A Pilot Study on the Knowledge, Attitude, and Practice of Mothers About Their Children's Vaccination in a Medical Institute in Jharkhand, India.

Introduction Immunisation is one of the key public health instruments to combat childhood morbidity and mortality. However, the lack of mothers' knowledge and motivation to vaccinate their children has affected vaccination programs and vaccination coverage rate in the state of Jharkhand. Therefore, addressing this knowledge gap, our study aims to evaluate the extent of mothers' understanding of the effects and aspects of vaccination for their children. Materials and method This is a cross-sectional study conducted at the paediatric vaccination clinic of Rajendra Institute of Medical Sciences (RIMS), Ranchi between October 2022 and September 2023. The sample population included 200 mothers as participants (18 years and above). The survey was done with a self-administered questionnaire of questions about socio-demographic factors, mothers' knowledge, and mothers' practices, and answers were consolidated in the form of a table. Results The majority of participants in this study were below 25 years of age and were literate. The missed vaccination percentage was also significantly higher among illiterates, mothers below 30 years of age, and unemployed ones. Among the respondents, 73.3% of illiterate mothers, 56% of those below 30 years of age, and 64% of unemployed mothers missed their children's vaccination schedule. Among the mothers, 75% did not know the names of vaccine-preventable diseases. Of the respondents, 50% believed intercurrent illnesses like fever and the common cold to be side effects and contraindications of vaccines. Among the mothers, 65% never posed any questions to the paediatrician. Of the mothers, 97% safely kept the vaccination card and 82% relied on government or public health centres for vaccination purposes. Conclusion The majority of our population was in favour of vaccinating their children but there existed a huge lacuna in their knowledge about vaccination. This study concludes that firmer measures have to be exercised to bridge this knowledge gap. Only this can improve the vaccination coverage rate.

Physical and mental health among older parents: Does offspring migration and living arrangement matter? Findings from Longitudinal Aging Survey in India (2017-18).

The migration of adult children can have beneficial and adverse effects on the health outcomes of elderly parents left behind. This study examines the effects of adult children's migration on self-rated health and depression among older parents using Longitudinal Ageing Study in India (LASI) 2017-18 with 19,401 individuals aged 60 years or older. Binary logistic regression models were performed to determine the association of self-rated health and depression with adult-child migration status while adjusting for living arrangements and socioeconomic factors. Results show that 36 percent of older parents have at least one migrant child, and 35 percent are empty nesters. Older adults living with their children experience positive impacts on their physical and mental health. Our study reveals that empty-nested elderly have a higher prevalence of poor self-rated health and depression. Irrespective of migrant children, the availability of children in the household matters most regarding parents' health care, as our study suggests no significant difference in physical and mental health among left-behind and non-left-behind older parents. This study aims to draw policymakers' attention to the impact of adult children or youth migration on older parents' physical and mental health. To address this issue, policies should prioritize raising awareness among migrant children of older adults about the importance of maintaining frequent contact and visiting their aging parents.

Nanoclusters and nanoalloys of group 13 elements (B, Al, and Ga): benchmarking of methods and analysis of their structures and energies.

We investigated the structural and energetic properties of nanoclusters and nanoalloys composed of group 13 elements (B, Al, and Ga) up to a cluster size of 12. We conducted a comprehensive benchmark analysis of density functional and post-Hartree-Fock methods to identify efficient and accurate approaches for studying these systems using our benchmark dataset (BAlGa16) consisting of sixteen dimers and trimers. We compared different density functionals and post-Hartree-Fock methods using bond length and binding energy as parameters. B2PLYP closely follows CCSD(T) for geometry optimization, while REVPBE, BPBE, and PBE show cost-accuracy balanced performances. MRACPF was used as the reference for benchmarking energies, with NEVPT2 being the most accurate method, followed by CCSD(T) and DLPNO-CCSD(T). M06 and range-separated hybrid functionals perform well. Based on a cost-accuracy analysis, we recommend M06/def2-SVP as the preferred method. Additionally, we explored the structural evolution of pure, binary, and ternary clusters of group 13 elements up to 12 atoms, uncovering global and local minima. Ga clusters exhibited more rectangular faces compared to the predominantly trigonal faces of B and Al clusters. Binary clusters showed B in center positions, while Ga preferred outer positions, confirming the higher cohesion of B. The most favorable size of binary clusters (12) exhibited similar compositions of Al and Ga atoms. Compositions with 16.67-40% B, 16.67-60% Al, and 20-50% Ga were estimated to have negative mixing energies, indicating their relative stability.

Planar pentacoordinate carbon in [XC7H2]2+ (X = Be and Mg) and its derivatives.

The planar pentacoordinate carbon (ppC) atom is theoretically established here in [XC7H2]2+ and [XSi2C5H2]2+, where X = Be and Mg, using density functional theory. Inclusion compounds with alkali and alkaline earth metal ions are identified with the monomer units of tricyclic C7H2 and Si2C5H2 isomers with a planar tetracoordinate carbon (ptC) atom. While all alkali and some alkaline earth metals (Ca2+, Sr2+, and Ba2+) stabilize the ptC isomer in both cases, Be2+ and Mg2+ ions form a bond directly with the ptC atom, thus making it a ppC atom. The theoretical binding energies computed at the PBE0-D3/def2-TZVP level of theory are ∼-9.68, -10.42, -5.85, and -5.47 eV for [BeC7H2]2+, [BeSi2C5H2]2+, [MgC7H2]2+, and [MgSi2C5H2]2+, respectively.

COVID-19 vaccine hesitancy among health care worker-parents (HCWP) in Puducherry, India and its implications on their children: A cross sectional descriptive study.

BACKGROUND: Vaccine hesitancy affects immunization programs worldwide and can impact vaccine coverage and fight against Coronavirus disease 2019 (COVID-19) too. OBJECTIVES: Primary objectives: To find out the magnitude of COVID-19 vaccine hesitancy among the Health Care Worker Parents (HCWPs), the reasons for vaccine hesitancy, and their perceptions regarding COVID-19 vaccination of their children. SECONDARY OBJECTIVE: To analyze the clinic-socio-demographic correlates of COVID-19 vaccine hesitancy among HCWPs. METHODS: This was a cross sectional descriptive study. Health care workers who are parents were invited to participate in the study. Details about COVID vaccination status, COVID-19 illness of HCWPS and family members and its outcomes , reasons for not getting vaccinated, willingness to vaccinate their children, reasons for not willing to vaccinate their children, their responses to vaccine hesitancy survey (VHS) questionnaire and Modified Oxford COVID-19 vaccine hesitancy scale (MOVHS) were collected and analyzed using descriptive statistics. RESULTS: A total of 269 HCWPs participated in the study. Of the HCWPs, 97% had completed their COVID-19 vaccination schedule. Majority stated that they would vaccinate their children when it is available. Although majority of the responses were positive or towards agreement, there were some striking variations in the responses among some sections of HCWPs. Positive responses to the questionnaire were associated with higher self-vaccination and a decision to vaccinate their children. CONCLUSION: Vaccine hesitancy was less common among HCWPs in our study. A section of the HCWPs might be disproportionately more hesitant than others. Majority were in favor of vaccinating their children.
