Biochemical composition, transmission and diagnosis of SARS-CoV-2.

Coronavirus disease 2019 (COVID-19) is a life-threatening respiratory infection caused by severe acute respiratory syndrome virus (SARS-CoV-2), a novel human coronavirus. COVID-19 was declared a pandemic by World Health Organization in March 2020 for its continuous and rapid spread worldwide. Rapidly emerging COVID-19 epicenters and mutants of concerns have created mammoth chaos in healthcare sectors across the globe. With over 185 million infections and approximately 4 million deaths globally, COVID-19 continues its unchecked spread despite all mitigation measures. Until effective and affordable antiretroviral drugs are made available and the population at large is vaccinated, timely diagnosis of the infection and adoption of COVID-appropriate behavior remains major tool available to curtail the still escalating COVID-19 pandemic. This review provides an updated overview of various techniques of COVID-19 testing in human samples and also discusses, in brief, the biochemical composition and mode of transmission of the SARS-CoV-2. Technological advancement in various molecular, serological and immunological techniques including mainly the reverse-transcription polymerase chain reaction (RT-PCR), CRISPR, lateral flow assays (LFAs), and immunosensors are reviewed.

Need of Palliative Care Services in Rural Area of Northern India.

BACKGROUND: Palliative care is comprehensive care that provides symptomatic relief and enhances the quality of life for people experiencing serious health-related suffering. There is an increasing need for palliative care services in India. Estimates for population requiring these services are essential in order to meet the increasing need for palliative care services. OBJECTIVES: The objective was to assess the proportion of population requiring and receiving palliative care services. MATERIALS AND METHODS: A descriptive cross-sectional research design was adopted for the study. The study was carried out in the village, Dhanas, Chandigarh. All the residents residing in the selected rural area were included in the study. Tools used for data collection were a screening questionnaire consisting of three questions, a sociodemographic sheet, a clinical profile, the Barthel Index of activities of daily living (ADL), and a pain rating scale. Analysis of the data was done using SPSS version 19 (IBM SPSS Statistics for Windows, Version 19.0.: IBM Corp). RESULTS: A total of 10,021 people from 884 households were screened in the study. The results revealed that the prevalence of need for palliative care services was 2/1000 population. None of the 19 participants with unmet palliative care needs were receiving any home- or institutional-based palliative care services at the time of assessment. Nearly, one-fourth of the participants had total dependency on caregivers for ADL. CONCLUSION: The study concluded that there is a need of palliative care services in the studied rural community of Chandigarh. These data can be used for planning and implementing community-based palliative care services in the studied area.

The Therapeutic and Preventive Efficacy of Curcumin and Its Derivatives in Esophageal Cancer

Esophageal cancer is the eighth most common occurring cancer type worldwide and 6th most common among the cancer related deaths of which the most common type is squamous cell carcinoma which comprise about 90% of esophageal cancer cases. The standard of care for esophageal cancer is neoadjuvant concurrent chemotherapy and radiation (NACRT) followed by surgery however the prognosis remains dismal with 5 year survival a meager 10-15%. The treatment modalities for esophageal cancer is associated with both long term and short term toxicities. Curcumin has been explored as a therapeutic modality as a chemo adjuvant in different cancers due to its low toxicity profile and potent anticancer effect however despite lot of promising preclinical data it has not progressed from bench side to bed side. The primary reason that has obstructed its application in clinic has been its low bioavailability which was seen in different clinical trials but there has been tremendous progress in developing formulations of curcumin which have significantly increased its bioavailability and are being tested in clinical trials. Esophageal cancer is associated with inflammation that's why curcumin being a natural antioxidant offer a potential avenue to reduce toxicity of current therapeutic modalities in a chemo adjuvant setting while simultaneously targeting different pro oncogenic pathways. The present review tries to cover in depth different aspects of curcumin application in treatment of esophageal cancer and progress of this potent anticancer agent in its treatment and prevention.
