Background: One of the greatest challenges to conducting multicenter research studies in low and middle-income countries (LMICs) is the heterogeneity in regulatory processes across sites. Previous studies have reported variations in requirements with a lack of standardization in the Institutional Review Board (IRB) processes between centers, imposing barriers for approval, participation, and development of multicenter research.

Objectives: To describe the regulatory process, variability and challenges faced by pediatric researchers in LMICs during the IRB process of an international multicenter observational point prevalence study (Global PARITY).

Article Synopsis
  • - Hypertension is a leading cause of heart disease and death globally, and low-dose combination therapy using amlodipine, telmisartan, and chlorthalidone shows promise for safe and effective management according to a systematic review.
  • - The review analyzed randomized controlled trials (RCTs) to assess the effectiveness of this combination therapy, focusing on changes in blood pressure and adverse effects, finding three RCTs that met quality standards.
  • - Results indicated significant improvements in blood pressure control and a low risk of serious side effects; however, variations in dosages and control groups suggest further research is necessary to fully understand the long-term outcomes and factors influencing treatment responses.

The true global burden of paediatric critical illness remains unknown. Studies on children with life-threatening conditions are hindered by the absence of a common definition for acute paediatric critical illness (DEFCRIT) that outlines components and attributes of critical illness and does not depend on local capacity to provide critical care. We present an evidence-informed consensus definition and framework for acute paediatric critical illness.

Background: Reducing child mortality in low-income countries is constrained by a lack of vital statistics. In the absence of such data, verbal autopsies provide an acceptable method to determining attributable causes of death. The objective was to assess potential causes of pediatric postdischarge mortality in children younger than age 5 years (under-5) originally admitted for suspected sepsis using verbal autopsies.

While progress has been made to decrease mortality in children under age five, there continues to be a need for improvement in the treatment of children with congenital heart disease. Many of these patients require surgical correction and live in areas without the expertise of surgical teams. Research has shown that appropriate training is critical to ensure the best clinical outcomes.

Pediatric critical care medicine (PCCM), as it is practiced in high-income countries, is focused on specialized medical care for the most vulnerable pediatric patient populations. However, best practices for provision of that care globally are lacking. Thus, PCCM research and education programming can potentially fill significant knowledge gaps by facilitating the development of evidence-based clinical guidelines that reduce child mortality on a global scale.

With advances in pediatric and obstetric surgery, pediatric patients are subject to complex procedures under general anesthesia. The effects of anesthetic exposure on the developing brain may be confounded by several factors including pre-existing disorders and surgery-induced stress. Ketamine, a noncompetitive -methyl-d-aspartate (NMDA) receptor antagonist, is routinely used as a pediatric general anesthetic.

Within a short time, Coronavirus disease 2019 (COVID-19) has evolved into a pandemic spreading at a speed and scale that has been able to overwhelm even the most advanced health care systems quickly. Multiple guidelines published by organizations such as the WHO and US' CDC address the response to COVID-19 at the international, national, and local levels. Although these guidelines are meant to be globally accessible, implementing them is a challenge given the variability in the health care systems worldwide between low- and middleincome countries (LMIC) and high-income countries and even amongst different regions within each LMIC.

The goal of this study was to analyze the influence of corporate social responsibility on dividend pay-out while considering the role of corporate governance quality on mutual funds operating in Pakistan. This study used a two-step system generalized method of moments (GMM) to control not only endogeneity problems caused by inclusion of firm-specific variables, but also the endogeneity caused by dividend pay-out selection. The findings are that mutual funds that engage in higher levels of corporate social responsibility pay greater dividends.

Background: The burden of pediatric critical illness and resource utilization by children with critical illness in resource limited settings (RLS) are largely unknown. Without specific data that captures key aspects of critical illness, disease presentation, and resource utilization for pediatric populations in RLS, development of a contextual framework for appropriate, evidence-based interventions to guide allocation of limited but available resources is challenging. We present this methods paper which describes our efforts to determine the prevalence, etiology, hospital outcomes, and resource utilization associated with pediatric acute, critical illness in RLS globally.

Numerous animal models have been used to study developmental neurotoxicity associated with short-term or prolonged exposure of common general anesthetics at clinically relevant concentrations. Pediatric anesthesia models using the nonhuman primate (NHP) may more accurately reflect the human condition because of their phylogenetic similarity to humans with regard to reproduction, development, neuroanatomy, and cognition. Although they are not as widely used as other animal models, the contribution of NHP models in the study of anesthetic-induced developmental neurotoxicity has been essential.
