    The nineties have witnessed broad economic growth and prosperity throughout the nation, with improvements in all major indicators of economic well-being. Yet, many rural and urban regions continued to experience economic distress during this period. At the same time, investments in infrastructure, human capital and poverty relief continue to be targeted to these failing areas. This work examines trends in demographic indicators, economic growth and federal funding experienced between 1990 and 2000 in the federally designated Mississippi Delta region in order to answer the following questions. What impact does federal funding have on poverty in the Mississippi Delta region overall? What factors influence poverty levels, and is that influence exhibited throughout the region uniform or variable? The methods used to answer these questions include traditional and spatial exploratory or descriptive analysis, and traditional regression analysis coupled with geographically weighted regression (GWR) modeling. Results revealed that reductions in poverty were not equally felt throughout the region. Moreover, metropolitan status also had a major impact on performance along certain indicators. Lastly, the causal factors of poverty were uneven across the entire region, with clear clusters of opposite effects evidenced in some cases. A key finding was the positive impact of human resources spending on poverty in the Delta region and in the local models generated by GWR analysis. Programs important to rural areas such as agricultural supports also had a similar positive effect on poverty in most of the models. Again, the importance of local context and local institutions that are responsible for implementing federal policies is a major explanation of these results. Local results that differ substantially from the averages represented by the global regression models strengthen the case for policies and programs that are more sensitive to local differences. Of particular concern are the disparities in local and state capacity and willingness to implement programs that were previously the primary responsibility of federal institutions. For programs that remain largely the responsibility of the federal government, the findings suggest that resources must be targeted and adapted to respond to the distinctiveness of certain local areas

    In this paper, we utilize decomposition methods to document the extent and drivers of the performance gap in Malawi between firms with a female owner and firms with a male owner. We find that, on average, male-owned businesses in Malawi earn profits more than double (120%) those of female-owned businesses. We use Kitagawa-Oaxaca-Blinder (KOB) mean-decomposition techniques and recentered influence function (RIF) regressions applied along the earnings distribution, coupled with data from a novel multi-topic household survey rich in details about entrepreneurship, to identify what proportion of the gender gap in business profits can be attributed to: (i) differences in average characteristics of profit-generating factors (composition effect) and (ii) gender differences in the returns to these factors (structure effect). We find that 59.8% of the mean gender gap is explained by gender differences in the levels of observable attributes, with the remaining 40.2% attributable to the lower returns to observable attributes obtained by female owners, i.e., female structural disadvantage. The composition effect is primarily driven by female owners’ role as the primary caregiver in most households and a lack of capital. The female structural disadvantage can largely be attributed to female owners’ heightened perception of sexual hostility in the work environment and non-cognitive skills related to entrepreneurship (perseverance in challenging tasks and environments, optimism, and passion for work). When looking along the distribution, capital stock appears to be a primary driver of the composition effect except in the bottom quintile of firms. In contrast, caregiving responsibilities are a driver of the composition effect in the bottom three quintiles only. Differences in the returns to capital appear to be a very significant driver of the female structural disadvantage in the bottom quintile.Non-PRIFPRI1; 1 Fostering Climate-Resilient and Sustainable Food Supply; 3 Building Inclusive and Efficient Markets, Trade Systems, and Food Industry; G Cross-cutting gender theme; Capacity Strengthening; CRP2EPTD; PHND; PIMCGIAR Research Program on Policies, Institutions, and Markets (PIM

    Responding to the times: Adapting an evaluation study during a dual pandemic

    This paper is a critical essay to discuss an original methodological design for an equity school evaluation in diverse-by-design schools. The evaluation was to gather a broad swathe of data necessary to provide detailed insights on diverse-by-design schools in diversity, equity, and inclusion (DEI) practices. We chronicle and critically explore the methodological pivots generated by the research team as we conducted this research against the backdrop of both the COVID-19 pandemic and US nationwide protests in response to the murder of George Floyd and countless other Black people at the hands of the police. We challenge our own use of equity in our research design by centering school communities through agency of partnership

    Background The impact of the COVID-19 pandemic on paediatric populations varied between high-income countries (HICs) versus low-income to middle-income countries (LMICs). We sought to investigate differences in paediatric clinical outcomes and identify factors contributing to disparity between countries.Methods The International Severe Acute Respiratory and Emerging Infections Consortium (ISARIC) COVID-19 database was queried to include children under 19 years of age admitted to hospital from January 2020 to April 2021 with suspected or confirmed COVID-19 diagnosis. Univariate and multivariable analysis of contributing factors for mortality were assessed by country group (HICs vs LMICs) as defined by the World Bank criteria.Results A total of 12 860 children (3819 from 21 HICs and 9041 from 15 LMICs) participated in this study. Of these, 8961 were laboratory-confirmed and 3899 suspected COVID-19 cases. About 52% of LMICs children were black, and more than 40% were infants and adolescent. Overall in-hospital mortality rate (95% CI) was 3.3% [=(3.0% to 3.6%), higher in LMICs than HICs (4.0% (3.6% to 4.4%) and 1.7% (1.3% to 2.1%), respectively). There were significant differences between country income groups in intervention profile, with higher use of antibiotics, antivirals, corticosteroids, prone positioning, high flow nasal cannula, non-invasive and invasive mechanical ventilation in HICs. Out of the 439 mechanically ventilated children, mortality occurred in 106 (24.1%) subjects, which was higher in LMICs than HICs (89 (43.6%) vs 17 (7.2%) respectively). Pre-existing infectious comorbidities (tuberculosis and HIV) and some complications (bacterial pneumonia, acute respiratory distress syndrome and myocarditis) were significantly higher in LMICs compared with HICs. On multivariable analysis, LMIC as country income group was associated with increased risk of mortality (adjusted HR 4.73 (3.16 to 7.10)).Conclusion Mortality and morbidities were higher in LMICs than HICs, and it may be attributable to differences in patient demographics, complications and access to supportive and treatment modalities

    Respiratory support in patients with severe COVID-19 in the International Severe Acute Respiratory and Emerging Infection (ISARIC) COVID-19 study: a prospective, multinational, observational study

    Background: Up to 30% of hospitalised patients with COVID-19 require advanced respiratory support, including high-flow nasal cannulas (HFNC), non-invasive mechanical ventilation (NIV), or invasive mechanical ventilation (IMV). We aimed to describe the clinical characteristics, outcomes and risk factors for failing non-invasive respiratory support in patients treated with severe COVID-19 during the first two years of the pandemic in high-income countries (HICs) and low middle-income countries (LMICs). Methods: This is a multinational, multicentre, prospective cohort study embedded in the ISARIC-WHO COVID-19 Clinical Characterisation Protocol. Patients with laboratory-confirmed SARS-CoV-2 infection who required hospital admission were recruited prospectively. Patients treated with HFNC, NIV, or IMV within the first 24 h of hospital admission were included in this study. Descriptive statistics, random forest, and logistic regression analyses were used to describe clinical characteristics and compare clinical outcomes among patients treated with the different types of advanced respiratory support. Results: A total of 66,565 patients were included in this study. Overall, 82.6% of patients were treated in HIC, and 40.6% were admitted to the hospital during the first pandemic wave. During the first 24 h after hospital admission, patients in HICs were more frequently treated with HFNC (48.0%), followed by NIV (38.6%) and IMV (13.4%). In contrast, patients admitted in lower- and middle-income countries (LMICs) were less frequently treated with HFNC (16.1%) and the majority received IMV (59.1%). The failure rate of non-invasive respiratory support (i.e. HFNC or NIV) was 15.5%, of which 71.2% were from HIC and 28.8% from LMIC. The variables most strongly associated with non-invasive ventilation failure, defined as progression to IMV, were high leukocyte counts at hospital admission (OR [95%CI]; 5.86 [4.83-7.10]), treatment in an LMIC (OR [95%CI]; 2.04 [1.97-2.11]), and tachypnoea at hospital admission (OR [95%CI]; 1.16 [1.14-1.18]). Patients who failed HFNC/NIV had a higher 28-day fatality ratio (OR [95%CI]; 1.27 [1.25-1.30]). Conclusions: In the present international cohort, the most frequently used advanced respiratory support was the HFNC. However, IMV was used more often in LMIC. Higher leucocyte count, tachypnoea, and treatment in LMIC were risk factors for HFNC/NIV failure. HFNC/NIV failure was related to worse clinical outcomes, such as 28-day mortality. Trial registration This is a prospective observational study; therefore, no health care interventions were applied to participants, and trial registration is not applicable

    Introduction: Acute kidney injury (AKI) has been identified as one of the most common and significant problems in hospitalized patients with COVID-19. However, studies examining the relationship between COVID-19 and AKI in low- and low-middle income countries (LLMIC) are lacking. Given that AKI is known to carry a higher mortality rate in these countries, it is important to understand differences in this population. Methods: This prospective, observational study examines the AKI incidence and characteristics of 32,210 patients with COVID-19 from 49 countries across all income levels who were admitted to an intensive care unit during their hospital stay. Results: Among patients with COVID-19 admitted to the intensive care unit, AKI incidence was highest in patients in LLMIC, followed by patients in upper-middle income countries (UMIC) and high-income countries (HIC) (53%, 38%, and 30%, respectively), whereas dialysis rates were lowest among patients with AKI from LLMIC and highest among those from HIC (27% vs. 45%). Patients with AKI in LLMIC had the largest proportion of community-acquired AKI (CA-AKI) and highest rate of in-hospital death (79% vs. 54% in HIC and 66% in UMIC). The association between AKI, being from LLMIC and in-hospital death persisted even after adjusting for disease severity. Conclusions: AKI is a particularly devastating complication of COVID-19 among patients from poorer nations where the gaps in accessibility and quality of healthcare delivery have a major impact on patient outcomes

    Thrombotic and hemorrhagic complications of COVID-19 in adults hospitalized in high-income countries compared with those in adults hospitalized in low- and middle-income countries in an international registry

    Background: COVID-19 has been associated with a broad range of thromboembolic, ischemic, and hemorrhagic complications (coagulopathy complications). Most studies have focused on patients with severe disease from high-income countries (HICs). Objectives: The main aims were to compare the frequency of coagulopathy complications in developing countries (low- and middle-income countries [LMICs]) with those in HICs, delineate the frequency across a range of treatment levels, and determine associations with in-hospital mortality. Methods: Adult patients enrolled in an observational, multinational registry, the International Severe Acute Respiratory and Emerging Infections COVID-19 study, between January 1, 2020, and September 15, 2021, met inclusion criteria, including admission to a hospital for laboratory-confirmed, acute COVID-19 and data on complications and survival. The advanced-treatment cohort received care, such as admission to the intensive care unit, mechanical ventilation, or inotropes or vasopressors; the basic-treatment cohort did not receive any of these interventions. Results: The study population included 495,682 patients from 52 countries, with 63% from LMICs and 85% in the basic treatment cohort. The frequency of coagulopathy complications was higher in HICs (0.76%-3.4%) than in LMICs (0.09%-1.22%). Complications were more frequent in the advanced-treatment cohort than in the basic-treatment cohort. Coagulopathy complications were associated with increased in-hospital mortality (odds ratio, 1.58; 95% CI, 1.52-1.64). The increased mortality associated with these complications was higher in LMICs (58.5%) than in HICs (35.4%). After controlling for coagulopathy complications, treatment intensity, and multiple other factors, the mortality was higher among patients in LMICs than among patients in HICs (odds ratio, 1.45; 95% CI, 1.39-1.51). Conclusion: In a large, international registry of patients hospitalized for COVID-19, coagulopathy complications were more frequent in HICs than in LMICs (developing countries). Increased mortality associated with coagulopathy complications was of a greater magnitude among patients in LMICs. Additional research is needed regarding timely diagnosis of and intervention for coagulation derangements associated with COVID-19, particularly for limited-resource settings
