Introduction: Osteoporosis is a common yet underdiagnosed condition that increases fracture risk and disability. It is particularly prevalent in individuals with musculoskeletal and neurological disorders due to factors like immobility and disuse. Despite its impact, awareness of osteoporosis remains low, especially in this high-risk population.

Objective: Brivaracetam (BRV), a third-generation anti-seizure medication (ASM) offers strong conformational receptor domain binding, faster blood brain barrier (BBB) permeability and better tolerability making it potential therapeutic option as an initial line or initial line add-on strategy for focal onset seizure (FoS). The following study was planned to further understand the role and relevance of BRV in the real world settings of India.

Method: This was a multicentric, cross-sectional, and non-interventional study conducted in patients with FoS across India.

Article Synopsis
  • Hemiplegic shoulder pain (HSP) is a common complication in stroke survivors that can hinder rehabilitation and recovery, and suprascapular nerve block (SSNB) is an effective treatment option.
  • A study involving six stroke patients showed significant improvements in pain levels and shoulder function after undergoing ultrasound-guided SSNB, particularly in overall pain scores and passive range of motion.
  • While patients showed improvement in pain and some functional aspects, not all showed gains in disability measures, indicating that while SSNB is beneficial, it may need to be part of a broader rehabilitation strategy.

Chemical insecticides (organophosphates and pyrethroids) in the form of IRS (Indoor Residual Sprays) and LLINs (Long Lasting Insecticidal Nets) are the cornerstone for vector control, globally. However, their incessant use has resulted in widespread development of resistance in mosquito vectors, warranting continuous monitoring and investigation of the underlying mechanisms of resistance. Here, we identified a previously uncharacterized- Cub and Sushi Domain containing Insecticide Resistance (CSDIR) protein and generated evidence for its role in mediating insecticide resistance in the Anopheles stephensi.

  • Chronic non-healing ulcers are persistent skin wounds that fail to heal within a normal timeframe due to underlying health issues, significantly impacting rehabilitation and quality of life.
  • A case series involving eight wounds from six patients utilized platelet-rich fibrin (PRF) treatment, with weekly applications leading to monitored healing progress using metrics like PUSH scores and wound size.
  • Results showed varying healing rates, with complete wound closure in three cases, and an overall improvement in patients' functional independence by nearly 16% during their hospital stay, indicating PRF is a promising treatment option for these challenging wounds.

Article Synopsis
  • - The study assessed asthma control and COPD severity among patients in outpatient departments across India while also evaluating treatment adequacy and associated risk factors.
  • - Analyzed data from a survey involving 5,311 respiratory disease patients showed that many had poorly controlled asthma (7.4%) and severe COPD, with a significant portion not receiving any medication.
  • - Key risk factors for poorly controlled asthma included rain wetting and gastroesophageal reflux disease, highlighting a major treatment gap for these conditions.

To estimate the prevalence and study the clinical presentation of mild cognitive impairment (MCI), assess its outcome in terms of cognition and quality of life, identify factors for reversion to baseline, and compare these factors in the modifiable and nonmodifiable risk factor groups. Individuals aged >50 years with memory/cognitive complaint(s) were screened using the Mini-Cog over 1 year (August 2018-August 2019). Those meeting the criteria for MCI were enrolled, and risk factors (modifiable and nonmodifiable) were noted.

Article Synopsis
  • The black-legged tick, Ixodes scapularis, is a key vector for Lyme disease and other human pathogens, with its midgut playing a critical role in blood digestion and pathogen exposure.
  • Researchers used a systems biology approach, including RNA and protein sequencing, to study the changes in tick midgut gene expression and proteins during various stages of blood feeding and digestion.
  • The study identified 2,726 differentially expressed transcripts and 449 proteins; some genes were explored as potential vaccine targets, with gene knockdowns showing negative effects on tick physiology, suggesting new strategies for tick control.

In recent years, regulatory agencies have raised concerns about the presence of potentially carcinogenic substances in certain formulations of Angiotensin Receptor Blockers (ARBs). Specifically, nitrosamines and azido compounds have been identified in some ARB products. Nitrosamines are known to have carcinogenic properties and are associated with an increased risk of neoplasms.

Fundamental data analysis assists in the evaluation of critical questions to discern essential facts and elicit formerly invisible evidence. In this article, we provide clarity into a subtle phenomenon observed in cancer incidences throughout the time of the COVID-19 pandemic. We analyzed the cancer incidence data from the American Cancer Society [1].

This study was designed to assess both the quality and cost aspects of various branded and generic formulations of angiotensin receptor blockers, specifically Irbesartan, Losartan Potassium, Olmesartan Medoxomil, Telmisartan, and Valsartan. The collected samples underwent distinct quality evaluations using the methods outlined in different global Pharmacopoeias (British Pharmacopoeia/European Pharmacopoeia, Indian Pharmacopoeia and United States Pharmacopoeia). These drugs were characterized using Fourier-Transform Infrared Spectroscopy and Nuclear Magnetic Resonance techniques, while their quality and concentration were analysed using High Performance Liquid Chromatography.

Hair loss (alopecia) has a multitude of causes, and the problem is still poorly defined. For curing alopecia, therapies are available in both natural and synthetic forms; however, natural remedies are gaining popularity due to the multiple effects of complex phytoconstituents on the scalp with fewer side effects. Evidence-based hair growth promotion by some plants has been reported for both traditional and advanced treatment approaches.

Ticks can transmit various viral, bacterial, and protozoan pathogens and are therefore considered vectors of medical and veterinary importance. Despite the growing burden of tick-borne diseases, research on ticks has lagged behind insect disease vectors due to challenges in applying genetic transformation tools for functional studies to the unique biology of ticks. Genetic interventions have been gaining attention to reduce mosquito-borne diseases.

Article Synopsis
  • - Stroke survivors often experience auditory processing difficulties and hearing loss, which can hinder communication with healthcare workers and affect rehabilitation outcomes.
  • - A pilot study comparing 50 stroke patients to 50 age and sex-matched controls found that stroke patients had a significantly higher mean hearing loss (44.0 dB) compared to controls (36.1 dB).
  • - The study suggests that sensorineural hearing loss is more common and severe in stroke patients, highlighting the need for auditory screening in rehabilitation guidelines to better support recovery.
