Perfil de pacientes adultos hospitalizados por COVID-19 antes y después de la introducción de las vacunas contra SARS-CoV-2

Introducción: La introducción progresiva de vacunas contra SARS-CoV-2 a partir de 2021, priorizando grupos de mayor edad, podría implicar un cambio en el perfil de pacientes hospitalizados por COVID-19 en el tiempo. Objetivo: Comparar las características y evolución de pacientes adultos hospitalizados por COVID-19 en un período anterior en 2020 (PER1) y otro posterior al inicio de la vacunación masiva contra SARS-CoV-2 (PER2). Pacientes y Métodos: Se registró edad, género, comorbilidades, complicaciones y evolución de los pacientes hospitalizados por COVID-19 en una clínica privada, en Santiago, Chile. Se calculó el puntaje de gravedad y riesgo nutricional. Resultados: En PER2, los pacientes fueron de menor edad, pero con comorbilidades similares al PER1, excepto por mayor malnutrición por exceso. Los pacientes del PER2 no vacunados requirieron más ventilación mecánica (38,9 vs. 14,3%, p = 0,03) y evolucionaron más gravemente (puntaje 6) que aquellos adecuadamente inmunizados (puntaje 5, p = 0,048). Las variables que más predijeron mortalidad fueron edad > 60 años (OR 28.995) y presencia de riesgo nutricional (OR 5.246). Discusión: El cambio en el perfil y evolución de los pacientes hospitalizados con COVID-19 está asociado con la secuencia de priorización de vacunas contra SARS-CoV-2, cuyo efecto redujo las hospitalizaciones y gravedad de COVID-19 en adultos mayores.

Background: During the COVID-19 pandemic, the early prioritization of SARS-CoV-2 vaccines for older adults may have affected the characteristics of hospitalized COVID-19 patients over time. Aim: To compare the clinical characteristics and outcomes of adult patients admitted for COVID-19 before (PER1) and after (PER2) the initiation of mass vaccination for SARS-CoV-2. Methods: Data on age, gender, comorbidities, complications, and outcomes of adult patients hospitalized for COVID-19 in a private clinic of Santiago, Chile, were collected. Scores for COVID-19 severity and nutritional risk were calculated. Results: In PER2, patients were younger but had similar comorbidities, except for a higher prevalence of overweight and obesity compared to PER1. Unvaccinated COVID-19 patients in PER2 required more invasive ventilatory support (38.9% vs. 14.3%, p = 0.03) and had a higher severity score (six) than vaccinated patients (five, p = 0.048). The variables that best predicted mortality were age > 60 years (OR 28,995) and the presence of nutritional risk (OR 5,246). Discussion: Changes in the profile and outcomes of hospitalized patients during the COVID-19 pandemic are associated with the prioritization of SARS-CoV-2 vaccines and their protective effect in reducing hospitalizations and disease severity in older adults.

Histological risk score and its role in predicting recurrence in early-stage oral squamous cell carcinomas

Context: Oral squamous cell carcinoma (OSCC) comprises more than 90% of oral cancers and is the most common carcinoma affecting the oral cavity. Early stage T1/T2 OSCC have a heterogeneous prognosis and a significant number of patients develop loco regional recurrence (LRR) and have reduced disease free survival (DFS) with increased disease related mortality. Aims and Objectives: To assess the impact of the three parameters used in Brandwein-Gensler risk model along with lympho-vascular invasion (LVI), depth of invasion (DOI) and lymph node metastases in predicting LRR in early stage OSCC. Materials and Methods: This was a retrospective study on early stage T1/2 OSCC patients over a period of 2 years who received treatment by surgical resection and had follow-up data. LRR was assessed based on recurrence of OSCC at the initial site or in regional lymph nodes. Results: Out of 1135 OSCC cases during our study period a total of 207 cases befitted our inclusion criteria. Recurrence was noted in 113 (54.6%) cases. Univariate analysis identified LVI (P < 0.00001), DOI (P < 0.00001), nodal involvement (P < 0.00001), worst pattern of invasion (WPOI) (P < 0.00001), lymphocytic host response (LHR) (P = 0.004), perineural invasion (PNI) (P = 0.012) as strong statistically significant risk factors for LRR. Conclusion: Adequate assessment of simple parameters on routine H and E by incorporating Brandwein-Gensler histological risk scoring model at the initial presentation can help prognosticate and predict LRR and select patients for post-surgical adjuvant therapy.

Relación entre el Finnish Diabetes Risk Score, glucemia en ayunas y hemoglobina A1c / Relationship between the Finnish Diabetes Risk Score, fasting blood glucose and glycohemoglobin A1c

Introducción: el Finnish Diabetes Risk Score (FINDRISC) mostró alta sensibilidad y especificidad para la detección de personas que evolucionarían a diabetes mellitus (DM) en las poblaciones estudiadas, por lo cual se decidió utilizarlo entre quienes concurrieron por diferentes motivos a realizarse análisis de laboratorio en centros de la Asociación de Laboratorios de Alta Complejidad (ALAC), con el objeto de identificar personas con diferentes niveles de riesgo de presentar alteraciones de la glucemia en ayunas (GA) y de la HbA1c. Objetivos: explorar la asociación entre la puntuación del FINDRISC con GA y HbA1c, estableciendo el punto de corte de mayor sensibilidad y especificidad para encontrar una GA ≥100 mg/dL y una HbA1c ≥5,7% (38,8 mmol/mol), en una población que concurrió a centros de la ALAC. Materiales y métodos: se incluyeron 1.175 individuos de 45 laboratorios de la ALAC, procesamiento local de glucemia y centralizado de HbA1c (high performance liquid chromatography, HPLC). Análisis estadístico: chi-cuadrado, Odds Ratio, ANOVA, test de Tukey, regresión logística binomial y curvas ROC. Resultados: los puntajes totales del FINDRISC se asociaron de manera positiva y estadísticamente significativa, tanto con los valores de GA como con los niveles de HbA1c. Entre sus variables, una edad mayor o igual a 45 años, un perímetro abdominal de alto riesgo, un índice de masa corporal mayor o igual a 25 Kg/m., la presencia de antecedentes familiares de DM (padres, hermanos o hijos) y la existencia de antecedentes de medicación antihipertensiva se asociaron de manera significativa con valores de GA iguales o superiores a 100 mg/dL y/o niveles de HbA1c iguales o mayores a 5,7% (38,8 mmol/mol). No se halló asociación significativa con la realización de actividad física (al menos 30 minutos diarios) ni con el registro de ingesta diario de frutas y verduras. Los valores medios de GA y HbA1c en individuos con puntajes totales del FINDRISC menores o iguales a 11 fueron de 89,9 mg/dL y 5,2% (33,0 mmol/mol), respectivamente, elevándose hasta valores medios de 116,1 mg/dL y 6,1% (43,0 mmol/mol) en los individuos con puntajes iguales o superiores a 21, siguiendo una asociación del tipo "dosis/respuesta". Por curvas ROC, un FINDRISC de 13 presenta una sensibilidad del 81,89%, especificidad del 67,60% y 70,55% de diagnósticos correctos de HbA1c ≥5,7% (38,8 mmol/mol), y una sensibilidad del 72,50%, especificidad del 70,62% y 71,20% de diagnósticos correctos para encontrar personas con una GA ≥100 mg/dL. Conclusiones: el puntaje del FINDRISC se relacionó con niveles crecientes de GA y HbA1c, resultando útil para encontrar personas con GA ≥100 mg/dL y HbA1c ≥5,7% (38,8 mmol/mol) en la población estudiada.

Introduction: the Finnish Diabetes Risk Score (FINDRISC) has high sensitivity and specificity for the identification of people at risk of diabetes mellitus (DM) in various populations. Therefore, we aimed to use this index to identify individuals at risk of having alterations in fasting glycemia (FG) and HbA1c among those who underwent laboratory analysis at ALAC, Argentina. Objectives: to explore the relationships of the FINDRISC score with the fasting blood glucose (FG) concentration and glycated hemoglobin (HbA1c) level, and to establish appropriate cut-off scores to predict FG ≥100 mg/dL and HbA1c ≥5.7% (38.8 mmol/mol) in this population. Materials and methods: we recruited 1,175 individuals from 45 ALAC laboratories for whom FG and HbA1c had been measured. We analyzed the data using the chi square test, odds ratios, ANOVA plus Tukey's post-hoc test, binomial logistic regression, and receiver operating characteristic (ROC) curves. Results: total FINDRISC score significantly positively correlated with both FG and HbA1c. Of the constituent variables, age ≥45 years, a large waist circumference, a body mass index ≥25 kg/m., a close family history of DM, and the use of antihypertensive medication were significantly associated with FG ≥100 mg/dL and/or HbA1c ≥5.7% (38.8 mmol/mol). However, no significant association was found with physical activity or the daily consumption of fruit and vegetables. The mean FG and HbA1c for individuals with total FINDRISC scores ≤11 were 89.9 mg/dL and 5.2% (33.0 mmol/mol), respectively, which increased to 116.1 mg/dL and 6.1% (43.0 mmol/mol) for individuals with scores ≥21, with a dose/response-type relationship. ROC analysis showed that a FINDRISC of 13 was associated with a sensitivity of 81.89%, a specificity of 67.60%, and a correct diagnosis rate of 70.55% for HbA1c ≥5.7% (38.8 mmol/mol); and a sensitivity of 72.50%, a specificity of 70.62%, and a correct diagnosis rate of 71.20% for FG ≥100 mg/dL. Conclusions: FINDRISC score increases with increasing FG and HbA1c, and is a useful means of identifying people with FG ≥100 mg/dL and HbA1c ≥5.7% (38.8 mmol/mol).

Assessment of risk of diabetes in medical students using the Indian diabetes risk score

Background: Diabetes is one of the most common causes for morbidity and mortality. Among which type 2 diabetes is the most rampant in which body does not make synthesize or utilize insulin effectively insulin is a hormone that helps the body cells to utilize glucose for energy production. Deficiency of insulin leads to high level of glucose in the plasma. Sustained high blood glucose level for a longer duration can lead to serious problems in heart, eyes, kidneys, and nerves. This may lead to complications such as neuropathy, retinopathy, nephropathy, and atherosclerosis. Aim and Objectives: The aim of this study was to identify the risk of diabetes in medical students. Materials and Methods: One hundred medical students in the age group of 18–21 years were screened for prediabetic state using the diabetic risk score and were statically analyzed. Results: Out of 100 students, 57 were found to have low risk, 41 moderate risk, and only two had high risk of diabetes. The results of the present study showed that 49% of students were indulged in mild activity and 25% of the students were not involved in any kind of physical activity. Conclusion: Lack of physical exercise was found to be the major risk factor for diabetes among medical students, and hence, it is suggested that medical students should also stress on physical exercise along with studies.

Diabetes Risk Score in Indian Population: Experience from Central India

Introduction: Diabetes is a major health problem in the world causing significant morbidity and mortality. Currently, 77 million people in India and 463 million people are living with diabetes across the world, and this number is expected to rise to 101 million in India and 578 million globally by 2030. The key to reduce the morbidity and mortality is early diagnosis and management. The Madras Diabetes Research Foundation (MDRF) has developed an Indian Diabetes Risk Score (IDRS) to identify people who are at risk of developing diabetes or are undiagnosed. Thus, we conducted a study to calculate the IDRS of people from Central India and identify those who are at risk of getting diabetes. Methods: A total of 1,500 patients or attendants, aged 18 to 60 years (mean age 41.2 years), visiting the Endocrinology clinic, and not diagnosed with diabetes earlier were included in the study after taking proper consent and IDRS was calculated. Results: The male-to-female ratio was 914:586. The mean IDRS was 51.29 in our population with 35.93%, 18.2% and 45.87% of screened subjects having a score of <30, 30-60 and ?60, respectively. Conclusion: Forty-five percent people of the population was at high risk of diabetes as estimated by IDRS, which proved to be an effective and economical tool to identify persons at increased risk of diabetes and diagnose the undiagnosed cases and start early management to reduce the morbidity and mortality.

Evaluation of Madras Diabetes Research Foundation-Indian Diabetes Risk Score in detecting undiagnosed diabetes in the Indian population: Results from the Indian Council of Medical Research-INdia DIABetes population-based study (INDIAB-15)

Background & objectives: Screening of individuals for early detection and identification of undiagnosed diabetes can help in reducing the burden of diabetic complications. This study aimed to evaluate the performance of Madras Diabetes Research Foundation (MDRF)-Indian Diabetes Risk Score (IDRS) to screen for undiagnosed type 2 diabetes in a large representative population in India. Methods: Data were acquired from the Indian Council of Medical Research–INdia DIABetes (ICMR–INDIAB) study, a large national survey that included both urban and rural populations from 30 states/union territories in India. Stratified multistage design was followed to obtain a sample of 113,043 individuals (94.2% response rate). MDRF-IDRS used four simple parameters, viz. age, waist circumference, family history of diabetes and physical activity to detect undiagnosed diabetes. Receiver operating characteristic (ROC) with area under the curve (AUC) was used to assess the performance of MDRF-IDRS. Results: We identified that 32.4, 52.7 and 14.9 per cent of the general population were under high-, moderate- and low-risk category of diabetes. Among the newly diagnosed individuals with diabetes [diagnosed by oral glucose tolerance test (OGTT)], 60.2, 35.9 and 3.9 per cent were identified under

Risk factors associated with surgical site infection in patients with musculoskeletal cancer / Fatores de risco associados à infecção de sítio cirúrgico em portadores de câncer musculoesquelético / Factores de riesgo asociados a la infección del sitio quirúrgico en pacientes con cáncer musculoesquelético

Background and objectives: surgical site infections (SSI) continue to be a major concern in orthopedic oncology and pose as great a challenge as cancer recurrence, despite the preventive potential of surgery. SSI can be avoided if evidence-based measures are taken. The objective was to assess the frequency of infections in oncological orthopedic surgeries and associated risk factors and inflammatory markers in a reference hospital in the state of Pernambuco. Methods: the frequency of SSI, the identification of isolated microorganisms, the risk factors and the profile of Th1 and Th2 inflammatory markers (IL-2, IL-4, IL-6, IL-10, TNF and IFN-Ƴ) in patients with musculoskeletal cancer were analyzed. Results: SSI were found in 9.1% of patients undergoing orthopedic surgery. Bivariate analysis revealed that a surgical team comprising more than five members (p=0.041) and the need for intraoperative transfusion (p=0.012) were correlated with a higher risk of SSI. The measurement of ultrasensitive C-reactive protein levels to assess the inflammatory response after SSI showed results that were superior to the reference values for each sample, ranging from >5 to >200mg/dl by the immunoturbidimetric method. Of the IL-2, INFγ and TNF (Th1) and IL-4, IL-6, IL-10 (Th2) levels, only interleukin 6 showed high levels, between 6.68 and 58.76 pg/mL. Conclusion: the study found that surgical team with five or more members and blood transfusion were factors associated with the development of SSI in orthopedic surgery in patients with musculoskeletal cancer. Among the inflammatory markers, interleukin 6 (IL-6) showed the highest correlation with the outcome.(AU)

The application of antineutrophil cytoplasmic antibody renal risk score in children with antineutrophil cytoplasmic antibody-associated glomerulonephritis / 中华实用儿科临床杂志

Objective:To investigate the potential of the antineutrophil cytoplasmic antibody (ANCA) renal risk score (ARRS) in predicting the prognosis of children with ANCA-associated glomerulonephritis (AAGN).Methods:Laboratory testing, renal pathology results, treatment and prognosis of 61 children with AAGN diagnosed by renal biopsy from June 2007 to May 2022 in General Hospital of Eastern Theater Command were retrospectively analyzed.The Kaplan-Meier method was used to evaluate the overall and renal survival of children with AAGN, and risk factors of progression to end stage renal disease (ESRD) were analyzed by Cox regression analysis. Results:Among the 61 children with AAGN, there were 14 males and 47 females with the age of (15.65±3.74) years.According to ARRS, AAGN children were assigned into low-risk group (27 cases), medium-risk group (21 cases) and high-risk group (13 cases). During a median follow-up duration of 46.36 (14.58, 95.62) months, the number of ESRD cases in the high-risk group (9 cases) was significantly higher than that of low-risk group (2 cases) and medium-risk group (3 cases) ( χ2=13.079, P<0.001). Kaplan-Meier survival analysis showed that AAGN children in the high-risk group had the worst renal prognosis ( χ2=5.796, P=0.016), while no significant difference was detected in the overall survival among the 3 groups ( χ2=2.883, P=0.237). Multivariate Cox regression showed that estimate glomerular filtration rate(eGFR)≤15 mL/(min·1.73 m 2) ( HR=9.574, 95% CI: 4.205-25.187, P=0.015) and ARRS ( HR=2.115, 95% CI: 1.206-4.174, P=0.012) were independent risk factors for children with AAGN progress to ESRD.Receiver operating characteristic (ROC) curve analysis results showed that the area under the curve of ARRS for predicting the risk of progressing to ESRD in AAGN children was 0.880 (95% CI: 0.759-1.000), and the optimal cutoff value of ARRS was 5.50, with the sensitivity and specificity of 85.71% and 82.98%, respectively. Conclusions:ARRS was an independent risk factor for children with AAGN progress to ESRD, which had a predictive value for the progression of AAGN to ESRD.

Validation of the simple clinical risk score for the early detection of severe dengue in adult patients

Background@#In 2009, the World Health Organization revised the Dengue Fever guidelines to more accurately identify patients at risk of developing severe dengue. Despite these guidelines, early diagnosis of severe dengue remains challenging for clinicians. Several scoring systems have been developed to identify patients at highest risk for severe dengue however; these studies have a study population limited to children and did not include adult patients.@*Objective@#The purpose of this study is to validate the Simple Clinical Risk Score in predicting who will develop severe Dengue among adult patients with Dengue fever.@*Methods@#This is a prospective cohort, single-center, observational study conducted at Silliman University Medical Center from August 2019 to August 2020. A total of 481 laboratory confirmed dengue patients were included and categorized into two models based on the day of illness. Each model used a clinical risk score of 1 point as a cut-off for predicting severe Dengue. Validation was done using the risk-odds ratio and substantiated by the odds ratio, signifying that there is more likely greater association between dengue patients to develop severe dengue.@*Results@#In model 1, a total of 339 patients were analyzed with 6 patients who achieved a score of 1 developed severe Dengue. In model 2, a total of 142 patients were analyzed and 3 patients who achieved a score of 1 developed severe dengue.@*Conclusion@#The simple clinical risk score can assist clinicians in deciding and stratifying dengue patients who need hospitalization not only in resource-limited areas but also during this height of the pandemic. While the findings had a lesser number of participants, it still remained context-specific and is able to demonstrate a predictive ability for severe disease, thereby optimizing informed decisions for hospital admissions in settings with limited laboratory resources.

Prediction of intensive care admission and hospital mortality in COVID-19 patients using demographics and baseline laboratory data

Abstract Introduction: Optimized allocation of medical resources to patients with COVID-19 has been a critical concern since the onset of the pandemic. Methods: In this retrospective cohort study, the authors used data from a Brazilian tertiary university hospital to explore predictors of Intensive Care Unit (ICU) admission and hospital mortality in patients admitted for COVID-19. Our primary aim was to create and validate prediction scores for use in hospitals and emergency departments to aid clinical decisions and resource allocation. Results: The study cohort included 3,022 participants, of whom 2,485 were admitted to the ICU; 1968 survived, and 1054 died in the hospital. From the complete cohort, 1,496 patients were randomly assigned to the derivation sample and 1,526 to the validation sample. The final scores included age, comorbidities, and baseline laboratory data. The areas under the receiver operating characteristic curves were very similar for the derivation and validation samples. Scores for ICU admission had a 75% accuracy in the validation sample, whereas scores for death had a 77% accuracy in the validation sample. The authors found that including baseline flu-like symptoms in the scores added no significant benefit to their accuracy. Furthermore, our scores were more accurate than the previously published NEWS-2 and 4C Mortality Scores. Discussion and conclusions: The authors developed and validated prognostic scores that use readily available clinical and laboratory information to predict ICU admission and mortality in COVID-19. These scores can become valuable tools to support clinical decisions and improve the allocation of limited health resources.

Status de vitamina D e risco cardiovascular em indivíduos com síndrome metabólica / Vitamin D status and cardiovascular risk in individuals with metabolic syndrome

Introdução: A síndrome metabólica é um conjunto de desordens metabólicas, consideradas fatores de risco cardiovascular. Estima-se que indivíduos com síndrome metabólica apresentam probabilidade três vezes maior de desenvolver doenças cardiovasculares. O status inadequado de vitamina D tem apresentado múltiplos mecanismos fisiopatológicos que sugerem um envolvimento no desenvolvimento de doenças cardiovasculares. Objetivo: avaliar a associação entre o status de vitamina D e o risco de doenças cardiovasculares em indivíduos com síndrome metabólica. Métodos: Estudo do tipo transversal realizado com 161 indivíduos adultos, diagnosticados com síndrome metabólica. Foram realizadas as medidas antropométricas, pressão arterial, e as análises bioquímicas, incluindo a dosagem de 25(OH)D no soro. O critério estabelecido para classificação do status de 25(OH)D foi deficiente < 20 ng/mL; insuficiente≤ 29 ng/mL e suficiente ≥ 30 ng/mL. Ademais, avaliou-se o risco absoluto de desenvolver doenças cardiovasculares usando o Escore de Risco de Framingham. Resultados: A mediana da concentração de 25(OH)D foi 29,7 (21-34) ng/mL, indicando status de 25(OH)D insuficiente na população. Não houve associação entre status de vitamina D e o risco cardiovascular em indivíduos com síndrome metabólica (p > 0,05). Conclusão: Não se observou associação entre status 25(OH)D inadequado e maior risco cardiovascular nos indivíduos com síndrome metabólica. Entretanto,esses resultados reforçam a importância do monitoramento clínico para prevenir os impactos da hipovitaminose D nos indivíduos com síndrome metabólica e o desenvolvimento de novos estudos para avaliar a relação entre status de 25(OH)D e risco cardiovascular.

Introduction: Metabolic syndrome is a set of metabolic disorders that are considered cardiovascular risk factors. It is estimated that individuals with metabolic syndrome are three times more likely to develop cardiovascular disease. Inadequate vitamin D status has shown multiple pathophysiological mechanisms that suggest an involvement in the development of cardiovascular disease. Objective: To evaluate the association between vitamin D status and the risk of cardiovascular disease in individuals with metabolic syndrome. Methods: This is a cross-sectional study carried out with 161 adult individuals diagnosed with metabolic syndrome. Anthropometric measurements, blood pressure, and biochemical analyzes were performed, including serum 25(OH)D status. The established criterion for classifying 25(OH)D status was deficient < 20 ng/mL; insufficient ≤ 29 ng/mL and sufficient ≥ 30 ng/mL. Furthermore, the absolute risk of developing cardiovascular disease was assessed using the Framingham Risk Score. Results: The mean 25(OH)D concentration was 29.7 (21-34) ng/mL, indicating insufficient 25(OH)D status in the population. There was no association between vitamin D status and cardiovascular risk in subjects with metabolic syndrome (p > 0.05). Conclusion: There was no association between inadequate 25(OH)D status and increased cardiovascular risk in individuals with metabolic syndrome. However, these results reinforce the importance of clinical monitoring to prevent the impacts of hypovitaminosis D in individuals with metabolic syndrome and the development of new studies to assess the relationship between 25(OH)D status and cardiovascular risk.

Association of PI3K/AKT/mTOR pathway autophagy-related gene polymorphisms with pulmonary tuberculosis susceptibility in a Chinese population

ABSTRACT Background: Autophagy can inhibit the survival of intracellular microorganisms including Mycobacterium tuberculosis (Mtb), and the PI3K/AKT/mTOR pathway plays a crucial role. This study investigated the association between PI3K/AKT/mTOR pathway autophagy-related gene polymorphisms and pulmonary tuberculosis (PTB) susceptibility. Methods: KEGG pathway and gene ontology (GO) databases were searched for genes belonging to the PI3K/AKT/mTOR and autophagy pathways. Thirty SNPs in nine genes were identified and tested for their associations with tuberculosis in 130 patients with PTB and 271 controls. We constructed genetic risk scores (GRSs) and divided the participants into 3 subgroups based on their GRSs:0-5, 6-10, and 11-16. Results: This analysis revealed that the AKT1 (rs12432802), RPTOR (rs11654508, rs12602885, rs2090204, rs2589144, and rs2672897), and TSC2 (rs2074969) polymorphisms were significantly associated with PTB risk. A decreasing trend was observed (P trend 0.020), in which a lower GRS was associated with a higher risk of PTB ([6-10] vs. [0-5]: OR (95%CI) 0.590 (0.374-0.931); [11-16] vs. [0-5]: OR (95%CI) 0.381 (0.160-0.906)). Conclusions: Polymorphisms in AKT1, RPTOR, and TSC2 may influence susceptibility to PTB.

Computed tomography features and prediction model of stage-IA solitary nodular invasive mucinous lung adenocarcinoma / 中国辐射卫生

@#<b>Objective</b> To investigate the computed tomography (CT) features of solitary nodular invasive mucinous lung adenocarcinoma (IMA) in stage IA and establish its prediction model. <b>Methods</b> We included 53 lesions of 53 patients with stage-IA IMA and 141 control lesions of 141 patients with invasive non-mucinous lung adenocarcinoma (NIMA) that were confirmed by surgical pathology in our hospital from January 2017 to December 2019. Univariable analysis was used to compare the demographics and CT signs of the two groups. Multivariable logistic regression analysis was performed to determine the main factors influencing solitary nodular IMA. A risk score prediction model was constructed based on the regression coefficients of the main influencing factors. A receiver operating characteristic (ROC) curve was used to assess the performance of the model. <b>Results</b> The univariable analysis showed significant differences between the two groups in age, largest nodule diameter, tumor-lung interface, lobulation, spiculation, air-bronchogram or vacuole sign, vessel abnormalities (<i>P</i> < 0.05). The spiculation sign was different between the two groups, which was longer and softer in the IMA group while shorter and harder in the NIMA group. There was no significant difference in sex, nodule shape, or pleural retraction (<i>P</i> > 0.05), but irregular shapes were slightly more frequent in the IMA group. The multivariable logistic regression analysis showed that obscure tumor-lung interface (odds ratio (<i>OR</i> = 20.930, <i>P</i> < 0.05), air-bronchogram or vacuole sign (<i>OR</i> = 7.126, <i>P</i> < 0.05), spiculation sign (<i>OR</i> = 4.207, <i>P</i> < 0.05), and vessel abnormalities (<i>OR</i> = 0.147, <i>P</i> < 0.05) were the main influencing factors. The prediction model based on those factors’ regression coefficients had an area under the ROC curve of 0.829 (<i>P</i> < 0.05). <b>Conclusion</b> Compared with those with NIMA, patients with solitary nodular IMA in stage IA were older and more likely to have the CT features of obscure tumor-lung interface, air-bronchogram or vacuole sign, and longer and softer spiculation. Based on the regression coefficients of tumor-lung interface, air-bronchogram or vacuole sign, spiculation, and vessel abnormalities, the risk score prediction model showed good predictive performance for solitary nodular IMA.

The GRACE risk score predicts no-reflow and MACE in patients with STEMI undergoing PCI / 西安交通大学学报(医学版)

【Objective】 Coronary no-reflow during percutaneous conranary intervention (PCI) often results in the failure of ischemic myocardial reperfusion and major adverse cardiovascular events (MACE). The present study sought to evaluate whether the GRACE risk score can predict coronary no-reflow in STEMI patients undergoing PCI. 【Methods】 We consecutively recruited 1 118 patients with STEMI who were admitted to Gansu Provincial People’s Hospital and The First Affiliated Hospital of Xi’an Jiaotong University from January 2009 to December 2011. Main demographic data, cardiovascular risk factors, blood lipid and other biochemical indicators were recorded. Coronary angiography was performed by a radial artery approach using the standard Judkins technique. Coronary no-reflow was evaluated by at least two independent experienced cardiologists. The GRACE risk score was calculated with a computer program. All the cases were followed up by medical records, face-to-face interviews or telephone calls. Finally, we analyzed the predictive value of the GRACE risk score for coronary non-reflow and MACE in STEMI patients undergoing PCI. 【Results】 During a median period of 36 months, 58 of the 1 118 patients (5.2%) were lost to follow-up. Of the remaining 1 060 patients, 118 (11.1%) had no-reflow and 147 (13.9%) had MACE. The GRACE score was higher in patients with no-reflow than those without no-reflow. Multivariate logistic regression established that the GRACE score was an independent predictor for coronary no-reflow (OR=1.034; P=0.002). And multivariate Cox analysis showed the GRACE score was an independent predictor of MACE. The area under the ROC curve for coronary no-reflow and MACE was 0.719 and 0.697, respectively. Kaplan-Meier analysis showed that the probability of rehospitalization for heart failure, reinfarction, all-cause death and cumulative cardiovascular events increased with the increase of the GRACE risk score. 【Conclusion】 The GRACE risk score is a readily available predictive scoring system for coronary no-reflow and MACE in STEMI patients.

Establishment and evaluation of risk prediction model for the esophageal cancer via whole transcriptome analysis / 中国胸心血管外科临床杂志

@#Objective    To establish the gene-based esophageal cancer (ESCA) risk score prediction models via whole transcriptome analysis to provide ideas and basis for improving ESCA treatment strategies and patient prognosis. Methods    RNA sequencing data of esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC) and adjacent tissues were obtained from The Cancer Genome Atlas database. The edgeR method was used to screen out the differential genes between ESCA tissue and normal tissue, and the key genes affecting the survival status of ESCC and EAC patients were initially identified through univariate Cox regression analysis. The least absolute shrinkage and selection operator regression analysis and multivariate Cox regression analysis were used to further screen genes and establish ESCC and EAC risk score prediction models. Results    The risk score prediction models were the independent prognostic factors for ESCA, and the risk score was significantly related to the survival status of patients. In ESCC, the risk score was related to T stage. In EAC, the risk score was related to lymph node metastasis, distant metastasis and clinical stage. The constructed nomogram based on risk score showed good predictive ability. In ESCC, the risk score was related to tumor immune cell infiltration and the expression of immune checkpoint genes. However, this feature was not obvious in EAC. Conclusion 聽 聽The ESCC and EAC risk score prediction models have shown good predictive capabilities, which provide certain inspiration and basis for optimizing the management of ESCA and improving the prognosis of patients.

Application value of the aortic dissection detection risk score plus D-dimer for the early diagnosis of acute aortic dissection / 中国基层医药

Objective:To investigate the application value of aortic dissection detection risk score (ADD-RS) combined with D-dimer (DD) in the early diagnosis of acute aortic dissection (AAD).Methods:The clinical data of 70 patients with suspected aortic dissection detection admitted to The Second Hospital of Jiaxing from August 2019 to April 2020 were collected. All patients were scored using the ADD-RS, and grouped according to the scoring results. The sensitivity and specificity of ADD-RS plus DD in the early diagnosis of AAD were calculated. The areas under the receiver operating characteristic (ROC) curves that were plotted for drADD-RS plus DD versus DD alone to screen AAD were compared to evaluate efficacy. Results:CT angiography results showed that among 70 patients with suspected AAD, 29 patients had AAD and 41 patients had no AAD. A total of 21 patients were scored 0, 41 patients were scored > 1, and 8 patients were scored > 0. ADD-RS > 0 had an overall sensitivity of 79.31% and a specificity of 36.59% for AAD diagnosis. DD test results had an overall sensitivity of 86.20% and a specificity of 36.50% for AAD diagnosis. The area under the ROC curve of ADD-RS = 0 plus DD-negative result and the area under the ROC curve of DD-negative result alone in ruling out AAD were 0.885 with 95% CI (0.786-0.949) and 0.787 with 95% CI (0.673-0.876), respectively. The difference between the two groups was statistically significant ( P = 0.024). Conclusion:Compared with DD-negative result alone, the ADD-RS = 0 plus DD-negative result strategy offers greater specificity to rule out AAD. The combined strategy has a greater efficacy in ruling out AAD. However, a multi-center study involving a large sample is required for in-depth evaluation.

Diabetes Risk Score in Indian Population: Experience from Central India

Introduction: Diabetes is a major health problem in the world causing significant morbidity and mortality. Currently, 77 million people in India and 463 million people are living with diabetes across the world, and this number is expected to rise to 101 million in India and 578 million globally by 2030. The key to reduce the morbidity and mortality is early diagnosis and management. The Madras Diabetes Research Foundation (MDRF) has developed an Indian Diabetes Risk Score (IDRS) to identify people who are at risk of developing diabetes or are undiagnosed. Thus, we conducted a study to calculate the IDRS of people from Central India and identify those who are at risk of getting diabetes. Methods: A total of 1,500 patients or attendants, aged 18 to 60 years (mean age 41.2 years), visiting the Endocrinology clinic, and not diagnosed with diabetes earlier were included in the study after taking proper consent and IDRS was calculated. Results: The male-to-female ratio was 914:586. The mean IDRS was 51.29 in our population with 35.93%, 18.2% and 45.87% of screened subjects having a score of <30, 30-60 and ?60, respectively. Conclusion: Forty-five percent people of the population was at high risk of diabetes as estimated by IDRS, which proved to be an effective and economical tool to identify persons at increased risk of diabetes and diagnose the undiagnosed cases and start early management to reduce the morbidity and mortality.

Assessment of Cardiovascular Disease Risk among Perimenopausal Women :A Cross-sectional Study in a Rural Area of West Bengal

Introduction :Cardiovascular disease (CVD) has become the leading cause of mortality in the world, more so in the perimenopausal age group due to decreased levels of estrogen and diminished ovarian function because of ageing. To find out the magnitude of CVD risk among perimenopausalObjective: women residing in rural Bengal and its associated determinants. A cross-sectional study wasMethod: conducted in a rural area of Barasat block I during April-July 2021 on 150 peri-menopausal women selected by cluster sampling. A pre-designed pretested questionnaire was used for data collection and a 10-year probability of CVD risk was assessed using Framingham Risk Score. Logistic regression analysis was done to find out the associated factors. Intermediate & high CVD risk was present in 28 (18.7%) and 63Results: (42%) participants respectively. Among 150 participants, 62% were hypertensive, 44.7% were diabetic,, 51.3% with borderline high total cholesterol and 76% had low HDL cholesterol. Factors significantly associated with intermediate to high CVD risk were high mental stress [AOR=6.96, 95%CI=2.17-22.31], family history of chronic illness [AOR=14.46, 95% CI=4.26-49.06] and presence of chronic morbidities [AOR=6.84, 95%CI=1.93-24.22]. A significant proportion of perimenopausal women were atConclusion: risk of developing CVD. Thus, awareness campaigns in the community would help in empowering women in maintaining their health through regular screening and timely intervention when deemed necessary

Predictive Value of TIMI Risk Index for Angiographic No-reflow after Primary Percutaneous Coronary Intervention

Objective: In patients with acute coronary artery disease, the TIMI risk index (TRI), the thrombolysis in myocardial infarction (TIMI) risk score, and the global registry of acute coronary events (GRACE) risk score (GRS) have all been documented. The aim of this study was to determine the relationship between no-reflow (NRF) and admission TRI, major cardiac events (MACE), and in-hospital mortality in patients undergoing primary percutaneous coronary intervention (P-PCI). Methods: Between March and December 2019, 100 consecutive patients diagnosed with STEMI and treated with PPCI at Tanta Main University Hospital in Tanta, Egypt, were included in the research population. Each patient consented following a thorough history taking, evaluation of coronary risk factors, clinical examination, and electrocardiogram analysis. Additionally, all instances were classified using the Killip method. The GRS, TRS, and TRI values were examined. Results: The GRS, TRS, and TRI scores were significantly associated with increased NRF, MACE, and hospital mortality in STEMI patients treated with P-PCI, suggesting that TRI is a straightforward indicator with fewer parameters that accurately reflects P-PCI success. Conclusion: TRI has been demonstrated to enhance the risk of in-hospital mortality and MACE. TRI uses straightforward and cost-effective ways to test patients who have experienced a STEMI. Additionally, a high TRI may assist in identifying high-risk individuals and developing suitable treatment solutions.
