Hyperglycemia-triggered lipid peroxidation destabilizes STAT4 and impairs anti-viral Th1 responses in type 2 diabetes.

Patients with type 2 diabetes (T2D) are more susceptible to severe respiratory viral infections, but the underlying mechanisms remain elusive. Here, we show that patients with T2D and coronavirus disease 2019 (COVID-19) infections, and influenza-infected T2D mice, exhibit defective T helper 1 (Th1) responses, which are an essential component of anti-viral immunity. This defect stems from intrinsic metabolic perturbations in CD4 T cells driven by hyperglycemia.

Validation of the English version of the Autism-Spectrum Quotient in an English-speaking Singaporean sample.

The Autism-Spectrum Quotient (AQ) measures the degree of autistic traits in clinical and non-clinical samples and has been validated in various countries and languages. However, the AQ has not been validated in Singapore, an Asian country whose population speaks predominantly English. Although previous validation studies have examined the distribution of scores, internal consistency, test-retest reliability and construct, convergent and discriminant validities in Asian countries using translated versions of the AQ and generally shown a suitable structure of the AQ, other studies testing cultural differences of the AQ have provided inconsistent results about whether differences exist in scores between Western and Asian samples.

Neurogenesis-dependent antidepressant-like activity of Hericium erinaceus in an animal model of depression.

Background: Depression is a severe neuropsychiatric disorder that affects more than 264 million people worldwide. The efficacy of conventional antidepressants are barely adequate and many have side effects. Hericium erinaceus (HE) is a medicinal mushroom that has been reported to have therapeutic potential for treating depression.

Activating mutations in BRAF disrupt the hypothalamo-pituitary axis leading to hypopituitarism in mice and humans.

Germline mutations in BRAF and other components of the MAPK pathway are associated with the congenital syndromes collectively known as RASopathies. Here, we report the association of Septo-Optic Dysplasia (SOD) including hypopituitarism and Cardio-Facio-Cutaneous (CFC) syndrome in patients harbouring mutations in BRAF. Phosphoproteomic analyses demonstrate that these genetic variants are gain-of-function mutations leading to activation of the MAPK pathway.

Voluntarily Postponing Testing Is Associated with Lower Performance on the Pediatric Board Certifying Examinations.

Objective: To investigate whether postponing certification testing, either voluntarily or involuntarily, affects a candidate's performance on pediatric certifying examinations.

Study Design: Both general pediatrics (GP) and pediatric subspecialty (PS) examination candidates were included in the study. Candidates were classified into 3 groups based on time since the completion of training: no delay (<12 months), short delay (12-24 months), and long delay (≥24 months).

Do Genetic Susceptibility Variants Associate with Disease Severity in Early Active Rheumatoid Arthritis?

Objective: Genetic variants affect both the development and severity of rheumatoid arthritis (RA). Recent studies have expanded the number of RA susceptibility variants. We tested the hypothesis that these associated with disease severity in a clinical trial cohort of patients with early, active RA.

Predicting the risk of rheumatoid arthritis and its age of onset through modelling genetic risk variants with smoking.

The improved characterisation of risk factors for rheumatoid arthritis (RA) suggests they could be combined to identify individuals at increased disease risks in whom preventive strategies may be evaluated. We aimed to develop an RA prediction model capable of generating clinically relevant predictive data and to determine if it better predicted younger onset RA (YORA). Our novel modelling approach combined odds ratios for 15 four-digit/10 two-digit HLA-DRB1 alleles, 31 single nucleotide polymorphisms (SNPs) and ever-smoking status in males to determine risk using computer simulation and confidence interval based risk categorisation.

The protective effect of alcohol on developing rheumatoid arthritis: a systematic review and meta-analysis.

Objectives: Our aim was to establish whether alcohol protects against RA development and to determine whether this effect is influenced by alcohol dose, duration and serological status through systematically reviewing the literature and undertaking a meta-analysis.

Methods: We searched Medline/EMBASE (1946 to July 2012) using the terms rheumatoid arthritis.mp or arthritis, rheumatoid/ and alcohol.

Investigation of rheumatoid arthritis susceptibility genes identifies association of AFF3 and CD226 variants with response to anti-tumour necrosis factor treatment.

Background: Anti-tumour necrosis factor (anti-TNF) therapy has proved to be highly successful in treating rheumatoid arthritis (RA), although 30-40% of patients have little or no response. The authors hypothesise that this may be genetically determined. In other complex diseases, susceptibility genes have been shown to influence treatment response.

Comparison of attitudes between Generation X and Baby Boomer veterinary faculty and residents.

Understanding the characteristics and preferences of the different generations in the veterinary workforce is important if we are to help optimize current and future veterinary schools and teaching hospitals. The purpose of this study was to compare the attitudes of different generations of veterinary faculty and those of faculty and house officers. A survey administered to faculty and house officers asked respondents to identify their level of agreement with a series of statements addressing work and lifestyle issues and feedback preferences.
