Resumo Introdução O monitoramento da hipertensão arterial sistêmica (HAS) é realizado no Brasil, fundamentado no autorrelato, por meio do sistema VIGITEL. Tendo em vista lacunas acerca desse agravo em populações de trabalhadores, estas devem ser alvo da ação ampliada para o seu diagnóstico epidemiológico. Objetivo Testar a validade de critério do autorrelato de HAS, comparando-o com medidas aferidas de pressão arterial (PA). Método Realizou-se estudo de corte transversal com amostra aleatória do universo de 1.561 trabalhadores de um serviço judiciário na Bahia. Calcularam-se sensibilidade, especificidade, valores preditivos e razões de probabilidade para o autorrelato de HAS, comparando-os com a aferição direta da PA, medida de referência. O diagnóstico de HAS foi a média de duas aferições com PA sistólica ≥ 140 mmHg, e/ou PA diastólica ≥ 90 mmHg, e/ou uso regular de anti-hipertensivos. Resultados Em amostra de 391 trabalhadores, verificou-se sensibilidade de 66,4% (57,1-74,6%), especificidade de 87,9% (83,2-91,4%), valor preditivo positivo de 70,5% (61,1-78,6%), valor preditivo negativo de 85,7% (80,9-89,4%), razões de probabilidade positiva e negativa de 5,5 (3,88-7,72) e de 0,4 (0,30-0,49), respectivamente. Conclusão Este estudo evidenciou o autorrelato como medida válida para o diagnóstico epidemiológico da HAS entre trabalhadores, recomendando seu uso. No entanto, esta validade depende do diagnóstico prévio do agravo.

Abstract Background Monitoring of hypertension, based on self-report, has been performed in Brazil through VIGITEL. In view of the gaps about this problem in worker populations, these should be the targets of the expanded action of epidemiological diagnosis of hypertension. Objective To test the validity of hypertension self-report in comparison to blood pressure (BP) measurements. Method A cross-sectional study was conducted on a random sample of 1561 workers from a Judicial Service in Bahia. Sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios were calculated for the hypertension self-report in comparison with direct BP measurement (reference). Hypertensive cases presented the mean of two BP measurements, with systolic BP ≥ 140 mmHg, and/or diastolic BP ≥ 90 mmHg and/or regular use of antihypertensive drugs. Results In a sample of 391 workers, there was a sensitivity of 66.4% (57.1-74.6%), a specificity of 87.9% (83.2-91.4%), a positive predictive value of 70.5% (61.1- 78.6%), a negative predictive value of 85.7% (80.9-89.4%), a positive and negative likelihood ratio of 5.5 (3.88-7.72) and 0.4 (0.30-0.49) respectively. Conclusion This study showed self-report as a valid measure to implement the epidemiological diagnosis of hypertension among workers, recommending its use. However, its validity depends on the previous diagnosis.

Anthropometric indicators of adiposity as predictors of systemic arterial hypertension in older people: a cross-sectional analysis / Indicadores antropométricos de adiposidade como preditores de hipertensão arterial sistêmica em pessoas idosas: uma análise transversal

ABSTRACT Objective: To analyze the association of anthropometric indicators of adiposity in older people, according to sex, with hypertension; to compare the scores of these variables between participants with and without hypertension; and to identify among them those with better predictive ability for screening the outcome. Methods: Epidemiological, population-based, cross-sectional study conducted with 210 older people. The anthropometric indicators analyzed were: body mass index, waist circumference, abdominal circumference, body adiposity index, triceps skinfold, waist-to-hip ratio, waist-to-height ratio, and conicity index. Hypertension diagnosis was self-reported. Results: The indicators of adiposity increased the probability of hypertension. Additionally, hypertensive older people of both sexes showed higher scores on adiposity indicators than non-hypertensive subjects (p < 0.05). For men, the most sensitive indicator for the outcome was conicity index (81.82%; cut-off point: 1.30) and the most specific was body mass index (69.77%; cut-off point: 25.05 kg/m2). For women, the most sensitive indicator for the outcome was the body adiposity index (86.08%; cut-off point: 31.03%), and the most specific was the abdominal circumference (82.82%; cut-off point: 98.70 cm). Conclusion: In both sexes, the indicators of adiposity were positively associated with hypertension; hypertensive participants showed higher values in the scores of the indicators. Additionally, the body adiposity index (women) and conicity index (men) demonstrated greater ability to screen for hypertension, while the abdominal circumference and body mass index demonstrated greater ability to screen for non-hypertensive women and men, respectively.

RESUMO Objetivo: Analisar a associação de indicadores antropométricos de adiposidade com a hipertensão, em pessoas idosas, de acordo com o sexo; comparar os escores dessas variáveis entre os participantes com e sem hipertensão; e identificar os indicadores com melhor capacidade preditiva à triagem do desfecho. Métodos: Estudo epidemiológico, populacional, transversal, realizado com 210 pessoas idosas. Os indicadores antropométricos analisados foram: índice de massa corporal, circunferência da cintura, circunferência abdominal, índice de adiposidade corporal, dobra cutânea tricipital, relação cintura/quadril, relação cintura/altura e índice de conicidade. O diagnóstico de hipertensão arterial foi autorreferido. Resultados: Observou-se que os indicadores de adiposidade aumentaram a probabilidade à hipertensão. Além disso, as pessoas idosas hipertensas, de ambos os sexos, apresentaram maiores escores nos indicadores de adiposidade quando comparadas às não hipertensas (p < 0,05). Para os homens, o indicador mais sensível ao desfecho foi o índice de conicidade (81,82%; ponto de corte: 1,30) e o mais específico foi o índice de massa corporal (69,77%; ponto de corte: 25,05 kg/m2). Nas mulheres, o indicador mais sensível ao desfecho foi o índice de adiposidade corporal (86,08%; ponto de corte: 31,03%) e o mais específico foi a circunferência abdominal (82,82%; ponto de corte: 98,70 cm). Conclusão: Em ambos os sexos, os indicadores de adiposidade mostraram-se positivamente associados à hipertensão; os participantes hipertensos apresentaram valores mais elevados nos escores dos indicadores. Ademais, identificou-se para os sexos, feminino e masculino, que os indicadores com melhor capacidade de rastrear a hipertensão, foram, respectivamente, o índice de adiposidade corporal e índice de conicidade. Enquanto a circunferência abdominal e o índice de massa corporal mostraram maior capacidade de rastrear, respectivamente, as mulheres e os homens não hipertensos.

J-shaped association between dietary zinc intake and new-onset hypertension: a nationwide cohort study in China / 医学前沿

We aimed to investigate the relationship of dietary zinc intake with new-onset hypertension among Chinese adults. A total of 12,177 participants who were free of hypertension at baseline from the China Health and Nutrition Survey were included. Dietary intake was assessed by three consecutive 24-h dietary recalls combined with a household food inventory. Participants with systolic blood pressure ≽ 140 mmHg or diastolic blood pressure ≽ 90 mmHg or diagnosed by a physician or under antihypertensive treatment during the follow-up were defined as having new-onset hypertension. During a median follow-up duration of 6.1 years, 4269 participants developed new-onset hypertension. Overall, the association between dietary zinc intake and new-onset hypertension followed a J-shape (P for non-linearity < 0.001). The risk of new-onset hypertension significantly decreased with the increment of dietary zinc intake (per mg/day: hazard ratio (HR) 0.93; 95% confidence interval (CI) 0.88-0.98) in participants with zinc intake < 10.9 mg/day, and increased with the increment of zinc intake (per mg/day: HR 1.14; 95% CI 1.11-1.16) in participants with zinc intake ≽ 10.9 mg/day. In conclusion, there was a J-shaped association between dietary zinc intake and new-onset hypertension in general Chinese adults, with an inflection point at about 10.9 mg/day.

Neste aspecto, pretende Avaliar se há uniformidade entre os dados de prevalência de DM e HA no Estado de Goiás a partir de duas diferentes fontes de acesso a esses dados. Casuística e métodos: Comparação entre os dados do Levantamento de Hipertensão e Diabetes do estado de Goiás 2021 (LHD) e do banco de dados da Estratégia e-SUS Atenção Básica (e-SUS AB) com relação ao número de indivíduos cadastrados na rede de atenção primária à saúde com os diagnósticos de DM e HA. Resultados: Em Goiás, a diferença entre o número absoluto de indivíduos com diagnóstico de DM e HA pelo LHD e pelo e-SUS AB foi de 46,56% e de 27%, respectivamente (p <0,001). A diferença entre os dados foi maior que 50% para o diagnóstico de DM em 104 municípios e para HA em 94 municípios. Discussão: As divergências encontradas podem estar relacionadas a fatores como a qualidade dos dados fornecidos pela população, duplicidade de registros, problemas técnicos relacionados à internet e ao software e dificuldades na integração entre os sistemas de informação. Demonstra-se a necessidade de padronização de registros e uniformização dos dados para o fortalecimento de ações de vigilância. Concluiu que há inconsistências entre os dados sobre o número de indivíduos cadastrados com os diagnósticos de DM e HA a partir do LHD e e-SUS AB em grande parte dos municípios do Estado de Goiás

Introduction: Conformity between data sources on diabetes mellitus (DM) and hypertension (H) is critical for surveillance measures. Objective: To assess whether there is uniformity between data on the prevalence of DM and H in the State of Goiás, based on two different sources of access to these data. Material and methods: A comparison was made between the data from the 2021 Hypertension and Diabetes Survey of the State of Goiás (LHD) and the data from the e-SUS Primary Care Strategy (e-SUS AB) database about the number of people who had hypertension or diabetes. RESULTS: In Goiás, the difference between the absolute number of individuals diagnosed with DM and H according to data from the LHD and e-SUS AB was 46.56% and 27%, respectively (p <0.001). The difference between the data was greater than 50% for the diagnosis of DM in 104 municipalities and for H in 94 municipalities. Discussion: The differences found may be related to the quality of personal data provided by the population, duplicate records, obstacles in using the software or the internet, difficulties in integrating information systems. The findings demonstrate the necessity of establishing standardized records for data related to these diseases in order to strengthen surveillance actions. Conclusion: There are inconsistencies between the data on the number of individuals registered as having DM and H from the LHD and e-SUS AB in most municipalities in the State of Goiás

A diagnostic prediction model for hypertension in Han and Yugur population from the China National Health Survey (CNHS) / 中华医学杂志(英文版)

BACKGROUND@#The prevalence of hypertension is high among Chinese adults, thus, identifying non-hypertensive individuals at high risk for intervention will help to improve the efficiency of primary prevention strategies.@*METHODS@#The cross-sectional data on 9699 participants aged 20 to 80 years were collected from the China National Health Survey in Gansu and Hebei provinces in 2016 to 2017, and they were nonrandomly split into the training set and validation set based on location. Multivariable logistic regression analysis was performed to develop the diagnostic prediction model, which was presented as a nomogram and a website with risk classification. Predictive performances of the model were evaluated using discrimination and calibration, and were further compared with a previously published model. Decision curve analysis was used to calculate the standardized net benefit for assessing the clinical usefulness of the model.@*RESULTS@#The Lasso regression analysis identified the significant predictors of hypertension in the training set, and a diagnostic model was developed using logistic regression. A nomogram with risk classification was constructed to visualize the model, and a website ( https://chris-yu.shinyapps.io/hypertension_risk_prediction/ ) was developed to calculate the exact probabilities of hypertension. The model showed good discrimination and calibration, with the C-index of 0.789 (95% confidence interval [CI]: 0.768, 0.810) through internal validation and 0.829 (95% CI: 0.816, 0.842) through external validation. Decision curve analysis demonstrated that the model was clinically useful. The model had a higher area under receiver operating characteristic curves in training and validation sets compared with a previously published diagnostic model based on Northern China population.@*CONCLUSION@#This study developed and validated a diagnostic model for hypertension prediction in Gansu Province. A nomogram and a website were developed to make the model conveniently used to facilitate the individualized prediction of hypertension in the general population of Han and Yugur.

Study on related factors and characteristics of multimorbidity of overweight and obesity-related diseases in children in Hunan Province / 中华预防医学杂志

From January 2019 to December 2021, overweight and obese children who visited in health outpatient Center of Hunan Children's Hospital were studied to explore and analyze the rate, related factors and patterns of multimorbidity of overweight and obesity-related diseases in children in Hunan Province. Univariate and multivariate logistic regression models were used to analyze the multimorbidity-related factors of overweight and obesity-related diseases in children. Association rules (apriori algorithm) were used to explore the multimorbidity patterns of overweight and obesity-related diseases in children. A total of 725 overweight and obese children were included in this study. The multimorbidity rate of overweight and obesity-related diseases in children was 46.07% (334/725). Age, waist circumference, the frequency of food consumption such as hamburgers and fries and adding meals before bedtime were multimorbidity-related factors of overweight and obesity-related diseases in children. The multimorbidity associated with nonalcoholic fatty liver disease (NAFLD) was relatively common. The patterns with the top three support degrees were "NAFLD+dyslipidemia","NAFLD+hypertension" and "NAFLD+hyperuricemia". The patterns with the top three confidence and elevation degrees were "Hypertension+dyslipidemia => NAFLD","Hyperuricemia => NAFLD" and "NAFLD+hypertension => dyslipidemia".

Association of greenness, nitrogen dioxide with the prevalence of hypertension among the elderly over 65 years old in China / 中华预防医学杂志

Objective: To investigate the association of mixed exposure to greenness and nitrogen dioxide(NO2) and hypertension among the older adults aged 65 years and over in China. Methods: The study subjects were from the Chinese Longitudinal Healthy Longevity Survey from 2017 to 2018. A total of 15 423 older adults aged 65 years and over meeting the criteria were finally included in the study. A questionnaire survey was used to collect information on demographic characteristics, lifestyle habits and self-reported prevalence of hypertension. Blood pressure values were obtained through physical examination. The level of normalized difference vegetation index(NDVI) was measured by the Medium-resolution Imaging Spectral Radiator(MODIS) of the National Aeronautics and Space Administration(NASA). The concentration of NO2 was from China's surface air pollutant data set. Meteorological data was from NASA MERRA-2. The exposure to NDVI and NO2 for each study subject was calculated based on the area within a 1 km radius around their residence. The association between mixed exposure of NDVI and NO2 as well as their interaction and hypertension in older adults was analyzed by using the multivariate logistic regression model. The restrictive cubic spline(RCS) function was used to explore the exposure-response relationship between greenness and NO2 and the risk of hypertension in study subjects. Results: The mean age of 15 423 older adults were (85.6±11.6). Women accounted for 56.3%(8 685/15 423) and 55.6%(8 578/15 423) lived in urban areas. The mean time of residence was (60.9±28.5) years. 59.8% of participants were with hypertension. The mean NDVI level was 0.41±0.13, and the mean NO2 concentration was (32.18±10.36) μg/cm3. The results of multivariate logistic regression analysis showed that NDVI was inversely and linearly associated with the hypertension in older adults, with the OR(95%CI) value of 0.959(0.928-0.992). Compared with the T1 group of NDVI, the risk of hypertension was lower in the T3 group, with the OR(95%CI) value of 0.852(0.769-0.944), and the trend test was statistically significant(P<0.05). Compared with the T1 group of NO2, the risk of hypertension was higher in the T2 and T3 groups, with OR(95%CI) values of 1.160(1.055-1.275) and 1.244(1.111-1.393), and the trend test was statistically significant (P<0.05). The result of the RCS showed that NDVI was inversely and linearly associated with hypertension in older adults. NO2 was nonlinearly associated with hypertension in older adults. The interaction analysis showed that NDVI and NO2 had a negative multiplicative interaction on the risk of hypertension, with OR(95%CI) value of 0.995(0.992-0.997). Conclusion: Exposure to greenness and NO2 are associated with hypertension in older adults.

The distribution of blood pressure and associated factors of the elderly with type 2 diabetes in Jiangsu Province / 中华预防医学杂志

Objective: To investigate the distribution of blood pressure and analyze the associated factors of blood pressure of the elderly with type 2 diabetes in Jiangsu Province. Methods: The elderly over 60 years old participants with type 2 diabetes in the communities of Huai'an City and Changshu City, Jiangsu Province were selected in this study. They were divided into two groups: taking antihypertensive drugs and not taking antihypertensive drugs. The demographic characteristics, such as age and sex, and relevant factors were collected by questionnaire. The systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by physical examination. The percentile of SBP and DBP in each age group of men and women were described. The kernel density estimation curve was used to show the blood pressure distribution. The trend of blood pressure with age was fitted by locally weighted regression. The logistic regression model was used to analyze relevant factors of blood pressure. Results: A total of 12 949 participants were included in this study, including 7 775 patients in the antihypertensive drug group and 5 174 patients in the group without antihypertensive drugs. The SBP of participants was concentrated at 140-160 mmHg, and their DBP was concentrated at 75-85 mmHg. There were significant differences in the distribution of blood pressure among the subgroups of body mass index (BMI) and rural areas whether taking antihypertensive drugs and not. For participants aged under 80 years old, the SBP showed an increasing trend with age and the DBP showed a decreasing trend with age. Age, BMI ≥24 kg/m2, fasting blood glucose ≥7.0 mmol/L, living in rural areas and no smoking were influencing factors of the elevated SBP; BMI ≥24 kg/m2, male, living in rural areas, no smoking, drinking alcohol and not receiving drug hypoglycemic treatment were influencing factors of the elevated DBP. Conclusion: The SBP of older diabetic adults in Jiangsu Province is at a high level, and the distribution of blood pressure is significantly different between men and women in taking antihypertensive drugs group. The SBP presents a rising trend and the DBP is decreasing at the age of 60-80 years. The blood pressure level of this population are mainly affected by age, BMI, urban and rural areas, smoking.

A study on the Charlson comorbidity index and health-related quality of life in the middle-aged and elderly osteoporosis population / 中国骨伤

OBJECTIVE@#To explore the characteristics of comorbidities in patients with osteoporosis(OP) and factors associated health-related quality of life, so as to provide decision-making reference for improving the ability of disease co-prevention and co-treatment and the patient's life-cycle quality of life.@*METHODS@#From November 2017 to July 2018, clinical information and biological samples from residents in 10 communities in Chaoyang District and Fengtai Distric of Beijing were collected, and bone density testing was conducted. Based on the Charlson comorbidity index (CCI), the comorbidity of the population was quantified, and grouped according to factors such as gender, age, and the differences between the groups were explored. Combined with the clinical information of patients, the difference characteristics of comorbidity and non-comorbidity population were analyzed. Pearson/Spearman correlation analysis and binary Logistic regression analysis were used to explore the factors affecting the health-related quality of life in patients with OP.@*RESULTS@#Among the 521 OP patients, 121 patients had no comorbidities, and there were 153, 106, 65, and 30 patients with one, two, three, and four comorbidities, respectively, 46 patients with 5 or more kinds of comorbidites. Hypertension was the most common comorbidity in OP patients, accounting for 21.60%;followed by hyperlipidemia, accounting for 13.51%. The most common combination of the two diseases was hypertension plus hyperlipidemia (64 cases, 12.28%). Through the analysis of differences between age groups, it was found that the older patients, showed higher the CCI, and the difference between groups was statistically significant(Z=1.93, P=0.05). There were significant differences in the total EQ-5D score and the dimensions of anxiety and depression between patients with comorbidities (CCI≠0) and non-comorbidities (CCI=0) (Z=-2.67, P=0.01;Z=-2.44, P=0.02). Correlation analysis found that CCI, history of fracture, history of falls, hip bone mineral density T value and parathyroid hormone were all related to the health-related quality of life in OP patients (P<0.05). Binary Logistic regression analysis suggested that the right hip bone mineral density T value (P=0.02), CCI (P=0.01), fracture history (P=0.03) and fall history (P=0.01) were the risk factors that affect the health-related quality of life in OP patients.@*CONCLUSION@#The burden of comorbidities among middle-aged and elderly OP populations in Beijing is relatively heavy, and the health management of such populations should be further strengthened, specifically the combination of multiple comorbidities should be given high priority. Comorbid factors are of great importance for the diagnosis and treatment strategy of OP patients, which could further improve the quality of life.

Burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in China / 中华流行病学杂志

Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.

Dado que existe limitada información local, el objetivo primario de este estudio fue estimar la prevalencia de CR en nuestro medio. Población y métodos. Estudio transversalrealizado en 13 centros de Argentina entre marzo y diciembre de 2020. Se incluyeron pacientes internados con COVID-19, de 1 mes a 18 años y que tuvieran al menos una determinación de creatinina sérica y/o de orina completa.Se excluyeron aquellos con enfermedad renal conocida. Se consideró CR la presencia de lesión renal aguda (LRA), proteinuria, hematuria, leucocituria y/o hipertensión arterial (HTA). Resultados. De 528 historias clínicas elegibles, seincluyeron las de 423 pacientes (el 55,0 % de sexo masculino, mediana de edad 5,3 años). El cuadro clínico fue asintomático en el 31 %, leve en el 39,7 %, moderado en el 23,9 %, grave en el 1,2 %, crítico en el 0,7 %, y el 3,5 % presentó síndrome inflamatorio multisistémico pediátrico (SIMP). Dos pacientes (0,47 %) fallecieron. La prevalencia de CR fue del 10,8 % (intervalo de confianza 95% 8,2-14,2), expresada por leucocituria (16,9 %), proteinuria (16,0 %), hematuria (13,2 %), HTA (3,7 %) y LRA (2,3 %). Ninguno requirió diálisis. Presentar CR se asoció (p <0,0001) con formas graves de enfermedad. Conclusión. La prevalencia de CR en pacientes pediátricos internados con COVID-19 en 13 centros de nuestro país fue del 10,8 % y predominó en las formas clínicas graves.

Introduction. Renal involvement among pediatric patients with coronavirus disease 2019 (COVID-19) ranges between 1.2% and 44%. Given the limited information available locally, the primary objective of this study was to estimate the prevalence of renal involvement in our setting. Population and methods. Cross-sectional study conducted in 13 Argentine sites between March and December 2020. Patients aged 1 month to 18 years hospitalized due to COVID-19 and with at least one measurement of serum creatinine and/or a urinalysis were included. Those with a known kidney disease were excluded. Renal involvement was defined as the presence of acute kidney injury (AKI), proteinuria, hematuria, leukocyturia and/or arterial hypertension (HTN). Results. Among 528 eligible medical records, 423 patients were included (55.0% were males; median age: 5.3 years). The clinical presentation was asymptomatic in 31%; mild, in 39.7%; moderate, in 23.9%; severe, in 1.2%; critical, in 0.7%; and 3.5% had multisystem inflammatory syndrome in children (MIS-C). Two patients (0.47%) died. The prevalence of renal involvement was 10.8% (95% confidence interval: 8.2­14.2); it was described as leukocyturia (16.9%), proteinuria (16.0%), hematuria (13.2%), HTN (3.7%), and AKI (2.3%). No patient required dialysis. Renal involvement was associated with severe forms of disease (p < 0.0001). Conclusion. The prevalence of renal involvement among pediatric patients hospitalized due to COVID-19 in 13 Argentine sites was 10.8%; severe forms of disease prevailed.

Insuficiencia cardíaca de novo: Un reto diagnóstico / Di novo heart failure: A diagnostic challenge

Introducción: El término insuficiencia cardíaca de novo hace referencia a pacientes sin diagnóstico previo de dicha enfermedad. La revisión de este tema deviene de un problema real, pues muchos pacientes acuden a la atención secundaria sin diagnóstico previo de insuficiencia cardíaca y además en estadios avanzados. Objetivo: Describir los elementos claves para el diagnóstico precoz de insuficiencia Cardíacas. Métodos: Se llevó a cabo una búsqueda bibliográfica en las siguientes bases de datos: Pubmed, SciELO, ESBCO, Cochrane y BVS, así como en diferentes webs médicas durante tres meses entre febrero de 2021 al 31 de mayo de 2021. Conclusiones: El diagnóstico precoz de insuficiencia cardíaca permitió disminuir el número de pacientes que llegan a la Atención Secundaria sin diagnóstico previo. Existen clasificaciones que identifican estadios tempranos de la enfermedad y la de la ACC/AHA es relevante para lograr este objetivo. En atención primaria esto es un reto si no se emplean pruebas diagnósticas como el ecocardiograma. Es importante la determinación de las concentraciones circulantes del péptido natriurético tipo B (BNP) y del fragmento N-terminal de su protohormona (N-terminal BNP). Este biomarcador debería estar accesible en las consultas ambulatorias para pacientes que presentan sospecha clínica de insuficiencia cardíaca «de novo»(AU)

Introduction: The term di novo heart failure refers to patients without a previous diagnosis of this disease. The review of this issue comes from a real problem, since a group of patients attend secondary care without a previous diagnosis of heart failure and also have in advanced stages. Objective: The objective is to provide a clue that facilitates the early diagnosis of heart failure. Methods: A bibliographic search was carried out in the following databases: Pubmed, SciELO, ESBCO, Cochrane and BVS, as well as in different medical websites for three months (February 1, 2021 to May 31, 2021). Conclusions: The early diagnosis of heart failure will allow us to reduce the number of patients who arrive at Secondary Care without a previous diagnosis. There are classifications that identify early stages of the disease, being in our opinion the ACC / AHA classification the one that should carry the most weight. In primary care this can be a challenge if diagnostic tests such as echocardiography are not used. Dosification of serum levels of type B natriuretic peptide (BNP) and the N-terminal fragment of its protohormone (N-terminal BNP) is very useful. This biomarker should be accessible in outpatient clinics for patients with clinical suspicion of di novo heart failure(AU)

Características clínicas, evolución y factores pronósticos asociados con mortalidad en adultos mayores hospitalizados por COVID-19 en una Unidad Geriátrica de Agudos / Evolution and prognostic factors associated with mortality in older adults hospitalized for COVID-19 Cecilia Carvachoa

BACKGROUND: SARS-CoV-2 affects all age groups, but higher mortality rates are recorded in older people, men and with comorbidities, mainly hypertension, diabetes and obesity. Aim: To describe the main clinical characteristics, evolution and prognostic factors for death in older patients hospitalized for COVID-19. MATERIALS AND METHODS: Retrospective analysis of 128 patients aged 73 years, 66% men, hospitalized at a clinical hospital, with a diagnosis of COVID-19, admitted from May 1 to August 1, 2020. Data were collected from the clinical records, a description of the study population was made, and a univariate analysis and logistic regression were performed. Results: Seventy-two percent of patients had two or more comorbidities, mainly arterial hypertension in 66%, diabetes mellitus in 34% and cardiovascular disease in 19%. Forty-one percent were admitted to intensive care and 31% were connected to mechanical ventilation. In-hospital mortality was 26.6%. A multivariate analysis was performed in two blocks, finding in the first that arterial hypertension and older age significantly predict mortality. However, when previous institutionalization and immuno-suppression were included as variables in the second block, age ceased to be a significant predictor. CONCLUSIONS: Prognostic factors associated with death in this age group are arterial hypertension and previous institutionalization.

Prescription of statins according to the ASCVD estimator at Pablo Arturo Suarez Hospital, March 2021 to February 2022 / Prescripción de estatinas según el estimador ASCVD en el Hospital Pablo Arturo Suárez, marzo 2021 a febrero 2022

Worldwide, the leading cause of death is cardiovascular disease. The study details the prescription of statins at the Pablo Arturo Suarez Hospital in Ecuador between March 2021 and February 2022 following the ASCVD risk scale of the American College of Cardiology and the American Heart Association. There are 563 people in this cross-sectional and retrospective study: 70% women, 30% men, 93.30% mestizos, 48.10% diabetics, 62.30% hypertensives, and 18.70% smokers. 26.10% of all patients received statins, with simvastatin being the most common (96.60%). The mean cardiovascular risk in the general population was 15.52 ± 14.51%, 44.99% of subjects had a risk lower than 7.50%, and 29% had a risk higher than 20%, with a statistically significant difference (p<0.001) according to sex. The study determined that 58.60% of the population received a statin or an inadequate dosage.

Infecciones periprotésicas en artroplastia total de rodilla: ¿cuál es nuestra realidad? / Periprosthetic infections in total knee arthroplasty: what is our reality?

INTRODUCCIÓN La infección periprotésica (IPP) es una de las complicaciones más serias en una artroplastia total de rodilla (ATR). Pese a esto, existe poca literatura chilena respecto de esta patología. OBJETIVOS Determinar la incidencia, las comorbilidades, los microorganismos aislados y su susceptibilidad antibiótica, y la morbimortalidad en pacientes con IPP. MATERIALES Y MÉTODOS Estudio descriptivo y retrospectivo en pacientes operados entre 2001 y 2020 por gonartrosis, con una ATR primaria, en un mismo centro de salud, con al menos 1 año de seguimiento. Se excluyeron pacientes operados en otros centros o con registros clínicos incompletos. Se registraron las comorbilidades, los microorganismos aislados, la susceptibilidad antibiótica, y la sobrevida por medio de una búsqueda sistemática de las fichas clínicas de los pacientes con IPP. Se utilizó estadística descriptiva para presentar los datos. RESULTADOS Se incluyeron 544 ATRs, de las cuales 8 (1,47%) presentaron IPP, y los pacientes tenían una edad promedio de presentación de 66 (±5,7) años, e índice de masa corporal (IMC) promedio de 30,3 (±4,5) kg/m2. La mediana de tiempo de presentación de la IPP fue de 411 (±1.034) días. Las principales comorbilidades registradas fueron hipertensión arterial en 5 (62,5%), tabaquismo en 4 (50%) casos, y dislipidemia in 4 (50%) casos. En total, 5 (62,5%) pacientes presentaron etiología polimicrobiana, y en 3 (37,5%) se aisló un solo microorganismo. Los principales agentes aislados fueron Staphylococcus aureus y Staphylococcus coagulasa negativo, ambos multirresistentes, en 6 (75%) y 3 (37,5%) pacientes respectivamente. Todos los pacientes recibieron tres dosis de cefazolina como profilaxis quirúrgica. Se describe una sensibilidad del 100% frente a vancomicina y rifampicina (12/12 cultivos), y una resistencia del 83,4% al ciprofloxacino (4/9 cultivos). Un total de 2 (25%) pacientes fallecieron después de 3 años de la ATR por causas no relacionadas con la IPP. No hubo casos de recidiva infecciosa tras la revisión. CONCLUSIÓN Se encontró una incidencia de 1,47% (8 casos) de IPP. Todos los pacientes con IPP presentaron alguna comorbilidad prequirúrgica. Los principales agentes microbiológicos identificados fueron multirresistentes y susceptibles a vancomicina y rifampicina.

INTRODUCTION Periprosthetic infection (PPI) is one of the most serious complications in total knee arthroplasty (TKA). Despite this, there is little Chilean literature regarding this pathology. OBJETIVES To determine the incidence, comorbidities, isolated microorganisms and their antibiotic susceptibility, morbidity, and mortality in patients with PPI. MATERIALS AND METHODS A descriptive and retrospective study in patients operated between 2001 and 2020 for gonarthrosis, with a primary TKA, in the same health center, with at least 1 year of follow-up. Patients operated on in other centers or with incomplete clinical records were excluded. Comorbidities, isolated microorganisms, antibiotic susceptibility, and survival were recorded through a systematic search of the clinical records of patients with PPI. Descriptive statistics were used to present the data. RESULTS We included 544 TKAs, 8 (1.47%) of which presented PPI, and the patients had an average age at presentation of 66 years ( 5.7 years) and an average body mass index (BMI) of 30.3 ( 4, 5) kg/m2 . The median time of presentation of the PPI was of 411 ( 1,034) days. The main comorbidities recorded were arterial hypertension in 5 (62.5%), smoking in 4 (50%) cases, and dyslipidemia in 4 (50%) cases. In total, 5 (62.5%) patients presented polymicrobial etiology, and in 3 (37.5%), a single microorganism was isolated. The main isolated agents were Staphylococcus aureus and coagulasenegative Staphylococcus, both multidrug-resistant, in 6 (75%) and 3 (37.5%) patients respectively. All patients received three doses of cefazolin as surgical prophylaxis. A sensitivity of 100% to vancomycin and rifampicin (12/12 cultures), and a resistance of 83.4% to ciprofloxacin (4/9 cultures) were described. Overall, 2 (25%) patients died 3 years after the TKA, due to causes unrelated to PPI. There were no cases of infectious relapse after the review. CONCLUSION An incidence of 1.47% (8 cases) of PPI was found. All patients with PPI presented some presurgical comorbidity. The main microbiological agents identified were multidrug-resistant and susceptible to vancomycin and rifampicin

Niveles de presión arterial en adultos indígenas Yanomami del Estado Amazonas, Venezuela / Blood pressure levels in Yanomami indigenous adults from the State of Amazonas, Venezuela

Introducción: Existen poblaciones que por razones aún no completamente estudiadas y comprendidas presentan niveles de presión arterial óptimos que determinan la ausencia de morbilidad y mortalidad relacionada con las afecciones cardiovasculares. Objetivo: Determinar los niveles de presión arterial de adultos indígenas Yanomami ubicados en la serranía de Topirapecó en el Estado Amazonas en Venezuela. Métodos: Entre los meses de mayo a julio y diciembre de 2021, se realizó un estudio cuantitativo transversal en 271 adultos indígenas Yanomami de 20 años de edad o más. Se visitó en 2 ocasiones cada shabono con la finalidad de realizarle medición de la presión arterial. Las orientaciones para cumplir con el protocolo de medición de presión arterial fueron impartidas en el idioma original de los Yanomami con el apoyo de un Agente Comunitario Yanomami de Atención Primaria de Salud. El análisis estadístico incluyó promedios, porcentajes e intervalos de confianza para promedios y para porcentajes. Resultados: El 93% de los individuos presentaron valores de presión arterial óptimos (<120 y <80) y 5,5% PA normal (<130 y <85). Solo se presentaron 2 casos (0,7%) con HTA (Grado I). Los niveles promedios de PAS, PAD y PAM fueron 93,10 (±11,70); 60,66 (±9,87) y 71,48 (±9,77) mm Hg, respectivamente. Conclusiones: Los Yanomami que viven en comunidades del área geográfica de la serranía de Tapirapecó presentan niveles óptimos de presión arterial, lo que les previene de comorbilidad asociada a la HTA, lo que indica que no constituye un problema de salud emergente entre los Yanomami (AU)

Public Programs for Essential Medicine Access in a Small Municipality: A Cross-Sectional Analysis

Abstract Background: Public programs that provide access to essential medications have played an important role in the care of hypertensive and diabetic patients. However, access in small municipalities has been poorly studied. Objectives: To describe the sociodemographic profile and the medication and health service usage of patients with systemic arterial hypertension and/or diabetes mellitus in a small municipality who use the public medication access programs Health has no Price (Saúde Não Tem Preço - SNTP) and the Minas Pharmacy Network. Methods: This cross-sectional study with 341 participants was conducted in 2019. Home interviews were conducted using a standardized, semi-structured questionnaire. The data are expressed as absolute and relative frequencies, and Pearson's chi-square test was used for comparisons between proportions (α = 5%). Results: Most of the participants (70.68%) had hypertension only, 11.14% had diabetes only, and 18.18% had both. Regarding the origin of the hypertension medications, 82.67% were provided by the Minas Pharmacy Network and/or SNTP programs. Regarding oral hypoglycemic agents and insulins, 88.61% were provided by the Minas Pharmacy Network and/or SNTP. Most participants were female (63.1%), at least 65 years of age (50.30%), non-White (66.96%), resided in an urban area (67.16%), were illiterate or had a low education level (89.94%), and had a maximum income ≤ 2 times the federal minimum salary (89.19%). Overall user perception was significantly better for SNTP (p=0.010). Conclusion: The results of this study indicate that programs which provide access to essential medications are important sources of hypertension and diabetes medications in the study area, especially for people with low incomes.

La dispensarización de pacientes hipertensos en el Policlínico Rafael Echezarreta / The classification of hypertensive patients at Rafael Echezarreta Polyclinic

Introducción: Uno de los principales problemas de salud que afectan a la población de Cuba y del mundo es la hipertensión arterial. En San José de Las Lajas aparece dispensarizada como hipertensa el 14 por ciento de su población, pero se observan múltiples deficiencias en su dispensarización. Objetivo: Determinar la situación de la dispensarización de las personas que padecen hipertensión arterial en los consultorios del médico y la enfermera de la familia del policlínico Rafael Echezarreta del municipio San José. Métodos: Se realizó una investigación descriptiva rápida de corte transversal, en enero de 2020. Se revisaron las historias clínicas individuales de una muestra de 379 pacientes hipertensos, que representaron el 11 por ciento de los 3446 hipertensos registrados en el policlínico. Resultados: Solo cerca del 20 por ciento de los hipertensos estaba dispensarizados. A excepción de los grupos de edades extremas, en el resto predominó el sexo femenino. Con el aumento de la edad aumentó la proporción de pacientes hipertensos. Ninguno de los pacientes tenía evidencia registrada en su historia clínica de haber sido atendido en los últimos cuatro meses y casi el 68 por ciento del total no había sido visto hacía más de un año. Conclusiones: La dispensarización mantiene insuficiencias que no garantizan atención médica integral a la población, no se cumple la frecuencia mínima de evaluación establecida para cada grupo dispensarial y el método clínico presenta fallas en su aplicación. Por lo que se puede afirmar que existe un número potencial de pacientes hipertensos aún sin controlar(AU)

Introduction: One of the main health problems that affect Cuban and worldwide population is high blood pressure. In San José de Las Lajas municipality, 14 percent of its population appears to be hypertensive, but there are multiple deficiencies in its classification. Objective: To determine the situation of the classification of people suffering from arterial hypertension in the Family Doctor´s Offices belonging to Rafael Echezarreta polyclinic, San José municipality. Methods: A rapid cross-sectional descriptive research was conducted in January 2020. The individual medical records (HCIs) of a sample of 379 hypertensive patients were reviewed, representing 11 percent of the 3446 hypertensive patients registered in the polyclinic. Results: Only about 20 percent of hypertensive patients were classified. With the exception of the extreme age groups, the female sex predominated in the rest. With increasing age, the proportion of hypertensive patients increased. None of the patients had evidence recorded in their medical records of having been attended in the last four months and almost 68 percent of the total had not been attended more than a year ago. Conclusions: The classification has insufficiencies that do not guarantee comprehensive medical care to the population, the minimum frequency of evaluation established for each classification group is not met and the clinical method presents failures in its application. So it can be said that there is a potential number of hypertensive patients still uncontrolled(AU)
