ABSTRACT The resistance of a weed to a herbicide may be accompanied by an ecological disadvantage, which can hinder the establishment of resistant biotypes when the herbicide is not used. The aim of this study, therefore, was to evaluate the growth and phenology of two biotypes of Raphanus raphanistrum, one susceptible and the other resistant to ALS inhibitors. The research was carried out from August to December 2020, conducting two simultaneous experiments, with the susceptible and resistant biotypes grown as single crops or together with wheat. The parameters under evaluation were plant height, number of leaves, leaf area, shoot dry weight, growth rate, leaf area ratio, net assimilation rate, and phenology - determined using the BBCH scale. The results showed not only that development and growth in the sensitive biotype was greater compared to the resistant biotype, but also the precocity of the biotype. The only variable for which the resistant biotype was superior was root dry weight. Cross-resistance to ALS inhibitors resulted in a difference in the growth and phenology of the resistant biotype that should be better evaluated, as the populations present large genetic differences.

ABSTRACT The global reemergence of measles in 2018–2019 reinforces the relevance of high-coverage immunization to maintain the disease elimination. During an outbreak in the Sao Paulo State in 2019, several measles cases were reported in individuals who were adequately vaccinated according to the current immunization schedule recommends. This study aimed to assess measles IgG antibody seropositivity and titers in previously vaccinated adults. A cross-sectional study was conducted at CRIE-HC-FMUSP (Sao Paulo, Brazil) in 2019. It included healthy adults who had received two or more Measles-Mumps-Rubella vaccines (MMR) and excluded individuals with immunocompromising conditions. Measles IgG antibodies were measured and compared by ELISA (Euroimmun®) and chemiluminescence (LIASON®). The association of seropositivity and titers with variables of interest (age, sex, profession, previous measles, number of measles-containing vaccine doses, interval between MMR doses, and time elapsed since the last MMR dose) was analyzed. A total of 162 participants were evaluated, predominantly young (median age 30 years), women (69.8%) and healthcare professionals (61.7%). The median interval between MMR doses was 13.2 years, and the median time since the last dose was 10.4 years. The seropositivity rate was 32.7% by ELISA and 75.3% by CLIA, and a strong positive correlation was found between the tests. Multivariate analyses revealed that age and time since the last dose were independently associated with positivity. Despite being a single-center evaluation, our results suggest that measles seropositivity may be lower than expected in adequately immunized adults. Seropositivity was higher among older individuals and those with a shorter time since the last MMR vaccine dose.

ABSTRACT Purpose To investigate if the narrative score of the ProNOH protocol allows for discriminating age groups, as well as its relation with the global coherence level of the story. The performance of preschool and schoolchildren on the macrostructure aspects. Methods Participants were 97 preschoolers and schoolchildren with typical language development, aged between five and 12 years old, and both sexes who attended public schools. The “Protocolo de Avaliação da Narrativa Oral de História (ProNOH)” (Protocol for the Evaluation of Oral Storytelling) was applied and the narrative score in the macrostructure dimension was calculated with story grammar elements. These same story elements were used to obtain the global coherence level of the story, as proposed by Spinillo and Martins (1997). Results A statistically significant difference was found between age groups, mainly between the borderline ages of 5-6 years, 7-8 years, 9-10 years, and 11-12 years. Positive and statistically significant correlations were found between the narrative score and global coherence and age, as well as between the narrative score and global coherence. Conclusion The protocol proved to be useful for identifying the repertoire of typical story grammar elements as an objective measure that differs in oral narrative across age groups. The results also indicate that the narrative score can provide an idea about the global coherence of the story, although this value does not replace a specific analysis.

RESUMO Objetivo Investigar se o escore narrativo obtido por meio da aplicação do “Protocolo de Avaliação da Narrativa Oral de História (ProNOH)” permite discriminar os grupos etários estudados, bem como sua relação com o nível de coerência global da história. Método Participaram 97 pré-escolares e escolares com desenvolvimento típico de linguagem, entre 5 e 12 anos, ambos os sexos que frequentavam escola pública. Foi aplicado o “Protocolo de Avaliação da Narrativa Oral de História (ProNOH)” e calculado o escore narrativo na dimensão macroestrutural a partir dos elementos estruturais previstos no modelo da gramática de história. Esses mesmos elementos foram usados para obter o nível de coerência global da história, segundo proposta de análise de Spinillo e Martins (1997). Resultados Diferença estatisticamente significante foi encontrada entre os grupos etários, principalmente entre as idades fronteiriças de 5-6 anos, 7-8 anos, 9-10 anos e 11-12 anos. Correlação positiva e estatisticamente significante foi encontrada com a idade e o escore narrativo e a coerência global, bem como entre o escore narrativo e o nível de coerência global. Conclusão O protocolo mostrou ser útil para identificar o repertório de elementos típicos da gramática de história na narrativa oral como uma medida objetiva que diferenciou a narrativa oral de grupos etários. Os resultados indicaram ainda que o escore narrativo pode ser uma medida norteadora do nível de coerência da história, apesar deste valor não substituir uma análise específica.

ABSTRACT Agroecological management is considered a model of sustainable agriculture that offers social, environmental and economic benefits. The hypotheses of this study were that agroecological production systems can promote changes in the physical fractions of soil organic matter (SOM) associated with aggregates of different origins, and that the greater diversity of plant species in the production system may favour an increase in the carbon concentration of these aggregates. The aim of this study was to a) determine the mass of the free light fraction (FLF), intra-aggregate light fraction (ILF) and light organic matter fraction (LOM) of biogenic and physiogenic soil aggregates; and b) quantify the organic carbon content of the three light SOM fractions and the residual particulate SOM fraction. Five production systems were evaluated: AgF - Agroforestry system; CSun - Coffee grown in full sun; CSha - Coffee grown in shade; FLE - Flemingia grown in alleys; and NT - No-tillage. The aggregates were separated, identified and classified according to their origin or formation pathway into biogenic (formed by biological processes) or physiogenic aggregates (resulting from chemical and physical actions). From these, the mass and carbon content of the FLF, ILF, LOM and residual particulate fractions were quantified. The greater diversity of plant species found in the AgF system has not yet favoured an increase in the carbon content of the aggregates. The longer set-up time and the management practices of the CSun system has led to an increase in the carbon content of the organic fractions of the aggregates (3.44-1.63 g kg-1 for C-LOM; 1.93-1.13 g kg-1 for C-FLF). The lowest overall mean values for LOM and ILF were found mainly in the aggregates of the NT system (1.22-1.67 and 1.55-2.20 g kg-1, respectively), being associated with the shorter time and greater mobilisation of the arable layer. Biogenic aggregation afforded the highest overall mean values for LOM, and increased the mass of the light fractions (15.5%-27.8% for FLF; 23.4%-8.0% for ILF) and the carbon in the C-LOM, C-FLF and residual particulate fractions (42.3%, 12.9%, and 35.0%, respectively) in the surface layer, suggesting an improvement in soil quality.

ABSTRACT: This study evaluated the effect of black wattle (Acacia mearnsii) condensed tannin extract in simple and complex diets for weaned piglets on performance, faecal consistency and serum haptoglobin concentrations. Eighty-eight female and castrated male piglets were used, weaned at 28 ± 3 days old, with an initial body weight of 8.02 ± 1.21 kg, housed in same-sex pairs and distributed in four treatments in a 2 x 2 factorial experiment in a randomised complete block design. The experimental treatments were simple diet (SD), simple diet + tannin (SD+T), complex diet (CD) and complex diet + tannin (CD+T). The simple diets contained lower concentrations of dairy ingredients, inclusion of barley and no addition of zinc oxide, palatant, acidifier and yeast. The diets with tannin were supplemented with 1,850 mg kg-1 of black wattle condensed tannin extract. The feed programme consisted of three diets: Pre-starter I (0-7 days), Pre-starter II (8-21 days) and Starter (22-28 days). Feed and water were available ad libitum. Body weight and feed intake were measured weekly to calculate the average daily feed intake, daily weight gain and feed conversion ratio. The faecal consistency score was measured daily to calculate the diarrhoea occurrence percentage. Blood samples for serum haptoglobin concentration were collected at 7 and 14 days after weaning. The addition of condensed tannin had no effect (P > 0.05) on evaluated performance variables for weaned piglets. The diet type also did not affect the piglets’ performance (P > 0.05). The inclusion of black wattle (Acacia mearnsii) condensed tannin does not affect piglet performance, reduces the incidence of diarrhoea in the first week after weaning and decreases the haptoglobin inflammatory response.

RESUMO: O objetivo do estudo foi avaliar o efeito de extrato de tanino condensado de acácia-negra (Acacia mearnsii) no desempenho, consistência fecal e concentração sérica de haptoglobina em leitões na fase de creche. Foram utilizados 88 leitões desmamados aos 28±3 dias, com peso vivo médio inicial 8,02 ± 1,21 kg, alojados em duplas de mesmo sexo, e distribuídos em quatro tratamentos em um delineamento de blocos inteiramente ao acaso, em esquema fatorial 2 x 2. Os tratamentos experimentais foram: dieta simples (SD); dieta simples + tanino (SD+T); dieta complexa (CD) e dieta complexa + tanino (CD+T). As dietas simples foram formuladas com menores concentrações de derivados de leite, inclusão de cevada e sem adição de óxido de zinco, palatabilizante e levedura. As dietas com inclusão de tanino foram suplementadas com 1850 mg kg-1 de extrato concentrado de tanino de acácia negra. O programa alimentar foi constituído de três dietas: Pré-inicial I (0 a 7 dias), Pré-inicial II (8 a 21 dias) e Inicial (22 a 28 dias). Ração e água ficaram disponíveis ad libitum. O peso e o consumo de ração dos leitões foram mensurados semanalmente, para calcular a média diária de consumo, o ganho de peso diário e a conversão alimentar. O índice de consistência fecal foi medido diariamente para calcular a porcentagem de ocorrência de diarreia. Amostras de sangue para concentração sérica de haptoglobina foram coletadas aos sete e 14 dias após o desmame. A adição de tanino condensado não teve efeito (P > 0,05) no desempenho de leitões desmamados. O tipo de dieta também não afetou o desempenho dos leitões (P > 0,05). A inclusão do tanino condensado de acácia-negra (Acacia mearnsii) não afetou desempenho, reduziu a incidência de diarreia na primeira semana após o desmame, e diminuiu a resposta inflamatória da haptoglobina.

Resumo: Introdução: A investigação sobre a primeira fase do confinamento devido à COVID-19 em Itália mostrou que se observou um aumento da suscetibilidade a problemas de saúde mental (SM) na população. Na mesma amostra, investigámos as correlações entre as diversas dimensões demográficas, socioeconómicas, historial biológico/clínico e dimensão cognitivo-afetivas e a SM na segunda fase, de “abertura”, do confinamento. Métodos: Foi realizado um questionário online anónimo, com dados recolhidos entre 26 de maio e 4 de julho de 2020, sobre dados demográficos, socioeconómicos, risco percebido, saúde geral, qualidade de vida, preocupação, interferência na vida, satisfação com a vida, felicidade percebida e SM, usando o Inventário de Saúde Mental-5 (MIH-5). Resultados: Embora 300 participantes tenham respondido à secção demográfica e socioeconómica do questionário, apenas 202 responderam à secção de SM neste estudo exploratório. Usando pontuações totais do MHI-5 >52 para baixo distress e >70 para baixa depressão como pontos de corte, mostrámos que a idade avançada estava positivamente associada a melhor SM. Além disso, avaliações positivas mais baixas para a saúde geral e uma maior interferência na vida e na satisfação com a vida foram consideradas preditores de pior SM. Discussão: Durante a segunda fase do confinamento, o impacto das restrições da COVID-19 na SM dependeram da idade do sujeito. Apesar de indivíduos mais velhos apresentarem maior dificuldade no controlo da dor durante o período pandémico, relataram menor preocupação com as despesas diárias e com o futuro e menor interferência das restrições pandémicas na sua atividade laboral e na vida em geral. Independentemente da idade, a saúde mental estava associada à saúde geral autorreportada e à interferência da pandemia na vida e na satisfação com a vida em adultos durante o confinamento devido à COVID-19. Os resultados deste estudo indicam que os indivíduos mais jovens são os mais vulneráveis perante eventos de vida negativos significativos, tais como, a pandemia, e que esta vulnerabilidade aumenta quando os indivíduos têm uma menor capacidade de lidar com a interferência na vida e menor satisfação com a vida devido ao isolamento criado pelo confinamento. Assim, um sistema de saúde pró-ativo que cuide da saúde mental, especialmente entre os jovens, e programas destinados a promover a saúde mental devem ser estabelecidos nas instituições públicas, especialmente nas escolas.

Abstract: Introduction: Research into the first phase of the COVID-19 lockdown in Italy showed an association with an increased susceptibility to adverse mental health (MH) in the general population. We investigated in the same population the correlations between the various demographic, socioeconomic, biological/clinical history and psychological dimensions and MH in the second, “opening-up”, phase of the lockdown. Methods: An anonymous online survey collected data from 26 May to 4 July 2020 on demographic, socioeconomic, perceived risk, general health and quality of life appraisals, worry, interference in life, life satisfaction, perceived happiness and MH by using Mental Health Inventory-5 (MHI-5). Results: Of the 300 participants, only 195 responded to MH questions. Older age was positively associated with better MH (r=.15), as was education (r=.19). A negative correlation with MH, with medium-high effect size, was found with quality of life (r=.40) and health (r=.34) appraisals, and the factors “worry about sustenance” (r=.23) and “interference with life” (r=.32). A positive correlation, with strong effect size, was found between MH and life satisfaction (r=.53) and perception of happiness (r=.64). Discussion: During phase two of the lockdown, rather the real impact of COVID-19 restrictions on employment or economic resources, it was worry about finances that was associated with worse MH. Mental distress was associated with the loss of some positive psychological factors. From a homeostatic and biopsychosocial perspective of MH, life satisfaction and perceived happiness represent important mental resources for counteracting the effects of lockdown on MH.

Resumo Este estudo objetivou estimar a prevalência de osteoporose em idosos atendidos em um centro de referência e identificar fatores associados. Trata-se de um estudo transversal, analítico, com coleta de dados em prontuários médicos e entrevistas aos idosos atendidos no Centro de Referência em Assistência à Saúde dos Idosos (CRASI), e que realizaram exame de densitometria óssea nos anos de 2017 e 2018. Utilizou-se análise bivariada para investigar a associação entre osteoporose e características do grupo: perfil sociodemográfico, Índice de Massa Corporal (IMC), hábitos de vida, cuidados e condições de saúde. As variáveis com associação até o nível de 20% (p ≤ .20) foram avaliadas de forma conjunta por regressão múltipla de Poisson com estimador robusto, admitindo-se para o modelo final apenas as variáveis com nível de significância de até 5%. A prevalência de osteoporose foi de 48.5%. No modelo final ficaram associadas as variáveis: sexo feminino (RP = 1.88; IC95%: 1.36 - 2.60), idade acima de 80 anos (RP = 1.55; IC95%: 1.29 - 1.85), IMC menor que 22 (RP = 1.23; IC95%: 1.02 - 1.49) e como protetor IMC acima de 27 (RP = .52; IC95%: .41 - .67). Concluindo,verificou-se alta prevalência de osteoporose e associação como fator modificável o baixo peso e outros não modificáveis: sexo e idade. Não foram identificadas associações com variáveis relacionadas aos hábitos de vida.

Abstract This study aimed to estimate the prevalence of osteoporosis among elderly individuals receiving treatment at a designated reference center and to identify associated factors. The research employed a cross-sectional, analytical design, involving the collection of data from medical records and interviews with elderly individuals undergoing treatment at the Reference Center for Health Care for the Elderly (CRASI), specifically those who underwent bone densitometry examinations in the years 2017 and 2018. Bivariate analysis was conducted to explore the association between osteoporosis and various group characteristics, including sociodemographic profile, Body Mass Index (BMI), lifestyle habits, care, and health conditions. Variables showing an association up to a significance level of 20% (p ≤ .20) were collectively evaluated through Poisson multiple regression with a robust estimator. Only variables demonstrating a significance level of up to 5% were admitted to the final model. The prevalence of osteoporosis was found to be 48.5%. In the final model, the following variables were identified as being associated: female sex (RP = 1.88; 95%CI: 1.36 - 2.60), age over 80 years old (RP = 1.55; 95%CI: 1.29 - 1.85), BMI less than 22 (RP = 1.23; 95%CI: 1.02 - 1.49), and as a protective factor, BMI above 27 (RP = .52; 95%CI: .41 - .67). In conclusion, a high prevalence of osteoporosis was observed, with associations identified between osteoporosis and modifiable factors such as low weight, as well as non-modifiable factors including sex and age. No significant associations were discerned with variables related to lifestyle habits.

Resumen Introducción y objetivos: Comparar las características clínicas y los resultados de cohortes contemporáneas de pacientes menores y mayores de 70 años que han sido sometidos a ablación de fibrilación auricular (FA) mediante catéter. Métodos: Se llevó a cabo un estudio de cohortes retrospectivo en pacientes sometidos a ablación con catéter debido a la presencia de FA refractaria. Se realizó un seguimiento mínimo de 12 meses por paciente. Resultados: En el estudio se incluyeron un total de 239 pacientes sometidos a ablación de FA, de los cuales 171 (71,5%) pertenecían al grupo de edad < 70 años y 68 (28,5%) al grupo de edad > 70 años. La edad promedio de la población estudiada fue de 62,4 años (desviación estándar [DE] = 10,87). El grupo < 70 años presentó una edad promedio de 58,03 años (DE = 9,71), mientras que el grupo > 70 años tuvo una edad promedio de 73,4 años (DE = 3,05). Además, se observó una mayor prevalencia de FA paroxística en el grupo de pacientes menores de 70 años, mientras que en el grupo de pacientes mayores de 70 años se encontró una mayor prevalencia de FA persistente. Estas diferencias fueron estadísticamente significativas en ambos casos. Las tasas de recurrencia después del primer procedimiento de ablación fueron similares entre los dos grupos (21,43% en el grupo menor de 70 años frente a 23,53% en el grupo mayor de 70 años, p = 0,79). No se encontraron diferencias significativas en cuanto a complicaciones. El grupo menor de 70 años experimentó 18 complicaciones, mientras que el grupo mayor de 70 años tuvo 5 complicaciones, con un valor de p de 0,472. Conclusión: Los pacientes mayores de 70 años sometidos al primer procedimiento de ablación de FA por catéter presentan resultados clínicos similares a los pacientes menores de 70 años.

Abstract Introduction and objectives: The objective of this study is to compare the clinical characteristics and outcomes of contemporary cohorts of patients undergoing catheter ablation for atrial fibrillation (AF), stratified by age (< 70 years and ≥ 70 years). Methods: This retrospective cohort study included patients who underwent catheter ablation for refractory AF. The minimum follow-up duration per patient was 12 months. Results: A total of 239 patients were included in the study, with 171 (71.5%) in the < 70 years group and 68 (28.5%) in the ≥ 70 years group. The mean age of the study population was 62.4 years (SD 10.87). The < 70 years group had a mean age of 58.03 years (SD 9.71), while the ≥ 70 years group had a mean age of 73.4 years (SD 3.05). Furthermore, a higher proportion of paroxysmal AF was observed in patients < 70 years, whereas a higher proportion of persistent AF was found in patients ≥ 70 years. These differences were statistically significant. The recurrence rates after the initial ablation procedure were similar between the two groups (21.43% in the < 70 years group vs. 23.53% in the ≥ 70 years group, p = 0.79). Additionally, there were no significant differences in terms of complications. The < 70 years group experienced 18 complications, while the ≥ 70 years group had 5 complications (p = 0.472). Conclusion: The findings of this study suggest that patients aged 70 years and older who undergo their first catheter ablation procedure for AF demonstrate similar clinical outcomes compared to patients younger than 70 years.

ABSTRACT Objective: To compare, within a cohort of patients with acute respiratory failure, the phenotypes of patients with and without COVID-19 in the context of the pandemic and evaluate whether COVID-19 is an independent predictor of intensive care unit mortality. Methods: This historical cohort study evaluated 1001 acute respiratory failure patients with suspected COVID-19 admitted to the intensive care unit of 8 hospitals. Patients were classified as COVID-19 cases and non-COVID-19 cases according to real-time polymerase chain reaction results. Data on clinical and demographic characteristics were collected on intensive care unit admission, as well as daily clinical and laboratory data and intensive care unit outcomes. Results: Although the groups did not differ in terms of APACHE II or SOFA scores at admission, the COVID-19 group had more initial symptoms of fever, myalgia and diarrhea, had a longer duration of symptoms, and had a higher prevalence of obesity. They also had a lower PaO2/FiO2 ratio, lower platelet levels than non-COVID-19 patients, and more metabolic changes, such as higher levels of blood glucose, C-reactive protein, and lactic dehydrogenase. Patients with non-COVID-19 acute respiratory failure had a higher prevalence of chronic obstructive pulmonary disease/asthma and cardiopathy. Patients with COVID-19 stayed in the hospital longer and had more complications, such as acute kidney failure, severe acute respiratory distress syndrome and severe infection. The all-cause mortality rate was also higher in this group (43.7% in the COVID-19 group versus 27.4% in the non-COVID-19 group). The diagnosis of COVID-19 was a predictor of intensive care unit mortality (odds ratio, 2.77; 95%CI, 1.89 - 4.07; p < 0.001), regardless of age or Charlson Comorbidity Index score. Conclusion: In a prospective cohort of patients admitted with acute respiratory failure, patients with COVID-19 had a clearly different phenotype and a higher mortality than non-COVID-19 patients. This may help to outline more accurate screening and appropriate and timely treatment for these patients.

RESUMO Objetivo: Comparar, em uma coorte de pacientes com insuficiência respiratória aguda, os fenótipos de pacientes com e sem COVID-19, no contexto da pandemia, e avaliar se a COVID-19 é um preditor independente de mortalidade na unidade de terapia intensiva. Métodos: Este estudo de coorte histórico avaliou 1.001 pacientes com insuficiência respiratória aguda e suspeita de COVID-19 internados na unidade de terapia intensiva de oito hospitais. Os pacientes foram classificados como casos com e sem COVID-19 segundo os resultados da RT-PCR. Foram coletados dados sobre características clínicas e demográficas na admissão à unidade de terapia intensiva, bem como dados clínicos e laboratoriais diários e desfechos da unidade de terapia intensiva. Resultados: Embora os grupos não tenham diferido nos escores APACHE II ou SOFA na admissão, o grupo COVID-19 apresentou mais sintomas iniciais de febre, mialgia e diarreia e teve maior duração dos sintomas e maior prevalência de obesidade. Eles também apresentaram menor relação PaO2/FiO2 e níveis mais baixos de plaquetas do que os pacientes sem COVID-19 e mais alterações metabólicas, como níveis mais altos de glicemia, proteína C-reativa e desidrogenase lática. Os pacientes com insuficiência respiratória aguda sem COVID-19 apresentaram maior prevalência de doença pulmonar obstrutiva crônica/asma e cardiopatia. Os pacientes com COVID-19 permaneceram mais tempo no hospital e tiveram mais complicações, como insuficiência renal aguda, síndrome do desconforto respiratório agudo grave e infecção grave. A taxa de mortalidade por todas as causas também foi maior nesse grupo (43,7% no grupo com COVID-19 versus 27,4% no grupo sem COVID-19). O diagnóstico de COVID-19 foi um preditor de mortalidade na unidade de terapia intensiva (razão de chances de 2,77; IC95% 1,89 - 4,07; p < 0,001), independentemente da idade ou da pontuação do Índice de Comorbidade de Charlson. Conclusão: Em uma coorte prospectiva de pacientes admitidos com insuficiência respiratória aguda, os pacientes com COVID-19 apresentaram fenótipo claramente diferente e uma mortalidade mais alta do que os pacientes sem COVID-19. Isso pode ajudar a traçar uma triagem mais precisa e um tratamento adequado e oportuno para esses pacientes.

Abstract Introduction : There is scarce information on longterm evolution of hospitalized patients with moderate (MP) and severe (SP) COVID-19 pneumonia. Objective: to de termine clinical, respiratory function, and tomographic (HRCT) impact after being discharged 12 months after diagnosis. Methods : Analysis according to MP and SP, desatura tor patients (DP) in 6-minute walking test (6MWT) and HRCT fibrotic-like pattern (FLP). Results compared at 3 and 12 months of follow-up. Results : 194 patients enrolled and one year later 103 (53%) were evaluated: gender male (62.4%), age 57.7 ± 10.9 years, comorbidities (arterial hypertension 38.8%, diabetes 29.6%, and respiratory diseases-RD-18.4%). Variables compared 3 months to 12 months (mean/SD): FVC: 84%( 19) to 88%( 19) (p= 0.01). A 27% of patients had FVC<80% at one year. In 6MWT:426 (108) to 447 (92) (p = <0.01). 12.8% are DP in one year. SP had a greater FLP than MP (40% vs. 27.9%, p = 0.021). The FLP group was related to FVC < 80% (p = 0.004) in all patients but only in SP (p < 0.001). After one year, in multivariate analysis, FVC < 80% was associated with RD (OR 4.32, 1.15-16.25), diabetes (OR 2.96, 1.02-8.57) and FLP (OR 3.51, 1.25-9.88). DP were associated with RD (OR 12.2, 2.41-61.85). Discussion : Improvement was observed in all vari ables when comparing 3 to 12 months. However, after one year, functional and tomographic alterations persist in less than 50% of patients. DP subgroup was related to RD. Protocolled follow-up of hospitalized patients is important, especially in SP, DP, and FLP groups.

Resumen Introducción : Hay información escasa sobre evolución a largo plazo de pacientes hospitalizados por neumo nía COVID-19 moderada (NM) y grave (NG). El objetivo del estudio fue determinar impacto clínico, funcional respiratorio y tomográfico (TACAR) luego del alta a 12 meses del diagnóstico. Métodos : análisis según grupos NM y NG, desatura dores (PD) en prueba de caminata 6 min (PC6M) y patrón tomográfico símil fibrótico (SF). Comparamos resultados a 3 y 12 meses de seguimiento. Resultados : 194 pacientes enrolados, evaluados al año: 103 (53% ): masculinos (62.4%), edad 57.7 ± 10.9 años, comorbilidades (hipertensión arterial 38.8%, dia betes 29.6%, antecedentes respiratorios-AR- 18.4%). Com paramos variables a los 3 y 12 meses (media/DE): CVF 84%(19) a 88(19) (p = 0.01); 27% tuvo CVF<80% al año. En PC6M: 426 metros (108) a 447(92) (p = < 0.01). El 12.8% fue PD al año. NG tuvo mayor SF (40% vs. 27.9% p = 0.021). SF se relacionó con CVF <80% (p = 0.004) en toda la co horte, y NG (p < 0.001). Al año en análisis multivariado se asoció a CVF <80%, AR (OR 4.32, 1.15-16.25), diabetes (OR 2.96, 1.02-8.57) y patrón SF (OR 3.51, 1.25-9.88). PD se asoció a AR (OR 12.2, 2.41-61.85). Discusión : Se observó mejoría en todas las variables al año. Pero al año persisten alteraciones funcionales y tomográficas en <50% de los pacientes. El subgrupo de PD se relacionó a AR. Es importante el seguimiento protocolizado de los pacientes hospitalizados, especial mente los grupos NG, PD y SF.

Abstract Introduction : Mortality of infective endocarditis (IE) in Argentina continues to be high. The aim objective was to describe the clinical characteristics and identify factors associated with in-hospital and long-term mortality in patients with native valve IE. Methods : Retrospective cohort study including adult patients with diagnosis of native valve IE, hospitalized during 2011-2021. Results : A total of 129 patients with a mean age of 66±17 years were included. The most frequent respon sible organism was Staphylococcus aureus (SA) (38.8%). Surgical indication criteria were present in 63.6% of the patients. Mortality during hospitalization was 22.5% .In the multivariate analysis that included Charlson comorbidity index, SA infection and the presence of surgical indication criteria, an adjusted OR of mor tality of 1.32 (95%CI 1.10-1.57; p = 0.003), 2.75 (95%CI 1.11-6.8; p = 0.028) and 4.14 (95%CI 1.34-12; p = 0.013), respectively, was observed. In the multivariate analysis for long term mortality, that added surgical indication criteria and the performance of surgery during hospitalization, an adjusted OR of 1.62 (CI95% 1.31-2.00; p<001), 0.77 (95%CI 0.31-1.93; p = 0.58), 7.49 (95%CI 2.07-27.07; p = 0.002) and 0.21 (95%CI 0.06-0.70; p = 0.01), respec tively, was observed. Conclusions : Mortality in IE was associated with the degree of previous comorbidity, with the presence of surgical indication criteria and, inversely, with the timely completion of surgical treatment.

Resumen Introducción : La mortalidad de la endocarditis infec ciosa (EI) en Argentina continúa siendo elevada. El obje tivo del trabajo fue describir las características clínicas e identificar factores asociados a mortalidad en pacientes con EI de válvula nativa. Métodos : Estudio de cohorte retrospectiva que inclu yó pacientes adultos con diagnóstico de EI de válvula nativa internados durante 2011-2021. Resultados : Se incluyeron 129 pacientes con una edad promedio de 66±17 años. El organismo responsa ble más frecuente (38.8%, n = 50) fue el Staphylococcus aureus (SA). El 63.6% presentó criterios de indicación quirúrgica. La mortalidad durante la internación fue del 22.5%. En el análisis multivariado que incluyó índice de comorbilidad Charlson, infección por SA y la presencia de criterios de indicación quirúrgica, se observó un OR ajustado de mortalidad de 1.32 (IC95% 1.10-1.57; p = 0.003), 2.75 (IC95% 1.11-6.8; p = 0.028) y 4.14 (IC95% 1.34-12; p = 0.013), respectivamente. En el análisis mul tivariado para mortalidad alejada que agregó el criterio quirúrgico y la realización de cirugía durante la inter nación, se observó un OR ajustado de 1.62 (IC95% 1.31- 2.00; p < 001), 0.77 (IC95% 0.31-1.93; p = 0.58), 7.49 (IC95% 2.07-27.07; p = 0.002) y 0.21 (IC95% 0.06-0.70; p = 0.01), respectivamente. Conclusiones : La mortalidad de la EI se asoció al grado de comorbilidad previa, a la forma de presenta ción y, en relación inversa, a la realización oportuna del tratamiento quirúrgico.

Abstract In early 2021, the theoretical and legal framework for the termination of pregnancy was modified. From August 2021 until April 2022, a survey was conducted among 310 healthcare staff from the General Hospital for Acute Care Dr. Teodoro Álvarez (HGATA, for its acronym in Spanish) and the Health & Community Action Center No. 34 (CeSAC Nº 34, for its acronym in Spanish) to assess their knowledge of the subject and their ability to provide an adequate response to patients inquiring about the procedure. Out of the total number of people surveyed, 72.9% were women, the largest age group was 26-35 years old and the most mentioned occupation was “resident” (31.3%). According to their answers, the respondents were divided into two groups: those who were informed (8.7%, n = 27) and those who were uninformed (91.3%, n = 283). 100% of the informed group were able to provide patients with a correct response while only 82,7% of the uninformed group were able to do so. The majority of the respondents (85.5%) deemed it helpful to receive training and updates on voluntary termination of pregnancy in the near future. Most of the healthcare staff from the HGATA and from the CeSAC No. 34 are unaware of the theoretical-legal framework under which the interruption of pregnancy is regulated. The uninformed presented difficulties in providing an appropriate response. These results show the formative deficit that exists in relation to the theoretical-legal framework. This information could be useful for the identification of barriers and facilitators of access to an interruption.

Resumen A principios del año 2021 fue modificado el marco teórico-legal bajo el cual se reglamenta la interrupción del embarazo. Entre los meses de agosto 2021 y abril 2022, realizamos una encuesta a 310 trabajadores del Hospital General de Agudos Dr. Teodoro Álvarez (HGATA) y del Centro de Salud y Acción Comunitaria Nº 34 (CeSAC Nº 34), con el objetivo de evaluar su conocimiento al respecto y su capacidad de brindar una respuesta acorde ante la demanda de dicha práctica. Del total de las personas encuestadas, el 72.9% fueron mujeres, el rango etario predominante fue el de 26-35 años y la ocupación mayoritariamente referida fue “residente” (31.3%). Entre los encuestados, definimos dos grupos: conocedores (8.7%, n = 27) y no conocedores (91.3%, n = 283). El 100% de los conocedores brindó una respuesta acorde, mientras que, con relación a los no conocedores, solo el 82.7% pudo hacerlo. La mayoría de los encuestados (85.5%) consideró útil poder recibir capacitación y actualización sobre esta temática en el futuro. Concluimos que la mayoría de los trabajadores del HGATA y del CeSAC Nº 34 desconocen el marco teórico-legal bajo el cual está reglamentada la interrupción del embarazo. Los no conocedores tuvieron dificultades para brindar una respuesta apropiada. Estos resultados muestran el déficit formativo que existe en relación con el marco teórico-legal de esta práctica, por ello, consideramos que esta información sería útil para la identificación tanto de barreras como de facilitadores de acceso a la interrupción del embarazo.

Abstract Introduction: Persistent Postural Perceptual Dizziness (PPPD) is one of the most common causes of chronic vertigo. While patients with PPPD have spatial perception alterations, it is unknown whether they present alterations in fear of heights. To avoid exposing patients with PPPD to high places, we aimed to use virtual reality to quantify fear of heights. Aim: To quantify fear of heights in patients with PPPD and controls using simulated environments with virtual reality. Material and Method: A prospective cross-sectional study of age- and sex-matched case-control pairs. PPPD patients were recruited from the Otolaryngology Service of the Clinical Hospital of the University of Chile between 2020 and 2021. Presence of subjective fear and tachycardia were measured. The scenarios were developed using Blender 2.8 and Oculus Link for the Oculus Quest. Five scenarios at different heights (floors 1, 3, 6, 12, 19) were used. Results: Twenty subjects were recruited (12 women, average age of 47 years), including 10 PPPD patients and 10 controls without vestibular symptoms. None of the control group subjects presented fear in the presented scenarios, while seven patients in the PPPD group had subjective fear at a height lower than virtual 40 meters (Fischer, p < 0.05). Conclusion: Patients with PPPD present a greater proportion of subjective fear to heights than controls, but further studies are required to determine if this fear is specific to PPPD or is general to other causes of chronic vertigo.

Resumen Introducción: El mareo postural perceptual persistente (MPPP) es una de las causas más frecuentes de vértigo crónico. Si bien, los pacientes con MPPP tienen alteraciones de la percepción espacial, se desconoce si presentan alteraciones en el miedo a las alturas. Para no exponer a pacientes con MPPP a ambientes reales con altura, nos propusimos utilizar la realidad virtual para estudiar el miedo a las alturas. Objetivo: Cuantificar el miedo a las alturas en pacientes con MPPP y controles mediante ambientes simulados con realidad virtual. Material y Método: Estudio transversal, prospectivo de casos y controles pareados por edad y sexo. Se reclutaron pacientes con MPPP del Servicio de Otorrinolaringología del Hospital Clínico de la Universidad de Chile entre los años 2020 y 2021. Se midió presencia subjetiva de miedo y taquicardia. Los escenarios se desarrollaron con el programa Blender 2.8 y Oculus Link para equipo Oculus Quest. Se utilizaron cinco escenarios a diferentes alturas (pisos 1, 3, 6, 12, 19). Resultados: Se reclutaron 20 sujetos (12 mujeres, 47 años en promedio), incluyendo 10 pacientes con MPPP y 10 controles sin síntomas vestibulares. Ningún sujeto del grupo control presentó miedo en los escenarios presentados, mientras que siete pacientes del grupo MPPP tuvieron miedo subjetivo a una altura menor a 40 metros virtuales (Fischer, p < 0,05). Conclusión: Los pacientes con MPPP presentan, con mayor frecuencia, miedo subjetivo a las alturas que los controles, pero se requiere de nuevos estudios para determinar si este miedo es específico de MPPP, o es general a otras causas de vértigo crónico.

RESUMEN La infiltración cutánea por células leucémicas conocida como leucemia cutis es una presentación infrecuente de esta patología y constituye un desafío diagnóstico. Los diagnósticos como infecciones, otras patologías neoplásicas con afectación cutánea y los trastornos histiocíticos, entre otros, constituyen los principales diagnósticos diferenciales, ya que configuran un escenario pronóstico y terapéutico diferente. Se presentan dos pacientes que fueron diagnosticados inicialmente como leucemia cutis, cuyo diagnóstico final fue de patologías no malignas.
