Challenges in the Clinical Recognition of Acute Flaccid Myelitis and its Implications.

OBJECTIVES: To explore the challenges in diagnosing acute flaccid myelitis (AFM) and evaluate clinical features and treatment paradigms associated with under recognition. STUDY DESIGN: This was a retrospective multicenter study of pediatric patients (≤18 years) who were diagnosed with AFM from 2014 to 2018 using the Centers for Disease Control and Prevention's case definition. RESULTS: In 72% of the cases (126 of 175), AFM was not considered in the initial differential diagnosis (n = 108; 61.7%) and/or the patient was not referred for acute care (n = 90; 51.4%) at the initial clinical encounter, and this did not improve over time. Although many features of the presentation were similar in those initially diagnosed with AFM and those who were not; preceding illness, constipation, and reflexes differed significantly between the 2 groups. Patients with a non-AFM initial diagnosis more often required ventilatory support (26.2% vs 12.2%; OR, 0.4; 95% CI, 0.2-1.0; P = .05). These patients received immunomodulatory treatment later (3 days vs 2 days after neurologic symptom onset; 95% CI, -2 to 0; P = .05), particularly intravenous immunoglobulin (5 days vs 2 days; 95% CI, -4 to -2; P < .001). CONCLUSIONS: Delayed recognition of AFM is concerning because of the risk for respiratory decompensation and need for intensive care monitoring. A non-AFM initial diagnosis was associated with delayed treatment that could have a clinical impact, particularly as new treatment options emerge.

A social systems analysis of implementation of El Salvador's national HIV combination prevention: a research agenda for evaluating Global Health Initiatives.

BACKGROUND: Global Health Initiatives (GHIs) have been instrumental in the rapid acceleration of HIV prevention, treatment access, and availability of care and support services for people living with HIV (PLH) in low and middle income countries (LMIC). These efforts have increasingly used combination prevention approaches that include biomedical, behavioral, social and structural interventions to reduce HIV incidence. However, little research has evaluated their implementation. We report results of qualitative research to examine the implementation of a national HIV combination prevention strategy in El Salvador funded by the Global Fund to Fight AIDS, Tuberculosis and Malaria. METHODS: We conducted in-depth interviews with principal recipients of the funding, members of the Country Coordinating Mechanism (CCM) and front line peer outreach workers and their clients. We analyzed the data using a dynamic systems framework. RESULTS: El Salvador's national HIV combination prevention strategy had three main goals: 1) to decrease the sexual risk behaviors of men who have sex with men (MSM), commercial sex workers (CSW) and transgender women (TW); 2) to increase HIV testing rates among members of these populations and the proportion of PLH who know their status; and 3) to improve linkage to HIV treatment and adherence to antiretroviral therapy (ART). Intervention components to achieve these goals included peer outreach, community prevention centers and specialized STI/HIV clinics, and new adherence and retention protocols for PLH. In each intervention component, we identified several factors which reinforced or diminished intervention efforts. Factors that negatively affected all intervention activities were an increase in violence in El Salvador during implementation of the strategy, resistance to decentralization, and budget constraints. Factors that affected peer outreach and sexual risk reduction were the human resource capacity of grassroots organizations and conflicts of the national HIV strategy with other organizational missions. CONCLUSIONS: Overall, the national strategy improved access to HIV prevention and care through efforts to improve capacity building of grass roots organizations, reduced stigma, and improved coordination among organizations. However, failure to respond to environmental and organizational factors limited the intervention's potential impact.
