The diagnosis of CHD not only affects the patient but also their entire environment, including parents, causing significant alterations in their mental health. This study was to assess the levels of anxiety and depression in parents of children with CHD at different stages of the disease.
Methods:
The PMNCC and PMNCR questionnaires were administered to parents of children with CHD to measure levels of state anxiety (STAI-E) and trait anxiety (STAI-R).
Results:
A total of 459 questionnaires were administered. For the state anxiety questionnaire (STAI-E), the mean score was 36, with high anxiety levels observed in 81.3% of participants and above-average levels in 18.7%. Regarding the severity of state anxiety, 82.6% presented severe anxiety, followed by moderate anxiety in 17.2%. For the trait anxiety questionnaire (STAI-R), the mean score was 43, with high levels observed in 91.5% of participants and above-average levels in 7.2%. Severe anxiety predominated in 96.7% of cases.
Conclusions:
The mental health of parents of children with CHD is often neither diagnosed nor adequately addressed in a timely manner by paediatric cardiology teams. Assessment and support from a multidisciplinary team are required for the early identification of these conditions.
Point-of-care technology (POCT) has expanded rapidly, particularly since the COVID-19 pandemic. However, less is known about which POCT applications and features patients and caregivers prioritize for lung disease management.
Methods:
We refined a patient-facing survey based on feedback from an online focus group recruited through community and advocacy volunteer networks. The survey was then administered via ResearchMatch to uncompensated U.S. volunteers, who indicated interest in lung disease research (April 1 to May 14, 2025; 6,333 invitations). POCT perceptions were measured via a 10-point Likert scale.
Results:
We received 214 responses (3.4% response rate). Respondents were predominantly patients (79%), female (71%), and older than 60 years (59%). Mean ratings suggested strong perceived benefits across nine POCT benefits and low concern across most drawbacks. The greatest concern was insurance coverage for POCT-associated costs (mean score: 6.7/10). Obstructive lung conditions were most frequently prioritized for future POCT applications.
Conclusion:
Among a national sample of ResearchMatch volunteers affected by lung disease, interest in POCT was high, and insurance coverage remained the most salient concern. By describing preferences and concerns of patients, this study informs future design, regulatory approval, and clinical integration. These findings provide evidence for POCT developers, clinicians, and policymakers focused on improving patient-centered care.
In a community mental health setting, we studied real-world relapse rates in patients with a history of psychosis, before and after switching from oral antipsychotics to a long-acting injectable antipsychotic (LAIA). We also aimed to evaluate the relevance of metabolic/demographic factors in relapse rate.
Methods:
Twenty-five individuals with a past history of psychosis and variable medication concordance who were switched from oral antipsychotics to LAIAs were included in the study. Oral agents were converted to olanzapine equivalents whilst LAIA generics were converted to flupenthixol depot equivalents. The depot equivalent oral dose of olanzapine was calculated, assuming an oral bioavailability of 40%. Relapse-rates occurring over the time periods on oral therapy were compared with rates occurring following initiation of LAIAs. Relapse was defined as any psychiatric hospital admission.
A multivariable Poisson regression model including drug formulation/age/sex/smoking status/BMI were fitted with follow-up time as an offset to estimate adjusted incidence rate ratios and associations with relapse outcomes.
Results:
The mean±SD age of the 25 individuals was 50.6±13.9 years whilst 12 (60%) were male. Mean BMI of males/females was 28.1±9.3 kg/m2/ 32±6.4 kg/m2(higher in women) respectively. 65% of patients received either flupenthixol or zuclopenthixol depot with next most common depot being Risperidal Consta. The median (IQR) of daily oral olanzapine equivalent was 10mg (6.9 – 20.0mg)/day and after switching to depot was 16.0mg (5.4 – 40.7mg)/day. The 4-week depot equivalent dose for services users switched to depot was flupenthixol 480mg (200 – 1220mg) / 4-weeks.
Following adjustment for age/sex/smoking status/BMI, relapse rates were significantly lower during LAIA treatment compared with oral treatment (incidence rate ratio [IRR] 0.13, 95% CI 0.08–0.22, p<0.001). Thus depot antipsychotics were associated with an 87% reduction in relapse rates compared to oral therapy. Male sex/younger age/lower BMI were independently associated with higher relapse rates (Exp (beta) 1.9/0.98/0.94 respectively (p<0.05)).
Conclusion:
In this real-world community mental health setting, this study highlights that depot antipsychotics provide a dramatic and sustained reduction of 87% in relapse rate for individuals with a history of psychosis. These findings support early prescription of LAIAs in prevention of psychosis relapse. Further evaluation is warranted to elucidate the potential of LAIAs as a treatment option after first presentation of psychosis.

Olanzapine long-acting injection (OLAI) is prescribed as maintenance antipsychotic treatment within small established clinics in Southwark and Lambeth. Despite the association between long-acting antipsychotics use and reductions in the number of relapses and hospital admissions, and oral olanzapine being the most commonly prescribed antipsychotic, OLAI is the least commonly prescribed LAI. This is due to staff, space and funding resources needed for post-injection monitoring, a requirement unique to OLAI. In order to provide equitable access to evidence-based treatments like OLAI within the Trust, provision of OLAI must be expanded. This observational, non-interventional, retrospective study aims to measure a range of relevant outcomes in order to demonstrate the achievement of good treatment value.
Methods:
25 patients were initiated on OLAI between January 2020 and January 2022 and were followed up for 2 years. Our main outcome measures are: continuation rates of OLAI over the 2 year follow-up period, and reasons for stopping, relapse rates (number of bed days and hospital admissions) 2 years before and after starting OLAI, adherence to physical health and side-effect monitoring, and physical health outcomes. A retrospective review of general clinical patient notes and OLAI clinic notes was conducted.
Results:
Out of the 21 patients included in analysis, the 2 year continuation rate was 42.9% (n=9). Within these 9 patients, there was a notable reduction in the mean number of bed days, and zero admissions during the 2 year follow-up period. The most common reasons for discontinuation were adverse effects, main one being weight gain, followed by post-injection monitoring. Physical health monitoring during the 2 year follow-up period was inconsistent, this may partly be due to the Covid-19 pandemic. Weight was most consistently measured, however blood test measures were done less frequently, and declined over time. For the 9 patients who were followed up for 2 years, weight increased by a mean of 7.42kg.
Conclusion:
Whilst OLAI appears to have a very positive effect on the rate of relapse, especially with the reduction of admissions to zero, adverse effects and post-injection monitoring requirements may discourage patients from continuing. Next steps include embedding processes to ensure all physical health parameters are monitored, consider preventative measures against common adverse effects, and activities to improve acceptability of post-injection monitoring. By doing so, we can continue to promote patient safety as OLAI provision expands within the Trust.

Many guidelines recommend deprescribing benzodiazepines and z-drugs in most long-term users. Due to physical dependence in those using medication as prescribed (distinct from addiction), discontinuation can be difficult and is often unsuccessful, as withdrawal symptoms can be severe and long-lasting, especially after long-term use. There is a lack of clarity on how to taper patients in a tolerable manner that minimizes discomfort. Current guidelines vary with some suggesting linear reductions (e.g. 1 mg every 1–4 weeks) and some proportionate reductions (e.g. 5%–10% of the most recent dose per month, with smaller reductions as the dose decreases). The shape of the relationship between dose of benzodiazepine and activity at gamma-aminobutyric acid-A (GABA-A) receptors is hyperbolic: steeply inclining at low doses, flattening at higher doses. Consequently, linear dose reductions produce increasingly large changes in receptor occupancy, predicting escalating withdrawal effects, while hyperbolic or proportionate dose reductions produce linear reductions in pharmacological effect. Slower tapering (over months and years) may be more successful than tapering over days or weeks. In practice, rate of tapering should be adjusted according to severity of withdrawal effects. Final doses for some people will need to be very small (equivalent to as little as 0.2 mg of diazepam, or less) so that the last ‘step down’ to zero is not larger than prior tolerated reductions in terms of pharmacological effects. Liquids or compounded formulations of medication can be helpful at low doses to make small reductions. Guidelines should recommend hyperbolic tapering while awaiting randomized trials comparing linear with hyperbolic tapering.
Clozapine is the only effective treatment for treatment-resistant schizophrenia, but concerns over blood dyscrasia and need for monitoring limit its use. Evidence suggests many hematological abnormalities may result from surveillance bias, with agranulocytosis being the primary adverse effect directly induced by clozapine. This systematic review (PROSPERO: CRD42024487199) investigates non-genetic risk factors associated with blood dyscrasia during clozapine treatment, focusing on neutropenia and agranulocytosis. Random-effect meta-analyses were performed on studies reporting quantitative risk data. Due to inconsistent neutropenia definitions, analyses used absolute neutrophil count (ANC) thresholds of <2000/mm3, <1500/mm3, and <500/mm3. Forty-four studies were included in the systematic review, 15 in meta-analyses. No significant association was found between agranulocytosis and female gender (OR = 1.48, 95% CI: 0.92–2.38; p = 0.106) or age (pooled standardized mean difference [SMD] = 0.32, 95% CI: –0.26 to 0.90, p = 0.285), whilst a modest inverse association with clozapine dose (SMD = –0.32, 95%CI: –0.50 to –0.14, p < 0.001) and baseline white cell count (SMD = –0.21, 95%CI: –0.40 to –0.03, p = 0.026) was found. Neutropenia (ANC < 2000/mm3) was positively associated with concomitant psychotropic use (OR = 2.15, 95% CI: 1.13–4.07, p = 0.019). Clozapine rechallenge studies revealed no significant associations with gender, age, duration of initial clozapine trial, or length of discontinuation period prior to rechallenge. No strong predictors of clozapine-associated blood dyscrasia were identified. Findings may be limited by study variability, surveillance bias, and lack of consistent differentiation between agranulocytosis and milder neutropenia, highlighting limitations in current evidence.
Antimicrobial stewardship programs (ASPs) are designed to optimize antimicrobial use for healthcare facilities and are required at all acute care and critical access hospitals (CAHs). However, rural CAHs often lack the resources to implement robust ASPs. The purpose of this study was to evaluate the impact of adding regional remote antimicrobial stewardship services across a 14-hospital system consisting of one acute care and thirteen CAHs.
Methods:
Remote ASP expansion consisted of adding an infectious disease (ID) pharmacist and two ID physicians (0.3 FTE) to provide daily stewardship activities including prospective feedback on antibiotic optimization and use education through remote chart review and communication. Antimicrobial utilization, cost savings, and Clostridioides difficile infection (CDI) rates were tracked. Intervention data and acceptance rates were also collected.
Results:
In the first twelve months following regional remote stewardship expansion, the ASP demonstrated a $619,053.97 reduction (56% decrease in Antibiotic Cost/CMI adjusted patient days) in antimicrobial expenses. While only aztreonam use was significantly reduced at the acute care facility (P < .01), the use of vancomycin, meropenem, linezolid, and aztreonam decreased by 33%, 31%, 18%, and 35%, respectively, among the CAHs (P < .001). A 53% reduction in CDI rates was observed across the health system (P < .01). The program averaged 92 interventions per month, with an overall intervention acceptance rate of 86%.
Conclusions:
Remote ASPs represent a viable strategy for extending antibiotic stewardship expertise to resource-limited settings to achieve financial and clinical benefits.
Grazing impacts on soil organic carbon (SOC) are vexingly difficult to predict due to intricate interactions among site-specific weather, vegetation and specified grazing treatments. This longitudinal study capitalizes on a multi-decadal grazing experiment in the semiarid northern mixed-grass prairie of the North American Great Plains with grazing treatments of season-long light and heavy stocking rates, and exclosures (non-grazed) established in 1982 and soils sampled in 1993, 2003 and 2013. Increasing grazing intensity from non-grazed to heavy grazed reduced annual aboveground standing crop biomass and shifted the plant community dominance from cool-season (C3) to warm-season (C4) perennial grasses. Concentrations of SOC and soil nitrogen (N) decreased from 1993 to 2013 for the 0-5, 5-15 and 15-30 cm depths for all grazing treatments, but grazing intensity did not affect SOC and N with the exception of greater N concentrations observed in the 0-5 cm depth with season-long light grazing. Annual precipitation decreased 4.2 mm yr-1 from 1982 to 2013; conversely, mean annual maximum and minimum temperatures did not change. Observed directional trends in precipitation may likely impact ecosystem functioning for soil SOC and N concentrations more than grazing-induced changes in plant communities and aboveground production in this semiarid rangeland resulting in reducing expectations of increased SOC and N with livestock grazing in semiarid rangeland ecosystems of the North American Great Plains.
Patients undergoing craniotomy experience a higher risk of seizures in the ensuing months. Consensus is lacking regarding the appropriate timeframe for safe return to driving following craniotomy in patients not otherwise limited by neurological deficits or a history of epilepsy.
Methods:
The Canadian Neurosurgery Research Collaborative (CNRC) distributed an anonymous, voluntary, electronic cross-sectional survey via SurveyMonkey to Canadian neurosurgeons. The survey comprised 16 questions designed to assess practice variations regarding recommendations for return to driving following craniotomy, stratified according to pathological diagnosis.
Results:
Forty-eight Canadian neurosurgeons responded to the survey. Driving recommendations varied greatly, with most surgeons recommending return to driving within one month of the craniotomy. The rationale behind these restrictions varied widely, consistent with the lack of evidence-based data to guide decision-making.
Conclusion:
This study emphasizes the lack of standardized practices regarding return to driving recommendations for patients undergoing craniotomy without prior seizures. Development of national return to driving guidelines would assist Canadian clinicians in making informed decisions regarding the optimal timeframe for the safe return to driving.
Food systems sustainability has interested researchers for decades; one area of interest is developing methods to measure it in various contexts. Our review of the literature finds many studies that have posited metrics and indicators for measuring sustainability in the food system, with most of them relying on secondary data rather than direct inquiry of stakeholders like farmers. This Preliminary Report presents results of farmer perceptions of sustainability, focusing on consumer-facing agriculture (direct market and agritourism) farms in Vermont, as part of the first phase of research in one of a set of projects aimed at developing sustainability metrics. We emphasize metrics that can be used for farm management, marketing, and policy advocacy, and add two dimensions (human and production) to the more common three (ecological, economic, and social). Using interviews from six case studies, we posit indicators across five dimensions of sustainability and identify tradeoffs in achieving them, emphasizing the farmers’ experiences. Our discussion compares and contrasts our results with the literature. Results will form the basis of a statewide farmer survey, which will be conducted in the next year.
To develop an approach for creating facility-specific urinary antibiograms accounting for the low number of isolates recovered in nursing homes (NHs).
Design:
Retrospective analysis of urine culture data collected in NHs in five states.
Setting:
Data on 5097 urine culture isolates collected across 59 study NHs from January 1, 2020 to December 31, 2021. Four consulting microbiology laboratories served the study homes.
Methods:
We compared a Clinical and Laboratory Standards Institute (CLSI) standard antibiogram model to four weighted-incidence syndromic antibiogram (WISCA) models utilizing alternate formatting rules. Ability to produce a facility-specific antibiogram with at least 30 isolates and the impact on susceptibility predictions were compared.
Results:
Only one facility could generate a CLSI standard antibiogram for the three most commonly recovered Gram-negative isolates over a one-year period. Ability to generate an antibiogram increased with each of the four WISCA models trialed (36%, 54%, 85%, 85%) with the most successful models combining all Gram-negative isolates over a two-year period. Shortening the definition of duplicate isolates from 12 to 3 months did not improve performance. Using all Gram-negative isolates, rather than the three most recovered pathogens, resulted in meaningful changes in the predicted activity of ampicillin-sulbactam, cefazolin, ceftriaxone, and trimethoprim-sulfamethoxazole in several study NHs.
Conclusions:
These results suggest that WISCAs using 2-years of urinary culture data including all gram-negative isolates and excluding duplicate isolates within twelve months maximizes the number of NHs able to create a valid antibiogram.
Urban–rural divides are large and growing in many national elections, but the sources of this widening divide are not well understood. Recent research has pointed to policy disagreement as one possible mechanism for this growing divide; if urban and rural residents hold increasingly dissimilar policy preferences, this disagreement could produce ever‐widening urban–rural electoral divides. We investigate this possibility by creating a synthesized dataset of nearly 1000 policy issue questions across 10 distinct Canadian national election studies conducted between 1993 and 2021 (N = 5.3 million), combined with a measure of the urban or rural character of every federal electoral district. This dataset allows us to measure urban–rural policy disagreement across a much larger range of policy issues and over a much longer time period than has previously been possible. We find strong evidence of urban–rural policy disagreement across a range of issues, and especially in areas of cultural policy, including questions relating to gun control, immigration and Indigenous affairs. We further find strong support for the ‘progressive cities’ hypothesis; in nearly all policy domains, urban residents support more left‐wing positions on policy issues than rural residents. However, we find no evidence these urban–rural policy divides have grown since the 1990s. Urban–rural policy disagreement, while large and meaningful, cannot explain the ever‐widening urban–rural political divide.
While some 40 per cent of the students undertaking political science degrees in the UK are women, about three-quarters of those teaching them are men. This article examines why female undergraduates are less likely to go into graduate work in politics, utilising focus groups conducted with groups of male and female students and interviews with the female students in four large UK universities. The research identifies eight key factors that impacted upon our respondents' decisions to undertake further study. The first four affected both men and women, although there were subtle, yet important, differences in how the women spoke about these issues, and can be somewhat loosely categorised as: money; making a difference; lack of information; and self-confidence. The other four factors influenced the women's, but not the men's, views about graduate work and the profession: stereotyping; role models; family commitments, and time constraints. On the basis of our research, we suggest how national political science associations and individual departments might increase the number of women undertaking graduate work.
This chapter offers an overview of Antarctica’s major meteorological and climate features using the latest methods, data products, and research findings. The first half of the chapter presents a thorough description of the Antarctic geography and its climatological temperature, precipitation, and near-surface environment. It provides a dedicated section covering Antarctic foehn and foehn-induced warming, which have been identified as major ‘hot spots’ for Antarctic surface melt and ice shelf destabilisation. Next the chapter details the major large-scale and regional atmospheric circulation patterns that characterise the high southern latitudes and strongly influence Antarctic meteorology, including the Southern Annular Mode, teleconnections associated with the El Niño Southern Oscillation, and the Amundsen Sea Low. We then present the latest research discoveries on Antarctic climate extremes, with a focus on Antarctic ‘atmospheric rivers’ and their role in driving extreme temperature, precipitation, and surface melt events. The chapter closes with a summary of recent Antarctic climate change, current research gaps and challenges, and recommendations for future work.
Clozapine is licensed for treatment-resistant schizophrenia (TRS). Because of the risk of clozapine-induced agranulocytosis, its use requires regular haematological monitoring. Substantive evidence supports revisions of absolute neutrophil counts (ANCs) for clozapine discontinuation and ceasing of indefinite haematological monitoring.
Aims
To examine the cost-effectiveness and budget impact of different haematological monitoring schemes compared with the current UK monitoring practice for patients using clozapine.
Method
We performed a cost-effectiveness and budget impact analysis from the healthcare system perspective over a 3-year period, comparing the current UK clozapine monitoring practice with extended haematological monitoring and a revision of ANC criteria. Costs and quality-adjusted life years (QALYs) were estimated using a semi-Markov model that followed a simulated cohort of 100 000 adults with TRS. Sensitivity analyses were conducted.
Results
Extended haematological monitoring would lead to lower mean total costs per patient (6388.34 v. 5569.77 GBP) and not compromise quality of life (in QALYs 795.83 v. 795.79 days). A revision of ANC criteria for clozapine discontinuation would not substantially lower costs (6388.34 v. 6390 GBP), but lead to a slight increase in QALYs (795.83 v. 797.08 days), through patients benefitting from longer clozapine treatment. A combination of extended haematological monitoring and revision of ANC criteria would be the dominant strategy, which means that costs are lower (6388.34 v. 5548.50 GBP) and QALYs slightly increase (795.83 v. 797.03 days) compared with the current UK monitoring practice.
Conclusions
A revision of current UK clozapine monitoring practice would be beneficial from both a clinical and an economic perspective. Adjusting ANC criteria for clozapine cessation avoids unnecessary early discontinuation of clozapine treatment and has a positive impact on quality of life. An extension of monitoring intervals reduces costs borne by the healthcare system. Safety is not compromised by these changes.
One of the most incredible aspects of the Mexican Baja Peninsula is the immense wealth of plant and animal diversity it holds. The human communities living alongside this richness have boundless intimate knowledge of its natural history, potentially with novel insights into the ecological and evolutionary processes shaping the diversity of plants and animals. These same human communities have likely also witnessed changes to these natural environments over their lifetimes, particularly as the effects of global change are being felt by similar rural communities around the world. However, because the area is so remote, they often have little access to scientific data or current information about the causes or effects of the changes they observe. Using a thematic analysis of recorded conversations, this project seeks to connect remote rural ranches in Mexico with scientists, to gather data on the issues that matter most to the community members, and work to find collaborative solutions. Through thematic analysis of recorded conversations, our research reveals that unpredictable climate variability, including droughts, hurricanes, and shifting seasonal patterns, poses significant challenges to ranching livelihoods. Ranchers’ deep ecological knowledge provides critical insights into the stresses of changing and increasingly unpredictable environmental trends. By integrating local perspectives with scientific approaches, this study highlights the potential for collaborative biodiversity research.
The Hector Galaxy Survey is a new optical integral field spectroscopy (IFS) survey currently using the Anglo-Australian Telescope to observe up to 15 000 galaxies at low redshift ($z \lt 0.1$). The Hector instrument employs 21 optical fibre bundles feeding into two double-beam spectrographs, AAOmega and the new Spector spectrograph, to enable wide-field multi-object IFS observations of galaxies. To efficiently process the survey data, we adopt the data reduction pipeline developed for the SAMI Galaxy Survey, with significant updates to accommodate Hector’s dual-spectrograph system. These enhancements address key differences in spectral resolution and other instrumental characteristics relative to SAMI and are specifically optimised for Hector’s unique configuration. We introduce a two-dimensional arc fitting approach that reduces the root-mean-square (RMS) velocity scatter by a factor of 1.2–3.4 compared to fitting arc lines independently for each fibre. The pipeline also incorporates detailed modelling of chromatic optical distortion in the wide-field corrector, to account for wavelength-dependent spatial shifts across the focal plane. We assess data quality through a series of validation tests, including wavelength solution accuracy (1.2–2.7 km s$^{-1}$ RMS), spectral resolution (FWHM of 1.2–1.4 Å for Spector), throughput characterisation, astrometric precision ($\lesssim$ 0.03 arcsec median offset), sky subtraction residuals (1–1.6% median continuum residual), and flux calibration stability (4% systematic offset when compared to Legacy Survey fluxes). We demonstrate that Hector delivers high-fidelity, science-ready datasets, supporting robust measurements of galaxy kinematics, stellar populations, and emission-line properties and provide examples. Additionally, we address systematic uncertainties identified during the data processing and propose future improvements to enhance the precision and reliability of upcoming data releases. This work establishes a robust data reduction framework for Hector, delivering high-quality data products that support a broad range of extragalactic studies.
Clozapine remains underused despite its unparalleled efficacy in treatment-refractory schizophrenia. One of the reasons for its underuse is the fear of severe neutropenia and its consequences.
Aims
To scrutinise the association between severe neutropenia and clozapine in a cohort of patients clinically diagnosed with clozapine-induced severe neutropenia.
Method
We used data from the South London and Maudsley National Health Service Foundation Trust’s anonymised case register, known as the Clinical Record Interactive Search. We extracted details of cases where clozapine use was associated with two consecutive neutrophil counts below 1.5 × 109/L. A panel of clinicians independently assessed each case. Agreement was reached on which cases clozapine was the likely or definite cause of the severe neutropenia, the risk to life and whether or not rechallenge with clozapine could be attempted.
Results
There were 96 cases where two consecutive neutrophil counts below 1.5 × 109/L were registered. The panel judged that 9 (9.4%) were definitely caused by clozapine and a further 11 (11.5%) were probably caused by clozapine. Overall, 18 (18.8%) patients should be precluded from ever receiving clozapine again according to the panel (all from the 20 cases where clozapine was the definite or probable cause). Of the remaining 76 cases of severe neutropenia the cause could not be determined in 60 cases, but in 11 cases the cause was benign ethnic neutropenia, in 2 others the cause was cancer chemotherapy, in 2 it was infections and in 1 it was laboratory error. In almost 80% of cases, clozapine was not the clear cause of the neutropenia observed.
Conclusions
The large majority of severe neutropenia episodes mandating cessation of clozapine may not be caused by clozapine. Threshold-based monitoring systems cause unnecessary stopping of clozapine because they lack the necessary specificity for clozapine-related blood disorders.
The organic-rich shales and mudstones composing the Miaolingian (‘middle’ Cambrian) through Tremadocian (Lower Ordovician) Alum Shale Formation have been extensively mined for production of alum at Andrarum in southeastern Scania (Skåne), southern Sweden. Here, the formation was exploited between 1637 and 1912, and a brief account is given of the history of the exploitation. The alum industry had its heyday in the mid-1700s when it was owned by Christina Piper (1673–1752). During this time some 900 people lived within the working area, and it had its own craftsmen, school, hospital and courthouse with a jail annex. The undeformed and virtually continuous succession at Andrarum is generally richly fossiliferous and, albeit largely covered by scree and vegetation, best exposed in the old quarries. The fossil faunas are dominated by trilobites and agnostoids, which form the basis for a detailed biostratigraphical framework. The history of geological and palaeontological research at Andrarum, since the pioneering works in the mid- to late 1800s, is reviewed. The sequence of strata was first elucidated by Alfred Gabriel Nathorst in 1869. Since then, the succession and its fossil content have been studied by a considerable number of influential researchers, such as Gustaf Linnarsson (1841–1881), Sven Axel Tullberg (1852–1886) and Anton H. Westergård (1880–1968). In the decades around the turn of the 21st century, Euan Clarkson initiated a number of projects focusing on the ontogeny, evolution and functional morphology of olenid trilobites from the Furongian at Andrarum, along with two important studies dealing with faunal dynamics and biotic turnovers. His research resulted in a series of pivotal papers on the geology and palaeontology of the Alum Shales.
Point-of-care technologies (POCTs) have grown increasingly prevalent in clinical and at-home settings, offering various rapid diagnostic capabilities. This study presents findings from a nationwide survey conducted between November 2023 and January 2024, capturing clinician perceptions of POCTs.
Methods:
The survey was distributed via email to healthcare professionals through academic and industry listservs and through LinkedIn posts. A total of 159 responses were analyzed.
Results:
Core priorities, including accuracy, ease of use, and availability, remain consistently valued over the years. However, several perceived benefits, including continuous patient monitoring, diagnostic certainty, and patient management exhibited significant declines in agreement compared to previous years. Despite this, clinician perceptions of POCTs’ abilities to enhance patient–provider communication remained stable. Evolving concerns may reflect heightened expectations and greater scrutiny as these technologies become commonplace. Agreement that POCTs may undermine clinical expertise increases, while concerns related to reimbursement and usability decline. Pilot questions related to artificial intelligence (AI) and machine learning (ML) indicated moderate openness to adopting AI-enhanced POCTs, particularly with tools offering novel clinical insights.
Conclusions:
While POCTs continue to be an asset in clinical settings, the findings of this study suggest a shift in provider attitudes toward a more neutral standpoint. Limitations include a low response rate, self-selection, and missing demographic data from a subset of participants. Future surveys will further integrate AI/ML-related questions while prioritizing broader demographic and geographic reach.
