ABSTRACT
Coronary Artery Bypass Grafting (CABG) Surgery is considered the standard treatment for revascularization in Coronary Artery Disease. The Off-Pump Coronary Artery Bypass Graft (OPCAB) which evades the use of Cardiopulmonary Bypass (CPB) became a popular CABG procedure, due to the adverse effect of CPB. Hypothetically, OPCAB may improve the rates of perioperative Myocardial Injury, Neurocognitive Impairment, Stroke and Mortality. However, some studies showed no superior outcomes for OPCAB compared to on-pump CABG. This study aims to evaluate the short-term and long-term outcomes of OPCAB versus On-Pump CABG. The results showed that OPCAB is probably a safe procedure for patients, especially for those with high-risk conditions. OPCAB procedure showed superior short-term outcomes in terms of Myocardial Infarction, Systemic Inflammatory Response, Postoperative Cognitive Dysfunction, Renal Failure, Stroke, Pulmonary Complication, Postoperative Transfusion, Hospital stay length and infection than On-pump CABG. However, regarding long-term outcomes, Off-Pump CABG had a higher rate of incomplete revascularization and repeat revascularization and a higher risk of long-term mortality as well as lower graft patency. Furthermore, the result showed that the higher experience of the surgeons in OPCAB improves the outcome of the Surgery.
ABSTRACT
Purpose: To assess and analyze the visual outcomes of patients with retinal vein occlusions in a real?world setting with a long?term follow?up of more than 5 years. Methods: Retrospective analysis of 56 patients having retinal vein occlusions from a tertiary eye center, with a mean follow?up of 7 years was performed. Primary outcome measures were mean change in best?corrected visual acuity (BCVA) from baseline at 6 months, 1 year, 2 years, 3 years, and final visit (?5 years), proportion of patients having BCVA better than 20/40 and worse than 20/200, and mean number of injections. Secondary outcome measures were change in central macular thickness (CMT), development of subsequent retinal vein occlusion (RVO) in same eye or the other eye, and development of neovascular complications. Results: The mean change in letter score was + 11.84 in branch RVO (BRVO), +7.14 in non?ischemic central RVO (CRVO), and ?9.5 in ischemic CRVO at 1 year, which changed to + 8.57, ?5 and ? 24, respectively, at the end of follow?up. CMT had improved from 506 ± 98.8 ?m, 576.44 ± 149 ?m, and 618 ± 178.27 ?m, respectively, at baseline to 267 ± 94 ?m, 345.20 ± 122.61 ?m, and 265.50 ± 107.75 ?m, respectively, in BRVO, non?ischemic, and ischemic hemi RVO (HRVO)/CRVO groups. The total mean number of injections given in BRVO, non?ischemic CRVO, and ischemic CRVO groups were 4.6, 6.6, and 4.1, respectively. None of the patients with BRVO developed neovascular glaucoma (NVG). Non?ischemic to ischemic HRVO/CRVO conversion was noted in 4/11 eyes at a mean duration of 12.6 months. NVG was noted in 7/9 eyes (77.8%) in initial ischemic CRVO/HRVO group and 3/4 (75%) converted eyes. Conclusion: Patients with BRVO have good visual outcomes with anti?VEGF, while in CRVO results may vary considerably owing to patient compliance and treatment burden on long?term follow?up in a real?world setting
ABSTRACT
Objective:To examine the long-term survival outcomes and identify mortality risk factors for coronary artery bypass grafting patients who received venoarterial extracorporeal membrane oxygenation(VA-ECMO) for postcardiotomy cardiogenic shock.Methods:Data from 121 consecutive venoarterial extracorporeal membrane oxygenation-treated coronary artery bypass grafting(CABG) patients at Beijing Anzhen Hospital between June 2012 and December 2016 were analyzed. There were 84 males and 24 females. The median age was 62(55, 67) years, and the median body mass index was 25(23, 27)kg/m 2. Thirty-seven patients(34%) had left main artery disease, and 56 patients(52%) underwent off-pump CABG. According to the 3 year survival outcome after ECMO, patients were divided into survival group(35 cases) and non-survival group(73 cases). The differences of clinical indicators between the two groups were compared and analyzed. Multivariable Cox regression modeling was used to identify factors independently associated with 36 month mortality. Results:Sixty-five patients(60%) could be weaned from VA-ECMO, 49 patients(45%) survived to hospital discharge, and 35 patients(32%) survived to 3 years. The median( IQR) time on VA-ECMO support was 4(3, 5) days. The median( IQR) length of ICU stay and hospital stay duration were 8(5, 12) and 20(13, 29) days, respectively. Older age( HR=1.06, 95% CI: 1.03-1.10, P<0.001), left main coronary artery disease( HR=1.62, 95% CI: 1.00-2.60, P=0.048), and vasoactive inotropic score( HR=1.09, 95% CI: 1.03-1.17, P=0.007)were independent risk factors associated with 3-year mortality. The area under the receiver operating characteristic curve for the model, which was constructed with age≥60years, left main coronary artery disease, and vasoactive inotropic score>60, was 0.88(95% CI: 0.80-0.95). Conclusion:Long-term survival of patients who survive to discharge appears favorable. Older age, left main coronary artery disease, and vasoactive inotropic score were associated with 3-year mortality in coronary artery bypass grafting patients who received VA-ECMO.
ABSTRACT
Objective:To investigate the safety and long-term outcomes of fully covered self-expanding metal stent (FCSEMS) placement in patients with benign refractory pancreatic stenosis.Methods:Data of 18 patients with benign refractory pancreatic stenosis who underwent endoscopic treatment with FCSEMS in Nanjing Drum Tower Hospital between March 2013 and July 2020 were collected. The technical success, clinical success, adverse events and long-term outcomes were analyzed.Results:FCSEMS placement was successful in all 18 patients, with technical success rate of 100.0% (18/18). After stenting, the visual analogue scale (VAS) significantly decreased [2.00 (1.75, 3.00) VS 6.00 (5.00, 7.00), Z=-3.572, P<0.001]. The VAS decreased by more than 50% in 15 cases, and the clinical success rate was 83.3% (15/18). Stent-related adverse events included intolerable pain in 3 patients, stented-induced de novo stricture in 2 patients, and distal migration of stent in 2 patients. The stents were successfully removed in all patients after 137.5 (59.0, 417.0) days. There was significant reduction in terms of decreased upstream ductal dilatation after stent removal [9.1 (6.7, 14.1) mm VS 11.0 (7.6, 16.2) mm, Z=10.508, P<0.001]. After stent removal, 10 of the 14 patients maintained the response to pancreatic stenting and 4 recurred during the follow-up of 37-1 246 days. Conclusion:FCSEMS placement appears to be safe and effective in the treatment of benign refractory pancreatic stenosis and can provide persistent improvement in the stricture.
ABSTRACT
Objective To investigate the long-term effects of regular exercise during pregnancy on overweight and obese gravidas. Methods This study was based on a previous randomized controlled trial (RCT) regarding Effect of Regular Exercise Commenced in Early Pregnancy on the Incidence of Gestational Diabetes Mellitus in Overweight and Obese Pregnant Women conducted at Peking University First Hospital from December 2014 to July 2016. Totally 265 women whose prepregnant body mass index (BMI) ≥24.0 kg/m2 were enrolled in the RCT and were randomly assigned to exercise group (n=132) and control group (n=133). This study was a follow-up of all the participants at one year after delivery from March 2016 to August 2017. Body weight, body fat, fasting and 2 h glucose level in 75 g oral glucose tolerance test (OGTT), insulin resistance index and lipid profiles were compared. We also evaluated their physical activities with International Physical Activity Questionnaire (IPAQ), their dietary habits with modified Adult Dietary Behavior Assessment Scale and depression condition with Postpartum Depression Screen Scale (PDSS). Two independent samples t-test, Mann-Whitney U test and Chi-square test were used for statistical analysis. ResuLts The overall follow-up rate was 51.7% (137/265), while 64.4% (85/132) in the exercise group and 39.1% (52/133) in the control group. No significant difference in body weight loss [2.3 ( － 6.0 to 5.0) vs 1.0 ( － 1.3 to 4.7) kg], body fat percentage [(38.04±4.54)% vs (37.51±4.90) %], 2 h glucose level in 75 g OGTT [(7.30±2.80) vs (7.32±1.61) mmol/L], abnormal glucose tolerance ratio [30.0% (9/30) vs 28.8% (17/59)] or insulin resistance index (2.92±1.77 vs 2.86±1.92) was found between the control and exercise group (t or Z= － 0.940, 0.312, 3.415, 0.005, 1.743, all P>0.05). However, the fasting blood glucose in 75 g OGTT was higher in the control group [(5.53±0.92) vs (5.28±0.43) mmol/L, t=9.268, P=0.003]. The two groups showed no significant difference (exercise group vs control group) in physical activity level [219 (99-504) vs 195 (99-351)], total score of dietary habits [79.00 (72.50-87.50) vs 76.00 (70.00-82.00)] or PDSS score of depression [55.00 (41.00-77.00) vs 70.00 (46.25-84.75)] at follow-up (Z=－0.808, －1.822, －1.620, all P>0.05). Moreover, there was no significant difference in the level of serum triglyceride [(1.25±1.04) vs (1.42±0.85) mmol/L], total cholesterol [(4.56±0.71) vs (4.40±0.67) mmol/L], high density lipoprotein-cholesterol [(1.32±0.29) vs (1.22±0.21) mmol/L] or low density lipoprotein-cholesterol [(2.67±0.56) vs (2.55±0.52) mmol/L] between the exercise and control group (t=0.001, 0.020, 3.255, 0.303, all P>0.05). ConcLusions Regular exercise during pregnancy has no long-term effect on maternal health in the absence of continuing lifestyle intervention after delivery. Therefore, postpartum follow-up and continued education on healthy lifestyle should be emphasized.
ABSTRACT
Gestational diabetes mellitus(GDM) women carry a higher risk for abnormal glucose metabolism in later life and also put their offspring in a risk of abnormal glucose metabolism, overweight or obesity. Thus it is crucial to implement standard management of GDM and emphasize long-term postpartum follow-up. However, regional disparity in standard management of GDM remains in mainland China which necessitates further improvement.
ABSTRACT
Objectives: To describe the differences between patients with angiography confirmed stent thrombosis in antiplatelet therapy and long term outcomes. Methods: We analyzed data from 1 204 patients with angiography – documented stent thrombosis between January 2008 to December 2016 in Beijing Anzhen Hospital. According to the timing of stent thrombosis post stent implantation, patients were divided into acute stent thrombosis (<24 h, n=106), subacute stent thrombosis(24 h~30 d, n=206), late stent thrombosis (>30 d~1y, n=268), and very late stent thrombosis (>1 y, n=624) groups. Death, recurrent stent thrombosis, recurrent myocardial infarction, target vessel revascularization, stroke and antiplatelet treatment during In-hospital or long-term clinical follow-up were compared among groups. Results: Prevalence of stent thrombosis was the highest in the left anterior descending artery (51.9%) in acute stent thrombosis group. Subjects with subacute stent thrombosis had a higher prevalence rate of LVEF<50% (28.2%), and subjects with very late stent thrombosis had a higher prevalence rate of diabetes (34.1%). All patients in acute stent thrombosis group received aspirin + clopidogrel, 96.5% patients in subacute stent thrombosis group and 94.5% patients in late stent thrombosis group were treated with double or triple antiplatelet therapy, while 95.2% patients in the very late stent thrombosis group were treated with double or mono antiplatelet therapy. During the follow up, mortality was 23.6%, 26.7%, 26.3% and 18.9% in acute stent thrombosis, subacute stent thrombosis, late stent thrombosis, and very late stent thrombosis groups, respectively. Conclusions: Most patients with angiography–documented stent thrombosis are treated with recommended antiplatelet therapy. Development of stent thrombosis is associated with poor outcomes.
ABSTRACT
As a progressive chronic disease,age-related macular degeneration (AMD) is the leading cause of blindness worldwide.However,current therapy for AM D shows a dramatic breakthrough.More and more patients with AMD undergo intravitreous injection of anti-vascular endothelial growth factor A (VEGF-A) regimen,which has been demonstrated a beneficial therapeutic treatment to improve visual acuity in a short period.The long-term outcomes have come into focus considering prolonged treatment cycle and follow-up period.The long-term outcomes and safety of anti VEGF-A will be reviewed in this article contributing to investigate the causes influencing prognosis of visual acuity after anti VEGF-A treatment.
ABSTRACT
Endoscopic submucosal dissection (ESD) is becoming the main procedure for the resection of early gastric cancer (EGC). The absolute indications for treating EGC with endoscopic resection were established by the Japanese Gastric Cancer Association and have been generally accepted. However, the absolute indications for treating EGC are rather strict, and expanded indications have been developed. Many studies have reported favorable long-term outcomes for patients who received curative resection for the expanded indication. ESD preserves the stomach, thereby improving patients’ quality of life compared to surgery; however, a generally higher incidence of metachronous gastric cancer has been reported after ESD for EGC. Therefore, clinicians must pay careful attention during surveillance endoscopy, even after a curative ESD.

ABSTRACT
Objective To study the long-term results of using an autologous vascularized pedicled flap of gastric tissues in the repair of traumatic bile duct strictures.Methods From 2002 to 2016,38 patients with traumatic bile duct strictures underwent repair using an autologous vascularized pedicled flap of stomach tissues.The postoperative morbidity,mortality,long-term clinical results,liver function and the rate of biliary stricture recurrence were studied.Results The overall complication rate was 18.4％ (7/38).A delay in healing of the incision wound occurred in 4 patients,biliary fistula in 2,and ascites in 1.Two patients died of malignant tumor.The median follow-up was 92 (61 ～ 107) months and the follow-up rate was 100％.Excellent results were obtained in 97.2％ (35/36) of patients.Abnormal liver function was detected in 1 patient which improved with treatment using choleretic drugs.The remaining 35 patients had normal liver functions with absence of abdominal pain.Conclusions To repair traumatic bile duct strictures using an autologous vascularized pedicled flap of stomach tissues was safe and reliable,and good long-term outcomes are available.
ABSTRACT
@#Objective To evaluate long-term outcomes of surgical closure of atrial septal defect (ASD) and combined surgical radiofrequency ablation for atrial fibrillation (AF). Methods A total of consecutive 15 patients with ASD undergoing surgical closure of ASD and combined surgical radiofrequency ablation in our department between March 2003 and April 2015. There were 7 males and 8 females at an average age of 47.1±10.8 years ranging from 16 to 62 years. Retrospective analysis and follow-up were performed to evaluate long-term success rate freedom from AF after surgery. Results All patients recovered and discharged, and no patient suffered death or stroke. The duration of follow-up was from 3 to 136 months for all patients. Success rate freedom from AF at 1, 3, 5 and 10 years was 81.3%, 75.0%, 68.8% and 61.1%, respectively. During follow-up, there was no death or stroke. One patient required permanent pacemaker implantation. Conclusion Concomitant surgical closure of ASD and biatrial radiofrequency ablation is safe and effetive with better long-term outcomes. It is necessary to perform the two procedures together for ASD patients.
ABSTRACT
BACKGROUND: In recent years, introduction of novel immunosuppressive agents and its proper implementation for clinical practice have contributed to improving clinical outcomes of kidney transplantation (KT). Here, we report clinical outcomes of KTs and related risk factors. METHODS: From July 1998 to June 2016, 354 KTs (182 from living and 172 from deceased donors) have been performed at Ulsan University Hospital. We retrospectively reviewed the clinical characteristics and outcomes of KT recipients, then estimated graft and patient survival rate were estimated and analyzed risk factors using Cox-regression. RESULTS: The median follow-up period was 53 months (range; 3 to 220 months). The mean ages of recipients and donors were 45.0 years (SD, 12.5) and 44.7 years (SD, 13.6) years, respectively. During follow-up, 18 grafts were lost and 5- and 10-year death-censored graft survival was 96.7% and 91.5%, respectively. Biopsy-proven acute rejection (BPAR) occurred in 71 patients (55 cases of acute cellular rejection and 16 of antibody-mediated rejection). Cox-regression analysis showed that BPAR was a risk factor related to graft loss (hazard ratio [HR], 14.38; 95% confidence interval [CI], 3.79 to 54.53; P < 0.001). In addition, 15 patients died, and the 5- and 10-year patient survival was 97.2% and 91.9%, respectively. Age ≥60 years (HR, 6.03; 95% CI, 1.12 to 32.61; P=0.037) and diabetes (HR, 6.18; 95% CI, 1.35 to 28.22; P=0.019) were significantly related to patient survival. CONCLUSIONS: We experienced excellent clinical outcomes of KT in terms of graft failure and patient survival despite the relatively high proportion of deceased donors. Long-term and short-term clinical outcomes have improved in the last two decades.

Objective To explore the long-term outcomes of endoscopic submucosal dissection (ESD) of gastric GISTs.Methods Data of 25 patients with gastric stromal tumors,who underwent ESD,were reviewed in terms of clinical characteristics,histopathologic results,complications and long-term outcomes.Results Twenty-five patients underwent one-time complete removal of lesion, with a average tumor size of 3.0 cm (range,0.6 to 7.6 cm).The average time of operation was 65 minutes (range,15 to 154 minutes).one case was observed with intraoperative hemor-rhage of 200 mL blood,which was successfully managed by hemostatic forceps.Perforation with incidence rate of 16%occurred in 4 cases and was closed well with clips.Mucosal mechanical laceration of esophagus occurred in 1 case when the big tumor was taken out.The average length of hospi-talization was 7.3 days (range,4 to 21 days).A follow-up for 30 months (range,13 to 54 months) showed no tumor recurrence or metastasis. Conclusion ESD is an effective and safe endoscopic procedure to remove gastric GISTs for long-term outcomes in patients with no metastasis.
ABSTRACT
Objective To investigate the clinical efficacy of laparoscopy-assisted radical gastrectomy for gastric cancer.Methods The retrospective cohort study was adopted.The clinical data of 210 patients with gastric cancer who underwent laparoscopy-assisted radical gastrectomy at the Peking University Cancer Hospital between May 2009 and December 2012 were collected.Fifty-two,43 and 115 patients were respectively detected in stage Ⅰ,Ⅱ and Ⅲ of postoperative pathological stage.Laparoscopy-assisted radical distal,proximal and total gastrectomies were selectively performed according to the location and extent of tumors.(1) Overall treatment indicators were observed,including surgical procedure,with or without conversion to open surgery,operation time,volumes of intraoperative blood loss and transfusion,number of lymph node dissected,time to anal exsufflation,duration of hospital stay,occurrence of complications,radical degree of tumors of pathological examination.(2) Other indicators were observed,including pathological features of patients in stage Ⅰ,Ⅱ and Ⅲ [gender,age,body mass index (BMI),scores of American Society of Anesthesiologists (ASA),medicinal complication,location of tumors,degree of tumor differentiation and with or without vascular tumor thrombi],intraoperative and postoperative situations (surgical procedure,conversion to open surgery,operation time,volumes of intraoperative blood loss and transfusion,number of lymph node dissected,time to anal exsufflation,duration of hospital stay and radical degree of tumors),postoperative complications,reoperation,death within postoperative day 30 and during follow-up,3-and 5-year survival rates.(3) Evaluation criteria:stages and classification of tumors were evaluated according to the tumor node metastasis (TNM) classification of malignant tumours (Seventh Edition) published by American Joint Committee on Cancer (AJCC) and Union for International Cancer Control (UICC).Severity of complications was evaluated according to Clavien-Dindo classification.Patients were followed up by outpatient examination,telephone interview and correspondence once every half a year up to December 31,2015,abdominal / pelvic CT,chest X-ray and blood test were performed once every half a year within 2 years and once every year within 2-5 years postoperatively,and gastroscopy was performed once every year.Overall survival time was counted from operation date to end of follow-up or time of death.Measurement data with normal distribution were presented as x ± s and comparison between groups was analyzed using the ANOVA.Measurement data with skewed distribution were presented as M (range) and comparison between groups was analyzed using nonparametric test.Comparisons of count data were analyzed using the chisquare test.Survival curve was drawn by the Kaplan-Meier method,and survival analysis was done using the Logrank test.Results (1) Overall treatment:all the 210 patients underwent successful radical gastrectomy,including 100 undergoing distal gastrectomy,35 undergoing proximal gastrectomy and 75 undergoing total gastrectomy.There were 198 patients undergoing radical gastrectomy and 12 patients converted to open surgery.Operation time,volume of intraoperative blood loss,number of patients with blood transfusion and number of lymph node dissected were (258 ± 54) minutes,(103 ± 86) mL,19 and 29 ± 12,respectively.Postoperative recovery:time to anal exsufflation and duration of hospital stay were (3.8 ± 0.9) days and (17 ± 7) days.Fortyfive patients had postoperative complications and 2 were dead within 30 days postoperatively.R0 and R1 resections were respectively applied to 209 and 1 patients.(2) Comparisons among the patients with the different pathological stage:numbers of patients in stage Ⅰ,Ⅱ and Ⅲ were 9,17 and 36 with tumor located in the upper stomach,3,9 and 22 with tumor located in the middle stomach,40,16 and 47 with tumor located in the lower stomach,0,1 and 10 with tumor located in the cross-region stomach,30,23 and 23 in G1 and G2 of tumor differentiation,21,19 and 92 in G3 and G4 of tumor differentiation,7,13 and 69 with vascular tumor thrombi,respectively,with significant differences in above indicators among the patients in stage Ⅰ,Ⅱ and Ⅲ (x2 =25.990,32.928,35.027,P ＜ 0.05).(3) Intra-and post-operative comparisons among the patients with the different pathological stage:numbers of patients in stage Ⅰ,Ⅱ and Ⅲl were respectively 40,20 and 40 with distal gastrectomy,3,8 and 24 with proximal gastrectomy,9,15 and 51 with total gastrectomy,and number of lymph node dissected were 26 ± 9,29 ± 13 and 31 ± 12 in patients with stage Ⅰ,Ⅱ and Ⅲ,showing significant differences in above indicators among the patients in stage Ⅰ,Ⅱ and Ⅲ (x2 =25.730,F =4.336,P ＜ 0.05).(4) Numbers of patients with postoperative overall complications were 11,8 and 26 in stage Ⅰ,Ⅱ and Ⅲ,showing no significant difference (x2 =0.301,P ＞ 0.05).(5) Of 210 patients,203 were followed up for a median time of 43 months (range,1-80 months) with a follow-up rate of 96.67％ (203/210).Sixty-eight patients were dead till the end of follow-up,including 60 died of recurrence of tumor,2 died of surgical complications and 6 died of other causes.Postoperative 3-,5-year overall survival rates were 96.1％,87.8％,62.4％ and 92.9％,77.5％,52.7％ in patients with stage Ⅰ,Ⅱ and Ⅲ,respectively,with a significant difference (x2 =29.071,P ＜ 0.05).Conclusion Laparoscopy-assisted radical gastrectomy for advanced gastric cancer is at least equivalent to early gastric cancer in the safety,with the satisfactory long-term outcomes.
ABSTRACT
OBJECTIVE: The purpose of this study was to evaluate long-term follow-up radiologic/clinical outcomes of patients who underwent anterior cervical discectomy and inter-body fusion (ACDF) with stand-alone cages (SAC) in a single academic institution. METHODS: Total 99 patients who underwent ACDF with SAC between February 2004 and December 2012 were evaluated retrospectively. A total of 131 segments were enrolled in this study. Basic demographic information, radiographic [segmental subsidence rate, fusion rate, C2-7 global angle, and segmental angle changes)/clinical outcomes (by Odom's criteria and visual analog score (VAS)] and complications were evaluated to determine the long-term outcomes. RESULTS: The majority were males (55 vs. 44) with average age of 53.2. Mean follow-up period was 62.9 months. The segmental subsidence rate was 53.4% and fusion rate was 73.3%. In the subsidence group, anterior intervertebral height (AIH) had more tendency of subsiding than middle or posterior intervertebral height (p=0.01). The segmental angle led kyphotic change related to the subsidence of the AIH. Adjacent segmental disease was occurred in 18 (18.2%) patients. Total 6 (6%) reoperations were performed at the index level. There was no statistical significance between clinical and radiological outcomes. But, overall long-term clinical outcome by Odom's criteria was unsatisfactory (64.64%). The neck and arm VAS score were increased by over time. CONCLUSION: Long-term outcomes of ACDF with SAC group were acceptable but not satisfactory. For optimal decision making, more additional comparative long-term outcome data is needed between ACDF with SAC and ACDF with plating.

Background: Long-term outcomes of drug-eluting stents (DES) versus bare-metal stents (BMS) in patients with ST-segment elevation myocardial infarction (STEMI) remain uncertain. Objective: To investigate long-term outcomes of drug-eluting stents (DES) versus bare-metal stents (BMS) in patients with ST-segment elevation myocardial infarction (STEMI). Methods: We performed search of MEDLINE, EMBASE, the Cochrane library, and ISI Web of Science (until February 2013) for randomized trials comparing more than 12-month efficacy or safety of DES with BMS in patients with STEMI. Pooled estimate was presented with risk ratio (RR) and its 95% confidence interval (CI) using random-effects model. Results: Ten trials with 7,592 participants with STEMI were included. The overall results showed that there was no significant difference in the incidence of all-cause death and definite/probable stent thrombosis between DES and BMS at long-term follow-up. Patients receiving DES implantation appeared to have a lower 1-year incidence of recurrent myocardial infarction than those receiving BMS (RR = 0.75, 95% CI 0.56 to 1.00, p= 0.05). Moreover, the risk of target vessel revascularization (TVR) after receiving DES was consistently lowered during long-term observation (all p< 0.01). In subgroup analysis, the use of everolimus-eluting stents (EES) was associated with reduced risk of stent thrombosis in STEMI patients (RR = 0.37, p=0.02). Conclusions: DES did not increase the risk of stent thrombosis in patients with STEMI compared with BMS. Moreover, the use of DES did lower long-term risk of repeat revascularization and might decrease the occurrence of reinfarction. .
Fundamento: Os resultados a longo prazo dos stents farmacológicos (SF) contra stents convencionais (SC) em pacientes com infarto do miocárdio com elevação do segmento ST (IMEST) permanecem incertos. Objetivo: Investigar os resultados a longo prazo dos stents farmacológicos (SF) contra stents convencionais (SC) em pacientes com infarto do miocárdio com elevação do segmento ST (IMEST) . Métodos: Foi realizada pesquisa de dados nas bases de dados MEDLINE, EMBASE, na Cochrane Library, e na ISI Web of Science (até fevereiro de 2013) para estudos clínicos aleatórios que comparam a eficácia durante mais de 12 meses ou a segurança do SF com SC em pacientes com IMEST. Foi apresentada uma estimativa agrupada com risco relativo (RR) e seu intervalo de confiança de 95 % (IC), utilizando modelo de efeitos aleatórios. Resultados: Dez estudos com 7.592 participantes com IMEST foram incluídos. Os resultados gerais mostraram que não houve diferença significativa na incidência de morte por todas as causas e trombose de stent definida/provável entre SF e SC em seguimento de longo prazo. Os pacientes que receberam implante de SF pareciam ter uma incidência de infarto do miocárdio recorrente inferior a1 ano que aqueles que receberam SC (RR = 0,75, 95% CI 0,56-1,00, p = 0,05). Além disso, o risco de revascularização do vaso alvo (RVA) depois de receber o SF diminui consistentemente durante a observação a longo prazo (todos p <0,01). Na análise de subgrupo, o uso de stents com eluição de everolimus (EEE) foi associado a um risco reduzido de trombose de stent em pacientes IMEST (RR = 0,37, p = 0,02). Conclusões: SF não aumentou o risco de trombose de stent em pacientes com IMEST em comparação com SC. Além disso, o uso de SF fez baixar o risco de longo prazo de repetição ...

Limited data are available on the long-term clinical efficacy of drug-eluting stent (DES) in diffuse long lesions. From May 2006 to May 2007, a total of 335 consecutive patients (374 lesions) were underwent percutaneous coronary intervention with implantation of long DES (> or = 30 mm) in real world practice. Eight-month angiographic outcomes and 2-yr clinical outcomes were compared between SES (n = 218) and PES (n = 117). Study endpoints were major adverse cardiac events including cardiac death, myocardial infarction, target-lesion revascularization, target-vessel revascularization and stent thrombosis. Baseline characteristics were similar in the two groups as were mean stent length (44.9 +/- 15.2 mm in SES and 47.4 +/- 15.9 in PES, P = 0.121). Late loss at 8 months follow-up was significantly lower in SES than in PES group (0.4 +/- 0.6 mm in SES vs 0.7 +/- 0.8 mm in PES, P = 0.007). Mean follow-up duration was 849 +/- 256 days, and 2-yr cumulative major adverse cardiac events were significantly lower in the SES than in the PES group (5.5% in SES vs 15.4% in PES, P = 0.003). In conclusion, long-term DES use in diffuse long coronary lesions is associated with favorable results, with SES being more effective and safer than PES in this real-world clinical experience.

OBJECTIVE: The aim of our study was to evaluate the effects of low doses of clozapine in flexible regime in comparison with haloperidol and chlorpromazine in long term. METHOD: The naturalistic study was prospective, active-controlled with 325 adult outpatients of both genders (140 females), with mean year age of 34.8 (range 21-57), suffering from chronic schizophrenia. The first onset of illness was at the mean of 27.9 years (range 17-38), and subjects had the mean year age of 4.1±0.5 previous relapses. The patients were allocated to receive haloperidol (105 subjects, dose range 2-15 mg), chlorpromazine (n=105, 100-400 mg) or clozapine (n=115, 75-600 mg). The scores of psychometric instruments (GWB, PANSS, CGI) were regularly assessed during 5 year period. RESULTS: The sixty-six responders were included in per-protocol analysis: 12, 10 and 16 with positive and 7, 6 and 15 with negative schizophrenic syndrome in haloperidol, chlorpromazine and clozapine group, respectively. The statistically significant differences in all psychometric scores was found, for both schizophrenic syndromes, favoring clozapine. The distribution of eighteen different types of adverse events, which we noted, were significantly different among treatment groups ( ÷2=315.7, df=34, p<0.001). Clozapine was safer and had fewer adverse effects (average of 0.9 adverse events per patient) than haloperidol (2.7) and chlorpromazine (3.2). CONCLUSIONS: Clozapine, in low doses of flexible regime, in long term (five years) showed better effectiveness in chronic schizophrenics with positive and negative symptoms than typical antipsychotics.
OBJETIVO: O propósito deste estudo foi avaliar os efeitos de baixas doses de clozapina em regime flexível comparando com o uso de haloperidol e clorpromazina por período de 5 anos. MÉTODO: Um estudo prospectivo naturalístico, ativo-controlado foi realizado com 325 pacientes com idade média de 34,8 (variância 21-57). Todos com diagnóstico de esquizofrenia. No primeiro surto da doença os pacientes apresentavam idade média de 27,9 anos (variância 17-38) e os surtos subsequentes apareceram em média 4,1±0,5 anos após. Os pacientes foram orientados a receberem haloperidol (105 pacientes com dose entre 2 e 15 mg), clorpromazina (105 pacientes com dose entre 100 e 400 mg) e clozapina (115 pacientes com dose entre 75 e 600 mg). Os instrumentos psicométricos utilizados (GWB, PANSS e CGI) foram regularmente empregados durante os 5 anos do estudo. RESULTADOS: Os 66 pacientes respondedores ao tratamento foram incluídos no protocolo de análise: 12, 10 e 16 apresentavam síndrome esquizofrênica positiva e 7, 6 e 15 síndrome negativa esquizofrênica com haloperidol, clorpromazina e clozapina, respectivamente. Diferenças estatísticas significantes foram observadas em todas as avaliações psicométricas em ambas síndromes esquizofrênicas favorecendo a clozapina. A distribuição de 18 tipos de efeitos colaterais observados foi diferente de modo significativo entre os 3 grupos estudados. A clozapina foi a droga que apresentou menos efeitos colaterais. CONCLUSÃO: A clozapina administrada por longo termo em pequenas doses em regime flexível apresenta melhor eficácia nas síndromes esquizofrênicas quando comparada a outras drogas antipsicóticas.
