RESUMO
BACKGROUND: The effect of computer-aided polyp detection (CADe) on adenoma detection rate (ADR) among endoscopists-in-training remains unknown. METHODS: We performed a single-blind, parallel-group, randomized controlled trial in Hong Kong between April 2021 and July 2022 (NCT04838951). Eligible subjects undergoing screening/surveillance/diagnostic colonoscopies were randomized 1:1 to receive colonoscopies with CADe (ENDO-AID[OIP-1]) or not (control) during withdrawal. Procedures were performed by endoscopists-in-training with <500 procedures and <3 years' experience. Randomization was stratified by patient age, sex, and endoscopist experience (beginner vs intermediate level, <200 vs 200-500 procedures). Image enhancement and distal attachment devices were disallowed. Subjects with incomplete colonoscopies or inadequate bowel preparation were excluded. Treatment allocation was blinded to outcome assessors. The primary outcome was ADR. Secondary outcomes were ADR for different adenoma sizes and locations, mean number of adenomas, and non-neoplastic resection rate. RESULTS: A total of 386 and 380 subjects were randomized to CADe and control groups, respectively. The overall ADR was significantly higher in the CADe group than in the control group (57.5% vs 44.5%; adjusted relative risk, 1.41; 95% CI, 1.17-1.72; P < .001). The ADRs for <5 mm (40.4% vs 25.0%) and 5- to 10-mm adenomas (36.8% vs 29.2%) were higher in the CADe group. The ADRs were higher in the CADe group in both the right colon (42.0% vs 30.8%) and left colon (34.5% vs 27.6%), but there was no significant difference in advanced ADR. The ADRs were higher in the CADe group among beginner (60.0% vs 41.9%) and intermediate-level (56.5% vs 45.5%) endoscopists. Mean number of adenomas (1.48 vs 0.86) and non-neoplastic resection rate (52.1% vs 35.0%) were higher in the CADe group. CONCLUSIONS: Among endoscopists-in-training, the use of CADe during colonoscopies was associated with increased overall ADR. (ClinicalTrials.gov, Number: NCT04838951).

OBJECTIVE: To evaluate the effects of denosumab on erosion healing at 2-4 metacarpophalangeal (MCP) head as determined by high-resolution peripheral quantitative CT (HR-pQCT) in patients with rheumatoid arthritis (RA) with stable disease. METHODS: This was a randomised, placebo-controlled, double-blind study. Patients with RA with disease activity score 28 joints (DAS28) ≤5.1 were randomised (1:1) to subcutaneous denosumab 60 mg or placebo once every 6 months for 24 months. The primary outcome was erosion healing at MCP 2-4 on HR-pQCT at 12 months. The effects of denosumab on erosion and joint space parameters on HR-pQCT and radiographs, disease activity and health assessment questionnaire-disability index (HAQ-DI) were also examined. RESULTS: At 24 months, HR-pQCT images were analysed in 98 patients. One-third of the patients achieved sustained low disease activity throughout the study. At 12 months, changes in erosion parameters on HR-pQCT were similar between the two groups. At 24 months, new erosions (19% vs 9%, p=0.009) and erosion progression (18% vs 8%, p=0.019) were more common in the placebo group than the denosumab group. Erosion healing was seen in a significantly higher proportion of patients in the denosumab group (20% vs 6%, p=0.045) at 24 months. No significant changes in joint space parameters on HR-pQCT, van der Heijde-Sharp erosion score, DAS28 and HAQ-DI were observed in the two groups at 12 and 24 months. CONCLUSION: Although no differences in erosion parameters were observed at 12 months, denosumab was more efficacious than placebo in erosion repair on HR-pQCT after 24 months. TRIAL REGISTRATION NUMBER: NCT03239080.

BACKGROUND: Few resources are available to support caregivers of patients who have survived critical illness; consequently, the caregivers' own health may suffer. We studied caregiver and patient characteristics to determine which characteristics were associated with caregivers' health outcomes during the first year after patient discharge from an intensive care unit (ICU). METHODS: We prospectively enrolled 280 caregivers of patients who had received 7 or more days of mechanical ventilation in an ICU. Using hospital data and self-administered questionnaires, we collected information on caregiver and patient characteristics, including caregiver depressive symptoms, psychological well-being, health-related quality of life, sense of control over life, and effect of providing care on other activities. Assessments occurred 7 days and 3, 6, and 12 months after ICU discharge. RESULTS: The caregivers' mean age was 53 years, 70% were women, and 61% were caring for a spouse. A large percentage of caregivers (67% initially and 43% at 1 year) reported high levels of depressive symptoms. Depressive symptoms decreased at least partially with time in 84% of the caregivers but did not in 16%. Variables that were significantly associated with worse mental health outcomes in caregivers were younger age, greater effect of patient care on other activities, less social support, less sense of control over life, and less personal growth. No patient variables were consistently associated with caregiver outcomes over time. CONCLUSIONS: In this study, most caregivers of critically ill patients reported high levels of depressive symptoms, which commonly persisted up to 1 year and did not decrease in some caregivers.

RATIONALE: Disability risk groups and 1-year outcome after greater than or equal to 7 days of mechanical ventilation (MV) in medical/surgical intensive care unit (ICU) patients are unknown and may inform education, prognostication, rehabilitation, and study design. OBJECTIVES: To stratify patients for post-ICU disability and recovery to 1 year after critical illness. METHODS: We evaluated a multicenter cohort of 391 medical/surgical ICU patients who received greater than or equal to 1 week of MV at 7 days and 3, 6, and 12 months after ICU discharge. Disability risk groups were identified using recursive partitioning modeling. MEASUREMENTS AND MAIN RESULTS: The 7-day post-ICU Functional Independence Measure (FIM) determined the recovery trajectory to 1-year after ICU discharge and was an independent risk factor for 1-year mortality. The 7-day post-ICU FIM was predicted by age and ICU length of stay. By 2 weeks of MV, ICU patients could be stratified into four disability groups characterized by increasing risk for post ICU disability, ICU and post-ICU healthcare use, and disposition. Patients less than 42 years with ICU length of stay less than 2 weeks had the best function and fewest deaths at 1 year compared with patients greater than 66 years with ICU length of stay greater than 2 weeks who sustained the worst disability and 40% 1-year mortality. Depressive symptoms (17%) and post-traumatic stress disorder (18%) persisted at 1 year. CONCLUSIONS: ICU survivors of greater than or equal to 1 week of MV may be stratified into four disability groups based on age and ICU length of stay. These groups determine 1-year recovery and healthcare use and are independent of admitting diagnosis and illness severity. Clinical trial registered with www.clinicaltrials.gov (NCT 00896220).
RESUMO
Introduction: Acute rehabilitation in critically ill patients can improve post-intensive care unit (post-ICU) physical function. In-bed cycling early in a patient's ICU stay is a promising intervention. The objective of this study was to determine the feasibility of recruitment, intervention delivery and retention in a multi centre randomised clinical trial (RCT) of early in-bed cycling with mechanically ventilated (MV) patients. Methods: We conducted a pilot RCT conducted in seven Canadian medical-surgical ICUs. We enrolled adults who could ambulate independently before ICU admission, within the first 4 days of invasive MV and first 7 days of ICU admission. Following informed consent, patients underwent concealed randomisation to either 30 min/day of in-bed cycling and routine physiotherapy (Cycling) or routine physiotherapy alone (Routine) for 5 days/week, until ICU discharge. Our feasibility outcome targets included: accrual of 1-2 patients/month/site; >80% cycling protocol delivery; >80% outcomes measured and >80% blinded outcome measures at hospital discharge. We report ascertainment rates for our primary outcome for the main trial (Physical Function ICU Test-scored (PFIT-s) at hospital discharge). Results: Between 3/2015 and 6/2016, we randomised 66 patients (36 Cycling, 30 Routine). Our consent rate was 84.6 % (66/78). Patient accrual was (mean (SD)) 1.1 (0.3) patients/month/site. Cycling occurred in 79.3% (146/184) of eligible sessions, with a median (IQR) session duration of 30.5 (30.0, 30.7) min. We recorded 43 (97.7%) PFIT-s scores at hospital discharge and 37 (86.0%) of these assessments were blinded. Discussion: Our pilot RCT suggests that a future multicentre RCT of early in-bed cycling for MV patients in the ICU is feasible. Trial registration number: NCT02377830.

BACKGROUND: Clinical trials management can be studied using project management theory. The CYCLE pilot randomized controlled trial (RCT) was conducted to determine the feasibility of a future rehabilitation trial of early in-bed cycling in the intensive care unit (ICU). In-bed cycling is a novel intervention, not typically available in ICUs. Implementation of this intervention requires personnel with specialized clinical expertise caring for critically ill patients and use of the in-bed cycle. Our objective was to describe the implementation and conduct of our pilot RCT using a project management approach. METHODS: We retrospectively reviewed activities, timelines, and personnel involved in the trial. We organized activities into four project management phases: initiation, planning, execution, and monitoring and controlling. Data sources included Methods Centre documents used for trial coordination and conduct, and the trial data set. We report descriptive statistics as counts and proportions and also medians and quartiles, and we summarize the lessons learned. RESULTS: Seven ICUs in Canada participated in the trial. Time from research ethics board and contracts submission to first enrolment was a median (first quartile, third quartile) of 185 (146, 209) and 162 (114, 181) days, respectively. We trained 128 personnel on the CYCLE pilot RCT protocol, and 80 (63%) completed trial-related activities. Four sites required additional training after start-up due to staff turnover and leaves of absence. Over 15 months, we screened 864 patients: 256 were eligible and 66 were enrolled. Despite an 85% consent rate, 74% (190/256) of eligible patients were not randomized, largely (80% [152/190]) due to physiotherapist availability. Thirteen percent of recruitment weeks were lost due to physiotherapist staffing shortages. We highlight five key lessons learned: (1) prepare and anticipate site needs; (2) communicate regularly; (3) proactively analyse and act on process measure data; (4) develop contingency plans; (5) express appreciation to participating sites. CONCLUSIONS: Our analysis highlights the scope of relevant activities, rigorous training and monitoring, number and types of required personnel, and time required to conduct a multicentre ICU rehabilitation intervention trial. Our lessons learned can help others interested in implementing complex intervention trials, such as rehabilitation. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02377830 .

RESUMO
RATIONALE: There are limited data on physiotherapy during extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome (ARDS). OBJECTIVES: We sought to characterize physiotherapy delivered to patients with ARDS supported with ECMO, as well as to evaluate the association of this therapeutic modality with mortality. METHODS: We conducted a retrospective cohort study of all adult patients with ARDS supported with ECMO at our institution between 2010 and 2015. The highest level of daily activity while on ECMO was coded using the ICU Mobility Scale. Through multivariable logistic regression, we evaluated the association between intensive care unit (ICU) physiotherapy and ICU mortality. In an exploratory univariate analysis, we also evaluated factors associated with a higher intensity of ICU rehabilitation while on ECMO. MEASUREMENTS AND MAIN RESULTS: Of 107 patients who underwent ECMO, 61 (57%) had ARDS requiring venovenous ECMO. The ICU physiotherapy team was consulted for 82% (n = 50) of patients. Thirty-nine percent (n = 18) of these patients achieved an activity level of 2 or higher (active exercises in bed), and 17% (n = 8) achieved an activity level 4 or higher (actively sitting over the side of the bed). In an exploratory analysis, consultation with the ICU physiotherapy team was associated with decreased ICU mortality (odds ratio, 0.19; 95% confidence interval, 0.04-0.98). In univariate analysis, severity-of-illness factors differentiated higher-intensity and lower-intensity physiotherapy. CONCLUSIONS: Physiotherapy during ECMO is feasible and safe when performed by an experienced team and executed in stages. Although our study suggests an association with improved ICU mortality, future research is needed to identify potential barriers, optimal timing, dosage, and safety profile.

Sulfonylureas, metformin, thiazolidinediones, and non-sulfonylurea secretagogues differ little in their ability to decrease glycosylated hemoglobin (Hb A1c) levels when used as initial monotherapy for diabetes mellitus type 2 (strength of recommendation [SOR]: A, based on systematic reviews); alpha-glucosidase inhibitors may also be as effective (SOR: B, based on systematic reviews with inconsistent results). Metformin is generally indicated in obese patients because it improves all-cause mortality and diabetes related outcomes (SOR: B, based on a single high-quality randomized controlled trial [RCT]). Insulin is generally not recommended as an initial agent (SOR: C, expert opinion).

Combination therapy using insulin plus metformin (Glucophage), a sulfonylurea, or both produces glycemic control comparable with using insulin alone, but there is less weight gain when metformin is used (strength of recommendation [SOR]: B, based on systematic review of randomized controlled trials [RCTs] with some heterogeneity). Combination therapy using insulin and pioglitazone (Actos) reduces glycosylated hemoglobin (Hb A1c) more than either insulin alone or adding pioglitazone to a sulfonylurea, but results in more weight gain (SOR: A, based on RCT). Using insulin glargine (Lantus) in combination therapy produces fewer nocturnal hypoglycemic events than using neutral protamine Hagedorn (NPH) insulin, while producing equivalent Hb A1c reduction (SOR: B, based on RCT). When the HbA1c is high (above 9.0% to 9.5%) on 1 or 2 oral agents, beginning combination therapy is more effective than adding another oral agent (SOR: B, based on subpopulation analysis in RCTs).

Split tablets of lisinopril are as effective as whole tablets of the same dose for hypertension (strength of recommendation [SOR]: B, based on small randomized crossover study). Similarly, split tablets of atorvastatin, lovastatin, and simvastatin are no less effective for lowering cholesterol (SOR: B, based on retrospective cohort studies). Extended-release, enteric-coated, or tablets that cannot be split accurately are not appropriate for splitting (SOR: C, based on observational studies); the accuracy of splitting also depends on device used and user skill (SOR: C, based on observational study).

Cyclo-oxygenase-2 (COX-2) selective nonsteroidal anti-inflammatory drugs (NSAIDs) are as effective as acetaminophen and nonselective NSAIDs in treating of osteoarthritis, and are equally effective in reducing pain and inflammation and improving of joint function for patients with rheumatoid arthritis, when compared with nonselective NSAIDs. The COX-2 selective NSAIDs also have a better gastrointestinal safety profile in short-term (6-12 month) treatment (strength of recommendation [SOR]: A, based on meta-analysis of randomized controlled trials with patient-oriented outcomes). However, with recent growing concern of the cardiovascular safety of COX-2 selective NSAIDs, it is imperative to select appropriate patients by considering benefit vs risks, which include serious gastrointestinal bleeding, history of intolerance to nonselective NSAID, cardiovascular disease or associated risks, renal disease, patient's preference, and cost.

Physical rehabilitation of lung transplant candidates and recipients plays an important in optimizing physical function prior to transplant and facilitating recovery of function post-transplant. As medical and surgical interventions in lung transplantation have evolved over time, there has been a demographic shift of individuals undergoing lung transplantation including older individuals, those with multiple co-morbidites, and candidates with respiratory failure requiring bridging to transplantation. These changes have an impact on the rehabilitation needs of lung transplant candidates and recipients. This review provides a practical approach to rehabilitation based on research and clinical practice at our transplant centre. It focuses on functional assessment and exercise prescription during an uncomplicated and complicated clinical course in the pre-transplant, early and late post-transplant periods. The target audience includes clinicians involved in pre- and post-transplant patient care and rehabilitation researchers.
RESUMO
BACKGROUND: The promotion of early mobilization following critical illness is tempered by national reports of patient and institutional barriers to this approach. We carried out a survey to assess current knowledge, perceptions and practices of Canadian physicians and physiotherapists with respect to acquired weakness and early mobilization in adults in the intensive care unit (ICU). METHODS: We conducted a cross-sectional, self-administered postal survey among critical care physicians and physiotherapists in all 46 academic ICUs in Canada in 2011-2012. To identify all physicians and physiotherapists working in the ICUs, we contacted division heads and senior physiotherapists by telephone or email. We designed, tested and administered a questionnaire with the following domains: knowledge of ICU-acquired weakness and early mobilization; personal views of, perceived barriers to and adequacy of technical skills for early mobilization; assessments for initiation of early mobilization and permissible activity levels by patient physiologic characteristics, diagnoses and therapies; staffing issues; and sedation practices. RESULTS: The overall response rate was 71.3% (311/436); it was 64.2% (194/302) among physicians and 87.3% (117/134) among physiotherapists. A total of 214 respondents (68.8%) underestimated the incidence of ICU-acquired weakness in the general medical-surgical ICU population, and 186 (59.8%) stated they had insufficient knowledge or skills to mobilize patients receiving mechanical ventilation. Excessive sedation, medical instability, limited staffing, safety concerns, insufficient guidelines and insufficient equipment were common perceived barriers to early mobilization. INTERPRETATION: Physicians and physiotherapists in the ICU underestimated the incidence of ICU-acquired weakness and felt inadequately trained to mobilize patients receiving mechanical ventilation. We identified multiple modifiable barriers to early mobilization at the institutional, health care provider and patient levels that need to be addressed when designing mobilization programs for critically ill adults.

BACKGROUND: Abundant, indirect epidemiological evidence indicates that influenza contributes to all-cause mortality and cardiovascular hospitalisations with studies showing increases in acute myocardial infarction (AMI) and death during the influenza season. OBJECTIVE: To investigate whether influenza is a significant and unrecognised underlying precipitant of AMI. DESIGN: Case-control study. SETTING: Tertiary referral hospital in Sydney, Australia, during 2008 to 2010. PATIENTS: Cases were inpatients with AMI and controls were outpatients without AMI at a hospital in Sydney, Australia. MAIN OUTCOME MEASURES: Primary outcome was laboratory evidence of influenza. Secondary outcome was baseline self-reported acute respiratory tract infection. RESULTS: Of 559 participants, 34/275 (12.4%) cases and 19/284 (6.7%) controls had influenza (OR 1.97, 95% CI 1.09 to 3.54); half were vaccinated. None were recognised as having influenza during their clinical encounter. After adjustment, influenza infection was no longer a significant predictor of recent AMI. However, influenza vaccination was significantly protective (OR 0.55, 95% CI 0.35 to 0.85), with a vaccine effectiveness of 45% (95% CI 15% to 65%). CONCLUSIONS: Recent influenza infection was an unrecognised comorbidity in almost 10% of hospital patients. Influenza did not predict AMI, but vaccination was significantly protective but underused. The potential population health impact of influenza vaccination, particularly in the age group 50-64 years, who are at risk for AMI but not targeted for vaccination, should be further explored. Our data should inform vaccination policy and cardiologists should be aware of missed opportunities to vaccinate individuals with ischaemic heart disease against influenza.

BACKGROUND AND OBJECTIVES: In July 2010, the Accreditation Council for Graduate Medical Education (ACGME) published its proposed duty-hour regulations. We conducted a national online survey to assess current family medicine residents' perceptions of the proposed changes. METHODS: A 27-question survey was used to assess four ACGME proposal domains: resident supervision, 80-duty-hour week, maximum duty-period length, and maximum frequency of in-hospital duty. Additionally, we surveyed opinions on reasonable weekly work hours, under-reporting practice, and residents' activities during hours off, residents' perceptions of their program's ability to comply with future duty-hour regulations, and their overall satisfactions. Members of the Association of Family Medicine Residency Directors (AFMRD) were invited to send the survey Web link to their residents. RESULTS: Out of 720 respondents, 30% supported revision of current duty-hour work rules; 58% disagreed with limiting interns' working hours to 16 hours per day; 48% perceived revision of resident supervision favorably; 26% expressed concern about continuing the current 80-duty-hour week rule; 75% supported limiting night duty to six consecutive nights; 83% agreed that reasonable resident weekly work hours should be 60-80 hours; and 18% admitted under-reporting of duty hours. Residents' hours off activities varied. Only 57% believed that their program will be able to implement the new changes effectively. Overall satisfaction with the future duty-hour rules were mixed: very satisfied (7%), satisfied (24%), somewhat satisfied (27%), unsatisfied (23%), and very unsatisfied (18%). CONCLUSIONS: Support for the proposed ACGME duty-hour regulations was mixed among current family medicine residents. Respondents and residency program directors shared similar concerns about some of the recommended changes.
