ObjectivesTo assess physical activity (PA), mental health and well-being of adults in the United Kingdom (UK), Ireland, New Zealand Australia during initial stages National governments' Coronavirus disease (COVID-19) containment responses.DesignObservational, cross-sectional.MethodsAn online survey was disseminated to (n = 8,425; 44.5 ± 14.8y) residing UK, within first 2-6 weeks government-mandated COVID-19 restrictions. Main outcome measures included: Stages Change scale for exercise...
We conducted a prospective, randomized trial to compare the safety and effectiveness of A-V Impulse System foot pump with that low-molecular-weight heparin for reducing prevalence deep-vein thrombosis after total hip replacement. Of 290 patients who were have primary replacement, 143 receive enoxaparin (forty milligrams daily) seven days operation 147, use days. The outcome measure was thrombosis, as determined by venography on sixth, seventh, or eighth postoperative day. Secondary measures...
OBJECTIVES To present the results of a minimally invasive treatment symptomatic simple renal cysts, and to propose an algorithm for their management. PATIENTS AND METHODS Seventeen patients presenting with suspected cysts were referred trial aspiration; 16 presented loin pain one flank mass. If cyst symptoms recurred after temporary response, they managed by re‐aspiration sclerotherapy using 95% ethanol, or laparoscopic de‐roofing cyst. RESULTS Of 17 referred, failed respond aspiration was...
Physical activity (PA) participation was substantially reduced at the start of COVID-19 pandemic. The purpose this study to assess association between PA, mental health, and wellbeing during following easing restrictions in United Kingdom (UK) New Zealand (NZ). In study, 3363 adults completed online surveys within 2-6 weeks initial (April/May 2020) once human movement had been eased. Outcome measures included International Activity Questionnaire Short-Form, Depression Anxiety Stress Scale-9...
Renal oncocytomas are classified as benign renal neoplasms in the 2004 World Health Organization classification of tumours .1 Cases metastatic have been documented,2–4 but subsequent reports identified subtypes having similar histological morphology malignant potential. These either eosinophilic variants cell carcinoma (RCC) or chromophobe carcinomas. Differentiating these from has proved to be difficult and relies on a combination morphology, immunohistochemistry electron microscopy. There...
ABSTRACT Objectives To assess how the early stages of National governments Coronavirus disease (COVID-19) containment strategies impacted upon physical activity, mental health and well-being adults in UK, Ireland, New Zealand Australia Design Observational, cross-sectional Setting Online survey disseminated within first 2-6 weeks government mandated COVID-19 restrictions Participants Adults (n = 8,425; 44.5 ± 14.8 y), ≥ 18 y who were residing surveyed countries Main outcome measures Stages...
In previous randomised clinical trials of thromboprophylaxis after total hip replacement, low-molecular-weight heparin has been given for an arbitrary 7 to 14 days. The risk factors are mainly perioperative and it is possible that a shorter course may be adequate. We assessed the safety effectiveness three-day course. 156 primary THR patients randomisation either control group or receive enoxaparin at 12 hours preoperatively 36 postoperatively. Thrombosis was diagnosed by routine venography....
Patients who undergo total knee replacement (TKR)are at high risk of venous thromboembolism. Low-molecular-weight heparins (LMWH) are the most suitable chemical prophylactic agents but there some uncertainties about their safety and effectiveness. The foot pump offers an alternative. We randomised 229 patients undergoing primary, unilateral TKR to receive either A-V Impulse or enoxaparin, a LMWH. Ascending venography was undertaken between sixth eighth postoperative day in 188 without...
Abstract This study compares the results of a computerized strain-gauge plethysmograph with ascending lower limb venography in 94 patients clinical deep venous thrombosis, and 121 asymptomatic legs being screened after total hip replacement. In symptomatic patients, plethysmography had sensitivity 100%, an accuracy 73%, specificity 64% negative predictive value 100% for thrombosis above popliteal confluence. figures were 38.1%, 55.4%, 60.0% 81.1% respectively. Computerized is safe,...
Abstract This study compares the results of impedance plethysmography with lower limb venography in 68 patients referred for investigation clinical deep vein thrombosis, and ventilation/perfusion isotope scans 125 suspected pulmonary embolism. Impedance had a sensitivity 100% specificity 61% detection thromboses involving popliteal or more proximal veins (30 patients), but 90% 68% thrombosis at any level, because low isolated calf (60% 10 patients). It is non-invasive, portable low-cost...
This study examined the short-term reproducibility of non-invasive estimates central and peripheral blood pressure markers systolic loading (augmentation index [AIx; a measure loading] AIx75 [AIx standardised to 75 b·min-1 heart rate]) effect posture fasting state on these variables in patients with acute stroke.Twenty-two stroke (72 ± 10y) had measured using SphygmoCor XCEL supine seated postures whilst fasted non-fasted.Acceptable (ICC >0.75) was reported for all conditions = 0.77-0.90)...
Background and objectives: As survival rates after incident stroke increase, the burden caused by secondary pressure placed on rehabilitation centers also rises. Lifestyle interventions have potential to drive secondary-prevention treatments. Low-intensity interventions, such as heel raises, may offer a simple method of improving cardiovascular health cognitive ability in chronic stroke. Here we present protocol which attempts determine whether raise training program can improve markers...
Methods All images were obtained using a double headed gamma camera, Butterworth filter and 8 frame/s acquisition for gated SPECT. patients reported to have normal perfusion images, quantified by Myoquant index of less than 1 ejection fraction. patient data processed QGS Multidim volume assessment software packages. Results Forty (24 female, 16 male, average age 56.2 years) included. The EDV at rest was 73.0 ml (range 26–119, SD 22.2 ml) with 138.1 (48–242, 40.2) software. post-stress...
