RESUMO

This paper examines the effect of green foreign direct investment (GFDI) on environmental quality (EQ) in 34 less-developed countries (LDCs) from 2003 to 2021. We analyze balanced panel data using Feasible Generalized Least Squares (FGLS) and Panel-Corrected Standard Errors (PCSE). Our findings reveal several vital insights: (1) GFDI helps improve EQ. (2) Environmental costs associated with economic growth are negative. (3) Trade openness positively influences EQ. (4) EQ is enhanced by institutional quality, energy use, and population expansion in the chosen countries. (5) The existence of a U-shaped curve was established. This is valuable to the relatively scanty literature on GFDI, especially in LDCs. To the best of our awareness, this study simultaneously employs the Load Capacity Factor (LCF) and Total Value of Announced Greenfield projects as proxies for environmental sustainability and GFDI for the first time. Secondly, incorporating PCSE and FGLS models in this context is an innovative methodological strategy. The present research work provides to the existing theoretical and empirical discussions on GFDI and EQ and has practical implications that inform policy-making.

RESUMO

Promotion appears to be the least effective but is nevertheless often the only available, means to achieve increased access to sanitation services, especially at scale, in lower-income countries. A cursory examination of the history of past and present approaches to sanitation promotion, including sanitation marketing, community development, community-led total sanitation and public health, shows that they have a variety of features and characteristics which make them distinctive. Unfortunately, rigorous evaluation has not kept pace with this proliferation of approaches, so it is difficult to recommend any one approach over the others, based on empirical performance in a range of circumstances. However, I argue that a 'hybrid' approach which exhibits a number of salient features from all of the previous approaches is likely to be a good bet. I present a recent example of such a hybrid programme which proved to significantly increase the rate of improved sanitation coverage through promotion (without subsidy of any kind) at scale in Tanzania. I suggest other sanitation promotion programs may want to think about adopting similar practices in their own programming going forward.

RESUMO

Drones (uncrewed aerial vehicles or UAVs) introduce new opportunities to improve vaccine distribution systems, particularly in regions with limited transportation infrastructure where maintaining the cold chain is challenging. This paper addresses the use of drones to deliver vaccines to hard-to-reach populations using a novel optimization model to strategically design a multimodal vaccine distribution network. The model is illustrated in a case study for distributing routine childhood vaccines in Vanuatu, a South Pacific island nation with limited transportation infrastructure. Our research incorporates multiple drone types, recharging of drones, a cold chain travel time limit, transshipment delays for switching transport modes, and practical limits on the vaccine paths and drone trips. The goal is to locate facilities (distribution centers, drone bases, and relay stations) and design vaccine paths to minimize transportation costs, including the fixed costs for facilities and transportation links and variable costs for transportation through the network. Results show large potential cost savings and improved service quality provided by incorporating drones in a multimodal vaccine distribution system. Results also show the impact of introducing drones on the usage of other more expensive or slower transport modes.

RESUMO

Utilizing technology acceptance model (TAM), this paper investigated perceptions of academics at Yemeni universities toward the intention to adopt and integrate technology into accounting education. This model has yet to be widely validated in less developed countries (LDCs) such as Yemen. Thus, there is a need to promote its cross-cultural validity. An extension of the TAM has been employed by considering not only perceived usefulness and ease of usage but also social influence and self-efficiency. The hypotheses were tested using SmartPLS on a sample of 138 academics. The results show that the proposed expanded TAM model could predict the acceptance of technology in the context of accounting education in Yemen, a less developed nation. This paper exhibits that the proposed expanded TAM interpreted 59.4% of the variance in the behavioral intention of IT usage. Furthermore, the model paths demonstrated that perceived usefulness, ease of usage, attitude, and self-efficiency were all significant in determining behavioral intention. However, social influence had not shown any significant impact on behavioral intention. Academics' perceptions of technology adoption and integration into education are essential in implementing technology-related innovations. Therefore, this paper would be helpful in education policymaking on technology adoption and integration in accounting education in Yemen and other similar countries.

RESUMO

Background: To develop effective antimicrobial stewardship programs (ASPs) for low- and middle-income countries (LMICs), it is important to identify key targets for improving antimicrobial use. We sought to systematically describe the prevalence and patterns of antimicrobial use in three LMIC hospitals. Methods: Consecutive patients admitted to the adult medical wards in three tertiary care hospitals in Tanzania, Kenya, and Sri Lanka were enrolled in 2018-2019. The medical record was reviewed for clinical information including type and duration of antimicrobials prescribed, indications for antimicrobial use, and microbiologic testing ordered. Results: A total of 3,149 patients were enrolled during the study period: 1,103 from Tanzania, 750 from Kenya, and 1,296 from Sri Lanka. The majority of patients were male (1,783, 56.6% overall) with a median age of 55 years (IQR 38-68). Of enrolled patients, 1,573 (50.0%) received antimicrobials during their hospital stay: 35.4% in Tanzania, 56.5% in Kenya, and 58.6% in Sri Lanka. At each site, the most common indication for antimicrobial use was lower respiratory tract infection (LRTI; 40.2%). However, 61.0% received antimicrobials for LRTI in the absence of LRTI signs on chest radiography. Among patients receiving antimicrobials, tools to guide antimicrobial use were under-utilized: microbiologic cultures in 12.0% and microbiology consultation in 6.5%. Conclusion: Antimicrobials were used in a substantial proportion of patients at tertiary care hospitals across three LMIC sites. Future ASP efforts should include improving LRTI diagnosis and treatment, developing antibiograms to direct empiric antimicrobial use, and increasing use of microbiologic tests.

RESUMO

The worldwide epidemic of diabetes mellitus and hyperglycemia in pregnancy (HIP) presents many challenges, some of which are country-specific. To address these specific problems, parochial resolutions are essential. In India, the government, by working in tandem with (a) national groups such as the Diabetes in Pregnancy Study Group of India, and (b) global organizations such as the International Diabetes Federation, has empowered the medical and paramedical staff throughout the country to manage HIP. Additionally, despite their academic university backgrounds, Indian health planners have provided practical guidelines for caregivers at the ground level, who look up to these experts for guidance. This multipronged process has helped to negotiate some of the multiple problems that are indigenous and exclusive to India. This review traces the Indian journey to manage and prevent HIP with simple, constructive, and pragmatic solutions.

RESUMO

Abstract Background: Neonatal jaundice is a frequent benign condition in newborns. However, a rapid diagnosis must be established for its most appropriate treatment. The objective of this study was to measure the correlation between total serum bilirubin (TSB) and transcutaneous bilirubin (in forehead and sternum) in full-term newborns at 3400 m above sea level. Methods: We conducted a prospective and cross-sectional study in full-term newborns with clinical jaundice from the Hospital Regional in Cusco-Peru. General characteristics and measurement of TSB, transcutaneous forehead bilirubin (TcBF), and transcutaneous bilirubin in the sternum (TcBS) were explored. Correlation, sensitivity, and specificity were calculated. Receiver operating characteristic (ROC) curves were constructed using the SPSS statistical package, version 22.0. Results: A total of 123 newborns were evaluated. The mean bilirubin values were 13.7 ± 3.5 for TcBF, 14.1 ± 3.1 for TcBS, and 13.8 ± 3.9 for TSB. In addition, Pearson correlation coefficients between TSB/TcBF and TSB/TcBS were 0.90 and 0.91, respectively (p < 0.001). For the percentile 95 cut-off point, a sensitivity of 93% and 100% and a specificity of 89% and 80% were obtained for TcBF and TcBS, respectively, with an area under the curve of 0.813 for TcBF and 0.815 for TcBS (p < 0.001) Conclusions: Measurement of transcutaneous bilirubin is a fast and painless method that can be considered a reliable tool for screening and monitoring neonatal jaundice, but not for a definitive diagnosis to decide the use of phototherapy in full-term newborns at 3400 m above sea level.


Resumen Introducción: La ictericia neonatal es una condición benigna y frecuente en los recién nacidos, en quienes es preciso hacer un diagnóstico rápido para el tratamiento más adecuado. El objetivo de este estudio fue determinar la correlación entre la bilirrubina sérica total (BST) y la bilirrubina transcutánea (frente y esternón) en recién nacidos a término a 3400 metros sobre el nivel del mar. Método: Estudio prospectivo y transversal en recién nacidos con ictericia clínica en el Hospital Regional de la Ciudad de Cusco, Perú. Se exploraron las características generales y se midieron la BST, la bilirrubina transcutánea en la frente (BTcF) y la bilirrubina transcutánea en el esternón (BTcE). Se calcularon la correlación, la sensibilidad y la especificidad, y se elaboraron las curvas de características operativas del receptor (ROC) con el paquete estadístico SPSS 22.0. Resultados: Se evaluaron 123 recién nacidos. El promedio de la BST fue de 13.8 ± 3.9, el de la BTcF fue de 13.7 ± 3.5 y el de la BTcE fue de 14.1 ± 3.1. La correlación entre BST/BTcF y BST/BTcE fue de 0.90 y 0.91, respectivamente (p < 0.001). Para el punto de corte del percentil 95 según el nomograma Bhutani se obtuvo una sensibilidad del 93% y el 100%, y una especificidad del 89% y el 80%, para la BTcF y la BTcE, respectivamente, con un área bajo la curva ROC de 0.813 para la BTcF y de 0.815 para la BTcE (p < 0.001). Conclusiones: La medición de la bilirrubina transcutánea es un método rápido e indoloro, y podría ser considerado confiable para el despistaje y el seguimiento de la ictericia neonatal, mas no para un diagnóstico definitivo con el fin de decidir el uso de fototerapia en recién nacidos a término a 3400 metros sobre el nivel del mar.

RESUMO

Background: Proper hand hygiene (HH) practices have been shown to reduce healthcare-acquired infections. Several potential challenges in low-income countries might limit the feasibility of effective HH, including preexisting knowledge gaps and staffing. Aim: We sought to evaluate the feasibility of the implementation of effective HH practice at a teaching hospital in Rwanda. Methods: We conducted a prospective quality improvement project in the intensive care unit (ICU) at the Kigali University Teaching Hospital. We collected data before and after an intervention focused on HH adherence as defined by the World Health Organization '5 Moments for Hand Hygiene' and assuring availability of HH supplies. Pre-intervention data were collected throughout July 2019, and HH measures were implemented in August 2019. Post-implementation data were collected following a 3-month wash-in. Results: In total, 902 HH observations were performed to assess pre-intervention adherence and 903 observations post-intervention adherence. Overall, HH adherence increased from 25% (222 of 902 moments) before intervention to 75% (677 of 903 moments) after intervention (P < 0.001). Improvement was seen among all health professionals (nurses: 19-74%, residents: 23-74%, consultants: 29-76%). Conclusions: Effective HH measures are feasible in an ICU in a low-income country. Ensuring availability of supplies and training appears key to effective HH practices.

RESUMO

AIM: In India, the need for rural palliative care is increasing with the rising number of people diagnosed with late-stage cancers. Rural areas also have a shortage of trained medical personnel to deliver palliative care. To address these needs, a home-based palliative care program using community health workers (CHWs) to facilitate care delivery was developed to extend the reach of a cancer center's palliative care services outside of Kolkata, India. The research question guiding this qualitative study was, how feasible, useful, and acceptable was this program from the perspectives of the clinical team and CHWs who delivered the intervention? METHODS: This qualitative descriptive study used a grounded theory approach and the iterative constant comparative method to collect and analyze data from the key stakeholder interviews. Ten qualitative interviews took place at the Saroj Gupta Cancer Center and Research Institute and were conducted with the CHWs who delivered the home-based palliative care intervention (n = 3) and the clinical team who provided them with training, support, and supervision (n = 7). RESULTS: Three major themes emerged (a) CHWs' desire and need for more training, (b) the need for tailoring of existing intervention protocols and modifying expectations of stakeholders, and (c) the need for considerations for ensuring program sustainability. CONCLUSIONS: The study provided evidence that the utilization of CHWs to facilitate delivery of palliative care is a feasible model worthy of consideration and further research testing in low-resource settings.

RESUMO

Research on early-life mortality in contemporary and historical populations has shown that infant and child mortality tend to cluster in a limited number of high-mortality families, a phenomenon known as 'mortality clustering'. This paper is the first to review the literature on the role of the family in early-life mortality. Contemporary results, methodological and theoretical shortfalls, recent developments, and opportunities for future research are all discussed in this review. Four methodological approaches are distinguished: those based on sibling deaths, mother heterogeneity, thresholds, and excess deaths in populations. It has become clear from research to date that the death of an older child harms the survival chances of younger children in that family, and that fertility behaviour, earlier stillbirths, remarriages, and socio-economic status all explain mortality clustering to some extent.

RESUMO

The use of traditional, complementary, and alternative medicine (TCAM) for cancer may influence the delivery or effectiveness of conventional cancer treatment. In this systematic review, we aimed to (1) summarise the available prevalence data on traditional medicine use by cancer patients in less developed countries (LDCs), and (2) stratify the prevalence data by world region and country income level. A literature search for cancer, TCAM, and low income (LI) and lower-middle income (LMI) countries was conducted across 5 databases. A total of 2,365 publications were reviewed for eligibility, of which 25 studies met inclusion criteria. The combined sample size was 6,878 cancer patients, with a median of 54.5% reporting the use of TCAM for cancer care. Of the studies providing data on the concomitant use of TCAM and conventional cancer treatment (n = 4,872 cancer patients), a median of 26.7% of participants reported combining the two systems of medicine. From the data available, it is apparent that TCAM use among cancer patients in less developed countries is common; however, additional studies are needed to support the safe and effective management of cancer for patients in LI and LMI countries.

RESUMO

OBJECTIVES: Court documents have proven that a manufacturer-orchestrated strategy tried to promote gabapentin by distorting evidence in randomized trials. Given this background, we aimed to assess whether implausibly large treatment effects for gabapentin and for a similar gabapentinoid, pregabalin may have been published. STUDY DESIGN AND SETTING: We identified meta-analyses on gabapentin or pregabalin on any outcome from Google Scholar, PubMed, and EMBASE. We explored excess of significance in meta-analyses and whether outlier studies with extreme results (differing >0.8 standard deviations from the summary effect of the meta-analysis) were scrutinized. RESULTS: All 10 evaluated meta-analyses showed statistically significant favorable findings. Heterogeneity I2 estimates exceeding 90% were noted in four meta-analyses of postoperative pain. In these four meta-analyses, 77 studies had estimates differing >0.8 standard deviations from the summary estimate. Thirty-nine of 77 represented extremely favorable results, and 33 of them came from less developed countries with no tradition of clinical research, 22 reported no information on funding, and 20 reported no conflicts of interest. Conversely, 27 of 38 studies with unfavorable results came from more developed countries. CONCLUSION: Extremely favorable outlier studies in the meta-analyzed literature of gabapentin and pregabalin may be a footprint of bias in studies done in less developed countries.

RESUMO

This study examines the prevalence of suspected cervical cancer (established through the use of visual inspection with Lugol's Iodine - VILI) among outpatients attending Surat Municipal Institute of Medical Education & Research Hospital, India. A cross-sectional study was conducted on 356 patients; 178 with an established sexually transmitted disease (STD) and 178 patients without. Patients with positive results were investigated with cervical biopsy; out of 356 patients, 21.91% patients with STD and 12.35% patients without STD tested positive for VILI respectively (p = .017). The factors found to be significantly associated with a positive VILI test were STD, marital status, oral contraceptive pill use, a complaint of PV bleeding, white discharge on speculum examination (PS) and cervical erosion on PS. On applying multiple logistic regression, STD, age of patient in years, parity, OC pill use, a complaint of PV bleeding and cervical erosion on PS were found to be significant predictors of VILI positivity among the patients. STD patients are 2.5 times more likely to test positive for VILI than patients without STD. In Indian populations comparable to ours, opportunistic screening should be considered in gynaecology outpatient clinics for women presenting with complaints related to STDs.

RESUMO

In many less developed countries, household surveys collect full and summary birth histories to provide estimates of child mortality. However, full birth histories are expensive to collect and cannot provide precise estimates for small areas, and summary birth histories only provide past child mortality trends. A simple method that provides estimates for the most recent past uses questions about the survival of recent births in censuses or large household surveys. This study examines such data collected by 45 censuses and shows that on average they tend to underestimate under-5 mortality in comparison with alternative estimates, albeit with wide variations. In addition, the high non-sampling uncertainty in this approach precludes its use in providing robust estimates of child mortality at the country level. Given these findings, we suggest that questions about the survival of recent births to collect data on child mortality not be included in census questionnaires.

RESUMO

One of the aims of the WHO Global Action Plan for Influenza Vaccines (GAP) was to transfer influenza vaccine production technology to interested manufacturers and governments in developing countries, to enable greater influenza vaccine manufacturing capacity against any pandemic threat or pandemic. For this objective, the GAP was supported by an independent Technical Advisory Group (TAG) to assist WHO to select vaccine manufacturing proposals for funding and to provide programmatic support for successful grantees. While there were many challenges, for both the TAG and grantees, there were also notable successes with an additional capacity of 338-600 million pandemic vaccine doses being made possible by the programme between 2007 and 2015, and a potential capacity of more than 600 million by 2016/17 with up to one billion doses expected by 2018/19. Seasonal vaccine production was also developed in 4 countries with another 4-5 countries expected to be producing seasonal vaccine by 2018/19. The relatively small WHO investments - in time and funding - made in these companies to develop their own influenza vaccine production facilities have had quite dramatic results.

RESUMO

OBJECTIVES: We set up to evaluate the relative risk of harms in trials performed in less developed vs. more developed countries. STUDY DESIGN AND SETTING: Meta-epidemiologic evaluation using the Cochrane Database of Systematic Reviews. We considered meta-analyses with at least one randomized clinical trial (RCT) in a less developed country and one RCT in a more developed country. We targeted severe adverse events (AEs), discontinuations due to AEs, any AE, organ system-specific AEs, individual AEs, and all discontinuations due to any reason. We estimated the relative odds ratio (ROR) of harms between more and less developed countries for each topic and the summary ROR (sROR) across topics under each category of harms. RESULTS: We identified 42 systematic reviews (128 meta-analyses, 521 independent RCTs). Summary sRORs did not differ significantly from 1.00 for any harm category. Nominally significant RORs were found in only 6/128 meta-analyses. However, in 27% (35/128) of meta-analyses the ROR point estimates indicated relative differences between country settings >2-fold. Considering also ROR 95% confidence intervals, in 92% (118/128) of meta-analyses one could not exclude a 2-fold difference in both directions. CONCLUSIONS: We identified limited comparative evidence on harms in trials from these two country settings. Substantial differences in the risk point estimates were common; the potential for modest differences could rarely be excluded with confidence.

RESUMO

We offer the first empirical test of the 'stranger-interviewer norm', according to which interviewers in social, demographic, and health surveys should be strangers-not personally familiar with respondents. We use data from an experimental survey in the Dominican Republic that featured three types of interviewer: from out of town (outsiders); local but unknown to the respondent (local-strangers); and local with a previous relationship to the respondent (insiders). We were able to validate answers to up to 18 questions per respondent, mainly by checking official documents in their possession. Contrary to expectations derived from the stranger-interviewer norm, respondents were more reluctant to show the documents needed for validation when the interviewer was an outsider. Furthermore, and again at odds with the stranger-interviewer norm, we found no difference in accuracy by type of interviewer. Our results have important implications for the selection of survey interviewers in less developed and non-Western settings.
