Study of water supply & sanitation practices in India using geographic information systems: some design & other considerations in a village setting

Background & objectives: Availability of clean water and adequate sanitation facilities are of prime importance for limiting diarrhoeal diseases. We examined the water and sanitation facilities of a village in southern India using geographic information system (GIS) tools. Methods: Places of residence, water storage and distribution, sewage and places where people in the village defaecated were mapped and drinking water sources were tested for microbial contamination in Nelvoy village, Vellore district, Tamil Nadu. Results: Water in the village was found to be microbiologically unfit for consumption. Analysis using direct observations supplemented by GIS maps revealed poor planning, poor engineering design and lack of policing of the water distribution system causing possible contamination of drinking water from sewage at multiple sites. Interpretation & conclusions: Until appropriate engineering designs for water supply and sewage disposal to suit individual village needs are made available, point-of-use water disinfection methods could serve as an interim solution

Crossing boundaries:bras, lingerie and rape myths in postcolonial urban middle-class India

With the processes of modernization, urbanization and the entry of women in the formal labour market in Indian metropolitan spaces, this paper examines how the modern middle-class woman’s sartorial choices become enmeshed in popular rape myths (false beliefs) that serve to blame her for the wearing of western clothing. The paper articulates the ways in which middle-class women’s social realities are shaped by historical, colonial and nationalist ideologies of modernization, constructed and mediated through moral codes of dressing. By drawing upon original and contemporary empirical narratives from the urban spaces of Delhi and Mumbai, we emphasise how everyday sartorial choices, in relation to particularly the bra and lingerie, can reveal the nuanced ways in which Urban Indian Professional Women (UIPW) seek to understand, negotiate, and resist patriarchal power. Our findings shed light on conflicting and contradictory spatial experiences, where some women internalize and negotiate moral codes of dressing, out of fear, and others who transgress are subject to sanctions. Given the paucity of scholarly literature in this area, the paper makes an important theoretical and empirical contribution with its focus on postcoloniality and everyday discursive material spaces of gendered and sexualized dress practices. It argues for the consciousness raising of everyday urban geographies of dress that reveal complicated structures of power that are often deemed hidden

Prevalence, Mortality, and Access to Care for Chronic Kidney Disease in Medicaid-Enrolled Adults With Sickle Cell Disease in California: Retrospective Cohort Study

BackgroundChronic kidney disease (CKD) is a significant complication in patients with sickle cell disease (SCD), leading to increased mortality. ObjectiveThis study aims to investigate the burden of CKD in Medicaid-enrolled adults with SCD in California, examine differences in disease burden between male and female individuals, and assess mortality rates and access to specialized care. MethodsThis retrospective cohort study used the California Sickle Cell Data Collection program to identify and monitor individuals with SCD. Medicaid claims, vital records, emergency department, and hospitalization data from 2011 to 2020 were analyzed. CKD prevalence was assessed based on ICD (International Classification of Diseases) codes, and mortality rates were calculated. Access to specialized care was examined through outpatient encounter rates with hematologists and nephrologists. ResultsAmong the 2345 adults with SCD, 24.4% (n=572) met the case definition for CKD. The SCD-CKD group was older at the beginning of this study (average age 44, SD 14 vs 34, SD 12.6 years) than the group without CKD. CKD prevalence increased with age, revealing significant disparities by sex. While the youngest (18-29 years) and oldest (>65 years) groups showed similar CKD prevalences between sexes (female: 12/111, 10.8% and male: 12/101, 11.9%; female: 74/147, 50.3% and male: 34/66, 51.5%, respectively), male individuals in the aged 30-59 years bracket exhibited significantly higher rates than female individuals (30-39 years: 49/294, 16.7%, P=.01; 40-49 years: 52/182, 28.6%, P=.02; and 50-59 years: 76/157,48.4%, P<.001). During this study, of the 2345 adults, 435 (18.5%) deaths occurred, predominantly within the SCD-CKD cohort (226/435, 39.5%). The median age at death was 53 (IQR 61-44) years for the SCD-CKD group compared to 43 (IQR 33-56) years for the SCD group, with male individuals in the SCD-CKD group showing significantly higher mortality rates (111/242, 45.9%; P=.009) than female individuals (115/330, 34.9%). Access to specialist care was notably limited: approximately half (281/572, 49.1%) of the SCD-CKD cohort had no hematologist visits, and 61.9% (354/572) did not see a nephrologist during this study’s period. ConclusionsThis study provides robust estimates of CKD prevalence and mortality among Medicaid-enrolled adults with SCD in California. The findings highlight the need for improved access to specialized care for this population and increased awareness of the high mortality risk and progression associated with CKD

Real-World Data of Crizanlizumab in Sickle Cell Disease: A Single-Center Analysis

BackgroundCrizanlizumab was approved by the United States Food and Drug Administration agency in 2019 for decreasing vaso-occlusive events (VOEs) in sickle cell disease (SCD). Data regarding the use of crizanlizumab in the real-world setting are limited. Our goal was to identify patterns of crizanlizumab prescriptions in our SCD program and evaluate the benefits and identify barriers to its use in our SCD clinic.MethodsWe conducted a retrospective analysis of patients who received crizanlizumab at our institution between July 2020 and January 2022. We compared acute care usage patterns before and after initiation of crizanlizumab, adherence to treatment, discontinuation and reasons for discontinuation. High utilizers of hospital-based services were defined as those with more than one visit to the emergency department (ED) per month or more than three visits to the day infusion program per month.ResultsFifteen patients received at least one dose of crizanlizumab 5 mg/kg of actual body weight during the study period. The average number of acute care visits decreased following crizanlizumab initiation but was not statistically significant (20 visits vs. 10 visits, P = 0.07). Among high users of hospital-based services, the average number of acute care visits decreased after initiation of crizanlizumab (40 vs. 16, P = 0.005). Only five patients included in this study remained on crizanlizumab 6 months after initiation.ConclusionOur study suggests that crizanlizumab use may be helpful in decreasing acute care visits in SCD, particularly among high utilizers of hospital-based acute care services. However, the discontinuation rate in our cohort was extremely high, and further evaluation of efficacy and causes contributing to discontinuation in larger cohorts is warranted

Water handling, sanitation and defecation practices in rural southern India: a knowledge, attitudes and practices study

Diarrhoea and water-borne diseases are leading causes of mortality in developing countries. To understand the socio-cultural factors impacting on water safety, we documented knowledge, attitudes and practices of water handling and usage, sanitation and defecation in rural Tamilnadu, India, using questionnaires and focus group discussions, in a village divided into an upper caste Main village and a lower caste Harijan colony. Our survey showed that all households stored drinking water in wide-mouthed containers. The quantity of water supplied was less in the Harijan colony, than in the Main village (P &lt; 0.001). Residents did not associate unsafe water with diarrhoea, attributing it to 'heat', spicy food, ingesting hair, mud or mosquitoes. Among 97 households interviewed, 30 (30.9%) had toilets but only 25 (83.3%) used them. Seventy-two (74.2%) of respondents defecated in fields, and there was no stigma associated with this traditional practice. Hand washing with soap after defecation and before meals was common only in children under 15 years (86.4%). After adjusting for other factors, perception of quantity of water received (P &lt; 0.001), stated causation of diarrhoea (P = 0.02) and low socio-economic status (P &lt; 0.001) were significantly different between the Main village and the Harijan colony. Traditional practices may pose a significant challenge to programmes aimed at toilet usage and better sanitation

Grndad and Disease Modifying Therapy (DMT): Shifts in Dmt Are Seen at the Adolescent/Young Adult Transition in Sickle Cell Disease in a Multi-Site Prospective Registry

The ability to characterize the modern person living with SCD in the US has been limited by the lack of a well-curated longitudinal registry. The Globin Research Network for Data and Discovery ( GRNDaD) registry aims to overcome this challenge by collecting data from the now 53 IRB-approved centers across the US in collaboration with the National Alliance of Sickle Cell Centers (NASCC) and the HRSA-funded Sickle Cell Disease Treatment Demonstration Project Grant. Here, we describe the use of disease-modifying therapy in (actively consented) adults and children with Hgb SS/ SB 0 thalassemia (SCA) from 37 sites. Methods: Each site consents subjects and enters extensive baseline data including SCD complications and labs, subjects also complete patient-reported outcomes (PROs)-both at baseline and annually. Each subject is expected to have an annual follow-up where data is extracted from the Electronic Health Record (EHR). All data is stored in REDCap and, for this abstract, data were extracted into R on all active subjects (data entry in the last two years) who have complete minimum data collected. Median values were compared using Mann-Whitney U tests. Disease-modifying therapy (DMT) in this study comprises hydroxyurea (HU), chronic red blood cell (RBC) transfusions, crizanlizumab, L-glutamine, and voxelotor. Results: There are 2501 active patients in GRNDaD. Twenty-six percent of subjects are pediatric </= 18 years of age, 55.5% are female and 66.7% have HgbSS or HgbSB 0 thalassemia (SCA). Here, we report data on people with SCA only, whose minimum data were complete (n=1272). Table 1 shows DMT by age. 187 (21%) adults and 31 (8.5%) children were not on DMT. Figure 2 is a box plot of the absolute neutrophil count (ANC) comparing adults and children who are and are not taking HU. Adults on HU had significantly lower ANCs than those not on HU (median = 4.4 (IQR: 3.07, 6.3) v 6.6 (IQR:4.07, 8.14), p<0.001) (Figure). Similar findings were observed for children ( median = 3.5 (IQR:2.5, 5.7) Vs 8.1 (5.8, 12.8) , p =0.04) Both children and adults on HU had higher MCVs than those not on HU (median for peds: 91.5 (IQR: 85.1, 98.75) v 86 (IQR: 83.3, 86.1), p=0.05, median for adults: 96.5 (IQR: 89, 107) v 90 (IQR: 86.1, 95.1), p<0.001). We compared hemoglobin for those on and off HU, and on and off voxelotor, excluding patients on chronic transfusion therapy. There was a statistically significant difference in hemoglobin when comparing on or off of HU (median 8.9 g/dl (IQR 7.95, 9.9) v 8.2 g/dl (IQR: 7.2, 9.7, p =0.047)). There were no statistically significant differences in hemoglobin when comparing subjects on or off of voxelotor (median = 8.4 g/dl (IQR: 7.5, 9.6) vs 7.9 (IQR: 7.4, 9.8), p =0.57). In the adults, there were statistically significantly more males than females on HU, but there were no differences seen in the pediatric cohort. Examining DMT by age group, chronic RBC transfusion use doubled from the 11-17 age group to the 18-29-year age group (12% to 25%) and HU use decreased (83%-59%) over this same period. Limitations: This cohort may over-represent those on DMT as those enrolled in GRNDaD were more likely to have clinic visits. Discussion: GRNDaD has doubled the number of sites consenting subjects and entering data over the last year. The number is expected to increase again in the next 12 months, as an additional 15 sites are already IRB-approved with a goal to include all SCD centers in NASCC. This cross-sectional description of the current population of people living with SCD and treated in NASCC-recognized SCD centers in the US shows that the majority of those with SCA are receiving DMT. There is a noticeable decrease in HU use during the transition period with an increase in the use of chronic transfusion therapy. Newer DMT has had limited uptake in this cohort. The next steps will be to provide longitudinal data on this population and examine associations of DMT and important clinical outcomes including PROs
