Reorganization of secondary and tertiary health care levels: impact on the outcomes of oral cancer screening in the São Paulo State, Brazil

This study presents the strategies for prevention and early detection of oral cancer by means of screening in the elderly population of São Paulo, the richest and the most populous state of Brazil. This research was a retrospective longitudinal study based on the analysis of secondary data. The variables - number of participating cities, coverage of screening, and number of suspicious and confirmed cases of oral cancer - were divided into two periods: 2001-2004 and 2005-2008. Data were analyzed statistically by the chi-square test at 5% significance level. The implementation of a nationwide public oral health policy in 2004 and the reorganization of the secondary and tertiary health care were evaluated as mediator factors able to interfere in the achieved outcomes. From 2001 to 2008, 2,229,273 oral examinations were performed. There was an addition of 205 participating cities by the end of the studied period (p<0.0001). The coverage of oral cancer screening increased from 4.1% to 16% (p<0.0001). There was a decrease in the number of suspicious lesions (from 9% in 2005 to 5% in 2008) (p<0.0001) and in the rate of confirmed oral cancer cases per 100,000 examinations (from 20.89 in 2001 to 10.40 in 2008) (p<0.0001). After 8 years of screening, there was a decrease in the number of suspicious lesions and confirmed cases of oral cancer in the population. The reorganization of secondary and tertiary health care levels of oral care seems to have contributed to modify these numbers, having a positive impact on the outcomes of oral cancer screening in the São Paulo State.

Editorial reorganization of an alphabetically ordered collection of short stories: analysis of problems and hypothesis of possible solutions

This paper aims to show, analyze and solve the problems related to the translation of the book with meaning-bond alphabetically ordered chapter titles La vita non è in ordine alfabetico, by the Italian writer Andrea Bajani. The procedure is inevitable for a possible translation of the book, and it is necessary to have a preliminary pattern to follow. After translating the whole book, not only is a revision fundamental, but a restructure and reorganization of the collection may be required, hence, what this thesis offers is a scheme to start from, together with an analysis of the possible problems that may arise, and a useful method to find a solution.

Dynamic reorganization of flotillins in chemokine-stimulated human T-lymphocytes

Different types of membrane microdomains (rafts) have been postulated to be present in the rear and front of polarized migrating T-lymphocytes. Disruption of rafts by cholesterol sequestration prevents T-cell polarization and migration. Reggie/flotillin-1 and -2 are two highly homologous proteins that are thought to shape membrane microdomains. We have previously demonstrated the enrichment of flotillins in the uropod of human neutrophils. We have now investigated mechanisms involved in chemokine-induced flotillin reorganization in human T-lymphocytes, and possible roles of flotillins in lymphocyte polarization.

Hostile takeover by Plasmodium: reorganization of parasite and host cell membranes during liver stage egress

The protozoan parasite Plasmodium is transmitted by female Anopheles mosquitoes and undergoes obligatory development within a parasitophorous vacuole in hepatocytes before it is released into the bloodstream. The transition to the blood stage was previously shown to involve the packaging of exoerythrocytic merozoites into membrane-surrounded vesicles, called merosomes, which are delivered directly into liver sinusoids. However, it was unclear whether the membrane of these merosomes was derived from the parasite membrane, the parasitophorous vacuole membrane or the host cell membrane. This knowledge is required to determine how phagocytes will be directed against merosomes. Here, we fluorescently label the candidate membranes and use live cell imaging to show that the merosome membrane derives from the host cell membrane. We also demonstrate that proteins in the host cell membrane are lost during merozoite liberation from the parasitophorous vacuole. Immediately after the breakdown of the parasitophorous vacuole membrane, the host cell mitochondria begin to degenerate and protein biosynthesis arrests. The intact host cell plasma membrane surrounding merosomes allows Plasmodium to mask itself from the host immune system and bypass the numerous Kupffer cells on its way into the bloodstream. This represents an effective strategy for evading host defenses before establishing a blood stage infection.

Cognitive impairment and cortical reorganization in children with benign epilepsy with centrotemporal spikes

Benign epilepsy with centrotemporal spikes (BECTS) is associated with mild cognitive deficits, especially language impairment. This study aimed to clarify whether children with BECTS with left- or right-hemispheric, or bilateral focus have specific neuropsychological language deficits when compared to healthy controls, whether these deficits correlate functionally with language network organization (typical vs. atypical), and whether cofactors such as duration, handedness, and medication have a relevant impact on language reorganization processes.

Cortical reorganization after brain damage: the oculomotor model

Recovery from eye movement deficits after cortical lesions is amazingly rapid and almost complete, which is in sharp contrast to most other neurological deficits of cerebral lesions. The underlying mechanisms of this successful recovery remain uncertain. We had the rare opportunity to examine two patients with recovery from saccade deficits after a lesion restricted to the frontal eye field (FEF) by means of transcranial magnetic stimulation (TMS). The results provide direct evidence that recovery depended on the integrity of the oculomotor regions of the nonlesioned contralesional hemisphere, and that the compensatory network is task-specific.

Reorganization of CA3 area of the mouse hippocampus after pilocarpine induced temporal lobe epilepsy with special reference to the CA3-septum pathway

We showed that when CA3 pyramidal neurons in the caudal 80% of the dorsal hippocampus had almost disappeared completely, the efferent pathway of CA3 was rarely detectable. We used the mouse pilocarpine model of temporal lobe epilepsy (TLE), and injected iontophoretically the anterograde tracer phaseolus vulgaris leucoagglutinin (PHA-L) into gliotic CA3, medial septum and the nucleus of diagonal band of Broca, median raphe, and lateral supramammillary nuclei, or the retrograde tracer cholera toxin B subunit (CTB) into gliotic CA3 area of hippocampus. In the afferent pathway, the number of neurons projecting to CA3 from medial septum and the nucleus of diagonal band of Broca, median raphe, and lateral supramammillary nuclei increased significantly. In the hippocampus, where CA3 pyramidal neurons were partially lost, calbindin, calretinin, parvalbumin immunopositive back-projection neurons from CA1-CA3 area were observed. Sprouting of Schaffer collaterals with increased number of large boutons in both sides of CA1 area, particularly in the stratum pyramidale, was found. When CA3 pyramidal neurons in caudal 80% of the dorsal hippocampus have almost disappeared completely, surviving CA3 neurons in the rostral 20% of the dorsal hippocampus may play an important role in transmitting hyperactivity of granule cells to surviving CA1 neurons or to dorsal part of the lateral septum. We concluded that reorganization of CA3 area with its downstream or upstream nuclei may be involved in the occurrence of epilepsy.

Regulation of endothelial cell cytoskeletal reorganization by a secreted frizzled-related protein-1 and frizzled 4- and frizzled 7-dependent pathway: role in neovessel formation

Consistent with findings of Wnt pathway members involved in vascular cells, a role for Wnt/Frizzled signaling has recently emerged in vascular cell development. Among the few Wnt family members implicated in vessel formation in adult, Wnt7b and Frizzled 4 have been shown as involved in vessel formation in the lung and in the retina, respectively. Our previous work has shown a role for secreted Frizzled-related protein-1 (sFRP-1), a proposed Wnt signaling inhibitor, in neovascularization after an ischemic event and demonstrated its role as a potent angiogenic factor. However the mechanisms involved have not been investigated. Here, we show that sFRP-1 treatment increases endothelial cell spreading on extracellular matrix as revealed by actin stress fiber reorganization in an integrin-dependent manner. We demonstrate that sFRP-1 can interact with Wnt receptors Frizzled 4 and 7 on endothelial cells to transduce downstream to cellular machineries requiring Rac-1 activity in cooperation with GSK-3beta. sFRP-1 overexpression in endothelium specifically reversed the inactivation of GSK-3 beta and increased neovascularization in ischemia-induced angiogenesis in mouse hindlimb. This study illustrates a regulated pathway by sFRP-1 involving GSK-3beta and Rac-1 in endothelial cell cytoskeletal reorganization and in neovessel formation.

Executive Reorganization: Building a State Government That Worked for People -- Tom Harrison, Diana Dowling & Sheena Wilson “In the Crucible of Change”

One of the primary accomplishments of Governor Forrest Anderson in 1969-71 was the reorganization of the Executive Branch of Montana government, something that had been attempted six different times between 1919 and 1962 as state government had grown from twenty agencies to almost 200 uncontrolled boards, bureaus and commissions. The chaotic structure of the executive branch disempowered governors of both parties and empowered the private corporations and organizations that were the power structure of Montana. With remarkable political acumen, Governor Anderson figured out how to get that near impossible job done. Central to his efforts was the creation of an Executive Reorganization Commission, including eight legislators and the Governor, the adoption of a Constitutional Amendment that limited the executive branch to no more than twenty departments under the Governor, and the timely completion of a massive research effort to delineate the actual structure of the twenty departments. That story is told in this episode by three major players in the effort, all involved directly with the Executive Reorganization Commission: Tom Harrison, Diana Dowling and Sheena Wilson. Their recollections reflect an insider’s perspective of this significant accomplishment that helped change Montana “In the Crucible of Change.” Tom Harrison is a former Republican State Representative and State Senator from Helena, who was a member of the Executive Reorganization Commission. As Majority Leader in the Montana House of Representatives in 1971, he was the primary sponsor of the House’s executive reorganization bill and helped shepherd the Senate’s version to passage. Harrison was the Republican candidate for Attorney General in 1976 after which he practiced private law for 3 more decades. He served in the Montana Army National Guard for almost 34 years, rising to the rank of Colonel in the position of Judge Advocate General. He was a founding Director of Federal Defenders of Montana (legal representation for indigents accused within the Federal Judicial System); appointed Chairman of the original Montana State Fund (workers' compensation insurance) by Gov. Stephens; served as President of the Montana Trial Lawyers Association, Helena Kiwanis Club and St. Peter's Community Hospital Foundation, as well as Chairman and Director of AAA MountainWest; and was a founder, first Chairman and Director of the Valley Bank of Helena for over 25 years. Diana Dowling was an attorney for the Executive Reorganization Commission and helped draft the legislation that was passed. She also worked for Governor Forrest Anderson and for the 1972 Constitutional Convention where she prepared and directed publication of official explanation of the new Constitution that was mailed to all Montana voters. Diana was Executive Director of the Montana Bar Association and for 20 years held various legal positions with the Montana Legislative Council. For 12 years she was a commissioner on the National Conference of Commissioners on Uniform State Laws and for 7 years was a member of Montana State Board of Bar Examiners. Diana was the first director of the Montana Lottery, an adjunct professor at both Carroll College and the UM Law School, and an administrative officer for Falcon Press Publishing Co. Diana is currently - and intends to continue being - a perpetual college student. Sheena Wilson came fresh out of the University of Montana to become a Research Assistant for the Executive Reorganization Commission. Later she worked for seven years as a field representative in Idaho and Montana for the Mountain Plains Family Education Program, for thirteen years with Congressman Pat Williams as Executive Assistant in Washington and Field Assistant here in Montana, owned and managed a Helena restaurant for seven years, worked as Executive Assistant for State Auditor John Morrison and was Deputy Chief of Staff for Governor Brian Schweitzer his full 8 years in the Governorship. Though currently “retired”, Sheena serves on the Montana Board of Investments, the Public Employees Retirement Board and the Capitol Complex Advisory Council and is a partner in a dry-land wheat farm in Teton County that was homesteaded by her great uncle.
