Clinico-epidemiological presentations and management of Nipah virus infection during the outbreak in Kozhikode district, Kerala state, India 2023.

India experienced its sixth Nipah virus (NiV) outbreak in September 2023 in the Kozhikode district of Kerala state. The NiV is primarily transmitted by spillover events from infected bats followed by human-to-human transmission. The clinical specimens were screened using real-time RT-PCR, and positive specimens were further characterized using next-generation sequencing.

Profile of COVID-19 breakthrough cases and its comparison with unvaccinated COVID-19 cases among healthcare workers in a tertiary care centre in North Kerala.

Background: Healthcare workers (HCWs) were the most vulnerable group during COVID-19 pandemic and had faced many challenges including high rate of breakthrough infections.

Aims: To study the incidence of reported breakthrough infections among HCWs in Government Medical College, Kozhikode and to compare profile of COVID-19 infection between fully vaccinated and unvaccinated COVID-19 positive HCWs.

Settings And Design: The research was conducted as a prospective study for a duration of 78 weeks from 1 of March 2020 through 31 of August 2021 in Government Medical College, Kozhikode.

The Sociodemographic Profile of Community-Dwelling Older Adults With Serious Mental Illness in Kerala - A Cross-Sectional Study.

Background: Older adults with serious mental illness (OASMI) have to manage the twin challenges of old age and mental illness. Understanding their characteristics will help policymakers and researchers plan tailored interventions. The profile of OASMI is not described in any publication from India, and this paper addresses that gap.

Prevalence of anaemia and associated factors among antenatal women in rural Kozhikode, Kerala.

Context: Anemia in pregnancy is a significant public health concern with detrimental aftereffects on maternal and fetal well-being universally, especially in developing countries like India.

Aims: To estimate the prevalence of anemia in pregnant women in rural areas of Kozhikode by hemoglobin estimation and to study the selected factors associated with anemia.

Settings And Design: A cross-sectional study was conducted among 295 antenatal women in all three trimesters residing in six selected panchayats of Kozhikode district from July 2016 to March 2017.

COVID-19 infection among health care workers in a tertiary care teaching hospital in Kerala - India.

Unlabelled: Health care workers are at the frontline for management and containment of COVID-19 infection which has put them at additional risk of the disease. Infection and subsequent quarantine of contacts among HCW may produce considerable strain on the health care system. It is essential that we study the modes by which HCW may get infected in the work environment.

The Research Protocol of SENIOR Project-Psychiatric Services and Support System for Serious Mental Illness in Old Age, Kerala, India.

Background: India has the second-largest population of elderly in the world. Serious mental illness (SMI) is a subset of the mental disorders that result in significant functional impairment and is usually long term. Persons with SMI face several challenges in their old age that are different from the issues faced by younger people with SMI.

Carbapenem-Resistant Gram Negative Bacilli Are Predominantly Multidrug or Pan-Drug Resistant.

Carbapenems, although originally introduced against multidrug-resistant (MDR) Gram negative bacilli (GNB), are now advocated for initial empiric use resulting in increasing carbapenem-resistant (CR) GNB. In this study, we analyzed the frequencies of CR-GNB and compared their resistance patterns against other antibiotics. Overall, 42% (1,014/2,420) of CR-GNB were isolated (range: 29-59%), with similar frequencies among hospitalized and community-acquired infections.

Nipah Virus Infection in Kozhikode, Kerala, South India, in 2018: Epidemiology of an Outbreak of an Emerging Disease.

Background: An outbreak of the rare and highly pathogenic Nipah virus infection occurred in Kozhikode, Kerala, India, during May 2018.

Methodology: Outbreak control activities included laboratory case confirmation and isolation. Contact surveillance was initiated and close contacts were home quarantined for the maximum incubation period of the disease.

Diagnostic delay and associated factors among patients with pulmonary tuberculosis in Kerala.

Introduction: Delay in the diagnosis of tuberculosis (TB) can lead to an increased infectivity period, delayed treatment, and increased severity of the disease. The objective of this study was to estimate the diagnostic delay and factors associated with the delay in diagnosis among the newly diagnosed smear-positive pulmonary TB patients in Kerala, India.

Materials And Methods: A cross-sectional study was conducted among TB patients who were in the intensive phase of directly observed treatment short-course treatment in four randomly selected TB units in a district in Kerala during the years 2012-2013.

Small-Molecule Ice Recrystallization Inhibitors Improve the Post-Thaw Function of Hematopoietic Stem and Progenitor Cells.

The success of hematopoietic stem cell transplantation depends in part on the number and the quality of cells transplanted. Cryoinjuries during freezing and thawing reduce the ability of hematopoietic stem and progenitor cells (HSPCs) to proliferate and differentiate after thawing. Up to 20% of the patients undergoing umbilical cord blood (UCB) transplant experience delayed or failed engraftment, likely because of the inadequate hematopoietic potency of the unit.

Adipogenic Mesenchymal Stromal Cells from Bone Marrow and Their Hematopoietic Supportive Role: Towards Understanding the Permissive Marrow Microenvironment in Acute Myeloid Leukemia.

Purpose: The role of bone marrow-derived mesenchymal stem/stromal cells (MSCs) in creating a permissive microenvironment that supports the emergence and progression of acute myeloid leukemia (AML) is not well established. We investigated the extent to which adipogenic differentiation in normal MSCs alters hematopoietic supportive capacity and we undertook an in-depth comparative study of human bone marrow MSCs derived from newly diagnosed AML patients and healthy donors, including an assessment of adipogenic differentiation capacity.

Findings: MSCs from healthy controls with partial induction of adipogenic differentiation, in comparison to MSCs undergoing partial osteogenic differentiation, expressed increased levels of hematopoietic factors and induced greater proliferation, decreased quiescence and reduced in vitro hematopoietic colony forming capacity of CD34(+) hematopoietic stem and progenitor cells (HSPCs).

Mesenchymal stromal cells from patients with acute myeloid leukemia have altered capacity to expand differentiated hematopoietic progenitors.

The bone marrow microenvironment may be permissive to the emergence and progression of acute myeloid leukemia (AML). Studying interactions between the microenvironment and leukemia cells should provide new insight for therapeutic advances. Mesenchymal stromal cells (MSCs) are central to the maintenance of the hematopoietic niche.
