ABSTRACT

BACKGROUND: Hormone therapy with aromatase inhibitors (AIs) for estrogen receptor-dependent breast cancer may expose patients to an increased osteoporosis risk. This study was performed to estimate fracture risk in women with breast cancer to whom AIs were prescribed in Japan. METHODS: This retrospective study used data from the Japanese Medical Data Vision database. Women with breast cancer prescribed AIs over a 12-month period were identified and matched to women not prescribed AIs using a propensity score. Fracture rates were estimated by a cumulative incidence function and compared using a cause-specific Cox hazard model. The proportion of women undergoing bone density tests was retrieved. RESULTS: For all fractures sites combined, cumulative fracture incidence at 10 years was 0.19 [95%CI: 0.16-0.22] in women prescribed AIs and 0.18 [95%CI: 0.15-0.21] without AIs. AI prescription was not associated with any changes in risk (adjusted hazard ratio: 1.08 [95%CI: 0.99-1.17] p = 0.08). Women prescribed AI more frequently underwent bone density testing (31.9% [95% CI: 31.2%; 32.6%] versus 2.2% [95% CI: 2.0%; 2.4%]). CONCLUSIONS: The anticipated association between AI exposure and osteoporotic fracture risk in Japanese women with breast cancer was not seen clearly.

ABSTRACT

AIMS: Although pruritus is a hallmark feature of atopic dermatitis, no study has investigated the associated impact of pruritus, due to atopic dermatitis in Japan. The study aimed to evaluate the real-life burden of atopic dermatitis by pruritus severity in adult Japanese patients. The primary objective was to assess the correlation between pruritus severity and work productivity and activity impairment. A secondary objective was to characterize the impact of pruritus on quality of life and to evaluate the burden of symptoms severity and frequency. MATERIALS AND METHODS: A cross-sectional internet-based survey was conducted. Eligible patients were currently employed and working adults with atopic dermatitis for at least 6 months. Stratification on pruritus severity assessed by the Worst Pruritus Numerical Rating Scale at the screening was performed to ensure that different severity groups are represented. Correlations were assessed using Spearman's rank-order correlation coefficient. Multivariate regression analyses were performed to assess the impact of pruritus severity on work productivity and quality of life. RESULTS: The study analyzed 370 patients. Pruritus severity significantly correlated with work impairment (Rho = 0.622, P value (H0: Rho > 0.5) <.001). A greater pruritus severity was associated with greater work productivity and activity impairment and a greater impact on quality of life, sleep, emotional state, and everyday activities. Patients with a greater pruritus severity carried a higher economic burden of treatment and were more often not satisfied with the received therapy. LIMITATIONS: All data were self-reported by patients via an online survey, which is associated with the risk of misclassification for diagnosis, recall bias, and limited participation of patients. CONCLUSIONS: The study provides evidence that pruritus is associated with the overall disease burden and impacts many important life aspects of patients with atopic dermatitis in Japan.

ABSTRACT

OBJECTIVE: Trauma, with resultant bleeding, is a significant cause of morbidity and mortality throughout the world; however, the best possible method of bleeding control by immediate responders is unknown. We performed a systematic review of the effectiveness of treatment modalities for severe, life-threatening external bleeding in the out-of-hospital first aid setting. Methods: We followed the Cochrane Handbook for Systematic Reviews of Interventions methodology and report results according to PRISMA guidelines. We included randomized controlled trials, non-randomized comparative studies and case series investigating adults and children with severe, life-threatening external bleeding who were treated with therapies potentially suitable for first aid providers. We assessed the certainty of the evidence and risk of bias. Outcomes were prioritized by first aid specialists based on importance for patients and decision-makers and included mortality due to bleeding, all-cause mortality, cessation of bleeding, time to cessation of bleeding, a decrease in bleeding, and complications/adverse effects. Results were reported in Evidence Profiles. Results: Of the 1,051 full-text articles screened, 107 were included for analysis including 22,798 patients. The primary methods of bleeding control were tourniquets (n = 49), hemostatic dressings (n = 34), hemostatic devices (n = 14), pressure dressings/bandages/devices (n = 8), pressure points (n = 4), including 2 studies that reported multiple hemorrhage control methods. Overall, certainty of evidence was very low and often relied on indirect evidence and poorly controlled studies. Tourniquets were associated with a decrease in mortality when compared with direct manual pressure. Hemostatic dressings resulted in a shorter time to hemostasis than direct manual pressure using standard dressings. Direct manual compression resulted in a shorter time to hemostasis than pressure dressings/devices. Conclusion: Overall, data regarding the control of life-threatening bleeding is of very low certainty, making it difficult to draw robust conclusions for treatment by immediate responders. While more robust data is needed on first aid treatments of life-threatening bleeding, this systematic review aggregates the most comprehensive to date to help guide recommendations. Key words: bleeding; hemorrhage; tourniquet; hemostatic dressing; direct pressure.

ABSTRACT

Patients receiving vitamin K antagonists (VKAs) with an international normalized ratio (INR) between 4.5 and 10 are at increased risk of bleeding. We systematically reviewed the literature to evaluate the effectiveness and safety of administering vitamin K in patients receiving VKA therapy with INR between 4.5 and 10 and without bleeding. Medline, Embase, and Cochrane databases were searched for relevant randomized controlled trials in April 2018. Search strategy included terms vitamin K administration and VKA-related terms. Reference lists of relevant studies were reviewed, and experts in the field were contacted for relevant papers. Two investigators independently screened and collected data. Risk ratios (RRs) were calculated, and certainty of the evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation. Six studies (1074 participants) were included in the review and meta-analyses. Pooled estimates indicate a nonsignificant increased risk of mortality (RR = 1.42; 95% confidence interval [CI], 0.62-2.47), bleeding (RR = 2.24; 95% CI, 0.81-7.27), and thromboembolism (RR = 1.29; 95% CI, 0.35-4.78) for vitamin K administration, with moderate certainty of the evidence resulting from serious imprecision as CIs included potential for benefit and harm. Patients receiving vitamin K had a nonsignificant increase in the likelihood of reaching goal INR (1.95; 95% CI, 0.88-4.33), with very low certainty of the evidence resulting from serious risk of bias, inconsistency, and imprecision. Our findings indicate that patients on VKA therapy who have an INR between 4.5 and 10.0 without bleeding are not likely to benefit from vitamin K administration in addition to temporary VKA cessation.
