterior synechiae.

    Full Text Available BACKGROUND: Essure is a permanent transcervical sterilisationprocedure. Three months after the procedure a confirmation test is performed to evaluate tubal occlusion or microinsert location. During this period the tubal lumen is occluded by benign tissue ingrowth stimulated by the microinsert. Since 2007, 169 procedures have been performed at University Medical Centre Maribor. The purpose of our study was to evaluate the efficacy, satisfaction, and complications of the procedure.METHODS: Thirty-eight consecutive patients were included in prospective study. All procedures were performed between August 2012 and March 2013 by the same experienced hysteroscopist in an outpatient setting. Transvaginal 2D ultrasound was performed 3 months after the procedure to asses the position of microinserts. Hysterosalpingo foam sonography (HyFoSy was performed in 5 cases and hysterosalpingography (HSG was performed once in a total of 6 cases with indeterminate position of microinserts.RESULTS: Thirty-eight patients with 75 Fallopian tubes were included. Essure microinsert was successfully placed in 73 of 75 Fallopian tubes in 37 patients (97,3%. Transvaginal ultrasound demonstrated a correct placement of 67 microinserts (67/73, 91,8%. Tubal occlusion was confirmed in all 6 cases with indeterminate position of microinserts. The overall patient satisfactory rate was 9,92 on a scale from 0 to 10.CONSCLUSION: Essure is a method for permanent female contraception that has a very high rate of success and patient satisfaction, a low rate of complications and is well tolerated. In cases of indeterminate position of microinserts on transvaginal ultrasound, HyFoSy could be an alternative to HSG.

    1984-09-01

    Thirty eight patients of geriatric dementia (mean age 74.9 years) were examined by computerized tomography (CT) and their intellectual functions and activities of daily living (ADL) were evaluated. CT was evaluated by both visual assessment method and direct measuring method. Intellectual function was evaluated by Jikei University dementia rating scale. ADL was evaluated by both Hasegawa's rating scale and Sengoku's rating scale. Results were as follows: significant influence by age was observed in intellectual functions and ADL of subjects above 75 years old. There were good correlations between the higher intellectual function, the better grooming and hygiene, and less needs of nursing care. The severe brain atrophy evaluated by the visual assessment method was correlated with the depressed level of intellectual function. When brain atrophy is mild despite high degree of dementia, reexamination should be made to explore somatic diseases inducing depression of mental activity. It also should be noted that sex and age difference is important in studying geriatric patients.

    The screening of ROS proto-oncogene 1, receptor tyrosine kinase(ROS1) fusion rearrangement might be potentially beneficial for an effective therapy against non-small cell lung cancer (NSCLC). However, the three main ROS1 rearrangement detection methods have limitations, and no routine protocol for the detection of ROS1 rearrangement in NSCLC is available. In this study, our aims were to compare immunohistochemistry (IHC), fluorescent in situ hybridization (FISH) and quantitative real-time polymerase chain reaction (qRT-PCR) in their ability to detect ROS1 rearrangement in NSCLC, and discuss the clinical characteristics and histopathology of the patients with ROS1 rearrangement. Moreover, the effects of tyrosine kinase inhibitors (TKIs) therapy on the patients with ROS1 rearrangement and advanced stage disease (III b–IV) were investigated. Patients with a previously diagnosed NSCLC were recruited in this study from November 2013 to October 2015. IHC was performed using the D4D6 monoclonal antibody (mAb) in an automatic IHC instrument, while FISH and qRT-PCR were carried out to confirm the IHC results. FISH and qRT-PCR positive cases underwent direct sequencing. After detection, patients with advanced ROS1 rearranged NSCLC had received TKI therapy. Two hundred and thirty-eight patients were included in this study. ROS1 rearrangement was detected in 10 patients. The concordant rate of FISH and qRT-PCR results was 100 %, while in the FISH and IHC results high congruence was present when IHC showed a diffusely (≥60 % tumor cells) 2–3+ cytoplasmic reactivity pattern. Patients harboring ROS1 rearrangement were mostly young (8/10), females (7/10) and non-smokers (7/10) with adenocarcinoma (10/10) and acinar pattern. Most of their tumor were in intermediate grade (6/8). Among these 10 patients, three of them in stage IV with ROS1 rearrangement gained benefits from ROS1 TKI therapy. IHC, FISH and qRT-PCR can reliably detect ROS1 rearrangement in NSCLC, while IHC can be

    Full Text Available Abstract Background A standard intra-operative procedure for assessing sentinel lymph node metastasis in breast cancer patients has not yet been established. Patients and methods One hundred and thirty-eight patients with stage I breast cancer who underwent sentinel node biopsy using both imprint cytology and frozen section were analyzed. Results Seventeen of the 138 patients had sentinel node involvement. Results of imprint cytology included nine false negative cases (sensitivity, 47.1%. In contrast, only two cases of false negatives were found on frozen section (sensitivity, 88.2%. There were two false positive cases identified by imprint cytology (specificity, 98.3%. On the other hand, frozen section had 100% specificity. Conclusion These findings suggest that frozen section is superior to imprint cytology for the intra-operative determination of sentinel lymph node metastasis in stage I breast cancer patients.

    To provide adequate care, medical professionals have to collect not only medical information but also information that may be related to private aspects of the patient's life. With patients' increasing awareness of information privacy, healthcare providers have to pay attention to the patients' right of privacy. This study aimed to clarify the requirements of the display method of electronic patient record (EPR) screens in consideration of both patients' information privacy concerns and health professionals' information needs. For this purpose, semi-structured group interviews were conducted of 78 medical professionals. They pointed out that partial concealment of information to meet patients' requests for privacy could result in challenges in (1) safety in healthcare, (2) information sharing, (3) collaboration, (4) hospital management, and (5) communication. They believed that EPRs should (1) meet the requirements of the therapeutic process, (2) have restricted access, (3) provide convenient access to necessary information, and (4) facilitate interprofessional collaboration. This study provides direction for the development of display methods that balance the sharing of vital information and protection of patient privacy.

Nutritional support is one way to improve the condition of these critically ill patients. We performed a prospective randomized study on the effect of early nutritional support in severely injured patients admitted to the Division of Traumatic Surgery, Siriraj Hospital between June 1992 and January 1994. Thirty-eight severe traumatic patients with ISS between 20-40 were randomly divided into control and study group. The 17 patients in the control group were treated in the conventional method with administration of hypo caloric intravenous regimen and supplement with oral diet as soon as the bowel function was returned. The 21 patients of the study group were fed either by enteral or parenteral feeding or both with an appropriate caloric and protein requirement as soon as hemodynamic status was stabilized. We found the study group had a lower mortality rate, a lower complication rate, a shorter period of ICU stay, and an earlier weaning from the ventilator than the control group. The study group also lost less weight than the control group. Nitrogen balance in the study group was significantly lower than the control group.

    Contrast induced nephropathy (CIN) is the third lead cause of hospital acquired renal failure and was associated with significant morbidity and mortality. We hypothesized that hypertension is an independent risk factor for the development of CIN in patients undergoing elective percutaneous coronary intervention (PCI). The case-control method was used, 138 patients scheduled for elective PCI. We measured serum creatinine at baseline and after 24 hours of the procedure. CIN was defined as arising in serum creatinine of at least 44 μmol/l (0,5 mg/dl) or 25% rise from baseline. All patients received low osmolality nonionic contrast during PCI. Hypertension was defined as self-reported a history of treated or untreated diagnosed high blood pressure. One hundred thirty-eight patients (74,6%) were male, and 35 patients (25,4%) were female. Among the 138 patients, 86 (62,3%) were hypertensive patients whereas 52 (37,7%) were nonhypertensive patients. There was no difference in baseline serum creatinine levels and the amount of contrast media in patient with and without CIN. CIN developed in 42 patients, 39 patients (92,9%) were hypertensive compared to 3 patients (7,1%) without hypertension with p value < 0,05. (Odds ratio 16,8, 95% CI 4.542 - 62,412). This study showed that hypertension was a risk factor for the development of CIN

    Full Text Available This work proposes to predict target genes and pathways for uveal melanoma (UM based on an ensemble method and pathway analyses. Methods: The ensemble method integrated a correlation method (Pearson correlation coefficient, PCC, a causal inference method (IDA and a regression method (Lasso utilizing the Borda count election method. Subsequently, to validate the performance of PIL method, comparisons between confirmed database and predicted miRNA targets were performed. Ultimately, pathway enrichment analysis was conducted on target genes in top 1000 miRNA-mRNA interactions to identify target pathways for UM patients. Results: Thirty eight of the predicted interactions were matched with the confirmed interactions, indicating that the ensemble method was a suitable and feasible approach to predict miRNA targets. We obtained 50 seed miRNA-mRNA interactions of UM patients and extracted target genes from these interactions, such as ASPG, BSDC1 and C4BP. The 601 target genes in top 1,000 miRNA-mRNA interactions were enriched in 12 target pathways, of which Phototransduction was the most significant one. Conclusion: The target genes and pathways might provide a new way to reveal the molecular mechanism of UM and give hand for target treatments and preventions of this malignant tumor.

    Postpartum discharge instructions are a crucial part of a mother's birth experience. Finding the method to provide those discharge instructions in a manner that increases the mother's satisfaction with her hospital experience is important. This quasi-experimental study examined the relationship between new mothers' interaction with nurses providing postpartum instructions by the traditional and class methods and their satisfaction with discharge teaching. The results indicated new mothers were satisfied with both methods of discharge teaching; however, they were more likely to report stronger agreement with overall satisfaction with the traditional method of discharge teaching than with attending the discharge class.

    Full Text Available Abstract Background Studies on gastrointestinal symptoms, dysfunctions, and neurological disorders in systemic scleroderma are lacking so far. Methods Thirty-eight scleroderma patients (34 limited, 4 diffuse, 60 healthy controls and 68 dyspeptic controls were scored for upper and lower gastrointestinal symptoms (dyspepsia, bowel habits, gastric and gallbladder emptying to liquid meal (functional ultrasonography and small bowel transit (H2-breath test. Autonomic nerve function was assessed by cardiovascular tests. Results The score for dyspepsia (mainly gastric fullness was greater in scleroderma patients than healthy controls, but lower than dyspeptic controls who had multiple symptoms, instead. Scleroderma patients with dyspepsia had a longer disease duration. Fasting antral area and postprandial antral dilatation were smaller in scleroderma patients than dyspeptic and healthy controls. Gastric emptying was delayed in both scleroderma patients (particularly in those with abnormal dyspeptic score and dyspeptic controls, who also showed a larger residual area. Despite gallbladder fasting and postprandial volumes were comparable across the three groups, gallbladder refilling appeared delayed in dyspeptic controls and mainly dependent on delayed gastric emptying in scleroderma. Small intestinal transit was also delayed in 74% of scleroderma and 66% of dyspeptic controls. Bowel habits were similar among the three groups. Autonomic neuropathy was not associated with dyspepsia, gastric and gallbladder motility and small intestinal transit. Conclusion In scleroderma patients dyspepsia (mainly gastric fullness, restricted distension of the gastric antrum and diffuse gastrointestinal dysmotility are frequent features. These defects are independent from the occurrence of autonomic neuropathy.

    Introduction Cognitive and behavioral impairments are common in patients with abnormal thyroid function; these impairments cause a reduction in their quality of life. The current study investigates the decision making performance in patients with hyperthyroidism to explore the possible mechanism of their cognitive and behavioral impairments. Methods Thirty-eight patients with hyperthyroidism and forty healthy control subjects were recruited to perform the Iowa Gambling Task (IGT), which assessed decision making under ambiguous conditions. Results Patients with hyperthyroidism had a higher score on the Zung Self-Rating Anxiety Scale (Z-SAS), and exhibited poorer executive function and IGT performance than did healthy control subjects. The patients preferred to choose decks with a high immediate reward, despite a higher future punishment, and were not capable of effectively using feedback information from previous choices. No clinical characteristics were associated with the total net score of the IGT in the current study. Conclusions Patients with hyperthyroidism had decision-making impairment under ambiguous conditions. The deficits may result from frontal cortex and limbic system metabolic disorders and dopamine dysfunction. PMID:26090955

    Full Text Available Background: Chronic obstructive pulmonary disease (COPD is the only cause of death from chronic disease that will increase worldwide until 2020 and it represents a big burden for patients and society. Patients with COPD characteristically show poor exercise performance indicated by a marked reduction in both peak pulmonary 02 uptake and work rate at peak exercise. The sequelae of exercise intolerance include increased difficulty in performing daily tasks, etc. The objective of the study is to investigate the influence of thoracic and upper limb muscle function on 6-min walk distance (6MWD in patients with COPD. Method: Thirty eight COPD patients were included if they fulfilled the criteria for COPD according to the Global Initiative for Chronic Obstructive Lung Disease guidelines. Prospective, cross-sectional design with sample size of 38 patients. All patients performed 6MWD and 1RM exercises. Results: To study the correlation between variables, Pearson or Spearman coefficients of correlation were used with the level of statistical significance set at 5%.Results of this study suggested for the first time that thoracic muscle strength is a predictor of 6MWD in COPD patients. It also confirms the influence of respiratory muscle strength (Pimax, dyspnea, on the 6MWD of these patients. Conclusion: It is concluded that peripheral muscle strength, respiratory muscle strength, and the sensation of dyspnea all have an influence on the capacity of COPD patients to perform exercises.

    Ovulatory dysfunction is a group of disorders with variable clinical presentations occasionally having serious long-term adverse effects. It accounts for 30% of female fertility problems. Evidence suggests an association between an individual's weight and disorders of ovulation. The objective of our study was to describe the clinical and hormonal profile of subfertile women with ovulatory dysfunction in relation to their body mass index (BMI). Methods: This prospective, descriptive study was carried out in Mother and Child Health Centre, PIMS, Islamabad and Railway hospital, Rawalpindi from April 2001 to March 2007. One hundred and thirty eight infertile patients with ovulatory dysfunction were included. The clinical data including BMI of each patient was recorded in addition to reports of investigations comprised of cervical smear, pelvic ultrasound and hormonal profile. Results: Primary infertility was found in 61% while secondary in 39% of the patients. The mean age was 29 years and mean duration of infertility was 6 years. Menstrual pattern was normal in 56.5%. BMI was normal in 30.4% while most patients were overweight and obese. Prolonged cycles, history of systemic endocrine disorders, abnormal vaginal discharge, hirsutism, polycystic ovarian morphology and hormonal abnormalities were more frequent in patients with increased BMI. During the study period, 21.7% of the women conceived. Conclusion: Infertile patients with ovulatory dysfunction present more frequently with primary infertility. They usually have higher than required BMI. Oligomenorrhoea amenorrhoea, hirsutism and hormonal abnormalities are more frequent in overweight than infertile patients with ovulatory dysfunction having a normal BMI. (author)

    Background: Catheter-related infections (CRIs) are a significant source of morbidity and mortality in hemodialysis patients. The identification of novel, modifiable risk factors for CRIs may lead to improved outcomes in this population. Peripherally inserted central catheters (PICCs) have been hypothesized to compromise vascular access due to vascular damage and venous thrombosis, whereas venous thrombosis has been linked to the development of CRIs. Here we examine the association between PICC placement and CRIs. Methods: A retrospective review was performed of all chronic hemodialysis catheter placements and exchanges performed at a large university hospital from September 2003 to September 2008. History of PICC line use was determined by examining hospital radiologic records from December 1993 to September 2008. Catheter-related complications were assessed and correlated with PICC line history. Results: One hundred eighty-five patients with 713 chronic tunneled hemodialysis catheter placements were identified. Thirty-eight of those patients (20.5%) had a history of PICC placement; these patients were more likely to have CRIs (odds ratio = 2.46, 95% confidence interval = 1.71–3.53, p < .001) compared with patients without a history of PICC placement. There was no difference between the two groups in age or number of catheters placed. Conclusion: Previous PICC placement may be associated with catheter-related infections in hemodialysis patients.

    Aim: We examined the habits and practices of mobile phone use by patients in KwaZulu-Natal, South Africa. Methods: We conducted a descriptive survey of two patient populations: 137 urban patients attending private practitioners and 139 patients in remote rural areas attending outpatient departments in Government-funded hospitals. The questionnaire covered several domains: demographics, mobile phone use, privacy and confidentiality and future use for health-related matters. Results: Two hundred and seventy-six patients completed the questionnaire. We found that a third of our participants shared their mobile phone with others, 24% lent their phone to others and more than half received health-related messages for other people. Mobile phone theft was common, as was number changing. Thirty-eight percent of the people were not able to afford airtime for more than a week in the past year and 22% of rural patients were unable to keep their phone charged. Mobile phone signal coverage was significantly worse in the rural areas than in urban areas. Conclusion: This study highlights the legal and ethical ramifications that these practices and findings will have on mHealth programmes in our setting. Healthcare providers and regulators will need to consider how patients use and manage their mobile phones when developing services and regulations.

    Background: The success of randomized-controlled stroke trials is dependent on the recruitment and retention of a sufficient number of patients, but fewer than half of all trials meet their target number of patients. Methods: We performed a search and review of the literature, and conducted...... a survey and workshop among 56 European stroke trialists, to identify barriers, suggest methods to improve recruitment and retention, and make a priority list of interventions that merit further evaluation. Results: The survey and workshop identified a number of barriers to patient recruitment...... and retention, from patients’ incapacity to consent, to handicaps that prevent patients from participation in trial-specific follow-up. Methods to improve recruitment and retention may include simple interventions with individual participants, funding of research networks, and reimbursement of new treatments...

    Teaching students to communicate effectively with patients has always been part of the radiography curriculum in the USA. However, developing these skills has become even more important in recent times due to several factors. Patients who have been well versed in what to expect from the examination being conducted are in a better position to co-operate with the radiographer. This increases the chances of producing optimal results from an examination at the first attempt, thus reducing radiation exposure, patient discomfort and the overall cost of conducting the procedure. Also, increased competition among health care providers has resulted in more emphasis being placed on patient, or customer, satisfaction. Radiographers are in the 'front line' of patient care. Patients often have more interaction with radiographers than with physicians or other medical specialists. Radiographers who practise effective communication techniques with their patients can alleviate anxiety and make an important contribution to the overall satisfaction of the patient with respect to the quality of service and care they receive. This article describes instructional methods being used in the USA to help develop effective patient communication techniques, and reports the findings of a study among radiography educators as to which of these methods are thought to be most successful.

    In this systematic review, we aimed to synthesize data that identify factors contributing to patient satisfaction in dermatology care using qualitative methods. We performed a comprehensive search of the literature using the PubMed database for articles published between January 1, 2000 and February 9, 2015. The initial search yielded 186 articles, of which 13 were included after applying inclusion and exclusion criteria. The systematic review of 13 articles included a total of 330 patients. Using in-field observations and semistructured interviews, studies found that qualitative methods and analysis increased the provider's sensitivity to patient needs and enhanced patient care. Analyses using qualitative methods found increased patient satisfaction in their healthcare provider is associated with (1) confidence in the provider's diagnosis, (2) perception of patient-centered, individualized recommendations and (3) quality of patient education and provider explanation during a visit. Patient satisfaction is measured using either quantitative or qualitative methods. Quantitative methods result in standardized data that often does not capture the nuances of patient experience. In contrast, qualitative methodology is integral to gathering patient perspectives on patient care and satisfaction and should be included in future research models.

    A randomised controlled trial was used to evaluate elective ambulatory orthopaedic surgery patients' emotions during internet-based patient education or face-to-face education with a nurse. The internet-based patient education was designed for this study and patients used websites individually based on their needs. Patients in the control group participated individually in face-to-face patient education with a nurse in the ambulatory surgery unit. The theoretical basis for both types of education was the same. Ambulatory orthopaedic surgery patients scored their emotions rather low at intervals throughout the whole surgical process, though their scores also changed during the surgical process. Emotion scores did not decrease after patient education. No differences in patients' emotions were found to result from either of the two different patient education methods.

    PurposeTo explore the efficacy and safety of prophylactic temporary balloon occlusion of the infrarenal abdominal aorta during caesarean for the management of patients with placenta praevia accreta.MethodsTwo hundred and sixty-eight cases of placenta praevia accreta from January 2012 to June 2015 were retrospectively reviewed. Group A included two hundred and thirty patients who underwent prophylactic temporary balloon occlusion of infrarenal abdominal aorta followed by caesarean section. Group B included thirty-eight patients who underwent caesarean without endovascular intervention. The parameters including operating room time, estimated blood loss, blood transfusion volume, PT (prothrombin time) during operation, days in the intensive care unit, and total hospital days were compared between the two groups.ResultsThe operating room time, estimated blood loss, PT, the incidence of hysterectomy, blood transfusion volume, postpartum haemorrhage, and days in intensive care unit were lower in group A than in group B, with statistical significance (P   0.05). No patient in the group with prophylactic temporary balloon occlusion of the infrarenal abdominal aorta was performed hysterectomy, while three patients in group B were performed hysterectomy because of uncontrollable haemorrhage.ConclusionsThe results indicate that prophylactic temporary balloon occlusion of infrarenal abdominal aorta followed by caesarean section is safe and effective to control intraoperative blood loss and greatly decreases the risk of hysterectomy in patients with placenta praevia accreta.

    The Patient-Centered Outcomes Research Institute (PCORI), created to fund research guided by patients, caregivers, and the broader health care community, offers a new research venue. Many (41 of 50) first funded projects involved qualitative research methods. This study was completed to examine the current state of the science of qualitative methodologies used in PCORI-funded research. Principal investigators participated in phenomenological interviews to learn (a) how do researchers using qualitative methods experience seeking funding for, implementing and disseminating their work; and (b) how may qualitative methods advance the quality and relevance of evidence for patients? Results showed the experience of doing qualitative research in the current research climate as "Being a bona fide qualitative researcher: Staying true to research aims while negotiating challenges," with overlapping patterns: (a) researching the elemental, (b) expecting surprise, and (c) pushing boundaries. The nature of qualitative work today was explicitly described and is rendered in this article.

    Full Text Available Aim: This study was a qualitative study that investigated the exercise prescription method in knee osteoarthritis patients in Malaysia. It purposed to find out the most common and effective method used by physiotherapist in prescribing exercises for knee osteoarthritis patients in Malaysia. Method: This study used a self-administered survey questionnaire. The subjects recruited for this study were diagnosed with knee osteoarthritis, age range of between 50 to 80 years old.The methods of delivery were divided into three categories, which include only verbal instructions, verbal instruction together with demonstration and lastly a combination of all three methods including verbal instruction, demonstration and handouts with diagrams. Results: The results showed that 52% received their exercise prescription with verbal instruction and together with demonstration, about 43% of them received all three types of methods which included the verbal instruction, demonstration and take home handouts and 5% of them only received verbal instruction. Out of 5% who received verbal instruction alone, only 1% understood the exercises and the remaining 4% did not and 45% out of 52% who received verbal and demonstration method understood the exercises and the remaining 7% did not. 5% who received only verbal instruction did not seem to continue the exercises at home. 52% received verbal instruction together with demonstration, with about 44% of them having continued their exercises but the remaining 8% did not. 43% who received all three methods reported to continue. Conclusion: The best method of delivering exercises to knee osteoarthritis patients was proven to be the method with a combination of verbal instruction, demonstration together with a take home handout. This method showed very positive outcome and should be implemented and emphasized more in both the government and private sectors of physiotherapy departments.

    Thirty eight patients of geriatric dementia (mean age 74.9 years) were examined by computerized tomography (CT) and their intellectual functions and activities of daily living (ADL) were evaluated. CT was evaluated by both visual assessment method and direct measuring method. Intellectual function was evaluated by Jikei University dementia rating scale. ADL was evaluated by both Hasegawa's rating scale and Sengoku's rating scale. Results were as follows: significant influence by age was observed in intellectual functions and ADL of subjects above 75 years old. There were good correlations between the higher intellectual function, the better grooming and hygiene, and less needs of nursing care. The severe brain atrophy evaluated by the visual assessment method was correlated with the depressed level of intellectual function. When brain atrophy is mild despite high degree of dementia, reexamination should be made to explore somatic diseases inducing depression of mental activity. It also should be noted that sex and age difference is important in studying geriatric patients. (author)

    Pilates is an exercise method which increases strength and endurance of core muscles and improves flexibility, dynamic postural control and balance. To analyze and compare the effects of Mat and Reformer Pilates methods in Patients with Multiple Sclerosis (MS). Thirty-eight patients with MS were included in the study. Participants were randomly divided into 3 groups as Mat Pilates, Reformer Pilates and control groups. The subjects in the Pilates groups did Mat or Reformer Pilates for 8 weeks, 2 days a week. The control group did breathing and relaxation exercises at home. Balance, functional mobility, core stability, fatigue severity and quality of life were evaluated. Balance, functional mobility, core stability, fatigue severity and quality of life improved after Pilates in Mat and Reformer Pilates groups (p  0.05). When the gain obtained in the Pilates groups is compared, it has been observed that progress has been more in trunk flexor muscle strength in the Reformer Pilates group (p  0.05). As a result, patients with MS have seen similar benefits in Reformer Pilates and Mat Pilates methods.

    In Denmark, patients being treated on Haematology Outpatients Departments get instructed to self-manage their blood sample collection from Central Venous Catheter (CVC). However, this is a complex and risky procedure, which can jeopardize patient safety. The aim of the study was to suggest a method for developing standard digital patient education programs for patients in self-administration of blood samples drawn from CVC. The Design Science Research Paradigm was used to develop a digital patient education program, called PAVIOSY, to increase patient safety during execution of the blood sample collection procedure by using videos for teaching as well as procedural support. A step-by-step guide was developed and used as basis for making the videos. Quality assurance through evaluation with a nurse was conducted on both the step-by-step guide and the videos. The quality assurance evaluation of the videos showed; 1) Errors due to the order of the procedure can be determined by reviewing the videos despite that the guide was followed. 2) Videos can be used to identify errors - important for patient safety - in the procedure, which are not identifiable in a written script. To ensure correct clinical content of the educational patient system, health professionals must be engaged early in the development of content and design phase.

    Following the WHO initiative named World Alliance for Patient Safety (PS) launched in 2004 a conceptual framework developed by PS national reporting experts has summarized the knowledge available. As a second step, the Department of Public Health of the University of Saint Etienne team elaborated a Categorial Structure (a semi formal structure not related to an upper level ontology) identifying the elements of the semantic structure underpinning the broad concepts contained in the framework for patient safety. This knowledge engineering method has been developed to enable modeling patient safety information as a prerequisite for subsequent full ontology development. The present article describes the semantic dissection of the concepts, the elicitation of the ontology requirements and the domain constraints of the conceptual framework. This ontology includes 134 concepts and 25 distinct relations and will serve as basis for an Information Model for Patient Safety.

Little has been published regarding the method of payment for patient participation. As clinical trials move into widely dispersed community practices and more complex designs, the method of payment also becomes more complex. Here we review the decision process and payment method selected for a primary care-based randomized clinical trial of asthma management in Black Americans.Methods: The method selected is a credit card system designed specifically for clinical trials that allows both fixed and variable real-time payments. We operationalized the study design by providing each patient with two cards, one for reimbursement for study visits and one for payment of medication costs directly to the pharmacies.Results: Of the 1015 patients enrolled, only two refused use of the ClinCard, requesting cash payments for visits and only rarely a weekend or fill-in pharmacist refused to use the card system for payment directly to the pharmacy. Overall, the system has been well accepted by patients and local study teams. The ClinCard administrative system facilitates the fiscal accounting and medication adherence record-keeping by the central teams. Monthly fees are modest, and all 12 study institutional review boards approved use of the system without concern for patient

    Purpose: To investigate two event-oriented methods for evaluating patient satisfaction with radiological services like outpatient computed tomography (CT) examinations. Materials and Methods: 159 patients (55 % men, 45 % women) were asked to complete a questionnaire to provide information about their satisfaction with their examination. At first, patients were asked to spontaneously recall notably positive and negative aspects (so-called 'critical incidents', critical incident technique = CIT) of the examination. Subsequently a flow chart containing all single steps of the examination procedure was shown to all patients. They were asked to point out the positive and negative aspects they perceived at each step (so-called sequential incident technique = SIT). Results: The CIT-based part of the questionnaire yielded 356 comments (183 positive and 173 negative), which were assigned to one of four categories: interaction of staff with patient, procedure and organization, CT examination, and overall setting of the examination. Significantly more detailed comments regarding individual aspects of the CT examination were elicited in the second part of the survey, which was based on the SIT. There were 1413 statements with a significantly higher number of positive comments (n = 939, 66 %) versus negative comments (n = 474, 34 %; p < 0.001). Conclusion: The critical and sequential incident techniques are suitable to measure the subjective satisfaction with the delivery of radiological services such as CT examinations. Positive comments confirm the adequacy of the existing procedures, while negative comments provide direct information about how service quality can be improved. (orig.)

    Patients increasingly use the Internet to research health-related issues. Internet content, unlike other forms of media, is not regulated. Although information accessed online can impact patients' opinions and expectations, there is limited information about the quality or readability of online orthopaedic information. PubMed, MEDLINE, and Google Scholar were searched using anatomic descriptors and three title keywords ("Internet," "web," and "online"). Articles examining online orthopaedic information from January 1, 2000, until April 1, 2015, were recorded. Articles were assessed for the number of reviewers evaluating the online material, whether the article examined for a link between authorship and quality, and the use of recognized quality and readability assessment tools. To facilitate a contemporary discussion, only publications since January 1, 2010, were considered for analysis. A total of thirty-eight peer-reviewed articles published since 2010 examining the quality and/or readability of online orthopaedic information were reviewed. For information quality, there was marked variation in the quality assessment methods utilized, the number of reviewers, and the manner of reporting. To date, the majority of examined information is of poor quality. Studies examining readability have focused on pages produced by professional orthopaedic societies. The quality and readability of online orthopaedic information are generally poor. For modern practices to adapt to the Internet and to prevent misinformation, the orthopaedic community should develop high-quality, readable online patient information.

    2017-01-01

    Background Nursing educators must be qualified to teach patient safety to nursing students to ensure patient safety in the clinical field. The purpose of this study was to assess nursing educators’ competencies and educational needs for patient safety in hospitals and nursing schools. Method A mixed-methods sequential explanatory design employed a survey and focus group interview with nursing educators (school clinical instructors and hospital nurse preceptors). Thirty-eight questionnaires filled out by clinical instructors from six four-year nursing universities and 106 questionnaires from nurse preceptors from three high-level general hospitals in the Seoul metropolitan area were analyzed to obtain quantitative data. Focus group interviews were conducted among six clinical instructors from one nursing school and four nurse preceptors from one high-level general hospital in Seoul. Results Nursing educators had higher levels of attitude compared with relatively lower levels of skill and knowledge regarding patient safety. They reported educational needs of “medication” and “infection prevention” as being higher and “human factors” and “complexity of systems” as being lower. Nursing educators desired different types of education for patient safety. Conclusion It is necessary to enhance nursing educators’ patient safety skills and knowledge by developing and providing an integrated program of patient safety, with various teaching methods to meet their educational needs. The findings of this study provide the basic information needed to reform patient safety education programs appropriately to fit nursing educators' needs and their patient safety competencies in both clinical practice and academia. Furthermore, the findings have revealed the importance of effective communication between clinical and academic settings in making patient safety education seamless. PMID:28873099

    Piezosurgery has been used widely in oral and maxillofacial surgery, but there has been no report systematically describing an osteotomy method with piezosurgery for complicated mandibular third molar removal. The aim of this study was to introduce 4 osteotomy methods using piezosurgery and evaluate their effects. A retrospective study was conducted of patients with a complicated impacted mandibular third molar requiring extraction. The predictor variable was the extraction technique. Four osteotomy methods using piezosurgery were tested according to different impaction types: method 1 involved complete bone removal; method 2 involved segmental bone removal; method 3 involved bone removal combined with tooth splitting; and method 4 involved block bone removal. Outcome variables were success rate, operative time, major complications (including nerve injury, mandible fracture, severe hematoma, or severe edema), and serious pyogenic infection. Data were analyzed using descriptive statistics. The study was composed of 55 patients with 74 complicated impacted mandibular third molars. All impacted mandibular third molars were removed successfully. The average surgical time was 15 minutes (range, 8 to 26 minutes). Thirty-eight molars (51.4%) were extracted by method 1, 18 molars (24.3%) by method 2, 12 molars (16.2%) by method 3, and 6 molars (8.1%) by method 4. Two cases (2.7%) developed postoperative infections and recovered within 1 week using drainage and antibiotic administration. The 4 osteotomy methods with piezosurgery provide effective ways of removing complicated impacted mandibular third molars. Copyright © 2014 American Association of Oral and Maxillofacial Surgeons.

    Patient safety practices, targeting organisational changes for improving patient safety, are implemented worldwide but their costs are rarely evaluated. This paper provides a review of the methods used in economic evaluation of such practices. International medical and economics databases were searched for peer-reviewed publications on economic evaluations of patient safety between 2000 and 2010 in English and French. This was complemented by a manual search of the reference lists of relevant papers. Grey literature was excluded. Studies were described using a standardised template and assessed independently by two researchers according to six quality criteria. 33 articles were reviewed that were representative of different patient safety domains, data types and evaluation methods. 18 estimated the economic burden of adverse events, 3 measured the costs of patient safety practices and 12 provided complete economic evaluations. Healthcare-associated infections were the most common subject of evaluation, followed by medication-related errors and all types of adverse events. Of these, 10 were selected that had adequately fulfilled one or several key quality criteria for illustration. This review shows that full cost-benefit/utility evaluations are rarely completed as they are resource intensive and often require unavailable data; some overcome these difficulties by performing stochastic modelling and by using secondary sources. Low methodological transparency can be a problem for building evidence from available economic evaluations. Investing in the economic design and reporting of studies with more emphasis on defining study perspectives, data collection and methodological choices could be helpful for strengthening our knowledge base on practices for improving patient safety.

    The bone mineral content in the patients who had undergone operation for thyroid carcinoma was measured by quantitative CT. Thirty-eight cases were enrolled as the subjects. All cases were papillary adenocarcinoma of the thyroid. The totally thyroidectomized group consisted of 3 males and 14 females, and the non-totally thyroidectomized group (post-lobectomy) 3 males and 18 females. Thirty-eight healthy males and females were assigned to the control group. For evaluation of bone mineral content, quantitative CT was used and bone mineral content in the patient's lumbar vertebrae was measured. Concurrently, bone metabolic parameter in serum was determined. No significant difference was observed in the mean bone mineral content among the above three groups. To make correction by sex and age, BMC-index was defined as the value that the bone mineral content in each case was divided by the standard mean by the same age and sex. No significant difference was observed in BMC-index among the above three groups. No significant correlation was observed in serum calcitonin level with the bone mineral content and BMC-index. It suggests that no influence is exerted on bone metabolism if serum calcitonin is maintained in the physiological level. (author)

    Full Text Available Abstract Background In France outpatient centres for the care of alcoholics are healthcare establishments providing medical, psychological and social support. Although they meet the practical needs of these patients, their degree of use in each of these domains and the respective mobilisation of different skills by the care team are not well understood. Our aim was therefore to determine in detail the management involved as a function of the severity of alcohol dependence. For this purpose, all the procedures involved were compiled in a thesaurus describing its type (psychological, medical, social, reception, its scheduled or unscheduled nature, its method (face-to-face, telephone, letter and its duration. The severity of dependence was evaluated using the Addiction Severity Index (ASI. Results 45 patients were included and followed-up during 291 ± 114 days. The mean initial ASI scores (± SD were: medical (M = 0.39 ± 0.3, working-income (ER = 0.5 ± 0.3, alcohol (A = 0.51 ± 0.2, illicit drugs (D = 0.07 ± 0.08, legal (L = 0.06 ± 0.13, familial and social environment (FS = 0.34 ± 0.26, psychological (P = 0.39 ± 0.22. The total number of procedures was 1341 (29.8 per patient corresponding to 754.4 hours (16.7 per patient. The intensity of management peaked during the first month of treatment, and then declined rapidly; the maximum incidence of abstinence was observed during the 3rd month of management. Interviews with patients, group therapy and staff meetings represented 68.7%, 9.9% and 13.9% of all procedures, respectively. In patients with severe dependence, as compared to moderate, management was twice as intense in the psychological and social domains, but not in the medical domain. The ASI questionnaire was completed a second time by 24 patients, after an average of 3.2 months. The improvement was significant in the M, A, D and P domains only. Conclusion This study provided an overview of the methods employed in managing a sample of

    Purpose: To evaluate outcomes among women with American Society for Radiation Oncology (ASTRO) consensus statement cautionary features treated with brachytherapy-based accelerated partial breast irradiation (APBI). Methods and Materials: Between March 2001 and June 2006, 322 consecutive patients were treated with high-dose-rate (HDR) APBI at the University of Wisconsin. A total of 136 patients were identified who met the ASTRO cautionary criteria. Thirty-eight (27.9%) patients possessed multiple cautionary factors. All patients received 32 to 34 Gy in 8 to 10 twice-daily fractions using multicatheter (93.4%) or Mammosite balloon (6.6%) brachytherapy. Results: With a median follow-up of 60 months, there were 5 ipsilateral breast tumor recurrences (IBTR), three local, and two loco-regional. The 5-year actuarial rate of IBTR was 4.8% ± 4.1%. The 5-year disease-free survival was 89.6%, with a cause-specific survival and overall survival of 97.6% and 95.3%, respectively. There were no IBTRs among 32 patients with ductal carcinoma in situ (DCIS) vs. 6.1% for patients with invasive carcinoma (p = 0.24). Among 104 patients with Stage I or II invasive carcinoma, the IBTR rate for patients considered cautionary because of age alone was 0% vs. 12.7% in those deemed cautionary due to histopathologic factors (p = 0.018). Conclusions: Overall, we observed few local recurrences among patients with cautionary features. Women with DCIS and patients 50 to 59 years of age with Stage I/II disease who otherwise meet the criteria for suitability appear to be at a low risk of IBTR. Patients with tumor-related cautionary features will benefit from careful patient selection.

    Purpose: To evaluate different MR methods (ventricle and flow measurements) for the postoperative follow-up of hemodynamics in patients with extra- or intracardial TCPC. Materials and Methods: Twenty-eight consecutive patients (14 female, 14 male) within the ages of two to thirty-eight years were examined using a 1.5 T Gyroscan ACS-NT scanner (Philips, Best, Netherlands). 7 patients had an extracardial (eTCPC), and 21 an intracardial (iTCPC) tunnel. The calculation of the ventricular function and muscle mass was performed using 'multislice-multiphase' technique by summing up the enddiastolic and endsystolic areas; the flow measurements were evaluated by phase shift velocity mapping in the superior vena cava (SVC), inferior vena cava (IVC), right (RPA) and left (LPA) pulmonary artery. Besides peak and mean velocity, the mean and maximal flow volumes (ml/min) were calculated. Results: Ejection fraction (EF) of the functionally single ventricle was within the normal range (mean 57%) in 22/28 patients while mean muscle mass was elevated in the group with eTCPC (mean 121 g/m 2 ). The mean flow volumes and the peak velocities in all vessels were higher in the group with iTCPC as compared to the one with eTCPC. Clinically relevant retrograde flows in the IVC were only found in the group with iTCPC (7/21), as well as a significant predominant flow distribution towards the RPA (p [de

    Purpose: To determine the survival of pancreatic cancer patients treated with intraoperative radiotherapy (IORT) and/or external beam radiation therapy (EBRT) following macroscopically curative resection. Methods and Materials: One hundred and thirty-eight patients with pancreatic cancer who had undergone potentially curative total or regional pancreatectomy between 1980 and 1997 were retrospectively analyzed. Among the 138 patients, 98 had a pathologically negative surgical margin and the remaining 40 patients had a positive surgical margin. The usual EBRT dose was 45-55 Gy with a daily fraction of 1.5-2.0 Gy. The median IORT dose was 25 Gy in a single fraction. Results: The 2-year cause-specific survival rate of patients with pathologically negative surgical margins was 19%, and that of patients with positive margins was 4% (p < 0.005). Although the median survival time (MST) of patients with negative margins treated with IORT and EBRT was significantly longer than that of those treated with operation alone (17 vs. 11 months), no significant difference in survival curves was observed. In patients with positive surgical margins in peripancreatic soft tissue, the difference between the survival curve of patients treated with surgery alone and that of those treated with surgery and radiation therapy was borderline significant (p < 0.10). Patients receiving intraarterial or intraportal infusion chemotherapy had significantly improved survival rates compared with those who did not receive it (p < 0.05). Conclusion: Although the MST was longer in patients with negative margins receiving IORT and EBRT than in those receiving no radiation, improved long-term survival by IORT and/or EBRT was not suggested. In patients with positive margins, our results obtained by IORT/EBRT were encouraging. Randomized studies with much higher patient numbers are necessary to define the role of IORT in curatively resected pancreatic cancer

    Full Text Available Abstract Background Although patients with Treatment Resistant Depression (TRD often have impaired social functioning, few studies have investigated the effectiveness of psychosocial treatment for these patients. We examined whether adding group cognitive behavioral therapy (group-CBT to medication would improve both the depressive symptoms and the social functioning of patient with mild TRD, and whether any improvements would be maintained over one year. Methods Forty-three patients with TRD were treated with 12 weekly sessions of group-CBT. Patients were assessed with the Global Assessment of Functioning scale (GAF, the 36-item Short-Form Health Survey (SF-36, the Hamilton Rating Scale for Depression (HRSD, the Dysfunctional Attitudes Scale (DAS, and the Automatic Thought Questionnaire-Revised (ATQ-R at baseline, at the termination of treatment, and at the 12-month follow-up. Results Thirty-eight patients completed treatment; five dropped out. For the patients who completed treatment, post-treatment scores on the GAF and SF-36 were significantly higher than baseline scores. Scores on the HRSD, DAS, and ATQ-R were significantly lower after the treatment. Thus patients improved on all measurements of psychosocial functioning and mood symptoms. Twenty patients participated in the 12-month follow-up. Their improvements for psychosocial functioning, depressive symptoms, and dysfunctional cognitions were sustained at 12 months following the completion of group-CBT. Conclusions These findings suggest a positive effect that the addition of cognitive behavioural group therapy to medication on depressive symptoms and social functioning of mildly depressed patients, showing treatment resistance.

    No recommendations currently exist regarding implementation of both prenatal diagnosis and preimplantation genetic diagnosis (PGD) for autosomal dominant polycystic kidney disease (ADPKD). This study evaluated attitudes in ADPKD patients with either chronic kidney disease (CKD) stages I-IV or end-stage renal failure (ESRF) toward prenatal diagnosis and PGD. Ninety-six ADPKD patients were recruited from an outpatient clinic, wards, and dialysis units. Thirty-eight patients had ESRF and 58 had CKD stages I-IV. Participants were given an information sheet on prenatal diagnosis and PGD and subsequently completed a questionnaire. The median age of participants was 51.5 years. Seventeen percent of ADPKD patients with CKD and 18% of ADPKD patients with ESRF would consider prenatal diagnosis and termination of pregnancy for ADPKD. Fifty percent with CKD would have opted for PGD (or might consider it in the future) were it available and funded by the UK National Health Service, compared to 63% in the ESRF group (p = 0.33). Sixty-nine percent in the CKD group and 68% in the ESRF group believed that PGD should be offered to other patients. There was a spectrum of attitudes among this cohort. A proportion of patients believe that PGD should be made available to prospective parents with this disease. The discrepancy between the low proportion (17% CKD, 18% ESRF) who would consider prenatal diagnosis and termination of pregnancy and the higher number who hypothetically express an intention or wish to access PGD (50% CKD and 63% ESRF) indicates far greater acceptability for diagnostic methods that occur before embryo implantation. It is not known how the development of methods to identify patients whose renal function is likely to decline rapidly and treatments altering the natural history of ADPKD will affect these attitudes.

    Patient satisfaction with doctor-patient interactions is an indicator of physicians' competence. The satisfaction of diabetes patients is rarely studied in public diabetes clinics of Pakistan. Thus, this study aims to analyse the association between patient satisfaction and five dimensions of medical interaction: technical expertise, interpersonal aspects, communication, consultation time, and access/availability. A cross-sectional mixed methods study was conducted during July and August 2015 in the largest public diabetes outpatient clinic in Punjab province. We used the criterion sampling method to identify 1164 patients who: (i) were adult (18 years and above), (ii) had diabetes mellitus, (iii) had made at least three previous visits to the same clinic. The data was collected through face-to-face interviews. The structured part of the questionnaire was based on demographic characteristics and the Patient Satisfaction Questionnaire (PSQ-III). We translated the questionnaire into Urdu and pretested it with 25 patients in a similar context. Data storage and analysis were carried out using SPSS (version 22.0). Bivariate analyses and multinomial logistic regression model were used to generate the quantitative findings. Out of the 1164 eligible patients approached for interviews, 1095 patients completed the structured questionnaire and 186 respondents provided qualitative information in comments section. We conducted a thematic content analysis of qualitative responses in order to explain the quantitative findings. Demographic characteristics such as gender, education and occupation were significantly associated with the levels of patient satisfaction. The dimensions of doctor-patient interaction were significantly associated with patient satisfaction: technical expertise (OR = .87; 95% CI = .84-.91), interpersonal aspects (OR = .82; 95% CI = .77-.87), communication (OR = .83; 95% CI = .78-.89), time dimension (OR = .90; 95% CI = .81

    AIMS: Uremia is a prediabetic state, but abnormal glucose metabolism and relative risk factors in non-diabetic chronic kidney disease (CKD) patients are not studied extensively. This study aimed to evaluate prediabetes and contributing factors in patients with CKD. METHODS: We studied the frequency of prediabetes (defined as fasting plasma glucose 100-125 mg/dl and 2-h plasma glucose 140-199 mg/dl) and contributing risk factors in 91 (34 women and 57 men) non-diabetic CKD (GFR prediabetic state. RESULTS: Thirty-eight patients (41.8%), 28 male and 10 female, with mean age of 57.4 ± 17.1 yr, had prediabetes. Among these, 18.7% had impaired fasting glucose, 7.7% impaired glucose tolerance, and 15.4% combined impaired fasting glucose and impaired glucose tolerance. CKD patients with impaired glucose tolerance had more frequently hypertriglyceridemia (85.7% vs. 42.0%, p = 0.001), hypertension (66.6% vs. 31.4%, p = 0.004), and metabolic syndrome according to National Cholesterol Education Program Adult Treatment Panel III (52.3% vs. 25.7%, p = 0.02). Also, mean systolic blood pressure (134.2 ± 13.9 vs. 124.5 ± 20.0, p = 0.004) was higher in CKD patients with impaired glucose tolerance compared to CKD patients with normal glucose. CONCLUSIONS: Prediabetes is a frequent condition in CKD patients. Also, hypertriglyceridemia and hypertension are more prevalent in prediabetic CKD patients than in non-diabetic CKD patients.

    Background. In recent years, plasma base deficit has been used as a marker to determine the status of tissue perfusion in trauma patients and also to predict the outcome of these patients. This study was performed to investigate the effect of plasma base deficit in predicting burn patient outcome. Methods. This prospective cohort study was performed from October 2009 to October 2010 in the acute phase of burn patients who were admitted within 6 h post-injury to Motahari Burn Hospital in Iran. The patients were divided into two groups based on the plasma base deficit in the first 24 h post-injury: group A, in which the mean plasma base deficit was less than or equal to -6 (more negative), and group B, in which the mean plasma base deficit greater than -6. Statistical analysis was performed using SPSS v.16 software. Results. Thirty-eight patients were enrolled in each group. The mean plasma base deficit in group A (-7.76 ± 2.18 mmol) was significantly less than that in group B (-1.19 ± 2.82) mmol (p 0.05) and despite removal of interfering factors, there were significant differences between the systemic inflammatory response syndrome and the multiple organ dysfunction syndrome score and the percentage of sepsis between the two groups (p 0.05). Conclusion. The plasma base deficit can be used as a valuable marker in the resuscitation of burn patients, along with clinical criteria. Physiological indicators (burn percentage, age, and mucosal burns) are not sufficient to predict mortality and morbidity in burn patients, and it is necessary to investigate the role of biochemical markers such as base deficit in determining the final outcome of burn patients.

    Purpose: The aim of this study was to evaluate biologic factors on survival and clinical response after definitive concomitant chemoradiotherapy (CRT) in patients with esophageal squamous cell carcinoma (ESCC). Methods and Materials: TP53 protein hyperexpression (immunochemistry [IHC]) and functional assay (FA) of TP53, measuring the ability of TP53 to transactivate p21 and bax reporter systems, were performed in patients with ESCC treated by CRT. The impact of parameters studied on survival and clinical response to CRT was assessed. Results: Thirty-eight patients with ESCC were included. TP53 alterations were detected in 84.2% of cases with FA. All TP53 mutations abolished the transactivation of p21 and bax reporter systems. After CRT, complete response rate was 55.3%. The median survival of the population was 17.5 months. Serum albumin (p=0.002), weight loss <10% (p=0.005), and response to treatment (p<0.001) were significantly linked with survival. TP53 alteration in FA was not significantly predictive of response to CRT (p=0.132) nor survival (p=0.154). Conclusions: Our results suggest that wild-type TP53 in ESCC could be associated with good response to definitive CRT. However, the small rate of ESCC with wild-type TP53 suggests that systematic determination of TP53 status is not appropriate for the management of the ESCC population

    An experience feedback committee (CREX, Comité de Retour d'EXpérience) is a method which contributes to the management of safety of care in a medical unit. Originally used for security systems of civil aviation, the method has been adapted to health care facilities and successfully implemented in radiotherapy units and in other specialties. We performed a brief review of the literature for studies reporting data on CREX established in hospitals. The review was performed using the main bibliographic databases and Google search results. The CREX is designed to analyse incidents reported by professionals. The method includes monthly meetings of a multi-professional committee that reviews the reported incidents, chooses a priority incident and designates a "pilot" responsible for investigating the incident. The investigation of the incident involves a systemic analysis method and a written synthesis presented at the next meeting of the committee. The committee agrees on actions for improvement that are suggested by the analysis and follows their implementation. Systems for the management of health care, including reporting systems, are organized into three levels: the medical unit, the hospital and the country as a triple loop learning process. The CREX is located in the base level, short loop of risk management and allows direct involvement of care professionals in patient safety. Safety of care has become a priority of health systems. In this context, the CREX can be a useful vehicle for the implementation of a safety culture in medical units. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    The objective of this study was to investigate what treatment options are currently used in Switzerland for Dupuytren's disease. Furthermore, regional preferences and treatment differences based on surgeon experience were analysed. In this survey, an electronic questionnaire was sent to all members of the Swiss Society for Hand Surgery. Participants were asked to indicate their current treatment methods for Dupuytren's disease. In addition, 8 standard patient cases were presented to identify the preferred treatment option. Furthermore, sociodemographic data of the participants were gathered. In total, 70 questionnaires were completed, corresponding to a response rate of 34%. Fasciectomy is performed by 94% of participants, while 59% inject collagenase in certain cases, 40% perform open fasciotomy, and 24% carry out percutaneous needle aponeurotomy if the indication is given. 20% of responders offer one of these techniques, 50% offer 2, 23% offer 3, and 7% offer all 4 treatment techniques. In the case of isolated metacarpophalangeal joint contracture, 51% of participants inject collagenase, whereas fasciectomy is preferred for the treatment of proximal interphalangeal joint contractures or in cases of recurrence. In German-speaking Switzerland, the treatment strategy has changed towards applying collagenase injections in the past 5 years. In this part of the country, 83% of surgeons now use more collagenase than 5 years ago, whereas only 33% of surgeons in French-speaking Switzerland have changed their treatment strategy in favour of collagenase injections (p=0.027). Surgeons with less than 10 years of experience apply more collagenase than their more experienced colleagues (79 vs. 54%, p=0.131). In Switzerland, fasciectomy is the preferred option for treating patients with Dupuytren's disease. In recent years, however, collagenase injection has become more and more popular. More research is needed to define guidelines for the treatment of patients with Dupuytren

    We aimed to evaluate the prevalence of lactose intolerance (LI) in patients with Hashimoto's thyroiditis(HT) and the effects of lactose restriction on thyroid function in these patients. Eighty-three HT patients taking L-thyroxine (LT4) were enrolled, and lactose tolerance tests were performed on all patients. Lactose intolerance was diagnosed in 75.9 % of the patients with HT. Thirty-eight patients with LI were started on a lactose-restricted diet for 8 weeks. Thirty-eight patients with LI (30 euthyroid and 8 with subclinical hypothyroidism), and 12 patients without LI were included in the final analysis. The level of TSH significantly decreased in the euthyroid and subclinical hypothyroid patients with LI [from 2.06 ± 1.02 to 1.51 ±1.1 IU/mL and from 5.45 ± 0.74 to 2.25 ± 1.88 IU/mL,respectively (both P0.05). Lactose intolerance occurs at a high frequency in HT patients. Lactose restriction leads to decreased levels of TSH, and LI should be considered in hypothyroid patients who require increasing LT4 doses,have irregular TSH levels and are resistant to LT4 treatment.

    Several previous studies using univariate analysis have suggested that the pre-anaesthetic train-of-four (TOF) ratio, concentration of anti-acetylcholine receptor (AChR) antibodies and the presence of preoperative generalised muscular involvement are determinants of an increased response to neuromuscular blocking agents (NMBAs) in patients with myasthenia gravis. However, the determinants of the response of patients with myasthenia gravis to rocuronium, which is expected to be used more frequently since the advent of sugammadex, have not been studied. To clarify whether previously suggested determinants of the response to other intermediate-acting NMBAs would also affect the response to rocuronium and to reveal the determinants of the increased response to rocuronium in individual patients with myasthenia gravis using multivariate analysis. Case control study. Kumamoto University Hospital, November 2010 to September 2013. Thirty-eight patients with myasthenia gravis having surgery using a total intravenous anaesthetic technique were investigated. After induction of general anaesthesia, the 95% effective dose (ED95) of rocuronium was calculated using cumulative dose-finding methods. Neuromuscular function was monitored by acceleromyographic assessment of TOF responses of the adductor pollicis muscle to ulnar nerve stimulation. Patients were then divided into the increased response (ED95 rocuronium injection (baseline TOF ratio), concentration of anti-AChR antibodies, Osserman classification and treatment for myasthenia gravis in the two groups were compared. Stepwise logistic regression identified baseline TOF ratio and age of onset of myasthenia gravis as determinants of the increased response to rocuronium in patients with myasthenia gravis [odds ratios (95% confidence interval) of 0.87 (0.77 to 0.98; P = 0.02) and 0.92 (0.86 to 0.99; P = 0.03), respectively]. Multivariate analysis identified baseline TOF ratio and age of disease onset as determinants of

    Full Text Available Objective: Suicide is the 13th leading cause of death worldwide and is influenced by cultural, psychological and social aspects. The aim of this study was to investigate the epidemiology of suicide in Bandar Abbas in 2009.Methods: In a cross-sectional study in 2009, all suicidal patients who were referred to the emergency room (ER of Shahid Mohammadi Hospital of Bandar Abbass were enrolled. Fully trained medical interns of the ER first collected demographic data of the suicidal patients. Then the data, including their reason for attempting suicide, how they attempted suicide, previous suicide attempts, history of substance use, and the size of the family, were collected by direct interviewing the patient. The collected data were analyzed using SPSS-16 software.Results: About 405 patients were enrolled in the study consisting 172 men (44.2% and 226 (55.8% women. Mean age of the participants was 24.29±5.5 years. Most of the suicidal patients were 18 to 26 years old (64.2%. Thirty-eight percent of the women and 62% of the men were addicts. Eleven patients (2.71% died, including eight men and three women. The most prevalent method of suicide leading to death was drug toxicity. Conclusion: Teaching problem-solving skills is an important way to control suicide. Identifying the risk groups, paying closer attention to the 18-26 age group, and moral support of the patients with previous unsuccessful suicide attempts might decrease the suicide rate.

    This study was designed to assess the effect of particular tools on the nutritional status of patients with stroke risk factors; to analyze these risk factors; to construct an assessment table; and to enable nurses to conduct fast and accurate assessment of the nutritional status of patients with stroke. Various nutritional assessment tools were employed to assess the nutritional status of stroke patients [(Nutritional Risk Screening 2002, NRS2002); (mini nutritional assessment, MNA), (subjective global assessment SGA), (malnutrition universal screening, MUST); (body composition, BCA)]. The leading disease-related factors of cerebral apoplexy were observed in patients with malnutrition. And a statistical analysis was conducted. The significant risk factors of cerebral apoplexy in malnourished patients older than 70 years were swallowing dysfunctions, disturbance of consciousness and reliance or half-reliance on feeding practices. The significant risk factors of malnutrition in patients with cerebral apoplexy were the decline in upper limb muscle strength, decline in the performance of various activities, loss of appetite and gastrointestinal symptoms. Disorders that affect the nutritional status of stroke patients can be used as evaluation tools, as described in the evaluation table. The clinical relevance of this study includes the following: to enable the clinical nursing staff to easily assess the patient's nutritional status in a timely manner; to improve compliance with nutritional evaluation; to provide clinical nutrition support to patients with stroke; and to provide a scientific basis for the improvement of the clinical outcomes of patients with cerebral apoplexy.

    An automated ECG-based method may provide diagnostic support in the management of patients with acute coronary syndrome. The Olson method has previously proved to accurately identify the culprit artery in patients with acute coronary occlusion. The Olson method was applied to 360 patients without acute myocardial ischemia and 52 patients with acute coronary occlusion. This study establishes the normal variation of the Olson wall scores in patients without acute myocardial ischemia, which provides the basis for implementation of the Olson method for triage of patients with acute coronary syndrome. All patients with acute occlusion had Olson wall scores above the upper limit of normal. The Olson method can be used for ischemia detection with very high sensitivity. Future studies are needed to explore specificity in patients with non-ischemic ST elevation. Copyright © 2016 Elsevier Inc. All rights reserved.

    M3-specific inhibitors are currently preferred for anticholinergic therapy of OAB. However, not all of the patients profit from this regimen. This might reflect a heterogeneity of the patient group. The aim of this work is to define subgroups of patients with specific alterations of receptor expression and to profile the receptor expression individually. These receptor profiles might be used for the development of evidence-based "tailored" therapies. Detrusor probes from bladder carcinoma patients (BCa, n=9 F, n=7 male) and interstitial cystitis patients (IC, n=9 female) were examined using confocal immunofluorescence and PCR. M2, M3, P2X1-3, and H1-3 mRNAs were demonstrated in detrusor tissue. As revealed by immunofluorescence, the M2 receptor expression was significantly higher in female compared to male BCa tissues. In addition, the M2 receptor was further upregulated in IC vs BCa in female detrusor. IC patients showed specific alterations of their receptor profile. Individual receptor profiles might be used to optimize medicinal therapies.

    PurposeTo explore the efficacy and safety of prophylactic temporary balloon occlusion of the infrarenal abdominal aorta during caesarean for the management of patients with placenta praevia accreta.MethodsTwo hundred and sixty-eight cases of placenta praevia accreta from January 2012 to June 2015 were retrospectively reviewed. Group A included two hundred and thirty patients who underwent prophylactic temporary balloon occlusion of infrarenal abdominal aorta followed by caesarean section. Group B included thirty-eight patients who underwent caesarean without endovascular intervention. The parameters including operating room time, estimated blood loss, blood transfusion volume, PT (prothrombin time) during operation, days in the intensive care unit, and total hospital days were compared between the two groups.ResultsThe operating room time, estimated blood loss, PT, the incidence of hysterectomy, blood transfusion volume, postpartum haemorrhage, and days in intensive care unit were lower in group A than in group B, with statistical significance (P < 0.05). There was no significant difference in the Apgar scores of the neonates and the incidences of thrombosis in lower limbs between the two groups (P > 0.05). No patient in the group with prophylactic temporary balloon occlusion of the infrarenal abdominal aorta was performed hysterectomy, while three patients in group B were performed hysterectomy because of uncontrollable haemorrhage.ConclusionsThe results indicate that prophylactic temporary balloon occlusion of infrarenal abdominal aorta followed by caesarean section is safe and effective to control intraoperative blood loss and greatly decreases the risk of hysterectomy in patients with placenta praevia accreta.

    Hyperfunctioning distant metastasis (HFDM) from differentiated thyroid cancer (DTC) is a rare entity. This study aimed to assess the outcomes of DTC patients presenting with HFDM after total thyroidectomy and radioactive iodine therapy. A total of 5367 DTC patients treated with (131)I after total thyroidectomy were analyzed retrospectively from January 1991 to June 2013. Therapeutic efficacy was evaluated based on changes in serum thyroglobulin (Tg) and anatomical imaging changes in metastatic lesions. The relationships between survival time and several variables were assessed by univariate and multivariate analyses using the Kaplan-Meier method and Cox's proportional hazards model respectively. Thirty-eight patients with HFDM from DTC were diagnosed, including four with hyperthyroidism, four with subclinical hyperthyroidism, and three with subclinical hypothyroidism. The remaining 27 were euthyroid. Of 25 patients with lung metastases, 84% (21/25) showed disappearance or shrinkage of lung nodules; of 24 patients with bone metastases, 66.67% (16/24) exhibited no obvious imaging changes in metastatic bone lesions after (131)I therapy. Serum Tg decreased significantly in 81.58% (31/38) and increased in 18.42% (7/38) after (131)I therapy. The 10-year survival rate of DTC patients with HFDM was 65.79% (25/38). Multivariate analyses identified age at occurrence of distant metastases (thyroid cancer (PTC; p=0.032, NA, and 0.043) as independent predictors of survival. The response of hyperfunctioning lung metastases to (131)I treatment was better than that of non-hyperfunctioning lung metastases in DTC, while hyperfunctioning bone metastases responded similarly compared to non-hyperfunctioning bone metastases. Patients younger than 45 years at occurrence of distant metastases, those with only lung metastases, and patients with PTC had better prognoses.

    Chapple, C.-L.; Broadhead, D.A.

    1995-01-01

    One of the chief sources of uncertainty in the comparison of patient dosimetry data is the influence of patient size on dose. Dose has been shown to relate closely to the equivalent diameter of the patient. This concept has been used to derive a prospective, phantom based method for determining size correction factors for measurements of dose-area product. The derivation of the size correction factor has been demonstrated mathematically, and the appropriate factor determined for a number of different X-ray sets. The use of phantom measurements enables the effect of patient size to be isolated from other factors influencing patient dose. The derived factors agree well with those determined retrospectively from patient dose survey data. Size correction factors have been applied to the results of a large scale patient dose survey, and this approach has been compared with the method of selecting patients according to their weight. For large samples of data, mean dose-area product values are independent of the analysis method used. The chief advantage of using size correction factors is that it allows all patient data to be included in a survey, whereas patient selection has been shown to exclude approximately half of all patients.

Ambulatory blood pressure measurement (ABPM is able to identify patients with masked hypertension (MH underdetected by clinical BP measurement. The benefit of screening for MH in a highrisk population was investigated.Aims: To detect MH in a population with no prior history of hypertension and medically treated for peripheral or coronary arterial disease.Methods: Thirty-eight consecutive patients with peripheral or coronary artery disease documented with arteriography, without a history of hypertension, and with an admission BP < 140/90 mmHg underwent ABPM after discharge. Ambulatory BP ≥ 125/80 mmHg were defined as MH.Results: MH was found in 11 patients (28.9%. The MH group had a mean systolic and diastolic hospitalization BP significantly higher (127 versus 115 mmHg, respectively, P = 0.002 and 76 versus 66 mmHg, P = 0.01, and tended to have a higher admission systolic BP and pulse pressure (127 versus 121 mmHg, respectively, P = 0.07; and 54 versus 46 mmHg, P = 0.06. The first BP measurement on the 24-hour ABPM was significantly higher in the MH group 140 versus 121 mmHg, P = 0.001, for systolic BP and 84 versus 74 mmHg, P = 0.03, for diastolic BP.Conclusions: MH was found in patients with documented and medically treated vascular disease. BP in the prehypertensive range is associated with MH. Systematic screening for MH in this high-risk population requires further investigation.Keywords: blood pressure, monitoring, masked hypertension, vascular disease

    Full Text Available BACKGROUND Porto Alegre is the Brazilian state capital with second highest incidence of tuberculosis (TB and the highest proportion of people infected with human immunodeficiency virus (HIV among patients with TB. Hepatitis C virus (HCV infection increases the risk of anti-TB drug-induced hepatotoxicity, which may result in discontinuation of the therapy. OBJECTIVES The aim of this study was (i to estimate prevalence of HCV and HIV in a group of patients newly diagnosed with active TB in a public reference hospital in Porto Alegre and (ii to compare demographic, behavioural, and clinical characteristics of patients in relation to their HCV infection status. METHODS One hundred and thirty-eight patients with TB were tested for anti-HCV antibody, HCV RNA, and anti-HIV1/2 antibody markers. HCV RNA from real-time polymerase chain reaction (PCR-positive samples was submitted to reverse transcription and PCR amplification. The 5′ non-coding region of the HCV genome was sequenced, and genotypes of HCV isolates were determined. FINDINGS Anti-HCV antibody, HCV RNA, and anti-HIV antibodies were detected in 27 [20%; 95% confidence interval (CI, 13-26%], 17 (12%; 95% CI, 7-18%, and 34 (25%; 95% CI, 17-32% patients, respectively. HCV isolates belonged to genotypes 1 (n = 12 and 3 (n = 4. Some characteristics were significantly more frequent in patients infected with HCV. Among them, non-white individuals, alcoholics, users of illicit drugs, imprisoned individuals, and those with history of previous TB episode were more commonly infected with HCV (p < 0.05. MAIN CONCLUSIONS HCV screening, including detection of anti-HCV antibody and HCV RNA, will be important to improving the management of co-infected patients, given their increased risk of developing TB treatment-related hepatotoxicity.

    Full Text Available One of the most effective methods of infertility treatment is in vitro fertilization (IVF. Effectiveness of the treatment, as well as classification of the data obtained from it, is still an ongoing issue. Classifiers obtained so far are powerful, but even the best ones do not exhibit equal quality concerning possible treatment outcome predictions. Usually, lack of pregnancy is predicted far too often. This creates a constant need for further exploration of this issue. Careful use of different classification methods can, however, help to achieve that goal.

    Full Text Available Background: Ventilator Associated Pneumonia (VAP, developing in mechanically ventilated patients after 48 hours of mechanical ventilation, is the second most common nosocomial infection. Therefore, there is a vital need to study the etiology and risk factors associated with VAP in neonates.Methods: Neonates admitted to neonatal intensive care unit (NICU, over a period of one year and who required mechanical ventilation for more than 48 hours were enrolled consecutively into the study. Semi-quantitative assay of endotracheal aspirate was used for microbiological diagnoses of VAP. 105CFU/ml was taken as the cut off between evidence of pathological infection and colonization. The primary outcome measure was the development of VAP. Secondary outcome measures were length of mechanical ventilation, NICU length of stay, hospital cost, and death.Results: Thirty eight patients were enrolled (58% were boys and 42% were girls. 42% of neonates developed VAP. The most common VAP organisms identified were Acinetobacter baumanni (43%. On multiple regression analysis, duration of mechanical ventilation was associated with VAP (P=0.00. Patients with VAP had greater need for mechanical ventilation (18.7 vs 6 median days, longer NICU length of stay (39 vs 21.5 median days and higher total median hospital costs (79.5 vs 52 million rials than those without VAP. The mortality rate was not different between two groups.Conclusion: In mechanically ventilated neonates, those with VAP had a prolonged need for mechanical ventilation, a longer NICU stay, and a higher hospital costs. Longer mechanical ventilation was associated with an increased risk of developing VAP in these patients. Developing of VAP didn’t increase mortality in patients.

    To test the measure of agreement between use of the Skeletal Maturation Index (SMI) method of Fishman using hand-wrist radiographs and the Cervical Vertebral Maturation Index (CVMI) method for assessing skeletal maturity of the cleft patients. Hand-wrist and lateral cephalometric radiographs of 60 cleft subjects (35 females and 25 males, age range: 7-16 years) were used. Skeletal age was assessed using an adjustment to the SMI method of Fishman to compare with the CVMI method of Hassel and Farman. Agreement between skeletal age assessed by both methods and the intra- and inter-examiner reliability of both methods were tested by weighted kappa analysis. There was good agreement between the two methods with a kappa value of 0.80 (95% CI = 0.66-0.88, p-value <0.001). Reliability of intra- and inter-examiner of both methods was very good with kappa value ranging from 0.91 to 0.99. The CVMI method can be used as an alternative to the SMI method in skeletal age assessment in cleft patients with the benefit of no need of an additional radiograph and avoiding extra-radiation exposure. Comparing the two methods, the present study found better agreement from peak of adolescence onwards.

    Radiation dosages to sensitive organs in full spine radiography have in recent years been a concern of physicians as well as the general public. The spine is the prime target for exposure in scoliosis radiography, though the exposure usually necessitates irradiation of several radio-sensitive organs. In recent studies, various protection techniques have been used including various lead and aluminum filtration systems, altered patient positioning and varied tube-film distances. The purpose of this study was to evaluate the efficiency for radiation dosage reduction of three filtration systems used frequently in the chiropractic profession. The systems tested were the Nolan Multiple X-ray Filters, the Clear-Pb system and the Sportelli Wedge system. These systems were tested in seven configurations varying breast shielding, distance and patient positioning. All systems tested demonstrated significant radiation reductions to organs, especially breast tissue. The Clear-Pb system appeared to be the most effective for all organs except the breast, and the Sportelli Wedge system demonstrated the greatest reduction to breast tissue

    , control of detector uniformity. The test for rotating gamma camera additionally demands controlling precision of rotation and image system resolution. The radioisotope and chemical purity of the radiopharmaceuticals are controlled, too. The process of 99m Tc elution efficacity from 99 Mo-generator is tested and the contents of 99 Mo radioisotope in eluate is measured. The radioisotope diagnosis of brain, heart, thyroid, stomach, liver, kidney and bones as well as lymphoscintigraphy are performed. The procedure used for patient and staff's dose optimisation consists of: 1) control dose measurement performed with dosemeter on the tissue-like phantom including selected radiopharmaceutical of the same radioactivity as the one which will be applied to patient, 2) calculation of the patient dose rate, 3) calculation of the staff dose based on the results of personnel dosemeters (films or TLD), 4) preparation of the Quality Assurance instruction for the staff responsible for patient's safety. Independently of the patient and staff dose optimisation, the Quality Control of gamma camera equipments e.g. SPECT X-Ring Nucline (MEDISO) is checked for uniformity of the image from a radiopharmaceutical sample and center of rotation according to the producer's manual instruction. In addition, special lectures and courses for staff are organized several times per year to ensure a Continuous Professional Development (CPD) in the field of Quality Assurance and Quality Control.

    Full Text Available ABSTRACT Background The Glittre-ADL test (TGlittre is a valid and reliable test for the evaluation of functional capacity and involves multiple physical activities of daily living (PADL, which are known to be troublesome to patients with Chronic Obstructive Pulmonary Disease (COPD. However, it is still unknown if this test is also able to reflect the functional performance of patients with COPD. Objective To investigate whether the TGlittre reflects the functional performance of COPD patients and whether the necessary time to complete the TGlittre and the PADL varies according to disease severity. Method Thirty-eight patients with COPD (age 65, SD=7 years; forced expiratory volume in the first second 41.3, SD=15.2% predicted underwent anthropometric and lung function assessments and were submitted to the TGlittre and PADL measurement. Results TGlittre performance correlated significantly (p<0.05 with PADL variables, such as time sitting (r=0.50, walking (r=-0.46, number of steps taken (r=–0.53, walking movement intensity (r=–0.66, walking energy expenditure (r=-0.50, and total energy expenditure (r=–0.33. TGlittre performance was not significantly different in patients among the Global Initiative for COPD (GOLD spirometric stages, but walking and sitting time were significantly lower and greater, respectively, in severe and very severe patients compared to those with moderate disease (p<0.05. Conclusion The performance on the TGlittre correlates with walking and sitting time and other real life PADL measurements. The severity of the disease is associated with the differences in the level of physical activity in daily life more than in functional capacity.

    Aim: To evaluate the association between liver stiffness measured by acoustic radiation force impulse (ARFI) elastometry and the outcome of antiviral treatment in patients with chronic viral hepatitis B and C. Materials and methods: Thirty-eight patients with chronic viral hepatitis B (n = 16) or hepatitis C (n = 22) underwent liver biopsy and ARFI elastometry of the right hepatic lobe. A follow-up assessment using ARFI was performed a mean of 2.3 years after the baseline evaluation. The patients with favourable outcome were classified in group S and those receiving no treatment, showing no response to treatment, or experiencing a relapse were classified in group N. Results: The 38 patients had an initial mean ARFI value of 1.56 ± 0.62 m/s as compared with 1.54 ± 0.64 m/s in the follow-up evaluation. Group S showed a significant decline in ARFI values (1.55 ± 0.60 m/s versus 1.34 ± 0.47 m/s; p < 0.05) and included 16 (64%) patients with lower shear wave velocities at follow-up. In group N, liver stiffness values showed a slight but not significant increase (1.57 ± 0.70 m/s versus 1.93 ± 0.77 m/s). Conclusion: Changes in liver stiffness during antiviral therapy can be assessed by ARFI reflecting response or no response. ARFI elastometry is an additional, useful tool for the follow-up assessment of treatment outcome in patients with chronic viral hepatitis B or C infection

    The daily use of high level radiation doses to fight against carcinomas has often led to consider radiation protection as a marginal problem, in this area. But the therapeutic advances, by increasing the life time and life quality have made the side effects unacceptable and revealed the appearance of radioinduced carcinomas. So, it is necessary to practice a patient radiation protection. The general principles of radiation protection are applicable to radiotherapy. (justification, optimization and dose limit, planning of the treatment, quality control of installations). (N.C.)

    This study aimed to (1) identify patient-controlled analgesia (PCA) attributes that negatively impact patient satisfaction and ability to control pain while using PCA and (2) obtain data on patient perceptions of new PCA design features. We conducted a prospective survey study of postoperative pain control among patients using a PCA device. The survey was designed to evaluate patient satisfaction with pain control, understanding of PCA, difficulties using PCA, lockout-period management, and evaluation of new PCA design features. A total of 350 eligible patients completed the survey (91%). Patients who had difficulties using PCA were less satisfied (P PCA. Forty-nine percent of patients reported not knowing if they would receive medicine when they pushed the PCA button, and of these, 22% believed that this uncertainty made their pain worse. The majority of patients preferred the proposed PCA design features for easier use, including a light on the button, making it easier to find (57%), and a PCA button that vibrates (55%) or lights up (70%), alerting the patient that the PCA pump is able to deliver more medicine. A majority of patients, irrespective of their satisfaction with PCA, preferred a new PCA design. Certain attributes of current PCA technology may negatively impact patient experience, and modifications could potentially address these concerns and improve patient outcomes.

    Objective The purpose of this study was to present the recent clinical profiles and the real-world management of infective endocarditis (IE). Methods All medical records of patients with IE were reviewed retrospectively for their clinical data, including clinical presentation, laboratory results, blood cultures, echocardiographic findings, treatments and complications. Using the clinical data collected, we calculated the EuroSCORE II, the European risk score for adult cardiac surgery, the Charlson Comorbidity Index as a surrogate of comordibity, and the Katz Index as a surrogate of frailty. Results Thirty-eight patients were identified as having IE (24 men, age: 71.8±13.1 years). Congestive heart failure occurred in 16 patients (42%), stroke in 14 (50%), and systemic embolism in 5 (13%). The EuroSCORE II and Charlson Comorbidity Index were high (7.7±5.8% and 5.5±2.8%, respectively). The Katz Index was fair (5.5±1.4) before the onset but deteriorated to 2.8±2.7 at the time of establishing the diagnosis of IE (p<0.001). Early surgery was performed in 22 cases (61%). In-hospital death occurred in 10 cases (26%). A EuroSCORE II ≥9%, Staphylococcus aureus etiology, and a Charlson Comorbidity Index were suggested as determinants of in-hospital death (hazard ratios: 173.60, 9.31, 1.57, respectively). In contrast, early surgery was suggested as a determinant of the survival (hazard ratio: 0.04). The Charlson Comorbidity Index was also suggested as a determinant for selecting conservative management (odds ratio: 1.40). Conclusion Comorbidity may influence the treatment selection and outcome of elderly patients with IE.

    Quality of life may be assessed using quantitative or qualitative methods. Quantitative methods are commonly used in research settings; however, they may fail to capture the full range of patient experiences and impact on quality of life. Qualitative methods may be used to address this limitation. In this systematic review, we aim to synthesize data from articles utilizing qualitative methods to assess quality of life in dermatology patients. We performed a systematic review search using the MEDLINE, EMBASE, and SCOPUS databases. The search was conducted using the following search criteria: ("Dermatology" [MeSH]) AND ("Quality of Life" [MeSH]), AND ("Qualitative Research" [MeSH]), searching literature spanning from January 1, 1946- October 5, 2016. The systematic review of 15 articles included 533 dermatology patients. Patients expressed frustration over the unpredictability of disease symptoms and having to compensate for the subsequent limitations by altering their daily routines. Patients also reported profound helplessness due to chronic skin disease and social isolation in an effort to hide their disease. Patients noted the patient-provider relationship as a source of support and information exchange, with the goal to form easy to use treatment plans that met both physician and patient expectations. Qualitative assessment of patient quality of life can provide new insights into the patient experience and the impact of their skin disease. Qualitative methodology may capture meaningful information that may be overlooked by quantitative methods, and it should be included in quality of life research.

    (1) To evaluate the operational efficiency of various sampling methods for patient exit interviews; (2) to discuss under what circumstances each method yields an unbiased sample; and (3) to propose a new, operationally efficient, and unbiased sampling method. Literature review, mathematical derivation, and Monte Carlo simulations. Our simulations show that in patient exit interviews it is most operationally efficient if the interviewer, after completing an interview, selects the next patient exiting the clinical consultation. We demonstrate mathematically that this method yields a biased sample: patients who spend a longer time with the clinician are overrepresented. This bias can be removed by selecting the next patient who enters, rather than exits, the consultation room. We show that this sampling method is operationally more efficient than alternative methods (systematic and simple random sampling) in most primary health care settings. Under the assumption that the order in which patients enter the consultation room is unrelated to the length of time spent with the clinician and the interviewer, selecting the next patient entering the consultation room tends to be the operationally most efficient unbiased sampling method for patient exit interviews. © 2016 The Authors.

    Percutaneous endoscopic gastrostomy (PEG) using the direct method is generally indicated for cancer patients. However, there are little available data about peritonitis related to this method. The aim of this retrospective analysis was to assess peritonitis related to PEG using the direct method in patients with cancer. We assessed the prevalence of peritonitis and the relationship between peritonitis and patients' backgrounds, as well as the clinical course after peritonitis. Between December 2008 and December 2011, peritonitis was found in 9 (2.1 %) of 421 patients. Of the 9 patients with peritonitis, 4 had received PEG prior to chemoradiotherapy. Emergency surgical drainage was required in 1 patient, and the remaining 8 recovered with conservative treatment. Peritonitis occurred within 8 days of PEG for 8 of the 9 patients and occurred within 2 days of suture removal for 4 of the 9 patients. Peritonitis related to PEG using the direct method was less frequent for cancer patients. Peritonitis tended to occur within a few days after removal of securing suture and in patients with palliative stage.

    To determine the accuracy of 64 MDCT coronary CTA (CCTA) compared to coronary angiography in low risk patients with stable angina and acute coronary syndrome and determine the number of significant coronary artery stenoses ( 50%) in these patients. Materials and methods. Fifty-five patients underwent CCTA using a 32 MDCT unit with z flying focus allowing the acquisition of 64 slices of 0.6 mm thickness as well as coronary angiography (gold standard). Nine patients were excluded due to prior coronary artery bypass surgery (n=4), insufficient breath hold (n=3), calcium scoring>1000 (n=1) and delay between both examinations over 4 months (n=1). Forty-six patients: 27 males and 19 females were included. CCTA results were compared to coronary angiography per segment and artery with threshold detection of stenoses 50%. The degree of correlation between both examinations was performed using a regression analysis with a Pearson correlation coefficient<0.05 considered significant. The overall accuracy of CCTA was 90%; limitations related to the presence of calcifications, motion artifacts or insufficient vessel opacification. The correlation for all analyzed segments was 96.4%. Thirty-eight of 50 significant stenoses seen on coronary angiography were correctly detected on CCTA. Sensitivity, specificity, PPVC and NPV for detection of stenoses 50% were 76%, 98.3%, 80.3% and 97.7% respectively. Evaluation per segment had a NPV of 96.8% (interventricular and diagonal segments) to 100% (main trunk). Our results for specificity and NPV are similar to reports from the literature. This suggests that CCTA in this clinical setting may replace coronary angiography.

    Background: Pituitary iron overload in patients with transfusion-dependent beta-thalassemia may lead to delayed puberty. Magnetic resonance imaging (MRI) has the potential to estimate tissue iron concentration by detecting its paramagnetic effect and hypophyseal damage by measuring its dimensions indirectly. Purpose: To investigate the association of pituitary MRI findings and pubertal status in thalassemic patients as well as to demonstrate any priority in appearance of them. Material and Methods: Twenty-seven beta-thalassemic patients, aged 15-25 years, were divided into 13 with (group A) and 14 without hypogonadism (group B), matched by age, gender, duration of transfusion, and chelation therapy. Thirty-eight age- and sex-adjusted healthy control individuals were also included (group C). All participants underwent pituitary MRI using a 1.5T unit. Pituitary-to-fat signal intensity ratios (SIR) were calculated from coronal T2-weighted images. Estimated pituitary volumes were measured using pituitary height, width, and length on T1-weighted images. Results: The mean values of pituitary-to-fat SIRs were significantly lower in group A as compared with group B (P <0.001), and likewise group B had statistically lower values than group C (P=0.03). The pituitary height and volume were significantly decreased in group A compared to group B (P = 0.006 and P = 0.002, respectively), while these differences did not demonstrate statistically significance between groups B and C. Conclusion: Pituitary MRI findings such as signal intensity reduction and decrease in volume can be useful markers in estimating pituitary dysfunction in beta-thalassemic patients. Compared to healthy controls, lower values of pituitary-to-fat SIRs in thalassemic patients experiencing normal puberty, without marked decrease in volume, indicate that signal reduction may precede volume loss and could be expected first on MRI

    Epstein Barr virus (EBV) plays a causal role in some diseases, including infectious mononucleosis, lymphoproliferative diseases and nasopharyngeal carcinoma. Detection of EBV infection has been shown to be a useful tool for diagnosing EBV-related diseases. In the present study, we compared the performance of molecular tests, including fluorescence in situ hybridization (FISH) and EBV real-time PCR, to those of serological assays for the detection of EBV infection. Thirty-eight patients with infectious mononucleosis (IM) were enrolled, of whom 31 were diagnosed with a mild type, and seven were diagnosed with IM with haemophagocytic lymphohistiocytosis and chronic active EBV infection. Twenty healthy controls were involved in the study. The atypical lymphocytes in peripheral blood were detected under a microscope and the percentage of positive cells was calculated. EBV DNA load in peripheral blood was detected using real-time PCR. The FISH assay was developed to detect the EBV genome from peripheral blood mononuclear cells (PBMC). Other diagnosis methods including the heterophil agglutination (HA) test and EBV-VCA-IgM test, to detect EBV were also compared. SPSS17.0 was used for statistical analysis. In all, 5-41% atypical lymphocytes were found among the PBMC in mild IM patients, whereas 8-51% atypical lymphocytes were found in IM patients with haemophagocytic lymphohistiocytosis and chronic active EBV infection patients. There was no significant difference in the ratios of atypical lymphoma between patients of the different types. We observed that 71.2% of mild IM patients and 85.7% of IM patients with haemophagocytic lymphohistiocytosis and chronic active EBV infection patients were positive for EBV-VCA-IgM. EBV-VCA-IgM was negative in all healthy control subjects. In addition, 67.1% of mild IM patients tested heterophile antibody positive, whereas 71.4% of IM patients with haemophagocytic lymphohistiocytosis and chronic active EBV infection tested positive.

    In recent years, malnutrition in patients with liver cirrhosis has been taken more and more seriously in clinical physicians, and patients' nutritional status is closely associated with prognosis. At present, there are many methods for the evaluation of nutritional status in patients with liver cirrhosis, but there are still no unified standards. This article reviews the common evaluation indices and methods used in clinical practice in China and foreign countries, in order to provide a basis for accurately evaluating nutritional status and guiding nutritional therapy in patients with liver cirrhosis.

    Metaiodobenzylguanidine (MIBG) has been used for the detection and treatment of neuroectodermal tumors, including neuroblastoma. We report our experience with 131 I-MIBG used diagnostically in neuroblastoma patients with relapse. Thirty-eight studies were performed in 26 patients. There were 24 children (range 3 months-14 years) and two adults. While the study was found to be both sensitive and specific for the presence of disease, there are instances of discordance. False-negative studies were found with a markedly anaplastic tumor and with two mature ganglioneuromas. A bone lesion was negative with 131 I-MIBG, but positive on bone scan. A biopsy confirmed the presence of neuroblastoma. Caution should be exercised when scanning pretreated patients, and perhaps with newly diagnosed patients as well

    Purpose: Proton radiotherapy allows radiation treatment delivery with high dose gradients. The nature of such dose distributions increases the influence of patient positioning uncertainties on their fidelity when compared to photon radiotherapy. The present work quantitatively analyzes the influence of setup uncertainties on proton range and dose distributions. Methods: Thirty-eight clinical passive scattering treatment fields for small lesions in the head were studied. Dose distributions for shifted and rotated patient positions were Monte Carlo-simulated. Proton range uncertainties at the 50%- and 90%-dose falloff position were calculated considering 18 arbitrary combinations of maximal patient position shifts and rotations for two patient positioning methods. Normal tissue complication probabilities (NTCPs), equivalent uniform doses (EUDs), and tumor control probabilities (TCPs) were studied for organs at risk (OARs) and target volumes of eight patients. Results: The authors identified a median 1σ proton range uncertainty at the 50%-dose falloff of 2.8 mm for anatomy-based patient positioning and 1.6 mm for fiducial-based patient positioning as well as 7.2 and 5.8 mm for the 90%-dose falloff position, respectively. These range uncertainties were correlated to heterogeneity indices (HIs) calculated for each treatment field (38% < R{sup 2} < 50%). A NTCP increase of more than 10% (absolute) was observed for less than 2.9% (anatomy-based positioning) and 1.2% (fiducial-based positioning) of the studied OARs and patient shifts. For target volumes TCP decreases by more than 10% (absolute) occurred in less than 2.2% of the considered treatment scenarios for anatomy-based patient positioning and were nonexistent for fiducial-based patient positioning. EUD changes for target volumes were up to 35% (anatomy-based positioning) and 16% (fiducial-based positioning). Conclusions: The influence of patient positioning uncertainties on proton range in therapy of small lesions

    The purpose of this study was to examine whether two different physiotherapy regimes caused any differences in outcome in the rehabilitation after stroke. We examined 240 patients with stroke. Examination was carried out at the Rehabilitation Center of Kaunas Second Clinical Hospital. Patients were divided into 2 groups: Bobath method was applied to the first (I) group (n=147), motor relearning program (MRP) method was applied to the second (II) group (n=93). In every group of patients we established samples according to sex, age, hospitalization to rehab unit as occurrence of CVA degree of disorder (hemiplegia, hemiparesis). The mobility of patients was evaluated according to European Federation for Research in Rehabilitation (EFRR) scale. Activities of daily living were evaluated by Barthel index. Analyzed groups were evaluated before physical therapy. When preliminary analysis was carried out it proved no statically reliable differences between analyzed groups (reliability 95%). The same statistical analysis was carried out after physical therapy. The results of differences between patient groups were compared using chi(2) method. Bobath method was applied working with the first group of patients. The aim of the method is to improve quality of the affected body side's movements in order to keep both sides working as harmoniously as possible. While applying this method at work, physical therapist guides patient's body on key-points, stimulating normal postural reactions, and training normal movement pattern. MRP method was used while working with the second group patients. This method is based on movement science, biomechanics and training of functional movement. Program is based on idea that movement pattern shouldn't be trained; it must be relearned. CONCLUSION. This study indicates that physiotherapy with task-oriented strategies represented by MRP, is preferable to physiotherapy with facilitation/inhibition strategies, such the Bobath programme, in the

    A robust, reproducible, and high throughput method was developed for the relative quantitative analysis of glycoprotein abundances in human serum. Instead of quantifying glycoproteins by glycopeptides in conventional quantitative glycoproteomics, glycoproteins were quantified by nonglycosylated peptides derived from the glycoprotein digest, which consists of the capture of glycoproteins in serum samples and the release of nonglycopeptides by trypsin digestion of captured glycoproteins followed by two-dimensional liquid chromatography-tandem MS analysis of released peptides. Protein quantification was achieved by comparing the spectrum counts of identified nonglycosylated peptides of glycoproteins between different samples. This method was demonstrated to have almost the same specificity and sensitivity in glycoproteins quantification as capture at glycopeptides level. The differential abundance of proteins present at as low as nanogram per milliliter levels was quantified with high confidence. The established method was applied to the analysis of human serum samples from healthy people and patients with hepatocellular carcinoma (HCC) to screen differential glycoproteins in HCC. Thirty eight glycoproteins were found with substantial concentration changes between normal and HCC serum samples, including α-fetoprotein, the only clinically used marker for HCC diagnosis. The abundance changes of three glycoproteins, i.e. galectin-3 binding protein, insulin-like growth factor binding protein 3, and thrombospondin 1, which were associated with the development of HCC, were further confirmed by enzyme-linked immunosorbent assay. In conclusion, the developed method was an effective approach to quantitatively analyze glycoproteins in human serum and could be further applied in the biomarker discovery for HCC and other cancers.

    Fifty five patients suffering from blunt chest trauma were studied to assess the diagnosis of myocardial contusion using thallium 201 myocardial scintigraphy. Thirty-eight patients had consistent scintigraphic defects and were considered to have a myocardial contusion. All patients with scintigraphic defects had paroxysmal arrhythmias and/or ECG abnormalities. Of 38 patients, 32 had localized ST-T segment abnormalities; 29, ST-T segment abnormalities suggesting involvement of the same cardiac area as scintigraphic defects; 21, echocardiographic abnormalities. Sixteen patients had segmental hypokinesia involving the same cardiac area as the scintigraphic defects. Fifteen patients had clinical signs suggestive of myocardial contusion and scintigraphic defects. Almost 70 percent of patients with blunt chest trauma had scintigraphic defects related to areas of myocardial contusion. When thallium 201 myocardial scintigraphy directly showed myocardial lesion, two-dimensional echocardiography and standard ECG detected related functional consequences of cardiac trauma

    Full Text Available Isabelle Scholl, Jördis M Zill, Martin Härter, Jörg Dirmaier Department of Medical Psychology, University Medical Center Hamburg-Eppendorf, Hamburg, Germany Background: The concept of patient-centeredness has gained in importance over recent decades, including its growing importance on a health policy level. However, many different definitions and frameworks exist. This renders both research and implementation into clinical practice difficult. This study aimed at assessing how German researchers conceptualize patient-centeredness, how they translate the German equivalent into English, and what they consider the most important references on the topic. Methods: All researchers within a German research priority program on patient-centeredness were invited to participate in an online survey with open questions. The data regarding the definitions of patient-centeredness were analyzed using the method of conventional content analysis. Descriptive statistics were used to analyze the responses on translations and references. Results: Thirty-eight (28% of 136 invited researchers participated in the study. The definitions given by the participants could be classified into ten categories: patient as a unique person, involvement in decision-making, patient information, essential characteristics of the physician, biopsychosocial perspective, patient empowerment, individualized services, patient-reported outcomes, involvement in health policy and coordination and teamwork. The results for the translation of the German word “Patientenorientierung” into English indicate that uncertainty regarding the appropriate English terminology exists. All participants provided a different reference on patient-centeredness that was important to them. Conclusion: The results show a certain degree of “shared meaning” regarding the concept of patient-centeredness. However, they also indicate a considerable amount of “surplus meaning”, which can be seen as an

    2014-06-01

    To describe how patients with major depression in psychiatric outpatient care use the portfolio method and whether the method helps the patients to understand their depression. Major depressive disorder is an increasing problem in society. Learning about one's depression has been demonstrated to be important for recovery. If the goal is better understanding and management of depression, learning must proceed on the patient's own terms, based on the patient's previous understanding of their depression. Learning must be aligned with patient needs if it is to result in meaningful and useful understanding. Each patient's portfolio consisted of a binder. Inside the binder, there was a register with predetermined flaps and questions. The patients were asked to work with the questions in the sections that built the content in the portfolio. Individual interviews with patients (n = 5) suffering from major depression according to Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV) (American Psychiatric Association 1994) were repeatedly conducted between April 2008 and August 2009 in two psychiatric outpatient clinics in western Sweden. Data were analysed using latent content analysis. The results showed that the portfolio was used by patients as a management strategy for processing and analysis of their situation and that a portfolio's structure affects its usability. The patients use the portfolio for reflection on and confirmation of their progress, to create structure in their situation, as a management strategy for remembering situations and providing reminders of upcoming activities. Using a clearly structured care portfolio can enable participation and patient learning and help patients understand their depression. The portfolio method could provide a tool in psychiatric nursing that may facilitate patient understanding and increase self-efficacy. © 2013 John Wiley & Sons Ltd.

    The purpose of this study was to evaluate the efficacy of ball tip method for thoracic pedicle screw placements in idiopathic scoliosis patients. 24 patients with adolescent idiopathic scoliosis were included in this study. Conventional method was performed in 12 patients. Ball tip method was performed in 12 patients. Accuracy of the pedicle screw placement was evaluated based on the postoperative CT. In the ball tip method, a probe which was consisted of ball tip with flexible shaft was used. After removing of cortical bone at a starting point, the probe was inserted manually or sometimes with gently tapping by hammer. During the maneuver, the probe will gradually progress into cancellous bone in the pedicle, without perforating cortical bone in the pedicle. Following expansion of the hole by a rigid gear shift probe, screw was placed in the pedicle. 65.1% of screws were located within pedicle in the conventional group and 86.5% in the ball tip group. 5.3% of screws were located out of pedicle within 2 mm in the conventional group and 8.2% in the ball tip group. 15.8% of screws were located out of pedicle beyond 2 mm and 1.8% in the ball tip group. The ball tip method enhanced the accuracy of thoracic pedicle screw placements in adolescent idiopathic scoliosis patients. The ball tip method may be effective for accurate pedicle screw placement in patients with adolescent idiopathic scoliosis. (author)

    Quantitative analysis of intracranial EEG is a promising tool to assist clinicians in the planning of resective brain surgery in patients suffering from pharmacoresistant epilepsies. Quantifying the accuracy of such tools, however, is nontrivial as a ground truth to verify predictions about hypothetical resections is missing. As one possibility to address this, we use customized hypotheses tests to examine the agreement of the methods on a common set of patients. One method uses machine learning techniques to enable the predictive modeling of EEG time series. The other estimates nonlinear interrelation between EEG channels. Both methods were independently shown to distinguish patients with excellent post-surgical outcome (Engel class I) from those without improvement (Engel class IV) when assessing the electrodes associated with the tissue that was actually resected during brain surgery. Using the AND and OR conjunction of both methods we evaluate the performance gain that can be expected when combining them. Both methods' assessments correlate strongly positively with the similarity between a hypothetical resection and the corresponding actual resection in class I patients. Moreover, the Spearman rank correlation between the methods' patient rankings is significantly positive. To our best knowledge, this is the first study comparing surgery target assessments from fundamentally differing techniques. Although conceptually completely independent, there is a relation between the predictions obtained from both methods. Their broad consensus supports their application in clinical practice to provide physicians additional information in the process of presurgical evaluation. Copyright © 2018 Elsevier B.V.

    To evaluate the utility of ultrasonography (US) as a guide in deciding drainage methods and as a prognostic factor in the prediction of pleural fibrosis, and to compare the effects of drainage methods in patients with tuberculous pleural effusions. In 51 patients with tuberculous pleural effusion, US patterns of pleural effusion were classified according to degree of septa into three groups, as follows : anechoic (n=5), linear septa (n=15), and honeycomb septa (n=31). US-guided drainage methods, including thoracentesis (n=17), percutaneous catheter insertion (n=12), catheter insertion with urokinase instillation (n=22) were employed. Therapeutic effects were evaluated with follow-up chest radiographs after 3 and 6 months. Three months after the procedure, 43 of 51 effusions had drained effectively. US guided drainage failed in eight patients including two of six with linear septated effusion treated with thoracentesis, four of seven with honeycomb septated effusion treated with thoracentesis, and two of six with honeycomb septated effusion treated with catheter drainage. There was no drainage failure in patients with anechoic effusions and in patients with urokinase instillation. Late effects were assessed in 39 patients after 6 months. Follow-up radiographs available in 39 patients demonstrated pleural fibrosis with intercostal space narrowing in 7 patients with honeycomb septated effusion, 3 patients with linear septated effusion, and none of the patients with anechoic effusions. The pattern of septa seen on US could be a useful factor for determining drainage methods and predicting late results in tuberculous pleural effusion. Percutaneous catheter drainage with urokinase instillation was a good drainage modality for patients with septated pleural effusions. Pleural fibrosis is more frequently induced by septated pleural effusion than by anechoic pleural effusion

    2015-01-01

    There is a broad consensus on the importance for health professionals to support co-active patients. However, in practice, very few "patient care partnership" approaches have been developed. We hypothesized that the lack of investment in supporting patient care partnerships is due to the lack of interest in the skills needed by caregivers to provide such support. This paper intends to address thisgap. The patient care partnership method is studied, adapted and developed from existing models. It complements, harmonizes and integrates various schools of thought arising from the need to place the patient at the center of care and life in general. The patient care partnership method includes 7 stages during which the professional accompanies the patient through the process of care. The methodological approach for training professionals is designed to ensure that professionals experience the change as well as its difficulties of the change they expect from the patient in the care relationship. This method now needs to be validated by the experience of other professionals in order define the limits of application and to allow further development.

    There have been very few studies focusing on what form of communication patients would find acceptable from a clinic. This study looks at the differences in preferences for various partner notification methods when the respondents were index patients compared with when they had to be contacted because a partner had a sexually transmitted infection (STI). There were 2544 respondents. When the clinic had to notify partners, respondents were more likely to report the method as good when a partner had an STI and they were being contacted compared with when the respondents had an infection and the partner was being contacted. The opposite was true for patient referral partner notification. Therefore, there are variations in the preferences of respondents for partner notification method, which depend on whether they see themselves as index patients or contacts.

    Background : This study investigated patients' understanding of the role of music in coping and in influencing their well-being. Methods : A qualitative study was conducted based on semi-structured interviews with 17 cancer patients. Participants were chosen from a group of patients who had listened to or played music as a means of coping with their illness. Results : The study shows the importance of considering the roles that different kinds of music play in coping with cancer. The music of nature, healing music, religious music and cheerful music each have different benefits for patients. Conclusions : A patient's situation and his or her individual characteristics determine the types of music that can act as a useful or harmful coping strategy. Therefore, it is essential to investigate the types of individual characteristics that can make listening to different kinds of music a helpful or harmful coping method.

    The process of care of patients with diabetes is complex; however, GPs are playing a greater role in its management. Despite the research evidence, the quality of care of patients with diabetes is variable. In order to improve care, information is required on the obstacles faced by practices in improving care. Qualitative and quantitative methods can be used for formation of hypotheses and the development of survey procedures. However, to date few examples exist in general practice research on the use of multiple methods using both quantitative and qualitative techniques for hypothesis generation. We aimed to determine information on all factors that may be associated with delivery of care to patients with diabetes. Factors for consideration on delivery of diabetes care were generated by multiple qualitative methods including brainstorming with health professionals and patients, a focus group and interviews with key informants which included GPs and practice nurses. Audit data showing variations in care of patients with diabetes were used to stimulate the brainstorming session. A systematic literature search focusing on quality of care of patients with diabetes in primary care was also conducted. Fifty-four potential factors were identified by multiple methods. Twenty (37.0%) were practice-related factors, 14 (25.9%) were patient-related factors and 20 (37.0%) were organizational factors. A combination of brainstorming and the literature review identified 51 (94.4%) factors. Patients did not identify factors in addition to those identified by other methods. The complexity of delivery of care to patients with diabetes is reflected in the large number of potential factors identified in this study. This study shows the feasibility of using multiple methods for hypothesis generation. Each evaluation method provided unique data which could not otherwise be easily obtained. This study highlights a way of combining various traditional methods in an attempt to overcome the

    Background Patient portals have yet to achieve their full potential for enhancing health communication and improving health outcomes. Although the Patient Protection and Affordable Care Act in the United States mandates the utilization of patient portals, and usage continues to rise, their impact has not been as profound as anticipated. Objective The objective of our case study was to evaluate how well portals convey information to patients. To demonstrate how multiple methodologies could be used to evaluate and improve the design of patient-centered portals, we conducted an in-depth evaluation of an exemplar patient-centered portal designed to promote preventive care to consumers. Methods We used 31 critical incident patient interviews, 2 clinician focus groups, and a thematic content analysis to understand patients’ and clinicians’ perspectives, as well as theoretical understandings of the portal’s use. Results We gathered over 140 critical incidents, 71.8% (102/142) negative and 28.2% (40/142) positive. Positive incident categories were (1) instant medical information access, (2) clear health information, and (3) patient vigilance. Negative incident categories were (1) standardized content, (2) desire for direct communication, (3) website functionality, and (4) difficulty interpreting laboratory data. Thematic analysis of the portal’s immediacy resulted in high scores in the attributes enhances understanding (18/23, 78%), personalization (18/24, 75%), and motivates behavior (17/24, 71%), but low levels of interactivity (7/24, 29%) and engagement (2/24, 8%). Two overarching themes emerged to guide portal refinements: (1) communication can be improved with directness and interactivity and (2) perceived personalization must be greater to engage patients. Conclusions Results suggest that simple modifications, such as increased interactivity and personalized messages, can make portals customized, robust, easily accessible, and trusted information sources

    This study investigated the relationship between psychological well-being and different voice rehabilitation methods in total laryngectomy patients. The study enrolled 96 patients who underwent total laryngectomy. The patients were divided into three groups according to the voice rehabilitation method used: esophageal speech (24 patients); a tracheoesophageal fistula and Provox 2 voice prosthesis (57 patients); or an electrolarynx (15 patients). The participants were asked to complete the Turkish version of the Voice Handicap Index-10 (VHI-10) to assess voice problems. They were also asked to complete the Turkish version of the Perceived Stress Scale (PSS), and the Hospital Anxiety and Depression Scale (HADS). The test scores of the three groups were compared statistically. Patients who used esophageal speech had a mean VHI-10 score of 10.25 ± 3.22 versus 19.42 ± 5.56 and 17.60 ± 1.92 for the tracheoesophageal fistula and Provox 2 and electrolarynx groups respectively, reflecting better perception of their voice. They also had a PSS score of 11.38 ± 3.92, indicating that they felt less stressed in comparison with the tracheoesophageal fistula and Provox 2 and electrolarynx groups, which scored 18.84 ± 5.50 and 16.20 ± 3.49 respectively. The HADS scores of the groups were not different, indicating that the patients' anxiety and depression status did not vary. Patients who used esophageal speech perceived less stress and were less handicapped by their voice.

    Full Text Available The number of patients with knee osteoarthritis has increased in tandem with population aging. Consequently, the number of knee arthroplasties has also risen. The postoperative pain is the biggest challenge faced by patients soon after knee arthroplasty; therefore, this study is among different methods for post-knee arthroplasty pain control. A prospective longitudinal research design was employed; 177 adult patients who proposed for primary knee arthroplasty were enrolled and recruited. The patients were divided into conventional Group 1 (n=120 and patient-controlled analgesia (PCA Group 2 (n=57 according to the treatment methods they received. All patients experience the highest pain level on the day of their surgery; women complained of higher pain levels than men did, while the PCA group had lower postoperative pain. Meanwhile, patients with general anesthesia experienced more pain than those with spinal anesthesia in postoperative period. Patients with a higher postoperative pain index have a smaller optimal knee flexion angle. The PCA group had lower postoperative pain; all patients experienced the highest pain level on the day of their surgery. The results of this study could serve as a reference for nurses where PCA ensures a better postoperative pain control and therefore facilitates recovery and improves the quality of nursing.

    There is a demand for a flexible and individually tailored patient education to meet patients' specific needs and priorities, but this area has seldom been studied in patients with spondyloarthritis (SpA), a family of inflammatory rheumatic diseases. The aim of the present study was to identify needs and priorities in patient education in patients with SpA. A second aim was to investigate patients' experiences and preferences of receiving patient education. Data collection included a questionnaire survey with the Educational Needs Assessment Tool (ENAT) and interviews, using a mixed-methods design. Patients were identified through a specialist clinic register. Descriptive data are presented as mean with standard deviation, or frequencies. Chi-square test and independent-samples t-test were used for group comparisons. A manifest qualitative conventional content analysis was conducted to explore patients' experiences and needs in patient education, based on two focus groups (n = 6) and five individual interviews. Almost half (43%) of the 183 SpA patients had educational needs, particularly regarding aspects of self-help, feelings, and the disease process. More educational needs were reported by women and in patients with higher disease activity, while duration of disease did not affect the needs. The qualitative analysis highlighted the importance of obtaining a guiding, reliable, and easily available patient education for management of SpA. Individual contacts with healthcare professionals were of importance, but newer media were also requested. There are considerable educational needs in patients with SpA, and education concerning self-help, feelings, and the diseases process were raised as important issues. Healthcare professionals need to consider the importance of presenting varied formats of education based on the experiences and preferences of patients with SpA.

  13. Effects of auditing patient safety in hospital care: design of a mixed-method evaluation

    2013-01-01

    Background Auditing of patient safety aims at early detection of risks of adverse events and is intended to encourage the continuous improvement of patient safety. The auditing should be an independent, objective assurance and consulting system. Auditing helps an organisation accomplish its objectives by bringing a systematic, disciplined approach to evaluating and improving the effectiveness of risk management, control, and governance. Audits are broadly conducted in hospitals, but little is known about their effects on the behaviour of healthcare professionals and patient safety outcomes. This study was initiated to evaluate the effects of patient safety auditing in hospital care and to explore the processes and mechanisms underlying these effects. Methods and design Our study aims to evaluate an audit system to monitor and improve patient safety in a hospital setting. We are using a mixed-method evaluation with a before-and-after study design in eight departments of one university hospital in the period October 2011–July 2014. We measure several outcomes 3 months before the audit and 15 months after the audit. The primary outcomes are adverse events and complications. The secondary outcomes are experiences of patients, the standardised mortality ratio, prolonged hospital stay, patient safety culture, and team climate. We use medical record reviews, questionnaires, hospital administrative data, and observations to assess the outcomes. A process evaluation will be used to find out which components of internal auditing determine the effects. Discussion We report a study protocol of an effect and process evaluation to determine whether auditing improves patient safety in hospital care. Because auditing is a complex intervention targeted on several levels, we are using a combination of methods to collect qualitative and quantitative data about patient safety at the patient, professional, and department levels. This study is relevant for hospitals that want to

    Elevated blood pressure is a major risk factor for cardiovascular disease and stroke but patients often discount recommended behavioral changes and prescribed medications. While effective interventions to promote adherence have been developed, cost-effectiveness from the patient's perspective, has not been well studied. The valuation of patient time and out of pocket expenses should be included while performing cost effectiveness evaluation. The Achieve BP study uses the contingent valuation method to assess willingness to accept (WTA) and willingness to pay (WTP) among patients with a history of uncontrolled blood pressure discharged from an urban emergency department and enrolled in a larger randomized controlled trial. WTA and WTP were assessed by asking patients a series of questions about time and travel costs and time value related to their study participation. A survey was conducted during the final study visit with patients to investigate the effectiveness of a kiosk-based educational intervention on blood pressure control. All study patients, regardless of study arm, received the same clinical protocol of commonly prescribed antihypertensive medication and met with research clinicians four times as part of the study procedures. Thirty-eight patients were offered the opportunity to participate in the cost-effectiveness study and all completed the survey. Statistical comparisons revealed these 38 patients were similar in representation to the entire RCT study population. All 38 (100.0%) were African-American, with an average age of 49.1 years; 55.3% were male, 21.1% were married, 78.9% had a high school or higher education, and 44.7% were working. 55.9% did not have a primary care provider and 50.0% did not have health insurance. Time price linear regression analysis was performed to estimate predictors of WTA and WTP. WTP and WTA may generate different results, and the elasticities were proportional to the estimated coefficients, with WTP about twice as

    Full Text Available BackgroundContinuous glucose monitoring (CGM is reported to be a useful technique, but difficult or inconvenient for some patients and institutions. We are developing a glucose area under the curve (AUC monitoring system without blood sampling using a minimally invasive interstitial fluid extraction technology (MIET. Here we evaluated the accuracy of interstitial fluid glucose (IG AUC measured by MIET in patients with diabetes for an extended time interval and the potency of detecting hyperglycemia using CGM data as a reference.MethodsThirty-eight inpatients with diabetes undergoing CGM were enrolled. MIET comprised a pretreatment step using a plastic microneedle array and glucose accumulation step with a hydrogel patch, which was placed on two sites from 9:00 AM to 5:00 PM or from 10:00 PM to 6:00 AM. IG AUC was calculated by accumulated glucose extracted by hydrogel patches using sodium ion as standard. ResultsA significant correlation was observed between the predicted AUC by MIET and CGM in daytime (r=0.76 and nighttime (r=0.82. The optimal cutoff for the IG AUC value of MIET to predict hyperglycemia over 200 mg/dL measured by CGM for 8 hours was 1,067.3 mg·hr/dL with 88.2% sensitivity and 81.5% specificity.ConclusionWe showed that 8-hour IG AUC levels using MIET were valuable in estimating the blood glucose AUC without blood sampling. The results also supported the concept of using this technique for evaluating glucose excursion and for screening hyperglycemia during 8 hours in patients with diabetes at any time of day.

    Introduction Disease activity in patients with rheumatoid arthritis (RA) is associated with increased cardiovascular morbidity and mortality, of which N-terminal pro-brain natriuretic peptide (NT-proBNP) is a predictor. Our objective was to examine the cross-sectional and longitudinal associations between markers of inflammation, measures of RA disease activity, medication used in the treatment of RA, and NT-proBNP levels (dependent variable). Methods Two hundred thirty-eight patients with RA of less than 4 years in duration were followed longitudinally with three comprehensive assessments of clinical and radiographic data over a 10-year period. Serum samples were frozen and later batch-analyzed for NT-proBNP levels and other biomarkers. Bivariate, multivariate, and repeated analyses were performed. Results C-reactive protein (CRP) levels at baseline were cross-sectionally associated with NT-proBNP levels after adjustment for age and gender (r2 adjusted = 0.23; P < 0.05). At the 10-year follow-up, risk factors for cardiovascular disease were recorded. Duration of RA and CRP levels were independently associated with NT-proBNP in the final model that was adjusted for gender, age, and creatinine levels (r2 adjusted = 0.38; P < 0.001). In the longitudinal analyses, which adjusted for age, gender, and time of follow-up, we found that repeated measures of CRP predicted NT-proBNP levels (P < 0.001). Conclusion CRP levels are linearly associated with levels of NT-proBNP in cross-sectional and longitudinal analyses of patients with RA. The independent associations of NT-proBNP levels and markers of disease activity with clinical cardiovascular endpoints need to be further investigated. PMID:18573197

    Full Text Available Fibromyalgia can limit activities of daily living (ADLs performance and has a negative impact on the quality of life of these patients. The objective of this study was to evaluate the association between direct and indirect methods for the assessment of functional capacity and their relationship with some features of fibromyalgia. Thirty-eight women with a diagnosis of fibromyalgia participated in the study. Functional capacity was assessed by the Health Assessment Questionnaire (HAQ, distance in the six-minute walk test (6MWT, and handgrip strength (HGS. Pain was rated on a visual analog scale. The Fibromyalgia Impact Questionnaire (FIQ was applied to assess the impact on quality of life. Body mass index and waist circumference were also evaluated. Pearson’s correlation test was used for parametric data and Spearman’s correlation test for nonparametric data. Multiple regressions were also performed. Pain intensity was high in the patients (median: 9.5. The 6MWT distance was correlated with HAQ score (r=-0.55, p<0.01 and HGS (r=0.34, p<0.01. Pain was correlated with HGS (r=-0.41, p<0.01, HAQ score (r=0.62, p<0.01, and FIQ (r =0.66, p<0.01. Pain intensity explained 40% of the variation in HAQ scores. This variation increased to 60% after inclusion of 6MWT distance. In conclusion, pain seems to compromise HGS, ADLs and quality of life in women with fibromyalgia. The lower performance in the 6MWT might be explained by high body mass index. Taking into account pain, the HAQ seems to be an appropriate tool for the assessment of functional capacity in women with fibromyalgia.

    An accurate determination of body temperature in critically ill patients is a fundamental requirement for initiating the proper process of diagnosis, and also therapeutic actions; therefore, the aim of the study was to assess the accuracy and precision of four noninvasive peripheral methods of temperature measurement compared to the central nasopharyngeal measurement. In this observational prospective study, 237 patients were recruited from the intensive care unit of Imam Ali Hospital of Kermanshah. The patients' body temperatures were measured by four peripheral methods; oral, axillary, tympanic, and forehead along with a standard central nasopharyngeal measurement. After data collection, the results were analyzed by paired t-test, kappa coefficient, receiver operating characteristic curve, and using Statistical Package for the Social Sciences, version 19, software. There was a significant meaningful correlation between all the peripheral methods when compared with the central measurement (Ptemperatures of right and left tympanic membranes and the standard central nasopharyngeal measurement (88%). Paired t-test demonstrated an acceptable precision with forehead (P=0.132), left (P=0.18) and right (P=0.318) tympanic membranes, oral (P=1.00), and axillary (P=1.00) methods. Sensitivity and specificity of both the left and right tympanic membranes were more than for other methods. The tympanic and forehead methods had the highest and lowest accuracy for measuring body temperature, respectively. It is recommended to use the tympanic method (right and left) for assessing a patient's body temperature in the intensive care units because of high accuracy and acceptable precision.

    Full Text Available Background: Social dimensions of health are known to contribute to what is often termed “patient complexity”, which is particularly common among patients with multimorbidity. Health-care professionals require tools to help them identify and manage these aspects of patient needs. Objectives: To examine: (i the Patient Centered Assessment Method (PCAM, a tool for assessing patient complexity in ways that are sensitive to the biopsychosocial dimensions of health, in primary care settings in Scotland; (ii the impact of the PCAM on referral patterns and its perceived value; and (iii the PCAM’s perceived applicability for use in a complex patient population. Design: Two studies are described: (i a mixed-methods prospective cohort study of the implementation of the PCAM in primary care clinics; and (ii a qualitative exploratory study that evaluated the value of the PCAM in a complex patient population. Results: Use of the PCAM did not impact patient satisfaction or perception of practitioners’ empathy, but it did increase both the number of onward referrals per referred patient (9–12% and the proportion of referrals to non-medical services addressing psychological, social, and lifestyle needs. Nurses valued the PCAM, particularly its ability to help them address psychological and social domains of patients’ lives, and found it to be highly relevant for use in populations with known high complexity. Conclusions: The PCAM represents a feasible approach for assessing patient needs with consideration to the social dimensions of health, and allows practitioners to refer patients to a broader range of services to address patient complexity.

    Aline Kirjner Poziomyck

    Full Text Available ABSTRACT Objectives: to determine the nutritional evaluation method that best predicts mortality in 90 days of patients submitted to gastrectomy for gastric cancer. Methods: we conducted a prospective study with 44 patients with gastric cancer, stages II to IIIa, of whom nine were submitted to partial gastrectomy, 34 to total gastrectomy, and one to esophago-gastrectomy. All patients were nutritionally evaluated through the same protocol, up to 72h after hospital admission. The parameters used were Patient-Generated Subjective Global Assessment (PGSGA, classical anthropometry, current weight and height, percentage of weight loss (%WL and body mass index (BMI. We also measured the thickness of the thumb adductor muscle (TAM in both hands, dominant hand (TAMD and non-dominant hand (TAMND, as well as the calculated the prognostic nutritional index (PNI. The laboratory profile included serum levels of albumin, erythrocytes, hemoglobin, hematocrit, leukocytes, and total lymphocytes count (TLC. Results: of the 44 patients studied, 29 (66% were malnourished by the subjective method, 15 being grade A, 18 grade B and 11 grade C. Cases with PGSGA grade B and TAMD 10.2±2.9 mm were significantly associated with higher mortality. The ROC curves (95% confidence interval of both PGSGA and TAMD thickness reliably predicted mortality at 30 and 90 days. No laboratory method allowed predicting mortality at 90 days. Conclusion: PGSGA and the TAMD thickness can be used as preoperative parameters for risk of death in patients undergoing gastrectomy for gastric cancer.

    Full Text Available Background: Blunt abdominal trauma is one of the causes of mortality in emergency department. Free fluid in the abdomen due to intra-abdominal blunt trauma can be determined by the surface probe of ultrasound. Since the importance of this free fluid in hemodynamic stable patients with blunt trauma is associated with the unknown outcome for surgeons, this study was performed to evaluate the role of ultrasound surface probe as a screening method in evaluating the patients with blunt abdominal trauma. Materials and Methods: A descriptive-analytical study was done on 45 patients with blunt abdominal trauma and hemodynamic stability. The patients were evaluated twice during the three-hours, including repeated ultrasound surface probe and clinical examinations. Computerized tomography was also performed. The patients were divided based on the amount of the free fluid in the abdomen during the evaluations into two groups: Fixed or increased, and decreased free fluid. The results of the different evaluated methods were compared using the sensitivity and specificity. Results: From 17 patients with CT abnormalities, free fluid increased in 14 patients (82.4%. Free fluid was decreased in three patients who were discharged well from the surgery service without any complication. Surface probe in prognosis detection had a sensitivity of 82.4% and specificity of 92.9%. The percentage of false positive and negative ultrasound compared with CT scan was 7.1% and 17.6%. Also, positive and negative predictive value of the ultrasound with surface probe was 87.5% and 89.7% respectively. Conclusion: The use of the ultrasound with surface probe in the diagnosis of free fluid in blunt abdominal trauma in hemodynamic stable patients can be considered as a useful screening method.

    Improving technologies for the detection and purification of bone marrow (BM) micrometastatic cells in breast cancer patients should lead to earlier prognosis of the risk of relapse and should make it possible to design more appropriate therapies. The technique used has to overcome the challenges resulting from the small number of target cells (one per million hematopoietic cells) and the heterogeneous expression of micrometastatic cell markers. In the present study, we have assessed the clinical relevance of current methods aimed at detecting rare disseminated carcinoma cells. BM aspirates from 32 carcinoma patients were screened for the presence of micrometastatic cells positive for epithelial cell adhesion molecule and positive for cytokeratins, using optimized immunodetection methods. A comparison with data obtained for 46 control BM aspirates and a correlation with the clinical status of patients were performed. We developed a sensitive and efficient immunomagnetic protocol for the enrichment of BM micrometastases. This method was used to divide 32 breast carcinoma patients into three categories according to their epithelial cell adhesion molecule status. These categories were highly correlated with the recently revised American Joint Committee on Cancer staging system for breast cancer, demonstrating the clinical relevance of this simple and reliable immunomagnetic technique. We also evaluated immunocytochemical detection of cytokeratin-positive cells and cytomorphological parameters. Immunocytochemistry-based methods for the detection of BM micrometastases did not provide any information about the clinical status of patients, but helped to refine the immunomagnetic data by confirming the presence of micrometastases in some cases. We also tested a new density gradient centrifugation system, able to enrich the tumor fraction of BM specimens by twofold to threefold as compared with standard Ficoll methods. These improved methods for the detection of

    The gastric shunting (GSH) method, permitting to control the patients body mass more effectively and promoting complete remission of diabetes mellitus type II, was elaborated. In 2008 - 2009 yrs 29 patients (9 men, 20 women) were operated on for morbid obesity, using shunting interventions. In 21 patients (the first group) a standard GSH was performed, in 8 (second group)--a modified operation. In 18-24 mo the excessive patient's body mass in patients of the first group have reduced by 62.8%, of the second group--by 89.3%. Complete compensation of diabetes mellitus type II with rejection from insulin and other antidiabetic preparations was achieved in 4 patients of the first group and in all--in the second group. Resistence for insulin have had lowered in patients of both groups, including in the first group--in 1,4 times, in the second group--in 3.2 times. Thus, preliminary results accurately demonstrate, that application of a modified GSH method is more effective, concerning the patients body mass reduction and achievement of complete compensation of diabetes mellitus type II.

    A technique for 2D or 3D image/patient registration, PFPM (projection based Fourier phase matching method), is proposed. This technique provides image/patient registration directly from sequential tomographic projection data. The method can also deal with image files by generating 2D Radon transforms slice by slice. The registration in projection space is done by calculating a Fourier invariant (FI) descriptor for each one-dimensional projection datum, and then registering the FI descriptor by the Fourier phase matching (FPM) method. The algorithm has been tested on both synthetic and experimental data. When dealing with translated, rotated and uniformly scaled 2D image registration, the performance of the PFPM method is comparable to that of the IFPM (image based Fourier phase matching) method in robustness, efficiency, insensitivity to the offset between images, and registration time. The advantages of the former are that subpixel resolution is feasible, and it is more insensitive to image noise due to the averaging effect of the projection acquisition. Furthermore, the PFPM method offers the ability to generalize to 3D image/patient registration and to register partial projection data. By applying patient registration directly from tomographic projection data, image reconstruction is not needed in the therapy set-up verification, thus reducing computational time and artefacts. In addition, real time registration is feasible. Registration from partial projection data meets the geometry and dose requirements in many application cases and makes dynamic set-up verification possible in tomotherapy. (author)

    Full Text Available Abstract Background In spite of succesful adoption of electronic patient records (EPR by Norwegian GPs, what constitutes the actual benefits and effects of the use of EPRs in the perspective of the GPs and patients has not been fully characterized. We wanted to study primary care physicians' use of electronic patient record (EPR systems in terms of use of different EPR functions and the time spent on using the records, as well as the potential effects of EPR systems on the clinician-patient relationship. Methods A combined qualitative and quantitative study that uses data collected from focus groups, observations of primary care encounters and a questionnaire survey of a random sample of general practitioners to describe their use of EPR in primary care. Results The overall availability of individual patient records had improved, but the availability of the information within each EPR was not satisfactory. GPs' use of EPRs were efficient and comprehensive, but have resulted in transfer of administrative work from secretaries to physicians. We found no indications of disturbance of the clinician-patient relationship by use of computers in this study. Conclusion Although GPs are generally satisfied with their EPRs systems, there are still unmet needs and functionality to be covered. It is urgent to find methods that can make a better representation of information in large patient records as well as prevent EPRs from contributing to increased administrative workload of physicians.

    To study the changes of visual nystagmography(VNG) in patients with vertebrobasilar transient ischemic vertigo(VBTIV), explore their clinical value in diagnosis of the patients with VBTIV. Thirty-eight patients who complained vertigo and imbalance with VBTIV were selected as experimental group for testing of visual nystagmography (VNG). Twenty normal persons were chosen as control group. The result was analyzed. In the experimental group, there was one case that had spontaneous nystagmus and 29 cases (76.3%) with positional nystagmus. The positional nystagmus intension in those patients was (4.08+/-3.18) degrees/s, which was much higher as compared with the control group( P VNG be used as important diagnostic test for patients with VBTIV and might be helpful for the location diagnosis of VBTIV.

    Auditing of patient safety aims at early detection of risks of adverse events and is intended to encourage the continuous improvement of patient safety. The auditing should be an independent, objective assurance and consulting system. Auditing helps an organisation accomplish its objectives by bringing a systematic, disciplined approach to evaluating and improving the effectiveness of risk management, control, and governance. Audits are broadly conducted in hospitals, but little is known about their effects on the behaviour of healthcare professionals and patient safety outcomes. This study was initiated to evaluate the effects of patient safety auditing in hospital care and to explore the processes and mechanisms underlying these effects. Our study aims to evaluate an audit system to monitor and improve patient safety in a hospital setting. We are using a mixed-method evaluation with a before-and-after study design in eight departments of one university hospital in the period October 2011-July 2014. We measure several outcomes 3 months before the audit and 15 months after the audit. The primary outcomes are adverse events and complications. The secondary outcomes are experiences of patients, the standardised mortality ratio, prolonged hospital stay, patient safety culture, and team climate. We use medical record reviews, questionnaires, hospital administrative data, and observations to assess the outcomes. A process evaluation will be used to find out which components of internal auditing determine the effects. We report a study protocol of an effect and process evaluation to determine whether auditing improves patient safety in hospital care. Because auditing is a complex intervention targeted on several levels, we are using a combination of methods to collect qualitative and quantitative data about patient safety at the patient, professional, and department levels. This study is relevant for hospitals that want to early detect unsafe care and improve patient

    This study presents a method aimed at creating radiotherapy (RT) patient-adjustable whole-body phantoms to permit retrospective and prospective peripheral dose evaluations for enhanced patient radioprotection. Our strategy involves virtual whole-body patient models (WBPM) in different RT treatment positions for both genders and for different age groups. It includes a software tool designed to match the anatomy of the phantoms with the anatomy of the actual patients, based on the quality of patient data available. The procedure for adjusting a WBPM to patient morphology includes typical dimensions available in basic auxological tables for the French population. Adjustment is semi-automatic. Because of the complexity of the human anatomy, skilled personnel are required to validate changes made in the phantom anatomy. This research is part of a global project aimed at proposing appropriate methods and software tools capable of reconstituting the anatomy and dose evaluations in the entire body of RT patients in an adapted treatment planning system (TPS). The graphic user interface is that of a TPS adapted to obtain a comfortable working process. Such WBPM have been used to supplement patient therapy planning images, usually restricted to regions involved in treatment. Here we report, as an example, the case of a patient treated for prostate cancer whose therapy planning images were complemented by an anatomy model. Although present results are preliminary and our research is ongoing, they appear encouraging, since such patient-adjusted phantoms are crucial in the optimization of radiation protection of patients and for follow-up studies.

    Post-traumatic stress disorder has been detected in patients after treatment in intensive care unit. The main goal of this study is to review the psychological aspects and therapeutic interventions on those patients after their treatment on intensive care unit. Thirty eight articles have been included. The prevalence of post-traumatic stress disorder has varied from 17% up to 30% and the incidence from 14% to 24%. The risk factors were: previous anxiety historic, depression or panic, having delusional traumatic memories (derived from psychic formations as dreams and delirium), belief effects, depressive behavior, stressing experiences and mechanical ventilation. High doses of opiates, symptoms caused by sedation or analgesia reduction and the use of lorazepam were related with the increase of delirium and delusional memory. The disorder sintomatology can be reduced with hydrocortisone administration, with daily sedation interruption. No other effectiveness psychological intervention study was found.

    Background: This study investigated patients’ understanding of the role of music in coping and in influencing their well-being. Methods: A qualitative study was conducted based on semi-structured interviews with 17 cancer patients. Participants were chosen from a group of patients who had listened to or played music as a means of coping with their illness. Results: The study shows the importance of considering the roles that different kinds of music play in coping with cancer. The music of nature, healing music, religious music and cheerful music each have different benefits for patients. Conclusions: A patient's situation and his or her individual characteristics determine the types of music that can act as a useful or harmful coping strategy. Therefore, it is essential to investigate the types of individual characteristics that can make listening to different kinds of music a helpful or harmful coping method. PMID:23805166

    OBJECT Radioactive phosphorus-32 (P32) has been used as brachytherapy for craniopharyngiomas with the hope of providing local control of enlarging tumor cysts. Brachytherapy has commonly been used as an adjunct to the standard treatment of surgery and external-beam radiation (EBR). Historically, multimodal treatment, including EBR, has shown tumor control rates as high as 70% at 10 years after treatment. However, EBR is associated with significant long-term risks, including visual deficits, endocrine dysfunction, and cognitive decline. Theoretically, brachytherapy may provide focused local radiation that controls or shrinks a symptomatic cyst without exposing the patient to the risks of EBR. For this study, the authors reviewed their experiences with craniopharyngioma patients treated with P32 brachytherapy as the primary treatment without EBR. The authors reviewed these patients' records to evaluate whether this strategy effectively controls tumor growth, thus avoiding the need for further surgery or EBR. METHODS The authors performed a retrospective review of pediatric patients treated for craniopharyngioma between 1997 and 2004. This was the time period during which the authors' institution had a relatively high use of P32 for treatment of cystic craniopharyngioma. All patients who had surgery and injection of P32 without EBR were identified. The patient records were analyzed for complications, cyst control, need for further surgery, and need for future EBR. RESULTS Thirty-eight patients were treated for craniopharyngioma during the study period. Nine patients (23.7%) were identified who had surgery (resection or biopsy) with P32 brachytherapy but without initial EBR. These 9 patients represented the study group. For 1 patient (11.1%), there was a complication with the brachytherapy procedure. Five patients (55.5%) required subsequent surgery. Seven patients (77.7%) required subsequent EBR for tumor growth. The mean time between the injection of P32 and

    BACKGROUND: Narcolepsy causes abnormalities in the control of wake-sleep, non-rapid-eye-movement (non-REM) sleep and REM sleep, which includes specific eye movements (EMs). In this study, we aim to evaluate EM characteristics in narcolepsy as compared to controls using an automated detector....... RESULTS: NT1 patients had significantly less EMs during wake, N1, and N2 sleep and more EMs during REM sleep compared to clinical controls, and significantly less EMs during wake and N1 sleep compared to NT2 patients. Furthermore, NT1 patients showed less EMs during NREM sleep in the first sleep cycle....... METHODS: We developed a data-driven method to detect EMs during sleep based on two EOG signals recorded as part of a polysomnography (PSG). The method was optimized using the manually scored hypnograms from 36 control subjects. The detector was applied on a clinical sample with subjects suspected...

  17. An evidence-based patient-centered method makes the biopsychosocial model scientific.

    2013-06-01

    To review the scientific status of the biopsychosocial (BPS) model and to propose a way to improve it. Engel's BPS model added patients' psychological and social health concerns to the highly successful biomedical model. He proposed that the BPS model could make medicine more scientific, but its use in education, clinical care, and, especially, research remains minimal. Many aver correctly that the present model cannot be defined in a consistent way for the individual patient, making it untestable and non-scientific. This stems from not obtaining relevant BPS data systematically, where one interviewer obtains the same information another would. Recent research by two of the authors has produced similar patient-centered interviewing methods that are repeatable and elicit just the relevant patient information needed to define the model at each visit. We propose that the field adopt these evidence-based methods as the standard for identifying the BPS model. Identifying a scientific BPS model in each patient with an agreed-upon, evidence-based patient-centered interviewing method can produce a quantum leap ahead in both research and teaching. A scientific BPS model can give us more confidence in being humanistic. In research, we can conduct more rigorous studies to inform better practices. Copyright © 2013 Elsevier Ireland Ltd.

    The application of laser photoacoustic spectroscopy (LPAS) for fast and precise measurements of breath biomarkers has opened up new promises for monitoring and diagnostics in recent years, especially because breath test is a non-invasive method, safe, rapid and acceptable to patients. Our study involved assessment of breath ethylene and breath ammonia levels in patients with renal failure receiving haemodialysis (HD) treatment. Breath samples from healthy subjects and from patients with renal failure were collected using chemically inert aluminized bags and were subsequently analyzed using the LPAS technique. We have found out that the composition of exhaled breath in patients with renal failure contains not only ethylene, but also ammonia and gives valuable information for determining efficacy and endpoint of HD. Analysis of ethylene and ammonia traces from the human breath may provide insight into severity of oxidative stress and metabolic disturbances and may ensure optimal therapy and prevention of pathology at patients on continuous HD.

    There is increasing recognition of the importance of patient preferences and methodologies to measure them. In this article, methods to quantify patient preferences are reviewed, with a focus on discrete choice experiments. In a discrete choice experiment, patients are asked to choose between 2 or more treatments. The results can be used to quantify the relative importance of treatment outcomes and/or other considerations relevant to medical decision making. Conducting and interpreting a discrete choice experiment requires multiple steps and an understanding of the potential biases that can arise, which we review in this article with examples in rheumatic diseases.

    2008-12-01

    Full Text Available Abstract Background Diabetic type 1 patients are often advised to use dose adjustment guidelines to calculate their doses of insulin. Conventional methods of measuring patients' adherence are not applicable to these cases, because insulin doses are not determined in advance. We propose a method and a number of indicators to measure patients' conformance to these insulin dosing guidelines. Methods We used a database of logbooks of type 1 diabetic patients who participated in a summer camp. Patients used a guideline to calculate the doses of insulin lispro and glargine four times a day, and registered their injected doses in the database. We implemented the guideline in a computer system to calculate recommended doses. We then compared injected and recommended doses by using five indicators that we designed for this purpose: absolute agreement (AA: the two doses are the same; relative agreement (RA: there is a slight difference between them; extreme disagreement (ED: the administered and recommended doses are merely opposite; Under-treatment (UT and over-treatment (OT: the injected dose is not enough or too high, respectively. We used weighted linear regression model to study the evolution of these indicators over time. Results We analyzed 1656 insulin doses injected by 28 patients during a three weeks camp. Overall indicator rates were AA = 45%, RA = 30%, ED = 2%, UT = 26% and OT = 30%. The highest rate of absolute agreement is obtained for insulin glargine (AA = 70%. One patient with alarming behavior (AA = 29%, RA = 24% and ED = 8% was detected. The monitoring of these indicators over time revealed a crescendo curve of adherence rate which fitted well in a weighted linear model (slope = 0.85, significance = 0.002. This shows an improvement in the quality of therapeutic decision-making of patients during the camp. Conclusion Our method allowed the measurement of patients' adherence to their insulin adjustment guidelines. The indicators that we

    Full Text Available An abnormally small oral orifice is defined as microstomia. Microstomia may result from epidermolysis bullosa (EB, which consists of a group of disorders characterized by the presence of mechanical fragility of the skin with recurrent development of blisters and vesicles, resulting from minor mechanical friction or trauma. Since such patients have a small oral aperture, it may be impossible to take impression and fabricate dentures using conventional methods. In this article, a simple method for taking preliminary impressions from upper and lower edentulous ridges in one patient with limited mouth opening and then preparing the complete denture with custom denture teeth in a single unit was described.

    Epidural hematoma (EH) is a serious clinical event observed in 2% of head trauma patients. Studies regarding the effects of epidural hematoma volume (EHV) on prognosis are not sufficient. In this study, we applied the volume fraction approach of the stereological method to estimate the hematoma to brain volume fraction (HBVF), and investigated the relation between the HBVF and prognosis. Fifty-nine EH patients (46 male and 13 female subjects, with average age of 21 years) admitted to the emergency clinic were included. The HBVF was estimated on the printed films of cranial computed tomography scans. For this purpose, common point counting grids were superimposed over the scan frames. According to the clinical results, patients were divided into three groups as complete recovery (43), disability (8) and exitus (8). The HBVF was compared with the clinical results. HBVF was determined as 4.6% in the patients with recovery, 8.1% in disability, and 7.6% in exitus patients. The HBVF values were lowest in recovery patients, and the difference between the recovery and the other two groups was statistically significant (p=0.007). However, there was no statistically significant difference in HBVF between disability and exitus patients (p>0.05). In conclusion, the HBVF can be an important tool to determine prognosis, and it can be measured using the volume fraction approach of stereological methods as developed in the present study.

    The flexion relaxation phenomenon (FRP) can be defined as a reduction or silence of myoelectric activity of the lumbar erector spinae muscle during full trunk flexion. It is typically absent in patients with chronic low back pain (LBP). Before any broad clinical utilization of this neuromuscular response can be made, effective, standardized, and accurate methods of identifying FRP limits are needed. However, this phenomenon is clearly more difficult to detect for LBP patients than for healthy patients. The main goal of this study is to develop an automated method based on wavelet transformation that would improve time point limits detection of surface electromyography signals of the FRP in case of LBP patients. Conventional visual identification and proposed automated methods of time point limits detection of relaxation phase were compared on experimental data using criteria of accuracy and repeatability based on physiological properties. The evaluation demonstrates that the use of wavelet transform (WT) yields better results than methods without wavelet decomposition. Furthermore, methods based on wavelet per packet transform are more effective than algorithms employing discrete WT. Compared to visual detection, in addition to demonstrating an obvious saving of time, the use of wavelet per packet transform improves the accuracy and repeatability in the detection of the FRP limits. These results clearly highlight the value of the proposed technique in identifying onset and offset of the flexion relaxation response in LBP subjects.

    Interpretation guidelines are needed for patient-reported outcome (PRO) measures' change scores to evaluate efficacy of an intervention and to communicate PRO results to regulators, patients, physicians, and providers. The 2009 Food and Drug Administration (FDA) Guidance for Industry Patient-Reported Outcomes (PRO) Measures: Use in Medical Product Development to Support Labeling Claims (hereafter referred to as the final FDA PRO Guidance) provides some recommendations for the interpretation of change in PRO scores as evidence of treatment efficacy. This article reviews the evolution of the methods and the terminology used to describe and aid in the communication of meaningful PRO change score thresholds. Anchor- and distribution-based methods have played important roles, and the FDA has recently stressed the importance of cross-sectional patient global assessments of concept as anchor-based methods for estimation of the responder definition, which describes an individual-level treatment benefit. The final FDA PRO Guidance proposes the cumulative distribution function (CDF) of responses as a useful method to depict the effect of treatments across the study population. While CDFs serve an important role, they should not be a replacement for the careful investigation of a PRO's relevant responder definition using anchor-based methods and providing stakeholders with a relevant threshold for the interpretation of change over time.

    1993-06-01

    The classical management of patients on oral anticoagulant therapy included hospitalisation, cessation of the anticoagulant agent, and extraction of teeth when the prothrombine levels rise. This method was substituted in the High Risk Dental Clinic at Barzilai Medical Center in Ashkelon by use of a tissue sealant (Tisseel) which does not need hospitalisation nor cessation of the anticoagulant therapy. In comparing the last 23 sessions employing the former method to the first 23 sessions using the new method there were significant differences in the cost effectiveness for the health system, provider, insurer and patient. Despite the fact that from the health system point of view the new method is much more cost effective, there is no financial incentive for the provider (hospital) nor awareness on the part of the insurer (General Sick Fund) to embrace it and 'market' it.

    Objective: To study the effects of low-flux hemodialysis (LFHD), high-flux hemodialysis (HFHD) and hemodiafiltration (HDF) on the serum inflammatory cytokine in maintenance hemodialysis (MHD) patients. Methods: Sixty MHD patients were randomly divided into LFHD group, HFHD group and HDF group. Results: The levels of serum CRP, IL-6, IL-8 and TNF-α were detected in three groups and control group. The results showed that levels of CRP, IL-6, IL-8 and TNF-α in patients with MHD before treatment were much higher than these in control group (P 0.05). The levels of CRP, IL-6, IL-8 and TNF-α did not significantly decrease in patients with HFHD after the first hemodialysis (P>0.05). The levels of CRP, IL-6, IL-8 and TNF-α decreased markedly in patients with HFHD after 6 months hemodialysis (P<0.05). The levels of CRP, IL-6, IL-8 and TNF-α decreased significantly in patients with HDF after the first hemodialysis and after 6 months (P<0.05). The levels of CRP, IL-6, IL-8 and TNF-α in HDF group were significantly lower than those in HFHD group after 6 months (P<0.05). Conclusion: There was microinflammatory state in MHD patients. The lowering of patients' serum CRP, IL-6, IL-8 and TNF-α levels and thus the recovery from microinflammatory state may be achieved by HDF, HFHD, and HFHD preferably by HDF. (authors)

    Background/Aims The goal of this study was to examine the reliability and validity of the Changsha version of the Montreal Cognitive Assessment (MoCA-CS) in ischemic cerebrovascular disease patients of Hunan Province, China, and to explore the optimal cutoff score for detecting vascular cognitive impairment-no dementia (VCI-ND) and vascular dementia (VD). Methods Three hundred and thirty-eight ischemic cerebrovascular disease patients (131 with normal cognition, 111 with VCI-ND, and 96 with VD) and 132 healthy controls were recruited. All participants accepted examination by the MoCA-CS, Mini-Mental State Examination (MMSE), and other related scales. A detailed neuropsychological battery was used for making a final cognitive diagnosis. SPSS 16.0 statistical software was used for reliability, validity examination, and optimal cutoff score detection. Results Cronbach's α of the MoCA-CS was 0.884, and test-retest and interrater reliability of the MoCA-CS were 0.966 and 0.926, respectively. MoCA-CS scores were highly correlated with MMSE scores (r = 0.867) and simplified intelligence quotients (r = 0.822). The results indicate that 1 point should be added for subjects with less than 6 years of education, and that the optimal cutoff score for detecting VCI-ND is 26/27 (sensitivity 96.1%, specificity 75.6%), whereas the optimal cutoff score for detecting VD is 16/17 (sensitivity 92.7%, specificity 96.3%). Conclusion The MoCA-CS has good reliability and validity, and is a useful cognitive screening instrument for detecting VCI in the Chinese population. PMID:23637698

    Full Text Available Background. There are several diagnostic methods for Helicobacter pylori (H. pylori infection. A cost-effective analysis is needed to decide on the optimal diagnostic method. The aim of this study was to determine a cost-effective diagnostic method in patients with atrophic gastritis (AG. Methods. A decision-analysis model including seven diagnostic methods was constructed for patients with AG diagnosed by esophagogastroduodenoscopy. Expected values of cost and effectiveness were calculated for each test. Results. If the prevalence of H. pylori in the patients with AG is 85% and CAM-resistant H. pylori is 30%, histology, stool H. pylori antigen (SHPAg, bacterial culture (BC, and urine H. pylori antibody (UHPAb were dominated by serum H. pylori IgG antibody (SHPAb, rapid urease test (RUT, and urea breath test (UBT. Among three undominated methods, the incremental cost-effective ratios (ICER of RUT versus SHPAb and UBT versus RUT were $214 and $1914, respectively. If the prevalence of CAM-sensitive H. pylori was less than 55%, BC was not dominated, but its H. pylori eradication success rate was 0.86. Conclusions. RUT was the most cost-effective at the current prevalence of CAM-resistant H. pylori. BC could not be selected due to its poor effectiveness even if CAM-resistant H. pylori was more than 45%.

    Deep brain stimulation (DBS) of the thalamus is a safe and efficient method for treatment of disabling tremor in patient with essential tremor (ET). However, successful tremor suppression after surgery requires careful selection of stimulus parameters. Our aim was to examine the possible use of certain quantitative methods for evaluating the efficacy of thalamic DBS in ET patients in clinical practice, and to compare these methods with traditional clinical tests. We examined 22 patients using the Essential Tremor Rating Scale (ETRS) and quantitative assessment of tremor with the stimulator both activated and deactivated. We used an accelerometer (CATSYS tremor Pen) for quantitative measurement of postural tremor, and a eurythmokinesimeter (EKM) to evaluate kinetic tremor in a rapid pointing task. The efficacy of DBS on tremor suppression was prominent irrespective of the method used. The agreement between clinical rating of postural tremor and tremor intensity as measured by the CATSYS tremor pen was relatively high (rs = 0.74). The agreement between kinetic tremor as assessed by the ETRS and the main outcome variable from the EKM test was low (rs = 0.34). The lack of agreement indicates that the EKM test is not comparable with the clinical test. Quantitative methods, such as the CATSYS tremor pen, could be a useful complement to clinical tremor assessment in evaluating the efficacy of DBS in clinical practice. Future studies should evaluate the precision of these methods and long-term impact on tremor suppression, activities of daily living (ADL) function and quality of life.

    One of the most important issues in morning report sessions is the number of patients. The aim of this study was to investigate and compare the number of cases reported in the morning report sessions in terms of case-based and conventional methods from the perspective of pediatric residents of Mashhad University of Medical Sciences. The present study was conducted on 24 pediatric residents of Mashhad University of Medical Sciences in the academic year 2014-2015. In this survey, the residents replied to a 20-question researcher-made questionnaire that had been designed to measure the views of residents regarding the number of patients in the morning report sessions using case-based and conventional methods. The validity of the questionnaire was confirmed by experts' views and its reliability by calculating Cronbach's alpha coefficients. Data were analyzed by t-test analysis. The mean age of the residents was 30.852 ± 2.506, and 66.6% of them were female. The results showed that there was no significant relationship among the variables of academic year, gender, and residents' perspective to choosing the number of patients in the morning report sessions (P > 0.05). T-test analysis showed a significant relationship among the average scores of residents in the selection of the case-based method in comparison to the conventional method (P case-based morning report was preferred compared to the conventional method. This method makes residents pay more attention to the details of patients' issues and therefore helps them to better plan how to address patient problems and improve their differential diagnosis skills.

Monocular visual performance using full correction was compared with visual performance using spherical equivalent correction. Testing consisted of high- and low-contrast visual acuity, contrast sensitivity, and reading acuity and speed using the Radner Reading Charts.Results: Thirty-eight of 40 subjects completed testing. Visual acuities at three contrast levels (100%, 25%, and 9% were significantly better using full correction than when using spherical equivalent correction (all P < 0.001. For contrast sensitivity testing under photopic, mesopic, and mesopic with glare conditions, only one out of twelve outcomes demonstrated a significant improvement with full correction compared with spherical equivalent correction (at six cycles per degree under mesopic without glare conditions, P = 0.046. Mean reading speed was numerically faster with full correction across all print sizes, reaching statistical significance at logarithm of the reading acuity determination (logRAD 0.2, 0.7, and 1.1 (P , 0.05. Statistically significant differences also favored full correction in logRAD score (P = 0.0376, corrected maximum reading speed (P < 0.001, and logarithm of the minimum angle of resolution/logRAD ratio (P < 0.001.Conclusions: In this study of pseudophakic subjects with low levels of postoperative astigmatism, full correction yielded significantly better reading performance and high- and low-contrast visual acuity than spherical equivalent correction, suggesting that cataractous patients may benefit from surgical

    Extended red blood cell (RBC) antigen matching is recommended to limit alloimmunization in patients with sickle cell disease (SCD). DNA-based testing to predict blood group phenotypes has enhanced availability of antigen-negative donor units and improved typing of transfused patients, but replacement of routine serologic typing for non-ABO antigens with molecular typing for patients has not been reported. This study compared the historical RBC antigen phenotypes obtained by hemagglutination methods with genotype predictions in 494 patients with SCD. For discrepant results, repeat serologic testing was performed and/or investigated by gene sequencing for silent or variant alleles. Seventy-one typing discrepancies were identified among 6360 antigen comparisons (1.1%). New specimens for repeat serologic testing were obtained for 66 discrepancies and retyping agreed with the genotype in 64 cases. One repeat Jk(b-) serologic phenotype, predicted Jk(b+) by genotype, was found by direct sequencing of JK to be a silenced allele, and one N typing discrepancy remains under investigation. Fifteen false-negative serologic results were associated with alleles encoding weak antigens or single-dose Fy(b) expression. DNA-based RBC typing provided improved accuracy and expanded information on RBC antigens compared to hemagglutination methods, leading to its implementation as the primary method for extended RBC typing for patients with SCD at our institution. © 2015 AABB.

    Facial defects are either congenital or caused by trauma or cancer where most of them affect the person appearance. The emotional pressure and low self-esteem are problems commonly related to patient with facial defect. To overcome this problem, silicone prosthesis was designed to cover the defect part. This study describes the techniques in designing and fabrication for facial prosthesis applying computer aided method and manufacturing (CADCAM). The steps of fabricating the facial prosthesis were based on a patient case. The patient was diagnosed for Gorlin Gotz syndrome and came to Hospital Universiti Sains Malaysia (HUSM) for prosthesis. The 3D image of the patient was reconstructed from CT data using MIMICS software. Based on the 3D image, the intercanthal and zygomatic measurements of the patient were compared with available data in the database to find the suitable nose shape. The normal nose shape for the patient was retrieved from the nasal digital library. Mirror imaging technique was used to mirror the facial part. The final design of facial prosthesis including eye, nose and cheek was superimposed to see the result virtually. After the final design was confirmed, the mould design was created. The mould of nasal prosthesis was printed using Objet 3D printer. Silicone casting was done using the 3D print mould. The final prosthesis produced from the computer aided method was acceptable to be used for facial rehabilitation to provide better quality of life.

    Several new and improved modalities, scanners, and protocols, together referred to as image-acquisition methods (IAMs), are being developed to provide reliable quantitative imaging. Objective evaluation of these IAMs on the clinically relevant quantitative tasks is highly desirable. Such evaluation is most reliable and clinically decisive when performed with patient data, but that requires the availability of a gold standard, which is often rare. While no-gold-standard (NGS) techniques have been developed to clinically evaluate quantitative imaging methods, these techniques require that each of the patients be scanned using all the IAMs, which is expensive, time consuming, and could lead to increased radiation dose. A more clinically practical scenario is where different set of patients are scanned using different IAMs. We have developed an NGS technique that uses patient data where different patient sets are imaged using different IAMs to compare the different IAMs. The technique posits a linear relationship, characterized by a slope, bias, and noise standard-deviation term, between the true and measured quantitative values. Under the assumption that the true quantitative values have been sampled from a unimodal distribution, a maximum-likelihood procedure was developed that estimates these linear relationship parameters for the different IAMs. Figures of merit can be estimated using these linear relationship parameters to evaluate the IAMs on the basis of accuracy, precision, and overall reliability. The proposed technique has several potential applications such as in protocol optimization, quantifying difference in system performance, and system harmonization using patient data.

    We describe the concept and method of video elicitation interviews and provide practical guidance for primary care researchers who want to use this qualitative method to investigate physician-patient interactions. During video elicitation interviews, researchers interview patients or physicians about a recent clinical interaction using a video recording of that interaction as an elicitation tool. Video elicitation is useful because it allows researchers to integrate data about the content of physician-patient interactions gained from video recordings with data about participants' associated thoughts, beliefs, and emotions gained from elicitation interviews. This method also facilitates investigation of specific events or moments during interactions. Video elicitation interviews are logistically demanding and time consuming, and they should be reserved for research questions that cannot be fully addressed using either standard interviews or video recordings in isolation. As many components of primary care fall into this category, high-quality video elicitation interviews can be an important method for understanding and improving physician-patient interactions in primary care.

    Although broncho-alveolar lavage (BAL) culture and protected specimen brush (PSB) are regarded as the most effective methods in the diagnosis of VAP, a simple endotracheal aspiration (EA) is frequently performed during routine care, because of its simplicity and low cost. We compared the effectiveness of EA with BAL and PSB in VAP patients. Sixty-one adult VAP patients, ventilated for longer than 48 h, were cultured with all three methods. Positive cultures were obtained from 63.9% of patients, with Acinetobacter baumannii being the most common pathogen. There was a high positive correlation between simple aspirates and BAL (k 0.817, CI 0.664-0.840, p aspirates and PSB (k 0.667, CI 0.483-0.871, p aspirate culturing, compared to BAL and PSB, it can be used successfully in most cases.

    Full Text Available Abstract Background Although many symptoms of Major Depressive Disorder (MDD are assessed through patient-report, there are currently no patient-reported outcome (PRO instruments that incorporate documented evidence of patient input in PRO instrument development. A review of existing PROs used in MDD suggested the need to conduct qualitative research with patients with MDD to better understand their experience of MDD and develop an evaluative instrument with content validity. The aim of this study was to develop a disease-specific questionnaire to assess symptoms important and relevant to adult MDD patients. Methods The questionnaire development involved qualitative interviews for concept elicitation, instrument development, and cognitive interviews to support content validity. For concept elicitation, ten MDD severity-specific focus group interviews with thirty-eight patients having clinician-confirmed diagnoses of MDD were conducted in January 2009. A semi-structured discussion guide was used to elicit patients' spontaneous descriptions of MDD symptoms. Verbatim transcripts of focus groups were coded and analyzed to develop a conceptual framework to describe MDD. A PRO instrument was developed by operationalizing concepts elicited in the conceptual framework. Cognitive interviews were carried out in patients (n = 20 to refine and test the content validity of the instrument in terms of item relevance and comprehension, instructions, recall period, and response categories. Results Concept elicitation focus groups identified thirty-five unique concepts falling into several domains: i emotional, ii cognitive, iii motivation, iv work, v sleep, vi appetite, vii social, viii activities of daily living, ix tired/fatigue, x body pain, and xi suicidality. Concept saturation, the point at which no new relevant information emerges in later interviews, was achieved for each of the concepts. Based on the qualitative findings, the PRO instrument developed

    Full Text Available Objective: To study the influence of general anesthesia, epidural anesthesia and combined spinal and epidural anesthesia method on stress reaction and hemodynamics for elderly orthopedics patients during operations. Methods: A total of 90 cases of elder patients who received orthopedic operations were randomly divided to group A, B and C, with 30 cases per group. Three groups of patients were separately given by general anesthesia, epidural anesthesia and combined spinal and epidural anesthesia for operations; The variations of adrenocorticotrophic hormone (ACTH, Cortisol (Cor, β-endorphin (β-EP, Angiotensin- Ⅱ(Ang-Ⅱ, heart rate (HR and blood pressure (SBP, DBP on patients in three groups before anesthesia (T0, during skin incision (T1, after skin incision (T2 and extubation after operation (T3 were compared and analyzed. Results: During T1, T2, ACTH, Cor, β-EP and Ang-Ⅱlevels in 3 groups of patients were significantly higher than those during T0; SBP and DBP were significantly lower than that during T0; HR during T2 was significantly lower than that during T0; During T3, every index in 3 groups were recovered to levels close to that during T0; During T1, T2, ACTH, Cor, β-EP, Ang-Ⅱ levels in group B and C were significantly lower than that in group A. And levels in C was lower than that in B; SBP and DBP in group B and C were significantly higher than A. No HR statistical significance appeared between each group. Conclusions: During clinical anesthesia, we should choose suitable anesthesia method combined with actual situations of patients. Combined spinal and epidural anesthesia had a slight influence on hemodynamics of elder orthopedics patients during operation, and it could effectively alleviate stress reaction during operation.

    Full Text Available Abstract Background Numerous studies examined factors in promoting a patient preference for active participation in treatment decision making with only modest success. The purpose of this study was to identify types of patients wishing to participate in treatment decisions as well as those wishing to play a completely active or passive role based on a Germany-wide survey of dialysis patients; using a prediction typal analysis method that defines types as configurations of categories belonging to different attributes and takes particularly higher order interactions between variables into account. Methods After randomly splitting the original patient sample into two halves, an exploratory prediction configural frequency analysis (CFA was performed on one-half of the sample (n = 1969 and the identified types were considered as hypotheses for an inferential prediction CFA for the second half (n = 1914. 144 possible prediction types were tested by using five predictor variables and control preferences as criterion. An α-adjustment (0.05 for multiple testing was performed by the Holm procedure. Results 21 possible prediction types were identified as hypotheses in the exploratory prediction CFA; four patient types were confirmed in the confirmatory prediction CFA: patients preferring a passive role show low information seeking preference, above average trust in their physician, perceive their physician's participatory decision-making (PDM-style positive, have a lower educational level, and are 56-75 years old (Type 1; p 76 years old (Type 2; p p p Conclusions The method prediction configural frequency analysis was newly introduced to the research field of patient participation and could demonstrate how a particular control preference role is determined by an association of five variables.

    Hyperphosphatemia is an independent predictor for cardiovascular and all-cause mortality in patients undergoing peritoneal dialysis (PD). The study aimed to investigate the effect of dietary intervention on reducing serum phosphate concentration in hyperphosphatemic PD patients. In this single-center clinical trial, 97 prevalent PD patients with serum phosphate concentration ≥ 1.6 mmol/l were allocated to the intervention (n = 48) or control (n = 49) group and followed up for 1 year. In addition to phosphate binder (calcium carbonate) therapy, patients in the intervention group were intensively educated to reduce phosphate-rich food intake and improve cooking methods. While stable in the control group (1.97 ± 0.20 to 1.94 ± 0.35 mmol/l, p > 0.05), the serum phosphate concentration decreased significantly in the intervention group (1.98 ± 0.28 to 1.65 ± 0.33 mmol/l, p = 0.015) concurrently with the drop in dietary phosphate intake (13.03 ± 3.39 to 10.82 ± 3.00 mg/kg ideal body weight/day, p = 0.001). Moreover, after 6 months of intervention, fewer patients needed to use calcium carbonate (from 64.6% to 41.5%, p = 0.029) and the medicine dose reduced significantly (from 2.25 (0, 3.94) to 0 (0, 1.50) g/day, p cooking methods attenuated hyperphosphatemia in PD patients. It suggests that regular assessment of dietary phosphate intake and modification of diet recipe and cooking methods are essential for hyperphosphatemia treatment in PD patients in addition to phosphate binder therapy.

    Full Text Available We describe how scale space methods can be used for quantitative analysis of blood glucose concentrations from type 2 diabetes patients. Blood glucose values were recorded voluntarily by the patients over one full year as part of a self-management process, where the time and frequency of the recordings are decided by the patients. This makes a unique dataset in its extent, though with a large variation in reliability of the recordings. Scale space and frequency space techniques are suited to reveal important features of unevenly sampled data, and useful for identifying medically relevant features for use both by patients as part of their self-management process, and provide useful information for physicians.

    Seizure threshold (ST) in electroconvulsive therapy (ECT) has not been reported previously in Japanese patients. We investigated ST in bilateral ECT in Japanese patients using the dose-titration method. The associations between demographic and clinical characteristics and ST were analyzed to identify the predictors of ST. Finally, the validity of the half-age method for the stimulus dose was evaluated. Fifty-four Japanese patients with mood disorder, schizophrenia, and other psychotic disorders received an acute course of bilateral ECT using a brief-pulse device. ST was determined at the first session using a fixed titration schedule. ST was correlated with age, sex, body mass index, history of previous ECT, and psychotropic drugs on multiple regression analysis. Furthermore, the rate of accomplished seizures was calculated using the half-age method. Mean ST was 136 mC. ST was influenced by age, sex, history of previous ECT, and medication with benzodiazepines. The accomplished seizure rate using the half-age method was 72%, which was significantly lower in men and subjects on benzodiazepines. ST in Japanese patients was equal to or slightly higher than that previously reported in other ethnic groups, which might be attributable, at least in part, to high prevalence of and large-dose benzodiazepine prescription. Higher age, male gender, no history of ECT, and benzodiazepines were related to higher ST. The half-age method was especially useful in female patients and subjects without benzodiazepine medication. © 2014 The Authors.

    A previously proposed x-ray scatter correction method for dedicated breast computed tomography was further developed and implemented so as to allow for initial patient testing. The method involves the acquisition of a complete second set of breast CT projections covering 360° with a perforated tungsten plate in the path of the x-ray beam. To make patient testing feasible, a wirelessly controlled electronic positioner for the tungsten plate was designed and added to a breast CT system. Other improvements to the algorithm were implemented, including automated exclusion of non-valid primary estimate points and the use of a different approximation method to estimate the full scatter signal. To evaluate the effectiveness of the algorithm, evaluation of the resulting image quality was performed with a breast phantom and with nine patient images. The improvements in the algorithm resulted in the avoidance of introduction of artifacts, especially at the object borders, which was an issue in the previous implementation in some cases. Both contrast, in terms of signal difference and signal difference-to-noise ratio were improved with the proposed method, as opposed to with the correction algorithm incorporated in the system, which does not recover contrast. Patient image evaluation also showed enhanced contrast, better cupping correction, and more consistent voxel values for the different tissues. The algorithm also reduces artifacts present in reconstructions of non-regularly shaped breasts. With the implemented hardware and software improvements, the proposed method can be reliably used during patient breast CT imaging, resulting in improvement of image quality, no introduction of artifacts, and in some cases reduction of artifacts already present. The impact of the algorithm on actual clinical performance for detection, diagnosis and other clinical tasks in breast imaging remains to be evaluated. (paper)

  19. A NEW METHOD FOR PREDICTING SURVIVAL AND ESTIMATING UNCERTAINTY IN TRAUMA PATIENTS

    Directory of Open Access Journals (Sweden)

    V. G. Schetinin

    2017-01-01

    Full Text Available The Trauma and Injury Severity Score (TRISS is the current “gold” standard of screening patient’s condition for purposes of predicting survival probability. More than 40 years of TRISS practice revealed a number of problems, particularly, 1 unexplained fluctuation of predicted values caused by aggregation of screening tests, and 2 low accuracy of uncertainty intervals estimations. We developed a new method made it available for practitioners as a web calculator to reduce negative effect of factors given above. The method involves Bayesian methodology of statistical inference which, being computationally expensive, in theory provides most accurate predictions. We implemented and tested this approach on a data set including 571,148 patients registered in the US National Trauma Data Bank (NTDB with 1–20 injuries. These patients were distributed over the following categories: (1 174,647 with 1 injury, (2 381,137 with 2–10 injuries, and (3 15,364 with 11–20 injuries. Survival rates in each category were 0.977, 0.953, and 0.831, respectively. The proposed method has improved prediction accuracy by 0.04%, 0.36%, and 3.64% (p-value <0.05 in the categories 1, 2, and 3, respectively. Hosmer-Lemeshow statistics showed a significant improvement of the new model calibration. The uncertainty 2σ intervals were reduced from 0.628 to 0.569 for patients of the second category and from 1.227 to 0.930 for patients of the third category, both with p-value <0.005. The new method shows the statistically significant improvement (p-value <0.05 in accuracy of predicting survival and estimating the uncertainty intervals. The largest improvement has been achieved for patients with 11–20 injuries. The method is available for practitioners as a web calculator http://www.traumacalc.org.

    Full Text Available Objectives: Obtaining accurate platelet counts in microcytic blood samples is challenging, even with the most reliable automated haematology analysers. The CELL-DYN™ Sapphire (Abbott Laboratories, Chicago, Illinois, USA analyser uses both optical density and electronic impedance methods for platelet counting. This study aimed to evaluate the accuracy of optical density and electrical impedance methods in determining true platelet counts in thrombocytopaenic samples with microcytosis as defined by low mean corpuscular volume (MCV of red blood cells. Additionally, the impact of microcytosis on platelet count accuracy was evaluated. Methods: This study was carried out between February and December 2014 at the Haematology Laboratory of the Sultan Qaboos University Hospital in Muscat, Oman. Blood samples were collected and analysed from 189 patients with thrombocytopaenia and MCV values of <76 femtolitres. Platelet counts were tested using both optical and impedance methods. Stained peripheral blood films for each sample were then reviewed as a reference method to confirm platelet counts. Results: The platelet counts estimated by the impedance method were on average 30% higher than those estimated by the optical method (P <0.001. The estimated intraclass correlation coefficient was 0.52 (95% confidence interval: 0.41–0.62, indicating moderate reliability between the methods. The degree of agreement between methods ranged from -85.5 to 24.3 with an estimated bias of -30, suggesting that these methods generate different platelet results. Conclusion: The impedance method significantly overestimated platelet counts in microcytic and thrombocytopaenic blood samples. Further attention is therefore needed to improve the accuracy of platelet counts, particularly for patients with conditions associated with microcytosis.

    2011-06-01

    Full Text Available Abstract Background Phenylketonuria (PKU is an autosomal recessive disorder of phenylalanine metabolism. The inability to convert phenylalanine (Phe into tyrosine causes Phe to accumulate in the body. Adherence to a protein restricted diet, resulting in reduced Phe levels, is essential to prevent cognitive decline. Frequent evaluation of plasma Phe levels and, if necessary, adjustment of the diet are the mainstay of treatment. We aimed to assess whether increased self-management of PKU patients and/or their parents is feasible and safe, by providing direct online access to blood Phe values without immediate professional guidance. Methods Thirty-eight patients aged ≥ 1 year participated in a 10 month randomized controlled trial. Patients were randomized into a study group (1 or a control group (2. Group 2 continued the usual procedure: a phone call or e-mail by a dietician in case of a deviant Phe value. Group 1 was given a personal "My PKU" web page with a graph of their recent and previous Phe values, online general information about the dietary treatment and the Dutch PKU follow-up guidelines, and a message-box to contact their dietician if necessary. Phe values were provided on "My PKU" without advice. Outcome measures were: differences in mean Phe value, percentage of values above the recommended range and Phe sample frequency, between a 10-month pre-study period and the study period in each group, and between the groups in both periods. Furthermore we assessed satisfaction of patients and/or parents with the 'My PKU' procedure of online availability. Results There were no significant differences in mean Phe value, percentage of values above recommended range or in frequency of blood spot sampling for Phe determination between the pre-study period and the study period in each group, nor between the 2 groups during the periods. All patients and/or parents expressed a high level of satisfaction with the new way of disease management

    Monitoring patient adherence to HIV antiretroviral therapy (ART) by patient survey is inherently error prone, justifying a need for objective, biological measures affordable in low-resource settings where HIV/AIDS epidemic is highest. In preliminary studies conducted in Ethiopia and South Africa, we observed loss of cysteine cathepsin activity in peripheral blood mononuclear cells of HIV-positive patients on ART. We optimized a rapid protocol for multiplex cathepsin zymography to quantify cysteine cathepsins, and prospectively enrolled 350 HIV-positive, ART-naïve adults attending the Themba Lethu Clinic, Johannesburg, South Africa, to test if suppressed cathepsin activity could be a biomarker of ART adherence (103 patients were included in final analysis). Poor adherence was defined as detectable viral load (>400 copies/ml) or simplified medication adherence questionnaire, 4-6 months after ART initiation. 86 % of patients with undetectable viral loads after 6 months were cathepsin negative, and cathepsin-positive patients were twice as likely to have detectable viral loads (RR 2.32 95 % CI 1.26-4.29). Together, this demonstrates proof of concept that multiplex cathepsin zymography may be an inexpensive, objective method to monitor patient adherence to ART. Low cost of this electrophoresis-based assay makes it a prime candidate for implementation in resource-limited settings.

In preliminary studies conducted in Ethiopia and South Africa, we observed loss of cysteine cathepsin activity in peripheral blood mononuclear cells (PBMCs) of HIV-positive patients on ART.

    Osteogenesis imperfecta (OI) is a hereditary bone fragility disorder that in most patients is caused by mutations affecting collagen type I. Their typical oral and craneofacial characteristics (Dentinogenesis imperfecta type I and class III malocclusion), involve the dentist in the multidisciplinary team that treat these patients. It is usual to perform lateral skull radiographs for the orthodontic diagnosis. In addition, this radiograph is useful to analyse the junctional area between skull base and spine, that could be damaged in OI. Pathology in the craneovertebral junction (CVJ) is a serious complication of OI with a prevalence ranging from rare to 37%. To diagnosis early skull base anomalies in these patients, previously the neurological symptoms have been appear, we make a simple cephalometric analysis of the CVJ. This method has four measurements and one angle. Once we calculate the values of the OI patient, we compare the result with the mean and the standard deviations of an age-appropriate average in healthy controls. If the patient has a result more than 2,5 SDs above the age-appropriate average in healthy controls, we should to refer the patient to his/her pediatrician or neurologist. These doctors have to consider acquiring another diagnostic images to be used to determine cranial base measurements with more reliability. Thereby, dentists who treat these patients, must be aware of the normal radiological anatomy of the cervical spine on the lateral cephalogram.

    The radiation dose for patients can be reduced with many methods and one way is to use abdominal compression. In this study, the radiation dose and image quality for a new patient-controlled compression device were compared with conventional compression and compression in the prone position . To compare radiation dose and image quality of patient-controlled compression compared with conventional and prone compression in general radiography. An experimental design with quantitative approach. After obtaining the approval of the ethics committee, a consecutive sample of 48 patients was examined with the standard clinical urography protocol. The radiation doses were measured as dose-area product and analyzed with a paired t-test. The image quality was evaluated by visual grading analysis. Four radiologists evaluated each image individually by scoring nine criteria modified from the European quality criteria for diagnostic radiographic images. There was no significant difference in radiation dose or image quality between conventional and patient-controlled compression. Prone position resulted in both higher dose and inferior image quality. Patient-controlled compression gave similar dose levels as conventional compression and lower than prone compression. Image quality was similar with both patient-controlled and conventional compression and was judged to be better than in the prone position.

    The increasing prevalence of treated end-stage renal disease and low transplant rates in Africa leads to longer durations on dialysis. Dialysis should not only be aimed at prolonging lives but also improve quality of life (QOL). Using mixed methods, we investigated the QOL of patients on chronic haemodialysis (HD) and peritoneal dialysis (PD). We conducted a cross-sectional study at Tygerberg Hospital in Cape Town, South Africa. All the PD patients were being treated with continuous ambulatory peritoneal dialysis. The KDQOL-SF 1.3 questionnaire was used for the quantitative phase of the study. Thereafter, focus-group interviews were conducted by an experienced facilitator in groups of HD and PD patients. Electronic recordings were transcribed verbatim and analysed manually to identify emerging themes. A total of 106 patients completed questionnaires and 36 of them participated in the focus group interviews. There was no difference between PD and HD patients in the overall KDQOL-SF scores. PD patients scored lower with regard to symptoms (P = 0.005), energy/fatigue (P = 0.025) and sleep (P = 0.023) but scored higher for work status (P = 0.005) and dialysis staff encouragement (P = 0.019) than those on HD. Symptoms and complications were verbalised more in the PD patients, with fear of peritonitis keeping some housebound. PD patients were more limited by their treatment modality which impacted on body image, sexual function and social interaction but there were less dietary and occupational limitations. Patients on each modality acknowledged the support received from family and dialysis staff but highlighted the lack of support from government. PD patients had little opportunity for interaction with one another and therefore enjoyed less support from fellow patients. PD patients experienced a heavier symptom burden and greater limitations related to their dialysis modality, especially with regards to social functioning. The mixed-methods approach

    A language barrier has been shown to be a threat for quality of hospital care. International studies highlighted a lack of adequate noticing, reporting, and bridging of a language barrier. However, studies on the link between language proficiency and patient safety are scarce, especially in Europe. The present study investigates patient safety risks due to language barriers during hospitalization, and the way language barriers are detected, reported, and bridged in Dutch hospital care. We combined quantitative and qualitative methods in a sample of 576 ethnic minority patients who were hospitalized on 30 wards within four urban hospitals. The nursing and medical records of 17 hospital admissions of patients with language barriers were qualitatively analyzed, and complemented by 12 in-depth interviews with care providers and patients and/or their relatives to identify patient safety risks during hospitalization. The medical records of all 576 patients were screened for language barrier reports. The results were compared to patients' self-reported Dutch language proficiency. The policies of wards regarding bridging language barriers were compared with the reported use of interpreters in the medical records. Situations in hospital care where a language barrier threatened patient safety included daily nursing tasks (i.e. medication administration, pain management, fluid balance management) and patient-physician interaction concerning diagnosis, risk communication and acute situations. In 30% of the patients that reported a low Dutch proficiency, no language barrier was documented in the patient record. Relatives of patients often functioned as interpreter for them and professional interpreters were hardly used. The present study showed a wide variety of risky situations in hospital care for patients with language barriers. These risks can be reduced by adequately bridging the language barrier, which, in the first place, demands adequate detecting and reporting of a

    Full Text Available In clinical setting, the symptoms of the impaired motor behavior in patients with different neurological diseases are identified by classical tests incorporated in clinical neurological examination. New computerized methods for objective motor assessment have been recently suggested in the literature. We developed computerized method for assessment and evaluation of arm movement in patients with Parkinson's disease (PD in early phase and in patients with cerebellar syndrome. Method is based on automatic acquisition of hand coordinates during drawing of line and circle, and offline analysis of kinematic parameters (time duration, path length, mean and maximal velocity, velocity profile, and precision. Clinical application is in recognition and follow-up of the impaired kinematic parameters, specific for these two groups of patients. AIM We propose computerized method that consists of two motor tasks: Task 1- drawing a line defined with end points; and Task 2 - drawing a circle defined by referential model. The first task was rather simple with defined direction, and the second included continuous change of the direction that required permanent adjustment. The aim was to detect which kinematic parameters were particularly different in PD and in patients with cerebellar syndrome in relation to healthy controls, and then to apply this method as an additional instrument in clinical evaluation. METHODS Hand trajectories were assessed during simple self-paced 1 point-to-point movement-Task 1; and 2 circle-Task 2, by cordless magnetic mouse in a hand on digitizing board (Drawing board III, 305x457 mm, GTCO Cal Comp Inc. The subjects were seated in a relaxed manner on the chair adjusted to the table height, and instructed not to correct drawn line during performance of a task. The first session was for practicing the tests only, and in the next session, the subjects repeated 5 times each task. All sessions were videotaped with CCD camera. Testing

    During the past decade, major progress has been made in the evolution of technology directed toward the accurate measurement of regional myocardial perfusion in patients. The deficiencies of some of the older methods (thermodilution and gas clearance) are better appreciated and improved approaches (Doppler catheters, positron-emission tomography, and digital subtraction angiography) have been developed. The new approaches should play a major role in research and for most applications the older methods will gradually be replaced. Efforts to bring these new methods to community hospitals and practicing cardiologists should be stimulated. Doppler catheters, positron-emission tomography, and digital-subtraction angiography are commercially available and Doppler catheters and digital-subtraction angiography could be easily incorporated into routine cardiac catheterization procedures. The Doppler catheter is the most inexpensive and probably the simplest to apply. In our opinion, routine measurements of coronary flow reserve will significantly improve the care of patients with coronary obstructive disease and other diseases that impair myocardial perfusion. If coronary reserve measurements are used frequently, patient selection for coronary angioplasty and bypass surgery will no longer depend entirely on visual assessment of percent diameter stenosis, a very poor criterion in many situations. Also, patients with chest pain syndromes, normal coronary vessels, and impaired coronary reserve will be identified and perhaps some effective treatment for this condition will be devised. 77 references

    We evaluated the application of the method of carbohydrate counting performed by 21 patients with type 2 diabetes, 1 year later attending a guidance course. Participants answered a questionnaire to assess patients' adhesion to carbohydrate counting as well as to identify habit changes and the method's applicability, and values of glycated hemoglobin were also analyzed. Most participants (76%) were females, and 25% of them had obesity degree III. There was a statistically significant decrease in glycated hemoglobin from 8.42±0.02% to 7.66±0.01% comparing values before and after counseling. We observed that although patients stated that the method was difficult they understood that carbohydrate counting could allow them make choices and have more freedom in their meals; we also verified if they understood accurately how to replace some foods used regularly in their diets and most patients correctly chose replacements for the groups of bread (76%), beans (67%) and noodles (67%). We concluded that participation in the course led to improved blood glucose control with a significant reduction of glycated hemoglobin, better understanding of food groups and the adoption of healthier eating habits.

    Helicobacter pylori is a principal cause of chronic gastritis (CG), gastric and duodenal ulcers and a major risk factor for gastric cancer in humans. The objective of this study was to determine and compare the prevalence of H. pylori by different detection methods in symptomatic patients of Karachi. A total of 227 biopsy samples were collected from patients having complaints of peptic ulcer disease (PUD), chronic gastritis and/or abdominal discomfort (AD) from three different health providing institutions of Karachi during 2004- 2006 and analyzed for the presence of H. pylori. Comparative evaluation of three different conventional diagnostic techniques with that of a highly specific PCR amplification of ureC gene were carried out and found H. pylori in 62.5%, 64.7%. 68.7% and 59% by PCR, histology, rapid urease test and culture respectively. Out of 227 biopsy samples collected, 120 (52.8%) were H. pylori positive by all methods comprising 62 male patients and 58 female patients. A significant association between H. pylori infection and gastro duodenal diseases was observed. Among 120 H. pylori infected patients 56 were comprised of PUD, 37 with CG, 19 with AD and 8 with Gastric cancer (GCa). The epidemiology of H. p)1/ori infection is also discussed. (author)

  13. Method of Detection of Well-Differentiated Thyroid Cancers in Obese and Non-Obese Patients.

    Full Text Available The incidence of well-differentiated thyroid cancer (WDTC is increasing rapidly. Many authors feel that this increase is due to over-diagnosis and that one of the contributing factors is the increasing use of various imaging studies. The rate of obesity has also been increasing in the United States. It has been suggested that patients with an increased body mass index (BMI kg/m2 have a higher incidence of WDTC than patients with normal BMI. One might hypothesize that thyroid nodules are more difficult to palpate in obese patients and that as more cancers are detected by imaging the apparent rate of increase in WDTC in obese patients would appear to be greater than in non-obese patients. This study was undertaken to evaluate this hypothesis by determining if there is any difference in the way thyroid cancers are initially detected in obese and non-obese patients.The medical records of all 519 patients with a postoperative diagnosis of WDTC who underwent thyroidectomy at NYU Langone Medical Center from January 1, 2007 through August 31, 2010 by the three members of NYU Endocrine Surgery Associates were reviewed. Patients were divided into Non-obese (BMI<30 kg/m2 and Obese (BMI≥30 kg/m2 groups. Patients were also divided by the initial method of detection of their tumor into Palpation, Imaging, and Incidental groups.The final study group contained 270 patients, 181(67% of whom were in the Non-obese Group and 89(33% were in the Obese Group. In the Non-obese group, 81(45% of tumors were found by palpation, 72(40% were found by imaging, and 28(16% were found incidentally. In the Obese group, 40(45% were found by palpation, 38(43% were found by imaging, and 11(12% were found incidentally. These differences were not statistically significant (p-value 0.769.We show that BMI does not play a role in the method of initial detection in patients with WDTC. This suggests that the prevalence of WDTC detected by imaging is not an artifact caused by an

In response, we performed an appraisal of our services, which resulted in the development of a strategy to reduce waiting time and improve quality of service. Infrastructural changes to our clinic’s waiting room, consultation rooms, and back offices were performed, and schedules were redesigned to reduce wait time to 10 minutes and increase consultation time to 20 minutes. Our objective was to identify if this would improve 1 accessibility to caregivers and 2 quality of service and available amenities. Design: We conducted a multi-method survey using 1 a patient flow analysis to analyze the flow of service and understand the impact of our interventions on patient flow and 2 specially designed questionnaires to investigate patients’ perceptions of our wait time and how to improve our services. Results: The results showed that 79% of our respondents were called in to see a doctor within 20 minutes upon arrival. More patients (55% felt that 10–20 minutes was an acceptable wait time. We also observed a perceived increase in satisfaction with wait time (94%. Finally, a large number of patients (97% were satisfied with the quality of service and with the accessibility to caregivers (94%. Conclusion: The majority of our patients were satisfied with the accessibility to our ambulatory clinics and with the quality of services provided. The appraisal of our operational processes using a patient flow analysis also demonstrated how this strategy could effectively be applied to investigate and improve quality of

    Celiac disease is one of the most common diseases in the world. Capsule endoscopy is an alternative way to visualize the entire small intestine without invasiveness to the patient. It is useful to characterize celiac disease, but hours are need to manually analyze the retrospective data of a single patient. Computer-aided quantitative analysis by a deep learning method helps in alleviating the workload during analysis of the retrospective videos. Capsule endoscopy clips from 6 celiac disease patients and 5 controls were preprocessed for training. The frames with a large field of opaque extraluminal fluid or air bubbles were removed automatically by using a pre-selection algorithm. Then the frames were cropped and the intensity was corrected prior to frame rotation in the proposed new method. The GoogLeNet is trained with these frames. Then, the clips of capsule endoscopy from 5 additional celiac disease patients and 5 additional control patients are used for testing. The trained GoogLeNet was able to distinguish the frames from capsule endoscopy clips of celiac disease patients vs controls. Quantitative measurement with evaluation of the confidence was developed to assess the severity level of pathology in the subjects. Relying on the evaluation confidence, the GoogLeNet achieved 100% sensitivity and specificity for the testing set. The t-test confirmed the evaluation confidence is significant to distinguish celiac disease patients from controls. Furthermore, it is found that the evaluation confidence may also relate to the severity level of small bowel mucosal lesions. A deep convolutional neural network was established for quantitative measurement of the existence and degree of pathology throughout the small intestine, which may improve computer-aided clinical techniques to assess mucosal atrophy and other etiologies in real-time with videocapsule endoscopy.

    This paper presents a novel data assimilation method for patient-specific blood flow analysis based on feedback control theory called the physically consistent feedback control-based data assimilation (PFC-DA) method. In the PFC-DA method, the signal, which is the residual error term of the velocity when comparing the numerical and reference measurement data, is cast as a source term in a Poisson equation for the scalar potential field that induces flow in a closed system. The pressure values at the inlet and outlet boundaries are recursively calculated by this scalar potential field. Hence, the flow field is physically consistent because it is driven by the calculated inlet and outlet pressures, without any artificial body forces. As compared with existing variational approaches, although this PFC-DA method does not guarantee the optimal solution, only one additional Poisson equation for the scalar potential field is required, providing a remarkable improvement for such a small additional computational cost at every iteration. Through numerical examples for 2D and 3D exact flow fields, with both noise-free and noisy reference data as well as a blood flow analysis on a cerebral aneurysm using actual patient data, the robustness and accuracy of this approach is shown. Moreover, the feasibility of a patient-specific practical blood flow analysis is demonstrated. Copyright © 2017 John Wiley & Sons, Ltd.

    Scores to predict treatment outcomes have earned a well-deserved place in healthcare practice. However, when used to help achieve excellence in the care of a given disease, scores should also take into account organizational and social aspects. This article aims to create scores to obtain key variables and its application in the management of care of a given disease. We present a method called Epidemiological Planning for Patient Care Trajectory (PELC) and its application in a research of HIV pediatric patients. This case study is presented by means of two studies. The first study deals with the development of the method PELC. The second is HIV Pediatric case-control study based on PELC method. HIV pediatric research - the first practical PELC application - found these four key variables to the individual quality level care trajectories: adherence to ART, attending at least one appointment with the otolaryngologist, attending at least one appointment with social services, and having missed one or more routine appointments. We believe PELC method can be used in researches about any kind of care trajectories, contributing to quality level advancements in health services, with emphasis on patient safety and equity in healthcare.

    To estimate the incidence of disc displacement, disc deformity, and bone changes of the temporomandibular joint in elderly patients with temporomandibular disorders, 55 elderly patients (110 joints) were examined by magnetic resonance imaging. The ages of the patients ranged from 65 to 89 years (average, 70 years). They consisted of 13 men and 42 women. Normal disc position was found in 40 joints (36.4%), anterior disc displacement with reduction in 17 joints (15.5%), and anterior disc displacement without reduction in 53 joints (48.2%) on magnetic resonance imaging. Thirty-eight (71.6%) of the 53 joints with anterior disc displacement without reduction had disc deformity and 33 (62.3%) had bone changes. The frequency of bone changes in the elderly group was higher than that in the younger group. Women had a higher incidence of bone changes than men. (author)

    2017-05-01

    Full Text Available Background: Patient experience is increasingly recognised as an important feature of healthcare quality improvement. However, many of the methods implemented for its collection have significant limitations and reliability issues. This article describes how a UK healthcare organisation worked with medical student volunteers to build capacity for the collection of patient feedback in evidence-informed ways, and summarises student reflections on this process. Aims: To improve the quantity and quality of inpatient feedback, and in doing so provide new learning opportunities for medical students. Conclusions: Patient feedback gathered by volunteers is beneficial to the service and to medical student volunteers. As the feedback gathered is ward-specific, opportunities are created for practice improvements to be identified and acted on. It is feasible for medical students to be trained effectively as volunteers in gathering patient care experiences with adequate support mechanisms in place. Implications for practice: •\tHealthcare services should consider the use of personnel independent of the care team for the collection of patient feedback •\tPatient feedback needs to be shared with practitioners in a timely manner •\tMedical schools should consider this type of volunteering as a unique opportunity for medical students to improve understanding of patients’ experiences of healthcare, and of how care can be person-centred

    Ischaemic stroke is responsible for 80-85% of strokes. There is great interest in finding effective methods of rehabilitation for post-stroke patients. The aim of this study was to assess the results of rehabilitation carried out in the normalization of upper limb muscle tonus in patients, estimated on the Ashworth Scale for Grading Spasticity. The examined group consisted of 60 patients after ischaemic stroke. 10 sessions of NDT-Bobath therapy were provided within 2 weeks (ten days of therapy). Patient examinations using the Ashworth Scale for Grading Spasticity were done twice: the first time on admission and the second after the last session of the therapy to assess rehabilitation effects. Among the patients involved in the study, the results measured on the Ashworth Scale (where possible) were as follows: recovery in 16 cases (26.67%), relapse in 1 case (1.67%), no measurable changes (or change within the same grade of the scale) in 8 cases (13.33%). Statistically significant changes were observed in the health status of the patients. These changes, in the area of muscle tone, were favorable and reflected in the outcomes of the assessment using the Ashworth Scale for Grading Spasticity.

    An intracapsular femoral neck fracture in a young patient is a rare and difficult injury to manage. The occurrence of complications following fixation is multifactorial. Initial displacement and timing and accuracy of reduction are the key factors affecting outcome. The severities of the trauma to the hip and the impact of the intracapsular hematoma also play a role, the importance of which remains poorly understood. The purpose of this study was to evaluate the high incidence of femoral neck fractures treated in our institution over a 7-month period, to record the long-term outcome of these patients, all of whom were treated with contemporary methods of internal fixation, and to highlight the reasons for this injury being termed an "orthopedic emergency" and its differences from the same injury in the elderly population. We performed a retrospective analysis of 12 cases of intracapsular femur neck fracture in patients younger than 50 years treated over 7 months in a regional trauma center. All patients underwent satisfactory reduction and fixation. Nine of the 12 patients had a good outcome at a mean follow-up of 29 months. One patient developed a nonunion of the femoral head requiring total hip arthroplasty, one developed avascular necrosis of the femoral head, and one developed partial avascular necrosis. This compares favorably with other studies.

    Full Text Available The incidence of tuberculosis (TB is high in patients undergoing chronic dialysis than it is in the general population. The diagnosis of TB is often difficult and extrapulmonary involvement is predominant. This study investigates the spectrum of clinical presentations and outcome in dialysis patients during a nine-year period. TB was diagnosed in 41 patients. Anti-TB drugs, adverse effects of therapy, and outcome were noted. Thirty-eight patients (92.6% were on hemodialysis and three were on peritoneal dialysis (7.3%. The mean age at diagnosis was 50.8 years and the male/female ratio was 1.16. Four patients had a history of pulmonary TB. Extrapulmonary involvement was observed in 32 (78 % patients. The bacteriological confirmation was made in 41.46% and histological confirmation was made in 26.83%, and in the rest, the diagnosis was retained on the criterion presumption. Nineteen patients (46.34% developed adverse effects of antitubercular drugs. Eight patients (19.51% died during the study from TB or adverse effects of treatment. Low urea reduction ratio and female sex were associated with poor prognosis in our study. The clinical manifestations of TB in patients on dialysis are quite nonspecific, making timely diagnosis difficult, and delaying the initiation of curative treatment, which is a major determinant of the outcome.

    Urinary albumin excretion is a useful marker in the prognosis of diabetic nephropathy and microvascular diseases. Methods such as enzyme linked immunosorbent assay (ELISA), radio immunoassay(RIA), radial immunodiffusion, albu screen, micro bumin and micral test are usually used for detection and screening of microalbuminuria in these patients. With consideration to the cost of an assay, methods such as ELISA and RIA are not suitable methods for screening purpose. Therefore, the aim of this work is to set a dot immunoblotting method for the measurement and screening of microalbumin in urine samples. The study was conducted during the period August 2001 to June 2003 at the National Research Center for Genetic Engineering and Biotechnology (NRCGEB) and Pars Hospital Laboratory of Tehran, Iran on 96 diabetic patients urine samples. First, anti human albumin antibodies (Abs) were produced in rabbit and immunoglobulin G (IgG) fraction was purified by protein-A affinity chromatography. Titer of Abs and optimum incubation conditions were tested by direct ELISA. Then different concentration of human albumin (0-300 mg/l) was loaded to nitrocellulose membranes and was assayed by dot immunoblotting method. The specificity and cross reactivity of Abs was tested by SDS-PAGE electrophoresis and western immunoblotting. The sensitivity of the method was calculated from human albumin calibration curve and compared with commercial immunoturbidimetric assays. Our results indicates that in using IgG with the concentrations 0.5-1 ug/ml (2 x 10-5 to 10-4 dilutions) the intensity of color directly increased with the increase of human albumin standards in blots. Western immunoblotting of urine samples did not show any cross reactivity with other urine proteins. Comparison of results of this method by commercial immunoturbidimetric methods indicates the correlation regression of approximately 0.979. The sensitivity of the method was approximately 5 mg/L of human albumin. This simple

    While concerns remain regarding Electronic Medical Records (EMR) use impeding doctor-patient communication, resident and faculty patient perspectives post-widespread EMR adoption remain largely unexplored. We aimed to describe patient perspectives of outpatient resident and faculty EMR use and identify positive and negative EMR use examples to promote optimal utilization. This was a prospective mixed-methods study. Internal medicine faculty and resident patients at the University of Chicago's primary care clinic participated in the study. In 2013, one year after EMR implementation, telephone interviews were conducted with patients using open-ended and Likert style questions to elicit positive and negative perceptions of EMR use by physicians. Interview transcripts were analyzed qualitatively to develop a coding classification. Satisfaction with physician EMR use was examined using bivariate statistics. In total, 108 interviews were completed and analyzed. Two major themes were noted: (1) Clinical Functions of EMR and (2) Communication Functions of EMR; as well as six subthemes: (1a) Clinical Care (i.e., clinical efficiency), (1b) Documentation (i.e., proper record keeping and access), (1c) Information Access, (1d) Educational Resource, (2a) Patient Engagement and (2b) Physical Focus (i.e., body positioning). Overall, 85 % (979/1154) of patient perceptions of EMR use were positive, with the majority within the "Clinical Care" subtheme (n = 218). Of negative perceptions, 66 % (115/175) related to the "Communication Functions" theme, and the majority of those related to the "Physical Focus" subtheme (n = 71). The majority of patients (90 %, 95/106) were satisfied with physician EMR use: 59 % (63/107) reported the computer had a positive effect on their relationship and only 7 % (8/108) reported the EMR made it harder to talk with their doctors. Despite concerns regarding EMRs impeding doctor-patient communication, patients reported largely positive

    Full Text Available Background: Despite the availability of a  large number of treatments for multiple sclerosis with various targets, these treatments are not always effective. According to the literature, experimental studies have shown a  significant decrease in tumor necrosis factor alfa (TNF-α with the use of extracorporeal photochemotherapy. Aim: To assess changes in TNF-α in patients with multiple sclerosis during treatment with transimmunization. Materials and methods: The study recruited 13 adult patients with multiple sclerosis. Serum TNF-α was measured by immunochemiluminescence analysis (IMMULITE 1000, Siemens. The patients were treated by transimmunization, i.e. a  modified photopheresis. Two hours before the procedure, Ammifurin (8-methoxypsoralene was administered to all the patients, then their mononuclear cells were isolated under PBSC protocol with Haemonetics MCS+ cell separator. Thereafter, mononuclear cells were irradiated with ultraviolet for 90  minutes and incubated for 20 hours at 37 °С. The next day the cells were re-infused to the patients. The procedure was performed 2  times per week for 6  months, then once per 4  months. Results: Before transimmunization, mean TNF-α level in adult patients with multiple sclerosis was 9.958±0.812  pg/mL (normal, below 8.1 pg/mL. After transimmunization, its level was 6.992±0.367  pg/mL (р<0.05. Conclusion: Ultraviolet irradiation of peripheral blood monocytes with their subsequent incubation (transimmunization led to a 30% decrease of serum TNF-α in patients with multiple sclerosis. This indicates a suppressive effect of transimmunization on TNF-α. Hence, in patients with multiple sclerosis transimmunization exerts an anti-inflammatory effect.

    Full Text Available Abstract Background A medication information intervention was delivered to patients with a major depressive episode prior to psychiatric hospital discharge. Methods The objective of this study was to explore how patients evolved after hospital discharge and to identify factors influencing this evolution. Using a quasi-experimental longitudinal design, the quantitative analysis measured clinical (using the Hospital Anxiety and Depression Scale, the somatic dimension of the Symptom Checklist 90 and recording the number of readmissions and humanistic (using the Quality of Life Enjoyment and Satisfaction Questionnaire outcomes of patients via telephone contacts up to one year following discharge. The qualitative analysis was based on the researcher diary, consisting of reports on the telephone outcome assessment of patients with major depression (n = 99. All reports were analyzed using the thematic framework approach. Results The change in the participants' health status was as diverse as it was at hospital discharge. Participants reported on remissions; changes in mood; relapses; and re-admissions (one third of patients. Quantitative data on group level showed low anxiety, depression and somatic scores over time. Three groups of contributing factors were identified: process, individual and environmental factors. Process factors included self caring process, medical care after discharge, resumption of work and managing daily life. Individual factors were symptom control, medication and personality. Environmental factors were material and social environment. Each of them could ameliorate, deteriorate or be neutral to the patient's health state. A mix of factors was observed in individual patients. Conclusions After hospital discharge, participants with a major depressive episode evolved in many different ways. Process, individual and environmental factors may influence the participant's health status following hospital discharge. Each of the factors

    Management of dementia is very crucial. Nonpharmacological methods (NPM) are well appreciated and encouraged to be used as first-line treatment for managing elderly patients with dementia (PwD). The present case reports aimed to share the strategies of NPM for managing PwD. NPM requires a structured blueprint to record, follow-up, and monitor the outcomes. A structured proforma has been developed in the department. After getting all the basic information from the patient, needed assessments are being done by the concerned team member to identify and rate the level of severity of the problem, and specific NPM strategies are being provided. Concerted efforts give positive results; knowledge and understanding about the illness help the caregiver in managing the patient. No negative impact has been reported; NPM is a cost-effective approach and therefore should be studied on a larger level to provide evidence from India and prove its efficacy.

    To investigate the effect of general or regional anesthesia on postoperative cardiopulmonary complications and inpatient mortality after hip fracture surgery in elderly patients. A retrospective analysis was conducted according to the medical records of 572 elderly patients with hip fractures admitted to our hospital from January 1, 2005 to December 31, 2014. The age, gender, preoperative comorbidities, length of preoperative bedridden time, mechanism of injury, surgical types, anesthetic methods, major postoperative complications and inpatient mortality were recorded. Multivariate Logistic regression analysis was applied to analyze the impact of different anesthetic methods on inpatient mortality in these patients. Of the 572 patients, 392 (68.5%) received regional anesthesia. Inpatient death occurred in 8 (8/572, mortality: 1.4%), including 5 cases of RA group (5/392, mortality: 1.3%) and 3 cases of GA group (3/180, mortality: 1.7%). There was no statistically significant difference between the two groups in inpatient mortality (P>0.05). Multiple Logistic regression analysis showed that gender (odds ratio: 0.18, 95% CI: 0.03-1.05, P=0.057), age (odds ratio: 1.22, 95% CI: 1.07-1.38, P=0.002), preoperative pulmonary comorbidities (odds ratio: 12.09, 95% CI: 2.28-64.12, P=0.003) and surgical types (odds ratio: 9.36, 95% CI: 1.34-64.26, P=0.024) were risk factors for inpatient mortality. Postoperative cardiovascular complications occurred in 36 patients (36/572, morbidity: 6.3%), with 19 patients in RA group (19/392, morbidity: 4.8%),and 17 patients in GA group (17/180, morbidity: 9.4%). Multiple Logistic regression analysis showed that age (odds ratio: 1.13, 95% CI: 1.07-1.19, Pbedridden time (odds ratio: 1.11, 95% CI: 1.04-1.18, P=0.003) and anesthetic methods (odds ratio: 5.86, 95% CI: 2.98-11.53, Pelderly patients.

    Control of hydration status is an important constituent of adequate and efficient hemodialysis (HD) treatment. Nevertheless, there are no precise clinical indices for early recognition of small changes in fluid status of patients undergoing chronic hemodialysis therapy. This study aimed to evaluate and compare the widely used and reliable method of indexed inferior vena cava diameter (IVCDi) with established and more recently available techniques (bioelectrical impedance analysis [BIA], continuous blood volume monitoring [Crit-line], and the B-line score [BLS] with lung ultrasonography) for estimating the hydration status of patients on HD. Fifty-three patients undergoing chronic HD thrice weekly were included in the study. Evaluation of hydration status methods (IVCDi, BLS, BIA, and Crit-line) was performed thrice weekly before and after HD. Receiver operating characteristic curve analysis was performed to evaluate the discriminative power of (methods) the BLS, BIA, and Crit-line for predicting over- and underhydration of patients, as determined by the reference method, IVCDi. BLS showed the most promising results in predicting overhydration, as determined by IVCDi, compared with BIA and Crit-line and presented a sensitivity of 77% and specificity of 74%. The accuracy of the BLS was higher than that of BIA (0.81 vs. 0.71, p = 0.032) and Crit-line (0.61, p = 0.001). BLS also showed more promising results in predicting underhydration, as determined by IVCDi, than BIA and Crit-line and presented a sensitivity of 78% and a specificity of 73%. The accuracy of the BLS was higher than that of BIA (0.83 vs. 0.76, p = 0.035) and Crit-line (0.50, p < 0.001). The BLS is a useful and easily performed technique that has recently become available for accurate evaluation of dry weight and fluid status in patients with end-stage renal disease undergoing chronic HD. This method might help recognize asymptomatic lung congestion in these patients.

Methods: In this observational prospective study, 237 patients were recruited from the intensive care unit of Imam Ali Hospital of Kermanshah. The patients’ body temperatures were measured by four peripheral methods; oral, axillary, tympanic, and forehead along with a standard central nasopharyngeal measurement. After data collection, the results were analyzed by paired t-test, kappa coefficient, receiver operating characteristic curve, and using Statistical Package for the Social Sciences, version 19, software. Results: There was a significant meaningful correlation between all the peripheral methods when compared with the central measurement (P<0.001. Kappa coefficients showed good agreement between the temperatures of right and left tympanic membranes and the standard central nasopharyngeal measurement (88%. Paired t-test demonstrated an acceptable precision with forehead (P=0.132, left (P=0.18 and right (P=0.318 tympanic membranes, oral (P=1.00, and axillary (P=1.00 methods. Sensitivity and specificity of both the left and right tympanic membranes were more than for other methods. Conclusion: The tympanic and forehead methods had the highest and lowest accuracy for measuring body temperature, respectively. It is recommended to use the tympanic method (right and left for

    The use of dental radiographic examinations is common although radiation dose resulting from the dental radiography is relatively small. Therefore, it is required to evaluate radiation dose from the dental radiography for radiation safety purpose. The objectives of the present study were to develop dosimetry method for intraoral dental radiography using a Monte Carlo method based radiation transport code and to calculate organ doses and effective doses of patients from different types of intraoral radiographies. Radiological properties of dental radiography equipment were characterized for the evaluation of patient radiation dose. The properties including x-ray energy spectrum were simulated using MCNP code. Organ doses and effective doses to patients were calculated by MCNP simulation with computational adult phantoms. At the typical equipment settings (60 kVp, 7 mA, and 0.12 sec), the entrance air kerma was 1.79 mGy and the measured half value layer was 1.82 mm. The half value layer calculated by MCNP simulation was well agreed with the measurement values. Effective doses from intraoral radiographies ranged from 1 μSv for maxilla premolar to 3 μSv for maxilla incisor. Oral cavity layer (23⁓82 μSv) and salivary glands (10⁓68 μSv) received relatively high radiation dose. Thyroid also received high radiation dose (3⁓47 μSv) for examinations. The developed dosimetry method and evaluated radiation doses in this study can be utilized for policy making, patient dose management, and development of low-dose equipment. In addition, this study can ultimately contribute to decrease radiation dose to patients for radiation safety

    Background: The present study aimed to evaluate the different methods for removing oral biofilm in combination with 0.12% chlorhexidine, in patients admitted to the intensive care unit (ICU) of the General University Hospital. Materials and Methods: Initially, the patients were included in the study and underwent periodontal evaluation by means of the visible plaque index (VPI) and gingival bleeding index (GBI). The removal of visible biofilm, by a professional, was carried out using a toothbrush and dental floss, followed by the application of a 0.12% chlorhexidine solution. The patients were included in this randomized and controlled study into four groups (total n = 48), as follows: Chlorhexidine and gauze 12/12 h; chlorhexidine and gauze 24/24 h; chlorhexidine and brushing 12/12 h; chlorhexidine and brushing 24/24 h. The patients underwent the biofilm removal protocol for 7 days and then were subjected to a new clinical evaluation as to VPI and GBI. Data analysis was performed through stratification and arrangement of the records, in order to carry out the associations with health indicators used in the study, and the statistical tests used were Kappa and t-test for independent and paired samples. Results: A decrease in the VPI and GBI values when comparing baseline to the final evaluation for all groups was observed. Conclusion: Based on the methodology, it was possible to concluded that chlorhexidine associated with the mechanical action of the toothbrush or gauze in the times 12 h and 24 h in the ICU environment presented the same results as regards amount of visible biofilm.

    To study the methods used for the termination of pregnancy and associated complications of induced abortion. This descriptive study was conducted in the department of obstetrics and gynaecology, Fauji Foundation Hospital Rawalpindi. One Hundred patients were included in the study who was admitted with the history of induced abortion. The patients were assessed by detailed history and thorough clinical examination according to the study protocol. Data was collected on a specially designed Performa. Patients were interviewed in privacy and factors contributing to termination of pregnancy like age, parity, socioeconomic status and contraceptive failure were determined. Methods used for the procedure, status of abortionist were asked. Complications were determined by history, clinical examination and ultrasound examination. In view of all above data recommendations of preventing unwanted pregnancies were made. All patients were married and 57% of women belonged to age group of 31-40 years. Fifty-four 54% were grand multipara. In 63% of patients, induced abortion was carried out by Dai's. Most commonly used method was instrumentation (72%). Financial problems (46.7% ) and high parity (40%) were the most common factors contributing to termination of pregnancy. Serious complications like uterine perforation with or without bowel injury were accounted in 13% of women, septicaemia in 61%, peritonitis in 15% and DIC in 2%. During the study period illegally induced abortion accounted for 2% maternal deaths. Prevalence of poverty, illiteracy, grand multiparity and non-compliance of contraception were strong determinants of induced abortion, instrumentation being the most commonly used procedure resulting in high morbidity and mortality.

    Targeted temperature management post-cardiac arrest is currently implemented using various methods, broadly categorized as internal and external. This study aimed to evaluate survival-to-hospital discharge and neurological outcomes (Glasgow-Pittsburgh Score) of post-cardiac arrest patients undergoing internal cooling verses external cooling. A randomized controlled trial of post-resuscitation cardiac arrest patients was conducted from October 2008-September 2014. Patients were randomized to either internal or external cooling methods. Historical controls were selected matched by age and gender. Analysis using SPSS version 21.0 presented descriptive statistics and frequencies while univariate logistic regression was done using R 3.1.3. 23 patients were randomized to internal cooling and 22 patients to external cooling and 42 matched controls were selected. No significant difference was seen between internal and external cooling in terms of survival, neurological outcomes and complications. However in the internal cooling arm, there was lower risk of developing overcooling (p=0.01) and rebound hyperthermia (p=0.02). Compared to normothermia, internal cooling had higher survival (OR=3.36, 95% CI=(1.130, 10.412), and lower risk of developing cardiac arrhythmias (OR=0.18, 95% CI=(0.04, 0.63)). Subgroup analysis showed those with cardiac cause of arrest (OR=4.29, 95% CI=(1.26, 15.80)) and sustained ROSC (OR=5.50, 95% CI=(1.64, 20.39)) had better survival with internal cooling compared to normothermia. Cooling curves showed tighter temperature control for internal compared to external cooling. Internal cooling showed tighter temperature control compared to external cooling. Internal cooling can potentially provide better survival-to-hospital discharge outcomes and reduce cardiac arrhythmia complications in carefully selected patients as compared to normothermia.

    Successful treatment of diabetes includes patient self-management behaviors to prevent or delay complications and comorbid diseases. On the basis of findings from large clinical trials and professional guidelines, diabetes education programs and health providers prescribe daily regimens of glucose monitoring, healthy eating, stress management, medication adherence, and physical activity. Consistent, long-term commitment to regimens is challenging. Mobile health is increasingly being used to assist patients with lifestyle changes and self-management behaviors between provider visits. The effectiveness of mobile health to improve diabetes outcomes depends on patient engagement with a technology, content, or interactions with providers. In the current analysis, we aimed to identify patient engagement themes in diabetes messaging with diabetes providers and determine if differences in engagement in the Mobile Diabetes Intervention Study (MDIS) influenced changes in glycated hemoglobin A 1c (HbA 1c ) over a 1-year treatment period (1.9% absolute decrease in the parent study). In the primary MDIS study, 163 patients were enrolled into 1 of 3 mobile intervention groups or a usual care control group based on their physician cluster randomization assignment. The control group received care from their physicians as usual. Participants in each intervention group had access to a patient portal where they could record monitoring values for blood glucose, blood pressure, medication changes, or other self-management information while also assigned to varying levels of physician access to patient data. Intervention participants could choose to send and receive messages to assigned certified diabetes educators with questions or updates through the secure Web portal. For this secondary analysis, patient engagement was measured using qualitative methods to identify self-care themes in 4109 patient messages. Mixed methods were used to determine the impact of patient engagement on

Most nurses prescribed weight control (72.1%, diet control (76.7%, patient education (74.4%, and life-style modification (72.1%. Most (83.7% nurses were aware of exercise as a treatment method for hypertension. Only seven nurses, prescribing a brisk walk, recommended the correct type of exercise. The nurses’attitude towards exercise as a treatment method was determined using focus group interviews (n=16. Nurses reflected a positive attitude towards exercise with 198 positive responses. Nurses could express more than one opinion, all of which were recorded. Twenty responses reflected little or no knowledge, and four responses reflected an unsure/neutral attitude towards exercise. Ten responses reflected disinterest in prescribing exercise. Nurses do not have adequate knowledge to enable them to confidently prescribe exercise to patients. The need for more information was mentioned and some nurses were willing to present exercise classes. A training program, containing pertinent information, so that nurses can prescribe exercise for hypertension, needs to be developed.

    To assess the utility of hysterosonography (HS) as a screening method in patients with abnormal uterine bleeding. We retrospectively reviewed transvaginal ultrasonography (TVS) and HS for 105 patients whose diagnosis was confirmed pathologically. All 105 patients were initially evaluated on the same day with both TVS and HS. On TVS and HS examination. endometrial cavitary lesions were classified as diffuse hyperplasis, endometrial polyp, endometrial cancer, uterine synechia and submucosal leiomyoma. Hysteroscopy with biopsy (n=35), curettage (n=60) or hysterectomy (n=10) was performed, and the results of TVS and HS examination were correlated with the pathological findings. The sensitivity and specificity were 79.0% and 45.8% for TVS, and 95.1% and 83.3% for HS, respectively. The positive and negative predictive values were 83.0% and 39.3% for TVS, and 95.1% and 83.3% for HS, respectively. Twenty-seven showed a discrepancy between the TVS and HS, and eight cases showed a discrepancy between HS and the pathologic diagnosis. TVS is a sensitive method to evaluate the endometrial cavitary lesions, but it often does not provide the physician with sufficient diagnostic information. With its higher sensitivities, specificities and positive and negative predictive values, HS can be better used than TVS in evaluating those patients with abnormal uterine bleeding

    To review the literature and investigate the meaning of hope to patients receiving palliative care and to examine the themes that foster hope in those patients. Hope is often linked to the future and is a significant factor for patients dealing with adversity, such as a terminal illness. The concept of hope is underreported in the literature. Mixed method thematic review. CINAHL, Scopus, PsychINFO, Informit, PubMed, Science Direct, ProQuest, Web of Science and Google Scholar online databases were searched using keywords and inclusion and exclusion criteria published between 2003-2013. Twelve qualitative articles were thematically analysed using Braun and Clarke's (2006) steps to ascertain major themes and sub-themes. On analysis, the remaining three mixed method studies were found to reflect the themes generated by the qualitative studies. Seven key themes that increased hope were found: disease status; positive personal relationships; positive character traits; quality of life; setting and achieving goals; spirituality/religion; and hope after death. The importance of hope to dying patients was established. Hope is a very complex and personal phenomena requiring hope-enhancing strategies to be individualized. More research is needed with groups whose culture, youth or type of illness may affect their ability to foster and maintain hope. © 2015 John Wiley & Sons Ltd.

    Research in patient safety is an important area of health services research and is a national priority. It is challenging to investigate rare occurrences, explore potential causes, and account for the complex, dynamic context of healthcare - yet all are required in patient safety research. Simulation technologies have become widely accepted as education and clinical tools, but have yet to become a standard tool for research. We developed a framework for research that integrates accepted patient safety models with mixed-methods research approaches and describe the performance of the framework in a working example of a large National Institutes of Health (NIH)-funded R01 investigation. This worked example of a framework in action, identifies the strengths and limitations of qualitative and quantitative research approaches commonly used in health services research. Each approach builds essential layers of knowledge. We describe how the use of simulation ties these layers of knowledge together and adds new and unique dimensions of knowledge. A mixed-methods research approach that includes simulation provides a broad multi-dimensional approach to health services and patient safety research.

    Heart rate variability (HRV) is an important indicator of autonomic modulation of cardiovascular function. Diabetes can alter cardiac autonomic modulation by damaging afferent inputs, thereby increasing the risk of cardiovascular disease. We applied nonlinear analytical methods to identify parameters associated with HRV that are indicative of changes in autonomic modulation of heart function in diabetic patients. We analyzed differences in HRV patterns between diabetic and age-matched healthy control subjects using nonlinear methods. Lagged Poincaré plot, autocorrelation, and detrended fluctuation analysis were applied to analyze HRV in electrocardiography (ECG) recordings. Lagged Poincare plot analysis revealed significant changes in some parameters, suggestive of decreased parasympathetic modulation. The detrended fluctuation exponent derived from long-term fitting was higher than the short-term one in the diabetic population, which was also consistent with decreased parasympathetic input. The autocorrelation function of the deviation of inter-beat intervals exhibited a highly correlated pattern in the diabetic group compared with the control group. The HRV pattern significantly differs between diabetic patients and healthy subjects. All three statistical methods employed in the study may prove useful to detect the onset and extent of autonomic neuropathy in diabetic patients.

We applied nonlinear analytical methods to identify parameters associated with HRV that are indicative of changes in autonomic modulation of heart function in diabetic patients. We analyzed differences in HRV patterns between diabetic and age-matched healthy control subjects using nonlinear methods. Lagged Poincaré plot, autocorrelation, and detrended fluctuation analysis were applied to analyze HRV in electrocardiography (ECG) recordings. Lagged Poincare plot analysis revealed significant changes in some parameters, suggestive of decreased parasympathetic modulation. The detrended fluctuation exponent derived from long-term fitting was higher than the short-term one in the diabetic population, which was also consistent with decreased parasympathetic input. The autocorrelation function of the deviation of inter-beat intervals exhibited a highly correlated pattern in the diabetic group compared with the control group. The HRV pattern significantly differs between diabetic patients and healthy subjects. All three statistical methods employed in the study may prove useful to detect the onset and extent of autonomic neuropathy in diabetic patients

    The aims of this systematic integrative review were to identify evidence for the use of patient simulation teaching methods in pharmacotherapy education and to explore related learning outcomes. A systematic literature search was conducted using 6 databases as follows: CINAHL, PubMed, SCOPUS, ERIC, MEDIC, and the Cochrane Library, using the key words relating to patient simulation and pharmacotherapy. The methodological quality of each study was evaluated. Eighteen articles met the inclusion criteria. The earliest article was published in 2005. The selected research articles were subjected to qualitative content analysis. Patient simulation has been used in pharmacotherapy education for preregistration nursing, dental, medical, and pharmacy students and for the continuing education of nurses. Learning outcomes reported were summarized as follows: (1) commitment to pharmacotherapy learning, (2) development of pharmacotherapy evaluation skills, (3) improvement in pharmacotherapy application skills, and (4) knowledge and understanding of pharmacotherapy. To develop effective teaching methods and ensure health care professionals' competence in medication management, further research is needed to determine the educational and clinical effectiveness of simulation teaching methods.

    Objective: To investigate the alternations in regional cerebral blood flow (rCBF) in obsessive compulsive disorder (OCD) patients using statistical parametric mapping (SPM). Methods: rCBF measurements using 99 Tc m -ethyl cysteinate dimer (ECD) SPECT was performed on 14 OCD patients and 23 age-matched healthy volunteers. The rCBF distribution was compared between these two groups with SPM under the conditions of increased and decreased perfusion, and with regions of interest (ROIs) using cerebral template. P value was set at 0.01 level. Results: SPM analysis showed that rCBF decreased in cerebral areas including bilateral putamen, superior temporal gyrus and precuneus, and right orbital gyrus, superior and middle frontal gyrus, and left temporo-occipital lobule and superior parietal gyrus, and vermis. rCBF was also increased in left inferior frontal gyrus and posterior cingulate gyrus. With ROIs method, rCBF was decreased in right anterior frontal, temporo-parietal lobule and left temporo-occipital lobule. Conclusions: The study supports the viewpoint that rCBF abnormality of fronto-striatal circuits is involved in OCD patients. SPM method is a forceful tool in analyzing cerebral regional characters

    Full text: A system for patient set-up in external beam radiotherapy was developed using Augmented Reality (AR). Live images of the linac treatment couch and patient were obtained with video cameras and displayed on a nearby monitor. A 3D model of the patient's external contour was obtained from planning CT data, and AR tracking software was used to superimpose the model onto the video images in the correct position for treatment. Throughout set-up and treatment, the user can view the monitor and visually confirm that the patient is positioned correctly. To ensure that the virtual contour was displayed in the correct position, a process was devised to register the coordinates of the linac with the camera images. A cube with AR tracking markers attached to its faces was constructed for alignment with the isocentre using room lasers or cone-beam CT. The performance of the system was investigated in a clinical environment by using it to position an anthropomorphic phantom without the aid of additional set-up methods. The positioning errors were determined by means of CBCT and image registration. The translational set-up errors were found to be less than 2.4 mm and the rotational errors less than 0.3 0 . This proof-of-principle study has demonstrated the feasibility of using AR for patient position and pose guidance.

    A recently described technique proposes a simple method to achieve permanent hemostasis of distal fingertip dermal avulsion injuries. It is simple to learn and easy to perform with readily available materials found in most emergency departments. However, long-term outcomes for patients treated with this technique have not yet been evaluated. A primary objective of the current article is to provide safety data for the technique using an off-label product indication. Emergency department of Kaiser Permanente Medical Center, San Francisco, California. Six patients were treated in the emergency department for fingertip dermal avulsion injuries using a tourniquet and tissue adhesive glue (Dermabond by Ethicon, Somerville, New Jersey). Patients were subsequently contacted to assess healing and satisfaction with cosmetic outcome through interview and photographs of their wounds at 9 months following the date of injury. All 6 patients were satisfied with the cosmetic outcome of treatment, and none received a diagnosis of serious complications. This series demonstrates cosmetic outcomes for injuries treated with the technique, highlights potential problems that may be perceived by patients during their clinical course, and creates the groundwork for a larger clinical study examining the use of the technique.

    Dental hygiene educators must determine which educational practices best promote critical thinking, a quality necessary to translate knowledge into sound clinical decision making. The aim of this small pilot study was to determine whether virtual patient simulation had an effect on the critical thinking of dental hygiene students. A pretest-posttest design using the Health Science Reasoning Test was used to evaluate the critical thinking skills of senior dental hygiene students at The University of Texas School of Dentistry at Houston Dental Hygiene Program before and after their experience with computer-based patient simulation cases. Additional survey questions sought to identify the students' perceptions of whether the experience had helped develop their critical thinking skills and improved their ability to provide competent patient care. A convenience sample of 31 senior dental hygiene students completed both the pretest and posttest (81.5% of total students in that class); 30 senior dental hygiene students completed the survey on perceptions of the simulation (78.9% response rate). Although the results did not show a significant increase in mean scores, the students reported feeling that the use of virtual patients was an effective teaching method to promote critical thinking, problem-solving, and confidence in the clinical realm. The results of this pilot study may have implications to support the use of virtual patient simulations in dental hygiene education. Future research could include a larger controlled study to validate findings from this study.

    Text messaging has become more prevalent in general practice as a tool with which to communicate with patients. The main objectives were to assess the extent, growth, and perceived risks and benefits of text messaging by GPs to communicate with patients, and assess patients' attitudes towards receiving text messages from their GP. A mixed methods study, using surveys, a review, and a focus group, was conducted in both urban and rural practices in the south-west of Ireland. A telephone survey of 389 GPs was conducted to ascertain the prevalence of text messaging. Subsequently, the following were also carried out: additional telephone surveys with 25 GPs who use text messaging and 26 GPs who do not, a written satisfaction survey given to 78 patients, a review of the electronic information systems of five practices, and a focus group with six GPs to ascertain attitudes towards text messaging. In total, 38% ( n = 148) of the surveyed GPs used text messaging to communicate with patients and 62% ( n = 241) did not. Time management was identified as the key advantage of text messaging among GPs who used it (80%; n = 20) and those who did not (50%; n = 13). Confidentiality was reported as the principal concern among both groups, at 32% ( n = 8) and 69% ( n = 18) respectively. Most patients (99%; n = 77) were happy to receive text messages from their GP. The GP focus group identified similar issues and benefits in terms of confidentiality and time management. Data were extracted from the IT systems of five consenting practices and the number of text messages sent during the period from January 2013 to March 2016 was generated. This increased by 40% per annum. Collaborative efforts are required from relevant policymakers to address data protection and text messaging issues so that GPs can be provided with clear guidelines to protect patient confidentiality. © British Journal of General Practice 2017.

    Effective communication between pharmacists and patients is a crucial factor in ensuring that medications are used properly. However, few studies have examined the contents of actual on-site communications between pharmacists and patients. To identify the characteristics of and problems with routine communications between pharmacists and patients using the Roter Method of Interaction Process Analysis System (RIAS). Conversations between pharmacists and simulated patients (SPs) were recorded and transcribed. Using the RIAS technique, their utterances were classified into 42 categories, and these were further divided into 11 clusters, such as open- and closed-ended questions, and analyzed. Furthermore, the influence that the different scenarios performed by the pharmacists may have had on the structure of their communication was investigated. All of the transcripts were double-coded by two certified coders. A total of 57 pharmacists took part in the study. The mean ratio of utterances made by SPs and pharmacists were 44% and 56%, respectively. The percentage of pharmacists' questions was more than double that of SPs' for both open- and closed-ended questions. In the influence that the different scenarios, the scenarios for patients with cancer was significantly higher ratio of utterances by the pharmacists. Pharmacists' communications tended to focus more on information-gathering activities that concentrated on closed-ended questions and frequent counseling, or directing utterances about the medication than on considering the patient's background. On the other hand, the pharmacists did communicate in ways that matched each patient's disease. This study identified the structure of pharmacists' on-site communications, and revealed the associated characteristics and problems. Copyright © 2016 Elsevier Inc. All rights reserved.

    Several factors are involved in the pathogenesis of dialysis discomfort interfering with optimal fluid removal and reducing the efficacy of the treatment; the most important one is a decrease in blood volume caused by an imbalance between ultrafiltration (UF) and plasmarefilling (PR) rates. This study is aimed at devising a method to tailor the dialysis therapy to each individual patient, by analyzing the relationship between PR and UF during the sessions in stable patients and widening the knowledge of fluid exchanges during the treatment. Thirty stable patients undergoing maintenance hemodialysis were enrolled. Three dialysis sessions were monitored for each patient; systemic pressure, blood composition, blood volume % variation, weight loss and conductivity were recorded repeatedly. A Plasma Refilling Index (PRI), defined and calculated by means of parameters measured throughout the dialysis, was introduced as a novel instrument to study plasma refilling phenomena. Results. The PRI provides understanding of patient response (in terms of plasma refilling) to the set UF. In the monitored sessions, the PRI trend is found to be characteristic of each patient; a PRI course that is at variance with the characteristic trend is a signal of inadequate or unusual dialysis scheduling. Moreover, statistical analysis highlights two different PRI trends during the first hour and during the rest of the treatment, suggesting the presence of different treatment phases. The main advantage of the PRI index is that it is non-invasive peculiar to each patient and easy to compute in a dialysis routine based on online data recorded by the monitor. A deviation from the characteristic trend may be a warning for the clinician. The analysis of the PRI trend also suggests how to modulate UF as a function of interstitial to intravascular fluid removal balance during dialysis.

    Modern health systems are increasingly faced with the challenge to provide effective, affordable and accessible health care for people with chronic conditions. As evidence on the specific unmet needs and their impact on health outcomes is limited, practical research is needed to tailor chronic care to individual needs of patients with diabetes. Qualitative approaches to describe professional and informal caregiving will support understanding the complexity of chronic care. Results are intended to provide practical recommendations to be used for systematic implementation of sustainable chronic care models. A mixed method study was conducted. A standardised survey (n = 92) of experts in chronic care using mail responses to open-ended questions was conducted to analyse existing chronic care programs focusing on effective, problematic and missing components. An expert workshop (n = 22) of professionals and scientists of a European funded research project MANAGE CARE was used to define a limited number of unmet needs and priorities of elderly patients with type 2 diabetes mellitus and comorbidities. This list was validated and ranked using a multilingual online survey (n = 650). Participants of the online survey included patients, health care professionals and other stakeholders from 56 countries. The survey indicated that current care models need to be improved in terms of financial support, case management and the consideration of social care. The expert workshop identified 150 patient needs which were summarised in 13 needs dimensions. The online survey of these pre-defined dimensions revealed that financial issues, education of both patients and professionals, availability of services as well as health promotion are the most important unmet needs for both patients and professionals. The study uncovered competing demands which are not limited to medical conditions. The findings emphasise that future care models need to focus stronger on individual patient needs and

    Full Text Available Abstract Background Deceased donor kidneys are a scarce health resource, yet patient preferences for organ allocation are largely unknown. The aim of this study was to determine patient preferences for how kidneys should be allocated for transplantation. Methods Patients on dialysis and kidney transplant recipients were purposively selected from two centres in Australia to participate in nominal/focus groups in March 2011. Participants identified and ranked criteria they considered important for deceased donor kidney allocation. Transcripts were thematically analysed to identify reasons for their rankings. Results From six groups involving 37 participants, 23 criteria emerged. Most agreed that matching, wait-list time, medical urgency, likelihood of surviving surgery, age, comorbidities, duration of illness, quality of life, number of organs needed and impact on the recipient's life circumstances were important considerations. Underpinning their rankings were four main themes: enhancing life, medical priority, recipient valuation, and deservingness. These were predominantly expressed as achieving equity for all patients, or priority for specific sub-groups of potential recipients regarded as more "deserving". Conclusions Patients believed any wait-listed individual who would gain life expectancy and quality of life compared with dialysis should have access to transplantation. Equity of access to transplantation for all patients and justice for those who would look after their transplant were considered important. A utilitarian rationale based on maximizing health gains from the allocation of a scarce resource to avoid "wastage," were rarely expressed. Organ allocation organisations need to seek input from patients who can articulate preferences for allocation and advocate for equity and justice in organ allocation.

    The NHS has a target of cutting its carbon dioxide (CO2) emissions by 80% below 1990 levels by 2050. Travel comprises 17% of the NHS carbon footprint. This carbon footprint represents the total CO2 emissions caused directly or indirectly by the NHS. Patient journeys have previously been planned largely without regard to the environmental impact. The potential contribution of 'avoidable' journeys in primary care is significant. To investigate the carbon footprint of patients travelling to and from a general practice surgery, the issues involved, and potential solutions for reducing patient travel. A mixed methods study in a medium-sized practice in Yorkshire. During March 2012, 306 patients completed a travel survey. GIS maps of patients' travel (modes and distances) were produced. Two focus groups (12 clinical and 13 non-clinical staff) were recorded, transcribed, and analysed using a thematic framework approach. The majority (61%) of patient journeys to and from the surgery were made by car or taxi; main reasons cited were 'convenience', 'time saving', and 'no alternative' for accessing the surgery. Using distances calculated via ArcGIS, the annual estimated CO2 equivalent carbon emissions for the practice totalled approximately 63 tonnes. Predominant themes from interviews related to issues with systems for booking appointments and repeat prescriptions; alternative travel modes; delivering health care; and solutions to reducing travel. The modes and distances of patient travel can be accurately determined and allow appropriate carbon emission calculations for GP practices. Although challenging, there is scope for identifying potential solutions (for example, modifying administration systems and promoting walking) to reduce 'avoidable' journeys and cut carbon emissions while maintaining access to health care.

    Full Text Available A bioanalytical method was developed and applied to quantify the free imipenem concentrations for pharmacokinetics and PK/PD correlation studies of the dose adjustments required to maintain antimicrobial effectiveness in pediatric burn patients. A reverse-phase Supelcosil LC18 column (250 x 4.6 mm 5 micra, binary mobile phase consisting of 0.01 M, pH 7.0 phosphate buffer and acetonitrile (99:1, v/v, flow rate of 0.8 mL/min, was applied. The method showed good absolute recovery (above 90%, good linearity (0.25-100.0 µg/mL, r2=0.999, good sensitivity (LLOQ: 0.25 µg/mL; LLOD: 0.12 µg/mL and acceptable stability. Inter/intraday precision values were 7.3/5.9%, and mean accuracy was 92.9%. A bioanalytical method was applied to quantify free drug concentrations in children with burns. Six pediatric burn patients (median 7.0 years old, 27.5 kg, normal renal function, and 33% total burn surface area were prospectively investigated; inhalation injuries were present in 4/6 (67% of the patients. Plasma monitoring and PK assessments were performed using a serial blood sample collection for each set, totaling 10 sets. The PK/PD target attained (40%T>MIC for each minimum inhibitory concentration (MIC: 0.5, 1.0, 2.0, 4.0 mg/L occurred at a percentage higher than 80% of the sets investigated and 100% after dose adjustment. In conclusion, the purification of plasma samples using an ultrafiltration technique followed by quantification of imipenem plasma measurements using the LC method is quite simple, useful, and requires small volumes for blood sampling. In addition, a small amount of plasma (0.25 mL is needed to guarantee drug effectiveness in pediatric burn patients. There is also a low risk of neurotoxicity, which is important because pharmacokinetics are unpredictable in these critical patients with severe hospital infection. Finally, the PK/PD target was attained for imipenem in the control of sepsis in pediatric patients with burns.

    Full Text Available Introduction: Traditional medicine is a comprehensive system of theory and practice, implemented in the prevention, diagnostics and treatment of diseases, which utilizes preparations of vegetable, animal and mineral origin, as well as methods of spiritual therapy Objective: 1. To estimate how many patients in primary care use traditional medicine for diagnostics, treatment and prevention of diseases, and to establish possible differences regarding gender, age and urban or rural location. 2. What methods of traditional medicine are the most often used, and for which diseases and conditions? 3. Why did the subjects opted for this type of treatment, and what was the effect of the therapy? Method: Multicentric research based on interviewing patients in five outpatient health centers in Serbia. As a survey instrument was used a questionnaire with 10 questions. Results: The study included 1157 subjects, 683 women and 474 men, mean age 60.22±14.54, The traditional medicine was used by 83.66% (79.96% males and 86.245% females. Information about the methods of traditional medicine subjects usually received from their friends and acquaintances (54.9% and the media (39.3%. There is no significant difference in the way of obtaining information in relation to gender. Information on the internet was obtained more often in subjects younger than 65 (p=0.000 and in urban population (p=0.000. The same is true for information obtained from doctor or pharmacist (p=0.003. They opted for this method because in their opinion it is less harmful and have less adverse effects (72.8%. This type of treatment patients used for treatment of muscles, bone and joint diseases - 28.5%, diseases of the heart and blood vessels -21,1 %, and for the treatment of pain 19.7%.

    Full Text Available Abstract Background The importance of achieving and maintaining an appropriate metabolic control in patients with type 1 diabetes mellitus (DM1 has been established in many studies aiming to prevent the development of chronic complications. The carbohydrate counting method can be recommended as an additional tool in the nutritional treatment of diabetes, allowing patients with DM1 to have more flexible food choices. This study aimed to evaluate the influence of nutrition intervention and the use of multiple short-acting insulin according to the carbohydrate counting method on clinical and metabolic control in patients with DM1. Methods Our sample consisted of 51 patients with DM1, 32 females, aged 25.3 ± 1.55 years. A protocol of nutritional status evaluation was applied and laboratory analysis was performed at baseline and after a three-month intervention. After the analysis of the food records, a balanced diet was prescribed using the carbohydrate counting method, and short-acting insulin was prescribed based on the total amount of carbohydrate per meal (1 unit per 15 g of carbohydrate. Results A significant decrease in A1c levels was observed from baseline to the three-month evaluation after the intervention (10.40 ± 0.33% and 9.52 ± 0.32%, respectively, p = 0.000. It was observed an increase in daily insulin dose after the intervention (0.99 ± 0.65 IU/Kg and 1.05 ± 0.05 IU/Kg, respectively, p = 0.003. No significant differences were found regarding anthropometric evaluation (BMI, waist, hip or abdominal circumferences and waist to hip ratio after the intervention period. Conclusions The use of short-acting insulin based on the carbohydrate counting method after a short period of time resulted in a significant improvement of the glycemic control in patients with DM1 with no changes in body weight despite increases in the total daily insulin doses.

    Patient-reported outcomes (PROs) promote patient-centered care by using PRO research results ("group-level data") to inform decision making and by monitoring individual patient's PROs ("individual-level data") to inform care. We investigated the interpretability of current PRO data presentation formats. This cross-sectional mixed-methods study randomized purposively sampled cancer patients and clinicians to evaluate six group-data or four individual-data formats. A self-directed exercise assessed participants' interpretation accuracy and ratings of ease-of-understanding and usefulness (0 = least to 10 = most) of each format. Semi-structured qualitative interviews explored helpful and confusing format attributes. We reached thematic saturation with 50 patients (44 % < college graduate) and 20 clinicians. For group-level data, patients rated simple line graphs highest for ease-of-understanding and usefulness (median 8.0; 33 % selected for easiest to understand/most useful) and clinicians rated simple line graphs highest for ease-of-understanding and usefulness (median 9.0, 8.5) but most often selected line graphs with confidence limits or norms (30 % for each format for easiest to understand/most useful). Qualitative results support that clinicians value confidence intervals, norms, and p values, but patients find them confusing. For individual-level data, both patients and clinicians rated line graphs highest for ease-of-understanding (median 8.0 patients, 8.5 clinicians) and usefulness (median 8.0, 9.0) and selected them as easiest to understand (50, 70 %) and most useful (62, 80 %). The qualitative interviews supported highlighting scores requiring clinical attention and providing reference values. This study has identified preferences and opportunities for improving on current formats for PRO presentation and will inform development of best practices for PRO presentation. Both patients and clinicians prefer line graphs across group-level data and individual

    Background Although early and rapid detection of histoplasmosis is essential to prevent morbidity and mortality, few diagnostic tools are available in resource-limited areas, especially where it is endemic and HIV/AIDS is also epidemic. Thus, we compared conventional and molecular methods to detect Histoplasma capsulatum in sera and blood from HIV/AIDS patients. Methodology We collected a total of 40 samples from control volunteers and patients suspected of histoplasmosis, some of whom were also infected with other pathogens. Samples were then analyzed by mycological, serological, and molecular methods, and stratified as histoplasmostic with (group I) or without AIDS (group II), uninfected (group III), and infected with HIV and other pathogens only (group IV). All patients were receiving treatment for histoplasmosis and other infections at the time of sample collection. Results Comparison of conventional methods with nested PCR using primers against H. capsulatum 18S rRNA (HC18S), 5.8S rRNA ITS (HC5.8S-ITS), and a 100 kDa protein (HC100) revealed that sensitivity against sera was highest for PCR with HC5.8S-ITS, followed by immunoblotting, double immunodiffusion, PCR with HC18S, and PCR with HC100. Specificity was equally high for double immunodiffusion, immunoblotting and PCR with HC100, followed for PCR with HC18S and HC5.8-ITS. Against blood, sensitivity was highest for PCR with HC5.8S-ITS, followed by PCR with HC18S, Giemsa staining, and PCR with HC100. Specificity was highest for Giemsa staining and PCR with HC100, followed by PCR with HC18S and HC5.8S-ITS. PCR was less efficient in patients with immunodeficiency due to HIV/AIDS and/or related diseases. Conclusion Molecular techniques may detect histoplasmosis even in cases with negative serology and mycology, potentially enabling early diagnosis. PMID:29342162

    The Eating Disorder Examination (EDE) is a well-established assessment instrument, but requires substantial training and administration time. The Eating Disorder Examination Questionnaire (EDE-Q) is the corresponding self-report survey, which does not have these demands. Research has shown concordance between these 2 assessment methods, but samples have lacked racial diversity. The current study examined the concordance of the EDE-Q and EDE in a sample of Black patients with binge-eating disorder (BED) and a matched sample of White patients. Participants were 238 (Black n = 119, White n = 119) treatment-seeking adults with DSM-IV-TR-defined BED. Participants completed the EDE-Q, and trained doctoral-level clinicians assessed participants for BED and eating-disorder psychopathology using the Structured Clinical Interview for DSM-IV Disorders and the Eating Disorder Examination (EDE) interview. The EDE-Q and EDE yielded significantly correlated frequencies of binge eating and eating-disorder psychopathology subscales. The EDE-Q yielded significantly lower frequencies of binge eating and higher scores on 3 of 4 subscales (not dietary restraint). Similar patterns of concordance between the EDE-Q and EDE were found for an alternative brief version of the instruments. Patterns of convergence and divergence between the EDE-Q and EDE observed in Black patients with BED are generally consistent with findings derived from the matched White sample: overall, scores are correlated but higher on the self-report compared with interview assessment methods. Clinicians assessing patients with BED should be aware of this overall pattern, and be aware that this pattern is similar in Black patients with BED with the notable exception of dietary restraint.

    Full Text Available We consider the analysis of an AIDS dataset where each patient is characterized by a list of symptoms and is labeled with one or more TCM syndromes. The task is to build a classifier that maps symptoms to TCM syndromes. We use the minimum reference set-based multiple instance learning (MRS-MIL method. The method identifies a list of representative symptoms for each syndrome and builds a Gaussian mixture model based on them. The models for all syndromes are then used for classification via Bayes rule. By relying on a subset of key symptoms for classification, MRS-MIL can produce reliable and high quality classification rules even on datasets with small sample size. On the AIDS dataset, it achieves average precision and recall 0.7736 and 0.7111, respectively. Those are superior to results achieved by alternative methods.

  15. Research methods to change clinical practice for patients with rare cancers.

    2016-02-01

    Rare cancers are a growing group as a result of reclassification of common cancers by molecular markers. There is therefore an increasing need to identify methods to assess interventions that are sufficiently robust to potentially affect clinical practice in this setting. Methods advocated for clinical trials in rare diseases are not necessarily applicable in rare cancers. This Series paper describes research methods that are relevant for rare cancers in relation to the range of incidence levels. Strategies that maximise recruitment, minimise sample size, or maximise the usefulness of the evidence could enable the application of conventional clinical trial design to rare cancer populations. Alternative designs that address specific challenges for rare cancers with the aim of potentially changing clinical practice include Bayesian designs, uncontrolled n-of-1 trials, and umbrella and basket trials. Pragmatic solutions must be sought to enable some level of evidence-based health care for patients with rare cancers. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Reliable identification of lower respiratory tract pathogens is crucial in the management of cystic fibrosis (CF). The multitude of treatments and clinical procedures are a considerable burden and are potentially provoking pain. As part of another study (NCT02363764), investigating the bacterial yield of three sampling methods, nasal swabs (NSs), cough swabs (CSs), and (induced) sputum samples ([I]SSs), in both expectorating patients (EPs) and non-expectorating patients (NEPs) with CF, the present study aimed to explore the prevalence of respiratory culture sampling-related pain as assessed by self-report within a cohort of children and adults. Literate patients with CF (aged six years or older) completed a questionnaire on pain perception related to the three aforementioned sampling methods (No/Yes; visual analogue scale for pain [VAS-Pain] [0-10 cm]). In addition, patients were asked to rank these methods by their own preference without taking into account the presumed bacterial yield. In total, 119 questionnaires were returned. In the EPs-group, CS was most frequently (n%; mean VAS-Pain if pain [range]) reported as painful method: overall (n = 101; 12.9%; 1.8 [0.2-4.8]), children (n = 41; 22.0%; 1.4 [0.2-2.7]), and adults (n = 60; 6.7%; 2.5 [0.5-4.8]). Highest pain intensity scores were observed with NS overall (3.0%; 2.4 [0.3-6.2]) and in children (4.9%; 3.3 [0.3-6.2]), but not in adults (1.7%; 0.6 [-]).NEPs-children (n = 17) reported ISS most frequently and as most painful sampling method (17.6%; 2.0 [1.0-4.0]). The only NEP-adult did not perceive pain. NEPs preferred NS > CS > ISS (61.1%, 33.3%, 5.6%, respectively [P = 0.001]) as primary sampling method, whereas EPs preferred SS > NS > CS (65.7%, 26.3%, 8.1%, respectively [P method inversely correlated to pain perception and intensity in EPs (φ = -0.155 [P = 0.007] and ρ = -0.926 [P = 0.008], respectively), but not in NEPs (φ = -0.226 [P = 0.097] and ρ = -0.135 [P = 0

    The combination of Positron Emission Tomography (PET) with magnetic resonance imaging (MRI) in hybrid PET/MRI scanners offers a number of advantages in investigating brain structure and function. A critical step of PET data reconstruction is attenuation correction (AC). Accounting for bone in attenuation maps (μ-map) was shown to be important in brain PET studies. While there are a number of MRI-based AC methods, no systematic comparison between them has been performed so far. The aim of this work was to study the different performance obtained by some of the recent methods presented in the literature. To perform such a comparison, we focused on [ 18 F]-Fluorodeoxyglucose-PET/MRI neurodegenerative dementing disorders, which are known to exhibit reduced levels of glucose metabolism in certain brain regions. Four novel methods were used to calculate μ-maps from MRI data of 15 patients with Alzheimer's dementia (AD). The methods cover two atlas-based methods, a segmentation method, and a hybrid template/segmentation method. Additionally, the Dixon-based and a UTE-based method, offered by a vendor, were included in the comparison. Performance was assessed at three levels: tissue identification accuracy in the μ-map, quantitative accuracy of reconstructed PET data in specific brain regions, and precision in diagnostic images at identifying hypometabolic areas. Quantitative regional errors of -20-10 % were obtained using the vendor's AC methods, whereas the novel methods produced errors in a margin of ±5 %. The obtained precision at identifying areas with abnormally low levels of glucose uptake, potentially regions affected by AD, were 62.9 and 79.5 % for the two vendor AC methods, the former ignoring bone and the latter including bone information. The precision increased to 87.5-93.3 % in average for the four new methods, exhibiting similar performances. We confirm that the AC methods based on the Dixon and UTE sequences provided by the vendor are inferior

    In this study, the average glandular doses (DG) delivered in breast tomosynthesis examinations were estimated over a sample of 150 patients using two different methods. In method 1, the conversion factors air-kerma to DG used were those tabulated by Dance et al. and in method 2 were the ones from Feng et al. The protocol for the examination followed in the unit of this study consists in two views per breast, each view composed by a 2D acquisition and a tomosynthesis scan (3D). The resulting DG values from both methods present statistically significant differences (p=0.02) for the 2D modality and were similar for the 3D scan (p=0.22). The estimated median value of DG for the most frequent breasts (thicknesses between 50 and 60 mm) delivered in a single 3D acquisition is 1.7 mGy (36% and 17% higher than the value for the 2D mode estimated with each method) which lies far below the tolerances established by the Spanish Protocol Quality Control in Radiodiagnostic (2011). The total DG for a tomosynthesis examination (6.0 mGy) is a factor 2.4 higher than the dose delivered in a 2D examination with two views (method 1). (Author)

    Full Text Available Background and Aims: Periodontitis is one of the most common oral diseases with the various incidence rates in different populations. A number of bacteria are considered as the major etiologic agents of periodontitis. The aim of the present study was to determine the prevalence of periodontopathogen bacteria in patients using both PCR and culture techniques.Materials and Methods: In this study, one-hundred patients (including 62 females and 38 males with an average age of 49±11.5 years with adult periodontitis referred to periodontics department of School of Dentistry/Tehran University of Medical Sciences were investigated. The samples were taken and sent immediately to the laboratory for culture and molecular evaluation. The PCR was performed using specific primers and the statistical analysis of data was performed using SPSS statistic software and McNemar test.Results: The results demonstrated that the total detection rate in culture method was 64%. The rate of Aggregatibacter actinomycetemcomitans (Aa was 28% which was significantly higher than that of Porphyromonas gingivalis (Pg (6% and Prevotella intermedia (Pi (3%. 27% of cases showed mixed bacterial growth. 65% of patients were positive using molecular method. The rate of Aa (30% was significantly higher than that of Pg (7% and Pi (5%. The mixed PCR positive rate containing of Aa, Pg and Pi was (23%.Conclusion: In this study, it was found that most of the bacteria isolated using culture and molecular methods were Aa, Pg and Pi, respectively. Although the detection frequencies of both techniques were similar, the specificity, sensitivity and bacterial detection speed of the PCR technique is obviously higher. Therefore, the use of molecular techniques is strongly recommended. However, both techniques seem to be suitable for microbiological diagnostics.

    This study was designed to evaluate the perioperative nutritional status of patients undergoing surgery for gastrointestinal cancer using Subjective Global Assessment and surgeon behavior on nutritional support. We recruited 100 patients undergoing surgery for gastrointestinal cancer in one university and two state teaching hospitals. Subjective Global Assessment was administered to evaluate preoperative and postoperative nutritional status. Fifty-two patients in the state hospitals (Group 1) and 48 in the university hospital were assessed. Anthropometric and biochemical measurements were performed. Changes in preoperative Subjective Global Assessment scores and scores at the time of discharge and types of nutritional support were compared. Subjective Global Assessment-B was regarded as moderate and Subjective Global Assessment-C as heavy malnutrition. Ten patients had Subjective Global Assessment-B and 29 had Subjective Global Assessment-C malnutrition in Group 1 and nine had Subjective Global Assessment-B and 31 had Subjective Global Assessment-C malnutrition in Group 2 during preoperative assessment. Respective numbers in postoperative assessment were 12 for Subjective Global Assessment-B and 30 for Subjective Global Assessment-C in Group 1 and 14 for Subjective Global Assessment-B and 26 for Subjective Global Assessment-C in Group 2. There was no difference between two groups. Nutritional methods according to Subjective Global Assessment evaluation in pre- and postoperative periods were not different between the groups. This study demonstrated that the malnutrition rate is high among patients scheduled for gastrointestinal cancer surgery and the number of surgeons were inadequate to provide perioperative nutritional support. Both university and state hospitals had similar shortcomings. Subjective Global Assessment is an easy and reliable test and if utilized will be helpful to detect patients requiring nutritional support.

  3. Resting energy expenditure in critically ill patients: Evaluation methods and clinical applications

    Directory of Open Access Journals (Sweden)

    Ana Cláudia Soncini Sanches

    Full Text Available Summary Patients on intensive care present systemic, metabolic, and hormonal alterations that may adversely affect their nutritional condition and lead to fast and important depletion of lean mass and malnutrition. Several factors and medical conditions can influence the energy expenditure (EE of critically ill patients, such as age, gender, surgery, serious infections, medications, ventilation modality, and organ dysfunction. Clinical conditions that can present with EE change include acute kidney injury, a complex disorder commonly seen in critically ill patients with manifestations that can range from minimum elevations in serum creatinine to renal failure requiring dialysis. The nutritional needs of this population are therefore complex, and determining the resting energy expenditure is essential to adjust the nutritional supply and to plan a proper diet, ensuring that energy requirements are met and avoiding complications associated with overfeeding and underfeeding. Several evaluation methods of EE in this population have been described, but all of them have limitations. Such methods include direct calorimetry, doubly labeled water, indirect calorimetry (IC, various predictive equations, and, more recently, the rule of thumb (kcal/kg of body weight. Currently, IC is considered the gold standard.

    An accurate means of determining and correcting for daily patient setup errors is important to the cancer outcome in radiotherapy. While many tools have been developed to detect setup errors, difficulty may arise in accurately adjusting the patient to account for the rotational error components. A novel, automated method to correct for rotational patient setup errors in helical tomotherapy is proposed for a treatment couch that is restricted to motion along translational axes. In tomotherapy, only a narrow superior/inferior section of the target receives a dose at any instant, thus rotations in the sagittal and coronal planes may be approximately corrected for by very slow continuous couch motion in a direction perpendicular to the scanning direction. Results from proof-of-principle tests indicate that the method improves the accuracy of treatment delivery, especially for long and narrow targets. Rotational corrections about an axis perpendicular to the transverse plane continue to be implemented easily in tomotherapy by adjustment of the initial gantry angle

    Patients having psychiatric diagnoses often experience high level of distress. Religiousness is often used by them as part of their coping mechanism and problem-solving strategies. To determine the level of religious commitment and coping methods in psychiatric patients and its relationship with distress level. Religious commitment and coping patterns were measured with the Duke University Religious Index (DUREL) and Brief RCOPE, respectively. Psychopathology was assessed using the Brief Psychiatric Rating Scale (BPRS) and distress level was assessed with the Depressive, Anxiety and Stress Scale (DASS). Social support and experiences of recent threatening events were measured with the Multidimensional Scale of Perceived Social Support (MSPSS) and Life Threatening Events (LTE). A total of 228 patients were included in this study with a mean age of 40.2 years. The majority were male, Malay, Muslim, single and with psychotic disorder. The subjects had a high level of religious commitment and had used more positive coping methods. Negative religious coping, psychiatric symptoms and diagnosis of anxiety disorder or major depression were significantly associated with high distress level. Higher religious commitment was significantly associated with lower distress (p depression were associated with higher distress.

    Purpose: To report the 5-year prostate-specific antigen (PSA) relapse-free survival outcome and incidence of long-term morbidity for patients with localized prostate cancer treated with CT-planned permanent I-125 prostate implantation using a transperineal technique (TPI). Methods and Materials: Between 1989-1996, 248 patients with clinically localized prostate cancer were treated with TPI. The median age was 65 years (range: 45-80 years). The clinical stage was T1c in 143 patients (58%), Stage T2a in 102 (41%), and T2b in 3 (1%). Thirty patients (12%) had Gleason scores 10 ng/mL and Gleason score >6) were classified as having intermediate and unfavorable risk disease, respectively. PSA relapse was defined according to the American Society of Therapeutic Radiation Oncology Consensus Statement, and toxicity was scored according to the Radiation Therapy Oncology Group morbidity scoring scale. The median follow-up was 48 months (range: 12-126 months). Results: Thirty-eight patients (15%) developed a PSA relapse, and the overall 5-year PSA relapse-free survival (PRFS) rate was 71%. The 5-year PRFS rates for favorable-risk (n = 146), intermediate-risk (n = 85), and unfavorable-risk (n = 17) patients were 88%, 77%, and 38%, respectively (p 10 ng/mL and Gleason score >6 as independent predictors for biochemical relapse after TPI. The 5-year actuarial likelihood of late Grade 2 urinary toxicity was 41%. The 5-year likelihood of urethral stricture development was 10%, and the median time to stricture development was 18 months. One patient (0.4%) in the early phase of this clinical experience developed a Grade 4 urethral complication. The actuarial incidence of late Grade 2 rectal bleeding was 9%. One patient (0.4%) developed a Grade 4 rectal complication. Conclusions: Especially for favorable risk disease, the 5-year biochemical outcome with this approach was excellent and appears to be comparable to other therapeutic interventions. Grade 2 urinary symptoms were common in

    A new method is described for quantitative measurement of the uptake of sup(99m)Tc-methylene diphosphonate (MDP) by the sacro-iliac joints. The method uses 'regions of interest' providing advantages over the previously described 'slice' method; the two methods are compared in normal subjects, patients with known sacro-iliitis and patients with low back pain. Sacro-iliac activity, as calculated by the sacro-iliac index (SII) in normal patients, was shown to decrease with age in females but not in males. The SII was compared with radiographs of the sacro-iliac joints in the patients with known sacro-iliac joint disease and in those with low back pain. The method is useful for the exclusion of sacro-iliitis as a specific cause of back pain. (author)

    2011-01-01

    The comparatively high dose and increasing frequency of computed tomography (CT) examinations have spurred the development of techniques for reducing radiation dose to imaging patients. Among these is the application of tube current modulation (TCM), which can be applied either longitudinally along the body or rotationally along the body, or both. Existing computational models for calculating dose from CT examinations do not include TCM techniques. Dose calculations using Monte Carlo methods have been previously prepared for constant-current rotational exposures at various positions along the body and for the principle exposure projections for several sets of computational phantoms, including adult male and female and pregnant patients. Dose calculations from CT scans with TCM are prepared by appropriately weighting the existing dose data. Longitudinal TCM doses can be obtained by weighting the dose at the z-axis scan position by the relative tube current at that position. Rotational TCM doses are weighted using the relative organ doses from the principle projections as a function of the current at the rotational angle. Significant dose reductions of 15% to 25% to fetal tissues are found from simulations of longitudinal TCM schemes to pregnant patients of different gestational ages. Weighting factors for each organ in rotational TCM schemes applied to adult male and female patients have also been found. As the application of TCM techniques becomes more prevalent, the need for including TCM in CT dose estimates will necessarily increase. (author)

    Survivors of acute respiratory distress syndrome (ARDS) and other causes of critical illness often have generalized weakness, reduced exercise tolerance, and persistent nerve and muscle impairments after hospital discharge. Using an explicit protocol with a structured approach to training and quality assurance of research staff, manual muscle testing (MMT) is a highly reliable method for assessing strength, using a standardized clinical examination, for patients following ARDS, and can be completed with mechanically ventilated patients who can tolerate sitting upright in bed and are able to follow two-step commands. (7, 8) This video demonstrates a protocol for MMT, which has been taught to ≥ 43 research staff who have performed >800 assessments on >280 ARDS survivors. Modifications for the bedridden patient are included. Each muscle is tested with specific techniques for positioning, stabilization, resistance, and palpation for each score of the 6-point ordinal Medical Research Council scale. Three upper and three lower extremity muscles are graded in this protocol: shoulder abduction, elbow flexion, wrist extension, hip flexion, knee extension, and ankle dorsiflexion. These muscles were chosen based on the standard approach for evaluating patients for ICU-acquired weakness used in prior publications. (1,2).

    Western blotting with antigens purified using its specific antibody bound column has demonstrated that patients with Stiff-man syndrome (SMS) and insulin-dependent diabetic mellitus (IDDM) were both positive for anti-GAD antibody. Further, anti-GAD antibodies from various animal brains were characterized using GAD 65 and GAD 67 peptide antibody. The antibody against the anti-N-terminal peptide inhibited the enzyme activity of GAD, suggesting that the active site of GAD might exist in the N-terminal region. Development of a new detection method for anti-GAD antibody was attempted and the amount of GAD protein bound to protein G resin was determined based on the activity to release 14 CO 2 from 14 C glutamic acid. In addition, solid-phase RIA method was developed using GAD purified by the anti-peptide antibody affinity column. The positive detection rate for GAD antibody was 39% for the enzymatic method and 56% for the solid-phase RIA method. To develop a further sensitive detection method for GAD antibody, construction of recombinant GAD was attempted and two GAD65s different in molecular size were constructed using pMal-c vector. Thus obtained antibodies against anti-N-terminal peptides were separately responded to GAD65 and GAD67 isoforms in the rat, mouse and bovine brains, whereas the carboxy-terminal antibodies were reactive to both isoforms together. Therefore, it became possible to make purification of GAD65 and GAD67 by the use of the two N-terminal peptide antibodies. Further, it became possible to purify GAD as a mixture of both isoforms. However, the yield of purification using anti-affinity column was still unsatisfactory ( several percent) and the GAD preparation obtained had little activity. The positive detection by the solid-phase RIA method was 50% for SMS patients and 56% for IDDM ones, indicating that this method was superior to the previous enzyme method. The protein A method in which labeled human recombinant GAD65 was used to precipitate 125 -I

    Western blotting with antigens purified using its specific antibody bound column has demonstrated that patients with Stiff-man syndrome (SMS) and insulin-dependent diabetic mellitus (IDDM) were both positive for anti-GAD antibody. Further, anti-GAD antibodies from various animal brains were characterized using GAD 65 and GAD 67 peptide antibody. The antibody against the anti-N-terminal peptide inhibited the enzyme activity of GAD, suggesting that the active site of GAD might exist in the N-terminal region. Development of a new detection method for anti-GAD antibody was attempted and the amount of GAD protein bound to protein G resin was determined based on the activity to release {sup 14}CO{sub 2} from {sup 14}C glutamic acid. In addition, solid-phase RIA method was developed using GAD purified by the anti-peptide antibody affinity column. The positive detection rate for GAD antibody was 39% for the enzymatic method and 56% for the solid-phase RIA method. To develop a further sensitive detection method for GAD antibody, construction of recombinant GAD was attempted and two GAD65s different in molecular size were constructed using pMal-c vector. Thus obtained antibodies against anti-N-terminal peptides were separately responded to GAD65 and GAD67 isoforms in the rat, mouse and bovine brains, whereas the carboxy-terminal antibodies were reactive to both isoforms together. Therefore, it became possible to make purification of GAD65 and GAD67 by the use of the two N-terminal peptide antibodies. Further, it became possible to purify GAD as a mixture of both isoforms. However, the yield of purification using anti-affinity column was still unsatisfactory ( several percent) and the GAD preparation obtained had little activity. The positive detection by the solid-phase RIA method was 50% for SMS patients and 56% for IDDM ones, indicating that this method was superior to the previous enzyme method. The protein A method in which labeled human recombinant GAD65 was used to

    Highlights: • Abnormal {sup 18}F-FDG uptakes in the head and neck (HN) region can be carefully interpreted as being index primary, second primary cancer (SP) or benign. • {sup 18}F-FDG PET/CT identified 91.9% primary HN squamous cell carcinomas (HNSCC). • The specificity and negative predictive value of {sup 18}F-FDG PET/CT for identification of SP were as high as 98.7% and 99.3%, respectively. • Proper detection of primary tumors and SP in the HN region may promote appropriate therapeutic planning of HNSCC patients. - Abstract: Purpose: Fluorine 18-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography (PET)/computed tomography (CT) is used to identify index or second primary cancer (SP) of the head and neck (HN) through changes in {sup 18}F-FDG uptake. However, both physiologic and abnormal lesions increase {sup 18}F-FDG uptake. Therefore, we evaluated {sup 18}F-FDG uptake in the HN region to determine clinical values of abnormal tracer uptake. Methods: A prospective study approved by the institutional review board was conducted in 314 patients with newly diagnosed HN squamous cell carcinoma (HNSCC) and informed consent was obtained from all enrolled patients. The patients received initial staging workups including {sup 18}F-FDG PET/CT and biopsies. All lesions with abnormal HN {sup 18}F-FDG uptake were recorded and most of those were confirmed by biopsies. Diagnostic values for abnormal {sup 18}F-FDG uptake were calculated. Results: Abnormal {sup 18}F-FDG uptake was identified in primary tumors from 285 (91.9%) patients. False-negative results were obtained for 22.3% (23/103) T1 tumors and 2.2% (2/93) T2 tumors (P < 0.001).

    Full Text Available The electrophysiological (EF methods are objective methods for studying the visual analyzer function. These include electroretinography (ERG, electrooculography (EOG and visual evoked potentials (VEPs. ERG and EOG are used for diagnosis and monitoring of a number of diseases of the retina. VEPs depend on the functional integrity of the entire optical path from the retina through the optic nerve, optic tract, the optical radiation to the visual cortex. The electrophysiological methods are widely used in studying the function of the visual analyzer in the ophthalmic and neurological practice, for objectively measuring the visual acuity and the visual field in non-cooperative patients, small children and in simulation. Diabetes mellitus (DM is a group of metabolic diseases characterized by hyperglycemia. One of the late complications of DM is diabetic retinopathy (DR. It is one of the most serious complications of diabetes, often leading to blindness. Nowadays, DR includes retinal neurodegeneration and microvascular complications. By EF studies can evaluate the function of the retina in diabetic patients in an objective manner using ERG, that reflects the EF activity of the neurons in the retina and VEPs, which indicate the electrical conductivity across the optic tract to the visual cortex.

    The purpose of the study was to determine the stressors and coping methods of chronic haemodialysis patients in Hong Kong. Relationships among treatment-related stressors, coping methods and length of time on haemodialysis were explored. Fifty subjects completed the Haemodialysis Stressor Scale (HSS) and Jalowiec Coping Scale (JCS). Results revealed that limitation of fluid was the most frequently identified stressor, followed by limitation of food, itching, fatigue and cost. The most common coping methods are 'accepted the situation because very little could be done', followed by 'told oneself not to worry because everything would work out fine' and 'told oneself that the problem was really not that important.' It was found that the traditional philosophies of the Chinese--Confucianism, Buddhism, and Taoism--share an approach to the understanding and management of life stressors as different from that adopted by Western philosophies. The findings of this study can further facilitate nurse practitioners in providing support, information, and alternative solutions when assisting patients in coping with long-term haemodialysis.

    Full Text Available According to worldwide statistics breast cancer is the most common cancer in women. Despite the success in current methods of treatment post-operative period in major of patients is characterized by post-mastectomy syndrome which leads to impairment in daily activities, difficulties in social adaptation and consequently to dicrease of the quality of life. The specific causes, risk factors, characteristics of clinical and pathogenetic manifestations of post-mastectomy syndrome are described in detail in this review. Different approaches to post-mastectomy syndrome classification, its clinical and instrumental diagnosis are defined. Based on more than 40 publications of Russian and foreign authors, the issue of selection of appropriate treatment tactics for the syndrome is investigated and discussed in detail. A considerable part of the review is focused on the use of physical methods of treating the post-mastectomy syndrome. It is observed that an increasing number of specialists gives preference to methods of conservative treatment special of which are medical gymnastics, complex decongestive therapy and compression therapy. On the other hand, the absence of the unified treatment algorithms is challenging for clinicians. Therefore, its development with the focus on patient-specific approach is a crucial task for modern rehabilitology in breast cancer surgery.

  2. A rapid method of detecting motor blocks in patients with Parkinson's disease during volitional hand movements

    Full Text Available INTRODUCTION An algorithm to study hand movements in patients with Parkinson's disease (PD who experience temporary, involuntary inability to move a hand have been developed. In literature, this rather enigmatic phenomenon has been described in gait, speech, handwriting and tapping, and noted as motor blocks (MB or freezing episodes. Freezing refers to transient periods in which the voluntary motor activity being attempted by an individual is paused. It is a sudden, unplanned state of immobility that appears to arise from deficits in initiating or simultaneously and sequentially executing movements, in correcting inappropriate movements or in planning movements. The clinical evaluation of motor blocks is difficult because of a variability both within and between individuals and relationship of blocks to time of drug ingestion. In literature the terms freezing, motor block or motor freezing are used in parallel. AIM In clinical settings classical manifestations of Parkinson's Disease (akinesia bradykinesia, rigidity, tremor, axial motor performance and postural instability are typically evaluated. Recently, in literature, new computerized methods are suggested for their objective assessment. We propose monitoring of motor blocks during hand movements to be integrated. For this purpose we have developed a simple method that comprises PC computer, digitizing board and custom made software. Movement analysis is "off line", and the result is the data that describe the number, duration and onset of motor blocks. METHOD Hand trajectories are assessed during simple volitional self paced point-to-point planar hand movement by cordless magnetic mouse on a digitizing board (Drawing board III, 305 x 457 mm, GTCO Cal Comp Inc, Fig. 1.

    Cardiac interventional radiology has lower risks than surgical procedures. This is despite the fact that radiation doses from cardiac intervention procedures are the highest of any commonly performed general X-ray examination. Maximum radiation skin doses (MSDs) should be determined to avoid radiation-associated skin injuries in patients undergoing cardiac intervention procedures. However, real-time evaluation of MSD is unavailable for many cardiac intervention procedures. This review describes methods of determining MSD during cardiac intervention procedures. Currently, in most cardiac intervention procedures, real-time measuring of MSD is not feasible. Thus, we recommend that physicians record the patient's total entrance skin dose, such as the dose at the interventional reference point when it can be monitored, in order to estimate MSD in intervention procedures

    A method of whole-body radiometry was used to study iodine metabolism in 47 patients with lepromatous leprosy. Disorders were found in 1/3 of the cases. The level of organic iodine in the body was the most informative of all iodine metabolism indices. In the active stage of leprosy it was twice as low, on an average, as the normal one, in the stage of incomplete and stable regression it rose not reaching, however, the values of healthy persons. The content of iodine in the thyroid of leprosy patients showed a tendency to a rise starting from the active stage, however it was only in the stages of incomplete and stable regression that it significantly exceeded the normal level. The data obtained should be considered during therapy of lepers to predict and control an unfavorable complication like specific polyneuritis

  9. Oral rinse as a potential method to culture Candida isolate from AIDS patients

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Background: Candida isolate is easily sampled from oral cavity by swabbing directly on the candidiasis lesion, to be smeared onto slides for direct examination or cultured in a growth medium. This method is by far the gold standard for defining candidiasis diagnosis. However it is difficult to apply on sensitive patients and almost impossible on patients showing no clinical appearance of oral candidiasis. AIDS patients are very prone to candida infection and have a tendency of repetitive infection involving mixed species. As many candida species show different susceptibility to anti-fungal agents, it is necessary to identify the species causing the infection in the management of oral candidiasis. Oral rinse is a suggested method to obtain candida isolate to be cultured for further analysis such as species identification. This method is simple and less risky on infection transmission as less tools are required in the procedure. Purpose: This study aimed to assess the application of oral rinse as an alternative method to culture Candida isolate from AIDS patients. Methods: A cross-sectional observative study was conducted in HIV/AIDS in-Patient Facility of Intermediate Care Unit for Infection Disease, Dr. Soetomo Hospital Surabaya. Fourteen stadium 4 AIDS patients matching criteria were swabbed on 1/3-posterior of the tongue, and then given 10 ml phosphate buffer saline to rinse vigorously for 15 seconds. Both specimens were cultured on Sabouraud’s dextrose agar and colony growth was observed. Results: Candida colonies were able to grow from all 14 isolates (100% by both methods. Qualitatively, cultures from oral rinse specimens were more populated than cultures from swab specimens. Conclusion: Oral rinse is an applicable technique to obtain Candida species isolate. This technique is safe, easy, non-invasive, and needs less tools therefore less risky for HIV transmission.Latar belakang: Isolat Candida mudah diambil dengan cara mengusap lesi

    Patient experience is increasingly used as an indicator of high quality care in addition to more traditional clinical end-points. Surveys are generally accepted as appropriate methodology to capture patient experience. No validated patient experience surveys exist specifically for adolescents and young adults (AYA) aged 13-24 years at diagnosis with cancer. This paper describes early work undertaken to develop and validate a descriptive patient experience survey for AYA with cancer that encompasses both their cancer experience and age-related issues. We aimed to develop, with young people, an experience survey meaningful and relevant to AYA to be used in a longitudinal cohort study (BRIGHTLIGHT), ensuring high levels of acceptability to maximise study retention. A three-stage approach was employed: Stage 1 involved developing a conceptual framework, conducting literature/Internet searches and establishing content validity of the survey; Stage 2 confirmed the acceptability of methods of administration and consisted of four focus groups involving 11 young people (14-25 years), three parents and two siblings; and Stage 3 established survey comprehension through telephone-administered cognitive interviews with a convenience sample of 23 young people aged 14-24 years. Stage 1: Two-hundred and thirty eight questions were developed from qualitative reports of young people's cancer and treatment-related experience. Stage 2: The focus groups identified three core themes: (i) issues directly affecting young people, e.g. impact of treatment-related fatigue on ability to complete survey; (ii) issues relevant to the actual survey, e.g. ability to answer questions anonymously; (iii) administration issues, e.g. confusing format in some supporting documents. Stage 3: Cognitive interviews indicated high levels of comprehension requiring minor survey amendments. Collaborating with young people with cancer has enabled a survey of to be developed that is both meaningful to young

    Statement of Problem: Fixed orthodontic appliances in the oral cavity make tooth cleaning procedures more complicated. Objectives: This study aimed to compare the efficacy of computerized oral hygiene instruction with verbal technique among fixed orthodontic patients referred to the evening clinic of Orthodontics of Shiraz Dental School. Materials and Methods: A single-blind study was performed in Orthodontic Department of Shiraz, Islamic Republic of Iran, from January to May 2015 following the demonstrated exclusion and inclusion criteria. The sample size was considered 60 patients with 30 subjects in each group. Bleeding on probing and plaque indices and dental knowledge were assessed in the subjects to determine pre-intervention status. A questionnaire was designed for dental knowledge evaluation. The patients were randomly assigned into the computerized and verbal groups. Three weeks after the oral hygiene instruction, indices of bleeding on probing and plaque index and the dental knowledge were evaluated to investigate post-intervention outcome. The two groups were compared by chi-square and student t tests. The pre- and post-intervention scores in each group were compared using paired t-test. Results: In the computerized group, the mean score for plaque index and bleeding on probing index was significantly decreased while dental health knowledge was significantly increased after oral hygiene instruction, in contrast to the verbal group. Conclusions: Within the limitations of the current study, computerized oral hygiene instruction is proposed to be more effective in providing optimal oral health status compared to the conventional method in fixed orthodontic patients.

    Patient safety research has tended to focus on hospital settings, although most clinical encounters occur in primary care, and to emphasize practitioner errors, rather than patients' own understandings of safety. To explore patients' understandings of safety in primary care. Qualitative interviews were conducted with patients recruited from general practices in northwest England. Participants were asked basic socio-demographic information; thereafter, topics were largely introduced by interviewees themselves. Transcripts were coded and analysed using NVivo10 (qualitative data software), following a process of constant comparison. Thirty-eight people (14 men, 24 women) from 19 general practices in rural, small town and city locations were interviewed. Many of their concerns (about access, length of consultation, relationship continuity) have been discussed in terms of quality, but, in the interviews, were raised as matters of safety. Three broad themes were identified: (i) trust and psycho-social aspects of professional-patient relationships; (ii) choice, continuity, access, and the temporal underpinnings of safety; and (iii) organizational and systems-level tensions constraining safety. Conceptualizations of safety included common reliance on a bureaucratic framework of accreditation, accountability, procedural rules and regulation, but were also individual and context-dependent. For patients, safety is not just a property of systems, but personal and contingent and is realized in the interaction between doctor and patient. However, it is the systems approach that has dominated safety thinking, and patients' individualistic and relational conceptualizations are poorly accommodated within current service organization. © 2015 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    In secondary analysis of electronic health records, a crucial task consists in correctly identifying the patient cohort under investigation. In many cases, the most valuable and relevant information for an accurate classification of medical conditions exist only in clinical narratives. Therefore, it is necessary to use natural language processing (NLP) techniques to extract and evaluate these narratives. The most commonly used approach to this problem relies on extracting a number of clinician-defined medical concepts from text and using machine learning techniques to identify whether a particular patient has a certain condition. However, recent advances in deep learning and NLP enable models to learn a rich representation of (medical) language. Convolutional neural networks (CNN) for text classification can augment the existing techniques by leveraging the representation of language to learn which phrases in a text are relevant for a given medical condition. In this work, we compare concept extraction based methods with CNNs and other commonly used models in NLP in ten phenotyping tasks using 1,610 discharge summaries from the MIMIC-III database. We show that CNNs outperform concept extraction based methods in almost all of the tasks, with an improvement in F1-score of up to 26 and up to 7 percentage points in area under the ROC curve (AUC). We additionally assess the interpretability of both approaches by presenting and evaluating methods that calculate and extract the most salient phrases for a prediction. The results indicate that CNNs are a valid alternative to existing approaches in patient phenotyping and cohort identification, and should be further investigated. Moreover, the deep learning approach presented in this paper can be used to assist clinicians during chart review or support the extraction of billing codes from text by identifying and highlighting relevant phrases for various medical conditions.

The data regarding demography, bladder type, method of bladder management, and urological complications, were recorded. Bladder management methods included indwelling catheterization in 224 cases, clean intermittent catheterization (CIC in 180 cases, condom drainage in 45 cases, suprapubic cystostomy in 24 cases, reflex voiding in 32 cases, and normal voiding in 40 cases. We assessed the incidence of UTI and bacteriuria as the number of episodes per hundred person-days, and other urological complications as percentages. Results: The overall incidence of bacteriuria was 1.70 / hundred person-days. The overall incidenceof urinary tract infection was 0.64 / hundered person-days. The incidence of UTI per 100 person-days was 2.68 for indwelling catheterization, 0.34 for CIC, 0.34 for condom drainage, 0.56 for suprapubic cystostomy, 0.34 for reflex voiding, and 0.32 for normal voiding. Other urological complications recorded were urethral stricture (n=66, 12.1%, urethritis (n=78, 14.3%, periurethral abscess (n=45, 8.2%, epididymorchitis (n=44, 8.07%, urethral false passage (n=22, 4.03%, urethral fistula (n=11, 2%, lithiasis (n=23, 4.2%, hematuria (n=44, 8.07%, stress incontinence (n=60, 11%, and pyelonephritis (n=6, 1.1%. Clean intermittent catheterization was associated with lower incidence of urological complications, in comparison to indwelling catheterization. Conclusions

    Healthcare decisions, particularly those involving weighing benefits and harms that may significantly affect quality and/or length of life, should reflect patients' preferences. To support patients in making choices, patient decision aids and values clarification methods (VCM) in particular have been developed. VCM intend to help patients to determine the aspects of the choices that are important to their selection of a preferred option. Several types of VCM exist. However, they are often des...

    The study compares subjective experiences of patients, wearing complete dentures. Two different methods of determining a centric relation were performed: the traditional method using wax occlusal rims and the Gerber method, based on gothic arch tracings. The success rate of establishing a centric relation in both methods was evaluated (rentgenodiagnostics). The influence of the method used to obtain the centric relation on patients' stomatognathic system (condyle centralization, pain) was also evaluated. Better results were achieved in gothic arch tracing method. Before every prosthetic treatment of edentulous patients, a functional analysis of the TMJ is necessary. The lack of centric relation, in a long term adaptation patients, does not lead to TMD symptoms. This trial is registered with NCT03343015.

    Full Text Available Abstract Background Measures that reflect patients' assessment of their health are of increasing importance as outcome measures in randomised controlled trials. The methodological approach used in the pre-validation development of new instruments (item generation, item reduction and question formatting should be robust and transparent. The totality of the content of existing PRO instruments for a specific condition provides a valuable resource (pool of items that can be utilised to develop new instruments. Such 'top down' approaches are common, but the explicit pre-validation methods are often poorly reported. This paper presents a systematic and generalisable 5-step pre-validation PRO instrument methodology. Methods The method is illustrated using the example of the Aberdeen Glaucoma Questionnaire (AGQ. The five steps are: 1 Generation of a pool of items; 2 Item de-duplication (three phases; 3 Item reduction (two phases; 4 Assessment of the remaining items' content coverage against a pre-existing theoretical framework appropriate to the objectives of the instrument and the target population (e.g. ICF; and 5 qualitative exploration of the target populations' views of the new instrument and the items it contains. Results The AGQ 'item pool' contained 725 items. Three de-duplication phases resulted in reduction of 91, 225 and 48 items respectively. The item reduction phases discarded 70 items and 208 items respectively. The draft AGQ contained 83 items with good content coverage. The qualitative exploration ('think aloud' study resulted in removal of a further 15 items and refinement to the wording of others. The resultant draft AGQ contained 68 items. Conclusions This study presents a novel methodology for developing a PRO instrument, based on three sources: literature reporting what is important to patient; theoretically coherent framework; and patients' experience of completing the instrument. By systematically accounting for all items dropped

    We examined the relationship between CT visual score and pulmonary function studies in patients with pulmonary emphysema. Lung volume was measured using helium dilution method and body plethysmographic method. Although airflow obstruction and overinflation measured by helium dilution method did not correlate with CT visual score, CO diffusing capacity per alveolar volume (DL CO /V A ) showed significant negative correlation with CT visual score (r=-0.49, p CO /V A reflect pathologic change in pulmonary emphysema. Further, both helium dilution method and body plethysmographic method are required to evaluate lung volume of pulmonary emphysema because of its ventilatory unevenness. (author)

    Serum/plasma albumin is an important and widely used laboratory marker and it is important that we measure albumin correctly without bias. We had indications that the immunoturbidimetric method on Cobas c 501 and the bromocresol purple (BCP) method on Architect 16000 differed, so we decided to study these methods more closely. A total of 1,951 patient requests with albumin measured with both the Architect BCP and Cobas immunoturbidimetric methods were extracted from the laboratory system. A comparison with fresh plasma samples was also performed that included immunoturbidimetric and BCP methods on Cobas c 501 and analysis of the international protein calibrator ERM-DA470k/IFCC. The median difference between the Abbott BCP and Roche immunoturbidimetric methods was 3.3 g/l and the Roche method overestimated ERM-DA470k/IFCC by 2.2 g/l. The Roche immunoturbidimetric method gave higher values than the Roche BCP method: y = 1.111x - 0.739, R² = 0.971. The Roche immunoturbidimetric albumin method gives clearly higher values than the Abbott and Roche BCP methods when analyzing fresh patient samples. The differences between the two methods were similar at normal and low albumin levels. © 2016 Wiley Periodicals, Inc.

    Background: Colonic transit study provides valuable information before surgical treatment is considered for patient with constipation. The radiopaque markers method is the most common way for evaluating colon transit time. The aim of this study is to compare the barium suspension with the radiopaque makers to assess the colonic mobility in patient with constipation. Methods: Colonic transit time was measured in 11 female patients with slow-transit constipation using both radiopaque markers and barium suspension method. In radiopaque markers method, the patient ingested 20 markers on the first day, and an abdominal radiograph was performed every 24 h until 80% markers were excreted. In barium suspension method, the patient swallowed up to 50 ml of 200% (w/v) barium meal. The abdominal radiographs were taken at the same time point as the former. Results: The total or segmental colonic transit time were obviously prolonged in all patients. Segmental transits time spent in the right colon, left colon and rectosigmoid for radiopaque markers and barium suspension method was, respectively, 30 {+-} 6 h and 34 {+-} 7 h; 38 {+-} 9 h and 32 {+-} 6 h; 40 {+-} 8 h and 38 {+-} 10 h. In the radiopaque markers method, total colonic transit time was 108 {+-} 14 h and it was 103 {+-} 13 h in the barium suspension method (P > 0.05). Conclusion: The barium suspension and radiopaque markers gave the similar results for colonic transit time. The barium suspension was a simple and cheap method for evaluating the colonic mobility.

    To evaluate the effects of two different kinds of airway humidification for tracheostomy patients, and to provide their relevant clinical effect and suggestions for their use. Online databases, including PubMed, EMBASE, JBI evidence-based nursing center library, the Cochrane Library, and Chinese databases (CNKI, Wanfang database, VIP, CBM) were searched systematically up to March 2015. Randomized controlled trials (RCTs) were considered eligible for inclusion if the following criteria were met: no history of respiratory tract infection; satisfactory nutritional status; tracheotomy performed; 18 years older. Two different humidification methods were used. Continuous airway humidification was used in the experiment group, while intermittent airway humidification was used in the control group. Two qualified reviewers reviewed the original articles, evaluating the quality of articles, and data were extracted independently. The enrolled RCTs were analyzed by Meta-analysis. A total of nine RCTs were included, containing 631 cases, among them 316 cases in expertment group, and 315 cases in control group. Continuous airway humidification was shown to be able to reduce the incidence of irritable cough [odds ratio (OR) = 0.20, 95% confidence interval (95%CI) = 0.12-0.34, P humidification for tracheostomy patients. Because the number of including articles was relative small, and the quality of some articles was poor, it is impossible to draw a reliable conclusion that continuous airway humidification could lower the incidence of complications for patients undergone tracheostomy.

    An ever growing for application of electronic health records (EHRs) has improved healthcare providers' communications, access to data for secondary use and promoted the quality of services. Patient's privacy has been changed to a great issue today since there are large loads of critical information in EHRs. Therefore, many privacy preservation techniques have been proposed and anonymization is a common one. This study aimed to investigate the effectiveness of anonymization in preserving patients' privacy. The articles published in the 2005-2016 were included. Pubmed, Cochrane, IEEE and ScienceDirect were searched with a variety of related keywords. Finally, 18 articles were included. In the present study, the relevant anonymization issues were investigated in four categories: secondary use of anonymized data, re-identification risk, anonymization effect on information extraction and inadequacy of current methods for different document types. The results revealed that though anonymization cannot reduce the risk of re-identification to zero, if implemented correctly, can manage to help preserve patient's privacy.

    2015-12-01

    Full Text Available Introduction: Feedback on patient satisfaction (PS as a means to monitor and improve performance in patient communication is lacking in residency training. A physician’s promotion, compensation and job satisfaction may be impacted by his individual PS scores, once he is in practice. Many communication and satisfaction surveys exist but none focus on the emergency department setting for educational purposes. The goal of this project was to create an emergency medicine-based educational PS survey with strong evidence for content validity. Methods: We used the Delphi Method (DM to obtain expert opinion via an iterative process of surveying. Questions were mined from four PS surveys as well as from group suggestion. The DM analysis determined the structure, content and appropriate use of the tool. The group used four-point Likert-type scales and Lynn’s criteria for content validity to determine relevant questions from the stated goals. Results: Twelve recruited experts participated in a series of seven surveys to achieve consensus. A 10-question, single-page survey with an additional page of qualitative questions and demographic questions was selected. Thirty one questions were judged to be relevant from an original 48-question list. Of these, the final 10 questions were chosen. Response rates for individual survey items was 99.5%. Conclusion: The DM produced a consensus survey with content validity evidence. Future work will be needed to obtain evidence for response process, internal structure and construct validity.

    While several tools are necessary to repair a car, the engineer knows exactly which instrument he has to utilize at different parts of the broken machine. Likewise, depending on the information we are interested in, we have to choose different tools to investigate and consecutively understand the multiple aspects that are involved in pharmacokinetics of antimicrobial agents in critically ill patients. Some techniques, like blood sampling, microdialysis or positrons emission tomography (PET) will allow for obtaining continues concentration time profiles while others like bronchoalveolar lavage (BAL), biopsy or surgical tissue samples can only be used a limited number of times per subject. PET and methods based on tissue homogenization will deliver an average of the actual concentrations in intra - and extracellular compartments while investigations in isolated blood cells or microdialysis allow for more distinguished allocation of a concentration to a defined compartment. The present review aims at discussing the advantages and disadvantages of the various methods used for assessing pharmacokinetics in critically ill patients with regard to specific aspects of pharmacokinetic research and further reviews data of selected antibiotics as examples for applications of the individual techniques.

    An optimal technique was sought for lymphocyte recovery from normal and chronic diseased individuals. Lymphocytes were separated by four techniques: Plasmagel, Ficoll--Hypaque, a commercial semiautomatic method, and simple centrifugation using blood drawn from ten normal individuals, ten cancer patients, and ten tuberculosis patients. The lymphocyte mixture obtained after using each method was analyzed for percent recovery, amount if contamination by erythrocytes and neutrophils, and percent viability. The results show that the semiautomatic method yielded the best percent recovery of lymphocytes for normal individuals, while the simple centrifugation method contributed the highest percent recovery for cancer and tuberculosis patients. The Ficoll-Hypaque method gave the lowest erythrocyte contamination for all three types of individuals tested, while the Plasmagel method gave the lowest neutrophil contamination for all three types of individuals. The simple centrifugation method yielded all viable lymphocytes and thus gave the highest percent viability.

    Objectives: Perfusion abnormalities are frequently seen in Single Photon Emission Computed Tomography (SPECT) when a left bundle branch block is present. A few studies have shown decreased coronary flow reserve in the left anterior descending territory, regardless of the presence of coronary artery disease. Objective: we sought to investigate rubidium-82 ({sup 82}Rb) positron emission tomography imaging in the assessment of myocardial blood flow and coronary flow reserve in patients with left bundle branch block. Methods: thirty-eight patients with left bundle branch block (GI), median age 63.5 years, 22 (58%) female, 12 with coronary artery disease (≥70%; GI-A) and 26 with no evidence of significant coronary artery disease (GI-B), underwent rest-dipyridamole stress {sup 82}Rb-positron emission tomography with absolute quantitative flow measurements using Cedars-Sinai software (mL/min/g). The relative myocardial perfusion and left ventricular ejection fraction were assessed in 17 segments. These parameters were compared with those obtained from 30 patients with normal {sup 82}Rb-positron emission tomography studies and without left bundle branch block (GII). Results: stress myocardial blood flow and coronary flow reserve were significantly lower in GI than in GII (p>0.05). The comparison of coronary flow reserve between GI-A and GI-B showed that it was different from the global coronary flow reserve (p<0.05) and the stress flow was significantly lower in the anterior than in the septal wall for both groups. Perfusion abnormalities were more prevalent in GI-A (p=0.06) and the left ventricular ejection fraction was not different between GI-A and GI-B, whereas it was lower in GI than in GII (p<0.001). Conclusion: the data confirm that patients with left bundle branch block had decreased myocardial blood flow and coronary flow reserve and coronary flow reserve assessed by {sup 82}Rb-positron emission tomography imaging may be useful in identifying coronary artery

    To deliver client-centered care, physiotherapists need to identify the patients' individual treatment goals. However, practical tools for involving patients in goal setting are lacking. The purpose of this study was to improve the frequently used Patient-Specific Complaints instrument in Dutch physiotherapy, and to develop it into a feasible method to improve physiotherapy goal setting. An iterative user-centered design was conducted in co-creation with the physiotherapists and patients, in three phases. Their needs and preferences were identified by means of group meetings and questionnaires. The new method was tested in several field tests in physiotherapy practices. Four main objectives for improvement were formulated: clear instructions for the administration procedure, targeted use across the physiotherapy process, client-activating communication skills, and a client-centered attitude of the physiotherapist. A theoretical goal-setting framework and elements of shared decision making were integrated into the new-called, Patient-Specific Goal-setting method, together with a practical training course. The user-centered approach resulted in a goal-setting method that is fully integrated in the physiotherapy process. The new goal-setting method contributes to a more structured approach to goal setting and enables patient participation and goal-oriented physiotherapy. Before large-scale implementation, its feasibility in physiotherapy practice needs to be investigated. Implications for rehabilitation Involving patients and physiotherapists in the development and testing of a goal-setting method, increases the likelihood of its feasibility in practice. The integration of a goal-setting method into the physiotherapy process offers the opportunity to focus more fully on the patient's goals. Patients should be informed about the aim of every step of the goal-setting process in order to increase their awareness and involvement. Training physiotherapists to use a patient

    Background Obesity has been a growing problem among children and adolescents in the United States for a number of decades. Childhood cancer survivors (CCS) are more susceptible to the downstream health consequences of obesity such as cardiovascular disease, endocrine issues, and risk of cancer recurrence due to late effects of treatment and suboptimal dietary and physical activity habits. Objective The objective of this study was to document the development of a Web-based cookbook of healthy recipes and nutrition resources to help enable pediatric cancer patients and survivors to lead healthier lifestyles. Methods The Web-based cookbook, named “@TheTable”, was created by a committee of researchers, a registered dietitian, patients and family members, a hospital chef, and community advisors and donors. Recipes were collected from several sources including recipe contests and social media. We incorporated advice from current patients, parents, and CCS. Results Over 400 recipes, searchable by several categories and with accompanying nutritional information, are currently available on the website. In addition to healthy recipes, social media functionality and cooking videos are integrated into the website. The website also features nutrition information resources including nutrition and cooking tip sheets available on several subjects. Conclusions The “@TheTable” website is a unique resource for promoting healthy lifestyles spanning pediatric oncology prevention, treatment, and survivorship. Through evaluations of the website’s current and future use, as well as incorporation into interventions designed to promote energy balance, we will continue to adapt and build this unique resource to serve cancer patients, survivors, and the general public.

    Full Text Available Critically ill patient transfer is potentially risky and may be lead to morbidity and mortality. Physicians' skill is very important for safe transport. We want to evaluate the effect of clinical course teaching on the promotion of physicians' abilities in the transport of critically ill patients. In an interventional study, 320 interns, male and female, were taught about patient transfer in two groups include in one day clinical course as the small group system (n=160 and other group the lecture base learning (n=160. In the clinical course, each participant under observation of an anesthesiologist in the operation room and ICU was acquainted with mask ventilation, intubation and learned to work with a defibrillator, infusion pump, portable ventilator and pulse oximeter. In lecture group, the anesthesiologist explained the topics by video and dummy. At the end of education course, the interns’ abilities were evaluated based on checklist method and scored by the project colleague in all educational items. Three hundred twenty interns, 122 males, and 198 females; were enrolled, two groups. The clinical course training caused improvements in the interns’ knowledge and abilities in intubation and use of the defibrillator and portable ventilator vs.lecture group significantly (P<0.005. The males were better than females in laryngoscopy, but the progress of the females was significantly better than males (P=0.003. The rate of adverse events was reduced significantly after clinical course teaching (P=0.041 Clinical course teaching could promote interns' clinical competencies in the transport of critically ill patients.

    ABSTRACT Background: Despite patient safety being recognized as an important healthcare issue in the European Union, there has been variable implementation of patient safety initiatives in Central and Eastern Europe (CEE). Objective: To assess the status of patient safety initiatives in countries in CEE; to describe a process of engagement in Poland, which can serve as a template for the implementation of patient safety initiatives in primary care. Methods: A mixed methods design was used. We conducted a review of literature focusing on publications from CEE, an inventory of patient safety initiatives in CEE countries, interviews with key informants, international survey, review of national reporting systems, and pilot demonstrator project in Poland with implementation of patient safety toolkits assessment. Results: There was no published patient safety research from Albania, Belarus, Greece, Latvia, Lithuania, Romania, or Russia. Nine papers were found from Bulgaria, Croatia, the Czech Republic, Poland, Serbia, and Slovenia. In most of the CEE countries, patient safety had been addressed at the policy level although the focus was mainly in hospital care. There was a dearth of activity in primary care. The use of patient improvement strategies was low. Conclusion: International cooperation as exemplified in the demonstrator project can help in the development and implementation of patient safety initiatives in primary care in changing the emphasis away from a blame culture to one where greater emphasis is placed on improvement and learning.

    Background: There is a renewed interest in adrenal function during severe sepsis. Most studies have used total serum cortisol levels; however, only free serum cortisol is biologically active. The aim of this study was to determine the validity of salivary cortisol levels as a surrogate for free serum cortisol levels during septic shock. Methods: Fifty-seven patients with septic shock were studied to determine the correlation between total serum cortisol and salivary cortisol to free serum cortisol levels. Thirty-eight patients were included in the salivary to free serum cortisol correlation. Salivary cortisol level was tested by enzyme immunoassay. Serum total cortisol, free cortisol, and cortisol-binding globulin (CBG) levels were determined by liquid chromatography-mass spectrometry, equilibrium analysis, and radioimmunoassay, respectively. Results: The mean ± SD age was 56.6 ± 18.5 years. Fifty-seven percent were women. APACHE (Acute Physiology and Chronic Health Evaluation) II score median was 26, Simplified Acute Physiology Score II median was 61, and Sequential Organ Failure Assessment median was 13. The correlation between salivary and free serum cortisol levels was 0.79 (95% CI, 0.63-0.89; P cortisol and total serum cortisol levels was 0.86 (95% CI, 0.78-0.92; P cortisol level was 2.27 ± 1.64 μg/dL. The mean ± SD salivary cortisol level was 2.60 ± 2.69 μg/dL. The mean ± SD total serum cortisol level was 21.56 ± 8.71 μg/dL. The mean ± SD CBG level was 23.54 ± 8.33 mg/dL. Conclusions: Salivary cortisol level can be used as a surrogate of free serum cortisol level in patients with septic shock with very good correlation. Salivary cortisol testing is noninvasive, easy to perform, and can be conducted daily. Trial registry: ClinicalTrials.gov; No.: NCT00523198; URL: www.clinicaltrials.gov PMID:21816912

    We investigated to what extent psychiatric inpatients consult Heilpraktiker, i.e. non-academically trained providers of complementary and alternative medicine (CAM), which diagnostic and therapeutic methods Heilpraktiker employ, how patients assess Heilpraictikers' professional competence, CAM in general and issues of satisfaction for those who have had experience with Heilpraktiker. Four hundred and seventy three patients admitted to a psychiatric university department during a 9-month period filled out a questionnaire developed for this investigation. About one third of the patients had consulted a Heilpraktiker, a quarter of these for their current psychiatric illness. Women were in the majority. Patients with the highest secondary school education consulted Heilpraktiker less often. There was considerable 'customer loyalty' towards Heilpraktiker. Largely the same diagnostic and treatment methods were employed for mental illness as for somatic complaints. Except for iridology, exotic or dangerous methods played a secondary role. Patients generally revealed a very positive attitude toward Heilpraktiker and CAM, although methods were rated differently. CAM enjoyed greater appreciation among women and patients who had consulted Heilpraktiker. Patients with personal experience were, on the whole, very satisfied with the professional competence, with the atmosphere in the practice and staff concern for the patient's well-being. Degree of satisfaction correlated closely with frequency of consultation. More patients with neurotic disorders considered the cost unreasonable than others, despite comparatively frequent visits. Psychiatric patients seek out Heilpraktiker to a considerable degree. Especially those who have relevant experience rank Heilpraktiker highly, in particular due to their 'psychotherapeutic' attitude, but professional competence is also valued. Methods of CAM received mixed reviews from patients but are generally seen in a positive light. It is

    Purpose: To devise and implement a new system to measure and register the patient motion during radiotherapy treatments. Methods: The system can obtain the position of several points in the 3D-space, through their projections in the 2D-images recorded by two cameras. The algorithm needs a series of constants, that are obtained using the images of a calibrated phantom.To test the system, some adhesive labels were placed on the surface of an object. Two cameras recorded the moving object over time. An in-house developed software localized the labels in each image. In the first pair of images, the program used a first approximation given by the user. In the subsequent images, it used the last position as an approximate location. The final exact coordinates of the point were obtained in a two-step process using the contrast of the images. From the 2D-positions of the point in each frame, the 3D-trajectories of each of these marks were obtained.The system was tested with linear displacements, oscillations of a mechanical oscillator, circular trajectories of a rotating disk, and with respiratory motion of a volunteer. Results: Trajectories of several points were reproduced with sub-millimeter accuracy in the three directions of the space. The system was able to follow periodic motion with amplitudes lower than 0.5mm; and trajectories of rotating points at speeds up to 200mm/s. The software could also track accurately the respiration motion of a person. Conclusion: A new, inexpensive optical tracking system for patient motion has been demonstrated. The system detects motion with high accuracy. Installation and calibration of the system is simple and quick. Data collection is not expected to involve any discomfort for the patient, nor any delay for the treatment. The system could be also used as a method of warning for patient movements, and for gating.

    For decades film has proved to be a powerful form of communication. Whether produced as entertainment, art or documentary, films have the capacity to inform and move us. Films are a highly attractive teaching instrument and an appropriate teaching method in health education. It is a valuable tool for studying situations most transcendental to human beings such as pain, disease and death. The objectives were to determine how this helps students engage with their role as health care professionals; to determine how they view the personal experience of illness, disease, disability or death; and to determine how this may impact upon their provision of patient care. The project was underpinned by the film selection determined by considerate review, intensive scrutiny, contemplation and discourse by the research team. 7 films were selected, ranging from animation; foreign, documentary, biopic and Hollywood drama. Each film was shown discretely, in an acoustic lecture theatre projected onto a large screen to pre-registration student nurses (adult, child and mental health) across each year of study from different cohorts (n=49). A mixed qualitative method approach consisted of audio-recorded 5-minute reactions post film screening; coded questionnaires; and focus group. Findings were drawn from the impact of the films through thematic analysis of data sets and subjective text condensation categorised as: new insights looking through patient eyes; evoking emotion in student nurses; spiritual care; going to the moves to learn about the patient experience; self discovery through films; using films to link theory to practice. Deeper learning through film as a powerful medium was identified in meeting the objectives of the study. Integration of film into pre registration curriculum, pedagogy, teaching and learning is recommended. The teaching potential of film stems from the visual process linked to human emotion and experience. Its impact has the power to not only help in

    A total of 135 patients with advanced squamous-cell carcinoma of the head and neck were treated with cyclotron-generated fast neutrons. Thirty-eight had major surgery before or after irradiation. Major complications (fistula formation, carotid artery exposure or blowout requiring ligation, or major wound breakdown) occurred in 37%. The complication rates associated with surgery prior to irradiation, planned surgery following irradiation, and salvage surgery following irradiation were 0/12, 4/5, and 10/21, respectively. The complication rate for surgery following neutron irradiation alone was 73%; for surgery following mixed-beam irradiation it was 20%. The age of the patient and the interval between surgery and irradiation had no influence on the complication rate

    To examine the effects of Reiki as an adjuvant therapy to opioid therapy for postoperative pain control in pediatric patients. This was a double-blind, randomized controlled study of children undergoing dental procedures. Participants were randomly assigned to receive either Reiki therapy or the control therapy (sham Reiki) preoperatively. Postoperative pain scores, opioid requirements, and side effects were assessed. Family members were also asked about perioperative care satisfaction. Multiple linear regressions were used for analysis. Thirty-eight children participated. The blinding procedure was successful. No statistically significant difference was observed between groups on all outcome measures. Our study provides a successful example of a blinding procedure for Reiki therapy among children in the perioperative period. This study does not support the effectiveness of Reiki as an adjuvant therapy to opioid therapy for postoperative pain control in pediatric patients. Copyright © 2013 Elsevier Ltd.

    Empathy is increasingly being recognized as a crucial component for an effective doctor-patient relationship. Using a mixed method approach, we surveyed 125 patients and 361 medical practitioners (doctors and medical students) views of the doctor-patient relationship. We qualitatively assessed patients' views of what constituted a good doctor and qualitatively measured empathy using a validated scale in medical practitioners. Patients desire a doctor that is both clinically proficient 66 (55%) and caring 32 (27%). Doctors who have a personal experience of illness have a statistically higher empathy score. These doctors may be well placed to help develop and foster empathy in our profession.

    This study aims to examine Gender Difference in the level of Discrimination and Stigma experienced by people diagnosed with Major Depressive Disorder in Pakistan. It was hypothesized that Women diagnosed with Depression are likely to be experiencing more Discrimination and Internalized Stigma in comparison to Men. This is a Cross Sectional Study. Thirty eight patients diagnosed with Major Depressive Disorder recruited from different Government Sector Hospitals of Lahore; were approached after obtaining informed consent. Discrimination and Stigma were measured through Discrimination and Stigma Scale and Internalized Stigma of Mental Illness Inventory respectively. Both Men and Women experience considerably high level of associated Stigma and Discrimination due to their Mental Illness. However, Women in comparison to Men experience significantly greater level of Internalized Stigma especially in domains of Discrimination Experience and Social Withdrawal. The findings of this study highlight the fact that people with Depression can be more benefited with psychological treatment if dealing with Stigma and Discrimination is also addressed in Intervention Plans.

    The aim of this crossover study was to assess perceptions and preferences for impression techniques in young orthodontic patients receiving alginate and 2 different digital impressions. Thirty-eight subjects aged 10 to 17 years requiring impressions for orthodontic treatment were randomly allocated to 3 groups that differed in the order that an alginate impressions and 2 different intraoral scanning procedures were administered. After each procedure, the patients were asked to score their perceptions on a 5-point Likert scale for gag reflex, queasiness, difficulty to breathe, uncomfortable feeling, perception of the scanning time, state of anxiety, and use of a powder, and to select the preferred impression system. Chairside time and maximal mouth opening were also registered. More queasiness (P = 0.00) and discomfort (P = 0.02) during alginate impression taking of the maxilla were perceived compared with the scans with the CEREC Omnicam (Sirona Dental Systems, Bensheim, Germany). There were no significant differences in perceptions between the alginate impressions and the Lava C.O.S. (3M ESPE, St Paul, Minn) and between the 2 scanners. Chairside times for the alginate impressions (9.7 ± 1.8 minutes) and the CEREC Omnicam (10.7 ± 1.8 minutes) were significantly lower (P <0.001) than for the Lava C.O.S. (17.8 ± 4.0 minutes). Digital impressions were favored by 51% of the subjects, whereas 29% chose alginate impressions, and 20% had no preference. Regardless of the significant differences in the registered times among the 3 impression-taking methods, the distributions of the Likert scores of time perception and maximal mouth opening were similar in all 3 groups. Young orthodontic patients preferred the digital impression techniques over the alginate method, although alginate impressions required the shortest chairside time.

    Full Text Available The objective of this study was to assess spiritual needs of patients with fibromyalgia syndrome (FMS and to evaluate correlations with disease and health associated variables. Using a set of standardized questionnaires (i.e., Spiritual Needs Questionnaire, Fibromyalgia Impact Questionnaire, SF-36's Quality of Life, Brief Multidimensional Life Satisfaction Scale, etc., we enrolled 141 patients (95% women, mean age 58 ± 10 years. Here, needs for inner peace and giving/generativity scored the highest, while existential needs and religious needs scored lowest. Particularly inner peace needs and existential needs correlated with different domains of reduced mental health, particularly with anxiety, the intention to escape from illness, and psychosocial restrictions. Thirty-eight percent of the patients stated needs to be forgiven and nearly half to forgive someone from their past life. Therefore, the specific spiritual needs of patients with chronic diseases should be addressed in clinical care in order to identify potential therapeutic avenues to support and stabilize their psychoemotional situation.

    Full text: Introduction: The incidence of cardio - metabolic diseases increase in an increasingly early age is one of the challenges of the 21st century. This phenomenon is attributed largely of the obesity epidemic, it is particularly significant when the obesity occurs in childhood - obese children have a greater probability of developing cardiovascular disease and diabetes earlier. What you will learn: The significance of the obesity epidemic in childhood and metabolic risk increase; The compartment of adipose tissue and their role in maintaining metabolic balance and its breach; The importance of imaging methods in recent studies related to obesity and cardio - metabolic diseases in children; New imaging methods for proofing of pathological fat accumulation in other tissues and organs and their role in the study of metabolic disorders. Discussion: Various studies of pathology at obesity prove that obesity indicators are not sufficient for individualized assessment of cardio - metabolic risk. Only by imaging methods, information about the accumulated fat in metabolically more active visceral and ectopic adipose tissue depots has been obtained. The most common imaging techniques for analysis of body composition and adiposity in children - dual-energy X-ray absorptiometry (DXA), ultrasound , computed tomography ( CT) scan , magnetic resonance imaging ( MRI), magnetic resonance spectroscopy (MRS) will be presented. Conclusion: The imaging methods are widely used in the obesity and metabolic risk studies, as the trend is to be applied increasingly into practice. The results from Imaging studies affect not only to therapeutic approach, but also to the motivation of parents and patients to comply prescribed measures

    Existing research of patient-specific computational hemodynamics (PSCH) heavily relies on software for anatomical extraction of blood arteries. Data reconstruction and mesh generation have to be done using existing commercial software due to the gap between medical image processing and CFD, which increases computation burden and introduces inaccuracy during data transformation thus limits the medical applications of PSCH. We use lattice Boltzmann method (LBM) to solve the level-set equation over an Eulerian distance field and implicitly and dynamically segment the artery surfaces from radiological CT/MRI imaging data. The segments seamlessly feed to the LBM based CFD computation of PSCH thus explicit mesh construction and extra data management are avoided. The LBM is ideally suited for GPU (graphic processing unit)-based parallel computing. The parallel acceleration over GPU achieves excellent performance in PSCH computation. An application study will be presented which segments an aortic artery from a chest CT dataset and models PSCH of the segmented artery.

The treatment starts from prophylactic prescription of antibacterial antibiotics of latest generations (imipinem, cephalosporin of 3-rd generation), antifungal and antiviral remedies, immunoglobulin G, selective decontamination of intestines should be carried out. Transfusion of donor thrombocytes and erythrocytes in the quantities adequate to the degree of explicit cytopenia should be provided. Full parenteral feeding should be prescribed, desintoxication and adjustment therapy is be administered. Transplantation of HLA-identical bone marrow may be recommended only over the range from 10 to 15 Gy close to uniform irradiation. The most promising in the therapy of acute radiation disease - 3, 4 are hemopoietic growth factors. 76 refs.; 2 tabs

    Goal-directed delivery of sedative and analgesic medications is recommended as standard care in intensive care units (ICUs) because of the impact these medications have on ventilator weaning and ICU length of stay, but few of the available sedation scales have been appropriately tested for reliability and validity. To test the reliability and validity of the Richmond Agitation-Sedation Scale (RASS). Prospective cohort study. Adult medical and coronary ICUs of a university-based medical center. Thirty-eight medical ICU patients enrolled for reliability testing (46% receiving mechanical ventilation) from July 21, 1999, to September 7, 1999, and an independent cohort of 275 patients receiving mechanical ventilation were enrolled for validity testing from February 1, 2000, to May 3, 2001. Interrater reliability of the RASS, Glasgow Coma Scale (GCS), and Ramsay Scale (RS); validity of the RASS correlated with reference standard ratings, assessments of content of consciousness, GCS scores, doses of sedatives and analgesics, and bispectral electroencephalography. In 290-paired observations by nurses, results of both the RASS and RS demonstrated excellent interrater reliability (weighted kappa, 0.91 and 0.94, respectively), which were both superior to the GCS (weighted kappa, 0.64; P<.001 for both comparisons). Criterion validity was tested in 411-paired observations in the first 96 patients of the validation cohort, in whom the RASS showed significant differences between levels of consciousness (P<.001 for all) and correctly identified fluctuations within patients over time (P<.001). In addition, 5 methods were used to test the construct validity of the RASS, including correlation with an attention screening examination (r = 0.78, P<.001), GCS scores (r = 0.91, P<.001), quantity of different psychoactive medication dosages 8 hours prior to assessment (eg, lorazepam: r = - 0.31, P<.001), successful extubation (P =.07), and bispectral electroencephalography (r = 0.63, P

    Full Text Available The aim of the paper was to evaluate the surgical outcome in patients with spontaneous supratentorial intracerebral hemorrhage (ICH after surgical intervention, in respect to the initial clinical conditions, age, sex, hemispheric side and anatomic localization of ICH. Thirty-eight surgically treated patients with spontaneous supratentorial intracerebral hemorrhage were included in the study. The surgical outcome was evaluated three months after the initial admission, according to the Glasgow Outcome Scale (GOS. The surgical treatment was successful in 14 patients (37%, whereas it was unsuccessful in 24 patients (63%. We have detected a significant negative correlation between the Glasgow Coma Scale (GCS scores on admission and the GOS scores after three months, suggesting worse neurological outcome in patients with initially lower GCS scores. The surgical outcome in patients with ICH was not affected by the sex, the hemispheric side and the anatomic localization of ICH, but the age of the patients was estimated as a significant factor for their functional outcome, with younger patients being more likely to be treated successfully. The surgical outcome is affected from the initial clinical state of the patients and their age. The treatment of ICH is still an unsolved clinical problem and the development of new surgical techniques with larger efficiency in the evacuation of the hematoma is necessary, thus making a minimal damage to the normal brain tissue, as well as decreasing the possibility of postoperative bleeding.

    The purpose of this study was to evaluate plasma methionine levels by using liquid chromatography electrospray ionization-tandem mass spectroscopy (LC-ESI-MS/MS) in schizophrenic patients. A twelve-point standard graph was drawn, and the recovery rate, the intra-day and inter-day coefficients of variation (CV), the limit of detection (LOD), and the limit of quantification (LOQ) were evaluated. The y and R2 values of the standard graph equation were determined as 0.011x + 0.0179 and 0.9989, respectively, and the graph remained linear until the 200 µmol/l level. The intra-day coefficients of variation of the samples (n = 10) containing 8, 28, and 58 µmol/l methionine were determined as 2.68, 3.10, and 3.79%, respectively; while their inter-day coefficients of variation were determined as 2.98, 3.19, and 3.84%. The LOD and LOQ values were determined as 0.04 and 0.1 µmol/l, respectively, while the mean recovery rates were determined as 101.7 and 99.3%. Plasma methionine values were measured as 21.5 (19.5-24,6) µmol/l for the patient group, 17.8 (16.3-20.1) µmol/l for the control group, and the difference between the two groups was statistically significant (p = 0.03). LC-ESI-MS/MS method represents a fairly sensitive, economic, and rapid analysis that requires very little sample and is suitable for measuring methionine levels in schizophrenic patients.

    At the bedside, the reference method for creatinine clearance determination is based on the measurement of creatinine concentrations in urine and serum (mCrCl). Several models are available to calculate the creatinine clearance from the serum creatinine concentration. This observational survey aimed at testing the hypothesis that the proposed equations are unreliable to determine accurate creatinine clearance in patients admitted to intensive care unit (ICU). Creatinine clearance was determined by the use of mCrCl. Then, we compared three equations: Cockcroft-Gault (CG), Simplified Modification of Diet in Renal Disease (MDRDs), and Chronic Kidney Disease Epidemiology (CKD-EPI) in 156 consecutive patients within the first 24hours after ICU admission. We tested the hypothesis that the three equations were equivalent. The agreement between the three equations was evaluated by linear regression and Bland and Altman analysis. Bland and Altman analysis showed similar agreement between the three equations. The biases and precisions were -4.8±51, -1.3±50, and 8.2±44 for CG, MDRDs, and CKD-EPI equations, respectively (P>0.05). The precisions were similar for the three equations (P>0.05). The percentages of outliers at ±30% were 44%, 45%, and 49% for CG, MDRDs, and CKD-EPI, respectively (P>0.05). Regarding the high percentage of outliers, the use of these equations cannot be recommended in ICU patients. Copyright © 2014 Société française d’anesthésie et de réanimation (Sfar).

    Cow's milk allergy (CMA) is the most frequent food allergy in children and oral immunotherapy (OIT) is a promising approach for treatment of patients. The most challenging cases are anaphylactic with coexisting asthma and proposing safe protocols is crucial especially in high risk groups. Considering that CMA varies among patients, an individualized OIT protocol would be beneficial to achieve a safer and more efficient method of desensitization. 18 children more than 3 years of age with IgE-mediated CMA were enrolled. CMA was confirmed by positive skin prick test (SPT) and positive oral food challenge (OFC) and 60% of individuals had a convincing history of persistent asthma. SPT with milk extracts, whole fresh milk and serially diluted milk concentrations were performed.  The dilution of milk that induced 3-5 mm of wheal in each individual was selected as the starting dilution for OIT. Desensitization began by 1 drop of the defined dilution and continued increasingly. Overall, 16 out of 18 children (88.8%) achieved the daily intake of 120 mL of milk. Four out of these 16 children accomplished the protocol without any adverse allergic reactions. 12 patients experienced mild to severe reactions. Wheal and erythema in SPT (p≤0.001), and sIgE (p≤0.003) to most milk allergens were significantly decreased following desensitization. We successfully desensitized 16 of 18 children with IgE-mediated CMA by individualized desensitization protocol. Individualizing the OIT protocol would be helpful to save time and perhaps to relieve the allergic symptoms after ingesting cow's milk intake.

    There is still no reliable tool to determine the outcome of the repaired unilateral cleft lip (UCL). The aim of this study was therefore to develop an accurate, reliable tool to measure vertical lip height from photographs. The authors measured the vertical height of the cutaneous and vermilion parts of the lip in 72 anterior-posterior view photographs of 17 patients with repairs to a UCL. Points on the lip's white roll and vermillion were marked on both the cleft and the noncleft sides on each image. Two new concepts were tested. First, photographs were standardized using the horizontal (medial to lateral) eye fissure width (EFW) for calibration. Second, the authors tested the interpupillary line (IPL) and the alar base line (ABL) for their reliability as horizontal lines of reference. Measurements were taken by 2 independent researchers, at 2 different time points each. Overall 2304 data points were obtained and analyzed. Results showed that the method was very effective in measuring the height of the lip on the cleft side with the noncleft side. When using the IPL, inter- and intra-rater reliability was 0.99 to 1.0, with the ABL it varied from 0.91 to 0.99 with one exception at 0.84. The IPL was easier to define because in some subjects the overhanging nasal tip obscured the alar base and gave more consistent measurements possibly because the reconstructed alar base was sometimes indistinct. However, measurements from the IPL can only give the percentage difference between the left and right sides of the lip, whereas those from the ABL can also give exact measurements. Patient examples were given that show how the measurements correlate with clinical assessment. The authors propose this method of photogrammetry with the innovative use of the IPL as a reliable horizontal plane and use of the EFW for calibration as a useful and reliable tool to assess the outcome of UCL repair.

    Full Text Available Abstract Background Antimicrobial resistance is a public health challenge supplemented by inappropriate prescribing, especially for an upper respiratory tract infection in primary care. Patient/carer expectations have been identified as one of the main drivers for inappropriate antibiotics prescribing by primary care physicians. The aim of this study was to understand who is more likely to expect an antibiotic for an upper respiratory tract infection from their doctor and the reasons underlying it. Methods This study used a sequential mixed methods approach: a nationally representative cross sectional survey (n = 1509 and four focus groups. The outcome of interest was expectation and demand for an antibiotic from a doctor when presenting with a cold or flu. Results The study found 19.5 % of survey respondents reported that they would expect the doctor to prescribe antibiotics for a cold or flu. People younger than 65 years of age, those who never attended university and those speaking a language other than English at home were more likely to expect or demand antibiotics for a cold or flu. People who knew that ‘antibiotics don’t kill viruses’ and agreed that ‘taking an antibiotic when one is not needed means they won’t work in the future’ were less likely to expect or demand antibiotics. The main reasons for expecting antibiotics were believing that antibiotics are an effective treatment for a cold or flu and that they shortened the duration and potential deterioration of their illness. The secondary reason centered around the value or return on investment for visiting a doctor when feeling unwell. Conclusion Our study found that patients do not appear to feel they have a sufficiently strong incentive to consider the impact of their immediate use of antibiotics on antimicrobial resistance. The issue of antibiotic resistance needs to be explained and reframed as a more immediate health issue with dire consequences to ensure the

    Fabry disease is an X-linked lysosomal storage disorder caused by deficiency of α-galactosidase A, resulting in the accumulation of glycosphingolipids in various organs. Globotriaosylceramide (Gb3) and its isoforms and analogues have been identified and quantified as biomarkers of disease severity and treatment efficacy. The current study aimed to establish rapid methods for urinary Gb3 extraction and quantitation. Urine samples from 15 Fabry patients and 21 healthy control subjects were processed to extract Gb3 by mixing equal volumes of urine, methanol containing an internal standard, and chloroform followed by sonication and centrifugation. Thereafter, the lower phase was analyzed by MALDI-TOF MS and the relative peak areas of the internal standard and four major species of Gb3 determined. The results showed high reproducibility with intra- and inter-assay coefficients variation of 9.9% and 13.7%, respectively. The limit of detection was 0.15 ng/μL and the limit of quantitation was 0.30 ng/μL. Total urinary Gb3 levels in both genders of classic Fabry patients were significantly higher than in healthy controls (p < 0.0001). Gb3 levels in Fabry males were higher than in Fabry females (p = 0.08). We have established a novel assay for urinary total Gb3 that takes less than 15 min from start to finish.

Methods: A total of 81 diabetic nephropathy patients were randomly divided into on hemodialysis group (HD, n=27, hemodialysis with hemoperfusion group (HD+HP, n=27, online hemodiafiltration group (OL-HDF, n=27. Levels of adiponectin, resistin, interleukin-6 (IL-6, and tumor necrosis factor (TNF-α were tested and compared before and after treatment. Results: Indicators of HD group have no statistical significance before and after treatment. HD+HP and OL-HDF group adiponectin level increased significantly, resistin, IL-6 and TNF-α level decreased significantly before and after treatment; OL-HDF group resistin, IL-6 and TNF-α level decreased more significantly than HD+HP group after treatment. Conclusion: HD+HP and OL-HDF treatments have reliable curative effect on diabetic nephropathy patients, which can regulate adiponectin, resistin, IL-6 and TNF-α level. Effect of OL-HDF treatment eliminates resistin, IL-6 and TNF-α more markedly than HD+HP treatment.

  6. Simple and effective method to lower body core temperatures of hyperthermic patients.

    Hyperthermia is a potentially life threatening scenario that may occur in patients due to accompanying morbidities, exertion, or exposure to dry and arid environmental conditions. In particular, heat stroke may result from environmental exposure combined with a lack of thermoregulation. Key clinical findings in the diagnosis of heatstroke are (1) a history of heat stress or exposure, (2) a rectal temperature greater than 40 °C, and (3) central nervous system dysfunction (altered mental state, disorientation, stupor, seizures, or coma) (Prendergast and Erickson, 2014 [1]). In these patients, it is important to bring the body's core temperature down to acceptable levels in a short period of time to avoid tissue/organ injury or death (Yoder, 2001; Casa et al., 2007 [2,3]). A number of potential approaches, both non-invasive and invasive, may be used to lower the temperature of these individuals. Non-invasive techniques generally include: evaporative cooling, ice water immersion, whole-body ice packing, strategic ice packing, and convective cooling. Invasive approaches may include gastric lavage or peritoneal lavage (Schraga and Kates [4]). The efficacy of these methods vary and select treatment approaches may be unsuitable for specific individuals (Schraga and Kates [4]). In this work, the effectiveness of radiation cooling of individuals as a stand-alone treatment and comparisons with existing noninvasive techniques are presented. Copyright © 2017 Elsevier Inc.

  11. AN EMPIRICAL METHOD FOR MATERIALITY: WOULD CONFLICT OF INTEREST DISCLOSURES CHANGE PATIENT DECISIONS?

    2014-01-01

    The law has long been concerned with the agency problems that arise when advisors, such as attorneys or physicians, put themselves in financial relationships that create conflicts of interest. If the financial relationship is "material" to the transactions proposed by the advisor, then non-disclosure of the relationship may be pertinent to claims of malpractice, informed consent, and even fraud, as well as to professional discipline. In these sorts of cases, materiality is closely related to the question of causation, roughly turning on whether the withheld information might have changed the decision of a reasonable advisee (i.e., a patient). The injured plaintiff will predictably testify that the information would have impacted his or her choice, but that self-serving testimony may be unreliable. The fact finder is left to speculate about the counterfactual world in which the information was disclosed. This Article shows how randomized vignette-based experimentation may create a valuable form of evidence to address these questions, for both litigation and policymaking. To demonstrate this method and investigate conflicts of interest in healthcare in particular, we recruited 691 human subjects and asked them to imagine themselves as patients facing a choice about whether to undergo a cardiac stenting procedure recommended by a cardiologist. We manipulated the vignettes in a 2 x 3 between-subjects design, where we systematically varied the appropriateness of the proposed treatment, which was described in terms of patient risk without the procedure (low or high), and manipulated the type of disclosure provided by the physician (none, standard, or enhanced). We used physician ownership of the specialty hospital where the surgery would be performed as the conflict of interest, disclosed or not, and the "enhanced" disclosure included notice that such relationships have been associated with biases in prescribing behavior. We found that the mock patients were

    Patient participation and goal setting appear to be difficult in daily physiotherapy practice, and practical methods are lacking. An existing patient-specific instrument, Patient-Specific Complaints (PSC), was therefore optimized into a new Patient Specific Goal-setting method (PSG). The aims of this study were to examine the feasibility of the PSG in daily physiotherapy practice, and to explore the potential impact of the new method. We conducted a process evaluation within a non-controlled intervention study. Community-based physiotherapists were instructed on how to work with the PSG in three group training sessions. The PSG is a six-step method embedded across the physiotherapy process, in which patients are stimulated to participate in the goal-setting process by: identifying problematic activities, prioritizing them, scoring their abilities, setting goals, planning and evaluating. Quantitative and qualitative data were collected among patients and physiotherapists by recording consultations and assessing patient files, questionnaires and written reflection reports. Data were collected from 51 physiotherapists and 218 patients, and 38 recordings and 219 patient files were analysed. The PSG steps were performed as intended, but the 'setting goals' and 'planning treatment' steps were not performed in detail. The patients and physiotherapists were positive about the method, and the physiotherapists perceived increased patient participation. They became aware of the importance of engaging patients in a dialogue, instead of focusing on gathering information. The lack of integration in the electronic patient system was a major barrier for optimal use in practice. Although the self-reported actual use of the PSG, i.e. informing and involving patients, and client-centred competences had improved, this was not completely confirmed by the objectively observed behaviour. The PSG is a feasible method and tends to have impact on increasing patient participation in the goal

    Full Text Available Background and Objective: One of the major issues in hemodialysis patients is adherence to diet and fluid restriction. In order to reduce the adverse consequences of the disease and improve quality of life, educating these patients is of great importance. Therefore, the present study was conducted in order to compare the impact of two methods of education (patient-centered and family–centered on attitude toward and adherence to diet and fluid restriction in hemodialysis patients. Materials and Method: This clinical trial was performed on patients referred to the hemodialysis ward of hospitals affiliated with Tehran University of Medical Sciences, Iran, during May to October 2012. Through purposive sampling method, 60 patients were selected and randomly assigned to two groups patient-centered (n = 30 and family-centered (n = 30. Patients’ attitude toward and adherence to diet regime and fluid restriction were assessed using a researcher-made self-report questionnaire in 3 stages (before the intervention, and 2 and 4 weeks after the intervention. The reliability and validity of the questionnaire were approved. Data analysis was performed using SPSS software version 16 and independent t-test, chi-square, Fisher’s exact test, and repeated measures ANOVA. Results: Before the intervention, the findings showed no significant difference between the 2 groups in terms of adherence to diet and fluid restriction. In the second week after the intervention, mean adherence to diet in the family-centered group was significantly higher than the patient-centered group (P = 0.010. Moreover, at the end of the second (P = 0.001 and fourth weeks (P = 0.002, the attitude toward adherence to diet and fluid restriction was more positive in the family-centered group, in comparison to the patient-centered group. Conclusion: Family-centered education is more effective on patient adherence to the treatment regimen. Thus, it is recommended that family

    To evaluate the improvement of prostate cancer detection provided by transrectal ultrasound (TRUS)-guided 12 core biopsy method compared with sextant biopsy method. Between June 1997 and February 1999, 29 patients with pathologically proven prostate cancer in 124 patients who underwent TRUS-guided 12 core biopsy method were evaluated. They had abnormal findings in prostate specific antigen (PSA), digital rectal examination (DRE) or TRUS findings. The prostate was diffusely enlarged in all patients on DRE findings and in 15 cases (15/29, 52%), hard nodule was palpated. The average of PSA and prostate specific antigen density (PSAD) is 229.33 ng/ml (1-2280) and 9.14 ng/ml/cm 3 (0.048-142.5), respectively, 12 transrectal biopsy, including 2 transition zones, was performed in both lobe, 6 biopsies were located in both base, middle and apex. Then 2 biopsies were inserted between 3 biopsies in both peripheral zone and 2 biopsies were performed in both transition zone. Each specimen was pathologically examined. The results of pathology were compared with method 1 and 2, respectively. We defined the method 1 and 2 as different sextant biopsy method. The method 1 is that cores are taken from both base, middle and apex and method 2 is that cores are taken from both base, apex and transition zone. TRUS findings were analyzed by two radiologists. Of the 29 patients with prostate cancer, 3 (10%) had carcinomas only in the additional regions as compared with method. When compared with method 2,2 (7.0%) had carcinomas only in the additional regions. 2 patients were same in both cases. TRUS findings were abnormal in 21 cases in all patients whose 12 biopsy method was not helpful. 12 biopsy method was helpful in 2/8 (25%) whose TRUS findings were non-specific and 1/21 (4.8%) whose TRUS findings were abnormal. Small low echoic lesion was seen in one patients whose 12 biopsy method was helpful, but cancer was found in other area. TRUS-guided 12 core biopsy method may be superior to

    Full Text Available Rapid prototyping of microchannel gain lots of attention from researchers along with the rapid development of microfluidic technology. The conventional methods carried few disadvantages such as high cost, time consuming, required high operating pressure and temperature and involve expertise in operating the equipment. In this work, new method adapting xurography method is introduced to replace the conventional method of fabrication of microchannels. The novelty in this study is replacing the adhesion film with clear plastic film which was used to cut the design of the microchannel as the material is more suitable for fabricating more complex microchannel design. The microchannel was then mold using polymethyldisiloxane (PDMS and bonded with a clean glass to produce a close microchannel. The microchannel produced had a clean edge indicating good master mold was produced using the cutting plotter and the bonding between the PDMS and glass was good where no leakage was observed. The materials used in this method is cheap and the total time consumed is less than 5 hours where this method is suitable for rapid prototyping of microchannel.

Participants Four hospitals (one in each country in the UK) participating in the first phase of the SPI (SPI1); 18 control hospitals. Intervention The SPI1 was a compound (multi-component) organisational intervention delivered over 18 months that focused on improving the reliability of specific frontline care processes in designated clinical specialties and promoting organisational and cultural change. Results Senior staff members were knowledgeable and enthusiastic about SPI1. There was a small (0.08 points on a 5 point scale) but significant (Porganisational climate). Qualitative evidence showed only modest penetration of SPI1 at medical ward level. Although SPI1 was designed to engage staff from the bottom up, it did not usually feel like this to those working on the wards, and questions about legitimacy of some aspects of SPI1 were raised. Of the five components to identify patients at risk of deterioration—monitoring of vital signs (14 items); routine tests (three items); evidence based standards specific to certain diseases (three items); prescribing errors (multiple items from the British National Formulary); and medical history taking (11 items)—there was little net difference between control and SPI1 hospitals, except in relation to quality of monitoring of acute medical patients, which improved on average over time across all hospitals. Recording of respiratory rate increased to a greater degree in SPI1 than in control hospitals; in the second six hours after admission recording increased from 40% (93) to 69% (165) in control hospitals and from 37% (141) to 78% (296

    Traditional in-person cardiac rehabilitation has substantial benefits for cardiac patients, which are offset by poor attendance. The rapid increase in social media use in older adults provides an opportunity to reach patients who are eligible for cardiac rehabilitation but unable to attend traditional face-to-face groups. However, there is a paucity of research on cardiac patients' experiences and perspectives on using social media to support their health. The aim of this study was to describe cardiac rehabilitation patients' experiences in using social media in general and their perspective on using social media, particularly Facebook, to support their cardiac health and secondary prevention efforts. A mixed-methods study was undertaken among cardiac rehabilitation patients in both urban and rural areas. First, this study included a survey (n=284) on social media use and capability. Second, six focus group interviews were conducted with current Facebook users (n=18) to elucidate Facebook experience and perspectives. Social media use was low (28.0%, 79/282) but more common in participants who were under 70 years of age, employed, and had completed high school. Social media users accessed Web-based information on general health issues (65%, 51/79), medications (56%, 44/79), and heart health (43%, 34/79). Participants were motivated to invest time in using Facebook for "keeping in touch" with family and friends and to be informed by expert cardiac health professionals and fellow cardiac participants if given the opportunity. It appeared that participants who had a higher level of Facebook capability (understanding of features and the consequences of their use and efficiency in use) spent more time on Facebook and reported higher levels of "liking," commenting, or sharing posts. Furthermore, higher Facebook capability appeared to increase a participants' willingness to participate in a cardiac Facebook support group. More capable users were more receptive to the use

    The Clauss fibrinogen method and thrombin clotting time (TCT) are still routinely used in patients with cirrhosis to define fibrinogen concentration and clotting potential. The thromboelastometric functional fibrinogen FIBTEM assay evaluates the strength of fibrin-based clots in whole blood, providing information on both quantitative deficit and fibrin polymerization disorders. To compare these three methods of assessing fibrinogen in patients with cirrhosis of different aetiologies, characterized by impairment in fibrinogen concentration as well as functional aberrance. Sixty patients with alcoholic and 24 patients with cholestatic cirrhosis were included (Child-Pugh score (CPs)A, n=24; B, n=32; C, n=28). All parameters were compared with those from a control group. Maximum clot firmness (MCF) in the FIBTEM test was assessed in regard to its relevance in detection of qualitative fibrinogen disorders in comparison with results obtained by standard measurement methods, i.e. the Clauss fibrinogen method and TCT. With increased cirrhosis severity, fibrinogen and FIBTEM-MCF levels significantly declined (p=0.002), while TCT was significantly prolonged (p=0.002). In all CPs groups, fibrinogen strongly correlated with FIBTEM-MCF (r=0.77, r=0.72, r=0.74; pmeasurement in cirrhotic patients, especially in evaluating fibrin polymerization disorders in these patients. Further studies are needed to evaluate the usefulness of this assay in predicting bleeding complications in cirrhotic patients as well as monitoring replacement treatment.

    Purpose: To prospectively investigate the efficacy and toxicity of accelerated hypofractionated thoracic radiation therapy (HypoTRT) combined with concurrent chemotherapy in the treatment of limited-stage small-cell lung cancer (LS-SCLC), with the hypothesis that both high radiation dose and short radiation time are important in this setting. Methods and Materials: Patients with previously untreated LS-SCLC, Eastern Cooperative Oncology Group performance status of 0 to 2, and adequate organ function were eligible. HypoTRT of 55 Gy at 2.5 Gy per fraction over 30 days was given on the first day of the second or third cycle of chemotherapy. An etoposide/cisplatin regimen was given to 4 to 6 cycles. Patients who had a good response to initial treatment were offered prophylactic cranial irradiation. The primary endpoint was the 2-year progression-free survival rate. Results: Fifty-nine patients were enrolled from July 2007 through February 2012 (median age, 58 years; 86% male). The 2-year progression-free survival rate was 49.0% (95% confidence interval [CI] 35.3%-62.7%). Median survival time was 28.5 months (95% CI 9.0-48.0 months); the 2-year overall survival rate was 58.2% (95% CI 44.5%-71.9%). The 2-year local control rate was 76.4% (95% CI 63.7%-89.1%). The severe hematologic toxicities (grade 3 or 4) were leukopenia (32%), neutropenia (25%), and thrombocytopenia (15%). Acute esophagitis and pneumonitis of grade ≥3 occurred in 25% and 10% of the patients, respectively. Thirty-eight patients (64%) received prophylactic cranial irradiation. Conclusion: Our study showed that HypoTRT of 55 Gy at 2.5 Gy per fraction daily concurrently with etoposide/cisplatin chemotherapy has favorable survival and acceptable toxicity. This radiation schedule deserves further investigation in LS-SCLC.

    Shared decision-making (SDM) has been advocated as the preferred method of choosing a suitable treatment option. However, patient involvement in treatment decision-making is not yet common practice in the field of vascular surgery. The aim of this mixed-methods study was to explore patients' decision-making preferences and to investigate which facilitators and barriers patients perceive as important for the application of SDM in vascular surgery. Patients were invited to participate after visiting the vascular surgical outpatient clinic of an Academic Medical Center in the Netherlands. A treatment decision was made during the consultation for an abdominal aortic aneurysm or peripheral arterial occlusive disease. Patients filled in a number of questionnaires (quantitative part) and a random subgroup of patients participated in an in-depth interview (qualitative part). A total of 67 patients participated in this study. 58 per cent of them (n=39) indicated that they preferred a shared role in decision-making. In more than half of the patients (55%; n=37) their preferred role was in disagreement with what they had experienced. 31 per cent of the patients (n=21) preferred a more active role in the decision-making process than they had experienced. Patients indicated a good patient-doctor relationship as an important facilitator for the application of SDM. The vast majority of vascular surgical patients preferred, but did not experience a shared role in the decision-making process, although the concept of SDM was insufficiently clear to some patients. This emphasises the importance of explaining the concept of SDM and implementing it in the clinical encounter. Published by the BMJ Publishing Group Limited.

    The majority of costs associated with esophagectomy are related to the initial 3 days of hospital stay requiring intensive care unit stays, ventilator support, and intraoperative time. Additional costs arise from hospital-based services. The major cost increases are related to complications associated with the procedure. We attempted to define these costs and identify expense management by streamlining care through strict adherence to patient care maps, operative standardization, and rapid discharge planning to reduce variability. Utilizing methods of Kaizen philosophy we evaluated all processes related to the entire experience of esophageal resection. This process has taken over 5 years to achieve, with quality and cost being tracked over this time period. Cost analysis included expenses related to intensive care unit, anesthesia, disposables, and hospital services. Quality improvement measures were related to intraoperative complications, in-hospital complications, and postoperative outcomes. The Institutional Review Board approved the use of anonymous data from standard clinical practice because no additional treatment was planned (observational study). Utilizing a continuous process improvement methodology, a 43% reduction in cost per case has been achieved with a significant increase in contribution margin for esophagectomy. The length of stay has been reduced from 14 days to 5. With intraoperative and postoperative standardization the leak rate has dropped from 12% to less than 3% to no leaks in our current Kaizen modification of care in our last 64 patients. Utilizing lean manufacturing techniques and continuous process evaluation we have attempted to eliminate variability, standardized the phases of care resulting in improved outcomes, decreased length of stay, and improved contribution margins. These Kaizen improvements require continuous interventions, strict adherence to care maps, and input from all levels for quality improvements. Copyright © 2011 The

    Antimicrobial resistance is a public health challenge supplemented by inappropriate prescribing, especially for an upper respiratory tract infection in primary care. Patient/carer expectations have been identified as one of the main drivers for inappropriate antibiotics prescribing by primary care physicians. The aim of this study was to understand who is more likely to expect an antibiotic for an upper respiratory tract infection from their doctor and the reasons underlying it. This study used a sequential mixed methods approach: a nationally representative cross sectional survey ( n  = 1509) and four focus groups. The outcome of interest was expectation and demand for an antibiotic from a doctor when presenting with a cold or flu. The study found 19.5 % of survey respondents reported that they would expect the doctor to prescribe antibiotics for a cold or flu. People younger than 65 years of age, those who never attended university and those speaking a language other than English at home were more likely to expect or demand antibiotics for a cold or flu. People who knew that 'antibiotics don't kill viruses' and agreed that 'taking an antibiotic when one is not needed means they won't work in the future' were less likely to expect or demand antibiotics. The main reasons for expecting antibiotics were believing that antibiotics are an effective treatment for a cold or flu and that they shortened the duration and potential deterioration of their illness. The secondary reason centered around the value or return on investment for visiting a doctor when feeling unwell. Our study found that patients do not appear to feel they have a sufficiently strong incentive to consider the impact of their immediate use of antibiotics on antimicrobial resistance. The issue of antibiotic resistance needs to be explained and reframed as a more immediate health issue with dire consequences to ensure the success of future health campaigns.

    Full Text Available This paper presents an interior point algorithm to solve the multiperiod hydrothermal economic dispatch (HTED. The multiperiod HTED is a large scale nonlinear programming problem. Various optimization methods have been applied to the multiperiod HTED, but most neglect important network characteristics or require decomposition into thermal and hydro subproblems. The algorithm described here exploits the special bordered block diagonal structure and sparsity of the Newton system for the first order necessary conditions to result in a fast efficient algorithm that can account for all network aspects. Applying this new algorithm challenges a conventional method for the use of available hydro resources known as the peak shaving heuristic.

    To determine preferences among patients with type 2 diabetes for content and format of patient education. Using discrete choice methods, we surveyed patients about their preferences for patient education. We investigated preferred content and format regarding education on living well with diabetes, preventing complications, healthy eating, exercising, and psychosocial issues related to diabetes. We obtained usable responses from 2187 patients with type 2 diabetes. Acquiring competencies to live a fulfilling life with diabetes, adjust diet and exercise habits, and prevent complications was significantly more highly valued than was simply being informed about these topics. Patients preferred to be involved in the planning of their diabetes care and valued individually tailored content higher than prescheduled content. Women and younger patients found diet and exercise significantly more important than did men, and patients with poorly controlled diabetes valued all education and support more highly than did patients in better control. Patients with type 2 diabetes prefer to be actively involved in educational activities, to develop competencies to prevent and manage complications, and to involve their social network in supporting them. Future patient education should enhance participation and competence development and include relatives. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    To evaluate the effects of physical methods of reducing body temperature (ice pack and warm compression) in critically ill patients with fever. A randomized clinical trial involving 102 adult patients with tympanic temperature ≥ 38.3°C of an infectious focus, and randomized into three groups: Intervention I - ice pack associated with antipyretic; Intervention II - warm compress associated with antipyretic; and Control - antipyretic. Tympanic temperature was measured at 15 minute intervals for 3 hours. The effect of the interventions was evaluated through the Mann-Whitney test and Survival Analysis. "Effect size" calculation was carried out. Patients in the intervention groups I and II presented greater reduction in body temperature. The group of patients receiving intervention I presented tympanic temperature below 38.3°C at 45 minutes of monitoring, while the value for control group was lower than 38.3°C starting at 60 minutes, and those who received intervention II had values lower than 38.3°C at 75 minutes of monitoring. No statistically significant difference was found between the interventions, but with the intervention group I patients showed greater reduction in tympanic temperature compared to the other groups.

    Online consumer health information addresses health problems, self-care, disease prevention, and health care services and is intended for the general public. Using this information, people can improve their knowledge, participation in health decision-making, and health. However, there are no comprehensive instruments to evaluate the value of health information from a consumer perspective. We collaborated with information providers to develop and validate the Information Assessment Method for all (IAM4all) that can be used to collect feedback from information consumers (including patients), and to enable a two-way knowledge translation between information providers and consumers. Content validation steps were followed to develop the IAM4all questionnaire. The first version was based on a theoretical framework from information science, a critical literature review and prior work. Then, 16 laypersons were interviewed on their experience with online health information and specifically their impression of the IAM4all questionnaire. Based on the summaries and interpretations of interviews, questionnaire items were revised, added, and excluded, thus creating the second version of the questionnaire. Subsequently, a panel of 12 information specialists and 8 health researchers participated in an online survey to rate each questionnaire item for relevance, clarity, representativeness, and specificity. The result of this expert panel contributed to the third, current, version of the questionnaire. The current version of the IAM4all questionnaire is structured by four levels of outcomes of information seeking/receiving: situational relevance, cognitive impact, information use, and health benefits. Following the interviews and the expert panel survey, 9 questionnaire items were confirmed as relevant, clear, representative, and specific. To improve readability and accessibility for users with a lower level of literacy, 19 items were reworded and all inconsistencies in using a

    Thirty-eight patients with prostatic cancer treated with radiotherapy giving a mean dose of 60.7 Gy between 1992 and 1997 at Shikoku Cancer Center Hospital were reviewed and the treatment outcomes were investigated retrospectively. About two-third of the patients were treated with radiation by linear accelerator with 40 to 46 Gy to the whole pelvis and with 20 to 26 Gy boost to the prostate area and the other one-third were treated only to the prostate area. For almost patients, external beam radiotherapy in combination with endocrine therapy was used. The median duration of follow-up was 36 months. Overall 5-year survival and 5-year relapse-free survival rate were 65.8%, and 88.9%, respectively. Severe rectal late morbidity (over grade 3) according to RTOG grading system were seen in one (2.6%). Although the number of cases was rather small and the follow-up duration was rather short, conventional external beam radiotherapy in combination with endocrine therapy may contribute to the survival benefit of patients with prostatic cancer in aged 75 or older. Radiotherapy for elderly prostatic cancer patients should be treated with an effort to decrease the late morbidity and not to deteriorate the QOL of the patients, because many patients were died of other causes than cancer.

    A sensitive and specific radioimmunoassay has been developed for the measurement of serum Mb. Immunization of rabbit with human Mb yielded anti-Mb antibody which was purified by affinity chromatography. Human hemoglobin, CK, and the component of serum per se did not appear to cross-react with the antibody. Mb was radiolabeled by the chloramine T method. The radioimmunoassay method could detect as little as 0.3 ng of Mb and was not affected by hemolysis. Information is also given on precision, recovery, and specimen preservation. Mb levels could be detected in all of 120 normal adults, and the values ranged between 1 and 28 ng/ml (mean, 13.1 +- 6.1). No sex difference was observed. Levels were markedly elevated in all the patients with progressive muscular dystrophy, especially in the Duchenne type at the level of 40 to 1700 ng/ml. It was also noticed that about 70% of female gene carriers of Duchenne type had a slightly increased Mb level. An elevated serum Mb was also noted in polymyositis. In every case of acute myocardial infarction, serum Mb levels were increased, peak values ranging from 175 to 4400 ng/ml and averaging 1162 +- 287.9 Mb levels were elevated faster and peaked earlier (within 6 to 12 hr after the attack) than serum CK activity and returned to nearly normal range within 3 to 4 days. The increase in serum Mb was also noticed in shock and surgery. These data indicate that radioimmunoassay of Mb is a useful test for judging the myolytic state of myogenic myopathies and for early detection of myocardial infarction

    The purpose of this study is to investigate the satisfaction of patients who have already finished bar removal. Fifty-four patients with pectus excavatum underwent the Nuss procedure between July 2000 and December 2007 and the bar was removed in 41 of them at our hospital. A telephone questionnaire was administered to their parents or the patients (12 years old or older). The questions were as follows: self-assessment of the present thoracic form on a 5-point scale, whether it was good to have undergone the Nuss procedure (Y/N), whether the patient will recommend this procedure to another patient (Y/N). Thirty-nine patients responded to the questionnaire. Median age at the bar insertion was 83 months (range: 63-189 months). The bar was removed about 2 years after the initial operation. The median period after removal was 29 months ( range: 2-65 months). The mean point for the thoracic form was 4.2 (5 points: 20, 4 points: 11, 3 points: 5, 2 points: 3). Thirty-eight patients answered that they were satisfied with this procedure. Thirty-four patients answered that they would recommend this procedure to another patient. Eight patients reported that redepression occurred after bar removal. Six of them are under observation because their thoracic deformity is mild. Patients' satisfaction with the Nuss procedure was high. However, our study shows the possibility of post-removal recurrence. There seems to be a tendency for patients to assess their thoracic form more strictly than the doctors. (author)

    This study aimed to analyze the treatment and outcomes of older glioblastoma patients. Forty-four patients older than 70 years of age were referred to the Paul Strauss Center for chemotherapy and radiotherapy. The median age was 75.5 years old (range: 70–84), and the patients included 18 females and 26 males. The median Karnofsky index (KI) was 70%. The Charlson indices varied from 4 to 6. All of the patients underwent surgery. O{sub 6}-methylguanine–DNA methyltransferase (MGMT) methylation status was determined in 25 patients. All of the patients received radiation therapy. Thirty-eight patients adhered to a hypofractionated radiation therapy schedule and six patients to a normofractionated schedule. Neoadjuvant, concomitant and adjuvant chemotherapy regimens were administered to 12, 35 and 20 patients, respectively. At the time of this analysis, 41 patients had died. The median time to relapse was 6.7 months. Twenty-nine patients relapsed, and 10 patients received chemotherapy upon relapse. The median overall survival (OS) was 7.2 months and the one- and two-year OS rates were 32% and 12%, respectively. In a multivariate analysis, only the Karnofsky index was a prognostic factor. Hypofractionated radiotherapy and chemotherapy with temozolomide are feasible and acceptably tolerated in older patients. However, relevant prognostic factors are needed to optimize treatment proposals.

    Providing high service quality is one of the main functions of health systems. Measuring service quality is the basic prerequisite for improving quality. The aim of this study was to evaluate the quality of service in teaching hospitals using importance-performance analysis matrix. A descriptive-analytic study was conducted through a cross-sectional method in six academic hospitals of Qazvin, Iran, in 2012. A total of 360 patients contributed to the study. The sampling technique was stratified random sampling. Required data were collected based on a standard questionnaire (SERVQUAL). Data analysis was done through SPSS version 18 statistical software and importance-performance analysis matrix. The results showed a significant gap between importance and performance in all five dimensions of service quality (p quality gap and "responsiveness" had the lowest gap (1.97). Also, according to findings, reliability and assurance were in Quadrant (I), empathy was in Quadrant (II), and tangibles and responsiveness were in Quadrant (IV) of the importance-performance matrix. The negative gap in all dimensions of quality shows that quality improvement is necessary in all dimensions. Using quality and diagnosis measurement instruments such as importance-performance analysis will help hospital managers with planning of service quality improvement and achieving long-term goals.

    Stenosis and obstruction of the internal jugular vein (IJV) sometimes occur following modified radical neck dissection or selective neck dissection, in which the IJV is preserved. The objective of this study was to assess risk factors for stenosis or obstruction of the IJV following neck dissection. A total of 58 neck dissections performed in 51 patients by the same surgeon at Gunma University Hospital were retrospectively reviewed. The relationships of the patency of the IJV with gender, side of dissection, number of lymph node metastases, invasion out of the lymph node, radiotherapy, and reconstructive method were examined. The patency of the IJV was evaluated postoperatively using enhanced computed tomography. All cases with obstruction of the IJV received postoperative radiotherapy and neck dissection on the left side. Postoperative radiotherapy was a significant risk factor for obstruction of the IJV. Free flap reconstruction was not a risk factor for stenosis and obstruction. The rate of obstruction of the IJV was significantly decreased in cases with pectoral major musculocutaneous flap reconstruction or extended supraomohyoid neck dissection in which the muscle extensively covered the IJV.

    Purpose: 'Exoscopic' and endoscopic identification of colorectal pathologies via MRI. Methods: 5 patients (36-88 years), two normal and three with different colorectal pathologies (diverticular disease, polyps and carcinoma of the colon), were examined by MRI after colonoscopy. Subsequent to filling of the colon with a gadolinium-water mixture under MRI-monitoring, 3D-data sets of the colon were acquired in prone and supine positions over a 28 sec breathold interval. Subsequently multiplanar T 1 -weighted 2D-sequences were acquired before and following i.v. administration of Gd-DTPA (0.1 mmol/kg BW). All imaging was performed in the coronal orientation. The 3D-data were interactively analysed based on various displays: Maximum intensity projection (MIP), surface shadowed display (SSD), multiplanar reconstruction (MPR), virtual colonoscopy (VC). Results: All of the colorectal pathologies could be interactively diagnosed by MPR. On MIP images some pathologies were missed. VC presented the morphology of colon haustra as well as of all endoluminally growing lesions in a manner similar to endoscopy. The colon masses showed uptake of contrast media and could thus be differentiated from air or faeces. (orig./AJ) [de

    The aim of this study was to improve patient handoffs on the labor floor. A prospective cohort study of obstetrics residents at Montefiore Medical Center was performed between 2012 and 2014. Labor-floor handoffs were recorded before and after didactic sessions as well as after installation of whiteboards formatted with the mnemonic SWIFT (Subject, Why?, Issues, Fetus, Tasks). Handoff transcripts were evaluated by obstetricians blinded to timing and speaker identity. An intraclass correlation coefficient accounted for evaluator differences. Data analysis was by ordinal logistic regression, the generalized estimating equations method (correlated data), and Bonferroni adjustment (multiple comparisons). Forty-five handoffs were evaluated (15 each predidactics, postdidactics, and postwhiteboard revision). Higher completeness scores over time were noted for admission reason, labor concerns, and task list (not statistically significant). Comprehensive score increases prelecture to postwhiteboard were seen in handoff clarity (2.81 versus 2.91) and overall quality (2.77 versus 2.81) (not statistically significant). A subanalysis of four residents who gave multiple handoffs over different periods revealed few significant changes over time. Greater interevaluator consistency was noted with more objective elements. The mnemonic SWIFT, with formalized curricula for obstetrical resident training focusing on new learners and increased faculty involvement and reinforcement, may result in improvement of handoffs on the labor floor.

    Background: Recently, we described a model system which included corrections of high-resolution computed tomography (HRCT) bronchial measurements based on the adjusted subpixel method (ASM). Objective: To verify the clinical application of ASM by comparing bronchial measurements obtained by means of the traditional eye-driven method, subpixel method alone and ASM in a group comprised of bronchial asthma patients and healthy individuals. Methods: The study included 30 bronchial asthma patients and the control group comprised of 20 volunteers with no symptoms of asthma. The lowest internal and external diameters of the bronchial cross-sections (ID and ED) and their derivative parameters were determined in HRCT scans using: (1) traditional eye-driven method, (2) subpixel technique, and (3) ASM. Results: In the case of the eye-driven method, lower ID values along with lower bronchial lumen area and its percentage ratio to total bronchial area were basic parameters that differed between asthma patients and healthy controls. In the case of the subpixel method and ASM, both groups were not significantly different in terms of ID. Significant differences were observed in values of ED and total bronchial area with both parameters being significantly higher in asthma patients. Compared to ASM, the eye-driven method overstated the values of ID and ED by about 30% and 10% respectively, while understating bronchial wall thickness by about 18%. Conclusions: Results obtained in this study suggest that the traditional eye-driven method of HRCT-based measurement of bronchial tree components probably overstates the degree of bronchial patency in asthma patients.

    To facilitate future pharmacokinetic studies of combination treatments against leishmaniasis in remote regions in which the disease is endemic, a simple cheap sampling method is required for miltefosine quantification. The aims of this study were to validate a liquid chromatography-tandem mass spectrometry method to quantify miltefosine in dried blood spot (DBS) samples and to validate its use with Ethiopian patients with visceral leishmaniasis (VL). Since hematocrit (Ht) levels are typically severely decreased in VL patients, returning to normal during treatment, the method was evaluated over a range of clinically relevant Ht values. Miltefosine was extracted from DBS samples using a simple method of pretreatment with methanol, resulting in >97% recovery. The method was validated over a calibration range of 10 to 2,000 ng/ml, and accuracy and precision were within ±11.2% and ≤7.0% (≤19.1% at the lower limit of quantification), respectively. The method was accurate and precise for blood spot volumes between 10 and 30 μl and for Ht levels of 20 to 35%, although a linear effect of Ht levels on miltefosine quantification was observed in the bioanalytical validation. DBS samples were stable for at least 162 days at 37°C. Clinical validation of the method using paired DBS and plasma samples from 16 VL patients showed a median observed DBS/plasma miltefosine concentration ratio of 0.99, with good correlation (Pearson's r = 0.946). Correcting for patient-specific Ht levels did not further improve the concordance between the sampling methods. This successfully validated method to quantify miltefosine in DBS samples was demonstrated to be a valid and practical alternative to venous blood sampling that can be applied in future miltefosine pharmacokinetic studies with leishmaniasis patients, without Ht correction.

    Conclusions: The 6 month manegement of asthma in the actual clinical setting, including regular ICS use, might have a harmful influence on the bone status of female asthmatic patients. It may be necessary to manage and treat female patients for potent corticosteroid-induced osteoporosis, although further analyses of bone status in asthma patient ICS users will be required.

    The ratio between plasma kynurenine (Kyn) and tryptophan (Trp) serves as a marker of indoleamine 2,3-dioxygenase, a critical immunomodulatory molecule. Simultaneous detection of the two markers may be performed using high-pressure liquid chromatography (HPLC). However, for uremic patients, the conventional detection method may be affected by a range of accumulated toxins. The current study aimed to establish a method for the simultaneous measurement of Kyn and Trp in patients following maintenance hemodialysis via HPLC-ultraviolet detection. The procedure involved the use of a SinoChrom ODS-BP C18 column (4.6×150 mm; inner diameter, 4.5 μm) and a mobile phase of 15 mmol/l sodium acetate acetic acid solution (containing 5% acetonitrile, pH 4.8). The modified method was verified using plasma samples from 10 healthy controls and 91 maintenance hemodialysis patients. The results demonstrated that the modified method was successful in simultaneously detecting the concentrations of Trp and Kyn in the healthy controls and maintenance hemodialysis patients. The method is simple, fast, accurate and suitable for clinical and research purposes in maintenance hemodialysis patients. PMID:24669249

    Full Text Available Abstract Background Advances in miniature sensor technology have led to the development of wearable systems that allow one to monitor motor activities in the field. A variety of classifiers have been proposed in the past, but little has been done toward developing systematic approaches to assess the feasibility of discriminating the motor tasks of interest and to guide the choice of the classifier architecture. Methods A technique is introduced to address this problem according to a hierarchical framework and its use is demonstrated for the application of detecting motor activities in patients with chronic obstructive pulmonary disease (COPD undergoing pulmonary rehabilitation. Accelerometers were used to collect data for 10 different classes of activity. Features were extracted to capture essential properties of the data set and reduce the dimensionality of the problem at hand. Cluster measures were utilized to find natural groupings in the data set and then construct a hierarchy of the relationships between clusters to guide the process of merging clusters that are too similar to distinguish reliably. It provides a means to assess whether the benefits of merging for performance of a classifier outweigh the loss of resolution incurred through merging. Results Analysis of the COPD data set demonstrated that motor tasks related to ambulation can be reliably discriminated from tasks performed in a seated position with the legs in motion or stationary using two features derived from one accelerometer. Classifying motor tasks within the category of activities related to ambulation requires more advanced techniques. While in certain cases all the tasks could be accurately classified, in others merging clusters associated with different motor tasks was necessary. When merging clusters, it was found that the proposed method could lead to more than 12% improvement in classifier accuracy while retaining resolution of 4 tasks. Conclusion Hierarchical

    To evaluate the effectiveness of internal auditing in hospital care focussed on improving patient safety. A before-and-after mixed-method evaluation study was carried out in eight departments of a university medical center in the Netherlands. Internal auditing and feedback focussed on improving patient safety. The effect of internal auditing was assessed 15 months after the audit, using linear mixed models, on the patient, professional, team and departmental levels. The measurement methods were patient record review on adverse events (AEs), surveys regarding patient experiences, safety culture and team climate, analysis of administrative hospital data (standardized mortality rate, SMR) and safety walk rounds (SWRs) to observe frontline care processes on safety. The AE rate decreased from 36.1% to 31.3% and the preventable AE rate from 5.5% to 3.6%; however, the differences before and after auditing were not statistically significant. The patient-reported experience measures regarding patient safety improved slightly over time (P audit. The SWRs showed that medication safety and information security were improved (P auditing was associated with improved patient experiences and observed safety on wards. No effects were found on adverse outcomes, safety culture and team climate 15 months after the internal audit.

    Objective: To discuss the clinical value of coronary artery imaging using 64-slice CT in patient with atrial fibrillation. Methods: All the cardiac volume data of 31 patients with atrial fibrillation were reconstructed using absolute time method. The images of 12 patients. The images of 31 patients who undeiwent contrast-enhanced CT coronary angiography were evaluated. The presence of stenosis on each segment of coronary arteries was recorded and their degree of stenosis was measured using the vessel analysis software.. The results of conventional coronary angiography (CAG) of the 10 patients were compared with CT coronary angiography. Results: The image quality of 364 coronary vessel segments on the images from 31 patients was evaluated and defined as excellent, fine, moderate or poor. The image quality was excellent, fine, moderate and poor in 194(53.3%), 82(22.5%), 41(11.3%) and 47(12.9%) vessel segments. Comparison was carried out between CTA findings and CAG findings of the 125 segments of the coronary arteries in the 10 patients who underwent CAG. The sensitivity and specificity of CTA for diagnosing vessel with stenosis (≥ 50% narrowing) was 85%(17/20) and 95.2% (100/105). Conclusion: Coronary artery imaging using 64-slice CT is useful in patient with atrial fibrillation. (authors)

    Effective patient-family communication can reduce patients' psychosocial distress and relieve family members' current suffering and their subsequent grief. However, terminally ill patients and their family members often experience great difficulty in communicating their true feelings, concerns, and needs to each other. To develop a novel means of facilitating meaningful conversations for palliative patients and family members, coined Dignity Talk, explore anticipated benefits and challenges of using Dignity Talk, and solicit suggestions for protocol improvement. A convergent parallel mixed-methods design. Dignity Talk, a self-administered question list, was designed to prompt end-of-life conversations, adapted from the Dignity Therapy question framework. Participants were surveyed to evaluate the Dignity Talk question framework. Data were analyzed using qualitative and quantitative methods. A total of 20 palliative patients, 20 family members, and 34 healthcare providers were recruited from two inpatient palliative care units in Winnipeg, Canada. Most Dignity Talk questions were endorsed by the majority of patients and families (>70%). Dignity Talk was revised to be convenient and flexible to use, broadly accessible, clearly stated, and sensitively worded. Participants felt Dignity Talk would be valuable in promoting conversations, enhancing family connections and relationships, enhancing patient sense of value and dignity, promoting effective interaction, and attending to unfinished business. Participants suggested that patients and family members be given latitude to respond only to questions that are meaningful to them and within their emotional capacity to broach. Dignity Talk may provide a gentle means of facilitating important end-of-life conversations.

    Full Text Available Total hip arthroplasty (THA has improved the quality of life of patients with hip arthritis. Orthopedic community is striving for excellence to improve surgical techniques and postoperative care. Despite these efforts, patients continue facing postoperative complications. In particular, patients with rheumatoid arthritis display a higher risk of certain complications such as dislocation, periprosthetic infection, and shorter prosthesis durability. In this review we present the current knowledge of hip arthroplasty in patients with rheumatoid arthritis with more insight into common practices and interventions directed at enhancing recovery of these patients and current shortfalls.

    2011-01-01

    Full Text Available Abstract Background Comprehensive "Total Pain" assessments of patients' end-of-life needs are critical for providing improved patient-clinician communication, assessing needs, and offering high quality palliative care. However, patients' needs-based research methodologies and findings remain highly diverse with their lack of consensus preventing optimum needs assessments and care planning. Mixed-methods is an underused yet robust "patient-based" approach for reported lived experiences to map both the incidence and prevalence of what patients perceive as important end of life needs. Methods Findings often include methodological artifacts and their own selection bias. Moving beyond diverse findings therefore requires revisiting methodological choices. A mixed methods research cross-sectional design is therefore used to reduce limitations inherent in both qualitative and quantitative methodologies. Audio-taped phenomenological "thinking aloud" interviews of a purposive sample of 30 hospice patients are used to identify their vocabulary for communicating perceptions of end-of-life needs. Grounded theory procedures assisted by QSR-NVivo software is then used for discovering domains of needs embedded in the interview narratives. Summary findings are translated into quantified format for presentation and analytical purposes. Results Findings from this mixed-methods feasibility study indicate patients' narratives represent 7 core domains of end-of-life needs. These are (1 time, (2 social, (3 physiological, (4 death and dying, (5 safety, (6 spirituality, (7 change & adaptation. The prevalence, rather than just the occurrence, of patients' reported needs provides further insight into their relative importance. Conclusion Patients' perceptions of end-of-life needs are multidimensional, often ambiguous and uncertain. Mixed methodology appears to hold considerable promise for unpacking both the occurrence and prevalence of cognitive structures represented by

    The objective of this study was to demonstrate the effectiveness of rugoscopy as a human identification method, even when the patient is submitted to rapid palatal expansion, which in theory would introduce doubt. With this intent, the Rugoscopic Identity was obtained for each subject using the classification formula proposed by Santos based on the intra-oral casts made before and after treatment from patients who were subjected to palatal expansion. The casts were labeled with the patients' initials and randomly arranged for studying. The palatine rugae kept the same patterns in every case studied. The technical error of the intra-evaluator measurement provided a confidence interval of 95%, making rugoscopy a reliable identification method for patients who were submitted to rapid palatal expansion, because even in the presence of intra-oral changes owing to the use of palatal expanders, the palatine rugae retained the biological and technical requirements for the human identification process. © 2012 American Academy of Forensic Sciences.

    Recently, we described a model system which included corrections of high-resolution computed tomography (HRCT) bronchial measurements based on the adjusted subpixel method (ASM). To verify the clinical application of ASM by comparing bronchial measurements obtained by means of the traditional eye-driven method, subpixel method alone and ASM in a group comprised of bronchial asthma patients and healthy individuals. The study included 30 bronchial asthma patients and the control group comprised of 20 volunteers with no symptoms of asthma. The lowest internal and external diameters of the bronchial cross-sections (ID and ED) and their derivative parameters were determined in HRCT scans using: (1) traditional eye-driven method, (2) subpixel technique, and (3) ASM. In the case of the eye-driven method, lower ID values along with lower bronchial lumen area and its percentage ratio to total bronchial area were basic parameters that differed between asthma patients and healthy controls. In the case of the subpixel method and ASM, both groups were not significantly different in terms of ID. Significant differences were observed in values of ED and total bronchial area with both parameters being significantly higher in asthma patients. Compared to ASM, the eye-driven method overstated the values of ID and ED by about 30% and 10% respectively, while understating bronchial wall thickness by about 18%. Results obtained in this study suggest that the traditional eye-driven method of HRCT-based measurement of bronchial tree components probably overstates the degree of bronchial patency in asthma patients.

    While accrediting organizations require AuD programs to provide evidence that their students are able to demonstrate knowledge and competencies in specific content areas, there are no generally accepted mechanisms for the assessment and the measurement of these proficiencies. We propose that AuD programs consider developing standardized patient (SP) cases in order to develop consistent summative assessment programs within and across universities. The purpose of this article is to provide a framework for establishing SP programs to evaluate competencies in AuD students by detailing the history of SP cases and their use, developing a rationale for this method of assessment, and outlining the steps for writing and implementing SP cases. Literature review. SPs have been used to assess clinical competence in medical students for over 50 yr. The prevalence of SP assessment in allied health professions (e.g., dentistry, psychology, pharmacy) has increased over the last two decades but has only gained a limited following in audiology. SP assessment has been implemented in medical education using the Objective Structured Clinical Examination, a multistation, timed exam that uses fictional cases to assess students' clinical abilities. To date, only one published report has been completed that evaluates the use of SPs to assess clinical abilities in audiology students. This article expands upon the work of English et al (2007) and their efforts to use SPs to evaluate counseling abilities. To this end, we describe the steps necessary to write a case, procedures to determine performance requirements, and the need to develop remediation plans. As an example, we include a case that we have developed in order to evaluate vestibular assessment and patient communication skills. Utilizing SP assessment in audiology education would provide useful means to evaluate competence in a uniform way. Future research is necessary to develop reliable and valid cases that may be implemented

    Cognitive and behavioral impairments are common in patients with abnormal thyroid function; these impairments cause a reduction in their quality of life. The current study investigates the decision making performance in patients with hyperthyroidism to explore the possible mechanism of their cognitive and behavioral impairments. Thirty-eight patients with hyperthyroidism and forty healthy control subjects were recruited to perform the Iowa Gambling Task (IGT), which assessed decision making under ambiguous conditions. Patients with hyperthyroidism had a higher score on the Zung Self-Rating Anxiety Scale (Z-SAS), and exhibited poorer executive function and IGT performance than did healthy control subjects. The patients preferred to choose decks with a high immediate reward, despite a higher future punishment, and were not capable of effectively using feedback information from previous choices. No clinical characteristics were associated with the total net score of the IGT in the current study. Patients with hyperthyroidism had decision-making impairment under ambiguous conditions. The deficits may result from frontal cortex and limbic system metabolic disorders and dopamine dysfunction.

    To investigate brain lesions and their locations in patients with central vertigo, as seen on MR imaging. We retrospectively reviewed MR images of 85 patients with central type vertigo diagnosed on the basis of clinical symptoms and vestibular function test(VFT), and analyzed lesions fand their locations. Those located along the known central vestibular pathway were included in our study. In 29 of 85 patients(34%), lesions considered to be associated with central vertigo were detected on MR imaging. These included infarction(18 patients), hemorrhage(5), tumor(2), cavernous angioma(1), cerebellopontine angle cyst(1), tuberous sclerosis(1) and olivopontocerebellar atrophy (1);they were located in the parietal lobe(6 patients), the lateral medulla(5), the pons(5), the middle cerebellar peduncle(4), the corona radiata(3), and the cerebellar vermis(3). Thirty-eight cases showed high signal intensity lesions in deep cerebral matter, the basal ganglia, and pons but these were considered to be unrelated to central vertigo. MR imaging could be a useful tool for the evaluation of patients with central vertigo.=20

    Objective: To explore the effect of different anesthesia methods on the levels of plasma neuropeptides during the peri-operative period in patients with hypertension. Methods: Ninety hypertensive patients undergoing upper abdominal operations were randomly allocated to equal divided epidural anesthesia, general anesthesia and combined Groups. Plasma neuropeptide Y(NPY) concentrations were measured before anesthesia, at 15 min after anesthesia, 20 min after operation and 10 min after completion of the operation. Results: BP, HR and NPY were significantly changed in both E group and G group after anesthesia and operation (compared vs before anesthesia, p<0.01). BP, HR and NPY were significantly changed in C group after operation compared with those in both E and G group (p<0.05) . Conclusion: The combined anesthesia method is effective in inhibits the stress r
