The highly variable rib length provides a challenge for urologists seeking a consistent landmark for Percutaneous Nephrolithotomy (PCNL). We set out to determine whether the twelfth rib is safe to use as a consistent landmark for surgery.Methods: Single centre, cross-sectional retrospective observational study and analysis of CT scans of 100 adults who had imaging between 23rd March and 12th April 2020. The distance from the mid-sagittal line to the twelfth rib tip in the axial plane was measured as was the distance from the twelfth rib tip to the kidney, spleen and liver.Results: Length from the mid-sagittal line to the right twelfth rib tip varied from 46 (percentile 95% CI 40 to 57) to 136mm (percentile 95% CI 133 to 138). On the left, the distances varied from 55 (percentile 95% CI 50 to 64) to 134mm (percentile 95% CI 131 to 135). Twenty-three percent of people had an organ lying between the tip of the twelfth rib and the kidney on the right and 11% on the left.Conclusion: The twelfth rib is highly variable in length. Similar variability was recorded in the distance from the tip to intra-abdominal organs. Due to the frequency of organs lying between the tip of the rib and the kidney it should not be used as a landmark for accessing the kidney without prior knowledge of an individual patient’s anatomy as seen on imaging.Keywords: percutaneous nephrolithotomy, rib, anatomical marker

Peripheral arterial catheters are used for the continuous monitoring of blood pressure and repeated blood sampling in critically ill patients, but can be a source of catheter-related bloodstream infection. A common assumption is that the more frequently an arterial catheter is accessed, the greater the likelihood of contamination and colonisation to occur We sought to determine whether the accessing frequency has an influence on the rate of colonisation in a peripheral arterial catheter A retrospective, unmatched, nested case control study was conducted in our intensive care unit. The intensive care unit charts of 96 arterial catheters from 83 patients were examined to measure the number of times each respective arterial catheter was accessed. Multivariate Cox proportional hazards regression was used to compare the rate of accessing of arterial catheters and account for varying arterial catheter in situ duration. Arterial catheters which had a high access rate of 8.1 or more times/day (five colonised of 32 patients: hazards ratio 1.69, 95% confidence interval 0.52 to 5.49; P = 0.77), or a medium access rate of 6.7 to 8.0 times/day (six colonised of 32 patients: hazards ratio, 1.35, 95% confidence interval, 0.37 to 4.92: P = 0.65) were not significantly more colonised when compared to arterial catheters which had a low access rate of O to 6.6 times/day (six colonised of 32 patients), adjusted for arterial catheter insertion site and place in hospital where the arterial catheter insertion was performed. We were unable to demonstrate that the accessing frequency of an arterial catheter was a major predisposing factor for the likelihood of colonisation. Other mechanisms other than hub colonisation should be investigated further. [ABSTRACT FROM AUTHOR]

Background: Patients on peritoneal and hemodialysis have accelerated atherosclerosis associated with an increase in cardiovascular morbidity and mortality. The atherosclerosis is associated with increased arterial stiffness, endothelial dysfunction and elevated oxidative stress and inflammation. The aims of this study are to investigate the effects of peritoneal and hemodialysis on arterial stiffness, vascular function, myocardial structure and function, oxidative stress and inflammation in incident patients with end stage kidney disease.Methods: This is an observational study. Eighty stage five CKD patients will be enrolled and followed for one-year. Primary outcome measures will be changes in 1) arterial stiffness measured by aortic pulse wave velocity, 2) oxidative stress assessed by plasma F2 isoprostanes and 3) inflammation measured by plasma pentraxin-3. Secondary outcomes will include additional measures of oxidative stress and inflammation, changes in vascular function assessed using the brachial artery reactivity technique, carotid artery intimal medial thickness, augmentation index and trans thoracic echocardiography to assess left ventricular geometry, and systolic and diastolic function. Patients will undergo these measures at baseline (6-8 weeks prior to starting dialysis therapy), then at six and 12 months after starting dialysis.Discussion: The results of this study may guide the choice of dialysis modality in the first year of treatment. It may also lead to a larger study prospectively assessing the effect of dialysis modality on cardiovascular morbidity and mortality.Trial Registration: ACTRN12609000049279. [ABSTRACT FROM AUTHOR]

Background: There is evidence that renal transplant recipients have accelerated atherosclerosis manifest by increased cardiovascular morbidity and mortality. The high incidence of atherosclerosis is, in part, related to increased arterial stiffness, vascular dysfunction, elevated oxidative stress and inflammation associated with immunosuppressive therapy. The dietary supplement astaxanthin has shown promise as an antioxidant and anti-inflammatory therapeutic agent in cardiovascular disease. The aim of this trial is to investigate the effects of astaxanthin supplementation on arterial stiffness, oxidative stress and inflammation in renal transplant patients.Method and Design: This is a randomised, placebo controlled clinical trial. A total of 66 renal transplant recipients will be enrolled and allocated to receive either 12 mg/day of astaxanthin or an identical placebo for one-year. Patients will be stratified into four groups according to the type of immunosuppressant therapy they receive: 1) cyclosporine, 2) sirolimus, 3) tacrolimus or 4) prednisolone+/-azathioprine, mycophenolate mofetil or mycophenolate sodium. Primary outcome measures will be changes in 1) arterial stiffness measured by aortic pulse wave velocity (PWV), 2) oxidative stress assessed by plasma isoprostanes and 3) inflammation by plasma pentraxin 3. Secondary outcomes will include changes in vascular function assessed using the brachial artery reactivity (BAR) technique, carotid artery intimal medial thickness (CIMT), augmentation index (AIx), left ventricular afterload and additional measures of oxidative stress and inflammation. Patients will undergo these measures at baseline, six and 12 months.Discussion: The results of this study will help determine the efficacy of astaxanthin on vascular structure, oxidative stress and inflammation in renal transplant patients. This may lead to a larger intervention trial assessing cardiovascular morbidity and mortality.Trial Registration: ACTRN12608000159358. [ABSTRACT FROM AUTHOR]

Background: There is evidence that dyslipidemia is associated with chronic kidney disease (CKD). Experimental studies have established that lipids are damaging to the kidney and animal intervention studies show statins attenuate this damage. Small clinical trials, meta-analyses, observational studies and post-hoc analyses of cardiovascular intervention studies all support the concept that statins can reduce kidney damage in humans. Based on this background, a double blind randomized placebo controlled trial was designed to assess the effectiveness of atorvastatin 10 mg on slowing the progression of kidney disease in a population of patients with CKD.Method/design: The Lipid lowering and Onset of Renal Disease (LORD) trial is a three-year, single center, multi-site, double blind, randomized, placebo controlled trial. The primary outcome measure is kidney function measured by eGFR calculated by both Modification of Diet in Renal Disease (MDRD) and Cockcroft and Gault equations. Secondary outcome measures include kidney function measured by 24-hour urine creatinine clearance and also 24-hour urinary protein excretion, markers of oxidative stress, inflammation and drug safety and tolerability.Discussion: The results of this study will help determine the effectiveness and safety of atorvastatin and establish its effects on oxidative stress and inflammation in patients with CKD.Trial Registration: ANZCTRN012605000693628.

Management of type 2 diabetes includes medications that can unintentionally increase obesity and insulin resistance. This unblinded, single-centre, randomised controlled trial focused on rural Australian adults with type 2 diabetes (aged 18-75 and body mass index [BMI] >30 kg/m 2 ), measuring the effectiveness of a tailored interdisciplinary obesity care approach compared with usual diabetes care. Led by a nurse practitioner with allied health support (dietitian ± psychologist and physiotherapist), the bariatric treatment involved reducing weight-gaining medications, a 500-calories/day deficit, an unsupervised exercise program emphasising movement/strength and psychotherapy, 3-monthly to 24-months with support phone calls at weeks 2, 4, 8 and 10. Outcomes from the 224 (113 intervention/111 control) participants were differences in biomedical and physical markers within- and between-groups estimated using multivariate mixed-effects linear regression between recruitment and 6-monthly follow-ups. Greater change occurred in intervention compared with control groups at 12 and 24 months in mean: body weight (-5.9 kg [95% confidence interval, CI: -8.53, -3.23] and -9.0 kg [95% CI: -13.2, -4.77]); BMI (-2.03 kg/m 2 [95% CI: -2.92, -1.15] and -3.51 kg/m 2 [95% CI: -4.93, -2.08]); and glycated haemoglobin (-0.26% [95% CI: -0.69%, 0.18%] and -0.63% [95% CI: -1.17%, 0.08%]). The control group showed a significant increase in mean leptin level, resulting in a between-group difference (-27.1 [95% CI: -42.7, -11.5]). Lipids and blood pressure differences were inconclusive, while exploratory analysis showed greater decline in estimated glomerular filtration rate in the control group. The interdisciplinary obesity approach, compared with usual diabetes care, resulted in sustained weight loss and improved diabetes control over 2 years.

Introduction: The burden of defunctioning ileostomy is significant with up to two thirds of patients reporting stoma-related morbidity. While timely reversal is safe and cost-effective, the time to reversal in regional Australian hospitals is not well described in professional publications. We aim to assess the current timeliness of ileostomy closure and identify possible reasons for delaying closure., Methods: A retrospective analysis of loop ileostomies created and reversed in Launceston General Hospital for both rectal cancer surgery and other benign indications was undertaken. Patients with loop ileostomy created between 2010 and 2020 were included. Clinical data of timing of events, complications, readmission and stoma follow-up were recorded; and analysed using multivariate regression analyses to identify clinically relevant risk factors for delayed closure., Results: A total of 123 patients underwent loop-ileostomy formation during the study period, of which 106 patients (86.2%) were reversed. Median time to closure was 8.5 months (IQR 5.2-12.4) for patients with rectal cancers, compared to 5.2 months (IQR 3.6-9.3) for patients who did not have rectal cancer, with a difference of 3.4 months (95% CI 0.9, 5.9; P = 0.008). Adjuvant chemotherapy and unexpected readmission to hospital were associated with delayed reversal (P = 0.0081 and P = 0.0005, respectively)., Conclusion: Stoma reversal is often scheduled 3-6 months after creation. More than two-thirds of patients experienced delays due to changing clinical concerns and non-clinical factors, such as unexpected delays at each stage of surgical planning. Early placement on the waiting list and better-coordinated follow-ups may expedite reversal surgery and reduce associated morbidities., (© 2023 Royal Australasian College of Surgeons.)

Background: Cryptococcus gattii is a globally endemic pathogen causing disease in apparently immune-competent hosts. We describe a 22-year cohort study from Australia's Northern Territory to evaluate trends in epidemiology and management, and outcome predictors., Methods: A retrospective cohort study of all C. gattii infections at the northern Australian referral hospital 1996-2018 was conducted. Cases were defined as confirmed (culture-positive) or probable. Demographic, clinical and outcome data were extracted from medical records., Results: 45 individuals with C. gattii infection were included: 44 Aboriginal Australians; 35 with confirmed infection; none HIV positive out of 38 tested. Multifocal disease (pulmonary and central nervous system) occurred in 20/45 (44%). Nine people (20%) died within 12 months of diagnosis, five attributed directly to C. gattii. Significant residual disability was evident in 4/36 (11%) survivors. Predictors of mortality included: treatment before the year 2002 (4/11 versus 1/34); interruption to induction therapy (2/8 versus 3/37) and end-stage kidney disease (2/5 versus 3/40). Prolonged antifungal therapy was the standard approach in this cohort, with median treatment duration being 425 days (IQR 166-715). Ten individuals had adjunctive lung resection surgery for large pulmonary cryptococcomas (median diameter 6cm [range 2.2-10cm], versus 2.8cm [1.2-9cm] in those managed non-operatively). One died post-operatively, and 7 had thoracic surgical complications, but ultimately 9/10 (90%) treated surgically were cured compared with 10/15 (67%) who did not have lung surgery. Four patients were diagnosed with immune reconstitution inflammatory syndrome which was associated with age <40 years, brain cryptococcomas, high cerebrospinal fluid pressure, and serum cryptococcal antigen titre >1:512., Conclusion: C. gattii infection remains a challenging condition but treatment outcomes have significantly improved over 2 decades, with eradication of infection the norm. Adjunctive surgery for the management of bulky pulmonary C. gattii infection appears to increase the likelihood of durable cure and likely reduces the required duration of antifungal therapy., Competing Interests: I have read the journal’s policy and the authors of this manuscript have the following competing interests:Dr. KH has received advisory board fees and grant support from Gilead Sciences.

Objectives: Postoperative pulmonary complications (PPCs) are a common serious complication following upper abdominal surgery. Postoperatively, physiotherapy-led non-invasive ventilation (NIV) may be a promising method to reduce PPC incidence. The objectives of this pilot trial were to examine preliminary effectiveness, feasibility and safety of additional intermittent physiotherapy-led NIV compared to continuous high-flow nasal cannula oxygen therapy (HFNC) alone., Design: Single-centre, assessor-blinded, parallel-group, pilot randomised control trial., Setting: Primary-referral hospital in Australia., Participants: 130 high-risk patients undergoing upper abdominal surgery., Interventions: Continuous HFNC for 48-hours following surgical extubation, or HFNC plus five 30-minute physiotherapy-led NIV sessions., Outcomes: PPC incidence, trial feasibility and safety., Results: PPC incidence was similar between groups (HFNC alone 12/65 (18%) vs HFNC plus NIV 10/64 (16%) adjusted HR 0.95; 95% CI 0.40-2.29). Delivery of HFNC as per-protocol was achieved in 81% (n = 105) of all participants. Physiotherapy-led NIV initiated within four-hours of surgical extubation was achieved in 81% (n = 52) of intervention group participants, with a mean 4.2 (SD 1.3) total number of NIV sessions delivered in the first two postoperative days. NIV was delivered as per-protocol in 52% of this cohort. Two episodes of severe hypotension during NIV requiring medical intervention were reported., Conclusion: Delivery of continuous HFNC was feasible. Delivery of NIV within four-hours of extubation was achieved and delivered safely with&lt; 1% adverse events. The planned NIV intervention of five sessions within two postoperative days was not feasible. The results of this pilot study have informed the decision not to proceed to a fully powered trial., Clinical Trial Registration: Australian New Zealand Clinical Trials Registry, www.anzctr.org.au ACTRN12617000269336.

Impacts of the COVID-19 pandemic on the mental health of healthcare workers has been established, linking workplace factors with high levels of stress, anxiety, depression, insomnia and burnout. Less established is how COVID-19 affects both work, home and social life of nurses and midwives concurrently. This study describes the prevalence and severity of anxiety, depression, post-traumatic stress disorder (PTSD) and insomnia and examines their associations with stressors within the work, home and social environment, among nurses and midwives. A longitudinal, mixed-methods, online survey explored the psychological health of public sector nurses and midwives during the COVID-19 pandemic first year. Surveys were conducted in April (initial) and June 2020 (3-month), and April 2021 (12-month) and consisted of psychological tests including the Patient Health Questionnaire, General Anxiety Disorder, Insomnia Severity Index, and the Impact of Events Scale-Revised; workplace and lifestyle questions, together with free-text comments. The relative strengths of the associations between predictor and outcome variables were estimated using repeated measures ordered logistic regression, and free text responses were themed. Data show diagnostic levels of anxiety (23%, 18%, 21%) at surveys one, two and three respectively, depression (26%, 23% and 28%), PTSD (16%, 12% and 10%) and insomnia (19%, 19% and 21%). The strongest predictors of psychological distress were current home and family stress and poor clinical team support. Factors which will help preserve the mental health of nurses and midwives include strong workplace culture, reducing occupational risk, clear communication processes, and supporting stable and functional relationships at home. The COVID-19 pandemic has increased the visibility of mental distress on nurses and midwives and established they are pivotal to healthcare. The health service has a duty-of-care for the welfare of nurses and midwives who have entered this psychologically taxing profession to future proof service delivery and safeguard its service-response capacity., Competing Interests: The authors have declared that no competing interests exist.

Maternal obesity in pregnancy, a growing health problem in Australia, adversely affects both mothers and their offspring. Gestational diabetes mellitus (GDM) is similarly associated with adverse pregnancy and neonatal complications. A low-risk digital medical record audit of antenatal and postnatal data of 2132 pregnant mothers who gave birth between 2016-2018 residing in rural-regional Tasmania was undertaken. An expert advisory group guided the research and informed data collection. Fifty five percent of pregnant mothers were overweight or obese, 43.6% gained above the recommended standards for gestational weight gain and 35.8% did not have an oral glucose tolerance test. The audit identified a high prevalence of obesity among pregnant women and low screening rates for gestational diabetes mellitus associated with adverse maternal and neonatal pregnancy outcomes. We conclude that there is a high prevalence of overweight and obesity among pregnant women in rural regional Tasmania. Further GDM screening rates are low, which require addressing.

Background: Preoperative education and breathing exercise training by a physiotherapist minimises pulmonary complications after abdominal surgery. Effects on specific clinical outcomes such as antibiotic prescriptions, chest imaging, sputum cultures, oxygen requirements, and diagnostic coding are unknown., Methods: This post hoc analysis of prospectively collected data within a double-blinded, multicentre, randomised controlled trial involving 432 participants having major abdominal surgery explored effects of preoperative education and breathing exercise training with a physiotherapist on postoperative antibiotic prescriptions, hypoxemia, sputum cultures, chest imaging, auscultation, leukocytosis, pyrexia, oxygen therapy, and diagnostic coding, compared to a control group who received a booklet alone. All participants received standardised postoperative early ambulation. Outcomes were assessed daily for 14 postoperative days. Analyses were intention-to-treat using adjusted generalised multivariate linear regression., Results: Preoperative physiotherapy was associated with fewer antibiotic prescriptions specific for a respiratory infection (RR 0.52; 95% CI 0.31 to 0.85, p = 0.01), less purulent sputum on the third and fourth postoperative days (RR 0.50; 95% CI 0.34 to 0.73, p = 0.01), fewer positive sputum cultures from the third to fifth postoperative day (RR 0.17; 95% CI 0.04 to 0.77, p = 0.01), and less oxygen therapy requirements (RR 0.49; 95% CI 0.31 to 0.78, p = 0.002). Treatment effects were specific to respiratory clinical coding domains., Conclusions: Preoperative physiotherapy prevents postoperative pulmonary complications and is associated with the minimisation of signs and symptoms of pulmonary collapse/consolidation and airway infection and specifically results in reduced oxygen therapy requirements and antibiotic prescriptions., Trial Registration: ANZCTR 12613000664741 ; 19/06/2013., (© 2021.

Question: Is preoperative physiotherapy cost-effective in reducing postoperative pulmonary complications (PPC) and improving quality-adjusted life years (QALYs) after major abdominal surgery?, Design: Cost-effectiveness analysis from the hospitals' perspective within a multicentre randomised controlled trial with concealed allocation, blinded assessors and intention-to-treat analysis., Participants: Four hundred and forty-one adults awaiting elective upper abdominal surgery attending pre-anaesthetic clinics at three public hospitals in Australia and New Zealand., Interventions: The experimental group received an information booklet and a 30-minute face-to-face session, involving respiratory education and breathing exercise training, with a physiotherapist. The control group received the information booklet only., Outcome Measures: The probability of cost-effectiveness and incremental net benefits was estimated using bootstrapped incremental PPC and QALY cost-effectiveness ratios plotted on cost-effectiveness planes and associated probability curves through a range of willingness-to-pay amounts. Cost-effectiveness modelling utilised 21-day postoperative hospital cost audit data and QALYs estimated from Short Form-Six Domain health utilities and mortality to 12 months., Results: Preoperative physiotherapy had 95% probability of being cost-effective with an incremental net benefit to participating hospitals of A$4,958 (95% CI 10 to 9,197) for each PPC prevented, given that the hospitals were willing to pay $45,000 to provide the service. Cost-utility for QALY gains was less certain. Sensitivity analyses strengthened cost-effectiveness findings. Improved cost-effectiveness and QALY gains were detected when experienced physiotherapists delivered the intervention., Conclusions: Preoperative physiotherapy aimed at preventing PPCs was highly likely to be cost-effective from the hospitals' perspective. For each PPC prevented, preoperative physiotherapy is likely to cost the hospitals less than the costs estimated to treat a PPC after surgery. Potential QALY gains require confirmation., Trial Registration: ACTRN12613000664741., (Copyright © 2020 Australian Physiotherapy Association. Published by Elsevier B.V. All rights reserved.)

Objectives: To (1) determine whether short, 30-minute sessions of non-invasive ventilation (NIV) is associated with fewer postoperative pulmonary complications (PPC) following elective high-risk upper abdominal surgery and (2) measure feasibility and safety of this intervention when delivered by physiotherapists., Design: Prospective, pre post cohort, observational, single-centre study., Setting: Primary referral hospital in Australia., Participants: A total of 182 consecutive high-risk elective upper abdominal surgery patients consisting of 101 pre cohort participants compared to 81 post cohort participants., Interventions: Both groups received standardised preoperative physiotherapy and early postoperative mobilisation. The post cohort group received five additional 30-minute NIV sessions in the first two postoperative days., Main Outcome Measure: Primary outcome measure was PPC incidence within the first seven postoperative days. Secondary outcomes included feasibility and safety of physiotherapy-led NIV., Results: Incidence of PPC (7% vs 18%, adjusted relative risk 0.24; 95% CI 0.10 to 0.59, p=0.002) was less in the NIV group compared to those who received no NIV. Mean time to first NIV session was 18.6 (SD 11.0) hours with 74% of participants receiving NIV within 24-hours of surgery. There were no major adverse events., Conclusion: These findings suggest PPC reduction may be possible with postoperative NIV following high-risk elective upper abdominal surgery. Results should be seen as hypothesis-generating associations only considering the significant limitations to this study. Physiotherapy-led NIV was delivered safely to ICU and ward patients. However, the planned protocol was not feasible and appropriate physiotherapy staffing and/or a multidisciplinary approach may be required to provide this service successfully., Trial Registration: LIPPSMAck POP (Lung Infection Prevention Post Surgery - Major Abdominal - with Pre Operative Physiotherapy) ANZCTR-12613000664741 (for pre cohort group only)., (Copyright © 2018 Chartered Society of Physiotherapy.

Introduction: Postoperative pulmonary complications (PPCs) are a common serious complication following upper abdominal surgery leading to significant consequences including increased mortality, hospital costs and prolonged hospitalisation. The primary objective of this study is to detect whether there is a possible signal towards PPC reduction with the use of additional intermittent non-invasive ventilation (NIV) compared with continuous high-flow nasal oxygen therapy alone following high-risk elective upper abdominal surgery. Secondary objectives are to measure feasibility of: (1) trial conduct and design and (2) physiotherapy-led NIV and a high-flow nasal oxygen therapy protocol, safety of NIV and to provide preliminary costs of care information of NIV and high-flow nasal oxygen therapy., Methods and Analysis: This is a single-centre, parallel group, assessor blinded, pilot, randomised trial, with 130 high-risk upper abdominal surgery patients randomly assigned via concealed allocation to either (1) usual care of continuous high-flow nasal oxygen therapy for 48 hours following extubation or (2) usual care plus five additional 30 min physiotherapy-led NIV sessions within the first two postoperative days. Both groups receive standardised preoperative physiotherapy and postoperative early ambulation. No additional respiratory physiotherapy is provided to either group. Outcome measures will assess incidence of PPC within the first 14 postoperative days, recruitment ability, physiotherapy-led NIV and high-flow nasal oxygen therapy protocol adherence, adverse events relating to NIV delivery and costs of providing a physiotherapy-led NIV and a high-flow nasal oxygen therapy service following upper abdominal surgery., Ethics and Dissemination: Ethics approval has been obtained from the relevant institution and results will be published to inform future multicentre trials., Trial Registration Number: ACTRN12617000269336; Pre-results., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Background: Reduction in postoperative pain, nausea, and vomiting in patients undergoing total joint arthroplasty may facilitate earlier discharge from hospital and reduce healthcare costs. This study was performed to primarily assess whether perioperative dexamethasone reduced hospital length of stay and to assess the effect on pain, nausea and vomiting, and patient satisfaction., Methods: One hundred sixty-four patients undergoing total hip arthroplasty or total knee arthroplasty were randomized to receive either 8 mg intravenous dexamethasone (n = 86) or placebo (n = 78) at induction and at 24 hours postsurgery. The primary outcome was length of stay and secondary outcomes were pain and nausea visual analog scale scores, analgesic and antiemetic usage, blood glucose level, and patient satisfaction., Results: Participants in the study group achieved earlier readiness for discharge. There was a 20% reduction in pain scores and morphine usage was 27% lower in the study group. Nausea scores were similar in the 2 groups but there was lower antiemetic usage in the study group. Satisfaction scores at 6 weeks postsurgery in the dexamethasone group were significantly higher than the placebo group. There was no difference in complication rates between the 2 groups., Conclusion: The administration of intravenous dexamethasone could lead to earlier readiness for discharge especially in patients undergoing elective total hip arthroplasty, primarily by a reduction in postoperative pain scores and/or morphine requirements., (Copyright © 2018 Elsevier Inc.

Objectives: To (1) assess memorability and treatment fidelity of pre-operative physiotherapy education prior to elective upper abdominal surgery and, (2) to explore patient opinions on pre-operative education., Design: Mixed-methods analysis of a convenience sample within a larger parallel-group, double-blinded, randomised controlled trial with concealed allocation and intention-to-treat analysis., Setting: Tertiary Australian hospital., Participants: Twenty-nine patients having upper abdominal surgery attending pre-admission clinic within six-weeks of surgery., Intervention: The control group received an information booklet about preventing pulmonary complications with early ambulation and breathing exercises. The experimental group received an additional face-to-face 30-minute physiotherapy education and training session on pulmonary complications, early ambulation, and breathing exercises., Outcome Measures: Primary outcome was proportion of participants who remembered the taught breathing exercises following surgery. Secondary outcomes were recall of information sub-items and attainment of early ambulation goals. These were measured using standardised scoring of a semi-scripted digitally-recorded interview on the 5th postoperative day, and the attainment of early ambulation goals over the first two postoperative days., Results: Experimental group participants were six-times more likely to remember the breathing exercises (95%CI 1.7 to 22) and 11-times more likely (95%CI 1.6 to 70) to report physiotherapy as the most memorable part of pre-admission clinic. Participants reported physiotherapy education content to be detailed, interesting, and of high value. Some participants reported not reading the booklet and professed a preference for face-to-face information delivery., Conclusion: Face-to-face pre-operative physiotherapy education and training prior to upper abdominal surgery is memorable and has high treatment fidelity., Trial Registration: ACTRN-12613000664741., (Copyright © 2017 Chartered Society of Physiotherapy.

Background: Gestational diabetes mellitus (GDM) is associated with life-long increased risk of type 2 diabetes: affected women are advised to undergo oral glucose tolerance testing (OGTT) at 6-12 weeks postpartum, then glucose screening every 1-3 years., Aims: We investigated whether in women with GDM, antenatal clinical factors predicted postpartum abnormal glucose tolerance and compliance with screening., Materials and Methods: In women with GDM delivering 2007 to mid-2009 in a single hospital, antenatal/obstetric data and glucose tests at 6-12 weeks postpartum and during 5.5 years post-pregnancy were retrospectively collected. Predictors of return for testing and abnormal glucose tolerance were identified using multivariate analysis., Results: Of 165 women, 117 (70.9%) returned for 6-12 week postpartum OGTT: 23 (19.6%) were abnormal. Smoking and parity, independent of socioeconomic status, were associated with non-return for testing. Fasting glucose ≥5.4 mmol/L on pregnancy OGTT predicted both non-return for testing and abnormal OGTT. During 5.5 years post-pregnancy, 148 (89.7%) women accessed glucose screening: nine (6.1%) developed diabetes, 33 (22.3%) had impaired fasting glucose / impaired glucose tolerance. Predictors of abnormal glucose tolerance were fasting glucose ≥5.4 mmol/L and 2-h glucose ≥9.3 mmol/L on pregnancy OGTT (~2.5-fold increased risk), and polycystic ovary syndrome (~3.4 fold increased risk). Risk score calculation, based on combined antenatal factors, did not improve predictions., Conclusions: Antenatal clinical factors were modestly predictive of return for testing and abnormal glucose tolerance post-pregnancy in women with GDM. Risk score calculations were ineffective in predicting outcomes: risk scores developed in other populations require validation. Ongoing glucose screening is indicated for all women with GDM., (© 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)
