Severe pulmonary arterial hypertension and cardiogenic shock in acute systemic lupus erythematosus.

We describe a woman in her late 20s with newly diagnosed systemic lupus erythematosus (SLE), who presented with fulminant pulmonary arterial hypertension (PAH) requiring inotropic and extracorporeal support. She was established on triple pulmonary vasodilator therapy with concurrent aggressive immunosuppression; however, treatment was complicated by infection and diffuse alveolar haemorrhage, necessitating delays in immunosuppression and withdrawal of epoprostenol. Despite this, with ongoing suppression of her SLE, her pulmonary haemodynamics improved, with normal pressures on right heart catheterisation several months later allowing stepdown to sildenafil monotherapy.

The multi-target directed ligands (MTDLs) strategy has been evolved as the propitious approach for the development of therapeutics for Alzheimer's disease (AD). In an earlier report, we described the novel series of chalcone derivatives bearing N-aryl piperazine scaffold as MTDLs for the treatment of AD. Herein, we report the lead optimization of the series culminating in potent, multi-targeting compounds (32-57), evaluated through in-vitro and in-vivo biological studies.

Several interventional strategies have been implemented in malaria endemic areas where the burden is high, that include among others, intermittent preventive treatment (IPT), a tactic that blocks transmission and can reduce disease morbidity. However, the implementation IPT strategies raises a genuine concern, intervening the development of naturally acquired immunity to malaria which requires continuous contact with parasite antigens. This study investigated whether dihydroartemisinin-piperaquine (DP) or artesunate-amodiaquine (ASAQ) IPT in schoolchildren (IPTsc) impairs IgG reactivity to six malaria antigens.

Division of Endocrinology, Santiago de Compostela University and Ciber OBN, Santiago, Spain.
Purpose: A recent update of consensus guidelines for the management of Cushing's disease (CD) included indications for medical therapy. However, there is limited evidence regarding their implementation in clinical practice. This study aimed to evaluate current medical therapy approaches by expert pituitary centers through an audit conducted to validate the criteria of Pituitary Tumors Centers of Excellence (PTCOEs) and provide an initial standard of medical care for CD.

Background: CDK4/6 inhibitors have significantly improved the survival of patients with HR-positive/HER2-negative breast cancer, becoming a first-line treatment option. However, the development of resistance to these inhibitors is inevitable. To address this challenge, novel strategies are required to overcome resistance, necessitating a deeper understanding of its mechanisms.
