Allergic rhinitis (AR) is a common disorder that is strongly linked to asthma and conjunctivitis. Classic symptoms include nasal congestion, nasal itch, rhinorrhea and sneezing. A thorough history, physical examination and assessment of allergen sensitization are important for establishing the diagnosis of AR.

Syngnathidae are a charismatic family of teleost fishes, represented by seahorses, seadragons, and pipefishes. Syngnathidae are mainly composed of marine species, but about 30 species of pipefishes inhabit freshwater insular environments of the Indo-Pacific realm. Recent research has shown that some freshwater pipefish species are amphidromous and exhibit high intraspecific divergences across their distribution range, like Microphis brachyurus (Bleeker, 1854) distributed from Sri Lanka to French Polynesia and Microphis retzii (Bleeker, 1856) distributed from Taiwan to Indonesia.

Article Synopsis
  • Hereditary angioedema (HAE) is a chronic disease requiring effective long-term preventive treatments, prompting a study to evaluate the safety and efficacy of garadacimab, a new medication for HAE.
  • In an interim analysis of the ongoing phase 3 VANGUARD study, involving 161 patients, most treatment-emergent adverse events (TEAEs) were mild, with injection-site reactions being the most common, and no serious complications linked to garadacimab were reported.
  • The results showed a significant reduction in HAE attacks, with 60% of patients remaining attack-free, indicating that garadacimab offers a safe and effective long-term treatment option for patients with

Article Synopsis
  • Primary immunodeficiency diseases (PIDs) are genetic immune system disorders requiring lifelong immunoglobulin replacement therapy, usually delivered through IVIG or SCIG infusions.
  • Ig20Gly, a 20% immune globulin solution, is a replacement therapy approved for various age groups, with recent approvals for manual administration in Europe aimed at simplifying the process.
  • Manual administration of Ig20Gly allows for faster infusion rates, similar safety and satisfaction levels compared to infusion pumps, and potential cost savings for healthcare systems due to lower equipment and nursing needs.

Allergic rhinitis (AR) is a prevalent disease in Canada that affects both children and adults. Several guidelines for the management of AR have been published by professional allergy societies worldwide. However, there are regional differences in the clinical management of AR, and regulatory approval of some AR pharmacotherapies varies among countries.

Background: Garadacimab is a fully human immunoglobulin G4 monoclonal antibody targeting activated factor XII. This study evaluated long-term efficacy, health-related quality of life (HRQoL), and safety data for garadacimab in adults with hereditary angioedema.

Methods: This global phase 2 study comprised a treatment period 1 (TP1: 12 weeks, double-blind, placebo-controlled) and a treatment period 2 (TP2: ≥44-week open-label extension).

Background: Throughout the COVID-19 pandemic, the mortality of critically ill patients remained high. Our group developed a treatment regimen targeting sepsis and ARDS which we labeled "triple therapy" consisting of (1) corticosteroids, (2) therapeutic plasma exchange (TPE), and (3) timely intubation with lung protective ventilation. Our propensity analysis assesses the impact of triple therapy on survival in COVID-19 patients with sepsis and ARDS.

Insular biodiversity hotspots of Southeast Asia are remarkable for their biodiverse faunas. With a marine larval phase lasting up to several months, the freshwater fish subfamily Sicydiinae has colonized most islands of these hotspots. However, Sicydiinae diversity is still poorly understood in Southeast Asia.

Article Synopsis
  • The study investigates the effects of therapeutic plasma exchange (TPE) on short-term mortality for adults with sepsis-induced organ dysfunction, highlighting the uncertainty of its impact.
  • A thorough literature review was conducted, analyzing randomized clinical trials and matched cohort studies to compare mortality rates between patients receiving standard therapy and those receiving adjunct TPE.
  • The findings indicate that incorporating TPE into standard care may significantly reduce short-term mortality and lead to quicker recovery for critically ill septic patients.

Background: Similar immune responses in the nasal and bronchial mucosa implies that nasal allergen challenge (NAC) is a suitable early phase experimental model for drug development targeting allergic rhinitis (AR) and asthma. We assessed NAC reproducibility and the effects of intranasal corticosteroids (INCS) on symptoms, physiology, and inflammatory mediators.

Methods: 20 participants with mild atopic asthma and AR underwent three single blinded nasal challenges each separated by three weeks (NCT03431961).

Article Synopsis
  • * Researchers identified a new host and infection site for this parasite in the gills of the cleft-lipped goby from Ranongga Island.
  • * This is the first record of this specific species of digenean parasite in Indo-Pacific fish and marks its first appearance in the Solomon Islands, supported by phylogenetic analysis.

Background: Hereditary angioedema (HAE) is a rare disease characterized by unpredictable, recurring subcutaneous or submucosal swelling. Without effective therapy, HAE can negatively impact patients' quality of life. Management of HAE includes on-demand treatment of attacks and short- and long-term prophylaxis (LTP) to prevent attacks.

Background: Chronic rhinosinusitis with nasal polyposis (CRSwNP) often coexists with lower airway disease. With the overlap between upper and lower airway disease, optimal management of the upper airways is undertaken in conjunction with that of the lower airways. Biologic therapy with targeted activity within the Type 2 inflammatory pathway can improve the clinical signs and symptoms of both upper and lower airway diseases.

Article Synopsis
  • Scientists analyze otoliths, small ear-like structures in fish, to study their life history and migration patterns, which often contain growth and environmental signatures.
  • Using synchrotron-based scanning X-ray fluorescence, researchers can create detailed maps of element distribution in these otoliths, revealing important migration and growth information that was previously unclear, especially in fragile species like the freshwater pipefish.
  • A significant finding includes the confirmation that certain tropical pipefish are diadromous and the innovative use of sulfur signals allows for accurate age estimation and growth increment analysis, enhancing the understanding of fish life traits and conservation efforts.

Sicyopterus garra Hora, 1925 from the insular streams of South Andaman Islands was synonymized with Sicyopterus microcephalus described from Java, South East Asia and has retained this taxonomic status since then. Recent collections of Sicyopterus from the type locality of S. garra and the examination of syntypes of this species revealed significant morphological and genetic differences from S.

Background: Real-world data on transitioning to Immune Globulin Subcutaneous (Human) 20% solution (Ig20Gly) are limited. This study aimed to assess infusion parameters and experience of patients with primary (PID) or secondary immunodeficiencies (SID) transitioning to Ig20Gly in clinical practice in Canada.

Methods: Patients with PID or SID who received subcutaneous immunoglobulin (SCIG) for ≥ 3 months before transitioning to Ig20Gly were eligible for this multicenter (n = 6), phase 4, non-interventional, prospective, single-arm study.

Background: Opioid induced chest wall rigidity was first described in the early 1950s during surgical anesthesia and has often been referred to as fentanyl induced rigid chest syndrome (FIRCS). It has most commonly been described in the setting of procedural sedation and bronchoscopy, characterized by pronounced abdominal and thoracic rigidity, asynchronous ventilation, and respiratory failure. FIRCS has been infrequently described in the setting of continuous analgesia in critically ill adult patients.
