Exhaled breath test is a typical disease monitoring method for replacing of blood and urine samples that may create discomfort for patients. To monitor exhaled breath markers, gas biomedical sensors have undergone rapid progresses for non-invasive and point-of-care diagnostic devices. Among gas sensors, metal oxide-based biomedical gas sensors have received remarkable attentions owing to their unique properties, such as high sensitivity, simple fabrication, miniaturization, portability, and real-time monitoring. Herein, we reviewed the recent advances in chemoresistive metal oxide-based gas sensors with ZnO, SnO2, and In2O3 as sensing materials for monitoring a range of exhaled breath markers (i.e., NO, H2, H2S, acetone, isoprene, and formaldehyde). We focused on the strategies that improve the sensitivity and selectivity of metal oxide-based gas sensors. The challenges to fabricate a functional gas sensor with high sensing performance along with suggestions are outlined.The nutritional status at diagnosis, as well as weight loss during chemotherapy, are important factors for morbidity and mortality in cancer patients. They might also influence outcomes in patients with acute myeloid leukemia (AML) receiving allogeneic hematopoietic stem cell transplantation (HSCT). We evaluated the body mass index (BMI) at diagnosis, prior to HSCT, and the BMI difference (ΔBMI = BMIHSCT-BMIdiagnosis) in 662 AML patients undergoing allogeneic HSCT. Patients being obese at AML diagnosis had significantly higher nonrelapse mortality (NRM) and shorter overall survival (OS) after HSCT, but no distinct cumulative incidence of relapse than nonobese patients. Weight loss during chemotherapy (ΔBMI > -2) was a strong predictor for higher NRM and shorter OS in univariate and multivariate analyses. These results were observed across all European LeukemiaNet (ELN) 2017 risk groups but especially in patients with favorable or intermediate ELN2017 risk and patients transplanted in morphologic complete remission. Only in patients being obese at AML diagnosis, weight loss did not result in adverse outcomes. ΔBMI > -2 represents a strong, independent, and modifiable risk factor for AML patients treated with HSCT. Nutritional monitoring and supplementation during disease course might improve patients' outcomes.Background South Africa began offering medical male circumcision (MMC) in 2010. We evaluated the current and future impact of this program to see if it is effective in preventing new HIV infections. Methods The Thembisa, Goals and Epidemiological Modeling Software (EMOD) HIV transmission models were calibrated to South Africa's HIV epidemic, fitting to household survey data on HIV prevalence, risk behaviors, and proportions of men circumcised, and to programmatic data on intervention roll-out including program-reported MMCs over 2009-2017. We compared the actual program accomplishments through 2017 and program targets through 2021 with a counterfactual scenario of no MMC program. Results The MMC program averted 71,000-83,000 new HIV infections from 2010 to 2017. The future benefit of the circumcision already conducted will grow to 496,000-518,000 infections (6-7% of all new infections) by 2030. If program targets are met by 2021 the benefits will increase to 723,000-760,000 infections averted by 2030. The cost would be $1,070-1,220 per infection averted relative to no MMC. The savings from averted treatment needs would become larger than the costs of the MMC program around 2034-2039. In the Thembisa model, when modelling South Africa's 9 provinces individually, the 9-provinces-aggregate results were similar to those of the single national model. Across provinces, projected long-term impacts were largest in Free State, KwaZulu-Natal and Mpumalanga (23-27% reduction over 2017-2030), reflecting these provinces' greater MMC scale-up. Conclusions MMC has already had a modest impact on HIV incidence in South Africa and can substantially impact South Africa's HIV epidemic in the coming years.The COVID-19 pandemic has disrupted the already low resourced, fragmented and largely unregulated health systems in countries like India. It has only further exacerbated the stress on human resources for health (HRH) in many unanticipated ways. selleck inhibitor We explored the effect of COVID-19 pandemic on the health workforce in India, and analytically extrapolated the learnings to draw critical components to be addressed in the HRH policies, which can further be used to develop a detailed 'health workforce resilience' policy. We examined the existing literature and media reports published during the pandemic period, covering the gaps and challenges that impeded the performance of the health workers. Recommendations were designed by studying the learnings from various measures taken within India and in some other countries. We identified seven key areas that could be leveraged and improved for strengthening resilience among the health workforce. The system-level factors (at macro level) include developing a health workforce resilience policy, planning and funding for emergency preparedness, stakeholder engagement and incentivization mechanisms; the organization-level factors (meso level) include identifying HRH bench strength, mobilizing the health workforce, psycho-social support, protection from disease; and the individual-level factors (micro level) include measures around self-care by health workers. In keeping with the interdisciplinary nature of the associated factors, we emphasize on developing a future-ready health workforce using a multi-sectoral approach for building its strength and resilience.Pandemics are nothing unusual but indeed lead to devastating effects that play a pivotal role in reshaping human history. The COVID-19 outbreak is currently responsible for major educational crises globally as most of the world has been faced with a mandated lockdown, and forced closure of educational institutions, including medical colleges. Anatomists have therefore been challenged to unlock technology in effort to achieve best deliverables for their discipline, without the use of traditional teaching aids such as the cadaver, osteological banks, prosected specimens, models, and microscopic slides. At present, the virtual classroom is the only option for the anatomist, thereby omitting vital aspects of the hidden curriculum such as ethical-reasoning, empathy, respect, professionalism, interpersonal, and communication skills. As body donations dwindle, the era of teaching in a cadaverless environment is upon us. This marks the beginning of a paradigm shift in education and research for anatomists worldwide. Given the variable pathological-morphological presentation in COVID-19-related deaths, it is also likely that the autopsy component of anatomic pathology will be resuscitated to demystify the underlying mechanisms of the virus.
