Introduction: Patients with moderate-to-severe atopic dermatitis (AD) who are most likely to respond to the Janus kinase (JAK) 1/2 inhibitor baricitinib (BARI) are known to have an impacted body surface area (BSA) ≤ 40% and severe itch (numerical rating scale [NRS] ≥ 7], collectively termed 'BARI itch-dominant' patients. Our objective is to build on our previous work by providing a body region-specific, clinical characterization of the BARI itch-dominant patient at baseline and their response to BARI 4 mg.

Methods: BREEZE-AD7 was a phase 3 trial in adults with moderate-to-severe AD receiving placebo or 2 mg or 4 mg BARI in combination with topical corticosteroids.

Background: Obstructive shock is extremely rare in clinical practice and is caused by acute blood flow obstruction in the central vessels of either the systemic or pulmonary circulation. Utilizing inferior vena cava filters (IVCFs) to prevent pulmonary embolism (PE) is associated with some potential complications, such as inferior vena cava thrombosis (IVCT). Shock as a direct result of IVCT is rare.

Objectives: The present analyses report integrated results from BRAVE-AA1 (NCT03570749) and BRAVE-AA2 (NCT03899259) on the clinical benefits of baricitinib treatment on the basis of the amount of scalp hair regrowth through 52 weeks of treatment.

Methods: This post hoc analysis was conducted with data from patients who were treated continuously for 52 weeks with baricitinib 4 mg or 2 mg. Clinical outcomes were assessed using the Severity of Alopecia Tool (SALT) and Clinician-Reported Outcome (ClinRO) for Eyebrow (EB) and Eyelash (EL) hair.

Article Synopsis
  • Baricitinib is an approved treatment for severe alopecia areata, but there is limited understanding of how patients respond to the drug over time.
  • The study analyzed data from the BRAVE-AA1 and BRAVE-AA2 trials to identify different patterns of hair regrowth among patients taking baricitinib, categorizing them into early, gradual, and late responder subgroups based on their improvement in hair loss.
  • Results showed that a majority of patients experienced at least a 30% improvement in their SALT score by 52 weeks, with early responders achieving better outcomes more quickly compared to gradual and late responders.

Introduction: This analysis assessed association between scalp hair regrowth and improvements in health-related quality of life (HRQoL) and psychological burden in patients with severe alopecia areata (AA).

Methods: Data were pooled from two phase-3 trials ( = 1200). Patients randomized to once-daily placebo, baricitinib 2-mg, or 4-mg were analyzed independently of treatment allocation, and categorized according to scalp hair regrowth (at Week 36): meaningful regrowth (Severity of Alopecia Tool (SALT) score ≤20); intermediate regrowth (≥30% SALT improvement [SALT] at any post-baseline visit to Week 36, but SALT score > 20 at Week 36); no/minimal regrowth (never achieved SALT).

Introduction: Atopic dermatitis (AD) is a chronic, inflammatory skin disease characterized by heterogeneous clinical phenotypes and high symptom burden, especially through itch. Baricitinib (BARI), an oral Janus Kinase 1/2 inhibitor, is approved in Europe, Japan, and other countries, for treatment of adults with moderate-to-severe AD who are candidates for systemic therapy. This post hoc analysis of a Phase 3 topical corticosteroid (TCS) combination therapy trial (BREEZE-AD7) aims to characterize patients who might benefit most from BARI.

Objective: To observe the clinical efficacy of acupuncture (acupuncture for tonifying kidney and calming spirit ) in treating perimenopausal insomnia (PMI) of kidney- deficiency.

Methods: A total of 72 patients with PMI of kidney- deficiency were randomized into an observation group (36 cases, 1 case dropped off) and a control group (36 cases, 1 case dropped off). Acupuncture was applied at Baihui (GV 20) and bilateral Shenshu (BL 23), Taixi (KI 3), Anmian (Extra) in the observation group, while sham acupuncture of shallow needling at non-acupoints was applied in the control group.

Article Synopsis
  • Early prediction of therapeutic response in atopic dermatitis (AD) using baricitinib can optimize treatment strategies for patients.
  • The study identified early clinical improvements at weeks 2, 4, and 8 that could reliably predict outcomes at week 16, highlighting the importance of composite clinical scores over single parameters.
  • Results showed that improvements assessed by combinations of Eczema Area and Severity Index (EASI) and Itch Numeric Rating Scale could strongly predict later clinical response, aiding dermatologists in treatment decision-making.

Demonstrating inhibition of the structural damage to joints as a statistically significant difference in radiographic progression as measured by the van der Heijde modified Total Sharp Score (mTSS) is a common objective in trials for rheumatoid arthritis treatments. The frequently used analysis of the covariance model with missing data imputed using linear extrapolation (analyses of covariance, ANCOVA+LE) may not be ideal for long-term extension studies or for paediatric studies. The random coefficient (RC) model may represent a better alternative.

Uncovering the heterogeneity in the disease progression of Alzheimer's is a key factor to disease understanding and treatment development, so that interventions can be tailored to target the subgroups that will benefit most from the treatment, which is an important goal of precision medicine. However, in practice, one top methodological challenge hindering the heterogeneity investigation is that the true subgroup membership of each individual is often unknown. In this article, we aim to identify latent subgroups of individuals who share a common disorder progress over time, to predict latent subgroup memberships, and to estimate and infer the heterogeneous trajectories among the subgroups.
