Health empowerment scripts : simplifying social/green prescriptions
Social prescriptions are one term commonly used to describe non-pharmaceutical approaches to healthcare and are gaining popularity in the community, with evidence highlighting psychological benefits of reduced anxiety, depression and improved mood and physiological benefits of reduced risk of cardiovascular disease and reduced hypertension. The relationship between human health benefits and planetary health benefits is also noted. There are, however, numerous barriers, such as duration and frequencies to participate in activities, access, suitability, volition and a range of unpredictable variables (such as inclement weather, shifting interests and relocating home amongst others) impeding a comprehensive approach to their use on a wider scale. From a multidisciplinary perspective, this commentary incorporates a salutogenic and nature-based approach to health, we also provide a range of recommendations that can be undertaken at the patient level to assist in shifting the acknowledged systemic barriers currently occurring. These include using simple language to explain the purpose of health empowerment scripts, ensuing personal commitment to a minimum timeframe, enabling ease of access, co-designing a script program, providing ongoing motivational support and incorporating mindfulness to counter unexpected disruptions.

Non-typeable Haemophilus influenzaeâMoraxella catarrhalis vaccine for the prevention of exacerbations in chronic obstructive pulmonary disease: a multicentre, randomised, placebo-controlled, observer-blinded, proof-of-concept, phase 2b trial
International audienceBackgroundAcute exacerbations of chronic obstructive pulmonary disease (AECOPD) are associated with changes in the sputum microbiome, including an increased prevalence of pathogenic bacteria. Vaccination against the most frequent bacteria identified in AECOPD might reduce exacerbation frequency. We assessed the efficacy, safety, and immunogenicity of a candidate vaccine containing surface proteins from non-typeable Haemophilus influenzae (NTHi) and Moraxella catarrhalis (Mcat) in patients with COPD.MethodsThis multicentre, randomised, observer-blinded, placebo-controlled, proof-of-concept, phase 2b trial recruited patients with stable COPD, moderate-to-very severe airflow limitation (Global Initiative for Chronic Obstructive Lung Disease [GOLD] stage 2, 3, or 4), at 67 clinical sites in Belgium, Canada, France, Germany, Italy, Spain, UK, and USA. Eligible patients were aged 40â80 years and had a history of at least one moderate or severe exacerbation in the previous year. Patients were allocated (1:1) using a minimisation algorithm to receive two intramuscular injections of NTHiâMcat vaccine or placebo 60 days apart, in addition to standard care. The allocation algorithm considered age category, number of previous exacerbations, COPD severity at study entry, and country as minimisation factors, to guarantee treatment balance within each factor. Vaccine recipients and those responsible for evaluating study endpoints were masked to group allocation. In the analysis of efficacy, the primary outcome was the rate of any moderate or severe AECOPD occurring within a 1-year period, starting 1 month after the second dose in patients who received two vaccine doses (modified total vaccinated cohort). Safety was assessed in the total vaccinated cohort. The trial is registered with ClinicalTrials.gov, number NCT03281876, and is complete.FindingsBetween Nov 27, 2017, and Nov 30, 2018, 606 adults were enrolled and included in the total vaccinated cohort (304 in the NTHiâMcat vaccine group, 302 in the placebo group); 571 received two doses and were included in the primary efficacy analysis (279 in the NTHiâMcat vaccine group, 292 in the placebo group). 23 participants dropped-out in the NTHiâMcat vaccine group and 39 in the placebo group; this included 4 patients in the NTHiâMcat vaccine group and 15 in the placebo group who withdrew from the study because of an adverse event. The primary analysis included 340 exacerbations (in follow-up time 102â123 days) in the NTHiâMcat vaccine group and 333 (in 104â443 days) in the placebo group, with a yearly rate of moderate or severe AECOPD of 1·22 in the NTHiâMcat vaccine group and 1·17 in the placebo group, with vaccine efficacy in reducing the yearly rate of moderate or severe AECOPD estimated to be zero (vaccine efficacy point estimate 2·26% [87% CI â18·27 to 11·58]; p=0·82). Solicited local adverse events were more frequent in the NTHiâMcat vaccine group (216 [72%] of 301 patients) than with placebo (34 [11%] of 299 patients), and the frequency of solicited general adverse events was similar between groups (239 [79%] of 301 vs 235 [79%] of 299 patients). There was one death in the NTHiâMcat vaccine group (acute respiratory failure, not related to vaccination) and ten in the placebo group (seven due in part to COPD or respiratory failure). There were 158 serious adverse events (89 [29%] of 304 patients) in the NTHiâMcat vaccine group, not related to vaccination, and 214 (99 [33%] of 302 patients) in the placebo group.InterpretationNTHiâMcat vaccine administered to patients with COPD did not show efficacy in reducing the yearly rate of moderate or severe exacerbations. No safety concerns were identified

Natural polysaccharides for growth factors delivery
Natural polysaccharides have been extensively utilized in nutrition and pharmaceutical applications for several decades. A significant number of research has been performed on polysaccharides as a drug delivery system with aim to restore or repair defective tissues. Natural polysaccharides (chitosan, agarose, alginate, carrageenan, fucoidan, cellulose, hyaluronic acid, and ulvan) are proven to be used as drug delivery systems. In this chapter, we discuss the function of natural polysaccharides and their applications in growth factor delivery such as BMP-2, VEGF, PRP, FGF, etc. From the scientific results, it has been concluded that natural polysaccharides significantly hold the growth factors and release it in a sustainable manner enhancing tissue growth. In addition to this, most of the natural polysaccharides are biocompatible, biodegradable, and nontoxic to cells. Natural polysaccharides also act as extracellular matrix for regeneration of skin and bone tissues. Overall, proper mixture of natural polysaccharides with growth factors provides several advantages in biomedical applications
