Mortality, Health Care Use, and Costs of Weaning Center Survivors and Matched Prolonged ICU Stay Controls.

Background: Quantification of long-term survival, health care utilization, and costs of prolonged ventilator dependence informs patient/family decision-making, health care policy, and understanding of specialized weaning centers (SWCs) as alternate care models. Our objective was to compare survival trajectory, health care utilization, and costs of SWC survivors with a matched cohort of ≥ 21-d-stay ICU patients.

Methods: This was a retrospective longitudinal (12 y) case-control study linking to health administrative databases with matching on age, sex, Charlson comorbidity index, income quintiles, and days in ICU and hospital in preceding 12 months.

Chondrodysplasia and growth failure in children after early hematopoietic stem cell transplantation for non-oncologic disorders.

Bone dysplasias (osteochondrodysplasias) are a large group of conditions associated with short stature, skeletal disproportion, and radiographic abnormalities of skeletal elements. Nearly all are genetic in origin. We report a series of seven children with similar findings of chondrodysplasia and growth failure following early hematopoietic stem cell transplantation (HSCT) for pediatric non-oncologic disease: hemophagocytic lymphohistiocytosis or HLH (five children, three with biallelic HLH-associated variants [in PRF1 and UNC13D] and one with HLH secondary to visceral Leishmaniasis), one child with severe combined immunodeficiency and one with Omenn syndrome (both children had biallelic RAG1 pathogenic variants).

Stage I-II nodular lymphocyte-predominant Hodgkin lymphoma: a multi-institutional study of adult patients by ILROG.

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is an uncommon histologic variant, and the optimal treatment of stage I-II NLPHL is undefined. We conducted a multicenter retrospective study including patients ≥16 years of age with stage I-II NLPHL diagnosed from 1995 through 2018 who underwent all forms of management, including radiotherapy (RT), combined modality therapy (CMT; RT+chemotherapy [CT]), CT, observation after excision, rituximab and RT, and single-agent rituximab. End points were progression-free survival (PFS), freedom from transformation, and overall survival (OS) without statistical comparison between management groups.

Mini review shows that structured light plethysmography provides a non-contact method for evaluating breathing patterns in children.

Aim: Structured light plethysmography (SLP) is a novel light-based method that captures chest wall movements to evaluate tidal breathing. We carried out a narrative mini review of the clinical use of SLP in paediatrics.

Methods: PubMed and Google Scholar were searched for papers published in English up to December 2018.

A comparison of ultrasound with magnetic resonance imaging in the assessment of fetal biometry and weight in the second trimester of pregnancy: An observer agreement and variability study.

Objective: To compare the intra and interobserver variability of ultrasound and magnetic resonance imaging in the assessment of common fetal biometry and estimated fetal weight in the second trimester.

Methods: Retrospective measurements on preselected image planes were performed independently by two pairs of observers for contemporaneous ultrasound and magnetic resonance imaging studies of the same fetus. Four common fetal measurements (biparietal diameter, head circumference, abdominal circumference and femur length) and an estimated fetal weight were analysed for 44 'low risk' cases.

Diffuse Reflectance Spectroscopy as a Reliable Means of Comparing Ultraviolet Radiation-induced Erythema in Extreme Skin Colors.

Erythema is widely considered an indicator of skin cancer susceptibility, but assessments are challenging in black skin because melanin can mask erythema under traditional visual and advanced objective Commission Internationale de l'Eclairage (CIE) L*a*b* assessments. Using spectral measurements (400-700 nm) from a spectrophotometer, an algorithm was developed to measure erythema in white Caucasians (n = 9) and black West Africans (n = 11) 19-24 h postsolar simulated radiation (SSR) exposures to the volar forearm. The derived spectrum achieved showed a strong maximum peak for hemoglobin at 580 nm and a linear slope between 650 and 700 nm for melanin absorption, as reported by other authors.

HIV-related mortality at a district hospital in Botswana.

We reviewed mortality data among medical inpatients at a tertiary hospital in Botswana to identify risk factors for adverse inpatient outcomes. This review was a prospective analysis of inpatient admissions. All medical admissions to male and female medical wards were recorded over a six-month period between 1 November 2011 and 30 April 2012.

Free Open Access Medical Education resource knowledge and utilisation amongst Emergency Medicine trainees: A survey in four countries.

Introduction Free Open Access Medical Education encompasses a broad array of free online resources and discussion fora. The aim of this paper was to describe whether Emergency Medicine trainees in different contexts know about Free Open Access Medical Education, whether or not they know about its different platforms, which ones they use, and what the major barriers to regular usage are. Methods A convenience sample was surveyed on awareness and use of Free Open Access Medical Education blogs, podcasts, websites and Twitter at three institutions (in Australia, Botswana and Papua New Guinea) and one deanery (United Kingdom) between June 2013 and June 2014 using an online survey tool or via hand-distributed survey.

Optical in vivo imaging of the alarmin S100A9 in tumor lesions allows for estimation of the individual malignant potential by evaluation of tumor-host cell interaction.

Unlabelled: Tumors recruit and reprogram immune cells to support tumor development and spread, the most prominent among them being of monocytic origin such as tumor-associated macrophages (TAM) or myeloid-derived suppressor cells (MDSC). The alarmin S100A8/A9 has been implicated in the induction of TAM and MDSC. We assessed S100A9 as a molecular imaging marker for the activity of tumor-associated immune cells in a syngeneic murine breast cancer model.

The role of fibrinogen: a new paradigm in the treatment of coagulopathic bleeding.

Fibrinogen is involved in both primary and secondary hemostasis, playing an important role in platelet aggregation and the establishment of a fibrin network. Recent evidence suggests that very high levels of fibrinogen act as antithrombin and can reduce endogenous thrombin potential and compromise clot stability, particularly following a low tissue factor stimulus. Several laboratory methods for measuring plasma fibrinogen concentrations are available, but results vary depending on the type of method and the use of artificial colloid plasma expanders.

Non-word repetition in adolescents with specific language impairment and autism plus language impairments: a qualitative analysis.

Unlabelled: Non-word repetition (NWR) was investigated in adolescents with typical development, Specific Language Impairment (SLI) and Autism Plus language Impairment (ALI) (n=17, 13, 16, and mean age 14;4, 15;4, 14;8 respectively). The study evaluated the hypothesis that poor NWR performance in both groups indicates an overlapping language phenotype (Kjelgaard & Tager-Flusberg, 2001). Performance was investigated both quantitatively, e.

The spectra of clinical phenotypes in aplasia cutis congenita and terminal transverse limb defects.

The combination of aplasia cutis congenita (ACC) and terminal transverse limb defects (TTLD) is often referred to as the eponymous Adams-Oliver syndrome (AOS). The molecular basis of this disorder remains unknown, although the common occurrence of cardiac and vascular anomalies suggests a primary defect of vasculogenesis. Through the description of three previously unreported affected individuals, ascertained through the Adams-Oliver Syndrome European Consortium, we illustrate the phenotypic variability characteristically observed within extended families with AOS.

Mechanisms and alternative methods of achieving cardiac arrest.

Elective cardiac arrest during surgery can be achieved by inducing depolarization, polarization, or influencing calcium mechanisms. Depolarized arrest, induced by elevating the extracellular potassium concentration, is currently the most commonly used technique. However, injury associated with ionic imbalance involving sodium and calcium overload, together with maintained metabolic processes aimed at correcting these imbalances, have lead to alternatives being sought.

Hyperventilation and esophageal dysmotility in patients with noncardiac chest pain.
