Background and Objectives: Vitamin D deficiency and psychological distress have been linked to cancer biology, but their relevance to tumor differentiation in head-and-neck squamous cell carcinoma (HNSCC) is uncertain. Materials and Methods: In this cross-sectional study at the Department of Otolaryngology, County Hospital of Timișoara, Romania, we enrolled newly diagnosed HNC patients from October 2023 to December 2024, analyzing 199 SCC patients after exclusions. Vitamin D status was assessed using serum 25-OH-vitamin D levels, and distress was measured with the validated Romanian version of the Hospital Anxiety and Depression Scale (HADS). Tumor aggressiveness was defined by histological grade (G3 vs. G1–G2). Univariate, multivariate, and subgroup analyses were conducted, adjusting for confounders like smoking. Results: Vitamin D deficiency (<20 ng/mL) was prevalent (80.40%), with median 25-OH-vitamin D levels of 15.1 ng/mL. Univariate analysis revealed a modest association between vitamin D deficiency and poorly differentiated tumors (G3 vs. G1–G2; OR = 1.79, p = 0.055) and between clinically significant anxiety (HADS-A ≥ 8) and G3 tumors (OR = 1.71, p = 0.059). A weak negative correlation was observed between 25-OH-vitamin D levels and HADS-A scores (rho = −0.17, p = 0.052). In multivariate analysis adjusted for age, smoking, and tumor location, these associations weakened (vitamin D deficiency: OR = 1.55, p = 0.082; HADS-A ≥8: OR = 1.56, p = 0.113). Subgroup analysis suggested a trend toward higher odds of G3 tumors in patients with both vitamin D deficiency and high anxiety (OR = 1.72, p = 0.075). Conclusions: Univariate analyses indicated potential links between vitamin D deficiency, psychological distress, and tumor aggressiveness in HNSCC, but these did not reach statistical significance after adjustment for confounders. The observed trends, particularly in subgroups with combined deficiency and distress, suggest a possible interplay worth exploring further. To conclude, neither vitamin-D deficiency nor clinically significant distress independently predicted poor histological differentiation after adjustment; observed trends, including a possible distress–vitamin-D interaction, are hypothesis-generating and warrant testing in larger, longitudinal cohorts.

Dysphagia is a frequent and potentially life-threatening complication in patients with neurological disorders. Swallowing is a complex neurophysiological mechanism regulated by a widespread network of central nervous system regions. The control of swallowing functions requires the integrity of the central pattern generator located in the brainstem, the sensorimotor cortex, the basal ganglia, and the cerebellum, but also peripheral nerves and swallowing muscles. Neurological diseases affecting either central or peripheral components of this system commonly result in dysphagia. Despite its clinical relevance, the management of neurogenic dysphagia remains challenging. While rehabilitative strategies such as swallowing therapy currently represent the main treatment option, emerging evidence suggests that non-invasive central and peripheral neuromodulation techniques may provide adjunctive beneficial effects. Further research is warranted to better define their efficacy, optimal protocols, and long-term outcomes. Full article

Background: While mechanical alignment total knee arthroplasty (TKA) has long been the conventional surgical technique in patients with advanced osteoarthritis, kinematic alignment TKA has emerged as a promising alternative, designed to restore the knee’s native pre-arthritic anatomy. Since superiority of either technique remains inconclusive, we aimed to compare immediate and short-term postoperative outcomes of kinematic versus mechanical alignment TKA. Methods: This prospective cohort study was conducted at a tertiary care centre between January 2020 and August 2022, enrolling kinematic and mechanical alignment TKA patients. Outcomes were assessed during hospitalization and at 14 days postoperatively. Data collected included patient-reported outcome measures (PROMs), functional performance evaluations, pain scores, discharge disposition and hospital length of stay. Both univariate and multivariate regression analyses were conducted, adjusting for potential confounders. Results: The study included 103 patients, with 77 who underwent kinematic alignment and 26 mechanical alignment TKA. Patients in the kinematic alignment group demonstrated statistically significant better postoperative outcomes compared to those in the mechanical alignment group. Kinematic alignment TKA patients demonstrated superior functional performance on the Timed Up and Go test immediately postoperatively and were more frequently discharged home rather than to a rehabilitation facility. Hospital stay length and short-term PROMs also favoured the Kinematic alignment TKA group, showing statistically significant higher scores in the Oxford Knee Score, short form-12 Mental Component Summary, and the Knee Injury and Osteoarthritis Outcome Score Symptoms subscale. Conclusions: Kinematic alignment TKA offers superior immediate and short-term outcomes compared to mechanical alignment TKA, with benefits in functional recovery, hospitalization duration, and discharge disposition. This evidence supports kinematic alignment TKA as a viable alternative, aiding in patient and surgeon decision-making. Full article

Background: Unhoused individuals face significant health disparities and encounter numerous barriers to accessing adequate healthcare, resulting in high rates of chronic disease, mental illness, and untreated conditions in Houston, TX. The purpose of this study was to identify prevalent health conditions within a sample of unhoused adults and to identify patterns in patient characteristics and clinical health outcomes. Methods: This study utilized clinical and demographic data from n = 191 patients who received care at a student-run clinic embedded within a homeless drop-in center in Houston, TX. Data included patient demographics, chief complaints, social determinants of health (SDOHs), past medical history, on-site diagnoses, and provider actions. Results: The most prevalent issues were housing insecurity (36.1%), cardiovascular conditions (38.7%), and substance use (17.8%). Nearly half of all patients (46.6%) declined treatment or left before receiving care. Significant associations were found between patient demographics and provider responses, including differences by gender and age in treatment type and diagnostic categorization. Conclusions: These findings underscore critical challenges in treatment adherence, diagnostic bias, and retention among unhoused populations. The study provides actionable recommendations for improving care coordination and continuity in low-barrier, student-run clinics serving medically underserved communities. Full article

Background: The rate of long-term outcomes, including arrhythmic episodes following implantable cardioverter–defibrillator (ICD) device replacements, is often unknown. Thus, the aim of this manuscript was to evaluate the risk of ICD or cardiac resynchronization therapy–defibrillator (CRT-D) therapies in remotely monitored patients following device replacement. Methods: Data from 134 patients who underwent ICD/CRT-D replacement or upgrade were analyzed. Kaplan–Meier estimates, as well as Cox proportional hazards regression, were used to present long-term outcomes and predictors of study endpoints, these being all-cause mortality, and appropriate and inappropriate ICD/CRT-D therapies. Results: Among the cohort, 51.5% of patients received ICDs and 48.5% received CRT-Ds; the median (quartile 1–quartile 3) LVEF at replacement was 23.0% (18.0–28.0%). In 11 (8.2%) patients, the LVEF at replacement was higher than 35%. During the median (Q1–Q3) follow-up of 3.0 (1.4–5.0) years, 32.1% experienced appropriate and 6.0% experienced inappropriate therapies. The all-cause mortality rate was 38.0%, and appropriate antitachycardia pacing (ATP), a reduced baseline LVEF, and no history of myocardial infarction were independent predictors of death (odds ratios of 1.87 for appropriate ATP, 0.88 per 1% of the LVEF and 0.54 for a history of MI, respectively). The rate of appropriate device therapies was numerically lower in patients whose LVEF improved (19.8% vs. 33.3% and 0% vs. 6.5%, for appropriate and inappropriate therapies). An LVEF of >35% at replacement did not influence the analyzed outcomes. Conclusions: In patients who underwent ICD/CRT-D replacement, an improvement in LVEF was not identified as either a predictor of improved survival or of a lower risk of needing device therapies. Further stratification models are needed to evaluate the arrhythmic risk in patients after generator replacements. Full article

Background: Metabolic syndrome (MS) and obstructive sleep apnea (OSA) frequently coexist, exacerbating systemic inflammation, oxidative stress, and metabolic dysregulation. This study evaluates the effects of dietary and probiotic interventions, compared to a non-intervention control group, on metabolic, hemodynamic, and neurochemical parameters, with a specific focus on the neurotransmitters GABA and glutamate. Methods: In a prospective randomized study (2020–2023), 120 patients with coexisting MS and OSA were assigned to three groups: control (n = 36), diet therapy (n = 42), and diet therapy combined with probiotics (n = 42). Interventions lasted six months and included personalized dietary plans and probiotic supplementation. Outcome measures included BMI, visceral fat, HOMA index, lipid profile, oxygen saturation, and urinary GABA and glutamate levels. Unsupervised K-means clustering and principal component analysis (PCA) were applied to identify phenotypic response patterns based on delta values. Results: Diet therapy led to significant reductions in BMI (−15.7%, p = 0.001), visceral fat (−17.3%, p = 0.001), triglycerides (−14.6%, p = 0.003), uric acid (−9.5%, p = 0.011), and C-reactive protein (CRP) (−21.4%, p = 0.007). The combined intervention group exhibited further improvements in visceral fat (−22.8%, p = 0.001), glutamate (−18.2%, p = 0.002), and GABA levels (+19.5%, p = 0.001). Oxygen saturation improved across all groups, with the greatest increase in the probiotics group (+2.3%). Clustering analysis revealed three distinct response phenotypes—strong, moderate, and non-responders—highlighting inter-individual variability in treatment efficacy. Conclusions: Personalized dietary interventions, especially when paired with probiotics, effectively improve metabolic, inflammatory, and neurochemical profiles in patients with MS and OSA. Integrating clustering algorithms enables phenotype-specific stratification, offering a step toward precision lifestyle medicine. Future studies should explore long-term outcomes and refine microbiota-targeted approaches to optimize intervention efficacy. Full article

Background/Objectives: Plasma cell gingivitis (PCG) is a rare, benign, non-dental-plaque-induced inflammatory condition characterized by dense subepithelial infiltration of polyclonal plasma cells. Due to its nonspecific clinical presentation, PCG represents a diagnostic challenge. This case report aims to describe a clinical case of PCG, highlighting the diagnostic process, histopathological correlation, and therapeutic approach. Methods: A 57-year-old male presented with a polypoid, erythematous, and edematous gingival lesion in the anterior maxillary region, with spontaneous bleeding on probing. Following clinic assessment, an incisional biopsy was performed, alongside complete hematological and inflammatory profiling. Histological and immunohistochemical analyses revealed the presence of an inflammatory infiltrate. Results: Histological evaluation revealed spongiotic squamous epithelium characterized by a dense plasma cell infiltrate with a liquenoid pattern of CD3-positive T and CD20-positive B lymphocytes. A polytypic expression of kappa and lambda light chains was also detected. The patient underwent topical corticosteroid therapy, showing progressive clinical improvement and resolution of symptoms, although minor mucosal involvement persisted. Conclusions: PCG remains a rare and underdiagnosed condition requiring integration of clinical, hematological, and histopathological data for accurate diagnosis. While corticosteroids remain the first-line therapy, emerging treatments, including photobiomodulation, may offer future adjunctive strategies to improve outcomes and reduce recurrence. Full article

Background: Delayed onset muscle soreness (DOMS) frequently occurs after engaging in strenuous physical activity. The manifestation of DOMS is often associated with changes in the biomechanical and viscoelastic characteristics of the affected muscles. Materials and Methods: Forty participants were enrolled and randomly assigned to two groups: the intervention group receiving transcutaneous electrical nerve stimulation (TENS, n = 20) and a control group (n = 20). A fatigue-inducing protocol targeting the gastrocnemius muscle was implemented to elicit DOMS. The effectiveness of TENS was assessed by evaluating alterations in the biomechanical and viscoelastic properties of the muscle. Pain intensity was recorded using the Numeric Rating Scale (NRS) at five time points: before the study began, three times during the intervention, and once at the conclusion of the study. Results: No statistically significant changes have been found regarding muscle tone (p = 0.162) and stiffness (p = 0.212) in Group 1. However, a statistically significant lower level of stiffness in Group 1 after the end of therapy has been detected (p = 0.008). Decrement values decreased statistically significantly, both in Group 1 (p = 0.015) and in Group 2 (p = 0.014). There were no statistically significant differences in decrement level between Group 1 and 2. Relaxation and creep decreased statistically insignificantly in both groups. At the end of the observation period (Day 4), statistically significant (p = 0.027) lower pain intensity was observed in Group 1. Conclusions: It has been demonstrated that TENS has had limited effectiveness in restoring baseline biomechanical and viscoelastic parameters of muscles that undergo changes during DOMS. TENS significantly relieves pain symptoms occurring in DOMS. Full article

Sickle cell disease (SCD) is a hereditary hemoglobin disorder characterized by chronic hemolysis and recurrent vaso-occlusive crises, leading to a wide spectrum of complications. While common SCD manifestations have well-established management protocols, rare and atypical complications pose significant diagnostic and therapeutic challenges. A critical barrier is diagnostic overshadowing, where common SCD symptoms (pain, fever, respiratory distress) mask infrequent but life-threatening conditions, resulting in delayed recognition and suboptimal outcomes. This narrative review synthesizes the literature from 2000–2025 on rare SCD complications, including atypical neurological events (e.g., spontaneous epidural or subdural hematoma, central retinal artery occlusion, cerebral arteriovenous malformations, posterior reversible encephalopathy syndrome), uncommon hematologic syndromes (acute leukemia, extramedullary hematopoiesis in unusual sites, hemophagocytic lymphohistiocytosis), severe cardiopulmonary emergencies (acute multiorgan failure and fat embolism syndromes), unusual hepatic crises (acute hepatic sequestration, intrahepatic cholestasis), and others (e.g., compartment syndrome). Key insights underscore the need for high clinical suspicion and prompt use of advanced diagnostics (e.g., MRI, specialized laboratory tests) when patients present with atypical or disproportionate symptoms. Clinical implications: Heightening clinician awareness of these rare complications and implementing structured diagnostic strategies can facilitate earlier intervention, improving outcomes and reducing the high morbidity and mortality associated with these infrequent but severe events.
