Abstract Introduction: Hypertension (HTN) is a public health problem. The prevalence and mortality rates are significantly higher in middle and low-income countries, such as Peru. This study aimed to determine the trend of mortality attributable to HTN for the 2005-2016 period in Peru. Methods: We conducted a secondary analysis based on death certificates provided by the Ministry of Health. We applied linear regression models to test the HTN mortality rate trend. Results: The age-standardized HTN mortality per 100,000 inhabitants decreased from 14.43 for the 2005 to 2010 period to 11.12 for the 2011 to 2016 period. The coast was the natural region with the highest decrease in mortality rate. Moreover, Tumbes, Callao, and Lambayeque were regions with the highest decline in mortality rate. Conclusion: The age-standardized mortality attributable to HTN decreased in Peru, with variations in both natural and political regions of the country.

Abstract Background Bullying and suicidal behaviors are a silent public health problem among adolescents. Little is known about the link between bullying and suicidal behaviors in low-income countries such as Tanzania. In the current study, we estimated the prevalence of being bullied and determined its association with suicidal behaviors among in-school adolescents. Methods We performed a secondary analysis of the Tanzania Global School-based Student Health Survey (GSHS) conducted in 2014. This was the first nationally representative survey conducted to a sample of 3793 in-school adolescents. The primary independent variable was being bullied, while the outcome variables of interest were suicide ideation and suicide attempt. We used a chi-square χ2 test for group variables comparisons and multivariate logistic regression for statistical associations between independent and outcome variables. In our analysis, a p < 0.05 was considered statistically significant at 95% confidence intervals. Results The prevalence of being bullied among 3793 surveyed in-school adolescents was 27.0%. In an adjusted multivariate regression model, being bullied was independently associated with suicidal ideation and suicide attempt: [AOR; 1.9, 95% C.I; 1.5–2.4], and [AOR; 3.6, 95% C.I; 2.9–4.5] respectively, p < 0.001. Conclusions Bullying is prevalent and possibly a potential predictor of suicidal behaviors among in-school adolescents in Tanzania. There is a need for all educational stakeholders: teachers, parents, students, mental health professionals, and policymakers to design a program for mitigating the problem of bullying in schools.

Rotavirus is the leading cause of severe acute childhood gastroenteritis, responsible for more than 128,500 deaths per year, mainly in low-income countries. Although the mortality rate has dropped significantly since the introduction of the first vaccines around 2006, an estimated 83,158 deaths are still preventable. The two main vaccines currently deployed, Rotarix and RotaTeq, both live oral vaccines, have been shown to be less effective in developing countries. In addition, they have been associated with a slight risk of intussusception, and the need for cold chain maintenance limits the accessibility of these vaccines to certain areas, leaving 65% of children worldwide unvaccinated and therefore unprotected. Against this backdrop, here we review the main vaccines under development and the state of the art on potential alternatives.

Abstract Background: Tuberculosis (TB) is a global public health problem, with the highest burden occurring in low-income countries, wherein the use of more sensitive diagnostics, such as Xpert MTB/RIF (GeneXpert), is still limited by costs. Testing of pooled samples from various individuals has been thought and thus investigated as a cost saving strategy to diagnose some diseases including TB. Then in cases where a pool is positive, retesting of the individual samples in that pool is done to identify the positive sample. We assessed the utility of a pooled testing strategy to optimize the affordability of GeneXpert for the diagnosis of TB Mwanza Tanzania. Methods: Remainder of samples from presumptive TB patients submitted for routine TB diagnosis were used for pooled samples (5 per pool) testing. The agreement of the results between individual sample testing against pooled samples testing and cost-effectiveness were assessed.Results: A total of 250 individual routinely submitted samples for TB diagnosis were tested using the established protocols. The median age of study participants was 35 [IQR 27 – 40] years and 143 (57.2%) were males. Of the 250 samples, 28 (11.2%) were detected to have MTB whereas 222 (88.8%) samples, were negative. Of the 50 sputum pools made, MTB were detected in 17 (34.0%) pools. Following retesting of these 17 positive pools, all 28 (100%) individual MTB samples were detected with the overall agreement being 100% (With the sensitivity of 100% and specificity of 100%). The number of individual MTB positive ranged from 1 to 3 per pool. Using pooling of sputum samples, the technique saved 115 (46.0%) of the cartridges in running 250 samples. This is equivalent to saving US$ 1147.7. Conclusion: The pooled sputum testing strategy reduced cartridge costs by 46.0%. The use of the pooled testing strategy reduces costs and has the potential to increase the affordability of GeneXpert testing in countries with limited resources. Pooled sputum for Xpert MTB/RIF can be used as an affordable diagnostic and/or screening tool in resource limited settings, such as Tanzania.

The role of forests as a reservoir for carbon has prompted the need for timely and reliable estimation of aboveground carbon stocks. Since measurement of aboveground carbon stocks of forests is a destructive, costly and time-consuming activity, aerial and satellite remote sensing techniques have gained many attentions in this field. Despite the fact that using aerial data for predicting aboveground carbon stocks has been proved as a highly accurate method, there are challenges related to high acquisition costs, small area coverage, and limited availability of these data. These challenges are more critical for non-commercial forests located in low-income countries. Landsat program provides repetitive acquisition of high-resolution multispectral data, which are freely available. The aim of this study was to assess the potential of multispectral Landsat 8 Operational Land Imager (OLI) derived texture metrics in quantifying aboveground carbon stocks of coppice Oak forests in Zagros Mountains, Iran. We used four different window sizes (3×3, 5×5, 7×7, and 9×9), and four different offsets ([0,1], [1,1], [1,0], and [1,-1]) to derive nine texture metrics (angular second moment, contrast, correlation, dissimilar, entropy, homogeneity, inverse difference, mean, and variance) from four bands (blue, green, red, and infrared). Totally, 124 sample plots in two different forests were measured and carbon was calculated using species-specific allometric models. Stepwise regression analysis was applied to estimate biomass from derived metrics. Results showed that, in general, larger size of window for deriving texture metrics resulted models with better fitting parameters. In addition, the correlation of the spectral bands for deriving texture metrics in regression models was ranked as b4>b3>b2>b5. The best offset was [1,-1]. Amongst the different metrics, mean and entropy were entered in most of the regression models. Overall, different models based on derived texture metrics were able to explain about half of the variation in aboveground carbon stocks. These results demonstrated that Landsat 8 derived texture metrics can be applied for mapping aboveground carbon stocks of coppice Oak Forests in large areas.

Prevalence data on severe dental infections is scarce, particularly for low-income countries. Patients with dental abscess complications who presented from September 2020 until December 2020 in two hospitals in Tonkolili District, Sierra Leone, were included into this case series. We report on a total of 20 patients, median age 28 years, with severe complications of dental abscesses, with a mortality rate of 45%. This case series illustrates the severity of the dire consequences of the absence of access to basic dental and oral healthcare.

Abstract This article analyzes cross-national trends in national student-faculty ratios (SFRs) over the past five decades. In descriptive analyses, we find that SFRs have increased globally, driven by particularly large increases in low-income countries. We analyze two cross-national datasets to examine factors associated with national SFRs. We find that national SFRs are positively associated with gross tertiary enrollment rates and particularly so in low-income countries. In contrast, both the female share of faculty and research spending are associated with having lower national SFRs. The findings shed light on how national higher education systems are responding to massification pressures and suggest that differentiating faculty roles is one way that countries curb their rising SFRs as enrollments grow.

Compulsive Disorder

Background: Although cooccurrence of nonsubstance use disorders (non-SUDs) and substance use is well-established in the literature, most of what we know in this regard is derived from studies that have recruited predominantly White sample populations. As a result, there is a gap in knowledge on this link among low-income African Americans (AAs). There is also a need to understand how low-income AA men and women differ in these associations. Objective: To study whether there is an association between number of non-SUDs and amount of alcohol consumption by AA adults, and whether this association varies between AA men and women. Methods: This cross-sectional study recruited a nonrandom sample of 150 AA adults with non-SUDs (i.e., major depression, bipolar disorders, obsessive–compulsive disorder, paranoid disorder, panic disorder, posttraumatic stress disorder (PTSD), and schizoaffective disorder). The independent variable was the number of non-SUDs. The dependent variable was the amount of alcohol consumption. Age, socioeconomic status (educational attainment and household income), and self-rated health were covariates. Gender was the moderator. Linear regression models were used to analyze the data. Results: A higher number of non-SUDs was not associated with a higher amount of alcohol use in the pooled sample of AA adults. We, however, found a significant interaction between gender and number of non-SUDs on the amount of alcohol use, suggesting a stronger effect of non-SUDs on alcohol consumption in AA men than in AA women. Gender-stratified linear regression models showed a positive association between number of non-SUDs and amount of alcohol consumption in AA men but not in AA women. Conclusion: Non-SUDs impact alcohol use of AA men but not women. Future research should test whether AA men may have a higher tendency to turn to alcohol to regulate their emotions and cope with psychological pain due to multiple non-SUDs. The results also suggest that integration of services for SUDs and non-SUDs may be more relevant to provision of mental health services for AA men than AA women.

COVID-19 was first reported in Wuhan, Hubei Province of China a few months ago (December 2019) and had since become a major challenging public health problem for not only China but also many countries around the world. It was on March 11, 2020, characterized by WHO as a pandemic. The pandemic so far has killed more than 526,465 people and infected more than 11,046,917 people around the world as of 05 July 2020. Nigeria currently has 28,167 confirmed COVID-19 cases with 11,462 (40%) discharged, 16,071 (57%) currently receiving treatment at designated facilities across the country and unfortunately 634 (3%) deaths as at the time of writing this manuscript. As far as the authors are aware, there are little or no work carried out on the implications of COVID-19 on dental practices in Nigeria. Recently, COVID-19 was identified in saliva of infected patients and so transmission via aerosols and splatter generated during dental procedures is sure. To limit exposure, there was a need to avoid scheduling patients except for emergency dental care during this outbreak. This limitation on activities of the dental sector has a very huge impact on the economy of the sector as it has already resulted in serious monetary implications for dental practices worldwide. While dental practices in the high-income countries are getting help from their respective Government, those in the middle and low-income countries like Nigeria have been left to wallow in bankruptcy without support. The authors highly recommend that the Government of these neglected countries, step up and support dental practices that are on the brink of closing down due to the low turnout of patients to their practice during this outbreak.

The benefits of physical activity (PA) on children’s health and well-being are well established. However, many children do not meet the PA recommendations, increasing their risk of being overweight, obese, and non-communicable diseases. Environmental characteristics of homes and neighborhoods may constrain a child’s ability to engage in PA, but evidence is needed to inform country-specific interventions in understudied low-income countries. This study assessed the associations between parental-perceived home and neighbourhood, built environment characteristics, and moderate-to-vigorous physical activity (MVPA) among children in Kampala city, Uganda. In this cross-sectional study, data were obtained from 256 children (55.5% girls) aged between 10 and 12 years and their parents. Children’s MVPA was measured using waist-worn ActiGraph accelerometers. The environments were assessed using a valid self-reported parent survey. Linear regression models with standard errors (clusters) were used to analyze the relationship between environmental variables and children’s MVPA. Sex-specific relationships were assessed using sex-stratified models. Play equipment at home (β = -2.37, p <0.001; unexpected direction), residential density (β = 2.70, p<0.05), and crime safety (β = -5.29, p <0.05; unexpected direction) were associated with children’s MVPA. The sex-specific analyses revealed more inconsistent patterns of results with a higher perception of land use mix associated with less MVPA in girls (irrespective of school type attended), and higher perceptions of sidewalk infrastructure (β = -12.01, p <0.05) and walking and cycling infrastructure (β = -14.72, p <0.05) associated with less MVPA in girls attending public schools only. A better perception of crime safety was associated with less MVPA among boys and girls attending private schools (β = -3.80, p <0.05). Few environmental characteristics were related to children’s MVPA in Uganda, and findings were largely inconsistent, especially among girls. Future studies are needed to understand the ecological determinants of health-related PA behaviors among children in Uganda.

Abstract Background The Eastern Zone of the Tigray (Ethiopia) is inhabited by 900,000 people, 34% of whom are adolescents and young people between 10-24 years of age, who are easily influenced by the social and family context and are exposed to significant health risks associated with the earliness of their approach to sexual life. Nonetheless, even if a complete health service is available, the quality is often undermined by the lack of the so-called Youth-Friendly Corners (high confidentiality spaces reserved for young people), promoted internationally by WHO. The aim of the study is to evaluate the effectiveness of the program established in this zone by the Medical Collaboration Committee regarding the creation of friendly health services for adolescent and youth people (AYFHS), especially built for sex education, family planning, abortion, and sexual transmitted infection (STI) prevention. Methods The program “#Youths at the centre!” was implemented in 20 rural health centers in the North-East Tigray on April 2018. Data from these AYFHS were collected monthly in aggregated indicators, separated for gender and age class. Use of AYFHS during 2018 and 2019 was assessed using percentage and 95% confidence interval and the period of implementation of the project and centers' characteristics were analyzed to investigate differences in AYFHS utilization. Results A monthly mean of 6.04% (6.01% - 6.08%) of adolescents and young people utilized an AYHFS for any of its service; 0.03% accessed for counseling, diagnosis, and treatment of STI, 1.31% for family planning, 1.09% for delivery, and 0.05% for legal abortion. Lower level of utilization was observed in more remote health centers, despite a general increase across the study period. Conclusions This project shows the importance of providing friendly facilities dedicated to adolescents and youth in low-income countries, in order to increment the utilization of health services from this population, especially in rural contexts. Key messages In rural areas of Africa the risks associated with poor health information of young people and the earliness of the beginning of sexual life remain a Public Health problem. In low income countries the presence of high confidentially spaces for young people in the Health Services could increase their utilization, especially for sex education and family planning.
