Background: Nurses are more likely to be exposed to violence at their workplace in comparison with other employees. Objective: To determine various aspects of violence against nurses in Shiraz public hospitals. Methods: This cross-sectional study was conducted from 2017 to 2018, using a multistage random sampling method. Violence including verbal threats, verbal abuse, physical and sexual abuse as well as ethnical types, violence from patients, patients' companions and coworkers, and causes of violence were investigated using a checklist. Results: 405 nurses with a mean age of 30.2 (SD 7.1) years and female to male ratio of 4.2 were interviewed. 363 (89.6%) nurses had experienced at least one kind of violence; 68.4% suffered from more than one type of violence. Verbal abuse (83.9%), verbal threats (27.6%), physical violence (21.4%), sexual abuse (10.8%), and ethnical harassment (6.1%) were the most common types of violence experienced by the nurses. Patients' companions, patients, and physicians were reported as the sources of violence in 70.6%, 43.1%, and 4.1% of cases, respectively. Nurses with non-official employment status and non-Farsi ethnicity, having a disease, with non-evening shift work, and those with short or long employment period were more affected. Unrealistic expectations by patients' companions and long working hours were the most common attributing factors. Conclusion: Violence against nurses, as a strenuous and health-threatening crisis, has become epidemic in public hospitals in our region. Effective interventions are warranted to sort out these problems.

Nowadays, acupuncture is widely used to manage pain, and childbirth is a condition requiring appropriate pain management interventions. The efficacy of acupuncture in the management of labor pain has recently been studied, but the results are not satisfactory and conflicts exist. In this study, we investigated the effects of acupuncture on labor pain, serum cortisol level, and duration of labor. We conducted a randomized, single-blind, controlled trial that included 63 nulliparous women: 32 in the study group and 31 in the control group. Acupuncture was performed at the SP-6 and the LI-4 points in the study group, and sham acupuncture was performed at the same points in the control group. Pain scores and serum cortisol levels were measured before and after the intervention. Changes in these measures and in the duration of labor were compared between the groups. No significant variations in pain scores or serum cortisol levels were observed between the two control groups. However, the duration of labor was significantly lower (p < 0.001) in the group receiving real acupuncture. Our results show that acupuncture is significantly associated with a decreased duration of labor, even though it was no better than a placebo for the treatment of labor pain.

The aim of this study was to investigate the variability of the voriconazole plasma level and its relationships with clinical outcomes and adverse events among liver transplant recipients to optimize the efficacy and safety of their treatment. Liver transplant recipients treated with voriconazole were included, and voriconazole trough levels were quantified by a validated high-performance liquid chromatography method. Cytochrome P450 genotypes for CYP2C19 were evaluated in allograft liver tissues. A total of 832 voriconazole trough levels from 104 patients were measured. Proven, probable, and possible invasive fungal infections were reported for 8/104 (7.7%), 42/104 (40.4%), and 54/104 (51.9%) patients, respectively. Receiver operating characteristic (ROC) curve analysis indicated that trough concentrations of ≥1.3 μg/ml minimized the incidence of treatment failure (95% confidence interval [CI], 0.68 to 0.91 μg/ml) ( < 0.001) and that those of <5.3 μg/ml minimized the incidence of any adverse events (95% CI, 0.83 to 0.97 μg/ml) ( < 0.001). Voriconazole trough levels were significantly higher for heterozygous extensive metabolizers, poor metabolizers, and individuals receiving coadministration with proton pump inhibitors. For ultrarapid metabolizers, oral administration of voriconazole, and concomitant use of glucocorticoids, voriconazole blood concentrations were significantly reduced. Furthermore, there was no statistically significant association of patient age, weight, or gender or coadministration of tacrolimus and cyclosporine with the voriconazole trough level. In conclusion, the results of our analysis indicate large inter- and intraindividual variabilities of voriconazole concentrations in liver transplant recipients. Voriconazole trough concentrations of ≥1.3 μg/ml and <5.3 μg/ml are optimal for treatment and for minimization of adverse events. Optimization of drug efficacy and safety requires the use of rational doses for voriconazole therapy.

Background. In this study, we report the epidemiology of COVID-19 among recipients of organ transplantation and evaluate associated factors with death. Methods. We screened 6969 patients who had organ transplantations in our center for COVID-19. Specific data on presentation, clinical course, treatment, and prognosis were acquired. Results. We found 85 patients (66 liver, 16 kidney, 2 kidney-pancreas, and 1 liver-kidney recipient) who acquired COVID-19. Most common symptoms included fever (48.2%), cough (41.2%), myalgia (41.2%), and fatigue (40%). Dyspnea developed in 33% of patients. Overall, one-third of patients had an oxygen saturation of below 90% on admission. Patients were hospitalized for a median (interquartile range) of 9 (5, 13.7) days and had a 33.9% intensive care unit admission rate. Overall, 17 patients (20%) died, which included 31.3% of patients with kidney transplantations and 18.2% of patients with liver transplantations. All 4 pediatric patients in our series died. In our univariate analysis among adults, rates of leukopenia (38.4% versus 13.2%; P = 0.04), low albumin levels (53.8% versus 10.2%; P = 0.001), and shorter duration between transplantation and COVID-19 (P = 0.02), were higher among patients who died. In our least absolute shrinkage and selection operator regression model, low albumin levels (OR, 4.48; 95% confidence interval, 1.16-17.27) were associated with higher risk of death. Conclusions. This is the largest single-center report on abdominal transplantations and COVID-19. Liver and kidney transplant recipients have an increased risk of mortality compared with the general population due to COVID-19. More specifically, pediatric patients and those with low albumin levels are at higher risks of death due COVID-19.

We used to LASSO-Cox method for determining prognostic factors of male breast cancer survival and showed the superiority of this method compared to Cox proportional hazard model in low sample size setting. In order to identify and estimate exactly the relative hazard of the most important factors effective for the survival duration of male breast cancer, the LASSO-Cox method has been used. Our data includes the information of male breast cancer patients in Fars province, south of Iran, from 1989 to 2008. Cox proportional hazard and LASSO-Cox models were fitted for 20 classified variables. To reduce the impact of missing data, the multiple imputation method was used 20 times through the Markov chain Mont Carlo method and the results were combined with Rubin's rules. In 50 patients, the age at diagnosis was 59.6 (SD=12.8) years with a minimum of 34 and maximum of 84 years and the mean of survival time was 62 months. Three, 5 and 10 year survival were 92%, 77% and 26%, respectively. Using the LASSO-Cox method led to eliminating 8 low effect variables and also decreased the standard error by 2.5 to 7 times. The relative efficiency of LASSO-Cox method compared with the Cox proportional hazard method was calculated as 22.39. The19 years follow of male breast cancer patients show that the age, having a history of alcohol use, nipple discharge, laterality, histological grade and duration of symptoms were the most important variables that have played an effective role in the patient's survival. In such situations, estimating the coefficients by LASSO-Cox method will be more efficient than the Cox's proportional hazard method.

Our results provided a threshold range of WTP and insights into rigorous scientific decision making about healthcare technology for the future.
