Simulation for training in sinus floor elevation: new surgical bench model

2011

Objectives: to describe a bench model (workshop of abilities) for sinus floor elevation (SFE) training that simulates the surgical environment and to assess its effectiveness in terms of trainees’ perception. Study design: thirty-six randomly selected postgraduate students entered this cross-sectional pilot study and asked to fill in an anonymous, self-applied, 12-item questionnaire about a SFE workshop that included a study guide containing the workshop’s details, supervised practice on a simulated surgical environment, and assessment by means of specific check-lists. Results: Thirtiy-six fresh sheep heads were prepared to allow access to the buccal vestible. Using the facial tuber, third …

Is cell salvage safe in liver resection? A pilot study

2007

Abstract Study Objective To investigate the quality of cell salvaged (CS) blood in patients undergoing hemihepatectomy (study group) and compare it with CS-blood from aortic surgery (control group). Design Observational study. Setting Operating room in a university hospital. Measurements 6 patients undergoing hemihepatectomy or aortobifemoral bypass with intraoperative blood loss of more than 800 mL. Samples were drawn from the central venous catheter, from the reservoir of a CS recovery system, and from the processed blood in each patient to determine interleukin (IL)-6, IL-8, IL-10, tumor necrosis factor (TNF), complement C3a, and the terminal complement complex C5b-9. Microbiological ana…

Predicting survival after transarterial chemoembolization for hepatocellular carcinoma using a neural network: A Pilot Study.

2019

BACKGROUND AND AIMS Deciding when to repeat and when to stop transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC) can be difficult even for experienced investigators. Our aim was to develop a survival prediction model for such patients undergoing TACE using novel machine learning algorithms and to compare it to conventional prediction scores, ART, ABCR and SNACOR. METHODS For this retrospective analysis, 282 patients who underwent TACE for HCC at our tertiary referral centre between January 2005 and December 2017 were included in the final analysis. We built an artificial neural network (ANN) including all parameters used by the aforementioned risk scores a…

GALAD Score Detects Early Hepatocellular Carcinoma in an International Cohort of Patients With Nonalcoholic Steatohepatitis

2020

Background & Aims The prevalence of nonalcoholic steatohepatitis (NASH) associated hepatocellular carcinoma (HCC) is increasing. However, strategies for detection of early-stage HCC in patients with NASH have limitations. We assessed the ability of the GALAD score, which determines risk of HCC based on patient sex; age; and serum levels of α-fetoprotein (AFP), AFP isoform L3 (AFP-L3), and des-gamma-carboxy prothrombin (DCP), to detect HCC in patients with NASH. Methods We performed a case-control study of 125 patients with HCC (20% within Milan Criteria) and 231 patients without HCC (NASH controls) from 8 centers in Germany. We compared the performance of serum AFP, AFP-L3, or DCP vs GALAD …

A novel, fully digital approach to quantifying volume gain after soft tissue graft surgery. A pilot study

2020

Objective Measuring soft tissue thickness after mucogingival surgery has traditionally been performed by means of a calibrated transgingival probe. The main aim of this study was to apply a non-invasive technique based on digital images formatted as Standard Tessellation Language (STL) files to quantify soft tissue volume after connective tissue grafting. Clinical innovation report Ten patients who presented Cairo Class I gingival recession were selected for connective tissue grafting using the tunnel technique. In all patients, the initial position of the gingiva and quantity of keratinized tissue were recorded, and gingival recession was scanned with an intra-oral scanner. Six months afte…

How reproductive and regenerative medicine meet in a Chinese fertility clinic. Interviews with women about the donation of embryos to stem cell resea…

2010

The social interface between reproductive medicine and embryonic stem cell research has been investigated in a pilot study at a large IVF clinic in central China. Methods included observation, interviews with hospital personnel, and five in-depth qualitative interviews with women who underwent IVF and who were asked for their consent to the donation of embryos for use in medical (in fact human embryonic stem cell) research. This paper reports, and discusses from an ethical perspective, the results of an analysis of these interviews. The participants talked of extreme social pressure to become pregnant. Once they had a baby, 'spare' embryos lost practical significance due to the Chinese one-…

Effects of an Educational Program for Professional Caregivers on Behavioral Alterations in Nursing Home Residents: Pilot Study

2020

This pilot study aims to analyze the effectiveness of a type of non-pharmacological intervention such as the educating and training of professional caregivers on behavioral alterations and prescription of psychotropic drugs of older adults in nursing homes. One hundred and forty-five people from two nursing homes were randomized to either treatment (educational training program for healthcare professionals) or a no-treatment group. Twenty-two professional caregivers in the experimental group received 20 h of a training program. Five data collection points were collected (pre and post, and three follow-ups, all six months apart). Intervention consisted of the behavioral alterations and psych…

Add-On Effect of Postural Instructions to Abdominopelvic Exercise on Urinary Symptoms and Quality of Life in Climacteric Women with Stress Urinary In…

2021

The aim of this study was to investigate the add-on effect of postural instructions to an abdominopelvic exercise program on incontinence urinary symptoms (UI symptoms) and quality of life (QoL) in climacteric women with stress urinary incontinence (SUI). A randomized controlled trial was performed with a total of 40 climacteric women with SUI aged between 46 and 75 years old. Participants were randomly assigned to two groups: a group performing an abdominopelvic exercise program (AEP) (n = 20) and a group performing abdominopelvic exercise with the addition of postural instructions (AEPPI) (n = 20). Primary outcome measures were UI symptoms, UI impact and QoL related to UI (UI-QoL), measur…
