RESUMO

Phytoremediation has been explored as a cost-effective method to remediate soil Pb contamination. A greenhouse study was conducted to evaluate the efficacy of Vigna unguiculata, Brassica pekinensis, Gomphrena globose, and Helianthus annuus for removing and immobilizing Pb in soil collected from the Westside Lead Superfund site in Atlanta. Plants were cultivated in sampled soil with a Pb concentration of 515 ± 10 mg/kg for 60 days. Soils growing H. annuus were additionally treated with ethylenediaminetetraacetic acid (EDTA) (0.1 g/kg) or compost (20% soil blend) to assess their capabilities for enhancing phytoremediation. Mean post-phytoremediation Pb concentrations in the four plant species were 23.5, 25.7, 50.0, and 58.1 mg/kg dry weight (DW), respectively, and were substantially higher than 1.55 mg/kg DW in respective plant species grown in control soils with no Pb contamination. The highest Pb concentration, translocation factor, and biomass were found in V. unguiculate among four species without soil amendments. H. annuus treated with EDTA and compost resulted in a significant increase in the total Pb uptake and larger biomass compared to non-treated plants, respectively. Although this study found that V. unguiculata was the best candidate for Pb accumulation and immobilization among four species, soil remediation was limited to 54 mg/kg in a growing season. We find that it is critically important to perform phytostabilization in a secure manner, since Pb bioavailability of edible plant parts implies the potential risk associated with their unintentional consumption. Efficiently and effectively remediating Pb-contaminated soils in a low-cost manner needs to be further studied.

RESUMO

OBJECTIVE: Obesity was once considered a risk factor for knee osteoarthritis (OA) primarily for biomechanical reasons. Here we provide an additional perspective by discussing how obesity also increases OA risk by altering metabolism and inflammation. DESIGN: This narrative review is presented in four sections: 1) metabolic syndrome and OA, 2) metabolic biomarkers of OA, 3) evidence for dysregulated chondrocyte metabolism in OA, and 4) metabolic inflammation: joint tissue mediators and mechanisms. RESULTS: Metabolic syndrome and its components are strongly associated with OA. However, evidence for a causal relationship is context dependent, varying by joint, gender, diagnostic criteria, and demographics, with additional environmental and genetic interactions yet to be fully defined. Importantly, some aspects of the etiology of obesity-induced OA appear to be distinct between men and women, especially regarding the role of adipose tissue. Metabolomic analyses of serum and synovial fluid have identified potential diagnostic biomarkers of knee OA and prognostic biomarkers of disease progression. Connecting these biomarkers to cellular pathophysiology will require future in vivo studies of joint tissue metabolism. Such studies will help reveal when a metabolic process or a metabolite itself is a causal factor in disease progression. Current evidence points towards impaired chondrocyte metabolic homeostasis and metabolic-immune dysregulation as likely factors connecting obesity to the increased risk of OA. CONCLUSIONS: A deeper understanding of how obesity alters metabolic and inflammatory pathways in synovial joint tissues is expected to provide new therapeutic targets and an improved definition of "metabolic" and "obesity" OA phenotypes.

RESUMO

During the second quarter of 2018, Cortellis Competitive Intelligence registered 985 new deals (excluding mergers and acquisitions) with a total disclosed deal value of USD 19.5 billion as part of its ongoing coverage of licensing activity in the life sciences sector compared to 964 and USD 35.6 billion in the first quarter and 1,104 and USD 13.6 billion in the second quarter of 2017. Total deal value in the second quarter did not quite reach the peak of 2014 (paced by Novartis' USD 16 billion purchase of GlaxoSmithKline's oncology portfolio) but eclipsed the previous quarter primarily due to Allogene's USD 2.8 billion license for Cellectis' chimeric antigen receptor T-cell immunotherapy program for cancer.

RESUMO

This eagle's-eye overview of the drug industry in 2017 provides insight into some of last year's top stories, including the growing opioid crisis affecting the U.S. and other developed countries and the 2017-2018 influenza epidemic, with a spotlight on the need for a universal flu vaccine. As in previous years, we also review orphan drug development, new agency-supported programs such as PRIME and RMAT, pipeline attrition and drug pricing, as well as pharma/biotech mergers and acquisitions of note. Finally, we take a glimpse into the crystal ball to anticipate the new drugs that will be approved in 2018.

RESUMO

Background: Local initiatives to reduce alcohol harms are common. One UK approach, Community Alcohol Partnerships (CAPs), involves partnerships between the alcohol industry and local government, focussing on alcohol misuse and anti-social behaviour (ASB) among young people. This study aimed to assess the evidence of effectiveness of CAPs. Methods: We searched CAP websites and documents, and databases, and contacted CAPs to identify evaluations and summarize their findings. We appraised these against four methodological criteria: (i) reporting of pre-post data; (ii) use of comparison area(s); (iii) length of follow-up; and (iv) baseline comparability of comparison and intervention areas. Results: Out of 88 CAPs, we found three CAP evaluations which used controlled designs or comparison areas, and further data on 10 other CAPs. The most robust evaluations found little change in ASB, though few data were presented. While CAPs appear to affect public perceptions of ASB, this is not a measure of the effectiveness of CAPs. Conclusions: Despite industry claims, the few existing evaluations do not provide convincing evidence that CAPs are effective in reducing alcohol harms or ASB. Their main role may be as an alcohol industry corporate social responsibility measure which is intended to limit the reputational damage associated with alcohol-related ASB.

RESUMO

During the second quarter of 2017, Cortellis Competitive Intelligence added 967 new licensing deals (excluding mergers and acquisition deals) as part of its ongoing coverage of pharmaceutical licensing activity. This meant an 8% decrease on the previous quarter (1,050) and a 3% decrease from the same quarter in 2016 (993). This quarter also showed a significant decline in the number of deals worth more than USD 0.5 billion from the last quarter (7 vs. 17). This article will highlight a number of the most valuable and notable deals forged during the quarter, as well as a selection of deals from some of the most prolific deal makers in the life sciences. An update on milestone, options and terminated deals of significance will also be presented, along with an early outlook on the next quarter's pharmaceutical licensing activity.

RESUMO

Tighter national budgets and escalating drug prices continue to present challenges for pharmaceutical market access strategies and societal cost of care. As pharmaceutical companies and medical governmental advisory organizations enter tougher negotiations, hospital trusts and other dispensary firms face barriers to receiving the best medical treatment, and as a result patient access is limited. The 2016 HealthNetwork Communications' Pharma Pricing & Market Access Europe meeting brought together pharmaceutical, medical governmental advisory and stakeholders and market access/pricing consultants, to encourage discussions and negotiations into how to improve the drug pricing system and consequential market access strategies while achieving the respective reimbursement and affordability objectives.

RESUMO

Translating perceived market value for pharmaceutical products into a willingness to pay remains the key factor in ensuring market access and return on investment. How price is managed in the context of new market entrants or new approval settings can create complex challenges, and further complexity is added through diverse global reimbursement structures and the myriad of stakeholders involved at every step of value identification. SMi's 21st Annual Meeting on European Pricing and Reimbursement presented a program focused on the measures being taken by European healthcare systems as they seek to facilitate access to the latest treatments while delivering value for payers and patients. Supporting patient access to life-changing medicines is a challenge, and funders are responding in many different ways; however, while the pharma industry continues to focus its efforts on high cost drugs that treat diseases of the few, the disconnect will be not be resolved. The speakers and delegates at the annual meeting believe success is possible by focusing on value for patients, driven by provider experience, scale and learning. Instead of simply lowering costs, companies, providers and payers can more adequately contribute to the goals of funders as well as the treatment needs of patients.

RESUMO

A paradigm shift in the treatment of chronic lymphocytic leukemia (CLL) has taken place over the past decade, as therapies have progressed from providing palliative relief to inducing complete remission, eradicating minimal disease and improving survival. The development of Rituxan® (rituximab) and its use in immunochemotherapy regimens has transformed the treatment of CLL and is the current gold standard in physically fit individuals aged < 65 years. Despite this therapeutic development, Rituxan-based immunochemotherapy is limited in the two CLL groups that form the majority of CLL cases-the elderly and patients with comorbidities and high risk factors. Moreover, within 2 years of first- and second-line therapy, around 25% and 50% of patients relapse, respectively, and patients who experience remission for several years exhibit poor responses to subsequent therapies. Therefore, there still remains a significant unmet need in CLL. The rapid development of small-molecule agents targeting the B-cell receptor signaling pathway has been stimulated both by the association of this pathway with the initiation and progression of CLL as well as the high response rates and durable remissions reported in early-stage trials. Imbruvica (ibrutinib), an oral first-in-class Bruton's tyrosine kinase inhibitor, recently entered the market following accelerated approval in the relapsed/refractory setting, but long-term survival data are currently immature. New therapies face several significant challenges: to provide even greater response rates, particularly in the elderly and in patients with comorbidities and high risk factors, and to overcome resistance to current treatments. Currently, the only curative treatment for CLL, allogeneic hematopoietic stem cell transplantation, is not an option for the majority of CLL patients. The ultimate question is whether small-molecule therapeutics can achieve a cure for CLL. It is hoped that developments in identifying the cytogenetic and molecular changes associated with the prognosis and pathogenesis of CLL will enable the rapid development of next-generation targeted therapies.

RESUMO

OBJECTIVE: The study objective was to assess the effectiveness of a turmeric- and sandal wood oil-containing cream [Vicco(®) turmeric cream (VTC); Vicco Laboratories, Parel, India] on radiodermatitis in patients with head and neck cancer undergoing radiotherapy. METHODS: A total of 50 patients with head and neck cancer requiring >60 Gy of curative radiotherapy/chemoradiotherapy were enrolled in the study. The volunteers were randomly divided into two groups of 25 patients. Group 1 was assigned to a topical application of Johnson's(®) baby oil (Johnson & Johnson Ltd, Baddi, India) and Group 2 for VTC. Prophylactic application of the cream was initiated on Day 1 and continued every day until 2 weeks after the end of treatment. Both agents were symmetrically applied within the irradiated field five times a day, and the acute skin reactions were assessed twice weekly in accordance with the Radiation Therapy Oncology Group scores by an investigator who was unaware of the details. RESULTS: The incidence of radiodermatitis increased with the exposure to radiation and was the highest in both groups at Week 7. However, a significant reduction in grades of dermatitis were seen in cohorts applying VTC at all time points, including 2 weeks post radiotherapy (p < 0.015 to p < 0.001). The occurrence of Grade 3 dermatitis was lower in the cohorts using VTC and was statistically significant (p < 0.01). Additionally, follow-up observations 2 weeks after the completion of radiotherapy also showed a reduced degree of radiodermatitis in cohorts applying VTC, which was significant (p = 0.015). CONCLUSION: VTC is shown to be effective in preventing radiodermatitis and needs to be validated in larger double-blind trials. ADVANCES IN KNOWLEDGE: For the first time, this study shows that the turmeric- and sandal oil-based cream was effective in preventing radiation-induced dermatitis.
