This study aims to address this gap by investigating the critical factors in succession planning for nursing program administrators. The research objectives include identifying the competencies necessary for academic administrators, assessing the experience of current administrators, and developing a comprehensive succession plan framework. The research uses qualitative methods, including literature review, interviews with nursing administrators, and analysis of existing succession models. Results highlight the importance of integrating strategic planning into succession processes to ensure smooth transitions and organizational stability. Conclusions suggest that a formalized succession plan, incorporating mentorship and leadership development, can mitigate leadership gaps in nursing academia [2].展开更多

文摘The global spread of severe acute respiratory syndrome coronavirus 2 has resulted in a significant number of individuals developing pulmonary fibrosis(PF),an irreversible lung injury.This condition can manifest within a short inter-val following the onset of pneumonia symptoms,sometimes even within a few days.While lung transplantation is a potentially lifesaving procedure,its limited availability,high costs,intricate surgeries,and risk of immunological rejection present significant drawbacks.The optimal timing of medication administration for coronavirus disease 2019(COVID-19)-induced PF remains controversial.Despite this,it is crucial to explore pharmacotherapy interventions,involving early and preventative treatment as well as pharmacotherapy options for advanced-stage PF.Additionally,studies have demonstrated disparities in anti-fibrotic treatment based on race and gender factors.Genetic mutations may also impact therapeutic efficacy.Enhancing research efforts on pharmacotherapy interventions,while considering relevant pharmacological factors and optimizing the timing and dosage of medication administration,will lead to enhanced,personalized,and fair treatment for individuals impacted by COVID-19-related PF.These measures are crucial in lessening the burden of the disease on healthcare systems and improving patients'quality of life.

文摘Land use conflicts(LUCs),as a spatial manifestation of the conflicts in the human-land relationships,have a profound impact on regional sustainable development.For China’s metropolitan junction areas(MJAs),the existence of“administrative district economies”has made the issue of LUCs more prominent.Based on a case study of the central Chengdu–Chongqing region,we conducted an exploratory spatial data analysis of the evolutionary process of regional LUCs.Furthermore,structural equation modeling was utilized to analyze the dynamic mechanism of LUCs in MJAs,with a particular emphasis on exploring the influences of administrative boundary.The results showed that from 2010 to 2020,LUCs in the central Chengdu–Chongqing region continued to worsen,and the spatial process conflict and spatial structure conflict indices increased by more than 30.0%.The intensification of LUCs in the central Chengdu–Chongqing region from 2010 to 2020 was mainly the result of the deterioration of conflicts in evaluation units with low conflict levels.LUCs in China’s metropolitan areas generally presented a circular gradient distribution,weakening from the core to the periphery,but there were some strong isolated conflict zones in the outer regions.LUCs in China’s MJAs were the result of interactions among multiple factors,e.g.,natural environment,socio-economic development,policy and institutional processes,and administrative boundary effects.Administrative boundary affected the flow of socio-economic elements,changing the supply-and-demand competition of stakeholders for land resources,consequently exerting an indirect influence on LUCs.This study advances the theory of the dynamic mechanism of LUCs,and provides theoretical support for the governance of these conflicts in transboundary areas.
文摘Zoonotic hookworm infections remain a significant public health problem,causing nearly 500 milion cases globally and approximately four million disability-adjusted life years lost annually.More than one-fth of these cases are attrib-uted to Ancylostoma ceylanicum,an emerging zoonotic health issue in the Asia-Pacific region.This review presents key research gaps regarding the epidemiology,diagnosis,control,prevention and elimination of A.ceylanicum and other canine zoonotic hookworms as neglected health threats.A.ceylanicum is the second most prevalent human hook-worm in the region;it is the most common hookworm among dogs and cats-reservoirs of zoonotic infections.Previous population genetic and phylogenetic analyses revealed that A.ceylanicum has three possible transmis-sion dynamics:zoonotic,animal-only,and human-only pathways.The actual burden of zoonotic ancylostomiasis in most endemic countries remains unknown due to the use of parasitological techniques(e.g.,Kato-Katz thick smear and floatation techniques)that have reduced diagnostic performance and do not allow accurate species identifica-tion in helminth surveys.The emergence of benzimidazole resistance in soil-transmitted helminths(STHs),includ-ing hookworms,is a concern due to the protracted implementation of mass drug administration(MDA).Resistance is conferred by single nucleotide polymorphisms(SNPs)that occur in theβ-tubulin isotype 1 gene.These mutations have been reported in drug-resistant A.caninum but have not been found in A.ceylanicum in the field.A.ceylanicum remains understudied in the Asia-Pacific region.The zoonotic nature of the parasite warrants investigation of its occur-rence in human and animal reservoir hosts to understand the dynamics of zoonotic transmission in different endemic foci.The detection of benzimidazole resistance-associated SNPs in zoonotic hookworms from Asia-Pacific countries has yet to be thoroughly explored.Considering the high level of hookworm endemicity in the region,the circulation of resistant isolates between humans and animals potentially presents a significant One Health threat that can under-mine current MDA and proposed animal deworming-based control efforts.

文摘BACKGROUND The management of offenders with mental disorders has been a significant concern in forensic psychiatry.In Japan,the introduction of the Medical Treatment and Supervision Act in 2005 addressed the issue.However,numerous psychiatric patients at risk of violence still find themselves subject to the administrative involuntary hospitalization(AIH)scheme,which lacks clarity and updated standards.AIM To explore current as well as optimized learning strategies for risk assessment in AIH decision making.METHODS We conducted a questionnaire survey among designated psychiatrists to explore their experiences and expectations regarding training methods for psychiatric assessments of offenders with mental disorders.RESULTS The findings of this study’s survey suggest a prevalent reliance on traditional learning approaches such as oral education and on-the-job training.CONCLUSION This underscores the pressing need for structured training protocols in AIH consultations.Moreover,feedback derived from inpatient treatment experiences is identified as a crucial element for enhancing risk assessment skills.

文摘Infections caused by intracellular bacterial pathogens are difficult to treat since most antibiotics have low cell permeability and undergo rapid degradation within cells.The rapid development and dissemination of antimicrobial–resistant strains have exacerbated this dilemma.With the increasing knowledge of host–pathogen interactions,especially bacterial strategies for survival and proliferation within host cells,host-directed therapy(HDT)has attracted increased interest and has emerged as a promising antiinfection method for treating intracellular infection.Herein,we applied a cell-based screening approach to a US Food and Drug Administration(FDA)-approved drug library to identify compounds that can inhibit the intracellular replication of Salmonella Typhimurium(S.Typhimurium).This screening allowed us to identify the antidiarrheal agent loperamide(LPD)as a potent inhibitor of S.Typhimurium intracellular proliferation.LPD treatment of infected cells markedly promoted the host autophagic response and lysosomal activity.A mechanistic study revealed that the increase in host autophagy and elimination of intracellular bacteria were dependent on the high expression of glycoprotein nonmetastatic melanoma protein B(GPNMB)induced by LPD.In addition,LPD treatment effectively protected against S.Typhimurium infection in Galleria mellonella and mouse models.Thus,our study suggested that LPD may be useful for the treatment of diseases caused by intracellular bacterial pathogens.Moreover,LPD may serve as a promising lead compound for the development of anti-infection drugs based on the HDT strategy.
文摘The recently published mini-review article by Miotti et al is an effort to clarify various aspects regarding the choice between fat grafts and fillers in facial aesthetic surgery.One of the complications associated with the administration of fillers is the possibility of vascular injury and spread of the dermal filler into the orbit,causing unexpected effects at a site distant from that of the initial injection,including ophthalmoplegia,ptosis and even visual compromise.Acute vision loss following filler injection is a devastating complication,occurring in up to 0.0008%of cases.The greatest risk of this complication occurs with nasal augmentation,followed by glabellar wrinkle treatment.While injected autologous fat predominantly occludes the proximal portion of the ophthalmic artery,hyaluronic acid fillers obstruct the ophthalmic artery comparatively distally.Treatment interventions include thrombolysis,hyperbaric oxygen therapy,oral aspirin,cobamamide and acetazolamide and administration of corticosteroids.However,most studies show a poor prognosis in the form of partial or no recovery of vision.Hence,prevention is of paramount importance.A high index of suspicion is also warranted on the part of both those administering as well as receiving injections of facial fillers to prevent potentially vision-threatening complications of this seemingly innocuous procedure.

文摘The Biden administration’s tariff hikes on Chinese products came,unsurprisingly,a month or so before the first 2024 presidential debate between incumbent U.S.President Joe Biden and former President Donald Trump.They are thus preparing to play the China card once more.Biden has announced tariff increases across key sectors,purportedly to“protect American workers and businesses from China’s unfair trade practices,”according to the White House.The White House Fact Sheet also emphasizes the Biden administration’s creation of jobs in key sectors,as a countermeasure to the Trump administration’s failed China strategy to increase American exports and boost American manufacturing.The administration’s political agenda is thus laid bare.
文摘Leadership succession in nursing academic programs poses a significant challenge, primarily due to the limited availability of professionals with the competencies required for effective leadership [1]. This study aims to address this gap by investigating the critical factors in succession planning for nursing program administrators. The research objectives include identifying the competencies necessary for academic administrators, assessing the experience of current administrators, and developing a comprehensive succession plan framework. The research uses qualitative methods, including literature review, interviews with nursing administrators, and analysis of existing succession models. Results highlight the importance of integrating strategic planning into succession processes to ensure smooth transitions and organizational stability. Conclusions suggest that a formalized succession plan, incorporating mentorship and leadership development, can mitigate leadership gaps in nursing academia [2].
