Midwives possess many of the skills required for leadership, but the extent to which they contribute to leadership in emergencies is unknown. In this video analysis study of 16 interprofessional teams responding to a simulated post-partum hemorrhage, a functional view of leadership was applied to determine midwifery contribution to leadership. The number and type of leadership utterances by team members during an emergency response was assessed, and midwifery and doctor leadership utterances compared. Midwives contributed just over 40% of all leadership utterances, indicating the occurrence of interprofessional shared leadership, despite the recommendation for a singular leadership. While the number of leadership utterances per scenario was similar for midwives and doctors, midwives contributed less to utterances of a clinical nature compared to doctors but a similar amount of non-clinical leadership. Further exploration of the factors which influence midwifery leadership in emergencies and the impact it may have on patient care is warranted.</p>","PeriodicalId":1,"journal":{"name":"Accounts of Chemical Research","volume":" ","pages":"567-573"},"PeriodicalIF":16.4,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48795107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Middle ear inspection was performed 1 year after the injury due to worsening vertigo upon head movement in Case 2.Main outcome measuresHearing outcomes and vestibular evaluations were presented for the 3 cases, and all comparable cases in the literature were reviewed.ResultsAll 25 patients had a history of traumatic TM perforation, with perforations mostly located in the posterior or posterior superior quadrant (16 cases).

Crystalline porous materials (CPMs), such as metal-organic frameworks (MOFs), covalent organic frameworks (COFs), metal-organic cages (MOCs), and hydrogen-bonded organic frameworks (HOFs), have emerged as exceptional candidates for high-performance adsorbents and membranes due to their intrinsic structural tunability. Their orderly pore structure, high porosity, and large surface facilitate gas storage and separation processes. Furthermore, modifying the inner surface, controlling the pore size, and regulating the framework flexibility can significantly enhance CPMs' adsorption capacity and separation selectivity. Therefore, the precise structure regulation of CPMs is the key to optimizing gas separation and purification.Reticular chemistry is the use of strong chemical bonds to connect discrete molecular structures (molecules or molecular clusters) to create extended structures, such as CPMs. It allows precise atomic-level control and offers a method for regulating the structures of CPMs, enabling tailored pore environments that enhance selectivity for target separations. This approach is crucial to designing effective gas separation materials. For example, by functionalizing organic ligands, regulating metal ions, and modifying secondary building units, the pore size, porosity, and functionality of CPMs can be finely controlled while keeping the framework topology unchanged, thereby optimizing the gas separation performance.In this Account, we present an overview of our group's research efforts on optimizing gas separation by fine-tuning CPM adsorbents and membranes. Using reticular chemistry, we have developed strategies such as multiple cooperative regulation, adaptive pore control, pore environment engineering, preprocessed monomer interfacial polymerization, and precursor solution processing to create highly selective CPM adsorbents and membranes. Additionally, we elucidate the underlying mechanism of multiple hydrogen bonding and dipole-dipole interactions between CPMs and hydrocarbon molecules. By precise structural regulation, we further optimize the gas separation performance and broaden CPMs' applications. Finally, we discuss the challenges and future directions for CPM adsorbents and membranes, including material design, synthesis, stability, performance, and the structure-activity relationship. We also propose a membrane-adsorptive separation coupling technology as a potential solution for achieving high-purity gas separation. By utilizing CPM-based adsorbents and membranes, we aim to establish an energy-intensive and environmentally friendly pathway for the separation of low-carbon hydrocarbons, hydrogen, and natural gas, providing a sustainable alternative to conventional high-energy gas separation processes.</p>","PeriodicalId":1,"journal":{"name":"Accounts of Chemical Research","volume":" ","pages":"1937-1950"},"PeriodicalIF":16.4,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This information might help prevent injury to the neurovascular bundle.MethodsA retrospective evaluation of paranasal sinus CT scans of 100 consecutive random patients, 200 sides, was performed. Five measurements related to the course of the GPC were conducted, from cranial to caudal. The anatomical landmarks were the inferior bony border of the sphenopalatine foramen to the cranial entrance of the GPC, the distance from the most dorsal, and inferior bony insertion of the middle turbinate and the inferior turbinate bones to the anterior margin of the GPC. The angle between the horizontal palatine bone and the GPC, its length, and the prevalence of osteophytes in GPC was also assessed.ResultsThe mean distance of the inferior border of the sphenopalatine foramen to the cranial entrance of the GPC was 9.39 ± 1.72 mm. The mean distance of the dorsal insertion of the middle turbinate to the anterior margin of the GPC was 3.89 ± 0.93 mm.

The standard treatment for ENS is an inferior meatus augmentation procedure (IMAP) in which autologous tissue such as auricular cartilage, rib cartilage, or artificial material is transplanted into the nasal cavity. However, some challenges like a very small auricular cartilage are associated with these autologous tissue types. Moreover, since using rib cartilage is a highly invasive technique, the scar on the chest from where the harvesting is done is easily visible, and the artificial material is susceptible to infection. We used autologous dermal fat (ADF) in IMAPs in our study for the following reasons: the quantity of ADF could be increased or reduced as needed, ADF is considered a safer option than rib cartilage because it is harvested from superficial tissue, it is superior in terms of cosmetic appearance to harvested rib cartilage, and it has a lower risk of infection than any artificial material.<b>Objective:</b> The purpose of our study was to investigate the efficacy and safety of IMAPs using ADF.<b>Methods:</b> We included nine patients with ENS who underwent an IMAP using ADF.
