Abstract Number ‐ 109: Mechanical Thrombectomy Hands‐on Skill Workshop for MT2020+ in the Caribbean

Introduction While mechanical thrombectomy (MT) is proven to be lifesaving and disability‐sparing, there remains disparities in access in low‐ to middle‐income countries (LTMICs), including the Caribbean. We hypothesized that team‐oriented MT workshops would improve MT skills and change practice patterns for MT services in this region. Methods We designed a 22‐hour MT workshop which was conducted as two identical events: in English (Jamaica, January 2022), and in Spanish (Dominican Republic, May 2022). The workshops included neurointerventional teams (practicing neurointerventionalists, neuroIR nurses and technicians), focused on patient selection, acutetreatment and post‐MT care of patients with stroke due to large vessel occlusion. MT skills, procedure duration and potential harmful techniques were recorded before and after by independent evaluators utilizing flow models under fluoroscopy. Overall course evaluation was performed. Press conferences were included to raise stroke awareness and emphasize the importance of early stroke presentation. Results Twenty‐two physicians and their teams from eight countries across the Caribbean completed the didactic and hands‐on training. Eighteen groups completed both pre‐ and post‐MT hands‐on testing and were included in the final analysis. Pre‐ and post‐course hands‐on assessment showed that the course effectively reduced the total time to complete a simulated MT procedure from 36.5 to 21.1 min (Figure 1; p< 1.0×10‐7). All groups showed an improvement in measures of good MT techniques, which resulted in a 39% improvement in complete reperfusion (8/18 groups achieved a TICI 3 score on pre‐course vs. 15/18 groups on post‐course). There was a significant reduction in total potentially dangerous maneuvers by 82% (p< 0.002), with 12/18 groups performing an average 2 dangerous maneuvers on pre‐course simulation vs. only 4/18 groups performing an average 1 dangerous maneuver after completing the course. Participants also demonstrated increased knowledge of stroke treatment and stroke system of care. Utilizing a basic stroke knowledge questionnaire, we found 28% respondents did not have a baseline passing grade vs 100% passed after the workshop. The average post‐workshop knowledge score was 80%. Universally the workshop was rated as very satisfactory and likely to change practice in 93% of the Dominican Republic participants and 75% among Jamaican participants. Conclusions A team‐based approach to MT training is novel, effective in reducing time to reperfusion and harmful techniques, and improves competencies. Team members independently demonstrated advanced stroke learning post‐training. To our knowledge, this is the first workshop of its kind; it is feasible, practice‐changing and creates a pathway for increasing access to MT in LTMICs.

Predictors of Survival in Patients with Metastatic Brain Tumors: Experience from a Low-to-Middle-Income Country.

Objective The interplay of static factors and their effect on metastatic brain tumor survival, especially in low-to-middle-income countries (LMICs), has been rarely studied. To audit our experience, and explore novel survival predictors, we performed a retrospective analysis of brain metastases (BM) patients at Shaukat Khanum Memorial Cancer Hospital (SKMCH), Pakistan. Materials and Methods A retrospective review was conducted of consecutive patients who presented with BM between September 2014 and September 2019 at SKMCH. Patients with incomplete records were excluded. Statistical Analysis SPSS (v.25 IBM, Armonk, New York, United States) was used to collect and analyze data via Cox-Regression and Kaplan-Meier curves. Results One-hundred patients (mean age 45.89 years) with confirmed BM were studied. Breast cancer was the commonest primary tumor. Median overall survival (OS) was 6.7 months, while the median progression-free survival (PFS) was 6 months. Age ( p = 0.001), gender ( p = 0.002), Eastern Cooperative Oncology Group ( p < 0.05), anatomical site ( p = 0.002), herniation ( p < 0.05), midline shift ( p = 0.002), treatment strategies ( p < 0.05), and postoperative complications (p < 0.05) significantly impacted OS, with significantly poor prognosis seen with extremes of age, male gender (hazard ratio [HR]: 2.0; 95% confidence interval [CI]: 1.3-3.1; p = 0.003), leptomeningeal lesions (HR: 5.7; 95% CI: 1.1-29.7; p = 0.037), and patients presenting with uncal herniation (HR: 3.5; 95% CI: 1.9-6.3; p < 0.05). Frontal lobe lesions had a significantly better OS (HR: 0.5; 95% CI: 0.2-1.0; p = 0.049) and PFS (HR: 0.08; 95% CI: 0.02-0.42; p = 0.003). Conclusion BM has grim prognoses, with comparable survival indices between developed countries and LMICs. Early identification of both primary malignancy and metastatic lesions, followed by judicious management, is likely to significantly improve survival.

Improving the efficacy of plant-made anti-HIV monoclonal antibodies for clinical use.

Broadly neutralising antibodies are promising candidates for preventing and treating Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS), as an alternative to or in combination with antiretroviral therapy (ART). These mAbs bind to sites on the virus essential for virus attachment and entry, thereby inhibiting entry into the host cell. However, the cost and availability of monoclonal antibodies, especially combinations of antibodies, hampers implementation of anti-HIV bNAb therapies in low- to middle- income countries (LMICs) where HIV-1 prevalence is highest. We have produced three HIV broadly neutralizing antibodies (bNAbs), 10-1074, VRC01 and 3BNC117 in the Nicotiana benthamiana transient expression system. The impact of specific modifications to enhance potency and efficacy were assessed. To prolong half-life and increase bioavailability, a M252Y/S254T/T256E (YTE) or M428L/N434S (LS) mutation was introduced. To increase antibody dependent cellular cytotoxicity (ADCC), we expressed an afucosylated version of each antibody using a glycoengineered plant line. The majority of bNAbs and their variants could be expressed at yields of up to 47 mg/kg. Neither the expression system nor the modifications impacted the neutralization potential of the bNAbs. Afucosylated bNAbs exhibit enhanced ability to bind to FcγRIIIa and trigger ADCC, regardless of the presence of Fc amino acid mutations. Lastly, we demonstrated that Fc-modified variants expressed in plants show enhanced binding to FcRn, which results in a favourable in vivo pharmacokinetic profile compared to their unmodified counterparts. Tobacco plants are suitable expression hosts for anti-HIV bNAbs with increased efficacy and an improved pharmacokinetic profile.

Health facility assessments of cervical cancer prevention, early diagnosis, and treatment services in Gulu, Uganda.

Cervical cancer is ranked globally in the top three cancers for women younger than 45 years, with the average age of death at 59 years of age. The highest burden of disease is in low-to-middle income countries (LMICs), responsible for 90% of the 311,000 cervical cancer deaths in 2018. This growing health disparity is due to the lack of quality screening and treatment programs, low human papillomavirus (HPV) vaccination rates, and high human immunodeficiency virus (HIV) co-infection rates. To address these gaps in care, we need to develop a clear understanding of the resources and capabilities of LMICs' health care facilities to provide prevention, early diagnosis through screening, and treatment for cervical cancer. This project aimed to assess baseline available cervical cancer prevention, early diagnosis, and treatment resources, at facilities designated as Health Center III or above, in Gulu, Uganda. We adapted the World Health Organization's Harmonized Health Facility Assessment for our own HFA and grading scale, deploying it in October 2021 for a cross-sectional analysis of 21 health facilities in Gulu. Grading of Health Center IIIs (n = 16) concluded that 37% had "excellent" or "good" resources available, and 63% of facilities had "poor" or "fair" resources available. Grading of Health Center IVs and above (n = 5) concluded that 60% of facilities had "excellent" or "good" resources, and 40% had "fair" resources available. The analysis of health facilities in Gulu demonstrated subpar resources available for cervical cancer prevention, early diagnosis, and treatment. Focused efforts are needed to expand health centers' resources and capability to address rising cervical cancer rates and related health disparities in LMICs. The development process for this project's HFA can be applied to global cervical cancer programming to determine gaps in resources and indicate areas to target improved health equity.

The Burden and In-Hospital Mortality of Stroke Admissions at a Tertiary Level Hospital in Namibia: A Retrospective Cohort Study.

Despite stroke being a leading cause of morbidity and mortality globally, there is a dearth of information on the burden and outcomes of stroke in sub-Saharan Africa and Namibia in particular. A hospital-based, retrospective cohort study was conducted to analyse non-electronic medical records of all consecutive stroke patients who were admitted to one of the highest tertiary-level hospitals in Namibia for 12 months (2019-2020). The primary outcome of the study was to establish the in-hospital mortality, stroke subtypes, and associated complications. In total, 220 patients were included in the study, their mean age was 53 (SD13.8) years, and 55.5% were males. 61.0% had an ischaemic stroke (IS), and 39.0% had a haemorrhagic stroke (HS). The mean age was significantly lower in patients with HS vs. IS (48.2 ± 12.2 vs. 56.1 ± 13.3, p < 0.001). Of the IS patients, the majority (29.0%) had total anterior circulation infarct (TACI), while in the HS group, 34.0% had basal ganglia haemorrhage with or without intraventricular extension. Hypertension (p = 0.015), dyslipidaemia (p = 0.001), alcohol consumption (p = 0.022), and other cardiovascular diseases (p = 0.007) were more prevalent in patients with IS compared to those with HS. The prevalence rate of intravenous thrombolysis was 2.2% in IS and use of intravenous antihypertensives in 25.9% of patients with HS than IS. The in-hospital mortality was 26.4% with complications such as raised ICP, aspiration pneumonia, hydrocephalus, and sepsis significantly high in those that died. Aspiration pneumonia (OR 2.79, 95% CI 1.63-4.76, p < 0.001) and increased ICP (OR 0.30, 95% CI 0.16-057, p < 0.001) were independent predictors of in-hospital mortality on the multivariate analysis. Our findings showed a younger mean age for stroke and mortality rate comparable to other low- to middle-income countries (LMICs). Hypertension and alcohol consumption were the main risk factors for both stroke subtypes, while aspiration pneumonia and raised intracranial pressure predicted in-hospital mortality.

Endocrine Abnormalities in Children With Traumatic Brain Injury at a Tertiary Care Center.

Objective Accidental traumatic brain injury (TBI) can lead to severe complications such as endocrine abnormalities and long-term morbidities and can negatively impact patient lives. These conditions are also associated with a high cost of treatment over a lifetime, a significant concern in low-to-middle-income countries (LMICs). In Pakistan, the prevalence of children with endocrine abnormalities secondary to TBI remains largely unexplored. We conducted a retrospective cross-sectional study to estimate the burden of endocrine abnormalities due to TBI among children in our population. Methods Twenty patients previously admitted with head injury between September and October 2019 were retrospectively reviewed with tests for baseline serum sodium, plasma osmolality, cortisol, adrenocorticotropin (ACTH), free thyroxine (fT4), growth hormone (GH), insulin growth factor-1 (IGF-1), follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid-stimulating hormone (TSH), prolactin, estradiol, and testosterone. Data were collated from the electronic Health and Information Management System (HIMS) and analyzed using SPSS v25. Chi-square and t-tests were used to identify associations between variable groups. Outcomes of interest included correlations between hormonal levels and demographic factors, interventions and hormonal levels, and complication rates and hormonal levels. Results Our study reports three (15% of the total cohort) patients with pituitary hormone deficits (two with low IGF-1 and one with low TSH). High serum IGF-1 and ACTH levels were also observed in three (15%) children. High IGF-1 was associated with female gender (p=0.007), mechanical ventilation (p=0.038), and falls (p=0.028). IGF-1 (p=0.035) and GH (p=0.049) levels were associated with improvement in Extended Glasgow Outcome Scale (GOS-E) score. Testosterone was positively correlated with a high percentile for height (p=0.005) and GOS-E scores on follow-up (p=0.030). High testosterone levels (592.12 ± 102.28 ng/dl) were associated with good functional outcomes in post-pubescent patients (p<0.05). Serum fT4 was linked with a high GOS-E score at discharge in prepubescent patients (p=0.034). Neurosurgical decompression was the only risk factor for hormone deficiency, comprising 67% of the group with hormone deficiencies (p=0.028). The learning difficulties were observed exclusively in children with hormonal deficiencies (7 patients, p=0.000). Conclusion Hormonal dysfunction due to TBI in children can lead to poor outcomes. High serum IGF-1, testosterone, and free T4 levels were associated with improved functional outcomes in children with TBI. Limited follow-up and resources in LMICs are significant barriers to addressing the morbidity associated with these conditions and need to be addressed at a health policy level.

Limiting the Spread of Multidrug-Resistant Bacteria in Low-to-Middle-Income Countries: One Size Does Not Fit All.

The spread of multidrug-resistant organisms (MDRO) is associated with additional costs as well as higher morbidity and mortality rates. Risk factors related to the spread of MDRO can be classified into four categories: bacterial, host-related, organizational, and epidemiological. Faced with the severity of the MDRO predicament and its individual and collective consequences, many scientific societies have developed recommendations to help healthcare teams control the spread of MDROs. These international recommendations include a series of control measures based on surveillance cultures and the application of barrier measures, ranging from patients' being isolated in single rooms, to the reinforcement of hand hygiene and implementation of additional contact precautions, to the cohorting of colonized patients in a dedicated unit with or without a dedicated staff. In addition, most policies include the application of an antimicrobial stewardship program. Applying international policies to control the spread of MDROs presents several challenges, particularly in low-to-middle-income countries (LMICs). Through a review of the literature, this work evaluates the real risks of dissemination linked to MDROs and proposes an alternative policy that caters to the means of LMICs. Indeed, sufficient evidence exists to support the theory that high compliance with hand hygiene and antimicrobial stewardship reduces the risk of MDRO transmission. LMICs would therefore be better off adopting such low-cost policies without necessarily having to implement costly isolation protocols or impose additional contact precautions.

Colorectal Cancer: A Systematic Review of the Current Situation and Screening in North and Central Asian Countries.

The prevalence of colorectal cancer (CRC) is increasing in the past few decades. A significant proportion of this increase is from low to middle income countries (LMIC). CRC prevalence is also increasing in North and Central Asian Countries (NCAC). Screening for colorectal cancer has decreased CRC mortality but data regarding screening practices in NCAC is limited. A literature search was conducted in PubMed/Medline, Embase and Cochrane for current colorectal cancer screening practices in NCAC. Incidence and mortality rates were derived from public health agency websites to calculate age-standardized CRC mortality-to-incidence ratios. Web-based online break-point testing defined as statistical major changes in CRC mortality trends was completed. Among the 677 screened studies, 37 studies met the criteria for inclusion for review. CRC screening in NCAC is not organized, although most countries have cancer registries. The data availability is scarce, and most data is prior to 2017. Most studies are observational. There is minimal data about colonoscopy preparations, adenoma detection and complications rates. The polyp detection rates (PDRs) and adenoma detection rates (ADRs) seem low to optimal in this region. Commonly measured outcomes include participation rate, fecal immunochemical tests (FIT) positivity rate and cost-benefit measures. Lower mortality-to-incidence ratios is seen in countries with screening programs. Kazakhstan and Lithuania with screening programs have achieved breakpoint suggesting major changes in CRC mortality trends. Data about CRC screening varies widely within NCAC. High human developmental index (HDI) countries like Lithuania and Estonia have higher incidence of CRC and mortality. Seven NCAC have CRC screening programs with most utilizing non-invasive methods for screening. Data collection is regional and not organized. The ADR and PDR are low to optimal in this region and cancer detection rates are comparable to other high-income countries (HIC).CRC detection rate is 0.05% for screening in Kazakhstan and 0.2% for screening in Lithuania. Very limited information is available on the actual cost and logistics of implementing a CRC screening program. All NCAC have a cancer registry, with some having a high-quality registry showing national coverage with good validity and completeness.Establishing guideline-based registries and increasing screening efficacy could improve CRC outcomes in NCAC.

Modern advances in epilepsy imaging used on the basis of cost: A review

Epilepsy is a chronic neurologic condition that affects social behavior, health, the economy, and social functioning. Worldwide, an estimated 5 million people are diagnosed with epilepsy each year. More than 50 million people are reportedly affected globally. 49% of epilepsy patients live in low-to middle-income countries; in exceptional situations, this number may reach 139/100,000 people. This review provides imaging therapy used for the diagnoses which are compared according to the cost of individual imaging techniques reliable or affordable for the patient. The main tools used to evaluate patients with epilepsy are electroencephalography (EEG), and the functional imaging modalities for epilepsy are positional emission tomography, single-photon emission computed tomography (CT), tissue ablation using high-intensity focused ultrasound, deep non-invasive neuromodulation, and blood–brain barrier opening using superficial targets, focused ultrasound, magnetoencephalography (MEG), and magnetic resonance imaging (MRI). In the differential diagnosis imaging findings, the treatment of epilepsy is significantly better. By comparing the one-time cost of all imaging techniques, the three techniques mostly used are CT, MRI, and EEG. Patients may easily access and afford these imagining techniques because they are readily available at low cost which lies between 1000 and 10,000 rupees.

Techno-Economic Evaluation of Novel SARS-CoV-2 Vaccine Manufacturing in the Insect Cell Baculovirus Platform

The need to increase the COVID-19 vaccine manufacturing capacity at low to middle-income countries (LMIC) led to a growing focus on Novavax (NVX-CoV2373), a thermostable protein subunit vaccine manufactured using a baculovirus and insect cell system (BICS) platform. This study aimed to conduct a techno-economic analysis to assess the BICS platform of vaccine manufacturing and compare it to the mRNA and the saRNA platform. The data from the Novavax patent for the COVID-19 vaccine formulation and the manufacturing steps were used to simulate the BICS vaccine production in SuperPro Designer. From the techno-economic analysis, the productivity of all platforms was compared in terms of doses/day per L production scale. The saRNA platform’s productivity is about 1,000-fold of the BICS platform and 20-fold of the mRNA platform. BICS is a feasible option for LMIC to produce vaccines because the cost per dose is like the saRNA platform, while the mRNA platform’s cost per dose is 7 times higher than the BICS and saRNA platforms. However, further optimization is necessary to improve the productivity of the BICS platform to match saRNA’s platform.

Risk and protective factors for dementia: epidemiological evidence and windows of opportunity

AbstractBackgroundMost people with dementia already live in low‐ to middle‐income countries (LMIC). However, most evidence regarding dementia prevention comes from high‐income countries that have different socioeconomic status (SES) and risk factors prevalence than LMIC. In this session, we will present results on risk and protective factors for dementia from the Longitudinal Study of Adult Health (ELSA‐Brasil), the Brazilian Longitudinal Study of Aging (ELSI‐Brazil), and the Brazilian Biobank for Aging Studies (BAS).MethodThe ELSA‐Brasil follows 15,105 public servants since 2008‐10. The ELSI‐Brazil is a nationally representative study with 9,412 adults aged 50 years and older, who were enrolled in 2015‐16. The BAS is a neuropathology study that started in 2004 and is the largest brain bank in Latin America with a collection of 1,441 brains. The focus of this presentation will be on the associations of education, SES, and cardiovascular factors with dementia using data from these three studies.ResultIn the BAS, 77% of the sample has less than 5 years of education and 56% unskilled occupations. Compared to the group without education, those with formal education had better cognitive performance (1‐4 years: 𝛽 = ‐0.99, 95%CI = –1.85; –0.14, p = 0.02; ≥5 years: = –1.42, 95% CI = –2.47; –0.38, p = 0.008). On the other hand, occupation complexity and demands were unrelated to cognition. Similarly, we showed that education and early‐life SES were the main contributors to cognitive performance in the ELSA‐Brasil, while later SES had a lower influence on cognitive scores. Cardiovascular factors are also important contributors to brain health. Ideal vascular health was related to better cognitive function in the ELSA‐Brasil. Participants with intermediate (β = 0.064, 95%CI = 0.033; 0.096) and optimal health (β = 0.108, 95%CI = 0.052; 0.164) had better cognitive z‐scores. Moreover, carotid artery atherosclerosis evaluated by morphometric measurements was related to cognitive impairment in BAS and with cognitive decline in the ELSA‐Brasil after 8 years of follow‐up (β = ‐0.028, 95%CI = ‐0.036; ‐0.020, p&lt;0.001). Finally, hypertension was related to worse cognition (β = ‐0.09; 95%CI = ‐0.15, ‐0.04; p = 0.001) in ELSI‐Brazil, mainly in non‐frail participants.ConclusionStudies from LMIC regarding dementia risk factors are essential to implement tailored public policies for dementia primary prevention.

Technical aspects of inguino scrotal hernia surgery in developing countries.

Technical aspects of inguinoscrotal herniorrhaphy performed in low to middle income countries (LMICs) are described here to help surgeons who will operate on these challenging hernias in austere settings. Technical considerations related to operative repair were delineated with the consensus of 7 surgeons with extensive experience in inguinoscrotal hernia repair in LMICs. Important steps and illustrations were prepared accordingly. The anatomical and pathologic differences and technical implications of operating in limited resource settings are emphasized with suggestions to approach anticipated challenges. Pre-operative evaluation, anesthetic considerations, and technical guidelines are offered in context. The authors have cumulatively performed over 1775 inguinoscrotal Lichtenstein operations in LMICs. While dedicated, reliable, long-term follow-up is unavailable from LMICs, one author reports outcomes with 5year follow-up from the HerniaMed registry using the identical technique in similarly classed hernias. In 90 inguinoscrotal Lichtenstein repair patients (78.3% follow-up), there was one recurrence, low rates of chronic pain (2.2% at rest, 4.4% with activity), and low rates of reintervention (1.1%). There is a difference between inguinal hernias found in LMICs and those seen in high-income countries with larger, chronic, and more technically challenging pathology. The consequences of intra-operative complications can be catastrophic in a LMIC. Technical measures are offered to improve outcomes, avoid and manage complications, and provide optimal care to this important population.

Final Report of a Novel and Successful Online Pubic Health Capacity Building Experiment – Peoples-uni

The People’s Open Access Education Initiative (Peoples-uni) was established as an educational charity to help reduce inequalities in access to the higher education required to build Public Health capacity through workforce development for health professionals in low- to middle-income countries (LMICs). Online learning, using open source software, Open Educational Resources and an international cadre of volunteer tutors, underpinned a low cost programme which produced a number of successful outcomes including university validated master’s level awards, continuing professional development, positive feedback from students, and the application by alumni of skills learned. Peoples-uni closed in 2021, its programme taken over by another organisation, and this paper builds on previous reports to summarise the experience and draw lessons for others who may wish to contribute in a similar way.

Current status of post-traumatic brain injury rehabilitation care in LMI Southeast Asian Countries: A mini systematic review

Low-to-middle income countries (LMICs) in Southeast Asia (SEA) had the highest global traumatic brain injury (TBI). However, post-TBI rehabilitation care may be limited in these countries, thereby contributing to the poorer quality of life (QoL) of patients with TBI. The present systematic review aimed to elucidate the current status of post-TBI rehabilitation care in the LMICs in the SEA region and to discuss the limitations that may hinder the advancement of TBI rehabilitation within this region. A literature search was carried out using five databases (PubMed, Ovid MEDLINE, EMBASE, CINAHL and Scopus), and the final number of articles were selected according to the PRISMA guidelines. This review selected four relevant research articles from Malaysia and Thailand for critical appraisal. These articles showed that the status of post-TBI rehabilitation care in these regions remains unclear based on the scarcity of available literature. Only early rehabilitation care strategies have been discussed in the literature, such as individualised structured cognitive rehabilitation, utilisation of humanoid robots and the implementation of sensory stimulation programs. This review also suggested that TBI rehabilitation improvements may be hindered by a lack of government funding, unequal distribution of care services and reliance on traditional care. Thus, more research into TBI rehabilitation care is significantly needed within the SEA region to overcome these barriers, leading to the preservation of patients’ QoL.

Can Expired Drugs be Used Ethically in Low- to Middle-Income Countries: Treating Pediatric Hemophilia

Health inequities in pediatric subspecialty care in low- to middle-income countries (LMICs) are a long-standing challenge due to limited subspecialty providers, expensive pharmacologic treatments, and barriers to accessing treatment centers.1-3 Without providing specialty care to children worldwide, we perpetuate global inequities. Efforts have been made to provide short-term surgical and medical brigades to countries who lack the financial means to establish specialty centers.4-7 Larger-scale programs have brought together clinicians to provide education to health providers and educational institutions to reduce the global inequality in pediatric subspecialty care.

Asset building policies to lift the resource curse: child development accounts in oil-and-gas-rich countries

Of the approximately 70 low-to-middle-income (LMI) oil-and-gas-rich countries, almost all are victims of the resource curse or paradox of plenty, which conceptualizes the development patterns with petroleum and mineral resources. Lifting the resource curse can positively change the trajectory of global development. After the failure of the implementation of natural reserve funds in most oil-and-gas-rich LMI countries, scholars suggested the direct distribution of natural resource revenues to the population to escape the resource curse. The paper suggests an evidence-based asset-building policy, child development accounts (CDA), linked to oil and gas revenues being directly distributed to the population. CDAs are saving accounts specifically targeting children, started in the late 1980s, to help families to fulfill life goals for their children such as postsecondary education, homeownership, business development, and retirement security. The elements of the recommended policy are based on the findings of three qualitative studies carried out in Azerbaijan in 2017 and 2018, and in six post-Soviet countries in 2019 and 2020. Primary data were collected through in-depth interviews with key informants (N = 94), such as ministers, deputy ministers, representatives of the oil funds, academicians, financial institutions, and local and international nonprofit organizations. Secondary data came from archival records, such as governmental reports, publications from national and international agencies, published research, and statistics from relevant government agencies. Purposive sampling techniques were used. The inclusion criteria were being a senior policy-maker, having a deep understanding of the policy-making process, and having deep knowledge of social protection and child well-being systems in Azerbaijan. The data were analyzed by NVivo. The paper used 10 CDA design elements recommended by Michael Sherraden and his colleagues as well as national CDA policy models from across the globe. Azerbaijan, an oil-and-gas-rich LMI country was chosen as a case study for the recommended policy design

Genomic selection strategies to increase genetic gain in tea breeding programs.

Tea [Camellia sinensis (L.) O. Kuntze] is mainly grown in low- to middle-income countries (LMIC) and is a global commodity. Breeding programs in these countries face the challenge of increasing genetic gain because the accuracy of selecting superior genotypes is low and resources are limited. Phenotypic selection (PS) is traditionally the primary method of developing improved tea varieties and can take over 16yr. Genomic selection (GS) can be used to improve the efficiency of tea breeding by increasing selection accuracy and shortening the generation interval and breeding cycle. Our main objective was to investigate the potential of implementing GS in tea-breeding programs to speed up genetic progress despite the low cost of PS in LMIC. We used stochastic simulations to compare three GS-breeding programs with a Pedigree and PS program. The PS program mimicked a practical commercial tea-breeding program over a 40-yr breeding period. All the GS programs achieved at least 1.65 times higher genetic gains than the PS program and 1.4 times compared with Seed-Ped program. Seed-GSc was the most cost-effective strategy of implementing GS in tea-breeding programs. It introduces GS at the seedlings stage to increase selection accuracy early in the program and reduced the generation interval to 2yr. The Seed-Ped program outperformed PS by 1.2 times and could be implemented where it is not possible to use GS. Our results indicate that GS could be used to improve genetic gain per unit time and cost even in cost-constrained tea-breedingprograms.

Systematic Review of mHealth Interventions for Adolescent and Young Adult HIV Prevention and the Adolescent HIV Continuum of Care in Low to Middle Income Countries

Adolescents and young adults (AYA) in low to middle income countries (LMIC) have poorer outcomes along each step in the HIV continuum of prevention and care compared to younger children or older adults. The use of mHealth technology provides a potentially promising implementation strategy for interventions to remedy these disparities. We therefore conducted a systematic review of the English literature and conference proceedings from January 1, 2000 to April 1, 2021 evaluating mHealth interventions targeting AYA along each step of the HIV continuum of care in LMIC. We identified 27 mHealth interventions across the HIV continuum, with no interventions addressing transition from pediatric to adult care. The majority of studies were single arm, uncontrolled or underpowered, with few randomized trials resulting in mixed and inconclusive outcomes. mHealth interventions have potential to remedy disparities along the HIV continuum of care for AYA in LMIC but larger, powered randomized trials are needed.

Innovations and adaptations in neonatal and pediatric respiratory care for resource constrained settings.

Respiratory disease is a leading cause of death in children under 5 years of age worldwide, and most of these deaths occur in low- to middle-income countries (LMICs) where advanced respiratory care technology is often limited. Much of the equipment required to provide advanced respiratory care is unavailable in these areas due to high costs, the need for specialty trained personnel, and myriad other resource constraints that limit uptake and sustainable use of these devices, including reliable access to electricity, sensitive equipment needing frequent maintenance, single-patient-use supplies, and lack of access to sterilization equipment. Compounding the problem, pediatrics is uniquely challenging in that one size does not fit all, or even most patients. Despite these substantial barriers, numerous innovations in respiratory care technology have been made in recent years that have brought increasing access to high quality respiratory care in some of the most remote areas of the world. In this article, we intend to review the global burden of respiratory diseases for children, highlight the prototypical innovations that have been made in bringing respiratory care to LMICs, spotlight some of the technologies being actively developed to improve respiratory care in resource-constrained settings, and conclude with a discussion highlighting areas where further innovation is still needed.

Experiences and Perceptions of Telephone-delivery of the Common Elements Treatment Approach for Mental Health Needs Among Young People in Zambia During the COVID-19 Pandemic.

BackgroundMental and behavioral health needs are immense in low-to-middle income countries (LMIC), particularly for adolescents and young adults (AYA). However, access to mental health services is limited in LMIC due to barriers such as distance to a health care site, low number of providers, and other structural and logistical challenges. During the COVID-19 pandemic, these barriers were significantly exacerbated and, thus, mental health services were severely disrupted. A potential solution to some of these barriers is remote delivery of such services via technology. Exploration of AYA experiences is needed to understand the benefits and challenges when shifting to remotely delivered services.MethodsParticipants included 16 AYA (15–29 years) residing in Lusaka, Zambia who met criteria for a mental or behavioral health concern and received telehealth delivery of the Common Elements Treatment Approach (CETA). AYA participated in semi-structured qualitative interviews to explore feasibility, acceptability, and barriers to telephone-delivered treatment in this context. Thematic coding analysis was conducted to identify key themes.FindingsThree major response themes emerged: 1) Advantages of telehealth delivery of CETA, Disadvantages or barriers to telehealth delivery of CETA, 3) AYA recommendations for optimizing telehealth (ways to improve telehealth delivery in Zambia. Results indicate that logistical and sociocultural barriers i.e., providing AYA with phones to use for sessions, facilitating one face-to-face meeting with providers) need to be addressed for success of remotely delivered services.ConclusionAYA in this sample reported telehealth delivery reduces some access barriers to engaging in mental health care provision in Zambia. Addressing logistical and sociocultural challenges identified in this study will optimize feasibility of telehealth delivery and will support the integration of virtual mental health services in the Zambian health system.
