RESUMO
BACKGROUND: Assessment of male lower urinary tract symptoms (LUTS) needs to identify predictors of symptom outcomes when interventional treatment is planned. OBJECTIVE: To develop a novel prediction model for prostate surgery outcomes and validate it using a separate patient cohort and derive thresholds for key clinical parameters. DESIGN, SETTING, AND PARTICIPANTS: From the UPSTREAM trial of 820 men seeking treatment for LUTS, analysis of bladder diary (BD), International Prostate Symptom Score (IPSS), IPSS-quality of life, and uroflowmetry data was performed for 176 participants who underwent prostate surgery and provided complete data. For external validation, data from a retrospective database of surgery outcomes in a Japanese urology department (n = 227) were used. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Symptom improvement was defined as a reduction in total IPSS of ≥3 points. Multiple logistic regression, classification tree analysis, and random forest models were generated, including versions with and without BD data. RESULTS AND LIMITATIONS: Multiple logistic regression without BD data identified age (p = 0.029), total IPSS (p = 0.0016), and maximum flow rate (Qmax; p = 0.066) as predictors of outcomes, with area under the receiver operating characteristic curve (AUC) of 77.1%. Classification tree analysis without BD data gave thresholds of IPSS <16 and Qmax ≥13 ml/s (AUC 75.0%). The random forest model, which included all clinical parameters except BD data, had an AUC of 94.7%. Internal validation using the bootstrap method showed reasonable AUCs (69.6-85.8%). Analyses using BD data marginally improved the model fits. External validation gave comparable AUCs for logistic regression, classification tree analysis, and random forest models (all without BD; 70.9%, 67.3%, and 68.5%, respectively). Limitations include the significant number of men with incomplete baseline data and limited assessments in the external validation cohort. CONCLUSIONS: Outcomes of prostate surgery can be predicted preoperatively using age, total IPSS, and uroflowmetry data, with prognostic thresholds of 16 for IPSS and 13 ml/s for Qmax. PATIENT SUMMARY: This study identified key preoperative factors that can predict outcomes of prostate surgery for bothersome urinary symptoms, including which patients are at risk of a poor outcome.

BACKGROUND: Completion rates and correspondence to other measures need to be established for the International Consultation on Incontinence Questionnaire (ICIQ) bladder diary (ICIQ-BD) in the assessment of male lower urinary tract symptoms (LUTS). OBJECTIVE: To evaluate ICIQ-BD completion rates, frequency, volume, and sensation reporting for men. DESIGN, SETTING, AND PARTICIPANTS: Baseline data from the Urodynamics for Prostate Surgery Trial; Randomised Evaluation of Assessment Methods (UPSTREAM) randomised controlled trial evaluating 820 men at 26 UK hospitals, looking at the ICIQ-BD, uroflowmetry, International Prostate Symptom Score, and ICIQ symptom score for male LUTS (ICIQ-MLUTS), were assessed. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The ICIQ-BD, IPSS, ICIQ-MLUTS, and uroflowmetry data at baseline obtained from UPSTREAM were assessed. Correlations were analysed by Pearson's correlation coefficient, and comparison between groups were performed using paired or unpaired t tests or Tukey's test. All statistical tests were two sided and the strength of evidence was presented using p values. RESULTS AND LIMITATIONS: Of the participants, 25.0% (205/820) provided complete voiding and bedtime information for 3 d, 41.2% (338/820) omitted bedtime information, and the remainder omitted some or all voiding information. Median values (minimum - maximum) of 24-h, daytime, and night-time frequencies were 9.7 (3.3-24.0), 7.7 (3.3-22.7), and 1.7 (0.0-5.7), respectively. The mean voided volume per micturition for day and night times were 175.8 ± 74.2 and 264.4 ± 150.7 ml (p < 0.001), respectively. For fully completed diaries, day- and night-time frequency showed a weak-to-moderate correlation with symptom score questionnaires. More severe nocturia was generally reported in symptom scores than in the ICIQ-BD. In patients with high bother for increased daytime frequency (symptom), the mean daytime frequency (ICIQ-BD) was 9.6 ± 3.2 versus 7.6 ± 2.2 for low bother (p < 0.001). High bother for nocturia showed night-time frequency of 2.3 ± 1.2 versus 1.5 ± 1.1 for low bother (p < 0.001). For fully and partially completed diaries, ICIQ-BD sensation scores correlated weakly with symptom scores. Voided volumes from the bladder diary and uroflowmetry correlated weakly. CONCLUSIONS: Two-thirds of men (543/820) fully completed voiding information in the ICIQ-BD, but many omitted bedtime information, limiting the ability to quantify nocturia and diagnose nocturnal polyuria. PATIENT SUMMARY: Most men with urinary symptoms complete a bladder diary fully but may fail to indicate bedtimes. Extra information from a diary helps support symptom questionnaires to explain a patient's urinary habits.

BACKGROUND: Identifying men whose lower urinary tract symptoms (LUTS) may benefit from surgery is challenging. OBJECTIVE: To identify routine diagnostic and urodynamic measures associated with treatment decision-making, and outcome, in exploratory analyses of the UPSTREAM trial. DESIGN, SETTING, AND PARTICIPANTS: A randomised controlled trial was conducted including 820 men, considering surgery for LUTS, across 26 hospitals in England (ISCTRN56164274). INTERVENTION: Men were randomised to a routine care (RC) diagnostic pathway (n = 393) or a pathway that included urodynamics (UDS) in addition to RC (n = 427). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Men underwent uroflowmetry and completed symptom questionnaires, at baseline and 18 mo after randomisation. Regression models identified baseline clinical and symptom measures that predicted recommendation for surgery and/or surgical outcome (measured by the International Prostate Symptom Score [IPSS]). We explored the association between UDS and surgical outcome in subgroups defined by routine measures. RESULTS AND LIMITATIONS: The recommendation for surgery could be predicted successfully in the RC and UDS groups (area under the receiver operating characteristic curve 0.78), with maximum flow rate (Qmax) and age predictors in both groups. Surgery was more beneficial in those with higher symptom scores (eg, IPSS >16), age <74 yr, Qmax <9.8 ml/s, bladder outlet obstruction index >47.6, and bladder contractility index >123.0. In the UDS group, urodynamic measures were more strongly predictive of surgical outcome for those with Qmax >15, although patient-reported outcomes were also more predictive in this subgroup. CONCLUSIONS: Treatment decisions were informed with UDS, when available, but without evidence of change in the decisions reached. Despite the small group sizes, exploratory analyses suggest that selective use of UDS could detect obstructive pathology, missed by routine measures, in certain subgroups. PATIENT SUMMARY: Baseline clinical and symptom measurements were able to predict treatment decisions. The addition of urodynamic test results, while useful, did not generally lead to better surgical decisions and outcomes over routine tests alone.

Introduction: Polypharmacy is increasingly common, and associated with undesirable consequences. Polypharmacy management necessitates balancing therapeutic benefits and risks, and varying clinical and patient priorities. Current guidance for managing polypharmacy is not supported by high quality evidence. The aim of the Improving Medicines use in People with Polypharmacy in Primary Care (IMPPP) trial is to evaluate the effectiveness of an intervention to optimise medication use for patients with polypharmacy in a general practice setting. Methods: This trial will use a multicentre, open-label, cluster-randomised controlled approach, with two parallel groups. Practices will be randomised to a complex intervention comprising structured medication review (including interprofessional GP/pharmacist treatment planning and patient-facing review) supported by performance feedback, financial incentivisation, clinician training and clinical informatics (intervention), or usual care (control). Patients with polypharmacy and triggering potentially inappropriate prescribing (PIP) indicators will be recruited in each practice using a computerised search of health records. 37 practices will recruit 50 patients, and review them over a 26-week intervention delivery period. The primary outcome is the mean number of PIP indicators triggered per patient at 26 weeks follow-up, determined objectively from coded GP electronic health records. Secondary outcomes will include patient reported outcome measures, and health and care service use. The main intention-to-treat analysis will use linear mixed effects regression to compare number of PIP indicators triggered at 26 weeks post-review between groups, adjusted for baseline (pre-randomisation) values. A nested process evaluation will explore implementation of the intervention in primary care. Ethics and dissemination: The protocol and associated study materials have been approved by the Wales REC 6, NHS Research Ethics Committee (REC reference 19/WA/0090), host institution and Health Research Authority. Research outputs will be published in peer-reviewed journals and relevant conferences, and additionally disseminated to patients and the public, clinicians, commissioners and policy makers. ISRCTN Registration: 90146150 (28/03/2019).
RESUMO
BACKGROUND: Lower urinary tract symptoms (LUTS) in men may indicate bladder outlet obstruction (BOO) or weakness, known as detrusor underactivity (DU). Severe bothersome LUTS are a common indication for surgery. The diagnostic tests may include urodynamics (UDS) to confirm whether BOO or DU is the cause, potentially reducing the number of people receiving (inappropriate) surgery. OBJECTIVES: The primary objective was to determine whether a care pathway including UDS is no worse for symptom outcome than one in which it is omitted, at 18 months after randomisation. Rates of surgery was the key secondary outcome. DESIGN: This was a pragmatic, multicentre, two-arm (unblinded) randomised controlled trial, incorporating a health economic analysis and qualitative research. SETTING: Urology departments of 26 NHS hospitals in England. PARTICIPANTS: Men (aged ≥ 18 years) seeking further treatment, potentially including surgery, for bothersome LUTS. Exclusion criteria were as follows: unable to pass urine without a catheter, having a relevant neurological disease, currently undergoing treatment for prostate or bladder cancer, previously had prostate surgery, not medically fit for surgery and/or unwilling to be randomised. INTERVENTIONS: Men were randomised to a care pathway based on non-invasive routine tests (control) or routine care plus invasive UDS (intervention arm). MAIN OUTCOME MEASURES: The primary outcome was International Prostate Symptom Score (IPSS) at 18 months after randomisation and the key secondary outcome was rates of surgery. Additional secondary outcomes included adverse events (AEs), quality of life, urinary and sexual symptoms, UDS satisfaction, maximum urinary flow rate and cost-effectiveness. RESULTS: A total of 820 men were randomised (UDS, 427; routine care, 393). Sixty-seven men withdrew before 18 months and 11 died (unrelated to trial procedures). UDS was non-inferior to routine care for IPSS 18 months after randomisation, with a confidence interval (CI) within the margin of 1 point (-0.33, 95% CI -1.47 to 0.80). A lower surgery rate in the UDS arm was not found (38% and 36% for UDS and routine care, respectively), with overall rates lower than expected. AEs were similar between the arms at 43-44%. There were more cases of acute urinary retention in the routine care arm. Patient-reported outcomes for LUTS improved in both arms and satisfaction with UDS was high in men who received it. UDS was more expensive than routine care. From a secondary care perspective, UDS cost an additional £216 over an 18-month time horizon. Quality-adjusted life-years (QALYs) were similar, with a QALY difference of 0.006 in favour of UDS over 18 months. It was established that UDS was acceptable to patients, and valued by both patients and clinicians for its perceived additional insight into the cause and probable best treatment of LUTS. LIMITATIONS: The trial met its predefined recruitment target, but surgery rates were lower than anticipated. CONCLUSIONS: Inclusion of UDS in the diagnostic tests results in a symptom outcome that is non-inferior to a routine care pathway, but does not affect surgical rates for treating BOO. Results do not support the routine use of UDS in men undergoing investigation of LUTS. FUTURE WORK: Focus should be placed on indications for selective utilisation of UDS in individual cases and long-term outcomes of diagnosis and therapy.

After hospital referral, men with bothersome lower urinary tract symptoms (LUTS) are assessed with standard tests. These include measurement of urine flow rate, bladder diaries and questionnaires, including the International Prostate Symptom Score (IPSS). UPSTREAM (Urodynamics for Prostate Surgery Trial; Randomised Evaluation of Assessment Methods) researched whether or not including an extra test, urodynamics (UDS), helps when considering treatment options. UDS is a more invasive test and measures pressure in the bladder to check whether or not the prostate is causing obstruction. It was presumed that, if there is no obstruction, surgery would not be offered, so that using UDS would reduce the number of prostate operations. Each man participating (820 in total) was assessed with the standard tests. Around half of them had no extra tests (the 'routine care' arm of the trial); the rest had the UDS tests (the 'UDS' arm). Men then went on to have treatment, which they chose having discussed their test results with a urologist. IPSS and other symptom scores were examined for each man 18 months after joining the trial. At 18 months, surgery outcomes were known for 792 men and IPSS was known for 669 men. We investigated if the two trial arms showed similar changes in the IPSS and if there were fewer operations done in the UDS arm. We identified similar reductions in the IPSS in both arms. However, UDS tests did not reduce the number of operations. Analysing all the costs, it was found that a pathway including UDS costs more than routine care. Interviews were conducted that showed that men found UDS acceptable, and that the additional information helped both the men and their doctors consider which treatment would be most appropriate. These results do not support the routine use of UDS in the assessment of every man considering prostate surgery for LUTS. Further exploration of the data may identify circumstances in which UDS could be helpful.

BACKGROUND: Prostate surgery can improve lower urinary tract symptoms (LUTS) by relieving bladder outlet obstruction (BOO). However, surgery is less effective without BOO, or if detrusor underactivity is present. Urodynamics (UDS) can identify BOO and measure detrusor activity, but evidence in clinical practice is lacking. OBJECTIVE: Urodynamics for Prostate Surgery Trial: Randomised Evaluation of Assessment Methods (UPSTREAM) aimed to evaluate whether a care pathway including UDS would reduce surgery without increasing urinary symptoms. DESIGN, SETTING, AND PARTICIPANTS: UPSTREAM is a pragmatic, noninferiority, randomised controlled trial in men with bothersome LUTS, in whom surgery was an option, in 26 hospitals in England (ISRCTN56164274). INTERVENTION: Participants were randomised (1:1) to routine care (RC) diagnostic tests, or RC plus UDS. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was the International Prostate Symptom Score (IPSS; patient-reported outcome scale from 0 to 35 points) 18 mo after randomisation, with a noninferiority margin of 1 point. Urological surgery rates were a key secondary outcome. The primary outcome was compared between the arms using linear regression, analysed on an intention-to-treat basis. RESULTS AND LIMITATIONS: Between October 2014 and December 2016, 820 men (median age 68 yr) were randomised (393 and 427 in the RC and UDS arms, respectively). The UDS arm showed noninferiority of the mean IPSSs (UDS 12.6; RC 13.1; adjusted difference at 18 mo -0.33 [95% confidence interval {CI} -1.47, +0.80]). In the UDS arm, 153/408 (38%) received surgery compared with 138/384 (36%) in the RC arm (adjusted odds ratio 1.05; 95% CI 0.77, 1.43). A total of 428 adverse events (UDS 234; RC 194) were recorded, with related events similar in both arms and 11 unrelated deaths. CONCLUSIONS: In this population, the UDS randomised group was noninferior to RC for the IPSS but did not reduce surgical rates. This study shows that routine use of UDS in the evaluation of uncomplicated LUTS has a limited role and should be used selectively. PATIENT SUMMARY: For men with uncomplicated lower urinary tract symptoms, symptom improvements after treatment and the number of operations performed are similar, irrespective of whether or not urodynamic tests are conducted in addition to routine tests. Accordingly, routine use of urodynamics has a limited role in this population group.

PURPOSE: We established severity banding ranges, bother assessment and key item content in principal patient reported outcomes measures in men seeking therapy for lower urinary tract symptoms. MATERIALS AND METHODS: Data for International Prostate Symptom Score (I-PSS) and International Consultation on Incontinence Questionnaire Male Lower Urinary Tract Symptoms (ICIQ-MLUTS) were derived from a study evaluating 820 men at 26 United Kingdom hospitals. ROC curves were used to establish severity bandings. RESULTS: Classification tree showed that thresholds between mild-moderate and moderate-severe severity bands were 15 and 27 for I-PSS, 16 and 26 for ICIQ-MLUTS/severity, and 22 and 81 for ICIQ-MLUTS/bother, respectively. Highest area under the ROC curve and lowest Akaike's information criteria of univariate logistic regression indicated that ICIQ-MLUTS/bother was more related to global quality of life than were I-PSS and ICIQ-MLUTS/severity. The symptoms affecting I-PSS-quality of life (QoL) were only fully identified by ICIQ-MLUTS, because 2 key symptoms (urinary incontinence and post-micturition dribble) are not measured by I-PSS. ICIQ-MLUTS demonstrated that bother of some lower urinary tract symptoms is disproportionate to severity, and that persisting high bother levels following surgery are more likely due to storage (18% to 25%) and post-voiding (18% to 28%) lower urinary tract symptoms than voiding lower urinary tract symptoms (5% to 13%). Symptom improvement after surgery was uncertain if baseline I-PSS-QoL score was less than 3. CONCLUSIONS: The severity threshold scores were measured for the 2 key lower urinary tract symptoms patient reported outcomes measures, and the results indicate suitable categories of symptom severity for use in men referred for urological care. The ICIQ-MLUTS measures all the lower urinary tract symptoms affecting quality of life and includes individual symptom bother scores.

OBJECTIVES: To investigate whether decreased otoacoustic emission (OAE) signal recordings in the right ear are associated with an increased risk of sudden infant death syndrome (SIDS) and to monitor any temporal changes in risk factors. DESIGN: Retrospective case-control study. SETTING: Telephone interviews with families recruited in England between July 2016 and October 2017 who experienced the unexpected death of a child <4 years old since 2008 and control families recruited from maternity wards in Bristol and Birmingham. PARTICIPANTS: We recruited 91 (89%) of the 102 bereaved families who made initial contact, 64 deaths were under 1 year (sudden unexpected death in infancy) of which 60 remained unexplained (SIDS). Of the 220 control families, 194 (88%) follow-up interviews were conducted. We had analysable hearing data for 24 SIDS infants (40%) and 98 controls (51%). RESULTS: OAE signals were marginally increased rather than decreased among SIDS infants for the right ear, especially at lower frequencies, but not significantly so. The strongest predictors of SIDS were bed-sharing in hazardous (infant sleeping next to a carer who smoked, drank alcohol or slept on a sofa) circumstances (35% vs 3% controls, p<0.0001), infants found prone (33% vs 3% controls, p<0.0001) and infants whose health in the final week was 'not good' (53% vs 9% controls, p<0.0001). The prevalence of maternal smoking during pregnancy among both SIDS mothers (20%) and controls (10%) was much lower than previous studies. CONCLUSIONS: Hearing data were difficult to obtain; larger numbers would be needed to determine if asymmetrical differences between the right and left ear were a marker for SIDS. A national prospective registry for monitoring and a renewed campaign to a new generation of parents needs to be considered underlining the initial message to place infants on their backs for sleep and the more recent message to avoid bed-sharing in hazardous circumstances.

Breastfeeding and the place of sleep for the mother and the infant have been controversial internationally due to reported concerns regarding infant deaths despite the known benefits of exclusive and prolonged breastfeeding, which are increased by breastfeeding at night. The aims of this integrated analysis were to (a) review breastfeeding and maternal and infant sleep research literature via historical, epidemiological, anthropological, and methodological lenses; (b) use this information to determine where we are currently in safeguarding both infant lives and breastfeeding; and (c) postulate the direction that research might take from this point forward to improve our knowledge and inform our policy and practice. Despite well-meaning but unsuccessful campaigns in some countries to dissuade parents from sleeping with their babies, many breastfeeding mothers and caregivers do sleep with their infants whether intentionally or unintentionally. Taking cultural contexts and socio-ecological circumstances into consideration, data supports policies to counsel parents and caregivers on safe sleep practices, including bed-sharing in non-hazardous circumstances, particularly in the absence of parental smoking, recent parental alcohol consumption, or sleeping next to an adult on a sofa. Further research with appropriate methodology is needed to drill down on actual rates of infant deaths, paying close attention to the definitions of deaths, the circumstances of the deaths, and confounding factors, in order to ensure we have the best information with which to derive public health policy. Introduction and use of the concept of "breastsleeping" is a plausible way to remove the negative connotations of "co-sleeping" and redirect ongoing data-driven discussions and education of best practices of breastfeeding and sleep.

BACKGROUND: Clinical evaluation of male lower urinary tract symptoms (MLUTS) in secondary care uses a range of assessments. It is unknown how MLUTS evaluation influences outcome of therapy recommendations and choice, notably urodynamics (UDS; filling cystometry and pressure flow studies). OBJECTIVE: To report participants' sociodemographic and clinical characteristics, and initial diagnostic findings of the Urodynamics for Prostate Surgery Trial; Randomised Evaluation of Assessment Methods (UPSTREAM). UPSTREAM is a randomised controlled trial evaluating whether symptoms are noninferior and surgery rates are lower if UDS is included. DESIGN, SETTING, AND PARTICIPANTS: A total of 820 men (≥18 yr of age) seeking treatment for bothersome LUTS were recruited from 26 National Health Service hospital urology departments. INTERVENTION: Care pathway based on routine, noninvasive tests (control) or routine care plus UDS (intervention arm). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome is International Prostate Symptom Score (IPSS) and the key secondary outcome is surgery rates 18 mo after randomisation. International Consultation on Incontinence Questionnaires were captured for MLUTS, sexual function, and UDS satisfaction. Baseline clinical and patient-reported outcome measures (PROMs), and UDS findings were informally compared between arms. Trends across age groups for urinary and sexual PROMs were evaluated with a Cuzick's test, and questionnaire items were compared using Pearson's correlation coefficient. RESULTS AND LIMITATIONS: Storage LUTS, notably nocturia, and impaired sexual function are prominent in men being assessed for surgery. Sociodemographic and clinical evaluations were similar between arms. Overall mean IPSS and quality of life scores were 18.94 and 4.13, respectively. Trends were found across age groups, with older men suffering from higher rates of incontinence, nocturia, and erectile dysfunction, and younger men suffering from increased daytime frequency and voiding symptoms. Men undergoing UDS testing expressed high satisfaction with the procedure. CONCLUSIONS: Men being considered for surgery have additional clinical features that may affect treatment decision making and outcomes, notably storage LUTS and impaired sexual function. PATIENT SUMMARY: We describe initial assessment findings from a large clinical study of the treatment pathway for men suffering with bothersome urinary symptoms who were referred to hospital for further treatment, potentially including surgery. We report the patient characteristics and diagnostic test results, including symptom questionnaires, bladder diaries, flow rate tests, and urodynamics.

This review aimed to better understand the underlying physiology of the risks and benefits of bed-sharing. Eight databases were searched using terms relating to adult-infant/baby, bed-sharing/co-sleeping combined with outcome terms for physiology, sleep, cardiovascular, respiratory, temperature and behaviour. Of 836 papers identified, 59 papers representing 48 cohorts met inclusion criteria. Objective data using various methodologies were available in 27 papers and subjective data in 32 papers. Diverse measures were reported using variable definitions of bed-sharing. Identified physiological and behavioural differences between bed-sharing and cot-sleeping included increased behavioural arousals, warmer in-bed temperatures and increased breastfeeding duration in bedshare infants as well as differences in infant overnight sleep architecture, cardiorespiratory control and cortisol responses to stress. We concluded that many differences are context-specific, and dependent on the subjective view of the parents and their cultural values. Objective risk arises if the infant is unable to mount an appropriate physiological or behavioural response to their micro-environment. More studies in the bed-sharing setting are needed to identify infant risk, the potential benefits of a safer environment, and how bed-sharing interacts with infant care practices other than sleep.

BACKGROUND: Most adolescent girls in the UK do not meet government physical activity recommendations and effective interventions are needed. This study reports the results of a feasibility trial of PLAN-A, a novel school-based peer-led physical activity intervention for adolescent girls. METHODS: A two-arm cluster randomised controlled feasibility study was conducted in six English secondary schools (4 intervention & 2 control). Year 8 (age 12-13) girls were eligible and randomisation was at school-level. The intervention involved training Year 8 girls (out of school for two consecutive days, plus one top-up day 5 weeks later), who were identified by their peers as influential, to provide informal support to their friends to increase their physical activity. Feasibility of the intervention and the research was examined, including: recruitment, training attendance and data provision rates, evidence of promise of the intervention to affect weekday moderate-to-vigorous physical activity (MVPA), intervention cost and estimation of the sample size for a definitive trial. Accelerometer and questionnaire data were collected at the beginning of Year 8 (Time 0), the end of Year 8 (10-weeks after peer-supporter training) and the beginning of Year 9 (Time 2). RESULTS: Four hundred twenty-seven girls were recruited (95% recruitment rate). 55 girls consented to be a peer-supporter and 53 peer-supporters were trained (97% of those invited). Accelerometer return rates exceeded 85% at each time point and wear time criteria was met by 83%, 71% and 62% participants at Time 0, 1 and 2 respectively. Questionnaire data were provided by >91% of participants at each time point. Complete-case adjusted linear regression analysis showed evidence of a 6.09 minute (95% CI = 1.43, 10.76) between-arms difference in weekday MVPA at Time 2 in favour of the intervention arm. On average PLAN-A cost £2685 per school to deliver (£37 per Year 8 girl). There were no adverse events. A trial involving 20 schools would be adequately powered to detect a between-arms difference in weekday MVPA of at least six minutes. CONCLUSIONS: The PLAN-A intervention adopts a novel peer-led approach, is feasible, and shows evidence of promise to positively affect girls' physical activity levels. A definitive trial is warranted. TRIAL REGISTRATION: ISCTRN, ISRCTN12543546, Registered on 28/7/2015, URL of registry record: http://www.isrctn.com/ISRCTN12543546.

OBJECTIVE/BACKGROUND: Sleep abnormalities are characteristic of chronic fatigue syndrome (CFS, also known as 'ME'), however it is unknown whether sleep might be a causal risk factor for CFS/ME. PATIENTS/METHODS: We analysed data from the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort. We describe sleep patterns of children aged 6 months to 11 years, who were subsequently classified as having (or not having) 'chronic disabling fatigue' (CDF, a proxy for CFS/ME) between the ages 13 and 18 years, and we investigated the associations of sleep duration at age nine years with CDF at age 13 years, as well as sleep duration at age 11 years with CDF at age 16 years. RESULTS: Children who had CDF during adolescence had shorter night-time sleep duration from 6 months to 11 years of age, and there was strong evidence that difficulties in going to sleep were more common in children who subsequently developed CDF. The odds of CDF at age 13 years were 39% lower (odds ratio (OR) = 0.61, 95% CI = 0.43, 0.88) for each additional hour of night-time sleep at age nine years, and the odds of CDF at age 16 years were 51% lower (OR = 0.49, 95% CI = 0.34, 0.70) for each additional hour of night-time sleep at age 11 years. Mean night-time sleep duration at age nine years was 13.9 (95% CI = 3.75, 24.0) minutes shorter among children who developed CDF at age 13 years, and sleep duration at age 11 years was 18.7 (95% CI = 9.08, 28.4) minutes shorter among children who developed CDF at age 16 (compared with children who did not develop CDF at 13 and 16 years, respectively). CONCLUSIONS: Children who develop chronic disabling fatigue in adolescence have shorter night-time sleep duration throughout early childhood, suggesting that sleep abnormalities may have a causal role in CFS/ME or that sleep abnormalities and CFS/ME are associated with a common pathophysiological cause.

BACKGROUND: Current management for men with lower urinary tract symptoms (LUTS) is a pathway that results in prostate surgery in a significant proportion. While helpful in relieving benign prostatic obstruction (BPO), surgery may be ineffective for men suffering from difficulties not relating to BPO. The UPSTREAM trial started recruitment in October 2014 with the aim of establishing whether a care pathway including urodynamics (a diagnostic tool for BPO and thus an indication of whether surgery is needed) is no worse for men, in terms of symptomatic outcome, than one without (routine care). METHODS/DESIGN: This analysis plan outlines the main outcomes of the study and specific design choices, such as non-inferiority margins. The trial is currently recruiting in 26 hospitals across the UK, randomising men to either urodynamics or routine care, with recruitment set to end on the 31 December 2016. All outcomes will be measured 18 months after randomisation to allow sufficient time for surgical procedures and recovery. The primary outcome is based on a non-inferiority design with a margin of 1 point on the International Prostate Symptom Score (IPSS) scale. The key secondary outcome for this trial is surgery rate per arm, which is estimated to be at least 18% lower in the urodynamics arm. Surgery rates, adverse events, flow rate, urinary symptoms and sexual symptoms are secondary outcomes to be assessed for superiority. This is an update to the UPSTREAM protocol, which has already been published in this journal. DISCUSSION: This a priori statistical analysis plan aims to reduce reporting bias by allowing access to the trial's objectives and plans in advance of recruitment end. The results of the trial are expected to be published soon after the trial end date of 30 September 2018. TRIAL REGISTRATION: ISRCTN registry, ISRCTN56164274 . Registered on 8 April 2014.

OBJECTIVE: Qualitative interviews with mothers of babies at higher risk of sudden infant death syndrome (SIDS) were carried out to understand their views and decision-making process on the infant sleep environment and safe sleep messages. DESIGN AND SETTING: Twenty semi-structured interviews were conducted between February and November 2014 in deprived areas of Bristol, UK. Mothers were asked about their decision-making for the infant sleep environment and safe sleep messages including infant sleep position, co-sleeping, smoking, dummy use, feeding and disrupted routines. The interviews were transcribed, coded and thematic analysis carried out. PARTICIPANTS: Participants were invited based on an algorithm developed in a previous SIDS case control study that identified an increased risk of SIDS from four demographic characteristics: young maternal age, smoking during pregnancy, three or more children, and a measure of deprivation. The presence of three, or more characteristics led to being invited to take part in the qualitative study. RESULTS: Factors influencing mothers' adherence to the safe sleep messages included previous experience and the credibility of the advice given. They described disrupted routines that led to risky scenarios with a belief that occasional risks were acceptable. Where circumstances made following the advice more difficult they found alternative strategies to reduce the risk, including the use of movement monitors, regular checking and a belief that lighter maternal sleep in the presence of a baby was protective. CONCLUSIONS: Safer sleep messages should be tailored to fit with the lived realities of mothers, especially those at higher risk. The traditional list of 'do's' and 'don'ts' was not well accepted by this group. Interventions that seek to influence this higher-risk group should acknowledge mothers' own protective instincts and consider their beliefs and understanding behind the safer sleep messages if they are to be effective and encourage this group to change.
RESUMO
BACKGROUND: The aim of this study was to examine the effectiveness and cost of an after-school dance intervention at increasing the physical activity levels of Year 7 girls (age 11-12). METHODS: A cluster randomised controlled trial was conducted in 18 secondary schools. Participants were Year 7 girls attending a study school. The Bristol Girls Dance Project (BGDP) intervention consisted of up to forty, 75-minute dance sessions delivered in the period immediately after school by experienced dance instructors over 20-weeks. The pre-specified primary outcome was accelerometer assessed mean minutes of weekday moderate to vigorous physical activity (MVPA) at time 2 (52 weeks are T0 baseline assessments). Secondary outcomes included accelerometer assessed mean minutes of weekday MVPA at time 1 (while the intervention was still running) and psychosocial outcomes. Intervention costs were assessed. RESULTS: 571 girls participated. Valid accelerometer data were collected from 549 girls at baseline with 508 girls providing valid accelerometer data at baseline and time 2. There were no differences between the intervention and control group for accelerometer assessed physical activity at either time 1 or time 2. Only one third of the girls in the intervention arm met the pre-set adherence criteria of attending two thirds of the dance sessions that were available to them. Instrumental variable regression analyses using complier average causal effects provided no evidence of a difference between girls who attended the sessions and the control group. The average cost of the intervention was £73 per girl, which was reduced to £63 when dance instructor travel expenses were excluded. CONCLUSION: This trial showed no evidence that an after-school dance programme can increase the physical activity of Year 7 girls. The trial highlighted the difficulty encountered in maintaining attendance in physical activity programmes delivered in secondary schools. There is a need to find new ways to help adolescent girls to be physically active via identifying ways to support and encourage sustained engagement in physical activity over the life course. TRIAL REGISTRATION: ISRCTN52882523.

OBJECTIVE: Sleeping on sofas increases the risk of sudden infant death syndrome and other sleep-related deaths. We sought to describe factors associated with infant deaths on sofas. METHODS: We analyzed data for infant deaths on sofas from 24 states in 2004 to 2012 in the National Center for the Review and Prevention of Child Deaths Case Reporting System database. Demographic and environmental data for deaths on sofas were compared with data for sleep-related infant deaths in other locations, using bivariate and multivariable, multinomial logistic regression analyses. RESULTS: A total of 1024 deaths on sofas made up 12.9% of sleep-related infant deaths. They were more likely than deaths in other locations to be classified as accidental suffocation or strangulation (adjusted odds ratio [aOR] 1.9; 95% confidence interval [CI], 1.6-2.3) or ill-defined cause of death (aOR 1.2; 95% CI, 1.0-1.5). Infants who died on sofas were less likely to be Hispanic (aOR 0.7; 95% CI, 0.6-0.9) compared with non-Hispanic white infants or to have objects in the environment (aOR 0.6; 95% CI, 0.5-0.7) and more likely to be sharing the surface with another person (aOR 2.4; 95% CI, 1.9-3.0), to be found on the side (aOR 1.9; 95% CI, 1.4-2.4), to be found in a new sleep location (aOR 6.5; 95% CI, 5.2-8.2), and to have had prenatal smoke exposure (aOR 1.4; 95% CI, 1.2-1.6). Data on recent parental alcohol and drug consumption were not available. CONCLUSIONS: The sofa is an extremely hazardous sleep surface for infants. Deaths on sofas are associated with surface sharing, being found on the side, changing sleep location, and experiencing prenatal tobacco exposure, which are all risk factors for sudden infant death syndrome and sleep-related deaths.

Mortality from sudden infant death syndrome (SIDS) has decreased substantially from the late 1980s. This has been attributed to the change in infant sleep position initially from prone (front) to side and then to predominantly supine (back). We calculate that this has saved over 3000 lives. However, we argue that we could save more infant lives, if more focus was given to the risks observed from parents sleeping in the same bed as their babies.
