ABSTRACT
Objective: To gather current evidence on the impact of antipsychotics on long-term mortality in patients with schizophrenia. Methods: We systematically searched for articles in Embase, PubMed, and PsycINFO reporting the long-term mortality (follow-up > 1 year) of patients with schizophrenia who were using any antipsychotics. We then conducted multiple meta-analyses to determine differences in long-term mortality between different types of antipsychotics. Results: We identified 45 articles that provided unadjusted long-term mortality rates, including 46,171 deaths during 2,394,911 person-years. The pooled mortality rate was 9.9 (95%CI = 7.4-12.7) per 1,000 person-years. The unadjusted crude mortality rate of antipsychotic drug users was lower than that of non-users (risk ratio [RR] = 0.546, 95%CI = 0.480-0.621), first-generation antipsychotics caused higher all-cause mortality than second-generation antipsychotics (RR = 1.485, 95%CI = 1.361-1.620), and polypharmacy had better effects than monotherapy on long-term mortality (RR = 0.796, 95%CI = 0.689-0.921). As for the causes of death, heart disease and cardiovascular disease ranked highest among cause-specific mortality (5.6 per 1,000 person-years). Conclusion: Since antipsychotics had a beneficial effect on long-term mortality in schizophrenia, greater precaution should be taken with patients who do not take them. However, since disease severity, comorbidities, and other confounding factors cannot be fully controlled, further research and verification are needed.
ABSTRACT
Objective To investigate the effect of 1.94 μm thulium laser enucleation of benign prostatic hyperplasia (BPH) with volume >80 ml by morcellator. Methods From September 2014 to June 2016, there were 95 BPH patients with prostate volume over 80 ml treated by thulium laser were divided into two groups according to the surgical procedure: 45 cases in group A, prostate tissue were washed out of bladder after vapoenucleation by 1.94 μm thulium laser; 50 cases in group B, the enucleated prostate tissue were extracted by morcellator. The operation time, the decreasing level of hemoglobin on the first day after surgery, the hospitalization time, the gland tissue weight, catheterization duration, short-term incidence of complications, and the IPSS, PVP, Qmax, QOL in 3 months after surgeon of the two groups were observed and recorded. Results There was significant difference in operation time and gland tissue weight between the two groups. The group B have significantly short operation time compared with group A (P < 0.05), and obtained gland tissue remarkably exceed the group A (P < 0.05). No significant difference was found in hemoglobin level, hospitalization time, catheterization duration, and short-term complication between the two groups (P > 0.05). The IPSS, PVR, Qmax and QOL of 3 month, after operation were significantly improved but without any significant difference between the two groups (P < 0.05). Conclusion Vaporization cutting tissue or morcellating tissue after 1.94 μm thulium laser enucleation has high safety, good curative effect and low complication, while extraction prostate tissue by morcellator can shorten the operation time and get more tissues.
