Cancer care advances have led to increased numbers of cancer survivors and to improved understanding of late effects of cancers and their therapies and survivorship issues. Long-term follow-up of cancer patients is crucial in preventing and managing many of the late effects of cancers and their therapies. However, the literature has highlighted the high rates of loss to follow-up (loss to FU) after cancer treatment, particularly in patients with hematologic malignancies. In this review, we performed a systematic search of published literature on issues pertaining to loss to FU in survivors of hematologic malignancies, highlighting the predictors of increased or decreased rates of loss to FU. We found that the literature on survivors of adulthood cancers is very limited, in contrast to articles discussing young adult survivors of childhood cancers. Predictors and barriers of loss to FU were found to be variable in different studies; however, they shared some common themes, including disease-related, logistic, financial and educational factors. Furthermore, we discuss the potential interventions to mitigate the loss to FU, along with discussing research priorities in this area. INTRODUCTION Data on the prevalence of depression and anxiety in elderly cardiovascular disease patients are limited and there are only few studies focussing on treatment effects. Thus, the current study aimed to analyse elderly patients suffering from aortic stenosis (AS) and undergoing transcatheter aortic valve replacement (TAVR) with respect to both, prevalence rates before TAVR and dynamics in the clinical course. METHODS The study included 140 AS patients undergoing TAVR (77.8 ± 7.7 years, 42.9% male, mean STS-Score 4.4 ± 2.2). Detailed clinical, laboratory and functional analysis was performed. In addition, quality of life (EQ-5D, EQ VAS), clinical frailty (CFS) and anxiety/depression (HADS-D), was assessed at baseline, 6 weeks, 6 months and 12 months after TAVR. RESULTS Before TAVR, HADS-D revealed ≥8 points for anxiety and/or depression in 54 patients (38.6%), depression in 33 patients (23.6%) and for anxiety in 40 patients (28.6%). In the group showing HADS-D ≥8 points for anxiety, there was an improvement already 6 weeks after TAVR for anxiety (p  less then  0.05) but not for depression. Y27632 In the group showing HADS-D ≥8 points for depression, there was a significant improvement at the 6 weeks' follow-up for both, depression (p  less then  0.001) and anxiety (p = 0.012) remaining stable for depression but not for anxiety until 12 months after TAVR. CONCLUSIONS TAVR leads to reductions of depression and anxiety in patients showing pathologic baseline values in HADS-D. There were no associations between pre-existing depression and anxiety with long-term mortality in our study. BACKGROUND Alterations in intracellular Na+ and Ca2+ have been observed in patients with Duchenne muscular dystrophy (DMD) and in animal models of DMD, and inhibition of Na+-H+ exchanger 1 (NHE1) by rimeporide has previously demonstrated cardioprotective effects in animal models of myocardial ischemia and heart failure. Since heart failure is becoming a predominant cause of death in DMD patients, this study aimed to demonstrate a cardioprotective effect of chronic administration of rimeporide in a canine model of DMD. METHODS Golden retriever muscular dystrophy (GRMD) dogs were randomized to orally receive rimeporide (10 mg/kg, twice a day) or placebo from 2 months to 1 year of age. Left ventricular (LV) function was assessed by conventional and advanced echocardiography. RESULTS Compared with placebo-treated GRMD, LV function deterioration with age was limited in rimeporide-treated GRMD dogs as indicated by the preservation of LV ejection fraction as well as overall cardiac parameters different from placebo-treated dogs, as revealed by composite cardiac scores and principal component analysis. In addition, principal component analysis clustered rimeporide-treated GRMD dogs close to healthy control dogs. CONCLUSIONS Chronic administration of the NHE1 inhibitor rimeporide exerted a protective effect against LV function decline in GRMD dogs. This study provides proof of concept to explore the cardiac effects of rimeporide in DMD patients. BACKGROUND Diabetic (DM) inactivation of small conductance calcium-activated potassium (SK) channels contributes to coronary endothelial dysfunction. However, the mechanisms responsible for this down-regulation of endothelial SK channels are poorly understood. Thus, we hypothesized that the altered metabolic signaling in diabetes regulates endothelial SK channels and human coronary microvascular function. METHODS Human atrial tissue, coronary arterioles and coronary artery endothelial cells (HCAECs) obtained from DM and non-diabetic (ND) patients (n = 12/group) undergoing cardiac surgery were used to analyze metabolic alterations, endothelial SK channel function, coronary microvascular reactivity and SK gene/protein expression/localization. RESULTS The relaxation response of DM coronary arterioles to the selective SK channel activator SKA-31 and calcium ionophore A23187 was significantly decreased compared to that of ND arterioles (p less then 0.05). Diabetes increases the level of NADH and the NADH/NAD+ ratio in human myocardium and HCAECs (p less then 0.05). Increase in intracellular NADH (100 μM) in the HCAECs caused a significant decrease in endothelial SK channel currents (p less then 0.05), whereas, intracellular application of NAD+ (500 μM) increased the endothelial SK channel currents (p less then 0.05). Mitochondrial reactive oxygen species (mROS) of HCAECs and NADPH oxidase (NOX) and PKC protein expression in the human myocardium and coronary microvasculature were increased respectively (p less then 0.05). CONCLUSIONS Diabetes is associated with metabolic changes in the human myocardium, coronary microvasculature and HCAECs. Endothelial SK channel function is regulated by the metabolite pyridine nucleotides, NADH and NAD+, suggesting that metabolic regulation of endothelial SK channels may contribute to coronary endothelial dysfunction in the DM patients with diabetes. AIMS AND OBJECTIVES To explore the meaning of maternal caregiving in the Chinese culture for children newly diagnosed with acute lymphocytic leukemia (ALL). BACKGROUND Recurrence of and death associated with ALL remain the main concerns for mothers. Mothers experience guilt and anxiety towards their child's cancer. DESIGN Descriptive phenomenological study. METHODS Twelve mothers were recruited from a medical centre in Central Taiwan. The mothers were primary caregivers for their child diagnosed as having ALL in the past 3 months to 1 year. Data were collected through semi-structured interviews and analysed using Colaizzi's method. RESULTS Four main themes emerged feeling this world crashing by knowing the diagnosis, feeling the double-edged sword of mothering, worrying about potential risks for their vulnerable child, and passing through difficulties with power of support. CONCLUSIONS Most mothers felt this world crashing due to potential loss of their child and seeing their child's suffering. The mother was blamed for her child's cancer but was also required to shoulder all caregiving for their child. The mothers needed to compromise their lives to protect their child from potential infection. Perceived power of support helped the mothers overcome difficulties. RELEVANCE TO CLINICAL PRACTICE Findings support that nurses encouraging mothers to tell their stories, regardless of culture, will facilitate healing. Establishing trust and providing support from nurses, physicians, psychologists and social workers will lead mothers' readiness to deal with care of their sick child. Increasing visiting time for parental support for children hospitalized in the PICU is suggested as well. BACKGROUND There is limited information on the relationship between modifiable lifestyle factors and Takotsubo syndrome (TS). OBJECTIVES To determine the association of physical activity, smoking, alcohol use, and caffeinated coffee consumption with TS. METHODS This case-control study enrolled women with newly diagnosed TS (n = 45), women post-myocardial infarction (MI; n = 32), and healthy women volunteers (HC; n = 30). Information on physical activity, smoking, alcohol use, and caffeinated coffee consumption was collected 1-month post-discharge for TS and MI, and 1-month post-enrollment for HC. RESULTS TS women reported a higher prevalence of lifetime smoking and cigarette packs/day, greater coffee consumption, and less physical activity than HC. Associations with cigarette and coffee use remained significant in adjusted models. Physical activity, smoking, and coffee consumption were similar in TS and MI women. CONCLUSIONS Use of psychostimulants (caffeine and cigarettes) may play a role in TS pathophysiology. These findings need to be confirmed in larger, fully powered studies. Left ventricular assist devices (LVAD) are increasingly being used to treat end-stage heart failure. Despite the increased prevalence of these devices, there is a still a high 1-year mortality rate. The purpose of this integrative review was to systematically evaluate research studies that focused on the process and content of LVAD related end-of-life discussions. A literature search was conducted from earliest available date to November, 2017. A total of 59 citations were produced, 13 articles went under full review, and six studies remained for inclusion in this review. Patients and their caregivers experienced confusion and frustration regarding the end-of-life experiences and care related to disjointed care by their provider teams. Clinician experiences and opinions also suggested a controversy about deactivation of the LVAD at the end-of-life, and a divide regarding practices at the end-of-life. Research focused on system-level factors involved in end-of-life care for patients with an LVAD is needed. BACKGROUND How respiratory muscle strength influences the effectiveness of pulmonary rehabilitation (PR) in patients with chronic obstructive pulmonary disease (COPD) is unclear. OBJECTIVE To investigate the benefits of PR in subjects with COPD according to respiratory muscle strength. METHODS Ninety-seven subjects with COPD were evaluated using maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), pulmonary function tests, the cardiopulmonary exercise test (CPET), and the St. George's Respiratory Questionnaire (SGRQ). Subjects were divided into four groups 1 (normal MIP and MEP); 2 (low MIP); 3 (low MEP); and 4 (low MIP and MEP). Subjects underwent PR for 3 months; MIP, MEP, SGRQ, and CPET were evaluated post-PR. RESULTS Subjects with both poor MIP and MEP had the highest dyspnea score, lowest exercise capacity, and poorest health-related quality of life (HRQoL). PR improved exercise capacity and HRQoL in all groups, with more improvement in MIP, MEP, tidal volume (on exercise), and dyspnea (at rest) in subjects with both low MIP and MEP. CONCLUSIONS Patients with respiratory muscle weakness had worse dyspnea, lower exercise capacity, and poorer HRQoL at baseline. Exercise training improved respiratory muscle strength with concurrent improvement of exercise capacity, HRQoL, and dyspnea score. Subjects with both poor baseline MIP and MEP showed greater benefits of PR.
