Background: In the busy world of cardiovascular medicine, abstracts may be the only part of a publication that clinicians read. Therefore, it is critical for abstracts to accurately reflect article content. The extended CONSORT (Consolidated Standards of Reporting Trials) Statement for Abstracts was developed to ensure high abstract quality. However, it is unknown how often adherence to CONSORT guidelines occurs among cardiovascular journals. Methods and Results: We searched MEDLINE for randomized controlled trials published in 3 major cardiovascular journals ( Circulation, Journal of the American College of Cardiology , and European Heart Journal ) from 2011 to 2017. Post hoc, interim, and cost-effective analyses of randomized controlled trials were excluded. Two independent investigators extracted the data using a prespecified data collection form and a third investigator adjudicated the data. The primary outcome was frequency of subcategory adherence to CONSORT guidelines. A total of 478 abstracts were included in the analysis. Approximately half of the abstracts (53%; 255/478; 95% CI, 49%–57%) identified the article as randomized in the title. All abstracts detailed the interventions for both study groups (100%) and 81% (95% CI, 78%–85%) reported trial registration. Methodological quality reporting was relatively low: 9% (45/478; 95% CI, 6%–12%) described participant eligibility criteria with settings for data collection, 43% (204/478; 95% CI, 39%–47%) reported details of blinding, and <1% (4/478; 95% CI, 0%–2%) reported allocation concealment. Approximately 60% (301/478; 95% CI, 59%–67%) of the included abstracts provided primary outcome results while 55% (262/478; 95% CI, 51%–60%) reported harms or adverse effects. Conclusions: There is a high prevalence of nonadherence to CONSORT guidelines among leading cardiovascular journals. Efforts by editors, authors, and reviewers should be made to increase adherence and promote transparent and unbiased presentation of study results.

AbstractIntroductionAdenomyosis is a benign uterine disease where endometrial glands and stroma are found within the myometrium surrounded by an area of hypertrophic myometrium. Symptomatology includes heavy menstrual bleeding and pelvic pain. The pathogenesis of adenomyosis is not known; however, animal models have shown increased uterine concentration of prolactin as a risk factor. Prolactin acts as a smooth muscle cell mitogen. If prolactin is central to adenomyosis pathogenesis, reducing uterine prolactin could be a possible medical treatment option. In this pilot study, we aim to evaluate the effect of bromocriptine, a prolactin inhibitor, on menstrual bleeding and pain in women with adenomyosis.Material and methods23 women with diffuse adenomyosis were enrolled from a university hospital in Sweden and a tertiary care center in the USA. Nineteen patients completed 6 months of treatment with vaginal bromocriptine at a dose of 5 mg daily. Participants completed validated measures at baseline, 3 and 6 months of treatment, and at 9 months (3 months after cessation of bromocriptine). Validated measures utilized included Pictorial Blood Loss Assessment Chart (PBLAC), Aberdeen Menorrhagia Clinical Outcomes Questionnaire (AMCOQ), Visual Analog Scale for pain (VAS), McGill Pain Questionnaire (MPQ), Endometriosis Health Profile (EHP‐30), Female Sexual Function Index (FSFI) and the Fibroid Symptom Quality of Life (UFS‐QOL) symptom severity and health‐related quality of life (HRQL) subscores. Scores were compared between baseline and 9 months using the Wilcoxon signed rank test.ResultsMean age of participants was 44.8 years. About 77.8% reported PBLAC scores >250 and 68.4% reported moderate to severe pain at baseline. Compared with baseline, women had lower 9‐month scores (median [interquartile range] for all) on PBLAC (baseline 349 [292‐645] vs 9‐month 233 [149‐515], P = 0.003), VAS (5.0 [4‐8.3] vs 2.5 [0‐4.5], P < 0.001), EHP Core Pain (15.9 [9.1‐50.0] vs 3.4 [2.3‐34.1], P = 0.029), EHP Core Self‐image (41.7 [16.7‐58.3] vs 25 [0‐5], P = 0.048) and Symptom Severity Score (60 [44‐72] vs 44 [25‐56], P < 0.001) and higher HRQL scores (57 [37‐63] vs 72 [51‐85], P < 0.001) following bromocriptine treatment. Other EHP core parameters and FSFI were not significantly different.ConclusionsSignificant improvement in menstrual bleeding, pain and quality of life after vaginal bromocriptine treatment suggests a novel therapeutic agent for adenomyosis.

AbstractPurpose:CD38 has emerged as a high-impact therapeutic target in multiple myeloma, with the approval of daratumumab (anti-CD38 mAb). The clinical importance of CD38 in patients with chronic lymphocytic leukemia (CLL) has been known for over 2 decades, although it's relevance as a therapeutic target in CLL remains understudied.Experimental Design:We investigated the biological effects and antitumor mechanisms engaged by daratumumab in primary CLL cells. Besides its known immune-effector mechanisms (antibody-dependent cell-mediated cytotoxicity, complement-dependent death, and antibody-dependent cellular phagocytosis), we also measured direct apoptotic effects of daratumumab alone or in combination with ibrutinib. In vivo antileukemic activity was assessed in a partially humanized xenograft model. The influence of CD38 on B-cell receptor (BCR) signaling was measured via immunoblotting of Lyn, Syk, BTK, PLCγ2, ERK1/2, and AKT.Results:In addition to immune-effector mechanisms; daratumumab also induced direct apoptosis of primary CLL cells, which was partially dependent on FcγR cross-linking. For the first time, we demonstrated the influence of CD38 on BCR signaling where interference of CD38 downregulated Syk, BTK, PLCγ2, ERK1/2, and AKT; effects that were further enhanced by addition of ibrutinib. In comparison to single-agent treatment, the combination of ibrutinib and daratumumab resulted in significantly enhanced anti-CLL activity in vitro and significantly decreased tumor growth and prolonged survival in the in vivo CLL xenograft model.Conclusions:Overall, our data demonstrate the antitumor mechanisms of daratumumab in CLL; furthermore, we show how cotargeting BTK and CD38 lead to a robust anti-CLL effect, which has clinical implications.

Background Many adults eligible for statin therapy for cardiovascular disease prevention are untreated. Our objective was to investigate patient‐reported reasons for statin underutilization, including noninitiation, refusal, and discontinuation. Methods and Results This study included the 5693 adults recommended for statin therapy in the PALM (Patient and Provider Assessment of Lipid Management) registry. Patient surveys evaluated statin experience, reasons for declining or discontinuing statins, and beliefs about statins and cardiovascular disease risk. Overall, 1511 of 5693 adults (26.5%) were not on treatment. Of those not on a statin, 894 (59.2%) reported never being offered a statin, 153 (10.1%) declined a statin, and 464 (30.7%) had discontinued therapy. Women (relative risk: 1.22), black adults (relative risk: 1.48), and those without insurance (relative risk: 1.38) were most likely to report never being offered a statin. Fear of side effects and perceived side effects were the most common reasons cited for declining or discontinuing a statin. Compared with statin users, those who declined or discontinued statins were less likely to believe statins are safe (70.4% of current users vs. 36.9% of those who declined and 37.4% of those who discontinued) or effective (86.3%, 67.4%, and 69.1%, respectively). Willingness to take a statin was high; 67.7% of those never offered and 59.7% of patients who discontinued a statin would consider initiating or retrying a statin. Conclusions More than half of patients eligible for statin therapy but not on treatment reported never being offered one by their doctor. Concern about side effects was the leading reason for statin refusal or discontinuation. Many patients were willing to reconsider statin therapy if offered.

Background: Poly (ADP-ribose) polymerases (PARPs) are a highly conserved family of enzymes whose main function is to preserve genomic integrity following DNA damage. PARP inhibitors (PARPi) are increasingly used in cancers with deficiencies in homologous recombination. Clinical trials in breast and ovarian cancers have led to several FDA approvals in recent years, and their use in clinical practice is continuing to rise. It is thus necessary to assess their adverse event (AE) profile. Method: Literature search was performed using Ovid MEDLINE, EMBASE, CENTRAL, and Scopus (inception through October 26, 2018). Eligible studies were phase 3, randomized, controlled trials that compared single agent PARPi to placebo or standard treatment. Number of patients treated and AEs reported were recorded. Observed incidence of AE was reported with 95% CI. Heterogeneity was evaluated using Cochran Q statistic and I2 statistics quantified the proportion of heterogeneity not due to chance. Results: Databases revealed 869 references. Of these, 6 were eligible: 2 in breast cancer (OlympiAD, EMBRACA) and 4 in ovarian cancer (NOVA, ARIEL3, SOLO1, SOLO2). PARPi included niraparib (NOVA), olaparib (OlympiAD, SOLO1, SOLO2), rucaparib (ARIEL3), and talazoparib (EMBRACA). Of 1,685 patients who received PARPi, incidence of any AE, regardless of grade, was 98.5% (95% CI, 97.2–99.2%). Common AEs were: nausea (incidence rate, 68.9% and 95% CI, 58.7%–77.5%), fatigue (56.3%, 45.3%–66.8%), anemia (46.3%, 37.2%–55.8%), vomiting (33.7%, 29.5%–38.3%), neutropenia (24.7%, 15.3%–37.4%), headache (23.9%, 19.9%–28.4%), and reduced appetite (21.7%, 19.3%–24.3%). Myeloid neoplasms were rare (1.2%, 0.7%–1.9%). Incidence of grade 3 or higher AE was 44.3% (30.2%–59.5%) and often related to myelosuppression, specifically anemia (24.7%, 15.3%–37.4%), neutropenia (10.7%, 6.6%–16.9%), and thrombocytopenia (5.0%, 1.7%–14.0%). Incidence of serious AE was 24.3% (19.4%–29.9%); dose interruption occurred in 53.3% (41.2%–65.0%) and dose reduction occurred in 39.2% (23.6%–57.4%). 10% (7.4%–13.6%) of patients discontinued therapy due to AE. Death due to AE was rare; less than 1% (0.4%, 0.2%–0.8%) in all trials. Conclusion: Myelosuppression and gastrointestinal toxicities were the most commonly reported AE in 6 randomized phase 3 trials of PARPi for breast and ovarian cancers. Therapy was rarely discontinued due to AE. It remains to be seen whether these results will be reflected in clinical practice.
