Sleep and motor learning in stroke (SMiLES): a longitudinal study investigating sleep-dependent consolidation of motor sequence learning in the context of recovery after stroke.

INTRODUCTION: There is growing evidence that sleep is disrupted after stroke, with worse sleep relating to poorer motor outcomes. It is also widely acknowledged that consolidation of motor learning, a critical component of poststroke recovery, is sleep-dependent. However, whether the relationship between disrupted sleep and poor outcomes after stroke is related to direct interference of sleep-dependent motor consolidation processes, is currently unknown. Therefore, the aim of the present study is to understand whether measures of motor consolidation mediate the relationship between sleep and clinical motor outcomes post stroke. METHODS AND ANALYSIS: We will conduct a longitudinal observational study of up to 150 participants diagnosed with stroke affecting the upper limb. Participants will be recruited and assessed within 7 days of their stroke and followed up at approximately 1 and 6 months. The primary objective of the study is to determine whether sleep in the subacute phase of recovery explains the variability in upper limb motor outcomes after stroke (over and above predicted recovery potential from the Predict Recovery Potential algorithm) and whether this relationship is dependent on consolidation of motor learning. We will also test whether motor consolidation mediates the relationship between sleep and whole-body clinical motor outcomes, whether motor consolidation is associated with specific electrophysiological sleep signals and sleep alterations during subacute recovery. ETHICS AND DISSEMINATION: This trial has received both Health Research Authority, Health and Care Research Wales and National Research Ethics Service approval (IRAS: 304135; REC: 22/LO/0353). The results of this trial will help to enhance our understanding of the role of sleep in recovery of motor function after stroke and will be disseminated via presentations at scientific conferences, peer-reviewed publication, public engagement events, stakeholder organisations and other forms of media where appropriate.

Improving sleep after stroke: A randomised controlled trial of digital cognitive behavioural therapy for insomnia.

Stroke is frequently accompanied by long-term sleep disruption. We therefore aimed to assess the efficacy of digital cognitive behavioural therapy for insomnia to improve sleep after stroke. A parallel group randomised controlled trial was conducted remotely in participant's homes/online. Randomisation was online with minimisation of between-group differences in age and baseline Sleep Condition Indicator-8 score. In total, 86 community-dwelling stroke survivors consented, of whom 84 completed baseline assessments (39 female, mean 5.5 years post-stroke, mean 59 years old), and were randomised to digital cognitive behavioural therapy or control (sleep hygiene information). Follow-up was at post-intervention (mean 75 days after baseline) and 8 weeks later. The primary outcome was self-reported insomnia symptoms, as per the Sleep Condition Indicator-8 (range 0-32, lower numbers indicate more severe insomnia, reliable change 7 points) at post-intervention. There were significant improvements in Sleep Condition Indicator-8 for digital cognitive behavioural therapy compared with control (intention-to-treat, digital cognitive behavioural therapy n = 48, control n = 36, 5 imputed datasets, effect of group p ≤ 0.02, η p 2 = 0.07-0.12 [medium size effect], pooled mean difference = -3.35). Additionally, secondary outcomes showed shorter self-reported sleep-onset latencies and better mood for the digital cognitive behavioural therapy group, but no significant differences for self-efficacy, quality of life or actigraphy-derived sleep parameters. Cost-effectiveness analysis found that digital cognitive behavioural therapy dominates over control (non-significant cost savings and higher quality-adjusted life years). No related serious adverse events were reported to the researchers. Overall, digital cognitive behavioural therapy for insomnia effectively improves sleep after stroke. Future research is needed to assess earlier stages post-stroke, with a longer follow-up period to determine whether it should be included as part of routine post-stroke care.

Nurse-delivered sleep restriction therapy in primary care for adults with insomnia disorder: a mixed-methods process evaluation.

BACKGROUND: Sleep restriction therapy (SRT) is a behavioural therapy for insomnia. AIM: To conduct a process evaluation of a randomised controlled trial comparing SRT delivered by primary care nurses plus a sleep hygiene booklet with the sleep hygiene booklet only for adults with insomnia disorder. DESIGN AND SETTING: A mixed-methods process evaluation in a general practice setting. METHOD: Semi-structured interviews were conducted in a purposive sample of patients receiving SRT, the practice nurses who delivered the therapy, and also GPs or practice managers at the participating practices. Qualitative data were explored using framework analysis, and integrated with nurse comments and quantitative data, including baseline Insomnia Severity Index score and serial sleep efficiency outcomes to investigate the relationships between these. RESULTS: In total, 16 patients, 13 nurses, six practice managers, and one GP were interviewed. Patients had no previous experience of behavioural therapy, needed flexible appointment times, and preferred face-to-face consultations; nurses felt prepared to deliver SRT, accommodating patient concerns, tailoring therapy, and negotiating sleep timings despite treatment complexity and delays between training and intervention delivery. How the intervention produced change was explored, including patient and nurse interactions and patient responses to SRT. Difficulties maintaining SRT, negative attitudes towards treatment, and low self-efficacy were highlighted. Contextual factors, including freeing GP time, time constraints, and conflicting priorities for nurses, with suggestions for alternative delivery options, were raised. Participants who found SRT a positive process showed improvements in sleep efficiency, whereas those who struggled did not. CONCLUSION: SRT was successfully delivered by practice nurses and was generally well received by patients, despite some difficulties delivering and applying the intervention in practice.

Clinical and cost-effectiveness of nurse-delivered sleep restriction therapy for insomnia in primary care (HABIT): a pragmatic, superiority, open-label, randomised controlled trial.

BACKGROUND: Insomnia is prevalent and distressing but access to the first-line treatment, cognitive behavioural therapy (CBT), is extremely limited. We aimed to assess the clinical and cost-effectiveness of sleep restriction therapy, a key component of CBT, which has the potential to be widely implemented. METHODS: We did a pragmatic, superiority, open-label, randomised controlled trial of sleep restriction therapy versus sleep hygiene. Adults with insomnia disorder were recruited from 35 general practices across England and randomly assigned (1:1) using a web-based randomisation programme to either four sessions of nurse-delivered sleep restriction therapy plus a sleep hygiene booklet or a sleep hygiene booklet only. There was no restriction on usual care for either group. Outcomes were assessed at 3 months, 6 months, and 12 months. The primary endpoint was self-reported insomnia severity at 6 months measured with the insomnia severity index (ISI). The primary analysis included participants according to their allocated group and who contributed at least one outcome measurement. Cost-effectiveness was evaluated from the UK National Health Service and personal social services perspective and expressed in terms of incremental cost per quality-adjusted life year (QALY) gained. The trial was prospectively registered (ISRCTN42499563). FINDINGS: Between Aug 29, 2018, and March 23, 2020 we randomly assigned 642 participants to sleep restriction therapy (n=321) or sleep hygiene (n=321). Mean age was 55·4 years (range 19-88), with 489 (76·2%) participants being female and 153 (23·8%) being male. 580 (90·3%) participants provided data for at least one outcome measurement. At 6 months, mean ISI score was 10·9 (SD 5·5) for sleep restriction therapy and 13·9 (5·2) for sleep hygiene (adjusted mean difference -3·05, 95% CI -3·83 to -2·28; p<0·0001; Cohen's d -0·74), indicating that participants in the sleep restriction therapy group reported lower insomnia severity than the sleep hygiene group. The incremental cost per QALY gained was £2076, giving a 95·3% probability that treatment was cost-effective at a cost-effectiveness threshold of £20 000. Eight participants in each group had serious adverse events, none of which were judged to be related to intervention. INTERPRETATION: Brief nurse-delivered sleep restriction therapy in primary care reduces insomnia symptoms, is likely to be cost-effective, and has the potential to be widely implemented as a first-line treatment for insomnia disorder.

Improving sleep and learning in rehabilitation after stroke, part 2 (INSPIRES2): study protocol for a home-based randomised control trial of digital cognitive behavioural therapy (dCBT) for insomnia.

INTRODUCTION: Consolidation of motor skill learning, a key component of rehabilitation post-stroke, is known to be sleep dependent. However, disrupted sleep is highly prevalent after stroke and is often associated with poor motor recovery and quality of life. Previous research has shown that digital cognitive behavioural therapy (dCBT) for insomnia can be effective at improving sleep quality after stroke. Therefore, the aim of this trial is to evaluate the potential for sleep improvement using a dCBT programme, to improve rehabilitation outcomes after stroke. METHODS AND ANALYSIS: We will conduct a parallel-arm randomised controlled trial of dCBT (Sleepio) versus treatment as usual among individuals following stroke affecting the upper limb. Up to 100 participants will be randomly allocated (2:1) into either the intervention (6-8 week dCBT) or control (continued treatment as usual) group. The primary outcome of the study will be change in insomnia symptoms pre to post intervention compared with treatment as usual. Secondary outcomes include improvement in overnight motor memory consolidation and sleep measures between intervention groups, correlations between changes in sleep behaviour and overnight motor memory consolidation in the dCBT group and changes in symptoms of depression and fatigue between the dCBT and control groups. Analysis of covariance models and correlations will be used to analyse data from the primary and secondary outcomes. ETHICS AND DISSEMINATION: The study has received approval from the National Research Ethics Service (22/EM/0080), Health Research Authority (HRA) and Health and Care Research Wales (HCRW), IRAS ID: 306 291. The results of this trial will be disseminated via presentations at scientific conferences, peer-reviewed publication, public engagement events, stakeholder organisations and other forms of media where appropriate.

Engaging Community Partners to Understand and Respond to Substance Use and Addiction Crisis Facing Families in Prince Albert, Saskatchewan.

Substance use is a persisting health care crisis that has led to residents' addiction to diverse substances in Prince Albert, Saskatchewan. This public health issue affects not only those with a substance use disorder but also those within their circle of family and friends. This paper aims to outline the community engagement processes that we undertook to identify community priorities for addressing the substance use and addiction issues facing them. We began the community engagement using a patient-oriented research process, which led to the development of a grant application. Following the awarding of this grant application by the Saskatchewan Health Research Foundation and Saskatchewan Centre for Patient-Oriented Research, we conducted interviews with family members affected by addiction in the city. The study provided us with significant insight into the impacts of substance use disorders on family members. The importance of collaboration among people with lived experience, health care providers, and community partners helped us to identify our research questions. Community members also actively participated in the data collection, analysis, and presentation of the findings where priorities for the interventions were identified. The conversations we had because of the community's engagement and participation in the research process enhanced our understanding of the realities of caring for people with substance use disorders and the importance of family involvement throughout the process. We also learned lessons regarding community engagement and participation in research on a stigmatizing and complex topic.

Evaluation of minimally invasive sampling methods for detecting Avipoxvirus: Hummingbirds as a case example.

Avian pox is a common avian virus that in its cutaneous form can cause characteristic lesions on a bird's dermal surfaces. Detection of avian pox in free-ranging birds historically relied on observations of visual lesions and/or histopathology, both which can underestimate avian pox prevalence. We compared traditional visual observation methods for avian pox with molecular methods that utilize minimally invasive samples (blood, toenail clipping, feathers, and dermal swabs) in an ecologically important group of birds, hummingbirds. Specifically, avian pox prevalence in several species of hummingbirds were examined across multiple locations using three different methods: (1) visual inspection of hummingbirds for pox-like lesions from a long-term banding data set, (2) qPCR assay of samples from hummingbird carcasses from wildlife rehabilitation centers, and (3) qPCR assay of samples from live-caught hummingbirds. A stark difference in prevalences among these three methods was identified, with an avian pox prevalence of 1.5% from banding data, 20.4% from hummingbird carcasses, and 32.5% from live-caught hummingbirds in California. This difference in detection rates underlines the necessity of a molecular method to survey for avian pox, and this study establishes one such method that could be applied to other wild bird species. Across all three methods, Anna's hummingbirds harbored significantly higher avian pox prevalence than other species examined, as did males compared with females and birds caught in Southern California compared with Northern California. After hatch-year hummingbirds also harbored higher avian pox prevalences than hatch-year hummingbirds in the California banding data set and the carcass data set. This is the first study to estimate the prevalence of avian pox in hummingbirds and address the ecology of this hummingbird-specific strain of avian pox virus, providing vital information to inform future studies on this charismatic and ecologically important group of birds.

Can a Portable Balance System Predict Fall Risk in Community-Dwelling Older Women?

PURPOSE: Increased fall risk has been linked to age, being female, and age-related changes in the postural control system. The purpose of this study was to determine if a portable balance system could predict fall risk by determining the relationship among the modified Clinical Test for Sensory Interaction on Balance (mCTSIB) scores, age, the Activities-specific Balance Confidence Scale (ABC) score, and the Berg Balance Scale (BBS) score in community-dwelling older women. Insight into these relationships may facilitate early intervention and decrease fall risk in older women. METHODS: This study was a non-experimental, prospective, cross-sectional, exploratory analysis to determine the relationship among the mCTSIB, age, ABC, and BBS. Women aged 65 years and over were selected from two independent living facilities using a sample of convenience (n=42). RESULTS: The mCTSIB firm surface, eyes open and the ABC predicted fall risk (BBS) scores, F(2, 36)=35.72, p<0.001, R2=0.67, but adding age did not significantly improve the model, b= -0.17, t(36)= -1.71, p=0.10. CONCLUSION: A portable balance system may be an effective screening tool to predict fall risk in community-dwelling older women and may be used by a variety of allied health professionals. Postural sway, and perceived balance, predicted fall risk scores (BBS). More specifically, data obtained from the mCTSIB firm surface, eyes open test condition when combined with ABC scores could lead to identification of increased fall risk, allowing clinicians to recommend early treatment intervention to prevent future falls.

Prospective validation of the RAPID clinical risk prediction score in adult patients with pleural infection: the PILOT study.

BACKGROUND: Over 30% of adult patients with pleural infection either die and/or require surgery. There is no robust means of predicting at baseline presentation which patients will suffer a poor clinical outcome. A validated risk prediction score would allow early identification of high-risk patients, potentially directing more aggressive treatment thereafter. OBJECTIVES: To prospectively assess a previously described risk score (the RAPID (Renal (urea), Age, fluid Purulence, Infection source, Dietary (albumin)) score) in adults with pleural infection. METHODS: Prospective observational cohort study that recruited patients undergoing treatment for pleural infection. RAPID score and risk category were calculated at baseline presentation. The primary outcome was mortality at 3 months; secondary outcomes were mortality at 12 months, length of hospital stay, need for thoracic surgery, failure of medical treatment and lung function at 3 months. RESULTS: Mortality data were available in 542 out of 546 patients recruited (99.3%). Overall mortality was 10% at 3 months (54 out of 542) and 19% at 12 months (102 out of 542). The RAPID risk category predicted mortality at 3 months. Low-risk mortality (RAPID score 0-2): five out of 222 (2.3%, 95% CI 0.9 to 5.7%); medium-risk mortality (RAPID score 3-4): 21 out of 228 (9.2%, 95% CI 6.0 to 13.7%); and high-risk mortality (RAPID score 5-7): 27 out of 92 (29.3%, 95% CI 21.0 to 39.2%). C-statistics for the scores at 3 months and 12 months were 0.78 (95% CI 0.71-0.83) and 0.77 (95% CI 0.72-0.82), respectively. CONCLUSIONS: The RAPID score stratifies adults with pleural infection according to increasing risk of mortality and should inform future research directed at improving outcomes in this patient population.

Does Hands-on Guarding Influence Performance on the Functional Gait Assessment?

BACKGROUND AND PURPOSE: An accurate fall risk assessment is an important component of fall prevention, though a fall could occur during testing. To minimize this risk, different guarding methods are used, though there is disagreement regarding the optimal method. The purpose of this study was to compare the effect of 2 guarding methods, contact guarding (CG) and standby guarding (SG), on performance during the Functional Gait Assessment (FGA). We hypothesized that (1) there would not be a significant difference in FGA scores when comparing CG with SG, and (2) participants would not perceive a difference between the 2 guarding methods. METHODS: Twenty-three community-dwelling older adults, mean age 73.6 (SD = 6.2) years, participated in this study. Each participant completed 2 trials of the FGA, one with CG and another with SG. Guarding for all trials was provided by the same experienced physical therapist (PT) for this within-subjects design. All trials were video recorded for review by 2 PT raters who were blinded to the purpose of the study. RESULTS AND DISCUSSION: Functional Gait Assessment scores for the 2 PT raters indicated high internal agreement for both CG and SG conditions (CG: intraclass correlation coefficient [ICC] = 0.949; SG: ICC = 0.935), and CG FGA scores did not significantly differ from SG FGA scores (t22 = 0.15, P = .882). Furthermore, none of the participants perceived a difference in guarding methods. CONCLUSIONS: The results of this study indicate that hands-on guarding does not significantly influence performance on the FGA when the guarding is provided by an experienced PT and the participant is a community-dwelling older adult.

Guide de pratique clinique fondé sur des données probantes pour l'examen périodique de la vue chez les enfants de 0 à 5 ans au Canada.

CONTEXTE: Étant donné que les maladies oculaires avant l'âge de 5 ans sont courantes, une certaine forme de dépistage des troubles de la vision devrait être effectuée chez les enfants avant qu'ils ne fréquentent l'école primaire. Cependant, l'absence de recommandations nationales cohérentes crée de la confusion chez les patients, les professionnels des soins oculovisuels et les gouvernements. MéTHODES: L'objectif de ce document est de fournir des recommandations quant aux types d'examens oculaires à pratiquer chez les enfants en bonne santé de 0 à 5 ans ainsi que sur le moment et la périodicité de tels examens. Une recension des écrits a produit 403 articles. Un comité d'experts multidisciplinaire (composé de deux optométristes, d'un ophtalmologiste effectuant des examens complets de la vue, d'un ophtalmologiste pratiquant en pédiatrie, d'un médecin de famille et d'un pédiatre) a établi de façon indépendante les articles jugés essentiels à la question clinique. Les articles se prêtant à un classement [n = 16] ont ensuite été soumis à une évaluation critique indépendante par un groupe externe, lequel a fourni un profil « GRADE ¼ des articles à utiliser et leur a attribué une cote. RECOMMANDATIONS: En plus du dépistage de routine effectué par les professionnels de première ligne, un examen complet de la vue mené par un professionnel possédant l'expertise nécessaire à la détection des facteurs de risque de l'amblyopie (comme un ophtalmologiste ou un optométriste) est requis durant la petite enfance. Les conclusions confirment l'importance de la détection précoce de l'amblyopie avant 36 mois et au plus tard 48 mois par le dépistage assorti d'au moins un examen complet de la vue avant l'âge de 5 ans. CONCLUSIONS: Le dépistage de la vue effectué chez les bébés et les enfants par les fournisseurs de soins de première ligne au cours des consultations de routine et des vaccinations périodiques est un élément essentiel de la détection des maladies oculaires. Toutefois, le potentiel de détection précoce est limité et un examen oculovisuel complet est également recommandé avant que l'enfant n'entre à l'école. Si l'amblyopie, le strabisme ou une autre pathologie oculaire est détecté ou soupçonné, et que le problème dépasse le champ de compétences du professionnel qui examine le patient, celui-ci peut être dirigé vers le spécialiste approprié, ce qui permet d'amorcer le traitement en temps opportun.

Evidence-based clinical practice guidelines for the periodic eye examination in children aged 0-5 years in Canada.

BACKGROUND: As eye disease before age 5 years is common, some form of vision screening should be performed on children before attending primary school. However, the lack of consistent national recommendations creates confusion for patients, eye care professionals, and governments alike. METHODS: The objective of this document is to provide guidance on the recommended timing, intervals, and types of ocular assessments for healthy children aged 0-5 years. A literature search yielded 403 articles. A multidisciplinary expert committee (comprising 2 optometrists, a comprehensive ophthalmologist, a pediatric ophthalmologist, a family physician, and a pediatrician) independently determined those articles deemed to be key to the clinical question. Articles that were gradable (n = 16) were then submitted for independent critical appraisal by an external review group, which provided a Grading of Recommendations Assessment, Development and Evaluation profile of the reviewed articles to use for assigning a grade of evidence. RECOMMENDATIONS: In addition to routine screening by a primary health care professional, a comprehensive eye examination by an individual with the expertise to detect risk factors for amblyopia-such as an ophthalmologist or optometrist-is required in early childhood. The findings support the importance of early detection of amblyopia before 36 months and no later than 48 months of age via screening with at least 1 comprehensive eye examination before age 5 years. CONCLUSIONS: Vision screening performed by primary health care providers during routine well-baby/child visits and scheduled vaccinations is an essential part of the detection of ocular disease. However, this early detection potential is limited, and a full oculovisual assessment is also recommended before the child entering the school system. If amblyopia, strabismus, or other eye pathology is detected or suspected that is beyond the scope of the eye care professional examining the patient, a referral to the appropriate specialist can be made, allowing treatment to be initiated in a timely fashion.

Value of Routine Eye Examinations in Asymptomatic Patients.

PURPOSE: To determine if routine eye examinations in asymptomatic patients result in spectacle prescription change, new critical diagnosis, or new management of existing conditions. We also investigate whether age and time between assessments (assessment interval) impact detection rates. METHODS: The Waterloo Eye Study (WatES) database was created from a retrospective file review of 6397 patients seen at the University of Waterloo Optometry Clinic. Significant changes since the previous assessment (significant change) were defined as a change in spectacle prescription, presence of a new critical diagnosis, or a new management. Significant change, assessment interval, and age were extracted from the database for all asymptomatic patients presenting for a routine eye examination. The frequency of patients with significant change and the median assessment interval were determined for different age groups. RESULTS: Of 2656 asymptomatic patients, 1078 (41%) patients had spectacle prescription changes, 434 (16%) patients had new critical diagnoses, 809 (31%) patients had new managements, and 1535 (58%) patients had at least one of these (significant change). Median assessment intervals were 2.9 and 2.8 years for age groups 40 to <65 years and 20 to <40 years, respectively, approximately 1.5 years for patients 7 to <20, and between 1 and 1.5 years for patients <7 or >64. Controlling for assessment interval and sex, increasing age was associated with having a significant change (OR = 1.03, 95% CI 1.029-1.037). Similarly, controlling for age and sex, increased assessment interval was associated with having a significant change (OR = 1.06, 95% CI 1.02-1.11). CONCLUSIONS: In asymptomatic patients, comprehensive routine optometric eye examinations detect a significant number of new eye conditions and/or result in management changes. The number detected increases with age and assessment interval.

Acoustic Hearing After Murine Cochlear Implantation: Effects of Trauma and Implant Type.

OBJECTIVES: To model the contribution of implant material and insertion trauma on loss of acoustic hearing after cochlear implantation in an appropriate animal model. METHODS: Sixty-five C57Bl/6J mice underwent unilateral implantation with implant grade materials: 2 implant grade silicones and a third uncoated platinum wire. A sham surgery group was included as a control. Serial auditory brainstem response (ABR) thresholds and distortion product otoacoustic emissions (DPOAEs) were used to discern effects on hearing over 22 weeks. Histologic measurements of damage to the organ of Corti and spiral ganglion were correlated with degree of hearing loss and material type. RESULTS: Organ of Corti damage correlated with rate of hearing loss soon after implantation (0-2 weeks) but not subsequently (2-22 weeks). Organ of Corti damage did not depend on implant type and was present even in sham surgery subjects when hearing was severely damaged. Spiral ganglia appeared unaffected. There was no evidence of an inflammatory or toxic effect of the materials beyond the site of implant insertion. CONCLUSIONS: Hearing loss and cochlear damage appear to be related to insertion trauma, with minimal effect on delayed hearing loss caused by different materials. In the C57Bl/6J mouse model, the sensory epithelium appears to be the location of damage after cochlear implantation.

Examination of the use of a dual-channel functional electrical stimulation system on gait, balance and balance confidence of an adult with spastic diplegic cerebral palsy.

The purpose of this case report is to determine the effects of a dual-channel functional electrical stimulation (FES) system on gait and balance of a 57-year-old male diagnosed with spastic diplegic cerebral palsy (CP). Outcome measures included the: Activities-specific Balance Confidence Scale (ABC); Dynamic Gait Index (DGI); Observational Gait Scale (OGS) and Tinetti Performance Oriented Mobility Assessment (POMA). Assessments were completed with and without use of FES during the initial examination and after two, four and six weeks of intervention with FES. ABC Scale scores improved from 32.8 to 48.1% during the 6-week intervention. Scores on the DGI improved from 6/24 to 9/24 without FES and from 9/24 to 14/24 with FES. OGS scores improved on both legs with and without FES. Tinetti POMA scores improved from 12/28 to 15/28 without FES and decreased from 16/28 to 15/28 with FES. The patient demonstrated improvement in both objective and subjective measures. The use of FES facilitated improved gait and balance; however, the patient was still at increased risk for falls after the 6-week intervention despite improved scores on the ABC Scale, DGI, OGS and Tinetti POMA.

The Effect of Age on Postoperative Morbidity in Women Undergoing Urogynecologic Surgery.

OBJECTIVES: The objectives of this study were to estimate the effect of older age on postoperative morbidity and to assess other factors associated with postoperative complications after urogynecologic surgery. METHODS: We conducted a retrospective cohort study of 508 women who underwent pelvic floor reconstructive surgery between March 2011 and June 2013. Our 2 cohorts were based on age--women younger than 65 years and women aged 65 years or older. Our primary outcome was clinically significant postoperative complications defined as Dindo-Clavien grade greater than or equal to 2. We compared the risk of postoperative morbidity between the cohorts and constructed a logistic regression analysis to adjust for potential confounders. RESULTS: Of the 508 patients, 300 (59.1%) were in the younger cohort and 208 (40.9%) were in the older cohort. For our primary outcome, we found that older women had a significantly higher rate of clinically significant postoperative complications (12.5% vs. 6.7%, P = 0.02). In a multivariate logistic regression model that included advanced prolapse, smoking status, Charlson Comorbidity Index, body mass index, and operative time, older age remained significantly associated with greater postoperative morbidity (odds ratio, 2.06; 95% confidence interval, 1.03-4.11). The length of surgery in hours was also associated with greater morbidity (odds ratio, 1.47; 95% confidence interval, 1.14-1.66). CONCLUSIONS: Women aged 65 years and older who underwent urogynecologic surgery had a higher risk of clinically significant postoperative complications based on the Dindo-Clavien Scale when compared with women younger than 65 years.

Short-term mesh exposure after robotic sacrocolpopexy with and without concomitant hysterectomy.

OBJECTIVES: The primary objective of this study was to compare the short-term rate of mesh exposure after a robotic sacrocolpopexy (RSCP) compared with those after RSCP with a concomitant hysterectomy. Secondary objectives included a comparison of mesh exposure from total hysterectomies (TH) versus supracervical hysterectomies (SCH) and determination of risk factors for mesh exposure. METHODS: This was a retrospective cohort study of women who underwent RSCP between January 2009 and December 2011 at one academic center. The primary outcome was mesh exposure at 6 weeks postoperation. Subjects were divided into two groups: those with concomitant hysterectomy and those with RSCP alone. The hysterectomy group was subdivided into TH versus SCH. Mesh exposures and mesh revision procedures were identified using International Classification of Diseases-9 and CPT codes, respectively, and confirmed by chart review. RESULTS: There were 230 eligible women who underwent RSCP during the study period and were followed up at a 6-week postoperative visit; 118 (51.7%) had RSCP only and 112 (48.7%) had a concomitant hysterectomy. Of those who underwent hysterectomy, 79 patients (70.5%) had TH and 33 (29.5%) had SCH. There were nine (3.9%) mesh exposures attributed to RSCP. The difference between the RSCP + hysterectomy group and the RSCP-only group was 2.7% versus 5.1% (P = 0.50). The 2.7% of mesh exposures in the hysterectomy group were associated with TH and none with SCH, but this difference was not significant (P = 0.55). CONCLUSIONS: Although mesh exposure with RSCP is low, serious morbidity can be associated with mesh use and appropriate preoperative counseling is critical.

Does government assistance improve utilization of eye care services by low-income individuals?

OBJECTIVE: To examine whether government-funded, low-income vision care programs improve use of eye care services by low-income individuals in Canada. DESIGN: Cross-sectional survey. PARTICIPANTS: 27,375 white respondents to the Canadian Community Health Survey (CCHS) Healthy Aging 2008/2009. METHODS: Government-funded, low-income vision care programs were reviewed. The amount of assistance provided was compared with professional fee schedules for general/routine eye examinations and market prices for eyeglasses. The utilization of eye care providers was derived from the CCHS. RESULTS: To receive low-income vision care assistance, individuals must be in receipt of social assistance. Criteria for receiving social assistance are stringent. The Canadian Financial Capability Survey revealed that 7.9% of Canadians aged 45 to 64 years and 5.5% aged ≥65 years received social assistance in 2009. The CCHS found in 2008/2009 that 12.5% of citizens aged 45 to 64 years and 13.2% of those aged ≥65 years had difficulty paying for basic expenses such as food. In 5 provinces, low-income vision care assistance fully covers a general/routine eye examination. In the remainder, the assistance provided is insufficient for a general/routine eye examination. The assistance for eyeglasses is inadequate in 5 provinces, requiring out-of-pocket copayments. Among middle-aged whites who self-reported not having glaucoma, cataracts, diabetes, or vision problems not corrected by lenses, utilization of eye care providers was 28.1% among those with financial difficulty versus 41.9% among those without (p < 0.05), giving a prevalence ratio 0.68 (95% CI 0.57-0.80) adjusted for age, sex and education. CONCLUSIONS: Despite government assistance, low-income individuals use vision care services less often than wealthy individuals.

Randomized trial of a web-based tool for prolapse: impact on patient understanding and provider counseling.

INTRODUCTION AND HYPOTHESIS: Effective patient/provider communication is important to ensure patient understanding, safety, and satisfaction. Our hypothesis was that interactive patient/provider counseling using a web-based tool (iPad application) would have a greater impact on patient satisfaction with understanding prolapse symptoms compared with standard counseling (SC). METHODS: Women with complaints of seeing/sensing a vaginal bulge were enrolled in this randomized controlled trial. Participants completed pre- and postvisit Likert scale questionnaires on satisfaction with prolapse knowledge and related anxiety. After new patient histories and physical examinations, study participants were randomized to SC or SC with iPad. Ninety participants were required to detect a 30% difference in satisfaction with prolapse knowledge between the two groups. RESULTS: Ninety women were randomized to SC (n = 44) or SC with iPad (n = 46). At baseline, 47% of women were satisfied with their understanding of bulge symptoms (50% SC vs. 43.5% SC with iPad, p = 0.5). After counseling, 97% of women reported increased satisfaction with understanding of bulge symptoms (p < 0.0001), with no difference between groups [42/44 (95.5%) SC vs. 45/46 (97.8%) SC with iPad, p = 0.5]. Baseline anxiety was high: 70% (65.9% SC vs. 73.9% SC with iPad, p = 0.4). After counseling, anxiety decreased to 30% (p < 0.0001), with improvement in both groups (31.8% SC vs. 28.3% SC with iPad™, p = 0.7). Counseling times were similar between groups (9.5 min., SC vs. 8.9 min., SC with iPad, p = 0.4). CONCLUSIONS: Interactive counseling was associated with increased patient satisfaction with understanding bulge symptoms and decreased anxiety whether a web-based tool was used or not.
