Summary of: Reeve JC et al. (2010) Does physiotherapy reduce the incidence of postoperative pulmonary complications following pulmonary resection via open thoracotomy? A preliminary randomised single-blind clinical trial. Eur J Cardiothorac Surg 37: 1158-1166. [Prepared by Kylie Hill, CAP Editor.]. Question: Does routine prophylactic targeted respiratory physiotherapy after elective pulmonary resection via open thoracotomy decrease the incidence of postoperative pulmonary complications and reduce length of hospital stay? Design: Randomised, controlled trial with concealed allocation in which those who collected outcome measures were blinded to group allocation. Setting: Hospital ward of a tertiary referral centre in Auckland, New Zealand. Participants: Adults scheduled for pulmonary resection via open thoracotomy. Exclusion criteria: (i) unable to understand written and spoken English, (ii) tumour invasion of the chest wall or brachial plexus, (iii) physiotherapy for a respiratory or shoulder problem within 2 weeks prior to admission, (iv) development of a postoperative pulmonary complication prior to randomisation on Day 1 postoperatively, or (v) intubation and mechanical ventilation ≥ 24 hours following surgery. Randomisation of 76 patients allocated 42 to the intervention group and 34 to the control group. Interventions: Both groups received usual medical and nursing care via a standardised clinical pathway, which included early and frequent position changes, sitting out of bed on the first postoperative day, early ambulation and frequent pain assessment. In addition, the intervention group received daily targeted respiratory physiotherapy, which comprised deep breathing and coughing exercises, assistance with ambulation, and progressive shoulder and thoracic cage exercises. Outcome measures: The primary outcome was incidence of postoperative pulmonary complications, defined using a standardised diagnostic tool. The secondary outcome was the length of hospital stay. Results: The primary and secondary outcomes were available for all enrolled patients. Neither the incidence of postoperative pulmonary complications [mean difference intervention-control 1.8% (95% CI -10.6 to 13.1%)] nor the hospital length of stay [intervention group median 6.0 days, control group median 6.0 days; p=0.87) differed significantly between groups. The overall incidence of postoperative pulmonary complications (3.9%) was lower than expected. Conclusion: In adults following open thoracotomy, the addition of targeted respiratory physiotherapy to a standardised clinical pathway that included early mobilisation did not reduce the incidence of postoperative pulmonary complications or change length of hospital stay. © 2011 Australian Physiotherapy Association.

DALLAS, Dec. 14, 2016 -- People who were in a stable marriage, and had never been divorced or widowed, had the best prospects of survival after having a stroke, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association. "Our research is the first to show that current and past marital experiences can have significant consequences for one's prognosis after a stroke," said Matthew E. Dupre, Ph.D., lead author and associate professor in the Department of Community and Family Medicine and the Clinical Research Institute at Duke University in Durham, North Carolina. "We hope that a greater recognition and understanding of these associations may enable healthcare providers to better identify and treat patients who may be at a potentially high risk of dying after suffering a stroke." Stroke, one of the leading causes of disability and death in the United States, affects nearly 800,000 adults each year. The risk factors associated with stroke -- high blood pressure, smoking and diabetes -- are well established, as are the factors related to recovering from stroke and improving survival, such as access to quality healthcare, reducing risk factors, and adhering to treatment plans. While studies have shown that social support, such as marriage, can have a significant impact on treatment of cardiovascular disease, the influence of marital status on stroke survival in adults remains poorly understood. To determine whether one's marital history plays a role in survival after suffering a stroke, Dupre and Renato D. Lopes, M.D., Ph.D., professor of medicine at Duke University Medical Center, used data from a nationally representative sample of older U.S. adults. The sample was collected as part of the Health and Retirement Study (HRS), an ongoing, prospective, study of older U.S. adults sponsored by the National Institute on Aging and the Institute for Social Research at the University of Michigan. The HRS includes marital histories from more than 50 years of prospective and retrospective interview data. For this study, the researchers selected respondents who reported a stroke from 1992 to 2010. The final sample included 2,351 adults aged 41 and older who were observed an average of 5.3 years over the 18-year study period. The researchers found: The risks of dying after a stroke were 71 percent greater for adults who never married than for adults who were continuously married. For patients who were divorced or widowed, the risks of dying after a stroke were 23 percent and 25 percent greater, respectively, than continuously married adults. In patients who were divorced or widowed more than once, the risks of dying after a stroke were 39 percent and 40 percent greater, respectively, than for continuously married adults. There was no evidence that the findings significantly differed between men and women or by race or ethnicity. Analysis of the data suggests that some of these risks are affected by differences in psychological and social factors, such as lack of children, limited social support and depressive symptoms that may have impeded recovery after a stroke. Multiple marital losses in one's lifetime were especially detrimental to recovery, regardless of one's current marital status. Unexpectedly, the researchers found that remarriage did not reduce the risks from past divorce or widowhood. A limitation of the study is that it only included adults who survived to hospital discharge and did not include those who died shortly after having a stroke. The results of this study have possible implications for public health awareness and practice, Dupre said. "More research is needed to know the full clinical implications of our findings. Greater knowledge about the risks associated with marital life and marital loss may be useful for personalizing care and improving outcomes for those who are recovering from a stroke."

DrugDev believes the only way to achieve real change in clinical research is through industry-wide collaboration, standardization and a beautiful technology experience. All three tenets were on display at the 2nd Annual DrugDev User Summit (hosted by Merck) which convened more than 100 clinical trial leaders from over 40 sponsor, CRO and site organizations to discuss innovation and the future of clinical research. “The DrugDev User Summit was a very engaging event,” said Dawn Furey, Executive Director/Head, Global Operations, at Merck. “To be honest, I didn’t think I would stay for the entire two days given my competing priorities, but I couldn’t step away. It was great.” Plenary and workshop sessions featured expert speakers from Merck, Janssen (last year’s host), Pfizer, Novartis, Eli Lilly, ICON, Boehringer-Ingelheim, InCyte, INC Research, Alkermes, BioMarin, Chesapeake IRB, Radiant Research, and Emerson Clinical Research Institute. Highlights from the agenda included: In addition to these engaging discussions, a key benefit of Summit was the sneak preview of upcoming DrugDev technology that will unify solutions to revolutionize how sponsors and CROs run clinical trials at a truly enterprise level. Featuring a single interface that spans functional areas and incorporates the DrugDev Golden Number, DrugDev customers will be the first to access dashboard reports, manage task lists, and track progress across hundreds of trials from one centralized and convenient resource. Attendees were buzzing about the exclusive solution, which will be officially unveiled in early 2017. Brenda Medina, Associate Director, Head of Analytics at BioMarin said, “I already use multiple DrugDev solutions so I find real value in a unified clinical suite that ties everything together. I’m excited to see how this tool will enable the industry to really bring drugs to market faster for our patients, as time is of the essence for us in the industry, and our patients are waiting." Attendees also participated in hands-on technology demos, provided valuable feedback to help guide future solutions, and enjoyed social networking events to build even stronger relationships with peers. “People who know me will be shocked at how little I have to say about the DrugDev User Summit,” said Ibraheem “Ibs” Mahmood, DrugDev President and CEO. “That’s because the beauty of the event wasn’t the agenda, which was wonderful, but rather bringing together all of these thought leaders into one room with one focused mission. That allowed me to take a step back and watch everyone share best practices, debate solutions to common challenges, and brainstorm ideas with each other. For over 100 clinical professionals to dedicate so much time to a vendor user meeting – which is bigger than some industry conferences – and then to be so engaged throughout it was a truly humbling experience. I consider it a strong testament to the impact DrugDev provides our customers, and I’ve never been more optimistic about the possibility of real change or more excited about the future of clinical research.” The DrugDev User Summit is complimentary for the sponsors, CROs and sites that use DrugDev technology on thousands of clinical trials worldwide.

Today, at American Heart Association’s Scientific Sessions 2016, digital health coaching startup Vida Health released findings from a peer-reviewed study of patients self-managing risk prevention after acute myocardial infarction (MI). The study, conducted with Duke Clinical Research Institute and AstraZeneca, found a statistically significant increase in pre- and post-intervention Patient Activation Measure (PAM) scores in ten cardiac patients using Vida’s coaching app on their smartphones. Prior research has shown that an increase in PAM scores of this magnitude is associated with increased medication adherence and reduced hospital utilization. “We are excited by these results, as they are consistent with what we see every day with cardiac patients who use Vida’s coaching app,” said Vida CEO and Co-founder Stephanie Tilenius. “To date, there has been little research on the acceptance and efficacy of using smartphones to deliver coaching and personalized support to post-acute myocardial infarction patients; this study demonstrates that patients can achieve improved outcomes with Vida’s coaching and content tailored specifically to their needs and delivered seamlessly through their mobile device.” A total of 21 participants (10 patients and 11 caregivers) completed the four-week intervention. The mean age of patients was 57 years, and 20% were women; caregivers had a mean age of 54 years and the majority (88%) were women. On average, participants engaged in one live video/phone consultation per week and opened the Vida app five times per week. Patients and caregivers texted an average of twenty-four and eight times per week, respectively. After the four-week coaching intervention in the post-MI cohort, patients were significantly more likely to agree with the statements “I have been able to maintain (keep up with) lifestyle changes, like eating right or exercising,” and “I know what treatments are available for my heart attack.” Eight out of ten patients (80%) said they would go to cardiac rehab after coaching, compared to the traditional 25% of post-MI patients who participate in cardiac rehab. Participants reported high levels of satisfaction with the program, with an average satisfaction rating of 8.3/10 across the patient and caregiver cohorts, and an average net promoter score of 61%, which is comparable to customer satisfaction levels for Apple’s iPhone. “Post-MI patients and caregivers embraced digital health coaching with high rates of interactivity, and patients reported increased PAM scores, which measure engagement in self-management and medication compliance,” said Dr. Tracy Wang of the Duke Clinical Research Institute. “We believe these early results demonstrate the significant value of mobile phone-based health coaching programs in augmenting rehabilitation in post-MI patients to reduce readmissions for cardiac patients.” In the U.S., about 735,000 people have a heart attack every year. Of these, 210,000 are second heart attacks. The average cost to traditional health insurers for the first 90 days following a heart attack is $38,501. The risk of a second heart event is reduced through lifestyle changes that include increased physical activity, stress management, improved diet, and medication adherence.

COPD: Journal of Chronic Obstructive Pulmonary Disease | Year: 2012

Background: This Phase III study evaluated the efficacy and safety of twice-daily aclidinium 200 μg and 400 μg versus placebo in the treatment of moderate-to-severe COPD. Methods: In this 12-week, double-blind, multicenter trial, patients were randomized (1:1:1) to inhaled twice-daily aclidinium 200 μg, aclidinium 400 μg, or placebo. Primary and secondary endpoints were changes from baseline in trough FEV1 and peak FEV1 at Week 12, respectively. Health status (St. George's Respiratory Questionnaire [SGRQ]), COPD symptoms (Transitional Dyspnea Index [TDI], night and early morning symptoms), and safety were also assessed. Results: A total of 561 patients (mean age, 64 ± 9 years) with a mean baseline FEV1 of 1.36 ± 0.54 L (47.2% of predicted value) were randomized. At Week 12, aclidinium 200 μg and 400 μg showed significant improvements from baseline in mean (95% CI) trough FEV1 compared with placebo by 86 (45, 127) mL and 124 (83,164) mL, respectively, and in peak FEV1 by 146 (101, 190) mL and 192 (148, 236) mL, respectively (p ≤ 0.0001 for all). Both aclidinium doses also provided significant improvements in SGRQ, TDI and almost all COPD symptom scores compared with placebo (p < 0.05 for all). Incidences of adverse events (AEs) were similar across treatment groups. The incidence of anticholinergic AEs was low and similar across groups (dry mouth: 0.5%1.6%; constipation: 0%-1.1%). Conclusions: Treatment of moderate-to-severe COPD patients with twice-daily aclidinium 200 μg and 400 μg was associated with significant improvements in bronchodilation, health status, and COPD symptoms. Both doses were well tolerated and had safety profiles similar to placebo. © 2012 Informa Healthcare USA, Inc.

Purpose: In castrate resistant prostate cancer cells we investigated the cytotoxic effect of simvastatin and the mechanism involved. Materials and Methods: After treating PC3 and DU-145 cells with simvastatin, cell viability and apoptosis were determined using tetrazolium salt based colorimetric assay and annexin-V-fluorescein isothiocyanate/propidium iodide double staining assay, respectively. To determine whether simvastatin affects the nuclear factor-κB pathway, we assessed IκBα and phosphorylated IκBα expression, and p65 and phosphorylated p65 subcellular localization by Western blot analysis. Also, changes in nuclear factor-κB transcriptional activity were assessed using a luciferase reporter assay. Results: After treating PC3 and DU-145 cells with 0, 20 or 40 μM simvastatin for 24, 48 or 72 hours, the proportion of viable cells decreased and the proportion of apoptotic cells increased in a dose and time dependent manner. Western blot analysis showed that simvastatin inhibited IκBα phosphorylation and degradation. It also demonstrated that simvastatin increased p65 protein levels in cytoplasmic fractions and decreased phosphorylated p65 protein levels in nuclear fractions but did not change p65 protein levels in cytoplasm. Luciferase reporter assay showed that simvastatin dose dependently reduced nuclear factor-κB activity. Reverse transcriptase-polymerase chain reaction and Western blot revealed that simvastatin inhibited nuclear factor-κB regulated cIAP-1 and 2, cFLIP-S and XIAP expression in dose and time dependent fashion. Conclusions: Simvastatin inhibited castrate resistant prostate cancer cell growth by inducing apoptosis. These effects were probably mediated by the inhibition of IκBα phosphorylation and nuclear translocation of p50/p65 dimer in the nuclear factor-κB pathway. © 2013 American Urological Association Education and Research, Inc.

Gastrointestinal adenocarcinoma (GIA) is a common malignant disease worldwide. Its tumorigenesis and progression is a multistage process with the involvement of a multifactorial etiology. Knowledge regarding altered expression of these genes during carcinogenesis may not only provide information about the molecular events during the initiation and progression of cancer, but may also result in the discovery of biological markers for the evaluation of cancer diagnosis and prognosis. In this review, we assessed molecular markers of pathogenesis, invasion, metastasis and prognosis, such as tumor suppressor and metastasis suppressor genes, and angiogenesis, cell adhesion, cell mobility, ER stress, mucin production, threonine protein kinase and REG family protein expression, by the establishment of tissue microarray (TMA) of GIA and immunohistochemistry (IHC) by intermittent microwave irradiation and in situ hybridization (ISH). Finally, we characterized the pathobiological features of Lauren's and WHO subtypes. It was found that the aberrant and cell-specific expression of these molecules is important in the malignant transformation of gastrointestinal epithelium and subsequent progression. These molecules also underlie the histogenic mechanisms of gastric carcinoma according to Lauren's and WHO classification. The combination of TMA, IHC and ISH may be widely applied to screen for molecular markers in GIA.

Journal of Psychiatric Practice | Year: 2011

This column, the third in a series on central nervous system (CNS) drug development, discusses advances during the first decade of the 21st century and directions the field may take in the next 10 years. By identifying many possible new drug targets, the human genome project has created the potential to develop novel central nervous system (CNS) drugs with new mechanisms of action. At the same time, this proliferation of possible new targets has complicated the drug development process, since research has not yet provided guidance as to which targets may be most fruitful. This and other factors (eg, increasing regulatory requirements) have increased the cost and complexity of the drug development process. In addition, as more is learned about the biology of psychiatric illnesses, syndromes may be subdivided into more specific entities that are better understood from a pathophysiological and pathoetiological perspective. This is likely to lead to development of more targeted treatments focused on underlying causes of illness as well as prevention. The development of drugs for Alzheimer's disease is discussed as a possible model for future CNS drug development. We are at the beginning of an era when it is likely that the way in which CNS drugs are developed will need to be rethought, which will call for flexibility and creativity on the part of both drug developers and clinical researchers.

President Barack Obama's choice for commissioner of the Food and Drug Administration won easy approval from a Senate panel Tuesday, but two senators - a Republican and Democratic presidential candidate Bernie Sanders - threatened to block the nominee. Sen. Lisa Murkowski said she will hold up a vote on the Senate floor until she has reassurances from the agency that it will write rules for labeling genetically modified salmon. The Alaska Republican has said the engineered salmon approved by the FDA last year could be harmful to her state's wild salmon industry. Califf is now the No. 2 official at the agency, which regulates consumer products from medications to seafood to e-cigarettes. He was a prominent cardiologist and medical researcher at Duke University for more than 30 years. Murkowski said she is angry that she didn't get more of a warning about the agency's approval of the modified fish, which she has long opposed. The FDA approved the salmon two days after Califf's November confirmation hearing. "If they are trying to get my support, they sure fumbled that ball," she said after the Senate panel approved the nomination on a voice vote. Sanders, I-Vt., also opposes Califf's nomination. The presidential contender did not attend the committee meeting, but his office said he would have voted no. Sanders has said the country needs an FDA commissioner who will stand up to the pharmaceutical industry and that Califf is "not that person." He said he is also considering a hold on the nomination. Some Democrats have raised concerns about Califf's ties to industry. In 2006, Califf founded the Duke University Clinical Research Institute, a contract research group that has conducted studies for virtually all of the world's largest drugmakers. Government disclosure forms show that Califf received more than $29,000 in consulting fees, travel, meals and other payments from drugmakers in 2014. Califf has already recused himself from dealing with certain companies to avoid conflicts of interest. "I think if you look at my record you'll find I've never been a proponent of lowering standards," Califf said during his nomination hearing. He said he declined to do many studies because drug companies wouldn't meet his criteria for data access. Califf's nomination does have the support of the Republican chairman of the Health, Education, Labor and Pensions Committee. Tennessee Sen. Lamar Alexander said Califf has been thoroughly vetted, and he is confident that Califf can lead the agency "fairly and impartially." As head of the FDA, Califf would inherit a raft of projects and potential challenges, including unfinished tobacco regulations and food safety and labeling reforms. Former FDA Commissioner Margaret Hamburg left the job early last year. The FDA's chief scientist, Dr. Stephen Ostroff, is serving as acting head of the agency.
