Authors: Mudgal Varchasvi , Niranjan Vijay , Rastogi Pali , Jain Priyash 
Published: June 2022

Background and Aim:
The coronavirus disease 2019 (COVID-19) is a viral pandemic that has infected millions of people that has caused the loss of human lives on an unprecedented scale. India being the second-most populous country in the world has been severely impacted by COVID-19. India began its vaccination drive on 16th January 2021 with a huge burden of 1.3 billion people to be vaccinated. Various factors play their role to predict the success or failure of a vaccination drive. The study was aimed to assess knowledge, belief, barriers, and acceptance of the COVID-19 vaccine among healthcare workers of a tertiary care centre.

Materials and Methods:
This cross-sectional study was done on healthcare workers (HCW) in February 2021. 120 HCWs participated in the study after providing their consent. Data were collected using a semi-structured proforma which included basic sociodemographic details, a questionnaire about acceptance, knowledge, beliefs, and barriers against the COVID-19 vaccine.

Results:
The mean age of the sample was found to be 36.5 years. Average knowledge, calculated by assessing the mean responses to all the questions pertaining to knowledge, was found to be 78%, while an average of 73.5% had positive beliefs regarding the vaccine for COVID-19. Concern over side effects and doubts over vaccine efficacy turned out to be the greatest barriers contributing to vaccine hesitancy. Acceptance rates of 87.4% were obtained across all the samples.

Conclusion:
Physician recommendation, acceptance by peers or family, and more studies to prove vaccine efficacy was widely acceptable cues to encourage vaccination. The study with its key findings could be a helpful aid in policymaking to boost India's vaccination drive.

Published: June 2022

Background and Aim:
Nurses are the backbone of any health system, providing quality care to the patients in the Coronavirus disease-2019 (COVID-19) pandemic. They are working as frontline warriors in this pandemic and giving their services in such challenging and difficult situations. Since nurses have high rates of exposure they are at risk of getting the SARS CoV-2 infection. The aim of the study is to explore the contributing factors for (COVID-19) infection among nurses working in COVID-2019 units.

Background:
Nurses are the backbone of any health system, providing quality care to the patients in this COVID pandemic. They are working as a frontline warrior in this COVID-19 pandemic and giving their services in such difficult situations. Nurses have direct patient contact which makes them at risk of getting an infection.

Materials and Methods:
A qualitative case series design was carried out using conventional thematic analysis through an inductive approach to explore the factors. Fourteen nurses who have turned COVID-19 positive within 7 days of their last working exposure to COVID units were interviewed using the maximum variation purposive sampling technique. Consolidated Criteria for Reporting Qualitative Research guidelines were used to report the study.

Results:
Nurses reported prolonged exposure to COVID-19 patients; challenges in the patient care environment, biological disequilibrium, and exposure to a non-COVID zone were the major factors contributing factors.

Conclusion:
It is necessary to make policies on regulating the adequate manpower (both number and gender adequacy) in various COVID units, training of every nurse, rotation of COVID duties among various teams, regular health checkups of nurses, and smart monitoring of COVID units.

Published: June 2022

Background:
There is evidence that there is a link seen between the level of health-care services and patient contentment with those treatments. In Nigeria, we carried out a comprehensive study of patient satisfaction with health care.

Aim:
The researchers wanted to see how patient satisfaction with health services was described and analysed, if there was a reference point measure of satisfaction, what issues service users thought were important in providing high-quality care, and where there were areas of dissatisfaction.

Methods:
We looked through the databases: Medical Literature Analysis and Retrieval System Online, Excerpta Medica dataBASE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, African Journals OnLine, CDSR, Database of Abstracts of Reviews of Effects, and Health Technology Assessment. Hand searching was used to supplement the searches. Only papers that were published between 2007 and July 2018 were considered. Information from suitable papers were retrieved and examined by two different researchers after the first title, abstract, and full-text assessment. Studies were assessed using the COSMIN Risk of Bias criteria. Content analysis was employed to identify and analyse common topics.

Results:
The total number of references found was 4509. Following the screening process, 45 studies were selected for data extraction. There was no such thing as a satisfaction reference point. Seven themes were found as being significant to patients. Major areas of dissatisfaction were uncovered.

Conclusions:
A multidimensional concept was used to assess patient satisfaction in Nigerian hospitals. The highlighted topics should be included in the creation of rating scales employed in assessing the quality of services in Nigerian health-care institutions.

Authors: Kwaku Aminatu Ayaba , Gadanya Muktar Ahmad , Tsiga-Ahmed Fatimah Isma'il , Jalo Rabiu Ibrahim , Ibrahim Usman Muhammad , Gajida Auwalu Umar , Iliyasu Zubairu , Abubakar Isa Sadeeq 
Published: June 2022

Background:
Bullying is the most common expression of violence among school children globally. Associated with an array of risk and protective factors, it affects the physical, mental, and social well-being of its victims.

Aims:
We assessed the prevalence, patterns, and correlates of bullying among in-school adolescent boys and girls in Kano Metropolis Kano, Nigeria.

Materials and Methods:
Using a mixed-methods study design, structured questionnaires were administered to 635 adolescent boys and girls across 30 schools. The point of saturation was achieved after 13 focus group discussions (FGDs) were conducted with the adolescents. One FGD each was carried out in 13 of the 30 sampled schools. Logistic regression and thematic analysis were used to analyse the data.

Results:
Adolescents were mainly Hausa/Fulani (n = 522, 86.9%), and the most represented age group was the middle adolescence (n = 299, 47.1%). Bullying was prevalent among 73.0% (n = 230) and 61.3% (n = 196) of the boys and girls, respectively, and this difference was statistically significant (P < 0.01). FGDs revealed that bullying was common, and sanctions against it in some girls' schools could possibly explain a lower prevalence. Boys who played sports (Adjusted odds ratio [aOR] = 0.48, 95% confidence interval [CI] = 0.26–0.90), who had delinquent friends (aOR = 0.60, 95% CI = 0.33–0.99) and girls with a good self-esteem (aOR = 0.39, 95% CI = 0.23–0.64), and who had delinquent friends (P = 0.31, aOR = 0.58, 95% CI = 0.36–0.95) were less likely to be bullied. On the other hand, the factors that increased the likelihood of being bullied were having unsupportive teachers (aOR = 2.88, 95% CI = 1.39–5.40), which increased the likelihood of being bullied. FGDs revealed that bullied adolescents were perceived as weak, unpopular, and had few friends.

Conclusion:
Bullying occurred among a significant majority of the in-school adolescents within the metropolis. More commonly in boys, bullying was verbal, as was social bullying among adolescent girls. Antibullying strategies should target individual behaviour, teachers' attitudes, and building a positive school climate. Teaching adolescents skills on self-awareness, self-management, and relationship management are necessary.

Authors: Nwankwo Bilkisu , Jonah Maranatha , Usman Nafisat Ohunene , Nmadu Awawu Grace 
Published: June 2022

Background:
Family planning programs have historically been focused on women. This has reinforced the misconception that family planning is largely a woman's responsibility, with the man playing a peripheral role. Vasectomies are a safe, effective, permanent, and cost-effective modern method of contraception which has poor global uptake in spite of its many benefits.

Aim:
This study aims to assess the knowledge, perception, and acceptance of vasectomy among male teachers in secondary schools in Chikun Local Government Area of Kaduna State, Nigeria.

Materials and Methods:
A cross-sectional descriptive study was carried out using a pretested interviewer-administered questionnaire. A total of 178 male teachers were selected using a multistage random sampling technique. Data were collected and analyzed using SPSS version 23, and the results were presented using tables. Chi-square test of proportion was used to test for association. Fisher's exact test was used where conditions for Chi-square test were not met. The level of statistical significance was set at P < 0.05.

Results:
The mean age of the respondents was 37 ± 7.4 years. Only a small proportion of teachers (6.7%) had good knowledge on vasectomy. Only 5.6% of the teachers had a positive perception about vasectomy, and majority (92.1%) were unwilling to accept to carry out the procedure. The age of the teachers and number of children they had were found to have a statistically significant association with their acceptance of vasectomy (P = 0.004 and P < 0.0001, respectively).

Conclusion:
Majority of the respondents had poor knowledge and negative perception toward vasectomy with a lot of misconceptions. Acceptance of vasectomy was also poor. Intermittent awareness campaigns on family planning methods should be carried out in the community by the local government health authority, and vasectomy should be discussed in detail to improve awareness and dispel misconceptions.

Authors: Aldrin Yanong Cantila  , Rene C. Espino  , Emma K. Sales  
Published: June 2022

To date there are only nine best rubber clones in the Philippines with little knowledge about its molecular information. Nineteen genomic-based simple sequence repeats' (G-SSRs) good genome coverage had provided enough data in evaluating the Philippine best rubber clones (five PB, three RRIM and one Philippine or Phil derived clones) along with two Phil check clones. G-SSRs derived 72 alleles in all with means N, Ne, Ho, and PIC of 3.789, 2.284, 0.569 and 0.508 per G-SSR, respectively. Nine G-SSRs however detected 16 private alleles. AMOVA also revealed 6.37%, 19.26% and 74.37% molecular variance between groups, between and within clones, respectively, with corresponding FST of 0.064. While genetic proximity had a range of 0.184 to 0.487 with corresponding neighborhood-joining tree suggested no similar clones, three groups (PB, RRIM and Phil groups) had delta K of two based from Bayesian structure analysis. Group 1 had RRIM600, RRIM712 and RRIM901 while group 2 had PB217, PB235, PB260, PB311, PB330, SMRX1, UPLBPlant1 and USM1. G-SSRs are suitable for extracting molecular information and distinct alleles, which can be used as reference to authenticate the best rubber clones in the Philippines. Bayesian structure analysis on the other hand assured better resampling strategy and found admixtures. Furthermore, rubber is highly structured in individual level that indicates these clones should be utilized to broaden genetic variability of the Philippine rubber.

Elaborated studies on Schiff base homo-binuclear Cu(II) and Co(II) complexes, spectral, thermal, P-XRD and biocidal studies
Authors: Rajendran Jayalakshmia  , Rangappan Rajavel  
Published: June 2022

A homo-binuclear Cu(II) and Co(II) complexes were synthesized using a Schiff base ligand derived by condensation of 2,6-diaminopyridine and glyoxal. The reasonable geometry of the Schiff base and its binucleating metal complexes were examined by means of elemental and thermal analyses, molar conductance, 1HNMR, UV–Vis, IR, ESR, P-XRD and mass spectra. The ligand behaved as a polydentate, coordinating through the nitrogen atom of the azomethine group, a nearest nitrogen atom of the pyridine group and the oxygen atom of a glyoxal group. From the spectral studies, a six coordinate environment around the metal dimers was confirmed. The binuclear nature of the metal complexes was assessed from their magnetic susceptibility values. Both of the Schiff base and its metal complexes were also tested for their in vitro antimicrobial activities against some bacterial and fungal strains. Schiff base and the metal complexes were also investigated for its cytotoxic effect against human breast cancer (MCF7) cell lines.

Authors: Iman Maralkhani  , Abolfazl Taherkhani  
Published: June 2022

The purpose of this study is to investigate the thermal buckling analysis of cylindrical shells of carbon nanotubes reinforced composites (CNTRC). In this study, a hybrid laminate composite plate consisting of N layers which are of thickness t is designed. N is the number of layers and the thickness of each functionally graded carbon nanotube reinforced composite (CNTR-FG) layer is h, and three types of the distribution of carbon nanotubes (CNT) are considered for each layer. CNTR-FG are multi-layered plates which have the length "a", width "b", thickness "t", and an arbitrary combination of boundary conditions along the four edges of the layer. The distribution of carbon nanotubes along the thickness of each layer of CNTR-FG is considered to be given. Implementation is done by using Abaqus software. In the investigation of the thermal buckling of cylindrical shells of CNTRC, in three different types of distribution of carbon nanotubes, the behavior of buckling of a cylindrical shell is investigated. In each case, the amount of buckling generated in the shell is calculated and analyzed. The results show that the behaviors of these three types of distributions are close, and the nanotubes with uniform distribution against thermal buckling loads perform better than the other two distributions.
