Vaccination coverage and breakthrough infections of COVID-19 during the second wave among staff of selected medical institutions in India.

India experienced the second wave of SARS-CoV-2 infection from April 3 to June 10, 2021. During the second wave, Delta variant B.1617.2 emerged as the predominant strain, spiking cases from 12.5 million to 29.3 million (cumulative) by the end of the surge in India. Vaccines against COVID-19 are a potent tool to control and end the pandemic in addition to other control measures. India rolled out its vaccination programme on January 16, 2021, initially with two vaccines that were given emergency authorization-Covaxin (BBV152) and Covishield (ChAdOx1 nCoV- 19). Vaccination was initially started for the elderly (60+) and front-line workers and then gradually opened to different age groups. The second wave hit when vaccination was picking up pace in India. There were instances of vaccinated people (fully and partially) getting infected, and reinfections were also reported. We undertook a survey of staff (front line health care workers and supporting) of 15 medical colleges and research institutes across India to assess the vaccination coverage, incidence of breakthrough infections, and reinfections among them from June 2 to July 10, 2021. A total of 1876 staff participated, and 1484 forms were selected for analysis after removing duplicates and erroneous entries (n = 392). We found that among the respondents at the time of response, 17.6% were unvaccinated, 19.8% were partially vaccinated (received the first dose), and 62.5% were fully vaccinated (received both doses). Incidence of breakthrough infections was 8.7% among the 801 individuals (70/801) tested at least 14 days after the 2nd dose of vaccine. Eight participants reported reinfection in the overall infected group and reinfection incidence rate was 5.1%. Out of (N = 349) infected individuals 243 (69.6%) were unvaccinated and 106 (30.3%) were vaccinated. Our findings reveal the protective effect of vaccination and its role as an essential tool in the struggle against this pandemic.

A case report of late treatment failure in Plasmodium falciparum malaria in a traveler from the Democratic Republic of the Congo to India.

A young male returned from the Democratic Republic of the Congo (DRC) to India after four months during his official work. Within a week of his arrival, he developed a high-grade fever with nausea and was hospitalized in a private hospital in New Delhi. He was diagnosed with malaria, treated with an artesunate injection as antimalarial, and discharged on day 5th from the hospital. A week later, he was diagnosed with malaria and dengue positive at ICMR-National Institute of Malaria Research, New Delhi. Artesunate with sulphadoxine and pyrimethamine (AS+SP) was administered following India's malaria treatment policy. However, high-grade fever, along with the asexual stage of the P. falciparum parasite, was observed within 28 days of treatment with AS+SP, signifying late treatment failure (LTF). Further, the molecular analysis from both the days of episodes was analyzed using genomic DNA from dried blood spots, revealing resistance to sulphadoxine-pyrimethamine with mutations at codons pfdhfr 51I, pfdhfr 59 R, pfdhfr 108 N, pfdhps 437 A, pfdhps 581 G. No functional mutation associated was found in pfKelch13, but interestingly the sensitive codons to chloroquine (CQ) (wild type pfcrtK76 and pfmdrN86) revealed the probably reversible CQ sensitivity in the sample from DRC.

Is the rule of halves in hypertension valid uniformly across India? A cross-sectional analysis of national family health survey-4 data.

Background: Hypertension is widely prevalent across India. The rule of halves is commonly used to describe the attrition and gaps in the care cascade of hypertension management across detection, availing treatment, and having controlled blood pressure (BP) on treatment. Objectives: Using nationally representative data, we aimed to assess the rule of halves in hypertension management in different states of India and across sociodemographic, health system, and personal factors. Methods: A descriptive analysis of secondary data from the National Family Health Survey-4 was conducted. We included 770,662 individuals (112,122 men and 658,540 nonpregnant women) of 15-49 years of age. The proportion of individuals not aware of hypertension status among those with high BP, known hypertensives not availing of treatment, and uncontrolled BP among those on treatment were expressed as percentage with a 95% confidence interval (CI). Results: Of those with high BP, 48.5% (95% CI: 47.8%-49.3%) were not aware of their hypertensive status. Among known hypertensives, 72% (95% CI: 71.2%-72.8%) had not availed treatment for hypertension. Among those on treatment, 39.8% (95% CI: 38.7%-40.9%) had uncontrolled hypertension. Conclusion: The rule of halves of India shows that the National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases, and Stroke has made relatively good progress with the detection of hypertension and achieving BP control among those on treatment. However, with three-fourth of known hypertensives not availing treatment, more dividends from the detection of hypertension efforts could be realized. The program needs to especially focus on ensuring the treatment for those detected with hypertension.

India may need an additional metric to assess the endemicity of malaria in low surveillance districts.

India's National Framework for malaria elimination is essentially dependent on Annual Parasite Incidence (API). API is the primary criterion for classifying states and districts into different categories: intensified control, pre-elimination, elimination, prevention and re-establishment of malaria. However, API's validity is critically dependent on multiple factors, one such important factor is Annual Blood Examination Rate (ABER) and is often considered as indicator of operational efficiency. Therefore, the present study aimed to determine whether the API is a sufficiently good malaria index to assess malaria endemicity in India. An in-depth analysis of malaria data (2017-19) was done to determine the appropriateness of API as a sole indicator of malaria endemicity. We stratified the Indian districts into three strata based on Annual Blood Examination Rate (ABER): <5, 5.0-5.0, >15, further APIs was compared with Slide Positivity Rates (SPRs) using sign rank test, independently in each stratum. API and SPR were found comparable (p-value 0.323) in stratum 2 only. However, in the case of lower ABER (<5%, strata 1), the API was significantly lower than the SPR, and higher ABER (>15%), the API was found substantially higher than the SPR. Thus, ABER tunes the validity of API and should avoid to use as a single indicator of malaria endemicity. API is an appropriate measure of malaria endemicity in high and moderate transmission areas where surveillance is good (ABER≥5%). However, it is vitally dependent upon surveillance rate and other factors such as population size, the selection of individuals for malaria testing. Therefore, where surveillance is poor (<5%), we propose that API should be complemented with SPR and the number of cases. It will significantly aid the design and deployment of interventions in India.

An investigation of the efficacy of different statistical models in malaria forecasting in the semi-arid regions of Gujarat, India.

BACKGROUND & OBJECTIVES: Robust forecasting of malaria cases is desirable as we are approaching towards malaria elimination in India. Methods enabling robust forecasting and timely case detection in unstable transmission areas are the need of the hour. METHODS: Forecasting efficacy of the eight most prominent statistical models that are based on three statistical methods: Generalized linear model (Model A and Model B), Smoothing method (Model C), and SARIMA (Model D to model H) were compared using last twelve years (2008-19) monthly malaria data of two districts (Kheda and Anand) of Gujarat state of India. RESULTS: The SARIMA Model F was found the most appropriate when forecasted for 2017 and 2018 using model-building data sets 1 and 2, respectively, for both the districts: Kheda and Anand. Model H followed by model C were the two models found appropriate in terms of point estimates for 2019. Still, we regretted these two because confidence intervals from these models are wider that they do not have any forecasting utility. Model F is the third one in terms of point prediction but gives a relatively better confidence interval. Therefore, model F was considered the most appropriate for the year 2019 for both districts. INTERPRETATION & CONCLUSION: Model F was found relatively more appropriate than others and can be used to forecast malaria cases in both districts.

Prevalence and predictors of exclusive breastfeeding in urban slums, Bihar.

OBJECTIVE: Various socio-cultural factors influence infant feeding practices and thus early childhood nutrition and child survival in India. This study aimed to examine the prevalence of exclusive breastfeeding, its promoters and barriers in urban slums of Bihar, India. METHODS: We conducted a community based cross-sectional survey involving 297 mothers living in slum settlements in Bihar. Data were collected using structured questionnaire on exclusive breastfeeding practices, and the factors that could influence this. Descriptive analysis was done to estimate the prevalence of exclusive breastfeeding and regression model was performed to identify the predictors of exclusive breastfeeding. RESULTS: Only 23% of mothers initiate breastfeeding within 1 hour of delivery and 27.6% mothers practise exclusive breastfeeding up to six months. Mother's education was found to be associated with duration of exclusive breastfeeding (OR 11, 95% CI 2-59). Term babies were more likely to be breastfed exclusively for six months than pre-term babies (OR 8.6, 95% CI 1.6-47.6). Antenatal care visits and completing immunization were significantly associated with duration of exclusive breastfeeding (P < 0.001). The majority of mothers acquire exclusive breastfeeding knowledge through television/radio (OR 68, 95% CI 5.5-832.5) and newspaper advertisements (OR 14, 95% CI 2.6-76). CONCLUSION: Prevalence of exclusive breastfeeding up to six months of age and early initiation of breastfeeding remains low in slums of Bihar. Exclusive breastfeeding and early initiation of breastfeeding rates could be improved by educating and counselling mothers during health facility contacts by primary care providers.

Cutaneous adverse effects due to personal protective measures during COVID-19 pandemic: a study of 101 patients.

BACKGROUND: Coronavirus Disease 2019 (COVID-19) is a viral illness caused by the novel coronavirus SARS-CoV-2 which spreads via droplets from an infected person. There has been an unprecedented rise in the use of personal protective equipment and practice of personal hygiene measures against COVID-19. The extended use of protective measures (PM) can lead to ill effects on the skin. Our aim was to investigate PM-induced dermatoses amongst healthcare workers and the general population during the COVID-19 pandemic. METHODS: A cross-sectional study was conducted over a period of 2 months. The study subjects were patients who presented to dermatology outpatient clinics or sought teleconsultation for skin problems related to the use of PMs against COVID-19. A detailed history was obtained and cutaneous examination was documented for all the patients in a pre-set proforma. Diagnoses of the adverse skin effects were formulated based upon history and clinical examination. RESULTS: A total of 101 cases with cutaneous adverse effects due to the use of PMs against COVID-19 were included in the study. The general population and healthcare workers were affected similarly, comprising of 54.5% and 45.5%, respectively. The mean age of the study participants was 36.71 ± 15.72 years. The most common culprit material was soap and water (56.4%). Contact dermatitis was found to be the most common adverse effect in the majority of our patients (72.3%). The most common symptom reported was pruritus (45.5%). The wearing of personal protective equipment for a longer duration was significantly associated with multiple symptoms (P = 0.026). CONCLUSION: The enhanced use of different PMs against COVID-19 can result in a variety of adverse skin effects. In our study, the use of soap and water was the most common culprit PM, and contact dermatitis was the most common adverse effect noted.

Profile of Defaulters and Pattern of Treatment Default among Leprosy Patients at a Tertiary Care Hospital: A 10-Year Analysis.

BACKGROUND: The focus of leprosy control programs worldwide today is the WHO multidrug therapy which adequately cures the disease. Incomplete treatment puts not only the patient but the entire community at risk which may further jeopardize the leprosy control program. OBJECTIVE: To study the magnitude of treatment default among leprosy patients, its trend in the last 10 years, and association with clinicodemographic variables. MATERIALS AND METHODS: This was a retrospective study conducted at the urban leprosy center (ULC) attached to the dermatology department of a tertiary care centre. Data were obtained from the standard leprosy cards maintained at ULC from 2005-14. The following data were collected from the preformatted cards: age, gender, residence, occupation, type of leprosy, treatment, time of default, and so on and analyzed to see the association of defaulter status with sociodemographic and disease-related variables. RESULTS: In a total of 743 cases, the rate of treatment default was 39.3%. The default status was found to have decreased significantly over the years from 2005-14 (P = 0.03). Majority of the treatment defaulters were migrants (47.9%) as compared with natives (29.7%) (P < 0.001). Regardless of the residential status, treatment default was more in pure neuritic (58.5%) and tuberculoid type (40.7%) as compared with others (P < 0.001). Smear negative cases (40.0%) were more likely to default than smear-positive cases (31.4%) (P < 0.001). Rate of defaulting was more among patients in the district where ULC was located than in the districts away from ULC (P = 0.017). CONCLUSION: Though the study period witnessed an overall decreasing trend over the 10-year period, treatment default remains a major concern in leprosy. Adherence to treatment is central to the success of leprosy control programs and therefore the factors associated with defaulting from treatment need to be addressed.

Cardiovascular and Metabolic Risk Assessment in Patients with Lichen Planus: A Tertiary Care Hospital-based Study from Northern India.

BACKGROUND: The association between lichen planus (LP) and cardiovascular disease (CVD) risk factors has been demonstrated in previous reports. However, the evidence of CVD risk factors in Indian patients with LP is limited. OBJECTIVE: To compare CVD risk factors in LP patients and healthy controls. METHODS: We performed a cross-sectional study on 122 subjects, 61 LP patients, and 61 controls who visited the outpatient clinic of the dermatology department of a tertiary care hospital. Patients with skin diseases known to be associated with CV risk, pregnant, and lactating women were excluded from the study. CVD risk factors were compared between LP cases and controls using anthropometric measures, hemodynamic and metabolic parameters, and inflammatory marker (ESR). RESULTS: The proportion of metabolic syndrome (MS) was significantly higher in LP patients than the controls (29.5% vs. 9.8%, odds ratio [OR] 3.83; 95% confidence interval [CI] 1.40-10.50; P = 0.006). The proportion of dyslipidemia was also significantly higher in LP patients (70.5% vs. 42.6%; P = 0.002). LP patients had a high proportion of obesity (P = 0.004), hypertension (P = 0.004), impaired fasting glucose (P = 0.025), and raised ESR (P = 0.006) as compared to controls. A multivariate regression model demonstrated that dyslipidemia and obesity were significantly associated with LP even after controlling for confounders such as age, gender, sedentarism, dietary habits, alcohol, and impaired fasting glucose. There was no significant association between the extent of LP and the proportion of MS or dyslipidemia. CONCLUSION: The present study found a significant association of LP with individual CVD risk factors as well as MS.

Trends and patterns of leprosy over a decade in a tertiary care hospital in Northern India: A retrospective analysis.

BACKGROUND: Leprosy was declared to be eliminated from India in 2006, but recent reports point to an increase in newly detected cases despite the overall fall in prevalence. AIM: This study aimed to analyze the patterns and trends of epidemiological and operational indicators of leprosy at a tertiary care center in northern India over a decade. METHODS: This is a 10-year retrospective study from 2005 to 2014 conducted at the urban leprosy centre (ULC) of the Department of Dermatology, Venereology, and Leprology, Government Medical College, Jammu (J and K), India. Data were obtained from the preformatted standard leprosy cards of the urban leprosy centre. Details of demographic data, clinical features, smear results and treatment received were collected from individual cards and analyzed to observe various epidemiological trends. RESULTS: A total of 743 cases were analyzed for the period 2005-2014, of which 8.6% were childhood cases, 52.5% patients were immigrants, and 56.4% were farmers and laborers. Lepromatous cases showed a significantly increasing trend when compared with tuberculoid cases (P < 0.05). Smear positivity was seen in 29.6% of cases and showed an increasing trend (P < 0.05). An important observation was the increase in multibacillary cases. World Health Organization (WHO) grade 2 disability also showed an increasing trend over the past decade pointing to delayed diagnosis. LIMITATION: The study is limited by its retrospective design. CONCLUSION: The increasing trend of lepromatous and multibacillary cases and cases with grade 2 disability is a poor sign as it indicates delays in diagnosis. Further, smear-positive cases contribute to continued transmission of disease in the community. Leprosy has been declared to be eliminated, but recent reports including the present study suggest a rise in newly detected cases and hence in disease burden.

Impact on quality of life in patients with dermatophytosis.

BACKGROUND/OBJECTIVES: Dermatophytosis can have a significant effect on patient's psychosocial and economic life. Despite this, knowledge on the quality of life (QoL) in patients with dermatophytosis is limited. The objective of the present study was to assess the quality of life in patients with dermatophytosis. METHODS: This was a cross-sectional study conducted in the Department of Dermatology at a tertiary care hospital from August 2018 to December 2018. All the patients with dermatophytosis aged ≥16 years were included and evaluated for impact on quality of life. The association of Dermatology Life Quality Index (DLQI) scores with disease characteristics was assessed using t-test, ANOVA and Pearson's correlation test, as applicable. RESULTS: A total of 348 patients were analysed. The mean ± SD DLQI score in our study was 13.4 ± 7.3. Dermatophytosis was found to have a very large effect on the QoL in majority (44.8%) of our patients. DLQI questions pertaining to symptoms and feelings and daily activity had the highest impact on patients. The DLQI score was significantly affected by the number of sites involved (P < 0.001), body surface area (P < 0.001) and the severity of symptoms (P = 0.007). CONCLUSION: Dermatophytosis was found to have a significant impact on the QoL of affected patients. The DLQI score was influenced by the severity of the disease. This study also underscores the feasibility of DLQI score based QoL assessment in dermatophytosis.

World Health Organization Dimensions of Adherence to Antiretroviral Therapy: A Study at Antiretroviral Therapy Centre, Aligarh.

INTRODUCTION: With the availability of antiretroviral therapy (ART) and subsequent change in the HIV/AIDS disease dynamic to a chronic manageable disease, adherence studies have received increasing attention. However, there is a paucity of studies that have considered World Health Organization (WHO) dimensions of adherence to ART. Therefore, this study was conducted with the objectives of determining the prevalence of adherence and the association of various factors across five WHO dimensions to adherence. METHODS: A cross-sectional study was carried out at the ART Centre, Aligarh. A total of 440 adult patients, taking treatment from the ART Centre, Aligarh were selected. A self-reported instrument of missing pills was used to measure adherence. Various factors across five WHO dimensions were studied. RESULTS: Prevalence of adherence in our study was 81.3%. Among the five dimensions of adherence, distance from home (odds ratio [OR] 0.980; 95% confidence interval [CI] 0.964-0.997) among socioeconomic determinants, frequent adherence counseling (OR 8.737; 95% CI 4.076-18.727) among health system-related, drug regimen (OR 2.202; 95% CI 1.023-4.738) and absence of side effects (OR 3.293; 95% CI 1.473-7.365) among therapy related, absence of substance abuse (OR 2.747; 95% CI 1.209-6.243), and perceived change in health status (OR 4.196; 95% CI 1.613-10.915) among patient-related dimension were found to be significantly associated with adherence to ART, while clinical condition dimension did not play a significant role. CONCLUSION: The ART adherence rate is still below satisfactory levels for long-term viral load suppression. WHO multidimensional approach - which was found to be quite relevant in our study setting - could be applied to effectively solve the adherence problem in our country.

Cell cannibalism in oral cancer: A sign of aggressiveness, de-evolution, and retroversion of multicellularity.

BACKGROUND: According to Darwin's theory of evolution, complex creatures evolve from more simplistic ancestors. Dollo's law of irreversibility states that evolution is irreversible. However, cancer cells tend to follow anti-Dollo's law. Unfavorable conditions such as hypoxia, acidic pH and low nutrients cause the cancer cells to switch their lifestyle atavistically in order to survive. They start behaving like a unicellular organism. There is a switch from normal metabolism to Warburg effect and finally cannibalism. Cannibalism is a cell eating cell phenomenon. It is defined as a large cell enclosing a smaller one within its cytoplasm and is known by odd names such as "bird's eye cells" or "signet ring cells." Smaller tumor cells are found in the cytoplasm of larger tumor cells with crescent-shaped nucleus. Cannibalistic cells (CCs) are a feature of aggressive tumors. These cell types are vulnerable to metastasis. AIM: The aim of this study is to identify CCs in various histological grades of oral squamous cell carcinoma (OSCC) and to relate them with the pattern of invasion, lymphocytic response (LR), and mitotic figures (Mfs). The purpose of the article is to establish it as a marker of aggressiveness and metastasis and as an evidence of de-evolution and retroversion of multicellularity. MATERIALS AND METHODS: Sixty-five histologically confirmed cases of OSCC were studied. Pattern of invasion, LR, number of CCs, and Mfs were recorded on 5 µ hematoxylin and eosin-stained tissue sections. ANOVA and t-test were applied; P < 0.05 was considered statistically significant. RESULTS: CCs were more in sections with patchy LR, increased Mfs, and grade IV pattern of invasion. CONCLUSION: With increase in dedifferentiation, tumor cells start behaving like unicellular organisms with cell eating cell characteristics.

An Immunohistochemical and Polarizing Microscopic Study of the Tumor Microenvironment in Varying Grades of Oral Squamous Cell Carcinoma.

BACKGROUND: Invasion of epithelial cells into the connective tissue brings about massive morphological and architectural changes in the underlying stroma. Myofibroblasts reorganize the stroma to facilitate the movement of tumor cells leading to metastasis. The aim of this study was to determine the number and pattern of distribution of myofibroblasts and the qualitative and quantitative change that they cause in the collagen present in the stroma in various grades of oral squamous cell carcinoma (OSCC). METHODS: The study was divided into two groups with group I (test group, 65 cases) consisting of 29 cases of well-differentiated squamous cell carcinoma, 25 moderately differentiated SCC, and 11 poorly differentiated SCC, and group II (control group) consisting of 11 cases of normal mucosa. Sections from each sample were stained with anti-α-smooth muscle actin (α-SMA) antibodies, hematoxylin and eosin, and Picrosirius red. Several additional sections from each grade of OSCC were stained with Masson's trichrome to observe the changes in collagen. For the statistical analysis, Fisher's exact test, Tukey's post hoc honest significant difference test, ANOVA, and the chi-square test were used, and p < .05 was considered statistically significant. RESULTS: As the tumor stage progressed, an increase in the intensity α-SMA expression was seen, and the network pattern dominated in more dedifferentiated carcinomas. The collagen fibers became thin, loosely packed, and haphazardly aligned with progressing cancer. Additionally, the mean area fraction decreased, and the fibers attained a greenish yellow hue and a weak birefringence when observed using polarizing light microscopy. CONCLUSIONS: Myofibroblasts bring about numerous changes in collagen. As cancer progresses, there isincrease in pathological collagen,which enhances the movement of cells within the stroma.

Omission of quality assurance during data entry in public health research from India: Is there an elephant in the room?

As the adage, "Garbage in, Garbage out" goes, data entry errors may lead to erroneous results and conclusions. Quality assurance during data entry is one of the most neglected components of research and is conspicuously missing in most of the reporting standards. In this study, we reviewed research studies published in Indian Journal of Public Health and Indian Journal of Community Medicine during 2014-2016 and determined the proportion of papers reporting on quality assurance during data entry. Of 110 papers, only 6 (5.5%) papers explicitly included a statement about data quality assurance, with two studies reported to have performed double entry and validation, considered the gold standard in quality-assurance of data entry. This is highly unacceptable. We hereby appeal to the community of researchers, peer reviewers, and journal editors in India to pay attention to this important aspect of research and make reporting of quality assurance of data entry mandatory in every published paper.

Adverse eating behavior and its association with obesity in Indian adolescents: Evidence from a nonmetropolitan city in India.

INTRODUCTION: With the so-called modernization, the epidemiological and sociocultural context of adolescents in developing countries is rapidly changing and is affecting their eating behavior and dietary choices. The objective of our study is twofold. First, our study seeks to find whether there is a prevalence of the adverse eating behaviors among the adolescents. Second, our study seeks to examine whether the prevalence of the adverse eating behavior is related to obesity and quantifies their association of with body mass index (BMI) status. MATERIALS AND METHODS: A cross-sectional school-based study was conducted in 13-15-year-old adolescents from schools of Aligarh, India, with prevalidated study tools and standardized anthropometric measures. The Z-scores were found by the WHO recommended AnthroPlus. RESULTS: The results indicate a high prevalence of different adverse eating behaviors. The dietary behavior was found to be poor in 19.3%, fair in 54.4%, and good in only 26.3% of the study population. The mean BMI for age Z-score was found to be 0.87 and 0.02 in poor and fair dietary behavior. The odds of being overweight and obese were high (1.82 [1.20-2.78]) in those with poor dietary behavior. CONCLUSIONS: Our findings suggest that more research and timely intervention in adverse eating behaviors are much needed in India before this widely neglected problem acquires even more alarming and gigantic proportions.
