Background
The impact of the coronavirus disease 2019 (COVID-19) pandemic on mental health is still being unravelled. It is important to identify which individuals are at greatest risk of worsening symptoms. This study aimed to examine changes in depression, anxiety and post-traumatic stress disorder (PTSD) symptoms using prospective and retrospective symptom change assessments, and to find and examine the effect of key risk factors.
MethodOnline questionnaires were administered to 34 465 individuals (aged 16 years or above) in April/May 2020 in the UK, recruited from existing cohorts or via social media. Around one-third (n = 12 718) of included participants had prior diagnoses of depression or anxiety and had completed pre-pandemic mental health assessments (between September 2018 and February 2020), allowing prospective investigation of symptom change.
ResultsProspective symptom analyses showed small decreases in depression (PHQ-9: −0.43 points) and anxiety [generalised anxiety disorder scale – 7 items (GAD)-7: −0.33 points] and increases in PTSD (PCL-6: 0.22 points). Conversely, retrospective symptom analyses demonstrated significant large increases (PHQ-9: 2.40; GAD-7 = 1.97), with 55% reported worsening mental health since the beginning of the pandemic on a global change rating. Across both prospective and retrospective measures of symptom change, worsening depression, anxiety and PTSD symptoms were associated with prior mental health diagnoses, female gender, young age and unemployed/student status.
ConclusionsWe highlight the effect of prior mental health diagnoses on worsening mental health during the pandemic and confirm previously reported sociodemographic risk factors. Discrepancies between prospective and retrospective measures of changes in mental health may be related to recall bias-related underestimation of prior symptom severity.

Background
Functional neurological disorder (FND), previously known as conversion disorder, is common and often results in substantial distress and disability. Previous research lacks large sample sizes and clinical surveys are most commonly derived from neurological settings, limiting our understanding of the disorder and its associations in other contexts. We sought to address this by analysing a large anonymised electronic psychiatric health record dataset.
MethodsData were obtained from 322 patients in the South London and Maudsley NHS Foundation Trust (SLaM) who had an ICD-10 diagnosis of motor FND (mFND) (limb weakness or disorders of movement or gait) between 1 January 2006 and 31 December 2016. Data were collected on a range of socio-demographic and clinical factors and compared to 644 psychiatric control patients from the same register.
ResultsWeakness was the most commonly occurring functional symptom. mFND patients were more likely to be female, British, married, employed pre-morbidly, to have a carer and a physical health condition, but less likely to have had an inpatient psychiatric admission or to receive benefits. No differences in self-reported sexual or physical abuse rates were observed between groups, although mFND patients were more likely to experience life events linked to inter-personal difficulties.
ConclusionsmFND patients have distinct demographic characteristics compared with psychiatric controls. Experiences of abuse appear to be equally prevalent across psychiatric patient groups. This study establishes the socio-demographic and life experience profile of this understudied patient group and may be used to guide future therapeutic interventions designed specifically for mFND.

Summary
INTRODUCTION
Although Saturn's broad A, B, and C rings epitomize the concept of “planetary rings” in the minds of most people, much of our detailed knowledge of ring dynamics has come from the investigation of smaller-scale features such as density and bending waves, the numerous narrow gaps and their embedded ringlets, and the sharp edges which often demarcate various ring regions. In the case of Uranus, almost all of the ring mass is in the form of narrow rings. Narrow ringlets and gaps, and their associated sharp edges (including those of broad rings) form the subject of this chapter, along with the dynamical theories their study has spawned and the puzzles that continue to surround them.
Examples of several narrow gaps and ringlets in Saturn's rings, as well as the very prominent sharp outer edge of the B ring, are shown in Figure 11.1, from French et al. (2016b). Here one can see a total of eight narrow gaps in the region known as the Cassini Division, ranging in width from 5 km to 360 km, as well as four narrow ringlets. At least six more narrow gaps are found in the outer A ring and in the C ring, while three additional narrow ringlets occur in the C ring. The present chapter will cover all of these features, as well as the ten narrow Uranian rings. Recently a pair of narrow, dense rings has been discovered around the centaur object, Chariklo (Braga-Ribas et al., 2014). These are discussed separately in Chapter 7. We also do not discuss the more tenuous and dusty Jovian and Neptunian ring systems, nor the dusty ringlets found at Saturn and Uranus, all of which are covered in Chapter 12. The complex and unique F ring is described in Chapter 13.
We begin with a short overview of the relevant observations and their limitations in Section 11.2, before reviewing the kinematics, systematic width variations and internal structure of narrow ringlets in Section 11.3. In Section 11.4 we discuss the gaps in Saturn's rings, including searches for any embedded satellites. Section 11.5 deals with individual ringlet and gap edges, especially those that are controlled by resonances with external satellites and those that show evidence for local perturbations by unseen, embedded objects.

Introduction
Rapid exposure of a trauma patient is an essential component of the primary survey. No gold standard exists regarding the best technique to remove clothing from a trauma patient. The purpose of this study is to compare two techniques of clothing removal versus usual practice using standard trauma shears.
MethodsAdvanced Care Paramedic (ACP) students were randomized to either the Cut and Rip (CAR) or Cut Alone (CAL) techniques to remove clothing from a standardized trauma mannequin. Practicing paramedics were recruited to remove clothing from the mannequin using Usual Practice (UP). Total time and time for removal of individual pieces of clothing was recorded.
ResultsTwenty-four participants (8 per group) were recruited to participate. The student groups (CAR, CAL) were similar in mean age (29, 27), years of practice (1 student >5 years) and male gender (63, 43%). The UP group was older (mean 34), more experienced (63% practice >5 years), and had a higher level of training (63% ACP) but a similar percentage of males (63%). Removal time was significantly less in the CAR group compared to the CAL group (mean 104 seconds, 95% CI 88–120 vs. mean 136 seconds, 95% CI 119–154, p=0.02). Removal times in the UP group were not significantly different from the other groups (mean 124 seconds, 95% CI 108–140, p>0.05).
ConclusionThe CAR technique is faster than both CAL and UP groups to remove clothing from a standard trauma mannequin.

BACKGROUND
Infants and young children are frequently colonized with C. difficile but rarely have symptomatic disease. However, C. difficile testing remains prevalent in this age group.
OBJECTIVETo design a computerized provider order entry (CPOE) alert to decrease testing for C. difficile in young children and infants.
DESIGNAn interventional age-targeted before-after trial with comparison group
SETTINGMonroe Carell Jr. Children’s Hospital at Vanderbilt University, Nashville, Tennessee.
PATIENTSAll children seen in the inpatient or emergency room settings from July 2012 through July 2013 (pre-CPOE alert) and September 2013 through September 2014 (post-CPOE alert)
INTERVENTIONIn August of 2013, we implemented a CPOE alert advising against testing in infants and young children based on the American Academy of Pediatrics recommendations with an optional override. We further offered healthcare providers educational seminars regarding recommended C. difficile testing.
RESULTSThe average monthly testing rate significantly decreased after the CPOE alert for children 0–11 months old (11.5 pre-alert vs 0 post-alert per 10,000 patient days; P<.001) and 12–35 months old (61.6 pre-alert vs 30.1 post-alert per 10,000 patients days; P<.001), but not for those children ≥36 months old (50.9 pre-alert vs 46.4 post-alert per 10,000 patient days; P=.3) who were not targeted with a CPOE alert. There were no complications in those children who testing positive for C. difficile.
CONCLUSIONSThe average monthly testing rate for C. difficile for children <35 months old decreased without complication after the use of a CPOE alert in those who tested positive for C. difficile.

The approach and landing of a transport aircraft is a complex operation over which the pilot has only limited control. Although the efficiency of the crew and the serviceability of the aircraft and its systems are to a considerable extent within the command of the pilot, the standards of air traffic control, the availability of navigational aids and the runway length and lighting are beyond his immediate influence. Letdowns with imperfect air traffic control and limited precision aids, particularly if complicated by adverse meteorological conditions, lead to very high workloads which the pilot may find difficult to assimilate. Under these circumstances difficulties may arise during the approach and landing.

Williams LJ, Pasco JA, Jacka FN, Henry MJ, Dodd S, Nicholson GC, Kotowicz MA, Berk M. Bipolar disorder and adiposity: a study using whole body dual energy X-ray absorptiometry scans.
Objective: Previous research has demonstrated a relationship between adiposity and bipolar disorder, although data are derived predominantly from patient samples and use indirect methods of assessing adiposity. This study investigated the association between bipolar disorder and several indices of adiposity, including body fat mass as measured by dual energy X-ray absorptiometry (DXA), in a community-based sample.
Methods: In this study, 21 women with bipolar disorder and 523 healthy controls were drawn from an age-stratified, random, community-based sample of women (20–93 years) participating in the Geelong Osteoporosis Study. Bipolar disorder was diagnosed utilising a semi-structured clinical interview. Anthropometric measurements (weight, height, waist and hip circumference) were taken and fat mass was determined from whole body DXA scans (Lunar DPX-L).
Results Those with bipolar disorder tended to have greater adiposity. Age-adjusted mean (95% CI) values for bipolar versus controls according to adiposity indices were weight 75.6 (68.9–82.3) versus 72.6 (71.3–74.0) kg, waist circumference 89.8 (84.1–95.6) versus 87.3 (86.1–88.5) cm, waist:hip ratio 0.85 (0.82–0.87) versus 0.84 (0.83–0.84), body mass index 27.6 (25.1–30.1) versus 27.5 (27.0–28.0) kg/m2, fat mass 31.4 (26.5–36.3) versus 28.6 (27.5–29.5) kg and %body fat 40.4 (36.9–43.9) versus 38.0 (37.3–38.7)%; all p > 0.05. Further adjustment for height, smoking, alcohol, psychotropic medication, energy intake or physical activity did not influence these patterns.
Conclusion Although a pattern suggestive of greater adiposity among those with bipolar disorder was observed, no significant differences were detected. We cannot exclude the possibility of a type II error. Further research with a larger sample may produce more conclusive results.

Anastomosis of the ascending aorta to the right pulmonary artery, the so-called Waterston shunt, was undertaken as a palliative procedure for children with cyanotic congenital heart disease due to obstruction of the pulmonary outflow tract with reduced pulmonary blood flow. We present the clinico-pathological correlations in two patients who underwent construction of Waterston shunts as neonates, and subsequently died of ruptured pulmonary aneurysms in adult life. Rupture should, therefore, be recognized as a late complication of this procedure, and be considered in the long-term follow-up of such patients, especially when the shunted lung is hypertensive.

Background
Epidemiological evidence supports a relationship between vitamin D and mental well-being, although evidence from large-scale placebo-controlled intervention trials is lacking.
AimsTo examine if vitamin D supplementation has a beneficial effect on mood in community-dwelling older women; if a single annual large dose of vitamin D has a role in the prevention of depressive symptoms; and if there is an association between serum 25-hydroxyvitamin D levels and mental health.
MethodA double-blind, randomised, placebo-controlled trial of women aged 70 or older (the Vital D Study: ISRCTN83409867 and ACTR12605000658617). Participants were randomly assigned to receive 500 000 IU vitamin D3 (cholecalciferol) orally or placebo every autumn/winter for 3–5 consecutive years. The tools utilised at various time points were the General Health Questionnaire, the 12-item Short Form Health Survey, the Patient Global Impression–Improvement scale and the WHO Well-Being Index. Serum 25-hydroxyvitamin D levels were measured in a subset of 102 participants.
ResultsIn this non-clinical population, no significant differences between the vitamin D and placebo groups were detected in any of the measured outcomes of mental health. Serum 25-hydroxyvitamin D levels in the vitamin D group were 41% higher than the placebo group 12 months following their annual dose. Despite this difference, scores from the questionnaires did not differ. Furthermore, there was no interaction between those on antidepressant/anxiety medication at baseline and the treatment groups.
ConclusionsThe lack of improvement in indices of mental well-being in the vitamin D group does not support the hypothesis that an annual high dose of vitamin D3 is a practical intervention to prevent depressive symptoms in older community-dwelling women.

Background
Although there is cross-sectional evidence that changes in the immune system contribute to the pathophysiology of depression, longitudinal data capable of elucidating cause and effect relationships are lacking.
AimsWe aimed to determine whether subclinical systemic inflammation, as measured by serum high-sensitivity C-reactive protein (hsCRP) concentration, is associated with an increased risk of de novo major depressive disorder.
MethodMajor depressive disorder was diagnosed using a clinical interview (SCID–I/NP). This is a retrospective cohort study; from a population-based sample of 1494 randomly selected women recruited at baseline during the period 1994–7, 822 were followed for a decade and provided measures of both exposure and outcome. Of these women, 644 (aged 20–84 years) had no prior history of depression at baseline and were eligible for analysis.
ResultsDuring 5827 person-years of follow-up, 48 cases of de novo major depressive disorder were identified. The hazard ratio (HR) for depression increased by 44% for each standard deviation increase in log-transformed hsCRP (ln-hsCRP) (HR = 1.44, 95% CI 1.04–1.99), after adjusting for weight, smoking and use of non-steroidal anti-inflammatory drugs. Further adjustment for other lifestyle factors, medications and comorbidity failed to explain the observed increased risk for depression.
ConclusionsSerum hsCRP is an independent risk marker for de novo major depressive disorder in women. This supports an aetiological role for inflammatory activity in the pathophysiology of depression.

Background: Regular physical activity is generally associated with psychological well-being, although there are relatively few prospective studies in older adults. We investigated habitual physical activity as a risk factor for de novo depressive and anxiety disorders in older men and women from the general population.
Methods: In this nested case-control study, subjects aged 60 years or more were identified from randomly selected cohorts being followed prospectively in the Geelong Osteoporosis Study. Cases were individuals with incident depressive or anxiety disorders, diagnosed using the Structured Clinical Interview for DSM-IV-TR (SCID-I/NP); controls had no history of these disorders. Habitual physical activity, measured using a validated questionnaire, and other exposures were documented at baseline, approximately four years prior to psychiatric interviews. Those with depressive or anxiety disorders that pre-dated baseline were excluded.
Results: Of 547 eligible subjects, 14 developed de novo depressive or anxiety disorders and were classified as cases; 533 controls remained free of disease. Physical activity was protective against the likelihood of depressive and anxiety disorders; OR = 0.55 (95% CI 0.32–0.94), p = 0.03; each standard deviation increase in the transformed physical activity score was associated with an approximate halving in the likelihood of developing depressive or anxiety disorders. Leisure-time physical activity contributed substantially to the overall physical activity score. Age, gender, smoking, alcohol consumption, weight and socioeconomic status did not substantially confound the association.
Conclusion: This study provides evidence consistent with the notion that higher levels of habitual physical activity are protective against the subsequent risk of development of de novo depressive and anxiety disorders.

Spawning and post-gastrula development of planula larvae of the ahermatype Caryophyllia smithi are described. Gametes develop within the mesenteries of the adults usually between January and March, are discharged through the mouth of the polyp and fertilized externally in the sea water. Ova are either brown or cream in colour, spherical or slightly oval in shape and are 130–150 µm in diameter. Planulae are fully formed after 48 h, when feeding commences. A large apical tuft (30–60 µm in length) is present but only during the first six weeks of pelagic life. After 8–10 weeks of feeding in culture larvae reach a length of 800–1000 µm: they are then fully developed and ready to settle. Attention is paid to the effects of sea water temperatures on reproduction; locomotion and feeding behaviour of planulae are also discussed.

Background
Smoking is disproportionately prevalent among people with psychiatric illness.
AimsTo investigate smoking as a risk factor for major depressive disorder.
MethodA population-based sample of women was studied using case–control and retrospective cohort study designs. Exposure to smoking was self-reported, and major depressive disorder diagnosed using the Structured Clinical Interview for DSM–IV–TR (SCID–I/NP).
ResultsAmong 165 people with major depressive disorder and 806 controls, smoking was associated with increased odds for major depressive disorder (age-adjusted odds ratio (OR)=1.46, 95% CI 1.03–2.07). Compared with non-smokers, odds for major depressive disorder more than doubled for heavy smokers (>20 cigarettes/day). Among 671 women with no history of major depressive disorder at baseline, 13 of 87 smokers and 38 of 584 non-smokers developed de novo major depressive disorder during a decade of follow-up. Smoking increased major depressive disorder risk by 93% (hazard ratio (HR)=1.93, 95% CI 1.02–3.69); this was not explained by physical activity or alcohol consumption.
ConclusionsEvidence from cross-sectional and longitudinal data suggests that smoking increases the risk of major depressive disorder in women.

The effectiveness of influenza vaccination in reducing hospitalization of people with diabetes for influenza, pneumonia, or diabetic events during influenza epidemics was assessed in a case control study in Leicestershire, England. Cases were 80 patients on the Leicestershire Diabetes Register who were admitted and discharged from hospital with International Classification of Disease codes for pneumonia, bronchitis, influenza, diabetic ketoacidosis, coma and diabetes, without mention of complications, during the influenza epidemics of 1989–90 and 1993. One hundred and sixty-controls, who were not admitted to hospital during this period, were randomly selected from the Register. Immunization against influenza was assessed in 37 cases and 77 controls for whom consent was obtained to access their clinical notes and for whom notes were available. Significant association was detected between reduction in hospitalization and influenza vaccination during the period immediately preceding an epidemic. Multiple logistic regression analysis estimated that influenza vaccination reduced hospital admissions by 79% (95% CI 19–95%) during the two epidemics, after adjustment for potential confounders.

Tungsten and silicon carbide fibres have been coated with diamond using the HFCVD technique. The diamond volume fraction varied between 26% and 73%. Resonance in bending tests gave a Young's modulus of 880 GPa for the diamond coating. Tensile testing indicated that the diamond fracture strength was between 600 MPa and 2000 MPa, depending on the coating thickness, and thus the grain size, of the diamond. The strain to failure of the diamond coating in bending was approximately 0.15% for 25 μm thick films.

We present an overview of the locally self-consistent multiple scattering (LSMS) method. The method is based on real space multiple scattering theory, is naturally highly parallel, and has been implemented on Intel Paragon parallel platforms within the Center for Computational Sciences at Oak Ridge National Laboratory. O(N)-scaling is demonstrated for unit cells as large as 1000-atoms. We discuss in detail how the real space convergence properties of the method can be controlled by taking advantage of the stationary properties of a finite temperature Harris-Foulkes free energy functional. We show how the LSMS method can be combined with spin-dynamics to treat non-collinear magnetic states of materials. We show some preliminary results for the ground state magnetic structure of FCC Fe0.6 5Ni 0.35 alloys that indicate the possible existence of non-collinear arranges of magnetic moments in this system.
