Biomass burning in indoor environments has been highlighted as a major cause of respiratory morbidity for women and children in low-income countries. Inexpensive technological innovations which reduce such exposures are needed. This study evaluated the impact of low tech compost digesters, which generate biogas for cooking, versus traditional fuel sources on the respiratory health of nonsmoking Kenyan farmwomen. Women from 31 farms with biogas digesters were compared to age-matched women from 31 biomass-reliant farms, in June 2010. Only 43% of the biogas group reported any breathing problems, compared to 71% in the referent group (P=0.03). Referent women self-reported higher rates of shortness of breath (52% versus 30%), difficulty breathing (42% versus 23%), and chest pain while breathing (35% versus 17%) during the last 6 months (P=0.09to 0.12) compared to biogas women. Biogas women demonstrated slightly better spirometry results but differences were not statistically significant, likely due to limited latency between biogas digester installation and spirometry testing. Most biogas women reported improved personal respiratory health (87%) and improved children’s health (72%) since biogas digester installation. These findings suggest that using biogas in cookhouses improves respiratory symptoms but long-term impacts on lung function are unclear.

Abstract Background Healthcare associated infections (HAI) are estimated to affect up to 15% of hospital inpatients in low-income countries (LICs). A critical but often neglected aspect of HAI prevention is basic environmental hygiene, particularly surface cleaning and linen management. TEACH CLEAN is an educational intervention aimed at improving environmental hygiene. We evaluated the effectiveness of this intervention in a pilot study in three high-volume maternity and newborn units in Dar es Salaam, Tanzania. Methods This study design prospectively evaluated the intervention as a whole, and offered a before-and-after comparison of the impact of the main training. We measured changes in microbiological cleanliness [Aerobic Colony Counts (ACC) and presence of Staphylococcus aureus] using dipslides, and physical cleaning action using gel dots. These were analysed with descriptive statistics and logistic regression models. We used qualitative (focus group discussions, in-depth interviews, and semi-structured observation) and quantitative (observation checklist) tools to measure why and how the intervention worked. We describe these findings across the themes of adaptation, fidelity, dose, reach and context. Results Microbiological cleanliness improved during the study period (ACC pre-training: 19%; post-training: 41%). The odds of cleanliness increased on average by 1.33 weekly during the pre-training period (CI = 1.11–1.60), and by 1.08 (CI = 1.03–1.13) during the post-training period. Cleaning action improved only in the pre-training period. Detection of S. aureus on hospital surfaces did not change substantially. The intervention was well received and considered feasible in this context. The major pitfalls in the implementation were the limited number of training sessions at the hospital level and the lack of supportive supervision. A systems barrier to implementation was lack of regular cleaning supplies. Conclusions The evaluation suggests that improvements in microbiological cleanliness are possible using this intervention and can be sustained. Improved microbiological cleanliness is a key step on the pathway to infection prevention in hospitals. Future research should assess whether this bundle is cost-effective in reducing bacterial and viral transmission and infection using a rigorous study design.

AbstractThe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the COVID-19 global pandemic has infected over 25 million people worldwide and resulted in the death of millions. The COVID-19 pandemic has also resulted in a shortage of personal protective equipment (PPE) in many regions around the world, particularly in middle- and low-income countries. The shortages of PPE, such as N95 respirators, is something that will persist until an effective vaccine is made available. Thus, devices that while being easy to operate can also be rapidly deployed in health centers, and long-term residences without the need for major structural overhaul are instrumental to sustainably use N95 respirators. In this report, we present the design and validation of a decontamination device that combines UV-C & B irradiation with mild-temperature treatment. The device can decontaminate up to 20 masks in a cycle of < 30 min. The decontamination process did not damage or reduce the filtering capacity of the masks. Further, the efficacy of the device to eliminate microbes and viruses from the masks was also evaluated. The photothermal treatment of our device was capable of eradicating > 99.9999% of the bacteria and > 99.99% of the virus tested.

BackgroundChildren are recognised as at lower risk of severe COVID-19 compared with adults, but the impact of immunosuppression is yet to be determined. This study aims to describe the clinical course of COVID-19 in children with kidney disease taking immunosuppressive medication and to assess disease severity.MethodsCross-sectional study hosted by the European Rare Kidney Disease Reference Network and supported by the European, Asian and International paediatric nephrology societies. Anonymised data were submitted online for any child (age <20 years) with COVID-19 taking immunosuppressive medication for a kidney condition. Study recruited for 16 weeks from 15 March 2020 to 05 July 2020. The primary outcome was severity of COVID-19.Results113 children were reported in this study from 30 different countries. Median age: 13 years (49% male). Main underlying reasons for immunosuppressive therapy: kidney transplant (47%), nephrotic syndrome (27%), systemic lupus erythematosus (10%). Immunosuppressive medications used include: glucocorticoids (76%), mycophenolate mofetil (MMF) (54%), tacrolimus/ciclosporine A (58%), rituximab/ofatumumab (11%). 78% required no respiratory support during COVID-19 illness, 5% required bi-level positive airway pressure or ventilation. Four children died; all deaths reported were from low-income countries with associated comorbidities. There was no significant difference in severity of COVID-19 based on gender, dialysis status, underlying kidney condition, and type or number of immunosuppressive medications.ConclusionsThis global study shows most children with a kidney disease taking immunosuppressive medication have mild disease with SARS-CoV-2 infection. We therefore suggest that children on immunosuppressive therapy should not be more strictly isolated than children who are not on immunosuppressive therapy.

Purpose This paper aims to investigate the long-run impact of selected foreign capital inflows, including aid, remittances, foreign direct investment (FDI), trade and debt, on the economic growth of 21 low-income countries in the Sub Saharan Africa (SSA) region, during the period 1990–2018. Design/methodology/approach To obtain this objective and for robust analysis, a parametric approach, which was dynamic ordinary least squares, and a non-parametric technique, which was fully modified ordinary least squares, were used. Findings The results of both models confirmed that, in the long run, trade and aid affected the growth rate of the per capita income in these countries in a positive way. However, external debt seemed to have an adverse influence on such growth. Originality/value First, this is the initial study that has addressed this matter across a homogenous group of countries in the SSA region. Second, while most of the previous studies regarding capital inflows into the SSA region have focused on the impact of only one or two aspects of such foreign capital inflows on growth, the present study, instead, examined the impact of five types of foreign capital inflows (aid, remittances, FDI, trade and debt).

AbstractAvian influenza outbreaks have been occurring on smallholder poultry farms in Asia for two decades. Farmer responses to these outbreaks can slow down or accelerate virus transmission. We used a longitudinal survey of 53 small-scale chicken farms in southern Vietnam to investigate the impact of outbreaks with disease-induced mortality on harvest rate, vaccination, and disinfection behaviors. We found that in small broiler flocks (≤16 birds/flock) the estimated probability of harvest was 56% higher when an outbreak occurred, and 214% higher if an outbreak with sudden deaths occurred in the same month. Vaccination and disinfection were strongly positively correlated with flock size and farm size, respectively. Small-scale farmers – the overwhelming majority of poultry producers in low-income countries – tend to rely on rapid sale of birds to mitigate losses from diseases. As depopulated birds are sent to markets or trading networks, this reactive behavior has the potential to enhance onward transmission.One sentence summaryA cohort study of fifty three small-scale poultry farms in southern Vietnam reveals that when outbreaks occur with symptoms similar to highly pathogenic avian influenza, farmers respond by sending their chickens to market early, potentially exacerbating the effects of the outbreak.

BACKGROUND The impact of mobile phones and their applications in healthcare (mobile health) is well established for a range of diseases and cross-cutting complications, such as pain. While numerous mobile health (mHealth) pain interventions have been established, an evaluation of their prevalence, adequacy and distribution remains limited. OBJECTIVE This study aims at reviewing and comparing current pain management mHealth tools in high- versus low-income countries. METHODS A literature and application (app) store search was conducted in May 2021 using combinations of the following keywords: “pain management”, “pain”, “mobile health”, “telemedicine”, and “app”. Literature searches were conducted in PubMed, Scopus, Cochrane Review Library, and Google scholar. App store searches were conducted in Google Play and Apple App Store. Data characteristics descriptive analysis was performed using R software to summarize different datasets and compute p-values (P) for testing the significance of different hypotheses with the significance level set to 0.05. RESULTS The search identified 40 publications (literature search) and 230 mHealth applications (app store search), revealing a non uniform distribution of search categories (χ2= 133.7, P < 0.004) with a ratio approximating 1:6 (OR = 5.730, 95%CI:3.745-8.909, P < 0.004). About 86.7% of these 270 applications (apps) are from high-income countries, showing a statistically significant non uniform distribution of country categories: high- and low-income (χ2= 145.2, P < 0.004) approximating the theoretical distribution of a 7:1 ratio (OR = 6.476, 95%CI:4.180-10.222, P < 0.004). Moreover, there is no significant difference in the proportion of search categories between country categories ( χ2= 0.113, P = 0.737) and the difference in pain app prevalence in high- versus low-income countries is not statistically significant. Finally, we have observed that pain-tracking apps are significantly more prevalent in developed countries in comparison to low-income countries. CONCLUSIONS As expected, pain management app prevalence is higher in high-income countries. However, more research is required to readily comprehend the effectiveness of these apps.

PurposeThis study examines the relationship between prepaid debit card use and the intention to open a bank account within twelve months. The Transtheoretical Model (TTM) of Behavior Change helped to conceptualize one's stage in the process of changing from unbanked status if desired. The Theory of Planned Behavior (TPB) provided a framework to examine factors that influence banking intention. Prepaid debit card use is considered a social norm as it is a popular alternative to banking, and these accounts have increasingly mimicked bank account features in recent years.Design/methodology/approachThree in-depth focus group interviews with low-income respondents were first conducted in 2012, which revealed a prolific use of prepaid debit cards. Most participants had previous banking history, and despite negative experiences, some requested information about banking terms and “free” banking. These themes and previous studies informed a TPB-based biprobit model, which was estimated using data of an unbanked sample from 2013, 2015 and 2017 waves of the US Survey of Unbanked and Underbanked Households.FindingsThough there was banking interest in the focus groups, no significant empirical association was found between recent prepaid debit card use and banking intention. Going deeper with another sample, we found that current cardholders were equally likely to have become recently banked or to be long-term unbanked but less likely to be long-term banked. Also, factors such as a more recent relationship with banks, use of other alternative financial services for transactions and credit, smartphone ownership, and trust increase banking intention.Research limitations/implicationsThe main limitation of the study is the cross-section quantitative data. Future research may track banking status over time, particularly as financial technology (fintech) evolves with alternatives that may influence banks and customers to adapt.Practical implicationsTo compete with “leapfrog” fintech banking alternatives, bank managers should consider utilizing customer segmentation to target “at-risk” customers and former customers with products and terms tailored to meet their banking needs. Banks can also tailor digital products to capture markets in banking desserts through mobile phones.Originality/valueThis mixed-methods study is unique in that it builds on insights from earlier in-depth interviews with real unbanked groups to examine a trend in prepaid debit card use and the impact on banking interest.

Emerging market and developing economies (EMDEs) weathered the 2009 global recession relatively well. However, the impact of the global recession varied across economies. EMDEs with stronger pre-crisis fundamentals — such as large foreign exchange reserves, sound fiscal positions, and low inflation — suffered milder growth slowdowns, in part due to their greater capacity to engage in monetary and fiscal stimulus. Low-income countries were also resilient, as foreign aid and inflows of remittances remained relatively stable. In contrast, EMDEs that were heavily dependent on short-term capital flows — such as portfolio investment and cross-border bank lending — fared less well, especially those in Europe and Central Asia. A key lesson for EMDEs is the need to strengthen macroeconomic frameworks and create policy space to prepare for future global downturns.
