Ninety-five percent limits of agreement for normalized differences approximated ±20%; 95% of the absolute differences for any pair of measurements were <4.6mm regardless of bodyweight and <3.5mm for dogs <15kg. Mitral valve disease did not appreciably affect these findings.

Left ventricular internal dimensions in dogs with and without cardiac disease measured from two-dimensional right parasternal short-axis images are interchangeable with those measured from M-mode images using the same view.

Here we report on the effectiveness of a fluency shaping treatment for 6- to 9-year-old children. The main treatment component is the reinforcement of soft voice onsets. An intensive in-patient group treatment phase lasts 6 days, followed by a 6-month maintenance phase with 3 in-patient weekend group refresher courses. Child and a parent participate together in various treatment activities. In this controlled intervention study (waitlist control, intention-to-treat design) assessments were performed before treatment (T1), 4 weeks after the intensive phase (T2), at the end of the maintenance phase (T3), and 1 year later (T4). Participants were 119 children (108 boys, 11 girls, age 5.5‑10.4 years). Control conditions included a subgroup with delayed treatment (N=25) as well as the assessment of complexity of utterances, inter-rater reliability, and speech naturalness. From before treatment to 1-year follow-up, percent stuttered syllables and OASES-S (Overall Assessment of the Speaker’s Experience with Stuttering – School-age) scores decreased with large effect size. Speech naturalness improved during this period but did not reach the level of non-stuttering children. Complexity of utterances increased during the intensive phase, but only temporarily. Twenty children (16.8 %, including dropouts) showed no demonstrable treatment benefit. Fluency shaping treatment can be effectively applied to young school children. It is assumed that parental support, group therapy, intensive treatment, and regular exercises at home are essential.A pneumonia outbreak of unknown aetiology emerged in Wuhan, China in December 2019. The causative organism was identified on 7th January 2020 as a novel coronavirus (nCoV or 2019-nCoV), later renamed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The resulting coronavirus disease (COVID-19) has infected over 88 million individuals, resulted in over 1.9 million deaths, and has led to an unprecedented impact on research activities worldwide. Extraordinary challenges have also been imposed on medical and surgical trainees following redeployment to full-time clinical duties. Moreover, the introduction of travel restrictions and strict lockdown measures have forced the closure of many institutions and laboratories working on research unrelated to the pandemic. The lockdown has similarly stifled supply chains and slowed research and development endeavours, whilst research charities have endured significant financial strains that have since reshaped the allocation and availability of funds. However, worldwide scientific adaptation to the COVID-19 pandemic has been observed through unprecedented levels of international collaboration alongside the uprise of remote telecommunication platforms. Although the long-term consequence of the COVID-19 pandemic on research and academic training is difficult to ascertain, the current crises will inevitably shape working and teaching patterns for years to come. To this end, we provide a comprehensive and critical evaluation of the impact of COVID-19 on scientific research and funding, as well as academic medical and surgical training.

Many risk factors are associated with rupture of intracranial aneurysm. However, the prognostic effects hemodynamic factors on intracranial aneurysm rupture remains poorly understood. A meta-analysis was performed based on contemporary studies to evaluate the prognostic effect of hemodynamic parameters on rupture of intracranial aneurysm.

The Cochrane Library, PubMed, Embase, and Web of Science were searched for cohort studies that analyzed hemodynamic parameters for intracranial aneurysm rupture prior to May 1, 2020. The standardized mean difference (SMD) and odds ratio (OR) with 95% confidence interval (CI) were calculated to assess the effect of individual hemodynamic parameters on intracranial aneurysm rupture. The primary outcomes were difference in wall shear stress (WSS), oscillatory shear index (OSI) and low shear index (LSA) between ruptured and unruptured intracranial aneurysm. Two reviewers independently assessed the quality of the trials and the associated data. momordinIc All statistical analyses were pneurysm. The roles of other hemodynamic parameters and risk factors for intracranial aneurysm rupture need further assessments in future.

This meta-analysis identified WSS, OSI and LSA% as influential hemodynamic parameters on rupture of intracranial aneurysm. The roles of other hemodynamic parameters and risk factors for intracranial aneurysm rupture need further assessments in future.

To evaluate the relationship between visual function and a five-year history of motor vehicle collision rates in older adults. Motion perception impairment was explored as a risk factor for motor vehicle collisions for the first time in this study.

Participants were licensed drivers ≥70 years old enrolled in the Alabama VIP Older Driver Study who underwent functional assessments for motion perception, distance visual acuity, contrast sensitivity, visual field sensitivity, and visual processing speed. Participants were recruited based on their being patients in an ophthalmology clinic in the year prior to enrollment or had participated in an earlier driving study. Crash reports were obtained from the Alabama Law Enforcement Agency for the 5 years prior to enrollment and mileage estimated using the Driving Habits Questionnaire. Crude and age-adjusted rate ratios (RRs) and 95 % confidence intervals (95 % CIs) were calculated using Poisson regression.

159 participants enrolled with a mean age of 79 years. The age-adjusted crash rate was higher among those with worse motion perception (RR 2.
