Total 63 articles were selected from databases and 34 articles from various other sources.Findings: Scientists observed genomic variations including common mutations in ORF1ab, ORF1a, ORF3a, and S genes, while several unique mutations exist in most isolates from these countries. Demographic analysis showed that the majority of the infected individuals were male and younger adults (20 to 40 years). India had both the highest number of deaths and incidents while Afghanistan had the highest fatality rate (4.37%). Various molecular assay (rRT-PCR), antigen, and antibody-based assays have been developed to facilitate early screening due to the unavailability of any effective treatments. Although every country tried to undertake imperative preventive measures along with vaccination drives, many of them still face grave repercussions due to scarcity of health facilities, under-developed infrastructures, and improvident government policies.

The secondary objective was to determine factors contributing to stigma during motherhood among HIV-infected women as well as explore how they cope with the discrimination from society.Design/methodology/approachQualitative data were collected using in-depth interviews to obtain different versions of stigmatized experience from 16 pregnant women living with HIV on stigmatization and coping mechanisms. There were 5 pregnant adolescents living with HIV and 11 adult pregnant women living with HIV. The content analysis was used to examine patterns of stigmatizations and attributed factors.FindingsPersonal stigma was found among pregnant women living with HIV regardless of age. HIV status disclosure was the crucial barrier of accessing to care for people experiencing stigmatizations. Personal stigma associated with higher HIV status was not disclosed. Interestingly, all teenage mothers who participated in this study disclosed their HIV-status to their family. People who have social support especially from family and significant others are found to be able to cope and get through the difficulties better than those who lack those social support.Originality/valueThis study yields outcomes similar to several other studies that have been conducted either in Thailand or other countries.

Text-based telehealth interventions (TTIs) seem to provide a low-cost and convenient treatment option; however, the evidence is scarce. This study aimed to synthesize evidence relating to the use of TTIs for the management of EDs.Design/methodology/approachFive databases were searched published between January 2020 and May 2019. The authors used keywords relating to telehealth and EDs. The authors used Joanna Briggs Institute's (JBI's) critical appraisal instrument to assess the methodology quality of included studies.FindingsFifteen studies were included in this mix-method systematic review and assessed for methodology quality. Email, web-based texting, text-messaging and online chat room were used as mode for deliver healthcare for patients with EDs. In the treatment phase, all studies (nine studies; n = 860 participants) showed effectiveness (for RCTs) and usefulness (for non-RCT studies). In the aftercare phase (six studies; n = 364 participants), the results regarding the effectiveness of TTIs were mixed. Two studies showed effectiveness whilst four studies did not find statistically significant change of ED outcomes.Research limitations/implicationsThe qualities of these studies varied; firstly, 66% (n = 10) of the studies were non-randomized studies (e.g. single-arm trial, case report) with small samples. Moreover, one-fourth (n = 4) of the studies did not use validated instruments or indicate the instrument. Also, half (n = 7) of the studies used TTIs as adjunct to face-to-face treatment or bigger online treatment, it is hard to make conclusion that the changes were due to TTIs' effect. In addition, follow-up rate is not satisfactory, thus results should be interpreted cautiously.Practical implicationsTTIs seem to be promising for management of EDs, particularly in the treatment phase. This provides an important treatment option for health practitioners and people with EDs as an alternative or in adjunct with face-to-face services.Originality/valueThis is the first review to synthesis the use of TTIs for ED management.","PeriodicalId":15935,"journal":{"name":"Journal of Health Research","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42643250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multivariate analysis of logistic regression was adopted to find the correlates of health insurance for all the eight (8) north-eastern states of India.FindingsThe results observed that among the north-eastern states, the coverage of health insurance was highest in Arunachal Pradesh (59%) followed by Tripura (58%), Mizoram (47%) surpassing the all India level of 27%, whereas the lowest was in Manipur (4%) followed by Nagaland (6%) and Assam (10%). The multivariate analysis of logistic regression found that the socioeconomic and demographic factors, households with a bank account and below poverty line (BPL) cardholders played a significant role in the coverage of health insurance in the north-eastern states of India.Research limitations/implicationsThe study focuses only on the coverage and correlates of health insurance. Further evaluation studies on each scheme of the social health insurance are needed for proper assessment of the health insurance schemes in the region.Practical implicationsThere has been evidence around the world (South Korea, Taiwan and Thailand) that health insurance could be a protective shield from the entrapment into poverty due to high health expenditure. The NFHS-4 put up the finding that in the north-eastern part of India, the coverage of health insurance had been low. This implied that the region could fall into poverty due to high medical expenses on health. Taking account of multiple health insurance providers, risk pooling and consolidation of health insurance providers have become the need of the hour.Originality/valueThe study is different from other studies of health insurance since it covered all the eight (8) north-eastern states of India, which are ethnically, culturally and historically distinct from the rest of India in general and within the region and states in particular and examines the impact of each of the independent variables with the dependent variables.
