Evaluation of Skin Melanoma in Spectral Range 450-950 nm Using Principal Component Analysis

2013

Diagnostic potential of principal component analysis (PCA) of multi-spectral imaging data in the wavelength range 450-950 nm for distant skin melanoma recognition is discussed. Processing of the measured clinical data by means of PCA resulted in clear separation between malignant melanomas and pigmented nevi.

Risk factors for postoperative morbidity following appendectomy in the elderly: a nationwide prospective cohort study

2019

Background: A limited number of studies investigating perioperative risk factors associated with emergency appendectomy in elderly patients have been published to date. Whether older age may be associated with poorer outcomes following appendectomy is still a matter of debate. The primary aim of this study was to determine the predictors of postoperative morbidity following appendectomy in patients aged ≥ 65 years. Methods: Data regarding all elderly patients who underwent emergency appendectomy from January 2017 to June 2018 admitted 36 Italian surgical departments were prospectively collected and analyzed. Baseline demographics and perioperative variables were evaluated. Uni- and multivar…

Clinical utility of antigen carbohydrate 125 for planning the optimal length of stay in acute heart failure.

2021

BACKGROUND: The optimal length of stay (LOS) in patients hospitalized for acute heart failure (AHF) remains controversial. Plasma antigen carbohydrate 125 (CA125) has emerged as a reliable proxy of congestion. We aimed to evaluate whether there is a differential impact of LOS on the risk of 6-month AHF readmission across CA125 levels. METHODS: This is a retrospective study that included 1,387 patients discharged for AHF in two third-level centers. CA125 was measured 48±24h after admission. The association between CA125 and LOS with the risk of subsequent AHF readmission at 6 months was analyzed by Cox regression analysis accounting for death as a competing event. RESULTS: The median (IQR) a…

Laparoscopic versus robotic right colectomy with extra-corporeal or intra-corporeal anastomosis: a systematic review and meta-analysis.

2020

Purpose: The aim of the present systematic review and meta-analysis is to compare laparoscopic right colectomy (LRC) versus robotic right colectomy (RRC) using homogeneous subgroup analyses for extra-corporeal anastomosis (EA) and intra-corporeal anastomosis (IA). Methods: MEDLINE, Scopus, and Web of Science databases were searched up to April 2020 for prospective or retrospective studies comparing LRC versus RRC on at least one short- or long-term outcome. The primary outcome was the length of hospital stay (LOS). The secondary outcomes included operative and pathological results, survival, and total costs. LRC and RRC were compared using three homogeneous subgroups: without distinction by…

Risk of Parkinson disease in women: Effect of reproductive characteristics

2004

Objective: To investigate the association between some fertile life characteristics and Parkinson disease (PD) in women. Methods: Women affected by PD and control subjects were matched one to one by age (±2 years). One hundred thirty-one women with idiopathic PD and 131 matched control subjects were interviewed. Controls were randomly selected from the resident list of the same municipality of residence of cases. All subjects had a Mini-Mental State Examination score of ≥24. Cumulative length of pregnancies, age at menarche, age and type of menopause, and estrogen use before and after menopause were investigated in cases and controls through a structured questionnaire. Models of matched pai…

Beneficial Effect of Foot Plantar Stimulation in Gait Parameters in Individuals with Parkinson’s Disease

2020

New treatments based on peripheral stimulation of the sensory-motor system have shown to be promising in rehabilitation strategies for patients with neurological disorders, including Parkinson's disease (PD), especially in regards to reducing gait impairment, and hence, the incidence of falls. The aim of this study was to evaluate the change in several gait parameters measured by sensor inertial measurement in PD patients after acute plantar stimulation, under the distal phalanx of the big toe, and underneath the head of the first metatarsal joint of both feet, using a 3D printing insole. In order to assess whether the effects are selective for PD patients, we compared the effect of the tre…

The Effect of Simulated Leg-Length Discrepancy on the Dynamic Parameters of the Feet during Gait—Cross-Sectional Research

2021

Background: The effect of Leg-Length Discrepancy (LLD) on dynamic gait parameters has been extensively discussed. Podobarography is the study of foot-to-ground pressure distribution. It has been used to test plantar footprint deviations that could reveal pathology. Purpose: The aim of this study is to determine the effects of simulated LLD on dynamic gait parameters measured with a pressure platform in healthy subjects. Methods: Thirty-seven healthy subjects participated in observational cross-sectional research. A procedure was performed to capture the dynamic parameters of each participant under five different simulated LLD conditions. Support time, mean pressure, and peak pressure measur…

Time trends, sociodemographic and health factors associated with discharge and length of stay of hospitalised patients with sickle cell disease in Gh…

2021

ObjectivePatients with sickle cell disease (SCD) are prone to multiple episodes resulting in frequent hospital visits. We determined the time trends, sociodemographic and health factors associated with length of stay (LoS) for patients with SCD in Ghana.Design, participants, settingWe retrospectively analysed SCD hospitalisation records of 22 680 patients from a nationwide database of the Ghana Health Service from 2012 to 2017.Outcome measuresFactors associated with LoS were estimated using Cox regression, while the cumulative incidence of being discharged alive was estimated with in-hospital death as a competing risk.ResultsPatients admitted for SCD over 6 years constituted 22 680 (0.8%) o…

Muscle architecture is an important component of muscle function, and recent studies have shown changes in muscle architecture with fatigue. The stretch-shortening cycle is a natural way to study human locomotion, but little is known about how muscle architecture is affected by this type of exercise. This study investigated potential changes in medial gastrocnemius (MG) muscle architecture after exhaustive stretch-shortening cycle exercise. Male athletes (n = 10) performed maximal voluntary contractions (MVC) and maximal drop jump (DJ) tests before and after an exercise task consisting of 100 maximal DJs followed by successive rebound jumping to 70% of the initial maximal height. The exerci…

The effect of gestational age and cervical length measurements in the prediction of spontaneous preterm birth in twin pregnancies : an individual pat…

2016

OBJECTIVE: To assess the effect of gestational age (GA) and cervical length (CL) measurements at transvaginal ultrasound (TVUS) in the prediction of preterm birth in twin pregnancy. DESIGN: Individual patient data (IPD) meta-analysis. SETTING: International multicentre study. POPULATION: Asymptomatic twin pregnancy. METHODS: MEDLINE and EMBASE searches were performed and IPD obtained from authors of relevant studies. Multinomial logistic regression analysis determined probabilities for birth at ≤28(+0) , 28(+1) to 32(+0) , 32(+1) to 36(+0) , and ≥36(+1) weeks as a function of GA at screening and CL measurements. MAIN OUTCOME MEASURES: Predicted probabilities for preterm birth at ≤28(+0) , 2…
