Noisy breathing is common at the end of life. Management of noisy breathing aims to reduce the noise via repositioning the person, suctioning the person's airways and using antimuscarinic drugs. Dying people are generally thought not to be distressed by noisy breathing at the end of life, but the noise may distress others. There is doubt on whether antimuscarinic drugs are any more effective than a placebo for noisy breathing. However, antimuscarinics are still commonly administered to people at the end of life.

To illuminate reasons behind decision making and noisy breathing at the end of life.

Semi-structured interviews and 'self-recorded brief accounts' with healthcare professionals.

Noisy breathing at the end of life is viewed as both a natural and a medical phenomenon. However, while most participants in the interviews thought that antimuscarinics were uneffective, the prescription and administration of antimuscarinics were embedded within professional culture.

Managing noisy breathing is a complex issue that incorporates natural and medical viewpoints and has a long-standing culture of practice. Research should aim to determine best practice and reduce a person's distress at the end of life.

Recently emphasis has been placed on the decarbonization of health care systems with National and World Health Organization initiatives aimed at carbon neutrality toward the mid-21st century. This study investigates greenhouse gas emissions related to telemedicine, its potential role in achieving carbon neutrality and its role in determining policy. We further investigate patient benefits related to telemedicine. Methods A systematic review was conducted of the PubMed, Medline, EMBASE, EMCARE, CINAHL, and HMIC databases. Eligibility of studies was determined by predefined criteria. Results A total of 31 studies were identified totaling over 57,000 patients. Carbon savings ranged from 0.69 kg CO2e (carbon dioxide equivalent) to 893 kg CO2e per encounter. Distances saved also ranged from 6.1 to 3,386 km. Further analysis of 18 included studies was conducted for cost savings that ranged from €1.73 in fuel costs to over U.S. $900 in travel related expenses. Similarly, 15 included studies were analyzed for time savings, which ranged from 38 min to 24 h. Conclusions There are substantial carbon savings to be made with telemedicine systems. Furthermore, there are substantial benefits to patients in terms of both time savings and cost savings. Rural and isolated communities or patients needing tertiary or quaternary care may be a particular cohort that might benefit disproportionally from telemedicine and is an area where the largest per capita emission savings can potentially be made.An electrochemical membrane reactor enables efficient hydrogen generation.Analysis of cancer genome sequences reveals new mutational signatures.Influential survey recommends $4.2 billion flagship mission to the ice giant Influential survey.Earlier maturation of Atlantic salmon is linked to indirect effects of fisheries on its prey.Flat optics has emerged as a key player in the area of structured light and its applications, owing to its subwavelength resolution, ease of integration, and compact footprint. Although its first generation has revolutionized conventional lenses and enabled anomalous refraction, new classes of meta-optics can now shape light and dark features of an optical field with an unprecedented level of complexity and multifunctionality. Here, we review these efforts with a focus on metasurfaces that use different properties of input light-angle of incidence and direction, polarization, phase distribution, wavelength, and nonlinear behavior-as optical knobs for tuning the output response. We discuss ongoing advances in this area as well as future challenges and prospects. These recent developments indicate that optically tunable flat optics is poised to advance adaptive camera systems, microscopes, holograms, and portable and wearable devices and may suggest new possibilities in optical communications and sensing.Still not fully prepared for living with the virus, the government is sticking to "zero COVID".Cross-electrophile coupling (XEC) reactions of aryl and alkyl electrophiles are appealing but limited to specific substrate classes. BLZ945 cell line Here, we report electroreductive XEC of previously incompatible electrophiles including tertiary alkyl bromides, aryl chlorides, and aryl/vinyl triflates. Reactions rely on the merger of an electrochemically active complex that selectively reacts with alkyl bromides through 1e- processes and an electrochemically inactive Ni0(phosphine) complex that selectively reacts with aryl electrophiles through 2e- processes. Accessing Ni0(phosphine) intermediates is critical to the strategy but is often challenging. We uncover a previously unknown pathway for electrochemically generating these key complexes at mild potentials through a choreographed series of ligand-exchange reactions. The mild methodology is applied to the alkylation of a range of substrates including natural products and pharmaceuticals.A science writer offers an accessible account of the Mesozoic's mass extinction.Further enhancing the performance and stability of inverted perovskite solar cells (PSCs) is crucial for their commercialization. We report that the functionalization of multication and halide perovskite interfaces with an organometallic compound, ferrocenyl-bis-thiophene-2-carboxylate (FcTc2), simultaneously enhanced the efficiency and stability of inverted PSCs. The resultant devices achieved a power conversion efficiency of 25.0% and maintained >98% of their initial efficiency after continuously operating at the maximum power point for 1500 hours under simulated AM1.5 illumination. Moreover, the FcTc2-functionalized devices passed the international standards for mature photovoltaics (IEC612152016) and have exhibited high stability under the damp heat test (85°C and 85% relative humidity).City lights lure migratory birds, with lethal results, but weather radar and modeling can help reduce the toll.As the world becomes increasingly dependent on satellites and other space technology, new participants from every global region are joining the "space club" to reap the benefits-expanding communication and navigation capabilities; guiding policies with Earth observations; developing economies through growth in space ventures; and deepening our understanding of the cosmos through exploration. Consequently, countries are focusing on job opportunities, competitiveness, national security, and on having a voice in the global governance of space activities. Africa not only has a growing interest in space, but African countries are realizing that there is strength in pooling their resources and efforts to grow the continent's outer space enterprise.Transposons become a focus of speculation and scrutiny in biomedical research.Shift focus from disarmament to preventing reemergence.Highlights from the Science family of journals.Highway fatalities increased in response to certain messages.Cytotoxic T lymphocytes (CTLs) and natural killer cells kill virus-infected and tumor cells through the polarized release of perforin and granzymes. Perforin is a pore-forming toxin that creates a lesion in the plasma membrane of the target cell through which granzymes enter the cytosol and initiate apoptosis. Endosomal sorting complexes required for transport (ESCRT) proteins are involved in the repair of small membrane wounds. We found that ESCRT proteins were precisely recruited in target cells to sites of CTL engagement immediately after perforin release. Inhibition of ESCRT machinery in cancer-derived cells enhanced their susceptibility to CTL-mediated killing. Thus, repair of perforin pores by ESCRT machinery limits granzyme entry into the cytosol, potentially enabling target cells to resist cytolytic attack.Removing membrane pores may help cancer cells survive T cell assault.Natural molecular machines contain protein components that undergo motion relative to each other. Designing such mechanically constrained nanoscale protein architectures with internal degrees of freedom is an outstanding challenge for computational protein design. Here we explore the de novo construction of protein machinery from designed axle and rotor components with internal cyclic or dihedral symmetry. We find that the axle-rotor systems assemble in vitro and in vivo as designed. Using cryo-electron microscopy, we find that these systems populate conformationally variable relative orientations reflecting the symmetry of the coupled components and the computationally designed interface energy landscape. These mechanical systems with internal degrees of freedom are a step toward the design of genetically encodable nanomachines.Interlayer excitons, electron-hole pairs bound across two monolayer van der Waals semiconductors, offer promising electrical tunability and localizability. Because such excitons display weak electron-hole overlap, most studies have examined only the lowest-energy excitons through photoluminescence. We directly measured the dielectric response of interlayer excitons, which we accessed using their static electric dipole moment. We thereby determined an intrinsic radiative lifetime of 0.40 nanoseconds for the lowest direct-gap interlayer exciton in a tungsten diselenide/molybdenum diselenide heterostructure. We found that differences in electric field and twist angle induced trends in exciton transition strengths and energies, which could be related to wave function overlap, moiré confinement, and atomic reconstruction. Through comparison with photoluminescence spectra, this study identifies a momentum-indirect emission mechanism. Characterization of the absorption is key for applications relying on light-matter interactions.There is much to learn from the farming practices of ants, termites, and other insects.Chemotherapies that induce new DNA errors may help unleash the immune system on tumors.Study suggests feathers arose-and were used for display-well before reign of dinosaurs.Although behavioral interventions are designed to seize attention, little consideration has been given to the costs of doing so. We estimated these costs in the context of a safety campaign that, to encourage safe driving, displays traffic fatality counts on highway dynamic message signs for 1 week each month. We found that crashes increase statewide during campaign weeks, which is inconsistent with any benefits. Furthermore, these effects do not persist beyond campaign weeks. Our results show that behavioral interventions, particularly negatively framed ones, can be too salient, crowding out more important considerations and causing interventions to backfire-with costly consequences.
