RESUMEN
BACKGROUND: There is a change in the position of the remaining anatomical structures of the lower urinary tract system following radical prostatectomy. The aims of this investigation were to describe three novel methods used to measure the displacement of i) the vesico-urethral junction (VUJ), proximal membranous urethra (PMU) and anorectal junction (ARJ) and ii) the VUJ angle of displacement in men following radical prostatectomy and determine their intra- and interrater reliability. METHODS: Retrospective comparative measurement of twenty pre- and postoperative MRI scans was undertaken by one observer on two separate occasions and on one occasion by another observer. Three standardized midsagittal pelvimetry reference lines were used to describe three X, Y axis measurement systems. The displacement (mm) of the VUJ, PMU and ARJ, and the angle of displacement (degrees) of the VUJ was measured for each of the three methods. Interrater reliability of VUJ, PMU and ARJ displacement and the VUJ angle of displacement measurements was assessed using a two-way mixed-effects agreement intra-class correlation coefficient (ICC) with 95% confidence intervals (CI). Test-retest (intrarater) reliability was calculated using a two-way random effects consistency ICC with 95% CI for all displacement measures of the VUJ, PMU and ARJ for one observer between two days. RESULTS: The pubococcygeal line (PCL) axis measurement system demonstrated good to excellent intrarater and interrater reliability (ICC 95% interval lower bound > 0.75) for the VUJ and PMU displacement and the VUJ angle of displacement measurements. Other measurement systems were less reliable and more variable. CONCLUSIONS: In this sample of 20 Korean patients with median prostate volume 27.5 mL and maximum volume 70 mL, the measurement methodology using the PCL consistently demonstrated good to excellent reliability and the lowest variability for the measurement of the displacement of the VUJ and PMU and the VUJ angle of displacement. The PCL methodology is recommended as the method of choice. Further studies should validate these results in patients with large prostate volumes.

AIMS: Pelvic floor muscle training for patients having radical prostatectomy promotes contraction of these muscles in anticipation of activities that may provoke urine leakage. The aims of this study were: to determine the contribution of the individual activities comprising a standardised 1-hour pad test (1HPT) to overall urine leakage early after radical prostatectomy; and to investigate relationships between the 1HPT, 24-hour pad test (24HPT) and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) early after radical prostatectomy. METHODS: A prospective analysis of patients having radical prostatectomy and receiving pelvic floor muscle training (n = 33). Participants completed the 1HPT, 24HPT and ICIQ-SF at 3 and 6 weeks postoperatively. Participants wore a separate, pre-weighed continence pad for each of the seven activities comprising the 1HPT; pads were weighed separately and together to calculate activity-related and overall urine leakage. RESULTS: Walking at a comfortable speed and drinking while sitting were the two activities contributing most to overall urine leakage, albeit these activities also comprised 75% of 1HPT time. All component activities contributed a minimum 7 ± 5% of overall urine leakage. There were significant and strong to very strong correlations between all of the 1HPT, 24HPT, and ICIQ-SF at 3 weeks postoperatively. There were significant decreases in 24HPT (P = 0.032) and ICIQ-SF (P = 0.001) but no significant change in 1HPT from 3 to 6 weeks postoperatively. CONCLUSIONS: Pelvic floor muscle training should include contraction of these muscles in sedentary and walking postures. The 1HPT correlates well with the 24HPT, but may not be sensitive to early postoperative improvements in urinary leakage.

OBJECTIVE: Prostate cancer is the most commonly diagnosed cancer among men in the USA, and radical prostatectomy (RP) is the primary surgical treatment option. With an increasing number of men undergoing RP and surviving prostate cancer, clinical management strategies have broadened to improve the preoperative and postoperative patient experience and minimize treatment-related functional consequences. Urinary incontinence is a predictable functional consequence of RP. Recent reviews recommend preoperative and postoperative physical therapist services as the standard of care for men undergoing RP to decrease the severity of urinary incontinence and improve patients' quality of life. Despite compelling evidence, the routine provision of physical therapist services preoperatively and postoperatively for men undergoing RP is limited. The purpose of this case report is to describe the implementation of preoperative and postoperative physical therapist services for men undergoing RP in a US health care system using the knowledge-to-action process and the Consolidated Framework for Implementation Research frameworks. CASE DESCRIPTION: The implementation process included 4 steps: (1) development of a preoperative and postoperative physical therapist services program; (2) identification of barriers and enablers for implementation; (3) implementation of the program; and (4) evaluation of the effectiveness of the implemented program. RESULTS: Outcomes from the implementation of a physical therapist services program for men undergoing RP included lower urinary incontinence rates, improved patient satisfaction, and increased physical therapist utilization. CONCLUSION: This case report documents the implementation of physical therapist services for men undergoing RP. The use of implementation frameworks enabled the identification of unique enablers, barriers, and strategies for the implementation of physical therapist services for men undergoing RP. IMPACT: Implementing preoperative and postoperative physical therapist services for men undergoing RP improves patient outcomes. The implementation process and outcomes can be considered by other health care systems when developing preoperative and postoperative physical therapist services for men undergoing RP.

We investigated the impact of distance covered in the six-minute walk test (6mWT) before being discharged from the hospital after cardiac surgery on the risk of all-cause mortality. Our study included 1127 patients who underwent cardiac surgery and then took part in a standardised physiotherapist-supervised inpatient rehabilitation programme during 2007-2017. The percentage of the predicted 6mWT distance, and the lower limit of normal distance was calculated based on individual patients' age, sex, and body mass index. We used Cox regression with adjustment for confounders to determine multivariable-adjusted hazard ratios (HRs) for mortality. Over a median follow-up period of 6.4 (IQR: 3.5-9.2) years, 15% (n = 169) patients died. We observed a strong and independent inverse association between 6mWT distance and mortality, with every 10 m increase in distance associated to a 4% reduction in mortality (HR: 0.96, 95% CI 0.94-0.98, P < 0.001). Those in the top tertile for predicted 6mWT performance had a 49% reduced risk of mortality (HR: 0.51, 95% CI 0.33-0.79) compared to those in the bottom tertile. Patients who met or exceeded the minimum normal 6mWT distance had 36% lower mortality risk (HR: 0.64, 95% CI 0.45-0.92) compared to those who did not meet this benchmark. Subgroup analysis showed that combined CABG and valve surgery patients walked less in the 6mWT compared to those undergoing isolated CABG or valve surgeries, with a significant association between 6mWT and mortality observed in the isolated procedure groups only. In conclusion, the longer the distance covered in the 6mWT before leaving the hospital, the lower the risk of mortality.

BACKGROUND: Higher physical activity levels are continence-protective in non-prostate cancer populations. Primary aims of this study were to investigate changes in physical activity levels over the perioperative period in patients having radical prostatectomy, and relationships between perioperative physical activity levels and post-prostatectomy urinary incontinence. METHODS: A prospective analysis of patients having radical prostatectomy and receiving perioperative physiotherapy including pelvic floor muscle training and physical activity prescription (n = 33). Physical activity levels were measured using the International Physical Activity Questionnaire and/or the SenseWear Pro3 Armband at four timepoints: before preoperative physiotherapy, the week before surgery, and 3 and 6 weeks postoperatively. Urinary incontinence was measured at 3 and 6 weeks postoperatively using a 24-hour pad test and the International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form (ICIQ). RESULTS: Physical activity levels changed significantly over the perioperative period (p < 0.001). At 6 weeks postoperatively, physical activity levels did not differ significantly from baseline (p = 0.181), but remained significantly lower than the week before surgery (p = 0.002). There was no significant interaction effect between preoperative physical activity category and time on the 24-hour pad test (p = 0.726) or ICIQ (p = 0.608). Nor were there any significant correlations between physical activity levels and the 24-hour pad test and ICIQ at 3 or 6 weeks postoperatively. CONCLUSIONS: This study provides novel data on perioperative physical activity levels for patients having radical prostatectomy. There was no relationship between perioperative physical activity levels and post-prostatectomy urinary incontinence, although participants had high overall preoperative physical activity levels and low overall urinary incontinence.

OBJECTIVES: Urinary incontinence is a predictable sequela of radical retropubic prostatectomy, and is most severe in the early postoperative phase. The present study aimed to evaluate the effect of a physiotherapist-guided pelvic floor muscle training program, commenced preoperatively, on the severity and duration of urinary continence after radical retropubic prostatectomy. METHODS: A retrospective analysis of men undergoing radical retropubic prostatectomy by one high-volume surgeon (n = 284) was carried out. The intervention group received physiotherapist-guided pelvic floor muscle training from 4 weeks preoperatively (n = 152), whereas the control group was provided with verbal instruction on pelvic floor muscle exercise by the surgeon alone (n = 132). Postoperatively, all patients received physiotherapist-guided pelvic floor muscle training. The primary outcome measure was 24-h pad weight at 6 weeks and 3 months postoperatively. Secondary outcome measures were the percentage of patients experiencing severe urinary incontinence, and patient-reported time to one and zero pad usage daily. RESULTS: At 6 weeks postoperatively, the 24-h pad weight was significantly lower (9 g vs 17 g, P < 0.001) for the intervention group, which also showed less severe urinary incontinence (24-h pad weight >50 g; 8/152 patients vs 33/132 patients, P < 0.01). There was no significant difference between groups in the 24-h pad weight at 3 months (P = 0.18). Patient-reported time to one and zero pad usage was significantly less for the intervention group (P < 0.05). Multivariate Cox regression showed that preoperative physiotherapist-guided pelvic floor muscle training reduced time to continence (1 pad usage daily) by 28% (P < 0.05). CONCLUSIONS: A physiotherapist-guided pelvic floor muscle training program, commenced 4 weeks preoperatively, significantly reduces the duration and severity of early urinary incontinence after radical retropubic prostatectomy.

BACKGROUND: Orthostatic intolerance (OI)-type events following hip and knee arthroplasty increase the risk of falls, hospital length of stay, and health-care costs. There is a limited understanding of the incidence of and risk factors for OI-type events in patients during the acute hospital stay. Our aim was to systematically review the incidence of and risk factors for OI-type events during the acute hospital stay following hip and knee arthroplasty. METHODS: A systematic review and meta-analysis of studies that investigated the incidence of and risk factors for OI-type events was undertaken. A comprehensive search was performed in MEDLINE, Embase, and CINAHL from their inception to October 2021. The methodological quality of identified studies was assessed using the modified version of the Quality in Prognosis Studies (QUIPS) tool. RESULTS: Twenty-one studies (14,055 patients) were included. The incidence was 2% to 52% for an OI event, 1% to 46% for orthostatic hypotension, and 0% to 18% for syncope/vasovagal events. Two studies reported female sex, high peak pain levels (>5 out of 10) during mobilization, postoperative use of gabapentin, and the absence of postoperative intravenous dexamethasone as risk factors. There was no consensus on the definition and assessment of an OI-type event. CONCLUSIONS: OI-type events are common during the acute hospital stay following hip and knee arthroplasty, and 4 risk factors have been reported for OI-type events. High-quality prospective cohort studies are required to systematically and reliably determine the incidence of and risk factors for OI-type events. LEVEL OF EVIDENCE: Prognostic Level IV.

CONTEXT: Prostate cancer (PCa) is one of the most common cancers worldwide. Understanding the epidemiology and risk factors of the disease is paramount to improve primary and secondary prevention strategies. OBJECTIVE: To systematically review and summarize the current evidence on the descriptive epidemiology, large screening studies, diagnostic techniques, and risk factors of PCa. EVIDENCE ACQUISITION: PCa incidence and mortality rates for 2020 were obtained from the GLOBOCAN database of the International Agency for Research on Cancer. A systematic search was performed in July 2022 using PubMed/MEDLINE and EMBASE biomedical databases. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines and was registered in PROSPERO (CRD42022359728). EVIDENCE SYNTHESIS: Globally, PCa is the second most common cancer, with the highest incidence in North and South America, Europe, Australia, and the Caribbean. Risk factors include age, family history, and genetic predisposition. Additional factors may include smoking, diet, physical activity, specific medications, and occupational factors. As PCa screening has become more accepted, newer approaches such as magnetic resonance imaging (MRI) and biomarkers have been implemented to identify patients who are likely to harbor significant tumors. Limitations of this review include the evidence being derived from meta-analyses of mostly retrospective studies. CONCLUSIONS: PCa remains the second most common cancer among men worldwide. PCa screening is gaining acceptance and will likely reduce PCa mortality at the cost of overdiagnosis and overtreatment. Increasing use of MRI and biomarkers for the detection of PCa may mitigate some of the negative consequences of screening. PATIENT SUMMARY: Prostate cancer (PCa) remains the second most common cancer among men, and screening for PCa is likely to increase in the future. Improved diagnostic techniques can help reduce the number of men who need to be diagnosed and treated to save one life. Avoidable risk factors for PCa may include factors such as smoking, diet, physical activity, specific medications, and certain occupations.

INTRODUCTION: Erectile dysfunction is a common consequence after radical prostatectomy (RP) affecting psychosocial well-being and quality of life. As the RP surgical technique is complex, it is reasonable to propose that the experience of the surgeon could influence the postoperative erectile function (EF) outcomes. OBJECTIVE: To undertake a systematic review to investigate whether the surgeon's experience affects the patient's ability to regain EF after RP. METHODS: A comprehensive literature search was performed in April 2020 using Medline, Embase, CINAHL, and psychINFO. All relevant English research studies investigating the topic area were included, with experience being defined as both cumulative RP and average RP annual surgical caseload. RESULTS: The main outcome measure is EF after RP stratified by surgeon experience (annual case load or cumulative case volume). Ten case-control studies published between 2003 and 2020 met the inclusion criteria and were chosen for this systematic review. The included studies consisted of both single- and multiple-surgeon studies. Studies that compared annual RP caseload per surgeon demonstrated a difference between high- and low-volume surgeons, only when high volume was >25 RP cases/year. In the studies reporting cumulative case volume (learning curve), differences between high volume and low volume were only identified when the total case volume was approximately 1000 RP cases. Studies with low-volume cases (approximately 100) did not show any differences in EF outcomes. CONCLUSION: The studies examined in our systematic review demonstrate that an annual surgeon caseload of >25 RP cases per year or total cumulative experience of >1000 RP cases results in better EF outcomes after RP.

BACKGROUND: Urinary incontinence (UI) is a common complication following radical prostatectomy (RP). Prolonged UI has a substantial impact on quality of life and psychosocial well-being. As the RP technique is complex, it is reasonable to propose that surgeon experience could affect post-operative continence recovery outcomes. This study aimed to systematically evaluate evidence regarding a surgeon's experience and continence recovery after RP. METHODS: A comprehensive search of the literature was performed in April 2020 using the Medline, Embase, CINAHL and psychINFO electronic databases according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. All English language studies investigating UI following RP, stratified by surgeon experience, were included. Surgeon experience was defined as average annual case load or volume. RESULTS: Thirteen studies published between 2003 and 2020 met the inclusion criteria and were included in our systematic review. Three prospective and 10 retrospective cohort studies included a total of 47 316 patients undergoing RP via open, laparoscopic or robotic-assisted procedures. Heterogeneity in the definition of surgeon experience and UI did not allow a meta-analysis. The majority of studies reported that surgeons with higher surgical volumes achieved better continence recovery rates at the early (6-week), 3-month, 6-month and later (≥12-month) time points. Most studies where a high surgical volume was defined as >50 cases/year demonstrated a significant difference in continence outcomes. CONCLUSION: Better urinary continence recovery results can be expected by patients who undergo RP performed by a surgeon with greater experience. An annual surgical case load of >50 cases/year results in improved continence recovery outcomes following RP.

Urinary incontinence is a common and predictable consequence among men with localized prostate cancer who have undergone radical prostatectomy. Despite advances in the surgical technique, urinary continence recovery time remains variable. A range of surgical and patient-related risk factors contributing to urinary incontinence after radical prostatectomy have been described, including age, BMI, membranous urethral length and urethral sphincter insufficiency. Physical activity interventions incorporating aerobic exercise, resistance training and pelvic floor muscle training programmes can positively influence the return to continence in men after radical prostatectomy. Traditional approaches to improving urinary continence after radical prostatectomy have typically focused on interventions delivered during the postoperative period (rehabilitation). However, the limited efficacy of these postoperative approaches has led to a shift from the traditional reactive model of care to more comprehensive interventions incorporating exercise-based programmes that begin in the preoperative period (prehabilitation) and continue after surgery. Comprehensive prehabilitation interventions include appropriately prescribed aerobic exercise, resistance training and specific pelvic floor muscle instruction and exercise training programmes. Transperineal ultrasonography is a non-invasive and validated method for the visualization of the action of the pelvic floor musculature, providing real-time visual biofeedback to the patient during specific pelvic floor muscle instruction and training. Importantly, the waiting time before surgery can be used for the delivery of comprehensive prehabilitation exercise-based interventions to increase patient preparedness in the lead-up to surgery and optimize continence and health-related quality-of-life outcomes following radical prostatectomy.

PURPOSE: Continence assessment is an essential component of follow-up after radical prostatectomy (RP). Several methods exist to assess the severity of urinary incontinence (UI). Our study examined the relationship and degree of agreement between International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) scores and the number of pads used in a 24-hour period in the assessment of UI following RP. METHODS: Continence was prospectively assessed in 746 men from a Spanish urology clinic 12 months after RP using the ICIQ-SF and pad usage. The relationship between ICIQ-SF scores and pad usage was assessed using Spearman rank correlation coefficients. The Jonckheere-Terpstra trend test was used to determine whether the ICIQ-SF score and the component question scores increased with increasing pad usage. The Bonferroni-corrected pairwise Wilcoxon rank-sum test was used to determine which pairs of pad usage levels differed. The weighted kappa was used to evaluate the agreement between pad usage levels and ICIQ-SF questions. RESULTS: The continence rate was 82% using the "no pad usage" definition of continence versus 78% using the definition of an ICIQ-SF score of 0 (P<0.001). Strong positive correlations were observed between the number of pads and the ICIQ-SF total and component question scores (rs>0.85, P<0.001). The ICIQ-SF total and component question scores increased significantly with increasing pad usage (P<0.001). The ICIQ-SF scores (P<0.018) for all pairs of pad usage levels (0, 1, 2, or 3 or more) differed significantly. The agreement between the ICIQ-SF leakage amount question and pad usage was very good (rs=0.861, P<0.001). CONCLUSION: At 12 months post-RP, 24-hour pad usage was closely correlated with ICIQ-SF, although the continence rate differed depending on the definition used. Higher levels of pad usage were associated with higher questionnaire scores, more leakage, and poor quality of life (interference with everyday life).
RESUMEN
Purpose: To develop a cadaver model for the assessment of a male transobturator male sling (retrourethral transobturator sling [RTS], AdVance™; Boston Scientific, USA) to investigate its effect on a simulated abdominal and retrograde leak point pressures (ALPP, RLPP) and the urethral pressure profile (UPP). Materials and Methods: Three fresh frozen human male cadaver specimens were obtained. A suprapubic tube was inserted into the bladder and connected to a digital manometer to measure bladder pressure. Manual suprapubic pressure was then applied to generate an increase in intraabdominal pressure and measure a simulated ALPP. Subsequent measurements of RLPP and UPP were recorded. All measurements were undertaken prior to and following insertion of a RTS. Results: The placement of the RTS consistently increased the simulated ALPP for all three cadaver specimens when compared to baseline measures. No leaks occurred at simulated ALPP's of 170 cm H2O for specimen 1, 160 cm H2O for specimen 2, and 170 cm H2O for specimen 3. There was minimal or no change in the RLPP's and UPP's following insertion of the RTS when compared to respective baseline. Conclusions: A model using fresh unfixed cadavers that incorporates a simulated measurement of ALPP is feasible for male stress urinary incontinence surgical intervention investigations.

BACKGROUND: Direct lateral interbody fusion (DLIF) mitigates many of the vascular complications and bony resections associated with other interbody fusion techniques. However, there are concerns regarding postoperative neural complications and that indirect decompression of the foramen has not been consistently demonstrated. This study prospectively assessed the clinical and radiological outcomes and the complication rates of the DLIF approach. METHODS: A prospective review was conducted of the first 50 consecutive DLIF cases of a single neurosurgeon between 2010 and 2014. Clinical outcomes were assessed using Visual Analogue Scale (VAS), Oswestry Disability Index (ODI) and Roland Morris Disability Questionnaire (RMDQ) surveys. Radiological outcomes, including spondylolisthesis, disc height, local disc angle, lumbar lordosis and foraminal height and width, were measured using Surgimap Spine software at the preoperative, 6 weeks, 6 months, and 12 months postoperative follow-up. Complication rates were also reported. RESULTS: A total of 50 patients (84 levels) were treated with DLIF. The mean patient age was 68.2±9.8 years and 62.0% were female. At latest follow-up, mean VAS pain score improved from 7.7±1.5 to 1.9±0.9 (P<0.0001), mean ODI improved from 42.1±14.5 to 16.9±6.7 (P<0.0001) and mean RMDQ score improved from 12.1±5.2 to 6.2±4.7 (P<0.0001). Mean spondylolisthesis reduced from 7.5%±6.5% to 1.3%±1.1% at 6 weeks (P<0.0001), 0.95%±0.74% at 6 months (P<0.0001) and recurred to 1.9%±1.7% at 12 months postoperatively (P=0.0006). Mean anterior disc height improved from 7.3±3.2 to 11.6±2.5 mm at 6 weeks (P<0.0001), 12.2±3.3 mm at 6 months (P<0.0001) and 9.8±2.1 mm at 12 months (P=0.0032) postoperatively. Mean posterior disc height improved from 4.4±2.0 to 6.8±2.1 mm at 6 weeks (P<0.0001), 6.6±2.5 mm at 6 months (P=0.0003), and 5.9±1.4 mm at 12 months (P=0.0039) postoperatively. Mean local disc angle improved from 7.0°±3.7° to 9.2°±3.3° at 6 weeks (P=0.0072), 10.4°±3.9° at 6 months (P=0.0013) and 8.2°±2.9° at 12 months (P=0.2487) postoperatively. No significant postoperative changes in lumbar lordosis were observed. Mean foraminal height improved from 18.3±3.5 to 21.5±3.9 mm at 6 weeks (P=0.0004), 20.6±3.4 mm at 6 months (P=0.0266), and 18.7±1.9 mm at 12 months (P=0.8021) postoperatively. Mean foraminal width improved from 7.9±2.0 to 10.2±2.8 mm at 6 weeks (P=0.0001), 9.4±2.6 mm at 6 months (P=0.0219) and 8.3±1.6 mm at 12 months (P=0.5734) postoperatively. Fusion rate at 6 and 12 months was 62.2% and 89.2%, respectively. A total of 6 patients (12%) had postoperative complications. Three patients (6%) had pain-related psoas muscle weakness and 3 patients (6%) had sensory neural complications that had resolved entirely by 8 and 16 weeks postoperatively, respectively. CONCLUSIONS: The study provides encouraging short and medium-term clinical and radiological results for DLIF. In this patient series, there was a low complication rate with no permanent neural injury reported.
RESUMEN
Cardiac surgery via median sternotomy is performed in over 1 million patients per year worldwide. Despite evidence, sternal precautions in the form of restricted arm and trunk activity are routinely prescribed to patients following surgery to prevent sternal complications. Sternal precautions may exacerbate loss of independence and prevent patients from returning home directly after hospital discharge. In addition, immobility and deconditioning associated with restricting physical activity potentially contribute to the negative sequelae of median sternotomy on patient symptoms, physical and psychosocial function, and quality of life. Interpreting the clinical impact of sternal precautions is challenging due to inconsistent definitions and applications globally. Following median sternotomy, typical guidelines involve limiting arm movement during loaded lifting, pushing, and pulling for 6 to 8 weeks. This perspective paper proposes that there is robust evidence to support early implementation of upper body activity and exercise in patients recovering from median sternotomy while minimizing risk of complications. A clinical paradigm shift is encouraged, one that encourages a greater amount of controlled upper body activity, albeit modified in some situations, and less restrictive sternal precautions. Early screening for sternal complication risk factors and instability followed by individualized progressive functional activity and upper body therapeutic exercise is likely to promote optimal and timely patient recovery. Substantial research documenting current clinical practice of sternal precautions, early physical therapy, and cardiac rehabilitation provides support and the context for understanding why a less restrictive and more active plan of care is warranted and recommended for patients following a median sternotomy.

BACKGROUND: This study aimed to determine whether a structured, inpatient (or Phase 1 cardiac rehabilitation), physiotherapy-supervised walking program, with or without musculoskeletal and respiratory exercises, might improve walking capacity and other parameters for patients undergoing coronary artery bypass graft surgery (CABG). METHODS: Ninety-three patients awaiting first-time CABG over a 12-month period were randomised to one of three post-operative physiotherapy regimens: 'standard intervention', consisting of gentle mobilisation; 'walking exercise', consisting of a physiotherapy-supervised, moderate intensity walking program; and 'walking/breathing exercise', consisting of the same moderate intensity walking program, musculoskeletal exercises and respiratory exercises. Primary outcomes; six-minute walking assessment (6MWA) distance, vital capacity and health-related quality of life, were measured pre-operatively, at discharge from hospital and at four weeks following discharge. RESULTS: Walking and walking/breathing exercise groups had significantly higher 6MWA distance (444+/-84 m, 431+/-98 m, respectively) than the standard intervention group (377+/-90 m) at discharge from hospital. There was no significant difference between intervention groups for 6MWA distance at four-week follow-up. There was no significant difference between intervention groups in terms of vital capacity and health-related quality of life. CONCLUSIONS: A physiotherapy-supervised, moderate intensity walking program in the inpatient phase following CABG improves walking capacity at discharge from hospital. The performance of respiratory and musculoskeletal exercises confers no additional benefit to the measured outcomes.

OBJECTIVES: To examine the test-retest reliability and criterion validity of a high-intensity, netball-specific fitness test. DESIGN: Repeated measures, within-subject design. METHODS: Eighteen female netball players competing in an international competition completed a trial of the Net-Test, which consists of 14 timed netball-specific movements. Players also completed a series of netball-relevant criterion fitness tests. Ten players completed an additional Net-Test trial one week later to assess test-retest reliability using intraclass correlation coefficient (ICC), typical error of measurement (TEM), and coefficient of variation (CV). The typical error of estimate expressed as CV and Pearson correlations were calculated between each criterion test and Net-Test performance to assess criterion validity. RESULTS: Five movements during the Net-Test displayed moderate ICC (0.84-0.90) and two movements displayed high ICC (0.91-0.93). Seven movements and heart rate taken during the Net-Test held low CV (<5%) with values ranging from 1.7 to 9.5% across measures. Total time (41.63±2.05s) during the Net-Test possessed low CV and significant (p<0.05) correlations with 10m sprint time (1.98±0.12s; CV=4.4%, r=0.72), 20m sprint time (3.38±0.19s; CV=3.9%, r=0.79), 505 Change-of-Direction time (2.47±0.08s; CV=2.0%, r=0.80); and maximum oxygen uptake (46.59±2.58 mLkg-1min-1; CV=4.5%, r=-0.66). CONCLUSIONS: The Net-Test possesses acceptable reliability for the assessment of netball fitness. Further, the high criterion validity for the Net-Test suggests a range of important netball-specific fitness elements are assessed in combination.

OBJECTIVE: To compare preoperative membranous urethral length (MUL) measurements using magnetic resonance imaging (MRI) with two-dimensional transperineal ultrasound imaging (TPUS) in two supine positions on two separate days in men prior to radical prostatectomy. MATERIALS AND METHODS: MUL was prospectively measured in 18 male volunteers using MRI and on two separate occasions in two different patient positions using TPUS; the patient supine with the knees extended (Supine) and supine with the knees flexed to 70 degrees (Supine KF). Agreement between TPUS and MRI measurements of MUL was assessed using Bland-Altman method comparison techniques and a two-way mixed-effects single measures intraclass correlation (ICC). Test-retest reliability was assessed using a two-way random effects single measures ICC. RESULTS: The mean difference in MUL measurements between MRI and i) TPUS Supine was -0.8 mm (95% limits of agreement (LOA): -3.2, 1.7) and ii) TPUS Supine KF was -0.8mm (95% LOA: -3.5, 1.9). ICC indicated a point estimate of excellent agreement between MRI and TPUS Supine ICC 0.93 (95% CI: 0.76, 0.98) and TPUS Supine KF ICC 0.91 (95%CI 0.79, 0.97). There was excellent agreement between TPUS Supine and TPUS Supine KF (ICC 0.98, 95% CI: 0.96, 0.99) with a mean difference of 0.3mm (95% LOA: -1.2 to 1.3mm). CONCLUSIONS: Preoperative MUL can be reliably measured using TPUS and demonstrates excellent agreement with MRI measurements of MUL. TPUS provides clinicians with an accessible non-invasive alternative to MRI for the measurement of MUL that can be used in outpatient urological settings and for patients where MRI is contraindicated.

CONTEXT: Membranous urethral length (MUL) measured prior to radical prostatectomy (RP) has been identified as a factor that is associated with the recovery of continence following surgery. OBJECTIVE: To undertake a systematic review and meta-analysis of all studies reporting the effect of MUL on the recovery of continence following RP. EVIDENCE ACQUISITION: A comprehensive search of PubMed, EMBASE, and Scopus databases up to September 2015 was performed. Thirteen studies comprising one randomized controlled trial and 12 cohort studies were selected for inclusion. EVIDENCE SYNTHESIS: Four studies (1738 patients) that reported hazard ratio results. Every extra millimeter (mm) of MUL was associated with a faster return to continence (hazard ratio: 1.05; 95% confidence interval [CI]: 1.02-1.08, p<0.001). Eleven studies (6993 patients) reported the OR (OR) for the return to continence at one or more postoperative time points. MUL had a significant positive effect on continence recovery at 3 mo (OR: 1.08, 95% CI: 1.03-1.14, p=0.004), 6 mo (OR: 1.12, 95% CI: 1.09-1.15, p<0.0001). and 12 mo (OR: 1.12, 95% CI: 1.03-1.22, p=0.006) following surgery. After adjusting for repeated measurements over time and studies with overlapping data, all OR data combined indicated that every extra millimeter of MUL was associated with significantly greater odds for return to continence (OR: 1.09, 95% CI: 1.05-1.15, p<0.001). CONCLUSIONS: A greater preoperative MUL is significantly and positively associated with a return to continence in men following RP. Magnetic resonance imaging measurement of MUL is recommended prior to RP. PATIENT SUMMARY: We examined the effect that the length of a section of the urethra (called the membranous urethra) had on the recovery of continence after radical prostatectomy surgery. Our results indicate that measuring the length of the membranous urethra via magnetic resonance imaging before surgery may be useful to predict a longer period of urinary incontinence after surgery, or to explain a delay in achieving continence after surgery.

OBJECTIVES: To quantify physiotherapist-supervised and independent physical activity undertaken from the first to the fifth day after cardiac surgery (POD1 to POD5), and to relate the amount of physical activity undertaken with hospital stay and postoperative physiological functional capacity on POD6. METHODS: Physiotherapist-supervised and independent physical activity were monitored in 83 adult patients undergoing cardiac surgery, using a bi-axial accelerometer and skin sensors that measured, galvanic skin response and body temperature. Patients completed a 6-min walk test (6MWT) on POD6. Step count and physical activity intensity (METs; metbolic equivalents) were the main outcome measures. RESULTS: Males exhibited significantly higher physiotherapist-supervised and independent physical activity step counts and time ≥ 3 METS (p < 0.0001). The 6MWT distance on POD6 was greater in men (mean 393 m, standard deviation (SD) 108 m) than women (mean 300 m, SD 121 m) (p = 0.005). Mean length of stay in hospital was 9 days (SD 3 days) and was negatively correlated with overall physiotherapist-supervised (R = -0.70), independent physical activity step counts (R = -0.62), and combined physiotherapist-supervised (R = -0.65) and independent (R = -0.43) physical activity time ≥ 3 METs. CONCLUSION: Physiotherapist-supervised activity fosters improvements in postoperative physiological functional capacity and reduces length of stay in hospital following cardiac surgery.
