RESUMO
PURPOSE@#To evaluate the outcomes with and without aid of a computer-assisted surgical navigation system (CASNS) for treatment of unilateral orbital wall fracture (OWF).@*METHODS@#Patients who came to our hospital for repairing unilateral traumatic OWF from 2014 to 2017 were included in this study. The patients were divided into the navigation group who accepted orbital wall reconstruction aided by CASNS and the conventional group. We evaluated the surgical precision in the navigation group by analyzing the difference between actual postoperative computed tomography data and preoperative virtual surgical plan through color order ratios. We also compared the duration of surgery, enophthalmos correction, restoration of orbital volumes, and improvement of clinical symptoms in both groups systemically. Quantitative data were presented as mean ± SD. Significance was determined by the two-sample t-test using SPSS Version 19.0 A p < 0.05 was considered statistically significant.@*RESULTS@#Seventy patients with unilateral OWF were included in the study cohort. The mean difference between preoperative virtual planning and actual reconstruction outcome was (0.869 ± 0.472) mm, which means the reconstruction result could match the navigation planning accurately. The mean duration of surgery in the navigation group was shorter than it is in the control group, but not significantly. Discrepancies between the reconstructed and unaffected orbital-cavity volume and eyeball projection in the navigation group were significantly less than that in the conventional group. One patient had remnant diplopia and two patients had enophthalmos after surgery in the navigation group; two patients had postoperative diplopia and four patients had postoperative enophthalmos in the conventional group.@*CONCLUSION@#Compare with the conventional treatment for OWF, the use of CASNS can provide a significantly better surgical precision, greater improvements in orbital-cavity volume and eyeball projection, and better clinical results, without increasing the duration of surgery.
RESUMO
Objective To understand the status of hand hygiene(HH)of health care workers(HCWs)in a tertiary hospital in Zhuhai.Methods HH compliance of doctors,nurses,and cleaners randomly selected from 15 clinical de-partments in the whole hospital was observed through concealed observation by medical interns in October-Novem-ber 2016.Results HH compliance rate and correct rate of clinical departments in the whole hospital were 33.44%(1 131/3 382)and 59.86%(677/1 131)respectively,there was a significant difference in the compliance rate of HH among different types of HCWs (χ2 ＝12.610,P＝0.002),HH compliance rate from high to low was nurses (35.85%),cleaners (32.28%),and doctors (29.50%).Of five HH moments,HCWs’HH compliance rate after patient’s body fluid exposure was the highest (69.74%),while after touching patient surroundings was the worst (25.03%).HH compliance rates of HCWs with different occupations at different HH moments were all significant-ly different (all P＜0.05),HH compliance rates of doctors before aseptic procedure and after patient’s body fluid exposure were higher than nurses(71.25% vs 32.44%;82.86% vs 69.78%,respectively),HH compliance rate of nurses was highest after touching a patient(40.06%).Conclusion HH status in this hospital is not optimistic,HH compliance rate and correct rate are low,HH compliance rates of HCWs with different occupations and at different HH moments are both different,which need to be improved.
RESUMO
<p><b>Background:</b>Studies on the association between spicy food intake and cancer risk have reported inconsistent results. We quantitatively assessed this association by conducting a meta-analysis based on evidence from case-control studies.</p><p><b>Methods:</b>PubMed, EMBASE, and the Cochrane Library were searched for eligible publications. Combined odds ratios (OR s) with their 95% confidence interval (CI) were calculated using a random- or fixed-effects model. The methodological quality of the included articles was assessed using the Newcastle-Ottawa scale (NOS). All data were analyzed using STATA 11.0 software (version 11.0; StataCorp., College Station, TX, USA). Subgroup analyses were also performed with stratification by region, sex, number of cases, cancer subtype, source of the control group, and NOS score.</p><p><b>Results:</b>A total 39 studies from 28 articles fulfilled the inclusion criteria for the meta-analysis (7884 patients with cancer and 10,142 controls). Comparison of the highest versus lowest exposure category in each study revealed a significant OR of 1.76 (95% CI = 1.35-2.29) in spite of significant heterogeneity (P < 0.001). In the subgroup analyses, this positive correlation was still found for gastric cancer, different regions, different numbers of cases, different sources of the control group, and high-quality articles (NOS score of ≥ 7). However, no statistically significant association was observed for women, esophageal cancer, gallbladder cancer, or low-quality articles (NOS score of <7). No evidence of publication bias was found.</p><p><b>Conclusions:</b>Evidence from case-control studies suggested that a higher level of spicy food intake may be associated with an increased incidence of cancer despite significant heterogeneity. More studies are warranted to clarify our understanding of the association between high spicy food intake and the risk of cancer.</p>
