RESUMEN
<p><b>BACKGROUND</b>Weight gain following smoking cessation increases cardiovascular risk, but its effects on prognosis after percutaneous coronary intervention (PCI) remain unclear. This study aimed to investigate the relationship between weight gain post smoking cessation and one-year clinical outcome in patients who underwent PCI with drug-eluting stent (DES).</p><p><b>METHODS</b>A total of 895 consecutive male smoking patients were divided into quitters (n = 437) and continuers (n = 458) according to their smoking status after PCI. Weight gain, major adverse cardiac events (MACE, including cardiac deaths, myocardial infarction and revascularization), and recurrent angina were recorded during follow-up for one year.</p><p><b>RESULTS</b>Average weight gain in quitters was more than that in continuers (1.5 kg vs. -0.03 kg, P < 0.001). Weight was unchanged or increased by more than 1.5 kg in 78.17% of continuers, while 50.57% of quitters had a weight gain of less than 1.5 kg. Compared with continuers, MACE in quitters was significantly reduced after PCI (6.12% vs. 4.81%, P = 0.049), especially recurrent angina (13.97% in continuers vs. 9.84% in quitters, P = 0.027). After adjusting for weight gain and other factors, smoking cessation was independently associated with a lower risk of MACE and recurrent angina (OR = 0.73, P = 0.035). However, weight gain > 1.5 kg (OR = 1.55, P = 0.026) could curtail the benefits from smoking cessation.</p><p><b>CONCLUSIONS</b>Weight gain may reduce the benefits of smoking cessation after PCI with DES implantation. Thus, although smoking cessation is recommended after PCI, weight control should also be highly encouraged for these patients.</p>

<p><b>BACKGROUND</b>Insulin resistance (IR) is significantly associated with coronary artery disease and cardiovascular events in patients with or without type 2 diabetes mellitus. This study aimed to evaluate the influence of IR on long-term outcomes of patients undergoing percutaneous coronary intervention (PCI) with sirolimus-eluting stent (SES) implantation.</p><p><b>METHODS</b>A total of 467 consecutive patients undergoing SES-based PCI were divided into IR group (n = 104) and non-IR group (n = 363). The patients were followed up for one year. The rate of major adverse cardiac events (MACEs) including death, non-fatal myocardial infarction and recurrent angina pectoris was compared by the log-rank test, and the independent risk factors were identified by the Cox regression analysis.</p><p><b>RESULTS</b>MACEs occurred more frequently, and cumulative survival rate was lower in the IR group than in the non-IR group during the follow-up (all P < 0.05). IR was an independent risk factor for the occurrence of cardiac death and non-fatal myocardial infarction (OR = 2.76, 95%CI = 1.35 - 5.47, P = 0.034). Old age, diabetes, and multi-vessel disease were determinants for recurrent angina pectoris after PCI (P < 0.05). Subgroup analysis revealed that IR (OR = 3.35, 95%CI = 1.07 - 13.59, P = 0.013) and multi-vessel disease (OR = 2.19, 95%CI = 1.01 - 5.14, P = 0.044) were independent risk predictors for recurrent angina pectoris in patients with diabetes after PCI.</p><p><b>CONCLUSIONS</b>IR is associated with reduced MACE-free survival and remains an independent predictor for recurrent angina pectoris after PCI with SES implantation.</p>

<p><b>BACKGROUND</b>Non-penetrating trabecular surgery is a new filtrating surgery without opening in ternal trabecular structures. This study was to estimate the overall efficacy of non-penetrating trabecular surgery for open angle glaucoma.</p><p><b>METHODS</b>The published articles selected for this study were obtained by a computerised Medline and China Biological Medicine Disk search of the literature and a manual search of the bibliographies of relevant articles. Articles meeting the inclusion criteria were reviewed systematically, and the reported data were aggregated using the statistical techniques of meta-analysis.</p><p><b>RESULTS</b>A total of 37 articles were included in the meta-analysis. The pooled complete success rates of non-penetrating trabecular surgery with different techniques were: deep sclerectomy single, 69.7% (95% CI: 58.5% - 81.0%); deep sclerectomy with collagen implant, 59.4% (95% CI: 47.0% - 71.8%); deep sclerectomy with reticulated hyaluronic acid implant, 71.1% (95% CI: 56.8% - 85.3%); and viscocanalostomy, 72.0% (95% CI: 57.6% - 86.4%). The overall weighted complete success rate of non-penetrating trabecular surgery was 67.8% (95% CI: 61.4% - 74.3%).</p><p><b>CONCLUSIONS</b>Non-penetrating trabecular surgery is the best available therapy method for medically uncontrolled open angle glaucoma with a complete success rate of over 60%. But the different techniques cannot belie the complete success rate of non-penetrating trabecular surgery.</p>
