Governor Forrest Anderson’s Leadership & Political Acumen -- Alec Hansen “In the Crucible of Change”

Montana Governor Forrest Anderson was perhaps the most experienced and qualified person ever to be elected as Governor of Montana. Having previously served as a county attorney, a member of the legislature, a Supreme Court Justice, and twelve years as Attorney General, Anderson roared to a large victory in 1968 over the Incumbent GOP Governor Tim Babcock. Though the progressive change period in Montana began a few years earlier, Anderson’s 1968 win catapulted progressive policy-making into the mainstream of Montana political and governmental affairs. He used his unique skills and leadership to craftily architect the reorganization of the executive branch which had been kept weak since statehood so that the peoples’ government would not be able to challenge corporations who so dominated Montana. Anderson, whose “Pay More, What For?” campaign slogan strongly separated him from Tim Babcock and the GOP on the sales tax issue, not only beat back the regressive sales tax in the 1968 election, but oversaw its demise at the polls in 1971, shaping politics in Montana for decades to come. Anderson also was a strong proponent of the concept of a new Montana Constitution and contributed strategically to its calling and passage. Anderson served only one term as Governor for health reasons, but made those four years a launch pad for progressive politics and government in Montana. In this film, Alec Hansen, Special Assistant to Governor Anderson, provides an insider’s perspective as he reflects on the unique way in which Governor Anderson got things done at this critical period “In the Crucible of Change.” Alec Hansen is best known in Montana political and governmental circles as the long-time chief of the Montana League of Cities and Towns, but he cut his teeth in public service with Governor Forrest Anderson. Alec was born in Butte in 1941, attended local schools graduating from Butte High in 1959. After several years working as a miner and warehouseman for the Anaconda Company in Butte, he attended UM and graduated in History and Political Science in 1966. He joined the U.S. Navy and served with amphibious forces in Vietnam. After discharge from the Navy in 1968, he worked as a news and sports reporter for The Montana Standard in Butte until in September of 1969 he joined Governor Anderson as a Special Assistant focused on press, communications and speech-writing. Alec has noted that drafts were turned into pure Forrest Anderson remarks by the man himself. He learned at the knee of “The Fox” for the rest of Anderson’s term and continued with Governor Tom Judge for two years before returning to Butte to work for the Anaconda Company as the Director of Communications for Montana operations. In 1978, after Anaconda was acquired by the Atlantic Richfield Company, Alec went to work in February for U.S. Senator Paul Hatfield in Washington D.C., leaving after Hatfield’s primary election loss in June 1978. He went back to work for Gov. Judge, remaining until the end of 1980. In 1981 Alec worked as a contract lobbyist and news and sports reporter for the Associated Press in Helena. In 1982, the Montana League of Cities and Towns hired him as Executive Director, a position he held until retirement in 2014. Alec and his wife Colleen, are the parents of two grown children, with one grandson.

The content and composition of lipids in the digital cushion of the bovine claw with respect to age and location--a preliminary report

The pads of the bovine digital cushion, which serves as a shock absorber, have specific anatomical structures to cope with the substantial forces acting within the claw. To gain more information on the lipid composition and content of the pads, horn shoes from 12 slaughtered heifers and cows were removed and different samples of the pads excised with a scalpel. Pad lipids were extracted and the fatty acid composition determined by gas chromatography. Fat from perirenal and subcutaneous adipose tissues served as a comparison. Overall, this fat contained a higher quantity of extracted lipids than that of the claw pads and did not differ between heifers and cows. In contrast, lipid content in the pads was significantly higher in the cows than in the heifers. In both groups, the lipid content of the middle and abaxial pads, which are situated directly under the distal phalanx, was lower than in the pads of the other locations. The lipids in all pads contained >77% monounsaturated fatty acids (MUFA), differing sharply from the adipose tissue with values <51%. Among the polyunsaturated fatty acids (PUFA) a significantly higher proportion of arachidonic acid (AA) was found in the heifer pads than in those of the cows, whereas the proportion of AA was similar in the adipose tissue of all animals. The proportion of AA in the pad lipids also varied between the defined locations with the highest proportion found in locations that showed the lowest lipid content and was related to the age of the animal.

Psychosocial outcome in cardiovascular rehabilitation of peripheral artery disease and coronary artery disease patients

We investigated patients with a primary diagnosis of peripheral artery disease (n = 69) and coronary heart disease (CAD; n = 520) at baseline and on changes in psychosocial risk factors (depression, anxiety, quality of life, negative and positive affect) during a cardiovascular rehabilitation program. Patients completed psychosocial questionnaires at the beginning and at discharge of a 12-week rehabilitation program. Depression and anxiety were measured with the Hospital Anxiety and Depression Scale (HADS), positive and negative affect with the Global Mood Scale, and health-related quality of life with the SF-36 Health Survey. Patients with PAD showed improvements in anxiety (p < 0.001), negative affect (p < 0.001) and bodily pain (p < 0.001). Patients with CAD reported significant improvements in all measured dimensions (all p-values < 0.001).

Effect of photoactivated disinfection with a light-emitting diode on bacterial species and biofilms associated with periodontitis and peri-implantitis

BACKGROUND To determine the effect of photoactivated disinfection (PAD) using toluidine blue and a light-emitting diode (LED) in the red spectrum (wave length at 625-635 nm) on species associated with periodontitis and peri-implantitis and bacteria within a periodontopathic biofilm. METHODS Sixteen single microbial species including 2 Porphyromonas gingivalis and 2 Aggregatibacter actinomycetemcomitans and a multispecies mixture consisting of 12 species suspended in saline without and with 25% human serum were exposed to PAD. Moreover, single-species biofilms consisting of 2 P. gingivalis and 2 A. actinomycetemcomitans strains and a multi-species biofilm on 24-well-plates, grown on titanium discs and in artificial periodontal pockets were exposed to PAD with and without pretreatment with 0.25% hydrogen peroxide. Changes in the viability were determined by counting the colony forming units (cfu). RESULTS PAD reduced the cfu counts in saline by 1.42 log₁₀ after LED application for 30s and by 1.99 log₁₀ after LED application for 60s compared with negative controls (each p<0.001). Serum did not inhibit the efficacy of PAD. PAD reduced statistically significantly (p<0.05) the cfu counts of the P. gingivalis biofilms. The viability of the A. actinomycetemcomitans biofilms and the multi-species biofilms was statistically significantly decreased when PAD was applied after a pretreatment with 0.25% hydrogen peroxide. The biofilm formed in artificial pockets was more sensitive to PAD with and without pretreatment with hydrogen peroxide compared with those formed on titanium discs. CONCLUSIONS PAD using a LED was effective against periodontopathic bacterial species and reduced viability in biofilms but was not able to completely destroy complex biofilms. The use of PAD following pretreatment with hydrogen peroxide resulted in an additional increase in the antimicrobial activity which may represent a new alternative to treat periodontal and peri-implant infections thus warranting further testing in clinical studies.

Sex differences in the prevalence and clinical outcomes of subclinical peripheral artery disease in the Health, Aging, and Body Composition (Health ABC) study

The objective of the study was to determine if there are sex-based differences in the prevalence and clinical outcomes of subclinical peripheral artery disease (PAD). We evaluated the sex-specific associations of ankle-brachial index (ABI) with clinical cardiovascular disease outcomes in 2797 participants without prevalent clinical PAD and with a baseline ABI measurement in the Health, Aging, and Body Composition study. The mean age was 74 years, 40% were black, and 52% were women. Median follow-up was 9.37 years. Women had a similar prevalence of ABI < 0.9 (12% women versus 11% men; P = 0.44), but a higher prevalence of ABI 0.9-1.0 (15% versus 10%, respectively; P < 0.001). In a fully adjusted model, ABI < 0.9 was significantly associated with higher coronary heart disease (CHD) mortality, incident clinical PAD and incident myocardial infarction in both women and men. ABI < 0.9 was significantly associated with incident stroke only in women. ABI 0.9-1.0 was significantly associated with CHD death in both women (hazard ratio 4.84, 1.53-15.31) and men (3.49, 1.39-8.72). However, ABI 0.9-1.0 was significantly associated with incident clinical PAD (3.33, 1.44-7.70) and incident stroke (2.45, 1.38-4.35) only in women. Subclinical PAD was strongly associated with adverse CV events in both women and men, but women had a higher prevalence of subclinical PAD.

Quantification of Popliteal Artery Deformation During Leg Flexion in Subjects With Peripheral Artery Disease: A Pilot Study

Purpose: To quantify the in vivo deformations of the popliteal artery during leg flexion in subjects with clinically relevant peripheral artery disease (PAD). Methods: Five patients (4 men; mean age 69 years, range 56–79) with varying calcification levels of the popliteal artery undergoing endovascular revascularization underwent 3-dimensional (3D) rotational angiography. Image acquisition was performed with the leg straight and with a flexion of 70°/20° in the knee/hip joints. The arterial centerline and the corresponding branches in both positions were segmented to create 3D reconstructions of the arterial trees. Axial deformation, twisting, and curvatures were quantified. Furthermore, the relationships between the calcification levels and the deformations were investigated. Results: An average shortening of 5.9%±2.5% and twist rate of 3.8±2.2°/cm in the popliteal artery were observed. Maximal curvatures in the straight and flexed positions were 0.12±0.04 cm−1 and 0.24±0.09 cm−1, respectively. As the severity of calcification increased, the maximal curvature in the straight position increased from 0.08 to 0.17 cm−1, while an increase from 0.17 to 0.39 cm−1 was observed for the flexed position. Axial elongations and arterial twisting were not affected by the calcification levels. Conclusion: The popliteal artery of patients with symptomatic PAD is exposed to significant deformations during flexion of the knee joint. The severity of calcification directly affects curvature, but not arterial length or twisting angles. This pilot study also showed the ability of rotational angiography to quantify the 3D deformations of the popliteal artery in patients with various levels of calcification.

Investigating the Effects of Silencing EphA2 in Metastatic Breast Cancer Cells

EphA2, also known as ECK (epithelial cell kinase), is a transmembrane receptor tyrosine kinase that is commonly over-expressed in cancers such as those of the prostate, colon, lung, and breast. For breast cancers, EphA2 overexpression is most prominent in the ER-negative subtype, and is associated with a higher rate of lung metastasis. Studies conducted to demonstrate the role of EphA2 in a non-cancerous environment have shown that it is very important in developmental processes, but not in normal adult tissues. These results make EphA2 a prospective therapeutic target since new therapies are needed for the more aggressive ER-negative breast cancers. A panel of breast cancer cell lines was screened for expression of EphA2 by immunoblotting. Several of the overexpressing cell lines, including BT549, MDA-MB-231, and HCC 1954 were selected for experiments utilizing siRNA for transient knockdown and shRNA for stable knockdown. Targeted knockdown of EphA2 was measured using RT-PCR and immunoblotting techniques. Here, the functions of EphA2 in the process of metastasis have been elucidated using in vitro assays that indicate cancer cell metastatic potential and in vivo studies that reveal the effect of EphA2 on mammary fat pad tumor growth, vessel formation, and the effect of using EphA2-targeting siRNA on pre-established mammary fat pad tumors. A decrease in EphA2 expression both in vitro and in vivo correlated with reduced migration and experimental metastasis of breast cancer cells. Current work is being done to investigate the mechanism behind EphA2’s participation in some of these processes. These studies are important because they have contributed to understanding the role that EphA2 plays in the progression of breast cancers to a metastatic state.

Prime-boost vaccination with plasmid and adenovirus gene vaccines control HER2/neu+ metastatic breast cancer in mice.

INTRODUCTION: Once metastasis has occurred, the possibility of completely curing breast cancer is unlikely, particularly for the 30 to 40% of cancers overexpressing the gene for HER2/neu. A vaccine targeting p185, the protein product of the HER2/neu gene, could have therapeutic application by controlling the growth and metastasis of highly aggressive HER2/neu+ cells. The purpose of this study was to determine the effectiveness of two gene vaccines targeting HER2/neu in preventive and therapeutic tumor models. METHODS: The mouse breast cancer cell line A2L2, which expresses the gene for rat HER2/neu and hence p185, was injected into the mammary fat pad of mice as a model of solid tumor growth or was injected intravenously as a model of lung metastasis. SINCP-neu, a plasmid containing Sindbis virus genes and the gene for rat HER2/neu, and Adeno-neu, an E1,E2a-deleted adenovirus also containing the gene for rat HER2/neu, were tested as preventive and therapeutic vaccines. RESULTS: Vaccination with SINCP-neu or Adeno-neu before tumor challenge with A2L2 cells significantly inhibited the growth of the cells injected into the mammary fat or intravenously. Vaccination 2 days after tumor challenge with either vaccine was ineffective in both tumor models. However, therapeutic vaccination in a prime-boost protocol with SINCP-neu followed by Adeno-neu significantly prolonged the overall survival rate of mice injected intravenously with the tumor cells. Naive mice vaccinated using the same prime-boost protocol demonstrated a strong serum immunoglobulin G response and p185-specific cellular immunity, as shown by the results of ELISPOT (enzyme-linked immunospot) analysis for IFNgamma. CONCLUSION: We report herein that vaccination of mice with a plasmid gene vaccine and an adenovirus gene vaccine, each containing the gene for HER2/neu, prevented growth of a HER2/neu-expressing breast cancer cell line injected into the mammary fat pad or intravenously. Sequential administration of the vaccines in a prime-boost protocol was therapeutically effective when tumor cells were injected intravenously before the vaccination. The vaccines induced high levels of both cellular and humoral immunity as determined by in vitro assessment. These findings indicate that clinical evaluation of these vaccines, particularly when used sequentially in a prime-boost protocol, is justified.

The FReedom from Ischemic Events-New Dimensions for Survival (FRIENDS) registry: design of a prospective cohort study of patients with advanced peripheral artery disease.

BACKGROUND Advanced lower extremity peripheral artery disease (PAD), whether presenting as acute limb ischemia (ALI) or chronic critical limb ischemia (CLI), is associated with high rates of cardiovascular ischemic events, amputation, and death. Past research has focused on strategies of revascularization, but few data are available that prospectively evaluate the impact of key process of care factors (spanning pre-admission, acute hospitalization, and post-discharge) that might contribute to improving short and long-term health outcomes. METHODS/DESIGN The FRIENDS registry is designed to prospectively evaluate a range of patient and health system care delivery factors that might serve as future targets for efforts to improve limb and systemic outcomes for patients with ALI or CLI. This hypothesis-driven registry was designed to evaluate the contributions of: (i) pre-hospital limb ischemia symptom duration, (ii) use of leg revascularization strategies, and (iii) use of risk-reduction pharmacotherapies, as pre-specified factors that may affect amputation-free survival. Sequential patients would be included at an index "vascular specialist-defined" ALI or CLI episode, and patients excluded only for non-vascular etiologies of limb threat. Data including baseline demographics, functional status, co-morbidities, pre-hospital time segments, and use of medical therapies; hospital-based use of revascularization strategies, time segments, and pharmacotherapies; and rates of systemic ischemic events (e.g., myocardial infarction, stroke, hospitalization, and death) and limb ischemic events (e.g., hospitalization for revascularization or amputation) will be recorded during a minimum of one year follow-up. DISCUSSION The FRIENDS registry is designed to evaluate the potential impact of key factors that may contribute to adverse outcomes for patients with ALI or CLI. Definition of new "health system-based" therapeutic targets could then become the focus of future interventional clinical trials for individuals with advanced PAD.

Restenosis after infrapopliteal angioplasty - clinical importance, study update and further directions.

Patients with critical limb ischemia (CLI) represent the most severe form of peripheral arterial disease (PAD) and exhibit high mortality rates. Frequently, PAD in CLI patients involves the infrapopliteal arterial segment challenging endovascular revascularization strategies. Restenosis remains the major drawback of tibial angioplasty encountered in more than two thirds of CLI patients undergoing tibial revascularization. In contrast to earlier observations, tibial patency was recently shown to be essential to attain an optimal clinical outcome in CLI patients subsequent to tibial angioplasty. The exact pathopyhsiological mechanisms of tibial restenosis remains unclear. To date, most of our knowledge on tibial restenosis and its pathophysiology is derived from coronary arteries, based on the similarity of coronary arteries to tibial artery morphology. Nervertheless, multiple antirestenosis concepts are investigated within clinical trials to reduce tibial restenosis.Purpose of the present manuscript is to provide a current update on the pathophysiology of tibial restenosis and potential antirestenosis strategies.

Statin therapy and long-term adverse limb outcomes in patients with peripheral artery disease: insights from the REACH registry

AIMS Due to a high burden of systemic cardiovascular events, current guidelines recommend the use of statins in all patients with peripheral artery disease (PAD). We sought to study the impact of statin use on limb prognosis in patients with symptomatic PAD enrolled in the international REACH registry. METHODS Statin use was assessed at study enrolment, as well as a time-varying covariate. Rates of the primary adverse limb outcome (worsening claudication/new episode of critical limb ischaemia, new percutaneous/surgical revascularization, or amputation) at 4 years and the composite of cardiovascular death/myocardial infarction/stroke were compared among statin users vs. non-users. RESULTS A total of 5861 patients with symptomatic PAD were included. Statin use at baseline was 62.2%. Patients who were on statins had a significantly lower risk of the primary adverse limb outcome at 4 years when compared with those who were not taking statins [22.0 vs. 26.2%; hazard ratio (HR), 0.82; 95% confidence interval (CI), 0.72-0.92; P = 0.0013]. Results were similar when statin use was considered as a time-dependent variable (P = 0.018) and on propensity analysis (P < 0.0001). The composite of cardiovascular death/myocardial infarction/stroke was similarly reduced (HR, 0.83; 95% CI, 0.73-0.96; P = 0.01). CONCLUSION Among patients with PAD in the REACH registry, statin use was associated with an ∼18% lower rate of adverse limb outcomes, including worsening symptoms, peripheral revascularization, and ischaemic amputations. These findings suggest that statin therapy not only reduces the risk of adverse cardiovascular events, but also favourably affects limb prognosis in patients with PAD.

In vitro activity of photoactivated disinfection using a diode laser in infected root canals

OBJECTIVE To investigate the lethal activity of photoactivated disinfection (PAD) on Enterococcus faecalis (ATCC 29212) and mixed populations of aerobic or anaerobic bacteria in infected root canals using a diode laser after the application of a photosensitizer (PS). MATERIALS AND METHODS First, the bactericidal activity of a low power diode laser (200 mW) against E. faecalis ATCC 29212 pre-treated with a PS (toluidine blue) for 2 min were examined after different irradiation times (30 s, 60 s and 90 s). The bactericidal activity in the presence of human serum or human serum albumin (HSA) was also examined. Second, root canals were infected with E. faecalis or with mixed aerobic or anaerobic microbial populations for 3 days and then irrigated with 1.5% sodium hypochlorite and exposed to PAD for 60 s. RESULTS Photosensitization followed by laser irradiation for 60 s was sufficient to kill E. faecalis. Bacteria suspended in human serum (25% v/v) were totally eradicated after 30 s of irradiation. The addition of HSA (25 mg/ml or 50 mg/ml) to bacterial suspensions increased the antimicrobial efficacy of PAD after an irradiation time of 30 s, but no longer. The bactericidal effect of sodium hypochlorite was only enhanced by PAD during the early stages of treatment. PAD did not enhance the activity of sodium hypochlorite against a mixture of anaerobic bacteria. CONCLUSIONS The bactericidal activity of PAD appears to be enhanced by serum proteins in vitro, but is limited to bacteria present within the root canal.

The impact of prolonged lower limb ischemia on amputation, mortality, and functional status: the FRIENDS registry.

BACKGROUND Peripheral artery disease (PAD) is a major cause of cardiovascular ischemic events and amputation. Knowledge gaps exist in defining and measuring key factors that predict these events. The objective of this study was to assess whether duration of limb ischemia would serve as a major predictor of limb and patient survival. METHODS The FReedom from Ischemic Events: New Dimensions for Survival (FRIENDS) registry enrolled consecutive patients with limb-threatening peripheral artery disease at a single tertiary care hospital. Demographic information, key clinical care time segments, functional status and use of revascularization, and pharmacotherapy data were collected at baseline, and vascular ischemic events, cardiovascular mortality, and all-cause mortality were recorded at 30 days and 1 year. RESULTS A total of 200 patients with median (interquartile range) age of 76 years (65-84 years) were enrolled in the registry. Median duration of limb ischemia was 0.75 days for acute limb ischemia (ALI) and 61 days for chronic critical limb ischemia (CLI). Duration of limb ischemia of <12, 12 to 24, and >24 hours in patients with ALI was associated with much higher rates of first amputation (P = .0002) and worse amputation-free survival (P = .037). No such associations were observed in patients with CLI. CONCLUSIONS For individuals with ischemic symptoms <14 days, prolonged limb ischemia is associated with higher 30-day and 1-year amputation, systemic ischemic event rates, and worse amputation-free survival. No such associations are evident for individuals with chronic CLI. These data imply that prompt diagnosis and revascularization might improve outcomes for patients with ALI.

Systemic inflammation is higher in peripheral artery disease than in stable coronary artery disease.

OBJECTIVE The knowledge on the level of systemic inflammation in peripheral artery disease (PAD) is less well established than that in coronary artery disease (CAD). Systemic inflammation frequently coincides with atherosclerosis, but also with various traits of the metabolic syndrome (MetS). The individual contribution of CAD, PAD, and the MetS to inflammation is not known. METHODS We enrolled a total of 1396 patients, 460 patients with PAD Fontaine stages IIa-IV verified by duplex ultrasound (PAD group) and 936 patients free of limb claudication undergoing coronary angiography, of whom 507 had significant CAD with coronary stenoses ≥50% (CAD group), and 429 did not have significant CAD at angiography (control group). RESULTS C-reactive protein (CRP) was significantly higher in the PAD than in the CAD or in the control group (0.86 ± 1.85 mg/dl versus 0.44 ± 0.87 mg/dl and 0.39 ± 0.52 mg/dl, respectively, p < 0.001 for both comparisons). These significant differences were confirmed when patients with and subjects without the MetS were analyzed separately. In particular, within the PAD group, CRP was significantly higher in patients with the MetS than in subjects without the MetS (1.04 ± 2.01 vs. 0.67 ± 1.64 mg/dl; p = 0.001) and both, the presence of PAD and the MetS proved to be independently associated with CRP in analysis of covariance (F = 31.84; p < 0.001 and F = 10.52; p = 0.001, respectively). CONCLUSION Inflammatory activity in PAD patients is higher than in CAD patients and is particularly high in PAD patients affected by the MetS. Low grade systemic inflammation is independently associated with both the MetS and PAD.

Radical cystectomy and ileal orthotopic bladder substitution after radical retropubic prostatectomy: functional and oncological results

Men with good functional results following radical retropubic prostatectomy (RRP) and requiring radical cystectomy (RC) for subsequent bladder carcinoma seldom receive orthotopic bladder substitution. Four patients aged 62-72 years (median 67 years), who had undergone RRP for prostate cancer of stage pT2bN0M0 Gleason score 6 (n = 1), pT2cN0M0 Gleason score 5 and 6 (n = 2) and pT3bN0M0 Gleason score 7 (n = 1) 27 to 104 months before, developed urothelial bladder carcinoma treated with RC and ileal orthotopic bladder substitution. After radical prostatectomy three were continent and one had grade I stress incontinence, and three achieved intercourse with intracavernous alprostadil injections. Follow-up after RC ranged between 27 and 42 months (median 29 months). At the 24-month follow-up visit after RC daily urinary continence was total (0 pad) in one patient, two used one pad for mild leakage, and one was incontinent following endoscopic incision of anastomotic stricture. One patient died of progression of bladder carcinoma, while the other three are alive without evidence of disease. The three surviving patients continued to have sexual intercourse with intracavernous alprostadil injections. Men with previous RRP have a reasonable chance of maintaining a satisfactory functional outcome following RC and ileal orthotopic bladder substitution.
