Cost-effectiveness analysis of surgical masks, N95 masks compared to wearing no mask for the prevention of COVID-19 among health care workers: Evidence from the public health care setting in India.

BACKGROUND: Nonpharmacological interventions, such as personal protective equipment for example, surgical masks and respirators, and maintenance of hand hygiene along with COVID-19 vaccines have been recommended to reduce viral transmission in the community and health care settings. There is evidence from the literature that surgical and N95 masks may reduce the initial degree of exposure to the virus. A limited research that has studied the cost-effective analysis of surgical masks and N95 masks among health care workers in the prevention of COVID-19 in India. The objective of this study was to estimate the cost-effectiveness of N95 and surgical mask compared to wearing no mask in public hospital settings for preventing COVID-19 infection among Health care workers (HCWs) from the health care provider's perspective. METHODS: A deterministic baseline model, without any mask use, based on Eikenberry et al was used to form the foundation for parameter estimation and to estimate transmission rates among HCWs. Information on mask efficacy, including the overall filtering efficiency of a mask and clinical efficiency, in terms of either inward efficiency(ei) or outward efficiency(e0), was obtained from published literature. Hospitalized HCWs were assumed to be in one of the disease states i.e., mild, moderate, severe, or critical. A total of 10,000 HCWs was considered as representative of the size of a tertiary care institution HCW population. The utility values for the mild, moderate and severe model health states were sourced from the primary data collection on quality-of-life of HCWs COVID-19 survivors. The utility scores for mild, moderate, and severe COVID-19 conditions were 0.88, 0.738 and 0.58, respectively. The cost of treatment for mild sickness (6,500 INR per day), moderate sickness (10,000 INR per day), severe (require ICU facility without ventilation, 15,000 INR per day), and critical (require ICU facility with ventilation per day, 18,000 INR) per day as per government and private COVID-19 treatment costs and capping were considered. One way sensitivity analyses were performed to identify the model inputs which had the largest impact on model results. RESULTS: The use of N95 masks compared to using no mask is cost-saving of $1,454,632 (INR 0.106 billion) per 10,000 HCWs in a year. The use of N95 masks compared to using surgical masks is cost-saving of $63,919 (INR 0.005 billion) per 10,000 HCWs in a year. the use of surgical masks compared to using no mask is cost-saving of $1,390,713 (INR 0.102 billion) per 10,000 HCWs in a year. The uncertainty analysis showed that considering fixed transmission rate (1.7), adoption of mask efficiency as 20%, 50% and 80% reduces the cumulative relative mortality to 41%, 79% and 94% respectively. On considering ei = e0 (99%) for N95 and surgical mask with ei = e0 (90%) the cumulative relative mortality was reduced by 97% and the use of N95 masks compared to using surgical masks is cost-saving of $24,361 (INR 0.002 billion) per 10,000 HCWs in a year. DISCUSSION: Both considered interventions were dominant compared to no mask based on the model estimates. N95 masks were also dominant compared to surgical masks.

Multisystem Inflammatory Syndrome Associated With COVID-19 in Children (MIS-C): A Systematic Review of Studies From India.

BACKGROUND: With wide clinical spectrum, multisystem inflammatory syndrome associated with coronavirus disease 2019 (COVID-19) in children (MIS-C) is a relatively novel condition occurring weeks to months' post SARS-CoV-2 infection. The aim was to systematically review data on clinical features, laboratory parameters and therapeutics of MIS-C from India. Methods: This systematic review was done as per the PRISMA guidelines, and quality assessment was done using NIH tool for case-series. A systematic search through databases yielded studies whose data was pooled to calculate the mean frequencies with standard deviation using GraphPad software. RESULTS: Screening of 2548 articles published till December, 2021, yielded 11 case-series. World Health Organization case definition was used widely. There was a slight preponderance of males (57%), median (IQR) age was 7 (6,7) years, 63% (n=305) required intensive care unit admissions, and mortality rate was 10% (n=261). Clinical features included fever, mucocutaneous features (72%), and gastrointestinal problems (62%) in majority. Widely used treatment was corticosteroids (76%) and intravenous immunoglobulin (62%) with other options depending on patient's state. An increased level of inflammatory markers and derangement in other parameters corroborated with disease status. Kawasaki disease like features, not reported in many studies, ranged from 4-76% of patients. CONCLUSION: MIS-C presents with a wide spectrum clinical features, increased inflammatory markers and managed as per the disease course and presentation. Future studies monitoring the long-term effects of MIS-C are recommended.

Effect of Probiotics on the Frequency of CD4+ T-Cells in HIV-Infected Children and Adolescents: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Depletion of CD4+ T-cells in the gut-associated lymphoid tissue is the hallmark of HIV infection, with only partial restoration by potent antiretroviral therapy (ART). Gut dysbiosis, together with disruption of mucosal integrity contributes to chronic immune activation that further exacerbates the disease. Data from randomized controlled trials in pediatric HIV patients have indicated potential of probiotics in complementing routine ART in managing HIV-associated gastrointestinal complications. We have systematically extracted data from these trials and performed meta-analysis to quantify the effect of probiotics on CD4+ T-cell counts and any adverse events associated with their supplementation. METHODS: A systematic search through multiple databases yielded three studies that were pooled using fixed-effect model. Risk of bias assessment was done by the Cochrane risk of bias tool and publication bias was assessed by Egger's test. RESULTS: Included studies had moderate risk of bias and Egger's statistics revealed no publication bias (p > 0.05). Pooled analysis showed significant improvement in CD4+ T-cell counts, with mean difference, 123.92 (95% CI: 104.36-143.48), p < 0.0001, no heterogeneity (I2=0) among the included trials. Subgroup analysis also depicted improvement in CD4+ T-cell counts irrespective of treatment duration, in both ART naïve and treated patients. No adverse effects with probiotic consumption were reported. CONCLUSIONS: Probiotics supplementation led to an improvement in CD4+ T-cell counts among HIV-infected children with no observed adverse effects. Despite the inherent limitations of included studies, our systematic review would justify more well-designed, large-scale trials in children, which may guide pediatricians on whether to incorporate probiotics as an adjunct therapy to routine ART.

HIV infection is associated with a progressive decline of CD4+ T-cell numbers and increase in viral load. To keep the virus replication in check, patients need to take the antiretroviral therapy life-long, which is not without gastrointestinal discomfort. Probiotics have already shown multiple benefits ranging from reduction in diarrhea, nausea and bloating besides replenishment of CD4+ T-cells numbers. Based on this background information, we have compiled the data on probiotics among HIV-infected children. A pooled analysis from randomized clinical trials revealed significant improvement in CD4+ T-cell counts in HIV-infected children without any adverse effects. However, we recommend large and well-designed trials in future that would help in forming a concrete and high quality evidence in this context.

Role of environmental lead in the occurrence of anemia in Indian children: a systematic review and meta-analysis.

Exposure to lead among children, as well as adults, is a major global health issue. With diverse routes of exposure (e.g., food, air, and water) either environmentally or occupationally, lead among children can cause mild, moderate, to severe health complications in the later stages of life. The average blood lead level reported by CDC in 2021 is 3.5 µg/dL, and the level of blood lead toxicity is ≥ 10 µg/dL. In this study, we planned to systematically analyze the association between blood lead levels (BLLs) (≥ 10 µg/dL and < 10 µg/dL) and the risk of anemia (hemoglobin level < 11 g/dL) among Indian children aged between ≥ 1 and ≤ 18 years. An online literature search of 5 databases, PubMed, Ovid, EMBASE, Web of Science, and Google Scholar was accomplished with a search updated until 8th March 2021. Study designs included cohort, cross-sectional, and case-control studies that have evaluated the association of lead toxicity or exposure with anemia (Hb < 11 g/dL) reported in urban and/or rural Indian children. Meta-analysis was performed among a total of 864 children from 4 cross-sectional studies. The association between lead toxicity (BLLs ≥ 10 µg/dL) and the risk of being anemic was not statistically significant (RR = 1.15 (95% CI: 0.86-1.55, I2 = 77%). The risks of bias in all included studies were low according to the Newcastle Ottawa Scale. Increased blood lead levels did not appear to be the major contributor to anemia in Indian Children. We need to focus primarily on improving the nutritional quality, fortified food supplements, and a balanced diet for children to reduce the anemia burden in India. Lead toxicity should be sought as an etiological factor only in areas of high environmental risk factors which were leaded paints, leaded batteries, a house near major road/traffic areas, and pesticide exposure.

Evaluation of Tele-rheumatology during the COVID-19 Pandemic in Asian Population: A Pilot Study.

OBJECTIVE: Rheumatoid arthritis (RA) is a chronic autoimmune condition associated with a potential for deformities. It is one of the common conditions to seek health care. Hence, the present study was conducted to assess the telemedicine services for patients suffering from rheumatoid arthritis during the COVID-19 pandemic in an Asian Indian population. METHODS: A prospective study was conducted (March 2020-June 2020) in the telemedicine department of a premier northern Indian tertiary care institution. Out of the total patients enrolled (N = 7577) in telemedicine services, 122 rheumatoid arthritis patients (1.6%) were followed for 1 month to assess change in functional status by modified Health Assessment Questionnaire (mHAQ). Telephonic interviews of the enrolled patients were conducted to determine the level of understanding of advice given by consultants, barriers during the consultation, and satisfaction with teleconsultations for rheumatology clinics. RESULTS: For the native people, language of the clinicians was the main barrier (20%) in telerheumatology. Saving of time and money was observed as beneficial factors for patients. More than three-quarters of all rheumatoid arthritis patients were ready to use teleconsultation in the near future. A similar proportion of patients were in support for the recommendation of these services to other persons. CONCLUSION: We report the successful use of telemedicine services in the evaluation and management of rheumatic diseases in the current COVID-19 pandemic situation.
