Effects of corruption and income inequality on the reported number of COVID-19 cases and deaths: Evidence from a time series cross-sectional data analysis.

Corruption-income inequality nexus is likely to affect the healthcare services, which in turn affect a country's ability to suppress an epidemic. Widespread corruption in public sectors may influence the data inventory practices to control the recording and sharing of official statistics to avoid political disturbance or social problems caused by an epidemic. This empirical study examines the effects of income inequality, data inventory, and universal healthcare coverage on cross-country variation in reported numbers of COVID-19 cases and deaths in the presence of corruption in public sectors. Daily numbers of COVID-19 cases and deaths of selected 29 countries are integrated for the first 120 days of the epidemic in each country. COVID-19 dataset is then integrated with a dataset of different indices. Fixed effect panel model is applied to explore the effects of corruption perception, income inequality, open data inventory practice, and universal health coverage on the daily numbers of COVID-19 cases and deaths per million. Income inequality, corruption perception and open data inventory are found to significantly affect the number of confirmed cases and deaths. Countries with alarming income inequality are found to report 39.89 more COVID-19 cases per million, on average. Under a lower level of corruption, countries with lower level of open data inventory are expected to report 74.31 more COVID-19 cases but 1.43 less deaths per million. Given a higher level of corruption, countries with lower level of open data inventory are expected to report lower number of COVID-19 cases and deaths. Corruption demonstrates a significant influence on the size of the epidemic in terms of the number of COVID-19 cases and deaths. A country with higher level of corruption in public sector along with lower levels of open data inventory is expected to report lower number of COVID-19 cases and deaths.

Genetic diversity of Lathyrus sp collected from different geographical regions.

BACKGROUND: The demand for grass peas (Lathyrus sativus L.) had increased as high nutritional safe food, but most of the accessions of South Asia and Africa had low grain harvest. Therefore, this study had been undertaken to collect grass pea germplasm for boosting yields and quality improvement. METHODS AND RESULTS: In this study, 400 accessions of grass pea from different geographical regions had characterized by using 56 Simple Sequences Repeat (SSRs) markers. In total 253 alleles were detected, the maximum and minimum polymorphic information content (PIC) indices were 0.70 and 0.34 found in markers G17922 and G18078, correspondingly. The germplasm was split into two main and one sub-group by cluster assay, by SSR assay, and three populations by model-based population structure analysis (Pop1, Pop2 and admixed). Neighbors joining tree assay showed the tested germplasm highly diverse in structure. Three-dimensional principal components analysis (PCA) and two dimensional principles coordinate analysis (PCoA) exhibited two main and one admixed group (P1, P2 and P1P2). In addition, FST population value of pairwise mean and analysis of molecular variance (AMOVA) showed high population structure across all pairs of populations on an average 0.1710 advocating all population structure categories varied significantly. The average predictable heterozygosity distant was 0.4472-0.4542 in same cluster for the individuals. CONCLUSION: Discovery from this study revealed SSR markers based polymorphic bands showed in the diversified grasspea germplasm which might be utilized as genetic resource of a breeding scheme and prospective uses for mapping analyses of recombinant inbred lines (RIL).

Genetic diversity analysis for narrow-leafed lupin (Lupinus angustifolius L.) by SSR markers.

Narrow-leafed lupin (Lupinus angustifolius L.) is used as grain legumes, fodder for livestock and green manure in the world and has a great potential to be developed as a new crop in China. In this study, we assessed the genetic diversity among a set of 109 newly introduced accessions of narrow-leafed lupin using 76 genomic SSR markers. Data analysis suggested that the average gene diversity index and average polymorphism information content (PIC) were 0.4758 and 0.4328, respectively. The mean allele number per loci (Na) was 6.3816. The population structure analysis identified two subgroups based on delta K (ΔK) values. This result is in accordance with that of a PCA. The AMOVA analysis showed that most of molecular variance were within population. These results will be useful to guide the genetic improvement of the narrow-leafed lupin crop in China.

Bullying victimization and adverse health behaviors among school-going adolescents in South Asia: Findings from the global school-based student health survey.

BACKGROUND: Bullying among adolescents is a global public health issue and has adverse behavioral and mental health consequences, yet a little is known about the relationship between bullying victimization and adverse health behaviors in adolescence in South Asian countries. METHODS: Data for this cross-sectional analysis were extracted from the global school-based student health survey (GSHS) in Bangladesh (n = 2,989), 2014 and in Nepal (n = 6,529), 2015. Multivariate logistic regression analyses were used to identify the associations between bullying victimization and adverse health behaviors or outcomes: physical violence, sexual history, tobacco use, alcohol use, drug use, suicide ideation, plan, attempt, loneliness, and sleeping difficulty. RESULTS: The prevalence of bullying victimization that occurred for a minimum of 1 day during the 30 days preceding the survey was 24.5% in Bangladesh and 50.9% in Nepal. This study observed significant relationships between bullying victimization and several adverse health behaviors/outcomes. For example, in Bangladesh, the odds of attempted suicide were found to be higher in adolescents that experienced bullying for 1-2 (adjusted odds ratio [AOR]: 2.92; 95% confidence interval [CI]: 1.64-5.19), 3-5 (AOR: 3.55; 95% CI: 1.69), 6-9 (AOR: 5.33; 95% CI: 1.24-22.77), or 10 days or more (AOR: 9.83; 95% CI: 4.17-23.16) during the 30 days preceding the survey than who did not. CONCLUSIONS: Bullying among adolescents in school is common in Bangladesh and Nepal and is associated with several adverse health behaviors. Bullying and its potential health consequences are needed to be addressed in health promotion and programs in these countries.

The double burden of under- and overnutrition among Bangladeshi women: Socioeconomic and community-level inequalities.

BACKGROUND: The prevalence of overweightness in Bangladesh is increasing, while underweightness also continues to persist. A better understanding of the patterns and socioeconomic risk factors of both conditions, particularly among women, is critical in order to promote the development of interventions to improve maternal health in Bangladesh. This study therefore sought to assess the patterns of under- and overweightness between 2004 and 2014 and to examine the predictors of individual and community-level inequalities of under- and overnutrition in Bangladesh. METHODS: Cross-sectional data of 10, 431, and 16,478 ever-married nonpregnant women aged between 15 and 49 years who did not give birth in the two months preceding the survey were extracted from the 2004 and 2014 Bangladesh Demographic and Health Surveys, respectively. Body mass index was used to measure weight status, and underweightness, at-risk for overweightness, overweightness, and obesity were the main outcome variables. Patterns of nutritional change over time was examined by considering the annual average rate of change. Multilevel multinomial logistic regression and quantile regression were used to identify the inequalities. RESULTS: In 2014, the age-adjusted prevalence values of underweightness, at-risk for overweightness, overweightness, and obesity were 19.7%, 14.9%, 18.1% and 4.0%, respectively. A higher average annual rate of reduction of underweightness was found among wealthier, highly educated, and wealthier community-living women, while a rate of increase of overweightness was found among poorer, uneducated, and poor community-living women. Individual and community-level inequalities of malnutrition were observed among these populations. In comparison with women living in low wealth communities, women from wealthier communities were at an increased risk of being at-risk for overweightness [adjusted odds ratio (AOR): 1.53, 95% confidence interval (CI): 1.23-1.91], overweight (AOR: 1.60, 95% CI: 1.27-2.00), and obese (AOR: 2.12, 95% CI: 1.42-3.18). CONCLUSIONS: This study suggests the coexistence of a double burden of under- and overnutrition in Bangladesh and that the prevalence of overweightness surpasses that of underweightness. The burdens of under- and overnutrition are strongly associated with women's individual socioeconomic positions and the nature of the community in which they live.

Reduction of cadmium toxicity in wheat through plasma technology.

Cadmium (Cd) contamination in plant-derived food is a big concern. This study examines whether and how Ar/O2 and Ar/Air plasma techniques lead to Cd detoxification in wheat. Treatment with Ar/O2 and Ar/Air changed the seed surface and decreased the pH of seeds as well as the cultivation media. Generally, plants subjected to Cd treatment from seeds treated with Ar/O2and Ar/Air plasma showed considerable progress in morphology and total chlorophyll synthesis compared to Cd-treated wheat, suggesting that plasma technology is effective for Cd detoxification. Furthermore, Ar/O2 and Ar/Air plasma treated plants showed a significant decrease in root and shoot Cd concentration, which is consistent with the reduced expression of Cd transporters in the root (TaLCT1 and TaHMA2) compared with the plants not treated with plasma in response to Cd stress. This Cd inhibition is possibly accomplished by the decrease of pH reducing the bioavailability of Cd in the rhizosphere. These observations are in line with maintenance of total soluble protein along with reduced electrolyte leakage and cell death (%) in root and shoot due to Ar/O2 and Ar/Air treatments. Further, Cd-induced elevated H2O2 or oxidative damage in tissues was mainly diminished through the upregulation of antioxidant enzymes (SOD and CAT) and their corresponding genes (TaSOD and TaCAT) induced by Ar/O2 and Ar/Air plasma. Grafting results suggest that root originating nitric oxide signal possibly drives the mechanisms of Cd detoxification due to plasma treatment in wheat. These findings provide a novel and eco-friendly use of plasma technology for the mitigation of Cd toxicity in wheat plants.

Mechanisms and Signaling Associated with LPDBD Plasma Mediated Growth Improvement in Wheat.

This study investigates the effect and mechanisms of low pressure dielectric barrier discharge (LPDBD) produced with Ar/O2 and Ar/Air technique causing biological stimulation leading to improved germination and growth in wheat. Both plasma treatments caused rougher and chapped seed surface along with noticeable improvement in seed germination in wheat. Beside this, seed H2O2 concentration significantly increased compared to controls subjected to Ar/O2 and Ar/Air while this phenomenon was more pronounced due to Ar/Air plasma. Analysis of plants grown from the plasma treated seeds showed significant improvement in shoot characteristics, iron concentration, total soluble protein and sugar concentration in comparison with the controls more efficiently due to Ar/O2 plasma than that of Ar/Air. Further, none of the plasma treatments caused membrane damage or cell death in root and shoot of wheat. Interestingly, Ar/O2 treated plants showed a significant increase (2-fold) of H2O2 compared to controls in both root and shoot, while Ar/Air plasma caused no changes in H2O2. This phenomenon was supported by the biochemical and molecular evidence of SOD, APX and CAT in wheat plants. Plants derived from Ar/O2 treated seeds demonstrated a significant increase in SOD activity and TaSOD expression in roots of wheat, while APX and CAT activities along with TaCAT and TaAPX expression showed no significant changes. In contrast, Ar/Air plasma caused a significant increase only in APX activity in the shoot. This suggests that Ar/O2 plasma caused a slight induction in H2O2 accumulation without triggering the H2O2 scavengers (APX and CAT) and thus, efficiency affect growth and development in wheat plants. Further, grafting of control and Ar/O2 treated plants showed a significant increase in shoot biomass and H2O2 concentration in grafts having Ar/O2 rootstock regardless of the type scion attached to it. It indicates that signal driving Ar/O2 plasma mediated growth improvement in wheat is possibly originated in roots. Taken together, this paper delivers new insight into the mechanistic basis for growth improvement by LPDBD technique.

Prevalence and Determinants of Contraceptive use among Employed and Unemployed Women in Bangladesh.

BACKGROUND: Contraceptive use plays a significant role in controlling fertility, particularly in reaching the replacement level of fertility. The association between women's employment status and contraceptive use is poorly studied and understood in Bangladesh. The aim of this study was to determine the factors that influence contraceptive use among employed and unemployed women in Bangladesh. METHODS: Data and necessary information of 16,616 married women were extracted from the Bangladesh Demographic and Health Survey (BDHS) 2011. The cross sectional data has been used for univariate analysis, to carry out the description of the variables; bivariate analysis, to find the associations among the variables; and binary logistic regression analysis, to evaluate the effects of selected sociodemographic factors on contraceptive use. RESULTS: The results revealed that the contraceptive use was found higher among employed women (67%) than that of unemployed women. Women's age, education, region, number of living children, and child preference were found to be significantly associated with current use of contraception among employed women. On the other hand, women's age, education, husband's education, region, residence, religion, number of living children, ever heard about family planning, and child preference were identified as the significant predictors of contraceptive use among unemployed women. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: A gap in using contraceptives among employed and unemployed women is identified. By creating employment opportunities for women to be enhanced the contraceptive use. Moreover, the sociodemographic factors need to be taken into consideration in formulating policies and implementing programs to increase the contraceptive prevalence rate among women.

Factors affecting the utilisation of postpartum care among young mothers in Bangladesh.

This article addresses the hypothesis that predisposing, enabling and need factors of households influence utilisation of postpartum care among the young mothers according to the timing and type of providers. To reach our goal Bangladesh Demographic and Health Survey of 2007 data (n = 2376) were used. Findings revealed that only one-third of the young mothers received postpartum care. Postpartum care by medically trained personnel and within the most critical period (within 48 h after delivery) was found to be very low (25.5 and 16.6%). Regarding postpartum morbidities, only one-fifth to one-half of the women reporting a complication consulted medically trained providers. Indeed, between one third and two thirds did not seek any postpartum care. The highest percentages contacting healthcare providers were for convulsions and the lowest was when the baby's hands or feet came first. The stronger influence of the mother's education and antenatal care on the utilisation of postpartum care is consistent with findings from other studies. Concern of the husband or family about pregnancy complications showed a significant and positive impact on the utilisation of postpartum care. Multivariate analysis showed that mother's age at delivery, residence, education, antenatal care, place of delivery, wealth, husband's occupation, husband's concern about pregnancy complications and mother's permission to go to a health centre alone were likely to affect utilisation of postpartum care services. The results indicate urgent needs in Bangladesh for an awareness-raising program highlighting the importance and availability of postpartum care; for strategies to improve the availability and accessibility of antenatal care services and skilled birth attendance, including focused financial support; for women's education to be given high priority; and to enable women to exercise their rights to control their freedom of movement, own health care and access to economic resources.
