Amlexanox Exhibits Cardioprotective Effects in 5/6 Nephrectomized Rats

Abstract Cardiorenal syndrome is a life-threatening condition. The aim of the current study was to determine the cardioprotective effects of amlexanox in 5/6 nephrectomized rats. Rats were randomly assigned to three groups: sham, 5/6 nephrectomized rats, and amlexanox-treated 5/6 nephrectomized group. Amlexanox (25 mg/kg/day, i.p.) administration was started just after surgery and continued for 10 weeks. After treatment, kidney function (serum creatinine and urea) and blood pressure (systolic and diastolic) were measured. Heart weight (normalized to tibial length) and fibrosis area percentage were measured. Serum brain natriuretic peptide (BNP, heart failure marker) and cardiac levels of ß1-adrenergic receptor (ß1AR), ß-arrestin-2, phosphatidylinositol-4,5-bisphosphate (PIP2), diacylglycerol (DAG), pS473 Akt (a survival marker), and caspase-3 activity (an apoptosis marker) were also measured. The 5/6 nephrectomy caused renal impairment, cardiac fibrosis, apoptosis, and heart failure indicated by down- regulation of cardiac ß1AR down-stream signals compared with those in the sham group. Interestingly, amlexanox significantly reduced all cardiopathological changes induced after 10 weeks of 5/6 nephrectomy. Amlexanox showed potent cardiac antifibrotic and antiapoptotic effects in 5/6 nephrectomized rats, which were associated with reduced heart failure. To our knowledge, this is the first study that addresses the potent in vivo cardioprotective effects of amlexanox

Impact of the model of long-term follow-up care on adherence to guideline-recommended surveillance among survivors of adolescent and young adult cancers.

PURPOSE: Adolescent and young adult cancer survivors require lifelong healthcare to address the late effects of therapy. We examined the impact of different provider models of long-term follow-up (LTFU) care on adherence to recommended surveillance. METHODS: We conducted a retrospective cohort study using administrative health databases in Ontario, Canada. Five-year survivors were identified from IMPACT, a database of patients aged 15-20.9 years at diagnosis of six cancers between 1992 and 2010. We defined three models of LTFU care hierarchically: specialized survivor clinics (SCCs), general cancer clinics (GCCs), and family physician (FP). We assessed adherence to the Children's Oncology Group surveillance guidelines for cardiomyopathy and breast cancer. Multistate models assessed adherence transitions and impacts of LTFU attendance. RESULTS: A total of 1574 survivors were followed for a mean of 9.2 years (range 4.3-13.9 years) from index (5-year survival). The highest level of LTFU attended in the first 2-years post-index was a GCC (47%); only 16.7% attended a SCC. By the end of study, 72% no longer attended any of the models of care and only 2% still attended an SCC. Among 188 survivors requiring breast cancer surveillance, 6.9% were adherent to their first required surveillance testing. Attendance at a SCC in the previous year and higher cumulative FP or GCC visits increased the rate of subsequently becoming adherent. Among 857 survivors requiring cardiomyopathy surveillance, 11% were adherent at study entry. Each subsequent SCC visit led to an 11.3% (95% CI: 1.05-1.18) increase in the rate of becoming adherent. CONCLUSION: LTFU attendance and surveillance adherence are sub-optimal. SCC follow-up is associated with greater adherence, but few survivors receive such care, and this proportion diminished over time. Interventions are needed to improve LTFU attendance and promote surveillance adherence.

Standardizing the categorizations of models of aftercare for survivors of childhood cancer.

BACKGROUND: With significant improvements in the survival rates for most childhood cancers, there is increased pressure to determine how follow-up or aftercare for survivors is best structured. MAIN BODY: Previous work in this area has not been consistent in how it categorizes models of aftercare, which risks confusion between studies and evaluations of different models. The adoption of a standardized method for classifying and describing different models of aftercare is necessary in order to maximize the applicability of the available evidence. We identify some of the different ways models of aftercare have been classified in previous research. We then propose a revised taxonomy which allows for a more consistent classification and description of these models. The proposed model bases the classification of models of aftercare on who is the lead provider, and then collects data on five other key features: which other providers are involved in providing aftercare, where care is provided, how are survivors engaged, which services are provided, and who receives aftercare. CONCLUSION: There is a good deal of interest in the effectiveness of different models of aftercare. Future research in this area would be assisted by the adoption of a shared taxonomy that will allow programs to be identified by their structural type.

[Assessment of functioning in patients with head and neck cancer based on the international classification of functioning, disability and health (ICF)]. / Beurteilung von Funktionsfähigkeit bei Patienten mit Kopf-Hals-Tumoren, auf Basis der Internationalen Klassifikation für Funktionsfähigkeit, Behinderung und Gesundheit (ICF).

The article approaches with the question how preservation of function after treatment of head and neck cancer (HNC) can be defined and measured across treatment approaches. On the basis of the "International Classification of Functioning, Disability and Health (ICF)" a series of efforts are summarized how all relevant aspects of the interdisciplinary team can be integrated into a common concept.Different efforts on the development, validation and implementation of ICF Core Sets for head and neck cancer (ICF-HNC) are discussed. The ICF-HNC covers organ-based problems with food ingestion, breathing, and speech, as well as psychosocial difficulties.Relationships between the ICF-HNC and well-established outcome measures are illustrated. This enables the user to integrate different aspects of functional outcome into a consolidated approach towards preservation/rehabilitation of functioning after HNC - applicable for a variety of treatment-approaches and health-professions.

Women's Initiative for Nonsmoking-VII: evaluation of health service utilization and costs among women smokers with cardiovascular disease.

PURPOSE: The Women's Initiative for Nonsmoking (WINS), a randomized clinical trial of a smoking cessation intervention for women with cardiovascular disease, permitted an assessment of the types and costs of health services women used during the 30 months after their hospitalization with cardiovascular disease. METHODS: A prospective design nested within WINS was used for this study. A structured telephone interview guide included questions about medical services and 15 categories of prevention services, including cardiac rehabilitation at 6, 12, 24, and 30 months. Costs were estimated from state and national databases. RESULTS: The 277 women studied had a mean age of 60.7 +/- 10 years. They had smoked approximately 40 +/- 11.4 years. More than 50% of the women had one or more risk factors for cardiovascular disease. During the first 6 months after the index hospitalization, 94% had a physician visit, 39% had an emergency-room visit, and 36% had a hospital admission. Prevention services used were home healthcare by nurse or home health aide (26%), a cardiac rehabilitation program, including Multifit and Heart Smart (19%), and physical therapy (14%). Usage decreased over the 30 months. For the women who used any service, the mean total monthly cost per woman was 913 dollars +/- 1204 dollars. CONCLUSIONS: This is the first report on health service use by women smokers with cardiovascular disease. Data collection using a telephone interview guide proved feasible for evaluating health service use. The greatest costs resulted from hospital admissions and physician and emergency-room visits. Considering the high prevalence of risk factors in this cohort, secondary prevention services were severely underutilized. By increasing referrals to such services, physicians and nurses might influence women to reduce their risk for subsequent cardiovascular disease.

Caracterização de um grupo de idosas hospitalizadas e seus cuidadores visando o cuidado pós alta hospitalar / Caracterización de un grupo de ancianas hospitalizadas y sus cuidadores con vistas al cuidado post-alta hospitalaria / Characterization for a group of hospitalized old women and their cares vising the care after discharge

No presente estudo foram estudadas 50 idosas internadas em unidade de clínica médica e seus respectivos cuidadores. Verificou-se que a maioria das idosas apresentavam dependências diversas e, portanto, necessitavam da presença de um cuidador para sua sobrevivência. Os cuidadores, em sua maioria, eram do sexo feminino, pertenciam à família da idosa, tinham algum grau de escolaridade e apontaram diversas dificuldades no cuidado da mesma. Constata-se, portanto, que durante a hospitalização, há necessidade de se adotarem medidas visando ao preparo do cuidador para assumir a complexa assistência requerida pelo idoso, principalmente após a alta hospitalar.

In the present study 50 old women interned in a medical treatment unity and their respective caregivers were studied. It was verified that most of the women preseted various dependencies and, threfore, they needed the presence of a caregiver for their survival. The caregivers, most of them female, belonged to the old women's family, had some scholarship degree and pointed out several difficulties en caring for the women. It is verified, consequently, that during hospitalization there is the need to take measures aiming at preparing the caregiver to take on the complex aid required by the old person, especially after hospital discharge.
