INTRODUCTION: The anthropometric indicators of obesity may be important in predicting metabolic syndrome (MS). OBJECTIVE: To evaluate the anthropometric indicators as predictors of MS and verify the association of these indicators with MS in older adult individuals of both sexes. METHODS: Cross-sectional epidemiological study was carried out with 222 individuals aged 60 years or older residents in the urban area of Aiquara, Bahia state, Brazil. Older adults were measured for anthropometric indicators: body mass index (BMI), waist-to-height ratio (WHtR), waist circumference, conicity index, the sum of skinfolds; blood pressure; biochemical variables: fasting glucose, triglycerides, total cholesterol, and fractions. For the diagnosis of MS, the definition of the International Diabetes Federation was used. Descriptive and inferential data analysis was tested using correlation, the Poisson regression technique, and the Receiver Operating Characteristic (ROC) curve. RESULTS: The prevalence of MS was 62.3%. There was a correlation of all anthropometric indicators with MS in both sexes. The indicators of visceral fat had a strong association in that these indicators had an area under the ROC curve higher than 0.76 (CI95% 0.66­0.85). Thus, most results showed a weak correlation. CONCLUSION: All anthropometric indicators can be used to predict MS in older adults for both sexes, however, BMI and WHtR showed the best predictions.

INTRODUÇÃO: Os indicadores antropométricos de obesidade podem ser importantes na predição da síndrome metabólica (SM). OBJETIVO: Avaliar os indicadores antropométricos como preditores da SM, bem como verificar a associação desses indicadores com a SM em idosos de ambos os sexos. MÉTODOS: Estudo epidemiológico transversal realizado com 222 indivíduos com 60 anos ou mais residentes na zona urbana de Aiquara-BA, Brasil. Os idosos foram avaliados quanto aos indicadores antropométricos: índice de massa corporal (IMC), razão cintura-estatura (RCEst), circunferência da cintura, índice de conicidade, soma de dobras cutâneas; pressão sanguínea; bioquímicos: glicemia em jejum, triglicérides, colesterol total e frações. Foram classificados quanto à presença de SM de acordo com a Federação Internacional de Diabetes. A análise descritiva e inferencial dos dados foi testada utilizando correlação, a técnica de regressão de Poisson e a curva Receiver Operating Characteristic (ROC). RESULTADOS: A prevalência de SM foi de 62,3%. Houve correlação de todos os indicadores antropométricos com a SM em ambos os sexos. Os indicadores de gordura visceral apresentaram forte associação, pois possuem área abaixo da curva ROC superior a 0,76 (IC95% 0,66-0,85). Assim, a maioria dos resultados apresentou correlação fraca. CONCLUSÃO: Todos os indicadores antropométricos podem ser usados para rastrear a SM em idosos de ambos os sexos, no entanto, o IMC e a RCEst apresentaram as melhores previsões.

ABSTRACT BACKGROUND: Quick and accurate identification of critically ill patients ensures appropriate and correct use of medical resources. In situations that threaten public health, like pandemics, rapid and effective methods are needed for early disease detection among critically ill patients. OBJECTIVE: To determine the relationship between the neutrophil-to-lymphocyte ratio (NLR) of coronavirus disease-19 (COVID-19) patients upon admission to the emergency department (ED) and these patients' prognosis. DESIGN AND SETTING: Retrospective cohort study among COVID-19 patients in the ED of a tertiary-level hospital. METHODS: Data on patients' age, gender, vital signs, chronic diseases, laboratory tests and clinical outcomes were collected from electronic medical records. Receiver operating characteristic (ROC) curve analysis was performed. The area under the curve (AUC) was used to assess the accuracy of NLR for predicting in-hospital mortality risk and intensive care unit (ICU) requirement. The Youden J index (YJI) was used to determine optimal threshold values. RESULTS: 1,175 patients were included. Their median age was 63 years (IQR, 48-75). With an NLR cutoff value of 5.14, the sensitivity, specificity, PPV, AUC and YJI for ICU requirement were calculated as 77.87%, 74.08%, 92.4%, 0.811 and 0.5194, respectively. With the same cutoff value, the sensitivity, specificity, AUC and YJI for in-hospital mortality were 77.27%, 75.82%, 0.815 and 0.5309, respectively. In addition, advanced age, leukocytosis, anemia and lymphopenia were found to be associated with poor prognosis. CONCLUSION: The NLR, which is a widely available simple parameter, can provide rapid insights regarding early recognition of critical illness and prognosis among COVID-19 patients.

Resumo Fundamento Os níveis de Proteína 3 relacionada ao fator de necrose tumoral/complemento sérico C1q (CTRP3) e a relação com a fibrilação atrial (FA) na doença arterial coronária estável (DAC) não estão claros atualmente. Objetivos O objetivo deste estudo foi investigar a mudança nos níveis séricos de CTRP3 e sua relação com a FA paroxística em DAC estável. Método O estudo incluiu 252 pacientes com DAC e 50 controles saudáveis com idade/sexo compatíveis. Os níveis séricos de CTRP3 foram medidos, além da anamnese de rotina, exame físico, exames laboratoriais e ecocardiograma. Os pacientes foram divididos em grupos com e sem DAC e indivíduos com DAC com e sem FA paroxística. Os valores eram estatisticamente significativos quando p<0,05. Resultados Os níveis séricos de CTRP3 foram significativamente menores em pacientes com DAC do que no grupo controle (p<0,001). A FA foi detectada em 28 pacientes (15,08%) no grupo DAC. A frequência de hipertensão e do sexo feminino, a proteína C reativa de alta sensibilidade (PCR-as), o nitrogênio ureico no sangue, os níveis de creatinina e o diâmetro diastólico do átrio esquerdo foram maiores (p<0,05 para cada um), e os níveis de CTRP3 foram mais baixos em pacientes com FA (p<0,001). Na análise de regressão logística, os níveis séricos de CTRP3 e os diâmetros diastólicos do átrio esquerdo foram independentemente determinados pelos pacientes com FA (p<0,01 para cada um). Nesta análise, observamos que cada 1 ng/mL de redução nos níveis de CTRP3 aumentou o risco de FA em 10,7%. Na análise ROC dos valores de CTRP3 para detectar pacientes com FA, a área da curva ROC para CTRP3 foi 0,971 (0,951-991) e considerada estatisticamente significativa (p<0,001). Quando o ponto de corte de CTRP3 foi considerado em 300 ng/mL, demonstrava a presença de FA com 87,9% de sensibilidade e 86,8% de especificidade. Conclusão Os níveis séricos de CTRP3 caíram significativamente em pacientes com DAC estável, e níveis reduzidos de CTRP3 estiveram relacionados à presença de FA paroxística nesses pacientes.

Abstract Background Serum Complement C1q/tumor necrosis factor-related protein-3 (CTRP3) levels and the relationship with atrial fibrillation (AF) in stable coronary artery disease (CAD) are not clearly known. Objective The aim of this study was to investigate the change in serum CTRP3 levels and its relationship with paroxysmal AF in stable CAD. Method The study included 252 patients with CAD and 50 age-sex matched healthy control subjects. Serum CTRP3 levels were measured in addition to routine anamnesis, physical examination, laboratory and echocardiography examinations. The patients were divided into groups with and without CAD and CAD patients with and without paroxysmal AF. Statistical significance was accepted as p<0.05. Results Serum CTRP3 levels were found to be significantly lower in patients with CAD than in the control group (p<0.001). AF was detected in 38 patients (15.08%) in the CAD group. The frequency of hypertension and female gender, hs-CRP, blood urea nitrogen, creatinine levels and left atrial end-diastolic (LAd) diameter were higher (p<0.05 for each one), and CTRP3 levels were lower in patients with AF (p <0.001). In the logistic regression analysis, serum CTRP3 levels and LAd diameters were independently determined the patients with AF (p<0.01 for each one). In this analysis, we found that every 1 ng/mL reduction in CTRP3 levels increased the risk of AF by 10.7%. In the ROC analysis of CTRP3 values for detecting patients with AF, the area under the ROC curve for CTRP3 was 0.971 (0.951-991) and was statistically significant (p<0.001). When the CTRP3 cut-off value was taken as 300 ng/mL, it was found to predict the presence of AF with 87.9% sensitivity and 86.8% specificity. Conclusion Serum CTRP3 levels were significantly reduced in patients with stable CAD and decreased CTRP3 levels were closely related to the presence of paroxysmal AF in these patients.

SUMMARY OBJECTIVE: The aim of this study was to evaluate and compare C-reactive protein and C-reactive protein-to-albumin ratio performances in predicting mortality of geriatric patients who visited the emergency department. METHODS: The data of patients with COVID-19 and aged 65 years and above, who visited emergency department during the study period, were retrospectively analyzed. The data were obtained from an electronic-based hospital information system. The area under the receiver operating characteristic curve and the area under the curve were used to assess each cutoff value discriminatory for predicting mortality. RESULTS: The mean age of the population included in this study was 76 (71-82) years, while 52.7% were males. The sensitivity, specificity, and area under the curve values for C-reactive protein in terms of mortality were calculated as 71.01, 52.34, and 0.635%, respectively, while the sensitivity, specificity, and area under the curve values for C-reactive protein-to-albumin ratio were calculated as 75.74, 47.66, and 0.645%, respectively (p<0.001). In the pairwise comparison for the receiver operating characteristic curves of C-reactive protein and C-reactive protein-to-albumin ratio, no statistically significant difference was found. CONCLUSIONS: Geriatric patients are the "most vulnerable" patient group against the COVID-19. In this study, both C-reactive protein and C-reactive protein-to-albumin ratio were found to be successful in predicting mortality for geriatric COVID-19 patients.

ABSTRACT Objective: VEGF-D is a potential biomarker for lymphangioleiomyomatosis (LAM); however, its diagnostic performance has yet to be systematically studied. Methods: We searched PubMed, EMBASE, Scopus, Web of Science, and Cochrane Library to identify primary studies on VEGF-D in relation to the diagnosis of LAM. The quality of the studies was evaluated using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). Summary estimates of diagnostic accuracy were pooled using a bivariate random effects model. Subgroup and sensitivity analyses were performed to explore possible heterogeneity. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was applied to rate the quality of evidence and indicate the strength of recommendations. Results: Ten studies involving 945 patients were of high risk in quality, as assessed using the QUADAS-2. The pooled diagnostic parameters were indicated as follows: sensitivity = 0.82 (95% CI, 0.71-0.90); specificity = 0.98 (95% CI, 0.94-0.99); and diagnostic OR = 197 (95% CI, 66-587). The AUC of summary ROC analysis was 0.98. The subgroup and sensitivity analyses revealed that the overall performance was not substantially affected by the composition of the control group, prespecified cutoff value, the country of origin, or different cutoff values (p > 0.05 for all). A strong recommendation for serum VEGF-D determination to aid in the diagnosis of LAM was made according to the GRADE. Conclusions: VEGF-D seems to have great potential implications for the diagnosis of LAM in clinical practice due to its excellent specificity and suboptimal sensitivity.

RESUMO Objetivo: O VEGF-D é um potencial biomarcador para linfangioleiomiomatose (LAM); entretanto, seu desempenho diagnóstico ainda não foi sistematicamente estudado. Métodos: Foram realizadas buscas nos bancos de dados PubMed, EMBASE, Scopus, Web of Science e Cochrane Library para identificar estudos primários sobre o VEGF-D com relação ao diagnóstico de LAM. A qualidade dos estudos foi avaliada por meio da ferramenta Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). As estimativas sumárias de acurácia diagnóstica foram combinadas utilizando um modelo bivariado de efeitos aleatórios. Análises de subgrupo e de sensibilidade foram realizadas para explorar possíveis heterogeneidades. O sistema Grading of Recommendations Assessment, Development, and Evaluation (GRADE) foi aplicado para avaliar a qualidade das evidências e indicar a força das recomendações. Resultados: Dez estudos envolvendo 945 pacientes eram de alto risco em qualidade, segundo a ferramenta QUADAS-2. Os parâmetros diagnósticos combinados foram indicados da seguinte forma: sensibilidade = 0,82 (IC95%: 0,71-0,90); especificidade = 0,98 (IC95%: 0,94-0,99); e OR diagnóstica = 197 (IC95%: 66-587). A ASC da análise summary ROC foi de 0,98. As análises de subgrupo e de sensibilidade revelaram que o desempenho global não foi substancialmente afetado pela composição do grupo controle, valor de corte pré-especificado, país de origem ou diferentes valores de corte (p > 0,05 para todos). Uma forte recomendação para a dosagem de VEGF-D sérico para auxiliar no diagnóstico de LAM foi feita de acordo com o sistema GRADE. Conclusões: O VEGF-D parece ter grandes implicações potenciais para o diagnóstico de LAM na prática clínica em virtude da excelente especificidade e sensibilidade subótima.

Abstract Introduction: Stroke is a complication that causes considerable morbidity and mortality during the heart surgery postoperative period (incidence: 1.3 to 5%; mortality: 13 to 41%). Models for assessing the risk of stroke after heart surgery have been proposed, but most of them do not evaluate postoperative morbidity. The aim of this study was to develop a risk score for postoperative stroke in patients who undergo heart surgery with cardiopulmonary bypass. Methods: A cohort study was conducted with data from 4,862 patients who underwent surgery from 1996 to 2016. Logistic regression was used to assess relationships between risk factors and stroke. Data from 3,258 patients were used to construct the model. The model's performance was then validated using data from the remainder of the patients (n=1,604). The model's accuracy was tested using the area under the receiver operating characteristic (ROC) curve. Results: The prevalence of stroke during the postoperative period was 3% (n=149); 59% of the patients who exhibited this outcome were male, 51% were aged ≥ 66 years, and 31.5% of the patients died. The variables that remained as independent predictors of the outcome after multivariate analysis were advanced age, urgent/emergency surgery, peripheral arterial occlusive disease, history of cerebrovascular disease, and cardiopulmonary bypass time ≥ 110 minutes. The area under the ROC curve was 0.71 (95% confidence interval 0.66 - 0.75). Conclusion: We were able to develop a risk score for stroke after heart surgery. This score classifies patients as low, medium, high, or very high risk of a surgery-related stroke.

Abstract Objective To evaluate the mean uterine artery pulsatility index (UtAPI) in each trimester of pregnancy as a predictor of early or late pre-eclampsia (PE) in Colombian pregnant women. Methods The UtAPI was measured in singleton pregnancies in each trimester. Uterine artery pulsatility index as predictor of PE was evaluated by odds ratio (OR), receiver operating characteristic (ROC) curves, and Kaplan-Meier diagram. Results Analysis in the 1st and 3rd trimester showed that abnormal UtAPI was associated with early PE (OR: 5.99: 95% confidence interval [CI]: 1.64-21.13; and OR: 10.32; 95%CI: 2.75-42.49, respectively). Sensitivity and specificity were 71.4 and 79.6%, respectively, for developing PE (area under the curve [AUC]: 0.922). The Kaplan-Meier curve showed that a UtAPI of 0.76 (95%CI: 0.58-1.0) in the 1st trimester was associated with early PE, and a UtAPI of 0.73 (95%CI: 0.55-0.97) in the 3rd trimester was associated with late PE. Conclusion Uterine arteries proved to be a useful predictor tool in the 1st and 3rd trimesters for early PE and in the 3rd trimester for late PE in a pregnant population with high prevalence of PE.

Resumo Objetivo Avaliar o índice médio de pulsatilidade da artéria uterina (UtAPI) em cada trimestre da gravidez como preditor de pré-eclâmpsia (PE) precoce ou tardia em gestantes colombianas. Métodos O UtAPI foi medido em gestações únicas em cada trimestre. O UtAPI como preditor de PE foi avaliado por odds ratio (OR), curvas receiver operating characteristic (ROC) e diagrama de Kaplan-Meier. Resultados A análise no 1° e 3° trimestres mostrou que um UtAPI anormal foi associado com PE inicial (OR: 5,99; intervalo de confiança [IC] 95%: 1,64-21,13; OR: 10,32; IC95%: 2,75-42,49, respectivamente). A sensibilidade e a especificidade foram de 71,4 e 79,6%, respectivamente, para o desenvolvimento de PE (area under the curve [AUC]: 0,922). A curva de Kaplan-Meier mostrou que um UtAPI de 0,76 (IC95%: 0,58- 1,0) no 1° trimestre foi associado com PE precoce, e que um UtAPI de 0,73 (IC95%: 0,55-0,97) no 3° trimestre foi associado com PE tardia. Conclusão As artérias uterinas mostraram ser uma ferramenta preditora útil no 1° e 3° trimestres para PE inicial e no 3° trimestre para PE tardia em uma população de gestantes com alta prevalência de PE.

ABSTRACT BACKGROUND: Many scoring systems for predicting mortality, rebleeding and transfusion needs among patients with upper gastrointestinal bleeding (UGIB) have been developed. However, no scoring system can predict all these outcomes. OBJECTIVE: To show whether the perfusion index (PI), compared with the Rockall score (RS), helps predict transfusion needs and prognoses among patients presenting with UGIB in emergency departments. In this way, critical patients with transfusion needs can be identified at an early stage. DESIGN AND SETTING: Prospective cohort study in an emergency department in Turkey, conducted between June 2018 and June 2019. METHODS: Patients' demographic parameters, PI, RS, transfusion needs and prognosis were recorded. RESULTS: A total of 219 patients were included. Blood transfusion was performed in 174 patients (79.4%). The PI cutoff value for prediction of the need for blood transfusion was 1.17, and the RS cutoff value was 5. The area under the curve (AUC) value for PI (AUC: 0.772; 95% confidence interval, CI: 0.705-0.838; P < 0.001) was higher than for RS (AUC: 0.648; 95% CI: 0.554-0.741; P = 0.002). 185 patients (84.5%) were discharged, and 34 patients (15.5%) died. The PI cutoff value for predicting mortality was 1.1, and the RS cutoff value was 7. The AUC value for PI (AUC: 0.743; 95% CI: 0.649-0.837; P < 0.001) was higher than for RS (AUC: 0.725; 95% CI: 0.639-0.811; P < 0.001). CONCLUSION: PI values for patients admitted to emergency departments with UGIB on admission can help predict their need for transfusion and mortality risk.

ABSTRACT Objective: Identifying significant fibrosis is crucial to evaluate the prognosis and therapeutic interventions in patients with nonalcoholic fatty liver disease (NAFLD). We assessed the performance of acoustic radiation force impulse (ARFI) elastography, APRI, FIB-4, Forns, NFS and BARD scores in determining liver fibrosis in severe obesity. Subjects and methods: A prospective study included 108 patients undergoing bariatric surgery. Liver biopsy specimens were obtained intraoperatively and classified according to the NAFLD Activity Score. Patients were assessed with serological markers and shear wave velocity of the liver was measured with the Siemens S2000 ultrasound system preoperatively. Optimal cut-off values were determined using the area under the receiver operating characteristic curves (AUROC). Results: In the entire cohort prevalence of NAFLD was 80.6%, steatohepatitis 25.9% and significant fibrosis 19.4%. The best tests for predicting significant fibrosis were FIB-4 and Forns scores (both AUROC 0.78), followed by APRI (AUROC 0.74), NFS (AUROC 0.68), BARD (AUROC 0.64) and ARFI (AUROC 0.62). ARFI elastography was successful in 73% of the patients. Higher body mass index (BMI) correlated with invalid ARFI measurements. In patients with BMI < 42 kg/m2, ARFI showed 92.3% sensitivity and 82,6% specificity for the presence of significant fibrosis, with AUROC 0.86 and cut-off 1.32 m/s. Conclusions: FIB-4 and Forns scores were the most accurate for the prediction of significant fibrosis in bariatric patients. Applicability and accuracy of ARFI was limited in individuals with severe obesity. In patients with BMI < 42 kg/m2, ARFI elastography was capable for predicting significant fibrosis with relevant accuracy.

Abstract Objective: To estimate the accuracy of neck circumference measurement as a method of diagnosing excess weight of six and seven-year-old children. Methods: 1026 six and seven-year-old children were included and anthropometric data were collected using cut-off points for the Body Mass Index (BMI) Z-score, in addition to the measurement of their neck circumference in centimeters. Pearson's correlation coefficient was used to assess the correlation between neck circumference and BMI. Sensitivity, specificity, positive and negative predictive values were calculated. The Receiver Operating Characteristic curve was used to measure the accuracy of neck circumference as a diagnostic method for excess weight. Results: A positive linear correlation value was observed between neck circumference and BMI 0.572 (p < 0.001). The accuracy value of the global ROC curve was 0.772 (p < 0.001). Sensitivity and specificity showed low values, but high positive predictive values were observed, especially between measures of 30 and 31 cm. Conclusion: Neck circumference showed accuracy of 77.2% as a diagnostic method for overweightness in six and seven-year-old children.

SUMMARY OBJECTIVE: Individuals aged ≥65 years are more susceptible to COVID-19 disease and admission to intensive care is most notable. The scoring systems (national early warning score, quick sequential organ failure assessment, shock index) are recommended for rapid assessment of patients in emergency room conditions. The goal of our study is to evaluate scoring systems in conjunction with predictive factors of need for admission to intensive care of patients ≥65 years old with a diagnosis of COVID-19 who applied to the emergency room. METHODS: Patients were divided into two groups according to evolution in the emergency room, being those who needed or not intensive care. National Early Warning Score, quick sequential organ failure assessment, shock index scores and serum biochemistry, blood count and blood gas values were evaluated from hospital information management system records. RESULTS: Of the patients included in the study, 80.8% were admitted to the ward and 14.5% to the unit of intensive care. Lymphocyte count, base deficit and bicarbonate levels were lower, and the levels of C-reactive protein, lactate, D-dimer, urea and lactate dehydrogenase were higher in patients who needed intensive care. Quick sequential organ failure assessment and shock index were considered significant in the group admitted to the intensive care unit. CONCLUSIONS: We recommend that quick sequential organ failure assessment and shock index be used quickly, practically and easily in predicting the need for intensive care unit in patients aged ≥65 years in emergency department diagnosed with COVID-19.

RESUMO Objetivo: Avaliar a utilidade do pico de fluxo da tosse para predizer o desfecho da extubação em pacientes que obtiveram sucesso no teste de respiração espontânea. Métodos: A busca cobriu as bases de dados científicos MEDLINE, Lilacs, Ibecs, Cinahl, SciELO, Cochrane, Scopus, Web of Science e literatura cinzenta. Utilizaram-se os critérios Quality Assessment of Diagnostic Accuracy Studies para avaliar a qualidade da metodologia e o risco de viés dos estudos. A heterogeneidade estatística da razão de verossimilhança (LR) e razão de chance diagnóstica (RCD) do diagnóstico foram avaliadas com utilização de gráficos em floresta, teste Q de Cochran e um gráfico crosshair summary Receiver Operating Characteristic, utilizando um modelo com múltiplos pontos de corte. Resultados: Inicialmente obteve-se, nas bases de dados, um total de 3.522 referências; dentre estas, selecionaram-se para análise qualitativa 12 estudos que incluíram 1.757 participantes. Muitos estudos apresentavam um risco de viés incerto em termos da seleção de pacientes e do fluxo e tempo. Dentre os 12 estudos incluídos, sete tinham alto risco e cinco risco incerto para o item padrão de referência. O desempenho diagnóstico do pico de fluxo da tosse para o resultado da extubação foi baixo a moderado quando se consideram os resultados de todos os estudos incluídos, com +LR de 1,360 (IC95% 1,240 - 1,530), -LR de 0,218 (IC95% 0,159 - 0,293) e razão de chance diagnóstica de 6,450 (IC95% 4,490 - 9,090). Uma análise de subgrupos que incluiu somente estudos com valores de corte entre 55 e 65 L/minuto demonstrou desempenho ligeiramente melhor, porém ainda moderado. Conclusão: A avaliação do pico de fluxo da tosse, considerando valor de corte entre 55 e 65 L/minuto, pode ser útil como medida complementar antes da extubação. São necessários estudos com melhor delineamento para elucidar o melhor método e equipamento para registrar o pico de fluxo da tosse, assim como o melhor ponto de corte.

Abstract Objective: This systematic review was designed to assess the usefulness of cough peak flow to predict the extubation outcome in subjects who passed a spontaneous breathing trial. Methods: The search covered the scientific databases MEDLINE, Lilacs, Ibecs, Cinahl, SciELO, Cochrane, Scopus, Web of Science and gray literature. The Quality Assessment of Diagnostic Accuracy Studies was used to assess the methodological quality and risk of study bias. The statistical heterogeneity of the likelihood (LR) and diagnostic odds ratios were evaluated using forest plots and Cochran's Q statistic, and a crosshair summary Receiver Operating Characteristic plot using the multiple cutoffs model was calculated. Results: We initially retrieved 3,522 references from the databases; among these, 12 studies including 1,757 subjects were selected for the qualitative analysis. Many studies presented an unclear risk of bias in the "patient selection" and "flow and time" criteria. Among the 12 included studies, seven presented "high risk" and five "unclear risk" for the item "reference standard." The diagnostic performance of the cough peak flow for the extubation outcome was low to moderate when we considered the results from all included studies, with a +LR of 1.360 (95%CI 1.240 - 1.530), -LR of 0.218 (95%CI 0.159 - 0.293) and a diagnostic odds ratio of 6.450 (95%CI 4.490 - 9.090). A subgroup analysis including only the studies with a cutoff between 55 and 65 L/minute showed a slightly better, although still moderate, performance. Conclusion: A cough peak flow assessment considering a cutoff between 55 and 65L/minute may be useful as a complementary measurement prior to extubation. Additional well-designed studies are necessary to identify the best method and equipment to record the cough peak flow as well as the best cutoff.

SUMMARY OBJECTIVE: There are limited data about the significance of erythrocyte sedimentation rate as a single prognostic parameter for the prognosis and mortality of COVID-19. This study aimed to investigate the diagnostic utility of erythrocyte sedimentation rate as a prognostic factor for the disease severity and mortality in patients with COVID-19. METHODS: A total of 148 consecutive patients with a confirmed diagnosis of COVID-19 and hospitalized at the intensive care unit or non-the intensive care unit were included in the study. The patients were allocated to groups as severe/critical disease versus nonsevere disease and survivors and nonsurvivors. The prognostic role and predictable values of erythrocyte sedimentation rate were analyzed. RESULTS: Erythrocyte sedimentation rate was found to be higher among patients with severe/critical disease compared to those with nonsevere disease (p<0.001) and among nonsurvivors compared to survivors (p<0.001). The logistic regression analysis showed that erythrocyte sedimentation rate was an independent parameter for predicting disease severity and mortality. The role of erythrocyte sedimentation rate in the assessment of severity and mortality in patients with COVID-19 was analyzed using the receiver operating characteristic curve and was found to be significant in both. The analyses suggested that the optimum erythrocyte sedimentation rate cutoff point for disease severity and mortality were 52.5 mm/h with 65.5% sensitivity and 76.3% specificity and 56.5 mm/h with 66.7% sensitivity and 72.5% specificity. CONCLUSION: Our results suggest that erythrocyte sedimentation rate was an independent prognostic factor for severity and mortality in patients with COVID-19.

ABSTRACT Introduction: The Functional Movement Test (FMS) is an evaluation method for the basic movement patterns of the human body that is designed by Gray Cook. Objective: This paper explores the application value of functional action test (FMS) biological image data in the risk assessment of sports injuries of Chinese rugby players. Methods: Taking the active national football team and provincial football players as the object, the standard FMS test is used to collect the data to determine the best deadline for the total FMS score. Results: The area under the ROC curve (AUC) of the overall athletes, men and women was significantly different from the assumption of AUC=0.5, which were 0.780 (P=0.000), 0.877 (P=0.001), 0.7130 (P=0.013); The best cutoff points corresponding to the total score of FMS are 13.5 points, 15.5 points, and 13.5 points, respectively. The chi-square test showed that the prevalence of the positive group (the total FMS score was less than the corresponding cutoff point) was significantly higher than the negative group (the total FMS score was greater than the corresponding cutoff point) (P<0.01). The OR values of the total athlete, male and female FMS total score positive groups were 25.85 (95%CI: 3.34∼200.23), 25.00 (95%CI: 2.36∼264.80), 14.22 (95%CI: 1.76∼114.92). Conclusions: Among Chinese rugby players, the total score of FMS has a strong correlation with non-contact sports injuries. The score is 13.5 for women and 15.5 for men. Level of evidence II; Therapeutic studies - investigation of treatment results.

SUMMARY OBJECTIVE To explore the values of automated breast volume scanning (ABVS) combined with shear wave elastography (SWE) in the differential diagnosis of triple-negative breast cancer (TNBC) and human epidermal growth factor receptor 2-positive breast cancers (HER2+BC). METHODS In this study, 28 patients with TNBC and 32 patients with HER2+BC were enrolled. The characteristics of ABVS and virtual touch quantification (VTQ) in SWE of all patients were reviewed. The multivariate logistic regression analysis was carried out and the receiver operating characteristic curves of ABVS and ABVS+VTQ were drawn. RESULTS In ABVS imaging, the microcalcification, posterior echo, internal echo, shape, and edge had significant difference between TNBC and HER2+BC groups (p<0.05). The regular shape was the independent factor for TNBC (p=0.04, odds ratio [OR]=4.479), and the microcalcification in mass was the independent factor for HER2+BC (p=0.01, OR=2.997). In VTQ imaging, the shear wave velocity (SWV)max, SWVmin, and SWVmean in TNBC group were significantly lower than those in HER2+BC group (p<0.001). The sensitivity, specificity, and accuracy of ABVS+VTQ in diagnosing TNBC were higher than those of ABVS alone. CONCLUSIONS ABVS combined with SWE has certain advantages in differentiating TNBC from HER2+BC, which is helpful for the treatment planning and prognosis judgment.

SUMMARY OBJECTIVE: Gamma-glutamyl transpeptidase-platelet ratio, system inflammation response index, and systemic immune inflammation index are three systemic immune and inflammation indexes that were investigated for their diagnostic and prognostic proficiencies in cardiovascular diseases and cancers. However, their predictive values for invasive aspergillosis have not yet been studied. The aim of this study was to evaluate Gamma-glutamyl transpeptidase-platelet ratio, system inflammation response index, and systemic immune inflammation index levels and their diagnostic values in invasive aspergillosis. METHODS: A total of 23 patients with invasive aspergillosis and 23 sex- and age-matched healthy participants were included in this study. Complete blood count parameters and liver function tests were studied. Gamma-glutamyl transpeptidase-platelet ratio, system inflammation response index, and systemic immune inflammation index were calculated. RESULTS: Leukocyte, neutrophil, lymphocyte, and monocyte levels were statistically significantly higher in IA group (p=0.031, p=0.027, p=0.033, and p=0.001, respectively). In invasive aspergillosis group, platelets were numerically lower; Aspartate transaminase, alanine aminotransferase, and lactic dehydrogenase levels were numerically higher than those in control group but differences between levels were not statistically significant (p>0.05). The γ-glutamyl transpeptidase levels of patients were statistically significantly higher (p=0.007), and in addition, statistically significant differences were found between groups in terms of gamma-glutamyl transpeptidase-platelet ratio, system inflammation response index, and systemic immune inflammation index (p<0.001, p=0.037, p=0.001, respectively). Receiver operating characteristic analysis was performed, and areas under the curves were evaluated. gamma-glutamyl transpeptidase-platelet ratio had the higher area under the curve than systemic immune inflammation index and system inflammation response index (AUC 0.849, 0.798, 0.693, respectively). The results from receiver operating characteristic analysis of the data suggested that the use of a cutoff value of 0.15 for gamma-glutamyl transpeptidase-platelet ratio would be optimum for clinical use to confirm independent predictors of patients with invasive aspergillosis. CONCLUSIONS: Gamma-glutamyl transpeptidase-platelet ratio is an independent, a useful predictor, and is superior to other evaluated markers in the diagnosis of inflammation in invasive aspergillosis. Gamma-glutamyl transpeptidase-platelet ratio may also be a helpful biomarker for clinicians to follow-up the inflammatory process of these patients.

ABSTRACT Objectives: Develop and validate a new and simplified score for evaluating the lower urinary tract symptoms in men. Materials and methods: We modified the existing visual prostate symptom score, including changes in the images, sequence, and new alternatives, resulting in a new visual score (LUTS visual score-LUTS-V). For the validation of the new tool, we used the International Prostatic Symptom Score as the gold-standard and the new LUTS-V to 306 men. The total IPSS score and the total LUTS-V score of each subject were evaluated to determine the agreement between the two instruments. ROC curve was used to evaluate the diagnostic accuracy and best cut-off of LUTS-V. Sensitivity, specificity, and diagnostic odds ratios were used to describe the diagnostic properties. Results: The mean age of the participants was 59 [52-87] years. There was a significant correlation between LUTS-V and IPSS. (r=0.72 (p <0.0001). The Bland-Altman analyzes demonstrate good agreement between the two questionnaires (bias=5.6%). LUTS-V demonstrated excellent diagnostic accuracy in detecting the most serious cases with an area under the ROC curve of 83% [78-87%] 95% CI. p <0.001). LUTS-V >4 was the best threshold, with a sensitivity of 74% and specificity of 78%. Conclusions: LUTS-V is a simple, self-administered tool with a significant discriminatory power to identify subjects with moderate to severe LUTS and may represent a useful instrument for the diagnosis and follow-up of men with urinary symptoms.

Resumen El índice PROFUND se desarrolló y validó para predecir mortalidad a 12 meses en pacientes pluripatológicos. Sin embargo, su valor potencial para predecir mortalidad intrahospitalaria no ha sido suficientemente estudiado. Se evaluó la capacidad del índice PROFUND en comparación con la proteína C re activa (PCR), la albúmina, y el ancho de distribución eritrocitaria (ADE) para predecir mortalidad intrahospitalaria, mediante el análisis posterior de una cohorte prospectiva de 111 pacientes pluripatológicos internados en clínica médica. La edad promedio fue 75.8 ± 9.3 años. La mortalidad intrahospitalaria fue de 17% (19 pacientes). La mediana (RIQ) del índice PROFUND, albúmina, PCR y ADE en los fallecidos y sobrevivientes fue 12 (4) y 6 (7) p< 0.0001, 2.5 (0.4) y 2.6 (0.8) p 0.295, 58 (64) y 40 (60) p 0.176, 14.5 (2) y 14.6 (3) p 0.523, respectivamente. El análisis logístico multivariado mostró que el índice PROFUND se asocia con mortalidad intrahospitalaria (p 0.0003). El riesgo de fallecer durante la internación es 20% mayor por cada punto que se incrementa el índice PROFUND (OR 1.2, IC95% 1.1-1.4). El área bajo la curva de las características operativas del receptor (AUC-ROC) del índice PROFUND para predecir mortalidad durante la internación (0.760, IC95% 0.628-0.891) fue mayor a la del ADE, PCR y albúmina (0.494 IC95% 0.364-0.624 p 0.012; 0.583 IC95% 0.437-0.728 p 0.028; 0.621 0.494-0.748 p 0.109, respectivamente). El índice PROFUND se asocia a mortalidad intrahospitalaria, con una mayor capacidad predictiva que los biomarcadores estudiados, lo cual se sumaría a su valor pronóstico a largo plazo en pacientes pluripatológicos.

Abstract The PROFUND index was developed and valid to predict mortality at 12 months in polypathological patients (PP). However, its potential value for predicting in-hospital mortality has not been sufficiently studied. The ability of the PROFUND index in comparison with C-reactive protein (CRP), albumin, and red blood cell distribu tion width (RDW) to predict in-hospital mortality was evaluated through the subsequent analysis of a prospective cohort of 111 multiple pathological patients admitted to the clinic medical. The mean age was 75.8 ± 9.3 years. In-hospital mortality was 17% (19 patients). The median (IQR) of the PROFUND index, albumin, CRP and ADE in the deceased and survivors was 12 (4) and 6 (7) p < 0.0001, 2.5 (0.4) and 2.6 (0.8) p 0.295, 58 (64) and 40 (60) p 0.176, 14.5 (2) and 14.6 (3) p 0.523, respectively. The multivariate logistic analysis showed that the PROFUND index is associated with in-hospital mortality (p 0.0003). The risk of dying during hospitalization is 20% higher for each point that the PROFUND index increases (OR 1.2, 95% CI 1.1-1.4). The area under the curve the receiver operating characteristic (AUC-ROC) of the PROFUND index to predict mortality during hospitalization (0.760, 95% CI 0.628-0.891) was higher than that of the RDW, CRP and albumin (0.494 95% CI 0.364-0.624 p 0.012; 0.583 95% CI 0.437-0.728 p 0.028; 0.621 0.494-0.748 p 0.109, respectively). The PROFUND index is associated with in-hospital mortality, with a greater predictive capacity than the biomarkers studied, which would add to its long-term prognostic value in multiple pathological patients.

Abstract Objective: To indicate neck circumference (NC) cutoff points to identify excess weight at different stages of somatic maturation and evaluate the association between NC and body mass index (BMI). Methods: Cross-sectional study with 1715 adolescents. BMI was classified according to the World Health Organization (WHO) criteria. Somatic maturation was obtained through the peak growth velocity (PGV). To define the cutoff points, curves of the receiver operating characteristic (ROC) model were constructed. The agreement between the anthropometric evaluation instruments was analyzed. The association between the variables was verified. Results: Of the girls, 93 were in the pre-PGV stage, 266 in the PGV stage, and 481 in the post-PGV stage. Of the boys, 264 were in the pre-PGV stage, 334 in the PGV stage, and 277 in the post-PGV stage. For the pre-PGV group, the cutoff point was 28 cm for females and 29 cm for males; for the group during PGV, the cutoff points were 30 cm for females and 33 cm for males; in the post-PGV group the cutoff values were 32 cm in females and 35 cm in males. The prevalence of excess weight was higher in the pre-PGV stage in males and in the PGV stage in females. The correlation coefficients were higher in the pre-PGV and PGV stages. Conclusion: The cutoff points for NC found in this study showed good sensitivity and specificity to identify excess weight in Brazilian adolescents and can be used as a reference in epidemiological studies.

ABSTRACT Objective: Male hypogonadism (MH) is common among infertile men. Besides testosterone, limited MH biomarkers are available, while researchers have suggested the use of prostate-specific antigen (PSA) to help diagnose MH. Hence, we sought to evaluate the potential use of PSA to predict MH among relatively young men with infertility in Nigeria. Materials and methods: The study included 707 male partners (35-44 years) in infertile couples seeking infertility evaluation at a third-level care center in Nigeria. MH was diagnosed using standard guidelines. Receiver operating characteristic (ROC) and regression analyses explored the potential of serum free PSA (fPSA) and total PSA (tPSA) in predicting MH and MH-related clinical features. Results: In all, 29.7% of the patients had MH (MH+ve). The MH+ve group had lower mean values of fPSA and tPSA than the group without MH (MH-ve). The best fPSA threshold of < 0.25 μg/L compared with the best tPSA threshold of < 0.74 μg/L had higher accuracy (area under the curve [AUC] 0.908 versus 0.866, respectively), sensitivity (87% versus 83%, respectively), and specificity (42% versus 37%, respectively) for MH diagnosis. After adjustment for confounders, fPSA level ≤ 0.25 μg/L was more likely to predict MH-related decreased libido (odds ratio [OR] 2.728, p<0.001) and erectile dysfunction (OR 3.925, p<0.001) compared with tPSA ≤ 0.74 μg/L in the MH+ve group. Conclusion: For MH diagnosis, fPSA and tPSA had good sensitivity but very poor specificity, although fPSA had better potential for MH diagnosis and association with MH-related clinical features than tPSA. Hence, fPSA could complement other biomarkers for MH diagnosis in men 35-44 years, although we recommend further studies to confirm these findings.
