Introduction: Countries globally are evaluating the concept of herd immunity and its critical role in the control of pandemic. The current paper attempts to conduct a critical interpretative synthesis (CIS) on the role of herd immunity in current COVID-19 pandemic., Methods: CIS is tool for developing theoretical framework using interpretation drawn from relevant empirical and non-empirical sources. This review is done by formulating review question for literature search. Purposive sampling of literature was done followed by reciprocal translational analysis of extracted data., Results: Herd immunity is indirect protection from a contagious infectious disease when a population is immune either through vaccination or natural immunity developed through previous infection. The reproduction number for COVID-19 in India was found to be 2.56 and herd immunity threshold as 61%., Discussion: Exposing 71% young population in India to the SARS-CoV-2 infection can achieve herd immunity but with high morbidity as well as mortality. Vaccine are under process. Feco-oral transmission and reinfection of COVID 19 are major factors to develop or break the circle of herd immunity in community. "Immunity passport" can give false sense of security. Surveillance and seroprevalence studies assess immunity status, gradual exposure of infection to younger population and collaborative partnerships on organizations are few strategies to acquire herd immunity., Conclusion: Herd immunity is a measure for prevention and control of COVID-19 pandemic against the backdrop of mortality and morbidity. Vaccine can be boon but if herd immunity is to be acquired by natural infection then preparedness is necessary., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Journal of Family Medicine and Primary Care.)

COVID-19 pandemic has involved nations and incapacitated the health systems globally. The pandemic preparedness has been tested with immense losses. Universal health coverage is needed more than ever to recuperate from the effects of the current pandemic. Post pandemic, many lessons need to be learnt especially for developing economies like India where public healthcare system is grossly inadequate to take care of health needs of citizens. World Health Organization's framework of six health system building blocks was utilized to study the lessons learnt and actionable points in the post pandemic period. Participation in Global Health Security Alliance has to be stepped up with involvement in Joint external evaluation and development of epidemiological core capacities. National Health Security Action Plan needs to drafted and available for health emergences. Ayushman Bharat scheme should incorporate elements to address surge capacity at the time of health emergencies and measures to deliver care at the time of pandemic. Technology through telemedicine, m-health, and digital platforms or apps should contribute to trainings, supervision, and facilitation of healthcare delivery at remote locations. Open data sharing policies should be developed for the practice of evidence-based public health. Public healthcare system and health manpower trained in epidemiology should be given a boost to have system readiness to respond in case of future pandemics., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Journal of Family Medicine and Primary Care.)

Telemedicine and related e-health facilities facilitate care from a distance through electronic information systems. COVID-19 pandemic is establishing telemedicine in the health care delivery system of countries. Telehealth is contributing significantly in health care delivery during the COVID-19 crisis. For mild-to-moderate symptoms of COVID-19 or any illness, telehealth services might represent a better, efficient way to receive initial care and perform triaging. Telemedicine also has a significant role in screening for COVID-19 symptoms and delivering routine needs and follow-up care. The large-scale adoption of telemedicine in public health care delivery is still not visible in low- and middle-income countries like India. Adoption by patients and healthcare professionals is limited and their concerns need to be addressed to ensure its utilization in future of the care continuum. In the current paper, we aim to review recent measures of Telemedicine adopted during the course of pandemic and its impact on public health in lower-middle income countries like India., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Journal of Family Medicine and Primary Care.)

Aim: To evaluate the scouting ability of three pathfinding nickel-titanium rotary instruments in moderately curved molar canals., Materials and Methods: Ninety maxillary and mandibular molars were collected and were divided randomly into three groups each having 15 maxillary and 15 mandibular molars. The teeth were mounted on a specific apparatus for simulation of dento-alveolar socket. After access cavity preparation, the canals were negotiated with 08 K-file. Glide path preparation was performed using Mtwo or ProGlider or OneG instruments. The number of teeth in which the file reached the full working length (RFWL), number of passes required, and number of fractured instruments were recorded and subjected to statistical analysis using Chi-square, Kruskal-Wallis, and Mann-Whitney tests., Results: There was a significant difference between the groups ( P < 0.05). The RFWL of ProGlider was significantly higher than that of Mtwo ( P = 0.005) and OneG ( P = 0.037). The percentage of fracture with ProGlider was 6.67% and both Mtwo and OneG had 26.67% frequency. The difference was not statistically significant ( P > 0.05). There was significant difference in the number of insertion passes in maxillary distobuccal ( P < 0.05), mandibular mesiobuccal ( P < 0.01), and distal ( P < 0.01) canals. ProGlider was the most effective pathfinding instrument due to its file's design and a progressive taper of 2%-8%. This achieves a greater preflaring of the coronal and middle portions of the root canal, rendering the advance of the instrument toward the apex easier., Conclusion: ProGlider performed more efficiently and with less instrument breakage in scouting moderately curved canals of molar teeth., Competing Interests: There are no conflicts of interest.

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., Competing Interests: There are no conflicts of interest.

Introduction: Chronic non communicable diseases in India have increased in magnitude with earlier onset and more likelihood of complications. Much emphasis is given to early diagnosis and timely treatment. Additionally, tertiary prevention through medication adherence is needed to limit disability and prevent early onset of complications. This study was aimed to assess the magnitude of medication and lifestyle adherence among elderly patients suffering from diabetes and hypertension in rural areas of Punjab., Methodology: This was a clinic based study in district Fatehgarh Sahib, Punjab. Patients were subjected to regular blood pressure and blood glucose monitoring. Thereafter they were offered free medications through weekly clinic held at Community Health Center, Bassi Pathana. Along with treatment, Public Health Nurse conducted counselling on diet and lifestyle. Frequency and process of taking medications was explained in local language and records duly maintained during visits., Results: Nearly 70% of study subjects were more than 50 years old. Males constituted 26% of the sample and 60% of subjects were illiterate. Large majority of study subjects did not consumed tobacco (98.08%) or alcohol (89.42%) in past thirty days. In-sufficient physical activity and poor compliance to diet was reported by 10.5% (Males: 7.4%, Females: 11.7%) and 23.5% (Males: 31.5%, Females: 20.8%) subjects. Nearly 46.15% of study subjects reported missing prescribed medications. Nearly 61.54% of study subjects were very sure that they will be able to take medicines as directed by physician., Conclusion: National Program for Control of Diabetes, Cardio-vascular Disease and Stroke relies on early diagnosis and treatment non- communicable diseases. However, with reported levels of adherence to medication and lifestyle interventions, there is an urgent need of exploring innovative ways to ensure compliance and improve treatment outcomes., Competing Interests: There are no conflicts of interest.

Background: Use of blood and its components is lifesaving. However, their use is often associated with adverse events., Objective: To analyze the pattern of adverse reactions associated with transfusion of blood and its components in pediatric and surgical patients at a tertiary care teaching hospital., Materials and Methods: Patients receiving transfusion of blood or its components in a randomly selected unit each from Departments of Pediatrics, including thalassemia OPD and surgery, were monitored intensively for a period of 6 months. Clinical course, management, outcome, causality, severity, seriousness, and preventability of observed transfusion reactions (TRs) were analyzed., Results: A total of 411 pediatric and 433 surgical patients received 594 and 745 transfusions respectively during the study period. Of these, TRs were observed in 69 (11.6%) children and 63 (8.4%) surgical patients. Majority of reactions in children (48, 69.5%) and surgical patients (51, 80.9%) were acute, developing within 24 h of transfusion. TRs were observed with packed cells (13.2%), cryoprecipitate (10%), platelet concentrate (14.3%) and fresh frozen plasma (1.3%) in pediatric patients and with packed cells (7.2%), whole blood (25%) and platelet concentrate (62.5%) in surgical patients. Most common TRs included febrile nonhemolytic TRs (FNHTRs) and allergic reactions. Reactions were more frequent in patients with a previous history of transfusion or those receiving more than one transfusion and in children, when transfusion was initiated after 30 min of issue of blood component. Majority of reactions were managed with symptomatic treatment, were nonserious, moderately severe, probably preventable and probably associated with the suspect blood component in both populations., Conclusion: Transfusion reactions in children and surgical patients are commonly observed with cellular blood components. Majority of reactions are acute and nonserious. FNHTRs and allergic reactions are the most common transfusion reactions. Risk of transfusion reactions is more in patients receiving multiple transfusions., Competing Interests: There are no conflicts of interest.

Iodine deficiency disorders (IDDs) have been recognized as one of the major nutritional disorders throughout the world affecting 200 million people who are at risk and another 71 million suffering from goiter and other IDDs. These groups of disorders can affect every stage of life, but most vulnerable age group is between 6 and 12 years and these disorders together constitute the single largest preventable cause of brain damage leading to learning disabilities and psychomotor impairment. The existence of endemic goiter in an extensive belt along the southern slopes of the Himalayas, Alps, and Andes has long been described, but consistently high prevalence of IDDs outside the endemic zones and failure to attain goals set by the National Iodine Deficiency Disorder Control Program questions the strategy and achievements till date. Therefore, the present article is an attempt to critically examine the program since inception in India., Competing Interests: There are no conflicts of interest.

Background and Objective: Therapeutic Plasma Exchange (TPE) is performed effectively and safely in adult patients, but the use of TPE is limited in paediatric patients due to lack of universally accepted indications and technical challenges like establishment of adequate vascular access, low blood volume, increased incidence of adverse events during procedure and poor co-operation of patients during procedure. We present our experience of TPE in paediatric patients to assess the effectiveness and safety of TPE in paediatric patients., Materials and Methods: A total 122 TPE procedures were performed in 40 paediatric patients between 3 to 15 years of age group with Guillain Barre Syndrome (GBS). TPE procedures were performed on alternate days depending on the clinical condition of the patient. Patient's total blood volume was calculated as per Nadler's formula and processed through central double lumen catheter. 1-1.5 plasma volume was exchanged with normal saline and fresh frozen plasma., Results: A total of 122 TPE procedures (with an average of three procedures per patient) were performed on 40 paediatric patients. More than three TPE procedures were performed in 29 patients, of which 27 patients showed improvement from grade-0 and grade-I to grade-III. One did not show any response and succumbed to the disease. Complications were observed in 14 patients which were well managed. Inadequate vascular access was most common complication observed in 11 patients., Conclusion: TPE in paediatric patients has been increasing and has been shown to be effective as first line or adjunctive therapy in selected diseases. It is safe procedure when volume shifts, calcium supplementation and venous access are taken care.

Introduction: Partial phenotyping of voluntary blood donors has vital role in transfusion practice, population genetic study and in resolving legal issues. The Rh blood group is one of the most complex and highly immunogenic blood group known in humans. The Kell system, discovered in 1946, is the third most potent system at triggering hemolytic transfusion reactions and consists of 25 highly immunogenic antigens. Knowledge of Rh & Kell phenotypes in given population is relevant for better planning and management of blood bank; the main goal is to find compatible blood for patients needing multiple blood transfusions. The aim of this study was to evaluate the frequency of Rh & Kell phenotype of voluntary donors in Gujarat state., Materials and Methods: The present study was conducted by taking 5670 samples from random voluntary blood donors coming in blood donation camp. Written consent was taken for donor phenotyping. The antigen typing of donors was performed by Qwalys-3(manufacturer: Diagast) by using electromagnetic technology on Duolys plates., Results: Out of 5670 donors, the most common Rh antigen observed in the study population was e (99.07%) followed by D (95.40%), C (88.77%), c (55.89%) and E (17.88%). The frequency of the Kell antigen (K) was 1.78 %., Discussion: The antigen frequencies among blood donors from Gujarat were compared with those published for other Indian populations. The frequency of D antigen in our study (95.4%) and north Indian donors (93.6) was significantly higher than in the Caucasians (85%) and lower than in the Chinese (99%). The frequencies of C, c and E antigens were dissimilar to other ethnic groups while the 'e' antigen was present in high frequency in our study as also in the other ethnic groups. Kell antigen (K) was found in only 101 (1.78 %) donors out of 5670. Frequency of Kell antigen in Caucasian and Black populations is 9% & 2% respectively. The most common Kell phenotype was K-k+, not just in Indians (96.5%) but also in Caucasians (91%), Blacks (98%) and Chinese (100%)., Conclusion: Phenotype and probable genotype showed wide range of variations in different races and religion. Reliable population based frequency data of Rh & Kell antigens has vital role in population genetic study, in resolving medico legal issues and in transfusion practice.

Background & Objectives: India is a large country with each State having distinct social, cultural and economic characteristics. Tobacco epidemic is not uniform across the country. There are wide variations in tobacco consumption across age, sex, regions and socio-economic classes. This study was conducted to understand the wide inequalities in patterns of smoking and smokeless tobacco consumption across various States of India., Methods: Analysis was conducted on Global Adult Tobacco Survey, India (2009-2010) data. Prevalence of both forms of tobacco use and its association with socio-economic determinants was assessed across States and Union Territories of India. Wealth indices were calculated using socio-economic data of the survey. Concentration index of inequality and one way ANOVA assessed economic inequality in tobacco consumption and variation of tobacco consumption across quintiles. Multiple logistic regression was done for tobacco consumption and wealth index adjusting for age, sex, area, education and occupation., Results: Overall prevalence of smoking and smokeless tobacco consumption was 13.9 per cent (14.6, 13.3) and 25.8 per cent (26.6, 25.0), respectively. Prevalence of current smoking varied from 1.6 per cent (richest quintile in Odisha) to 42.2 per cent (poorest quintile in Meghalaya). Prevalence of current smokeless tobacco consumption varied from 1.7 per cent (richest quintile in Jammu and Kashmir) to 59.4 per cent (poorest quintile in Mizoram). Decreasing odds of tobacco consumption with increasing wealth was observed in most of the States. Reverse trend of tobacco consumption was observed in Nagaland. Significant difference in odds of smoking and smokeless tobacco consumption with wealth quintiles was observed. Concentration index of inequality was significant for smoking tobacco -0.7 (-0.62 to-0.78) and not significant for smokeless tobacco consumption -0.15 (0.01 to-0.33) INTERPRETATION & CONCLUSIONS: The findings of our analysis indicate that tobacco control policy and public health interventions need to consider widespread socio-economic inequities in tobacco consumption across the States in India.

Background: Adolescents are a heterogeneous, vulnerable, and sexually active group. Geographical and educational health disparities exist among urban, rural, and slum adolescents and among out-of-school and school-going adolescents, respectively. Adolescent reproductive and sexual health (ARSH) services should be implemented in a manner to minimize health inequities among them., Objectives: To ascertain the extent of awareness and utilization of ARSH services provided under reproductive and child health(RCH) program among adolescents in Chandigarh., Materials and Methods: A cross-sectional study was conducted among 854 adolescents (402 household, 200 out-of-school, and 252 school-going adolescents) in Chandigarh using pretested validated interview schedule on awareness and utilization of adolescent reproductive and sexual health services from February to April 2011 in North Indian Union Territory of Chandigarh. Ordinal regression analysis was done to study the association of socio-demographic variables with awareness and utilization of ARSH. Results: Awareness about contraception and health services was significantly less among rural (12.7% and 1.1%, respectively) adolescents as compared to slum (17.9% and 4.6%, respectively) and urban adolescents (33.5% and 7.8%, respectively) (P < 0.05). Out-of-school adolescents were utilizing the preventive [odds ratio (OR) 0.39, P < 0.001] and curative services significantly lesser (OR = 0.54, P < 0.001) and had higher substance abuse (OR = 4.26, P= 0.006). Awareness was significantly associated with older age of adolescents (OR = 4.4,P < 0.001), poor education of father (OR = 0.5, P = 0.002), rural area (OR = 0.56, P = 0.001), and out-of-school status (OR = 0.35, P < 0.001)., Conclusion: Awareness and utilization of ARSH services was inequitable and was more among urban and school-going adolescents. Educational status was the most important factor affecting it.
