Background: Hospital patient room surfaces are frequently contaminated with multidrug-resistant organisms. Since studies have demonstrated that inadequate terminal room disinfection commonly occurs, ..úno touch..Ñ methods of terminal room disinfection have been developed such as ultraviolet light (UV) devices and hydrogen peroxide (HP) systems.
Methods: This paper reviews published clinical trials of ..úno touch..Ñ methods and ..úself-disinfecting..Ñ surfaces.
Results: Multiple papers were identified including clinical trials of UV room disinfection devices (N.ß=.ß20), HP room disinfection systems (N.ß=.ß8), handheld UV devices (N.ß=.ß1), and copper-impregnated or coated surfaces (N.ß=.ß5). Most but not all clinical trials of UV devices and HP systems for terminal disinfection demonstrated a reduction of colonization/infection in patients subsequently housed in the room. Copper-coated surfaces were the only ..úself-disinfecting..Ñ technology evaluated by clinical trials. Results of these clinical trials were mixed.
Discussion: Almost all clinical trials reviewed used a ..úweak..Ñ design (eg, before-after) and failed to assess potential confounders (eg, compliance with hand hygiene and environmental cleaning).
Conclusions: The evidence is strong enough to recommend the use of a ..úno-touch..Ñ method as an adjunct for outbreak control, mitigation strategy for high-consequence pathogens (eg, Candida auris or Ebola), or when there are an excessive endemic rates of multidrug-resistant organisms.

Department of Pharmacovigilance, Pharmacovigilance and Quality Assurance Group, Torii Pharmaceutical Co., Ltd., Tokyo, Japan.
Standardized quality (SQ) house-dust mite (HDM) sublingual immunotherapy tablets (10,000 Japanese allergy units [JAU], equivalent to 6 SQ-HDM in Europe and the United States) are licensed for the treatment of HDM-induced allergic rhinitis (AR) without age restriction, based on 52-week administration clinical trials. There are no large-scale data on the administration of 10,000 JAU for > 1 year in actual clinical practice. To examine the safety and effectiveness of 10,000 JAU during use for up to 3 years at real-world clinical sites in Japan.

Remission of asthma can occur as part of the natural history of the disease; however, the use of biologics can result in disease remission in some patients. In this post hoc analysis of the RELIght study, we aimed to evaluate clinical remission in real life among patients treated with mepolizumab, to detect possible differences between "remitters" and "nonremitters," and to evaluate possible predictors of remission. Clinical remission was defined as the absence of asthma exacerbations, discontinuation of oral corticosteroids (OCS), achievement of asthma control (Asthma Control Test [ACT] ≥ 20), and stable or improved lung function.

To evaluate the association of parenteral epinephrine and terbutaline use on ventilatory support in children admitted to the intensive care unit (ICU) with critical asthma in the United States. Data were obtained from the Pediatric Health Information System data base for children ages 2 to 18 years admitted to the ICU with a diagnosis of asthma exacerbation from January 1, 2016, to December 31, 2023. The primary outcomes included noninvasive ventilation (NIV) and/or invasive mechanical ventilation (IMV) use after receipt of terbutaline and/or epinephrine.

Allergen immunotherapy (AIT) is currently the most effective immunologic form of treatment for patients with atopic allergic diseases commonly used by allergist/immunologists to reduce allergic symptoms by gradually desensitizing the immune system to specific allergens. Currently, the primary mechanism of AIT emphasizes the crucial role of immune regulation, which involves a shift from a T-helper type 2 (Th2) cell response, which promotes allergy, to a T-regulatory (Treg) cell population, which inhibits the allergic inflammatory response through the production of immunosuppressive cytokines interleukin 10 and transforming growth factor β, which play pivotal roles in suppressing the allergic reaction. In a series of previous in vitro and in vivo experiments, we have demonstrated the capacity of synthetic methylated cytosine-phosphate-guanine (CpG) oligodeoxynucleotide (ODN) moieties as well as methylated genomic DNA ODN motifs from Bifidobacterium longum subspecies infantis to activate Treg cell differentiation in contrast to the unmethylated ODN moiety, which promotes proinflammatory responses driven by Th17-mediated responses.
