Background and aimsChanges in lifestyle and eating habits have put women at risk of obesity and overweight more than ever. This aim of this study was to investigate the effect of Pender's Health Promotion Model (HPM) to improve the nutritional behavior of overweight and obese women admitted to Fatemiyeh Hospital clinics in Hamadan, west Iran in 2015.MethodsIn this quasi-experimental study, 108 eligible women were selected and randomly assigned to two groups: one experimental and one control. Data were gathered using three questionnaires: demographics, Pender's HPM constructs, and nutritional behavior. The questionnaires were filled out by both groups as pre-test and two months later. A Pender's HPM-based intervention was conducted on the experimental group. The data were analyzed by paired and independent t-tests, ANCOVA, and Spearmans' correlation coefficient in SPSS/16. The level of significance was considered to be <0.05.ResultsThe mean score of nutritional behavior was 41.75±3.28 and 42.36±3.69 before the intervention and 79.09±5.27 and 49.72±9.49 after the intervention in the experimental and control groups, respectively. The difference was significant only between before and after the intervention in the experimental group (P<0.001). Furthermore, the mean scores of the following variables were significantly different between before and after the intervention in the experimental group: nutritional behavior, perceived benefits, perceived self-efficacy, commitment to action, interpersonal and situational influences, affect related to behavior, and perceived barriers (P<0.001).ConclusionThe results showed that Pender's HPM-based training improved nutritional behavior and some constructs of the model. Therefore, this educative model can be used by healthcare providers to improve the nutritional and other health promoting behaviors.
Background: Despite all progresses in surgical science, bleeding caused by traffic accidents is still a challenge for surgeons to save patients' lives. Therefore, introducing an effective method to control external bleeding is an important research priority. Objectives: This study aimed to compare haemostatic effect of zinc chloride and simple suturing to control external bleeding. Materials and Methods: In this animal model study, 60 male Wistar rats were used. An incision (two cm in length and half a cm in depth) was made on shaved back of rats. The hemostasis time was measured once using zinc chloride with different concentrations (5%, 10%, 15%, 25%, and 50%) and then using simple suturing. Skin tissue was assessed for pathological changes. Due to abnormal distribution of variables in Kolmogorov-Smirnov test, the data was analyzed using Kruskal-Wallis test Mann-Whitney U tests. Results: In all the groups, complete hemostasis occurred. Hemostasis times of different concentrations of zinc chloride were significantly less than that of the control group (P < 0.001). Conclusions: Zinc chloride was effective to control external bleeding in rats.
Background: Controlling parenchymal hemorrhage especially in liver parenchyma, despite the progress in surgical science, is still one of the challenges that surgeons face when trying to save patients' lives. Researchers in the field are challenging to introduce a more effective method.Objectives: The current study aimed to determine the haemostatic effect of alum [KAl (SO 4 ) 2 ] and compare it with that of standard method, suturing technique, in controlling bleeding from liver parenchymal tissue. Materials and Methods:In this animal model study, 60 male Wistar rats were used. An incision, two centimeters long and half a centimeter deep, was made on each rat's liver and the hemostasis time was measured once using alum with different concentrations (5%, 10%, 15%, 25%, and 50%) and then the control method, controlling bleeding by suturing, was employed. The liver tissue was examined for pathological changes. Results: Complete hemostasis occurred in all the groups. There was a statistically significant difference between the two haemostatic times (P < 0.001). The haemostatic times in different concentrations of alum were significantly less than that of the control group (P < 0.001). The pathologic examination showed the highest frequency of low-grade inflammation based on the defined pathological grading. Conclusions: Alum might be an effective haemostatic agent in controlling liver parenchymal tissue hemorrhage in an animal model.
Background: Urinary catheterization is one of the main measures used to treat and care for hospitalized patients. Several complications have been attributed to the presence of latex with routine Foley catheters. Therefore, some studies have recommended that Nelatone catheters be substituted for the ordinary Foley catheters to prevent these complications. Objectives: This study aimed to compare the rates of urinary tract infection (UTI) in rabbits catheterized either with Foley or with Nelatone catheters. Materials and Methods: A randomized controlled trial was conducted on 60 rabbits that were randomly assigned to three groups of twenty. The first group was catheterized using Nelatone catheter; the second group was catheterized using Foley catheter and the third group was studied without performing any catheterization. After seven days, urine samples were collected using suprapubic aspiration and were sent to the laboratory for culture. Descriptive statistics were calculated. Moreover, chi-square and Fisher's exact tests were used for data analysis. Results: At the end of the study, four cases in the Nelatone group and 12 cases in the Foley group presented with UTI (P = 0.01). No positive urine cultures were found in the control group. Conclusions: The Nelatone catheters, compared with the Foley ones, had a lower risk of UTI in the long term use. Verifying this claim by further studies can have an important role in reducing UTIs in patients using urinary catheters.
