A high rate of patients lost to follow-up is a common problem in orthopedic trauma surgery. This adversely affects the ability to produce accurate clinical outcomes research. The purpose of this project was to (1) evaluate the rate of loss to follow-up at an academic level I trauma center; (2) identify the patient-reported reasons for loss to follow-up; and (3) evaluate the efficacy of a routine patient callback program. All patients who underwent surgery in the orthopedic trauma division of the University of Virginia Medical Center from April 1, 2014, to September 30, 2014, and did not complete their postoperative clinic follow-up were analyzed...

PURPOSE: To predict photon percentage depth dose (PDD) from profile due to a change in flattened (FF) and flattening-filter-free (FFF) beam quality. METHODS: 6MV photon beam PDDs and profiles in a 3D water tank (3DW) and profiles in an ionization chamber array (ICP) were collected for different field sizes and depths with FF and FFF beams in a Versa HD (Elekta Ltd.). The energy was adjusted by changing the bending magnet current (BMC) ±15% from the clinical beam (6MV) in 5% increments...

Fear of gaining weight after quitting cigarette smoking is a major barrier to smoking cessation among women. Distress tolerance, which refers to one's ability and willingness to tolerate physical and emotional discomfort, predicts successful behavior change. Novel interventions rooted in Acceptance and Commitment Therapy (ACT) have emerged that aim to increase distress tolerance and engagement in values-oriented behavior. In this study, we developed a 9-week, group-based distress tolerance intervention for weight concern in smoking cessation among women (DT-W)...

Whether well-documented patterns of mental health comorbidity with adolescent combustible cigarette use extend to e-cigarette use is unclear. Demonstrating associations between e-cigarette and combustible cigarette use with mental health symptomatology across adolescence may be important for promoting accurate perceptions of populations at risk for and potential consequences of tobacco product use. Adolescents (N=2460; mean age at baseline=14.1; 53.4% female; 44.1% Hispanic) who had never previously used combustible or e-cigarettes were assessed at baseline, and 6- and 12-month follow-ups in Los Angeles, CA (2013-2014)...

BACKGROUND: The first prospective observational study of uterus transplantation was initiated in 2013 with live donation to 9 women with absolute uterine factor infertility. We explored the medical complications and psychosocial wellbeing of the donors during the first postoperative year. METHODS: Complications were registered and graded according to the Clavien-Dindo (C-D) classification. Symptoms related to the surgery were registered. Data on length of hospital stay, sick leave, socioeconomic parameters and life events were obtained...

The primary goal of conventional endodontic treatment is prevention and/or elimination of apical periodontitis for both mature permanent teeth and immature teeth with an open apex. Besides these goals, the objectives of endodontic treatment of immature teeth include preservation of pulp vitality and often further root maturation. Robust criteria for outcome assessment are an essential determinant for any measure of treatment success for both mature and immature teeth.

PURPOSE: The prevalence of advanced dysplasia and synchronous lesions is particularly high in patients with large, flat colorectal polyps. However, the impact of lifestyle on the development of such polyps is poorly investigated. Hence, this study aims to identify associations between behavioral factors and the occurrence of large, flat colorectal polyps. METHODS: Behavioral factors were retrospectively analyzed in patients with large, flat polyps and control patients with at most one diminutive polyp...

Leukoencephalopathy with thalamus and brainstem involvement and high lactate (LTBL) is a recently described autosomal recessive mitochondrial disease characterized by early onset of neurological symptoms, a biphasic clinical course, and distinctive neuroimaging. Pathogenic variants in the EARS2 gene that encode for mitochondrial glutamyl-tRNA synthetase are responsible for LTBL. Here, we describe the clinical course of an infant diagnosed with an acute crisis of LTBL and severe liver disease. This article illustrates the utility of blood lactate quantification in addition to basic metabolic testing and brain imaging in a child with low tone and poor growth...

Until now, absolute uterine factor infertility has been the major untreatable form of female infertility. Recently, uterus transplantation has proven to be the first successful treatment for absolute uterine factor infertility, with demonstration of live births. Here, live donation uterus transplantation was performed in nine women. 163 cervical biopsies (149 protocol, 14 follow-up) were taken to detect histopathological signs of rejection. Based on experience from animal experiments, we used a three-grade scoring system to evaluate biopsies systematically...

PURPOSE: Open tibial fractures needing soft tissue cover are challenging injuries. Infection risk is high, making treatment difficult and expensive. Delayed skin closure has been shown to increase the infection rate in several studies. We aimed at calculating the direct and indirect cost of treatment, and to determine the effect of delayed skin closure on this cost. METHODS: We reviewed all records of patients treated with a free flap in our institution for an open tibial fracture from 2002 to 2013...

BACKGROUND: Distinct behavioral economic domains, including high perceived drug value (demand) and delay discounting (DD), have been implicated in the initiation of drug use and the progression to dependence. However, it is unclear whether frequent marijuana users conform to a "reinforcer pathology" addiction model wherein marijuana demand and DD jointly increase risk for problematic marijuana use and cannabis dependence (CD). METHODS: Participants (n=88, 34% female, 14% cannabis dependent) completed a marijuana purchase task at baseline...

OBJECTIVE: The tendency to react with fear to anxiety-related sensations (anxiety sensitivity) and the inability to tolerate distressing psychological or physiological states (distress intolerance) are implicated in the comorbidity between affective psychopathology and cannabis use disorders. Emotionally vulnerable cannabis users may be particularly apt to use cannabis to cope with distress, which may both lead to and maintain its problematic use (e.g., dependence, craving). The current study tested a comprehensive model of anxiety sensitivity and distress intolerance as predictors of the number of cannabis dependence symptoms and problems, and severity of cannabis craving following deprivation from cannabis, and the mediating role of cannabis coping motives...

Propionic acid (PPA) is a ubiquitous short-chain fatty acid, which is a major fermentation product of the enteric microbiome. PPA is a normal intermediate of metabolism and is found in foods, either naturally or as a preservative. PPA and its derivatives have been implicated in both health and disease. Whereas PPA is an energy substrate and has many proposed beneficial effects, it is also associated with human disorders involving mitochondrial dysfunction, including propionic acidemia and autism spectrum disorders (ASDs)...

RATIONALE: A previous genome-wide association study (GWAS) in a predominately Caucasian sample of healthy young adults linked greater amphetamine-induced rewarding effects with the rs3784943 G allele of the cadherin 13 (CDH13; i.e., a cell adhesion molecule implicated in neuronal connectivity) gene. This association has not been subsequently examined, nor has it been studied in Asian populations, which may have greater frequencies of the risk allele. OBJECTIVE: The objective of this study was to examine the association of rs3784943 with amphetamine response in a racially heterogeneous sample (37 % Asian) of healthy young adults...

The 2015 European Guidelines on Diagnosis and Treatment of Pulmonary Hypertension are also valid for Germany. The guidelines contain detailed recommendations for the targeted treatment of pulmonary arterial hypertension (PAH). However, the practical implementation of the European Guidelines in Germany requires the consideration of several country-specific issues and already existing novel data. This requires a detailed commentary to the guidelines, and in some aspects an update already appears necessary. In June 2016, a Consensus Conference organized by the PH working groups of the German Society of Cardiology (DGK), the German Society of Respiratory Medicine (DGP) and the German Society of Pediatric Cardiology (DGPK) was held in Cologne, Germany...
