Abstract Introduction: Co-occurrence of multiple systemic diseases, particularly in late presenters, can obscure diagnosis and delay appropriate treatment. This work aims to highlight the complex clinical presentation, diagnostic and treatment challenges of a late presenter with new human immunodeficiency virus infection, complicated by Salmonella sepsis, oropharyngeal candidiasis, and Cytomegalovirus meningo-encephalitis, as well as the importance of a comprehensive diagnostic approach in immunocompromised patients with polymorphic symptoms. Material and Methods: We report the case of a 43-year-old male who presented with systemic symptoms, including fever, wasting syndrome, urinary and neurological complaints. Clinical, microbiological, imaging, and molecular diagnostic tools were used to evaluate the patient. Diagnostic investigations included blood and urine cultures, human immunodeficiency virus and syphilis serology, cerebrospinal fluid analysis via molecular detection tools, and imaging studies. Results: The patient was diagnosed with Human Immunodeficiency Virus-1 infection, Salmonella enterica group B sepsis emerging from a urinary infection, oropharyngeal and esophageal Candidiasis, and cytomegalovirus meningoencephalitis confirmed via polymerase chain reaction testing of cerebrospinal fluid. He was treated with a combination of antibacterial (Ceftriaxone), antifungal (Fluconazole), and antiviral therapy (Ganciclovir/Valganciclovir), alongside supportive care and initiation of antiretroviral therapy. After 29 days of hospitalization, he exhibited notable clinical improvement, including weight gain, neurological recovery, and resolution of oropharyngeal lesions. Conclusions: This case illustrates the diagnostic and therapeutic complexity of managing patients with advanced Human Immunodeficiency Virus infection and multiple opportunistic complications. The prompt use of diagnostic tools, a multidisciplinary approach, and the staged initiation of antiretroviral therapy were fundamental for achieving favorable outcomes. Early recognition of late presenters remains essential to prevent life-threatening complications.

Abstract Smoking cessation counseling is a critical component of healthcare education, yet the effectiveness of different role-play-based learning approaches remains insufficiently investigated. The objective of this scoping review is to systematically map the existing evidence on the use of role-play-based learning approaches—including standardized patients, virtual patients, and other simulation methods—for training healthcare students and professionals in smoking cessation counseling. The review will follow the methodology for scoping reviews. Searches will be conducted in PubMed, Scopus, Web of Science, ERIC, IEEE Xplore for peer-reviewed English-language articles involving healthcare students or professionals, role-play-based learning approaches addressing tobacco cessation. Two reviewers will independently screen and chart the data. Findings will be presented through summary tables outlining intervention characteristics, target populations, educational settings, and outcomes, complemented by narrative descriptions highlighting key benefits, limitations, and implementation factors. Additionally, thematic mapping will be used to synthesize insights relevant to the development of virtual patient applications. The results will be disseminated through peer-reviewed publication and conference presentations.

Abstract Background: Hepatitis B virus (HBV) infections cause approximately 1.2 million deaths annually, mainly due to complications such as hepatocellular carcinoma and cirrhosis. The key marker used to monitor HBV viraemia and guide treatment is the viral load, often unavailable in resource-limited settings. This study aimed to identify surrogate markers predicting hepatitis viral activity, valuable in areas with limited access to molecular diagnostics. Methods: A retrospective observational study of 178 chronic hepatitis B patients was conducted at Târgu Mureș Clinical County Hospital between April 2022 and April 2025. The dataset included demographic data, hepatitis B viral load, serological viral markers, blood counts, liver function tests and coagulation parameters. Exclusion criteria consisted of duplicate samples, as well as those with detectable viral loads but missing laboratory determinations. Univariable logistic regression was used to assess associations between abnormal serological parameters and the odds of viral DNA detectability. Results: Altogether, 178 samples tested for hepatitis viral load were included in the final analysis. Detectable viral DNA was found in 64 (35.96%) patients. A viral load positivity was significantly associated with positive HBsAg (OR = 41.7, 95% CI: 5.50-315.70, p<0.0001), elevated AST levels (OR = 2.46, 95% CI:1.23-4.92, p=0.01), and negative HBeAb (OR = 0.3, 95% CI: 0.09-0.94, p=0.04). Other tested associations were not statistically significant. Conclusion: HBsAg, HBeAb, and AST levels were significantly associated with hepatitis B DNA detectability, highlighting their potential use in settings lacking molecular assays. Further research with larger cohorts may help identify accessible predictors of viral replication and disease progression.

Abstract Background: Acute heart failure (AHF) is frequently complicated by renal dysfunction, leading to cardiorenal syndrome (CRS), and poses significant management challenges. Objective: This study aimed to elucidate the interrelationships between cardiac function, renal impairment and key biomarkers: high-sensitivity troponin T (hs-Troponin T) and N-terminal pro-brain natriuretic peptide (NT-proBNP), in patients with AHF with and without CRS. Methods: In this prospective observational study, 60 adult patients admitted with AHF were stratified into two groups based on renal function. Baseline clinical data, laboratory measurements, and echocardiographic assessments were performed within 48 h of admission. Results: Patients with CRS exhibited a significantly lower left ventricular ejection fraction (34.73 ± 2.49% vs. 41.70 ± 5.08%, p<0.001), elevated serum creatinine levels, and a more deranged lipid profile than patients with AHF alone. Both hs-Troponin T and NT-proBNP levels were markedly higher in the CRS group, with significant inverse correlations between these biomarkers and the ejection fraction. Multivariate analysis revealed that elevated NT-proBNP levels (OR 9.465, p<0.01) were strong predictors of prolonged hospitalization. Conclusion: These findings highlight the complex interplay between cardiac and renal dysfunction in patients with AHF. Elevated levels of hs-troponin T and NT-proBNP, particularly NT-proBNP, underscore their potential as valuable diagnostic and prognostic tools for early risk stratification and management in high-risk patients.

Abstract 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.

Abstract Wilson disease is a disorder of copper metabolism caused by genetic mutations in the ATP7B gene which lead to the accumulation of copper in the body. This study was conducted using an online questionnaire consisting of 32 questions in a group of patients suffering from Wilson disease. The study included 67 people aged 7 to 56 with Wilson disease. The most common symptoms of the participants were hepatic and neurological in 22 cases (32.8%). The most common neurological symptom in the assessed cases was muscle stiffness (49.5%), followed by tremor (45%), and speech disorders (40.5%). The Kayser-Fleischer ring was present in 50.7% of the participants. The most commonly used drug treatment in the participants was D-penicillamine (77.61%).

Abstract Introduction: Methotrexate is often used as the first line of systemic treatment in patients with moderate to severe psoriasis and psoriatic arthritis. Case report: We present the case of a 44-year-old male patient with moderate plaque psoriasis who was treated with Methotrexate and diagnosed with mild hepatic steatosis during the first month of treatment. Using FIB-4 (Fibrosis Index Based on 4 factors) as a noninvasive method for assessing the risk of liver fibrosis, the patient was able to take Methotrexate safely, with close monitoring of liver function. Conclusions: FIB-4 can be used to assess the risk of liver fibrosis in psoriasis patients treated with Methotrexate to ensure better adherence to the treatment.

Abstract 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 Mureş County (2017-2022) Hospital and Mureş 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.

Abstract Objective: This article intends to illustrate the clinical qualification of the Vivano Negative Pressure Wound Therapy system through a detailed case study involving a patient with post-abdominoplasty wound complications. Methods: A 35-year-old female patient presented with wound dehiscence, necrosis, and infection following cosmetic abdominoplasty performed abroad. After initial conservative management failed, surgical debridement and repeated application of Vivano Negative Pressure Wound Therapy at varying pressure settings led to rapid granulation tissue development, infection control, and successful integration of a split-thickness skin graft. Its role in supporting graft adherence was especially critical, culminating in complete wound closure and recovery within a four-week inpatient period. Results: The use of Vivano Negative Pressure Wound Therapy contributed considerably to wound stabilization, bacterial clearance, and post-grafting support, leading to complete wound healing and hospital discharge within four weeks of active intervention. Conclusion: This case underscores the value of Vivano Negative Pressure Wound Therapy in managing complex post-operative wounds, commencement of treatment using this device results in a significantly faster rate of wound healing compared to standard care.

Abstract 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 general-izability, the findings highlight the potential of principal component analysis for hypothesis generation and pathway discovery in immune cell research.
