- Abstract
Introduction: Hemorrhoidal disease is the most common disease treated in proctology ambulatories. Conservative treatment is the basic form of treatment for this disease. One of the elements of treatment may be preparations with myoand phlebotropic effects. Aim: To assess the effect of a multi-ingredient myophlebotropic dietary supplement used as an adjunct on the rate and effectiveness of symptom relief in patients with stage II and III hemorrhoidal disease. Material and method: Patients with stage II and III hemorrhoidal disease with clinical symptoms such as pain, burning, itching and bleeding were qualified for the study. The patients were divided into two groups. The control group (Group I) of 29 patients receiving standard local treatment plus placebo and the study group (Group II) of 32 patients receiving the same local treatment and a six-component myophlebotropic product. Symptoms were analyzed at the time of inclusion in the study (day 0), after 4 and 10 days of therapy. The severity of hemorrhoidal disease and the feeling of relief were assessed on the day of inclusion (W0) and after 30 days of therapy. Results: There were no statistical differences between the groups in terms of disease advancement, age, gender, and duration of symptoms. Compared to the moment of inclusion in the study (W0), after 4 days (W1), after 10 days (W2) of taking the multi- -component product, there was a statistically significant improvement in the VAS scale: spontaneous pain and pain during defecation. In the qualitative assessment (yes/no), there were statistically significantly fewer cases of burning in the anus and itching. The treatment did not affect the rate of spontaneous bleeding, which was low at the beginning of the study, but significantly reduced the rate of bleeding during defecation. After 30 days of observation, it was found that the improvement in the severity of hemorrhoidal disease symptoms was significantly higher in the group using the tested preparation. Relief after a month of the study (one-question method) was noted in the group of patients receiving the tested product. Conclusions: The tested six-component myophlebotropic product proved to be effective in reducing the severity of symptoms such as spontaneous pain, pain during defecation, burning/burning in the anus and bleeding during defecation. Statistical significance was demonstrated in the symptom’s relief and reduction in the severity of hemorrhoidal disease. [ABSTRACT FROM AUTHOR]

In recent years, much has been written about the possibilities of using exogenous sodium butyrate in the prevention and treatment of gastrointestinal diseases, in prehabilitation, in peri- and postoperative treatment, as well as its local application. It became possible thanks to the development of a special formulation (microencapsulation technique) enabling the delivery of unstable butyrate compounds to the large intestine, where it is used primarily as a source of energy. It also plays a key role in maintaining body homeostasis by maintaining the integrity of the intestinal epithelium and stimulating the intestinal immune system. There is growing evidence of the effectiveness of sodium butyrate in various areas of health. The following article discusses the possibilities of using microencapsulated sodium butyrate in the prevention and treatment of gastrointestinal diseases from the perspective of a gastroenterologist and gastrointestinal surgeon.

- Abstract
Recently, special attention has been paid to the relationship between diet and inflammation in the body. A factor that influences both diet and inflammation is physical activity. The aim of this study was to assess the inflammatory potential of the diets of young people engaging in regular physical activity. The participants were physical education students (n = 141 men and n = 151 women). The measurements included basic anthropometric parameters and a 4-day nutritional history from which the dietary inflammatory index (DII) was calculated. The average DII for female students was 2.09 ± 1.52, and that for male students was 0.21 ± 1.69. Consumption of all macro- and micronutrients was significantly higher among women and men with the lowest DII value (corresponding to an anti-inflammatory diet). The female and male students consuming anti-inflammatory diets were characterized by greater lean body mass (LBM), and, for the male students, a lower body fat content, compared to those whose diets were pro-inflammatory. Young and regularly physically active people are also exposed to the pro-inflammatory nature of their diets, whose long-term effects may lead to health problems. [ABSTRACT FROM AUTHOR]

The article titled "Ambiguous Faces of Water-Based Inclusion Compounds: L4(4)8(8) Intercalato-Clathrate Hydrate of Pt(II) Complex" explores the crystal structure of a PtII complex and its water layers that encapsulate guest molecules. The formation of these layers is driven by hydrophobic hydration and influenced by the size of the solute. The researchers compare this compound to similar water-based inclusion compounds to suggest parameters that characterize the corrugation of individual layers. The article provides more detailed information on this research and can be found in Chemistry - A European Journal. [Extracted from the article]

- Abstract
Topologies of ladder packing arrangements in crystal structures of five azaheterocyclic phosphonates were characterized by four geometrical descriptors introduced in the paper. The structural analysis was augmented by detailed calculations on interactions stabilizing the molecular assemblies. Intermolecular energies were evaluated using PIXEL and DFT(M062x-GD3) methods. Additionally, fingerprint plots derived from the Hirshfeld surfaces were generated for each structure to characterize the crystal packing arrangement in detail. All structures are stabilized by the relatively weak hydrogen bonds and nonbonding interactions involving aromatic rings, i.e., π···π, C–H···π, and (lp)···π effects. Distribution of the molecular electrostatic potential demonstrates that positively charged, endocyclic sulfur atoms are prone to chalcogen–chalcogen (S···O) bonding. Analysis of the supramolecular motifs shows the lack of a common synthon responsible for the ladder packing arrangements. However, the striking geometry similarity of all molecules indicates that ladder packing is based on a shape oriented molecular recognition and mostly driven by the van der Waals forces. The intermolecular electrostatic effects are crucial for stabilizing and fixing geometry of the already formed molecular clusters.

- Abstract
Clathrate hydrates are among the most intensively studied H-bond inclusion compounds. Despite the broad definition for this class of compounds, their meaning commonly refers to closed polyhedral nanocages that encapsulate small guest molecules. On the other hand, larger solutes enforce another type of encapsulation because of the solute size effect. Herein, we report a series of structures containing various molecules encapsulated by intercalated water layers constructed of polycyclic moieties of L4(4)8(8) topology. We parametrized the corrugation of individual layers and characterized interactions governing their formation. We suggested that these could be categorized as two-dimensional clathrates based on the character of intra-layer interactions and the effects observed between entrapped molecules and water-based intercalators., (© 2024 Wiley-VCH GmbH.)

- Abstract
Background/aims: Patients with diverticular disease (DD) frequently have abnormal bowel movements. However, it is unknown whether the entity of these alterations is associated with the severity of DD. We aimed to assess bowel habits and their relationship with the severity of DD according to Diverticular Inflammation and Complication Assessment (DICA) classification, Combined Overview on Diverticular Assessment (CODA) score, and fecal calprotectin (FC)., Methods: An international, multicenter, prospective cohort study was conducted in 43 centers. A 10-point visual analog scale (VAS) was used to assess the severity of constipation and diarrhea. The association of constipation and diarrhea with DICA classification, CODA score, and basal FC was tested using non-parametric tests. Survival methods for censored observations were applied to test the association of constipation and diarrhea with the incidence of acute diverticulitis over a 3-year follow-up., Results: Of 871 patients with DD were included in the study. Of these, 208 (23.9%) and 199 (22.9%) reported a VAS score for constipation and diarrhea at least 3 at baseline, respectively. Higher constipation and diarrhea scores were associated with increasing DICA classification, CODA score and basal FC (P< 0.001). Constipation and diarrhea scores were independently associated with an increased hazard of developing acute diverticulitis (hazard ratio [HR]constipation = 1.15 per 1-VAS point increase, 95% confidence interval [CI], 1.04-1.27; P=0.004; and HRdiarrhea =1.14; 95% CI, 1.03-1.26; P=0.014, respectively)., Conclusions: In newly diagnosed patients with DD, higher endoscopic and combined scores of DD severity were associated with higher scores of constipation and diarrhea at baseline. Both constipation and diarrhea were independent prognostic factors of acute diverticulitis.
