In-Hospital Observation on Oral Diuretics After Treatment for Acute Decompensated Heart Failure: Evaluating the Utility

Background: Following treatment for acute decompensated heart failure, in-hospital observation on oral diuretics (OOD) is recommended, assuming it provides actionable information on discharge diuretic dosing and thus reduces readmissions. Methods: In the Mechanisms of Diuretic Resistance (MDR) cohort, we analyzed in-hospital measures of diuretic response, provider’s decisions, and diuretic response ≈30 days postdischarge. In a Yale multicenter cohort, we assessed if in-hospital OOD was associated with 30-day readmission risk. The main objective of this study was to evaluate the utility of in-hospital OOD. Results: Of the 468 patients in the MDR cohort, 57% (N=265) underwent in-hospital OOD. During the OOD, weight change and net fluid balance correlated poorly with each other (r=0.36). Discharge diuretic dosing was similar between patients who had increased, stable, or decreased weight (decreased discharge dose from OOD dose in 77% versus 72% versus 70%, respectively), net fluid status (decreased discharge dose from OOD dose in 100% versus 69% versus 74%, respectively), and urine output (decreased discharge dose from OOD dose in 69% versus 79% versus 72%, respectively) during the 24-hour OOD period (P>0.27 for all). In participants returning at 30 days for formal quantification of outpatient diuretic response (n=98), outpatient and inpatient OOD natriuresis was poorly correlated (r=0.26). In the Yale multicenter cohort (n=18 454 hospitalizations), OOD occurred in 55% and was not associated with 30-day hospital readmission (hazard ratio, 0.98 [95% CI, 0.93–1.05]; P=0.51). Conclusions: In-hospital OOD did not provide actionable information on diuretic response, was not associated with outpatient dose selection, did not predict subsequent outpatient diuretic response, and was not associated with lower readmission rate. Additional research is needed to replicate these findings and understand if these resources could be better allocated elsewhere.

The Discovery and Anti‐Colorectal Cancer Activities of Cembranolides from the South China Sea Soft Coral Sinularia pendunculata

A new cembranolide, namely, sinupendunculide A (1), along with eight known related compounds (2–9), was isolated from the South China Sea Soft coral Sinularia pendunculata. The structure of sinupendunculide A (1) was established by extensive spectroscopic analysis and X‐ray diffraction experiments. In a bioassay, anti‐colorectal cancer (CRC) activity was performed, and the results showed that several compounds exhibited cytotoxicity against RKO cells, and a preliminary structure‐activity relationship was analysed. Meanwhile, the most effective compound 7 was proven to increase reactive oxygen species levels, which promoted cell apoptosis and inhibited cell proliferation.
“Our parents kiss in front of us”: Reasons for early sexual debut among in-school youth in the Manzini Region in Eswatini

Background Early sexual debut (i.e., sex before the age of 15 years), especially if it is unprotected, may increase the risk of acquiring HIV, sexually transmitted infections, and unwanted pregnancies. We investigated the reasons for early sexual debut among in-school youth in Eswatini, a setting with high HIV incidence among youth. Methods This was a qualitative, exploratory-descriptive study whereby data were collected from 81 sexually active in-school youth through seven focus group discussions (FGDs) in four purposively selected public high schools (two urban and two rural) in the Manzini region, Eswatini. In each school, except one, two FGDs (one for boys and one for girls) were conducted. Qualitative data were coded and analyzed thematically in Dedoose version 8.2. 14. Results Nearly 40% of the participants reported having initiated sexual activity before 18 years. Six major themes emerged from the data: i) Intrapersonal factors (feeling mature, religiosity, nutritional or dietary patterns); ii) Parenting and household factors (living arrangement, lack of sexuality education, working parents, negative role-modeling from adults); iii) Peer and partner pressure (pressure from friends, threats from sexual partners, intergenerational sexual partnerships and transactional sex, testing sexual prowess, desire to fit in); iv) Contextual factors (neighborhood, location); v) Mass media (cell phone ownership, social media, and television shows or movies); and vi) Cultural factors (attending traditional ceremonies, loss of cultural norms, values, and traditions, and dress code). Conclusion and recommendations The poor monitoring and negative role-modeling by elders highlight the importance of involving parents or guardians as key stakeholders when designing interventions targeting risky sexual behavior among youth. The multifaceted nature of the cited reasons for early sexual debut calls for interventions aimed at curbing risky sexual behavior to be culturally sensitive and responsive to the themes identified in this study.
Clouds and Shortwave Fluxes at Nauru. Part II: Shortwave Flux Closure

Abstract The datasets currently being collected by the Atmospheric Radiation Measurement (ARM) program on the islands of Nauru and Manus represent the longest time series of ground-based cloud measurements in the tropical western Pacific region. In this series of papers, a shortwave flux closure study is presented using observations collected at the Nauru site between June 1999 and May 2000. The first paper presented frequency of occurrence of nonprecipitating clouds detected by the millimeter-wavelength cloud radar (MMCR) at Nauru and statistics of their retrieved microphysical properties. This paper presents estimates of the cloud radiative effect over the study period and results from a closure study in which retrieved cloud properties are input to a radiative transfer model and the modeled surface fluxes are compared to observations. The average surface shortwave cloud radiative forcing is 48.2 W m−2, which is significantly smaller than the cloud radiative forcing estimates found during the Tropical O.
Impact of enhancing GP access to diagnostic imaging: A scoping review

Background Direct access to diagnostic imaging in General Practice provides an avenue to reduce referrals to hospital-based specialities and emergency departments, and to ensure timely diagnosis. Enhanced GP access to radiology imaging could potentially reduce hospital referrals, hospital admissions, enhance patient care, and improve disease outcomes. This scoping review aims to demonstrate the value of direct access to diagnostic imaging in General Practice and how it has impacted on healthcare delivery and patient care. Methods A search was conducted of ‘PubMed’, ‘Cochrane Library’, ‘Embase’ and ‘Google Scholar’ for papers published between 2012–2022 using Arksey and O’Malley’s scoping review framework. The search process was guided by the PRISMA extension for Scoping Reviews checklist (PRISMA-ScR). Results Twenty-three papers were included. The studies spanned numerous geographical locations (most commonly UK, Denmark, and Netherlands), encompassing several study designs (most commonly cohort studies, randomised controlled trials and observational studies), and a range of populations and sample sizes. Key outcomes reported included the level of access to imaging serves, the feasibility and cost effectiveness of direct access interventions, GP and patient satisfaction with direct access initiatives, and intervention related scan waiting times and referral process. Conclusion Direct access to imaging for GPs can have many benefits for healthcare service delivery, patient care, and the wider healthcare ecosystem. GP focused direct access initiatives should therefore be considered as a desirable and viable health policy directive. Further research is needed to more closely examine the impacts that access to imaging studies have on health system operations, especially those in General Practice. Research examining the impacts of access to multiple imaging modalities is also warranted.
Association Between Parapapillary Microvasculature Dropout and Central Retinal Vessel Trunk in Primary Open Angle Glaucoma

Précis: Central retinal vessel trunk displacement is an important factor in the generation and development of deep-layer microvasculature dropout in primary open angle glaucoma. Purpose: To investigate the association between the microvasculature dropout and the central retinal vessel trunk in primary open angle glaucoma eyes. Methods: In total, 112 eyes from 112 patients with primary open-angle glaucoma were included. Matched 26 no microvasculature dropout eyes and 26 microvasculature dropout eyes, they had similar axial length and global retinal nerve fiber layer thickness. Central retinal vessel trunk shift index was calculated as the distance of the central retinal vessel trunk from the Bruch membrane opening center relative to that of the Bruch membrane opening border. The correlation of the presence, extent, and location of microvasculature dropout and the displacement extent and location of the central retina vessel trunk was analyzed. Results: The central retinal vessel trunk shift index differed significantly between the 2 matched groups. Multivariate logistic analyses showed that in 112 eyes from 112 patients, eyes with microvasculature dropout was significantly associated with larger shift index than eyes without microvasculature dropout. The angular circumference of microvasculature dropout was significantly associated with adjusted shift index (a linear mixed model was constructed, exclude the influence of axial length and global retinal nerve fiber layer thickness on shift index). The location of the microvasculature dropout and central retinal vessel trunk contralateral were significantly correlated. Conclusions: In primary open angle glaucoma eyes, microvasculature dropout and the central retinal vessel trunk were significantly correlated. Because the central retinal vessel trunk represents the structural stability of the lamina cribrosa, microvasculature dropout seems to correlate with lamina cribrosa’s structural stability.
Potential Vorticity of the Madden–Julian Oscillation

AbstractThis study explores the extent to which the dynamical structure of the Madden–Julian oscillation (MJO), its evolution, and its connection to diabatic heating can be described in terms of potential vorticity (PV). The signature PV structure of the MJO is an equatorial quadrupole of cyclonic and anticyclonic PV that tilts westward and poleward. This PV quadrupole is closely related to positive and negative anomalies in precipitation that are in a swallowtail pattern extending eastward along the equator and splitting into off-equatorial branches westward. Two processes dominate the generation of MJO PV. One is linear, involving MJO diabatic heating alone. The other is nonlinear, involving diabatic heating and relative vorticity of perturbations spectrally outside the MJO domain but spatially constrained to the MJO convective envelope. The MJO is thus partially a self-sustaining system and partially a consequence of scale interaction of MJO-constrained stochastic processes. Convective initiation of th.
Tracking the effects of propofol, sevoflurane and (S)-ketamine anesthesia using an unscented Kalman filter-based neural mass model

Objective. Neural mass model (NMM) has been widely used to investigate the neurophysiological mechanisms of anesthetic drugs induced general anesthesia (GA). However, whether the parameters of NMM could track the effects of anesthesia still unknown. Approach. We proposed using the cortical NMM (CNMM) to infer the potential neurophysiological mechanism of three different anesthetic drugs (i.e. propofol, sevoflurane, and (S)-ketamine) induced GA, and we employed unscented Kalman filter (UKF) to track any change in raw electroencephalography (rEEG) in frontal area during GA. We did this by estimating the parameters of population gain [i.e. excitatory/inhibitory postsynaptic potential (EPSP/IPSP, i.e. parameter A/B in CNMM) and the time constant rate of EPSP/IPSP (i.e. parameter a/b in CNMM). We compared the rEEG and simulated EEG (sEEG) from the perspective of spectrum, phase-amplitude coupling (PAC), and permutation entropy (PE). Main results. Under three estimated parameters (i.e. A, B, and a for propofol/sevoflurane or b for (S)-ketamine), the rEEG and sEEG had similar waveforms, time-frequency spectra, and PAC patterns during GA for the three drugs. The PE curves derived from rEEG and sEEG had high correlation coefficients (propofol: 0.97 ± 0.03, sevoflurane: 0.96 ± 0.03, (S)-ketamine: 0.98 ± 0.02) and coefficients of determination (R 2) (propofol: 0.86 ± 0.03, sevoflurane: 0.68 ± 0.30, (S)-ketamine: 0.70 ± 0.18). Except for parameter A for sevoflurane, the estimated parameters for each drug in CNMM can differentiate wakefulness and non-wakefulness states. Compared with the simulation of three estimated parameters, the UKF-based CNMM had lower tracking accuracy under the simulation of four estimated parameters (i.e. A, B, a, and b) for three drugs. Significance. The results demonstrate that a combination of CNMM and UKF could track the neural activities during GA. The EPSP/IPSP and their time constant rate can interpret the anesthetic drug’s effect on the brain, and can be used as a new index for depth of anesthesia monitoring.
Shared Neural Activity But Distinct Neural Dynamics for Cognitive Control in Monkey Prefrontal and Parietal Cortex

To better understand how prefrontal networks mediate forms of cognitive control disrupted in schizophrenia, we translated a variant of the AX continuous performance task that measures specific deficits in the human disease to 2 male monkeys and recorded neurons in PFC and parietal cortex during task performance. In the task, contextual information instructed by cue stimuli determines the response required to a subsequent probe stimulus. We found parietal neurons encoding the behavioral context instructed by cues that exhibited nearly identical activity to their prefrontal counterparts (Blackman et al., 2016). This neural population switched their preference for stimuli over the course of the trial depending on whether the stimuli signaled the need to engage cognitive control to override a prepotent response. Cues evoked visual responses that appeared in parietal neurons first, whereas population activity encoding contextual information instructed by cues was stronger and more persistent in PFC. Increasing cognitive control demand biased the representation of contextual information toward the PFC and augmented the temporal correlation of task-defined information encoded by neurons in the two areas. Oscillatory dynamics in local field potentials differed between cortical areas and carried as much information about task conditions as spike rates. We found that, at the single-neuron level, patterns of activity evoked by the task were nearly identical between the two cortical areas. Nonetheless, distinct population dynamics in PFC and parietal cortex were evident. suggesting differential contributions to cognitive control. SIGNIFICANCE STATEMENT We recorded neural activity in PFC and parietal cortex of monkeys performing a task that measures cognitive control deficits in schizophrenia. This allowed us to characterize computations performed by neurons in the two areas to support forms of cognitive control disrupted in the disease. Subpopulations of neurons in the two areas exhibited parallel modulations in firing rate; and as a result, all patterns of task-evoked activity were distributed between PFC and parietal cortex. This included the presence in both cortical areas of neurons reflecting proactive and reactive cognitive control dissociated from stimuli or responses in the task. However, differences in the timing, strength, synchrony, and correlation of information encoded by neural activity were evident, indicating differential contributions to cognitive control.
Metastable nematic hedgehogs

For nematic liquid crystals, we study the local stability of a radial hedgehog against biaxial perturbations. Our analysis employs the Landau - de Gennes functional to describe the free energy stored in a ball, whose radius is a parameter of the model. We find that a radial hedgehog may be either unstable or metastable, depending on the values of the elastic constants. For unstable hedgehogs, we give an explicit expression for the radius of the ball within which the instability manifests itself: it can be interpreted as the size of the biaxial core of the defect; it is of the same order of magnitude as the radius of the disclination ring predicted by Penzenstadler and Trebin's model. The metastable hedgehogs predicted by our model are the major novelty of the paper. They tell us that we may also expect truly uniaxial point defects, whose core contains no biaxial structure.
Synthesis of [

Background: [F]fluoromisonidazole ([F]FMISO, 1H-1-(3-[F]fluoro2-hydroxypropyl)-2-nitroimidazole) is a commonly used radiotracer for imaging hypoxic conditions in cells. Since hypoxia is prevalent in solid tumors, [F]FMISO is in clinical application for decades to explore oxygen demand in cancer cells and the resulting impact on radiotherapy and chemotherapy. Results: Since the introduction of [F]FMISO as positron emission tomography imaging agent in 1986, a variety of radiosynthesis procedures for the production of this hypoxia tracer has been developed. This paper gives a brief overview on [F]FMISO radiosyntheses published so far from its introduction until now. From a radiopharmaceutical chemist’s perspective, different precursors, radiolabeling approaches and purification methods are discussed as well as used automated radiosynthesizers, including cassette-based and microfluidic systems. Conclusion: In a GMP compliant radiosynthesis using original cassettes for FASTlab we produced [F]FMISO in 49% radiochemical yield within 48 min with radiochemical purities > 99% and molar activities > 500 GBq/μmol. In addition, we report an easy and efficient radiosynthesis of [F]FMISO, based on in-house prepared FASTlab cassettes, providing the radiotracer for research and preclinical purposes in good radiochemical yields (39%), high radiochemical purities (> 99%) and high molar activity (> 500 GBq/ μmol) in a well-priced option.
Estimation of the number of RSV-associated hospitalisations in adults in the European Union

Background: Respiratory syncytial virus (RSV) is a major cause of lower respiratory tract infections in older adults that can result in hospitalisations and death. Estimating RSV-associated hospitalisation is critical for planning RSV-related healthcare needs for the ageing population across Europe. Methods: We gathered national RSV-associated hospitalisation estimates from the REspiratory Syncytial virus Consortium in EUrope (RESCEU) for adults in Denmark, England, Finland, Norway, Netherlands, and Scotland from 2006 to 2017. We extrapolated these estimates to 28 EU countries using nearest-neighbour matching, multiple imputations, and two sets of 10 indicators. Results: On average, 158 229 (95%CI: 140 865, 175 592) RSV-associated hospitalisations occur annually among adults in the EU (above 18 years); 92% of these hospitalisations occur in adults over 65 years. Among 75-84 years old, the annual average is estimated at 74 519 (95%CI: 69 923, 79 115) at a rate of 2.24 (95%CI: 2.10, 2.38) per 1000 adults. Among adults aged 85 years and above, the annual average is estimated at 37 904 (95%CI: 32 444, 43 363) at a rate of 2.99 (95%CI: 2.56, 3.42). Conclusion: Our estimates of RSV-associated hospitalisations in older adults are the first analysis integrating available data to provide estimates of the disease burden in this population across the EU. Importantly, for a condition which was considered in the past to be primarily a disease of young children, the average annual hospitalisation estimate in adults was lower but of a similar magnitude to the estimate in young children aged 0-4 years: 158 229 (95%CI: 140 865, 175 592) versus 245 244 (95%CI: 224 688, 265 799).
A Picture Might Be Worth a Thousand Words, But It's Not Always Enough to Evaluate Robots

Evaluation of robots commonly occurs using various stimuli, including photos, videos, and live interaction. However, a better understanding of how and why chosen stimuli affect perceptions, and how evaluations using lower fidelity media (e.g. photos) compare to evaluations using higher context stimuli (e.g., videos), is needed. Through a survey of 599 M-Turk participants, we compare robot evaluations based on exposure to three types of media - photos, GIFs, and promotional videos. We analyze nine perception and behavioral intention measures of three home robots with varying levels of anthropomorphism (Olly, Jibo, and Liku): overall liking, liking of appearance, liking of intended use, eeriness, human-likeness, performance expectations, privacy concerns, information seeking intention, and purchase intention. We find that photos consistently differ from ratings of videos for all measures, except for liking of robots' intended use. Use of GIFs led to measurements in line with videos for seven of the nine measurements, due to the importance of movement in perceptual assessments and character judgments (e.g., friendly, creepy). Except for the most human-like robot, neither photos nor GIFs captured human-likeness to a similar degree as videos, due to the importance of speech in assessments. Though GIFs captured informational and overall privacy concerns well, they did not adequately capture physical privacy concerns.
Reimagining Robots for Dementia: From Robots for Care-receivers/giver to Robots for Carepartners

Informal caregivers are the main source of dementia care. Considering the importance of both family caregivers and persons living with dementia (PwDs), this paper explores how these two parties go through their dementia journey and how they envision robots to support them. We adopt a person-centered care approach which views these couples as reciprocal carepartners, rather than as care-givers and care-receivers. We conducted a community-based participatory research study with a dementia advocacy organization to imagine how robots can support these dementia dyads. The contribution of this paper is threefold: First, we introduce a person-centered care approach and show how this new approach reveals the issues of PwDs and carepartners (CPs) as partners and citizens. For example, PwDs' main challenges were not dementia symptoms but the concomitant stigma such as fears of being considered abnormal. This issue has rarely been discussed in HRI. Second, we suggest slow communication as an important robot design feature. When robots can wait for PwDs to proceed with information without judging PwDs' relatively slow response, PwDs feel respected and less stigmatized. Third, we address the importance of paying attention to disagreements between PwDs and CPs about robot design preferences. Considering the interdependency of the two parties, robot design processes should allow the two to negotiate.
