Abstract
Vibrotactile feedback training may be used as a complementary strategy to reduce time in demanding postures in manual handling. This study evaluated the short- and medium-term effects of concurrent posture-correction vibrotactile feedback training on trunk inclination exposure in real manual sorting work. Fifteen warehouse workers completed the training and the follow-up sessions. Trunk inclination angles were recorded using the ambulatory Smart Workwear System. Questionnaires were used for assessing system usability, perceived physical exertion, and work ability. The results showed reduced time in trunk inclination >30°, >45°, and >60°, and reductions in the 90th, 95th, and 99th percentile trunk inclination angles, when receiving feedback and immediately after feedback withdrawal. No significant reduction was retained after one and three weeks. The wearer's comfort was scored high, and the feedback did not increase the perceived cognitive demands. No significant effects attributed to changed trunk inclination exposure were observed for perceived physical exertion or work ability. The training program has the potential of contributing to reduced trunk inclination exposure in the short term. Future studies are needed to evaluate if improvements in the feedback training can transfer the short-term results to retained median- and long-term effects.Practitioner summary: A two-day training program with concurrent posture-correction vibrotactile feedback can contribute to reduced exposure of trunk inclination in real manual sorting work in the short term. More research is needed on how to design the feedback training programs in order to be effective in the long term.

Abstract
BACKGROUND Residents of nursing homes (NHs) are at high risk of coronavirus disease 2019 (COVID-19)-related disease and death and may respond poorly to vaccination because of old age and frequent comorbid conditions. METHODS Seventy-eight residents and 106 staff members, naive to infection or previously infected with severe acute respiratory syndrome coronavirus (SARS-CoV-2), were recruited in NHs in Belgium before immunization with 2 doses of 30 µg BNT162b2 messenger RNA (mRNA) vaccine at days 0 and 21. Binding antibodies (Abs) to SARS-CoV-2 receptor-binding domain (RBD), spike domains S1 and S2, RBD Ab avidity, and neutralizing Abs against SARS-CoV-2 wild type and B.1.351 were assessed at days 0, 21, 28, and 49. RESULTS SARS-CoV-2-naive residents had lower Ab responses to BNT162b2 mRNA vaccination than naive staff. These poor responses involved lower levels of immunoglobulin (Ig) G to all spike domains, lower avidity of RBD IgG, and lower levels of Abs neutralizing the vaccine strain. No naive residents had detectable neutralizing Abs to the B.1.351 variant. In contrast, SARS-CoV-2-infected residents had high responses to mRNA vaccination, with Ab levels comparable to those in infected staff. Cluster analysis revealed that poor vaccine responders included not only naive residents but also naive staff, emphasizing the heterogeneity of responses to mRNA vaccination in the general population. CONCLUSIONS The poor Ab responses to mRNA vaccination observed in infection-naive NH residents and in some naive staff members suggest suboptimal protection against breakthrough infection, especially with variants of concern. These data support the administration of a third dose of mRNA vaccine to further improve protection of NH residents against COVID-19.

Abstract
Fractional dosing of COVID-19 vaccines could accelerate vaccination rates in low-income countries. Dose-finding studies of the mRNA vaccine BNT162b2 (Pfizer-BioNTech) suggest that a fractional dose induces comparable antibody responses to the full dose in people <55 years. Here, we report the safety and immunogenicity of a fractional dose regimen of the BNT162b2 vaccine. REDU-VAC is a participant-blinded, randomised, phase 4, non-inferiority study. Adults 18-55 years old, either previously infected or infection naïve, were randomly assigned to receive 20μg/20μg (fractional dose) or 30μg/30μg (full dose) of BNT162b2. The primary endpoint was the geometric mean ratio (GMR) of SARS-CoV-2 anti-RBD IgG titres at 28 days post second dose between the reduced and full dose regimens. The reduced dose was considered non-inferior to the full dose if the lower limit of the two-sided 95% CI of the GMR was >0.67. Primary analysis was done on the per-protocol population, including infection naïve participants only. 145 participants were enrolled and randomized, were mostly female (69.5%), of European origin (95%), with a mean age of 40.4 years (SD 7.9). At 28 days post second dose, the geometric mean titre (GMT) of anti-RBD IgG of the reduced dose regimen (1,705 BAU/mL) was not non-inferior to the full dose regimen (2,387 BAU/mL), with a GMR of 0.714 (two-sided 95% CI 0.540-0.944). No serious adverse events occurred. While non-inferiority of the reduced dose regimen was not demonstrated, the anti-RBD IgG titre was only moderately lower than that of the full dose regimen and, importantly, still markedly higher than the reported antibody response to the licensed adenoviral vector vaccines. These data suggest that reduced doses of the BNT162b2 mRNA vaccine may offer additional benefit as compared to the vaccines currently in use in most low and middle-income countries, warranting larger immunogenicity and effectiveness trials. Trial Registration: The trial is registered at ClinicalTrials.gov (NCT04852861).

Abstract
Background The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has presented itself as one of the most important health concerns of the 2020’s, and hit the geriatric population the hardest. The presence of co-morbidities and immune ageing in the elderly lead to an increased susceptibility to COVID-19, as is the case for other influenza-like illnesses (ILI) or acute respiratory tract infections (ARI). However, little is known, about the impact of a previous or current infection on the other in terms of susceptibility, immune response, and clinical course. The aim of the “Prior Infection with SARS-COV-2” (PICOV) study is to compare the time to occurrence of an ILI or ARI between participants with a confirmed past SARS-CoV-2 infection (previously infected) and those without a confirmed past infection (naïve) in residents and staff members of nursing homes. This paper describes the study design and population characteristics at baseline. Methods In 26 Belgian nursing homes, all eligible residents and staff members were invited to participate, resulting in 1,226 participants. They were classified as naïve or previously infected based on the presence of detectable SARS-CoV-2 antibodies and/or a positive RT-qPCR result before participation in the study. Symptoms from a prior SARS-CoV-2 infection between March and August 2020 were compared between previously infected residents and staff members. Results Infection naïve nursing home residents reported fewer symptoms than previously infected residents: on average 1.9 and 3.1 symptoms, respectively (p = 0.016). The same effect was observed for infection naïve staff members and previously infected staff members (3.1 and 6.1 symptoms, respectively; p <0.0001). Moreover, the antibody development after a SARS-CoV-2 infection differs between residents and staff members, as previously infected residents tend to have a higher rate of asymptomatic cases compared to previously infected staff members (20.5% compared to 12.4%; p <0.0001). Conclusions We can postulate that COVID-19 disease development and symptomatology are different between a geriatric and younger population. Therefore, the occurrence and severity of a future ILI and/or ARI might vary from resident to staff.

Abstract
OBJECTIVES Assess the performance of five SARS-CoV-2 rapid serological tests (RST) using finger prick (FP) blood on-site to evaluate their usability for exposure assessment in population-based seroprevalence studies. STUDY DESIGN Since cross-reactivity with common cold human coronaviruses occurs, serological testing includes a risk of false-positive results. Therefore, the selected cohort for RST-validation was based on combined immunoassay (presence of specific antibodies) and RT-qPCR (presence of SARS-CoV-2) data. RST-performance for FP blood and serum was assessed by performing each RST in two groups, namely SARSCoV- 2 positive (n=108) and negative healthcare workers (n=89). Differences in accuracy and positive and negative predictive values (PPV, NPV) were calculated for a range (1-50%) of SARS-CoV-2 prevalence estimates. RESULTS The OrientGene showed overall acceptable performance, with sensitivities of 94.4% and 100%, and specificities of 96.6% and 94.4%, using FP blood and serum, respectively. Although three RST reach optimal specificities (100%), the OrientGene clearly outperforms in sensitivity. At a SARS-CoV-2 prevalence rate of 40%, this RST outperforms the other tests in NPV (96.3%) and reaches comparable PPV (94.9%). Although the specificity of the Covid-Presto is excellent when using FP blood or serum (100% and 97.8%, respectively), its sensitivity decreases when using FP blood (76.9%) compared to serum (98.1%). CONCLUSIONS Performances of the evaluated RST differ largely. Only one out of five RST (OrientGene) had acceptable sensitivity and specificity using FP blood. Therefore, the latter could be used for seroprevalence studies in a high-prevalence situation. The OrientGene, which measures anti-RBD antibodies, can be valuable after vaccination as well.

Abstract
BACKGROUND Long-term absenteeism continues to rise in Belgium and musculoskeletal disorders (MSDs) have been considered a primary cause. However, there is still uncertainty about the prevalence of MSDs, and about the contribution of work-related factors in the etiology of MSDs. SALTSA, which was developed in 2001, is a European diagnostic criterion document that aims to standardize the reporting of work-related upper limb MSDs (ULMSDs). The purpose of this work-site study was to implement SALTSA in daily occupational health practice and to determine the prevalence of ULMSDs in a Belgian company. METHODS During health examinations, occupational health nurses and an occupational health physician screened employees in a company with ergonomically high-risk activities for the occurrence of ULMSDs using the SALTSA protocol. In order to explore associations between ULMSDs and lifestyle and work-related factors, bivariate and logistic regression analyses were performed. FINDINGS Three hundred and eight (94.0%, 308/328) employees were screened resulting in an ULMSD prevalence of 20.5% (95% CI = [16.0-25.3]). Rotator cuff syndrome was the most common condition. Prevalence varied significantly between men (9.6%, 95% CI = [5.6-14.9]) and women (35.0%, 95% CI = [26.9-43.9]). Being female (p < .001) and working in the cabling assembly unit (p = .002) were found to be significant predictors of ULMSDs. CONCLUSION/APPLICATION TO PRACTICE By using the SALTSA protocol in occupational health practices, ULMSDs can be screened unequivocally, enabling comparisons between different occupational sectors and countries. Occupational health nurses can play an important role in detecting and screening MSDs among workers.

Abstract
OBJECTIVE To identify early symptoms allowing rapid appraisal of infection with SARS-CoV-2 among healthcare workers of a large Belgian hospital. METHODS Healthcare workers with mild symptoms of an acute respiratory tract infection were systematically screened on clinical characteristics of corona virus disease 2019 (COVID-19). A nasopharyngeal swab was taken and analyzed by real-time Reverse-Transcription-Polymerase-Chain-Reaction (rRT-PCR). RESULTS Fifty percent of 373 workers tested COVID-19 positive. The symptoms cough (82%), headache (78%), myalgia (70%), loss of smell or taste (40%), and fever more than or equal to 37.5 °C (76%) were significantly higher among those infected. CONCLUSION Where each individual symptom contributes to the clinical evaluation of possible infection, it is the combination of COVID-19 symptoms that could allow for a rapid diagnostic appraisal of the disease in a high prevalence setting. Early transmission control is important at the onset of an epidemic.

Abstract
OBJECTIVES Few studies focus on out-of-hospital cardiac arrests in the occupational setting. Therefore, this study describes the presence and use of an automated external defibrillator (AED) at Belgian workplaces during the period 2012-2014. MATERIAL AND METHODS A self-constructed questionnaire was developed and sent to internal prevention counselors. RESULTS In total, 767 companies filled out the questionnaire. An AED was available in 48.8% of the companies. Presence mainly depended on the number of persons present in the company (both workers and non-workers (e.g., visitors, clients)) and on some occupational cardiovascular risks but was often not based on a well-conducted risk analysis. Training of workers and AED maintenance were provided appropriately. An AED was used for shocking 23 times of which 10 persons survived. CONCLUSIONS Acquiring an AED in the occupational setting is seldom based on a well-conducted risk analysis. Therefore, instructions and criteria are needed to come to a rational decision. Furthermore, a registry on AED utilization in the workplace (e.g., with data on long-term survival) should be set up. Int J Occup Med Environ Health 2018;31(5):603-611.

Abstract
Background Healthcare provider (HCP) activities and attitudes towards patients strongly influence medication adherence. The aim of this study was to assess current clinical practices to support patients in adhering to treatment with oral anticancer agents (OACA) and to explore clues to improve the management of medication adherence. Methods A cross-sectional, observational study among HCPs in (haemato-)oncology settings in Belgium and the Netherlands was conducted in 2014 using a composite questionnaire. A total of 47 care activities were listed and categorised into eight domains. HCPs were also asked about their perceptions of adherence management on the items: insight into adherence, patients’ communication, capability to influence, knowledge of consequences and insight into causes. Validated questionnaires were used to assess beliefs about medication (BMQ) and shared decision making (SDM-Q-doc). Results In total, 208 HCPs (29% male) participated; 107 from 51 Dutch and 101 from 26 Belgian hospitals. Though a wide range of activities were reported, certain domains concerning medication adherence management received less attention. Activities related to patient knowledge and adverse event management were reported most frequently, whereas activities aimed at patient’s self-efficacy and medication adherence during ongoing use were frequently missed. The care provided differed between professions and by country. Belgian physicians reported more activities than Dutch physicians, whereas Dutch nurses and pharmacists reported more activities than Belgian colleagues. The perceptions of medication adherence management were related to the level of care provided by HCPs. SDM and BMQ outcomes were not related to the care provided. Conclusions Enhancing the awareness and perceptions of medication adherence management of HCPs is likely to have a positive effect on care quality. Care can be improved by addressing medication adherence more directly e.g., by questioning patients about (expected) barriers and discussing strategies to overcome them, by asking for missed doses and offering (electronic) reminders to support long-term medication adherence. A multidisciplinary approach is recommended in which the role of the pharmacist could be expanded.

Abstract
BACKGROUND Little is known about healthcare providers' (HCPs) perceptions of adherence management of oral anticancer agents (OACA). The study aims to explore HCPs perceptions of OACA and adherence. METHODS A cross-sectional, multi-center observational study among HCPs in hemato-oncology settings in Belgium and the Netherlands was conducted. Physicians, nurse practitioners, nurses and pharmacists were asked to complete questionnaires on their perception of patient adherence and its management (PAMQ) and their beliefs about OACA (BMQ-Specific). Physicians were also asked to complete a questionnaire on their perception of shared decision making (SDM-Q-Doc). RESULTS The sample consisted of 254 HCPs. Variations were found between HCPs on the PAMQ: 56%, 50%, 28% and 23% of, respectively, physicians, nurse practitioners, nurses and pharmacists reported to know the level of adherence of their patients and 59%, 53%, 43% and 10% of, respectively, physicians, nurse practitioners, nurses and pharmacists think that patients discuss adherence with them. 70%, 82%, 63% and 62% of, respectively, physicians, nurse practitioners, nurses and pharmacists reported to have knowledge of causes of non-adherence, while 78%, 87%, 76% and 80% of them reported to have knowledge of consequences of non-adherence. 81%, 92%, 83% and 67% of, respectively, physicians, nurse practitioners, nurses and pharmacists felt able to influence adherence. Lower concerns beliefs were associated with a higher total score on the PAMQ [β (SE)=-0.85 (0.24); CI -1.33--0.38]. Physicians scored a mean of 75 on the SDM-scale. CONCLUSIONS A considerable part of the HCPs states they do not know the adherence of their patients, nor do they think patients discuss adherence with them. However, they feel to have knowledge of adherence and perceive to be able to influence adherence of their patients.

Abstract
Background The European Agency for Safety and Health at Work (EU-OSHA) is developing an online e-guide, which will provide tips and practical information for each EU country (in their national language(s)) on ageing and occupational health and safety. The e-guide will be launched in 2016 as part of the EU-OSHA campaign on Healthy Workplaces for all ages. The e-guide will present evidence, tools and practical examples of how companies can take action and effectively promote sustainable employability. Methods As part of the development of the e-guide, a cross-sectional study was conducted to survey Belgian employers in April 2015 to determine their specific needs concerning older workers’ occupational health and safety issues. Researchers from Milieu Ltd. (Brussels, Belgium), the consultancy company coordinating the e-guide project, and Mensura Occupational Health Services (Brussels, Belgium) developed a 13-item questionnaire. The survey addressed the needs and importance given to sustainable employability of older workers in Belgian companies and evaluated corporate knowledge regarding relevant national policies. The questionnaire was distributed electronically to the management of 22,084 private-sector companies affiliated with Mensura. Results Ten percent (n = 2133) of recipients opened the e-mail, and 37 % (n = 790) of these completed the questionnaire. In 89 % of the responding companies, sustainable employability of workers aged ≥55 years plays an important role; 70 % have no active sustainable employability policy/initiative; 18 % experience difficulties promoting sustainable employability; and 86 % indicate no need for support to promote sustainable employability. Respondents noted the following health complaints among workers aged ≥55 years: work-related health problems (31 %), stress (26 %), work agreements/type of work (17 %), work/life balance (15 %), and career development and/or training (9 %). Topics concerning health and well-being of workers aged ≥55 years requiring the most attention include motivation (30 %) and adaptation of the workplace to their health requirements (26 %). Conclusions The e-guide should raise further awareness among employers about the importance of implementing an active sustainable employability policy to prolong working life in a healthy and productive way. The e-guide should also include tools to address work-related health problems and stress, motivation, and adaptation of the workplace to the health requirements of workers aged ≥55 years.

Abstract
Non-adherence and non-persistence in breast cancer patients taking antihormonal therapy (AHT) is common. However, the complex patterns and dynamics of adherence and persistence are still not fully understood. This study aims to give insight into the process of (non-)adherence and (non-)persistence by researching influencing factors and their interrelatedness in breast cancer patients taking AHT by means of a qualitative study with semi-structured interviews. The sample consisted of 31 breast cancer patients treated with AHT. Purposive and theoretical sampling and the constant comparison method based on a grounded theory approach were used. Expectations regarding the impact of AHT, social support from family and friends, and recognition from healthcare professionals were found to influence the process of non-adherence and non-persistence. The results of this study can help healthcare professionals understand why breast cancer patients taking AHT do not always adhere to or persist in taking the therapy and may facilitate patient-tailored interventions.

Abstract
CONTEXT Symptom control is an essential part of palliative care and important to achieve optimal quality of life. Studies showed that patients with all types of advanced cancer suffer from diverse and often severe symptoms. Research focusing on older persons is scarce because this group is often excluded from studies. Consequently, it is unclear which symptoms older palliative care patients with cancer experience and what is the prevalence of these symptoms. To date, no systematic review has been performed on the prevalence of symptoms in older cancer patients receiving palliative care. OBJECTIVES The objective of this systematic review was to search and synthesize the prevalence figures of symptoms in older palliative care patients with cancer. METHODS A systematic search through multiple databases and other sources was conducted from 2002 until April 2012. The methodological quality was evaluated. All steps were performed by two independent reviewers. A meta-analysis was performed to pool the prevalence of symptoms. RESULTS Seventeen studies were included in this systematic review. Thirty-two symptoms were identified. The prevalence of these symptoms ranged from 3.5% to 77.8%. The most prevalent symptoms were fatigue, excretory symptoms, urinary incontinence, asthenia, pain, constipation, and anxiety and occurred in at least 50% of patients. CONCLUSION There is a high degree of uncertainty about the reported symptom prevalence because of small sample sizes, high heterogeneity among studies, and the extent of instrument validation. Research based on rigorous methods is needed to allow more conclusive results.

Abstract
BACKGROUND & AIMS Malnutrition is a common problem in the elderly living in nursing homes. A clear understanding of associated factors is missing. The aim of this study was to evaluate prevalence of malnutrition and to determine factors independently associated with malnutrition in this setting. METHODS A cross-sectional, multi-centre study was conducted in 23 nursing homes in Flanders, Belgium. The nutritional status was assessed using the Mini Nutritional Assessment (MNA). Data on possible associated factors were collected using validated scales. RESULTS The study included 1188 elderly residents; 38.7% were at risk for malnutrition and 19.4% were malnourished. The presence of a wound/pressure ulcer, a recent hospitalization (<3 months ago), being involved in a tailored nutritional intervention, and suffering from a lower cognitive state were significantly associated with malnutrition. Receiving additional meals provided by family members was negatively associated with malnutrition. CONCLUSION Malnutrition is a prevalent problem in nursing homes in Flanders. Systematic screening and well-defined tailored interventions should be further developed and evaluated in this population at risk.
