Background and Objective: Campylobacter is one of the most important pathogens causing bacterial gastroenteritis, which is usually transmitted through the food of animal origin. This study was done to evaluate the status of Campylobacter in diarrheal food outbreaks compared to other microbial agents.
Methods: This descriptive study was performed on 305 diarrheal swab samples from 102 food outbreaks during six months from spring to the end of summer 2018. Presence of Campylobacter species were assessed according to the protocol of the General Directorate of Laboratory Affairs.
Results: Out of 305 samples, 8 (2.6%) were identified as Campylobacter species, 3 (37.5%) Campylobacter and 5 (62.5%) Campylobacter coli. The epidemiology of the outbreaks showed that female (54.5%), average age of 16-30 years (28.2%), consumption of salads and vegetables (16.1%) and living in the cities (59.7%) were the most cases.
Conclusion: This study showed that in addition to classic pathogens such as Salmonella, Shigella, Escherichia coli, attention also should be paid to Campylobacter bacteria. In addition, recognizing epidemiological factors can play an important role in preventing and controlling food outbreaks.

Background and Objective: Middle age is associated with various biopsychosocial changes. Sexual health is one of the most important aspects of health, which is less addressed in middle age. The study aimed to determine the relationship between sexual self-concept and sexual health in middle-aged women in Gorgan, Iran.
Methods: This descriptive-analytical study was carried out on 428 eligible married women (mean age: 46.38±5.46 years) who had electronic records in one of the comprehensive health centers of Gorgan, Iran. Data collection was done in 2019 using a demographic checklist, the Persian version of Snell’s multidimensional sexual self-concept questionnaire, and the sexual health of middle-aged women scale.
Results: The mean score of sexual self-concept was 115.10±26.88 in the positive domain, 18.09±11.22 in the negative domain, and 39.92±11.88 in the situational domain. The mean score of sexual health was 129.18±18.71. There was a significant positive correlation between sexual health and the positive (r=0.67, P<0.001) and situational sexual self-concept (r=0.63, P<0.001). There was also a significant inverse correlation between sexual health and negative sexual self-concept (r=-0.48, P<0.001).
Conclusion: This study showed that the sexual health of married middle-aged women has a direct relationship with the positive sexual self-concept and an inverse relationship with the negative sexual self-concept.

Background and Objective: Weight regain following bariatric surgery is a significant challenge for this obesity treatment method. This study aimed to identify factors associated with weight regain after bariatric surgeries in obese patients in Gorgan, Iran.
Methods: This longitudinal study included 143 obese individuals (125 women and 18 men) with a mean age of 43.13±9.83 years who underwent bariatric surgery in Gorgan, Iran during 2013-19. Participants were invited to join the study via phone calls. Research variables (type of surgery, blood group, pre-surgery weight, and body mass index [BMI]) were extracted from patient records, and their current weight and waist circumference were measured and recorded. Weight regain was determined based on one of three different criteria: (1) regaining more than 25% of the maximum weight lost post-surgery, (2) regaining more than 10 kg from the minimum weight post-surgery, or (3) an increase of more than 5 BMI units from the lowest BMI post-surgery.
Results: Overall, 33% of individuals experienced weight regain, with 26.6% according to the first definition, 29.4% according to the second definition, and 18.2% according to the third definition. Men had a higher rate of weight regain (P<0.05). Additionally, 93.6% (44 cases) of those with weight regain had abdominal obesity. On average, 79.7% of participants who were 48 months post-bariatric surgery experienced some degree of weight regain. Individuals with a pre-surgery BMI of 50 or higher had a 2.69 times greater chance of weight regain compared to those with BMI lower 50 (P<0.05). The mean weight loss after surgery was significantly higher in individuals who experienced weight regain than those who did not (P<0.05). There was no significant statistical association between weight regain and the type of surgery, age, education level, marital status, or blood group.
Conclusion: Weight regain over time is a reality after bariatric surgery, indicating that this method is not a definitive cure for obesity. Therefore, long-term follow-up for weight control is crucial, especially for individuals with a pre-surgery BMI of 50 or higher or those who experienced significant weight loss post-surgery.
