Background: Hymenoptera stings can cause systemic allergic reactions (SARs) that are prevented by venom immunotherapy (VIT). Sting challenge tests or field stings are used to evaluate the outcome of VIT.
Objective: The aim of the study was to investigate the consequences of field stings in patients during or after completion of VIT, and to identify patients at higher risk.
Methods: Patients treated with VIT between 1995 and 2018 were retrospectively evaluated. Contacted patients were invited to the clinic and a questionnaire was conducted regarding the history of field stings.
Results: A total of 115 patients (F/M: 45/70, mean age: 38.5 ± 12 years) treated with VIT were included; 74/115 were contacted and asked about field stings after VIT cessation. A history of 73 field stings was reported in 38 patients, 25 of whom were treated with honeybee venom and 13 with common wasp venom. Eighteen of the reactions were SARs [8 with honeybees (1 grade-I, 6 grade-II, 1 grade-III) and 10 with common wasps (1 grade-I, 5 grade-II, 4 grade-III)]. There was no association between the severity of index reactions and field stings with either the honeybee or common wasp. The median duration of VIT was longer in patients showing no reaction than in patients with an SAR. Of the 7 patients on ACE inhibitors or beta-blockers, 1 asthmatic patient developed grade-II SAR due to field stings in the first year of VIT.
Conclusions: This study confirms that VIT lasting at least 3 years is effective in preventing SARs after field stings.

Background: The evaluation and management of insect sting allergy is a complex core competency taught in Allergy and Immunology fellowship programs. It is unclear if current training on insect allergy is sufficient to meet the needs of the field, and what training barriers exist.
Objective: To investigate the extent of training on stinging insect allergy, and factors currently impacting stinging insect allergy clinical practice through a pilot needs-assessment survey.

Rabies is a viral zoonosis that kills thousands of people annually in low- and middle-income countries across Africa and Asia where domestic dogs are the reservoir. 'Zero by 30', the global strategy to end dog-mediated human rabies, promotes a One Health approach underpinned by mass dog vaccination, post-exposure vaccination of bite victims, robust surveillance and community engagement. Using Integrated Bite Case Management (IBCM) and whole genome sequencing (WGS), we enhanced rabies surveillance to detect an outbreak in a formerly rabies-free island province in the Philippines.

Objectives: To investigate the role of mitochondrial autophagy disorder caused by deletion of E3 ubiquitin ligase Parkin in neuroinflammation in a mouse model of MPTP-induced Parkinson's disease (PD).
Methods: Wild-type (WT) male C57BL/6 mice and Parkin mice were given intraperitoneal injections with MPTP or PBS for 5 consecutive days, and the changes in motor behaviors of the mice were observed using open field test. The effects of Parkin deletion on PD development and neuroinflammation were evaluated using immunofluorescence and Western blotting.

Introduction And Methods: Aiming to evaluate safety aspects of a recently proposed approach to target Alzheimer's disease, we mimicked a complex boron neutron capture therapy field using a mixed beam consisting of high- and low-linear energy transfer (LET) radiation, Am alpha particles (α) and/or X-ray radiation respectively, in human microglial (HMC3) cells.
Results: Acute exposure to 2 Gy X-rays induced the strongest response in the formation of γH2AX foci 30 min post irradiation, while α- and mixed beam-induced damage (α:X-ray = 3:1) sustained longer. Fractionation of the same total dose (0.
Nanomedicines harnessing cGAS-STING pathway: sparking immune revitalization to transform 'cold' tumors into 'hot' tumors.

cGAS-STING pathway stands at the forefront of innate immunity and plays a critical role in regulating adaptive immune responses, making it as a key orchestrator of anti-tumor immunity. Despite the great potential, clinical outcomes with cGAS-STING activators have been disappointing due to their unfavorable in vivo fate, signaling an urgent need for innovative solutions to bridge the gap in clinical translation. Recent advancements in nanotechnology have propelled cGAS-STING-targeting nanomedicines to the cutting-edge of cancer therapy, leveraging precise drug delivery systems and multifunctional platforms to achieve remarkable region-specific biodistribution and potent therapeutic efficacy.
