: Introduction: To achieve epidemic control of infectious diseases, engaging higher‐burden populations with accessible diagnostic services is critical. HIV self‐testing (HIVST) is a promising option. Methods: We implemented an online HIVST programme for key populations across India. Eligible clients were 18 years or older, self‐reported a negative or unknown HIV status and reported not taking antiretroviral therapy. Clients who reported a prior HIV diagnosis were not eligible to receive an HIVST kit. HIVST clients received kits via courier or in person at pre‐determined pick‐up points supported by trained counselling staff. Virtual counsellors engaged clients online and by phone and offered support to register, access, and complete HIVST free of cost. Virtual counsellors supported clients to report results and engage with follow‐up services. Follow‐up included linking clients with a positive result to confirmatory testing and HIV care services. We assessed programmatic data across HIV continuum outcomes and conducted a qualitative evaluation through interviews with purposively sampled clients. Results: Between 30 June 2021 and 30 September 2022, 5324 clients ordered an HIVST kit (76% men, 13% women, 7% transgender people, 4% unknown gender). Of the 4282 clients reporting results (94% of those who received a kit), 6% screened positive, among whom 72% (n = 184) completed confirmatory testing. Themes from 41 client interviews included satisfaction about the convenience and privacy of services and the discreet nature of kit delivery. Respondents were drawn to the convenience of HIVST and appreciated gaining courage and comfort throughout the process from virtual counsellor support. For respondents who screened positive, challenges to care linkage included fearing judgemental questions from public providers and wanting more time before starting treatment. Clients shared concerns about kit accuracy and suggested that instructional materials be provided with more diverse language options. Conclusions: Web‐based HIVST services with tailored support appeared to facilitate HIV service access and engagement of harder‐to‐reach populations across India. Assistance from a community‐oriented counsellor proved important to overcome literacy barriers and mistrust in order to support the HIVST process and service linkage. Learnings can inform global efforts to improve the critical step of diagnosis in achieving epidemic control for HIV and other infectious diseases., INTRODUCTION Globally, infectious disease programmes have ambitious targets to achieve epidemic control or elimination. UNAIDS has established 95‐95‐95 targets for HIV wherein 95% of people living with HIV (PLHIV) are [...]

Haplotyping of human chromosomes is a prerequisite for cataloguing the full repertoire of genetic variation. We present a microfluidics-based, linked-read sequencing technology that can phase and haplotype germline and cancer genomes using nanograms of input DNA. This high-throughput platform prepares barcoded libraries for short-read sequencing and computationally reconstructs long-range haplotype and structural variant information. We generate haplotype blocks in a nuclear trio that are concordant with expected inheritance patterns and phase a set of structural variants. We also resolve the structure of the EML4-ALK gene fusion in the NCI-H2228 cancer cell line using phased exome sequencing. Finally, we assign genetic aberrations to specific megabase-scale haplotypes generated from whole-genome sequencing of a primary colorectal adenocarcinoma. This approach resolves haplotype information using up to 100 times less genomic DNA than some methods and enables the accurate detection of structural variants.

Dark resonating states render an important role in curtailing the dominant radiative losses in various photonic structures like metamaterials (MMs), photonic crystals, waveguides, etc. Currently, radiative losses are the major degrading factors toward the strong confinement of electromagnetic radiation for MMs' applications in sensing, imaging, filters, modulators, nonlinear studies, etc. Generally, the dark states cannot be excited through the direct interaction of electromagnetic radiations with the metastructures. However, indirect excitation at suitable structural asymmetries can trigger the evolution of dark resonating states or trapped modes. In this work, we have experimentally demonstrated mode hybridization of such dark (sub-radiant) resonating states without the direct involvement of interacting bright (super-radiant) states in a metasurface consisting of asymmetric split-ring resonators. Our study further reveals that the lattice mode plays a crucial role in determining the line shapes of the split (hybridized) modes. Such tuning of dark resonance modes can find potential applications in metasurfaces-based sensing, non-linear devices besides other potential applications desiring multi-channel strong field confinement.

Objective: To determine pattern of health care utilization and extent of out-of-pocket healthcare expenditure in rural areas of Punjab in India. Methods: Using multi stage sampling procedure, 660 participants were selected from 110 villages, out of all 22 districts; 440 participants had utilized outpatient care in past 15 days, and 220 had been hospitalized in past one year. Pretested semistructured questionnaires were used to enquire about household and healthcare expenditures. Out-of-pocket (OoP) expenditure included only direct costs of healthcare. Sevety seven 77 (12%) participants could not provide expenditures, hence were excluded from analysis. More than 10% of total household expenditure on healthcare was considered catastrophic. Results: Majority of the participants had used public sector health facilities for outpatient (57%) and inpatient (51.5%) care. Public sector facilities were utilized more often for communicable diseases and gynaecological problems whereas private sector services were used more commonly for accidents and non-communicable diseases. Mean healthcare expenditure on outpatient and inpatient healthcare services was Indian Rupees (INR) 8501 and INR 53889 respectively. Expenditure in private sector was significantly higher compared to the public sector facilities. Catastrophic expenditure was incurred by 7% of the households while seeking outpatient care and by 53% while seeking inpatient care. To pay for outpatient and inpatient care, 23.3% and 61.5% of the participants respectively had to borrow money or sell their assets. Conclusions: Healthcare expenditure places households under considerable financial strain in rural areas of Punjab in India. Improvements of public hospitals may increase their utilization and decrease financial burden. [ABSTRACT FROM AUTHOR]

This paper performs a secure communication by hiding an encoding message inside a video. The message is hided in a random frame and the stego frame and original frame are visually same. It means the technique is robust and it is very difficult to determine the stego frame within the video. Moreover, the message is encoded by using the DNA encoding. The DNA encoding uses the password based cipher message generated by using the DNA dictionary. The simulation results show the effectiveness of the technique. [ABSTRACT FROM AUTHOR]
