Objective To explore the effect of the feed-forward control on safety nursing of ophthalmologic day surgery patients under general anesthesia. Methods A total of 623 ophthalmologic day surgery patients under general anesthesia were retrospectively selected into the control group, who adapted the routine nursing in the Ophthalmic Day Surgery Center from January to December 2015; a total of 1 210 ophthalmologic day surgery patients under general anesthesia were retrospectively selected into the observation group, who received the feed-forward control of nursing safety management on the basis of routine nursing care from January to December 2016. The incidence rate of the adverse events and potential safety hazards and satisfaction rate were compared between the two groups. Results The incidence rate of the adverse events and potential safety hazards in the observation group (0.83%, 10/1 210) was lower than that in the control group (3.37%, 21/623), the satisfaction rate in the observation group (98.67%) was higher than that in the control group (97.11%), and the differences were statistically significant (P<0.05). Conclusion The application of feed-forward control in the safety care of patients during the ophthalmologic day surgery under general anesthesia can effectively reduce the incidence of adverse events and potential safety hazards, and ensure the safety of medical care.
The incidence of myopia is increasing year by year and the trend of younger age is obvious. The situation of myopia prevention and control is very serious. The sclera is the target organ for the development of myopia. When myopia occurs and develops, the ultrastructure of the sclera tissue will undergo pathological changes, resulting in a decrease in its tensile strength, then progressive axial growth and posterior sclera expansion. Scleral collagen cross-linking can effectively increase the hardness and tensile strength of scleral tissue, which may have great potential in the prevention and control of myopia, especially pathological myopia. At present, the effectiveness of scleral collagen cross-linking technology in the prevention and treatment of pathological myopia researches are still in the stage of animal experiments, and there are a lot of controversies on the safety. The development of any new technology to ensure safety is the primary condition. A comprehensive understanding of the safety of scleral collagen crosslinking in the prevention and control of myopia can provide more basis and guidance for the further study of scleral collagen crosslinking.
ObjectiveTo systematically review the efficacy and safety of Molnupiravir in the treatment of COVID-19. MethodsThe CNKI, VIP, WanFang Data, PubMed, Web of Science, Cochrane Library, and Epistemonikos COVID-19 L·OVE databases were electronically searched to collect randomized controlled trials (RCTs) related to Molnupiravir therapy for COVID-19 from inception to July, 2023. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.4 software. ResultsA total of 9 RCTs involving 32 086 patients were included. The meta-analysis results revealed that no significant differences were observed in the 28-29 day hospitalization rate, the 28-29 day mortality rate, 14-15 day PCR test conversion rate, or adverse event incidence between the two groups. However, there was a significant increase in adverse events related to four types of systemic organ diseases in the Monolaurin group. Conclusion?Current evidence shows that the safety profile of Monolaurin and its potential benefits for COVID-19 patients with a high risk of progressing to severe illness is unclear. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To evaluate the efficacy and safety of percutaneous ethanol injection for hepatocellular carcinomas of 3 cm or less. Methods Randomized controlled trials (RCTs) from the Cochrane Controlled Trials Register (Cochrane Library issue 2, 2008), PubMed (1966 to 2008), EMbase (1966 to 2008), CBMdisc (1978 to 2008), and CNKI (1979 to 2008) were electronically searched. We hand searched related published and unpublished data and their references. Randomized controlled trials of percutaneous ethanol injection to treat hepatocellular carcinomas of 3 cm or less were included. Data were extracted and evaluated by two reviewers independently using a designed extraction form. RevMan 4.2.10 software was used for data analysis. Results Seven RCTs involving 891 patients were included. We conducted subgroup analyses based on outcome measures and interventions. Compared with RFA, for treatment of hepatocellular carcinomas of 3 cm or less, PEI showed statistical differences in one and three-year survival rates and one and three-year local recurrence rates after treatment(RR=0.95, 95%CI 0.91 to 1.00; RR=0.80, 95%CI 0.71 to 0.91; RR=2.18, 95%CI 1.11 to 4.30; RR=2.59, 95%CI 1.55 to 4.32). As for hepatocellular carcinomas of 2-3 cm, PEI showed statistical difference in three year cancer free survival rates after treatment (RR=0.47, 95%CI 0.24 to 0.93) .Conclusion Considering the relatively poor quality of most included trials and small sample size, insufficient evidence was obtained in this systematic review. Therefore, more randomized controlled trials with high quality are still needed to assess and verify the efficacy and safety of this treatment.
Objectives To evaluate the effectiveness of different antidepressant drugs in addition to standard clinical care in the prevention of postnatal depression. To compare the effectiveness of different antidepressant drugs and with any other form of intervention for postnatal depression i.e. hormonal, psychological or social support. To assess any adverse effects of antidepressant drugs in either the mother or the foetus/infant.Methods The register of clinical trials maintained and updated by the Cochrane Depression, Anxiety and Neurosis Group and the Cochrane Pregnancy and Childbirth Group.Randomised studies of antidepressants alone or in combination with another treatment, compared with placebo or a psychosocial intervention in non-depressed pregnant women or women who had given birth in the previous six weeks (i.e. women at risk of postnatal depression). Data were extracted independently from the trial reports by the authors.Missing information was requested from investigators wherever possible. Data were sought to allow an intention to treat analysis.Results Two trials fullled the inclusion criteria for this review. Both looked at women with a past history of postpartum depression.Nortriptyline (n=26) did not show any benefit over placebo (n=25). Sertraline (n=14) reduced the recurrence of postnatal depression and the time to recurrence when compared with placebo (n=8). Intention to treat analyses were not carried out in either trial.Conclusions It is not possible to draw any clear conclusions about the effectiveness of antidepressants given immediately postpartum in preventing postnatal depression and, therefore, cannot be recommended for prophylaxis of postnatal depression, due to the lack of clear evidence. Larger trials are needed which also include comparisons of antidepressant drugs with other prophylactic treatments to reect clinical practice, and examine adverse effects for the foetus and infant, as well as assess womens’ attitudes to the use of antidepressants at this time.
ObjectiveTo know the status and risk factors of occupational exposure in a top-class hospital in Sichuan, and provide the basis for occupational safety and protective measures. Methods"Hospital Medical Staff Occupational Exposure Registration Form" was used in this retrospective study. Statistical analysis was performed on medical workers' exposure data between January 2011 and June 2014 in a top-class hospital in Sichuan Province. ResultsA total of 139 cases of occupational exposures were recorded in some of the medical staff. There were more females than males. Nurses had the most exposures (70.5%), and the exposure sources were mainly human immunodeficiency virus and hepatitis B virus (27.9% and 21.0%, respectively). The exposure type was mainly sharp injury (84.2%). Exposure occurred mainly in surgery (47.5%), and different job or places had different exposure types with significant differences (χ2=12.683, 20.897, P<0.05). Sharp injury was mainly caused by the scalp needle and syringe, and the injured sites were mainly upper limbs (98.3%). However, exposure to blood and body fluids occurred mainly on upper limbs (54.5%) or face (45.5%). ConclusionOccupational exposures are mainly sharp injuries, especially in surgeries. Women, nurses or medical staff with low qualifications had the highest exposure risk. Thus, occupational safety and protection training should be strengthened.
ObjectivesThe present network meta-analysis was conducted to evaluate the potential efficacy and safety of various surgical approaches in the treatment of benign prostatic hyperplasia with enlarged prostate.MethodsPubMed, EMbase, The Cochrane Library, Clinicaltrials.gov and CNKI databases were electronically searched to identify eligible studies. Two reviewers independently screened literature, extracted data and evaluated risk of bias and the ADDIS 1.16.8 software was used to conduct meta-analysis.ResultsA total of 23 studies involving 2 849 patients with 5 approaches including open prostatectomy (OP), holmium laser enucleation of the prostate (HoLEP), plasmakinetic/bipolar plasmakinetic enucleation of the prostate (PK/BPEP), transurethral vaporization of the prostate (TUVP), and laparoscopic prostatectomy (LSP) were included. HoLEP, PK/BPEP and OP were superior to the other methods in improving the objective indicators and subjective feelings of patients during both short and medium-term follow-up. However, compared with OP, HoLEP and PK/BPEP were observed to result in a significantly lower hemoglobin level (MD=1.65, 95%CI 0.35 to 4.41; MD=2.62, 95%CI 0.64 to 2.90), longer postoperative irrigation time (MD=4.67, 95%CI 1.29 to 10.66; MD=2.67, 95%CI 1.32 to 6.63), as well as indwelling catheter after operation (MD=1.64, 95%CI 0.48 to 4.15; MD=2.52, 95%CI 0.60 to 3.78). In terms of short-term complications, PK/BPEP (RR=0.45, 95%CI 0.13 to 1.29) was found to be significantly lower than that of OP.ConclusionsHoLEP and PK/BPEP can be probably used as a superior treatment option for large volume benign prostatic hyperplasia because of its better curative effect, higher safety and quick postoperative recovery.
ObjectiveTo systematically review the efficacy and safety of autologous mononuclear cells transplantation in osteonecrosis of the femoral head.MethodsPubMed, EMbase and The Cochrane Library were electronically searched to collect randomized and non-randomized controlled trials on autologous mononuclear cells transplantation for osteonecrosis of the femoral head from inception to July 31th, 2020. Two reviewers independently screened literatures, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.4 software.ResultsA total of 17 studies involving 645 hips in mononuclear cells group and 557 hips in cell-free group were included. The results of meta-analysis showed that compared with cell-free therapy, mononuclear cells therapy could improve hip function in term of Hairrs score (MD=8.11, 95%CI 4.36 to 11.87, P<0.000 1), Merle D`Aubigné Postel score (MD=2.23, 95%CI 0.97 to 3.49, P=0.000 5), WOMAC score (MD=?10.81, 95%CI ?15.80 to ?5.81, P<0.000 1), Lequesne index (MD=?2.97, 95%CI ?5.42 to ?0.52, P=0.02) and alleviate the pain (MD=?9.13, 95%CI ?12.40 to ?5.86, P<0.000 01), delay the progression of radiological staging (RR=0.55, 95%CI 0.34 to 0.89, P=0.01) and reduce the rate of total hip arthroplasty (RR=0.61, 95%CI 0.43 to 0.86, P=0.005). In terms of safety, mononuclear cell therapy did not increase the rate of complications (RR=0.77, 95%CI 0.33 to 1.83, P=0.56).ConclusionsThe current evidence shows that autologous mononuclear cells therapy is a safe and effective way for osteonecrosis of the femoral head. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
ObjectiveTo systematically review the efficacy and safety of deproteinized calf blood extractives (DCBE) for diabetic complications. MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data, CBM and VIP databases were electronically searched to collect studies on the efficacy and safety of DCBE for diabetic complications from inception to July 8th, 2020. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; then, meta-analysis was performed using RevMan 5.3 software. ResultsA total of 69 studies were included. The results of meta-analysis showed that for diabetic neuropathy, the effect rate of DCBE was superior to control, mecobalamin, vitamin B12, vitamin B1+vitamin B12, and vitamin B2, etc. For diabetic foot, the effect rate of DCBE was superior to control, sensitive antibiotic and compound salvia-miltiorrhiza injection. For diabetic retinopathy, the effect rate of DCBE was superior to control. The incidence of adverse events associated with DCBE was 4.59%. However, there was no significant difference with the control group. ConclusionCurrent evidence shows that DCBE has good efficacy and safety in diabetic neuropathy, diabetic foot, diabetic dry eye, diabetic retinopathy, and other diseases. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusion.
Objective To evaluate the efficacy and safety of different doses of intravenous immunoglobulin (IVIG) in the treatment of relapsing-remitting multiple sclerosis (RRMS). Methods We searched for randomized controlled trials of different doses of IVIG in the treatment of RRMS. We screened the retrieved studies according to the predefined inclusion and exclusion criteria, evaluated the quality of included studies, and performed meta-analyses with The Cochrane Collaboration’s Revman 4.2.0 software. Results Three randomized controlled trials of different dose of IVIG in the treatment of RRMS were included. One was of high quality and the other two were of lower quality. Heterogeneity was identified in one study which reported IVIG in postpartum RRMS. Two studies reported the relapsefree rate and no significant difference was noted between IVIG and placebo. Two studies reported the annual relapse rate, and no significant difference was observed (OR -0.00, 95% CI -0.36 to 0.36, P=0.98). Two studies reported the MRI lesions, and no difference was identified, either. The incidence of adverse events was similar between IVIG and placebo. Conclusion There is insufficient evidence to support the dose-effect relationship of IVIG in the treatment of RRMS. Therefore, an individualized dosing regimen should be applied according to patients’ tolerance and economic status.
