Welcome to the first issue of the Journal of Evolution and Health! The Journal of Evolution and Health is the peer-reviewed, open-access journal of the Ancestral Health Society, a community of scientists, healthcare professionals, and laypersons who collaborate to understand health challenges from an evolutionary perspective.

Comparison Of Longitudinal Sciatic Nerve Movement With Different Mobilization Exercises: An In Vivo Study Utilizing Ultrasound Imaging, Richard Ellis, Wayne Hing, Peter Mcnair

Wayne Hing

Study Design: Controlled laboratory study using a single-group, within-subjects comparison. Objectives: To determine whether different types of neural mobilization exercises are associated with differing amounts of longitudinal sciatic nerve excursion measured in vivo at the posterior midthigh region.

Background: Recent research focusing on the upper limb of healthy subjects has shown that nerve excursion differs significantly between different types of neural mobilization exercises. This has not been examined in the lower limb. It is important to initially examine the influence of neural mobilization on peripheral nerve excursion in healthy people to identify peripheral nerve excursion impairments under conditions in which …

Poor Description Of Non-Pharmacological Interventions: Analysis Of Consecutive Sample Of Randomised Trials, Tammy Hoffmann, Chrissy Erueti, Paul Glasziou

Chrissy Erueti

Objectives: To evaluate the completeness of descriptions of non-pharmacological interventions in randomised trials, identify which elements are most frequently missing, and assess whether authors can provide missing details. Design: Analysis of consecutive sample of randomised trials of non-pharmacological interventions. Data sources and study selection: All reports of randomised trials of non-pharmacological interventions published in 2009 in six leading general medical journals; 133 trial reports, with 137 interventions, met the inclusion criteria. Data collection Using an eight item checklist, two raters assessed the primary full trial report, plus any reference materials, appendices, or websites. Questions about missing details were emailed to …

Cytotoxic Lymphocyte Micrornas As Prospective Biomarkers For Chronic Fatigue Syndrome/Myalgic Encephalomyelitis, Ekua Brenu, Kevin Ashton, Mieke Van Driel, Donald Staines, Daniel Peterson, Gunn Atkinson, Sonia Marshall-Gradisnika

Kevin Ashton

Background: Immune dysfunction associated with a disease often has a molecular basis. A novel group of molecules known as microRNAs (miRNAs) have been associated with suppression of translational processes involved in cellular development and proliferation, protein secretion, apoptosis, immune function and inflammatory processes. MicroRNAs may be implicated in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME), where immune function is impaired. The objective of this study was to determine the association between miRNAs in cytotoxic cells and CFS/ME. Methods: Natural Killer (NK) and CD8+T cells were preferentially isolated from peripheral blood mononuclear cells from all participants (CFS/ME, n = 28; mean age = …

Voluntary Running In Mice Beneficially Modulates Myocardial Ischemic Tolerance, Signaling Kinases, And Gene Expression Patterns, Boris Budiono, Louise See Hoe, Jason Peart, Surendran Sabapathy, Kevin Ashton, Luke Haseler, John Headrick

Kevin Ashton

Exercise triggers hormesis, conditioning hearts against damaging consequences of subsequent ischemia-reperfusion (I/R). We test whether “low-stress” voluntary activity modifies I/R tolerance and molecular determinants of cardiac survival. Male C57BL/6 mice were provided 7-day access to locked (7SED) or rotating (7EX) running-wheels before analysis of cardiac prosurvival (Akt, ERK 1/2) and prodeath (GSK3β) kinases, transcriptomic adaptations, and functional tolerance of isolated hearts to 25-min ischemia/45-min reperfusion. Over 7 days, 7EX mice increased running from 2.1 ± 0.2 to 5.3 ± 0.3 km/day (mean speed 38 ± 2 m/min), with activity improving myocardial I/R tolerance: 7SED hearts recovered 43 ± 3% of …

Longitudinal Investigation Of Natural Killer Cells And Cytokines In Chronic Fatigue Syndrome/Myalgic Encephalomyelitis, Ekua Brenu, Mieke Van Driel, Donald Staines, Kevin Ashton, Sharni Hardcastle, James Keane, Lotti Tajouri, Daniel Peterson, Sandra Ramos, Sonya Marshall-Gradisnik

Kevin Ashton

Background: Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is an etiologically unexplained disorder characterised by irregularities in various aspects of the immunological function. Presently, it is unknown whether these immunological changes remain consistent over time. This study investigates Natural Killer (NK) cell cytotoxic activity, NK cell subsets (CD56brightCD16- and CD56dimCD16+) and cytokines, over the course of a12 month period in patients with CFS/ME. Methods: The participants in the study comprised 65 (47.2 ± 11.5 years) CFS/ME participants and 21 (45.2 ±9.3 years) non-fatigued controls. Flow cytometry protocols were used to assess NK subsets and NK cytotoxic activity at various time points that …

Perceptions Of Medical Students And Their Supervisors Of The Preparation Of Students For Clinical Placement In Obstetrics And Gynecology, Patricia Johnson, Patricia Green, Peter Jones, Heather James

Patricia Johnson

Background: Research is limited regarding the adequacy of preparation of medical students for their placement in obstetrics and gynecology. The aim of this study was to determine the perceptions of a cohort of undergraduate medical students from an Australian university and their clinical supervisors of the on-campus preparation of students for their clinical rotation in obstetrics and gynecology. Methods: We used a descriptive exploratory qualitative research approach and purposive sampling to address the aim of the study. Ten undergraduate medical students and 4 of their supervisors participated in the study. Data were collected from focus group discussions, follow-up interviews, and …

Lexical-Semantic Representation In Bilingual Aphasia: Findings From Semantic Priming And Cognate Repetition Priming, Samantha Siyambalapitiya, Helen Chenery, David Copland

Helen Chenery

BACKGROUND: While many studies have investigated the nature of language organisation in monolingual speakers with aphasia, our understanding of bilingual aphasia lags far behind. Only a handful of studies have employed on-line psycholinguistic experimental methods to explore the nature of language representation and processing in bilingual speakers with aphasia. Improving our understanding of how language is organised and processed in bilingual speakers with aphasia is central to the development of effective impairment-level language treatments. Cognate/noncognate representation and semantic representation are two key aspects of bilingual language organisation that are yet to be explored in depth in bilingual speakers with aphasia. …
