Foreword by Tom Wright CBE, Age UK It is now widely accepted that the mental health needs of older people have historically been under-recognised and under-treated. Although the proportion of those affected is broadly in line with other age groups, older people have not been able to access the same level of support. Research has also found that older people with common mental health conditions are more likely to be on drug therapies and less likely to be in receipt of talking therapies compared to other age groups. Older people themselves may be reluctant to seek help – with fewer than one in six older people with depression ever discussing it with their GP. Later life is a time when getting the right support is extremely important for wellbeing due to the complex challenges older people often face. As our population ages, it is crucial to ensure that older people’s mental health not only attains parity with physical health diagnostics and care, but parity with other age groups too. At Age UK we are committed to addressing the mental health needs of older people so that they can live fulfilling later lives. Over the past few years we have worked with NHS England on a campaign to improve older people’s

Corresponding author: William Winlow Key Words: General anaesthetic, calcium channels, Lymnaea, light yellow cells SUMMARY 1. Using the two electrode voltage clamp configuration, a high voltage activated whole-cell Ca2+ channel current (IBa) was recorded from a cluster of neurosecretory ‘Light Yellow’ Cells (LYC) in the right parietal ganglion of the pond snail Lymnaea stagnalis. 2. Recordings of IBa from LYCs show a reversible concentration-dependent depression of current amplitude in the presence of the volatile anaesthetics halothane, isoflurane and sevoflurane, or the non-volatile anaesthetic pentobarbitone at clinical concentrations. 3. In the presence of the anaesthetics investigated, IBa measured at the end of the depolarizing test pulse showed proportionally greater depression than that at measured peak amplitude, as well as significant decrease in the rate of activation or increase in inactivation or both.

  • Trauma: What Lurks Beneath the Surface
    \\jciprod01\productn\N\NYC\24-2\NYC204.txt unknown Seq: 1 15-MAR-18 13:45 TRAUMA: WHAT LURKS BENEATH THE SURFACE SARA E. GOLD* Scholarship in the behavioral health field demonstrates that an overwhelming majority of clients experiencing urban poverty, and particularly low-income clients living with chronic medical and mental health issues, have endured trauma as children and adults. While legal scholars and service providers have begun to discuss the role that trauma plays in the client’s interactions with the lawyer, the dialogue has largely focused on trauma relevant to the subject matter of the legal representation. This article expands current scholarship by asserting that given the prevalence of trauma, the lawyer serving the urban poor should presumptively adopt a trauma-informed prac- tice approach regardless of the subject matter of the representation. The lawyer engaging in a trauma-informed practice can enrich the client experience generally and enrich it significantly for the many clients who come to the lawyer-client relationship with a history of trauma.

    The VA Office of Patient Centered Care and Cultural Transformation’s and VA Complementary and Integrative Health Evaluation Center’s Library of Research Articles on Veterans and Complementary and Integrative Health Therapies April, 2020 1 Library of Research Articles on Veterans and Complementary and Integrative Health Therapies We are pleased to announce the VA Office of Patient Centered Care and Cultural Transformation’s (OPCC&CT) and VA Complementary and Integrative Health Evaluation Center’s (CIHEC) “Library of Research Articles on Veterans and Complementary and Integrative Health Therapies”. The Library is comprised of two sections: 1) Articles organized by type of CIH therapies, among the nine therapies that the VA considers medical treatments and 2) Articles organized by type of health outcome, among nine outcomes (i.e., pain, anxiety, depression, post-traumatic stress disorder (PTSD), substance/opioid abuse, stress and wellbeing, insomnia, suicide, and Veteran caregiver wellbeing and VA employee wellbeing). The Library provides the citation (with links to either the actual article or to its page in PubMed) as well as the abstract, if available. Although every attempt was made to include all relevant studies conducted, it is possible we missed some and will gladly include additional studies when found. The Library will be updated biannually, with the next update available in June 2020. It can be found at the OPCC&CT website at https://www.va.gov/wholehealth/ and the CIHEC website at https://www.hsrd.research.va.gov/centers/cshiip.cfm.

  • What Are People's Lay Theories About Mind Wandering and How Do Those Beliefs Affect Them?
    What Are People’s Lay Theories About Mind Wandering and How Do Those Beliefs Affect Them? Claire M. Zedelius and Jonathan W. Schooler Many of the thoughts that pass through our minds each day are disconnected from the here and now. While we may seem engaged with our current activity or environment—our eyes scanning a page of text or locking with those of a con- versation partner—our attention is often directed inwardly, to thoughts about cur- rent concerns, future plans, or fantasies. These types of thoughts, studied under the (somewhat interchangeably used) terms stimulus- or task-unrelated thoughts, de- coupled thought, daydreaming, and mind wandering (e.g., Antrobus, 1968; Singer & Schonbar, 1961; Smallwood & Schooler, 2006), are often spontaneous and unsolicited (Seli, Carriere, & Smilek, 2014; Seli, Risko, Smilek, & Schacter, 2016), yet occupy an astonishing 30–50% of our waking life (Kane et al., 2007; Killingsworth & Gilbert, 2010; Klinger & Cox, 1987; McVay, Kane, & Kwapil, 2009), with far-reaching and often negative consequences for our performance (see Mooneyham & Schooler, 2013 for a review), mood (Franklin et al., 2013; Killingsworth & Gilbert, 2010), and safety (e.g., Galera et al., 2012). Sometimes stimulus-unrelated thoughts have an intrusive character. Intrusive thoughts tend to be repetitive and revolve around fears or traumatic events (Clark & Rhyno, 2005). Like normal mind wandering, intrusive thoughts are highly common among healthy individuals (Clark & Rhyno, 2005), but they are also a hallmark feature of a surprising range of disorders, including depression, generalized anxiety disorder, insomnia, obsessive–compulsive disorder (OCD), and posttraumatic stress disorder (PTSD; Clark, 2005; Davies & Clark, 1998).
