The World Health Organization (WHO) monitors the spread of diseases globally and maintains a list of diseases with epidemic or pandemic potential. Currently listed diseases include Chikungunya, cholera, Crimean-Congo hemorrhagic fever, Ebola virus disease, Hendra virus infection, influenza, Lassa fever, Marburg virus disease, Neisseria meningitis, MERS-CoV, monkeypox, Nipah virus infection, novel coronavirus (COVID-19), plague, Rift Valley fever, SARS, smallpox, tularemia, yellow fever, and Zika virus disease. The associated pathogens are increasingly important on the global stage. The majority of these diseases have neurological manifestations. Those with less frequent neurological manifestations may also have important consequences. This is highlighted now in particular through the ongoing COVID-19 pandemic and reinforces that pathogens with the potential to spread rapidly and widely, in spite of concerted global efforts, may affect the nervous system. We searched the scientific literature, dating from 1934 to August 2020, to compile data on the cause, epidemiology, clinical presentation, neuroimaging features, and treatment of each of the diseases of epidemic or pandemic potential as viewed through a neurologist's lens. We included articles with an abstract or full text in English in this topical and scoping review. Diseases with epidemic and pandemic potential can be spread directly from human to human, animal to human, via mosquitoes or other insects, or via environmental contamination. Manifestations include central neurologic conditions (meningitis, encephalitis, intraparenchymal hemorrhage, seizures), peripheral and cranial nerve syndromes (sensory neuropathy, sensorineural hearing loss, ophthalmoplegia), post-infectious syndromes (acute inflammatory polyneuropathy), and congenital syndromes (fetal microcephaly), among others. Some diseases have not been well-characterized from a neurological standpoint, but all have at least scattered case reports of neurological features. Some of the diseases have curative treatments available while in other cases, supportive care remains the only management option. Regardless of the pathogen, prompt, and aggressive measures to control the spread of these agents are the most important factors in lowering the overall morbidity and mortality they can cause.
Background Evidence suggests that social networks improve functional recovery after stroke, but this work has not been extended to low- and middle-income countries (LMICs). Post-stroke depression interferes with functional outcome but is understudied in LMICs. Aims To determine the relationships between social networks, disability, and depressive symptoms in patients surviving 90-days post-stroke in Dar es Salaam, Tanzania. Methods Participants ≥ 18 years, admitted ≤ 14 days of stroke onset, were enrolled. Disability was measured using the modified Rankin Scale, social networks by the Berkman-Syme social network index, and depressive symptoms by the Patient Health Questionnaire-9 (PHQ-9) by telephone interview at 90 days. A Kruskal-Wallis test or Spearman's correlation coefficient was used to assess the associations between social networks, depressive symptoms, and disability. Results Of 176 participants, 43% (n = 75) died, with an additional 11% (n = 20) lost to follow-up by 90 days. Among 81 survivors, 94% (n = 76, 57% male, average age 54 years) had complete information on all scales (mean and median follow-up time of 101 and 88 days). Thirty percent (n = 23, 41.9%, 95% confidence interval 20.2) had at least mild depressive symptoms (PHQ-9 ≥ 5 points). Nearly two-thirds (n = 46, 61%) reported ≥ 3 close friends. A higher social network index score was associated with fewer depressive symptoms (p < 0.0001) and showed a trend towards significance with lower disability (p = 0.061). Higher depressive symptom burden was correlated with higher disability (r = 0.52, p < 0.0001). Conclusion Post-stroke social isolation is associated with more depressive symptoms in Tanzania. Understanding social networks and the associated mechanisms of recovery in stroke is especially relevant in the context of limited resources.
CONTEXT: Helping Babies Breathe (HBB) is a well-established neonatal resuscitation program designed to reduce newborn mortality in low-resource settings. OBJECTIVES: In this literature review, we aim to identify challenges, knowledge gaps, and successes associated with each stage of HBB programming. DATA SOURCES: Databases used in the systematic search included Medline, POPLINE, Cumulative Index to Nursing and Allied Health Literature, Latin American and Caribbean Health Sciences Literature, African Index Medicus, Cochrane, and Index Medicus. STUDY SELECTION: All articles related to HBB, in any language, were included. Article quality was assessed by using the Grading of Recommendations Assessment, Development, and Evaluation framework. DATA EXTRACTION: Data were extracted if related to HBB, including its implementation, acquisition and retention of HBB knowledge and skills, changes in provider behavior and clinical care, or the impact on newborn outcomes. RESULTS: Ninety-four articles met inclusion criteria. Barriers to HBB implementation include staff turnover and limited time or focus on training and practice. Researchers of several studies found HBB cost-effective. Posttraining decline in knowledge and skills can be prevented with low-dose high-frequency refresher trainings, on-the-job practice, or similar interventions. Impact of HBB training on provider clinical practices varies. Although not universal, researchers in multiple studies have shown a significant association of decreased perinatal mortality with HBB implementation. LIMITATIONS: In addition to not conducting a gray literature search, articles relating only to Essential Care for Every Baby or Essential Care for Small Babies were not included in this review. CONCLUSIONS: Key challenges and requirements for success associated with each stage of HBB programming were identified. Despite challenges in obtaining neonatal mortality data, the program is widely believed to improve neonatal outcomes in resource-limited settings.
The 90-day mortality of stroke presenting at MNH is 50%, much higher than in higher income settings. Although severe stroke presentations are a major factor, efforts to improve the quality of care and prevent complications of stroke are urgently needed. Acute stroke interventions with low number needed to treat represent challenging long-term goals.
Patient-centeredness (including interpersonal relationships), organizational factors, and location are important individual determinants of satisfaction for women seeking maternal care at study facilities. Understanding variation in these factors should inform QI efforts in maternal and newborn health programs.
Summary Objective: To assess the economic impact of epilepsy in Bhutan, a lower-middle-income country with a universal health care system, but with limited access to neurological care. Methods: A cross-sectional survey was conducted of patients with epilepsy receiving care at Jigme Dorji Wangchuk National Referral Hospital from January to August, 2016. Data were collected on clinical features of epilepsy, cost of care, impact of epilepsy on school or work, and household economic status of participants and matched comparisons (a sibling or neighbor from a separate household without epilepsy). Results: A total of 172 individuals were included in the study (130 adults and 42 children). One-third of adults and 20 (48%) children had seizures at least once per month. Mean annual direct out-of-pocket costs for epilepsy care was 6,054 BTN (91 USD), of which transportation formed the greatest portion (53%). Direct costs of epilepsy were an average of 3.2% of annual household income. Adults missed 6.8 ± 9.0 days of work or school per year on average, and children missed 18.6 ± 34.7 days of school. Of adult participants, 23 (18%) abandoned employment or school because of epilepsy; among school-age children, seven (18%) stopped school because of epilepsy. Households with a person with epilepsy had lower monthly per-person income (6,434 BTN) than comparison households without epilepsy (8,892 BTN; p = 0.027). Significance: In this lower-middle-income country, despite universal health care services, households of people with epilepsy face a significant economic burden. Cost of transportation for epilepsy care contributes a major proportion of the direct cost burden. Indirect costs, including negative effects on school achievement and employment, disrupt the economic potential of people with epilepsy in Bhutan. Household economic well-being is impacted by the direct and indirect costs of epilepsy.
ObjectiveEpilepsy affects approximately 50 million people globally, with approximately 80% living in low/middle-income countries (LMIC), where access to specialist care is limited. In LMIC, primary health workers provide the majority of epilepsy care, despite limited training in this field. Recognising this knowledge gap among these providers is an essential component for closing the epilepsy treatment gap in these regions.SettingIn Zambia, the vast majority of healthcare is provided by clinical officers (COs), primary health providers with 3 years post-secondary general medical education, who predominantly work in first-level health centres around the country.ParticipantsWith cooperation from the Ministry of Health, a total of 10 COs from 4 surrounding first-level health centres around the capital city of Lusaka participated, with 9 completing the entire course.InterventionCOs were trained in a 3-week structured course on paediatric seizures and epilepsy, based on adapted evidence-based guidelines.ResultsPreassessment and postassessment were conducted to assess the intervention. Following the course, there was improved overall knowledge about epilepsy (69% vs 81%, p<0.05), specifically knowledge regarding medication management and recognition of focal seizures (p<0.05), improved seizure history taking and appropriate medication titration (p<0.05). However, knowledge regarding provoked seizures, use of diagnostic studies and general aetiologies of epilepsy remained limited.ConclusionsThis pilot project demonstrated that a focused paediatric epilepsy training programme for COs can improve knowledge and confidence in management, and as such is a promising step for improving the large epilepsy treatment gap in children in Zambia. With feasibility demonstrated, future projects are needed to expand to more rural regions for more diverse and larger sample of primary health provider participants and encompass more case-based training and repetition of key concepts as well as methods to improve and assess long-term knowledge retention.
We adapted a method from developmental psychology [1] to explore whether capuchin monkeys (Cebus apella) would place objects on a “blicket detector” machine to diagnose causal relations in the absence of a direct reward. Across five experiments, monkeys could place different objects on the machine and obtain evidence about the objects’ causal properties based on whether each object “activated” the machine. In Experiments 1–3, monkeys received both audiovisual cues and a food reward whenever the machine activated. In these experiments, monkeys spontaneously placed objects on the machine and succeeded at discriminating various patterns of statistical evidence. In Experiments 4 and 5, we modified the procedure so that in the learning trials, monkeys received the audiovisual cues when the machine activated, but did not receive a food reward. In these experiments, monkeys failed to test novel objects in the absence of an immediate food reward, even when doing so could provide critical information about how to obtain a reward in future test trials in which the food reward delivery device was reattached. The present studies suggest that the gap between human and animal causal cognition may be in part a gap of motivation. Specifically, we propose that monkey causal learning is motivated by the desire to obtain a direct reward, and that unlike humans, monkeys do not engage in learning for learning’s sake.
