Clinical and molecular epidemiological features of critically ill patients with invasive group A Streptococcus infections: a Belgian multicenter case-series.

Background: Recent alerts have highlighted an increase in group A streptococcal (GAS) infections since 2022 in Europe and the United States. Streptococcus pyogenes can cause limited skin or mucosal disease, but can also present as severe invasive disease necessitating critical care. We performed a multicenter retrospective study of patients with GAS infections recently admitted to Belgian intensive care units (ICUs) since January 2022.

A spinal cord neuroprosthesis for locomotor deficits due to Parkinson's disease.

People with late-stage Parkinson's disease (PD) often suffer from debilitating locomotor deficits that are resistant to currently available therapies. To alleviate these deficits, we developed a neuroprosthesis operating in closed loop that targets the dorsal root entry zones innervating lumbosacral segments to reproduce the natural spatiotemporal activation of the lumbosacral spinal cord during walking. We first developed this neuroprosthesis in a non-human primate model that replicates locomotor deficits due to PD.

Principles of gait encoding in the subthalamic nucleus of people with Parkinson's disease.

Disruption of subthalamic nucleus dynamics in Parkinson's disease leads to impairments during walking. Here, we aimed to uncover the principles through which the subthalamic nucleus encodes functional and dysfunctional walking in people with Parkinson's disease. We conceived a neurorobotic platform embedding an isokinetic dynamometric chair that allowed us to deconstruct key components of walking under well-controlled conditions.

Neuroprosthetic baroreflex controls haemodynamics after spinal cord injury.

Spinal cord injury (SCI) induces haemodynamic instability that threatens survival, impairs neurological recovery, increases the risk of cardiovascular disease, and reduces quality of life. Haemodynamic instability in this context is due to the interruption of supraspinal efferent commands to sympathetic circuits located in the spinal cord, which prevents the natural baroreflex from controlling these circuits to adjust peripheral vascular resistance. Epidural electrical stimulation (EES) of the spinal cord has been shown to compensate for interrupted supraspinal commands to motor circuits below the injury, and restored walking after paralysis.

Using social robot PLEO to enhance the well-being of hospitalised children.

Hospitalisation is stressful for children. Play material is often offered for distraction and comfort. We explored how contact with social robot PLEO could positively affect a child's well-being.

Social robots to support children's well-being under medical treatment: A systematic state-of-the-art review.

Hospitalization is a stressful experience for children. Socially assistive robots (SARs), designed to interact with humans, might be a means to mitigate a child's stress and support its well-being. A systematic state-of-the-art review was performed to inventorize the use of SARs in hospital to support children's well-being and what the effects are.

Recurrent computations for visual pattern completion.

Making inferences from partial information constitutes a critical aspect of cognition. During visual perception, pattern completion enables recognition of poorly visible or occluded objects. We combined psychophysics, physiology, and computational models to test the hypothesis that pattern completion is implemented by recurrent computations and present three pieces of evidence that are consistent with this hypothesis.

[Practical approach of lymphomas: major role of general practitioner who has to face all these emerging drugs].

Malignant lymphoma and other lymphoproliferative disorders represent a group of malignant hemopathies where immunotherapy has allowed spectacular progresses over the last ten years. The recent W.H.

Plasma circulating tumor DNA as an alternative to metastatic biopsies for mutational analysis in breast cancer.

Background: Molecular screening programs use next-generation sequencing (NGS) of cancer gene panels to analyze metastatic biopsies. We interrogated whether plasma could be used as an alternative to metastatic biopsies.

Patients And Methods: The Ion AmpliSeq™ Cancer Hotspot Panel v2 (Ion Torrent), covering 2800 COSMIC mutations from 50 cancer genes was used to analyze 69 tumor (primary/metastases) and 31 plasma samples from 17 metastatic breast cancer patients.

[Non Hodgkin's lymphomas: a major breakthrough with immunotherapy].

Non hodgkin's lymphomas are a group of haematological malignancies in which spectacular progress has been made over the last ten years thanks to immunotherapy. Furthermore, the new WHO classification, based upon tumour immunology, the degree of tumour differentiation and cytogenetic abnormalities, has finally improved identification of each lymphoma and has enabled comparison of homogeneous populations between different clinical studies. The increase in the incidence of non hodgkin's lymphoma is related to the aging of the population and to other factors that are yet to be elucidated--a real challenge for the future.

How should we treat mucinous appendiceal neoplasm? By laparoscopy or laparotomy? A case report.

Appendicular mucocele (AM) usually denotes a dilatation of the appendiceal lumen as a result of mucus accumulation that may be related to various neoplastic and non-neoplastic processes. Most of them are discovered incidentally. Treatment consists in complete resection avoiding rupture of the cyst in the peritoneal cavity.

Locating sex-specific evidence on clinical questions in MEDLINE: a search filter for use on OvidSP.

Background: Many recently published clinical studies report sex-specific data. This information may help to improve clinical decision-making for both sexes, but it is not easily accessible in MEDLINE. The aim of this project was to develop and validate a search filter that would facilitate the retrieval of studies reporting high quality sex-specific data on clinical questions.

Incorporating a gender perspective into the development of clinical guidelines: a training course for guideline developers.

Background: Dutch guideline-developing organizations do not focus systematically on differences between men and women when developing guidelines, even though there is increasing evidence that being male or female may have an effect on health and health outcomes. In collaboration with two prominent Dutch guideline-developing organizations, we designed a training course to encourage systematic attention to sex differences in guideline development procedures.

Methods: The course is targeted towards guideline developers.

Attention to sex-related factors in the development of clinical practice guidelines.

Background: Clinical practice guidelines describe optimal strategies for disease prevention, diagnosis, or treatment. Increasing evidence indicates that sex-related factors may have an impact on these strategies. We examined the way in which two Dutch guideline organizations address evidence on sex factors in their guideline development methodologies.

Gender equality in the work of local research ethics committees in Europe: a study of practice in five countries.

Background: Funding organisations and research ethics committees (RECs) should play a part in strengthening attention to gender equality in clinical research. In the research policy of European Union (EU), funding measures have been taken to realise this, but such measures are lacking in the EU policy regarding RECs.

Objective: To explore how RECs in Austria, Germany, Ireland, The Netherlands and Sweden deal with gender equality issues by asking two questions: (1) Do existing procedures promote representation of women and gender expertise in the committee? (2) How are sex and gender issues dealt with in protocol evaluation?

Methods: Two RECs were selected from each country.

Searching bibliographic databases for literature on chronic disease and work participation.

Background: The work participation of people with chronic diseases is a growing concern within the field of occupational medicine. Information on this topic is dispersed across a variety of data sources, making it difficult for health professionals to find relevant studies for literature reviews and guidelines.

Aim: The goal of this project was to identify bibliographic databases and search terms that could be most useful for retrieving relevant studies on this topic.

Prolonged schedule of temozolomide (Temodal) plus liposomal doxorubicin (Caelyx) in advanced solid cancers.

Temozolomide (Temodal) is an oral imidazotetrazine. Increased temozolomide exposure and subsequent depletion of O-alkylguanine alkyltransferase may improve the activity of temozolomide. The rationale for investigating temozolomide plus Caelyx is based on their antitumor activity, their formulation and no significant overlapping toxicities.

Treatment of Parkinson's disease with pergolide and relation to restrictive valvular heart disease.

Background: Restrictive valvular heart disease has been reported in patients with Parkinson's disease treated with pergolide. However, few data are available on frequency, severity, dose dependency, and reversibility of pergolide-induced disease, nor on the pulmonary pressures of these patients. We aimed to clarify these characteristics in a large group of patients.

Ultrasonic low-energy treatment: a novel approach to induce apoptosis in human leukemic cells.

Objective: We evaluated the cytotoxic effect of ultrasonic irradiation at low energy on the viability of normal and leukemic cells and the potential mechanisms of action inducing this cytotoxicity.

Materials And Methods: Human leukemia cell lines (K562, HL-60, KG1a, and Nalm-6), primary leukemic cells, and normal mononuclear cells are treated by ultrasound at a frequency of 1.8 MHz during various exposure times (acoustical power of 7 mW/mL) and immediately tested for cell viability by the trypan blue exclusion assay.

Postmenopausal hormone therapy: less favourable risk-benefit ratios in healthy Dutch women.

Objectives: To estimate the health effects of postmenopausal hormone therapy used for 10 or 20 years in a population of intermediate cardiovascular risk.

Design: Using existing estimates of the effect of hormone therapy on rates of myocardial infarction, hip fracture and breast cancer, a proportional multistage life table was generated to calculate the effects of use for 10 and 20 years in a synthetic cohort of Dutch women aged 55 with an average and a high-risk profile for cardiovascular disease.

Results: A woman of the general population who starts hormone therapy at age 55 for 10 years can prolong her life by 1 month and may postpone the occurrence of first incidence of one of the diseases under consideration by 2.

The epidemiology of gallbladder cancer: lifestyle related risk factors and limited surgical possibilities for prevention.

Cancer of the gallbladder is a rare cancer with a poor prognosis. Most patients die within 1 year. The incidence shows large geographic variation and is higher in females and in certain ethnic groups.

Sex differences in illness beliefs and illness behavior in patients with suspected coronary artery disease.

The aim of this study was to explore sex differences in illness beliefs and behavior in patients with suspected coronary artery disease (CAD). Twenty-eight patients, 16 women and 12 men, were interviewed. The results show that both men and women think of CAD as a 'men's disease' and have equal knowledge of CAD risk factors.

Epidemiologic aspects of gallbladder cancer: a case-control study of the SEARCH Program of the International Agency for Research on Cancer.

Background: There are few previous epidemiologic studies of gallbladder cancer, a rare but nearly always lethal gastrointestinal cancer with a demonstrated greater frequency in adult women and older subjects of both sexes, and also in the members of populations throughout central and eastern Europe and certain racial groups such as native American Indians. Unfortunately, the prospects for the prevention of this form of cancer are poor.

Purpose: Our purpose in conducting this study was to investigate possible new risk factors for gallbladder cancer and to strengthen our understanding of established causal agents that may be involved in this disease.
