Randomized Controlled Trial
Therapeutic options for acne scars include subcision and suction with microdermabrasion, but these treatment modalities have not been studied in conjunction. To compare effectiveness of subcision alone versus subcision with suction for the treatment of facial acne scars. Randomized, split-faced, evaluator-blinded control trial. Participants underwent one subcision treatment on both sides of the face followed by 10 sessions of suction to one side. Photographs at baseline, 1-month, and 4-months were assessed. Primary outcome measures were the validated Acne Scar Severity Scale (ASSS) (0 = no acne scarring, 4 = severe), Acne Scar Improvement Grading Scale (ASIGS) (-100 to 100%), and modified Quantitative Global Scarring Grades (QGSG) (point-based questionnaire instrument), as well as subject preference. Twenty-eight treatment areas and 154 treatments were analyzed. Dermatologist raters found no differences between subcision alone and subcision-suction at 1-month or 4-months. Mean subject-assessed percent improvement for subcision-suction was higher than that for subcision alone at 1-month (37% versus 24%, p = 0.04) but not at 4-months (p = 0.37). Subjects preferred combination therapy to monotherapy at 1-month (50% vs. 21%) and 4-months (43% vs. 21%). While blinded raters did not detect significant differences, subjects perceived combination treatment as working more quickly than monotherapy, and preferred combination treatment at all time points.Clinical trial registration NCT01696513 on Clinicaltrials.gov.

BACKGROUND
The umbilicus detachment and reinsertion in umbilical float mini-abdominoplasty results in its lower position with or without shape distortion. This event creates a stigmatizing look, elongating the upper abdomen and creating variable grades of infra umbilical/pubis bulging. This lack of proportion causes an unpleasant, artificial look, and is very difficult to fix. The study aimed to describe a sequence of abdominoplasty and combined upper abdomen horizontal muscle plications to correct umbilicus malposition after a mini-abdominoplasty.
METHODS
Over a period of 24 months, 12 patients underwent a liposuction (suction-assisted liposuction) and abdominoplasty with horizontal supraumbilical muscle plication. All patients underwent objective measurements before and after the procedure, using digital image measurements by Mirror Image software, version 6.0 (Fairfield, N.J.). The follow-up evaluation was performed 12 months postoperatively. Statistical analysis was performed using IBM SPSS Statistics V26.
RESULTS
Over 24 months, 12 patients (100%), who underwent abdominoplasty combined with horizontal plication in the upper abdominal wall, have shown adequate umbilicus elevation (2.98 ± 0.242 cm; 95% confidence level), restoring the abdominal muscle wall proportion at 12 months follow-up. One patient (8%) had a seroma, and one (8%) had a small muscular hernia (1.5 cm) in the lower abdomen.
CONCLUSIONS
The combination of abdominoplasty and upper horizontal muscle plication can fix the malpositioned umbilicus, restoring the aesthetic and anatomic proportions in those patients who underwent an umbilical float mini-abdominoplasty.

Suction grippers offer a distinct advantage in their ability to handle a wide range of items. However, attaching these grippers to irregular and rough surfaces presents an ongoing challenge. To address this obstacle, this study explores the integration of magnetic intelligence into a soft suction gripper design, enabling fast external magnetic actuation of the attachment process. Additionally, miniaturization options are enhanced by implementing a compliant deploying mechanism. The resulting design is the first-of-its-kind magnetically-actuated deployable suction gripper featuring a thin magnetic membrane (Ø 50 mm) composed of carbonyl iron particles embedded in a silicone matrix. This membrane is supported by a frame made of superelastic nitinol wires that facilitate deployment. During experiments, the proof-of-principle prototype demonstrates successful attachment on a diverse range of curved surfaces in both dry and wet environments. The gripper achieves attachment on curved surfaces with radii of 50-75 mm, exerting a maximum attachment force of 2.89 ± 0.54 N. The current gripper design achieves a folding percentage of 75%, enabling it to fit into a Ø 12.5 mm tube and access hard-to-reach areas while maintaining sufficient surface area for attachment forces. The proposed prototype serves as a foundational steppingstone for further research in the development of reliable and effective magnetically-actuated suction grippers across various configurations. By addressing the limitations of attachment to irregular surfaces and exploring possibilities for miniaturization and precise control, this study opens new avenues for the practical application of suction grippers in diverse industries and scenarios.

OBJECTIVE
To analyze the potential factors influencing the diagnostic capability of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and provide medication treatment recommendations for patients with pancreatic solid mass lesions.
METHODS
A retrospective analysis was conducted on clinical data of 92 patients with pancreatic solid mass lesions who underwent EUS-FNA examination after detection by imaging studies. The diagnostic effectiveness of EUS-FNA was evaluated based on cytological or histological examination results. Logistic regression analysis was subsequently performed to analyze the potential factors influencing the diagnostic capability of EUS-FNA in patients with pancreatic solid mass lesions.
RESULTS
EUS-FNA was successfully performed in all 92 patients, with a puncture success rate of 100.00%. Only one patient experienced transient hyperamylasemia, which resolved with conservative treatment. No other serious complications were observed. Among the 92 patients, 70 patients obtained a definite diagnosis after EUS-FNA (Group A), while 22 patients did not achieve a definite diagnosis (Group B) after the procedure. Univariate analysis showed that lesion size, dilation of the pancreatic duct or bile duct, negative pressure, and suction method were significantly different between Group A and Group B (P < .05). Multivariate logistic regression analysis revealed that lesion size, dilation of the pancreatic duct or bile duct, negative pressure, and suction method were potential factors influencing the diagnostic ability of EUS-FNA in patients with solid pancreatic lesions (P < .05).
CONCLUSION
EUS-FNA has a high diagnostic value in the evaluation of solid pancreatic lesions. Lesion size, dilation of the pancreatic duct or bile duct, negative pressure, and suction method are potential factors influencing the diagnostic ability of EUS-FNA in patients with solid pancreatic lesions. In terms of medical treatment, specific treatment methods and drug choices should be based on a comprehensive evaluation of the nature of the patient's lesions and the severity of the condition.

The acetabular labrum plays a key role in proper biomechanical hip function through creation or maintenance of a suction seal between the femoral head and acetabulum. The suction seal effect has been shown to provide stability within the hip, improve biomechanics, and decrease the chance for long-term development of osteoarthritis by optimizing function and force distribution within the hip. Femoral acetabular impingement syndrome damages the labrum and chondrolabral junction, thus negatively impacting the ability of the labrum to maintain native suction seal. Our technique describes the use of a postless hip arthroscopy table and the on-off traction technique throughout the labral repair, ensuring precise reduction of the labrum and restoration of the suction seal sequentially as anchors are placed.

Observational Study
AIMS
Debulking of infective mass to reduce the burden if infective material is a fundamental principle in the surgical management of infection. The aim of this study was to investigate the validity of this principle in patients undergoing transvenous lead extraction in the context of bloodstream infection (BSI).
METHODS AND RESULTS
We performed an observational single-centre study on patients that underwent transvenous lead extraction due to a BSI, with or without lead-associated vegetations, in combination with a percutaneous aspiration system during the study period 2015-22. One hundred thirty-seven patients were included in the final analysis. In patients with an active BSI at the time of intervention, the use of a percutaneous aspiration system had a significant impact on survival (log-rank: P = 0.0082), while for patients with a suppressed BSI at the time of intervention, the use of a percutaneous aspiration system had no significant impact on survival (log-rank: P = 0.25).
CONCLUSION
A reduction of the infective burden by percutaneous debulking of lead vegetations might improve survival in patients with an active BSI.

We present a case of an adolescent patient with a penetrating gunshot wound to the mouth requiring endotracheal intubation via rapid sequence intubation in the prehospital setting. The team used video laryngoscopy (VL) to secure the airway; however, continuous bloody secretions increased the complexity of the procedure and required the application of the Suction-Assisted Laryngoscopy and Airway Decontamination (SALAD) method to facilitate intubation. By utilizing the SALAD procedure, the field of view on the VL camera remained unobscured, and the patient's airway remained clear, allowing for an uneventful intubation procedure. No episodes of hypoxia, hypotension, bradycardia, or obvious clinical signs of pulmonary aspiration occurred during the procedure. The patient was transported to a local Pediatric Level I trauma center, where he underwent emergent surgery to repair an esophageal laceration and was discharged to home 40 days later. This case highlights the importance of deliberate and proactive management of the contaminated airway in the prehospital setting. The SALAD technique replaces the Yankauer suction catheter with a larger bore suction catheter in conjunction with VL to perform gross decontamination of the mouth and airway before attempting intubation. This is followed by permanently placing the large bore suction catheter under constant suction in the posterior pharynx or esophagus to keep the VL camera unobscured by vomit or blood to facilitate intubation. After the intubation, the suction catheter may be removed unless ongoing suction is required. Keeping the VL camera unobscured during the procedure may improve first-pass intubation success rate.

INTRODUCTION
Biofilm contributes significantly to bacterial persistence in endoscope channels. Enhanced cleaning methods capable of removing biofilm from all endoscope channels are required to decrease infection risk to patients. This head-to-head study compared cyclic build-up biofilm removal of an automated endoscope channel cleaner (AECC) with standard manual cleaning according to instructions for use (IFU) in polytetrafluorethylene channels.
METHODS
Cyclic build-up biofilm was grown in 1.4-mm (representing air/water and auxiliary channels) and 3.7-mm (representing suction/ biopsy channels) inner diameter polytetrafluorethylene channels. All channels were tested for residual total organic carbon, protein, and viable bacteria. Internationally recognized ISO 15883-5:2021 alert levels were used as cleaning benchmarks for protein (3 μg/cm) and total organic carbon (6 μg/cm).
RESULTS
The automated cleaner significantly outperformed manual cleaning for all markers assessed (protein, total organic carbon, viable bacteria) in 1.4-mm and 3.7-mm channels representing air/water/auxiliary and suction/biopsy channels, respectively. Manual cleaning failed to remove biofilm from the air/water and auxiliary channels. According to the IFU, these channels are not brushed, suggesting a potential root cause for a portion of the numerous endoscopy-associated infections reported in the literature.
CONCLUSION
AECC shows potential to deliver enhanced cleaning over current practice to all endoscope channels and may thereby address infection risk.

Dredged sediment poses significant challenges for transportation and subsequent treatment due to its high water content and large volume. Coagulation, a common method of dewatering, can significantly enhance the dewatering performance of dredged sediment. This study synthesized a cationic starch-based flocculant [starch-3-chloro-2-hydroxypropyl trimethylammonium chloride (St-CTA)] through etherification for the flocculation dewatering of dredged sediment. The effectiveness and mechanism of St-CTA as a dewatering flocculant for dredged sediment were investigated. The results demonstrated that when the dosage of St-CTA was 12 mg g TSS (total suspended solids), the dehydration property of dredged sediment substantially improved, with the specific resistance to filtration (SRF) decreasing by 93.3%, the capillary suction time (CST) by 93.5%, and the water content of the filter cake (WC) by 9.7%. The removal rate of turbidity of the supernatant from the conditioned dredged sediment reached 99.6%, accelerating the settling speed and effectively capturing and separating fine particles from the sediment. St-CTA significantly increased the median particle size (D50), altered the microstructure and extracellular polymeric substances (EPS) of the flocs, and increased the fractal dimension of the flocs, making them more compact and conducive to the formation of drainage channels. These findings confirm the feasibility of using potentially environmentally friendly St-CTA as a rapid dewatering conditioning agent for sediment.
