Bipartite Unique Neighbour Expanders via Ramanujan Graphs.

We construct an infinite family of bounded-degree bipartite unique neighbour expander graphs with arbitrarily unbalanced sides. Although weaker than the lossless expanders constructed by Capalbo et al., our construction is simpler and may be closer to being implementable in practice, due to the smaller constants.

Perceptions of Israeli women with breast cancer regarding the role of the Breast Care Nurse throughout all stages of treatment: a multi center study.

Purpose Of The Research: The role of the Breast Care Nurse (BCN) is well established in Israel. The purpose of this study is to examine the impact of the BCN on Israeli women with breast cancer at all stages of disease from diagnosis, through treatment and follow-up.

Methods: This was a descriptive multi-center study on 321 women with non-metastatic breast cancer who completed their treatment <5 years before.

Posttraumatic stress, nonadherence, and adverse outcome in survivors of a myocardial infarction.

Objective: Posttraumatic stress disorder (PTSD) symptoms have been reported in patients with coronary vascular disease, after the trauma of a myocardial infarction (MI). The effect of these symptoms on post-MI disease control has not been elucidated. We conducted a study that sought to determine whether PTSD symptoms post-MI are associated with increased likelihood of cardiovascular readmission and with nonadherence to treatment recommendations.

Lack of aspirin effect: aspirin resistance or resistance to taking aspirin?

Background: A lack of aspirin effect on platelets after a myocardial infarction (MI) is associated with poor health outcome. This lack of effect may be due to biological resistance to aspirin or due to nonadherence (the patient is not taking the aspirin, hence it has no effect). Determining which of these factors predicts poor outcome would inform potential intervention strategies.
