Patient perspective on observation methods used in seclusion room in an Irish forensic mental health setting: A qualitative study.

WHAT IS KNOWN ON THE SUBJECT?: Nurses' observation of patients in seclusion is essential to ensure patient safety. Patient observation in seclusion assists nurses in adhering to the requirements of mental health legislation and hospital policy. Direct observation and video monitoring are widely used in observing patients in seclusion. Coercive practices may cause distress to patient-staff relations. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: We add detailed information on specific observation methods in seclusion and compare them from the perspective of patients. Nurses communicating with patients ensures relational contact and that quality care is provided to patients even in the most distressed phase of their illness. Providing prior information to patients on observation methods in seclusion and the need for engaging patients in meaningful activities, while in seclusion are emphasized. Observation via camera and nurses' presence near the seclusion room made patients feel safe and gave a sense of being cared for in seclusion. Pixellating the video camera would give a sense of privacy and dignity. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The overarching goal is to prevent seclusion. However, when seclusion is used as a last resort to manage risk to others, it should be done in ways that recognize the human rights of the patient, in ways that are least harmful, and in ways that recognize and cater to patients' unique needs. A consistent approach to relational contact and communication is essential. A care plan must include patient's preferred approach for interacting while in seclusion to support individualized care provision. Viewing panels (small window on the seclusion door) are important in establishing two-way communication with the patient. Educating nurses to utilize them correctly helps stimulate relational contact and communication during seclusion to benefit patients. Engaging patients in meaningful activities when in seclusion is essential to keep them connected to the outside world. Depending on the patient's presentation in the seclusion room and their preferences for interactions, reading newspapers, poems, stories, or a book chapter aloud to patients, via the viewing panel could help ensure such connectedness. More focus should be placed on providing communication training to nurses to strengthen their communication skills in caring for individuals in challenging care situations. Patient education is paramount. Providing prior information to patients using a co-produced information leaflet might reduce their anxiety and make them feel safe in the room. When using cameras in the seclusion room, these should be pixelated to maintain patients' privacy. ABSTRACT: Introduction A lack of research investigating the specific role that various observational techniques may have in shaping the therapeutic relations in mental health care during seclusion warranted this study. Aim The aim of the study was to explore patients' experience of different methods of observation used while the patient was in seclusion. Method A retrospective phenomenological approach, using semi-structured interviews, ten patients' experiences of being observed in the seclusion room was investigated. Colaizzi's descriptive phenomenological method was followed to analyse the data. Results Communicating and engaging patients in meaningful activities can be achieved via the viewing panel. The camera was considered essential in monitoring behaviour and promoting a sense of safety. Pixelating the camera may transform patient view on privacy in seclusion. Discussion The mental health services must strive to prevent seclusion and every effort should be made to recognise the human rights of the patient. The study reveals numerous advantages when nurses actively engage in patient communication during the process of observation. Implications for Practice Different observation methods yield different benefits; therefore, staff education in using these methods is paramount. Empowering the patient with prior information on seclusion, engaging them in meaningful activities and proper documentation on patient engagement, supports the provision of individualised care in seclusion.

Rab7a activation promotes degradation of select tight junction proteins at the blood-brain barrier after ischemic stroke.

The stability of tight junctions (TJs) between endothelial cells (ECs) is essential to maintain blood-brain barrier (BBB) function in the healthy brain. Following ischemic stroke, TJ strand dismantlement due to protein degradation leads to BBB dysfunction, yet the mechanisms driving this process are poorly understood. Here, we show that endothelial-specific ablation of Rab7a, a small GTPase that regulates endolysosomal protein degradation, reduces stroke-induced TJ strand disassembly resulting in decreased paracellular BBB permeability and improved neuronal outcomes. Two pro-inflammatory cytokines, TNFα and IL1ß, but not glucose and oxygen deprivation, induce Rab7a activation via Ccz1 in brain ECs in vitro, leading to increased TJ protein degradation and impaired paracellular barrier function. Silencing Rab7a in brain ECs in vitro reduces cytokine-driven endothelial barrier dysfunction by suppressing degradation of a key BBB TJ protein, Claudin-5. Thus, Rab7a activation by inflammatory cytokines promotes degradation of select TJ proteins leading to BBB dysfunction after ischemic stroke.

The age-dependent immune response to ischemic stroke.

Stroke is a devastating cause of global morbidity and mortality. Ischemic brain injury triggers a profound local and systemic immune response that participates in stroke pathophysiology. In turn, this immune response has emerged as a potential therapeutic target. In order to maximize its therapeutic potential, it is critical to understand how the immune response to ischemic brain injury is affected by age - the strongest non-modifiable risk factor for stroke. The development of multi-omics and single-cell technologies has provided a more comprehensive characterization of transcriptional and cellular changes that occur during aging. In this review, we summarize recent advances in our understanding of how age-related immune alterations shape differential stroke outcomes in older versus younger organisms, highlighting studies in both experimental mouse models and patient cohorts. Wherever possible, we emphasize outstanding questions that present important avenues for future investigation with therapeutic value for the aging population.

Neurovascular dynamics of repeated cortical spreading depolarizations after acute brain injury.

Cortical spreading depolarizations (CSDs) are increasingly suspected to play an exacerbating role in a range of acute brain injuries, including stroke, possibly through their interactions with cortical blood flow. We use simultaneous wide-field imaging of neural activity and hemodynamics in Thy1-GCaMP6f mice to explore the neurovascular dynamics of CSDs during and following Rose Bengal-mediated photothrombosis. CSDs are observed in all mice as slow-moving waves of GCaMP fluorescence extending far beyond the photothrombotic area. Initial CSDs are accompanied by profound vasoconstriction and leave residual oligemia and ischemia in their wake. Later, CSDs evoke variable responses, from constriction to biphasic to vasodilation. However, CSD-evoked vasoconstriction is found to be more likely during rapid, high-amplitude CSDs in regions with stronger oligemia and ischemia, which, in turn, worsens after each repeated CSD. This feedback loop may explain the variable but potentially devastating effects of CSDs in the context of acute brain injury.

Obesity is independently associated with septic shock, renal complications, and mortality in a multiracial patient cohort hospitalized with COVID-19.

BACKGROUND: Obesity has emerged as a risk factor for severe coronavirus disease 2019 (COVID-19) infection. To inform treatment considerations the relationship between obesity and COVID-19 complications and the influence of race, ethnicity, and socioeconomic factors deserves continued attention. OBJECTIVE: To determine if obesity is an independent risk factor for severe COVID-19 complications and mortality and examine the relationship between BMI, race, ethnicity, distressed community index and COVID-19 complications and mortality. METHODS: A retrospective cohort study of 1,019 SARS-CoV-2 positive adult admitted to an academic medical center (n = 928) and its affiliated community hospital (n-91) in New York City from March 1 to April 18, 2020. RESULTS: Median age was 64 years (IQR 52-75), 58.7% were men, 23.0% were Black, and 52.8% were Hispanic. The prevalence of overweight and obesity was 75.2%; median BMI was 28.5 kg/m2 (25.1-33.0). Over the study period 23.7% patients died, 27.3% required invasive mechanical ventilation, 22.7% developed septic shock, and 9.1% required renal replacement therapy (RRT). In the multivariable logistic regression model, BMI was associated with complications including intubation (Odds Ratio [OR]1.03, 95% Confidence Interval [CI]1.01-1.05), septic shock (OR 1.04, CI 1.01-1.06), and RRT (OR1.07, CI 1.04-1.10), and mortality (OR 1.04, CI 1.01-1.06). The odds of death were highest among those with BMI ≥ 40 kg/m2 (OR 2.05, CI 1.04-4.04). Mortality did not differ by race, ethnicity, or socioeconomic distress score, though Black and Asian patients were more likely to require RRT. CONCLUSIONS AND RELEVANCE: Severe complications of COVID-19 and death are more likely in patients with obesity, independent of age and comorbidities. While race, ethnicity, and socioeconomic status did not impact COVID-19 related mortality, Black and Asian patients were more likely to require RRT. The presence of obesity, and in some instances race, should inform resource allocation and risk stratification in patients hospitalized with COVID-19.

Measuring Community Integration: Development and Psychometrics of the Community Connections and Engagement Scale.

The objective of this community-based participatory research project was to develop a clinically useful, psychometrically-sound scale to measure community integration for adults with severe mental illness. Two researchers and an administrator of a behavioral health agency (BHA) recruited a group of providers, half with lived-experience of severe mental illness. Through a series of five focus groups, provider participants guided identification of four major domains of community integration and the development of 95 scale items; items and domains were reviewed by three external researchers with subject matter expertise. Initial pilot: BHA providers administered the scale to clients (n = 51) with 19 completing it twice to investigate internal consistency, test-retest reliability, and restricted variance and collinearity of items. Further piloting: providers at two BHAs administered the scale to clients (n = 178) to conduct exploratory factor analysis and analyze internal consistency. After initial pilot, 50 items remained post item reduction for restricted variance and collinearity, with Cronbach's alpha of .95 and test-retest reliability of .90. After a larger pilot, a four-factor solution emerged, aligning conceptually with the four domains as anticipated; 33 items loaded (factor loadings ≥ .4), with RMSEA of .069 and overall Cronbach's alpha of .89 (subdomains ranging .78-.86). The scale has good preliminary psychometric properties and appears to be feasible for use in BHAs for the purposes of research and evaluation, with clinical utility for assessment and treatment planning.

Clinical and electrographic features of persistent seizures and status epilepticus associated with anti-NMDA receptor encephalitis (anti-NMDARE).

Based on a multicenter cohort of people with anti-NMDA receptor encephalitis (anti-NMDARE), we describe seizure phenotypes, electroencephalographic (EEG) findings, and anti-seizure treatment strategies. We also investigated whether specific electrographic features are associated with persistent seizures or status epilepticus after acute presentation. In this retrospective cohort study, we reviewed records of children and adults with anti-NMDARE between 2010 and 2014 who were included in the Rare Epilepsy of New York City database, which included the text of physician notes from five academic medical centers. Clinical history (e.g., seizure semiology) and EEG features (e.g., background organization, slowing, epileptiform activity, seizures, sleep architecture, extreme delta brush) were abstracted. We compared clinical features associated with persistent seizures (ongoing seizures after one month from presentation) and status epilepticus, using bivariate and multivariable analyses. Among the 38 individuals with definite anti-NMDARE, 32 (84%) had seizures and 29 (76%) had seizures captured on EEG. Electrographic-only seizures were identified in five (13%) individuals. Seizures started at a median of four days after initial symptoms (IQR: 3-6 days). Frontal lobe-onset focal seizures were most common (n=12; 32%). Most individuals (31/38; 82%) were refractory to anti-seizure medications. Status epilepticus was associated with younger age (15 years [9-20] vs. 23 years [18-27]; p=0.04) and Hispanic ethnicity (30 [80%] vs. 8 [36%]; p=0.04). Persistent seizures (ongoing seizures after one month from presentation) were associated with younger age (nine years [3-14] vs. 22 years [15-28]; p<0.01). Measured electrographic features were not associated with persistent seizures. Seizures associated with anti-NMDARE are primarily focal seizures originating in the frontal lobes. Younger patients may be at increased risk of epileptogenesis and status epilepticus. Continuous EEG monitoring helps identify subclinical seizures, but specific EEG findings may not predict the severity or persistence of seizures during hospitalization.

Circadian and circannual timescales interact to generate seasonal changes in immune function.

Annual changes in day length enhance or suppress diverse aspects of immune function, giving rise to seasonal cycles of illness and mortality. The daily light-dark cycle also entrains circadian rhythms in immunity. Most published reports on immunological seasonality rely on measurements or interventions performed only at one point in the day. Because there can be no perfect matching of circadian phase across photoperiods of different duration, the manner in which these timescales interact to affect immunity is not understood. We examined whether photoperiodic changes in immune function reflect phenotypic changes that persist throughout the daily cycle, or merely reflect photoperiodic shifts in the circadian phase alignment of immunological rhythms. Diurnal rhythms in blood leukocyte trafficking, infection induced sickness responses, and delayed-type hypersensitivity skin inflammatory responses were examined at high-frequency sampling intervals (every 3 h) in Siberian hamsters (Phodopus sungorus) following immunological adaptation to summer or winter photoperiods. Photoperiod profoundly enhanced or suppressed immune function, in a trait-specific manner, and we were unable to identify a phase alignment of diurnal waveforms which eliminated these enhancing and suppressing effects of photoperiod. These results support the hypothesis that seasonal timescales affect immunity via mechanisms independent of circadian entrainment of the immunological circadian waveform.

Endobronchial valve deployment in severe α-1 antitrypsin deficiency emphysema: a case series.

INTRODUCTION: Patients with end-stage emphysema because of α-1 antitrypsin (AAT) deficiency represent a challenging clinical management problem, and studies of volume reduction therapy to date have largely excluded these patients. We report the outcome of bronchoscopic volume reduction with the insertion of Emphasys endobronchial valves (Emphasys Medical, Redwood City, CA, USA) in six patients with end-stage emphysema because of AAT deficiency. CASE SERIES: Of 51 patients with end stage emphysema referred for transplantation, we studied six patients with AAT deficiency and utilized the BODE index and lung allocation score for survival estimation. MEASUREMENTS AND MAIN RESULTS: The forced expiratory volume in 1s improved from a median of 0.575L to 0.905L (P=0.028). There was a median reduction in total lung capacity (TLC) of 0.61L. The residual volume /TLC fell from 74.0% to 58.4%. Before treatment, four patients had a BODE index of greater than eight units, which correlates with a 4-year survival of 18%. After treatment, two patients improved their BODE index to below seven units, which correlates with an estimated 4-year survival of over 50%. CONCLUSIONS: The data from this case series suggest that this intervention may provide bridging therapy to subsequent transplantation for younger AAT patients with end-stage emphysema.

Efficacy and safety of statin therapy in children with familial hypercholesterolemia: a randomized, double-blind, placebo-controlled trial with simvastatin.

BACKGROUND: A multicenter, randomized, double-blind, placebo-controlled study was conducted to evaluate LDL cholesterol-lowering efficacy, overall safety, and tolerability and the influence on growth and pubertal development of simvastatin in a large cohort of boys and girls with heterozygous familial hypercholesterolemia (heFH). METHODS AND RESULTS: A total of 173 heFH children (98 boys and 75 girls) were included in this study. After a 4-week diet/placebo run-in period, children with heFH were randomized to either simvastatin or placebo in a ratio of 3:2. Simvastatin was started at 10 mg/d and titrated at 8-week intervals to 20 and then 40 mg/d. During a 24-week extension period, the patients continued to receive simvastatin (40 mg) or placebo according to their assignment. After 48 weeks of simvastatin therapy, there were significant reductions of LDL cholesterol (-41%), total cholesterol (-31%), apolipoprotein B (-34%), VLDL cholesterol (-21%), and triglyceride (-9%) levels. HDL cholesterol and apolipoprotein A-I levels were increased by 3.3% and 10.4%, respectively (not significant). No safety issues became evident. Except for small decreases in dehydroepiandrosterone sulfate compared with placebo, there were no significant changes from baseline in adrenal, gonadal, and pituitary hormones in either treatment group. CONCLUSIONS: Simvastatin significantly reduced LDL cholesterol, total cholesterol, triglyceride, VLDL cholesterol, and apolipoprotein B levels and was well tolerated in children with heFH. There was no evidence of any adverse effect of simvastatin on growth and pubertal development. Therefore, simvastatin at doses up to 40 mg is a well-tolerated and effective therapy for heFH children.
