#1
Francesca Martelli, Eduardo Palermo, Stefano Rossi
The aim of the study is to design a novel protocol to characterize the ankle movements during dorsal and plantar flexion reaching tasks using the pediAnklebot. Five healthy children were instructed to control a pointer and hit targets appearing on the monitor, by moving their ankle alternatively up and down. The protocol consisted of 60 targets, 30 up and 30 down, reachable via dorsiflexion and plantarflexion movements, respectively. Ankle angular displacements and torques were gathered by encoders and load cells embedded in the robot...

Importance: Previous studies of resident attrition have variably included preliminary residents and likely overestimated categorical resident attrition. Whether program director attitudes affect attrition has been unclear. Objectives: To determine whether program director attitudes are associated with resident attrition and to measure the categorical resident attrition rate. Design, Setting, and Participants: This multicenter study surveyed 21 US program directors in general surgery about their opinions regarding resident education and attrition...

A significant challenge faced by visually impaired people is 'wayfinding', which is the ability to find one's way to a destination in an unfamiliar environment. This study develops a novel wayfinding system for smartphones that can automatically recognize the situation and scene objects in real time. Through analyzing streaming images, the proposed system first classifies the current situation of a user in terms of their location. Next, based on the current situation, only the necessary context objects are found and interpreted using computer vision techniques...

Several psychologists have paid attention to individual differences in deception detection, but only a few studies have found significant results. The present study aimed to explore the relationship between attachment anxiety and deception judgment when there are no obvious cues to distinguish lies from truth, and to examine the moderating effect of motives. Participants were instructed to judge each of 10 audios on whether they were true or false. Subsequently, the attachment anxiety of participants was assessed using the Experiences in Close Relationships questionnaire...

Compensatory changes as a result of auditory deprivation in the deaf lead to higher visual processing skills. In two experiments, we explored if such brain plasticity in the deaf modulates processing of masked stimuli in the visual modality. Deaf and normal-hearing participants responded to targets either voluntarily or by instruction. Masked primes related to the response were presented briefly before the targets at the center and the periphery. In Experiment 1, targets appeared only at the foveal region whereas, in Experiment 2, they appeared both at the fovea and the periphery...

BACKGROUND: Gait modifications can reduce the knee adduction moment, a representation of knee loading. Reduced loading may help to slow progression of medial knee osteoarthritis. We aimed to investigate the response of patients with medial knee osteoarthritis to direct feedback on the knee adduction moment as a method for modifying the gait pattern, before and after training with specific gait modifications. METHODS: Forty patients with medial knee osteoarthritis underwent 3D gait analysis on an instrumented-treadmill, while receiving real-time feedback on the peak knee adduction moment...

This study replicated prior research on college students' perceived descriptive norms (i.e., prevalence estimates) forintimate partner violence (IPV). In this study, male and female college students were instructed to estimate the prevalence of physical forms of IPV for "typical students" of their same gender on campus. Perpetrators of IPV-both male and female-made higher estimates than nonperpetrators. When compared to actual prevalence rates, both perpetrators and nonperpetrators overestimated the prevalence of IPV on campus...

BACKGROUND AND PURPOSE: To explore the methods of clinical classification in chronic radiation-induced ulcers in the chest wall (CRUCWs). MATERIALS AND METHODS: A total of 64 patients with CRUCWs were treated. We divided the cases into 3 types (mild, moderate, or severe) according to their clinical manifestations. Conservative treatments, axial-pattern myocutaneous or local flaps, or filleted flaps were applied correspondingly. RESULTS: The cases were divided as follows: mild (n = 11), moderate (n = 45), and severe (n = 8)...

The objective of this study was to examine the content validity and test-retest reliability of the Intuitive Eating Scale among pregnant women. A qualitative think-aloud study of the Intuitive Eating Scale analysed the content validity. Overall, the Intuitive Eating Scale made sense to pregnant women, but food safety affected the interpretation of some items. A version with instructions modified accounting for food safety, the Intuitive Eating Scale-Pregnancy, was subsequently shown to have stable scores over 5 weeks during the second trimester, mean change = -0...

Background For secondary prevention of acute coronary syndrome, guidelines recommend dual antiplatelet therapy (DAPT) with acetylsalicylic acid and a P2Y12 receptor antagonist such as clopidogrel, prasugrel or ticagrelor for a period of 12 months. Often, uncertainty exists with respect to surgical or diagnostic procedures in these high-risk patients: can the DAPT be continued without interruption? If not, what is the recommended withdrawal strategy? What should be considered for the perioperative management? Methods An interdisciplinary group of experienced experts in the fields of cardiology, cardiac surgery, gastroenterology, anaesthesiology, intensive care and haemostaseology developed recommendations relevant to daily clinical practice based on the current scientific evidence...

In this experiment, we demonstrate a suite of hybrid Brain-Computer Interface (BCI)-based paradigms that are designed for two applications: assessing the level of consciousness of people unable to provide motor response and, in a second stage, establishing a communication channel for these people that enables them to answer questions with either 'yes' or 'no'. The suite of paradigms is designed to test basic responses in the first step and to continue to more comprehensive tasks if the first tests are successful...

Neurofibromatosis type 1 (NF1) is a rare autosomal dominant disease linked to mutations of the Nf1 gene. Patients with NF1 commonly experience severe pain. Studies on mice with Nf1 haploinsufficiency have been instructive in identifying sensitization of ion channels as a possible cause underlying the heightened pain suffered by patients with NF1. However, behavioral assessments of Nf1 mice have led to uncertain conclusions about the potential causal role of Nf1 in pain. We used the clustered regularly interspaced short palindromic repeats (CRISPR)-associated 9 (CRISPR/Cas9) genome editing system to create and mechanistically characterize a novel rat model of NF1-related pain...

This paper presents the results of two cognitive load studies comparing three augmented reality display technologies: spatial augmented reality, the optical see-through Microsoft HoloLens, and the video see-through Samsung Gear VR. In particular, the two experiments focused on isolating the cognitive load cost of receiving instructions for a button-pressing procedural task. The studies employed a self-assessment cognitive load methodology, as well as an additional dual-task cognitive load methodology. The results showed that spatial augmented reality led to increased performance and reduced cognitive load...

Blood clots stop bleeding and provide cell-instructive microenvironments. Still, in vitro models used to study implant performance typically neglect any possible interactions of recruited cells with surface-adhering blood clots. Here we study the interaction and synergies of bone marrow derived human mesenchymal stem cells (hMSCs) with surface-induced blood clots in an in vitro model by fluorescence microscopy, scanning and correlative light and electron microscopy, ELISA assays and zymography. The clinically used alkali-treated rough titanium (Ti) surfaces investigated here are known to enhance blood clotting compared to native Ti and to improve the healing response, but the underlying mechanisms remain elusive...

A significant number of U.S. health sciences libraries have closed since the mid-1990's. A pilot study was conducted with academic physicians to understand the impact of closing the health sciences library in the teaching hospital with which they were affiliated. A brief survey was designed and distributed to fourteen faculty members with thirteen useable responses received. The study elicited a context-sensitive perspective on the closing of the library with the most noteworthy outcome being the additional time required by attending physicians and trainees to perform the work that previously was performed by library staff...

REVIEW
Maria Almonacid, Marie-Emilie Terret, Marie-Hélène Verlhac
The position of the nucleus in a cell can instruct morphogenesis in some cases, conveying spatial and temporal information and abnormal nuclear positioning can lead to disease. In oocytes from worm, sea urchin, frog and some fish, nucleus position regulates embryo development, it marks the animal pole and in Drosophila it defines the future dorso-ventral axis of the embryo and of the adult body plan. However, in mammals, the oocyte nucleus is centrally located and does not instruct any future embryo axis. Yet an off-centre nucleus correlates with poor outcome for mouse and human oocyte development...

Jan Roth
Tourette syndrome (TS) is a common neuropsychiatric disorder, more common in males than females, with onset before age 18. TS is characterized by multiple motor tics and one or more vocal/phonic tics, persisting for more than a year. Tics are unvoluntary, abrupt, rapid, repetitive, but non-rhythmic movements or sounds (vocalizations). They are preceded by an inner urge. Tics can be temporarily suppressed, but this leads to a powerful re-emergence. The performance of tics results in immediate but transient relief...
