Background: Non-surgical rhinoplasty with hyaluronic acid (HA) filler is a three-dimensional reshaping technique that achieves tissue enhancement by placing HA deep to nasal skin. Due to its unique rheology, Restylane® Lyft (HA-L, Galderma, Uppsala, Sweden) may be particularly well-suited for injection rhinoplasty, as it has high gel firmness (G’) for strong structural support with minimal integration propensity. Methods: A prospective clinical trial was conducted to evaluate HA-L use for non-surgical rhinoplasty. Thirty-three females were observed over eight months, using the following schedule: Visit 1 = Baseline/Treatment 1; Visit 2 = Optional touch up (Week 2); Visits 3–6 = Follow-ups (Months 1,3,6,8). The primary endpoint was subject improvement at Month 1 assessed by a blinded evaluator using the Global Aesthetic Improvement Scale (GAIS). Subject satisfaction and adverse events (AEs) were also evaluated. Results: A deep, periosteal injection using a bolus technique and 0.34 cc of HA-L was most often used. Seven cases of positive aspiration occurred in 167 injection points (4.19%), among 6/33 (18.18%) subjects. Based on the GAIS, 100% of subjects met the primary endpoint. Subject satisfaction was maximal at Month 1 (100%) and largely maintained at Month 8 (78.57%). Besides expected injection-related AEs (eg, ecchymosis, erythema), immediate AEs during/following treatment were limited to presyncopal symptoms [5/33 subjects (15.15%)]. Importantly, no cases of ischemia were observed. Subject-reported AEs (eg, swelling, erythema, pain) dissipated within 2 to 7 days. Conclusion: Given the technical nature of this technique, HA-L may be well-suited for injection rhinoplasty, due to its strong safety and efficacy profile. Level of Evidence: Level III: Evidence obtained from well-designed cohort study.

Background Flow diverter treatment may inevitably require jailing of the branch vessels. While the patency of covered branch arteries and associated safety risks have been a topic of substantial interest, the question of whether the characteristics of branch vessels affect flow diversion's efficacy remains unanswered. In this study, we aimed to assess the impact of branch arteries on the efficacy of endoluminal flow diverters, specifically focusing on posterior communicating artery (Pcomm) aneurysms. Methods Following PRISMA guidelines, we systematically searched the MEDLINE, EMBASE, Scopus, Web of Science, and Cochrane databases with predefined keywords. Studies providing data for flow diversion outcomes in Pcomm aneurysms were included. Outcomes of interest included complete and adequate aneurysm obliteration, ischemic and hemorrhagic complications, and Pcomm occlusion in the follow-up period. A random or fixed effects model was used to calculate the odds ratios (ORs) and pooled event rates with their corresponding confidence intervals (CI). Results The overall complete and adequate aneurysm occlusion rates were 72.25% (95% CI: 64.46–78.88%) and 88.37% (95% CI: 84.33–92.6), respectively. Fetal-type Pcomm aneurysms had significantly lower complete aneurysm occlusion rates than the nonfetal-type Pcomm aneurysms (OR: 0.12, 95% CI: 0.05–0.29). Overall ischemic and hemorrhagic complication rates were 2.62% (95% CI = 0.71–5.32) and 0.71% (95% CI: 0–2.24), respectively. There were no significant associations between Pcomm morphology and complications (OR: 3.61, 95% CI = 0.42–31.06 for ischemic complications and OR: 2.31, 95% CI = 0.36–14.6 for hemorrhage). Overall Pcomm occlusion rate was 32.04% (95% CI = 19.96–47.13), and the Pcomm patency was significantly lower in nonfetal-type Pcomm aneurysms (OR: 0.10, 95% CI = 0.02–0.44). Conclusion Our meta-analysis suggests that flow diversion is a safe treatment option for Pcomm aneurysms, regardless of fetal-type Pcomm morphology. However, on the other hand, our findings indicate that Pcomm anatomy or the presence of jailed large branches can affect the efficacy of flow diverter treatment.

ImportanceSyncope is the most powerful predictor for subsequent life-threatening events (LTEs) in patients with congenital long QT syndrome (LQTS). Whether distinct syncope triggers are associated with differential subsequent risk of LTEs is unknown.ObjectiveTo evaluate the association between adrenergic (AD)– and nonadrenergic (non–AD)-triggered syncopal events and the risk of subsequent LTEs in patients with LQT types 1 to 3 (LQT1-3).Design, Setting, and ParticipantsThis retrospective cohort study included data from 5 international LQTS registries (Rochester, New York; the Mayo Clinic, Rochester, Minnesota; Israel, the Netherlands, and Japan). The study population comprised 2938 patients with genetically confirmed LQT1, LQT2, or LQT3 stemming from a single LQTS-causative variant. Patients were enrolled from July 1979 to July 2021.ExposuresSyncope by AD and non-AD triggers.Main Outcomes and MeasuresThe primary end point was the first occurrence of an LTE. Multivariate Cox regression was used to determine the association of AD- or non–AD-triggered syncope on the risk of subsequent LTE by genotype. Separate analysis was performed in patients with β-blockers.ResultsA total of 2938 patients were included (mean [SD] age at enrollment, 29 [7] years; 1645 [56%] female). In 1331 patients with LQT1, a first syncope occurred in 365 (27%) and was induced mostly with AD triggers (243 [67%]). Syncope preceded 43 subsequent LTEs (68%). Syncopal episodes associated with AD triggers were associated with the highest risk of subsequent LTE (hazard ratio [HR], 7.61; 95% CI, 4.18-14.20; P < .001), whereas the risk associated with syncopal events due to non-AD triggers was statistically nonsignificant (HR, 1.50; 95% CI, 0.21-4.77; P = .97). In 1106 patients with LQT2, a first syncope occurred in 283 (26%) and was associated with AD and non-AD triggers in 106 (37%) and 177 (63%), respectively. Syncope preceded 55 LTEs (56%). Both AD- and non–AD-triggered syncope were associated with a greater than 3-fold increased risk of subsequent LTE (HR, 3.07; 95% CI, 1.66-5.67; P ≤ .001 and HR, 3.45, 95% CI, 1.96-6.06; P ≤ .001, respectively). In contrast, in 501 patients with LQT3, LTE was preceded by a syncopal episode in 7 (12%). In patients with LQT1 and LQT2, treatment with β-blockers following a syncopal event was associated with a significant reduction in the risk of subsequent LTEs. The rate of breakthrough events during treatment with β-blockers was significantly higher among those treated with selective agents vs nonselective agents.Conclusion and RelevanceIn this study, trigger-specific syncope in LQTS patients was associated with differential risk of subsequent LTE and response to β-blocker therapy.

ImportanceBreast cancer–related lymphedema (BCRL) is a common complication of axillary lymph node dissection (ALND) but can also develop after sentinel lymph node biopsy (SLNB). Several models have been developed to predict the risk of disease development before and after surgery; however, these models have shortcomings that include the omission of race, inclusion of variables that are not readily available to patients, low sensitivity or specificity, and lack of risk assessment for patients treated with SLNB.ObjectiveTo create simple and accurate prediction models for BCRL that can be used to estimate preoperative or postoperative risk.Design, Setting, and ParticipantsIn this prognostic study, women with breast cancer who underwent ALND or SLNB from 1999 to 2020 at Memorial Sloan Kettering Cancer Center and the Mayo Clinic were included. Data were analyzed from September to December 2022.Main Outcomes and MeasuresDiagnosis of lymphedema based on measurements. Two predictive models were formulated via logistic regression: a preoperative model (model 1) and a postoperative model (model 2). Model 1 was externally validated using a cohort of 34 438 patients with an International Classification of Diseases diagnosis of breast cancer.ResultsOf 1882 included patients, all were female, and the mean (SD) age was 55.6 (12.2) years; 80 patients (4.3%) were Asian, 190 (10.1%) were Black, 1558 (82.8%) were White, and 54 (2.9%) were another race (including American Indian and Alaska Native, other race, patient refused to disclose, or unknown). A total of 218 patients (11.6%) were diagnosed with BCRL at a mean (SD) follow-up of 3.9 (1.8) years. The BCRL rate was significantly higher among Black women (42 of 190 [22.1%]) compared with all other races (Asian, 10 of 80 [12.5%]; White, 158 of 1558 [10.1%]; other race, 8 of 54 [14.8%]; P < .001). Model 1 included age, weight, height, race, ALND/SLNB status, any radiation therapy, and any chemotherapy. Model 2 included age, weight, race, ALND/SLNB status, any chemotherapy, and patient-reported arm swelling. Accuracy was 73.0% for model 1 (sensitivity, 76.6%; specificity, 72.5%; area under the receiver operating characteristic curve [AUC], 0.78; 95% CI, 0.75-0.81) at a cutoff of 0.18, and accuracy was 81.1% for model 2 (sensitivity, 78.0%; specificity, 81.5%; AUC, 0.86; 95% CI, 0.83-0.88) at a cutoff of 0.10. Both models demonstrated high AUCs on external (model 1: 0.75; 95% CI, 0.74-0.76) or internal (model 2: 0.82; 95% CI, 0.79-0.85) validation.Conclusions and RelevanceIn this study, preoperative and postoperative prediction models for BCRL were highly accurate and clinically relevant tools comprised of accessible inputs and underscored the effects of racial differences on BCRL risk. The preoperative model identified high-risk patients who require close monitoring or preventative measures. The postoperative model can be used for screening of high-risk patients, thus decreasing the need for frequent clinic visits and arm volume measurements.

Objective: The aim of this research was to evaluate intraoperative visual detection of endometriosis compared to final histopathologic diagnosis based on lesion type. Materials and Methods: This prospective clinical study at a tertiary-care, academic medical center involved 77 patients who had surgery by high-volume endometriosis surgeons for suspected endometriosis. Pelvic peritonectomy was performed with documentation of visual presence or absence of endometriosis and lesion type. Powder burn lesions were defined as typical lesions. White scarring, clear vesicles, red flame, and peritoneal pockets were defined as atypical lesions. Results: Of 1069 peritoneal specimens, there was visual detection of endometriosis in 352 (32.93%). Endometriosis was confirmed on histopathologic evaluation of: powder-burn, 65.8%; white scarring, 51.6%; clear vesicles, 45.7%; red-flame, 39.1%; and peritoneal pockets, 28.9% ( p = 0.003). Additionally, 11.3% of specimens with no visible endometriosis demonstrated a positive histopathologic diagnosis. Overall sensitivity was 68.36%; specificity was 78.15%; positive predictive value (PPV) was 49.72%; and negative predictive value was 88.66%. All lesions had high specificity (powder-burn, 96.20%; white scarring, 91.34%; clear vesicles; 92.54%; red-flame, 97.84%; and peritoneal pockets; 95.91%). PPV depended on lesion type (powder-burn, 65.75%; white scarring, 51.61 %; clear vesicles, 45.74%; red-flame, 39.13% peritoneal pockets, 28.95%). Conclusions: Visual detection of endometriosis during surgical evaluation is not reliable. The potential for atypical-lesion appearance and disease not macroscopically visible suggests a role for complete pelvic peritonectomy. (J GYNECOL SURG 39:235)

Sequencing is increasingly used for infective endocarditis (IE) diagnosis. Here, the performance of 16S rRNA gene PCR/sequencing of heart valves utilized in routine clinical practice was compared with conventional IE diagnostics.

Abstract Background Patients with ulcerative colitis (UC) or Crohn’s disease (CD) are at increased risk of herpes zoster (HZ); however, relevant cost and healthcare resource utilization (HCRU) data are limited. Methods We estimated HCRU (hospitalization, emergency department [ED], and outpatient visits) and costs in patients with UC or CD, with and without HZ, using administrative claims data (October 2015–February 2020). HCRU and costs (2020 US dollars) were compared at 1 month, 1 quarter, and 1 year after the index date, using propensity score adjustment and generalized linear models. Results In total, 20 948 patients were included: UC+/HZ+ (n = 431), UC+/HZ– (n = 10 285), CD+/HZ+ (n = 435), and CD+/HZ– (n = 9797). Patients with HZ had higher all-cause HCRU rates and all-cause total healthcare costs relative to those without HZ. In the first month, adjusted incidence rate ratios (aIRRs) for hospitalizations and ED visits for patients with UC and HZ compared with UC alone were 2.87 (95% confidence interval [CI], 1.93–4.27) and 2.66 (95% CI,1.74–4.05), respectively; for those with CD and HZ, aIRRs were 3.34 (95% CI, 2.38–4.70) and 3.31 (95% CI, 2.32–4.71), respectively, compared with CD alone (all P < .001). Adjusted cost differences in UC and CD cohorts with HZ over the first month were $2189 and $3774, respectively, chiefly driven by higher inpatient costs. The incremental impact on HCRU and costs in cohorts with HZ predominantly occurred during the first quarter following diagnosis. Conclusions HZ is associated with increased HCRU and costs in patients with UC and CD, especially shortly after diagnosis.

AbstractBackgroundPrimary‐progressive multiple sclerosis (PPMS) and relapsing‐remitting multiple sclerosis (RRMS) are two frequent multiple sclerosis (MS) subtypes that involve 10%–15% of patients. PPMS progresses slowly and is diagnosed later in life. Both subtypes are influenced by genetic and environmental factors such as smoking, obesity, and vitamin D insufficiency. Although there is no cure, ocrelizumab can reduce symptoms and delay disease development. RRMS is an autoimmune disease that causes inflammation, demyelination, and disability. Early detection, therapy, and lifestyle changes are critical. This study delves into genetics, immunology, biomarkers, neuroimaging, and the usefulness of ocrelizumab in the treatment of refractory patients of PPMS.MethodIn search of published literature providing up‐to‐date information on PPMS and RRMS, this review conducted numerous searches in databases such as PubMed, Google Scholar, MEDLINE, and Scopus. We looked into genetics, immunology, biomarkers, current breakthroughs in neuroimaging, and the role of ocrelizumab in refractory cases.ResultsOur comprehensive analysis found considerable advances in genetics, immunology, biomarkers, neuroimaging, and the efficacy of ocrelizumab in the treatment of refractory patients.ConclusionEarly detection, timely intervention, and the adoption of lifestyle modifications play pivotal roles in enhancing treatment outcomes. Notably, ocrelizumab has demonstrated potential in symptom control and mitigating the rate of disease advancement, further underscoring its clinical significance in the management of MS.
