Insect protein concentrates from Mexican edible insects : structural and functional characterization

Industrial valorization of proteins from traditional edible insects requires knowledge of their nutritional, chemical, technological characteristics. Therefore, these characteristics in two Mexican edible insects (A. cordifera and B. mellifica) were studied and compared to commercial insect species (H. illucens). The nutritional attributes of insect protein concentrates (PCs) were determined by their protein content, amino acid and polyphenol compositions. The chemical structure of the proteins was determined by Fourier-Transform Infrared spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC). Moreover, the surfactant properties of insectPC (emulsions) were evaluated. B. mellifica PC showed the highest content of protein content among the studied insects (57.1%). In contrast, H. illucens showed the highest polyphenols (12.7 mg/g). The emulsions prepared with insect-PC from A. cordifera and B. mellifica showed higher stability than H. illucens, where a bigger droplet size and a rapid phase separation occurred. The decrease in emulsification properties of black soldier fly larvae was attributed to a possible interaction between polyphenols and proteins that hinders emulsification. This study increases the understanding of the structural and techno-functional characteristics of insect-PC of commercial and local insect species

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

Aims The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. Methods and results Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (inhospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, prehospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. Conclusion The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality
