Comparing the Accuracy of ABCD-10 and SCORTEN in Predicting the In-Hospital Mortality of Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis: A Multi-Institutional Study from Central China

Background: The newly described ABCD-10 (age, bicarbonate, cancer, dialysis, 10% body surface area [BSA]) is a 5-item mortality prediction model for patients with Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN). It was developed in the United States, has at present been externally tested only in the United States, Spain, and Singapore, and remains to be validated in resource-restricted settings. We sought to compare the accuracy of ABCD-10 and Score of Toxic Epidermal Necrolysis (SCORTEN) in predicting in-hospital mortality in a cohort from central China. Due to disease progression affecting the accuracy of the prediction model during hospitalization, for example, higher predictive accuracy of SCORTEN based on parameters collected on day 3 of hospitalization, we also assessed the overall predictive value of ABCD-10 on days 1 and 3, respectively. Methods: A retrospective study was performed over a 10-year period (2010–2020) from 3 medical institutions in Wuhan. The performance of predictive models was assessed by both discrimination and calibration. Receiver-operating characteristic (ROC) curves, Hosmer-Lemeshow goodness-of-fit tests and calibration plots were used to evaluate the model discrimination and calibration. Results: Of 84 included patients, 11 (13.1%) did not survive. The discrimination power of ABCD-10 was not significantly different from that of SCORTEN (area under the curve: day 1, p > 0.05; day 3, p > 0.05). Although the calibration of ABCD-10 was good, it was inferior to SCORTEN as it underestimated total mortality (Hosmer-Lemeshow goodness-of-fit test: day 1, p = 0.17 vs. p = 0.63; day 3, p = 0.35 vs. p = 0.93). Besides, the performance of ABCD-10 was slightly better on day 3 relative to day 1. During hospitalization, bacteremia developed in 21 (25.0%) patients, which was associated with a higher risk of death in our cohort (odds ratio, 22.88; 95% CI, 4.38–119.40; p < 0.001). Conclusion: ABCD-10 showed acceptable overall performance, but revealed mortality underestimation and was inferior to the performance of SCORTEN. In consistence with SCORTEN, ABCD-10 was a better model when using values collected at day 3 of hospitalization relative to day 1.

Young Women with Breast Cancer in Resource-Limited Settings: What We Know and What We Need to Do Better.

Young women with breast cancer (YWBC) account for a variable proportion of patients diagnosed with breast cancer around the globe, with a higher prevalence in resource-limited settings than in high-income countries. This group represents a unique population that warrants special attention due to specific biological considerations and age-specific supportive care issues. This review aims to explore existing knowledge regarding YWBC’s needs, particularly in resource-restricted settings. To date, scarce information regarding the care of YWBC in resource-constrained countries is available, with most reports describing suboptimal care in terms of survivorship needs. Health care providers should implement actions to improve endocrine treatment adherence, referrals for fertility counseling and preservation, contraceptive use compliance, timely body image and sexual function interventions, comprehensive genetic risk assessments, and early quality of life and psychosocial health interventions. While high costs act as a barrier for optimal care in resource-limited settings, improving patient education represents a promising and cost-effective solution to improve patient care. Future research on developing tailored educational resources for YWBC in resource-limited settings should be considered a priority.

Implementation of first episode psychosis intervention in India – A case study in a low-and middle-income country

First Episode Psychosis (FEP) is a serious mental illness affecting adolescents and young persons. While many effective interventions are available, there has not been much research to understand the implementation of such interventions in India and other low- and middle-income countries (LMIC). We studied the implementation of an FEP intervention program in a specialist mental health facility in Chennai, India, using a well-established framework for doing so, the Consolidated Framework for Implementation Research (CFIR). We conducted 27 in-depth interviews with the service users (15 persons with FEP and 12 family caregivers of persons with FEP). We also conducted a focus group discussion with 8 service providers and in-depth interviews with 7 other service providers including those in the service management. A thematic analysis approach was used to identify emerging themes. First, we found CFIR effectively accommodated implementation challenges evident in LMICs; that is, it is transferable to LMIC settings. Second, we highlight barriers to implementation that include cost, limited human resources, cultural and professional hierarchy, divergence from evidence-based guidelines, and lack of awareness and stigma in the wider community. Third, we highlight facilitators for implementation such as, leadership engagement, the need for change that was recognized within the service, cosmopolitan perspectives derived from clinicians’ local and international collaborative experiences and expertise, compatibility of the intervention with the existing systems within the organization, accommodating the needs of the service users, and rapport developed by the service with the service users. Fourth, we propose a model of service delivery incorporating a task-sharing approach for first episode psychosis in resource restricted settings based on the feedback from the stakeholders.

A field study evaluating the humoral immune response in Mongolian sheep vaccinated against sheeppox virus.

Sheeppox is a transboundary disease of small ruminants caused by infection with the capripoxvirus sheeppox virus. Sheeppox is found in Africa, the Middle East and Asia and is characterized by fever, multifocal cutaneous raised lesions and death. Vaccination with live attenuated capripoxvirus (CPPV) strains is an effective and widely used strategy to contol sheeppox outbreaks; however, there are few reports of post-vaccination field surveillance studies. This study used a commercially available enzyme-linked immunosorbent assay (ELISA) to examine quantitative and temporal features of the humoral response of sheep vaccinated with a live-attenuated CPPV strain in Mongolia. Four hundred samples were tested using the ELISA commercial kit, and a subset of 45 samples were also tested with a virus neutralization test (VNT). There was substantial agreement between the VNT and ELISA tests. Antibodies to CPPV were detected between 40 and 262 days post-vaccination. There was no significant difference between serological status (positive/negative) and sex or age; however, an inverse correlation was found between the length of time since vaccination and serological status. Animals between 90 and 180 days post-vaccination were more likely to be positive than animals greater than 180 days post-vaccination. Our results show that a commercial CPPV ELISA kit is a robust and reliable assay for post-CPPV vaccination surveillance in resource-restricted settings and provide temporal parameters to be considered when planning sheeppox post-vaccination monitoring programmes.

Neonatal Sepsis-Newer Insights.

Sepsis is one of the leading causes of mortality and morbidity among neonates worldwide and especially affects the preterm neonates in resource-restricted settings. The infection may be acquired in utero, from the mother's genital tract or postnatally from the community or hospital environment and personnel. Factors including the time of exposure, size of the inoculum, immunity in the host, and virulence of the infectious agent affect the severity and course of illness. Culture-independent diagnostics, sepsis prediction scores, antibiotic stewardship, and preventive strategies including hand hygiene are ongoing efforts for reducing the neonatal sepsis burden.

A comparative study of perceived burden in parent caregivers of adolescents with epilepsy in a resource-restricted setting: Investigating the explanatory factors of perceived burden

ObjectiveParent caregivers often play vital roles in the care of adolescents with epilepsy (AWE) in resource-restricted settings; however, little is known about the burden borne by these parents. This study investigated the burden perceived by parents of AWE and described the explanatory factors. MethodsAn equal number (n = 121) of age- and gender-matched parent caregivers of AWE (cases) and parents of adolescents with sickle cell disease (comparison group) were interviewed with the Parent Illness Intrusiveness Rating Scale to assess disruptions in their relationships and lifestyle. Parents of AWE were assessed for psychological distress with the 12-item General Health Questionnaire, and AWE were interviewed with the Hospital Depression-Anxiety Scale. ResultsThe majority of the cases and the comparison group were mothers (76%), with mean (SD) ages of 44.11 (SD = 6.92) versus 43.59 (SD = 6.39) years, respectively. The prevalence rate of psychological distress in cases was 38%, and depressive-anxiety symptom was prevalent in 39.7% of AWE. The level of perceived burden was significant in all parent caregivers, albeit higher in cases relative to the comparison group across multiple domains, including relationship/personal development, intimacy, instrumental and global. A high level of burden in parents of AWE was predicted by a poor family financial and material support to the adolescents, increased contact hours with adolescents, psychological distress in the parent caregivers, and anxiety-depressive symptoms in AWE after controlling for cofounders. ConclusionThe study findings underscore the need for psychosocial support to bolster resilience and adaptive coping styles in parents of AWE, particularly in resource-restricted settings. A culturally sensitive interdisciplinary blueprint of locally viable actions model for psychosocial support for parent caregivers of AWE is strongly suggested. Future studies are indicated to shed more light on the modifiable risks of perceived burden, and the effectiveness of psychosocial interventions in parents of AWE.

Clinical and Laboratory Markers of Brain Abscess in Tetralogy of Fallot ('BA-TOF' Score): Results of a Case-Control Study and Implications for Community Surveillance.

Background Cardiogenic brain abscess (CBA) is the commonest noncardiac cause of morbidity and mortality in cyanotic heart disease (CHD). The clinical diagnosis of a CBA is often delayed due to its nonspecific presentations and the scarce availability of computed tomography (CT) imaging in resource-restricted settings. We attempted to identify parameters that reliably point to the diagnosis of a CBA in patients with Tetralogy of Fallot (TOF). Methods From among 150 children with TOF treated at a tertiary care institute over a 15-year period from 2001 to 2016, 30 consecutive patients with CBAs and 85 age- and sex-matched controls without CBAs were included in this retrospective case–control study. Demographic and clinical features, laboratory investigations, and baseline echocardiographic findings were analyzed for possible correlations with the presence of a CBA. Statistical Analysis Variables demonstrating significant bivariate correlations with the presence of a CBA were further analyzed using multivariate logistic regression (LR) analysis. Various LR models were tested for their predictive value, and the best model was then validated on a hold-out dataset of 25 patients. Results Among the 26 variables tested for bivariate associations with the presence of a CBA, some of the clinical, echocardiographic, and laboratory variables demonstrated significant correlations ( p < 0.05). LR analysis revealed elevated neutrophil–lymphocyte ratio and erythrocyte sedimentation rate values and a lower age-adjusted resting heart rate percentile to be the strongest independent biomarkers of a CBA. The LR model was statistically significant, (χ 2 = 23.72, p = <0.001), and it fitted the data well. It explained 53% (Nagelkerke R 2 ) of the variance in occurrence of a CBA, and correctly classified 83.93% of cases. The model demonstrated a good predictive value (area under the curve: 0.80) on validation analysis. Conclusions This study has identified simple clinical and laboratory parameters that can serve as reliable pointers of a CBA in patients with TOF. A scoring model—the ‘BA-TOF’ score—that predicts the occurrence of a CBA has been proposed. Patients with higher scores on the proposed model should be referred urgently for a CT confirmation of the diagnosis. Usage of such a diagnostic aid in resource-limited settings can optimize the pickup rates of a CBA and potentially improve outcomes.

Psychological distress and sleep problems in healthcare workers in a developing context during COVID-19 pandemic: Implications for workplace wellbeing

BackgroundEmotional wellbeing of healthcare workers is critical to the quality of patient care, and effective function of health services. The corona virus disease-2019 (COVID-19) pandemic exerted unique physical and emotional demands on healthcare workers, however little is known about the emotional wellbeing of healthcare workers during the COVID-19 pandemic in resource-restricted settings. This study investigated the prevalence of psychological distress, and sleep problems in healthcare workers in a COVID-19 referral hospital in Nigeria. MethodsA total of 303 healthcare workers were interviewed with the 12-item General Health Questionnaire (GHQ-12) to evaluate psychological distress, and the Pittsburgh Sleep Quality Index (PSQI) to assess multidimensional aspects of sleep, including quality, latency, duration, habitual efficiency, disturbances, use of sleeping medications and daytime dysfunction. ResultsThe participants were mostly males, 183(60.4%) and mean age was 38.8(SD = 8.9) years. Most of the participants were married (70.3%), had spent less than 10 years in service (72.9%), and had no medical comorbidity (92.1%). The prevalence of psychological distress was 23.4%, and six in every ten participants reported sleep problems. The largest proportion of participants reported difficulty in sleep latency (81.5%), duration (71.3%), and daytime dysfunction (69.6%), while approximately one third (32%) each reported using sleep medication, and had difficulty with sleep quality. Psychological distress was inter-related with poor sleep problems (p = 0.001; effect size = 0.2). ConclusionThe prevalence rates of psychological distress and sleep problems during the COVID-19 pandemic were several folds the rates previously reported in similar contexts. Preventative psychosocial support services for healthcare workers are indicated. The creation of a culturally-sensitive interdisciplinary blueprint for locally-viable actions model are strongly suggested ahead of future emergency situations.

Pragmatic Recommendations for the Use of Diagnostic Testing and Prognostic Models in Hospitalized Patients with Severe COVID-19 in Low- and Middle-Income Countries

ABSTRACTManagement of patients with severe or critical COVID-19 is mainly modeled after care of patients with severe pneumonia or acute respiratory distress syndrome from other causes. These models are based on evidence that primarily originates from investigations in high-income countries, but it may be impractical to apply these recommendations to resource-restricted settings in low- and middle-income countries (LMICs). We report on a set of pragmatic recommendations for microbiology and laboratory testing, imaging, and the use of diagnostic and prognostic models in patients with severe COVID-19 in LMICs. For diagnostic testing, where reverse transcription–PCR (RT-PCR) testing is available and affordable, we recommend using RT-PCR of the upper or lower respiratory specimens and suggest using lower respiratory samples for patients suspected of having COVID-19 but have negative RT-PCR results for upper respiratory tract samples. We recommend that a positive RT-PCR from any anatomical source be considered confirmatory for SARS-CoV-2 infection, but, because false-negative testing can occur, recommend that a negative RT-PCR does not definitively rule out active infection if the patient has high suspicion for COVID-19. We suggest against using serologic assays for the detection of active or past SARS-CoV-2 infection, until there is better evidence for its usefulness. Where available, we recommend the use of point-of-care antigen-detecting rapid diagnostic testing for SARS-CoV-2 infection as an alternative to RT-PCR, only if strict quality control measures are guaranteed. For laboratory testing, we recommend a baseline white blood cell differential platelet count and hemoglobin, creatinine, and liver function tests and suggest a baseline C-reactive protein, lactate dehydrogenase, troponin, prothrombin time (or other coagulation test), and D-dimer, where such testing capabilities are available. For imaging, where availability of standard thoracic imaging is limited, we suggest using lung ultrasound to identify patients with possible COVID-19, but recommend against its use to exclude COVID-19. We suggest using lung ultrasound in combination with clinical parameters to monitor progress of the disease and responses to therapy in COVID-19 patients. We currently suggest against using diagnostic and prognostic models as these models require extensive laboratory testing and imaging, which often are limited in LMICs.

Pragmatic Recommendations for the Management of Acute Respiratory Failure and Mechanical Ventilation in Patients with COVID-19 in Low- and Middle-Income Countries.

ABSTRACTManagement of patients with severe or critical COVID-19 is mainly modeled after care for patients with severe pneumonia or acute respiratory distress syndrome (ARDS) from other causes, and these recommendations are based on evidence that often originates from investigations in resource-rich intensive care units located in high-income countries. Often, it is impractical to apply these recommendations to resource-restricted settings, particularly in low- and middle-income countries (LMICs). We report on a set of pragmatic recommendations for acute respiratory failure and mechanical ventilation management in patients with severe/critical COVID-19 in LMICs. We suggest starting supplementary oxygen when SpO2 is persistently lower than 94%. We recommend supplemental oxygen to keep SpO2 at 88–95% and suggest higher targets in settings where continuous pulse oximetry is not available but intermittent pulse oximetry is. We suggest a trial of awake prone positioning in patients who remain hypoxemic; however, this requires close monitoring, and clear failure and escalation criteria. In places with an adequate number and trained staff, the strategy seems safe. We recommend to intubate based on signs of respiratory distress more than on refractory hypoxemia alone, and we recommend close monitoring for respiratory worsening and early intubation if worsening occurs. We recommend low–tidal volume ventilation combined with FiO2 and positive end-expiratory pressure (PEEP) management based on a high FiO2/low PEEP table. We recommend against using routine recruitment maneuvers, unless as a rescue therapy in refractory hypoxemia, and we recommend using prone positioning for 12–16 hours in case of refractory hypoxemia (PaO2/FiO2 < 150 mmHg, FiO2 ≥ 0.6 and PEEP ≥ 10 cmH2O) in intubated patients as standard in ARDS patients. We also recommend against sharing one ventilator for multiple patients. We recommend daily assessments for readiness for weaning by a low-level pressure support and recommend against using a T-piece trial because of aerosolization risk.

Pragmatic Recommendations for the Prevention and Treatment of Acute Kidney Injury in Patients with COVID-19 in Low- and Middle-Income Countries.

.Current recommendations for the management of patients with COVID-19 and acute kidney injury (AKI) are largely based on evidence from resource-rich settings, mostly located in high-income countries. It is often unpractical to apply these recommendations to resource-restricted settings. We report on a set of pragmatic recommendations for the prevention, diagnosis, and management of patients with COVID-19 and AKI in low- and middle-income countries (LMICs). For the prevention of AKI among patients with COVID-19 in LMICs, we recommend using isotonic crystalloid solutions for expansion of intravascular volume, avoiding nephrotoxic medications, and using a conservative fluid management strategy in patients with respiratory failure. For the diagnosis of AKI, we suggest that any patient with COVID-19 presenting with an elevated serum creatinine level without available historical values be considered as having AKI. If serum creatinine testing is not available, we suggest that patients with proteinuria should be considered to have possible AKI. We suggest expansion of the use of point-of-care serum creatinine and salivary urea nitrogen testing in community health settings, as funding and availability allow. For the management of patients with AKI and COVID-19 in LMICS, we recommend judicious use of intravenous fluid resuscitation. For patients requiring dialysis who do not have acute respiratory distress syndrome (ARDS), we suggest using peritoneal dialysis (PD) as first choice, where available and feasible. For patients requiring dialysis who do have ARDS, we suggest using hemodialysis, where available and feasible, to optimize fluid removal. We suggest using locally produced PD solutions when commercially produced solutions are unavailable or unaffordable.

Mitigating the risk of alcohol use among university students: Examining the feasibility and effects of screening and brief intervention - A quasi-experimental study

Background: The rising prevalence of alcohol use among youths in low resource settings is a major public health issue of concern, especially as alcohol use remains a leading contributor to deaths and disability globally. This study aimed to evaluate the effects of screening and brief intervention (SBI) on alcohol use risk among university students. Methods: In this quasi-experimental study, a total of 636 students were screened for alcohol use risk with the World Health Organization Alcohol, Smoking, and Substance Involvement Screening Test (WHO-ASSIST) version 3.1. All participants with moderate and high risk of alcohol use were administered brief intervention (BI) delivered by trained students at baseline, 1 month, and 3 months, with a final assessment in 6 months. Longitudinal data on their alcohol use risk were analyzed. Results: The mean age (standard deviation) of the participants was 21.13 (3.05) years and 44.5% were female. The prevalence of the current alcohol use based on the WHO-ASSIST was 49.2% (n = 315). Following three sessions of BI, the repeated measures ANOVA indicated that the WHO-ASSIST mean score for high-risk alcohol users (n = 44) fell from 33.23 (3.82) at baseline to 18.3 (9.84) at 6th month. This difference was statistically significant. Similarly, the mean score for moderate alcohol users fell from 19.62 (2.97) at baseline to 11.31 (5.52) at 6 months. The difference was statistically significant. There were significant group-level differences in the risk score over the study period, for the low risk, moderate risk, and high-risk users at the end of the study. Conclusion: Screening and BI showed significant benefits on alcohol use risk. Our findings suggest SBI as a feasible and effective intervention for mitigating the risk of alcohol use among young students in resource-restricted settings. Further research using a robust sample to reflect differences in setting and student characteristics is warranted.

Availability, Accessibility, and Quality of Conservative Kidney Management Worldwide.

People with kidney failure typically receive KRT in the form of dialysis or transplantation. However, studies have suggested that not all patients with kidney failure are best suited for KRT. Additionally, KRT is costly and not always accessible in resource-restricted settings. Conservative kidney management is an alternate kidney failure therapy that focuses on symptom management, psychologic health, spiritual care, and family and social support. Despite the importance of conservative kidney management in kidney failure care, several barriers exist that affect its uptake and quality. The Global Kidney Health Atlas is an ongoing initiative of the International Society of Nephrology that aims to monitor and evaluate the status of global kidney care worldwide. This study reports on findings from the 2018 Global Kidney Health Atlas survey, specifically addressing the availability, accessibility, and quality of conservative kidney management. Respondents from 160 countries completed the survey, and 154 answered questions pertaining to conservative kidney management. Of these, 124 (81%) stated that conservative kidney management was available. Accessibility was low worldwide, particularly in low-income countries. Less than half of countries utilized multidisciplinary teams (46%); utilized shared decision making (32%); or provided psychologic, cultural, or spiritual support (36%). One-quarter provided relevant health care providers with training on conservative kidney management delivery. Overall, conservative kidney management is available in most countries; however, it is not optimally accessible or of the highest quality.

Global Pathology Training in Residency and Fellowship: A Mutually Beneficial Intervention.

Most cancers occur in lower and middle income countries, where pathologists are scarce. Despite this, few pathology training programs offer global health electives, and trainees are not exposed to challenges associated with practicing in resource-restricted settings. To implement a global health elective model aimed at exposing trainees to global health while alleviating overburdened pathologists in resource-restricted settings. For 1 year, trainees at 2 US institutions reviewed cases shipped weekly from a pathology lab serving Trinidad and Tobago and Guyana. Turnaround time, specimen type, and trainee and clinician satisfaction were assessed. Trainees reviewed an average of 16 cases per week. Average turnaround time was 6 days. There was no significant difference between the turnaround time for the US trainees and the pathologist based in the lab in Trinidad. Trainees and clinicians reported a high level of satisfaction, and the collaboration was fruitful, resulting in the publication of a case report. We demonstrate that collaboration between US trainees and laboratories in resource-restricted settings, in the form of a global health elective, is mutually beneficial.

Utility of Low Dose Vasopressin for Persistent Pulmonary Hypertension of Newborn with Catecholamine Refractory Shock.

To evaluate the effect of low dose vasopressin on the hemodynamics of neonates with persistent pulmonary hypertension and catecholamine refractory shock. This retrospective study was conducted in a level III NICU of a tertiary care teaching hospital, south India. Eighteen neonates with hypoxemic respiratory failure due to persistent pulmonary hypertension of newborn with catecholamine refractory shock were studied. Neonates were managed for hypotension with conventional inotropic support with the additional use of low dose vasopressin (LDV). Effect of vasopressin on oxygenation index (OI), blood pressure, duration of inotropic usage and survival was evaluated. Mean OI was 38.2 ± 4.9, and mean blood pressure was 30.7 ± 5.3mmHg before the start of vasopressin. Initiation of LDV (0.0003 ± 0.0001IU/kg/min) for a median duration 36.4 ± 17.9h was followed by a reduction in OI (p < 0.001), control of hypotension (p < 0.001), reduction in lactic acidosis (p < 0.001) and decline in inotropic support. In resource-restricted settings, LDV may be useful as a rescue therapy for persistent pulmonary hypertension of newborn with catecholamine refractory shock.

Effectiveness of community health workers in improving early initiation and exclusive breastfeeding rates in a low-resource setting: A cluster-randomized longitudinal study.

Little evidence exists in Kenya on the potential of community health workers (CHWs) in promoting exclusive breastfeeding (EBF) and early breastfeeding initiation (EBI) in resource‐restricted settings where very low EBF rates (2% to 12%) have been documented. The study utilized CHWs and assessed their effectiveness in promoting EBF and EBI. The cluster‐randomized longitudinal design was used and sixteen villages from Kiandutu Slum in Thika randomly assigned into either intervention group (IG) or comparison group (CG). Pregnant women attending Maternal Child Health (MCH) clinic were recruited. The IG received nutrition education sessions conducted by CHWs at home, two prenatally and six postnatally, plus the routine MCH care. The CG went through routine MCH care only. Infants feeding data were collected at 6, 10, 14, and 24 weeks postpartum by research assistants blinded to the intervention allocation. Differences in EBF and EBI in the two groups were tested using χ 2 tests, Kaplan–Meier survival analysis and generalized estimating equations. Of the 526 recruited in the study, 431 remained and were included in the analysis (IG = 176) and CG (225). The prevalence of EBF at 24 weeks was 45.3% in the IG compared with 15.0% in the CG, revealing a statistically significant difference log rank = 20.277, (1, n = 314) p < .001. The difference was not statistically significant in EBI prevalence between the IG (58.2%) and CG (60.3%; χ 2 = 0.008, p = .928). The CHWs have potential effectiveness in promoting EBF but not EBI. The link between the health center and CHWs should be strengthened to promote EBF.
