Lung cancer (LC) and malignant mesothelioma (MM) are malignancies linked to environmental/occupational exposure, which are increasing in incidence. Despite advances in chemotherapy, radiation therapy and surgical management of LC and MM, the median survival remains less than 12 months. Early detection represents one of the most promising approaches to reducing the growing cancer burden by increasing chemotherapy treatment efficiency. At present, early diagnosis is rather difficult and depends on invasive sampling of pleural fluid or tissue. Currently the most widely used screening method for the surveillance of exposed subjects is computed tomography (CT), which is costly, exposes patients to repeated high doses of radiation, and typically detects the malignancy at its advanced stage. Recently, a virtually non-invasive 'liquid biopsy' has emerged as source to characterize tumour heterogeneity. The genetic/epigenetic changes during tumour evolution can be detected in fluids and used as cancer biomarkers. Therefore, increasingly interest has been paid to circulating (cell-free) nucleic acids (cfDNA/cfmiRNAs) epigenetically modulated during cell transformation. Hypermethylation of tumour suppressor genes is frequently observed in cancers, and such epigenetic changes are potential markers for detecting and monitoring tumours. The same predictive biomarkers can be used as therapy targets.

Sarcopenic obesity (SO) is a body composition phenotype derived from the simultaneous presence in the same individual of an increase in fat mass and a decrease in skeletal muscle mass and/or function. Several protocols for the diagnosis of SO have been proposed in the last two decades making prevalence and disease risk estimates of SO heterogeneous and challenging to interpret. Dementia is a complex neurological disorder that significantly impacts patients, carers and healthcare systems.

Background: Vulvodynia is a multifactorial disease affecting 7%-16% of reproductive-aged women in general population; however, little is still known about the genetics underlying this complex disease.
Aim: To compare polygenic risk scores for hormones and receptors levels in a case-control study to investigate their role in vulvodynia and their correlation with clinical phenotypes.
Methods: Our case-control study included patients with vestibulodynia (VBD) and healthy women.

BACKGROUND Cowden syndrome is a genetic disorder that predisposes individuals to cancer and is characterized by hamartomas derived from 3 germ layers. Although the clinical signs can be pathognomonic, diagnosis is often aided by biopsies, histopathological examination of oral and cutaneous lesions, and genetic studies, including multiple ligation-dependent probe amplification (MLPA). CASE REPORT We report a case of a 35-year-old woman who manifested with multiple lesions in the buccal mucosa, dorsum of the tongue, and gums, along with papillomatous papules on her facial skin and the dorsal surfaces of her hands.

Background: The growing demand for healthcare services challenges patient flow management in health systems. Alternative Level of Care (ALC) patients who no longer need acute care yet face discharge barriers contribute to prolonged stays and hospital overcrowding. Predicting these patients at admission allows for better resource planning, reducing bottlenecks, and improving flow.

Purpose: To enhance the detection rate of Neonatal Intrahepatic Cholestasis caused by Citrin Deficiency (NICCD) through newborn screening (NBS), we analyzed the metabolic profiles of missed patients and proposed a more reliable method for early diagnosis.
Methods: In this retrospective study, NICCD patients were classified into "Newborn Screening" (64 individuals) and "Missed Screening" (52 individuals) groups. Metabolic profiles were analyzed using the non-derivatized MS/MS Kit, and genetic mutations were identified via next-generation sequencing and confirmed by Sanger sequencing.
