Asthma represents a heterogeneous disorder characterized by a dynamic balance between pro-inflammatory and anti-inflammatory forces, with allergic sensitization contributing substantially to airway hyperresponsiveness and remodeling. Central to its pathogenesis are cytokines such as IL-4, IL-5, IL-13, IL-17, and IL-33, which drive recruitment of eosinophils, neutrophils, and other effector cells, thereby precipitating episodic exacerbations in response to viral and environmental triggers. Conventional biomarkers, including blood and sputum eosinophil counts, IgE levels, and fractional exhaled nitric oxide, facilitate phenotypic classification and guide the emerging biologic era. Monoclonal antibodies targeting IgE (omalizumab) and IL-5 (mepolizumab, benralizumab, reslizumab, depemokimab) have demonstrated the ability to reduce exacerbation frequency and improve lung function, with newer agents such as depemokimab offering extended dosing intervals. Itepekimab, an anti-IL-33 antibody, effectively engages its target and mitigates tissue eosinophilia, while CM310-stapokibart, tralokinumab, and lebrikizumab inhibit IL-4/IL-13 signaling with variable efficacy depending on patient biomarkers. Comparative analyses of these biologics, encompassing affinity, dosing regimens, and trial outcomes, underscore the imperative of personalized therapy to optimize disease control in severe asthma.

Postural disorders in children and adolescents have an increasing incidence. The aim of this study was to identify the type of postural defects in school-age and preschool children, as well as the external risk factors determined by an inadequate lifestyle. The research included 134 children aged between 5 and 18 years, in whom postural defects were identified. The project involved an examination of the children’s body posture, a survey of the parents to determine the children’s lifestyle, blood tests, and spinal X-rays. A significant percentage (76%) of the children included in the study were underweight. The examination of postural defects in the students revealed scoliosis in 21% of the patients, kyphosis in 7.5%, and lordosis in 1.5%, while 70% of the patients presented an association between at least two postural defects. As far as risk factors are concerned, we identified the presence of rickets sequelae in 70% of the patients, the presence of pectus excavatum in 43% of the patients, genu varum in 15%, and flat foot in 12%. Additionally, 90% of the children had an incorrect posture at the desk, while 42% incorrectly carried their backpack on one shoulder only. In terms of diet quality, associations between an inadequate diet and postural disorders were found for kyphosis, scoliosis, and other deformities. In conclusion, postural abnormalities in children have an increased incidence from an early age and are a result of the change in lifestyle in recent years, represented by sedentarism, a lack of physical activity, the excessive use of electronic devices, stress, and an inadequate diet.

Antibodies against the NR1 or NR2 subunits of the NMDA receptor are linked to anti-N-methyl-D-aspartate (NMDA) receptor encephalitis, a type of encephalitis that mainly affects women. Clinicians who treat patients of all ages should be aware of this type of encephalitis since it may be a treatable differential for symptoms and indicators observed in neurology and psychiatric clinics. Auditory and visual hallucinations, delusions, altered behavior (often accompanied by agitation), reduced consciousness, motor disruption (from dyskinesia to catatonia), seizures, and autonomic dysfunction are typical clinical characteristics. In recent years, the incidence of autoimmune encephalitis diagnoses has markedly risen among adults, children, and adolescents. This fact is unequivocally connected to the dynamic evolution of novel diagnostic techniques and the advancement of medical knowledge. A specific variant of this illness is anti-NMDA receptor encephalitis. Psychiatrists frequently serve as the initial specialists to treat patients with this diagnosis, owing to the manifestation of psychiatric symptoms associated with the condition. The differential diagnosis is quite challenging and predominantly relies on the patient’s history and the manifestation of characteristic clinical signs. Given its high prevalence, anti-NMDA receptor encephalitis should be included in the differential diagnosis in routine psychiatric treatment. We provide an overview of the research on the condition, covering its prognosis, management, epidemiology, differential diagnosis, and clinical presentation.

Cyclodextrin (CD)-based drug delivery systems have emerged as a promising strategy to overcome limitations commonly encountered in antidepressant therapy, including low bioavailability, poor solubility, and suboptimal penetration of the blood–brain barrier. This review synthesizes current evidence demonstrating that complexing various classes of antidepressants—such as tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), and atypical antidepressants—with β-CD or its derivatives significantly enhances drug solubility and stability. In addition, encapsulation with CDs can diminish systemic toxicity and improve pharmacokinetics, thereby helping to optimize dosage regimens and reduce adverse effects. Analysis of published in vitro and in vivo studies indicates that CD formulations not only boost therapeutic efficacy but also enable sustained or targeted release, which is critical for drugs requiring precise plasma and tissue concentrations. When compared to other carriers (e.g., liposomes, polymeric nanoparticles, dendrimers), CD-based systems often stand out for their ease of formulation, biocompatibility, and cost-effectiveness, although limited drug-loading capacity can be a drawback. We recommend expanding in vivo trials to substantiate the clinical benefits of CD–antidepressant complexes, particularly for treatment-resistant cases or specific subpopulations (e.g., elderly and pediatric patients). Additional investigations should also explore hybrid systems—combining CDs with advanced nano- or macroparticles—to amplify their advantages and address any limitations. Ultimately, integrating CDs into antidepressant regimens holds substantial potential to refine therapy outcomes, reduce adverse events, and pave the way for more personalized, effective interventions for depression.

This article investigates the link between Helicobacter pylori (H. pylori) infection and cardiovascular and neurological disorders. Recent research suggests that H. pylori may play a role in cardiovascular diseases like atherosclerosis, myocardial infarction, and stroke, as well as neurological diseases including Alzheimer’s disease, multiple sclerosis, and Parkinson’s disease. Cardiovascular Diseases: H. pylori induces endothelial dysfunction and chronic inflammation, promoting atherosclerotic plaque formation and other cardiac complications. High infection prevalence in cardiovascular patients implies that systemic inflammation from H. pylori accelerates disease progression. Eradication therapies combined with anti-inflammatory and lipid-lowering treatments may reduce cardiovascular risk. Neurological Diseases: H. pylori may contribute to Alzheimer’s, multiple sclerosis, and Parkinson’s through systemic inflammation, neuroinflammation, and autoimmune responses. Increased infection prevalence in these patients suggests bacterial involvement in disease pathogenesis. The eradication of H. pylori could reduce neuroinflammation and improve outcomes. Discussions and Future Research: Managing H. pylori infection in clinical practice could impact public health and treatment approaches. Further research is needed to clarify these relationships. Longitudinal and mechanistic studies are essential to fully understand H. pylori’s role in these conditions. Conclusions: H. pylori infection is a potential risk factor for various cardiovascular and neurological conditions. Additional research is critical for developing effective prevention and treatment strategies. Targeted therapies, including H. pylori eradication combined with anti-inflammatory treatments, could improve clinical outcomes. These findings highlight the need for an integrated clinical approach to include H. pylori evaluation and treatment.

Diabetes mellitus is a chronic metabolic disease that has a significant impact on public health and is becoming more and more common worldwide. Although effective, conventional therapies are often limited by high cost, adverse effects, and issues with patient compliance. As a result, there is growing interest in complementary and alternative therapies. Medicinal plants have played an essential role in diabetes treatment, especially in regions such as Romania, where biodiversity is high and traditional knowledge is well preserved. The pathophysiology, risk factors, and worldwide burden of diabetes are examined in this review, with an emphasis on the traditional use of medicinal plants for glycemic control. A total of 47 plant species were identified based on ethnopharmacological records and recent biomedical research, including both native flora and widely cultivated species. The bioactive compounds identified, such as flavonoids, triterpenic saponins, polyphenols, and alkaloids, have hypoglycemic effects through diverse mechanisms, including β-cell regeneration, insulin-mimetic action, inhibition of α-glucosidase and α-amylase, and oxidative stress reduction. A systematic literature search was conducted, including in vitro, in vivo, and clinical studies relevant to antidiabetic activity. Among the species reviewed, Urtica dioica, Silybum marianum, and Momordica charantia exhibited the most promising antidiabetic activity based on both preclinical and clinical evidence. Despite promising preclinical results, clinical evidence remains limited, and variability in phytochemical content poses challenges to reproducibility. This review highlights the potential of Romanian medicinal flora as a source of adjunctive therapies in diabetes care and underscores the need for standardization and clinical validation.
