Plain language summary
IBS, also known as irritable bowel syndrome, is a debilitating condition characterised by abdominal pain, irregular bowel movements, and changes in the consistency of stool. Symptoms of IBS may appear shortly after eating a meal. Excluding foods high in FODMAP carbohydrates, such as fermentable oligo- and di-saccharides, mono- and disaccharides, and polyols, or following an elimination rotation diet to reduce IgG-dependent food hypersensitivity, which has been shown to improve IBS symptoms previously. The purpose of this open-label study is to investigate the effectiveness of a low-FODMAPS diet and an elimination rotation diet based on IgG as well as a control diet in reducing symptoms of IBS. During the eight-week study, 73 female subjects with a mix of IBS were assigned to either of the three dietary treatments. Compared to the other diet groups, the IgG based elimination rotation diet group showed a significant improvement in the IBS symptoms and comorbid symptoms after the intervention period. In order to determine whether IgG-mediated food hypersensitivity plays a role in IBS and the efficacy of an IgG-dependent elimination rotation diet in the general population, further robust research is required. Healthcare professionals, however, can make use of these results to gain a better understanding of how an IgG based elimination diet tailored to each individual can improve IBS symptoms.
Abstract
Irritable bowel syndrome (IBS) is a chronic disease with recurrent abdominal pain, disturbed bowel emptying, and changes in stool consistency. We compared the effectiveness of three different dietary treatment plans (G1-FM-low FODMAP diet, G2-IP IgG based elimination-rotation-diet, and as control group, the G3-K control diet recommended by an attending gastroenterologist) in treating patients diagnosed with mixed irritable bowel syndrome. A total of seventy-three female patients diagnosed with a mixed form of irritable bowel syndrome (IBS-M) were enrolled in the study. The diet of each patient in Group 1 (G1-FM) and 2 (G2-IP) was determined individually during a meeting with a dietitian. Patients from Group 3 (G3-K) received nutrition advice from a gastroenterologist. Significant differences in the reduction of IBS symptoms were found between the groups. IBS symptoms as well as comorbid symptoms significantly improved or disappeared completely in the G2-IP group (idiopathic abdominal pain, p < 0.001; abdominal pain after a meal, p < 0.001; abdominal pain during defecation, p = 0.008), while in the G1-FM group, some of the IBS symptoms significantly improved (mucus in stool, p = 0.031; bloating, p < 0.001). In group G3-K no significant improvement was seen. Based on the results of this open-label study, it was concluded that various dietary interventions in the treatment of IBS-M patients do not uniformly affect the course and outcomes of disease management. Rotation diets based on IgG show significantly better results compared to other diets.

Abstract
Use of probiotic supplements, the benefits of which have not been proven in sportspeople, is becoming more widespread among runners. The aim of this study was to evaluate the effect of a multi-strain probiotic on body composition, cardiorespiratory fitness and inflammation in the body. The randomised, double-blind study included 66 long-distance runners. The intervention factor was a multi-strain probiotic or placebo. At the initial and final stages of the study, evaluation of body composition and cardiorespiratory fitness was performed and the presence of inflammation determined. In the group of men using the probiotic, an increase in lean body mass (p = 0.019) and skeletal muscle mass (p = 0.022) was demonstrated, while in the group of women taking the probiotic, a decrease in the content of total body fat (p = 0.600) and visceral fat (p = 0.247) was observed. Maximum oxygen consumption (VO2max) increased in women (p = 0.140) and men (p = 0.017) using the probiotic. Concentration of tumour necrosis factor-alpha decreased in women (p = 0.003) and men (p = 0.001) using the probiotic and in women (p = 0.074) and men (p = 0.016) using the placebo. Probiotic therapy had a positive effect on selected parameters of body composition and cardiorespiratory fitness of study participants and showed a tendency to reduce inflammation.

Summary Review:
This study sets out to explore the psychobiotic potential of the probiotic strain Lactobacillus Plantarum 299v (LP299v), a common single strain probiotic supplement. Depression symptoms, cognitive function and biochemical parameters were assessed in 79 patients with MDD undergoing conventional treatment with SSRIs in this double-blind placebo-controlled trial over a period of 8 weeks. Various outcome measures were used to assess the severity of depression and cognitive function, and various biochemical parameters such as tryptophan, kynurenine and cortisol were monitored. Results showed there was a significant decrease in kynurenine concentration and an improvement in cognitive function in the LP299v group compared to placebo.
Clinical practice applications:
The small sample size and short trial period of 8 weeks are limitations to this study, however, the results are important and certainly warrant more research in this area. A focus on microbiome modulation over a longer period of time may be useful to give us insight into the multidirectional interactions of the gastrointestinal microbiome and the central nervous system.
Considerations for future research:
This study suggests that patients being treated with SSRIs for MDD may see a significant improvement in cognitive performance and a decrease in the breakdown of the important amino acid l-tryptophan (from the decrease in kynurenine concentration results) if they supplement with LP299v alongside. Therefore, consideration of the microbiome and gut barrier integrity with regard to psychometric and biochemical parameters could be important to support psychiatric disorders, including depression.
Abstract
BACKGROUND Interactions between the digestive system and the brain functions have become in recent years an important field of psychiatric research. These multidirectional interactions take place in the so called microbiota-gut-brain axis and emerging scientific data indicate to the significant role of microbiota in the modulation of the central nervous system (CNS) including affective and cognitive functions. OBJECTIVE An assessment of psychobiotic and immunomodulatory effects of probiotic bacteria Lactobacillus Plantarum 299v (LP299v) by measuring affective, cognitive functions and biochemical parameters in patients with MDD undergoing treatment with selective serotonin reuptake inhibitors (SSRI). DESIGN Seventy nine patients with MDD were randomized and allocated to a double-blind, placebo-controlled trial. Participants received either a SSRI with the probiotic LP299v (n = 40) for a period of 8 weeks or a SSRI with the placebo of the probiotic (n = 39) for the same period. The severity of psychiatric symptoms was assessed using Hamilton Depression Rating Scale (HAM-D 17), Symptom Checklist (SCL-90) and Perceived Stress Scale (PSS-10). Cognitive functions were assessed using the Attention and Perceptivity Test (APT), Stroop Test parts A and B, Ruff Figural Fluency Test (RFFT), Trail Making Test (TMT) Parts A and B and the California Verbal Learning Test (CVLT). Biochemical parameters such as tryptophan (TRP), kynurenine (KYN), kynurenic acid (KYNA), 3-hydroxykynurenine (3HKYN), anthranilic acid (AA), 3-hydroxy anthranilic acid (3HAA), tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL-6), interleukin 1-beta (IL-1b) and cortisol plasma concentrations were measured. RESULTS Sixty participants finished the study and were analyzed: 30 participants in the LP299v group and 30 participants in the placebo group. There was an improvement in APT and in CVLT total recall of trials 1-5 in the LP299v group compared with the placebo between baseline and after 8 weeks of intervention. There was a significant decrease in KYN concentration in the LP299v group compared to the placebo group. We also observed significant increase in 3HKYN:KYN ratio in the LP299v group compared with the placebo group. Additionally, Repeated Measures ANOVA revealed a significant effect of interaction of Treatment x time for AA concentration. However, results of post hoc analysis did not reach statistical significance in neither probiotic nor placebo group. There were no significant changes of TNF-α, IL-6 and IL-1b and cortisol concentrations in neither probiotic nor placebo groups. CONCLUSIONS Augmentation of SSRI treatment with probiotic bacteria Lactobacillus Plantarum 299v improved cognitive performance and decreased KYN concentration in MDD patients. Decreased KYN concentration could contribute to the improvement of cognitive functions in the LP299v group compared to the placebo group. To our knowledge results of this study are the first evidence of improvement of cognitive functions in MDD patients due to probiotic bacteria and this is the first evidence of decreased KYN concentration in MDD patients due to probiotic bacteria.

Plain language summary
Obesity is a chronic disease caused mostly by an excessive supply of energy delivered with food in relation to energy expenditure, which leads to fat accumulation. The aim of the study was to investigate the leptin/ghrelin ratio (appetite-regulating hormones) in response to meal intake with various macronutrient contents, and to assess the fasting and postprandial (after meal) differences between normal and overweight or obese men. The study is a crossover designed study which was conducted among 46 non-diabetic men. The participants were randomly divided into two groups. Each group included men with normal weight and overweight/obesity. Results indicate that in normal body weight men, a more beneficial leptin/ghrelin ratio was noted after the high-carbohydrate fat-free meal intake, compared to the normal-carbohydrate/high-protein and high-fat/low-carbohydrate meal. Furthermore, overweight/obese men presented with a significantly higher leptin/ghrelin ratio in a fasting state and after intake of each of the three meals. Authors conclude that overweight/obese individuals can be recommended to chose meals with lower carbohydrate content.
Abstract
BACKGROUND Hormones, which influence satiety and hunger, play a significant role in body energy balance regulation. Ghrelin is a peptide that plays an important role in short-term appetite regulation, whereas leptin is a factor that controls long-term energy balance and is considered as a satiety hormone. The aim of this study was to evaluate the leptin/ghrelin ratio in a fasting state and after the intake of meals with varying macronutrient contents and to assess the possible differences between normal body weight and overweight/obese men. METHODS We examined 46 healthy adult men (23 with normal body weight and 23 overweight/obese) aged 21-58, who were divided into two groups. In the crossover study, participants received isocaloric (450 kcal) meals with different macronutrient contents: men from the first group received high-carbohydrate (HC) and normo-carbohydrate (NC) meals, and in the second group, participants received high-carbohydrate and high-fat (HF) meals. The ratio of leptin/ghrelin levels was calculated from leptin and total ghrelin serum concentrations in a fasting state and 30, 60, 120, 180 and 240 min after meal intake. One-way ANOVA and Wilcoxon signed-rank tests were carried out. The normality of the variable distribution was checked with the Shapiro-Wilk test, the homogeneity of variances was verified with the Levene test, and the false discovery rate p-value adjustment method was used. RESULTS The leptin/ghrelin ratio was significantly higher in overweight/obese men than individuals with normal body weight in a fasting state, as well as postprandially. We observed trends towards a higher leptin/ghrelin ratio values from the 60 min after HC-meal intake compared to the NC- and HF-meals in normal body weight participants, while in overweight/obese men, we did not note any significant differences dependent on the meal type. CONCLUSIONS We have observed a significantly different postprandial leptin/ghrelin ratio in normal body weight and overweight/obese men, and our results suggest that in men with normal body weight, a greater feeling of satiety may occur after high-carbohydrate meal intake, which was not noted in the overweight/obese individuals.

Abstract
INTRODUCTION Diet is one of the factors that can stimulate genetic predisposition and, in consequence, lead to insulin resistance. An adequate supply of nutrients and energy-rich diet as well as increased physical activity are the most effective methods to prevent metabolic disorders. OBJECTIVES The objective of this study was to determine whether there are any associations between nutrition and the occurrence of insulin resistance. PATIENTS AND METHODS The study included 143 individuals. Fasting glucose and insulin levels were measured and the HOMA-IR index was calculated for each patient. Nondiabetic patients were divided into the study and control groups. We conducted anthropometric measurements (body mass, height, and waist circumference), biochemical analysis (fasting glucose and insulin), and dietary interview. RESULTS We observed a negative correlation between the percentage of sucrose in the diet and the HOMA-IR value, and a positive correlation between the percentage of protein intake and the HOMA-IR value. Moreover, there was a significantly higher intake of lactose in men without insulin resistance compared with those with insulin resistance. CONCLUSIONS The results encourage to conduct further, more detailed research involving a larger group of patients to better understand associations between dietary content and insulin resistance.

Medycyna pracy. 1996;(5):461-5
Abstract
The aim of the study was to examine the relationship between the work load, evaluated by the occupational activity, and the incidence of cholelithiasis. In total 372 subjects (169 cholelithiasis patients examined using USG, and 203 controls), hospitalised in 1993 in the Department of Gastroenterology, Regional Hospital, Białystok, completed the questionnaire. Attention was also given to age, sex, permanent residence, education and physical activities after work. A moderate physical effort, both occupational and non-occupational, seemed to reduce the risk of cholelithasis.
