ABSTRACT

Resumo Fundamento O paradoxo do fumante tem sido motivo de debate para pacientes com infarto agudo do miocárdio (IM) há mais de duas décadas. Embora haja muitas evidências demonstrando que não existe tal paradoxo, publicações defendendo desfechos melhores em fumantes pós-IM ainda são lançadas. Objetivo Explorar o efeito do fumo na mortalidade de longo prazo após infarto do miocárdio por elevação de ST (STEMI). Métodos Este estudo incluiu pacientes com STEMI que foram diagnosticados entre 2004 e 2006 em três centros terciários. Os pacientes foram categorizados de acordo com a exposição ao tabaco (Grupo 1: não-fumantes; Grupo 2: <20 pacotes*anos; Grupo 3: 2-040 pacotes*anos; Grupo 4: >40 pacotes*anos). Um modelo de regressão de Cox foi utilizado para estimar os riscos relativos para mortalidade de longo prazo. O valor de p <0,05 foi considerado como estatisticamente significativo. Resultados Trezentos e treze pacientes (201 fumantes e 112 não-fumantes) foram acompanhados por um período médio de 174 meses. Os fumantes eram mais novos (54±9 vs. 62±11, p: <0,001), e a presença de fatores de risco cardiometabólicos foi mais prevalente entre os não-fumantes. Uma análise univariada do impacto do hábito de fumar na mortalidade revelou uma curva de sobrevivência melhor no Grupo 2 do que no Grupo 1. Porém, após ajustes para fatores de confusão, observou-se que os fumantes tinham um risco de morte significativamente maior. O risco relativo tornou-se maior de acordo com a maior exposição (Grupo 2 vs. Grupo 1: RR: 1,141; IC95%: 0,599 a 2.171; Grupo 3 vs. Grupo 1: RR: 2,130; IC95%: 1,236 a 3,670; Grupo 4 vs. Grupo 1: RR: 2,602; IC95%: 1,461 a 4,634). Conclusão O hábito de fumar gradualmente aumenta o risco de mortalidade por todas as causas após STEMI.


Abstract Background The smoking paradox has been a matter of debate for acute myocardial infarction patients for more than two decades. Although there is huge evidence claiming that is no real paradox, publications supporting better outcomes in post-MI smokers are still being released. Objective To explore the effect of smoking on very long-term mortality after ST Elevation myocardial infarction (STEMI). Methods This study included STEMI patients who were diagnosed between the years of 2004-2006 at three tertiary centers. Patients were categorized according to tobacco exposure (Group 1: non-smokers; Group 2: <20 package*years users, Group 3: 20-40 package*years users, Group 4: >40 package*years users). A Cox regression model was used to estimate the relative risks for very long-term mortality. P value <0.05 was considered as statistically significant. Results There were 313 patients (201 smokers, 112 non-smokers) who were followed-up for a median period of 174 months. Smokers were younger (54±9 vs. 62±11, p: <0.001), and the presence of cardiometabolic risk factors were more prevalent in non-smokers. A univariate analysis of the impact of the smoking habit on mortality revealed a better survival curve in Group 2 than in Group 1. However, after adjustment for confounders, it was observed that smokers had a significantly increased risk of death. The relative risk became higher with increased exposure (Group 2 vs. Group 1; HR: 1.141; 95% CI: 0.599 to 2.171, Group 3 vs Group 1; HR: 2.130; 95% CI: 1.236 to 3.670, Group 4 vs Group 1; HR: 2.602; 95% CI: 1.461 to 4.634). Conclusion Smoking gradually increases the risk of all-cause mortality after STEMI.

ABSTRACT

Diabetic retinopathy is a complication of diabetes, caused by high blood sugar levels damaging the eye. Globally, diabetic retinopathy affects more than 103.12 million people. Diabetic retinopathy is among the leading causes of vision loss at the global level, including in Ethiopia. Therefore, the study aimed to assess the time to develop diabetic retinopathy and identify factors associated with diabetic retinopathy among diabetes patients. METHODS: A retrospective study was conducted from September 1, 2021, to January 30, 2022. Data was collected using semi structured questionnaire. The Cox proportional hazard model were used to determine the median time to develop diabetic retinopathy and identify predictors of diabetic retinopathy. Data was analyzed using R software. RESULTS: A total of 373 diabetes patients were included in this study. The prevalence of diabetic retinopathy was 41.3%. The median time was 41 months, ranging from 39 to 73 months. Elder age (HR=3.17, 95%CI: 1.53, 6.58), being male (HR=2.34, 95%CI: 1.35,6.15), previous family history of diabetes (HR=4.16, 95%CI: 2.19, 8.37), longer duration of diabetes (HR=2.86, 95%CI: 1.41, 5.31) received only insulin therapy (HR=3.91, 95%CI: 1.36, 7.94), and high systolic blood pressure (HR=2.32; 95%CI: 1.12, 4.39) were statistically significant factors related to development of diabetes retinopathy. CONCLUSIONS: More than half of diabetic patinets in this study were developed retinopathy diabetes within a few months of being diagnosed. As a result, we advocate that the best way to preserve our vision from diabetic retinopathy is to maintain our diabetes under control, and the high-risk population receive early screening for diabetes

ABSTRACT

OBJECTIVE@#To explore the risk factors for recurrence in first-episode ischemic stroke survivors and establish a model for predicting stroke recurrence using a nomogram.@*METHODS@#We collected the data from a total of 821 first-episode ischemic stroke survivors admitted in the Department of Neurology, West China Hospital, Sichuan University from January, 2010 to December, 2018. R software was used for random sampling of the patients, and 70% of the patients were included in the training set to establish the prediction model and 30% were included in the validation set. Cox proportional risk regression model was used to analyze the factors affecting stroke recurrence, and R software rms package was used to construct the histogram and establish the visual prediction model. C-index and calibration curve were used to evaluate the performance of the model for predicting stroke occurrence.@*RESULTS@#Among the 821 survivors, the recurrence rate was 16.81% at 3 years and 19.98% at 5 years. Multivariate analysis of the training set by Cox regression model showed that an age over 65 years (HR= 2.596, P=0.024), an age of 45-64 years (HR=2.510, P=0.006), a mRS score beyond 3 (HR=2.284, P=0.004) and a history of coronary heart disease (HR=1.353, P=0.034) were all risk factors for stroke recurrence. The C-indexes of the nomogram for the 3-and 5-year relapse prediction model were 0.640 and 0.671, respectively.@*CONCLUSION@#Age, mRS score and peripheral vascular disease are the factors affecting stroke recurrence in first-episode ischemic stroke survivors, and the nomogram has a high discrimination and predictive power for predicting ischemic stroke recurrence.

ABSTRACT

OBJECTIVE@#To explore the influence of positive/negative effectivity on the mortality risk of the Chinese elderly.@*METHODS@#Using the latest four surveys data of Chinese longitudinal healthy longevity survey in 2008, 2012, and 2014, as well as 2018 and selecting 10 993 elderly people who were aged 65 and above as research objects, this paper compared the positive/negative effectivity status and differences of the elderly in different gender and age groups. And then this paper analyzed the effect of positive/negative effectivity on elderly people' s mortality risk by constructing Cox proportional hazards model.@*RESULTS@#Compared with the female elderly, the male elderly had lower negative effectivity and higher positive effectivity. With the increase of age, the negative effectivity of the elderly increased, while the positive effectivity decreased. The results showed that after adjusting for the basic demographic characteristics, health status and living habits of the respondents in the baseline survey, in the positive effectivity dimension, "clean preference" (HR=0.922, 95%CI: 0.889-0.956), "autonomy" (HR=0.933, 95%CI: 0.914-0.952) and "sense of youth" (HR=0.948, 95%CI: 0.927-0.969), had a protective effect on the mortality risk of the elderly, while in the dimension of "open-minded view", there was no significant difference in the mortality risk of the elderly with different answers. In the negative effecti-vity dimension, "tension and fear" (HR=1.039, 95%CI: 1.014-1.065), "loneliness" (HR=1.053, 95%CI: 1.029-1.079) and "uselessness" had a harmful effect on the mortality risk of the elderly. The more positive effectivity, the lower the mortality risk of the elderly (HR=0.967, 95%CI: 0.956-0.978), while the more negative effectivity, the higher the mortality risk of the elderly (HR=1.024, 95%CI: 1.013-1.035).@*CONCLUSION@#The negative effectivity of the elderly in all dimensions may increase the mortality risk of elderly people. We ought to dredge the negative emotions of the elderly in time. In the health promotion of the elderly, we should also pay attention to the encouragement of positive effectivity in all dimensions, which requires the joint efforts of families, communities and governments.

ABSTRACT

BACKGROUND@#We investigated whether family histories of herpes zoster (HZ) are associated with the risk of incident HZ in a Japanese population.@*METHODS@#A total of 12,522 Japanese residents aged ≥50 years in Shozu County participated in the baseline survey between December 2008 and November 2009 (the participation rate = 72.3%). They were interviewed at baseline by research physicians regarding the registrants' history of HZ. A self-administered questionnaire survey was conducted to evaluate the potential confounding factors. 10,530 participants without a history of HZ were followed up to ascertain the incidence of HZ during 3-years follow-up until the end of November 2012 with Japanese nationals. We estimated hazard ratios (HRs) of incident HZ according to first-degree family histories using the Cox proportional hazard regression after adjusting for age, sex, and other potential confounding factors.@*RESULTS@#Compared to no HZ history of each family member, a history of brother or sister was associated with a higher risk of incident HZ while histories of father and mother were not. The multivariable HR (95%CI) of incident HZ for a history of brother or sister was 1.67 (1.04-2.69). When comparing to no family histories of all first-degree relatives, the multivariable HRs (95%CIs) were 1.34 (0.77-2.34) for a history of brother or sister alone, but 4.81 (1.78-13.00) for a history of mother plus brother or sister. As for the number of family histories, the multivariable HRs (95%CIs) were 1.08 (0.76-1.54) for one relative (father, mother, or brother or sister) and 2.75 (1.13-6.70) for two or more relatives.@*CONCLUSION@#Family histories of mother plus brother or sister and two or more first-degree relatives were associated with a higher risk of incident HZ.

ABSTRACT

Objective: To describe gastric cancer incidence in Suzhou cohort, explore the environmental risk factors of gastric cancer in Suzhou, and provide appropriate suggestions for gastric cancer prevention and control. Methods: The participants were from the Suzhou cohort of China Kadoorie Biobank. Baseline survey was conducted from 2004 to 2008, followed by long-term follow-up until December 31, 2013. After the exclusion of those who had been previously diagnosed with peptic ulcer and malignant tumor reported at baseline survey and gastric cancer within six months after enrollment, a total of 50,136 participants were included. Cox proportional risk models were used to identify risk factors of gastric cancer and their hazard ratios in Suzhou. The effect modifications of gender on the association between risk factors and gastric cancer were analyzed. Results: In the follow-up of 7.19 years (median), 374 gastric cancers cases occurred. The standardized incidence was 94.57 per 100 000 person-years. Multivariate Cox proportional risk model analysis found that age (10 years old as a age group, HR=2.20, 95%CI: 1.92-2.53, P<0.001), current smoking (HR=1.84, 95%CI: 1.10-3.07 P=0.020), consumption of preserved vegetables weekly (HR=2.28, 95%CI: 1.28-4.07, P=0.005) and daily (HR=2.05, 95%CI: 1.16-3.61, P=0.013) were risk factors for gastric cancer. Female (HR=0.44, 95%CI: 0.25-0.76, P=0.003) and refrigerator use (10 years as a limit, HR=0.85, 95%CI: 0.74-0.97, P=0.016) were protective factors for gastric cancer. Further analysis showed that there was heterogeneity between males and females in the association between refrigerator use years and the incidence of gastric cancer (P=0.009), and there was an interaction effect between gender and refrigerator use on the incidence of gastric cancer (P=0.010). Conclusions: The incidence of gastric cancer in Suzhou cohort was high. The risk factors of gastric cancer varied. There was a synergistic interaction effect between gender and refrigerator use years on the incidence of gastric cancer.

ABSTRACT

Objective: To systematically introduce the design of case-cohort study and the statistical methods of relative risk estimation and their application in the design. Methods: First, we introduced the basic principles of case-cohort study design. Secondly, Prentice's method, Self-Prentice method and Barlow method were described in the weighted Cox proportional hazard regression models in detail, finally, the data from the Shanghai Women's Health Study were used as an example to analyze the association between obesity and liver cancer incidence in the full cohort and case-cohort sample, and the results of parameters from each method were compared. Results: Significant association was observed between obesity and risk for liver cancer incidence in women in both the full cohort and the case-cohort sample. In the Cox proportional hazard regression model, the partial regression coefficients of the full cohort and the case-cohort sample fluctuated with the adjustment of confounding factors, but the hazard ratio estimates of them were close. There was a difference in the standard error of the partial regression coefficient between the full cohort and the case-cohort sample. The standard error of the partial regression coefficient of the case-cohort sample was larger than that of the full cohort, resulting in a wider 95% confidence interval of the relative risk. In the weighted Cox proportional hazard regression model, the standard error of the partial regression coefficient of Prentice's method was closer to the parameter estimates from full cohort than Self-Prentice method and Barlow method, and the 95% confidence interval of hazard ratio was closer to that of the full cohort. Conclusions: Case-cohort design could yield parameter results closer to the full cohort by collecting and analyzing data from sub-cohort members and patients with the disease, and reduce sample size and improve research efficiency. The results suggested that Prentice's method would be preferred in case-cohort design.

ABSTRACT

Objective: To analyze the efficacy of sinonasal adenoid cystic carcinoma (ACC) with perineural invasion (PNI), and explore the prognostic value of PNI on sinonasal adenoid cystic carcinoma. Methods: The clinical data of 105 patients with sinonasal ACC admitted to Cancer Hospital, Chinese Academy of Medical Sciences from January 2000 to December 2016 were retrospectively reviewed. All patients were restaged according to American Joint Committee on Cancer 8th edition. Follow-up visits were conducted to obtain information of treatment failure and survival outcome. The Log rank test was used for univariate analysis of prognostic factors, and Cox regression model was used for multivariate prognostic analysis. Results: The maxillary sinus (n=59) was the most common primary site, followed by the nasal cavity (n=38). There were 93 patients with stage Ⅲ-Ⅳ. The treatment modalities included surgery alone (n=14), radiotherapy alone (n=13), preoperative radiotherapy plus surgery (n=10), and surgery plus postoperative radiotherapy (n=68). The median follow-up time was 91.8 months, the 5-year local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) rates were 72.6%, 73.0%, 52.9% and 78.0%, respectively. There were 33 patients (31.4%) with PNI-positive. The 5-year DMFS, PFS, and OS rates of PNI-positive group were 53.7%, 29.4% and 56.5%, respectively, which were significantly inferior to those of PNI-negative group (80.8%, 63.0% and 86.8%, respectively, P<0.05), while there was no significant difference in the 5-year LC rate between both groups (64.5% vs 76.5%, P=0.273). The multivariate Cox regression analysis showed PNI was one of the poor prognostic factors of DMFS (HR=3.514, 95%CI: 1.557-7.932), PFS (HR=2.562, 95%CI: 1.349-4.866) and OS (HR=2.605, 95%CI: 1.169-5.806). Among patients with PNI-positive, the 5-year LC, PFS and OS rates of patients received surgery combined with radiotherapy were 84.9%, 41.3% and 72.7%, respectively, which were significantly higher than 23.3%, 10.0% and 26.7% of patients receiving surgery or radiotherapy alone (P<0.05). Conclusion: The presence of PNI increases the risk of distant metastasis in patients with sinonasal ACC. Compared with patients with PNI-negative, the prognosis of patients with PNI-positive is relatively poor, and surgery combined with radiotherapy for PNI-positive sinonasal ACC results in good clinical outcomes.

ABSTRACT

To reduce treatment-related side effects in low-risk prostate cancer (PCa), both focal therapy and deferred treatments, including active surveillance (AS) and watchful waiting (WW), are worth considering over radical prostatectomy (RP). Therefore, this study aimed to compare long-term survival outcomes between focal therapy and AS/WW. Data were obtained and analyzed from the Surveillance, Epidemiology, and End Results (SEER) database. Patients with low-risk PCa who received focal therapy or AS/WW from 2010 to 2016 were included. Focal therapy included cryotherapy and laser ablation. Multivariate Cox proportional hazards models were used to compare overall mortality (OM) and cancer-specific mortality (CSM) between AS/WW and focal therapy, and propensity score matching (PSM) was performed to reduce the influence of bias and unmeasured confounders. A total of 19 292 patients with low-risk PCa were included in this study. In multivariate Cox proportional hazards model analysis, the risk of OM was higher in patients receiving focal therapy than those receiving AS/WW (hazard ratio [HR] = 1.35, 95% confidence interval [CI]: 1.02-1.79, P = 0.037), whereas no significant difference was found in CSM (HR = 0.98, 95% CI: 0.23-4.11, P = 0.977). After PSM, the OM and CSM of focal therapy and AS/WW showed no significant differences (HR = 1.26, 95% CI: 0.92-1.74, P = 0.149; and HR = 1.26, 95% CI: 0.24-6.51, P = 0.782, respectively). For patients with low-risk PCa, focal therapy was no match for AS/WW in decreasing OM, suggesting that AS/WW could bring more overall survival benefits.

ABSTRACT

Objective To investigate the relationship between the expression of glutathione peroxidase(GPX)genes and the clinical prognosis in glioma patients,and to construct and evaluate the model for predicting the prognosis of glioma. Methods The clinical information and GPX expression of 663 patients,including 153 patients of glioblastoma(GBM)and 510 patients of low-grade glioma(LGG),were obtained from The Cancer Genome Atlas(TCGA)database.The relationship between GPX expression and patient survival was analyzed.The key GPX affecting the prognosis of glioma was screened out by single- and multi-factor Cox's proportional-hazards regression models and validated by least absolute shrinkage and selection operator(Lasso)regression.Finally,we constructed the model for predicting the prognosis of glioma with the screening results and then used concordance index and calibration curve respectively to evaluate the discrimination and calibration of model. Results Compared with those in the control group,the expression levels of GPX1,GPX3,GPX4,GPX7,and GPX8 were up-regulated in glioma patients(all P<0.001).Moreover,the expression levels of other GPX except GPX3 were higher in GBM patients than in LGG patients(all P<0.001).The Kaplan-Meier curves showed that the progression-free survival of GBM with high expression of GPX1(P=0.013)and GPX4(P=0.040),as well as the overall survival,disease-specific survival,and progression-free survival of LGG with high expression of GPX1,GPX7,and GPX8,was shortened(all P<0.001).GPX7 and GPX8 were screened out as the key factors affecting the prognosis of LGG.The results were further used to construct a nomogram model,which suggested GPX7 was the most important variable.The concordance index of the model was 0.843(95%CI=0.809-0.853),and the calibration curve showed that the predicted and actual results had good consistency. Conclusion GPX7 is an independent risk factor affecting the prognosis of LGG,and the nomogram model constructed with it can be used to predict the survival rate of LGG.

ABSTRACT

Introduction For low-risk prostate cancer (PCa), curative treatment with radical prostatectomy (RP) can be performed, reporting a biochemical relapse-free survival rate (bRFS) at 5 and 7 years of 90.1% and 88.3%, respectively. Prostatic specific antigen (PSA), pathological stage (pT), and positive margins (R1) are significant predictors of biochemical relapse (BR). Even though pelvic lymphadenectomy is not recommended during RP, in the literature, it is performed in 34% of these patients, finding 0.37% of positive lymph nodes (N1). In this study, we aim to evaluate the 10-year bRFS in patients with low-risk PCa who underwent RP and extended pelvic lymph node dissection (ePLND). Methodology All low-risk patients who underwent RP plus bilateral ePLND at the National Cancer Institute of Colombia between 2006 and 2019 were reviewed. Biochemical relapse was defined as 2 consecutive increasing levels of PSA > 0.2 ng/mL. A descriptive analysis was performed using the STATA 15 software (Stata Corp., College Station, TX, USA), and the Kaplan-Meier curves and uni and multivariate Cox proportional hazard models were used for the survival outcome analysis. The related regression coefficients were used for the hazard ratio (HR), and, for all comparisons, a two-sided p-value ˂ 0.05 was used to define statistical significance. Results Two hundred and two patients met the study criteria. The 10-year bRFS for the general population was 82.5%, statistically related to stage pT3 (p = 0.047), higher Gleason grade group (GG) (p ≤ 0.001), and R1 (p ≤ 0.001), but not with N1. A total of 3.9% of the patients had N1; of these, 75% had R1, 25% GG2, and 37% GG3. Among the N0 (non-lymph node metástasis in prostate cáncer) patients, 31% of the patients had R1, 41% GG2, and 13% GG3. Conclusions Our bRFS was 82.5% in low-risk patients who underwent RP and ePLND. With higher pT, GG, and presence of R1, the probability of BR increased. Those with pN1 (pathologicaly confirmed positive lymph nodes) were not associated with bRFS, with a pN1 detection rate of 3.9%. Details: In low-risk PCa, curative treatment with RP can be performed, reporting a bRFS rate at 5 and 7 years of 90.1% and 88.3%, respectively. Despite the fact that pelvic lymphadenectomy is not recommended during RP in clinical guidelines, in the literature, it is performed in 34% of these patients, finding 0.37% of N1. In this study, we report the 10-year bRFS in patients with low-risk PCa who underwent surgery.


Introducción En el cáncer de próstata (CaP) de bajo riesgo se puede realizar un tratamiento curativo mediante prostatectomía radical (PR), con una tasa de supervivencia libre de recaída bioquímica (SLRb) a 5 y 7 años del 90,1% y el 88,3%, respectivamente. El antígeno prostático específico (PSA), el estadio patológico (pT) y los márgenes positivos (R1) son predictores significativos de recaída bioquímica (BR). Aunque la linfadenectomía pélvica no está recomendada durante la PR, en la literatura se realiza en el 34% de estos pacientes, encontrándose un 0,37% de ganglios linfáticos positivos (N1). En este estudio, nuestro objetivo es evaluar la SLB a 10 años en pacientes con CaP de bajo riesgo sometidos a PR y disección ganglionar pélvica extendida (DGLPe). Metodología Se revisaron todos los pacientes de bajo riesgo sometidos a PR más ePLND bilateral en el Instituto Nacional de Cancerología de Colombia entre 2006 y 2019. La recaída bioquímica se definió como 2 niveles crecientes consecutivos de PSA > 0,2 ng/mL. Se realizó un análisis descriptivo utilizando el software STATA 15 (Stata Corp., College Station, TX, USA), y se utilizaron las curvas de Kaplan-Meier y los modelos uni y multivariados de riesgos proporcionales de Cox para el análisis de resultados de supervivencia. Los coeficientes de regresión relacionados se utilizaron para la hazard ratio (HR), y, para todas las comparaciones, se utilizó un valor p de dos caras ˂ 0,05 para definir la significación estadística. Resultados Doscientos dos pacientes cumplieron los criterios del estudio. La bRFS a 10 años para la población general fue del 82,5%, estadísticamente relacionada con el estadio pT3 (p = 0,047), mayor grupo de grado Gleason (GG) (p ≤ 0,001), y R1 (p ≤ 0,001), pero no con N1. Un total del 3,9% de los pacientes tenían N1; de ellos, el 75% tenían R1, el 25% GG2, y el 37% GG3. Entre los pacientes N0 (metástasis no ganglionar en el cáncer de próstata), el 31% de los pacientes tenían R1, el 41% GG2 y el 13% GG3. Conclusiones Nuestra SSEb fue del 82,5% en los pacientes de bajo riesgo que se sometieron a RP y ePLND. A mayor pT, GG y presencia de R1, mayor probabilidad de RB. Aquellos con pN1 (ganglios linfáticos patológicamente confirmados como positivos) no se asociaron con la SSEb, con una tasa de detección de pN1 del 3,9%. Detalles: En el CaP de bajo riesgo se puede realizar tratamiento curativo con PR, reportando una tasa de SSEb a 5 y 7 años de 90,1% y 88,3%, respectivamente. A pesar de que la linfadenectomía pélvica no está recomendada durante la PR en las guías clínicas, en la literatura se realiza en el 34% de estos pacientes, encontrando un 0,37% de N1. En este estudio, reportamos la SLB a 10 años en pacientes con CaP de bajo riesgo sometidos a cirugía.

ABSTRACT

ABSTRACT Background: Periodontal disease is reportedly associated with the risk of various systemic diseases, including pancreatic and lung cancers. However, its association with prostate cancer remains inconclusive. Herein, we explored the association of periodontal disease with the risk of prostate cancer through a meta-analysis. Materials and Methods: MEDLINE, Embase, Web of Sciences and Cochrane Library databases were searched for eligible publications up to April 2020. Multivariate adjusted risk estimates with corresponding 95% confidence intervals (CIs) were extracted and calculated using random- or fixed-effect models. Results: Nine cohort studies involving 3.353 prostate cancer cases with 440.911 participants were identified and included in the meta-analysis. We found that periodontal disease significantly increased the risk of prostate cancer by 1.40-fold (hazard ratio [HR]=1.40, 95% CI: 1.16-1.70; P=0.001; I2=76.1%) compared with normal condition. Interestingly, the risk of developing prostate cancer was not significant in patients treated with periodontal therapy (HR=1.22, 95% CI: 0.86-1.73; P=0.272; I2=65.2%). The results of subgroup analyses were also consistent and significant when stratified by study design and follow-up period, whereas conflicting results were observed in periodontal disease ascertainment stratification. These findings were robust as indicated by sensitivity analyses. Conclusions: Periodontal disease was associated with the increased risk of prostate cancer, whereas no significant association was observed in patients treated with periodontal therapy. Hence, the awareness and importance for maintaining oral health should be improved, and the underlying mechanisms linking periodontal disease and prostate cancer should be fully explored in future research.

ABSTRACT

RESUMEN Introducción: en cirugía cardiovascular, el EuroSCORE I, EuroSCORE II y STS score son herramientas que brindan pronóstico e información para la toma de decisiones. Es imperativo evaluar el valor predictivo real de los mismos en nuestro medio. Objetivo: evaluar el valor predictivo de los citados scores en pacientes sometidos a cirugía cardíaca en el área de cardiología del Hospital Nacional. Metodología: estudio de cohortes, retrospectivo, con muestreo no probabilístico de casos consecutivos. La población estuvo constituida por pacientes sometidos a cirugía cardiaca en el periodo comprendido entre enero 2020 a julio 2021. Fueron evaluadas 60 historias clínicas, excluidas 6, quedando finalmente 54 expedientes. Resultado: predominó el sexo masculino 57,14 %, la edad media fue de 60 ± 12 años (rango 26 - 82 años). El EuroSCORE II presentó un riesgo relativo de 10 (IC 95 % 1,3 ­ 90), p=0,004, sensibilidad 80 %, especificidad 78,43 %, VPP 26,67 % (IC 95 % 0,95 a 52,38) y VPN 97,56 % (IC 95 % 91,62 a 100 %). El EuroSCORE I presentó riesgo relativo de 1,6 (IC 95 % 0,2 ­ 10,9) p=0,50, sensibilidad 60 %, especificidad 52,94 %, VPP 11,11 % (IC 95 % 0,00 a 24,82) y VPN 93,10 % (IC 95 % 82,16 a 100 %). El STS score arrojó un riesgo relativo de 3,5 (IC 95 % 0,07 ­ 35), p=0,10, sensibilidad del 20 %, especificidad 93,33 %, valor predictivo positivo del 25 % (IC 95 % 0,00 a 79,93) y valor predictivo negativo 91,30 % (IC 95 % 82,07 a 100 %). La mortalidad global fue 8,93 % y morbilidad 93 %. Conclusión: se demostró un alto valor predictivo negativo en los scores, lo que determinó que pacientes con riesgo bajo e intermedio tuvieran una mortalidad baja.


ABSTRACT Introduction: in cardiovascular surgery, the EuroSCORE I, EuroSCORE II and STS score are tools that provide prognosis and information for decision making. It is imperative to evaluate their real predictive value in our environment. Objective: to evaluate the predictive value of the aforementioned scores in patients undergoing cardiac surgery in the Hospital Nacional cardiology area. Methodology: retrospective cohort study, with non-probabilistic sampling of consecutive cases. The population consisted of patients undergoing cardiac surgery in the period from January 2020 to July 2021. 60 medical records were evaluated, 6 excluded, finally leaving 54 records. Result: male sex predominated 57,14 %, the mean age was 60 ± 12 years (range 26 - 82 years old). The EuroSCORE II presented a relative risk of 10 (95 % CI 1.3 - 90), p = 0.004, sensitivity 80 %, specificity 78,43 %, PPV 26,67 % (95 % CI 0,95 to 52,38) and NPV 97,56 % (95 % CI 91,62 to 100 %). The EuroSCORE I presented a relative risk of 1.6 (95 % CI 0.2 - 10.9) p = 0.50, sensitivity 60 %, specificity 52,94 %, PPV 11,11 % (95 % CI 0.00 a 24,82) and NPV 93,10 % (95 % CI 82.16 to 100 %). The STS score yielded a relative risk of 3,5 (95 % CI 0.07 - 35), p = 0.10, sensitivity of 20 %, specificity 93,33 %, positive predictive value of 25 % (CI 95 % 0 .00 to 79.93) and negative predictive value 91,30 % (95 % CI 82.07 to 100 %). Overall mortality was 8,93 % and morbidity 93 %. Conclusion: a high negative predictive value was demonstrated in the scores, which determined that patients with low and intermediate risk had a low mortality.

ABSTRACT

Resumo Fundamento O prognóstico de longo prazo pós síndrome coronária aguda (SCA) no cuidado secundário não é bem conhecido. A gravidade da doença arterial coronariana (DAC) como preditor de mortalidade no longo prazo foi avaliada em um hospital público no Brasil. Objetivo O objetivo deste estudo foi comparar o prognóstico de curto e longo prazo após um evento de SCA, de acordo com a gravidade da doença obstrutiva, em pacientes atendidos em um hospital público secundário para um coorte prospectivo sobre DAC no Brasil (o Estudo de Registro de Insuficiência Coronariana, estudo ERICO) Métodos Foram realizadas análises de sobrevida por curvas de Kaplan-Meier e modelo de risco proporcional de Cox [razão de risco (RR) com o respectivo intervalo de confiança (IC) de 95% para avaliar mortalidade cumulativa global, por DCV e DAC, de acordo com a obstrução arterial coronária: sem obstrução (grupo de referência), doença de um vaso, doença de dois vasos, doença de múltiplos vasos] entre 800 adultos do estudo ERICO durante 4 anos de monitoramento. As RR são apresentadas como dados brutos e posteriormente padronizadas quanto a possíveis fatores de confusão, no período de 180 dias até 4 anos de monitoramento após a SCA. O p-valor <0.05 foi considerado estatisticamente significativo. Resultados Taxas de sobrevida mais baixas foram detectadas entre indivíduos com a doença de múltiplos vasos (global, DCV e DAC, p de teste de Log-rank <0,0001). Depois da padronização multivariada, a doença de múltiplos vasos [RR; 2,33 (IC 95%; 1,10-4,95)] e doença de um vaso obstruído [RR; 2,44 (IC 95%; 1,11-5,34)] tiveram o risco mais alto de mortalidade global comparadas aos índices dos sujeitos sem obstrução no monitoramento de 4 anos. Conclusões Não só os pacientes com doença de múltiplos vasos como também os com doença de um vaso tiveram alto risco de mortalidade no longo prazo pós-SCA. Esses achados destacam a importância de se ter uma abordagem melhor no tratamento e no controle de fatores de risco cardiovascular, mesmo em indivíduos com risco aparentemente baixo, atendidos em cuidado secundário.


Abstract Background Long-term prognosis post-acute coronary syndrome (ACS) in secondary care is not well-known. The severity of coronary artery disease (CAD) as a predictor of long-term mortality was evaluated in a community hospital in Brazil. Objective We aimed to compare short and long-term prognosis after an ACS event according to severity of obstructive disease in patients attended in a secondary community hospital from prospective CAD cohort in Brazil (the Strategy of Registry of Acute Coronary Syndrome, ERICO study). Methods Survival analyses were performed by Kaplan-Meier curves and Cox proportional hazard models (hazard ratios (HR) with respective 95% confidence interval (CI) to evaluate cumulative all-cause, CVD and CAD mortality according the coronary artery obstruction: no-obstruction (reference group), 1-vessel-disease, 2-vessel-disease, multivessel-disease) among 800 adults from an ERICO study during a 4-year-follow-up. HR are presented as crude and further adjusted for potential confounders from 180 days to 4-year follow-up after ACS. A p-value <0.05 was considered statistically significant. Results Poorer survival rates were detected among individuals with multivessel-disease (all-cause, CVD and CAD, p-log rank< 0.0001). After multivariate adjustments, multivessel-disease -(HR; 2.33 (CI 95%; 1.10-4.95)) and 1-vessel-disease obstructed (HR; 2.44 (CI 95%; 1.11-5.34)) had the highest risk for all-cause mortality compared to those with no obstruction at 4-year follow-up. Conclusions Not only multivessel-disease, but also 1-vessel-disease patients showed a high long-term mortality risk post-ACS. These findings highlight the importance of having a better approach in the treatment and control of cardiovascular risk even in apparently low-risk individuals attended to in secondary care.

ABSTRACT

Resumen Objetivo: Los modelos de predicción de mortalidad intrahospitalaria en pacientes con falla cardiaca aguda pueden ser útiles para la toma de decisiones, situación que hace necesario evaluar la capacidad predictiva y de discriminación en la población colombiana. Método: Estudio de cohorte retrospectiva de pacientes con falla cardiaca aguda. Se evaluó el desempeño de los modelos de predicción de mortalidad intrahospitalaria ADHERE, OPTIMIZE-HF, GWTG-HF y PROTECT, durante los años 2013 a 2015. Se realizó el cálculo de la puntuación para cada uno de los modelos y se determinó la capacidad de predicción y discriminación. Resultados: Se incluyeron 776 pacientes con una edad promedio de 71.5 años (desviación estándar: 14.3), el 56% hombres, con fracción de eyección del ventrículo izquierdo del 39%. La mortalidad global fue del 6.1%. El área bajo la curva para ADHERE fue de 0.56 (intervalo de confianza del 95% [IC95%]: 0.49-0.64), para EHMRG de 0.63 (IC95%: 0.55-0.71], para GWTG-HF de 0.63 (IC95%: 0.55-0.70), para OPTIMIZE de 0.65 (IC95%: 0.56-0.74) y para PROTECT de 0.69 (IC95%: 0.60-0.77). Conclusiones: Los modelos de predicción de muerte intrahospitalaria en pacientes con falla cardiaca aguda muestran pobre desempeño y baja capacidad de predicción y discriminación en población colombiana, lo cual sugiere el desarrollo de escalas de predicción de mortalidad en pacientes con falla cardiaca aguda específicas para dicha población.


Abstract Objective: In-hospital mortality prediction models on acute heart failure can be beneficial for decision-making, a situation necessary to evaluate, our goal was to compare predictive and discriminatory capacity of Colombian population. Method: A retrospective cohort study in patients with acute heart failure was conducted. The following performance evaluation of in-hospital mortality prediction models were conducted from 2013 to 2015: ADHERE, EHMRG, OPTIMIZE-HF, GWTG-HF and PROTECT. Data was calculated for each model, prediction and discriminatory capacity was evaluated. Results: A sample of 776 patients, 56% male, with an average age of 71.5 (standard deviation: 14.3) and with left ventricle ejection fraction rate of 39% was studied. Global mortality was of 6.1%. The area under curve for ADHERE was of 0.56 (95% confidence interval [95% CI]: 0.49-0.64), for EHMRG 0.63 (95% CI: 0.55-0.71), for GWTG-HF 0.63 (95% CI: 0.55-0.70), for OPTIMIZE 0.65 (95% CI: 0.56-0.74) and for PROTECT 0.69 (95% CI: 0.60-0.77). Conclusions: The models for predicting in-hospital death in patients with acute heart failure show poor performance, predictability and discrimination in the Colombian population, suggesting the development of mortality prediction scales in patients with acute heart failure specific to our population.

ABSTRACT

The current study found that high Zeste White 10 interactor (ZWINT) expression is related to the poor prognosis of patients with a variety of cancers. This study mainly explored the relationship between the expression level of ZWINT and the prognosis of patients with lung adenocarcinoma (LUAD). Briefly, four English databases and two high-throughput sequencing databases were searched and relevant data for meta-analysis were extracted. Pooled mean difference and 95% confidence interval (CI) were used to assess the relationships between clinical features and the expression of ZWINT. Pooled hazard ratio and 95% CI were also used to assess the relationships between clinical features and the expression level of ZWINT. This meta-analysis was registered in PROSPERO (CRD42021249475). A total of 16 high-quality datasets comprising 2,847 LUAD patients were included in this study. Higher ZWINT expression levels were found in patients younger than 65 years, males, and smokers, and were correlated with advanced TNM stages and poor prognosis. Notably, there was no publication bias in this meta-analysis. Overall, our findings indicate that ZWINT is a potential biomarker for poor prognosis and clinicopathological outcomes of patients with LUAD.

ABSTRACT

O manejo clínico de pacientes com hanseníase apresenta um desafio particular que são as reações. O objetivo deste estudo de coorte não concorrente foi analisar o tempo e fatores associados à ocorrência da primeira reação durante e após o tratamento da poliquimioterapia (PQT). Avaliou-se 1.621 pacientes paucibacilares (PB = 8,9%) e multibacilares (MB = 91,1%) de 2008 a 2016 notificados no Sistema de Estados Reacionais em Hanseníase/Rondônia (SisReação/RO). Prevaleceu a ocorrência durante o tratamento da PQT = 997 (61,5%), e 624 (38,5%) somente após o PQT. A precocidade da reação, a partir do diagnóstico, foi analisada por meio de curvas de sobrevida de Kaplan-Meier e comparadas entre os grupos PB e MB, usando o teste de log-rank de Mantel-Cox; e foram construídos modelos de regressão de Cox univariada e multivariada para identificar os fatores associados à ocorrência da reação (hazard ratio) e os correspondentes IC95%. No modelo multivariado foram incluídas variáveis com valores de p < 0,2 na análise univariada. Os PB desenvolveram reação de forma mais precoce do que os MB. Outras características associaram-se à reação em menor tempo: sexo feminino e baciloscopia negativa. No período agregado (durante e após a PQT), os pacientes PB apresentaram risco 24% maior de reação do que os MB e aqueles com baciloscopia negativa aumentaram este risco em 40% comparado à baciloscopia positiva. Durante e após a PQT, os PB apresentaram 1,3 e 1,6 vezes maior risco de ocorrência da reação dos pacientes MB. Dessa forma, recomendamos priorizar ações de vigilância para reações hansênicas durante e após a PQT como medidas de prevenção de incapacidades físicas e de melhoria na qualidade de vida das pessoas acometidas pela hanseníase.


The clinical management of leprosy patients poses a specific challenge, namely lepra reactions. This non-concurrent cohort study aimed to analyze the timing of the first lepra reaction during and after polychemotherapy (PCT) and associated factors. A total of 1,621 patients were assessed (PB = 8.9% and MB = 91.1%) from 2008 to 2016, reported to the System of Reaction States in Leprosy (SisReação/RO) database. Reactions occurred predominantly during PCT (997; 61.5%) and less frequently only after PCT (624; 38.5%). Earliness of the reaction after diagnosis was analyzed with Kaplan-Meier survival curves, with comparison between the PB and MB groups using the Mantel-Cox log-rank test. Univariate and multivariate Cox regression models were constructed to identify factors associated with occurrence of lepra reactions (hazard ratio) and the corresponding 95%CI. The multivariate model included variables with p-values < 0.20 in the univariate analysis. PB patients developed reactions earlier than MB patients. Other characteristics were associated with earlier reactions: female gender and negative smear microscopy. In the aggregate period (during and after PCT), PB presented 24% higher risk of lepra reaction than MB patients, and negative smear microscopy increased this risk by 40% compared to positive smear microscopy. During and after PCT, PB presented 1.3 and 1.6 times the risk, respectively, of reactions when compared to MB patients. We thus recommend prioritizing surveillance of lepra reactions during and after PCT as measures to prevent physical disabilities and to improve quality of life for persons with leprosy.


La gestión clínica de pacientes con hanseniasis presenta un desafío particular que son las reacciones. El objetivo de este estudio de cohorte no concurrente fue analizar el tiempo y factores asociados a la ocurrencia de la primera reacción durante y tras el tratamiento de la poliquimioterapia (PQT). Se evaluó a 1621 pacientes (PB = 8,9% y MB = 91,1%) de 2008 a 2016, notificados en el Sistema de Estados Reaccionarios en Lepra (SisReação/RO). Prevaleció la ocurrencia durante la PQT = 997 (61,5%), y 624 (38,5%) solamente tras la PQT. La precocidad de la reacción a partir del diagnóstico se analizó mediante curvas de supervivencia de Kaplan-Meier y se compararon entre los grupos PB y MB, usando el test de log-rank de Mantel-Cox; asimismo, se construyeron modelos de regresión univariada y multivariada de Cox para identificar los factores asociados con la ocurrencia de la reacción (cociente de riesgos) y los correspondientes IC95%. En el modelo multivariado se incluyeron las variables con valores de p < 0,2 en el análisis univariado. Los PB desarrollaron una reacción de forma más precoz que los MB. Otras características se asociaron a la reacción en menor tiempo: sexo femenino y baciloscopia negativa. En el período agregado (durante y tras PQT), los PB presentaron un riesgo un 24% mayor de reacción que los multibacilares y la baciloscopia negativa aumentó este riesgo en un 40%, comparado con la baciloscopia positiva. Durante y tras el tratamiento PQT, los PB presentaron 1,3 y 1,6 veces el riesgo de ocurrencia de la reacción de los pacientes MB. De esa forma, recomendamos priorizar acciones de vigilancia para reacciones hansénicas durante y tras PQT, como medidas de prevención de discapacidades físicas, así como de mejoría en la calidad de vida de personas afectadas por la hanseniasis.

ABSTRACT

OBJECTIVES: Geriatric nutritional risk index (GNRI) might predict the all-cause mortality in patients with heart failure (HF). We performed a meta-analysis to evaluate the correlation between GNRI and all-cause mortality in patients with HF. METHODS: We searched the PubMed, Medline, Cochrane Library, and Embase databases for clinical trials investigating the association between GNRI and all-cause mortality in patients with HF, having the primary endpoint as all-cause mortality. RESULTS: In total, nine studies involving 7,659 subjects were included in the systematic review and meta-analysis. The results indicated that major risk and moderate risk GNRI (GNRI<92) was associated with an increased risk of all-cause mortality in elderly patients with HF (hazard ratios [HR] 1.59, 95% confidence intervals [CI] 1.37-1.85). Low risk GNRI (GNRI<98) group predicted all-cause mortality in elderly HF patients (HR 1.56, 95%CI 1.12-2.18) when compared with the high GNRI value group. A subgroup analysis indicated that the relationship between GNRI and HF might differ based on the subtype of heart failure. CONCLUSIONS: GNRI is a simple and well-established nutritional assessment tool to predict all-cause mortality in patients with HF.

ABSTRACT

INTRODUCTION@#The survival of HIV/AIDS patients on antiretroviral therapy (ART) is determined by a number of factors, including economic, demographic, behavioral, and institutional factors. Understanding the survival time and its trend is crucial to developing policies that will result in changes. The aim of this study was to compare the survival estimates of different subgroups and look into the predictors of HIV/AIDS patient survival.@*METHODS@#A retrospective cohort study of HIV/AIDS patients receiving ART at the University of Gondar teaching hospital was carried out. To compare the survival of various groups, a Kaplan-Meier survival analysis was performed. The Cox proportional hazards model was used to identify factors influencing HIV/AIDS patient survival rates.@*RESULTS@#In the current study, 5.91% of the 354 HIV/AIDS patients under ART follow-up were uncensored or died. Age (HR = 1.051) and lack of formal education (HR = 5.032) were associated with lower survival rate, whereas family size of one to two (HR = 0.167), three to four (HR = 0.120), no alcoholic consumption (HR = 0.294), no smoking and chat use (HR = 0.101), baseline weight (HR = 0.920), current weight (HR = 0.928), baseline CD4 cell count (HR = 0.990), baseline hemoglobin (HR = 0.800), and no TB diseases were associated with longer survival rate.@*CONCLUSIONS@#Fewer deaths were reported in a study area due to high patient adherence, compared to previous similar studies. Age, educational status, family size, alcohol consumption, tobacco and chat usage, baseline and current weight, baseline CD4 cell count, baseline hemoglobin, and tuberculosis (TB) diseases were all significant predictors of survival of HIV/AIDS patients.
