One of the most controversial health decisions facing women is deciding upon the use of hormonal treatments for symptoms of menopause. This brief review focuses on the historical context of use of menopausal hormone treatments (MHT), summarizes results of major observational, primary and secondary prevention studies of MHT and cardiovascular (CV) outcomes, provides evidence for how sex steroids modulate CV function and identifies challenges for future research. As medicine enters an era of personalization of treatment options, additional research into sex differences in the aetiology of CV diseases will lead to better risk identification for CV disease in women and identify whether a woman might receive CV benefit from specific formulations and doses of MHT.

Abstract Background: Ixabepilone, an epothilone B analog, has demonstrated single-agent activity in metastatic and neoadjuvant settings. The PACS08 trial aimed to compare adjuvant FEC100-Docetaxel regimen to FEC100-Ixabepilone in poor prognosis early breast cancer (BC) composed of patients presenting with triple-negative (TN) [i.e. estrogen receptor (ER)-/progesterone receptor (PR)-/HER2-] or ER+/PR-/HER2- tumor, which are subgroups significantly associated with worse prognosis. Patients and methods: Between 2007 and 2010, 762 patients with unilateral TNBC (n=592, 78%) or node-positive ER+/PR-/HER2- BC (n=170, 22%) were enrolled. Recruitment was interrupted due to BMS decision to stop ixabepilone development in adjuvant setting. Main inclusion criteria were: age<70 years, normal cardiac, hepatic, haematological and renal functions. Arm A: pts received 3 cycles of FEC100 (F and C, each at 500 mg/m2, E 100 mg/m2, every 3 weeks) followed by 3 cycles of Docetaxel (100 mg/m2 every 3 weeks); Arm B, Ixabepilone 40 mg/m2 replaced Docetaxel. Radiotherapy was mandatory after conservative surgery and endocrine therapy was given to ER+ pts. ER, PR and HER2 status were validated by a central pathology review on 754 cases and Immunohistochemical detection of Ki67, EGFR, cytokeratins (CK) 5/6 and 14, was performed on tissue microarray (TMA). Results: Main pts characteristics were well balanced between the 2 arms. As of September 2014, the median follow-up was 36 months. The safety profile indicates that Docetaxel is more often associated to significant haematological toxicities whereas both neurotoxicities and haematological toxicities are reported in Ixabepilone arm. Log-Rank tests indicate no difference between two arms in terms of both DFS and OS (HR=1.2, 95%CI (0.864-1.728), p=0.256 and HR=1.8, 95%CI (0.751-1.855), p=0.473, respectively). Pathological analysis of the PACS08 collection showed that TNBC displayed significantly higher proliferative activity as shown by mitotic count and Ki67 index (p<0.001). As compared to ER+/PR-/HER2- subgroup, TNBC showed distinct characteristics, and displayed a so-called basal-like phenotype in 80%. Further efficacy analyses are ongoing in order to study whether chemotherapy may have better prognosis according to pathological characteristics including tumor lymphocytic infiltrate. These additional data will be available for the SABCS2015 meeting. Conclusions: Our results indicate that Ixabepilone doesn't show higher efficiency compared to Docetaxel in adjuvant setting in poor prognosis early breast cancer. We have an unusual biological collection associated to our clinical data which will allow us to correlate efficacy data to breast cancer subgroups. Other several translational researches are still ongoing.

Germline mutations in the DNA base excision repair gene MUTYH are known to increase a carrier's risk of colorectal cancer. However, the risks of other (extracolonic) cancers for MUTYH mutation carriers are not well defined. We identified 266 probands (91% Caucasians) with a MUTYH mutation (41 biallelic and 225 monoallelic) from the Colon Cancer Family Registry. Mutation status, sex, age and histories of cancer from their 1,903 first‐ and 3,255 second‐degree relatives were analyzed using modified segregation analysis conditioned on the ascertainment criteria. Compared with incidences for the general population, hazard ratios (HRs) (95% confidence intervals [CIs]) for biallelic MUTYH mutation carriers were: urinary bladder cancer 19 (3.7–97) and ovarian cancer 17 (2.4–115). The HRs (95% CI) for monoallelic MUTYH mutation carriers were: gastric cancer 9.3 (6.7–13); hepatobiliary cancer 4.5 (2.7–7.5); endometrial cancer 2.1 (1.1–3.9) and breast cancer 1.4 (1.0–2.0). There was no evidence for an increased risk of cancers at the other sites examined (brain, pancreas, kidney or prostate). Based on the USA population incidences, the estimated cumulative risks (95% CI) to age 70 years for biallelic mutation carriers were: bladder cancer 25% (5–77%) for males and 8% (2–33%) for females and ovarian cancer 14% (2–65%). The cumulative risks (95% CI) for monoallelic mutation carriers were: gastric cancer 5% (4–7%) for males and 2.3% (1.7–3.3%) for females; hepatobiliary cancer 3% (2–5%) for males and 1.4% (0.8–2.3%) for females; endometrial cancer 3% (2%–6%) and breast cancer 11% (8–16%). These unbiased estimates of both relative and absolute risks of extracolonic cancers for people, mostly Caucasians, with MUTYH mutations will be important for their clinical management.

Background: Advance care planning (ACP) is an instrumental mechanism aimed at preserving patient autonomy. Numerous interventions have been proposed to facilitate the implementation of ACP; however, rates of completed advance directives (ADs) are universally low. Patient electronic portal messaging is a newer tool in patient–provider communication which has not been studied as a method to promote ACP. In this study, we hypothesized that the use of ACP-specific patient electronic messages would increase rates of AD completion in patients aged 65 years and older in an academic primary care practice. Methods: All primary care patients, aged 65+, who had previously enrolled in a patient electronic messaging system, within an academic primary care practice, were included for randomization. Two hundred patients were randomized to receive an electronic message. The primary outcome was the proportion of patients in each group who completed an AD, 3 months after intervention. Secondary outcomes included clinical utility of the completed ADs and proportion of patients who viewed their electronic messages. Results: The intervention group completed an AD 5.5% of the time when compared to 2% in the control group (odds ratio 3.2 [1.6-6.3]). Up to 74.5% of patients opened their electronic messages. Conclusion: Among primary care patients aged 65 years and older, use of AD-specific electronic messaging statistically significantly increased the rate of AD completion, but the absolute number of completed AD remained relatively low. These data suggest that this valuable communication tool holds opportunities for further improvement. Older, frailer adults were more likely to complete an AD, and prompted directives were more likely to include a written expression of the individual’s health-care values and preference.

Objective: To establish evidence-based guidelines for the use of bedside cardiac ultrasound, echocardiography, in the ICU and equivalent care sites. Methods: Grading of Recommendations, Assessment, Development and Evaluation system was used to rank the “levels” of quality of evidence into high (A), moderate (B), or low (C) and to determine the “strength” of recommendations as either strong (strength class 1) or conditional/weak (strength class 2), thus generating six “grades” of recommendations (1A–1B–1C–2A–2B–2C). Grading of Recommendations, Assessment, Development and Evaluation was used for all questions with clinically relevant outcomes. RAND Appropriateness Method, incorporating the modified Delphi technique, was used in formulating recommendations related to terminology or definitions or in those based purely on expert consensus. The process was conducted by teleconference and electronic-based discussion, following clear rules for establishing consensus and agreement/disagreement. Individual panel members provided full disclosure and were judged to be free of any commercial bias. Results: Forty-five statements were considered. Among these statements, six did not achieve agreement based on RAND appropriateness method rules (majority of at least 70%). Fifteen statements were approved as conditional recommendations (strength class 2). The rest (24 statements) were approved as strong recommendations (strength class 1). Each recommendation was also linked to its level of quality of evidence and the required level of echo expertise of the intensivist. Key recommendations, listed by category, included the use of cardiac ultrasonography to assess preload responsiveness in mechanically ventilated (1B) patients, left ventricular (LV) systolic (1C) and diastolic (2C) function, acute cor pulmonale (ACP) (1C), pulmonary hypertension (1B), symptomatic pulmonary embolism (PE) (1C), right ventricular (RV) infarct (1C), the efficacy of fluid resuscitation (1C) and inotropic therapy (2C), presence of RV dysfunction (2C) in septic shock, the reason for cardiac arrest to assist in cardiopulmonary resuscitation (1B–2C depending on rhythm), status in acute coronary syndromes (ACS) (1C), the presence of pericardial effusion (1C), cardiac tamponade (1B), valvular dysfunction (1C), endocarditis in native (2C) or mechanical valves (1B), great vessel disease and injury (2C), penetrating chest trauma (1C) and for use of contrast (1B–2C depending on indication). Finally, several recommendations were made regarding the use of bedside cardiac ultrasound in pediatric patients ranging from 1B for preload responsiveness to no recommendation for RV dysfunction. Conclusions: There was strong agreement among a large cohort of international experts regarding several class 1 recommendations for the use of bedside cardiac ultrasound, echocardiography, in the ICU. Evidence-based recommendations regarding the appropriate use of this technology are a step toward improving patient outcomes in relevant patients and guiding appropriate integration of ultrasound into critical care practice.

Abstract Invariant NKT (iNKT) cells are a unique lineage with characteristics of both adaptive and innate lymphocytes, and they recognize glycolipids presented by an MHC class I–like CD1d molecule. During thymic development, iNKT cells also differentiate into NKT1, NKT2, and NKT17 functional subsets that preferentially produce cytokines IFN-γ, IL-4, and IL-17, respectively, upon activation. Newly selected iNKT cells undergo a burst of proliferation, which is defective in mice with a specific deletion of NKAP in the iNKT cell lineage, leading to severe reductions in thymic and peripheral iNKT cell numbers. The decreased cell number is not due to defective homeostasis or increased apoptosis, and it is not rescued by Bcl-xL overexpression. NKAP is also required for differentiation into NKT17 cells, but NKT1 and NKT2 cell development and function are unaffected. This failure in NKT17 development is rescued by transgenic expression of promyelocytic leukemia zinc finger; however, the promyelocytic leukemia zinc finger transgene does not restore iNKT cell numbers or the block in positive selection into the iNKT cell lineage in CD4-cre NKAP conditional knockout mice. Therefore, NKAP regulates multiple steps in iNKT cell development and differentiation.
