OBJECTIVE: Previous research shows an association between obesity and attention deficit hyperactivity disorder (ADHD). The present study compares pre- and post-bariatric surgery patients using the internationally used Conners' Adult ADHD Rating Scale (CAARS™) to screen for ADHD. METHODS: Matched samples pre- (N = 120) and post-bariatric surgery (N = 128) were compared using self-rating instruments to assess ADHD-relevant symptomatology, depression, eating-related psychopathology, and BMI...

Cristiano Cervellera, Danilo Maccio
In this paper, we discuss how the extreme learning machine (ELM) framework can be effectively employed in the unsupervised context of multivariate density estimation. In particular, two algorithms are introduced, one for the estimation of the cumulative distribution function underlying the observed data, and one for the estimation of the probability density function. The algorithms rely on the concept of $F$-discrepancy, which is closely related to the Kolmogorov-Smirnov criterion for goodness of fit. Both methods retain the key feature of the ELM of providing the solution through random assignment of the hidden feature map and a very light computational burden...

Speech-language pathologists (SLPs) are trained to correct articulation of people diagnosed with motor speech disorders by analyzing articulators' motion and assessing speech outcome while patients speak. To assist SLPs in this task, we are presenting the Multimodal Speech Capture System (MSCS) that records and displays kinematics of key speech articulators, the tongue and lips, along with voice, using unobtrusive methods. Collected speech modalities, tongue motion, lips gestures, and voice, are visualized not only in real-time to provide patients with instant feedback but also offline to allow SLPs to perform post-analysis of articulators' motion, particularly the tongue, with its prominent but hardly visible role in articulation...

Although surveys suggest positive student attitudes toward the use of algorithm animations, it is not clear that they improve learning outcomes. The Graph Algorithm Animation Tool, or Galant, challenges and motivates students to engage more deeply with algorithm concepts, without distracting them with programming language details or GUIs. Even though Galant is specifically designed for graph algorithms, it has also been used to animate other algorithms, most notably sorting algorithms.

An Apple a Day keeps the Doctor Away - you may have heard the phrase more than once, as it has become so famous that translated versions circulate in a number of modern languages ["una mela al giorno toglie il medico di torno"]. More than three millennia before the concept of vitamins became common knowledge, ancient Egyptian and Babylonian text described a diet of liver to cure night blindness (Dowling & Wald, 1958). However, it took mankind a very long time to, from there, discover vitamins. This article is protected by copyright...

Burns are the most extensive forms of soft tissue injuries occasionally resulting in extensive and deep wounds and death. Burns can lead to severe mental and emotional distress, because of excessive scarring and skin contractures. Treatment of burns has always been a difficult medical problem and many different methods have been used to treat such injuries, locally. Biofilms are a collection of microorganisms that delay wound healing. One of the new methods of prevention and treatment of burn wound infections is application of antimicrobials, which act on biofilms and prevent the wound infection...

Supramolecular self-assembly is an important process that enables the conception of complex structures mimicking biological motifs. Herein, we constructed helical fibrils through chiral self-assembly of nucleobase-peptide conjugates (NPCs), where achiral nucleobases are helically displayed on the surface of fibrils, comparable to polymerized nucleic acids. Selective binding between DNA and the NPC fibrils was observed with fluorescence polarization. Taking advantage of metal-nucleobase recognition, we highlight the possibility of deposition/assembly of plasmonic nanoparticles onto the fibrillar constructs...

BACKGROUND: This study addresses whether a unitary cardiac autonomic nervous system index (ANSI), obtained combining multiple metrics from Heart Rate Variability (HRV) into a radar plot could provide an easy appreciation of autonomic performance in a clinical setting. MATERIALS AND METHODS: Data are standardized using percentile ranking of autonomic proxies from a relatively large reference population (n= 1593, age 39±13 years). Autonomic indices are obtained from autoregressive spectral analysis of (ECG derived) HRV at rest and during standing up...

Robust scientific evidence demonstrates that senes-cence induction in cancer works as a potent weapon to eradicate tumorigenesis. Therapies that enhance senescence not only promote a stable cell growth arrest but also work as a strong stimulus for the acti-vation of the antitumour immune response. However, recent advances suggest that if senescent tumour cells are not cleared from the tumours, they may promote tumour progression and metastasis. In this article, we focus on concepts that are relevant to a pro-senescence therapeutic approach, including caveats, and we propose therapeutic strategies that involve the combined use of pro-senescence therapies with im-munotherapies to promote the clearance of senescent tumour cells...

One concept how to improve anticancer effects of conventional metallodrugs consists in conjugation of these compounds with other biologically (antitumor) active agents, acting by a different mechanism. Here, we present synthesis, biological effects, and mechanisms of action of new Pt(II) derivatives containing one or two nonsteroidal anti-inflammatory diclofenac (DCF) ligands also known for their antitumor effects. The antiproliferative properties of these metallic conjugates show that these compounds are potent and cancer cell selective cytotoxic agents exhibiting activity in cisplatin resistant and the COX-2 positive tumor cell lines...

Military surgeons have gained familiarity and experience with mass casualty events (MCEs) as a matter of routine over the course of the last two conflicts in Afghanistan and Iraq. Over the same period of time, civilian surgeons have increasingly faced complex MCEs on the home front. Our objective is to summarize and adapt these combat surgery lessons to enhance civilian surgeon preparedness for complex MCEs on the home front. The authors describe the unique lessons learned from combat surgery over the course of the wars in Afghanistan and Iraq and adapt these lessons to enhance civilian surgical readiness for a MCE on the home front...

Guidelines are important tools for evidence-based pharmacological treatment of patients suffering from rheumatoid arthritis. Recommendations assist physicians in identifying the best form of treatment but ultimately, the final decision is based on joint participation by the patient and physician. Nowadays, general concepts, such as treat to target seem to be more important in rheumatoid arthritis than differencies between various drugs or drug classes. The universal recommendation to use methotrexate as the initial disease-modifying antirheumatic drug (DMARD) is driven more by economic reasons than by scientific data, which is not completely wrong but should be disclosed...

Highly multiplexed point of care tests could improve diagnostic accuracy and differential diagnostic capacity in for instance emergency medicine and low resource environments. Available technology platforms for POC biomarker detection are typically simplex or low-plexed, whereas common lab-based microarray systems allow for the simultaneous detection of thousands of DNA or protein biomarkers. In this study, we demonstrate a novel suspension particle array platform that utilizes 900 μm bricks for POC amenable colorimetric biomarker detection with an encoding capacity of over two million...

Ischemic placental disease is a concept that links intrauterine growth retardation (IUGR) and preeclampsia (PE) back to insufficient remodeling of uterine spiral arteries. The rheological consequences of insufficient remodeling of uterine spiral arteries were hypothesized to mediate the considerably later manifestation of obstetric disease. However, the micro-rheology in the intervillous space (IVS) cannot be examined clinically and rheological animal models of the human IVS do not exist. Thus, an in silico approach was implemented to provide in vivo inaccessible data...

A promising new concept is the application of flexible and foldable conductive film or paper for wearable electronics, in which silver nanowires, carbon nanotubes and graphene are primarily used as conductive materials. However, their insufficient nanostructure contacts lead to poor electrical conductivity and mechanical fracture. Here, we demonstrate a simple and innovative strategy for fabricating a free-standing silver film with inverted pyramids by replicating pyramids on a textured silicon wafer under a hydrothermal reaction...

BACKGROUND: The developmental origin of health and disease concept identifies the brain, cardiovascular, liver, and kidney systems as targets of fetal adverse programming with adult consequences. As the limits of viability in premature infants have been pushed to lower gestational ages, the long-term impact of prematurity on kidneys still remains a significant burden during hospital stay and beyond. OBJECTIVES: The purpose of this study is to summarize available evidence, mechanisms, and short- and long-term renal consequences of prematurity and identify nephroprotective strategies and areas of uncertainty...
