RESUMO
OBJECTIVES: Health-related quality-of-life (HRQoL) instruments for cardiovascular diseases (CVD) have been commonly used to measure important patient-reported outcomes (PROs) in clinical trials and practices. This study aimed at systematically identifying and assessing the content validity of CVD-specific HRQoL instruments in clinical studies. METHODS: The research team searched Cumulative Index to Nursing and Allied Health Literature, Embase, and PubMed from inception to January 20, 2022. The research team included studies that reported the development and content validity for CVD-specific instruments. Two reviewers independently assessed the methodological quality using the Consensus-based Standards for the Selection of Health Measurement Instruments methods on evaluating content validity of PROs. Content analysis was used to categorize the items included in the instruments. RESULTS: The research team found 69 studies reporting the content validity of 40 instruments specifically developed for CVD. Fourteen (35.0%) were rated "sufficient" with very low to moderate quality of evidence. For PRO development, all instruments were rated "doubtful" or "inadequate." Twenty-eight (70.0%) instruments cover the core concepts of HRQoL. CONCLUSIONS: The quality of development and content validity vary among existing CVD-specific instruments. The evidence on the content validity should be considered when choosing a HRQoL instrument in CVD clinical studies and health economic evaluations.

The quality of breast ultrasound images has a significant impact on the accuracy of disease diagnosis. Existing image quality assessment (IQA) methods usually use pixel-level feature statistical methods or end-to-end deep learning methods, which focus on the global image quality but ignore the image quality of the lesion region. However, in clinical practice, doctors' evaluation of ultrasound image quality relies more on the local area of the lesion, which determines the diagnostic value of ultrasound images. In this study, a global-local integrated IQA framework for breast ultrasound images was proposed to learn doctors' clinical evaluation standards. In this study, 1285 breast ultrasound images were collected and scored by experienced doctors. After being classified as either images with lesions or images without lesions, they were evaluated using soft-reference IQA or bilinear CNN IQA, respectively. Experiments showed that for ultrasound images with lesions, our proposed soft-reference IQA achieved PLCC 0.8418 with doctors' annotation, while the existing end-to-end deep learning method that did not consider the local lesion features only achieved PLCC 0.6606. Due to the accuracy improvement for the images with lesions, our proposed global-local integrated IQA framework had better performance in the IQA task than the existing end-to-end deep learning method, with PLCC improving from 0.8306 to 0.8851.
RESUMO
Here, we show that the adverse environmental and health effects of tetracycline (TC) can be efficiently reduced by encapsulating Ag3PO4 into MIL-101(Fe) to construct a Ag3PO4/MIL-101(Fe) heterojunction composite through advanced oxidation processes, such as Fenton catalysis, photocatalysis, and photo-Fenton catalysis. Notably, the reaction can be driven by natural sunlight and does not require any artificial energy source. Remarkably, the optimal degradation of TC can be achieved under different compositions of the composite system through photocatalysis and photo-Fenton catalysis. For photo-Fenton catalysis, the maximum degradation rate of TC (2.5730 min-1) is achieved when the mass ratio of MIL-101(Fe) to Ag3PO4 in the composite is 5:1, which is 31.65- and 3.12-fold of that in the Ag3PO4 + PDS + Sunlight and MIL-101(Fe) + PDS+ Sunlight catalyst systems, respectively. Moreover, the internal conversion of matrix during photocatalysis and Fenton catalysis processes inhibits the photocorrosion of Ag3PO4 and improves the reusability of the composite. Furthermore, it is found that both radical and non-radical species participate in the TC degradation. Besides, the degradation products and catalytic mechanism of Ag3PO4 and Ag3PO4/MIL-101(Fe) systems are explored. The toxicity evaluation results suggest that the intermediates produced during Ag3PO4/MIL-101(Fe) catalysis have a lower biotoxicity than those produced during Ag3PO4 catalysis. Overall, this work provides an effective strategy to inhibit the inherent photocorrosion of Ag3PO4 and establishes an efficient catalytic system for the treatment of organic-contaminated wastewater under natural sunlight conditions.

Chronic hypoparathyroidism (HypoPT) is associated with significant morbidity and impaired quality of life (QoL). The goals of management for chronic HypoPT include improvement in QoL and the prevention of both hypo- and hypercalcemia symptoms and long-term complications. Several groups have provided consensus statements and guidelines on the management of HypoPT; however, due to limited evidence, these recommendations have largely been based on literature reviews, expert opinion, and consensus statements. The objective of this study was to use a systematic approach to describe current practice for the initial assessment and follow-up of patients with chronic HypoPT. We developed a survey asking experts in the field to select the responses that best reflect their current practice. The survey found no differences in responses between nonsurgical and postsurgical patient assessment. For new patients, respondents usually performed an assessment of serum lab profile (calcium [either albumin-adjusted or ionized], magnesium, creatinine, phosphate, 25-hydroxyvitamin D), 24-hour urine (creatinine, calcium), and a renal ultrasound to evaluate for the presence of nephrocalcinosis or nephrolithiasis. For follow-up patients, most respondents perform blood tests and urine tests every 6 months or less frequently. The reported clinical practice patterns for monitoring for complications of chronic HypoPT vary considerably among respondents. Based on the responses in this systematic expert practice survey, we provide practice suggestions for initial assessment and follow-up of patients with chronic HypoPT. In addition, we highlight areas with significant variation in practice and identify important areas for future research. © 2022 The Authors.

OBJECTIVE: To comprehensively analyze the cost-utility of robotic surgery in clinical practice and to investigate the reporting and methodological quality of the related evidence. METHODS: Data on cost-utility analyses (CUAs) of robotic surgery were collected in seven electronic databases from the inception to July 2021. The quality of the included studies was assessed using the CHEERs and QHES checklists. A systematic review was performed with the incremental cost-effectiveness ratio as the outcome of interest. RESULTS: Thirty-one CUAs of robotic surgery were eligible. Overall, the identified CUAs were fair to high quality, and 63% of the CUAs ranked the cost-utility of robotic surgery as "favored," 32% categorized as "reject," and the remaining 5% ranked as "unclear." Although a high heterogeneity was present in terms of the study design among the included CUAs, most studies (81.25%) consistently found that robotic surgery was more cost-utility than open surgery for prostatectomy (ICER: $6905.31/QALY to $26240.75/QALY; time horizon: 10 years or lifetime), colectomy (dominated by robotic surgery; time horizon: 1 year), knee arthroplasty (ICER: $1134.22/QALY to $1232.27/QALY; time horizon: lifetime), gastrectomy (dominated by robotic surgery; time horizon: 1 year), spine surgery (ICER: $17707.27/QALY; time horizon: 1 year), and cystectomy (ICER: $3154.46/QALY; time horizon: 3 months). However, inconsistent evidence was found for the cost-utility of robotic surgery versus laparoscopic surgery and (chemo)radiotherapy. CONCLUSIONS: Fair or high-quality evidence indicated that robotic surgery is more cost-utility than open surgery, while it remains inconclusive whether robotic surgery is more cost-utility than laparoscopic surgery and (chemo)radiotherapy. Thus, an additional evaluation is required.

OBJECTIVES: This study aimed to conduct a systematic review of cost-utility studies of internet-based and face-to-face cognitive behavioral therapy (CBT) for depression from childhood to adulthood and to examine their reporting and methodological quality. METHODS: A structured search for cost-utility studies concerning CBT for depression was performed in 7 comprehensive databases from their inception to July 2020. Two reviewers independently screened the literature, abstracted data, and assessed quality using the Consolidated Health Economic Evaluation Reporting Standards and Quality of Health Economic Studies checklists. The primary outcome was the incremental cost-effectiveness ratio (ICER) across all studies. To make a relevant comparison of the ICERs across the identified studies, cost data were inflated to the year 2020 and converted into US dollars. RESULTS: Thirty-eight studies were included in this review, of which 26 studies (68%) were deemed of high methodological quality and 12 studies (32%) of fair quality. Despite differences in study designs and settings, the conclusions of most included studies for adult depression were general agreement; they showed that face-to-face CBT monotherapy or combination therapy compared with antidepressants and usual care for adult depression were cost-effective from the societal, health system, or payer perspective (ICER -$241 212.4/quality-adjusted life-year [QALY] to $33 032.47/QALY, time horizon 12-60 months). Internet-based CBT regardless of guided or unguided also has a significant cost-effectiveness advantage (ICER -$37 717.52/QALY to $73 841.34/QALY, time horizon 3-36 months). In addition, CBT was cost-effective in preventing depression (ICER -$23 932.07/QALY to $26 092.02/QALY, time horizon 9-60 months). Nevertheless, the evidence for the cost-effectiveness of CBT for children and adolescents was still ambiguous. CONCLUSIONS: Fair or high-quality evidence showed that CBT monotherapy or combination therapy for adult depression was cost-effective; whether CBT-related therapy was cost-effective for children and adolescents depression remains inconclusive.

OBJECTIVES: Cancer screening guidelines differ in their recommendations for or against screening. To be able to provide explicit recommendations, guidelines need to specify thresholds for the magnitude of benefits of screening, given its harms and burdens. We evaluated how current cancer screening guidelines address the relative importance of benefits versus harms and burdens of screening. DATA SOURCE: We searched the Guidelines International Network, International Guideline Library, ECRI Institute and Medline. Two pairs of reviewers independently performed guideline selection and data abstraction. ELIGIBILITY CRITERIA: We included all cancer screening guidelines published in English between January 2014 and April 2019. RESULTS: Of 68 eligible guidelines, 25 included a statement regarding the trade-off between screening benefits versus harms and burdens (14 guidelines), or a statement of direction of the net effect (defined as benefits minus harms or burdens) (13 guidelines). None of these 25 guidelines defined how large a screening benefit should be to recommend screening, given its harms and burdens. 11 guidelines performed an economic evaluation of screening. Of these, six identified a key benefit outcome; two specified a cost-effectiveness threshold for recommending a screening option. Eight guidelines commented on people's values and preferences regarding the trade-off between benefits versus harms and burdens. CONCLUSIONS: Current cancer screening guidelines fail to specify the values and preferences underlying their recommendations. No guidelines provide a threshold at which they believe the benefits of screening outweigh its harms and burdens. PROSPERO REGISTRATION NUMBER: CRD42019138590.

OBJECTIVES: The aim of the study was to assess the quality of guidelines on irritable bowel syndrome (IBS) using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument and identify concordance of different commendations. MATERIALS AND METHODS: A systematic search was undertaken from inception to May 2018. Two reviewers independently selected the titles and abstracts. The guidelines included were assessed using the AGREE II instrument. The consistency of evaluations was calculated using intra-class correlation coefficients with 95% CI. RESULTS: From 994 records, 7 guidelines were included. Most of guidelines got a moderate score of AGREE II. The highest median scores were achieved for scope and purpose and clarity and presentation (69.4%), while the lowest median scores across guidelines were for applicability (50.0%). Most of the nonpharmacologic management recommendations for IBS were similar. However, there also existed some differences on pharmacologic between different guidelines. CONCLUSIONS: The guidelines on IBS varied in quality and there were discrepancies about recommendations and recommendation grades. There is some space to improvement the quality of methodological rigor in development and reporting within clinical guidelines.

OBJECTIVE: This study aimed to assess the registration quality of clinical trials (CTs) with traditional Chinese medicine (TCM) in the WHO International Clinical Trials Registry Platform (ICTRP) and identify the common problems if any. METHODS: The ICTRP database was searched for all TCM CTs that were registered up to 31 December 2017. Registered information of each trial was collected from specific registry involved in ICTRP through hyperlink. The primary analysis was to assess the reporting quality of registered trials with TCM interventions, which is based on the minimum 20 items of WHO Trial Registration Data Set (TRDS, V.1.2.1) plus optional additional three items recommended by ICTRP, and some specific items for TCM information (including TCM intervention, diagnosis, outcome and rationale). Descriptive statistics were additionally used to analyse the baseline characteristics of TCM trial registrations. RESULTS: A total of 3339 records in 15 registries were examined. The number of TCM registered trials has increased rapidly after the requirement of mandatory trial registration proposed by International Committee of Medical Journal Editors on 1 July 2005, and the top two registries were Chinese Clinical Trial Registry and ClincialTrials.gov. Of 3339 trials, 61% were prospective registration and 12.8% shared resultant publications. There were 2955 interventional trials but none of them had a 100% reporting rate of the minimum 20 items and additional three items. The reporting quality of these 23 items was not optimal due to 11 of them had a lower reporting rate (<65%). For TCM details, 49.2% lacked information on description of TCM intervention(s), 85.9% did not contain TCM diagnosis criteria, 92.6% did not use TCM outcome(s) and 67.1% lacked information on TCM background and rationale. CONCLUSION: The registration quality of TCM CTs should be improved by prospective registration, full completion of WHO TRDS, full reporting of TCM information and results sharing. Further full set of trial registration items for TCM trials should be developed thus to standardise the content of TCM trial registration.

OBJECTIVES: The aim of this study was to investigate the quality of clinical practice guidelines of cancer cachexia and identify gaps limiting knowledge. METHODS: A systematic search of relevant guideline websites and literature databases (including PubMed, NCCN, NGC, SIGN, NICE, and google) was undertaken from inception to March 2017 to identify and select clinical guidelines related to cancer cachexia. Four independent reviewers assessed the eligible guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. Agreement among reviewers of the guidelines was measured by using intra-class correlation coefficient (ICC). The number of recommendations, strength of recommendation, and levels of evidence were determined. RESULTS: Nine cancer cachexia guidelines published from 2006 to 2017 were identified. An overall high degree of agreement among reviewers to each domain was observed (ICC ranged from 0.75 to 0.91). The median scores and range for each AGREE II domain were as follows: (i) scope and purpose (medianâ¯=â¯61.1%, range: 13.9% to 80.7%); (ii) stakeholder involvement (medianâ¯=â¯26.4%, range: 8.3% to 81.9%); (iii) rigour of development (medianâ¯=â¯35.9%, range: 3.6% to 84.4%); (iv) clarity and presentation (medianâ¯=â¯56.9%, range: 30.6% to 76.4%); (v) applicability (medianâ¯=â¯19.8%, range: 0% to 77.1%) and (vi) editorial independence (medianâ¯=â¯27.1%, range: 0% to 85.4%). Two cancer cachexia guidelines (ESPEN, 2017 and University of Queensland, 2013) scored higher on all domains and were classified as recommended for clinical practice, among which, one was developed by European Society for Parenteral and Enteral Nutrition and European Partnership for Action Against Cancer, and the other was developed by University of Queensland. In addition, more than a half recommendations were based on nonrandomized studies (Level C, 50.0%) and expert opinion (Level D, 8.2%). CONCLUSIONS: The quality of cancer cachexia guidelines was highly heterogeneous among different domains even within the same guideline. There is significant room for improvement to develop high quality cancer cachexia guidelines, which urgently warrants first-class research to minimize the vital gaps in the evidence for formulation of cancer cachexia guidelines.

OBJECTIVES: We aimed to examine the declaration of interests (DOIs), management of conflict of interest (COI), and the funders for World Health Organization (WHO) guidelines. STUDY DESIGN AND SETTING: We examined all Guidelines Review Committee (GRC)-approved WHO guidelines published in English from January 2007 (inception of the GRC) to November 2016. We obtained a list of all such guidelines from the GRC Secretariat. Characteristics of guidelines including funders and individual contributors' DOI were independently extracted by two researchers. Binary logistic regression was used to assess the association between declarations and the number of organizations involved in development. RESULTS: A total of 176 guidelines fulfilled inclusion criteria, encompassing 14 clinical or public health fields. Funders were reported in 128 (73%) of the guidelines: the most common were governments. DOI for external contributors were reported in 157 (89%) of the guidelines: 75 (48%) indicated no contributors with COI, 57 (36%) reported contributors with COI, and 25 (16%) reported collecting DOI but not whether COI existed. Financial COI were reported more frequently than nonfinancial COI. Of 57 guidelines that reported COI, 45 (79%) indicated how the COI were managed. CONCLUSION: The majority of WHO guidelines reported their funding sources and the DOI and COI of external contributors in their guideline documents. However, there is a need for improvement, in particular for reporting of funders and their role, declaration processes, and management of COI.

Hyperthyroidism is a common condition that is associated with increased morbidity and mortality. A number of meta-analyses (MAs) have assessed the therapeutic measures for hyperthyroidism, including antithyroid drugs, surgery, and radioiodine, however, the methodological quality has not been evaluated. This study evaluated the methodological quality and summarized the evidence obtained from MAs of hyperthyroidism treatments for radioiodine, antithyroid drugs, and surgery. We searched the PubMed, EMBASE, Cochrane Library, Web of Science, and Chinese Biomedical Literature Database databases. Two investigators independently assessed the meta-analyses titles and abstracts for inclusion. Methodological quality was assessed using the validated AMSTAR (Assessing the Methodological Quality of Systematic Reviews) tool. A total of 26 MAs fulfilled the inclusion criteria. Based on the AMSTAR scores, the average methodological quality was 8.31, with large variability ranging from 4 to 11. The methodological quality of English meta-analyses was better than that of Chinese meta-analyses. Cochrane reviews had better methodological quality than non-Cochrane reviews due to better study selection and data extraction, the inclusion of unpublished studies, and better reporting of study characteristics. The authors did not report conflicts of interest in 53.8% meta-analyses, and 19.2% did not report the harmful effects of treatment. Publication bias was not assessed in 38.5% of meta-analyses, and 19.2% did not report the follow-up time. Large-scale assessment of methodological quality of meta-analyses of hyperthyroidism treatment highlighted methodological strengths and weaknesses. Consideration of scientific quality when formulating conclusions should be made explicit. Future meta-analyses should improve on reporting conflict of interest.

This meta-analysis aimed to investigate the effectiveness and safety of RAH and LLR for liver neoplasms. A systematic search was performed in PubMed, EMbase, the Cochrane Library, Web of science, and China Biology Medicine disc up to July 2016 for studies that provided comparisons between the surgical outcomes of RAH and LLR for liver neoplasms. WMD, OR and 95% CI were calculated and data combined using the random-effect model. The quality of the evidence was assessed using GRADE methods. A total of 17 studies were included in the meta-analysis, in which 487 patients were in the RAH group and 902 patients were in the LLR group. The meta-analysis results indicated: compared to LLR, RAH was associated with more estimated blood loss, longer operative time, and longer time to first nutritional intake (p < 0.05). There was no significant difference in length of hospital stay, conversion rate during operation, R0 resection rate, complications and mortality (p > 0.05). Three studies reported the total cost, and the result showed a higher cost in the RAH group when compared with the LLR group (p < 0.05). This meta-analysis indicated that RAH and LLR display similar effectiveness and safety in hepatectomy. Considering the lack of high quality original studies, prospective clinical trials should be conducted to provide strong evidence for clinical guidelines formation, and the insurance coverage policies should be established to promote the application of robotic surgery in the future.

BACKGROUND: Clinical practice guidelines (CPGs) play an important role in healthcare in China as well as in the world. However, the current status and trends of Chinese CPGs are unknown. The aim of this study was to systematically review the present situation and the quality of Chinese CPGs published in the peer-reviewed medical literature. METHODS: To identify Chinese CPGs, a systematic search of relevant literature databases (CBM, WANFANG, VIP, and CNKI) was performed for the period January 1978 to December 2010. We used the AGREE II instrument to assess the quality of the included guidelines. RESULTS: We evaluated 269 guidelines published in 115 medical journals from 1993 to 2010 and produced by 256 different developers. Only four guidelines (1%) described the systematic methods for searching and selecting the evidence, 14 (5%) guidelines indicated an explicit link between the supporting evidence and the recommendations, only one guideline used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Thirty-one guidelines (12%) mentioned updates and the average frequency of update was 5.5 years; none described a procedure for updating the guideline. From the assessment with the Appraisal of Guidelines for Research and Ecaluation II (AGREE II), the mean scores were low for the domains "scope and purpose" (19%) and "clarity of presentation" (26%) and very low for the other domains ("rigour of development" 7%, "stakeholder involvement" 8%, "applicability" 6% and "editorial independence" 2%). CONCLUSIONS: Compared with other studies on the quality of guidelines assessed with the AGREE instrument in other countries, Chinese CPGs received lower scores, which indicates a relatively poor quality of the guidelines. However, there was some increase over time.

OBJECTIVE: To investigate clinical significance and application of modified pelvic floor reconstruction developed by Peking Union Medical College Hospital (MPFR) in treatment of severe pelvic organ prolapse (POP) by comparing the effectiveness, quality of postoperative sexual life, life satisfaction and risk factors for POP recurrence with the following two surgical procedures: traditional total vaginal hysterectomy with anterior-posterior colporrhaphy (TVH-APC) and total vaginal hysterectomy with lateral colporrhaphy and sacrospinous ligament fixation and vaginal bridge repair and episiotomy (TVH-LC-SSLF-VBR-EP). METHODS: Totally 173 patients with severe POP and at least two compartments defects of pelvic floor underwent surgeries in the study, 86 patients (group A) were treated by MPFR with polypropylene mesh application, 58 (group B) were treated by TVH-APC, and 29 patients (group C) were treated by TVH-LC-SSLF-VBR-EP. Peri-operative data and outcomes of postoperative courses at 6, 12, 18 months were collected and analyzed, in the meantime, the risk factors of recurrence were studied. RESULTS: (1) No statistical difference was observed among the above 3 groups in terms of length of operation, amount of blood loss, length of hospital stay, and morbidity after surgery (P > 0.05). (2) Cost hospitalization was (11 448 ± 3049) Yuan in group A, which was significantly higher than (7262 ± 1607) Yuan in group B and (7140 ± 1817) Yuan in group C (P < 0.05). (3) The length of vaginal cuff of (7.5 ± 1.4) cm in group A and (5.6 ± 1.1) cm in group C were significantly longer than (7.1 ± 0.6) cm in group B (P < 0.05). The width of vaginal cuff of (4.3 ± 0.3) cm in group A was larger than (3.4 ± 0.3) cm in group B and (3.3 ± 0.4) cm in group C (P < 0.05). (4) The recurrence rate at 12 months after surgery was 12.8% (11/86) in group A, which was similar with 17.2% (5/29) in group C (P > 0.05) and significantly less than 36.2% (21/58) in group B (P < 0.05). The rate of active sexual life of 16.3% (14/86) in group A was significantly higher than 1.7% (1/58) in group B and 0 in group C (P < 0.05). The index of life quality improvement at 12 months after surgery was 48 ± 12 in group A, which was no less than 53 ± 16 in group C (P > 0.05) and higher than 27 ± 9 in group B (P < 0.05). (5) Mesh rejection was observed in 6 patients in group A within 3 months after surgery, while the posterior vaginal wall was exclusively involved. No difference was found in urinary retention or urinary incontinence among three groups (P > 0.05). (6) The severe degree of POP, type of surgical procedure (TVT-APC), anterior compartment defect of pelvic floor, and early days of performing pelvic floor reconstruction surgeries were high risk factors for POP recurrence (P < 0.05). CONCLUSIONS: MPFR has a better curative effect and lower recurrence rate on patients with POP. It can help patients regain integrity of anatomical structure and functions of pelvic floor. TVH-LC-SSLF-VBR-EP is also effective.

OBJECTIVE: To evaluate clinical application of improved percutaneous tracheostomy with dilatational technique. METHODS: In 55 patients an improved percutaneous tracheostomy was used, and in another 52 patients an old technique of percutaneous tracheostomy was used. RESULTS: The cost of the improved percutaneous tracheostomy was only (216.0+/-4.4) yuan, operation time was (5.0+/-3.5) minutes, while the cost of the old method was (3 011.0+/-5.3) yuan, and operation time was (10.0+/-6.9) minutes. The difference between them was significant (t=23.60, 4.76, both P<0.001), but there were no differences in the time of bleeding and healing (both P>0.05). CONCLUSION: The improved percutaneous tracheostomy was more expeditious, costless, better healing, scar smaller. Therefore, it is useful in emergency care, and it can take the place of classical tracheostomy.
