Inequalities in access to water and soap matter for the COVID-19 response in sub-Saharan Africa
Authors: Jiwani Safia S. , Antiporta Daniel A. 
Published: June 2020

AbstractThe COVID-19 pandemic has spread rapidly since the first case notification of the WHO in December 2019. Lacking an effective treatment, countries have implemented non-pharmaceutical interventions including social distancing measures and have encouraged maintaining adequate and frequent hand hygiene to slow down the disease transmission. Although access to clean water and soap is universal in high-income settings, it remains a basic need many do not have in low- and middle-income settings.We analyzed data from Demographic and Health Surveys (DHS) of 16 countries in sub-Saharan Africa, using the most recent survey since 2015. Differences in the percentage of households with an observed handwashing place with water and soap were estimated by place of residence and wealth quintiles. Equiplots showed wide within-country disparities, disproportionately affecting the poorest households and rural residents, who represent the majority of the population in most of the countries.Social inequalities in access to water and soap matter for the COVID-19 response in sub-Saharan Africa. Interventions such as mass distribution of soap and ensuring access to clean water, along with other preventive strategies should be scaled up to reach the most vulnerable populations.

Abstract
Background
Indoor air pollution is an important risk factor for health in low- and middle-income countries.

Methods
We measured indoor fine particulate matter (PM2.5) and carbon monoxide (CO) concentrations in 617 houses across four settings with varying urbanisation, altitude, and biomass cookstove use in Peru, between 2010 and 2016. We assessed the associations between indoor pollutant concentrations and blood pressure (BP), exhaled carbon monoxide (eCO), C-reactive protein (CRP), and haemoglobin A1c (HbA1c) using multivariable linear regression among all participants and stratifying by use of biomass cookstoves.

Results
We found high concentrations of indoor PM2.5 across all four settings (geometric mean ± geometric standard deviation of PM2.5 daily average in μg/m3): Lima 41.1 ± 1.3, Tumbes 35.8 ± 1.4, urban Puno 14.1 ± 1.7, and rural Puno 58.8 ± 3.1. High indoor CO concentrations were common in rural households (geometric mean ± geometric standard deviation of CO daily average in ppm): rural Puno 4.9 ± 4.3. Higher indoor PM2.5 was associated with having a higher systolic BP (1.51 mmHg per interquartile range (IQR) increase, 95% CI 0.16 to 2.86), a higher diastolic BP (1.39 mmHg higher DBP per IQR increase, 95% CI 0.52 to 2.25), and a higher eCO (2.05 ppm higher per IQR increase, 95% CI 0.52 to 3.57). When stratifying by biomass cookstove use, our results were consistent with effect measure modification in the association between PM2.5 and eCO: among biomass users eCO was 0.20 ppm higher per IQR increase in PM2.5 (95% CI − 2.05 to 2.46), and among non-biomass users eCO was 5.00 ppm higher per IQR increase in PM2.5 (95% CI 1.58 to 8.41). We did not find associations between indoor air concentrations and CRP or HbA1c outcomes.

Conclusions
Excessive indoor concentrations of PM2.5 are widespread in homes across varying levels of urbanisation, altitude, and biomass cookstove use in Peru and are associated with worse BP and higher eCO.
Alveolar lipids in pulmonary disease. A review
Authors: Agudelo Christina W. , Samaha Ghassan , Garcia-Arcos Itsaso 
Published: June 2020

AbstractLung lipid metabolism participates both in infant and adult pulmonary disease. The lung is composed by multiple cell types with specialized functions and coordinately acting to meet specific physiologic requirements. The alveoli are the niche of the most active lipid metabolic cell in the lung, the type 2 cell (T2C). T2C synthesize surfactant lipids that are an absolute requirement for respiration, including dipalmitoylphosphatidylcholine. After its synthesis and secretion into the alveoli, surfactant is recycled by the T2C or degraded by the alveolar macrophages (AM). Surfactant biosynthesis and recycling is tightly regulated, and dysregulation of this pathway occurs in many pulmonary disease processes. Alveolar lipids can participate in the development of pulmonary disease from their extracellular location in the lumen of the alveoli, and from their intracellular location in T2C or AM. External insults like smoke and pollution can disturb surfactant homeostasis and result in either surfactant insufficiency or accumulation. But disruption of surfactant homeostasis is also observed in many chronic adult diseases, including chronic obstructive pulmonary disease (COPD), and others. Sustained damage to the T2C is one of the postulated causes of idiopathic pulmonary fibrosis (IPF), and surfactant homeostasis is disrupted during fibrotic conditions. Similarly, surfactant homeostasis is impacted during acute respiratory distress syndrome (ARDS) and infections. Bioactive lipids like eicosanoids and sphingolipids also participate in chronic lung disease and in respiratory infections. We review the most recent knowledge on alveolar lipids and their essential metabolic and signaling functions during homeostasis and during some of the most commonly observed pulmonary diseases.

AbstractBackgroundIn metabolic disorders, myocardial fatty infiltration is critically associated with lipotoxic cardiomyopathy.MethodsTwentyPsammomys obesusgerbils were randomly assigned to normal plant or high fat diet. Sixteen weeks later, myocardium was sampled for pathobiological evaluation.ResultsA sixteen-week high fat diet resulted in myocardial structure disorganization, with collagen deposits, lipid accumulation, cardiomyocyte apoptosis and inflammatory cell infiltration. Myocardial expressions of glucose transporter GLUT1 and pyruvate dehydrogenase (PDH) inhibitor, PDH kinase (PDK)4 increased, while insulin-regulated GLUT4 expression remained unchanged. Myocardial expressions of molecules regulating fatty acid transport, CD36 and fatty acid binding protein (FABP)3, were increased, while expression of rate-controlling fatty acid β-oxidation, carnitine palmitoyl transferase (CPT)1B decreased. Myocardial expression of AMP-activated protein kinase (AMPK), decreased, while expression of peroxisome proliferator activated receptors (PPAR)-α and -γ did not change.ConclusionIn high fat diet fedPsammomys obesus, an original experimental model of nutritionally induced metabolic syndrome mixing genetic predisposition and environment interactions, a short period of high fat feeding was sufficient to induce myocardial structural alterations, associated with altered myocardial metabolic gene expression in favor of lipid accumulation.

Abstract
Background
Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disease with unknown pathogenesis. However, the treatment of Diane-35 combined with metformin can improve the endocrine and ovulation of PCOS. In this study, we investigated the effects of Diane-35 combined with metformin (DM) treatment on ovulation and glucose metabolism in a PCOS rat model.

Methods
Sprague Dawley rats were divided into 3 groups, control group, model group (PCOS group) and Diane-35 combined with metformin (PCOS + DM group). The mRNA expression levels were determined by qRT-PCR. The hormone levels were determined by enzyme-linked immunosorbent assay. Immunostaining detected the protein levels of lactate dehydrogenase A (LDH-A), pyruvate kinase isozyme M2 (PKM2) and sirtuin 1 (SIRT1) in the ovarian tissues. TNUEL assay was performed to determine cell apoptosis in the PCOS rats. The metabolites in the ovarian tissues were analyzed by liquid chromatography with tandem mass spectrometry.

Results
PCOS rats showed an increased in body weight, levels of luteinizing hormone and testosterone and insulin resistance, which was significantly attenuated by the DM treatment. The DM treatment improved disrupted estrous cycle and increased the granulosa cells of the ovary in the PCOS rats. The decreased proliferation and increased cell apoptosis of granulosa cells in the ovarian tissues of PCOS rats were significantly reversed by the DM treatment. The analysis of metabolics revealed that ATP and lactate levels were significantly decreased in PCOS rats, which was recovered by the DM treatment. Furthermore, the expression of LDH-A, PKM2 and SIRT1 was significantly down-regulated in ovarian tissues of the PCOS rats; while the DM treatment significantly increased the expression of LDH-A, PKM2 and SIRT1 in the ovarian tissues of the PCOS rats.

Conclusion
In conclusion, our study demonstrated that Diane-35 plus metformin treatment improved the pathological changes in the PCOS rats. Further studies suggest that Diane-35 plus metformin can improve the energy metabolism of the ovary via regulating the glycolysis pathway. The mechanistic studies indicated that the therapeutic effects of Diane-35 plus metformin treatment in the PCOS rats may be associated with the regulation of glycolysis-related mediators including PKM2, LDH-A and SIRT1.
Policy context, coherence and disjuncture in the implementation of the Ideal Clinic Realisation and Maintenance programme in the Gauteng and Mpumalanga provinces of South Africa

AbstractBackgroundUniversal health coverage is a key target of the Sustainable Development Goals and quality of care is fundamental to its attainment. In South Africa, the National Health Insurance (NHI) system is a major health financing reform towards universal health coverage. The Ideal Clinic Realisation and Maintenance (ICRM) programme aims to improve the quality of care at primary healthcare level in preparation for NHI system implementation. This study draws on Bressers’ Contextual Interaction Theory to explore the wider, structural and specific policy context of the ICRM programme and the influence of this context on policy actors’ motivation, cognition and perceived power.MethodsThis was a nested qualitative study, conducted in two NHI pilot districts in the Gauteng and Mpumalanga Provinces of South Africa. Following informed consent, we conducted in-depth interviews with key informants involved in the conceptualisation and implementation of the ICRM programme. The questions focused on ICRM policy context, rationale and philosophy, intergovernmental relationships, perceptions of roles and responsibilities in implementation, ICRM programme resourcing, and implementation progress, challenges and constraints. We used thematic analysis, informed by Bressers’ theory, to analyse the data.ResultsA total of 36 interviews were conducted with key informants from national, provincial and local government. The wider context of the ICRM programme implementation was the drive to improve the quality of care at primary healthcare level in preparation for NHI. However, the context was characterised by contestations about the roles and responsibilities of the three government spheres and weak intergovernmental relationships. Notwithstanding examples of strong local leadership, the disjuncture between two national quality of care initiatives and resource constraints influenced policy actors’ experiences and perceptions of the ICRM programme. They expressed frustrations about the lack of or diffuse accountability and their lack of involvement in decision-making, thus questioning the sustainability of the ICRM programme.ConclusionsNational health sector reforms should consider the context of policy implementation and potential impact on actors’ motivation, cognition and power. All relevant policy actors should be involved in policy design and implementation. A clear communication strategy and ongoing monitoring and evaluation are prerequisites for implementation success.
Adolescent health programming in India: a rapid review

Published: June 2020

Abstract
Background
Recognizing the potential of the country’s large youth population and the importance of protecting and supporting its health and well-being, the Government of India committed to strengthening its programmes and systems for adolescents, initially through the Adolescent Reproductive and Sexual Health Strategy (ARSH) launched in 2005 and, subsequently, through the National Adolescent Health Programme (Rashtriya Kishore Swaasthya Karyakram or RKSK) launched in 2014. In 2016, in response to a request from the Government of India, the World Health Organisation undertook a rapid programme review of ARSH and RKSK at the national level and in four states (Haryana, Madhya Pradesh, Maharashtra and Uttarakhand) to identify and document lessons learnt in relation to four domains of the programmes (governance, implementation, monitoring and linkages) that could be used to enhance current and future adolescent health programming in India.

Methodology and findings
A rapid programme review methodology was utilised to gain an overview of the successes and challenges of the two adolescent health programmes. A desk review of policy statements, Program Implementation Plans (PIPs) (Program Implementation Plan (PIP) is an annual process of planning, approval and allocation of budgets of various programmes under the National Health Mission (NHM). It is also used for monitoring of physical and financial progress made against the approved activities and budget.
), reports and data provided by the four State governments was conducted alongside 70 semi-structured interviews with health, education and NGO officials at national, state, district and block levels. Data showed that the ARSH Strategy put adolescent health on the agenda for the first time in India, though insufficient human and financial resources were mobilised to ensure maximum impact. Further, the Strategy’s focus on clinical service provision in a limited number of health facilities with a complementary focus on promoting community support and adolescent demand for them meant that services were not as easily accessible to adolescents in their communities, and in addition many were not even aware of them. Under RKSK, significant investment has been made in adequate management structures, as well as in community engagement and clinical service delivery at all levels of the health system. Monitoring the quality of service delivery remains a challenge in all four of the states, as does training of counsellors, nodal officers and other implementing partners. Additionally, further thought and action are required to ensure that peer educators are properly trained, supported and retained for the programme.

Conclusions
India’s RKSK clearly integrated learning from the earlier ARSH Strategy. The findings of this review present an opportunity for the government and its partners to ensure that future investment in adolescent health programming continues to be framed around lessons learnt across India.
The process of risky sexual behaviors formation in women drug users: a protocol for a grounded theory study

Published: June 2020

Abstract
Background
Drug use is an important underlying factor in risky sexual behaviors. Risky sexual behaviors can lead to STIs and HIV/AIDS, especially in women. For better understanding of the relationship between drug use and risky sexual behaviors in women, it is necessary to identify the process of the formation of these behaviors that is a multidimensional process influenced by multiple socio-cultural factors. Therefore, the present study aims to explore the process of risky sexual behaviors formation in women drug users.

Methods
This is a grounded theory qualitative study with Corbin and Strauss approach. The participants of the study are women drug users with risky sexual behaviors who, using purposeful sampling method, will be selected from the Counseling and Harm Reduction centers for vulnerable women, the Drug Rehabilitation centers affiliated to the Isfahan University of Medical Sciences, Therapeutic Community Rehabilitation centers, Drop in Centers affiliated to the Welfare Organization, Medium-term Residential centers (women’s camps), and Women’s Empowerment centers in Isfahan, Iran. Sampling will continue using snowball method and the strategy of maximum variation in terms of the age, occupation, education, duration of the drug use, and type of the drug. During the sampling process, theoretical sampling will gradually replace purposeful sampling, so that sampling will proceed based on the emergence of the theory and for understanding of the concept and, then, the next participants will be selected. Sampling will continue until data saturation is reached. Data will be collected using individual semi-structured in-depth interviews, observation, field notes, and memo writing. Data will be coded as they are collected, and the analysis will be performed at three levels of open, axial, and selective coding and based on the constant comparative analysis. The four criteria of credibility, dependability, transferability and confirmability will be used to ensure the trustworthiness of the data.

Discussion
The findings of the present study are expected to provide a better understanding of the process of risky sexual behaviors formation in women drug users. The findings may also lead to the identification of the barriers and factors contributing to the formation of such behaviors and, finally, will promote the reproductive and sexual health of these women. This study can also provide the guide and the ground for designing and conducting further studies in the related areas through using various qualitative and quantitative methods.
Providers’ perceptions of communication and women’s autonomy during childbirth: a mixed methods study in Kenya
Authors: Afulani Patience A. , Buback Laura , Kelly Ann Marie , Kirumbi Leah , Cohen Craig R. , Lyndon Audrey 
Published: June 2020

Abstract
Background
Effective communication and respect for women’s autonomy are critical components of person-centered care. Yet, there is limited evidence in low-resource settings on providers’ perceptions of the importance and extent of communication and women’s autonomy during childbirth. Similarly, few studies have assessed the potential barriers to effective communication and maintenance of women’s autonomy during childbirth. We sought to bridge these gaps.

Methods
Data are from a mixed-methods study in Migori County in Western Kenya with 49 maternity providers (32 clinical and 17 non-clinical). Providers were asked structured questions on various aspects of communication and autonomy followed by open ended questions on why certain practices were performed or not. We conducted descriptive analysis of the quantitative data and thematic analysis of the qualitative data.

Results
Despite acknowledging the importance of various aspects of communication and women’s autonomy, providers reported incidences of poor communication and lack of respect for women’s autonomy: 57% of respondents reported that providers never introduce themselves to women and 38% reported that women are never able to be in the birthing position of their choice. Also, 33% of providers reported that they did not always explain why they are doing exams or procedures and 73% reported that women were not always asked for permission before exams or procedures. The reasons for lack of communication and autonomy fall under three themes with several sub-themes: (1) work environment—perceived lack of time, language barriers, stress and burnout, and facility culture; (2) provider knowledge, intentions, and assumptions—inadequate provider knowledge and skill, forgetfulness and unconscious behaviors, self-protection and comfort, and assumptions about women’s knowledge and expectations; and (3) women’s ability to demand or command effective communication and respect for their autonomy—women’s lack of participation, women’s empowerment and provider bias.

Conclusions
Most providers recognize the importance of various aspects of communication and women’s autonomy, but they fail to provide it for various reasons. To improve communication and autonomy, we need to address the different factors that negatively affect providers’ interactions with women.
Augmenting propulsion demands during split-belt walking increases locomotor adaptation of asymmetric step lengths
Authors: Sombric Carly J. , Torres-Oviedo Gelsy 
Published: June 2020

Abstract
Background
Promising studies have shown that the gait symmetry of individuals with hemiparesis due to brain lesions, such as stroke, can improve through motor adaptation protocols forcing patients to use their affected limb more. However, little is known about how to facilitate this process. Here we asked if increasing propulsion demands during split-belt walking (i.e., legs moving at different speeds) leads to more motor adaptation and more symmetric gait in survivors of a stroke, as we previously observed in subjects without neurological disorders.

Methods
We investigated the effect of propulsion forces on locomotor adaptation during and after split-belt walking in the asymmetric motor system post-stroke. To test this, 12 subjects in the chronic phase post-stroke experienced a split-belt protocol in a flat and incline session so as to contrast the effects of two different propulsion demands. Step length asymmetry and propulsion forces were used to compare the motor behavior between the two sessions because these are clinically relevant measures that are altered by split-belt walking.

Results
The incline session resulted in more symmetric step lengths during late split-belt walking and larger after-effects following split-belt walking. In both testing sessions, subjects who have had a stroke adapted to regain speed and slope-specific leg orientations similarly to young, intact adults. Importantly, leg orientations, which were set by kinetic demands, during baseline walking were predictive of those achieved during split-belt walking, which in turn predicted each individual’s post-adaptation behavior. These results are relevant because they provide evidence that survivors of a stroke can generate the leg-specific forces to walk more symmetrically, but also because we provide insight into factors underlying the therapeutic effect of split-belt walking.

Conclusions
Individuals post-stroke at a chronic stage can adapt more during split-belt walking and have greater after-effects when propulsion demands are augmented by inclining the treadmill surface. Our results are promising since they suggest that increasing propulsion demands during paradigms that force patients to use their paretic side more could correct gait asymmetries post-stroke more effectively.
