BACKGROUND: Minimally invasive bleb surgery using the XEN-45 gel stent has not been established for the treatment of normal-tension glaucoma (NTG). The main objective of this study was to evaluate the long-term treatment efficacy and safety of XEN-45 in eyes with uncontrolled NTG.
METHODS: A retrospective analysis of patients with NTG who underwent XEN-45 gel stent implantation at university hospital Tuebingen between 2016 and 2021. The primary outcome measure was surgical success after three years defined as lowering of intraocular pressure (IOP) of ≥ 20%, with target IOP between 6 and 15 mmHg. Success was complete without and qualified irrespective of topical antiglaucoma medication use. The need for further glaucoma surgery, except for needling, was regarded as a failure. The secondary outcome measures included changes in mean IOP, number of antiglaucoma medications, and needling and complication rates.
RESULTS: Twenty-eight eyes from 23 patients were included in the final analysis. Complete and qualified success rates were 56.5% and 75% after three years, respectively. Mean postoperative IOP ± standard deviation decreased significantly after three years from 19.3 ± 2.0 mmHg at baseline to 13.7 ± 4.2 mmHg (n = 22; p < 0.0001). The median number of antiglaucoma medications decreased from 2 (range 0-4) to 0 after three years (range 0-3; p < 0.0001). Sixteen eyes (57%) required a median of 1 (range 1-3) needling procedures. One eye required further glaucoma surgery. No sight-threatening complications were observed.
CONCLUSIONS: The XEN-45 stent is effective and safe for the long-term treatment of NTG. However, needling was frequently required to improve outcomes.

BACKGROUND: The success of haemodialysis (HD) critically depends on the effective use of arteriovenous fistulas (AVFs). The precise needling technique is vital to minimise complications and ensure functional vascular access.
OBJECTIVE: This study assesses the effectiveness of a nursing consultation protocol, which integrates physical examination (PE) with Doppler Ultrasound (DUS), in preparing patients for the first AVF needling.
METHODS: A cross-sectional analysis at a Portuguese National Health Service Hospital engaged thirty new HD patients, four HD needling experienced nurses and one HD vascular access nurse. This study examines the accuracy of PE in assessing the matured AVF by the four nurses compared to a trained vascular access nurse encompassing systematic PE and DUS.
METHODS: The primary data incorporated AVF characteristics derived from PE (inspection, palpation, and auscultation) and DUS findings (vein depth, diameter, and blood flow). A secondary focus was evaluating the change in nurses\' perceived needling complexity following the nursing consultation.
RESULTS: The nursing consultation significantly enhanced the identification of crucial AVF features, such as accessory veins (p = 0.002), and improved the accuracy of AVF morphology assessments. This led to identifying longer needling tracks (p = 0.031) and a higher number of safe needling points (p = 0.016). Nurses reported a notable reduction in perceived complexity and potential adverse events following this method (p = 0.027).
CONCLUSIONS: Integrating structured PE with DUS in a nursing consultation framework significantly improves the preparation for AVF needling. This approach enhances the efficiency and safety of AVF needling and boosts nurse confidence and patient care in HD settings.

BACKGROUND: Evidence suggests the plantar fascia and its interphase with the flexor digitorum brevis muscle can play a relevant role in plantar heel pain. Needling interventions could offer an appropriate treatment strategy to addressing this interface.
OBJECTIVE: We compared the accuracy and safety of ultrasound-guided versus palpation-guided procedures for the proper targeting of the interface between the plantar fascia and the flexor digitorum brevis with a solid needle.
METHODS: A crossover cadaveric study was conducted. Five experienced therapists performed a series of 20 needle insertions each (n = 100 in total, 10 landmark-guided and 10 ultrasound-guided) on 10 anatomical samples. The therapists were instructed to accurately place the needle on the interface between the plantar fascia and the flexor digitorum brevis muscle. The distance of the tip of the needle to the identified target (accuracy), the surrounding sensitive structures targeted (safety), the time needed for the procedure, the number of needle passes, and the needle length outside the skin were assessed.
RESULTS: The ultrasound-guided technique was associated with a significantly higher accuracy (p < 0.001) but without differences in safety (p = 0.249) as compared to the palpation-guided procedure.
CONCLUSIONS: Our results suggest that ultrasound-guided insertion exhibits greater accuracy but not greater safety than palpation-guided insertion when targeting the interface between the plantar fascia and the flexor digitorum brevis.

BACKGROUND: Hypertrophic bleb is a rare complication of glaucoma filtration surgery characterized by an elevated bleb extended through the nasal 180 degrees of the eye and usually with a normal IOP. Currently, there is little experience and no existing standardized treatment. We describe a new method called modified superior bleb needling and evaluate the clinical outcomes in affected eyes.
METHODS: In this retrospective, consecutive interventional case series, patients who developed hypertrophic blebs after trabeculectomy from November 2015 to August 2020 at West China Hospital were enrolled. We innovatively adopted a modified superior bleb needling to allow aqueous humor to outflow into the superior subconjunctival space. Repeat needlings were performed if necessary. The technical and clinical success rate and complications were reported.
RESULTS: At the time of the last follow-up, complete success was achieved in 8/10 patients, qualified success was achieved in 9/10 patients, and failure was achieved in 1/10 patients. Eight patients had a low filtering bleb and IOP ≤21 mmHg. There was no statistically significant difference between the preneedling and postneedling IOP (p > 0.05).
CONCLUSIONS: Modified superior bleb needling is effective for hypertrophic blebs after trabeculectomy, and there was no significant impact on anterior chamber depth or IOP, making it a viable or preferred alternative option. It is worthy of further study and wider usage.

The XEN45 is a minimally invasive glaucoma surgery device commonly used in clinical practice. This retrospective study included consecutive patients with open-angle glaucoma who underwent a XEN45 implant with mitomycin C, either alone or in combination with phacoemulsification, between June 2015 and March 2021. The primary end point was the mean change in intraocular pressure (IOP) from the baseline to month 6. A total of 677 eyes, 395 (58.3%) in the XEN alone group and 282 (41.7%) in the XEN+Phaco group, were included in this study. The preoperative IOP was significantly lowered from 28.7 ± 8.6 mmHg and 25.4 ± 6.9 mmHg to 13.5 ± 5.0 mmHg and 13.5 ± 4.1 mmHg at month 6 in the XEN solo and XEN+Phaco groups, respectively, with p < 0.0001 each. The mean (95% confidence interval) number of ocular hypotensive medications was significantly reduced from 3.3 (3.2-3.4) to 0.2 (0.1-0.2) and from 3.1 (2.9-3.2) to 0.2 (0.1-0.2) in the XEN solo and XEN+Phaco groups, respectively, with p < 0.0001 each. Needling was performed in 228 (33.7%) eyes. Conclusions: the XEN implant significantly reduces both IOP and the number of ocular hypotensive medications. IOP lowering was higher in the XEN solo group than in the XEN+Phaco one, although such a difference was only evident during the first month after surgery.

Ripasudil, a rho-associated protein kinase inhibitor ophthalmic solution, shows a protective effect in preventing excessive scarring in vitro. This study aims to evaluate the safety and efficacy of ripasudil for glaucoma patients submitted to the needling procedure. In this prospective, multicenter, single-arm study, we included 20 eyes of 20 patients with glaucoma who underwent the needling procedure without antimetabolites. All patients administered ripasudil after needling for three months. The primary endpoint of this study was the safety of ripasudil in patients, and the secondary endpoint was the change in IOP at 12 weeks after the needling procedure. No serious complications were found in the patients. One eye experienced pruritus and conjunctival follicle, while another eye had conjunctival follicle. These complications were transient and resolved quickly after discontinuation of ripasudil. The mean preoperative IOP was 14.6 ± 4.6 mmHg, which decreased to 11.0 ± 4.7 mmHg (p = 0.0062) at 1 week postoperatively. The IOP reduction effect continued to 12 weeks (11.8 ± 3.1 mmHg; p = 0.0448). The administration of the ROCK inhibitor, ripasudil, after the needling procedure is safe and effective in maintaining IOP for 12 weeks.

BACKGROUND: Microinvasive glaucoma surgery (MIGS) is a growing trend, and XEN gel implant is one of the most effective types of MIGS. This study aimed to examine factors associated with the surgical success of XEN gel implants.
METHODS: This retrospective cohort study enrolled patients with glaucoma receiving XEN implantation alone or combined with phacoemulsification (PHACOXEN) with a follow-up period of more than 6 months at Hualien Tzu Chi Hospital, Taiwan. If intraocular pressure (IOP) elevated above 20 mmHg during the follow-up, needling or open revision was performed. The primary outcome measures included IOP and the number of glaucoma medications.
RESULTS: Male patients had lower postoperative IOP; male patients and higher preoperative IOP were associated with higher IOP change rates, and older patients had a higher chance of achieving IOP < 18 mmHg and being medication-free at months 12, 24, and 36. The Kaplan-Meier curve showed that the probability of free-of-rescue intervention over the follow-up period was not different between the XEN alone and the PHACOXEN group (P = 0.859). Both needling and open revision were effective rescue interventions, but open revision had a higher chance of achieving IOP ≤ 18 mmHg and being medication-free (P = 0.031) and required less medication afterward (P = 0.044). Older age (P = 0.013) and male patients (P = 0.022) had a lower IOP after rescue interventions. Compared with open revision, needling was associated with higher IOP (P = 0.048) and more required medications (P = 0.048).
CONCLUSIONS: XEN alone and PHACOXEN had comparable surgical outcomes, whereas open revision had a better IOP lowering effect than needling as a rescue intervention. Male and older patients had better surgical results in primary XEN implantations and rescue interventions.

Acupuncture is gaining popularity and wider acceptance as a treatment modality within the field of sports medicine. Our objective was to provide a comprehensive review of the existing literature pertaining to acupuncture in sports medicine to shed light on approaches utilized in acupuncture while revealing its personalized nature and its impact on athletes\' preparation, performance, and recovery. We evaluated acupuncture research in the context of medicine and sports-related injury treatment, assessing its impact on athletic performance across demographics of athletes. Athletes participating in most sports have shown positive outcomes from acupuncture interventions. Acupuncture improves peak oxygen levels, maximum heart rate, delayed-onset muscle soreness, pain, swelling, explosive force production, and joint mobility. Furthermore, the efficacy of acupuncture appears to be similar regardless of age and sex. Lastly, the acceptance of acupuncture is influenced by cultural factors, with Western and traditional East Asian cultures exhibiting distinct perspectives on its rationale and mechanisms of action. Traditional East Asian acupuncturists typically employ qi and meridian theories in their acupuncture practices, with the recent incorporation of Western concepts. Acupuncture shows promise as an effective treatment for musculoskeletal pain and neuropathies in athletes across different age groups and for addressing injuries in various sports. Our comprehensive review will enhance our understanding of acupuncture\'s potential as a complementary or distinct therapeutic approach compared to conventional therapies. Additionally, our review explores its specific applications within different sports and delves into the cultural dimensions involved in integrating this practice into modern sports medicine.

We have read the article titled \"Laser Speckle Contrast Imaging Guides Needling Treatment of Vascular Complications from Dermal Fillers\" by Tsai et al. in Aesthetic Plastic Surgery, and we are deeply interested in their research. The study explores the use of laser speckle contrast imaging (LSCI) for evaluating and treating vascular complications in six patients who experienced issues after facial dermal filler injections. The authors found that LSCI accurately and noninvasively identified vascular occlusions in real time, surpassing the accuracy of visual and photographic assessments. This suggests that LSCI can be a valuable tool for clinicians to monitor therapeutic outcomes following interventions for vascular occlusions. While we appreciate the study\'s significance and quality, we have specific concerns regarding the methodologies employed to prevent complications related to hyaluronic acid (HA). Understanding the properties of the active substance is crucial for standardization in medical treatments. A comprehensive understanding of HA\'s essential characteristics is vital to determine if correlations exist between these properties, treatment outcomes, and the risk of complications. Key considerations include rheology, which studies how matter flows and deforms under strain, viscosity, elasticity, cohesiveness, and gel texture. These factors play a vital role in the safety and efficacy of dermal filler treatments.Level of Evidence V This journal requires that authors assign a level of evidence to each article.

BACKGROUND: Although laser Doppler imaging (LDI) accurately delineates a hypoperfused area to help target hyaluronidase treatment, laser speckle contrast imaging (LSCI) is more appropriate for assessing microvascular hemodynamics and has greater reproducibility than LDI. This study investigated the use of LSCI in the evaluation and treatment of six patients who developed vascular complications after facial dermal filler injections.
METHODS: The areas of vascular occlusion were accurately defined in real time by LSCI and were more precise than visual inspections or photographic evidence for guiding needling and hyaluronidase treatment.
RESULTS: All patients had achieved satisfactory outcomes as early as Day 2 of treatment and no procedure-related complications were reported after a median follow-up of 9.5 (7-37) days.
CONCLUSIONS: LSCI accurately and noninvasively delineated vascular occlusions in real time among patients experiencing complications of facial dermal filler injections. Moreover, LSCI was more accurate than visual and photographic evaluations. Clinicians can use LSCI to reliably follow-up therapeutic outcomes after salvage interventions for vascular occlusions.
