D A Irosh P Fernando
A preliminary model for exploring the pathogenesis of depression that involves genetic and environmental factors is described using a system of linear differential equation. The influence of environmental factors essentially involves random life events, which are modelled using a stochastic differential equation. Different scenarios, including the trajectory of the pathogenesis of depression and immunity, are described by model simulation.

Using data from the National Longitudinal Study of Adolescent to Adult Health, this study examines the relationship between significant changes in neighbourhood poverty during the transition to adulthood and shifts in depressive symptoms. We found that associations between changes in neighbourhood poverty and mental health disappeared after controlling for contemporaneous life course events, specifically transitions associated with intimate relationship building and human capital formation. The exception is a decrease in depressive symptoms for females moving into lower poverty neighbourhoods across the entire transition to adulthood period...

INTRODUCTION: 3-methoxyphencyclidine (3-MeO-PCP) appeared on the illicit drug market in 2011 and is an analogue of phencyclidine, which exhibits anesthetic, analgesic and hallucinogenic properties. In this paper, we report data from a non-fatal intoxication and seven deaths involving 3-MeO-PCP in Sweden during the period March 2014 until June 2016. CASE DESCRIPTIONS: The non-fatal intoxication case, a 19-year-old male with drug problems and a medical history of depression, was found awake but tachycardic, hypertensive, tachypnoeic and catatonic at home...

Numerous studies have reported an association between stress and urolithiasis. Although urinary risk factors have been measured in several of these, compelling evidence of a causal relationship has not been established. A shortcoming is that alterations in single urinary parameters rather than ratios and quotients, which provide a more synergistic risk evaluation, have been measured. Recently, we speculated about a possible association between chronic stress and stone recurrence. This presents an intriguing dichotomy of whether stress causes stones or vice versa, or whether they are linked in a self-propagating stress-stones-stress-recurrence cycle...

We tested the hypothesis that exposure of glut3+/- mice to a ketogenic diet ameliorates autism-like features which includes aberrant behavior and electrographic seizures. We first investigated the life course sex-specific changes in basal plasma-CSF-brain metabolic profile, brain glucose transport/uptake, glucose and monocarboxylate transporter proteins, and ATP in the presence or absence of systemic insulin administration. Glut3+/- male but not female mice (5m of age) displayed reduced CSF glucose/lactate concentrations with no change in brain Glut1, Mct2, glucose uptake or ATP...

CONTEXT: Allopregnanolone is a metabolite from progesterone and a positive modulator of the GABAA receptor. This endogenous steroid may induce negative mood in sensitive women when present in serum levels comparable to the premenstrual phase. Its endogenous isomer, isoallopregnanolone, has been shown to antagonize allopregnanolone effects in experimental animal and human models. OBJECTIVE: The objective was to test whether inhibition of allopregnanolone by treatment with the GABAA modulating steroid antagonist (GAMSA) Sepranolone (UC1010) during the premenstrual phase could reduce symptoms of the premenstrual dysphoric disorder (PMDD)...

Even though rare, mega-fires raging during very dry and windy conditions, record catastrophic impacts on infrastructure, the environment and human life, as well as extremely high suppression and rehabilitation costs. Apart from the direct consequences, mega-fires induce long-term effects in the geomorphological and hydrological processes, influencing environmental factors that in turn can affect the occurrence of other natural hazards, such as floods and mass movement phenomena. This work focuses on the forest fire of 2007 in Peloponnese, Greece that to date corresponds to the largest fire in the country's record that burnt 1773km(2), causing 78 fatalities and very significant damages in property and infrastructure...

BACKGROUND: Patients with stable angina not controlled by monotherapy with nitrates, beta blockers, or calcium channel blockers are often treated with combinations of these drugs. There may be adverse effects from, or contraindications to, the use of combinations. In low risk groups, medical treatment appears to be as good an option as percutaneous transluminal coronary angioplasty in terms of averting myocardial infarction, death, or subsequent revascularization. Revascularization procedures are too costly or inaccessible for many patients in developing countries therefore effective and safe medical treatment is needed...

OBJECTIVE: Gastroesophageal reflux disease (GERD) is a common disease which can cause troublesome symptoms and affect quality of life. In addition to esophageal complications, GERD may also be a risk factor for extra-esophageal complications. Both GERD and coronary artery disease (CAD) can cause chest pain and frequently co-exist. However, the association between GERD and acute myocardial infarction (AMI) remain unclear. The purpose of the study was to compare the incidence of acute myocardial infarction in GERD patients with an age-, gender-, and comorbidity matched population free of GERD...

Taxonomic details of diversity are an essential scaffolding for biology education, yet outdated methods for teaching the tree of life (TOL), as implied by textbook content and usage, are still commonly employed. Here, we show that the traditional approach only vaguely represents evolutionary relationships, fails to denote major events in the history of life, and relies heavily on memorizing near-meaningless taxonomic ranks. Conversely, a clade-based strategy-focused on common ancestry, monophyletic groups, and derived functional traits-is explicitly based on Darwin's "descent with modification," provides students with a rational system for organizing the details of biodiversity, and readily lends itself to active learning techniques...

Large cohort studies suggest that high convective volumes associated with online hemodiafiltration may reduce the risk of mortality/morbidity compared to optimal high-flux hemodialysis. By contrast, intradialytic tolerance is not well studied. The aim of the FRENCHIE (French Convective versus Hemodialysis in Elderly) study was to compare high-flux hemodialysis and online hemodiafiltration in terms of intradialytic tolerance. In this prospective, open-label randomized controlled trial, 381 elderly chronic hemodialysis patients (over age 65) were randomly assigned in a one-to-one ratio to either high-flux hemodialysis or online hemodiafiltration...

Adam Lund, Sheila Turris
Despite the best efforts of event producers and on-site medical teams, there are sometimes serious illnesses, life-threatening injuries, and fatalities related to music festival attendance. Producers, clinicians, and researchers are actively seeking ways to reduce the mortality and morbidity associated with these events. After analyzing the available literature on music festival health and safety, several major themes emerged. Principally, stakeholder groups planning in isolation from one another (ie, in silos) create fragmentation, gaps, and overlap in plans for major planned events (MPEs)...

Recent research proposes that left hemispheric lateralization (HL) may protect against the effects of life events on mental distress. This study extends these findings by examining the protective role of left-HL in the relationship between war threat (missile exposure) and PTSD symptoms. A sample of 186 Israelis, exposed to missile attacks, completed brief scales of self-reported missile exposure, a subjective and a neuropsychological HL measure, and of PTSD symptoms. The sample was split into right-HL and left-HL individuals on both HL measures...

Emergent life events (ELEs)-unexpected stressors disclosed in psychotherapy that have a significant negative impact on the client-commonly occur in community populations of youth and are associated with decreased provider adherence to evidence-based treatment (EBT) in session. The present study extends previous research by examining longer term associations of ELEs with (a) provider adherence to planned EBT practices in subsequent sessions and (b) clinical progress. Data were drawn from the modular EBT condition (MATCH) of the Child STEPs California trial conducted with primarily Latino youth, ages 5-15, who were 54% male (Chorpita et al...

OBJECTIVE: The impact of multiple major life stressors is hypothesized to reduce the probability of resilience and increase rates of mortality. However, this hypothesis lacks strong empirical support because of the lack of prospective evidence. This study investigated whether experiencing multiple major health events diminishes rates of resilience and increases rates of mortality using a large population-based prospective cohort. METHOD: There were n = 1,395 individuals sampled from the Health and Retirement Study (HRS) and examined prospectively from 2 years before 4 years after either single or multiple health events (lung disease, heart disease, stroke, or cancer)...
