Authors: Aubry A, Paternot A, Vieillard-Baron A Abstract Cor pulmonale is a disease of the heart characterised by dilatation of the right ventricle and paradoxical movement of the interventricular septum. The diagnosis depends on echocardiography even if pulmonary artery catheterisation suggests it. It is secondary to pulmonary disease or a disorder of the pulmonary circulation. These two mechanisms, which are often connected, involve pulmonary hypertension as the origin of a systolic and diastolic overload of the right ventricle, which then leads to the alterations of its structure and performance. Acute cor pulmo...

CONCLUSIONS: Our findings support the use of omalizumab in selected forms of EGPA, but caution in the tapering of corticosteroids is also recommended. Quality of evidence is limited, as the source of information was mainly case reports. Clinical trials are required in order to evaluate the role of omalizumab in EGPA and to ascertain the risk of asthmatic patients given omalizumab to develop EGPA.

This study aimed to determine serum total IgE level, eosinophil count, and serum level of IFN-γ, in relation to the age of atopic patients and genotyping of the IFN-γ gene at +874 T/A in relation to serum IFN-γ level. As well as comparing of IFN-γ concentrations of atopic patients according to genotypes in atopic patients and apparently healthy control. The studied groups were 25 apparently healthy controls and 75 atopic patients (25 asthma patients, 25 allergic rhinitis patients and 25 atopic dermatitis patients). The obtained results showed that, the prevalence of atopic diseases occurred in the...

ConclusionsThese findings suggest that glycopyrronium, formoterol, and a combination of glycopyrronium, formoterol, and budesonide inhibit HCoV-229E replication partly by inhibiting receptor expression and/or endosomal function and that these drugs modulate infection-induced inflammation in the airway.

Every year in the United States, the CDC estimates that influenza results in between 9 million – 45 million illnesses, between 140,000 – 810,000 hospitalizations, and between 12,000 – 61,000 deaths (approximately 100  – 200 being pediatric fatalities). In the United States, the immense disease burden of the flu is unparalleled with any other pathogen, but fortunately there is a vaccine and antiviral medications which help to mitigate the yearly morbidity and mortality wrought by influenza.Because the flu changes its shape every year by a process called antigenic shift&n...

ConclusionsThis large observational study based on claims data reliably identified subjects with COPD treated with open TT and their burden on the NHS. Moreover, it could describe the real clinical management of the open TT, before the marketing of the fixed one. These findings are useful for health policymakers in order to promote the appropriate utilization of both currently marketed and future therapies.

Whether there are specific clinical and pathophysiological features can indicate RB in patients with CVA needs further investigation. Thus, we aimed to investigate the RB in patients with CVA and associated factors.MethodsForty-two CVA patients were randomized in a 2:1 ratio to receive oral bambuterol hydrochl...
