Red-Fleshed Apples Rich in Anthocyanins and White-Fleshed Apples Modulate the Aorta and Heart Proteome in Hypercholesterolaemic Rats: The AppleCOR Study

The impact of a red-fleshed apple (RFA) rich in anthocyanins (ACNs), a white-fleshed apple (WFA) without ACNs, and an extract infusion from Aronia fruit (AI) equivalent in dose of cyanidin-3-O-galactoside (main ACN) as RFA was determined by the proteome profile of aorta and heart as key cardiovascular tissues. Hypercholesterolaemic Wistar rats were separated into six groups (n = 6/group; three males and three females) and the proteomic profiles were analyzed using nanoliquid chromatography coupled to mass spectrometry. No adverse events were reported and all products were well tolerated. RFA downregulated C1QB and CFP in aorta and CRP in heart. WFA downregulated C1QB and CFP in aorta and C9 and C3 in aorta and heart, among other proteins. AI downregulated PRKACA, IQGAP1, and HSP90AB1 related to cellular signaling. Thus, both apples showed an anti-inflammatory effect through the complement system, while RFA reduced CRP. Regardless of the ACN content, an apple matrix effect was observed that involved different bioactive components, and inflammatory proteins were reduced.     

Inhibition of the BMP Signaling Pathway Ameliorated Established Clinical Symptoms of Experimental Autoimmune Encephalomyelitis

Bone morphogenetic proteins (BMPs) are secreted growth factors that belong to the transforming growth factor beta superfamily. BMPs have been implicated in physiological processes, but they are also involved in many pathological conditions. Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system (CNS); however, its etiology remains elusive. Some evidence points to BMPs as important players in the pathogenesis of inflammatory and autoimmune disorders. In the present work, we studied the expression of BMP2, BMP4, BMP5, BMP6, BMP7, BMP type II receptor, and noggin in the immune system during different phases of experimental autoimmune encephalomyelitis (EAE). Major changes in the expression of BMPs took place in the initial phases of EAE. Indeed, those changes mainly affected BMP6 (whose expression was abrogated), BMP2, and BMP7 (whose expression was increased). In addition, we showed that in vivo inhibition of the BMP signaling pathway with small molecules ameliorated the already established clinical symptoms of EAE, as well as the CNS histopathological features. At the immune level, we observed an expansion of plasmacytoid dendritic cells (pDCs) in mice treated with small molecules that inhibit the BMP signaling pathway. pDCs could play an important role in promoting the expansion of antigen-specific regulatory T cells. Altogether, our data suggest a role for BMPs in early immune events that take place in myelin oligodendrocyte glycoprotein (MOG)-induced EAE. In addition, the clinical outcome of the disease was improved when the BMP signaling pathway was inhibited in mice that presented established EAE symptoms.Electronic supplementary materialThe online version of this article (10.1007/s13311-020-00885-8) contains supplementary material, which is available to authorized users.     

Endoscopic Treatment of Persistent Alveolar-Pleural Air Leaks With a Unidirectional Endobronchial Valve

The persistent air leaks due to alveolopleural fistula is not an uncommon complication of pneumothorax, particularly secondary ones. Unidirectional flow endobronchial valves initially designed for lung volume reduction are the latest tool in the therapeutic armamentarium.We present a patient with chronic obstructive pulmonary disease (COPD) with a persistent pneumothorax in spite of three pleurodesis, which was able to be resolved with the placement of two IBV? valves.     

Socioeconomic Inequalities in Unintended Pregnancy and Abortion Decision

Pregnancy planning allows women to better control their life trajectory and contributes to the future child’s health and development. Many studies that have analyzed socioeconomic inequalities in unintended pregnancy only took into account those pregnancies ending in births. Few of them that analyzed unintended pregnancy, including both induced abortion and births, and its socioeconomic determinants, concluded that unintended pregnancy is more frequent in young, poor, or unmarried women. These inequalities have been poorly studied in Europe, especially in the southern European context. The aim of the present study is to describe socioeconomic inequalities in unintended pregnancy and in abortion decision in Barcelona, Spain. The major findings are that unintended pregnancies accounted for 41% of total pregnancy and of these, 60% ended in abortion. From all pregnancies, the proportion of induced abortion reached 25.6%. Compared to women with university studies, those with primary education uncompleted had more unintended pregnancies (OR = 7.22). When facing an unintended pregnancy, women of lower socioeconomic position are more likely to choose induced abortion, although this is not the case among young or single women. This study reveals deep socioeconomic inequalities in unintended pregnancies and abortion decision in Barcelona, Spain, where the birth rate is very low and the abortion rate is rising. Women in low socioeconomic positions have many more unintended pregnancies than better educated women. Except for young or single women, the lower the socioeconomic position, the higher the proportion of women who choose an induced abortion when facing an unintended pregnancy.

Parahippocampal gray matter density in panic disorder: a voxel-based morphometric study

OBJECTIVE: The authors examined possible cerebral gray matter abnormalities in patients with panic disorder. METHOD: Gray matter concentration in 18 panic disorder outpatients and 18 healthy subjects was compared by using a voxel-based morphometry approach. RESULTS: Gray matter density of the left parahippocampal gyrus was significantly lower in patients with panic disorder compared with healthy subjects. CONCLUSIONS: This result provides further support for the involvement of the parahippocampal area in the pathophysiology of panic disorder.
