Desigualdad en las prácticas de lactancia y alimentación complementaria en la Argentina, según nivel de ingresos del hogar en 2018-19 / Inequality in breastfeeding and complementary feeding practices in Argentina by household income level in 2018­2019

Introducción. La calidad de la alimentación es un derecho vinculado con la supervivencia, el crecimiento saludable, la prevención de enfermedades crónicas y malnutrición en todas sus formas. El objetivo de este trabajo fue analizar las prácticas de lactancia y de alimentación de menores de 2 años de áreas urbanas de la Argentina en 2018-19, según el nivel de ingreso de los hogares. Población y métodos. Estudio secundario con datos de la 2da. Encuesta Nacional de Nutrición y Salud 2018-19. Se analizaron indicadores de lactancia y alimentación complementaria, según metodología de la Organización Mundial de la Salud (OMS) y Unicef. Se estratificó según nivel de ingresos del hogar. Resultados. El análisis incluyó 5763 menores de 24 meses. Aunque el 97 % fue alguna vez amamantado, solo el 47 % de los menores de 6 meses tuvo lactancia exclusiva el día previo y el 48 % mantenía la lactancia luego del año, con mayor prevalencia en los niños/as de menores ingresos. En el día previo, el 23 % de los niños/as de 6 a 23 meses no consumió ninguna verdura o fruta; el 60 % consumió alimentos no saludables y el 50 %, bebidas dulces. Las bebidas dulces y la ausencia de frutas y verduras fueron mayores en aquellos de hogares de menores ingresos. Conclusión. La calidad de la alimentación de los niños/as dista de las recomendaciones y está condicionada por los ingresos. En los sectores empobrecidos, es menor el inicio temprano de la lactancia, la diversidad alimentaria mínima y el consumo de frutas y verduras, y es mayor el consumo de bebidas dulces.

Introduction. Diet quality is a right related to survival, healthy growth, prevention of chronic diseases, and malnutrition in all its forms. The objective of this study was to analyze breastfeeding and feeding practices in children younger than 2 years from urban areas of Argentina in 2018­2019 according to their household income level. Population and methods. Secondary analysis of data of the Second National Survey on Nutrition and Health (ENNyS2) of 2018­2019. Breastfeeding and complementary feeding indicators proposed by the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) were analized. Data were stratified by household income level. Results. The analysis included 5763 children younger than 24 months old. Although 97% was ever breastfed, only 47% of infants younger than 6 months were exclusively breastfed the previous day and 48% continued with breastfeeding after 1 year old, with a higher prevalence in low-income children. The previous day, 23% of children aged 6 to 23 months did not eat any fruit or vegetable, 60% consumed unhealthy foods, and 50% consumed sweet beverages. The consumption of sweet beverages and the absence of fruit and vegetables were higher in low-income households. Conclusion. The quality of children's diet is far from the recommendations and is conditioned by income. Early initiation of breastfeeding, minimum dietary diversity, fruit and vegetable consumption are lower and sweet beverage consumption is greater in impoverished sectors.

Cost-Effectiveness of 20-Valent Pneumococcal Conjugate Vaccine in Argentinean Adults.

INTRODUCTION: In Argentina, vaccination with 13-valent pneumococcal conjugate vaccine (PCV13) followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23; PCV13 → PPSV23) has been recommended for all adults aged ≥ 65 years and younger adults with chronic medical ("moderate-risk") or immunocompromising ("high-risk") conditions since 2017. With the approval of a 20-valent PCV (PCV20), we evaluated the cost-effectiveness of PCV20 versus current recommendations for moderate-/high-risk adults aged 18-64 years and all adults 65-99 years. METHODS: A probabilistic cohort model was used to project lifetime outcomes and costs associated with invasive pneumococcal disease (IPD) and all-cause non-bacteremic pneumonia (NBP), and the expected impact of vaccination. Clinical outcomes were projected annually based on Argentinean data. Economic costs were estimated based on cases and corresponding medical costs (adjusted to 2023 USD) and costs of vaccine and administration. Cost-effectiveness of PCV20 was evaluated versus the current strategy, PCV13 → PPSV23, and alternatively, versus sequentially administered 15-valent PCV and PPSV23 (PCV15 → PPSV23), and presented as cost per quality-adjusted life year gained; a healthcare system perspective was used. Costs and benefits were discounted at 3%/year. RESULTS: PCV20 in lieu of PCV13 → PPSV23 among moderate-/high-risk adults aged 18-64 years and all adults 65-99 years (N = 13.4M) prevented 3838 IPD, 4377 inpatient NBP, and 6003 outpatient NBP cases, and 1865 disease-related deaths; relative to PCV15 → PPSV23 the corresponding reductions were 2775, 3285, 4518, and 1348. PCV20 was projected to be the dominant strategy versus PCV13 → PPSV23 and PCV15 → PPSV23 as overall costs were lower by $87.6M and $80.8M, respectively. In probabilistic sensitivity analyses, PCV20 was dominant (i.e., more effective, less costly) in 100% of 1000 simulations. CONCLUSIONS: Analyses suggest implementing a PCV20 vaccination program in moderate-/high-risk adults aged 18-64 years and all adults ≥ 65 years-in lieu of PCV13 → PPSV23-would yield substantial reductions in pneumococcal disease and would be cost saving to the Argentinean healthcare system.

Pneumococcal pneumonia has a high disease burden in both children and adults. Older adults and those with certain underlying conditions are more susceptible to severe pneumococcal disease resulting in considerable economic burden on the healthcare system. In Argentina, vaccination with 13-valent pneumococcal conjugate vaccine (PCV13) followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23) a year later is recommended for all adults aged ≥ 65 years and adults aged 18­64 years with underlying risk conditions. Despite vaccination efforts, prevalence of pneumococcal disease remains high. Two higher-valent PCVs­15-valent PCV (PCV15) and 20-valent PCV (PCV20)­are available for use in adults with PCV20 offering additional serotype coverage. This study assessed the cost-effectiveness of replacing current (PCV13 → PPSV23) and alternative (PCV15 → PPSV23) vaccination strategies with PCV20 alone. The use of PCV20 was evaluated among Argentinean adults aged 18­64 years with underlying risk conditions and all adults aged 65­99 years (N = 13 million). Over a lifetime time horizon, compared to PCV13 → PPSV23, PCV20 use would avert 14,218 cases and 1865 deaths, and increase quality-adjusted life years by 8655. Compared to PCV15 → PPSV23, PCV20 reduced cases and deaths by 10,578 and 1348, respectively, and increased quality-adjusted life years by 6341. In both comparisons, PCV20 use was cost saving with $87.6 million and $80.8 million lower costs compared to PCV13 → PPSV23 and PCV15 → PPSV23, respectively. Results of the cost-effectiveness analyses suggest that the use of PCV20 is a cost-saving strategy, reducing overall costs to the healthcare system and improving public health.

Lung cancer in Argentina: a modelling study of disease and economic burden.

OBJECTIVES: Lung cancer remains a significant global public health challenge and is still one of the leading causes of cancer-related death in Argentina. This study aims to assess the disease and economic burden of lung cancer in the country. STUDY DESIGN: Burden of disease study. METHODS: A mathematical model was developed to estimate the disease burden and direct medical cost attributable to lung cancer. Epidemiological parameters were obtained from local statistics, the Global Cancer Observatory, the Global Burden of Disease databases, and a literature review. Direct medical costs were estimated through micro-costing. Costs were expressed in US dollars (US$), April 2023 (1 US$ = 216.38 Argentine pesos). A second-order Monte Carlo simulation was performed to estimate the uncertainty. RESULTS: Considering approximately 10,000 deaths, 12,000 incident cases, and 14,000 5-year prevalent cases, the economic burden of lung cancer in Argentina in 2023 was estimated to be US$ 556.20 million (396.96-718.20), approximately 1.4% of the total healthcare expenditure for the country. The cost increased with a higher stage of the disease, and the main driver was drug acquisition (80%). A total of 179,046 disability-adjusted life years could be attributable to lung cancer, representing 10% of the total cancer. CONCLUSION: The disease and economic burden of lung cancer in Argentina implies a high cost for the health system and would represent 19% of the previously estimated economic burden for 29 cancers in Argentina.

A devastating blow: personal reflections on Argentina's scientific decline.

As an Argentine scientist, the defunding of CONICET and INTA feels like a blow to progress and our future. Despite free education, these cuts force talented researchers to seek opportunities abroad. Argentina's history of scientific achievement, from Nobel Prizes to COVID-19 vaccines, is at risk. Defunding science weakens our ability to solve problems and compete globally.

Pediatric COVID-19 in Argentina: a comprehensive analysis of disease and economic burden through official data and a systematic literature review.

Background: Limited data are available on the clinical impact and economic burden of COVID-19 in the pediatric population in Argentina. We aimed to estimate the disease and economic burden of COVID-19 on children and adolescents. Methods: We analyzed official national databases and conducted a supplemental systematic review of the published literature with meta-analysis in children aged 0-18. The period of interest was from March 2020 to August 2021, before the introduction of vaccination in this age group as a national strategic plan. In addition, we used a cost of illness analysis to estimate the direct medical costs associated with COVID-19. All costs are reported in US dollars 2023. Results: A total of 450,503 confirmed COVID-19 cases and 180 multisystem inflammatory syndrome (MIS-C) were reported in Argentina in the study period. Fourteen observational clinical studies were identified. The meta-analyses of severity level from hospital patients showed that according to different studies 15%-28% of cases were asymptomatic, 68%-88% were mild or moderate, and 3%-10% were severe or critical. About 28% of children had an underlying disease. In addition, the estimated economic burden associated with COVID-19 was 80 million dollars and 4 million dollars corresponded to MISC. Conclusion: Significant impact of COVID-19 on the healthcare system and substantial economic implications for the pediatric population in Argentina were identified. The findings should help policymakers to make informed decisions and allocate resources effectively.

Burden of treatment and quality of life in relapsing remitting multiple sclerosis patients under early high efficacy therapy in Argentina: Data from the Argentinean registry.

The objective of this study was to describe and compare the burden of treatment (BOT) and the quality of life (QoL) in early high efficacy therapy (HET) vs. escalation therapy in relapsing remitting multiple sclerosis (RRMS) patients included in RelevarEM, the Argentinean registry of MS (RelevarEM, NCT 03,375,177). METHODS: cross sectional study conducted between September and December 2022. Participating patients were adults, RRMS patients who initiated (during the last three years) their treatment with a HET (natalizumab, ocrelizumab, alemtuzumab, cladribine) or with escalation treatment (beta interferon, glatiramer acetate, teriflunomide, dimethyl fumarate or fingolimod). Clinical and demographic aspect were collected. QoL and BOT was measured with the validated to Spanish MusiQol and BOT questionnaire. Propensity score (PS)-based nearest-neighbor matching was applied to homogenize groups. Comparisons were be done using a linear regression analysis model stratified by matched pairs, with BOT and QoL assessments as main outcomes. RESULTS: 269 patients were included in the analysis, mean age 33.7 ± 5.7 years, 193 (71.7 %) were female. A total of 136 patients were on early HET while 133 were on escalation therapy. In the entire group the mean total BOT score (±SD) was 48.5 ± 15.3 while in the group of patients receiving early HET we observed that the mean BOT score (±SD) was 43.5 ± 12.2 vs. 54.3 ± 13.3 in escalation treatment (p < 0.0001). Regarding the score QoL (±SD), in the entire sample we observed a global score of 77.4 ± 11.2. When we stratified groups, in HET (±SD) it was 81.3 ± 14 vs. 74.1 ± 18.3 in escalation therapy (p = 0.0003). CONCLUSION: in this multicenter study that included 269 patients from Argentina we observed in early HET a significantly lower BOT and higher QoL than patients receiving escalation therapy.

Por primera vez, se elaboraron tablas de referencia de CF en escolares sanluiseños

Introduction. The assessment of physical fitness (PF), is useful strategy to know the current status of schoolchildren. Our primary objective was to measure the current health status and PF levels of schoolchildren in San Luis and to develop PF reference tables. Population and methods. Schoolchildren aged 9 to 12 years (boys and girls) were assessed based on 2 health indicators: body mass index and blood pressure. PF was measured using the ALPHA-Fitness test battery. Blood pressure, body mass, height, foot and hand length, standing long jump, 30 m sprint, 4 × 10 m agility test, and 20 m shuttle run test were assessed. The body mass index (BMI) and biological maturation were estimated. Results. A total of 15 548 schoolchildren were assessed. Average systolic blood pressure was 101 ± 10 mmHg and diastolic blood pressure, 66 ± 7 mmHg; BMI: 20.2 ± 4.3 kg/m2. Average PF was, in the cardiorespiratory component, VO2 max.: 39.87 ± 3.2 mL/kg/min and speed reached during the 20 m shuttle run test: 8.9 ± 0.6 km/h; in the musculoskeletal component, standing long jump: 120.6 ± 23.9 cm, 30 m sprint: 6.56 ± 0.85 s, 4 × 10 m agility test: 15.17 ± 1.82 s. The performance was better in the boys group (p < 0.001). Conclusion. Blood pressure was normal. Fifty percent of the sample was overweight or obese as per their BMI. Both boys and girls showed low PF levels. PF reference tables for schoolchildren from San Luis were developed for the first time.

Sex and Socioeconomic Disparities in Dementia Risk: A Population-Attributable Fraction Analysis in Argentina.

INTRODUCTION: Twelve modifiable risk factors (RFs) account for 40% of dementia cases worldwide. However, limited data exist on such factors in middle- and low-income countries. We aimed to estimate the population-attributable fractions (PAFs) for the 12 RFs in Argentina, assessing changes over a decade and exploring socioeconomic and sex influences. METHODS: We conducted cross-sectional analyses of the 12 RFs from Argentinian surveys conducted in 2009, 2015, and 2018, including 96,321 people. We calculated PAFs and stratified estimates based on sex and income. RESULTS: We estimated an overall PAF of 59.6% (95% CI = 58.9-60.3%). The largest PAFs were hypertension = 9.3% (8.7-9.9%), physical inactivity = 7.4% (6.8-8.2%), and obesity = 7.4% (6.8-7.9%). Men were more impacted by excessive alcohol, while women by isolation and smoking. Lower income linked to higher PAFs in education, hypertension, and obesity. DISCUSSION: Argentina has a higher PAF for dementia than the world population, with distinct RF distribution. PAF varied by sex and economic status, advocating tailored prevention strategies.

[Financial and health impact of two models of providing prostheses in a public health systemImpacto econômico e sanitário de dois modelos de fornecimento de próteses em um sistema público de saúde]. / Impacto sanitario económico de dos modelos de provisión de prótesis desde un sistema público de salud.

Objective: Compare the health outcomes and financial outcomes of two systems for the procurement of prostheses: the traditional system, in which procurement is initiated when a product is requested; and the "Prosthesis Bank" model, based on a current inventory of supplies. Methods: Descriptive-analytical study of users of Ministry of Health services in the province of Buenos Aires, Argentina. The patients belonged to two study groups: 1) prostheses were provided through the traditional computerized system for hospital procurement and contracting, known as SIPACH; and 2) prostheses were provided by the Prosthesis Bank. The study was limited to endovascular prostheses (coronary stents) and hip prostheses. Official government databases were used. The study period was from 01/01/2018 to 31/10/2022. The variables analyzed were: age, sex, diagnosis, hospital, type of implant or prosthesis, date of request, date received, unit price, direct and indirect costs, average cost of daily hospitalization, cost-effectiveness, and budgetary impact. Results: A total of 4 106 applications were analyzed. In the traditional system: 13.5% of patients did not get their prostheses; it took 50 days longer than with the Prosthesis Bank; and total costs were higher in SIPACH (coronary stent, +463%; hip prosthesis, +133%). The Prosthesis Bank saved USD 3.2 million annually and prevented 22 deaths through early provision of endovascular prostheses. Conclusions: The Prosthesis Bank proved to be superior to the traditional model for providing prostheses, both in terms of health-by achieving better access, shortening waiting times, and avoiding deaths-and financially-by significantly reducing unit and overall prices, achieving significant savings in allocated budgets.

Objetivo: Comparar os resultados econômicos e sanitários de dois sistemas de aquisição de próteses: um sistema tradicional, no qual a compra é iniciada mediante solicitação, e um modelo em estoque chamado Banco de Próteses (BDP). Métodos: Estudo descritivo-analítico com usuários do Ministério da Saúde da província de Buenos Aires, Argentina. Os pacientes pertenciam a dois grupos de estudo: 1) próteses fornecidas pelo método tradicional do Sistema Informatizado de Aquisição e Contratações Hospitalares (SIPACH); e 2) próteses fornecidas pelo BDP. A análise se restringiu a próteses endovasculares do tipo stent coronariano e próteses de quadril. Foram utilizados bases de dados oficiais do governo. O período do estudo foi de 01/01/2018 a 31/10/2022. As variáveis analisadas foram: idade, sexo, diagnóstico, hospital, tipo de implante ou prótese; data de solicitação; data de aquisição; preço unitário, custos diretos e indiretos; custo médio diário de internação, relação custo-efetividade e impacto orçamentário. Resultados: Foram analisadas 4 106 solicitações. No sistema tradicional, 13,5% dos pacientes não receberam as próteses e houve 50 dias a mais de espera do que pelo BDP. Além disso, os custos totais foram maiores no SIPACH (+463% no caso dos stents coronários e +133% para as próteses de quadril). O BDP economizou US$ 3,2 milhões ao ano e evitou 22 mortes com o fornecimento precoce de próteses endovasculares. Conclusões: O BDP demonstrou superioridade em relação ao modelo tradicional de fornecimento de próteses, tanto em termos sanitários, ao oferecer maior acesso, diminuir o tempo de espera e evitar mortes, quanto em termos econômicos, ao reduzir significativamente os preços unitários e totais, gerando economias significativas nos orçamentos alocados.

Parasite assemblages in volatile host stocks: inter- and intra-cohort variability restrict their value as biological tags for squid stock assessment.

The Argentine shortfin squid, Illex argentinus, inhabits in the southwest Atlantic; it is a semelparous species which grows rapidly along its 1 year lifespan. The identification of its stocks is critical for sustainable fishery exploitation. Parasites have been used as biological indicators in a lower number of studies dealing with squids, therefore a validation of this methodology is necessary. The intra- and inter-cohort variability of parasite assemblages in the summer-spawning stock of I. argentinus was analysed to assess their value as indicators of stock structure. Four squid samples from the continental shelf of central Patagonia, corresponding to 3 consecutive cohorts, were examined for metazoan parasites. Results evidenced heterogeneity in terms of parasite assemblage composition and structure, dominated by short-lived gastrointestinal parasites, with a strong influence of host size, but no effect of squid sex. These changes are related to their recent habitats and diets, which change with ontogeny and migrations, clouding any interpretation of patterns when samples spatially or temporally separated are compared. Many squid species share these characteristics; therefore, it is recommended that the use of parasites as biological tags should be restricted to simultaneous sampling, while size or age must be considered for deriving proper conclusions.

The right to legal, safe and free abortion in Argentina: obstacles and challenges to the policy in force, 18 months after its implementation (2021-2022). / El derecho al aborto legal, seguro y gratuito en Argentina: obstáculos y desafíos de la política en acto a 18 meses de su implementación (2021-2022).

In Argentina, in January 2021 the bill for the Voluntary Interruption of Pregnancy (Ley 27.2610) was approved, enabling voluntary abortion until week 14 and unreservedly in cases of rape or pregnancy-induced health risks. From a feminist approach to collective health, this bill poses enormous challenges regarding the implementation of sexual and reproductive rights policies within the healthcare system. This article addresses the processes of  political strategizing, healthcare organization and technical-administrative action regarding the policy in force. The aim is to explore the obstacles, differences and inequalities impacting the access to sexual health, and to examine the articulations of healthcare officials/personnel and sexual rights activists, in order to understand the relations between state intervention and practices/experiences. The methodological strategy is qualitative. The main techniques for data collection are documentary and policy instruments analyses.

En enero de 2021, en Argentina, entró en vigor la Ley 27.610 de Interrupción Voluntaria del Embarazo, que habilita el aborto voluntario hasta la semana 14 y sin plazos en caso de violación o riesgo de la salud de la mujer, la niña o la persona gestante. Desde una perspectiva feminista y de la salud colectiva, esta ley plantea grandes desafíos en los procesos de implementación de políticas de derechos sexuales y reproductivos en el sistema de salud. En este artículo buscamos atender a los procesos de formulación de la estrategia política, la organización de la atención y la acción técnico-administrativa de la política en acto, para explorar los obstáculos y desigualdades en el acceso a la ley. Asimismo, hacemos hincapié en las articulaciones entre el personal de la salud, funcionarios/as y activistas, para comprender las relaciones entre intervención estatal y prácticas/experiencias. La estrategia metodológica es de tipo cualitativa. Las principales técnicas de recolección de datos son el análisis documental y de instrumentos de políticas.

Tendencias de la mortalidad femenina por cáncer de mama en Argentina, 2005-2020 / Female breast cancer mortality trends in Argentina, 2005-2020

Introducción: El cáncer de mama es una causa de muerte evitable en las mujeres de hasta 74 años de edad. Sin embargo, es el cáncer más frecuente y la primera causa de muerte por tumores en esa población. Objetivo: Analizar las tendencias de la mortalidad por cáncer de mama en las mujeres de Argentina entre 2005 y 2020, considerando el grupo de edad y la región geográfica. Método: Estudio cuantitativo y descriptivo con perspectiva sociodemográfica. Se calcularon tasas específicas de mortalidad a partir de datos oficiales y se aplicaron modelos de regresión joinpoint para evaluar su tendencia temporal. Resultados: La tasa de mortalidad ajustada por cáncer de mama disminuyó significativamente (PPCA: −1,5%; IC95%: −1,3% a −0,7%); sin embargo, aumentó en las mujeres de 25 a 34 años (PPCA: 2,3%; IC95%: 1,4% a 3,2%). El descenso registrado se trasladó mayormente a las regiones Centro, Cuyo y Noroeste, mientras que las tasas de mortalidad de las regiones Noreste y Patagónica no variaron significativamente. Conclusiones: No obstante los progresos documentados, se evidencian desafíos para reducir la mortalidad por cáncer de mama en las poblaciones más jóvenes. Asimismo, persisten las desigualdades regionales, lo que destaca la importancia de adaptar las acciones a las necesidades del territorio.

Background: Breast cancer is a preventable cause of death among women up to 74 years of age. However, it is the most common cause of cancer death among this population. Objective: To analyze female breast cancer mortality trends in Argentina between 2005 and 2020, taking into account age groups and geographical regions. Method: Quantitative and descriptive study carried out from a socio-demographic perspective. Specific mortality rates were calculated based on official data, and joinpoint regression models were applied to evaluate time trends in mortality. Results: The adjusted mortality rate attributed to breast cancer decreased significantly (AAPC: −1,5%; CI95%: −1,3% to −0,7%); however, it increased among women aged 25-34 (AAPC: 2,3%; CI95%: 1,4% to 3,2%). Besides, the decreasing of mortality took place mainly in Central, Cuyo and Northwest regions meanwhile the mortality rates from Northeast and Patagonia regions didnt vary significantly. Conclusions: Although progress has been made, there are still some challenges regarding the reduction of breast cancer mortality in young women. In addition, regional disparities remain, highlighting the importance to adapt actions to territorial needs.

Age and socio-economic status affect dengue and COVID-19 incidence: spatio-temporal analysis of the 2020 syndemic in Buenos Aires City.

In early 2020, Argentina experienced the worst dengue outbreak in its history, concomitant with first-to-date increasing COVID-19 cases. Dengue epidemics in temperate Argentina have already been described as spatially heterogeneous; in the previous 2016 outbreak, transmission occurred 7.3 times more frequently in slums compared to the rest of Buenos Aires City (CABA). These informal settlements have deficient sanitary conditions, precarious housing and high incidence of social vulnerabilities. The purpose of this work was to study the spatio-temporal patterns of the 2020 dengue epidemic in CABA in relation to socio-economic living conditions of its inhabitants and its interaction with the onset of COVID-19. The study considered the period between Jan 1st and May 30th 2020. Dengue and COVID-19 databases were obtained from the National Health Surveillance System; each record was anonymized and geo-localized. The city was divided according to census tracts and grouped in four socio-economic strata: slums, high, mid and low residential. An aligned-rank transform ANOVA was performed to test for differences in the incidence of dengue and COVID-19, and age at death due to COVID-19, among socio-economic strata, four age categories and their interaction. The incidence by cluster was calculated with a distance matrix up to 600 m from the centroid. Spatial joint dengue and COVID-19 risk was estimated by multiplying the nominal risk for each disease, defined from 1 (low) to 5 (high) according to their quantiles. During the study period, 7,175 dengue cases were registered in CABA (incidence rate 23.3 cases per 10,000 inh), 29.2% of which occurred in slums. During the same period, 8,809 cases of COVID-19 were registered (28.6 cases per 10,000 inh); over half (51.4%) occurred in slums, where the median age of cases (29 years old) was lower than in residential areas (42 years old). The mean age of the deceased was 58 years old in slums compared to 79 years old outside. The percentage of deaths in patients under 60 years old was 56% in slums compared to 8% in the rest of the city. The incidence of both diseases was higher in slums than in residential areas for most age categories. Spatial patterns were heterogeneous: dengue presented higher incidence values in the southern sector of the city and the west, and low values in highly urbanized quarters, whereas COVID-19 presented higher values in the east, south, high populated areas and slums. The lowest joint risk clusters were located mainly in high residential areas, whereas high joint risk was observed mainly in the south, some western clusters, the historical part of the city and center north. The social epidemiological perspective of dengue and COVID-19 differed, given that socio environmental heterogeneity influenced the burden of both viruses in a different manner. Despite the overwhelming effect of the COVID-19 pandemic, health care towards other diseases, especially in territories with pre-existing vulnerabilities, should not be unattended.

Meningococcal burden of disease in Argentina: 10 years epidemiologic review.

Invasive meningococcal disease (IMD) is an uncommon but serious and potentially fatal condition, mainly affecting infants. In 2017, Argentina introduced a vaccination program against serogroups A, C, W and Y (MenACWY) for infants aged 3, 5 and 15 months and adolescents aged 11 years. The objective of this study was to review the burden of IMD in Argentina in 2010-2019. Data were obtained from national surveillance databases, and the study estimated IMD incidence, mortality, case-fatality rates, and serogroup distributions across age groups. A total of 1,972 IMD cases were reported in the study period, with the highest incidence in infants aged < 1 year. Incidence peaked in 2013 and subsequently declined. Mortality rates were 18 times higher in infants than in other age groups, reflecting the high impact of IMD in this age group. The case-fatality rate was 8.5% on average and increased with age. The proportion of notified cases with serogroup identification increased over the period, reaching 91% in 2019. The most common serogroups over the study period were serogroup B (48%) and serogroup W (42%), with an increase in B relative to W since 2015. In infants aged < 1 year, the proportion of serogroup B increased in recent years, reaching around 70% of characterized cases in 2018-2019. These results show the dynamism of IMD and indicate the importance of vaccination at an early age and offering protection against predominant serogroups. These data are valuable to support evidence-based decision-making in healthcare.

Disparities in regional obesity rates in argentina by socioeconomic status / Disparidades en prevalencia de obesidad por región y estatus socioeconómico en Argentina

Abstract Background : Obesity rates in Latin America are increasing overall and among people with low socio economic status (SES). Obesity and SES disparities can vary by region-a valuable indicator of local drivers. The objective of this study was to examine regional and SES differences in obesity in Argentina. Methods : We used data from Argentina's 4th Na tional Risk Factors Survey (n = 29226) 2018 and defined obesity as BMI ≥ 30. Low SES was defined as not fin ished high school or having a household income in the lowest two quintiles. Descriptive analysis stratified by sex compared obesity rates by SES, province, and re gion. Age-adjusted logistic regression models explored the association between obesity, socioeconomic status, and region. Results : Obesity rates varied more by SES among women (39% for low SES vs. 26% for middle/high SES; p < 0.001) than among men (33% low SES vs. 29% middle/ high SES; p = 0.027). The Patagonian region had the high est obesity prevalence for both men (36%) and women (37%). A gender-stratified age-adjusted analysis with region and SES showed that low SES (OR 1.72, 95% CI 1.45, 2.03) and the Patagonian region (OR 1.29, 95% CI 1.02, 1.62) were the only significant predictors for women. Conclusions : SES associated disparities in obesity in Argentina were pronounced for women but not men. Disparities were particularly high in Patagonia. Further research is needed to understand the drivers behind these SES, regional, and gender disparities.

Resumen Introducción : Las tasas de obesidad en América La tina están aumentando, tanto en la población general como entre las personas con bajo nivel socioeconómi co (NSE). Las disparidades en obesidad y NSE pueden variar ampliamente según la región, un indicador po tencialmente valioso de fenómenos causales locales. El objetivo de este estudio fue examinar las diferencias en la prevalencia de obesidad a nivel regional y según el NSE en Argentina. Métodos : Utilizamos datos de la 4ª Encuesta Nacio nal de Factores de Riesgo realizada en Argentina en 2018 (n = 29226). Definimos obesidad como índice de masa corporal ≥ 30, y bajo NSE como no haber termi nado la escuela secundaria o tener un ingreso familiar en los dos quintiles más bajos. El análisis descriptivo estratificado por sexo comparó la prevalencia de obe sidad por NSE, provincia y región. Además, utilizamos modelos de regresión logística ajustados por edad para explorar la asociación entre obesidad, nivel socioeconó mico y región, tanto globalmente como estratificando por sexo.367 Resultados : Las tasas de obesidad variaron más por NSE entre las mujeres (39% NSE bajo vs. 26% NSE medio/ alto; p < 0.001) que entre los hombres (33% NSE bajo vs. 29% NSE medio/alto; p = 0.027). La región patagónica tuvo la mayor prevalencia de obesidad tanto para hom bres (36%) como para mujeres (37%). Un análisis estra tificado por género, con región y NSE como covariables, mostró que el bajo NSE (OR 1.72, IC 95% 1.45, 2.03) y la región patagónica (OR 1.29, IC 95% 1.02, 1.62) fueron los únicos predictores significativos para las mujeres; nin guno se asoció significativamente con un mayor riesgo de obesidad para los hombres. Conclusiones : Las disparidades asociadas al NSE en la obesidad en Argentina fueron pronunciadas entre mujeres, pero no entre hombres. Las disparidades fueron particularmente altas en la Patagonia. Se necesita más estudios para comprender los factores detrás de estas disparidades de NSE, regionales y de género.

An assessment of qualitative and quantitative cannabinoids analysis in selected commercially available cannabis oils in Argentina.

In recent years, the therapeutic use of cannabis products, especially cannabis oils, has increased significantly, due to the pharmacological potential of their cannabinoids, for the treatment of conditions, such as pain management, cancer, and epilepsy. In Argentina, patients with medical prescriptions can access to cannabis oil, through self-cultivation, a third-person (grower or importer), or a civil organization authorized for that purpose. However, these products remain largely unregulated in Argentina, and information available regarding labeling accuracy, especially cannabidiol (CBD)/ Δ9-tetrahydrocannabinol (Δ9-THC) concentrations are inconsistent or nonexistent, nor long-term product stability, and lot to lot variability. Understanding these properties is fundamental if these products are to be used in patients with a determinate pathology. Therefore, we analyzed commercially available cannabis oils (n: 500) in Argentina for qualitative and quantitative cannabinoids content. In order to provide a detailed overview of their cannabinoids profiles, and determine Δ9-THC, CBD, and cannabinol (CBN) concentrations, samples were diluted and analyzed by gas chromatography- mass spectrometry (GC/MS). Most of the samples tested positive for cannabinoids (n: 469) with Δ9-THC and CBD as the predominant cannabinoids. Among products tested, only 29.8% (n: 149) gave specific CBD label claims, and testing indicated a CBD tested positive of 70.5% (n: 105). For products (n: 17) with a THC-free label claim, testing indicated 76.5% (n: 13) of Δ9-THC positive, and cannabinoids were not detected in four products. Δ9-THC concentrations ranged from 0.1 to 143.0 mg/mL, CBD concentrations from 0.1 to 125.3 mg/mL, and CBN concentrations from 0.04 to 60.10 mg/mL; CBN/ Δ9-THC ratios ranged from 0.0012 to 2.31, and CBD/ Δ9-THC ratios from 0.0008 to 178.87. Furthermore, the (Δ9-THC + CBN)/CBD ratio of most samples was greater than one. In summary, our results indicate that cannabis oil products show wide variability in cannabinoids content, purity, and labeling.
