Evaluation of TikTok videos on acute pancreatitis: content quality and reliability analysis.

BACKGROUND: Acute pancreatitis (AP) is a common acute digestive system disorder, with patients often turning to TikTok for AP-related information. However, the platform's video quality on AP has not been thoroughly investigated. OBJECTIVE: The main purpose of this study is to evaluate the quality of videos about AP on TikTok, and the secondary purpose is to study the related factors of video quality. METHODS: This study involved retrieving AP-related videos from TikTok, determining, and analyzing them based on predefined inclusion and exclusion criteria. Relevant data were extracted and compiled for evaluation. Video quality was scored using the DISCERN instrument and the Health on the Net (HONcode) score, complemented by introducing the Acute Pancreatitis Content Score (APCS). Pearson correlation analysis was used to assess the correlation between video quality scores and user engagement metrics such as likes, comments, favorites, retweets, and video duration. RESULTS: A total of 111 TikTok videos were included for analysis, and video publishers were composed of physicians (89.18%), news media organizations (13.51%), individual users (5.41%), and medical institutions (0.9%). The majority of videos focused on AP-related educational content (64.87%), followed by physicians' diagnostic and treatment records (15.32%), and personal experiences (19.81%). The mean scores for DISCERN, HONcode, and APCS were 33.05 ± 7.87, 3.09 ± 0.93, and 1.86 ± 1.30, respectively. The highest video scores were those posted by physicians (35.17 ± 7.02 for DISCERN, 3.31 ± 0.56 for HONcode, and 1.94 ± 1.34 for APCS, respectively). According to the APCS, the main contents focused on etiology (n = 55, 49.5%) and clinical presentations (n = 36, 32.4%), followed by treatment (n = 24, 21.6%), severity (n = 20, 18.0%), prevention (n = 19, 17.1%), pathophysiology (n = 17, 15.3%), definitions (n = 13, 11.7%), examinations (n = 10, 9%), and other related content. There was no correlation between the scores of the three evaluation tools and the number of followers, likes, comments, favorites, and retweets of the video. However, DISCERN (r = 0.309) and APCS (r = 0.407) showed a significant positive correlation with video duration, while HONcode showed no correlation with the duration of the video. CONCLUSIONS: The general quality of TikTok videos related to AP is poor; however, the content posted by medical professionals shows relatively higher quality, predominantly focusing on clinical presentations and etiologies. There is a discernible correlation between video duration and quality ratings, indicating that a combined approach incorporating the guideline can comprehensively evaluate AP-related content on TikTok.

Laparoscopic Anatomical Cranial Sub-segmentectomy of Segment VII (S7) with Super-Selective Intra-arterial Nano-ICG Positive Staining-Guided Trans-Parenchymal Approach.

BACKGROUND: With introduction of "cone unit," which is the smallest resectable anatomical area supplied by a tertiary branch of Glissonean pedicle, more precise subsegmental anatomical resection has been proposed.1 Super-selective intra-arterial ICG staining, delivering ICG and lipiodol mixing to arterial branch using interventional radiology, has been proved feasibility especially for complicated anatomy.2-6 It was difficult to uniformly mix water-soluble ICG with lipophilic lipiodol, rendering to inconsistency development of liver segment between angiography and laparoscopy. Nano-ICG is a uniform mixing of ICG and lipiodol.7 We demonstrated an exclusive "two-step" method to perform LAR for cranial S7 via super-selective intra-arterial nano-ICG staining guidance. METHODS: A 70-year-old male was admitted. CT scan showed tumor was located in cranial S7 with 2.1*1.9 cm. Preoperative AFP was 4.66 ng/ml and PIVKA-II was 2332 mAU/ml. The liver function was Child-Pugh class A and ICG-15R was 7.8%. Given that tumor was confined to cranial S7, precise anatomical sub-segmentectomy was warranted. This study was approved by the West China Hospital, Sichuan University Ethics Committee (approval number: 2023-2327). RESULTS: The operation was performed "two step." "First step" was super-selective intra-arterial nano-ICG embolization in intervention room, while "second step" was performed in operation room. ICG demarcation line was clearly identified even after 7 hr. After full mobilization of right hemiliver, we performed transparenchymal approach to find and clamp pedicle of cranial S7 under fluorescence guidance. Operation time was 150 min with 20 ml of blood loss with uneventful course. CONCLUSIONS: Although LAR of S7 remains challenging, super-selective intra-arterial nano-ICG positive staining guidance might be a feasible and safe option.

Screening for negative emotions and analysis of related factors among general surgery inpatients: a retrospective cross-sectional study.

Background: Adverse psychological states in surgical patients can impact outcomes. This study aimed to evaluate mood disorders and associated factors in general surgery inpatients using the Huaxi Emotional Distress Index (HEI). Methods: This retrospective cross-sectional study analyzed HEI scores of 20,398 adult patients hospitalized for elective surgery at a tertiary hospital in China (2018-2021). Univariable and multivariable logistic regression identified factors linked to moderate/severe mood disturbances. Results: Factors linked to moderate/severe mood disturbances were identified through univariable and multivariable logistic regression. The results showed that 3.7% of the patients had HEI ≥ 13, indicating significant emotional issues. The mean age was 52.67 (16.14) years in the group with no/mild distress and 59.65 (16.34) years in the group with moderate/severe distress. Among all the cases included, there were 2,689 cases (13.18%) of gastric and esophageal diseases, 1,437 cases (7.04%) of hepatic diseases, 913 cases (4.47%) of periampullary and pancreatic tumors, 9,150 cases (44.85%) of gallbladder diseases, 2,777 cases (13.61%) of colorectal diseases, and 3,432 cases (16.83%) of other diseases. The male percentage was 45.5 and 54.9% in the two groups, respectively. Older age, male gender, unstable occupations, lower education, and unmarried status were associated with higher risks of mood disturbances (all p < 0.05). A significant downward trend in adverse emotions was observed with increasing education levels (p < 0.001). Furthermore, the study found that the inpatients had higher HEI scores prior to the COVID-19 pandemic compared to during the pandemic (p < 0.001). However, the occurrence of adverse mood states in these patients was not exacerbated by the COVID-19 pandemic. The trend test remained highly significant in the none-adjusted, age-sex adjusted, and fully adjusted models (all p for trend <0.001). Conclusion: The implementation of routine screening in higher education institutions (HEIs) allows for the early identification of surgical inpatients who require psychological intervention. It is recommended that counseling services focus on individuals with lower levels of education and income instability in order to address negative mood states. Furthermore, the potential application of this screening system in other clinical settings could enable earlier psychological interventions for a larger number of patients.

Neoteric Semiembedded ß-Tricalcium Phosphate Promotes Osteogenic Differentiation of Mesenchymal Stem Cells under Cyclic Stretch.

ß-Tricalcium phosphate (ß-TCP) is a bioactive material for bone regeneration, but its brittleness limits its use as a standalone scaffold. Therefore, continuous efforts are necessary to effectively integrate ß-TCP into polymers, facilitating a sturdy ion exchange for cell regulation. Herein, a novel semiembedded technique was utilized to anchor ß-TCP nanoparticles onto the surface of the elastic polymer, followed by hydrophilic modification with the polymerization of dopamine. Cell adhesion and osteogenic differentiation of mesenchymal stem cells (MSCs) under static and dynamic uniaxial cyclic stretching conditions were investigated. The results showed that the new strategy was effective in promoting cell adhesion, proliferation, and osteogenic induction by the sustained release of Ca2+ in the vicinity and creating a reasonable roughness. Specifically, released Ca2+ from ß-TCP could activate the calcium signaling pathway, which further upregulated calmodulin and calcium/calmodulin-dependent protein kinase II genes in MSCs. Meanwhile, the roughness of the membrane and the uniaxial cyclic stretching activated the PIEZO1 signaling pathway. Chemical and mechanical stimulation promotes osteogenic differentiation and increases the expression of related genes 2-8-fold. These findings demonstrated that the neoteric semiembedded structure was a promising strategy in controlling both chemical and mechanical factors of biomaterials for cell regulation.

Preliminary exploration of hepatic parenchymal near-infrared fluorescence imaging technique via retrograde biliary approach: a feasibility study (with video).

This paper explores the feasibility and principle of hepatic parenteral fluorescence imaging technology after retrograde injection of indocyanine green (ICG) through endoscopic nasobiliary drainage (ENBD). The data were collected from 53 patients with cholecystolithiasis and choledocholithiasis, from October 2022 to March 2023, diagnosed by fluorescence imaging technique retrograde biliary approach (FIT-RB). We divided the patients into two groups according to the features of liver parenchyma, the poor group (n = 34, including scattered or no imaging) and the good group (n = 19, regular uniform imaging). We compared and analyzed the perioperative results of the two groups and explored the influencing factors of the success of FIT-RB and the ICG concentration suitable for this imaging technique. The good imaging rate of the 53 enrolled cases was 35.8%. The bilirubin level before ENBD and laparoscopic cholecystectomy in the poor group was significantly higher than that in the good group (P < 0.001). The proportion of higher ICG concentrations (0.5 mg/mL) was significantly higher in the good group (P = 0.028). Our results demonstrated that the success rate of good imaging was 4.53 times higher than that of low-dose ICG (0.125 or 0.25 mg/L) cases at 0.5 mg/ml of ICG. The level of total bilirubin and direct bilirubin were negatively correlated with the imaging effect, and total bilirubin and direct bilirubin levels were important predictors of the efficacy of FIT-RB. FIT-RB is safe and feasible in patients with low site bilirubin levels. An ICG concentration of 0.5 mg/ml may be ideal for implementing this technique.

GC/MS and LC/MS serum metabolomic analysis of Chinese LN patients.

China, being a densely populated nation, faces a substantial economic burden due to a high incidence of lupus nephritis (LN) cases. The concealed onset of LN has resulted in many individuals have missed the optimal timing for treatment. The aim of the research is to study the serum metabolomics of Chinese LN patients using gas chromatography (GC)/mass spectrometry (MS) and liquid chromatography (LC)/MS to identify potential diagnostic markers. Fifty LN patients and fifty normal controls, matched for Body Mass Index (BMI) and age, were selected. Serum analysis was conducted using GC/MS and LC/MS, followed by multivariate statistical analysis. Various multidimensional analyses, including principal component analysis, partial least squares discrimination analysis, and orthogonal partial least squares discrimination analysis, along with one-dimensional analyses such as t-tests, were performed. Metabolites with variable importance in projection value > 1 and a p-value < 0.05 were considered critical biomarkers for LN. Furthermore, identified biomarkers delineated relevant metabolic pathways, and a metabolic pathway map was obtained from the database. Forty-one metabolites were identified as potential LN biomarkers, primarily associated with immune regulation, energy metabolism, intestinal microbial metabolism, renal damage, and oxidative stress. The potential for diagnosing LN and other diseases through metabolomics is demonstrated. Future research should explore larger sample sizes, metabolomic comparisons across different diseases and health states, and integration of metabolomics with clinical diagnostics. Such studies will enhance the understanding of metabolomics in medical diagnosis and provide robust support for its practical application.

Comparison of short-term outcomes between robotic and laparoscopic liver resection: a meta-analysis of propensity score-matched studies.

OBJECTIVE: This meta-analysis aimed to compare short-term outcomes between robotic liver resection (RLR) and laparoscopic liver resection (LLR) using data collected from propensity score-matched studies. METHODS: The PubMed, Cochrane Library, and Embase databases were searched to collect propensity score-matched studies comparing RLR and LLR. Relevant data were extracted and analyzed. Odds ratios (ORs) and standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated using fixed-effect or random-effect models. Meta-regression analysis was performed for primary outcome measures. Subgroup analyses and sensitivity analyses were performed for outcomes exhibiting high heterogeneity. Quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation framework. RESULTS: Twenty-two propensity score-matched studies were included to comprise 5272 patients (RLR group, 2422 cases; LLR group, 2850 cases). Intraoperative blood loss (SMD=-0.31 ml, 95% CI -0.48 to -0.14; P =0.0005), open conversion (OR=0.46, 95% CI 0.37-0.58; P <0.0001), and severe complications (OR=0.76, 95% CI 0.61-0.95; P =0.02) were significantly lower in the RLR group. Operation time, odds of use, and duration of Pringle maneuver, length of hospital stay, and odds of intraoperative blood transfusion, overall complications, R0 resection, reoperation, 30-day readmission, 30-day mortality, and 90-day mortality did not significantly differ between the groups. Further subgroup and sensitivity analyses suggested that the results were stable. Meta-regression analysis did not suggest a correlation between primary outcomes and study characteristics. The quality of evidence for the primary outcomes was medium or low, while that for the secondary outcomes was medium, low, or very low. CONCLUSION: Although some short-term outcomes are similar between RLR and LLR, RLR is superior in terms of less blood loss and lower odds of open conversion and severe complications. In the future, RLR may become a safe and effective replacement for LLR.

Transhepatic arterial approaches for ICG injection to guide laparoscopic anatomical hepatectomy: A case series study.

BACKGROUND: Laparoscopic anatomical hepatectomy guided by near-infrared fluorescence imaging (NIR-FI) has been utilized extensively. However, it is difficult to resect "cone units" above the third branch of the Glissonean pedicle in the right posterior lobe using the laparoscopic positive or negative staining techniques. Therefore, we undertook a new laparoscopic segmentectomy based on the concept of "cone unit" assisted by interventional radiology combined with NIR-FI. METHODS: Laparoscopic segmentectomy guided by NIR-FI via super-selective hepatic arteriography and trans-arterial injection of ICG was carried out on 13 patients with early-stage HCC between September 2020 and January 2022.11 of cases were successful, and relevant pathological characteristics and perioperative outcomes were retrospectively analyzed. RESULTS: Two cases failed NIR-FI out of which one case involved over-staining to the non-target segment, and in the other case, which was to undergo laparoscopic segment V resection, only the ventral segment was stained while the imaging of the dorsal segment failed. In the intraoperative conditions, the tumor safe margin was 1.1 (0.7-1.55) cm, the interventional operation time was 50 (45.5-60.5) minutes, the operation time was 280 (242.5-307.5) minutes, the blood loss was 100 (50-200) ml, the postoperative hospital stay was 5 (4.5-5.5) days. No cases converted to laparotomy, and no serious postoperative complications developed. CONCLUSIONS: NIR-FI through super-selective hepatic arteriography and trans-arterial injection of ICG can provide a clear and lasting navigation aid for laparoscopic segmentectomy, which may have positive implication for early-stage HCC with poor preoperative liver reserves.

Laparoscopic cholecystectomy assisted by combined intravenous and intracholecystic fluorescent cholangiography: a case report.

This case report describes a laparoscopic approach using fluorescence imaging guidance to treat gangrenous cholecystitis with perforation (GCP). A male patient in his early 60s presented with 3 days of right upper abdominal pain. Computed tomography and ultrasonography findings were consistent with a stone incarcerated in the gallbladder neck, GCP, and localized peritonitis. Percutaneous gallbladder drainage was initially performed, followed by laparoscopic cholecystectomy 7 days later, using combined intravenous and intracholecystic fluorescent cholangiography. This technique allowed visualization of the cystic and common bile ducts during surgery and enabled safe removal of the diseased gallbladder. The patient recovered well without complications, and reported no pain or discomfort at a 2-month follow-up.

Safety and efficacy of laparoscopic transperitoneal versus retroperitoneal resection for benign retroperitoneal tumors: a retrospective cohort study.

BACKGROUND AND OBJECTIVE: Benign retroperitoneal tumors (BRTs) are clinically rare solid tumors. This study aimed to compare the safety and efficacy of laparoscopic transperitoneal versus retroperitoneal resection for BRTs. METHODS: The clinical data of 43 patients who had pathologically confirmed BRTs and underwent laparoscopic resection in a single center from January 2019 to May 2022 were retrospectively analyzed. Patients were divided into two groups according to the surgical methods: the Transperitoneal approach group (n = 24) and the Retroperitoneal approach group (n = 19). The clinical characteristics and perioperative data between the two groups were compared. The baseline data and surgical variables were analyzed to determine the impact of different surgical approaches on the treatment outcomes of BRTs. RESULTS: No significant difference was observed between the two groups in gender, age, body mass index, the American Society of Anesthesiologists score, presence of underlying diseases, tumor size, tumor position, operation duration, intraoperative hemorrhage, postoperative hospital stay, intestinal function recovery time, and postoperative complication rate. The conversion rate from laparoscopic to open surgery was significantly lower in the Transperitoneal approach group than in the Retroperitoneal approach group (1/24 vs. 5/19, χ2 = 4.333, P = 0.037). Tumor size was an independent influencing factor for the effect of surgery (odds ratio = 1.869, 95% confidence interval = 1.135-3.078, P = 0.014) and had a larger efficacy on the retroperitoneal group (odds ratio = 3.740, 95% confidence interval = 1.044-13.394, P = 0.043). CONCLUSION: The laparoscopic transperitoneal approach has the inherent advantages of anatomical hierarchies and surgical space, providing a better optical perspective of the targeted mass and improved bleeding control. This approach may have better efficacy than the retroperitoneal approach, especially in cases of a large tumor or when the tumor is located near important blood vessels.

Liver transplantation versus resection for patients with combined hepatocellular cholangiocarcinoma: A retrospective cohort study.

Background: Combined hepatocellular cholangiocarcinoma (CHC) is a rare primary liver cancer, and whether liver transplantation should be implemented among CHC patients is still controversial. We intend to conduct a retrospective cohort study based on the Surveillance, Epidemiology, and End Results (SEER) database to investigate the prognosis of liver transplantation vs. liver resection among CHC patients. Methods: Patients diagnosed with CHC (ICD-O-3:8180/3) and treated with transplantation or hepatectomy were extracted from the SEER database (2000-2018). We utilized Propensity Score Matching to control confounding bias. Kaplan-Meier curve was used for survival analysis, and Cox regression was used to find independent factors associated with prognosis. Results: We identified 123 (transplantation: 49; resection: 74) patients with CHC who were treated between 2004 and 2015. In the entire cohort, survival analysis demonstrated transplantation group was associated with better overall survival and cancer-specific survival (log-rank p = 0.004 and p = 0.003, respectively). In addition, liver transplantation still conferred better overall and cancer-specific survival than liver resection after Propensity Score Matching (log-rank p = 0.024 and p = 0.048, respectively). However, this advantage didn't appear in the subgroup, regardless of whether the tumor size was greater than 3 cm or not. (≤3 cm: OS log-rank p = 0.230, CSS log-rank p = 0.370; >3 cm: OS log-rank p = 0.110, CSS log-rank p = 0.084). Multivariate analysis validated the finding that liver transplantation was a protective factor for overall survival (HR = 0.55 [0.31-0.95], p = 0.032). Conclusions: Liver transplantation may be an option in individuals with CHC and should be taken into consideration due to its advantages in terms of overall survival and cancer-specific survival. However, a sizable sample is required for future studies to determine which subset of CHC patients may benefit more from liver transplantation.

Resveratrol alleviates MSU-induced gouty arthritis in rats through inhibition of HIF-1α- and NLRP3-derived IL-1ß secretion in macrophages.

Gouty arthritis is an acute and chronic joint inflammatory joint disease characterized by the deposition of monosodium urate (MSU) crystals in joints and periarticular tissues. Resveratrol (3, 5, 4-trihydroxy-trans-stilbene, RV), a natural polyphenolic compound, has anti-inflammatory and antioxidant properties. The purpose of this study was to investigate the effect of resveratrol on rats with gouty arthritis and its molecular mechanism. THP-1-derived macrophages were induced by lipopolysaccharide (LPS) and MSU to create an in vitro gout cell inflammation model, and rats were injected with MSU crystals into the right ankle joint for an in vivo acute gouty arthritis model. We investigated the anti-inflammatory properties of resveratrol using these in vitro and in vitro models. Our findings suggested that resveratrol effectively reduced ankle swelling and synovial inflammation in a dose-dependent manner in rats with acute gouty arthritis, with almost the same effect as colchicine treatment. In MSU-treated THP-1-derived macrophages, resveratrol inhibited NLRP3 inflammasome activation and IL-1ß secretion. Furthermore, resveratrol and the HIF-1α inhibitor PX478 both inhibited the expression of the NLRP3 inflammasome, IL-1ß, and HIF-1α. This study demonstrated that resveratrol significantly improved the symptoms of acute gouty arthritis and its potential mechanism may be IL-1ß reduction via HIF-1α modulation and inhibition of NLRP3 inflammasome activation. Our study might offer a novel sight for the treatment of gouty arthritis.

Surgical indications for solid hepatic benign tumors: An updated literature review.

Hepatic hemangioma, focal nodular hyperplasia, and hepatic adenoma are the most common benign solid liver tumors. However, their surgical indications have been the subject of debate. Minimally invasive liver resection reduces the cost of surgery and may lead to overtreatment of benign liver tumors. Recently, there has been a growing understanding of the etiology, pathogenesis, and natural history of these tumors. Great progress has also been made in imaging. The use of MRI and contrast agents has improved the accuracy of non-invasive diagnosis of these tumors, and especially in the identification of specific molecular subtypes of liver adenoma. These factors have resulted in alterations of surgical indications for these tumors. This article examines recent literature and it discusses the surgical indications for hepatic hemangioma, focal nodular hyperplasia, and hepatic adenoma while summarizing modifications in clinical management.

BACKGROUND: The Chronic Pain Coping Inventory-42(CPCI-42) is mainly used for chronic pain management project, its original version is written in English and has been widely used in western countries. Therefore, the purpose of our study is to apply the CPCI-42 to Chinese patients and evaluate its responsiveness, reliability, and validity for Chinese patients with lumbar disc herniation (LDH). METHODS: Translation and adaptation were carried out in accordance with the guidelines of the American Academy of Orthopedic Surgeons Outcome Committee. A total of 133 patients who were diagnosed with LDH were included in this study. Psychometric evaluations were then performed and included score distribution, internal consistency, test-retest reliability, construct validity, and responsiveness. RESULTS: CPCI-42 is well adapted to the assessment of the cognitive and behavioral strategies of patients with LDH, and the scores of score distribution, internal consistency, test-retest reliability, construct validity, and responsiveness are excellent. Forward and reverse translation of the CPCI-42 to English from Chinese worked smoothly. CONCLUSION: It is applicable to the assessment of quality of life of the cognitive and behavioral strategies of patients with LDH, and the scores of all indicators are excellent.

Translation and Validation of a Simplified Chinese Version of the Anterior Cruciate Ligament-Quality of Life Questionnaire.

Background: The Anterior Cruciate Ligament-Quality of Life (ACL-QOL) questionnaire is a widely used and effective scale for quality of life in patients with chronic anterior cruciate ligament (ACL) injury. Purpose: To translate and adapt the ACL-QOL questionnaire for Chinese patients and evaluate its reliability, validity, and responsiveness in this population. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Translation and adaptation were conducted in accordance with the guidelines of the A merican Academy of Orthopaedic Surgeons Outcome Committee. Included were 121 patients who were diagnosed with a chronic ACL injury and underwent ACL reconstruction between January 2020 and June 2021. Preoperatively, patients completed the simplified Chinese version of the ACL-QOL (ACL-QOL-C), the Knee injury and Osteoarthritis Outcome Score, and the 12-Item Short Form Health Survey. The ACL-QOL-C was also completed at 12- and 24-week follow-ups. Psychometric evaluations were then performed and included score distribution, internal consistency, test-retest reliability, construct validity, and responsiveness. Results: The Cronbach alpha ranged from .905 to .975, indicating excellent internal consistency, and the intraclass correlation coefficient ranged from 0.864 to 0.985, indicating excellent test-retest reliability. The consistency between the above results and our a priori hypotheses was more than 70% (35/42), indicating good construct validity. The standard error of measurement and effect size of the total score and each item of the ACL-QOL-C were >0.8 at the final follow-up, indicating good responsiveness. Conclusion: The English version of the ACL-QOL has been successfully translated into Chinese, and it has been shown to be applicable for the assessment of the quality of life in Chinese patients with chronic ACL injury.
