BACKGROUND: Pets are major contributors of endotoxin in homes, but whether they influence endotoxin association with respiratory outcomes is unclear. OBJECTIVE: To examine whether exposure and sensitization to dog and cat modify the relationship between endotoxin exposure and asthma and wheeze. METHODS: We analyzed data from 6,051 participants in the 2005-2006 National Health and Nutrition Examination Survey (NHANES). House dust from bedroom floor and bedding was evaluated for endotoxin and for dog (Canis familiaris 1) and cat (Feline domesticus 1) allergens...

Vitamin D deficiency is especially prevalent in pregnant women and children. Our recent study demonstrated that vitamin D deficiency in early life disturbed testicular development. This study investigated the effects of vitamin D deficiency in early life on prostatic hyperplasia in middle-aged mice. In control group, dams and their male pups were fed with standard-chow diets. In VDD group, dams were fed with vitamin D deficient (VDD) diets throughout pregnancy and lactation. After weaning, male pups continued to be fed with VDD diets...

ALX/FPR2 is a G-protein-coupled receptor that has multiple binding partners, including the endogenous lipid mediators resolvin D1 (RvD1), lipoxin A4 (LXA4 ), and the Ca2+ -dependent phospholipid-binding protein Annexin A1. Previous studies demonstrated that RvD1 activates ALX/FPR2 to resolve salivary gland inflammation in the NOD/ShiLtJ mouse model for Sjögren's syndrome. Moreover, mice lacking the ALX/FPR2 display an exacerbated salivary gland inflammation in response to lipopolysaccharide. Additionally, activation of ALX/FPR2 has been shown to be important for regulating antibody production in B cells...

BACKGROUND: Postural drainage is used primarily in infants with cystic fibrosis from diagnosis up to the moment when they are mature enough to actively participate in self-administered treatments. However, there is a risk of gastroesophageal reflux associated with this technique.This is an update of a review published in 2015. OBJECTIVES: To compare the effects of standard postural drainage (15º to 45º head-down tilt) with modified postural drainage (15º to 30º head-up tilt) with regard to gastroesophageal reflux in infants and young children up to six years old with cystic fibrosis in terms of safety and efficacy...

Immune checkpoint inhibitors have demonstrated efficacy across many cancer types in numerous clinical trials. However, because patients with preexisting autoimmune disease were excluded from these seminal trials, there are serious gaps in knowledge regarding the efficacy-and in particular the safety-of these transformative agents in patients with autoimmune disease. The safety of immune checkpoint inhibitors in this population has been an important concern, since these agents unleash immune activation, a potentially dangerous situation for patients with already heightened and aberrant immune function...

SIGNIFICANCE: Ocular myasthenia gravis is a localized form of myasthenia gravis, which is a postsynaptic disorder of the neuromuscular junction that causes fluctuating weakness of extraocular muscles resulting from autoimmune mechanisms. In women with myasthenia, changes in sex hormone levels and administration of corticosteroids can trigger or worsen symptoms of myasthenia gravis. PURPOSE: To describe a case of seronegative ocular myasthenia gravis whose first symptom appeared a day after in vitro fertilization procedure...

PURPOSE: Prolonged work in the heat may exacerbate the rise in core temperature on the next work day, especially in older workers who display impairments in whole-body heat loss that increase body heat storage and core temperature relative to young adults during heat stress. We therefore evaluated whether whole-body heat loss in older adults was impaired on the day following prolonged work in the heat. METHODS: Whole-body heat exchange and heat storage were assessed in nine older (53-64 years) males during three, 30-min bouts of semi-recumbent cycling at fixed rates of metabolic heat production (150 (Ex1), 200 (Ex2), 250 Wm (Ex3)), each separated by 15-min recovery, in hot-dry conditions (40°C, 20% relative humidity), immediately prior to (Day 1), and on the day following (Day 2), a prolonged, work simulation (~7...

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease associated with significant morbidity and mortality. Current diagnostic criteria based on the presence of fixed airflow obstruction and symptoms do not integrate the complex pathological changes occurring within the lung and they do not define different airway inflammatory patterns. The current management of COPD is based on 'one size fits all' approach and does not take the importance of heterogeneity in COPD population into account. The available treatments aim to alleviate symptoms and reduce exacerbation frequency but do not alter the course of the disease...

It has not yet been possible to quantify dose-related health risks attributable to indoor dampness or mold (D/M), to support the setting of health-related limits for D/M. An overlooked target for assessing D/M is moisture in building materials, the critical factor allowing microbial growth. A search for studies of quantified building moisture and occupant health effects identified three eligible studies. Two studies assessed associations between measured wall moisture content and respiratory health in the UK...

Background Aspirin-exacerbated respiratory disease (AERD), also known as Samter's triad or aspirin (ASA)-intolerant asthma, affects 7% of asthmatics and has a higher prevalence in those with chronic rhinosinusitis and concomitant nasal polyposis. ASA desensitization with daily ASA therapy is a uniquely beneficial treatment for this disease entity and has been shown to have a significant impact on symptom scores, polyp disease, and need for systemic corticosteroids. However, no long-term studies have demonstrated whether or not ASA therapy remains safe and beneficial for these patients beyond 5-10 years...

Corrosion and release of nickel ions from biomedical alloys are well documented, but little is still known about the effects of released nickel ions on cellular function with recurrent inflammatory challenges. Evidence suggests Ni(II) ions amplify LPS-induced secretion of several pro-inflammatory cytokines from monocytes. Exacerbating the inflammatory response, hyperglycemic conditions also affect monocytic function. This study investigated how Ni(II) and hyperglycemic conditions, both singly and in combination, alter monocyte proliferation, mitochondrial activity, inflammatory responses, and differentiation...

Background: Trichotillomania (TTM) is an impulse control disorder characterized by repetitive hair pulling/trimming. Barbering behavior (BB) observed in laboratory animals is proposed as a model of TTM. The neurobiological basis of TTM is unclear, but involves striatal hyperactivity and hypoactivation of the prefrontal cortex. Methods: In this study, we evaluated the BB in knockout mice for the inducible isoform of nitric oxide synthase (NOS2KO) and the consequences of silencing this enzyme in PC12 cell differentiation...

Cardiovascular disease remains a major medical and socioeconomic burden in developed and developing countries and will increase with an aging and increasingly sedentary society. Many vascular diseases and atherosclerotic vascular disease, in particular, are essentially inflammatory disorders, involving multiple cell types. Communication between these cells is initiated and sustained by a complex network of cytokines and their receptors. The interleukin (IL)-20 family members, IL-19, IL-20, IL-22, and IL-24, initiate, sustain, and drive the progression of vascular disease...

Hemicrania continua (HC) is a rare primary headache disorder, characterized by persistent unilateral pain associated with cranial autonomic symptoms and prompt response to indomethacin. While migrainous features (including aura) have been recognized in cluster headache, there have been only single reports of HC with aura. Here, we report the case of a 53-year-old man with constant right-sided headache and superimposed exacerbations to severe pain lasting for several hours. Secondary etiologies were excluded, and a diagnosis of HC was established after prompt and complete response to treatment with indomethacin...

BACKGROUND: Previous models of Hospital at Home (HAH) for COPD exacerbation (ECOPD) were limited by the lack of a reliable prognostic score to guide patient selection. Approximately 50% of hospitalised patients have a low mortality risk by DECAF, thus are potentially suitable. METHODS: In a non-inferiority randomised controlled trial, 118 patients admitted with a low-risk ECOPD (DECAF 0 or 1) were recruited to HAH or usual care (UC). The primary outcome was health and social costs at 90 days...
