Emerging and Public Health Challenges Existing in Gestational Diabetes Mellitus and Diabetes in Pregnancy.

We review the evidence available worldwide on the various challenges in the screening, management, prevention of gestational diabetes mellitus and diabetes in pregnancy. The use of multiple screening and diagnostic tests prescribed by numerous guidelines is challenging for practitioners. Also, sociocultural, demographic and economic challenges affect the prevention and care. Life-course perspectives need to be adopted, as well as an integrated approach in public health care is essential. Tackling these challenges at each phase of life-course, with development and adherence to the country-specific guidelines by practitioners can decrease the burden of gestational diabetes mellitus and diabetes in pregnancy.

Second round statewide survey for estimation of the burden of active infection and anti-SARS-CoV-2 IgG antibodies in the general population of Karnataka, India

ObjectiveThe second round of the serial cross-sectional sentinel-based population survey to assess active infection, seroprevalence, and their evolution in the general population across Karnataka was conducted. Additionally, a longitudinal study among participants identified as COVID-19 positive in the first survey round was conducted to assess the clinical sensitivity of the testing kit used. MethodsThe cross-sectional study of 41,228 participants across 290 healthcare facilities in all 30 districts of Karnataka was done among three groups of participants (low, moderate, and high-risk). Consenting participants were subjected to real-time reverse transcription-polymerase chain reaction (RT-PCR) testing, and antibody (IgG) testing. ResultsOverall weighted adjusted seroprevalence of IgG was 15.6% (95% CI: 14.9-16.3), crude IgG prevalence was 15.0% and crude active prevalence was 0.5%. Statewide infection fatality rate (IFR) was estimated as 0.11%, and COVID-19 burden estimated between 26.1 to 37.7% (at 90% confidence). Clinical sensitivity of the IgG ELISA test kit was estimated as [≥]38.9%. ConclusionThe sentinel-based population survey helped identify districts that needed better testing, reporting, and clinical management. The state was far from attaining natural immunity during the survey and hence must step up vaccination coverage and enforce public health measures to prevent the spread of COVD-19.
