Final Report: 2007 Alzheimer's Disease Task Force, January 2008

Following an overview of the history of the task force and background information on Alzheimer’s disease, the report is divided into four sections. These sections correspond to the delineation of four subcommittees into which task force members were divided. It should be noted that the term “Alzheimer’s Disease” is used to encompass not only Alzheimer’s disease but also additional brain disorders such as vascular dementia, mixed dementia, mild cognitive impairment, dementia with Lewy bodies, and other types of dementia. Interspersed throughout the report are verbatim comments received from Iowans who responded to on-line surveys about how Alzheimer’s disease has affected their lives. Their words poignantly give voice to the emotions, frustrations, and hopes of Iowans who are personally experiencing the impact of Alzheimer’s disease. The Report includes 22 recommendations to the Iowa General Assembly designed to improve the availability and quality of services for people with dementia, their caregivers, and their families. The recommendations fall into four categories; a) Education and Training; b) Services and Housing; c) Wellness and Disease Management; and, d) Funding and Reimbursement.

The rise and fall in menopausal hormone therapy and breast cancer incidence.

Studies conducted in different areas of North America and Europe showed a 5-10% decline in the incidence of breast cancer following reductions up to 70% in menopause hormone therapy (HT) use after 2002. The observation that the decline was larger in (or limited to) women aged > or =50 years weighs in favour of an effect of reduced HT use on breast cancer incidence. However, changes in screening are also likely to play a role in the decreasing incidence of breast cancer observed in several countries. In particular, the technical improvements and the increased effectiveness of breast cancer screening and detection during the 1990s led to a decreased number of pre-clinical cases found by screening in subsequent years. Further, disentangling the effects of HT use and screening is difficult, as women who stop using HT may also undergo mammography screening less frequently. Thus, the reasons of the falls in incidence remain open to discussion.

Intravenous Lacosamide for Treatment of Status Epilepticus after Failing First-Line Therapy

Rationale: Treatment of status epilepticus (SE) usually requires intravenous anticonvulsant therapy. Although there are established drugs of first choice for its treatment, potentially hazardous side effects of these agents are not uncommon. Lacosamide (LCM) is a novel anticonvulsant drug that is available as infusion solution. LCM could be an alternative for treatment of SE when the standard drugs fail or should be avoided. Methods: We retrospectively identified patients from the hospital databases of two German and one Swiss neurological departments (University Hospital Marburg, Klinikum Osnabrueck, University Hospital Lausanne) between September 1st 2008 and May 22nd 2009 who were admitted because of SE and received at least one dose of intravenous LCM for treatment of SE. Results: Seventeen patients (11 female, 6 male) were identified. Median age was 71 years. 3 patients suffered from generalized convulsive SE, 8 patients had significant reduction of awareness with or without subtle motor symptoms, 6 patients had a simple focal status without relevant reduction of awareness. Etiology was acute symptomatic in 5 patients, remote symptomatic without pre-existing epilepsy in 6 patients, remote symptomatic and pre-existing epilepsy in 5 patients, and unknown in 1 patient. LCM was administered after failure of first line therapy in all cases. The first LCM bolus was 400mg in 13 patients and 200mg in 4 patients. LCM administration stopped SE in 7 patients. In 2 of them, LCM was administered immediately after benzodiazepine administration, in the others after failure of benzodiazepines and other first-line and/or second-line drugs. In 3 patients, SE was terminated by other anticonvulsants like Phenytoin, Phenobarbital or Oxcarbazepine. In 5 patients, SE could only be terminated by intubation and application of high-dose Midazolam, Propofol and/or Thiopental. In 2 patients, SE could not be terminated in spite of high doses of barbiturates. There was no serious adverse event documented that could possibly be attributed to LCM Conclusions: Intravenous LCM may be an alternative treatment for SE after failure of benzodiazepins and other established drugs, or when such agents are considered unsuitable.

Effects of mineralocorticoid and K+ concentration on K+ secretion and ROMK channel expression in a mouse cortical collecting duct cell line.

The cortical collecting duct (CCD) plays a key role in regulated K(+) secretion, which is mediated mainly through renal outer medullary K(+) (ROMK) channels located in the apical membrane. However, the mechanisms of the regulation of urinary K(+) excretion with regard to K(+) balance are not well known. We took advantage of a recently established mouse CCD cell line (mCCD(cl1)) to investigate the regulation of K(+) secretion by mineralocorticoid and K(+) concentration. We show that this cell line expresses ROMK mRNA and a barium-sensitive K(+) conductance in its apical membrane. As this conductance is sensitive to tertiapin-Q, with an apparent affinity of 6 nM, and to intracellular acidification, it is probably mediated by ROMK. Overnight exposure to 100 nM aldosterone did not significantly change the K(+) conductance, while it increased the amiloride-sensitive Na(+) transport. Overnight exposure to a high K(+) (7 mM) concentration produced a small but significant increase in the apical membrane barium-sensitive K(+) conductance. The mRNA levels of all ROMK isoforms measured by qRT-PCR were not changed by altering the basolateral K(+) concentration but were decreased by 15-45% upon treatment with aldosterone (0.3 or 300 nM for 1 and 3 h). The paradoxical response of ROMK expression to aldosterone could possibly work as a preventative mechanism to avoid excessive K(+) loss which would otherwise result from the increased electrogenic Na(+) transport and associated depolarization of the apical membrane in the CCD. In conclusion, mCCD(cl1) cells demonstrate a significant K(+) secretion, probably mediated by ROMK, which is not stimulated by aldosterone but increased by overnight exposure to a high K(+) concentration.

Redes Eléctricas Digitais Power Line Communication :- Desafios e Oportunidades para Cabo Verde

Para distribuir e socializar a informação, nos mais diversos locais e das formas mais rápidas possíveis, proliferam as redes de comunicação de dados, cada vez mais presentes em nosso quotidiano, especialmente através do uso das novas tecnologias. Dentre elas, destaca-se a tecnologia Power Line Communication (PLC) Linha de força de comunicação, em que os dados são transmitidos através da corrente eléctrica. Hoje, um pouco por todo o mundo, estuda-se a alternativa viável, desafios e oportunidades de se utilizar a rede de energia eléctrica como um canal efectivo para transmissão de dados, voz e imagem, tornando-se assim, também uma rede de comunicação de dados. Ainda sem uma oferta comercial a funcionar em Cabo Verde, apesar de já terem sido feito algumas tentativas de testes de equipamentos, a Power Line Communication é já utilizada com sucesso em vários países, ligando em banda larga casas e empresas. Assim, este trabalho pretende fazer o enquadramento da tecnologia em si, bem como analisar os desafios e oportunidades da implementação do PLC no mercado Cabo-verdiano.

Caste polymorphism of apterous line of the Neotropical termite Nasutitermes corniger (Motschulsky) (Isoptera, Termitidae)

Termite societies are structured by individuals that can be grouped into castes and instars. The development of these instars in most species occurs in irregular patterns and sometimes is distinguished subcastes in physical systems that originate polymorphic soldiers and workers. In this study, we characterized the morphological diversity of castes of apterous in Nasutitermes corniger. We collected four colonies of N. corniger, one every three months between May 2011 and February 2012. Individuals of the nest were separated into groups: larval stages, workers and presoldiers and soldiers. A morphometric analysis was performed on individuals from each group based on head width, metatibia, antenna, and thorax length. The data were submitted to discriminant analysis to confirm different morphological types inside these groups. The apterous line of N. corniger is composed of one first larval instar and two second larval instar. The workers caste has two lines of development with four instars in a larger line and three instars in a lower line. Two morphological types were identified in presoldiers and soldiers. The pattern of castes was similar to other species of the genus, in which bifurcation into two lines of workers, one smaller and one larger occurs after the first molt.
