Loneliness is prevalent among sexual minority adults and is associated with minority stress. Yet there is limited understanding of how loneliness and minority stress vary across key demographic variables. This cross-sectional study explored age and gender differences in a minority stress model linking sexual orientation marginalization to social and emotional loneliness via proximal stress (internalized homonegativity, concealment, and stigma preoccupation) and via social anxiety and inhibition.

Objectives: Moroccan and Turkish migrants residing in Northwestern Europe have high loneliness levels. This study examines gender differences in loneliness within this migrant population. The migrants have gender-segregated social roles at home and in public, which might lead to gender differences in what aspects of social relationships can explain variation in loneliness.

Service providers may experience difficulties in providing appropriate care to optimize the functioning of individuals with intellectual disability and challenging behaviour. External consultation to identify and address the unmet support needs underlying the behaviour may be beneficial. Applying the multidimensional American Association Intellectual and Developmental Disabilities (AAIDD) model may facilitate this approach.

Introduction: Children often present to primary care with functional abdominal pain (FAP) or irritable bowel syndrome (IBS), and around half still have abdominal complaints 1 year later. Hypnotherapy is an evidence-based treatment that is used in specialist care, but it lacks evidence in primary care. This study will investigate the (cost) effectiveness of home-based guided hypnotherapy for children with FAP or IBS in primary care.

So far, little attention has been paid to contextual factors shaping loneliness and their interaction with individual characteristics. Moreover, the few existing studies have not included older migrants, identified as a group who are vulnerable to loneliness. This study examined the association between neighbourhood ethnic density (the proportion of own-group residents and the proportion of other ethnic residents in an area) and loneliness among older migrants.

Individual socioeconomic status has a significant impact on whether older adults can initiate and maintain social relationships and participate in society, hence it affects loneliness. At the macro level, income inequality is expected to increase the risk of loneliness by eroding social cohesion and trust, while welfare generosity might protect people from loneliness. The aim of the study is to explore whether income inequality and welfare generosity at the country level moderate the effect of socioeconomic status at the individual level on late-life loneliness.

Objectives: According to guidelines, the autogenous saphenous vein (ASV) is the preferred conduit for femoropopliteal bypass surgery in all patients with peripheral artery disease. However, in contrast to patients with critical limb ischemia (CLI), patients with intermittent claudication (IC) only, tend to have milder disease, and thus a prosthetic graft may be as good as a vein conduit. The objective of this study was to compare patency rates of the ASV and a prosthetic graft in femoropopliteal bypass surgery in patients with IC.

Research suggests that loneliness among sexual minority adults is associated with marginalization, but it is unclear which processes may underlie this relationship. This cross-sectional study examined five possibilities: stigma preoccupation, internalized homonegativity, sexual orientation concealment, social anxiety, and social inhibition. The study also examined the possible protective role of LGBTQ community involvement.

The topic of loneliness among older migrants has recently gained scholarly interest. There is a particular focus on why older migrants are generally lonelier than their non-migrant peers from the destination. These studies neglect variations both within and between older migrant groups.

While activity participation in later life has attracted considerable attention from policymakers and scholars, indoor and outdoor engagement among older Chinese migrants in Europe is understudied. Using in-depth interviews with 21 older Chinese migrants in the Netherlands and seven in Belgium, this study is among the first to explore older Chinese migrants' activity participation experiences from the perspective of Confucianism, the cornerstone of Chinese culture. More specifically, the impact of four acknowledged principles of Confucianism are considered: hierarchical relationships, family system, benevolence and emphasis on education.

Older migrants may be one of the most vulnerable populations during the coronavirus pandemic, yet the degree of impact remains largely unknown. This study explores (1) the consequences of the coronavirus pandemic for older Chinese migrants in Belgium and the Netherlands in terms of increased loneliness and its risk factors (reduced in-person contact, decreased social participation, feelings of existential threat) and protective factors (increased non-in-person contact, more individual activities), and (2) which risk and protective factors have contributed to the incidence and prevention of higher loneliness levels. Using quantitative data of a survey among 98 Chinese migrants aged 50 years and older in Belgium ( = 84) and the Netherlands ( = 14), the findings first indicate that the coronavirus pandemic has a significant impact on older Chinese migrants' lives.

Nitrous oxide (N2O) is increasingly used as a recreational drug, and is presumed relatively safe and innocent. The risks for neurological complications are often known, however the risks of serious thromboembolic events are not. We describe three cases of acute thromboembolic events resulting in serious cardiovascular complications after N2O abuse: one case of myocardial infarction that resulted in a reduced ejection fraction, one case of peripheral arterial occlusion that led to limb amputation and one case of pulmonary embolism that resulted in hemodynamic instability requiring extracorporeal membrane oxygenation (ECMO) and surgical removal.

Background: Achilles tendinopathy (AT) occurs in half of the elite runners. AT is a difficult-to-treat tendon disease, which may progress from new onset to a chronic state. It is unknown how many runners with new-onset AT develop persisting symptoms and which prognostic factors are associated with this course.

Introduction: Running-related injuries (RRIs) are frequent, but no effective injury prevention measures have been identified yet. Therefore, we have set up the INSPIRE trial in 2017, in which the effectiveness of an online injury prevention programme was tested. Although this programme was not effective in reducing the number of RRIs, we gained new insights from this study, which we used to design an enhanced, online multidisciplinary injury prevention programme.

Objective: Examine the associations of training volume and longest endurance run with (half-)marathon performance and running-related injuries (RRIs) in recreational runners.

Materials And Methods: During the preparation for and directly after the running event, 556 participants of a half marathon and 441 participants of a marathon completed three questionnaires on RRIs, average weekly training volume and the longest endurance run. With finish time, decline in pace during the running event and RRIs as dependent variables, linear and logistic regression analyses were performed to test the associations with weekly training volume and the longest endurance run.

The prevalence of loneliness among Turkish-Dutch and Moroccan-Dutch older adults is higher than among Dutch older adults of non-migrant origin. Three explanations may account for this difference: (1) differential item functioning might result in scores that vary in intensity and in meaning across categories; (2) the position of migrants is much more vulnerable than that of non-migrants; (3) the lack of protective factors has more severe consequences for older migrants. The Longitudinal Aging Study Amsterdam interviewed 176 persons born in Morocco and 235 born in Turkey, aged 55-66 and living in urban areas.
