    The main objective of this study is to produce interlock fabrics with two different types of material at the face and back and to evaluate the effectiveness of its air permeability and thermal properties, which, in turn, decide the comfort of the wearer. It is observed that the tightness factor of the fabric has a linear relationship with air permeability, thermal conductivity and Qmax. The polyester modal interlock fabric shows a higher Qmax value which provides a good warm-cool effect, that is important for sportswear applications.

    SummaryObjectivesThis study sought to document the clinical and laboratory manifestations, genetic variability, and outcomes of scrub typhus, an often severe infection caused by Orientia tsutsugamushi, in South India.MethodsPatients admitted to a large teaching hospital with IgM ELISA-confirmed scrub typhus were evaluated. Clinical examination with a thorough search for an eschar, laboratory testing, chest X-ray, and outcome were documented and analyzed. Additionally, a 410-bp region of the 56-kDa type-specific antigen gene of O. tsutsugamushi was sequenced and compared with isolates from other regions of Asia.ResultsMost of the 154 patients evaluated presented with fever and non-specific symptoms. An eschar was found in 86 (55%) patients. Mild hepatic involvement was seen in most, with other organ involvement including respiratory, cardiovascular, and renal. Multi-organ dysfunction was noted in 59 (38.3%), and the fatality rate was 7.8%. Hypotension requiring vasoactive agents was found to be an independent predictor of mortality (p<0.001). The phylogeny of 26 samples showed 17 (65%) clustering with the Kato-like group and eight (31%) with the Karp-like group.ConclusionsThe presentation of scrub typhus can be variable, often non-specific, but with potentially severe multi-organ dysfunction. Prompt recognition is key to specific treatment and good outcomes. Further study of the circulating strains is essential for the development of a successful vaccine and sensitive point-of-care testing

    Early detection of colorectal cancer can significantly facilitate clinicians’ decision-making and reduce their workload. This can be achieved using automatic systems with endoscopic and histological images. Recently, the success of deep learning has motivated the development of image- and video-based polyp identification and segmentation. Currently, most diagnostic colonoscopy rooms utilize artificial intelligence methods that are considered to perform well in predicting invasive cancer. Convolutional neural network-based architectures, together with image patches and preprocesses are often widely used. Furthermore, learning transfer and end-to-end learning techniques have been adopted for detection and localization tasks, which improve accuracy and reduce user dependence with limited datasets. However, explainable deep networks that provide transparency, interpretability, reliability, and fairness in clinical diagnostics are preferred. In this review, we summarize the latest advances in such models, with or without transparency, for the prediction of colorectal cancer and also address the knowledge gap in the upcoming technology

    Investigating violence against _Accredited Social Health Activists_ (ASHAs): a mixed methods study from rural North Karnataka, India

    Get PDF
    # Background Accredited Social Health Activists (ASHAs) are female community health workers who primarily work to improve local reproductive, maternal, neonatal, and child health across India. As ASHAs often hail from patriarchal environments and are positioned at the bottom of the healthcare hierarchy, they are vulnerable to experiencing different forms of violence from the various individuals that they interact with. There is a gap in knowledge about the violence ASHAs experience. The purpose of this study was to assess the working condition of ASHAs, the extent and types of violence they experienced, and the corresponding perpetrators of this violence in two districts of Northern Karnataka. # Methods Using a mixed methods approach, we first surveyed 396 ASHAs to characterize their experiences of violence. We then conducted in-depth interviews with 16 ASHAs to elaborate on survey findings. Data was analyzed using quantitative prevalence statistics and qualitative thematic analysis. # Results The majority of ASHAs reported economic (88%) or emotional violence (73%), while many ASHAs reported sexual (32%) or physical violence (26%). ASHAs reported high levels of economic violence from their beneficiaries and their beneficiaries’ families (64%), emotional violence from their co-workers (44%), and physical and sexual violence from their husbands (17% and 12% respectively). Mixed methods findings revealed that violence was often rooted from their low positioning on the healthcare hierarchy, a lack of respect from community members, and limited autonomy at home. # Conclusions Evidence from this study suggests that violence perpetrated against ASHAs is highly prevalent, diverse in forms, and often arises from the ASHA’s immediate circles. Interventions aiming to decrease violence against ASHA workers requires multi-level approach, with collaborative components empowering ASHAs, sensitizing ASHA families and co-workers, implementing regulations at the health facility level, and increasing community-wide respect for ASHAs and their role in the health care

    Introduction: Samvedana Plus is a multi-level intervention working with sex workers, their intimate partners (IP) and communities to reduce intimate partner violence (IPV) and increase condom use within intimate relationships of sex workers in Northern Karnataka, India. Methods: A cluster randomised control trial (cRCT) in 47 villages. Female sex workers with an IP in the last 6 months were eligible for baseline (2014), midline (2016) and endline (2017) surveys. 24 villages were randomised to Samvedana Plus and 23 to a wait-list control. Primary outcomes among sex workers included: experience of physical and/or sexual IPV or severe physical/sexual IPV in the last 6 months; consistent condom use with their IP in past 30 days. Analyses adjusted for clustering, and baseline cluster level means of outcomes. Result: Baseline (n=620) imbalance was observed in respect to age (33.9 vs. 35.2) and IPV (31.4% vs. 45.0%). No differences in physical/sexual IPV (8∙1% vs 9∙0%), severe physical/ IPV (6∙9% vs 8∙7%), or consistent condom use with IPs (62∙5% vs 57∙3%) were observed by trial arm at endline (n=547). Samvedana Plus was associated with decreased acceptance of IPV (AOR=0∙62, 95% CI 0∙40-0∙94, p=0∙025), increased awareness of self-protection strategies (AOR=1∙73, 95% CI=1∙04-2∙89, p=0.035), and solidarity of sex workers around issues of IPV (AOR=1∙69, 95% CI=1∙02-2∙82, p=0∙042). We observed an increase in IPV between baseline (25∙9%) and midline (63∙5%) among women in Samvedana Plus villages but lower in comparison villages (41∙8% to 44∙3%) and a sharp decrease at endline in both arms (~7%). Conclusion: We found no evidence that Samvedana Plus reduced IPV or increased condom use, but itmay impact acceptance of IPV, increase knowledge of self-protection strategies and increase sex worker solidarity. Inconsistencies in reported IPV undermined the ability of the trial to assess effectiveness. Trial registration: NCT0280725

    Economic evaluation of implementing a rapid point-of-care screening test for the identification of hepatitis C virus under National Viral Hepatitis Control Programme in Tamil Nadu, South India

    Introduction: Viral hepatitis is a crucial public health problem in India. Hepatitis C virus (HCV) elimination is a national priority and a key strategy has been adopted to strengthen the HCV diagnostics services to ensure early and accurate diagnosis. Methods: To conduct an economic evaluation of implementing a rapid point-of-care screening test for the identification of HCV among the selected key population under the National Viral Hepatitis Control Programme in Tamil Nadu, South India. Economic evaluation of a point-of-care screening test for HCV diagnosis among the key population attending the primary health care centers. A combination of decision tree and Markov model was developed to estimate cost-effectiveness of point-of-care screening test for HCV diagnosis at the primary health care centers. Total costs, quality-adjusted life years (QALYs) of the intervention and comparator, and incremental cost-effectiveness ratio (ICER) were calculated. The model parameter uncertainties which would influence the cost-effectiveness outcome has been evaluated by one-way sensitivity analysis and probabilistic sensitivity analysis. Results: When compared to the tertiary level diagnostic strategy for HCV, the point-of-care screening for selected key population at primary health care level results in a gain of 57 undiscounted QALYs and 38 discounted QALYs, four undiscounted life years and two discounted life years. The negative ICER of the new strategy indicates that it is less expensive and more effective compared with the current HCV diagnosis strategy. Conclusions: The proposed strategy for HCV diagnosis in the selected key population in Tamil Nadu is dominant and cost-saving compared to the current strategy

    What determines violence among female sex workers in an intimate partner relationship? Findings from North Karnataka, south India.

    BACKGROUND: Like other women in India, female sex workers (FSWs) frequently experience violence from their intimate partners (IPs)-a reality that increases their risk of acquiring HIV or other sexually transmitted infections. Less is known about the nature of these intimate relationships or what aspect of the relationship increases the risk of IP violence (IPV). We measured the prevalence and determinants of IPV on FSWs in the context of north Karnataka, India, characterized by high HIV-prevalence and extreme poverty. METHODS: Overall 620 FSWs with an IP participated in a baseline survey conducted for an on-going cluster-randomised controlled trial aiming to evaluate the impact of a multi-level intervention on IPV reduction. We characterize the nature of intimate relationships and explored determinants of severe physical and/or sexual IP violence using univariable and multivariable analyses. RESULTS: The median age of participants was 35 years with 10 years of duration in an intimate relationship. Though most relationships originated from a sex work encounter, 84% stated that IPs did not know they were currently practicing sex work. In past 6 months, the experience of emotional violence was 49% (95%CI:45.2-53.2), physical 33% (95%CI:29.5-37.1) and sexual violence 7% (95%CI:4.8-8.9), while 24% (95%CI:21.0-27.9) FSWs experienced recent severe physical and/or sexual violence from IPs. Factors associated with recent IPV included experience of physical and/or sexual violence from their clients in last 6 months (AOR 2.20; 95%CI: 1.29-3.75), sexual intercourse in the past 1 month when their IP was under the influence of alcohol (AOR 2.30; 95%CI: 1.47-3.59) and providing financial support to their IP (AOR 2.07; 95%CI: 1.28-3.34). CONCLUSIONS: The association between increased risk of violence and provision of financial support to an IP is indicative of gendered power dynamics as men remain dominant irrespective of their financial dependency on FSWs. Interventions are needed that address inequitable gender norms which makes FSWs tolerate violence even though she is not financially dependent on IP. Higher likelihood of violence in presence of alcohol use and FSWs' previous experience of workplace violence linked to IPV call for strengthening the crisis management systems within community-based organisations that can address all forms of violence and associated risk factors.

    Background: Twenty-two million Americans have limited English proficiency. Interpreting for limited English proficient patients is intended to enhance communication and delivery of quality medical care. Objective: Little is known about the impact of various interpreting methods on interpreting speed and errors. This investigation addresses this important gap. Design: Four scripted clinical encounters were used to enable the comparison of equivalent clinical content. These scripts were run across four interpreting methods, including remote simultaneous, remote consecutive, proximate consecutive, and proximate ad hoc interpreting. The first 3 methods utilized professional, trained interpreters, whereas the ad hoc method utilized untrained staff. Measurements: Audiotaped transcripts of the encounters were coded, using a prespecified algorithm to determine medical error and linguistic error, by coders blinded to the interpreting method. Encounters were also timed. Results: Remote simultaneous medical interpreting (RSMI) encounters averaged 12.72 vs 18.24 minutes for the next fastest mode (proximate ad hoc) (p = 0.002). There were 12 times more medical errors of moderate or greater clinical significance among utterances in non-RSMI encounters compared to RSMI encounters (p = 0.0002). Conclusions: Whereas limited by the small number of interpreters involved, our study found that RSMI resulted in fewer medical errors and was faster than non-RSMI methods of interpreting

    Mental health, physical impairment and violence among FSWS in North Karnataka, South India: a story of intersecting vulnerabilities

    AimsThis study examines the prevalence and associations between recent violence experience, mental health and physical health impairment among Female Sex Workers (FSWs) in north Karnataka, India.BackgroundMulti-morbidity, in particular the overlap between physical and mental health problems, is an important global health challenge to address. FSWs experience high levels of gender-based violence, which increases the risk of poor mental health, however there is limited information on the prevalence of physical health impairments and how this interacts with mental health and violence.MethodWe conducted secondary analysis of cross-sectional quantitative survey data collected in 2016 as part of a cluster-RCT with FSWs called Samvedana Plus. Bivariate and multivariate analyses were used to examine associations between physical impairment, recent (past 6 months) physical or sexual violence from any perpetrator, and mental health problems measured by PHQ-2 (depression), GAD-2 (anxiety), any common mental health problem (depression or anxiety), self-harm ever and suicidal ideation ever.Result511 FSWs participated. One fifth had symptoms of depression (21.5%) or anxiety (22.1%), one third (34.1%) reported symptoms of either, 4.5% had ever self-harmed and 5.5% reported suicidal ideation ever. Over half (58.1%) reported recent violence. A quarter (27.6%) reported one or more chronic physical impairments. Mental health problems such as depression were higher among those who reported recent violence (29%) compared to those who reported no recent violence (11%). There was a step-wise increase in the proportion of women with mental health problems as the number of physical impairments increased (e.g. depression 18.1% no impairment; 30.2% one impairment; 31.4% ≥ two impairments). In adjusted analyses, mental health problems were significantly more likely among women who reported recent violence (e.g. depression and violence AOR 2.42 (1.24–4.72) with rates highest among women reporting recent violence and one or more physical impairments (AOR 5.23 (2.49–10.97).ConclusionOur study suggests multi-morbidity of mental and physical health problems is a concern amongst FSWs and is associated with recent violence experience. Programmes working with FSWs need to be mindful of these intersecting vulnerabilities, inclusive of women with physical health impairments and include treatment for mental health problems as part of core-programming.Samvedana Plus was funded by UKaid through Department for International Development as part of STRIVE (structural drivers of HIV) led by London School of Hygiene and Tropical Medicine and the What Works to Prevent Violence Against Women and Girls Global Programme led by South African Medical Research Council</jats:sec
