AbstractAimTo develop evidence‐based clinical algorithms for the assessment and management of spontaneous, uncomplicated labour and vaginal birth.PopulationPregnant women at any stage of labour, with singleton, term pregnancies considered to be at low risk of developing complications.SettingHealth facilities in low‐ and middle‐income countries.Search StrategyWe searched for relevant published algorithms, guidelines, systematic reviews and primary research studies on Cochrane Library, PubMed, and Google on terms related to spontaneous, uncomplicated labour and childbirth up to 01 June 2023.Case scenariosThree case scenarios were developed to cover assessments and management for spontaneous, uncomplicated first, second and third stage of labour. The algorithms provide pathways for definition, assessments, diagnosis, and links to other algorithms in this series for management of complications.ConclusionsWe have developed three clinical algorithms to support evidence‐based decision making during spontaneous, uncomplicated labour and vaginal birth. These algorithms may help guide health care staff to institute respectful care, appropriate interventions where needed, and potentially reduce the unnecessary use of interventions during labour and childbirth.

AbstractAimsThe aim of this study is to identify cannabis products according to their appeal among young adults and measure product sales trends.Design, setting and participantsThis was a retrospective comparative study using point‐of‐sale data from licensed recreational cannabis retailers that include buyer age with birth year entered by retailers, set in California, USA. Cannabis purchases by young adults (aged 21–24, GenZ) were compared with older adults (age 25+) over 4 years (2018–21).MeasurementsSales for six cannabis product categories were analyzed using a commercial data set with imputations and a raw data set. Age‐appeal metrics were dollar and unit sales to young adults, and dollar and unit share ratios (young adults/older adults), where a share ratio of 100 denotes age‐appeal comparability. A product category was considered more young‐adult appealing than others if its mean on a metric was at least one standard deviation above the grand mean across all product categories.FindingsFlower (cannabis plant material) and vapor pen appealed to young adults based on absolute dollar sales, dominating young‐adult spending compared with other cannabis products (37.24 and 31.83%, respectively). Vapor pen and concentrate appealed to young adults based on dollar share ratios of 152, meaning these products comprised a 52% greater share of young‐adult cannabis spending relative to older‐adult spending (31.83/20.97% and 10.47/6.88%, respectively). Less appealing to young adults were pre‐roll, edible/beverage and absorbable products (tincture/sublingual, capsule and topical). Flower showed the largest dollar sales growth (B = +$3.50 million/month), next to vapor pen (B = +$1.55 million/month). Vapor pen tied for highest growth in the percent of product dollars from the largest package size (B = +0.85%/month) and showed the steepest price decline (B = −0.53 price per gram/month).ConclusionsIn California, USA, from 2018 to 2021, relative to older adults, young adults spent a greater share of their cannabis dollars on vapor pen and concentrate (products with high potency of delta‐9‐tetrahydrocannabinol).
Fish and macroinvertebrates respond differently to seasonal drying in tropical non‐perennial streams

Published: July 2024

AbstractSurface water drying challenges the persistence of lotic biological assemblages in non‐perennial streams and rivers. However, the effects of natural hydrological disturbances on an assemblage depend on individual species characteristics. In this study, we investigated the structure and association of fish and macroinvertebrate assemblages during two phases in non‐perennial streams (flowing vs. disconnected pools). We sampled fish and macroinvertebrate assemblages in five non‐perennial stream reaches located in the Caatinga (Brazilian semi‐arid region). Fish species were resistant to hydrological dynamics in the streams. On the other hand, some macroinvertebrate taxa from the flowing phase disappeared, and new taxa colonized the disconnected pools. The absence of lotic insects following flow cessation and the colonization of disconnected pools by lentic taxa facilitated macroinvertebrate assemblages persistence in these dynamic streams. Our study showed that fish and macroinvertebrate assemblages respond differently to the same natural flow cessation, which leads us to predict that flow changes will yield different assemblages, depending on the taxa. Thus, it is crucial to consider multi‐assemblage responses to effectively manage and conserve non‐perennial stream ecosystems in a tropical semi‐arid region.

AbstractIntroductionEvidence on the early life risk factors of adult CRS, and the history of asthma and allergies across the life course, is limited.AimTo investigate relationships between respiratory infective/allergic conditions in childhood, and asthma and allergies across the life course and CRS in middle age.MethodsData were from the population‐based Tasmanian Longitudinal Health Study (TAHS) cohort, first studied in 1968 when aged 6–7 years (n = 8583) and serially followed into middle age (n = 3609). Using a well‐accepted epidemiological definition, participants were assigned a CRS‐severity subtype at age 53: no sinusitis/CRS (reference); past doctor diagnosis only; current symptoms without doctor diagnosis; and doctor‐diagnosed CRS with current symptoms. Relationships with infective/allergic respiratory illnesses at age 7, and previously published asthma‐allergy trajectories from 7 to 53 years, were examined using multinominal regression.ResultsIn middle age, 5.8% reported current CRS symptoms with 2.5% doctor‐diagnosed. Childhood conditions associated with symptomatic doctor‐diagnosed CRS included frequent head colds (multinomial odds ratio [mOR] = 2.04 (95% confidence interval [95% CI]: 1.24, 3.37)), frequent tonsillitis (mOR = 1.61 [95% CI: 1.00, 2.59]) and current childhood asthma (mOR = 2.23 [95% CI: 1.25, 3.98]). Life course trajectories that featured late‐onset or persistent asthma and allergies were associated with all CRS subtypes in middle age; early‐onset persistent asthma and allergies (mOR = 6.74, 95% CI: 2.76, 16.4); late‐onset asthma allergies (mOR = 15.9, 95% CI: 8.06, 31.4), and late‐onset hayfever (mOR = 3.02, 95% CI: 1.51, 6.06) were associated with symptomatic doctor‐diagnosed CRS.ConclusionCurrent asthma, frequent head colds and tonsillitis at age 7 could signal a susceptible child who is at higher risk for CRS in mid‐adult life and who might benefit from closer monitoring and/or proactive management. Concurrent asthma and allergies were strongly associated and are potential treatable traits of adult CRS.

SummaryBackgroundAlthough videolaryngoscopy has been proposed as a default technique for tracheal intubation in children, published evidence on universal videolaryngoscopy implementation programmes is scarce. We aimed to determine if universal, first‐choice videolaryngoscopy reduces the incidence of restricted glottic views and to determine the diagnostic performance of the Cormack and Lehane classification to discriminate between easy and difficult videolaryngoscopic tracheal intubations in children.MethodsWe conducted a prospective observational study within a structured universal videolaryngoscopy implementation programme. We used C‐MAC™ (Karl Storz, Tuttlingen, Germany) videolaryngoscopes in all anaesthetised children undergoing elective tracheal intubation for surgical procedures. The direct and videolaryngoscopic glottic views were classified using a six‐stage grading system.ResultsThere were 904 tracheal intubations in 809 children over a 16‐month period. First attempt and overall success occurred in 607 (67%) and 903 (> 99%) tracheal intubations, respectively. Difficult videolaryngoscopic tracheal intubation occurred in 47 (5%) and airway‐related adverse events in 42 (5%) tracheal intubations. Direct glottic view during laryngoscopy was restricted in 117 (13%) and the videolaryngoscopic view in 32 (4%) tracheal intubations (p < 0.001). Videolaryngoscopy improved the glottic view in 57/69 (83%) tracheal intubations where the vocal cords were only just visible, and in 44/48 (92%) where the vocal cords were not visible by direct view. The Cormack and Lehane classification discriminated poorly between easy and difficult videolaryngoscopic tracheal intubations with a mean area under the receiver operating characteristic curve of 0.68 (95%CI 0.59–0.78) for the videolaryngoscopic view compared with 0.80 (95%CI 0.73–0.87) for the direct glottic view during laryngoscopy (p = 0.005).ConclusionsUniversal, first‐choice videolaryngoscopy reduced substantially the incidence of restricted glottic views. The Cormack and Lehane classification was not a useful tool for grading videolaryngoscopic tracheal intubation in children.
Road Corridors as Real Estate Frontiers: The New Urban Geographies of Rentier Capitalism in Africa
Authors: Gillespie Tom , Mwau Baraka 
Published: July 2024

AbstractThis paper draws on research on infrastructure‐led development and urbanisation in Nairobi to explore the new urban geographies of rentier capitalism in Africa. Under the banner of Kenya's Vision 2030 national development strategy, Nairobi's agrarian hinterlands have been transformed by major road building projects. These initiatives have catalysed a peri‐urban property boom characterised by the conversion of agricultural and ranching land into urban real estate and the verticalisation of road corridors. The paper identifies four processes of land transformation driving this real estate market expansion: commodification; speculation; autoconstruction; and assetisation. Adopting a multi‐scalar conjunctural approach, it argues that rentier capitalism in this context is spatialised through the dramatic extension of real estate frontiers along the route of peri‐urban road corridors. Development along these corridors assumes a “grey” character that defies conventional formal–informal distinctions, enabling the extraction of large rentier profits and encouraging the further proliferation of frontier spaces.
Clinical and forensic aspects of potassium iodide: Suddenly in high demand across Europe due to fears of radiation poisoning from a nuclear attack in Ukraine
Authors: da Silva Lopes João Pedro , Barbosa Joana , Dinis‐Oliveira Ricardo Jorge 
Published: July 2024

AbstractPotassium iodide has demonstrated several therapeutic applications over time, being the choice for shielding the thyroid during radiation emergencies involving radioiodine release. Amidst the ongoing military conflict between Ukraine and Russia and the growing concern regarding the potential deployment of nuclear weapons, there has been a surge in the demand for potassium iodide across Europe. This work aimed to comprehensively review the current knowledge regarding the pharmacology, physiology, adverse effects, the protective role in reducing the risk of thyroid cancer and recommendations for potassium iodide use during radiation emergencies. Evidence on adverse effects is scarce, as potassium iodide is generally well‐tolerated. Guidelines for thyroid blocking with potassium iodide during radiation emergencies suggest that, among populations vulnerable to radioiodine exposure, the benefits of potassium iodide outweigh the risks of adverse effects. Controversial topics surrounding the utilization of potassium iodide in radiation emergencies include the prophylaxis in iodine‐deficient regions and following the detonation of dirty bombs, whether granule formulationsversustablets should be used and mental health concerns. Although the rise in demand seems to be a justified security measure, it is essential to recognize that potassium iodide protects the thyroid from radioiodine and does not impact the body's absorption of other radioactive materials or defend against external radiation exposure.
The ethics of overriding patient refusals during 5150s and other involuntary psychiatric holds
Authors: Quan Alexander 
Published: July 2024

AbstractInvoluntary psychiatric holds, such as the 5150 hold in California, allow for an individual to be taken into custody for evaluation and treatment for up to 72 h when they present a risk of danger to themselves. 5150s and other coerced holds present a bioethical tension as patient autonomy is overridden to provide psychiatric care. I discuss two arguments that aim to provide ethical justifications for overriding patient autonomy during 5150 holds: the “clinical benefit” and “lack of capacity” arguments. By demonstrating that these arguments do not always hold, I argue that overriding patient autonomy during 5150 holds is not always ethical and can be harmful. Lastly, I make recommendations for the 5150 and similar involuntary psychiatric holds to minimize harmful breaches of patient dignity: creating consistent field guidelines for assessing prehospital capacity, educating prehospital providers about the potential harms of 5150s, and utilizing existing support structures within the social context of the patient when they have capacity to refuse further prehospital care.
The effect of firm‐level economic policy uncertainty on labor share: Empirical evidence from China

Published: July 2024

AbstractIn the 21st century, various unexpected events such as the financial crisis and COVID‐19 have exacerbated the uncertainty of economic policies, whose influence, especially those at the firm level, on the labor share remains to be studied. This article constructs the firm‐level economic policy uncertainty (FEPU) through text analysis and empirically analyzes its impact on labor share. Empirical evidence suggests that FEPU can significantly decrease labor share, particularly among firms with financing constraints, low productivity, and high market shares. And the results hold up after a series of robustness tests. Moreover, mechanism analysis indicates that precautionary saving motives play a crucial role in driving firms’ reduction in labor share rather than capital substitution motives. Finally, we further find that although FEPU harms the labor share, it significantly reduces executive payment and has no significant effect on the payment of ordinary employees, thus reducing within‐firm inequality. This study enhances our comprehension of how economic policy uncertainty at the firm level affects firm behavior and provides theoretical and practical guidance for increasing labor share and employee welfare.

AbstractBackgroundBody mass index (BMI) serves as a global metric for assessing obesity and overall health status. However, the impact of BMI, treated as a continuous variable, on the risk of perioperative stroke remains poorly understood. This retrospective cohort study aimed to elucidate the association between BMI and the risk of perioperative ischemic stroke in patients undergoing non‐cardiovascular surgery.MethodsA cohort of 223,415 patients undergoing noncardiac surgery at the First Medical Center of Chinese PLA General Hospital between January 1, 2008 and August 31, 2019 was screened. Preoperative high BMI, defined as BMI >22.64 kg/m2, was the primary exposure, and the outcome of interest was the new diagnosis of perioperative ischemic stroke within 30 days post‐surgery. Robust controls for patient and intraoperative factors were implemented to minimize residual confounding. Logistic regression and propensity score matching were employed, and patients were stratified into subgroups for further investigation.ResultsThe overall incidence of perioperative ischemic stroke was 0.23% (n = 525) in the cohort. After adjusting for patient‐related variables (OR 1.283; 95% CI, 1.04–1.594; p < 0.05), surgery‐related variables (OR 1.484; 95% CI, 1.2–1.849; p < 0.001), and all confounding variables (OR 1.279; 95% CI, 1.025–1.607; p < 0.05), patients with BMI >22.64 kg/m2 exhibited a significantly increased risk of perioperative ischemic stroke. This association persisted in the propensity score matched cohort (OR 1.577; 95% CI, 1.203–2.073; p < 0.01). Subgroup analyses indicated that preoperative BMI >22.64 kg/m2 correlated with an elevated risk of perioperative ischemic stroke in female patients, those with coronary heart disease, peripheral vascular diseases, and individuals undergoing neurosurgery.ConclusionWe first identified BMI >22.64 kg/m2 as a substantial and independent risk factor for perioperative ischemic stroke in Chinese noncardiac surgery patients. Normal BMI may not suffice as a universal preventive standard. Instead, a more stringent perioperative weight management approach is recommended, particularly for specific subgroups such as female patients, those with coronary heart disease and peripheral vascular disease, and individuals scheduled for neurosurgery.
Incorporation of human–wildlife interactions in ecosystem‐based management to enhance conservation of endangered guitarfish

Published: July 2024

AbstractGrowing human use of the marine environment increases the proximity of humans to marine wildlife and thus likely increases human–wildlife interactions. Such interactions influence perceptions of nature and promote or undermine conservation. Despite their importance, human–wildlife interactions are rarely considered in ecosystem‐based marine spatial planning (MSP). Ideally, these interactions should be identified and considered in ecosystem‐based management (EBM), which is often purported to be the basis for MSP. We used Marxan software and data from a citizen science project documenting location, species, age, sex, and activity type to identify regions along Israel's coast with a high probability of encounters between people and 2 species of guitarfish. We considered the geographic distribution of these encounters and the various activities undertaken by the reporting observers. We ran 4 scenarios in Marxan. Two had conservation goals of 30% and 50% guitarfish habitat protection. In the third and fourth scenarios, we added a 50% conservation goal of human leisure activities to each guitarfish conservation goal. We also conducted a gap analysis between our guitarfish conservation goals and the Israel Nature and Parks Authority's master plan for marine protected areas. We found the park authority was close to meeting the 30% goal but was far from meeting the conservation goal of 50% of guitarfish habitat conservation. Different human uses were more likely to interact with different life stages of guitarfish, and different recreational activities occurred in different areas. Identifying areas of specific human use showed which activities should be addressed in conservation management decisions. Our addition of certain recreational uses to the model of habitat conservation showed how enhancing human dimensions in conservation planning can lead to more holistic ecosystem‐based conservation necessary for effective marine planning.

Published: July 2024

AbstractEpendymal and choroid plexus tumours arise in anatomically related regions. Their intraoperative differential diagnosis is large and depends on factors such as age, tumour site and clinical presentation. Squash cytology can provide valuable information in this context. Cytological features of conventional ependymomas, subependymomas and myxopapillary ependymomas as well as choroid plexus tumours are reviewed and illustrated. Differential diagnostic considerations integrating morphological and clinical information are discussed.

AbstractThe decline in global plant diversity has raised concerns about its implications for carbon fixation and global greenhouse gas emissions (GGE), including carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4). Therefore, we conducted a comprehensive meta‐analysis of 2103 paired observations, examining GGE, soil organic carbon (SOC) and plant carbon in plant mixtures and monocultures. Our findings indicate that plant mixtures decrease soil N2O emissions by 21.4% compared to monocultures. No significant differences occurred between mixtures and monocultures for soil CO2 emissions, CH4 emissions or CH4 uptake. Plant mixtures exhibit higher SOC and plant carbon storage than monocultures. After 10 years of vegetation development, a 40% reduction in species richness decreases SOC content and plant carbon storage by 12.3% and 58.7% respectively. These findings offer insights into the intricate connections between plant diversity, soil and plant carbon storage and GGE—a critical but previously unexamined aspect of biodiversity–ecosystem functioning.
