Development of a Sustainable Water Resource for the Big Creek Watershed

Proceedings of the 2001 Georgia Water Resources Conference, April 26 and 27, 2001, Athens, Georgia.The Big Creek Water Quality Management Plan has been a cooperative effort of Cherokee, Forsyth and Fulton Counties, as well as the Cities of Alpharetta, Cumming and Roswell to develop a mutually agreeable water quality protection Plan for the Big Creek Watershed. The Big Creek Watershed straddles the rapidly growing Georgia 400 Corridor in the northern part of Metropolitan Atlanta. It is a water supply for the City of Roswell and has an area of about 99 square miles at the Roswell water intake. The project purposes included: achieving and maintaining a high quality water supply; minimizing flooding, property damage and stream impacts; protecting wetlands and establish greenways; meeting minimum Georgia DNR water supply watershed criteria or developing acceptable alternatives; understanding the impacts of urbanization; and considering options for and developing multi jurisdictional cooperation. The study encompassed watershed characterization, assessment of water quality and quantity issues, assessment of habitat and social issues and the selection of best management practices (BMP's) to meet water quality, water quantity, habitat and social goals. Study tasks included forecasting future land use and impervious areas, assessing current and future impacts and evaluating alternate management and protection scenarios.Sponsored and Organized by: U.S. Geological Survey, Georgia Department of Natural Resources, Natural Resources Conservation Service, The University of Georgia, Georgia State University, Georgia Institute of TechnologyThis book was published by the Institute of Ecology, The University of Georgia, Athens, Georgia 30602-2202.

Sex Differences in Obesity-Induced Inflammation

Obesity is defined as a BMI greater than 25 kg/m2. Once thought to simply be a nutritional disorder, obesity has become a major health concern characterized by a state of constant low-grade inflammation caused by chronic adiposity. This state of inflammation is characterized by circulating inflammatory mediators, such as IL-6, leptin, and TNF-α, as well as varying levels of glucose-regulating hormones produced by obese adipose tissue. When left untreated, obesity can lead to a number of diseases including, but not limited to, cardiovascular disease, metabolic syndrome, neurodegeneration, type II diabetes mellitus, chronic kidney disease, and infertility. The distribution of adiposity differs in men and women, and these differences, along with the differences in sex hormones and sex hormone levels, can exacerbate or attenuate the course of disease pathology. Obesity can also be exacerbated by stress, which can worsen disease pathogenesis. In this review, we will explore how obesity affects inflammation and disease and how sex can affect the course of these diseases

Bapineuzumab for mild to moderate Alzheimer’s disease in two global, randomized, phase 3 trials

Background Our objective was to evaluate the efficacy (clinical and biomarker) and safety of intravenous bapineuzumab in patients with mild to moderate Alzheimer’s disease (AD). Methods Two of four phase 3, multicenter, randomized, double-blind, placebo-controlled, 18-month trials were conducted globally: one in apolipoprotein E ε4 carriers and another in noncarriers. Patients received bapineuzumab 0.5 mg/kg (both trials) or 1.0 mg/kg (noncarrier trial) or placebo every 13 weeks. Coprimary endpoints were change from baseline to week 78 on the 11-item Alzheimer’s Disease Assessment Scale–Cognitive subscale and the Disability Assessment for Dementia. Results A total of 683 and 329 patients completed the current carrier and noncarrier trials, respectively, which were terminated prematurely owing to lack of efficacy in the two other phase 3 trials of bapineuzumab in AD. The current trials showed no significant difference between bapineuzumab and placebo for the coprimary endpoints and no effect of bapineuzumab on amyloid load or cerebrospinal fluid phosphorylated tau. (Both measures were stable over time in the placebo group.) Amyloid-related imaging abnormalities with edema or effusion were confirmed as the most notable adverse event. Conclusions These phase 3 global trials confirmed lack of efficacy of bapineuzumab at tested doses on clinical endpoints in patients with mild to moderate AD. Some differences in the biomarker results were seen compared with the other phase 3 bapineuzumab trials. No unexpected adverse events were observed. Trial registration Noncarriers (3000) ClinicalTrials.gov identifier NCT00667810; registered 24 Apr 2008. Carriers (3001) ClinicalTrials.gov identifier NCT00676143; registered 2 May 2008

Protocol of the Cognitive Health in Ageing Register: Investigational, Observational and Trial Studies in Dementia Research (CHARIOT): Prospective Readiness cOhort (PRO) SubStudy

The Cognitive Health in Ageing Register: Investigational, Observational and Trial Studies in Dementia Research (CHARIOT): Prospective Readiness cOhort (PRO) SubStudy (CPSS), sponsored by Janssen Pharmaceutical Research & Development LLC, is an Alzheimer's disease (AD) biomarker enriched observational study that began 3 July 2015 CPSS aims to identify and validate determinants of AD, alongside cognitive, functional and biological changes in older adults with or without detectable evidence of AD pathology at baseline. CPSS is a dual-site longitudinal cohort (3.5 years) assessed quarterly. Cognitively normal participants (60-85 years) were recruited across Greater London and Edinburgh. Participants are classified as high, medium (amnestic or non-amnestic) or low risk for developing mild cognitive impairment-Alzheimer's disease based on their Repeatable Battery for the Assessment of Neuropsychological Status performance at screening. Additional AD-related assessments include: a novel cognitive composite, the Global Preclinical Alzheimer's Cognitive Composite, brain MRI and positron emission tomography and cerebrospinal fluid analysis. Lifestyle, other cognitive and functional data, as well as biosamples (blood, urine, and saliva) are collected. Primarily, study analyses will evaluate longitudinal change in cognitive and functional outcomes. Annual interim analyses for descriptive data occur throughout the course of the study, although inferential statistics are conducted as required. CPSS received ethical approvals from the London-Central Research Ethics Committee (15/LO/0711) and the Administration of Radioactive Substances Advisory Committee (RPC 630/3764/33110) The study is at the forefront of global AD prevention efforts, with frequent and robust sampling of the well-characterised cohort, allowing for detection of incipient pathophysiological, cognitive and functional changes that could inform therapeutic strategies to prevent and/or delay cognitive impairment and dementia. Dissemination of results will target the scientific community, research participants, volunteer community, public, industry, regulatory authorities and policymakers. On study completion, and following a predetermined embargo period, CPSS data are planned to be made accessible for analysis to facilitate further research into the determinants of AD pathology, onset of symptomatology and progression. The CHARIOT:PRO SubStudy is registered with clinicaltrials.gov (NCT02114372). Notices of protocol modifications will be made available through this trial registry.

Skuteczność i bezpieczeństwo leczenia toksyną botulinową typu A (abobotulinum toxin A) pacjentów ze spastycznością kończyny dolnej. Randomizowane badanie kliniczne

Cel: Wykazanie skuteczności jednorazowego wstrzyknięcia toksy­ny botulinowej typu A (abobotulinum toxin A [Dysport]) podawanej do mięśni kończyny dolnej w porównaniu z placebo u dorosłych z przewlekłym niedowładem połowiczym. Ocena długotrwałego bezpieczeństwa i skuteczności wielokrotnych wstrzyknięć. Metody: W wieloośrodkowym badaniu klinicznym prowadzonym metodą podwójnie ślepej próby, z randomizacją, kontrolą placebo i pojedynczym cyklem leczenia dorośli uczestnicy po co najmniej 6 miesiącach od udaru/uszkodzenia mózgu otrzymali pojedynczą iniekcję badanego leku (abobotulinum toxin A 1000 j., 1500 j., placebo) do mięśni kończyny dolnej. Po badaniu zasadniczym badanie przedłużono o rok w fazie otwartej, w trakcie której uczestnicy otrzymywali nie więcej niż 4 cykle leczenia (1000 j., 1500 j.) podawane w co najmniej 12-tygodniowych odstępach. Skuteczność leczenia oceniano według zmodyfikowanej skali Ashwortha (MAS, Modified Ashworth Scale) dla kompleksu mięśnia trójgłowego łydki (GSC, gastrocnemius-soleus complex; pierwszorzędowy punkt końcowy badania metodą podwójnie śle­pej próby). W badaniu określono również odpowiedź na leczenie w łącznej ocenie lekarzy (PGA, physician global assessment), a także szybkość swobodnego chodu boso. Bezpieczeństwo leczenia stanowiło pierwszorzędowy punkt końcowy badania prowadzonego metodą próby otwartej. Wyniki: Średnia zmiana (95-proc. przedział ufności) wartości MAS GSC w okresie od początku do 4. tygodnia (faza leczenia metodą podwójnie ślepej próby, n = 381) po jednokrotnym podaniu leku wyniosła: –0,5 (od –0,7 do –0,4) (placebo, n = 128), –0,6 (od –0,8 do –0,5) (toksyna botulinowa typu A 1000 j., n = 125; p = = 0,28 wobec placebo) i –0,8 (od –0,9 do –0,7) (toksyna abobotu­linowa typu A 1500 j., n = 128; p = 0,009 wobec placebo). Średnie wartości oceny PGA w 4. tygodniu były następujące: 0,7 (0,5–0,9) (placebo), 0,9 (0,7–1,1) (1000 j.; p = 0,067 wobec placebo) i 0,9 (0,7–1,1) (1500 j.; p = 0,067). Szybkość chodu nie poprawiła się statystycznie znamiennie w porównaniu z placebo. W 4. tygodniu 4. cyklu leczenia (faza otwarta) średnia zmiana oceny MAS GSC wyniosła –1,0. W cyklach badania w fazie otwartej odnotowano stopniową poprawę oceny PGA i szybkości chodu. W 4. tygodniu 4. cyklu leczenia średnia ocena PGA wyniosła 1,9, a szybkość chodu wzrosła o 25,3% (17,5–33,2), przy czym 16% uczestni­ków badania osiągnęło szybkość ponad 0,8 m/s (odpowiadającą chodowi samodzielnemu; 0% na początku badania). Tolerancja leczenia była dobra i zgodna ze znanym profilem bezpieczeństwa toksyny abobotulinowej typu A. Wnioski: Wśród pacjentów z przewlekłym niedowładem po­łowiczym jednokrotne podanie toksyny abobotulinowej typu A (Dysport, Ipsen) spowodowało obniżenie napięcia mięśniowego. Wielokrotne podanie leku w fazie rocznego przedłużenia badania zasadniczego było dobrze tolerowane oraz przyczyniło się do zwiększenia szybkości chodu i prawdopodobieństwa osiągnięcia chodu samodzielnego. Numery identyfikacyjne na portalu Clinicaltrial.gov: NCT01249404, NCT01251367. Klasyfikacja dowodu naukowego: z fazy badania prowadzonej metodą podwójnie ślepej próby uzyskano dane naukowe klasy I, na podstawie których stwierdza się, że jednokrotne wstrzyknięcie toksyny botulinowej typu A u dorosłych z przewlekłym niedowładem spastycznym zmniejsza napięcie mięśniowe w kończynie dolnej.

High-throughput mutational analysis of TOR1A in primary dystonia

<p>Abstract</p> <p>Background</p> <p>Although the c.904_906delGAG mutation in Exon 5 of <it>TOR1A </it>typically manifests as early-onset generalized dystonia, DYT1 dystonia is genetically and clinically heterogeneous. Recently, another Exon 5 mutation (c.863G>A) has been associated with early-onset generalized dystonia and some ΔGAG mutation carriers present with late-onset focal dystonia. The aim of this study was to identify <it>TOR1A </it>Exon 5 mutations in a large cohort of subjects with mainly non-generalized primary dystonia.</p> <p>Methods</p> <p>High resolution melting (HRM) was used to examine the entire <it>TOR1A </it>Exon 5 coding sequence in 1014 subjects with primary dystonia (422 spasmodic dysphonia, 285 cervical dystonia, 67 blepharospasm, 41 writer's cramp, 16 oromandibular dystonia, 38 other primary focal dystonia, 112 segmental dystonia, 16 multifocal dystonia, and 17 generalized dystonia) and 250 controls (150 neurologically normal and 100 with other movement disorders). Diagnostic sensitivity and specificity were evaluated in an additional 8 subjects with known ΔGAG DYT1 dystonia and 88 subjects with ΔGAG-negative dystonia.</p> <p>Results</p> <p>HRM of <it>TOR1A </it>Exon 5 showed high (100%) diagnostic sensitivity and specificity. HRM was rapid and economical. HRM reliably differentiated the <it>TOR1A </it>ΔGAG and c.863G>A mutations. Melting curves were normal in 250/250 controls and 1012/1014 subjects with primary dystonia. The two subjects with shifted melting curves were found to harbor the classic ΔGAG deletion: 1) a non-Jewish Caucasian female with childhood-onset multifocal dystonia and 2) an Ashkenazi Jewish female with adolescent-onset spasmodic dysphonia.</p> <p>Conclusion</p> <p>First, HRM is an inexpensive, diagnostically sensitive and specific, high-throughput method for mutation discovery. Second, Exon 5 mutations in <it>TOR1A </it>are rarely associated with non-generalized primary dystonia.</p

Publisher Copyright: © 2021 Society of Biological PsychiatryBackground: Posttraumatic stress disorder (PTSD) is heritable and a potential consequence of exposure to traumatic stress. Evidence suggests that a quantitative approach to PTSD phenotype measurement and incorporation of lifetime trauma exposure (LTE) information could enhance the discovery power of PTSD genome-wide association studies (GWASs). Methods: A GWAS on PTSD symptoms was performed in 51 cohorts followed by a fixed-effects meta-analysis (N = 182,199 European ancestry participants). A GWAS of LTE burden was performed in the UK Biobank cohort (N = 132,988). Genetic correlations were evaluated with linkage disequilibrium score regression. Multivariate analysis was performed using Multi-Trait Analysis of GWAS. Functional mapping and annotation of leading loci was performed with FUMA. Replication was evaluated using the Million Veteran Program GWAS of PTSD total symptoms. Results: GWASs of PTSD symptoms and LTE burden identified 5 and 6 independent genome-wide significant loci, respectively. There was a 72% genetic correlation between PTSD and LTE. PTSD and LTE showed largely similar patterns of genetic correlation with other traits, albeit with some distinctions. Adjusting PTSD for LTE reduced PTSD heritability by 31%. Multivariate analysis of PTSD and LTE increased the effective sample size of the PTSD GWAS by 20% and identified 4 additional loci. Four of these 9 PTSD loci were independently replicated in the Million Veteran Program. Conclusions: Through using a quantitative trait measure of PTSD, we identified novel risk loci not previously identified using prior case-control analyses. PTSD and LTE have a high genetic overlap that can be leveraged to increase discovery power through multivariate methods.publishersversionpublishe
