Time-Restricted Feeding and Metabolic Outcomes in a Cohort of Italian Adults.
2021
Background: research exploring the effects of food timing and frequency on health and disease is currently ongoing. While there is an increasing body of scientific literature showing the potential health benefits of intermittent fasting (IF) in laboratory settings and in animals, studies regarding IF on humans are limited. Therefore, the objective of this research was to evaluate the relationship between the feeding/fasting time window and metabolic outcomes among adult individuals. Methods: dietary and demographic data of 1936 adult subjects living in the south of Italy were examined. Food frequency questionnaires (FFQ) were administered to determine the period of time between the first an…
Diagnosis and Classification of 17 Diseases from 1404 Subjects via Pattern Analysis of Exhaled Molecules.
2016
We report on an artificially intelligent nanoarray based on molecularly modified gold nanoparticles and a random network of single-walled carbon nanotubes for noninvasive diagnosis and classification of a number of diseases from exhaled breath. The performance of this artificially intelligent nanoarray was clinically assessed on breath samples collected from 1404 subjects having one of 17 different disease conditions included in the study or having no evidence of any disease (healthy controls). Blind experiments showed that 86% accuracy could be achieved with the artificially intelligent nanoarray, allowing both detection and discrimination between the different disease conditions examined.…
Uncertainty quantification in simulations of epidemics using polynomial chaos.
2012
Mathematical models based on ordinary differential equations are a useful tool to study the processes involved in epidemiology. Many models consider that the parameters are deterministic variables. But in practice, the transmission parameters present large variability and it is not possible to determine them exactly, and it is necessary to introduce randomness. In this paper, we present an application of the polynomial chaos approach to epidemiological mathematical models based on ordinary differential equations with random coefficients. Taking into account the variability of the transmission parameters of the model, this approach allows us to obtain an auxiliary system of differential equa…
Early detection of Toxoplasma infection by molecular monitoring of Toxoplasma gondii in peripheral blood samples after allogeneic stem cell transplan…
2004
International audience; Background. Isolated case reports have shown that recipients of allogeneic hematopoietic stem cell transplants ( HSCTs) who develop toxoplasmosis may have circulating Toxoplasma gondii DNA in peripheral blood before the onset of clinical symptoms. Methods. We prospectively studied 106 T. gondii - seropositive adult recipients of HSCTs for the incidence of reactivation of toxoplasmosis in the first 6 months after transplantation. Toxoplasmosis infection ( TI) was defined by a positive result of polymerase chain reaction ( PCR) of peripheral blood specimens, whereas toxoplasmosis disease ( TD) was defined as an invasive infection. Results. The incidence of TI was 16% (…
Halloysite/Keratin Nanocomposite for Human Hair Photoprotection Coating
2020
We propose a novel keratin treatment of human hair by its aqueous mixtures with natural halloysite clay nanotubes. The loaded clay nanotubes together with free keratin produce micrometer-thick protective coating on hair. First, colloidal and structural properties of halloysite/keratin dispersions and the nanotube loaded with this protein were investigated. Above the keratin isoelectric point (pH = 4), the protein adsorption into the positive halloysite lumen is favored because of the electrostatic attractions. The ζ-potential magnitude of these core-shell particles increased from -35 (in pristine form) to -43 mV allowing for an enhanced colloidal stability (15 h at pH = 6). This keratin-cla…
The Rorschach method for obesity assessment: clinical study on a group of obese women
2018
SUMMARY. Aim. The purpose of this study is to explore through the Rorschach method the psychological and personological profile of the woman with obesity. Methods. The Rorschach test was administered to 10 women with body mass index of 41.86±9.9 kg/m2 at the clinic for obesity surgical treatment at the University Hospital “Paolo Giaccone” of Palermo. Results. The quantitative and qualitative analysis of the Rorschach responses detected in the study show: limited practical and creative sense in managing daily life situations, rigid control of emotions, affective turmoil, sense of inadequacy; sufficient examination of reality and adaptation social. Conclusion. The Rorschach method can be the …
Analysis of Selected Body Composition Parameters and Ergonomic Safety among Professionally Active Nurses in Poland: A Preliminary Prospective Monocen…
2020
Nurses consist of an occupational group that is particularly exposed to harmful work-related factors such as prolonged working hours, severe stress, fatigue, and excessive strain on the musculoskeletal system. According to nurses, the limitation of the application of ergonomic principles of work may contribute to the occurrence of numerous dangerous behaviors, improper eating habits, or deficiency of systematic physical activity. The most common consequences are nutritional disorders and musculoskeletal system dysfunctions. This prospective observational study was aimed at evaluating selected parameters of the body composition of professionally active nurses and at determining work-related …
Effect of obesity on disease-free and overall survival in node-positive breast cancer patients in a large French population: A pooled analysis of two…
2014
Abstract Background To examine the association between baseline body mass index (BMI), and disease-free survival (DFS) and overall survival (OS) in a large French early-stage breast cancer population included in the UNICANCER Programme d’Action Concerte Sein-01 (PACS01) and PACS04 phase III randomised trials. Methods After a median follow-up of 5.9 years, this report analyses 4996 patients with node-positive breast cancer, and randomly assigned to adjuvant anthracycline-based chemotherapy combined or not with taxanes. Univariate analyses were used to study the effects of well known prognostic factors and BMI on DFS and OS. BMI was obtained at baseline, before chemotherapy initiation, and ob…
Increasing adiposity in normal ovulatory women affects adipocytokine expression in subcutaneous and visceral abdominal fat
2008
Abstract Objective To determine which adipocytokines are differentially expressed as a function of body mass index (BMI), to compare expression of adipocytokines in abdominal subcutaneous and omental fat, and to correlate these findings with serum levels, BMI, and parameters of insulin resistance. Methods Serum and subcutaneous (sc) and omental (om) tissue were obtained from lean and obese ovulatory women undergoing gynecologic surgery. We determined adipocytokine expression in sc versus om abdominal fat and related this to increasing BMI. Results Serum leptin was higher and adiponectin lower in overweight subjects. Adipocytokines had higher expression in sc abdominal versus om adipose tiss…
Influence of sociocultural factors on the ovulatory status of polycystic ovary syndrome.
2009
OBJECTIVE: To evaluate the role of social and cultural differences inside the same ethnic group on the ovulatory status of women with polycystic ovary syndrome (PCOS). DESIGN: To correlate social and cultural status with the phenotypic expression (body weight and ovulation) and with androgen and insulin levels of PCOS. SETTING: University department of medicine. PATIENT(S): Two hundred and forty-four consecutive PCOS women. INTERVENTION(S): All studied patients completed a simple questionnaire to indicate their mean family income and their school education. MAIN OUTCOME MEASURE(S): Ovulation was assessed by measurement of serum progesterone on day 22 of a spontaneous or induced menstrual cy…
