Alzheimer's disease is a complex neurodegenerative disease characterized by progressive decline in cognitive function and behaviour. Ginger is the rhizome of the plant Zingiber officinale Roscoe, has been an important ingredient of many Ayurveda formulations to treat neurological disorders. The present study aims to estimate the variation of 6-gingerol content in nine different ginger samples collected from Manipur, India, investigate the neuroprotective potential of the most potent ginger sample against scopolamine-induced cognitively impaired mice, and validate the therapeutic claim by molecular docking analysis.

Rotavirus is a leading cause of severe diarrheal disease in infants and young children worldwide. Vaccination offers the best protection against this disease, and two rotavirus vaccines were developed in India and included in its routine immunization program. The Government of India's decision to adopt this intervention was supported by a solid base of evidence from clinical trials, as well as substantial research regarding rotavirus disease burden and the potential health and economic value of immunization.

Article Synopsis
  • - The study aimed to clarify and standardize the varying terminologies used for the time between tooth avulsion and replantation, recognizing that differences in terms could affect prognosis.
  • - A thorough review identified 92 studies, categorizing terminology into five groups, with most accurate explanations linked to those discussing the total time of dry and wet conditions surrounding the tooth.
  • - The expert consensus, reached through a Delphi study, strongly supported the term "total extra-alveolar period," which effectively describes both the nonphysiologic and physiologic conditions affecting tooth prognosis after avulsion.

Article Synopsis
  • A study was conducted to evaluate the effects of receiving the inactivated influenza vaccine (IIV) and SARS-CoV-2 vaccine at the same time compared to getting them separately among healthcare workers.
  • Results showed that those who received both vaccines together had a lower rise in SARS-CoV-2 antibodies 1 month after vaccination, although this difference was not significant after 6 months.
  • Overall, the concomitant vaccination did not seem to significantly affect the long-term immune response, suggesting that more research is needed to clarify these findings.

Background And Objectives: Rising hypertension from inadequate detection, noncompliance with treatment, and poor control presents a major public health challenge. Previously, adopting the strategy of self-monitoring of blood pressure (SMBP) showed better hypertension detection, control, and medication adherence. However, evidence from India is scarce.

  • In 2018, the Navi Mumbai Municipal Corporation launched a typhoid vaccine campaign aimed at children aged 9 months to 14 years.
  • The study analyzed factors influencing vaccine receipt using statistical methods and found that school enrollment, low household income, and community-level socioeconomic status significantly increased vaccine uptake.
  • The campaign effectively targeted and vaccinated underserved populations, improving access to healthcare among the most vulnerable demographics.

  • The study aims to evaluate the global prevalence of issues related to teething in infants and children aged 0-36 months.
  • The research involved analyzing data from 25 studies, which revealed that approximately 80% of infants experience teething problems, with increased biting and irritability being the most common symptoms.
  • Results indicate that while teething affects a large majority of children, the prevalence of symptoms can vary significantly across different geographical areas.

Article Synopsis
  • Chronic inflammation from pulmonary tuberculosis (TB) affects liver metabolism, leading to metabolic disorders by altering gene expression related to immune signaling and reducing metabolic processes.
  • Analysis showed upregulation of interferon (IFN) signaling genes and downregulation of gluconeogenesis-related genes in TB-infected mice's livers.
  • The study also found a correlation between metabolic changes in humans with TB and the progress of the disease, suggesting that TB-induced inflammation significantly impairs liver function and insulin sensitivity.

Background: To reduce burden of pneumonia, India has introduced Pneumococcal Conjugate vaccine (PCV) in routine immunization programme. The state of West Bengal, India introduced PCV in 2021. Uptake of new vaccines depends a lot on knowledge of caregivers on the disease and vaccine This study aimed to assess the knowledge of caregivers regarding pneumococcal diseases and PCV.

Typbar-TCV®, a typhoid conjugate vaccine (TCV), was prequalified by the World Health Organization in 2017. We evaluated its effectiveness in a mass vaccination program targeting children 9 months to 14 years in Navi Mumbai, India, from September 2018 to July 2020. We compared laboratory-confirmed typhoid cases from six clinical sites with age-matched community controls.

Article Synopsis
  • - The study conducted a systematic review and meta-analysis to assess the awareness and acceptability of preexposure prophylaxis (PrEP) among men who have sex with men (MSM) and transgender persons (TG) in India.
  • - Ten studies from South West India indicated that 18.7% of participants were aware of PrEP, while a significant 79.8% expressed willingness to use it, despite PrEP not being available at the time of the studies.
  • - The findings show a strong demand for PrEP among MSM and TG populations in India, suggesting a need for further research on attitudes towards PrEP across different regions of the country.

  • The Sunderban area of West Bengal has a high rate of thalassemia among its impoverished residents, with limited access to healthcare, prompting a study on transfusion-transmitted infections (TTIs) among thalassemia patients.
  • A total of 359 thalassemia patients, aged 1 to 60, underwent blood tests for HIV, hepatitis B, and hepatitis C, with results analyzed for complications and hospitalization.
  • The study found a high prevalence of HCV (14.21%), followed by HBV (2.51%) and HIV-1 (0.58%), with significant complications like liver disease and growth retardation reported among patients.

Tuberculosis (TB) control efforts are limited by ineffective characterisation of tuberculosis infection (TBI) -a heterogeneous spectrum of pre-clinical infection states, invisible to tools of routine clinical screening, that are associated with variable risk of progression to TB disease. In this prospective study, we use positron emission tomography-CT (PET-CT) as a high-resolution imaging modality to characterise and classify structural and metabolic features observed in 16 asymptomatic household TB contacts with normal chest radiographs. We identify four feature patterns that associate with distinct clinical and microbiological outcomes, supporting potential utility of PET-CT for objective classification of TBI phenotypes.

Background: High proportions of Mycobacterium tuberculosis cells in sputum containing triacylglycerol-rich lipid bodies have been shown to be associated with treatment failure or relapse following antituberculous chemotherapy. Although lipid body determination is a potential biomarker for supporting clinical trial and treatment decisions, factors influencing variability in sputum frequencies of lipid body-positive (%LB) M tuberculosis in patients are unknown. We aimed to test our hypothesis that exposure to host-generated NO and M tuberculosis strains are factors associated with differences in sputum %LB.

Background: In 2016, the Global Polio Eradication Initiative (GPEI) recommended the cessation of using type 2 oral poliovirus vaccine (OPV) and OPV, with countries having to switch from the trivalent to bivalent OPV (bOPV) with the addition of inactivated poliovirus vaccine (IPV) in their routine immunization schedule. The current GPEI strategy 2022-2026 includes a bOPV cessation plan and a switch to IPV alone or a combination of vaccine schedules in the future. The focus of our study was to evaluate the immunogenicity of monovalent OPV type 1 (mOPV1) with IPV and IPV-only schedules.
