Xia Li, Xuan Tang, Jinping Lu, Sheng Yuan
Galectin-3 is an important mediator of cardiac fibrosis and heart failure. Cell viability of cardiomyocytes was measured using a CCK‑8 assay; flow cytometry was employed for the detection of the cell cycle and cardiomyocytes apoptosis. Reverse transcription‑quantitative polymerase chain reaction and western blotting was performed to examine the expression of associated genes and proteins. The present study demonstrated that overexpression of galectin‑3 significantly decreased the viability of cardiomyocytes in a time‑dependent manner, with simultaneous arrest of the cell cycle and induction of apoptosis...

The cardiotoxicity of chemotherapy (CTx) for non-Hodgkin's lymphomas is not well recognized. In order to facilitate individual risk counseling for patients, we analyzed the effect of CTx on echocardiographic indices in regard to clinical data in patients treated for non-Hodgkin's lymphoma (NHL). A prospective multicenter ONCO-ECHO trial included 67 patients with NHL (45 patients with DLBCL (diffuse large B cell lymphoma) and 22 with non-DLBCL). Patients received standard CTx, primarily R-CHOP, CHOP, R-COP and COP regimens...

The phosphatidylinositol 3-kinase (PI3K) pathway has attracted immense interest as a therapeutic target for cancer treatment. Idelalisib was the first PI3K inhibitor approved by the US Food and Drug Administration and is utilized in the treatment of relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma and follicular lymphoma. Copanlisib has subsequently been approved for relapsed follicular lymphoma in patients who have received at least two prior systemic therapies. There are multiple other PI3K agents currently in development; these target various combinations of PI3K isoforms...

BACKGROUND AND PURPOSE: Focal cortical infarction causes neuronal apoptosis in the ipsilateral nonischemic thalamus and hippocampus, which is potentially associated with poststroke cognitive deficits. TSPO (translocator protein) is critical in regulating mitochondrial apoptosis pathways. We examined the effects of the novel TSPO ligand 2-(2-chlorophenyl) quinazolin-4-yl dimethylcarbamate (2-Cl-MGV-1) on poststroke cognitive deficits, neuronal mitochondrial apoptosis, and secondary damage in the ipsilateral thalamus and hippocampus after cortical infarction...

Over the period 2010-2012, maternal mortality linked to anesthesia accounted for 2% of maternal deaths, with no significant change since 2007-2009. Of the 7 maternal deaths analyzed by the expert committee, anesthetic complications were in 5 cases the main cause of death: 4 attributed to direct causes related to anesthetic procedures during childbirth and 1 to indirect cause in connection with an ENT complication during pregnancy. The anesthetic causes of maternal mortality were for the 2010-2012 period: cardiac arrest under spinal anesthesia during caesarean section, local anesthetic intoxication with unsuccessful resuscitation after cardiac arrest without intralipid administration, acute respiratory distress syndrome in the postpartum period after pulmonary aspiration during caesarean section, cardiac arrest during caesarean section under general anesthesia in a context of non-Hodgkin lymphoma with mediastinal syndrome, unsuccessful endotracheal intubation in a context of cellulitis of the oral cavity floor...

Renal inflammation contributes to the pathogeneses of hypertension. This study was designed to determine whether B-cell lymphoma 6 (BCL6) attenuates renal NLRP3 inflammasome activation and inflammation and its underlying mechanism. Male spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY) were used in the present study. Angiotensin (Ang) II or lipopolysaccharides (LPS) was used to induce inflammation in HK-2 cells, a human renal tubular epithelial (RTE) cell line. NLRP3 inflammasome was activated and BCL6 was downregulated in the kidneys of SHR...

Preeclampsia (PE) is one of the most common pregnancy-specific pathologic complications, and is characterised by onset of hypertension and proteinuria. Placental trophoblast cell apoptosis is generally accepted as a major cause of PE. However, the details of the mechanism underlying the condition remain unclear. Here, we aimed to investigate a possible association between microRNA (miR)-34a and human trophoblast cell apoptosis during PE. We evaluated miR-34a expression in placentas from patients with PE compared with those from healthy pregnant individuals...

Among 42 consecutive patients with malignant lymphoma who underwent high-dose chemotherapy (HDC) followed by autologous hematopoietic stem cell transplantation (AHSCT), 5 developed hemolytic anemia with fragmented red blood cells (HA-FrRBCs) on days 87-125 (median 107) of AHSCT. Nadir Hb levels ranged between 5.0 and 6.4 g/dL with 2.2-5.6% FrRBCs. All patients developed grade ≥3 hypoxia and heart failure, and 4 developed grade ≥3 hypertension. The ejection fraction of the left ventricle assessed by echocardiography was significantly reduced in 3 patients...

PURPOSE: Dermatomyositis (DM) represents an auto-immune inflammatory myopathy. In this review, we analyzed the incidence of DM as a clinical manifestation highlighting the peculiar clinical and treatment characteristics of this disease when occurring in the context of different malignancies. METHODS: A systematic literature review was performed based on database search in PubMed/Medline and included English articles until December 2016. RESULTS: In up to 20% of cases DM appears as a paraneoplastic syndrome associated with multiple malignancies such as ovarian, breast, prostate, lung, nasopharyngeal and colorectal cancer, and non-Hodgkin lymphomas...

Purpose The use of anthracycline chemotherapy is associated with heart failure (HF) among survivors of non-Hodgkin lymphoma (NHL). We aimed to understand the contribution of preexisting cardiovascular risk factors to HF risk among NHL survivors. Methods Using Danish registries, we identified adults diagnosed with aggressive NHL from 2000 to 2010 and sex- and age-matched general-population controls. We assessed HF from 9 months after diagnosis through 2012. We used Cox regression analysis to assess differences in risk for HF between survivors and general population controls...

Primary adrenal non-Hodgkin's lymphoma is rarely encountered. Clinical presentation is non-specific with fatigue, abdominal pain and B-symptoms being more commonly reported. We report a case of primary bilateral adrenal lymphoma who initially presented with clinical features suspicious for pheochromocytoma. The patient was recently diagnosed with hypertension and had a family history of early ischaemic heart disease. Plasma free metanephrines were also elevated. Pheochromocytoma was deemed unlikely following multiple investigations and the diagnosis of lymphoma was made following adrenal biopsy...

Platelets are megakaryocyte-derived nuclear-free fragments that participate in cardiovascular diseases including acute myocardial infarction, ischemic stroke, hypertension, and atherosclerosis. At the endothelium damage site, platelets interact with sub-endothelial matrix proteins such as glycoprotein VI/Fc receptor γ-chain (GPVI/FcRγ), G protein-coupled receptor/phospholipase Cγ(β) (GPCR/PLCγ(β)), Rho/RhoK and integrin. The activation of these signaling pathways triggers intracellular calcium increase and causes platelet adhesion, aggregation, granule release and finally thrombus formation...

An increased risk of arteriosclerosis has been noted in cancer survivors. Currently, there are only a few reports available that consider the risk of arteriosclerosis in patients treated with chemotherapy. Patients with an advanced stage B-cell malignant lymphoma are typically treated with a combination therapy of rituximab and cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP). Complications such as diabetes mellitus (DM), hyperlipidemia (HL), and osteoporosis due to prednisolone and cardiotoxicity due to anthracyclines are well known...

BACKGROUND Follicular B cell lymphomas account for a significant portion of all newly diagnosed non-Hodgkin's lymphomas. While involvement can be varied, the most common extranodal presentation is within the gastrointestinal tract beyond the stomach. In addition, the stomach has a diffuse multivessel vascular supply, which decreases the likelihood of developing ischemic gastritis.

We report on a 59-year-old woman who presented with nausea, fatigue, arterial hypertension, and acute renal failure. Clinical examination, laboratory findings of blood and urine and abdominal sonography were inconclusive. Renal biopsy revealed infiltration by a diffuse large B‑cell lymphoma. In fluorodeoxyglucose positron emission tomography/computed tomography tracer enrichment was demonstrated in both kidneys, skeletal system and retroperitoneal lymph nodes. Renal function improved already after the first cycle of R‑CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone)...
