Telemedicine’s payment and regulatory structures, licensing, credentialing, and implementation take time to work through, but health systems that have already invested in telemedicine are well ...positioned to ensure that patients with Covid-19 receive the care they need.
In response to the emerging crisis and growing calls from patients and clinicians for guidance 5, a working group of clinical experts from the International College of Obsessive Compulsive Spectrum ...Disorders (ICOCS) and the Obsessive-Compulsive and Related Disorders Research Network of the European College of Neuropsychopharmacology (OCRN) have produced this consensus statement with the aim of delivering pragmatic guidance at the earliest opportunity to clinicians for managing this complex challenge. Based on the risks associated with exposure and response prevention (ERP) in the pandemic (see below), and uncertainty as to which of the two evidence-based treatments, pharmacotherapy or cognitive behaviour therapy (CBT), represents the most efficacious first line treatment modality 11, pharmacotherapy should be the first option for adults and children with OCD with contamination, washing or cleaning symptoms during the COVID-19 pandemic. Consider A) type of medication; most patients should receive an SSRI, or if not responsive, another SSRI and as a third choice clomipramine (for which an ECG may be required in certain patient groups); Note US Food and Drug Administration "black box" warnings or advice from equivalent national regulatory authorities regarding increased risk in young people and other vulnerable patient groups. Check for adverse effects and be available for any concerns related to "activation" or newly emergent or increased suicidal ideation, which in the young can be mitigated by starting treatment at a low dose and titrating more gradually; B) dosage; if the patient is on a suboptimal dose, consider increasing it, paying attention to any contraindications; C) SSRI-resistance; consider a low dose of adjunctive antipsychotic (aripiprazole, risperidone, quetiapine, olanzapine), especially if a tic is present; D) adherence; ensure the patient is able to obtain an adequate supply and is taking the treatment regularly.
In this paper, we investigate the nonlinear interaction and time-evolution of confined optical, thermal and mechanical modes in a three-dimensional optomechanical resonator. We model a high-finesse ...cavity with a thin thermo-elastic panel placed at the center of two highly reflective mirrors that is subjected to an incoming continuous-wave electromagnetic field. The latter is constructed by constraining the light-structure interaction to a first-order scattering phenomenon in the classical interpretation modeled as a spatio-temporal perturbation around a time-harmonic field. We employ a Galerkin-based separation of variables decomposition on the resultant fields and replace them with their nonlinear modal counterparts. The resulting dynamical system is thus governed by the combined effects of thermal and radiation stresses which yield a complex spatially dependent self-excited bifurcation structure where Hopf bifurcations give rise to periodic limit-cycle solutions. In regions where coexisting solutions are found, homoclinic connections ensue codimension-two Bogdanov–Takens and Double-Hopf bifurcations and that for a range of control parameters a global homoclinic Shilnikov bifurcation culminates with a distinct period-doubling route to chaos. We note that the current formulation demonstrates the essential contribution of coupled thermal and radiation stresses to the bifurcation structure of nonlinear light-structure interaction systems and may shed light to modal energy transfer mechanisms and scattering phenomena.
Study objective We study the impact of emergency department (ED) crowding on delays in treatment and nontreatment for patients with severe pain. Methods We performed a retrospective cohort study of ...all patients presenting with severe pain to an inner-city, teaching ED during 17 months. Poor care was defined by 3 outcomes: not receiving treatment with pain medication while in the ED, a delay (>1 hour) from triage to first pain medication, and a delay (>1 hour) from room placement to first pain medication. Three validated crowding measures were assigned to each patient at triage. Logistic regression was used to test the association between crowding and outcomes. Results In 13,758 patients with severe pain, the mean age was 39 years (SD 16 years), 73% were black, and 64% were female patients. Half (49%) of the patients received pain medication. Of those treated, 3,965 (59%) experienced delays in treatment from triage and 1,319 (20%) experienced delays from time of room placement. After controlling for factors associated with the ED treatment of pain (race, sex, severity, and older age), nontreatment was independently associated with waiting room number (odds ratio OR 1.03 for each additional waiting patient; 95% confidence interval CI 1.02 to 1.03) and occupancy rate (OR 1.01 for each 10% increase in occupancy; 95% CI 0.99 to 1.04). Increasing waiting room number and occupancy rate also independently predicted delays in pain medication from triage (OR 1.05 for each waiting patient, 95% CI 1.04 to 1.06; OR 1.18 for each 10% increase in occupancy; 95% CI 1.15 to 1.21) and delay in pain medication from room placement (OR 1.02 for each waiting patient, 95% CI 1.01 to 1.03; OR 1.06 for each 10% increase in occupancy, 95% CI 1.04 to 1.08). Conclusion ED crowding is associated with poor quality of care in patients with severe pain, with respect to total lack of treatment and delay until treatment.
OCD is characterized by obsessions (recurrent, intrusive, unwanted thoughts, images or impulses and compulsions (repetitive behaviors or mental acts that the individual feels compelled to perform), ...which can manifest together or separately (Fineberg et al., 2020). NICE guidelines suggest that low intensity psychological treatments (including ERP) is the first line treatment for OCD, and that a “stepped care” treatment approach for OCD reserves combination treatment for adults with OCD with severe functional impairment, and for adults without an adequate response to: 1) treatment with an SSRI alone (12 weeks duration) or 2) CBT (including ERP) alone (NICE, 2005). Existing US treatment guidelines (APA guidelines) suggest that there are three first-line treatments for OCD (SSRI, CBT, SSRI+CBT) and recommends combined treatment for patients with an unsatisfactory response to monotherapy or for patients with severe OCD. Although, systematic review and meta-analysis of studies published in 1993–2014 suggest that combination treatment was not significantly better than CBT plus placebo (Ost et al., 2015), based on data from a recent systematic and meta-analysis which searched the two controlled trials registers maintained by the Cochrane Collaboration Common Mental Disorders group, the combination treatment approach is likely to be more effective than psychotherapeutic interventions alone, at least in severe obsessive-compulsive disorder (Skapinakis et al., 2016a). Based on data from Optimal treatment for OCD study conducted by Fineberg et al., (2018) combined treatment appeared to be the most effective especially when compared to CBT monotherapy, but SSRI monotherapy was found as the most cost effective. In this review we summarize available treatment recommendations.
•This manuscript examines whether or not combination treatment with an SSRI and low intensity psychological treatment (ERP or CBT with or without ERP) is the optimal initial treatment for OCD in comparison to monotherapy treatments (CBT or SSRI).•NICE guidelines suggest that low intensity psychological treatments (including ERP) is the first line treatment for OCD, and that a “stepped care” treatment approach for OCD reserves combination treatment for adults with OCD with severe functional impairment, and for adults without an adequate response to: 1) treatment with an SSRI alone (12 weeks duration) or 2) CBT (including ERP) alone (Fineberg et al., 2020).•NICE guidelines further suggest that more research is needed as to the effect of combination treatment versus single-strand treatments and involve a follow-up of 1, 2 and 5 years (Fineberg et al., 2020).•Questions remain as to whether combination treatment is better for improving treatment response or for disease remission.
The Internet is now all-pervasive across much of the globe. While it has positive uses (e.g. prompt access to information, rapid news dissemination), many individuals develop Problematic Use of the ...Internet (PUI), an umbrella term incorporating a range of repetitive impairing behaviours. The Internet can act as a conduit for, and may contribute to, functionally impairing behaviours including excessive and compulsive video gaming, compulsive sexual behaviour, buying, gambling, streaming or social networks use. There is growing public and National health authority concern about the health and societal costs of PUI across the lifespan. Gaming Disorder is being considered for inclusion as a mental disorder in diagnostic classification systems, and was listed in the ICD-11 version released for consideration by Member States (http://www.who.int/classifications/icd/revision/timeline/en/). More research is needed into disorder definitions, validation of clinical tools, prevalence, clinical parameters, brain-based biology, socio-health-economic impact, and empirically validated intervention and policy approaches. Potential cultural differences in the magnitudes and natures of types and patterns of PUI need to be better understood, to inform optimal health policy and service development. To this end, the EU under Horizon 2020 has launched a new four-year European Cooperation in Science and Technology (COST) Action Programme (CA 16207), bringing together scientists and clinicians from across the fields of impulsive, compulsive, and addictive disorders, to advance networked interdisciplinary research into PUI across Europe and beyond, ultimately seeking to inform regulatory policies and clinical practice. This paper describes nine critical and achievable research priorities identified by the Network, needed in order to advance understanding of PUI, with a view towards identifying vulnerable individuals for early intervention. The network shall enable collaborative research networks, shared multinational databases, multicentre studies and joint publications.
Summary Oxytocin has known stress-reducing and attachment-enhancing effects. We thus hypothesized that oxytocin would attenuate emotional and hormonal responses to stress in borderline personality ...disorder (BPD). Fourteen BPD and 13 healthy control (HC) adults received 40IU intranasal oxytocin or placebo in double-blind randomized order followed by the Trier Social Stress Test. Subjective dysphoria (Profile of Mood Changes) and plasma cortisol levels were measured. Childhood trauma history, attachment style, and self-esteem were also rated. A significant “Group × Drug × Time” interaction effect for dysphoria ( p = .04) reflected a proportionately greater attenuation of stress-induced dysphoria in the BPD group after oxytocin administration. Additionally, a marginally significant “Group × Drug” interaction effect for cortisol ( p = .10) reflected a tendency toward greater attenuation of the stress-induced cortisol surge in the BPD group after oxytocin administration. In the combined sample, the oxytocin-placebo difference in the emotional stress reactivity was significantly predicted by childhood trauma alone ( p = .037) and combined with self-esteem ( p = .030), whereas the oxytocin-placebo difference in cortisol stress reactivity was predicted only by insecure attachment ( p = .013). Results suggest that oxytocin may have a beneficial impact on emotional regulation in BPD, which merits further investigation and could have important treatment implications.
Chimeric antigen receptor (CAR) T cells have shown great success in the treatment of CD19+ hematological malignancies, leading to their recent approval by the FDA as a new cancer treatment modality. ...However, their broad use is limited since a CAR targets a single tumor associated antigen (TAA), which is not effective against tumors with heterogeneous TAA expression or emerging antigen loss variants. Further, stably engineered CAR T cells can continually and uncontrollably proliferate and activate in response to antigen, potentially causing fatal on-target off-tumor toxicity, cytokine release syndrome, or neurotoxicity without a method of control or elimination. To address these issues, our lab and others have developed various universal immune receptors (UIRs) that allow for targeting of multiple TAAs by T cells expressing a single receptor. UIRs function through the binding of an extracellular adapter domain which acts as a bridge between intracellular T cell signaling domains and a soluble tumor antigen targeting ligand (TL). The dissociation of TAA targeting and T cell signaling confers many advantages over standard CAR therapy, such as dose control of T cell effector function, the ability to simultaneously or sequentially target multiple TAAs, and control of immunologic synapse geometry. There are currently four unique UIR platform types: ADCC-mediating Fc-binding immune receptors, bispecific protein engaging immune receptors, natural binding partner immune receptors, and anti-tag CARs. These UIRs all allow for potential benefits over standard CARs, but also bring unique engineering challenges that will have to be addressed to achieve maximal efficacy and safety in the clinic. Still, UIRs present an exciting new avenue for adoptive T cell transfer therapies and could lead to their expanded use in areas which current CAR therapies have failed. Here we review the development of each UIR platform and their unique functional benefits, and detail the potential hurdles that may need to be overcome for continued clinical translation.
The COVID-19 pandemic significantly impacted children's physical activity. Recent evidence indicated children's accelerometer-measured physical activity levels have, on average, returned to near ...pre-pandemic levels in 2022, though sedentary behaviour remains higher. However, insufficient physical activity levels among children continues to be a critical public health issue in the UK, with only 41% meeting physical activity guidelines. This study aimed to provide in-depth analysis of how the pandemic has shaped children's physical activity patterns beyond the short-term periods following lockdowns and identify the new challenges to engaging children in physical activity.
One-to-one interviews with parents (n = 22), school staff (n = 9), and six focus groups with children aged 10-11 years (n = 45) were conducted between February and July 2022. Topics explored changes to children's physical activity and sedentary behaviour patterns, including screen-viewing, and factors influencing any changes. The framework method was used for analysis.
Five themes were generated. Theme 1 described residual lockdown habits, including increased screen-viewing within the home, while activities outside the home continued to feel less spontaneous. Theme 2 highlighted an interrupted development of social, emotional, and physical skills among children compared to what would be expected pre-pandemic. This coincided with Theme 3 which reflected increased mental health challenges among families, creating complex barriers to children's physical activity. A new normal for child physical activity was evoked and explored in Theme 4, with greater dependence on structured and organised activities. However, Theme 5 highlighted that girls and children with lower socio-economic position may be especially at risk of decreased physical activity.
There is a new normal for children's physical activity that is characterised by increased dependence on structured and organised physical activities, such as active clubs, and less on unstructured and spontaneous physical activities, such as physical play. While this may suit many children, girls and children from lower socio-economic households face barriers to participating in the new normal. It is important that affordable and equitable opportunities are provided to all children to prevent physical activity and health inequalities.
