Airway IL-1β is related to disease severity and mucociliary function in bronchiectasis.

Rationale: The inflammasome is a key regulatory complex of the inflammatory response leading to interleukin-1β (IL-1β) release and activation. IL-1β amplifies inflammatory responses and induces mucus secretion and hyperconcentration in other diseases. The role of IL-1β in bronchiectasis has not been investigated.

SFX-01 in hospitalised patients with community-acquired pneumonia during the COVID-19 pandemic: a double-blind, randomised, placebo-controlled trial.

Introduction: Sulforaphane can induce the transcription factor, Nrf2, promoting antioxidant and anti-inflammatory responses. In this study, hospitalised patients with community-acquired pneumonia (CAP) were treated with stabilised synthetic sulforaphane (SFX-01) to evaluate impact on clinical status and inflammation.

Methods: Double-blind, randomised, placebo-controlled trial of SFX-01 (300 mg oral capsule, once daily for 14 days) conducted in Dundee, UK, between November 2020 and May 2021.

Extensive acute and sustained changes to neutrophil proteomes post-SARS-CoV-2 infection.

Background: Neutrophils are important in the pathophysiology of coronavirus disease 2019 (COVID-19), but the molecular changes contributing to altered neutrophil phenotypes following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are not fully understood. We used quantitative mass spectrometry-based proteomics to explore neutrophil phenotypes immediately following acute SARS-CoV-2 infection and during recovery.

Methods: Prospective observational study of hospitalised patients with PCR-confirmed SARS-CoV-2 infection (May to December 2020).

Inflammatory Molecular Endotypes in Bronchiectasis: A European Multicenter Cohort Study.

Although inflammation and infection are key disease drivers in bronchiectasis, few studies have integrated host inflammatory and microbiome data to guide precision medicine. To identify clusters among patients with bronchiectasis on the basis of inflammatory markers and to assess the association between inflammatory endotypes, microbiome characteristics, and exacerbation risk. Patients with stable bronchiectasis were enrolled at three European centers, and cluster analysis was used to stratify the patients according to the levels of 33 sputum and serum inflammatory markers.

Dipeptidyl peptidase-1 inhibition in patients hospitalised with COVID-19: a multicentre, double-blind, randomised, parallel-group, placebo-controlled trial.

Background: Neutrophil serine proteases are involved in the pathogenesis of COVID-19 and increased serine protease activity has been reported in severe and fatal infection. We investigated whether brensocatib, an inhibitor of dipeptidyl peptidase-1 (DPP-1; an enzyme responsible for the activation of neutrophil serine proteases), would improve outcomes in patients hospitalised with COVID-19.

Methods: In a multicentre, double-blind, randomised, parallel-group, placebo-controlled trial, across 14 hospitals in the UK, patients aged 16 years and older who were hospitalised with COVID-19 and had at least one risk factor for severe disease were randomly assigned 1:1, within 96 h of hospital admission, to once-daily brensocatib 25 mg or placebo orally for 28 days.

The protective effect of SARS-CoV-2 antibodies in Scottish healthcare workers.

Background: Healthcare workers (HCWs) are believed to be at increased risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. It is not known to what extent the natural production of antibodies to SARS-CoV-2 is protective against re-infection.

Methods: A prospective observational study of HCWs in Scotland (UK) from May to September 2020 was performed.

Integrative microbiomics in bronchiectasis exacerbations.

Bronchiectasis, a progressive chronic airway disease, is characterized by microbial colonization and infection. We present an approach to the multi-biome that integrates bacterial, viral and fungal communities in bronchiectasis through weighted similarity network fusion ( https://integrative-microbiomics.ntu.

Neutrophil dysfunction in bronchiectasis: an emerging role for immunometabolism.

Bronchiectasis is a heterogenous disease with multiple underlying causes. The pathophysiology is poorly understood but neutrophilic inflammation and dysfunctional killing of pathogens is believed to be key. There are, however, no licensed therapies for bronchiectasis that directly target neutrophilic inflammation.

Comparison of the Simple Patient-Centric Atopic Dermatitis Scoring System PEST with SCORAD in Young Children Using a Ceramide Dominant Therapeutic Moisturizer.

Introduction: Patient eczema severity time (PEST) is a new atopic dermatitis (AD) scoring system based on patients' own perception of their disease. Conventional scales such as SCORing of atopic dermatitis (SCORAD) reflect the clinician's observations during the clinic visit. Instead, the PEST score captures eczema severity, relapse and recovery as experienced by the patient or caregiver on a daily basis, promoting patient engagement, compliance with treatment and improved outcomes.

Anxiety and Depression in Patients with Atopic Dermatitis in a Southeast Asian Tertiary Dermatological Centre.

Introduction: This study aimed to assess the frequency of anxiety and depression in a cohort of adult patients with atopic dermatitis (AD) in a tertiary dermatological centre, using the Hospital Anxiety and Depression Scale (HADS). We looked for any correlation between anxiety and depression with skin disease severity.

Materials And Methods: Patients with AD were recruited from the National Skin Centre, Singapore, from 2008 to 2009 for a prospective cross-sectional study.

A review on the role of moisturizers for atopic dermatitis.

Effective management of atopic dermatitis (AD) involves the treatment of a defective skin barrier. Patients with AD are therefore advised to use moisturizers regularly. To date, there are few comparative studies involving moisturizers in patients with AD, and no classification system exists to objectively determine which types of moisturizers are best suited to specific AD phenotypes.

A prospective cross-sectional study of anxiety and depression in patients with psoriasis in Singapore.

Background: Psoriasis has a negative psychological impact on patients, and may have repercussions on treatment outcomes. Despite this, the degree to which psoriatic patients suffer from psychiatric disorders has not received much attention in Singapore.

Objective: This prospective cross-sectional study was conducted to determine the frequency of anxiety and depression in a cohort of Singaporean patients with psoriasis, and explore its relationship with regards to physical disease severity and subjective quality of life.

Atopic dirty neck or acquired atopic hyperpigmentation? An epidemiological and clinical study from the National Skin Centre in Singapore.

Background: 'Atopic dirty neck' is a poorly understood acquired hyperpigmentation in patients with atopic dermatitis (AD).

Objective: To report a single-centre experience with synthesis of this entity's features.

Methods: All patients with AD with dirty neck seen over a 5-month period at the National Skin Centre were invited to participate.

Pediatric mycosis fungoides in Singapore: a series of 46 children.

Few studies have evaluated Asian children with mycosis fungoides (MF). We report a series of patients from a tertiary dermatologic institution in Singapore. A retrospective review was performed of patients younger than 16 years old diagnosed with MF between 2000 and 2008 at the National Skin Centre, Singapore.

Evaluation of a Pseudoceramide Moisturizer in Patients with Mild-to-Moderate Atopic Dermatitis.

Introduction: To evaluate the efficacy and safety of a pseudoceramide-containing moisturizer as maintenance therapy in patients with mild-to-moderate atopic dermatitis (AD).

Methods: This was a prospective, single-arm, open-label clinical trial of a twice-daily application of a pseudoceramide-containing moisturizer for 4 weeks as maintenance therapy in 40 patients with stable, mild-to-moderate AD in a tropical climate. Clinical and skin barrier assessment was done at week 0, week 2 and week 4.

Trichothiodystrophy in a child with occult learning disorder.

Trichothiodystrophy (TTD) is an autosomal recessive condition characterized by brittle and sparse sulfur deficient hair. The disorder is due to a known genetic mutation in DNA nucleotide excision repair (NER) in up to 83% of cases. We describe a 13-month-old girl presenting with hair fragility and hair loss since age 3 months, and discuss the overlap between TTD and other NER diseases.

Livedoid vasculopathy and its association with factor V Leiden mutation.

Livedoid vasculopathy is a rare chronic relapsing disorder characterised by recurrent painful thrombotic and vasculitic ulcers on the legs. We present the cases of two Indian women with livedoid vasculopathy that were found to be associated with an underlying factor V Leiden heterozygous mutation. There were no other thrombotic manifestations, and livedoid vasculopathy was the sole presenting feature of the factor V Leiden mutation, although this could also be coincidental.
