METHODS: This was an individual participant data meta-analysis for the performance of NITs against liver biopsy for MASH+F2-4, MASH+F2-3 and MASH+F4. Index tests were the FibroScan-AST (FAST) score, liver stiffness measured using vibration-controlled transient elastography (LSM-VCTE), the fibrosis-4 score (FIB-4) and the NAFLD fibrosis score (NFS). Area under the receiver operating characteristics curve (AUROC) and thresholds including those that achieved 34% SFR were reported.
RESULTS: We included 2281 unique cases. The prevalence of MASH+F2-4, MASH+F2-3 and MASH+F4 was 31%, 24% and 7%, respectively. Area under the receiver operating characteristics curves for MASH+F2-4 were .78, .75, .68 and .57 for FAST, LSM-VCTE, FIB-4 and NFS. Area under the receiver operating characteristics curves for MASH+F2-3 were .73, .67, .60, .58 for FAST, LSM-VCTE, FIB-4 and NFS. Area under the receiver operating characteristics curves for MASH+F4 were .79, .84, .81, .76 for FAST, LSM-VCTE, FIB-4 and NFS. The sequential combination of FIB-4 and LSM-VCTE for the detection of MASH+F2-3 with threshold of .7 and 3.48, and 5.9 and 20 kPa achieved SFR of 67% and sensitivity of 60%, detecting 15 true positive cases from a theoretical group of 100 participants at the prevalence of 24%.
CONCLUSIONS: Sequential combinations of NITs do not compromise diagnostic performance and may reduce resource utilisation through the need of fewer LSM-VCTE examinations.
METHODS: A collaboration between the Global Nerve Foundation and Esser Masterclass facilitated the program, which was conducted across three international sites. The curriculum was developed by a panel of experienced peripheral nerve surgeons and included both text-based and multimedia resources. Participants' knowledge and skills were assessed using pre- and postcourse questionnaires.
RESULTS: A total of 73 participants from 26 countries enrolled and consented for data usage for research purposes. The professional background was diverse, including hand surgeons, plastic surgeons, orthopedic surgeons, and neurosurgeons. Participants reported significant improvements in knowledge and skills across all covered topics (p < 0.001). The course received a 100% recommendation rate, and 88% confirmed that it met their educational objectives.
CONCLUSIONS: This study underscores the potential of technology-enabled, collaborative expert-led training programs in overcoming geographical and logistical barriers, setting a new standard for globally accessible, high-quality surgical training. It highlights the practical and logistical challenges of multi-site training, such as time zone differences and participant fatigue. It also provides practical insights for future medical educational endeavors, particularly those that aim to be comprehensive, international, and technologically facilitated.
METHODS: This was an individual participant data meta-analysis of the prognostic performance of histologically assessed fibrosis stage (F0-4), liver stiffness measured by vibration-controlled transient elastography (LSM-VCTE), fibrosis-4 index (FIB-4), and NAFLD fibrosis score (NFS) in patients with NAFLD. The literature was searched for a previously published systematic review on the diagnostic accuracy of imaging and simple non-invasive tests and updated to Jan 12, 2022 for this study. Studies were identified through PubMed/MEDLINE, EMBASE, and CENTRAL, and authors were contacted for individual participant data, including outcome data, with a minimum of 12 months of follow-up. The primary outcome was a composite endpoint of all-cause mortality, hepatocellular carcinoma, liver transplantation, or cirrhosis complications (ie, ascites, variceal bleeding, hepatic encephalopathy, or progression to a MELD score ≥15). We calculated aggregated survival curves for trichotomised groups and compared them using stratified log-rank tests (histology: F0-2 vs F3 vs F4; LSM: <10 vs 10 to <20 vs ≥20 kPa; FIB-4: <1·3 vs 1·3 to ≤2·67 vs >2·67; NFS: 0·676), calculated areas under the time-dependent receiver operating characteristic curves (tAUC), and performed Cox proportional-hazards regression to adjust for confounding. This study was registered with PROSPERO, CRD42022312226.
FINDINGS: Of 65 eligible studies, we included data on 2518 patients with biopsy-proven NAFLD from 25 studies (1126 [44·7%] were female, median age was 54 years [IQR 44-63), and 1161 [46·1%] had type 2 diabetes). After a median follow-up of 57 months [IQR 33-91], the composite endpoint was observed in 145 (5·8%) patients. Stratified log-rank tests showed significant differences between the trichotomised patient groups (p<0·0001 for all comparisons). The tAUC at 5 years were 0·72 (95% CI 0·62-0·81) for histology, 0·76 (0·70-0·83) for LSM-VCTE, 0·74 (0·64-0·82) for FIB-4, and 0·70 (0·63-0·80) for NFS. All index tests were significant predictors of the primary outcome after adjustment for confounders in the Cox regression.
INTERPRETATION: Simple non-invasive tests performed as well as histologically assessed fibrosis in predicting clinical outcomes in patients with NAFLD and could be considered as alternatives to liver biopsy in some cases.

METHODS: This retrospective study was performed at Prince Court Medical Centre, Kuala Lumpur, Malaysia, from January 2020 until June 2021. Ninety-three patients who presented with numbness of fingers, hand, or upper limb; forearm pain; and muscle weakness. They were diagnosed with lacertus syndrome on the basis of local tenderness at the lacertus fibrosus with either weakness of flexor pollicis longus and flexor digitorum profundus of the index finger or paresthesia over the thenar eminence. The patients underwent 3 months of hand therapy, and those with no symptom improvement were offered lacertus release performed by a single surgeon. The surgical technique consists of a surgical incision starting from a point 2 cm distally and 2 cm radially to the medial epicondyle. The incision projects 2 cm distally in an oblique fashion toward the radial styloid. A wide-awake local anesthesia no tourniquet (WALANT) technqiue was utilized and 20 mL of local anesthesic was injected subcutaneously around this region at least 20 minutes before the surgery. Careful dissection was made subcutaneously, and the lacertus fibrosus was identified as a thickened, shiny white structure and released. The Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, grip strength, and pinch strength were tested before and after surgery. At 6 months after surgery, the QuickDASH score was again assessed with a WALANT satisfactory questionnaire.
RESULTS: A total of 93 patients were included in the study. The mean age of the patients was 38.7 years, and most were women (77.4%). The mean operating time was 70 minutes. The mean preoperative QuickDASH score was 53, which significantly reduced immediately after surgery to 7.8 (P < .001) and remained low at 6 months after surgery (10.6). The mean grip strength showed a significant increase from a preoperative mean of 16 kg to a postoperative mean of 24 kg (P < .001). Pinch strength also significantly increased from a preoperative mean of 9 kg to 13 kg after surgery (P < .001).
CONCLUSIONS: Lacertus syndrome remains an underdiagnosed disease that can be treated efficiently with a directed minimal surgical incision under wide-awake local anesthesia. Lacertus release appears to significantly reduce pain and numbness with markedly improved hand grip and pinch strength. The corresponding QuickDASH scores also improved significantly after surgery. This study is vital to our understanding of proximal median nerve entrapment and to accurately diagnose it.
TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.
METHODS: Twenty-four participants were randomly assigned to the therapeutic group (n = 19) (1% lidocaine in 1:100,000 adrenaline) and control group (n = 5) (2% lidocaine alone). Clinical parameters, including skin necrosis, duration of recovery of sensation, and lidocaine toxicity, were monitored. The serum lidocaine level was measured at different time intervals using a high-performance liquid chromatography reagent.
RESULTS: No lidocaine toxicity was recorded in any participant. The therapeutic group had a longer time for recovery of sensation. There was a significant difference in the serum lidocaine levels between both the groups at all time intervals up to 6 hours, with all participants exhibiting serum lidocaine levels below the mild toxicity level of 6.0 μg/mL.
CONCLUSIONS: Lidocaine used within a safe recommended dose in wide-awake local anesthesia no tourniquet for distal radius plating is clinically and biochemically safe.
CLINICAL RELEVANCE: Determining the clinical and biochemical safety profile of lidocaine with adrenaline in wide-awake local anesthesia no tourniquet can promote wider use of this technique.
METHODS: This was a prospective study with patients divided into either the WALANT or GA cohort. The waiting time for surgery, Amsterdam Preoperative Anxiety and Information Scale, blood pressure, and heart rate were measured. Postsurgical questionnaires with the visual analog scale were completed. The surgeon's feedback on the ease of ganglion stalk visibility and usage of diathermy as a measure of a bloodless field was recorded. Patients reported the amount of analgesia consumed and overall satisfaction with the operation via the Surgical Satisfaction-8 questionnaire.
RESULTS: A total of 42 patients underwent wrist ganglion excision in 2 orthopedic centers over a period of 2 years, with 21 undergoing GA and 22 undergoing WALANT. The GA group was more anxious about anesthetic use with a higher demand for information about GA (P = .04). The duration of surgery was significantly shorter in the WALANT group and with a lower diathermy usage (P < .001). There was no difference in terms of surgical difficulty and stalk visualization. The visual analog scale pain score was significantly lower in the WALANT group than in the GA group immediately after surgery (P = .04) and on discharge (P = .004). While at home for 2 weeks, the WALANT group (mean = 2.91 tablets) consumed significantly fewer analgesic tablets than the GA group (mean = 6.25 tablets). However, both groups were satisfied with their experience.
CONCLUSIONS: Wide-awake local anesthesia no tourniquet technique in the excision of ganglions provides another option of anesthesia with painless experiences, and no pain rebound after surgery. Patients were less anxious about WALANT than GA. Excision can be performed without diathermy usage with similar visualization of the stalk.
TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.
METHODS: We did an individual patient data meta-analysis, in which we searched PubMed and Web of Science for studies published from database inception until April 30, 2019. Studies reporting original biopsy-controlled data of CAP for non-invasive grading of steatosis were eligible. Probe recommendation was based on automated selection, manual assessment of skin-to-liver-capsule distance, and a body-mass index (BMI) criterion. Receiver operating characteristic methods and mixed models were used to assess diagnostic properties and covariates. Patients with non-alcoholic fatty liver disease (NAFLD) were analysed separately because they are the predominant patient group when using the XL probe. This study is registered with PROSPERO, CRD42018099284.
FINDINGS: 16 studies reported histology-controlled CAP including the XL probe, and individual data from 13 papers and 2346 patients were included. Patients with a mean age of 46·5 years (SD 14·5) were recruited from 20 centres in nine countries. 2283 patients had data for BMI; 673 (29%) were normal weight (BMI <25 kg/m2), 530 (23%) were overweight (BMI ≥25 to <30 kg/m2), and 1080 (47%) were obese (BMI ≥30 kg/m2). 1277 (54%) patients had NAFLD, 474 (20%) had viral hepatitis, 285 (12%) had alcohol-associated liver disease, and 310 (13%) had other liver disease aetiologies. The XL probe was recommended in 1050 patients, 930 (89%) of whom had NAFLD; among the patients with NAFLD, the areas under the curve were 0·819 (95% CI 0·769-0·869) for S0 versus S1 to S3 and 0·754 (0·720-0·787) for S0 to S1 versus S2 to S3. CAP values were independently affected by aetiology, diabetes, BMI, aspartate aminotransferase, and sex. Optimal cutoffs differed substantially across aetiologies. Risk of bias according to QUADAS-2 was low.
INTERPRETATION: CAP cutoffs varied according to cause, and can effectively recognise significant steatosis in patients with viral hepatitis. CAP cannot grade steatosis in patients with NAFLD adequately, but its value in a NAFLD screening setting needs to be studied, ideally with methods beyond the traditional histological reference standard.

METHODS: We conducted a randomized controlled study on patients with closed fracture of the distal end of the radius requiring open reduction and plating from January 2019 till April 2020. We recruited 65 patients (33 patients in the WALANT group and 32 patients in the GA group). Randomization was done via block randomization. Data were collected to evaluate preoperative anxiety using the Amsterdam Preoperative Anxiety and Information Scale (APAIS) score, intraoperative pain score during injection (baseline) (V1), 10 minutes after injection (V2), during incision (V3), during gentle manipulation (V4), during aggressive manipulation (V5) and during first drilling of screw (V6), blood loss, duration of surgery and post-operative pain score. Additionally, intraoperative visual analog scale (VAS) score was obtained in the WALANT group. At three weeks, six weeks, three months and six months after operation, the Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) scores and range of motion (ROM) of the wrists were obtained.
RESULTS: The average age in the WALANT group was 47.19 (range, 36-64) years and GA group was 49.48 (range, 38-60) years. The mean APAIS score obtained was 7.78 (WALANT group) and 7.36 (GA group) with no statistical difference. For intraoperative VAS, only during V4 and V5 were the scores 1/10; otherwise at all other phases, the VAS score was 0. The average time for surgery was statistically longer in the WALANT group (61.22 minutes) compared to the GA group (55.33 minutes) (p = 0.003). There was no statistical difference in mean blood loss in both groups. The average post-operative VAS showed statistical significance only at 1 hour and 12 hours post-operation with no statistical difference at 2 and 24 hours post-operation. There was no difference in the post-operative ROM including wrist flexion, extension, supination and pronation for both groups up to six months' follow-up.
CONCLUSION: There was no statistically significant difference in terms of preoperative anxiety level, intraoperative and post-operative VAS score, amount of blood loss and clinical outcome in both groups for plating of the distal end radius. However, the operating time was slightly longer in the WALANT group. We conclude that distal radius plating under WALANT has similar outcomes to GA. In centres with limited resources, WALANT offers a safe, reliable and cheaper option, reserving GA time for head, abdominal and thoracic surgery.
