Objectives:
To evaluate and synthesise the evidence base on barriers and facilitators to accessing and using community-based social care in dementia.
Design:Mixed-methods systematic review
Setting:Community-based social care
Participants:People living with dementia and unpaid carers
Measurements:Seven databases were searched in March 2022, including English and German evidence published from 2005 focusing on inequalities in community-based social care for dementia across the globe. Titles and abstracts were screened by two reviewers, with all full texts screened by two reviewers also. Study quality was assessed using QualSyst.
Results:From 3,904 screened records, 39 papers were included. The majority of studies were qualitative, with 23 countries represented. Barriers and facilitators could be categorised into the following five categories/themes: Situational, psychological, interpersonal, structural, and cultural. Barriers were notably more prominent than facilitators, and were multi-faceted, with many factors hindering or facilitating access to social care linked together.
Conclusions:People with dementia and carers experience significant barriers in accessing care in the community, and a varied approach on multiple levels is required to address systemic and individual-level barriers to enable more equitable access to care for all.

Meeting the complex demands of conservation requires a multi-skilled workforce operating in a sector that is respected and supported. Although professionalization of conservation is widely seen as desirable, there is no consistent understanding of what that entails. Here, we review whether and how eight elements of professionalization observed in other sectors are applicable to conservation: (1) a defined and respected occupation; (2) official recognition; (3) knowledge, learning, competences and standards; (4) paid employment; (5) codes of conduct and ethics; (6) individual commitment; (7) organizational capacity; and (8) professional associations. Despite significant achievements in many of these areas, overall progress is patchy, and conventional concepts of professionalization are not always a good fit for conservation. Reasons for this include the multidisciplinary nature of conservation work, the disproportionate influence of elite groups on the development and direction of the profession, and under-representation of field practitioners and of Indigenous peoples and local communities with professional-equivalent skills. We propose a more inclusive approach to professionalization that reflects the full range of practitioners in the sector and the need for increased recognition in countries and regions of high biodiversity. We offer a new definition that characterizes conservation professionals as practitioners who act as essential links between conservation action and conservation knowledge and policy, and provide seven recommendations for building a more effective, inclusive and representative profession.

Background
Studying phenotypic and genetic characteristics of age at onset (AAO) and polarity at onset (PAO) in bipolar disorder can provide new insights into disease pathology and facilitate the development of screening tools.
AimsTo examine the genetic architecture of AAO and PAO and their association with bipolar disorder disease characteristics.
MethodGenome-wide association studies (GWASs) and polygenic score (PGS) analyses of AAO (n = 12 977) and PAO (n = 6773) were conducted in patients with bipolar disorder from 34 cohorts and a replication sample (n = 2237). The association of onset with disease characteristics was investigated in two of these cohorts.
ResultsEarlier AAO was associated with a higher probability of psychotic symptoms, suicidality, lower educational attainment, not living together and fewer episodes. Depressive onset correlated with suicidality and manic onset correlated with delusions and manic episodes. Systematic differences in AAO between cohorts and continents of origin were observed. This was also reflected in single-nucleotide variant-based heritability estimates, with higher heritabilities for stricter onset definitions. Increased PGS for autism spectrum disorder (β = −0.34 years, s.e. = 0.08), major depression (β = −0.34 years, s.e. = 0.08), schizophrenia (β = −0.39 years, s.e. = 0.08), and educational attainment (β = −0.31 years, s.e. = 0.08) were associated with an earlier AAO. The AAO GWAS identified one significant locus, but this finding did not replicate. Neither GWAS nor PGS analyses yielded significant associations with PAO.
ConclusionsAAO and PAO are associated with indicators of bipolar disorder severity. Individuals with an earlier onset show an increased polygenic liability for a broad spectrum of psychiatric traits. Systematic differences in AAO across cohorts, continents and phenotype definitions introduce significant heterogeneity, affecting analyses.

Background:
Spinal muscular atrophy (SMA) is a devastating rare disease that affects individuals regardless of ethnicity, gender, and age. The first-approved disease-modifying therapy for SMA, nusinursen, was approved by Health Canada, as well as by American and European regulatory agencies following positive clinical trial outcomes. The trials were conducted in a narrow pediatric population defined by age, severity, and genotype. Broad approval of therapy necessitates close follow-up of potential rare adverse events and effectiveness in the larger real-world population.
Methods:The Canadian Neuromuscular Disease Registry (CNDR) undertook an iterative multi-stakeholder process to expand the existing SMA dataset to capture items relevant to patient outcomes in a post-marketing environment. The CNDR SMA expanded registry is a longitudinal, prospective, observational study of patients with SMA in Canada designed to evaluate the safety and effectiveness of novel therapies and provide practical information unattainable in trials.
Results:The consensus expanded dataset includes items that address therapy effectiveness and safety and is collected in a multicenter, prospective, observational study, including SMA patients regardless of therapeutic status. The expanded dataset is aligned with global datasets to facilitate collaboration. Additionally, consensus dataset development aimed to standardize appropriate outcome measures across the network and broader Canadian community. Prospective outcome studies, data use, and analyses are independent of the funding partner.
Conclusion:Prospective outcome data collected will provide results on safety and effectiveness in a post-therapy approval era. These data are essential to inform improvements in care and access to therapy for all SMA patients.

Tight Entrance Cave (TEC) in southwestern Australia provides a Pleistocene sequence documenting the extinction of 14 large mammal species. This record has been interpreted as indicating that extinctions did not occur during or before the penultimate glacial maximum (PGM) and that humans played a primary role in the extinctions. However, it remains possible that the majority of extinct megafauna persisted no later than the PGM. The TEC extinctions correspond with vegetation change, a cooling/drying trend, increased biomass burning, and increasingly unstable small mammal communities. The initiation of these trends predates human arrival on the continent and implies environmentally mediated extinctions.

Early Archaic human skeletal remains found in a burial context in Lapa do Santo in east-central Brazil provide a rare glimpse into the lives of hunter-gatherer communities in South America, including their rituals for dealing with the dead. These included the reduction of the body by means of mutilation, defleshing, tooth removal, exposure to fire and possibly cannibalism, followed by the secondary burial of the remains according to strict rules. In a later period, pits were filled with disarticulated bones of a single individual without signs of body manipulation, demonstrating that the region was inhabited by dynamic groups in constant transformation over a period of centuries.

Background
National Institute for Health and Care Excellence have recommended faecal calprotectin (FC) testing as an option in adults with lower gastrointestinal symptoms for whom specialist investigations are being considered, if cancer is not suspected and it is used to support a diagnosis of inflammatory bowel disease (IBD) or irritable bowel syndrome. York Hospital and Vale of York Clinical Commissioning Group have developed an evidence-based care pathway to support this recommendation for use in primary care. It incorporates a higher FC cut-off value, a ‘traffic light’ system for risk and a clinical management pathway.
ObjectivesTo evaluate this care pathway.
MethodsThe care pathway was introduced into five primary care practices for a period of six months and the clinical outcomes of patients were evaluated. Negative and positive predictive values (NPV and PPV) were calculated. GP feedback of the care pathway was obtained by means of a web-based survey. Comparator gastroenterology activity in a neighbouring trust was obtained.
ResultsThe care pathway for FC in primary care had a 97% NPV and a 40% PPV. This was better than GP clinical judgement alone and doubled the PPV compared with the standard FC cut-off (<50 mcg/g), without affecting the NPV. In total, 89% of patients with IBD had an FC>250 mcg/g and were diagnosed by ‘straight to test’ colonoscopy within three weeks. The care pathway was considered helpful by GPs and delivered a higher diagnostic yield after secondary care referral (21%) than the conventional comparator pathway (5%).
ConclusionsA care pathway for the use of FC that incorporates a higher cut-off value, a ‘traffic light’ system for risk and supports clinical decision making can be achieved safely and effectively. It maintains the balance between a high NPV and an acceptable PPV. A modified care pathway for the use of FC in primary care is proposed.

The provision of surgery within humanitarian crises is complex, requiring coordination and cooperation among all stakeholders. During the 2011 Humanitarian Action Summit best practice guidelines were proposed to provide greater accountability and standardization in surgical humanitarian relief efforts. Surgical humanitarian relief planning should occur early and include team selection and preparation, appropriate disaster-specific anticipatory planning, needs assessment, and an awareness of local resources and limitations of cross-cultural project management. Accurate medical record keeping and timely follow-up is important for a transient surgical population. Integration with local health systems is essential and will help facilitate longer term surgical health system strengthening.

Limb amputations are frequently performed as a result of trauma inflicted during conflict or disasters. As demonstrated during the 2010 earthquake in Haiti, coordinating care of these patients in austere settings is complex. During the 2011 Humanitarian Action Summit, consensus statements were developed for international organizations providing care to limb amputation patients during disasters or humanitarian emergencies. Expanded planning is needed for a multidisciplinary surgical care team, inclusive of surgeons, anesthesiologists, rehabilitation specialists and mental health professionals. Surgical providers should approach amputation using an operative technique that optimizes limb length and prosthetic fitting. Appropriate anesthesia care involves both peri-operative and long-term pain control. Rehabilitation specialists must be involved early in treatment, ideally before amputation, and should educate the surgical team in prosthetic considerations. Mental health specialists must be included to help the patient with community reintegration. A key step in developing local health systemsis the establishment of surgical outcomes monitoring. Such monitoring can optimizepatient follow-up and foster professional accountability for the treatment of amputation patients in disaster settings and humanitarian emergencies.

Flooding is an inexpensive cultural practice used for pest management in Massachusetts cranberry (Vaccinium macrocarpon Ait.) production. This project examined the use of short-term floods (<72 h) for dodder (Cuscuta gronovii Willd.) management under controlled conditions. Using incubators, seed was submerged in water for 0, 24 and 48 h at 10, 15 and 20°C (simulating spring water temperatures) and 0, 12, 24, 36 and 48 h at 15, 20 and 25°C (simulating summer water temperatures). Two 1-year controlled studies (field and greenhouse) evaluated three flood durations (0, 24 and 48 h) and four flood initiations (1, 2, 3 and 4 weeks after early seedling emergence (AEE)). Treated seeds were planted to cranberry vines and to Petri dishes; percent germination, degree of dodder attachment and dodder biomass data were collected. Treatments had limited effect on seed germination. Flooding 4 weeks AEE resulted in the lowest mean attachment ratings and dodder stem biomass on cranberry. This preliminary work provides evidence that flooding may retard dodder stem growth rather than reducing seed germination and that floods initiated after some time has elapsed after early emergence may be more effective than those initiated closer to the time of seedling emergence. More information is needed to thoroughly understand the processes involved; however, small projects such as this can provide interim guidelines that growers can immediately consider when deciding on a dodder management program.

Summary
MANY playhouses during the English Renaissance employed a trapdoor on their stage. Several types of evidence point to this fact, primarily drawings and stage directions, both proper and embedded. Much of the evidence is vague, such as the stage direction, “Hell is discovered,” in the second quarto of Marlowe's Doctor Faustus. Other evidence, however, is clear and explicit, such as the call for two actors to be “ready to open the trapdoor” in the manuscript of Massinger's Believe As Ye List.
It is not easy to identify which theatres had trapdoors and which did not; none of the extant playhouse drawings clearly identify the theatre to which they belong, save only the DeWitt drawing of the Swan. It is even more difficult to ascertain specific details about a particular theatre's trapdoor, including its size, location on the platform, and opening mechanism—in other words, how each individual trapdoor differed from the rest. For despite Robert Cohen's assertion that each theatre was equipped with “a 4-by-4-foot trap door,” each was different.
More important than the physical structure of the trapdoors is the effect they had on Renaissance plays. Many playwrights, including William Shakespeare, wrote their plays for specific companies; those companies generally operated out of a primary space. While writing for the Lord Chamberlain's Men and later the King's Men, Shakespeare wrote many of his earlier plays for production at the Globe and later for the Blackfriars. The benefits and limitations of each trapdoor dictated how playwrights would utilize them.

Summary
Introduction
The aquatic and terrestrial components of riparian systems provide ecological opportunities for many species of mammals. The importance of riparian habitat to wildlife populations has been documented in a wide range of habitats in North America: the midwestern United States (Stauffer and Best 1980), desert southwest (England et al. 1984), Rocky Mountains (Knopf 1985), Oregon (Anthony et al. 1987, Doyle 1990, McComb et al. 1993, Gomez and Anthony 1998, Kauffman et al. 2001), Washington (O'Connell et al. 1993, Kelsey and West 1998, Kauffman et al. 2001), and the Okanogan Highlands of British Columbia (Gyug 2000). These studies indicate that wildlife species richness is high in these ecosystems, and use of riparian zones by some species is disproportionately higher than in other areas. Although this is especially true in the more arid regions of North America (Johnson and Jones 1977, Brinson et al. 1981), this pattern can also be found in mesic forests of the Pacific Northwest. For example, Thomas et al. (1979) report that 285 of the 378 terrestrial wildlife species in the Blue Mountains of Oregon and Washington are found exclusively or more commonly in riparian areas, and Oakley et al. (1985) report similar patterns of 359 of the 414 wildlife species using riparian zones of western Washington and Oregon forests. Kauffman et al. (2001) estimate that 53% of the 593 wildlife species that occur in Washington and Oregon use riparian zones, whereas riparian zones and wetlands constitute only 1% to 2% of the landscape.

Summary
Small mammals are important components of western forest ecosystems. Their interactions with other organisms and the physical environment are complex. Small mammals are effective predators on seeds, vegetation, and insects, and may influence patterns of forest regeneration (Sullivan 1979, Christy and Mack 1984). Dispersal of seeds, mycorrhizal fungi, and nitrogen-fixing bacteria by small mammals may also affect plant diversity (Maser et al. 1978, Verts and Carraway 1998, Luoma et al. 2003). In addition, small mammals are prey for many carnivorous taxa, and changes in small-mammal abundance may affect the distribution and habitat use of their predators (Carey et al. 1992).
Understanding patterns of abundance and distribution of small mammals and how these species influence forest function and biodiversity are basic ecological problems relevant to both economic and conservation concerns. Exploration of these fundamental ecological relationships is challenging, however, because of the secretive nature of small mammals and their activities at night (e.g., deer mice (Peromyscus spp.)), below ground (e.g., gophers (Thomomys spp.) and moles (Scalopus spp.)), at the soil–vegetation interface (e.g., red-backed voles (Clethrionomys spp.) and shrews (Sorex spp.)), and in all levels of the canopy (e.g., flying squirrels (Glaucomys spp.) and tree squirrels (Tamiasciurus spp.)) (Aubry et al. 2003). In this chapter, we emphasize the forest-floor fauna, although not all species discussed confine themselves to the ground stratum (e.g., chipmunks (Tamias spp.) and woodrats (Neotoma spp.)).

Summary
Introduction
Adolph Schultz's famous diagram (Fig. 6.1) aged well: human life history is characterised by a long juvenile period (weaning to reproductive maturity), and a long post-reproductive lifespan in females. Table 6.1 compares human and great ape life history parameters and invariants of Charnov (1993). Notable here are low adult mortality, high fertility squeezed into a reproductive span similar in length to that of Pan (thus, shorter interbirth intervals), late age at first reproduction and great length of the juvenile period.
How do we explain these differences between our nearest relatives and ourselves? This chapter summarises some recent attempts to use life history models on data from contemporary hunter–gatherers, and other noncontracepting populations with little access to modern medicine (see also Borgerhoff Mulder, 1991; Hill, 1993; and for a comprehensive review of hunter–gatherer research, Kelley, 1995).
Trade-off between numbers and care of offspring
Hill and Hurtado (1996) examine interbirth interval and the trade-off between increased fertility and increased infant and child mortality among Ache foragers in Paraguay. As in other populations, after controlling for early death of a previous infant, mother's age, and mother's weight, shorter interbirth intervals are accompanied by higher infant and child mortality. But, in contrast to Blurton Jones (1986; for discussion of Harpending's (1994) critiques see Blurton Jones, 1994; for Hill and Hurtado's results, see Blurton Jones, 1996), they found that this effect was much too weak to render the observed intervals optimal. Ache values predict that the optimal interbirth interval would be much shorter than is observed. Hill and Hurtado discuss possible reasons, suggesting that there must be costs to very short intervals that we have yet to appreciate.
