This systematic review investigates the intersection of early-onset colorectal cancer (EOCRC), sexual functioning, and associated quality of life (QoL), aiming to understand the comprehensive impact of EOCRC on these critical dimensions. Through an extensive search across PubMed, Scopus, and Embase up until November 2023, this study synthesized evidence from the literature while adhering to PRISMA guidelines. The studies included EOCRC patients under 50 years, which examined sexual functioning and QoL using validated instruments, and were published in English. After a rigorous screening process, five relevant studies were identified from an initial pool of 2184 articles. This review includes data from five studies involving 2031 EOCRC patients. The key findings revealed a high prevalence of sexual dysfunction, with up to 50% of men experiencing impotence and 58% reporting sexual dysfunction, alongside 36% of women in some studies. Pain was described by 12% to 31% of patients. Anxiety and depression were notably prevalent, affecting up to 69% of participants. EOCRC profoundly impacts sexual functioning and QoL, with a significant prevalence of sexual dysfunction and psychological distress among affected individuals. These findings suggest the need for oncological management strategies that include not only medical treatment but also psychological support and sexual health interventions. This systematic review emphasizes the importance of holistic patient care approaches, advocating for further research and clinical attention to address the complex needs of younger EOCRC patients.

Background/Objectives: Urinary tract infections (UTI) represent a global problem with implications for mortality and morbidity. Published data present different bacterial incidences and different antibiotic resistance. The objective of our study is to evaluate the bacteria distribution in positive urine cultures in a mixed adult population and evaluate the differences in antibiotic resistance in in- and outpatients. Methods: We analyzed 1186 positive urine cultures in 2021 from the Emergency County Hospital “Pius Brinzeu” from Timisoara, Romania. We evaluated the bacteria distribution and antibiotic resistance stratified by in and outpatients from a mixed adult population. Results: The median age was 67, with 65.7% females and 28.5% were outpatients. In inpatients, the most commonly identified bacteria was E. coli, followed by Enterococcus spp., and Klebsiella spp., while in outpatients, E. coli, Enterococcus spp., and Klebsiella spp. were the leading ones. Overall, E. coli presented the highest resistance rate to ampicillin, Enterococcus spp. to ciprofloxacin, Klebsiella spp. to cephalosporins, and Proteus spp. to trimethoprim/sulfamethoxazole. Inpatients presented higher resistance rates for E. coli to ceftazidime, cefuroxime, gentamycin, ciprofloxacin, and trimethoprim/sulfamethoxazole, Klebsiella spp. to most cephalosporin, gentamycin and levofloxacin, Proteus spp. to gentamycin and Enterococcus spp. to gentamycin and quinolones when compared to outpatients. The highest incidence of extensively drug-resistant (XDR) bacteria was among Acinetobacter baumanii, followed by Pseudomonas spp., and Serratia spp. Conclusions: susceptibility. Bacteria identified in inpatients’ positive urine cultures present higher resistance rates to several antibiotics. Our study could be a foundation for a local or even national guideline for the antibiotic treatment of urinary tract infections.

Background: Sleep quality (SQ) and physical activity (PA) are among the strongest behavioral determinants of healthy aging, while dietary behavior and psychological factors act as complementary modulators of these relationships. Although each domain has been studied extensively, their combined influence on subjective life expectancy (SLE)—an individual’s perceived likelihood of living to an advanced age—remains largely unexplored. Methods: This narrative review synthesizes evidence from sleep science, exercise physiology, behavioral medicine, and psychological aging. Literature published between January 2015 and 15 December 2025 was examined across PubMed, Scopus, and Web of Science using integrative keyword strategies. Studies addressing SQ, PA, circadian rhythms, psychological health, SLE, or aging-related outcomes were included. Results: The review identifies several converging pathways linking sleep and PA to aging trajectories. Sleep architecture, circadian stability, metabolic regulation, inflammatory balance, and autonomic function represent key biological mechanisms. PA contributes through improvements in mitochondrial efficiency, VO2max, muscle metabolism, and anti-inflammatory signaling (IL-6 as a myokine). Across studies, both sleep and PA strongly influence psychological health, health perception, and future-oriented expectations, within a broader lifestyle context supported by nutritional status and dietary quality. SLE emerges as a central psychological mediator that shapes motivation, adherence to health behaviors, and long-term health outcomes. Contextual moderators—including age, gender, socioeconomic status, cultural norms, and wearable technology engagement—further influence these relationships. Conclusions: SQ and PA form the core behavioral components of a dynamic system that is further shaped by dietary behavior and psychological well-being and centered on SLE. Our proposed integrative model positions SLE as a key psychological link between lifestyle behaviors and longevity. This framework is hypothesis-generating and requires empirical validation through future longitudinal and interventional studies, underscoring the need for multidomain research integrating behavioral, biological, nutritional and psychological indicators of aging.

Background: Postprandial triglyceride (TG) metabolism represents a dynamic dimension of lipid physiology that complements conventional fasting lipid assessment. Although low-density lipoprotein cholesterol (LDL-C) remains the primary therapeutic target in cardiovascular prevention, residual cardiovascular risk persists in many individuals despite apparently adequate fasting lipid control. Because most individuals spend the majority of their waking hours in a fed state, postprandial TG responses may provide clinically relevant insight into metabolic flexibility, dietary exposure, and the efficiency of TG-rich lipoprotein clearance. Methods: This narrative review was conducted using a literature search guided by predefined themes, keywords, and databases, without following a formal systematic review protocol. Randomized controlled trials, observational studies, meta-analyses, and major reviews addressing postprandial lipid metabolism, dietary determinants, and cardiometabolic risk were included, with priority given to human studies. Results: Postprandial TG responses are strongly influenced by dietary composition, eating patterns, and metabolic health. Individuals with insulin resistance, type 2 diabetes, obesity, and metabolic-associated steatotic liver disease (MASLD) frequently demonstrate exaggerated or prolonged postprandial lipemia even when fasting TG concentrations appear acceptable. While circulating TGs serve as practical clinical markers of postprandial lipid handling, cholesterol-enriched remnant lipoproteins more closely reflect atherogenic burden. Nutritional interventions, weight management, and physical activity consistently improve postprandial TG dynamics, whereas pharmacologic therapy provides additional benefit in selected high-risk patients. Non-fasting TG measurements may provide additional insight into postprandial lipid metabolism and residual cardiovascular risk, although standardized protocols and validated clinical thresholds remain to be established. Conclusions: Postprandial TG metabolism provides clinically meaningful information beyond fasting lipid measurements and represents a useful adjunct for refining residual cardiovascular risk assessment. Although standardized protocols remain limited, integrating nutritional and clinical perspectives may support a more comprehensive and individualized approach to cardiometabolic prevention.

Background: Radical cystectomy (RC) remains associated with substantial perioperative morbidity despite advances in minimally invasive surgery and reconstructive techniques. Comparisons between intracorporeal reconstruction, robotic-assisted approaches, and urinary diversion strategies are frequently confounded by clinical heterogeneity and patient selection. This study aimed to perform a stratified surgical systematic review evaluating perioperative outcomes across distinct reconstructive pathways following RC. Methods: A PRISMA-guided systematic review identified comparative studies evaluating intracorporeal versus extracorporeal/open orthotopic neobladder reconstruction, robotic-assisted versus open radical cystectomy in frail patients undergoing ureterocutaneostomy, and ileal conduit versus orthotopic urinary diversion. Analyses were performed within predefined clinical modules to preserve surgical context. Outcomes were expressed as odds ratios (ORs) with 95% confidence intervals (CIs), complemented by rare-event sensitivity analyses and exploratory absolute risk metrics, including number needed to treat or harm (NNT/NNH). Continuous outcomes such as estimated blood loss and length of hospital stay were assessed descriptively. Results: Three comparative observational cohorts met inclusion criteria. Intracorporeal neobladder reconstruction and robotic-assisted cystectomy demonstrated consistent reductions in transfusion rates and favourable trends in perioperative morbidity. In frail patient populations, robotic surgery showed reduced intraoperative burden without increased readmission or mortality. Ileal conduit diversion was associated with increased wound-related complications and infectious outcomes; however, these findings likely reflect baseline differences in patient frailty and selection. Rare-event sensitivity analyses confirmed directional consistency of treatment effects despite wide confidence intervals. Integration of absolute risk differences and NNT/NNH metrics provided clinically interpretable context for stratified outcomes. Conclusions: Minimally invasive and intracorporeal strategies following radical cystectomy may reduce perioperative burden, whereas diversion type primarily influences complication patterns rather than overall morbidity. A stratified analytical framework integrating relative and absolute effect measures may offer a more clinically meaningful approach to evaluating reconstructive strategies in heterogeneous surgical populations.

Background/Objectives: Urinary tract infections represent a global problem with implications on mortality and morbidity. Published data present different bacterial incidence and different antibiotics resistances. With this study, we aimed to evaluate bacteria distribution and antibiotic resistance in a tertiary care hospital from the Western part of Romania. Methods: we evaluated all the positive urine culture from the year 2021 from the Emergency County Hospital “Pius Brinzeu” from Timisoara, Romania. We evaluated 1264 urine cultures and identified the following bacteria: Escherichia Coli, Klebsiella spp, Proteus spp., Pseudomonas auruginosa, Staphylococcus aureus, Enteroccocus spp., Enterobacter spp., Acinetobacter baumanii, Providencia spp., Corynebacterium spp. Results: Median age was 67 with 65.6% females. Diabetes mellitus incidence was 12%. Most common bacteria was E. coli – 44.1%, followed by Enterococcus spp. – 17.1%, Klebsiella spp. -15.7% and Proteus spp. – 5.4% E. coli presented the highest resistance rate to amoxicillin-clavulanic acid (50%), Enterococcus spp. to ciprofloxacin (71.3%), Klebsiella spp. to piperacillin-tazobactam (43.3%) and Proteus spp. to trimetroprime-sulfometoxazole (33%). The highest incidence of MDR bacteria was among Acinetobacter baumanii (40%), followed by MRSA (31.8%) and Klebsiella spp. (25.3%). Conclusions: Bacteria distribution is similar in all the Romanian regions among the positive urine cultures. Antibiotics resistance differ among regions and the MDR bacteria incidence is rising.
