A previously unknown variant of the calcaneofibular ligament.

The lateral ankle joint is composed of three ligaments: the anterior talofibular ligament (ATFL), posterior talofibular ligament (PTFL) and calcaneofibular ligament (CFL). The ATFL and CFL demonstrate morphological variation, especially regarding their shape and number of bands. During standard anatomical dissection, an unusual type of triple CFL was observed: the CFL was composed of two bands originating on the lateral malleolus, and the presence of a lateral talocalcaneal ligament (LTC) originating on the talus bone. The insertion point of each band was located on the calcaneal bone. An understanding of these anatomical patterns provides a clearer view of ankle joint biomechanics, and improved the planning and performance of surgical treatment.

Nutritional Value and Physicochemical Properties of Male and Female Broad-Breasted Bronze Turkey Muscle.

Colored varieties of turkeys, such as the broad-breasted Bronze, not currently subject to intensive breeding work, are kept only in amateur breeding and treated rather as ornamental poultry. They are raised in extensive systems, which undoubtedly affects the quality of the meat obtained. Consumers are looking for meat with specific and unique sensory qualities; hence, the interest in meat from turkeys with a slower-than-typical growth rate, such as the broad-breasted Bronze, is justified. The object of this research was to analyze the physicochemical properties and nutritional value (amino acid, fatty acid, and antioxidant profile) of the breast and thigh muscles of broad-breasted Bronze turkeys with regard to gender. It was shown that gender had little effect on muscle chemical composition, amino acid, and fatty acid content (p > 0.05), as well as most oxido-reduction indices. However, significant differences were noted in muscle quality traits such as color brightness (L*; turkeys > indors; p = 0.023), proportion of red (a*; turkeys < indors; p = 0.048) and yellow (b*; turkeys > indors; p = 0.039), and water absorption (turkeys < indors; p = 0.009). The type of muscle also had a significant effect on quality characteristics. Higher a*, b*, C*, pH, water absorption, and thermal leakage were shown in the femoral muscle (p < 0.001), while L* and h were higher in the pectoral muscle (p < 0.001). Turkey meat was characterized by a high proportion of unsaturated fatty acids (MUFA + PUFA ~68%), favorable FA index values, and low lipid oxidation indices. Thigh muscles (especially turkey) were more caloric, and contained significantly (p < 0.001) more fat and all major FA groups. Breast muscles (especially of turkeys) were characterized by a high protein content (about 25%) and a high proportion of essential amino acids. The data obtained indicate that broad-breasted Bronze turkeys can provide high-quality meat, and are an excellent option for meeting modern consumer needs.

The assessment of bladder cancer resectability with bimanual palpation: A prospective study in laparoscopy and open cystectomy patients.

PURPOSE: To evaluate the value of examination under anesthesia (EUA) in the assessment of bladder resectability during cystectomy. MATERIALS AND METHODS: This prospective study included consecutive patients undergoing cystectomy for bladder cancer at a single center between June 2017 and October 2020. EUA was conducted before cystectomy by two urologists who assessed the bladder for limited mobility. One examiner was blinded to the imaging results. Soft tissue surgical margin status in the pathological evaluation of a cystectomy specimen served as a measure of resectability. We used multivariable logistic regression models to assess whether EUA performed by blinded or non-blinded examiners is associated with soft tissue positive surgical margins (PSMs) and to calculate the fraction of new information added by such an examination in addition to selected clinical variables. RESULTS: Among the 134 patients analyzed, limited bladder mobility was indicated by the blinded and non-blinded examiners in 23 (17.2%) and 21 (15.7%) cases, respectively. PSMs were identified in 22 (16.4%) patients, more often in patients with limited bladder mobility as assessed by the blinded (odds ratio [OR] 6.7; 95% confidence interval [CI], 1.9-24.2) and non-blinded examiners (OR 12.9; 95% CI, 2.9-57.5). The fraction of new information added by the blinded and non-blinded examiners was 48.6% and 57.7%, respectively. The enrichment of patients who underwent pure laparoscopic cystectomy (n = 102; 76%) and the inclusion of patients for emergent surgery may limit the generalizability of our findings. CONCLUSIONS: The identification of limited bladder mobility during preoperative EUA yielded prognostic information on surgical margin status. Our findings suggest that EUA has the potential to provide valuable insights in the assessment of bladder resectability. However, further research in a larger cohort of patients is warranted to validate and expand on these findings.

Should we be afraid of long-term cardiac consequences in children with multisystem inflammatory syndrome? Experience from subsequent waves of COVID-19.

The purpose of the study was to assess and compare short- and long-term cardiac complications of the multisystem inflammatory syndrome in children (MIS-C) by predominant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants throughout the pandemic. The analysis of prospectively collected data comparing cardiac complications of MIS-C during and after hospitalization across the original/alpha, delta, and omicron waves. Cardiac complications were defined as cardiac failure with systolic function impairment or hypotension or abnormalities in echocardiographic findings (decrease in LVEF, FS, valvular insufficiency, pericardial effusion, or coronary artery abnormalities). A total of 120 patients with MIS-C admitted to the Children's Hospital of Krakow between November 1, 2020, and May 5, 2023, were included in the study (74 during original/alpha dominance, 31 delta, and 15 omicron). Patients in the omicron group were found to be younger than those in the alpha and delta groups (37 vs. 75 vs. 80 months, p = 0.03). The frequency of cardiac failure with systolic function impairment or hypotension was diagnosed more frequently in the original/alpha and delta groups than in the omicron group (44.59% vs. 41.94% vs. 13.33%, p = 0.08) also echocardiographic abnormalities changed, with rates of 60.8%, 35.5%, and 13.3% (p < 0.001) accordingly. The multivariable regression revealed an older age (OR = 1.19, 95% CI = 1.07-1.33, p = 0.002) as the only independent factors of cardiac failure with systolic function impairment or hypotension. In all patients, signs of cardiac failure resolved during the hospitalization. Moreover, in 98.3% of patients, all echocardiagraphic abnormalities resolved completely during the observation period.    Conclusion: The cardiac complications of MIS-C appeared to advance less severely in younger children during the Omicron outbreak. In long-term observation, symptoms of cardiac failure resolve completely. Similarly, also echocardiographic abnormalities normalize in the vast majority of patients. What is Known: • Knowledge about the long-term cardiac complications of MIS-C is still evolving and uncertain. • The greatest concern of MIS-C is cardiac complications, including cardiac failure and coronary artery dilatation. What is New: • Long-term observations revealed complete resolution of cardiac complications in the vast majority of patients with MIS-C, irrespective of the dominant variant. • Cardiac complications of MIS-C were less common in younger children during subsequent pandemic waves in our patient population.

Nutritional and Antioxidative Benefits of Dietary Macroalgae Supplementation in Weaned Piglets.

This study explores the effects of dietary brown macroalgae (Ascophyllum nodosum) inclusion on digestibility and blood biochemical indices and redox markers in piglets fed diets with varying levels (0%, 0.6% and 1%) of macroalgae from 18 to 64 days of age. Macroalgae significantly influenced lipid profiles, reducing total cholesterol levels (quadratic contrast p = 0.001) and demonstrating an increase in high-density lipoprotein cholesterol levels, particularly with 1% macroalgae inclusion (linear contrast p < 0.001), with a decrease in low-density lipoprotein cholesterol in both macroalgae-supplemented groups (linear contrast p = 0.001). Additionally, macroalgae had a positive impact on the activities of antioxidative enzymes (ferric-reducing ability of plasma, superoxide dismutase, reduced glutathione) and reduced lipid peroxidation products (lipid hydroperoxide, malondialdehyde) in the blood, liver tissue, and intestinal epithelium of the ileum, suggesting enhanced antioxidative defense mechanisms. These changes were dose-dependent; in blood plasma, they exhibited both a linear and quadratic response, while in the tissues, the response was primarily linear. Additionally, an increase in the digestibility of crude fat in macroalgae-supplemented groups was observed (linear contrast p < 0.001), highlighting their potential role in improving nutrient absorption and digestion. The study findings emphasize the health benefits of natural, seaweed-based additives in diets, particularly in managing oxidative stress and improving lipid profiles, and highlight the potential of macroalgae as a natural dietary supplement to improve antioxidant systems and lipid metabolism in piglets.

Sexual activity in a large representative cohort of Polish men: Frequency, number of partners, correlates, and quality of life.

INTRODUCTION: Sexual activity of men has been evaluated at the population-level in different regions of the world. However, reliable data are lacking for Eastern Europe. Therefore, the aim of this study was to analyze the frequency of sexual activity and the number of sexual partners in a large representative cohort of Polish men. METHODS: We performed a cross-sectional investigation with computer-assisted web interviews. Participants were stratified by age (≥18 years) and place of residence. The most recent population census was used to produce a population-representative sample of respondents. Men's sexual activity was then correlated with multiple variables. RESULTS: We enrolled 3001 men, representative for age and place of residence, including adequate proportions of respondents from urban and rural areas. Most Polish men were sexually active, predominantly having had sex at least weekly with one partner. Almost 18% of respondents declined sexual intercourse and/or sexual partner in the prior year. The highest sexual activity was observed for men 35-44-years-old (for sex frequency) and 18-24-years-old (for partner number), living in medium-sized cities, employed, and married (for sex frequency) or divorced (for partner number). Erectile dysfunction negatively affected the frequency of sexual activity and lowered the number of sexual partners, although premature ejaculation did not have any effect. Frequency of sexual activity and number of sexual partners correlated well with psychological distress, quality of sex life, and overall life quality. Whereas lifestyle habits including smoking and alcohol intake decreased the likelihood of sexual activity, all analyzed comorbidities did not affect sex life. CONCLUSIONS: This study of men's sexual activity was the first population-representative and nationwide investigation performed in Poland. Most Polish men were sexually active and sexual activity correlated with multiple variables including sociodemographic factors, erectile functioning, mental distress, overall and sex-specific quality of life, and lifestyle habits.

The effect of thyme herb in diets for fattening pigs on their growth performance and health.

To enrich pork with valuable n-3 PUFA, it is common practice to include flaxseeds in the swine diet. However, due to the high susceptibility of these acids to oxidation, this treatment requires an additional supply of antioxidants. Thyme herb can be used for this purpose, which in addition to high antioxidant activity is characterized by numerous health-promoting properties. The present study aimed at evaluating the impact of the inclusion of 1% and 3% of thyme herb in mixtures with 4% of extruded flaxseeds as a source of n-3 PUFA on the performance results and health status of fatteners. The experiment was carried out on 120 weaners with an initial body weight of about 30 kg and kept until the end of fattening. They were divided into three experimental groups of 40 animals each (5 pens with 8 pigs in each). The control group (C) consisted of pigs receiving a base mixture with 4% of extruded flaxseeds. In the experimental groups, an additional 1% (T1) or 3% (T3) of thyme herb was added to the mixture. By supplementing the diet with 3% of thyme, an increase in average daily weight gain (P = 0.001) and a better feed conversion ratio (P < 0.001) were obtained. This could be the result of an improvement in the small intestine histology (greater villus height-P < 0.001) and better digestibility of basic nutrients (especially crude protein-P < 0.05) found in experimental animals. In addition to these effects, thyme herb supplementation contributed to the stimulation of immune mechanisms (increase in the number of WBC-P ≤ 0.05; plasma IgA - P < 0.05 and IgG-P < 0.005, and the level of lysozyme-P < 0.05). The obtained results indicate the advisability of the use of thyme as a feed additive beneficially influencing the health and performance results in pigs. The obtained results indicate the advisability of the use of thyme as a feed additive beneficially influencing the health and performance results in pigs.

Effect of the inclusion of extruded flaxseed in the diet of fattening pigs on lipid metabolism and tissue redox status.

The aim of the study was to evaluate the effect of a diet containing extruded flaxseed (Linum usitatissimum L.) on the fatty acid composition of the loin, blood lipid parameters, and the redox status of tissues of finishing pigs. A total of 160 weaners (about 30-110 kg BW) were assigned to four experimental groups of 40 animals each (5 replicates with 8 individuals each). Group C (control) received a diet in which the fat source was soybean oil, while in groups 2FE, 4FE and 6FE soybean meal was replaced with extruded flaxseed in the amount of 2%, 4% or 6%, respectively. The diet containing extruded flaxseed reduced cholesterol levels in the blood plasma of pigs (grower 2FE and 6FE vs. C; finisher 2FE, 4FE and 6FE vs. C) and loin muscle (2FE, 4FE and 6FE vs. C). A decrease in the atherogenic LDL-C fraction and in the content of triacylglycerols was also noted in the blood plasma of grower and finisher pigs receiving flaxseed (2FE, 4FE and 6FE vs. C). The beneficial effects noted in the experimental pigs also included an increase in the overall content of n-3 PUFAs, especially ALA (18:3 n-3), and a reduction in the n-6/n-3 ratio. This was especially evident at 4% and 6% inclusion of flaxseed. The highest proportion of flax (6%) in the blend increased lipid peroxidation, as evidenced by the increase in the content of LOOH and MDA in the blood plasma of grower and finisher pigs. For this reason, a 4% share of flaxseed in the diet of fattening pigs seems to be optimal, while higher levels require an additional supply of exogenous antioxidants.

Effect of Thyme (Thymus vulgaris L.) Used in Diets with Extruded Flaxseed on the Antioxidant and Lipid Profile of the Blood and Tissues of Fattening Pigs.

Thyme has strong antioxidant properties and, therefore, can reduce the intensity of oxidative processes taking place in the body. The study aimed to assess whether the addition of thyme to diets for fattening pigs containing extruded flaxseeds, a source of n-3 PUFAs, which are particularly susceptible to oxidation, would have a positive effect on redox status and lipid metabolism. The experiment was conducted using 120 weaners (WBP × Neckar crosses) of about 30 kg BW, which were kept until the end of fattening (about 110 kg BW) and divided into three groups of 40 pigs. The control group received a diet with 4% extruded flaxseed. In groups T1 and T3, 1% or 3% of thyme was added to the basal diet. The introduction of 3% thyme resulted in a decrease in the total cholesterol level in the blood and the loin muscle. Moreover, an increase in SOD and CAT activity and a decrease in FRAP and LOOH was noted. Following supplementation with 3% thyme, the n-3 PUFA content and n-3/n-6 ratio increased, while the SFA content was significantly reduced. The results of the studies indicate that thyme has a positive effect on the redox status and lipid profile of the blood and muscles.

Diagnostic accuracy of bimanual palpation in bladder cancer patients undergoing cystectomy: A prospective study.

OBJECTIVES: To prospectively assess the concordance of examination under anesthesia (EUA)-based clinical T stage with pathological T stage and diagnostic accuracy of EUA in patients with bladder cancer undergoing cystectomy. METHODS: Consecutive patients with bladder cancer undergoing cystectomy between June 2017 and October 2020 in a single academic center were included in a prospective study. Two urologists performed EUA (one blinded to imaging) before patients underwent cystectomy. We assessed the concordance between clinical T stage in bimanual palpation (index test) and pathological T stage in cystectomy specimens (reference test). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated with 95% confidence intervals (CIs) to detect or exclude locally advanced bladder cancer (pT3b-T4b) in EUA. RESULTS: The data of 134 patients were analyzed. Given that stage pT3a cannot be palpated, for the nonblinded examiner, T staging in EUA was concordant with pT in 107 (79.9%) patients, 20 (14.9%) cases being understaged in EUA and 7 (5.2%) overstaged. For the blinded examiner, staging was correct in 106 (79.1%) patients, 20 (14.9%) cases being understaged and 8 (6%) overstaged. For the nonblinded examiner, sensitivity, specificity, PPV, and NPV of EUA were 55.9% (95% CI 39.2%-72.6%), 93% (88%-98%), 73.1% (56%-90.1%), and 86.1% (79.6%-92.6%), respectively; for the blinded examiner, they were 52.9% (36.2%-69.7%), 93% (88%-98%), 72% (54.4%-89.6%) and 85.3% (78.7%-92%), respectively. Awareness of imaging results did not have a major impact on EUA results. CONCLUSION: Bimanual palpation should still be used for clinical staging, given its specificity, NPV, and that it could correctly determine bladder cancer T stage in 80% of cases.

Effect of Fermented Rapeseed Meal in Feeds for Growing Piglets on Bone Morphological Traits, Mechanical Properties, and Bone Metabolism.

Quality feed is essential for correct bone development and proper functioning of animals. Post-weaned piglets experience a radical change in eating behaviour that can influence their feed intake. For this reason, functional feed additives and ingredients that can be used in post-weaning feeds are needed. The objective of this study was to evaluate the effects of partially replacing wheat with rapeseed meal fermented using Bacillus subtilis strain 87Y on overall bone quality and bone metabolism in weaner piglets. From the 28th day of life, barrows were fed either a standard wheat-based diet or a diet containing 8% fermented rapeseed meal (FRSM) with or without a feed additive containing enzymes, antioxidants, probiotics, and prebiotics. The experimental period lasted 60 days, after which femur quality indices were assessed. Differences in bone length and weight were observed, but there were no changes in bone mineralization or bone mid-diaphysis morphometrical traits between treatments. FRSM inclusion reduced bone mid-diaphysis biomechanical properties, but these changes were dependent on feed-additive supplementation. Analysis of the levels of serum bone turnover markers suggests the intensification of bone resorption in FRSM-fed groups as deoxypyridinoline levels increase. The results obtained warrant further research on what the disturbances in bone mechanical properties and metabolism observed in FRSM-fed weaners means for the subsequent fattening period.

Antioxidant status in the blood, liver, and muscle tissue of turkey hens receiving a diet with alfalfa protein concentrate.

This study aimed to investigate the impact of the oxidative potential of turkeys fed a diet with alfalfa protein concentrate (APC), used throughout the rearing period or periodically at 2-wk intervals. The research material consisted of 6-wk-old BIG 6 turkey hens kept in pens, 5 birds per pen in 6 replicates. The experimental factor was the addition of APC to the diet in the amount of 15 or 30 g/kg of diet. APC was administered in 2 ways: birds received a diet with APC throughout the experiment or periodically. In the latter case, the birds received the diet with APC for 2 wk, and then for 2 wk they received the standard diet without APC. Levels of nutrients in the diet; flavonoids, polyphenols, tannins, and saponins in APC; uric acid, creatinine, bilirubin, and some antioxidants in the blood; and enzyme parameters in the blood and tissues of turkeys were determined. The use of APC in the diet stimulated antioxidant processes, which could be seen in the values of the pro-oxidant-antioxidant parameters of the tissues and blood plasma of turkeys. The significant reduction in the H2O2 level (P = 0.042) and slight reduction in the MDA level (P = 0.083), accompanied by an increase in catalase (P = 0.046) activity in the turkeys continuously receiving APC in the amount of 30 g/kg of diet, as well as the increase in plasma antioxidant parameters (vitamin C, P = 0.042 and FRAP, P = 0.048) in these birds, reflects improvement in their antioxidant status. Thus continuous use of the APC supplement in the amount of 30 g/kg of diet proved to be a better feeding practice to optimize oxidative potential than periodic inclusion of APC.

Comparison of the course of multisystem inflammatory syndrome in children during different pandemic waves.

The purpose of this study is to assess the rate, clinical picture, and management of multisystem inflammatory syndrome in children (MIS-C) during the different COVID-19 variants of concern (VOC) domination periods. This was a retrospective analysis of prospectively collected data. The incidence and clinical picture of MIS-C during the original/Alpha (group 1) and Delta/Omicron (Group 2) variant domination periods were compared. Among 108 eligible patients, 74 (68.5%) were hospitalized during the group 1 domination period, and 34 (31.5%) were hospitalized during the group 2 domination period. The median (Me) patient ages were 76 months (interquartile range [IQR] 35-130) and 73 months (IQR 45-118), and 61% and 65% of patients were male, respectively. There was no significant difference in the presence of positive SARS-CoV 2 antibody test results (IgM or IgG) between the groups (84 vs. 90%; p = 0.54).No differences between groups were observed in fever duration prior to admission (Me [IQR]: 5 days [3-6] vs. 5 days [4-6]; p = 0.26) or the presence of mucocutaneous (95 vs. 100%; p = 0.41), circulatory (70.3 vs. 61.8%; p = 0.86), neurological (6.8 vs. 2.9%; p = 0.662), or gastrointestinal symptoms (84 vs. 79%; p = 0.59). Respiratory symptoms were more common in group 2 (70 vs. 91%; p = 0.015). The need for intensive care unit admission was similar in both groups (16.2 vs. 17.6%, p = 1.0). No deaths occurred in the entire cohort. The studied children were characterized by high C-reactive protein and procalcitonin levels, concentrations of ferritin within normal limits, lymphopenia, moderate hypoalbuminemia, and high B-type natriuretic peptide/brain natriuretic peptide (NT-proBNP) concentrations; however, there were no differences between the groups. Intravenous immunoglobulins were administered as a first-line treatment for almost all patients. There was no significant difference in corticosteroid administration between the groups (87% vs. 74%; p = 0.11); however, the summary dose of methylprednisolone was higher in group 2 (Me [IQR]″ 12.6 mg/kg [10.5-17.8] vs. 16.4 mg/kg [13.3-19.5]; p = 0.03). The median length of stay was 11 days [IQR]: [9-14] and 10 days [8-12], respectively (p = 0.065). CONCLUSION: The clinical course of MIS-C is similar in subsequent pandemic waves; however, the incidence of MIS-C seems to be decreasing. WHAT IS KNOWN: • The clinical picture of COVID-19 is evolving. Multisystem inflammatory syndrome in children (MIS-C) is a relatively new serious disease connected with SARS-CoV-2 infection, and in subsequent waves of the pandemic, new cases of the disease have been recorded. WHAT IS NEW: • The clinical picture of MIS-C is not specific, but the course is still severe. • The incidence of MIS-C during the different pandemic waves is decreasing and the diagnosis in the period of lower prevalance is challenging.

Investigation of structural and neurobiochemical differences in brains from high-performance and native hen breeds.

Selection of livestock has not only led to changes in the level of their performance but also modified their behavior. As a result, within a single species, we have to deal with different behaviors of different breeds. In our study, we assumed that the different behaviors within a species are due to differences in the morphology and physiology of behavior-related systems. Two breeds of hens were used as a model: the highly reactive, fearful and high-performance Leghorn breed and proactive, unselected Green-legged Partridge breed. The higher reactivity and fearfulness of Leghorn hens in comparison to the Green-legged Partridge breed may be related to the greater number of neurons in the paraventricular nucleus and anterior hypothalamus and the higher content of zinc and iron in the brain, as these elements are involved in neuronal conduction and myelination processes. The reactive behaviours of Green-legged Partridge hens may be associated with the lower number of neurons in the paraventricular nucleus and the anterior hypothalamus and the higher concentration of dopamine and copper ions in the brain. The analyses confirmed the hypothesis of the existence of interbreed differences in the morphology and physiology of behaviour-related systems, which most probably emerged through unintentional and correlated selection towards high production performance. Consequently, attention should be drawn that the selection of a given genotype (breed) towards a specific environment could lead to creation of highly specialised lines that may not achieve homeostasis in every maintenance system.

Sex Remains Negative Prognostic Factor in Contemporary Cohort of High-Risk Non-Muscle-Invasive Bladder Cancer.

Sex-specific differences in outcomes of patients diagnosed with high-risk non-muscle-invasive bladder cancer (HR-NMIBC) have been reported with controversial findings. This study aims to investigate sex-specific diversities in the treatment and oncologic outcomes of primary HR-NMIBC in a multicenter setting. A multicenter retrospective analysis of 519 patients (388 men and 131 women) treated with transurethral resection (TUR) for primary HR-NMIBC was performed. Univariable and multivariable Cox regression models were used to investigate the association of clinico-pathologic features and generate hazard ratios (HRs). Second-look TUR (reTUR) was performed in 406 (78%) patients. A total of 218 (42%) of patients were subjected to an induction course of intravesical BCG (Bacillus Calmette−Guérin) plus maintenance therapy. The median follow-up was 44 months. Among the entire cohort, 238 (46%) and 86 patients (17%) had recurred and progressed to muscle-invasive disease (MIBC), respectively. Female sex was associated with increased risk of disease recurrence in the entire cohort: HR = 1.94, 95% CI = 1.48−2.55, p < 0.001 and HR = 1.91, 95% CI = 1.39−2.60, p < 0.001 in univariate and multivariate analysis, respectively. In patients subjected to reTUR and treated additionally with BCG, female sex was associated with increased risk of disease recurrence in univariate analysis (HR 1.81, 95% CI 1.07−3.06, p = 0.03), but not in multivariate analysis (HR 1.99, 95% CI 0.98−4.02, p = 0.06). There was no difference between sexes with regard to disease progression. HR-NMIBC diagnosed in females is associated with higher risk of disease recurrence when compared to males.

Nutritional value and antioxidant capacity of organic and conventional vegetables of the genus Allium.

There are indications that organically grown plants are safer for health and have higher antioxidant content than conventional ones. Vegetables of the genus Allium L. are a valuable source of health-promoting substances, including compounds with antioxidant properties. The aim of the study was to compare the antioxidant potential and nutritional value of four species of Allium L. vegetables obtained from organic and conventional production: garlic, leek and red and yellow onion. Their proximate and mineral composition were determined, as well as the content of bioactive substances and antioxidant potential. The study showed that the cultivation method significantly influenced the parameters tested. Comparison of organic vegetables with conventional ones in terms of content of dry matter, crude protein and crude fibre revealed no general trend indicating the superiority of one method over the other. However, all organic vegetables analysed were more abundant in minerals (Ca, Mg, Fe, Zn, Cu and Mn) and bioactive compounds. They also exhibited higher antioxidant capacity as measured by the FRAP and DPPH. tests. Their consumption (especially organic garlic and leek) may therefore strengthen the body's natural antioxidant defences and is beneficial for health.

Effect of Fermented Rapeseed Meal in Diets for Piglets on Blood Biochemical Parameters and the Microbial Composition of the Feed and Faeces.

The study assessed the influence of rapeseed meal (RSM) fermented using Bacillus subtilis 87Y on the feed microbiota, intestinal microbiota, blood biochemical parameters, and content of minerals in the blood plasma and faeces of piglets. Modulation of the microbial composition of feed containing fermented rapeseed meal (FRSM) and of the faeces of pigs consuming it was observed. There was a significant increase in the number of lactic acid bacteria (LAB) and a decrease in the total number of coliforms and Clostridium perfringens in the faeces of animals from the experimental groups. FRSM in the diet of piglets was shown to improve the mineral balance by increasing the levels of P, Ca, and Mg in the blood plasma and reducing their amount in the faeces. A beneficial effect on parameters of protein and lipid metabolism was also noted, resulting in an increase in the levels of total protein (TP) and albumins (ALB) and a reduction in triacylglycerols (TG) and low-density lipoprotein (LDL) cholesterol in the blood plasma of the piglets. The research results indicate that the presence of FRSM in the diet of weaners can be a preventive factor in intestinal dysbiosis and support the maintenance of homeostasis.

Long-term functional outcomes of vesicourethral anastomosis with bladder neck preservation and distal urethral length preservation after videolaparoscopic radical prostatectomy.

Introduction: Radical prostatectomy (RP) is the standard surgical treatment for localized prostate cancer (PCa), with excellent oncologic outcomes; however, complications such as post-prostatectomy incontinence could significantly affect quality of life. Aim: To provide data on long-term urinary functional outcomes of bladder neck preservation (BNP) combined with distal urethral length preservation (DULP) in patients treated with videolaparoscopic prostatectomy. Material and methods: In this retrospective study, data were analysed from 619 consecutive patients who underwent laparoscopic radical prostatectomy (LRP) due to localized prostate cancer between November 2014 and December 2018 in a single tertiary care centre in Poland. Of these patients, 227 had BNP and DULP during the procedure. Urinary continence status was assessed in patients at 3, 6, 12, and 18 months after LRP. Cancer resection was assessed by surgical margin status. Results: In the group with BNP and DULP, urinary continence recurred earlier than it did in the control group up to 3 months after surgery: 204 (89.8%) patients in this group were fully continent compared with 283 (72.2%) in the control group (p < 0.001). The difference was also significant after 6 months (95.1% vs. 80.6%, respectively; p < 0.001). Despite these early promising results, there was no difference in urinary continence recovery after 12 and 18 months. There was also no difference between the 2 groups regarding surgical margin status of the resected tissue. Conclusions: Our study showed that BNP combined with DULP is a safe procedure that helps to improve early urinary continence rates after surgery without altering the risk of positive surgical margin.

Artificial urinary sphincter implantation with periprostatic cuff placement for urinary incontinence in men.

Introduction: Artificial urinary sphincter (AUS) implantation is the treatment of choice for male urinary incontinence (UI). The aim of the present study was to evaluate treatment outcomes of UI in men using an AUS with a cuff placed around the prostatic urethra. Material and methods: Forty-three men with preserved prostatic urethra were selected for AUS implantation due to UI. Twenty patients had the cuff implanted around the prostate using the retropubic approach (Group 1), and 23 had the cuff placed around the bulbous urethra (Group 2). Both groups were compared in terms of continence quality as well as intra- and postoperative complications. Results: The groups were comparable with respect to age and duration of follow-up. Median time to complications was 90.3 and 10.7 months in Group 1 and Group 2, respectively (p = 0.007). The complication rate was 40% and 58.3% in Group 1 and 2, respectively (p = 0.001). Complete continence was obtained in 80% of patients from Group 1 and 33.3% of men from Group 2A (p = 0.001). Conclusions: The analysis indicates that cuff placement around the prostatic urethra results in better continence and is characterised by fewer complications. This method is dedicated for patients who have not had the prostate gland removed. Due to the retrospective nature of this analysis and small groups of patients, it is not possible to formulate ultimate recommendations.

Effect of fermented rapeseed meal in the mixture for growing pigs on the gastrointestinal tract, antioxidant status, and immune response.

The ban on the use of zinc oxide has increased interest in probiotics, prebiotics, synbiotics and organic acids, as well as fermented components in the diet of weaned piglets. This study assessed the effect of 8% fermented rapeseed meal in weaner diets on characteristics of the gastrointestinal tract, the small intestinal microbiota, and immune and antioxidant status. The effects were determined by measuring biochemical and haematological blood parameters, levels of class G, A and M immunoglobulins and IL-6, and the antioxidant potential of the plasma. After slaughter, the gastrointestinal tract was measured, the viscosity of the digesta was determined, and microbiological tests were performed. The results showed that the fermented component reduced the viscosity of the digesta and the length of segments of the gastrointestinal tract. It caused a statistically significant increase in lactic acid bacteria and a decrease in total bacteria. The haematological and biochemical analyses of the blood confirmed the biological activity of the fermented component. Pigs from group FR had significantly higher haemoglobin levels (p = 0.001), RBC count (p = 0.015), and haematocrit (Ht) value (p < 0.001) than the control animals. A diet including 8% rapeseed meal fermented using Bacillus subtilis strain 87Y benefits gastrointestinal function by stabilizing and improving the function of the bacterial microbiota, inhibiting growth of certain pathogens, and strengthening immunity.
