Amiodarone is one of the most commonly prescribed antiarrhythmic agents in clinical practice owing to its efficacy, even with high toxicity profile. The high iodine content and the prolonged biological half-life of the drug can result in thyroid dysfunction in a high proportion of patients treated with amiodarone even after cessation of amiodarone. Both hypothyroidism and hyperthyroidism are common side effects that mandate regular monitoring of patients with thyroid function tests. Amiodarone-induced hypothyroidism (AIH) is diagnosed and managed in the same way as a usual case of hypothyroidism...

Around 30% of elementary school students with autism spectrum disorder (ASD) are considered minimally verbal, yet there is limited research addressing the needs of this group of students. Several recent studies have demonstrated successful improvement of the communication skills of elementary school students with limited verbal skills. Additionally, there are focused intervention practices that are evidence based and may be useful in targeting communication skills for children with ASD who are minimally verbal...

BACKGROUND: Uric acid (UA), an antioxidant with neuroprotective effects, favorably affects stroke outcome. However, the effect has not been examined in patients treated with edaravone, a frequently used free radical scavenger. We investigated whether the use of edaravone affected the relationship between UA levels and outcome in acute ischemic stroke. METHODS: We retrospectively evaluated 1,114 consecutive ischemic stroke patients with premorbid modified Rankin Scale (mRS) scores <2 admitted within 24 h of onset (mean, 74 years; median UA levels, 333 μmol/L)...

Fabry disease (FD) is a rare, X-linked disorder caused by mutations in the GLA gene encoding the enzyme α-galactosidase A. Complete or partial deficiency in this enzyme leads to intracellular accumulation of globotriaosylceramide (Gb3) and other glycosphingolipids in many cell types throughout the body, including the kidney. Progressive accumulation of Gb3 in podocytes, endothelial cells, epithelial cells, and tubular cells contribute to the renal symptoms of FD, which manifest as proteinuria and reduced glomerular filtration rate leading to renal insufficiency...

A source of debate in the health care priority setting literature is whether to weight health gains to account for equity considerations, such as concern for those with very short life expectancy. This paper reviews the empirical evidence in the published social sciences literature relevant to the following research question: do members of the public wish to place greater weight on a unit of health gain for end-of-life patients than on that for other types of patients? An electronic search of the Social Sciences Citation Index for articles published until October 2017 was conducted, with follow-up of references to obtain additional data...

Skeletal muscle is an endocrine organ that secretes several proteins, which are collectively termed myokines. Although many studies suggest that exercise regulates myokine secretion, the underlying mechanisms remain unclear and all the exercise-dependent myokines have not yet been identified. Therefore, in this study, we attempted to identify novel exercise-dependent myokines by using our recently developed in vitro contractile model. Differentiated C2C12 myotubes were cultured with or without electrical pulse stimulation (EPS) for 24 h to induce cell contraction, and the myokines secreted in conditioned medium were analyzed using a cytokine array...

According to the tissue-specific methylation database (doi: 10.1016/j.gene.2014.09.060), methylation at CpG locus cg03096975 in EML2 has been preliminarily proven to be specific to brain tissue. In this study, we enlarged sample size and developed a technique for identifying brain tissue in aged samples. Combined Bisulfite Restriction Analysis-for EML2 (COBRA-EML2) technique was established and validated in various organ samples obtained from 108 autopsies. In addition, this technique was also tested for its reliability, minimal DNA concentration detected, and use in aged samples and in samples obtained from specific brain compartments and spinal cord...

Childhood sexual abuse (CSA) is a worldwide problem with severe long-term consequences. A history of CSA can impact the childbearing experience of mothers and fathers; affecting their mental health, parenting skills and compromising infant development. Nonetheless, the perinatal period offers huge opportunity for intervention and hope. This literature review collates evidence for perinatal psychosocial interventions targeting both mothers and fathers who are survivors of CSA. Publications dating from 1970 to June 2016 were searched using Medline, Maternity and Infant Health, PsychINFO, PsychArticles, PubMed and the International Bibliography of the Social Sciences (IBSS)...

When visual information about an object's distance is obscured, but its retinal size visible, the object's physical size is ambiguous to vision; however, additional proprioceptive distance information permits physical size to be estimated when grasping the object, but perceptual size estimates remain inaccurate, adding to that evidence for distinct visual pathways for perception and action.

Several studies support a plausible association of human exposure to polychlorinated biphenyls (PCBs) with type 2 diabetes mellitus. However, little is known about the potential link between circulating PCBs levels in early pregnancy and development of gestational diabetes mellitus (GDM). Here, we conducted a prospective study with a nested case-control design to determine the association of PCB exposure in early pregnancy with GDM risk. Concentrations of selected so-called 'indicator PCBs' were determined in sera of women in the first trimester of pregnancy via gas chromatography - high resolution mass spectrometry...

BACKGROUND: Recent reviews suggest that the way in which surgeons prepare for a procedure (warm up) can affect performance. Operating lists present a natural experiment to explore this phenomenon. The aim was to use a routinely collected large data set on surgical procedures to understand the relationship between case list order and operative performance. METHOD: Theatre lists involving the 35 procedures performed most frequently by senior surgeons across 38 private hospitals in the UK over 26 months were examined...

Halogen- and chalcogen-based σ-hole interactions have recently received increased interest in non-covalent organocatalysis. However, the closely related pnictogen bonds have been neglected. In this study, we introduce conceptually simple, neutral, and monodentate pnictogen-bonding catalysts. Solution and in silico binding studies, together with high catalytic activity in chloride abstraction reactions, yield compelling evidence for operational pnictogen bonds. The depth of the σ holes is easily varied with different substituents...

Importance: Skin cancer is the most common type of cancer in the United States. Although invasive melanoma accounts for only 2% of all skin cancer cases, it is responsible for 80% of skin cancer deaths. Basal and squamous cell carcinoma, the 2 predominant types of nonmelanoma skin cancer, represent the vast majority of skin cancer cases. Objective: To update the 2012 US Preventive Services Task Force (USPSTF) recommendation on behavioral counseling for the primary prevention of skin cancer and the 2009 recommendation on screening for skin cancer with skin self-examination...

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a global epidemic associated with increased health expenditure, and low quality of life. Many non-genetic risk factors have been suggested, but their overall epidemiological credibility has not been assessed. METHODS: We searched PubMed to capture all meta-analyses and Mendelian randomization studies for risk factors of T2DM. For each association, we estimated the summary effect size, its 95% confidence and prediction interval, and the I2 metric...

Disease outbreaks can have substantial impacts on wild populations, but the often patchy or anecdotal evidence of these impacts impedes our ability to understand outbreak dynamics. Recently however, a severe disease outbreak occurred in a group of very well-studied organisms-sea stars along the west coast of North America. We analyzed nearly two decades of data from a coordinated monitoring effort at 88 sites ranging from southern British Columbia to San Diego, California along with 2 sites near Sitka, Alaska to better understand the effects of sea star wasting disease (SSWD) on the keystone intertidal predator, Pisaster ochraceus...

Despite evidence that the ability to taste is weakened by obesity and can be rescued with weight loss intervention, few studies have investigated the molecular effects of obesity on the taste system. Taste bud cells undergo continual turnover even in adulthood, exhibiting an average life span of only a few weeks, tightly controlled by a balance of proliferation and cell death. Recent data reveal that an acute inflammation event can alter this balance. We demonstrate that chronic low-grade inflammation brought on by obesity reduces the number of taste buds in gustatory tissues of mice-and is likely the cause of taste dysfunction seen in obese populations-by upsetting this balance of renewal and cell death...
