Aim To investigate the relationship between adherence to preventive behaviors and risk of COVID-19 infection. Methods In this case-control study, 491 participants were selected through convenience sampling. First, the samples of the case group (COVID-19 patients) were selected, and then the control group was matched with the case group based on age, gender, and occupation. The criteria for diagnosing COVID-19 for the case group were self-reported positive PCR test or lung involvement on a chest CT scan. Descriptive statistics were used to summarize the results, and an odds ratio was calculated to quantify the magnitude of the association using a 95% confidence interval (CI) and a p<0.05. Results The results showed that, compared to those who always wear a mask, the risk of contracting SARS-CoV-2 was 3.153 times higher in those who used no masks (95% CI: 0.953-10.434) and 3.779 times higher in those who used masks occasionally (95% CI:1.929-7.37). The participants who never observed physical distancing and handwashing were 2.25 times more likely to get COVID-19 than those who always observed (95% CI:1.719-4.954; OR=2.258). Conclusion Participants who fail in following the protective measures, especially wearing a mask regardless of its type, had a higher risk of COVID-19 infection. Therefore, it is recommended to use a mask consistently, especially during the peak of COVID-19 waves., (Copyright© by the Medical Assotiation of Zenica-Doboj Canton.)

Background: Patients with chronic renal failure are commonly cared using a blood filtration mechanism like hemodialysis. Little information is available regarding ocular changes following hemodialysis for people with chronic renal failure. Accordingly, this study intended to estimate the pre- and post-hemodialysis thickness of retina and choroid and other ocular findings in patients with chronic renal failure., Methods: This research is a "before and after" clinical experiment, without control. This prospective study was conducted on patients with chronic renal failure who were in Imam Khomeini Hospital for hemodialysis in 2017. The sample size of this study was estimated to be 67 (134 eyes). In this study, after acquiring consent (by the associated assistant) from all patients, thorough ocular examinations including IOP control, VA and fundus examination, reflection, and macula and choroid OCT were performed 30 min before and after hemodialysis and entered in SPSS V. 16 software by the project manager. Finally, these data were analyzed practicing T-pair tests or their nonparametric equivalent, the Wilcoxon test., Results: Based on the results of this examination, studying 67 participating patients, 134 eyes were examined, of which 80 eyes (59.8%) belonged to men, and 54 eyes (40.2%) belonged to women. The mean and standard deviation of participants' age in the study was reported to be 57.3 ± 15 years, and the dialysis duration was 3.0 ± 2.11 h. According to the Wilcoxon test, the average rank in terms of weight, patient temperature, pulse, blood sugar, urea, potassium, ocular pressure, 500-micron nasal choroidal thickness, and myopia in diopter vary significantly before and after dialysis (p < 0.05). However, according to the Wilcoxon test, choroidal thickness in the subfoveal area of the eye (p = 0.600), the retinal thickness in the subfoveal area (p = 0.839), the amount of astigmatism in diopter (p = 0.757) and the amount of hypermetropia in diopter (p = 0.068) before and after dialysis do not have a significant difference. Based on the t test, it was reported that the average creatinine score, the best corrected vision, and the 500 and 1000-micron temporal and nasal choroidal thickness had a significant difference (p < 0.05)., Conclusion: Based on the results of the current study, it was settled that the corrected vision, ocular pressure, as well as the 500-micron nasal choroidal thickness, and myopia in diopter and the 1000-micron temporal and nasal choroidal thickness of patients before and after hemodialysis vary. This difference shows the impact of hemodialysis on changes in ocular characteristics in patients with renal insufficiency.

The aim of this study was to determine the effect of massage of acupoints on pain and anxiety caused by venipuncture. In this double-blind clinical trial, 187 patients who were admitted to a hospital in Khorramabad, Iran, were selected and randomly divided into 3 groups: acupressure, placebo, and control. Blood samples were obtained twice from each patient in the 3 groups: once by the routine method from the left arm and once by performing interventions from the right arm. Results showed significant differences in pain scores (P = .004) between the 3 groups after the intervention only. No significant differences between the 3 groups were found after the intervention with regard to pulse rate, systolic blood pressure, or diastolic blood pressure (P > .05). The application of acupressure at the right acupoints may relieve pain caused by venipuncture. Although further studies are needed to confirm the findings of this study, it is recommended that nurses use this safe method to increase quality of nursing care and patient satisfaction.
