Best practice recommendations for medically assisted reproduction in patients with known cardiovascular disease or at high risk of cardiovascular disease.

Increasing numbers of people are seeking assisted conception. In people with known cardiac disease or risk factors for cardiac disease, assisted conception may carry increased risks during treatment and any subsequent pregnancy. These risks should be assessed, considered and minimized prior to treatment.

3D microelectrode arrays, pushing the bounds of sensitivity toward a generic platform for point-of-care diagnostics.

The increased sensitivity of microelectrode arrays (MEAs) over macroelectrodes for biosensing is well established, and results from reducing the diffusion gradient of the target species to and from the electrode surfaces. The current study describes the fabrication and characterisation of a polymer-based MEA, which exploits the advantages of three dimensionality (3D). Firstly, the unique 3D formfactor promotes release of the gold tips from an inert layer in a controlled fashion, to form a highly reproducible array of microelectrodes in a single step.

Guideline on the peri-operative management of patients with sickle cell disease: Guideline from the Association of Anaesthetists.

Sickle cell disease is a multisystem disease characterised by chronic haemolytic anaemia, painful vaso-occlusive crises and acute and chronic end-organ damage. It is one of the most common serious inherited single gene conditions worldwide and has a major impact on the health of affected individuals. Peri-operative complications are higher in patients with sickle cell disease compared with the general population and may be sickle or non-sickle-related.

Secondary colonic stent insertion in acute large bowel obstruction following primary stent failure.

Introduction: Colonic stent insertion has been shown to be an effective treatment for patients with acute large bowel obstruction, either as a bridge to surgery or as definitive treatment. However, little is known of the role of secondary stent insertion following primary stent failure in patients considered inappropriate or high risk for emergency surgery.

Methods: Fourteen patients presenting with acute large bowel obstruction who had previously been treated with colonic stent insertion were studied.

Robust adaptive immune response against infection marked by low parasitemia in a murine model of sickle cell disease.

The intraerythrocytic parasite is the number 1 cause of transfusion-transmitted infection and can induce serious, often life-threatening complications in immunocompromised individuals including transfusion-dependent patients with sickle cell disease (SCD). Despite the existence of strong long-lasting immunological protection against a second infection in mouse models, little is known about the cell types or the kinetics of protective adaptive immunity mounted following infection, especially in infection-prone SCD that are thought to have an impaired immune system. Here, we show, using a mouse infection model, that infected wild-type (WT) mice mount a very strong adaptive immune response, characterized by (1) coordinated induction of a robust germinal center (GC) reaction; (2) development of follicular helper T (T) cells that comprise ∼30% of splenic CD4 T cells at peak expansion by 10 days postinfection; and (3) high levels of effector T-cell cytokines, including interleukin 21 and interferon γ, with an increase in the secretion of antigen (Ag)-specific antibodies (Abs).

A library of recombinant Babesia microti cell surface and secreted proteins for diagnostics discovery and reverse vaccinology.

Human babesiosis is an emerging tick-borne parasitic disease and blood transfusion-transmitted infection primarily caused by the apicomplexan parasite, Babesia microti. There is no licensed vaccine for B. microti and the development of a reliable serological screening test would contribute to ensuring the safety of the donated blood supply.

Viscoelastometry guided fresh frozen plasma infusion for postpartum haemorrhage: OBS2, an observational study.

Background: Postpartum haemorrhage (PPH) can be exacerbated by haemostatic failure. Based on data from trauma studies, empirical infusions of fresh frozen plasma (FFP) are often given during severe PPH if coagulation tests are unavailable. This study observed a cohort of women with moderate/severe PPH in whom FFP infusion was guided by the use of viscoelastometric point-of-care testing (VE-POCT) and clinical assessment.

Viscoelastometric-guided early fibrinogen concentrate replacement during postpartum haemorrhage: OBS2, a double-blind randomized controlled trial.

Background: Postpartum haemorrhage (PPH) can be exacerbated by haemostatic failure. We hypothesized that early fibrinogen replacement, guided by viscoelastometric testing, reduces blood product usage and bleed size.

Methods: Women with PPH 1000-1500 ml were enrolled.

Gastrointestinal clear cell sarcoma-like tumour of the ascending colon.

Introduction: A clear cell sarcoma-like gastrointestinal tumour (CCSLGT) is a rare malignant soft tissue sarcoma. In the literature, they are sometimes referred to as malignant gastrointestinal neuroectodermal tumours, clear cell sarcomas or osteoclast rich tumours of the gastrointestinal tract.

Case History: We present a case of a CCSLGT arising from the ascending colon of a previously well 22-year-old man presenting with abdominal pain and anaemia.

Fibrinogen concentrate versus placebo for treatment of postpartum haemorrhage: study protocol for a randomised controlled trial.

Background: Postpartum haemorrhage (PPH) is a major cause of maternal morbidity. Bleeding is caused by a combination of physical causes, such as failure of the uterus to contract or operations, and is made worse by impairment of the blood clotting system. A number of studies have shown that low levels of the blood clotting factor fibrinogen are associated with progression of bleeding, the need for invasive interventions and transfusions of red blood cells and fresh frozen plasma (FFP).
