Traumatic nerve injuries involving the distal part of the upper extremity may significantly affect the function of the hand if left untreated. An alternative to nerve autografts for treating digital nerve injuries are nerve transfers. We present the surgical management of a 2.5 cm nerve defect to the proper digital ulnar nerve of the small finger after circular saw injury to the palm of the hand with multiple neurovascular involvement and the use of a non-critical heterodigital nerve transfer for restoration of the critical functional border of the small finger. At 14 months postoperative the sensory recovery grading scale was S4 for the 4th finger and radial border of the 5th finger (primary repair) and S3+ for the ulnar border of the 5th finger (nerve transfer). Donor site morbidity consisted of anesthesia of the ulnar sided tip of the middle finger. Emergency nerve transfer of the proper ulnar digital nerve of the middle finger is a feasible surgical technique for the restoration of the critical ulnar digital border of the small finger after traumatic injuries but with the disadvantage of an insensate donor site.

Objective: Principal component analysis is a powerful dimensionality reduction tool that can uncover hidden patterns in complex biological data. In cellular immunology research, principal component analysis may help identify meaningful relationships between various biomarkers. This study aims to investigate the applicability of principal component analysis for exploring immunometabolic cellular pathways and behaviors in the context of human peripheral blood monocytes.
Methods: This methodological case study analyzed data from 19 healthy young individuals, including body mass index, fasting lipid profiles, and multiparametric flow cytometry of monocyte subsets. Monocytes were classified as classical, intermediate, or nonclassical based on CD14/CD16 expression, and surface markers, cell size, granularity, and intracellular lipid content were assessed. Principal component analysis was performed to explore clusters of correlated parameters and their possible biological significance.
Results: In classical and intermediate monocytes, principal component analysis revealed consistent patterns linking decreased CD14 expression with increased cell size, granularity, and lipid accumulation, reflecting known monocyte maturation processes from CD16– to CD16+. An inverse relationship between body mass index and LDL receptor expression was consistently observed, suggesting metabolic influences on monocyte phenotype. Strong positive loadings for CD11b and CD36 further indicated a link between immune activation and lipid uptake pathways.
Conclusions: This methodological case study demonstrates that principal component analysis can reveal biologically plausible clusters in multiparametric flow cytometry data, offering new perspectives on immunometabolic interactions. While the small sample size limits generalizability, the findings highlight the potential of principal component analysis for hypothesis generation and pathway discovery in immune cell research.

Objective: The study investigated the association between markers of liver steatosis and fibrosis and the adherence to the Mediterranean dietary pattern, evaluated by a diet-quality score, in patients with type 2 diabetes (T2DM) and metabolic dysfunction-associated steatotic liver disease (MASLD).
Methods: Patients with T2DM and MASLD underwent a comprehensive medical evaluation, which included lifestyle, clinical, laboratory, and liver ultrasound assessment. The natural consumption of foods specific to the Mediterranean Diet (MedDiet) was investigated by a previously validated 14-item questionnaire (MedDiet Score). For the estimation of liver steatosis, the Index of NASH (Non-alcoholic steatohepatitis) (ION) was calculated by sex-specific formulas, while liver fibrosis was estimated by the Fibrosis-4 (FIB-4) score.
Results: Data from 271 patients were analyzed. The mean MedDiet Score was 4.55±1.59 points, and most patients scored 3 points (19.93%), 4 points (28.78%), and 5 points (21.40%). Patients with a MedDiet Score ≥5 points had lower fasting blood glucose, ferritin, C-peptide and HOMA-IR, and lower ION values (19.96 ±14.63 vs. 23.50±14.77; p=0.025). No significant differences were noted for FIB-4 values. MedDiet Score was negatively correlated with fasting blood glucose, ferritin, C-peptide, HOMA-IR, and ION values (r=-0.14 [-0.25; -0.01]; p=0.026), and positively with LDL cholesterol levels. Drinking less than one portion of sweet or carbonated beverages daily and eating at least 3 portions of nuts weekly was associated with lower ION values.
Conclusions: Low MedDiet Score was associated with markers of hepatic steatosis (but not fibrosis), worse insulin resistance, higher fasting hyperglycemia, and serum ferritin levels in patients with T2DM and MASLD.

The purpose of the study was to identify the nasal carriage of S. aureus in healthcare workers of the clinical wards of the Târgu-Mureș Emergency County Hospital and to characterize the bacterial isolates phenotypically and genotypically. This study included 64 medical staff from the Târgu-Mureș Emergency County Hospital. Their data and nasal exudates were collected. The multiplex PCR method was used to identify femA, PVL, mecA, eta, etb and tst genes. ERIC-PCR was used to evaluate the genetic similarity of the bacterial isolates. A prevalence of 25% of nasal carriage of S. aureus was obtained. Of these 12% were methicillin-resistant and 47% showed clindamycin-inducible resistance phenotype. Almost half of the isolates (47%) were from ICU (Intensive Care Unit) personnel. PCR results confirmed the species and the presence of the mecA gene in MRSA (Methicillin-Resistant Staphylococcus aureus) isolates. Except for 4 strains that showed the gene for exfoliatin A, no other virulence factor genes were detected. ERIC-PCR identified the partially common origin of the S. aureus strains, all having a similarity of 55%, with some reaching up to 100% similarity. Although the strains did not spread clonally and did not carry important virulence factors, there were associations between the nasal carriage and respiratory infections, previous diagnosis with S. aureus, Intensive Care Units and Nephrology wards.

Objective: The present study aimed to assess the prevalence of diabetes in a cohort of pheochromocytoma patients registered at the Pathology Departments of two County Hospitals. Additionally, diabetes status was re-evaluated following tumor resection to determine whether surgery had an impact on improving or alleviating the condition.
Methods: We performed a retrospective study including all patients who underwent adrenalectomy and were diagnosed with pheochromocytoma based on histopathological findings in Mureș County (2017-2022) Hospital and Mureș County Emergency (2000-2022), Romania, respectively. All patients that were alive and whose contact details were available, participated in a phone survey and provided clinical data. Information on the presence of diabetes at the time of pheochromocytoma diagnosis and their diabetes status after tumor resection was recorded. The follow-up period ranged from 24 to 216 months.
Results: We identified 35 patients with a histopathological diagnosis of pheochromocytoma. Complete histopathological and clinical data were obtained for 23 patients; 13/23 (56.5%) were women and 10/23 (43.59%) were men; the mean age at surgery was 52.73 ±14.22 years-old (range 24-78). Of these, eight patients (n=8/23; 34.7%) were diagnosed with diabetes prior to surgery. All diabetic patients showed improvements in their carbohydrate metabolism and 5 (62.5%) of them revealed a restored normal glucose tolerance after surgery.
Conclusions: Our study highlights that overt diabetes mellitus is present in more than one-third of patients with pheochromocytoma. Tumor removal improves dysglycemia in all diabetic pheochromocytoma patients and cures diabetes in a significant proportion of them.

Management of pheochromocytoma, particularly in the perioperative period, requires a tailored pharmacological approach to address hemodynamic instability and hypertensive crises. This review evaluates the safety, efficacy, and clinical context of esmolol, nicardipine, and sodium nitroprusside in managing blood pressure and heart rate during pheochromocytoma resection. Esmolol, an ultra-short-acting β1-adrenergic antagonist, is essential in controlling tachyarrhythmias and myocardial stress in the perioperative period. Its rapid onset and short half-life enable precise titration, though continuous monitoring is required to mitigate the risk of bradycardia and hypotension. Nicardipine, a dihydropyridine calcium channel blocker, is effective in controlling acute hypertensive episodes and maintaining coronary perfusion. Its selectivity for vascular smooth muscle makes it an ideal agent for patients with low ejection fraction, minimizing cardiac depression. In contrast, sodium nitroprusside, a direct nitric oxide donor, provides immediate and reversible vasodilation, which is crucial for managing hypertensive crises during surgery. However, its use necessitates close monitoring due to the risk of cyanide and thiocyanate toxicity with prolonged use.
Choosing the most appropriate antihypertensive therapy depends on patient-specific factors such as comorbidities and the severity of hemodynamic changes. Each medication’s therapeutic effect, side effects, and risk profiles should be carefully considered to optimize clinical outcomes in high-risk patients undergoing pheochromocytoma surgery. This review highlights the importance of understanding the pharmacodynamics and appropriate use of these agents in clinical practice to improve patient management and outcomes.

Objective: The study aimed to evaluate the lifestyle and dietary habit changes among students enrolled in the Nutrition and Dietetics program at the George Emil Palade University of Medicine, Pharmacy, Science, and Technology of Târgu Mureș. Specifically, we examined the influence of academic progression on stress levels, dietary choices, purchasing habits, and physical activity.
Methods: A cross-sectional questionnaire-based pilot study was conducted among 55 Nutrition and Dietetics students across different academic years. Data were collected using a structured questionnaire assessing dietary habits, lifestyle factors, and stress levels. The responses were analyzed for trends across academic years and body mass index categories, with statistical comparisons performed to determine significant differences.
Results: Final-year students demonstrated healthier dietary habits, increased water consumption, and more fruit and vegetable intake compared to their younger peers, while also exhibiting higher stress levels. Differences in nutritional behaviors were also observed based on BMI categories, with normal-weight students more likely to adopt healthier eating patterns. An overall increased dietary awareness was observed, which was correlated with the accumulated nutritional knowledge.
Conclusions: The findings suggest that formal education in nutrition plays a significant role in shaping healthier behavior. However, challenges remain regarding stress management, physical activity, and unhealthy dietary habits. Targeted interventions and institutional policies may be beneficial in supporting sustainable lifestyle changes among students.
