Background/Objectives: Irritable bowel syndrome (IBS) is a common disorder of brain–gut interaction characterized by abdominal pain and altered bowel habits. While stress and anxiety are known to exacerbate IBS symptoms, less is understood about how these factors interact on a daily timescale. This study aimed to clarify the relationship between daily stress and abdominal pain in IBS and to examine whether trait anxiety moderates this association. Methods: Forty-nine IBS patients completed daily assessments of stress and abdominal pain over a 14-day period. Participants rated abdominal pain three times daily and reported daily stress levels across seven life domains each evening. Trait anxiety was assessed at baseline using the STAI-T. Results: Hierarchical linear modeling was used to analyze within-person and between-person effects. An increase in between-person stress was associated with increased probability of abdominal pain among individuals with low-to-moderate trait anxiety, while this was not observed in patients with high trait anxiety. Even though within-person (day-to-day) stress variations had an impact on pain probability, the effects of between-person variations were multiple times greater. Conclusions: These findings suggest that the interplay between stress and anxiety in IBS might not be uniform. High trait anxiety may, under certain conditions, attenuate rather than amplify the link between stress and pain, possibly pointing to a more dynamic relationship. Full article

Background/Objectives: An increasing number of apparently healthy individuals are adhering to a gluten-free lifestyle without any underlying medical indications, although the evidence for the health benefits in these individuals remains unclear. Although it has already been shown that a low- or gluten-free diet alters the gut microbiota, few studies have examined the effects of this diet on healthy subjects. Therefore, our aim was to evaluate whether and how a prolonged low-gluten diet impacts gut microbiota composition and function in healthy adults, bearing in mind its intimate link to the host’s health. Methods: Forty healthy volunteers habitually consuming a gluten-containing diet (HGD, high-gluten diet) were included in a randomised control trial consisting of two successive 8-week dietary intervention periods on a low-gluten diet (LGD). After each 8-week period, gut microbiota composition was assessed by 16S rRNA gene sequencing, molecular quantification by qPCR, and a cultural approach, while its metabolic capacity was evaluated through measuring faecal fermentative metabolites by ¹H NMR. Results: A prolonged period of LGD for 16 weeks reduced gut microbiota richness and decreased the relative abundance of bacterial species with previously reported potential health benefits such as Akkermansia muciniphila and Bifidobacterium sp. A decrease in certain plant cell wall polysaccharide-degrading species was also observed. While there was no major modification affecting the main short-chain fatty acid profiles, the concentration of the intermediate metabolite, ethanol, was increased in faecal samples. Conclusions: A 16-week LGD significantly altered both composition and metabolic production of the gut microbiota in healthy individuals, towards a more dysbiotic profile previously linked to adverse effects on the host’s health. Therefore, the evaluation of longer-term LDG would consolidate these results and enable a more in-depth examination of its impact on the host’s physiology, immunity, and metabolism. Full article

The aim of this study was to evaluate structural and micro-architectural changes in the mandible, parietal bone, femur, and tibia in OVX rats at different time periods after ovariectomy. Forty-two 11-month-old female Wistar rats were used. Six rats without surgery were euthanized to serve as a baseline. Eighteen rats were ovariectomized and fed with a calcium-deficient diet, and eighteen animals were used as controls (Ctrls) and fed with a standard diet. Six OVX rats and six Ctrls were euthanized at 3, 6, and 9 months. Qualitative histology and dual-energy X-ray absorptiometry (DXA) were performed. Histological evaluation of bones harvested from the OVX groups revealed trabecular bone reduction, while no significant differences in the cortical bone of OVX and Ctrls were observed. DXA measurements of (1) femoral diaphysis showed a significant decrease in the OVX group compared to the Ctrl groups at 3 (p = 0.041), 6 (p < 0.001), and 9 months (p < 0.001); (2) the proximal tibia showed a significant decrease in the OVX group compared to the Ctrl groups (p < 0.001); (3) parietal bone showed a significant difference between OVX and Ctrls at 6 months (p = 0.012); and (4) the mandible showed no significant differences between the OVX and Ctrl groups. OVX aged rats might present reductions in the density of the femoral diaphysis, proximal tibia, parietal bone, and mandible at different time points. These findings contribute to the field of biomimetics by providing more details for the understanding of age- and hormone-related bone changes in the osteoporotic-like rat model. Such data are critical for the development of biomimetic materials and structures that attempt to simulate natural bone adaptation and deterioration, especially in the context of postmenopausal or osteoporotic conditions.

Background/Objectives: Cooling strategies are critical for optimizing athlete recovery and performance in team sports, yet practical, accessible solutions remain underexplored. This study evaluated the efficacy of a cool vest during a 15 min recovery period following 45 min of simulated soccer match play on core and skin temperature regulation. Methods: Forty-seven physically active males completed an exercise protocol replicating the physiological demands of a soccer half-match. Participants were randomized into an experimental group using a cool vest during recovery (IG, n = 24) or a control group (CG, n = 23) without cooling intervention. Results: Compared to CG, IG exhibited small but significant reductions in skin temperature (31.46 ± 0.67 °C vs. 32.40 ± 1.04 °C; ES = −0.24, 95% CI: −0.40 to −0.08; p = 0.003) and tympanic temperature (35.99 ± 0.45 °C vs. 36.54 ± 0.66 °C; ES = −0.43, 95% CI: −0.67 to −0.18; p < 0.001) 10 min post-exercise. These differences intensified to small and moderate effects at 15 min post-exercise for skin (31.07 ± 0.67 °C vs. 32.51 ± 0.91 °C; ES = −0.37, 95% CI: −0.53 to −0.21; p < 0.001) and tympanic temperatures (35.70 ± 0.42 °C vs. 36.65 ± 0.58 °C; ES = −0.71, 95% CI: −0.96 to −0.46; p < 0.001), respectively, with IG maintaining consistently lower values. No temperature changes were observed in CG. Conclusions: These findings demonstrate that a 15 min cool vest application during halftime effectively reduces core and skin temperatures, compared to passive recovery. This supports its utility as a practical, low-cost strategy for thermoregulatory management in soccer, warranting further investigation into its long-term performance benefits. Full article

Tetanus is a life-threatening, vaccine-preventable disease caused by tetanospasmin and tetanolysin, which are potent neurotoxins produced by Clostridium tetani, an anaerobic, spore-forming bacterium. Due to the widespread presence of spores in the environment, the disease cannot be eradicated. However, global tetanus prevention initiatives have contributed to a significant decline in tetanus incidence worldwide. Aiming to present the tetanus trends in Romania, we conducted a retrospective analysis of the tetanus surveillance data. During the study period (2010–2023), 97 cases of tetanus were reported in Romania (median: 6.5; IQR: 5–7) with an average incidence rate of 0.03 per 100,000 inhabitants (95% CI: 0.02–0.04; range: 0.01–0.09). The highest incidence rates were recorded among people aged 1 to 14 years old (0.09 per 100,000 inhabitants, 95% CI: 0.06–0.13; range: 0.00–0.20), male (0.05 per 100,000 inhabitants; 95% CI: 0.03–0.06; range: 0.03–0.12), and from rural areas (0.05 per 100,000 inhabitants; 95% CI: 0.03–0.08; range: 0.01–0.17). A decline in the number of tetanus cases of 7% by year was observed, which is supported by the statistical analysis showing a p-value of 0.005 (IRR: 0.93; 95% CI: 0.88–0.98). However, the same decline in tetanus incidence was not supported by the statistical analysis (IRR: 0.93; 95% CI: 0.44–1.98; p = 0.9). Forty-seven tetanus deaths were recorded, with an average case fatality ratio of 42% (95% CI: 25.62–57.92; range: 0–100), showing a decreasing trend of 9% by year (IRR: 0.91; 95% CI: 0.89–0.93). Although the annual number of tetanus cases in Romania has shown a slight downwards trend, its situation has remained relatively stable, as shown by the tetanus incidence. Moreover, the case fatality rate continues to be high. Therefore, our study emphasizes the importance of achieving high vaccination uptake among children and adolescents, raising awareness of the importance of booster doses in adults, and improving the management of tetanus-prone wounds.

Background: Dyspeptic symptoms are very common in the general population, with an estimated prevalence of 14% to 41%, and the majority of patients experience symptoms without an organic cause for them (so-called functional dyspepsia). While the pathophysiology of functional dyspepsia remains elusive, the impact of functional dyspepsia on quality of life is detrimental. The treatment involves a change in lifestyle—a healthy diet and physical activity—in combination with pharmacological treatments. However, currently, there is no standard therapy for this condition, although a nutritional approach appears to be feasible and well accepted by patients. In this context, the intake of some mineral water types might be able to play an important role. Objective: The aim of the present study was to evaluate whether the regular intake of bicarbonate natural mineral water (Aqua Carpatica from source “F2 Păltiniș”) is able to positively influence the symptomatic process of dyspepsia, promoting digestion and improving the quality of life of patients. Methods: The patients enrolled in this open-label study had diagnosis of functional dyspepsia formulated in accordance with the Rome III criteria. During the 4-week study, patients had to ingest tap water at 1.5 L/day (wash-out period: 2 weeks), and in the 2-week subsequent period, they had to ingest alkaline natural mineral water at 1.5 L/day. The primary efficacy endpoint of this study includes a statistically significant improvement (p < 0.05) in the “heartburn”, “regurgitation”, and “dyspepsia” subscales and the total Reflux Disease Questionnaire’s (RDQ) score with respect to the effects of alkaline natural mineral water. As secondary endpoints, we considered statistically significant improvements (p < 0.05) in quality-of-life scores (Psychological General Well-Being Index—Short form; PGWB-S), the patient’s self-assessment of the state of efficiency of their digestion, and their sense of post-prandial fullness, as well as the use of antacids. Results: Forty-five patients were enrolled: all were Caucasian and mostly women (25, 55.6% vs. 20 men, 44.4%), and they were aged between 25 and 75 years (50.6 ± 13.5 years; mean ± SD). The results of this preliminary study show a significant improvement in functional dyspepsia symptoms—as assessed via the RDQ—and an improvement in quality of life—as assessed using the PGWB-S score—after the intake of alkaline natural mineral water. Conclusions: This preliminary study provides clinical evidence for a recommendation of alkaline natural mineral water as a symptomatic treatment of dyspepsia. Full article

Hypocalcemia is common in dairy cows within the first 72 h post-calving, and can be either clinical or subclinical. Early detection is critical, but traditional laboratory tests are time-consuming and cow-side tests remain costly. A classic symptom of hypocalcemia is reduced ear skin temperature, which has been explored as a diagnostic tool in a previous study, but was not recommended at the end. Additionally, ambient temperature was found to strongly influence ear skin temperature, complicating diagnosis. The present study investigates infrared thermography of the ear as a potential non-invasive method for helping in the detection of hypocalcemia in Holstein cows. In order to differ from the previous study, with the goal of improving diagnosis accuracy, this research analyzed the entire ear temperature using infrared imaging software. Ambient temperature was factored in by categorizing samples into two groups based on air temperature: colder (−1.6 to 14.6 °C) and hotter (15.3 to 31.2 °C). Forty-two cows were monitored during the perinatal period, with blood samples and thermographic images taken twice a day until 48 h after calving. This study found that the median surface temperature of the ear correlated strongly with environmental temperature (r = 0.806, p < 0.001) and weakly with blood ionized calcium levels (r = 0.310, p < 0.01). In colder air temperatures, ear surface temperature was significantly different between healthy and hypocalcemic cows (p = 0.014). Logistic regression models were used to assess ionized calcium status based on different combinations of ear surface temperature, its difference from air temperature, and days in milk. In hotter air temperatures, only ear surface temperature, with no other covariates, was able to generate a valid model (p = 0.029). In colder air temperatures, multiple combinations of those variables generated valid models (p < 0.05), with the difference between ear and air temperature, together with days in milk, performing the best. Thus, this study concluded that ear surface temperature obtained through infrared thermography, while not promising for warmer environments, does show application potential for helping in the detection of hypocalcemia in colder environments.

Objectives: To evaluate and compare the plaque-reducing efficacy of sesame-based oil pulling versus distilled water in a randomized controlled, examiner-blinded parallel-group study. Materials and Methods: Forty participants with gingivitis (community periodontal index of treatment needs grade 1 or 2) were randomly assigned to either the test group (sesame-based oil) or the control group (distilled water). Participants were instructed to perform oil pulling daily in the morning for 15 min over an eight-week period. The Rustogi Modified Navy Plaque Index (RMNPI) and gingival bleeding index (GBI) were evaluated at the baseline, as well as after four and eight weeks. Additionally, biofilm samples were collected for microbiological analysis. Results: The RMNPI was statistically significantly reduced after eight weeks of pulling with sesame-based oil (p < 0.001), as well as with distilled water (p < 0.001), without a significant difference between the groups. The GBI was statistically significantly reduced after eight weeks of pulling with sesame-based oil (p < 0.002), as well as with distilled water (p < 0.002), without a significant difference between the groups. No significant microbiological changes were detected in biofilm samples. Conclusions: Both plaque and gingival indices significantly decreased with oil pulling after eight weeks of intervention. Preclinical studies are necessary to clarify the mechanism of plaque reduction by oil pulling. Full article

Objectives: Identification of monosodium urate (MSU) and calcium pyrophosphate (CPP) crystals in synovial fluid should ideally be performed within 24 h to ensure optimal diagnostic accuracy for gout and CPP arthritis. However, crystal identification is often delayed in community-based healthcare facilities due to limited access to specialists or necessary equipment. This study aimed to determine whether MSU and CPP crystals remain detectable in synovial fluid after two weeks of storage at 4 °C and −20 °C. Methods: Anonymized synovial fluid samples were obtained from Thammasat University Hospital between February and March 2024. All samples underwent an initial round of crystal identification using compensated polarized light microscopy, conducted by two experienced examiners blinded to the clinical diagnosis. Following the initial analysis, each sample was divided into two equal portions and placed in ethylenediaminetetraacetic acid (EDTA)-coated tubes. One portion was stored at 4 °C, while the other was frozen at −20 °C. After two weeks, all samples underwent a second round of crystal identification. Results: Forty-nine samples were included for the first evaluation; MSU and CPP crystals were identified in 14 and 6 samples, respectively. On the second examination, MSU crystals were detectable in 13/14 (92.8%) samples stored at 4 °C and 12/14 (85.7%) samples stored at −20 °C. However, CPP crystals were detectable in 2/6 (33.3%) samples stored at both temperatures. No new crystal formation in initially negative samples was observed. Conclusion: MSU crystals remain detectable in synovial fluid for up to two weeks when stored in a standard refrigerator or freezer. However, the identification rate of CPP crystals tends to decline over this period. These findings may help inform best practices for handling synovial fluid samples in cases where immediate access to a specialist or necessary equipment is unavailable. Full article

Training individualisation is a key principle for maximising improvements in players’ performance, but there are still few approaches to individualisation of training in basketball players. The aims of this study were as follows: (I) to analyse the effects of two individualised training approaches on performance in male basketball players; (II) to compare the inter-individual differences in adaptations of these physical abilities; and (III) to assess differences in physical performance between two time periods of training intervention. Forty-five male basketball players (age, 22.3 ± 4.18 years; body height, 1.86 ± 0.15 m; body mass, 86.3 ± 7.85 kg) were divided into three groups: a vertical group (n = 15), who performed an individualised training programme based on a force–velocity profile; a horizontal group (n = 15), who underwent individualised intervention based on change of direction deficit; and a control group (n = 15). The assessments included jump and speed tests. Strength training was administered twice weekly for 8 weeks. Both intervention groups demonstrated large significant group x time interactions in jump (η_p² ≥ 0.24, p < 0.01) and speed (η_p² = 0.23, p < 0.01), with no significant changes in the control. The largest performance gains were achieved in the specific force orientation targeted by each intervention. These findings suggest that addressing the individual needs of each player and the specificity of the physical ability are key considerations for training programming in basketball players.

Background and Objectives: The worldwide prevalence of chronic kidney disease (CKD) continues to increase, representing a major concern for public health systems. CKD is associated with gut microbiota dysbiosis, which may exacerbate disease progression by increasing the levels of uremic toxins, systemic inflammation, and oxidative stress. Modulation of the gut microbiota through biotic supplementation has been proposed as a potential therapeutic strategy to slow CKD progression and mitigate its complications. This study aimed to evaluate the effect of 10-month synbiotic supplementation on estimated glomerular filtration rate (eGFR), circulating concentrations of indoxyl sulfate (IS), p-cresyl sulfate (p-CS), interleukin-6 (IL-6), and malondialdehyde (MDA) in patients with stage IV–V CKD not receiving dialysis, in comparison to placebo. Materials and Methods: Fifty non-dialysis CKD IV–V patients were assigned (n = 25 each) via matched, non-randomized allocation (age, sex, and primary disease) to synbiotic or placebo. This single-blind, placebo-controlled trial blinded participants and laboratory personnel. The synbiotic group received daily capsules containing Lactobacillus acidophilus La-14 (2 × 10¹¹ CFU/g) + fructooligosaccharides; controls received identical placebo. Adherence was monitored monthly (pill counts, diaries), with < 80% over two visits resulting in withdrawal. The eGFR, IS, p-CS, IL-6, and MDA were measured at baseline and month 10. Results: Forty-two patients (21/arm) completed the study; eight withdrew (4 per arm). At 10 months, the change in eGFR was −1.2 ± 2.5 mL/min/1.73 m² (synbiotic) vs. −3.5 ± 3.0 mL/min/1.73 m² (placebo); between-group difference in change was 2.3 mL/min/1.73 m² (95% CI: 0.5–4.1; p = 0.014; adjusted p = 0.07). IS decreased by −15.4 ± 8.2 ng/L vs. −3.1 ± 6.5 ng/L; between-group difference in change was −12.3 ng/L (95% CI: −17.8 to −6.8; p < 0.001; adjusted p = 0.005). No significant differences were observed for p-CS, IL-6, or MDA after correction. Conclusions: Synbiotic supplementation over a 10-month period resulted in a trend toward decreased serum IS levels in patients with advanced CKD, suggesting potential benefits of microbiota-targeted therapies. However, no significant effects were observed on renal function, inflammatory, or oxidative stress markers. Further large-scale studies are warranted to confirm these findings and explore the long-term impact of synbiotics in CKD management. Full article

This study aimed to determine the prevalence of type 1 diabetes mellitus (T1DM) in French Guiana and describe the social profiles of the patients. We conducted a multicenter cross-sectional study of children under 18 years who were diagnosed with type 1 diabetes and followed up from 2002 to 2021. Over a 20-year period, 48 children under 18 years with type 1 diabetes living in French Guiana were included in the study, out of a total of 59 cases. There were 26 girls and 22 boys. The median age at diagnosis was 8.52 years [IQR 6–12]. The incidence rate was 5.9 per 100,000 people in children aged 0–18 years. The 5–9-year age group was the most affected 43.7% (95% CI 38–51%). Of these children, 56.2% (95% confidence interval 40–70%) lived in single-parent households, and 35% (95% CI 23–57%) of the parents had a primary education. Of the children, 29% (95% CI 21–42%) were from families with no resources. Diabetes was diagnosed by ketoacidosis in 56% (95% CI 38–74%) of the patients. Forty percent (95% CI 35–66%) of the patients had an HbA1c > 9%. There was an imbalance in the prevalence of children with higher Hba1c (>9%), with 18.7% (95% CI 10–29%, p < 0.001) of children whose parents had a low level of education having an Hba1c > 9% compared with only 6% (95% CI 3–10%) of children whose parents had a university degree, and a marked imbalance in the prevalence of children with High Hba1c (>9%) among children from single-parent families (22.9%, 95% CI 17–30%) compared with children whose parents lived in couples (8%, 95% CI 5–12%). The 10–14-year age group (18.7%, 95% CI 11–25%) had the highest imbalance in the prevalence of poor diabetes control between children whose parents had lower versus higher education levels. Diabetic retinopathy and diabetic nephropathy were the only reported complications. The multivariate analysis showed that a low level of parental education (Odds ratio 2.9 [95% CI 2.1–4.5], p < 0.001) and single-parent families (Odds ratio 3.1 [95% CI 2.6–4.3], p < 0.001) were predictors of poor control of T1DM. However, the lack of social insurance coverage at diagnosis was not associated with poor T1DM control (p = 0.4). In conclusion, these sociodemographic factors should be considered when caring for children with T1DM in French Guiana. Full article

Background/Objectives: There is limited data on well-documented comorbidities with polysomnography (PSG)/multiple sleep latency test (MSLT) findings in idiopathic hypersomnia (IH). We aimed to characterize the clinical, PSG/MSLT characteristics of IH patients in our health network. Methods: We reviewed charts of all IH cases between 2000 and 2023, extracting clinical features, comorbidities, and PSG/MSLT findings. Results: One hundred forty-two patients (83.80% female) with IH were included. Compared to those without mood disorders, both major depressive disorder (MDD) and anxiety patients were older at onset (27.10 ± 8.32 and 26.76 ± 8.40 versus 23.23 ± 6.94 and 24.05 ± 7.31 years; p = 0.003 and p = 0.042) and had lower ESS (15 versus 19; 15.67 versus 17.75; p < 0.0001), more disrupted sleep (28 (36.36%) versus 8 (12.31%); p = 0.001; 24 (35.82%) versus 12 (16%); p = 0.007), and less sleep inertia (30 (38.96%) versus 38 (58.46%); p = 0.021; 26 (38.81%) versus 42 (56%); p = 0.04). Fifteen patients with dysautonomia disorders presented at an earlier age (21.80 ± 6.60 versus 25.75 ± 8, p = 0.0682). On MSLT, MDD, anxiety, and dysautonomia patients had longer sleep latencies than the non-affected counterparts (6.40 (5.40–7.60) minutes versus 3.60 (2.60–5.40) min., <0.0001; 6.20 (5.20–7.40) versus 4 (2.60–6.40) minutes; p < 0.0001; 7.40 (6–7.80) versus 5.40 (3–7); p = 0.008). MDD and anxiety cases had fewer sleep onset REM periods (7 (9.09%) versus 16 (24.62%), p = 0.0124 and 6 (8.96%) versus 17 (22.67%), p = 0.0388) compared to those not affected by these disorders. Conclusions: Our study highlights the importance of recognizing mood disorders and dysautonomia in patients diagnosed with IH. Further research may elucidate management strategies for these patients.

The physiological capabilities of horses begin to decline after they reach 15 years of age. However, some exceptionally talented horses can continue their sports careers beyond this age, raising concerns about their welfare. This study investigated animal welfare by observing resting heart rate (HR) and heart rate variability (HRV) metrics in geriatric horses participating in similar training or physical activities compared to younger adult horses over 30 min periods. Forty-six horses of varying ages and activity levels were divided into four groups, including horses under 15 years practising structured training for dressage (AL-1; N = 13) and school riding (AL-2; N = 13) and horses aged between 15 and 20 years participating in AL-1 (N = 10) and AL-2 (N = 10). In adult horses, the HR decreased in those performing AL-1, which was observed alongside an increased RR interval compared to those participating in AL-2 (p < 0.05 for both). Meanwhile, HRV increased in adult horses (measured by pNN50) but decreased in geriatric horses (measured by SDANN, SDNNI, DC, and SD2) participating in AL-1 when compared to their counterparts in AL-2 (p < 0.05 for all). Adult horses exhibited better autonomic regulation while engaged in structured dressage training than geriatric horses. These findings underscore the necessity for the careful management of physical activities to ensure the well-being of all horses, particularly older ones. Full article

This study examines the short-term impact of an “eco-feedback” strategy, based on an awareness-raising information campaign and an experimental campaign, on indoor environmental quality (IEQ) parameters and sleep quality in Italian bedrooms. Forty-one participants from Cassino, Italy, monitored the IEQ in their bedroom environments during the winter and spring seasons and assessed their sleep quality using the Groningen Sleep Quality Scale before and after receiving awareness-raising information. The experimental analysis revealed that, even if the IEQ and self-reported sleep quality before receiving the information were not representative of good sleep conditions (e.g., 94% of the volunteers slept in bedrooms with a median indoor CO₂ concentration >800 ppm, the equivalent continuous sound pressure level was always >30 dB, and the self-reported sleep quality conditions were characteristic of disrupted sleep or intermediate sleep disturbance), the subjects were not able to obtain significant changes in IEQ parameters after the information campaign and that, consequently, no noticeable changes in sleep quality were obtained as well. The limited effectiveness of the eco-feedback strategy adopted in this study can be attributed to the fact that the proposed approach only led to behavioral changes characterized by a limited effect on the indoor environmental quality. This was mostly due to the period under investigation: as an example, the low nighttime outdoor temperatures did not allow for an improvement in the building ventilation during the night. Full article
