Heria

Hepatic heria in adult without history of trauma or surgery is rare, and is sometimes operated under the diagnosis of lung or diaphragmatic tumor. Here, we report a case of hepatic hernia which had been preoperatively suspected of pleural tumor and surgically treated. At surgery, multiple lesions mimicking ectopic endometriosis were found on the diaphragma and hepatic profrusion was found from one of lesions.

Introduction: Accidents involving chainsaws are not uncommon in trauma care and may present as penetrating injuries with retention of a foreign object in the patient's chest. The current literature, however, does not present a consensus on the best way to approach these cases. Presentation of case: Male patient, 46-year-old man, born in Amazonas countryside, brought to the city of Manaus with a penetrating injury resulting from an accident with a chainsaw and retaining a 2cm sawtooth in his chest, six days after the event...

OBJECTIVE: To evaluate the clinical profile and predictors of mortality in neonates with congenital diaphragmatic hernia (CDH). METHODS: Demographic and clinical parameters of neonates with congenital diaphragmatic heria (n=37) between January 2014 and October, 2017 were reviewed, and compared among those who survived or expired in hospital. RESULTS: Median (range) gestation and birthweight were 38 (37-39) weeks and 2496 (2044-2889) g, respectively...

OBJECTIVE: Healthcare professionals is one of the risk groups to which influenza vaccination is recommended. The main objective was to know the attitudes of healthcare professionals about influenza vaccination in the Principality of Asturias' reference centre during the campaign 2017-2018. METHODS: We carried out a cross-sectional study between September 2017 and May 2018, using a questionnaire. Sociodemographic variables and reasons for accepting or refuse the influenza vaccination were studied...

OBJECTIVE: Extracellular nicotinamide phosphoribosyltransferase (eNAMPT) mediates inflammatory and potentially proatherogenic effects, whereas the role of intracellular NAMPT (iNAMPT), the rate limiting enzyme in the salvage pathway of nicotinamide adenine dinucleotide (NAD)+ generation, in atherogenesis is largely unknown. Here we investigated the effects of iNAMPT overexpression in leukocytes on inflammation and atherosclerosis. APPROACH AND RESULTS: Low-density lipoprotein receptor-deficient mice with hematopoietic overexpression of human iNAMPT (iNAMPThi ), on a western type diet, showed attenuated plaque burden with features of lesion stabilization...

BACKGROUND: Leukocyte migration is critical for the infiltration of monocytes and accumulation of monocyte-derived macrophages in inflammation. Considering that Hck and Fgr are instrumental in this process, their impact on atherosclerosis and on lesion inflammation and stability was evaluated. METHODS AND RESULTS: Hematopoietic Hck/Fgr-deficient, LDLr(-/-) chimeras, obtained by bone marrow transplantation, had smaller but, paradoxically, less stable lesions with reduced macrophage content, overt cap thinning, and necrotic core expansion as the most prominent features...

OBJECTIVE: The protein degrading activity of cathepsin C (CatC), combined with its role in leukocyte granule activation, suggests a contribution of this cystein protease in atherosclerosis. However, no experimental data are available to validate this concept. APPROACH AND RESULTS: CatC gene and protein expression were increased in ruptured versus advanced stable human carotid artery lesions. To assess causal involvement of CatC in plaque progression and stability, we generated LDLr(-/-)//CatC(-/-) chimeras by bone marrow transplantation...

AIMS: The SDF-1α/CXCR4 dyad was previously shown by us and others to be instrumental in intimal hyperplasia as well as early stage atherosclerosis. We here sought to investigate its impact on clinically relevant stages of atherosclerosis in mouse and man. METHODS AND RESULTS: Immunohistochemical analysis of CXCR4 expression in human atherosclerotic lesions revealed a progressive accumulation of CXCR4(+) cells during plaque progression. To address causal involvement of CXCR4 in advanced stages of atherosclerosis we reconstituted LDLr(-/-) mice with autologous bone marrow infected with lentivirus encoding SDF-1α antagonist or CXCR4 degrakine, which effects proteasomal degradation of CXCR4...

Pathological forms of left ventricular hypertrophy (LVH) often progress to heart failure. Specific transcription factors have been identified that activate the gene program to induce pathological forms of LVH. It is likely that apart from activating transcriptional inducers of LVH, constitutive transcriptional repressors need to be removed during the development of cardiac hypertrophy. Here, we report that the constitutive presence of Krüppel-like factor 15 (KLF15) is lost in pathological hypertrophy and that this loss precedes progression toward heart failure...

Cathepsin K (catK), a lysosomal cysteine protease, exerts strong elastinolytic and collagenolytic activity and is implicated in a range of pathological disorders including cardiovascular disease. CatK expression was found to be elevated in human aortic aneurysm pointing to a role in this vasculopathy. In the angiotensin II (Ang II)-induced mouse model for aneurysm formation, catK, S and C expression was strongly upregulated. Therefore, we investigated the effect of catK deficiency on Ang II-induced aneurysm formation in the abdominal aorta of apoE-/- mice...

OBJECTIVES: We aimed to investigate whether early thrombus formation can be visualized with in vivo magnetic resonance imaging (MRI) by the use of a novel bimodal alpha(2)-antiplasmin-based contrast agent (CA). BACKGROUND: Thrombus formation plays a central role in several vascular diseases. During the early phases of thrombus formation, activated factor XIII (FXIIIa) covalently cross-links alpha(2)-antiplasmin to fibrin, indicating the potential of alpha(2)-antiplasmin-based CAs in the detection of early thrombus formation...

BACKGROUND: With consideration of the central role of the innate immune system in atherogenesis and mannose-binding lectin (MBL) as an innate regulator of immunity, the role of MBL in experimental and human atherosclerosis was assessed. METHODS AND RESULTS: With the use of immunohistochemistry and polymerase chain reaction, deposition and gene expression of MBL-A and -C were assessed in murine atherosclerosis from mice deficient for the low-density lipoprotein receptor (LDLR(-/-)) after 10 or 18 weeks of high-fat feeding...

The myocardium of the failing heart undergoes a number of structural alterations, most notably hypertrophy of cardiac myocytes and an increase in extracellular matrix proteins, often seen as primary fibrosis. Connective tissue growth factor (CTGF) is a key molecule in the process of fibrosis and therefore seems an attractive therapeutic target. Regulation of CTGF expression at the promoter level has been studied extensively, but it is unknown how CTGF transcripts are regulated at the posttranscriptional level...

Surfactant protein D (SP-D) interacts with various different microorganisms and plays an important role in pulmonary innate immunity. SP-D expression has also been detected in extrapulmonary tissues, including the gastro-intestinal tract. However, its function in the intestine is unknown and may differ considerably from SP-D functions in the lung. Therefore, the effects of porcine SP-D (pSP-D) on several strains of intestinal bacteria were studied by means of bacterial growth assays, colony-count assays, radial diffusion assays and differential fluorescent staining...

Surfactant proteins A and D are pattern recognition molecules that play a role in pulmonary host defence. In this paper, we describe for the first time the expression and localisation of both collectins in various porcine tissues using a combination of in situ hybridisation (ISH), RT-PCR and immunohistochemistry (IHC). SP-D was expressed in several tissues including lung, tongue, intestinal tract, thymus, skin, gall bladder and lacrimal gland. Focal SP-D expression was detected in oesophagus, stomach, kidney, liver, prostate and spleen with both histological techniques...

BACKGROUND: The cell-associated proteoglycan syndecan-1 (Synd1) closely regulates inflammation and cell-matrix interactions during wound healing and tumorigenesis. The present study investigated whether Synd1 may also regulate cardiac inflammation, matrix remodeling, and function after myocardial infarction (MI). METHODS AND RESULTS: First, we showed increased protein and mRNA expression of Synd1 from 24 hours on, reaching its maximum at 7 days after MI and declining thereafter...

We tested the effect of Lactobacillus casei strain Shirota (LcS) on the murine model of ulcerative colitis induced by dextran sodium sulphate. The effect of LcS was tested either as a prophylactic 10 days before the onset of the disease, simultaneously with ulcerative colitis induction or continued 10 days after the disease was induced. LcS was not able to prevent the disease induction in any of the experiments. However, important clinical parameters including blood anemia indicators, body weight, and organ weight were improved in the animals receiving LcS as compared with the ulcerative colitis-induced controls...
