Background: Sepsis or blood stream infection is a clinical lethal syndrome with severe systemic inflammatory response to infection, if not treated quickly, is associated with dangerous consequences and high morbidity and mortality. The traditional and conventional method for identification of sepsis is blood culture method which is so time-consuming and long that it eliminates the possibility of rapid treatment. Although, new molecular methods, due to their high sensitivity, specificity, and speed, lead to the rapid and accurate and exact detection of bacterial sepsis within only a few hours. The aim of this study was diagnosis of bacteremia in patients with suspected sepsis using amplification of 23S rRNA gene by polymerase chain reaction (PCR).
Methods: This cross-sectional study was performed in two clinical and analytical steps at Shahid Beheshti University Hospital in Kashan City, Iran, in twelve months from November 2016 to December 2017. The blood samples of two hundred and fifty-six patients with suspected sepsis admitted to Shahid Beheshti Hospital were studied by PCR method using specific primers of 23S rRNA gene of the bacteria.
Results: The finding of molecular assays using PCR showed that of 256 blood samples that were collected from patients with clinical signs and symptoms of sepsis, 80 (30.2%) diagnosed with bacteremia. Of these patients diagnosed with sepsis, 46 out of 80 (57.5%) were male while 34 out of 80 (42.5%) were female. The most PCR positive results were obtained among patients with diabetes and bedsore as underlying diseases (21.3%). Statistical analysis showed that there was a significant correlation between results of molecular methods by PCR assays and history of antibiotic use. 
Conclusion: Overall, the results of the present study showed that the molecular methods such as polymerase chain reaction using universal 23S rRNA primers is an appropriated test for diagnosis of bacteremia in blood samples of patients with suspected sepsis.

Background: One of the most important duties of a family physician is primary health care. The family doctor plan is one of the developmental measures to provide easy and low-cost access for patients to health care centers. The family doctor and her team are fully responsible for the health of the individuals and families covered. Therefore, this study was conducted to assess the satisfaction of rural areas of Rafsanjan city with the family physician plan.
Methods: This study is a descriptive-analytical study that was conducted in rural areas of Rafsanjan from October to December 2018. The study population consisted of twelve randomly selected villages in Rafsanjan. The required sample size was examined according to the size of the statistical population of 480 people. In this study, to collect the required data, a researcher-made checklist was used, which was prepared by reviewing the texts of the questions. The sampling method was cluster random. To check the validity of the checklist, the opinions of 10 health education experts were used. To check the reliability, the checklist was provided to 20 villagers and the reliability was determined using Cronbach's alpha method of 82%. The mean was used to describe the data and inferential statistics t-test and ANOVA were used to analyze the data and analyzed by SPSS.
