Is There a Gender Gap in the Birthday-Number Effect? The Case of Lotto Players and the Role of Sequential Choice.

The literature on lottery gambling shows that players do not select numbers randomly, a phenomenon which is called conscious selection. Mainly, players prefer "small" numbers (less than thirty), either because of the existence of small lucky numbers or because they are victims of the so-called birthday-number effect. Because lotto games are parimutuel, such preferences result in poor ticket choices in terms of achieving below average returns.

Number 19: Another Victim of the COVID-19 Pandemic?

Conscious selection is the mental process by which lottery players select numbers nonrandomly. In this paper, we show that the number 19, which has been heard, read, seen, and googled countless times since March 2020, has become significantly less popular among Belgian lottery players after the World Health Organization named the disease caused by the coronavirus SARS-CoV-2 "COVID-19". We argue that the reduced popularity of the number 19 is due to its negative association with the COVID-19 pandemic.

Superstitious beliefs, locus of control, and feeling at risk in the face of Covid-19.

Unprecedented uncertainty during the Covid-19 pandemic stimulated anxiety among individuals, while the associated health restrictions contributed to a feeling of loss of control. Prior research suggests that, in times of crisis, some individuals rely on superstitious beliefs as a coping mechanism, but it remains unclear whether superstition is positively or negatively associated with fear of Covid-19 during the pandemic, and the role that individuals' locus of control plays in this regard. In two studies conducted among individuals in Belgium and the U.

Pilot study of a 10-week multidisciplinary Tai Chi intervention in sedentary obese women.

Objective: Alternative approaches to weight control and physical activity are increasingly needed. Numerous factors influence weight management, including the choice of physical exercise. No study has previously examined the therapeutic effect of a multidisciplinary weight management program incorporating Tai Chi (TC) exercises among sedentary obese women.

Reevaluation of the combined dexamethasone suppression-corticotropin-releasing hormone test for differentiation of mild cushing's disease from pseudo-Cushing's syndrome.

Context: The diagnostic accuracy of the combined dexamethasone suppression test (DST)-CRH test for the differential diagnosis between Cushing's disease (CD) and pseudo-Cushing syndrome (PCS) has recently been debated.

Objective: Our objective was to reevaluate the performance of the DST-CRH test to differentiate CD from PCS and compare it with that of midnight plasma cortisol measurement.

Setting: The study took place at three specialized tertiary care university hospitals.

Corticosteroid binding globulin gene polymorphism influences cortisol driven fat distribution in obese women.

Hypothalamo-pituitary-adrenal axis has been reported to influence fat mass distribution in obesity. We investigated the hypothesis that corticosteroid-binding globulin (CBG) polymorphism could influence obesity, metabolic, or hypothalamo-pituitary adrenal (HPA) axis activity parameters. In 44 obese pre-menopausal women, a microsatellite located within the CBG gene was analyzed, providing three genotypes: 86/86 (n = 29), 86/90 (n = 14), and 90/90 (n = 1).

Increased cortisol bioavailability, abdominal obesity, and the metabolic syndrome in obese women.

Objective: This study was conducted to obtain a detailed profile of hypothalamo-pituitary-adrenal (HPA) axis activity and reactivity and its differential relationships with body fat distribution and total fat mass in premenopausal obese women.

Research Methods And Procedures: Cortisol responses to stimulation (awakening, food intake, exercise) and suppression (0.25 mg dexamethasone), cortisol metabolism, and tissue sensitivity to glucocorticoids were studied in 53 premenopausal obese women grouped according to their waist-to hip ratio: women with abdominal body fat distribution (A-BFD; n = 31) and women with peripheral fat distribution (P-BFD; n = 22).

Pituitary magnetic resonance imaging findings do not influence surgical outcome in adrenocorticotropin-secreting microadenomas.

The pituitary origin of ACTH secretion in ACTH-dependent hypercortisolism can be difficult to assess, as magnetic resonance imaging (MRI) frequently fails to identify ACTH-secreting microadenomas or, on the contrary, may give false positive images of microadenomas. The choice of therapeutic option for patients with such normal MRI findings is controversial. Some groups propose routinely pituitary surgery, whereas others consider that neurosurgical exploration may be less successful and more harmful, and therefore prefer other types of management.

Occult Cushing's syndrome in type-2 diabetes.

Subclinical Cushing's syndrome (SCS) caused by adrenal incidentalomas is frequently associated with overweight and insulin resistance. Metabolic syndrome X may therefore be a clue to the presence of CS. However, the incidence of CS in this situation remains unknown.
