Abstract

Background and Aim: Enterococci were the first organisms which developed resistance to vancomycin. In the recent years, they have shown resistance to many antibiotics and vancomycin is one of such antibiotics. Risk factors for rectal colonization with vancomycin-resistant enterococci include patient related factors such as underlying diseases and hospital related factors such as duration of hospitalization, treatment procedures and antibiotic use. In this study the prevalence and risk factors for rectal colonization with vancomycin-resistant enterococci (VRE) in the medical and surgical wards were assessed and the results of the study in the 2 above mentioned wards were compared with each other. Material and Methods: Serial rectal swabs were obtained from 370 hospitalized patients in seven medical wards and 143 patients in five surgical wards every five days. Sampling method was stratified random sampling. During the study 750 samples of rectal swab were taken under sterile conditions. Enterococci were detected by disk diffusion method and their resistance to vancomycin was verified by minimum inhibitory concentration dilution method. Chi square and T tests were used for data analysis. Results: Among 513 patients, 76 (15%) were colonized with VRE (cases) and 40 patients with vancomycin-sensitive strains (VSE). Medical wards showed a higher rate of colonization (18.1%) in comparison to surgical wards (6.3%). In surgical wards, prevalence of VRE was related to clinical outcome (p=0.04) and major surgery (p=0.000), but in medical wards, VRE colonization showed a significant relationship with duration of hospitalization (p=0.03), underlying disease (p=0.04), the number of antibiotics (p=0.02), renal failure, history of dialysis (p=0.01) and duration of antibiotic use. Conclusion: Our study demonstrates that VRE prevalence in medical wards is three times as those of surgical wards. Considering longer period of hospitalization, use of more drugs for longer periods and also presence of underlying diseases in medical ward patients, performance of infection control strategy in regard to VRE seems necessary.

Abstract

Background and Aim: Various methods are used to analyze the data in survival studies. The aim of this study was to compare the analysis results of penalized splines in Cox model and Cox proportional hazards model in relation to the effects of prognostic factors related to the survival of renal transplant patients.
Material and Methods: This retrospective study included data of 876 renal transplant patients in Kermanshah, in Iran, from 2001 to 2015. Cox proportional hazards model and penalized splines in cox model were used. We used R version 3.3.2 for data analysis. The significance level was set at 0.05 and Akaike information criterion was used to compare the efficacy rates of these models.
Results: Using Cox proportional hazards model, one, three and five year survival rates of the patients were 94.9, 92.3 and 90.2 percent, respectively. But the corresponding figures for penalized spline model were 95.6, 93.3 and 91.4 percent. The recipient's age, postoperative creatinine, urea after surgery and underlying diabetes were significantly associated with the patients' survival rates (p < 0.05). Akaike's criteria for Cox proportional hazards model and penalized spline model were 1016.3 and 984.1, respectively.
Conclusion: Considering lower Akaike information criterion and suitability of penalized spline model for continuous variables affecting the survival of renal transplant patients, this model can be used instead of Cox proportional hazards model for more accurate estimate of survival rate of the renal transplant patients.
Key words: Survival, Renal transplantation, Cox proportional hazards model, Penalized spline model.

Abstract

Background: Extra corporeal membrane oxygenation (ECMO) has been considered as a crucial modality for the management of acute respiratory distress syndrome (ARDS). Since ECMO is considered to be an invasive modality and may be associated with some complications, there are strict indications for its use. Here we report successful treatment of a case of severe ARDS with Veno-Venous ECMO.
Case presentation: A 30 years old male was admitted to Nemazee Hospital in Shiraz with decreased level of consciousness due to cerebral hemorrhage following fibrinolytic therapy for myocardial infarction with ST elevation (STEMI).  After diagnosis of moderate to severe ARDS, VV-ECMO was used for the management of ARDS.
In this case, 5 days after starting ECMO, PaCO2 improved and O2Sat was maintained at 97-98%, so weaning was considered.  Ventilator mode was BIPAP with FiO2 40% and sweep flow was 1.7L/min. We clamped the sweep flow and observed whether the patient was able to maintain O2 Sat at 97% with ventilation alone. Then, we decided to disconnect the patient from ECMO. The patient remained stable afterwards.
Conclusion: Our case was intubated and was on MV from 10 days prior to ECMO administration.Moreover, our patient had simultaneous multi-organ involvement (nephrotic syndrome and sepsis) which decreased the benefits of ECMO. Despite all these problems, ECMO was started and patient was discharged from ICU with an acceptable health condition.

Abstract

Background and Aim: Breast cancer is the most important cause of cancer death in women. The purpose of this study was to evaluate the effect of Estrogen Receptor (ER), Human Epidermal Growth Receptor (HER2) and other factors on post-surgical survival of the patients with breast cancer using Bayesian approach for parametric proportional hazards model.
Materials and Methods: This was a retrospective study. Data of 165 breast cancer patients who had undergone surgery at Ahvaz Healing Diagnostic Center from 2004 to 2014 were recorded in a data collection form. The variables of age, tumor size, number of lymph nodes involved, cancer grade, ER status and HER2 status were evaluated. Survival time was calculated from the date of surgery to the date of death or study end date (September 2015), in months. In the Bayesian approach in parametric survival analysis models with proportional hazards, the lateral distribution of parameters was estimated using MCMC method. Also, we evaluated efficiency of the models using the deviance information criterion. All data analysis steps were performed by using Stata15 software. Significance coefficients of the model were determined using the 95% credible interval.
Results: The mean and standard deviation of age were 46.40 and 9.94 years, respectively. Deviance information criterion for Weibull parametric model was lower than those of other parametric models. Based on the Bayesian estimation of the Weibull's proportional hazards parametric model, tumor size (HR = 1.40), the number of involved lymph nodes (HR = 1.016), Ki67 status (HR = 1.115), tumor grade (HR = 1.022), HER2 status (HR = 1.760) and ER status (HR = 1.381) had a positive effect on risk of death. Age had a negative effect on risk of death (HR=0.978).
Conclusion: Based on the Bayesian proportional hazards Weibull model, tumor size, the number of involved lymph nodes, Ki67, tumor's grade, HER2 and ER had a positive effect on the risk of death.

Abstract

Background and Aim: Antibiotic resistance is considered a global and increasing threat to human health. Excessive use of antibiotics is one of the leading causes of antibiotic resistance. In this study, we investigated the frequency of antibiotic prescriptions and evaluated the aspects of its prescription in Sanandaj hospitals.
Materials and Methods: This study was part of the Global-PPS Antibiotic Consumption and Resistance Project under the management of the University of Antwerp, Belgium, in 2016 and 2018, the purpose of which was to help improvement of the rational prescription of antibiotics in hospitalized patients. The study method was based on the protocol developed by the global point prevalence survey project. All patients hospitalized in the neonatal, pediatric, and adult departments of Besat, Tohid, Kowsar, and Social Security hospitals in Sanandaj were included on the selected study days.
Results: Quality indicators of antibiotic prescription in children and adults departments consisted of the relative frequency of antibiotic prescription (57.84% and 42.57%), the relative frequency of combined treatment prescription (73.41% and 50%), use of experimental treatment vs. Targeted treatment based on microbiology evidence (4% and 2%), reference to hospital guidelines in prescribing antibiotics (3% and zero), the presence of a registered indication for prescribing antibiotic treatment (79% and 49%), and also stop/review date documented in the patient's records (1% and 2%) respectively. The quality indicators in this study were compared with those in the European and other Asian countries.
Conclusion: The quality indicators of antibiotic prescription in Sanandaj hospitals were not favorable compared to the hospitals in European and other Asian countries and indicated an urgent need for intervention by designing an antibiotic stewardship program.
