RESUMO

BACKGROUND AND AIMS: The American Society for Gastrointestinal Endoscopy (ASGE) AI Task Force along with experts in endoscopy, technology space, regulatory authorities, and other medical subspecialties initiated a consensus process that analyzed the current literature, highlighted potential areas, and outlined the necessary research in artificial intelligence (AI) to allow a clearer understanding of AI as it pertains to endoscopy currently. METHODS: A modified Delphi process was used to develop these consensus statements. RESULTS: Statement 1: Current advances in AI allow for the development of AI-based algorithms that can be applied to endoscopy to augment endoscopist performance in detection and characterization of endoscopic lesions. Statement 2: Computer vision-based algorithms provide opportunities to redefine quality metrics in endoscopy using AI, which can be standardized and can reduce subjectivity in reporting quality metrics. Natural language processing-based algorithms can help with the data abstraction needed for reporting current quality metrics in GI endoscopy effortlessly. Statement 3: AI technologies can support smart endoscopy suites, which may help optimize workflows in the endoscopy suite, including automated documentation. Statement 4: Using AI and machine learning helps in predictive modeling, diagnosis, and prognostication. High-quality data with multidimensionality are needed for risk prediction, prognostication of specific clinical conditions, and their outcomes when using machine learning methods. Statement 5: Big data and cloud-based tools can help advance clinical research in gastroenterology. Multimodal data are key to understanding the maximal extent of the disease state and unlocking treatment options. Statement 6: Understanding how to evaluate AI algorithms in the gastroenterology literature and clinical trials is important for gastroenterologists, trainees, and researchers, and hence education efforts by GI societies are needed. Statement 7: Several challenges regarding integrating AI solutions into the clinical practice of endoscopy exist, including understanding the role of human-AI interaction. Transparency, interpretability, and explainability of AI algorithms play a key role in their clinical adoption in GI endoscopy. Developing appropriate AI governance, data procurement, and tools needed for the AI lifecycle are critical for the successful implementation of AI into clinical practice. Statement 8: For payment of AI in endoscopy, a thorough evaluation of the potential value proposition for AI systems may help guide purchasing decisions in endoscopy. Reliable cost-effectiveness studies to guide reimbursement are needed. Statement 9: Relevant clinical outcomes and performance metrics for AI in gastroenterology are currently not well defined. To improve the quality and interpretability of research in the field, steps need to be taken to define these evidence standards. Statement 10: A balanced view of AI technologies and active collaboration between the medical technology industry, computer scientists, gastroenterologists, and researchers are critical for the meaningful advancement of AI in gastroenterology. CONCLUSIONS: The consensus process led by the ASGE AI Task Force and experts from various disciplines has shed light on the potential of AI in endoscopy and gastroenterology. AI-based algorithms have shown promise in augmenting endoscopist performance, redefining quality metrics, optimizing workflows, and aiding in predictive modeling and diagnosis. However, challenges remain in evaluating AI algorithms, ensuring transparency and interpretability, addressing governance and data procurement, determining payment models, defining relevant clinical outcomes, and fostering collaboration between stakeholders. Addressing these challenges while maintaining a balanced perspective is crucial for the meaningful advancement of AI in gastroenterology.

RESUMO

The lower hybrid drift wave (LHDW) has been a candidate for anomalous resistivity and electron heating inside the electron diffusion region of magnetic reconnection. In a laboratory reconnection layer with a finite guide field, quasielectrostatic LHDW (ES-LHDW) propagating along the direction nearly perpendicular to the local magnetic field is excited in the electron diffusion region. ES-LHDW generates large density fluctuations (δn_{e}, about 25% of the mean density) that are correlated with fluctuations in the out-of-plane electric field (δE_{Y}, about twice larger than the mean reconnection electric field). With a small phase difference (∼30°) between two fluctuating quantities, the anomalous resistivity associated with the observed ES-LHDW is twice larger than the classical resistivity and accounts for 20% of the mean reconnection electric field. After we verify the linear relationship between δn_{e} and δE_{Y}, anomalous electron heating by LHDW is estimated by a quasilinear analysis. The estimated electron heating is about 2.6±0.3 MW/m^{3}, which exceeds the classical Ohmic heating of about 2.0±0.2 MW/m^{3}. This LHDW-driven heating is consistent with the observed trend of higher electron temperatures when the wave amplitude is larger. Presented results provide the first direct estimate of anomalous resistivity and electron heating power by LHDW, which demonstrates the importance of wave-particle interactions in magnetic reconnection.

RESUMO

BACKGROUND: Vision health is crucial for many aspects of life especially in developing populations such as children and adolescents. However, there is a high proportion of children and adolescents who suffer from visual impairments. Notably, accumulating evidence indicates that meeting the 24-hour movement behaviors (24-HMB) guidelines is associated with positive physical and mental health outcomes in children and adolescents. However, the relationship between being prescribed eyeglasses/contact lenses and meeting the 24-HMB guidelines has yet to be investigated. Thus, this study aimed to address this gap in the existing literature by using the 2021 National Survey of Children's Health (NSCH) dataset. METHODS: In this cross-sectional study, data was retrieved from the 2021 NSCH. A total of 14,193 U.S. children and adolescents aged between 6 and 17 years were included for data analyses. We used items of the NSCH concerning the 24-HMB guidelines (i.e., physical activity, screen time, and sleep duration) and prescription of eyeglasses/contact lenses that were answered by the legal guardian of the children. Binary logistic regression was performed to investigate whether meeting the 24-HMB guidelines is associated with prescription eyeglasses/contact lenses and whether wearing eyeglasses/contact lenses predicts adherence to the 24-HMB guidelines among children and adolescents. RESULTS: More than half of the participants (59.53%) wore eyeglasses/contact lenses and only 8.40% of them met all three of the 24-HMB guidelines. Compared to meeting none of the 24-HMB guidelines, meeting one (OR = 0.76, 95% CI = 0.62-0.93, p = 0.008), two (OR = 0.54, 95% CI = 0.43-0.67, p < 0.001), and all three 24-HMB guidelines (OR = 0.47, 95% CI = 0.34-0.64, p < 0.001) were associated with a lower risk of being prescribed eyeglasses/contact lenses among children and adolescents. CONCLUSIONS: The findings of the current study provided evidence that the prevalence of U.S. children and adolescents aged between 6 and 17 years who wore eyeglasses/contact lenses was relatively high. Furthermore, meeting the 24-HMB guidelines was associated with a lower risk of being prescribed eyeglasses/contact lenses. Future studies focusing on the effects of 24-HMB interventions on vision health among children and adolescents are needed to better inform public health actions.

RESUMO

Background: Glenoid bone loss is a risk factor leading to the failure of arthroscopic Bankart repair. While 20-25% glenoid bone loss has long been considered the level to necessitate bony augmentation, recent studies indicate that 13.5% has a "subcritical" glenoid bone loss level, which is associated with decreased short- and medium-term functional scores. Few researchers worked on the long-term effect of "subcritical" or even less severe degrees of glenoid bone loss on redislocation rates and functional outcomes after arthroscopic Bankart repair. This study aimed to evaluate the effect of subcritical or less severe glenoid bone loss on redislocation rates and function after arthroscopic Bankart repair. Methods: A patient cohort who had undergone computed tomography (CT) of glenoid bone loss and arthroscopic Bankart repair over 15 years ago was reviewed. Western Ontario Shoulder Instability (WOSI) score, Single Assessment Numeric Evaluation (SANE) score, redislocation after operation, mechanism of recurrence, and revision details were reviewed. Results: Seventy-five patients were reassessed 17.6 ± 1.9 years following initial surgery. The age at enrolment was 26.8 ± 8.3 years. Twenty-two (29%) patients of the 75 patients had a redislocation on long-term follow-up, though this was not related to glenoid bone loss severity. The impaired functional score was found in patients with initial glenoid bone loss of 7% or more on long-term follow-up: WOSI (physical symptoms): 0.98 ± 2.00 vs 2.25 ± 4.01, p=0.04 and WOSI (total): 0.79 ± 1.43 vs 1.88 ± 3.56, p=0.04. Conclusions: At a mean of 17.5 years following arthroscopic Bankart repair, redislocation occurs in over a quarter of 75 patients, and they are not related to initial glenoid bone loss severity. Impaired functional outcome is apparent in patients with initial glenoid bone loss of >7%, though this impairment does not seem sufficiently severe to warrant an alternative treatment approach.

RESUMO

Background: This study aimed to investigate the correlations of serum vitamin D insufficiency with quadriceps neuromuscular function in patients with anterior cruciate ligament (ACL) injury. Methods: A cross-sectional study was conducted. Eighteen patients with a primary, unilateral ACL injury who had insufficient serum vitamin D concentrations (<30 ng/ml) were recruited for the study. Bilateral quadriceps neuromuscular function, including maximal strength, the speed of rapid contraction, and inhibition, were measured on an isokinetic dynamometer with the hip and the knee joint flexion at 90° and 45°, respectively. Quadriceps strength was measured by maximal voluntary isometric contractions (MVIC); the speed of rapid contraction was quantified by the rate of torque development (RTD), which was divided into the early (RTD0-50) and the late phase (RTD100-200); quadriceps inhibition was quantified by the central activation ratio (CAR). Serum vitamin D concentration was quantitatively determined by serum 25(OH)D concentration measured by the 25(OH)D ELISA kit. The Spearman rank correlation analysis was used to examine the correlation between the vitamin D concentration and bilateral quadriceps MVIC, RTD0-50, RTD100-200, and CAR, respectively. Results: The results of Spearman rank correlation analyses showed that the serum 25(OH)D concentration was significantly correlated with bilateral quadriceps MVIC (injured: r = 0.574, p = 0.013; uninjured: r = 0.650, p = 0.003) and RTD0-50 (r = 0.651, p = 0.003), and CAR (r = 0.662, p = 0.003) on the uninjured limb. However, no significant correlations were found between the serum 25(OH)D concentration and the other outcomes. Conclusions: The serum vitamin D concentration correlates with quadriceps neuromuscular function in patients with ACL injury who had vitamin D insufficiency.

RESUMO

BACKGROUND: This study aimed to investigate associations of meeting 24-h movement behavior (24-HMB: physical activity [PA], screen time [ST] in the school-aged youth, and sleep) guidelines with indicators of academic engagement, psychological functioning, and cognitive function in a national representative sample of U.S. youth. METHODS: In this cross-sectional study, 1794 participants aged 6 to 17 years old were included for multivariable logistic regression to determine the above-mentioned associations, while adjusting for sociodemographic and health covariates. RESULTS: The proportion of participants who met 24-HMB guideline(s) varied greatly (PA+ ST+ sleep = 34 [weighted 1.17 %], PA + ST = 23 [weighted 1.72 %], PA + sleep = 52 [weighted 2.15 %], PA = 34 [weighted 2.88 %], ST = 142 [weighted 7.5 %], ST+ sleep = 209 [weighted 11.86 %], sleep = 725 [weighted 35.5 %], none = 575 [weighted 37.22 %]). Participants who met ST guideline alone and integrated (ST + Sleep and ST + sleep + PA) guidelines demonstrated the consistently beneficial associations with learning interest/curiosity, caring for school performance, completing required homework, resilience, cognitive difficulties, self-regulation (ps < 0.05). CONCLUSION: Meeting 24-HMB guidelines in an isolated or integrative manner was associated with improved academic engagement, psychological functioning, and reduced cognitive difficulties. These findings highlight the importance of the promotion of 24-HMB guidelines in youth with internalizing problems. Future longitudinal studies are needed to investigate whether changes or modifications of meeting specific 24-HMB guidelines (especially ST) is beneficial for youth with internalizing problems.

RESUMO

CLINICAL RELEVANCE: Interpersonal skills are crucial for successful clinician-patient interactions. To prepare future optometrists for clinical practice, pedagogical evaluation is important to support the implementation of new strategies for teaching and evaluating interpersonal skills. BACKGROUND: Optometry students largely develop their interpersonal skills through in-person patient interactions. Telehealth is increasing, yet strategies to develop the interpersonal skills of students for teleconsulting have not been explored. This study aimed to assess the feasibility, effectiveness and perceived usefulness of an online, multisource (patients, clinicians and students) evaluation and feedback program for developing interpersonal skills. METHODS: Via an online teleconferencing platform, optometry students (n = 40) interacted with a volunteer patient, observed by a teaching clinician. Patients and clinicians evaluated the interpersonal skills of the student in two ways: (1) qualitative written feedback, and (2) quantitative rating (Doctors' Interpersonal Skills Questionnaire). All students received written patient and clinician feedback after the session, but not their quantitative ratings. A subset of students (n = 19) completed two sessions, self-ratings, and were provided with their written feedback and an audiovisual recording from their first interaction before completing the second session. All participants were invited to complete an anonymous survey at program completion. RESULTS: Patient and clinician overall interpersonal skills ratings were positively correlated (Spearman's r = 0.35, p = 0.03) and showed moderate agreement (Lin's concordance coefficient = 0.34). Student self-ratings did not match patient ratings (r = 0.01, p = 0.98), whereas there was moderate agreement between clinician and student ratings (Lin's concordance coefficient = 0.30). Ratings improved at the second visit (p = 0.01). Patient ratings were higher than clinicians (p = 0.01) and students (p = 0.03). All participants agreed that the program was feasible, useful and effective at fostering good interpersonal skills. CONCLUSION: Multisource feedback about interpersonal skills contributes to improvement in student performance. Patients and clinicians can evaluate and provide useful feedback to optometry students about their interpersonal skills using online methods.

RESUMO

OBJECTIVE: This cross-sectional study examined the relationships between adherence to 24-HMB guidelines (including physical activity [PA], screen time [ST], and sleep) with academic performance and psychological functioning among children and adolescents with depression. METHODS: This study consists of 2165 participants aged 6-17 years with depression. Independent variables were components of 24-HMB guideline adherence, while outcomes of interest were academic performance (i.e., caring about school performance and completion of required homework) and psychological functioning (i.e., resilience and self-regulation). Logistic regression analysis was conducted while adjusting for confounding variables. RESULTS: Only 1.03 % of the participants adhered to PA + ST + Sleep guidelines. Compared to non-adherence, adherence to PA + ST guidelines was significantly linked to a greater likelihood of caring about school performance (OR = 2.17), while ST + Sleep guidelines adherence was significantly linked to a greater likelihood of caring about school performance (OR = 2.02), completing homework (OR = 2.91), resilience (OR = 2.51), and self-regulation (OR = 2.51). Furthermore, adherence to PA + ST + Sleep guidelines was significantly linked to a higher likelihood of caring about school performance (OR = 5.01), resilience (OR = 2.49), and self-regulation (OR = 2.88) among these participants with depression. CONCLUSION: Adhering to 24-HMB guidelines is positively linked to academic performance and psychological functioning among children and adolescents with depression. Thus, establishing healthy lifestyle behaviors should be promoted in school settings.

RESUMO

Suprachoroidal hemorrhage (SCH) is an uncommon sight-threatening pathology, most often encountered intraoperatively. However, spontaneous presentation of SCH is even rarer. We report the case of a 69-year-old diabetic patient with spontaneous SCH (SSCH) in her left eye masquerading as a vitreous hemorrhage. She developed treatment-resistant secondary angle-closure glaucoma. She was referred to the vitreoretinal team for intraocular exploration to identify the source of the hemorrhage. Pars plana vitrectomy identified extensive SCH intraoperatively. As far as the authors are aware, this is the first case in which the patient had such severe SSCH that the characteristic kissing choroidal sign was not visualized on repeated examinations and multimodal imaging. All initial evidence pointed towards a diagnosis of vitreous hemorrhage. This case demonstrates that if a patient has angle-closure glaucoma and persistently raised intra-ocular pressure that is treatment-resistant, then SCH is an important differential diagnosis to consider. Clinicians need to be aware of the risk factors of SCH, and early recognition with a timely intervention of SCH is important to optimize visual outcomes.

RESUMO

BACKGROUND: This study investigated the accuracy in achieving proper lower limb alignment and component positions after total knee replacement (TKR) with image-free and image-based robotic-assisted TKR. METHODS: A total of 129 patients (166 knees) suffering from end-stage knee arthritis who underwent TKA operated by robotic-assisted surgery between the years 2018 and mid-2021 were recruited. Radiological outcomes were compared between image-free and image-based robotic-assisted surgical systems. RESULTS: There were significant differences between the two robotic systems when comparing the mean planned component alignment and the mean measured alignment on radiographs, in which the image-free robotic-assisted system was more varus, whereas the image-based robotic-assisted system was more valgus for both the mean femoral and tibial component coronal alignment (p < 0.001). For tibial component sagittal alignment, the image-based group had a larger deviation from the planned posterior slope (p < 0.001). CONCLUSION: Image-free and image-based robotic assisted TKR had differing accuracy in femoral and tibial alignment.

RESUMO

PURPOSE: To assess the impact of the junior doctors' industrial action on one of the largest emergency eye departments (EED) in the United Kingdom. METHODS: We compared staff allocation, patient presentation, time in streaming, time in the department, the Manchester Triage System (MTS) score, number of eye emergencies and follow-up care of patients who attended the EED in the Manchester Royal Eye Hospital (MREH) during the 3-day industrial action (13-15 March 2023) compared with control periods 2 weeks before and 2 weeks after the industrial action. RESULTS: During the industrial action, there were almost 1.5 times more staff allocated to EED with a near doubling of the senior workforce. There was no difference in patient presentation, MTS score, number of eye emergencies or patient follow-up during the industrial action. However, patients had significantly less time in streaming (p < 0.001) and in the department (p < 0.001) during the industrial action compared to control periods. CONCLUSION: Emergency ophthalmic patient care was not compromised during the industrial action due to the reallocation of the workforce to EED. The results of this study may help in the planning of ophthalmic eye-care services in the event of future industrial actions.

RESUMO

Social support is a crucial factor that can facilitate regular engagement in physical activity. To assess the influence of social factors on the level of regular physical activity, the Physical Activity and Social Support Scale (PASSS) has been developed. However, the PASSS has yet to be validated in a Chinese sample of established adults. To address this gap in the literature, this study describes the development and psychometric evaluation of a Chinese version of the PASSS (PASSS-C) for established adults. PASSS-C was validated for a Chinese sample of adults aged between 30 and 45 years old (N = 1799). Structural validity was evaluated using confirmatory factor analysis (CFA) with Maximum Likelihood Method (MLM). Spearman's correlations between the PASSS-C and the International Physical Activity Questionnaire - Short Form (IPAQ-SF), the Social Support Rating Scale - Chinses Version (SSRS-C), and the Affective Exercise Experience Scale - Chinese Version (AFFEXX-C) were determined to examine the criterion validity. Cronbach's alpha coefficients and McDonald's omega coefficients were used to assess the internal consistency of the total scale and sub-scales of the PASSS-C. The results of the CFA suggest that the five-factor model had an acceptable fit (CFI = 0.99, GFI = 0.99, SRMR = 0.01, RMSEA = 0.02). Cronbach's alpha and McDonald's omega for the PASSS-C and its sub-scales ranged from 0.81 to 0.96. The results indicate that the PASSS-C has acceptable psychometric properties. Thus, the scale can be used to assess the levels of social support for physical activity in Chinese established adults.

RESUMO

BACKGROUND: Over the last decade, the treatment landscape for moderate-severe psoriasis has rapidly evolved. The Australasian College of Dermatologists sought to review and update previously published treatment goals for moderate-severe psoriasis. METHODS: A modified Delphi approach was used. Comprehensive literature review and guideline evaluation resulted in the development of statements and other questions to establish current clinical practices. Two rounds of anonymous voting were undertaken, with a collaborative meeting held in between to discuss areas of discordance. Overall, consensus was defined as achievement of ≥75% agreement in the range 7-9 on a 9-point scale (1 strongly disagree; 9 strongly agree). RESULTS: Consensus was achieved on 26/29 statements in round 1 and a further 20 statements in round 2. There was strong agreement to expanding the classification/definition of psoriasis severity by including a choice of metrics, incorporating quality of life measures, and widening the scope of high-impact sites. Consensus was also reached on revised treatment response criteria, which were then incorporated into a new treatment algorithm. There was discordance with the current requirement to undertake a trial with established systemic agents before accessing targeted therapy. CONCLUSION: The ability of new targeted treatment options to change the narrative in psoriasis patient care can only be properly realised if challenges to timely and equitable access are addressed. The proposed framework for the assessment, classification and management of moderate-severe psoriasis aligns with international recommendations. Its adoption into Australian clinical practice is hoped to improve treatment outcomes and patients' satisfaction with their care.

RESUMO

BACKGROUND: Persistent anterior knee pain and subsequent patellofemoral joint (PFJ) osteoarthritis (OA) are common symptoms after anterior cruciate ligament reconstruction (ACLR). Quadriceps weakness and atrophy is also common after ACLR. This can be contributed by arthrogenic muscle inhibition and disuse, caused by joint swelling, pain, and inflammation after surgery. With quadriceps atrophy and weakness are associated with PFJ pain, this can cause further disuse exacerbating muscle atrophy. Herein, this study aims to identify early changes in musculoskeletal, functional and quality of health parameters for knee OA after 5 years of ACLR. METHODS: Patients treated with arthroscopically assisted single-bundle ACLR using hamstrings graft for more than 5 years were identified and recruited from our clinic registry. Those with persistent anterior knee pain were invited back for our follow-up study. For all participants, basic clinical demography and standard knee X-ray were taken. Likewise, clinical history, symptomatology, and physical examination were performed to confirm isolated PFJ pain. Outcome measures including leg quadriceps quality using ultrasound, functional performance using pressure mat and pain using self-reported questionnaires (KOOS, Kujala and IKDC) were assessed. Interobserver reproducibility was assessed by two reviewers. RESULTS: A total of 19 patients with unilateral injury who had undergone ACLR 5-years ago with persistent anterior knee pain participated in this present study. Toward the muscle quality, thinner vastus medialis and more stiffness in vastus lateralis were found in post-ACLR knees (p < 0.05). Functionally, patients with more anterior knee pain tended to shift more of their body weight towards the non-injured limb with increasing knee flexion. In accordance, rectus femoris muscle stiffness in the ACLR knee was significantly correlated with pain (p < 0.05). CONCLUSION: In this study, it was found that patients having higher degree of anterior knee pain were associated with higher vastus medialis muscle stiffness and thinner vastus lateralis muscle thickness. Similarly, patients with more anterior knee pain tended to shift more of their body weight towards the non-injured limb leading to an abnormal PFJ loading. Taken together, this current study helped to indicate that persistent quadriceps muscle weakness is potential contributing factor to the early development of PFJ pain.

RESUMO

Introduction: The assessment of children's motor competence is an important concern as physical inactivity has been linked with poor movement quality and aspects of well-being such as low self-esteem. The General Movement Competence Assessment (GMCA) is a new instrument that was developed using active video gaming technology. Methods: Confirmatory factor analysis was conducted to examine the internal validity of the GMCA in a sample of 253 typically developing children (135 boys and 118 girls), aged 7-12 years old (9.9 ± 1.6 years). Further, a second-order confirmatory factor analysis examined how the four constructs fit onto the higher-order variable of movement competence. Results: Results revealed that the first-order four-construct model of the GMCA was a good fit (CFI 0.98; TLI 0.98; RMSEA 0.05). The second-order confirmatory factor analysis revealed that the four constructs loaded directly onto movement competence. It accounted for 95.44% of the variance which is approximately 20% more than the first-order model. The internal structure of the GMCA identified four constructs of movement competence (i.e., stability, object-control, locomotion and dexterity) based on the study sample. Discussion: Performance trends in the general movement competence assessment support empirical evidence that movement competence improves as children age. Results suggest that active video games have considerable potential to help assess general motor competency in the wider population. Future work may consider the sensitivity of motion-sensing technologies in detecting developmental changes over time.

RESUMO

Background and Aim: Obtaining endoscopic biopsies from the ampulla of Vater is important for the diagnosis of lesions that are suspicious for neoplasia. The clinical safety profile is not well defined in the literature. Our aim was to evaluate the procedure-related readmission rate and complications from ampullary biopsy in patients undergoing duodenoscopy and endoscopic retrograde cholangiopancreatography (ERCP). Methods: A retrospective data analysis was performed on adult patients at Austin Hospital who underwent ampullary biopsies between 1 January 2010 and 1 March 12022. Medical records were identified using pathology databases. The electronic health record was reviewed for baseline characteristics including demographics, date, indication for ampullary biopsy, procedure type (duodenoscopy or ERCP), and procedural associated interventions during ERCP. Readmissions to the Austin Emergency Department within 30 days following the biopsy were identified, and complications were noted. Results: A total of 506 records were reviewed and 246 episodes of ampullary biopsy met the inclusion criteria. The procedure-related readmission rate for all episodes was 6.1%, which included pain (3.3%), pancreatitis (2.0%), cholangitis (1.6%), and bleeding (0.8%). Ampullary biopsies with ERCP had a procedure-related readmission rate of 8.4%, whereas ampullary biopsies without ERCP had a rate of 2.2%. Increased readmissions and complications were associated with male sex (P = 0.01 and P = 0.05, respectively). There was no association between the number of biopsies taken and complications. Conclusion: Performing an ampullary biopsy without an associated ERCP carries a low rate of clinical complications and procedure-related readmissions. The combination of ERCP and ampullary biopsy increases the risk four-fold.

RESUMO

INTRODUCTION: Popularity of joint replacement surgery due to ever aging population surges the demand for a proper national joint registry. Our Chinese University of Hong Kong - Prince of Wales Hospital (CUHK-PWH) joint registry has passed the 30th year. The aims of this study are 1) summarize our territory-wide joint registry which has passed the 30th year since establishment and 2) compare our statistics with other major joint registries. METHODS: Part 1 was to review the CUHK-PWH registry. Demographic characteristics of our patients who underwent knee and hip replacements had been summarized. Part 2 was a series of comparisons with registries from Sweden, UK, Australia and New Zealand. RESULTS: CUHK-PWH registry captured 2889 primary total knee replacements (TKR) (110 (3.81%) revision) and 879 primary total hip replacements (THR) (107 (12.17%) revision). Median Surgery time of TKR was shorter than THR. Clinical outcome scores were much improved after surgery in both. Uncemented of hybrid in TKR were most popular in Australia (33.4%) and 40% in Sweden and UK. More than half of TKR and THR patients showed the highest percentage with ASA grade 2. New Zealand reflected the best cumulative percentage survival 20 years after surgery of 92.2%, 76.0%, 84.2% survivorship 20 years after TKR, unicompartmental knee replacement (UKR) and Hip. CONCLUSION: A worldwide accepted patient-reported outcome measure (PROM) is recommended to develop to make comparisons among registries and studies feasible. Completeness of registry data is important and useful to improve surgical performance through data comparisons from different regions. Funding from government on sustaining registries is reflected. Registries from Asian countries have yet to be grown and reported.
