S Mamedova
Purpose of the study - comparing of stillbirth rates and some of its risk factors in different options (after 22 and 28 completed weeks of gestation) of its registration. This study was conducted on the basis of a regional prenatal centre. Monitoring was conducted retrospectively with continuous coverage of all cases of completed pregnancy after 22 completed weeks of gestation. Stillbirth coefficient was calculated based on body weight (500 grams or more - I option, and a 1000 grams - II option) based on 100 of all birth cases (corresponding to 500 grams body weight or more, and 1,000 grams or more)...

Centre of mass is a fundamental anatomical and biomechanical parameter. Knowledge of centre of mass is essential to inform studies investigating locomotion and other behaviours, through its implications for segment movements, and on whole body factors such as posture. Previous studies have estimated centre of mass position for a range of organisms, using various methodologies. However, few studies assess the accuracy of the methods that they employ, and often provide only brief details on their methodologies...

AIMS: There is now evidence to support giving single-agent chemotherapy, radiotherapy or hypofractionated concurrent chemoradiotherapy to older patients with glioblastoma (GBM). However, the clinical basis on which treatment decisions are made is under-researched and not standardised. This retrospective, multicentre study assessed whether pre-morbid characteristics or tumour imaging features could predict for overall survival in a cohort of older patients with GBM. MATERIALS AND METHODS: Patients aged > 70 years, diagnosed with GBM at three neuro-oncology centres from 2010 to 2015 were retrospectively analysed...

BACKGROUND: The feasibility of using a multiple segment (full-body) kinematic model in clinical gait assessment is difficult when considering obstacles such as time and cost constraints. While simplified gait models have been explored in healthy individuals, no such work to date has been conducted in a stroke population. The aim of this study was to quantify the errors of simplified kinematic models for chronic stroke gait assessment. METHODS: Sixteen individuals with chronic stroke (>6months), outfitted with full body kinematic markers, performed a series of gait trials...

OBJECTIVE: Postoperative delayed wound healing, surgical site infections (SSIs), and other wound complications are associated with increased morbidity and health-care costs. In cardiothoracic surgery, wound complications can have life-threatening consequences. In recent years, negative pressure wound therapy (NPWT) has been applied over closed surgical incisions to help reduce tension and protect from external contamination. We report our initial experiences using a closed incision negative pressure therapy (ciNPT) over clean, closed sternotomy incisions at an Irish tertiary referral centre...

We investigate the excited state dynamics and the conformations of a new molecular donor-bridge-acceptor system, a Cu(ii)-phthalocyanine (CuPc) covalently linked via a flexible aliphatic spacer to a perylenebisimide (PBI). We performed time-resolved polarization anisotropy and pump-probe measurements in combination with molecular dynamics simulations. Our data suggest the existence of three conformations of the dyad: two more extended, metastable conformations with centre-of-mass distances >1 nm between the PBI and CuPc units of the dyad, and a highly stable folded structure, in which the PBI and CuPc units are stacked on top of each other with a centre-of-mass distance of 0...

INTRODUCTION: Prophylaxis is considered the optimal treatment for persons with moderate to severe haemophilia (factor activity between 1-5% of normal and <1% of normal respectively) in countries where safe factor concentrates are available and economically feasible. Historically, prophylactic treatment has not been well studied in the haemophilia B (HB) population due to difficulties in obtaining a sufficiently large sample. AIM: This study examines the prevalence of prophylaxis use among a robust sample of persons with HB in the United States and its association with specific demographic and clinical characteristics...

REVIEW
Lane Harper, Jeff Powell, Em M Pijl
Given the current opioid crisis around the world, harm reduction agencies are seeking to help people who use drugs to do so more safely. Many harm reduction agencies are exploring techniques to test illicit drugs to identify and, where possible, quantify their constituents allowing their users to make informed decisions. While these technologies have been used for years in Europe (Nightlife Empowerment & Well-being Implementation Project, Drug Checking Service: Good Practice Standards; Trans European Drugs Information (TEDI) Workgroup, Factsheet on Drug Checking in Europe, 2011; European Monitoring Centre for Drugs and Drug Addiction, An Inventory of On-site Pill-Testing Interventions in the EU: Fact Files, 2001), they are only now starting to be utilized in this context in North America...

BACKGROUND CONTEXT: Although lumbar disc herniations are common, only a small portion of these herniations lead to cauda equina syndrome (CES) which is an uncommon but debilitating disorder. Why some patients with herniation develop CES, when most do not, remains unknown. Pre-existing subclinical epidural lipomatosis may limit canal space such that an otherwise benign herniation causes CES. PURPOSE: This study determines whether patients with an acute disc herniation and CES have a greater body mass index (BMI) and greater quantity of epidural fat compared to control subjects with non-CES symptomatic lumbar herniated discs...

Anibh M Das, Sebene Mayorandan, Nils Janzen
Hepatorenal tyrosinaemia (HT1) is a serious condition that used to be fatal before the advent of nitisinone (NTBC, Orfadine®) as a therapeutic option. We have recently shown that selective screening is inadequate as initial symptoms are often uncharacteristic which leads to a considerable delay in diagnosis and treatment. This has a negative impact on morbidity and mortality as well as long-term outcome. For example, the odds ratio to develop hepatocellular carcinoma is 12.7 when treatment is initiated after the first birthday compared to start of treatment in the neonatal period...

The characteristics of a treadmill and the environment where it is based could influence the user's gaze and have an effect on their running kinematics and lower limb impacts. The aim of this study was to identify the effect of visual focus on spatio-temporal parameters and lower limb kinematics during treadmill running. Twenty six experienced runners ran at 3.33ms(-1) on a treadmill under two visual conditions, either looking ahead at a wall or looking down at the treadmill visual display. Spatio-temporal parameters, impact accelerations of the head and tibia, and knee and ankle kinematics were measured for the final 15s of a 90s bout of running under each condition...

In contrast to the glacier mass losses observed at other locations around the world, some glaciers in the High Mountains of Asia appear to have gained mass in recent decades. However, changes in digital elevation models indicate that glaciers in Karakoram and Pamir have gained mass, while recent laser altimetry data indicate mass gain centred on West Kunlun. Here, we obtain results that are essentially consistent with those from altimetry, but with two-dimensional observations and higher resolution. We produced elevation models using radar interferometry applied to bistatic data gathered between 2011 and 2014 and compared them to a model produced from bistatic data collected in 2000...
