Chronic kidney disease in Ecuador: An epidemiological and health system analysis of an emerging public health crisis.

The absence of a chronic kidney disease (CKD) registry in Ecuador makes it difficult to assess the burden of disease, but there is an anticipated increase in the incidence of CKD along with increasing diabetes, hypertension and population age. From 2012, augmented funding for renal replacement therapy expanded dialysis clinics and patient coverage. We conducted 73 in-depth sociological interviews with healthcare providers in eight provinces and collected quantitative epidemiological data on patients with CKD diagnoses from six national-level databases between 2015 and 2018. Datasets show a total of 17,484 dialysis patients in 2018, or 567 patients per million population (pmp), with an annual cost exceeding 11% of Ecuador's public health budget. Each year, there were 139-162 pmp new dialysis patients, while doctors reported waiting lists. The number of patients on peritoneal dialysis was static; those on hemodialysis increased over time. Only 13 of 24 provinces were found to have dialysis services, and nephrologists were clustered in major cities, which limits access, delays medical attention, and adds a travel burden on patients. Prevention and screening programs are scarce, while hospitalization is an important reality for CKD patients. CKD is an emerging public health crisis that has increased dramatically over the last decade in Ecuador and is expected to continue, making coverage for all patients impossible and the current structure, unsustainable. A patient registry would help health policymakers and administrators estimate the demand and progression of patients with consideration for comorbidities, disease stage, requirements and costs, mortality and follow-up. This should be used to help identify where to focus prevention and improved treatment efforts. Organized monitoring of CKD patients would benefit from improvements in patient referral. Community-based education and prevention programs, the strengthening of primary healthcare capacity (including basic routine tests) and improved nephrology services are also urgently needed.

Poliovirus immunity among adults in the Democratic Republic of the Congo: a cross-sectional serosurvey.

BACKGROUND: Vaccination efforts to eradicate polio currently focus on children under 5 years of age, among whom most cases of poliomyelitis still occur. However, in the Democratic Republic of the Congo (DRC), an outbreak of wild poliovirus type 1 occurred in 2010-2011 in which 16% of cases occurred among adults; in a related outbreak in the neighboring Republic of Congo, 75% of cases occurred among the same adult age-group. Given that infected adults may transmit poliovirus, this study was designed to assess adult immunity against polioviruses. METHODS: We assessed poliovirus seroprevalence using dried blood spots from 5,526 adults aged 15-59 years from the 2013-2014 Demographic and Health Survey in the DRC. RESULTS: Among adults in the DRC, 74%, 72%, and 57% were seropositive for neutralizing antibodies for poliovirus types 1, 2, and 3, respectively. For all three serotypes, seroprevalence tended to be higher among older age groups, those living in households with more children, and among women. CONCLUSIONS: Protection against poliovirus is generally low among adults in the DRC, particularly for type 3 poliovirus. The lack of acquired immunity in adults suggests a potentially limited poliovirus circulation over the lifetime of those surveyed (spanning 1954 through 2014) and transmission of vaccine-derived poliovirus in this age group while underscoring the risk of these outbreaks among adults in the DRC.

Adapting acute malnutrition treatment protocols in emergency contexts: a qualitative study of national decision-making.

BACKGROUND: Each year, an estimated 17 million children suffer from severe acute malnutrition (SAM) and 33 million from moderate acute malnutrition (MAM), with many of the most severe cases found in extremely food insecure contexts or conflict situations. Current global outpatient treatment protocols for uncomplicated SAM and MAM, adapted by most countries for use at national level, call for SAM and MAM to be managed separately, however global-level stakeholders have recently begun evaluating simplified and/or combined protocols managing acute malnutrition. METHODS: This study analyzes national policy discussions and decision-making around outpatient acute malnutrition treatment for uncomplicated cases in emergency situations in Niger, Nigeria, Somalia, and South Sudan. Data collection (March-July 2018) included semi-structured in-depth interviews with 50 respondents (N = 11-15 per country) from government, funding agencies, and implementing partners, as well as 11 global and regional stakeholders. We also conducted a document analysis (N = 10-15 per country and at global level) to situate debates and evaluate current policy. Data were analyzed iteratively using thematic content analysis. RESULTS: We find that while combined/simplified protocols for outpatient management of uncomplicated cases of acute malnutrition are being used in emergency situations in all four countries, there is widespread confusion about protocol terminology and content, stemming from a lack of coherence at the global level. As a result, national-level stakeholders express diverse, if overlapping, rationales for modifying current protocols, which vary given the intensity and scope of the emergency. Without specific global-level guidance, combined/simplified protocols are often used on an ad hoc basis, although the processes for triggering them were at least nominally controlled at the national level. Decisions about when and where to enact "exceptional" modifications to country protocols were often based on inconsistent determinations of what constitutes an "emergency." Respondents said more evidence is needed on both clinical and operational aspects of these protocols, and they awaited clear guidance from global norm-setting agencies. CONCLUSIONS: Based on these findings, global-level stakeholders should urgently improve coordination and communication around existing protocols. Standardized guidance based on the available evidence is required to clarify best practices for combined management of SAM and MAM, particularly in emergency contexts (which should be defined) and in situations of limited resources. Given the complexity of governance arrangements in conflict situations, both guidance and updates on research must be disseminated in a rational, systematic, and digestible way to the multiplicity of field actors.

Combined protocol for severe and moderate acute malnutrition in emergencies: Stakeholders perspectives in four countries.

Each year, acute malnutrition affects an estimated 52 million children under 5 years of age. Current global treatment protocols divide treatment of severe acute malnutrition (SAM) and moderate acute malnutrition (MAM) despite malnutrition being a spectrum disease. A proposed Combined Protocol provides for (a) treatment of MAM and SAM at the same location; (b) diagnosis using middle-upper-arm circumference (MUAC) and oedema only; (c) treatment using a single product, ready-to-use-therapeutic food (RUTF), and (d) a simplified dosage schedule for RUTF. This study examines stakeholders' knowledge of and opinions on the Combined Protocol in Niger, Nigeria, Somalia, and South Sudan. Data collection included a document review followed by in-depth interviews with 50 respondents from government, implementing partners, and multilateral agencies, plus 11 global and regional stakeholders. Data were analysed iteratively using thematic content analysis. We find that acute malnutrition protocols in these countries have not been substantially modified to include components of the Combined Protocol, although aspects were accepted for use in emergencies. Respondents generally agreed that MAM and SAM treatment should be provided in the same location, however they said MUAC and oedema-only diagnosis, although more field-ready than other diagnostic measures, did not necessarily catch all malnourished children and may not be appropriate for "tall and slim" morphologies. Similarly, using only RUTF presented inherent logistical advantages, but respondents worried about pipeline issues. Respondents did not express strong opinions about simplified dosage schedules. Stakeholders interviewed indicated more evidence is needed on the operational implications and effectiveness of the Combined Protocol in different contexts.
