Patients with hematological malignancies are at high risk of infections due to both the disease and the associated treatments. The use of immunoglobulin (Ig) to prevent infections is increasing in this population, but its cost effectiveness is unknown. This trial-based economic evaluation aimed to compare the cost effectiveness of prophylactic Ig with prophylactic antibiotics in patients with hematological malignancies.
Methods
The economic evaluation used individual patient data from the RATIONAL feasibility trial, which randomly assigned 63 adults with chronic lymphocytic leukemia, multiple myeloma, or lymphoma to prophylactic Ig or prophylactic antibiotics. The following two analyses were conducted to estimate the cost effectiveness of the two treatments over the 12-month trial period from the perspective of the Australian health system:
(i) a cost-utility analysis (CUA) to assess the incremental cost per quality-adjusted life-year (QALY) gained using data collected with the EuroQol 5D-5L questionnaire; and
(ii) a cost-effectiveness analysis (CEA) to assess the incremental cost per serious infection prevented (grade ≥3) and per infection prevented (any grade).
Results
The total cost per patient was significantly higher in the Ig arm than in the antibiotic arm (difference AUD29,140 [USD19,000]). There were non-significant differences in health outcomes between the treatment arms: patients treated with Ig had fewer QALYs (difference −0.072) and serious infections (difference −0.26) than those given antibiotics, but more overall infections (difference 0.76). The incremental cost-effectiveness from the CUA indicated that Ig was more costly than antibiotics and associated with fewer QALYs. In the CEA, Ig costed an additional AUD111,262 (USD73,000) per serious infection prevented, but it was more costly than antibiotics and associated with more infections when all infections were included.
Conclusions
These results indicate that, on average, Ig prophylactic treatment may not be cost effective compared with prophylactic antibiotics for the group of patients with hematological malignancies recruited to the RATIONAL feasibility trial. Further research is needed to confirm these findings in a larger population and over the longer term.
Evidence on the impact of the pandemic on healthcare presentations for self-harm has accumulated rapidly. However, existing reviews do not include studies published beyond 2020.
Aims
To systematically review evidence on presentations to health services following self-harm during the COVID-19 pandemic.
Method
A comprehensive search of databases (WHO COVID-19 database; Medline; medRxiv; Scopus; PsyRxiv; SocArXiv; bioRxiv; COVID-19 Open Research Dataset, PubMed) was conducted. Studies published from 1 January 2020 to 7 September 2021 were included. Study quality was assessed with a critical appraisal tool.
Results
Fifty-one studies were included: 57% (29/51) were rated as ‘low’ quality, 31% (16/51) as ‘moderate’ and 12% (6/51) as ‘high-moderate’. Most evidence (84%, 43/51) was from high-income countries. A total of 47% (24/51) of studies reported reductions in presentation frequency, including all six rated as high-moderate quality, which reported reductions of 17–56%. Settings treating higher lethality self-harm were overrepresented among studies reporting increased demand. Two of the three higher-quality studies including study observation months from 2021 reported reductions in self-harm presentations. Evidence from 2021 suggests increased numbers of presentations among adolescents, particularly girls.
Conclusions
Sustained reductions in numbers of self-harm presentations were seen into the first half of 2021, although this evidence is based on a relatively small number of higher-quality studies. Evidence from low- and middle-income countries is lacking. Increased numbers of presentations among adolescents, particularly girls, into 2021 is concerning. Findings may reflect changes in thresholds for help-seeking, use of alternative sources of support and variable effects of the pandemic across groups.
Wetland sediments are valuable archives of environmental change but can be challenging to date. Terrestrial macrofossils are often sparse, resulting in radiocarbon (14C) dating of less desirable organic fractions. An alternative approach for capturing changes in atmospheric 14C is the use of terrestrial microfossils. We 14C date pollen microfossils from two Australian wetland sediment sequences and compare these to ages from other sediment fractions (n = 56). For the Holocene Lake Werri Berri record, pollen 14C ages are consistent with 14C ages on bulk sediment and humic acids (n = 14), whilst Stable Polycyclic Aromatic Carbon (SPAC) 14C ages (n = 4) are significantly younger. For Welsby Lagoon, pollen concentrate 14C ages (n = 21) provide a stratigraphically coherent sequence back to 50 ka BP. 14C ages from humic acid and >100 µm fractions (n = 13) are inconsistent, and often substantially younger than pollen ages. Our comparison of Bayesian age-depth models, developed in Oxcal, Bacon and Undatable, highlight the strengths and weaknesses of the different programs for straightforward and more complex chrono-stratigraphic records. All models display broad similarities but differences in modeled age-uncertainty, particularly when age constraints are sparse. Intensive dating of wetland sequences improves the identification of outliers and generation of robust age models, regardless of program used.
The coronavirus disease 2019 (COVID-19) created major disruptions at academic centers and healthcare systems globally. Clinical and Translational Science Awards (CTSA) fund hubs supported by the National Center for Advancing Translational Sciences provideinfrastructure and leadership for clinical and translational research at manysuch institutions.
Methods:
We surveyed CTSA hubs and received responses from 94% of them regarding the impact of the pandemic and the processes employed for the protection of research personnel and participants with respect to the conduct of research, specifically for studies unrelated to COVID-19.
Results:
In this report, we describe the results of the survey findings in the context of the current understanding of disease transmission and mitigation techniques.
Conclusions:
We reflect on common practices and provide recommendations regarding lessons learned that will be relevant to future pandemics, particularly with regards to staging the cessation and resumption of research activities with an aim to keep the workforce, research participants, and our communities safe in future pandemics.
Family education programs (FEPs) target caregiving-related psychological distress for carers of relatives/friends diagnosed with serious mental health conditions. While FEPs are efficacious in reducing distress, the mechanisms are not fully known. Peer group support and greater mental health knowledge are proposed to reduce carers' psychological distress by reducing stigmatising attitudes and self-blame, and strengthening carers' relationship with their relative.
Methods
Adult carers (n = 1016) who participated in Wellways Australia's FEP from 2009 to 2016 completed self-report questionnaires at the core program's start and end, during the consolidation period, and at a 6-month follow-up. Those who enrolled early completed questionnaires prior to a wait-list period. We used linear mixed-effects modelling to assess the program's effectiveness using a naturalistic wait-list control longitudinal design, and multivariate latent growth modelling to test a theory-based process change model.
Results
While there was no significant change over the wait-list period, psychological distress, self-blame and stigmatising attitudes significantly decreased, and communication and relationship quality/feelings increased from the core program's start to its end. Changes were maintained throughout the consolidation period and follow-up. Peer group support significantly predicted the declining trajectory of distress. Peer group support and greater knowledge significantly predicted declining levels of self-blame and stigmatising attitudes, and increasing levels of communication.
Conclusions
This is the first study to quantitatively validate the mechanisms underlying the effect of FEPs on carers' psychological distress. Peer group support is key in modifying carers' appraisals of their friend/relatives' condition. Continued implementation of FEPs within mental health service systems is warranted.
This paper outlines a theoretical approach to speech sound systems based on the notion of phonological potentials: physical ‘pressures’ or biases that give rise to discrete structure and the tendencies associated with this structure that arise from the physical nature of speech sound systems. We apply this approach to a poorly understood area of phonology – phenomena of the lower vocal tract (LVT) – through a schematic that encapsulates the complex interactions among the vocal tract structures responsible for producing LVT sounds. With the framework, we provide an account of a range of LVT phenomena from several languages, illustrating how tonal, phonatory, and vowel qualities interact. Finally, we consider how the idea of phonological potentials extends across various physical domains and might exhibit patterns of alignment across these domains, thereby serving to guide the formation of patterns found in speech sound systems.
Involuntary admission can be traumatic and is associated with negative attitudes that persist after the episode of illness has abated.
Aims
We aimed to prospectively assess satisfaction with care at the points of involuntary admission and symptomatic recovery, and identify their sociodemographic, clinical and service experience predictors.
Method
Levels of satisfaction with care, and clinical and sociodemographic variables were obtained from a representative cohort of 263 patients at the point of involuntary admission and from 155 of these patients 3 months after termination of the involuntary admission. Data were analysed with multiple linear regression modelling.
Results
Higher baseline awareness of illness (B = 0.19, P < 0.001) and older age (B = 0.05, P = 0.001) were associated with more satisfaction with care at baseline and follow-up. Transition to greater satisfaction with care was associated with improvements in awareness of illness (B = 0.13, P < 0.001) and in symptoms (B = 0.05, P = 0.02), as well as older age (B = 0.04, P = 0.01). Objective coercive experiences were not associated with variation in satisfaction with care.
Conclusions
There is wide variation in satisfaction with coercive care. Greater satisfaction with care is positively associated with clinical variables such as increased awareness of illness.
Terrestrial meteorite ages indicate that some ice at the Allan Hills blue ice area (AH BIA) may be as old as 2.2 Ma. As such, ice from the AH BIA could potentially be used to extend the ice core record of paleoclimate beyond 800 ka. We collected samples from 5 to 10 cm depth along a 5 km transect through the main icefield and drilled a 225 m ice core (S27) at the midpoint of the transect to develop the climate archive of the AH BIA. Stable water isotope measurements (δD) of the surface chips and of ice core S27 yield comparable signals, indicating that the climate record has not been significantly altered in the surface ice. Measurements of 40Aratm and δ18Oatm taken from ice core S27 and eight additional shallow ice cores constrain the age of the ice to approximately 90–250 ka. Our findings provide a framework around which future investigations of potentially older ice in the AH BIA could be based.
Windpumping has been identified as a process that could potentially enhance sublimation of surface snow at high forcing frequency and spawn air movement deeper in firn at lower frequencies. We performed an experiment to examine the relationship between high-frequency wind and pressure measurements within the top meter of an alpine snowpack and compared experimental results with two theoretical predictions. We find that both theoretical predictions underestimate high-frequency perturbation pressure attenuation with depth in the near-surface snowpack and the discrepancy between theory and measurement increases with perturbation pressure frequency. The impact of this result for near-surface snow is that potential enhanced sublimation will occur over a shallower snow depth than these two theories predict. Correspondingly, interstitial air mixing at depth in firn will be driven by lower frequencies than these two theories predict. While direct measurement of these energy-rich lower frequencies is beyond the scope of this paper, stationary pressure measurements validate the presence of a pressure field that could drive near-surface circulation.
Hydrocephalus is caused by different etiological factors, but the common final pathway creates a vicious circle of altered cerebrospinal fluid (CSF) circulation, cerebral blood flow, and metabolism that affects brain homeostasis. In communicating hydrocephalus, draining of CSF appears to be the simplest way of interrupting this circle by improving the CSF circulation. The mathematical model of CSF pressure volume compensation provides a theoretical basis for the differential diagnosis of hydrocephalus. Eighteen nonprogrammable and eight programmable valves reveal the common hydrodynamic properties of contemporary shunts. Any repetitive variations of proximal pressure have a tendency to decrease the nominal operating pressure of shunts with unidirectional valves. Shunt operating pressure is the value of intracranial pressure (ICP) that should be fixed when the opened shunt is draining CSF with the rate equal to that of its production. It is slightly higher than shunt opening pressure.
British culture today is the product of a shifting combination of tradition and experimentation, national identity and regional and ethnic diversity. These distinctive tensions are expressed in a range of cultural arenas, such as art, sport, journalism, fashion, education, and race. This Companion addresses these and other major aspects of British culture, and offers a sophisticated understanding of what it means to study and think about the diverse cultural landscapes of contemporary Britain. Each contributor looks at the language through which culture is formed and expressed, the political and institutional trends that shape culture, and at the role of culture in daily life. This interesting and informative account of modern British culture embraces controversy and debate, and never loses sight of the fact that Britain and Britishness must always be understood in relation to the increasingly international context of globalisation.
What does it mean for us to study a national culture? As we will see in the pages to come, it means looking across and reflecting upon a range of the practices and activities that contribute towards the shared experience of community and 'nation'. In part our endeavour calls upon an understanding of the various cultural and political institutions within which culture is organised and regulated, but, perhaps even more, it demands we comprehend something of the transience and excitement of everyday experience. In Britain, cultural activities are shaped by their histories and their traditions, but they also have a dynamic relationship with the present. A comprehensive account of British culture should therefore be alert to the forces that give living, thinking and playing in Britain form and character, while presenting an enthusiastic account of how this national culture changes along with the population and the world at large.
The Cambridge Companion to Modern British Culture offers just such an introduction to culture in twenty-first-century Britain. It brings together seventeen critical and insightful essays by some of the leading academics in British intellectual life. The subjects and issues the chapters cover are purposively varied, reflecting the diversity and debates that circulate in discussions of modern British culture. What emerges is a dynamic collection that brings together a number of aspects of living in and thinking about British culture. This is, therefore, a Companion designed to provide a fascinating and informative overview of modern British culture. However, the reader will also learn that British culture is not singular. Like most modern national cultures it is characterised by diversity and difference.
