One of the applications of honey is in wound healing. A stapler normally connects the skin graft to the underlying bed. Due to its high cost and lack of production in Iran, and causing physical damage to the tissue, an alternative method is needed.

This study aims to compare the effects of using medical honey and staplers for skin graft fixation in patients with burn wounds in the north of Iran.

In this clinical trial, 80 patients with deep second-degree and third-degree burns less than 40% of total body surface area were included and were randomly divided into two groups of honey (n=40) and stapler (n=40). Demographic information and the percentage of burns were extracted from patients’ medical files. The graft rejection, number of hospitalization days, grafted skin displacement, graft contracture, pain severity, existence of edema or hematoma, itching severity, and infection after grafting were investigated and recorded.

Of 80 patients, 34 were male (42.5%) and 46 were female (57.5%). The mean age of the patients was 39.29±15.42 years. A significant difference was observed in the mean number of hospitalization days after grafting (P<0.001), incidence of infection, hematoma, edema, and severity of pain and itching (P<0.001), which were lower in the honey group. The graft contracture rate was lower in the stapler group (P<0.001). Graft rejection was not observed in any groups.

The use of medical honey for skin graft fixation reduces the duration of hospitalization and adverse effects such as pain, itching, edema, hematoma, and infection compared to staplers. This method is as efficient as the routine treatment.

Burn trauma is a life-threatening incident that may be accompanied by several risk factors thatincrease morbidity and mortality. Drug abuse is one of the lifestyle dangers on the rise globally and can havean impact on the outcomes of burn injuries. This study aimed to evaluate the effect of drug abuse on the clinicaloutcomes of adult burn patients who were admitted to a burn center in the North of Iran. This retrospective cross-sectional study included adult burn patients who were referred to VelayatHospital, between March 1, 2021, and March 20, 2022. The hospital information system (HIS) was used toselect patients with a history of drug use and then were compared with burn victims who had never used drugsbefore. In both groups, demographic information, the cause of the burn, the comorbid diseases, total bodysurface area, length of stay, and outcomes were collected and recorded for both groups. This study included 114 inpatients, 90 of whom (78.95%) were men. The mean age of the patients was43±15 years. The mean length of hospitalization in the drug-user group was significantly higher than in thenon-drug abuse group (p=0.004). The drug abuse group had significantly higher rates of comorbid diseases(p=0.021), inhalation injury (p<0.001), mortality (p=0.002), and pneumonia (p<0.001). However, there were nostatistically significant differences in the Infection and Sir’s rates (p=0.583) between the groups. Drug abuse is a risk factor in adult burn patients, which can affect the length of stay and burnrelated morbidities.

To evaluate the spiral chest computed tomography (CT) scan findings in patients with multipletrauma during the COVID-19 pandemic. This retrospective study was performed on multiple trauma patients admitted to a tertiary hospital inthe north of Iran in 2020. All patients with multiple trauma who had undergone a chest spiral CT were includedin this study. Furthermore, the data analysis was performed through descriptive and analytical statistics usingSPSS software. A total of 600 patients were included over the study period. The mean age of patients was 48.2±20.3years. Of the total, 496 (65.3%) patients had blunt chest injuries, and 104 (34.7%) had penetrating chest injuries.Falling was the most common mechanical cause of chest trauma in 270 patients (45%). Surgical interventionswere performed in 110 (18.3%) patients. A total of 276 (46%) patients had chest injuries identified by CTscans. Many patients (15.6%) had ground-glass lung opacity in the CT scan reports. Lung consolidation,pneumothorax, lung contusion, hemothorax, and rib fractures were the most common. Due to the high frequency of typical findings in spiral CT scan examinations, obtaining a reliablehistory of trauma severity, injury mechanism, and a detailed physical examination is recommended beforeprescribing a CT scan for patients.

Forecasting the future status for underlying systems or random process, is one of the most important problems. In such situations, in addition to variables, the parameters may vary during the time and hence, the independence assumption between variables and parameters is broken. For analyzing this systems, usually the dynamic generalized linear models are used based on Markov chain Monte Carlo algorithm. The purpose of this paper is applying the Bayesian dynamic generalized linear models in non-conjugate discrete structures. First, the concepts of dynamic generalized linear models are reviewed. Then, the Bayesian modeling of non-conjugated discrete structures using MCMC algorithm is studied. Finally, using the investigated model the real data set related to the economic activity condition in three provinces of Iran during the years 2006-2008 are analysed.
