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.

Características de la población femenina carcelaria: un caso de la región Caribe de Colombia / Characteristics of the female prison population: a case from the Caribbean region of Colombia / Características da população carcerária feminina: um caso da região caribenha da Colômbia

El objetivo del presente trabajo fue describir las características de las mujeres privadas de libertad (MPL) de un centro de detención carcelario de la región Caribe de Colombia, a partir de un método cuantitativo, descriptivo, transversal, mediante el uso de unidades de análisis documental de una muestra de 202 archivos psicojurídicos de mujeres privadas de libertad, durante los años 2021 y 2022. En estos archivos se encuentran 25 variables divididas en tres grupos. Primer grupo: características sociodemográficas de la población; segundo grupo: datos históricos, relativos a antecedentes familiares y de salud mental; tercer grupo: aspectos relacionados con la conducta delictiva. De acuerdo con los resultados encontrados, la mayor parte de la población son madres, con escaso acceso a oportunidades laborales, bajo nivel de escolaridad, con precarios ingresos económicos, antecedentes de victimización psicológica, sexual o física, exposición a violencia indirecta, antecedentes de abandono y, en algunos casos, se identificó la presencia de diagnósticos en salud mental, consumo de sustancias, comorbilidad y experiencias traumáticas durante su infancia y adolescencia y la prisionalización de padres o familiares. Estos resultados permiten reconocer la importancia de los aspectos históricos y los antecedentes de la conducta delictiva femenina, lo cual resulta fundamental en la prevención de la criminalidad, haciendo frente a los factores de riesgo previos a la conducta delictiva femenina; igualmente, la relevancia del fortalecimiento de un modelo carcelario de cara a las características y necesidades de la población femenina, una política criminal y un sistema penitenciario de género sensitivo, así como la incorporación de los resultados encontrados en el tratamiento carcelario, en la resocialización y en la prevención del fenómeno criminal.

The aim of this study was to describe the characteristics of women deprived of liberty (MPL) in a prison detention centre in the Caribbean region of Colombia, based on a quantitative, descriptive, cross-sectional method, using units of documentary analysis of a sample of 202 psycho-legal files of women deprived of liberty, during the years 2021 and 2022. These files contain 25 variables divided into three groups. First group: socio-demographic characteristics of the population; second group: historical data, relating to family history and mental health; third group: aspects related to criminal behaviour. According to the results found, most of the population are mothers, with little access to job opportunities, low level of schooling, precarious economic income, history of psychological, sexual or physical victimisation, exposure to indirect violence, history of abandonment and, in some cases, the presence of mental health diagnoses, substance use, comorbidity and traumatic experiences during childhood and adolescence and the imprisonment of parents or relatives were identified. These results allow us to recognise the importance of the historical aspects and background of female criminal behaviour, which is fundamental in the prevention of criminality, addressing the risk factors prior to female criminal behaviour; also, the relevance of strengthening a prison model that takes into account the characteristics and needs of the female population, a criminal policy and a gender-sensitive penitentiary system, as well as the incorporation of the results found in prison treatment, in re-socialisation and in the prevention of the criminal phenomenon

Esses arquivos contêm 25 variáveis divididas em três grupos. Primeiro grupo: características sociodemográficas da população; segundo grupo: dados históricos, relativos à história familiar e à saúde mental; terceiro grupo: aspectos relacionados ao comportamento criminal. De acordo com os resultadosencontrados, a maior parte da população é composta por mães, com pouco acesso a oportunidades de trabalho, baixo nível de escolaridade, renda econômica precária, histórico de vitimização psicológica, sexual ou física, exposição à violência indireta, histórico de abandono e, em alguns casos, foi identificada a presença de diagnósticos de saúde mental, uso de substâncias, comorbidade e experiências traumáticas durante a infância e a adolescência e o encarceramento dos pais ou parentes. Esses resultados permitem reconhecer a importância dos aspectos históricos e dos antecedentes do comportamento criminoso feminino, o que é fundamental na prevenção da criminalidade, abordando os fatores de risco anteriores ao comportamento criminoso feminino; também, a relevância do fortalecimento de um modelo prisional diante das características e necessidades da população feminina, de uma política criminal e de um sistema prisional sensível ao gênero, bem como a incorporação dos resultados encontrados no tratamento prisional, na ressocialização e na prevenção do fenômeno criminal.

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.

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.

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.

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.

Non-linear association between long-term air pollution exposure and risk of metabolic dysfunction-associated steatotic liver disease

BACKGROUND@#Metabolic Dysfunction-associated Steatotic Liver Disease (MASLD) has become a global epidemic, and air pollution has been identified as a potential risk factor. This study aims to investigate the non-linear relationship between ambient air pollution and MASLD prevalence.@*METHOD@#In this cross-sectional study, participants undergoing health checkups were assessed for three-year average air pollution exposure. MASLD diagnosis required hepatic steatosis with at least 1 out of 5 cardiometabolic criteria. A stepwise approach combining data visualization and regression modeling was used to determine the most appropriate link function between each of the six air pollutants and MASLD. A covariate-adjusted six-pollutant model was constructed accordingly.@*RESULTS@#A total of 131,592 participants were included, with 40.6% met the criteria of MASLD. "Threshold link function," "interaction link function," and "restricted cubic spline (RCS) link functions" best-fitted associations between MASLD and PM2.5, PM10/CO, and O3 /SO2/NO2, respectively. In the six-pollutant model, significant positive associations were observed when pollutant concentrations were over: 34.64 µg/m3 for PM2.5, 57.93 µg/m3 for PM10, 56 µg/m3 for O3, below 643.6 µg/m3 for CO, and within 33 and 48 µg/m3 for NO2. The six-pollutant model using these best-fitted link functions demonstrated superior model fitting compared to exposure-categorized model or linear link function model assuming proportionality of odds.@*CONCLUSION@#Non-linear associations were found between air pollutants and MASLD prevalence. PM2.5, PM10, O3, CO, and NO2 exhibited positive associations with MASLD in specific concentration ranges, highlighting the need to consider non-linear relationships in assessing the impact of air pollution on MASLD.

Epidemiological characteristics and influencing factors of adenovirus-associated acute conjunctivitis in Shenzhen，2014‒2022 / 上海预防医学

ObjectiveTo investigate the epidemic characteristics and influencing factors of acute conjunctivitis caused by human adenovirus（HAdv）in Yantian District of Shenzhen City， Guangdong Province from 2014 to 2022， and to provide evidence for formulating effective prevention and control measures. MethodsDescriptive epidemiology was used to analyze the epidemiological characteristics of acute hemorrhagic conjunctivitis （AHC） cases reported from the Chinese disease prevention and control information system. Etiological characteristics of laboratory-confirmed cases were analyzed， and a case-control study method of test-negative design （TND） was conducted as well. According to the result of HAdv detection， analysis was used to identify the influencing factors of morbidity. ResultsA total of 1 005 AHC cases were reported in Yantian District， Shenzhen City from 2014 to 2022， with an average annual incidence rate of 49.49/105. The incidence rate ranged from 4.67/105 to 117.28/105. The peak incidence occurred from July to October each year， with a male-to-female ratio of 1.42∶1. The median （P25，P75） age of onset was 29（12，40） years. A total of 716 eye swabs were collected for etiological detection from 2014 to 2022. HAdv positive detection rate was 36.45% （263/716）， Cox 24v positive detection rate was 0.28% （2/716）， while EV70 was not detected. The longest viral shedding time in eye swabs was 10 days， with a median of 2 days. The highest HAdv positive detection rate （47.47%） was observed when the sampling-to-onset interval was 4‒5 days， and the difference was statistically significant （P<0.05）， with a trend of first increasing and then decreasing. Multivariate logistic regressing analysis showed that aged 18‒ years， and average temperature higher than 24.90 ℃ 3 days before onset （P<0.05） were the risk factors for acute HAdv conjunctivitis. ConclusionAHC in Yantian District， Shenzhen City showed a low level of prevalence from 2014 to 2022， with HAdv being the predominant pathogen. The peak period of viral shedding occurred on the 4th to 5th day after symptom onset， suggesting the importance of adherence to strict home isolation for infected persons. Aged18‒ years and average temperature increased 3 days before onset are associated with an increased risk of adenoviral conjunctivitis. It is recommended to strengthen personal protection and keep doing a good job of AHC surveillance and early warning， so as to timely prevent the outbreaks of AHC.

Clinical features and early warning indicators of patients with acute-on-chronic liver failure and bacterial infection / 临床肝胆病杂志

ObjectiveTo investigate the clinical features of patients with acute-on-chronic liver failure （ACLF） and bacterial infection and early warning indicators associated with multidrug-resistant infections. MethodsA retrospective analysis was performed for 130 patients with ACLF and bacterial infection who attended The Second Affiliated Hospital of Air Force Medical University from January 1， 2010 to December 31， 2021， and according to the drug susceptibility results， the patients were divided into multidrug-resistant （MDR） bacterial infection group with 80 patients and non-MDR bacterial infection group with 50 patients. General information and laboratory examination results were compared between the two groups to screen for the early warning indicators associated with MDR bacterial infection. The Student’s t-test was used for comparison of normally distributed continuous data with homogeneity of variance between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data or continuous data with heterogeneity of variance between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The binary logistic regression analysis and the receiver operating characteristic （ROC） curve were used to assess the predictive value of early warning indicators. ResultsAmong the 130 patients with ACLF and bacterial infection， sputum （27.7%） was the most common specimen for detection， followed by blood （24.6%）， urine （18.5%）， and ascites （17.7%）. Bacterial infections were dominated by Gram-negative bacteria （58.5%）. Of all bacteria， Escherichia coli （18.5%）， Klebsiella pneumoniae （14.6%）， and Enterococcus faecium （13.8%） were the most common pathogens. Gram-positive bacteria had a high resistance rate to the antibacterial drugs such as erythromycin （72.2%）， penicillin （57.4%）， ampicillin （55.6%）， and ciprofloxacin （53.7%）， while Gram-negative bacteria had a high resistance rate to the antibacterial drugs such as ampicillin （73.3%）， cefazolin （50.0%）， and cefepime （47.4%）. The patients with ACLF and bacterial infection had a relatively high rate of MDR bacterial infection （61.5%）. Comparison of clinical data between the two groups showed that compared with the patients with non-MDR bacterial infection， the patients with MDR bacterial infection had significantly higher levels of alanine aminotransferase （Z=2.089， P=0.037）， aspartate aminotransferase （Z=2.063， P=0.039）， white blood cell count （Z=2.207， P=0.027）， and monocyte count （Z=4.413， P<0.001）. The binary logistic regression analysis showed that monocyte count was an independent risk factor for MDR bacterial infection （odds ratio=7.120， 95% confidence interval ［CI］： 2.478‍ ‍—‍ ‍20.456，P<0.001） and had an area under the ROC curve of 0.686 （95%CI： 0.597‍ ‍—‍ ‍0.776） in predicting ACLF with MDR bacterial infection（P<0.001）， with the optimal cut-off value of 0.50×109/L， a sensitivity of 0.725， and a specificity of 0.400. ConclusionACLF combined with bacterial infections is mainly caused by Gram-negative bacteria， with the common pathogens of Escherichia coli and Klebsiella pneumoniae and a relatively high MDR rate in clinical practice. An increase in monocyte count can be used as an early warning indicator to distinguish MDR bacterial infection from non-MDR bacterial infection.

Predictive Value of Serum Albumin Levels for Coronary Artery Calcification in Patients with Early Chronic Kidney Disease / 中山大学学报(医学科学版)

ObjectiveTo explore the correlation between serum albumin levels and coronary artery calcification （CAC） in patients with early-stage chronic kidney disease （CKD）， as well as the value of serum albumin levels in predicting the incidence and severity of CAC. MethodsThe study included 391 early-stage CKD patients who underwent coronary computed tomography angiography （CTA） at Sun Yat-sen Memorial Hospital of Sun Yat-sen University between January 2019 and December 2022. Demographic and biochemistry data， as well as the coronary CTA results， were collected. Based on the coronary artery calcification score （CACS）， all patients were divided into non-CAC group （CACS=0， n=184） and CAC group （CACS>0， n=207）. All patients were further divided into 3 groups based on the serum albumin levels： group A （serum albumin levels<35 g/L， n=30）， group B （35 g/L≤ serum albumin levels< 40 g/L， n=198） and group C （serum albumin levels≥ 40 g/L， n=163）. Univariate and multivariate binary logistic regression analyses were conducted to investigate the association between serum albumin levels and CAC in early-stage CKD patients. Differences in CAC among groups were analyzed by using post-hoc multiple comparisons and ordinal logistic regression model analysis. ResultsPatients with CAC had significantly lower serum albumin levels than those without CAC （P<0.05）. There was a negative correlation between serum albumin levels and CACS in early-stage CKD patients （P<0.01）， as serum albumin decreased in levels， CAC increased in severity. ConclusionsOur study shows that early-stage CKD patients with lower serum albumin levels have a higher incidence of CAC. Low serum albumin level is an independent risk factor for CAC progression.

Clinical features, risk factors and treatment of type 2 diabetes mellitus in patients with acute exacerbation of chronic obstructive pulmonary disease / 中国临床药理学与治疗学

AIM: To investigate the clinical features of acute exacerbation chronic obstructive pulmonary disease (AECOPD) of complicated with type 2 diabetes mellitus (T2DM), and analyze the related clinical features and risk factors. METHODS: This was a single-center cross-sectional study. From March 2020 to January 2023, 479 hospitalized patients with AECOPD in the department of respiratory and critical care medicine, Suining Central Hospital were included. There were 215 patients in AECOPD group and 60 patients in AECOPD with T2DM group. The collected variables included demographic data, complications, blood routine, infection index, random blood glucose, blood gas analysis and lung function. The adoption rate and constituent ratio of the basic description classification data were expressed as mean standard deviation for the normal distribution measurement data and median interquartile range for the skew distribution measurement data. T-test was used for normal distribution and non - parameter test was used for non-normal distribution. The categorical variables were tested by chi-square test. Rank sum test was used for rank variable data. Binary logistic regression model was used to investigate the independent factors associated with T2DM in patients with AECOPD. Finally, the results of logistic regression were verified and visualized by nomogram, validation curve, ROC curve and DCA curve. P0.05). The results of logistic regression were verified and visualized by Nomogram and its-associated ccurves. The MAE and AUC curves were 0.021 and 0.847 respectively, indicating that the model had good prediction consistency and accuracy. The DCA curve showed that Nomogram's risk threshold ranged from 0.01 to 0.99, suggesting that nomogram's model had better clinical predictive value. CONCLUSION: Our results showed that increased BMI, PaCO2 and random glucose, decreased blood lymphocyte, and atrial fibrillation is an independent clinical feature of AECOPD with T2DM. These results suggest that the immune function of patients with AECOPD and T2DM are more severely impaired and more likely to be accompanied by atrial fibrillation, which is a potential cause of poor prognosis in these patients. Meanwhile, this conclusion needs to be further verified in multicenter study with large sample size.

Physical fitness and characteristics of cognitive function among people aged 55 to 75 years with high and low risk of dementia in communities in Beijing / 中国康复理论与实践

ObjectiveTo analyze the risk factors of dementia among healthy elderly individuals in the middle of their lives. MethodsA total of 175 participants aged 55 to 75 from two communities in Beijing were included from July, 2021 to April, 2023. Cardiovascular Risk Factors, Aging, and Incidence of Dementia (CAIDE) related risk factors and other demographic data were collected. According to the CAIDE assessment, participants with scores ≥ 9 were as high-risk group, and those with scores < 9 were as low-risk group. They were evaluated with Stroop Color Word Test (SCWT), two elements 1-back task paradigm and the revised Trail Making Test (TMT); measured the grip strength, 30 s forearm flexion tests and five sit-to-stand tests; the average step speed and step length of a 10-meter walk were recorded. ResultsThe average total score of CAIDE was 9.86 in the high-risk group, and was 4.95 in the low-risk group. There was no difference in age between two groups (P = 0.188). There were differences in the proportion of participants of male, less than seven years' education, systolic blood pressure > 140 mmHg, cholesterol > 6.5 mmol/L, body mass index > 30 kg/m2, and lack of physical activity between two groups (χ2 > 3.116, P < 0.05). The grip strength (t = -4.174), walking speed (t = -2.414), SCWT accuracy (Z = -2.684) were all worse in the high-risk group than in the low-risk group (P < 0.05). Logistic regression analysis showed that walking speed (OR = 25.483), grip strength (OR = 1.133) and SCWT accuracy (OR = 37.430) were independent influencing factors of dementia (P < 0.05). ConclusionWeaker grip strength, slower gait speed and worse inhibitory control might be independent influencing factors of dementia.

ObjectiveTo investigate the value of baseline red cell distribution width （RDW） and alkaline phosphatase （ALP） level after ursodeoxycholic acid （UDCA） treatment for one month in predicting the response to UDCA treatment in patients with primary biliary cholangitis （PBC）. MethodsA retrospective analysis was performed for the data of 127 patients with PBC who were diagnosed in Department of Hepatology， The Third People’s Hospital of Jiangsu University， from January 2015 to July 2022， with data collected at baseline， after one month of treatment， and after one year of follow-up. Based on the Paris-I criteria， the patients were divided into good response group and poor response group， and the two groups were analyzed in terms of clinical and laboratory features and their association with response to UDCA. The Logistic regression method was used to investigate the independent risk factors for response to UDCA treatment. The area under the ROC curve （AUC） was used to determine the optimal cut-off values of related indicators； the patients were divided into two groups based on such values， and the two groups were compared in terms of baseline indicators and response. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between two groups. ResultsCompared with the good response group， the poor response group had significantly higher levels of total bilirubin， aspartate aminotransferase/alanine aminotransferase， ALP， RDW， and RDW-CV at baseline and a significantly higher level of ALP after one month of UDCA treatment （Z=-4.792， -3.697， -2.399， -4.102， -3.220， and -4.236， all P<0.05）. Compared with the good response group， the poor response group had significantly lower levels of albumin， hemoglobin， lymphocytes， hematocrit， and body mass index at baseline （Z=-3.592， -3.603， -2.602， -3.829， -2.432， all P<0.05）， as well as significantly lower levels of prealbumin， albumin/globulin ratio， apolipoprotein A， and free triiodothyronine at baseline （t=4.530， 3.402， 3.485， and 3.639， all P<0.001）. Compared with the poor response group， the good response group had a significantly lower proportion of patients with liver cirrhosis， gallstones/cholecystitis， or anemia （χ2=20.815， 3.892， and 12.283， all P<0.05）. Baseline RDW （odds ratio ［OR］=1.157， 95% confidence interval ［CI］： 1.028‍ — ‍1.301， P=0.015） and ALP level after one month of treatment （OR=1.012， 95%CI： 1.005‍ — ‍1.020， P=0.002） were independent risk factors for response to UDCA， with an AUC of 0.713 and 0.720， respectively. The patients with baseline RDW≥upper limit of normal （ULN） and ALP≥2.2×ULN after one month of UDCA treatment had a lower UDCA response rate （42.6% vs 8.2%， χ2=20.813， P<0.001）. ConclusionPatients with baseline RDW≥ULN and ALP≥2.2×ULN after one month of UDCA treatment tend to have a low biochemical response rate to UDCA.

Research progress of related factors affecting poor response to wet age-related macular degeneration / 国际眼科杂志(Guoji Yanke Zazhi)

Wet age-related macular degeneration(wARMD)emerges as a primary contributor to irreversible vision impairment in the aging demographic. In clinical practice, anti-vascular endothelial growth factor(VEGF)therapies exhibit pronounced success in managing wARMD. However, in the actual clinical application, there are significant individual differences in the prognosis of anti-VEGF drug therapy, and some patients show poor response to the treatment, which may be related to the morphological differences of retinal layers in macular area, genetics, systemic conditions and other factors. It will help develop a more rational and individualized treatment plan to judge the prognosis of patients according to their different clinical manifestations in advance, so as to reduce overtreatment and the risk of retinal damage. In recent years, most studies on treatment response mainly focus on fundus morphology, genetics and so on. In this study, the relevant factors affecting adverse response to wARMD were reviewed, aiming to provide with more accurate treatment and prognostic monitoring programs for clinicians.

@#Introduction: Chronic non-communicable respiratory diseases (CNCRDs) encompass a group of conditions affecting the airways and lung structures, including Chronic Obstructive Pulmonary Disease (COPD), emphysema, allergic rhinitis, asthma, pulmonary arterial hypertension, and cystic fibrosis. CNCRDs pose a significant global health challenge, resulting in approximately four million deaths annually. This study aimed to identify the prevalence and risk factors associated with CNCRDs and measure trends in the prevalence of these risk factors over time. Methods: A cross-sectional epidemiological study was conducted using data collected from primary health centers on both sides of Mosul City. The study period extended from January 1 to July 31, 2022, with information obtained from (40) primary health centers, consisting of (20) centers on the right side and (20) centers on the left side of Mosul. Results: In 2021, the City of Mosul recorded a total of 13,005 registered cases, with 5,598 cases being attributed to asthma (43%), and 7,347 cases being associated with COPD (57%). Bronchial asthma constituted 43% of cases, with 5598 patients, and the highest incidence occurred in the age group between 20-44 years. Conclusion: The prevalence of bronchial asthma and COPD among patients with CNCRDs in Mosul is alarmingly high. It emphasizes the importance of implementing preventive policies and strategies targeting modifiable risk factors for these respiratory conditions.

Trend of Colorectal Cancer Burden in China from 1990 to 2019 / 肿瘤防治研究

Objective To quantitatively analyze the effects of population aging and other risk factors on the burden of colorectal cancer in China from 1990 to 2019. Methods The Global Burden of Disease Study 2019 was used to describe the temporal trend of the burden of colorectal cancer. A decomposition method established by Gupta was applied to quantify the burden related to population growth, aging, age-specific prevalence, and disease severity. Results The age-standardized disability adjusted life years (DALY) rates of colorectal cancer in China showed an overall upward trend from 1990 to 2019. The DALY in 2019 increased by 191.12% compared with that in 1990, with 34.54% of the increase attributed to population growth, 111.36% to population aging, and 77.56% to the rise of age-specific prevalence. Meanwhile, -32.54% benefited from the changes in disease severity. Diet low in milk was the primary risk factor for the disease burden of colorectal cancer in China in 2019, followed by diet low in whole grains and calcium. In the last 30 years, the corresponding risk factor of the most rapid increase in China was high BMI with an average annual percentage of change of 4.14%, and the corresponding risk factor of the most rapid decrease in China was diet low in fiber with an average annual percentage of change of -2.00%. Conclusion Aging population is mainly responsible for the considerable increase in the burden of colorectal cancer in China from 1990 to 2019. The health administrative authorities should take corresponding measures to address the adverse impacts associated with aging.
