The purpose of the study was to quantify the average and maximum distances traveled by NCAA division I football athletes during competitive games. Utilizing global positioning system (GPS) devices (Catapult Sports), total and low, moderate and high speed distances were quantified by each position. Understanding maximal workloads can enhance conditioning practice periodization protocols. A total of 40 football athletes were included in the analysis. For the data to be included, athletes were required to participate in ≥ 75% of the offensive or defensive snaps for any given game...

BACKGROUND: Patients with inflammatory bowel disease (IBD) require regular follow-up to manage their care, which requires significant amount of time and out-of-pocket costs. Telemedicine in the form of video virtual visits could serve as an alternative to in-office visits. The aim of this project was to understand if telemedicine can provide high value care (defined as quality/cost) to outpatients with IBD. METHODS: Patients who participated in the IBD telemedicine clinic in the second half of 2015 were included...

Piezoelectric wafer active sensors (PWAS) are commonly used for detecting Lamb waves for structural health monitoring application. However, in most applications of active sensing, the signals are of high-amplitude and easy to detect. In this article, we have shown a new avenue of using the PWAS transducer for detecting the low-amplitude fatigue-crack related acoustic emission (AE) signals. Multiphysics finite element (FE) simulations were performed with two PWAS transducers bonded to the structure. Various configurations of the sensors were studied by using the simulations...

OBJECTIVE: To examine the association between distance traveled for an abortion and site of postabortion care among low-income women. METHODS: We conducted a retrospective cohort study using claims data from 39,747 abortions covered by California's Medicaid program in 2011-2012. Primary outcomes were the odds of abortion-related visits to an emergency department (ED) and the original abortion site, and the secondary outcome was total abortion care costs. We used mixed-effects logistic regression adjusting for patient and abortion characteristics to examine the associations between distance traveled and subsequent abortion-related care at each location...

During the summers of 2015 and 2016, the United Kingdom experienced large outbreaks of cyclosporiasis in travellers returning from Mexico. As the source of the outbreaks was not identified, there is the potential for a similar outbreak to occur in 2017; indeed 78 cases had already been reported as at 27 July 2017. Early communication and international collaboration is essential to provide a better understanding of the source and extent of this recurring situation.

The σ subunit of bacterial RNA polymerase is required for promoter recognition during transcription initiation but may also regulate transcription elongation. The principal σ(70) subunit of Escherichia coli was shown to travel with RNA polymerase and induce transcriptional pausing at promoter-like motifs, with potential regulatory output. We recently demonstrated that an alternative σ(38) subunit can also induce RNA polymerase pausing. Here, we outline proposed regulatory roles of σ-dependent pausing in bacteria and discuss possible interplay between alternative σ variants and regulatory factors during transcription elongation...

The arm swing in hockey skating can have a positive effect on the forces produced by each skate, and the resulting velocity from each push off. The main purpose of this study was to measure the differences in ground reaction forces (GRFs) produced from an anteroposterior versus a mediolateral style hockey skating arm swing. Twenty-four elite-level female hockey players performed each technique while standing on a ground-mounted force platform, and all trials were filmed using two video cameras. Force data was assessed for peak scaled GRFs in the frontal and sagittal planes, and resultant GRF magnitude and direction...

Rongrong Chen, Diederick C Niehorster, Li Li
Previous studies have proposed that people can use visual cues such as the instantaneous direction (i.e., heading) or future path trajectory of travel specified by optic flow or target visual direction in egocentric space to steer or walk toward a goal. In the current study, we examined what visual cues people use to guide their goal-oriented locomotion and whether their reliance on such visual cues changes as travel speed increases. We presented participants with optic flow displays that simulated their self-motion toward a target at various travel speeds under two viewing conditions in which we made target egocentric direction available or unavailable for steering...

OBJECTIVE: Sufficient sleep is required for weight maintenance. Sleep deprivation due to noise exposure stimulates weight gain by increasing hyperphagia and reducing energy expenditure (EE). Yet the mechanistic basis underlying the weight gain response is unclear. Orexin-A promotes arousal and negative energy balance, and orexin terminals project to the ventrolateral preoptic area (VLPO), which is involved in sleep-to-wake transitions. To determine whether sleep deprivation reduces orexin function in VLPO and to test the hypothesis that sleep deprivation would attenuate the orexin-A-stimulated increase in arousal, physical activity (PA), and EE...

The author contends that, contrary to the usual perception that Winnicott followed a linear progression "through pediatrics to psychoanalysis," Winnicott's vision was always a psychoanalytic one, even during his early pediatric work. His place in the development of psychoanalytic theory is highlighted, and the author discusses such key Winnicottian concepts as transitional space, the false self, and the use of the object. Winnicott's unique approach to the form and value of analytic interpretation is particularly emphasized, and his thoughts on the treatment of depression are also addressed, as well as his distinction between regression and withdrawal...

BACKGROUND: Headache attributed to airplane travel, also named "airplane headache" (AH) is a headache that occurs during take-off and landing. Today, there are still uncertainties about the pathophysiology and treatment of AH. This systematic review was performed to facilitate identification of the existing literature on AH in order to discuss the current evidence and areas that remain to be investigated in AH. METHODS: The systematic literature search was performed in 3 relevant medical databases; PubMed, Scopus, and Embase...

Fluorescence activated cell sorting (FACS) has become an essential technique widely exploited in biological studies and clinical applications. However, current FACS systems are quite complex, expensive, bulky, and pose potential sample contamination and biosafety issues due to the generation of aerosols in an open environment. Microfluidic technology capable of precise cell manipulation has great potential to reinvent and miniaturize conventional FACS systems. In this work, we demonstrate a benchtop scale FACS system that makes use of a highly focused traveling surface acoustic wave beam to sort out micron-sized particles and biological cells upon fluorescence interrogation at ∼kHz rates...

BK polyomavirus (BKPyV) is a human pathogen first isolated in 1971. BKPyV infection is ubiquitous in the human population, with over 80% of adults worldwide being seropositive for BKPyV. BKPyV infection is usually asymptomatic; however, BKPyV reactivation in immunosuppressed transplant patients causes two diseases, polyomavirus-associated nephropathy and hemorrhagic cystitis. To establish a successful infection in host cells, BKPyV must travel in retrograde transport vesicles to reach the nucleus. To make this happen, BKPyV requires the cooperation of host cell proteins...

BACKGROUND: Exoskeleton technology has potential benefits for wheelchair users' health and mobility. However, there are practical barriers to their everyday use as a mobility device. In particular, challenges related to travelling longer distances and transitioning between using a wheelchair and exoskeleton walking may present significant deterrents to regular exoskeleton use. In an effort to remove these barriers, a combined exoskeleton-wheelchair concept ('COMBO') has been proposed, which aims to achieve the benefits of both these mobility technologies...

A telepresence mobile robot is a remote-controlled, wheeled device with wireless internet connectivity for bidirectional audio, video and data transmission. In health care, a telepresence robot could be used to have a clinician or a caregiver assist seniors in their homes without having to travel to these locations. Many mobile telepresence robotic platforms have recently been introduced on the market, bringing mobility to telecommunication and vital sign monitoring at reasonable costs. What is missing for making them effective remote telepresence systems for home care assistance are capabilities specifically needed to assist the remote operator in controlling the robot and perceiving the environment through the robot's sensors or, in other words, minimizing cognitive load and maximizing situation awareness...

In this case report, we describe an unusual episode of bilateral submassive pulmonary embolism (PE) caused by a popliteal vein aneurysm (PVA). The development of PE stems from many risk factors including obesity (BMI³ 30 kg/m2), hypertension, cigarette smoking (greater than 25 cigarettes per day), increasing age, surgery, immobility, malignancy, and inherited thrombophilia. A PVA is a rare but significant cause of PE. A 28-year-old male presented to the emergency department with progressive shortness of breath...
