International journal of environmental research and public health. 2023;(3)
Abstract
This review aims to evaluate the effects of probiotic supplementation on performance and performance-related conditions in athletes by evaluating randomized controlled studies from the MEDLINE (Pubmed), Web of Science, Scopus, and SPORTDiscus (EBSCO) databases. From a total of 2304 relevant articles, 13 studies fulfilled the inclusion criteria. Seven studies concern endurance athletes, one to rugby players, three refer to non-specified athletes, one to badminton players, and one involves baseball players. The evidence suggests that the integration of athletes' diets with some bacterial strains and also the consumption of multi-strain compounds may lead to an improvement in performance and can positively affect performance-related aspects such as fatigue, muscle pain, body composition, and cardiorespiratory fitness. However, the type of supplementation and sport is very variable among the studies examined. Therefore, to obtain more solid evidence, further controlled and comparable studies are needed to expand the research regarding the possible repercussions of probiotics use on athletes' performance.

Abstract
Most women who menstruate experience various physical, psychological, and behavioral changes during the period between ovulation and menstruation. This study focuses on defining and diagnosing premenstrual disorders, distinguishing between premenstrual symptoms (PS), PMS, and premenstrual dysphoric disorder (PMDD). It highlights the prevalence of these conditions and their impact on women's quality of life, including social, occupational, and psychological aspects. Furthermore, the study examines the role of physical activity, particularly aerobic exercise, in managing premenstrual symptoms. Several systematic reviews are cited, suggesting that regular physical activity can effectively reduce both physical and psychological symptoms associated with PMS. In conclusion, the management of PMS involves a multifaceted approach, with exercises, dietary modifications, stress management, cognitive-behavioral therapy, and medications all playing roles. Physical activity, especially aerobic exercise, has been found to be an effective non-pharmacological therapy for alleviating PMS symptoms and improving overall well-being. However, more research is needed to determine the optimal type and dosage of exercise for individual women with PMS.

Abstract
Chronic kidney disease (CKD) represents a frequent comorbidity in cancer patients, especially for patients affected by urological cancers. Unfortunately, impaired kidney function may limit the choice of adequate oncological treatments for their potential nephrotoxicity or due to contraindications in case of a low glomerular filtration rate. For these patients, tailored nephrological and nutritional management is mandatory. The K-DIGO guidelines do not define whether the nutritional management of CKD could be useful also in CKD patients affected by urological cancer. In fact, in clinical practice, oncological patients often receive high-protein diets to avoid malnutrition. In our study, we investigated the nutritional and nephrological impact of a Mediterranean-like diet with a controlled protein intake (MCPD) on a cohort of 82 stage III-IV CKD patients. We compared two cohorts: one of 31 non-oncological CKD patients and the other of 51 oncological patients with CKD. The use of an MCPD had a favorable impact on both the oncological and non-oncological CKD patients with an amelioration in all the investigated parameters and with a better quality of life, with no cases of malnutrition or AKI.

Abstract
UNLABELLED Arthrospira platensis, also known as spirulina, is currently one of the most well-known algae supplements, mainly due to its high content of bioactive compounds that may promote human health. Some authors have hypothesized that spirulina consumption could protect subjects from exercise-induced oxidative stress, accelerate recovery by reducing muscle damage, and stimulate the immune system. Based on this, the main goal of this review was to critically analyze the effects of spirulina on oxidative stress, immune system, inflammation and performance in athletes and people undergoing exercise interventions. Of the 981 articles found, 428 studies were considered eligible and 13 met the established criteria and were included in this systematic review. Most recently spirulina supplementation has demonstrated ergogenic potential during submaximal exercise, increasing oxygen uptake and improving exercise tolerance. Nevertheless, spirulina supplementation does not seem to enhance physical performance in power athletes. Considering that data supporting benefits to the immune system from spirulina supplementation is still lacking, overall evidence regarding the benefit of spirulina supplementation in healthy people engaged in physical exercise is scarce and not consistent. Currently, spirulina supplementation might be considered in athletes who do not meet the recommended dietary intake of antioxidants. Further high-quality research is needed to evaluate the effects of spirulina consumption on performance, the immune system and recovery in athletes and active people.

Plain language summary
Bariatric surgery is currently the most effective method of weight loss for individuals with obesity. However sustained weight loss after surgery can be hindered by unhealthy behaviours that have sustained since before the procedure. Motivational, educational, diet and exercise programmes have been shown to help sustain weight loss following surgery. This non-randomised control trial over 12 months, aimed to assess the effects of a motivational, educational diet and exercise programme on fitness and quality of life in 82 individuals following bariatric surgery. The results showed that a diet and exercise programme improved quality of life and fitness. There was an increased daily intake of fruits and vegetables, eating behaviours were improved and there was a greater weight loss in those following the programme. It was concluded that the diet and exercise programme was responsible for behavioural changes that ensured better quality of life and sustained weight loss following surgery. Health care professionals could use this study to understand the need to recommend motivational and educationally based diet and exercise programme to patients following bariatric surgery.
Abstract
INTRODUCTION Unhealthy lifestyles may hinder bariatric surgery outcomes. This non-randomized controlled study aimed to evaluate the effects of an integrated post-operative exercise-based educational and motivational program in improving behaviors, quality of life, anthropometric features, cardiorespiratory and physical fitness in bariatric patients respect to the only surgical intervention. METHODS A group of adult sedentary bariatric patients chose to attend a 12-month exercise program integrated with diet education and motivational support, or to receive usual care. Dietary habits, binge eating disorder, physical activity, obesity-related quality of life, Body Mass Index, waist and hip circumference, VO2max, strength and flexibility were assessed at the start and at the end of the study in both groups. RESULTS On a total of 82 patients enrolled, follow-up measures were obtained from 28 (85.7% females, mean age 38.2±8.7) and 42 (71.4% females, mean age 40.2±9.5) patients included in the intervention and control group, respectively. All the behavioral and physical outcomes improved significantly in the participants to the intervention, while the control group showed lesser changes, especially regarding quality of life and physical fitness. CONCLUSIONS Notwithstanding the self-selection, these results suggest that a timely postoperative behavioral multidisciplinary program for bariatric patients may be effective in establishing healthy behaviors which can lead to better surgery outcomes.

Abstract
PURPOSE This study aimed to evaluate the prevalence of traits of orthorexia nervosa (ON) and muscle dysmorphia (MD) in a group of undergraduates, investigate the associations between the risk of these conditions and the type of university course attended, the individual characteristics (gender, BMI, amount of physical activity, supplements and medicines use, dieting) and the risk of eating disorders (EDs). METHODS A self-reported questionnaire consisting of a socio-demographic section and three tests validated for the evaluation of a risk of ON (ORTO-15), MD (MDDI-ITA) and EDs (EAT-26) was completed by 918 students from three Italian universities. RESULTS 29.0% of participants demonstrated traits of ON and 5.0% of MD, without differences in prevalence in the three areas of study investigated (health-scientific, economic-humanistic, sport sciences); students of sport sciences exhibited a significantly higher score for MDDI-ITA (F = 6.493, p = 0.002). Participants with ON and MD traits were more on a diet (OR = 0.47, p ≤ 0.001 and OR = 0.428, p = 0.020, respectively) and showed a higher prevalence of EDs risk (OR = 3.55, p < 0.001 and OR = 10.23, p ≤ 0.001, respectively). The simultaneous presence of ON, MD, and EDs traits was seen in 5.4% of the students and the three test scores were correlated. CONCLUSIONS The prevalence of ON and MD traits was found similar to that reported in the literature on undergraduates. Some associations observed improvement in the knowledge about these conditions, especially the association of participants with ON and MD traits with dieting and EDs traits and the correlation of the three test scores suggests a connection among these potential conditions.
