Background/Objectives: The trajectory of influenza hospitalization burden from pre-COVID-19 pandemic baseline through post-pandemic recovery remains poorly characterized at the national level. This study characterized phase-stratified burden and seasonal structure, quantified racial and ethnic disparities, and assessed whether post-pandemic seasons represent anomalous departures from pre-pandemic expectations. Methods: Sixteen complete seasons of FluSurv-NET surveillance data (2009–2010 through 2024–2025; 509 observation weeks) were analyzed across pre-pandemic, disruption, and recovery phases using OLS regression with effect-size estimation, bootstrapped age-adjusted rate ratios, seasonal-trend decomposition (STL), Prophet time-series forecasting, and Isolation Forest anomaly detection. Results: Mean peak weekly hospitalization rate nearly doubled from pre-pandemic to recovery (5.1 to 11.1 per 100,000), cumulative seasonal burden increased from 46.3 to 87.0 per 100,000, and median peak timing advanced from MMWR week 9 to week 50. STL decomposition revealed a marked shift from weak pre-pandemic seasonality (Fs = 0.14) to substantially stronger annual regularity (Fs = 0.98) across three recovery seasons, with threefold amplitude increase. Non-Hispanic Black persons had rate ratios of 1.72, 2.16, and 1.99 relative to White persons across phases; American Indian and Alaska Native persons showed the highest disruption-phase ratio (2.24, 95% CI 1.90–3.53), based on two contributing seasons. A flat-growth Prophet model detected first exceedance in February 2020, outperforming a linear-growth specification on held-out validation. Isolation Forest identified 2017–2018, 2023–2024, and 2024–2025 as robust anomalies across all contamination thresholds. Conclusions: Post-COVID-19 pandemic influenza recovery is characterized by intensified and restructured seasonality, persistent racial and ethnic disparities, and anomalous burden exceeding pre-pandemic projections, identified independently by time-series forecasting and unsupervised anomaly detection.

Background: Carbapenem-resistant K. pneumoniae (CRKP) represents a major challenge in hospitalized patients because of its association with healthcare exposure, restricted antimicrobial options, and adverse clinical outcomes. Microbiological isolation alone does not define invasive disease; therefore, clinical interpretation requires separation of colonization, localized infection, invasive infection, and carbapenem-resistant Enterobacterales (CRE)-associated sepsis. This study evaluated epidemiological features, resistance phenotypes, treatment adequacy, and clinical outcomes among hospitalized adults with K. pneumoniae isolates, using a clinical framework that distinguishes colonization from active infection and invasive disease. Methods: This single-center retrospective observational cohort study included 157 consecutive adults admitted between January and July 2025 to a tertiary-care hospital with at least one microbiologically confirmed K. pneumoniae isolate recovered from clinical specimens and/or CRE surveillance rectal swabs. Isolates were assigned hierarchically to four mutually exclusive phenotypic groups: carbapenem-susceptible K. pneumoniae (CSKP), extended-spectrum beta-lactamase (ESBL)-producing carbapenem-susceptible K. pneumoniae (ESBL), carbapenem-resistant non-carbapenemase-producing K. pneumoniae (CRKP), and carbapenemase-producing K. pneumoniae (CP-KP). A prespecified secondary analysis compared carbapenem-resistant isolates (CRKP + CP-KP) with non-carbapenem-resistant isolates (CSKP + ESBL). Clinical adjudication distinguished colonization-only cases, non-invasive infection, bloodstream infection, device-associated infection, and CRE-associated sepsis; ventilator-associated pneumonia (VAP) was considered when source data allowed reliable attribution. Sepsis was defined according to Sepsis-3 criteria; quick Sequential Organ Failure Assessment (qSOFA) was used only as a bedside screening tool. Statistical tests were selected according to variable type, distribution, and expected cell counts. Results: The cohort comprised 157 unique patients, with a median age of 71 years (interquartile range [IQR], 61–76). Current CRE colonization was documented in 79/154 patients with available colonization status (51.3%). Complete-case in-hospital mortality was higher in the carbapenem-resistant group (CRKP + CP-KP, n = 46) than in the non-carbapenem-resistant group (CSKP + ESBL, n = 111): 11/42 (26.2%) versus 5/108 (4.6%; Fisher exact odds ratio (OR) 7.31, 95% confidence interval (CI) 2.36–22.65; p < 0.001); overall complete-case mortality was 16/150 (10.7%). Multivariable logistic regression for carbapenem resistance (N = 150; five prespecified covariates; events per variable (EPV) = 9.0) identified age 65 years or older (adjusted odds ratio [aOR] 3.78, 95% CI 1.32–10.86), recent hospitalization within 30 days (aOR 2.56, 95% CI 1.16–5.63), and current colonization (aOR 2.96, 95% CI 1.24–7.05) as independent predictors. CRE-associated sepsis was excluded a priori because of definitional circularity with the case definition. Male sex showed a non-significant protective trend (aOR 0.50, 95% CI 0.22–1.12). CRE-associated sepsis showed a strong bivariate association with carbapenem resistance (OR 9.90, 95% CI 3.91–25.09; p < 0.001), and this association is reported descriptively because the variable was excluded from the multivariable model owing to definitional circularity. Model performance was acceptable, with area under the curve (AUC) 0.77, Hosmer–Lemeshow p = 0.95, and Nagelkerke R² = 0.25. Of 99 molecularly characterized isolates, OXA-48-like was detected in 78 (78.8%), NDM in 71 (71.7%), KPC in 6 (6.1%), and NDM + OXA-48-like dual production in 54 (54.5%); VIM and IMP were uniformly negative. Conclusions: In this high-risk hospital cohort, carbapenem resistance in K. pneumoniae was associated with advanced age, recent healthcare exposure, current CRE colonization, and a pronounced unadjusted mortality signal. Interpretation of sepsis and mortality requires explicit separation of colonization from active infection and invasive disease. These findings support intensified CRE surveillance, source-specific clinical interpretation, rapid resistance detection, and risk-adapted empirical antimicrobial strategies in high-risk hospital settings.

Background: Hospitalized adults with chronic kidney disease (CKD) experience high morbidity and mortality. Acute inpatient events frequently occur in combination, yet most studies evaluate individual conditions in isolation. Acute hemodynamic and vascular stressors may represent interacting physiological stressors that define heterogeneous patterns of inpatient risk. Methods: Acute hemodynamic stressors (sepsis, shock, acute decompensated heart failure, and mechanical ventilation) and vascular stressors (acute myocardial infarction, major bleeding, stroke, pulmonary embolism, and deep vein thrombosis) were identified using ICD-10-CM and ICD-10-PCS codes. Stressor burden was defined as the number of stressors (0, 1, 2, or ≥3). Hospitalizations were categorized into mutually exclusive domains: none, hemodynamic only, vascular only, or both. Survey-weighted multivariable regression models examined associations with mortality, acute kidney injury (AKI), length of stay (LOS), and hospital charges. Prespecified sensitivity analyses excluded inter-hospital transfers, and interaction analyses assessed modification by age. Results: Among 1,062,813 CKD hospitalizations, 66.1% experienced at least one acute stressor. Increasing stressor burden demonstrated a marked dose–response relationship with mortality, with adjusted odds ratios of 2.15 (95% CI: 2.08–2.23), 7.36 (95% CI: 7.09–7.64), and 31.65 (95% CI: 30.40–32.95) for 1, 2, and ≥3 stressors, respectively. Increasing stressor burden was also associated with higher odds of AKI, longer LOS, and greater hospital charges. Significant dose–response relationships were observed for all outcomes (all P-trend < 0.001). Isolated hemodynamic stressors were associated with greater mortality risk than isolated vascular stressors (aOR: 4.97 vs. 2.15), while hospitalizations experiencing both domains had the greatest risk (aOR: 13.10, 95% CI: 12.52–13.71). These findings were robust in sensitivity analyses excluding inter-hospital transfers. The relative increase in mortality associated with higher stressor burden was greater among patients younger than 65 years than among older adults (P for interaction <0.001). Conclusions: Acute hemodynamic and vascular stressors define heterogeneous patterns of inpatient risk among hospitalized adults with CKD. Both cumulative stressor burden and stressor domain are strongly associated with mortality, AKI, and resource utilization, with robust dose–response relationships that highlight acute physiological stress as an important determinant of inpatient outcomes in CKD.

Objectives: To investigate the clinical and epidemiological characteristics of respiratory syncytial virus (RSV)-associated acute lower respiratory tract infection (ALRTI) among hospitalized children in the Baoding region of Hebei Province, China. Methods: The study subjects were inpatients diagnosed with ALRTI at a pediatric hospital in Baoding between 1 June 2017 and 31 December 2024. A retrospective analysis was conducted on the detection of RSV and other common respiratory viruses in respiratory specimens to evaluate the clinical epidemiological characteristics of RSV. Viral detection was performed using immunofluorescence (IF) or polymerase chain reaction (PCR) assays. Results: The overall RSV detection rate was 16.8% (4945/29,399), with 6.7% co-infections. The RSV detection rate was 29.8% (2604/8729) in infants younger than 1 year and 18% (942/5232) in the 1-year-old group, then showing a decreasing trend with increasing age, with the lowest rate of 3.8% (283/7366) observed in the ≥5 years age group. The RSV detection rate decreased from 19.9% before the COVID-19 pandemic (2017–2019) to around 13% during and after the pandemic (χ² = 233.732, p < 0.001), accompanied by a drop in the proportion of children under 2 years from 78.5–79.6% before the COVID-19 pandemic to 42.1–51.1% after the pandemic period (χ² = 387.565, p < 0.001). RSV seasonality shifted from a typical single winter–spring peak in the pre-COVID-19 era to a markedly reduced peak during the pandemic, in contrast to a delayed summer–autumn “off-season” pattern observed in the post-pandemic period. Conclusions: RSV remains the predominant pathogen for hospitalized ALRTI in Baoding, particularly among infants. Detection rates of RSV declined with increasing age. The COVID-19 pandemic has profoundly impacted RSV prevalence patterns and seasonality, underscoring the critical need for long-term surveillance. Full article

Background/Objectives: Community hospitals can be a valuable and cost-effective resource for elderly people, especially in rural areas. Their aim is to promote self-reliance, prevent unnecessary hospital admissions, and facilitate rapid recovery after acute illness. The widespread adoption of intermediate care facilities helps alleviate hospital overcrowding by preventing clinical deterioration through advanced and continuous nursing care. An intermediate care unit was established in a rural area of central Italy. This study aims to describe the impact of a community hospital on patients’ functional status from admission to discharge, describing a real-life model. Methods: This single-center descriptive study examines trends in the quality of care provided. Data were retrieved from anonymized electronic clinical records. Statistical analyses were performed using descriptive statistics, paired t-tests, and Pearson correlation coefficients. Results: A total of 532 residents (mean age 80.7 ± 13.2 years; 61% female) were admitted to the community hospital between January 2022 and September 2025. The mean length of stay was 15.2 ± 7.6 days, with a mean improvement in Modified Barthel Index score of 5.24 ± 7.95 (p < 0.05). Most patients (81.8%) were discharged home, while 6.0% required hospitalization. No readmissions were recorded in 2025. Clinical risk events occurred only in 1.2% of the total. Nursing specialization increased during the study period, correlating with improved patient outcomes (R = 0.88). Conclusions: This descriptive cross-sectional study in a rural nurse-led intermediate care unit found relatively short lengths of stay, high rates of home discharges and modest, but statistically significant, improvements in functional autonomy.

Background: Post-thyroxine treatment of thyroid dysfunction remains a clinical concern, especially in Middle Eastern populations. Methods: This descriptive cross-sectional study was conducted in 2023 at King Fahad Hospital, Hufof, Kingdom of Saudi Arabia. Of the 237 patients treated with L-thyroxine (L-T4) for hypothyroidism, 163 patients, almost exclusively females (152 females, 11 males), met the inclusion criteria and were enrolled. Thyroid hormones, lipid profiles, and 25-hydroxyvitamin D (25OH-D) were measured using standard laboratory assays. Results: Only 57% of patients achieved euthyroid status following L-T4 treatment, while 12.3% developed post-thyroxine-treatment (PTT) hyperthyroidism, and 30.7% developed PTT hypothyroidism. Older age was significantly associated with dysthyroidism (p = 0.018), whereas obesity (p = 0.937) and vitamin D levels (p = 0.982) were not. Total cholesterol (TC) and LDLc positively correlated with TSH levels, while elevated triglycerides (TGs) were significantly associated with PTT hyperthyroidism. The two dysthyroid subgroups were comparable across all non-thyroid parameters, including age, BMI, 25(OH)D levels, and lipid fractions. However, free T4 was significantly higher in PTT hyperthyroidism (p < 0.001); free T3 showed a trend toward higher levels in PTT hyperthyroidism (p = 0.052); and TSH was significantly higher in PTT hypothyroidism (p < 0.001). Conclusions: The proportions of patients with PTT hypo- and hyperthyroidism are aligned with international observations. Furthermore, the age was significantly associated with dysthyroidism, and dyslipidemia is the most consistent biochemical correlate of suboptimal thyroid status; however, the associations of PTT dysthyroidism with hypovitaminosis D and BMI were not noticed in this setting.

Background and Objectives: Healthcare-associated infections (HAIs) remain a major challenge in emergency hospital settings, where high patient turnover and empirical antibiotic use may contribute to the emergence and spread of multidrug-resistant organisms. Monitoring antibiotic consumption is essential for antimicrobial stewardship and infection prevention. This study evaluated antibiotic consumption patterns across multiple hospital units and explored their ecological relationship with HAI rates. Materials and Methods: A retrospective observational study was conducted in a tertiary-level emergency hospital in Romania between 1 January 2021 and 31 October 2025. Antibiotic consumption was quantified using Defined Daily Dose per 100 bed-days (DDD/100 bed-days) according to World Health Organization (WHO) methodology and categorized using the WHO Access, Watch, and Reserve (AWaRe) classification. HAI data were collected using standardized surveillance definitions. Statistical analyses were primarily descriptive and exploratory and included graphical trend assessment, simple linear regression for temporal trend description, and Spearman correlation analysis for exploratory ecological co-variation assessment. Results: Antibiotic consumption showed substantial variability across hospital units, without a consistent temporal trend over the study period. The Watch group predominated over the Access group from 2023 onward, while Access antibiotics remained below the WHO-recommended 60% threshold. The highest antibiotic consumption was observed in the Medical Wards, followed by Surgical Wards and the Intensive Care Unit. A total of 27 HAIs were identified (0.27 per 1000 patient-days), with the highest incidence observed in the ICU. The most frequent infections were Clostridioides difficile infections (33.3%) and catheter-associated urinary tract infections (29.6%). Exploratory ecological analyses did not identify robust associations between total antibiotic consumption and HAI rates across hospital units. A numerically elevated co-variation was observed between fluoroquinolone consumption and Clostridioides difficile infection incidence; however, this finding should be interpreted strictly as exploratory and hypothesis-generating. Conclusions: Antibiotic use varied across hospital units, with predominance of broad-spectrum agents and suboptimal adherence to WHO AWaRe targets. Reported HAI incidence remained low and should be interpreted within the limitations of routine surveillance systems and potential under-ascertainment. These findings support the value of continuous institutional surveillance of antibiotic use and HAIs while highlighting the limitations of aggregated ecological analyses. Full article

Background and Objectives: Postoperative pulmonary complications (PPCs) remain an important cause of morbidity after cardiac surgery. Driving pressure (DP), defined as the difference between plateau pressure and positive end-expiratory pressure, has been proposed as a bedside marker of respiratory system mechanics during lung-protective ventilation. However, its relationship with PPCs in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) remains uncertain. This study aimed to evaluate the association between intraoperative DP and PPCs following CPB-supported cardiac surgery. Materials and Methods: This single-center prospective observational study included 99 adult patients undergoing elective cardiac surgery with CPB. All patients were ventilated using a standardized lung-protective strategy with a tidal volume of 6 mL/kg predicted body weight and a fixed PEEP of 5 cmH₂O. Patients were categorized according to intraoperative DP as Group I (DP < 13 cmH₂O, n = 66) and Group II (DP ≥ 13 cmH₂O, n = 33). The primary outcome was a composite PPC endpoint, defined as the occurrence of at least one EPCO-defined pulmonary complication during the postoperative hospital stay. Multivariable logistic regression was performed to assess whether pre-CPB DP was independently associated with PPCs after adjustment for body mass index, CPB time, and age. Results: Patients with DP ≥13 cmH₂O had higher post-CPB and ICU-admission lactate concentrations. Pneumothorax, pleural effusion, atelectasis, CPAP requirement, and prolonged mechanical ventilation were more frequent in the elevated-DP group. Mechanical ventilation duration, ICU stay, and hospital stay were also longer in this group. Composite PPCs occurred in 41 patients (41.4%). Although higher pre-CPB DP showed a non-significant trend toward increased PPC risk in univariable analysis (OR 1.121, 95% CI 0.988–1.273; p = 0.077), it was not independently associated with the composite PPC endpoint after adjustment (adjusted OR 1.091, 95% CI 0.952–1.251; p = 0.212). In contrast, higher pre-CPB DP was significantly associated with prolonged postoperative ventilation and longer mechanical ventilation, ICU, and hospital stay durations. Conclusions: Elevated intraoperative DP was associated with a higher unadjusted burden of PPCs and delayed postoperative recovery after CPB-supported cardiac surgery. However, pre-CPB DP was not an independent predictor of the composite PPC endpoint after adjustment for relevant confounders. These findings suggest that DP may serve as a clinically useful marker of impaired respiratory mechanics and postoperative vulnerability rather than as an independent causal determinant of PPCs.

Background: Sepsis remains a leading cause of morbidity, mortality, and healthcare expenditure worldwide. Despite international guidelines and diagnostic criteria, real-world variability in coding, treatment, and outcomes persist. This retrospective study analyzed 13,994 coded sepsis-related hospitalizations identified through administrative ICD-9-CM algorithms between 2016 and 2024 to evaluate the burden of sepsis, temporal trends, clinical outcomes, and healthcare costs within a regional health system. Methods: Hospitalization data across four local health authorities (ASL 201–204) over an 8-year period were analyzed. The coded sepsis cases were identified using validated ICD-9-CM-based algorithms and classified into four groups according to available microbiological coding: Gram-positive, Gram-negative, anaerobic and unspecified. Variables included patient demographics, length of stay, costs, outcomes (in-hospital and post-discharge mortality) and presence of septic shock. Comparative analyses were conducted using descriptive statistical methods and One-way ANOVA test and chi-squared tests were applied to evaluate the significance of differences. Multivariable logistic regression models were used to identify independent predictors of 6- and 12-month mortality. Results: The dataset included 13,994 coded sepsis-related hospitalizations, with the largest subgroup being ‘unspecified’ (48.0%). Among cases with specified etiology, coded anaerobic sepsis categories, though rare (0.7%), were associated with higher in-hospital mortality (45.5%) and economic burden (avg. € 8563). Mortality remained high at 6 and 12 months across all types, exceeding 50% post-discharge. Increasing age (OR ≈ 1.06 per year) and septic shock (OR ≈ 4.5–4.8) were the strongest independent predictors of mortality. Differences across microbiological groups should be interpreted cautiously given the high proportion of cases without organism-specific coding. Despite a modest reduction in mortality over time, sepsis was associated with persistently high 6- and 12-month mortality, highlighting a substantial long-term burden beyond the acute phase of illness. These findings suggest that sepsis-related hospitalizations are associated with substantial long-term mortality beyond the acute phase of illness. Discussion: These findings underscore the clinical and economic impact of sepsis in hospitalized patients, across microbiological coding categories. The high mortality rate at 6–12 months may support the need for further investigation into structured post-discharge follow-up strategies. Sepsis represents a substantial clinical and economic burden within the regional healthcare system, with persistently elevated short- and mid-term mortality. Incomplete organism-level documentation limits direct etiologic comparisons and highlights the need for improved integration between clinical, microbiological, and administrative data systems. Future research should integrate clinical variables and lab results to enable risk stratification and intervention planning. Full article

The global rise in multidrug-resistant (MDR) fungal pathogens has positioned Candida auris and Candida glabrata as major threats to public health. In recent years, these pathogens have increasingly been reported beyond traditional hospital settings, including neonatal intensive care units, long-term care facilities, oncology wards, and post-pandemic critical care environments. International surveillance bodies, including the Centers for Disease Control and Prevention (CDC), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO), and regional monitoring networks, have documented escalating antifungal resistance, complex outbreak dynamics, and persistent gaps in infection control implementation. C. auris has emerged as a major etiological agent of healthcare-associated outbreaks, particularly in intensive care and neonatal units. Surveillance data indicate that a high proportion of C. auris isolates exhibit resistance to azoles, often exceeding 80% in some regions, while echinocandin resistance remains variable. Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance. Six genetically distinct clades (I–VI) have been identified, with Clades I, III, and IV associated with large-scale outbreaks, whereas available data suggests that Clades II, V, and VI are more geographically restricted, although evidence for the recently described clades remains limited. C. glabrata is increasingly recognized as a major cause of invasive candidiasis, with rising resistance reported across multiple regions. While reduced azole susceptibility was historically predominant, emerging evidence highlights rising dual azole–echinocandin resistance, adaptive microevolution during antifungal therapy, and biofilm-associated tolerance mechanisms. Despite these advances, significant gaps persist in global resistance surveillance and in the mechanistic understanding of virulence and antifungal adaptation. Current mitigation strategies include antifungal stewardship programs, expanded resistance testing, and strengthened surveillance systems. Advances in rapid diagnostic technologies such as matrix-assisted laser desorption ionization–time of flight (MALDI-TOF) mass spectrometry, polymerase chain reaction (PCR)-based assays, and genomic surveillance have improved pathogen identification and outbreak detection, although accessibility remains limited in resource-constrained settings. This review examines emerging epidemiological, genomic, and antifungal resistance trends in C. auris and C. glabrata and highlights key priorities for improving diagnosis, surveillance, stewardship, and management of multidrug-resistant Candida infections.

Background/Objectives: Recent trends show a rising incidence of venous thromboembolism (VTE) that does not correlate with increased mortality; however, population aging and the proliferation of comorbidities are fundamentally reshaping the VTE patient landscape. The aim of this study is to evaluate potential differences in clinical characteristics, comorbidities, and survival rates between patients diagnosed with pulmonary embolism (PE) during the pre-pandemic period (2018–2019) and those diagnosed during the pandemic era (2020–2022). Additionally, as a secondary objective, we analyze the clinical profiles, risk factors, and survival outcomes of patients with and without COVID-19 infection during the 2020–2022 period. Methods: A retrospective observational study was conducted to analyze survival and comorbidities in patients admitted for PE at the Hospital Central de la Defensa ‘Gómez Ulla’ between 2018 and 2022, comparing two periods (2018–2019 and 2020–2022). In addition, a sub-analysis was performed within the second period group comparing patients with and without COVID-19. Results: It was observed that the majority of patients in the first period were men, while in the second period, 55% were women. With regard to comorbidity and risk factors, thrombophilia and dementia were more prevalent in the first period, while asthma was more prevalent in the second period. No differences were found with regard to mortality. Conclusions: Significant differences were observed between the two periods of the study with regard to some comorbidities. Patients with COVID-19 showed a greater tendency toward immobilization and a higher prescription of thromboprophylaxis during hospitalization. Full article

Background: Robot-assisted radical prostatectomy (RARP) is the predominant surgical approach for localized prostate cancer in high-volume centers worldwide. However, comprehensive real-world data describing complete institutional transition from open to robotic surgery remain limited. This study evaluated perioperative and early oncological outcomes of a contemporary RARP cohort and characterized the transition from open radical prostatectomy (ORP) to RARP in a European center. Methods: We analyzed 520 consecutive patients who underwent RARP between January 2023 and December 2025. Perioperative, pathological, and biochemical outcomes were assessed. Biochemical recurrence was defined as prostate-specific antigen ≥0.2 ng/mL. Institutional data from 2011 to 2025 were reviewed to evaluate procedural trends and the transition from ORP to RARP. Surgeon-specific and institutional learning curves were analyzed using operative time and linear regression models. Results: Following the introduction of robotic surgery in 2018, annual RARP volume increased from 37 procedures to 205 in 2025. Since 2023, RARP accounted for more than 99% of all radical prostatectomies. Median operative time decreased from 185 min in 2023 to 165 min in 2025, with consistent downward trends observed across all surgeons. Linear regression confirmed progressive improvement in operative efficiency, with learning rates ranging from −0.22 to −0.92 min per case. Estimated blood loss was minimal, no patients required transfusion, and major complications occurred in four patients (0.8%). Hospital stay decreased from 2 days to predominantly 1 day. During follow-up, 36 patients developed biochemical recurrence or PSA persistence. Biochemical recurrence-free survival differed significantly according to pathological stage (log-rank p < 0.001), with 24-month estimates of 93.7%, 91.5%, and 82.1% for pT2, pT3a, and pT3b disease, respectively. Conclusions: RARP provides favorable perioperative safety, minimal morbidity, and favorable early oncological outcomes in a high-volume setting. The complete institutional transition from ORP to RARP, together with demonstrated surgeon-specific and institutional learning effects, supports the feasibility and safety of implementing RARP as the institutional standard within a structured robotic program.

Background/Objectives: Bariatric surgery is an effective intervention for severe obesity; however, long-term outcomes may be influenced by postoperative dietary behaviors, nutritional status, and complications. In Saudi Arabia, longitudinal evidence on weight trajectories and postoperative diet quality remains limited. The present study aimed at evaluating three-year weight status trends; assessing sociodemographic factors, baseline BMI, and postoperative diet quality; and examining nutrition-related complications following bariatric surgery. Methods: This retrospective longitudinal study included 189 adults who underwent sleeve gastrectomy at two tertiary hospitals in Jeddah, Saudi Arabia. Anthropometric data were obtained from medical records at six time points: preoperative, two weeks, six months, one year, two years, and three years postoperatively. Diet quality and postoperative complications were assessed via structured telephone interviews. Weight outcomes were expressed as percentage of total body weight loss (%TBWL), excess body weight loss (%EWL), excess body mass index loss (%EBMIL), and weight regain. Statistical analyses included Friedman’s test, Mann–Whitney U test, and multiple linear regression. Results: Significant improvements in all weight loss indicators were observed over three years (p < 0.001). Diet quality score was the only significant variable associated with weight loss at three years, with higher scores associated with greater %EWL and %EBMIL. Baseline BMI and DQS were significantly associated with %EWL (Beta = −0.17, 95% CI: −1.72 to −0.13 and Beta = 0.21, 95% CI: 1.37 to 7.12, respectively) and %EBMIL (Beta = −0.15, 95% CI: −1.68 to −0.07 and Beta = 0.24, 95% CI: 1.90 to 7.66, respectively). Age was significantly associated with weight regain (Beta = 0.20, 95% CI: 0.02 to 1.08). Conclusions: Bariatric surgery resulted in sustained weight reduction over three years. Postoperative baseline BMI and diet quality were significantly associated with %EWL and %EBMIL, underscoring the importance of structured nutritional follow-up and counseling. Full article

Background/Objectives: Vancomycin-resistant (VRE) and vancomycin-variable (VVE) Enterococcus spp. represent an increasing clinical challenge due to limited treatment options and the potential for undetected dissemination of such resistance genes. Data on Enterococci genomic epidemiology in healthcare settings remain rather limited. Our study aimed to investigate vancomycin resistance determinants in Enterococcus spp., clonal structure, and occurrence of VVE using whole-genome sequencing (WGS) in Latvia. Methods: Clinical isolates collected from hospitalised patients in two tertiary-level hospitals in Latvia (2021–2024) were analysed using WGS following routine laboratory identification. Vancomycin resistance determinants were identified in silico, along with MLST and cgMLST genotyping. Results: Of 532 sequenced isolates, 482 met the quality and inclusion criteria. E. faecalis (56.64%) and E. faecium (40.25%) predominated. Among 125 isolates carrying vancomycin resistance genes, vanB (54.40%) was the most frequent, followed by vanA (38.20%) and vanC (6.40%); vanC was restricted to E. gallinarum and E. casseliflavus. Vancomycin resistance was more prevalent in E. faecium (51.03%) than in E. faecalis (6.59%). cgMLST identified outbreak clusters among E. faecium ST80 and ST78 with complex type-specific resistance patterns and hospital specificity. E. faecalis showed polyclonal endemicity with the vanB gene present in different clades. Three (0.62%) vancomycin-variable E. faecium (VVE) isolates were identified in one hospital, harbouring vanA-type gene clusters comprising vanHAX but lacking the sensory gene vanS and the regulatory gene vanR. Conclusions: The VanB gene predominated in both hospitals, driven by clonal expansion of hospital-adapted E. faecium ST80/ST78, contrasting with earlier vanA predominance in Europe but aligning with recent regional vanB trends. The detection of VVE highlights clinically relevant genotype–phenotype discordance, underscoring the importance of integrating genomic surveillance with routine phenotypic testing to detect cryptic resistance and guide effective antimicrobial therapy.

Background: Advanced chronic kidney disease (CKD) and cardiovascular comorbidities frequently coexist in patients with multiple myeloma and are particularly common among hospitalized patients. However, the relationship between common cardiovascular comorbidities and advanced CKD in routine clinical practice remains incompletely characterized. Methods: We conducted a retrospective single-center cohort study including 137 hospitalized patients diagnosed with multiple myeloma between January 2015 and February 2026. Demographic, clinical, and laboratory data were extracted from electronic medical records. Advanced CKD was defined as eGFR < 30 mL/min/1.73 m², calculated using the CKD-EPI 2021 equation. Patients with isolated acute kidney injury were excluded. Cross-sectional associations between cardiovascular comorbidities and advanced CKD were assessed using logistic regression models. Results: The median age was 69 years (IQR 63–77), and 56.9% of patients were women. Renal impairment was common, with a median creatinine level of 2.82 mg/dL and a median eGFR of 22.4 mL/min/1.73 m². Advanced CKD was identified in 55 of 116 patients (47.4%) with available CKD classification. Cardiovascular comorbidities were common, including hypertension (42/55, 76.4%), diabetes mellitus (18/55, 32.7%), myocardial ischemia (41/55, 74.5%), and heart failure (25/55, 45.5%). In univariate analysis, atrial fibrillation showed a significant cross-sectional association with advanced CKD (OR 4.43, 95% CI 1.30–15.07, p = 0.017), as was myocardial ischemia (OR 2.89, 95% CI 1.07–7.80, p = 0.039). In multivariable analysis, atrial fibrillation demonstrated a trend toward an association with advanced CKD but did not remain statistically significant after adjustment. Conclusions: Advanced CKD and cardiovascular comorbidities frequently coexist in hospitalized patients with multiple myeloma. Atrial fibrillation and myocardial ischemia were associated with advanced CKD in univariate analyses; however, these associations were attenuated after multivariable adjustment. Overall, these findings provide insight into the coexistence of advanced CKD and cardiovascular comorbidities in hospitalized patients with multiple myeloma. Full article
