BackgroundUnderstanding the perception and concerns of people about COVID-19 vaccine in developing and populous country like India will help in understanding demand for the vaccine and further tailoring out public health information and education activities before the launch of the vaccine. The study was carried out to assess the present state of knowledge people have about the probable vaccine for COVID-19, to know the preferences of respondents about this vaccine and to learn the expectations and apprehensions of people about features of this prospective COVID-19 vaccine residing in the capital city of India.MethodsThis cross-sectional study was conducted amongst the residents of Delhi, India from July-October 2020. Both offline and online interview method was used to collect date from 513 participants representing various occupational strata. Data was collected on socio demographic variable, vaccine acceptance and concerns regarding COVID-19 vaccine.ResultsAmong the study population 79.5% said they will take the vaccine while 8.8% said they were not going to take the vaccine and remaining 11.7% had not yet decided about it. Most of them(78.8%),believed that vaccine would be available to public next year but at the same time half(50.1%) of them believe that it may not be in sufficient amount for everyone to get. More than 50% were willing to pay for the vaccine and 72% felt vaccine should first be given to health workers and high risk group.ConclusionThe following study has helped to understand the percentage of people who are hesitant to take the vaccine and also the concerns regarding the vaccine. Also since half of the population is willing to pay for the vaccine, a strategical approach considering the various economical classes of people could be applied in a developing country like India.

Background: Understanding the perception and concerns of people about COVID-19 vaccine in developing and populous country like India will help in understanding demand for the vaccine and further tailoring out public health information and education activities.

More than 30 blood group systems have been recognized by International Society of Blood Transfusion (ISBT). ABO blood group is one of the most studied blood group system. ABO blood group system consist of three alleles A, B and O, out which A and B are co-dominant and O is recessive. Many researchers and investigators have found association between ABO blood group and cancer risk. It was found from the recent data that blood group A and AB is associated with increased pancreatic and gastric cancer risk. In the present study data of ABO blood group of 243 patients, both males and females, with confirmed cases of cancer was obtained from Sir Sunderlal hospital, Institute of Medical Science (IMS), Banaras Hindu University (BHU) and Apex hospital, DLW Road, Varanasi. 250 Samples of both males and females were taken as control. Out of 243 cancer patients 117 were males and 126 were females. In 243 cases enrolled in present study, highest number of cases were of breast cancer among women and lowest were rectal cancer. It was found that A blood group was associated with breast cancer, oral cancer, liver cancer and ovarian cancer as compared to other blood group and blood group O was associated with lung cancer, gastric cancer, colon cancer, skin cancer and endometrial cancer.

They are also associated with economic, social and psychological impacts that impinge on oral function, appearance, and social interactions, leading to the disruption of the daily routines. 3Quality of life is multidimensional and it is based mainly on the individual functional health status, level of pain, self-attribution, self-perception and quality of interaction ABSTRACT Background: The modern day oral oncotherapy is now concerned on the oral quality of life after treatment of the patient. There is need to evaluate final outcome following the different combination of treatment modalities available to make better therapeutic treatment decisions. Oral health-related quality of life (QHRQOL) and their nutritional status is gaining importance as a valuable outcome measure in oral cancer area and compare with the other control group. The aim of the study was to examine the nutritional status among the oral cancer patients and compare the QHRQoL of two groups (i.e., oral cancer group and control group) in Varanasi district. Methods: The prospective study was conducted from January 2018 to August 2018. 124 oral cancer patients and 124 control people from the Varanasi district participated in this study. Nutritional status of oral cancer treated patients was assessed. QHRQoL of the oral cancer patients were compared with the control group. Results: Among the 124 oral cancer patient, 67.74% were malnourished or at risk of malnutrition. Patients had worse QHRQoL among oral cancer group. There were highly statistically significant differences found in the oral health impact profile and oral impacts on daily performances on comparing the oral cancer patients with the control group. Conclusions: This study indicated that oral cancer patients with malnutrition or risk of malnutrition have significantly worse OHRQoL than with the control population group.

Introduction Healthcare workers (HCW) are most vulnerable to contracting COVID-19 infection. Understanding the extent of human-to-human transmission of the COVID-19 infection among HCWs is critical in managing this infection and for policy making. We did this study to estimate new infection by seroconversion among HCWs in recent contact with COVID-19 and predict the risk factors for infection. Methods A cohort study was conducted at a tertiary care COVID-19 hospital in New Delhi during the first and second waves of the COVID-19 pandemic. All HCWs working in the hospital during the study period who came in recent contact with the patients were our study population. The data was collected by a detailed face-to-face interview, serological assessment for anti- COVID-19 antibodies at baseline and end line, and daily symptoms. Potential risk factors for seroprevalence and seroconversion were analyzed by logistic regression keeping the significance at p<0.05. Results A total of 192 HCWs were recruited in this study, out of which 119 (62.0%) were seropositive. Almost all were wearing Personal protective equipment (PPE) and following Infection prevention and control (IPC) measures during their recent contact with a COVID-19 patient. Seroconversion was observed among 36.7% of HCWs, while 64.0% had a serial rise in the titer of antibodies during the follow-up period. Seropositivity was negatively associated with being a doctor (odds ratio [OR] 0.35, 95% Confidence Interval [CI] 0.18–0.71), having COVID-19 symptoms (OR 0.21, 95% CI 0.05–0.82), having comorbidities (OR 0.14, 95% CI 0.03–0.67), and received IPC training (OR 0.25, 95% CI 0.07–0.86), while positively associated with partial (OR 3.30, 95% CI 1.26–8.69), as well as complete vaccination for COVID-19 (OR 2.43, 95% CI 1.12–5.27). Seroconversion was positively associated with doctor as a profession (OR 13.04, 95% CI 3.39–50.25) and with partially (OR 4.35, 95% CI 1.07–17.65), as well as fully vaccinated for COVID-19 (OR 6.08, 95% CI 1.73–21.4). No significant association was observed between adherence to any IPC measures and PPE adopted by the HCW during the recent contact with COVID-19 patients and seroconversion. Conclusion Almost all the HCW practiced IPC measures in these settings. High seropositivity and seroconversion are most likely due to concurrent vaccination against COVID-19 rather than recent exposure to COVID-19 patients. Further studies using anti-N antibodies serology may help us find the reason for the seropositivity and seroconversion among HCWs.
