Retatrutide (LY3437943) is an investigational, once-weekly, lipidated 39-residue peptide that activates the glucose-dependent insulinotropic polypeptide, glucagon-like peptide-1, and glucagon receptors. Its molecular design combines incretin activity with glucagon receptor engagement while maintaining glycaemic efficacy. This critical narrative review examines molecular engineering, pharmacokinetics, dose escalation, pharmaceutical development, and clinical evidence available through 11 September 2026. Five phase 3 trials have reported positive primary outcomes, but only TRANSCEND-T2D-1 has a full peer-reviewed report; the obesity trials are currently available as sponsor topline disclosures. In those disclosures, efficacy-estimand mean weight reductions of 28.3% at 80 weeks (TRIUMPH-1) and 28.7% at 68 weeks (TRIUMPH-4) were reported, with a TRIUMPH-1 treatment-regimen estimate of 25.0%; these values remain provisional pending full published trial reports. The peer-reviewed TRANSCEND-T2D-1 report supports glycaemic efficacy in early type 2 diabetes. Interpretation requires attention to estimands, population differences, treatment discontinuation and selection into trial extensions. Gastrointestinal adverse events, dysaesthesia, heart-rate changes and the functional consequences of lean-mass loss require further evaluation. Pharmaceutical priorities include scalable synthesis, impurity and potency control, formulation stability, immunogenicity and reliable dose delivery. Retatrutide provides a clinically advanced example of unimolecular poly-agonism, but comparative effectiveness, long-term outcomes and regulatory review remain essential to defining its therapeutic role.

Background and Objectives: Adolescent pregnancy is associated with biological, behavioral, and healthcare-related vulnerabilities that are incompletely captured by structured datasets. This study aimed to characterize selected maternal vulnerability indicators derived from narrative clinical documentation and to examine their exploratory associations with documented prenatal care deficiency and neonatal outcomes. Materials and Methods: We conducted a retrospective cohort study including 759 singleton adolescent pregnancies managed at a Romanian secondary obstetric center between 2020 and 2024. Narrative clinical observations were reviewed to extract maternal vulnerability indicators, including smoking, anemia, infection, hypertensive disorders, obesity, Rh incompatibility, and documented prenatal care deficiency. Associations between extracted variables, documented prenatal care deficiency, and neonatal outcomes were evaluated using contingency analyses, Kendall’s tau-b correlations, and multivariable logistic regression models. Results: Among pregnancies with available narrative observations, documented prenatal care deficiency was identified in 612/692 (88.4%), maternal anemia in 207/692 (29.9%), and smoking during pregnancy in 186/692 (26.9%). Validation performance differed across categories, with a sensitivity of 57.1% (95% CI 18.4–90.1%) for hypertensive disorders and wide confidence intervals for rare categories. Correlations between extracted variables were weak, indicating limited clustering of maternal risk factors. Hypertensive disorders (aOR 0.31, 95% CI 0.10–0.95, p = 0.038) and maternal obesity (aOR 0.39, 95% CI 0.16–0.98, p = 0.044) were associated with lower odds of documented prenatal care deficiency. Significant neonatal associations were observed primarily for low birth weight. Hypertensive disorders were independently associated with increased odds of low birth weight (aOR 3.56, 95% CI 1.33–9.54, p = 0.011), whereas documented maternal anemia was associated with lower observed odds of LBW (aOR 0.45, 95% CI 0.24–0.82, p = 0.009). No significant associations were identified for preterm birth or Apgar score < 7 at 5 min. Conclusions: Narrative clinical documentation allowed the identification of heterogeneous maternal vulnerability indicators that showed weak interrelationships and selective associations with prenatal surveillance patterns and low birth weight. These exploratory findings should be interpreted in the context of healthcare engagement and documentation practices.

Background/Objectives: Adolescent pregnancy is associated with an increased risk of adverse neonatal outcomes, including low birth weight, preterm birth, and impaired neonatal adaptation. While maternal age is a well-established determinant, the independent role of parity in this population remains uncertain. This study aimed to assess the association between parity and neonatal outcomes in adolescent mothers. Methods: We conducted a retrospective cohort study including 751 singleton live-birth deliveries to adolescent mothers aged p = 0.622), Apgar score < 7 at 5 min, or the composite adverse neonatal outcome. Maternal age < 15 years and gestational age were independently associated with Apgar score < 7 at 5 min. Multiparity was associated with lower odds of low birth weight (aOR 0.40, 95% CI 0.17–0.92, p = 0.031). Conclusions: Parity was not independently associated with most neonatal outcomes in adolescent pregnancies. Multiparity was associated with lower odds of low birth weight, but this finding should be interpreted cautiously because residual confounding cannot be excluded.

(1) Background: Antibiotic co-administration during COVID-19 hospitalization is common, but evidence supporting routine use without confirmed bacterial co-infection is limited, and the impact on post-COVID recovery remains largely uninvestigated; (2) Methods: Single-center prospective observational cohort of 127 hospitalized COVID-19 adults (March 2020–December 2024) across four pandemic waves. Antibiotic exposure was the primary variable. Endpoints were 30-day mortality, ICU admission, and persistent dyspnea at three months. Multivariable logistic regression with Firth’s penalized profile likelihood 95% CI was performed; ROC analysis assessed procalcitonin (PCT) discrimination; (3) Results: Of 127 patients (median age 70.3 years; 63.8% male; 61.4% unvaccinated), 68 (53.5%) received antibiotics. Notably, 61.5% of patients with PCT ≤ 0.25 ng/mL (viral etiology likely) received antibiotics. After adjustment, antibiotic use was not independently associated with 30-day mortality (OR 0.98, 95% CI 0.27–4.05), ICU admission (OR 1.12, 95% CI 0.31–4.05), or persistent dyspnea at three months (OR 1.51, 95% CI 0.62–4.16). COVID-19 severity was the sole independent mortality predictor (OR 3.563, p = 0.018). At three months, 35.6% reported persistent dyspnea and 14.4% had CT pulmonary fibrosis; (4) Conclusions: Antibiotic exposure did not independently predict short- or long-term outcomes after adjustment for severity, while prescribing was misaligned with PCT-based bacterial probability—supporting biomarker-guided stewardship in epidemic respiratory disease.

Post-acute sequelae of SARS-CoV-2 infection (PASC) extend well beyond the acute respiratory phase, with accumulating virological evidence that SARS-CoV-2 RNA, viral antigens, and proteolytic fragments may persist in cardiovascular and other extrapulmonary tissues, although the extent to which such detection represents replication-competent reservoirs versus residual viral material with uncertain pathological relevance remains under active investigation. Sudden cardiac death (SCD) and fatal pulmonary thromboembolism (PTE) have emerged as forensically and epidemiologically significant outcomes in individuals with prior infection, situated at the intersection of microbiology, public health, and forensic medicine. To synthesize current evidence on the virological mechanisms by which SARS-CoV-2 may contribute to post-acute sudden cardiac death (SCD) and pulmonary thromboembolism (PTE), the population-level epidemiology of these outcomes, and their implications for public health surveillance and forensic practice, we conducted a narrative review of PubMed (MEDLINE), Scopus, and Web of Science Core Collection. The search covered publications from January 2020 to December 2025 and focused on SARS-CoV-2 cellular tropism and tissue persistence, immune-mediated and thromboinflammatory mechanisms, excess cardiovascular and thromboembolic mortality, and autopsy-based pathological findings. After de-duplication of 1837 initially identified records (412 duplicates removed) and screening of 1425 unique records, 78 studies were retained for final synthesis based on virological, epidemiological, and forensic relevance. SARS-CoV-2 enters cardiomyocytes, pericytes, and vascular endothelial cells through ACE2-dependent mechanisms, with cathepsin L compensating for the limited cardiac expression of TMPRSS2. Viral RNA and antigen have been detected in cardiovascular and other extrapulmonary tissues months after symptom onset in selected autopsy series, although persistent detection of viral components does not necessarily indicate ongoing productive infection or direct tissue injury. Endothelial dysfunction, neutrophil extracellular trap (NET) formation, complement activation, and persistent thromboinflammation have been proposed as plausible mechanistic substrates for arrhythmogenic remodelling and thromboembolic events, although definitive causal pathways remain incompletely understood. Population-based studies document persistent excess cardiovascular mortality across multiple jurisdictions, with hazard ratios for pulmonary embolism remaining elevated months after acute infection, particularly in unvaccinated individuals. Autopsy series identify mixed pathological patterns including focal lymphocytic infiltrates, microvascular thrombosis, contraction-band necrosis, and cardiomyocyte vacuolation, although fulminant lymphocytic myocarditis fulfilling Dallas criteria remains uncommon. A microbiology-informed framework uniting tissue-based viral detection, standardized cardiac and pulmonary sampling protocols, and prospective post-mortem registries is needed to better characterize the potential contribution of SARS-CoV-2 to post-acute cardiovascular mortality and to support cause-of-death certification, public health surveillance, and medicolegal practice in the post-pandemic era. Many of the proposed mechanisms remain under active investigation, and definitive causal relationships between viral persistence and adverse cardiovascular outcomes have not yet been conclusively established.

Background and Objectives: Adolescent pregnancy is traditionally associated with increased obstetric risk, particularly among very young adolescents. Romania continues to report one of the highest adolescent birth rates in the European Union, yet age-stratified clinical data on obstetric outcomes among minors remain limited. This study aimed to evaluate maternal and intrapartum outcomes among underage mothers (Materials and Methods: We conducted a retrospective cohort study of all live births and stillbirths among mothers aged 12–17 years recorded between 2020 and 2024 at a secondary maternity hospital in Romania. Data were extracted from standardized obstetric and neonatal records. Primary outcomes included preterm birth (2 test. Multivariable logistic regression models were used to assess independent associations between maternal age and obstetric outcomes. Results: The cohort comprised 763 adolescent mothers aged 12–17 years. No significant differences were observed across age groups in gestational age at birth, preterm birth rate, fetal presentation, or mode of delivery. In multivariable analyses, younger maternal age was not independently associated with preterm birth (adjusted odds ratios [aORs] 0.87–1.21) or cesarean delivery (aORs 0.74–1.08). Obstetric factors, such as non-cephalic presentation and characteristics of membrane rupture, were the main predictors of adverse outcomes. Temporal analyses demonstrated stable outcome patterns across the study period, with no significant interaction between maternal age and year of delivery. Conclusions: In this tertiary-care cohort, very young maternal age (<15 years) was not associated with poorer obstetric outcomes compared with older adolescents. These findings suggest that standardized antenatal surveillance and intrapartum management may mitigate age-related obstetric risk among underage mothers. Further population-based studies are warranted to contextualize these results within broader healthcare access and social determinants of adolescent pregnancy. Cesarean section rates were high across all groups (~50%), with no significant differences by maternal age.

Evidence on hospitalised COVID-19 patients during the Omicron BA.5 wave from Eastern European, vaccine-heterogeneous cohorts remains limited. We conducted a retrospective single-centre cohort study of 395 consecutive adults admitted with laboratory-confirmed COVID-19 to a tertiary infectious-diseases unit in western Romania between 1 July and 31 October 2022. Median age was 72 years (IQR 65–81); 33.2% were unvaccinated, 42.8% had documented prior SARS-CoV-2 infection, and 41.3% were obese. Multivariable logistic regression identified independent predictors of in-hospital mortality and post-acute symptom burden. In-hospital mortality was 15.7% (62/395). Vaccination was independently associated with lower mortality (adjusted odds ratio [aOR] 0.55, 95% CI 0.30–0.99; p = 0.048), as was each 1% increase in admission SpO₂ (aOR 0.83, 95% CI 0.76–0.92; p < 0.001), whereas COPD independently increased mortality risk (aOR 2.42, 95% CI 1.15–5.10; p = 0.020). Interleukin-6 was the most discriminating admission biomarker for in-hospital mortality (AUROC 0.70). Bloodstream bacterial co-infection, detected in 22.5% of patients tested on clinical suspicion, was dominated by gut-derived organisms with case-fatality ≥30%. At discharge, 90.1% reported persistent symptoms, most commonly cognitive (24.6%). Prior SARS-CoV-2 infection independently predicted post-acute symptom burden (aOR 2.96, 95% CI 1.75–5.01; p < 0.001), with a specific cardiopulmonary signature. In this BA.5 cohort, vaccination remained protective; IL-6 was the most informative admission biomarker; bloodstream infections suggested gut translocation; and prior infection was an independent determinant of early post-acute symptom burden.

Background/Objectives: Psychiatric inpatient care varies substantially in its clinical goals, resource demands, and financial implications. Acute units focus on short-term crisis stabilization, whereas chronic units provide prolonged supervision for patients with persistent functional impairment. Limited evidence exists from Eastern Europe on how these differing service models impact both hospital costs and clinical outcomes such as early rehospitalization. This study aimed to compare the economic and operational performance of Acute versus Chronic Psychiatry and to identify predictors of 30-day readmission following acute psychiatric hospitalization. Methods: This retrospective observational study analyzed routinely collected data from a Romanian public hospital. All adult admissions to Acute and Chronic Psychiatry recorded between 1 January 2024 and 31 December 2024 were included. Standardized financial indicators were derived from administrative data, while clinical variables and readmission outcomes were extracted from electronic medical records. Between-group comparisons of economic and operational indicators were performed using t-tests. Multivariable logistic regression was used to determine independent predictors of 30-day readmission in Acute Psychiatry, reporting adjusted odds ratios (aOR) with 95% confidence intervals (CI). Model performance was evaluated with area under the curve (AUC), Hosmer–Lemeshow tests, and Nagelkerke R². Results: Acute Psychiatry demonstrated significantly higher mean cost per bed-day (798.76 vs. 373.75 lei; p < 0.001), but a lower mean cost per patient due to shorter hospitalization (10.17 vs. 53.32 days). A total of 188 acute patients (13.7%) were readmitted within 30 days. No early readmissions occurred in Chronic Psychiatry, consistent with its long-stay care model. Independent predictors of readmission included psychotic disorder diagnosis (aOR = 1.62, 95% CI: 1.18–2.23), multiple prior admissions (aOR = 1.35, 95% CI: 1.18–1.54), shorter length of stay (LOS) (aOR = 0.88 per 5-day increase, p = 0.006), and absence of a post-discharge plan (aOR = 0.54, 95% CI: 0.39–0.76). Model discrimination was acceptable (AUC = 0.74). Conclusions: Acute and chronic psychiatric services differ markedly in cost structures and care pathways. Early rehospitalization is a clinically relevant outcome within acute psychiatric care and is influenced by both patient-level and continuity-of-care factors. Enhancing discharge coordination, expanding continuity-of-care strategies, and optimizing resource allocation toward community-based support may reduce early rehospitalizations while improving hospital cost-efficiency.

Background and Objectives: Access to anterior cruciate ligament reconstruction (ACLR) varies substantially across health systems, yet national-level data from Eastern Europe remain limited. This study provides the first nationwide, regionally stratified assessment of ACLR activity in Romania, examining geographic variation, socioeconomic and workforce determinants, and inequality. Materials and Methods: We conducted a retrospective cross-sectional analysis of all ACLRs reported in the national administrative hospital database (2017–2023), supplemented with demographic, GDP, and workforce statistics. Outomes included incidence per 100,000 population, private-sector share, and sex distribution. Regional differences were tested using Kruskal–Wallis and Dunn post hoc comparisons. Predictors of ACLR incidence and private-sector utilization were identified through multivariable Poisson and logistic models. Inequality metrics (Gini coefficients, P90/P10 ratios) and sensitivity analyses excluding Bucharest–Ilfov were also performed. Results: A total of 11, 080 ACLRs were recorded. Incidence varied markedly across regions, from a median of 40.0 per 100,000 in Bucharest–Ilfov to p < 0.001). Higher GDP per capita correlated with incidence (ρ = 0.36) and explained 45% of its variance. Private-sector involvement ranged from p < 0.001). Private-sector access was primarily determined by the proportion of private orthopedic surgeons (OR 21.03). National inequality was extreme (Gini 0.842–0.752; P90/P10 > 10⁹), reflecting the concentration of procedures within a small number of counties. Results were consistent across sensitivity analyses. Conclusions: ACLR in Romania displays severe territorial inequities driven by socioeconomic development, workforce distribution, and uneven private-sector capacity. Targeted regional investment and coordinated workforce strategies are necessary to improve equitable access to surgical care.

Arthroscopic knee surgery represents a cornerstone of modern orthopedic practice, yet nationwide data from Eastern Europe remain scarce. This study provides the first comprehensive assessment of arthroscopic knee procedures in Romania over a seven-year period (2017–2023), focusing on anterior cruciate ligament (ACL) reconstruction trends and related interventions. Using national hospital discharge data, all arthroscopic knee procedures were identified and analyzed by year, sex, age group, region, and hospital type. A total of 76,804 procedures were recorded, including 26,888 reconstructions (O15301/O15303) and 29,979 meniscectomies (O13404). ACL reconstructions increased from 1560 cases in 2017 (7.9/100,000 inhabitants) to 1865 in 2023 (9.8/100 k), with a marked decline in 2020 (5.3/100 k) due to the COVID-19 pandemic and full recovery thereafter. Men predominated in ACL reconstructions (74%; 8226 males vs. 2854 females), whereas meniscectomy peaked in middle-aged adults (50–54 years: 48.7/100 k). Surgical activity was highly centralized, with five counties performing over two-thirds of all ACL reconstructions. Approximately 89% of procedures were conducted in public hospitals. These findings reveal substantial progress but also persistent regional and demographic inequities. Strengthening access, standardizing indications for degenerative meniscal surgery, and establishing a national ACL registry could support equitable, evidence-based advancement of arthroscopic care in Romania.
