Indian Rheumatology Association guidelines for the management of ANCA associated vasculitis.

Background: The ACR in 2021 and the EULAR in 2022 published recommendations for management of ANCA-associated vasculitis. Given the differences in the demographic, clinical profiles, and the socio-economic realities between various countries, there is a need for development of guidelines for the management of AAV for less economically developed regions of the world.

Methods: These guidelines were made following the GRADE methodology.

Evaluating different models of maternal stress on stress-responsive systems in prepubertal mice.

Introduction: Maternal adversity during pregnancy influences neurodevelopment in human and model animal offspring. Adversity can result from stressors coming from many different directions ranging from environmental to nutritional and physiological to immune (e.g.

Viscoelastic response of confined powder under large strain oscillations, characterized by its noise temperature.

We report a study on granular matter with and without small additions of silicon oil, under low-frequency and large amplitude oscillatory shear strain under constant normal pressure, by running experiments with a rotational rheometer with a cup-and-plate geometry. We analysed the expansion with the Chebyshev polynomials of the orthogonal decomposition of stress-strain Lissajous-Bowditch loops. We found the onset of the strain amplitude for the yielding regime indicated a regime change from filament-like structures of grains to grain rearrangements for the dry granulate and from oscillations to the breaking and regeneration of liquid bridges for wet granulates.

Glucocorticoid regulation of diurnal spine plasticity in the murine ventromedial prefrontal cortex.

The ventromedial prefrontal cortex (vmPFC) regulates fear acquisition, fear extinction, mood, and HPA axis function. Multiple brain regions exhibit time-of-day dependent variations in learning, long term potentiation (LTP), and dendritic morphology. Glucocorticoids have been implicated in the regulation of dendritic structure in the context of stress.

Sex differences in autonomic responses to stress: implications for cardiometabolic physiology.

Chronic stress is a significant risk factor for negative health outcomes. Furthermore, imbalance of autonomic nervous system control leads to dysregulation of physiological responses to stress and contributes to the pathogenesis of cardiometabolic and psychiatric disorders. However, research on autonomic stress responses has historically focused on males, despite evidence that females are disproportionality affected by stress-related disorders.

The Effects of Chronic Variable Stress and Photoperiod Alteration on the Hypothalamic-Pituitary-Adrenal Axis Response and Behavior of Mice.

The hypothalamic-pituitary-adrenal (HPA) axis mediates the physiological response to stressors and also synchronizes different physiological systems to environmental cues. Changes in day length (i.e.

Sex Differences in Acute Neuroendocrine Responses to Stressors in Rodents and Humans.

Sex differences in the neuroendocrine response to acute stress occur in both animals and humans. In rodents, stressors such as restraint and novelty induce a greater activation of the hypothalamic-pituitary-adrenal axis (HPA) in females compared to males. The nature of this difference arises from steroid actions during development (organizational effects) and adulthood (activational effects).

Pericardial Mesothelioma Presenting as Constrictive Pericarditis.

This case report presents a 60-year-old gentleman with a significant smoking history and possible asbestos exposure who was referred to the emergency department for atrial fibrillation with a rapid ventricular rate and symptoms of heart failure. Labs showed normal brain natriuretic peptide and troponin I. His echocardiography finding suggested constrictive pericarditis with an ejection fraction of 60%.

Surgeon specialty does not influence outcomes of hiatal hernia repair.

Background: Hiatal hernia repair is commonly performed by both general and thoracic surgeons. The present study examined differences in approach, setting, and outcomes by specialty for hiatal hernia repair.

Methods: Adults undergoing hiatal hernia repair were identified in the 2012-2019 American College of Surgeons National Surgical Quality Improvement Program.

Management of Connective Tissue Disease-related Interstitial Lung Disease.

Purpose Of Review: This review aims to collate current evidence on the screening, diagnosis, and treatment of various connective tissue disease (CTD)-associated interstitial lung diseases (CTD-ILD) and present a contemporary framework for the management of such patients. It also seeks to summarize treatment outcomes including efficacy and safety of immunosuppressants, anti-fibrotics, and stem cell transplantation in CTD-ILD.

Recent Findings: Screening for ILD has been augmented by the use of artificial intelligence, ultra-low dose computerized tomography (CT) of the chest, and the use of chest ultrasound.

SARS-CoV-2-associated haemorrhagic encephalitis mimicking Herpes encephalitis.

Although acute encephalopathy is quite commonly seen in patients of SARS-CoV-2 infection, encephalitis characterised by brain inflammation is relatively rare. Encephalitis caused by Herpes simplex type 1 is the most common cause of identified sporadic encephalitis, and early diagnosis and prompt treatment can prevent the devastating outcome. In this brief communication, we report a case of SARS-CoV-2 associated haemorrhagic encephalitis mimicking herpes encephalitis.

Impact of angiotensin II receptor antagonism on the sex-selective dysregulation of cardiovascular function induced by in utero dexamethasone exposure.

In utero exposure to glucocorticoids in late gestation programs changes in cardiovascular function. The objective of this study was to determine the degree to which angiotensin II mediates sex-biased changes in autonomic function as well as basal and stress-responsive cardiovascular function following in utero glucocorticoid exposure. Pregnant rats were administered the synthetic glucocorticoid dexamethasone (Dex; 0.

Androgens and Their Role in Regulating Sex Differences in the Hypothalamic/Pituitary/Adrenal Axis Stress Response and Stress-Related Behaviors.

Androgens play a pivotal role during development. These gonadal hormones and their receptors exert organizational actions that shape brain morphology in regions controlling the stress regulatory systems in a male-specific manner. Specifically, androgens drive sex differences in the hypothalamic/pituitary/adrenal (HPA) axis and corresponding hypothalamic neuropeptides.

Physical Examination for the Detection of Pulmonary Hypertension: A Systematic Review.

We performed a systematic review to determine whether the physical examination can reliably assist in the diagnostic approach for patients suspected of having pulmonary hypertension (PH). Using dual extraction, two investigators independently searched PubMed, Ovid MEDLINE, Cochrane Library, and Embase for studies that compared physical examination findings with a right heart catheterization, from inception until July 10, 2021. We obtained data from four studies that evaluated physical examination findings in patients receiving a right heart catheterization to diagnose PH.

The efficiency of F-FDG-PET/CT in the assessment of tumor response to preoperative chemoradiation therapy for locally recurrent rectal cancer.

Background: Locally recurrent rectal cancer (LRRC) remains a major problem after curative resection of primary rectal cancer. A noninvasive, prognostic biomarker with which to accurately evaluate disease status and assess the treatment response is critically needed to optimize treatment plans. This study assesses the effectiveness of PET/CT evaluation of preoperative chemoradiation therapy (CRT) in patients with LRRC.

Validation of Hindi version of the Pittsburg Sleep Quality Index.

Background: Sleep quality is poorly understood in the Indian population. Lack of a suitable tool to assess sleep quality in Hindi language is the main reason behind this. Pittsburg sleep quality index (PSQI) is widely used in different population groups to assess subjective sleep quality over last one month.

Fully Bio-Based Elastomer Nanocomposites Comprising Polyfarnesene Reinforced with Plasma-Modified Cellulose Nanocrystals.

This article proposes a process to prepare fully bio-based elastomer nanocomposites based on polyfarnesene and cellulose nanocrystals (CNC). To improve the compatibility of cellulose with the hydrophobic matrix of polyfarnesene, the surface of CNC was modified via plasma-induced polymerization, at different powers of the plasma generator, using a -β-farnesene monomer in the plasma reactor. The characteristic features of plasma surface-modified CNC have been corroborated by spectroscopic (XPS) and microscopic (AFM) analyses.
