Internet Addiction and Its Association with Demographic Variables, Depression, Anxiety, and Psychological Well-being in College Students. Ann Neurosci 2024;31:21-27. [PMID: 38584979 PMCID: PMC10996870 DOI: 10.1177/09727531231171979] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

Background

Internet is an integral part of the daily life of everyone. Internet addiction (IA) is one of the major concerns, specifically among young adults. The association between IA, depression, anxiety, and psychological well-being (PWB) is least studied in young adults.

Purpose

To evaluate IA and its association with psychological morbidity and PWB in a larger sample size. In addition, to examine the factors that are associated with IA.

Methods

A total of 1287 young students were evaluated in the present study. Participants were evaluated on the Internet Addiction Test (IAT), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Psychological Well-Being Index-22.

Results

The mean age of the study's participants is 19.5 years. The majority were female (68.9%), from nuclear families (61.8%), and belonged to urban localities (61.5%). On IAT, 15.9% had a presence of IA with a cut-off score of 50. 27.4% and 20.5% had a presence of depression and anxiety with a cut-off score of 10 on the PHQ-9 and GAD-7, respectively. Approximately two-thirds (66.7%) reported poor PWB. IA had a significant positive association with depression and anxiety and a negative association with PWB. Male students, the presence of depression, anxiety, and poor PWB were independent factors associated with IA.

Conclusion

Internet addiction is highly prevalent among college students and has a significant association with anxiety, depression, and poor PWB. There is a need to develop a structured plan, educational strategy, and program to minimize IA in young adults.

Outbreak investigation of acute febrile illness from the Himalayan foothills: Solving the puzzle of fever

In September 2022, Panchkula Civil Hospital reported an outbreak of acute febrile illness (AFI) in Pinjore, located in the Himalayan foothills, Haryana, North India. There was an upsurge of fever cases. Blood samples were taken from suspected patients (n = 58) with AFI and subjected to serology of dengue, chikungunya, Japanese encephalitis, leptospira and scrub typhus. The samples were also screened for West Nile & Zika virus RNA using real-time PCR. Viral strains were characterized by sequencing. Of the 58 cases of AFI, Dengue could be identified in 45 (77.58%) followed by JE and Chikungunya in 2 cases each (3.44%), respectively. Among Dengue positive cases, 44 had monoinfection (97.77%) and 1 patient had dengue and JE. None were positive for Zika, West Nile, Scrub typhus, and Leptospira with the testing protocol. Four patients developed dengue with warning signs, such as abdominal pain in one patient and recurrent vomiting in the remaining three. The dengue serotype could be determined in 17 samples and revealed serotype 2. Molecular evolution analysis based on the complete envelope gene revealed that all DENV-2 strains (n = 13) circulated in the outbreak area belonged to the DENV-2 cosmopoliton genotype. In the early stages of infection, relying only on clinical manifestations is ineffective, so both molecular and serological assays along with clinical diagnosis are noteworthy for determining the aetiology of AFI.

Awareness Regarding Antimicrobial Resistance and Antibiotic Prescribing Behavior among Physicians: Results from a Nationwide Cross-Sectional Survey in India

(1) Background: Understanding the physicians' knowledge, attitudes, and antimicrobial prescribing behavior is a crucial step towards designing strategies for the optimal use of these agents. (2) Methods: A cross-sectional online survey was conducted among clinicians across India between May and July 2022 using a self-administered questionnaire in English comprising 35 questions pertaining to demographic characteristics, knowledge, attitude, and practices domains. (3) Results: A total of 544 responses were received from 710 physicians contacted. Sixty percent of participants were males, with mean age of 34.7 years. Mean ± Standard Deviation scores for knowledge, attitude, and practices domains were 8 ± 1.6, 20.2 ± 3.5, and 15.3 ± 2.1, respectively. Higher scores were associated with basic [odds ratio (95% Confidence Interval), p value: 2.95 (1.21, 7.2), 0.02], medical and allied sciences [2.71 (1.09, 6.67), 0.03], and central zone [3.75 (1.39, 10.12), 0.009]. A substantial proportion of dissatisfactory responses were found regarding hospital antibiograms, antibiotics effective against anaerobes, WHO AWaRe (access, watch, and reserve) classification of antibiotics, and the role of infection prevention and control (IPC) measures in the containment of antimicrobial resistance (AMR). (4) Conclusions: There is a need to sensitize and educate clinicians on various issues related to antimicrobial use, such as antibiograms, double anaerobic cover, IPC practices, and guideline-based recommendations, to curb the AMR pandemic.

Efficacy and safety of pan-genotypic sofosbuvir and velpatasvir in patients with hepatitis C and HIV coinfection on dolutegravir-based antiretroviral therapy

Hepatitis C virus (HCV) infection is more prevalent in people living with HIV-AIDS (PLHA) and portends a poorer prognosis. Pharmacokinetic studies suggest the absence of significant interaction between velpatasvir and dolutegravir which has been recently recommended as part of preferred first-line antiretroviral therapy (ART) regimens by WHO. However, clinical data on the use of velpatasvir-based regimen in PLHA taking dolutegavir is lacking. Hence, we aimed to assess the efficacy and safety of sofosbuvir and velpatasvir (SOF + VEL) in HCV and HIV coinfected patients on dolutegravir-based ART. Forty-five consecutive PLHA with HCV coinfection on dolutegravir-based ART were prospectively enrolled. All patients were treated SOF + VEL for 12 weeks. Complete haemogram, liver and renal function tests were assessed at baseline, 4 weeks and at end of treatment. Sustained virological response (SVR) was assessed at 12 weeks after end of treatment. The majority were males (95.5%) with a mean age of 32.8 ± 12.3 years. Cirrhosis was present in 6 (13.3%) patients. All patients completed 12 weeks of therapy with SOF + VEL, but SVR could not be assessed in two patients. Forty-two (97.7%) of the remaining 43 patients attained SVR-12. SVR-12 rate was 97.7% and 93.3% by per protocol and intention to treat analysis, respectively. No grade III/IV adverse events were reported, and there was no worsening of blood counts, liver or renal function test parameters. The pan-genotypic regimen of SOF + VEL is safe and effective in PLHA with HCV coinfection who are on dolutegravir-based ART.

An Evaluation of Malaria Surveillance System in Punjab, India, 2020

Background

India accounted for 6% of global burden of malaria with 95% population residing in malaria endemic areas. However, Punjab is in the malaria elimination phase with annual parasite incidence (API) <1/1000 population.

Objectives

We evaluated malaria surveillance system in Punjab using CDC's updated guidelines for evaluating public health surveillance systems to provide recommendations for strengthening the existing system and to overcome the challenges in the path of malaria free Punjab.

Methods

We chose two districts of Punjab, Amritsar (lowest API) and Mansa (highest API), interviewed stakeholders, and performed a retrospective desk review. We evaluated the overall usefulness of the system and assessed seven attributes at state, district, health facility, and village level during July-August 2020.

Results

In Punjab, there was progressive decline in the malaria cases from 2,955 cases in 2009 to 1,140 in 2019 and no malaria deaths since 2011. Regarding various attributes, overall score for flexibility was good (85.9%); average for simplicity (77%), acceptability (74%), data quality (74%), and timeliness (70%); and poor for representativeness (59%) and stability (57%).

Conclusions

Malaria surveillance system was useful in analyzing the trends of morbidity and mortality and for generating data to drive policy decisions. To improve stability, representativeness, and acceptability, surveillance staff should not be engaged in supplemental work, and reports from private sector must be ensured. Supportive supervision and regular trainings should be carried out regarding reporting formats, guidelines, and timely epidemiological investigations to improve timeliness, data quality, and simplicity.

Psychological distress and related factors regarding COVID-19 among the ancillary hospital staff: A cross-sectional study

Background

Healthcare workers (HCWs) are at the front line of the Coronavirus disease (COVID-19) outbreak response. They have faced great risks to both physical and mental health. We aimed to assess the psychological effect of COVID-19 among ancillary hospital staff.

Methods

A cross-sectional study was conducted among 267 on-duty ancillary hospital staff using a semi-structured questionnaire to assess their psychological status and risk perception. In addition, their knowledge, attitude, and practices (KAP) and risk perception were also assessed. The General Health Questionnaire (GHQ-12) was used to screen for psychological distress.

Results

Among 267 participants, the mean (±SD) age was 33.5 (7.6) years. The majority knew about the symptoms of COVID-19 (88.4%), droplet spread (99.3%), and the importance of isolation (99.3%). About 35.2% were worried about infecting family members, while 26.2% were worried about colleagues at the frontline. Only 38.9% of them had a good knowledge score. Participants with high school and above education level had significantly good knowledge about COVID-19 (OR = 1.99; 95% CI = 1.17- 3.39) than those with primary school or below. Being female (OR 1.99; 95% CI 1.17-3.39) and working with COVID-19 patients (OR 3.88, 95% CI 1.77-8.47, P = 0.001) was associated with psychological distress.

Conclusion

The ancillary hospital staff had insufficient knowledge regarding the risk factors of COVID-19 but possessed positive attitudes and practices. Continued health education and appropriate psychological interventions may improve understanding and reduce psychological distress.

Impact of virtual continued medical education on carbon footprint and awareness of digital sobriety: A retrospective cross-sectional study among public health professionals in India

Background

Due to the COVID-19 pandemic, physical meetings and continuing medical education (CMEs) are being conducted in virtual mode. Digital sobriety has been advocated as a strategy for controlling the environmental emission from online events. The present study was undertaken to assess the impact of virtual CMEs on the environment and the participants' perception, knowledge, attitude, and practices of digital sobriety during the CMEs.

Methods

A retrospective cross-sectional Google form-based online study was conducted among the 1,311 registrants of 23 virtual CMEs hosted in India. A pre-tested English questionnaire was used to collect the data. The potential carbon footprint of the significant physical CME activities and the carbon emission (CE) of the virtual CMEs were estimated. Among the registrants contacted, 251 consented and participated in the study.

Results

The CE of the virtual CMEs was 0.787 metric tons of carbon dioxide equivalent (MT CO2 Eq). If the CMEs were conducted physically, the potential CE was estimated to be 290.094 MT CO2 Eq. The awareness rate of digital sobriety was 35%. Most of the participants (58.7%) from the current study preferred the hybrid mode of CMEs.

Conclusions

Virtual, digitally sober CMEs have reduced the potential CE by 99.7% compared to physical CMEs in India. The awareness and knowledge about digital sobriety is low in India. Knowledge, networking, social interactions, and overall satisfaction were relatively lower in the virtual mode of CMEs than in the physical mode.

Human rabies control in the era of post-COVID-19: a call for action

Following the COVID-19 pandemic, there has been a sharp increase in rabies cases and deaths. Rabies outbreaks are being reported worldwide. Multiple disruptions in Rabies control occurred during the pandemic, significantly affecting lower-income countries. Countries need to develop specific action plans to become 'rabies free' by 2030.

Effect of digitization of medical case files on doctor patient relationship in an Out Patient Department setting of Northern India: A comparative study

Background: Digitization of health records and health delivery processes in health care settings may have an impact on the Patient-Physician communication, wait times, that affect the overall patient satisfaction with the health care services. Aim & Objective: We ascertained the effect of digitization of medical case files on the doctor patient relationship (DPR) domain of patient satisfaction at an urban primary health center in India. Settings and Design: Comparative, cross-sectional study in primary health centres. Methods and Material: The patient satisfaction was compared between the patients attending the Public Health Dispensary (PHD) that uses digitized medical case file system and a Civil Dispensary (CD) which follows the conventional paper based medical records, using a Patient Satisfaction Questionnaire (PSQ). Statistical analysis used: Univariate analysis was done by chi-square test and adjusted analysis was done by multiple linear regression. Results: Patient satisfaction in DPR was found to be same between the digitized medical case files based and conventional OPD (p=0.453). Significantly higher overall patient satisfaction was reported in the conventional paper based OPD than the digitized OPD (p<0.001). Conclusions: Patient satisfaction towards the doctor-patient relationship (DPR) was same between paper based OPD and the digitized medical case files based OPD.

Comprehensive assessment of age-specific mortality rate and its incremental changes using a composite measure: A sub-national analysis of rural Indian women

Background

Diverse socio-economic and cultural issues contribute to adverse health outcomes and increased mortality rates among rural Indian women across different age categories. The present study aims to comprehensively assess age-specific mortality rates (ASMR) and their temporal trends using a composite measure at the sub-national level for rural Indian females to capture cross-state differences.

Materials and methods

A total of 19 states were included in the study to construct a composite age-specific mortality index for 2011 (base year) and 2018 (reference year) and examine the incremental changes in the index values across these years at the sub-national level in India. Sub-index values were calculated for each component age group and were subsequently used to compute the composite ASMR index using the geometric mean method. Based on the incremental changes, the performance of states was categorized into four different typologies.

Results

Improvement in mortality index scores in the 0-4 years age group was documented for all states. The mortality rates for the 60+ age group were recorded to be high for all states. Kerala emerged as the overall top performer in terms of mortality index scores, while Bihar and Jharkhand were at the bottom of the mortality index table. The overall mortality composite score has shown minor improvement from base year to reference year at all India level.

Conclusion

An overall reduction in the mortality rates of rural Indian women has been observed over the years in India. However, in states like Bihar and Jharkhand, mortality is high and has considerable scope for improvement. The success of public health interventions to reduce the under-five mortality rate is evident as the female rural mortality rates have reduced sizably for all states. Nevertheless, there is still sizable scope for reducing mortality rates for other component age groups. Additionally, there is a need to divert attention toward the female geriatric (60+ years) population as the mortality rates are still high.

Trends in willingness to receive COVID-19 vaccines among healthcare workers in India: Findings from repeated cross-sectional national surveys

Background

COVID-19 vaccination of the healthcare workers (HCWs) is a key priority in the fight against the SARS-CoV-2 pandemic. India launched its COVID-19 vaccination program in January 2021. We aimed to understand the trends in willingness to receive COVID-19 vaccines and its associated factors among HCWs in India.

Methods

Using a repeated cross-sectional survey design, we collected information from HCWs in three critical time points: before (n = 937, October 2020), during (n = 1346, January 2021); and after (n = 812, May 2021) the introduction of COVID-19 vaccines in India. The third survey coincided with the peak of the second wave of COVID-19 pandemic in India.

Findings

Of the study participants, 43.7, 60.2, and 73.2% were willing to receive COVID-19 vaccines during the first, second and third rounds of surveys, respectively. In multivariable logistic regression analysis, participants who trusted the health care system were more likely to report willingness to receive a COVID-19 vaccine; medical trust emerged as a significant factor in all the three rounds of surveys (First survey-aOR: 2.24, 95% CI: 1.67-2.99; Second survey-aOR: 3.38, 95% CI: 2.64-4.33; Third survey-aOR: 2.54, 95% CI: 1.65-3.91). Having confidence in domestic vaccines (Second survey-aOR: 2.21, 95% CI: 1.61-3.02; Third survey-aOR: 2.05, 95% CI: 1.24-3.37); and high perceived risk of contracting COVID-19 (Second survey-aOR: 1.48, 95% CI: 1.13-1.93; Third survey-aOR: 2.02, 95% CI: 1.31-3.13) were found to be associated with willingness to receive vaccines. Among socio-demographic characteristics, being married (aOR: 1.71, 95% CI: 1.08-2.71) and having high socio-economic status (aOR: 3.01, 95% CI: 1.65-5.51) emerged as significant factors associated with willingness to receive COVID-19 vaccines in the third round of the surveys.

Interpretation

Willingness to receive COVID-19 vaccine increased with time, as the severity of the pandemic increased. To increase COVID-19 acceptance and coverage among HCWs, it is important to instill confidence in domestic vaccines and assist in accurate assessment of risk toward contracting COVID-19 infection.

Neuronal cell death mechanisms in Alzheimer's disease: An insight

Regulated cell death (RCD) is an ordered and tightly orchestrated set of changes/signaling events in both gene expression and protein activity and is responsible for normal development as well as maintenance of tissue homeostasis. Aberrant activation of this pathway results in cell death by various mechanisms including apoptosis, necroptosis, pyroptosis, ferroptosis, and autophagy-dependent cell death. Such pathological changes in neurons alone or in combination have been observed in the pathogenesis of various neurodegenerative diseases including Alzheimer's disease (AD). Pathological hallmarks of AD focus primarily on the accumulation of two main protein markers: amyloid β peptides and abnormally phosphorylated tau proteins. These protein aggregates result in the formation of A-β plaques and neuro-fibrillary tangles (NFTs) and induce neuroinflammation and neurodegeneration over years to decades leading to a multitude of cognitive and behavioral deficits. Autopsy findings of AD reveal massive neuronal death manifested in the form of cortical volume shrinkage, reduction in sizes of gyri to up to 50% and an increase in the sizes of sulci. Multiple forms of cell death have been recorded in neurons from different studies conducted so far. However, understanding the mechanism/s of neuronal cell death in AD patients remains a mystery as the trigger that results in aberrant activation of RCD is unknown and because of the limited availability of dying neurons. This review attempts to elucidate the process of Regulated cell death, how it gets unregulated in response to different intra and extracellular stressors, various forms of unregulated cell death, their interplay and their role in pathogenesis of Alzheimer's Disease in both human and experimental models of AD. Further we plan to explore the correlation of both amyloid-beta and Tau with neuronal loss as seen in AD.

Community health workers willingness to participate in COVID-19 vaccine trials and intention to vaccinate: A cross-sectional survey in India

Background

Vaccine hesitancy is of considerable concern as it threatens the great potential of a vaccine against COVID-19. This study aims to determine factors associated with community health workers’ willingness to participate in clinical trials of COVID-19 vaccine, and their vaccination intention, in India.

Methods

A cross-sectional study was conducted among 377 community health workers using self-administered anonymous questionnaire during the lockdown periods in India. Participant's socio-demographics, willingness-to-participate in COVID-19 vaccine trials, intention to accept COVID-19 vaccine were recorded in a Likert scale. Data were analysed descriptively, and a multivariate logistic regression model was used to investigate factors associated with willingness to participate and accept the vaccine.

Results

Among 377 CHWs, 70 (19%) intended to participate in COVID-19 vaccine trial, 151 (40%) responded positively regarding their intention to get vaccinated. Those with knowledge on development of COVID-19 vaccine [aOR 3.05 (95% CI: 1.18–7.88), p = 0.021], and men [aOR 3.69 (95% CI: 1.51–8.97), p = 0.004] were more willing to participate in clinical-trial, while an undergraduate degree, and trust in domestic vaccines were identified as deterrents for the same. Perceiving COVID-19 as risk [aOR 2.31 (95% CI: 1.24–4.31), p = 0.009], and male gender [aOR 2.39 (95% CI: 1.17–4.88), p = 0.017] were factors associated with intention to get vaccinated. Respondents who had knowledge about COVID-19 virus were less likely to uptake the hypothetical vaccine [aOR 0.32 (95% CI: 0.12–0.88), p = 0.027].

Conclusions

Increasing knowledge regarding COVID-19 is not enough to improve vaccine acceptance rates. Targeted interventions addressing socio-demographic determinants related to COVID-19 vaccination should help improve acceptance.

Sociodemographic Determinants of Willingness and Extent to Pay for COVID-19 Vaccine in India

Background

Responding to the fast transmission rates and increasing fatality rates, countries across the world expedited the development and deployment of the vaccine for coronavirus disease 2019 (COVID-19). Evaluation of individuals' willingness to pay (WTP) would provide pertinent information regarding future demand and financing preferences, which shall help to devise the effective payment strategy for COVID-19 vaccination.

Methods

A nationwide, cross-sectional, and self-administered online survey using a structured questionnaire was conducted to identify the sociodemographic determinants of willingness and extent to pay for COVID-19 vaccine in India. A non-probability convenience sampling followed by snowball sampling was employed to recruit participants (n = 3,341). The likelihood of sociodemographic determinants to predict willingness and extent to pay was modeled using the multivariate binary logistic regression analysis.

Results

Out of 3,341 participants, 68% (n = 2,271) were willingness to pay for COVID-19 vaccine. Results showed significantly higher odds for willingness to pay among participants who were single [adjusted odds ratio (aOR) = 1.394, p < 0.01] and having a family size of 4 members (aOR = 1.346, p < 0.01). The adjusted odds ratio sizably increased from 1.396 for participants whose monthly income was between INR 10,000 and 20,000/month to 2.240 for participants whose monthly income was above INR 50,000/month. Further, out of 2,271 of those participants who were willingness to pay for COVID-19 vaccine, majority (n = 1,246, 54.9%) of participants were willingness to pay below 50% of COVID-19 vaccine cost. This study found that those who are single (aOR = 0.688, p < 0.01), having an income between INR 20,000 and 50,000/month (aOR = 0.686, p < 0.05), and those who belonged to socially disadvantaged category (aOR = 0.450, p < 0.01) were estimated to have significantly lower odds of willingness to pay more than 50% of COVID-19 vaccine cost.

Conclusion

This study observed that majority of those participants who willingness to pay for COVID-19 vaccine were willingness to pay only up to 50% of COVID-19 vaccine and income was observed as a precursor predictor of the willingness and extent to pay for COVID-19 vaccine. The understanding on the willingness and extent to pay for COVID-19 vaccine and its sociodemographic determinants will be helpful for making the strategic decisions related to the financing of COVID vaccine in India.

Suicide deaths among medical students, residents and physicians in India spanning a decade (2010-2019): An exploratory study using on line news portals and Google database

BACKGROUND

Despite having one of the world's largest medical education consortium, India lacks a comprehensive and nationally representative data on suicide deaths among medical students and physicians unlike the one found in most of the developed nations of the world.

AIM

We aimed to explore the different characteristics of suicide deaths among medical students, residents and physicians in India over a decade (2010-2019).

METHODS

Content analysis of all suicide death reports among medical students, residents and physicians available from online news portals and other publicly available sites was done. Search was done retrospectively using pertinent search words individually or in combination with language restricted to Hindi and English and timed from January 2010 to December 2019. Reports on completed suicide by allopathic medical students, residents and physicians from India were included. Socio-demographic and suicidological variables were analysed using R software.

RESULTS

A total of 358 suicide deaths among medical students (125), residents (105) and physicians (128) were reported between 2010 and 2019. Around 7 out of 10 suicides happened before the age of 30 and had mean age 29.9 (±12.2) years. Female residents and physicians were younger than their male counterparts at the time of suicide. Overall maximum suicide deaths were concentrated in South India except the state of Kerala. The specialty of anesthesiology (22.4%) followed by obstetrics-gynaecology (16.0%) had the highest suicide deaths. Violent suicide methods were more commonly used by all, with hanging being the most common mean of suicide. Academic stress among medical students (45.2%) and residents (23.1%), and marital discord among physicians (26.7%) were the most noticeable reasons for suicide. Mental health problems were the next most common reason in medical students (24%) and physicians (20%) while harassment (20.5%) was in residents. Twenty six percent had exhibited suicide warning signs and only 13% had ever sought psychiatric help before ending their lives. A total of nine reports of suicide pact were found with the average deaths per pact being 2.4 and predominantly driven by financial reasons.

CONCLUSION

Academic stress among medical students and residents, and marital discord in physicians emerged as the key reasons for suicide. However, this preventable domain should be further explored through focused research. This is the first of its kind study from India which attempted to explore this vital yet neglected public health issue using the most feasible and practical method of online news content-based analysis.

Parents' Perceptions and Intention to Vaccinate Their Children Against COVID-19: Results From a Cross-Sectional National Survey in India

Background

Despite the success of adult vaccination against COVID-19, providing vaccines to children remains a challenge for policymakers globally. As parents are primary decision-makers for their children, we aimed to assess parents' perceptions and intentions regarding COVID-19 vaccination in India.

Methods

A cross-sectional web-based study was designed, parents or caregivers (N = 770) were recruited through snowball sampling using Google form. Cross-tabulation was performed by parents' intention to vaccinate their children against COVID-19 virus with sociodemographic characteristics and their risk perception toward COVID-19, trust in the healthcare system, and their history of vaccine hesitancy behavior. Multivariable logistic regression analysis was performed to compute the predictors of child vaccination intention among Indian parents.

Results

Seven hundred and seventy parents across the country have completed the survey. Of the 770 participants, 258 (33.5%) have shown intent to vaccinate their children. The stated likelihood of child vaccination was greater among parents who had a bachelor's degree or higher education (aOR: 1.98, 95% CI: 1.15-3.51); as well as among parents who intended to vaccinate themselves (aOR: 2.35, 95% CI: 1.30-4.67). Parental concerns centered around vaccine safety and side effects.

Conclusion

Indian parents reported high knowledge of the COVID-19 virus and were aware of the development of a vaccine. However, about one-third of parents intended to vaccinate their children, and about half of them were not sure whether to vaccinate their children or not against the COVID-19 virus. The study highlighted the need for health promotion strategies that promote vaccine uptake among parents.

Predictors of COVID-19 positivity among patients presenting to screening clinic in a dedicated COVID-19 hospital, in chandigarh, India - A cross-sectional study

Background:

The aim of this study was to analyze the clinical features of patients attending the screening clinic of a dedicated COVID-19 hospital (DCH), including COVID-19 RT-PCR test positivity rate, symptom predictors for COVID-19 positivity, the proportion of recovery, and the mortality among COVID-19 positive cases.

Methods:

We conducted a cross-sectional study of the patients who reported in the screening clinic of a DCH. Data were retrieved from medical records. Step-wise binary logistic regression was applied to determine the symptom predictors for determining the likelihood of the suspects turning out to be COVID-19 positive.

Results:

A total of 573 patients reported to the screening clinic were enrolled, and their median age was 36 ± 14 years. Of the total patients, 237 (41%) were females and 112 (20%) patients were COVID-19 suspects. Fifty (45%) suspects tested COVID-19 positive. The majority of the positives had complaints of cough, fever, and sore throat. Running nose (OR = 7.951) and history of contact with a COVID-19-positive case (OR = 169.9) were found to be statistically significant symptom predictors for COVID-19 positivity. All patients recovered with nil case fatality.

Conclusion:

Running nose and history of contact with COVID-positive patients were significant predictors for COVID-19 positivity. In this pandemic state, patients who present with any of the upper respiratory infection (URI) symptoms such as cough, sore throat, running nose, headache, and loss of taste/smell should be tested for COVID-19 for early identification and isolation to break the chain of transmission. The public should be encouraged to undergo COVID-19 testing if they develop any of the URI symptoms.

Factors Influencing COVID-19 Vaccination Intentions Among College Students: A Cross-Sectional Study in India

Background: Students act as messengers in delivering effective messages for better uptake of health-promoting behavior. Understanding their knowledge about coronavirus disease 2019 (COVID-19), intentions to use the COVID-19 vaccine, and its associated factors will help develop promising strategies in vaccine promotion concerning the current COVID-19 pandemic. Methods: A cross-sectional online survey was carried out among students in the healthcare and non-healthcare sectors to assess their intentions to get vaccinated against the COVID-19. A non-probability snowball sampling technique was used to recruit study participants (N = 655) through social media platforms and emails. Study participants were recruited across the country, including six major geographical regions (Eastern, Western, Northern, Southern, North-east, and Central) in India between November 2020 and January 2021 before the introduction of the COVID-19 vaccine. Descriptive statistics were used to present the sociodemographic, and vaccine-related behaviors of the study participants. Key determinants that likely predict vaccine acceptance among students were modeled using logistic regression analysis. For each analysis, p < 0.05 was considered significant. Results: A total of 655 students were recruited, 323 from healthcare and 332 from non-healthcare sectors, to assess their intentions to receive the COVID-19 vaccine. Of the 655 students, 63.8% expressed intentions to receive the COVID-19 vaccine. The acceptance was higher among non-healthcare students (54.07 vs. 45.93%). At the time of the study, 27.8% of the students indicated that they had been exposed to a confirmed COVID-19 patient. A vast majority (93.4%) of the students knew about the COVID-19 virus, and most (89.3%) of them were aware of the development of a COVID-19 vaccine. The history of vaccine hesitancy was found to be low (17.1%). Only one-third (33.4%) of the students showed concern about contracting COVID-19. Trust in the healthcare system [adjusted odds ratio (aOR): 4.13; (95% CI: 2.83-6.04), p < 0.00] and trust in domestic vaccines [aOR: 1.46; (95% CI: 1.02-2.08), p < 0.05] emerged as the significant predictors of student's intention to get vaccinated. Higher acceptance for vaccine was observed among students in the non-healthcare [aOR: 1.982; 95% CI: 1.334-2.946, p < 0.00]. Conclusion: This study shows that the Indian college students had relatively high levels of positive intentions to receive COVID-19 vaccines, although about one-third were not sure or unwilling to receive the vaccine, highlighting possible vaccine hesitancy. Informational campaigns and other strategies to address vaccine hesitancy are needed to promote uptake of COVID-19 vaccines.

Management of a religious mass gathering in North India: Parkash Utsav 550

BACKGROUND

The 550th Birth Anniversary (Parkash Utsav) celebrations of Shri Guru Nanak Dev Ji, the first Sikh Guru, was celebrated with great devotion and fervor at Sultanpur Lodhi, Punjab, India, from November 1 to 14, 2019. The authors aimed to shed light on the planning and management of the event and the factors that led to its success.

METHODS

The researchers conducted key informant interviews with authority figures, resource mapping, and observations. The researchers focused on the event's medical lounge. Open-ended questions were asked to gather information regarding various measures taken to organize and execute the event. The data were entered and analyzed using Microsoft Excel 7.0 and SPSS 20.0 (Trial version).

RESULTS

About three million people attended the Parkash Utsav 550 celebrations. Three tent cities were set up in Sultanpur Lodhi with the consideration for incoming road traffic. The state government deployed 820 medical personnel, including 150 doctors, 470 paramedics, and 200 volunteers. A total of 19,521 patients were seen in the outpatient department of the Medical Lounge. The government made sufficient arrangements for various services, such as drinking water, langar (or community kitchens), sanitation, and security. Approximately 37 langar halls were constructed in the town to provide healthy food to the devotees. An integrated command and control center was set up for surveillance and monitoring. For the convenience of the devotees, 1,908 toilets, 1,476 urinals, and 132 bathing units were installed. The District Administration of Kapurthala launched an event-specific mobile application, "Par-kash Utsav 550," for the use of pilgrims as well as government officials. No stampedes, outbreaks, and fire incidents were reported.

CONCLUSIONS

Parkash Utsav 550 was successfully celebrated. Studying the Parkash Utsav 550 presented a unique opportunity to generate an evidence base for the development of solutions and recommendations for the prevention, management, and control of infectious diseases, stampedes, and fire incidents during mass gatherings. In-depth studies of the Parkash Utsav in the future are required to produce evidence for context-specific measures for addressing the complex health challenges of mass gatherings.

COVID-19 in Punjab, India: Epidemiological patterns, laboratory surveillance and contact tracing of COVID-19 cases, March-May 2020

Background

In Punjab, first COVID-19 case was detected on March 5, 2020 followed by multiple clusters. Understanding the epidemiology of reported COVID-19 cases helps decision makers in planning future responses. We described the epidemiological patterns, laboratory surveillance and contact tracing of COVID-19 cases in Punjab.

Methods

We analysed state's COVID-19 data from March-May 2020 to describe time, place and person distribution. We analysed the laboratory surveillance and contact tracing reports to calculate frequency of testing, sample positivity rate (PR) and contacts traced per case.

Findings

A total of 2256 cases were reported from March-May 2020 (attack rate 75 cases/million and case fatality rate 2%). Attack rate was higher among males (81 cases/million males) and maximum affected age group was 60-69 years (164∙5 cases/million). Five of 22 districts reported almost half cases in May's first week. Mortality rate was highest among individuals >60 years (six deaths/million) and males (two deaths/million males). Of 45 deaths, 41 reported comorbidities [(hypertension (42%), diabetes (40%)]. COVID-19 testing increased from 46 samples/day (PR: 2%) in March's first week to 4000 samples/day (PR: 2∙5%) by May's end (2752 tests/million). Amritsar conducted 2035 tests/million (highest PR: 6∙5%) while Barnala conducted 4158 tests/million (lowest PR: 1%). For 2256 cases, 19,432 contacts were traced (nine contacts/case) with 11% positivity rate.

Interpretation

COVID-19 in Punjab mostly affected males, >60 years of age and individuals with comorbid conditions. Many districts with less testing and contact tracing had higher positivity rate. We recommended to implement and ensure adequate testing and contact tracing in all the districts of Punjab.

Multidimensional dynamic healthcare personnel (HCP)-centric model from a low-income and middle-income country to support and protect COVID-19 warriors: a large prospective cohort study

OBJECTIVES

Healthcare personnel (HCP) are at an increased risk of acquiring COVID-19 infection especially in resource-restricted healthcare settings, and return to homes unfit for self-isolation, making them apprehensive about COVID-19 duty and transmission risk to their families. We aimed at implementing a novel multidimensional HCP-centric evidence-based, dynamic policy with the objectives to reduce risk of HCP infection, ensure welfare and safety of the HCP and to improve willingness to accept and return to duty.

SETTING

Our tertiary care university hospital, with 12 600 HCP, was divided into high-risk, medium-risk and low-risk zones. In the high-risk and medium-risk zones, we organised training, logistic support, postduty HCP welfare and collected feedback, and sent them home after they tested negative for COVID-19. We supervised use of appropriate personal protective equipment (PPE) and kept communication paperless.

PARTICIPANTS

We recruited willing low-risk HCP, aged <50 years, with no comorbidities to work in COVID-19 zones. Social distancing, hand hygiene and universal masking were advocated in the low-risk zone.

RESULTS

Between 31 March and 20 July 2020, we clinically screened 5553 outpatients, of whom 3012 (54.2%) were COVID-19 suspects managed in the medium-risk zone. Among them, 346 (11.4%) tested COVID-19 positive (57.2% male) and were managed in the high-risk zone with 19 (5.4%) deaths. One (0.08%) of the 1224 HCP in high-risk zone, 6 (0.62%) of 960 HCP in medium-risk zone and 23 (0.18%) of the 12 600 HCP in the low-risk zone tested positive at the end of shift. All the 30 COVID-19-positive HCP have since recovered. This HCP-centric policy resulted in low transmission rates (<1%), ensured satisfaction with training (92%), PPE (90.8%), medical and psychosocial support (79%) and improved acceptance of COVID-19 duty with 54.7% volunteering for re-deployment.

CONCLUSION

A multidimensional HCP-centric policy was effective in ensuring safety, satisfaction and welfare of HCP in a resource-poor setting and resulted in a willing workforce to fight the pandemic.

Current status of periodontitis and its association with tobacco use amongst adult population of Sunsari district, in Nepal

BACKGROUND

Tobacco products are considered significant, but preventable factors related to initiation and progression of periodontal diseases. We assessed the prevalence of periodontitis and evaluated its association with tobacco use and other factors amongst the adult population of Sunsari district in eastern Nepal.

METHODS

A community-based, cross-sectional study was conducted in rural municipalities in the province one of eastern Nepal. A total of 440 adults were interviewed with a set of a pre-tested semi-structured questionnaire. Data on social demographics, adverse oral habits followed by periodontal clinical examination were recorded. Prevalence of periodontitis was assessed by a case definition provided by CDC-AAP. Univariate and multivariate logistic regression analysis was done to measure the association between tobacco use and other factors with periodontitis.

RESULTS

The overall prevalence of periodontitis was found to be 71.6%. Majority (85.4%) of tobacco users had periodontitis and they were significantly associated with the disease and its severity. The study identified age groups, 45-65 years (AOR = 7.58, 95% CI 3.93-14.61), plaque accumulation (AOR = 1.01, 95% CI 1.00-1.02), smoking (AOR = 3.14, 95% CI 1.36-7.27), khaini users (smokeless tobacco, AOR = 2.27, 95% CI 1.12-4.61) and teeth loss (AOR = 2.02, 95% CI 1.21-3.38) as the significant factors associated with periodontitis.

CONCLUSION

The prevalence of periodontitis is high in the surveyed rural adult population. Cigarette smoking along with the use of smokeless tobacco in the form of khaini were identified as significant factors associated with periodontitis.

The successful containment of COVID-19 outbreak in Union Territory of Ladakh, India, 2020

Objectives:

A three-member central Rapid Response Team (RRT) was deputed to Union Territory of Ladakh on 26^th March 2020, to assess the situation and support the preparedness measures including implementation of cluster containment plan and social distancing measures for coronavirus disease 2019 (COVID-19).

Methods:

Central RRT addressed the panchayat sarpanch and religious leaders, sensitized doctors and paramedical staff on COVID-19 situation; conducted situational analysis, review of records and logistics, key informant interviews of senior administrative and healthcare officials, focus group discussions with local community people and field visits to various hospitals, isolation centers, quarantine facilities, and containment zones.

Results:

A total of 14 COVID-19 cases with no deaths were reported and nine patients had recovered till 4 April 2020. The median (range) age of positive cases was found to be 32.5 (6 months–76 years) years and overall attack rate was 1.65 per 1000 population. Ladakh Government declared Chuchot Gongma, Yokma and Sankoo as the containment zones and deputed surveillance teams. A total of 2397 persons were quarantined and 496 samples were tested from Ladakh. COVID-19 sample testing, Srinagar-Leh highway opening and Iran pilgrimage returnees were the major challenges identified.

Conclusions:

The Ladakh government must continue the robust surveillance system and stringent strategies in key areas for management of COVID-19 namely – aggressive screening and testing, isolation, quarantine, hand hygiene, respiratory etiquettes and social distancing.

Analysis of performance of clinical biochemistry laboratory using Sigma metrics and Quality Goal Index

Background

Unreliable and ingenuine results issued by clinical laboratories have serious consequences for the patients. Sigma metrics is a standardized tool for Quality assessment for test performance in a laboratory.

Objective

To evaluate the performance of routine biochemistry laboratory at MMIMSR, Mullana in terms of Sigma metrics and Quality Goal Index.

Material and methods

This cross sectional study evaluated performance of 14 routine chemistry parameters using retrospective Internal Quality Control data of two levels on Siemens Dimension Rxl from Feb to Jul 2019 for CV% and EQAS reports from CMC, Vellore for Bias%. Sigma metrics was calculated using total allowable error targets as per CLIA and Biological Variability database guidelines.

Results

For level-2 IQC; TG, Chol, ALP showed excellent performance with σ ​> ​6 while σ ​< ​3 was observed for AST, Total Protein, Glucose, BUN and ALT using CLIA guidelines while in IQC Level-3 poor performers were only BUN and ALT with Ca, TG and Chol showing σ ​> ​6. Further by using Biological Variability data guidelines; 10 parameters of IQC Level-2 and 5 of IQC level-3 were poor performers with σ ​< ​3.

Conclusion

Sigma metrics is an excellent tool for performance analysis of tests performed in a clinical laboratory. Lack of precision in terms of CV% was seen for majority of the poor performers. Total allowable error targets using Biological Variability data revealed σ ​< ​3 for 10 parameters while using CLIA guidelines σ ​< ​3 was seen for only 5 parameters of IQC level-2.

Evaluation of National Injury Surveillance Centre, India, 2015-16

Background: Globally, injuries accounts for 9% of all deaths, but India account for 11%. Due to limited data on injury characteristics, National Injury Surveillance Centre (NISC) was established in 2014 in New Delhi. Aim & Objectives: To evaluate attributes of NISC and make evidence-based recommendations. Methods and Material: We conducted cross-sectional study and used US Centers for Disease Control and Prevention guidelines to assess simplicity, flexibility, acceptability, stability, timeliness, representativeness, usefulness, and data quality. We reviewed 2015 records and interviewed 20 key-informants. We used Epi-Info7 for analysis. Results: NISC captured 4043 injuries in 2015 from one hospital. Among five data entry operators, four reported lengthy format, but all reported it easy. Among ten relevant key-informants, all reported data-management software easy. System demonstrated flexibility in three variables. All 20 staff reported willingness to participate, and 90% felt quarterly reporting acceptable. Regarding stability, data was collected for 361/365 days. Quarterly reports were available but only submitted annually. Regarding usefulness, all WHO-recommended variables included. Regarding data quality, 17% data-fields were missing. Conclusion: NISC is simple, flexible, stable, acceptable and potentially useful based on data captured. Timeliness based on annual reporting is high, can be improved to quarterly. We recommend training to improve data quality and integration of additional hospitals to improve representativeness.

P1854Clinical implications of physical function and resilience in patients undergoing transcatheter aortic valve implantation

Background

Gait speed, as a measure of physical function and marker of frailty, is now routinely screened when evaluating patients with aortic stenosis (AS) for transcatheter aortic valve implantation (TAVI). Assessment of physical function is important to identify patients for whom TAVI may be futile and to assign patients to a procedural risk category. After TAVI, patients may exhibit physical resilience (improvement in physical function) or vulnerability (worsening). Characterizing the trajectory and clinical consequences of physical function after TAVI represent knowledge gaps in the field.

Purpose

Evaluate associations between physical resilience (improved gait speed) vs vulnerability (decline) after TAVI and subsequent death/hospitalization.

Methods

The REPRISE III trial compared a mechanically-expanded vs a self-expanding valve in 912 high/extreme risk patients with symptomatic AS. Patients (n=587) who underwent valve implantation and who had a gait speed recorded both pre- and 1-year post-TAVI were analyzed. Gait speed is based on the 5m walk test (slow: 5m in >6s, <0.83m/s; normal: ≥0.83m/s). Trajectory of physical function after TAVI was characterized in 2 ways. Model 1 examined 4 groups based on slow or normal gait speeds at baseline and 1-year post-TAVI. Model 2 examined gait speed change pre-TAVI to 1 year (adjusted for baseline gait speed). Using a landmark approach, the relationships between baseline and 1-year gait speed were evaluated in multivariable Cox PH models of outcomes between 1 and 2 years post-TAVI.

Results

A clinically-meaningful improvement (≥0.1m/s), no change (±0.1m/s), or decline (≥0.1/ms) in gait speed 1 year after TAVI was observed in 39%, 36%, and 26% of patients, respectively. Among the 4 groups defined by pre- and 1-year post-TAVI gait speeds, 1 to 2 year mortality or hospitalization rates were: 6.6% (normal/normal), 20.9% (normal/slow), 8.0% (slow/normal), and 21.5% (slow/slow). Adjusted hazard ratios of the 2 models are shown (Table).

Table. Outcome by Change in Gait Speed Death/Hospitalization P-value Death P-value Hospitalization P-value Adjusted HR [95% CI] Adjusted HR [95% CI] Adjusted HR [95% CI] Model 1: Baseline/1 year Gait Speed   (Normal/Normal (n=150) [referent])   Normal/Slow (n=59) 3.82 [1.61, 9.08] <0.01 2.75 [0.96, 7.86] 0.06 7.31 [1.94, 27.58] <0.01   Slow/Normal (n=114) 1.39 [0.53, 3.59] 0.50 1.44 [0.50, 4.12] 0.50 1.69 [0.38, 7.60] 0.49   Slow/Slow (n=253) 3.88 [1.91, 7.91] <0.01 2.36 [1.02, 5.46] 0.045 3.89 [1.14, 13.27] 0.03 Model 2: Gait speed change   Baseline to 1 year per 0.1m/s increase 0.83 [0.74, 0.92] <0.01 0.92 [0.80, 1.04] 0.19 0.75 [0.64, 0.88] <0.01

Conclusion

These data reveal there is marked heterogeneity in the trajectory of physical function after TAVI and that this trajectory–more so than baseline physical function–is clinically consequential. Identifying and optimizing factors associated with physical resilience after TAVI may improve outcomes.

P4666Higher BNP levels after transcatheter aortic valve implantation are associated with increased mortality and hospitalizations

Background

Among patients with aortic stenosis (AS), the adverse association between increased B-type natriuretic peptide (BNP) levels and worse clinical outcomes, including mortality and hospitalization after valve replacement, has been demonstrated. However, little attention has been paid to the clinical consequences of BNP levels after valve replacement, which may have implications for medical therapy prescribed after the procedure.

Purpose

Evaluate the association between BNP levels after transcatheter aortic valve implantation (TAVI) and subsequent mortality and hospitalizations.

Methods

Among intermediate, high, and extreme risk patients with severe symptomatic AS who received TAVI for native valve AS in the PARTNER II and S3 clinical trials or registries, we included 3260 patients who had BNP measured at baseline. Patients from sites which measured NTproBNP were excluded. To account for factors that influence BNP levels, we developed a regression equation–including age, sex, BMI, creatinine, study site, and the upper limit of normal of the BNP assay used for a given measurement–to determine expected BNP. BNP ratio was determined pre-TAVR and at discharge, 30 days, and 1 year and calculated as the actual BNP/expected BNP. Using a landmark approach, the relationships between (1) BNP ratio at 30 days or (2) delta BNP ratio between discharge and 30 days and subsequent outcomes between 30 days and 1 year were assessed. The primary outcome was a composite of cardiovascular (CV) mortality or hospitalization. Adjustment was made for 20 baseline and post-procedural factors known to influence outcomes.

Results

Higher BNP ratio at 30 days was associated with higher CV mortality or hospitalization between 30 days and 1 year (adjusted hazard ratio [aHR] 1.07 per increase of 1 in the BNP ratio, 95% CI 1.04–1.10, p<0.001), whereas baseline BNP ratio was not (p=0.38). A similar relationship was shown for the components of this composite: CV mortality (aHR 1.08, 95% CI 1.04–1.12, p<0.001) and hospitalizations (aHR 1.04, 95% CI 1.01–1.08, p=0.01). Adjusted for discharge BNP ratio and other factors, a greater decrease in BNP ratio between discharge and 30 days was also associated with lower CV mortality or hospitalization between 30 days and 1 year (aHR 0.95 per decrease of 1 in the BNP ratio, 95% CI 0.92–0.99, p=0.006). Similar relationships were observed for all-cause mortality and when examining the relationship between 1 year BNP ratio and outcomes between 1 and 2 years.

Conclusion

Higher BNP ratio after TAVI is associated with higher subsequent all-cause and CV mortality and hospitalizations, whereas baseline BNP ratio was not. Greater decrease in BNP ratio between discharge and 30 days is associated with better outcomes. Further investigation is warranted to understand these findings and determine whether intensification of medical therapy to decrease BNP after TAVR may improve patient outcomes.

Stability of Vaccines

Vaccines are considered the most economical and effective preventive measure against most deadly infectious diseases. Vaccines help protect around three million lives every year, but hundreds of thousands of lives are lost due to the instability of vaccines. This review discusses the various types of instability observed, while manufacturing, storing, and distributing vaccines. It describes the specific stability problems associated with each type of vaccine. This review also discusses the various measures adopted to overcome these instability problems. Vaccines are classified based on their components, and this review discusses how these preventive measures relate to each type of vaccine. This review also includes certain case studies that illustrate various approaches to improve vaccine stability. Last, this review provides insight on prospective methods for developing more stable vaccines.

The World Health Organization Measles Programmatic Risk Assessment Tool-Pilot Testing in India, 2014

Measles is a leading cause of child mortality, and reduction of child mortality is a key Millennium Development Goal. In 2014, the World Health Organization and the U.S. Centers for Disease Control and Prevention developed a measles programmatic risk assessment tool to support country measles elimination efforts. The tool was pilot tested in the State of Uttarakhand in August 2014 to assess its utility in India. The tool assessed measles risk for the 13 districts of Uttarakhand as a function of indicator scores in four categories: population immunity, surveillance quality, program delivery performance, and threat. The highest potential overall score was 100. Scores from each category were totaled to assign an overall risk score for each district. From this risk score, districts were categorized as low, medium, high, or very high risk. Of the 13 districts in Uttarakhand in 2014, the tool classified one district (Haridwar) as very high risk and three districts (Almora, Champawat, and Pauri Garhwal) as high risk. The measles risk in these four districts was largely due to low population immunity from high MCV1-MCV2 drop-out rates, low MCV1 and MCV2 coverage, and the lack of a supplementary immunization activity (SIA) within the past three years. This tool can be used to support measles elimination in India by identifying districts that might be at risk for measles outbreaks, and to guide risk mitigation efforts, including strengthening routine immunization services and implementing SIAs.

Association of acute toxic encephalopathy with litchi consumption in an outbreak in Muzaffarpur, India, 2014: a case-control study

BACKGROUND

Outbreaks of unexplained illness frequently remain under-investigated. In India, outbreaks of an acute neurological illness with high mortality among children occur annually in Muzaffarpur, the country's largest litchi cultivation region. In 2014, we aimed to investigate the cause and risk factors for this illness.

METHODS

In this hospital-based surveillance and nested age-matched case-control study, we did laboratory investigations to assess potential infectious and non-infectious causes of this acute neurological illness. Cases were children aged 15 years or younger who were admitted to two hospitals in Muzaffarpur with new-onset seizures or altered sensorium. Age-matched controls were residents of Muzaffarpur who were admitted to the same two hospitals for a non-neurologic illness within seven days of the date of admission of the case. Clinical specimens (blood, cerebrospinal fluid, and urine) and environmental specimens (litchis) were tested for evidence of infectious pathogens, pesticides, toxic metals, and other non-infectious causes, including presence of hypoglycin A or methylenecyclopropylglycine (MCPG), naturally-occurring fruit-based toxins that cause hypoglycaemia and metabolic derangement. Matched and unmatched (controlling for age) bivariate analyses were done and risk factors for illness were expressed as matched odds ratios and odds ratios (unmatched analyses).

FINDINGS

Between May 26, and July 17, 2014, 390 patients meeting the case definition were admitted to the two referral hospitals in Muzaffarpur, of whom 122 (31%) died. On admission, 204 (62%) of 327 had blood glucose concentration of 70 mg/dL or less. 104 cases were compared with 104 age-matched hospital controls. Litchi consumption (matched odds ratio [mOR] 9·6 [95% CI 3·6 - 24]) and absence of an evening meal (2·2 [1·2-4·3]) in the 24 h preceding illness onset were associated with illness. The absence of an evening meal significantly modified the effect of eating litchis on illness (odds ratio [OR] 7·8 [95% CI 3·3-18·8], without evening meal; OR 3·6 [1·1-11·1] with an evening meal). Tests for infectious agents and pesticides were negative. Metabolites of hypoglycin A, MCPG, or both were detected in 48 [66%] of 73 urine specimens from case-patients and none from 15 controls; 72 (90%) of 80 case-patient specimens had abnormal plasma acylcarnitine profiles, consistent with severe disruption of fatty acid metabolism. In 36 litchi arils tested from Muzaffarpur, hypoglycin A concentrations ranged from 12·4 μg/g to 152·0 μg/g and MCPG ranged from 44·9 μg/g to 220·0 μg/g.

INTERPRETATION

Our investigation suggests an outbreak of acute encephalopathy in Muzaffarpur associated with both hypoglycin A and MCPG toxicity. To prevent illness and reduce mortality in the region, we recommended minimising litchi consumption, ensuring receipt of an evening meal and implementing rapid glucose correction for suspected illness. A comprehensive investigative approach in Muzaffarpur led to timely public health recommendations, underscoring the importance of using systematic methods in other unexplained illness outbreaks.

Outbreaks of unexplained neurologic illness - Muzaffarpur, India, 2013-2014

Outbreaks of an unexplained acute neurologic illness affecting young children and associated with high case-fatality rates have been reported in the Muzaffarpur district of Bihar state in India since 1995. The outbreaks generally peak in June and decline weeks later with the onset of monsoon rains. There have been multiple epidemiologic and laboratory investigations of this syndrome, leading to a wide spectrum of proposed causes for the illness, including infectious encephalitis and exposure to pesticides. An association between illness and litchi fruit has been postulated because Muzaffarpur is a litchi fruit-producing region. To better characterize clinical and epidemiologic features of the illness that might suggest its cause and how it can be prevented, the Indian National Centre for Disease Control (NCDC) and CDC investigated outbreaks in 2013 and 2014. Clinical and laboratory findings in 2013 suggested a noninflammatory encephalopathy, possibly caused by a toxin. A common laboratory finding was low blood glucose (<70 mg/dL) on admission, a finding associated with a poorer outcome; 44% of all cases were fatal. An ongoing 2014 investigation has found no evidence of any infectious etiology and supports the possibility that exposure to a toxin might be the cause. The outbreak period coincides with the month-long litchi harvesting season in Muzaffarpur. Although a specific etiology has not yet been determined, the 2014 investigation has identified the illness as a hypoglycemic encephalopathy and confirmed the importance of ongoing laboratory evaluation of environmental toxins to identify a potential causative agent, including markers for methylenecyclopropylglycine (MCPG), a compound found in litchi seeds known to cause hypoglycemia in animal studies. Current public health recommendations are focused on reducing mortality by urging affected families to seek prompt medical care, and ensuring rapid assessment and correction of hypoglycemia in ill children.

Unusual Presentation of Necrotic Erythema Nodosum Leprosum on Scalp: A Case Report

Lepra reactions are acute episodes occurring during the disease process of leprosy and are of 2 types: type 1 or reversal reaction and type 2 reaction or erythema odosumleprosum (ENL). In the episodes of lepra reaction several parts are affected including face and extremities like oral cavity. In the present case report we reported a rare case of lepromatous leprosy with necrotic ENL involving scalp apart from the usual sites. A 58 year old married male presented to us with complaints of spontaneous onset, recurrent eruption of multiple reddish raised painful lesions. Biopsy from the infiltrated skin over the back showed atrophic epidermis, free Grenz zone, diffuse and periadnexal macrophage granulomas with predominant mononuclear infiltrate, appandageal atrophy, fibrosis around the neural structures and leukocytoclastic vasculitis. Fites stain showed strong positivity for M. leprae. His routine blood investigations showed anemia (Hb = 7.8 gm%), neutrophil leukocytosis (TLC = 17,600, DLC = P66L28M4E2) and raised ESR (80 mm in the first hour). These bullous and necrotic lesions in leprosy may be a manifestation of severe type II reactions in patients with very high bacillary load.

Evaluation of serum prolactin level in patients of subclinical and overt hypothyroidism

BACKGROUND

Prolactin secretion is controlled by prolactin inhibitor factor that is secreted from hypothalamus; factors like vasoactive inhibitory peptide (VIP) and thyroid releasing hormone (TRH) lead to increase in prolactin secretion. Hyperprolactinemia is a common condition that can result from a number of causes including hypothyroidism. Objective of the study was to determine correlation between serum levels of prolactin and thyroid hormones in euthyroid, subclinical and overt hypothyroid cases.

MATERIALS AND METHODS

Consecutive patients presenting for various thyroid related problems were segregated into two groups subclinical and overt hypothyroidism according to their diagnosis based on history and clinical examination, laboratory reports, inclusion and exclusion criteria. Newly diagnosed 75 patients in each group were finally enrolled. Similar number of age and sex matched controls were selected. All subjects filled a predesigned questionnaire for the evaluation of hypothyroid symptoms. Thyroid profile for T3, T4 (total and free), TSH and prolactin were determined in all the subjects and analyzed.

RESULTS

Prolactin elevation was found in 16 patients (21.33 %) with overt hypothyroidism, and in six patients (8%) with subclinical hypothyroidism. The control group and subclinical hypothyroid patients exhibited no significant difference in terms of total and free T3, total and free T4. For TSH and prolactin on the other hand, a statistically significant elevation was found in patients with overt hypothyroidism when compared with subclinical hypothyroidism; and in patients with subclinical hypothyroidism when compared to the controls. A significant statistical difference was observed between the two groups of hypothyroid patients for all hypothyroid symptoms except alopecia and hirsuitism.

CONCLUSION

The incidence of hyperprolactinemia in hypothyroidism was found to be higher when compared with normal controls. Serum prolactin assessment should be performed on all patients with hypothyroidism (overt and subclinical) before performing further tests.

Cross-sectional Study to Acknowledge the Independent Association of the Socio-demographic Determinants of Alcohol Use in an Urban Slum of North India

BACKGROUND

To seek pleasure is man's innate nature. In his search for gratification, man has discovered a world of substances that intoxicated him. Those who fell within its trap, their life changed, their families aggrieved and they shrank from company. The addiction remained alone in the end. To many death was a relief.

METHODS

A community based cross- sectional study was conducted in the Catchment area of UHTC (Urban Health and training Centre) where all males aged ≥15 years residing in the study area were included. Data was collected by home visit using WHO questionnaire (

AUDIT

Alcohol use disorder identification test) Modified Kuppuswamy scale was used to assess the socio-economic status of the families. Data was analyzed by appropriate test using SPSS 20.0 version. Logistic regression was applied to the positively associated results.

RESULTS

According to the AUDIT score, Hazardous, Dependent and harmful drinkers were 7.7%, 9.2% and 2.4% respectively. Age, marital status, education of the head of the family, occupation of the respondent, caste, family history of alcohol use had statistically significant association (P < 0.05, 95% confidence interval). Logistic regression was applied and marital status, family history of alcohol use and caste retained their statistical significance (P < 0.05, 95% confidence interval).

CONCLUSIONS

It can be concluded that being young, being low educated, being married and having a family history of alcohol use are more at risk to it. This indicates the dire necessity to consider the above factors in order to combat with this evil of alcohol use.

Electroconvulsive therapy pre-treatment with low dose propofol: comparison with unmodified treatment

BACKGROUND

Whilst electroconvulsive therapy (ECT) is routinely administered under anesthesia in developed nations, in many developing countries, ECT is still administered unmodified. This practice has attracted considerable scrutiny with calls to ban unmodified ECT. However, there are no affordable alternatives for many poor, acutely ill psychiatric patients. We evaluated whether administration of intravenous propofol 0.5 mg/kg for sedation by the ECT psychiatrist just prior to otherwise unmodified treatment improved acceptance of and reduced anxiety surrounding the treatment.

METHOD

We conducted an open label trial at The King George's Medical University in Lucknow, India. Forty-nine patients received propofol pre-treatment and 50 patients received unmodified treatment as usual.

RESULTS

Socio-demographic profiles, diagnoses and clinical responses were comparable. Patients who received propofol experienced less anxiety monitored by the State-Trait Anxiety Inventory just prior to ECT (p < 0.001), and had a more favorable attitude towards treatment assessed by an established questionnaire (Freeman and Kendell, 1980). Propofol patients were less likely to experience post-ictal delirium monitored by the CAM-ICU (p = 0.015) and had fewer cognitive side-effects on the MMSE (p = 0.004). There were no adverse events associated with propofol administration.

CONCLUSION

Whilst unmodified ECT should never be used when modified ECT under anesthesia is available, we have found low dose propofol can be safely administered by the ECT psychiatrist to sedate patients pre-treatment who would otherwise receive completely unmodified treatment. The intervention was associated with reduced anxiety and a more positive attitude towards ECT, without compromising efficacy. A randomized double blind controlled study is necessary to confirm these benefits.

Lepromatous leprosy with an uncommon presentation: a case report

28 yr old male presented with asymptomatic nodules and few well to ill defined papules on ears, asymmetrical nerve enlargement and evanescent tender nodules on the extremities without any infiltration of the skin and madarosis. Slit skin smear done from normal skin was BI 6+. Skin biopsy showed features of lepromatous leprosy.

Interrelationship between Diabetes and Periodontitis- A Review

Evidence for the link between periodontal disease and several systemic diseases is growing rapidly. Diabetes mellitus is a systemic disease with several major complications affecting both the quality and length of life causing morbidity and mortality. Periodontitis, one of these complications, is a chronic infection associated with substantial morbidity in the form of tooth loss and that affects the quality of life directly. The association between diabetes and inflammatory periodontal disease has been studied extensively. The relationship between these two conditions appears bidirectional. The presence of one condition tends to promote the other and the meticulous management of either may assist treatment of the other. It also provides a perfect example of a cyclical association, whereby a systemic disease predisposes the individual to oral infections, and once the oral infection is established, it exacerbates the systemic disease. This review focuses to explain the interrelationship between the two based on information in the literature and the potential common immunoregulatory connections involved, exploring the mechanisms through which periodontal infection can contribute to the low-grade general inflammation associated with diabetes. Keywords: Diabetes mellitus; inflammation; insulin resistance; periodontitis.

Knowledge, attitude, and practice of sugarcane crushers towards hand injury prevention strategies in India

INTRODUCTION

Injuries of the hand have an enormous impact on hand function and on quality of life. Occupational injuries are a major cause of morbidity and mortality in India and their incidence has been steadily increasing. Sugarcane crushers produce juice using dangerous procedures.

OBJECTIVE

The objective of this study was to determine the knowledge, attitudes, and practices among sugarcane crushers in India and thus assist in the formulation of effective preventive strategies.

SETTING

A block (area) in the Vellore District, South India (population 100 000).

SUBJECTS AND METHODS

All sugarcane crushers living in this area (n = 32) were included. A single observer, using a questionnaire, conducted personal on-site interviews.

RESULTS

Carelessness was involved in 63% of injuries. Sixteen per cent felt that machines with improved safety features are required; 40% supported the use of special gloves, although 19% considered them a hindrance. Eighty eight per cent did not consider the long duration of work as a risk factor and 38% were fatalistic (God's will); 50% thought the injuries were due to "bad luck".

CONCLUSION

Sugarcane crushers do not perceive the need for safer equipment. To overcome fatalistic views, and persuade this group to take other safety measures, safety education will need to take into consideration their socioeconomic and educational status.
