Published: August 2019

ABSTRACT:Background:We examined the impact of stroke severity and timing to inpatient rehabilitation admission on length of stay (LOS), functional gains, and discharge destination.Methods:Alberta inpatient stroke rehabilitation data between April 2013 and March 2017 were analyzed. We evaluated the impact of stroke severity, as measured by the Functional Independence Measure (FIM), on timing to inpatient rehabilitation, functional gains, LOS, and discharge destination. Further, we examined whether timing to inpatient rehabilitation impacted the latter three factors.Results:The 2404 adults were subcategorized as mild (1237), moderate (1031), or severe (136) based on FIM at inpatient rehabilitation admission. Length of time to rehabilitation admission was not significantly (p = 0.232) different between stroke severities. Mean length of time (days) to rehabilitation admission was 19.79 (20.3 SD) for mild, 27.7 (35.7 SD) for moderate, and 37.70 (56.8 SD) for severe stroke. Mean FIM change for mild (M = 16.3, 9.9 SD) differed significantly (p = 5.1 × 10–9) from moderate (M = 30.4, 16.4 SD) and severe (M = 31.0, 25.7 SD) stroke. The mean LOS for mild stroke (M = 41.3, 31.9 SD) was significantly (p = 5.1 × 10–9) different from moderate stroke (M = 86.8, 76.4 SD) and severe stroke (M = 126.1, 104.2 SD). Time to inpatient rehabilitation admission showed a small, significant impact on FIM change (p = 1.4 × 10–9, partial η2 0.022) and LOS (p = 1.1 × 10–19, partial η2 0.042). Shorter times to rehabilitation admission and mild stroke were associated with discharging home without needing homecare.Conclusion:Stroke severity has a significant impact on the conduct of inpatient rehabilitation. Yet, despite suggestions shortening timing to rehabilitation should improve outcomes, the impact on functional gains and rehabilitation LOS was small.

ABSTRACTObjective:The Centers for Disease Control and Prevention developed 15 National Public Health Emergency and Preparedness Response Capabilities (NPHPRCs) to serve as national standards for health-related core capabilities. The objective of this study is to determine the level of federal funding allocated for research related to NPHPRCs during 2008–2017.Methods:An online search of http://www.USAspending.gov was performed to identify federal awards, grants, contracts from 2008–2017 related to research associated with NPHPRCs. Inclusion criteria were identifiable as research and disaster-related; US-based; and specific reference to any of the NPHPRCs. A panel of 3 experts reviewed each entry for inclusion.Results:The search identified 15 278 transactions representing US $29.2 billion in awards. After exclusions, 93 entries were found to be related to NPHPRCs, averaging US $2 783 136 annually. Funding notably dropped to US $168 684 in 2010 and ceased entirely in 2016. Ten (67%) of NPHPRCs received funding. Eighty-percent of funding focused on 4 capabilities. Three federal agencies funded 80% of research. Sixteen (24%) of the 47 recipients received 80% of all funding.Conclusion:US federal investments in research and development related to NPHPRCs have been highly variable over the past decade. One-third of NPHPRCs receive no funding. There are notable gaps in funding, content, continuity, and scope of participation.

AbstractLittle is known about intimate partner abuse (IPA) among couples during pregnancy in Iran. This study aimed to compare the rates of IPA by pregnant women towards their husbands (perpetration), and women’s experience of IPA from their husbands (victimization) and determine the predictors of the two behaviours. The cross-sectional study was conducted on 525 pregnant women at 24–30 weeks of gestation visiting governmental health care centres/posts in Tabriz, Iran, in 2014. The study sample was selected using random cluster sampling. The Revised Conflict Tactics Scale (CTS2) was used to assess IPA perpetration and victimization. The McNemar test was employed to compare the prevalences of IPA perpetration and victimization, and adjusted logistic regression was utilized to determine the socio-demographic predictors of overall IPA perpetration and victimization. The overall rates of women’s reported abuse of their husbands (perpetration) and women’s experience of abuse from their husbands (victimization) were 70% and 67%, respectively, but the difference was not statistically significant (p=0.086). The prevalence of psychological aggression perpetrated by women towards their husbands was significantly higher than that experienced by the women from their husbands (65% vs 58%, p<0.001). The prevalences of sexual coercion (15% vs 30%) and injury (8% vs 16%) perpetrated by women on their husbands were significantly lower those they experienced by the women from their husbands (p<0.001). There was no statistically significant difference between the prevalence of perpetration of physical violence towards husbands by women (19%) and that experienced by women from their husbands (22%) (p=0.072). Women’s and husbands’ satisfaction with their own occupations were predictors of both perpetration and victimization of IPA. The observed high rates of IPA perpetration by, women and victimization of, women during pregnancy, and the significantly higher rate of violence towards women compared with that perpetrated by women, especially for sexual coercion and injury, require health policymakers and care providers to make serious efforts to identify such violence, and take appropriate measures to reduce it, during pregnancy in women in Iran.

Authors: Lou Z-C 
Published: August 2019

AbstractObjectiveTo review the origins of epistaxis in patients with unknown bleeding sites.MethodsThis consecutive case series included 26 patients with unknown bleeding sites previously considered to have posterior epistaxis. All patients had previously been examined endoscopically at least once, and were again examined with 30°, 45° and 70° endoscopes.ResultsThe bleeding site was at the: anterior end of the lateral wall of the inferior meatus in one patient (3.8 per cent); anterosuperior lateral wall of the nasal cavity in five patients (19.2 per cent); anterior nasal cavity roof in seven patients (26.9 per cent); anterosuperior part of the cartilaginous septum in nine patients (34.6 per cent); ostium pharyngeum tubae in two patients (7.7 per cent); and anterior nasal base in two patients (7.7 per cent). The morphology of the bleeding point showed: nasal mucosa ulceration in 1 patient, isolated primary telangiectasia in 3 patients, prominent vessels in 5 patients and capillary angioma in 17 patients.ConclusionEpistaxis originating from the anterosuperior nasal cavity and nasopharynx can be easily misdiagnosed as posterior epistaxis or unknown bleeding sites. Areas that should be considered as possible origins of epistaxis in cases with unknown bleeding sites were identified.

Published: August 2019

AbstractThe U.S. Department of Agriculture National Agricultural Statistics Survey (NASS) collects and publishes crop growth status and soil moisture conditions in major U.S. agricultural regions. The operationally produced weekly reports are based on survey information. The surveys are based on visual assessments and—in the case of soil moisture—report soil moisture levels in one of four categories (Very Short, Short, Adequate, and Surplus). In this study, we show that these reports have remarkable correspondence with the National Aeronautics and Space Administration Soil Moisture Active Passive (SMAP) Level‐4 Soil Moisture (L4SM) product. This consistency allows for combining the two different types of data to produce a value‐added assessment, which enables cropland soil moisture mapping and state‐level statistics. Moreover, it enables daily assessment rather than weekly. In this study classification thresholds are derived for L4SM by mapping cumulative distribution functions of L4SM surface and root zone SM to the categorical NASS SM conditions. The results show that, year over year, the SMAP cumulative SM distributions are consistent with the NASS SM conditions and, furthermore, that the temporal evolution of the SMAP‐derived thresholds is consistent with the seasonal crop growth cycles from year to year. The results signify that the SMAP SM retrievals are relatable to SM estimation conducted in agricultural crop land by land managers and farmers, which underlines the general applicability of the SMAP data.

AbstractSmall ponds—farm ponds, detention ponds, or impoundments below 0.01 km2—serve important human needs throughout most large river basins. Yet the role of small ponds in regional nutrient and sediment budgets is essentially unknown, currently making it impossible to evaluate their management potential to achieve water quality objectives. Here we used new hydrography data sets and found that small ponds, depending on their spatial position within both their local catchments and the larger river network, can dominate the retention of nitrogen, phosphorus, and sediment compared to rivers, lakes, and reservoirs. Over 300,000 small ponds are collectively responsible for 34%, 69%, and 12% of the mean annual retention of nitrogen, phosphorus, and sediment in the Northeastern United States, respectively, with a dominant influence in headwater catchments (54%, 85%, and 50%, respectively). Small ponds play a critical role among the many aquatic features in long‐term nutrient and sediment loading to downstream waters.
The Formation of Electron Heat Flux Over the Sunlit Quiet Polar Cap Ionosphere
Authors: Khazanov George V. , Sibeck David G. , Zesta Eftyhia 
Published: August 2019

AbstractWe consider a new mechanism for the thermal electron heat fluxes formation over the sunlit polar cap in the presence of the potential jumps that are created by the photoelectron escape along the open magnetic field lines. Photoelectrons traveling into the magnetosphere experience small Coulomb collisional scattering, and the low‐energy part of their spectra becomes trapped between the potential jump and upper ionosphere creating the thermal electron energy fluxes that support the formation of electron temperature at the ionospheric altitudes. This mechanism eliminates the need for the customary practice of assuming arbitrary electron heat fluxes at the upper ionospheric boundary in order to explain the measured electron temperature in the topside ionosphere.

Published: August 2019

AbstractMiniaturization is one of the important research directions of low frequency high power microwave sources. This paper presents a three-period coaxial slow-wave structure L-band high-power microwave source. Because the coaxial Quasi-TEM mode has no cut-off frequency, the radial size of the device can be reduced. At the same time, in order to reduce the transverse dimension, the coaxial extractor structure is introduced to realize the longitudinal mode selection and improve the conversion efficiency of the device. In simulation, the device obtains the microwave output with the central frequency of 1.53 GHz, the average power of 3.3 GW and the efficiency of 40%. By optimizing the scheme of electron beam collection, the phenomenon of pulse shortening is effectively suppressed. In the experiment, the device obtains the microwave output with the central frequency of 1.52 GHz, the average power of 3 GW, the efficiency of 33% and the pulse width of 40 ns.

AbstractControlled trunk motion is crucial for balance and stability during walking. Persons with lower extremity amputation often exhibit abnormal trunk motion, yet underlying mechanisms are not well understood nor have optimal clinical interventions been established. The aim of this work was to characterize associations between altered lower extremity joint moments and altered trunk dynamics in persons with unilateral, transtibial amputation (TTA). Full-body gait data were collected from 10 persons with TTA and 10 uninjured persons walking overground (~1.4 m/s). Experimentally-measured trunk angular accelerations were decomposed into constituent accelerations caused by net joint moments throughout the body using an induced acceleration analysis. Results showed persons with TTA had similar ankle moment magnitude relative to uninjured persons (P > 0.05), but greater trunk angular acceleration induced by the prosthetic ankle which acted to lean the trunk ipsilaterally (P = 0.003). Additionally, persons with TTA had a reduced knee extensor moment relative to uninjured persons (P < 0.001), resulting in lesser sagittal and frontal induced trunk angular accelerations (P < 0.001). These data indicate kinetic compensations at joints other than the lumbar and hip contribute to altered trunk dynamics in persons with a unilateral TTA. Findings may inform development of new clinical strategies to modify problematic trunk motion.

AbstractThere is a demand for ultra low-loss metal films with high-quality single crystals and perfect surface for nanophotonics and quantum information processing. Many researches are devoted to alternative materials, but silver is by far theoretically the most preferred low-loss material at optical and near-IR frequencies. Usually, epitaxial growth is used to deposit single-crystalline silver films, but they still suffer from unpredictable losses and well-known dewetting effect that strongly limits films quality. Here we report the two-step approach for e-beam evaporation of atomically smooth single-crystalline metal films. The proposed method is based on the thermodynamic control of film growth kinetics at atomic level, which allows depositing state-of-art metal films and overcoming the film-surface dewetting. Here we use it to deposit 35–100 nm thick single-crystalline silver films with the sub-100pm surface roughness and theoretically limited optical losses, considering an ideal material for ultrahigh-Q nanophotonic devices. Utilizing these films we experimentally estimate the contribution of grain boundaries, material purity, surface roughness and crystallinity to optical properties of metal films. We demonstrate our «SCULL» two-step approach for single-crystalline growth of silver, gold and aluminum films which open fundamentally new possibilities in nanophotonics, biotechnology and superconductive quantum technologies. We believe it could be readily adopted for the synthesis of other extremely low-loss single-crystalline metal films.

AbstractSeveral studies emphasized the potential of single and multiple transcranial random noise stimulation (tRNS) sessions to interfere with auditory cortical activity and to reduce tinnitus loudness. It was the objective of the present study to evaluate the use of high-frequency (hf) tRNS in a one-arm pilot study in patients with chronic tinnitus. Therefore, 30 patients received 10 sessions of high frequency tRNS (100-640 Hz; 2 mA; 20 minutes) over the bilateral temporal cortex. All patients had received rTMS treatment for their tinnitus at least 3 months before tRNS. Primary outcome was treatment response (tinnitus questionnaire reduction of ≥5 points). The trial was registered at clinicaltrials.gov (NCT01965028). Eight patients (27%) responded to tRNS. Exactly the same number of patients had responded before to rTMS, but there were only two “double responders” for both treatments. None of the secondary outcomes (tinnitus numeric rating scales, depressivity, and quality of life) was significant when results were corrected for multiple comparisons. tRNS treatment was accompanied by tolerable side effects but resulted in temporal increases in tinnitus loudness in 20% of the cases (2 drop-outs). Our trial showed that hf-tRNS is feasible for daily treatment in chronic tinnitus. However, summarizing low treatment response, increase of tinnitus loudness in 20% of patients and missing of any significant secondary outcome, the use of hf-tRNS as a general treatment for chronic tinnitus cannot be recommended at this stage. Differences in treatment responders between tRNS and rTMS highlight the need for individualized treatment procedures.

AbstractThe aim of this study was to identify the value of serum SHARP1 levels and Doppler of the uterine artery in singleton pregnancy at 11–13+6weeks for predicting preeclampsia. A prospective observational study was conducted in pregnant women at 11–13+6weeks of pregnancy who had antenatal care at King Chulalongkorn Memorial Hospital, Chulalongkorn University, Bangkok, Thailand, between January 2017 and January 2018. Serum SHARP1 measurement and transabdominal Doppler of the uterine artery were performed. The predictive values of these tests were determined. Data were obtained from 405 pregnant women. Thirty-five women had preeclampsia (8.6%), and six of these had early-onset preeclampsia (1.5%). Preeclamptic women had significantly lower serum SHARP1 levels than pregnant women without preeclampsia (3.6 ng/ml vs 4.7 ng/ml, p < 0.01). The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of serum SHARP1 levels of less than 3.89 ng/ml for predicting preeclampsia were 77.1%, 72.7%, 21.1% and 97.1%, respectively. For uterine artery Doppler, the sensitivity, specificity, PPV and NPV of the mean pulsatility index (PI) > 95thpercentile for predicting preeclampsia were 5.7%, 95.4%, 10.5% and 91.5%, respectively. For the combination of serum SHARP1 levels with a cutoff value of less than 3.89 ng/ml and a mean PI > 95thpercentile, the sensitivity, specificity, PPV and NPV were 77.1%, 70.3%, 19.7% and 97.0%, respectively. This study demonstrated that serum SHARP1 is a promising biomarker for predicting preeclampsia in the first trimester.

AbstractPrehabilitation is defined as the process of augmenting functional capacity before surgery in preparation for the postoperative phase. This study intends to assess the feasibility of conducting a preoperative intervention program in patients with lumbar spinal stenosis and to report on the piloting of the proposed intervention. Patients were allocated to a 6-week supervised preoperative rehabilitation program or a control group. The intervention included supervised exercise sessions aimed to improve strength, muscular endurance, and spinal stabilization. Outcomes were measured at baseline, 6 weeks later and again 6 weeks, 3 months and 6 months after surgery. Sixty-five percent of admissible participants agreed to take part in the study, of which 5% dropped out before the end of the intervention period. Eighty-eight percent of potential training sessions were delivered without adverse event. Improvements were seen in favour of the experimental group at the preoperative assessment for active ranges of motion, leg pain intensity, lumbar extensor muscle endurance and walking capacities. Results show that slight modifications to the choice of outcome measures would increase feasibility of the main study. The absence of adverse events coupled with positive changes seen in dependant outcome measures warrant the conduct of a full-scale trial assessing the effectiveness of the intervention.

Published: August 2019

AbstractFundamental challenge of imaging through a scattering media has been resolved by various approaches in the past two decades. Optical wavefront shaping technique is one such method in which one shapes the wavefront of light entering a scattering media using a wavefront shaper such that it cancels the scattering effect. It has been the most effective technique in focusing light inside a scattering media. Unfortunately, most of these techniques require direct access to the scattering medium or need to know the scattering properties of the medium beforehand. Through the novel scheme presented on this paper, both the illumination module and the detection are on the same side of the inspected object and the imaging process is a real time fast converging operation. We model the scattering medium being a biological tissue as a matrix having mathematical properties matched to the physical and biological aspects of the sample. In our adaptive optics scheme, we aim to estimate the scattering function and thus to encode the intensity of the illuminating laser light source using DMD (Digital Micromirror Device) with an inverse scattering function of the scattering medium, such that after passing its scattering function a focused beam is obtained. We optimize the pattern to be displayed on the DMD using Particle Swarm Algorithm (PSO) which eventually help in retrieving a 1D object hidden behind the media.
