Risk factors for acute kidney injury in patients hospitalized with COVID-19 / Fatores de risco para lesão renal aguda em pacientes hospitalizados com COVID-19

Abstract Introduction: Acute kidney injury (AKI) occurs frequently in COVID-19 patients and is associated with greater morbidity and mortality. Knowing the risks of AKI allows for identification, prevention, and timely treatment. This study aimed to identify the risk factors associated with AKI in hospitalized patients. Methods: A descriptive, retrospective, cross-sectional, and analytical component study of adult patients hospitalized with COVID-19 from March 1 to December 31, 2020 was carried out. AKI was defined by the creatinine criteria of the KDIGO-AKI guidelines. Information, regarding risk factors, was obtained from electronic medical records. Results: Out of the 934 patients, 42.93% developed AKI, 60.59% KDIGO-1, and 9.9% required renal replacement therapy. Patients with AKI had longer hospital stay, higher mortality, and required more intensive care unit (ICU) admission, mechanical ventilation, and vasopressor support. Multivariate analysis showed that age (OR 1.03; 95% CI 1.02-1.04), male sex (OR 2.13; 95% CI 1.49-3.04), diabetes mellitus (DM) (OR 1.55; 95% CI 1.04-2.32), chronic kidney disease (CKD) (OR 2.07; 95% CI 1.06-4.04), C-reactive protein (CRP) (OR 1.02; 95% CI 1.00-1.03), ICU admission (OR 1.81; 95% CI 1.04-3.16), and vasopressor support (OR 7.46; 95% CI 3.34-16.64) were risk factors for AKI, and that bicarbonate (OR 0.89; 95% CI 0.84-0.94) and partial pressure arterial oxygen/inspired oxygen fraction index (OR 0.99; 95% CI 0.98-0.99) could be protective factors. Conclusions: A high frequency of AKI was documented in COVID-19 patients, with several predictors: age, male sex, DM, CKD, CRP, ICU admission, and vasopressor support. AKI occurred more frequently in patients with higher disease severity and was associated with higher mortality and worse outcomes.

RESUMO Introdução: Lesão renal aguda (LRA) ocorre frequentemente em pacientes com COVID-19 e associa-se a maior morbidade e mortalidade. Conhecer riscos da LRA permite a identificação, prevenção e tratamento oportuno. Este estudo teve como objetivo identificar fatores de risco associados à LRA em pacientes hospitalizados. Métodos: Realizou-se estudo descritivo, retrospectivo, transversal e de componente analítico de pacientes adultos hospitalizados com COVID-19 de 1º de março a 31 de dezembro, 2020. Definiu-se a LRA pelos critérios de creatinina das diretrizes KDIGO-LRA. Informações sobre fatores de risco foram obtidas de prontuários eletrônicos. Resultados: Dos 934 pacientes, 42,93% desenvolveram LRA, 60,59% KDIGO-1 e 9,9% necessitaram de terapia renal substitutiva. Pacientes com LRA apresentaram maior tempo de internação, maior mortalidade e necessitaram de mais internações em UTIs, ventilação mecânica e suporte vasopressor. A análise multivariada mostrou que idade (OR 1,03; IC 95% 1,02-1,04), sexo masculino (OR 2,13; IC 95% 1,49-3,04), diabetes mellitus (DM) (OR 1,55; IC 95% 1,04-2,32), doença renal crônica (DRC) (OR 2,07; IC 95% 1,06-4,04), proteína C reativa (PCR) (OR 1,02; IC 95% 1,00-1,03), admissão em UTI (OR 1,81; IC 95% 1,04-3,16) e suporte vasopressor (OR 7,46; IC 95% 3,34-16,64) foram fatores de risco para LRA, e que bicarbonato (OR 0,89; IC 95% 0,84-0,94) e índice de pressão parcial de oxigênio arterial/fração inspirada de oxigênio (OR 0,99; IC 95% 0,98-0,99) poderiam ser fatores de proteção. Conclusões: Documentou-se alta frequência de LRA em pacientes com COVID-19, com diversos preditores: idade, sexo masculino, DM, DRC, PCR, admissão em UTI e suporte vasopressor. LRA ocorreu mais frequentemente em pacientes com maior gravidade da doença e associou-se a maior mortalidade e piores desfechos.

Falta de conhecimento sobre os fatores de risco não ocupacionais da dor lombar entre profissionais de saúde ocupacional brasileiros: um estudo observacional transversal / Lack of knowledge about non-occupational low back pain risk factors among brazilian occupational health professionals: a cross-sectional observational study

INTRODUÇÃO: A dor lombar possui alta prevalência, sendo uma das principais causas de incapacidade no Brasil e no mundo. A dor lombar apresenta etiologia multifatorial, sendo extremamente comum em trabalhadores. OBJETIVOS: Verificar o conhecimento sobre os fatores de risco para dor lombar, crenças e atitudes sobre o manejo da dor lombar entre profissionais de saúde (fisioterapeutas e ergonomistas) atuantes na área ocupacional. MATERIAIS E MÉTODOS: Foi realizado um estudo observacional transversal com 81 profissionais de saúde ocupacional brasileiros. Os participantes preencheram um questionário eletrônico composto por dados profissionais, sociodemográficos, itens sobre fatores de risco para dor lombar e a Brazilian version of the Pain Attitudes and Beliefs Scale for Physiotherapists. Conhecimentos, crenças e atitudes foram analisados por meio do teste do qui-quadrado para fatores de risco para dor lombar e um modelo de regressão linear para crenças e atitudes dos profissionais de saúde. RESULTADOS: Obesidade (7,4%), ficar sentado mais de 2 horas (8,6%), atividade física (9,9%), falta de apoio psicossocial no trabalho (11,1%) e consumo de álcool (37,0%), apresentaram os menores índices de conhecimento sobre fatores de risco da dor lombar pelos profissionais. Itens sobre saúde geral apresentaram o menor conhecimento. Uma orientação biomédica e psicossocial equilibrada de crenças e atitudes sobre o manejo da dor lombar foi observada. CONCLUSÃO: Profissionais de saúde ocupacional brasileiros carecem de conhecimento sobre os fatores de risco não ocupacionais da dor lombar, especialmente o estado geral de saúde. Esses profissionais também possuem conceitos biomédicos e psicossociais equilibrados no manejo da dor lombar.

INTRODUCTION: Low back pain (LBP) is highly prevalent and is one of the main causes of disability in Brazil and around the world. LBP presents a multifactorial etiology, being extremely common in workers. OBJECTIVE: This study aimed to verify the knowledge about the LBP risk factors, beliefs and attitudes about the management of LBP among health professionals (physiotherapists and ergonomists) working in the occupational area. MATERIALS AND METHODS: A cross-sectional observational study was conducted with 81 Brazilian occupational health professionals. Participants completed an electronic questionnaire comprising professional data, sociodemographics, items about LBP risk factors, and the Brazilian version of the Pain Attitudes and Beliefs Scale for Physiotherapists. Knowledge, beliefs and attitudes were analyzed using the chi-square test for LBP risk factors and the linear regression model for health professionals' beliefs and attitudes. RESULTS: Obesity (7.4%), sitting for more than 2 hours (8.6%), physical activity (9.9%), lack of psychosocial support at work (11.1%) and consuming alcohol (37.0%) presented the lowest rate of knowledge about LBP risk factors by professionals. Items about general health showed the lowest knowledge. A balanced biomedical and psychosocial orientation of beliefs and attitudes about managing LBP was observed. CONCLUSION: Brazilian occupational health professionals lack knowledge about non-occupational LBP risk factors, especially general health status. These professionals also have balanced biomedical and psychosocial concepts in managing LBP.

Efecto del confinamiento por COVID-19 en la prevalencia de la enfermedad hepática esteatósica asociada a disfunción metabólica / Effect of COVID-19 lockdown on the prevalence of metabolic dysfunction-associated steatotic liver disease

Introducción. La enfermedad hepática esteatósica asociada a disfunción metabólica (MASLD) es una condición clínica frecuente, relacionada con el sobrepeso, la dislipidemia y la diabetes. Como estos factores de riesgo están a su vez asociados al sedentarismo y la ganancia de peso, se esperaría un impacto como resultado del confinamiento por COVID-19 en la prevalencia de dicha condición. Metodología. Estudio longitudinal retrospectivo en un panel de datos de 132 pacientes de 2017 a 2022, en donde fueron incluidos pacientes con una ecografía hepática y una valoración médica y paraclínica 1,5 años antes y después del periodo de confinamiento (25 de marzo de 2020 a 28 de febrero de 2021). El desenlace primario fue un cambio significativo en la prevalencia de la MASLD, y se utilizó un modelo exploratorio de regresión logística de efectos fijos con panel de datos para hallar los predictores de cambio. Resultados. En un total de 132 pacientes analizados, la prevalencia global de la MASLD antes (31 %; IC95%: 23-39) y después (35,6 %; IC95%: 27,4-43,8) del confinamiento por COVID-19 no cambió significativamente, sin embargo, en las mujeres sí hubo un aumento significativo (RR: 4; IC95%: 1,0004-16). Se encontró una marcada diferencia de prevalencia entre sexos (17 % en mujeres y 46 % en hombres; p=0,001). El confinamiento se asoció a incrementos en la masa corporal (diferencia: +1 kg; IC95%: 0,1-1,9), el colesterol LDL (diferencia: +9,7 mg/dL; IC95%: 4,9-14,4) y al diagnóstico de prediabetes (RR: 2,1; IC95%: 1,4-3,1). La MASLD se asoció positivamente a la preferencia nutricional por la comida rápida (p=0,047). Solo el índice de masa corporal resultó predictor independiente de MASLD (RR: 1,49; IC95%: 1,07-1,93). Conclusión. La prevalencia global de la MASLD no varió después del confinamiento por COVID-19, pero sí se incrementó en mujeres, y algunos de sus factores de riesgo también aumentaron significativamente. Se encontró equivalencia numérica entre la MASLD y la definición previa de la enfermedad. Se requiere un estudio local más grande para desarrollar y validar un mejor modelo predictor del cambio de la MASLD a través del tiempo.

Introduction. Metabolic dysfunction-associated steatotic liver disease (MASLD) is a common clinical condition, related to overweight, dyslipidemia and diabetes. As these risk factors are in turn associated with sedentary lifestyle and weight gain, an impact as a result of the COVID-19 confinement on the prevalence of MASLD would be expected. Methodology. Retrospective longitudinal study in a data panel of 132 patients from 2017 to 2022. Patients with a liver ultrasound and a medical and paraclinical assessment 1.5 years before and after the confinement period (March 25, 2020 to February 28, 2021) were included. The primary outcome was a significant change in the prevalence of MASLD, and an exploratory fixed-effects logistic regression model with panel data was used to find predictors of change. Results. In a total of 132 patients analyzed, the overall prevalence of MASLD before (31%, 95%CI: 23-39) and after (35.6%, 95%CI: 27.4-43.8) confinement by COVID-19 did not change significantly, however, in women there was a significant increase (RR: 4, 95%CI: 1.0004-16). A marked difference in prevalence was found between sexes (17% in women and 46% in men; p=0.001). Confinement was associated with increases in body mass (difference: +1 kg, 95%CI: 0.1-1.9), LDL cholesterol (difference: +9.7 mg/dL, 95%CI: 4.9-14.4) and the diagnosis of prediabetes (RR: 2.1, 95%CI: 1.4-3.1). MASLD was positively associated with nutritional preference for fast food (p=0.047). Only body mass index was an independent predictor of MASLD (RR: 1.49, 95%CI: 1.07-1.93). Conclusion. The overall prevalence of MASLD did not change after the COVID-19 lockdown, but it did increase in women, and some of its risk factors also increased significantly. Numerical equivalence was found between MASLD and the previous definition of the disease. A larger local study is required to develop and validate a better predictor model of MASLD change over time.

Assessment of risk factors for leakage after repair of perforated peptic ulcer with omental patch. Retrospective study / Evaluación de factores de riesgo de fuga después de la reparación de una úlcera péptica perforada con parche de epiplón. Estudio retrospectivo

Introduction. Perforated peptic ulcer remains one of the critical abdominal conditions that requires early surgical intervention. Leakage after omental patch repair represents one of the devastating complications that increase morbidity and mortality. Our study aimed to assess risk factors and early predictors for incidence of leakage. Methods. Retrospective analysis of data of the patients who underwent omental patch repair for perforated peptic ulcer in the period between January 2019 and January 2022 in Mansoura University Hospital, Egypt. Pre, intra and postoperative variables were collected and statistically analyzed. Incriminated risk factors for leakage incidence were analyzed using univariate and multivariate analysis. Results. This study included 123 patients who met inclusion criteria. Leakage was detected in seven (5.7%) patients. Although associated comorbidities (p=0.01), postoperative intensive care unit admission (p=0.03), and postoperative hypotension (p=0.02) were significant risk factors in univariate analysis, septic shock (p=0.001), delayed intervention (p=0.04), preoperative hypoalbuminemia (p=0.017), and perforation size >5mm (p= 0.04) were found as independent risk factors for leakage upon multivariate analysis. Conclusion. Delayed presentation in septic shock, preoperative hypoalbuminemia, prolonged perforation, operation interval, and large perforation size > 5mm were detected as independent risk factors for leakage. Postoperative tachypnea and tachycardia with increased levels of C-reactive protein and total leucocytic count are alarming signs for incidence of leakage

Introducción. La úlcera péptica perforada es una de las afecciones abdominales críticas que requiere una intervención quirúrgica temprana. La fuga después de la reparación con parche de epiplón representa una de las complicaciones más devastadoras, que aumentan la morbilidad y la mortalidad. Nuestro estudio tuvo como objetivo evaluar los factores de riesgo y los predictores tempranos de fugas. Métodos. Análisis retrospectivo de los datos de los pacientes sometidos a reparación con parche de epiplón por úlcera péptica perforada, en el período comprendido entre enero de 2019 y enero de 2022, en el Hospital Universitario de Mansoura, Egipto. Se recogieron y analizaron estadísticamente variables pre, intra y postoperatorias. Los factores de riesgo asociados a la incidencia de fugas se analizaron mediante análisis univariado y multivariado. Resultados. Este estudio incluyó 123 pacientes que cumplieron con los criterios de inclusión. Se detectó fuga en siete (5,7 %) pacientes. Aunque las comorbilidades asociadas (p=0,01), el ingreso postoperatorio a la unidad de cuidados intensivos (p=0,03) y la hipotensión postoperatoria (p=0,02) fueron factores de riesgo en el análisis univariado, el shock séptico (p=0,001), el retraso en la intervención (p=0,04), la hipoalbuminemia preoperatoria (p=0,017) y el tamaño de la perforación mayor de 5 mm (p=0,04) se encontraron como factores de riesgo de fuga independientes en el análisis multivariado. Conclusión. Se detectaron como factores de riesgo independientes de fuga la presentación tardía en shock séptico, la hipoalbuminemia preoperatoria, la perforación prolongada, el intervalo operatorio y el tamaño de la perforación mayor de 5 mm. La taquipnea posoperatoria y la taquicardia con niveles elevados de proteína C reactiva y recuento leucocitario total son signos de alarma sobre la presencia de fuga.

Incidence of radiodermatitis and factors associated with its severity in women with breast cancer: a cohort study

Abstract Background: One of the main adverse reactions of adjuvant radiotherapy for breast cancer is radiodermatitis. Objective: To assess the incidence of radiodermatitis in women with breast cancer, identify factors associated with its severity and determine the time at which this event occurs. Methods: Prospective cohort study in 113 women with breast cancer who were evaluated before radiotherapy and at every fifth session until the end of treatment. Logistic regression and Cox proportional regression model were used for the assessment of risk factors; P values < 0.05 were considered significant. Results: The incidence rate of radiodermatitis was 98.2% and it was demonstrated that for each additional point of the Body Mass Index (BMI), the chance of occurrence of grades II to IV radiodermatitis increases by 14% (OR = 1.14 [95% CI 1.04-1.26]; p = 0.004) and statin use increases the risk of more severe skin lesions by four-fold (OR = 4.27 [95% CI 1.11-16.42]; p = 0.035). The exclusive use of hydrogel for skin hydration was an independent factor in delaying the onset of radiodermatitis (HR = 0.55 [95% CI 0.36-0.82]; p = 0.004). Study limitations: The main limitation of this study was its external validity. The identified factors should be considered for services and populations similar to those in this study. Conclusions: There was a high incidence of radiodermatitis and its severity was related to higher BMI, statin use; there was a protective effect of hydrogel use.

Risk factors for postoperative pulmonary infection in lung cancer patients: A systematic review and meta-analysis / 中国胸心血管外科临床杂志

@#Objective    To systematically evaluate the risk factors for postoperative pulmonary infection in patients with lung cancer (PPILC), and to provide a theoretical reference for clinicians to prevent the occurrence of PPILC. Methods     The databases of CNKI, Wanfang data, VIP, CBM, PubMed, EMbase and The Cochrane Library were searched by computer to collect researches on the risk factors for PPILC. The search period was from 2012 to 2021. Two clinicians independently screened literature and extracted data and assessed studies for risk of bias, cross-checked and agreed. Meta-analysis was performed using RevMan 5.3 software. Results     A total of 25 studies were included, including 20 case-control studies, 1 cohort study, and 4 cross-sectional studies, covering 15 129 patients. Twenty case-control studies and 1 cohort study had Newcastle-Ottawa Scale (NOS) scores≥6 points, and 4 cross-sectional studies had the Agency for Health Care Quality and Research (AHRQ) scale scores≥6 points. The results of meta-analysis showed that the risk factors for PPILC included: (1) 4 patient's own factors: age≥60 years, male, smoking history, smoking index≥400; (2) 7 preoperative factors: suffering from diabetes, chronic heart failure and chronic obstructive pulmonary disease, the ratio of forced expiratory volume in 1 second to forced expiratory volume<70%, the ratio of forced expiratory volume in 1 second to the predicted value, preoperative airway colonization, non-standard use of prophylactic antibiotics before surgery; (3) 3 intraoperative factors: operation time≥3 h, thoracotomy, the number of resected lobe≥2; (4) 3 postoperative factors: postoperative pain, postoperative mechanical ventilation≥12 h, postoperative invasive operation. Large number of preoperative lymphocyte, intraoperative systematic lymph node dissection, TNM stage Ⅰ and Ⅱ, and enhanced recovery after surgery were protective factors for PPILC. Conclusion     The current research evidence shows that multiple factors are associated with the risk of PPILC. However, considering the influence of the quality and quantity of the included literature, the results of this study urgently need to be further verified by more high-quality clinical studies.

Analysis on risk factors of clopidogrel resistance in patients with ischemic stroke / 药学实践杂志

Objective To investigate the risk factors of drug resistance in patients with ischemic stroke by clopidogrel therapy and provide references for promoting clinical individualized drug therapy. Methods A total of 202 inpatients diagnosed with ischemic stroke were admitted and given dual anti-treatment (aspirin+clopidogrel). CYP2C19 genotype was detected by microarray hybridization during hospitalization, and CYP2C19 gene polymorphisms were classified into fast metabolism group, medium metabolism group and slow metabolism group according to the type of drug metabolism. Patients were tested for platelet inhibition induced by adenosine diphosphate (ADP) according to thromboelastographic (TEG) on 7~14 d of drug administration. ADP <30% was classified as clopidogrel drug resistance group and ADP ≥30% as non-resistance group. Logistic regression analysis was used to study the risk factors for the development of clopidogrel resistance. Results Among 202 patients with ischemic stroke, 87 were in the resistant group and 115 in the non-resistant group. The proportion of patients with clopidogrel resistance combined with diabetes and the level of white blood cell count were higher than that in the non-resistant group, and the differences were statistically significant (P<0.05).The proportion of patients with clopidogrel resistance in the CYP2C19 intermediate metabolism group was significantly higher than that in the fast metabolism group, and the rate of platelet inhibition was also significantly lower than that in the fast metabolism group, all with statistically significant differences (P<0.05). Conclusion Combined diabetes mellitus, high white blood cell count levels and CYP2C19 mid-metabolic phenotype are independent risk factors for the development of clopidogrel resistance in patients with ischemic stroke.

Construction of a risk prediction model for bloodstream infection induced by carbapenem-resistant Klebsiella pneumoniae / 中国药房

OBJECTIVE To construct a risk prediction model for bloodstream infection （BSI） induced by carbapenem-resistant Klebsiella pneumoniae （CRKP）. METHODS Retrospective analysis was conducted for clinical data from 253 patients with BSI induced by K. pneumoniae in the First Hospital of Qinhuangdao from January 2019 to June 2022. Patients admitted from January 2019 to December 2021 were selected as the model group （n＝223）， and patients admitted from January 2022 to June 2022 were selected as the validation group （n＝30）. The model group was divided into the CRKP subgroup （n＝56） and the carbapenem- sensitive K. pneumoniae （CSKP） subgroup （n＝167） based on whether CRKP was detected or not. The univariate and multivariate Logistic analyses were performed on basic information such as gender， age and comorbid underlying diseases in two subgroups of patients； independent risk factors were screened for CRKP-induced BSI， and a risk prediction model was constructed. The established model was verified with patients in the validation group as the target. RESULTS Admissioning to intensive care unit （ICU）， use of immunosuppressants， empirical use of carbapenems and empirical use of antibiotics against Gram-positive coccus were independent risk factors of CRKP-induced BSI （ORs were 3.749， 3.074， 2.909， 9.419， 95%CIs were 1.639-8.572， 1.292- 7.312， 1.180-7.717， 2.877-30.840， P＜0.05）. Based on this， a risk prediction model was established with a P value of 0.365. The AUC of the receiver operating characteristic （ROC） curve of the model was 0.848 [95%CI （0.779， 0.916）， P＜0.001]， and the critical score was 6.5. In the validation group， the overall accuracy of the prediction under the model was 86.67%， and the AUC of ROC curve was 0.926 [95%CI （0.809， 1.000]， P＜0.001]. CONCLUSIONS Admission to ICU， use of immunosuppressants， empirical use of carbapenems and empirical use of antibiotics against Gram-positive coccus are independent risk factors of CRKP- induced BSI. The CRKP-induced BSI risk prediction model based on the above factors has good prediction accuracy.

Influencing factors of telangiectasia secondary to diabetic retinopathy / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To investigate the influencing factors of abnormal telangiectasia secondary to diabetic retinopathy(DR).METHODS: Prospective studies. A total of 153 cases(240 eyes)with DR treated in our hospital from January 2021 to January 2023 were selected to analyze the risk factors of abnormal telangiectasia secondary to DR and its predictive efficacy.RESULTS: The patients were divided into dilated group(77 eyes of 40 cases)and non-dilated group(163 eyes of 113 cases)according to whether they had secondary abnormal telangiectasia. There were significant differences in diabetic macular edema, hard exudates grade and fasting blood glucose level between the two groups(P&#x0026;#x003C;0.05). Logistic regression analysis showed that diabetic macular edema, high hard exudates grade and high blood glucose level were the risk factors for abnormal telangiectasia secondary to DR(P&#x0026;#x003C;0.05).CONCLUSION: The occurrence of telangiectasia secondary to DR may be related to diabetic macular edema, grade 3 hard exudates and high blood glucose level.

Research progress of mechanism and risk factors of retinal vein occlusion / 国际眼科杂志(Guoji Yanke Zazhi)

Retinal vein occlusion(RVO), the second most prevalent retinal vascular disease, has complex pathophysiological mechanism. Except for mechanical pressure on blood vessel, inflammation and endothelin have been confirmed to be involved in the pathogenesis of RVO. However, its specific mechanism remains unclear. Hypertension, diabetes and dyslipidemia have been previously shown to be the most common risk factors in elder population, while recent studies found that coagulation and hemorheological abnormalities are more common in people under 50 years old. Ocular risk factors including glaucoma, high corrected intraocular pressure and retinal vessels abnormality, have gained more and more attention. These factors probably exert a synergistic effect when present simultaneously in the same patient. Therefore, early identification and intervention of those factors could lower the incidence of RVO. This article aims to review recent research and summarize existing mechanism and theories, giving some new research ideas for potential therapy targets and providing references for identification and management of risk factors.

El puntaje de Framingham ayudaría en la estratificación del riesgo de pacientes con ergometría positiva y SPECT normal / The Framingham score could help in risk stratification of patients with positive ergometry and normal SPECT

Antecedentes. El valor pronóstico de una ergometría positiva en el contexto de imágenes tomográficas de perfusión miocárdica de estrés y reposo (SPECT) normales no está bien establecido. Objetivos. Documentar la incidencia de infarto, muerte y revascularización coronaria en pacientes con una ergometría positiva de riesgo intermedio e imágenes de perfusión SPECT normales, y explorar el potencial valor del puntaje de riesgo de Framingham en la estratificación pronóstica de estos pacientes. Métodos. Cohorte retrospectiva integrada por pacientes que habían presentado síntomas o hallazgos electrocardiográficos compatibles con enfermedad arterial coronaria durante la prueba de esfuerzo, con criterios de riesgo intermedio en la puntuación de Duke y perfusión miocárdica SPECT normal. Fueron identificados a partir de la base de datos del laboratorio de cardiología nuclear del Instituto de Cardiología y Cirugía Cardiovascular de la ciudad de Posadas, Argentina. Resultados. Fueron elegibles 217 pacientes. El seguimiento fue de 3 1,5 años. La sobrevida libre de eventos (muerte,infarto de miocardio no fatal, angioplastia coronaria o cirugía de bypass de arteria coronaria) a uno, tres y cinco años fue significativamente menor (Log-rank test, p= 0,001) en el grupo con puntaje de Framingham alto o muy alto (77, 71y 59 %, respectivamente) que en el grupo de puntaje bajo o intermedio (89, 87 y 83 %). Tomando como referencia a los pacientes con riesgo bajo en el puntaje de Framingham, luego de ajustar por edad, sexo y puntaje de Duke, los pacientes categorizados en los estratos alto y muy alto riesgo del puntaje de Framingham presentaron una incidencia del evento combinado cercana al triple (hazard ratio [HR] 2,81; intervalo de confianza [IC] del 95 % 0,91 a 8,72; p= 0,07 y HR 3,61;IC 95 % 1,23 a 10,56; p= 0,019 respectivamente). Conclusiones. La estimación de riesgo con el puntaje de Framingham sería de ayuda en la estratificación pronóstica de los pacientes con ergometría positiva y SPECT normal. (AU)

Background. The prognostic value of positive exercise testing with normal SPECT myocardial perfusion imaging is not well established. Objectives. To document the incidence of infarction, death, and coronary revascularization in patients with a positive intermediate-risk exercise test and normal SPECT perfusion images and to explore the potential value of the Framingham Risk Score in the prognostic stratification of these patients. Methods. A retrospective cohort comprised patients who presented symptoms or electrocardiographic findings compatible with coronary artery disease during the stress test, with intermediate risk criteria in the Duke score and normal SPECT myocardial perfusion. They were identified from the database of the nuclear cardiology laboratory of the Instituto de Cardiología y Cirugía Cardiovascular of Posadas, Argentina. Results. 217 patients were eligible. Follow-up was 3 1.5 years. Event-free survival (death, non-fatal myocardial infarction, coronary angioplasty, or coronary artery bypass surgery) at one, three, and five years was significantly lower (Log-ranktest, p: 0.001) in the group with a score of Framingham high or very high (77, 71 and 59 %, respectively) than in the lowor intermediate score group (89, 87 and 83 %). Taking as reference the low-risk patients in the Framingham score, after adjusting for age, sex, and Duke score, the patients categorized in the high-risk and very high-risk strata showed about three times higher incidence of the combined event (hazard ratio [HR] 2.81; 95 % confidence interval [CI] 0.91 to 8.72;p=0.07 and HR 3.61; 95 % CI 1.23 to 10.56; p=0.019 respectively). Conclusions. Risk estimation with the Framingham score would be helpful in the prognostic stratification of patients with positive exercise testing and normal SPECT. (AU)

Impacts caused by the use of screens during the COVID-19 pandemic in children and adolescents: an integrative review / Impactos causados pelo uso de telas durante a pandemia da COVID-19 em crianças e adolescentes: uma revisão integrativa

ABSTRACT Objective: To identify the scientific evidence on the impacts caused by the use of screens during the COVID-19 pandemic in children and adolescents, raising reflections for future interventions with this public. Data source: This is an integrative literature review, conducted in the databases Medical Literature Analysis and Retrieval System Online (MEDLINE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Cumulative Index to Nursing and Allied Health Literature (CINAHL), United States National Library of Medicine (PubMed), Scopus, Web of Science, and Embase, published from March 2020 to January 2022, in Portuguese, English and Spanish. Data synthesis: The search strategies allowed retrieving 418 articles, of which 218 were duplicates. The analysis of titles and abstracts resulted in the maintenance of 62 studies. Of these, 31 were excluded from the reading of the full text, since they did not clearly present the phenomenon investigated. Thirty-one were eligible, resulting in five categories: eye consequences; increased sedentary behavior and weight; change in eating habits; implications for sleep quality and impacts on mental health. Conclusions: The excessive use of screens during the pandemic led to numerous consequences for children and adolescents, with a higher incidence of visual damage, sedentary lifestyle, inadequate eating habit and increased weight gain, in addition to impaired sleep quality and mental health. This study provides subsidy for health professionals to carry out continuing education focused on this theme, and elaborate effective interventions for this public in this transition to the post-pandemic period.

RESUMO Objetivo: Identificar as evidências científicas sobre os impactos causados pelo uso de telas durante a pandemia da COVID-19 em crianças e adolescentes, almejando reflexões para futuras intervenções com esse público. Fontes de dados: Trata-se de uma revisão integrativa da literatura, realizada nas bases de dados Medical Literature Analysis and Retrieval System Online (MEDLINE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Cumulative Index to Nursing and Allied Health Literature (CINAHL), United States National Library of Medicine (PubMed), Scopus, Web of Science e Embase, publicados de março de 2020 a janeiro de 2022, em português, inglês e espanhol. Síntese dos dados: As estratégias de busca possibilitaram recuperar 418 artigos, sendo 218 duplicados. A análise de títulos e resumos resultou na manutenção de 62 estudos. Destes, após a leitura do texto integral foram excluídos 31, uma vez que não apresentavam com clareza o fenômeno investigado. Foram elegíveis 31 estudos, emergindo cinco categorias: consequências oculares; aumento do comportamento sedentário e do peso; alteração dos hábitos alimentares; implicações na qualidade do sono e impactos na saúde mental. Conclusões: Percebe-se que o uso telas em excesso durante a pandemia trouxe inúmeras consequências para o público infantojuvenil, com maior incidência de acometimentos visuais, sedentarismo, alimentação inadequada e, por consequência, maior ganho de peso, além de prejuízos à qualidade do sono e à saúde mental. Este estudo fornece subsídios para que os profissionais da saúde realizem educação continuada voltada para essa temática e elaborem intervenções efetivas para esse público nesta transição para o período pós-pandêmico.

Las herramientas predictivas de riesgo, una alternativa diagnóstica en la retención de caninos maxilares

Se describen, en la literatura médica, predictores radiográficos que constituyen herramientas diagnósticas útiles para la retención de los caninos maxilares. Sin embargo, en la especialidad de ortodoncia las investigaciones sobre las herramientas predictivas de riesgo son escasas. Por ello se decide realizar una revisión bibliográfica con el objetivo de recopilar información acerca de la utilidad de las herramientas predictivas de riesgo en el diagnóstico de la retención de los caninos maxilares. Se realizó una búsqueda de información de artículos en idioma español e inglés, utilizándose las bases de datos SciELO, PubMed, Cochrane y Scopus. Para lograr un tratamiento óptimo de la anomalía debe priorizarse un buen diagnóstico, basado en métodos clínicos y radiográficos, pero se hace notoria la ausencia de herramientas que identifiquen individuos con alto riesgo en la comunidad. Los modelos o escalas de riesgo pueden ser útiles en este aspecto, para detectar precozmente el trastorno eruptivo y priorizar así intervenciones preventivas, que eviten el uso excesivo de medios auxiliares de diagnóstico y la sobrecarga de los sistemas de salud. Las herramientas predictivas de riesgo constituyen una alternativa para la clasificación adecuada de la población con alto riesgo de retención de caninos maxilares. Un instrumento de tal magnitud es de gran utilidad tanto en los servicios de Estomatología General como en los de Ortodoncia.

Radiographic predictors that are useful diagnostic tools for the retention of maxillary canines are described in the literature. However, in the specialty of orthodontics, research on risk predictive tools is scarce. Therefore, it was decided to carry out a bibliographic review with the objective of collecting information about the usefulness of risk predictive tools in the diagnosis of retention of maxillary canines. A search for information on articles in Spanish and English was carried out, using the SciELO, PubMed, Cochrane and Scopus databases. To achieve optimal treatment of the anomaly, a good diagnosis should be prioritized, based on clinical and radiographic methods, but the absence of tools that identify individuals at high risk in the community is notorious. Models or risk scales can be useful in this aspect, to detect the eruptive disorder early and thus prioritize preventive interventions that avoid the excessive use of diagnostic aids and the overload of health systems. Predictive risk tools are an alternative for the adequate classification of the population with high risk of retention of maxillary canines. An instrument of this magnitude is very useful both in General Dentistry and Orthodontics services.

Asociación del riesgo a desarrollar diabetes mellitus tipo 2 según la calculadora de la asociación americana de diabetes (ADA) y los hábitos tóxicos no ilícitos en pacientes que residen en una comunidad rural de Peravia, República Dominicana / Association of the risk of developing type 2 diabetes mellitus according to the American Diabetes Association (ADA) calculator and non-illicit toxic habits in patients residing in a rural community in Peravia, Dominican Republic

Introducción: la diabetes mellitus tipo 2 (DM2) se define como un trastorno metabólico caracterizado por niveles de glucosa en sangre crónicamente elevados. La DM2 representa el paradigma de las enfermedades crónicas en las que existe una estrecha asociación entre factores familiares y ambientales. Por este motivo, este estudio tiene como finalidad determinar la asociación del riesgo a desarrollar DM2 y los hábitos tóxicos no ilícitos en pacientes que residen en una comunidad rural de Peravia, República Dominicana. Tales incluyen: alcohol, café y té. Metodología: Estudio observacional, transversal, analítico y prospectivo. Se aplicó cuestionario, recolectaron datos antropométricos y se determinó glucosa capilar a la muestra (n=304). Resultados: la prevalencia a presentar un alto riesgo a desarrollar DM2 en la población es de 35.5%, mientras que la prevalencia a presentar riesgo bajo es de 64.5%. En cuanto a hábitos tóxicos, no existió correlación positiva entre consumo de té y desarrollo de DM2. Sin embargo, sí entre el consumo de café y alcohol. Conclusiones: los habitantes de salinas presentan un bajo riesgo a desarrollar DM2, pero utilizan factores de riesgos modificables que aumentan la prevalencia a DM2.

Introduction: Type 2 diabetes mellitus (DM2) is defined as a metabolic disorder characterized by chronically elevated blood glucose levels. DM2 represents the paradigm of chronic diseases in which there is a close association between family and environmental factors. Therefore, the purpose of this study is to determine the association of the risk of developing DM2 and non-illicit toxic habits in patients residing in a rural community in Peravia, Dominican Republic. Such habits include alcohol, coffee and tea. Methodology: Observational, cross-sectional, analytical and prospective study. A questionnaire was applied, anthropometric data was collected, and capillary glucose was determined in the study sample (n=304). Results: the prevalence of presenting a high risk of developing DM2 in the population is 35.5%, while the prevalence of presenting low risk is 64.5%. Regarding toxic habits, there was no positive correlation between tea consumption and the development of DM2. However, this result differed between consumption of coffee and alcohol. Conclusions: the inhabitants of Salinas have a low risk of developing DM2 but are subject to modifiable risk factors that increase said prevalence.

Abstract Objective To identify the prevalence of the use of legal and illicit drugs by pregnant women who received prenatal care in Primary Health Care and factors associated with their usage. Methods Cross-sectional study carried out using a structured script, composed of gestational sociodemographic variables and drug use by pregnant women and their families, applied to 270 women undergoing low-risk prenatal care at 15 Basic Health Units, in two municipalities in a metropolitan region of Southern Brazil, where there are negative socioeconomic and demographic differences in relation to the hub city. Data collection took place from December 2019 to February 2020. Data were analyzed using Pearson's chi-square test, with associations with a value of p<0.05 being considered significant. Results Young people aged 25 to 35 accounted for 77% of the sample; brown/black were 60.4%; multigravidae accounted for 41.8% (with more than three children). 86.6% had a steady marital partner. The prevalence of current drug use was 46.2%. There was a statistically significant association between alcohol consumption and having had pregnancy complications (odds ratio of 2.5; confidence interval of 1.17-5.22); between marijuana consumption and the age of 15 to 19 years (odds ratio of 2.7; confidence interval of 1.01-7.03); between tobacco consumption and drug use by the husband (odds ratio of 4.1; confidence interval of 1.75-9.55) and between tobacco use and single-parent family classification (odds ratio of 6.6 ; confidence interval 1.55 - 28.43). Conclusion The prevalence between current usage and lifetime use was high. The multipregnancies in women were undergoing low-risk prenatal care. Drug use, age, drug use by the husband and single-parent family classification were associated with gestational complications.

Factores de riesgo asociados al agravamiento clínico de los pacientes ingresados con enfermedad de Alzhéimer

Introducción: La principal causa de demencia degenerativa es la enfermedad de Alzhéimer. En la población cubana, una de cada cuatro personas de 65 años y más fallece por esta enfermedad u otra forma de demencia. Objetivo : Identificar los factores de riesgo asociados al agravamiento clínico de los pacientes ingresados con enfermedad de Alzhéimer en el Hospital Psiquiátrico Universitario Rene Vallejo Ortiz entre enero de 2013 y diciembre de 2022. Métodos: Se realizó un estudio observacional, descriptivo y transversal. El universo estuvo integrado por todos los pacientes ingresados en la mencionada institución asistencial y docente. La muestra no probabilística y a criterio de los autores la integraron 77 pacientes adultos con el diagnóstico de la enfermedad en el periodo de estudio señalado. Las historias clínicas fueron la fuente secundaria de información. Se utilizó estadística descriptiva e inferencial. La información se resumió en tablas y gráficos. Resultados: El 90,6 % presentaban más de 60 años y más de la mitad eran del sexo masculino (54,5 %). La mayoría de los pacientes presentaron diversos síntomas asociados. Lo trastornos de personalidad y orientación se constataron en el 75,3 % mientras que los de memoria en el 72,7 %. Conclusiones: El agravamiento clínico luego del ingreso hospitalario se acentuó en aquellos pacientes sin escolaridad, solteros, desocupados, con enfermedades cerebro vasculares y presencia de familias disfuncionales presentaron. Los pacientes anémicos o con signos de irritación cortical focal en región frontoparietal con generalización secundaria presentaron mayoritariamente un empeoramiento clínico.

Introduction: The main cause of degenerative dementia is Alzheimer's disease. In the Cuban population, one in four people aged 65 and over dies from this disease or another form of dementia. Objective: To identify the risk factors associated with the clinical worsening of patients admitted with Alzheimer's disease at the Rene Vallejo Ortiz University Psychiatric Hospital. Methods: An observational, descriptive and cross-sectional study was carried out. The universe was made up of all patients admitted to the aforementioned healthcare and teaching institution. The non-probabilistic sample and at the discretion of the authors was made up of 77 adult patients with the diagnosis of the disease in the indicated study period between January 2013 and December 2022. Medical records were the secondary source of information. Descriptive and inferential statistics were used. The information was summarized in tables and graphics. Results: 90.6% were over 60 years old and more than half were male (54.5%). Most patients presented various associated symptoms. Personality and orientation disorders were found in 75.3%, while memory disorders were found in 72.7%. Conclusions: The clinical worsening after hospital admission was accentuated in those patients without schooling, single, unemployed, with cerebrovascular diseases and presence of dysfunctional families. Anemic patients or patients with signs of focal cortical irritation in the frontoparietal region with secondary generalization mostly presented clinical worsening.
