Students in the PSU Real Estate Development Workshop produce a development plan for 12 properties located on the Central Eastside Industrial District (CEID). These properties are owned by the Pelett Family. Their task was to produce an original development plan, including the development concept, the market analysis, the conceptual design, economic analysis, capital and operations budget, and management plan
Enhancing the reporting of implementation research
In the 10 years since the inception of Implementation Science, we have witnessed a continued rise in the number of submissions received, reflecting the continued global interest in methods to enhance the uptake of research findings into healthcare practice and policy. We receive over 750 submissions annually, and there is now a large gap between what is submitted and what gets published. In this editorial, we restate the journal scope and current boundaries. We also identify some specific reporting issues that if addressed will help enhance the scientific reporting quality and transparency of the manuscripts we receive. We hope that this editorial acts as a further guide to researchers seeking to publish their work in Implementation Science
Novel mutations in human and mouse SCN4A implicate AMPK in myotonia and periodic paralysis
Mutations in the skeletal muscle channel (SCN4A), encoding the Nav1.4 voltage-gated sodium channel, are causative of a variety of muscle channelopathies, including non-dystrophic myotonias and periodic paralysis. The effects of many of these mutations on channel function have been characterized both in vitro and in vivo. However, little is known about the consequences of SCN4A mutations downstream from their impact on the electrophysiology of the Nav1.4 channel. Here we report the discovery of a novel SCN4A mutation (c.1762A>G; p.I588V) in a patient with myotonia and periodic paralysis, located within the S1 segment of the second domain of the Nav1.4 channel. Using N-ethyl-N-nitrosourea mutagenesis, we generated and characterized a mouse model (named draggen), carrying the equivalent point mutation (c.1744A>G; p.I582V) to that found in the patient with periodic paralysis and myotonia. Draggen mice have myotonia and suffer from intermittent hind-limb immobility attacks. In-depth characterization of draggen mice uncovered novel systemic metabolic abnormalities in Scn4a mouse models and provided novel insights into disease mechanisms. We discovered metabolic alterations leading to lean mice, as well as abnormal AMP-activated protein kinase activation, which were associated with the immobility attacks and may provide a novel potential therapeutic target

Basic science232. Certolizumab pegol prevents pro-inflammatory alterations in endothelial cell function
Background: Cardiovascular disease is a major comorbidity of rheumatoid arthritis (RA) and a leading cause of death. Chronic systemic inflammation involving tumour necrosis factor alpha (TNF) could contribute to endothelial activation and atherogenesis. A number of anti-TNF therapies are in current use for the treatment of RA, including certolizumab pegol (CZP), (Cimzia ®; UCB, Belgium). Anti-TNF therapy has been associated with reduced clinical cardiovascular disease risk and ameliorated vascular function in RA patients. However, the specific effects of TNF inhibitors on endothelial cell function are largely unknown. Our aim was to investigate the mechanisms underpinning CZP effects on TNF-activated human endothelial cells. Methods: Human aortic endothelial cells (HAoECs) were cultured in vitro and exposed to a) TNF alone, b) TNF plus CZP, or c) neither agent. Microarray analysis was used to examine the transcriptional profile of cells treated for 6 hrs and quantitative polymerase chain reaction (qPCR) analysed gene expression at 1, 3, 6 and 24 hrs. NF-κB localization and IκB degradation were investigated using immunocytochemistry, high content analysis and western blotting. Flow cytometry was conducted to detect microparticle release from HAoECs. Results: Transcriptional profiling revealed that while TNF alone had strong effects on endothelial gene expression, TNF and CZP in combination produced a global gene expression pattern similar to untreated control. The two most highly up-regulated genes in response to TNF treatment were adhesion molecules E-selectin and VCAM-1 (q 0.2 compared to control; p > 0.05 compared to TNF alone). The NF-κB pathway was confirmed as a downstream target of TNF-induced HAoEC activation, via nuclear translocation of NF-κB and degradation of IκB, effects which were abolished by treatment with CZP. In addition, flow cytometry detected an increased production of endothelial microparticles in TNF-activated HAoECs, which was prevented by treatment with CZP. Conclusions: We have found at a cellular level that a clinically available TNF inhibitor, CZP reduces the expression of adhesion molecule expression, and prevents TNF-induced activation of the NF-κB pathway. Furthermore, CZP prevents the production of microparticles by activated endothelial cells. This could be central to the prevention of inflammatory environments underlying these conditions and measurement of microparticles has potential as a novel prognostic marker for future cardiovascular events in this patient group.

New Australian guidelines for the treatment of alcohol problems: an overview of recommendations
Summary of recommendations and levels of evidence
Chapter 2: Screening and assessment for unhealthy alcohol use
Screening
Screening for unhealthy alcohol use and appropriate interventions should be implemented in general practice (Level A), hospitals (Level B), emergency departments and community health and welfare settings (Level C).
Quantity–frequency measures can detect consumption that exceeds levels in the current Australian guidelines (Level B).
The Alcohol Use Disorders Identification Test (AUDIT) is the most effective screening tool and is recommended for use in primary care and hospital settings. For screening in the general community, the AUDIT-C is a suitable alternative (Level A).
Indirect biological markers should be used as an adjunct to screening (Level A), and direct measures of alcohol in breath and/or blood can be useful markers of recent use (Level B).
Assessment
Assessment should include evaluation of alcohol use and its effects, physical examination, clinical investigations and collateral history taking (Level C).
Assessment for alcohol-related physical problems, mental health problems and social support should be undertaken routinely (GPP).
Where there are concerns regarding the safety of the patient or others, specialist consultation is recommended (Level C).
Assessment should lead to a clear, mutually acceptable treatment plan which specifies interventions to meet the patient’s needs (Level D).
Sustained abstinence is the optimal outcome for most patients with alcohol dependence (Level C).
Chapter 3: Caring for and managing patients with alcohol problems: interventions, treatments, relapse prevention, aftercare, and long term follow-up
Brief interventions
Brief motivational interviewing interventions are more effective than no treatment for people who consume alcohol at risky levels (Level A).
Their effectiveness compared with standard care or alternative psychosocial interventions varies by treatment setting. They are most effective in primary care settings (Level A).
Psychosocial interventions
Cognitive behaviour therapy should be a first-line psychosocial intervention for alcohol dependence. Its clinical benefit is enhanced when it is combined with pharmacotherapy for alcohol dependence or an additional psychosocial intervention (eg, motivational interviewing) (Level A).
Motivational interviewing is effective in the short term and in patients with less severe alcohol dependence (Level A).
Residential rehabilitation may be of benefit to patients who have moderate-to-severe alcohol dependence and require a structured residential treatment setting (Level D).
Alcohol withdrawal management
Most cases of withdrawal can be managed in an ambulatory setting with appropriate support (Level B).
Tapering diazepam regimens (Level A) with daily staged supply from a pharmacy or clinic are recommended (GPP).
Pharmacotherapies for alcohol dependence
Acamprosate is recommended to help maintain abstinence from alcohol (Level A).
Naltrexone is recommended for prevention of relapse to heavy drinking (Level A).
Disulfiram is only recommended in close supervision settings where patients are motivated for abstinence (Level A).
Some evidence for off-label therapies baclofen and topiramate exists, but their side effect profiles are complex and neither should be a first-line medication (Level B).
Peer support programs
Peer-led support programs such as Alcoholics Anonymous and SMART Recovery are effective at maintaining abstinence or reductions in drinking (Level A).
Relapse prevention, aftercare and long-term follow-up
Return to problematic drinking is common and aftercare should focus on addressing factors that contribute to relapse (GPP).
A harm-minimisation approach should be considered for patients who are unable to reduce their drinking (GPP).
Chapter 4: Providing appropriate treatment and care to people with alcohol problems: a summary for key specific populations
Gender-specific issues
Screen women and men for domestic abuse (Level C).
Consider child protection assessments for caregivers with alcohol use disorder (GPP).
Explore contraceptive options with women of reproductive age who regularly consume alcohol (Level B).
Pregnant and breastfeeding women
Advise pregnant and breastfeeding women that there is no safe level of alcohol consumption (Level B).
Pregnant women who are alcohol dependent should be admitted to hospital for treatment in an appropriate maternity unit that has an addiction specialist (GPP).
Young people
Perform a comprehensive HEEADSSS assessment for young people with alcohol problems (Level B).
Treatment should focus on tangible benefits of reducing drinking through psychotherapy and engagement of family and peer networks (Level B).
Aboriginal and Torres Strait Islander peoples
Collaborate with Aboriginal or Torres Strait Islander health workers, organisations and communities, and seek guidance on patient engagement approaches (GPP).
Use validated screening tools and consider integrated mainstream and Aboriginal or Torres Strait Islander-specific approaches to care (Level B).
Culturally and linguistically diverse groups
Use an appropriate method, such as the “teach-back” technique, to assess the need for language and health literacy support (Level C).
Engage with culture-specific agencies as this can improve treatment access and success (Level C).
Sexually diverse and gender diverse populations
Be mindful that sexually diverse and gender diverse populations experience lower levels of satisfaction, connection and treatment completion (Level C).
Seek to incorporate LGBTQ-specific treatment and agencies (Level C).
Older people
All new patients aged over 50 years should be screened for harmful alcohol use (Level D).
Consider alcohol as a possible cause for older patients presenting with unexplained physical or psychological symptoms (Level D).
Consider shorter acting benzodiazepines for withdrawal management (Level D).
Cognitive impairment
Cognitive impairment may impair engagement with treatment (Level A).
Perform cognitive screening for patients who have alcohol problems and refer them for neuropsychological assessment if significant impairment is suspected (Level A).
Summary of key recommendations and levels of evidence
Chapter 5: Understanding and managing comorbidities for people with alcohol problems: polydrug use and dependence, co-occurring mental disorders, and physical comorbidities
Polydrug use and dependence
Active alcohol use disorder, including dependence, significantly increases the risk of overdose associated with the administration of opioid drugs. Specialist advice is recommended before treatment of people dependent on both alcohol and opioid drugs (GPP).
Older patients requiring management of alcohol withdrawal should have their use of pharmaceutical medications reviewed, given the prevalence of polypharmacy in this age group (GPP).
Smoking cessation can be undertaken in patients with alcohol dependence and/or polydrug use problems; some evidence suggests varenicline may help support reduction of both tobacco and alcohol consumption (Level C).
Co-occurring mental disorders
More intensive interventions are needed for people with comorbid conditions, as this population tends to have more severe problems and carries a worse prognosis than those with single pathology (GPP).
The Kessler Psychological Distress Scale (K10 or K6) is recommended for screening for comorbid mental disorders in people presenting for alcohol use disorders (Level A).
People with alcohol use disorder and comorbid mental disorders should be offered treatment for both disorders; care should be taken to coordinate intervention (Level C).
Physical comorbidities
Patients should be advised that alcohol use has no beneficial health effects. There is no clear risk-free threshold for alcohol intake. The safe dose for alcohol intake is dependent on many factors such as underlying liver disease, comorbidities, age and sex (Level A).
In patients with alcohol use disorder, early recognition of the risk for liver cirrhosis is critical. Patients with cirrhosis should abstain from alcohol and should be offered referral to a hepatologist for liver disease management and to an addiction physician for management of alcohol use disorder (Level A).
Alcohol abstinence reduces the risk of cancer and improves outcomes after a diagnosis of cancer (Level A)
