Quantifying plastic waste generation in Aizawl city, India: waste management and its impact on human and environmental health

Plastic wastes in recent years have become a menace owing to population pressure and high demand of various plastic products in daily use. A study was conducted in Aizawl city of northeast India for a period of 3 years to quantify various types of plastic wastes. Our study found that a present plastic consumption of 13.06 g/capita/day although low when compared to developed countries continues; the generation will be doubled after a decade as the population is projected to double specially due to migration from rural areas. The plastic waste was contributed more by the high-income group of the population with a correlation factor of r = 0.97. Among the total plastic waste, packaging plastics contributed maximum with an average of 52.56% and carry bags among the packaging contribute maximum with 32.55% in the three sectors, namely, residential, commercial, and dumping sites. The result leads to a maximum contribution by the LDPE polymer with 27.46% among seven categories of polymers.

Cost-effectiveness of video-observed therapy for ambulatory management of active tuberculosis during the COVID-19 pandemic in a high-income country

OBJECTIVE

The coronavirus 2019 (COVID-19) pandemic caused suspension of directly observed therapy (DOT) for patients with active tuberculosis (TB). This study aimed to estimate the outcomes of pandemic-related DOT suspension and the cost-effectiveness of video-observed therapy (VOT) during the pandemic.

METHODS

A decision-analytic model was constructed to project outcomes of adult patients with active TB from the perspective of a US healthcare provider. Two model-based analyses were conducted: (1) before (with DOT) and during [with self-administered therapy (SAT)] the pandemic; and (2) VOT vs SAT during the pandemic. The primary outcome measures were direct medical costs and disability-adjusted life years (DALYs).

RESULTS

In the base-case analysis, care during the pandemic (with SAT) increased the cost (by US$285 per patient) and DALYs (by 0.2155 per patient) in comparison with DOT. Care with VOT reduced DALYs (by 0.4870) and costs (by US$1797) in comparison with SAT. On probabilistic sensitivity analysis, care during the pandemic (with SAT) increased DALYs in 100% of 10,000 simulations, and increased costs in 55.52% of instances. Care with VOT reduced DALYs and costs in 99.7% and 68.79% of instances, respectively. The probability of VOT being cost-effective was 99.4% at the willingness-to-pay threshold of 50,000 US$/DALY.

CONCLUSION

Suspension of DOT during the COVID-19 pandemic worsened treatment outcomes. VOT was found to be a cost-effective option for active TB care in an outpatient setting.

Effect of micronutrient supplements on low-risk pregnancies in high-income countries: a systematic quantitative literature review

OBJECTIVE

To assess the quantity and focus of recent empirical research regarding the effect of micronutrient supplementation on live birth outcomes in low-risk pregnancies from high-income countries.

DESIGN

A systematic quantitative literature review.

SETTING

Low-risk pregnancies in World Bank-classified high-income countries, 2019.

RESULTS

Using carefully selected search criteria, a total of 2475 publications were identified, of which seventeen papers met the inclusion criteria for this review. Data contributing to nine of the studies were sourced from four cohorts; research originated from ten countries. These cohorts exhibited a large number of participants, stable data and a low probability of bias. The most recent empirical data offered by these studies was 2011; the most historical was 1980. In total, fifty-five categorical outcome/supplement combinations were examined; 67·3 % reported no evidence of micronutrient supplementation influencing selected outcomes.

CONCLUSIONS

A coordinated, cohesive and uniform empirical approach to future studies is required to determine what constitutes appropriate, effective and safe micronutrient supplementation in contemporary cohorts from high-income countries, and how this might influence pregnancy outcomes.

Dollar for Dollar: Racial and ethnic inequalities in health and health-related outcomes among persons with very high income

Racial and ethnic disparities in health have been well-documented, and low SES is widely considered to be a driver of this relationship. However, the race-social class-health interrelationship is complex, as several studies have found race disparities between racial/ethnic minorities and whites at middle- income levels. Research on higher income persons is complicated by the lack of data for persons with incomes about $75,000. Most national datasets collect income data in categories with the highest income category being $75,000 and above. In our study, we examined racial/ethnic disparities in health status and behaviors among persons of very high income, reported income of $175,000 or above per year. Data are from the Medical Expenditure Panel Surveys (MEPS). Our findings revealed health disparities in 10 of the 16 health-related outcomes selected. African Americans were most dissimilar to whites at this income and with disadvantages on 6 health outcomes relative to whites. While results also showed some disparities for Asian Americans and Hispanic Americans relative to whites, these groups were advantaged, relative to whites on several health outcomes. Our findings indicate that income does not fully explain racial/ethnic disparities in health. Most public interventions are targeted to low income persons. However, public health interventions should target minority individuals of very high income as well, especially African Americans.
