Background/aim: The majority of traumatic dental injuries (TDI) in childhood and adolescence occur in schools. Since school teachers are often the first responders, their knowledge about the emergency management of TDI needs to be adequate. The aim of this systematic review was to assess and analyse the global status of this knowledge as reported in previous studies and to provide recommendations for future research. Methods: The protocol was designed as per PRISMA guidelines and registered in PROSPERO. A broad-based search using text-words and MeSH terms was performed in established databases as per a predefined strategy. Cohort-studies, crosssectional, case-control studies and randomized/non-randomized trials without any distinction of language and year of publication were included while those without details of sampling strategy, validity and reliability were excluded. Data extraction was performed, risk of bias assessment was done by the Joanna-Briggs-Institute's critical appraisal checklist and meta-analysis was performed for four question stems using a random effects model. Results: Twenty-three studies were included for qualitative analysis. Most of the studies had been conducted in Asia from 2009 to 2019. Ten studies used case-based questionnaires, mostly adapted from previous studies. Moderate to high risk of bias was observed in 14 studies. Less than 50% of teachers had witnessed a TDI in 8 studies and >75% desired to know more about TDI management in most studies. Less than 50% of teachers in 5 out of 6 studies knew about immediate replantation of avulsed permanent teeth, <25% knew about storage of an avulsed tooth in 16 studies and <50% knew about cleaning of a dirty avulsed tooth in 8 studies. Meta-analysis revealed I 2 values of >95% with 17% of teachers having previous dental-trauma firstaid training and 38% knowing about replantation within 30 minutes. Conclusion: The awareness level in several areas of the world is unknown. Studies lacked well-designed questionnaires and teachers exhibited low self-belief and knowledge level in the majority of studies. | 569 TEWARI ET Al.

BackgroundSocio-economic inequity leads to health inequity. Inequity is closely intertwined with internal migration. This study was planned with the objective of documenting the maternal health care utilization among women labourers working in brick kilns situated in an area of Haryana, north India.MethodsA community based mixed method study was done in select brick kilns of Faridabad district in north India. A mixed method study was done to assess maternal health care utilization in a sample of 500 women in the reproductive age group. Focus group discussions were also carried out. Descriptive analysis was done. Qualitative data was analysed using the thematic framework approach.ResultsThe mean age of the women was 30 (SD 0.3) years. Mean number of pregnancies per woman was 3.1 (SD 1.7). Only 22.9% ever had institutional delivery. About one third of women had ever received cash benefit under Janani SurakshaYojana (JSY) or had ever used free ambulance services. Seven major themes emerged from the qualitative analysis. Important themes include-Gaps in knowledge regarding local health system; Sub-standard private health care delivered at brick kilns prevent migrants from accessing the basic public health services; Misconceptions and mistrust about public health system influenced maternal health care utilization; Barriers to avail universal health coverage: location of brick kilns, time, apathy of public health system, partial health insurance cover.ConclusionsA typical migrant woman labourer in the brick kiln was an illiterate, had migrated from poor states, belonged to a socially disadvantaged community and worked long hours, and had been doing so for many years. This study has identified migrant women working in brick kilns as a vulnerable population subgroup in terms of maternal health utilization. To achieve universal health care it is important to understand the needs of all population subgroups and make concerted efforts at the health system level.

ObjectivesTo update the estimation of the adult HIV prevalence and number of people living with HIV (PLHIV) in India for the year 2008−2009 with the combination of improved data and methods.DesignBased on HIV sentinel surveillance (HSS) data and a set of epidemiological assumptions, estimates of HIV prevalence and burden in India have been derived.SettingHSS sites spread over all the States of India.ParticipantsSecondary data from HSS sites which include attendees of antenatal clinics and sites under targeted interventions of high-risk groups, namely, female sex workers (FSW), intravenous drug users (IDU) and men having sex with men (MSM).Primary and secondary outcome measuresEstimates of adult HIV prevalence and PLHIV in India and its states.ResultsThe adult HIV prevalence in India has declined to an estimated 0.31% (0.25–0.39%) in 2009 against 0.36% (0.29–0.45%) in 2006. Among the high prevalence states, the HIV prevalence has declined in Tamil Nadu to 0.33% in 2009 and other states show either a plateau or a slightly declining trend over the time period 2006–2009. There are states in the low prevalence states where the adult HIV prevalence has risen over the last 4 years. The estimated number of PLHIV in India is 2.4 million (1.93–3.04 million) in 2009. Of which, 39% are women, children under 15 years of age account for 4.4% of all infections, while people aged 15–49 years account for 82.4% of all infections.ConclusionsThe estimated adult prevalence has declined in few states, a plateau or a slightly declining trend over the time. In future, efforts may be made to examine the implications of the emerging trend of the HIV prevalence on the recent infections in the study population.

Background Dental professionals are the primary care providers for traumatic dental injuries (TDI). The dental traumatology literature has a number of studies evaluating the knowledge of dental professionals from different parts of the world but its global status is unknown. Hence, the aim of this systematic review was to assess the global status of knowledge for the prevention and emergency management of TDI in dental professionals and to provide recommendations for future research. Materials and Methods The protocol was designed as per the PRISMA guidelines and registered in PROSPERO (CRD42020192381). A broad‐based search using text words and MeSH terms was performed in established databases as per a pre‐defined strategy without any distinction of language and year of publication. Studies without details of the questionnaire, knowledge score, validity and reliability were excluded. Data extraction was performed, risk of bias assessment was done using the Joanna Briggs Institute's critical appraisal tool, and a meta‐analysis was performed. Results Sixteen studies, which had been published between 2008 and 2020, were included for qualitative synthesis. Most of them were cross‐sectional, used convenience sampling and evaluated knowledge for avulsion. Previous dental trauma training was undertaken by <50% of the participants of five studies, <50% knew about the correct approach in management of complicated crown fractures in three studies and ≤60% in four studies knew the critical time for replantation. There was insufficient level of knowledge in >50% of the included studies. High risk of bias was found in three studies. Conclusion The knowledge level in several areas of the world was unknown. The studies lacked uniformity in methods and well‐designed questionnaires and they revealed insufficient levels of knowledge among dental professionals.

Background Despite the well-known short-term and long-term ill effects of elevated blood pressure in children and adolescents, pooled data on its burden among Indian adolescents have not yet been synthesized. Objectives We did a systematic review with meta-analysis to calculate the pooled prevalence of hypertension among adolescents (10-19 years) in India. Methods We searched PubMed, Embase, Cochrane library, Google Scholar and IndMed, and included cross-sectional studies reporting data on hypertension prevalence among 10 to19 years old and published in English language from their inception till 1 st March 2020. Modified New castle Ottawa scale was used to assess risk of bias based on research design, recruitment strategy, response rate and reliability of outcome determination. A random effects model was used to estimate pooled prevalence, and heterogeneity was assessed using Cochrane's Q statistic test of heterogeneity and I 2 statistic. To explore the heterogeneity, we did a meta-regression, and subgroup analyses based on region, study setting and number of blood pressure readings. Results Out of 25 studies (pooled sample of 27,682 participants) six studies were of high, eighteen of moderate, and one was of low quality. The prevalence of hypertension across studies ranged from 2% to 20.5%, with a pooled estimate of 7.6% (95% CI: 6.1 to 9.1%), I 2 = 96.6% (pvalue <0.001). Subgroup analysis restricted only to the western India demonstrated a
