Characteristics and mortality of Mexican patients with COVID-19 and mechanical ventilation.

INTRODUCTION: COVID-19-associated mortality in patients who require mechanical ventilation is unknown in the Mexican population. OBJECTIVE: To describe the characteristics of Mexican patients with COVID-19 who required mechanical ventilation. METHODS: Observational cohort study carried out in an intensive care unit from March 25 to July 17, 2020. Data were obtained from a prospective database and electronic medical records, and were analyzed with the chi-square test, Fisher's exact test or Mann-Whitney's U-test. RESULTS: One hundred patients required mechanical ventilation; median age was 56 years, 31 % were females and 97 % were Latin American. Most common comorbidities were obesity (36 %), diabetes (26 %), hypertension (20 %), and chronic or end-stage kidney disease (10 %). At the end of the analysis, 11 patients remained in the ICU, 31 had been discharged alive and 58 (65.2 %) died; survivors were younger, had lower scores on severity and organ dysfunction scales, lower levels of C-reactive protein at ICU admission, were less likely to receive hemodialysis and vasopressors, and had longer hospital and ICU stays. CONCLUSIONS: This study adds information on the presentation and results of SARS-CoV-2-infected patients who require mechanical ventilation.

Characterization of patients with autoimmune hepatitis at an university hospital in Medellín-Colombia: cohort study. / Caracterización de los pacientes con hepatitis autoinmune de un hospital universitario, Medellín-Colombia: estudio de cohorte.

INTRODUCTION: Autoimmune hepatitis is a chronic liver disease that impacts on morbidity and mortality of patients. Few epidemiological data exist of this in Latin America and Colombia. OBJECTIVES: The aim of this study is to describe the demographic, clinical and laboratory characteristics of the patients; the treatment and the response to it, the evolution and course of the disease, requirement of liver transplantation and mortality. METHODS: Historical cohort study that include patients attended at an University Hospital in Medellin, Colombia between January 2010 and December 2016 with ≥16 years age at the time of diagnosis of autoimmune hepatitis. Data collection was done from the review of medical records. Statistical analysis was performed using SPSS version 20. RESULTS: The study included 278 patients, 90% of the patients were women, the median age at diagnosis was 50 years. 37.8% were cirrhotic at the time of diagnosis. The biochemical remission was 85%. In patients who developed cirrhosis it was found a higher proportion of men (21.2 vs. 7.8%, p=.027), a greater frequency of overlap autoimmune-primary sclerosant cholangitis (6.0 vs. 0% p=.006) and a greater frequency of non-response to treatment (12.1 vs. 1.6%, p=.004). CONCLUSION: Autoimmune hepatitis is not a rare disease in Colombian population; it predominates in women but has a less favourable course in men. An important number of patients are cirrhotic at the time of diagnosis, the response to treatment and complications in our population are similar to those described worldwide.

[Epidemiología y desenlaces de la lesión renal aguda en Latinoamérica].

La lesión renal aguda (LRA) o injuria renal aguda, como se describe en Sudamérica, está sobreestimada por estudios epidemiológicos de países de alto nivel económico. En Latinoamérica (LA) existe un vacío de información sobre la epidemiología de la LRA. Se realizó una búsqueda de artículos publicados en LA referentes a la LRA y se hallaron 61 estudios, que representan a 10,670 pacientes latinoamericanos, en los cuales se distingue entre población adulta y pediátrica, LRA adquirida en la comunidad (LRA-AC) y adquirida en el hospital (LRA-AH), y se describen sus etiologías y desenlaces. El conocimiento de la incidencia y características de los pacientes con LRA en LA nos permitirá el desarrollo de estrategias preventivas y mejor acceso a un tratamiento de apoyo adecuado.Acute kidney injury (AKI) is over represented by epidemiological studies of high-income countries. In Latin America there is a lack of information on the epidemiology of AKI. We conducted a search of articles on AKI published in Latin America, finding 61 studies that represent 10,670 Latin American patients. Data were segmented by adult and pediatric populations, and community-acquired AKI and hospital-acquired AKI. Finally, etiology and outcomes are described. The knowledge of the incidence and characteristics of patients with AKI in Latin America will allow us to develop preventive strategies and better access to adequate support treatment.

An optimized clarithromycin-free 14-day triple therapy for Helicobacter pylori eradication achieves high cure rates in Uruguay.

BACKGROUND: Strong acid inhibition increases cure rates with triple therapy and 14-day are more effective than 7-day treatments. The combination of amoxicillin plus metronidazole at full doses has been shown to overcome metronidazole resistance and to achieve good eradication rates even in patients harboring resistant strains. No previous studies have been reported in Latin-America with this optimized triple-therapy scheme. AIMS: The aim of the present study was to assess the eradication rate and tolerance of a new first-line treatment regimen associating strong acid inhibition, amoxicillin and metronidazole. METHODS: Patients from the Clínica de Gastroenterología of the Hospital de Clínicas (Montevideo, Uruguay) were included. Hp status was mainly assessed by at least one of the following: histologyor urea breath test (UBT). A 14-day treatment was prescribed comprising esomeprazole 40mg twice a day plus amoxicillin 1g and metronidazole 500mg, both three times a day. H. pylori cure was assessed by UBT. RESULTS: Forty-one patients were enrolled. Mean age was 53.3±13 years and 17.1% of patients were male. Main indications for treatment were: functional dyspepsia (27.5%), gastritis (45%), gastric or duodenal erosions (20%), gastric ulcer (5%) and intestinal metaplasia (2.5%). H. pylori eradication was achieved in 33 of the 37 patients who returned for follow-up. Eradication rates were 80.5% (95% CI: 68.4-92.6) by intention-to-treat (ITT) analysis and 89.2% (95% CI; 79.2-99.2) per protocol (PP). No major side effects were reported; 26 patients (65.8%) complained of mild side effects (nausea, diarrhea and headache). CONCLUSIONS: Cure rates of this triple therapy including esomeprazole, amoxicillin and metronidazole were 81% per ITT and the treatment was well tolerated. These optimal results with a simple clarithromycin-free triple therapy are better than described for standard triple therapy but there is still room for improvement to reach the desired target of 90% per ITT.

Comparison of ixekizumab with etanercept or placebo in moderate-to-severe psoriasis: Subgroup analysis of Latin American patients in the phase 3 randomized UNCOVER-3 study.

BACKGROUND AND OBJECTIVES: Ixekizumab demonstrated greater efficacy than placebo and etanercept in UNCOVER-3. Subgroup analysis of Latin American patients was performed. We report 12-week and 60-week data. PATIENTS AND METHODS: Analysis included 102 Latin American patients randomized to receive placebo (n=14), etanercept 50mg twice weekly (n=30), or ixekizumab 160-mg starting dose followed by 80mg every 2 weeks (Q2W; n=29) or every 4 weeks (Q4W; n=29). At week 12, patients maintaining efficacy response and adequate overall safety were assigned, at the discretion of the investigator, to long-term extension with ixekizumab Q4W. RESULTS: At week 12, Psoriasis Area and Severity Index (PASI) 100 scores were 0%, 20.0% (p=0.075 vs placebo), 62.1% (p<0.001 vs placebo; p=0.001 vs etanercept), and 48.3% (p=0.002 vs placebo; p=0.023 vs etanercept) for placebo, etanercept, ixekizumab Q2W, and ixekizumab Q4W, respectively. Among patients who continued therapy up to week 60 (n=97), PASI 100 scores were 71.4%, 60.0%, 77.8%, and 57.7% for patients who received induction placebo, etanercept, ixekizumab Q2W, and ixekizumab Q4W, respectively (non-responder imputation). By week 60, ≥1 serious adverse event was experienced by 7.1% (n=1/14), 3.3% (n=1/30), 14.8% (n=4/27), and 0% (n=0/26) of patients who received induction placebo, etanercept, ixekizumab Q2W, and ixekizumab Q4W, respectively. There were no cases of active tuberculosis with ixekizumab treatment through 60 weeks. CONCLUSIONS: In Latin American patients, both ixekizumab dosing regimens demonstrated greater efficacy than etanercept for treating psoriasis over 12 weeks. The safety profile of ixekizumab through 60 weeks was well tolerated and consistent with the overall profile.

Association of Psoriasis and Metabolic Syndrome in Latin America: A Systematic Review and Meta-Analysis. / Relación entre psoriasis y síndrome metabólico en Latinoamérica. Revisión sistemática y metaanálisis.

INTRODUCTION: Meta-analyses have found evidence of a relationship between psoriasis and metabolic syndrome, but Latin American populations have not been included. METHODOLOGY: We performed a systematic review and meta-analysis of observational studies including adults with psoriasis and metabolic syndrome indexed in Medline, Scopus, SciELO, Google Scholar, Science Direct, and LILACS between 1980 and 2016. We computed pooled odds ratios (OR) with a random effects model and analyzed subgroups according to patient variables used in the studies. RESULTS: Five studies with a total of 241 patients with psoriasis were found; 46.5% of the patients also had metabolic syndrome (pooled OR, 2.63; 95% CI: 1.11-6.23; P=.03). In studies using the Adult Treatment Panel III (ATP-III) criteria for metabolic syndrome, the pooled OR was similar at 3.97 (95% CI: 1.27-21.42). Studies that included patients with chronic and severe disease detected higher risk for metabolic syndrome (pooled OR, 6.65; 95% CI: 3.32-13.31). Limitations are that few studies have been done in Latin America, heterogeneity was high, and inconsistency was found across studies. CONCLUSION: The association between psoriasis and metabolic syndrome is high in Latin America. The association is stronger when psoriasis is chronic and severe and when the ATP-III criteria are used for diagnosis.

Increase in Mexican and Latin American scientific articles on irritable bowel syndrome.

BACKGROUND: There is an implied perception that little scientific information on irritable bowel syndrome (IBS) comes out of Mexico and Latin America in the international medical literature, but the number and tendencies of articles from the region on IBS are not known. AIMS: To determine the number and type of Mexican and Latin American articles on IBS published between 1990-2015. METHODS: A systematic search of Medline was carried out employing the terms « Irritable Bowel Syndrome ¼ or its abbreviation (IBS). Mexico and every other Latin American country were added to specify the search. The articles were selected if they were published in Mexico and/or the rest of Latin America, if they were international papers on IBS in the region, or if they were written by Mexican and/or Latin American authors. In addition, the articles were classified into the following categories: Reviews/Editorials/Letters to the Editor (REV/ED), Epidemiology/Quality of Life/Psychosocial Factors (EPI/QOL), Diagnostic (DX), Treatment (TX), and Translational/Pathophysiologic (TRANS) studies. RESULTS: A total of 66 articles from Mexico and 47 from Latin America were identified, but only 87.7 and 48.9%, respectively, fit the selection criteria. Category distribution was: EPI/QOL: 36.2%, REV/ED: 27.5%, TRANS: 18.8, TX: 10%, and DX: 7.5% and was similar between Mexico and Latin America (p=0.33). The year 2005 saw an increase in the number of articles in Mexico, with a peak in 2010. The figures for Latin American articles remained stable over the years, with a peak in 2012. CONCLUSIONS: A noticeable increase has been observed over the last decade in the research conducted on IBS in Mexico and Latin America. Even though the EPI/QOL studies predominate, the sophistication of research is reflected in the TRANS studies that are in third place of frequency. The information referred to herein demonstrates maturity in the field, making it possible to carry out consensuses based on local data.

Improving environmental and social targeting through adaptive management in Mexico's payments for hydrological services program.

Natural resource managers are often expected to achieve both environmental protection and economic development even when there are fundamental trade-offs between these goals. Adaptive management provides a theoretical structure for program administrators to balance social priorities in the presence of trade-offs and to improve conservation targeting. We used the case of Mexico's federal Payments for Hydrological Services program (PSAH) to illustrate the importance of adaptive management for improving program targeting. We documented adaptive elements of PSAH and corresponding changes in program eligibility and selection criteria. To evaluate whether these changes resulted in enrollment of lands of high environmental and social priority, we compared the environmental and social characteristics of the areas enrolled in the program with the characteristics of all forested areas in Mexico, all areas eligible for the program, and all areas submitted for application to the program. The program successfully enrolled areas of both high ecological and social priority, and over time, adaptive changes in the program's criteria for eligibility and selection led to increased enrollment of land scoring high on both dimensions. Three factors facilitated adaptive management in Mexico and are likely to be generally important for conservation managers: a supportive political environment, including financial backing and encouragement to experiment from the federal government; availability of relatively good social and environmental data; and active participation in the review process by stakeholders and outside evaluators.

Improving conservation outcomes with insights from local experts and bureaucracies.

We describe conservation built on local expertise such that it constitutes a hybrid form of traditional and bureaucratic knowledge. Researchers regularly ask how local knowledge might be applied to programs linked to protected areas. By examining the production of conservation knowledge in southern Mexico, we assert local expertise is already central to conservation. However, bureaucratic norms and social identity differences between lay experts and conservation practitioners prevent the public valuing of traditional knowledge. We make this point by contrasting 2 examples. The first is a master's thesis survey of local experts regarding the biology of the King Vulture (Sarcoramphus papa) in which data collection took place in communities adjacent to the Calakmul Biosphere Reserve. The second is a workshop sponsored by the same reserve that instructed farmers on how to monitor endangered species, including the King Vulture. In both examples, conservation knowledge would not have existed without traditional knowledge. In both examples, this traditional knowledge is absent from scientific reporting. On the basis of these findings, we suggest conservation outcomes may be improved by recognizing the knowledge contributions local experts already make to conservation programming.

[Implementation and evaluation of a blended learning course on gastroesophageal reflux disease for physicians in Latin America]. / Implementación y evaluación de un curso semipresencial sobre enfermedad por reflujo gastroesofágico para médicos de América Latina.

Integrating evidence-based clinical practice guidelines on gastroesophageal reflux disease into medical practice is of prime importance in Latin America, given its high prevalence in this region. The aim of this project was to implement and assess an educational intervention on gastroesophageal reflux disease, aimed at primary care physicians in Latin America, with contents based on current clinical guidelines. The course included initial activities, whether face-to-face or through distance learning, and a 2-month period of Internet study and interaction. A pilot test was carried out in Uruguay, which was then repeated in 5 countries (Mexico, Colombia, Venezuela, Argentina and again in Uruguay). A global template was designed, which was then adapted to each of the countries: this was done with the participation of local institutions and leaders. Local credits were given for recertification. Participation was free. Of 3,110 physicians invited to participate, 1,143 (36.8%) started the course. Of these, 587 (51.4%) accessed at least half the contents of the course and 785 (68.7%) took part in the clinical discussions. A total of 338 (29.6%) completed all the requirements of the course and received a certificate. Among physicians who took both the pre- and post-intervention knowledge tests, scores improved from 60 to 80% (P<.001). Ninety-two percent of planned changes in clinical practice were related to the pedagogic aims of the course. In conclusion, a multifaceted, 2-phase continuing education course was successfully imparted in Latin America, with an overall design that was adapted to each country. Determination of specific needs and the participation of national experts were fundamental to the success of the course.

Metabolic disorders across the body mass index spectrum in a Colombian population with nonalcoholic fatty liver disease.

BACKGROUND AND AIMS: The relationship between obesity and nonalcoholic fatty liver disease (NAFLD) has long been established, and the prevalence of both conditions has grown together. Recent interest in NAFLD in nonobese individuals has led to an increasing number of studies, especially in Asia. Despite the fact that the prevalence of NAFLD in Latin America is one of the highest in the world, there is a lack of information on lean NAFLD populations from the region. The aim of the present study was to assess the risk of metabolic comorbidities across the whole body mass index spectrum when nonalcoholic steatohepatitis (NASH) was first diagnosed in a Latin American population. METHODS: A single-center, cross-sectional study on Colombian patients newly diagnosed with NAFLD, within the time frame of 2010-2020, compared their metabolic biochemical profile, liver enzymes, risk of prevalent metabolic abnormalities, and liver disease. RESULTS: Data from 300 patients were collected. Ninety-two percent of the patients were men and the median patient age was 47 (IQR 20) years. We found no significant differences in the biochemical, metabolic profile, or liver enzyme plasma concentration between lean, overweight, and obese individuals. Obese patients had significantly higher LDL cholesterol, and a higher risk of dyslipidemia (OR 1.86, 95% CI 1.14-3.05). Every 1kg increase in body weight increased the risk of having NASH by 2% (95% CI 2-4). CONCLUSIONS: We evaluated the metabolic risk across the entire body mass index spectrum in a Colombian cohort with NAFLD and presented the characteristics of what we believe is the first Latin American lean NAFLD population to be described.

Local understandings of conservation in southeastern Mexico and their implications for community-based conservation as an alternative paradigm.

Since the 1990s national and international programs have aimed to legitimize local conservation initiatives that might provide an alternative to the formal systems of state-managed or otherwise externally driven protected areas. We used discourse analysis (130 semistructured interviews with key informants) and descriptive statistics (679 surveys) to compare local perceptions of and experiences with state-driven versus community-driven conservation initiatives. We conducted our research in 6 communities in southeastern Mexico. Formalization of local conservation initiatives did not seem to be based on local knowledge and practices. Although interviewees thought community-based initiatives generated less conflict than state-managed conservation initiatives, the community-based initiatives conformed to the biodiversity conservation paradigm that emphasizes restricted use of and access to resources. This restrictive approach to community-based conservation in Mexico, promoted through state and international conservation organizations, increased the area of protected land and had local support but was not built on locally relevant and multifunctional landscapes, a model that community-based conservation is assumed to advance.

Impact of COVID-19 pandemic on cardiometabolic patients without SARS-CoV-2 infection in Latin America.

BACKGROUND AND OBJECTIVES: A cross-sectional survey including 38 questions about demography, clinical condition, changes in health habits, and medical treatments for cardiometabolic patients in outpatient follow-up was conducted. From June 15 to July 15, 2020, a total of 13 Latin-American countries participated in enrolling patients. METHODS: These countries were divided into 3 geographic regions: Region 1 including North, Central, and Caribbean Regions (NCCR), Region 2 including the Andean Region (AR), and Region 3 including the Southern Cone Region (SCR). 4.216 patients were analyzed, resulting in a coefficient of 33.82%, 32.23%, and 33.94% for NCCR, AR, and SCR, respectively. RESULTS: Significant differences were found between the AR, SCR, and NCCR regions. The analysis of habitual medication usage showed that discontinued use of medication was more present in AR, reaching almost 30% (p < 0.001). The main finding of this study was the negative impact that restrictive measures have on adherence to medications and physical activity: Rs = 0.84 (p = 0.0003) and Rs = 0.61 (p = 0.0032), respectively. AR was the most vulnerable region. CONCLUSION: Restrictive quarantine measures imposed by the different countries showed a positive correlation with medication discontinuation and a negative correlation with physical activity levels in patients analyzed. These findings characterize the impact of the consequences left by this pandemic. Undoubtedly, restrictive measures have been and will continue to have reverberating negative effects in most Latin-American countries.

ANTECEDENTES Y OBJETIVOS: Se realizó una encuesta transversal que incluyó 38 preguntas sobre demografía, estado clínico, cambio de hábitos de salud, tratamientos médicos a pacientes cardiometabólicos en seguimiento ambulatorio. Un total de 13 países latinoamericanos inscribieron pacientes del 15 de junio al 15 de julio de 2020. MÉTODO: Los países se dividieron en 3 regiones geográficas Región 1 (NCCR): Región Norte, Centro y Caribe; Región 2 (AR): Región Andina; Región 3 (SCR): Región Cono Sur. Las medidas de aislamiento se estimaron a partir de informes nacionales y se correlacionaron utilizando el coeficiente R de Spearman. Se analizaron 4.216 pacientes, NCCR (33.82%); AR (32.23%) SCR (33.94%). RESULTADOS: Se encontraron diferencias significativas entre regiones. Este análisis de la medicación habitual mostró que la discontinuación de la medicación fue mayor en RA, llegando a casi el 30% (p < 0.001). El principal hallazgo de este estudio fue el impacto negativo que tienen las medidas restrictivas sobre la adherencia a la medicación y la actividad física, Rs = 0.84 (p = 0.0003) y Rs = 0.61 (p = 0.0032), respectivamente. Se encontraron diferencias significativas entre regiones. AR es la región más vulnerable. CONCLUSIONES: Las medidas restrictivas impuestas por los diferentes países (cuarentena) mostraron una correlación positiva con la interrupción de la medicación y una correlación negativa con la cantidad de actividad física. El impacto de las consecuencias que deja esta pandemia será muy profundo en la mayoría de los países latinoamericanos.

Consensus on complementary feeding from the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition: COCO 2023.

Complementary feeding (CF) is defined as the feeding of infants that complements breastfeeding, or alternatively, feeding with a breast milk substitute, and is a process that is more than simply a guide as to what and how to introduce foods. The information provided by healthcare professionals must be up-to-date and evidence-based. Most of the recommendations that appear in the different international guidelines and position papers are widely applicable, but some must be regionalized or adapted to fit the conditions and reality of each geographic zone. The Nutrition Working Group of the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition (LASPGHAN) summoned a group of experts from each of the society's member countries, to develop a consensus on CF, incorporating, whenever possible, local information adapted to the reality of the region. The aim of the present document is to show the results of that endeavor. Utilizing the Delphi method, a total of 34 statements on relevant aspects of CF were evaluated, discussed, and voted upon.

Patient-reported outcomes in RA patients treated with tofacitinib or bDMARDs in real-life conditions in two Latin American countries.

OBJECTIVE: To describe efficacy, safety, and patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA) with an inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) treated with tofacitinib or biological DMARDs (bDMARDs) in real-life conditions. METHODS: A noninterventional study was performed between March 2017 and September 2019 at 13 sites in Colombia and Peru. Outcomes measured at baseline and at the 6-month follow-up were disease activity (RAPID3 [Routine Assessment of Patients Index Data] score), functional status (HAQ-DI [Health Assessment Questionnaire] score), and quality of life (EQ-5D-3L [EuroQol Questionnaire]). The Disease Activity Score-28 (DAS28-ESR) and frequency of adverse events (AEs) were also reported. Unadjusted and adjusted differences from baseline were estimated and expressed as the least squares mean difference (LSMD). RESULTS: Data from 100 patients treated with tofacitinib and 70 patients with bDMARDs were collected. At baseline, the patients' mean age was 53.53 years (SD 13.77), the mean disease duration was 6.31 years (SD 7.01). The change from baseline at month 6 was not statistically significant different in the adjusted LSMD [SD] for tofacitinib vs. bDMARDs for RAPID3 score (-2.55[.30] vs. -2.52[.26]), HAQ-DI score (-.56[.07] vs. -.50[.08]), EQ-5D-3L score (.39[.04] vs. .37[.04]) and DAS28-ESR (-2.37[.22] vs. -2.77[.20]). Patients from both groups presented similar proportions of nonserious and serious AEs. No deaths were reported. CONCLUSION: Changes from baseline were not statistically significantly different between tofacitinib and bDMARDs in terms of RAPID3 scores and secondary outcomes. Patients from both groups presented similar proportions of nonserious and serious AEs. CLINICAL TRIAL NUMBER: NCT03073109.

Hispano-American Brain Bank on Neurodevelopmental Disorders: An initiative to promote brain banking, research, education, and outreach in the field of neurodevelopmental disorders.

Neurodevelopmental disorders (NDDs) are conditions that present with brain dysfunction due to alterations in the processes of brain development. They present with neuropsychiatric, cognitive, and motor symptoms. Autism spectrum disorder (ASD) and Fragile X syndrome (FXS) are two of the most common NDDs. Human brain tissue is a scarce resource that is obtained from postmortem donations. In the case of NDDs, specifically autism, the reduced donation rate of brains prevents researchers to investigate its pathology and fine anatomy. The Hispano-American Brain Bank of Neurodevelopmental Disorders (Banco Hispanoamericano de CErebros de trastornos del NEurodesarrollo) or CENE is a large-scale brain bank for neurodevelopmental disorders in Hispano-America and the US. CENE's objectives are to collect and distribute brains of patients with NDDS, with a focus on ASD and FXS, to perform research, promote education of future scientists, and enhance public awareness about the importance of human tissue availability for scientific research on brain function and disease. CENE has thus far established a bilingual system of nodes and teams in several American countries including California-US, Pennsylvania-US, México, Puerto Rico, Colombia, and Dominican Republic. CENE ensures that postmortem NDD samples used in research better match the world's genetic and ethnic diversity. CENE enables and expands NDD brain research worldwide, particularly with respect to ASD and FXS.

Meta-analysis of gender inequities in cataract surgical coverage in Latin America.

OBJECTIVE: To perform an updated meta-analysis of cataract surgical coverage (CSC) data in Latin American studies to confirm that gender equity exists in terms of receiving cataract surgery. MATERIALS AND METHODS: A literature search of Rapid Assessment of Avoidable Blindness (RAAB) studies in Latin American published since 2011 was done. Older studies from countries that did not have newer data published were also included. Using summary original study data of CSC rates on an individual basis, a random effects model of meta-analysis was performed to evaluate the differences in CSC between men and women. RESULTS: Nineteen studies from 17 countries were included (Mexico data were pooled). The odds ratios at a visual acuity (VA) of <3/60 and <6/18 were 1.04 [95% confidence interval (CI): 0.82-1.32] and 1.04 (95% CI: 0.90-1.19), respectively, without heterogeneity. There were no significant gender differences for CSC at any VA level. CONCLUSIONS: This updated meta-analysis of CSC data from Latin American countries supports that gender inequity in terms of receiving cataract surgery is not an issue in the region. The results do not provide insight into gender inequity in terms of the quality of cataract surgery and other types of eye care services.

OBJETIVO: Realizar un metaanálisis actualizado de la cobertura de cirugía de catarata en estudios latinoamericanos para confirmar que existe equidad de género en términos del acceso a cirugía de catarata. MATERIAL Y MÉTODOS: Se realizó una búsqueda de la literatura de "Rapid Assessments of Avoidable Blindness (Encuestas Rápida de Ceguera Evitable)" publicados en Latinoamérica desde el 2011. Se incluyeron también estudios anteriores de países que no tenían publicados datos más recientes. Utilizando el compendio de datos de los estudios originales de la cobertura de cirugía de catarata (Cataract Surgery Coverage, CSC por sus siglas en inglés) en base individual, se realizó un modelo de efectos aleatorios de metaanálisis para evaluar las diferencias en la CSC entre hombres y mujeres. RESULTADOS: Se incluyeron 19 estudios de 17 países (los datos de México fueron agrupados). La oportunidad relativa (razón de probabilidades) para una agudeza visual (AV) de <3/60 y <6/18 fueron de 1.04 [95% Intervalo de confianza (IC): 0.82-1.32] y 1.04 (95% IC: 0.90-1.19), respectivamente, sin heterogeneidad. No hubo diferencias significativas para la CSC a ningún nivel de AV. CONCLUSIONES: Este metaanálisis actualizado de la CSC de Latinoamérica, confirma que no existe inequidad de género en términos de acceso a cirugía de catarata en esta región.

E-1500: Survey on feeding practices in the first 1,500 days of life, recommended by healthcare professionals in Latin America.

INTRODUCTION: Health-disease processes are established and programmed in the first 1500 days of life, a period in which nutrition and the microbiota play a fundamental role. Feeding practices vary, according to regional sociocultural characteristics. The Early Nutrition Group of the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition (LASPGHAN) established the goal of identifying the main feeding practices in the first 1500 days that were recommended by health professionals in Latin America. MATERIALS AND METHODS: A survey was conducted on the aspects of maternal-infant and young child nutrition during the first 1500 days of life. An open invitation was extended to Latin American healthcare professionals to anonymously answer the online survey. RESULTS: A total of 1284 surveys from participants in 18 Latin American countries were analyzed. The mean age of the participants was 37.14 ±â€¯11.1 years, 75.7% were women, 64.7% were physicians, and the rest were nutritionists/nutriologists. A total of 71.4% were familiar with the concept of the first 1000 days of life, 95% answered that exclusive breastfeeding should be carried out up to 6 months of age, and 34.3% responded that complementary feeding should be begun between 4 and 6 months of age. There was scant knowledge regarding nutrition in the pregnant woman. Adherence to traditional complementary feeding practices was evident. CONCLUSIONS: In a group of Latin American healthcare professionals, knowledge about nutrition in the first 1000-1500 days of life of an individual is still incomplete and insufficient, showing the need for continued training of healthcare professionals, with respect to those themes.

Consensus on the diagnosis and treatment of cow's milk protein allergy of the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition.

Cow's milk protein allergy (CMPA) is the most frequent cause of food allergy in the first months of life. Despite the fact that there are different guidelines and recommendations on the management of children with CMPA, there continues to be great variability in diagnostic and therapeutic criteria in Latin America. The Food Allergy Working Group of the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition summoned a group of Latin American experts to reach a consensus and formulate a document to unify diagnostic and therapeutic criteria for CMPA. Three teams were formed, each with a coordinator, and the members of each team developed a series of statements for their corresponding module: a) clinical manifestations and diagnosis; b) diagnostic tools, and c) treatment. A search of the medical literature was carried out to support the information presented in each module and 28 statements were then selected. The statements were discussed, after which they were evaluated by all the experts, utilizing the Delphi method. Their opinions on statement agreement or disagreement were anonymously issued. The final statements selected were those with above 75% agreement and their corresponding recommendations were formulated, resulting in the document presented herein.

Prevalence of osteoporosis in Colombia: Data from the National Health Registry from 2012 to 2018.

INTRODUCTION: Osteoporosis is considered a healthcare problem due to the increased risk of fractures and high cost of care. In Colombia, the Ministry of Health introduced SISPRO, a tool to collect nationwide information from the health system. The information collected from SISPRO is available for scientific analysis. This article presents an analysis of the prevalence and characteristics of patients with osteoporosis using data from 2012 to 2018. AIM: To estimate prevalence of osteoporosis between January 2012 to December 2018 and describe the patients' demographic characteristics. METHODS: This is a descriptive epidemiological study using the International Statistical Classification of Diseases and Related Health Problems related to osteoporosis as search terms using the SISPRO database. RESULTS: National records report 249,803 patients over 50 years old diagnosed with osteoporosis. The estimated prevalence is 2440 cases per 100,000 inhabitants over 50 years old (based on a total population of 10,236,132), being more frequent in women (92% of cases), with a female/male ratio of 12.3:1. CONCLUSION: This study shows a lower prevalence than previous estimates or projections. Given these findings we think it is necessary to act to promote health policies for patients with osteoporosis.
