Internet-delivered cognitive behaviour therapy for chronic health conditions: self-guided versus team-guided.

There is growing interest in offering Internet-delivered cognitive behaviour therapy (ICBT) to individuals with chronic health conditions, with this process often being guided by a single clinician. Due to lack of full time personnel, it is sometimes necessary to have multiple clinicians offer guidance or for no guidance to be offered. In this randomized trial, we compared team-guided ICBT (n = 90) to self-guided ICBT (n = 88). Participants completed measures at pre-, post-, and 3-months post-ICBT. Both groups showed similar rates of treatment completion and large improvements on depression and anxiety at post-treatment and follow-up. Unexpectedly, more participants in the self-guided versus team-guided condition showed clinically significant improvement on depression at post-treatment (76.5% vs 49.2%) and follow-up (70% vs 45.6%). Thus, team-guided ICBT may not provide significant benefits compared to self-guided ICBT. However, it may be an alternative approach to consider among a population of high risk individuals that wants or requires closer monitoring of symptoms.Trail registration TRN: NCT03500237; Date: April 18, 2018.

Juvenile Gouldian finches (Erythrura gouldiae) form sibling subgroups during social integration.

The formation of social relationships in complex groups is critical in shaping patterns of social organization and behavioral development. In many birds, young individuals remain dependent on their parents for extended periods but must abruptly transition to navigating interactions in the wider group after independence. While lack of social relationships during this period is detrimental in the development of later social skills, little is known about the social relationships juveniles form after independence in many bird species. In this study, we describe patterns of social interactions in juvenile Gouldian finches (Erythrura gouldiae) during transitions from family groups into flocks of unfamiliar individuals. Twenty juveniles from four families were introduced into two flocks. After introductions, juveniles showed a gradient of approach rates with most approaches directed toward siblings, followed by juvenile peers, adult females, and lastly adult males. Significant preferences for siblings resulted in the emergence of sibling subgroups within the larger social network. This intentional self-assortment of siblings suggests that sibling subgroups are an important bridge linking social connections within the family and the wider group. Such findings suggests that sibling relationships have a critical role in the socialization after independence, as well as structuring the social organization of Gouldian finch flocks.

Adipose-only sentinel lymph nodes: a finding during the adaptation of a sentinel lymph node mapping algorithm with indocyanine green in women with endometrial cancer.

OBJECTIVE: To identify factors that affect successful adaptation of sentinel lymph node mapping and those that lead to unintended adipose-only sentinel lymph node identification. METHODS: Surgical and pathological data were prospectively collected on patients with endometrial cancer who underwent sentinel lymph node mapping with indocyanine green with or without pelvic and/or para-aortic lymph node dissection between November 2013 and April 2017. All mapping cases were performed with the robotic system. Adipose-only specimens were defined as a sentinel lymph node without a pathologically identified lymph node after ultrastaging. RESULTS: A total of 202 patients were included: 83% had endometrioid pathology, 12% serous, 3% carcinosarcoma, and 2% clear cell, with mixed pathology noted in 2%. The bilateral sentinel lymph node detection rate was 66%, and the rate of mapping at least a unilateral sentinel lymph node was 86%. Neither the bilateral nor the unilateral sentinel lymph node mapping rate changed with increased surgeon experience. The rate of adipose-only sentinel lymph node identification was more frequent when comparing the first 10 cases (37%), cases 11 - 30 (28%), and > 30 cases (9%) (P = 0.006). Body mass index > 30 kg/m2, uterine fibroids, The International Federation of Gynecology and Obstetrics (FIGO) grade, and histology were not found to have a statistically significant impact on either sentinel lymph node identification or adipose-only sentinel lymph node identification. Adipose-only sentinel lymph nodes were more likely with increased time from cervical injection to identification of the sentinel lymph node in the right hemipelvis. The median range was 28 min (14-73) for true sentinel lymph node identification vs 33 min (23-74) for adipose-only sentinel lymph node identification (P = 0.02). CONCLUSION: Patient and surgeon factors did not impact the identification of sentinel lymph nodes over time. Adipose-only sentinel lymph nodes were more frequently identified in the initial cases and represent a potential complication to adapting sentinel lymph node biopsy without lymphadenectomy. The increase in adipose-only sentinel lymph node identification that was associated with time from cervical injection may represent delayed or disrupted uptake of indocyanine green.

Patient Perspectives on Strengths and Challenges of Therapist-Assisted Internet-Delivered Cognitive Behaviour Therapy: Using the Patient Voice to Improve Care.

Therapist-assisted internet-delivered cognitive behaviour therapy (T-ICBT) involves patients reading online treatment materials, completing relevant exercises, and receiving therapist support. This study aimed to understand the preferences and recommendations of 225 patients enrolled in a T-ICBT course for depression and anxiety via an online therapy unit in collaboration with community mental health clinics dispersed across one Canadian province. An open-ended survey asked participants their opinions of the course and responses were analyzed using a content analysis approach. Patient comments addressed many strengths of the course (64%), with some opportunities for improvement (36%). Most-appreciated features included ability to download content for future use, reading other patients' experiences, and content of lessons. Patients made suggestions for improving the breadth of patient stories, timeline of the course, and matching availability of the therapist to patient need. Patient feedback regarding preferences provides valuable information for improving the patient-centered nature of T-ICBT.

Academic Background of Irish Orthopaedic Trainees

Introduction Academic achievement may be used to distinguish between trainees in competition for training or consultant posts. This study aimed to quantify the academic achievement among orthopaedic trainees in Ireland. Methods A web-based questionnaire was distributed to all trainees on the Irish Trauma and Orthopaedics specialist training programme. Questions included current year of training and attainment of higher degrees, publications, grants and prizes. Results Thirty-eight of 51 trainees completed the questionnaire (74%). All had commenced or completed a higher degree, more frequently a taught programme among ST3 and ST4 trainees and research based among the more senior years. Thirty-five (69%) had at least one peer-reviewed publication at the time of appointment. All continued some research activity. A majority aspire to a predominantly clinical career. Discussion Levels of academic achievement remain high among Irish orthopaedic trainees. Although junior trainees have fewer publications at appointment, all continue research on the training programme.

Implementation of internet-delivered cognitive behavior therapy within community mental health clinics: a process evaluation using the consolidated framework for implementation research.

BACKGROUND: Depression and anxiety are prevalent and under treated conditions that create enormous burden for the patient and the health system. Internet-delivered cognitive behavior therapy (ICBT) improves patient access to treatment by providing therapeutic information via the Internet, presented in sequential lessons, accompanied by brief weekly therapist support. While there is growing research supporting ICBT, use of ICBT within community mental health clinics is limited. In a recent trial, an external unit specializing in ICBT facilitated use of ICBT in community mental health clinics in one Canadian province (ISRCTN42729166; registered November 5, 2013). Patient outcomes were very promising and uptake was encouraging. This paper reports on a parallel process evaluation designed to understand facilitators and barriers impacting the uptake and implementation of ICBT. METHODS: Therapists (n = 22) and managers (n = 11) from seven community mental health clinics dispersed across one Canadian province who were involved in implementing ICBT over ~2 years completed an online survey (including open and closed-ended questions) about ICBT experiences. The questions were based on the Consolidated Framework for Implementation Research (CFIR), which outlines diverse constructs that have the potential to impact program implementation. RESULTS: Analyses suggested ICBT implementation was perceived to be most prominently facilitated by intervention characteristics (namely the relative advantages of ICBT compared to face-to-face therapy, the quality of the ICBT program that was delivered, and evidence supporting ICBT) and implementation processes (namely the use of an external facilitation unit that aided with engaging patients, therapists, and managers and ICBT implementation). The inner setting was identified as the most significant barrier to implementation as a result of limited resources for ICBT combined with greater priority given to face-to-face care. CONCLUSIONS: The results contribute to understanding facilitators and barriers to using ICBT within community mental health clinics and serve to identify recommendations for improving uptake and implementation of ICBT in clinic settings.

MicroRNAs: exploring new horizons in osteoarthritis.

INTRODUCTION: Osteoarthritis (OA) is a common disease worldwide leading to significant morbidity. The underlying disease process is multifactorial however there is increasing focus on molecular mechanisms. MicroRNAs are small non-coding segments of RNA that have important regulatory functions at a cellular level. These molecules are readily detectable in human tissues and circulation. They are increasingly recognised as having a major role in many disease processes - including malignancy and inflammatory processes. OBJECTIVE: This review paper aims to provide a comprehensive update on the evidence for miRNA roles in OA. DESIGN: A comprehensive literature search was performed using key medical subject headings (MeSH) terms 'microRNA' and 'osteoarthritis'. RESULTS: Several miRNAs have been identified as having aberrant expression levels in OA. Some of these include miR-9, miR-27, miR-34a, miR-140, miR-146a, miR-558 and miR-602. Many of the dysregulated miRNAs have been shown to regulate expression of inflammatory pathways such as interleukin-mediated or matrix metalloproteinase-13 (MMP-13)-mediated degradation of the articular cartilage extracellular matrix (ECM). MiRNAs may also play a role in pain pathways and hence expression of clinical symptoms. CONCLUSIONS: Recent evidence has shown that miRNAs in the circulation may reflect underlying disease states and hence serve as potential markers for disease activity. These findings may represent possible future therapeutic applications in the management of OA.

Refining the continuum of CFTR-associated disorders in the era of newborn screening.

Clinical heterogeneity in cystic fibrosis (CF) often causes diagnostic uncertainty in infants without symptoms and in older patients with milder phenotypes. We performed a cross-sectional evaluation of a comprehensive set of clinical and laboratory descriptors in a physician-defined cohort (N = 376; Children's Hospital of Wisconsin and the American Family Children's Hospital CF centers in Milwaukee and Madison, WI, USA) to determine the robustness of categorizing CF (N = 300), cystic fibrosis transmembrane conductance regulator (CFTR)-related disorder (N = 19), and CFTR-related (CRMS) metabolic syndrome (N = 57) according to current consensus guidelines. Outcome measures included patient demographics, clinical measures, sweat chloride levels, CFTR genotype, age at diagnosis, airway microbiology, pancreatic function, infection, and nutritional status. The CF cohort had a significantly higher median sweat chloride level (105 mmol/l) than CFTR-related disorder patients (43 mmol/l) and CFTR-related metabolic syndrome patients (35 mmol/l; p ≤ 0.001). Patient groups significantly differed in pancreatic sufficiency, immunoreactive trypsinogen levels, sweat chloride values, genotype, and positive Pseudomonas aeruginosa cultures (p ≤ 0.001). An automated classification algorithm using recursive partitioning demonstrated concordance between physician diagnoses and consensus guidelines. Our analysis suggests that integrating clinical information with sweat chloride levels, CFTR genotype, and pancreatic sufficiency provides a context for continued longitudinal monitoring of patients for personalized and effective treatment.

Expectations of General Practitioners for Patients Undergoing Elective Total Knee Arthroplasty.

Most patients undergoing total knee arthroplasty (TKA) in Ireland are referred to orthopaedic services by their general practitioners (GPs). We aimed to evaluate Irish GPs' expectations for their patients' perioperative experience and post-operative return to function. A questionnaire was mailed to 350 GPs in all provinces. This included questions relating to GPs' expectations for their patients and their knowledge and sources of information on TKA. 111 completed questionnaires were returned (response rate 31.7%). Overall expectations for functional and psychological outcomes were high, especially regarding pain relief (108 (97.3%)) expected relief from most or all pre-operative pain), mobility (108 (97.3%)) expected patients to walk medium or long distances) and psychological wellbeing (95 (85.5%) considered this somewhat or very important). Only 22 (20.2%) reported receiving any relevant information or training within the previous year. Overall expectations for functional outcomes were high, however greater communication between surgeons and GPs may improve GP information,

Heparan sulfate-protein binding specificity.

Heparan sulfate (HS) represents a large class of linear polysaccharides that are required for the function of all mammalian physiological systems. HS is characterized by a repeating disaccharide backbone that is subject to a wide range of modifications, making this class of macromolecules arguably the most information dense in all of biology. The majority of HS functions are associated with the ability to bind and regulate a wide range of proteins. Indeed, recent years have seen an explosion in the discovery of new activities for HS where it is now recognized that this class of glycans functions as co-receptors for growth factors and cytokines, modulates cellular uptake of lipoproteins, regulates protease activity, is critical to amyloid plaque formation, is used by opportunistic pathogens to enter cells, and may even participate in epigenetic regulation. This review will discuss the current state of understanding regarding the specificity of HS-protein binding and will describe the concept that protein binding to HS depends on the overall organization of domains within HS rather than fine structure.

Circulating miR-34a levels are reduced in colorectal cancer.

INTRODUCTION: MicroRNAs (miRNAs) are small, non-coding RNA segments that regulate gene expression via post-transcriptional inhibition and have roles in cell differentiation, proliferation, and apoptosis. Expression differs between tumor and normal tissue in several malignancies. Most work has focused on tissue and cell expression with few reports of circulating miRNAs in colorectal cancer. Available biomarkers for colorectal cancer have limited sensitivity and specificity, thus there is a need for new markers. AIMS: This study aimed to identify miRNAs that are differentially expressed in the blood of colorectal cancer patients compared to controls and to establish if this is specific to colorectal cancer and thus could be utilized as potential tumor markers. METHODS: Blood samples were collected from 63 colorectal cancer patients and 45 controls. Expression of 7 target miRNAs (miR-143, miR-145, miR-21, miR-30a-3p, miR-31, miR-34a, and miR-92) was measured using RQ-PCR. Results were correlated with clinicopathological data and analyzed. Analysis of differentially expressed circulating miRNAs was expanded to include 62 patients with prostate, renal, breast, and melanoma cancers. RESULTS: Analysis of the relative quantification of the target miRNAs showed significantly reduced expression (P = 0.004) of miR-34a in colorectal cancer. MiR-34a was also significantly reduced in breast cancer (P = 0.019). CONCLUSION: This study demonstrates significantly reduced expression of circulating miR-34a in colorectal and breast cancer. This may have future application as part of a biomarker profile.

Binder syndrome.

UNLABELLED: Patients with chondrodysplasia punctata (CDP) usually present with Binder-type features, and often CDP is misdiagnosed as Binder syndrome. This study reviewed the management and outcome of patients with Binder syndrome and CDP in a multidisciplinary setting. METHODS: The notes and radiographs of the patients managed at the Australian Craniofacial Unit with a multidisciplinary setting since 1976 were reviewed, and data were collected on patient demographics, associated medical and surgical problems, subsequent management, and complications. RESULTS: Seventy-seven patients were treated over the 30-year period (5 patients were lost to follow-up); of the remaining 72 patients, 60 (83%) had Binder syndrome, and 12 (17%) were patients with CDP. Forty were males, and 32 were females, with an age range of 6 months to 47 years. Thirteen patients (18%) had a strong family history, and 65 patients (90%) have so far undergone surgical correction, and of those, 35 (54%) have completed their treatment, the longest follow-up time being 18 years. The mean number of surgical procedures was 2.4, and 18 patients (28%) had postoperative complications, which included partial necrosis of the maxilla, osteomyelitis of the mandible, facial nerve and inferior alveolar nerve neuropraxia, nasal bone graft exposure, and cellulitis. DISCUSSION: Because of the phenotypic characteristics shared by both Binder syndrome and CDP, it is most likely that Binder syndrome is not a syndrome, nor is it an entity, but most likely to be an "association." We would advocate that these patients should be managed in a multidisciplinary setting.

Readiness of obstetric professionals to inform parents regarding potential outcome of premature infants.

Parents often regard obstetric professionals as an important source of information regarding prematurity. However, there is no information regarding the readiness of these obstetric professionals to inform expectant parents of the potential outcomes of premature infants. Using a self-report questionnaire, we determined the knowledge of obstetric professionals regarding outcomes of premature infants, and gauged their confidence in providing this information to expectant parents. Some 50% of obstetric professionals reported that they 'struggle to answer parental questions' regarding premature infants. The majority of obstetric professionals correctly identified potential morbidities of prematurity, but compared to neonatal professionals, they were less likely to discuss this information with parents. When they do provide information to parents, obstetric professionals were least likely to discuss neurological morbidities. Our study has identified an important barrier to the effective transfer of neonatal outcomes information to expectant parents. This limitation requires further investigation and intervention.

A randomized factorial trial of internet-delivered cognitive behavioural therapy: An 8-week program with or without extended support and booster lesson.

While internet-delivered cognitive behavioural therapy (ICBT) is effective, some patients suggest extended support post-treatment could improve care. In this randomized factorial trial, we examined the benefits of an 8-week therapist-assisted ICBT program offered with or without an optional 4-week extension of support (Factor 1) and with or without an optional booster lesson (Factor 2). Patients screened for ICBT for depression and/or anxiety were randomly assigned to the conditions (N = 434) and we examined the use of the extension and booster, differences between those who did or did not use extension or booster, and the impact of the extension or booster on outcomes, engagement, and satisfaction at 26-weeks post-enrollment. Therapists recorded time and observations with offering support during the extension and booster. In the extension group, 54.4% (n = 56) requested the extension, while in the booster group 50.9% (n = 56) accessed the booster, and in the combined group, 41.6% (n = 47) requested the extension and 51.3% (n = 58) accessed the booster. Those who requested the extension were older, and more likely to report medication and mental health service use and severe mental health-related disability at pre-treatment; they also reported putting less effort into ICBT and finding skills more difficult. The booster was more often used among those with lower symptom severity, and those who put more effort into and had more positive experiences with ICBT. As expected, those assigned to extension sent more messages to their therapist, and those assigned to booster logged in more often. Therapists also took more time to deliver ICBT with an extension (>18 min) or booster (>13 min) compared to the 8-week program, and perceived extension and booster as beneficial for some, but not all patients. Treatment satisfaction was high across conditions, and effect sizes were large from pre-treatment to 26-week follow-up on most measures. No significant group differences were found in this study. Lack of group differences, however, could reflect low use of the extension and booster. Results provide helpful information about the demand for extensions and boosters, and provide directions for future research.

Cost-effectiveness of varying degrees and models of therapist-assisted transdiagnostic internet-delivered cognitive behaviour therapy: Evidence from a randomized controlled trial.

In routine care, Internet-delivered Cognitive Behaviour Therapy (ICBT) is often delivered with therapist support via emails/phone calls, but the cost-effectiveness of varying amounts of therapist support or having therapists specialized in ICBT is not known. This study compared the cost-effectiveness of specialized therapists providing ICBT support once-weekly (1WS) versus providing support once-weekly supplemented with a one-business-day response to patient emails (1W/1BD-S). We further compared the cost-effectiveness of 1W support offered by therapists employed in a specialized clinic (1WS) versus community clinics where therapists primarily deliver face-to-face therapy (1WC). Patients were randomly allocated to groups: 1WS group (n = 216), 1W/1BD-S group (n = 233), and 1WC group (n = 226). At baseline, 12, 24 and 52-week follow-up, patients completed the Treatment Inventory of Costs in Patients with Psychiatric Disorders questionnaire (TiC-P) adapted for use in Canada to assess healthcare use and productivity losses. Additionally, to assess Quality Adjusted Life Years (QALYs) gained, patients completed the EQ-5D-5L at the same time periods. We quantified uncertainties by one-way and probabilistic sensitivity analysis and reported Incremental cost-effectiveness ratios (ICER), cost-effectiveness planes and acceptability curves. Cost-effectiveness over 52 weeks was CAD 3072/QALY for 1WC, CAD 3244/QALY for 1W/1BD-S, and CAD 3528/QALY for 1WS. Our model suggests that 1WS is the best strategy since the incremental cost per QALY is below the $50,000 threshold (ICER is CAD 42,328/QALY compared to the next most effective, 1WC). 1W/1BD-S is dominated by the other strategies. The cost-effectiveness acceptability curves suggest that the 1WS group has a higher probability for cost-effectiveness (38 %) than 1W/1BD-S (30 %) and 1WC (32 %) when the willingness to pay is $50,000 per QALY. These results have important implications for health policymakers deciding on delivery of ICBT for the treatment of anxiety and/depressive disorders.

Prevalence of lower limb venous disease in surgeons: a case study and results of a survey by the BAOMS Reconstruction Surgical Subspecialty Interest Group.

We report a case of venous leg ulceration in a reconstructive oral and maxillofacial surgeon. An online survey was created by the British Association of Oral and Maxillofacial Surgeons (BAOMS) Reconstruction Surgical Subspecialty Interest Group (SSIG), primarily to target head and neck surgeons, to investigate the perceived risk and occurrence of venous leg disease. Two respondents had received treatment for lower limb venous disease thus compromising their ability to work, while 13 had symptoms of early venous disease. Our study shows an interesting area of concern for occupational health in surgeons, particularly in those carrying out long operations, as will be the case for members of the Reconstruction SSIG.

Corrigendum to "Transdiagnostic internet-delivered cognitive behaviour therapy with therapist-support offered once-weekly or once-weekly supplemented with therapist support within one-business-day: Pragmatic randomized controlled trial" [Internet Interv. 22 (2020) 1-16/100347].

Transdiagnostic Internet-delivered cognitive behaviour therapy with therapist support offered once-weekly or once-weekly supplemented with therapist support within one-business-day: Pragmatic randomized controlled trial.

In routine care, internet-delivered cognitive behaviour therapy (iCBT) regularly includes therapist support delivered via secure email, but the optimal response time to emails is unknown. In this study, we compared the benefits of therapists providing support once-weekly versus therapists providing support once-weekly supplemented with a one-business-day response to all patient emails. This pragmatic randomized controlled trial included therapists employed by a specialized iCBT clinic or community mental health clinics, where providing iCBT is a secondary service. Patients with depression and/or anxiety who enrolled in transdiagnostic iCBT (5 core lessons over 8 weeks) were randomized to: 1) once-weekly support supplemented with a one-business-day response to patient emails by specialized therapists (n = 233); 2) once-weekly support also offered by specialized therapists (n = 216); or 3) once-weekly support offered by community clinic therapists (n = 226). Outcomes were measured at 8, 12, 24, and 52-weeks post-enrollment. Patient engagement and treatment experiences (e.g., treatment satisfaction, therapist alliance) were also assessed and a focus group was conducted with therapists. Supplementing once-weekly therapist support with a one-business-day response to patient emails resulted in therapists sending more emails to patients (M: 13 versus 9) and required more therapist time over treatment (M: 155 versus 109 min), but was not associated with improved outcomes, patient engagement or treatment experiences. All groups showed large improvements in symptoms of depression and anxiety maintained at 52-week follow-up, strong engagement and positive treatment experiences. Therapists viewed challenges of responding to patient emails within one-business-day to outweigh benefits. Contrary to expectations, supplementing once-weekly therapist support with a one-business-day response to all patient emails did not benefit patients and increased therapist time as well as therapist challenges when delivering iCBT in routine care.

A pragmatic factorial randomized controlled trial of transdiagnostic internet-delivered cognitive behavioural therapy: Exploring benefits of homework reflection questionnaires and twice-weekly therapist support.

With the growing demand for internet-delivered cognitive behavioural therapy (iCBT), this pragmatic factorial (2 × 2 × 2) randomized controlled trial evaluated strategies for facilitating iCBT engagement and outcomes in routine care. Specifically, the benefits to patients and therapists of using homework reflection questionnaires and offering patients twice-weekly therapist support were examined. Patients (n = 632) accepted into iCBT for depression and/or anxiety were randomly assigned to complete homework reflection questionnaires or not (factor 1), receive once- or twice-weekly support (factor 2), and to receive care from therapists employed in one of two settings (iCBT clinic or a community mental health clinic; factor 3). Outcomes were measured at pre-treatment, and 8, 12, and 24-weeks post-enrollment. Therapist time was tracked and a focus group was conducted to examine therapist experiences. No differences in patient outcomes were found between therapists employed in the two settings; as such, these two groups were combined for further analyses. In terms of engagement, homework reflection questionnaires were associated with fewer website log-ins and days accessing iCBT; twice-weekly support was associated with more patient emails sent to therapists. Despite engagement differences, homework reflection questionnaires and twice-weekly support did not significantly impact primary outcomes; all groups showed large improvements in depression and anxiety that were maintained at 24-week follow-up. Therapists perceived a number of benefits and challenges associated with responding to homework reflection questionnaires and offering twice-weekly support; most notably the strategies did not benefit all patients. Twice-weekly support was associated with increased therapist time and organizational challenges. It is concluded that neither completion of homework questionnaires nor offering twice-weekly support significantly improve iCBT in routine care.
