RESUMEN
PURPOSE: This study aimed to assess the effectiveness of ozone therapy in treating Diabetes-related Foot Ulcer (DFU) and its outcomes. METHODS: A systematic search was conducted in PubMed/MEDLINE, Scopus, Web of Science, and ProQuest databases for published studies evaluating the use of ozone as an adjunct treatment for DFU, from inception to December 21, 2022. The primary outcome measure was the change in wound size after the intervention compared to pretreatment. Secondary outcomes included time to complete ulcer healing, number of healed patients, adverse events, amputation rates, and hospital length of stay. Quantitative data synthesis for the meta-analysis was performed using a random-effects model and generic inverse variance method, while overall heterogeneity analysis was conducted using a fixed-effects model. Interstudy heterogeneity was assessed using the I2 index (<50%) and the Cochrane Q statistic test. Sensitivity analysis was performed using the leave-one-out method. RESULTS: The meta-analysis included 11 studies comprising 960 patients with DFU. The results demonstrated a significant positive effect of ozone therapy on reducing foot ulcer size (Standardized Mean Difference (SMD): -25.84, 95% CI: -51.65 to -0.04, p = 0.05), shortening mean healing time (SMD: -38.59, 95% CI: -51.81 to -25.37, p < 0.001), decreasing hospital length of stay (SMD: -8.75, 95% CI: -14.81 to -2.69, p < 0.001), and reducing amputation rates (Relative Risk (RR): 0.46, 95% CI: 0.30-0.71, p < 0.001), compared to standard treatment. CONCLUSION: This meta-analysis indicates that ozone therapy has additional benefits in expediting complete DFU healing, reducing the amputation rates, and decreasing hospital length of stay, though its effects do not differ from standard treatments for complete ulcer resolution. Further research is needed to address the heterogeneity among studies and to better understand the potential beneficial effects of ozone therapy.
RESUMEN
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has been shown to affect nutritional recommendations. Some functional foods have been demonstrated to be useful in the treatment of people with COVID-19. However, little is known about the impact of combining functional foods on disease control. This study aimed to investigate the effects of functional foods mixture on serum levels of inflammatory cytokines and biochemical findings in patients with COVID-19. METHODS: A randomized double-blind controlled trial was conducted in Baqiyatallah Al-Azam hospital in Tehran, Iran. Sixty patients were randomly assigned to receive either a soup containing functional foods (n = 30) or a usual soup (control group) (n = 30). Participants' sociodemographic information was gathered using a general questionnaire. Blood levels of inflammatory markers and biochemical findings were assessed using standard protocols. RESULTS: The results showed that soup containing functional foods was more effective in controlling serum levels of D-dimer, blood urea nitrogen, and creatinine than the control group (P < 0.05). Also, more significant improvement was found in the intervention group vs control group in terms of interleukin (IL)-1ß, IL-6, IL-17, IL-10, and tumor necrose factor-α (P < 0.05). In contrast, the control intervention more efficiently controlled potassium levels and reduced quantitative C-reactive protein than the intervention group (P < 0.05). CONCLUSIONS: This study indicates a soup containing functional foods could alleviate biomarkers of inflammation in patients with COVID-19. However, its effectiveness on biochemical findings remained inconclusive which warranted further research. TRIAL REGISTRATION: IRCT, IRCT20180201038585N11.

PURPOSE: Patients with multiple traumas are at high risk of developing respiratory complications, including pneumonia and acute respiratory distress syndrome. Many pulmonary complications are associated with systemic inflammation and pulmonary neutrophilic infiltration. Leukotriene-receptor antagonists are anti-inflammatory and anti-oxidant drugs subsiding airway inflammation. The present study investigates the effectiveness of montelukast in reducing pulmonary complications among trauma patients. METHODS: This randomized, double-blind, placebo-control trial was conducted in patients with multiple blunt traumas and evidence of lung contusion detected via CT scan. We excluded patients if they met at least one of the following conditions: < 16 years old, history of cardiopulmonary diseases or positive history of montelukast-induced hypersensitivity reactions. Patients were allocated to the treatment (10 mg of montelukast) or placebo group using permuted block randomization method. The primary measured outcome was the volume of pulmonary contusion at the end of the trial. The secondary outcomes were intensive care unit and hospital length of stay, ventilation days, multi-organ failure, and the in-hospital mortality rate. RESULTS: In total, 65 eligible patients (treatment = 31, placebo = 34) were included for the final analysis. The treatment group had more pulmonary contusion volume (mean (SD), mm3) at the right (68726.97 (93656.54) vs. 59730.27 (76551.74)) and the left side (67501.71 (91514.04) vs. 46502.21 (80604.21)), higher initial C-reactive peptide level (12.16 (10.58) vs. 10.85 (17.87)) compared to the placebo group, but the differences were not statistically significant (p > 0.05). At the end of the study, the mean (SD) of pulmonary contusion volume (mm3) (right side = 116748.74 (361705.12), left side = 64522.03 (117266.17)) of the treatment group were comparable to that of the placebo group (right side = 40051.26 (64081.56), left side = 25929.12 (47417.13), p = 0.228 and 0.082, respectively). Moreover, both groups have statistically similar hospital (mean (SD), days) (10.87 (9.83) vs. 13.05 (10.12)) and intensive care unit length of stays (mean (SD), days) (7.16 (8.15) vs. 7.82 (7.48)). Of note, the frequency of the in-hospital complications (treatment vs. control group) including acute respiratory distress syndrome (12.9% vs. 8.8%, p = 0.71), pneumonia (19.4% vs. 17.6%, p = 0.85), multi-organ failure (12.9% vs. 17.6%, p = 0.58) and the mortality rate (22.6% vs. 14.7%, p = 0.41) were comparable between the groups. CONCLUSION: Administrating montelukast has no preventive or therapeutic effects on lung contusion or its complications.

PURPOSE: Unidentified dynamics for the causative agent of COVID-19, SARS-Cov-2, led to the critical public health issue. Suspicion for the airborne potential of SARS-Cov-2 is an important problem for its transmission and relevant epidemics. This research investigated hospital indoor air quality to SARS-Cov-2 occurrence and determination its air born potential. METHODS: The site study was a referral hospital with 630 beds for admitting of COVID-19 patients. Air sampling was done (n = 31) on selected wards including Emergency 1, Emergency 2, bedridden (4-B, 10-D), ICU 2, ICU 3, CT-SCAN, and laundry. The average temperature and relative humidities were 22 ± 1 °C and 43 percent respectively. All glass impinger used for sampling in which the sampling pumps capacities were 5 and 40 L.min- 1. Sampling duration time was 20 and 15 minutes and 100 to 1000 L of air were gathered. All parts of the sampling equipment were completely disinfected by hot water, ethanol (70%), chlorine solution (1000 ppm), hot water (70 °C for 1 min) and washed with distilled water. The transmitting media (7 ml) was injected into impinger and residual of this media (2 ml) was sent to the virology laboratory within 2 hours and preserved on refrigerator < 4 °C. Analysis of samples was performed by RT-PCR and repeated for accuracy control. RESULTS: All of the samples were negative for SARS-Cov-2 occurrence. These results showed that SARS-Cov-2 had not airborne potential in this hospital. CONCLUSIONS: Although SARS-Cov-2 similar to the SARS virus but, SARS-Cov-2 is not an airborne virus.
RESUMEN
BACKGROUND: An outbreak of COVID-19 in Iran has spread throughout the country. Identifying the epidemiological characteristics of this disease will help to make appropriate decisions and thus control the epidemic. The aim of this study was characterization of the epidemiological features of COVID-19 in Iran. METHODS: In this retrospective study, data related to the epidemiological characteristics of COVID-19 patients admitted to Baqiyatallah Hospital in Tehran, Iran, from 19 February 2020 to 15 April 2020 have been analyzed and reported. Patient characteristics including age, gender and underlying diseases were investigated. Data were collected through patient records. Sex ratio, Case Fatality Rate (CFR) and daily trend of cases were also determined. A multiple logistic regression analysis was also performed to assess affecting factors on mortality. RESULTS: From February 19, 2020 to April 15, 2020, 12870 patients referred to the hospital emergency department, of which 2968 were hospitalized with COVID-19 diagnosis. The majority of cases were in the age group of 50 to 60 years of old. The male-to-female ratio was 1.93:1. A total of 239 deaths occurred among all cases for an overall CFR of 1.85% based on the total number of patients (both outpatient and inpatient) and 8.06% among hospitalized patients. Out of all patients 10.89% had comorbidity. Diabetes, chronic respiratory diseases, hypertension, cardiovascular diseases, chronic Kidney diseases and cancer were the most common comorbidities with 3.81, 2.02 , 1.99 , 1.25, 0.60 and 0.57 %, respectively. Male gender (OR=1.45, 95% CI: 1.08-1.96), older age (OR=1.05, 95% CI: 1.04-1.06) and having underlying diseases (OR=1.53, 95% CI: 1.04-2.24) were significantly associated with mortality. CONCLUSIONS: The results of this study showed that Male gender, older age and having comorbidities were significantly associated with the risk of death among COVID-19 patients. It is important to pay special attention to male elderly patients with underlying diseases.

BACKGROUND: Obstructed defecation syndrome (ODS) occurs in about 7% of adults; it seems that the etiology of pelvic floor disorders is multifactorial. Pregnancy and childbirth damage to the pelvic nerve and muscles are proposed causes for this condition. The precise role of vaginal delivery (VD) is not clearly defined, although in recent studies association of pelvic floor disorder with Operative vaginal delivery and episiotomy has been proposed. OBJECTIVES: In this prospective study, we assessed the outcome of stapled transanal rectal resection (STARR) in females with one of the two modes of delivery (VD or caesarean section (C/S). PATIENTS AND METHODS: We used Longo's ODS score for the assessment of the severity of pelvic floor malfunction. Stapled Trans Anal Rectal Resection (STARR) procedure was performed using two circular staplers. Follow-up was done 12 months after the discharge. To assess the role of episiotomy in patient with VD, we divided them into two subgroups; females who had VD with episiotomy (Vd + epi) and females who had VD alone. Data were analyzed using SPSS version 20 software. P values less than 0.05 were considered statistically significant. RESULTS: In 30 consecutive females undergoing STARR for the treatment of ODS, who enrolled in this prospective study, 19 (63.3%) had Vaginal Delivery VD and 11 (36.7%) had Cesarean Section (C/S). The ODS score before the surgery was higher in females who had C/S, although there was no significant difference between VD and C/S groups in terms of the percentage of the ODS score improvement after the STARR surgery. CONCLUSIONS: Higher ODS score in females who had C/S showed that C/S could not protect the pelvic organ from pregnancy and delivery trauma. It seems that episiotomy has a protective effect during VD; it can reduce the severity of trauma in pelvic organs during childbearing.
