ABSTRACT

Objective: To analyze the efficacy and safety of paliperidone palmitate 3-monthly (PP3M) in Latin American patients with schizophrenia vs. rest-of-world (ROW). Methods: We analyzed data from two multinational, double-blind (DB), randomized, controlled phase 3 studies including patients with schizophrenia (DSM-IV-TR) previously stabilized on PP1M/PP3M (open-label [OL] phase). Patients were randomized to PP3M or PP1M (noninferiority study A) and PP3M or placebo (study B) in DB phase. The subgroup analysis included Latin American (Argentina, Brazil, Colombia, Mexico) patients. Primary efficacy endpoints were relapse-free rates (study A) and time-to-relapse (study B). Results: In study A, 63/71 (88.7%) and in study B 38/43 (88.4%) Latin American patients completed the DB phase. In study A, relapse-free percentage was similar in Latin America (PP3M: 97%, PP1M: 100%) and ROW (PP3M: 91%, PP1M: 89%). In study B, median time-to-relapse was not estimable in the Latin American subgroup for either placebo or PP3M groups, nor for the ROW PP3M group; the median time-to-relapse in the ROW placebo group was 395 days. Caregiver burden improved in patients switching from oral antipsychotics (OL baseline) to PP3M/PP1M in DB phase (Involvement Evaluation Questionnaire score mean ± SD change, -9.4±15.16; p < 0.001). Treatment emergent adverse events with PP3M during DB phase were similar in Latin America (study A: 24/34 [70.6%]; study B: 15/21 [71.4%]) and ROW (study A: 318/470 [67.7%]; study B: 84/139 [60.4%]) subgroups. Conclusion: PP3M was efficacious and showed no new safety concerns in patients with schizophrenia from Latin America, corroborating ROW findings. Clinical trial registration: NCT01515423, NCT01529515

ABSTRACT

Abstract Introduction: The occurrence of acute kidney injury (AKI) after ischemic stroke has been associated to a worse prognosis. There is a lack of Brazilian studies evaluating this issue. This study aimed to describe the impact of AKI after a first-ever ischemic stroke in relation to fatality rate in 30 days. Methods: This was a retrospective hospital-based cohort. We included patients who had their first ischemic stroke between January to December 2015. AKI was defined by an increase of serum creatinine in relation to baseline value at admission ≥ 0.3 mg/dL or a rise in serum creatinine level by 1.5 times the baseline value at any point in the first week after admission. We performed a univariate and multivariate analysis to evaluate the presence of AKI with fatality in 30 days. Results: The final study population (n=214) had mean age of 66.46 ± 13.73 years, 48.1% were men, the mean NIHSS was 6.33 ± 6.27 and 20 (9.3%) presented AKI. Patients with AKI were older, had a higher score on the NIHSS, and had higher creatinine values on hospital discharge. The 30-day mortality was higher in the AKI subgroup compared to non-AKI (35% vs. 6.2%, p < 0.001). AKI was an independent predictor of fatality after an ischemic stroke but limited by severity of stroke (NIHSS). Conclusion: The presence of AKI is an important complication after ischemic stroke. Despite its impact on 30-day fatality, the predictive strength of AKI was limited by the severity of stroke.


Resumo Introdução: A ocorrência de insuficiência renal aguda (IRA) após acidente vascular cerebral isquêmico (AVCI) está associada a pior prognóstico. Há uma deficiência de estudos brasileiros a respeito dessa questão. O presente estudo teve como objetivo descrever o impacto da IRA após o primeiro episódio de AVCI em relação à taxa de letalidade em 30 dias. Métodos: A presente coorte retrospectiva de base hospitalar incluiu pacientes que sofreram seu primeiro AVCI entre janeiro e dezembro de 2015. IRA foi definida por elevações da creatinina sérica em relação ao valor basal na internação ≥ 0.3 mg/dL ou aumento da creatinina sérica equivalente a 1,5 vez o valor basal em qualquer instante durante a primeira semana após a internação. Foi realizada análise univariada e multivariada para avaliar a presença de IRA com letalidade em 30 dias. Resultados: A população final do estudo (n = 214) apresentou média de idade de 66,46 ± 13,73 anos; 48,1% eram homens; a média de pontuação no NIHSS foi 6,33 ± 6,27; e 20 (9,3%) apresentaram IRA. Pacientes com IRA tinham idade mais avançada, pontuação maior na NIHSS e valores mais elevados de creatinina no momento da alta hospitalar. A mortalidade em 30 dias foi maior no subgrupo com IRA em comparação ao grupo sem IRA (35% vs. 6,2%, p < 0,001). IRA foi preditor independente de mortalidade após AVCI, porém limitado pela gravidade do acidente vascular cerebral (NIHSS). Conclusão: A presença de IRA é uma complicação importante após AVCI. Apesar de seu impacto na letalidade de 30 dias, a força preditiva da IRA foi limitada pela gravidade do AVC.

ABSTRACT

ABSTRACT Background and objectives: Anti-neutrophil cytoplasmic autoantibodies (ANCA) associated vasculitis is a small vessel vasculitis with insufficient epidemiologic estimates in the United States. We aimed to determine demographic and clinical features of ANCA associated vasculitis patients presenting to a large tertiary care referral center in Upstate New York. Design, setting, participants, and measurements: A retrospective analysis of cases with pauci-immune GN on renal biopsy and clinical diagnosis of ANCA vasculitis presenting over 11 years was conducted. Outcomes of interest were: demographics, ANCA antibody positivity, patient and renal survival, and regional trends. Results: 986 biopsies were reviewed, 41 cases met the criteria for inclusion: 18 GPA, 19 MPA, and 4 double positive (anti-GBM disease plus ANCA vasculitis). Mean age at presentation was 52.4 years (SD 23.7), 23 (56%) were male and median creatinine was 2.6 mg/dL. The median patient follow up was 77 weeks (IQR 10 - 263 weeks), with a 3-month mortality rate of 5.7% and a 1-year estimated mortality rate of 12%. Thirteen patients required hemodialysis at the time of diagnosis; 7 patients came off dialysis, with median time to renal recovery of 4.86 weeks (IQR 1.57 - 23.85 weeks). C-ANCA positivity (p < 0.001) and C-ANCA plus PR3 antibody pairing (p = 0.005) was statistically significant in GPA versus MPA. P-ANCA positivity was observed in MPA versus GPA (p = 0.02) and double positive versus GPA (p = 0.002), with P-ANCA and MPO antibody pairing in MPA versus GPA (p = 0.044). Thirty-seven of the 41 cases were referred locally, 16 cases were from within a 15-mile radius of Albany, Schenectady, and Saratoga counties. Conclusions: ANCA vasculitis is associated with end stage renal disease and increased mortality. Our study suggests the possibility of higher regional incidence of pauci-immune GN in Upstate New York. Further studies should investigate the causes of clustering of cases to specific regions.


RESUMO Introdução e objetivos: A vasculite associada a anticorpos anticitoplasma de neutrófilo (ANCA) é uma vasculite de pequenos vasos com estimativas epidemiológicas insuficientes nos Estados Unidos. Nosso objetivo foi determinar características demográficas e clínicas de pacientes com vasculite associada à ANCA, apresentando-se a um grande centro de referência de atendimento terciário em Upstate New York. Formato, cenário, participantes e medidas: Foi realizada uma análise retrospectiva dos casos de GN pauci-imune em biópsias renais e diagnóstico clínico de vasculite ANCA por mais de 11 anos. Os resultados de interesse foram: dados demográficos, positividade de anticorpos ANCA, sobrevidas renal e de pacientes e tendências regionais. Resultados: 986 biópsias foram revisadas, 41 casos preencheram os critérios de inclusão: 18 GPA, 19 PAM, e 4 duplo-positivos (doença anti-MBG com vasculite ANCA). A média de idade na apresentação foi de 52,4 anos (DP 23,7), 23 (56%) eram do sexo masculino e mediana de creatinina de 2,6 mg/dL. O acompanhamento mediano dos pacientes foi de 77 semanas (IQR 10 - 263 semanas), com uma taxa de mortalidade de 3 meses de 5,7% e uma taxa de mortalidade estimada em 1 ano de 12%. Treze pacientes necessitaram de hemodiálise no momento do diagnóstico; 7 pacientes saíram da diálise, com tempo médio para recuperação renal de 4,86 semanas (IQR 1,57 - 23,85 semanas). A positividade para C-ANCA (p < 0,001) e o pareamento de anticorpos C-ANCA mais PR3 (p = 0,005) foram estatisticamente significantes em GPA versus PAM. A positividade de P-ANCA foi observada em PAM versus GPA (p = 0,02) e duplo positivo versus GPA (p = 0,002), com pareamento de anticorpos P-ANCA e MPO em PAM versus GPA (p = 0,044). Trinta e sete dos 41 casos foram encaminhados localmente, 16 casos foram de dentro de um raio de 15 milhas dos condados de Albany, Schenectady e Saratoga. Conclusões: A vasculite por ANCA está associada à doença renal terminal e aumento da mortalidade. Nosso estudo sugere a possibilidade de maior incidência regional de GN pauci-imune no norte do estado de Nova York. Novos estudos devem investigar as causas do acúmulo de casos em regiões específicas.

ABSTRACT

RESUMEN Introducción: en el último trienio la mortalidad por cáncer mamario en el sexo femenino en Cuba disminuyó ligeramente sus tasas, sin embargo no se han realizado estudios de supervivencia por esta enfermedad en la provincia Matanzas. Objetivo: evaluar el comportamiento del tiempo de supervivencia global a los 5 años en esta serie y valorar la sobrevida en función de variables seleccionadas. Materiales y métodos: se realizó un estudio observacional descriptivo, longitudinal y retrospectivo, en el que participaron 288 mujeres diagnosticadas con cáncer de mama en la consulta de mastología del Hospital "José Ramón López Tabranes" de la provincia Matanzas, desde el 1 de Enero del 2010 hasta el 31 de Diciembre del 2015. Se utilizó el método de Kaplan Meier para determinar el tiempo de supervivencia global a los 5 años y en función de variables seleccionadas. La comparación de las diferentes curvas para las variables de exposición se realizó con la prueba de Rangos Logarítmicos (Log Rank). Se consideró estadísticamente significativo el valor del estadígrafo mayor de 1 y p < 0.05. Resultados: la supervivencia global a los 5 años fue de un 66 %. Se registran supervivencias muy por debajo de los estándares internacionales para las pacientes en estadios III (37 %) y IV (0). La supervivencia global disminuye de manera significativa en la medida en que se incrementan el número de ganglios afectados y el tamaño del tumor al momento del diagnóstico. Conclusiones: la supervivencia global a los 5 años resultó inferior a la registrada en la mayoría de los estudios internacionales consultados. Se muestra una disminución marcada de la sobrevida en pacientes con estadios clínicos avanzados de la enfermedad: (III y IV).


ABSTRACT Introduction: in the last three years, mortality rates due to breast cancer in the female sex in Cuba slightly decreased, but studies of this disease survival have not been carried out in the province of Matanzas. Objective: to evaluate the behavior of the global survival time of this series at the 5th year and to assess survival according to chosen variables. Material and method: a retrospective, longitudinal, observational descriptive study was carried out; 288 women diagnosed with breast cancer took part on it; they were diagnosed in the mastology consultation of the hospital "Jose Ramon Lopez Tabrane", province of Matanzas during the period January 1st 2010- December 31st 2015. The Kaplan-Meier method was used to determine the global survival time at the 5th year according to chosen variables. The comparison of the different curves for the exposition variables was made using the Log Rank test. The test value higher than 1 and p < 0.05 was considered statistically significant. Results: global survival at the 5th year was 66 %. There are survival rates well below the international standards for the stage III (37 %) and stage IV (0) patients. Global survival significantly decreases insofar as the number of affected ganglia and the size of the tumor at the moment of the diagnosis increase. Conclusions: global survival at the 5th year was lower than the one recorded in most of the consulted international studies. There is a remarkable decrease of survival in patients with disease advanced clinical stages: III and IV.

ABSTRACT

Abstract Purpose: To analyze the preoperative serum matrix metalloproteinase-9 (MMP-9) levels and prognosis of patients with hilar cholangiocarcinoma (HC) undergoing radical resection. Methods: Preoperative serum MMP-9 levels in patients with HC undergoing radical resection were detected by enzyme-linked immunosorbent assay (ELISA). The ROC curve assay was used to analyze the preoperative serum MMP-9 level to determine the most valuable cut-off point. The relationship between MMP-9 and clinicopathological features of HC patients was analyzed. Kaplan-Meier method was used to analyze the prognostic factors, and COX regression model was used to analyze the independent risk factors affecting prognosis. Results: Preoperative serum MMP-9 levels were significantly elevated in the death patients compared with the survival patients. The most valuable cut-off point for preoperative serum MMP-9 for prognosis was 201.93 ng/mL. Preoperative serum MMP-9 was associated with Bismuth-Corlette classification) and lymph node metastasis. Kaplan-Meier analysis showed that MMP-9, Bismuth-Corlette classification, Lymph node metastasis, Portal vein invasion, Hepatic artery invasion, Liver invasion, Incised margin, and Preoperative biliary drainage were related to prognosis. Cox regression model confirmed that hepatic artery invasion, liver invasion, incised margin, and MMP-9 have the potential to independence predicate prognosis in HC patients. Conclusion: Preoperative serum MMP-9 has high predictive value for prognosis and is an independent influencing factor for the prognosis of patients with hilar cholangiocarcinoma.

ABSTRACT

Abstract Purpose: To investigate the prognostic value of 17 platelet-based prognostic scores in patients with malignant hepatic tumors after TACE therapy. Methods: In total, 92 patients were divided into death group and survival group according to long-term follow-up results. The AUC was calculated to determine the optimal cut-off values for predicting prognosis. To determine better prognostic models, platelet-based models were analyzed separately after being showed as binary according to cut-off values. Cumulative survival rates of malignant hepatic tumors were calculated using Kaplan-Meier curves and differences were analyzed by the log-rank test. Univariate and multivariate analyses were performed to identify platelet-based prognostic scores associated with overall survival. Results: Univariate analysis showed that APGA, APRI, FIB-4, FibroQ, GUCI, King's score, Lok index, PAPAS, cirrhosis, number of tumors, vascular cancer embolus, AFP, ALP and APTT were significantly related to prognosis. A multivariate analysis showed that the APGA, number of tumors, ALP and APTT were independently associated with overall survival. Conclusion: This study showed that the APGA, a platelet-based prognostic score, was an independent marker of prognosis in patients with malignant hepatic tumors after TACE and was superior to the other platelet-based prognostic scores in terms of prognostic ability.

ABSTRACT

BACKGROUND@#Serum antinuclear antibodies (ANAs) are positive in some patients with chronic lymphocytic leukemia (CLL), but the prognostic value of ANAs remains unknown. The aim of this study was to evaluate the role of ANAs as a prognostic factor in CLL.@*METHODS@#This study retrospectively analyzed clinical data from 216 newly diagnosed CLL subjects with ANAs test from 2007 to 2017. Multivariate Cox regression analyses were used to screen the independent prognostic factors related to time to first treatment (TTFT), progression free survival (PFS) and overall survival (OS). Receiver operator characteristic curves and area under the curve (AUC) were utilized to assess the predictive accuracy of ANAs together with other independent factors for OS.@*RESULTS@#The incidence of ANAs abnormality at diagnosis was 13.9%. ANAs positivity and TP53 disruption were independent prognostic indicators for OS. The AUC of positive ANAs together with TP53 disruption was 0.766 (95% confidence interval [CI]: 0.697-0.826), which was significantly larger than that of either TP53 disruption (AUC: 0.706, 95% CI: 0.634-0.772, P = 0.034) or positive ANAs (AUC: 0.595, 95% CI: 0.520-0.668, P < 0.001) in OS prediction. Besides, serum positive ANAs as one additional parameter to CLL-international prognostic index (IPI) obtained superior AUCs in predicting CLL OS than CLL-IPI alone.@*CONCLUSION@#This study identified ANAs as an independent prognostic factor for CLL, and further investigations are needed to validate this finding.

ABSTRACT

BACKGROUND@#Pulmonary artery hypertension associated with congenital heart disease (PAH-CHD) occurs predominantly among patients with uncorrected CHD. Treatment of severe pediatric PAH-CHD remains a major intractability. This study evaluated the predictors and prognoses of children with PAH-CHD who underwent surgical correction.@*METHODS@#The data for 59 children with severe PAH-CHD who underwent surgical correction, with or without postoperative medication, between May 2011 and June 2015 at the Guangdong Provincial People's Hospital were analyzed retrospectively. A regression analysis, receiver-operating characteristic (ROC) curves, and Kaplan-Meier curves were used for survival analysis.@*RESULTS@#Fifty-nine children with severe PAH-CHD underwent heart catheterization and correction, with or without specific anti-PAH drugs postoperatively, were included in this study. The pulmonary pressure, heart function, and ending events were observed and median observation period was 49 ± 20 months. Twenty-eight patients (50%) received at least one additional anti-PAH drug after correction. The survival rate after 2 years was 91.5% (54/59); two patients were in a critical condition, and three were lost to follow-up. Twelve patients (29%) still received over one additional PAH-specific therapy at follow-up, whereas 42 (75%) had successfully stopped drug treatment. Two patients (3.5%) died and one underwent a second thoracotomy to remove the ventricular septal defect patch. Acute vasoreactivity test (AVT) criteria had limited efficacy in predicting pediatric PAH-CHD, whereas pulmonary vascular resistance (PVR) ≤ 6.65 Wood units (WU)/m or PVR/systemic vascular resistance (SVR) ≤ 0.39 during AVT indicated a good prognosis after surgical correction with an AUC of 98.3% (95% confidence interval [CI]: 96.0-100%), 98.4% (95% CI: 96.0-100%) sensitivity of 100%, 100% and specificity of 82.1%, 92.9%, respectively.@*CONCLUSIONS@#Although the criteria for positive AVT currently used are unsuitable for pediatric patients with PAH-CHD, PVR and PVR/SVR during AVT are excellent predictors of outcome in pediatric PAH-CHD. Surgery aided by anti-PAH drugs is an effective strategy and should be recommended for severe pediatric PAH-CHD with PVR ≤ 6.65 WU/m and PVR/SVR ≤ 0.39 after iloprost aerosol inhalation.

ABSTRACT

BACKGROUND@#The mortality of cardiovascular disease is constantly rising, and novel biomarkers help us predict residual risk. This study aimed to evaluate the predictive value of serum homocysteine (HCY) levels on prognosis in patients with ST-segment elevation myocardial infarction (STEMI).@*METHODS@#The 419 consecutive patients with STEMI, treated at one medical center, from March 2010 to December 2015 were retrospectively investigated. Peripheral blood samples were obtained within 24 h of admission and HCY concentrations were measured using an enzymatic cycling assay. The patients were divided into high HCY level (H-HCY) and low HCY level (L-HCY) groups. Short- and long-term outcomes were compared, as were age-based subgroups (patients aged 60 years and younger vs. those older than 60 years). Statistical analyses were mainly conducted by Student t-test, Chi-squared test, logistic regression, and Cox proportional-hazards regression.@*RESULTS@#The H-HCY group had more males (84.6% vs. 75.4%, P = 0.018), and a lower prevalence of diabetes (20.2% vs. 35.5%, P < 0.001), compared with the L-HCY group. During hospitalization, there were seven mortalities in the L-HCY group and 10 in the H-HCY group (3.3% vs. 4.8%, P = 0.440). During the median follow-up period of 35.8 (26.9-46.1) months, 33 (16.2%) patients in the L-HCY group and 48 (24.2%) in the H-HCY group experienced major adverse cardiovascular and cerebrovascular events (MACCE) (P = 0.120). History of hypertension (hazard ratio [HR]: 1.881, 95% confidence interval [CI]: 1.178-3.005, P = 0.008) and higher Killip class (HR: 1.923, 95% CI: 1.419-2.607, P < 0.001), but not HCY levels (HR: 1.007, 95% CI: 0.987-1.027, P = 0.507), were significantly associated with long-term outcomes. However, the subgroup analysis indicated that in older patients, HCY levels were significantly associated with long-term outcomes (HR: 1.036, 95% CI: 1.011-1.062, P = 0.005).@*CONCLUSION@#Serum HCY levels did not independently predict in-hospital or long-term outcomes in patients with STEMI; however, among elderly patients with STEMI, this study revealed a risk profile for late outcomes that incorporated HCY level.

ABSTRACT

PURPOSE: The purpose of this study was to explore the potential early diagnostic value of serum microRNA-381(miRNA-381) in patients with gastric cancer (GC). MATERIALS AND METHODS: Patients with advanced gastric cancer (AGC) and early gastric cancer (EGC), as well as healthy individuals, were enrolled in this study. Expression of miRNA-381 in serum was detected using real-time quantitative PCR. Electrochemiluminescence analysis was used to investigate the expression of classic tumor markers, including carbohydrate antigen (CA) 199, CA724, and carcinoembryonic antigen. Finally, receiver operating characteristic curve and Kaplan-Meier analysis were used to determine the value of miRNA-381 in clinical diagnosis of GC. RESULTS: miRNA-381 was differentially expressed among the study groups. AUC analysis showed that the sensitivity and specificity of serum miRNA-381 in the diagnosis of GC were superior to those of other tumor markers. Furthermore, low levels of miRNA-381 expression were positively correlated with lymph node metastasis and AGC. Finally, Kaplan-Meier survival analysis showed that down-regulation of miRNA-381 was associated with lymph node metastasis and the development of GC. CONCLUSION: miRNA381, which was down-regulated in GC, might be a novel early diagnosis marker for patients with GC.

ABSTRACT

PURPOSE: Local treatment has become a treatment option for patients with de novo metastatic hormone-sensitive prostate cancer (mHSPC). Subgroup analyses based on a history of cerebrovascular disease (CVD) were performed to evaluate the impact thereof on overall survival (OS) after local treatment. MATERIALS AND METHODS: A retrospective analysis was performed for 879 patients with de novo mHSPC between August 2003 and November 2016. Patients were stratified according to prior CVD history and the type of initial treatment: androgen-deprivation therapy (ADT) alone versus local treatment consisting of radical prostatectomy (RP) or radiation therapy (RT) with ADT, with or without metastasis-directed therapy. The primary outcome was OS assessed by Kaplan-Meier analysis and Cox-regression models. RESULTS: Of 879 patients, 660 (75.1%) men underwent ADT alone, and 219 (24.9%) men underwent RP or RT with ADT, with or without metastasis-directed therapy. The median follow-up was 38 months. Multivariable analysis showed CVD history to be associated with a higher risk of overall mortality (p=0.001). In the overall cohort and in patients without a history of CVD, patients who underwent local treatment exhibited higher OS than men who received ADT alone (all p<0.001). However, the survival benefit conferred by local treatment was not seen in patients with a history of CVD (p=0.324). OS was comparable between patients who received RP and RT (p=0.521). CONCLUSION: Local treatment with or without metastasis-directed therapy may provide OS advantages for mHSPC patients without a history of CVD. Further prospective studies are needed to address these important concerns.

ABSTRACT

BACKGROUND@#High on-treatment platelet reactivity (HTPR) has been suggested as a risk factor for patients with ischemic vascular disease. We explored a predictive model of platelet reactivity to clopidogrel and the relationship with clinical outcomes.@*METHODS@#A total of 441 patients were included. Platelet reactivity was measured by light transmittance aggregometry after receiving dual antiplatelet therapy. HTPR was defined by the consensus cutoff of maximal platelet aggregation >46% by light transmittance aggregometry. CYP2C19 loss-of-function polymorphisms were identified by DNA microarray analysis. The data were compared by binary logistic regression to find the risk factors. The primary endpoint was major adverse clinical events (MACEs), and patients were followed for a median time of 29 months. Survival curves were constructed with Kaplan-Meier estimates and compared by log-rank tests between the patients with HTPR and non-HTPR.@*RESULTS@#The rate of HTPR was 17.2%. Logistic regression identified the following predictors of HTPR: age, therapy regimen, body mass index, diabetes history, CYP2C192, or CYP2C193 variant. The area under the curve of receiver operating characteristic for the HTPR predictive model was 0.793 (95% confidence interval: 0.738-0.848). Kaplan-Meier analysis showed that patients with HTPR had a higher incidence of MACE than those with non-HTPR (21.1% vs. 9.9%; χ = 7.572, P = 0.010).@*CONCLUSIONS@#Our results suggest that advanced age, higher body mass index, treatment with regular dual antiplatelet therapy, diabetes, and CYP2C192 or CYP2C193 carriers are significantly associated with HTPR to clopidogrel. The predictive model of HTPR has useful discrimination and good calibration and may predict long-term MACE.

ABSTRACT

BACKGROUND@#It is currently unclear if fibrinogen is a risk factor for adverse events in patients receiving percutaneous coronary intervention (PCI) or merely serves as a marker of pre-existing comorbidities and other causal factors. We therefore investigated the association between fibrinogen levels and 2-year all-cause mortality, and compared the additional predictive value of adding fibrinogen to a basic model including traditional risk factors in patients receiving contemporary PCI.@*METHODS@#A total of 6293 patients undergoing PCI with measured baseline fibrinogen levels were enrolled from January to December 2013 in Fuwai Hospital. Patients were divided into three groups according to tertiles of baseline fibrinogen levels: low fibrinogen, <2.98 g/L; medium fibrinogen, 2.98 to 3.58 g/L; and high fibrinogen, ≥3.58 g/L. Independent predictors of 2-year clinical outcomes were determined by multivariate Cox proportional hazards regression modeling. The increased discriminative value of fibrinogen for predicting all-cause mortality was assessed using the C-statistic and integrated discrimination improvement (IDI).@*RESULTS@#The 2-year all-cause mortality rate was 1.2%. It was significantly higher in the high fibrinogen compared with the low and medium fibrinogen groups according to Kaplan-Meier analyses (1.7% vs. 0.9% and 1.7% vs. 1.0%, respectively; log-rank, P = 0.022). Fibrinogen was significantly associated with all-cause mortality according to multivariate Cox regression (hazard ratio 1.339, 95% confidence interval: 1.109-1.763, P = 0.005), together with traditional risk factors including age, sex, diabetes mellitus, left ventricular ejection fraction, creatinine clearance, and low-density lipoprotein cholesterol. The area under the curve for all-cause mortality in the basic model including traditional risk factors was 0.776, and this value increased to 0.787 when fibrinogen was added to the model (IDI = 0.003, Z = 0.140, P = 0.889).@*CONCLUSIONS@#Fibrinogen is associated with 2-year all-cause mortality in patients receiving PCI, but provides no additional information over a model including traditional risk factors.

ABSTRACT

OBJECTIVE@#To explore the expression patterns of transcription factor SOX12 in lung adenocarcinoma and its significance in the diagnosis and prognosis of the malignancy.@*METHODS@#Large cancer genome databases were used to analyze SOX12 expression level in lung adenocarcinoma. Immunohistochemistry (IHC) and semiquantitative PCR were used to detect the expression of SOX12 in 36 specimens of lung adenocarcinoma tissues, 15 adjacent tissues and 21 normal lung tissues. The prognostic value of SOX12 in lung adenocarcinoma and lung squamous cell carcinoma were analyzed using Kaplan-Meier Plotter database, and the relationship between SOX12 expression and the overall survival (OS) and progression free survival (PPS) of the patients were analyzed.@*RESULTS@#Analysis of TCGA database and GEO (GSE40419) database showed that SOX12 expression levels were significantly higher in in lung adenocarcinoma than in normal lung tissues ( < 0.001). The results of IHC and semiquantitative PCR revealed that SOX12 was expressed at significantly higher levels in lung adenocarcinoma than in normal lung tissues ( < 0.001). Kaplan-Meier survival analysis showed that patients with lung adenocarcinoma positive for SOX12 had a significantly shorter OS and PPS time than those negative for SOX12 ( < 0.05), but SOX12 positivity did not significantly affect OS and PPS of patients with lung squamous cell carcinoma.@*CONCLUSIONS@#High expression levels of SOX12 in lung adenocarcinoma are significantly associated with a poor OS of the patients, suggesting the value of SOX12 to assist in early diagnosis and prognostic evaluation of lung adenocarcinoma.

ABSTRACT

BACKGROUND: Several conflicting studies exist on the relationship between body mass index (BMI) and depression. We investigated the effect of BMI on the development of depression in adults aged 45 years and older using the Korean Longitudinal Study of Aging Study (KLoSA).METHODS: The data from the wave 1 (2006), wave 2 (2008), wave 3 (2010), wave 4 (2012), and wave 5 (2014) database of the Korean Longitudinal Study on Aging (KLoSA) were analyzed. Depression was assessed using the Center for Epidemiologic Studies Depression Scale-10. To investigate the relationship between BMI and depression, ANOVA and chi-square test was used. Kaplan-Meier survival curves were generated, and Cox proportional hazard regression modeling was used to estimate the risk of depression according to obesity status, by controlling for age, sex, and health-related, lifestyle, and socioeconomic variables.RESULTS: This study included 6,811 individuals who were not found to have depression in the first survey. The incidence of depression was the highest in the underweight group (underweight, 74.3%; normal, 63.1%; overweight, 59.5%; obese, 63.0%; severe obese, 59.9%, P < 0.001). The risk of depression was significantly lower in the overweight and severe obese groups than in the underweight group after adjusting for age, sex, and demographic, social, and physical factors (overweight: hazard ratio [HR]=0.872, 95% confidence interval [CI]=0.775–0.981; severe obese: HR=0.791, 95% CI=0.648–0.966).CONCLUSION: The incidence of depression was the highest in the underweight group. The risk of depression was higher in the underweight group than in the overweight and severe obese groups.

ABSTRACT

PURPOSE: Breast cancer is the most frequently diagnosed malignancy in women worldwide. MicroRNAs (miRNAs) are thought to serve as potential biomarkers in various cancers, including breast cancer. METHODS: We evaluated the miRNA expression profiles in 1,083 breast cancer samples and 104 normal breast tissues from The Cancer Genome Atlas database. We used the edgeR package of R software to analyze the differentially expressed miRNAs in normal and cancer tissues, and screened survival-related miRNAs by Kaplan-Meier analysis. A receiver operating characteristic curve was generated to evaluate the accuracy of these miRNAs as molecular markers for breast cancer diagnosis. Furthermore, the functional role of these miRNAs was verified using cell experiments. Targets of candidate miRNAs were predicted using 9 online databases, and Gene Ontology (GO) functional annotation and pathway analyses were conducted using Database for Annotation, Visualization and Integrated Discovery online tool. RESULTS: A total of 68 miRNAs showed significantly different expression patterns between the groups (p < 0.001), and 13 of these miRNAs were significantly associated with poor survival (p < 0.05). Three miRNAs with high specificity and sensitivity, namely, miR-148b-3p, miR-190b, and miR-429, were selected. In vitro experiments showed that the overexpression of these 3 miRNAs significantly promoted the proliferation and migration of MDA-MB-468 and T47D cells and reduced the apoptosis of T47D cells. GO and pathway enrichment analyses revealed that the targets of these dysregulated miRNAs were involved in many critical cancer-related biological processes and pathways. CONCLUSION: The miR-148b-3p, miR-190b, and miR-429 may serve as potential diagnostic and prognostic markers for breast cancer. This study demonstrated the roles of these 3 miRNAs in the initiation and progression of breast cancer.

ABSTRACT

ABSTRACT Objective: To validate the Pulmonary Embolism Severity Index (PESI), which was developed for risk stratification after acute pulmonary embolism (PE), for use in Brazil. Methods: This was a single-center retrospective study involving patients admitted to the emergency department with acute PE. The original and simplified versions of the PESI were calculated using hospital admission data from medical records. The outcome measure was the overall 30-day mortality rate. Results: We included 123 patients. The mean age was 57 ± 17 years, and there was a predominance of females, who accounted for 60% of the cohort. There were 28 deaths, translating to an overall 30-day mortality rate of 23%. In the cluster analysis by risk class, overall 30-day mortality was 2.40% for classes I-II, compared with 20.00% for classes III-IV-V (relative risk [RR] = 5.9; 95% CI: 1.88-18.51; p = 0.0002). When we calculated overall 30-day mortality using the simplified version (0 points vs. ≥ 1 point), we found it to be 3.25% for 0 points and 19.51% for ≥ 1 point (RR = 2.38; 95% CI: 0.89-6.38; p = 0.06). Using the original version, a survival analysis showed that risk classes I and II presented similar Kaplan-Meier curves (p = 0.59), as did risk classes III, IV, and V (p = 0.25). However, the curve of the clusters based on the original version, showed significantly higher mortality in the III-IV-V classes than in the I-II classes (RR = 7.63; 95% CI: 2.29-25.21; p = 0.0001). The cluster analysis based on the original version showed a greater area under the ROC curve than did the analysis based on the simplified version (0.70; 95% CI: 0.62-0.77 vs. 0.60; 95% CI: 0.51-0.67; p = 0.05). Conclusions: The PESI adequately predicted the prognosis after acute PE in this sample of the population of Brazil. The cluster analysis based on the original version is the most appropriate analysis in this setting.


RESUMO Objetivo: Pulmonary Embolism Severity Index (PESI) foi desenvolvido para a estratificação de risco após tromboembolia pulmonar (TEP) aguda. Nosso objetivo foi validá-lo para uso no Brasil. Métodos: Estudo retrospectivo unicêntrico incluindo pacientes com TEP admitidos numa unidade de emergência. O PESI (versão original e simplificada) foi calculado utilizando-se dados dos prontuários na admissão hospitalar. O desfecho analisado foi mortalidade geral em 30 dias (MG30). Resultados: Foram incluídos 123 pacientes, com média de idade de 57 ± 17 anos, predomínio do sexo feminino (60%) e MG30 de 28 óbitos (23%). Na análise agrupada, a MG30 (classes I-II vs. III-IV-V) foi de 2,40% vs. 20,00% (risco relativo [RR] = 5,9; IC95%: 1,88-18,51; p = 0,0002). A MG30 na versão simplificada (0 vs. ≥ 1 ponto) foi de 3,25% vs. 19,51% (RR = 2,38; IC95%: 0,89-6,38; p = 0,06). A análise da sobrevida mostrou que as curvas de Kaplan-Meier foram semelhantes nas classes I e II (p = 0,59) e entre as classes III, IV e V (p = 0,25). A curva da versão original agrupada mostrou que a MG30 foi significativamente maior no grupo III-IV-V que no grupo I-II (RR = 7,63; IC95%: 2,29-25,21; p = 0,0001). A análise agrupada da versão original mostrou área sob a curva ROC maior que a da versão simplificada (0,70; IC95%: 0,62-0,77 vs. 0,60; IC95%: 0,51-0,67; p = 0,05). Conclusões: O PESI mensurou adequadamente o prognóstico de MG30 após TEP aguda nesta amostra da população brasileira. A utilização da versão original agrupada foi a mais adequada nesse cenário.

ABSTRACT

RESUMO Objetivo: determinar a expressão de neurotrofinas e seus receptores tirosina quinases em pacientes com osteossarcoma (OS) e sua correlação com desfechos clínicos. Métodos: biópsias de tumores primários de pacientes com OS tratados em uma única instituição, consecutivamente, entre 2002 e 2015, foram analisados através de imuno-histoquímica para expressão de receptores de tirosina quinase A e B (TrKA e TrKB), fator de crescimento neural (NGF) e fator neurotrófico derivado do cérebro (BDNF). De forma independente, dois patologistas classificaram os marcadores de imuno-histoquímica como negativos (negativos e focais fracos) ou positivos (moderado focal/difuso ou forte focal/difuso). Resultados: foram analisados dados de 19 pacientes (10 do sexo feminino e 9 do masculino) com mediana de idade de 12 anos (5 a 17,3 anos). Dos tumores, 83,3% estavam localizados em membros inferiores e 63,2% dos pacientes eram metastáticos ao diagnóstico. A sobrevida global em cinco anos foi de 55,3%. BDNF foi positivo em 16 pacientes (84%) e NGF em 14 pacientes (73%). TrKA e TrKB apresentaram coloração positiva em quatro (21,1%) e oito (42,1%) pacientes, respectivamente. A análise de sobrevida não demonstrou diferença significativa entre receptores TrK e neurotrofinas. Conclusão: amostras de OS primário expressam neurotrofinas e receptores TrK através de imuno-histoquímica. Estudos futuros podem auxiliar na identificação do papel das mesmas na patogênese do OS e determinar se há possível correlação prognóstica.


ABSTRACT Objective: to determine the expression of neurotrophins and their tyrosine-kinase receptors in patients with osteosarcoma (OS) and their correlation with clinical outcomes. Methods: we applied immunohistochemistry to biopsy specimens of patients consecutively treated for primary OS at a single institution between 2002 and 2015, analyzing them for expression receptors of tyrosine kinase A and B (TrKA and TrKB), neural growth factor (NGF) and brain derived neurotrophic factor (BDNF). Independently, two pathologists classified the immunohistochemical markers as negative (negative or weak focal) or positive (moderate focal/diffuse or strong focal/diffuse). Results: we analyzed data from 19 patients (10 females and 9 males), with median age of 12 years (5 to 17.3). Tumors' location were 83.3% in the lower limbs, and 63.2% of patients had metastases at diagnosis. Five-year overall survival was 55.3%. BDNF was positive in 16 patients (84%) and NGF in 14 (73%). TrKA and TrKB presented positive staining in four (21,1%) and eight (42,1%) patients, respectively. Survival analysis showed no significant difference between TrK receptors and neurotrophins. Conclusion: primary OS samples express neurotrophins and TrK receptors by immunohistochemistry. Future studies should explore their role in OS pathogenesis and determine their prognostic significance in larger cohorts.

ABSTRACT

RESUMO Objetivo A pneumonia pneumocócica é uma causa significativa de morbimortalidade entre adultos. Desta maneira, o objetivo principal deste estudo foi avaliar a mortalidade intra-hospitalar e os custos relacionados à doença adquirida em adultos. Métodos Este estudo transversal utilizou prontuários de pacientes adultos com pneumonia pneumocócica internados em um hospital universitário no Brasil, de outubro de 2009 a abril de 2017. Todos os pacientes com idade ≥ 18 anos e diagnosticados com pneumonia pneumocócica foram incluídos. Dados como os fatores de risco, a internação em unidade de terapia intensiva, o tempo de internação, a mortalidade hospitalar e os custos diretos e indiretos foram analisados. Resultados No total, 186 pacientes foram selecionados. A taxa média de mortalidade intra-hospitalar foi de 18% para adultos com idade < 65 anos e 23% para os idosos (≥ 65 anos). A pneumonia pneumocócica bacterêmica acometeu 20% dos pacientes em ambos os grupos, principalmente por doença respiratória crônica (OR ajustada: 3,07; IC95%: 1,23‐7,65; p < 0,01). Após levantamento das internações ocorridas no período de sete anos de tratamento, verificou-se que os custos diretos e indiretos totais anuais foram de US$ 28.188 para adultos < 65 anos (US$ 1.746 per capita) e US$ 16.350 para os idosos (US$ 2.119 per capita). Conclusão A pneumonia pneumocócica continua sendo uma importante causa de morbimortalidade entre adultos, afetando significativamente os custos diretos e indiretos. Esses resultados sugerem a necessidade de estratégias de prevenção para todos os adultos, especialmente para pacientes com doenças respiratórias crônicas.


ABSTRACT Objective Pneumococcal pneumonia is a significant cause of morbidity and mortality among adults. The study's main aim was to evaluate the in-hospital mortality and related costs of community-acquired pneumococcal pneumonia in adults. Methods This cross-sectional study used medical records of adult patients with pneumococcal pneumonia hospitalized in a university hospital in Brazil from October 2009 to April 2017. All patients aged ≥ 18 years diagnosed with pneumococcal pneumonia were included. Risk factors, intensive care unit admission, length of hospital stay, in-hospital mortality, and direct and indirect costs were analyzed. Results In total, 186 patients were selected. The mean in-hospital mortality rate was 18% for adults aged < 65 years and 23% for the elderly (≥ 65 years). Bacteremic pneumococcal pneumonia affected 20% of patients in both groups, mainly through chronic respiratory disease (adjusted OR: 3.07, 95% CI: 1.23-7.65, p < 0.01). Over 7 years, annual total direct and indirect costs were USD 28,188 for adults < 65 years (USD 1,746 per capita) and USD 16,350 for the elderly (USD 2,119 per capita). Conclusion Pneumococcal pneumonia remains an important cause of morbidity and mortality among adults, significantly affecting direct and indirect costs. These results suggest the need for prevention strategies for all adults, especially for patients with chronic respiratory diseases.
