Genomic alterations accompanying tumour evolution in colorectal cancer: tracking the differences between primary tumours and synchronous liver metastases by whole-exome sequencing.

Background: Colorectal cancer (CRC) patients with metastatic disease can become cured if neoadjuvant treatment can enable a resection. The search for predictive biomarkers is often performed on primary tumours tissue. In order to assess the effectiveness of tailored treatment in regard to the primary tumour the differences in the genomic profile needs to be clarified.

Cancer immune therapy for lymphoid malignancies: recent advances.

Immunotherapy has played an important part in improving the life of patients with lymphoproliferative diseases especially since the addition of rituximab to chemotherapy in the CD20-positive neoplasms in the 1990s. While this field of passive immunotherapy is continuously evolving, several breakthroughs will expand the treatment modalities to include more active immunotherapy. With the approval of immune checkpoint-blocking antibodies for Hodgkin lymphoma and bispecific antibodies for acute lymphoblastic leukemia (ALL), activation of endogenous T cells already plays a role in several lymphoid malignancies.

Up-front rituximab maintenance improves outcome in patients with follicular lymphoma: a collaborative Nordic study.

The introduction of the anti-CD20 antibody rituximab in combination with chemotherapy (R-chemo) has improved the prognosis of patients with follicular lymphoma (FL). During the last decade, the addition of a maintenance treatment with rituximab (MR) after R-chemo has been tested with the hope of further improving the outcome of these patients. Using 2 independent population-based cohorts, we investigated the effect of up-front MR on time related end points as well as the risk of histological transformation (HT).

Can copeptin and troponin T ratio predict final infarct size and myocardial salvage index in patients with ST-elevation myocardial infarction: A sub-study of the DANAMI-3 trial.

Background: Primary percutaneous coronary intervention (pPCI) is recommended in patients presenting with ST-elevation myocardial infarction (STEMI) within <12 h of symptom onset. However, patients-reported symptom duration is not always reliable. Cardiac specific troponin T (cTnT) and the endogenous stress marker copeptin have different temporal release patterns for myocardial infarction MI.

Thyroid function in hidradenitis suppurativa: a population-based cross-sectional study from Denmark.

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory disease. Numerous studies have associated HS with obesity, and recently with metabolic syndrome (MetS). Both obesity and MetS are linked with metabolic changes.

Adipose-derived stem cells for treatment of chronic ulcers: current status.

Chronic ulcers remain a difficult challenge in healthcare systems. While treatment options are limited, stem cells may be a novel alternative. Adipose-derived stem cells (ADSC) have become increasingly popular compared with bone marrow-derived stem cells as they are far easier to harvest.

Thromboembolism prophylaxis in patients with Philadelphia-negative myeloproliferative neoplasms-Clinical practice among Nordic specialists.

Background: Patients with Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs) have higher risks of developing thromboembolisms compared to the general population. International guidelines on the management of MPNs therefore include recommendations concerning thromboembolism prophylaxis. In clinical practice, strict adherence to guidelines may be challenging and dependent on factors such as physician experience, outpatient clinic setting, and access to therapy; however, no data exist on physician adherence or patient compliance to thromboembolism prophylaxis in MPNs.

Induced hypothermia in patients with septic shock and respiratory failure (CASS): a randomised, controlled, open-label trial.

Background: Animal models of serious infection suggest that 24 h of induced hypothermia improves circulatory and respiratory function and reduces mortality. We tested the hypothesis that a reduction of core temperature to 32-34°C attenuates organ dysfunction and reduces mortality in ventilator-dependent patients with septic shock.

Methods: In this randomised, controlled, open-label trial, we recruited patients from ten intensive care units (ICUs) in three countries in Europe and North America.

A retrospective analysis of adverse effects of an in vivo fluoroquinolone antibiotic enrofloxacin treatment on oocyte quality in the common marmoset.

Here we report a retrospective analysis of negative effects of routine enrofloxacin treatment of recurrent diarrhea on the ovary and the developing oocytes of the common marmoset, a small New World primate. The most deleterious effect on oocytes was observed about two months post treatment suggesting that the enrofloxacin effect is on early growing follicles. Manifestations of toxicity included decreased numbers of growing follicles and recovered culturable oocytes, as well as signs of early atresia of granulosa cells.

Kidney transplant outcomes from older deceased donors: a paired kidney analysis by the European Renal Association-European Dialysis and Transplant Association Registry.

As the median age of deceased kidney donors rises, updated knowledge of transplant outcomes from older deceased donors in differing donor-recipient age groups is required. Using ERA-EDTA Registry data we determined survival outcomes of kidney allografts donated from the same older deceased donor (55-70 years), and transplanted into one recipient younger and one recipient of similar age to the donor. The recipient pairs were divided into two groups: group 1; younger (median age: 52 years) and older (60 years) and group 2; younger (41 years) and older (60 years).

Oral Magnesium Supplementation in Chronic Kidney Disease Stages 3 and 4: Efficacy, Safety, and Effect on Serum Calcification Propensity-A Prospective Randomized Double-Blinded Placebo-Controlled Clinical Trial.

Introduction: Chronic kidney disease (CKD) is associated with high cardiovascular morbidity and mortality. Recent evidence suggests that increases in both serum and intracellular magnesium (Mg) can slow or even prevent the development of vascular calcification seen in CKD. Serum calcification propensity () is a novel functional test, which is associated with all-cause mortality in CKD and measures the ability of serum to delay the formation of crystalline nanoparticles.

The digital environment in men's sexual disorders: A systematic review.

Context: The revolution of digital technologies constitutes a new setting for the patient-physician relationship and provides patients with a scenario of privacy and universal access to a vast amount of information. However, there is little information on how digital resources are used and what their advantages and disadvantages are.

Objectives: To explore the scope of the scientific research on the use of digital technology related to men's sexual disorders and to analyze the primary sources of digital information related to this field.

Impact of transducer frequency setting on speckle tracking measures.

Speckle tracking echocardiography is an emerging technique, which is currently being included in clinical guidelines. We sought to investigate the impact of transducer frequency settings on speckle tracking derived measures. The study comprised of 22 subjects prospectively enrolled for a randomized controlled trial (LOOP-study, Clinicaltrials.

Safety, efficacy and drug survival of biologics and biosimilars for moderate-to-severe plaque psoriasis.

Background: Real-life data on newer biological and biosimilar agents for moderate-to-severe psoriasis are lacking.

Objectives: To examine safety, efficacy and time to discontinuation (drug survival) of biologics (adalimumab, etanercept, infliximab, secukinumab and ustekinumab) and compare originators with biosimilars (i.e.

Effects of rituximab and dexamethasone on regulatory and proinflammatory B-cell subsets in patients with primary immune thrombocytopenia.

Objective: To investigate the cytokine production and surface marker composition of B cells in adult patients with newly diagnosed primary immune thrombocytopenia (ITP) before and 12 months after treatment with rituximab + dexamethasone (RTX+DXM) or dexamethasone (DXM).

Methods: Peripheral blood mononuclear cells were isolated from nine patients treated with RTX+DXM, seven patients treated with DXM, and seven healthy donors. Expression of the cell-surface markers CD5, CD27, CD25, and CD19, and intracellular content of IL-6 and IL-10 were measured by flow cytometry.

Reactive oxygen species inhibit catalytic activity of peptidylarginine deiminase.

Protein citrullination catalysed by peptidylarginine deiminase (PAD) may play an important pathogenic role in several chronic inflammatory diseases and malignancies. PAD2, PAD4, and citrullinated proteins are found in the synovium of rheumatoid arthritis patients. PAD activity is dependent on calcium and reducing conditions.

Short-term results of self-expanding metal stents for acute malignant large bowel obstruction.

Aim: Self-expanding metal stents (SEMSs) can be used as a palliative treatment or to initially decompress colon prior to definitive surgery (as a so-called 'bridge to surgery'). The purpose of this study was to investigate the efficacy and safety of SEMS used as palliation and bridge to surgery for malignant large bowel obstruction.

Method: A multicentre retrospective study was conducted from January 2010 to December 2013 to identify patients undergoing stent placement for acute large bowel obstruction.

Pain during topical photodynamic therapy - comparing methyl aminolevulinate (Metvix) to aminolaevulinic acid (Ameluz); an intra-individual clinical study.

Background: Actinic keratoses are often treated by photodynamic therapy. However, the main side effect of this treatment is pain during and shortly after illumination.

Objectives: To evaluate, in an intra-individual study, whether the pain response differ in treatment of actinic keratoses in scalp and forhead, using branded methyl aminolevulinate (MAL) and aminolaevulinic acid (ALA).

Cell-Free DNA in Metastatic Colorectal Cancer: A Systematic Review and Meta-Analysis.

Background: Circulating DNA can be detected and quantified in the blood of cancer patients and used for detection of tumor-specific genetic alterations. The clinical utility has been intensively investigated for the past 10 years. The majority of reports focus on analyzing the clinical potential of tumor-specific mutations, whereas the use of total cell-free DNA (cfDNA) quantification is somehow controversial and sparsely described in the literature, but holds important clinical information in itself.

Dynamic optical coherence tomography of skin blood vessels - proposed terminology and practical guidelines.

Background: Dynamic optical coherence tomography (D-OCT) has recently been introduced in dermatology. In contrast to 'Standard' OCT imaging, which exclusively relies on the morphological analysis of the tissue, D-OCT allows the in vivo visualization of blood flow. Preliminary D-OCT data showed differences in the vascularization of nevus to melanoma transition, suggesting that this technology may help to differentiate between benign and malignant lesions.

Epigenetic changes in myelofibrosis: Distinct methylation changes in the myeloid compartments and in cases with ASXL1 mutations.

This is the first study to compare genome-wide DNA methylation profiles of sorted blood cells from myelofibrosis (MF) patients and healthy controls. We found that differentially methylated CpG sites located to genes involved in 'cancer' and 'embryonic development' in MF CD34+ cells, in 'inflammatory disease' in MF mononuclear cells, and in 'immunological diseases' in MF granulocytes. Only few differentially methylated CpG sites were common among the three cell populations.
