AIM: To investigate the prognostic significance of insulin-like growth factor-binding protein 3(IGFBP-3) in patients with ***: Prospective study that included two cohorts: outpatients with stable cirrhosis(n = 138) and patients hospitalized for acute decompensation(n = 189). Development of complications, mortality or liver transplantation was assessed by periodical phone calls and during outpatient visits. The cohort of stable cirrhosis also underwent clinical and laboratory evaluation yearly(2013 and 2014) in predefined study visits. In patients with stable cirrhosis, IGFBP-3 levels were measured at baseline(2012) and at second re-evaluation(2014). In hospitalized subjects, IGFBP-3 levels were measured in serum samples collected in the first and in the third day after admission and stored at-80 ℃. IGFBP-3 levels were measured by ***: IGFBP-3 levels were lower in hospitalized patients as compared to outpatients(0.94 mcg/mL vs 1.69 mcg/m L, P < 0.001) and increased after liver transplantation(3.81 mcg/m L vs 1.33 mcg/mL, P = 0.008). During the follow-up of the stable cohort, 17 patients died and 11 received liver transplantation. Bivariate analysis showed that death or transplant was associated with lower IGFBP-3 levels(1.44 mcg/mL vs 1.74 mcg/m L, P = 0.027). The Kaplan-Meier transplant-free survival probability was 88.6% in patients with IGFBP-3 ≥ 1.67 mcg/mL and 72.1% for those with IGFBP3 < 1.67 mcg/mL(P = 0.015). In the hospitalized cohort, 30-d mortality was 24.3% and was independently associated with creatinine, INR, SpO_2/FiO_2 ratio and IGFBP-3 levels in the logistic regression. The 90-d transplant-free survival probability was 80.4% in patients with IGFBP-3 ≥ 0.86 mcg/mL and 56.1% for those with IGFBP3 < 0.86 mcg/mL(P < 0.001). CONCLUSION: Lower IGFBP-3 levels were associated with worse outcomes in patients with cirrhosis, and might represent a promising prognostic tool that can be incorporated in clinical practice.

The association between admission electrocardiogram and 6-month change in left ventricular function and volume was assessed in 200 patients who had acute myocardial infarction that was treated with primary percutaneous coronary intervention. Logistic regression analysis indicated peak creatine phosphokinase-MB, number of Q-wave leads, QRS interval distortion, wall motion score index, and angiographic Thrombolysis In Myocardial Infarction flow grade as predictors of no functional recovery and QRS interval distortion and Thrombolysis In Myocardial Infarction flow grade as predictors of left ventricular remodeling.

作者： Wilson Takashi Hida Andre Lins de Medeiros Patrick Tzelikis Celso Takashi Nakano Antonio Francisco Pimenta Motta Pedro Carricondo Marcelo colombo Barboza Cesar Vilar Walton Nose Hospital Oftalmológico de Brasília Brasília Brasil Renato Ambrosio Eye Research Center Brasília Brasil

Background: Hard brunescent nuclei are difficult to chop with traditional techniques, because leathery tough strands may connect the posterior surface and span across the fragments, which poses a challenge to completely divide the nuclei. The ultra-chopping technique was designed to mitigate this issue. Purpose: To compare the intraoperative parameters between Ultra-Chopper and Divide & Conquer Techniques. Setting: This study was performed at Hospital Oftalmológico de Brasília, Brasília, DF, Brazil. Patients and Methods: A prospective, randomized and comparative study. Patients with the diagnosis of dense cataract and surgical extraction programmed were divided into two groups: Ultra-Chopper and Divide & Conquer. Intraoperative data were collected and submitted for the statistical analysis. Results: 36 eyes were included, 19 eyes with Ultra-Chopper and 17 eyes with Divide & Conquer. Groups were statistically equivalent in age and nucleus density. There were no surgical complications. Torsional time and cumulative dissipated energy were significantly reduced in the ultra-chopper group. The ultra-chopper group had less total case time, fluid usage and aspiration (ASP) time. Conclusion: The ultra-chopper tech- nique can reduce ultrasound energy dissipation during cataract surgery, and decrease case time, fluid usage and ASP time.

Self-rated health is a valuable outcome in geriatric rehabilitation besides objective results. The present work aims at measuring and analyzing overall health as it is perceived at admission into and at discharge from a geriatric rehabilitation ward. Overall health was self-appraised through a visual-analogue scale (VAS), spanning from 0 (worst) to 10 (best). We studied 1997 patients (70% females), aged 79 (standard deviation, s.d. 8.7) years;most were frail, either functionally, clinically and cognitively. 80% of patients were discharged to home after a length of stay lasting 47.5 (s.d. 22.7) days. At admission, 3/5 patients appraised favorably their overall health (VAS ≥ 6/10): at discharge, the proportion rose to 3/4, with a mean (s.d.) gain = 2 (2) points. The improvement in self-perceived health score positively correlates with the grade expressing clients’ overall satisfaction for the stay (p 0.001), and with discharge versus admission differences in: Barthel Index (BI) total score (p < 0.001), Tinetti total score, Mini Mental State Examination (MMSE), Geriatric Depression Scale (5?items GDS), pain (VAS 0 to 10). A Linear regression model predicting the changes in self-perceived health included changes in BI, MMSE, GDS, pain, dropping Tinetti test. Changes in self-rated health were positively correlated to functional gain adjusted for pre-morbid level, and to relative functional gain. By analysis of variance, health self-appraisal changed more favorably in patients discharged to home than for other social outcomes (all p < 0.001). As expected, trends in self-perceived health parallel improvements in objective functional gauges and subjective indicators.

1986年,Falbo等总结了自1925年以来美国及其他西方国家的200多篇关于独生子女心理发展的文献,他指出过去普遍认为在缺乏同胞的儿童教养环境下,在某些方面对儿童心理发展是不利的,认为独生子女是被娇惯坏了的,自私的,在社交能力方面存在着某种程度的异常或不适应。儿童发展现代研究的奠基者Hall曾说:“独生子女本身就是一种疾病”,显然这是对独生子女的一种偏见。近50年很多研究表明,同其他家庭结构的孩子对比,独生子女并不存在心理上或行为上的特殊缺陷。相反,在智力和学习成绩上独生子女优于大多数其他孩子。
