Comparative analysis of the diversity of trinucleotide repeats in bacterial genomes.

The human gut is the most favorable niche for microbial populations, and few studies have explored the possibilities of horizontal gene transfer between host and pathogen. Trinucleotide repeat (TNR) expansion in humans can cause more than 40 neurodegenerative diseases. Further, TNRs are a type of microsatellite that resides on coding regions can contribute to the synthesis of homopolymeric amino acids. Hence, the present study aims to estimate the occurrence and diversity of TNRs in bacterial genomes available in the NCBI Genome database. Genome-wide analyses revealed that several bacterial genomes contain different types of uninterrupted TNRs. It was found that TNRs are abundant in the genomes of Alcaligenes faecalis, Mycoplasma gallisepticum, Mycoplasma genitalium, Sorangium cellulosum, and Thermus thermophilus. Interestingly, the genome of Bacillus thuringiensis strain YBT-1518 contained 169 uninterrupted ATT repeats. The genome of Leclercia adecarboxylata had 46 uninterrupted CAG repeats, which potentially translate into polyglutamine. In some instances, the TNRs were present in genes that potentially encode essential functions. Similar occurrences in human genes are known to cause genetic disorders. Further analysis of the occurrence of TNRs in bacterial genomes is likely to provide a better understanding of mismatch repair, genetic disorders, host-pathogen interaction, and homopolymeric amino acids.

Malaria infection and associated household level risks in an urban and rural areas of West Bengal.

BACKGROUND OBJECTIVES: Malaria is one of the most critical public health problem globally as well as nationally. Recent times have seen an increase in the importance of the possible effects of environmental and demographic factors on the local transmission of malaria. We conducted a community-level study between urban and rural areas to find out the factors associated with malaria infection. METHODS: A community based observational cross-sectional study was conducted between October 2020 to September 2022 among 330 households from urban area of Chetla, Kolkata and rural areas of Singur district of West Bengal. Households were selected by two stage random sampling method. Study done by face-to-face interview, review of medical records and observation of the households. SPSS software was used for data analysis. Multivariable logistic regression (hierarchical model) done. (p-value equal to or less than 0.05 was taken as significant). RESULTS: The prevalence of malaria infection among participants and household level risks of malaria infection were found 6.1%, 1.8% and 18.8%, 6.7% respectively in the urban and rural areas. Significant predictors of malaria infection were household with ≥5 family members [AOR=2.91{CI (1.19-7.15)}], households not used any mosquito protective measure [AOR=3.71{CI (1.04-13.13)}], presence of mosquito breeding place [AOR=4.93{CI (1.53-15.93)}], absence of effective window screen [AOR=3.19{CI (1.16-8.71)}], absence of separate kitchen [AOR=2.38{CI (1.06-5.34)}], and inadequate lighting condition of house [AOR=4.35{CI (1.78-10.64)}]. INTERPRETATION CONCLUSION: This study provides important insights into the epidemiology of malaria in a high and also low-transmission setting in West Bengal. Intensified efforts to be strengthen towards community mobilization for preventing breeding places for mosquito. Policy should strengthen investment in housing programme that may complement reduction of malaria transmission. Disease reduction effects of Government and local NGOs should be directed towards those areas in order to decrease disease load.

Integrated multiomics analysis of chromosome 19 miRNA cluster in bladder cancer.

With 46 microRNAs (miRNAs) embedded tandemly over a distance of ~100 kb, chromosome 19 microRNA cluster (C19MC) is the largest miRNA cluster in the human genome. The C19MC is transcribed from a long noncoding genomic region and is usually expressed simultaneously at a higher level. Hence, we performed an integrative multiomics data analysis to examine C19MC regulation, expression patterns, and their impact on bladder cancer (BCa). We found that 43 members of C19MC were highly expressed in BCa. However, its co-localization with recurrent copy number variation (CNV) gain was not statistically significant to implicate its upregulation. It has been reported that C19MC expression is regulated by a well-established CpG island situated 17.6 kb upstream of the transcription start site, but we found that CpG probes at this island were hypomethylated, which was not statistically significant in the BCa cohort. In addition, the promoter region of C19MC is strongly regulated by a group of seven transcription factors (NR2F6, SREBF1, TBP, GATA3, GABPB1, ETV4, and ZNF444) and five chromatin modifiers (SMC3, KDMA1, EZH2, RAD21, and CHD7). Interestingly, these 12 genes were found to be overexpressed in BCa patients. Further, C19MC targeted 42 tumor suppressor (TS) genes that were downregulated, of which 15 were significantly correlated with patient survival. Our findings suggest that transcription factors and chromatin modifiers at the promoter region may regulate C19MC overexpression. The upregulated C19MC members, transcription regulators, and TS genes can be further exploited as potential diagnostic and prognostic indicators as well as for therapeutic management of BCa.

Effect of educational intervention on risk factors of cardiovascular diseases among school teachers: a quasi-experimental study in a suburb of Kolkata, West Bengal, India.

OBJECTIVE: This prospective study aimed to evaluate the effects of a health education intervention on cardiovascular disease (CVD) risk factors among school teachers. METHODS: The study, conducted from August 2016 to May 2017, involved teachers from four schools in Baruipur, West Bengal, India. It was a multicentric, quasi-experimental study with an intervention group receiving tailored health education promoting lifestyle modifications, while the control group received no intervention. Baseline and endline assessments included behavioural and biological characteristics related to cardiovascular health and risk assessment. Data were analysed using JAMOVI. RESULTS: The intervention group showed significant improvements in physical activity levels [Cohen's d (Cd): 0.43, p = 0.006] and the consumption of fruits and vegetables (Cd: 1.00, p = < 0.001). Notably, there was a considerable reduction in the consumption of salt (Cd: -0.93, p = 0.039), oil (Cd: -0.98, p = < 0.001), fast food (Cd: -0.99, p = < 0.001), junk food (Cd: -0.99, p = < 0.001), and red meat (Cd: -1.00, p = < 0.001) among participants. However, there were no significant improvements in biological characteristics within the intervention group. In contrast, the control group exhibited no significant changes in behavioural and biological characteristics compared to baseline. The intervention group showed a minor non-significant reduction (3.0%) in their 10-year cardiovascular risk compared to baseline (Cd: -1.00, p = 0.50), while the control group had a negligible non-significant increase (0.7%) in their cardiovascular risk (Cd: 1.00, p = 1.00). CONCLUSION: Health education intervention positively influenced behavioural characteristics, such as physical activity and dietary habits, among school teachers. However, no significant improvements were observed in biological characteristics or cardiovascular risk factors.

CmirC: an integrated database of clustered miRNAs co-localized with copy number variations in cancer.

Genomic rearrangements and copy number variations (CNVs) are the major regulators of clustered microRNAs (miRNAs) expression. Several clustered miRNAs are harbored in and around chromosome fragile sites (CFSs) and cancer-associated genomic hotspots. Aberrant expression of such clusters can lead to oncogenic or tumor suppressor activities. Here, we developed CmirC (Clustered miRNAs co-localized with CNVs), a comprehensive database of clustered miRNAs co-localized with CNV regions. The database consists of 481 clustered miRNAs co-localized with CNVs and their expression patterns in 35 cancer types of the TCGA. The portal also provides information on CFSs, miRNA cluster candidates, genomic coordinates, target gene networks, and gene functionality. The web portal is integrated with advanced tools such as JBrowse, NCBI-BLAST, GeneSCF, visNetwork, and NetworkD3 to help the researchers in data analysis, visualization, and browsing. This portal provides a promising avenue for integrated data analytics and offers additional evidence for the complex regulation of clustered miRNAs in cancer. The web portal is freely accessible at http://slsdb.manipal.edu/cmirclust to explore clinically significant miRNAs.

Research rating: Some technicalities.

From time immemorial, the body of scientific knowledge has grown with incremental additions of research. Metrics-based research evaluation provides crucial information regarding research credibility that would be difficult to understand by means of individual expertise. h-index and its modifications give an approximate quantitative measure of research output. Furthermore, g-index, e-index, h-index and i10-index address various intricacies involving authorship. Altmetrics and Plum X metrics are newer usage metrics that put an additional weightage on the impact on social media, usage, capture and scholarly networking. Indirect evaluation of research can also be obtained from the Journal Impact Factor in which the research is published but with certain limitations. While the scientific community is still waiting for a unique one-stop solution based on a high-quality robust process to exert judgement on research, the Leiden Manifesto comprising ten principles for research assessment can act as a guiding tool for development of a comprehensive evaluation system.

Hazardous practices related to blood borne viral infection transmission among male barbers: A study in a rural area of West Bengal.

BACKGROUND: Barbers are occupationally predisposed to blood borne viral infection (BBVI) such as human immunodeficiency virus, hepatitis B and C. Unhygienic workplaces, improper disinfection and inadequate wound-care can increase the susceptibility of both clients and barbers to BBVI. There is paucity of studies on practices regarding BBVI among barbers, especially in India. OBJECTIVES: To identify the pattern and predictors of practices related to BBVI transmission among male barbers in a rural area of West Bengal. METHODS: A cross-sectional study was conducted from June 2017 to August 2019 in Indas block of Bankura district among 138 male barbers, who were permanent residents and worked for >6 months. Barbers, randomly selected from 10 Gram Panchayats according to probability proportionate to size, were interviewed. Two barbering sessions were observed. Data were analyzed using SPSS version 16 software. Univariate and multiple linear regression was carried out to identify predictors of better practices. P < 0.05 was considered for statistical significance. RESULTS: Dangerous practices such as reuse of blades (8, 5.8%) and face-towel (77, 55.8%), sale/distribution of used blades (77, 55.8%), improper disinfection of sharps (79, 57.2%), reuse of alum without disinfection (129, 93.5%), and improper wound care (71, 51.4%) were observed. Predictors of better practice regarding BBVI were better attitude regarding BBVI (B = 0.172, standard error [SE] = 0.046, P = 0.000) and increased years of schooling (B = 0.054, SE = 0.021, P = 0.012). CONCLUSION: Inimical infection control practices were noticed. They are serving the general people and therefore they should be imbibed with correct BBVI knowledge and must do away with all hazardous practice during their barbering activities.

Evaluation of village health and nutrition day program in a block of Hooghly District, West Bengal: A mixed-methods approach.

BACKGROUND: Village Health and Nutrition Day (VHND) is a community participation program focusing on pregnant women, lactating mothers, children (0-5 years), and adolescent girls. OBJECTIVES: To assess the status of VHND functioning in the rural areas, and to determine the facilitators and barriers of health care service utilization among the beneficiaries. Also, to explore the challenges faced by the front-line workers while conducting the program. METHODS: A cross-sectional descriptive study with a mixed-methods approach was conducted among the beneficiaries and the service providers in twelve selected VHND sessions from March to July 2019 in Singur, Hooghly district, West Bengal. Both quantitative and qualitative methods of research were applied to assess the status of the functioning of 12 VHNDs. RESULTS: Among the beneficiaries who attended the sessions; 28.57% were pregnant women, 16.53% were lactating mothers and 17.44% were under-five children. Nonavailability of line-list of adolescent girls and nonavailability of Vitamin A in oil were major observations. Barriers leading to poor service utilization among beneficiaries were the long-distance of the VHND session site, lack of counseling on proper lifestyle practices, poor and inadequate infrastructure. House visits by the Accredited Social Health Activists regarding the information on VHND sessions found to be an important facilitating factor for beneficiaries. Major challenges identified among the healthcare workers were lack of logistics supply, inadequate workforce, and improper the maintenance of the VHND session site. CONCLUSION: Proper resource mobilization, maintenance and cleanliness of the session sites, appropriate and wholesome counseling can vastly improve the quality of VHND with the concurrent improvement of maternal and child health.

Elder abuse and its predictors: a cross-sectional study in a rural area of West Bengal, eastern part of India.

BACKGROUND: Elder abuse is an important public health problem hidden from public view in spite of its detrimental effect on physical and mental health. In the last three decades, there is responsiveness toward abuse of children and spouses worldwide but even today abuse and neglect of aged people seem to be the matter of least concern. This study aims to reveal the magnitude of elder abuse and its predictors. METHODS: This is a cross-sectional study carried out in a community setting among elderly people (60 years and older) from October 2015 to September 2017 in a rural area of West Bengal, eastern part of India. Elder abuse was elicited by questions adapted from the Actual Abuse Tool. Data were analysed using SPSS (version 16.0). Logistic regression analysis was performed to reveal the factors associated with elder abuse. RESULTS: The study found that 25.6% of the respondents had experienced abuse, psychological abuse being the commonest type. Disability was the most common perceived risk for abuse. Univariate logistic regression showed higher age (70 years and older), female gender, who were Scheduled caste, living in a nuclear family, having more than three children, financially and functionally dependent, who was suffering from depression and multimorbidity had increased odds of being abused. In multivariable logistic regression, people aged above 70 years, living in a nuclear family and dependent for instrumental activities of daily living remained significant predictors of abuse. CONCLUSION: Around one in four of the respondents was abused in a 1 year duration which implies the urgent need for action. Routine screening for elder abuse at ground level and abuse prevention campaigns can be an important measure to alleviate this hidden problem. Also, there is a need to explore culturally specific forms of elder abuse to provide an age-friendly environment.

Metabolic syndrome and its correlates: A cross-sectional study among adults aged 18-49 years in an Urban Area of West Bengal.

BACKGROUND: The prevalence of metabolic syndrome (MetS) is increasing dramatically of late, across all ages irrespective of gender, socioeconomic status, and ethnicity. People with MetS have twice the likelihood of developing and dying from cardiovascular disease and more than seven times the risk of developing diabetes. OBJECTIVES: This study was undertaken to determine the prevalence of MetS among adults who were in their first three decades of adulthood and to find out the risk factors of MetS among them. METHODS: This was a community based cross-sectional study among 388 subjects aged 18-49 years selected by multistage random sampling in an area of Kolkata, India, from November 2016 to October 2018 over 2 years. Data collection was done using a structured questionnaire along with anthropometry, blood pressure measurement, and relevant blood tests. Physical activity was classified by the International Physical Activity Questionnaire Short-Form questionnaire. Data were analyzed using the Statistical Package for the Social Sciences (version 16.0), and descriptive statistics were calculated as frequency and percentage. Logistic regression was done to determine the strength of association between MetS and different risk factors. RESULTS: The prevalence of MetS was 44.6% (35.4% in males and 55.6% in females), and female gender, poor economic status, sedentary lifestyle, poor diet, and addiction of tobacco were found to be the risk factors of MetS in the final model using multivariable logistic regression. CONCLUSION: This research revealed the high prevalence of MetS in the community. The effective primordial and primary level of prevention along with prevailing secondary or tertiary level of prevention should have been employed to curtail the epidemic of MetS.

Bone health and its association with vitamin D and other covariates: A community-based study among women in a rural area of West Bengal.

BACKGROUND: Low bone mineral density (BMD) is implicated in the pathogenesis of osteoporosis and osteopenia, and primarily manifest as fragile bones. This is a rapidly emerging global health problem with increasing prevalence in India. OBJECTIVES: The objective of this was to assess the status of bone health and find its determinants among women aged 40 years and above in a rural population of West Bengal. METHODS: A community-based cross-sectional study was conducted from May 2017 to April 2018 among 260 women aged 40 years and above residing in the selected villages of Singur through multistage random sampling. Each respondent was interviewed using a structured schedule. Serum Vitamin D and calcium levels were investigated. BMD was assessed through calcaneal quantitative ultrasound. Osteoporosis was diagnosed among those with T-score ≤-2.5, while those with 25(OH) Vitamin D <30 ng/ml were classified to have Vitamin D insufficiency (VDI). Individuals with BMD T-score <-1 were considered to have low BMD. Inferential statistics were employed to find the associates of poor bone health. RESULTS: Out of 260 participants, 34 (13.1%) were screened positive for osteoporosis and 77.7% had low BMD. Approximately 75% had VDI. On multivariable analysis, VDI (adjusted odds ratio [95% confidence interval] = 4.13 [2.12, 8.37]) was a significant predictor of low BMD after adjustment for poor education, decreasing diet score, menopause, presence of comorbidity, underweight, and overweight explaining 43.6% of the variance. CONCLUSION: Serum Vitamin D levels are implicated to play a crucial role in bone metabolism; however, its effect on the body in accordance with other important hormones should be explored.

Genome-based taxonomic classification.

Bacterial populations are routinely characterized based on microscopic examination, colony formation, and biochemical tests. However, in the recent past, bacterial identification, classification, and nomenclature have been strongly influenced by genome sequence information. Advances in bioinformatics and growth in genome databases has placed genome-based metadata analysis in the hands of researchers who will require taxonomic experience to resolve intricacies. To achieve this, different tools are now available to quantitatively measure genome relatedness within members of the same species, and genome-wide average nucleotide identity (gANI) is one such reliable tool to measure genome similarity. A genome assembly with a gANI score of <95% at the intraspecies level is generally considered indicative of a separate species. In this study, we have analysed 300 whole-genome sequences belonging to 26 different bacterial species available in the NCBI Genome database and calculated their similarity at the intraspecies level based on gANI score. At the intraspecies level, nine bacterial species showed less than 90% gANI and more than 10% of unaligned regions. We suggest the appropriate use of available bioinformatics resources after genome assembly to arrive at the proper bacterial identification, classification, and nomenclature to avoid erroneous species assignments and disparity due to diversity at the intraspecies level.

Community perception and risk reduction practices toward malaria and dengue: A mixed-method study in slums of Chetla, Kolkata.

BACKGROUND: Globally, vector-borne diseases account for 17% of infectious disease burden. In India, despite accelerated efforts, both malaria and dengue are major public health concern. Understanding local community perspectives is essential to strengthen ongoing program activities. OBJECTIVES: The study aimed to assess the community perceptions and risk reduction practices toward prevention and control of malaria and dengue at slums of Chetla in South Kolkata and to explore the perspectives of relevant local stakeholders in this regard. METHODS: This cross-sectional study with mixed-method design was conducted from June to September 2018. Quantitative data were collected in 288 sampled households through face-to-face interview of respondents and environmental checklist, whereas, qualitative exploration was done with five key informant interviews. Quantitative data were analyzed using SPSS version 16 Software. Qualitative data were analyzed thematically using "cut and sort" processing technique. RESULTS: In household survey, majority had unsatisfactory knowledge (68.4%), attitude (64.2%), and practices (62.8%) regarding diseases prevention/control, which was further substantiated by qualitative findings. The use of electric fans (79.5%), mosquito repellents (53.8%) were predominant practices; however, only a few used bed nets regularly (26.0%). Reportedly, "heat" and "poor ventilation" were key reasons behind reluctance to use bed nets. Multivariable regression analysis revealed that increasing age, proximity to a nearby canal, and unsatisfactory knowledge significantly predicted unfavorable attitude, whereas, respondents' gender and unfavorable attitude significantly predicted poor practices. CONCLUSIONS: Intensified social behavior change communication with active community participation is the need of the hour to prevent malaria and dengue occurrence and future outbreaks.

Private sector involvement envisaged in the National Strategic Plan for Tuberculosis Elimination 2017-2025: Can Tuberculosis Health Action Learning Initiative model act as a road map?

Tuberculosis (TB), one of the oldest diseases known to mankind has become a notifiable disease. Public private mixes guidelines for TB programme managers had already been published by Central TB Division in the Ministry of Health and Family Welfare. One of the tremendous challenges that impede private sector involvement in TB care is delayed diagnosis, treatment of variable quality, surveillance, adherence monitoring, contact investigation, and outcome recording. The present article has addressed the involvement of the private sector with special emphasis on Tuberculosis Health Action Learning Initiative (THALI) model. The key elements of THALI being: (1) Identifying and scaling up of innovative approaches to improve the quality of private sector diagnosis, referral, and treatment of TB, (2) Strengthening the utilization of TB resources of the respective municipalities, (3) Testing of upcoming technological innovations, and (4) Improving data for evidence-based decision making. Nevertheless, sustainable parallel implementation framework adopting the strategies of THALI Model, along with prior Geographic Information System mapping of private health facilities e.g. hospitals/nursing homes, private providers, diagnostic centres, pharmacies etc. should be in place so as to correctly implement the slogan - "Unite to end TB: Leave no one behind".

In silico characterization of functional single nucleotide polymorphisms of folate pathway genes.

Folate metabolism genes are pivotal to critical biological processes and are related to several conditions, including developmental, cognitive, and cardiovascular anomalies. A systematic catalog of genetic polymorphisms in protein coding regions, regulatory transcription factor binding sites, and miRNA binding sites associated with folate pathway genes may contribute to personalized medicine. We performed a comprehensive computational survey of single nucleotide polymorphisms (SNPs) of folate pathway genes to highlight functional polymorphisms in the coding region, transcription factor binding sites, and miRNAs binding sites. Folate pathway genes were searched through PubMed and Kyoto Encyclopedia of Genes and Genomes pathway databases. SNPs were identified and characterized using the University of California, Santa Cruz genome browser and SNPnexus tool. Functional characterization of nonsynonymous SNPs (nsSNPS) was performed using bioinformatics tools, and common deleterious nsSNPs were identified. We identified 48 genes of folate pathway containing 287 SNPs in the coding regions. Out of these SNPs, rs5742905, rs45511401, and rs1801133 were predicted to be deleterious through four different bioinformatics tools. Three-dimensional structures of two proteins with and without deleterious nsSNPs were predicted by SWISSPDB viewer and SuperPose. Besides, a total of 237 SNPs was identified in transcription factor binding sites using the Genomatix software suite and six miRNA target site SNPs using miRNASNP. This systematic and extensive in silico analysis of functional SNPs of folate pathway may provide a foundation for future targeted mechanistic, structure-function, and genetic epidemiological studies.

War against tobacco: Where do we stand?

India has launched war against tobacco epidemic for the past few decades but with partial success; hence, challenges are still there which need to be identified and addressed for winning the battle. Targeted approach directed at motivating smoking cessation of female smokers, frequent changing of pictorial warnings depicting variety of health consequences in cigarette packets and devoid of logos and colors in conjunction with plain packaging, and display of toll-free number for quitting are expected to dissuade tobacco consumers to quit and save themselves from the devastating health, social, environmental, and economic consequences of tobacco consumption. Online reporting system for violating legal enforcements can also be implemented easily. Moreover, guidance from success stories of countries/states who have achieved smoke-free status along with concerted efforts such as innovative anti-tobacco campaigns, involvement of religious leaders in anti-tobacco propaganda, strict legislations, and overall strong political commitment would further aid in winning the war.

Exposure to indoor air pollution and its perceived impact on health of women and their children: A household survey in a slum of Kolkata, India.

BACKGROUND: One's house is believed to be the safest and the healthiest place to live in. Indoor air pollution (IAP) means the presence of unwanted substances in the indoor air at concentration toxic to health. OBJECTIVE: The objective of this study is to study the presence of IAP, its associated factors and impact on health of women residing in an urban slum of Kolkata, West Bengal, India. METHODS: It was a cross-sectional study done from January 2017 to March 2017 among 120 households of a slum. Data were collected using a pre-designed pre-tested schedule from the homemaker of the households. All analyses were conducted with R: A Language and Environment for Statistical Computing. RESULTS: About 60% households used kerosene as cooking fuel predominantly. Smoke from the neighbouring houses troubled 57.5% respondents. More than 60% houses were overcrowded and more than 70% houses were poorly ventilated. IAP-related symptoms such as irritation in the eye, suffocation, dry cough significantly correlated with the presence of IAP sources and its contributory factors. Of 120, 78 (65%) perceived the presence of IAP in their houses. Lower per capita income (PCI), ground floor, and joint family were found to have higher odds of sources of IAP. Younger age, lower PCI, and ground floor were found to be strongly associated with higher contributory factors of IAP. CONCLUSION: The present study found that the majority of the households were exposed to IAP due to kerosene, neighborhood smoke while overcrowding and ill-ventilation accentuated it. Effective intervention with intersectoral coordination is the need of the hour.

Sun exposure and Vitamin D in rural India: A cross-sectional study.

BACKGROUND: Vitamin D deficiency/Vitamin D Insufficiency (VDI) is now recognized as a pandemic. Cutaneous exposure to ultraviolet-B causes photolysis of epidermal 7-dehydrocholesterol, converting it to pre-Vitamin D3 (precholecalciferol), which then undergoes isomerization to form the stable hormone Vitamin D3. OBJECTIVES: The objectives of the study is to determine the status of Vitamin D level among the adults residing in a rural area of West Bengal and to find out the optimal cutoff of the sun exposure for Vitamin D sufficiency. METHODS: This study was a rural community based cross-sectional study. It was done from May 2016 to April 2017 among 197 adults residing in a rural block of West Bengal. Data were collected by interviewing the respondents with the help of a structured pre-tested pre-designed schedule. After interviewing, every individual was examined for height and weight and blood was collected for serum Vitamin 25-(OH) D. Receiver Operating Characteristic (ROC) curves were utilized to find out optimum cut-off for sun exposure using Youden's index. Binary logistic regression was performed to find out the associates of high sun exposure. All analysis was done using R. RESULTS: Overall VDI was found in 133 (67.5%). Among them, 102 (51.8%) were female. On ROC curve for veritable sun exposure for Vitamin D sufficiency, area under curve was 0.7841 which signifies veritable sun exposure as a good screening tool. CONCLUSION: Proper information, education, and communication material regarding various aspects of sun exposure and Vitamin D should be prepared with due consultation of field experts and disseminated to increase awareness among the community.

Research submission: Some technicalities and vital links.

Publishing allows the author to share with the world his original findings, reasoning, important breakthroughs and it also creates the avenue for mandates of promotion and career upliftment. In an endeavour to publish an article, the first vital technicality that the authors face is selection of an appropriate journal. There has been steady increase in the number of predatory publishers and journals. Knowledge of the different publication models, websites to check valid open access journals and reliance on certain reputable publishing houses may actually guide the authors in selecting legitimate journals. Open Researcher and Contributor ID (ORCID ID) or Researcher ID is required during submission of articles. ResearchGate, Mendeley or Scholar Universe are useful sites to collaborate and disseminate research publication in an effective manner. Search Engine Optimization (SEO) is another vital technicality that needs to be adopted by the authors before submission of the research work for publication to ensure higher visibility of the published research article in the academic community and increase citations. Thorough understanding of the publication process, following simple technicalities of manuscript submission and establishing vital links in the post publication phase is some of the useful guidelines for shaping up the success story of the research.

Mobile phones: time to rethink and limit usage.

Radiofrequency waves generated from mobile phones cause potential public health problems. Short-term effects like changes in sleep, heart rate, and blood pressure, and long-term effects like carcinoma are well documented. The Government of India's efforts in laying down regulations regarding the safety limits, manufacture, marketing, and mobile use are still in nascent stage. The need for stringent enforcement of laws for prevention of phone usage while driving and guidelines of medical regulatory bodies regarding rules and regulations of phone usage while at class or attending patients is of utmost importance. This should be supplemented by mass media to raise awareness among people regarding the possible health effects of radiofrequency emissions from mobile phones and the guidelines to minimize its exposure. It is the need of the hour to teach young people to be structured, to know when to have the cell phone on, and to avoid becoming the slave of technology instead of its mastery.
