Oxygen Therapy to Enhance Wound Healing After Revascularization.

Oxygen is one of the important factors for wound healing and infection control. The revascularization procedure is amended to correct the tissue hypoxia problem by increasing the blood flow to obtain an adequate amount of oxygen. Hypoxic wounds are still the issue in the cases of unsuccessful or incomplete revascularization. The issue needs to be clarified and confirmed by proper methods for management to achieve wound healing and prevent limb loss. Oxygen therapy may benefit in the case of remaining hypoxia or wound infection in postrevascularization.

Comprehensive neurosurgical treatment of right occipital arteriovenous malformation with advanced angiographic techniques.

/Summary. A 39-year-old female with a notable medical history of smoking and a familial predisposition to unruptured aneurysms presented with clinical symptoms of intermittent right-sided headaches, flashes of light, and pulsatile tinnitus in the right ear. Diagnostic evaluations, including advanced angiographic techniques, identified a right occipital arteriovenous malformation (AVM). The angiogram revealed significant venous flow voids, emphasizing the need for a comprehensive treatment approach. The Spetzler-Martin grading system classified the AVM as Grade 2, indicating a moderate risk profile. A strategic decision was made to undergo partial embolization of two primary arterial feeders from the right posterior cerebral artery (PCA). Subsequent post-embolization angiograms confirmed a marked reduction in arteriovenous shunting, validating the efficacy of the intervention. The surgical approach encompassed an occipital craniotomy, meticulous subarachnoid dissection, and intraoperative angiography to ensure complete resection. Post-operative assessments showcased a successful and complete AVM resection. The patient experienced a brief, transient headache post-surgery, which resolved on its own. She was discharged on the third post-operative day and has since reintegrated into her professional life. However, she reported a minor visual field deficit, which, while noticeable, did not impede her daily activities. This case underscores the importance of a holistic, patient-centric approach in managing AVMs [1-3]. It challenges the conventional wisdom from the ARUBA trial, advocating for a more nuanced, individualized treatment paradigm, especially for young patients with low-grade AVMs [4].

Needling Point Location Used in Sham Acupuncture for Chronic Nonspecific Low Back Pain: A Systematic Review and Network Meta-Analysis.

Importance: When sham acupuncture is set as a control in evaluating acupuncture, the sham needling technique is usually different from acupuncture. However, the sham procedure is conducted either at the same points that are used for the acupuncture group or at nonindicated points. Objective: To assess whether the outcome of sham acupuncture varies according to the needling points in sham-controlled trials of acupuncture for chronic nonspecific low back pain (CLBP) as an example. Data sources: Searches of MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and the Allied and Complementary Medicine Database were conducted on February 12, 2023. Study selection: Randomized clinical trials (RCTs) assessing the outcomes of acupuncture in sham acupuncture-controlled or waiting list-controlled trials on CLBP were included. Data extraction and synthesis: Two researchers independently extracted data on study characteristics and outcomes and assessed quality. Sham acupuncture was classified according to whether it was conducted at the same acupuncture points used in the acupuncture group, referred to as sham acupuncture therapy (verum) (SATV) or at different points, referred to as sham acupuncture therapy (sham) (SATS). Clinical similarity, transitivity, and consistency tests were conducted, followed by a random-effects frequentist network meta-analysis (NMA). Main outcomes and measures: The primary outcome was pain, and the secondary outcome was back-specific function. The first assessment after the end of treatment was chosen for analysis. Effect sizes are reported as standardized mean differences (SMD) with 95% CIs. The risk of bias was assessed using the Cochrane risk of bias tool, and the certainty of evidence for findings was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation approach. Results: Ten RCTs involving 4379 participants were included. In comparison with SATS, acupuncture was significantly associated with improvements in both pain (SMD, -0.33; 95% CI, -0.52 to -0.15) and function outcomes (SMD, -0.13; 95% CI, -0.25 to -0.02); however, there were no differences between acupuncture and SATV. In comparison with SATS, SATV was significantly associated with better pain (SMD, -0.45; 95% CI, -0.88 to -0.03) and function outcomes (SMD, -0.30; 95% CI, -0.56 to -0.05). The risk of bias that could affect the interpretation of the results was usually low, and the certainty of evidence was moderate to low. Conclusions and relevance: In this NMA, sham acupuncture needling at the same points as those in acupuncture was not a true placebo control for assessing the efficacy of acupuncture for CLBP and might underestimate the outcome of acupuncture in clinical settings.

[Application status and analysis of Fu's subcutaneous needling in the treatment of peripheral facial paralysis].

This paper summarizes the status of application and research of Fu's subcutaneous needling for peripheral facial paralysis, and the characteristics of different stages of peripheral facial paralysis treated with Fu's subcutaneous needling are analyzed from the aspects of intervention timing, protocol design, needle insertion point, sweeping and reperfusion activity, tube retaining time and acupuncture frequency. It is found that there are no norms and standards in sweeping and reperfusion, tube retention and acupuncture frequency in clinical application，and the exploration of staged treatment is insufficient in the research. In the future, it is necessary to form standardized operation to promote clinical promotion, and improve the research on treatment rules and mechanism according to the characteristics of disease stage.

Effect of Fu's subcutaneous needling for cancer pain management: protocol for a pragmatic randomised controlled trial.

INTRODUCTION: Pain is a common symptom in patients with cancer, and pain management is crucial for these patients. Fu's subcutaneous needling (FSN) is a modern acupuncture therapy based on basic medicine commonly used in patients with pain. However, evidence of its effectiveness in treating cancer pain has not been systematically proven. Therefore, this pragmatic randomised controlled trial aims to evaluate the effectiveness and safety of FSN for cancer pain management. METHODS AND ANALYSIS: Overall, 120 eligible patients will be recruited and randomly assigned into two groups using block randomisation. Both groups will be administered analgesic drugs according to the National Comprehensive Cancer Network guidelines. The treatment group will receive FSN therapy one time a day for 6 days. Additionally, we will assess analgesic consumption as the primary outcome and the Numerical Rating Scale, outbreak pain, symptom assessment and adverse events as secondary outcomes to evaluate the effect and safety of FSN in treating cancer pain. The incidence of adverse events will be monitored to assess the safety of FSN. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Ethics Committee of the First Affiliated Hospital of Guangzhou University of Chinese Medicine (approval No: K(2021)096). The results will be published in a peer-reviewed journal, and trial participants will be informed via email and/or phone calls. TRIAL REGISTRATION NUMBER: ChiCTR2200056348.

The USMLE® STEP 1 Pass or Fail Era of the Vascular Surgery Residency Application Process: Implications for Structural Bias and Recommendations.

United States Medical Licensing Examination® (USMLE®) STEP 1 score reporting has been changed to a binary pass/fail format since January 26, 2022. The motives behind this change were (1) the questionable validity of using USMLE STEP 1 as a screening tool during the candidate selection process and (2) the negative impact of using standardized examination scores as an initial gatekeeping threshold for the underrepresented in medicine (URiM) candidates applying to graduate medical education programs, given their generally lower mean standardized exams scores compared to non-URiM students. The USMLE administrators justified this change as a tactic to enhance the overall educational experience for all students and to increase the representation of URiM groups. Moreover, they advised the program directors (PDs) to give more attention to other important qualities and components such as the applicant's personality traits, leadership roles and other extracurricular accomplishments, as part of a holistic evaluation strategy. At this early stage, it is unclear how this change will impact Vascular Surgery Integrated residency (VSIR) programs. Several questions are outstanding, most importantly, how VSIR PDs will evaluate applicants absent the variable which heretofore was the primary screening tool. Our previously published survey showed that VSIR PDs will move their attention to other measures such as USMLE STEP 2 Clinical Knowledge (CK) and letters of recommendation during the VSIR selection process. Furthermore, more emphasis on subjective measures such as the applicant's medical school rank and extracurricular student activities is expected. Given the expected higher weight of USMLE STEP 2CK in the selection process than ever, many anticipate that medical students will dedicate more of their limited time to its preparation at the expense of both clinical and nonclinical activities. Potentially leaving less time to explore specialty pathways and to determine whether Vascular Surgeons  is the appropriate career for them. The critical juncture in the VSIR candidate evaluation paradigm presents an opportunity to thoughtfully transform the process via current (Standardized Letter of Recommendation, USMLE STEP 2CK, and clinical research) and future (Emotional Intelligence, Structure Interview and Personality Assessment) measures which constitute a framework to follow in the USMLE STEP 1 pass/fail era.

[Professor ZHANG Wei-hua's clinical experience in chronic somatic pain treated with zhidong needling techniques].

The paper summarizes professor ZHANG Wei-hua's clinical experience for the treatment of chronic somatic pain with zhidong needling techniques. In terms of the characteristics of chronic somatic pain, professor ZHANG has integrated zhidong needling with acupuncture kinetic therapy. The satisfactory therapeutic effects are obtained by selecting the painful points and regions as the treatment sites and the specific techniques of zhidong needling depending on the size of affected area, the depth of illness, the size and shape of the cord-like muscle, etc. Five techniques of zhidong needling are used accordingly with twirling, pulling, lifting and thrusting, surrounding needling methods involved, as well as with the manipulation speed, direction and frequency considered.

Treatment of postsurgical trigeminal neuralgia with Fu's subcutaneous needling therapy resulted in prompt complete relief: Two case reports.

RATIONALE: Trigeminal neuralgia is a recurrent unilateral transient electroshock-like pain. Fu's subcutaneous needling (FSN), used to treat the musculoskeletal problems, has not been reported in this field. PATIENT CONCERNS: The pain extent of case 1 had no reduction after the previous microvascular decompression, the pain of case 2 relapsed 4 years after the microvascular decompression. DIAGNOSES: Postsurgical trigeminal neuralgia. INTERVENTIONS: FSN therapy was applied on the muscles around the neck and face area, which the myofascial trigger points were palpated in these muscles. The FSN needle was inserted into the subcutaneous layer and the needle tip was pointed toward the myofascial trigger point. OUTCOMES: The following outcome measurements were observed before and after treatment, including numerical rating scale, Barrow Neurology Institute Pain Scale scores, Constant Face Pain Questionnaire scores, Brief Pain Inventory-Facial scores, Patient Global Impression of Change scores, and medication dosage. The follow-up surveys were made after 2 and 4 months respectively. The pain of Case 1 was significantly reduced after 7 times FSN treatments and the pain of Case 2 was even disappeared after 6 times FSN treatments. LESSONS: This case report suggested that FSN can relieve postsurgical trigeminal neuralgia safely and effectively. Clinical randomized controlled studies are needed to be further conducted.

[Empirical analysis on lumbar disc herniation treated with "sinew-bone three needling technique" of Chinese medicine].

The paper presents professor WU Han-qing's experience in treatment of lumbar disc herniation (LDH) with "sinew-bone three needling technique" of Chinese medicine. Based on the theory of meridian sinew, the points are located by "three-pass method" in terms of the distribution of meridian sinew and syndrome/pattern differentiation. The cord-like muscles and adhesion are relieved by relaxing technique to work directly on the affected sites and alleviate the local compression to the nerve root. The needle technique is operated flexibly according to the affected regions involved, due to which, the needling sensation is increased while the safety ensured. As a result, the meridian qi is enhanced, the mind and qi circulation is regulated; and the clinical effect is improved.

A randomized clinical trial of isolated ambulatory phlebectomy versus saphenous thermal ablation with concomitant phlebectomy (SAPTAP Trial).

BACKGROUND: Current treatment of patients with saphenous trunk and tributary incompetence consists of truncal ablation with concomitant, delayed or no treatment of the tributary. However, reflux of the saphenous trunk may be reversible after treatment of the incompetent tributary. The aim of this study was to determine whether single ambulatory phlebectomy with or without delayed endovenous truncal ablation (SAP) is non-inferior to thermal endovenous ablation with concomitant phlebectomy (TAP), and whether SAP is a cost-effective alternative to TAP. METHODS: A multicentre, non-inferiority RCT was conducted in patients with an incompetent great saphenous vein or anterior accessory saphenous vein with one or more incompetent tributaries. Participants were randomized to receive SAP or TAP. After 9 months, additional truncal treatment was considered for SAP patients with remaining symptoms. The primary outcome was VEnous INsufficiency Epidemiological and Economic Study Quality of Life/Symptoms (VEINES-QOL/Sym score) after 12 months. Secondary outcomes were, among others, cost-effectiveness, perceived improvement of symptoms, and anatomical success. RESULTS: Some 464 patients received the allocated treatment (SAP 227, TAP 237). VEINES-QOL scores were 52.7 (95 per cent c.i. 51.9 to 53.9) for SAP and 53.8 (53.3 to 55.1) for TAP; VEINES-Sym scores were 53.5 (52.6 to 54.4) and 54.2 (54.0 to 55.6) respectively. Fifty-eight patients (25.6 per cent) in the SAP group received additional truncal ablation. Treatment with SAP was less costly than treatment with TAP. CONCLUSION: One year after treatment, participants who underwent SAP had non-inferior health-related quality of life compared with those who had TAP. Treatment with SAP was a cost-effective alternative to TAP at 12 months. REGISTRATION NUMBER: NTR 4821 (www.trialregister.nl).

Vascular surgery integrated resident selection criteria in the pass or fail era.

OBJECTIVES: Vascular surgery integrated residency (VSIR) programs are highly competitive; however, criteria for resident selection remain opaque and non-standardized. The already unclear selection criteria will be further impacted by the impending transition of the United States Medical Licensing Examination (USMLE) Step 1 from numeric scores to a binary pass/fail outcome. The purpose of this study was to investigate the historical and anticipated selection criteria of VSIR applicants. METHODS: This was a cross-sectional, nationwide, 59-item survey that was sent to all VSIR program directors (PDs). Data was analyzed using the Fisher exact test if categorical and the Mann-Whitney U test and the Kruskal-Wallis test if ordinal. RESULTS: Forty of 69 PDs (58%) responded to the survey. University-based programs constituted 85% of responders. Most VSIR PDs (65%) reported reviewing between 101 to 150 applications for 1 to 2 positions annually. Forty-two percent of the responding PDs reported sole responsibility for inviting applicants to interview, whereas 50% had a team of faculty responsible for reviewing applications. On a five-point Likert scale, letters of recommendation (LOR) from vascular surgeons or colleagues (a person the PD knows) were the most important objective criteria. Work within a team structure was rated highest among subjective criteria. The majority of respondents (72%) currently use the Step 1 score as a primary method to screen applicants. Regional differences in use of Step 1 score as a primary screening method were: Midwest (100%), Northeast (76%), South (43%), and West (40%) (P = .01). PDs responded that that they will use USMLE Step 2 score (42%) and LOR (10%) to replace USMLE Step 1 score. The current top ranked selection criteria are letters from a vascular surgeon, USMLE Step 1 score and overall LOR. The proposed top ranked selection criteria after transition of USMLE Step 1 to pass/fail include LOR overall followed by Step 2 score. CONCLUSIONS: This is the first study to evaluate the selection criteria used by PDs for VSIR. The landscape of VSIR selection criteria is shifting and increasing transparency is essential to applicants' understanding of the selection process. The transition of USMLE Step 1 to a pass/fail report will shift the attention to Step 2 scores and elevate the importance of other relatively more subjective criteria. Defining VSIR program selection criteria is an important first step toward establishing holistic review processes that are transparent and equitable.

Effect of moxibustion on meridian in a warm needling model: A protocol for a prospective observational study.

BACKGROUND: Warm needling is a type of traditional Chinese medicine (TCM), which uses burned moxa to generate warmth and exerts a therapeutic effect on human skin. Additionally, based on TCM theory, warm needling could improve deficiency-cold syndrome. Research has found that warm needling has analgesic effects as well as effects on the immune system, endocrine system, nervous system, and lower urinary tract symptoms. However, the mechanism of warm needling on the meridians is not fully understood. In modern studies, the electric characteristics of the meridians have been discovered and the combination of semiconductor and TCM theory could explain the meridian phenomena through physics. However, there is no known research exploring the relationship between thermal effect and electric property on the meridians. METHODS: A total of 30 healthy participants older than 20 years of age will be recruited for this study. The participants would first be administered acupuncture, following which the electric characteristics will be measured using the semiconductor analyzer Agilent B1500A/Agilent 4156C. The visual analog score (VAS) will also be rated. Thereafter, a burned moxa will be added to the acupuncture needles as a method for warm needling. The electric characteristics and VAS will be measured again. We will use the paired t-test and repeated measure two-way ANOVA to compare the electric characteristics and VAS before and after warm needling in each participant. OBJECTIVES: This protocol aims to explore the thermal effect on the electric characteristics of meridians in a warm needling model and provide a scientific explanation of TCM through the aspect of physics.

[Professor LIN Guo-hua's experience in the clinical application of "Dayingxiang"].

The paper introduces professor LIN Guo-hua's experience in treatment with acupuncture-moxibustion at "Dayingxiang". Based on the application of Neiyingxiang (internal LI 20), professor LIN defines the entire nasal cavity and its adjacent nasopharynx as "Dayingxiang", of which, "Neiyingxiang" and "Biyandian" (nasopharynx point) are commonly stimulated with acupuncture-moxibustion. "Dayingxiang" may regulate lung qi and promote the circulation of the marrow sea in treatment of the disorders of lung system and the marrow. Fire needling with twirling or burning-scallion technique is predominated in manipulation. "Neiyingxiang" is stimulated for the shallow-located disorders, while, "Biyandian" is for the deep-located ones. These two points are optioned alternatively or in combination to enhance the therapeutic effect.

[Innovation, development and application of contemporary fire needling].

Physicians in the past dynasties have improved the theory of fire needling from the aspects of fire needling instruments, clinical efficacy, application scope, operation, precautions, etc., which promoted the clinical application of fire needling. Modern fire needling breaks through the traditional clinical taboos such as heat syndrome, face, forbidden acupoints, and no needle retention. By using modern fire needling with various types, characteristics and functions, multiple needles and multiple methods are used to treat various diseases, which can further exert the therapeutic effect of fire needling and promote the popularization and application of fire needle therapy.
