Background: Left lateral tilt is traditionally recommended during cesarean delivery to reduce aortocaval compression and maintain maternal hemodynamic stability; however, with the widespread adoption of prophylactic vasopressor strategies recommended by current guidelines, the incremental benefit of routine tilt remains uncertain. Methods: We conducted a prospective, nonrandomized observational comparative study at the University Hospital Bratislava including 99 women undergoing elective cesarean delivery under spinal anesthesia. Participants were managed either with a standard ~15° left lateral tilt (n = 41) or in a flat supine position without tilt (n = 58), according to the day of surgery and routine anesthesiologist practice; all other anesthetic and surgical procedures were identical. A prophylactic norepinephrine infusion was initiated at 0.05 µg/kg/min and titrated to maintain systolic arterial pressure at 90–100% of baseline. The primary outcome was the average norepinephrine infusion rate (µg/kg/min) from induction of spinal anesthesia to neonatal delivery. Secondary outcomes included total norepinephrine dose to delivery, dose normalized per kilogram, and neonatal outcomes (Apgar scores and umbilical arterial blood gas parameters). Results: The median norepinephrine infusion rate was 0.03 µg/kg/min in both groups (tilt: IQR 0.01–0.04 vs. no-tilt: IQR 0.02–0.04; p = 0.325). Total norepinephrine dose to delivery (20 [15–30] µg vs. 25 [15–35] µg; p = 0.89) and dose per kilogram (0.25 [0.15–0.33] µg/kg vs. 0.34 [0.17–0.44] µg/kg; p = 0.10) were also comparable. Neonatal outcomes, including Apgar scores and umbilical arterial blood gas parameters, did not differ significantly between groups. In a multivariable regression sensitivity analysis adjusting for maternal and procedural covariates, table tilt was not independently associated with norepinephrine requirements. Conclusions: In parturients undergoing cesarean delivery under spinal anesthesia with prophylactic norepinephrine infusion, a 15° left lateral tilt did not reduce vasopressor requirements or improve neonatal outcomes. Routine maternal tilt therefore appears unnecessary for hemodynamic optimization in this setting, and patient positioning can be individualized without compromising maternal or neonatal safety.

Background/Objectives: Depression is a serious mental illness worldwide, with a continuously increasing prevalence. As evidence supporting forest therapy as a non-pharmacological intervention has accumulated, the need for collaboration between the medical and forest therapy sectors has emerged; however, practical tools applicable in real-world clinical settings remain limited. This study aimed to derive components of a diagnostic assessment sheet to support clinicians in developing personalized forest therapy programs for patients with depression. Methods: Program-related literature and case materials from diverse disciplines were systematically analyzed to identify transferable program development elements and therapeutic activities. Based on these findings, a two-round Delphi survey was conducted with 17 experts in forest therapy and medicine. Results: Through the Delphi process, 26 therapeutic activities were identified and classified into six final activity types. Assessment items were developed to support clinicians in selecting appropriate activity types, and nine key precaution items were identified to enhance safety and appropriateness during program design and implementation. Conclusions: This study provides a structured framework to guide clinicians and forest therapy instructors in composing individualized forest therapy programs for patients with depression, supporting practical medical–forest therapy integration. Future research should validate the diagnostic assessment sheet through empirical field testing.

Background/Objectives: Contrast-induced nephropathy (CIN) is a common iatrogenic or medically induced condition among patients who receive intravenous infusion of iodinated contrast media that can cause renal insufficiency, raise the cost of care, and increase mortality risk. This study evaluated the incidence of CIN and predictors of renal function among cancer patients receiving contrast-enhanced computed tomography (CECT). Methods: A prospective, single-center longitudinal study was conducted at King Abdul-Aziz Medical City’s (Jeddah) medical imaging department from December 2021 to December 2023. Convenience sampling was used to select patients who were exposed to CECT based on data filled in the electronic medical record during the study period. Results: The final sample constituted 80 patients (47.71% attrition, mean age = 55.5 years, 58.75% male). The high attrition rate was associated with participants with incomplete records, those who were lost to follow-up, and those whose follow-up Scr was collected after 72 h from CECT administration. There was no statistically significant change in Scr following contrast exposure (mean increase 0.9 µmol/L; paired t = 1.41, p = 0.162; Wilcoxon p = 0.326). The incidence of CIN was 3.75% (3 of 80 patients; 95% confidence intervals (CI), 1.28–10.39%). Regression analysis showed no statistically significant associations between the percentage change in Scr and age, sex, baseline creatinine, or eGFR category (model R² = 0.07). No clinically meaningful predictors of CIN were identified. Conclusions: The incidence of CIN in this study’s cohort of low-risk cancer patients undergoing CECT was low, and contrast exposure did not produce significant short-term changes in renal function. These findings support the safety of modern contrast agents in oncology imaging, but multi-center studies with larger samples and more robust methods are warranted to refine CIN risk assessment in cancer patients undergoing CECT.
