RESUMEN

Illicit drug dependence is one of the most stigmatised health conditions worldwide and the harmful impacts of stigma for people who use drugs are well documented. The use of stigmatising language about drugs in traditional media is also well documented. The increasing use of digital media platforms has revolutionised the way we communicate, and extended the reach of our messages. However, there are issues specific to the ways in which these platforms operate that have the potential to increase drug-related stigma. This paper outlines the importance of language, narrative, and imagery in reducing this stigma. It discusses the challenges digital media platforms present to achieving this goal, including the use of engagement strategies that trigger fear and increase stigma, the potential for amplifying stigmatising messages by using algorithms, and the potential for dissemination of misinformation. Key strategies to frame conversations about drug use are presented including 1) appeal to values of fairness and equity rather than scaring people; 2) avoid correcting misinformation as it strengthens unhelpful stigmatising frames of drug use; and 3) create a new narrative, focusing on the diversity of experiences of people who use drugs. Internationally we are at a critical juncture with respect to drug policy reform, and efforts to reduce drug-related stigma are central to building support for these reforms. The extensive reach of digital media platforms represents an important opportunity to communicate about illicit drug use. The challenge is to do so in a way that minimises stigma. If we are to achieve change, a narrative that puts values, people, health care and equity at the centre of the conversation is critical.

RESUMEN

Air pollutants of PM2.5 can alter the composition of gut microbiota and lead to inflammation in the lung and gastrointestinal tract. The aim of this study was to evaluate the protective effect of a novel herbal extract blend, FC, composed of Lonicera japonica extract, Momordica grosvenori extract, and broccoli seed extract, on PM2.5-induced inflammation in the respiratory and intestinal tract. A549 cells and THP-1 cells, as well as C57BL/6 mice, were stimulated with PM2.5 to establish in vitro and in vivo exposure models. The models were treated with or without FC. The expression of inflammatory cytokines and tight junction proteins were studied. Proteomic analysis was performed to elucidate mechanisms. Mouse feces were collected for gut microbiota analysis. FC was shown to modulate the upregulation of pro-inflammatory cytokines mRNA expression in A549 and THP-1 cells and downregulated tight junction proteins mRNA expression in A549 cells due to PM2.5 stimulation. In animal models, the decreased expression of the anti-inflammatory factor il-10, tight junction protein ZO-1, and the elevated expression of COX-2 induced by PM2.5 were improved by FC intervention, which may be associated with zo-1 and cox-2 signaling pathways. In addition, FC was shown to improve the gut microbiota by increasing the abundance of beneficial bacteria.

RESUMEN

Consumption of high fat diets (HFD) and the associated metabolic endotoxemia can initiate liver inflammation and lipid deposition that with time can progress to non-alcoholic fatty liver disease (NAFLD). We previously observed that 14 weeks supplementation with the anthocyanidins cyanidin and delphinidin mitigated HFD-induced metabolic endotoxemia and liver insulin resistance, steatosis, inflammation and oxidative stress. This work investigated if a 4-week supplementation of mice with a cyanidin- and delphinidin-rich extract (CDRE) could mitigate or reverse HFD (60% calories from lard fat)-induced liver steatosis and inflammation. After a first 4-weeks period on the HFD, mice showed increased endotoxemia and activation of liver proinflammatory signaling cascades. Supplementation with CDRE between weeks 4 and 8 did not mitigate liver steatosis or the altered lipid and glucose plasma levels. However, CDRE supplementation reverted HFD-induced metabolic endotoxemia, in parallel with the mitigation of the overexpression of hepatic TLR2 and TLR4, and of the activation of: (i) NF-κB, (ii) AP-1 and upstream mitogen-activated kinases p38 and ERK1/2, and (iii) HIF-1. Thus, even a short-term consumption of cyanidin and delphinidin could help mitigate the adverse consequences, i.e. metabolic endotoxemia and associated liver inflammation, triggered by the regular consumption of diets rich in fat.

RESUMEN

Antioxidants and related compounds are anti-inflammatory and exhibit great potential in promoting human health. They are also often considered to be important elements in the process of neurodegeneration. Here we describe a antioxidant blend of Curcumin and Broccoli Seed Extract (BSE). Flies treated with the blend exhibit extended lifespan. RNA-seq analysis of samples from adult fly brains reveals a wide array of new genes with differential expression upon treatment with the blend. Interestingly, abolishing expression of some of the identified genes in dopaminergic (DA) neurons does not affect DA neuron number. Taken together, our findings reveal an antioxidant blend that promotes fly longevity and exhibits protective effect over neurodegeneration, demonstrating the importance of antioxidants in health and pathology.

RESUMEN

BACKGROUND: We previously described a novel micronutrient blend that behaves like a putative calorie restriction mimetic. The aim of this paper was to analyze the beneficial effects of our micronutrient blend in mice and C. elegans, and compare them with calorie restriction. METHODS: Whole transcriptomic analysis was performed in the brain cortex, skeletal muscle and heart in three groups of mice: old controls (30 months), old + calorie restriction and old + novel micronutrient blend. Longevity and vitality were tested in C. elegans. RESULTS: The micronutrient blend elicited transcriptomic changes in a manner similar to those in the calorie-restricted group and different from those in the control group. Subgroup analysis revealed that nuclear hormone receptor, proteasome complex and angiotensinogen genes, all of which are known to be directly related to aging, were the most affected. Furthermore, a functional analysis in C. elegans was used. We found that feeding C. elegans the micronutrient blend increased longevity as well as vitality. CONCLUSIONS: We describe a micronutrient supplement that causes similar changes (transcriptomic and promoting longevity and vitality) as a calorie restriction in mice and C. elegans, respectively, but further studies are required to confirm these effects in humans.

RESUMEN

BACKGROUND: Fecal microbiota transplantation (FMT) is highly effective for treating recurrent Clostridium difficile infection (CDI) in observational studies (>90%), but cure rates in clinical trials are lower. We performed a systematic review and meta-analysis to assess the efficacy of FMT for recurrent CDI in open-label studies and clinical trials . METHODS: A systematic search from January 1978 to March 2017 was performed to include clinical trials of FMT for CDI. We analyzed CDI resolution by calculating weighted pooled rates (WPRs). RESULTS: Thirteen trials were included, comprising 610 patients with CDI treated with single FMT. Overall, 439 patients had clinical cure (WPR, 76.1%; 95% confidence interval (CI), 66.4%-85.7%). There was significant heterogeneity among studies (I2 = 91.35%). Cure rates were lower in randomized trials (139/216 patients; WPR, 67.7%; 95% CI, 54.2%-81.3%) than in open-label studies (300/394 patients; WPR, 82.7%; 71.1%-94.3%) (P < .001). Subgroup analysis by FMT delivery modality showed lower cure rates with enema than colonoscopy (WPR, 66.3% vs 87.4%; P < .001) but no difference between colonoscopy and oral delivery (WPR, 87.4% vs 81.4%; P = .17). Lower rates were seen for studies including both recurrent and refractory CDI than for those including only recurrent CDI (WPR, 63.9% vs 79%; P < .001). CONCLUSIONS: FMT was associated with lower cure rates in randomized trials than in open-label and in observational studies. Colonoscopy and oral route are more effective than enema for stool delivery. The efficacy also seems to be higher for recurrent than for refractory CDI.

RESUMEN

Objective Effective health care for older people with complex health needs requires a diverse range of healthcare professionals working together. The Building Partnerships Framework of the New South Wales Agency for Clinical Innovation seeks to promote collaboration and integration among service providers. The aim of the present study was to inform implementation and evaluation of the Framework. Methods Data from the 45 and Up Study was linked with deaths and service data from hospitalisations and the Medicare Benefits Schedule (MBS). Participants with a hospitalisation for conditions representing 'geriatric syndrome' were allocated to a complex needs group; the remainder were allocated to a comparison group. Hospital admissions and MBS services use were modelled using log-linear Poisson regression. Results Multivariate analysis showed that the rate of hospitalisation in the 2 years following index admission for the complex needs group was 18% (95% confidence interval (CI) 1.12-1.24) greater than the comparison group and specialist physician attendance was 13% (95% CI 1.06 - 1.21) greater. The rate of general practitioner (GP) attendances was 2% (95% CI 0.97-1.07) greater in the complex needs group, but this was not statistically significant. Discussion The greater rates of hospitalisation and specialist service use, the absence of a similar finding for GP services and the prominence of the role of primary care in service integration literature, policy and strategy underscore the importance of careful planning, consultation and inclusiveness in the development and implementation of integrated care policy. What is known about the topic? Older people with complex health needs are significant consumers of primary and secondary health services and benefit from well-planned and coordinated care. What does this paper add? The findings presented here indicate that although hospitals and specialist physicians provide a significantly greater volume of services to people with complex health needs, GPs do not. Within the limitations of the present study, these findings can contribute to integrated care policy and strategy development and implementation. What are the implications for practitioners? Given the prominence of primary care in service integration literature, policy and strategy and the findings of the present study with regard to the relative level of GP involvement in the management of people with complex needs, careful policy implementation will be required to ensure GPs are able to contribute significantly to coordinated cooperation between health services.

RESUMEN

OBJECTIVES: To conduct an holistic economic evaluation of an Aboriginal community (Daruk)-controlled midwifery service in Western Sydney. METHODS: The study estimated direct programme costs and downstream savings to the health sector. Measures of antenatal attendance and perinatal outcome were compared between Aboriginal women with and without experiences of the antenatal programme through examination of antenatal clinic records and the New South Wales Midwives Data Collection for the period 1991-1996. Qualitative outcomes were analysed through interviews and focus groups. RESULTS: The net cost to the health sector was estimated to be $A1200 per client. Compared with Aboriginal women who received antenatal care in two conventional settings, there were no statistically significant differences in birthweight and perinatal survival. Gestational age at first visit was lower (17.2 vs 21.2 and 19.9 weeks), mean number of antenatal visits was higher (10.5 vs 5.5 and 9.5) and attendance for routine antenatal tests was better (94% vs 71% and 84%). Aboriginal clients were strongly positive about their experience of the Daruk service in terms of relationship and trust, accessibility, flexibility, provision of clear and appropriate information, continuity of care, empowerment and family-centred care. CONCLUSIONS: Net per client costs to the health service were modest. Quantitative evidence of improved antenatal outcomes was limited, but qualitative evaluation suggested the service was strongly valued. The outcomes examined in this study were broader than those used in conventional forms of economic evaluation and this enabled identification and analysis of more diverse sources of value from this programme.
