There is significant inter-individual variability in the prevalence and severity of cisplatin-induced ototoxicity, which is greatly influenced by genetic and non-genetic factors that predispose the patient to the development of hearing loss. Currently, the focus should be on identifying patients who are more likely to develop ototoxicity based on genetic and non-genetic factors, as therapies to combat ototoxicity are limited or still under study. The severity of hearing loss and the time of its onset may be influenced by certain genetic polymorphisms or the dose administered, age, sex, diet, the administration of other drugs with ototoxic potential, and association with radiotherapy of the head and neck. Knowing the risk factors allows the doctor to manage each case in a personalized manner, preventing hearing damage, especially in the long term. With the help of PubMed and Scopus, we searched for relevant studies documenting the genetic and non-genetic risk in patients treated with cisplatin. This review article is a synthesis of the literature that points out the importance of these factors, encouraging genetic screening and improving quality of life in patients treated with cisplatin.

Inflammatory mediators play an important role in the pathogenesis of otitis media by initiating and maintaining an inflammatory response to infection. The presence of inflammatory mediators may be one of the reasons, in some patients, for acute otitis media transforming into chronic otitis media. The present study included 60 patients admitted to the Clinical Rehabilitation Hospital, Iasi, Romania, for surgery. The control group comprised 30 healthy individuals. Serum levels of interleukin 1α (IL-1α), interleukin 6 (IL-6) and interleukin 8 (IL-8) were measured prior to surgery and were compared among patients with chronic suppurative otitis media (CSOM), cholesteatoma and cholesteatoma recidivism and the control group. High serum levels of interleukins were recorded in all the groups compared to the healthy control group. IL-6 and IL-8 had the highest value in patients with CSOM and IL-1α had the highest value in patients with cholesteatoma recidivism. Thus, we can consider that inflammatory mediators play a central role in the pathogenesis of CSOM and cholesteatoma by maintaining a systemic and local inflammatory response.

Background: We have investigated the main genetic causes for non-syndromic hearing impairment (NSHI) in the hearing impairment individuals from the North-Eastern Romania and proposed a cost-effective diagnosis protocol. Methods: MLPA followed by Sanger Sequencing were used for all 291 patients included in this study. Results: MLPA revealed abnormal results in 141 cases (48.45%): 57 (40.5%) were c.35delG homozygous, 26 (18.44%) were c.35delG heterozygous, 14 (9.93%) were compound heterozygous and 16 (11.35%) had other types of variants. The entire coding region of GJB2 was sequenced and out of 150 patients with normal results at MLPA, 29.33% had abnormal results: variants in heterozygous state: c.71G>A (28%), c.457G>A (20%), c.269T>C (12%), c.109G>A (12%), c.100A>T (12%), c.551G>C (8%). Out of 26 patients with c.35delG in heterozygous state, 38.46% were in fact compound heterozygous. Conclusions: We identified two variants: c.109G>A and c.100A>T that have not been reported in any study from Romania. MLPA is an inexpensive, rapid and reliable technique that could be a cost-effective diagnosis method, useful for patients with hearing impairment. It can be adaptable for the mutation spectrum in every population and followed by Sanger sequencing can provide a genetic diagnosis for patients with different degrees of hearing impairment.

Quality of life is a widely used concept that tends to become an important part of clinical management. The present study performs an analysis of the impact of suppurative chronic otitis media with and without cholesteatoma on quality of life, using the COMQ-12 questionnaire. It was applied to a group of 40 healthy people and to 40 patients before surgery, and the answers to the questions were analyzed and correlated with socioeconomic factors. After the confirmation of the diagnosis based on clinical and imaging information, the patients completed the COMQ-12 questionnaire. It was observed that the chronic ear problems had negative impacts of varying degrees on daily and long-term activities. The evaluation and analysis of information can be used in setting therapeutic targets.

Ménière’s disease is an idiopathic disorder of the inner ear whose causes and pathogenetic mechanisms remain insufficiently elucidated. Advances in genetic analysis technologies have shifted attention toward the role of hereditary components in Ménière’s disease, generating a considerable number of studies investigating the relationship between human genetic variations and disease onset. The results of these investigations highlight the complex and heterogeneous nature of pathogenesis, involving both genetic and epigenetic alterations. Studies have identified multiple candidate genes involved in the regulation of endolymphatic fluid homeostasis, immune response, control of oxidative stress, and maintenance of the structural integrity of the inner ear. However, the reproducibility of these associations varies substantially across populations, reflecting the impact of ethnic heterogeneity, HLA haplotypes, and phenotypic diversity among patients. Moreover, non-genetic factors may act as triggers or modulators of the disease in genetically predisposed individuals. Taken together, the evidence supports a polygenic and context-dependent model of the disorder, in which genes influence susceptibility but do not directly determine disease development. Integrating genomic information with clinical data, analyzing immunological profiles, and investigating exposure to environmental factors are essential steps for patient classification and for the development of individualized treatment strategies.

Food security and food safety are major aspects for human and animal health, yet mycotoxins contaminate 60–80% of food crops before and after harvest, elevating the risk of chronic toxicity and cancer development. This study investigates the potential of ferulic acid (FA) as an antioxidant against mycotoxin-induced oxidative stress in Caco-2 cells exposed to aflatoxin B1 (AFB1) and ochratoxin A (OTA) for 24 and 48 h. The effects on the degree of lipid peroxidation and non-enzymatic and enzymatic mechanisms against oxidative stress were evaluated. FA appears to mitigate oxidative stress by modulating lipid and protein oxidation, decreasing the level of 4-hydroxy-2-nonenal (4-HNE), increasing superoxide dismutase (SOD) activity, and preserving thiol groups by scavenging reactive oxygen species (ROS). Additionally, the reduction in polyubiquitinated Nrf2 level, and higher SOD activity, suggest that FA stabilizes Nrf2, delaying its degradation and reinforcing its antioxidant role. These findings indicate that FA partially counteracts mycotoxin-induced oxidative damage, highlighting the need for further investigation into its long-term effects.

Hearing loss is a major health burden, often caused by ototoxic drugs such as cisplatin and gentamicin. Effective therapy is limited by the poor penetrability of drugs into inner ear compartments. This study aimed to develop and test magnetic cationic liposomes as nanocarriers for targeted corticosteroid delivery to auditory hair cells. Carboxymethyl chitosan–coated liposomes were prepared by the lipid film hydration method, incorporating magnetic nanoparticles and dexamethasone phosphate in their aqueous core. The optimal liposomal formulation, in terms of size, zeta potential, and drug leakage over time, was selected and tested in an in vitro model of drug-induced ototoxicity. HEI-OC1 cells exposed to cisplatin or gentamicin were co-treated with the liposomal formulations, and viability, mitochondrial membrane potential, and β-galactosidase activity were assessed. The results demonstrated that magnetic, polymer-coated liposomes protected against cytotoxicity by preserving mitochondrial function and significantly reducing senescence. These findings provide a proof of concept for magnetically responsive liposomal systems as potential therapeutic platforms for preventing or treating drug-associated hearing loss.

Hearing loss affects millions worldwide and is driven by diverse etiologies, including genetic mutations, ototoxic drug exposure, noise trauma, and aging. To investigate underlying mechanisms and test potential therapies, in vitro models, such as immortalized auditory hair cell lines, cochlear explants, and inner ear organoids, have become indispensable. However, these models face limitations in physiological relevance, scalability, and reproducibility. Recent advances in computer modeling, machine learning (ML), and deep learning (DL) offer powerful tools to enhance the accuracy, efficiency, and translational potential of these systems. This review explores the current state of integration of artificial intelligence algorithms into in vitro auditory models, highlighting its applications in high-throughput image analysis, predictive modeling of ototoxicity, optimization of culture conditions, and organoid development. Furthermore, AI-enabled tools for analyzing omics data, segmenting cochlear structures, and modeling genetic forms of deafness are presented. Despite promising developments, challenges persist, including data standardization, biological complexity, and model interpretability. Addressing these issues through improved datasets, explainable AI, and clinical integration will be key to harnessing AI’s full potential for advancing auditory research and precision medicine.

Background and objectives: Knowledge of the interactions and influences of infectious, genetic, and environmental factors on the evolution and treatment response of malignant tumors is essential for improving the management of the disease and increasing patient survival. The objective of this study was to establish the contribution of human papillomavirus (HPV), as well as p53 and p16 tumor markers, alongside associated factors (smoking and alcohol consumption), in the progression of malignancies located in the oropharynx and at the retromolar trigone–oropharyngeal junction. Materials and Methods: We performed a prospective study including 50 patients with malignant tumors of the oropharynx and retromolar trigone–oropharyngeal junction. In all patients, the presence and type of HPV were determined, as well as the status of the tumor markers p53 and p16. The associated risk factors, biopsy results, treatment method, and post-treatment evolution were all documented. Statistical analyses were performed to evaluate the correlations between the determining factors and their influence on the post-treatment evolution. An overall increased survival rate was found in HPV(+) patients. Results: Our study outlined the prevalence of different high-risk subtypes of HPV from the ones presented by other studies, suggesting a possible geographic variation. Correlations between the p53 and p16 statuses and patient survival could be established. The association of smoking and alcohol consumption strongly correlated with an unfavorable evolution. Conclusions: Awareness of the differences in the post-treatment evolution of the patients in relation to the presence of the factors determined in our study could change the future management of such cases for ensuring improved treatment outcomes.
