Full Text Available High-utility sequential pattern mining (HUSPM has become an important issue in the field of data mining. Several HUSPM algorithms have been designed to mine high-utility sequential patterns (HUPSPs. They have been applied in several real-life situations such as for consumer behavior analysis and event detection in sensor networks. Nonetheless, most studies on HUSPM have focused on mining HUPSPs in precise data. But in real-life, uncertainty is an important factor as data is collected using various types of sensors that are more or less accurate. Hence, data collected in a real-life database can be annotated with existing probabilities. This paper presents a novel pattern mining framework called high utility-probability sequential pattern mining (HUPSPM for mining high utility-probability sequential patterns (HUPSPs in uncertain sequence databases. A baseline algorithm with three optional pruning strategies is presented to mine HUPSPs. Moroever, to speed up the mining process, a projection mechanism is designed to create a database projection for each processed sequence, which is smaller than the original database. Thus, the number of unpromising candidates can be greatly reduced, as well as the execution time for mining HUPSPs. Substantial experiments both on real-life and synthetic datasets show that the designed algorithm performs well in terms of runtime, number of candidates, memory usage, and scalability for different minimum utility and minimum probability thresholds.

Drug utilization studies are important for the optimization of drug therapy and have received a great attention in recent years. Most of the information on drug use patterns has been derived from studies in modern Western medicines; however, studies regarding the drug utilization of traditional Chinese medicine (CM) are few. The present study was the first clinical research to evaluate the drug utilization patterns of Chinese herbal medicines in a general hospital in Taiwan. Data were collected prospectively from the patients attending the Traditional Medicine Center of Taipei Veteran General Hospital under CM drug treatments. The study was carried out over a period of 1 year, from January 2002 to December 2002. Core drug use indicators, such as the average number of drugs per prescriptions, the dosing frequency of prescriptions, and the most common prescribed CM herbs and formulae were evaluated. The primary diagnosis and the CM drugs prescribed for were also revealed. All data were analyzed by descriptive statistics. A total of 10 737 patients, representing 52 255 CM drugs, were screened during the study period. Regarding the prescriptions, the average number of drugs per prescription was 4.87 and 37.21% of prescriptions were composed by five drugs. Most of prescriptions (91.38%) were prescribed for three times a day. The most often prescribed Chinese herb was Hong-Hwa (5.76%) and the most common Chinese herbal formula was Jia-Wey-Shiau-Yau-San (3.80%). The most frequent main diagnosis was insomnia (15.58%), followed by menopause (5.22%) and constipation (5.09%). The survey revealed the drug use pattern of CMs in a general hospital. The majority of CM prescriptions were composed by 3-6 drugs and often prescribed for three times a day. Generally, the rational drug uses of CM drugs were provided with respect to the various diagnoses. (c) 2005 John Wiley & Sons, Ltd.

Patients with resectable colorectal lung oligometastasis (CLOM) demonstrate a heterogeneous oncological outcome. However, the parameters for predicting tumor aggressiveness have not yet been fully investigated in CLOM. This study was performed to determine the prognostic value of histological growth patterns in patients who underwent surgery for CLOM. The study included 92 patients who were diagnosed with CLOM among the first resection cases. CLOMs grow according to three histological patterns: aerogenous, pushing, and desmoplastic patterns. The growth patterns were evaluated on archival hematoxylin and eosin-stained tissue sections. The aerogenous pattern was found in 29.4% (n=27) of patients, the pushing pattern in 34.7% (n=32), the desmoplastic pattern in 6.5% (n=6), and a mix of two growth patterns in 29.4% (n=27). The size of the aerogenous pattern was significantly smaller than that of metastases with other patterns (p=.033). Kaplan-Meier analysis demonstrated that patients showing an aerogenous pattern appeared to have a poorer prognosis, which was calculated from the time of diagnosis of the CLOM (p=.044). The 5-year survival rate from the diagnosis of colorectal cancer tended to be lower in patients with an aerogenous pattern than in those who had a non-aerogenous pattern; however, the difference was marginally significant (p=.051). In the multivariate Cox analysis, the aerogenous pattern appeared as an independent predictor of poor overall survival (hazard ratio, 3.122; 95% confidence interval, 1.196 to 8.145; p=.020). These results suggest that the growth patterns may play a part as a histology-based prognostic parameter for patients with CLOM.

Comorbidities adversely impact heart failure (HF) outcomes. Telehealth can assist healthcare providers, especially nurses, in guiding their patients to follow the HF regimen. However, factors, including comorbidity patterns, that act in combination with telehealth to reduce home care nursing utilization are still unclear. The purpose of this article was to examine the association of the comorbidity characteristics of HF patients with nursing utilization along with withdrawal from telehealth service during an episode of tele-home care. A descriptive, correlational study design using retrospective chart review was used. The sample comprised Medicare patients admitted to a New England home care agency who had HF as a diagnosis and had used telehealth from 2008 to 2010. The electronic documentation at the home care agency served as the data source, which included Outcome and Assessment Information Set data of patients with HF. Logistic and multiple regression analyses were used to analyze data. The sample consisted of 403 participants, of whom 70% were older than 75 years, 55% were female, and 94% were white. Comorbidities averaged 5.19 (SD, 1.92), ranging from 1 to 11, and nearly 40% of the participants had 5 or more comorbidities. The mean (SD) nursing contacts in the sample was 9.9 (4.7), ranging from 1 to 26, and 52 (12.7%) patients withdrew from telehealth service. For patients with HF on telehealth, comorbidity characteristics of anemia, anxiety, musculoskeletal, and depression were significantly associated with nursing utilization patterns, and renal failure, cancer, and depression comorbidities were significantly associated with withdrawal from telehealth service. Knowledge of the association of comorbidity characteristics with the home care service utilization patterns of patients with HF on telehealth can assist the home health nurse to develop a tailored care plan that attains optimal patient outcomes. Knowledge of such associations would also focus home

Full Text Available Dipeptidyl-4 (DPP-4 inhibitors are oral antidiabetic agents recently introduced to Malaysia. Thus, limited data is available on their utilization patterns and factors associated with their use. This study aims to analyse the utilization patterns of DPP-4 inhibitors, factors that influenced the choice of agent, and the rationale for treatment with DPP-4 inhibitors in patients with type 2 diabetes mellitus. This retrospective study was conducted to address the utilization pattern of DPP-4 inhibitors and factors that influence choice in type 2 diabetes mellitus patients. 299 subjects taking either sitagliptin or vildagliptin from September 2008 to September 2012 were included in the study. Sitagliptin was more frequently prescribed than vildagliptin. Of the patients prescribed DPP-4 inhibitors, 95% received combinations of these and other agents, whereas only 5% were prescribed DPP-4 inhibitors as monotherapy. Factors affecting the utilization of DPP-4 inhibitors included age (P=0.049 and concomitant use of beta blockers (P=0.045 and aspirin (P=0.008. Early identification of factors associated with DPP-4 inhibitors is essential to enhance quality use of the drugs.

Heavy menstrual bleeding (HMB) is a highly prevalent condition, characterized by excessive menstrual blood loss and cramping, that interferes with activities of daily life. The aim of this study was to investigate treatment patterns in HMB in Japan, and to assess healthcare resource utilization and costs among women newly-diagnosed with the condition. This study retrospectively analyzed health insurance data available in the Japan Medical Data Center (JMDC) database on women aged 18-49 years who were newly-diagnosed with primary or secondary HMB. Treatment patterns were analyzed, and healthcare utilization and costs were evaluated and compared to matched controls. The study included a total of 635 patients, 210 with primary HMB and 425 with secondary HMB. In the primary HMB cohort, 60.0% of patients received one or more pharmacological or surgical treatments, compared with 76.2% in the secondary HMB cohort. The most commonly prescribed medications in all patients were hemostatic agents (28.7%), traditional Chinese medicine (TCM) (12.1%), and low-dose estrogen progestins (LEPs) (10.1%). After adjustment for patient baseline characteristics, healthcare costs were 1.93-times higher in primary HMB cases (p < .0001) and 4.44-times higher in secondary HMB cases (p < .0001) vs healthy controls. Outpatient care was the main cost driver. The main limitations of this study are related to its retrospective nature, and the fact that only reimbursed medications were captured in the source database. A substantial proportion of HMB patients did not receive the recommended treatments. Healthcare costs were considerably increased in the presence of an HMB diagnosis.

The incidence of tuberculosis (TB) in end-stage renal disease is significantly higher than that in the general population. Among those with kidney dysfunction, anti-TB treatment is associated with increased side effects, but the effect on healthcare utilization is unknown. Methods/Aim: To assess patient-reported symptoms, adverse effects and describe changes in healthcare utilization patterns during treatment for TB, we conducted a case series (n = 12) of patients receiving maintenance hemodialysis (HD) from Mayo Clinic Dialysis Services and concurrent drug therapy for TB from January 2002 through May 2014. Healthcare utilization (hospitalizations and emergency department (ED) visits independent of hospital admission) was compared before and during treatment. Patients were treated for latent (n = 7) or active (n = 5) TB. The majority of patients with latent disease were treated with isoniazid (n = 5, 71%), while active-disease patients received a 4-drug regimen. Adverse effects were reported in 83% of patients. Compared to measurements prior to drug initiation, serum albumin and dialysis weights were similar at 3 months. Commonly reported anti-TB drug toxicities were described. More than half (58%) of the patients were hospitalized at least once. No ED or hospital admissions occurred in the period prior to drug therapy, but healthcare utilization increased during treatment in the latent disease group (hospitalization rate per person-month: pre 0 vs. post 1). Among HD patients, anti-TB therapy is associated with frequently reported symptoms and increased healthcare utilization. Among this subset, patients receiving treatment for latent disease may be those with greatest increase in healthcare use. Careful monitoring and early complication detection may help optimize medication adherence and minimize hospitalizations. © 2016 S. Karger AG, Basel.

Full Text Available Colloidal quantum dots (QDs with properties that can be tuned by size, shape, and composition are promising for the next generation of photonic and electronic devices. However, utilization of these materials in such devices is hindered by the limited compatibility of established semiconductor processing techniques. In this context, patterning of QD films formed from colloidal solutions is a critical challenge and alternative methods are currently being developed for the broader adoption of colloidal QDs in functional devices. Here, we present a solvent-free approach to patterning QD films by utilizing a shape memory polymer (SMP. The high pull-off force of the SMP below glass transition temperature (Tg in conjunction with the conformal contact at elevated temperatures (above Tg enables large-area, rate-independent, fine patterning while preserving desired properties of QDs.

The aim of this paper was to analyze medical utilization patterns of female patients with anorexia nervosa before their first inpatient care visit for anorexia nervosa using the National Health Insurance Research Database (NHIRD) of Taiwan. We selected female anorexia nervosa patients (n=239) and control participants hospitalized for peptic ulcers (n=478) or appendectomy (n=478) who were matched by age and incident year from two subsets of the NHIRD. The number of visits, specialists, diagnosis distribution, and selected procedures used in ambulatory services during the 2-year period before the index admission were identified and compared. Healthcare service expenditures were also analyzed. Compared to the control groups, the female anorexia nervosa patients used more outpatient services (anorexia nervosa, 58.6±45.0 visits; peptic ulcers, 45.3±37.3 visits; appendectomy, 32.5±26.0 visits), mainly due to psychiatric visits. Anorexia nervosa patients were more likely to have received a diagnosis of digestive, endocrine/metabolic, and mental disorders than patients in the control groups. Although nearly equal percentages of patients in the three groups had obtained a diagnosis of a digestive disease, anorexia nervosa patients received digestive disease diagnoses with greater frequency. We posit that the various physical symptoms of anorexia nervosa patients and physicians' low level of suspicion of anorexia nervosa led to delayed diagnoses and greater medical utilization than that of the controls groups. Education to raise awareness of anorexia nervosa and other eating disorders among physicians is warranted. Copyright © 2017 Elsevier Inc. All rights reserved.

The purpose of the study was to compare patterns of utilization and charges generated by medical doctors (MDs), doctors of chiropractic (DCs), and physical therapists (PTs) for the treatment of headache in North Carolina. Retrospective analysis of claims data from the North Carolina State Health Plan for Teachers and State Employees from 2000 to 2009. Data were extracted from Blue Cross Blue Shield of North Carolina for the North Carolina State Health Plan using International Classification of Diseases, Ninth Revision, diagnostic codes for headache. The claims were separated by individual provider type, combination of provider types, and referral patterns. The majority of patients and claims were in the MD-only or MD plus referral patterns. Chiropractic patterns represented less than 10% of patients. Care patterns with single-provider types and no referrals incurred the least charges on average for headache. When care did not include referral providers or services, MD with DC care was generally less expensive than MD care with PT. However, when combined with referral care, MD care with PT was generally less expensive. Compared with MD-only care, risk-adjusted charges (available 2006-2009) for patients in the middle risk quintile were significantly less for DC-only care. Utilization and expenditures for headache treatment increased from 2000 to 2009 across all provider groups. MD care represented the majority of total allowed charges in this study. MD care and DC care, alone or in combination, were overall the least expensive patterns of headache care. Risk-adjusted charges were significantly less for DC-only care.

To describe clinical and resource utilization patterns in patients with refractory neuropathic pain (NeP) who were prescribed pregabalin for the first time in routine medical practice in primary care settings. Post-hoc analysis of a 12-week prospective observational study including pregabalin naïve adult patients with refractory chronic NeP of at least 6-months duration. Self-reported pain intensity, disability, sleep disturbances, symptoms of anxiety and depression, disability, health-related quality of life (HRQoL), health care resource utilization, and corresponding costs were assessed in this post-hoc analysis. One thousand three hundred fifty-four patients were enrolled in the study, and three treatment groups were identified: (1) 598 patients replaced prior pain treatments with pregabalin as monotherapy; (2) 589 added pregabalin to their existing pain treatments; and (3) 167 other pain treatments were prescribed according with physician routine medical practice. Statistically significant differences were reported at baseline for intensity of pain, patient disability, severity of depressive symptoms, and HRQoL (P use of direct and indirect resources vs the other groups, resulting in significantly higher quarterly overall costs per patient: €2,397 (2,308), €2,470 (1,857), and €3,110 (2,496), respectively (P < 0.001). These findings suggest that primary care physicians chose pregabalin as an option for treating refractory patients who tended to have much more severe NeP profiles, costing society more than when they chose other therapeutic strategies not including pregabalin.

Sentinel lymph node biopsy is used to stage Merkel cell carcinoma, but its prognostic value has been questioned. Furthermore, predictors of outcome in sentinel lymph node positive Merkel cell carcinoma patients are poorly defined. In breast carcinoma, isolated immunohistochemically positive tumor cells have no impact, but in melanoma they are considered significant. The significance of sentinel lymph node metastasis tumor burden (including isolated tumor cells) and pattern of involvement in Merkel cell carcinoma are unknown. In this study, 64 Merkel cell carcinomas involving sentinel lymph nodes and corresponding immunohistochemical stains were reviewed and clinicopathological predictors of outcome were sought. Five metastatic patterns were identified: (1) sheet-like (n=38, 59%); (2) non-solid parafollicular (n=4, 6%); (3) sinusoidal, (n=11, 17%); (4) perivascular hilar (n=1, 2%); and (5) rare scattered parenchymal cells (n=10, 16%). At the time of follow-up, 30/63 (48%) patients had died with 21 (33%) attributable to Merkel cell carcinoma. Patients with pattern 1 metastases had poorer overall survival compared with patients with patterns 2-5 metastases (P=0.03), with 22/30 (73%) deaths occurring in pattern 1 patients. Three (10%) deaths occurred in patients showing pattern 5, all of whom were immunosuppressed. Four (13%) deaths occurred in pattern 3 patients and 1 (3%) death occurred in a pattern 2 patient. In multivariable analysis, the number of positive sentinel lymph nodes (1 or 2 versus >2, PMerkel cell carcinoma, the pattern of sentinel lymph node involvement provides important prognostic information and utilizing this data with other clinicopathological features facilitates risk stratification of Merkel cell carcinoma patients who may have management implications.

Full Text Available Abstract Objective Few studies have been published on health care utilization in Crohn's disease and the influence of psychological treatment on high utilizers. Methods The present sub study of a prospective multi center investigation conducted in 87 of 488 consecutive Crohn's disease (CD patients was designed to investigate the influence of the course of Crohn's disease on health care utilization (hospital days (HD and sick leave days (SLD collected by German insurance companies and to examine the conditions of high-utilizing patients. Predictors of health care utilization should be selected. Based on a standardized somatic treatment, high health care utilizing patients of the psychotherapy and control groups should be compared before and after a one-year treatment. Results Multivariate regression analysis identified disease activity at randomization as an important predictor of the clinical course (r2 = 0.28, p 2 = 0.15, p = 0.09. The patients' level of anxiety, depression and lack of control at randomization predicted their health-related quality of life at the end of the study (r2 = 0.51, p 2 = 0.22, p Among high utilizers, a significantly greater drop in HD (p Conclusion The course of Crohn's disease is influenced by psychological as well as somatic factors; especially depression seems important here. A significant drop of health care utilization demonstrates the benefit of psychological treatment in the subgroup of high-utilizing CD patients. Further studies are needed to replicate the findings of the clinical outcome in this CD subgroup.

Delamater, Paul L; Shortridge, Ashton M; Messina, Joseph P

2013-08-22

Community-based health care planning and regulation necessitates grouping facilities and areal units into regions of similar health care use. Limited research has explored the methodologies used in creating these regions. We offer a new methodology that clusters facilities based on similarities in patient utilization patterns and geographic location. Our case study focused on Hospital Groups in Michigan, the allocation units used for predicting future inpatient hospital bed demand in the state's Bed Need Methodology. The scientific, practical, and political concerns that were considered throughout the formulation and development of the methodology are detailed. The clustering methodology employs a 2-step K-means + Ward's clustering algorithm to group hospitals. The final number of clusters is selected using a heuristic that integrates both a statistical-based measure of cluster fit and characteristics of the resulting Hospital Groups. Using recent hospital utilization data, the clustering methodology identified 33 Hospital Groups in Michigan. Despite being developed within the politically charged climate of Certificate of Need regulation, we have provided an objective, replicable, and sustainable methodology to create Hospital Groups. Because the methodology is built upon theoretically sound principles of clustering analysis and health care service utilization, it is highly transferable across applications and suitable for grouping facilities or areal units.

Anemia in the elderly is often related to a higher prevalence of chronic diseases such as chronic kidney failure, arthritis, and malignancy. Erythropoiesis-stimulating agents (ESAs) have been used for years to effectively treat anemia and when used appropriately can substantially improve the health status and quality of life of older adults. Following the 2008 recession in Greece, the government introduced ESA price control restrictions, but no prescribing restrictions, in an effort to reduce drug expenditure. ESA prescribing patterns and treatment costs were analyzed to determine inappropriate or appropriate use of these agents and related health care resources in Greece. A retrospective register-based drug utilization study was carried out using data from prescriptions dispensed at the public pharmacy of the largest social insurance fund (IKA-ETAM), for patients receiving ESAs over a six-month period. For each patient, demographic data, ESA dosage regimen, treatment indication and cost, prescriber specialty, and prescription origin were recorded. A total of 14,387 prescriptions from 6,074 patients (median age 74 years) were reviewed. A substantial number of patients (13.5%) were treated for off-label indications, for which the average cost per patient per indication was higher. ESA dosage/frequency of administration varied but was in accordance with recommendations. The percentage of patients who received innovator and biosimilar erythropoietin (EPO) was 88% and 12%, respectively. For the optimization of ESA utilization and the reduction of treatment costs, strict ESA prescription monitoring, development of registries, and criteria for off-label indications and biosimilar use in naive patients under the umbrella of risk-sharing agreements should be proposed.

The purpose of this article is disclose services utilization patterns among the Catalan population with particular emphasis on primary care, specialised care, hospital care and emergency care. A number of logistic regression models were used to explain the utilization of the various types of services. Variables in the analysis included self-perceived need, lifestyles, and sociodemographic variables. Separate analyses were performed for male, female, adults, and children as well as for the general population. Women use all types of services more often than men. Children and people over 64 are more frequent users of primary care. Primary care is also associated to lower socioeconomic conditions. Young adults and the migrant population in general are found to be under users of services, except of emergency care services. The use of specialised care is associated to the better-off, to those with university level education attainment, individual private insurance, and those living in the city of Barcelona. Hospital care is largely associated to need variables. The use of health services is explained by self-perceived need as well as by demographic, socioeconomic and geographical factors.

Changes in nailfold capillaroscopy in systemic sclerosis patients could be related to the disease severity. The aim of this study was to investigate whether patients with "late" scleroderma (SD) pattern have more organ involvement than patients with "early/active" SD pattern. Forty-six Argentinian patients (44 women and 2 men), with a diagnosis of systemic sclerosis, were distributed in two groups based on the presence of late and early/active patterns. Organ involvement was assessed as follows: pulmonary function by chest radiography, high-resolution chest tomography (HRCT), lung volume tests, and diffusing capacity for carbon monoxide (DLCO); esophageal involvement by manometry; and pulmonary arterial hypertension (PAH) by Doppler echocardiography and six-minute walk test. Honeycombing of the lungs evaluated by HRCT was more frequently present in patients with late pattern compared with early/active patients (p = 0.01). We also found statistically significant differences in lung volume tests (p = 0.03) and DLCO (p = 0.02) between the two SD pattern groups. Esophageal manometry showed a significantly higher frequency of motility disorders in the group with late pattern (p = 0.0024). In this study, patients with late pattern had higher frequency of pulmonary and esophageal involvement compared with patients with early/active pattern.

We reviewed the nuclear medicine files of all patients enrolled in the sickle cell disease clinic who had had scans performed within the previous 5 years. We specifically looked for patterns of tracer uptake in these scans that would correlate with the severe anemia and consequent bone marrow hyperactivity of sickle cell patients. Thirty-three patients were included (21 men and 12 women) with a mean age of 26.8 years (range 17-48 years). The appearance of each of these patients' most recent scans was examined in the areas of the distal femurs, the proximal tibias and the distal tibias; a distinct triangular shaped pattern of increased activity was identified in these areas in a majority of patients. Thirty-three patients without sickle cell disease served as age-matched controls. This pattern was seen in 65.1% (95 out of 146 images) of the sickle cell patients' delayed images and 80.4% (82 out of 102 images) of their blood pool images. In contrast, the control patients demonstrated the triangular pattern in none of their blood pool studies (0%) and only 10.9% of their delayed bone images (P<0.001). The mean age of sickle cell patients with this pattern is 25.6 years which was significantly lower than that of those without this pattern (mean=37.5 years, P<0.05). Given the high prevalence of this unique scintigraphic pattern in a group of patients with known accelerated bone marrow function, these findings may be scintigraphic evidence of bone marrow expansion. The patient's age appears to be an important factor in visualization of this pattern. (orig.)

To investigate the patterns of care and outcomes in patients with craniopharyngioma in the National Cancer Data Base (NCDB). This study included 697 patients (166 pediatric and 531 adult cases) treated for craniopharyngioma between 2004 and 2012 in the NCDB. Adjuvant radiotherapy (RT) was defined if within 6 months of surgery. Limited surgery (LS) was defined as biopsy or subtotal resection. Proportional-hazards models were used to evaluate associations between covariates and overall survival (OS). A time-dependent analysis of RT was performed to account for early deaths after surgery. Median follow-up was 46 months. Overall, 21% of patients received adjuvant RT. Of patients with known surgical extent (n = 195), 71% had LS. Utilization of adjuvant RT increased from 18% in 2004-2007 to 24% in 2008-2012. Patterns of care regarding adjuvant RT or LS were not significantly different between adult and pediatric patients. Tumor size, low comorbidity, and LS were associated with increased utilization of adjuvant RT. The 5-year OS among patients treated with LS, LS+RT, and gross total resection were 75, 85, and 82% (p = 0.02). On multivariate analysis of the 195 patients with known surgical extent, LS+RT was associated with improved OS compared to LS (HR 0.22, 95% CI 0.05-0.99, p = 0.04), but was not significant when early deaths (craniopharyngiomas. Immortal-time bias may confound assessment of OS for adjuvant RT. Prospective studies comparing adjuvant RT versus observation after LS are warranted.

Drugs used in the palliative care unit for managing symptoms are major contributors toward the expenditure occurring in palliative care. This study was conducted to understand the prescription pattern of analgesic drugs in the patients who are receiving palliative care in a teaching hospital in India by a retrospective study of case records. Case record based, retrospective, descriptive study was conducted at the Pain and Palliative Care Department of St. John's Medical College Hospital, Bengaluru. Case record files of all patients referred to Pain and Palliative Care Department for the treatment of pain in the year of 2012 were studied. Patients' age, gender, diagnoses, numerical pain rating scale (0-10), drugs prescribed, dosage, frequency, route of administration were recorded. The difference in drug utilization between the genders was done using Chi-square test. Data were collected from 502 patients of which 280 (56%) were males and 222 (44%) were females. Twelve percent of patients had mild pain (1-3), 34% had moderate pain (4-6), and 54% had severe pain (7-10). The most commonly used analgesic drugs were opioids (47%), followed by nonsteroidal anti-inflammatory drugs (36%). The opioids used were tramadol (56%), and morphine (38%). Ninety percent of patients with numerical pain scale more than 6 received morphine. There was no difference in analgesic drug utilization with regards to gender. Prescription pattern differed depending on the severity of pain. Opioids were the most commonly used drugs for pain management. The study shows that prescription pattern in palliative care unit of this hospital was in accordance with WHO pain management guidelines. The study showed the current trend in prescription of analgesic drugs in the teaching hospital where the study was conducted.

Terminal intensive care unit (ICU) stays represent an important target to increase value of care. To characterize patterns of daily costs of ICU care at the end of life and, based on these patterns, examine the role for palliative care interventions in enhancing value. Secondary analysis of an intervention study to improve quality of care for critically ill patients. 572 patients who died in the ICU between 2003 and 2005 at a Level-1 trauma center. Data were linked with hospital financial records. Costs were categorized into direct fixed, direct variable, and indirect costs. Patterns of daily costs were explored using generalized estimating equations stratified by length of stay, cause of death, ICU type, and insurance status. Estimates from the literature of effects of palliative care interventions on ICU utilization were used to simulate potential cost savings under different time horizons and reimbursement models. Mean cost for a terminal ICU stay was 39.3K ± 45.1K. Direct fixed costs represented 45% of total hospital costs, direct variable costs 20%, and indirect costs 34%. Day of admission was most expensive (mean 9.6K ± 7.6K); average cost for subsequent days was 4.8K ± 3.4K and stable over time and patient characteristics. Terminal ICU stays display consistent cost patterns across patient characteristics. Savings can be realized with interventions that align care with patient preferences, helping to prevent unwanted ICU utilization at end of life. Cost modeling suggests that implications vary depending on time horizon and reimbursement models.

Comorbid mental disorders in patients with coronary artery disease (CAD) are common and associated with adverse somatic outcomes. However, data on utilization rates of mental health care and treatment efficiency are scarce and inconsistent, which we tried to remedy with the present preliminary study on Northern German CAD patients. A total of 514 German CAD patients, as diagnosed by cardiac catheterization, were assessed using the Mini International Neuropsychiatric Interview and the Global Assessment of Functioning (GAF) scale. Global utilization of mental health care since onset of CAD was 21.0%. Depressive disorders, younger age, and lower GAF at onset of CAD were associated with higher utilization rates, while anxiety disorders and gender were not. Lower GAF at onset of CAD, female gender, and psychotherapy was positively associated with higher gains in GAF, while younger age and anxiety disorders were negatively associated. The majority of CAD patients with comorbid depression reported to have received mental health treatment and seemed to have benefited from it. However, we found preliminary evidence of insufficiencies in the diagnosis and treatment of anxiety disorders in CAD patients. Further studies, preferably prospective and with representative samples, are needed to corroborate or falsify these findings and explore possible further mediators of health-care utilization by CAD patients such as race, ethnicity, and socioeconomic status.

Full Text Available Purpose: Discordance with the guidelines and underutilization of pharmacotherapy for secondary prevention frequently exists in clinical practice. Aim of our study was to assess the prescription routine and drug utilization patterns for antiplatelets and peroral anticoagulants in tertiary medical center specialized for cardiovascular rehabilitation. Methods: study included 96 consecutive patients scheduled for cardiovascular rehabilitation in period 1-6 months after the acute treatment for ischemic 87(80.2% and valvular heart disease 18(19.8%. Patients were divided according to etiology of heart disease and type of acute cardiovascular treatments (conservative, percutaneous coronary interventions (PCI and surgery. Results: Dual antiplatelet therapy was the most commonly applied regimen in 84(87.5% of conservatively treated myocardial infarctions, 47(61.9% of percutaneous coronary interventions (PCI and 13(58.9% of surgically treated group (p>0.05. Among studied group of patients significant differences in utilization were found for warfarin, or combinations of antiplatelets with warfarin(p0.05. All four of patients that received triple therapy (4.17% were from surgical group. Underutilization of antiplatelets in ischemic heart disease was at 11(14.3% what was congruent with the developed industrial nations. Conclusions: Acute cardiovascular treatment type, but not heart disease etiology, had significant influence on subsequent prescription routine. Decreased use of pharmacological agents for secondary prevention in surgical patients was revealed. Drug utilization analyzes can offer improvement in optimizing medical treatments, quality of care and decrease unnecessary polypragmasia, as well as improve economical efficiency of medical management.

2014-01-01

Background Effective integration of visual information is necessary to utilize abstract thinking, but patients with schizophrenia have slow eye movement and usually explore limited visual information. This study examines the relationship between abstract thinking ability and the pattern of eye gaze in patients with schizophrenia using a novel theme identification task. Methods Twenty patients with schizophrenia and 22 healthy controls completed the theme identification task, in which subjects selected which word, out of a set of provided words, best described the theme of a picture. Eye gaze while performing the task was recorded by the eye tracker. Results Patients exhibited a significantly lower correct rate for theme identification and lesser fixation and saccade counts than controls. The correct rate was significantly correlated with the fixation count in patients, but not in controls. Conclusions Patients with schizophrenia showed impaired abstract thinking and decreased quality of gaze, which were positively associated with each other. Theme identification and eye gaze appear to be useful as tools for the objective measurement of abstract thinking in patients with schizophrenia. PMID:24739356

Hiller, Wolfgang; Fichter, Manfred M

2004-04-01

Patients with somatoform disorders (SFD) are likely to overutilize healthcare services. This study investigates (a) whether extraordinarily high medical costs can be predicted from patient characteristics or psychopathology, and (b) whether high-utilizing patients respond differently to cognitive-behavioral treatment. We compared 42 SFD high utilizers with 53 SFD average utilizers and 29 patients suffering from other than SFD mental disorders. High utilization was defined by healthcare expenditures of > or = 2500 euros during the past 2 years. Costs were computed from medical and billing records of health insurance companies. Somatization distress, hypochondriasis, depression, dysfunctional cognitions related to bodily symptoms, general psychopathology, personality profiles, and psychosocial disabilities were assessed before treatment. High utilizers had higher levels of self- and observer-rated illness behavior, self-perceived bodily weakness, and psychosocial disabilities. Although they did not report more somatization symptoms, their subjective symptom distress was higher. There were no differences between high and average utilizers concerning general psychopathology, DSM-IV comorbidity, and personality profiles. Treatment improvements were similar. High- and average-utilizing somatizers represent distinguishable subgroups. The results emphasize the importance of mechanisms specifically related to SFD and may enhance the early detection of patients who are likely to develop overutilization. Copyright 2004 Elsevier Inc.

Purpose: Studies describing the use of the Internet by radiation oncology patients are lacking. This multi-institutional study of cancer patients presenting to academic (AC), community (CO) and veterans (VA) radiation oncology centers was designed to analyze the use of the Internet, predictive factors for utilization, and barriers to access to the Internet. Materials and Methods: A questionnaire evaluating the use of the Internet was administered to 921 consecutive patients presenting to radiation oncology departments at AC, CO and VA Medical Centers. The study included 436 AC patients (47%), 284 CO patients (31%), and 201 VA patients (22%). A computer was available at home to 427 patients (46%) and 337 patients (37%) had Email access. The mean age of the patient population was 64 years (range=14-93). Males represented 70% of the patient population. The most common diagnoses included prostate cancer (33%), breast cancer (13%), and lung cancer (11%). Results: Overall, 265/921 patients (29%) were using the Internet to find cancer related information. The Internet was used by 42% of AC patients, 25% of CO patients and only 5% of VA patients (p<.0001). A computer was available at home in 62% AC vs. 45% CO vs. 12% VA patients (p<.0001). Patients < 60 years were much more likely to use the Internet than older patients (p<.0001). Most of the Internet users considered the information either very reliable (22%) or somewhat reliable (70%). Most patients were looking for information regarding treatment of their cancer (90%), management of side effects of treatment (74%), alternative/complementary treatments (65%) and clinical trials (51%). Unconventional medical therapies were purchased over the Internet by 12% of computer users. Products or services for the treatment or management of cancer were purchased online by 12% of Internet users. Conclusion: A significant number of cancer patients seen in radiation oncology departments at academic and community medical centers

Ito, H; Fujii, K; Sasaki, Y

1998-01-01

The purpose of this paper is to clarify some patterns of utilization of an external employee assistance program (EAP) we have conducted for other public and private facilities in the Tokyo Kenbikyoin Foundation between April, 1986 and December, 1996. The subjects were 26 men and 12 women in 7 facilities under the following conditions: (1) Employees who have already had their own psychiatrists at the first interview of the external EAP; (2) Facilities utilize the EAP for two or more employees who met the first criterion. As a result, utilization patterns differed depending on medical staff's attitude toward the external EAP. There was a significant difference according to sex. The rate for men was 54% in worksites where medical staff understood this external program (worksite A1) and 93% in worksites where they did not (worksite A2-3, B). As to expectations for the program, there were more consultations for organizational measurements (63%) in worksite A1, while less organizational matters (27%) and more personal complains about their psychiatrists in the worksite A2-3, and B. These results suggest that the involvement of medical staff is the key to utilizing the external EAP effectively.

To perform a cost-utility analysis on asthmatic patients on beclomethasone/formoterol fixed combination in Primary Health Care. Material and methods Non-probability sampling was used to select a group of asthmatic patients with moderate/severe persistent severity (GEMA 2009), treated with beclomethasone/formoterol fixed combination, over 18 years, had given their informed consent. The study observation period was 6 months. The variables studied were: age, sex, duration of disease, health resources used, analysis of health related quality of life by EQ-5D and SF-36, and the specific Asthma Quality of Life Questionnaire. For the qualitative variables, the frequency and percentages were calculated, and for the quantitative variables, the mean, SD and 95% CI. Chi-square, Student t-test and ANOVA were used for statistical inference. Comparisons were made with a statistical significance of 0.05. Of the 64 patients that completed the study, 59.4% were female. The mean age was 49 years, and mean disease duration was 93 months. For asthma control, 53% of patients had a prescription pattern of one/12h. All health related quality of life scales were modified with respect to the baseline and the differences were statistically significant. Our patients had a better health related quality of life than Spanish asthma cohort. The incremental cost utility beclomethasone/formoterol versus usual treatment option was € 6,256/QALY.

European clinical guidelines recommend a low-density lipoprotein cholesterol (LDL-C) goal of C goal attainment among atherosclerotic CV disease (ASCVD) patients with various utilization patterns of moderate- or high-intensity statins in routine care. This retrospective cohort study used electronic medical records data from the QuintilesIMS® Disease Analyzer (> 2 million individuals annually) to identify ASCVD (coronary atherosclerosis, stable/unstable angina, myocardial infarction, ischemic stroke, transient ischemic attack, aneurysm, peripheral artery disease) patients on moderate-/high-intensity statin in Germany. Proportion of patients with LDL-C C value for each patient (index) in 2012, 2013, and 2014, while on statin. Treatment patterns were assessed for patients with at least 1 year of post-index follow-up. Results were stratified by year and treatment pattern [no change, switch, dose up-/down-titration, discontinuation (≥ 90 day gap)]. In > 14,000 patients assessed in each year (mean age 71 years, 35% female, 8-12% taking high-intensity statins), approximately 80% had LDL-C ≥ 70 mg/dL. Treatment patterns were assessed for most (88-93%) patients. Approximately 79-81% of patients made no change to statin regimens, 1% switched statins, 14-16% discontinued; 1% of moderate-intensity patients up-titrated, and 3% of all patients down-titrated. LDL-C goal attainment in these treatment pattern groups was 20, 16-24, 17, 11-14, and 17-19%, respectively. Majority of ASCVD patients had LDL-C ≥ 70 mg/dL while on moderate-/high-intensity statins. Despite low LDL-C goal attainment, few patients changed their treatment regimens.

Borderline personality disorder (BPD) is characterized by a pervasive pattern of instability and impulsivity. Several North American prospective studies support the high level of mental health care utilization in this population. There is little data in other systems of health organization, such as France. Furthermore, little is known on the variables associated with the mental health service utilization among BPD patients. The main objective was to compare the utilization of mental health care among BPD patients, to the general population and patients with another personality disorder (PD) and to describe the demographic and clinical factors associated with the group of patients who use the most health care. A multi-center (5 public and private centers), epidemiological study. Data were collected prospectively (database of an insurance fund covering 80% of the population) and viewed, retrospectively. We used the data collected during the five years previously to the inclusion. Inclusion criteria were age (18-60 years) and membership in the health insurance fund targeted. Patients on legal protection, forced hospitalization, with a chronic psychotic disorder, manic, mental retardation, or not reading French were excluded. First, four groups were composed: BPD, other PD, control groups for PD and other PD. The first two groups were recruited from a screening of inpatients including a self-administered questionnaire (Personality Disorder Questionnaire 4+). Assessment by a psychologist including the Structured Interview for DSM-IV Personality Disorders (SIDP-IV) was given straight to those who had a score above 28. This questionnaire allowed us to distinguish one group of subjects with BPD and a group with other PD (without BPD). Clinical evaluation included Axis I (MINI), Axis II (SIDP-IV), psychopathological features (YSQ-I, DSQ-40), demographic variables and therapeutic alliance (Haq-II). Matched controls (age, sex) composed the 3rd and 4th group (BPD control and

Real-world evidence on glucagon-like peptide-1 receptor agonist (GLP-1 RAs) usage is emerging in different European countries but is lacking in Italy. This retrospective cohort study aimed to describe the real-world drug utilization patterns in patients initiating GLP-1 RAs for treating T2DM in Italy. Adults aged ≥ 20 years and with ≥ 1 oral antidiabetic drug (alone or in combination with insulin) other than GLP-1 RAs in the 6 months prior to initiating exenatide twice daily (exBID), exenatide once weekly (exQW), dulaglutide once weekly (DULA), liraglutide once daily (LIRA) or lixisenatide once daily (LIXI) between March and July 2016 were retrospectively identified in the Italian IMS LifeLink™ longitudinal prescriptions database (retail pharmacy data). Patients with ≥ 6-month follow-up (defined as evidence of any prescription activity) were included. Proportions of patients who remained persistent (continued treatment until discontinuation/switch) in the first 6 months and of those who discontinued or switched to a different GLP-1 RA over the entire follow-up were recorded. For each treatment, the average daily/weekly dosage (ADD/AWD) while persistent during the available follow-up was calculated. We identified 7319 patients: 92 exBID, 970 exQW, 3368 DULA, 2573 LIRA and 316 LIXI. Across treatments, 89% patients were ≥ 50 years old, 54% were males, and the median follow-up duration ranged between 8.1 and 8.7 months. At 6 months, 35% exBID, 47% exQW, 62% DULA, 50% LIRA and 40% LIXI patients remained persistent. Over the entire follow-up, median persistence days varied from 73 (exBID) to > 300 days (DULA). The mean ± SD ADD/AWD was exBID: 17.7 ± 2.1 µg/day; exQW: 2.1 ± 0.1 mg/week; DULA: 1.5 ± 0.2 mg/week; LIRA: 1.5 ± 0.2 mg/day; LIXI: 21.0 ± 5.5 µg/day. This real-world analysis suggests differences exist in persistence between patients treated with various GLP-1 RAs. Among the investigated

To make clear the characteristics of cerebral glucose utilization in dementia, PET studies with 18F-FDG were carried out. Taking the pattern of 18F-FDG utilization, dementia can be subdivided into two types. One type shows a simultaneous and symmetrical reduction glucose utilization in the posterior part of neocortex covering the temporal, parietal and occipital association cortices. This is referred to as type I. Although this type constitutes only about 1/5 of all dementia patients, it is considered the fundamental type of dementia. Aside from this, there is type wherein a simultaneous and symmetrical reduction in glucose utilization of the neocortex. This is type II. It constitutes about 4/5 of all dementia patients which is far more type I. There are no essential difference in the characteristics of cerebral glucose utilization in AD and MID. However, with regards the mean, AD is lower than MID. Various organic defect in neocortex do not correlate with the global reduction in glucose utilization in dementia patients. These results suggest that the reduction in glucose utilization in dementia may be functional disorder. (author).

Quantifying the Effect of Fast Charger Deployments on Electric Vehicle Utility and Travel Patterns via Advanced Simulation: Preprint

Energy Technology Data Exchange (ETDEWEB)

Wood, E.; Neubauer, J.; Burton, E.

2015-02-01

The disparate characteristics between conventional (CVs) and battery electric vehicles (BEVs) in terms of driving range, refill/recharge time, and availability of refuel/recharge infrastructure inherently limit the relative utility of BEVs when benchmarked against traditional driver travel patterns. However, given a high penetration of high-power public charging combined with driver tolerance for rerouting travel to facilitate charging on long-distance trips, the difference in utility between CVs and BEVs could be marginalized. We quantify the relationships between BEV utility, the deployment of fast chargers, and driver tolerance for rerouting travel and extending travel durations by simulating BEVs operated over real-world travel patterns using the National Renewable Energy Laboratory's Battery Lifetime Analysis and Simulation Tool for Vehicles (BLAST-V). With support from the U.S. Department of Energy's Vehicle Technologies Office, BLAST-V has been developed to include algorithms for estimating the available range of BEVs prior to the start of trips, for rerouting baseline travel to utilize public charging infrastructure when necessary, and for making driver travel decisions for those trips in the presence of available public charging infrastructure, all while conducting advanced vehicle simulations that account for battery electrical, thermal, and degradation response. Results from BLAST-V simulations on vehicle utility, frequency of inserted stops, duration of charging events, and additional time and distance necessary for rerouting travel are presented to illustrate how BEV utility and travel patterns can be affected by various fast charge deployments.

Full Text Available Objective To evaluate the utilization profile of antiepileptic drugs in a population of adult patients with refractory epilepsy attending a tertiary center. Method Descriptive analyses of data were obtained from the medical records of 112 patients. Other clinical and demographic characteristics were also registered. Results Polytherapies with ≥3 antiepileptic drugs were prescribed to 60.7% of patients. Of the old agents, carbamazepine and clobazam were the most commonly prescribed (72.3% and 58.9% of the patients, respectively. Among the new agents, lamotrigine was the most commonly prescribed (36.6% of the patients. At least one old agent was identified in 103 out of the 104 polytherapies, while at least one new agent was prescribed to 70.5% of the population. The most prevalent combination was carbamazepine + clobazam + lamotrigine. The mean AED load found was 3.3 (range 0.4–7.7. Conclusion The pattern of use of individual drugs, although consistent with current treatment guidelines, is strongly influenced by the public health system.

The presence of male pattern baldness poses a significant challenge when attempting to optimize treatment of the upper third of the face. The purpose of this study is to demonstrate and discuss results of the endoscopic forehead lift in patients with male pattern baldness. This was a retrospective case series done in an academic medical center. Eleven patients with male pattern baldness (Norwood class IV-VII) underwent endoscopic forehead lift for forehead creases and brow ptosis. All patients achieved smoothing of the forehead and elevation of the brow with no scalp anesthesia at 1 month postoperatively. All patients were pleased with the healing of their incisions in midline, paramedian, and temporal regions. Alloplastic fixation devices used were visible postoperatively in 2 patients initially. The endoscopic forehead lift is a suitable approach for treating the upper third of the face in the presence of male pattern baldness. The use of alloplastic fixation devices may be used in this patient population, but other fixation methods should be considered. Copyright © 2012 Elsevier Inc. All rights reserved.

Full Text Available Abstract Background There are limited findings about dietary patterns and food preferences among patients suffering from schizophrenia. The main objective of this study was therefore to compare the nutritional pattern of schizophrenia patients with that of matched healthy subjects. Methods The dietary pattern of 30 hospitalized 16–67 years old schizophrenic patients (11 female was compared with that of 30 healthy age and sex matched individuals as control group. Subjects' anthropometric measurements including weight, height and body mass index (BMI, semi-quantitative food frequency (FFQ, medical and food history questionnaires were also collected and FFQs were then scored using Food Guide Pyramid to obtain the dietary scores. Percent body fat (%BF was measured using bioelectrical impedance analysis (BIA method. Results Female patients had more %BF and lower dietary pattern scores than that of their controls (32 ± 3.6 vs 27.7 ± 4.6 percent and 43.2 ± 11.9 vs 54.5 ± 10.7 points; respectively, p Conclusion Schizophrenia patients have poor nutritional patterns. In particular, female patients have more percent body fat and lower dietary pattern scores compared with their healthy controls. All patients used to consume more fats and sweet drinks frequently. The findings of this study suggest that schizophrenia patients need specific medical nutrition therapies through limiting dietary fats and sugars intakes and weight control. Whether obesity is the consequence of disease, dietary preference or medications used remains to be cleared.

To evaluate the patterns of cerebral cortical distribution of (11)C-PIB in patients with mild cognitive impairment (MCI). The study included 69 patients (37 male, age range 42-79 years) with MCI, sub-classified as 53 with amnestic-MCI (A-MCI), and 16 with non-amnestic-MCI (NA-MCI). Patients underwent (11)C-PIB PET/CT scan 60min after intravenous injection of the radiotracer. A visual analysis of the images was performed by 2 experienced physicians. (11)C-PIB-positive studies were considered when gray matter uptake was equal to or greater than white matter. According to the regions involved, (11)C-PIB-positive studies were classified into A-pattern (predominant retention in frontal, anterior cingulate, lateral temporal, and basal ganglia) and B-pattern (generalized retention). Thirty-nine of the 69 (56%) patients with MCI showed (11)C-PIB retention. Of the 53 A-MCI patients, 36 (68%) showed (11)C-PIB retention. Eleven out of 36 (30%) positive scans in A-MCI patients showed A-pattern, and 25 out of 36 (70%) patients had a B-pattern. Positive (11)C-PIB was observed in 3 out of 16 (19%) patients with NA-MCI. Regional distribution in these 3 patients showed A-pattern in 1, and B-pattern in 2 patients. Cortical retention of (11)C-PIB was more frequent in A-MCI than in NA-MCI patients, and also B-pattern than A-pattern in the (11)C-PIB positive group. The recognition of (11)C-PIB distribution patterns allows MCI patients to be classified, and the A-pattern may offer a therapeutic window for potential future treatments.

Control rod pattern exchange in a BWR/6 utilizing gang mode withdrawal

International Nuclear Information System (INIS)

Auvil, A.B. Jr.; Aldemir, T.; Hajek, B.K.

1986-01-01

The use of checkerboard pattern of alternating inserted and fully withdrawn control rods and the uneven void distribution in boiling water reactor (BWR) cores can cause large burnup gradients even after a short time of operation. To compensate for these effects, power has to be reshaped periodically (typically every two full-power months) by individually manipulating the control rods. During this manipulation process (called the control rod pattern exchange), the core power is reduced to 60% of nominal power by means of flow reduction to limit power swings to tolerable levels and to ensure that fuel thermal limits are not exceeded. A control rod pattern exchange by individual rod manipulation typically takes 4 to 8 h and represents a large cost burden to the utility in terms of reduced system output. The latest generation of BWRs, the BWR/6, possesses the capability to simultaneously move up to four symmetrically located control rods. The rods corresponding to a given gang may have rotational symmetry, mirror symmetry, or a combination of the two. This paper presents a pattern exchange procedure that exploits the capability of gang mode rod withdrawal to reduce the pattern exchange execution time and radial power distribution asymmetry associated with individual rod manipulation. The working model used in the study is the Perry Nuclear Power Plant Unit 1, located in Perry, Ohio, and owned by the Cleveland Electric Illuminating Company

Clinical Approach to the Standardization of Oriental Medical Diagnostic Pattern Identification in Stroke Patients

2011-01-01

Full Text Available In Korea, many stroke patients receive oriental medical care, in which pattern-identification plays a major role. Pattern-identification is Oriental Medicine's unique diagnostic system. This study attempted to standardize oriental medical pattern-identification for stroke patients. This was a community-based multicenter study that enrolled stroke patients within 30 days after their ictus. We assessed the patients' general characteristics and symptoms related to pattern-identification. Each patient's pattern was determined when two doctors had the same opinion. To determine which variables affect the pattern-identification, binary logistic regression analysis was used with the backward method. A total of 806 stroke patients were enrolled. Among 480 patients who were identified as having a certain pattern, 100 patients exhibited the Fire Heat Pattern, 210 patients the Phlegm Dampness Pattern, nine patients the Blood Stasis Pattern, 110 patients the Qi Deficiency Pattern, and 51 patients the Yin Deficiency Pattern. After the regression analysis, the predictive logistic equations for the Fire Heat, Phlegm Dampness, Qi Deficiency, and Yin Deficiency patterns were determined. The Blood Stasis Pattern was omitted because the sample size was too small. Predictive logistic equations were suggested for four of the patterns. These criteria would be useful in determining each stroke patient's pattern in clinics. However, further studies with large samples are necessary to validate and confirm these criteria.

Full Text Available A study was conducted in Krishnagiri district of Tamil Nadu state to understand the utilization pattern of extension tools and methods by the agricultural extension agents. As ICT revolution is slowly conquering the rural sector, it becomes imperative that the agricultural extension agents transform themselves to the changing times and develop competencies in utilizing these ICTs.  The study explored the usage of various extension tools and methods by the change agents and the constraints faced in utilizing them. The findings revealed that the extension functionaries frequently used the individual contact methods viz., telephone, office calls and farm and home visits in the process of transfer of technology. Least efforts were shown in sending SMS based communication. Meetings were the common and frequently adopted group contact method. Demonstrations, farmer field school, farmer’s interest groups, field trips and farmer training programmes were moderately adopted. Posters, leaflets and pre-season campaigns were the widely adopted mass contact methods. They possess least skill in utilizing farm magazines, presenting television and radio programmes, which are among the most popular and most efficient mass contact methods. The extension functionaries need to be trained adequately on the wider use of electronic communication methods like e mails, and SMS in the local language. Efforts should be taken up to sensitize the importance and train the extension agents in the usage of different group and mass contact methods.

Objective. To assess the utility of CT in the evaluation of pulmonary tuberculosis in patients without AIDS. Patients and methods. Thin-section CT scans for suspicion of pulmonary tuberculosis were obtained from 226 patients. A total of 38 patients were excluded; the reasons were unavailability of final results (n=18), patient unavailability for follow-up (n=13), and coexistence of tuberculosis and aspergilloma (n=7). The results from 188 patients were used for this study. After assessing the patterns of parenchymal lesion, involved segments, and presence of cavity, bronchiectases, and bronchogenic spread of the lesion with CT, tentative diagnosis and disease activity were recorded. Results. With CT, 133 of 146 patients (91%) with tuberculosis were correctly diagnosed as having pulmonary tuberculosis whereas 32 of 42 patients (76%) without tuberculosis were correctly excluded. CT diagnosis of lung cancer (n=8), bacterial pneumonia (n=2), pulmonary metastasis (n=1), chronic hypersensitivity pneumonia (n=1) and diffuse pan-bronchiolitis (n=1) turned out to be tuberculosis. Conversely CT diagnoses of tuberculosis appeared pathologically as lung cancer (n=5), bacterial pneumonia 71/89, 80%) and inactive state (51/57, 89%) of disease respectively could be correctly differentiated by CT. Conclusion. CT can be helpful in the diagnosis of pulmonary tuberculosis in most cases. On the basis of CT findings, distinction of active from inactive disease can be made in most cases. (authors)

Health-care costs following acute hospital care have been identified as a major contributor to regional variation in Medicare spending. This study investigated the associations of preoperative physical therapy and post-acute care resource use and its effect on the total cost of care during primary hip or knee arthroplasty. Historical claims data were analyzed using the Centers for Medicare & Medicaid Services Limited Data Set files for Diagnosis Related Group 470. Analysis included descriptive statistics of patient demographic characteristics, comorbidities, procedures, and post-acute care utilization patterns, which included skilled nursing facility, home health agency, or inpatient rehabilitation facility, during the ninety-day period after a surgical hospitalization. To evaluate the associations, we used bivariate and multivariate techniques focused on post-acute care use and total episode-of-care costs. The Limited Data Set provided 4733 index hip or knee replacement cases for analysis within the thirty-nine-county Medicare hospital referral cluster. Post-acute care utilization was a significant variable in the total cost of care for the ninety-day episode. Overall, 77.0% of patients used post-acute care services after surgery. Post-acute care utilization decreased if preoperative physical therapy was used, with only 54.2% of the preoperative physical therapy cohort using post-acute care services. However, 79.7% of the non-preoperative physical therapy cohort used post-acute care services. After adjusting for demographic characteristics and comorbidities, the use of preoperative physical therapy was associated with a significant 29% reduction in post-acute care use, including an $871 reduction of episode payment driven largely by a reduction in payments for skilled nursing facility ($1093), home health agency ($527), and inpatient rehabilitation ($172). The use of preoperative physical therapy was associated with a 29% decrease in the use of any post-acute care

Obesity among patients with schizophrenia is a growing concern because being overweight is widely regarded as a major risk factor for cardiovascular disease and premature death. Dietary patterns have been suggested as one modifiable factor that may play a role in development of obesity. The objective of this study was to examine the association between dietary patterns and obesity among patients with schizophrenia in Japan. We recruited patients (n = 338) aged 44.0 ± 13.2 (mean ± SD) years with a DSM-IV diagnosis of schizophrenia who were admitted to four psychiatric hospitals using a cross-sectional design. Diet was assessed with a validated brief-type self-administered diet history questionnaire (BDHQ). Dietary patterns from 52 predefined food groups were extracted by principal component analysis. A total of 61 subjects (18.0%) were classified as obese. Three dietary patterns were identified: the healthy dietary pattern, the processed food dietary pattern, and the alcohol and accompanying dietary patterns. After adjusting for age and gender, patients within the high tertile of each healthy dietary pattern (OR = 0.29, 95% CI = 0.13 to 0.62) and processed food dietary pattern (OR = 0.44, 95% CI = 0.22 to 0.89) had a significantly lower risk for obesity compared with low tertile of dietary pattern. Our findings suggest that dietary patterns, including higher intake of protein, fat, n-3 polyunsaturated fatty acids, n-6 polyunsaturated fatty acids, and vitamins, may be related to a decreased prevalence of obesity within patients with schizophrenia. Future longitudinal research exploring dietary patterns and obesity among patients with schizophrenia is warranted.

Purpose: The objective of this study was to evaluate treatment patterns, budget impact, and health care resource utilization (HRU associated with D-ER use in a real-world setting. Methods: A retrospective claims database analysis was conducted using the HealthCore Integrated Research DatabaseSM. Adherence (measured by medication possession ratio, or [MPR] and persistence (measured by days between initial D-ER claim and discontinuation or end of follow-up were evaluated over 1-year follow-up. Budget impact was calculated as cost per member per month (PMPM over the available follow-up period. D-ER and control cohorts were propensity-score matched on baseline demographics, comorbidities, and MS-related resource utilization to compare walking-impairment-related HRU over follow-up. Results: Of the 2,138 MS patients identified, 1,200 were not treated with D-ER (control and 938 were treated with D-ER. Patients were aged 51 years on average and 74% female. Approximately 82.6% of D-ER patients were adherent (MPR >80%. The estimated budget impact range of D-ER was $0.014–$0.026 PMPM. Propensity-score-matched D-ER and controls yielded 479 patients in each cohort. Postmatching comparison showed that the D-ER cohort was associated with fewer physician (21.5% vs 62.4%, P<0.0001 and other outpatient visits (22.8% vs 51.4%, P<0.0001 over the 12-month follow-up.

Somatization and hypochondriacal health anxiety are common sources of distress, impairment, and costly medical utilization in primary care practice. A range of interventions is needed to improve the care of these patients. To determine the effectiveness of two cognitive behavioral interventions for high-utilizing, somatizing patients, using the resources found in a routine care setting. Patients were randomly assigned to a two-step cognitive behavioral treatment program accompanied by a training seminar for their primary care physicians, or to relaxation training. Providers routinely working in these patients' primary care practices delivered the cognitive behavior therapy and relaxation training. A follow-up assessment was completed immediately prior to treatment and 6 and 12 months later. Eighty-nine medical outpatients with elevated levels of somatization, hypochondriacal health anxiety, and medical care utilization. Somatization and hypochondriasis, overall psychiatric distress, and role impairment were assessed with well-validated, self-report questionnaires. Outpatient visits and medical care costs before and after the intervention were obtained from the encounter claims database. At 6 month and 12 month follow-up, both intervention groups showed significant improvements in somatization (p somatization, hypochondriacal symptoms, overall psychiatric distress, and role function. They also reduced the ambulatory visits and costs of these high utilizing outpatients.

Nonretroperitoneal abdominal soft tissue sarcoma (NRA-STS) is a rare disease with limited data supporting its management. Our study aimed to reveal the utilization patterns of adjuvant therapy and its potential survival benefits using the National Cancer Data Base. The analysis included patients with resected high-grade NRA-STS. Chi-square analysis was used to evaluate distribution of patient and tumor-related factors within treatment groups. The Kaplan-Meier and Cox proportional hazards model were utilized to evaluate overall survival according to treatment approach. Multivariate analysis was used to determine the impact of these factors on patients' outcome. Matched propensity score analysis was implemented to control for imbalance of confounding variables. At median follow-up of 49 months, 5-year overall survival improved from 46% without adjuvant radiation therapy to 52% (P = 0.009) with radiotherapy delivery with a 30% reduction in hazard of death (95% confidence interval = 0.58-0.84). On multivariate analysis, age <50, tumor <8 cm, negative margins and radiotherapy delivery were significant predictors of improved survival. Chemotherapy was not associated with significant survival improvement (Hazard Ratios [HR]: 0.89, P = 0.28). Adjuvant radiotherapy was associated with improved survival in high-grade NRA-STS. Chemotherapy was not associated with a survival improvement; however, further studies are needed to refine treatment strategies. © 2017 John Wiley & Sons Australia, Ltd.

Assess changes in resource utilization, work and activity impairment, and health utility among OAB patients continuing to have urgency symptoms with tolterodine ER 4 mg and willing to try solifenacin 5/10 mg. This was an open-label, non-comparative, flexible-dosing, multicenter, 12-week study assessing the efficacy and safety of solifenacin 5/10 mg/day. Patients receiving tolterodine ER 4 mg/day for >/=4 weeks but continuing to experience residual urgency symptoms (>/=3 urgency episodes/24 h) were enrolled into the study. After a 14-day washout, patients began treatment with solifenacin 5 mg/day with dosing adjustments allowed at Weeks 4 and 8. Outcomes were assessed using the Work Productivity and Activity Impairment Questionnaire - Specific Health Problem (WPAI-SHP), Health Utilities Index (HUI), and a resource utilization questionnaire administered at Pre-Washout and Week 12. Patients (n=440) reported significantly fewer physician office visits (pwork time missed (p=0.0017), less impairment while working (pwork impairment (pwork productivity, activity participation, and reduced medical care use in OAB patients who continued to have urgency symptoms with tolterodine ER 4 mg/day and wished to switch to solifenacin 5/10 mg. This was an open-label, non-comparative study; therefore, further research is needed to confirm these results.

This study constitutes the first national longitudinal survey to address the relationship between workplace harassment and service utilization. We examine how patterns of sexual harassment and generalized workplace harassment are linked to utilization of mental health, health, legal, spiritual, and work-related services, and whether and how gender influences these relationships. Data derive from a random digit dial telephone survey with a continental US sample of employed adults. Eligibility criteria were being 18 years of age or over, and being employed at least 20 h per week at some time in the 12 months prior to the wave 1 survey. Out of 4116 households with eligible individuals, 2151 agreed to participate at wave 1. At wave 2, 1418 participated, thus, the overall response rate was 34.5%. We show that the patterning of workplace harassment over two time points (chronic, remission, onset, never harassed) is associated with the use of different types of services. Gender partially moderated the relationship between workplace harassment and services.

Because of the progressive increase in the number of immigrants and the uncertainty about the capacity of the Spanish health service to deal with the quantitative and qualitative increases in demand, the possibility of introducing changes to adapt our services to the new situation should be considered. Beginning with an analysis of the factors that influence health status and use of the health service, based on the National Health Survey (NHS), the European Statistics on Income and Living Conditions (EU-SILC) and the European Community Household Panel (ECHP), we compare the health profiles and patterns of medical resources utilization between the national and foreign populations. The pattern of demand for health services in the immigrant population corresponds basically to the needs of a young population in good health. According to NHS data, resource utilization among immigrants can even be lower than that among the national population. Assessing the link between health status and demand for healthcare from a dynamic point of view, by identifying variations in patterns of health and patterns of demand for healthcare, is important to identify imbalances in resources and to establish an appropriate hierarchy of preventive and treatment priorities.

It is important to conduct studies on the utilization of new antiepileptic drugs in order to improve their use. Our objective is to describe the use patterns of carbamazepine and oxcarbazepine. Observational, cross-sectional, national study with 58 investigators that included 185 pediatric patients with partial epilepsy. We recorded prescription patterns, quality of life (QoL) using the QoL scale in childhood epilepsy (CAVE) and use of resources. 134 patients were under treatment with oxcarbazepine (72.4 %), with a mean dose of 22.3 mg/kg/day; standard deviation (SD): 8.04; 95 % confidence interval (CI): 20.9 to 23.7, and 51 (27.6%) with carbamazepine, mean dose of 14 mg/kg/day; SD: 6.2; 95 % CI: 12.3 to 15.8. A total of 19.4% and 21.6 %, respectively, followed multiple drug treatment. The mean scores on functional dimensions of CAVE were (out of 5): school attendance: 4.5; SD: 0.7; social relationships: 4.1; SD: 0.9, and autonomy: 3.9; SD: 1.9. Patients receiving multiple drug therapy had worse results in quality of life (p used in lower doses than recommended and the dosing is not adjusted for weight. Underdosing may lead to regimes of multiple drug therapy that should be reviewed individually.

To assess the pattern of prenatal care utilization in Tehran in 2015. A total of 2005 pregnant women who lived in the catchment area of the study participated. Participants were followed from the sixth week of pregnancy until birth. Data were collected either through interviews or from written medical records. More than 95% of mothers completed all eight prenatal care visits. Some 99% of mothers completed at least four visits. The prenatal care utilization was equal among all different socio-economic regions in Tehran. Gynecologists were the main healthcare providers in prenatal care visits. In addition, 75% of mothers went to gynecologists at their office or in hospitals for ordering first-trimester screening tests. Prenatal care utilization complied with both national guidelines and recommendations of World Health Organization regarding the number of conducted visits. Equal accessibility and availability of prenatal care service despite the socio-economical differences of families is suggestive of equity and social justice in terms of providing health services in both public and private sectors. Among healthcare providers, gynecologists were the main healthcare provider for prenatal care visits. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

National health security requires that healthcare facilities be prepared to provide rapid, effective emergency and trauma care to all patients affected by a catastrophic event. We sought to quantify changes in healthcare utilization patterns for an at-risk Medicare population before, during, and after Superstorm Sandy's 2012 landfall in New Jersey (NJ). This study is a retrospective cohort study of Medicare beneficiaries impacted by Superstorm Sandy. We compared hospital emergency department (ED) and healthcare facility inpatient utilization in the weeks before and after Superstorm Sandy landfall using a 20% random sample of Medicare fee-for-service beneficiaries continuously enrolled in 2011 and 2012 (N=224,116). Outcome measures were pre-storm discharges (or transfers), average length of stay, service intensity weight, and post-storm ED visits resulting in either discharge or hospital admission. In the pre-storm week, hospital transfers from skilled nursing facilities (SNF) increased by 39% and inpatient discharges had a 0.3 day decreased mean length of stay compared to the prior year. In the post-storm week, ED visits increased by 14% statewide; of these additional "surge" patients, 20% were admitted to the hospital. The increase in ED demand was more than double the statewide average in the most highly impacted coastal regions (35% versus 14%). Superstorm Sandy impacted both pre- and post-storm patient movement in New Jersey; post-landfall ED surge was associated with overall storm impact, which was greatest in coastal counties. A significant increase in the number and severity of pre-storm transfer patients, in particular from SNF, as well as in post-storm ED visits and inpatient admissions, draws attention to the importance of collaborative regional approaches to healthcare in large-scale events.

This is an observational study of fluorescein angiography (FA) in consecutive patients with rhegmatogenous retinal detachment (RRD) in Changhua Christian Hospital to investigate the peripheral retinal vascular patterns in those patients. All patients had their age, sex, axial length (AXL), and refraction status (RF) recorded. According to the findings in FA of the peripheral retina, the eyes were divided into 4 groups: in group 1, there was a ramified pattern of peripheral retinal vasculature with gradual tapering; in group 2, there was an abrupt ending of peripheral vasculature with peripheral non-perfusion; in group 3, there was a curving route of peripheral vasculature forming vascular arcades or anastomosis; and in group 4, the same as in group 3, but with one or more wedge-shaped avascular notches. Comparisons of age, sex, AXL, and RF, association of breaks with lattice degeneration and retinal non-perfusion, surgical procedures utilized, and mean numbers of operations were made among the four groups. Of the 73 eyes studied, there were 13 eyes (17.8%) in group 1, 3 eyes (4.1%) in group 2, 40 eyes (54.8%) in group 3 and 17 eyes (23.3%) in group 4. Significant differences in age, AXL and RF, and association of retinal breaks to non-perfusion were noted among the four groups. Patients in group 1 had older ages, while younger ages were noted in groups 3 and 4. Eyes in group 1 had the shortest average AXL and were least myopic in contrast to the eyes in groups 3 and 4. Association of retinal breaks and retinal non-perfusion was significantly higher in groups 2, 3 and 4 than in group 1. In conclusion, peripheral vascular anomalies are common in cases with RRD. Patients with peripheral non-perfusion tend to be younger, with longer axial length and have the breaks associated with retinal non-perfusion. PMID:26909812

The University of Ghana Medical School (UGMS) Clinic provides healthcare service which is free at point of service to students, staff, retired staff and dependents of staff of the College of Health Sciences. However, since 1983, no in-depth review of health service provision or utilization has been undertaken. This study reviewed client characteristics, utilization and disease patterns at the clinic and also compared the disease patterns to that of other primary health facilities nationwide. This was an analytical cross-sectional study undertaken at the UGMS clinic in Korle-Bu. It was a retrospective review of records of all clients attending the facility from January 2002 to December, 2004. More males than females attended the clinic and majority (63.9%) of clients were between 15-44 years (median age was 26 years). Dependents of staff constituted the highest attendants (41%) to the clinic. Among staff, junior staffs were in the majority. Malaria, respiratory tract infection and musculoskeletal pain were the most common conditions seen. Overall, 83% of clients were treated and discharged per visit without the need for review visits. Dependents of staff used the facility the most and they live in many different part of the city of Accra, and to ask them to attend the clinic for care is not efficient. It will be better to provide or supplement their securing of insurance so that they could access health care close to their homes and save time and attention to students and staff.

Careful research that elucidates how behavior relates to design in the context of elementary school grounds can serve to guide cost-efficient design with the goal of encouraging physical activity (PA). This work explores patterns in children's PA behavior within playground spaces with the specific goal of guiding healthy playground design. Data on children's utilization and PA behavior in 6 playgrounds divided into 106 observation zones were collected in 2005 and 2006 at Denver elementary school playgrounds using the System for Observing Play and Leisure Activity in Youth. Analyses of variance and t tests determined whether there were differences in utilization and behavior patterns across observations zones and between genders. This study provides evidence that children prefer to use certain types of playground zones and that they are more likely to practice moderate-to-vigorous physical activity (MVPA) in some zones. The authors observed statistically significant differences between genders. Boys were more likely to engage in MVPA in zones without equipment, girls were more likely to use zones with equipment. This work suggests that the inclusion or omission of specific playground features may have an impact on the way that children use the spaces.

Full Text Available Background/Aim. The analysis of drug prescribing in general practice in Serbia showed that the use of benzodiazepines is most frequently associated with hypertension. The aim of this study was to establish the correlation of the characteristics of patients with hypertension to antihypertensive drug therapy, and the intake of benzodiazepines. Methods. A special questionnaire was used for interviewing the patients (n = 171 chronically treated for hypertenson. Statistical tests used were χ2-test and Student's t-test. Results. No differences were noted in terms of age, gender, education, body weight, smoking habits and blood pressure (155±4.9/100±2.7 mmHg vs. 160±2.2/105±3.7 mmHg, between the group I (antihypertensive drugs+benzodiazepines: n = 79, and the group II (antihypertensives only: n = 92. The patients taking benzodiazepines received a lower number of different antihypertensive drugs (2.3±0.09 vs. 2.7±0.10; p < 0.01, but the total antihypertensive drug load was significantly greater than in the group II (2.6±0.10 vs. 1.9±0.15 defined daily doses (DDD/patient/day; p < 0.01. Benzodiazepines were taken for anxiety (62% and hypertension (21%, rarely for insomnia, mostly once a day, at bedtime. About half the patients took benzodiazepines regularly for months or years aware of the risk for addiction. Diazepam was used by 82% of the patients. The average daily exposure to benzodiazepines was 0.45±0.05 DDD/patient/day. The drug was bought without prescription in 25% of the patients, and without consulting a physician in 12% of them. Conclusion. The study confirmed a close association of hypertension with the use of benzodiazepines. The frequent use of benzodiazepines in the patients with hypertension might be caused by an inadequate response to antihypertensive drug therapy, besides anxiety and insomnia. The therapeutic efficacy of a long-term use of low doses of benzodiazepines in hypertension requires further investigation.

Purpose: To determine quality of life (QOL) and health utility in irradiated laryngeal cancer survivors. Materials and Methods: Over 6 months, consecutive follow-up patients at a comprehensive cancer centre completed the QOL questionnaire FACT-H and N and the time trade-off (TTO) utility instrument. Results: Inclusion criteria were met by 339 patients, of whom 269 were eligible, 245 were approached, and 120 agreed to participate. Most participants were men (83%) who had received radiotherapy (97%) for Stage I disease (53%) of the glottis (75%); 7% had undergone total laryngectomy. Participants differed from nonparticipants only in being younger (mean age, 65 vs. 68 years, p = 0.0049) and having higher performance status (Karnofsky 88 vs. 84, p = 0.0012). The average scores for FACT-H and N and the TTO were 124/144 (SD, 14) and 0.90/1.0 (SD, 0.16) respectively. FACT-H and N score was more highly correlated with Karnofsky score (r = 0.43, p = 0.001) than with the TTO (r = 0.29, p = 0.002). Gender predicted QOL (means: M = 125, F 118), while natural speech, no relapses, and more time since initial treatment predicted higher utility. Conclusion: The QOL of irradiated laryngeal cancer survivors was reasonably high and independent of initial disease variables. The QOL questionnaire correlated more strongly with performance status than with utility, suggesting that QOL and utility measures may be perceived differently by patients

HIV infected patients should be expected in the Sudanese dental health care services with an increasing frequency. Dental care utilization in the context of the HIV epidemic is generally poorly understood. Focusing on Sudanese dental patients with reported unknown HIV status, this study assessed the extent to which Andersen's model in terms of predisposing (socio-demographics), enabling (knowledge, attitudes and perceived risk related to HIV) and need related factors (oral health status) predict dental care utilization. It was hypothesized that enabling factors would add to the explanation of dental care utilization beyond that of predisposing and need related factors. Dental patients were recruited from Khartoum Dental Teaching Hospital (KDTH) and University of Science and Technology (UST) during March-July 2008. A total of 1262 patients (mean age 30.7, 56.5% females and 61% from KDTH) were examined clinically (DMFT) and participated in an interview. A total of 53.9% confirmed having attended a dental clinic for treatment at least once in the past 2 years. Logistic regression analysis revealed that predisposing factors; travelling inside Sudan (OR = 0.5) were associated with lower odds and females were associated with higher odds (OR = 2.0) for dental service utilization. Enabling factors; higher knowledge of HIV transmission (OR = 0.6) and higher HIV related experience (OR = 0.7) were associated with lower odds, whereas positive attitudes towards infected people and high perceived risk of contagion (OR = 1.3) were associated with higher odds for dental care utilization. Among need related factors dental caries experience was strongly associated with dental care utilization (OR = 4.8). Disparity in the history of dental care utilization goes beyond socio-demographic position and need for dental care. Public awareness of HIV infection control and confidence on the competence of dentists should be improved to minimize avoidance behaviour and help establish dental

Palliative care is recommended for advanced heart failure (HF) by several major societies, though prior studies indicate that it is underutilized. To investigate patterns of palliative care referral for patients admitted with HF exacerbations, as well as to examine patient and hospital factors associated with different rates of palliative care referral. Retrospective nationwide cohort analysis utilizing the National Inpatient Sample from 2006 to 2012. Patients referred to palliative care were compared to those who were not. Patients ≥18 years of age with a primary diagnosis of HF requiring mechanical ventilation (MV) were included. A cohort of non-HF patients with metastatic cancer was created for temporal comparison. Between 2006 and 2012, 74 824 patients underwent MV for HF. A referral to palliative care was made in 2903 (3.9%) patients. The rate of referral for palliative care in HF increased from 0.8% in 2006 to 6.4% in 2012 ( P care referral in patients with cancer increased from 2.9% in 2006 to 11.9% in 2012 ( P care ( P care. The use of palliative care for patients with advanced HF increased during the study period; however, palliative care remains underutilized in this setting. Patient factors such as race and SES affect access to palliative care.

Background: Utilization of health services is the actual attendance by the members of the public at health care facilities to receive care. Utilization, serves as an important tool for oral health policy decision-making. The aim of the present study was to retrospectively gauge and assess the utilization pattern of the dental treatments which was given in hospital for last 10 years. Materials and Methods: This retrospective infirmary based study was carried out at Sheri Kashmir Institute of Medical Sciences (SKIMS), Srinagar, Jammu and Kashmir, India. The yearly outpatient department (OPD) records for the utilization of specific dental treatment of a total of 103963 patients were assessed retrospectively from 2014 to 2003. Trend analysis was used to assess the trend of utilization of each speciality with best fitted linear trend lines. Results: The pattern of new patients has also shown a constant rise during the study period except for 2008 and 2009. The utilization of oral surgery speciality has shown a tremendous fall from 2003 to 2014 whereas the number of patients coming to periodontics and conservative dentistry has shown an increasing pattern. Conclusion: Utilization of oral health care has long been used as an indicator of oral health related behaviour of a population. In the present study it can be conclude that the outlook of the population under study has changed from blood and vulcanite dentistry outlook and is moving towards restorative dentistry. .

The observed features in the temporal response patterns of a temperature-modulated chemoresistive gas sensor were used for gas diagnosis. The patterns were recorded for clean air and air contaminated with different levels of some volatile organic compounds while a staircase heating voltage waveform had been applied to the microheater of a tin oxide gas sensor that modulated its operating temperature. Combining the steady-state and transient parameters of the recorded responses in the 50-400 deg. C range resulted in discriminatory feature vectors which were utilized for contaminant classification. The information content of these feature vectors was proved sufficient for discrimination of methanol, ethanol, 1-butanol, and acetone contaminations in a wide concentration range.

Utility of visual impairment caused by amblyopia is important for the cost-effectiveness of screening for amblyopia (lazy eye, prevalence 3-3.5 %). We previously measured decrease of utility in 35-year-old persons with unilateral persistent amblyopia. The current observational case-control study aimed to measure loss of utility in patients with amblyopia with recent decrease of vision in their better eye. As these patients are rare, the sample was supplemented by patients with bilateral age-related macular degeneration with similar decrease of vision. From our out-patient department, two groups of patients with recent deterioration to bilateral visual acuity less than Snellen 0.5 (bilateral visual impairment, BVI) were recruited, with either persistent amblyopia and age-related macular degeneration (AMB + AMD), or with bilateral age-related macular degeneration (BAMD). To measure utility, the time trade-off method and the standard gamble method were applied through interviews. Correlations were sought between utility values and visual acuity, age and Visual Function Questionnaire-25 scores. Seventeen AMB + AMD patients (mean age 72.9 years), and 63 BAMD patients (mean age 79.6 years) were included in the study. Among AMB + AMD, 80 % were willing to trade lifetime in exchange for cure. The overall mean time trade-off utility was 0.925. Among BAMD, 75 % were willing to trade, utility was 0.917. Among AMB + AMD, 38 % accepted risk of death in exchange for cure, overall mean standard gamble utility was 0.999. Among BAMD, 49 % accepted risk of death, utility was 0.998. Utility was not related to visual acuity but it was to age (p = 0.02). Elderly patients with BVI, caused by persistent amblyopia and age-related macular degeneration (AMD) or by bilateral AMD, had an approximately 8 % loss of TTO utility. Notably, the 8 % loss in elderly with BVI differs little from the 3.7 % loss we found previously in 35-year-old persons with unilateral

Purpose: To investigate the influence of continuous table motion on patient breathing patterns for compensation of moving targets by a robotic treatment couch. Methods and Materials: Fifteen volunteers were placed on a robotic treatment couch, and the couch was moved on different breathing-correlated and -uncorrelated trajectories. External abdominal breathing motion of the patients was measured using an infrared camera system. The influence of table motion on breathing range and pattern was analyzed. Results: Continuous table motion was tolerated well by all test persons. Volunteers reacted differently to table motion. Four test persons showed no change of breathing range and pattern. Increased irregular breathing was observed in 4 patients; however, irregularity was not correlated with table motion. Only 4 test persons showed an increase in mean breathing amplitude of more than 2mm during motion of the couch. The mean cycle period decreased by more than 1 s for 2 test persons only. No abrupt changes in amplitude or cycle period could be observed. Conclusions: The observed small changes in breathing patterns support the application of motion compensation by a robotic treatment couch.

The objective of this retrospective analysis was to assess the correlation of comorbid depression and/or anxiety to patterns of treatment, healthcare utilization, and associated costs among diabetic peripheral neuropathic pain (DPNP) patients, employing a large US administrative claims database. Patients under age 65 with commercial insurance and patients aged 65 and older with employer-sponsored Medicare supplemental insurance were selected for the study if they had at least one diagnosis of DPNP in 2005. The first observed DPNP claim was considered the 'index date.' All individuals had a 12-month pre-index and 12-month follow-up period. For both populations, two subgroups were constructed for individuals with depression and/or anxiety (DPNP-DA cohort) or without these disorders (DPNP-only cohort). Patients' demographic characteristics, clinical characteristics, and medication use were compared over the pre-index period. Healthcare expenditures and resource utilization were measured for the post-index period. Two-part models were used to examine the impact of comorbid depression and/or anxiety on healthcare utilization and costs, controlling for demographic and clinical characteristics. The study identified 11,854 DPNP-only and 1512 DPNP-DA patients in the Medicare supplemental cohort, and 11,685 and 2728 in the commercially insured cohort. Compared to DPNP-only patients over the follow-up period, a significantly higher percentage of DPNP-DA patients were dispensed pain and DPNP-related medication. All components of healthcare utilization, except home healthcare visits and physician office visits, were more likely to be provided to DPNP-DA patients versus the DPNP-only cohort (all p bias between study cohorts, mis-identification of DPNP and/or depression, and inability to assess indirect costs as well as use and cost of over-the-counter medications. These findings indicate that the healthcare costs were significantly higher for DPNP patients comorbid with

Purpose: There are multiple current strategies for breast radiotherapy (RT). The alignment of physician practice patterns with best evidence and patient preferences will enhance patient autonomy and improve cancer care. However, there is little information describing patient preferences for breast RT and physician practice patterns. Methods and Materials: Using a reliable and valid instrument, we assessed the preferences of 5,000 randomly selected women (with or without cancer) undergoing mammography. To assess practice patterns, 2,150 randomly selected physician-members of American Society for Radiation Oncology were surveyed. Results: A total of 1,807 women (36%) and 363 physicians (17%) provided usable responses. The 95% confidence interval is < ±2.3% for patients and < ±5.3% for physicians. Patient preferences were hypofractionated whole breast irradiation (HF-WBI) 62%, partial breast irradiation (PBI) 28%, and conventionally fractionated whole breast irradiation (CF-WBI) 10%. By comparison, 82% of physicians use CF-WBI for more than 2/3 of women and 56% never use HF-WBI. With respect to PBI, 62% of women preferred three-dimensional (3D)-PBI and 38% favor brachytherapy-PBI, whereas 36% of physicians offer 3D-PBI and 66% offer brachytherapy-PBI. 70% of women prefer once-daily RT over 10 days vs. twice-daily RT over 5 days. 55% of physicians who use PBI do not offer PBI on clinical trial. Conclusions: HF-WBI, while preferred by patients and supported by evidence, falls behind the unproven and less preferred strategy of PBI in clinical practice. There is a discrepancy between women’s preferences for PBI modality and type of PBI offered by physicians. Further alignment is needed between practice patterns, patient preferences, and clinical evidence.

To characterize the velopharyngeal closure patterns and speech performance among submucous cleft palate patients. Patients with submucous cleft palate visiting the Department of Cleft Lip and Palate Surgery, West China Hospital of Stomatology, Sichuan University between 2008 and 2016 were reviewed. Outcomes of subjective speech evaluation including velopharyngeal function, consonant articulation, and objective nasopharyngeal endoscopy including the mobility of soft palate, pharyngeal walls were retrospectively analyzed. A total of 353 cases were retrieved in this study, among which 138 (39.09%) demonstrated velopharyngeal competence, 176 (49.86%) velopharyngeal incompetence, and 39 (11.05%) marginal velopharyngeal incompetence. A total of 268 cases were subjected to nasopharyngeal endoscopy examination, where 167 (62.31%) demonstrated circular closure pattern, 89 (33.21%) coronal pattern, and 12 (4.48%) sagittal pattern. Passavant's ridge existed in 45.51% (76/167) patients with circular closure and 13.48% (12/89) patients with coronal closure. Among the 353 patients included in this study, 137 (38.81%) presented normal articulation, 124 (35.13%) consonant elimination, 51 (14.45%) compensatory articulation, 36 (10.20%) consonant weakening, 25 (7.08%) consonant replacement, and 36 (10.20%) multiple articulation errors. Circular closure was the most prevalent velopharyngeal closure pattern among patients with submucous cleft palate, and high-pressure consonant deletion was the most common articulation abnormality. Articulation error occurred more frequently among patients with a low velopharyngeal closure rate.

All published studies of health care utilization in gout have been cross-sectional to date, and most used a patient-reported diagnosis of gout. Our objective was to assess health care utilization and its predictors in patients with physician-confirmed gout in a prospective cohort study. In a multi-center prospective cohort study of U.S. veterans with rheumatologist-confirmed gout (N = 186; two centers), we assessed patient self-reported overall and gout-specific health care utilization with the Gout Assessment Questionnaire (GAQ) every 3-months for a 9-month period. Comparisons were made using the student's t test or the chi-square, Wilcoxon rank sum test or Fisher exact test, as appropriate. Mixed effects Poisson regression was used to assess potential correlates of gout-related health care utilization. Mean age was 64.6 years, 98% were men, 13% Hispanic or Latino, 32% were African-American, 6% did not graduate high school, mean serum urate was 8.3 and mean Deyo-Charlson score was 3.1. During the past year, mean gout-related visits were as follows: rheumatologist, 1.5; primary care physician, 2 visits; ≥1 inpatient visits, 7%; ≥1 ER visits, 26%; and urgent care/walk-in visit, 33%. In longitudinal analyses, African-American race and gout flares in the last 3 months were associated with significantly higher rate ratio of gout-related outpatient visits. African-American race and lack of college education were associated with significantly higher rate ratio for gout-related urgent visits and overnight stays. African-American race and recent gout flares were associated with higher outpatient utilization and African-American race and no college education with higher urgent or inpatient utilization. Future studies should examine whether modifiable predictors of utilization can be targeted to reduce healthcare utilization in patients with gout.

Full Text Available Identifying temporal variation in hospitalization rates may provide insights about disease patterns and thereby inform research, policy, and clinical care. However, the majority of medical conditions have not been studied for their potential seasonal variation. The objective of this study was to apply a data-driven approach to characterize temporal variation in condition-specific hospitalizations. Using a dataset of 34 million inpatient discharges gathered from hospitals in New York State from 2008-2011, we grouped all discharges into 263 clinical conditions based on the principal discharge diagnosis using Clinical Classification Software in order to mitigate the limitation that administrative claims data reflect clinical conditions to varying specificity. After applying Seasonal-Trend Decomposition by LOESS, we estimated the periodicity of the seasonal component using spectral analysis and applied harmonic regression to calculate the amplitude and phase of the condition's seasonal utilization pattern. We also introduced four new indices of temporal variation: mean oscillation width, seasonal coefficient, trend coefficient, and linearity of the trend. Finally, K-means clustering was used to group conditions across these four indices to identify common temporal variation patterns. Of all 263 clinical conditions considered, 164 demonstrated statistically significant seasonality. Notably, we identified conditions for which seasonal variation has not been previously described such as ovarian cancer, tuberculosis, and schizophrenia. Clustering analysis yielded three distinct groups of conditions based on multiple measures of seasonal variation. Our study was limited to New York State and results may not directly apply to other regions with distinct climates and health burden. A substantial proportion of medical conditions, larger than previously described, exhibit seasonal variation in hospital utilization. Moreover, the application of clustering

Full Text Available Background: Cardiovascular diseases (CVDs are the most common cause of disease-related death in Saudi Arabia. The incidence of CVDs continues to increase, presenting a major health care problem. Nonprescription medications are widely used by patients with CVD and may cause adverse drug events, either by worsening the disease or by harmfully interacting with prescribed medications. We investigated the patterns of nonprescription medication utilization and the factors associated with their use in patients with CVD. Methods: This was a cross-sectional study conducted at the Cardiology Clinics of an academic tertiary health care center. Participants were asked about their sociodemographic characteristics, medical history and frequency of using nonprescription medications including over-the-counter (OTC products, dietary supplements, and herbal products. Moreover, we investigated the participants’ sources of information about nonprescription medications. Multivariate logistic regression analysis was conducted to examine the predictors of nonprescription medication use. Results: A total of 209 participants were interviewed. The mean age of the participants was 56 ± 15 years, and 110 (52.6% were female. Of the 209 participants, 116 (55% reported routine use of nonprescription medications. Black seeds and garlic were the most frequently used herbal products. Acetaminophen, cold/cough remedies, and ibuprofen were the most commonly reported OTC drugs. Of the surveyed patients, 54 (46.5% used nonprescription medications to manage cardiovascular conditions specifically. Compared with other comorbidities, diabetes mellitus was associated with a higher use of nonprescription medications. Conclusion: In patients with CVD, the routine use of nonprescription medications was common for a number of reasons. Health care providers should proactively discuss nonprescription use with their CVD patients to avoid potential harmful outcomes. Keywords

To evaluate prescribing pattern of antihypertensive in T2DM (type 2 diabetes patients and compare with existing recent guidelines. Methods. A cross-sectional study involving evaluation of all T2DM patients referred to endocrinology unit at tertiary care centre for hypertension, comorbid complications, and recording prescription. Utilization of 5 different antihypertensive drug classes was compared for all patients receiving 1, 2, 3, 4, or more drugs. Logistical regression was used to assess likelihood of prescription of drugs and/or therapy for specific conditions mentioned in the guidelines. Results. Out of 1358, T2DM enrolled patients 1186 (87% had hypertension (males 52%, females 48%. The median duration (IQ of hypertension diabetics was 4 (1–10 years. A total of 25% patients had controlled BP and 75% with uncontrolled blood pressure (13% isolated systolic hypertension, 6% isolated diastolic hypertension, and 55% both elevated. Overall, ACE inhibitors (ACEIs were prescribed the highest (59% followed by angiotensin receptor blockers (ARBs (52%, calcium channel blockers (CCBs (29%, diuretics (27%, and beta-blockers (14%. Overall, 55% of T2DM patients were on polytherapy, 41% on monotherapy, and 4% had no antihypertensive treatment. Polytherapy was more predominant with age, duration of diabetes, duration of hypertension, and comorbid complications. Conclusion. Although prescribing pattern of antihypertensive showed adherence to existing evidence-based guidelines, higher proportion of uncontrolled hypertensive patients was found.

Background and Purpose. To determine whether the pattern of iron deposition in the fascicula nigrale in patients with Parkinson's disease would be different from age-matched controls by utilizing quantitative susceptibility mapping to measure susceptibility change. Methods. MRIs of the brain were obtained from 34 subjects, 18 with Parkinson's disease and 16 age- and gender-matched controls. Regions of interest were drawn around the fascicula nigrale and substantia nigra using SWI mapping software by blinded investigators. Statistical analyses were performed to determine susceptibility patterns of both of these regions. Results. Measurements showed significantly increased susceptibility in the substantia nigra in Parkinson's patients and an increased rostral-caudal deposition of iron in the fascicula nigrale in all subjects. This trend was exaggerated with significant correlation noted with increasing age in the Parkinson group. Conclusion. The pattern of an exaggerated iron deposition gradient of the fascicula nigrale in the Parkinson group could represent underlying tract dysfunction. Significant correlation of increasing iron deposition with increasing age may be a cumulative effect, possibly related to disease duration

Full Text Available Abstract Background Universal access is one of the major aims in public health and social care. Services should be provided on the basis of individual needs. However, municipal autonomy and the fragmentation of services may jeopardize universal access and lead to variation between municipalities in the delivery of services. This paper aims to identify patient-level characteristics and municipality-level service patterns that may have an influence on the use and costs of health and social services of frail elderly patients. Methods Hierarchical analysis was applied to estimate the effects of patient and municipality-level variables on services utilization. Results The variation in the use of health care services was entirely due to patient-related variables, whereas in the social services, 9% of the variation was explained by the municipality-level and 91% by the patient-level characteristics. Health-related quality of life explained a major part of variation in the costs of health care services. Those who had reported improvement in their health status during the preceding year were more frequent users of social care services. Low informal support, poor functional status and poor instrumental activities of daily living, living at a residential home, and living alone were associated with higher social services expenditure. Conclusions The results of this study showed municipality-level variation in the utilization of social services, whereas health care services provided for frail elderly people seem to be highly equitable across municipalities. Another important finding was that the utilization of social and health services were connected. Those who reported improvement in their health status during the preceding year were more frequently also using social services. This result suggests that if municipalities continue to limit the provision of support services only for those who are in the highest need, this saving in the social sector may, in

A potentially important factor yet to receive adequate study is the time when hospital falls occur. A prior study conducted before the system-wide introduction of preventive measures revealed a biphasic 24-hour pattern of hospital falls with major peak in the morning. The purpose was to identify the temporal patterning of falls among elderly patients in hospitals with comprehensive fall prevention programs in place. A 4-year observational study was conducted by the local health authority in the five nonteaching public hospitals located in the province of Ferrara, Italy. Fall records involving patients of ages ≥65 years hospitalized in the general medical departments were used. Single- and multiple-component cosinor (time series) analyses were used to explore 24-hour, weekly, and annual patterns of falls. A total of 763 falls were experienced by 709 different elderly hospitalized patients. Falls typically took place in the patient's hospital room (72%) and bathroom (23%). Major causes were patient instability (32%) and accident (13%), and most occurred when not wearing footwear (45%) or wearing inappropriate sling-back open-toe shoes (39%). Falls happened while standing (39%), while seated (21%), and while getting into, out of, or laying in bed (32%)-either with the bed rails raised or lowered. Fall outcome usually involved no injury (58%) or slight injury (35%), but some (7%) were disabling. Fall occurrence was higher during the night (46%) compared to either the morning (30%) or afternoon (24%) shift. Patterns across 24 hours were characterized by a single major and one or more minor peaks that seemed to be associated with a variety of scheduled patient, hospital, and nursing activities. Multiple-component cosinor analysis identified significant (p footwear. Falls were more frequent, but not significantly so, on Fridays, Sundays, and Mondays compared with Tuesdays, and were more frequent in winter and spring (p = .003).

We measured local cerebral glucose utilization in 19 patients with Lennox-Gastaut syndrome (LG), partial seizures (PS), atypical and classical phenylketonuria (PKU), Leigh disease, and subacute sclerosing panencephalitis (SSPE), using positron emission tomography (PET). The mean values of regional glucose utilization in interictal scans of LG were significantly reduced in all brain regions when compared with that of PS (P<0.005). PET studies of glucose utilization in LG revealed more widespread hypometabolism than in PS. Two sibling with dihydropteridine reductase deficiency, a patient with classical PKU, and a boy with cytochrome c oxidase deficiency showed reduced glucose utilization in the caudate and putamen. A marked decrease in glucose utilization was found in the cortical gray matter of a patient with rapidly progressive SSPE, despite relatively preserved utilization in the caudate and putamen. The PET study of a patient with slowly progressive SSPE revealed patterns and values of glucose utilization similar to those of the control. Thus, PET provided a useful clue toward understanding brain dysfunction in LG, PS, PKU, Leigh disease, and SSPE. (orig.)

Full Text Available Abstract Background The purpose of our study was to determine characteristics that influence the utilization of non-conventional hemodialysis (NCHD therapies and its subtypes (nocturnal (NHD, short daily (SDHD, long conventional (LCHD and conventional hemodialysis (CHD as well as provider attitudes regarding the evidence for NCHD use. Methods An international cohort of subscribers of a nephrology education website http://www.nephrologynow.com was invited to participate in an online survey. Non-conventional hemodialysis was defined as any forms of hemodialysis delivered > 3 treatments per week and/or > 4 hours per session. NHD and SDHD included both home and in-centre. Respondents were categorized as CHD if their centre only offered conventional thrice weekly hemodialysis. Variables associated with NCHD and its subtypes were determined using multivariate logistic regression analysis. The survey assessed multiple domains regarding NCHD including reasons for initiating and discontinuing, for not offering and attitudes regarding evidence. Results 544 surveys were completed leading to a 15.6% response rate. The final cohort was limited to 311 physicians. Dialysis modalities utilized among the respondents were as follows: NCHD194 (62.4%, NHD 83 (26.7%, SDHD 107 (34.4%, LCHD 81 (26% and CHD 117 (37.6%. The geographic regions of participants were as follows: 11.9% Canada, 26.7% USA, 21.5% Europe, 6.1% Australia/New Zealand, 10% Africa/Middle East, 10.9% Asia and 12.9% South America. Variables associated with NCHD utilization included NCHD training (OR 2.47 CI 1.25-4.16, government physician reimbursement (OR 2.66, CI 1.11-6.40, practicing at an academic centre (OR 2.28 CI 1.25-4.16, higher national health care expenditure and number of ESRD patients per centre. Hemodialysis providers with patients on NCHD were significantly more likely to agree with the statements that NCHD improves quality of life, improves nutritional status, reduces EPO requirements

To assess the influence of craniopharyngioma or consequent surgery on melatonin secretion, and the association with fatigue, sleepiness, sleep pattern and sleep quality. Cross-sectional study. A total of 15 craniopharyngioma patients were individually matched to healthy controls. In this study, 24-h salivary melatonin and cortisol were measured. Sleep-wake patterns were characterised by actigraphy and sleep diaries recorded for 2 weeks. Sleepiness, fatigue, sleep quality and general health were assessed by Multidimensional Fatigue Inventory, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale and Short-Form 36. Patients had increased mental fatigue, daytime dysfunction, sleep latency and lower general health (all, P≤0.05), and they tended to have increased daytime sleepiness, general fatigue and impaired sleep quality compared with controls. The degree of hypothalamic injury was associated with an increased BMI and lower mental health (P=0.01). High BMI was associated with increased daytime sleepiness, daytime dysfunction, mental fatigue and lower mental health (all, P≤0.01). Low midnight melatonin was associated with reduced sleep time and efficiency (P≤0.03) and a tendency for increased sleepiness, impaired sleep quality and physical health. Midnight melatonin remained independently related to sleep time after adjustment for cortisol. Three different patterns of melatonin profiles were observed; normal (n=6), absent midnight peak (n=6) and phase-shifted peak (n=2). Only patients with absent midnight peak had impaired sleep quality, increased daytime sleepiness and general and mental fatigue. Craniopharyngioma patients present with changes in circadian pattern and daytime symptoms, which may be due to the influence of the craniopharyngioma or its treatment on the hypothalamic circadian and sleep regulatory nuclei. © 2014 European Society of Endocrinology.

Pressure ulcer (PU) is a localized trauma to the skin and or tissue beneath which lies in bony prominence due to pressure or pressure that combines with a sharp surface. Several studies have found that PU is a common problem in pediatrics population. Infection at the site of a PU is the most common complication in which the PU may host a resistant microorganism and may turn into a local infection that will be the source of bacteremia in hospitalized patients. To reveal which is the most common microbial species that underlie in pressure ulcer of pediatrics patients.A cross-sectional study was conducted in July-September 2017, involving 18 PU pediatric patients in Haji Adam Malik Hospital. To each subject, swab culture from the ulcer was madein microbial laboratory in Haji Adam Malik Hospital to determine the microbial pattern. This study found that the most common microbial pattern in pressure ulcers of pediatrics patient in Haji Adam Malik Hospital is Acinetobacter baumannii (22.2%).

Differences in treatment patterns, health care resource utilization, and costs between patients with castration-resistant prostate cancer (CRPC) treated by oncologists and those treated by urologists were examined. Patients aged ≥40 with CRPC were identified using claims from a large US managed health care plan between July 2001 and December 2007. A 6-month baseline period was used to assess patient characteristics. Patients with visits to an urologist, without visits to an oncologist, were assigned to the urology cohort, and patients with visits to an oncologist, with or without visits to an urologist, were assigned to the oncology cohort. Treatment patterns, health care resource utilization, and costs during a variable follow-up period were compared between cohorts using descriptive statistics and Lin’s regression. The urology cohort had fewer comorbid illnesses (P < 0.001) and patients were less likely to have other cancers during baseline (P < 0.001) or to die during follow-up (P = 0.004) compared with the oncology cohort. The oncology cohort patients were significantly more likely to have a claim for hormones (74.5% vs 61.1%; P < 0.001), chemotherapy (46.9% vs 10.2%, P < 0.001), and radiation (22.3% vs 3.7%, P < 0.0001) over follow-up. Mean unadjusted health care costs were higher in the oncology vs the urology cohort (US$31,896 vs US$15,318, respectively; P < 0.001). At 6 years follow-up, cumulative adjusted CRPC-specific costs were significantly higher among patients treated by oncologists with chemotherapy than among patients treated by urologists. CRPC patients treated by oncologists had greater use of hormones, chemotherapy, and radiation; higher percentages of patients with inpatient stays, emergency room, and ambulatory visits; and higher health care costs, than patients treated by urologists

2007-01-01

To determine the histological grading patterns in a cohort of hospitalized patients of cutaneous leishmaniasis. One hundred patients of Cutaneous Leishmaniasis (CL), admitted in dermatology wards at PNS Shifa Hospital, Karachi, were examined. Only admitted patients of all ages and both sexes were included in the study. Patients of CL, who had received or were receiving systemic treatment were excluded. The lesions having marked secondary bacterial infection were also excluded. Initial diagnosis was clinical. History of being to an endemic area supported the diagnosis. The lesions were divided in two groups. Early, with duration less than 03 months and late, with duration between 3 and 12 months. The clinical lesions were noted as nodules, plaques, ulcers, crusted ulcers, lupoid lesions and plaques with scarring. Three types of skin smears (slit skin smear, saline aspirate smear and dab smear) were taken and examined with Giemsa stain. Cultures were performed on Nicolle-Novy-MacNeal (NNN) culture medium from Defense Scientific and Technology Organization (DESTO) Lab., Pakistan. Incisional skin biopsies were done. The biopsy specimens were examined by hemotoxylin and eosin stain (H and E stain). The number of Leishmania Tropica (LT) bodies was graded according to modified Ridley's parasitic index 1983. Clinical features were correlated with the histological patterns. Five histological patterns were identified in current study: 1) diffuse dermal infiltration without necrosis, 2) patchy dermal infiltration, 3) diffuse dermal infiltration with necrosis, 4) early reactive granuloma formation and 5) established epithelioid granuloma formation. LT bodies were identified in 75% of cases. Epidermal features were non-specific. The early lesions presented with diffuse infiltrate and late lesions showed granuloma formation. Five distinct types of histological patterns of CL have been recognized in this study. The early lesions presented with diffuse infiltrate and late lesions

Little is known regarding real-world health outcomes data among US psoriasis patients, but electronic health records (EHR) that collect structured data at point-of-care may provide opportunities to investigate real-world health outcomes among psoriasis patients. Our objective was to investigate patient-perceived treatment effectiveness, patterns of medication use (duration, switching, and/or discontinuation), healthcare resource utilization, and medication costs using real-world data from psoriasis patients. Data for adults (≥18-years) with a dermatology provider-given diagnosis of psoriasis from 9/2014-9/2015 were obtained from dermatology practices using a widely used US dermatology-specific EHR containing over 500,000 psoriasis patients. Disease severity was captured by static physician's global assessment and body surface area. Patient-perceived treatment effectiveness was assessed by a pre-defined question. Treatment switching and duration were documented. Reasons for discontinuations were assessed using pre-defined selections. Healthcare resource utilization was defined by visit frequency and complexity. From 82,621 patients with psoriasis during the study period, patient-perceived treatment effectiveness was investigated in 2200 patients. The proportion of patients reporting "strongly agree" when asked if their treatment was effective was highest for biologics (73%) and those reporting treatment adherence (55%). In 16,000 patients who received oral systemics and 21,087 patients who received biologics, median treatment duration was longer for those who received biologics (160 vs. 113 days, respectively). Treatment switching was less frequent among patients on systemic monotherapies compared to those on combination therapies. The most common reason for discontinuing biologics was loss of efficacy; the most common reason for discontinuing orals was side effects. In 28,754 patients, higher disease severity was associated with increased healthcare resource

To determine the referral pattern of dialysis patients to nephrologists and the effects of late referral on clinical, hematological and biochemical parameters in patients presenting for the first-time to dialysis center. This study was conducted on all patients of end stage renal diseases presenting for the first-time for undergoing hemodialysis at our center. Patients with acute renal failure were excluded from the study. At presentation, a history was taken from all the patients regarding seeking of nephrology services and referral pattern. Early and late referral was defined as the time of first referral or admission to a nephrologists greater or less than six months respectively before initiation of hemodialysis. All the patients were examined and their blood sample was drawn at the same time for routine hematological, biochemical parameters (urea, creatinine, serum potassium, calcium, phosphate and albumin) and viral markers (Anti HCV and HbsAg). In this study, 248 patients were enrolled, amongst them, 131 (52.8%) were male and 117 (47.2%) were female. Major causes of renal failure were diabetes mellitus, chronic glomerulonephritis and hypertension. Most of the patients were euvolemic and hypertensive. Sixty percent of patients were having very high urea (>200 mg/dl) and creatinine (>8.0 mg/dl). Most of the patients, 226 (91.1%), were anemic (Hemoglobin <11gm/dl) and 224 (90%) were hypoalbuminemic (serum albumin < 4gm/dl) on first presentation. Majority of patients were hyperkalemic, 139 (56.0%), hypocalcemic, 168 (67.7%) and serum phosphate level was high in only 117 (47%) patients. All the patients presented in emergency room to nephrologists at very late stage (100% late referral), when disease was very much advanced. All of them did not have permanent vascular access for hemodialysis on first presentation to dialysis center. Reasons for late referral were non-availability of nephrologists and nephrology services, non-renal doctors biased, unawareness and

Doppler ultrasonography of the hepatic vasculature is an integral part of evaluating precirrhotic and cirrhotic patients. While the reversal of the portal venous flow is a well-recognized phenomenon, other flow patterns, although not as easily understood, may play an important role in assessing the disease status. This article discusses the different characteristic flow patterns observed from the portal vein, hepatic artery, and hepatic vein in patients with liver cirrhosis or related complications and procedures. Knowledge of these different flow patterns provides additional information that may reinforce the diagnosis of cirrhosis, help in staging, and offer prognostic information for determining the direction of therapy. Doppler ultrasonography is invaluable when liver transplantation is being considered and aids in the diagnosis of cirrhosis and portal hypertension.

Traditional medicine (TM) has been established as a two-edged sword. On one edge numerous forms of TM have been proven safe and effective, while on the other edge various modes of TM have been shown to be futile and potentially dangerous. Resorting to TM, especially for chronic diseases, is common world-wide and includes Saudi Arabia. Most neurological diseases are chronic. No data is available on the utilization of TM among patients with neurological disorders. We conducted this study to assess for the prevalence, pattern, perception and triggers for TM use by the adult Saudi patients with neurological disorders. A survey written in Arabic and comprised of 15 questions was used to collect data on the practice of TM among the neurology patients of King Saud University Ambulatory Clinic. The questions in the survey pertain mainly to the frequency of TM practice, its form and the patient's opinion of this practice. The data was collected through a face to face interview by three medical students who were instructed on the survey questions prior to the launch of the study. 292 patients completed the survey (35.9% males and 64.0% females). 67% (n = 196) of the sample used TM. Cupping or what is commonly known as "hojamah" was the most prevalent method (45.4%) followed by herbs, skin cauterization and the Reciting of the Holy Quran (42.3%, 33.7% and 20.4% respectively). The prevalence of TM use did not differ across gender (chi-sq = 2.02; p-value = 0.15), level of education (chi-sq = 4.02; p-value = 0.40), health status (chi-sq = 2.29; p-value = 0.68), age groups (chi-sq = 5.12; p-value = 0.16), or perception toward TM (chi-sq = 2.67; p-value = 0.26) in this population. The practice of TM is common among the neurology patients of Saudi Arabia. Cupping, herbs, and skin cauterization, which can be harmful when wrongly employed, are frequently utilized in this patient population. Measures and policies to endorse the appropriate use of TM by Saudi society must be

Full Text Available This is an observational study of fluorescein angiography (FA in consecutive patients with rhegmatogenous retinal detachment (RRD in Changhua Christian Hospital to investigate the peripheral retinal vascular patterns in those patients. All patients had their age, sex, axial length (AXL, and refraction status (RF recorded. According to the findings in FA of the peripheral retina, the eyes were divided into 4 groups: in group 1, there was a ramified pattern of peripheral retinal vasculature with gradual tapering; in group 2, there was an abrupt ending of peripheral vasculature with peripheral non-perfusion; in group 3, there was a curving route of peripheral vasculature forming vascular arcades or anastomosis; and in group 4, the same as in group 3, but with one or more wedge-shaped avascular notches. Comparisons of age, sex, AXL, and RF, association of breaks with lattice degeneration and retinal non-perfusion, surgical procedures utilized, and mean numbers of operations were made among the four groups. Of the 73 eyes studied, there were 13 eyes (17.8% in group 1, 3 eyes (4.1% in group 2, 40 eyes (54.8% in group 3 and 17 eyes (23.3% in group 4. Significant differences in age, AXL and RF, and association of retinal breaks to non-perfusion were noted among the four groups. Patients in group 1 had older ages, while younger ages were noted in groups 3 and 4. Eyes in group 1 had the shortest average AXL and were least myopic in contrast to the eyes in groups 3 and 4. Association of retinal breaks and retinal non-perfusion was significantly higher in groups 2, 3 and 4 than in group 1. In conclusion, peripheral vascular anomalies are common in cases with RRD. Patients with peripheral non-perfusion tend to be younger, with longer axial length and have the breaks associated with retinal non-perfusion.

A study was conducted to evaluate the effects of different concentrations of lead (Pb) and cadmium (Cd) applied as their nitrates on soil microbial biomass carbon (C(mic)) and nitrogen (N(mic)), and substrate utilization pattern of soil microbial communities. The C(mic) and N(mic) contents were determined at 0, 14, 28, 42 and 56 days after heavy metal application (DAA). The results showed a significant decline in the C(mic) for all Pb and Cd amended soils from the start to 28 DAA. From 28 to 56 DAA, C(mic) contents changed non-significantly for all other treatments except for 600 mgkg(-1) Pb and 100 mgkg(-1) Cd in which it declined significantly from 42 to 56 DAA. The N(mic) contents also decreased significantly from start to 28 DAA for all other Pb and Cd treatments except for 200 mgkg(-1) Pb which did not show significant difference from the control. Control and 200 mgkg(-1) Pb had significantly lower soil microbial biomass C:N ratio as compared with other Pb treatments from 14 to 42 DAA, however at 56 DAA, only 1000 mgkg(-1) Pb showed significantly higher C:N ratio compared with other treatments. No significant difference in C:N ratio for all Cd treated soils was seen from start to 28 DAA, however from 42 to 56 DAA, 100 mgkg(-1) Pb showed significantly higher C:N ratio compared with other treatments. On 56 DAA, substrate utilization pattern of soil microbial communities was determined by inoculating Biolog ECO plates. The results indicated that Pb and Cd addition inhibited the functional activity of soil microbial communities as indicated by the intensity of average well color development (AWCD) during 168 h of incubation. Multivariate analysis of sole carbon source utilization pattern demonstrated that higher levels of heavy metal application had significantly affected soil microbial community structure.

Caterinicchio, R P

1987-01-01

This article is the first of a two-part series which argues for the concurrent management of the appropriateness, necessity, and quality of patient care. Intensifying scrutiny by the credentialing groups, the PROs and all third-party payors underscores the vital need to implement cost-effective information systems which integrate the departmentalized functions of patient-physician profiling, DRG case-mix analyses, length of stay monitoring, pre-admission/admission and continued stay review, discharge planning, risk management, incident reporting and quality review. In the domain of physician performance regarding admitting and practice patterns, the ability to exercise concurrent utilization-quality review means early detection and prevention of events which would otherwise result in denials of payment and/or compromised patient care. Concurrent utilization-quality review must, by definition, be managerially invasive and focused; hence, it is integral to maintaining the integrity of the services and product lines offered by the provider. In fact, if PPO status is a marketing agenda, then the institutional objectives of cost-effectiveness, productivity, value, and competitiveness can only be achieved through concurrent utilization-quality review.

Each infectious agent represents a unique combination of pathogen-associated molecular patterns that interact with specific pattern-recognition receptors expressed on immune cells. Therefore, we surmised that the blood immune cells of individuals with different infections might bear discriminative transcriptional signatures. Gene expression profiles were obtained for 131 peripheral blood samples from pediatric patients with acute infections caused by influenza A virus, Gram-negative (Escherichia coli) or Gram-positive (Staphylococcus aureus and Streptococcus pneumoniae) bacteria. Thirty-five genes were identified that best discriminate patients with influenza A virus infection from patients with either E coli or S pneumoniae infection. These genes classified with 95% accuracy (35 of 37 samples) an independent set of patients with either influenza A, E coli, or S pneumoniae infection. A different signature discriminated patients with E coli versus S aureus infections with 85% accuracy (34 of 40). Furthermore, distinctive gene expression patterns were observed in patients presenting with respiratory infections of different etiologies. Thus, microarray analyses of patient peripheral blood leukocytes might assist in the differential diagnosis of infectious diseases. PMID:17105821

Yet, there remain few studies that focus on healthcare utilization and its relationship with comorbidities in these elderly mentally ill patients. Comparative study. Information on demographics, comorbidities, and healthcare utilization was taken from an electronic medical record system. Wishard Health Services senior care and community mental health clinics. Patients age 65 years and older-255 patients with serious mental illness (schizophrenia, major recurrent depression, and bipolar illness) attending a mental health clinic and a representative sample of 533 nondemented patients without serious mental illness attending primary care clinics. Patients having serious mental illness had significantly higher rates of medical emergency department visits (p = 0.0027) and significantly longer lengths of medical hospitalizations (p mentally ill group (p seriously mentally ill. The differences in healthcare utilization between the groups remained significant after adjusting for comorbidity levels, lifestyle factors, and attending primary care. Our findings of higher rates of emergency care, longer hospitalizations, and increased frequency of falls, substance abuse, and alcoholism suggest that seriously mentally ill older adults remain a vulnerable population requiring an integrated model of healthcare.

Objectives Sickle cell disease (SCD) is associated with high healthcare utilization rates and poor outcomes in a subset of patients, although the underlying factors that predict this phenotype are poorly understood. Prior studies suggest that comorbid avascular necrosis (AVN) contributes to high healthcare utilization. We sought to clarify whether AVN independently predicts acute care utilization in adults with SCD and to identify characteristics of those with AVN that predict higher utilization. Methods We reviewed the medical records of 87 patients with SCD with symptomatic AVN and compared acute care utilization and clinical characteristics with 87 sex- and age-matched patients with SCD without symptomatic AVN. Patients with ≥2 years of follow-up were included. Outcomes were compared using bivariate analysis and multivariate regression. Results Our study included 1381 follow-up years, with a median of 7 years per patient. The AVN cohort had greater median rates of urgent care visits (3.2/year vs 1.3/year; P = 0.0155), admissions (1.3/year vs 0.4/year; P = 0.0002), and admission days (5.1 days/year vs 1.8 days/year; P = 0.0007). History of high utilization (odds ratio [OR] 4.28; P = 0.001), acute chest syndrome (OR 3.12; P = 0.005), pneumonia (OR 3.20; P = 0.023), hydroxyurea therapy (OR 2.23; P = 0.0136), and long-term transfusion (OR 2.33; P = 0.014) were associated with AVN. In a median regression model, AVN, acute chest syndrome, and pneumonia were independently associated with greater urgent care visits and admissions. Conclusions Symptomatic AVN was found to be an independent risk factor for acute care utilization in patients with SCD. Because this is a potentially modifiable factor, further studies are urgently needed to determine whether AVN prevention/early treatment interventions will alter utilization and improve outcomes for patients with SCD.

To estimate the utilization patterns of cancer prevention programs in women during the period 2000-2012 in Mexican women who participated in three national surveys. We analyzed data from the ENSA 2000, ENSANUT 2006 and ENSANUT 2012 that are representative of the Mexican population. Prevalences were obtained, trend tests and Poisson regression were used to determine the possibility of having more coverage. The coverage of Papanicolaou use in the last 12 months in 2012 was 45.5%, HPV testing in the last four years was 11.9% and mammography use in the past two years was 29.4% and 17.2% in women aged 50-69 years and 40-49 years, respectively. Although there was an increase in the coverage of screening programs, there should be a boost in the service quality and universal coverage.

Full text: Background: Lymphoscintigraphy (LS) is the diagnostic test of choice differentiating lymphoedema from other causes of extremity swelling. The LS patterns in normal and congenital lymphoedema in the paediatric population are not well defined. The impact of LS on clinical decision making is also not well reported. Aims: 1. define normal LS patterns in the pediatric population 2. describe types of abnormality (aplasia, hypoplasia, hyperplasia/dilated system) 3. describe LS patterns in syndromic lymphatic vascular disease 4. correlate LS with clinical impact on patient management. Methods: Retrospective review of all paediatric patients who had LS from July 1996-April 2008 was undertaken. Indications, sites of abnormality, LS patterns and clinical outcome were reviewed. Results: 118 patients (3mths-21yrs, mean 6 yrs) underwent LS. Normal LS patterns and variations were identified in 57 pts (48%). Sixty-one scans (52%) were abnormal showing lymph node aplasia (11%), hypoplasia (17%), mixed-pattern (8%), hyperplasia/dilated system (4%) and other patterns ie intestinal/pulmonary lymphangiectasia and vascual lymphatic malformations (11%). Patients with no signs of lymphoedema may still have aplasia or hypoplasia on LS. Dermal back flow is not always seen in lymphoedema. Management impact related to diagnosis and potential for development of lymphoedema in other limbs, differentiation of lymphoedema in patients with other vascular anomalies, stratification for lymphoedema therapy or referral to the dysmorphology clinic. Conclusion: LS is a valuable tool in the evaluation of lymphoedema in pediatric patients. Recognition of scan patterns in patients with suspected lymphoedema or lymphatic vascular diseases is essential as it plays a major role in the clinical management.

Immunotherapy combined with surgery is associated with better survival than surgery alone in patients with advanced melanoma. This study examined the utilization of immunotherapy in relation to population characteristics and the associated survival benefit. This was a retrospective cohort study utilizing the US National Cancer Database. The study population included 6,165 adult patients (≥18 years) with stage III cutaneous melanoma (median follow-up=32 months). A total of 1,854 patients underwent immunotherapy in addition to surgery, which was associated with a survival benefit over surgery alone (hazard ratio(HR)=0.66, 95% confidence interval(CI)=0.56-0.77, pimmunotherapy utilization (all pimmunotherapy usage was found (p=0.07). Compared to other demographic factors, insurance status was associated with the greatest disparities in immunotherapy utilization and mortality for patients who underwent surgery for advanced melanoma.

Objective: To determine the patterns of peritoneal involvement in patients with abdominopelvic malignancies. Study Design:Retrospective observational study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from May 2004 to May 2012. Methodology: Two hundred and three patients with histopathologically proven abdominopelvic malignancies with peritoneal involvement who underwent contrast-enhanced CT abdomen and pelvis were identified through electronic data base system and were included in this study after ethical committee approval. Peritoneal disease pattern, predominant sites of involvement and associated findings of ascites, lymph nodes and metastasis were assessed. Patients with tuberculosis and lymphoproliferative disorders were excluded. Results: The malignancies showing peritoneal involvement, in decreasing order of frequency, were ovarian cancer (n=118), colorectal cancer (n=45), pancreatic cancer (n=11), gastric cancer (n=7), endometrial cancer (n=6), gallbladder/ challenge-carcinoma and hepatocellular cancer (n=5 each), cervical cancer (n=3), renal cell carcinoma (n=2) and transitional cell urinary bladder cancer (n=1). The most common pattern of peritoneal involvement was mixed in 79 patients (39 percentage), omental caking in 74 patients (37 percentage) and nodular deposits in 50 patients (24 percentage). The most common sites of peritoneal involvement were pelvic peritoneum followed by greater omentum. Conclusion: Peritoneal involvement is the commonest with ovarian and colorectal carcinoma. Mixed pattern of peritoneal disease was most frequently seen in these patients followed by omental caking and nodular peritoneal deposits. (author)

We propose a method for transfer-printed electrode patterns onto flexible/plastic substrates, specifically intended for metal ink that requires a high sintering temperature. Typically, metal-ink-based electrodes cannot be picked up for microtransfer printing because the adhesion between the electrodes and the donor substrate greatly increases after the sintering process due to the binding materials. We introduced a polymeric donor layer between the printed electrodes and the donor substrate and effectively reduced the adhesion between the Ag pattern and the polymeric donor layer by controlling the interfacial contact area. After completing a wet-etching process for the polymeric donor layer, we obtained Ag patterns supported on the fine polymeric anchor structures; the Ag patterns could be picked up onto the stamp surface even after the sintering process by utilizing the viscoelastic properties of the elastomeric stamp with a pick-up velocity control. The proposed method enables highly conductive metal-ink-based electrode patterns to be applied on thermally weak plastic substrates via an all-solution process. Metal electrodes transferred onto a film showed superior electrical and mechanical stability under the bending stress test required for use in printed flexible electronics. (paper)

Purpose: To describe the patterns of definitive radiotherapy practice for patients with uterine cervical cancer from 1999 to 2001 in Japan. Methods and Materials: The Japanese Patterns of Care Study (JPCS) working group conducted a third extramural audit survey of 68 institutions and collected specific information on 324 cervical cancer patients treated with definitive radiotherapy. Results: Almost all patients (96%) were treated with whole pelvic radiotherapy using opposing anteroposterior fields (87%). A midline block was used in 70% of the patients. Intracavitary brachytherapy (ICBT) was applied in 82% of cases. Most patients (89%) were treated with high-dose rate (HDR) ICBT. Calculation of doses to organs at risk (ICRU 38) was performed for rectum in 25% of cases and for bladder in 18% of cases. Only 3% of patients were given intravenous conscious sedation during ICBT applicator insertions. The median total biologically effective dose at point A (EBRT+ICBT) was 74 Gy 10 in cases treated with HDR-ICBT. There was no significant difference in total biologically effective dose between stages. The median overall treatment time was 47 days. Concurrent chemoradiation was applied in 17% of patients. Conclusions: This study describes the general patterns of radiotherapy practice for uterine cervical cancer in Japan. Although methods of external radiotherapy seemed to be appropriate, there was room for improvement in ICBT practice, such as pretreatment. A substantial difference in total radiotherapy dose between Japan and the United States was observed

Regionalization of complex surgeries has increased patient travel distances possibly leaving a substantial burden on those at risk for poorer surgical outcomes. To date, little is known about travel patterns of cancer surgery patients in regionalized settings. To inform this issue, we sought to assess travel patterns of those undergoing a major cancer surgery within a regionalized system. We identified 4733 patients who underwent lung, esophageal, gastric, liver, pancreatic, and colorectal resections from 2002-2014 within a multihospital system in the Mid-Atlantic region of the United States. Patient age, race and/or ethnicity, and insurance status were extracted from electronic health records. We used Geographical Information System capabilities in R software to estimate travel distance and map patient addresses based on cancer surgery type and these characteristics. We used visual inspection, analysis of variance, and interaction analyses to assess the distribution of travel distances between patient populations. A total of 48.2% of patients were non-white, 49.9% were aged >65 y, and 54.9% had private insurance. Increased travel distance was associated with decreasing age and those undergoing pancreatic and esophageal resections. Also, black patients tend to travel shorter distances than other racial and/or ethnic groups. These maps offer a preliminary understanding into variations of geospatial travel patterns among patients receiving major cancer surgery in a Mid-Atlantic regionalized setting. Future research should focus on the impact of regionalization on timely delivery of surgical care and other quality metrics. Copyright © 2015 Elsevier Inc. All rights reserved.

Severe mental illness (SMI) and substance use disorders (SUD) are among the more chronic and costly mental health conditions treated in the Department of Veterans Affairs (VA). Service use patterns of returning veterans with SMI and SUD have received little attention. We examined gender differences in the utilization of VA services among a national sample of Operations Enduring Freedom, Iraqi Freedom, and New Dawn (OEF/OIF/OND) VA patients with SMI, SUD, and their comorbidity (SMI/SUD) in their first year of established VA care (N = 24,166). Outpatient services and acute-residential stays were modeled using negative binomial and logistic regression, respectively. Among all diagnostic categories, men used outpatient services less often than did women, including primary care (adjusted rate ratio [ARR] = .71, 95% confidence interval CI [.68, .74]), mental health (ARR = .85, 95% CI [.80, .91]), and addiction (ARR = .91, 95% CI [.83, .99]) services. For emergency department (ED) and psychiatric inpatient services, gender interacted significantly with diagnosis. The combination of SMI/SUD compared to either SMI or SUD conferred greater risk of ED utilization among men than women (adjusted odds ratio [AOR] = 2.09, 95% CI [1.24, 3.51], and 1.95, 95% CI [1.17, 3.26], respectively). SMI versus SUD conferred greater risk of psychiatric inpatient utilization among men than women (AOR = 1.83, 95% CI [1.43, 2.34]). Our findings point to gender differences in outpatient and acute service utilization among OEF/OIF/OND VA patients with some of the more chronic and costly mental health conditions. Further investigation of health care utilization patterns is needed to understand factors driving these gender differences to ensure that veterans have appropriate access to the services they need.

Full Text Available OBJECTIVE: To identiy left ventricular geometric patterns in hypertensive patients on echocardiography, and to correlate those patterns with casual blood pressure measurements and with the parameters obtained on a 24-hour ambulatory blood pressure monitoring. METHODS: We studied sixty hypertensive patients, grouped according to the Joint National Committee stages of hypertension.. Using the single- and two-dimensional Doppler Echocardiography, we analyzed the left ventricular mass and the geometric patterns through the correlation of left ventricular mass index and relative wall thickness. On ambulatory blood pressure monitoring we assessed the means and pressure loads in the different geometric patterns detected on echocardiography RESULTS: We identified three left ventricular geometric patterns: 1 concentric hypertrophy, in 25% of the patients; 2 concentric remodeling, in 25%; and 3 normal geometry, in 50%. Casual systolic blood pressure was higher in the group with concentric hypertrophy than in the other groups (p=0.001. Mean systolic pressure in the 24h, daytime and nighttime periods was also higher in patients with concentric hypertrophy, as compared to the other groups (p=0.003, p=0.004 and p=0.007. Daytime systolic load and nighttime diastolic load were higher in patients with concentric hypertrophy ( p=0.004 and p=0.01, respectively. CONCLUSIONS: Left ventricular geometric patterns show significant correlation with casual systolic blood pressure, and with means and pressure loads on ambulatory blood pressure monitoring.

Occupational injuries constitute a global health challenge, yet they receive comparatively modest scientific attention. Pattern of occupational injuries and its safety precautions among wagon repair workers is an important health issue, especially in developing countries like India. To assess the pattern of occupational injuries and utilization of safety measures among railway wagon repair workshop workers in Jhansi (U.P.). Railway wagon repair workshop urban area, Jhansi (U.P). Occupation-based cross-sectional study. A cross-sectional study was conducted among 309 workers of railway workshop in Jhansi (U.P.) who were all injured during the study period of 1 year from July 2015 to June 2016. Baseline characteristics, pattern of occupational injuries, safety measures, and their availability to and utilization by the participants were assessed using a pretested structured questionnaire. Data obtained were collected and analyzed statistically by simple proportions and Chi-square test. The majority of studied workers aged between 38 and 47 years ( n = 93, 30.6%) followed by 28-37 years ( n = 79, 26%). Among the pattern of occupational injuries, laceration (28.7%) was most common followed by abrasion/scratch (21%). Safety shoes and hat were utilized 100% by all workers. Many of them had more than 5 years of experience ( n = 237, 78%). Age group, education level, and utilization of safety measures were significantly associated with pattern of occupational injuries in univariate analysis ( P safety measures is low among workers on railway wagon repair workshop, which highlights the importance of strengthening safety regulatory services toward this group of workers. Younger age group workers show a significant association with open wounds and surface wounds. As the education level of workers increases, the incidence of injuries decreases. Apart from shoes, hat, and gloves, regular utilization of other personal protective equipment was not seen.

The primary purposes of this study were to (1) compare the characteristics of childhood experiences of parental rearing patterns in China reported by patients with borderline personality disorder (BPD), patients with other personality disorders and patients without personality disorders; (2) identify the reported parental rearing patterns associated with BPD in China; and (3) determine whether these patterns differ for males and females. One hundred and fifty-two patients with BPD, 79 patients with other personality disorders and 55 patients without Axis II diagnoses were administered the Chinese version of the McLean Screening Instrument for BPD and completed the Egna Minnen av Barndoms Uppfostran (EMBU), a self-report measure of childhood parental rearing patterns. Parental rearing patterns reported by the BPD group were characterized by less emotional warmth, and greater punishment, rejection and control than patterns reported by the other two groups. Within the BPD group, males were more likely than females to report parental punishment, rejection and control. Paternal punishment, low maternal emotional warmth and female gender predicted BPD diagnosis. Negative parental rearing patterns appear to contribute to the development of BPD in China and vary with the gender of the child. Maternal emotional warmth may be a protective factor against BPD. © 2013 International Union of Psychological Science.

Current guidelines recommend triple antithrombotic therapy (TAT), defined as acetylsalicylic acid (ASA), clopidogrel, and warfarin, for patients with nonvalvular atrial fibrillation who have undergone percutaneous coronary intervention with stent implantation. The choice of anticoagulant/antiplatelet therapy in this population is ambiguous and complex, and prescribing patterns are not well documented. To characterize local prescribing patterns for anticoagulant/antiplatelet therapy after percutaneous coronary intervention in patients with nonvalvular atrial fibrillation. A chart review was conducted at a single quaternary cardiology centre. Patients with nonvalvular atrial fibrillation were identified via medical records, and those who underwent percutaneous coronary intervention were identified using a local clinical patient registry. Adult inpatients with nonvalvular atrial fibrillation and a CHADS2 score (based on congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, prior stroke) of 1 or higher who underwent percutaneous coronary intervention from 2011 to 2013 were included. Patients undergoing cardiovascular surgery or transcatheter aortic valve replacement, those with mechanical devices requiring anticoagulation, and those with an allergy to any component of TAT were excluded. Seventy patients were included. The median age was 75 years, and 52 (74%) were men. At discharge, 30 (43%) were receiving TAT and 27 (39%) were receiving dual antiplatelet therapy (clopidogrel and ASA). No patients received the combination of warfarin and clopidogrel. Among those who received TAT, 90% (19 of 21) who received a bare metal stent had a recommended duration of 1 month, and 75% (6 of 8) who received a drug-eluting stent had a recommended duration of 1 year. Direct-acting oral anticoagulants with 2 antiplatelet drugs were prescribed for 9% (6 of 70) of the patients, and 10% (7 of 70) received ticagrelor and ASA with or without warfarin. Overall, the

To evaluate health care utilization, treatment patterns and costs among patients with mycosis fungoides-cutaneous T-cell lymphoma (MF-CTCL). This retrospective cohort study queried the HealthCore Integrated Research Database to identify patients ≥18 years with ≥2 diagnoses of MF-CTCL (ICD-9-CM code 202.1x, 202.2x) between 07 January 2006 and 07 January 2013. Index date was defined as first MF-CTCL diagnosis. Patients were continuously enrolled ≥6 months before and ≥12 months after index date. Severe MF-CTCL was identified via systemic therapy use postindex. Generalized linear model (GLM) was used to estimate the relationship between MF-CTCL severity and healthcare costs controlling for selected factors. A total of 1981 MF-CTCL patients were evaluated: 493 (24.9%) severe and 1488 (75.1%) with mild to moderate disease. GLM analysis indicated severe MF-CTCL patients incurred higher all-cause healthcare total costs compared to patients with mild-to-moderate MF-CTCL (coefficient estimate: 4.19, p < .0001). About 51% of patients did not receive any MF-CTCL-specific treatment within 60 days after MF-CTCL diagnosis. MF-CTCL severity was associated with greater healthcare resource utilization and costs. These findings suggest that about half of MF-CTCL patients do not receive MF-CTCL-specific treatment within 60 days following initial diagnosis. Future studies are needed to understand reasons for delayed treatment initiation.

Although 30-50% of constipated patients exhibit dyssynergia, an optimal method of diagnosis is unclear. Recently, consensus criteria have been proposed but their utility is unknown. To examine the diagnostic yield of colorectal tests, reproducibility of manometry and utility of Rome II criteria. A total of 100 patients with difficult defecation were prospectively evaluated with anorectal manometry, balloon expulsion, colonic transit and defecography. Fifty-three patients had repeat manometry. During attempted defecation, 30 showed normal and 70 one of three abnormal manometric patterns. Forty-six patients fulfilled Rome criteria and showed paradoxical anal contraction (type I) or impaired anal relaxation (type III) with adequate propulsion. However, 24 (34%) showed impaired propulsion (type II). Forty-five (64%) had slow transit, 42 (60%) impaired balloon expulsion and 26 (37%) abnormal defecography. Defecography provided no additional discriminant utility. Evidence of dyssynergia was reproducible in 51 of 53 patients. Symptoms alone could not differentiate dyssynergic subtypes or patients. Dyssynergic patients exhibited three patterns that were reproducible: paradoxical contraction, impaired propulsion and impaired relaxation. Although useful, Rome II criteria may be insufficient to identify or subclassify dyssynergic defecation. Symptoms together with abnormal manometry, abnormal balloon expulsion or colonic marker retention are necessary to optimally identify patients with difficult defecation.

Full Text Available Little is known about actual dietary patterns and their associations with clinical outcomes in hemodialysis patients. We identified dietary patterns in hemodialysis patients in Japan and examined associations between dietary patterns and clinical outcomes.We used data from 3,080 general-population participants in the Hisayama study (year 2007, and data from 1,355 hemodialysis patients in the Japan Dialysis Outcomes and Practice Patterns Study (JDOPPS: years 2005-2007. Food intake was measured using a brief self-administered diet-history questionnaire (BDHQ. To identify food groups with the Hisayama population data, we used principal components analysis with Promax rotation. We adjusted the resulting food groups for total daily energy intake, and then we used those adjusted food-group scores to identify dietary patterns in the JDOPPS patients by cluster analysis (Ward's method. We then used Cox regression to examine the association between dietary patterns and a composite of adverse clinical outcomes: hospitalization due to cardiovascular disease or death due to any cause.We identified three food groups: meat, fish, and vegetables. Using those groups we then identified three dietary patterns: well-balanced, unbalanced, and other. After adjusting for potential confounders, we found an association between an unbalanced diet and important clinical events (hazard ratio 1.90, 95% C.I. 1.19-3.04.Hemodialysis patients whose diet was unbalanced were more likely to have adverse clinical outcomes. Thus hemodialysis patients might benefit not only from portion control, but also from a diet that is well-balanced diet with regard to the food groups identified here as meat, fish, and vegetables.

Full Text Available Abstract Background Several instruments and clinical scoring systems have been established to evaluate patients with ligamentous knee injuries. A comparison of individual articles in the literature is challenging, not only because of heterogeneity in methodology, but also due to the variety of the scoring systems used to document clinical outcomes. There is limited information about the correlation between used scores and quality of life with no information being available on the impact of each score on the utility values. The aim of this study was to compare the most commonly used scores for evaluating patients with anterior cruciate ligament (ACL injuries, and to establish corresponding utility values. These values will be used for the interpretation and comparison of outcome results in the currently available literature for different treatment options. Methods Four hypothetical vignettes were defined, based on different levels of activities after rupture of the ACL to simulate typical situations seen in daily practice. A questionnaire, including the Health Utility Index (HUI for utility values, the IKDC subjective score, the Lysholm and the Tegner score, was created and 25 orthopedic surgeons were asked to fill the questionnaire for each hypothetical patient as proxies for all patients they had treated and who would fit in that hypothetical vignette. Results The utility value as an indicator for quality of life increased with the level of activity. Having discomforts already during normal activities of daily living was rated with a mean utility value of 0.37 ± 0.19, half of that of a situation where mild sport activity was possible without discomfort (0.78 ± 0.11. All investigated scores were able to distinguish clearly (p Conclusions Here we report the correlation between the most commonly used scores for the assessment of patients with a ruptured ACL and utility values as an indicator of quality of life.

In its fee-for-service funding model for primary care, British Columbia, Canada, introduced incentive payments to general practitioners as pay for performance for providing enhanced, guidelines-based care to patients with chronic conditions. Evaluation of the program was conducted at the health care system level. To examine the impact of the incentive payments on annual health care costs and hospital utilization patterns in British Columbia. The study used Ministry of Health administrative data for Fiscal Year 2010-2011 for patients with diabetes, congestive heart failure, chronic obstructive pulmonary disease, and/or hypertension. In each disease group, cost and utilization were compared across patients who did, and did not, receive incentive-based care. Health care costs (eg, primary care, hospital) and utilization measures (eg, hospital days, readmissions). After controlling for patients' age, sex, service needs level, and continuity of care (defined as attachment to a general practice), the incentives reduced the net annual health care costs, in Canadian dollars, for patients with hypertension (by approximately Can$308 per patient), chronic obstructive pulmonary disease (by Can$496), and congestive heart failure (by Can$96), but not diabetes (incentives cost about Can$148 more per patient). The incentives were also associated with fewer hospital days, fewer admissions and readmissions, and shorter lengths of hospital stays for all 4 groups. Although the available literature on pay for performance shows mixed results, we showed that the funding model used in British Columbia using incentive payments for primary care might reduce health care costs and hospital utilization.

A proposed benefit of expanding Medicaid eligibility under the Patient Protection and Affordable Care Act (ACA) was a reduction in emergency department (ED) utilization for primary care needs. Pre-ACA studies found that new Medicaid enrollees increased their ED utilization rates, but the effect on system-level ED visits was less clear. Our objective was to estimate the effect of Medicaid expansion on aggregate and individual-based ED utilization patterns within Maryland. We performed a retrospective cross-sectional study of ED utilization patterns across Maryland, using data from Maryland's Health Services Cost Review Commission. We also analyzed utilization differences between pre-ACA (July 2012 to December 2013) uninsured patients who returned post-ACA (July 2014 to December 2015). The total number of ED visits in Maryland decreased by 36,531 (-1.2%) between the 6 quarters pre-ACA and the 6 quarters post-ACA. Medicaid-covered ED visits increased from 23.3% to 28.9% (159,004 additional visits), whereas uninsured patient visits decreased from 16.3% to 10.4% (181,607 fewer visits). Coverage by other insurance types remained largely stable between periods. We found no significant relationship between Medicaid expansion and changes in ED volume by hospital. For patients uninsured pre-ACA who returned post-ACA, the adjusted visits per person during 6 quarters was 2.38 (95% confidence interval 2.35 to 2.40) for those newly enrolled in Medicaid post-ACA compared with 1.66 (95% confidence interval 1.64 to 1.68) for those remaining uninsured. There was a substantial increase in patients covered by Medicaid in the post-ACA period, but this did not significantly affect total ED volume. Returning patients newly enrolled in Medicaid visited the ED more than their uninsured counterparts; however, this cohort accounted for only a small percentage of total ED visits in Maryland.

2013-01-01

Full Text Available In China's healthcare reform, community health centers (CHCs are designed to take a pivotal role in providing primary care. Whilst about 20% of all outpatient care in China is delivered by the traditional Chinese medicine (TCM sector, hospitals, instead of CHCs, are major providers. Using current patterns of patient utilization this study aims to inform CHCs on how they may strengthen access to TCM services. Three thousand three hundred and sixty CHC patients from six cities within the urban Pearl Delta Region were enumerated using multistage cluster sampling. Fifty-two percent had visited herbalists within three months with a mean visit frequency of 1.50 times. Herbal treatments, which are cheaper than western medicines, were more popular amongst those who needed to pay out of pocket including the uninsured. Herbal medicines appeared to be an alternative for those who are underinsured. Acupuncturists and massage therapists were visited by smaller proportions, 6.58% and 5.98%, respectively, with a mean three-month visit of 0.27 and 0.26 times. Access was restricted by lack of social insurance coverage. Whilst increasing provision of TCM in CHCs might respond to patient demand, increasing insurance coverage for TCM needs to be evaluated using current evidence on safety and effectiveness.

Background. Pattern differentiation is the foundation of traditional Chinese medicine (TCM) treatment for erectile dysfunction (ED). This study aims to investigate the differences in cerebral activity in ED patients with different TCM patterns. Methods. 27 psychogenic ED patients and 27 healthy subjects (HS) were enrolled in this study. Each participant underwent an fMRI scan in resting state. The fractional amplitude of low-frequency fluctuation (fALFF) was used to detect the brain activity changes in ED patients with different patterns. Results. Compared to HS, ED patients showed an increased cerebral activity in bilateral cerebellum, insula, globus pallidus, parahippocampal gyrus, orbitofrontal cortex (OFC), and middle cingulate cortex (MCC). Compared to the patients with liver-qi stagnation and spleen deficiency pattern (LSSDP), the patients with kidney-yang deficiency pattern (KDP) showed an increased activity in bilateral brainstem, cerebellum, hippocampus, and the right insula, thalamus, MCC, and a decreased activity in bilateral putamen, medial frontal gyrus, temporal pole, and the right caudate nucleus, OFC, anterior cingulate cortex, and posterior cingulate cortex (P emotion-related regions, including prefrontal cortex and cingulated cortex.

A subpopulation of sickle-cell disease patients, termed super-utilizers, presents frequently to emergency departments (EDs) for vaso-occlusive events and may consume disproportionate resources without broader health benefit. To address the healthcare needs of this vulnerable patient population, we piloted a multidisciplinary intervention seeking to create and use individualized patient care plans that alter utilization through coordinated care. Our goals were to assess feasibility primarily, and to assess resource use secondarily. We evaluated the effects of a single-site interventional study targeted at a population of adult sickle-cell disease super-utilizers using a pre- and post-implementation design. The pre-intervention period was 06/01/13 to 12/31/13 (seven months) and the post-intervention period was 01/01/14 to 02/28/15 (14 months). Our approach included patient-specific best practice advisories (BPA); an ED management protocol; and formation of a "medical home" for these patients. For 10 subjects targeted initially we developed and implemented coordinated care plans; after deployment, we observed a tendency toward reduction in ED and inpatient utilization across all measured indices. Between the annualized pre- and post-implementation periods we found the following: ED visits decreased by 16.5 visits/pt-yr (95% confidence interval [CI] [-1.32-34.2]); ED length of state (LOS) decreased by 115.3 hours/pt-yr (95% CI [-82.9-313.5]); in-patient admissions decreased by 4.20 admissions/pt-yr (95% CI [-1.73-10.1]); in-patient LOS decreased by 35.8 hours/pt-yr (95% CI [-74.9-146.7]); and visits where the patient left before treatment were reduced by an annualized total of 13.7 visits. We observed no patient mortality in our 10 subjects, and no patient required admission to the intensive care unit 72 hours following discharge. This effort suggests that a targeted approach is both feasible and potentially effective, laying a foundation for broader study.

Recent progress with spinal cord injured (SCI) patients indicates that with training they can recover some locomotor ability. Here we addressed the question of whether locomotor responses developed with training depend on re-activation of the normal motor patterns or whether they depend on learning new motor patterns. To this end we recorded detailed kinematic and EMG data in SCI patients trained to step on a treadmill with body-weight support (BWST), and in healthy subjects. We found that all patients could be trained to step with BWST in the laboratory conditions, but they used new coordinative strategies. Patients with more severe lesions used their arms and body to assist the leg movements via the biomechanical coupling of limb and body segments. In all patients, the phase-relationship of the angular motion of the different lower limb segments was very different from the control, as was the pattern of activity of most recorded muscles. Surprisingly, however, the new motor strategies were quite effective in generating foot motion that closely matched the normal in the laboratory conditions. With training, foot motion recovered the shape, the step-by-step reproducibility, and the two-thirds power relationship between curvature and velocity that characterize normal gait. We mapped the recorded patterns of muscle activity onto the approximate rostrocaudal location of motor neuron pools in the human spinal cord. The reconstructed spatiotemporal maps of motor neuron activity in SCI patients were quite different from those of healthy subjects. At the end of training, the locomotor network reorganized at both supralesional and sublesional levels, from the cervical to the sacral cord segments. We conclude that locomotor responses in SCI patients may not be subserved by changes localized to limited regions of the spinal cord, but may depend on a plastic redistribution of activity across most of the rostrocaudal extent of the spinal cord.

The objective of this study was to evaluate the patterns of pretreatment diagnostic assessment in uterine cervical cancer patients treated with definitive radiotherapy in Japan. The Japanese Patterns of Care Study working group conducted a second extramural audit survey of 68 institutions and collected specific information on 631 patients with cervical cancer. All patients were treated with radiotherapy in 1999-2001. Of these, 324 patients treated without surgery were the subjects of this study. International Federation of Gynecology and Obstetrics-prescribed diagnostic procedures were performed at moderate rates in our study cohort. The performance rates of chest X-ray, intravenous urography, cystoscopy, and proctoscopy were 74, 54, 53, and 33%, respectively. Cross sectional imaging studies were frequently performed. Pelvic CT, abdominal CT, and pelvic MRI were performed in 88, 80, and 76%, respectively. Lymphangiography (1%) and surgical evaluation (1%) were rarely done. Only one patient underwent positron emission tomography (PET) scans in this survey period. This study demonstrated the patterns of pretreatment diagnostic assessment in cervical cancer patients treated with definitive radiotherapy in Japan. (author)

To evaluate the relationship between eating patterns and therapeutic target's achieving in patients with type 2 diabetes. In this cross-sectional study, patients underwent clinical, laboratory, and nutritional evaluations. Dietary intake was assessed by a quantitative food frequency questionnaire and eating patterns identified by cluster analysis. The therapeutic targets were as follows: blood pressure, fasting plasma glucose, 40 mg/dL for men and >50 mg/dL for women; LDL-cholesterol, studied. We identified two eating patterns: "unhealthy" (n = 100)-high consumption of refined carbohydrates, ultra-processed foods, sweets and desserts ( P fasting plasma glucose, HbA1c, and LDL-cholesterol than the unhealthy group. Poisson regression confirmed the association of healthy eating pattern with attaining the therapeutic target for fasting plasma glucose [PR, 1.59 (95% CI, 1.01 to 2.34); P = 0.018], HbA1c [PR, 2.09 (95% CI, 1.17 to 3.74); P = 0.013], and LDL-cholesterol [PR, 1.37 (95% CI, 1.01 to 1.86); P = 0.042]. A healthy eating pattern, including the frequent intake of whole carbohydrates, dairy, white meat, fish, fruits, and vegetables, is associated with reduced fasting plasma glucose, HbA1c, and LDL cholesterol levels in patients with type 2 diabetes.

Ranolazine is an antianginal agent that was approved in the EU in 2008 as an add-on therapy for symptomatic chronic angina pectoris treatment in patients who are inadequately controlled by, or are intolerant to, first-line antianginal therapies. These patients' quality of life is significantly affected by more frequent angina events, which increase the risk of revascularization. To assess the cost-utility of ranolazine versus placebo as an add-on therapy for the symptomatic treatment of patients with chronic angina pectoris in Spain. A decision tree model with 1-year time horizon was designed. Transition probabilities and utility values for different angina frequencies were obtained from the literature. Costs were obtained from Spanish official DRGs for patients with chronic angina pectoris. We calculated the incremental cost-utility ratio of using ranolazine compared with a placebo. Sensitivity analyses, by means of Monte Carlo simulations, were performed. Acceptability curves and expected value of perfect information were calculated. The incremental cost-utility ratio was €8,455 per quality-adjusted life-year (QALY) per patient in Spain. Sensitivity analyses showed that if the decision makers' willingness to pay is €15,000 per QALY, the treatment with ranolazine will be cost effective at a 95 % level of confidence. The incremental cost-utility ratio is particularly sensitive to changes in utility values of those non-hospitalized patients with mild or moderate angina frequency. Ranolazine is a highly efficient add-on therapy for the symptomatic treatment of chronic angina pectoris in patients who are inadequately controlled by, or intolerant to, first-line antianginal therapies in Spain.

Objective We sought to describe meal and snack frequencies of individuals with recurrent binge eating and examine the association between these eating patterns and clinical correlates. Method Data from 106 women with a minimum diagnosis of recurrent binge eating were utilized. Meal and snack frequencies were correlated with measures of weight, eating disorder features, and depression. Participants who ate breakfast every day (n=25) were compared with those who did not (n=81) on the same measures. Results Breakfast was the least, and dinner the most, commonly consumed meal. Evening snacking was the most common snacking occasion. Meal patterns were not significantly associated with clinical correlates; however, evening snacking was associated with binge eating. Discussion Our findings largely replicated those reported in earlier research. More research is needed to determine the role of breakfast consumption in binge eating. PMID:21661003

To assess level of awareness and pattern of utilizing family planning services among women (15-49 years) of reproductive age at Urban Health Center, Azizabad Sukkur, Sindh. A cross-sectional study was conducted from April to June 2005 at Urban Health Care Center Azizabad Sukkur. Two hundred women of reproductive age group were interviewed by using a pre tested semi structured questionnaire visiting the health care center during the study period. Information was obtained after taking informed consent regarding socio demographic characteristics, knowledge, attitude and pattern of utilizing family planning services. The data was entered and analyzed by using statistical package SPSS version 13. About 75% of women and 42.5% husbands were found illiterate, 85% women were housewives, 69.5% were married before 18 years of age and 54% had nuclear family. Regarding desired number of children women responded one child (3%), 2-3 children (11%), 4-5 (37.5%), more than five children (36%), 5.5% said that children are God gifted and 7% did not answer. About 60% of women reported use of at least one contraceptive method and 40% had never used any contraceptive method. The women who received counseling from the health care provider were 48.5% and only 6% received information through media. Religious prohibition, shortage of female staff and cost of family planning contraceptive methods were the main reasons identified for not utilizing contraceptive methods. The unsatisfactory variables were long waiting hours at the center, non-availability of contraceptive, shortage of the female staff and cost. Limited number of women was aware and practice contraception in the area and utilization of family planning services were low. The efforts should be made for providing information to couple and improving quality of family planning services in the area. (author)

We sought to evaluate the association between constipation severity, productivity losses and healthcare utilization in a national sample of Italian patients with chronic non-organic constipation (CC). We enrolled 878 outpatients with CC. Clinical and demographic data were collected by physicians during clinical examinations. Patients completed a self-administered questionnaire (Patient Assessment of Constipation-Symptoms, PAC-SYM; Work Productivity and Activity Impairment; healthcare utilization, and Symptoms Checklist 90 Revised - Somatization Scale, SCL-90 R). Mean PAC-SYM score was 1.62 ± 0.69. Mean weekly sick time due to constipation was 2.7 ± 8.6 h and productivity losses due to presenteeism was 19.7% ± 22.3%. Adjusted productivity losses in patients with severe CC (PAC-SYM score 2.3-4.0) compared to patients with mild symptoms (PAC-SYM score 0.0-1.0) was Italian Purchase Power Parity US$ 6160. Constipation severity (PAC-SYM quintiles) was associated with higher healthcare utilization (RRPAC-SYM 4/01.84; p-value for linear trend <0.01). After adjustment for somatization scores, the association of constipation severity with productivity losses and healthcare utilization rates was attenuated yet statistically significant. We observed a graded increase in productivity losses and healthcare utilization with increasing constipation severity. Further studies should evaluate whether significant savings might be achieved with regimens aimed at reducing the constipation severity.

Full Text Available The clinical status of older individuals with multimorbidity can be further complicated by concomitant geriatric syndromes. This study explores multimorbidity patterns, encompassing both chronic diseases and geriatric syndromes, in geriatric patients attended in an acute hospital setting.Retrospective observational study.Unit of Social and Clinical Assessment (UVSS, Miguel Servet University Hospital (HUMS, Zaragoza (Spain. Year, 2011.A total of 924 hospitalized patients aged 65 years or older.Data on patients' clinical, functional, cognitive and social statuses were gathered through comprehensive geriatric assessments. To identify diseases and/or geriatric syndromes that cluster into patterns, an exploratory factor analysis was applied, stratifying by sex. The factors can be interpreted as multimorbidity patterns, i.e., diseases non-randomly associated with each other within the study population. The resulting patterns were clinically assessed by several physicians.The mean age of the study population was 82.1 years (SD 7.2. Multimorbidity burden was lower in men under 80 years, but increased in those over 80. Immobility, urinary incontinence, hypertension, falls, dementia, cognitive decline, diabetes and arrhythmia were among the 10 most frequent health problems in both sexes, with prevalence rates above 20%. Four multimorbidity patterns were identified that were present in both sexes: Cardiovascular, Induced Dependency, Falls and Osteoarticular. The number of conditions comprising these patterns was similar in men and women.The existence of specific multimorbidity patterns in geriatric patients, such as the Induced Dependency and Falls patterns, may facilitate the early detection of vulnerability to stressors, thus helping to avoid negative health outcomes such as functional disability.

About half of patients with acute liver failure (ALF) show clinical signs of cerebral edema and intracranial hypertension. Neuroimaging diagnostics and electroencephalography have poor correlation with intracranial pressure measurement. The objective of this study was to characterize the cerebral hemodynamics patterns with transcranial Doppler (TCD) sonography in patients with ALF. We studied 21 patients diagnosed with ALF, admitted to the intensive care unit (ICU) at the Centro de Investigaciones Médico Quirúrgicas of Cuba. All of these patients had a TCD performed on arrival at ICU, evaluating the following: systolic (SV), diastolic (DV), and medium (MV) flows velocities and pulsatility index (PI) in right middle cerebral artery (RMCA) via temporal windows. The sonographic patterns of cerebral hemodynamics were as follows: low-flow, 12 patients (57.1%); high resistance, 5 patients (23.8%); and hyperemic, 4 patients (19%). Patients who died while waiting had lower MV RMCA (56.1 vs 58.1 cm/s) and higher PI (1.71 vs 1.41) than patients who could undergo transplantation (P = .800 and P = .787, respectively). In patients diagnosed with ALF admitted to the ICU the predominating cerebral hemodynamic pattern was low-flow with resistance increase. The TCD was shown to be a useful tool in the initial evaluation for prognosis and treatment. Copyright © 2015 Elsevier Inc. All rights reserved.

Attention-deficit/hyperactivity disorder (ADHD) imposes a substantial burden on patients and their families. A retrospective, propensity score-matched cohort study compared treatment patterns, healthcare resource utilization (HRU) and costs among children/adolescents with ADHD aged 6-17 years at treatment initiation (index) in Germany who received atomoxetine (ATX) or long-acting methylphenidate (LA-MPH) monotherapy. Patients received at least one prescription for their index medication (ATX/LA-MPH) during 2006-2010; the first prescription marked the index date. ATX- and LA-MPH-indexed cohorts were matched 1:1 (n = 737); a patient subset was identified that had not received ADHD-indicated medications in 12 months prior to index (novel initiators: ATX, n = 486; LA-MPH, n = 488). Treatment patterns were evaluated among novel initiators, and HRU and costs among the matched cohorts in the 12 months after index. No significant differences in baseline characteristics were found between the novel initiator patient subsets. ATX-indexed novel initiators had significantly longer persistence to index medication [mean (standard deviation; SD) days: 222.0 (133.9) vs 203.2 (135.0), P = 0.029) but higher switching rates (8.8 vs 5.5 %, P = 0.045) than LA-MPH-indexed novel initiators. The total ATX-indexed cohort required more prescriptions [any medication; mean (SD): 20.9 (11.5) vs 15.7 (9.0), P < 0.001] and outpatient visits [mean (SD): 10.1 (6.3) vs 8.3 (5.3), P < 0.001], and incurred significantly higher total median healthcare costs (€1144 vs €541, P < 0.001) versus matched LA-MPH patients. These real-world data indicate that, among children/adolescents with ADHD in Germany, ATX-indexed patients may require more prescriptions and physician visits, and incur higher total healthcare costs, than matched LA-MPH patients.

Full Text Available Abstract Background Prader-Willi (PWS and Down Syndrome (DS are two genetic disorders characterised by some common clinical and functional features. A quantitative description and comparison of their patterns would contribute to a deeper understanding of the determinants of motor disability in these two syndromes. The aim of this study was to measure gait pattern in PWS and DS in order to provide data for developing evidence-based deficit-specific or common rehabilitation strategies. Methods 19 PWS patients (17.7-40 yr and 21 DS patients (18-39 yr were evaluated with an optoelectronic system and force platforms for measuring kinematic and kinetic parameters during walking. The results were compared with those obtained in a group of normal-weight controls (Control Group: CG; 33.4 + 9.6 yr. Results and Discussion The results show that PWS and DS are characterised by different gait strategies. Spatio-temporal parameters indicated a cautious, abnormal gait in both groups, but DS walked with a less stable strategy than PWS. As for kinematics, DS showed a significantly reduced hip and knee flexion, especially at initial contact and ankle range of motion than PWS. DS were characterised by lower ranges of motion (p Conclusions Our data show that DS walk with a less physiological gait pattern than PWS. Based on our results, PWS and DS patients need targeted rehabilitation and exercise prescription. Common to both groups is the aim to improve hypotonia, muscle strength and motor control during gait. In DS, improving pelvis and hip range of motion should represent a major specific goal to optimize gait pattern.

Low-dose weekly methotrexate (MTX) is the mainstay in the therapy of rheumatoid arthritis (RA). It can be given via oral, intramuscular or subcutaneous (SC) route. This study sought to determine the real-world pattern of treatment with SC MTX in Portuguese adult patients with active RA. Utilization of Metoject(®) in Rheumatoid Arthritis (UMAR) was a non-interventional, cohort multicenter study with retrospective data collection. Eligible patients had active RA, at least 18 years of age, and started SC MTX treatment in 2009 or 2010 after failure or intolerance to oral MTX. Data were collected from patient's clinical records. Both non-parametric and parametric survival methods were used to obtain a detailed understanding of SC MTX treatment duration. Fifty patients were included, of which only 9 discontinued SC MTX during the study follow-up period. The probability of discontinuation after 1, 2, and 3 years of treatment of SC MTX treatment is expected to be 6.10%, 8.50%, and 23.20%, respectively. The extrapolated median duration of SC MTX using an exponential model was 106.4 months/8.87 years. Mean dose of SC MTX was 18.36 mg. The reasons for treatment discontinuation were occurrence of adverse events in six patients and lack of efficacy in three. The long treatment duration of SC MTX highlights its excellent tolerability compared to oral MTX, especially concerning the frequent adverse gastrointestinal events of MTX. Furthermore, long MTX treatment duration provides the opportunity to postpone or even avoid expensive therapies with biologics. The results obtained from the UMAR study provide important information for the utilization and public financing of SC MTX in Portugal.

We assessed the utilization of antiepileptic drugs (AEDs), 1999-2005, in 4,798 prospective epilepsy pregnancies from 38 countries participating in EURAP, an international AED and pregnancy registry. Prominent differences in utilization patterns were observed across the various countries. Exposure...... to second-generation AEDs ranged from 3.5% in India and 7.3% in Italy to 75% in Denmark. Even wider variation was recorded in exposure to individual AEDs. The utilization of second-generation AEDs increased over time (for lamotrigine, from 9.9% of all pregnancies before 2001 to 29.6% after 2003......). The differences in use of individual AEDs across countries probably reflect lack of evidence concerning the optimal treatment of epilepsy in women of childbearing age, as well as variation in country-specific traditions, medication costs, and drug promotion. Our observations underscore the need for comparative...

To establish a baseline pattern of care across academic and community settings, it is important to examine the contemporary treatment of acromegaly. We characterized medical treatment patterns for acromegaly in the US to develop a basis for tracking concordance with guidelines. Acromegaly patients were identified in two commercial claims databases for this retrospective analysis. Study subjects had ≥2 medical claims with acromegaly (ICD-9-CM code 253.0) and ≥1 claim for pharmacotherapy (bromocriptine, cabergoline, octreotide SA, octreotide LAR, lanreotide, or pegvisomant) in the study timeframe (1 January 2002-31 December 2013). Patients were considered newly treated if they were continuously enrolled for ≥6 months before first observed treatment and had no claim for pharmacologic treatment during that time. Outcomes included various pharmacotherapies, including combination treatments, and differences between lines of therapy. A total of 3150 patients had ≥1 pharmacotherapy (mean age: 46.5 years; 50.1% were female); 1471 were newly treated. Somatostatin receptor ligands (SRLs) were the most common drug class used first line (57.2%); cabergoline (27.8%) was the most common treatment, followed by octreotide LAR (22.3%) and lanreotide (19.7%). SRLs were also the most commonly used second-line (42.8%) and third-line pharmacotherapies (43.9%), with combination therapy (23.2%) and octreotide LAR (19.8%) as the most commonly used treatments, respectively. This study, representing the largest claims-based analysis of acromegaly to date, used two databases across a 12 year period to examine complex treatment patterns in a difficult-to-study disease. Although wide variation in acromegaly treatment patterns exists in US clinical practice, in first-line, second-line, and third-line therapy, SRL was the most commonly used drug class. Drug combinations also varied considerably across lines of therapy. The switching between different monotherapies and varied use of drugs

Full Text Available Abstract Background This study measured how myelodysplastic syndrome (MDS patients value transfusion independence (TI, reduced transfusions (RT and transfusion-dependence (TD using health utility assessment methodology. Methods 47 MDS patients were interviewed, US (n = 8, France (n = 9, Germany (n = 9 and the UK (n = 21, to elicit the utility value of TI, RT and TD. Health states were developed based on literature; patient forum discussions; and were validated by a hematologist. Face-to-face interviews used the feeling thermometer Visual Analogue Scale (VAS and the Time Trade-Off (TTO method to value the health states on a 0 (dead to 1 (perfect health scale. Socio-demographic, clinical, and quality-of-life (EQ-5D characteristics were surveyed to describe the patient sample. Results and Discussion The mean age was 67 years (range: 29-83; 45% male, 70% retired; 40% had secondary/high school education, or higher (32%, and 79% lived with family, a partner or spouse, or friends. The mean time from MDS diagnosis was 5 years (range:1-23. Most patients (87% received previous transfusions and 49% had received a transfusion in the last 3 months. Mean EQ-5D index score was 0.78; patients reported at least some problem with mobility (45%, usual activities (40%, pain/discomfort (47%, and anxiety/depression (34%. Few patients had difficulty understanding the VAS (n = 3 and TTO (n = 4 exercises. Utility scores for TI were higher than for RT (0.84 vs. 0.77; p Conclusion Patients value TI, suggesting an important role for new treatments aiming to achieve greater TI in MDS. These results can be used in preference-based health economic evaluation of new MDS treatments, such as in future cost-utility studies.

Dry eye is a multifactorial, symptomatic disease associated with ocular surface inflammation and tear film hyperosmolarity. This study was designed to assess patterns of topical cyclosporine ophthalmic emulsion 0.05% (Restasis®) use in dry eye patients and determine if there were any differences in use based on whether dry eye is physician-coded as a primary or nonprimary diagnosis. Records for adult patients with a diagnosis of dry eye at an outpatient visit from January 1, 2008 to December 31, 2009 were selected from Truven Health MarketScan® Research Databases. The primary endpoint was percentage of patients with at least one primary versus no primary dry eye diagnosis who filled a topical cyclosporine prescription. Data analyzed included utilization of topical corticosteroids, oral tetracyclines, and punctal plugs. The analysis included 576,416 patients, accounting for 875,692 dry eye outpatient visits: 74.7% were female, 64.2% were ages 40-69 years, and 84.4% had at least one primary dry eye diagnosis. During 2008-2009, 15.9% of dry eye patients with a primary diagnosis versus 6.5% with no primary diagnosis filled at least one cyclosporine prescription. For patients who filled at least one prescription, the mean months' supply of cyclosporine filled over 12 months was 4.44. Overall, 33.9% of dry eye patients filled a prescription for topical cyclosporine, topical corticosteroid, or oral tetracycline over 2 years. Patients with a primary dry eye diagnosis were more likely to fill a topical cyclosporine prescription. Although inflammation is key to the pathophysiology of dry eye, most patients seeing a physician for dry eye may not receive anti-inflammatory therapies.

To determine the utility of cervical spine MRI in blunt trauma evaluation for instability after a negative non-contrast cervical spine CT. A review of medical records identified all adult patients with blunt trauma who underwent CT cervical spine followed by MRI within 48 h over a 33-month period. Utility of subsequent MRI was assessed in terms of findings and impact on outcome. A total of 1,271 patients with blunt cervical spine trauma underwent both cervical spine CT and MRI within 48 h; 1,080 patients were included in the study analysis. Sixty-six percent of patients with a CT cervical spine study had a negative study. Of these, the subsequent cervical spine MRI had positive findings in 20.9%; 92.6% had stable ligamentous or osseous injuries, 6.0% had unstable injuries and 1.3% had potentially unstable injuries. For unstable injury, the NPV for CT was 98.5%. In all 712 patients undergoing both CT and MRI, only 1.5% had unstable injuries, and only 0.42% had significant change in management. MRI for blunt trauma evaluation remains not infrequent at our institution. MRI may have utility only in certain patients with persistent abnormal neurological examination. • MRI has limited utility after negative cervical CT in blunt trauma. • MRI is frequently positive for non-specific soft-tissue injury. • Unstable injury missed on CT is infrequent.

Cognitive decline is common among older adults with cancer. The present study aimed to investigate the impact of cognitive decline on health utility value in older adults suffering from cancer. Consecutive patients aged 65 years or older with a primary diagnosis of malignant lymphoma or multiple myeloma were recruited. Patients were asked to complete the EuroQoL-5 (EQ-5D) scale to measure health utility and the Mini-Mental State Examination to assess cognitive decline. The potential impact of cognitive decline was investigated with univariate analysis. A multivariate regression analysis was conducted to control for potential confounding factors. Complete data were obtained from 87 patients, 29% of whom had cognitive decline. The mean ± SE EQ-5D score for patients with cognitive decline was significantly lower than that for those without cognitive decline (0.67 ± 0.04 vs 0.79 ± 0.03, t = 2.38, P = 0.02). However, multiple regression analysis showed that cognitive decline was not significantly associated with EQ-5D scores. Female sex and lower performance scores (worse physical condition) were significantly associated with EQ-5D scores. Cognitive decline may be involved in decreased health utility value in older adult patients with cancer. However, this effect does not seem to be independent, and the patient's physical condition may be a relevant confounding factor. © 2016 The Authors.

Background: Acute lymphoblastic leukemia (ALL) is a clonal malignant disorder characterized by an uncontrolled proliferation of immature T or B lymphocytes. Extensive studies have shown that the epigenetic changes, especially modified DNA methylation patterns in the regulatory regions through the DNA methyltransferase (DNMTs), play an important role in the development of genetic disorders and abnormal growth and maturation capacity of leukemic stem cells (LSCs).The aim of this study was to evaluate the changes in DNMT1 promoter methylation and its expression pattern in patients with ALL. Materials and Methods: In this experimental study, methylation specific PCR (MSP) was used to assess the methylation status of DNMT1 promoter regions in samples collected from ALL patients (n=45) and healthy control subjects. According to this method, un-methylated cytosine nucleotides are converted to uracil by sodium bisulfite and the proliferation of methylated and un-methylated regions are performed using specific primers for target sequences. Results: None of the patients with B and T-ALL showed methylated promoter regions of the DNMT1 gene, while the methylation pattern of both pre-B ALL patients and the control group showed a relative promoter methylation. Conclusion: Analysis of promoter methylation patterns in various subgroups of ALL has revealed the importance of DNMT1 in the regulation of gene expression. Likewise, extensive data have also highlighted the methylation-based mechanisms exerted by DNAM1 as one of the main participants regulating gene expression in B-ALL and T-ALL patients. Investigation of the overall DNA methylation pattern offers significant improvements in the prediction of disease prognosis and treatment response.

Clinical and pathologic features in Alzheimer's disease (AD) patients differ depending on the age of onset. The aim of our study was to compare the regional cerebral blood flow (rCBF) patterns of younger, elderly, and extremely elderly patients with AD with that of controls to characterize the rCBF patterns in extremely elderly patients with AD. Single photon emission CT (SPECT) was performed in 113 patients with probable AD, including 34 younger (<70 years), 41 elderly (70-84 years), and 38 extremely elderly (≥85 years) patients divided according to age at examination. The SPECT data were analyzed using three-dimensional stereotactic surface projection (3D-SSP). No significant differences regarding gender, duration of disease, education, and Mini-Mental State Examination score were found among the groups. As compared with controls, younger and elderly AD demonstrated significant reduction of rCBF in the temporo-parietal areas, posterior cingulate cortices and precunei, which is considered to be a characteristic rCBF pattern in AD. On the other hand, the extremely elderly AD group demonstrated significant reduction of rCBF in the frontal and medial temporal areas, in addition to the temporo-parietal areas, posterior cingulate cortices and precunei, but the reductions were milder than in those in younger and elderly AD groups. The extremely elderly patients with AD showed atypical rCBF patterns in AD compared to younger and elderly patients with AD. Our data suggest that pathological features in extremely elderly AD may be different from those in younger and elderly AD and that diseases different from AD, such as senile dementia of the neurofibrillary tangle type may be clinically diagnosed as extremely elderly AD.

The study compared health care utilization and costs among homeless veterans randomly assigned to peer mentors or usual care and described contacts with peer mentors. Homeless patients at four Department of Veterans Affairs clinics were randomly assigned to a peer mentor (N=195) or to usual care (N=180). Administrative data on utilization and costs over a six-month follow-up were combined with peer mentors' reports of patient contacts. Most patients (87%) in the peer mentor group had at least one peer contact. Patients in this group spent the largest proportions of time discussing housing and health issues with peer mentors and had more outpatient encounters than those in usual care, although differences were not significant. No other between-group differences were found in utilization or costs. Although significant impacts of peer mentors on health care patterns or costs were not detected, some patients had frequent contact with peer mentors.

Purpose: We aimed to estimate the optimal proportion of all gynecological cancers that should be treated with brachytherapy (BT)—the optimal brachytherapy utilization rate (BTU)—to compare this with actual gynecological BTU and to assess the effects of nonmedical factors on access to BT. Methods and Materials: The previously constructed inter/multinational guideline-based peer-reviewed models of optimal BTU for cancers of the uterine cervix, uterine corpus, and vagina were combined to estimate optimal BTU for all gynecological cancers. The robustness of the model was tested by univariate and multivariate sensitivity analyses. The resulting model was applied to New South Wales (NSW), the United States, and Western Europe. Actual BTU was determined for NSW by a retrospective patterns-of-care study of BT; for Western Europe from published reports; and for the United States from Surveillance, Epidemiology, and End Results data. Differences between optimal and actual BTU were assessed. The effect of nonmedical factors on access to BT in NSW were analyzed. Results: Gynecological BTU was as follows: NSW 28% optimal (95% confidence interval [CI] 26%-33%) compared with 14% actual; United States 30% optimal (95% CI 26%-34%) and 10% actual; and Western Europe 27% optimal (95% CI 25%-32%) and 16% actual. On multivariate analysis, NSW patients were more likely to undergo gynecological BT if residing in Area Health Service equipped with BT (odds ratio 1.76, P=.008) and if residing in socioeconomically disadvantaged postcodes (odds ratio 1.12, P=.05), but remoteness of residence was not significant. Conclusions: Gynecological BT is underutilized in NSW, Western Europe, and the United States given evidence-based guidelines. Access to BT equipment in NSW was significantly associated with higher utilization rates. Causes of underutilization elsewhere were undetermined. Our model of optimal BTU can be used as a quality assurance tool, providing an evidence-based benchmark against

Patterns of the Demographics, Clinical Characteristics, and Resource Utilization Among Maternal Decedents in Texas, 2001 - 2010: A Population-Based Cohort Study.

Contemporary reporting of maternal mortality is focused on single, mutually exclusive causes of death among a minority of maternal decedents (pregnancy-related deaths), reflecting initial events leading to death. Although obstetric patients are susceptible to the lethal effects of downstream, more proximate contributors to death and to conditions not caused or precipitated by pregnancy, the burden of both categories and related patients' attributes is invisible to clinicians and healthcare policy makers with the current reporting system. Thus, the population-level demographics, clinical characteristics, and resource utilization associated with pregnancy-associated deaths in the United States have not been adequately characterized. We used the Texas Inpatient Public Use Data File to perform a population-based cohort study of the patterns of demographics, chronic comorbidity, occurrence of early maternal demise, potential contributors to maternal death, and resource utilization among maternal decedents in the state during 2001 - 2010. There were 557 maternal decedents during study period. Chronic comorbidity was reported in 45.2%. Most women (74.1%) were admitted to an ICU. Hemorrhage (27.8%), sepsis (23.5%), and cardiovascular conditions (22.6%) were the most commonly reported potential contributing conditions to maternal death, varying across categories of pregnancy-associated hospitalizations. More than one condition was reported in 39% of decedents. One in three women died during their first day of hospitalization, with no significant change over the past decade. The mean hospital length of stay was 7.9 days and total hospital charges were $250,000 or higher in 65 (11.7%) women. The findings of the high burden of chronic illness, patterns of occurrence of a broad array of potential contributing conditions to pregnancy-associated death, and the resource-intensive needs of a large contemporary population-based cohort of maternal decedents may better inform

To evaluate the relation between Pi-deficiency syndrome (PDS) pattern and metabolic syndrome (MS) in patients with polycystic ovarian syndrome (PCOS), for exploring their internal pathologic mechanism. Among the 102 PCOS patients, 22 complicated with MS (PCOS-MS) and 80 not complicated with MS (PCOS-NMS), the Chinese medicine syndrome pattern was differentiated as PDS in 50 patients and non-PDS in 52. The clinical data, in terms of fasting blood glucose (FBG), fasting insulin (FINS), waistline, body weight (BW), stature, blood pressure (BP), etc. was collected and compared and the relation between data was analyzed. Levels of FINS and homeostasis model of assessment for insulin resistence index (HOMA-IR), in PCOS-MS patients were significantly higher than those in PCOS-NMS patients, also higher in patients of PDS pattern than those of non-PDS pattern (P 0.05). PCOS patients of PDS pattern are the high-risk population of MS, which might be related with the insulin resistance. So, early treatment of PCOS, especially on patients of PDS pattern, is of important significance for preventing the complication, as MS, of the disease.

Introduction The primary aim of this study was to determine which objectively-measured patient demographics, emergency department (ED) operational characteristics, and healthcare utilization frequencies (care factors) were associated with patient satisfaction ratings obtained from phone surveys conducted by a third-party vendor for patients discharged from our ED. Methods This is a retrospective, observational analysis of data obtained between September 2011 and August 2012 from all English- and Spanish-speaking patients discharged from our ED who were contacted by a third-party patient satisfaction vendor to complete a standardized nine-item telephone survey by a trained phone surveyor. We linked data from completed surveys to the patient’s electronic medical record to abstract additional demographic, ED operational, and healthcare utilization data. We used univariate ordinal logistic regression, followed by two multivariate models, to identify significant predictors of patient satisfaction. Results We included 20,940 patients for analysis. The overall patient satisfaction ratings were as follows: 1=471 (2%); 2=558 (3%); 3=2,014 (10%), 4=5,347 (26%); 5=12,550 (60%). Factors associated with higher satisfaction included race/ethnicity (Non-Hispanic Black; Hispanic patients), age (patients ≥65), insurance (Medicare), mode of arrival (arrived by bus or on foot), and having a medication ordered in the ED. Patients who felt their medical condition did not improve, those treated in our ED behavioral health area, and those experiencing longer wait times had reduced satisfaction. Conclusion These findings provide a basis for development and evaluation of targeted interventions that could be used to improve patient satisfaction in our ED. PMID:26265963

Objective: To investigate the pituitary hormone changes of patients with craniopharyngioma of different growth patterns during perioperative period and follow up time. Methods: Retrospective studies were performed on 212 cases of primary craniopharyngioma patient who received total tumor excision surgery in our hospital from January 2001 to May 2012. The characteristics of pituitary hormone and associated clinical manifestation during preoperative, perioperative and postoperative periods were analyzed according to the QST surgical classification. Results: One hundred and seventy-seven (83.5%) of patients present preoperative hypopituitarism, 36 of them were panhypopituitarism. The hypopituitarism condition was exacerbated during the early stage of post-operation period. The abnormal rates of HPA and HPT during the follow up were 60.1% and 58.3% respectively and hormone replacement treatment was needed for these patients. Craniopharyngioma of different growth patterns showed diversities in the characteristics of hypopituitarism. Conclusion: QST surgical classification was closely associated with the pattern of hypopituitarism, it can help to optimize treatment and prognosis estimation, and could be important criterion for improving the clinical practice of neuroendocrine monitoring, treatment and health education of patients with craniopharyngioma.

The number of preventive care guidelines is rapidly increasing. It is unknown whether the number of guideline-recommended preventive services is associated with utilization. The authors used Poisson regression of 390,778 person-years of electronic medical records data from 2008 to 2015, in 80,773 individuals aged 50-75 years. Analyses considered eligibility for 11 preventive services most closely associated with guidelines: tobacco cessation; control of obesity, hypertension, lipids, or blood glucose; influenza vaccination; and screening for breast, cervical, or colorectal cancers, abdominal aortic aneurysm, or osteoporosis. The outcome was the rate of preventive care utilization over the following year. Results were adjusted for demographics and stratified by the number of disease risk factors (smoking, obesity, hypertension, hyperlipidemia, diabetes). Data were collected in 2016 and analyzed in 2017. Preventive care utilization was lower when the number of guideline-recommended preventive services was higher. The adjusted rate of preventive care utilization decreased from 38.67 per 100 (95% CI=38.16, 39.18) in patients eligible for one guideline-recommended service to 31.59 per 100 (95% CI=31.29, 31.89) in patients eligible for two services and 25.43 per 100 (95% CI=24.68, 26.18) in patients eligible for six or more services (p-trendvalue services.

Background Approximately 1.5 million Americans are affected by Parkinson's disease [1] which includes the symptoms of postural instability and gait dysfunction. Currently, clinical evaluations of postural instability and gait dysfunction consist of a subjective rater assessment of gait patterns using items from the Unified Parkinson's Disease Rating Scale, and assessments can be insensitive to the effectiveness of medical interventions. Current research suggests the importance of cycling for Parkinson's disease patients, and while Parkinson's gait has been evaluated in previous studies, little is known about lower extremity control during cycling. The purpose of this study is to examine the lower extremity coordination patterns of Parkinson's patients during cycling. Methods Twenty five participants, ages 44-72, with a clinical diagnosis of idiopathic Parkinson's disease participated in an exercise test on a cycle ergometer that was equipped with pedal force measurements. Crank torque, crank angle and power produced by right and left leg were measured throughout the test to calculate Symmetry Index at three stages of exercise (20 Watt, 60 Watt, maximum performance). Findings Decreases in Symmetry Index were observed for average power output in Parkinson's patients as workload increased. Maximum power Symmetry Index showed a significant difference in symmetry between performance at both the 20 Watt and 60 Watt stage and the maximal resistance stage. Minimum power Symmetry Index did not show significant differences across the stages of the test. While lower extremity asymmetries were present in Parkinson's patients during pedaling, these asymmetries did not correlate to postural instability and gait dysfunction Unified Parkinson's Disease Rating Scale scores. Interpretation This pedaling analysis allows for a more sensitive measure of lower extremity function than the Unified Parkinson's Disease Rating Scale and may help to provide unique insight into current and

Full Text Available Atrial fibrillation (AF is a common arrhythmia in adults associated with thromboembolic complications. External electrical cardioversion (DCCV is a safe procedure used to convert AF to normal sinus rhythm. We sought to study factors that affect utilization of DCCV in hospitalized patients with AF. The study sample was drawn from the Nationwide Inpatient Sample (NIS of the Healthcare Cost and Utilization Project in the United States. Patients with a primary discharge diagnosis of AF that received DCCV during hospitalization in the years 2000–2010 were included. An estimated 2,810,530 patients with a primary diagnosis of AF were hospitalized between 2001 and 2010, of which 1,19,840 (4.26% received DCCV. The likelihood of receiving DCCV was higher in patients who were males, whites, privately insured, and aged < 40 years and those with fewer comorbid conditions. Higher CHADS2 score was found to have an inverse association with DCCV use. In-hospital stroke, in-hospital mortality, length of stay, and cost for hospitalization were significantly lower for patients undergoing DCCV during AF related hospitalization. Further research is required to study the contribution of other disease and patient related factors affecting the use of this procedure as well as postprocedure outcomes.

To analyze hip morphometry of femoroacetabular impingement (FAI) pattern in patients with ankylosing spondylitis (AS) and correlate them with sacroiliitis grades. 384 patients with AS were analyzed regarding demographics, radiologic signs of FAI for hip involvement, and sacroiliitis grades. FAI was classified into 3 types according to alpha angle, lateral center-edge angle and pistol grip deformity. Sacroiliitis was graded according to the New York criteria. Prevalence of FAI morphometry types was determined and evaluated for association with sacroiliitis grades. Statistical analysis regarding numerical variables, including age, sacroiliitis score using t-test, sacroiliitis score in three groups using Kruskal-Wallis test and Mann-Whitney U-test, corrected by Bonferroni methods for post hoc analysis was done. Among 384 patients, 141 (36.7%) had FAI morphometry. Male predominance was found in group with FAI pattern involvement (87.2%) (p = 0.000). Pincer type (20.6%) was the most common. Hip involvement group also showed greater sacroiliitis score (2.49 vs. 1.75, p = 0.000). Combined-type had greater sacroiliitis score compared with others (p = 0.002, 0.003). FAI morphometry was frequent in hips of AS patients (36.7%), especially pincer type, more frequent in male, and associated with significantly greater grade of sacroiliitis; combined type FAI pattern had greater sacroiliitis score.

Service provision patterns may be influenced not only by clinical oral health status leading to a diagnosis and treatment plan, but also by other variables such as patient characteristics. The main aim of this study was to investigate whether associations between services provided and patient factors would persist after controlling for the main presenting diagnosis or condition. A random sample of dentists surveyed in 1993-94 provided a response rate of 74%. Private general practitioners recorded service provision data from logs of 1-2 typical days of practice. Caries (26.5%) was the most prevalent diagnosis, followed by recall/maintenance care (19.0%), pulpal/periapical infection (10.9%), and failed restorations (10.4%). Diagnoses were associated with variation in the percentage of patients receiving services in main areas of service, and also with insurance status, sex and age distributions of patients, and type of visit (chi-square; Pservices indicated statistically significant associations with patient characteristics and diagnosis categories. Controlling for diagnosis, uninsured patients and those visiting for emergencies had less favourable service patterns (e.g., higher odds of extractions, but lower odds of preventive and crown and bridge services) compared to patients who had dental insurance or visited for check-ups or other non-emergency dental problems. The influence of these factors on services provided has implications of public health importance in terms of appropriateness of care and social inequality.

Chemotherapy is the preferred treatment regimen for advanced lung cancer patients. This study investigated the health resources utilized by and medical expenses of patients with non-small cell lung cancer (NSCLC) as well as the influence of various chemotherapy regimens on the final medical costs in China. The aim of this study was to provide physicians with a reference to use as the basis for their choice of treatment. Data were collected from the Shanghai Chest Hospital's medical charts and billing database. The collected patient information included the baseline characteristics, medical history, chemotherapy regimens, and medical costs, which were used to estimate the health resources utilized by patients and the cost of treatment. This study included 328 patients, and the average total medical cost was $US14,165. This cost included drugs, which accounted for as much as 78.91% of the total cost, and chemotherapy drugs, which accounted for 51.58% of total drug expenses. The most frequently utilized chemotherapy drug was carboplatin, and the most expensive chemotherapy drug was erlotinib. In drug combinations, gemcitabine was utilized most frequently, the combination of gemcitabine and paclitaxel was the most expensive, and cisplatin was the least expensive drug. Epidermal growth factor receptor-positive patients were treated with targeted drug therapy (icotinib, erlotinib, and gefitinib). The use of recombinant human endostatin was often combined with a vinorelbine plus cisplatin regimen. Traditional Chinese medicines were the most frequently utilized non-chemotherapy drugs, and these drugs were also the most expensive. The final cost significantly depended on the specific chemotherapy regimen; thus, the rationale and cost of the chemotherapy regimen and adjuvant chemotherapy should be considered in patients with advanced NSCLC.

The aim of this study was to determine the clinical utility of routine preoperative pelvic and abdominal computed tomography (CT) examinations in patients with endometrial cancer (EC). We retrospectively reviewed records from patients with EC who underwent a preoperative endometrial biopsy and had surgery at our institution from January 1999 through December 2008. In the subset with an abdominal CT scan obtained within 3 months before surgery, we evaluated the clinical utility of the CT scan. Overall, 224 patients (18%) had a preoperative endometrial biopsy and an available CT scan. Gross intra-abdominal disease was observed in 10% and 20% of patients with preoperative diagnosis of endometrioid G3 and type II EC, respectively, whereas less than 5% of patients had a preoperative diagnosis of hyperplasia or low-grade EC. When examining retroperitoneal findings, we observed that a negative CT scan of the pelvis did not exclude the presence of pelvic node metastasis. Alternately, a negative CT scan in the para-aortic area generally reduced the probability of finding para-aortic dissemination but with an overall low sensitivity (42%). However, the sensitivity for para-aortic dissemination was as high as 67% in patients with G3 endometrioid cancer. In the case of negative para-aortic nodes in the CT scan, the risk of para-aortic node metastases decreased from 18.8% to 7.5% in patients with endometrioid G3 EC. Up to 15% of patients with endometrioid G3 cancer had clinically relevant incidental findings that necessitated medical or surgical intervention. In patients with endometrioid G3 and type II EC diagnosed by the preoperative biopsy, CT scans may help guide the operative plan by facilitating preoperative identification of gross intra-abdominal disease and enlarged positive para-aortic nodes that are not detectable during physical examinations. In addition, CT may reveal other clinically relevant incidental findings.

Background Dry eye is a multifactorial, symptomatic disease associated with ocular surface inflammation and tear film hyperosmolarity. This study was designed to assess patterns of topical cyclosporine ophthalmic emulsion 0.05% (Restasis®) use in dry eye patients and determine if there were any differences in use based on whether dry eye is physician-coded as a primary or nonprimary diagnosis. Methods Records for adult patients with a diagnosis of dry eye at an outpatient visit from January 1, 2008 to December 31, 2009 were selected from Truven Health MarketScan® Research Databases. The primary endpoint was percentage of patients with at least one primary versus no primary dry eye diagnosis who filled a topical cyclosporine prescription. Data analyzed included utilization of topical corticosteroids, oral tetracyclines, and punctal plugs. Results The analysis included 576,416 patients, accounting for 875,692 dry eye outpatient visits: 74.7% were female, 64.2% were ages 40–69 years, and 84.4% had at least one primary dry eye diagnosis. During 2008–2009, 15.9% of dry eye patients with a primary diagnosis versus 6.5% with no primary diagnosis filled at least one cyclosporine prescription. For patients who filled at least one prescription, the mean months’ supply of cyclosporine filled over 12 months was 4.44. Overall, 33.9% of dry eye patients filled a prescription for topical cyclosporine, topical corticosteroid, or oral tetracycline over 2 years. Conclusion Patients with a primary dry eye diagnosis were more likely to fill a topical cyclosporine prescription. Although inflammation is key to the pathophysiology of dry eye, most patients seeing a physician for dry eye may not receive anti-inflammatory therapies. PMID:24179335

To compare the Doppler velocity waveform pattern of ophthalmic artery of hypertensive patients with that of normotensive subjects. Doppler velocity waveform was obtained from ophthalmic artery in 45 hypertensive patients and 60 normotensive subjects. Both hypertensives and normotensive subjects were classified according to age into those younger than and those older than 45 years. Doppler indices(pulsatility index(PI), resistance index(RI), the first systolic peak/the second systolic peak(S1/S2), the first systolic peak/diastolic peak(S1/D)) measured in hypertensive patients were compared with normotensive subjects. Among the various doppler indices, only S1/S2 showed significant difference(P < 0.05) between the hypertensive patients and normotensive subjects younger than 45 years. Doppler velocity waveform of hypertensive patients older than 45 years showed no significant difference from that of normotensive subjects with corresponding age. Doppler velocity waveform of ophthalmic artery in hypertensive patients younger than 45 years shows pattern with S2 higher than that of normotensive subjects. High S2 component(reflective-wave) may represent increased vascular impedance due to vasococonstriction of retinal arterioles in hypertensive patients

2013-01-01

Background: Elderly patients are prone to respiratory tract infections (RTIs) both; acute bronchitis and pneumonia. A large proportion of the antibiotics prescribed are unlikely to provide clinical benefit to patients. There is an increased need to decrease excess antibiotic use in elderly to minimize antibiotic resistance. Objective: To describe patterns of antimicrobial use for respiratory tract infections (RTIs) among elderly Patients and methods: A cross sectional study was conducted on one hundred elderly patients, aged > 60 years, both males and females to describe patterns of antimicrobial use for respiratory tract infections (RTIs) among elderly patients. RTIs, categorized as acute bronchitis, and pneumonia, were studied for appropriateness of antimicrobial use, type of antibiotics used, and factors associated with their use. We rated antibiotic use as appropriate (when an effective drug was used), inappropriate (when a more effective drug was indicated), or unjustified (when use of any antimicrobial was not indicated). Results: Of 100 patients with RTI, overall treatment was appropriate in 79% of episodes, inappropriate in 9%, and unjustified in 12%. For acute bronchitis, treatment was appropriate in 85% and unjustified in 15% of cases. For pneumonia, treatment was appropriate in 55% of episodes. Among the most commonly used antimicrobials, B.Lactam + macrolides their use were unjustified in 41% of cases. There were statistical significant differences in the patterns of antibiotic use when stratified by age, gender, and co- morbid conditions including chronic obstructive pulmonary disease. Conclusion: Antimicrobials are unjustifiably used for 12% of RTIs and 15% of cases of acute bronchitis, thus suggesting a need for programs to improve antibiotic prescribing at hospitals.

2015-09-01

Testicular cancer is the most common carcinoma in 20- to 40-year-old men. Eighty percent of patients with metastases achieve disease-free status with chemotherapy with or without surgical resection. Standard first-line chemotherapy is bleomycin, etoposide, and cisplatin (BEP) for three to four courses or etoposide and cisplatin (EP) for four courses. Forty percent of patients receiving chemotherapy will have permanently reduced sperm counts impairing future fertility. Sperm banking is an effective method of maintaining fertility. This retrospective study was performed to assess utilization and results from sperm banking, as well as the barriers to its use. Patients 18 and older who had received chemotherapy were given a five-item questionnaire on follow-up visit. This questionnaire included a mix of quantitative and qualitative questions. Two hundred patients enrolled in the study, and all 200 completed the questionnaire. Of the two hundred, 139 (70 %) patients chose not to bank sperm; 71 (51 %) of those were not interested, 25 (18 %) declined due to desire to start chemotherapy, 24 (17 %) were not offered, 12 (9 %) declined due to cost, and 7 (5 %) answered "other." The average age at cancer diagnosis of patients who banked sperm was 28.4 as opposed to 32.6 for patients who did not (p = 0.003). The percentage of patients that had children before their diagnosis was 21 % in the sperm banking group, and 50 % in the group that did not (p = 0.0002). Sixty-one (30 %) chose to bank sperm; 11 of 61 patients (18 %) utilized the banked sperm; 9 of 11 (82 %) patients that utilized were successful; and 3 of 9 (33 %) successes resulted in multiple gestations. Sperm banking provides the opportunity for paternity in testicular cancer patients with reduced sperm counts following treatment. However, the majority of these patients chose not to bank sperm or were not offered the opportunity. A range of factors such as time, emotional state, patient age, disease stage, prior

To identify the key risk factors and explain the spatiotemporal patterns of childhood asthma in the Memphis metropolitan area (MMA) over an 11-year period (2005-2015). We hypothesize that in the MMA region this burden is more prevalent among urban children living south, downtown, and north of Memphis than in other areas. We used a large-scale longitudinal electronic health record database from an integrated healthcare system, Geographic information systems (GIS), and statistical and space-time models to study the spatiotemporal distributions of childhood asthma at census tract level. We found statistically significant spatiotemporal clusters of childhood asthma in the south, west, and north of Memphis city after adjusting for key covariates. The results further show a significant increase in temporal gradient in frequency of emergency department (ED) visits and inpatient hospitalizations from 2009 to 2013, and an upward trajectory from 4 per 1,000 children in 2005 to 16 per 1,000 children in 2015. The multivariate logistic regression identified age, race, insurance, admit source, encounter type, and frequency of visits as significant risk factors for childhood asthma (p asthma burden and healthcare utilization for African American (AA) patients living in a high-risk area than those living in a low-risk area in comparison to the white patients: AA vs. white [odds ratio (OR) = 3.03, 95% confidence interval (CI): 2.75-3.34]; and Hispanic vs. white (OR = 1.62, 95% CI: 1.21-2.17). These findings provide a strong basis for developing geographically tailored population health strategies at the neighborhood level for young children with chronic respiratory conditions.

Due to the increasing prevalence of arteriosclerosis and the mortality caused by this disease, Coronary Artery Bypass Graft (CABG) has become one of the most common surgical procedures. Utilization of patient education is approved as an effective solution for increasing patient survival and outcomes of treatment. However, failure to consider different aspects of patient education has turned this goal into an unattainable one. The objective of this research was to determine the effect of utilizing the organizational culture improvement model of patient education on CABG patients' anxiety and satisfaction. The present study is a randomized controlled trial. This study was conducted on eighty CABG patients. The patients were selected from the CCU and Post-CCU wards of a hospital affiliated with Iran University of Medical Sciences in Tehran, Iran, during 2015. Eshpel Burger's Anxiety Inventory and Patients' Satisfaction Questionnaire were used to collect the required information. Levels of anxiety and satisfaction of patients before intervention and at the time of release were measured. The intervention took place after preparing a programmed package based on the organizational culture improvement model for the following dimensions: effective communication, participatory decision-making, goal setting, planning, implementation and recording, supervision and control, and improvement of motivation. After recording the data, it was analyzed in the chi-square test, t-independent and Mann-Whitney U tests. The significance level of tests was assumed to be 0.05. SPSS version 18 was also utilized for data analysis. Research results revealed that variations in the mean scores of situational and personality anxiety of the control and experiment group were descending following the intervention, but the decrease was higher in the experiment group (p≤0.0001). In addition, the variations of the mean scores of patients' satisfaction with education were higher in the experiment group

This study is performed to encourage cancer patients to identify, relieve and effectively overcome the stress caused by radiotherapy, by analyzing stress reactions and coping patterns of cancer patients who perceived stress due to radiotherapy. The study group was composed of 85 cancer patients of the age 20 or higher who were undergoing radiotherapy in four hospitals located in Seoul and Kyonggi-do. The survey questionnaire was used, which had 161 questions inquiring respondents of general status, perceived stress, stress reactions and coping patterns. The surveyed data were analyzed by a SAS program, which employed descriptive statistics. Pearson Correlation Coefficient, t-test, ANOVA and Stepwised Multiple Regression. The stress perception and reaction rates were low in cancer patients comparing to patients of the other study. In the coping patterns. the problem-focused coping patterns were significantly higher than emotion-focused coping patterns. The statistically meaningful differences were observed in the stress perception and reactions depending on the time of diagnosis and perceived health level. As for the problem-focused coping patterns, significant differences were found depending on age, marital status, education, income and the number of family members as well as perceived health level of patients. The level of perceived stress and that of stress reactions was found to have positively significant correlation(r=.764, p<.001) while the perceived stress and the problem-focused coping patterns was correlated negatively (r=-.288, p<.01). The stress reactions and the problem-focused coping patterns was found to have negatively significant correlation(r=-.289, p<.01). The problem-focused coping behavior, which cooperated with doctors, technologists, nurses and families of cancer patients, is advisable for the cancer patients to overcome uncertainty and uneasiness by effectively release the stress.

Post-poliomyelitis syndrome causes variable musculoskeletal manifestations including pain, muscle weakness and fatigue. These manifestations are commonly secondary to overuse and misuse of muscles and joints and could follow a fall. Bone scan can be useful in determining the underlying cause and follow-up. The objective of this study was to describe the late scintigraphic patterns on bone scan following poliomyelitis. Bone scans of 8 adult patients (7 female and 1 male), aged 35 to 53 years, who were known to have paralytic poliomyelitis, were retrospectively studied. Six patients had unilateral while 1 had bilateral disease. All patients had three-phase bone scan and 5 had SPECT study as well. Studies were reviewed by two qualified nuclear medicine physicians and findings were recorded and analyzed. Several patterns were consistently identified: decreased blood pool activity in the affected lower limb of all patients; deformed ipsilateral hemi-pelvis with reduced uptake on the affected side in all patients with unilateral disease; stress changes with increased uptake in the bones of the contra-lateral lower extremity; and degenerative changes in multiple joints (shoulder, knee, hip, ankle and spine). Significant scoliosis was only noted in the patient with bilateral disease. Scintigraphic patterns on bone scan associated with the post-poliomyelitis syndrome and persistent weakness following a distant episode of poliomyelitis have been described. Awareness of these characteristic scintigraphic findings may facilitate an accurate diagnosis and lead to more appropriate patient management. (orig.)

Full Text Available Traveling to seek specialized care such as liver transplantation (LT is a reality in the United States. Patient migration has been attributed to organ availability. The aims of this study were to delineate patterns of patient migration and outcomes after LT.All deceased donor LT between 2008-2013 were extracted from UNOS data. Migrated patients were defined as those patients who underwent LT at a center in a different UNOS region from the region in which they resided and traveled a distance > 100 miles.Migrated patients comprised 8.2% of 28,700 LT performed. Efflux and influx of patients were observed in all 11 UNOS regions. Regions 1, 5, 6, and 9 had a net efflux, while regions 2, 3, 4, 7, 10, and 11 had a net influx of patients. After multivariate adjustment for donor and recipient factors, graft (p = 0.68 and patient survival (p = 0.52 were similar between migrated and non-migrated patients.A significant number of patients migrated in patterns that could not be explained alone by regional variations in MELD score and wait time. Migration may be a complex interplay of factors including referral patterns, specialized services at centers of excellence and patient preference.

Pyruvate oxidase influences the sugar utilization pattern and capsule production in Streptococcus pneumoniae.

Directory of Open Access Journals (Sweden)

Sandra M Carvalho

Full Text Available Pyruvate oxidase is a key function in the metabolism and lifestyle of many lactic acid bacteria and its activity depends on the presence of environmental oxygen. In Streptococcus pneumoniae the protein has been suggested to play a major role in metabolism and has been implicated in virulence, oxidative stress survival and death in stationary phase. Under semi-aerobic conditions, transcriptomic and metabolite profiling analysis of a spxB mutant grown on glucose showed minor changes compared to the wild type, apart from the significant induction of two operons involved in carbohydrate uptake and processing. This induction leads to a change in the sugar utilization capabilities of the bacterium, as indicated by the analysis of the growth profiles of the D39 parent and spxB mutant on alternative carbohydrates. Metabolic analysis and growth experiments showed that inactivation of SpxB has no effect on the glucose fermentation pattern, except under aerobic conditions. More importantly, we show that mutation of spxB results in the production of increased amounts of capsule, the major virulence factor of S. pneumoniae. Part of this increase can be attributed to induction of capsule operon (cps transcription. Therefore, we propose that S. pneumoniae utilizes pyruvate oxidase as an indirect sensor of the oxygenation of the environment, resulting in the adaption of its nutritional capability and the amount of capsule to survive in the host.

Quality of life (QoL) is an important clinical outcome in cancer patients. We investigated associations between dietary patterns and QoL changes in colorectal cancer (CRC) patients. The study included 192 CRC patients with available EORTC QLQ-C30 data before and 12 months post-surgery and food frequency questionnaire data at 12 months post-surgery. Principal component analysis was used to identify dietary patterns. Multivariate regression models assessed associations between dietary patterns and QoL changes over time. We identified four major dietary patterns: "Western" dietary pattern characterized by high consumption of potatoes, red and processed meat, poultry, and cakes, "fruit&vegetable" pattern: high intake of vegetables, fruits, vegetable oils, and soy products, "bread&butter" pattern: high intake of bread, butter and margarine, and "high-carb" pattern: high consumption of pasta, grains, nonalcoholic beverages, sauces and condiments. Patients following a "Western" diet had lower chances to improve in physical functioning (OR = 0.45 [0.21-0.99]), constipation (OR = 0.30 [0.13-0.72]) and diarrhea (OR: 0.44 [0.20-0.98]) over time. Patients following a "fruit&vegetable" diet showed improving diarrhea scores (OR: 2.52 [1.21-5.34]. A "Western" dietary pattern after surgery is inversely associated with QoL in CRC patients, whereas a diet rich in fruits and vegetables may be beneficial for patients' QoL over time.

Pregnancy is a special physiological condition, where drug treatment presents a special concern. To evaluate the drug utilization pattern during pregnancy and to evaluate the effect of the educational and economic status on it.. The retrospective cross-sectional study. The postgraduate Department of Pharmacology and Therapeutics of a medical college. and the antenatal clinic of the institution. Medical students filled 405 questionnaires after interviewing pregnant women (243 primigravida and 152 multigravida). All the collected questionnaires were analysed for various study parameters. Inter-group comparison was done using chi-square test. P value drugs, with an average of 1.73, 2.89 and 2.49 drugs per pregnant women, were used during first, second and third trimester of pregnancy, respectively. A majority of the drugs used, were from category-A, followed by category-B and category-D. However, category C and X drugs constituted 2.90 (20) and 5.71% (40) of drugs used during the third trimester and first trimester, respectively. Herbal/homeopathic drugs constituted 6.42 (45), 3.68 (40) and 1.46% (10) of the drugs used in the first, second and third trimester of pregnancy, respectively (P=649). 33.33% (135) women believed that drug use during pregnancy is dangerous to both mother and child and 37.03% (150) believed that drugs are dangerous throughout pregnancy. 55.55% (225) females advocated the use of iron/folic acid during pregnancy. 24.69% (100) of women had knowledge about barrier contraceptives. Self-medication and homeopathic/ herbal drugs use was found more in graduates than in undergraduates; as well as, it was more in the higher socioeconomic group than the lower socioeconomic group. There is a need to educate and counsel women of child-bearing age, regarding the advantages and disadvantages of drug use during pregnancies, with special reference to alternative therapies and self-medication.

Shinbane, Jerold S; Saxon, Leslie A

Advances in imaging technology have led to a paradigm shift from planning of cardiovascular procedures and surgeries requiring the actual patient in a "brick and mortar" hospital to utilization of the digitalized patient in the virtual hospital. Cardiovascular computed tomographic angiography (CCTA) and cardiovascular magnetic resonance (CMR) digitalized 3-D patient representation of individual patient anatomy and physiology serves as an avatar allowing for virtual delineation of the most optimal approaches to cardiovascular procedures and surgeries prior to actual hospitalization. Pre-hospitalization reconstruction and analysis of anatomy and pathophysiology previously only accessible during the actual procedure could potentially limit the intrinsic risks related to time in the operating room, cardiac procedural laboratory and overall hospital environment. Although applications are specific to areas of cardiovascular specialty focus, there are unifying themes related to the utilization of technologies. The virtual patient avatar computer can also be used for procedural planning, computational modeling of anatomy, simulation of predicted therapeutic result, printing of 3-D models, and augmentation of real time procedural performance. Examples of the above techniques are at various stages of development for application to the spectrum of cardiovascular disease processes, including percutaneous, surgical and hybrid minimally invasive interventions. A multidisciplinary approach within medicine and engineering is necessary for creation of robust algorithms for maximal utilization of the virtual patient avatar in the digital medical center. Utilization of the virtual advanced cardiac imaging patient avatar will play an important role in the virtual health care system. Although there has been a rapid proliferation of early data, advanced imaging applications require further assessment and validation of accuracy, reproducibility, standardization, safety, efficacy, quality

Objective:To detect the serum proteomic patterns of patients with non-small cell lung (NSCLC) treated with radiochemotherapy by surface enhanced laser desorption ionization time of flight mass spectrometry (SELDI-TOF-MS) protein chip array techniques, and to screen differential expression protein and observe the changes between the patterns before and after the treatment. Methods: SELDI-TOF-MS and CM-10 protein chips were used to detect the serum proteomic patterns of 35 healthy persons (normal control) and 35 patients with NSCLC before radiochemotherapy. Twenty-six out of the 35 patients after the treatment were also studied. BioMarker Wizard 3.01 and BioMarker Pattern System 5. 01 were used in combination to analyze the data and to develop diagnostic models. Results: Sixteen differential expression protein peaks from a total of 251 protein peaks were automatically chosen, including 8 high expressions and 8 low expressions in patients with NSCLC. Of the 16 protein peaks, 6 protein peak patterns ( M 2 572.1, M 2 885.8, M 3 870.4, M 4 161.4, M 5 739.7 and M 8 164.3 mass/charge ratio [ m/z] ) were observed in model that could be used to distinguish lung cancer' from non-cancer diseases. The sensitivity and specificity results were 91% (32/35)and 83% (29/35). When the SELDI marker pattern was tested with the blinded test set, the sensitivity and specificity were 80% (28/35) and 71% (25/35). The 16 differential expression protein peaks of patients before and after the treatment were obviously different. But the peaks of patients after the treatment trended to those of the normal control. Of the 16 protein peaks, M 2 572.1, M 2 885.8, M 4 664.78, M 9 228.39 and M 9 396.42 were significantly changed. Conclusions: SELDI-TOF-MS is possibly significant for screening differential expression proteins and assessing the treatment efficacy and prognosis of patients, which needs to be demonstrated by further study.

In this short communication we present a re-analysis of homeopathic patient data in comparison to control patient data from the same Outpatient´s Unit "Homeopathy in malignant diseases" of the Medical University of Vienna. In this analysis we took account of a probable immortal time bias. For patients suffering from advanced stages of cancer and surviving the first 6 or 12 months after diagnosis, respectively, the results show that utilizing homeopathy gives a statistically significant (p<0.001) advantage over control patients regarding survival time. In conclusion, bearing in mind all limitations, the results of this retrospective study suggest that patients with advanced stages of cancer might benefit from additional homeopathic treatment until a survival time of up to 12 months after diagnosis.

Over the past few decades, lifespans of sickle cell disease (SCD) patients have increased; hence, they encounter multiple complications. Early detection, appropriate comprehensive care, and treatment may prevent or delay onset of complications. We collected longitudinal data on sickle cell disease (SCD) complication rates and associated resource utilization relative to blood transfusion patterns and iron chelation therapy (ICT) use in patients aged ≥16 years to address a gap in the literature. Medical records of 254 SCD patients ≥16 years were retrospectively reviewed at three US tertiary care centers. We classified patients into cohorts based on cumulative units of blood transfused and ICT history: ICT (Cohort 1 [C1]), ≥15 units, no ICT (Cohort 2 [C2]), and ≥15 units with ICT (Cohort 3 [C3]). We report SCD complication rates per patient per year; cohort comparisons use rate ratios (RRs). Cohorts had 69 (C1), 91 (C2), and 94 (C3) patients. Pain led to most hospitalizations (76%) and emergency department (ED) (82%) visits. Among transfused patients (C2+C3), those receiving ICT were less likely to experience SCD complications than those who did not (RR [95% CI] C2 vs. C3: 1.33 [1.25-1.42]). Similar trends (RR [95% CI]) were observed in ED visits and hospitalizations associated with SCD complications (C2 vs. C3, ED: 1.94 [1.70-2.21]; hospitalizations: 1.61 [1.45-1.78]), but not in outpatient visits. Although the most commonly reported SCD complication among all patients was pain, patients who received ICT were less likely to experience pain and other complications than those who did not. These results highlight the need for increased patient and provider education on the importance of comprehensive disease management.

Prior studies of the utilization of mental health professionals by sexual minority populations have relied on data that are now dated or not nationally representative. These studies have also provided mixed findings regarding gender differences in the utilization of mental health professionals among sexual minority individuals. Using data from the 2013-2015 National Health Interview Surveys, this study investigates (1) how sexual minority individuals compare to heterosexual participants in their utilization of mental health professionals; and (2) gender differences in that utilization. The results indicate sexual minority individuals utilize mental health care professionals at higher rates than heterosexual individuals even after controlling for measures of mental health and other demographic characteristics; this is true for both men and women. However, gender moderates the sexual minority effect on utilization rates. Sexual minority men utilize mental health professionals at a high rate, such that their utilization rates are similar to sexual minority women, contrary to the gender gap seen among heterosexuals.

Examination of practice patterns compared to existing evidence identifies knowledge to practice gaps. To describe the utilization of pharmacological, patient education, primary psychological interventions and relaxation therapies in patients with neck pain by clinicians. An international cross-sectional survey was conducted to determine the use of these interventions amongst 326 clinicians treating patients with neck pain. Nineteen countries participated. Results were analyzed by usage amongst physical therapists (39%) and chiropractors (35%), as they were the predominant respondents. Patient education (95%) and relaxation therapies (59%) were the most utilized interventions. Tests of subgroup differences determined that physical therapists used patient education significantly more than chiropractors. Use of medications and primary psychological interventions were reported by most to be outside of scope of practice. The high rate of patient education is consistent with supporting evidence. However, usage of relaxation therapies is contrary to evidence suggesting no benefit for improved pain or function for chronic neck pain. This survey indicates that patient education and relaxation therapies are common treatments provided by chiropractors and physical therapists for patients with neck pain. Future research should address gaps associated with variable practice patterns and knowledge translation to reduce usage of interventions shown to be ineffective.

Context: In medical and veterinary medical education the use of problem-based and cased-based learning has steadily increased over time. At veterinary faculties, this development has mainly been evident in the clinical phase of the veterinary education. Therefore, a consortium of teachers of biochemistry and physiology together with technical and didactical experts launched the EU-funded project "vetVIP", to create and implement veterinary virtual patients and problems for basic science instruction. In this study the implementation and utilization of virtual patients occurred at the veterinary faculties in Budapest, Hannover and Lublin. Methods: This report describes the investigation of the utilization and acceptance of students studying veterinary basic sciences using optional online learning material concurrently to regular biochemistry and physiology didactic instruction. The reaction of students towards this offer of clinical case-based learning in basic sciences was analysed using quantitative and qualitative data. Quantitative data were collected automatically within the chosen software-system CASUS as user-log-files. Responses regarding the quality of the virtual patients were obtained using an online questionnaire. Furthermore, subjective evaluation by authors was performed using a focus group discussion and an online questionnaire. Results: Implementation as well as usage and acceptance varied between the three participating locations. High approval was documented in Hannover and Lublin based upon the high proportion of voluntary students (>70%) using optional virtual patients. However, in Budapest the participation rate was below 1%. Due to utilization, students seem to prefer virtual patients and problems created in their native language and developed at their own university. In addition, the statement that assessment drives learning was supported by the observation that peak utilization was just prior to summative examinations. Conclusion: Veterinary

Amplification of the human epidermal growth factor receptor 2 (HER2) gene occurs in approximately 20% of invasive breast cancer cases and is associated with a more aggressive disease course than HER2-negative breast cancer. HER2-targeted therapies have altered the natural history of HER2-positive breast cancer, a trend that will likely further improve with the recent approval of new agents. A prospective, observational cohort study was designed and initiated to provide real-world insights into current treatment patterns, long-term survival, and patients’ experiences with initial and subsequent treatments for HER2-positive metastatic breast cancer (MBC). The Systematic Therapies for HER2-positive Metastatic Breast Cancer Study (SystHERs) is a US-based prospective observational cohort study enrolling patients ≥18 years of age with recently diagnosed HER2-positive MBC not previously treated with systemic therapy in the metastatic setting. The primary objective of the study is to identify treatment patterns and clinical outcomes in recently diagnosed patients in a variety of practice settings. Secondary objectives include comparative efficacy, safety, and patient-reported outcomes (PROs). Healthcare resource utilization is an exploratory end point. Tumor tissue and blood sample collection is optional. The SystHERs registry will enroll approximately 1000 patients over a 3-year period, after which the study will continue for ≥5 years, allowing for a maximum follow-up of 8 years. The treating physician will determine all care and the frequency of visits. PRO measures will be completed at study enrollment and every 90 days. Clinical data will be abstracted quarterly from patient records. The first patient was enrolled in June 2012, and preliminary descriptive data based on 25% to 30% of the final study population are expected at the end of 2013, and as of April 25, 2014, 386 patients are enrolled. SystHERs is expected to provide in-depth data on demographic

To evaluate the health system costs among patients with hemophilia A and B with and without inhibitors over 5 years. This was a retrospective, observational study utilizing medical and pharmacy electronic medical records and administrative encounters/claims data tracking US patients between 2006-2011. Patients with diagnosis codes for hemophilia A and B were identified. Patients with inhibitors were characterized by utilization of bypassing agents activated prothrombin complex concentrate or factor VIIa on two or more distinct dates. Severity was classified as mild, moderate, or severe based on laboratory tests of clotting factor. There were 160 hemophilia A patients and 54 hemophilia B patients identified. From this group, seven were designated as patients with inhibitors (five with hemophilia A and two with hemophilia B). Hemophilia A patients without inhibitors reported 65 (41.9%) as being severe, 19 (12.3%) as moderate, and 71 (45.8%) as mild. Hemophilia B patients without inhibitors reported nine (17.3%) had severe, 13 (25.0%) had moderate, and 30 (57.7%) had mild hemophilia. All patients with inhibitors had been hospitalized in the previous 5 years compared to 64 (41.3%) with hemophilia A without inhibitors and 22 (42.3%) with hemophilia B without inhibitors. The median aggregate cost per year (including factor and health resource use) was $325,780 for patients with inhibitors compared to $98,334 for hemophilia A patients without inhibitors and $23,265 for hemophilia B patients without inhibitors. The results suggest that, while the frequency of inhibitors within the hemophilia cohort was low, there was a higher frequency of hospitalizations, and the associated median aggregate costs per year were 3-fold higher than those patients without inhibitors. In contrast, hemophilia B patients experience less severe disease and account for lower aggregate yearly costs compared to either patients with hemophilia A or patients with inhibitors.

The gut is an important target organ of injury during critically ill conditions. Although Gram staining is a common and quick method for identifying bacteria, its clinical application has not been fully evaluated in critically ill conditions. This study's aims were to identify patterns of Gram-stained fecal flora and compare them to cultured bacterial counts and to investigate the association between the patterns and septic complications in patients with severe systemic inflammatory response syndrome (SIRS). Fifty-two patients with SIRS were included whose Gram-stained fecal flora was classified into three patterns. In a diverse pattern, large numbers of multiple kinds of bacteria completely covered the field. In a single pattern, one specific kind of bacteria or fungi predominantly covered the field. In a depleted pattern, most bacteria were diminished in the field. In the analysis of fecal flora, the numbers of total obligate anaerobes in the depleted pattern was significantly lower than those in the diverse pattern and single pattern (p Gram-stained fecal flora can be classified into three patterns and are associated with both cultured bacterial counts and clinical information. Gram-stained fecal bacteria can be used as a quick bedside diagnostic marker for severe SIRS patients.

To determine how age and gender impact resource utilization and profitability in patients seen and released from an Emergency Department (ED). Billing data for patients seen and released from an Emergency Department (ED) with >100,000 annual visits between 2003 and 2009 were collected. Resource utilization was measured by length of stay (placement in ED bed to leaving the bed) and direct clinical costs (e.g., ED nursing salary and benefits, pharmacy and supply costs, etc.) estimated using relative value unit cost accounting. The primary outcome of profitability was defined as contribution margin per hour. A patient's contribution margin by insurance type (excluding self-pay) was determined by subtracting direct clinical costs from facility contractual revenue. Results are expressed as medians and US dollars. In 523 882 outpatient ED encounters, as patients' aged, length of stay and direct clinical cost increased while the contribution margin and contribution margin by hour decreased. Women of childbearing age (15-44) had higher median length of stay (2.1 hours), direct clinical cost ($149), and contribution margin per hour ($103/hour) than men of same age (1.7, $131, $85/hour, respectively). Resource utilization and profitability by gender were similar in children and adults over 45. Resource utilization increased and profitability decreased with increasing age in patients seen and released from an ED. The care of women of childbearing age resulted in higher resource utilization and higher profitability than men of the same age. No differences in resource utilization or profitability by gender were observed in children and adults over 45. Copyright © 2014 Elsevier Inc. All rights reserved.

Many patients with gynecological disorders seek traditional medicine consultations in Asian countries. This study intended to investigate the utilization of traditional Chinese medicine (TCM) in patients with dysfunctional uterine bleeding (DUB) in Taiwan. We analyzed a cohort of one million individuals randomly selected from the National Health Insurance Research Database in Taiwan. We included 46,337 subjects with newly diagnosed DUB (ICD-9-CM codes 626.8) from January 1, 1997 to December 31, 2010. The patients were categorized into TCM seekers and non-TCM seekers according to their use of TCM. Among the subjects, 41,558 (89.69%) were TCM seekers and 4,779 (10.31%) were non-TCM seekers. Patients who were younger tended to be TCM seekers. Most of the patients had also taken Western medicine, especially tranexamic acid and non-steroidal anti-inflammatory drugs (NSAIDs). More than half of TCM seekers (55.41%) received combined treatment with both Chinese herbal remedies and acupuncture. The most commonly used TCM formula and single herb were Jia-Wei-Xiao-Yao-San (Bupleurum and Peony Formula) and Yi-Mu-Cao (Herba Leonuri), respectively. The core pattern of Chinese herbal medicine for DUB patients consisted of Jia-Wei-Xiao-Yao-San, Xiang-Fu (Rhizoma Cyperi), and Yi-Mu-Cao (Herba Leonuri). TCM use is popular among patients with DUB in Taiwan. Further pharmacological investigations and clinical trials are required to validate the efficacy and safety of these items.

Despite the overruling impact of light in the phyllosphere, little is known regarding the influence of light spectra on non-phototrophic bacteria colonizing the leaf surface. We developed an in vitro method to study phenotypic profile responses of bacterial pure cultures to different bands of the visible light spectrum using monochromatic (blue: 460 nm; red: 660 nm) and polychromatic (white: 350-990 nm) LEDs, by modification and optimization of a protocol for the Phenotype MicroArray™ technique (Biolog Inc., CA, USA). The new protocol revealed high reproducibility of substrate utilization under all conditions tested. Challenging the non-phototrophic bacterium Pseudomonas sp. DR 5-09 with white, blue, and red light demonstrated that all light treatments affected the respiratory profile differently, with blue LED having the most decisive impact on substrate utilization by impairing respiration of 140 substrates. The respiratory activity was decreased on 23 and 42 substrates under red and white LEDs, respectively, while utilization of one, 16, and 20 substrates increased in the presence of red, blue, and white LEDs, respectively. Interestingly, on four substrates contrasting utilization patterns were found when the bacterium was exposed to different light spectra. Although non-phototrophic bacteria do not rely directly on light as an energy source, Pseudomonas sp. DR 5-09 changed its respiratory activity on various substrates differently when exposed to different lights. Thus, ability to sense and distinguish between different wavelengths even within the visible light spectrum must exist, and leads to differential regulation of substrate usage. With these results, we hypothesize that different light spectra might be a hitherto neglected key stimulus for changes in microbial lifestyle and habits of substrate usage by non-phototrophic phyllospheric microbiota, and thus might essentially stratify leaf microbiota composition and diversity.

Recently published articles have established that a substantial number of cancer patients utilize the Internet to gather information about their respective diagnoses. The challenges for medical providers include understanding the prevalence and characteristics of patients using the Internet, reasons for Internet use, and the effectiveness of currently available websites in providing useful health-related information to patients. Adults with cancer were asked to complete a self-administered, anonymous, 21-item questionnaire upon registration at the Alvin J. Siteman Cancer Center at the Washington University School of Medicine. There were 500 respondents (mean age 58 years (range 18-90), 83% Caucasian and 15% African-American). Three hundred ninety-eight participants (80%) reported access to the Internet, and 315 (63%) reported searching for information about cancer on the Internet. Patients accessing the Internet for cancer information were younger than those who did not (median age 56 vs. 63 years; p Internet usage for cancer information also differed by race (p Internet for cancer information, 13.3% of patients had their decisions towards treatments affected or changed, and 11.4% of patients had their choice in physicians affected or changed because of Internet use; 23.5% of patients sought information on clinical trials, and 9.5% of patients were influenced or changed their decision regarding clinical trial enrollment due to Internet information. Approximately two thirds of patients with cancer used the Internet to obtain information about their disease. Factors affecting Internet use for cancer information included age, race, and education. Clinical decisions can be affected by Internet use.

Background: Due to great technological progress made over the last decade in computer tomography, CT Has become a very successful tool for diagnostic imaging in polytraumatic patients. The purpose of this study is an optimum selection of parameters to detect all post-traumatic pathologies in polytraumatic patients, with the application of minimum ionizing radiation. Material/Methods: 131 patients with a suspected polytrauma were studied following various scanning patterns with a 64-slice CT of the head, neck, thorax and abdominal cavity with pelvis. The patients were divided into three groups in accordance with the chosen scheme. Materials were analyzed with the following in view: increasing the efficacy of detecting pathologies, decreasing radiation dose, simplifying assessment and facilitating image archiving. Results: The following mean numbers of serious post-traumatic pathologies were diagnosed during one examination: group I - 1.8, group II - 2.8, and group III - 2.1. There was a statistically significant reduction in the number of reconstructions performed during one examination from 11.8 in group I, 8.3 in group II, to 7.2 in group III. Additionally, statistically significant reductions were obtained in the mean values of the dose-length product (DLP): 3361 mGy · cm (group I), 2805 mGy 8· cm (group II), 2583 mGy · cm (group III). Conclusions: The third scanning pattern, which comprised multiple adjacent sections scanned jointly, including a single trunk scan following the administration of a contrast material, is best in terms of evaluation comfort and the lowest radiation dose absorbed by the patient. Patterns II and III are most effective in detecting pathologies. (authors)

Complementary and alternative therapies in treating atopic dermatitis are not uncommon. However, substantial evidence and consensus on treating atopic dermatitis is lacking. The aim of this study is to investigate the characteristics and utilization of traditional Chinese medicine in patients with atopic dermatitis. We retrospectively collected patients with atopic dermatitis at the Chang Gung Memorial Hospital in Taiwan between 2002 and 2011. Patients' demographic data, duration and frequency of treatment, serum total immunoglobulin E levels, and traditional Chinese medicine treatment principles and prescription were analyzed. There were 4145 patients (8.8%) received traditional Chinese medicine therapy between 2002 and 2011. Among them, 2841 (68.54%) chose TCM only and 1304 (31.46%) chose to combine TCM and WM therapies. Those who chose combination therapy were younger, and needed more times of visit and longer duration of treatment. The most frequent comorbid conditions accompany atopic dermatitis were allergic rhinitis (46.06%) and asthma (21.46%). Among the 87,573 prescriptions written for Chinese medicine, the most frequently prescribed herbal formula and single herb were Xiao-Feng-San (Eliminate Wind Powder) (16.98%) and Bai-Xian-Pi (Cortex Dictamni) (12.68%), respectively. The most commonly used therapeutic principles of herbal formulas and single herbs were releasing exterior (20.23%) and clearing heat (41.93%), respectively. Our hospital-based study characterized the utilization patterns of traditional Chinese medicine in atopic dermatitis patients. This information could be used as references for clinical application and provide valuable information for future clinical trials. Copyright © 2013 Elsevier Ltd. All rights reserved.

Careful consideration of the benefit to the mother and risk to the foetus, is required, while prescribing drugs during pregnancy. To assess the pattern of drug utilization during pregnancy and to explore the knowledge, attitude and awareness on drug use by the antenatal mother in a tertiary care hospital setup in western India. Observational, cross-sectional study involved holding interviews on 501 pregnant women, in OPD and IPD of Obstetrics-Gynaecology Department using a pilot-based questionnaire, was done. Data from prescriptions and case-files were also collected. Drugs were classified pharmacologically and according to teratogenic potential using U.S.FDA classification. Study population was classified according to the trimester of pregnancy and educational and socioeconomic status. Intergroup comparison was done using Chi-square test. Majority of the drugs were from Category A(71.2%) and Category B (16.5%), followed by those from Categories C(9.09%), D(1.12%) and X(0.7%). Category A drugs were significantly used more in first trimester, while Category C and D drugs were used in the last two trimesters (pwomen believed that drug use in pregnancy could be harmful to both mother and baby, while 35.52% believed that drug use could be dangerous throughout pregnancy. Patients' educational and socio-economic statuses influenced their compliance for nutritional supplements prescribed during pregnancy and their awareness on common contraceptive methods. Higher education and socioeconomic class provided information on safety of barrier contraception during pregnancy. Study revealed careful prescribing behaviour of physicians. Lack of awareness on safety of drugs in pregnancy and contraceptive use advocates a need for educating and counselling women of child bearing ages.

Full Text Available Abstract Background and purpose:Now-a-days, patient satisfaction is increasingly receiving the attention of health-service providers, which is a necessary step to enhance the quality of health services. The present study aimed at exploring patient-physician communicative patterns, physicians’ job satisfaction, and patients’ satisfaction at Isfahan, Iran. Materials and Methods:This study was a descriptive analytical and cross-sectional survey in the summer of 2010. Simple random sampling was used to select participants. Data were collected through using three self-designed questionnaires on physicians’ job satisfaction, patient-physician relationship patterns (based on Hollander and Szase’ ideas, and patients’ satisfaction. Validity of the questionnaire was checked by a panel of experts. Furthermore, internal consistency reliability of the questionnaires was confirmed by Cronbach’s alpha (α = 0.80. Different dimensions of the job satisfaction questionnaire were salary, supervision, setting, promotion, fringe benefits, and working conditions. Data were analyzed by using SPSS for Windows 13.0 software. Results:The mean score of patient-physician relationship was 63. Therefore, the most frequent patient-physician communication pattern was guidance-cooperation. The mean score of physician’ job satisfaction was 50.2. The mean score of patients’ satisfaction was 86.5. Physicians’ job satisfaction was found to be related to patient-physician communication pattern (P < 0.05. Conclusion:Although patient-physician communication patterns are important, different variable such as patients’ and physicians’ satisfaction influence the patterns. Furthermore, improvement communication process between health care providers can be useful in the increasing patient satisfaction and patient quality of care.

Full Text Available Objective. To compare Visual Analogue Scale (VAS scores with overall postoperative pain medication requirements including cumulative dose and patterns of medication utilization and to determine whether VAS scores predict pain medication utilization. Methods. VAS scores and pain medication data were collected from participants in a randomized trial of the utility of phenazopyridine for improved pain control following gynecologic surgery. Results. The mean age of the 219 participants was 54 (range19 to 94. We did not detect any association between VAS and pain medication utilization for patient-controlled anesthesia (PCA or RN administered (intravenous or oral medications. We also did not detect any association between the number of VAS scores recorded and mean pain scores. Conclusion. Postoperative VAS scores do not predict pain medication use in catheterized women inpatients following gynecologic surgery. Increased pain severity, as reflected by higher VAS scores, is not associated with an increase in pain assessment. Our findings suggest that VAS scores are of limited utility for optimal pain control. Alternative or complimentary methods may improve pain management.

Resource utilization and costs in Cushing's disease (CD) patients have not been studied extensively. We compared CD patients with diabetes mellitus (DM) patients and population-based controls to characterize differences in utilization and costs. Using 2008-2012 MarketScan® database, we identified three patient groups: (1) CD patients; (2) DM patients; and (3) population-based control patients without CD. DM and control patients were matched to CD patients by age, gender, region, and review year in a 2:1 ratio. Outcomes included annual healthcare resource utilization and costs. There were 1852 CD patients, 3704 DM patients and 3704 controls. Mean age was 42.9 years; 78.2 % were female. CD patients were hospitalized more frequently (19.3 %) than DM patients (11.0 %, p < .001) or controls (5.6 %, p < .001). CD patients visited the ED more frequently (25.4 %) than DM patients (21.1 %, p < .001) or controls (14.3 %, p < .001). CD patients had more office visits than DM patients (19.1 vs. 10.7, p < .001) or controls (7.1, p < .001). CD patients on average filled more prescriptions than DM patients (51.7 vs. 42.7, p < .001) or controls (20.5, p < .001). Mean total healthcare costs for CD patients were $26,269 versus $12,282 for DM patients (p < .001) and $5869 for controls (p < .001). CD patients had significantly higher annual rates of healthcare resource utilization compared to matched DM patients and population controls without CD. CD patient costs were double DM costs and quadruple control costs. This study puts into context the additional burdens of CD over DM, a common, chronic endocrine condition affecting multiple organ systems, and population controls.

Background It is occasionally difficult to distinguish progressive massive fibrosis (PMF) from lung cancer on computed tomography (CT) in patients with pneumoconiosis. Purpose To evaluate the magnetic resonance imaging (MRI) features of PMF and to assess its ability to differentiate PMF from lung cancer. Material and Methods Between 2000 and 2014, 40 pulmonary lesions suspected to be lung cancer on the basis of CT in 28 patients with known pneumoconiosis were evaluated. Twenty-four of the 40 lesions were pathologically or clinically diagnosed as PMF. The signal pattern on T2-weighted (T2W) images, post-contrast enhancement pattern on T1-weighted (T1W) images, and the pattern of the time intensity curve (TIC) on contrast-enhanced dynamic studies were evaluated. All images were analyzed independently by two chest radiologists. Results All 24 PMF lesions showed low signal intensity (SI) on T2W images (sensitivity, 100%), while 15 of 16 lung cancer lesions showed intermediate or high SI on T2W images (specificity, 94%) when PMF was regarded as a positive result. Six of 17 PMF lesions showed a homogeneous enhancement pattern (sensitivity, 35%), and 4/9 lung cancer lesions showed an inhomogeneous or a ring-like enhancement pattern (specificity, 44%). Six of 16 PMF lesions showed a gradually increasing enhancement pattern (sensitivity, 38%), and 7/9 lung cancer lesions showed rapid enhancement pattern (specificity, 78%). Conclusion When differentiation between PMF and lung cancer in patients with pneumoconiosis is difficult on CT, an additional MRI study, particularly the T2W imaging sequence, may help differentiate between the two.

Laparoscopic colectomy is safe and effective in the treatment of many colorectal diseases. However, the effect of increasing use of laparoscopy on overall health care utilization and costs, especially in the long term, has not been thoroughly investigated. To evaluate the effect of laparoscopic vs open colectomy on short- and long-term health care utilization and costs. Retrospective multivariate regression analysis of national health insurance claims data was used to evaluate health care utilization and costs up to 1 year following elective colectomy. Data were obtained from the Truven Health Analytics MarketScan Commercial Claims and Encounters database. Patients aged 18 to 64 years who underwent elective laparoscopic or open colectomy from January 1, 2010, through December 31, 2010, were included. Patients with complex diagnoses that require increased non-surgery-related health care utilization, including malignant neoplasm, inflammatory bowel disease, human immunodeficiency virus, transplantation, and pregnancy, were excluded. Of 25 481 patients who underwent colectomy, 4160 were included in the study. Healthcare utilization, including office, hospital outpatient, and emergency department visits and inpatient services 90 and 365 days after the index procedure; total health care costs; and estimated days off from work owing to health care utilization. Of 25 481 patients who underwent colectomy, 4160 were included in the study (laparoscopic, 45.6%; open, 54.4%). The mean (SD) net and total payments were lower for laparoscopy ($23 064 [$14 558] and $24 196 [$14 507] vs $29 753 [$21 421] and $31 606 [$23 586]). In the first 90 days after surgery, an open approach was significantly associated with a 1.26-fold increase in health care costs (estimated, $1715; 95% CI, $338-$2853), increased use of heath care services, and more estimated days off from work (2.78 days; 95% CI, 1.93-3.59). Similar trends were found in the full postoperative year, with

Full Text Available Karl G Stonecipher,1 Jenny Chia,2 Ahunna Onyenwenyi,2 Linda Villanueva,2 David A Hollander2 1TLC Laser Eye Centers, Greensboro, NC, 2Allergan, Inc., Irvine, CA, USA Background: Dry eye is a multifactorial, symptomatic disease associated with ocular surface inflammation and tear film hyperosmolarity. This study was designed to assess patterns of topical cyclosporine ophthalmic emulsion 0.05% (Restasis® use in dry eye patients and determine if there were any differences in use based on whether dry eye is physician-coded as a primary or nonprimary diagnosis. Methods: Records for adult patients with a diagnosis of dry eye at an outpatient visit from January 1, 2008 to December 31, 2009 were selected from Truven Health MarketScan® Research Databases. The primary endpoint was percentage of patients with at least one primary versus no primary dry eye diagnosis who filled a topical cyclosporine prescription. Data analyzed included utilization of topical corticosteroids, oral tetracyclines, and punctal plugs. Results: The analysis included 576,416 patients, accounting for 875,692 dry eye outpatient visits: 74.7% were female, 64.2% were ages 40-69 years, and 84.4% had at least one primary dry eye diagnosis. During 2008–2009, 15.9% of dry eye patients with a primary diagnosis versus 6.5% with no primary diagnosis filled at least one cyclosporine prescription. For patients who filled at least one prescription, the mean months’ supply of cyclosporine filled over 12 months was 4.44. Overall, 33.9% of dry eye patients filled a prescription for topical cyclosporine, topical corticosteroid, or oral tetracycline over 2 years. Conclusion: Patients with a primary dry eye diagnosis were more likely to fill a topical cyclosporine prescription. Although inflammation is key to the pathophysiology of dry eye, most patients seeing a physician for dry eye may not receive anti-inflammatory therapies.

Objective To determine whether utilization of emergency medical service (EMS) can expedite and improve the rate of thrombolytic therapy administration in acute ischemic stroke patients. Methods This is a prospective observational study of consecutive patients presenting to the emergency department (ED) with an ischemic stroke within 72 hours of symptom onset. Variables associated with early ED arrival (within 3 hours of stroke onset), and administration of thrombolytic therapy were analyzed. We also evaluated the factors related to onset-to-needle time in patients receiving thrombolytic therapy. Results From January 1, 2010 to July 31, 2011, there were 1081 patients (62.3% men, age 69.6 ± 13 years) included in this study. Among them, 289 (26.7%) arrived in the ED within 3 hours, and 88 (8.1%) received intravenous thrombolytic therapy. Patients who arrived to the ED by EMS (n=279, 25.8 %) were independently associated with earlier ED arrival (adjusted odds ratio [OR] = 3.68, 95% confidence interval [CI] = 2.54 to 5.33), and higher chance of receiving thrombolytic therapy (adjusted OR = 3.89, 95% CI= 1.86 to 8.17). Furthermore, utilization of EMS decreased onset-to-needle time by 26 minutes in patients receiving thrombolytic therapy. Conclusion Utilization of EMS can help acute ischemic stroke patients in early presentation to ED, facilitate thrombolytic therapy, and reduce the onset to needle time. PMID:24296308

  This study was designed to describe burden of illness and treatment patterns, and to examine the patient, physician, and care factors associated with the treatment choices of individuals receiving new prescriptions for fibromyalgia (FM).   This is a baseline assessment of the Real-World Examination of Fibromyalgia: Longitudinal Evaluation of Costs and Treatments (REFLECTIONS), a prospective observational study. Baseline data (including a physician survey, a patient visit form, and computer-assisted telephone interviews) were collected from July 2008 through May 2010 in 58 care settings in the United States, including Puerto Rico.   Patients (N = 1,700) were mostly female (94.6%) and white (82.9%). Mean age was 50.4 years and mean duration of illness was 5.6 years. Mean Fibromyalgia Impact Questionnaire total score was 54.4 (range 0-80), and Brief Pain Inventory average pain severity level was 5.5 (range 0-10). Patients reported high annual health care use and numerous work limitations related to FM. Patients were taking 182 unique types of medications prescribed for FM, including duloxetine (26.8%), nonsteroidal anti-inflammatory drugs (26.6%), pregabalin (24.5%), opioids (24.2%), tramadol (15.3%), benzodiazepines (15.2%), cyclobenzaprine (12.9%), milnacipran (8.9%), and others. Most patients took more than one medication concurrently (77.8%). Type of current medications used was most strongly associated with medication history and physician specialty.   Burden of illness was high for patients with FM, and treatment patterns were highly variable. Importantly, the treatments with the most evidence to support their use were not always the most frequently chosen. Wiley Periodicals, Inc.

To define the patterns of Internet use among physicians who treat inflammatory bowel disease (IBD) and physicians' perceptions of their patients' Internet use. An online survey about physician and patient use of the Internet was created and e-mailed to gastroenterologists nationwide. Surveys were distributed and collected via an online database and a subsequent statistical analysis was performed. Of the 1000 e-mail invitations sent to practicing gastroenterologists in the United States, 223 participants (22.3%) completed the survey. A total of 183 (82.1%) physicians reported using an Internet-based reference to assist them in deriving management strategies for their patients with IBD, with the most commonly utilized resource being UpToDate followed by PubMed and the Crohn's and Colitis Foundation of America Web site. Although nearly 80% of gastroenterologists believed that using the Internet helped them facilitate clinical discussions, 183 participants (82.1%) believed that inaccurate information found online could sometimes result in increased clinic time because physicians must spend more time dispelling misleading information. Despite a study design biased toward selecting gastroenterologists who commonly used the Internet, we demonstrated that only 60% of the providers routinely refer their patients to the Internet. This underscores the fact that it is important to have a centralized "physician-certified" online resource to which physicians could readily refer their patients to navigate through various disease-specific resources without concern that their patients are receiving unreliable or misleading information.

Background Cardiac rehabilitation (CR) societies recommend assessment of patient satisfaction given its association with health care utilization and outcomes. Recently, the Patient Assessment of Chronic Illness Care (PACIC, Glasgow) was recommended as an appropriate tool for the CR setting. The objectives of this study were to 1) describe patient satisfaction with CR, 2) test the psychometric properties of the PACIC in the CR setting, and 3) assess the association of patient satisfaction with CR utilization and outcomes. Methods Secondary analysis was conducted on an observational, prospective CR program evaluation cohort. A convenience sample of patients from 1 of 3 CR programs was approached at their first CR visit, and consenting participants completed a survey. Clinical data were extracted from charts pre- and post-program. Participants were e-mailed surveys again 6 months (including the PACIC) and 1 and 2 years later. Results Of 411 consenting patients, 247 (60.2%) completed CR. The mean PACIC score was 2.8±1.1/5. Internal reliability was α=0.95. The total PACIC score varied significantly by site (F=3.12, P=0.046), indicating discriminant validity. Patient satisfaction was significantly related to greater CR adherence (r=0.22, Ppatient satisfaction with CR. PMID:28479853

  The high prevalence of persistent low back pain and growing number of diagnostic and therapeutic modalities employed to manage chronic low back pain and the subsequent impact on society and the economy continue to hold sway over health care policy. Among the multiple causes responsible for chronic low back pain, the contributions of the sacroiliac joint have been a subject of debate albeit a paucity of research. At present, there are no definitive conservative, interventional or surgical management options for managing sacroiliac joint pain. It has been shown that the increases were highest for facet joint interventions and sacroiliac joint blocks with an increase of 310% per 100,000 Medicare beneficiaries from 2000 to 2011. There has not been a systematic assessment of the utilization and growth patterns of sacroiliac joint injections. Analysis of the growth patterns of sacroiliac joint injections in Medicare beneficiaries from 2000 to 2011. To evaluate the utilization and growth patterns of sacroiliac joint injections. This assessment was performed utilizing Centers for Medicare and Medicaid Services (CMS) Physician/Supplier Procedure Summary (PSPS) Master data from 2000 to 2011. The findings of this assessment in Medicare beneficiaries from 2000 to 2011 showed a 331% increase per 100,000 Medicare beneficiaries with an annual increase of 14.2%, compared to an increase in the Medicare population of 23% or annual increase of 1.9%. The number of procedures increased from 49,554 in 2000 to 252,654 in 2011, or a rate of 125 to 539 per 100,000 Medicare beneficiaries. Among the various specialists performing sacroiliac joint injections, physicians specializing in physical medicine and rehabilitation have shown the most increase, followed by neurology with 1,568% and 698%, even though many physicians from both specialties have been enrolling in interventional pain management and pain management.

Patients with advanced cancer often experience frequent and prolonged hospitalizations; however, the factors associated with greater health care utilization have not been described. We sought to investigate the relation between patients' physical and psychological symptom burden and health care utilization. We enrolled patients with advanced cancer and unplanned hospitalizations from September 2014-May 2016. Upon admission, we assessed physical (Edmonton Symptom Assessment System [ESAS]) and psychological symptoms (Patient Health Questionnaire 4 [PHQ-4]). We examined the relationship between symptom burden and healthcare utilization using linear regression for hospital length of stay (LOS) and Cox regression for time to first unplanned readmission within 90 days. We adjusted all models for age, sex, marital status, comorbidity, education, time since advanced cancer diagnosis, and cancer type. We enrolled 1,036 of 1,152 (89.9%) consecutive patients approached. Over one-half reported moderate/severe fatigue, poor well being, drowsiness, pain, and lack of appetite. PHQ-4 scores indicated that 28.8% and 28.0% of patients had depression and anxiety symptoms, respectively. The mean hospital LOS was 6.3 days, and the 90-day readmission rate was 43.1%. Physical symptoms (ESAS: unstandardized coefficient [B], 0.06; P cancer experience a high symptom burden, which is significantly associated with prolonged hospitalizations and readmissions. Interventions are needed to address the symptom burden of this population to improve health care delivery and utilization.

Background Opioids are widely accepted as treatment for moderate to severe pain, and opioid-induced constipation is one of the most common side effects of opioids. This side effect negatively affects pain management and patients’ quality of life, which could result in increased healthcare utilization and costs. Objective To assess healthcare utilization and costs (all-cause, constipation-related, and pain-related) for individuals with and without opioid-induced constipation during the 12 months after initiation of opioid therapy for noncancer pain. Methods This retrospective cohort study was conducted using administrative claims data from HealthCore Integrated Research Environment between January 1, 2006, and June 30, 2014. The analysis was limited to patients aged ≥18 years who filled a prescription for continuous opioid treatment (≥28 days) for noncancer pain. Propensity scores were used to match opioid users with constipation (cohort 1) and opioid users without constipation (cohort 2), using a 1:1 ratio. Generalized linear models were used to estimate all-cause, constipation-related, and pain-related healthcare utilization and costs during the 12 months after the initiation of opioid therapy. Results After matching and balancing for all prespecified variables, 17,384 patients were retained in each cohort (mean age, 56 years; 63% female). Opioid users with constipation were twice as likely as those without constipation to have ≥1 inpatient hospitalizations (odds ratio, 2.28; 95% confidence interval [CI], 2.17–2.39) during the 12 months. The total mean adjusted overall costs per patient during the study period were $12,413 higher for patients with constipation versus those without it (95% CI, $11,726–$13,116). The total mean adjusted overall pain-related costs per patient were $6778 (95% CI, $6293–$7279) higher for the patients with constipation than those without. Among patients using opioids for noncancer pain, the annual mean constipation

To analyze the utilization and fractionation of extreme hypofractionation via stereotactic body radiotherapy (SBRT) in the treatment of prostate cancer. Data was analyzed on men diagnosed with localized prostate cancer between 2004–2012 and treated with definitive-intent radiation therapy, as captured in the National Cancer Database. This database is a hospital-based registry that collects an estimated 70% of all diagnosed malignancies in the United States. There were 299,186 patients identified, of which 4,962 (1.7%) were identified as receiving SBRT as primary treatment. Of those men, 2,082 had low risk disease (42.0%), 2,201 had intermediate risk disease (44.4%), and 679 had high risk disease (13.7%). The relative utilization of SBRT increased from 0.1% in 2004 to 4.0% in 2012. Initially SBRT was more commonly used in academic programs, though as time progressed there was a shift to favor an increased absolute number of men treated in the community setting. Delivery of five separate treatments was the most commonly utilized fractionation pattern, with 4,635 patients (91.3%) receiving this number of treatments. The most common dosing pattern was 725 cGy × 5 fractions (49.6%) followed by 700 cGy × 5 fractions (21.3%). Extreme hypofractionation via SBRT is slowly increasing acceptance. Currently 700-725 cGy × 5 fractions appears to be the most commonly employed scheme. As further long-term data regarding the safety and efficacy emerges, the relative utilization of this modality is expected to continue to increase

High blood pressure causes left ventricular hypertrophy, which is a negative prognostic factor among hypertensive patients. To assess left ventricular geometric remodeling patterns in patients with essential hypertension or with hypertension secondary to parenchymal renal disease. We analyzed data from echocardiograms performed in 250 patients with essential hypertension (150 females) and 100 patients with secondary hypertension (60 females). The interventricular septum and the left ventricular posterior wall thickness were measured in the parasternal long-axis. Left ventricular mass was calculated using the Devereaux formula. The most common remodeling type in females and males with essential hypertension were eccentric and concentric left ventricular hypertrophy (cLVH), respectively. Among patients with secondary arterial hypertension, cLVH was most commonly observed in both genders. The prevalence of left ventricular hypertrophy was higher among patients with secondary hypertension. The left ventricular mass index and the relative left ventricular wall thickness were higher in males and also in the secondary hypertension group. Age, blood pressure values and the duration of hypertension, influenced remodeling patterns. We documented a higher prevalence of LVH among patients with secondary hypertension. The type of ventricular remodeling depends on gender, age, type of hypertension, blood pressure values and the duration of hypertension.

Interpretation of gait data obtained from modern 3D gait analysis is a challenging and time consuming task. The aim of this study was to create neural network models which can recognise the gait patterns from pre- and post-treatment and the normal ones. Neural network is a method which works on the principle of learning from experience and then uses the obtained knowledge to predict the unknown. Methods: Twenty-eight patients with cerebral palsy were recruited as subjects whose gait was analysed in pre- and post-treatment. A group of twenty-six normal subjects also participated in this study as control group. All subjects gait was analysed using Vicon Nexus to obtain the gait parameters and kinetic and kinematic parameters of hip, knee and ankle joints in three planes of both limbs. The gait data was used as input to create neural network models. A total of approximately 300 trials were split into 70% and 30% to train and test the models, respectively. Different models were built using different parameters. The gait was categorised as three patterns, i.e., normal, pre- and post-treatments. Result: The results showed that the models using all parameters or using the joint angles and moments could predict the gait patterns with approximately 95% accuracy. Some of the models e.g., the models using joint power and moments, had lower rate in recognition of gait patterns with approximately 70-90% successful ratio. Conclusion: Neural network model can be used in clinical practice to recognise the gait pattern for cerebral palsy patients. (author)

Considerable attention has been paid to the rising costs of the use of blood glucose test strips (BGTS). Insulin users have generally been treated as a single homogeneous group, resulting in policies that cap usage (8.2 strips/day) in provincial drug insurance programs. The objective of this study was to conduct a utilization review of BGTS by insulin users and to evaluate use patterns against current insulin use patterns and BGTS policy. BGTS usage was examined in a cohort of insulin users with type 1 and type 2 diabetes over a 12-year period (2001 to 2013) using the population-based administrative data in Manitoba, Canada. Total BGTS strip use increased by 121%, from $4.3 to $9.5 million. However, the number of insulin users also increased by 115%. Use has been stable at 1.5 strips per day per person since 2004 by insulin users with type 2 diabetes but has risen from 1.9 to 3.0 strips per day per person in those with type 1 diabetes. Mean daily test strip use was below the number of daily tests recommended for patients using insulin as per the current Canadian guidelines, with 11% and 15% of insulin users with type 1 and type 2 diabetes not claiming any BGTS use and a further 15% (type 1) and 28% (type 2) using fewer than 1 strip per day. BGTS use per insulin user has been stable for most of the past decade, and the vast majority of use falls well below provincial insurance caps. The amount of low-level testing (0 to <1 strip/day) suggests that greater attention should be directed to ensuring a safe level of testing by all insulin users. Copyright © 2017 The Authors.

The AHRQ Patient Safety Indicators (PSIs) are used for calculation of risk-adjusted postoperative rates for adverse events. The payers and quality consortiums are increasingly requiring public reporting of hospital performance on these metrics. We discuss processes designed to improve the accuracy and clinical utility of PSI reporting in practice. The study was conducted at a 793-bed tertiary care academic medical center where PSI processes have been aggressively implemented to track patient safety events at discharge. A three-phased approach to improving administrative data quality was implemented. The initiative consisted of clinical review of all PSIs, documentation improvement, and provider outreach including active querying for patient safety events. This multidisciplinary effort to develop a streamlined process for PSI calculation reduced the reporting of miscoded PSIs and increased the clinical utility of PSI monitoring. Over 4 quarters, 4 of 41 (10%) PSI-11 and 9 of 138 (7%) PSI-15 errors were identified on review of clinical documentation and appropriate adjustments were made. A multidisciplinary, phased approach leveraging existing billing infrastructure for robust metric coding, ongoing clinical review, and frontline provider outreach is a novel and effective way to reduce the reporting of false-positive outcomes and improve the clinical utility of PSIs.

Expert guidelines recommend non-pharmacologic treatments and non-opioid medications for chronic pain and recommend against initiating long-term opioid therapy (LTOT). We examined whether veterans with incident chronic pain receiving care at facilities with greater utilization of non-pharmacologic treatments and non-opioid medications are less likely to initiate LTOT. Retrospective cohort study PARTICIPANTS: Veterans receiving primary care from a Veterans Health Administration facility with incident chronic pain between 1/1/2010 and 12/31/2015 based on either of 2 criteria: (1) persistent moderate-to-severe patient-reported pain and (2) diagnoses "likely to represent" chronic pain. The independent variable was facility-level utilization of pain-related treatment modalities (non-pharmacologic, non-opioid medications, LTOT) in the prior calendar year. The dependent variable was patient-level initiation of LTOT (≥ 90 days within 365 days) in the subsequent year, adjusting for patient characteristics. Among 1,094,569 veterans with incident chronic pain from 2010 to 2015, there was wide facility-level variation in utilization of 10 pain-related treatment modalities, including initiation of LTOT (median, 16%; range, 5-32%). Veterans receiving care at facilities with greater utilization of non-pharmacologic treatments were less likely to initiate LTOT in the year following incident chronic pain. Conversely, veterans receiving care at facilities with greater non-opioid and opioid medication utilization were more likely to initiate LTOT; this association was strongest for past year facility-level LTOT initiation (adjusted rate ratio, 2.10; 95% confidence interval, 2.06-2.15, top vs. bottom quartile of facility-level LTOT initiation in prior calendar year). Facility-level utilization patterns of non-pharmacologic, non-opioid, and opioid treatments for chronic pain are associated with subsequent patient-level initiation of LTOT among veterans with incident chronic pain

Although colorectal cancer (CRC) screening guidelines recommend initiating screening at age 50 years, the percentage of cancer cases in younger patients is increasing. To the authors' knowledge, the national treatment patterns and outcomes of these patients are largely unknown. The current study was a population-based, retrospective cohort study of the nationally representative Surveillance, Epidemiology, and End Results registry for patients diagnosed with CRC from 1998 through 2011. Patients were categorized as being younger or older than the recommended screening age. Differences with regard to stage of disease at diagnosis, patterns of therapy, and disease-specific survival were compared between age groups using multinomial regression, multiple regression, Cox proportional hazards regression, and Weibull survival analysis. Of 258,024 patients with CRC, 37,847 (15%) were aged Cancer Society.

Aims of the study were to describe behavioral health treatment utilization patterns of community-dwelling older adults with depressive symptoms over a six-month period and to identify factors associated with treatment use, guided by a theoretical model emphasizing the dynamic nature of treatment use patterns over time and social context. A total of 144 participants ≥65 years old with depressive symptoms completed an in-person baseline interview and six monthly telephone follow-up interviews. Outcomes at each follow-up included the use of antidepressants or counseling. Covariates included personal and social context variables. Approximately half of the participants (N=70, 48%) received no formal treatment (antidepressant prescription or counseling). Treatment use or nonuse did not change for most participants. More participants with severe symptoms received antidepressants (25%-37%) than did those with milder symptoms (10%-14%), although more participants in the latter group started (milder, 62%,versus severe, 49%) and stopped (milder, 77%, versus severe, 26%) antidepressant treatment at least once. Fewer individuals received counseling overall, with no clear patterns by symptom severity. In multivariate longitudinal analyses, treatment use at follow-up was independently associated with younger age, current major depressive episode, baseline use of antidepressant, intention to begin a new treatment at baseline, and receipt of advice to seek treatment. Over a six-month period, most older adults with depressive symptoms in this study continued their use or nonuse of mental health treatment. Demographic, need, attitudinal, and social variables were related to treatment use over time. Addressing intentions and providing advice may facilitate treatment seeking.

Full Text Available Introduction: The increasing rate of patient exposure to radiation from computerized tomography (CT raises questions about appropriateness of utilization. There is no current standard to employ informed consent for CT (ICCT. Our study assessed the relationship between informed consent and CT utilization in emergency department (ED patients. Methods: An observational multiphase before-after cohort study was completed from 4/2010-5/2011. We assessed CT utilization before and after (Time I/ Time II the implementation of an informed consent protocol. Adult patients were included if they presented with symptoms of abdominal/pelvic pathology or completed ED CT. We excluded patients with pregnancy, trauma, or altered mental status. Data on history, exam, diagnostics, and disposition were collected via standard abstraction tool. We generated a multivariate logistic model via stepwise regression, to assess CT utilization across risk groups. Logistic models, stratified by risk, were generated to include study phase and a propensity score that controlled for potential confounders of CT utilization. Results: 7,684 patients met inclusion criteria. In PHASE 2, there was a 24% (95% CI [10-36%] reduction in CT utilization in the low-risk patient group (p<0.002. ICCT did not affect CT utilization in the high-risk group (p=0.16. In low-risk patients, the propensity score was significant (p<0.001. There were no adverse events reported during the study period. Conclusion: The implementation of ICCT was associated with reduced CT utilization in low-risk ED patients. ICCT has the potential to increase informed, shared decision making with patients, as well as to reduce the risks and cost associated with CT.

Context Patient demographic and clinical factors have known associations with acute health care utilization (AHCU) among patients with sickle cell disease (SCD), but it is unknown if pain measured predominantly in an outpatient setting is a predictor of future AHCU in patients with SCD. Objectives To determine whether multidimensional pain scores obtained predominantly in an outpatient setting predicted subsequent one-year AHCU by 137 adults with SCD and whether the pain measured at a second visit also predicted AHCU. Methods Pain data included the Composite Pain Index (CPI), a single score representative of a multidimensional pain experience (number of pain sites, intensity, quality, and pattern). Based on the distribution of AHCU events, we divided patients into three groups: (1) zero events (Zero), (2) 1–3 events (Low), or (3) 4–23 events (High). Results The initial CPI scores differed significantly by the three groups (F(2,134)=7.38, P=0.001). Post hoc comparisons showed that the Zero group had lower CPI scores than both the Low group (Pgroup (Page, and CPI scores (at both measurement times) were statistically significant predictors of utilization events. Pain intensity scores at both measurement times were significant predictors of utilization, but other pain scores (number of pain sites, quality, and pattern) were not. Conclusion Findings support use of outpatient CPI scores or pain intensity and age to identify at-risk young adults with SCD who are likely to benefit from improved outpatient pain management plans.

Full Text Available Rehabilitation plays an important role in the physical health of patients with hemophilia. However, comprehensive information regarding the utilization of rehabilitation for such patients remains scarce.This population-based study aimed to examine the characteristics, trends, and most important factors affecting rehabilitation usage in patients with hemophilia A using a nationwide database in Taiwan.Data from 777 patients with hemophilia A who were registered in the National Health Insurance Research Database between 1998 and 2008 were analyzed using SAS 9.0.Musculoskeletal or nervous system-related surgical procedures and clotting factor VIII concentrate costs were identified as factors affecting rehabilitation usage; musculoskeletal or nervous system-related surgical procedures (odds ratio = 3.788; P < 0.001 were the most important predictor of whether a patient with hemophilia A would use rehabilitation services. Joint disorders, arthropathies, bone and cartilage disorders, intracranial hemorrhage, and brain trauma were common diagnoses during rehabilitation use. The costs of physical therapy (physiotherapy comprised the majority (71.2% of rehabilitation therapy categories. Increasingly, rehabilitation therapy was performed at physician clinics. The total rehabilitation costs were <0.1% of the total annual medical costs.Musculoskeletal or nervous system-related surgical procedures and increased use of clotting factor VIII concentrate affect the rehabilitation utilization of patients with hemophilia A the most. The findings in this study could help clinicians comprehensively understand the rehabilitation utilization of patients with hemophilia A.

To investigate the clinical feature and the local failure patterns after intensity-modulated radiotherapy for nasopharyngeal carcinoma. Between March 2007 and July 2009, 710 patients with nasopharyngeal carcinoma were treated with intensity-modulated radiotherapy. The magnetic resonance imagings obtained at recurrence were registered with the original planning computed tomography for dosimetry analysis. With a median follow-up of 38 months, 34 patients have developed local recurrence (32 cases valid). The incidence of invasion to nasopharynx, parapharyngeal space and the retropharyngeal space by the primary tumors was 100%, 75.0% and 62.5%, respectively, but 78.1%, 34.4% and 21.9% at recurrence, respectively. The rate of invasion to ethmoid sinus was 3.1% by the primary tumors but 28.1% at recurrence (p = 0.005). The topographic analysis of the local failure patterns showed 'central' in 16 patients; 'marginal' in 9; and 'outside' in 7. The median volumes of primary gross tumor were 45.84 cm 3 in the central failure group, 29.44 cm 3 in the marginal failure group, and 21.52 cm 3 in the outside failure group, respectively (p = 0.012), and the median volumes of primary clinical target1 were 87.28 cm 3 , 61.90 cm 3 and 58.74 cm 3 in the three groups, respectively (p = 0.033). In patients with nasopharyngeal carcinoma treated with intensity-modulated radiotherapy, the recurrent tumors had their unique characteristic and regularity of invasion to adjacent structures. 'Central' failure was the major local failure pattern. The volumes of primary gross tumor and clinical target1 were significantly correlated with recurrent patterns. Employ more aggressive approaches to tumor cells which will be insensitive to radiotherapy may be an effective way to reduce the central failure

Exploring the Patterns and Mechanisms of Reclaimed Arable Land Utilization under the Requisition-Compensation Balance Policy in Wenzhou, China

2017-12-01

Full Text Available Arable land in China is undergoing significant changes, with massive losses of arable land due to rapid urbanization and the reclamation of arable land from other lands to compensate for these losses. Many studies have analyzed arable land loss, but less attention has been paid to land reclamation, and the utilization of reclaimed land remains unclear. The goal of our study was to characterize the patterns and efficiency of the utilization of reclaimed land and to identify the factors influencing the land utilization process in Wenzhou using remote sensing, geographic information systems and logistic regression. Our results showed that only 37% of the total reclaimed land area was under cultivation, and other lands were still bare or had been covered by trees and grasses. The likelihood that reclaimed land was used for cultivation was highly correlated with the land use type of its neighboring or adjacent parcels. Reclaimed land utilization was also limited at high elevations in lands with poor soil fertility and in lands at a great distance from rural residential areas. In addition, parcels located in the ecological protection zone were less likely to be cultivated. Therefore, we suggest that the important determinants should be considered when identifying the most suitable land reclamation areas.

Full Text Available Context: In medical and veterinary medical education the use of problem-based and cased-based learning has steadily increased over time. At veterinary faculties, this development has mainly been evident in the clinical phase of the veterinary education. Therefore, a consortium of teachers of biochemistry and physiology together with technical and didactical experts launched the EU-funded project “vetVIP”, to create and implement veterinary virtual patients and problems for basic science instruction. In this study the implementation and utilization of virtual patients occurred at the veterinary faculties in Budapest, Hannover and Lublin.Methods: This report describes the investigation of the utilization and acceptance of students studying veterinary basic sciences using optional online learning material concurrently to regular biochemistry and physiology didactic instruction. The reaction of students towards this offer of clinical case-based learning in basic sciences was analysed using quantitative and qualitative data. Quantitative data were collected automatically within the chosen software-system CASUS as user-log-files. Responses regarding the quality of the virtual patients were obtained using an online questionnaire. Furthermore, subjective evaluation by authors was performed using a focus group discussion and an online questionnaire.Results: Implementation as well as usage and acceptance varied between the three participating locations. High approval was documented in Hannover and Lublin based upon the high proportion of voluntary students (>70% using optional virtual patients. However, in Budapest the participation rate was below 1%. Due to utilization, students seem to prefer virtual patients and problems created in their native language and developed at their own university. In addition, the statement that assessment drives learning was supported by the observation that peak utilization was just prior to summative examinations

We surveyed 150 methadone maintenance treatment program (MMTP) patients about pain, pain treatment utilization, perceived efficacy of prior pain treatment, and interest in pursuing pain treatment at the MMTP. Respondents with chronic severe pain (CSP) (ie, pain lasting at least six months with moderate to severe pain intensity or significant pain interference) and "some pain" (ie, pain reported in the previous week but not CSP) endorsed similar rates of past-week and lifetime allopathic or standard medical (with the exception of lifetime medical use of non-opiate medication) and complementary and alternative medicine (CAM) utilization for pain reduction. Prior pain treatments were perceived to be less effective by CSP than SP patients but both groups had equivalent high rates of interest in pain treatment associated with the MMTP. These findings may have implications for resource and program planning in MMTPs.

Highlights: ► PCNSL are rare but highly malignant brain tumors. ► PCNSL recur in different anatomic sites compared with initial presentation. ► Non-parenchymal contrast enhancement is a frequent finding at initialdiagnosis and at relapse. -- Abstract: Purpose: Primary CNS lymphomas (PCNSL) are highly malignant non-Hodgkin's B-cell lymphoma restricted to the CNS. While MRI features of PCNSL at initial presentation have been comprehensively described, literature on MRI-characteristics at relapse is sparse. The purpose of this study was to investigate anatomic location and contrast enhancement patterns at PCNSL recurrence by cranial MRI. Methods: Sixteen immunocompetent patients (9 men, 7 women, median age 65 years) with histologically proven PCNSL and initial response to a standardized polychemotherapy, but suffering from a relapse were consecutively recorded. Native and contrast-enhanced MRI examinations carried out at initial presentation and at time of relapse were compared. Anatomical site of parenchymal enhancement, frequency and presence of non-parenchymal contrast enhancement (i.e. ventricular, superficial, subependymal) patterns at initial presentation and at relapse were recorded and compared. Results: Local recurrence was found at the site of the initial tumor presentation in four of the 16 cases. Six of 11 patients presenting a unilateral PCNSL at initial presentation had a bilateral involvement at relapse. In two cases, recurrence appeared solely on the contralateral side without involvement of the hemisphere initially affected. At both dates, subependymal enhancement was the most often found non-parenchymal pattern (six at initial presentation, and five at relapse). The number of patients with a ventricular contrast enhancement increased from one at initial presentation to four at relapse. Conclusions: PCNSL tend to recur in different parenchymal anatomic sites as compared with the site of the initial tumor presentation. Contrast-enhancing non

Nonconvulsive status epilepticus (NCSE) is common in patients with coma with a prevalence between 5% and 48%. Patients in deep coma may exhibit epileptiform EEG patterns, such as generalized periodic spikes, and there is an ongoing debate about the relationship of these patterns and NCSE. The purposes of this review are (i) to discuss the various EEG patterns found in coma, its fluctuations, and transitions and (ii) to propose modified criteria for NCSE in coma. Classical coma patterns such as diffuse polymorphic delta activity, spindle coma, alpha/theta coma, low output voltage, or burst suppression do not reflect NCSE. Any ictal patterns with a typical spatiotemporal evolution or epileptiform discharges faster than 2.5 Hz in a comatose patient reflect nonconvulsive seizures or NCSE and should be treated. Generalized periodic diacharges or lateralized periodic discharges (GPDs/LPDs) with a frequency of less than 2.5 Hz or rhythmic discharges (RDs) faster than 0.5 Hz are the borderland of NCSE in coma. In these cases, at least one of the additional criteria is needed to diagnose NCSE (a) subtle clinical ictal phenomena, (b) typical spatiotemporal evolution, or (c) response to antiepileptic drug treatment. There is currently no consensus about how long these patterns must be present to qualify for NCSE, and the distinction from nonconvulsive seizures in patients with critical illness or in comatose patients seems arbitrary. The Salzburg Consensus Criteria for NCSE [1] have been modified according to the Standardized Terminology of the American Clinical Neurophysiology Society [2] and validated in three different cohorts, with a sensitivity of 97.2%, a specificity of 95.9%, and a diagnostic accuracy of 96.3% in patients with clinical signs of NCSE. Their diagnostic utility in different cohorts with patients in deep coma has to be studied in the future. This article is part of a Special Issue entitled "Status Epilepticus". Copyright © 2015.

Inappropriate shocks (IASs) from implantable cardioverter defibrillators (ICDs) are associated with decreased quality of life, but whether they increase healthcare utilization and treatment costs is unknown. We sought to determine the impact of IASs on subsequent healthcare utilization and treatment costs. We conducted a case-control analysis of ICD patients at a single institution from 1997 to 2010 and who had ≥12 months of post-ICD implant follow-up. Cases included all patients experiencing an IAS during the first 12 months after implantation. Eligible control patients did not receive a shock of any kind during the 12 months after implantation. Propensity scores based on 36 covariates (area under curve = 0.78) were used to match cases to controls. We compared the rate (occurrences/person year [PY]) of healthcare utilization immediately following IAS to the end of the 12-month follow-up period to the rate in the no-shock group over 12 months of follow-up. We also compared 12-month postimplant treatment (outpatient clinic, emergency room, and hospitalization) costs in both groups. A total of 76 patients experiencing ≥1 IAS during the first 12 months after implant (contributing 48 PYs) were matched to 76 no-shock patients (contributing 76 PYs). Cardiovascular (CV)-related clinic visit and hospitalization rates were increased following an IAS compared to those not receiving a shock (4.0 vs 3.3 and 0.7 vs 0.5, respectively, P = 0.02 for both). CV-related emergency room visitation (0.15 vs 0.08) rates were also numerically higher following an IAS, but did not reach statistical significance (P = 0.26). Patients experiencing an IAS accrued greater treatment costs during the 12 months postimplant compared to no-shock patients ($13,973 ± $46,345 vs $6,790 ± $19,091, P = 0.001). Recipients of IAS utilize the healthcare system more frequently following an IAS than patients not experiencing a shock. This increased utilization results in higher costs of treating IAS

Full Text Available Abstract Background It is commonly stated that nerve root pain should be expected to follow a specific dermatome and that this information is useful to make the diagnosis of radiculopathy. There is little evidence in the literature that confirms or denies this statement. The purpose of this study is to describe and discuss the diagnostic utility of the distribution of pain in patients with cervical and lumbar radicular pain. Methods Pain drawings and descriptions were assessed in consecutive patients diagnosed with cervical or lumbar nerve root pain. These findings were compared with accepted dermatome maps to determine whether they tended to follow along the involved nerve root's dermatome. Results Two hundred twenty-six nerve roots in 169 patients were assessed. Overall, pain related to cervical nerve roots was non-dermatomal in over two-thirds (69.7% of cases. In the lumbar spine, the pain was non-dermatomal in just under two-thirds (64.1% of cases. The majority of nerve root levels involved non-dermatomal pain patterns except C4 (60.0% dermatomal and S1 (64.9% dermatomal. The sensitivity (SE and specificity (SP for dermatomal pattern of pain are low for all nerve root levels with the exception of the C4 level (Se 0.60, Sp 0.72 and S1 level (Se 0.65, Sp 0.80, although in the case of the C4 level, the number of subjects was small (n = 5. Conclusion In most cases nerve root pain should not be expected to follow along a specific dermatome, and a dermatomal distribution of pain is not a useful historical factor in the diagnosis of radicular pain. The possible exception to this is the S1 nerve root, in which the pain does commonly follow the S1 dermatome.

Histoplasmosis has attained increasing relevance in the past 3 decades because of the appearance of the human immunodeficiency virus (HIV). In most immunocompetent persons, the infection is asymptomatic or can produce a respiratory condition with symptoms and radiological images similar to those observed in pulmonary tuberculosis; in non-HIV+ immunocompromised patients, it can cause respiratory symptoms or evolve into a disseminated infection. The same can occur in acquired immunodeficiency syndrome (AIDS) patients. We have observed a series of HIV+ patients with AIDS who presented with cutaneous histoplasmosis and in whom the clinical and histopathological features were highly unusual, including variable mucocutaneous lesions that were difficult to diagnose clinically. These patients displayed unusual, previously undescribed, histological patterns, including lichenoid pattern, nodular pseudomyxoid pattern, pyogenic granuloma-like pattern, perifollicular pattern, and superficial (S), mid (M), and deep perivascular dermatitis; and more commonly encountered patterns, such as histiocytic lobular panniculitis and focal nodular dermatitis. The novel histopathological patterns of cutaneous involvement by histoplasmosis seen in these patients resembled other common inflammatory and infectious conditions and required a high level of suspicion and the application of special stains for organisms for confirmation. These new, clinical, and histological findings do not seem to be commonly encountered in HIV- patients infected with the fungus but seem to be displayed most prominently in HIV+ patients with AIDS.

Despite the high prevalence and impact of episodic breathlessness, information about characteristics and patterns is scarce. To explore the experience of patients with advanced disease suffering from episodic breathlessness, in order to describe types and patterns. Qualitative design using in-depth interviews with patients suffering from advanced stages of chronic heart failure, chronic obstructive pulmonary disease, lung cancer or motor neurone disease. As part of the interviews, patients were asked to draw a graph to illustrate typical patterns of breathlessness episodes. Interviews were tape-recorded, transcribed verbatim and analysed using Framework Analysis. The graphs were grouped according to their patterns. Fifty-one participants (15 chronic heart failure, 14 chronic obstructive pulmonary disease, 13 lung cancer and 9 motor neurone disease) were included (mean age 68.2 years, 30 of 51 men, mean Karnofsky 63.1, mean breathlessness intensity 3.2 of 10). Five different types of episodic breathlessness were described: triggered with normal level of breathlessness, triggered with predictable response (always related to trigger level, e.g. slight exertion causes severe breathlessness), triggered with unpredictable response (not related to trigger level), non-triggered attack-like (quick onset, often severe) and wave-like (triggered or non-triggered, gradual onset). Four patterns of episodic breathlessness could be identified based on the graphs with differences regarding onset and recovery of episodes. These did not correspond with the types of breathlessness described before. Patients with advanced disease experience clearly distinguishable types and patterns of episodic breathlessness. The understanding of these will help clinicians to tailor specific management strategies for patients who suffer from episodes of breathlessness.

Full Text Available Objective: The purposes of this study were to evaluate to study soft tissue facial profile among the different vertical patterns using the Holdaway analysis and the soft tissue thickness measurements. Materials and Methods: The study sample consisted of 90 patients divided into 3 groups: low angle group (30 patients; mean age, 20.38±3.76 years, normal angle group (30 patients; mean age, 19.36±2.83 years and high angle group (30 patients; mean age, 19.44±2.14 years. The study sample, comprised a total of 90 patients (54 women and 36 men divided into low-angle, normal-angle and high angle groups based on vertical growth pattern using the SN/GoGn angle (high-angle group >37°; low-angle group <27°; and control group or normal angle group 27-37°. Facial soft-tissue thickness and Holdaway measurements were analyzed on each radiograph with Image J programme. One-way analysis of variance and post-hoc test (Tukey were used to compare Holdaway measurements and soft tissue thicknesses among the three groups. Results: Significant differences among vertical patterns were observed for the ‘gnathion’, ‘menton’, ‘stomion’ and ‘inferior sulcus to H line’ when both genders were combined. These measurements were thinner in the high-angle group. Significant differences among vertical patterns were observed for ‘gnathion’ and ‘lower lip to H line’ in women; for ‘stomion’ and ‘nose prominence’ in men when examined separately. Conclusion: Facial soft tissue measurements except some for in high angle group were thinner than in low angle group. All soft tissue measurements were greater except for gnathion in low angle group in men than in women.

Full Text Available Introduction: Death of breast cancer remains the highest position in the totem of incidents not only in Indonesia but also in the world. Its treatment process, which in fact brings huge impacts to the life quality of breast cancer patients in terms of physique, psychology, and social life, shapes a number of behavioral patterns throughout their life. The aim of this research is thus to explore patterns of breast cancer patients in sustaining their lifespan. Method: This research is designed using ethno-nursing qualitative approach. The sampling technique is done purposively to 6 informants, all of whom are breast cancer patients in Garut District, West Java, Indonesia. Data collecting is done through interviews and participatory observation. Data transcription is analyzed using ethno-nursing analysis method. Results: The result of the research shows four domains occurring as a pattern of inculturation of breast cancer patients in Sundanese culture, namely 1 dedication as wife and mother of Sundanese breast cancer patients, 2 medicine seeking for the rest of their life, 3 factors affecting to breast cancer patients adaptation for daily routines, and 4 family gathering as a meaning for end of life. Discussion: The result of this research shows an interconnected cultural pattern in the life of these patients. It is thus advised that nurses provide service to breast cancer clients by applying nursing care inherent to their cultural values.

Mitochondrial myopathy comprises various clinical subforms of neuromuscular disorders that are characterised by impaired mitochondrial energy metabolism due to dysfunction of the mitochondrial respiratory chain. No comprehensive and targeted cardiovascular magnetic resonance (CMR) studies have been performed so far in patients with mitochondrial disorders. The present study aimed at characterising cardiac disease manifestations in patients with mitochondrial myopathy and elucidating the in vivo cardiac damage pattern of patients with different subforms of mitochondrial disease by CMR studies. In a prospective study, 37 patients with mitochondrial myopathy underwent comprehensive neurological and cardiac evaluations including physical examination, resting ECG and CMR. The CMR studies comprised cine-CMR, T2-weighted "edema" imaging and T1-weighted late-gadolinium-enhancement (LGE) imaging. Various patterns and degrees of skeletal myopathy were present in the participants of this study, whereas clinical symptoms such as chest pain symptoms (in eight (22%) patients) and various degrees of dyspnea (in 16 (43%) patients) were less frequent. Pathological ECG findings were documented in eight (22%) patients. T2-weighted "edema" imaging was positive in one (3%) patient with MELAS (mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes) only. LGE imaging demonstrated the presence of non-ischemic LGE in 12 (32%) patients: 10 out of 24 (42%) patients with CPEO (chronic progressive external ophthalmoplegia) or KSS (Kearns-Sayre syndrome) and 2 of 3 (67%) patients with MELAS were LGE positive. All 10 LGE-positive patients with CPEO or KSS demonstrated a potentially typical pattern of diffuse intramural LGE in the left-ventricular (LV) inferolateral segments. Cardiac involvement is a frequent finding in patients with mitochondrial myopathy. A potentially characteristic pattern of diffuse intramural LGE in the LV inferolateral segments was identified in

Real-world evidence on treatment of hyperlipidaemia (HLD) in Japan is limited. We aimed to describe treatment patterns, persistence with, and adherence to treatment in Japanese patients with HLD. Retrospective analyses of adult HLD patients receiving drug therapy in 2014-2015 were conducted using the Japan Medical Data Center (JMDC) and Medical Data Vision (MDV) databases. Depending on their HLD treatment history, individuals were categorised as untreated (UT) or previously treated (PT), and were followed for at least 12 months. Outcomes of interest included prescribing patterns of HLD drug classes, persistence with treatment at 12 months, and adherence to treatment. Data for 49,582 and 53,865 patients from the JMDC and MDV databases, respectively, were analysed. First-line HLD prescriptions for UT patients were predominantly for moderate statins (JMDC: 75.9%, MDV: 77.0%). PT patients most commonly received combination therapy (JMDC: 43.9%, MDV: 52.6%). Approximately half of the UT patients discontinued treatment during observation. Within each cohort, persistence rates were lower in UT patients than in PT patients (JMDC: 45.0% vs. 77.5%; MDV: 51.9% vs. 85.3%). Adherence was ≥80% across almost all HLD drug classes, and was slightly lower in the JMDC cohort than MDV cohort. Most common prescriptions were moderate statins in UT patients and combination therapy in PT patients. The high discontinuation rate of HLD therapy in UT patients warrants further investigation and identification of methods to encourage and support long-term persistence. Copyright © 2018.

Uterine fibroid (myoma) is one of the most common diseases in women. Although there are several studies on the efficacy of Chinese herbs, there is a lack of large-scale survey on the use of traditional Chinese medicine (TCM) for the treatment of uterine fibroid. This study aimed to investigate the utilization of Chinese herbal products for patients with uterine fibroid, prescribed by licensed TCM doctors in Taiwan. A random sample comprised of one million individuals with newly diagnosed uterine fibroid between 2002 and 2010 from the Taiwanese National Health Insurance Research Database was analyzed. Demographic characteristics, TCM usage, the frequency as well as average daily dose of Chinese herbal formulas and the single herbs prescribed for patients with uterine fibroid, were analyzed. Overall, 35,786 newly diagnosed subjects with uterine fibroid were included. Majority of these patients (87.1%; n=31,161) had visited TCM clinics. Among them, 61.8% of their visits used Chinese herbal remedies. Patients less than 45 years of age tended to use TCM more frequently than elder patients. Gui-Zhi-Fu-Ling-Wan (Cinnamon Twig and Poria Pill) was the most frequently prescribed Chinese herbal formula, while San-Leng (Rhizoma Sparganii) was the most commonly prescribed single herb. Our study identified the characteristics and prescription patterns of TCM for patients with uterine fibroid in Taiwan. Further basic mechanistic studies and clinical trials are needed to confirm the therapeutic effects and mechanisms. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The effectiveness of mathematical tools for pattern recognition as applied to numerical assessments of the immune status of patients exposed to ecological hazards is evaluated by experimentation. The immune status is estimated according to a two-class scheme (norm/abnormality) based on blood indicators of immunity for the patients examined. The task of categorizing patients by immunological parameters of blood is shown to be resolved with high effectiveness for determining the immune status [ru

To describe the pulmonary complications following hematopoietic stem cell transplantation (HSCT) that can present with a 'crazy-paving' pattern in high-resolution CT scans. Retrospective review of medical records from 2,537 patients who underwent HSCT. The 'crazy-paving' pattern consists of interlobular and intralobular septal thickening superimposed on an area of ground-glass attenuation on high-resolution CT scans. The CT scans were retrospectively reviewed by two radiologists, who reached final decisions by consensus. We identified 10 cases (2.02%), seven male and three female, with pulmonary complications following HSCT that presented with the 'crazy-paving' pattern. Seven (70%) patients had infectious pneumonia (adenovirus, herpes simplex, influenza virus, cytomegalovirus, respiratory syncytial virus, and toxoplasmosis), and three patients presented with non-infectious complications (idiopathic pneumonia syndrome and acute pulmonary edema). The 'crazy-paving' pattern was bilateral in all cases, with diffuse distribution in nine patients (90%), predominantly in the middle and inferior lung regions in seven patients (70%), and involving the anterior and posterior regions of the lungs in nine patients (90%). The 'crazy-paving' pattern is rare in HSCT recipients with pulmonary complications and is associated with infectious complications more commonly than non-infectious conditions

Full Text Available Background: The prevalence and clinical patterns of psoriatic arthritis (PsA varies in different parts of the world and there is little clinical and epidemiological data from the Indian subcontinent. Aims: Our study was designed to evaluate the prevalence and clinical patterns of PsA in Indian patients. Methods: This was a non-interventional, cross-sectional study, in which 1149 consecutive psoriasis patients seen over 1 year were screened for PsA according to classification of psoriatic arthritis (CASPAR criteria. Demographic and disease parameters were recorded including Psoriasis Area and Severity Index (PASI, Nail Psoriasis Severity Index (NAPSI, and number of swollen and tender joints. Results: Among 1149 patients with psoriasis, 100 (8.7% patients had PsA, of which 83% were newly diagnosed. The most common pattern was symmetrical polyarthritis (58%, followed by spondyloarthropathy 49%, asymmetric oligoarthritis (21%, isolated spondyloarthropathy (5%, predominant distal interphalangeal arthritis (3%, and arthritis mutilans (1%. Enthesitis and dactylitis were present in 67% and 26% of cases, respectively. The mean number of swollen and tender joints were 3.63 ± 3.59 (range, 0-22 and 7.76 ± 6.03 (range, 1-26, respectively. Nail changes were present in 87% of the cases. The median PASI and NAPSI of the subjects with PsA was 3.6 and 20, respectively. There was no significant correlation of number of swollen/tender joints with PASI or NAPSI. Conclusion: There is a relatively low prevalence of PsA among Indian psoriasis patients presenting to dermatologists. No correlation was found between the severity of skin and nail involvement and articular disease.

Background As the number of people with Internet access rises, so does the use of the Internet as a potentially valuable source for health information. Insight into patient use of this information and its correlates over time may reveal changes in the digital divide based on patient age and education. Existing research has focused on patient characteristics that predict Internet information use and research on treatment context is rare. Objective This study aims to (1) present data on the proportion of newly diagnosed breast cancer patients treated in German breast centers from 2007 to 2013 who used the Internet for information on their disease, (2) look into correlations between Internet utilization and sociodemographic characteristics and if these change over time, and (3) determine if use of Internet information varies with the hospitals in which the patients were initially treated. Methods Data about utilization of the Internet for breast cancer–specific health information was obtained in a postal survey of breast cancer patients that is conducted annually in Germany with a steady response rate of 87% of consenting patients. Data from the survey were combined with data obtained by hospital personnel (eg, cancer stage and type of surgery). Data from 27,491 patients from 7 consecutive annual surveys were analyzed for this paper using multilevel regression modeling to account for clustering of patients in specific hospitals. Results Breast cancer patients seeking disease-specific information on the Internet increased significantly from 26.96% (853/3164) in 2007 to 37.21% (1485/3991) in 2013. Similar patterns of demographic correlates were found for all 7 cohorts. Older patients (≥70 years) and patients with <10 years of formal education were less likely to use the Internet for information on topics related to their disease. Internet use was significantly higher among privately insured patients and patients living with a partner. Higher cancer stage and a

To determine between-hospital variation in interventions provided to patients with do not resuscitate (DNR) orders. United States Agency of Healthcare Research and Quality, Healthcare Cost and Utilization Project, California State Inpatient Database. Retrospective cohort study including hospitalized patients aged 40 and older with potential indications for invasive treatments: in-hospital cardiac arrest (indication for CPR), acute respiratory failure (mechanical ventilation), acute renal failure (hemodialysis), septic shock (central venous catheterization), and palliative care. Hierarchical logistic regression to determine associations of hospital "early" DNR rates (DNR order placed within 24 hours of admission) with utilization of invasive interventions. California State Inpatient Database, year 2011. Patients with DNR orders at high-DNR-rate hospitals were less likely to receive invasive mechanical ventilation for acute respiratory failure or hemodialysis for acute renal failure, but more likely to receive palliative care than DNR patients at low-DNR-rate hospitals. Patients without DNR orders experienced similar rates of invasive interventions regardless of hospital DNR rates. Hospitals vary widely in the scope of invasive or organ-supporting treatments provided to patients with DNR orders. © Health Research and Educational Trust.

We assessed the clinical utility of [11C]flumazenil-PET (FMZ-PET) prospectively in 100 epileptic patients undergoing a pre-surgical evaluation, and defined the specific contribution of this neuro-imaging technique with respect to those of MRI and [18F]fluorodeoxyglucose-PET (FDG-PET). All patients benefited from a long term video-EEG monitoring, whereas an intracranial EEG investigation was performed in 40 cases. Most of our patients (73%) demonstrated a FMZ-PET abnormality; this hit rate was significantly higher in temporal lobe epilepsy (94%) than in other types of epilepsy (50%) (P lobe epilepsy associated with MRI signs of hippocampal sclerosis, FMZ-PET abnormalities delineated the site of seizure onset precisely, whenever they were coextensive with FDG-PET abnormalities; (ii) in bi-temporal epilepsy, FMZ-PET helped to confirm the bilateral origin of seizures by showing a specific pattern of decreased FMZ binding in both temporal lobes in 33% of cases; (iii) in patients with a unilateral cryptogenic frontal lobe epilepsy, FMZ-PET provided further evidence of the side and site of seizure onset in 55% of cases. Thus, FMZ-PET deserves to be included in the pre-surgical evaluation of these specific categories of epileptic patients, representing approximately half of the population considered for epilepsy surgery.

Oral hygiene instruction is an intervention widely practiced but increased knowledge about oral health does not necessarily dramatically impact oral disease prevalence in populations. We aimed to measure plaque and bleeding in periodontal patients over time to determine patterns of patient response to oral hygiene instructions. Longitudinal plaque and bleeding index data were evaluated in 227 periodontal patients to determine the impact of oral hygiene instructions. Over multiple visits, we determined relative plaque accumulation and gingival bleeding for each patient. Subsequently, we grouped them in three types of oral hygiene status in response to initial instructions, using the longitudinal data over the period they were treated and followed for their periodontal needs. These patterns of oral hygiene based on the plaque and gingival bleeding indexes were evaluated based on age, sex, ethnic background, interleukin 1 alpha and beta genotypes, diabetes status, smoking habits, and other concomitant diseases. Chi-square and Fisher's exact tests were used to determine if any differences between these variables were statistically significant with alpha set at 0.05. Three patterns in response to oral hygiene instructions emerged. Plaque and gingival bleeding indexes improved, worsened, or fluctuated over time in the periodontal patients studied. Out of all the confounders considered, only ethnic background showed statistically significant differences. White individuals more often than other ethnic groups fluctuated in regards to oral hygiene quality after instructions. There are different responses to professional oral hygiene instructions. These responses may be related to ethnicity.

Among individuals diagnosed with schizophrenia, approximately 20%-33% are recognized as treatment-resistant schizophrenia (TRS) patients. These TRS patients suffer more severely from the disease but struggle to benefit from existing antipsychotic treatments. A few recent studies suggested that schizophrenia may be caused by impaired synaptic plasticity that manifests as functional dysconnectivity in the brain, however, few of those studies focused on the functional connectivity changes in the brains of TRS groups. In this study, we compared the whole brain connectivity variations in TRS patients, their unaffected siblings, and healthy controls. Connectivity network features between and within the 116 automated anatomical labeling (AAL) brain regions were calculated and compared using maps created with three contrasts: patient vs. control, patient vs. sibling, and sibling vs. To evaluate the predictive power of the selected features, we performed a multivariate classification approach. We also evaluated the influence of six important clinical measures (e.g. age, education level) on the connectivity features. This study identified abnormal significant connectivity changes of three patterns in TRS patients and their unaffected siblings: 1) 69 patient-specific connectivity (PCN); 2) 102 shared connectivity (SCN); and 3) 457 unshared connectivity (UCN). While the first two patterns were widely reported by previous non-TRS specific studies, we were among the first to report widespread significant connectivity differences between TRS patient groups and their healthy sibling groups. Observations of this study may provide new insights for the understanding of the neurophysiological mechanisms of TRS.

Despite numerous studies, the role of patent foramen ovale (PFO) as a risk factor for stroke due to paradoxical embolism is still controversial. On the assumption that specific lesion patterns, in particular multiple acute ischaemic lesions on diffusion-weighted magnetic resonance imaging, indicate a cardioembolic origin, we compared the MRI findings in stroke patients with right-to-left shunt (RLS) and those without. The records of 486 patients with diagnosis of cerebral ischaemia were reviewed. For detection of RLS, contrast-enhanced transcranial Doppler (c-TCD) was carried out in all patients. An MRI scan of the brain was performed in all patients. Affected vascular territories were divided into anterior cerebral artery, middle cerebral artery, vertebrobasilar artery system including posterior cerebral artery, brain stem and cerebellar stroke, and strokes occurring in more than one territory. We did not find a specific difference in neuroradiological lesion patterns in patients with RLS compared with patients without RLS. In particular, 23 of 165 patients (13.9%) with RLS showed multiple ischaemic lesions on MRI in comparison with 45 of 321 patients (14.0%) without RLS (P = 0.98). These findings also applied for the subgroup of cryptogenic strokes with and without RLS. We found no association between an ischaemic lesion pattern that is considered as being typical for stroke due to cardiac embolism and the existence of PFO. Therefore, our findings do not provide any support for the common theory of paradoxical embolism as a major cause of stroke in PFO carriers.

Full Text Available Background: The treatment of diseases by use of essential medicines, prescribed by generic names, has been emphasized by WHO and National Health Policy of India. Drugs used in gynaecology are one of the top selling drugs in India; however they are least studied with respect to drug utilization. Thus present study was undertaken to analyze drug utilization pattern of gynecology OPD in a tertiary care hospital. Materials and Methods: A retrospective, cross sectional, observational study of prescriptions in Gynecology OPD. Data was obtained from an electronic medical record database of patients that attended Gynecology OPD during the study period. Prescription records of patients were screened as per inclusion and exclusion criteria and 300 prescriptions were randomly selected by Openepi software. Patient related and drug related information was collected on a customized data collection sheet. Results: The mean age of patients was 30.19+9.83 years and common age of presentation was >18-30 years. In infective cases, vaginal discharge (10.33% was common, and in non-infective cases, menstrual disorders (24% were common. The average number of drugs per prescription was 3.47+1.53. In drug category, minerals (30.94% were most commonly prescribed, followed by antimicrobials (24.98%, and NSAIDs (13.37%. Polypharmacy was observed in 96.33% of the prescriptions. Conclusion: It is only by drug utilization studies that burden of diseases and corresponding utilization of drugs in gynecology can be measured. In our study majority of the drugs prescribed were generic which were from the essential medical list NLEM and WHO.

2011-01-01

Executive Summary Objective The objective of this evidence-based analysis was to evaluate the clinical utility of serologic testing for celiac disease in asymptomatic individuals presenting with one of the non-gastrointestinal conditions evaluated in this report. The clinical utility was based on the effects of a gluten-free diet (GFD) on outcomes specific to each of these conditions. The prevalence of celiac disease in asymptomatic individuals and one of these non-gastrointestinal conditions was also evaluated. Clinical Need and Target Population Celiac Disease Celiac disease is an autoimmune disease characterized by a chronic inflammatory state of the proximal small bowel mucosa accompanied by structural and functional changes. Technology Under Evaluation Serologic Tests for Celiac Disease There are a number of serologic tests for celiac disease available. Serologic tests are automated with the exception of the anti-endomysial antibody test, which is more time-consuming and operator-dependent than the other tests. Research Questions What is the prevalence of asymptomatic celiac disease in patients presenting with one of the non-gastrointestinal conditions evaluated? What is the effect of the gluten-free diet on condition-specific outcomes in patients with asymptomatic celiac disease presenting with one of the non-gastrointestinal conditions evaluated? What is the clinical utility of serologic testing for celiac disease in asymptomatic patients presenting with one of the non-gastrointestinal conditions evaluated? The clinical utility was defined as the impact of the GFD on disease specific outcomes. What is the risk of all-cause mortality and lymphoma in individuals with asymptomatic celiac disease? What is the budget impact of serologic testing for celiac disease in asymptomatic subjects presenting with one of the non-gastrointestinal conditions evaluated? Research Methods Study Population The study population consisted of individuals with newly diagnosed celiac

Until now little is known about the role of participation in self-help groups alone or combined with psychotherapy in post-in-patient care. In the present study 2933 patients were questioned about their experience of self-help groups and psychotherapy after discharge from a clinic for psychosomatic medicine and psychotherapy. Nearly 8 % of them utilized self-help groups (mostly combined with out-patient psychotherapy), and altogether 68 % out-patient psychotherapy following in-patient treatment. Patients without out-patient treatment were psychologically less burdened and had better resources than participants of self-help groups or psychotherapy. Self-help group members differed from patients in out-patient psychotherapy by expressing a more positive opinion of groupwork and higher openness to new experiences. Additionly, they had discussed the topic of self-help groups more frequently with their therapists. This may be a starting-point for promoting more self-help activities of patients in the future.

Comorbid psychiatric complications are a common occurrence in Parkinson's disease (PD). However, the majority of people with PD experiencing mental health problems do not receive any professional treatment. A total of 327 Australian adults with PD completed a cross-sectional survey examining patterns of mental health service utilization and predictors of willingness to seek future mental health treatment. Only 8% of participants were currently engaged in mental health treatment despite elevated levels of depressive and anxiety symptoms. The lifetime service use rate was also low at 24%. Logistic regression analysis showed that, second to prior treatment experience (odds ratio [OR] = 3.28, 95% confidence interval [CI] = 1.46-7.35), having had a discussion about psychological symptoms with a primary PD neurologist was the next most important predictor and tripled the likelihood of an individual being willing to seek future treatment, (OR = 3.01, 95% CI = 1.72-5.27). This study highlights the integral role of the PD neurologist in facilitating awareness and treatment of mental health problems for individuals with PD. © The Author(s) 2014.

Thousands of physicians attend scientific meetings annually. Although hospital physician staffing and composition may be affected by meetings, patient outcomes and treatment patterns during meeting dates are unknown. To analyze mortality and treatment differences among patients admitted with acute cardiovascular conditions during dates of national cardiology meetings compared with nonmeeting dates. Retrospective analysis of 30-day mortality among Medicare beneficiaries hospitalized with acute myocardial infarction (AMI), heart failure, or cardiac arrest from 2002 through 2011 during dates of 2 national cardiology meetings compared with identical nonmeeting days in the 3 weeks before and after conferences (AMI, 8570 hospitalizations during 82 meeting days and 57,471 during 492 nonmeeting days; heart failure, 19,282 during meeting days and 11,4591 during nonmeeting days; cardiac arrest, 1564 during meeting days and 9580 during nonmeeting days). Multivariable analyses were conducted separately for major teaching hospitals and nonteaching hospitals and for low- and high-risk patients. Differences in treatment utilization were assessed. Hospitalization during cardiology meeting dates. Thirty-day mortality, procedure rates, charges, length of stay. Patient characteristics were similar between meeting and nonmeeting dates. In teaching hospitals, adjusted 30-day mortality was lower among high-risk patients with heart failure or cardiac arrest admitted during meeting vs nonmeeting dates (heart failure, 17.5% [95% CI, 13.7%-21.2%] vs 24.8% [95% CI, 22.9%-26.6%]; P cardiology meetings. High-risk patients with heart failure and cardiac arrest hospitalized in teaching hospitals had lower 30-day mortality when admitted during dates of national cardiology meetings. High-risk patients with AMI admitted to teaching hospitals during meetings were less likely to receive PCI, without any mortality effect.

The aim of this study was to investigate trends in utilization and spending for medical imaging, using medical visits resulting in imaging as a novel metric of utilization. Utilization and spending for medical imaging were examined using (1) Medicare Part B claims data from 2003 to 2011 to measure per-enrollee spending and (2) household component events data on the elderly Medicare-age population from the Medical Expenditure Panel Survey from 2003 to 2010 to measure utilization as a function of clinical encounters. Annual health spending and Medicare payments for imaging for the elderly population grew from $294 per enrollee in 2003 to $418 in 2006 and had declined to $390 by 2011. Over this entire time, however, annual medical visits by a similar Medicare-age (≥ 65 years old) population resulting in imaging trended consistently downward, from 12.8% in 2003 to 10.6% in 2011. Despite early growth and then more recent declines in average Medicare spending per enrollee since 2003, the percentage of patient encounters resulting in medical imaging has significantly and consistently declined nationwide. Spending alone is thus an incomplete measure of changes in the role and utilization of medical imaging in overall patient care. As policymakers focus on medical imaging, a thoughtful analysis of payment policy influencing imaging utilization, and its role in concurrent and downstream patient care, will be critical to ensure appropriate patient access.

Full Text Available Non-invasive EEG-based Brain-Computer Interfaces (BCI can be promising for the motor neuro-rehabilitation of paraplegic patients. However, this shall require detailed knowledge of the abnormalities in the EEG signatures of paraplegic patients. The association of abnormalities in different subgroups of patients and their relation to the sensorimotor integration are relevant for the design, implementation and use of BCI systems in patient populations. This study explores the patterns of abnormalities of movement related cortical potentials (MRCP during motor imagery tasks of feet and right hand in patients with paraplegia (including the subgroups with/without central neuropathic pain and complete/incomplete injury patients and the level of distinctiveness of abnormalities in these groups using pattern classification. The most notable observed abnormalities were the amplified execution negativity and its slower rebound in the patient group. The potential underlying mechanisms behind these changes and other minor dissimilarities in patients’ subgroups, as well as the relevance to BCI applications, are discussed. The findings are of interest from a neurological perspective as well as for BCI-assisted neuro-rehabilitation and therapy.

Whole genome sequencing reveals complex evolution patterns of multidrug-resistant Mycobacterium tuberculosis Beijing strains in patients.

Directory of Open Access Journals (Sweden)

Matthias Merker

Full Text Available Multidrug-resistant (MDR Mycobacterium tuberculosis complex (MTBC strains represent a major threat for tuberculosis (TB control. Treatment of MDR-TB patients is long and less effective, resulting in a significant number of treatment failures. The development of further resistances leads to extensively drug-resistant (XDR variants. However, data on the individual reasons for treatment failure, e.g. an induced mutational burst, and on the evolution of bacteria in the patient are only sparsely available. To address this question, we investigated the intra-patient evolution of serial MTBC isolates obtained from three MDR-TB patients undergoing longitudinal treatment, finally leading to XDR-TB. Sequential isolates displayed identical IS6110 fingerprint patterns, suggesting the absence of exogenous re-infection. We utilized whole genome sequencing (WGS to screen for variations in three isolates from Patient A and four isolates from Patient B and C, respectively. Acquired polymorphisms were subsequently validated in up to 15 serial isolates by Sanger sequencing. We determined eight (Patient A and nine (Patient B polymorphisms, which occurred in a stepwise manner during the course of the therapy and were linked to resistance or a potential compensatory mechanism. For both patients, our analysis revealed the long-term co-existence of clonal subpopulations that displayed different drug resistance allele combinations. Out of these, the most resistant clone was fixed in the population. In contrast, baseline and follow-up isolates of Patient C were distinguished each by eleven unique polymorphisms, indicating an exogenous re-infection with an XDR strain not detected by IS6110 RFLP typing. Our study demonstrates that intra-patient microevolution of MDR-MTBC strains under longitudinal treatment is more complex than previously anticipated. However, a mutator phenotype was not detected. The presence of different subpopulations might confound phenotypic and

Full Text Available Lars Oddershede,1,2 Jan Jesper Andreasen,1 Lars Ehlers2 1Department of Cardiothoracic Surgery, Center for Cardiovascular Research, Aalborg University Hospital, Aalborg, Denmark; 2Danish Center for Healthcare Improvements, Faculty of Social Sciences and Faculty of Health Sciences, Aalborg University, Aalborg East, Denmark Introduction: In health economic evaluations, mapping can be used to estimate utility values from other health outcomes in order to calculate quality adjusted life-years. Currently, no methods exist to map visual analog scale (VAS scores to utility values. This study aimed to develop and propose a statistical algorithm for mapping five dimensions of health, measured on VASs, to utility scores in patients suffering from cardiovascular disease. Methods: Patients undergoing coronary artery bypass grafting at Aalborg University Hospital in Denmark were asked to score their health using the five VAS items (mobility, self-care, ability to perform usual activities, pain, and presence of anxiety or depression and the EuroQol 5 Dimensions questionnaire. Regression analysis was used to estimate four mapping models from patients' age, sex, and the self-reported VAS scores. Prediction errors were compared between mapping models and on subsets of the observed utility scores. Agreement between predicted and observed values was assessed using Bland–Altman plots. Results: Random effects generalized least squares (GLS regression yielded the best results when quadratic terms of VAS scores were included. Mapping models fitted using the Tobit model and censored least absolute deviation regression did not appear superior to GLS regression. The mapping models were able to explain approximately 63%–65% of the variation in the observed utility scores. The mean absolute error of predictions increased as the observed utility values decreased. Conclusion: We concluded that it was possible to predict utility scores from VAS scores of the five

Purpose: To directly compare (1) radiation treatment utilization patterns; (2) risks of subsequent mastectomy; and (3) costs of radiation treatment in patients treated with brachytherapy versus whole-breast irradiation (WBI), in a national, contemporary cohort of women with incident breast cancer, aged 64 years and younger. Methods and Materials: Using MarketScan health care claims data, we identified 45,884 invasive breast cancer patients (aged 18-64 years), treated from 2003 to 2010 with lumpectomy, followed by brachytherapy (n=3134) or whole-breast irradiation (n=42,750). We stratified patients into risk groups according to age (Age<50 vs Age≥50) and endocrine therapy status (Endocrine− vs Endocrine+). “Endocrine+” patients filled an endocrine therapy prescription within 1 year after lumpectomy. Pathologic hormone receptor status was not available in this dataset. In brachytherapy versus WBI patients, utilization trends and 5-year subsequent mastectomy risks were compared. Stratified, adjusted subsequent mastectomy risks were calculated using proportional hazards regression. Results: Brachytherapy utilization increased from 2003 to 2010: in patients Age<50, from 0.6% to 4.9%; patients Age≥50 from 2.2% to 11.3%; Endocrine− patients, 1.3% to 9.4%; Endocrine+ patients, 1.9% to 9.7%. Age influenced treatment selection more than endocrine status: 17% of brachytherapy patients were Age<50 versus 32% of WBI patients (P<.001); whereas 41% of brachytherapy patients were Endocrine–versus 44% of WBI patients (P=.003). Highest absolute 5-year subsequent mastectomy risks occurred in Endocrine−/Age<50 patients (24.4% after brachytherapy vs 9.0% after WBI (hazard ratio [HR] 2.18, 95% confidence interval [CI] 1.37-3.47); intermediate risks in Endocrine−/Age≥50 patients (8.6% vs 4.9%; HR 1.76, 95% CI 1.26-2.46); and lowest risks in Endocrine+ patients of any age: Endocrine+/Age<50 (5.5% vs 4.5%; HR 1.18, 95% CI 0.61-2.31); Endocrine+/Age≥50 (4.2% vs 2

The aim of this study was to examine whether lag sequential analysis could be used to describe eye gaze orientation between clinicians and patients in the medical encounter. This topic is particularly important as new technologies are implemented into multiuser health care settings in which trust is critical and nonverbal cues are integral to achieving trust. This analysis method could lead to design guidelines for technologies and more effective assessments of interventions. Nonverbal communication patterns are important aspects of clinician-patient interactions and may affect patient outcomes. The eye gaze behaviors of clinicians and patients in 110 videotaped medical encounters were analyzed using the lag sequential method to identify significant behavior sequences. Lag sequential analysis included both event-based lag and time-based lag. Results from event-based lag analysis showed that the patient's gaze followed that of the clinician, whereas the clinician's gaze did not follow the patient's. Time-based sequential analysis showed that responses from the patient usually occurred within 2 s after the initial behavior of the clinician. Our data suggest that the clinician's gaze significantly affects the medical encounter but that the converse is not true. Findings from this research have implications for the design of clinical work systems and modeling interactions. Similar research methods could be used to identify different behavior patterns in clinical settings (physical layout, technology, etc.) to facilitate and evaluate clinical work system designs.

This study aimed to evaluate the pattern of infarct in basal ganglia region in tuberculous meningitis (TBM) and ischemic strokes and its sensitivity and specificity in the diagnosis of these disorders. Patients with TBM and ischemic strokes in basal ganglia region were retrospectively evaluated from our tuberculous meningitis and ischemic stroke registry. Magnetic resonance imaging findings were grouped into anterior (caudate, genu, anterior limb of internal capsule, anteromedial thalamus) and posterior (lentiform nuclei, posterior limb of internal capsule, posterolateral thalamus). The sensitivity and specificity of these patterns in diagnosing TBM and ischemic stroke were evaluated. There were 24 patients in each group. Infarct in TBM was purely anterior in eight patients and in ischemic stroke purely posterior in 18 patients. The frequency of caudate infarct was significantly higher in TBM compared to ischemic stroke (37.5% vs 8.3%). In TBM patients, purely posterior infarcts were present in seven patients; three had associated risk factors of ischemic stroke. The sensitivity of pure anterior infarct in the diagnosis of TBM was 33%, specificity 91.66%. For ischemic stroke, the sensitivity of posterior infarct was 75% and specificity 70.83%. TBM patients having infarcts in posterior region should be looked for associated risk factors of ischemic stroke. (orig.)

Poor medication adherence contributes to negative treatment response, symptom relapse, and hospitalizations in schizophrenia. Many health plans use claims-based measures like medication possession ratios or proportion of days covered (PDC) to measure patient adherence to antipsychotics. Classifying patients solely on the basis of a single average PDC measure, however, may mask clinically meaningful variations over time in how patients arrive at an average PDC level. To model patterns of medication adherence evolving over time for patients with schizophrenia who initiated treatment with an oral atypical antipsychotic and, based on these patterns, to identify groups of patients with different adherence behaviors. We analyzed health insurance claims for patients aged ≥ 18 years with schizophrenia and newly prescribed oral atypical antipsychotics in 2007-2013 from 3 U.S. insurance claims databases: Truven MarketScan (Medicaid and commercial) and Humana (Medicare). Group-based trajectory modeling (GBTM) was used to stratify patients into groups with distinct trends in adherence and to estimate trends for each group. The response variable was the probability of adherence (defined as PDC ≥ 80%) in each 30-day period after the patient initiated antipsychotic therapy. GBTM proceeds from the premise that there are multiple distinct adherence groups. Patient demographics, health status characteristics, and health care resource use metrics were used to identify differences in patient populations across adherence trajectory groups. Among the 29,607 patients who met the inclusion criteria, 6 distinct adherence trajectory groups emerged from the data: adherent (33%); gradual discontinuation after 3 months (15%), 6 months (7%), and 9 months (5%); stop-start after 6 months (15%); and immediate discontinuation (25%). Compared to patients 18-24 years of age in the adherent group, patients displaying a stop-start pattern after 6 months had greater odds of having a history of drug

The usual dietary intake of individuals over 1 year was collected using a validated semi-quantitative food frequency questionnaire. Weight, height, and waist circumference were measured according to standard protocol. The two major dietary patterns identified by factor analysis were healthy and unhealthy dietary patterns. After adjustment for potential confounders, subjects in the highest quintile of the healthy dietary pattern scores had a lower odds ratio for the general obesity when compared to the lowest quintile (OR = 0.45, 95 % CI = 0.26 - 0.79, P for trend = 0.02), while patients in the highest quintile of the unhealthy dietary pattern scores had greater odds for the general obesity (OR = 3.2, 95 % CI = 1.8 - 5.9, P for trend diabetes mellitus, a healthy dietary pattern is inversely associated and an unhealthy dietary pattern is directly associated with general obesity.

Little is known about the relationship between implant patient mortality compared to reference populations. The aim of this study was to report the mortality pattern in patients treated with dental implants up to a 15-year period, and to compare this to mortality in reference populations with regard to age at surgery, sex, and degree of tooth loss. Patient cumulative survival rate (CSR) was calculated for a total of 4,231 treated implant patients from a single clinic. Information was based on surgical registers in the clinic and the National Population Register in Sweden. Patients were arranged into age groups of 10 years, and CSR was compared to that of the reference population of comparable age and reported in relation to age at surgery, sex, and type of jaw/dentition. A similar, consistent, general relationship between CSR of different age groups of implant patients and reference populations could be observed for all parameters studied. Completely edentulous patients presented higher mortality than partially edentulous patients (P age groups showed mortality similar to or higher than reference populations, while older patient age groups showed increasingly lower mortality than comparable reference populations for edentulous and partially edentulous patients (P age groups of patients compared to reference populations was observed, indicating higher patient mortality in younger age groups and lower in older groups. The reported pattern is not assumed to be related to implant treatment per se, but is assumed to reflect the variation in general health of a selected subgroup of treated implant patients compared to the reference population in different age groups.

This article defines and describes best practices for the academic and business community to generate evidence of clinical utility for cancer molecular diagnostic assays. Beyond analytical and clinical validation, successful demonstration of clinical utility involves developing sufficient evidence to demonstrate that a diagnostic test results in an improvement in patient outcomes. This discussion is complementary to theoretical frameworks described in previously published guidance and literature reports by the U.S. Food and Drug Administration, Centers for Disease Control and Prevention, Institute of Medicine, and Center for Medical Technology Policy, among others. These reports are comprehensive and specifically clarify appropriate clinical use, adoption, and payer reimbursement for assay manufacturers, as well as Clinical Laboratory Improvement Amendments-certified laboratories, including those that develop assays (laboratory developed tests). Practical criteria and steps for establishing clinical utility are crucial to subsequent decisions for reimbursement without which high-performing molecular diagnostics will have limited availability to patients with cancer and fail to translate scientific advances into high-quality and cost-effective cancer care.

Full Text Available Among individuals diagnosed with schizophrenia, approximately 20%–33% are recognized as treatment-resistant schizophrenia (TRS patients. These TRS patients suffer more severely from the disease but struggle to benefit from existing antipsychotic treatments. A few recent studies suggested that schizophrenia may be caused by impaired synaptic plasticity that manifests as functional dysconnectivity in the brain, however, few of those studies focused on the functional connectivity changes in the brains of TRS groups. In this study, we compared the whole brain connectivity variations in TRS patients, their unaffected siblings, and healthy controls. Connectivity network features between and within the 116 automated anatomical labeling (AAL brain regions were calculated and compared using maps created with three contrasts: patient vs. control, patient vs. sibling, and sibling vs. control. To evaluate the predictive power of the selected features, we performed a multivariate classification approach. We also evaluated the influence of six important clinical measures (e.g. age, education level on the connectivity features. This study identified abnormal significant connectivity changes of three patterns in TRS patients and their unaffected siblings: 1 69 patient-specific connectivity (PCN; 2 102 shared connectivity (SCN; and 3 457 unshared connectivity (UCN. While the first two patterns were widely reported by previous non-TRS specific studies, we were among the first to report widespread significant connectivity differences between TRS patient groups and their healthy sibling groups. Observations of this study may provide new insights for the understanding of the neurophysiological mechanisms of TRS.

During the period from June. 1969 to Dec. 1970, the serum protein electrophoretic patterns of 44 cases of various cancer patients have been studied to determine the alterations in serum protein fractions in patients who were responding to irradiation or those failing. The serum electrophoretic pattern could be observed as an indicator of prognosis or radiosensitivity. A blood sample was obtained prior to any treatment and the follow up sampling was performed 2 times during radiation therapy. Serum total protein was determined by the method of Wolfson and serum electrophoresis was carried out by using Spinoco Model R B electrophoresis system. The results were following: Seven cases out of cases of cervical cancer responding favorably to radiotherapy showed decreased in Alpha-2 globulin fraction were increased. A case whose third time serum electrophoretic pattern showed multiple myeloma type died 5 months after radiotherapy with bone metastasis. Four cases out of 9 cases of favorably responded breast cancer patients showed decreased in Alpha-2 globulin foraction compared with 2 cases of unfavorable response showed increased in Alpha-2 globulin fraction

Initiatives to promote utility cycling in countries like Australia and the US, which have low rates of utility cycling, may be more effective if they first target recreational cyclists. This study aimed to describe patterns of utility cycling and examine its correlates, among cyclists in Queensland, Australia. An online survey was administered to adult members of a state-based cycling community and advocacy group (n=1813). The survey asked about demographic characteristics and cycling behavior, motivators and constraints. Utility cycling patterns were described, and logistic regression modeling was used to examine associations between utility cycling and other variables. Forty-seven percent of respondents reported utility cycling: most did so to commute (86%). Most journeys (83%) were >5 km. Being male, younger, employed full-time, or university-educated increased the likelihood of utility cycling (P<.05). Perceiving cycling to be a cheap or a convenient form of transport was associated with utility cycling (P<.05). The moderate rate of utility cycling among recreational cyclists highlights a potential to promote utility cycling among this group. To increase utility cycling, strategies should target female and older recreational cyclists and focus on making cycling a cheap and convenient mode of transport.

Chronic low back pain (CLBP) may be treated without opioids through the use of transcutaneous electrical nerve stimulation (TENS). However, no study has evaluated its clinical effect and economic impact as measured by opioid utilization and costs. The purpose of this study was to evaluate patients who were given TENS for CLBP compared to a matched group without TENS at one-year follow-up, to determine differences between opioid consumption. Opioid utilization and costs in patients who did and did not receive TENS were extracted from a Medicare supplemental administrative claims database. Patients were selected if they had at least two ICD-9-CM coded claims for low back pain in a three-month period and were then propensity score matched at a 1:1 ratio between patients who received TENS and those who did not. There were 22,913 patients in each group who had a minimum follow-up of one year. There were no significant demographic or comorbidity differences with the exception that TENS patients had more episodes of back pain. Significantly fewer patients in the TENS group required opioids at final follow-up (57.7 vs. 60.3%). TENS patients also had significantly fewer annual per-patient opioid costs compared to non-TENS patients ($169 vs. $192). There were significantly lower event rates in TENS patients compared to non-TENS patients when measured by opioid utilization (characterized by frequency of prescription refills) (3.82 vs. 4.08, respectively) or pharmacy utilization (31.67 vs. 32.25). The TENS group also demonstrated a significantly lower cost of these utilization events ($44 vs. $49) and avoided more opioid events (20.4 events fewer per 100 patients annually). Treatment of CLBP with TENS demonstrated significantly fewer patients requiring opioids, fewer events where a patient required an opioid prescription, and lower per-patient costs. Since TENS is both non-invasive and a non-narcotic, it may potentially allow physicians to be more aggressive in treating CLBP

High GH and IGF I levels increase tubular phosphate reabsorption in patients with acromegaly. We aimed to investigate the utility of serum phosphorus levels as an indicator for predicting chance of remission in acromegaly patients. Fifty-one patients (n: 51; F: 24, M: 27) with diagnosis of acromegaly were included in the study. Plasma IGF-1, Phosphorus (P) and nadir GH levels on oral glucose tolerance test (OGTT) at the time of diagnosis were analysed retrospectively. Patients were classified into two groups according to their plasma P levels; P ≤ 4.5 mg/dl (Group-1, n: 23, 45.1%), P > 4.5 mg/dl (Group-2, n: 28, 54.9%). Two groups were compared according to remission status; remission (n: 27) and non-remission (n: 24). Remission was defined with absence of clinical symptoms, normal plasma IGF-1 (adjusted for age and gender) and GH levels (acromegaly patients. Further studies with wider spectrum are needed to make specific suggestions.

The cytokines of acute leukemia (AL) patients have certain expression patterns, forming a complex network involved in diagnosis, progression, and prognosis. We collected the serum of different AL patients before and after complete remission (CR) for detection of cytokines by using an antibody chip. The expression patterns of cytokines were determined by using bioinformatics computational analysis. The results showed that there were significant differences in the cytokine expression patterns between AL patients and normal controls, as well as between acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). In confirmatory test, ELISA revealed the expression of uPAR in AL. Moreover, the bioinformatic analysis showed that the differentially expressed cytokines among the AL groups were involved in different biological behaviors and were closely related with the development of the disease. It was concluded that the cytokine expression pattern of AL patients is significantly different from that of healthy volunteers. Also, differences of cytokine expression patterns exist between AML and ALL, and between before and after CR in the same subtype of AL, which holds important clinical significance for revealing disease progression.

This work aimed to evaluate the use of a four-point glucagon stimulation test of C-peptide effect on glucose utilization in type 1 diabetic patients using a new mathematical model. A group of 32 type 1 diabetic patients and a group of 10 healthy control subjects underwent a four-point glucagon stimulation test with blood sampling at 0, 6, 15 and 30 min after 1 mg glucagon bolus intravenous administration. Pharmacokinetic and pharmacokinetic/pharmacodynamic models of C-peptide effect on glucose utilization versus area under curve (AUC) were used. A two-sample t test and ANOVA with Bonferroni correction were used to test the significance of differences between parameters. A significant difference between control and patient groups regarding the coefficient of whole-body glucose utilization and AUC C-peptide/AUC glucose ratio (p ≪ 0.001 and p = 0.002, respectively) was observed. The high correlation (r = 0.97) between modeled coefficient of whole-body glucose utilization and numerically calculated AUC C-peptide/AUC glucose ratio related to entire cohort indicated the stability of used method. The short-term four-point glucagon stimulation test allows the numerically calculated AUC C-peptide/AUC glucose ratio and/or the coefficient of whole-body glucose utilization calculated from model to be used to diagnostically identify type 1 diabetic patients.

Automatic Generation of English-Japanese Translation Pattern Utilizing Genetic Programming Technique

Science.gov (United States)

Matsumura, Koki; Tamekuni, Yuji; Kimura, Shuhei

There are a lot of constructional differences in an English-Japanese phrase template, and that often makes the act of translation difficult. Moreover, there exist various and tremendous phrase templates and sentence to be refered to. It is not easy to prepare the corpus that covers the all. Therefore, it is very significant to generate the translation pattern of the sentence pattern automatically from a viewpoint of the translation success rate and the capacity of the pattern dictionary. Then, for the purpose of realizing the automatic generation of the translation pattern, this paper proposed the new method for the generation of the translation pattern by using the genetic programming technique (GP). The technique tries to generate the translation pattern of various sentences which are not registered in the phrase template dictionary automatically by giving the genetic operation to the parsing tree of a basic pattern. The tree consists of the pair of the English-Japanese sentence generated as the first stage population. The analysis tree data base with 50,100,150,200 pairs was prepared as the first stage population. And this system was applied and executed for an English input of 1,555 sentences. As a result, the analysis tree increases from 200 to 517, and the accuracy rate of the translation pattern has improved from 42.57% to 70.10%. And, 86.71% of the generated translations was successfully done, whose meanings are enough acceptable and understandable. It seemed that this proposal technique became a clue to raise the translation success rate, and to find the possibility of the reduction of the analysis tree data base.

Background Trauma exposure and post-traumatic stress disorder (PTSD) increase healthcare utilization in veterans, but their impact on utilization in other populations is uncertain. Objectives To examine the association of trauma exposure and PTSD with healthcare utilization, in civilian primary care patients. Research Design Cross-sectional study. Subjects English speaking patients at an academic, urban primary care clinic. Measures Trauma exposure and current PTSD diagnoses were obtained from the Composite International Diagnostic Interview. Outcomes were nonmental health outpatient and emergency department visits, hospitalizations, and mental health outpatient visits in the prior year from an electronic medical record. Analyses included bivariate unadjusted and multivariable Poisson regressions adjusted for age, gender, income, substance dependence, depression, and comorbidities. Results Among 592 subjects, 80% had ≥1 trauma exposure and 22% had current PTSD. In adjusted regressions, subjects with trauma exposure had more mental health visits [incidence rate ratio (IRR), 3.9; 95% confidence interval (CI), 1.1–14.1] but no other increased utilization. After adjusting for PTSD, this effect of trauma exposure was attenuated (IRR, 3.2; 95% CI, 0.9–11.7). Subjects with PTSD had more hospitalizations (IRR, 2.2; 95% CI, 1.4–3.7), more hospital nights (IRR, 2.6; 95% CI, 1.4–5.0), and more mental health visits (IRR, 2.2; 95% CI, 1.1–4.1) but no increase in outpatient and emergency department visits. Conclusions PTSD is associated with more hospitalizations, longer hospitalizations, and greater mental healthcare utilization in urban primary care patients. Although trauma exposure is independently associated with greater mental healthcare utilization, PTSD mediates a portion of this association. PMID:18362818

Full Text Available Opioids are the most available medicines to get rid of any general severe pain and avoiding of any deleterious sequential that can worsen patient outcomes. Rational prescription of opioid analgesics with respect to the possibility of abuse is a big concern in the medical care costs. Zabol, where is located in eastern part of Iran and has common border with Afghanistanhas the most opioid traffic in the region. In this study the rational prescription of parenteral opioid in Amir-al-Momenin general hospital was investigated. A retrospective drug utilization review was performed on 509 in-patients who received parenteral opioids including Morphine, Pethidin, Pentazocin, Fentanyl, Alfentanil, Sufentanil and Methadone from March 21sttoSeptember 23rd, 2011. Multivariate conditional regression modeling was used to determine independent predictors for daily parenteral opioid consumption. Total daily parenteral opioid consumption was 38.63 DDDs/100bed-days for Morphine, Pethidine and Pentazocin and 84564.78 PFEQs/100bed-days for Fentanyl, Alfentanil and Sufentanil and 766 mg for Methadone. Pethidine was the most frequently prescribed parenteral opioid. Most patients who were prescribed by the intramuscular routes, ordered PRN. Daily parenteral opioid consumption was the highest in the emergency ward whereas it was considered as the lowest in the intensive care unit[ICU]. According to our findings, total daily parenteral opioid consumption was almost high in Amir-al-Momenin Hospital. Unlike to some relevant factors that can effect on the consumption of analgesic opioids like gender, age, drug-drug interaction and etc, we found no rational prescription and consumption in the mentioned hospital.

To estimate the prevalences of common illnesses in Hong Kong adolescents, the sociodemographic and selected risk factors associated with these illnesses, and their health care utilization behavior and attitudes. A cross-sectional questionnaire survey of 3355 participating secondary school students (response rate = 98%). Self-reported 3-month prevalences were obtained for cough/cold/influenza (55.2%), digestive disorders (34.6%), accidental injuries (29.5%), headache/dizziness (23.6%), chronic anxiety/insomnia (20.1%), skin problems (9.5%), asthma (3.8%), liver disease (1.3%), and menstrual pain (13.8% of female students). Self-perceived poor health, smoking, and alcohol consumption were associated with many of these illnesses. Treatment choice depended on the illness suffered (e.g., most students with respiratory problems consulted medical practitioners, whereas most with chronic anxiety/insomnia did not). Many students lacked trust in their doctors, doctor-shopped, relied heavily on self-medication, did not comply with prescribed treatments, would not seek help about medical problems, felt they had insufficient access to health information, and wanted confidential health care. This study examined for the first time the common illnesses and health care utilization patterns of Hong Kong adolescents. Students with chronic anxiety/insomnia were much less likely to seek care, indicating a need for better education on mental health. Efforts to prevent smoking and alcohol consumption among adolescents need to be strengthened. The students' attitudes, poor compliance and help-seeking behaviors suggest suboptimal use of the health care system. Our findings are useful for international comparisons by medical practitioners, health care managers, and researchers.

To describe the referral patterns and utilization of on-site intimate partner violence (IPV) services in both inpatient and outpatient settings at a large urban children's hospital. Retrospective review of case records from IPV victims referred to an on-site IPV counselor between September 2005 and February 2010. Descriptive statistics were used to examine IPV victim demographics, number of referrals per hospital department, referral source (type of staff member), time spent by IPV counselor for initial consultation, and services provided to IPV victims. A total of 453 unique referrals were made to the IPV counselor: 81% were identified by universal screening and 19% by risk-based screening. Thirty-six percent of IPV victims were referred from primary care clinics; 26% from inpatient units; 13% from outpatient subspecialty clinics; 12.5% from the emergency department; 5% from the Child Protection Program; and 4% were employee self-referrals. Social workers generated the most referrals (55%), followed by attending physicians (17%), residents (13%), nurses (7%), and other individuals (self-referrals) (4%). The median initial IPV intervention required 42 minutes. Supportive counseling and safety planning were the services most often utilized by IPV victims. IPV screening can be successfully integrated in both inpatient and outpatient settings by a multidisciplinary group of hospital staff. Most referrals were generated by universal screening outside of the primary care setting. IPV victims generally desired supportive counseling and safety planning over immediate housing relocation. Many IPV screening opportunities were missed by using verbal screening alone. Copyright © 2013 Elsevier Ltd. All rights reserved.

To examine clinical and demographic characteristics of a population-based cohort of patients with uterine carcinosarcoma (UCS), to assess access to treatment and survival patterns. Surveillance, Epidemiology and End Results database was queried for patients diagnosed in 1999-2010 and treated with surgery with or without adjuvant radiation therapy (aRT). The Kaplan-Meier method was used to estimate survival functions, and Cox proportional hazards regression - to analyze the effect of covariates on survival. 2342 patients were eligible. African Americans presented with more advanced AJCC stages than other races (35.4% vs. 29.1%; pAfrican Americans vs. others, and women diagnosed in 1999-2004 vs. in 2005-2010, received aRT at a similar rate: 36.5% vs. 39.9% (p=NS), and 39.5% vs. 38.9% (p=NS), respectively. There was a trend towards higher aRT utilization among patients younger than 65 vs. older (41.4% vs. 37.5%; paRT group: 42 vs. 22 (paRT group. African Americans were more likely to present with later stage disease and die of UCS than non-African Americans. Age and stage, but not race, influenced receipt of aRT. Patients treated more recently survived longer. Copyright © 2016 Elsevier Inc. All rights reserved.

Severe malnutrition and wasting are considered hallmarks of advanced malignant disease, and clinical research into anorexia-cachexia therapy and nutritional support for cancer patients is ongoing. However, information on typical dietary intakes and food choices for this population is notably lacking; proposed therapies for anorexia and wasting are not framed within the context of current intake. The objective of the study was to characterize the food intake patterns of patients with advanced cancer. Patients with advanced cancer (n = 151) recruited from a regional cancer center and palliative-care program completed a 3-d dietary record a mean (+/-SD) 8 +/- 7 mo before death. Food items were categorized according to macronutrient content and dietary use and subsequently entered into cluster analysis. Wide variations in intakes of energy (range: 4-53 kcal . kg body wt(-1) . d(-1); x +/- SD: 25.1 +/- 10.0 kcal . kg body wt(-1) . d(-1)) and protein (range: 0.2-2.7 g . kg body wt(-1) . d(-1); x +/- SD: 1.0 +/- 0.4 g . kg body wt(-1) . d(-1)) were observed. Even the subjects with the highest intakes had a recent history of weight loss, which suggests that the diets of those persons were consistently inadequate for weight maintenance. Cluster analysis found 3 dietary patterns that differed in food choice and caloric intake. Low intakes and a high risk of weight loss were associated with decreased frequency of eating and dietary profiles with little variety and unusually high proportions of liquids. These data provide a glimpse into dietary habits toward the end of life. Unique dietary patterns were found in this nutritionally vulnerable patient population.

The objective of this retrospective study is to analyze ictal patterns observed during continuous Video-EEG monitoring in patients with temporal lobe epilepsy (TLE) due to unilateral hippocampal sclerosis (HS), and to correlate these EEG patterns to temporal pole abnormalities observed on magnetic resonance imaging exams. We analyzed 147 seizures from 35 patients with TLE and unilateral HS. Ictal patterns were classified and correlated to signal abnormalities and volumetric measures of the temporal poles. Volume differences over 10% were considered abnormal. The most frequent type of ictal pattern was rhythmic theta activity (RTA), encountered in 65.5% of the seizures. Rhythmic beta activity (RBA) was observed in 11% of the seizures, localized attenuation in 8%, interruption of epileptiform discharges in 6%, repetitive discharges in 5.5%, and rhythmic delta activity (RDA) in 4%. Sixty-six percent of the patients presented signal abnormalities in the temporal pole that were always ipsilateral to the HS. Sixty percent presented significant asymmetry of the temporal poles consisting of reduced volume that was also always ipsilateral to HS. Although patients with RTA as the predominant ictal pattern tended to present asymmetry of temporal poles (p=0.305), the ictal EEG pattern did not correlate with temporal pole asymmetry or signal abnormalities. RTA is the most frequent initial ictal pattern in patients with TLE due to unilateral HS. Temporal pole signal changes and volumetric reduction were commonly found in this group of patients, both abnormalities appearing always ipsilateral to the HS. However, neither temporal pole volume reduction nor signal abnormalities correlated with the predominant ictal pattern, suggesting that the temporal poles are not crucially involved in the process of epileptogenesis.

Traditional Chinese medicine (TCM) is commonly provided to cancer patients, however, the patterns of prescriptions for this type of medicine in Taiwan are unclear. This study aimed to evaluate the use of traditional Chinese medicine products in colon cancer patients post-surgery in Taiwan and to research patterns of TCM. This was a cross-sectional study of newly diagnosed colon cancer patients who received surgery between 2004 and 2008 identified from the National Health Insurance Research Database of Taiwan. The prescription patterns and reasons for the use of TCM for colon cancer were analyzed. The results showed that "symptoms, signs and ill-defined conditions" (23.3%) and diseases of the digestive system (16.9%) were the most common reasons for using Chinese herbal medicine. Xiang-sha-liu-jun-zi-tang (7.1%), Bu-zhong-yi-qi-tang (4.3%), Jia-wei-xiao-yao-san (4.1%), Shen-Ling-Bai-Zhu-San (3.7%), Ban-Xia-Xie-Xin-Tang (3.4%), Gui-pi-tang (2.4%), Ping-Wei-San (2.4%), Gan-Lu-Yin (2.0%), Bao-He-Wan (1.9%), and Zhen-Ren-Huo-Ming-Yin (1.8%) were the most commonly prescribed single Chinese herbal formulae (CHF) for colon cancer patients post-surgery. Hedyotis diffusa Willd (Bai Hua She She Cao) (5.1%) and Scutellaria barbata (Ban Zhi Lian )(4.8%) were the most commonly prescribed single Chinese herbs. This study identified patterns of TCM use in colon cancer patients post-surgery in Taiwan. The herbal ingredients were most commonly used for stimulate ghrelin secretion to increase food intake and had potential anti-tumor effect. However, further research is required to evaluate any beneficial effects which could identify leads for the development of new treatment strategies using TCM. Copyright © 2014 Elsevier Ireland Ltd.

Due to its increasing incidence and its major contribution to healthcare costs, cancer is a major public health problem in the United States. The impact across different services is not well documented and utilization of emergency departments (ED) by cancer patients is not well characterized. The aim of our study was to identify factors that can be addressed to improve the appropriate delivery of quality cancer care thereby reducing ED utilization, decreasing hospitalizations and reducing the related healthcare costs. The New Jersey State Inpatient and Emergency Department Databases were used to identify the primary outcome variables; patient disposition and readmission rates. The independent variables were demographics, payer and clinical characteristics. Multivariable unconditional logistic regression models using clinical and demographic data were used to predict hospital admission or emergency department return. A total of 37,080 emergency department visits were cancer related with the most common diagnosis attributed to lung cancer (30.0%) and the most common presentation was pain. The disposition of patients who visit the ED due to cancer related issues is significantly affected by the factors of race (African American OR=0.6, p value=0.02 and Hispanic OR=0.5, p value=0.02, respectively), age aged 65 to 75years (SNF/ICF OR 2.35, p value=0.00 and Home Healthcare Service OR 5.15, p value=0.01, respectively), number of diagnoses (OR 1.26, p value=0.00), insurance payer (SNF/ICF OR 2.2, p value=0.02 and Home Healthcare Services OR 2.85, p value=0.07, respectively) and type of cancer (breast OR 0.54, p value=0.01, prostate OR 0.56, p value=0.01, uterine OR 0.37, p value=0.02, and other OR 0.62, p value=0.05, respectively). In addition, comorbidities increased the likelihood of death, being transferred to SNF/ICF, or utilization of home healthcare services (OR 1.6, p value=0.00, OR 1.18, p value=0.00, and OR 1.16, p value=0.04, respectively).

The authors used the Dissociative Disorders Interview Schedule to compare structured interview symptom patterns in a general population sample (N= 502) and a sample of patients with clinical diagnoses of dissociative identity disorder (N= 303). Based on the Trauma Model, the authors predicted that the patterns would be similar in the 2 samples and that symptom scores would be higher in participants reporting childhood sexual abuse in both samples. They predicted that symptom scores would be higher among women with dissociative identity disorder reporting sexual abuse than among women in the general population reporting sexual abuse, with the clinical sample reporting more severe abuse. These predictions were supported by the data. The authors conclude that symptom patterns in dissociative identity disorder are typical of the normal human response to severe, chronic childhood trauma and have ecological validity for the human race in general.

, there have been several reports of focal elevations of FDOPA utilization in brain of patients with Parkinson's disease (PD), all based on reference tissue methods. To investigate this phenomenon further, we used voxel-wise steady-state kinetic analysis to search for regions of elevated FDOPA utilization (K......; ml g(-1) min(-1)) and steady-state trapping (V(d); ml g(-1)) in a group of well-characterized patients with early, asymmetric PD, who were contrasted with an age-matched control group. Subtraction of the population mean parametric maps revealed foci of increased FDOPA utilization K (+25...

The 'Evolution Canyons' I and II in Israel are model habitats to study adaptation and speciation of bacteria in the environment. These canyons represent similar ecological replicates, separated by 40 km, with a strongly sun-exposed and hot 'African' south-facing slope (SFS) vs. a cooler and mesic-lush 'European' north-facing slope (NFS). Previously, among 131 Bacillus simplex isolates, distinct genetic lineages (ecotypes), each specific for either SFS or NFS, were identified, suggesting a temperature-driven slope-specific adaptation. Here, we asked whether the ecological heterogeneity of SFS vs. NFS also affected carbon utilization abilities, as determined using the Biolog assay. Contrary to expectation, a correlation between substrate utilization patterns and the ecological origin of strains was not found. Rather, the patterns split according to the two major phylogenetic lineages each of which contain SFS and NFS ecotypes. We conclude that traits related to the general energy metabolism, as far as assessed here, are neither shaped by the major abiotic features of 'Evolution Canyon', namely solar radiation, temperature, and drought, nor by the soil characteristics. We further conclude that some traits diverge rather neutrally from each other, whereas other, more environmentally related traits are shaped by natural selection and show evolutionary convergence.

Full Text Available Nonalcoholic fatty liver disease (NAFLD is considered the most common liver disease in the world. Dietary habits have a significant impact on the biological and physical profile of patients and increase the risk of NAFLD. The overall pattern of diet intake is more associated with health outcomes than nutrients. The aim of this study was to evaluate the nutritional profile and the dietary patterns of Lebanese NAFLD patients and compare it with controls. During this study; 112 NAFLD Lebanese adult patients (55 men and 57 women; and 110 controls (44 men and 66 women were recruited. Dietary intake was evaluated by two 24-h recalls and a semi-quantitative 90-item food frequency questionnaire. Dietary patterns were determined by factor analysis. Results from the study demonstrated that 40% of cases belonged to the high fruit group as compared to 30% following a high meat; fast food dietary pattern. Both groups increased the odds of NAFLD by four-fold (p < 0.05. The traditional diet decreases the odds by 33% after adjustment with the covariables. The high fruit diet group was, as with the high meat, fast food dietary pattern, the main potential risk factor for NAFLD in Lebanese patients.
