Biological, genetic and epigenetic markers in ulcerative colitis.

In this review, we have summarized the existing knowledge of ulcerative colitis (UC) markers based on current literature, specifically, the roles of potential new biomarkers, such as circulating, fecal, genetic, and epigenetic alterations, in UC onset, disease activity, and in therapy response. UC is a complex multifactorial inflammatory disease. There are many invasive and non-invasive diagnostic methods in UC, including several laboratory markers which are employed in diagnosis and disease assessment; however, colonoscopy remains the most widely used method.

Hereditary Cancer Syndrome in a Family with Double Mutation in and Genes.

Hereditary cancer syndromes predispose to several types of cancer due to inherited pathogenic variants in susceptibility genes. We describe the case of a 57-year-old woman, diagnosed with breast cancer, and her family. The proband belongs to a family with a suspected tumor syndrome, due to other cancer cases in her family from the paternal and maternal sides.

Increased Risk of Hereditary Prostate Cancer in Italian Families with Hereditary Breast and Ovarian Cancer Syndrome Harboring Mutations in and in Other Susceptibility Genes.

Hereditary prostate cancer (HPCa) has the highest heritability of any cancer in men. Interestingly, it occurs in several hereditary syndromes, including breast and ovarian cancer (HBOC) and Lynch syndrome (LS). Several gene mutations related to these syndromes have been identified as biomarkers in HPCa.

Antibody levels after BNT162b2 vaccine booster and SARS-CoV-2 Omicron infection.

In the present study, immunogenicity data in 61 vaccinated healthcare workers (HCWs) either infection naïve (naïve HCWs) or with infection of Delta and/or Omicron COVID-19 (experienced HCWs) were evaluated up to 270 days after the second dose of BNT162b2 vaccine and up to 90 days after a booster dose. A decrease in antibody levels at 270 days following administration of the second dose (p = 0.0335) was observed, although values did not fall below the positivity threshold (33.

Pancreatic Cancer with Mutation in BRCA1/2, MLH1, and APC Genes: Phenotype Correlation and Detection of a Novel Germline BRCA2 Mutation.

Pancreatic ductal adenocarcinoma (PDAC) is the seventh leading cause of cancer death worldwide; most of cases are sporadic, however about 5% to 10% report a hereditary predisposition. Several hereditary syndromes have been associated with familial pancreatic cancer (FPC) onset, including hereditary breast and ovarian cancer syndrome (HBOC), Lynch syndrome (LS), Familial atypical multiple mole melanoma (FAMMM), Familial adenomatous polyposis (FAP), Li-Fraumeni syndrome (LFS), Peutz-Jeghers syndrome (PJS), and Hereditary pancreatitis (HP).The aim of this study was to determine the mutational status of a cohort of 56 HBOC families, 7 LS families, 3 FAP and FAMMM families, and 1 LFS family with at least one case of PDAC.

Diagnostic utility of FGF-23 in mineral bone disorder during chronic kidney disease.

Our data confirm that intact fibroblast growth factor 23 (iFGF-23) concentration is increased in patients with chronic kidney disease (CKD) and that it increases with disease progression (stages I-V). Therefore, iFGF-23 could be considered an early biomarker in the course of chronic kidney disease-mineral bone disorder (CKD-MBD), which has several aspects that make it potentially useful in clinical practice. The availability of an automated method for iFGF-23 assay may represent an added value in the management of the patient with CKD-MBD already from the early stages of the disease, before the increase of the routinely used laboratory parameters, 1-84 parathyroid hormone (PTH) and 25-OH-vitamin D (25-OH-vitD), which occur in more advanced stages of the disease.

Evaluation of neutralizing antibodies after vaccine BNT162b2: Preliminary data.

It is well-known that the Coronavirus Disease 2019, which is caused by the beta-coronavirus severe acute respiratory syndrome (SARS-CoV-2), emerged in December 2019 followed by an outbreak first reported in Wuhan, China. Thus far, vaccination appears to be the only way to bring the pandemic to an end. In the present study, immunogenicity data was evaluated using LIAISON® SARS-CoV-2 TrimericS IgG assay (DiaSorin S.

DNA methylation and breast cancer: A way forward (Review).

The current management of breast cancer (BC) lacks specific non‑invasive biomarkers able to provide an early diagnosis of the disease. Epigenetic‑sensitive signatures are influenced by environmental exposures and are mediated by direct molecular mechanisms, mainly guided by DNA methylation, which regulate the interplay between genetic and non‑genetic risk factors during cancerogenesis. The inactivation of tumor suppressor genes due to promoter hypermethylation is an early event in carcinogenesis.

Hereditary Prostate Cancer: Genes Related, Target Therapy and Prevention.

Prostate cancer (PCa) is globally the second most diagnosed cancer type and the most common cause of cancer-related deaths in men. Family history of PCa, hereditary breast and ovarian cancer (HBOC) and Lynch syndromes (LS), are among the most important risk factors compared to age, race, ethnicity and environmental factors for PCa development. Hereditary prostate cancer (HPCa) has the highest heritability of any major cancer in men.

Prevalence of mutations in BRCA and MMR genes in patients affected with hereditary endometrial cancer.

Endometrial cancer (EC) is the fifth most common cancer in women from developed countries, accounting for 4.8% of new cases and 2.1% of deaths.

Five Italian Families with Two Mutations in Genes.

Double heterozygosity (DH) in and genes and double mutation (DM) in or are extremely rare events in the general population, and few cases have been reported worldwide so far. Here, we describe five probands, all women, with breast and/or ovarian cancer and their families. Particularly, we identified two probands with DH in the genes with a frequency of 0.

Double mutation of APC and BRCA1 in an Italian family.

Familial adenomatous polyposis (FAP) is a rare genetic disorder caused mainly by monoallelic mutations of APC gene. The hereditary breast and ovarian cancer (HBOC) syndrome is an autosomal dominantly inherited disease, which mostly predisposes to breast and ovarian cancers as a result of germline mutations in BRCA1 or BRCA2 genes. In a family, mutations in two cancer susceptibility genes are extremely rare.

Risk factors associated with sexually transmitted infections and HIV among adolescents in a reference clinic in Madrid.

Introduction: Adolescents have a higher incidence of sexually transmitted infections (STIs) than persons of older age groups. The WHO emphasises the need to adopt specific and comprehensive prevention programmes aimed at this age group. The objective of this work was to analyse the prevalence of HIV/STIs among adolescents and to identify the sociodemographic, clinical and behavioural markers associated with these infections, in order to promote specific preventive strategies.

BRCA and PALB2 mutations in a cohort of male breast cancer with one bilateral case.

Introduction: Male Breast Cancer (MBC) is a rare disease, about 1% of all breast cancers worldwide and less than 1% of cancers occurring in men. The bilateral male breast cancer (bMBC) is extremely rare. Germline mutations of BRCA1/BRCA2 genes are associated with a significantly increased risk of cancer in MBC; the role of PALB2 remains to be clarified.

and Analysis in FAP Patients: A Novel Mutation in Gene and Genotype-Phenotype Correlation.

and genes are mutated in 70⁻90% and 10⁻30% of familial adenomatous polyposis cases (FAP) respectively. An association between mutation localization and FAP clinical phenotype is reported. The aims of this study were to determine and mutational status in a small cohort of FAP patients and to evaluate the genotype-phenotype correlation in mutated patients.

Cellular and humoral inflammatory response after laparoscopic and conventional colorectal surgery. Preliminary report.

Unlabelled: Our aim is to compare the immune response after colorectal surgery performed laparoscopically and via traditional technique. This response seems to be proportional to the level of the surgical trauma and presumably is directed to improve host defence. This is a prospective reported study based on patients' randomisation.

Double heterozygosity in the BRCA1 and BRCA2 genes in Italian family.

Background: Double heterozygosity (DH) is an extremely rare event in which both BRCA1 and BRCA2 are mutated simultaneously in a family. To date, few cases of DH have been reported, especially in Ashkenazi populations. In Italy some cases of DH have been reported.
