Dental restorations must replicate the natural appearance of teeth while ensuring biocompatibility and durability. This study evaluated the surface characteristics and color stability of three dental composites—Herculite Ultra XRV, G-ænial A’CHORD, and Omnichroma—exposed to acidic beverages (red wine, black coffee, and Coca-Cola). Sixty disk-shaped specimens were prepared, polished, and immersed in these beverages. Surface roughness was assessed using profilometry and SEM analysis, hydrophobicity via contact angle analysis, and surface charge through streaming potential measurements. Color stability was evaluated using a spectrophotometer, and the pH levels of the solutions were recorded. Results showed that Herculite Ultra XRV had the highest mean contact angle (79.46° ± 6.52), indicating superior hydrophobicity, while Omnichroma had the lowest (64.94° ± 3.08), indicating more hydrophilicity. Significant color changes were observed, especially in black coffee, with ∆E values indicating notable discoloration. The acidic pH of the solutions increased surface roughness and color changes. Statistical analyses confirmed significant increases in surface roughness and color change for all composites, with the nanohybrid resin composite showing the greatest variability. These findings highlight the need for dental restorative materials with enhanced resistance to acidic environments to improve the longevity and esthetics of dental treatments.

Secondary hyperparathyroidism (SHPT) in chronic kidney disease often necessitates parathyroidectomy (PTX), but this definitive treatment can precipitate hungry bone syndrome (HBS)—a profound, prolonged hypocalcemia caused by the rapid skeletal uptake of minerals after surgery. HBS results from the abrupt cessation of parathyroid hormone (PTH)-driven bone resorption while bone formation continues, leading to intensive mineral deposition (mainly calcium) into chronically demineralized bone. Clinically, HBS ranges from asymptomatic biochemical disturbances to life-threatening hypocalcemia with tetany, seizures, and/or cardiac arrhythmias. This illustrative review synthesizes current knowledge of HBS pathogenesis and management in the context of SHPT. We detail how the high-turnover bone remodeling state of SHPT (osteitis fibrosa cystica) creates an expansive unmineralized osteoid pool that avidly mineralizes post-PTX. We also explore molecular mechanisms (e.g., RANKL/OPG dysregulation, Wnt/β-catenin activation, osteocyte-driven signals, and calcium-sensing receptor effects) that underpin this process. Key preoperative risk factors for HBS include very elevated PTH and alkaline phosphatase levels, large skeletal calcium deficits, younger patient age, and total PTX. We outline the typical postoperative course of HBS, phased from immediate acute hypocalcemia to a nadir and gradual recovery. Prevention and management strategies are emphasized, centered on vigilant monitoring and aggressive calcium and calcitriol supplementation, with preoperative optimization (e.g., vitamin D loading, calcimimetics) to mitigate severity. By enhancing risk stratification and perioperative care, clinicians can improve outcomes and safely navigate patients through this challenging complication of endocrine surgery.

Common Juniper (Juniperus communis L.) is a gymnosperm that stands out through its fleshy, spherical female cones, often termed simply “berries”. The cone berries and various vegetative parts (leaves, twigs and even roots) are used in traditional phytotherapy, based on the beneficial effects exerted by a variety of secondary metabolites. While the volatile compounds of Juniperus communis are known for their aromatic properties and have been well-researched for their antimicrobial effects, this review shifts focus to non-volatile secondary metabolites—specifically diterpenes, lignans, and biflavonoids. These compounds are of significant biomedical interest due to their notable pharmacological activities, including antioxidant, anti-inflammatory, antimicrobial, and anticancer effects. The aim of this review is to offer an up-to-date account of chemical composition of Juniperus communis and related species, with a primary emphasis on the bioactivities of diterpenes, lignans, and biflavonoids. By examining recent preclinical and clinical data, this work assesses the therapeutic potential of these metabolites and their mechanisms of action, underscoring their value in developing new therapeutic options. Additionally, this review addresses the pharmacological efficacy and possible therapeutic applications of Juniperus communis in treating various human diseases, thus supporting its potential role in evidence-based phytotherapy.

Background/Objectives: Diet is a primary and modifiable determinant of gut microbiota composition, diversity, and metabolic activity, thereby shaping microbial-derived metabolites, immune and inflammatory signalling, neuroendocrine regulation, and neural communication with the central nervous system. Western dietary patterns, characterised by high intake of ultra-processed foods, saturated fats, and low dietary fibre, are consistently associated with gut dysbiosis, impaired intestinal barrier function, chronic low-grade inflammation, and increased risk of depression, anxiety, cognitive impairment, and neurodegenerative disorders. Methods: This narrative review synthesises evidence from human observational studies, randomised controlled trials, animal models, and mechanistic investigations examining interactions among diet, gut microbiota, and mental health or neurobiological outcomes. Literature searches were conducted in PubMed, Scopus, and Web of Science for articles published up to December 2025. Results: The study highlights the therapeutic potential and limitations of dietary interventions, prebiotics, probiotics, and psychobiotics, and critically evaluates them. Also facilitates an improved understanding of diet–microbiome–brain interactions, which may help the development of personalised, nutrition-based strategies integrated into mental health prevention and clinical care. Conclusions: These findings support diet-based, microbiome-informed strategies as scalable adjuncts in mental health prevention and care.

Background/Objectives: Secondary hyperparathyroidism (SHPT) is a prevalent complication in end-stage renal disease, often necessitating surgical intervention when refractory to medical therapy. The optimal surgical strategy—subtotal parathyroidectomy (SPTX) versus total parathyroidectomy with/without autotransplantation (TPTX ± AT)—remains debated, especially considering postoperative complications like persistent HPT and hungry bone syndrome (HBS). This study aimed to compare early surgical outcomes and identify predictors for postoperative complications in patients undergoing SPTX and TPTX + AT. Methods: We conducted a retrospective, single-center observational study involving 93 dialysis patients who underwent PTX for drug-refractory SHPT. Patients were analyzed according to surgical procedure (SPTX vs. TPTX + AT), focusing on postoperative complications such as cervical bleeding, reintervention rates, and the incidence of HBS. Multivariate logistic regression was utilized to identify predictors of these outcomes. Results: TPTX + AT demonstrated superior control of HPT, with significantly lower rates of reintervention compared to SPTX (7.1% vs. 23.5%, p = 0.037). However, TPTX + AT was associated with a higher incidence of HBS (57.1% vs. 35.3%, p = 0.039). Independent predictors of reintervention included absence of concomitant thymectomy, preoperative hypercalcemia, fewer visualized glands preoperatively, and preoperative PTH > 2000 pg/mL. Elevated alkaline phosphatase levels (>300 U/L), severe bone pain, and the TPTX procedure itself were significant predictors of HBS. Conclusions: Surgical strategy for SHPT should be individualized, balancing the lower recurrence risk associated with TPTX + AT against its higher likelihood of postoperative hypocalcemia. Preoperative biochemical markers and clinical features could potentially influence operative decision-making and optimize patient outcomes.

The cone berries of Juniperus communis L. are rich in bioactive compounds, but biological properties of extracts are strongly influenced by the solvents used to obtain them. Therefore, this study aimed to evaluate the effect of solvent fractionation on the targeted polyphenolic profile and associated antioxidant, antimicrobial, and anticancer activities of pseudo-fruit extracts. The crude ethanolic extract was subjected to liquid–liquid partitioning to obtain ethyl acetate and n-butanol-soluble fractions, which were characterized by HPLC–MS and FTIR, while total polyphenol content was determined using the Folin–Ciocâlteu method and biological activities were assessed through DPPH, antimicrobial assays, and in vitro cytotoxicity on A375 melanoma and HaCaT keratinocyte cell lines. The ethyl acetate-soluble fraction showed the highest polyphenol content (361.08 ± 17.72 mg chlorogenic acid equivalents/g extract) and was enriched in hyperoside, whereas the n-butanol-soluble fraction contained lower phenolic levels and higher rutoside content; both fractions exhibited antioxidant activity correlated with phenolic content and weak-to-moderate antimicrobial activity, particularly against Streptococcus pyogenes. Cytotoxicity assays revealed a dose-dependent antiproliferative effect, with the ethyl acetate fraction displaying higher activity and greater selectivity toward melanoma cells, confirmed by apoptosis-related morphological changes. These findings demonstrate that solvent polarity plays a critical role in enriching bioactive phytochemicals and support the potential of J. communis fractions as sources of antioxidant and selective anticancer compounds.
