ABSTRACT

OBJECTIVE: To compare the efficacy of different acupuncture frequencies in tobacco-dependent patients and explore the impact of nicotine metabolite rate (NMR) on smoking cessation in the intervention with acupuncture.

METHODS: A total of 120 cases of tobacco-dependent patients were randomly divided into a high-frequency group (60 cases, 12 cases dropped off) and a low-frequency group (60 cases, 6 cases dropped off). In the two groups, smoking cessation counseling was provided prior to acupuncture. Acupuncture was applied to Baihui (GV 20), Lieque (LU 7), Zusanli (ST 36), etc. Additionally, electric stimulation was added at Lieque (LU 7) and Zusanli (ST 36), with continuous wave, 15 Hz in frequency. The duration of treatment was 8 weeks in either group. In the high-frequency group, the treatment was given 5 times weekly from week 1 to week 4, and was 3 times weekly from week 5 to week 8. In the low-frequency group, the treatment was given 3 times weekly from week 1 to week 4, and was twice a week from week 5 to week 8. The immediate withdrawal rate, persistent withdrawal rate, the score of Fagerstrőm test for nicotine dependence (FTND) before and after treatment, as well as the score of Minnesota nicotine withdrawal scale (MNWS) in 1 and 8 weeks of treatment were compared among the patients with high and low NMR between the two groups separately. The Logistic regression analysis was used to screen the influencing factors of smoking cessation in the intervention with acupuncture.

RESULTS: After treatment, there was no statistical significance of the differences in the immediate withdrawal rate (35.4% [17/48] vs 29.6% [16/54]) and the persistent withdrawal rate (33.3% [16/48] vs 25.9% [14/54]) between the high-frequency group and the low-frequency group (P>0.05). The difference in withdrawal rate had no statistical significance between high and low NMR patients (P>0.05). FTND scores after treatment were lower than those before treatment (P<0.01) and MNWS scores were lower than those in 1 week of treatment (P<0.01) in the two groups. However, the differences had no statistical significance between the two groups and between the patients with high NMR and low NMR (P>0.05). Age, education level and NMR were the influencing factors of smoking cessation in the intervention with acupuncture (P<0.05).

CONCLUSION: Acupuncture with different frequencies has no obvious impact on the efficacy in tobacco-dependent patients. The lower nicotine metabolite rate in individuals, the better efficacy of acupuncture. The smokers with high nicotine metabolite rate may obtain a better effect of cessation in the high-frequency intervention with acupuncture.

ABSTRACT

BACKGROUND: Initial results after autologous fat transfer for treatment of thumb carpometacarpal joint osteoarthritis have been promising. But long-term results have not yet been available.

METHODS: In a prospective study, 42 patients with thumb carpometacarpal joint osteoarthritis were observed for a mean time of 5 years after autologous fat transfer. Manual liposuction and centrifugation were performed. Pain rating according to numerous analogue pain scale; objective force of pinch grip and fist closure; and Disabilities of the Arm, Shoulder, and Hand questionnaire score (DASH score) before and after treatment were analysed.

RESULTS: The average pain preoperatively was 8.0 ± 1.6 and 4.0 ± 3.0 after 5 years overall. Force and pinch force of the treated hand improved from 71% and 60% preoperative in comparison to the non-treated hand to 100% and 96%, respectively, 5 years after fat transplantation. There were similar improvements for the parameters strength and DASH score. All improvements were statistically significant. No serious adverse events were observed.

CONCLUSIONS: Autologous fat transplantation is a real alternative to trapeziectomy even in the long term in basal joint osteoarthritis of the thumb. The low invasiveness of the procedure and early recovery of patients compared with classical procedures such as trapeziectomy, and the superior long-term results compared with classical injection therapy, make this approach feasible as a first-line therapy in basal joint osteoarthritis of the thumb as it offers stable results and warrants a high patient satisfaction rate.

ABSTRACT

PURPOSE: In addition to direct oncologic therapy, interventional radiology plays an important supportive role in oncologic therapy primarily guided by other disciplines. These supporting measures include diagnostic punctures, drainages, biliary interventions, central venous access including port implantations, osteoplasties, pain therapies etc.). This study investigated the extent to which these radiologically guided supportive measures are available in Germany.

MATERIAL AND METHODS: All interventional procedures documented in the DeGIR-registry (excluding transhepatic portosystemic shunts) of the years 2018 and 2019 were recorded (DeGIR-module C). A breakdown of the documented interventions was performed based on federal states as well as 40 individual regions (administrative districts and former administrative districts).

RESULTS: A total of 136,328 procedures were recorded at 216 centers in DeGIR Module C in 2018 and 2019. On average, 389 cases were documented per hospital in 2018 and 394 cases in 2019; the increase per hospital from 2019 is not statistically significant but is relevant in the aggregate when new participating centers are included, with an overall increase of 10 % (6,554 more cases than the previous year). Normalized to one million inhabitants, an average of 781 procedures took place across Germany in 2018 and 860 in 2019. Districts with no registered procedures are not found for Module C.Indications for Module C interventions were mostly interdisciplinary in 2018 and 2019. In this context, the quality of outcome was very high; for the procedures drain placement, marking and biopsy the technical success was 99 %, while the complication rate was lower than 1 %.

CONCLUSION: The structural analysis of this work concludes that in Germany there is good nationwide availability of radiologically guided supportive measures in oncological therapy. Accordingly, the training situation for prospective interventional radiologists is good, as the distribution to centers with high experience is excellent. In addition, the overall outcome quality of radiology-guided interventions is very high.

KEY POINTS: · In Germany, there is good nationwide coverage of radiologically guided supportive interventions in oncological therapy.. · The training situation for prospective interventional radiologists is good, as the distribution to centers with high experience is excellent.. · The overall outcome quality of radiology-guided interventions is very high..

ABSTRACT

This study aims to analyze the functional outcomes and lateral knee stability of patients who underwent lateral collateral ligament (LCL) and biceps femoris tendon reconstruction with suture anchors after proximal fibula en bloc resection for bone tumors. Patients who underwent proximal fibular en bloc resection between 2007 and 2018 were retrospectively viewed. Patients were invited to visit the clinic, and their functional scores were evaluated using the Musculoskeletal Tumor Society Scoring (MSTS) system. Lateral knee stability was evaluated by varus stress radiographs obtained at 20 degrees of flexion, and the range of motion (ROM) of the bilateral knee was assessed. Side-to-side differences were graded according to the International Knee Documentation Committee (IKDC) criteria and compared between types I and II resections. A total of 17 patients (4 males and 13 females) with a mean age of 31.1 ± 17.1 (range: 13-65) years at the time of surgery were available for radiological and clinical examination at a mean follow-up of 68.6 ± 36.4 (range: 22-124) months after surgery. In terms of ROM measurements, IKDC grades and side-to-side differences in both flexion and extension were not significantly different between the groups. On varus stress radiographs, lateral knee gapping was measured to be 0.93 ± 0.91 mm in type-I resections and 1.83 ± 0.45 mm in type-II resections, and statistically significant differences were detected among the groups (p = 0.039). When the values were graded according to IKDC criteria, none of the knees were classified as abnormal, and no difference was observed between the groups. Mean MSTS score of patients with type-I resections was significantly higher than those of patients with type-II resections (92.7 vs. 84.4%, p = 0.021). In the subscale analysis, a significant difference was observed in the support scores (type I = 94.5%, type II = 70%; p = 0.001). The reattachment of LCL and biceps femoris tendon to the tibial metaphysis with a suture anchor is a simple and effective method to prevent lateral knee instability after proximal fibula resections.

ABSTRACT

PURPOSE: To evaluate cardiac MRI characteristics in patients with suspected hypersensitivity myocarditis following mRNA COVID-19 vaccination.

MATERIALS AND METHODS: Patients clinically suspected of acute myocarditis after COVID-19 vaccination were retrospectively analyzed and compared against a healthy control group. Cardiac MRI protocol included parameters such as T1 and T2 relaxation times, extracellular volume (ECV), T2 signal intensity ratio, and late gadolinium enhancement (LGE). Lymph node size was assessed in the patient group on the injection side. Student t-test, analyses of variance (ANOVA) with Tukey post-hoc test, and χ² test were used for statistical analysis.

RESULTS: 20 patients with clinically suspected post-vaccine myocarditis (28 ± 12 years; 12 men) and 40 controls (31 ± 11 years; 25 men) were evaluated. According to the 2018 Lake Louise criteria (LLC), patients with clinically suspected myocarditis were further subdivided into an LLC-positive group (n = 9) and an LLC-negative group (n = 11). The mean time of symptom onset after vaccination was 1.1 ± 1.2 days (LLC-positive) and 6.5 ± 9.2 days (LLC-negative). Group differences in inflammatory variables between myocarditis patients and control subjects were more pronounced in the LLC-positive group (e. g., T1 relaxation time: 1041 ± 61 ms [LLC positive] vs. 1008 ± 79 ms [LLC-negative] vs. 970 ± 25 ms [control]; p <.001; or T2 signal intensity ratio 2.0 ± 0.3 vs. 1.6 ± 0.3 [LLC-negative] and vs. 1.6 ± 0.3 [control], p = .012). LLC-positive patients were significantly faster in receiving an MRI after initial symptom onset (8.8 ± 6.1 days vs. 52.7 ± 33.4 days; p = .001) and had higher troponin T levels (3938 ± 5850 ng/l vs. 9 ± 11 ng/l; p <.001). LGE lesions were predominantly located at the subepicardium of the lateral wall. Axillary lymphadenopathy was more frequent in the LLC-positive group compared to the LLC-negative group (8/9 [89 %] vs. 0/11 [0 %], p < 0.001).

CONCLUSION: Vaccine-induced myocarditis should be considered in patients with acute symptom onset after mRNA vaccination, especially if elevated serum troponin T is observed. Imaging findings of vaccine-induced myocarditis are similar to virus-induced myocarditis, allowing for the use of the Lake Louise Criteria for diagnostic purposes.

KEY POINTS: · Vaccine-induced hypersensitivity myocarditis can be confirmed with cardiac MRI. · Especially patients with sudden onset of symptoms and elevated serum troponin T had positive cardiac MRI findings. · Cardiac MRI characteristics of vaccine-induced myocarditis are similar to those in virus-induced myocarditis.

ABSTRACT

IMPORTANCE: A better understanding of the effect of elective cesarean delivery (CD) on the development of pelvic floor disorders can help obstetricians counsel pregnant women.

OBJECTIVE: This study aimed to perform a systematic review and meta-analysis evaluating whether primary elective CD is protective against pelvic floor disorders.

STUDY DESIGN: Using the MOOSE criteria, electronic databases were searched for studies that compared the prevalence of pelvic floor disorders among primiparous women. Outcomes of interest were urinary incontinence (UI), fecal incontinence (FI), anal incontinence (AI), and pelvic organ prolapse (POP). Comparisons were made between CD before the onset of labor (“Elective CD”), CD after trial of labor (“Labor CD”), and vaginal delivery (VD). Risk ratios (RRs) were computed using STATA. Between-study heterogeneity was assessed via Cochrane’s homogeneity test and review of the I2 statistic.

RESULTS: Nineteen studies were included. The overall prevalence of UI for Elective CD was estimated at 7% (95% confidence interval [CI], 3%-13%), Labor CD at 14% (95% CI, 8%-21%), and VD at 26% (95% CI, 20%-32%). Meta-analysis demonstrated a decreased risk of UI after Elective CD compared with Labor CD (RR, 0.75; P = 0.011) or VD (RR, 0.43; P < 0.001). There was a decreased risk of FI or AI after Elective CD compared with VD, but not when compared with Labor CD. Only 2 studies examined POP, precluding meta-analysis.

CONCLUSIONS: Among primiparous women, Elective CD may be protective against UI when compared with Labor CD. There was not a protective effect of Elective CD against FI and AI when compared with Labor CD. More data on the effect of elective CD on POP are needed.

ABSTRACT

OBJECTIVE: The aim of the study was to compare national surgical practice patterns of performing apical suspension procedures (ASPs) at the time of hysterectomy for pelvic organ prolapse (POP) before and after the publication of the American College of Obstetricians and Gynecologists (ACOG) 2017 Practice Bulletin on POP.

METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for hysterectomy cases performed for POP indications for the years 2015-2016 and 2018-2019. The primary outcome was the use of ASP at the time of hysterectomy for POP. Secondary outcomes included the use of anterior, posterior, and paravaginal prolapse repair procedures. Multivariable regression analysis was performed to identify factors associated with performing a hysterectomy without an ASP.

RESULTS: A total of 11,336 cases were included, and apical prolapse was the primary POP diagnosis in 86.3% of these cases. There was no statistically significant change in the utilization of ASPs in 2018-2019 compared with 2015-2016 (51.4% vs 49.8%, P = 0.081). Urogynecologists were significantly more likely than general gynecologists to perform ASPs (65.6% vs 37.5%, P < 0.001), which was confirmed on multivariable logistic regression analysis (adjusted odds ratio, 3.257; P < 0.001). The use of concomitant anterior repairs (44.1% vs 39.5%, P < 0.001) and posterior repairs (47.5% vs 41.3%, P < 0.001) increased in the 2018-2019 cohort.

CONCLUSIONS: There was no overall increase in the utilization of concomitant ASPs at the time of hysterectomy done for POP indications despite the 2017 American College of Obstetricians and Gynecologists practice bulletin. Urogynecologists were more likely to perform ASPs than general gynecologists.

ABSTRACT

OBJECTIVE: The primary objective was to evaluate the use of a novel video for enhancing patient knowledge of midurethral sling compared with standard handout.

METHODS: Participants scheduled for midurethral sling were randomized to 1 of 2 preoperative educational interventions, either video or standard handout. The primary outcome was change in knowledge measured via a 15-question questionnaire completed immediately before and after the intervention. Secondary outcomes were knowledge retention, urinary symptoms, decision satisfaction, and regret measured via validated questionnaires at 2 and 6 weeks postoperatively. Data are presented as median (interquartile range) and comparisons between intervention groups made using non-parametric statistics. A sample size of 16 per arm was calculated to detect a 20% effect size.

RESULTS: Thirty-eight participants, 19 per site, were randomized from August 2019 to October 2020 and 37 (97%) completed the primary outcome per protocol. Median age was 51 years (18 years), and there were no significant demographic differences between groups. Participants randomized to video demonstrated greater change in knowledge than those randomized to handout (+8.5 (3) vs +2.0 (4), P < 0.0001). Those randomized to video demonstrated improved 6 week postoperative urinary symptoms (Urogenital Distress Inventory-6, 0.0 [8.3] vs 14.6 [26.0]; P = 0.02; Incontinence Severity Index, 0.0 [2] vs 3.0 [4]; P = 0.005). There were no differences in satisfaction with decision (5.0 [0] video vs 5.0 [0.9] handout; P = 0.48) or decision regret (1.0 [0.5] video vs 1.0 [0.8] handout; P = 0.80) at 6 weeks postoperatively.

CONCLUSIONS: A preoperative educational video improved knowledge and urinary symptoms after midurethral sling compared with a standard handout.

ABSTRACT

OBJECTIVES: This study aimed to evaluate transient urinary retention in women undergoing outpatient midurethral sling placement who received preoperative gabapentin (treated) versus those who did not (untreated). Secondary outcomes included unexpected admission rates, analgesic usage, time to discharge, and pain.

METHODS: This was a retrospective cohort study including women who underwent outpatient midurethral sling placement from 2015 to 2019. Exclusion criteria included suprapubic catheter placement, planned overnight admission, abnormal preoperative postvoid residual volume, and prolonged postoperative catheterization. Logistic regression was performed to evaluate gabapentin usage and urinary retention after adjusting for patient characteristics.

RESULTS: Three hundred two women met the inclusion criteria, with 19.5% experiencing urinary retention after midurethral sling placement. Women older than 65 years were more likely to have urinary retention than those aged 18-65 years (29.8% vs 17.6%, P = 0.054). Of treated participants, 26% had urinary retention versus 18% of untreated participants (P = 0.162). Adjusting for age, parity, pain, operative time, blood loss, sling type, analgesic, scopolamine patch, or hemostatic agent use, treated participants had 72% higher odds of urinary retention (adjusted odds ratio, 1.72; 95% confidence interval, 0.88-3.38; P = 0.113). There was no difference in unexpected admission, analgesic usage, time to discharge, or pain between groups.

CONCLUSIONS: One of 5 women had urinary retention after outpatient midurethral sling placement. Although no statistically significant difference was found in urinary retention between groups, the odds of urinary retention in the treated group were increased. Because there was no difference in pain, analgesic usage, or time to discharge between groups, investigation regarding gabapentin use for outpatient urogynecologic surgery is needed.

ABSTRACT

OBJECTIVE: The objective of our study was to describe differences in commercial patient reviews of women and men urogynecologic surgeons.

MATERIALS AND METHODS: Reviews of surgeons on Healthgrades.com in 4 metropolitan areas were included. Based on the qualitative assessment using qualitative content analysis of major and minor elements, we defined 4 theme categories: global experience, social interaction, technical skills, and ancillary aspects, each embedded with discrete elements. Differences in proportions of mentioned themes as well as quantitative ratings were evaluated by sex with the appropriate statistical tests.

RESULTS: Three hundred sixty-four patient reviews (51% for women surgeons and 49% for men surgeons) were identified for 141 gynecologic surgeons self-identifying as “urogynecologists.” The majority of the cohort (77%) held subspecialty certification in female pelvic medicine and reconstructive surgery. Reviews of women demonstrated a lower mean quantitative “likelihood to recommend” score compared with men (4.0 vs 4.3, P = 0.002) on the 5-point scale. Women received more mention in comfort (52% vs 40%, P = 0.023) and professionalism (19% vs 9%, P = 0.007) themes and less mention with respect to surgical outcomes (28% vs 53%, P < 0.001) and technical skills (5% vs 15%, P = 0.011) compared with men.

CONCLUSIONS: Commercial online patient reviews for urogynecologic surgeons reveal sex bias with women receiving lower scores overall and more comments related to social interaction and fewer comments related to surgical outcomes and technical skill compared with men.
