Rapid, Portable, and Electricity-free Sample Extraction Method for Enhanced Molecular Diagnostics in Resource-Limited Settings.

The COVID-19 pandemic has highlighted the need for rapid and reliable diagnostics that are accessible in resource-limited settings. To address this pressing issue, we have developed a rapid, portable, and electricity-free method for extracting nucleic acids from respiratory swabs (i.e. nasal, nasopharyngeal and buccal swabs), successfully demonstrating its effectiveness for the detection of SARS-CoV-2 in residual clinical specimens. Unlike traditional approaches, our solution eliminates the need for micropipettes or electrical equipment, making it user-friendly and requiring little to no training. Our method builds upon the principles of magnetic bead extraction and revolves around a low-cost plastic magnetic lid, called SmartLid, in combination with a simple disposable kit containing all required reagents conveniently prealiquoted. Here, we clinically validated the SmartLid sample preparation method in comparison to the gold standard QIAamp Viral RNA Mini Kit from QIAGEN, using 406 clinical isolates, including 161 SARS-CoV-2 positives, using the SARS-CoV-2 RT-qPCR assays developed by the US Centers for Disease Control and Prevention (CDC). The SmartLid method showed an overall sensitivity of 95.03% (95% CI: 90.44-97.83%) and a specificity of 99.59% (95% CI: 97.76-99.99%), with a positive agreement of 97.79% (95% CI: 95.84-98.98%) when compared to QIAGEN's column-based extraction method. There are clear benefits to using the SmartLid sample preparation kit: it enables swift extraction of viral nucleic acids, taking less than 5 min, without sacrificing significant accuracy when compared to more expensive and time-consuming alternatives currently available on the market. Moreover, its simplicity makes it particularly well-suited for the point-of-care where rapid results and portability are crucial. By providing an efficient and accessible means of nucleic acid extraction, our approach aims to introduce a step-change in diagnostic capabilities for resource-limited settings.

Detection of drug-resistant malaria in resource-limited settings: efficient and high-throughput surveillance of artemisinin and partner drug resistance.

OBJECTIVES: Artemisinin-resistant Plasmodium falciparum malaria is currently spreading globally, including in Africa. Artemisinin resistance also leads to resistance to partner drugs used in artemisinin-based combination therapies. Sequencing of kelch13, which is associated with artemisinin resistance, culture-based partner drug susceptibility tests, and ELISA-based growth measurement are conventionally used to monitor resistance; however, their application is challenging in resource-limited settings. METHODS: An experimental package for field studies with minimum human/material requirements was developed. RESULTS: First, qPCR-based SNP assay was applied in artemisinin resistance screening, which can detect mutations within 1 h and facilitate sample selection for subsequent processes. It had 100% sensitivity and specificity compared with DNA sequencing in the detection of the two common artemisinin resistance mutations in Uganda, C469Y and A675V. Moreover, in the partner drug susceptibility test, the cultured samples were dry-preserved on a 96-well filter paper plate and shipped to the central laboratory. Parasite growth was measured by ELISA using redissolved samples. It well reproduced the results of direct ELISA, reducing significant workload in the field (Pearson correlation coefficient: 0.984; 95% CI: 0.975-0.990). CONCLUSIONS: Large-scale and sustainable monitoring is required urgently to track rapidly spreading drug-resistant malaria. In malaria-endemic areas, where research resources are often limited, simplicity and feasibility of the procedure is especially important. Our approach combines a qPCR-based rapid test, which is also applicable to point-of-care diagnosis of artemisinin resistance and centralized analysis of ex vivo culture. The approach could improve efficiency of field experiments and accelerate global drug resistance surveillance.

The management of osteosarcoma in children and adolescents in a resource-limited setting: quality improvement considerations to improve treatment outcomes.

BACKGROUND: The survival rates for children and adolescents with osteosarcoma in low-income countries are poor. Insufficient data regarding the challenges of managing osteosarcoma in resource-limited settings has been published. We evaluated the treatment of osteosarcoma in children and adolescents with the aim of improving the health system and management outcomes. METHODS: We sourced data on children under 18 years treated for osteosarcoma at the Uganda Cancer Institute between January 2016 and December 2020. Descriptive statistics and Kaplan-Meier survival analysis were used. RESULTS: Seventy-four osteosarcoma cases were identified, with a median age of 13 years (IQR 9.8-15). Referrals were made after a median of 28 days (range 1-147). Before appropriate referral, more than a quarter (26%) had undergone invasive procedures that could compromise tumour integrity and outcome. Half (50%) of the patients had metastatic disease at diagnosis, primarily to the lungs (n = 43; 92%). Only 14 (33%) patients received neoadjuvant chemotherapy. Forty-three (58.1%) patients underwent limb amputation surgery, including 25 localized tumours and 18 patients with distant metastatic disease. No metastatectomies were performed. Adjuvant chemotherapy was delayed for longer than 21 days in 26 (61%) patients. No pathology reports described the status of resection margins or the degree of chemotherapy-induced necrosis. Twenty-six (35%) patients abandoned treatment, mainly due to pending radical surgery (n = 18/26; 69%). Only 18% (n = 13) were still alive; 46% (n = 34) had died; and 37% (n = 27) had an unknown status. The median overall survival was 1.1 years, and was significantly negatively affected by disease metastasis, timing of adjuvant therapy, and treatment abandonment. CONCLUSIONS: Osteosarcoma outcomes for children and adolescents at the Uganda Cancer Institute are extremely poor. The quality of care can be improved by addressing delayed referrals, high rates of prior manipulative therapy, metastatic disease, treatment abandonment, surgical challenges, and delayed resumption of adjuvant chemotherapy.

Genetic Epidemiology and Clinical Characteristics of Patients with Spinocerebellar Ataxias in an Unexplored Brazilian State, Using Strategies for Resource-Limited Settings.

Spinocerebellar ataxias (SCAs) have a worldwide average prevalence of 2.7 cases per 100,000 individuals, with significant geographic variability. This study aimed to develop resource-limited strategies to detect and characterize the frequency and genetic-clinical profile of SCAs in an unexplored population from Alagoas State, a low Human Development Index state in northeastern Brazil. Active search strategies were employed to identify individuals with a diagnosis or clinical suspicion of SCAs, and a protocol for clinical and molecular evaluation was applied in collaboration with a reference center in Neurogenetics. A total of 73 individuals with SCAs were identified, with a minimum estimated prevalence of 2.17 cases per 100,000 inhabitants. SCA3 was the most common type (75.3%), followed by SCA7 (15.1%), SCA1 (6.8%), and SCA2 (2.7%). Patients with SCA3 subphenotype 2 were the most predominant. Detailed analysis of patients with SCA3 and SCA7 revealed age at onset and clinical features congruent with other studies, with gait disturbance and reduced visual capacity in SCA7 as the main initial manifestations. The study also identified many asymptomatic individuals at risk of developing SCAs. These findings demonstrate that simple and collaborative strategies can enhance the detection capacity of rare diseases such as SCAs in resource-limited settings and that Alagoas State has a minimum estimated prevalence of SCAs similar to the world average.

Building Equitable Neuroscience Research Collaborations in Resource-limited Settings.

The burden of noncommunicable neurological disorders, such as stroke, dementia, and headache disorders, are on the rise in low- to middle-income countries (LMICs), while neuroinfectious diseases remain a major concern. The development of neuroscience research aimed at defining the burden of neurological diseases across the lifespan, as well as optimizing diagnosis and treatment strategies, is fundamental to improving neurological health in resource-limited settings. One of the key factors to advancing neuroscience research in LMICs is the establishment of effective collaborations based on responsible and trustworthy partnerships between local scientists in LMICs and international collaborators. LMIC researchers face many logistical, institutional, and individual level challenges as they embark on their neuroscience research journey. Despite these challenges, there are opportunities for improving LMIC investigator-led research that should focus on human and institutional infrastructure development. With regard to human capacity building, potential areas for offering support include enhancing research methodology training, offering instruction in manuscript and grant-writing, institutionalizing mentorship programs, and providing opportunities to conduct funded, mentored research to disseminate in high-impact journals. The foundational elements required for implementing and optimizing neuroscience research within an institution include an institutional review board, mentorship programs, data management, research administration, and laboratory facilities. This institutional capacity varies significantly across and within countries, and many rely on collaborations with better-resourced institutions to initiate research. Successful equitable collaborations ensure the engagement of all local and international stakeholders, as well as implementation of a self-sustaining long-term program. Building research capacity in LMICs is an essential endeavor that requires ongoing commitment to training independent scientists. As research capacity increases, LMIC institutions and governments should consider developing competitive research grant programs to support innovative studies led by local researchers, foster regional collaborations, and hence create a sustainable and independent neuroscience research environment.

Developing Systems of Emergency and Inpatient Neurologic Care in Resource-Limited Settings.

Neurologic diseases represent a significant global health challenge, leading to disability and mortality worldwide. Healthcare systems in low- and middle-income countries are disproportionally affected. In these resource-limited settings, numerous barriers hinder the effective delivery of emergency and inpatient neurologic care, including shortages of trained personnel, limited access to diagnostics and essential medications, inadequate facilities, and absence of rehabilitation services. Disparities in the neurology workforce, limited access to neuroimaging, and availability of acute interventions further exacerbate the problem. This article explores strategies to enhance global capacity for inpatient neurologic care, emphasizing the importance of workforce development, context-specific protocols, telehealth solutions, advocacy efforts, and collaborations.

Developing Systems of Care for Stroke in Resource-limited Settings.

Although stroke prevention and treatment strategies have significantly advanced in recent years, implementation of these care elements in resource-limited settings can be challenging, since the burden of stroke is higher and access to stroke care is lower. Barriers to stroke care in resource-limited settings include insufficient prevention, reduced awareness of stroke symptoms, limited prehospital care and lack of triage systems, limited access to comprehensive stroke centers, inadequate personnel education, lack of staff and resources, as well as limited access to neuroimaging, thrombolytics, mechanical thrombectomy, neurosurgical care, and rehabilitation. Here, we suggest strategies to improve stroke care in these settings, including public health campaigns, protocols for prehospital notification, organized flow to specialized stroke centers, development of dedicated stroke units, and utilization of telemedicine and telerehabilitation. We also highlight the role of international organizations and governments in reducing the global burden of stroke.

Switching Vancomycin Monitoring From Trough Concentration to Area Under the Curve Estimation by Bayesian Forecasting: A Short Communication on a Cost-Benefit Study in Resource-Limited Settings.

BACKGROUND: This study was conducted to evaluate the cost-benefit indicators of a vancomycin monitoring protocol based on area under the curve estimation using commercial Bayesian software. METHODS: This quasi-experimental study included patients who were aged >18 years with a vancomycin prescription for >24 hours. Patients who were terminally ill or those with acute kidney injury (AKI) ≤24 hours were excluded. During the preintervention period, doses were adjusted based on the trough concentration target of 15-20 mg/L, whereas the postintervention period target was 400-500 mg × h/L for the area under the curve. The medical team was responsible for deciding to stop the antimicrobial prescription without influence from the therapeutic drug monitoring team. The main outcomes were the incidence of AKI and length of stay. Cost-benefit simulation was performed after statistical analysis. RESULTS: There were 96 patients in the preintervention group and 110 in the postintervention group. The AKI rate decreased from 20% (n = 19) to 6% (n = 6; P = 0.003), whereas the number of vancomycin serum samples decreased from 5 (interquartile range: 2-7) to 2 (interquartile range: 1-3) examinations per patient ( P < 0.001). The mean length of hospital stay for patients was 26.19 days after vancomycin prescription, compared with 17.13 days for those without AKI ( P = 0.003). At our institution, the decrease in AKI rate and reduced length of stay boosted yearly savings of up to US$ 369,000 for 300 patients receiving vancomycin therapy. CONCLUSIONS: Even in resource-limited settings, a commercial Bayesian forecasting-based protocol for vancomycin is important for determining cost-benefit outcomes.

Diagnosing and Treating Blastic Plasmacytoid Dendritic Cell Neoplasm in a Resource-Limited Setting.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematological malignancy with limited treatment options and poor prognosis. This case report presents the clinical course and management of a 62-year-old man with BPDCN in a resource-limited setting. The patient presented with constitutional symptoms and abnormal complete blood count findings. Initial treatment was performed with an acute lymphoblastic leukemia-based chemotherapy regimen, and the patient achieved complete remission, but the disease recurred 7 months after the initial diagnosis was confirmed in April 2022. The subsequent therapy was not effective, and the patient died during treatment. This case highlights the challenges in managing BPDCN and the need for further research to improve outcomes.

Successful Application of a Hemoperfusion Machine in Separated System CRRT: Evaluating Effectiveness and Safety in Critically Ill Patients With AKI in Resource-Limited Settings.

BACKGROUND: It is imperative to note that integrated system continuous renal replacement therapy (CRRT) necessitates a sophisticated and costly apparatus, potentially limiting its availability within resource-limited settings. The introduction of a separated system for continuous veno-venous hemofiltration (CVVH), characterized by uncomplicated setup procedures with a hemoperfusion machine, holds promise as a feasible alternative to CRRT for critically ill patients with acute kidney injury (AKI). METHODS: We aimed to retrospectively analyze the effectiveness and safety of separated CRRT applied from a hemoperfusion machine in critically ill patients with AKI during the January 2015 to December 2021 period. We also examine the in-hospital mortality rate and multivariate logistic regression analysis to uncover the factors that affect mortality. RESULTS: We included a total of 129 critically ill patients who received separated system CRRT. The SOFA score at CRRT initiation was 12.6 ± 3.8. The fluid accumulation at the day of CRRT initiation was 3900 mL (622-8172 mL) All patients received pre- and postdilution CVVH. The mean prescribed CRRT dose was 22.4 ± 3.1 mL/kg/h. We found no serious complications including circuit explosion and air embolism. The in-hospital mortality rate was 68.9%. High SOFA score and positive fluid accumulation at CRRT initiation serve as predictors of survival. CONCLUSIONS: Separated system CRRT using a hemoperfusion machine provides a simplified system to operate and is proven to be effective and safe in real-life practice, especially in resource-limited areas.

Outcome of pediatric living donor liver transplant: Experience from Pakistan; a resource limited setting.

INTRODUCTION: Liver transplantation (LT) has emerged as a lifesaving modality for many liver diseases in children. Pediatric LT is an established treatment in the Western world but is relatively a new procedure in resource-limited countries like Pakistan. The study aims to highlight the outcomes and survival of pediatric recipients from the first pediatric liver transplant center in Pakistan. METHOD: A retrospective analysis of pediatric LT was done from 2012 to 2019. The study was conducted in the Hepatobiliary and liver transplant department of Shifa International Hospital (SIH), Islamabad. A detailed analysis for indications for pediatric LT, survival, and complications was done. RESULTS: Forty-five patients under 18 years of age underwent Living donor liver transplant (LDLT) in SIH. Median age was 9 years and M:F of 2:1. Cryptogenic liver disease followed by Wilson disease were the two most common indications of LT. The majority of patients had chronic liver disease 34 (75%) while 11 (24%) had acute liver failure. The right lobe graft was the most common type of graft 19 (42.2%). Thirty days, 1-year, 3-year, and 5-year survival was 77.8%, 75.6%, 73.3%, and 60.6% respectively. Mortality was highest in patients with biliary atresia 4 (33%). Causes of death included pulmonary embolism, sepsis, surgical complications, and acute kidney injury. Mean survival was 88.850 months (±7.899) (CI 73.369-104.331). CONCLUSION: Pediatric LDLT has offered disease-free survival for patients. Survival can improve further with nutritional rehabilitation and anticipation and management of post-operative complications.

ESPGHAN recommendations on treatment of chronic hepatitis C virus infection in adolescents and children including those living in resource-limited settings.

Hepatitis C virus (HCV) infection is a major cause of chronic liver disease worldwide, with more than three million viraemic adolescents and children. Treatment of adults with HCV infection and HCV-related liver disease has advanced considerably thanks to development and improvements in therapy. Direct-acting antiviral regimens are safe and effective. Three regimens with pangenotypic activity (glecaprevir/pibrentasvir, sofosbuvir/velpatasvir and sofosbuvir/velpatasvir/voxilaprevir) and three regimens with genotype-specific activity (sofosbuvir/ribavirin, sofosbuvir/ledipasvir and elbasvir/grazoprevir) have been approved with age-specific limitation for treatment of children with chronic hepatitis C by the European Medicines Agency and the United States Food and Drug Administration. The World Health Organization has set the ambitious target to eliminate hepatitis C as a major public health threat by 2030 and based its actions against HCV on the large use of direct acting antivirals. These updated European Society for Pediatric Gastroenterology, Hepatology and Nutrition recommendations on treatment of hepatitis C describe the optimal therapeutic management of adolescents and children with HCV infection including specific indications for those living in resource-limited settings.

Age and healthy lifestyle behavior's disparities and similarities on knowledge of myocardial infarction symptoms and risk factors among public and outpatients in a resource-limited setting, cross-sectional study in greater Gaborone, Botswana.

OBJECTIVES: In this cross-sectional study from Botswana, we investigated knowledge of myocardial infarction (MI) symptoms and risk factors among the general public and outpatients with MI risk factors based on age and lifestyle behaviors, in addition to assessing associations with sociodemographic and MI risk factors. METHOD: Open-ended questionnaires about 8 MI symptoms and 10 risk factors, were administered by research assistants to a representative selection of outpatients (n = 525) and the public (n = 2248). Weight and height were measured in all participants and BMI was calculated. Knowledge scores were compared between the two groups. We examined whether sociodemographic and MI risk factors had impact on the scores. Analyses were further adjusted for lifestyle behavior (smoking status, dietary status and physical activities). RESULTS: The valid response rate was 97.9% comprising 97.8% for the public (n = 2199) and 98.1% for outpatients (n = 515). Public respondents (35.2 ± 12.3 years) were younger than outpatients (38.5 ± 12.6 years). The public comprised 56.9% females while outpatients 54.6%. In general, outpatients had higher knowledge of MI symptoms than the public, with mean scores ± SD of 3.49 ± 2.84 vs 2.80 ± 2.54. Outpatients also had higher knowledge score of MI risk factors than the public, with mean scores, 5.33 ± 3.22 vs 3.82 ± 3.07. For MI symptoms, outpatients were more aware than the public for chest pains among all ages, for arm pain/ numbness, neck/ jaw pain radiating to/ from chest, and feeling sick or looking pallor on the skin among those aged 35-49 years. Among both the public and outpatients, lower knowledge of both MI symptoms and risk factors was associated with primary education, not residing/working together, history of hypertension, no history of heart disease/stroke, and obesity. There were similarities and disparities on MI knowledge among respondents with various numbers of healthy lifestyle behaviours. CONCLUSION: Results call for urgent educational campaigns on awareness and knowledge of MI and using strategies based on age and lifestyle behavior.

Predictors of complications and mortality among patients undergoing pacemaker implantation in resource-limited settings: a 10-year retrospective follow-up study.

INTRODUCTION: Pacemakers (PMs) are used to treat patients with severe bradycardia symptoms. They do, however, pose several complications. Even with these risks, there are only a few studies assessing PM implantation outcomes in resource-limited settings like Ethiopia and other sub-Saharan countries in general. Therefore, this study aims to assess the mid-term outcome of PM implantation in patients who have undergone PM implantation in the Cardiac Center of Ethiopia by identifying the rate and predictors of complications and death. METHODOLOGY: This retrospective study was conducted at the Cardiac Center of Ethiopia from October 2023 to January 2024 on patients who had PM implantation from September 2012 to August 2023 to assess the midterm outcome of the patients. Complication rate and all-cause mortality rate were the outcomes of our study. Multivariable logistic regression was used to identify factors associated with complications and death. To analyze survival times, a Kaplan-Meier analysis was performed. RESULTS: This retrospective follow-up study included 182 patients who underwent PM implantation between September 2012 and August 2023 and were at least 18 years old. The patients' median follow-up duration was 72 months (Interquartile range (IQR): 36-96 months). At the end of the study, 26.4% of patients experienced complications. The three most frequent complications were lead dislodgement, which affected 6.6% of patients, PM-induced tachycardia, which affected 5.5% of patients, and early battery depletion, which affected 5.5% of patients. Older age (Adjusted Odds Ratio (AOR) 1.1, 95% CI 1.04-1.1, p value < 0.001), being female (AOR 4.5, 95%CI 2-9.9, p value < 0.001), having dual chamber PM (AOR 2.95, 95%CI 1.14-7.6, p value = 0.006) were predictors of complications. Thirty-one (17%) patients died during the follow-up period. The survival rates of our patients at 3, 5, and 10 years were 94.4%, 92.1%, and 65.5% respectively with a median survival time of 11 years. Patients with a higher Charlson comorbidity index before PM implantation (AOR 1.2, 95% CI 1.1-1.8, p = 0.04), presence of complications (AOR 3.5, 95% CI 1.2-10.6, p < 0.03), and New York Heart Association (NYHA) class III or IV (AOR 3.3, 95% CI 1.05-10.1, p = 0.04) were associated with mortality. CONCLUSION: Many complications were experienced by patients who had PMs implanted, and several factors affected their prognosis. Thus, it is essential to identify predictors of both complications and mortality to prioritize and address the manageable factors associated with both mortality and complications.

Intravenous cyclophosphamide therapy in children with calcineurin inhibitor-resistant steroid-resistant nephrotic syndrome in a resource-limited setting.

BACKGROUND: In pediatric steroid-resistant nephrotic syndrome (SRNS), calcineurin inhibitors (CNIs) are recommended as first-line therapy, with efficacy ranging between 60 and 80%, implying a substantial proportion will exhibit CNI resistance. Which alternate immunosuppressive therapy should be used in non-genetic pediatric SRNS exhibiting CNI resistance is especially relevant in low- to middle-income countries (LMIC), where the prohibitive costs of certain drugs such as monoclonal antibodies often determine therapy choice. METHODS: The primary objective was to assess the efficacy of intravenous cyclophosphamide in a proportion of children aged 1-18 years with CNI-resistant SRNS with a complete response (CR) or partial response (PR) at 6 months from commencement of pulse therapy. The secondary objectives were to assess the proportion and profile of infections and adverse effects. RESULTS: Of 90 children with idiopathic SRNS presenting between January 2013 and December 2022, 29 (32.2%) had CNI resistance and were enrolled. They were administered monthly intravenous cyclophosphamide pulses (6 pulses). Median (IQR) duration of follow-up was 48 (29.5, 63.5) months. At the end of 6 months of cyclophosphamide therapy, 13 (44.8%) attained CR and 4 (13.8%) attained PR, with an overall cyclophosphamide success rate of 58.6%. The efficacy of intravenous cyclophosphamide was higher in secondary (9/10; 90%) versus primary CNI resistance (8/19; 42.1%) (p = 0.029). Three children (3/29; 10.3%) developed systemic infections within 12 months of initiation of cyclophosphamide therapy, similar to the rate of systemic infections among children receiving CNI for SRNS management (6/41; 14.6%) (p = 0.85). CONCLUSIONS: It is prudent to try intravenous cyclophosphamide in CNI-resistant SRNS in LMIC, given the reasonable cost and good efficacy rates (58.6%).

Catastrophic healthcare expenditure and caregiver burden in pediatric chronic kidney disease - a mixed methods study from a low resource setting.

BACKGROUND: Caregivers of children with chronic kidney disease (CKD) in low resource settings must provide complex medical care at home while being burdened by treatment costs often paid out-of-pocket. We hypothesize that caregiver burden in our low resource setting is greater than reported from high income countries and is associated with frequent catastrophic healthcare expenditure (CHE). METHODS: We conducted a mixed-methods study of primary caregivers of children with advanced CKD (stage 3b-5) in our private-sector referral hospital in a low resource setting. We assessed caregiver burden using the Pediatric Renal Caregiver Burden Scale (PRCBS) and measured financial burden by calculating the proportion of caregivers who experienced CHE (monthly out-of-pocket healthcare expenditure exceeding 10% of total household monthly expenditure). We performed a qualitative reflexive thematic analysis of caregiver interviews to explore sources of burden. RESULTS: Of the 45 caregivers included, 35 (78%) had children on maintenance dialysis (25 PD, 10 HD). Mean caregiver burden score was 141 (± 17), greater than previously reported. On comparative analysis, PRCBS scores were higher among caregivers of children with kidney failure (p = 0.005), recent hospitalization (p = 0.03), non-earning caregivers (p = 0.02), caring for > 2 dependents (p = 0.009), and with high medical expenditure (p = 0.006). CHE occurred in 43 (96%) caregivers of whom 37 (82%) paid out-of-pocket. The main themes derived relating to caregiver burden were severe financial burden, mental stress and isolation, and perpetual burden of concern. CONCLUSION: Parents of children with CKD experienced severe caregiver burden with frequent CHE and relentless financial stress indicating an imminent need for social support interventions.

Digitizing operating theater data in resource-limited settings: Understanding surgical care delivery post-implementation at Tanzanian referral hospital.

BACKGROUND: Digitizing surgical data infrastructure is critical for policymakers to make informed decisions. The implementation of the first web-based operating theater (OT) recordings at Muhimbili Orthopedic Institute (MOI) represents significant advancements in data management for Tanzania. This study aims to share post-platform implementation outcomes, challenges, and insights gained offering guidance to settings facing similar data repository challenges. METHODS: In July 2023, after training clinicians, the platform was deployed at MOI operating theaters (OTs) to facilitate prospective data entry following procedures, ensuring timely updates of perioperative outcomes. Semi-structured interviews were conducted with key stakeholders to gather insights into the platform's functionality and efficient data management systems. We presented data from August 2023 to February 2024 along with platform insights. RESULTS: Over 4449 procedures were conducted, comprising 1321 emergencies and 3128 electives, with orthopedics/trauma accounting for the majority (3606). Trauma-related emergencies (921) predominate among interventions. General anesthesia was prevalent; 60.56% in emergencies and 44.51% in electives. Orthopedics/trauma utilized 90.91% of assigned operating days in electives, while neurosurgery utilized 93.39% (p < 0.011). The cancellation rate was 7.5%, primarily due to emergency interferences (32%). Of procedures, 96.76% were discharged, while 2.81% died. Challenges encountered during platform implementation included securing local support, integrating technology, and navigating administrative adjustments. Lessons learned emphasized continuous communication for stakeholder buy-in and training for platform familiarity. CONCLUSION: The web-based OT recordings at MOI succeeded with local support and showed promise for wider scalability. To ensure sustainability, ongoing follow-up, monitoring of platform functionality, local funding establishment, and strengthening global partnerships are recommended.

BACKGROUND: Cervical cancer in pregnancy is a rare event. Diagnosis and management of cervical cancer in pregnancy is complicated and challenging in a low resource setting. CASE PRESENTATION: Herein, we present a case of cervical cancer (FIGO stage IB3) diagnosed at 28+ 5 weeks and successfully managed at 37+ 2 weeks of gestation in a 27-year-old woman. CONCLUSION: This is the first case report on cervical cancer in pregnancy from Bhutan. It highlights the diagnostic and management challenges in a low resource country.

Fracture Risk Assessment Tool-Based Screening for Osteoporosis in Older Adults in Resource-Limited Settings.

PURPOSE: Osteoporosis is a pressing public health concern among older adults, contributing to substantial mortality and morbidity rates. Low- to middle-income countries (LMICs) often grapple with limited access to dual-energy X-ray absorptiometry (DXA), the gold standard for early osteoporosis detection. This study aims to assess the performance of the FRAX® score as a population-wide screening tool for predicting osteoporosis risk, rather than fracture, in individuals aged 50 and above within an LMIC context. METHODS: This retrospective cohort study (n=864) assessed the performance of the FRAX® score for predicting osteoporosis risk using comparative c-statistics from Receiver Operating Characteristic (ROC) curves. Hazard ratios (HR) and 95 % confidence intervals (CI) were calculated, with p-values <0.05 indicating statistically significant. RESULTS: The 10-year FRAX® probability for hip fracture, calculated without bone mass density (BMD), exhibited significantly superior performance compared to the 10-year FRAX® probability for major fracture in predicting osteoporosis risk (AUROC: 0.71 versus 0.67, p<0.001). Within 2 to 10 years of follow-up, the 10-year FRAX® probability for hip fracture showed both greater predictive performance and net benefit in the decision curve compared to the FRAX® 10-year probability for major fracture. A newly established cutoff of 1.9 % yielded a negative predictive value of 92.9 % (95 %CI: 90.4-94.8 %) for the 10-year FRAX® probability for hip fracture. CONCLUSION: The 10-year FRAX® probability for hip fracture estimated without BMD emerges as an effective 10-year screening tool for identifying osteoporosis risk in aged 50 and older, especially when confronted with limited access to DXA scans in LMICs. MINI ABSTRACT: The Fracture Risk Assessment Tool score performance as an osteoporosis screening tool was assessed in areas with limited dual-energy X-ray access. The hip fracture probability showed better performance than major fracture probability within 2 to 10 years. The tool emerges as effective for screening osteoporosis risk in individuals over 50.

Usability of a smartphone-compatible, confocal micro-endoscope for cervical cancer screening in resource-limited settings.

BACKGROUND: More efficient methods to detect and treat precancerous lesions of the cervix at a single visit, such as low-cost confocal microscopy, could improve early diagnosis and hence outcomes. We piloted a prototype smartphone-compatible confocal micro-endoscope (SCME) among women presenting to a public cervical cancer screening clinic in Kampala, Uganda. We describe the piloting of the SCME device at an urban clinic used by lower cadre staff. METHODS: We screened women aged 18 and 60 years, who presented for cervical cancer screening at the Kawempe National Referral Hospital Kampala, and evaluated the experience of their providers (nurses). Nurses received a 2-day training by the study doctors on how to use the SCME, which was added to the standard Visual Inspection with Acetic acid (VIA)-based cervical cancer screening. The SCME was used to take colposcopy images before and after VIA at positions 12 and 6 O'clock if VIA negative, and on precancer-suspicious lesions if VIA positive. We used questionnaires to assess the women's experiences after screening, and the experience of the nurses who operated the SCME. RESULTS: Between November 2021 and July 2022, we screened 291 women with a median age of 36 years and 65.7% were HIV positive. Of the women screened, 146 were eligible for VIA, 123 were screened with the SCME, and we obtained confocal images from 103 women. Of those screened with the SCME, 60% found it comfortable and 81% were willing to screen again with it. Confocal images from 79% of the women showed distinguishable cellular features, while images from the remaining 21% were challenging to analyze. Nurses reported a mean score of 85% regarding the SCME's usefulness to their work, 71% regarding their satisfaction and willingness to use it again, 63% in terms of ease of use, and 57% concerning the ease of learning how to operate the SCME. CONCLUSION: Our findings demonstrate the feasibility of using the SCME by lower cadre staff in low-resource settings to aid diagnosis of precancerous lesions. However, more work is needed to make it easier for providers to learn how to operate the SCME and capture high-quality confocal images.
