Challenges in screening for sickle cell disease among newborns from the tribal region of Palghar, Maharashtra during the COVID-19 pandemic.

BACKGROUND OBJECTIVES: Despite several adversities imposed by the COVID-19 pandemic, it was crucial to sustain research having public health relevance such as investigations around sickle cell disease (SCD). Against this background, an ongoing ICMR-multicentric study for newborn screening of SCD in the tribal population at Model Rural Health Research Unit (MRHRU-Dahanu) in Palghar District, Maharashtra constituted the current study setting. This was a descriptive study wherein, certain measures were undertaken and strategies were developed in view of the challenges in newborn screening for SCD due to the COVID-19 pandemic during December 2019-September 2021 at Sub District Hospital, MRHRU-Dahanu. METHODS: During the onset of the pandemic, (December 2019-March 2020), the follow up was possible in 26.7 per cent (20/75) of the newborns. Subsequently, challenges such as travel restrictions, fear of COVID-19, shortage of staff were experienced with respect to enrolment and follow up visits. RESULTS: After implementing certain pragmatic strategies (ASHA involvement, usage of virtual platform and flexible visits), follow up rate increased to 47.5 per cent (66/139) between July 2020-April 2021 (post first lockdown) and to 66 per cent (65/98) during the second wave (May 2021-August 2021). INTERPRETATION CONCLUSIONS: The study emphasizes the importance of network building, use of virtual platform and engaging health workers in tribal settings. Such pragmatic approaches have the potential to pave a path for further implementation research involving specific interventions to improve health outcomes in tribal settings.

Enablers & challenges of tribal women & health system for implementation of screening of non-communicable diseases & common cancers: A mixed-methods study in Palghar district of Maharashtra, India.

Background & objectives: Non-communicable diseases (NCDs) and cancers of breast, oral cavity and cervix contribute to around 5.87 million (60%) deaths in India. Despite this, there is limited evidence on preparedness of the tribal health system in mitigating these conditions. This mixed-methods study aimed at identifying enablers and challenges using a multistakeholder approach for the screening of NCDs and common cancers in a tribal block of Maharashtra, India. Methods: This study was conducted in a tribal community of Dahanu taluka in Palghar district of Maharashtra. A total of nine focus group discussions (FGDs) among tribal women and accredited social health activists (ASHAs), 13 key informant interviews (KIIs) among auxiliary nurse midwives (ANMs) and community health officers (CHO) and facility surveys of five public health facilities were conducted. The FGDs and KIIs were conducted using guides, recorded digitally, transcribed, analyzed and triangulated to identify emerging themes. Results: The tribal women had limited knowledge about NCDs and common cancers. Paucity of health facilities, out-of-pocket expenditure, misconceptions, belief on traditional healers and inability to prioritize health were identified as major challenges. The ASHAs were recognized as a key connecting link between health system and community while provision of culturally appropriate IEC materials and adequate training were recognized as critical enablers by healthcare providers in implementing screening for NCDs and common cancers. Interpretation & conclusions: The study recommends incorporating socioculturally relevant strategies in the tribal population and strengthening health facilities in terms of infrastructure and training with involvement of ASHAs for successful implementation of the National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS) through health and wellness centres.

Laboratory diagnosis and epidemiological features of leptospirosis cases in a tribal region of Western Maharashtra, India: A retrospective study.

PURPOSE: Palghar district, located in the coastal region of the Konkan division of Maharashtra, has a predominantly tribal population. Leptospirosis is a major neglected public health problem and is highly underreported in Palghar district. The study aimed to evaluate the seropositivity of Leptospira infection and its associated epidemiological factors in tribal areas of the Palghar district of Maharashtra. METHODS: The present retrospective study included 94 samples of patients clinically suspected of leptospirosis during a period of one year (2021-2022) tested at Model Rural Health Research Unit (MRHRU) Dahanu. The serum sample testing was done for the presence of specific Leptospira IgM antibodies using the Panbio™ Leptospira IgM ELISA kit. Leptospirosis seropositivity was correlated with various epidemiological risk factors. RESULTS: A total of 12 samples of patients tested positive for specific IgM antibodies by ELISA method, indicating an overall positivity of 12.8%. Among those who tested positive, fever (83.3%), headache (58.3%), myalgia (50%), redness of the eyes (50%), and calf tenderness (16.7%) were the common symptoms observed. Subjects with redness of the eyes were significantly associated with leptospirosis (p = 0.018). The highest positivity (50%) was reported from the Ganjad area of Dahanu taluka. Farmers and animal handlers were most affected by leptospirosis. CONCLUSION: The high proportion of Leptospirosis cases reflects the endemic nature of the disease in the Palghar district. This study shows seasonal trends in leptospirosis incidence over the year. The clinical presentation of leptospirosis may vary from sub-clinical to mild illness to severe and potentially fatal. The findings of this study will be important for achieving the overarching goal of One Health.

Impact of training on awareness and Knowledge of Birth Defects among Community Health Workers in tribal district of Maharashtra, India.

OBJECTIVE: Early identification, referrals and timely treatment is crucial to improve the outcome of Birth Defects (BDs). The role of Community Health Workers (CHWs) in India is largely fulfilled by Accredited Social Health Activists (ASHAs) who can play an important role in community-based reporting and referrals of BDs in newborn. In the study area, ASHAs have been previously trained for identification of BDs under Rashtriya Bal Swasthya Karyakram (RBSK); however, reporting through them was found to be sub-optimal. METHODS: To strengthen the community based reporting of BDs through ASHAs, audio visual based training was provided to 1225 ASHAs in 6 tribal blocks of Palghar district in Maharashtra, India. The change in knowledge about BDs before and after training among 1023 participants was analyzed using paired sample t test & McNemar test. RESULTS: Findings reveal a significant increase in the knowledge of participants with regards to prevention, risk factors and identification of BDs after intervention as compared to before intervention. DISCUSSION: The study suggests that audio-visual based refresher training increased knowledge of ASHAs with respect to identification, prevention and risk factors of BDs which may eventually improve reporting and referrals of BDs at community level.

Post-campaign coverage evaluation of a measles and rubella supplementary immunization activity in five districts in India, 2019-2020.

BACKGROUND: In alignment with the Measles and Rubella (MR) Strategic Elimination plan, India conducted a mass measles and rubella vaccination campaign across the country between 2017 and 2020 to provide a dose of MR containing vaccine to all children aged 9 months to 15 years. We estimated campaign vaccination coverage in five districts in India and assessed campaign awareness and factors associated with vaccination during the campaign to better understand reasons for not receiving the dose. METHODS AND FINDINGS: Community-based cross-sectional serosurveys were conducted in five districts of India among children aged 9 months to 15 years after the vaccination campaign. Campaign coverage was estimated based on home-based immunization record or caregiver recall. Campaign coverage was stratified by child- and household-level risk factors and descriptive analyses were performed to assess reasons for not receiving the campaign dose. Three thousand three hundred and fifty-seven children aged 9 months to 15 years at the time of the campaign were enrolled. Campaign coverage among children aged 9 months to 5 years documented or by recall ranged from 74.2% in Kanpur Nagar District to 90.4% in Dibrugarh District, Assam. Similar coverage was observed for older children. Caregiver awareness of the campaign varied from 88.3% in Hoshiarpur District, Punjab to 97.6% in Dibrugarh District, Assam, although 8% of children whose caregivers were aware of the campaign were not vaccinated during the campaign. Failure to receive the campaign dose was associated with urban settings, low maternal education, and lack of school attendance although the associations varied by district. CONCLUSION: Awareness of the MR vaccination campaign was high; however, campaign coverage varied by district and did not reach the elimination target of 95% coverage in any of the districts studied. Areas with lower coverage among younger children must be prioritized by strengthening the routine immunization programme and implementing strategies to identify and reach under-vaccinated children.

Experiences of sharing results of community based serosurvey with participants in a district of Maharashtra, India.

A growing number of organisations, including medical associations, recommend that research subjects should be given the option of being informed about the general outcome and results of the study. We recently completed a study involving nine serosurveys from 2018 to 2020 in five districts of India among three age groups (children 9 months to < 5 years; 5 to < 15 years of age, and women 15 to < 50 years of age before and after the measles and rubella (MR) vaccination campaigns). In Palghar district of Maharashtra all individuals in 30 selected clusters were enumerated, and 13 individuals per age group were randomly sampled. We established the procedures to return the results to the respondents for each stage of the survey. Of the 1,166 individuals selected for the measles and rubella serosurvey, 971 (83%) agreed to participate and were enrolled. Participants were informed that they will only be contacted if they test seronegative for measles and/or rubella antibodies. Overall, 140 individuals enrolled in the survey tested seronegative for IgG antibodies to measles and/or rubella viruses; were provided the reports and informed to seek medical advice. Upon follow up by phone, 10% (14) of the 140 participants reported to have been vaccinated. In this paper we discuss the procedures, experiences and considerations in returning results to participants in a community-based measles and rubella serosurvey. Although the lessons learned are specific to post measles-rubella vaccine campaign serosurvey in India, they might be helpful to those contemplating sharing results to participants of large scale survey settings.

Evaluating the effect of measles and rubella mass vaccination campaigns on seroprevalence in India: a before-and-after cross-sectional household serosurvey in four districts, 2018-2020.

BACKGROUND: India did phased measles-rubella supplementary immunisation activities (MR-SIAs; ie, mass-immunisation campaigns) targeting children aged 9 months to less than 15 years. We estimated measles-rubella seroprevalence before and after the MR-SIAs to quantify the effect on population immunity and identify remaining immunity gaps. METHODS: Between March 9, 2018 and March 19, 2020 we did community-based, cross-sectional serosurveys in four districts in India before and after MR-SIAs. 30 villages or wards were selected within each district, and one census enumeration block from each was selected as the survey cluster. Households were enumerated and 13 children in the younger age group (9 months to <5 years) and 13 children in the older ager group (5 to <15 years) were randomly selected by use of computer-generated random numbers. Serum samples were tested for IgG antibodies to measles and rubella viruses by enzyme immunoassay. FINDINGS: Specimens were collected from 2570 children before the MR-SIA and from 2619 children afterwards. The weighted MR-SIA coverage ranged from 73·7% to 90·5% in younger children and from 73·6% to 93·6% in older children. Before the MR-SIA, district-level measles seroprevalence was between 80·7% and 88·5% among younger children in all districts, and between 63·4% and 84·5% among older children. After the MR-SIA, measles seroprevalence among younger children increased to more than 90% (range 91·5 to 96·0) in all districts except Kanpur Nagar, in which it remained unchanged 80·4%. Among older children, measles seroprevalence increased to more than 90·0% (range 93·7% to 96·5%) in all districts except Hoshiarpur (88·7%). A significant increase in rubella seroprevalence was observed in all districts in both age groups, with the largest effect in Dibrugarh, where rubella seroprevalence increased from 10·6% to 96·5% among younger children. INTERPRETATION: Measles-rubella seroprevalence increased substantially after the MR-SIAs but the serosurvey also identified remaining gaps in population immunity.

Perceptions, awareness on snakebite envenoming among the tribal community and health care providers of Dahanu block, Palghar District in Maharashtra, India.

INTRODUCTION: India has remarkably the highest number of snakebite cases contributing to nearly 50% of the global snakebite deaths. Despite this fact, there is limited knowledge and awareness regarding the management practices for snakebite in the Indian population. The study aimed to explore the knowledge, awareness, and perception of snakes and snakebites, first aid, and treatment amongst the community and the frontline health workers in a tribal block of Dahanu, Maharashtra, India. METHODS: A cross-sectional study was carried out from June 2016 to October 2018 in the Dahanu Block, Maharashtra. Perceptions, knowledge, awareness, and first-aid practices on the snakebites among the community were studied through focus group discussions (FGDs). Semi-structured questionnaires were used to assess the knowledge, awareness, and experience of the traditional faith healers, snake rescuers, frontline health workers on the snakebites and their management. A facility check survey was conducted using pre-tested questionnaires for different levels of the government health care facilities. RESULTS: Most of the tribal community was aware of the commonly found snakes and their hiding places. However, there was inadequate knowledge on the identification and classification of venomous snakes. Belief in a snake god, the perception that snakes will not come out during thunderstorms, change in taste sensation, the ability of tamarind seeds or magnet to reduce the venom effect were some of the superstitions reported by the tribal community. The application of a harmful method (Tourniquet) as the first aid for snakebite was practiced by the tribal community. They preferred herbal medicines and visiting the traditional faith healers before shifting the patient to the government health facility. The knowledge on the ability to identify venomous snakebites and anti-venom was significantly higher amongst nurses and accredited social health activists (ASHAs) than auxiliary nurse midwives (ANMs) and multi-purpose workers (MPWs) (p < 0.05). None of the traditional faith healers; but nearly 60% of snake rescuers were aware of anti-venom. Fifty percent of the medical officers in Dahanu block did not have correct knowledge about the Krait bite symptoms, and renal complications due to the Russell viper bite. CONCLUSIONS: Inappropriate perception, inadequate awareness, and knowledge about snakes and snakebites may predispose the tribal community to increased risks of venomous snakebites. Unproven and harmful methods for snakebite treatment practiced by the community and traditional faith healers could be dangerous leading to high mortality. Therefore, a multi-sectoral approach of community awareness, mapping of vulnerable populations, capacity building of health care facility, empowerment of health care workers (HCWs) could be useful for reducing the mortality and morbidity due to snakebite envenoming in India.

Diagnostic Accuracy of Dried Blood Spots Collected on HemaSpot HF Devices Compared to Venous Blood Specimens To Estimate Measles and Rubella Seroprevalence.

Fingerprick blood spotted onto filter paper offers an alternative to venous blood for use in population-based surveillance because it is comparatively inexpensive, acceptable, and easy to manage in the field. Prior studies have shown excellent agreement for immunoglobulin G (IgG) antibody detection from dried blood spots (DBS) and venous blood samples. However, much of this evidence is from high-income settings or laboratories where the samples were unlikely to be exposed to extreme temperatures and humidity, factors known to degrade DBS. We report the diagnostic accuracy of DBS collected using HemaSpot HF devices against venous sera in measuring measles- and rubella-specific IgG antibodies in a household serosurvey conducted in two districts in India. Paired serum and DBS samples collected by fingerprick were collected from women aged 15 to 50 years enrolled in a serosurvey in Palghar District of Maharashtra and Kanpur Nagar District of Uttar Pradesh in India. Specimen quality and volume were assessed in the laboratory. Samples were tested for antimeasles and antirubella IgG antibodies by an enzyme-linked immunosorbent assay (ELISA) (Euroimmun). Sensitivity of antibody detection by DBS was greater than 98%, and specificity was 90% and 98%, for measles and rubella IgG, respectively. Antibody concentrations were strongly correlated between paired specimens with adequate volume (measles R2 = 0.94; rubella R2 = 0.89). Although correlation was poor if DBS specimens had lower volumes, impact on qualitative results was minimal. This study showed DBS collected with HemaSpot HF devices can generate highly accurate results of measles- and rubella-specific IgG compared to sera in community-based surveys when protocols are optimized for DBS specimens. IMPORTANCE Dried blood spot (DBS) collection provides an easy, practical, and acceptable alternative to venous blood collection, especially for community-based studies, provided that results from DBS are accurate. We demonstrated high sensitivity and specificity for measles- and rubella-specific immunoglobulin G (IgG) with DBS collected via HemaSpot HF devices compared to serum samples. This is one of the largest community-based diagnostic accuracy studies of measles and rubella antibody testing with DBS and the first application we are aware of using HemaSpot HF device for measles and rubella serology. Results support the use of DBS in community-based serosurveillance.

Perspectives of primary healthcare providers on implementing cancer screening services in tribal block of Maharashtra, India.

BACKGROUND: Breast, cervical, and oral cancers contribute to majority of cancer deaths among women in India. However, there is poor implementation of screening programs at primary health care (PHC). There is a need to understand the perspectives of healthcare providers at PHC level for feasibility of implementation of a cost-effective cancer screening program, particularly in the rural and tribal areas that are under served by cancer services. MATERIALS AND METHODS: A continuous medical education (CME) program on "Prevention and early detection of common cancers" was held for all Medical Officers of Palghar District, Maharashtra. A self-administered questionnaire was used to assess the knowledge, attitude, practices, perspectives regarding common cancers, screening methods, and human papilloma virus (HPV) vaccination. A pre- and post-assessment was carried out before the commencement and on completion of the CME among 76 participants. RESULTS: Knowledge about etiology of common cancers was high; however, awareness of risk factors was low. There were knowledge gaps about HPV vaccination. There was overall improvement about the available screening methods and knowledge of HPV vaccine and dosages after the CME (pretest 65% to posttest 95%). Providers had no experience in performing cervical cancer screening on a routine basis. While the majority of the providers (97%) indicated that screening for cancer was essential and feasible at PHC level; however, training (52%) and resources (53%) would be needed. CONCLUSION: Healthcare providers though from the underserved tribal areas, were optimistic to implement screening for common cancers and were willing to take training for the same. This emphasizes the need for educating and training the healthcare providers with simple techniques for effective implementation of cancer screening programs in underserved areas.
