Implementation, utilization and influence of a community-based participatory nutrition promotion programme in rural Ethiopia: programme impact pathway analysis.

OBJECTIVE: A community-based participatory nutrition promotion (CPNP) programme, involving a 2-week group nutrition session, attempted to improve child feeding and hygiene. The implementation, utilization and influence of the CPNP programme were examined by programme impact pathway (PIP) analysis. DESIGN: Five CPNP programme components were evaluated: (i) degree of implementation; (ii) participants' perception of the nutrition sessions; (iii) participants' message recall; (iv) utilization of feeding and hygiene practices at early programme stage; and (v) participants' engagement in other programmes. SETTING: Habro and Melka Bello districts, Ethiopia. SUBJECTS: Records of 372 nutrition sessions, as part of a cluster-randomized trial, among mothers (n 876 in intervention area, n 914 in control area) from a household survey and CPNP participants (n 197) from a recall survey. RESULTS: Overall, most activities related to nutrition sessions were successfully operated with high fidelity (>90 %), but a few elements of the protocol were only moderately achieved. The recall survey among participants showed a positive perception of the sessions (~90 %) and a moderate level of message recall (~65 %). The household survey found that the CPNP participants had higher minimum dietary diversity at the early stage (34·0 v. 19·9 %, P=0·01) and a higher involvement in the Essential Nutrition Action (ENA) programme over a year of follow-up (28·2 v. 18·3 %; P<0·0001) compared with non-participants within the intervention area. CONCLUSIONS: Our PIP analysis suggests that CPNP was feasibly implemented, promoted a sustained utilization of proper feeding behaviours, and enhanced participation in the existing ENA programme. These findings provide a possible explanation to understanding CPNP's effectiveness

Imaging-based parcellations of the human brain

A defining aspect of brain organization is its spatial heterogeneity, which gives rise to multiple topographies at different scales. Brain parcellation — defining distinct partitions in the brain, be they areas or networks that comprise multiple discontinuous but closely interacting regions — is thus fundamental for understanding brain organization and function. The past decade has seen an explosion of in vivo MRI-based approaches to identify and parcellate the brain on the basis of a wealth of different features, ranging from local properties of brain tissue to long-range connectivity patterns, in addition to structural and functional markers. Given the high diversity of these various approaches, assessing the convergence and divergence among these ensuing maps is a challenge. Inter-individual variability adds to this challenge but also provides new opportunities when coupled with cross-species and developmental parcellation studies

Schooling for a Stateless Nation: The Predicament of Education without Consensus for Karen Refugees on the Thailand-Myanmar Border

This article addresses the issue of schooling for refugees, as members of a stateless nation, in the context of Karen refugees in Thailand. The authors used ethnographic methods of in-depth, semi-structured interviews and participant observation with over 250 residents of Mae La refugee camp. Our conceptual framework draws on theories of pedagogy for liberation and grassroots development. We found that, due to overlapping sources of authority with divergent visions of the future for refugee learners, the existential crisis of being members of a stateless nation is the most pressing issue for education to address. We suggest that a top-down approach to refugee education relying on technical solutions, while ignoring issues of history, power, and meaning-making, will ultimately fall short of being fundamentally transformative

“Putting on our people lens”: Lived Experience as Pedagogy

In the professional education of mental health practitioners, including occupational therapists, there has been a lack of meaningful inclusion of people labeled with mental illness into curricula, beyond guest speaker panels and presentations. This study explored the experiences of students, faculty, and ‘Experts by Experience’ within a mental health occupational therapy course that incorporated Experts with lived experience as co-facilitators of weekly fieldwork debriefs. The study utilized focus groups and interviews to understand the experiences of students, mental health faculty, and ‘Experts by Experience’. Key themes that emerged from the qualitative data analysis were organized under three broad categories: 1) Students experienced powerful insights, 2) Experts conveyed the complexity of the work, and 3) Faculty grew from co-creating learning experiences with the Experts. This research makes a significant contribution to occupational therapy education by shifting the Expert’s role beyond traditional speaker panels or storytelling. This broader responsibility elevated experiential knowledge into the realm of practice in clinical reasoning by shifting the context of the knowledge from storytelling to support practice reasoning. While this created significant learning opportunities for the students, it also did appear to cause emotional risk for the ‘Experts by Experience’. It is important that efforts to include ‘Experts by Experience’ in curriculum also include sources of support and financial remuneration

Neuromicrobiology, an emerging neurometabolic facet of the gut microbiome?

The concept of the gut microbiome is emerging as a metabolic interactome influenced by diet, xenobiotics, genetics, and other environmental factors that affect the host’s absorption of nutrients, metabolism, and immune system. Beyond nutrient digestion and production, the gut microbiome also functions as personalized polypharmacy, where bioactive metabolites that our microbes excrete or conjugate may reach systemic circulation and impact all organs, including the brain. Appreciable evidence shows that gut microbiota produce diverse neuroactive metabolites, particularly neurotransmitters (and their precursors), stimulating the local nervous system (i.e., enteric and vagus nerves) and affecting brain function and cognition. Several studies have demonstrated correlations between the gut microbiome and the central nervous system sparking an exciting new research field, neuromicrobiology. Microbiome-targeted interventions are seen as promising adjunctive treatments (pre-, pro-, post-, and synbiotics), but the mechanisms underlying host-microbiome interactions have yet to be established, thus preventing informed evidence-based therapeutic applications. In this paper, we review the current state of knowledge for each of the major classes of microbial neuroactive metabolites, emphasizing their biological effects on the microbiome, gut environment, and brain. Also, we discuss the biosynthesis, absorption, and transport of gut microbiota-derived neuroactive metabolites to the brain and their implication in mental disorders

Melanocortin-4 receptor gene: case-control study and transmission disequilibrium test confirm that functionally relevant mutations are compatible with a major gene effect for extreme obesity

We initially performed a mutation screen of the coding region of the MC4R in 808 extremely obese children and adolescents and 327 underweight or normal-weight controls allowing for a case-control study. A total of 16 different missense, nonsense, and frameshift mutations were found in the obese study group; five of these have not been observed previously. In vitro assays revealed that nine [the haplotype (Y35X; D37V) was counted as one mutation] of the 16 mutations led to impaired cAMP responses, compared with wild-type receptor constructs. In contrast, only one novel missense mutation was detected in the controls, which did not alter receptor function. The association test based on functionally relevant mutations was positive (P = 0.006, Fisher's exact test, one-sided). We proceeded by screening a total of 1040 parents of 520 of the aforementioned obese young index patients to perform transmission disequilibrium tests. The 11 parental carriers of functionally relevant mutations transmitted the mutation in 81.8% (P = 0.033; exact one-sided McNemar test). These results support the hypothesis that these MC4R mutations represent major gene effects for obesity

Maternal Obesity in Pregnancy Developmentally Programs Adipose Tissue Inflammation in Young, Lean Male Mice Offspring.

Obesity during pregnancy has a long-term effect on the health of the offspring including risk of developing the metabolic syndrome. Using a mouse model of maternal diet-induced obesity, we employed a genome-wide approach to investigate the microRNA (miRNA) and miRNA transcription profile in adipose tissue to understand mechanisms through which this occurs. Male offspring of diet-induced obese mothers, fed a control diet from weaning, showed no differences in body weight or adiposity at 8 weeks of age. However, offspring from the obese dams had up-regulated cytokine (Tnfα; P < .05) and chemokine (Ccl2 and Ccl7; P < .05) signaling in their adipose tissue. This was accompanied by reduced expression of miR-706, which we showed can directly regulate translation of the inflammatory proteins IL-33 (41% up-regulated; P < .05) and calcium/calmodulin-dependent protein kinase 1D (30% up-regulated; P < .01). We conclude that exposure to obesity during development primes an inflammatory environment in adipose tissue that is independent of offspring adiposity. Programming of adipose tissue miRNAs that regulate expression of inflammatory signaling molecules may be a contributing mechanism.This work was supported by Funding sources: National Council for the Improvement of Higher Education (CAPES - Brazil - BEX 10 594/13–2); National Counsel of Technological and Scientific Development (CNPq – Brazil – PDE/204416/ 2014–0); Medical Research Council (MC UU 12012/4 and MC UU12012/5), BBSRC (BB/M001636/1) and the Wellcome Trust (089940/Z/09/Z).This is the final version of the article.

Warren B. Davis and the Birth of Plastic Surgery in Philadelphia: A Historical Vignette

The field of plastic surgery, formally organized in 1931 with the founding of the American Society of Plastic and Reconstructive Surgery, was shaped in many ways by a small practice of Philadelphia physicians. At the center of the practice was Warren B. Davis, a Philadelphia otolaryngologist and plastics pioneer whose innovations in cleft palate surgery would lead to significant improvements in functional and cosmetic outcomes in his time. In addition to his own innovations, Davis was responsible for the training of John Reese, the inventor of the Reese dermatome that changed the face of burn medicine during World War II. Aside from his contributions to surgery and the founding of the American Society of Plastic and Reconstructive Surgery, Dr. Davis was also the founder and first editor of the Plastic and Reconstructive Surgery journal which to this day is the premiere, authoritative journal of plastic surgery. Lastly, Dr. Davis established a plastic surgical practice, now Jefferson Plastic Surgery. Unique in its longevity, this practice would continue to shape the field of plastic surgery and continues to improve lives today—109 years after its founding in 1913
