Published: March 2022

Purpose The aim of this study was to investigate the role of functionally significant loci of the matrix metalloproteinases genes 1, 3, 9 ( MMP1, MMP3, and MMP9) in the development of primary open-angle glaucoma (POAG) in Caucasians of the Central region of Russia. Methods In total 604 participants were recruited for the study, including 208 patients with POAG and 396 healthy controls. They were genotyped at eight single nucleotide polymorphisms (SNPs) of the three MMP genes. The association was analyzed using logistic and log-linear regression. POAG-associated loci and their proxies were in silico assessed for their functional prediction. Results Variant allele G*rs2250889 of MMP9 was significantly associated with higher risk of POAG (ORcov = 1.57–1.71). Haplotype CCA [rs3918242-rs3918249-rs17576] of the MMP9 gene was associated with lower risk of POAG (ORcov = 0.33). Allele А*rs3787268 of MMP9 was associated with the low intraocular pressure in the POAG patients (βcov = −0.176 - −0.272), and so were haplotypes AA [rs17576-rs3787268] (βcov = −0.577) and AAC [rs17576-rs3787268- rs2250889] (βcov = −0.742) of the same gene, whereas allele 2G*rs1799750 of MMP1 was associated with the earlier onset of the disease (βcov = −0.112 - −0.218). In silico analysis of the polymorphisms suggested the functionality of POAG-associated SNPs and their proxies (epigenetic potential, expression and alternative splicing effects for several genes). Conclusions The MMP9 gene polymorphisms are associated with POAG and intraocular pressure in POAG patients; rs1799750 of MMP1 was associated with the earlier age of manifestation of the disease symptoms.

Purpose: Women with lobular carcinoma in-situ (LCIS) have an increased risk for developing breast cancer (BC) compared with the general population. However, little is known about the clinical implication of diagnosing LCIS concurrently with an invasive breast cancer. We aimed to define the rate of LCIS diagnosed concurrently with an invasive breast cancer and investigate the risk of contralateral breast cancer (CBC) during survivorship care. Materials and methods: A single center retrospective review over 6 years identified women with stage I-III BC who underwent lumpectomy or unilateral mastectomy. Patients with or without concurrent LCIS were compared using Chi-squared analyses to assess for differences in clinicopathologic factors and risk of future CBC (including invasive and in-situ disease). Results: Of 1808 patients, 16.6% (n = 301) had LCIS concurrent with their index breast cancer. Patients with LCIS had a higher rate of subsequent CBC development than those without LCIS (3.3% versus 1.0%, P = .004). The risk ratio for patients with LCIS developing subsequent CBC compared with those without LCIS was 3.3 (95% confidence interval [CI]: 1.5-7.3). Conclusions: Patients with LCIS diagnosed concurrently with their index breast cancer at surgery are at higher risk for subsequent CBC than those without LCIS. The evidence from this study suggest that it may be appropriate for women with LCIS diagnosed alongside an index breast cancer to consider on-going high-risk screening during survivorship care.

Published: March 2022

Background Acute ischemic stroke (AIS) is a common and fatal complication of infective endocarditis (IE); however, there is a lack of understanding regarding treatment efficacy. This systematic review aimed to evaluate the safety and efficacy of intravenous thrombolysis (IVT) and endovascular thrombectomy (EVT) in IE patients experiencing AIS. Objectives The aim of this study was to perform a systematic review investigating the outcomes of AIS in IE patients receiving IVT and/or EVT as a treatment method and to evaluate the safety and efficacy of these methods of reperfusion therapy. Design A systematic review in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines was conducted. Data Sources and Methods The EMBASE, Cochrane, and PubMed databases were searched for literature published between 2005 and 2021 investigating outcomes of reperfusion therapy post-AIS in IE and non-IE patients. Descriptive statistics were used to describe the overall frequency of clinical outcomes, and groupwise comparisons were performed using Fisher’s exact test to assess the significance of groupwise differences. Results Three studies were finally included in the systematic review. A total of 13.5% of IE patients compared to 37% of non-IE patients achieved a good functional outcome (modified Rankin Scale score≤ 2) ( P < .001). Furthermore, a larger percentage of the IE cohort achieved good functional outcomes after EVT (22.0%) compared to IVT (10.4%) ( P = .013). The IE cohort also had a higher 3-month postreperfusion mortality rate (48.8%) compared to the non-IE cohort (24.9%) ( P < .001). The rate of intracranial hemorrhage (ICH) postreperfusion was also significantly higher in the IE cohort (23.5%) than in the non-IE cohort (6.5%) ( P < .001). Conclusion AIS patients with IE, treated with IVT, EVT, or a combination of the two, experience worse clinical and safety outcomes than non-IE patients. EVT yielded better functional outcomes, albeit with higher postreperfusion ICH rates, than IVT.

Published: March 2022

Purpose: Although the size of drug-coated balloons (DCBs) is determined according to the vessel diameter during femoropopliteal (FP)-endovascular therapy (EVT), the measurements of the vessel diameter vary among modalities and its definitions. The aim of this study was to reveal whether the DCB size fitting (1) angiographically-measured lumen diameter (Angio-lumen size), (2) intravascular ultrasound (IVUS)-measured lumen diameter (IVUS-lumen size), or (3) IVUS-measured external elastic membrane (EEM) diameter (IVUS-EEM size) would be beneficial in restenosis occurrence. Materials and Methods: This retrospective, single-center study included 231 de novo FP lesions in 165 patients with peripheral artery disease treated with IN.PACT Admiral DCB under IVUS evaluation. The reference vessel diameter was evaluated as the lumen or EEM diameter at the healthy site distal to the lesion. We retrospectively determined whether the DCB size was close to (ie, equal to or different by <0.5 mm from) Angio-lumen size, IVUS-lumen size, and IVUS-EEM size. The association of the size of DCB with restenosis risk was investigated. Results: The mean lesion length was 13 ± 9 cm and the prevalence of chronic total occlusion was 18%. During a mean follow-up period of 17 ± 9 months, restenosis occurred in 26% of lesions. Lesions treated with a DCB of IVUS-EEM size had a lower 2 year restenosis rate than those treated with a DCB over/under IVUS-EEM size (19.7 ± 5.7% vs 34.5 ± 4.7%, p=0.02 by the log-rank test), while the restenosis rate was not significantly different between DCBs of Angio-lumen size or IVUS-lumen size and those over/under the size (both p>0.05). The multivariate Cox regression analysis revealed that DCBs of IVUS-EEM size were independently associated with a reduced risk of restenosis (adjusted hazard ratio 0.50; 95% confidence interval 0.27–0.95; p=0.03). Conclusion: The DCBs of IVUS-EEM size, but not of Angio-lumen size or IVUS-lumen size, were associated with a reduced risk of restenosis after FP-EVT. Determining the DCB size according to IVUS-evaluated EEM diameter would be potentially beneficial in restenosis occurrence.

Published: March 2022

Objective: Symptomatic abdominal aortic aneurysms (sAAA) are considered surgically urgent. Recent data suggest delaying surgery allows for medical optimization without affecting outcomes. We investigated the association of the hospital day of surgery with 30 day outcomes. Methods: Patients with infrarenal sAAA undergoing endovascular aortic repair (EVAR) between 2011 and 2018 in the American College of Surgeons National Surgery Quality Improvement Project database were included. The primary outcome was 30 day mortality. Additional outcomes included myocardial infarction, pulmonary complications, length of stay, and discharge disposition. Days-to-surgery were classified as the day of presentation (D0), day 1, day 2, days 3 and 4, days 5 to 7 (D5), and day 8 or more (D8). Results: A total of 804 patients were identified. D8 patients had higher proportions of dyspnea on exertion, chronic obstructive pulmonary disease, congestive heart failure, and history of dialysis. D0 surgery appeared protective of mortality (odds ratio [OR] 0.34, p=0.0132). Each additional day increased the mortality risk (OR 1.23, p<0.001) although not within the first 4 days. There was increased mortality for patients having surgery at D5 (7.7%) and D8 (23.8%) compared with repair earlier (1%–4%, p=0.03). Bivariable analysis revealed no significant differences in secondary outcomes. Multivariable modeling revealed increased mortality for D8 versus D0 (adjusted OR of 6.8, 95% confidence interval 1.7–26.5). Conclusions: While D0 appears to have the lowest risk of mortality, EVAR for sAAA up to 4 days may not be associated with increased mortality. Further research should determine delay etiologies and whether they improve operative planning and optimization without impacting morbidity and mortality.

Published: March 2022

Background: This article compares the rates and time-to-development of new-onset Dupuytren disease in patients with trigger finger treated by steroid injection, surgical release, or both. Methods: PearlDiver’s Mariner 30 database was queried to identify patients with trigger finger between January 2010 and June 2019. One-to-one exact matching based on baseline patient demographics allowed us to create 4 identical groups defined by the type of trigger finger intervention received. Results: The matched population analyzed in this study consisted of 85 944 patients who were equally represented in the steroid injection cohort (n = 21 486, 25.00%), surgical release cohort (n = 21 486, 25.00%), steroids prior to surgery cohort (n = 21 486, 25.00%), and no intervention (control) cohort (n = 21 486, 25.00%). A new Dupuytren diagnosis after trigger finger treatment occurred in 1 in 128 patients overall, 1 in 156 patients treated with steroid injection, and 1 in 126 patients treated with surgical release. Trigger fingers treated by steroid injection only had the lowest rates of Dupuytren disease overall (n = 137, 0.64%, P = .0424) and treatment with fasciectomy (n = 14, 0.07%, P < .0005). In all, 171 patients in the surgery cohort developed Dupuytren disease 1 year after undergoing surgical trigger finger release. Furthermore, this cohort had the highest rates of fasciectomy (n = 55, 0.26%, P < .0005) and the lowest rates of no intervention (n = 103, 0.48%, P = .0471). Trigger fingers managed by surgical release developed Dupuytren disease (mean, 56.11 days; SD, 80.93 days, log-rank P = .02) and underwent fasciectomy (mean, 49.74 days; SD, 62.27 days; log-rank P < .0005) more quickly than all other cohorts. Conclusions: Patients solely undergoing surgical release of their trigger finger had significantly higher odds and expedited rate of developing new-onset Dupuytren disease overall and undergoing subsequent treatment by fasciectomy compared with trigger fingers managed by other interventions.

Background There is no consensus regarding optimal antiplatelet regimen for emergent carotid stenting during stroke thrombectomy. We aimed to assess the safety and efficacy of an aggressive periprocedural antiplatelet strategy focused on preserving stent patency, in comparison with conservative antiplatelet strategy consisting of aspirin monotherapy. Materials and Methods Retrospective review of a prospectively collected database in a comprehensive stroke center, including all cases of emergent carotid stenting for tandem lesions stroke between 01.03.2012–01.06.2021. Aggressive antiplatelet strategy consisted of dual antiplatelet therapy (DAPT) with aspirin and clopidogrel loading doses, with added intravenous (IV) tirofiban if in-stent thrombosis was observed during thrombectomy. Clinical and radiological outcomes were compared between conservative and aggressive antiplatelet treatment groups using inverse probability of treatment weighting (IPTW) analysis based on propensity scores. Results We included 132 cases (76.5% atheroma, 22.7% dissection, 0.7% carotid web). Forty-five patients (34%) cases received conservative antiplatelet therapy. The remaining 87 (65.9%) received aggressive antiplatelet therapy: 66 (75.8%) treated with DAPT, 21 (24.1%) with DAPT and tirofiban. Periprocedural heparin was avoided in all cases. In adjusted analysis of the weighted samples, aggressive antiplatelet strategy was associated with improved carotid stent patency (aOR 0.23, 95% CI 0.07–0.80, p = 0.021), higher proportion of moderate clinical outcome (mRS ≤ 3, aOR 2.72, 95% CI 1.01–7.30, p = 0.04), with no significant differences in mortality and hemorrhagic transformation (HT) rates. Conclusions In this retrospective study, aggressive periprocedural antiplatelet strategy led to improved stent patency and clinical outcomes, without increased HT. Further prospective randomized research is warranted to identify the optimal combination of antiplatelet agents for emergent carotid stenting in the setting of acute stroke.

Published: March 2022

This study describes a new ultrasound-guided surgical technique for aponeurotomy and interphalangeal joint capsular release in patients with Dupuytren’s disease and analyses the clinical outcomes. We carried out a retrospective review of 70 digits in 35 patients who underwent ultrasound-guided aponeurotomy and interphalangeal joint capsular release, with a minimum follow-up of 2 years. The primary outcome was the correction of the deformity and the QuickDASH questionnaire score after surgery and at 1 and 2 years. The secondary outcome was the presence of residual contracture immediately after surgery. The mean QuickDASH score fell from 28 before surgery to 14 after surgery. A significant decrease of −63° was observed for the global contracture, −35° the metacarpophalangeal joint contracture and −28° for the proximal interphalangeal joint contracture. Ultrasound-guided aponeurotomy and interphalangeal joint capsular and palmar plate releases are highly accurate and safe. Level of evidence: IV

Published: March 2022

Living on a high-fat, high-calorie, and high-protein diet for a long period may compromise human immunity due to the long-term accumulation of free radicals and plasma lipids. The antioxidant and lipid-lowering compounds (ie polyphenols and vitamin E) in Camellia oil help to decrease the risk of numerous ailments, including cardiovascular disease (CVD), and obesity. The aims of this study were to study the hypolipidemic and antioxidant effects of Camellia oil in high-fat-fed rats and to promote the high-value use of camellia resources. The high-fat-fed rats were administrated with 2.5, 7.5, and 15 mL/kg BW Camellia oil (Camellia oil group), and 10 mg/kg BW atorvastatin (atorvastatin group), respectively, and compared with a model group (only fed with high fat) and a control group (fed with basal diet). Several parameters were measured, including (1) body weight (BW), liver-to-BW ratio; (2) plasma total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C); and (3) alanine aminotransferase (ALT), alanine aminotransferase (AST), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activity, model driven architecture (MDA) content, lipid metabolism-related genes, and antioxidant-related genes in liver tissue. Compared with the model group, the high-fat-fed rats in the Camellia oil and atorvastatin group had significantly lower BW and liver-to-BW ratio ( P < .01), plasma TC, TG, and LDL-C levels and ALT and AST activities, but higher HDL-C levels. The relative expressions of ACAT1, DGAT2, FAS, and SREBP genes were significantly reduced in the Camellia oil and atorvastatin groups, while the relative expressions of LCAT, UCP2, MCD, and CPT-1 genes were significantly increased. The rats in the Camellia oil group showed significantly higher SOD and GSH-Px activities, significantly lower MDA content, and significantly higher relative expression of antioxidant genes (eg SOD1, GPx1, CAT, and Gclm). Thus, atorvastatin and Camellia oil exhibited significant hypolipidemic and antioxidant effects, which were better at a dose of 7.5 mL/kg (BW) of Camellia oil. Therefore, Camellia oil becomes a potential new natural resource for future research and development of antioxidant and hypolipidemic drugs, nutraceuticals, and additives.

Published: March 2022

Background The management of symptomatic osteochondral lesions of the talus (OLTs) previously treated with arthroscopy is controversial. Minimal data exist on the role for repeat arthroscopy. Here, we describe our experience with repeat arthroscopy and microfracture for symptomatic OLTs. Methods Our database was queried over an 8-year period to identify patients undergoing repeat arthroscopy and microfracture as treatment for symptomatic OLTs. Phone surveys were conducted to assess residual pain, patient satisfaction, and need for subsequent surgery. We compared patient outcomes based on the size of their OLT (small lesions ≤150 mm2, large >150 mm2) and the presence or absence of subchondral cysts. Results We identified 14 patients who underwent repeat arthroscopy and microfracture for symptomatic OLTs. Patients reported reasonable satisfaction (7.6 ± 3.5 out of 10) but moderate residual pain (4.7 ± 3.4 out of 10) at midterm follow-up (5.1 ± 2.9 years). In total, 21% (3/14) of patients had undergone subsequent surgery. Patients with small (n = 5) and large OLTs (n = 9) had similar postoperative pain scores (4.2 ± 4.1 vs 4.9 ± 3.2) and postoperative satisfaction levels (6.4 ± 4.9 vs 8.3 ± 2.5). Conclusion At midterm follow-up, repeat arthroscopy for symptomatic OLTs demonstrated reasonable satisfaction but moderate residual pain. Lesion size or presence of subchondral cysts did not affect outcome, but our sample size was likely too small to detect statistically significant differences. These data show that repeat ankle arthroscopy can be performed safely with modest outcomes, and we hope that this report aids in managing patient expectations. Level of Evidence: Level IV Case Series

Published: March 2022

Background The growing popularity of collecting self-generated health and lifestyle data presents a valuable opportunity to develop our understanding of long-term health conditions and improve care. Barriers remain to the effective sharing of health and lifestyle data by those living with long-term health conditions which include beliefs around concepts of Trust, Identity, Privacy and Security, experiences of stigma, perceptions of risk and information sensitivity. Method We surveyed 250 UK adults who reported living with a range of long-term health conditions. We recorded data to assess self-reported behaviours, experiences, attitudes and motivations relevant to sharing self-generated health and lifestyle data. We also asked participants about their beliefs about Trust, Identity, Privacy and Security, stigma, and perceptions of risk and information sensitivity regarding their health and lifestyle data. Results Three-quarters of our sample reported recording information about their health and lifestyle on a daily basis. However, two-thirds reported never or rarely sharing this information with others. Trust, Identity, Privacy and Security concerns were considered to be ‘very important’ by those with long-term health conditions when deciding whether or not to share self-generated health and lifestyle data with others, with security concerns considered most important. Of those living with a long-term health condition, 58% reported experiencing stigma associated with their condition. The greatest perceived risk from sharing with others was the potential for future harm to their social relationships. Conclusions Our findings suggest that, in order for health professionals and researchers to benefit from the increased prevalence of self-generated health and lifestyle data, more can be done to address security concerns and to understand perceived risks associated with data sharing. Digital platforms aimed at facilitating the sharing of self-generated health and lifestyle data may look to highlight security features, enable users to control the sharing of certain information types, and emphasise the practical benefits to users of sharing health and lifestyle data with others.
