We report a unique case of a 67-year-old man with a typical carcinoid of the middle mediastinum that adhered tightly to the pericardium, the posterior part of the ascending aorta and the pulmonary trunk, that was radically resected with the patient on cardiopulmonary bypass by clamping, sectioning and suturing the ascending aorta.
In Africa, antipsychotic polypharmacy is growing high due to a high antipsychotic dose prescribing, repeated psychiatric hospitalization, uncontrolled psychotic symptoms, and greater side effect burden. Therefore, the aim of this review and meta-analysis is to assess the prevalence and correlates of antipsychotic polypharmacy among patients with schizophrenia in Africa.

A systematic search was performed from August 1 to 31, 2020 on PubMed, MEDLINE, Google Scholar and Science Direct databases to select articles based on the inclusion criteria. learn more Meta-Analysis of Observational studies in Epidemiology (MOOSE) guidelines were employed. Cross-sectional observational studies which report antipsychotic polypharmacy and/or its correlates in schizophrenia patients in English language published in a peer reviewed journals without time limits were included in the review.The quality of included articles was assessed using Newcastle-Ottawa quality assessment tool. Prevalence and correlates of antipsychotic polypharmacy d and reported.

Antipsychotic polypharmacy is common and highly prevalent. Advanced age, male gender, longer duration of schizophrenia, hospital admission and longer antipsychotic treatment were correlates of antipsychotic polypharmacy in Africa.

Owing to the increased risk of colorectal cancer (CRC) in patients with inflammatory bowel disease (IBD), numerous societies developed preventative guidelines. We aimed to assess the overall quality of CRC prevention guidelines in IBD.

A systematic search was performed in multiple databases to identify all guidelines pertaining to CRC prevention in IBD in September 2020. All guidelines were reviewed for conflicts of interest (COIs)/funding, recommendation quality/strength, external guideline review, use of patient representation, and plans for update-as per Institute of Medicine standards. In addition, recommendations were compared amongst societies.

One hundred forty-nine recommendations from 14 different guidelines/societies were included. Not all guidelines provided recommendations on key elements surrounding (1) screening initiation and surveillance, (2) screening modality, (3) pharmacological chemoprevention, (4) dysplasia management and follow-up, and (5) molecular marker use. Only 71% of guidelined to improve the overall quality of evidence.The Polysaccharide Lyase Family 6 (PL6) represents one of the 41 polysaccharide lyase families classified in the CAZy database with the vast majority of its members being alginate lyases grouped into three subfamilies, PL6_1-3. To decipher the mode of recognition and action of the enzymes belonging to subfamily PL6_1, we solved the crystal structures of Pedsa0632, Patl3640, Pedsa3628 and Pedsa3807, which all show different substrate specificities and mode of action (endo-/exo-lyase). Thorough exploration of the structures of Pedsa0632 and Patl3640 in complex with their substrates as well as docking experiments confirm that the conserved residues in subsites -1 to +3 of the catalytic site form a common platform which can accommodate various types of alginate in a very similar manner but with a series of original adaptations bringing them their specificities of action. From comparative studies with existing structures of PL6_1 alginate lyases, we observe that in the right-handed parallel β-helix fold shared by all these enzymes, the substrate binding site harbors the same overall conserved structures and organization. Despite this apparent similarity, it appears that members of the PL6_1 subfamily specifically accommodate and catalyze the degradation of different alginates suggesting that this common platform is actually a highly adaptable and specific tool.Glioblastoma (GB) is the most aggressive and common form of primary brain tumor characterized by fast proliferation, high invasion, and resistance to current standard treatment. The average survival rate post-diagnosis is 14.6 months, despite the aggressive standard post-surgery radiotherapy concomitant with chemotherapy with temozolomide (TMZ). Currently, efforts are being endowed to develop new and more efficient therapeutic approaches capable to overcome chemoresistance, inhibit tumor progression and improve overall patient survival rate. Abnormal microRNA (miRNA) expression has been correlated with chemoresistance, proliferation and resistance to apoptosis, which result from their master regulatory role of gene expression. Altered cell metabolism, favoring glycolysis, was identified as an emerging cancer hallmark and has been described in GB, thus offering a new target for innovative GB therapies. In this work, we hypothesized that a gene therapy-based strategy consisting of the overexpression of a miRNA downregulated in GB and predicted to target crucial metabolic enzymes might promote a shift of GB cell metabolism, decreasing the glycolytic dependence of tumor cells and contributing to their sensitization to chemotherapy with TMZ. The increase of miR-200c levels in DBTRG cells resulted in downregulation of mRNA of enzymes involved in bioenergetics pathways and impaired cell metabolism and mobility. Additionally, miR-200c overexpression prior to DBTRG cell exposure to TMZ resulted in cell cycle arrest. Overall, our results show that miR-200c overexpression could offer a way to overcome chemoresistance developed by GB cells in response to current standard chemotherapy, providing an improvement to current GB standard treatment, with benefit for patient outcome.
Intrauterine growth restriction (IUGR) is an immediate outcome of an adverse womb environment, exposing newborns to developing cardiometabolic disorders later in life. This study investigates the cardiac metabolic consequences and underlying mechanism of energy expenditure in developing fetuses under conditions of IUGR.

Using an animal model of IUGR characterized by uteroplacental vascular insufficiency, mitochondrial function, gene profiling, lipidomic analysis, and transcriptional assay were determined in fetal cardiac tissue and cardiomyocytes.

IUGR fetuses exhibited an upregulation of key genes associated with fatty acid breakdown and β-oxidation (Acadvl, Acadl, Acaa2), and mitochondrial carnitine shuttle (Cpt1a, Cpt2), instigating a metabolic gene reprogramming in the heart. Induction of Ech1, Acox1, Acox3, Acsl1, and Pex11a indicated a coordinated interplay with peroxisomal β-oxidation and biogenesis mainly observed in females, suggesting sexual dimorphism in peroxisomal activation. Concurring with the sex-related changes, mitochondrial respiration rates were stronger in IUGR female fetal cardiomyocytes, accounting for enhanced ATP production.
