Abstract Background: It is not known whether modifiable lifestyle factors that predict survival after invasive breast cancer differ by subtype. Methods: We analyzed data for 121,435 women diagnosed with breast cancer from 67 studies in the Breast Cancer Association Consortium with 16,890 deaths (8,554 breast cancer specific) over 10 years. Cox regression was used to estimate associations between risk factors and 10-year all-cause mortality and breast cancer–specific mortality overall, by estrogen receptor (ER) status, and by intrinsic-like subtype. Results: There was no evidence of heterogeneous associations between risk factors and mortality by subtype (Padj > 0.30). The strongest associations were between all-cause mortality and BMI ≥30 versus 18.5–25 kg/m2 [HR (95% confidence interval (CI), 1.19 (1.06–1.34)]; current versus never smoking [1.37 (1.27–1.47)], high versus low physical activity [0.43 (0.21–0.86)], age ≥30 years versus <20 years at first pregnancy [0.79 (0.72–0.86)]; >0–<5 years versus ≥10 years since last full-term birth [1.31 (1.11–1.55)]; ever versus never use of oral contraceptives [0.91 (0.87–0.96)]; ever versus never use of menopausal hormone therapy, including current estrogen–progestin therapy [0.61 (0.54–0.69)]. Similar associations with breast cancer mortality were weaker; for example, 1.11 (1.02–1.21) for current versus never smoking. Conclusions: We confirm associations between modifiable lifestyle factors and 10-year all-cause mortality. There was no strong evidence that associations differed by ER status or intrinsic-like subtype. Impact: Given the large dataset and lack of evidence that associations between modifiable risk factors and 10-year mortality differed by subtype, these associations could be cautiously used in prognostication models to inform patient-centered care.

Background: Folliculotropic mycosis fungoides (FMF) is a variant of cutaneous T-cell lymphoma that has clinical overlap with a variety of inflammatory follicular unit disorders. However, we describe distinctive presentations of FMF with acneiform features that can be diagnostically challenging, leading to diagnostic delay. Objective: To highlight the importance of histopathologic and immunohistochemical evaluation for diagnostic confirmation of presumed inflammatory follicular unit–based disorders that are unusual in presentation or unresponsive to standard therapies. Methods: A cross-sectional retrospective study of 5 consecutive patients with a histopathologic diagnosis of FMF was conducted. The clinical, histopathologic, immunophenotypic, and molecular genetic features of cases are presented. Results: We describe 5 patients with clinical and histopathologic presentations of FMF masquerading as hidradenitis suppurativa, furunculosis, or acne vulgaris (age range 34–66 years, 4:1 female to male). Clinical morphologies included open and closed comedones, inflammatory pustules, papules and nodules, follicular papules with keratotic plugging, cysts, and scarring involving the face, trunk, and intertriginous areas. All patients failed to respond to standard therapies, including topical and oral antibiotics, topical and oral retinoids, or topical corticosteroids, before receiving the diagnosis of FMF. Lesional skin biopsies showed a perifollicular CD4-positive T-lymphocytic infiltrate with pilotropism, intrafollicular mucin deposition, foreign-body granulomatous inflammation, acute inflammation, and follicular epithelial necrosis. None had concurrent systemic mycosis fungoides. Limitations: Small retrospective cohort study. Conclusion: We present these cases to expand the clinical and histopathologic spectrum of FMF that may strikingly resemble acneiform disorders and to highlight the importance of diagnostic reconsideration with histopathologic evaluation.

Abstract Aim The 2018 American Heart Association/American College of Cardiology/Multi-Society Cholesterol Guidelines recommended the addition of non-statins to statin therapy for high-risk secondary prevention patients above a low-density lipoprotein cholesterol (LDL-C) threshold of ≥70 mg/dL (1.8 mmol/L). We compared effectiveness and safety of treatment to achieve lower (<70) vs. higher (≥70 mg/dL) LDL-C among patients receiving intensive lipid-lowering therapy (statins alone or plus ezetimibe or proprotein convertase subtilisin/kexin type 9 inhibitors). Methods and results Eleven randomized controlled trials (130 070 patients), comparing intensive vs. less-intensive lipid-lowering therapy, with follow-up ≥6 months and sample size ≥1000 patients were selected. Meta-analysis was reported as random effects risk ratios (RRs) [95% confidence intervals] and absolute risk differences (ARDs) as incident cases per 1000 person-years. The median LDL-C levels achieved in lower LDL-C vs. higher LDL-C groups were 62 and 103 mg/dL, respectively. At median follow-up of 2 years, the lower LDL-C vs. higher LDL-C group was associated with significant reduction in all-cause mortality [ARD −1.56; RR 0.94 (0.89–1.00)], cardiovascular mortality [ARD −1.49; RR 0.90 (0.81–1.00)], and reduced risk of myocardial infarction, cerebrovascular events, revascularization, and major adverse cardiovascular events (MACE). These benefits were achieved without increasing the risk of incident cancer, diabetes mellitus, or haemorrhagic stroke. All-cause mortality benefit in lower LDL-C group was limited to statin therapy and those with higher baseline LDL-C (≥100 mg/dL). However, the RR reduction in ischaemic and safety endpoints was independent of baseline LDL-C or drug therapy. Conclusion This meta-analysis showed that treatment to achieve LDL-C levels below 70 mg/dL using intensive lipid-lowering therapy can safely reduce the risk of mortality and MACE.

Abstract Chicago Classification v4.0 (CCv4.0) is the updated classification scheme for esophageal motility disorders using metrics from high‐resolution manometry (HRM). Fifty‐two diverse international experts separated into seven working subgroups utilized formal validated methodologies over two‐years to develop CCv4.0. Key updates in CCv.4.0 consist of a more rigorous and expansive HRM protocol that incorporates supine and upright test positions as well as provocative testing, a refined definition of esophagogastric junction (EGJ) outflow obstruction (EGJOO), more stringent diagnostic criteria for ineffective esophageal motility and description of baseline EGJ metrics. Further, the CCv4.0 sought to define motility disorder diagnoses as conclusive and inconclusive based on associated symptoms, and findings on provocative testing as well as supportive testing with barium esophagram with tablet and/or functional lumen imaging probe. These changes attempt to minimize ambiguity in prior iterations of Chicago Classification and provide more standardized and rigorous criteria for patterns of disorders of peristalsis and obstruction at the EGJ.

Abstract The precise characterization of the lobular architecture of the liver has been subject of investigation since the earliest historical publications, but an accurate model to describe the hepatic lobular microanatomy is yet to be proposed. Our aim was to evaluate whether Voronoi diagrams can be used to describe the classic liver lobular architecture. We examined the histology of normal porcine and human livers and analyzed the geometric relationships of various microanatomic structures utilizing digital tools. The Voronoi diagram model described the organization of the hepatic classic lobules with overall accuracy nearly 90% based on known histologic landmarks. We have also designed a Voronoi-based algorithm of hepatic zonation, which also showed an overall zonal accuracy of nearly 90%. Therefore, we have presented evidence that Voronoi diagrams represent the basis of the two-dimensional organization of the normal liver and that this concept may have wide applicability in liver pathology and research.

Objective: To determine whether a bi-directional relationship exists between depression and HF within a single population of individuals receiving primary care services, using longitudinal electronic health records (EHRs). Methods: This retrospective cohort study utilized EHRs for adults who received primary care services within a large healthcare system in 2006. Validated EHR-based algorithms identified 10,649 people with depression (depression cohort) and 5,911 people with HF (HF cohort) between January 1, 2006 and December 31, 2018. Each person with depression or HF was matched 1:1 with an unaffected referent on age, sex, and outpatient service use. Each cohort (with their matched referents) was followed up electronically to identify newly diagnosed HF (in the depression cohort) and depression (in the HF cohort) that occurred after the index diagnosis of depression or HF, respectively. The risks of these outcomes were compared (vs. referents) using marginal Cox proportional hazard models adjusted for 16 comorbid chronic conditions. Results: 2,024 occurrences of newly diagnosed HF were observed in the depression cohort and 944 occurrences of newly diagnosed depression were observed in the HF cohort over approximately 4–6 years of follow-up. People with depression had significantly increased risk for developing newly diagnosed HF (HR 2.08, 95% CI 1.89–2.28) and people with HF had a significantly increased risk of newly diagnosed depression (HR 1.34, 95% CI 1.17–1.54) after adjusting for all 16 comorbid chronic conditions. Conclusion: These results provide evidence of a bi-directional relationship between depression and HF independently of age, sex, and multimorbidity from chronic illnesses.

Abstract Objective To evaluate the efficacy, tolerability, and safety of eptinezumab 100 and 300 mg compared with placebo in patients with the dual diagnosis of chronic migraine (CM) and medication‐overuse headache (MOH). Background Eptinezumab, a humanized monoclonal antibody targeting calcitonin gene‐related peptide, may be effective for treating patients with a dual diagnosis of CM and MOH. Methods PROMISE‐2 (NCT02974153) was a double‐blind, randomized, placebo‐controlled, phase 3 study that comprised a screening visit, a 28‐day pretreatment period, and a 32‐week study duration. Patients in this exploratory analysis of a prespecified subgroup had confirmed diagnoses of both CM and MOH at screening. Patients were randomly assigned to receive intravenous eptinezumab 100, 300 mg, or placebo every 12 weeks. Efficacy outcomes included mean changes from baseline in monthly migraine days (MMDs) during weeks 1–12, migraine responder rates at week 12, and percentages of patients below International Classification of Headache Disorders thresholds for CM and MOH over weeks 1–24. Results There were 431 patients who were diagnosed with CM and MOH as specified in the protocol and received eptinezumab 100 mg ( n = 139), 300 mg ( n = 147), or placebo ( n = 145). During the baseline period, these patients experienced an average of 16.7 migraine days across treatment arms. Over weeks 1–12, eptinezumab‐treated patients experienced greater reductions from baseline in MMDs than placebo patients (100 mg, change from baseline = −8.4, difference from placebo [95% confidence interval (CI)] = −3.0 [−4.56, −1.52], p < 0.0001 vs. placebo; 300 mg, change from baseline = −8.6, difference from placebo [95% CI] = −3.2 [−4.66, −1.78], p < 0.0001 vs. placebo; placebo, −5.4). Compared with placebo, more eptinezumab‐treated patients were ≥50% migraine responders (100 mg, 84/139 [60.4%]; 300 mg, 91/147 [61.9%]; placebo, 50/145 [34.5%]) or ≥75% responders (100 mg, 38/139 [27.3%]; 300 mg, 44/147 [29.9%]; placebo, 21/145 [14.5%]) over weeks 1–12. Therapeutic benefits with eptinezumab were observed from day 1 after dosing, and improvements were sustained with an additional dose. For the full 24‐week treatment period, 71/139 (51.1%), 80/147 (54.4%), and 47/145 (32.4%) of 100, 300 mg, and placebo‐treated patients, respectively, were below CM thresholds, and of the patients who provided sufficient acute medication data, 47/93 (50.5%), 53/107 (49.5%), and 26/96 (27.1%), respectively, were below medication‐overuse thresholds. Conclusions In patients diagnosed with both CM and MOH, eptinezumab treatment resulted in greater reductions in MMDs, higher responder rates, and fewer patients meeting CM and MOH criteria, thus demonstrating the efficacy and clinical utility of eptinezumab in this patient population.

Abstract Background Cutibacterium species are common pathogens in periprosthetic joint infections (PJI). These infections are often treated with β-lactams or clindamycin as monotherapy, or in combination with rifampin. Clinical evidence supporting the value of adding rifampin for treatment of Cutibacterium PJI is lacking. Methods In this multicenter retrospective study, we evaluated patients with Cutibacterium PJI and a minimal follow-up of 12 months. The primary endpoint was clinical success, defined by the absence of infection relapse or new infection. We used Fisher’s exact tests and Cox proportional hazards models to analyze the effect of rifampin and other factors on clinical success after PJI. Results We included 187 patients (72.2% male, median age 67 years) with a median follow-up of 36 months. The surgical intervention was a 2-stage exchange in 95 (50.8%), 1-stage exchange in 51 (27.3%), debridement and implant retention (DAIR) in 34 (18.2%), and explantation without reimplantation in 7 (3.7%) patients. Rifampin was included in the antibiotic regimen in 81 (43.3%) cases. Infection relapse occurred in 28 (15.0%), and new infection in 13 (7.0%) cases. In the time-to-event analysis, DAIR (adjusted hazard ratio [HR] = 2.15, P = .03) and antibiotic treatment over 6 weeks (adjusted HR = 0.29, P = .0002) significantly influenced treatment failure. We observed a tentative evidence for a beneficial effect of adding rifampin to the antibiotic treatment—though not statistically significant for treatment failure (adjusted HR = 0.5, P = .07) and not for relapses (adjusted HR = 0.5, P = .10). Conclusions We conclude that a rifampin combination is not markedly superior in Cutibacterium PJI, but a dedicated prospective multicenter study is needed.

AbstractBackgroundAlzheimer’s disease (AD) prevention trials aim to intervene prior to significant neuronal loss, brain damage, and symptom onset to delay or slow cognitive decline. In dominantly inherited AD (DIAD), mutation carriers develop symptomatic AD at predictable ages with near 100% penetrance. In 2012, the Dominantly Inherited Alzheimer Network Trials Unit Adaptive Prevention Trial (DIAN‐TU APT) platform launched a double‐blind, randomized, placebo‐controlled, parallel group trial of two anti‐amyloid‐beta monoclonal antibodies with two different antigenic targets, gantenerumab and solanezumab (NCT01760005). The DIAN‐TU scientific development, implementation of the first AD prevention trial, trial challenges and opportunities, including dose escalation, and top‐line results will be presented.MethodDIAN was established in 2008 in response to a call from the National Institute of Aging to establish a network to study DIAD and enable future clinical trials. Successive breakthroughs in understanding disease processes enabled the launch of the DIAN‐TU adaptive prevention trial, a global adaptive platform trial supporting testing multiple drugs in parallel. The DIAN‐TU partners include patients and families at risk for DIAD, global academic researchers, the NIH, Alzheimer’s Association, philanthropic supporters, the DIAN‐TU Pharma Consortium, and pharmaceutical companies with drugs being tested. Important milestones include developing a platform to enable a comprehensive efficient treatment trial for this rare population, adding tau PET as part of AMP AD, adapting dosing mid‐trial and extending the original biomarker trial to continue randomized dosing to test a cognitive endpoint until the last patient reaches 4 years, developing a disease progression statistical model and inclusion of DIAN observational data to increase the power to determine drug effects.ResultThe primary and key secondary outcomes of the DIAN‐TU trial will be presented for each therapy in the context of targeting amyloid‐beta at pre‐clinical and clinically symptomatic stages of disease.ConclusionThese results inform about AD hypotheses, timing of treatment and the prospect of slowing, or preventing AD in DIAD and sporadic AD.
