Introduction: Chronic liver damage from methotrexate (MTX) is not uncommon, and fatal outcome is rare. We experienced a case of hepatic failure leading to death. We considered the cause of death through this case and proposed a method to prevent the progression of this liver injury. Patient concerns: We report the case of a patient with rheumatoid arthritis treated with MTX for 15 years. Diagnosis, interventions, and outcomes: A liver biopsy revealed histological changes similar to those of advanced nonalcoholic steatohepatitis (NASH), most likely induced by MTX. MTX was discontinued after 4 years. Two years after the discontinuation, the patient died of irreversible hepatic failure. Her obesity, complicated by type 2 diabetes mellitus, might have aggravated MTX-induced NASH-like liver injury. Conclusion: Early diagnosis and immediate MTX discontinuation following NASH diagnosis and strict type 2 diabetes mellitus control might have prevented the irreversible progression of liver injury.

Multimodal molecular imaging technologies have been widely used to optimize medical research and clinical practice. Bibliometric analysis was performed to identify global research trends, hot spots, and scientific frontiers of multimodal molecular imaging technology from 2012 to 2021. The articles and reviews related to multimodal molecular imaging were retrieved from the Web of Science Core Collection. A bibliometric study was performed using CiteSpace and VOSviewer. A total of 4169 articles and reviews from 2012 to 2021 were analyzed. An increasing trend in the number of articles on multimodal molecular imaging technology was observed. These publications mainly come from 417 institutions in 92 countries, led by the USA and China. K. Bailey Freund published the most papers amongst the publications, while R.F. Spaide had the most co-citations. A dual map overlay of the literature shows that most publications were specialized in physics/materials/chemistry, and molecular/biology/immunology. Synergistic therapy in cancer, advanced nanotechnology, and multimodal imaging in ophthalmology are new trends and developing areas of interest. A global bibliometric and visualization analysis was used to comprehensively review the published research related to multimodal molecular imaging. This study may help in understanding the dynamic patterns of multimodal molecular imaging technology research and point out the developing areas of this field.

This cross-sectional analysis aimed to assess the extent of conflicts of interest among the Japanese government coronavirus disease 2019 (COVID-19) advisory board members and elucidate the accuracy of conflicts of interest (COI) disclosure and management strategies. Using the payment data from all 79 pharmaceutical companies in Japan between 2017 and 2019 and direct research grants from the Japanese government between 2019 and 2020, we evaluated the extent of financial and non-financial COI among all 20 Japanese government COVID-19 advisory board members. The Ethic Committee of the Medical Governance Research Institute approved this study. Japanese government COVID-19 advisory board members were predominantly male (75.0%) and physicians (50.0%). Between 2019 and 2020, 2 members (10.0%) received a total of $819,244 in government research funding. Another 5 members (25.0%) received $532,127 in payments, including $276,722 in personal fees, from 31 pharmaceutical companies between 2017 and 2019. The average value of the pharmaceutical payments was $9155 (standard deviation: $12,975). Furthermore, neither the Ministry of Health, Labor, and Welfare nor the Japanese Cabinet Secretariat disclosed financial or non-financial COI with industry. Additionally, the government had no policies for managing COI among advisory board members. This study found that the Japanese government COVID-19 advisory board had financial and non-financial COI with pharmaceutical companies and the government. Furthermore, personal communication received as part of this research indicated that there were no rigorous COI management strategies for the COVID-19 advisory board members. Any government must ensure the independence of scientific advisory boards by implementing more rigorous and transparent management strategies that require the declaration and public disclosure of all COI.

Rationale: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are commonly used in the treatment of advanced non-small cell lung cancer. However, patients will inevitably develop resistance to EGFR-TKIs in the long-term treatment process. In this paper, we report a case of small cell lung cancer transformation after EGFR-TKIs treatment in lung adenocarcinoma. We summarize the characteristics of this case and the treatment after transformation, and emphasized the repeat biopsy and dynamic monitoring its genetic mutation was necessary. Patient concerns: A 75-years-old man with no smoking history was admitted to our hospital with repeated cough and expectoration for 1 month and chest enhancement computed tomography showed paracbronchial soft tissue mass in the lower lobe of the left lung, which was considered to be central lung cancer. Diagnoses: The first pathological analysis of lung biopsy confirmed left lung adenocarcinoma and clinical stage was T3N3M1 IVA. In June 2021, the second bronchoscopic biopsy was performed, and pathology showed small cell neuroendocrine carcinoma in the left lung. Interventions: Gefitinib was given to patients when the first next generation sequence test showed EGFR L858 mutation. When the second next generation sequence test revealed EGFR T790M mutation, the patient received with osimertinib. The patient got 2 cycles chemotherapy of etoposide plus netaplatin when diagnosed with small cell lung cancer. Outcomes: Progression-free survival was only 8 months after gefitinib treatment. Moreover, the patient was insensitive to Oxitinib, and the disease progressed after 2 months of treatment with Oxitinib. Finally, he died of severe infection and hepatic failure after a diagnosis of small cell lung cancer. Lessons: Our case highlights that if a patient has rapid disease progression, increase of serum neuron-specific enolase, and TP53 and Rb1 inactivation during EGFR-TKIs treatment, we should be alert to the pathological type transformation to small cell lung cancer.

During medial patellofemoral ligament (MPFL) reconstruction, fluoroscopic determination of the femoral tunnel point is the most common method. However, there is a decrease in tunnel position accuracy due to rotation of the femur during fluoroscopy, as well as the damage to the operator from multiple fluoroscopies, whereas the 3D-printed individualized navigation template is not affected by this factor. This study focuses on the accuracy and early clinical efficacy of 2 different ways to determine the femoral tunnel (Schöttle point) for double-bundle isometric MPFL reconstruction. This is a retrospective study, conducted between 2016 and 2019, in which 60 patients with recurrent patellar dislocation were divided into 2 groups: 30 with MPFL reconstruction at the Schöttle point determined by 3D-printed individualized navigation template (group A) and 30 with MPFL reconstruction at the Schöttle point determined by fluoroscopic guidance (group B). The changes in patella congruence angle and patella tilt angle before and after surgery were assessed using computed tomography scans of the knee, knee function was assessed using the Kujala knee score and the international knee documentation committee (IKDC) score, and the 2 approaches were compared for the intraoperative establishment of the femoral tunnel position at a distance from Schöttle point. At a minimum of 3 years follow-up, patella tilt angle and patella congruence angle returned to normal levels and were statistically different from the preoperative range, with no significant differences between the 2 groups at the same period, and Kujala and IKDC scores of knee function were significantly improved in both groups after surgery. The mean Kujala and IKDC scores were statistically different between groups A and B at 3 and 6 months postoperatively. No statistically significant differences were seen between the 2 groups at the final follow-up. Both femoral tunnel localization approaches for double-bundle isometric MPFL reconstruction resulted in good knee function. At no < 3 years of follow-up, the use of a 3D-printed individualized navigation template did result in more accurate isometric points and higher knee function scores in the early postoperative period.

Rationale: Venovenous extracorporeal membrane oxygenation (ECMO) is recommended for the treatment of critically ill patients with acute respiratory distress syndrome due to coronavirus disease 2019 (COVID-19). However, ECMO management can cause both bleeding and thrombotic complications. There are insufficient coagulofibrinolytic data for appropriate ECMO management in patients with COVID-19. Patient concerns: A 48-year-old man with severe COVID-19-acute respiratory distress syndrome underwent long-term venovenous ECMO management for 48 days. Refractory oronasal bleeding developed on day 13, so the administration of unfractionated heparin was ceased for 29 days. Diagnosis: The patient showed dynamic coagulofibrinolytic responses associated with ECMO management, as shown by fibrin/fibrinogen degradation products, soluble fibrin, thrombin-antithrombin complex, and plasmin-α2-plasmin inhibitor complex elevations, suggesting the development of ECMO-induced coagulopathy. Interventions: We assessed coagulofibrinolytic markers to decide the appropriate timing for controlling excessive activation of coagulation by exchanging ECMO circuits. Moreover, viscoelastic hemostatic assays were used for adequate transfusion of blood products. Outcomes: Safe long-term ECMO management was completed, which was withdrawn on day 48. The patient was weaned off mechanical ventilation on day 57 and was transferred to another hospital for rehabilitation. Lessons: Monitoring the coagulofibrinolytic status using markers and viscoelastic hemostatic assays may be effective for safe long-term ECMO management even without anticoagulant therapy.

Urinary incontinence (UI), which affects the quality of life, is associated with different risk factors during pregnancy. We aimed to study the risk factors related to UI during pregnancy among nulliparous women in the UAE. This is a prospective descriptive survey, which included all nulliparous women after the first 24 weeks’ gestation from 2012 to 2014 in a teaching hospital in the UAE. Participants were interviewed face-to-face, using a structured and pre-tested questionnaire and divided into 2 groups: those with UI and those without it. Factors which were statistically significant (P < .05) between the 2 groups were entered into an logistic regression backward logistic regression model to define the factors predicting UI. Five hundred one participants were interviewed. UI occurred in 106/501 (21.2%). The 2-sample comparison analysis showed that urinary tract infection (UTI) (47.2% vs 34.4%, P = .018) and its number of attacks (P = .007), chronic cough (28.3% vs 13.9%, P < .001) and chronic constipation (34.9% vs 19%, P < .001) were statistically significant between those who had UI and those who did not. The logistic regression backward logistic regression model showed that the risk factors which predicted UI were chronic constipation (P = .003), chronic cough (P = .008), and the number of UTI attacks (P = .036). UI affects one-fifth of nulliparous women in the UAE. Chronic cough, constipation, and repeated UTI infection, significantly increase the odds of UI during pregnancy. Addressing these risk factors may reduce the risk of UI.

Objectives: The intestinal flora is closely related to the pathogenesis of nonalcoholic fatty liver disease (NAFLD). This study intends to systematically evaluate the efficacy and safety of probiotics in the treatment of NAFLD through a meta-analysis of published randomized controlled trials. Methods: This study was conducted through a search of published randomized controlled trials using probiotic-related drugs for the treatment of nonalcoholic fatty liver disease (up to April 6, 2022). The JADAD evaluation table was used to evaluate the quality of the literatures included in the search, and the risk of bias was evaluated according to the Cochrane evaluation manual. Finally, RevMan5.4 software was used for meta-analysis. Results: A total of 21 randomized clinical trials involving 1037 patients with NAFLD were included in this study. Meta-analysis results showed that after probiotic intervention, liver function, blood lipid level, blood glucose levels and insulin levels were significantly reduced, which had a good effect on improving hepatic steatosis. However, it did not significantly improve BMI, inflammatory factors, or homeostasis model assessment of insulin resistance. Through the subgroup analysis of the course of treatment, it was found that ALT, GGT, TG, and blood sugar improved better in the probiotic treatment course of greater than or equal to 12 weeks. Conclusion: This study shows that the use of probiotics therapy has a good regulating effect on liver function, steatosis, blood glucose level, insulin level and blood lipid level in NAFLD patients.

Denosumab is a human monoclonal antibody that targets nuclear factor-kappa B ligand and is highly effective in blocking bone resorption. Bibliometrics can intuitively show the research development process, research status, research hotspots and development trend of a certain topic for researchers. This study assessed the course of research and development for denosumab in terms of publications over the past 2 decades. Web of Science databases were searched to identify publications related to research on denosumab from January 1, 2005 to December 31, 2022. The VOS Viewer software (version 1.6.17) and Bibliometrix package in R (version 4.1.3) were used in this study. There were 5119 denosumab-related publications during this period. The total number of citations of denosumab-related publications reached 94917. The most articles were published in the field of Endocrinology Metabolism. As an international language, English remains the most popular language for writing papers. Five of the top ten institutions originated in the USA. Through the VOS Viewer analysis, we found that the relationships between Amgen Inc. with its collaborations were grouped into 4 clusters, the USA was the mainland for research and development on denosumab, closely collaborating with many other countries, such as Canada, Japan, England, and China. Wagman RB from USA was the most prolific author with 119 publications. The journal with the most publications was Osteoporosis International (481 publications). The most cited article was “Denosumab for Prevention of Fractures in Postmenopausal Women with Osteoporosis” with 2053 citations. The clinical trial comprised 6 of the 10 most frequently cited publications, and the rest consisted of reviews. The most frequent keywords for publications since January 1, 2014 were “prevention” and “management,” indicating that a number of prevention and management measures have been developed to regulate the use of denosumab in treating osteoporosis. Our research provided a comprehensive review of denosumab-related publications, suggesting that the development of denosumab is a long process and numerous clinical trials have been conducted before applications in clinical settings.

Background: Virtual reality (VR) is an interesting and promising way to teach cardiopulmonary resuscitation (CPR) to adult laypersons as its high immersive characteristics could improve the level of skills and acquired knowledge in learning basic life support (BLS). Methods: This systematic review assesses current literature about BLS training with VR and its possible effect on CPR-quality parameters, self-efficacy, perceived learning, and learners’ satisfaction and short and long-term patients’ outcome. We screened the Cochrane Library, PubMed, CINAHL, MEDLINE Ovid, Web of Science, and Scopus databases and included only clinical trials and quasi-experimental studies published from inception to October 1, 2021, which analyzed adult laypersons’ BLS training with the use of VR. Primary outcomes were CPR parameters (chest compression rate and depth, Automated External Defibrillator use). Secondary outcomes were self-efficacy, perceived learning and learners satisfaction, and patients’ outcomes (survival and good neurologic status). The risk of bias of included study was assessed using the Cochrane Handbook for Systematic Reviews of Interventions tool to evaluate randomized control trials and the transparent reporting of evaluations with nonrandomized designs checklist for nonrandomized studies. Results: After full article screening, 6 studies were included in the systematic review (731 participants) published between 2017 and 2021. Because of the heterogeneity of the studies, we focused on describing the studies rather than meta-analysis. The assessment of the quality of evidence revealed overall a very low quality. Training with VR significantly improved the rate and depth of chest compressions in 4 out of 6 articles. VR was described as an efficient teaching method, exerting a positive effect on self-efficacy, perception of confidence, and competence in 2 articles. Conclusion: VR in BLS training improves manual skills and self-efficacy of adult laypersons and may be a good teaching method in a blended learning CPR training strategy. VR may add another way to divide complex parts of resuscitation training into easier individual skills. However, the conclusion of this review suggests that VR may improve the quality of the chest compressions as compared to instructor-led face-to-face BLS training.
