The present study examines whether early adolescents' self-efficacy beliefs about anger regulation mediate the relation between parents' self-efficacy beliefs about anger regulation and early adolescents' internalizing and externalizing problems. Participants were 534 early adolescents (T1: M age = 10.89, SD = .70; 50% female), their mothers (n = 534), and their fathers (n = 431). Families were drawn from Colombia, Italy, and the USA. Follow-up data were obtained two (T2) and three (T3) years later. At T1 and T3, parents' self-efficacy beliefs were self-reported and internalizing and externalizing problems were assessed via mothers', fathers', and early adolescents' reports...

Toxicity reduction in wastewaters from small hair care products manufacturing companies using coagulation/flocculation/sedimentation or flotation, membrane separation and powdered activated charcoal adsorption was evaluated. Raw wastewater composition varied widely within and especially between companies, but all exhibited high acute toxicity to Daphnia similis (EC(I)50; 48 h < 0.02-0.33%). Coagulation with aluminum sulfate and polyaluminum chloride aided by cationic or anionic polymers, as well as filtration on ultra (UF) and nanofiltration (NF) membranes efficiently removed turbidity (>99%) and oil and grease (>99%) and all treated samples exhibited similar dissolved organic matter contents...

There is now converging evidence from studies in animals and humans that the medial temporal lobes (MTLs) harbor anatomically distinct processing pathways for object and scene information. Recent functional magnetic resonance imaging studies in humans suggest that this domain-specific organization may be associated with a functional preference of the anterior-lateral part of the entorhinal cortex (alErC) for objects and the posterior-medial entorhinal cortex (pmErC) for scenes. As MTL subregions are differentially affected by aging and neurodegenerative diseases, the question was raised whether aging may affect the 2 pathways differentially...

OBJECTIVE: Non-rechargeable deep brain stimulation (DBS) impulse generators (IG) with a low or empty battery status require surgical IG exchange several years after initial implantation. Complication rates in patients undergoing DBS surgery range from 7.6% to 25.3%. The aim of this study was to investigate the complication rates after IG exchange surgery and to identify risk factors for complications. METHODS: We retrospectively analysed complications following IG exchange surgery from 2008 to 2015 in a single-centre university hospital setting...

Donor factors, in addition to HLA matching status, have been associated with recipient survival in unrelated donor (URD) hematopoietic cell transplantation (HCT), however there is no hierarchical algorithm that weights the characteristics of individual donors against each other in a quantitative manner to facilitate donor selection. The goal of this study was to develop and validate a donor selection score that prioritizes donor characteristics associated with better survival in 8/8 HLA-matched URDs. Two separate patient/donor cohorts, the first receiving HCT between 1999-2011 (n=5952, c1), and the second between 2012-2014 (n=4510, c2) were included in the analysis...

BACKGROUND: Abdominal pain, secondary amenorrhea and abnormal uterine bleeding (AUB) are common gynecologic presentations in adolescence. Rarely this can be associated with an acquired hematometra. Hematometra is a condition of retained blood or clot within the uterus. High dose progestogenic agents in this age group have been implicated in the accumulation of a hematometra without other explanation. CASES: We present 4 cases of hematometra following depomedroxyprogesterone acetate (DMPA) therapy in previously menstruating adolescents...

Invasive aspergillosis (IA) is a life-threatening infection affecting hematologic cancer patients with chemotherapy-induced neutropenia. The diagnosis of IA often relies on the detection of galactomannan (GM) in serum or bronchoalveolar lavage fluid (BAL). Bi-weekly serum GM screening has been proposed for a preemptive therapeutic approach of IA in patients not receiving mold-active prophylaxis. We have analyzed all IA cases among patients with hematologic malignancies and prolonged chemotherapy-induced neutropenia (>14 days) in our institution over a 10-year period (2007-2017)...

BACKGROUND: Understanding the burden of influenza-associated severe acute respiratory infection (SARI) is important for setting national influenza surveillance and vaccine priorities. Estimating influenza-associated SARI rates requires hospital-based surveillance data and a population-based denominator, which can be challenging to determine. OBJECTIVES: We present an application of the World Health Organization's recently developed manual (WHO Manual) including hospital admission survey (HAS) methods for estimating the burden of influenza-associated SARI, with lessons learned to help others calculate similar estimates...

Studies demonstrate that GRM, expressed by >60% of human melanomas, may be a therapeutic target. We performed a phase II trial of 100 mg po bid of riluzole, an inhibitor of GRM1 signaling, in patients with advanced melanoma with the primary endpoint of response rate. Thirteen patients with GRM1-positive tumors were enrolled. No objective responses were observed and accrual was stopped. Stable disease was noted in 6 (46%) patients, with 1 patient on study for 42 weeks. Riluzole was well-tolerated, with fatigue (62%) as the most common adverse event...

BACKGROUND: To review the role of PACAP38 in human models of primary headaches, discuss possible mechanisms of PACAP38-induced migraine, and outline future directions. DISCUSSION: Experimental studies have established PACAP38 as a potent pharmacological "trigger" molecule of migraine-like attacks. These studies have also revealed a heterogeneous PACAP38 migraine response in migraine without aura patients. In addition, findings from brain imaging studies have demonstrated neuronal and vascular changes in migraine patients both ictally and interictally after PACAP38 infusion...

OBJECTIVE: Recently, a benzofuran derivative for the imaging of β-amyloid plaques, 5-(5-(2-(2-(2- 18 F-fluoroethoxy)ethoxy)ethoxy)benzofuran-2-yl)- N-methylpyridin-2-amine ( 18 F-FPYBF-2) has been validated as a tracer for amyloid imaging and it was found that 18 F-FPYBF-2 PET/CT is a useful and reliable diagnostic tool for the evaluation of AD (Higashi et al. Ann Nucl Med, https://doi.org/10.1007/s12149-018-1236-1 , 2018). The aim of this study was to assess the biodistribution and radiation dosimetry of diagnostic dosages of 18 F-FPYBF-2 in normal healthy volunteers as a first-in-man study...

This pilot study aims to improve HPV vaccination for college aged males at a student health center. The first part of the study consisted of a focus group that assessed the barriers and facilitators of HPV vaccination among healthcare providers and clinic staff (N = 16). Providers reported missed opportunities for HPV vaccination. For the second part of the study, providers and staff reviewed medical records of patients ages 18-26 with student health insurance and with < 3 doses of the HPV vaccine at baseline (12/1/2014 to 7/31/2015) and follow-up (12/1/2015 to 7/31/2016)...

PURPOSE: Meniscal tears are common in Kenya, with prevalence rates ranging from 45 to 78% of intracapsular knee pathology. Diagnosis of these injuries relies on the use of both clinical signs and symptoms as well as radiological investigations. In a few instances, radiological detection could be difficult, partly because of variant attachment patterns of the medial meniscal anterior horn. Some of these unusual attachments of the anterior horn of the medial meniscus could even be mistaken for meniscal tears...

Sertoli cells were discovered in the seminiferous tubules by Enrico Sertoli in 1865 (Morgagni 7:31-33, 1865). Intense phagocytosis is, in the context of spermatogenesis cycle, morphologically the most noticeable function of Sertoli cells. In this chapter the major principles of phagocytosis machinery and its specificities in the seminiferous tubules will be briefly reviewed, guidelines of analysis of main phagocytosis steps by confocal and transmission electron microscopy will be described, and a simplified method to assess phagocytosis rate in routine experiments will be given...

The brain-derived neurotrophic factor (BDNF) is a major proliferative agent in the nervous system. Both BDNF-deficiency and perinatal hypoxia represent genetic/environmental risk factors for schizophrenia. Moreover, a decreased BDNF response to birth hypoxia was associated with the disease. BDNF expression is influenced by neuronal activity and environmental conditions such as hypoxia. Thus, it may partake in neuroprotective and reparative mechanisms in acute or chronic neuronal insults. However, the interaction of hypoxia and BDNF is insufficiently understood and the behavioral outcome unknown...

BACKGROUND: Adipokines are peptides secreted from white adipose tissue (WAT), which have been linked to WAT dysfunction and metabolic complications of obesity. We set out to identify novel adipokines in subcutaneous WAT (sWAT) linked to insulin resistance (IR). METHODS: Gene expression was determined by microarray and qPCR in obese and non-obese subjects with varying degree of IR. WAT-secreted and circulating protein levels were measured by ELISA. RESULTS: In sWAT of 80 obese women discordant for IR, 44 genes encoding potential adipose-secreted proteins were differentially expressed...

Some shifts in the gut microbiota composition and its metabolic fingerprints have been associated to Sleeve gastrectomy (SG) and Roux-en-Y Gastric Bypass (RYGB). So far, plasma bile acids have been associated with post-operative glucose improvement and weight loss, but nothing is known about their metabolism in the gut lumen. As bile acids are physiologically transformed by the microbiota into various species, the aim of this work was to study how SG and RYGB-associated dysbiosis impact the bioconversion of bile acids in the intestinal lumen...

Serotonin is a neurotransmitter involved in many psychiatric diseases. In humans, a lack of 5-HT 2B receptors is associated with serotonin-dependent phenotypes, including impulsivity and suicidality. A lack of 5-HT 2B receptors in mice eliminates the effects of molecules that directly target serotonergic neurons including amphetamine derivative serotonin releasers, and selective serotonin reuptake inhibitor antidepressants. In this work, we tested the hypothesis that 5-HT 2B receptors directly and positively regulate raphe serotonin neuron activity...

The majority of colorectal cancer (CRC) arises from precursor lesions known as polyps. The molecular determinants that distinguish benign from malignant polyps remain unclear. To molecularly characterize polyps, we utilized Cancer Adjacent Polyp (CAP) and Cancer Free Polyp (CFP) patients. CAPs had tissues from the residual polyp of origin and contiguous cancer; CFPs had polyp tissues matched to CAPs based on polyp size, histology and dysplasia. To determine whether molecular features distinguish CAPs and CFPs, we conducted Whole Genome Sequencing, RNA-seq, and RRBS on over 90 tissues from 31 patients...
