Tissue Engineering Construct for Articular Cartilage Restoration with Stromal Cells from Synovium vs. Dental Pulp-A Pre-Clinical Study.

Background/objectives: Cartilage injuries and osteoarthritis are prevalent public health problems, due to their disabling nature and economic impact. Mesenchymal stromal cells (MSCs) isolated from different tissues have the immunomodulatory capacity to regulate local joint environment. This translational study aims to compare cartilage restoration from MSCs from the synovial membrane (SM) and dental pulp (DP) by a tissue-engineered construct with Good Manufacturing Practices.

Dietary habits, lifestyles, and overall adherence to 2018 WCRF/AICR cancer prevention recommendations among adult women in the EPIC-Florence cohort: Changes from adulthood to older age and differences across birth cohorts.

Objectives, Setting And Participants: We aimed to examine changes in dietary habits, lifestyles (e.g., smoking, physical activity levels, and alcohol intake), anthropometry, other individual health-relevant characteristics, and overall adherence to 2018 WCRF/AICR cancer prevention recommendations, among women enrolled in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Florence cohort.

Cigarette smoking and mammographic breast density in post-menopausal women from the EPIC Florence cohort.

Introduction: Cigarette smoking has been recognized as a risk factor for breast cancer (BC) also if the biological mechanism remains poorly understood. High mammographic breast density (MBD) is associated with BC risk and many BC risk factors, such as genetic, anthropometric, reproductive and lifestyle factors and age, are also able to modulate MBD. The aim of the present study was to prospectively explore, in post-menopausal women, the association between smoking habits and MBD, assessed using an automated software, considering duration and intensity of smoking.

How to direct patients to high-volume hospitals: exploring the influencing drivers.

Background: During the last decade, planning concentration policies have been applied in healthcare systems. Among them, attention has been given to guiding patients towards high-volume hospitals that perform better, acccording to the volume-outcome association. This paper analyses which factors drive patients to choose big or small hospitals (with respect to the international standards of volumes of activity).

Use and misuse of the emergency room by patients with eating disorders in a matched-cohort analysis: What can we learn from it?

We examined the pattern of access to hospital emergency room (hER) in 2018-2021 among patients with eating disorders (ED) from Florence, Italy, diagnosed during 1994-2018, using a matched cohort design. We included 902 ED patients and an equal number of sex-, age-, and residence-matched individuals. We fitted conditional Poisson regression models with robust variance estimator to estimate incidence rate ratios (IRR) and 95% confidence intervals.

Lifetime changes in body fatness and breast density in postmenopausal women: the FEDRA study.

Background: High mammographic breast density (MBD) is an established risk factor for breast cancer (BC). Body fatness conveys an increased BC risk in postmenopause but is associated with less dense breasts. Here, we studied the relationship between body fatness and breast composition within the FEDRA (Florence-EPIC Digital mammographic density and breast cancer Risk Assessment) longitudinal study.

The FEDRA Longitudinal Study: Repeated Volumetric Breast Density Measures and Breast Cancer Risk.

Mammographic breast density (MBD) is a strong independent risk factor for breast cancer (BC). We investigated the association between volumetric MBD measures, their changes over time, and BC risk in a cohort of women participating in the FEDRA (Florence-EPIC Digital mammographic density and breast cancer Risk Assessment) study. The study was carried out among 6148 women with repeated MBD measures from full-field digital mammograms and repeated information on lifestyle habits, reproductive history, and anthropometry.

Association between Alcohol Intake and Prostate Cancer Mortality and Survival.

We conducted a systematic review and meta-analysis to investigate the role of alcohol consumption with the prognosis of prostate cancer (PCa). Published reports were gathered on 15 October 2022, from PUBMED/MEDLINE and EMBASE. We found 19 independent eligible studies on the association between consumption of alcoholic beverages and the risk of fatal PCa (n = 5), PCa mortality (n = 5) in healthy subjects, and PCa patients' survival (n = 7) or surrogates thereof (n = 2).

The clinical impact of continued smoking in patients with breast and other hormone-dependent cancer: A systematic literature review.

We conducted a systematic review of studies that investigated whether quitting smoking at or around diagnosis improves survival of patients with hormone-dependent cancers (HDC). Nine studies published in 2013-2022 were included. Studies were very diverse in terms of design, definition of quitters and continued smokers, and prevalence of prognostic factors other than smoking cessation (e.

Dietary Patterns, Dietary Interventions, and Mammographic Breast Density: A Systematic Literature Review.

Background: Breast cancer (BC) is the most common and deadliest malignancy among women. High mammographic breast density (MBD) is an established modifiable risk marker for BC, and it is of interest, for prevention purposes, to consider lifestyle factors that may modulate both MBD and BC risk. Here, we conducted a systematic review of the most up-to-date evidence on the association between diet as a whole and MBD.

A Priori Dietary Patterns, Physical Activity Level, and Body Composition in Postmenopausal Women: A Cross-Sectional Study.

Midlife weight gain and fat distribution changes increase the risk of age-related pathologies. We aimed to explore, in a series of 388 healthy postmenopausal women living in Tuscany, Central Italy, the relationship between three dietary patterns, the level of physical activity (PA), and four body composition measures: body mass index (BMI), percent fat mass (%FM), percent muscle mass (%MM), and waist circumference (WC). Detailed information on lifestyle, including the amount of recreational and household PA, sitting time, and dietary habits were collected through detailed questionnaires, and adherence scores to Greek Modified Mediterranean Diet, Italian Mediterranean Diet (IMD), and Dietary Approaches to Stop Hypertension diet were calculated.

Fish Consumption and Colorectal Cancer Risk: Meta-Analysis of Prospective Epidemiological Studies and Review of Evidence from Animal Studies.

: Epidemiological studies on the association between fish consumption and colorectal cancer (CRC) risk have yielded inconsistent results, despite evidence from preclinical studies that long-chain ω-3 polyunsaturated fatty acids inhibit colorectal carcinogenesis. We conducted a meta-analysis of prospective epidemiological studies investigating the association between fish consumption and CRC risk among humans and reviewed studies examining the link between fish components and colorectal carcinogenesis in animal models. : We included studies published until November 2020.

Hospital volume allocation: integrating decision maker and patient perspectives.

Planning problems in healthcare systems have received greater attention in the last decade, especially because of the concerns recently raised about the scattering of surgical interventions among a wide number of different facilities that can undermine the quality of the outcome due to the volume-outcome association. In this paper, an approach to plan the amount of surgical interventions that a facility has to perform to assure a low adjusted mortality rate is proposed. The approach explicitly takes into account the existing interaction among patients' choices and decision makers' planning decisions.

Oncological outcomes in oncoplastic breast surgery: a single institution analysis.

Oncoplastic surgery is a well-acknowledged technique that combines conserving treatment in breast cancer with plastic surgery reconstruction. The aim of our analysis is to evaluate the safety of this surgical procedure in the setting of invasive primary breast cancer, and then compare breast oncoplastic surgery with the Veronesi quadrantectomy.We have analyzed 1541 patients who underwent breast surgery for primary breast tumor between October 2004 and May 2018 at Sant'Andrea University Hospital in Rome: 880 women experienced the breast oncoplastic approach, while 660 patients received conservative surgery alone.

Positive margins (R1) risk factors in breast cancer conservative surgery.

Background: The primary goal in conservative breast cancer surgery is the complete excision of the tumor, but at the same time attempting to obtain a satisfactory postoperative esthetic result. The notion of "No Ink on Tumor" that indicates exclusively the presence of tumor cells on the inked surface of the surgical specimen is now the gold standard; however, the problem of the free margin is still a fundamental topic of debate that has not yet found a definitive solution.

Methods: Our retrospective analysis takes into account 1440 patients undergoing breast conservative surgery, from October 2004 to November 2018, all treated at the breast unit of our institution.

Composition of personalized and standard nutritional mixtures in patients on home parenteral nutrition.

Background/objectives: The compounding of personalized parenteral nutrition mixtures (PPNMs) for home parenteral nutrition (HPN) gives the possibility to better satisfy nutritional requirements for patients in selected clinical conditions. The objective of this study was to compare the composition of PPNMs prescribed in selected cases, by a practitioner nutritionist, with that of industrially manufactured standard parenteral nutrition mixtures (SPNMs).

Subjects/methods: Two hundred and ninety-eight patients (151 men, 147 women, aged 17-87 years) on HPN, followed up in 2011 at our Center, were retrospectively recruited.

Time-frequency analysis of the endocavitarian signal in paroxysmal atrial fibrillation.

We apply the time-frequency analysis to the endocavitarian signal of patients suffering from paroxysmal atrial fibrillation. The time-frequency spectrum reveals the components of the endocavitarian signal. These components are located in the regions of the time-frequency domain that differ for in-rhythm and in-atrial fibrillation signals.

Recognizing myofascial pelvic pain in the female patient with chronic pelvic pain.

Myofascial pelvic pain (MFPP) is a major component of chronic pelvic pain (CPP) and often is not properly identified by health care providers. The hallmark diagnostic indicator of MFPP is myofascial trigger points in the pelvic floor musculature that refer pain to adjacent sites. Effective treatments are available to reduce MFPP, including myofascial trigger point release, biofeedback, and electrical stimulation.

Role of EGFR family receptors in proliferation of squamous carcinoma cells induced by wound healing fluids of head and neck cancer patients.

Background: Mounting evidence suggests that recurrence of resected head and neck squamous cell carcinomas (HNSCCs) is due to the outgrowth of unrecognized residual tumor cells as well as to the premalignant and/or precursor-field epithelial cells. We studied the impact of processes triggered by HNSCC surgery in stimulating both residual tumor cells [demonstrated to overexpress epidermal growth factor receptor (EGFR)], and premalignant cells surrounding the resected lesion.

Patients And Methods: EGFR expression/activation by immunohistochemistry/biochemistry and gene status by FISH were investigated in 23 primary HNSCCs and surrounding tissues.

Interleukin-6 and Mycoplasma hominis as markers of preterm birth and related brain damage: our experience.

Objective: The aim of this study is to investigate whether a high concentration of interleukin-6 (IL)-6 in the amniotic fluid is associated to a higher risk of preterm delivery, premature rupture of the membranes (PROM), and periventricular leucomalacia (PVL) in preterm infants; we have further investigated whether the levels of IL-6 are related to the presence of vaginal infection by mycoplasms.

Methods: One hundred eight patients were screened by vaginal swab, sonography, amniocentesis, and dosage of IL-6 in the amniotic fluid during the second trimester of pregnancy.

Results: High levels of IL-6 and vaginal mycoplasms are related to preterm birth and PROM.

Polymorphisms of Metabolizing Enzymes and Susceptibility to Ethmoid Intestinal-type Adenocarcinoma in Professionally Exposed Patients.

Intestinal-type adenocarcinoma (ITAC) of ethmoid is a rare tumor associated with occupational exposure to wood and leather dusts. Polymorphisms in xenobiotic metabolizing enzymes play an important role in gene-environment interactions and may contribute to a high degree of variance in individual susceptibility to cancer risk. The aim of this study was to investigate by polymerase chain reaction the role of polymorphisms at CYP1A1 and GSTM1 genes in 30 ethmoid ITAC patients and 79 healthy donors.

PDGFRA, PDGFRB, EGFR, and downstream signaling activation in malignant peripheral nerve sheath tumor.

We investigated the activation of platelet-derived growth factor (PDGF) receptor A (PDGFRA), PDGF receptor B (PDGFRB), epidermal growth factor receptor (EGFR), and their downstream pathways in malignant peripheral nerve sheath tumors (MPNSTs). PDGFRA, PDGFRB, and EGFR were immunohistochemically, biochemically, cytogenetically, and mutationally analyzed along with the detection of their cognate ligands in 16 neurofibromatosis type 1 (NF1)-related and 11 sporadic MPNSTs. The activation of the downstream receptor pathways was also studied by means of v-akt murine thymoma viral oncogene homolog (AKT), extracellular signal-regulated kinase (ERK), and mammalian target of rapamycin (mTOR) Western blotting experiments, as well as rat sarcoma viral oncogene homolog (RAS), v-raf murine sarcoma viral oncogene homolog B1 (BRAF), phosphoinositide-3-kinase, catalytic, alpha polypeptide (PI3KCA), and phosphatase and tensin homolog deleted on chromosome ten (PTEN) mutational analysis and fluorescence in situ hybridization.

Cyclooxygenase-2 and platelet-derived growth factor receptors as potential targets in treating aggressive fibromatosis.

Purpose: To explore the molecular bases of potential new pharmacologic targets in aggressive fibromatosis (desmoid tumor).

Experimental Design: Tumor specimens from 14 patients surgically treated for aggressive fibromatosis (6 familial adenomatous polyposis and 8 sporadic cases), analyzed for adenomatous polyposis coli (APC) and CTNNB1 (beta-catenin) mutations, were further investigated for beta-catenin, cyclooxygenase-2 (COX-2), platelet-derived growth factor (PDGF) receptor alpha (PDGFRA)/PDGF receptor beta (PDGFRB), their cognate ligands (PDGFA and PDGFB), and KIT using a comprehensive immunohistochemical, biochemical, molecular, and cytogenetic approach.

Results: No CTNNB1 (beta-catenin) mutations were found in the familial adenomatous polyposis patients, but previously reported activating mutations were found in six of the eight sporadic patients.
