The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy spectra and rates. For charged current events, assuming an undistorted 8B spectrum, the night minus day rate is 14.0%+/-6.3%(+1.5%)(-1.4%) of the average rate. If the total flux of active neutrinos is additionally constrained to have no asymmetry, the nu(e) asymmetry is found to be 7.0%+/-4.9%(+1.3%)(-1.2%). A global solar neutrino analysis in terms of matter-enhanced oscillations of two active flavors strongly favors the large mixing angle solution.

Background: Sleep and circadian disruption are associated with increased dementia risk, yet the mechanism remains poorly understood. We examined the relationship between night/shift working in the fourth decade and late-life brain health. We explored whether significant relationships were mediated by life course factors including cardiovascular risk.

Extra-cavitary primary effusion lymphoma (PEL), often associated with human herpes virus 8 (HHV8) infection, represents a rare and aggressive form of non-Hodgkin lymphoma, which is predominantly found in individuals with severe immunosuppression. As an acquired immunodeficiency syndrome (AIDS)-associated lymphoma, PEL typically manifests in the context of advanced human immunodeficiency virus (HIV) infection, requiring tailored therapeutic approaches to manage both the lymphoma and underlying immunodeficiency. A 53-year-old male patient from Cape Verde presented with a three-day history of fever, night sweats, right iliac fossa pain, hematochezia, and an unintentional weight loss of five kilograms over the previous two months.

Background: The noise levels in intensive care units usually exceed the recommended limits in (inter)national recommendations. Such noise levels can affect both the recovery of intensive care patients and the performance of staff. The aim of this study was to reduce ward-based noise levels in three intensive care units (anesthesiological, neurological, and neonatological).

The exposure of the general population to artificial light at night has dramatically increased in recent decades. Current standards for domestic lighting are based on acute exposure to light and consider blue wavelengths to be responsible for phototoxicity. However, meta-analyses pointed out the role of lifelong light exposure in the onset of age-related macular degeneration, suggesting a cumulative effect of light exposure.

Background: Problematic Internet use (PIU) is a growing concern in modern society. There is a limitation of epidemiologic data related to PIU. This is due to a lack of consensus on the definition and variability of assessment tools of PIU.
