Background: This study aimed to assess the illness perceptions of patients diagnosed with hypertension from a primary care perspective. It also sought to identify the sociodemographic and clinical factors associated with illness perception. Methods: A cross-sectional descriptive study was conducted between February and March 2025, involving 116 hypertensive patients who attended family medicine outpatient clinics at Rize Training and Research Hospital, Turkey. Data were collected using a sociodemographic questionnaire and the Brief Illness Perception Questionnaire (BIPQ). Nonparametric tests, including the Mann–Whitney U test, Kruskal–Wallis H test with Dunn’s post hoc analysis, and Spearman’s correlation analysis, were employed to evaluate the data. Results: The mean age of the participants was 69.01 ± 6.07 years, with 76.7% of the participants aged over 65 years. The median total BIPQ score was 47.0, indicating a moderate illness perception. A significant negative correlation was observed between age and the total BIPQ score (Rho = −0.443, p < 0.001). Higher illness perception levels were significantly associated with lower educational attainment, shorter duration of antihypertensive treatment, and attribution of hypertension to stress, genetic predisposition, diet, and occupational factors (p < 0.05). Conclusions: Illness perceptions among patients with hypertension are shaped by various sociodemographic and clinical determinants. Enhancing awareness of these perceptions in primary care may support improved treatment adherence and better health outcomes. Interventions that strengthen health literacy and offer psychosocial support may contribute to more effective hypertension management. Full article

Colostrum is a nutrient-rich fluid secreted by mammals shortly after birth, primarily to provide passive immunity and support early immune development in newborns. Among its various sources, bovine colostrum is the most widely used supplement due to its high bioavailability, safety profile, and clinically supported health benefits. Rich in immunoglobulins, lactoferrin, growth factors, and antimicrobial peptides, bovine colostrum exhibits diverse biological activities that extend beyond neonatal health. Recently, the rising prevalence of cancer—driven by environmental stressors such as radiation, processed foods, and chronic inflammation, as well as non-environmental hereditary factors including germline mutations, family history, and epigenetic inheritance—has fueled interest in natural adjunctive therapies. Scientific studies have explored the anticancer potential of bovine colostrum, highlighting its ability to modulate immune responses, inhibit tumor growth, induce apoptosis in cancer cells, and reduce inflammation. Key components including lactoferrin and proline-rich peptides have been identified as contributors to these effects. Additionally, bovine colostrum may help reduce the side effects of standard cancer treatments, such as mouth sores from chemotherapy or weakened immune systems, by helping to heal tissues and boost the body’s defenses. While large-scale clinical studies are still needed, current findings suggest that bovine colostrum holds promise as a supportive element in integrative cancer care. In conclusion, bovine colostrum represents a safe, bioactive-rich natural supplement with multifaceted therapeutic potential, particularly in oncology, owing to its key components such as lactoferrin, immunoglobulins, growth factors (e.g., IGF-1, TGF-β), and proline-rich polypeptides (PRPs), which contribute to its immunomodulatory, anti-inflammatory, and potential anticancer effects. Ongoing and future research will be crucial to fully understand its mechanisms of action and establish its role in evidence-based cancer prevention and treatment strategies. Full article

Background: Postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery with cardiopulmonary bypass (CPB) affecting between 5% and 40% of patients, which leads to hemodynamic instability, an increased risk of thromboembolism, decompensated heart failure, prolonged hospitalization, and higher treatment costs. Currently, there are no universally accepted guidelines for preventing POAF. Methods: A single-center, prospective, randomized controlled trial, “The Effect of Colchicine on the Occurrence of Atrial Fibrillation after Cardiac Surgery” (CAFE), ClinicalTrials.gov ID: NCT06798714, was conducted. The study included 140 patients with coronary artery disease randomized into two groups of 70 patients each. Group 1 (control group) received standard postoperative care. Group 2 (intervention group) received colchicine (Colchicum-Dispert at a dose of 500 mcg 4 h before coronary artery bypass grafting (CABG) with CPB and at a dose of 500 mcg twice daily for 10 days postoperatively) and underwent intraoperative pericardial fenestration using an original technique. Results: Perioperative colchicine administration combined with intraoperative pericardial fenestration reduced POAF incidence to 2.9% compared to the control group with POAF incidence of 12.9% (p < 0.05). This management strategy was not associated with an increased incidence of infectious complications, gastrointestinal disorders, or elevated levels of alanine aminotransferase, aspartate aminotransferase, or creatinine. Conclusions: Perioperative colchicine administration combined with pericardial fenestration during CABG with CPB is associated with a reduced POAF incidence, good tolerability, and does not contribute to an increased incidence of infectious complications or impaired liver and renal function.

There is growing evidence regarding non-pharmacological therapies such as music as a supportive approach for the treatment of various clinical conditions in humans. Physiological and neurobiological research suggests that music exposure is related to endorphin, endocannabinoid and dopamine release, favourable effects on autonomic nervous system functioning and is associated with decreased pain perception and reduced stress response. Further evidence in humans demonstrates a beneficial role of music application during the perioperative period by improving various outcome measures, such as the perioperative stress and anxiety levels, the sedation or general anaesthetic requirements, the pain levels, the analgesic requirements and other parameters related to patient prognosis, without reported side effects. Accordingly, such interventions have been considered as a method of environmental enrichment for animal welfare enhancement, by masking potentially disturbing background noises and by ameliorating anxiety or aggressive behaviours in different stressful settings in dogs and cats. Furthermore, research has been lately extended to the potential music’s effect in these species during the perioperative period, considered a stressful setting, as well. This review presents the existing evidence of music application focusing on the perioperative period of dogs and cats, as part of a multimodal approach, to improve their surgical outcome and welfare.

Introduction: The emergence of SARS-CoV-2 Omicron subvariants characterized by increased transmissibility and immune escape has raised concerns about the efficacy of current treatments. This systematic review and meta-analysis evaluated pharmacological and non-pharmacological interventions in Omicron-infected non-hospitalized patients, focusing on key clinical outcomes such as hospitalization, respiratory failure, ICU admission, and 30-day mortality. Methods: Searches were performed in MEDLINE, EMBASE, Web of Science, Cochrane, and ClinicalTrials.gov (last update: 13 July 2025). Eligible studies reported outcomes on antiviral agents, monoclonal antibodies, adjunctive therapies, or telemedicine. Random-effects meta-analyses were conducted when appropriate, with heterogeneity assessed by I². Publication bias was evaluated via funnel plots and Egger’s test. Subgroup analyses explored sources of heterogeneity. Results: Eighty-eight studies were included. Meta-analyses, comparing treatment vs. no treatment, revealed that nirmatrelvir/ritonavir reduced hospitalization by 52% (RR 0.48, 95% CI 0.36–0.63) and all-cause mortality by 84% (RR 0.16, 95% CI 0.11–0.24). Remdesivir reduced hospitalization by 70% (RR 0.30, 95% CI 0.19–0.47) and respiratory failure by 89% (RR 0.11, 95% CI 0.03–0.44). Sotrovimab decreased hospitalization (RR 0.71, 95% CI 0.54–0.93) and mortality (RR 0.34, 95% CI 0.19–0.61). Molnupiravir modestly reduced hospitalization (RR 0.80, 95% CI 0.70–0.91) and respiratory failure (RR 0.45, 95% CI 0.27–0.77). Conclusions: Nirmatrelvir/ritonavir and remdesivir remain important for reducing severe outcomes, while sotrovimab retains partial efficacy. Rapid access to antivirals remains an important factor in mitigating SARS-CoV-2’s burden. Full article

Hepatocellular carcinoma (HC) ranks as the fifth most prevalent form of cancer among humans and is a significant contributor to cancer-related deaths. During the latest year, an interesting scientific fascination arose around gold nanoparticles (AUNPs) following the recovery of their remarkable properties. Some studies suggest that AUNPs can enhance drug targeting in cancer treatment and reduce its toxicity. The major purpose of this paper is to systematically review the effectiveness, safety, and prospective mechanism of gold nanoparticles in delivering drugs for liver cancer treatment. Comprehensive research was conducted using major scientific databases (i.e., PubMed, Web of Science, and Scopus) to identify studies focusing on AUNPs in drug delivery systems. We mainly focused on studies that specifically analyzed liver cancer. The current results of the systematic review show that the application of gold nanoparticles (AUNPs) in liver cancer drug delivery enhances drug targeting to liver tumors. This efficient factor improves the bioavailability and elevates the therapeutic index of chemotherapeutic agents in treatment. This systematic review highlights the significant potential of AUNPs to increase the delivery of drugs for liver cancer treatment effectively. The major findings indicate that AUNPs improve the targeting and bioavailability of chemotherapeutic agents, enhancing therapeutic outcomes such as tumor suppression and improved survival rates. While the results of this review are encouraging; however, further research is necessary to ensure the safety and efficacy of AUNPs in clinical settings. Human trials must address concerns regarding long-term toxicity and regulatory approval. Full article

The rise in antimicrobial resistance and strict milk withdrawal regulations drive the search for safe, non-antibiotic intramammary therapies. This pilot field study focused on clinical parameters, including the somatic cell count (SCC) and the assessment of changes, as well as overall safety, which together enabled a prospective evaluation of whether the substance exerted any therapeutic effect. In this study, 48 Holstein–Friesian cows with naturally occurring clinical mastitis (somatic cell count > 400,000 cells/mL; single quarter) were randomized to receive either seven daily infusions of 10% pectin (n = 24) or two standard intramammary doses of a licensed multi-component antibiotic formulation (n = 24). The clinical severity scores (0–3) and SCC were monitored from 72 h before to 168 h after treatment initiation; the bacteriological cultures, milk TNF-α, milk yield, and blood hematology/biochemistry were also assessed. Both groups exhibited comparable and significant reductions in the mastitis scores and log₂-transformed SCC by 48 h post-treatment, with equivalent bacteriological cure rates and pathogen profiles (predominantly Streptococcus uberis, coagulase-negative staphylococci, and E. coli) and no local irritation, systemic adverse effects, or alterations in the milk yield, TNF-α, or blood parameters. These findings indicate that intramammary pectin at a 10% concentration is safe and well tolerated and that it provides efficacy equivalent to standard antibiotic therapy, supporting its potential as an alternative mastitis treatment that avoids antibiotic residues and contributes to antimicrobial stewardship.

Ultrasound-guided percutaneous interventions are well-established as effective treatments for shoulder calcific tendinopathy. In this work, we modified the conventional double-needle approach by incorporating a closed-circuit irrigation system and assessed the procedure’s clinical and radiological outcomes. We enrolled prospectively 24 patients (10 males; median age 54 years, IQR: 50–62) with painful calcific tendonitis of the shoulder between October 2023 and March 2024. All patients had a calcification > 5 mm treated with ultrasound-guided closed-circuit irrigation. Radiography, ultrasound evaluation, and OSS and SPADI clinical questionnaires were administered before the treatment and 3 months after. After the procedure, there was a significant reduction in the size of the calcifications (12 mm, IQR: 10–20 mm vs. 5.5 mm, IQR: 2–10 mm; p < 0.001). After the procedure, none of the patients experienced infections, while two developed bursitis. Three months after the procedure there were significant improvement in the OSS (16.5, IQR: 10–23 vs. 32, IQR: 36–45.5; p < 0.0001) and reduction in SPADI scores: pain (88, IQR: 74–95 before vs. 13, IQR: 4–24; p < 0.0001), disability (72, IQR: 60–90 before vs. 8, IQR: 4–20; p < 0.0001), and total score (78, IQR: 66–91 before vs. 11, IQR: 4–20; p < 0.0001). The closed-circuit double-needle irrigation for calcific tendinopathy of the shoulder is an effective treatment that improves both shoulder pain and function with a very low risk of short-term complications.

Background/Objectives: Emotional eating may be a consequence of acquired cue reactivity, a lack of control, or an inaccurate link between episodic overeating and negative affect, according to a new analysis of its standard measurement. This study was a controlled trial, which was designed to investigate the effect of personalized nutritional psychoeducation on emotional eating behavior. Methods: This study enrolled 95 participants (62 control group and 33 intervention group) who were randomized to treatment and assessed at 3-month follow-up. Over a period of 3 months, six thematic individual sessions were conducted with a frequency of every 15 days for the participants in the intervention group. The Three-Factor Eating Questionnaire (TFEQ) was used to assess feeding patterns and the manifestation of emotional food consumption in response to emotion. Results: At baseline, it appears that gender is positively related to TFEQ Emotional Score (β: 1.77 (random error: 0.57, p-value: 0.003). BMI (β: −0.11 (random error: 0.04, p-value: 0.003) and waist circumference are negatively related to the TFEQ Emotional Score. Conclusions: Although this study confirmed significant associations of emotional eating and gender, BMI, and waist circumference, the nutritional psychoeducation-based intervention did not exert the expected effects on emotional eating. More high-quality clinical trials need to further be designed to improve emotional eating behavior by applying relevant nutritional psychoeducation-based interventions. Full article

This review explores the therapeutic promise of natural compounds in modulating 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR), a key enzyme in cholesterol synthesis. HMGCR dysregulation is implicated in dyslipidemia, cardiovascular disease, and cancer, conditions linked to oxidative stress. While statins inhibit HMGCR, their side effects necessitate exploring alternatives. The review highlights various natural compounds—flavonoids, phenolic acids, stilbenes, and herbal formulations—with HMGCR-modulating and antioxidant capabilities. In vitro and in vivo studies suggest these compounds offer a promising avenue for treating HMGCR-related conditions. Synergistic effects are observed when combining natural products with statins, hinting at combination therapies that could lower statin dosages and reduce adverse effects. Natural HMGCR modulators hold therapeutic promise but face hurdles like limited in vivo data, regulatory issues, variability in composition, potential drug interactions, and safety concerns. Future research must prioritize comprehensive mechanistic studies, standardized preparations, and well-designed clinical trials. Overcoming these challenges through rigorous science is essential for integrating natural HMGCR modulators into clinical practice and improving patient outcomes in a safe and effective manner. Specifically, clinical trials should consider combination therapies and comparison with standard treatments like statins. More research is also needed on optimal dosages and treatment regimens.

Background/Objectives: Dyslipidemia is a prevalent metabolic disorder closely linked to cardiovascular complications and muscular pathologies, often managed using statins such as simvastatin. However, statin-induced myopathy remains a significant treatment-limiting side effect, necessitating the exploration of safe, natural alternatives. Spirulina platensis, a phytochemical-rich marine-derived cyanobacterium, has emerged as a promising bioactive nutraceutical with potent antioxidant and anti-inflammatory properties. This study evaluated the comparative effects of Spirulina platensis and simvastatin in attenuating dyslipidemia-induced skeletal muscle injury in adult male albino rats. Methods: Forty animals were allocated to the control and high-fat diet (HFD) groups. After 4 weeks, the dyslipidemic rats were subdivided into untreated, simvastatin-treated, and Spirulina platensis-treated subgroups. Serum lipid profile, creatine kinase (CK), and malondialdehyde (MDA) levels were assessed. Histological, ultrastructural, and immunohistochemical analyses were conducted to assess muscle fiber integrity and expression of TGF-β1 and Bcl2. Results: Spirulina platensis significantly improved lipid parameters, reduced CK and MDA levels, preserved muscle histoarchitecture, and downregulated fibrotic (↓TGF-β1) and apoptotic (↑Bcl2) responses compared to the dyslipidemic and simvastatin-treated groups. Our results proved that Spirulina platensis ameliorates the effects of statin-associated myopathy while exerting lipid-lowering, cytoprotective, and antifibrotic effects. Conclusion: These molecular and ultrastructural benefits position Spirulina platensis as a promising, natural alternative to statins for managing dyslipidemia and preventing statin-induced myopathy. Future translational and clinical studies are warranted to further validate its efficacy and safety, supporting its broader application in metabolic and muscle-related disorders. Full article

Cyclophilins (Cyps), a family of peptidyl-prolyl isomerases, play essential roles in the life cycle of coronaviruses by interacting with viral proteins and modulating host immune responses. In this systematic review, we examined cell culture, animal model, and clinical studies assessing the anti-viral efficacy of cyclosporine A (CsA, PubChem CID: 5284373) and its non-immunosuppressive derivatives against coronaviruses. CsA demonstrated robust anti-viral activity in vitro across a broad range of coronaviruses, including but not limited to HCoV-229E, SARS-CoV, MERS-CoV, and SARS-CoV-2, with potent EC₅₀ values in the low micromolar range. Non-immunosuppressive analogs such as Alisporivir and NIM811 exhibited similar inhibitory effects. In vivo, CsA treatment significantly reduced viral load, ameliorated lung pathology, and improved survival in coronavirus-infected animals. Clinical studies further indicated that CsA administration was associated with improved outcomes in COVID-19 patients, including reduced mortality and shorter hospital stays. Mechanistic studies revealed that CsA disrupts the formation of viral replication complexes, interferes with critical Cyp–viral protein interactions, and modulates innate immune signaling. These findings collectively demonstrate the therapeutic potential of cyclophilin inhibitors as broad-spectrum anti-virals against current and emerging coronaviruses. Full article

Liver cirrhosis, a progressive and often irreversible condition, exerts widespread systemic effects, with the skin frequently serving as a visible window into the extent of hepatic dysfunction. Cutaneous manifestations, such as spider angiomas, palmar erythema, jaundice, and pruritus, not only reflect underlying pathophysiologic changes but also serve as important, non-invasive diagnostic and prognostic markers of disease severity. Early detection of such cutaneous findings may allow for early treatment, optimize patient management, and improve outcomes. This review addresses the various cutaneous manifestations of liver cirrhosis, their pathogenesis, and their prognostic and diagnostic importance, emphasizing the need for heightened clinical awareness of the improvement in patient care.

Background/objectives: Optic nerve bending and chiasmal compression impair vision in patients with sellar lesions; however, their effect on optic nerve head (ONH) blood flow remains unclear. This study used laser speckle flowgraphy to examine the relationship between clinical features and ONH blood flow in patients with optic nerve bending and chiasmal compression. Methods: This retrospective study included 32 eyes (16 eyes with and 16 without optic nerve bending on the contralateral side) from 16 patients with sellar lesions. The best-corrected visual acuity (BCVA), simple visual field impairment score (SVFIS), optic nerve head mean blur rate (ONH-MBR), and six-segmented macular ganglion cell layer + inner plexiform layer (GCL + IPL) thickness were examined. Results: Preoperative BCVA and SVFIS in eyes with optic nerve bending were significantly worse than those in eyes without bending, and significantly correlated with the optic nerve-canal bending angle (ONCBA). After tumor resection, BCVA and SVFIS significantly improved in both groups. Preoperative ONH-MBR was significantly lower in bending eyes but increased significantly post-treatment in both groups. Preoperative ONH-MBR correlated with ONCBA, while postoperative ONH-MBR correlated with nasal GCL + IPL thickness. Conclusions: Optic nerve bending and chiasmal compression showed reduced blood flow to the ONH. These changes in blood flow may be associated with GCL + IPL thickness and optic nerve bending angle.

There is currently no effective therapeutic capable of arresting or inducing regression of primary or metastatic brain cancers. This article presents both pre-clinical and clinical studies supportive that a new bioengineered technology could induce regression and/or elimination of primary and metastatic brain cancers through three disease-modifying mechanisms. Transcranial Radiofrequency Wave Treatment (TRFT) is non-thermal, non-invasive and self-administered in-home to safely provide radiofrequency waves to the entire human brain. Since TRFT has already been shown to stop and reverse the cognitive decline of Alzheimer’s Disease in small studies, evidence is provided that three key mechanisms of TRFT action, alone or in synergy, could effectively treat brain cancers: (1) enhancement of brain meningeal lymph flow to increase immune trafficking between the brain cancer and cervical lymph nodes, resulting in a robust immune attack on the brain cancer; (2) rebalancing of the immune system’s cytokines within the brain or brain cancer environment to decrease inflammation therein and thus make for an inhospitable environment for brain cancer growth; (3) direct anti-proliferation/antigrowth affects within the brain tumor microenvironment. Importantly, these mechanisms of TRFT action could be effective against both visualized brain tumors and those that are yet too small to be identified through brain imaging. The existing animal and human clinical evidence presented in this perspective article justifies TRFT to be clinically tested immediately against both primary and metastatic brain cancers as monotherapy or possibly in combination with immune checkpoint inhibitors.
