In the second half of the twentieth century, typhoon-triggered floods affected all sectors of society in the Philippines, but none more so than the urban poor, particularly the esteros-dwellers or shanty-town inhabitants, residing in the low-lying locales of Manila and a number of other cities on Luzon and the Visayas. The growing number of post-war urban poor in Manila, Cebu City and elsewhere, was largely due to the policy repercussions of rapid economic growth and impoverishment under the military-led Marcos regime. At this time in the early 1970s, rural poverty and environmental devastation increased rapidly, and on a hitherto unknown scale in the Philippines. Widespread corruption, crony capitalism and deforesting the archipelago caused large-scale forced migration, homelessness and a radically skewed distribution of income and assets that continued to favour elite interests.
Moths are a hyperdiverse taxon and contribute to important ecosystem services, including herbivory, pollination, and as food for other animals. Artificial light is an effective means by which to attract nocturnal moths for ecological study, but many traditional light-trapping approaches require the use of heavy, lead acid batteries, whereas novel light-emitting diodes (LEDs) use much lighter and energy-efficient lithium-ion batteries. Employing replicated forest stands being used for a longer-term study on the effects of Bacillus thuringiensis subsp. kurstaki (Btk) application, we assessed how traps fitted with either black-light fluorescent (BLF) or LED lights differed in the moth assemblages they attracted. The macromoth assemblages captured by the two light sources differed significantly in their composition, with some species almost exclusively collected by a particular light type. We collected significantly more moths in the BLF traps overall. However, we found a higher diversity of species using the LED light traps but only in the Btk–treated sites. We show that, although these lights appear to attract significantly different species assemblages, LEDs represent an effective, efficient, and environmentally safer approach for attracting macromoths. More empirical studies will help elucidate which species are most attracted to various light sources and if broader phylogenetic patterns exist.
In North America, less than 30% of children with complex CHD receive recommended follow-up for neurodevelopmental and psychosocial care. While rates of follow-up care at surgical centres have been described, little is known about similar services outside of surgical centres.
Methods:
This cohort study used Maine Health Data Organization’s All Payer Claims Data from 2015 to 2019 to identify developmental and psychosocial-related encounters received by children 0–18 years of age with complex CHD. Encounters were classified as developmental, psychological, and neuropsychological testing, mental health assessment interventions, and health and behaviour assessments and interventions. We analysed the association of demographic and clinical characteristics of children and the receipt of any encounter.
Results:
Of 799 unique children with complex CHD (57% male, 56% Medicaid, and 64% rural), 185 (23%) had at least one developmental or psychosocial encounter. Only 13 children (1.6%) received such care at a surgical centre. Developmental testing took place at a mix of community clinics/private practices (39%), state-based programmes (31%), and hospital-affiliated clinics (28%) with most encounters billing Medicaid (86%). Health and behavioural assessments occurred exclusively at hospital-affiliated clinics, predominately with Medicaid claims (82%). Encounters for mental health interventions, however, occurred in mostly community clinics/private practices (80%) with the majority of encounters billing commercial insurance (64%).
Conclusion:
Children with complex CHD in Maine access developmental and psychosocial services in locations beyond surgical centres. To better support the neurodevelopmental outcomes of their patients, CHD centres should build partnerships with these external providers.
The Ediacaran Subcommission of the International Commission on Stratigraphy is diligently working toward the goal of subdividing the Ediacaran Period into precise and useful chronostratigraphic units. As emphasized by Xiao and colleagues in 2016, one of the most effective tools in this endeavor will be the use of index fossils. Our special issue serves as a presentation of ongoing research efforts aimed at advancing this task and contains explorations into taxonomy, taphonomy, and the diversity of life during the Ediacaran Period.
The morphology of synthetic montmorillonite and hectorite was studied using electron microscopy and X-ray diffraction techniques. Interstratified montmorillonite-mica particles may be identified in these specimens by electron microscopy and electron diffraction techniques. Magnesium-substituted samples were found to exhibit an increasing amount of curling with increasing magnesium content except for the end-member magnesium clay. Synthetic hectorite clays do not necessarily have the same morphology as natural hectorite clays. A study was made also of the morphology of a series of samples obtained from a study of kinetics of crystallization. Boehmite and montmorillonite were the basic components of the system. It was found that the montmorillonite clay particles curled around the boehmite which had been adsorbed on the basal surfaces on the montmorillonite.
In ‘Early Learning in Plato’s Republic 7’, James Warren provides an analysis of Socrates’ account of the sort of early learning needed to produce philosopher-rulers in Republic 7 (521c–525a), namely a passage describing a very early encounter with questions that provoke thoughts about intelligible objects and stir up concepts in the soul. Warren explains how concepts of number, more specifically the concepts ‘one’, ‘two’, ‘a pair’, and so on, play an essential role in these very early stages of the ascent towards knowledge, and he stresses the continuity between the initial and very basic arithmetical concepts and the concepts involved in more demanding subjects taught in later stages of the educational curriculum. On this account, Socrates is prepared to ascribe to more or less everyone an acquaintance with some, albeit elementary, intelligible objects. This, in turn, can shed some light on broader debates in Platonic epistemology about the extent to which all people – not just those whom Socrates calls philosophers – have some conceptual grasp of intelligibles.
The objectives of the study were to determine the chemical composition and layer charge of smectite found in calcareous till of the Interior Plains region of western Canada and to examine the effects of acidification on alteration of the smectite. Samples of acidified and non-acidified (calcareous) late-Wisconsin till were obtained from four soil pits located immediately adjacent to an elemental sulfur block located in southern Alberta. Samples of the surface material (0–10 cm depth) had been subjected to extreme acidity for 25 years due to the oxidation of elemental sulfur and displayed pH values of about 2.0. Samples of the till obtained at depth (65–75 cm) remained calcareous with pH values between 7.3 and 7.6. A combination of analytical methods was used to determine the chemical composition of the smectite found in the samples. The layer charge of the smectite was determined independently using X-ray diffraction data for n-alkylammoniurn saturated specimens. Smectite found in the non-acidified calcareous material was characteristic of montmorillonite with a low content of Fe and very little substitution of Al for Si in the tetrahedral sheet. The smectite had a structural formula of M+0.40(Si3.96Al0.04)(Al1.56Fe3+0.10Mg0.33)O10(OH)2, which compared well with a mean value for layer charge of 0.399 mol(−)/O10(OH)2 determined using X-ray diffraction data for n-alkylammonium treated specimens. Smectite remaining in the till material subjected to extreme acidity underwent incongruent dissolution with a net loss of layer charge and preferential loss of octahedral Mg.
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.

The 2016–17 European outbreak of H5N8 HPAIV (Clade 2.3.4.4b) affected a wider range of avian species than the previous H5N8 outbreak (2014–15), including an incursion of H5N8 HPAIV into gamebirds in England. Natural infection of captive-reared pheasants (Phasianus colchicus) led to variable disease presentation; clinical signs included ruffled feathers, reluctance to move, bright green faeces, and/or sudden mortality. Several birds exhibited neurological signs (nystagmus, torticollis, ataxia). Birds exhibiting even mild clinical signs maintained substantial levels of virus replication and shedding, with preferential shedding via the oropharyngeal route. Gross pathology was consistent with HPAIV, in gallinaceous species but diphtheroid plaques in oropharyngeal mucosa associated with necrotising stomatitis were novel but consistent findings. However, minimal or modest microscopic pathological lesions were detected despite the systemic dissemination of the virus. Serology results indicated differences in the timeframe of exposure for each case (n = 3). This supported epidemiological conclusions confirming that the movement of birds between sites and other standard husbandry practices with limited hygiene involved in pheasant rearing (including several fomite pathways) contributed to virus spread between premises.
We examined whether preadmission history of depression is associated with less delirium/coma-free (DCF) days, worse 1-year depression severity and cognitive impairment.
Design and measurements:
A health proxy reported history of depression. Separate models examined the effect of preadmission history of depression on: (a) intensive care unit (ICU) course, measured as DCF days; (b) depression symptom severity at 3 and 12 months, measured by the Beck Depression Inventory-II (BDI-II); and (c) cognitive performance at 3 and 12 months, measured by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) global score.
Setting and participants:
Patients admitted to the medical/surgical ICU services were eligible.
Results:
Of 821 subjects eligible at enrollment, 261 (33%) had preadmission history of depression. After adjusting for covariates, preadmission history of depression was not associated with less DCF days (OR 0.78, 95% CI, 0.59–1.03 p = 0.077). A prior history of depression was associated with higher BDI-II scores at 3 and 12 months (3 months OR 2.15, 95% CI, 1.42–3.24 p = <0.001; 12 months OR 1.89, 95% CI, 1.24–2.87 p = 0.003). We did not observe an association between preadmission history of depression and cognitive performance at either 3 or 12 months (3 months beta coefficient −0.04, 95% CI, −2.70–2.62 p = 0.97; 12 months 1.5, 95% CI, −1.26–4.26 p = 0.28).
Conclusion:
Patients with a depression history prior to ICU stay exhibit a greater severity of depressive symptoms in the year after hospitalization.
In the pseudo-Platonic dialogue Axiochus, Socrates deploys a variety of arguments to soothe Axiochus’ fear of death. One of these is the ‘symmetry argument’ that tries to demonstrate that the state we will be in post mortem is no more harmful than the state we were in before birth. This argument is often associated with Epicureanism and with their commitment to the mortality of the soul, and it is therefore sometimes thought that Socrates’ use of it here is inconsistent with his commitment in the dialogue to the claim that each of us is in fact an immortal soul. This is also sometimes thought to show that the dialogue as a whole is clumsily constructed. I show how Socrates may deploy a symmetry argument and remain consistent with his other commitments.
Treatment-resistant schizophrenia (TRS) is associated with high levels of functional impairment, healthcare usage and societal costs. Cross-sectional studies may overestimate TRS rates because of selection bias.
Aims
We aimed to quantify TRS rates by using first-episode cohorts to improve resource allocation and clozapine access.
Method
We undertook a systematic review of TRS rates among people with first-episode psychosis and schizophrenia, with a minimum follow-up of 8 weeks. We searched PubMed, PsycINFO, EMBASE, CINAHL and the Cochrane Database of Systematic Reviews, and meta-analysed TRS rates from included studies.
Results
Twelve studies were included, totalling 11 958 participants; six studies were of high quality. The rate of TRS was 22.8% (95% CI 19.1–27.0%, P < 0.001) among all first-episode cohorts and 24.4% (95% CI 19.5–30.0%, P < 0.001) among first-episode schizophrenia cohorts. Subgroup sensitivity analyses by location of recruitment, TRS definition, study quality, time of data collection and retrospective versus prospective data collection did not lead to statistically significant differences in heterogeneity. In a meta-regression, duration of follow-up and percentage drop-out did not significantly affect the overall TRS rate. Men were 1.57 times more likely to develop TRS than women (95% CI 1.11–2.21, P = 0.010).
Conclusions
Almost a quarter of people with first-episode psychosis or schizophrenia will develop TRS in the early stages of treatment. When including people with schizophrenia who relapse despite initial response and continuous treatment, rates of TRS may be as high as a third. These high rates of TRS highlight the need for improved access to clozapine and psychosocial supports.
The relationship of soul to body was one of the earliest and most persistent questions in ancient thought. It emerges in the Homeric poems, where the psuchē is a breath-like stuff that animates the human being until it departs at death for the underworld, leaving the corpse (sōma or nekros) behind. In the Odyssey these souls are found lurking wraith-like in the underworld until they are revitalised by a sacrifice of blood which gives them a temporary power to think and speak again. Among Pythagoreans and others, the soul lives imprisoned in the body until it is liberated at death, only to be reincarnated for a new life in a new body in accordance with its merits. Plato embraces this theory in several of his dialogues, but even though the soul is a relatively autonomous substance it is nevertheless deeply affected by the conditions of the body it inhabits during life and the choices this embodied soul makes. Other early Greek thinkers regarded the soul as little more than the life force animating a body, a special kind of material stuff that accounts for the functions of a living animal but then disperses at death. Democritean atomism embraced this notion of soul, which was also common in the medical tradition.
