Background/Objectives: Current menopause assessment instruments primarily evaluate vasomotor, somatic, and urogenital symptoms, with limited attention to oral, sensory, and integrated psychological domains. Evidence that oral tissues are estrogen-responsive suggests that oral symptoms may represent an important but underrecognized component of menopausal burden. This study aimed to develop and provide initial psychometric validation of the Multidimensional Menopausal Burden Questionnaire (MMBQ-44), a 44-item instrument integrating systemic, oral, and psychological symptoms. Methods: A cross-sectional validation study was conducted in 308 women aged 45–65 years (perimenopausal n = 66, menopausal n = 40, postmenopausal n = 202). The MMBQ-44 combined items from the Menopause Rating Scale (MRS), Xerostomia Inventory (XI), Oral Health Impact Profile-14 (OHIP-14), and psychological measures derived from the PHQ-9, GAD-7, and HADS. Instrument development included expert review, cognitive interviewing, and field testing. Psychometric evaluation assessed item performance, internal consistency, factor structure, discriminant validity, and known-groups validity. Exploratory factor analysis used principal axis factoring with promax rotation, with factor retention determined by parallel analysis. Results: Internal consistency was good to excellent across domains (Cronbach’s α: 0.813–0.941; McDonald’s ω: 0.864–0.953). All corrected item–total correlations exceeded 0.30. The questionnaire showed strong factorability (KMO = 0.931; Bartlett’s χ² = 9006.2, p < 0.001). Parallel analysis identified four factors explaining 48.6% of total variance. Psychological and OHIP domains emerged clearly, whereas several MRS and XI items cross-loaded onto related factors. Most HTMT ratios were below 0.85, supporting discriminant validity. Floor effects were observed for OHIP (37.0%) and XI (23.4%). Known-groups validity was modest, with OHIP scores differing significantly across menopausal stages. Conclusions: The MMBQ-44 demonstrates strong reliability and acceptable construct validity as an integrative screening instrument for menopausal burden. Further confirmatory studies and refinement of oral symptom items are warranted.

The purpose of this study was to examine the utilization of 0–45 μm aluminum hydrate fraction (gibbsite) manufactured by Alum SA Tulcea, as a precursor in the hydrothermal synthesis process of nanosize boehmite from gibbsite suspensions. Furthermore, the use of the produced material as adsorbent of lanthanum (III) ions was investigated using aqueous solutions. Thermogravimetric analysis (TG), Fourier Transform InfraRed Spectroscopy (FT-IR), Wide-Angle X-Ray Scattering (WAXS), and atomic force microscopy (AFM) were used to demonstrate the preparation of the required material. Additionally, the material point of zero charge (pHpzc) and material specific surface (using BET approach) were evaluated. By conducting adsorption studies, the specific parameters for the lanthanum adsorption process were evaluated. The effects of pH, the ratio of adsorbent material to La(III) quantity from aqueous solution, contact time, and La(III) initial concentration were also assessed. Based on the obtained experimental data, it was proved that the maximum adsorption capacity of 97.7 mg/g was obtained for a solid:liquid ratio = 0.1 g:25 mL, pH between 3 and 6, temperature of 298 K, and contact time of 90 min. The studied adsorption process is most effectively described by the Sips model, suggesting an intricate interaction among the adsorbent material and La (III) ions. The prepared adsorbent exhibited a good desorption capacity (higher than 93%) when 20% HCl was used for desorption.

Background: Non-Hodgkin lymphoma (NHL) involving the ear, nose, and throat (ENT) region encompasses several established lymphoma entities with heterogeneous anatomical presentations. This study describes the clinicopathological features of a selected institutional cohort. Methods: We conducted a single-center retrospective case series of adult patients with NHL documented in institutional records during 2019–2021. Extranodal ENT-organ involvement was distinguished from cervical nodal disease without documented ENT-organ infiltration. Clinical, pathological, staging, treatment, and available follow-up information were reviewed descriptively. Results: Nineteen distinct patients were included (twelve in 2019, three in 2020, four in 2021). The median recorded age was 64 years, and 10 patients (52.6%) were male. Fourteen patients (73.7%) had extranodal ENT-organ involvement, and five (26.3%) had cervical nodal involvement only. The palatine tonsil was the most frequent index site (42.1%). Follicular lymphoma and mantle cell lymphoma were each recorded in four patients (21.1%). All final pathological diagnoses were recorded as B-cell lymphoma entities, although individual immunophenotypic findings were incomplete. Conclusions: This single-center retrospective case series highlights the anatomical and histopathological heterogeneity of NHL involving ENT-region structures. Larger multicenter studies with standardized clinicopathological assessment and longitudinal follow-up are needed to further characterize these presentations and their clinical outcomes.

Background/Objectives: Medication-associated xerostomia is a clinically relevant adverse effect, but its contribution to oral symptom burden in midlife women remains insufficiently characterized. This study investigated the association between xerogenic medication exposure and xerostomia burden across the menopausal transition and whether this association extended to broader oral symptoms. Methods: This cross-sectional study included 306 Romanian women aged 45–65 years. Medication exposure was assessed in two complementary ways: a medication-list-derived definition, in which reported medicines were coded into therapeutic classes with recognized xerogenic potential (n = 54; 17.6%), regarded as the pharmacological reference measure, and participant-reported use of medication potentially associated with dry mouth (n = 39; 12.7%), which additionally reflects patient recognition of xerogenic exposure. Outcomes were a six-item xerostomia symptom score (XSS-6; 0–18) and a nine-item oral symptom score (OSS-9; 0–27), both derived from the MMBQ-44. Associations were evaluated using two-part models adjusted for age, menopausal stage, body mass index, smoking, medication burden, and psychological symptom burden, with complementary sensitivity analyses. Results: Xerostomia symptoms were more frequent among women reporting xerogenic medication (94.9% vs. 71.5%; unadjusted OR 7.36, 95% CI 1.73–31.30), and participant-reported exposure remained associated with greater XSS-6 severity after full adjustment (+1.28 points, 95% CI 0.22–2.34). With the medication-list-derived definition, unadjusted associations were present (rate ratio 1.50, 95% CI 1.08–2.10) but attenuated to near-null estimates after full adjustment (severity difference 0.06 points; rate ratio 1.17, 95% CI 0.79–1.71). Psychological symptom burden was independently associated with both outcomes, and no independent association with OSS-9 was observed for either exposure definition. Agreement between definitions was moderate (85.3%; Cohen kappa 0.43); only 24/54 (44.4%) women identified from medication lists recognized taking medication capable of causing dry mouth. Conclusions: Pharmacologically defined xerogenic exposure showed weak independent associations with xerostomia burden after full adjustment, whereas the stronger associations observed for participant-recognized exposure may partly reflect symptom-driven awareness and should be read as an upper bound. Limited recognition of xerogenic exposure points to a medication-safety communication gap. Prospective studies with verified medication exposure, dose and duration data, and objective salivary measurements are needed to clarify causality.

Background and Objectives: MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression and have emerged as potential biomarkers in type 2 diabetes mellitus and its complications. This pilot exploratory study aimed to identify circulating miRNAs with differential expression in plasma from patients with newly diagnosed type 2 diabetes mellitus compared to age- and sex-matched healthy controls. Materials and Methods: Peripheral venous blood samples were collected from diabetic patients (n = 24) and controls (n = 12). Due to the exploratory nature of the study and limited sample material, samples were pooled within each group prior to plasma separation. Total RNA, including miRNAs, was extracted from plasma and analyzed using a high-throughput qPCR panel. Two normalization methods were applied to assess miRNA expression, and overlapping results were used for downstream analysis. Fold regulation was calculated using the 2^(−ΔCt) method. Results: A total of 33 and 42 miRNAs were identified as differentially expressed using the first and second normalization methods, respectively. Fourteen miRNAs were consistently downregulated across both methods. Several of these miRNAs, including hsa-miR-26a-5p, hsa-miR-146a-5p, hsa-miR-186-5p, hsa-miR-19a-3p, and hsa-miR-652-3p, have been previously associated with glucose metabolism, inflammation, and diabetic complications, such as retinopathy, neuropathy, and endothelial dysfunction. The pooling strategy enabled an efficient exploratory assessment of miRNA expression patterns while reducing inter-individual variability. Conclusions: This exploratory pilot study identifies a panel of circulating miRNAs with altered expression in pooled plasma samples from patients with newly diagnosed type 2 diabetes mellitus. These findings provide preliminary insights that warrant further validation in larger, individual-level studies to assess their diagnostic and prognostic potential.

Background and Objectives: Drug repurposing provides an opportunity to identify anticancer activities among established pharmacological agents. Labetalol (LB), an α₁- and non-selective β-adrenergic receptor antagonist, has been insufficiently investigated in melanoma. This study evaluated the potential anti-melanoma activity of LB in A375 human melanoma cells, compared its effects with those observed in HaCaT immortalized non-tumoral keratinocytes, and investigated the cellular mechanisms associated with LB-induced cytotoxicity. Materials and Methods: A375 and HaCaT cells were exposed to 75–500 μM LB for 24 h. Cell viability and lysosomal dye retention were assessed using MTT and NRU assays. A DMSO-only concentration series (0.075–0.50% v/v) was additionally evaluated by MTT in both cell lines. Mitochondrial membrane potential, mitochondrial staining patterns, nuclear morphology, cytoskeletal organization, caspase-3/7 and caspase-9 activities, and plasma membrane integrity were evaluated using JC-1, MitoTracker Red CMXRos, immunofluorescence, luminescence-based caspase assays, and AO/PI staining. The acute irritation potential of 500 μM LB was assessed using the HET-CAM assay. Results: DMSO alone did not significantly reduce viability over the investigated concentration range in either cell line. LB reduced A375 cell viability in a concentration-dependent manner, with a 24 h IC₅₀ of 422.5 μM and a viability of 33.61% at 500 μM. Under the same experimental conditions, HaCaT viability remained at 89.01% at 500 μM, and an IC₅₀ was not reached within the investigated concentration range. At the highest concentration, neutral red uptake and the JC-1 aggregate/monomer ratio decreased to approximately 33% and 24% of the corresponding control values, respectively. The apoptotic index increased from approximately 3% in control cells to 31%, while caspase-3/7 and caspase-9 activities increased to approximately 482% and 324% of the control. Qualitative imaging demonstrated mitochondrial staining redistribution, cytoskeletal disorganization, apoptosis-associated morphology, and loss of plasma membrane integrity at higher concentrations. In the HET-CAM assay, 500 μM LB produced a mean irritation score of 0.71 ± 0.27, within the non-irritant range. Conclusions: LB displayed concentration-dependent in vitro cytotoxicity in A375 melanoma cells, whereas HaCaT keratinocytes showed limited changes under the investigated conditions. LB treatment was also associated with mitochondria-associated apoptotic signaling in A375 cells. These findings provide preliminary evidence supporting further investigation of LB within a melanoma-directed drug-repurposing strategy. Additional studies are required to establish receptor dependence, achievable local exposure, safety, and translational relevance.
