Two World Wars and Belgium: Missing Births and Birth Sex Ratio Changes.

INTRODUCTION: The sex ratio at birth (male/total births, M/T) is expected to approximate 0.515. M/T is influenced by many factors including stress. Both World Wars have been implicated as influencing birth rates and M/T. This study was carried out to analyse the effects of two World Wars on Belgium vis-à-vis missing births as well as M/T changes. METHODS: Belgian male and female births were available for 1830-2019 and annual population was available from Statista. ARIMA models were used to estimate and project birth losses. The effect of wars was assumed to begin in the years following the commencement of each war and extend to the year after cessation of hostilities i.e., 1915-1919 and 1940-1946 for the First and Second World Wars respectively. RESULTS: This study included 27,346,178 live births for 1830-2019, M/T 0.5124. There was a decreasing trend in births for 1830-2019, significant for 1950-2019. There were dips in births in association with both Wars resulting in over 440,000 missing births, 3.80% of the Belgian population for the First World War and 1.91% for the Second World War. M/T rose non-significantly for the First World War and significantly for the Second World War. DISCUSSION: The declining birth rate and M/T in developed countries is a recognised phenomenon. The missing births in relation to wars are of demographic importance but are often overlooked with emphasis usually on casualties and deaths. M/T may rise in wars, possibly due to increased coital activity as well as other factors.

Assessing the Impact of On-Farm Biosecurity Coaching on Farmer Perception and Farm Biosecurity Status in Belgian Poultry Production.

Veterinary coaching was tested to assess its efficacy in promoting adherence to biosecurity procedures. Poultry farmers (n = 13) in Belgium were profiled using ADKAR®, coached and audited prior to and 6 months after coaching. The ADKAR® (Awareness, Desire, Knowledge, Ability, and Reinforcement) profiling technique identified 5/13 participating farmers with relatively low scores (≤3) for one or more elements that block change (biosecurity compliance in this case). Education was the only demographic variable that influenced knowledge scores. Through the Biocheck.UgentTM methodology, farm biosecurity was assessed and benchmarked to allow for tailored guidance. The farmer, farm veterinarian, and coach defined a farm-specific action plan that covered infrastructure, site access, staff/visitors, purchase policies, transport and depopulation, feed and water supplies, flock management, cleaning and disinfection between flocks, and measures between houses. From a total of 49 proposed actions, 36 were adopted. Purchasing policy had the highest (100%) and cleaning and disinfection had the lowest compliance (38%). Time, cost, and feasibility (e.g., inadequate farm layout) were the main reasons cited for not implementing action points. Overall, biosecurity improved significantly (p = 0.002) from 67.1 ± 5.7% to 70.3 ± 5.7% (mean ± Std. dev). The study, hence, presents convincing proof of how coaching can lead to new solutions not previously considered.

Bismuth-based quadruple therapy versus standard triple therapy for the eradication of Helicobacter pylori in Belgium: a multicentre, non-blinded randomized, prospective study.

Background: Helicobacter pylori (Hp) infection predisposes to malignant and non-malignant diseases warranting eradication. In Belgium, resistance rates for clarithromycin demonstrate regional variations making the use of standard triple therapy (STT) borderline acceptable. According to a recent Belgian survey, STT and bismuth-based quadruple therapy (BQT), are equally frequent prescribed as first line treatment for treatment naïve Hp positive patients. This study aims to evaluate the eradication rates (ER) of BQT versus STT. Methods: Multicentre, non-blinded randomized, prospective study comparing ER in treatment-naïve Hp positive patients. ER were compared by intention to treat (ITT) and per protocol (PP) analysis. Results: Overall 250 patients were included (STT 126, BQT 124). Seventeen patients were lost to follow-up (6,8%). No significant difference in ER between BQT and STT was observed in ITT (73% vs 68%, p= 0,54) neither in PP analysis (81% vs 75%, p= 0,33). Side effects and endoscopic findings were comparable between groups. Post-hoc analysis showed no differences according to gender or site allocation. Conclusion: The numerical advantage of BQT did not translate in a significant improvement of ER when compared with STT. These results question the cost-effectiveness of BQT, while confirming the suboptimal eradication rates on STT. A nationwide monitoring of resistance patterns, maximal investments in treatment adherence as well as a detailed follow-up of the changing treatment landscape are mandatory to continuously optimise Hp ER in Belgium.

Enhancing hospital emergency response based on the experience of COVID-19.

INTRODUCTION: The COVID-19 pandemic required a significant response from global healthcare systems. In Belgium, the crisis began in March 2020, prompting quick action in hospitals. This study assesses the effectiveness of Belgium's hospital emergency plans and compares them with global standards for potential enhancements. METHODOLOGY: An online survey targeting CEOs of 60 Flemish general hospitals evaluated the deployment of hospital emergency coordination cells during the pandemic's first and fourth waves, utilizing various statistical analyses. RESULTS: Findings indicate a high establishment rate of COVID-19 coordination cells before the government's deadline. Despite this readiness, differences in leadership, involvement, and communication strategies were noted among hospitals. There was a notable shift towards hybrid meetings and an evolving role for coordination cells, highlighting the need for a more structured crisis management approach. CONCLUSION: The study concludes that while Flemish hospitals were quick to respond, the lack of a standardized framework suggests the potential for adopting models like the Hospital Incident Command System (HICS) for improved crisis management. Future research should examine the long-term effects of these strategies and the integration of comprehensive emergency management systems in Belgium's healthcare.

New species of Ontocetus (Pinnipedia: Odobenidae) from the Lower Pleistocene of the North Atlantic shows similar feeding adaptation independent to the extant walrus (Odobenus rosmarus).

Ontocetus is one of the most notable extinct odobenines owing to its global distribution in the Northern Hemisphere. Originating in the Late Miocene of the western North Pacific, this lineage quickly spread to the Atlantic Ocean during the Pliocene, with notable occurrences in England, Belgium, The Netherlands, Morocco and the eastern seaboard of the United States. Reassessment of a pair of mandibles from the Lower Pleistocene of Norwich (United Kingdom) and a mandible from the Upper Pliocene of Antwerp (Belgium) that were referred to as Ontocetus emmonsi reveals existences of features of both Ontocetus and Odobenus. The presence of four post-canine teeth, a lower canine larger than the cheek-teeth and a lower incisor confirms the assignment to Ontocetus; simultaneously, characteristics such as a fused and short mandibular symphysis, a well-curved mandibular arch and thin septa between teeth align with traits usually found in Odobenus. Based on a combination of these characters, we describe Ontocetus posti, sp. nov. Its mandibular anatomy suggests, a better adaptation to suction-feeding than what was previously described in the genus suggesting that Ontocetus posti sp. nov. likely occupied a similar ecological niche to the extant walrus Odobenus rosmarus. Originating from the North Pacific Ocean, Ontocetus most likely dispersed via the Central American Seaway. Although initially discovered in the Lower Pliocene deposits of the western North Atlantic, Ontocetus also left its imprint in the North Sea basin and Moroccan Plio-Pleistocene deposits. The closure of the Isthmus of Panama during the Mio-Pliocene boundary significantly impacted the contemporary climate, inducing global cooling. This event constrained Ontocetus posti in the North Sea basin leaving the taxon unable to endure the abrupt climate changes of the Early Pleistocene, ultimately going extinct before the arrival of the extant counterpart, Odobenus rosmarus.

Antimicrobial susceptibility of commensal Neisseria spp. in parents and their children in Belgium: a cross-sectional survey.

BACKGROUND: commensal Neisseria species are part of the oropharyngeal microbiome and play an important role in nitrate reduction and protecting against colonization by pathogenic bacteria. They do, however, also serve as a reservoir of antimicrobial resistance. Little is known about the prevalence of these species in the general population, how this varies by age and how antimicrobial susceptibility varies between species. METHODS: we assessed the prevalence and antimicrobial susceptibility of commensal Neisseria species in the parents (n = 38) and children (n = 50) of 35 families in Belgium. RESULTS: various commensal Neisseria (n = 5) could be isolated from the participants. Most abundant were N. subflava and N. mucosa. Neisseria subflava was detected in 77 of 88 (87.5%) individuals and N. mucosa in 64 of 88 (72.7%). Neisseria mucosa was more prevalent in children [41/50 (82%)] than parents [23/38 (60.5%); P < .05], while N. bacilliformis was more prevalent in parents [7/36 (19.4%)] than children [2/50 (4%); P < .05]. Neisseria bacilliformis had high ceftriaxone minimum inhibitory concentrations (MICs; median MIC 0.5 mg/l; IQR 0.38-0.75). The ceftriaxone MICs of all Neisseria isolates were higher in the parents than in the children. This could be explained by a higher prevalence of N. bacilliformis in the parents. INTERPRETATION: the N. bacilliformis isolates had uniformly high ceftriaxone MICs which warrant further investigation.

Ethical and Epistemological Implications of Conducting Ethnographic Fieldwork as a Researcher-cum-Clinician in Brussels, Belgium.

We draw on ethnographic fieldwork conducted in Brussels (Belgium) on the health care experiences of undocumented migrants. We explore the implications of the double position of the ethnographer, who is both a researcher and a practicing doctor. We describe how the intimate knowledge the ethnographer-cum-clinician holds about the health care system influenced and shaped the data collection, analysis and subsequent policy recommendations. We examine the ethical dilemmas in conducting research from an engaged position about care practices toward vulnerable populations in one's own professional field. We conclude with recommendations on how to challenge and interrupt complexities faced by multi-positioned ethnographers.

Hospitalizations for hip and non-hip osteoporotic fractures in Belgium: nationwide trends between 2010 and 2021.

This study aimed to describe the incidence of hospitalizations for osteoporotic fractures in patients aged 50 years and over in Belgium between 2010 and 2021. A declining trend in crude and age-adjusted hospitalization incidence was observed, however, the absolute number of hospitalisations for osteoporotic fractures increased due to demographic changes. PURPOSE: The secular trends of hospitalizations for hip and other osteoporotic fractures between 2010 and 2021 in patients aged 50 years and over in Belgium are unknown. This study aimed to describe the incidence of hospitalizations for osteoporotic fractures in patients aged 50 years and over in Belgium between 2010 and 2021. METHODS: Population-based, retrospective study based on hospitalization data extracted by the national database NIHDI and demographical data retrieved from the Belgian Federal Bureau for Statistics. Data were combined to determine the crude and age-standardized hospitalization incidence of fractures of the hip, distal femur, pelvis, humerus, wrist, and spine (2010 as the reference year). RESULTS: A total of 445,234 hospitalizations for osteoporotic fractures were reported between 2010 and 2021 (excluding 2015). Hospitalizations increased by 5.8% between 2010 and 2021 (p = 0.013) with a higher increase in men (12.1%; p = 0.001) compared to women (4.1%; p = 0.041). The crude incidence of hospitalizations for all fractures per 100,000 persons per year decreased from 990 to 910 between 2010 and 2021 (p = 0.572). The age-standardized incidence for hospitalizations of any osteoporotic fracture in men declined from 5.30/1,000 to 4.42/1,000 (p = 0.010). In women, a similar decrease was observed (13.84/1,000 to 11.62/1,000; p = 0.003). Both age-standardized hospitalizations for hip and non-hip fractures showed a decrease in both sexes. CONCLUSION: Although a declining trend in the crude incidence per 100,000 and in the age-adjusted incidence of hospitalizations for osteoporotic fractures was observed, the absolute number of hospitalizations for osteoporotic fractures increased due to the demographic change of an ageing population.

Homelessness and housing problems in admitted psychiatric patients in Flanders, Belgium.

Homelessness in psychiatric patients in Flanders, Belgium, has never been investigated. Advocacy groups from patients with lived experience of psychiatric disorders have sounded the alarm on the scarcity of suitable housing options, the strain on psychiatric institutions, and the challenges faced by social service workers. To investigate the extent of the problem a survey on the topic was initiated. A "homelessness-in-mental-health-questionnaire" was designed by experts in the field. The social services of all Flemish psychiatric hospitals and all psychiatric wards in general hospitals were contacted and invited to complete this survey. 24 of 70 contacted services responded. The total number of homeless patients in the inpatient setting on an annual basis are estimated to an average 19.5%. 18% of homeless patients remain longer in admission due to the lack of housing options. 13.7% of homeless psychiatric patients are referred to a community care facility such as an assisted living facility. Social service respondents reported spending an average of 27.4% of their work time on housing issues. The main focus points according to the respondents are the lack of priority measures for homeless psychiatric patients, psychiatric problems as a barrier to housing options and the shortage of adapted housing capacity. The conclusion of this study is the need for comprehensive policy interventions to ensure an adequate supply of suitable social housing for psychiatric patients, accessible mental health care, alternative housing options and crisis accommodation facilities. We propose a 10-point action plan on housing for psychiatric patients for policymakers and politicians.

Congenital Myasthenic Syndromes in Belgium: Genetic and Clinical Characterization of Pediatric and Adult Patients.

BACKGROUND: Congenital myasthenic syndromes (CMS) are a group of genetic disorders characterized by impaired neuromuscular transmission. CMS typically present at a young age with fatigable muscle weakness, often with an abnormal response after repetitive nerve stimulation (RNS). Pharmacologic treatment can improve symptoms, depending on the underlying defect. Prevalence is likely underestimated. This study reports on patients with CMS followed in Belgium in 2022. METHODS: Data were gathered retrospectively from the medical charts. Only likely pathogenic and pathogenic variants were included in the analysis. RESULTS: We identified 37 patients, resulting in an estimated prevalence of 3.19 per 1,000,000. The patients harbored pathogenic variants in CHRNE, RAPSN, DOK7, PREPL, CHRNB1, CHRNG, COLQ, MUSK, CHRND, GFPT1, and GMPPB. CHRNE was the most commonly affected gene. Most patients showed disease onset at birth, during infancy, or during childhood. Symptom onset was at adult age in seven patients, caused by variants in CHRNE, DOK7, MUSK, CHRND, and GMPPB. Severity and distribution of weakness varied, as did the presence of respiratory involvement, feeding problems, and extraneuromuscular manifestations. RNS was performed in 23 patients of whom 18 demonstrated a pathologic decrement. Most treatment responses were predictable based on the genotype. CONCLUSIONS: This is the first pooled characterization of patients with CMS in Belgium. We broaden the phenotypical spectrum of pathogenic variants in CHRNE with adult-onset CMS. Systematically documenting larger cohorts of patients with CMS can aid in better clinical characterization and earlier recognition of this rare disease. We emphasize the importance of establishing a molecular genetic diagnosis to tailor treatment choices.

Analyzing laboratory test utilization trends in belgian primary care: a decade of insights with international perspectives.

BACKGROUND: Clinical laboratory testing, essential for medical diagnostics, represents a significant part of healthcare activity, influencing around 70% of critical clinical decisions. The automation of laboratory equipment has expanded test menus and increased efficiency to meet the growing demands for clinical testing. However, concerns about misutilization remain prevalent. In Belgium, primary care has seen a dramatic increase in lab test usage, but recent utilization data is lacking. METHODS: We conducted a comprehensive retrospective analysis of laboratory test utilization trends within the primary care settings of Belgium over a ten-year period, spanning from 2012 to 2021, incorporating a vast dataset of 189 million test records for almost 1.5 million persons. This was the first study to integrate the metadata from both the INTEGO & THIN databases, which are derived from the two major electronic medical record (EMR) systems used in primary care in Belgium, providing a comprehensive national perspective. This research provides crucial insights into patient-level patterns, test-level utilization, and offers international perspectives through comparative analysis. RESULTS: We found a subtle annual increase in the average number of laboratory tests per patient (ranging from approximately 0.5-1%), indicative of a deceleration in growth in laboratory test ordering when compared to previous decades. We also witnessed stability and consistency of the most frequently ordered laboratory tests across diverse patient populations and healthcare contexts over the years. CONCLUSIONS: These findings emphasize the need for continued efforts to optimize test utilization, focusing not only on tackling overutilization but on enhancing the diagnostic relevance of tests ordered. The frequently ordered tests should be prioritized in these initiatives to ensure their continued effectiveness in patient care. By consolidating extensive datasets, employing rigorous statistical analysis, and incorporating international perspectives, this study provides a solid foundation for evidence-based strategies aimed at refining laboratory test utilization practices. These strategies can potentially improve the quality of healthcare delivery while simultaneously addressing cost-effectiveness concerns in healthcare.

Primary Healthcare Providers' Views on Periodic COVID-19 Booster Vaccination for Themselves and Their Patients: A 2023 Nationwide Survey in Belgium.

New COVID-19 strains and waning vaccine effectiveness prompted initiatives for booster vaccination. In Belgium, healthcare providers (HCPs) received a second booster in July 2022, with eligible individuals receiving a third in autumn. Primary HCPs (PHCPs) play a crucial role in healthcare organization and patient communication. This study, conducted in February-March 2023, surveyed 1900 Belgian PHCPs to assess their views on periodic COVID-19 boosters for themselves and their patients. The survey included questions on sociodemographic information, willingness to receive periodic COVID-19 boosters, reasons for acceptance or refusal, confidence in vaccine safety and efficacy, and views on booster recommendations. Overall, 86% of participants were willing to receive periodic COVID-19 boosters, motivated by self-protection, patient well-being, and the uninterrupted delivery of healthcare services. Factors influencing booster refusal included not being a general practitioner (GP) or GP trainee, working in Wallonia or Brussels, and lacking vaccine confidence. Although 243 participants would not take boosters periodically, only 74 would not recommend it. Regarding administration, 59% supported pharmacist involvement in COVID-19 vaccination. Further qualitative analysis of 290 PHCPs' responses revealed varying recommendations, including specific roles like nurses, organizational structures, and collaborative approaches. This study highlights the need to address vaccine confidence, regional disparities, and PHCP roles in booster implementation.

Experiences and observations from a care point for displaced Ukrainians: a community case study in Antwerp, Belgium.

Background: A total of 7,307 Ukrainian refugees moved to Antwerp, Belgium, during the study period (01 April 2022 to 31 December 2022). The city's administration set up three care centers where these people were introduced to the Belgian primary care system, a medical file was created, and acute/preventive/chronic care was delivered. This community case study analyzes the organization and contents of care and reflects upon its meaning for the mainstream healthcare system. Methods: This is an observational study using routine electronic medical record data to measure the uptake of care. For a sample of 200 subjects, a retrospective chart review was conducted. Participants: All refugees with a medical file at one of the three participating care centers were included. Main outcomes: For the observational study, 2,261 patients were reached (30% of the potential users), and 6,450 contacts were studied. The nurses (including midwives) conducted 4,929 out of 6,450 (76%) of all consultations, while the general practitioners (GPs) conducted 1,521 out of 6,450 (24%). Of the nurse consultations, 955 (19%) were followed by another nurse consultation and 866 (18%) by a GP consultation. In the structured case reviews, most contacts were concerned with acute problems (609 out of 1,074, 57%). The most prevalent reasons for encounters and diagnoses were typical primary care issues. The nurses were able to manage half of the cases independently (327, 55%), referred 37% (217) of cases to the GP, and consulted a GP (live, by telephone, or a dedicated app) for 8% (48) of cases. GPs mostly prescribed drugs, referred to a medical specialist, and advised over-the-counter drugs, while nurses more often advised over-the-counter drugs (mostly paracetamol, nose sprays, and anti-inflammatory drugs), provided non-medical advice, or ordered laboratory tests. Discussion: The medical care points delivered mostly typical acute primary care in this first phase, with a key role for nurses. The care points did not sufficiently take up chronic diseases and mental health problems. These results will inform policymakers on the use of primary care centers for newly arriving patients in times of a large influx. A nurse-first model seems feasible and efficient, but evaluation of safety and quality of care is needed. Once the acute phase of this crisis fades away, questions about the comprehensiveness, continuity, and integration of care for migrants remain relevant.

Comparative trends of brucellosis serological testing and confirmed brucellosis cases suggest inappropriate prescription habits.

BACKGROUND: Brucellosis is a zoonosis endemic to specific geographical regions. In first line laboratories, diagnosis is made by blood culture or Rose Bengal (RB) serology. METHODS: We compare brucellosis testing between 2012-2021 at two university hospitals in Brussels, Belgium with concomitant national confirmed cases and institutional cases. RESULTS: RB testing increased from 30 to 211 tests/year between 2012-2021. A total of fifty-two national brucellosis cases were notified during the study period, of which fifteen cases in Brussels. No trend was noted nationally or regionally. Epidemiological data indicated travel to endemic regions, confirmed by strain testing. Institutional cases all showed symptomatic presentations with positive travel histories. CONCLUSIONS: Serologic testing inappropriately increases yearly, while annual imported brucellosis cases remain rare, and have positive travel histories and are symptomatic. We therefore support current recommendations of limiting RB testing to symptomatic patients at risk of exposure, meaning predominantly positive recent travel history.

Brief communication: temporal trends of chronic diseases medications prescriptions among HIV-infected patients in Belgium: a 4-year population-based study using pharmacy claims data.

The Objective of this study was to examine change over time of prevalence of chronic diseases medications (CDM) prescriptions among People living with HIV (PLWH) in Belgium, using Pharmanet database from 2018 to 2021. We identified 13,570, 14,175, 14,588 and 14,813 PLWH in 2018, 2019, 2020 and 2021, respectively. Prescriptions of cardiovascular diseases (CVD) medications (31.7-37.2%) and antidiabetics (7.4-9.0%), increased significantly (p for trend < 0.001 for all), while the prescription of neurological and mental disorders medications (18.0-19.3%) remained stable (p for trend = 0.11) and the prescription of chronic respiratory diseases (CRD) medications decreased from 12.2 to 10.6% (p for trend < 0.001), between 2018 and 2021. It is imperative to ensure that these medications are used appropriately.

Geospatial patterns of excess mortality in Belgium: Insights from the first year of the COVID-19 pandemic.

OBJECTIVES: Belgium experienced multiple COVID-19 waves that hit various groups in the population, which changed the mortality pattern compared to periods before the pandemic. In this study, we investigated the geographical excess mortality trend in Belgium during the first year of the COVID-19 pandemic. METHODS: We retrieved the number of deaths and population data in 2020 based on gender, age, and municipality of residence, and we made a comparison with the mortality data in 2017-2019 using a spatially discrete model. RESULTS: Excess mortality was significantly associated with age, gender, and COVID-19 incidence, with larger effects in the second half of 2020. Most municipalities had higher risks of mortality with a number of exceptions in the northeastern part of Belgium. Some discrepancies in excess mortality were observed between the north and south regions. CONCLUSIONS: This study offers useful insight into excess mortality and will aid local and regional authorities in monitoring mortality trends.

Assessing the Prevalence and Dynamics of Emerging Campylobacterales in Human Stool Samples in Brussels by Filtration Culture.

Thermophilic C. jejuni/coli is reported to be the first bacterial cause of gastroenteritis worldwide and the most common zoonosis in Europe. Although non-jejuni/coli Campylobacter sp. are increasingly suspected to be responsible for diarrhoea or to be involved in inflammatory bowel disease, they remain poorly isolated due to their fastidious and non-thermophilic nature. Additionally, they are not targeted by commercial syndromic PCR assays. In this study, we present routine diagnostic results over 6 years (2017-2019 and 2021-2023) of Campylobacter sp. and related species, obtained by optimised culture from 51,065 stools by both 0.65 µm pore filtration on antibiotic-free agar, incubated in an H2-enriched atmosphere at 37 °C (also known as the Cape Town protocol), and the use of selective inhibitory Butzler medium incubated at 42 °C. This allowed the isolation of 16 Campylobacter species, 2 Aliarcobacter species, and 2 Helicobacter species, providing a completely different view of the epidemiology of Campylobacterales, in which C. jejuni/coli represents only 30.0% of all isolates, while C. concisus represents 44.4%. C. ureolyticus, representing only 5.5% of all Campylobacterales pre-COVID-19, represented 20.6% of all strains post-COVID-19 (218% increase; p < 0.05). At the same time, the proportions of C. jejuni, C. coli, and C. concisus decreased by 37, 53, and 28%, respectively (p < 0.05).

[The cultural intermediary model, a source of alternative views on nursing activity in palliative care]. / Le modèle d'intermédiaire culturel, source d'autres regards sur l'activité infirmière en soins palliatifs.

With the aim of describing the activities of nurses in mobile home palliative care teams in the Brussels Region, the study Nursing practices in palliative care in Brussels outpatient mobile teams took the cultural intermediary model as its theoretical framework. This model is based on in-depth research into the history of the nursing discipline. This article provides an overview of this European conceptual model, its integration into a descriptive study, and highlights some of its contributions.

Clinical audit of quality of care among patients with viral hepatitis in primary care in a low endemic region.

BACKGROUND: The current hepatitis B (HBV) and hepatitis C virus (HCV) screening practices may fail to detect many infected patients who could benefit from new therapeutic agents to limit progression to cirrhosis and hepatocellular carcinoma. OBJECTIVES: This study assessed the test positivity rate and cascade of care of viral hepatitis patients in primary care in a low endemic region as well as the testing policy of abnormal alanine aminotransferase (ALT) level. METHODS: This is a retrospective clinical audit among primary health care practices in Flanders, Belgium, assessing patients with an active medical file between 2019 and 2021. RESULTS: A total of 84/89 (94.4%) primary health care practices participated representing 621,573 patients of which 1069 patients (0.17%) were registered as having viral hepatitis, not further specified. Detailed information was available from 38 practices representing 243,723/621,573 (39.2%) patients of which 169 (0.07%) were HBsAg positive and 99 (0.04%) anti-HCV positive. A total of 96/134(71.6%) chronic HBV-infected and 31/77(40.3%) chronic HCV-infected patients were referred to a hepatologist. A total of 30,573/621,573(4.9%) patients had an abnormal ALT level, and by at random selection, more detailed information was obtained on 211 patients. Information on high-risk groups was missing in up to 60%. In patients with abnormal ALT level, HBsAg and anti-HCV testing were conducted in 37/211(17.5%) and 25/211(11.8%), respectively. CONCLUSION: In a low endemic region, the testing rate and cascade of care of HBV and HCV-infected patients can be improved in primary care, especially in high-risk groups and patients with abnormal ALT levels.

Infections with the hepatitis B virus (HBV) and hepatitis C virus (HCV) are a leading cause of death worldwide. Over the last decade, several new therapeutic agents have been developed and can now prevent hepatitis-related deaths. Awareness and increasing testing rates for viral hepatitis in primary care could therefore contribute to control these diseases. The findings of our clinical audit among primary health care practices in Flanders, Belgium demonstrate that screening for HBV and HCV infection can be improved in primary health care in a low endemic region, especially in high-risk groups (e.g. migrants who originate from an endemic country) and patients with abnormal ALT level. The observed suboptimal testing rate in primary health care may be due to a lack of information on risk groups. Future research should focus on interventions to enhance testing, linkage to care, and treatment initiation for HBV and HCV infection among well-defined risk groups in primary health care.

[Protontherapy : principles, advantages, limitations, indications, perspectives...and some Belgian peculiarities]. / La protonthérapie : principes, avantages, limitations, indications, perspectives...et quelques histoires belges.

Most radiotherapy treatments are nowadays delivered with linear accelerators producing photons. This robust radiation technique improved outstandingly during the last three decades, allowing treatments for most tumoural indications with an exquisite accuracy, a formidable effectiveness, a low toxicity, and a very low cost for the society. Therefore, the reasons for using and developing the more expensive hadron therapy and more particularly proton therapy may seem futile. In the current article targeting the general practitioners readership, we look at the principles of this innovative technique, its inherent advantages and limitations, the current and future indications, the challenges and perspectives for the future. We conclude with an overview of the Belgian landscape in terms of installation, operation, access and reimbursement procedures.

L'essentiel des traitements de radiothérapie sont délivrés à l'aide d'accélérateurs linéaires produisant des photons. La technique est robuste et a connu une évolution fulgurante ces trois dernières décennies, apportant une efficacité redoutable et une extrême précision dans de nombreuses indications tumorales, avec les avantages d'un risque de toxicité réduit et d'un coût sociétal extrêmement faible. Dès lors, quel intérêt y aurait-il à utiliser et développer des traitements de radiothérapie par hadrons, et plus particulièrement par protons, sachant que les coûts d'installation et de production sont, au bas mot, décuplés par rapport aux photons ? Dans cet article destiné en première intention aux praticiens de santé généralistes, nous abordons les principes de fonctionnement, les avantages et limitations inhérents à la technique, les indications actuelles et celles qui se profilent, les défis et perspectives à venir. Nous terminons, enfin, par un tour d'horizon du paysage belge en termes d'installation, de fonctionnement, d'accès et de modalités de remboursement.
