The fludarabine,cytarabine, and granulocyte colony‐stimulating factor (FLAG) chemotherapy regimen is an alternative to anthracycline‐based therapy for the treatment of acute myeloid leukemia for patients with pre‐existing cardiac disease

We conducted a retrospective study assessing FLAG (fludarabine, cytarabine, and granulocyte colony‐stimulating factor) as first‐line treatment in 56 newly diagnosed acute myeloid leukemia patients considered ineligible for anthracycline‐based treatment due to advanced age, significant comorbidities, or pre‐existing cardiac disease. The median age was 69 (21–80); 46% received FLAG for pre‐existing cardiac disease and others due to age (32%), non‐cardiac comorbidities (20%), or previous anthracycline exposure (2%). The induction mortality was 16% and, among evaluable patients, 48% achieved a complete remission after the first induction course with an additional patient achieving a remission after a second course for a total complete remission rate of 50%. Four patients proceeded to an allogeneic stem cell transplant including two with pre‐existing cardiac disease. Among non‐transplanted patients, the relapse rate (RR) was 47%. When censored at time of stem cell transplant, the median relapse‐free survival was 14.7 months. The median overall survival was 9.3 months with 1‐ and 2‐yr survivals of 44% and 22%, respectively. There was no difference in clinical outcomes between patients treated with FLAG for cardiac reasons vs. other reasons. In conclusion, FLAG is a useful alternative to anthracycline‐based induction for Acute myeloid leukemia in those with significant comorbidities including pre‐existing cardiac disease.     

Subjective cognitive complaints and amyloid burden in cognitively normal older individuals

Accumulating evidence suggests that subjective cognitive complaints (SCC) may indicate subtle cognitive decline characteristic of individuals with preclinical Alzheimer’s disease (AD). In this study, we sought to build upon previous studies by associating SCC and amyloid-β deposition using positron emission tomography with Pittsburgh Compound B (PiB-PET) in cognitively normal older individuals. One-hundred thirty one subjects (mean age 73.5±6) were administered three subjective cognitive questionnaires and a brief neuropsychological battery. A relationship between a subjective memory complaints composite score and cortical PiB binding was found to be significant, even after controlling for depressive symptoms. By contrast, there were no significant relationships between objective cognitive measures of memory and executive functions and cortical PiB binding. Our study suggests that SCC may be an early indicator of AD pathology detectable prior to significant objective impairment.     

Mrs. Doubtfire Mentoring Program: Helping Children in Residential Care Transition to Bedtime

An exploratory qualitative study was conducted for the Mrs. Doubtfire mentoring program designed to connect volunteers with young children (6–11 years) in residential care to help with the bedtime transition and develop positive relationships with caring adults. Details of the program are provided. Positive effects on the agency, staff, volunteers, and children are discussed. Mrs. Doubtfire provides an innovative approach to meeting needs of children in residential care while also building strong community relationships and dedicated volunteers.     

MRP8/14 does not contribute to dissemination or inflammation in a murine model of Lyme borreliosis

Myeloid-related protein (MRP)8 and MRP14 form a complex (MRP8/14) that is released by activated neutrophils and monocytes during infection. MRP8/14 has been shown to have bacteriostatic activity in vitro against Borrelia burgdorferi, the spirochete that causes Lyme borreliosis. Furthermore, levels of MRP8/14 have been shown to be elevated in the joints of patients with Lyme arthritis. We hypothesized that MRP8/14 has a protective effect during B. burgdorferi infection. To determine the role of MRP8/14 in the immune response to B. burgdorferi, we studied the course of B. burgdorferi infection in wildtype (wt) and mrp14^?/? mice. In addition, we studied the response of leukocytes from mice lacking MRP8/14 to B. burgdorferi ex vivo. We demonstrated similar levels of B. burgdorferi dissemination, cytokine and immunoglobulin production in infected wt and mrp14^?/? mice after 21 days. Neutrophils and monocytes lacking MRP8/14 were undiminished in their ability to become activated or phagocytose B. burgdorferi. In conclusion, we did not find a central role of MRP8/14 in the immune response against B. burgdorferi. As the levels of MRP8/14 in the serum of infected mice were low, we speculate that MRP8/14 is not released in levels great enough to influence the course of B. burgdorferi infection.     

Assessing Needs and Resources for the Home Visiting System in Alabama: A Mixed Methods Approach

The purpose of this article is to describe the initial assessment for the development of a home visiting (HV) system in a state with no existing system. We outline a mixed methods process where the quantitative component was used to identify the communities that possess “at-risk” profiles, and the qualitative component explored the resources and gaps in existing HV services. We employed a mixed methods approach, using six categories of indicators from quantitative secondary data sources to identify “at-risk” profiles for Alabama’s 67 counties. A weighted score for each indicator was calculated and counties were ranked. Surveys and focus groups were conducted to further define resources and gaps of existing HV programs. The composite indicator scores identified 13 counties as having the highest level of risk. Five of these 13 communities had no HV home visitation services. Areas of focus for future HV system development include trust, communication, availability, cost, and timeliness. In this assessment related to the Alabama HV system, we used quantitative data to apply criteria to the indicators being measured and qualitative data to supplement the quantitative findings. We examined resources, gaps, program quality, and capacity of the existing HV programs in order to assist in the future development of the HV system and early childhood system. The methods presented in this paper have potential applications beyond HV programs and systems, including broader examinations of complex systems for service provision to the maternal and child health populations.     

Effects of short-term supplementation with bovine lactoferrin and/or immunoglobulins on body mass and metabolic measures: a randomised controlled trial

Given the role of the intestinal microbiota in obesity and related disease, strategies to modulate the composition of the intestinal microbiota may augment traditional weight-management approaches. Here, we examined the safety and tolerability of 28 days of supplementation with bovine whey-derived lactoferrin and immunoglobulin supplements in a cross-sectional cohort of free-living adults. Participants (n?=?20 each group) received enteric-coated whey-derived bovine lactoferrin (200?mg), immunoglobulin (200?mg or 800?mg), combination lactoferrin/immunoglobuiln supplements (200?mg/200?mg, 200?mg/800?mg) or placebo in a double-blind design. Supplement use was generally well tolerated and routine haematology, and clinical chemistry measures were largely unchanged following supplementation. Measures of body composition remained stable and indices of glycaemic control and blood lipids revealed fluctuations of?<5% but were not significantly different between groups. Overall, short-term lactoferrin/immunoglobulin supplementation was well tolerated in this cohort; use of these types of supplements to enhance other weight management strategies should be investigated over extended periods.     

FRAX and mandibular sparse trabeculation as fracture predictors: a longitudinal study from 1980 to 2002

The fracture assessment tool (FRAX) is widely used for predicting fractures, but better methods are needed. The aim of this study was to determine whether visual assessments of mandibular trabecular bone could improve FRAX predictions. Three age‐cohorts of women were examined twice – 499 women in 1980/1981 and 412 women in 1992/1993; 397 participated in both examinations. Information on 10‐yr fracture events was available, and bone trabeculation was assessed in radiographs as ‘dense’, ‘mixed’, or ‘sparse’. Fracture assessment tool values, without bone mineral density (BMD), were calculated twice. Both sparse trabeculation and FRAX >15% were associated with a twofold higher risk for future fracture in the younger group and with a three‐ to fourfold higher risk for future fracture in the older group. For those with both FRAX >15% and sparse trabeculation, the relative risk (RR) for a fracture in the next 10 yr was 5.9 (95% CI: 3.5–9.8) in the younger group and 22.7 (95% CI: 5.6–92) in the older group. If either FRAX >15% or sparse trabeculation was present, the RR was 2.6 (95% CI: 1.7–4.1) in the younger group and 15.7 (95% CI: 3.9–6.4) in the older group. We concluded that FRAX >15%, without BMD measurements, was an effective fracture predictor, and mandibular sparse trabeculation had a substantial additive effect. Together, FRAX plus mandibular sparse trabeculation predicts major osteoporotic fractures to approximately the same extent as does FRAX with BMD measurements.     

The red connection: a review of aortic and arterial fistulae with an emphasis on CT findings

Fistulae between the aorta and adjacent structures are a rare, emergent, and potentially life-threatening process. Most commonly, aortic fistulae arise secondarily as a complication of prior aortic surgery with fistulization to adjacent structures. Rarely, a primary fistula may arise from the aorta in the setting of a pre-existing aneurysm or from a mass, inflammation, or infection. Although the incidence of aortic fistulae remains low, the frequency continues to increase as aortic surgical interventions and post-surgical follow-up with imaging become more common. Computed tomography (CT) is the modality of choice in evaluating the patient with suspected aortic fistula because of its accessibility and short scan time. In addition, CT allows for more clear depiction of para-aortic or intra-aortic gas than ultrasound or magnetic resonance (MR). This gas may be the first clue of a fistula. Given the high mortality associated with aortic fistulae, familiarity with the imaging findings of the spectrum of aortic fistulae is essential knowledge in the emergency setting. This review will discuss the imaging appearance of aortic and arterial fistulae to the bronchi, esophagus, gastrointestinal tract, ureters, and veins on CT.
