OBJECTIVES: Associations between parental occupational pesticide exposure and childhood acute lymphoblastic leukemia (ALL) vary across studies, likely due to different exposure assessment methodologies. METHODS: We assessed parental occupational pesticide exposure from the year before pregnancy to the child's third year of life for 669 children diagnosed with ALL and 1021 controls. We conducted expert rating using task-based job modules (JM) to estimate exposure to pesticides among farmer workers, gardeners, agricultural packers, and pesticide applicators...

This work aims to characterize personal exposure of firefighters to polycyclic aromatic hydrocarbons (PAHs) in non-fire work environments (fire stations), and assesses the respective risks. Eighteen PAHs (16 considered by USEPA as priority pollutants, dibenzo[a,l]pyrene and benzo[j]fluoranthene) were monitored in breathing zones of workers at five Portuguese fire stations during a normal shift. The obtained levels of PAHs fulfilled all existent occupational exposure limits as well as air quality guidelines with total concentrations (ΣPAHs) in range of 46...

BACKGROUND: Bipolar Disorder (BD) is characterized by impairments in psychosocial functioning with occupational disability being one of the most significant. Depression and neurocognitive deficits are features of BD most commonly associated with poor occupational functioning (OF). Few studies have examined these features over an extended period of time focusing on distinct aspects of work functioning. METHODS: This longitudinal study included 273 adults with bipolar I disorder (N=173), bipolar II disorder (N=69), and bipolar not otherwise specified (N=31)...

PURPOSE OF REVIEW: We aim to review recent updates on the epidemiology of chronic kidney disease (CKD). RECENT FINDINGS: Recent analyses from the National Health and Nutritional Examination survey describe the temporal trend in CKD prevalence in US adults. The overall prevalence of estimated glomerular filtration rate less than 60 ml/min/1.73 m increased from 4.8% in 1988-1994 to 6.9% in 2003-2004, but has since stabilized at 6.4-6.9% up to 2011-2012. Prevalence of CKD stages 1-4 has also stabilized at ∼14% of adults since 2003-2004...

The effects of climate change on animal populations may be shaped by habitat characteristics at both micro- and macro-habitat level, however, empirical studies integrating these two scales of observation are lacking. As analyses of the effects of climate change commonly rely on data from a much larger scale than the microhabitat level organisms are affected at, this mismatch risks hampering progress in developing understanding of the details of the ecological and evolutionary responses of organisms and, ultimately, effective actions to preserve their populations...

With rapid development of nanotechnology and nanomaterials, nanosafety has attracted wide attention in all fields related to nanotechnology. As well known, a grand challenge in nanomaterial applications is their biocompatibility. It is urgent to explore effective strategies to control the unintentional effects. Although many novel methods for the synthesis of biocompatible and biodegradable nanomaterials are reported, the control strategy of nanotoxicity remains in its infancy. It is urgent to review the archived strategies for improving nanomaterial biocompatibility to clarify what we have done and where we should be...

Introduction Operational stress describes individual behavior in response to the occupational demands and tempo of a mission. The stress response of military personnel involved in combat and peace-keeping missions has been well-described. The spectrum of effect on medical professionals and support staff providing humanitarian assistance, however, is less well delineated. Research to date concentrates mainly on shore-based humanitarian missions. Problem The goal of the current study was to document the pattern of operational stress, describe factors responsible for it, and the extent to which these factors impact job performance in military and civilian participants of Continuing Promise 2011 (CP11), a ship-based humanitarian medical mission...

The aim of this study was to examine the influence of demographic, environmental and occupational factors as well as behavioural characteristics of intercity bus drivers, on their crash involvement risk. A total number of 107 intercity bus drivers from Tehran, Iran were participated in the study. Logistic regression model suggested that smokers, those who drive during night to morning, less experienced drivers as well as those who operate older buses are more likely to be involved in crashes. In addition, one unit increase in the weekly driving hours might significantly increase the drivers' crash involvement risk...

Hepatitis B virus (HBV) infection is a major public health problem with over two billion people infected globally. Occupationally exposed persons are at high risk of HBV infection. Apart from medical personnel, there is dearth of information as regards the prevalence and awareness of HBV among occupationally exposed persons in the country. This study was designed to determine the levels of HBV awareness and prevalence of HBV infection among hairdressers in Ibadan, Nigeria. Hairdressers and teachers (unmatched controls) in four local government areas in Ibadan were tested for HBV infection using ELISA technique...

Jason E Sammons, Amor Khachemoune
Axillary hyperhidrosis is characterized by an increased amount of sweat production, localized to the armpits, to compensate for environmental conditions and to control thermoregulation. It affects about 3.12% of the US population. It has a significant effect on one's psychological and physical health, as well as one's occupational life. The objective of this paper is to review the epidemiology, clinical presentation, pathophysiology, histology, and genetics, and management and treatment of axillary hyperhidrosis...

OBJECTIVE: In car crashes, the passenger compartment deceleration influences the occupant loading significantly. Hence, it is important to consider how each structural component deforms in order to control the passenger compartment deceleration. In frontal impact tests, the passenger compartment deceleration depends on the energy absorption property of the front structures. However, at this point in time there are few papers describing the component's quantitative contributions on the passenger compartment deceleration...

JS-001 is the first monoclonal antibody (mAb) against programmed cell death protein-1 (PD-1) approved by the China Food and Drug Administration (CFDA) into the clinical trails. To date, however, no pre-clinical pharmacological and pharmacokinetic (PK) data are available. In this study, we investigated the efficacy of JS-001 and conducted a preclinical PK study, including the monitoring of anti-drug antibodies (ADAs). We found that JS-001 specifically bound to PD-1 antigen with an EC50 of 21 nmol/L, and competently blocked the binding of PD-1 antigen to PD-L1 and PD-L2 with IC50 of 3...

A microscopic (Hamiltonian-based) method for the quantum statistics of bosonic excitations in a two-mode magnon system is developed. Both the exchange and the dipole-dipole interactions, as well as the Zeeman term for an external applied field, are included in the spin Hamiltonian, and the model also contains the nonlinear effects due to parallel pumping and four-magnon interactions. The quantization of spin operators is achieved through the Holstein-Primakoff formalism, and then a coherent magnon state representation is used to study the occupation magnon number and the quantum statistical behaviour of the system...

Francesco R Sebastiani, Harry Dym, Tarun Kirpalani
The goal of an infection control program is to provide a safe working environment for dental health care personnel and their patients. Practitioners can achieve this by adopting measures that reduce health care-associated infections among patients and occupational exposures among dental health care personnel. It is crucial for all dental practitioners to be up to date on current Centers for Disease Control and Prevention guidelines, equipment, and techniques for proper infection control. Continuous evaluation of infection control practices is important...

REVIEW
John E Harris
Chemical-induced depigmentation of the skin has been recognized for more than 75 years, first as an occupational hazard but then extending to those using household commercial products as common as hair dyes. Since their discovery, these chemicals have been used therapeutically in patients with severe vitiligo to depigment their remaining skin and improve their appearance. Because chemical-induced depigmentation is clinically and histologically indistinguishable from nonchemically induced vitiligo, and because these chemicals appear to induce melanocyte autoimmunity, this phenomenon should be known as "chemical-induced vitiligo," rather than less accurate terms that have been previously used...

Lili Wei, Xuemei Zhao, Ruanlin Wang, Yuejun Fu, Baofeng Chai, Aihua Liang
Analysis of transcriptome revealed that a membrane occupation and recognition nexus (MORN) repeat protein-encoding gene of Euplotes octocarinatus (Eo-morn-9-31) was a candidate for programmed +1 ribosomal frameshifting (+1 PRF). In this study, a dual-luciferase assay was performed to detect its expression. The result showed that the MORN repeat protein (Eo-MORN-9-31) could be produced by the +1 PRF event during the process of translation in yeast and the frameshifting efficiency was about 4-5%. We further confirmed its reality by western blot and mass spectrometry...

Invasive plants can negatively affect native species, however, the strength, direction, and shape of responses may vary depending on the type of habitat alteration and the natural history of native species. To prioritize conservation of vulnerable species, it is therefore critical to effectively predict species' responses to invasive plants, which may be facilitated by a framework based on species' traits. We studied the population and community responses of small mammals and changes in habitat heterogeneity across a gradient of cheatgrass (Bromus tectorum) cover, a widespread invasive plant in North America...
