BACKGROUND: Identifying factors that precipitate and maintain post-traumatic stress symptoms (PTSS) after birth is important to inform clinical and research practice; yet, prospective longitudinal studies on the predictors of PTSS are limited. This study aimed to determine the pregnancy and postpartum factors associated with PTSS at 4-6 weeks and 6-months postpartum. METHOD: A systematic sample of 950 pregnant women were recruited from three maternity hospitals in Turkey...

BACKGROUND: An increasing number and proportion of cancer patients with apparently localised disease are treated with chemotherapy and radiation therapy in contemporary oncology practice. In a pilot study of radiation-induced sarcoma (RIS) patients, we demonstrated that chemotherapy was associated with a reduced time to development of RIS. We now present a multi-centre collaborative study to validate this association. METHODS: This was a retrospective cohort study of RIS cases across five large international sarcoma centres between 1 January 2000 to 31 December 2014...

BACKGROUND: Alcoholic hepatitis (AH) is one of the most severe forms of alcoholic liver disease. Recently, a histologic scoring system for predicting prognosis in this patient cohort was proposed as Alcoholic Hepatitis Histologic Score (AHHS). We aimed to assess interobserver variability in recognizing histologic features of AH, and the effect of this variability on the proposed AHHS categories. DESIGN: Hematoxylin-eosin and trichrome stained slides from 32 patients diagnosed with AH with liver biopsies within 1 month of presentation (2000-2015), were reviewed by 5 pathologists including 3 liver pathologists and 2 gastrointestinal (GI) pathologists masked to the clinical findings or outcome...

BACKGROUND: Emerging evidence shows that serum carcinoembryonic antigen (CEA) levels may modestly be increased in non-neoplastic conditions such as cardiometabolic diseases, which are increasingly being seen as inflammatory diseases. Leukocyte count is widely evaluated marker of inflammation in clinical practice and a useful predictor of cardiometabolic disease. In this study, we aimed to determine the relationship between serum CEA levels and leukocyte counts in Korean adults. METHODS: This cross-sectional study included a total of 19 834 individuals enrolled from a health promotion center between November 2006 and July 2010...

As adolescents spend many hours a day in school, it is crucial to examine the ways in which therapeutic practices in schools promote their well-being. This longitudinal pilot study examined the contribution of school-based psychodrama group therapy to the self-concept dimensions and perceived loneliness of 40 Israeli adolescents (aged 13-16, 60% boys) in public middle schools. From a process-outcome perspective, we also examined the understudied trajectory of adolescents' in-session behaviours (process variables) and its associations with changes in their self-concepts and loneliness (outcome variables)...

BACKGROUND: Occupational physicians (OPs) have complex relationships with employees, employers, and the general public. OPs may have simultaneous obligations towards third parties, which can lead to variable conflicts of interests. Among the various studies of ethical issues related to OPs, few have focused on the Korean OPs. The aim of the present survey was to investigate the ethical contexts, the practical resolutions, and the ethical principles for the Korean OPs. METHODS: An email with a self-administered questionnaire was sent to members of the Korean Society of Occupational and Environmental Medicine, comprising 150 specialists and 130 residents...

Model comparisons in the behavioral sciences often aim at selecting the model that best describes the structure in the population. Model selection is usually based on fit indices such as AIC or BIC, and inference is done based on the selected best-fitting model. This practice does not account for the possibility that due to sampling variability, a different model might be selected as the preferred model in a new sample from the same population. A previous study illustrated a bootstrap approach to gauge this model selection uncertainty using two empirical examples...

BACKGROUND: Understanding the extent to which current antibiotic prescribing behaviour is influenced by clinicians' historical patterns of practice will help target interventions to optimize antibiotic use in long-term care. Our objective was to evaluate whether clinicians' historical prescribing behaviours influence the start, prolongation and class selection for treatment with antibiotics in residents of long-term care facilities. METHODS: We conducted a retrospective cohort study of all physicians who prescribed to residents in long-term care facilities in Ontario between Jan...

To determine the extent to which specific neuropsychological measures are in common use around the world for the assessment of children who are candidates for epilepsy surgery. As part of the work of the International League Against Epilepsy Pediatric Surgical Task Force, a survey was developed and distributed online. The survey consisted of questions related to demographics, training experience, general practice, and specific measures used and at what frequency. Seventy-eight clinicians with an average of 13...

BACKGROUND: With the alarming rise in antibiotic resistance in African countries, the need for a surveillance system in the region has become pressing. The rapid expansion of data networks makes it possible to set up healthcare applications that can be both cost-efficient and effective. Large data sets are available for assessment of current antibiotic resistance among Ethiopian patients. Based on the data-presentation, a practical approach is proposed on how diagnostic laboratories can participate remedial action against antibiotic resistance in Ethiopia...

While conventional random forest regression (RFR) virtual screening models appear to have excellent accuracy on random held-out test sets, they prove lacking in actual practice. Analysis of 18 historical virtual screens showed that random test sets are far more similar to their training sets than are the compounds project teams actually order. A new, cluster-based "realistic" training/test set split, which mirrors the chemical novelty of real-life virtual screens, recapitulates the poor predictive power of RFR models in real projects...

Authorship is a central element of scientific research carrying a variety of rewards and responsibilities, and while various guidelines exist, actual author contributions are often ambiguous. Inconsistent or limited contributions threaten to devalue authorship as intellectual currency and diminish authors' responsibility for published content. Researchers have assessed author contributions in the medical literature and other research fields, but similar data for the field of ecological research are lacking...

(no author information available yet)
Asymptomatic microscopic hematuria is an important clinical sign of urinary tract malignancy. Asymptomatic microscopic hematuria has been variably defined over the years. In addition, the evidence primarily is based on data from male patients. However, whether the patient is a man or a woman influences the differential diagnosis of asymptomatic microscopic hematuria, and the risk of urinary tract malignancy (bladder, ureter, and kidney) is significantly less in women than in men. Among women, being older than 60 years, having a history of smoking, and having gross hematuria are the strongest predictors of urologic cancer...

The use of point-of-care ultrasound (US) in the clinical setting has undergone massive growth, although its incorporation into training and practice is variable. Surgeons are interested in using point-of-care US and can incorporate it effectively into clinical practice. However, the current state of point-of-care US training in general surgery is inadequate. The Accreditation Council for Graduate Medical Education introduced the Milestones Project to evaluate resident and fellow performance. Emergency medicine is the only specialty with a point-of-care US milestone...

47,XXY (Klinefelter Syndrome) is associated with a spectrum of complex clinical needs that are associated with variable physical, neurocognitive and psychosocial aspects. For patients and families affected by this sex chromosome trisomy, navigation of health care services is difficult due to lack of 47,XXY awareness among many health care providers and little evidence to support endocrine and additional treatment plans. While endocrine management of androgen deficiency has been the mainstay of treatment for patients from puberty through adulthood, testosterone replacement, alone, fails to mitigate many symptoms and issues...

Very little is known about the effects of specific practice on motor learning of predictive balance control during novel bipedal gait. This information could provide an insight into how the direction and magnitude of predictive errors during acquisition of a novel gait task influence transfer of balance control, as well as yield a practice protocol for the restoration of balance for those with locomotor impairments. This study examined the effect of a variable practice paradigm on transfer of a novel asymmetric gait pattern in able-bodied individuals...

OBJECTIVE: Reference intervals are widely used decision-making tools in laboratory medicine, serving as health-associated standards to interpret laboratory test results. Numerous studies have shown wide variation in reference intervals, even between laboratories using assays from the same manufacturer. Lack of consistency in either sample measurement or reference intervals across laboratories challenges the expectation of standardized patient care regardless of testing location. Here, we present data from a national survey conducted by the Canadian Society of Clinical Chemistry (CSCC) Reference Interval Harmonization (hRI) Working Group that examines the variation in laboratory reference sample measurements, as well as pediatric and adult reference intervals currently used in clinical practice across Canada...
