Insect-based fish feed in decoupled aquaponic systems: Effect on lettuce production and resource use.

The utilisation of insect meal-based fish feed as a substitute for conventional fish meal-based fish feed is considered as a promising innovative alternative to boost circularity in aquaculture and aquaponics. Basic research on its use in aquaponics is limited. So far, no reports on the effects of fish waste water, derived from a recirculating aquaculture system using Black Soldier Fly (BSF) meal-based diets, were available on the growth performance of lettuce.

Light chain cardiac amyloidosis - a rare cause of heart failure in a young adult.

Cardiac amyloidosis is an infiltrative cardiomyopathy, resulting from amyloid deposition within the myocardium. In primary systemic (AL-type) amyloidosis, the amyloid protein is composed of light chains resulting from plasma-cell dyscrasia, and cardiac involvement occurs in up to 50% of the patients We present a case of a 43-year-old man, with complaints of periodical swollen tongue and xerostomia, bleeding gums and haematuria for two months. His blood results showed normocytic anaemia, thrombocytopenia and a high spontaneous INR, therefore he was referred to the Internal Medicine clinic.

Coronary angiography after successful thrombolysis - Is the recommended time interval of 24h an important issue?

Introduction: Percutaneous coronary intervention (PCI) is currently considered the gold-standard treatment of acute coronary syndromes with ST-segment elevation (STEMI). However, this is not the reality of many European centers, where thrombolysis is performed as primary therapy.

Aims: To determine, in a STEMI population that performed successful fibrinolytic treatment, if the performance of coronary angiography after the first 24h was associated with more hospital complications, including higher mortality, compared with its performance in the recommended time.

Native aortic valve pneumococcal endocarditis--fulminant presentation.

Pneumococcal endocarditis is a rare entity, corresponding to 1 to 3% of native valve endocarditis cases. It has a typically adverse prognosis, with high mortality. There is a reported predilection for the aortic valve; thus, a common presentation is acute left heart failure.

Primary cardiac lymphoma in a patient with concomitant renal cancer.

Primary cardiac lymphoma is defined as non-Hodgkin lymphoma involving the heart and/or pericardium. It is a rare cancer that primarily affects the right heart and in particular the right atrium. By contrast, renal cell carcinoma is a relatively common cancer, which in rare circumstances can metastasize to the heart.

A case of rheumatic valvular heart disease and autoimmune gastritis.

We present a case of a 50-year-old female patient with a history of depressive disorder and anaemia (attributed to menorrhagias). She was admitted to the cardiology department with symptoms of fatigue on moderate exertion for several months, with worsening in the month before hospitalisation. Echocardiography revealed a severe mitral stenosis of rheumatic aetiology.

Effusive-constrictive pericarditis as the manifestation of an unexpected diagnosis.

Constrictive pericarditis is a clinical condition characterized by the appearance of signs and symptoms of right heart failure due to loss of pericardial compliance. Cardiac surgery is now one of the most frequent causes in developed countries, while tuberculosis remains the most prevalent cause in developing countries. Malignancy is a rare cause but usually has a poor prognosis.

Obstructive sleep apnea syndrome: An important piece in the puzzle of cardiovascular risk factors.

The obstructive sleep apnea syndrome (OSA) is a clinical entity characterized by recurring episodes of apnea and/or hypopnea during sleep, due to a total or partial collapse, respectively, of the upper airway. This collapse originates a set of pathophysiological changes that determine the appearance of several cardiovascular complications. OSA contributes for the development of hypertension, heart failure, arrhythmias and coronary heart disease.

A systemic disease un…suspected by physical examination.

A 73-year-old man was admitted to the cardiology department with unstable angina. He had a history of macroglossia with 3 years of development, attributed to hypothyroidism. On physical examination, he presented an exuberant macroglossia.

Elevated factor VIII in a patient with acute coronary syndrome.

Factor VIII is a clotting factor that plays a crucial role in the coagulation cascade. Above-normal levels are found in 11% of the general adult population. Various studies have established a causal association between elevated factor VIII and venous thrombosis; some studies also suggest a relation with arterial thrombosis, particularly myocardial infarction and stroke.

Myocardial infarction as the first probable manifestation of caseous calcification of the mitral annulus.

Calcification of the mitral annulus is a common echocardiographic finding during routine evaluation of patients. Caseous calcification of the mitral annulus (CCMA) on the other hand is a rare variant, occurring in about 0.06-0.
