OBJECTIVE: The objective of this study was to retrospectively evaluate the possibility of using the brachial veins despite their deep location, small caliber, and thin wall. METHODS: There were 64 patients without superficial veins who were eligible for two-stage brachial vein transposition (BrVT); 54 patients were on hemodialysis, 9 patients had sickle cell disease, and 1 patient had long-term parenteral nutrition. Preoperative imaging was performed with color duplex ultrasound as well as venography for suspected central vein stenosis...

SurePath specimens from women referred to colposcopy were treated with Aptima Transfer Solution (ATS) before testing in Aptima HPV (AHPV) and Aptima HPV 16, 18/45 (AHPV-GT) assays. Untreated SurePath specimens were tested with the cobas HPV test. PreservCyt specimens were assessed for cytology and tested with AHPV. High-grade cervical intraepithelial neoplasia lesions served as the reference standard. Excellent agreement (95.5%; k=0.91) was observed for ATS-treated SurePath specimens between Tigris and Panther systems and between the PreservCyt and ATS-treated SurePath specimens (91...

Innate lymphoid cells (ILCs) fulfill important protective and reparative functions, and have thus been implicated in the maintenance of tissue homeostasis. Dysregulation of their activation is associated with several autoimmune and inflammatory diseases. The current literature on the role of ILCs in cancer is limited and our knowledge is therefore incomplete. Indeed, ILCs have been separately associated with tumor-promoting as well as tumor-suppressing activities, raising the need to understand the mechanisms by which these cells regulate tumor growth and progression toward a rational design of therapeutic approaches...

BACKGROUND: An accurate diagnosis of the leading health condition and comorbidities is a prerequisite for safe and effective rehabilitation. The problem of diagnostic errors in physical and rehabilitation medicine (PRM) has not been addressed sufficiently. The responsibility of a referring physician is to determine indications and contraindications for rehabilitation.

Abdominal aortic aneurysm is a disease seen in the elderly. Without intervention, an aneurysm can rupture which leads to death in most cases. Surgical resection was the gold standard treatment for many years but since two decades, endovascular repair has surged drastically. Less invasive and morbid than open repair, this technique has significantly evolved in the recent years. Nowadays the whole aorta can be treated with endovascular techniques in expert hands. This article presents an overview of different endovascular solutions and innovations in the management of aortic aneurysms...

INTRODUCTION: Traumatic brain injuries (TBIs) are a major public health, medical, and societal challenge globally. They present a substantial burden to victims, their families, and the society as a whole. Although indicators such as incidence or death rates provide insight into the occurrence and outcome of TBIs in various populations, they fail to quantify the full extent of their public health and societal impact. Measures such as years of life lost (YLLs), which quantifies the number of years of life lost because the person dies prematurely due to a disease or injury, should be employed to better quantify the population impact...

BACKGROUND: Although transplant benefit appears superior for patients with advanced hepatocellular cancer (HCC), liver transplantation remains limited to selected low-risk HCC patients to keep their outcomes similar to heterogeneous group of non-HCC patients. The purpose of this study was to assess the rationale for current policy of restricting access to liver transplantation to minority of HCC patients based on utility principle. METHODS: This retrospective cohort study comprised 1246 liver transplant recipients, including 206 HCC and 1040 non-HCC patients...

MicroRNAs (miRNAs) are small non-coding RNAs that have been identified in animals, plants, and viruses. These small RNAs play important roles in post-transcriptional regulation of various cellular processes, including development, differentiation, and all aspects of cancer biology. Rapid-onset T-cell lymphoma of chickens, namely Marek's disease (MD), induced by Gallid alphaherpesvirus 2 (GaHV2), could provide an ideal natural animal model for herpesvirus-related cancer research. GaHV2 encodes 26 mature miRNAs derived from 14 precursors assembled in three distinct gene clusters in the viral genome...

Atherosclerosis is a pro-inflammatory condition underlying many cardiovascular diseases. Platelet-activating factor (PAF) and interleukin 6 (IL-6) are actively involved in the onset and progression of atherosclerotic plaques. The involvement of monocyte-derived macrophages is well characterized in the installation of inflammatory conditions in the plaque, but less is known about the contribution of monocyte-derived dendritic cells (Mo-DCs). In the same way, the involvement of calcium, phospholipase C and A2 in PAF-induced IL-6 production, in different cells types, has been shown; however, the importance of the Jak/STAT pathway and its regulation by protein-tyrosine phosphatases in this response have not been addressed...

Telomeres protect the ends of vertebrate chromosomes from deterioration and consist of tandem nucleotide repeats (TTAGGG)n that are associated with a number of proteins. Shortening of the telomeres occurs during genome replication, thereby limiting the replication potential of somatic cells. To counteract this shortening, vertebrates encode the telomerase complex that maintains telomere length in certain cell types via de novo addition of telomeric repeats. Several herpesviruses, including the highly oncogenic alphaherpesvirus Marek's disease virus (MDV), harbor telomeric repeats (TMR) identical to the host telomere sequences at the ends of their linear genomes...

<i>Biotin-thiamine-responsive basal ganglia disease is a severe form of a rare neurogenetic disorder caused by pathogenic molecular variants in the thiamine transporter gene. Nowadays, a potentially effective treatment is known, therefore the early diagnosis is mandatory. The aim of the paper was to assess the contribution of neuropathological and magnetic resonance imaging (MRI) studies to a proper diagnosis. We present the brain study of two Polish patients with SLC19A3 mutations, including (1) an infant with an intriguing "walnut" appearance of the brain autopsied many years before the discovery of the SLC19A3 defect, and (2) a one-year-old patient with clinical features of Leigh syndrome...

The proper formation and function of neuronal networks is required for cognition and behavior. Indeed, pathophysiological states that disrupt neuronal networks can lead to neurodevelopmental disorders such as autism, schizophrenia or intellectual disability. It is well-established that transcriptional programs play major roles in neural circuit development. However, in recent years, post-transcriptional control of gene expression has emerged as an additional, and probably equally important, regulatory layer...

Marek's disease virus is a herpesvirus of chickens that costs the worldwide poultry industry more than US$1 billion annually. Two generations of Marek's disease vaccines have shown reduced efficacy over the last half century due to evolution of the virus. Understanding where the virus is present may give insight into whether continued reductions in efficacy are likely. We conducted a 3-yr surveillance study to assess the prevalence of Marek's disease virus on commercial poultry farms, determine the effect of various factors on virus prevalence, and document virus dynamics in broiler chicken houses over short (weeks) and long (years) timescales...

Adrenal incidentaloma (AI) includes all lesions with diameter ≥ 1 cm found incidentally during imaging examinations not associated with suspected adrenal pathology. Every adrenal incidentaloma requires a detailed hormonal and imaging assessment. Initial diagnosis includes radiological phenotypical evaluation (particularly in CT, or in case of contraindications - in MRI) and biochemical assessment of tumour hormonal activity (which includes cortisol circadian rhythm, salivary cortisol concentration, 24-hour urinary free-cortisol and metanephrines test, short cortisol and dexamethasone suppression test, ACTH level assessment, aldosterone and ARO concentration, adrenal androgen concentration)...

Marek's disease (MD), caused by Marek's disease virus (MDV), is a lymphotropic neoplastic disease. Previous miRNAome analysis showed gga-miR-219b was significantly downregulated in MDV-induced lymphoma, and one of its potential target genes, B-cell chronic lymphocytic /lymphoma 11B (BCL11B) was predicted. In this study, we further investigated the function of gga-miR-219b, and the gain/loss of function assay showed gga-miR-219b inhibited cell migration and reduced cell proliferation by promoting apoptosis not by cell cycle arrest...

BACKGROUND: High stability and disease-specific disarrangements suggest that microRNA molecules (miRNAs) present in body fluids are ideally suited for diagnostic applications, including gastric cancer (GC). However, the actual source of circulating miRNA biomarkers in GC has not been adequately evaluated, particularly in the Western populations that have some distinct characteristics compared with Asian patients. METHODS: Twenty treatment-naive patients with GC along with 20 cancer-free controls were recruited...

Marek's disease virus (MDV) and reticuloendotheliosis virus (REV) cause Marek's disease (MD) and reticuloendotheliosis (RE), respectively. Co-infection with MDV and REV is common in chickens, causing serious losses to the poultry industry. However, experimental studies of such co-infection are lacking. In this study, Chinese field strains of MDV (ZW/15) and REV (JLR1501) were used as challenge viruses to evaluate the pathogenicity of co-infection and the influence of MD vaccination in chickens. Compared to the MDV-challenged group, the mortality and tumor rates increased significantly by 20...
