Sociocultural and drug-related factors associated with adherence to iron-folic acid supplementation among pregnant women - A mixed-methods study.

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. MATERIALS AND METHODS: The present study was conducted as a mixed-methods study with a sequential exploratory design in a rural setting of the Model Rural Health Research Unit (MRHRU) from October 2020 to May 2021. Ten focus group discussions (FGDs; 8 - antenatal women, 1 - mother/mother-in-law, and 1 - health care worker) were conducted, and framework analysis was done to identify themes followed by a quantitative survey with a semi-structured questionnaire among antenatal women (n = 236). Logistic regression was used to analyze factors associated with adherence. RESULTS: The major themes that emerged from FGDs were the sociocultural factors (gender norms, communal fallacies), lack of awareness, and drug-related factors (unpalatability, misperceptions, and experienced side effects). Around 57% were adherent to IFAT. Side effects experienced on IFAT intake (P = 0.001, OR = 2.33), misconceptions regarding IFAT, like weight gain in IFAT use (P = 0.001, OR = 2.86), a big baby with IFAT use (P = 0.000, OR = 5.93) negatively influenced adherence. CONCLUSIONS: The significant gaps between IFAT coverage and consumption surrounded the unpleasant odor and stench of IFAT, side effects, lack of individualized counseling, and misperceptions regarding IFAT use.

Methodology for the early identification of neurodevelopmental disorders in the primary and preschool children in rural India by applying intervention module developed for teachers.

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. Materials and Methods: Primary and preschool teachers of government and government-aided schools and Anganwadi/preschools in the Model Rural Health Research Unit Tirunelveli field practice area will be assigned into two groups. The training module will be developed and validated using neurodevelopmental screening tool (NDST). Before identifying the students using the NDST, the teachers in Group A will get training using the module. Group B is the control group, in which untrained teachers administer the NDST to the children and then will be trained. Neurologists will assess the same children over 1 year. Results: The effectiveness of teacher training for the early detection of children with NDD will be assessed. Thus, the validity of the screening for NDD by the teachers will be estimated. Conclusion: If successful, the module can be incorporated into the Rashtriya Bal Swasthya Karyakram program of India for the early identification of children with NDD.

Micronutrient Deficiency in Pregnancy: Time to Think Beyond Iron and Folic Acid Supplementation.

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. Materials and Methods: It is a community-based cross-sectional study. The study was carried out among pregnant women registered in Primary Health Center, Kallur, Tirunelveli district, Tamil Nadu, India, using a semi-structured data capture tool. The blood samples were collected following standard procedure. Results: The micronutrient status among 139 pregnant women were selenium <1%, copper <1%, zinc 11.5%, iodine 14.4%, Vitamin B12 41.7%, and ferritin 42.4%. Vitamin B12, zinc, and selenium levels showed a significant difference with reference values among the three trimesters. Iron and folic acid supplementation was followed by 58.7% of pregnant women. Multiple micronutrient deficiency with anemia was found among 54.6%. Conclusion: Anemia and micronutrient deficiency are high among pregnant women in this region. Since iron and folic acid supplementation strategies are already being implemented by the government, it is high time that we extend our health policy beyond that and plan for micronutrient supplementation as well.

Polygenic score for Alzheimer's disease identifies differential atrophy in hippocampal subfield volumes.

Hippocampal subfield atrophy is a prime structural change in the brain, associated with cognitive aging and neurodegenerative diseases such as Alzheimer's disease. Recent developments in genome-wide association studies (GWAS) have identified genetic loci that characterize the risk of hippocampal volume loss based on the processes of normal and abnormal aging. Polygenic risk scores are the genetic proxies mimicking the genetic role of the pre-existing vulnerabilities of the underlying mechanisms influencing these changes. Discriminating the genetic predispositions of hippocampal subfield atrophy between cognitive aging and neurodegenerative diseases will be helpful in understanding the disease etiology. In this study, we evaluated the polygenic risk of Alzheimer's disease (AD PGRS) for hippocampal subfield atrophy in 1,086 individuals (319 cognitively normal (CN), 591 mild cognitively impaired (MCI), and 176 Alzheimer's disease dementia (ADD)). Our results showed a stronger association of AD PGRS effect on the left hemisphere than on the right hemisphere for all the hippocampal subfield volumes in a mixed clinical population (CN+MCI+ADD). The subfields CA1, CA4, hippocampal tail, subiculum, presubiculum, molecular layer, GC-ML-DG, and HATA showed stronger AD PGRS associations with the MCI+ADD group than with the CN group. The subfields CA3, parasubiculum, and fimbria showed moderately higher AD PGRS associations with the MCI+ADD group than with the CN group. Our findings suggest that the eight subfield regions, which were strongly associated with AD PGRS are likely involved in the early stage ADD and a specific focus on the left hemisphere could enhance the early prediction of ADD.

GyrA ser83 and ParC trp106 Mutations in Salmonella enterica Serovar Typhi Isolated from Typhoid Fever Patients in Tertiary Care Hospital.

INTRODUCTION: Typhoid fever is endemic in India and other developing countries, causing major public health problems with high morbidity and mortality. The resistance of Salmonella enterica serovar Typhi (S. Typhi) towards commonly prescribed antimicrobials is increasing in developing countries. However, there have been several reports of the therapeutic failure of fluoroquinolones in patients with Salmonella infection. Resistance to quinolones/ fluoroquinolones commonly arises due to target site mutation. AIM: The present study was planned to analyze mutation in Quinolone Resistance Determining Region (QRDR) of quinolone resistant Salmonella isolates. MATERIALS AND METHODS: A total of 133 S. Typhi isolates (blood (n = 131), stool (n=1) and bone marrow aspirate (n=1)) from tertiary care hospitals in Chennai and Puducherry, were included in this study. Minimum Inhibitory Concentrations (MIC) were carried out according to the Clinical Laboratory Standard Institute (CLSI)guidelines 2014. Mutations in gyrA and parC genes were analyzed by PCR-RFLP (Restriction Fragment Length Polymorphism) method followed by DNA sequencing. RESULTS: Of the 133 S. Typhi, 99.2% were resistant to nalidixic acid and 21% were resistant to ciprofloxacin by MIC method. 94% of isolates showed Ser 83 mutation in gyrA and 21.8% of isolates showed Trp106-Gly mutation in parC. CONCLUSION: Mutations in gyrA and parC genes are highly prevalent among Salmonella species. Irrational use of fluoroquinolones may increase the accumulation of mutations in the DNA gyrase and topoisomerase encoding genes, which lead to the emergence of high level fluoroquinolone-resistant Salmonella strains in future.
