Struggling with Science and Status: Physiotherapy – Including Radiology and Cancer Treatment – and Physical Education at the State University in Ghent,Belgium, 1906–1936

The establishment of new academic specialties is an intriguing research topic from a social history of science perspective. In this article we focus on the ‘scientific migration’ within the Higher Institute of Physical Education (HIPE) and the Faculty of Medicine at the State University in Ghent, Belgium. The HIPE was ‘attached’ to the Faculty of Medicine in 1908, a world first that led to an interesting triangular relationship between physical education, physiotherapy, and medicine. The physiatrists (physicians-physiotherapists) who were appointed at the HIPE had to struggle with inferior status with respect to their colleagues within the Faculty of Medicine itself. Territorial power struggles arose on several levels. In 1936, after the first generation of physicians-physiotherapists had retired, physiotherapy was integrated fully into the Faculty of Medicine, and radiology and cancer treatment – which had been considered subsectors of physiotherapy – became autonomous specialties. Physical education, however, retained its inferior academic status.

Risk of venous thromboembolic disease in postmenopausal women taking oral or transdermal hormone replacement therapy

Objective  

The influence of hormone replacement therapy (HRT) on hemostasis processes depends on the type of hormone, the combination of doses, the time of taking HRT, and the route of administration (oral, transdermal, implanted). The aim of the current study was to assess some parameters of coagulation, especially tissue factor pathway inhibitor (TFPI) and tissue factor (TF) in postmenopausal women using oral or transdermal HRT.     

Polyethylenimine-cyclodextrin-tegafur conjugate shows anti-cancer activity and a potential for gene delivery

Polyethylenimine-cyclodextrin-tegafur (PEI-CyD-tegafur) conjugate was synthesized as a novel multifunctional prodrug of tegafur for co-delivery of chemotherapeutic agent tegafur and enhanced green fluorescent protein (EGFP) reporter plasmid DNA. Conjugation of tegafur to PEI-CyD via chemical linkage was characterized by ¹H NMR spectrometry and ultraviolet (UV) spectrometry. PEI-CyD-tegafur was able to condense plasmid DNA into complexes of around 150 nm with positive charge at the N/P ratio of 25, in accordance with electron microscopy observation of compact and monodisperse nanoparticles. The results of in vitro experiments showed enhanced cytotoxicity and considerable transfection efficiency in B16F10 cell line. Therefore, PEI-CyD-tegafur may have great potential as a co-delivery system with anti-cancer activity and potential for gene delivery.     

Using sexually explicit material in a therapeutic context

For most of us, sex is a subjective, lived experience that is as unique as our genetic make-up, our upbringing, our thoughts, values, feelings, beliefs and ideas. It is through our erotic interactions, or the absence thereof, that we form aspects of our fluid and mutable erotic paths and identities. Despite the proliferation of sexual imagery throughout our culture, many of us still struggle with what sex means to us, what we do, how we experience it and what that says about who we are as people. Some who struggle with this may seek the services of a psychosexual sex therapist. This paper aims to explain how such services function, why they are necessary and how the use of sexually explicit material, in some psychosexual therapeutic contexts, can help unravel the mixed responses we have to sex and our social conditioning, and enhance our overall relationship to eroticism, pleasure and general well-being.     

Development and implementation of a three-dimensional (3D) printing elective course for health science students

Three-dimensional (3D) printing technology has become more affordable, accessible, and relevant in healthcare, however, the knowledge of transforming medical images to physical prints still requires some level of training. Anatomy educators can play a pivotal role in introducing learners to 3D printing due to the spatial context inherent to learning anatomy. To bridge this knowledge gap and decrease the intimidation associated with learning 3D printing technology, an elective was developed through a collaboration between the Department of Anatomy and the Makers Lab at the University of California, San Francisco. A self-directed digital resource was created for the elective to guide learners through the 3D printing workflow, which begins with a patient's computed tomography digital imaging and communication in medicine (DICOM) file to a physical 3D printed model. In addition to practicing the 3D printing workflow during the elective, a series of guest speakers presented on 3D printing applications they utilize in their clinical practice and/or research laboratories. Student evaluations indicated that their intimidation associated with 3D printing decreased, the clinical and research topics were directly applicable to their intended careers, and they enjoyed the autonomy associated with the elective format. The elective and the associated digital resource provided students with the foundational knowledge of 3D printing, including the ability to extract, edit, manipulate, and 3D print from DICOM files, making 3D printing more accessible. The aim of disseminating this work is to help other anatomy educators adopt this curriculum at their institution.

False negativity to carbohydrate-deficient transferrin and drugs: a clinical case

Introduction:

In this work we report on the possible effect of the medical therapy on CDT concentration in a chronic alcohol abuser, with known medical history (July 2007 – April 2012) and alcohol abuse confirmed by relatives.

Case history:

At the end of 2007, patient displayed the following laboratory results: AST 137 U/L, ALT 120 U/L, GGT 434 U/L, MCV 101 fL and CDT 3.3%. On December 2007, after double coronary artery bypass surgery, he began a pharmacological treatment with amlodipine, perindopril, atorvastatin, isosorbide mononitrate, carvedilol, ticlopidine and pantoprazole. In the next months, until may 2011, the patient resumed alcohol abuse, as confirmed by relatives; however, CDT values were repeatedly found negative (0.8% and 1.1%) despite elevated transaminases and GGT, concurrent elevated ethyl glucuronide concentration (> 50 mg/L) and blood alcohol concentration (> 1 g/L). Alcohol consumption still continued despite increasing disulfiram doses ordered by an Alcohol Rehab Center. On May 2011, the patient was transferred to a private medical center where he currently lives.

Conclusions:

This study suggests the possibility that a medical therapy including different drugs may hamper the identification of chronic alcohol abusers by CDT.
