Objectives This research describes the experiences of emergency departments (EDs) with geriatric fall programs and qualitatively synthesizes lessons learned to inform other EDs planning new fall program implementation. Methods By using grounded theory, we conducted semi-structured, open-ended telephone/skype interviews of emergency physicians and geriatric providers recruited from a purposeful sampling technique. The interviews were transcribed and reviewed by two investigators. The codes were generated and listed, and common concepts emerged. Lastly, the final codes were organized into concepts and themes with the aim to create a strong coding structure. Result The main lessons learned are: (1) understand the hospitals existing local environment and resources, (2) utilize champions and interdisciplinary teams, (3) acknowledge that specific fall assessment tools and interventions vary widely between institutions, (4) engage in routine plan-do-study-act (PDSA) cycles to improve the quality of fall initiatives, and (5) operate under the principle that falls are a syndrome, which must be incorporated within the multifactorial medical needs of geriatric fall patients. Conclusion Based on the lessons learned from our ED fall implementation pioneers, implementing an effective geriatric fall protocol in an ED setting is complicated. Understanding a hospitals resources, assigning champions, working as an interdisciplinary team, choosing proper fall assessment tools/interventions, and completing regular PDSA cycles are important lessons for ED programs planning to implement their own ED fall programs.
Lessons Learned From Emergency Department Fall Assessment and Prevention Programs
Drug discoveries can, when used appropriately, save lives. Since 1970, cancer death rates among people aged under 65 have halved in countries such as the USA and the UK. Despite pharmaceutical market imperfections and fears about the prices of new treatments, further progress should be possible during the 2020s. Anticancer medicine outlays account for 0.1C0.2% of the gross domestic product (GDP) of developed countries. Total cancer service spending typically stands at 0.8% of GDP. The affordability of these sums is a political calculation. Improvements in the efficiency of drug development and global access to effective therapies are desirable. However, from a public interest perspective, these goals should not be pursued in ways that understate the value of better treatment outcomes and threaten the funding available for ongoing innovation.

Social workers and nurses, as members of interprofessional palliative medicine teams, faced unfamiliar challenges and opportunities as they endeavored to provide humanistic care to patients and families during the coronavirus (COVID-19) pandemic. Typical methods for engaging patients and families in medical decision-making became thwarted by visitation restrictions and patients' dramatic health declines. This paper presents an innovative social work and nursing intervention aimed at enhancing humanistic patient/family care and advanced directive dialogs. Through incorporating a narrative synthesis of the teams' reflective journals from COVID-19, the paper chronicles the intervention implementation, patient/family responses, and team members' personal and professional meaning-making processes.
Hearts above water: Palliative care during a pandemic
Coronavirus disease 2019 (COVID-19) is an important health problem that was defined as a pandemic by the World Health Organization on 11 March 2020. Although great concern has been expressed about COVID-19 infection acquired through ocular transmission, its underlying mechanism has not currently been clarified. In the current work, we analyzed and elucidated the two main elements that should be taken into account to understand the ocular route, both from a clinical and molecular point of view. They are represented by the dynamism of the ocular surface system (e.g., the tear film turnover) and the distribution of ACE2 receptors and TMPRSS2 protein. Although it seems, at the moment, that there is a low risk of coronavirus spreading through tears, it may survive for a long time or replicate in the conjunctiva, even in absence of conjunctivitis signs, indicating that eye protection (e.g., protective goggles alone or in association with face shield) is advisable to prevent contamination from external droplets and aerosol.

Microbiomes are integral components of diverse ecosystems, and increasingly recognized for their roles in the health of humans, animals, plants, and other hosts. Given their complexity (both in composition and function), the effective study of microbiomes (microbiomics) relies on the development, optimization, and validation of computational methods for analyzing microbial datasets, such as from marker-gene (e.g., 16S rRNA gene) and metagenome data. This review describes best practices for benchmarking and implementing computational methods (and software) for studying microbiomes, with particular focus on unique characteristics of microbiomes and microbiomics data that should be taken into account when designing and testing microbiomics methods.

With 63,098 confirmed cases on 17 April 2020 and 11,384 deaths, Lombardy has been the most affected region in Italy by coronavirus disease 2019 (COVID-19). To cope with this emergency, the COVID-19 Lombardy intensive care units (ICU) network was created. The network identified the need of defining a list of clinical recommendations to standardize treatment of patients with COVID-19 admitted to Intensive Care Unit (ICU). Three core topics were identified: 1) rational use of intensive care resources; 2) ventilation strategies; 3) non-ventilatory interventions. Identification of patients who may benefit from ICU treatment is challenging. Clinicians should consider baseline performance and frailty status and they should adopt disease-specific staging tools. Continuous positive airway pressure, mainly delivered through a helmet as elective method, should be considered as initial treatment for all patients with respiratory failure associated with COVID-19. In case of persisting dyspnea and/or desaturation despite 4-6 hours of noninvasive ventilation, endotracheal intubation and invasive mechanical ventilation should be considered. In the early phase, muscle relaxant use and volume-controlled ventilation is recommended. Prone position should be performed in patients with PaO2/FiO2100 mmHg. For patients admitted to ICU with COVID-19 interstitial pneumonia, we do not recommend empiric antibiotic therapy for community-acquired pneumonia. Consultation of an infectious disease specialist is suggested before start of any antiviral therapy. In conclusion, the COVID-19 Lombardy ICU Network identified a list of best practice statements supported by the available evidence and clinical experience or identified as panel members expert opinions for the management of critically ill patients with COVID-19.

Agroforestry consists of combining trees with agriculture, both on farms and in the agricultural landscape. Within a context of sustainable development, agroforestry can improve soil conservation and reduce the use of toxic chemicals on crops, as well as improving biodiversity. Interdisciplinary by nature, the field of agroforestry mobilizes a large body of knowledge from environmental and life sciences using systemic approaches. In this framework, field observation data are acquired in partnership with several categories of stakeholders such as scientists, foresters, farmers, breeders, politicians and land managers. For data management efficiency, we propose the software application AOBRA (a software Application with Ontology-Based Reasoning for Agroforestry). The core of AOBRA is a domain ontology called Agroforestry which serves as a basis for capitalizing and sharing knowledge in agroforestry. By exploiting the capabilities of inference and linkages to other areas of expertise on the Web offered by the use of an ontology model, it aims to provide a broad view of agroforestry designs, and to allow the comparison between different spatial layouts of trees and crops.

BACKGROUND AND IMPORTANCE Basilar fenestration aneurysms are rare, challenging intracranial vascular lesions with atypical anatomy. The posterior circulation represents a difficult therapeutic dilemma because of the close proximity of crucial life-sustaining brainstem structures. The use of flow diverter technology has been very limited in posterior circulation vessels. CLINICAL PRESENTATION We present the case of a 49-year-old female patient, who was diagnosed with a symptomatic large vertebrobasilar junction aneurysm, which was initially thought to be a proximal basilar dilatation. The aneurysm was later verified to arise from the proximal end of a basilar fenestration, distended by the aneurysm fundus. The small-caliber fenestration limbs were the only connection to the distal basilar artery, but were stretched laterally and concealed by the aneurysm fundus. This complex lesion was successfully treated by flow diverter deployment through one of the fenestration limbs, followed by coiling of the aneurysm fundus, and sacrificing the contralateral vertebral artery. A 6-month follow-up angiogram showed remodeling of the basilar artery and complete occlusion of the aneurysm with good clinical outcome. Careful diagnostic workup, multidisciplinary discussions, and the innovative use of versatile endovascular technology were crucial to achieve an optimal result in this case. CONCLUSION This is the first report of a successful basilar artery reconstruction for the treatment of a large atypical vertebrobasilar junction fenestration aneurysm by deployment of a flow diverter device directly in a small, obscured fenestration limb.

Most countries are suffering severely from the ongoing covid-19 pandemic despite various levels of preventive measures. A common question is if and when a country or region will reach herd immunity $h$. The classical herd immunity level $h_C$ is defined as $h_C=1-1/R_0$, where $R_0$ is the basic reproduction number, for covid-19 estimated to lie somewhere in the range 2.2-3.5 depending on country and region. It is shown here that the disease-induced herd immunity level $h_D$, after an outbreak has taken place in a country/region with a set of preventive measures put in place, is actually substantially smaller than $h_C$. As an illustration we show that if $R_0=2.5$ in an age-structured community with mixing rates fitted to social activity studies, and also categorizing individuals into three categories: low active, average active and high active, and where preventive measures affect all mixing rates proportionally, then the disease-induced herd immunity level is $h_D=43\%$ rather than $h_C=1-1/2.5=60\%$. Consequently, a lower fraction infected is required for herd immunity to appear. The underlying reason is that when immunity is induced by disease spreading, the proportion infected in groups with high contact rates is greater than that in groups with low contact rates. Consequently, disease-induced immunity is stronger than when immunity is uniformly distributed in the community as in the classical herd immunity level.
The disease-induced herd immunity level for Covid-19 is substantially lower than the classical herd immunity level
This is the second in a two\part review of diagnostic cytopathology in veterinary medicine. As in human medicine, cytopathology is a minimally invasive, rapid, and cost\effective diagnostic modality with broad utilization. In this second part, the diagnostic applications of cytology in respiratory, gastrointestinal, genitourinary, endocrine, ocular, and central nervous system tissues are discussed with a section describing fluid analysis in veterinary medicine. As noted in the previous manuscript, which characterized the cytology of the skin/subcutis, musculoskeletal, and lymphoid tissues, the interpretation of veterinary cytology samples must be undertaken with extensive knowledge of the breadth of animal species, including familiarity with the frequency and clinical progression of diseases, both of which can be influenced by species, breed, and husbandry conditions. Similar to part one, this review focuses on the most common domestic companion animal species (dog, cat, and horse) and highlights lesions that are either unique to veterinary species or have relevant correlates in people. The cytologic features and biological behavior of similar lesions are compared, and selected mechanisms of disease and ancillary diagnostics are reviewed when appropriate. Supporting figures illustrate a subset of lesions. While not an exhaustive archive of veterinary cytology, the goal is to give cytopathologists working in human medicine a general impression of correlates and unique entities in veterinary practice.

Immune-mediated necrotizing myopathy (IMNM) is a rare form of idiopathic immune myopathy (IIM) that requires immunotherapies, including immunosuppressive medications, if severe. There is a paucity of data regarding outcomes of patients with immune-mediated polymyositis who continue immunosuppressive medications during the COVID-19 pandemic. This is the first reported case of COVID-19 in a patient with IMNM. Despite being on two immunotherapies, having risk factors, and having radiographic abnormalities on chest X-ray, the patient had an unremarkable COVID-19 course. He was discharged from the emergency department with a 7-day course of azithromycin and quickly resumed his immunotherapies, but he experienced a flare in his myositis. The 14-week follow-up computed tomography (CT) was negative for residual pneumonitis or fibrosis. More data are needed regarding management and prognosis of patients with connective tissue diseases who become infected with SARS-CoV-2.

Background: The coronavirus disease 2019 (COVID-19) pandemic has the potential to trigger multiple stress domains and lead to long-term repercussions in an individuals quality of life, health, and well-being. Stressors from the pandemic are likely to be experienced in many ways by older adults with heterogeneous life experiences and supports available. In this context, it is necessary to tease out the underlying mechanisms leading to positive and negative well-being and mental health across interdependent individual, social and environmental factors. The aim of the present study is to explore community-dwelling older adults experiences during the COVID-19 pandemic, with a particular focus on mental health and psychosocial well-being. Methods: : An exploratory longitudinal qualitative study will be conducted with data collected through written submissions, narrative interviews and go-along interviews with older adults living in Irish community settings. To enable the exploration of participants responses to the evolving social, economic and environmental circumstances, data collection will take during the implementation of public health restrictions and once these are eased and the vaccination program is rolled out. Framework analysis will be carried out to identify data themes, linkages, and explanations within Bronfenbrenners socio-ecological model. Ethics and dissemination: Ethical approval has been granted by the Royal College of Surgeons in Ireland, Research Ethics Committee (REC202011028). Findings will be disseminated through peer-reviewed journal publications, presentations at relevant conferences, and in consultation with Public and Patient Involvement (PPI) contributors. A lay summary of findings and infographic will be distributed to multiple stakeholders including our PPI panel, older people, caregivers, community organizations, charities, and media.
Well-being, Interventions and Support during Epidemics (WISE): Protocol for a qualitative longitudinal study of older adults experiences during COVID-19
OBJECTIVES: To gain insight into willingness and its influencing factors to vaccinate against COVID-19 among health care workers (HCWs), and provide a scientific basis for more reasonable epidemic prevention and control strategies. METHODS: A comprehensive literature search was conducted in four English databases (PubMed, EMBASE, Web of Science and the Cochrane Library) and four Chinese databases (Chinese National Knowledge Infrastructure (CNKI), the Chongqing VIP Chinese Science (VIP), Wanfang Database and China Biomedical Literature Database (CBM)) to collect the related studies. Quality evaluation was carried out for papers meeting the inclusion criteria using six items from the Downs and Black assessment checklist. The STATA statistical software version 15.1 was hired to perform meta-analysis. RESULTS: Nine records with a total of 24,952 subjects were included in this meta-analysis. The results of this meta-analysis revealed that the pooled effect value of COVID-19 vaccination willingness among HCWs using a random-effects model was 51% (95% confidence interval (CI) 0.41-0.62). Male, aged 30 years or older, having a history of prior influenza vaccination were facilitators for HCWs intention to vaccinate against COVID-19 (odds ratio (OR) 1.82, 95% CI 1.37-2.41, P=0.000, I(2)=59.4%; OR 1.32, 95% CI 1.16-1.51, P=0.000, I(2)=31.7%; OR 2.97, 95% CI 1.82-4.84, P=0.000, I(2)=88.1%). The impact of occupation on HCWs intention to get vaccinated could not yet be definitively confirmed (OR 0.85, 95% CI 0.69-1.06, P=0.160, I(2)=85.5%). CONCLUSION: COVID-19 vaccination acceptance of HCWs was at moderate level. Strengthening awareness of COVID-19 vaccine among HCWs, particularly female HCWs under 30 years who have no history of prior influenza vaccination, is crucial to eliminate concerns about vaccination and promote the application of COVID-19 vaccine in this population.

OBJECTIVES: To describe the association between population size, population growth and opioid overdose deathsoverall and by type of opioidin US commuting zones (CZs) in three periods between 2005 and 2017. SETTINGS: 741 CZs covering the entirety of the US CZs are aggregations of counties based on commuting patterns that reflect local economies. PARTICIPANTS: We used mortality data at the county level from 2005 to 2017 from the National Center for Health Statistics. OUTCOME: Opioid overdose deaths were defined using underlying and contributory causes of death codes from the International Classification of Diseases, 10th revision (ICD-10). We used the underlying cause of death to identify all drug poisoning deaths. Contributory cause of death was used to classify opioid overdose deaths according to the three major types of opioid, that is, prescription opioids, heroin and synthetic opioids other than methadone. RESULTS: Opioid overdose deaths were disproportionally higher in largely populated CZs. A CZ with 1.0% larger population had 1.10%, 1.10%, and 1.16% higher opioid death count in 2005C2009, 2010C2014, and 2015C2017, respectively. This pattern was largely driven by a high number of deaths involving heroin and synthetic opioids, particularly in 2015C2017. Population growth over time was associated with lower age-adjusted opioid overdose mortality rate: a 1.0% increase in population over time was associated with 1.4% (95% CI: ?2.8% to 0.1%), 4.5% (95% CI: ?5.8% to ?3.2%), and 1.2% (95% CI: ?4.2% to 1.8%) lower opioid overdose mortality in 2005C2009, 2010C2014, and 2015C2017, respectively. The association between positive population growth and lower opioid mortality rates was stronger in larger CZs. CONCLUSIONS: Opioid overdose mortality in the USA was disproportionately higher in mid-sized and large CZs, particularly those affected by declines in population over time, regardless of the region where they are located.

Due to a high unresponsiveness to chemotherapy, biofilm formation is an important medical problem that frequently occurs during infection with many bacterial pathogens. In this study, the marine sponge-derived natural compounds 4,6-dibromo-2-(2',4'-dibromophenoxy)phenol and 3,4,6-tribromo-2-(2',4'-dibromophenoxy)phenol were found to exhibit broad antibacterial activity against medically relevant gram-positive and gram-negative pathogens. The compounds were not only bactericidal against both replicating and stationary phase-persistent planktonic cells of methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa; they also killed biofilm-incorporated cells of both species while not affecting biofilm structural integrity. Moreover, these compounds were active against carbapenemase-producing Enterobacter sp. This simultaneous activity of compounds against different growth forms of both gram-positive and gram-negative bacteria is rare. Genome sequencing of spontaneous resistant mutants and proteome analysis suggest that resistance is mediated by downregulation of the bacterial EIIBC phosphotransferase components scrA and mtlA in MRSA likely leading to a lower uptake of the molecules. Due to their only moderate cytotoxicity against human cell lines, phenoxyphenols provide an interesting new scaffold for development of antimicrobial agents with activity against planktonic cells, persisters and biofilm-incoporated cells of ESKAPE pathogens. KEY POINTS: ? Brominated phenoxyphenols kill actively replicating and biofilm-incorporated bacteria. ? Phosphotransferase systems mediate uptake of brominated phenoxyphenols. ? Downregulation of phosphotransferase systems mediate resistance.
Natural brominated phenoxyphenols kill persistent and biofilm-incorporated cells of MRSA and other pathogenic bacteria.
Recently, highly transmissible SARS-CoV-2 variants B.1.617.1 (Kappa), B.1.617.2 (Delta) and B.1.618 were identified in India with mutations within the spike proteins. The spike protein of Kappa contains four mutations E154K, L452R, E484Q and P681R, and Delta contains L452R, T478K and P681R, while B.1.618 spike harbors mutations 145-146 and E484K. However, it remains unknown whether these variants have altered in their entry efficiency, host tropism, and sensitivity to neutralizing antibodies as well as entry inhibitors. In this study, we found that Kappa, Delta or B.1.618 spike uses human ACE2 with no or slightly increased efficiency, while gains a significantly increased binding affinity with mouse, marmoset and koala ACE2 orthologs, which exhibits limited binding with WT spike. Furthermore, the P618R mutation leads to enhanced spike cleavage, which could facilitate viral entry. In addition, Kappa, Delta and B.1.618 exhibits a reduced sensitivity to neutralization by convalescent sera owning to the mutation of E484Q, T478K, 145-146 or E484K, but remains sensitive to entry inhibitors-ACE2-lg decoy receptor. Collectively, our study revealed that enhanced human and mouse ACE2 receptor engagement, increased spike cleavage and reduced sensitivity to neutralization antibodies of Kappa, Delta and B.1.618 may contribute to the rapid spread of these variants and expanded host range. Furthermore, our result also highlighted that ACE2-lg could be developed as broad-spectrum antiviral strategy against SARS-CoV-2 variants.

PURPOSE: To examine the prevalence of depressive and anxiety symptoms and the corresponding risk factors among pregnant women during the confinement due to the COVID-19 outbreak in Spain. MATERIALS AND METHODS: Between 15 April and 14 May 2020, a multicentre cross-sectional survey was performed to study depression, anxiety and resilience in a sample of Spanish pregnant women during the lockdown set up by the Government in response to COVID-19 pandemic outbreak. We designed an anonymous online self-administered questionnaire (https://bit.ly/34RRpq1) that included the Spanish validated versions of the Edinburgh Postpartum Depression Scale (EPDS), the State-Trait Anxiety Inventory (STAI) and the Connor-Davidson Resilience 10-items Scale (CD-RISC-10). RESULTS: A total of 514 pregnant women completed the survey. 72.8% had been confined < 40 days and 27.2% between 41 and 60 days. 182 (35.4%) participants scored over 10, with 21.3% scoring over 13 (75th Percentile) in depressive symptoms rates. We found high trait and anxiety scores, with 223 (43.4%) and 227 (44.2%) pregnant women scoring over the trait and state mean scores. Neither depression, anxiety or resilience levels showed any significant correlation with the length of confinement. We found low CD-RISC-10 scores. CONCLUSIONS: We found a high prevalence of depression and anxiety symptoms during the quarantine, although we did not find an increased prevalence of psychological distress according to length of home confinement. Resilience correlated negatively with depression and anxiety.

Haemoglobin degradation during the erythrocytic life stages is the major function of the food vacuole (FV) of Plasmodium falciparum and the target of several anti-malarial drugs that interfere with this metabolic pathway, killing the parasite. Two multi-spanning food vacuole membrane proteins are known, the multidrug resistance protein 1 (PfMDR1) and Chloroquine Resistance Transporter (PfCRT). Both modulate resistance to drugs that act in the food vacuole. To investigate the formation and behaviour of the food vacuole membrane we have generated inducible GFP fusions of chloroquine sensitive and resistant forms of the PfCRT protein. The inducible expression system allowed us to follow newly-induced fusion proteins, and corroborated a previous report of a direct trafficking route from the ER/Golgi to the food vacuole membrane. These parasites also allowed the definition of a food vacuole compartment in ring stage parasites well before haemozoin crystals were apparent, as well as the elucidation of secondary PfCRT-labelled compartments adjacent to the food vacuole in late stage parasites. We demonstrated that in addition to previously demonstrated Brefeldin A sensitivity, the trafficking of PfCRT is disrupted by Dynasore, a non competitive inhibitor of dynamin-mediated vesicle formation. Chloroquine sensitivity was not altered in parasites over-expressing chloroquine resistant or sensitive forms of the PfCRT fused to GFP, suggesting that the PfCRT does not mediate chloroquine transport as a GFP fusion protein.
