New advances in RSV: Is prevention attainable?

Respiratory syncytial virus (RSV) is a major cause of lower respiratory tract infection (LRTI), hospitalization, and mortality in infants and young children globally. The greatest burden of severe disease and mortality occurs in low-middle income countries (LMICs), with large and vulnerable childhood populations. The highest rates of RSV-hospitalization occur in healthy-term infants under 3 months of age. Preterm infants, children with chronic lung disease of prematurity, Down's syndrome, congenital heart disease, or immunodeficiency also have a higher risk of severe RSV-LRTI. Early-life RSV-LRTI has also been associated with chronic sequelae, including recurrent LRTI, recurrent wheezing, asthma, and lung function impairment. A RSV pre-fusion (F) maternal vaccine and long-acting monoclonal antibody (nirsevimab) have been licensed for the prevention of RSV-LRTI in infants and young children. Studies show high efficacy and effectiveness particularly for preventing severe RSV-LRTI. Maternal RSV vaccine given at 24-36 weeks of pregnancy was effective in preventing RSV medically attended LRTI and severe RSV-LRTI through 6 months after birth in a phase 3 study conducted in 18 countries over two RSV seasons. Vaccination was safe with no significant difference in adverse events between infants born to mothers who received RSV preF vaccine compared to placebo. A numerical imbalance in preterm births that occurred predominantly in South Africa, unrelated to vaccine timing or gestational age at vaccination and unassociated with mortality, coincided with COVID-19 delta and omicron waves. Nirsevimab, given as a single dose prior or during the RSV season, had high efficacy in preventing RSV-LRTI hospitalization in infants in preterm and in full-term infants, as well as in young children with underlying conditions through 150 days post administration in phase 2 and 3 trials. High effectiveness against hospitalization or severe disease in infants and in at-risk children up to 2 years of age has also been reported in several countries where implementation has occurred. RSV-LRTI is now a preventable disease in infants and young children. Rapid implementation of these highly effective interventions has occurred in many high-income countries, but access remains very limited in LMICs. Access to such RSV preventive interventions is urgently needed for all children to strengthen child health and promote global equity.

Emerging integrase resistance in an international perinatal virtual clinic.

The aim of this study was to identify the prevalence of emergent integrase drug resistance mutations (INSTI-DRMs) in international referrals to a perinatal virtual clinic (PVC). A retrospective cohort study. Monthly multidisciplinary PVC reviewing complex case management for children and adolescents with perinatally acquired HIV (CAWHIV). One hundred fourteen cases referred for virological failure between October 2018 and January 2024. Data collected included age, sex, weight, country of residence, antiretroviral therapy (ART) history, HIV viral load, CD4+ cell count, and comorbidities. Resistance mutations were interpreted using the Stanford HIV Drug Resistance database with emergent major INSTI-DRMs described. Of 114 referrals, 103 (90%) had resistance sequences available. Prior INSTI exposure was documented in 61/103 (59%) with 19/61 (31%) having INSTI-DRMs. For these 19, median (IQR) age was 11 years (6-14), weight 25 kg (17-50), CD4+ cell count 485 cells/μl (153-805), and viral load 84 000 copies/ml (2380-137 000). Twelve of 19 (65%) were from low/middle-income countries (LMIC), 6/19 (32%) had current AIDS diagnoses with 14/19 (74%) referred from 2022 onwards. There were a median three prior regimens with 13/19 (68%) having at least 3 class resistance. Two developed INSTI-DRMs on first-line dolutegravir (DTG)-based ART, 17 on second+ line therapy. PVC recommendations were for tenofovir+ lamivudine/emtricitabine (six split adult tablets) with boosted darunavir [19; six twice daily (b.i.d.)], with b.i.d. DTG (6), plus fostemsavir (1) and ibalizumab (1). Although uncommon, INSTI resistance is emerging, mainly in highly treatment experienced CAWHIV from LMIC, highlighting the global need for access to boosted protease inhibitors and novel classes, including formulations for children less than 35 kg.

Gender Differences in Years of Life Lost resulting from the 2015 Gorkha Earthquake in Nepal

Abstract Background Nepal has a history of regular natural hazards, including significant earthquakes and floods. Previous studies have shown that females, particularly younger females, are more likely to die due to disasters compared to males. This study aimed to explore gender differences in mortality - measured in Years of Life Lost (YLL) - caused by the 2015 Gorkha earthquake across 41 districts of Nepal. Methods Mortality counts were derived from the Nepal Police Report. YLL was estimated by multiplying mortality counts (stratified by age, gender, and district) by age-conditional life expectancy from the 2019 Global Burden of Disease reference life table. Both absolute numbers and rates of YLL per 100,000 population were calculated. YLL per deaths, stratified by age-gender-and-location, were estimated and compared. Male-to-female YLL rate ratios were estimated as well, and compared across districts. Results The 2015 Gorkha earthquake resulted in 8,950 deaths (females: 56.1% versus males: 43.9%), accounting for 526,617 YLL. Males had a slightly higher number of YLL per death (59.2) compared to females (58.5); this is mainly due to the different number of deaths between males and females. YLL per deaths ranged from 65.4 (Rautahat district) to 0 (in several districts) among males and, from 65.3 (Rautahat district) to 0 (in several districts) among females. The YLL rate per 100,000 population was higher for females (3,158 per 100,000) than for males (2,575 per 100,000). Approximately 40% of the districts had male-to-female YLL rate ratios of less than one, which can be partly explained by the gender distribution of the population at rik of dying due to earthquake. Conclusions The study found relatively higher YLL per death for males and higher YLL rates for females. This underscores the necessity to further investigate the factors that contribute to fatalities from earthquakes, especially in lower middle income countries such as Nepal. Key messages • Gender disparities in mortality following the 2015 Gorkha earthquake in Nepal were addressed using Years of Life Lost (YLLs); males had higher YLL per death, while females had higher YLL rates. • Exploring the factors that contribute to earthquake-related fatalities should be a priority for disaster mitigation strategies.

Equity and representation in cardiology research: a comprehensive analysis of authorship from low and low-middle income countries in leading cardiology journals

Abstract Background Cardiovascular disease is the leading global cause of mortality, with low-income and low-middle-income countries (LICs/LMICs) bearing a disproportionate burden. Despite this, research output is skewed towards affluent regions. This study aims to assess the authorship trends from LICs/LMICs in cardiology research in 5 of the leading cardiology journals. Methods PubMed authorship affiliation was obtained from 2000-2022 in (1) Journal of the American College of Cardiology (JACC), (2) Circulation, (3) Journal of the American Medical Association (JAMA) Cardiology, (4) Nature Reviews Cardiology, (NRC) and (5) European Heart Journal (EHJ). Countries were classified according to the World Bank. Results 62873 original research, clinical cases, editorials, and reviews were published in all five journals (2000-2022). The percentage of articles with at least one author affiliated with an institution from a LIC or LMIC was 1.03% (N=652): 0.96% (N=190) in JACC, 0.82% (N=198) in Circulation, 2.42% (N=51) in JAMA Cardiology, 0.84% (N=22) in NRC, and 1.33% (N=191) in EHJ. There has been an increase in the representation of authorship from LICs and LMICs in the last decade. However, the distribution of authorship between LMICs and LICs is uneven, represented mainly -by Mozambique, Uganda, Sudan, and Ethiopia for LICs, and India, Iran, Egypt, Pakistan and Lebanon for LMICs. Discussion: Our findings reveal an underrepresentation of authors from institutions from LICs and LMICs in these 5 leading cardiology journals. Efforts to enhance funding, access, and inclusion of authors from LICs and LMICs are imperative to advance global cardiovascular outcomes and promote equity in medical research.

AB-HFPEF score: A new and improved HFpEF prediction tool for the Indian patient

Abstract Background/Introduction Heart failure with preserved ejection fraction (HFpEF) remains underdiagnosed in low-middle income countries including India. The simple and validated H2FPEF score has largely replaced the diagnostic need for invasive right heart catheterization. The score has therapeutic implications by stratifying patients into low, intermediate and high-risk groups. The relevance of this score is yet to be ascertained in the Indian population. Purpose We hypothesized that the H2FPEF score may fall short in accurately predicting HFpEF in our population, thus warranting a new score. Methods We conducted a prospective observational study over one year at the out-patient department of a tertiary-care hospital in India. Patients presenting with clinical features of heart failure were screened and enrolled in the study. Demographic, clinical, laboratory and echocardiographic details were recorded by the principal investigator using an online data collection tool. Patients were stratified into ‘low risk’, ‘intermediate risk’ and ‘high risk’ probabilities, with respective cut-off values of 0-3, 4-6, and 7-9 using the point-based score, and <30%, 30-59%, and >60% via the continuous model of H2FPEF score. Pearson’s chi-square test identified significant risk factors that were purposed into a novel AB-HFPEF score. Cohen’s kappa correlation determined the degree of agreement in the risk stratifications of the H2FPEF and the AB-HFPEF score, using the continuous scoring model as the reference. Results Among the 189 patients screened, 137 were enrolled in the study. The baseline characteristics are recorded in Table 1. Pedal edema and uncontrolled hypertension were noteworthy risk factors. A novel AB-HFPEF score was subsequently designed and scored as follows: Age (> 60 years) - 1, BMI (> 30 kg/m2) - 2, uncontrolled Hypertension (>140/90 mmHg) - 1, Filling pressure (E/e' > 9) - 1, Pulmonary Artery Systolic Pressure (> 35 mmHg) - 1, pedal Edema - 1, atrial Fibrillation - 3. Receiver operating characteristics (ROC) curve analysis demonstrated an area under the ROC curve (AUC) of 0.85 (95%CI, 0.78 to 0.91) for ‘low risk’ strata and 0.87 (95%CI, 0.81 to 0.93) for ‘high risk’ strata. The optimal stratification was 0-2, 3-4, and 5-10 points for the ‘low risk’, ‘intermediate risk’, and ‘high risk’ respectively. There was a moderate agreement of the AB-HFPEF score with the reference score (κ = 0.48 (95% CI, 0.36 to 0.60), p < 0.001), while the point-based H2FPEF score had only a slight agreement (κ = 0.15 (95% CI, 0.05 to 0.25), p < 0.001), as illustrated in Figure 1. Conclusion(s) The novel AB-HFPEF score performs better risk stratification in Indian patients with HFpEF as compared to the point-based H2FPEF score. We hence propose the AB-HFPEF score as an instrument for tailored cardiology care in the Indian demographic, laying the cornerstone for larger validation and prognostication studies.Table 1:Baseline characteristicsFigure 1:Heat Map Illustration

Survival of pediatric patients with ependymoma in a tertiary cancer center in Rio de Janeiro, Brazil

IntroductionEpendymoma is the third most frequent central malignant nervous system tumor in the pediatric age group. There is scarce data in the literature on survival of these patients, especially in upper and lower middle-income countries. We aimed to describe the clinical and demographic characteristics, treatment, and outcome of pediatric patients with ependymoma admitted to a public cancer hospital.MethodsRetrospective analysis of medical records of patients with ependymoma, admitted to the Pediatric Oncology department (0-20 years) during the period of 2000-2022. Data on patient, disease characteristics, and treatment were analyzed. Overall survival (OS) was calculated using the Kaplan-Meier method.ResultsSeventy-two patients were evaluated; median age at diagnosis was 6.5 years (range: 1-20), 63% were male, 54% of the tumors were in the posterior fossa (PF-EPN), 45% were classified as WHO grade 3, and 68% were operated on in other institutions before referral. Regarding treatment, 72% underwent radiotherapy and 33% of patients underwent chemotherapy. Almost 70% percent of the patients had relapses. The median follow-up time was 5.2 years (Range: 0,1-21,4). The OS in 5 years was 67%. Totally resected tumors had OS in 5 years of 88% (p: 0.028).ConclusionThe results achieved in this series show a survival gap between UMIC and HIC. Relapses occurred mainly in the first ten years and then reached a plateau, with the majority of patients experiencing endocrinological and neurological sequelae.

Exploring the complexity, treatment challenges, and outcomes in pediatric nodular lymphocyte predominant Hodgkin lymphoma: a perspective from a low–middle-income country

BackgroundIn children, nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is an uncommon subtype of Hodgkin lymphoma. Given the lack of data on the best chemotherapy regimen, there is a knowledge gap in best management.MethodsThis retrospective study included all pediatric patients with NLPHL diagnosed and treated at the Children’s Cancer Hospital, Egypt (2007–2018). We analyzed the clinical characteristics, and treatment outcome according to disease stage (early and advanced), treatment strategy (doxorubicin, bleomycin, vinblastine, and dacarbazine [ABVD] or rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone [R-CHOP] and explored the prognostic factors for progression-free survival.ResultsThe median age at diagnosis was 12 years; 40 (68%) patients had early-stage disease, and 19 (32%) had advanced-stage disease. The median follow-up was 70 months; the 5-year EFS and OS were 75% and 97%, respectively. The 5-year EFS was 78% for early-stage disease and 60% for advanced-stage disease; the 5-year OS was 100% for early-stage disease and 88% for advanced-stage disease. The patients who underwent R-CHOP had a better 3-year EFS (100%) compared with those who underwent ABVD (65%) regimen (P = 0.01). Seventeen (25%) patients relapsed: 9/40 (22%) had early-stage disease, and 8/19 (42%) had advanced-stage disease. Splenic involvement, mediastinal disease, extranodal disease, and slow early response were independent predictors of relapse risk.ConclusionPediatric patients with early-stage NLPHL have an excellent prognosis, with a 5-year OS of 100%. However, those with advanced stages had a high relapse rate. R-CHOP was associated with a better response and relapse-free rate than ABVD.

Frugal innovation and entrepreneurial university: a case study of African first development university in Africa

The concept of frugal innovation has gained significant traction in low middle-income countries due to its potential to contribute to sustainable development goals (SDGs). This study examines the role of universities in promoting frugal innovation and their capacity to drive socio-economic development through entrepreneurial initiatives. The objective is to explore how universities can serve as both entrepreneurial and development-focused institutions and to develop a conceptual framework to guide their efforts. The study utilizes an exploratory single case study methodology, focusing on the American University of Nigeria (AUN), a leading institution in Nigeria known for its development and entrepreneurship programs. Drawing on data from the AUN THE global impact ranking 2024, the results of the study indicate that the ability of a university to effectively manage technology and skills transfer in frugal innovations is influenced by six university capabilities, and the generation of frugal innovations is moderated by policy and innovation ecosystems involving government agencies, regulatory bodies, and policymakers. This study contributes to the existing body of knowledge by initiating a discussion on how development and entrepreneurship can support frugal innovation, and offers practical insights to inspire other universities to develop their own models for societal and economic impact. The study underscores the necessity of integrating “development” into the vision of universities, particularly in low middle-income and developing economies, and emphasizes the significance of universities embracing both entrepreneurial and development-focused roles. The findings highlight the potential of universities in advancing sustainable development goals, particularly in low middle-income and developing economies, as they work towards meeting the global SDGs by 2030.

Unveiling the Burden of Nephrolithiasis in Low- and Lower-Middle Income Countries: A Review on Its Presentation, Risk Factors, Treatment Practices, and Future Directions

Background: Nephrolithiasis, or kidney stone disease, presents a significant global health burden, with global incidence rates and treatment practices varying widely. This study aims to discuss the epidemiology, risk factors, treatment modalities, and challenges for nephrolithiasis in the lower half of the World Bank rankings; that is, in low- and lower-middle-income countries. Methods: A comprehensive literature review was conducted using PubMed for each country on the list, focusing on studies published from January 2000 onwards and reporting data on prevalence, risk factors, treatment practices, and economic implications. Results: Nephrolithiasis represents a significant burden for healthcare systems, with noteworthy geographical variability in prevalence possibly dependent on socioeconomic status and gender. Risk factors include dietary habits, climate, pollution, and infectious diseases. Treatment practices in some regions still rely on open surgery due to limited access to advanced endourological techniques, while other regions demonstrate high proactivity in research. The burden is exacerbated by inadequate healthcare infrastructure and training. Conclusions: Addressing nephrolithiasis in challenging economic circumstances requires targeted interventions, including improved access to modern treatment methods, enhanced training for healthcare professionals, and better socioeconomic and environmental conditions. Future research should focus on region-specific strategies and the development of sustainable healthcare solutions.

Systems modelling and simulation to guide targeted investments to reduce youth suicide and mental health problems in a low–middle-income country

BackgroundDespite suicide’s public health significance and global mental health awareness, current suicide prevention efforts show limited impact, posing a challenge for low- and middle-income countries. This study aimed to develop a dynamic simulation model that could be used to examine the potential effectiveness of alternative interventions for reducing youth mental health problems and suicidal behavior in Bogotá, Colombia.MethodsA system dynamics model was designed using a participatory approach involving three workshops conducted in 2021 and 2022. These workshops engaged 78 stakeholders from various health and social sectors to map key mental health outcomes and influential factors affecting them. A model was subsequently developed, tested, and presented to the participants for interactive feedback, guided by a moderator. Simulation analyses were conducted to compare projected mental health outcomes for a range of intervention scenarios with projections for a reference scenario corresponding to business-as-usual.ResultsA total of 6670 suicide attempts and 347 suicides are projected among 7 − 17-year-olds from January 1, 2023, to early 2031 under the business-as-usual scenario. Mental health issues among 12 − 17-year-olds are projected to increase from 18.9% (2023) to 27.8% (2031), and substance use issues from 2.29 to 2.49% over the same period. School-based suicide prevention and gatekeeper training are the most effective strategies, reducing total numbers of suicide attempts and suicides by more than 20% (i.e., compared to business-as-usual). However, discontinuous funding significantly hinders these effective suicide prevention efforts.ConclusionsSystems modelling is an important tool for understanding where the best strategic financial and political investments lie for improving youth mental health in resource-constrained settings.

Bacterial contamination of platelets concentrates in a lower middle-income country: Data from a single tertiary care hospital

BackgroundTransfusion of bacterially contaminated platelets may cause life threatening sepsis in the recipients. Cost of platelet screening is a major challenge for low middle income countries (LMICs). In this study, we evaluated the frequency of bacterial contamination in the platelet units (PUs) and the outcome of transfusing such platelets to the patients in a single institute at Pakistan. Material and methodsDuring 2018–2022, whole blood-derived (WB-PU) and apheresis platelets (AP) were screened by BacT-ALERT® automated system. Single sample from each AP and samples from ≤ 5 WB-PUs were pooled and cultured within 24 h-post collection. An initial positive signal was followed by re-culture, Gram’s staining, pool resolution and bacterial identification. Results were interpreted as ‘confirmed positive’ or ‘indeterminate’ and ‘confirmed negative’ based on differences in initial-reactive and final results. ResultsA total of 84246 PUs (476 AP and 83770 WB-PU) was screened, and 239 (0.28 %) culture bottles were positive on day one. Individual cultures were performed on 1378 PUs (239 bottles) for pool resolution. Seven of 1378 (0.5 %) PUs were ‘confirmed positive’ while 1371 (99.4 %) were ‘indeterminate’. No bacterial growth was observed in 82868 (82392 WB-PU and 476 AP) of 84246 (98.3 %). Overall bacterial contamination rate was low at 1 in 12000 PUs approximately. Seven patients were transfused with contaminated PUs but no transfusion reaction was observed. ConclusionAn insignificant risk of bacterial contamination was observed in this study but remains a concern for patient safety. LMICs need cost effective but efficient techniques to screen platelets for the presence of bacteria.

Cost-effectiveness of Procalcitonin (PCT) guidance for antibiotics management of adult sepsis patients in the Egyptian context

BackgroundSepsis, which is described as a life-threatening organ malfunction brought on by an unbalanced host response to infection, continues to be a significant healthcare issue that affects millions of individuals each year. It is well-known that sepsis can affect anyone around the world, but the employed survey results showed that there are significant regional variations in sepsis incidence as well as mortality rates. Although there are no definite estimates for Egypt, the highest rates were in Low-Middle-Income Countries (LMICs).Procalcitonin (PCT) is a host response marker with high specificity for bacterial infections, unlike C-reactive protein (CRP) or white blood cell count (WBC), which represent the traditional methods of detecting inflammation and infection. Its dynamic profile and superior prognostic prediction make it invaluable for assessing response to antibiotic treatment and improving clinical care for sepsis patients.Our main purpose was to evaluate the cost-effectiveness of PCT guidance compared to no PCT guidance in the antibiotic management of adult sepsis patients according to the Egyptian context.MethodsWe developed a decision tree model to compare the PCT-guided antibiotic management duration endpoint versus the conventional laboratory culture-based antibiotic management in adult sepsis patients. We employed the“Delphi technique” to reach a satisfactory consensus regarding the resources attributed to each compared alternative. The primary measure of the study was the additional cost associated with each Quality-Adjusted Life Year (QALY) gained by sepsis survivors over a one-year time horizon.Base-case, deterministic and probabilistic sensitivity analyses were conducted using TreeAge, Software.ResultsBase-case analysis showed no dominance for either alternative and resulted in an Incremental Cost-Effectiveness Ratio (ICER) value of 297,783.57 Egyptian Pounds per Quality Adjusted Life Year (L.E/QALY) in favor of the PCT guidance alternative, Deterministic sensitivity analysis revealed that the highest impact magnitudes on ICER reside with seven input parameters, the top two parameters that had the most significant influence were the costs of ICU stay with and without PCT guidance. The CEAC showed a slightly higher probability in terms of acceptability in favor of the no PCT guidance choice along the WTP scale till reaching equal probabilities at the willingness-to-pay (WTP) value point of 390,000 (state currency) after which the - probability supports the PCT guidance choice. ConclusionsIn the Egyptian context, PCT guidance has no cost-effectiveness domination over no PCT guidance in Antibiotics management for adult sepsis patients. This may be attributed to the high cost of PCT investigation that shall be resolved by standardization of its cost when applying the approach of DRG cost packages.

The radiological primary survey: A systematic approach and guide to reading torso computed tomography images in trauma for surgeons

Background Trauma is a disease where time is of the essence. In many lower middle-income countries, definitive management and planning for trauma patients are often delayed after working hours because of either a lack of technicians to perform computed tomography (CT) scans or a lack of radiologists to interpret them. These lacunae can be bridged if more and more surgeons become confident in interpreting trauma CT images. Method In this narrative review, written in a ‘how to do it’ manner, we describe a way of doing a structured and quick ‘radiological primary survey’ of the torso CT, which we believe will help quickly identify major injuries systematically, thereby avoiding delays in management and forming a care plan. The method has been developed by a team of trauma surgeons and radiologists and stems from the DRS ABCDE technique used in interpreting trauma chest X-rays. Result The DRS ABCDE extrapolated to the trauma torso CT includes the following steps- Details, WRAP (W-windowing, R-Region, A-Axis, P-Phase), S- the Scout film, Airway, Breathing, Circulation, Disability and Extras. Conclusion The review will enable resident trainees and trauma care professionals to interpret trauma CTs using a structured approach.

Neurological Complications and Outcomes in Critically Ill Patients With COVID-19: Results From International Neurological Study Group From the COVID-19 Critical Care Consortium

Background In this COVID-19 Critical Care Consortium (CCCC) sub-study, we qualified neurological complications associated with SARS-CoV2 infection. Methods The CCCC is an international, multicenter study. Eligible patients were COVID-19 patients admitted to intensive care units (ICU) across 23 centers between 1/7/2020 to 6/23/2022. Incidence of neurological complications was estimated as number of events per hospital days and per admission using Poisson regression. Associations between neurological complications and risk factors were assessed using multivariable Poisson regression. Results 713 patients were included. Median age = 56 years (interquartile range (IQR) = 45-65). Neurological complications reported in 61/480 patients (12.7%) with the majority being ischemic stroke (2.9%), intracranial hemorrhage (ICH) (2.8%), and seizures (2.6%). Multivariable analysis for neurological complications per admitted days showed comorbid neurological conditions (incidence rate ratio (IRR) = 6.35, 2.57-15.7) were an independent risk factor for ischemic stroke. Extracorporeal membrane oxygenation (IRR = 5.32, 1.52-18.6), low-middle income countries (LMIC) vs high income countries (HIC) (IRR = 4.70, 1.62-13.7), and age >55 (IRR = 3.66, 1.23-10.9) were independent risk factors for ICH. Co-morbid neurological conditions (IRR = 3.43, 1.11-10.6), LMIC vs HIC (IRR = 8.69, 2.15-35.2), July-December 2020 vs January-June 2020 (IRR = 0.17, 0.04-0.69) and age >55 (IRR = 4.05, 1.15-14.3) were independent risk factors for seizure. Conclusions Decision-making should incorporate salient risk factors to inform management of SARS-CoV2 infection and avoid neurological complications.

A global snapshot on health systems capacity for detection, monitoring, and management of acute kidney injury: A multinational study from the ISN-GKHA.

Acute kidney injury (AKI) is a significant cause of morbidity and mortality, especially in low and lower-middle income countries. Data from the third iteration of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) were used to evaluate the organization of structures and services for the provision of AKI care in world countries and ISN regions. An international survey of key stakeholders (clinicians, policymakers, and patient advocates) from countries affiliated with the ISN was conducted from July to September 2022 to assess structures and services for AKI care across countries. Main findings of the study show that overall, 167 countries or jurisdictions participated in the survey, representing 97.4% of the world's population. Only 4% of countries had an AKI detection program based on national policy or guideline, and 50% of these countries used a reactive approach for AKI identification (i.e., cases managed as identified through clinical practice). Only 19% of national governments recognized AKI as a healthcare priority. Almost all countries (98% of the countries surveyed) reported capacity to provide acute hemodialysis (HD) for AKI, but in 31% of countries, peritoneal dialysis (PD) was unavailable for AKI. About half of all countries (44% of countries surveyed) provided acute dialysis (HD or PD) via public funding, but funding availability varied across ISN regions, including less than a quarter of countries in Oceania and South East Asia (17%) and Africa (24%) and highest availability in Western Europe (91%). Availability increased with the increasing country income level. Initiatives have been developed to propose and promote optimal care for AKI (including the ISN 0-by-25 initiative), but capacity for optimal AKI care remains low, particularly in low- and lower-middle-income countries. Concerted efforts by the global community are required to close these gaps, to improve AKI outcomes across the world.

Current situation of neuropathology in Central America

The present situation of neuropathology practice in the Central American region has not been addressed in the past. These are low middle-income countries, and therefore, many do not have a basic immunohistochemistry panel. Cytogenetics and molecular studies are not available in most of Central America. Pediatric brain tumors are diagnosed either by anatomical pathologists or by pediatric pathologists. Access to a weakly Latin American Tumor Board is available to consult cases, but most countries do not participate in these expert meetings. The most recent World Health Organization brain tumor book has a very broad molecular classification of pediatric brain tumors. All these factors make it very difficult to properly diagnose pediatric brain tumors in the region, and this impacts the treatment and overall survival of children with brain tumors.

Less invasive surfactant administration with specially designed semirigid catheter: Experience from a tertiary level neonatal unit of a lower middle-income country.

Clinical outcomes of 74 preterm neonates, who received surfactant replacement therapy (SRT), were collected retrospectively, to compare the following modes of administration: (1) less invasive surfactant administration (LISA) via a specially designed semirigid catheter (Surfcath), (2) INtubate-SURfactant-Extubate (INSURE) and (3) through endotracheal tube (ETT), in neonates requiring mechanical ventilation. The primary composite outcome of mortality or bronchopulmonary dysplasia (BPD) at 36 weeks' post-menstrual age was 41% in LISA, 38% in INSURE and 77% in ETT groups (p < 0.01), the difference being mainly due to the high incidence of mortality in the latter. LISA, via a specially designed semirigid catheter, was safe and feasible in preterm neonates.

Current Diagnosis of Bleeding Disorders in Lower Income Countries.

There have been considerable advances in diagnosing and treating bleeding disorders. But the scenario remains dismal in resource-constrained settings in low and lower-middle-income countries (LMICs). Seventy-five percent of the patients with inherited bleeding disorders do not get diagnosed in LMICs. In resource-constrained settings, infectious disease and malignancies take the major focus. Bleeding disorders do not get prioritised in LMICs, and this leads to underdiagnoses and suboptimal treatment. There are various challenges like financial status, inadequacy of health care infrastructure, lack of patient registry and lack of awareness across medical staff, general population and government stakeholders. The lack of skilled laboratory personnel and laboratory infrastructure for optimal bleeding disorder diagnosis adds on to the problem. World Federation of Hemophilia (WFH) has been at the forefront in developing strategies to overcome some of these inadequacies; however, more active participation of the stakeholders including patients, medical professionals and policy makers is the need of the hour. This review highlights the different challenges in LMICs in diagnosing bleeding disorders, the gap between high-income countries and LMICs and the possible strategies in closing the gap.

Intracranial pressure monitoring and treatment practices in severe traumatic brain injury between low-and middle-income countries and high-income countries: Data or dogma?

Background: Traumatic brain injury (TBI) is a major cause of morbidity and mortality worldwide. Intracranial pressure (ICP) monitoring forms the cornerstone of most severe TBI (sTBI) management guidelines, yet treatment practices vary between high income countries (HIC) and low/middle-income countries (LMICs). We sought to find the reasons for variation in ICP monitoring and treatment practices between neurosurgeons in low- and high-income countries. Methods: We developed a 34-item anonymous survey questionnaire on ICP monitoring and treatments, which was emailed to neurosurgeons of various neurosurgical societies (Africa, Asia, Europe, and North America) who manage TBI. Results: One hundred and six respondents from 23 countries completed the questionnaire. Sixty-nine were from Africa, 16 were from North America, 12 were from Western Europe, and 8 were from Asia. About 48.72% of respondents from LMICs versus 96.43% from HICs have had training on ICP use. Among practitioners who monitor ICP invasively in &lt;50% of patients that need it, 41.6% and 37.5% from LMIC cited availability and cost as the major constraints, versus 3.3% and 6.67%, respectively, in HIC. Only 7 (8.97%) from LMIC follow Brain Trauma Foundation guidelines all the time compared to 17.86% from HIC. When asked about their knowledge of randomized controlled trial(RCT), 78.57% of respondents from HIC versus 11.54% from LMIC knew about RCTs that tested the role of ICP monitoring in sTBI. Conclusion: Significant differences exist in ICP monitoring and treatment in patients with sTBI between high and LMICs. Cost and availability are the main determinants of ICP monitor usage. Practice pattern among the respondents was not completely supported by evidence.
