Just as there are many cultures within the world, so also are there many practices, beliefs, myths, values, and traditions within each culture. These unique ways of being can often present challenging frames of reference that may prevent a whole perspective from being attained. This essay examines the contextual formation of culture and the fundamentals intricate to the search for universal values. An illumination is also provided upon some of the major and extreme forms of cultural practices that may pose difficulty in achieving such a goal.

This exploratory study examined the combat and related experiences of United States (U.S.) veterans of the Iraq War. The examination was conducted using Irvin Yalom’s description of the four ultimate life concerns of meaning and meaninglessness, freedom and determinism, isolation and community, and life and death for understanding war and combat experiences. This study utilized a narrative theoretical approach that examined fifty interview statements of veterans from the Iraq War through Yalom’s ultimate life concerns. I found that looking at these veterans’ experiences in the context of Yalom’s concerns revealed ways war experiences can affect individual functioning postwar. The research question of this study asked if U.S. combat veterans of the Iraq War could be candidates for an existential-integrative (EI) approach to therapy. Specifically, this study combined Rollo May’s understanding of human experiences with Kirk J. Schneider’s existential-integrative perspective as a means for providing integrative healing from war-related experiences (e.g., combat). A major implication of this dissertation was that existential-integrative therapy might support the development of a positive post-war identity, but that substantiation of this claim is needed through outcome-based research.

Potent marine neurotoxins known as brevetoxins are produced by the 'red tide' dinoflagellate Karenia brevis. They kill large numbers of fish and cause illness in humans who ingest toxic filter-feeding shellfish or inhale toxic aerosols. The toxins are also suspected of having been involved in events in which many manatees and dolphins died, but this has usually not been verified owing to limited confirmation of toxin exposure, unexplained intoxication mechanisms and complicating pathologies. Here we show that fish and seagrass can accumulate high concentrations of brevetoxins and that these have acted as toxin vectors during recent deaths of dolphins and manatees, respectively. Our results challenge claims that the deleterious effects of a brevetoxin on fish (ichthyotoxicity) preclude its accumulation in live fish, and they reveal a new vector mechanism for brevetoxin spread through food webs that poses a threat to upper trophic levels.

IntroductionSymptomatic disc degeneration is a common cause of low back pain. Recently, the prevalence of low back pain has swiftly risen leading to increased patient disability and loss of work. The increase in back pain also coincides with a rapid rise in patient medical comorbidities. However, a comprehensive study evaluating a link between patient’s medical comorbidities and their influence on lumbar intervertebral disc morphology is lacking in the literature.MethodsElectronic medical records (EMR) were retrospectively reviewed to determine patient-specific medical characteristics. Magnetic resonance imaging (MRI) was evaluated for lumbar spine intervertebral disc desiccation and height loss according to the Griffith-modified Pfirrmann grading system. Bivariate and multivariable linear regression analyses assessed strength of associations between patient characteristics and lumbar spine Pfirrmann grade severity (Pfirrmann grade of the most affected lumbar spine intervertebral disc) and cumulative grades (summed Pfirrmann grades for all lumbar spine intervertebral discs).ResultsIn total, 605 patients (304 diabetics and 301 non-diabetics) met inclusion criteria. Bivariate analysis identified older age, diabetes, American Society of Anesthesiologists (ASA) class, hypertension, chronic obstructive pulmonary disease (COPD), peripheral vascular disease, and hypothyroidism as being strongly associated with an increasing cumulative Pfirrmann grades. Multivariable models similarly found an association linking increased cumulative Pfirrmann grades with diabetes, hypothyroidism, and hypertension, while additionally identifying non-white race, heart disease, and previous lumbar surgery. Chronic pain, depression, and obstructive sleep apnea (OSA) were associated with increased Pfirrmann grades at the most affected level without an increase in cumulative Pfirrmann scores. Glucose control was not associated with increasing severity or cumulative Pfirrmann scores.ConclusionThese findings provide specific targets for future studies to elucidate key mechanisms by which patient-specific medical characteristics contribute to the development and progression of lumbar spine disc desiccation and height loss.Level of evidenceIII (retrospective cohort).

Citizen science video games are designed primarily for users already inclined to contribute to science, which severely limits their accessibility for an estimated community of 3 billion gamers worldwide. We created Borderlands Science ( BLS ), a citizen science activity that is seamlessly integrated within a popular commercial video game played by tens of millions of gamers. This integration is facilitated by a novel game-first design of citizen science games, in which the game design aspect has the highest priority, and a suitable task is then mapped to the game design. BLS crowdsources a multiple alignment task of 1 million 16S ribosomal RNA sequences obtained from human microbiome studies. Since its initial release on 7 April 2020, over 4 million players have solved more than 135 million science puzzles, a task unsolvable by a single individual. Leveraging these results, we show that our multiple sequence alignment simultaneously improves microbial phylogeny estimations and UniFrac effect sizes compared to state-of-the-art computational methods. This achievement demonstrates that hyper-gamified scientific tasks attract massive crowds of contributors and offers invaluable resources to the scientific community. Gamification of the multiple sequence alignment problem improves microbial phylogeny estimates.

Background Patient and Public Involvement and Engagement (PPIE) is an essential element of any clinical trial, to ensure that the research design and resources are acceptable and the trial produces findings that are relevant to research participants and service-users. The WILL (When to Induce Labour to Limit risk in pregnancy hypertension) Trial Management Team involved a group of patient and public members to develop an infographic, for service-users and -providers, to communicate the risks of chronic and gestational hypertension at term gestational age. Methods Based on national resources in the UK for PPIE, including those from the National Institute for Health and Care Research (NIHR) and Health Research Authority, active trial sites (all in the UK) were approached to invite women with pregnancy hypertension to the PPIE group, and advertisements were placed on the Action on Pre-Eclampsia Charity (APEC) and NIHR People in Research websites. PPIE resources were established by the Trial Management Team and virtual meetings with the PPIE members held to co-design and develop the infographic from existing trial materials, using Microsoft Publisher. Results Seven diverse PPIE members were involved, six from NIHR People in Research and one from APEC. No members were engaged from active sites. From initial set-up to REC approval of the infographic took 9 months, and a considerable time commitment from the Trial Manager and Senior Research Midwives, to navigate practicalities (e.g. team consensus-building). Four meetings were held and 15 iterations of the infographic were developed with the group. The infographic incorporated requests from PPIE members for a design that was inclusive of all races, cultures, abilities and genders. Discussions with PPIE group members improved our understanding of the acceptability of the trial intervention to some cultures. The Research Ethics Committee (REC) requested revisions to PPIE-approved wording about the risk of stillbirth, from ‘1 in 1000’ to ‘small increased risk’ prior to issuing approval for use. Conclusions More practical support would be useful for researchers seeking to establish PPIE groups, and RECs reviewing resources that are co-produced. Our case study provides a practical, step-by-step account of establishing a PPIE group without a funded co-lead, highlighting strengths such as the diversity of members, the incorporation of cultural perspectives, and the development of inclusive patient-facing materials. These findings add to PPIE practice by offering operational guidance, lessons learned and a summary checklist as an additional resource that can complement existing high-level frameworks.

Background As a pragmatic randomised timing-of-birth trial, WILL adapted its trial procedures in response to the COVID-19 pandemic. These are reviewed here to inform post-pandemic trial methodology. Methods The trial (internal pilot) paused in March 2020, re-opened in July 2020, and is currently recruiting in 37 UK NHS consultant-led maternity units. We evaluated pandemic adaptations made to WILL processes and surveyed sites for their views of these changes (20 sites, videoconference). Results Despite 88% of sites favouring an electronic investigator site file (ISF), information technology requirements and clinical trial unit (CTU) operating procedures mandated the ongoing use of paper ISFs; site start-up delays resulted from restricted access to the CTU. Site initiation visits (SIVs) were conducted remotely; 50% of sites preferred remote SIVs and 44% felt that it was trial-dependent, while few preferred SIVs in-person as standard procedure. The Central team felt remote SIVs provided scheduling and attendance flexibility (for sites and trial staff), the option of recording discussions for missing or future staff, improved efficiency by having multiple sites attend, and time and cost savings; the negative impact on rapport-building and interaction was partially mitigated over time with more familiarity with technology and new ways-of-working. Two methods of remote consent were developed and used by 30/37 sites and for 54/156 recruits. Most (86%) sites using remote consenting felt it improved recruitment. For remote data monitoring (5 sites), advantages were primarily for the monitor (e.g. flexibility, no time constraints, reduced cost), and disadvantages primarily for the sites (e.g. document and access preparation, attendance at a follow-up meeting), but 81% of sites desired having the option of remote monitoring post-pandemic. Conclusions COVID adaptations to WILL trial processes improved the flexibility of trial delivery, for Central and site staff, and participants. Flexibility to use these strategies should be retained post-pandemic. Trial registration ISRCTN77258279. Registered on 05 December 2018.
