AI Article Synopsis

  • The review emphasizes the potential benefits of using microbial-based interventions, like probiotics, alongside food allergen immunotherapy to improve its safety and effectiveness.
  • Recent animal studies suggest that these microbial therapies can help prevent allergic reactions and enhance treatment success by promoting specific immune responses.
  • Ongoing research aims to translate these promising preclinical findings into human clinical applications, highlighting the need for a deeper understanding of how these microbial adjuncts work and careful trial designs for testing them.

Article Abstract

Purpose Of Review: Food allergen immunotherapy may benefit from adjunct therapies to enhance safety and efficacy. We review preclinical studies investigating the effects of probiotics and other microbial-based interventions on oral tolerance, describe the human clinical trial evidence thus far for microbial adjuncts, and discuss steps for translating research findings in this area to clinical therapy.

Recent Findings: Murine studies support that microbial-based interventions confer protection against sensitization and may augment treatment efficacy for food allergy. Microbial adjunct therapies can promote regulatory T cells and modulate Th1 vs. Th2 responses. There is a wide array of novel modalities utilizing microbial components. Ongoing efforts are focused on translating preclinical data into potential treatments. Probiotics, prebiotics, and microbial components have all been examined as microbial adjunct therapies in murine models of food allergy. The effects of probiotics appear to be strain-specific. Prebiotics and bacterial components are innovative modalities to modulate oral tolerance. Better characterization of dysbiosis in human cohorts with food allergy, deeper mechanistic understanding of microbial adjunct therapies, safety evaluation, and careful clinical trial design will be crucial for the development of microbial adjuncts for food allergen immunotherapy. Microbial adjunct therapies have the potential to enhance the efficacy, safety, and durability of food allergen immunotherapy.

Comparison of different treatment positions of nerve slider technique for patients with low back pain: a randomized control trial.

Eur J Phys Rehabil Med

January 2025

Department of Physiotherapy and Rehabilitation, Faculty of Health Sciences, European University of Lefke, Mersin, Türkiye.

Background: Low back pain (LBP) accompanied by sciatica is a widespread musculoskeletal issue with multifactorial etiology, impacting individuals across various demographics. Conservative treatments, notably physiotherapy, are key in managing LBP with sciatica, with neural mobilization techniques emerging as beneficial adjuncts.

Aim: This research aims to assess the effectiveness of utilizing the sciatic slider technique (SST) in both supine and slump positions, compared to conventional physiotherapy alone, in alleviating pain severity, improving lumbar flexibility, lumbar lordosis, lower limb muscle strength, and functional ability in patients with LBP associated with sciatica.

Objective: This study aimed to assess the effects of kinesiotaping (KT) adjunct to physical therapy (PT) on proprioception, cervical range of motion (ROM), pain, disability, anxiety, depression, and quality of life (QoL) in cervical spondylosis.

Methods: Sixty-nine patients aged 50-70 years were randomized into three groups: PT, PT plus KT(PT+KT), PT plus sham-taping(PT+ST). All participants underwent standardized 15-session PT, 5 days/week.

Objective: This study evaluated the safety and efficacy of isoproterenol administration as an adjunct for achievement of target heart rate (HR) during dobutamine stress echocardiography (DSE).

Background: In DSE, optimal accuracy is achieved when a target HR of 85% of maximal predicted heart rate (MPHR) is attained. Although rarely studied, intravenous isoproterenol has been used as an adjunct therapy to dobutamine and atropine to increase chronotropic response during pharmacologic stress testing.

Introduction: Hyperthermia is an established adjunct in multimodal cancer treatments, with mechanisms including cell death, immune modulation, and vascular changes. Traditional hyperthermia applications are resource-intensive and often associated with patient morbidity, limiting their clinical accessibility. Gold nanorods (GNRs) offer a precise, minimally invasive alternative by leveraging near-infrared (NIR) light to deliver targeted hyperthermia therapy (THT).
