RESUMO

BACKGROUND: Most adolescent girls fail to meet current physical activity guidelines. Physical activity behaviours track from childhood into adulthood and providing adolescent girls with opportunities to be physically active may have health benefits beyond childhood. The effects of walking interventions on adult cardiometabolic health are known, however less is understood about the potential of walking to promote physical activity in adolescents. Following the Walking In ScHools (WISH) feasibility study, this definitive trial aimed to evaluate the effectiveness of a novel, low-cost, school-based walking intervention at increasing physical activity levels of adolescent girls (aged 12-14 years). METHODS: Female pupils were recruited from eighteen schools across the border region of Ireland and in Northern Ireland. In intervention schools (n = 9), girls aged 15-18 years, were trained as walk leaders, and led the younger pupils in 10-15 min walks before school, at break and lunch recess. All walks took place in school grounds and pupils were encouraged to participate in as many walks as possible each week. The primary outcome measure was accelerometer determined total physical activity (counts per minutes, cpm). RESULTS: In total, 589 pupils were recruited to the study. At baseline, pupils engaged in a median (interquartile range (IQR)) 35.7 (21.2) mins moderate-vigorous physical activity (MVPA) per day and only 12% (n = 66) of participants met physical activity guidelines (60 min MVPA per day). The intervention was delivered for a mean (standard deviation (SD)) 19.9 ± 0.97 weeks. The mean post-intervention total physical activity for the intervention group was 676 cpm and 710 cpm in the control group. Post-intervention total physical activity did not statistically differ between groups when adjusted for age, body mass index z-scores and baseline physical activity (mean difference, -33.5, 95% CI = -21.2 to 88.1; p = 0.213). CONCLUSIONS: 'Scaling-up' physical activity interventions is challenging and despite a promising feasibility study, the results of this fully powered trial suggest that in this context, the WISH intervention did not increase device measured physical activity. Since the COVID-19 pandemic, school environments have changed and although pupils enjoyed the programme, attendance at walks was low, indicating that there is a need to better understand how to implement interventions within schools.

RESUMO

BACKGROUND: Adolescent girls in the UK and Ireland fail to meet physical activity (PA) guidelines. PA behaviours track from childhood into adulthood. The effects of walking interventions on adult health are known; however, the potential of walking to promote PA in adolescents is less known. This study evaluated the effectiveness of a novel, school-based walking intervention aimed at increasing PA levels of adolescent girls. METHODS: In this cluster-randomised controlled trial, female pupils aged 12-14 years were recruited from 18 (mixed or single-sex) schools across the border region of Ireland and Northern Ireland. Schools were randomly assigned to either the control group (usual physical activity; n=9) or the intervention group (n=9) by independent faculty staff using an online randomisation tool (randomization.com). In intervention schools, female pupils aged 15-18 years were trained as walk leaders and led the younger pupils in 10-15 min walks before school, at break, and at lunchtime. Walks were in school grounds and pupils were encouraged to join as many walks as possible. The intervention was delivered for a full school year excluding holidays (for a total of 18-21 weeks). Accelerometers measured PA, and the primary outcome was total PA (counts per minute [cpm]). Ethics approval was granted by Ulster University Research Ethics Committee and written informed consent (parent or guardian) and assent (pupils) was obtained. This study is registered with the ISRCTN Registry, 12847782. FINDINGS: The study took place from Sept 1, 2021, to May 31, 2023. In total, 589 pupils were recruited (n=286 in intervention group; n=303 in control group). Median moderate-vigorous PA (MVPA) at baseline was 36·1 min/day (IQR 23·0) for the intervention group and 35·3 min/day (19·8) for the control group. Only 37 (15%) girls in the intervention group and 29 (10%) girls in the control group met PA guidelines (60 min/day of MVPA). The mean total PA after intervention was 676 cpm (SD 18·7) for the intervention group and 710 cpm (SD 17·7) for the control group. Post-intervention total PA did not differ between groups when adjusted for age, body-mass index, z-scores, and baseline PA (mean difference -33·5, 95% CI -21·2 to 88·1; p=0·213). INTERPRETATION: Scaling up PA interventions is challenging. Despite a promising feasibility study, the results of this fully powered trial indicate that in this context, the walking programme did not increase PA. Since the COVID-19 pandemic, school environments have changed, and although pupils enjoyed the programme, attendance at walks was low. There is a need to better understand the implementation of interventions such as this within schools. FUNDING: Cross-border Healthcare Intervention Trials in Ireland Network (CHITIN).

RESUMO

BACKGROUND: Young people have the right to be informed and consulted about decisions affecting their lives. Patient and public involvement (PPI) ensures that research is carried out 'with' or 'by' young people rather than 'to', 'about' or 'for' them. The aim of this paper is to outline how youth PPI can be embedded within a physical activity intervention, reflect on the impact of PPI and provide recommendations for future PPI in a similar context. METHODS: A Youth Advisory Group (YAG) was set up within the Walking In ScHools (WISH) Study to involve adolescent girls in the delivery, implementation and dissemination of a physical activity intervention targeted at adolescents. Schools invited pupils aged 12-14 years and 15-18 years to YAG meetings (n3, from 2019 to 2023). Participative methods were used to inform recruitment strategies and data collection methods for the WISH Study. RESULTS: Across the three YAG meetings, n51 pupils from n8 schools were involved. Pupils enjoyed the YAG meetings, felt that their feedback was valued and considered the meetings a good way to get young people involved in research. The YAG advised on specific issues and although measuring impact was not the primary aim of the YAG meetings, over the course of the study there were many examples of the impact of PPI. Recruitment targets for the WISH Study were exceeded, the attrition rate was low and pupils were engaged in data collection. CONCLUSION: Youth PPI is a developing field and there are few physical activity studies that report the PPI work undertaken. Within the WISH Study, three YAG meetings were held successfully, and the views of adolescent girls were central to the development of the study. Considering the specific issues that the YAG advised on (study recruitment, attrition and data collection), there was evidence of a positive impact of PPI. PATIENT OR PUBLIC CONTRIBUTION: Pupils from post-primary schools interested/participating in the WISH Study were invited to attend YAG meetings. YAG meetings were set up to consult adolescent girls on the delivery, implementation and dissemination of the WISH intervention.

RESUMO

Introduction: Focussed professionalism training improves surgical trainees' communication, information gathering, and counselling skills. This study reviews the impact of a professionalism workshop for surgical trainees within a large trust in the United Kingdom developed during the pandemic to support the trainees and help them develop resilience and appropriate behaviours during the time of increased pressure. Methods: A workshop involving case-based discussions and reflections on professionalism was developed from the themes and methods of training noted to be effective on a literature search of Medline, EMBASE, and PsycINFO databases carried out in May 2020. The impact of Covid on surgical trainees and educator's professionalism training and the techniques of training preferred by trainees was evaluated by a survey of trainees and trainers after the intervention to evolve future training initiatives. During the workshop, a behavioural marker checklist was used to improve feedback on the observed behaviours. Results: 83 trainers and trainees were surveyed following a professional behaviour workshop training 63 surgeons at various stages of training. Surgical list availability had reduced by at least 5-10 a month for all the trainees within the trust during the pandemic. Most trainees surveyed (49 (60%)) felt that this had reduced the opportunities to train technical skills and develop professional non-technical skills like teamwork and communication skills, adversely impacting the trainee's clinical performance. The increased support offered by the workshop helped 50 trainees (80%) to improve non-technical skill performance objectively by referencing to behavioural markers and this was felt to have become embedded in practice when surveyed 4 weeks later in 38 trainees (60%). The majority of those surveyed (47 (75%)) felt trainers and trainees had acted professionally during the pandemic and subsequently. The workshop discussions also helped (56 (67%)) trainers and trainees to consider how best to engage professionally with new ways of working as work, and training switched to virtual or telemedicine platforms during the pandemic. Conclusions: Professionalism-based education facilitates surgical trainee development, making them stronger team members and helping to restore team working skills and embrace new working practices.

RESUMO

Background: This review aims to compare the outcomes for day case shoulder replacement with in-patient shoulder replacement surgery in a district general hospital. Methods: Seventy-three patients had 82 shoulder arthroplasty procedures. Forty-six procedures were undertaken in a dedicated stand-alone day-case unit and 36 were undertaken as in-patient cases. Patient were followed up at 6 weeks, 6 months and annually. Results: There was no significant difference between the outcomes of shoulder arthroplasty procedures performed in the day case or in-patient settings making this a safe option for surgical care in a unit with an appropriate care pathway. Six complications in total were observed, three in each group. Operation time was statistically shorter for day cases by 25.1 min (95% CI - 36.5 to -13.7; d = -0.95, 95% CI -1.42 to 0.48). Estimated marginal means (EMM) revealed lower post-surgery oxford pain scores in day cases (EMM = 3.25, 95% CI 2.35, 4.16) compared with inpatients (EMM = 4.65, 95% CI 3.64 to 5.67). Constant shoulder scores were higher in day cases versus inpatients. Conclusion: Day case shoulder replacement is safe with comparable outcomes to routine inpatient care for patients up to ASA 3 classification with high satisfaction and excellent functional outcomes.

RESUMO

Background: Exercise is recommended for people with cancer. The aim of this study was to evaluate the harms of exercise in patients with cancer undergoing systemic treatment. Methods: This systematic review and meta-analysis included published and unpublished controlled trials comparing exercise interventions versus controls in adults with cancer scheduled to undergo systemic treatment. The primary outcomes were adverse events, health-care utilization, and treatment tolerability and response. Eleven electronic databases and trial registries were systematically searched with no date or language restrictions. The latest searches were performed on April 26, 2022. The risk of bias was judged using RoB2 and ROBINS-I, and the certainty of evidence for primary outcomes was assessed using GRADE. Data were statistically synthesised using pre-specified random-effect meta-analyses. The protocol for this study was registered in the PROESPERO database (ID: CRD42021266882). Findings: 129 controlled trials including 12,044 participants were eligible. Primary meta-analyses revealed evidence of a higher risk of some harms, including serious adverse events (risk ratio [95% CI]: 1.87 [1.47-2.39], I2 = 0%, n = 1722, k = 10), thromboses (risk ratio [95% CI]: 1.67 [1.11-2.51], I2 = 0%, n = 934, k = 6), and fractures (risk ratio [95% CI]: 3.07 [3.03-3.11], I2 = 0%, n = 203, k = 2) in intervention versus control. In contrast, we found evidence of a lower risk of fever (risk ratio [95% CI]: 0.69 [0.55-0.87], I2 = 0% n = 1109, k = 7) and a higher relative dose intensity of systemic treatment (difference in means [95% CI]: 1.50% [0.14-2.85], I2 = 0% n = 1110, k = 13) in intervention versus control. For all outcomes, we downgraded the certainty of evidence due to imprecision, risk of bias, and indirectness, resulting in very low certainty of evidence. Interpretation: The harms of exercise in patients with cancer undergoing systemic treatment are uncertain, and there is currently insufficient data on harms to make evidence-based risk-benefits assessments of the application of structured exercise in this population. Funding: There was no funding for this study.

RESUMO

BACKGROUND: Primary hyperparathyroidism (PHPT), a disorder in which the parathyroid glands produce excessive amounts of parathyroid hormone, is most common in older adults and postmenopausal women. While most people with PHPT are asymptomatic at diagnosis, symptomatic disease can lead to hypercalcaemia, osteoporosis, renal stones, cardiovascular abnormalities and reduced quality of life. Surgical removal of abnormal parathyroid tissue (parathyroidectomy) is the only established treatment for adults with symptomatic PHPT to prevent exacerbation of symptoms and to be cured of PHPT. However, the benefits and risks of parathyroidectomy compared to simple observation or medical therapy for asymptomatic and mild PHPT are not well established. OBJECTIVES: To evaluate the benefits and harms of parathyroidectomy in adults with PHPT compared to simple observation or medical therapy. SEARCH METHODS: We searched CENTRAL, MEDLINE, LILACS, ClinicalTrials.gov and WHO ICTRP from their date of inception until 26 November 2021. We applied no language restrictions. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing parathyroidectomy with simple observation or medical therapy for the treatment of adults with PHPT. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were 1. cure of PHPT, 2. morbidity related to PHPT and 3. serious adverse events. Our secondary outcomes were 1. all-cause mortality, 2. health-related quality of life and 3. hospitalisation for hypercalcaemia, acute renal impairment or pancreatitis. We used GRADE to assess the certainty of the evidence for each outcome. MAIN RESULTS: We identified eight eligible RCTs that included 447 adults with (mostly asymptomatic) PHPT; 223 participants were randomised to parathyroidectomy. Follow-up duration varied from six months to 24 months. Of the 223 participants (37 men) randomised to surgery, 164 were included in the analyses, of whom 163 were cured at six to 24 months (overall cure rate 99%). Parathyroidectomy compared to observation probably results in a large increase in cure rate at six to 24 months follow-up: 163/164 participants (99.4%) in the parathyroidectomy group and 0/169 participants in the observation or medical therapy group were cured of their PHPT (8 studies, 333 participants; moderate certainty).  No studies explicitly reported intervention effects on morbidities related to PHPT, such as osteoporosis, osteopenia, kidney dysfunction, urolithiasis, cognitive dysfunction or cardiovascular disease, although some studies reported surrogate outcomes for osteoporosis and cardiovascular disease. A post-hoc analysis revealed that parathyroidectomy, compared to observation or medical therapy, may have little or no effect after one to two years on bone mineral density (BMD) at the lumbar spine (mean difference (MD) 0.03 g/cm2,95% CI -0.05 to 0.12; 5 studies, 287 participants; very low certainty). Similarly, compared to observation, parathyroidectomy may have little or no effect on femoral neck BMD after one to two years (MD -0.01 g/cm2, 95% CI -0.13 to 0.11; 3 studies, 216 participants; very low certainty). However, the evidence is very uncertain for both BMD outcomes. Furthermore, the evidence is very uncertain about the effect of parathyroidectomy on improving left ventricular ejection fraction (MD -2.38%, 95% CI -4.77 to 0.01; 3 studies, 121 participants; very low certainty). Four studies reported serious adverse events. Three of these reported zero events in both the intervention and control groups; consequently, we were unable to include data from these three studies in the pooled analysis. The evidence suggests that parathyroidectomy compared to observation may have little or no effect on serious adverse events (RR 3.35, 95% CI 0.14 to 78.60; 4 studies, 168 participants; low certainty).  Only two studies reported all-cause mortality. One study could not be included in the pooled analysis as zero events were observed in both the intervention and control groups. Parathyroidectomy compared to observation may have little or no effect on all-cause mortality, but the evidence is very uncertain (RR 2.11, 95% CI 0.20 to 22.60; 2 studies, 133 participants; very low certainty). Three studies measured health-related quality of life using the 36-Item Short Form Health Survey (SF-36) and reported inconsistent differences in scores for different domains of the questionnaire between parathyroidectomy and observation. Six studies reported hospitalisations for the correction of hypercalcaemia. Two studies reported zero events in both the intervention and control groups and could not be included in the pooled analysis. Parathyroidectomy, compared to observation, may have little or no effect on hospitalisation for hypercalcaemia (RR 0.91, 95% CI 0.20 to 4.25; 6 studies, 287 participants; low certainty). There were no reported hospitalisations for renal impairment or pancreatitis. AUTHORS' CONCLUSIONS: In accordance with the literature, our review findings suggest that parathyroidectomy, compared to simple observation or medical (etidronate) therapy, probably results in a large increase in cure rates of PHPT (with normalisation of serum calcium and parathyroid hormone levels to laboratory reference values). Parathyroidectomy, compared with observation, may have little or no effect on serious adverse events or hospitalisation for hypercalcaemia, and the evidence is very uncertain about the effect of parathyroidectomy on other short-term outcomes, such as BMD, all-cause mortality and quality of life. The high uncertainty of evidence limits the applicability of our findings to clinical practice; indeed, this systematic review provides no new insights with regard to treatment decisions for people with (asymptomatic) PHPT. In addition, the methodological limitations of the included studies, and the characteristics of the study populations (mainly comprising white women with asymptomatic PHPT), warrant caution when extrapolating the results to other populations with PHPT. Large-scale multi-national, multi-ethnic and long-term RCTs are needed to explore the potential short- and long-term benefits of parathyroidectomy compared to non-surgical treatment options with regard to osteoporosis or osteopenia, urolithiasis, hospitalisation for acute kidney injury, cardiovascular disease and quality of life.

RESUMO

Objective: To examine the accuracy of urine c-peptide creatinine ratio (UCPCR) for identifying the type of diabetes in appropriate clinical settings. Design: Systematic review of test accuracy studies on patients with different forms of diabetes. Data sources: Medline, Embase and Cochrane library databases from 1 January 2000 to 15 November 2020. Eligibility criteria: Studies reporting the use of UCPCR for diagnosing patients with type 1 diabetes mellitus (T1DM), type 2 diabetes mellitus (T2DM) and monogenic forms of diabetes (categorized as maturity-onset diabetes of the young [MODY]). Study selection and data synthesis: Two reviewers independently assessed articles for inclusion and assessed the methodological quality of the studies using the Quality Assessment of Diagnostic Accuracy Studies-2 tool, with input from a third reviewer to reach consensus when there was a dispute. Meta-analysis was performed with the studies reporting complete data to derive the pooled sensitivity, specificity and diagnostic odds ratio (DOR), and narrative synthesis only for those with incomplete data. Results: Nine studies with 4,488 patients were included in the qualitative synthesis, while only four of these (915 patients) had complete data and were included in the quantitative synthesis. All the studies had moderate risk of bias and applicability concerns. Meta-analysis of three studies (n=130) revealed sensitivity, specificity and DOR of 84.4% (95% confidence interval [CI] 68.1-93.2%), 91.6% (82.8-96.1%) and 59.9 (32.8-106.0), respectively, for diagnosing T1DM using a UCPCR cut-off of <0.2 nmol/mmol. For participants with T2DM (three studies; n=739), UCPCR >0.2 nmol/mmol was associated with sensitivity, specificity and DOR of 92.8% (84.2-96.9%), 81.6% (61.3-92.5%) and 56.9 (31.3-103.5), respectively. For patients with MODY in the appropriate clinical setting, a UCPCR cut-off of >0.2 nmol/mmol showed sensitivity, specificity and DOR of 85.2% (73.1-92.4%), 98.0% (92.4-99.5%) and 281.8 (57.5-1,379.7), respectively. Conclusions: Based on studies with moderate risk of bias and applicability concerns, UCPCR confers moderate to high sensitivity, specificity, and DOR for correctly identifying T1DM, T2DM and monogenic diabetes in appropriate clinical settings. Large multinational studies with multi-ethnic participation among different age groups are necessary before this test can be routinely used in clinical practice. Study registration: Protocol was registered as PROSPERO CRD42017060633.

RESUMO

Exercise training is emerging as a supportive treatment strategy in surgical oncology, but its effects remain uncertain in patients with gastrointestinal cancer. The primary objective of this systematic review and meta-analysis was to evaluate the effects of perioperative exercise training on gastrointestinal cancer-specific mortality, recurrence, and surgical outcomes (postoperative complications, hospitalization, surgical stress) in patients with gastrointestinal cancer. Randomized or quasi-randomized controlled trials evaluating the effects of perioperative exercise training versus control in patients with GI cancer were eligible. MEDLINE, EMBASE, CENTRAL, CINAHL, PEDro, and SPORTDiscus were systematically searched on June 20, 2020. Data were synthesized using random-effects meta-analyses. Risk of bias was assessed using the Cochrane risk of bias tool 2, and the certainty of evidence was assessed using GRADE. Study selection, data extraction, risk of bias, and GRADE assessments were performed independently by two authors. Ten randomized controlled trials comprising 448 participants with gastrointestinal cancer were eligible. Meta-analyses indicated no statistical effects of exercise on postoperative complications (risk ratio: 1.11, 95% CI: 0.84; 1.47), readmissions (risk ratio: 2.76; 95% CI: 0.00, 9394.76), or postoperative length of stay (difference in means: -0.47, 95% CI: -17.2; 16.2 days). None of the eligible studies assessed gastrointestinal cancer-specific mortality or recurrence. Overall risk of bias was high or of some concerns in all studies, and the certainty of evidence was very low. The effects of perioperative exercise on cancer-specific and surgical outcomes are unknown in patients with gastrointestinal cancer due to lack of studies and very low certainty of evidence.

RESUMO

BACKGROUND: To suppress the transmission of coronavirus, many governments, including that of the island of Ireland, implemented a societal lockdown, which included school closures, limits on social gatherings, and time outdoors. This study aimed to evaluate changes in physical activity (PA), mental health, sleep, and social media use among adolescent girls during lockdown. METHODS: 281 female pupils (12-14 y) taking part in the ongoing Walking In Schools study on the island of Ireland self-reported PA, mental health, sleep, and social media use before (September-October 2019) and during lockdown (May-June 2020), via questionnaires. These were supplemented with open-ended structured interviews conducted with 16 girls during lockdown. RESULTS: During the period of lockdown and school closures, pupils tried new forms of PA and undertook PA with family, but there was no significant change in self-reported PA. There was a decline in health-related quality of life and motivation for exercise; however, self-efficacy for walking and happiness with appearance increased. There was no change in sleep quality or social media usage. CONCLUSIONS: Despite the many challenges that schools face as they reopen, there is a need to continue to prioritize PA and motivation for exercise to support health and well-being in adolescent girls.

RESUMO

BACKGROUND: Non-functioning pituitary macroadenomas (NFPAs) with visual field defects are ideally managed by transsphenoidal tumour resection to improve vision, and long-term postsurgical follow up is necessary to monitor for tumour recurrence. Regular updates from global data are necessary for developing optimal management strategies of these tumours. METHODS: Pre- and postoperative visual and endocrine profile, imaging characteristics and details of surgical interventions among patients with NFPAs managed between 2008 and 2019 in a UK regional centre were assessed. The radiological and surgical outcomes including postoperative complications, recurrence risk and the factors influencing outcomes also were assessed. RESULTS: 105 cases with mean (SD) age 60.1 (14.3) years and follow-up duration 60 (37) months were studied. 67 (64%) patients were male. Five-year recurrence-free survival rate was 71.5% (95% confidence interval [CI] 62.7% to 81.6%) with 33 (31%) tumour recurrences of whom 20 (60%) received radiotherapy and 9 (27%) underwent further surgery. Younger age, tumour volume, and bilateral cavernous sinus extension were the predictors of recurrence on univariate analysis, while younger age was the only factor on multivariate analysis (Hazard ratio 0.95; 95% CI: 0.92, 0.97). 72/78 patients (92%) with preoperative visual field defects improved after surgery, of whom 27 (35%) had full recovery. 20 (24%) patients had recovery of an abnormal hormone axis. 15 patients (16%) developed perioperative complications such as cerebrospinal fluid leak (12 cases), meningitis (2 cases), and bleeding (2 cases). CONCLUSIONS: Five-year recurrence-free survival after transsphenoidal resection for NFPAs was 71.5% with older age at surgery conferring lower risk of recurrence. Visual recovery/ improvement occurred in 92% of cases with preoperative visual defects following surgery.

RESUMO

INTRODUCTION: Major trauma centres have improved morbidity and mortality for moderate and severely injured patients. Less injured patients may be treated in facilities less resourced for trauma care. In these units, understanding the variations in injury presentation and treatment over time allows service delivery to be tailored to demand. This study set out to describe seasonal variations in trauma over a 10-year period at a level III trauma unit. MATERIALS AND METHODS: Patient demographics, admission frequency, site of injury, season of admission, management, complications, onward transfers, and length of stay were extracted on consecutive patients admitted with traumatic injuries between January 2009 and December 2018 and recorded on a prospectively maintained database. Analysis was undertaken to determine if there were reproducible patterns in trauma presentation across seasons, based on the patient's age and gender, type of injury, management and length of stay. RESULTS: There were 13,007 'first admissions' over 10 years, with a mean (SD) age of 55.6 (27.7) years. Admissions were higher in summer (27%) and lower in winter (23.6%) and patients were on average younger in the summer (52.8 years) and older in winter (59.2 years). The proportion of female and male patients remained relatively constant across seasons (CV=6% and 8%, respectively). There was seasonal variation in the incidence of forearm (36%) elbow (19%), and multi-sites injuries (17%) compared with hip and wrist injuries (CV=5% for both). A lower proportion of patients underwent operations in summer (72%) compared with other seasons with winter having the highest at 77%. More patients aged less than 60 years stayed in hospital during winter than summer (13.2% vs. 11.6-12.4%) although often for a day. Patients aged 60 years stayed longer in spring and winter. CONCLUSION: The results of this study demonstrate trends in the admission and management of trauma patients to a level III trauma unit. Some of the patterns in admission, treatment and length of stay had not been identified previously. The results can be used to enhance patient care and minimise health care costs by reducing unwarranted variations and enabling service delivery to match the demand in all trauma units.

RESUMO

Exercise can improve cancer-related fatigue, quality of life and physical fitness, but is understudied in less common cancers such as multiple myeloma. Studying less common cancers and the adoption of novel study designs and open-science practices would improve the generalisability, transparency, rigour, credibility and reproducibility of exercise oncology research.

RESUMO

BACKGROUND: Amputations are associated with markedly reduced long-term survival in patients with diabetic foot disease. However, there is paucity of long-term survival data in published literature. METHODS: We searched the electronic case records and laboratory details of patients who underwent amputations between 1997 and 2006 to obtain at least 10 years of follow up data after the surgery to assess the survival rates and possible risk factors reducing survival in the year 2016. Amputation level below ankle was considered as minor and above ankle as major amputations. RESULTS: Of the 233 cases (159 males; median age 68 years), 161 had major amputations. Of the 72 cases who had minor amputations initially, 63 needed a further amputation or contralateral amputation on follow up. One hundred seventy-seven patients (76%) were not alive after 10 years of follow up. The survival rates at 1, 3, 5, 7, and ≥10 years were 64%, 50%, 40%, 34%, and 24%, respectively. Maximum number of deaths occurred within 4 months of amputations. There was no difference between survival rates following major or minor amputations and among males or females. The only statistically significant parameter affecting lower survival rate was age ≥70 years, with each additional year of age increasing the hazard by a factor of 1.039 (95% CI: 1.024-1.054) or 3.9% (2.4-5.4%). CONCLUSIONS: Five-year and 10-year survival rates were 40% and 24%, respectively, following diabetic foot amputations. Higher age ≥70 years was associated with lower survival rate compared with younger age groups after lower extremity amputations.

RESUMO

BACKGROUND: Adolescent girls in the UK and Ireland are failing to meet current physical activity guidelines. Physical activity behaviours track from childhood to adulthood and it is important that adolescent girls are provided with opportunities to be physically active. Walking has been a central focus for physical activity promotion in adults and may effectively increase physical activity levels among younger people. Following on from a pilot feasibility trial, the purpose of this cluster randomised controlled trial (c-RCT) is to evaluate the effectiveness of a novel, low-cost, peer-led school-based walking intervention delivered across the school year at increasing physical activity levels of adolescent girls. METHODS: The Walking In ScHools (WISH) Study is a school-based c-RCT conducted with girls aged 12-14 years from eighteen schools across the Border Region of Ireland / Northern Ireland. Following baseline data collection, schools will be randomly allocated to intervention or control group. In intervention schools, female pupils aged 15-18 years will be invited to train as walk leaders and will lead younger pupils in 10-15 min walks before school, at break and lunch recess. All walks will take place in school grounds and pupils will be encouraged to participate in as many walks as possible each week. The intervention will be delivered for the whole school year (minimum 20-22 weeks). The primary outcome measure is accelerometer-measured total physical activity (counts per minute) (end of intervention). Secondary outcomes will include time spent in sedentary behaviour, light, moderate and vigorous intensity physical activity, anthropometry measures, social media usage and sleep. A mixed-methods process evaluation will also be undertaken. DISCUSSION: The WISH Study will examine the effectiveness of a low-cost, school-based, peer-led walking intervention in increasing physical activity in adolescent girls when delivered across the school year. If the intervention increases physical activity, it would benefit adolescent girls in the defined target area with potential for wider adoption by schools across the UK and Ireland. TRIAL REGISTRATION: ISRCTN; ISRCTN12847782; Registered 2nd July 2019.

RESUMO

The primary means of disseminating sport and exercise science research is currently through journal articles. However, not all studies, especially those with null findings, make it to formal publication. This publication bias towards positive findings may contribute to questionable research practices. Preregistration is a solution to prevent the publication of distorted evidence resulting from this system. This process asks authors to register their hypotheses and methods before data collection on a publicly available repository or by submitting a Registered Report. In the Registered Report format, authors submit a stage 1 manuscript to a participating journal that includes an introduction, methods, and any pilot data indicating the exploratory or confirmatory nature of the study. After a stage 1 peer review, the manuscript can then be offered in-principle acceptance, rejected, or sent back for revisions to improve the quality of the study. If accepted, the project is guaranteed publication, assuming the authors follow the data collection and analysis protocol. After data collection, authors re-submit a stage 2 manuscript that includes the results and discussion, and the study is evaluated on clarity and conformity with the planned analysis. In its final form, Registered Reports appear almost identical to a typical publication, but give readers confidence that the hypotheses and main analyses are less susceptible to bias from questionable research practices. From this perspective, we argue that inclusion of Registered Reports by researchers and journals will improve the transparency, replicability, and trust in sport and exercise science research.

RESUMO

BACKGROUND: High levels of sedentary behavior may negatively affect health outcomes in cancer survivors. A systematic review and meta-analysis was performed to clarify whether postdiagnosis sedentary behavior is related to survival, patient-reported outcomes, and anthropometric outcomes in cancer survivors. METHODS: The Ovid MEDLINE, EMBASE, CINAHL (The Cumulative Index to Nursing and Allied Health Literature), and SPORTDiscus databases were searched from study inception to June 2019. Studies of adults who had been diagnosed with cancer that examined the association between sedentary behavior and mortality, patient-reported outcomes (eg, fatigue, depression), or anthropometric outcomes (eg, body mass index, waist circumference) were eligible for inclusion. Meta-analyses were performed to estimate hazard ratios for the highest compared with the lowest levels of sedentary behavior for all-cause and colorectal cancer-specific mortality outcomes. The ROBINS-E (Risk of Bias in Nonrandomized Studies-of Exposures tool) and the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) system were used to assess the risk of bias and the strength of evidence, respectively. RESULTS: Thirty-three eligible publications from a total of 3569 identified articles were included in the review. A higher level of postdiagnosis sedentary behavior was associated with an increased risk of all-cause mortality (hazard ratio, 1.22; 95% CI, 1.06-1.41; heterogeneity [I2 statistic], 33.8%) as well as colorectal cancer-specific mortality (hazard ratio, 1.53; 95% CI, 1.14-2.06; I2 , 0%). No clear or consistent associations between sedentary behavior and patient-reported or anthropometric outcomes were identified. The risk of bias in individual studies ranged from moderate to serious, and the strength of evidence ranged from very low to low. CONCLUSIONS: Although avoiding high levels of sedentary behavior after a cancer diagnosis may improve survival, further research is required to help clarify whether the association is causal.

RESUMO

BACKGROUND: Public health guidelines suggest that physical activity can be accumulated in multiple short bouts dispersed through the day. A synthesis of the evidence for this approach is lacking. OBJECTIVE: Our objective was to undertake a systematic review and meta-analysis to examine if exercise interventions consisting of a single bout of exercise compared with interventions comprising the same total duration, mode, and intensity of exercise accumulated over the course of the day have different effects on health outcomes in adults. METHODS: Six electronic databases were searched (Jan 1970-29 August 2018). Two authors identified studies that evaluated the effects of a single bout of exercise compared with the same intensity, total duration, and mode of exercise accumulated in multiple bouts over the course of a day, in community-dwelling adults. Risk of bias was assessed using the Cochrane Collaboration tool. Pooled effects were reported as standardised mean differences (MDs) and 95% confidence intervals (CIs) using a random effects model. RESULTS: A total of 19 studies involving 1080 participants met the inclusion criteria. There were no differences between accumulated and continuous groups for any cardiorespiratory fitness or blood pressure outcomes. A difference was found in body mass changes from baseline to post-intervention in favour of accumulated exercise compared with continuous (MD - 0.92 kg, 95% CI - 1.59 to - 0.25, I2 = 0%; five studies, 211 participants). In subgroup analyses, accumulating > 150 min of weekly exercise in multiple bouts per day resulted in small effects on body fat percentage (combined post-intervention and change from baseline values: MD - 0.87%, 95% CI - 1.71 to - 0.04, I2 = 0%; three studies, 166 participants) compared with 150 min of exercise amassed via single continuous bouts per day. There was a decrease in low-density lipoprotein (LDL) cholesterol with accumulated versus continuous exercise (MD - 0.39 mmol/l, 95% CI - 0.73 to - 0.06, I2 = 23%; two studies, 41 participants). No differences were observed for any other blood biomarker (total cholesterol, high-density lipoprotein cholesterol, triglycerides, fasting blood glucose, and fasting insulin). CONCLUSIONS: There is no difference between continuous and accumulated patterns of exercise in terms of effects on fitness, blood pressure, lipids, insulin and glucose. There is some evidence from a small number of studies that changes in body mass and LDL cholesterol are more favourable following the accumulated condition. Collectively our findings suggest that adults are likely to accrue similar health benefits from exercising in a single bout or accumulating activity from shorter bouts throughout the day. This review will inform public health guidelines for physical activity at the global and national levels (PROSPERO 2016 CRD42016044122).

RESUMO

BACKGROUND: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy, affecting 4-12% of reproductive-aged women. Women with PCOS often exhibit many metabolic abnormalities that are associated with an increased cardiovascular disease (CVD) risk, independent of obesity. Exercise interventions from 12 to 24 weeks have been shown to have positive effects on blood lipid profile, ovulation and insulin resistance in women with PCOS. However, no consensus on which exercise interventions are effective (i.e. duration, type of exercise, frequency), including for different phenotypes, currently exists. The aim of this systematic review and meta-analysis is to define effective types of exercise interventions to improve cardiometabolic profile, across the range of phenotypes of PCOS. METHODS: We will conduct electronic database searches, including randomised-controlled trials (RCT), quasi-RCT and clinical trials. Primary outcomes sought will be lipid profile, carotid-intima media thickness, fasting blood glucose, %HbA1c, blood pressure, waist circumference, waist-to-hip ratio, abdominal adiposity and inflammation markers. Secondary outcomes sought will be free and total testosterone, sex hormone binding globulin and insulin resistance. The Cochrane Risk Assessment Tool will be used to assess study quality. Data will be analysed in RevMan. Analysis of heterogeneity will be undertaken using the I2 statistic. Significant heterogeneity will be explored, and sensitivity analyses carried out as appropriate. A subgroup analysis based on androgen profile will be undertaken if data are sufficient. DISCUSSION: A large proportion of women are affected by PCOS. It is prudent to examine how CVD risk can be mitigated in this high-risk population, and this review aims to provide evidence-driven recommendations on the types of exercise interventions that are effective for this. The review will seek to provide recommendations regarding type, frequency and duration of exercise interventions to improve cardiometabolic profile in PCOS. The subgroup analysis may be able to highlight difference in intervention effects between normo-androgenic and hyper-androgenic profile. Limitations include heterogeneity across studies and a scarcity of clinical trials involving a PCOS control group not undertaking any intervention.

RESUMO

We aimed to examine the evidence for the proposed additive effect of exercise in the presence of nature (green exercise) by systematically reviewing studies that investigated the effects of outdoor or virtual green exercise compared with indoor exercise. Our review updates an earlier review, whose searches were conducted in April 2010. Trials were eligible if: (a) participants in an outdoor or virtual exercise condition were exposed to views of nature (green exercise); (b) green exercise was compared with indoor exercise with no exposure to nature; (c) included an outcome related to physical or mental health; (d) used comparative or crossover trial design. We searched the following databases from 1st January 2010 to 28th June 2018: PubMed, CENTRAL, EMBASE, PsycINFO, GreenFile, and Sports DISCUS. We assessed risk of bias using the Cochrane "risk of bias" tool. Where possible we conducted a meta-analysis using the inverse variance random-effects method, and where this approach was not possible we presented the results qualitatively and in harvest plots. We identified 28 eligible trials. In a meta-analysis of just three longitudinal trials, the only statistical finding was slightly lower post-intervention perceived exertion with green versus indoor exercise (mean difference: -1.02; 95% confidence intervals: -1.88, -0.16). Compared with indoor exercise, acute bouts of outdoor green exercise may favorably influence affective valence and enjoyment, but not emotion, perceived exertion, exercise intensity, and biological markers. No other consistent statistical differences were observed, apart from a higher enjoyment of outdoor green versus virtual green exercise. We found a high risk of bias across trials and an overall low quality of evidence. In conclusion, there was limited evidence to support the view that green exercise offers superior benefits to exercise without exposure to nature. The low quality of evidence prohibits clear interpretation of trial findings. Future robust and rigorously designed trials are needed to evaluate the effects of long-term and multiple-bout exposure to nature during exercise compared with exercise indoors.
