Introduction: Gulf War Illness (GWI) currently has no known cure and affects soldiers deployed during the Persian Gulf War. It is thought to originate from exposure to neurotoxicants combined with battlefield stress, and previous research indicates that treatment first involves inhibition of interleukin-2 and tumor necrosis factor alpha, followed by the glucocorticoid receptor. However, the off-target effects of pharmaceuticals hinder development of a drug treatment therapy.
Materials And Methods: AutoDock 4.2, AutoDock Vina, and Schrodinger's Glide were used to perform consensus docking, a computational technique where pharmaceuticals are screened against targets using multiple scoring algorithms to obtain consistent binding affinities. FDA approved pharmaceuticals were docked against the above-mentioned immune and stress targets to determine a drug therapy for GWI. Additionally, the androgen and estrogen targets were screened to avoid pharmaceuticals with off-target interactions.
Results: While suramin bound to both immune targets with high affinity, top binders of the hormonal and glucocorticoid targets were non-specific towards their respective proteins, possibly due to high structure similarity between these proteins.
Conclusions: Development of a drug treatment therapy for GWI is threatened by the tight interplay between the immune and hormonal systems, often leading to drug interactions. Increasing knowledge of these interactions can lead to break-through therapies.

Background: Gulf War Illness (GWI) is a chronic multi-symptom illness that affects up to one-third of the 700,000 American military personnel deployed to the Persian Gulf region in 1990 and 1991. We conducted a randomized controlled trial to examine feasibility and the relative efficacy of two 12-week in-person group treatments (Tai Chi and Wellness) to address GWI symptoms of chronic pain, fatigue, and changes in mood and cognitive functioning.
Method: Male and female veterans were randomly assigned to Tai Chi (n = 27) or Wellness (n = 26) group interventions and assessed at four time points: baseline, post-treatment, 3-, and 9-month follow-up.
Gulf war illness is a chronic multisymptom disorder that affects as many as many as 25-35% of the military personnel who were sent to the Persian Gulf war in 1991. The illness has many debilitating symptoms, including cognitive problems, gastrointestinal symptoms, and musculoskeletal pain. Those so afflicted have been sick for more than 30 years and, therefore, it has become imperative to understand the etiology and then produce treatments to ease the symptoms.

However, continuous direct observational records during the past two decades have shown remarkable resilience of the AMOC. To shed light on this apparent contradiction, here we attempt to attribute the interdecadal variation of the historical AMOC to the anthropogenic and natural signals, by analyzing multiple climate and surface-forced ocean model simulations together with direct observational data.

Background And Purpose:
Post-COVID condition (also known as long COVID) is a syndrome characterized by persistent symptoms following a suspected or confirmed SARS-CoV-2 infection, lasting for at least two months and are not attributable to other conditions. The most common symptoms include fatigue, diffuse pain, post-exertional malaise and “brain fog” (impairment of memory and concentration). The pathomechanism of long COVID is the subject of ongoing, intensive research.

Using 20 years of longitudinal data from Gulf War Veteran and Era personnel from the Millennium Cohort Study (2001-2021; n=45381), Cox proportional hazard models estimated the relative effects of Gulf War service status, CMI, and their corresponding interaction on all-cause mortality. Although age- and sex-adjusted mortality ratios suggested that Gulf War Veterans had higher mortality rates than Era personnel, no association was observed between Gulf War service status and mortality risk.
