OBJECTIVES: To evaluate the influence of examiner experience on the accuracy of sonographic weight estimation and to further analyze examiners' individual learning curves. METHODS: In this multicenter study, 4613 sonographic weight estimations performed by 18 examiners at the beginning of their ultrasound training were included. To assess the effect of experience on the accuracy of weight estimation, a multivariable mixed regression model analysis was performed, with percentage error and absolute percentage error as outcome variables and the examiner, the examiner's experience (number of examinations), birth weight, gestational age, scan-to-delivery interval, and maternal body mass index as fixed effects and the perinatal center as random intercepts...

BACKGROUND AND AIMS: The efficacy of prophylactic indomethacin for prevention of post-ERCP pancreatitis (PEP) in general patients remains controversial. To address this, we therefore conducted a meta-analysis of clinical trials specifically on rectal indomethacin in prevention of PEP in consecutive patients undergoing ERCP. METHODS: We searched MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials databases to identify randomized, double-blinded, controlled clinical trials on rectal indomethacin in prevention of PEP in consecutive patients undergoing ERCP...

The calculation of heart rate variability (HRV) is a popular tool used to investigate differences in cardiac autonomic control between population samples. When interpreting effect sizes to quantify the magnitude of group differences, researchers typically use Cohen's guidelines of small (0.2), medium (0.5), and large (0.8) effects. However, these guidelines were originally proposed as a fallback for when the effect size distribution (ESD) was unknown. Despite the availability of effect sizes from hundreds of HRV studies, researchers still largely rely on Cohen's guidelines to interpret effect sizes and to perform power analyses to calculate required sample sizes for future research...

Defense reactions to threatening situations are vital adaptations to stress that protect organisms from injury and ensure survival. We retrospectively investigated the role of peritraumatic dissociation (PD) in the occurrence of severe psychopathology and dissociative patterns of reactions in borderline personality disorder (BPD). We recruited 28 patients with a clinical diagnosis of BPD and 15 healthy controls. The BPD group was divided according to the level of PD (low vs. high): BPD and PD (n = 15) and BPD only (n = 13)...

Some of the main causes of mortality and morbidity among the developed countries - such as the cardiovascular, neurological and oncologic diseases - are deeply associated with modifiable risk factors. Primordial/primary prevention strategies that alter our environment can have an impact on these risk factors. The authors of this Cochrane systematic review sought evidence from randomized controlled trials to study the effect of the size of portions, packages, dishes and cups, as well as their respective formats, on the consumption and selection of food, alcoholic and non-alcoholic beverages and tobacco products...

A case-control study was performed to identify clinical predictors for Middle East respiratory syndrome coronavirus (MERS-CoV) infection among patients with acute febrile illness during the nosocomial outbreak. Patients with MERS-CoV were more likely to have monocytosis with normal white blood cell (WBC) count and lower C-reactive protein (CRP) level. Simple laboratory data such as complete blood counts (CBC) with differential count could be a useful marker for the prediction of MERS and triage at the initial presentation of acute febrile patients in outbreak setting...

The timing of puberty onset varies greatly among individuals, and much of this variation is modulated by genetic factors. This study aimed to identify the kisspeptin receptor (KISS1R) gene variations and to investigate the associations between these variations and central precocious puberty (CPP). Korean girls with CPP (n = 194) and their healthy controls (n = 99) were included in this study. The entire coding region and the exon-intron boundaries (exon 1 through 5) of the KISS1R gene were directly sequenced...

The association between vitamin D levels and nonalcoholic fatty liver disease (NAFLD) has been recognized. However, few studies showed independent associations between vitamin D deficiency and NAFLD after a sex-related adjustment for metabolic factors. We aimed to study whether vitamin D deficiency is an independent risk factor of NAFLD even after controlling for metabolic syndrome and visceral fat in both sexes. In this cross-sectional study, 7,514 Korean adults (5,278 men, 2,236 women) participated in a health check-up program...

Despite the rapidly increasing prevalence of non-alcoholic fatty liver disease (NAFLD) in type 2 diabetes (T2D), few treatment modalities are currently available. We investigated the hepatic effects of the novel thiazolidinedione (TZDs), lobeglitazone (Duvie) in T2D patients with NAFLD. We recruited drug-naïve or metformin-treated T2D patients with NAFLD to conduct a multicenter, prospective, open-label, exploratory clinical trial. Transient liver elastography (Fibroscan®; Echosens, Paris, France) with controlled attenuation parameter (CAP) was used to non-invasively quantify hepatic fat contents...

Behçet's disease (BD) is a complex chronic relapsing inflammatory disorder of unknown etiology. Alterations of the tumor necrosis factor (TNF) expression related to the polymorphic alleles of TNF gene may implicate a pathogenetic role in increased activity of this cytokine in BD. A current study aimed at investigating the possible association between BD and its clinical features in Iranian Azeri Turks with two functional TNF-α gene polymorphisms (at the positions of -238 and -857). A total number of 166 Iranian subjects were enrolled into two different groups; patients with BD (n = 64), and ethnically matched healthy controls (n = 101)...

The paper continues the series of publications from the International Nuclear Workers Study cohort (INWORKS) that comprises 308,297 workers from France, the United Kingdom and the United States, providing 8.2 million person-years of observation from a combined follow-up period (at earliest 1944 to at latest 2005). These workers' external radiation exposures were primarily to photons, resulting in an estimated average career absorbed dose to the colon of 17.4 milligray. The association between cumulative ionizing radiation dose and cancer mortality was evaluated in general relative risk models that describe modification of the excess relative risk (ERR) per gray (Gy) by time since exposure and age at exposure...

A carcinogen-induced premalignant oral lesion model that progresses to oral cancer was used to examine the impact of blocking PD-1 on cytokine expression and on progression of lesions to cancer. The results of this study show increased production of IL-2 and the inflammatory cytokines IL-6, IL-17 and TNF-α by spleen cells of lesion-bearing mice that were treated with PD-1 antibody for one week compared to cytokine production by spleen cells of lesion-bearing mice treated with control antibody. Production of IFN-γ increased at 3 weeks of PD-1 antibody treatment, although production of the other Th1 and inflammatory mediators declined...

OBJECTIVE: With the advent of regenerative/cell therapy for Parkinson's disease (PD), (18)F-FDOPA has drawn new attention as a biomarker of the therapeutic that cannot be evaluated with radiopharmaceuticals for dopamine transporter. Since most previous (18)F-FDOPA PET studies were carried out many years ago with a PET scanner of lower resolution and with (18)F-FDOPA of low specific activity synthesized from (18)F-F2, we used a newer PET/CT scanner with a high-resolution condition and (18)F-FDOPA synthesized from (18)F-F(-) to re-evaluate this technique on normal subjects and patients with PD, together with D2 receptor imaging with (11)C-raclopride (RAC)...

In maladaptive respects, perfectionism reflects an individual's concern over making mistakes and doubting the quality of his or her own actions excessively, which would affect one's emotion. However, little is known about the neural mechanisms associated with the perfectionism and negative affect. In this study, voxel-based morphometry was performed to identify the brain regions underlying individual differences in perfectionism, which was measured by the Chinese Frost Multidimensional Perfectionism Scale (CFMPS), in a large sample of nonclinical young adults...

Lipoprotein (a) [Lp(a)] is an independent risk factor for cardiovascular disease. There are currently limited therapeutic options to lower Lp(a) levels. L-Carnitine has been reported to reduce Lp(a) levels. The aim of this study was to compare the effect of L-carnitine/simvastatin co-administration with that of simvastatin monotherapy on Lp(a) levels in subjects with mixed hyperlipidemia and elevated Lp(a) concentration. Subjects with levels of low-density lipoprotein cholesterol (LDL-C) >160 mg/dL, triacylglycerol (TAG) >150 mg/dL and Lp(a) >20 mg/dL were included in this study...
