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

Comparative Study on Non-Linear Time History Analysis of a Building With and Without Base Isolation using ETABS

Abstract Base isolation is a device which is used to discrete the building from its foundation. Therefore, all through seismic activity, the building does not change due to the earthquake. Even if the earth moves violently, buildings tend to move like rigid bodies instead of collapsing In the current study, reinforced concrete framed structures of G + 8 and G + 16 (with and without base isolation) are considered with a 3 m high floor in the seismic zone V. The base isolator for both structures is designed to determine the stiffness and physical magnitudes of the lead rubber bearing core (LRB) specified at the base of the frame. The buildings were analyzed using nonlinear time history technique in ETABS. The effect of Base isolator is studied and building reactions like storey displacements, storey shear, storey drifts, and overturning moments can be seen in graphs. A general examination of G+8 and G+16 buildings with and without base isolator is watched.</jats:p

A phase 4 study to evaluate outpatient blinatumomab in patients with minimal/measurable residual disease (MRD) positivity (+) of B-cell precursor acute lymphoblastic leukemia (BCP-ALL).

TPS7051 Background: The prognosis for adults with relapsed or refractory BCP-ALL is poor. MRD+ is the strongest predictor of relapse. Blinatumomab, a CD3/CD19-directed BiTE® (bispecific T-cell engager) molecule, is an effective treatment for patients with MRD+.1 Blinatumomab is administered as a continuous intravenous infusion (cIV) 28 days per cycle. Severe adverse events (AEs) such as cytokine release syndrome (CRS) and neurologic toxicity (NT) may occur; thus, hospitalization is recommended for the first 3 days of cycle 1 and the first 2 days of cycle 2 for MRD+ patients. However, the incidence of severe AEs is low in MRD+ BCP-ALL patients (CRS: 2%, NT: 13%).1 We believe that with the use of effective digital monitoring devices, blinatumomab can be safely administered for the entire 28-day cIV cycle as an outpatient. Methods: Adult patients (n = 45) with BCP-ALL in complete remission and MRD+ (≥0.1% blasts) are being enrolled at 25 planned treatment sites, endpoint: grade ≥3 AE during monitoring (Amgen NCT04506086). Patient suitability for blinatumomab and outpatient monitoring is established. Patients will receive 2-4 cycles of blinatumomab. Cycles are initiated in the outpatient setting, digital monitoring devices activated and attached, and patients sent home. Once home, patients set up the home hub and real-time remote data transfer to the healthcare professional (HCP) begins. The devices are worn continuously, 24 hours a day for the first 3 days of cycle 1 and the first 2 days of cycle 2 only. Devices: Current Health’s Wearable Monitoring System (CHWMS) is an FDA-cleared platform for wireless and wearable health monitoring of patients at home. The CHWMS provides continuous oxygen saturation, respiratory rate, and heart rate; an axillary temperature sensor is worn and provides continuous temperature. Patients manually measure blood pressure every 3-6 hours around the clock. Patients have an integrated mobile device (tablet) to initiate contact with the HCP if needed. HCP/designee has a mobile device (smart phone) and receives vital signs as a constant live feed transmitted from the CHWMS device. The CHWMS platform generates a loud audible alert based on pre-specified vital sign alarming thresholds or if there is an interruption in data transfer. HCP may initiate direct audio and video contact with the patient, assess the patient’s condition, and make an appropriate intervention. HCP may also initiate patient contact in the absence of an alert. Patients are required to have a caregiver present during the entire period of outpatient monitoring. Patients have a full set of replacement devices as well as a 24/7 hotline for device support. Trial enrollment is underway. This study may generate feasibility data on the effectiveness of home monitoring during blinatumomab infusion in patients with MRD+ BCP-ALL. 1Gökbuget, Blood, 2018.

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
