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.

The Other Side of the Doors: Butte & Beyond -- Congressman Pat Williams “In the Crucible of Change”

Pat Williams emerged from the Mining City of Butte, Montana with a sense of grassroots, people-oriented politics. His inherent belief in the power of ordinary citizens carried him through the Montana Legislature and into Congress for a record-setting period. The accomplishments of his long career partially obscured his innate progressive and populist instinct that is reflective of the period of “in the Crucible of Change.” This film addresses Pat’s early years when his progressive instincts and activities resulted in pushback from the giant Anaconda Company which had held Montana hostage for 75 years. Pat is joined for part of the film by former campaign staffer, and now prominent media consultant, Michael Fenenbock for reflections on Pat’s 1978 “Door-to-Door to Congress” campaign, which demonstrated the power of his belief in the people on the other side of the doors. Pat Williams (b. 1937) rose from teaching grade school in his hometown of Butte, MT, to serving for the longest number of consecutive terms (9 terms, 18 years) in the US House of Representatives of anyone in Montana history. Pat was a member of the National Guard and attended UM in Missoula and William Jewel College, graduating from the University of Denver. Pat also served in the Montana legislature for 2 terms (1966 & 1968 elections). In 1969. Pat helped his legislative seat-mate John Melcher get elected as Montana’s Eastern District Congressman in the Special Election that June. Pat went to Washington DC as Melcher’s Executive Assistant. Upon returning to Montana, Pat headed up the Montana offices of the innovative Mountain Plains Family Education Program. In 1974, Pat ran unsuccessfully for Montana’s Western District Congressional seat in a three-way race with former Congressman Arnold Olsen and state Legislator Max Baucus. After the drafting and passage of the 1972 Montana Constitution, Pat was named a member of Montana’s first-ever Reapportionment Commission. In 1978 he successfully ran for Congress, conducting a massive grass-roots door-to-door campaign of 1½ years, reaching 50,000 doors. In a hotly contested 6-way Democratic primary, Pat won going away and also handily won the general election. Pat served in Congress from January, 1979 until January of 1997, 14 years representing the Western District and 4 years representing the entire state. Upon his retirement from Congress, in 1997 Williams returned to Montana where has been an instructor at the University of Montana and Senior Fellow and Regional Policy Associate at the Center for the Rocky Mountain West. He is a former member of the Montana Board of Regents and serves on a number of national education-related boards. In Congress Pat was a Deputy Whip of the U.S. House of Representatives and sat on committees on: Budget, Natural Resources, Education and Labor, and Agriculture. Pat’s leadership helped pass trailblazing legislation to assist hard-working middle-class families and ensure opportunities for every child. Pat’s fingerprints are on many pieces of important legislation, including the College Middle Income Assistance Act, the Family and Medical Leave Act, the Toddlers and Childhood Disability Act, the Library Services and Construction Act, and the Museum Services Act. Pat successfully sponsored the Lee Metcalf Wilderness Area and the Rattlesnake Wilderness area, helped save the Bob Marshall Wilderness from oil and gas exploration, and helped ban geothermal energy drilling near the borders of Yellowstone National Park. As Chairman of The Post-Secondary Education Committee, he protected the National Endowment for the Arts from elimination, a remarkable undertaking during a very trying time for the Agency. Pat worked tirelessly with Tribal College Leaders to build Montana’s seven Tribal Colleges. He was also responsible for the legislation that created The American Conservation Corps, which became the Corporation for National Service, giving thousands of America’s young people a chance to serve their country and pursue higher education. Pat lives in Missoula with his wife Carol Griffith Williams, former Montana Senate Majority Leader. They have three children and five grandchildren.

Quality of life of grown-up congenital heart disease patients after congenital cardiac surgery

BACKGROUND: Due to better early and long-term outcome, the increasing population of grown-ups with congenital heart disease (GUCH) brings up unexpected quality of life (QoL) issues. The cardiac lesion by itself is not always the major problem for these patients, since issues pertaining to QoL and psychosocial aspects often predominate. This study analyses the QoL of GUCH patients after cardiac surgery and the possible impact of medical and psychosocial complications. PATIENTS AND METHODS: A questionnaire package containing the SF-36 health survey (health related QoL), the HADS test (anxiety/depression aspects) and an additional disease specific questionnaire was sent to 345 patients (mean 26+/-11 years) operated for isolated transposition of the great arteries (TGA), tetralogy of Fallot (TOF), and ventricular septal defect (VSD). The scores were compared with age- and gender-matched standard population data and in relation to the underlying congenital heart disease (CHD). RESULTS: In all SF-36 and HADS health dimensions the GUCH patients showed excellent scores (116+/-20), which are comparable to the standard population (100+/-15), regardless of the initial CHD (p=0.12). Eighty-two percent of the patients were found to be in NYHA class I and 83% patients declared that they do not consider their QoL to be limited by their malformation. Complications like reoperations (p=0.21) and arrhythmias (p=0.10) do not show significant impact on the QoL. The additional questionnaire revealed that 76% of adult patients have a fulltime job, 18% receive a full or partial disability pension, 21% reported problems with insurances, most of them regarding health insurances (67%), and 4.4% of adult patients declared to have renounced the idea of having children due to their cardiac malformation. CONCLUSION: QoL in GUCH patients following surgical repair of isolated TOF, TGA and VSD is excellent and comparable to standard population, this without significant difference between the diagnosis groups. However, these patients are exposed to a high rate of complications and special psychosocial problems, which are not assessed by standardized questionnaires, such as the SF-36 and HADS. These findings highlight the great importance for a multidisciplinary and specialized follow-up for an adequate management of these complex patients.

Increasing Realism and Supporting Content Planning for Dynamic Scenes in a Mixed Reality System incorporating a Time-of-Flight Camera

For broadcasting purposes MIXED REALITY, the combination of real and virtual scene content, has become ubiquitous nowadays. Mixed Reality recording still requires expensive studio setups and is often limited to simple color keying. We present a system for Mixed Reality applications which uses depth keying and provides threedimensional mixing of real and artificial content. It features enhanced realism through automatic shadow computation which we consider a core issue to obtain realism and a convincing visual perception, besides the correct alignment of the two modalities and correct occlusion handling. Furthermore we present a possibility to support placement of virtual content in the scene. Core feature of our system is the incorporation of a TIME-OF-FLIGHT (TOF)-camera device. This device delivers real-time depth images of the environment at a reasonable resolution and quality. This camera is used to build a static environment model and it also allows correct handling of mutual occlusions between real and virtual content, shadow computation and enhanced content planning. The presented system is inexpensive, compact, mobile, flexible and provides convenient calibration procedures. Chroma-keying is replaced by depth-keying which is efficiently performed on the GRAPHICS PROCESSING UNIT (GPU) by the usage of an environment model and the current ToF-camera image. Automatic extraction and tracking of dynamic scene content is herewith performed and this information is used for planning and alignment of virtual content. An additional sustainable feature is that depth maps of the mixed content are available in real-time, which makes the approach suitable for future 3DTV productions. The presented paper gives an overview of the whole system approach including camera calibration, environment model generation, real-time keying and mixing of virtual and real content, shadowing for virtual content and dynamic object tracking for content planning.

Dimensions of the Ascending Aorta in Conotruncal Heart Defects

Dilatation of the ascending aorta is an important sequel in conotruncal anomalies, such as tetralogy of Fallot (TOF) or d-transposition of the great arteries (TGA). We measured dimensions and their progression at different levels of the ascending aorta in 80 patients. In TOF patients, mean z-score for aortic annulus was 1.65 (range -3.16-6.47), for sinus 1.93 (range -2.28-5.39), for st-junction 4.15 (range 0.0-8.18), and for ascending aorta 3.51 (range -1.23-6.36). Over time, annulus z-scores increased in the univariate analysis [0.07/year, 95 % confidence interval (CI) 0.01-0.14; p = 0.02], and this was unique to male patients (0.08/year, 95 % CI 0.00-0.15; p = 0.05). z-scores of the ascending aorta decreased (-0.1/year, 95 % CI -0.18 to -0.02; p = 0.02), and this was confined to patients without aortic regurgitation (AR; -0.09/year, 95 % CI -0.18 to -0.01; p = 0.04). In TGA, mean z-score for the aortic annulus was 2.13 (range -3.71-8.39), for sinus 1.77 (range -3.04-6.69), for st-junction 1.01 (range -5.44-6.71), and for ascending aorta 0.82 (range -4.91-6.46). In bivariate analysis, annulus z-scores decreased in females (-0.14/year, 95 % CI -0.25 to -0.03; p = 0.01) and in patients without AR (-0.07/year, 95 % CI -0.14-0.0; p = 0.03). z-scores of the ascending aorta increased significantly in males (0.08/year, 95 % CI 0.0 to 0.16; p = 0.05) and in patients with AR (0.12/year, 95 % CI 0.03-0.21; p = 0.01). In conclusion, TOF and TGA z-scores of the ascending aorta differ significantly from those of the normal population. Progression of z-scores over time is influenced by diagnosis, sex, and presence of AR.

Non-phenotypic tests to detect and characterize antibiotic resistance mechanisms in Enterobacteriaceae

In the past 2 decades, we have observed a rapid increase of infections due to multidrug-resistant Enterobacteriaceae. Regrettably, these isolates possess genes encoding for extended-spectrum β-lactamases (e.g., blaCTX-M, blaTEM, blaSHV) or plasmid-mediated AmpCs (e.g., blaCMY) that confer resistance to last-generation cephalosporins. Furthermore, other resistance traits against quinolones (e.g., mutations in gyrA and parC, qnr elements) and aminoglycosides (e.g., aminoglycosides modifying enzymes and 16S rRNA methylases) are also frequently co-associated. Even more concerning is the rapid increase of Enterobacteriaceae carrying genes conferring resistance to carbapenems (e.g., blaKPC, blaNDM). Therefore, the spread of these pathogens puts in peril our antibiotic options. Unfortunately, standard microbiological procedures require several days to isolate the responsible pathogen and to provide correct antimicrobial susceptibility test results. This delay impacts the rapid implementation of adequate antimicrobial treatment and infection control countermeasures. Thus, there is emerging interest in the early and more sensitive detection of resistance mechanisms. Modern non-phenotypic tests are promising in this respect, and hence, can influence both clinical outcome and healthcare costs. In this review, we present a summary of the most advanced methods (e.g., next-generation DNA sequencing, multiplex PCRs, real-time PCRs, microarrays, MALDI-TOF MS, and PCR/ESI MS) presently available for the rapid detection of antibiotic resistance genes in Enterobacteriaceae. Taking into account speed, manageability, accuracy, versatility, and costs, the possible settings of application (research, clinic, and epidemiology) of these methods and their superiority against standard phenotypic methods are discussed.

Phenotypic and genotypic identification of streptococci and related bacteria isolated from bovine intramammary infections.

BACKGROUND Streptococcus spp. and other Gram-positive, catalase-negative cocci (PNC) form a large group of microorganisms which can be found in the milk of cows with intramammary infection. The most frequently observed PNC mastitis pathogens (major pathogens) are Streptococcus uberis, Strep. dysgalactiae, and Strep. agalactiae. The remaining PNC include a few minor pathogens and a large nonpathogenic group. Improved methods are needed for the accurate identification and differentiation of PNC. A total of 151 PNC were collected from cows with intramammary infection and conclusively identified by 16S rRNA sequencing as reference method. Nine phenotypic microbiological tests (alpha-hemolysis, CAMP reaction, esculin hydrolysis, growth on kanamycin esculin azide agar and on sodium chloride agar, inulin fermentation, hippurate hydrolysis, leucine aminopeptidase and pyrrolidonyl peptidase activity), multiplex PCR for the three major pathogens (target genes for Strep. uberis, Strep. dysgalactiae and Strep. agalactiae: pauA, 16S rRNA, and sklA3, respectively), and mass spectroscopy using the matrix-assisted laser desorption ionization-time of flight (MALDI-TOF MS) were evaluated for the diagnosis and discrimination of the three clinically most relevant PNC. RESULTS The probability that a strain of Strep. uberis, Strep. dysgalactiae and Strep. agalactiae was correctly identified by combining the results of the 9 phenotypic tests was 92%, 90%, and 100%, respectively. Applying the multiplex PCR, all strains of the three major pathogens were correctly identified and no false positive results occurred. Correct identification was observed for all strains of Strep. uberis and Strep. agalactiae using MALDI-TOF MS. In the case of Strep. dysgalactiae, some variability was observed at the subspecies level, but all strains were allocated to one single cluster. CONCLUSIONS The results of the present study show that reliable identification of the clinically most relevant PNC (Strep. uberis, Strep. agalactiae and Strep. dysgalactiae) can be obtained by use of a combination of colony morphology, hemolysis type and catalase reaction, and a multiplex PCR with specific primers restricted to these 3 pathogens. The MALDI-TOF MS is a fast method that shows promising results, although identification of Strep. dysgalactiae at the subspecies level is not yet satisfactory.

BVDV: a pestivirus inducing tolerance of the innate immune response

Animals persistently infected (PI) with bovine viral diarrhea virus (BVDV) retain a strain-specific B- and T-cell immunotolerance. Pestiviral RNA triggers interferon (IFN) synthesis, and the viral RNase E(rns) inhibits IFN expression induced by extracellular viral RNA. In addition, N(pro) promotes the degradation of the transcription factor IRF-3, which effectively blocks IFN expression in BVDV-infected cells. As not all the potential target cells are infected in PI animals, these are 'chimeric' with respect to BVDV. This suggests that N(pro) and E(rns) are non-redundant IFN antagonists that act in infected and non-infected cells, respectively. Moreover, E(rns) may take a paradoxical function, both as virulence as well as "attenuation" factor: The former by preventing the activation of the innate and, consequently, of the adaptive immune system, the latter by minimizing the detrimental effects of systemic IFN production. Thus, BVDV maintains "self-tolerance" by avoiding the induction of IFN while itself being largely resistant to it without, however, interfering with the IFN action against unrelated viruses ('nonself'). This unique extension of 'self' to a virus suggests that the host's own RNases may have evolved as a guard against inadvertent activation of the innate immune system by host RNA, thus establishing a state of "innate tolerance".

Genetic testing for TMEM154 mutations associated with lentivirus susceptibility in sheep.

In sheep, small ruminant lentiviruses cause an incurable, progressive, lymphoproliferative disease that affects millions of animals worldwide. Known as ovine progressive pneumonia virus (OPPV) in the U.S., and Visna/Maedi virus (VMV) elsewhere, these viruses reduce an animal's health, productivity, and lifespan. Genetic variation in the ovine transmembrane protein 154 gene (TMEM154) has been previously associated with OPPV infection in U.S. sheep. Sheep with the ancestral TMEM154 haplotype encoding glutamate (E) at position 35, and either form of an N70I variant, were highly-susceptible compared to sheep homozygous for the K35 missense mutation. Our current overall aim was to characterize TMEM154 in sheep from around the world to develop an efficient genetic test for reduced susceptibility. The average frequency of TMEM154 E35 among 74 breeds was 0.51 and indicated that highly-susceptible alleles were present in most breeds around the world. Analysis of whole genome sequences from an international panel of 75 sheep revealed more than 1,300 previously unreported polymorphisms in a 62 kb region containing TMEM154 and confirmed that the most susceptible haplotypes were distributed worldwide. Novel missense mutations were discovered in the signal peptide (A13V) and the extracellular domains (E31Q, I74F, and I102T) of TMEM154. A matrix-assisted laser desorption/ionization-time-of flight mass spectrometry (MALDI-TOF MS) assay was developed to detect these and six previously reported missense and two deletion mutations in TMEM154. In blinded trials, the call rate for the eight most common coding polymorphisms was 99.4% for 499 sheep tested and 96.0% of the animals were assigned paired TMEM154 haplotypes (i.e., diplotypes). The widespread distribution of highly-susceptible TMEM154 alleles suggests that genetic testing and selection may improve the health and productivity of infected flocks.

Phosphorylation of the proline-rich domain of Xp95 modulates Xp95 interaction with partner proteins.

The mammalian adaptor protein Alix [ALG-2 (apoptosis-linked-gene-2 product)-interacting protein X] belongs to a conserved family of proteins that have in common an N-terminal Bro1 domain and a C-terminal PRD (proline-rich domain), both of which mediate partner protein interactions. Following our previous finding that Xp95, the Xenopus orthologue of Alix, undergoes a phosphorylation-dependent gel mobility shift during progesteroneinduced oocyte meiotic maturation, we explored potential regulation of Xp95/Alix by protein phosphorylation in hormone-induced cell cycle re-entry or M-phase induction. By MALDI-TOF (matrix-assisted laser-desorption ionization-time-of-flight) MS analyses and gel mobility-shift assays, Xp95 is phosphorylated at multiple sites within the N-terminal half of the PRD during Xenopus oocyte maturation, and a similar region in Alix is phosphorylated in mitotically arrested but not serum-stimulated mammalian cells. By tandem MS, Thr745 within this region, which localizes in a conserved binding site to the adaptor protein SETA [SH3 (Src homology 3) domain-containing, expressed in tumorigenic astrocytes] CIN85 (a-cyano-4-hydroxycinnamate)/SH3KBP1 (SH3-domain kinase-binding protein 1), is one of the phosphorylation sites in Xp95. Results from GST (glutathione S-transferase)-pull down and peptide binding/competition assays further demonstrate that the Thr745 phosphorylation inhibits Xp95 interaction with the second SH3 domain of SETA. However, immunoprecipitates of Xp95 from extracts of M-phase-arrested mature oocytes contained additional partner proteins as compared with immunoprecipitates from extracts of G2-arrested immature oocytes. The deubiquitinase AMSH (associated molecule with the SH3 domain of signal transducing adaptor molecule) specifically interacts with phosphorylated Xp95 in M-phase cell lysates. These findings establish that Xp95/Alix is phosphorylated within the PRD during M-phase induction, and indicate that the phosphorylation may both positively and negatively modulate their interaction with partner proteins.

Imaging findings in uncorrected tetralogy of Fallot and pulmonary atresia with major aortopulmonary collateral arteries and septic embolism.

Tetralogy of Fallot (TOF) is one of the most common congenital heart malformations comprising a ventricular septal defect, right ventricular outflow tract obstruction, right ventricular hypertrophy, and overriding aorta. A rare variant includes pulmonary atresia and major aortopulmonary collateral arteries. Altered hemodynamics within the functional single-ventricle results in turbulent flow and predisposes to endocardial vegetation formation which may consequently lead to thromboembolic events. We present a rare case of an adult survivor of uncorrected TOF with pulmonary atresia.
