Abstract
Adipocytes play a key role in energy storage and homeostasis. Although the role of transcription factors in adipocyte differentiation is known, the effect of endogenous metabolites of low molecular weight remains unclear. Here, we analyzed time-dependent changes in the levels of these metabolites throughout adipocyte differentiation, using metabolome analysis, and demonstrated that there is a positive correlation between cyclic adenosine diphosphate ribose (cADPR) and Pparγ mRNA expression used as a marker of differentiation. We also found that the treatment of C3H10T1/2 adipocytes with cADPR increased the mRNA expression of those marker genes and the accumulation of triglycerides. Furthermore, inhibition of ryanodine receptors (RyR), which are activated by cADPR, caused a significant reduction in mRNA expression levels of the marker genes and triglyceride accumulation in adipocytes. Our findings show that cADPR accelerates adipocytic differentiation via RyR pathway.

Abstract
Cardiovascular disease (CVD) is one of the primary causes of death around the world. This study aimed to identify risk factors associated with CVD mortality using data from the National Health and Nutrition Examination Survey (NHANES). We created three models focusing on dietary data, non-diet-related health data, and a combination of both. Machine learning (ML) models, particularly the random forest algorithm, demonstrated robust consistency across health, nutrition, and mixed categories in predicting death from CVD. Shapley additive explanation (SHAP) values showed age, systolic blood pressure, and several other health factors as crucial variables, while fiber, calcium, and vitamin E, among others, were significant nutritional variables. Our research emphasizes the importance of comprehensive health evaluation and dietary intake in predicting CVD mortality. The inclusion of nutrition variables improved the performance of our models, underscoring the utility of dietary intake in ML-based data analysis. Further investigation using large datasets with recurring dietary recalls is necessary to enhance the effectiveness and interpretability of such models.

Abstract
There is limited information available about the physiological content of glyceraldehyde, a precursor of toxic advanced glycation end products. The conventional derivatization method for aldoses using 1-phenyl-3-methyl-5-pyrazolone did not allow reproducible quantification of glyceraldehyde due to the instability of glyceraldehyde compared to other aldoses. We optimized the derivatization condition to achieve high and reproducible recovery of derivatives for liquid chromatography tandem mass spectrometry quantification. Based on the stability of glyceraldehyde during sample preparation and high recovery of spiked standard, the present method provides reproducible quantification of glyceraldehyde in the body. The glyceraldehyde contents in fasting conditions in the rodent liver (mice: 50.0 ± 3.9 nmol/g; rats: 35.5 ± 4.9 nmol/g) were higher than those in plasma (9.4 ± 1.7 and 7.2 ± 1.2 nmol/mL). The liver glyceraldehyde levels significantly increased after food consumption (p < 0.05) but remained constant in the plasma. High fat diet feeding significantly increased plasma glyceraldehyde levels in mice (p < 0.005). In healthy human volunteers, the plasma glyceraldehyde levels remained unchanged after the consumption of steamed rice. In patients with type 2 diabetes, the plasma glyceraldehyde level was positively correlated with the plasma glucose level (r = 0.84; p < 0.0001).

Abstract
Wheat dextrin soluble fibre may have metabolic and health benefits, potentially acting via mechanisms governed by the selective modulation of the human gut microbiota. Our aim was to examine the impact of wheat dextrin on the composition and metabolic activity of the gut microbiota. We used a validated in vitro three-stage continuous culture human colonic model (gut model) system comprised of vessels simulating anatomical regions of the human colon. To mimic human ingestion, 7 g of wheat dextrin (NUTRIOSE® FB06) was administered to three gut models, twice daily at 10.00 and 15.00, for a total of 18 days. Samples were collected and analysed for microbial composition and organic acid concentrations by 16S rRNA-based fluorescence in situ hybridisation and gas chromatography approaches, respectively. Wheat dextrin mediated a significant increase in total bacteria in vessels simulating the transverse and distal colon, and a significant increase in key butyrate-producing bacteria Clostridium cluster XIVa and Roseburia genus in all vessels of the gut model. The production of principal short-chain fatty acids, acetate, propionate and butyrate, which have been purported to have protective, trophic and metabolic host benefits, were increased. Specifically, wheat dextrin fermentation had a significant butyrogenic effect in all vessels of the gut model and significantly increased production of acetate (vessels 2 and 3) and propionate (vessel 3), simulating the transverse and distal regions of the human colon, respectively. In conclusion, wheat dextrin NUTRIOSE® FB06 is selectively fermented in vitro by Clostridium cluster XIVa and Roseburia genus and beneficially alters the metabolic profile of the human gut microbiota.

Abstract
AIM To review special safety topics associated with sildenafil and to document the tolerability of 50- and 100-mg doses, overall and by age, in men with erectile dysfunction (ED). METHODS Data were collated from 67 double-blind placebo-controlled (DBPC) trials (> 14,000 men) conducted by the manufacturer and from the manufacturer's postmarketing safety database (39,277 patients). The DBPC data were stratified by dose, starting dose and age (> or = 65 and > or = 75 years). Special safety topics included cardiovascular risk, priapism, non-arteritic anterior ischaemic optic neuropathy (NAION), impaired renal and hepatic function, drug interactions (i.e. nitrates, cytochrome P3A4 inhibitors, other ED therapies and alpha-blockers) and incorrect use. RESULTS Sildenafil was well tolerated at a dose of 50 or 100 mg in men with ED, overall, in those aged > or = 65 years, and in those aged > or = 75 years. Analyses of the databases did not reveal any causal link between sildenafil and cardiovascular events, or any new safety risks relating to cardiovascular events, priapism, NAION, hearing loss or drug interactions. In the small number of men with moderate impairment of renal function or hepatic function who were treated with sildenafil in DBPC trials, the safety profile was similar to that in men with no impairment of renal or hepatic function. Overdose with sildenafil was rare in the ED population. No new safety issues, emerging trends or adverse reactions were identified in conjunction with overdose, dependence, abuse or misuse. CONCLUSION This collated review confirms generally the good tolerability and established safety profile of sildenafil 50 and 100 mg in men with ED and reveals no new safety issues.

Abstract
AIM To assess the incidence of serious cardiovascular disease (CVD) events [i.e. myocardial infarction (MI) and stroke] and all-cause mortality in men with erectile dysfunction (ED) who received prescriptions for sildenafil. METHODS The International Men's Health Study (IMHS) was a prospective, observational cohort study of patients with ED and a new or existing prescription for sildenafil. Baseline and follow-up questionnaires provided information on demographics, CVD risk factors and ED. Postevent questionnaires were mailed to patients following possible nonfatal CVD events to collect information related to exposure to sildenafil/ED treatments before the event. RESULTS Thirty-five CVD events were reported in 30 patients in the analysis set (n = 3813). The incidence of all-cause mortality, MI and stroke was 0.4, 0.6 and 0.1 per 100 patient-years of observation respectively. Among the six men who reported using sildenafil in the month before a nonfatal CVD event, two reported use in the 24 h before the event. CONCLUSION The results of the IMHS support previous reports that ED and CVD are often comorbid and share risk factors.

Abstract
AIMS This report describes patterns of treatment changes with the phosphodiesterase type 5 (PDE5) inhibitors tadalafil, sildenafil and vardenafil, and variables associated with those treatment changes, during the 6-month, prospective, pan-European Erectile Dysfunction Observational Study (EDOS). METHODS EDOS observed 8047 men > or = 18 years old with erectile dysfunction (ED), who began or changed ED therapy as part of their routine healthcare. Patients could change ED treatment at any time during EDOS. Data were collected at baseline and at 3 (+/- 1) and 6 (+/- 1) months. Analyses included ED treatment-naïve patients with complete follow-up who were prescribed a PDE5 inhibitor at baseline (n = 4026). RESULTS Most patients, regardless of what PDE5 inhibitor they were prescribed at baseline, continued on that same PDE5 inhibitor throughout the study. Continuation rates were approximately 89% in the tadalafil cohort, vs. 63-64% in the sildenafil and vardenafil cohorts. The variables most strongly associated with increased risk of switching were prescription of sildenafil or vardenafil, vs. tadalafil, at baseline (odds ratios 4.43 and 4.14 respectively; p < 0.0001). Of patients who switched from tadalafil to another treatment, nearly 25% had switched back to tadalafil by study end. In contrast, of patients who switched from sildenafil or vardenafil, < 10% from each cohort had switched back to their original treatment by study end. CONCLUSION The data suggest that tadalafil treatment in treatment-naïve ED patients may increase their likelihood of treatment continuation. These findings should be interpreted conservatively due to the observational nature of the study.

Abstract
BACKGROUND AND OBJECTIVE Erectile dysfunction (ED) is caused by a large range of organic, psychological, psychiatric, interpersonal and pharmacological factors. Numerous scientific publications mention the loss of self-esteem as a collateral effect of ED, with a very probable affectation of the subject's self-confidence. The objective of this study was to evaluate the self-esteem and self-confidence of subjects with ED and to compare them with a group of non-ED subjects. SUBJECTS AND METHOD An epidemiological, cross-sectional, observational, comparative and multicentric study was conducted. General Practitioners selected 405 men older than 18 years in which they suspected ED. All the participants had to complete the self administered form of the Spanish version of the Rosenberg self-esteem scale and the Spanish culturally adapted version of the Johnson and McCoy self-confidence scale. After that, patients were referred to the urologist in order to confirm the ED diagnosis. RESULTS The statistical analysis of the data showed that the subjects with ED obtained significantly lower scores in the self-confidence and self-esteem scales than the non-ED subjects (p < 0.01). DISCUSSION The results of this study show the loss of self-confidence and self-esteem that suffer patients with ED.

Abstract
The urologist/andrologist is the specialist responsible for diagnosis and treatment of health problems related to the genitourinary tract, and his or her participation in comprehensive care for a patient with erectile dysfunction (ED) is fundamental and often indispensable. The urologists/andrologists should characterize the origin of ED because of their knowledge and familiarity of all diagnostic tests and second- and third-line therapy. The origin of ED is important to determine for various reasons, such as young people suitable for etiologic treatment, medicolegal reasons, or patients' wishes for a better understanding of their condition. A review of the diagnostic tests available as well as indications for second- and third-line therapy is presented. The close relationship between ED and urological disorders, such as benign prostatic hyperplasia, prostate cancer and their treatments, and renal failure, in association with penile conditions like Peyronie's disease, priapism, and possible androgen deficiency in men older than 50 years, places the urologist at the center of integrated treatment of male ED.

Abstract
PURPOSE We determined the prevalence of and risks factors for erectile dysfunction in Spain in a cross-sectional study. MATERIALS AND METHODS A total of 2,476 noninstitutionalized Spanish men 25 to 70 years old were interviewed at home and answered a self-administered questionnaire of 71 items, including 2 instruments to define erectile dysfunction, a simple self-assessment question to estimate erectile function and the International Index of Erectile Function. Data on disease, medication and toxic habits were also obtained. RESULTS With an overall participation rate of 75% the prevalence of erectile dysfunction according to the simple question was 12.1%. According to the erectile function domain of the International Index of Erectile Function the overall prevalence was 18.9%. Several independent risk factors were significantly associated with the probability of erectile dysfunction. Some differences arose according to the tool used to define the condition. However, there was a strong relationship of patient age with frequency or severity no matter which instrument was used to define erectile dysfunction. Diabetes (age adjusted odds ratio 4), high blood pressure (odds ratio 1.58), high cholesterol (1.63), peripheral vascular disorder (2.63), lung disease (3.11), prostate disease (2.93), cardiac problems (1.79), rheumatism (2.37) and allergy (3.08) were significantly associated with erectile dysfunction. Drug intake, which respondents called medication for nerves and sleeping pills, correlated strongly (odds ratio 2.78 and 4.27, respectively), as did tobacco use (2.5) and alcohol consumption (1.53). CONCLUSIONS This study provides data on the prevalence of and risks factors for erectile dysfunction in Spain. The relationship of erectile dysfunction with certain risk factors, such as cardiovascular risk factors and drugs intake, are well known and our study corroborates these associations. Other associations with erectile dysfunction, such as prostate disease, allergy and rheumatism, support findings in previous reports, although to our knowledge the pathophysiological mechanisms remain unclear. Estimating the strength of the association of erectile dysfunction with distinct risk factors in terms of odds ratios enabled us to identify the factors to pursue when seeking to prevent erectile dysfunction. Furthermore, the relationship of tobacco with erectile dysfunction, which has been controversial in previous series, was well characterized in our study.

Abstract
Six patients in this series of 543 renal transplants (1.10%) suffered a post-transplant renal segmental infarct of the donor kidney because of occlusion of an accessory renal artery. Five grafted kidneys had multiple renal arteries. Patients presented with symptoms of a caliceal fistula and were treated by partial (25 to 40%) transplant nephrectomy, followed by closure and tissue coverage with either parietal peritoneum (4 patients) or lyophilized human dura mater sealed with fibrin (2). In 2 cases the renal ischemia and necrosis involved the ureter, and a pyelo-pyelostomy was performed. One patient died of cardiorespiratory complications immediately postoperatively. Five years postoperatively all kidneys functioned well without recurrence of fistula and 5 patients returned to a normal life-style. The combination of radical excision and tissue closure, plus ureteral substitution when needed was an effective treatment that prevented loss of the graft.
