This work presents the results of kinetic measurements for the reactions of atomic bromine with the three isomers of trimethylbenzene at temperatures from 295 K to 354 K and at pressures close to atmospheric. The atomic bromine was produced by photolysis of Br in a thermostated Pyrex chamber as described in our previous work. The reactants were present as dilute mixtures in argon with Br in sufficient excess to scavenge the free radical products of the initiation step.

Posttraumatic stress disorder (PTSD) is a devastating condition, for which there are few pharmacological agents, often with a delayed onset of action and poor efficacy. Trauma-focused psychotherapies are further limited by few trained providers and low patient engagement. This frequently results in disease chronicity as well as psychiatric and medical comorbidity, with considerable negative impact on quality of life.

Wang-Landau simulations offer the possibility to integrate explicitly over a collective coordinate and stochastically over the remainder of configuration space. We propose to choose the so-called "slow mode," which is responsible for large autocorrelation times and thus critical slowing down, for collective integration. We study this proposal for the Ising model and the linear-log-relaxation (LLR) method as simulation algorithm.

Background: Maladaptive therapist schemas are hypothesized to generate difficulties within cognitive behavioural therapy (CBT) practice, training and supervision. Without adequate identification and management, they negatively affect the cognitions and emotions of the therapist, leading them to behave in ways that risk ruptures or therapy and supervision being delivered in a suboptimal fashion. Consequently, there is a need to synthesize the research that has been undertaken to date on the content, prevalence, identification and management of maladaptive therapist schemas.

Background: Men with prostate cancer experience immediate and long-term consequences of the disease and its treatment. They require both long-term monitoring for recurrence or progression and follow-up to identify and help manage psychosocial and physical impacts. Holistic Needs Assessment aims to ensure patient-centered continuing cancer care.

Background: Trauma and chronic stress are believed to induce and exacerbate psychopathology by disrupting glutamate synaptic strength. However, in human methods to estimate synaptic strength are limited. In this study, we established a novel putative biomarker of glutamatergic synaptic strength, termed energy-per-cycle (EPC).

This work reports the temperature dependence of the rate coefficients for the reactions of atomic bromine with the xylenes that are determined experimentally and theoretically. The experiments were carried out in a Pyrex chamber equipped with fluorescent lamps to measure the rate coefficients at temperatures from 295 K to 346 K. Experiments were made at several concentrations of oxygen to assess its potential kinetic role under atmospheric conditions and to validate comparison of our rate coefficients with those obtained by others using air as the diluent.

Background: Our previous study showed that parents with mental health problems or substance abuse are at increased risk of having children removed from the home, primarily due to caregiving deficits, neglect, and prenatal exposure to substances, not physical abuse.

Objective: Using a larger sample and more rigorous analysis, the present study improves and expand upon the previous study, yielding more robust explanations for why these children are at increased risk of removal.

Participants And Setting: The study uses a sample of 4070 Structured Decision Making® assessments conducted by San Francisco's Child Welfare provider involving parents reported for the first time from 2007 to 2015.

Initial child welfare screening decisions, traditionally made by an individual worker, determine if a family will receive further intervention by child protective services. A multi-disciplinary team (MDT) decision-making approach for child welfare referrals aims to provide a more thorough assessment of needs and strengths and to connect families to appropriate community-based providers. This study examined 159 child welfare referrals handled by MDTs compared to 331 referrals handled via the traditional screening approach.

Background: Major depressive disorder (MDD) treatment is characterized by low remission rate and often involves weeks to months of treatment. Identification of pretreatment biomarkers of response may play a critical role in novel drug development, in enhanced prognostic predictions, and perhaps in providing more personalized medicine. Using a network restricted strength predictive modeling (NRS-PM) approach, the goal of the current study was to identify pretreatment functional connectome fingerprints (CFPs) that (1) predict symptom improvement regardless of treatment modality and (2) predict treatment specific improvement.

The endoplasmic reticulum (ER) has emerged as a source of hydrogen peroxide (HO) and a hub for peroxide-based signaling events. Here we outline cellular sources of ER-localized peroxide, including sources within and near the ER. Focusing on three ER-localized proteins-the molecular chaperone BiP, the transmembrane stress-sensor IRE1, and the calcium pump SERCA2-we discuss how post-translational modification of protein cysteines by HO can alter ER activities.

Haploinsufficiency of progranulin (PGRN) is a leading cause of frontotemporal lobar degeneration (FTLD). Loss of PGRN leads to lysosome dysfunction during aging. TMEM106B, a gene encoding a lysosomal membrane protein, is the main risk factor for FTLD with PGRN haploinsufficiency.

Introduction: Rates of adolescent substance use have decreased in recent years. Knowing whether nonmedical marijuana legalization for adults is linked to increases or slows desirable decreases in marijuana and other drug use or pro-marijuana attitudes among teens is of critical interest to inform policy and promote public health. This study tests whether nonmedical marijuana legalization predicts a higher likelihood of teen marijuana, alcohol, or cigarette use or lower perceived harm from marijuana use in a longitudinal sample of youth aged 10-20 years.

More than six decades have passed since the discovery of monoaminergic antidepressants. Yet, it remains a mystery why these drugs take weeks to months to achieve therapeutic effects, although their monoaminergic actions are present rapidly after treatment. In an attempt to solve this mystery, rather than studying the acute neurochemical effects of antidepressants, here we propose focusing on the early changes in the brain functional connectome using traditional statistics and machine learning approaches.

Article Synopsis
  • This study explored a new way to provide prostate cancer care by using an online holistic needs assessment (sHNA) for patients and facilitating digital communication with healthcare professionals (HCPs).
  • Men with prostate cancer participated in a 9-month study where they completed the sHNA multiple times, and their feedback was measured using Patient Reported Outcome Measures (PROMs), focusing on their engagement and experience.
  • Results showed high initial patient engagement and satisfaction with the sHNA, but challenges with integrating hospital and general practice IT systems prevented the care model from functioning as intended, indicating the need for further improvements before larger trials.

Article Synopsis
  • Men prostate cancer survivors experience a range of unmet needs, prompting the development of an online and cancer-specific Holistic Needs Assessment (sHNA) designed to improve service integration within healthcare.
  • A qualitative study was conducted in two phases: the first phase involved interviews with healthcare professionals and patients to gauge perceptions of the sHNA before its implementation, while the second phase assessed barriers and motivators to its use 9 to 12 months post-implementation.
  • Results showed that while both patients and healthcare professionals found the sHNA beneficial, barriers such as confidence levels, organizational changes, and patient-specific factors impacted its use, leading to a focused implementation strategy that included specialized training and peer support.

In the field of prevention science, some consider fidelity to manualized protocols to be a hallmark of successful implementation. A growing number of scholars agree that high-quality implementation should also include some adaptations to local context, particularly as prevention programs are scaled up, in order to strengthen their relevance and increase participant engagement. From this perspective, fidelity and adaptation can both be seen as necessary, albeit mutually exclusive, dimensions of implementation quality.

High-quality implementation is important for preventive intervention effectiveness. Although this implies fidelity to a practice model, some adaptation may be inevitable or even advantageous in routine practice settings. In order to organize the study of adaptation and its effect on intervention outcomes, scholars have proposed various adaptation taxonomies.
