Pharmacological Studies in Hospitalized COVID-19 Patients in Belgium: We Could Do Better

Belgium has actively participated in clinical research on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) since the beginning of the pandemic to help identify effective and safe treatments for COVID-19. The objective of this review is to provide a picture of the clinical studies carried out in hospitalized patients with COVID-19 in Belgium. We collected data on all randomized, interventional trials in patients with COVID-19 that were registered on two recognized clinical trial registers, started enrollment before 31 December 2021, and included at least one patient in a Belgian center. Data were collected concerning the therapies investigated and the nature of the trials performed. Thirty-three hospitals (32% of all Belgian hospitals) participated in at least one of 28 trials (13 sponsored by the industry and 15 by academic centers) on therapeutics for COVID-19 in hospitalized patients: 7 (25%) evaluated antivirals, 17 (61%) immunomodulators, 2 (7%) anti-coagulants, and 1 (3%) nitric oxide to improve respiratory function. Nineteen (68%) were phase II trials. Only three (11%) of the trials were international platform trials. Despite numerous trials, less than 3% of all Belgian patients hospitalized with COVID-19 participated in a clinical trial on therapeutics. As in many other countries, more efforts could have been made to avoid running small, under-powered, mono- or bicenter trials, to create better collaboration between the different Belgian hospitals, and to participate in more international clinical trials, and more specifically in adaptive, platform trials.     

Short-term perioperative outcomes after robot-assisted and laparoscopic distal pancreatectomy

Robotic surgery offers potential technical advantages that may facilitate pancreatic resection. The aim of this study was to evaluate the learning curve and short-term perioperative outcomes in patients who underwent laparoscopic and robot-assisted distal pancreatectomy. All perioperative variables were evaluated and compared retrospectively between laparoscopic (LDP) (n = 23) and robot-assisted (RDP) (n = 11) distal pancreatectomy. The mean total operative time was shorter in LDP (194 vs. 225 min; p = 0.017). All other perioperative criteria were similar between LDP and RDP patients (blood loss, transfusion rate, conversion, pancreatic fistula, postoperative morbidity, and duration of hospitalization). Non-adjusted CUSUM curve for composite events including operative time, conversion, postoperative morbidity and reoperation rates showed that the RDP learning curve corresponded to the first seven consecutive patients. During early experience, RDP was associated with longer operative time but similar short-term perioperative outcomes compared to conventional distal pancreatectomy.     

Effects of an adapted leisure education program as a means of support for caregivers of people with dementia

The loss of autonomy associated with dementia affects the people with dementia themselves as well as their caregivers who are often left feeling powerless and incompetent in their caregiving role. Most of the programs developed to support caregivers focus on burden and do not consider the positive aspects of caregiving. Leisure represents a way to enhance the presence of positive aspects in the caring experience. Moreover, leisure might contribute to the maintenance of satisfactory relationships between the caregivers and the person with dementia. An adapted leisure education program was developed as a means of support to caregiver involvement. This study (n = 49) aims to evaluate the impact of this program on caregivers’ well-being, self-efficacy towards adapted leisure, and quality of the relationship with the care receiver. Mixed methods were used. Pretest-posttest with a follow-up design made up the quantitative part. In addition, open-end interviews (n = 10) were conducted. The quantitative results showed few impacts of the program on caregivers. However, the qualitative analysis revealed that the intervention had positive impacts for the caregivers, care receivers and other family members. This study introduces caregiver support in a new, positive perspective by focusing on the positive aspects of caregiving rather than the burden.     

Sphincter pharyngoplasty as a treatment of velopharyngeal incompetence in young people: a prospective evaluation of effects on sleep structure and sleep respiratory disturbances

BACKGROUND: Sphincter pharyngoplasty (SP) appears to be the more "physiologic" surgical technique to treat velopharyngeal incompetence (VPI). This procedure creates a dynamic sphincter of variable diameter and keeps the flexibility of the soft palate. SP also induces velopharyngeal size reduction, mainly in the transverse diameter, which may cause upper airway (UA) occlusions during sleep. AIM: To prospectively evaluate the effects of SP by a modified Orticochea procedure on sleep structure and sleep respiratory disturbances. METHODS: Polysomnographic studies before and after surgery in 17 consecutive patients treated by a modified Orticochea procedure SP for VPI. RESULTS: For the whole group, SP did not induce significant impairment of apnea-hypopnea index or nocturnal oxygen saturation. Slow-wave sleep (SWS) was significantly reduced after surgery (25 +/- 9% of total sleep time [TST] vs 28 +/- 9% of TST before SP [p = 0.04]). Following surgery, there was a trend for an increase in the microarousal index) (p = 0.09) and more specifically in respiratory-related microarousals. CONCLUSION: SP, although creating a clinically obvious reduction of velopharyngeal diameter, generally did not lead to the occurrence of an obstructive sleep apnea syndrome. However, we found a significant reduction of SWS quantity and a trend toward an increase in the number of cortical microarousals. These findings suggest that the reduction of UA diameter associated with the surgical technique leads to increases in respiratory effort sufficient to induce sleep fragmentation and SWS reduction, even in the absence of apneas or hypopneas.
