Multiple sclerosis (MS) is an autoimmune-mediated neurodegenerative disease of the central nervous system characterized by inflammatory demyelination with axonal transection. MS affects an estimated 900 000 people in the US. MS typically presents in young adults (mean age of onset, 20-30 years) and can lead to physical disability, cognitive impairment, and decreased quality of life. This review summarizes current evidence regarding diagnosis and treatment of MS.

MS typically presents in young adults aged 20 to 30 years with unilateral optic neuritis, partial myelitis, sensory disturbances, or brainstem syndromes such as internuclear ophthalmoplegia developing over several days. The prevalence of MS worldwide ranges from 5 to 300 per 100 000 people and increases at higher latitudes. Overall life expectancy is less than in the general population (75.9 vs 83.4 years), and MS more commonly affects women (female to male sex distribution of nearly 31). Diagnosis is made based on a combination of signs and symptannualized relapse rates compared with placebo or active comparators, range from 29%-68%. Adverse effects include infections, bradycardia, heart blocks, macular edema, infusion reactions, injection-site reactions, and secondary autoimmune adverse effects, such as autoimmune thyroid disease.

MS is characterized by physical disability, cognitive impairment, and other symptoms that affect quality of life. Treatment with DMT can reduce the annual relapse rate by 29% to 68% compared with placebo or active comparator.

Unhealthy alcohol use can lead to agitation in the intensive care unit (ICU).

To assess whether high-dose baclofen reduces agitation-related events compared with placebo in patients with unhealthy alcohol use receiving mechanical ventilation.

This phase 3, double-blind, placebo-controlled, randomized clinical trial conducted in 18 ICUs in France recruited adults receiving mechanical ventilation who met criteria for unhealthy alcohol use. Patients were enrolled from June 2016 to February 2018; the last follow-up was in May 2019.

Baclofen (n = 159), adjusted from 50 to 150 mg per day based on estimated glomerular filtration rate, or placebo (n = 155) during mechanical ventilation up to a maximum of 15 days before gradual dose reduction over 3 to 6 days.

The primary end point was the percentage of patients with at least 1 agitation-related event over the treatment period. Secondary outcomes included duration of mechanical ventilation, length of ICU stay, and 28-day mortality.

Among 314 patients who wsation of sedatives and analgesics) occurred in 14 patients (8.9%) in the baclofen group vs 3 (1.9%) in the placebo group.

Among patients with unhealthy alcohol use receiving mechanical ventilation, treatment with high-dose baclofen, compared with placebo, resulted in a statistically significant reduction in agitation-related events. However, considering the modest effect and the totality of findings for the secondary end points and adverse events, further research is needed to determine the possible role of baclofen in this setting and to potentially optimize dosing.

Exfoliation syndrome is a systemic disorder characterized by progressive accumulation of abnormal fibrillar protein aggregates manifesting clinically in the anterior chamber of the eye. This disorder is the most commonly known cause of glaucoma and a major cause of irreversible blindness.

To determine if exfoliation syndrome is associated with rare, protein-changing variants predicted to impair protein function.

A 2-stage, case-control, whole-exome sequencing association study with a discovery cohort and 2 independently ascertained validation cohorts. Study participants from 14 countries were enrolled between February 1999 and December 2019. The date of last clinical follow-up was December 2019. Bupivacaine Affected individuals had exfoliation material on anterior segment structures of at least 1 eye as visualized by slit lamp examination. Unaffected individuals had no signs of exfoliation syndrome.

Rare, coding-sequence genetic variants predicted to be damaging by bioinformatic algorithms trained to recognize aln this whole-exome sequencing case-control study, presence of exfoliation syndrome was significantly associated with carriage of functionally deficient CYP39A1 sequence variants. Further research is needed to understand the clinical implications of these findings.

Sepsis is a common syndrome with substantial morbidity and mortality. A combination of vitamin C, thiamine, and corticosteroids has been proposed as a potential treatment for patients with sepsis.

To determine whether a combination of vitamin C, thiamine, and hydrocortisone every 6 hours increases ventilator- and vasopressor-free days compared with placebo in patients with sepsis.

Multicenter, randomized, double-blind, adaptive-sample-size, placebo-controlled trial conducted in adult patients with sepsis-induced respiratory and/or cardiovascular dysfunction. Participants were enrolled in the emergency departments or intensive care units at 43 hospitals in the United States between August 2018 and July 2019. After enrollment of 501 participants, funding was withheld, leading to an administrative termination of the trial. All study-related follow-up was completed by January 2020.

Participants were randomized to receive intravenous vitamin C (1.5 g), thiamine (100 mg), and hydrocortisone (50 mg) every 6 ys) in the intervention group and 26 days (IQR, 0-28 days) in the placebo group, with a median difference of -1 day (95% CI, -4 to 2 days; P = .85). Thirty-day mortality was 22% in the intervention group and 24% in the placebo group.

Among critically ill patients with sepsis, treatment with vitamin C, thiamine, and hydrocortisone, compared with placebo, did not significantly increase ventilator- and vasopressor-free days within 30 days. However, the trial was terminated early for administrative reasons and may have been underpowered to detect a clinically important difference.
