55, SD= 22.16 in 2020 vs. M=3.32, SD= 6.63 in 2019) was observed. The results suggest important changes in psychiatric emergencies during the most critical period of the COVID-19 outbreak in Spain.Improving cognitive insight can reduce delusions in patients with psychotic disorders. Although institutionalized patients usually have more severe delusions than outpatients, little is known about the differences in cognitive insight between these two groups. In this study, we evaluated the psychometric properties of the Beck Cognitive Insight Scale (BCIS) for a sample of Portuguese patients with psychotic disorders and compared the cognitive insight of institutionalized patients with patients living in the community. Participants in this study were 150 patients diagnosed with psychotic disorder (78 institutionalized patients and 72 outpatients). The tested model of the BCIS was a very good fit. Our study shows that patients living in the community showed higher levels of cognitive insight (total BCIS and self-reflectiveness) than institutionalized patients. Future studies assessing cognitive insight should take into account differences between the cognitive insights of institutionalized psychotic patients and psychotic patients living in the community.Novel arylpiperazine-1,2-benzothiazine derivatives have been designed and synthesized as potential anti-inflammatory agents. Their structure and properties have been studied using spectroscopic techniques (1H NMR, 13C NMR, FT-IR), MS, elemental analyses, and single-crystal X-ray diffraction (SCXRD, for compound 7b). Histone Methyltransferase inhibitor This study aimed to evaluate the inhibitory activity of new derivatives against both cyclooxygenase isoforms COX-1 and COX-2 due to the similarity of new compounds to oxicams drugs from the NSAIDs group. All new compounds were divided into two series - A and B - with a different linker between thiazine and piperazines nitrogens. Series A included the three-carbon aliphatic linker and series B - two-carbon with a carbonyl group. According to in vitro and molecular docking studies all new compounds exhibited cyclooxygenase inhibitory activity. The series of A compounds included COX-1 inhibitors only. In contrast, the B series showed inhibition of both COX-1 and COX-2, which suggested the importance of the acetoxy linker for COX-2 inhibition. Moreover, the most selective compound 7b, towards COX-2, was non-toxic for the normal human cell line (in concentration of 10 µM) comparable to reference drug meloxicam. Additionally, investigation of influence on model membranes confirmed the ability of the compound 7b to penetrate lipid bilayers which seemed to be important to the influence with membrane protein-cyclooxygenase.
Maintenance therapy with the poly(ADP-ribose) polymerase (PARP) inhibitor olaparib provided a substantial progression-free survival (PFS) benefit compared with placebo in patients with newly diagnosed advanced ovarian cancer and a BRCA mutation (BRCAm) who were in clinical complete or partial response following platinum-based chemotherapy in the Phase III SOLO1 global study. This led to the approval of maintenance olaparib in China, USA, EU, Japan and other countries, in the newly diagnosed setting. This separate China cohort of the SOLO1 study investigated the efficacy and safety of maintenance olaparib within the Chinese population.

In this double-blind, multicentre study, patients were randomized 21 to receive oral olaparib tablets (300 mg twice daily) or placebo. The primary endpoint was investigator-assessed PFS (modified RECIST v1.1).

Of the 64 randomized patients, 44 received olaparib and 20 placebo. Olaparib reduced the risk of disease progression or death by 54% compared with placebo (HR 0.46, 95% Cl 0.23-0.97; median PFS was not reached in the olaparib arm vs 9.3 months in the placebo arm). The most common AEs in the olaparib arm were nausea (63.6 vs 25.0% with placebo), anaemia (59.1 vs 15.0%) and leukopenia (54.5 vs 20.0%). Grade ≥3 AEs were experienced by 56.8% of olaparib patients and 30.0% of placebo patients.

Results in the SOLO1 China cohort support the use of olaparib as maintenance treatment for Chinese patients with newly diagnosed advanced ovarian cancer who have a BRCAm and are in complete or partial response after platinum-based chemotherapy.

The optimal substrate for hypothermic machine perfusion preservation of donor hearts is unknown. Fatty acids, acetate, and ketones are preferred substrates of the heart during normothermic perfusion, but cannot replete the tricarboxylic acid (TCA) cycle directly. Propionate, an anaplerotic substrate, can replenish TCA cycle intermediates and may affect cardiac metabolism. The purpose of this study was to determine myocardial substrate preferences during hypothermic machine perfusion and to assess if an anaplerotic substrate was required to maintain the TCA cycle intermediate pool in perfused hearts.

Groups of rat hearts were perfused with carbon-13 (
C)-labeled substrates (acetate, β-hydroxybutyrate, octanoate, with and without propionate) at low and high concentrations. TCA cycle intermediate concentrations, substrate selection, and TCA cycle flux were determined by gas chromatography/mass spectroscopy and
C magnetic resonance spectroscopy.

Acetate and octanoate were preferentially oxidized, whereas β-hydroxybutyrate was a minor substrate. TCA cycle intermediate concentrations except fumarate were higher in substrate-containing perfusion groups compared with either the no-substrate perfusion group or the no-ischemia control group.

The presence of an exogenous, oxidizable substrate is required to support metabolism in the cold perfused heart. An anaplerotic substrate is not essential to maintain the TCA cycle intermediate pool and support oxidative metabolism under these conditions.
