Context: Despite the Weekly Iron folic acid supplementation (WIFS) program, the prevalence of anaemia among adolescent girls remains high. Phase 1 Indian Council of Medical Research (ICMR) task force study conducted in 2016 in Kallur showed that the IFA provision rate for adolescent girls was 72% but the consumption rate was only 15% in the Kallur area. The present study was done to identify the gaps for the difference between provision and consumption rate of weekly IFA tablets among adolescent girls using the WHO conceptual framework in home-based settings.

Background: The National Family Health Survey of India (NFHS-5) revealed a lapse in the advancement of mitigating anemia despite free supplementation of iron-folic acid tablets (IFAT) and improvement in IFAT coverage during pregnancy. The local sociocultural beliefs and community perspective toward IFAT are pivotal in reducing the gap between IFAT coverage and consumption. Hence, we proposed the study to assess adherence to IFAT among rural pregnant women and explore the associated factors.

Introduction: Globally, breast cancer affects 2.5 million people annually. Younger women with advanced-stage cancers had a lower survival rate, but early detection enhanced survival chances by 27 to 47%.

Objective: Neurodevelopmental disorders NDD are neurologic processing problems that interfere with learning in children. Primary and preschool teachers who are essential links in public health reach out to such children do not receive any formal training to identify these disorders. Hence, a primary and preschool level intervention addressing the issue is proposed.

Background: Micronutrients play an important role in influencing pregnancy outcomes. Anemia is common among pregnant women against which iron and folic acid supplementation programs are already in action. The study aimed to estimate the prevalence of anemic and selected micronutrient status among pregnant women.

Background/aim: To understand the biological behaviour, ovarian carcinoma should be approached as a complex tissue composed of tumor cells, ECM proteins, endothelial cells, fibroblasts, inflammatory cells and lymphatics. We aimed to investigate the role of proliferation index of the tumor cells, cell adheshion molecules and lymphangiogenesis in the dissemination of tumor in ovarian surface epithelial carcinomas using suitable antibodies.

Materials And Methods: Fifty-nine cases of ovarian carcinoma were assessed immunohistochemically to quantify the intratumoral and peritumoral LVD, podoplanin expression in stroma, E-cadherin expression and proliferation index of the tumor cells.

Background & Objective: Triple-Negative Breast Carcinoma (TNBC) is characterized by an absence of estrogen receptor, progesterone receptor and HER2 neu expression, with distinct molecular, histological and clinical features, aggressive clinical course and a poor prognosis. The objective was to evaluate the expression of Cytokeratin5/6 (CK 5/6), Epidermal Growth Factor Receptor 1 (EGFR 1), E-cadherin and Androgen receptor in tissue sections of TNBC.

Methods: All modified radical mastectomy samples received negative for the three markers were subjected to further studies with CK5/6, EGFR 1, E- cadherin and Androgen receptor staining.

Background: Autoinflammatory disorders are the group of inherited inflammatory disorders caused due to the genetic defect in the genes that regulates innate immune systems. These have been clinically characterized based on the duration and occurrence of unprovoked fever, skin rash, and patient's ancestry. There are several autoinflammatory disorders that are found to be prevalent in a specific population and whose disease genetic epidemiology within the population has been well understood.

Numerous drugs are being widely prescribed for COVID-19 treatment without any direct evidence for the drug safety/efficacy in patients across diverse ethnic populations. We analyzed whole genomes of 1029 Indian individuals (IndiGen) to understand the extent of drug-gene (pharmacogenetic), drug-drug and drug-drug-gene interactions associated with COVID-19 therapy in the Indian population. We identified 30 clinically significant pharmacogenetic variants and 73 predicted deleterious pharmacogenetic variants.

Article Synopsis
  • Autosomal Dominant Cortical Tremor, Myoclonus and Epilepsy is a non-progressive neurological disorder marked by tremors and is inherited in an autosomal dominant manner with a high penetrance.
  • In South India, a study involving a large cohort revealed the disorder in 48 families, but the specific genetic defect was initially unidentified.
  • The whole-genome analysis of affected and unaffected individuals identified repeat expansions in a specific gene on chromosome 8, making it the largest and most detailed genetic study of this condition in a single ethnic group, the "Nadar" community.

With the advent of next-generation sequencing, large-scale initiatives for mining whole genomes and exomes have been employed to better understand global or population-level genetic architecture. India encompasses more than 17% of the world population with extensive genetic diversity, but is under-represented in the global sequencing datasets. This gave us the impetus to perform and analyze the whole genome sequencing of 1029 healthy Indian individuals under the pilot phase of the 'IndiGen' program.

Phenylhydrazine hydrochloride (PHZ) is a chemical compound. PHZ and its derivatives were used firstly as antipyretics, treatment of blood disorders such as polycythaemia Vera. For many years phenyl hydrazine was used for experimental induction of anaemia in animal models.

Biliary cystadenoma is a rare cystic neoplasms of liver that usually occurs in middle-aged women characterized by multiloculated cysts with internal septae and mural nodules. Unilocular biliary cystadenomas are rare and are difficult to differentiate from other cysts by radiology. Biliary cystadenomas are slow growing benign lesions that are easily resectable with a reported recurrence rate of 90% when the resection is incomplete.

Hemophagocytic lymphohistiocytosis (HLH) is a life threatening florid activation of macrophages of the lymphoreticular system. It is reported to be associated with dengue in children in India and carries a high mortality. Patients present with high fever, worsening blood cell counts, splenomegaly, abnormal liver enzymes with features of liver failure, coagulopathy and neurological complications.
