How to measure monetary losses in gambling disorder? An evidence-based refinement.

Diverse monetary measures have been utilized across different studies in gambling disorder (GD). However, there are limited evidence-based proposals regarding the best way to assess financial losses. We investigated how different variables of monetary losses correlate with validated assessments of gambling severity and overall functioning in a large sample of subjects with GD (n = 436). We found that relative monetary variables (i.e. when financial losses were evaluated in relation to personal income) showed the most robust correlations with gambling severity and overall psychosocial functioning. Percentage of monthly income lost from gambling was the variable with the best performance. Keywords:Open Access funded by Wellcome Trus

Palliative care making a difference in rural Uganda, Kenya and Malawi: three rapid evaluation field studies

<p>Abstract</p> <p>Background</p> <p>Many people live and die in pain in Africa. We set out to describe patient, family and local community perspectives on the impact of three community based palliative care interventions in sub-Saharan Africa.</p> <p>Methods</p> <p>Three palliative care programmes in Uganda, Kenya and Malawi were studied using rapid evaluation field techniques in each country, triangulating data from three sources: <b><it>interviews </it></b>with key informants, <b><it>observations </it></b>of clinical encounters and the local health and social care context, and routine data from local <b><it>reports and statistics</it></b>.</p> <p>Results</p> <p>We interviewed 33 patients with advanced illness, 27 family carers, 36 staff, 25 volunteers, and 29 community leaders and observed clinical care of 12 patients. In each site, oral morphine was being used effectively. Patients valued being treated with dignity and respect. Being supported at home reduced physical, emotional and financial burden of travel to, and care at health facilities. Practical support and instruction in feeding and bathing patients facilitated good deaths at home.</p> <p>In each country mobile phones enabled rapid access to clinical and social support networks. Staff and volunteers generally reported that caring for the dying in the face of poverty was stressful, but also rewarding, with resilience fostered by having effective analgesia, and community support networks.</p> <p>Conclusions</p> <p>Programmes were reported to be successful because they integrated symptom control with practical and emotional care, education, and spiritual care. Holistic palliative care can be delivered effectively in the face of poverty, but a public health approach is needed to ensure equitable provision.</p

Cold pressor pain in skin picking disorder.

Excoriation (skin-picking) disorder (SPD) is a disabling, under-recognized condition in which individuals repeatedly pick at their skin, leading to noticeable tissue damage. There has been no examination as to whether individuals with SPD have different pain thresholds or pain tolerances compared to healthy counterparts. Adults with SPD were examined on a variety of clinical measures including symptom severity and functioning. All participants underwent the cold pressor test. Heart rate, blood pressure, and self-reported pain were compared between SPD participants (n=14) and healthy controls (n=14). Adults with SPD demonstrated significantly dampened autonomic response to cold pressor pain as exhibited by reduced heart rate compared to controls (group x time interaction using repeated ANOVA F=3.258, p<0.001). There were no significant differences between the groups in terms of overall pain tolerance (measured in seconds), recovery time, or blood pressure. SPD symptom severity was not significantly associated with autonomic response in the patients. In this study, adults with SPD exhibited a dampened autonomic response to pain while reporting pain intensity similar to that reported by the controls. The lack of an autonomic response may explain why the SPD participants continue a behavior that they cognitively find painful and may offer options for future interventions.Dr. Grant has received research grants from NIMH, National Center for Responsible Gaming, the American Foundation for Suicide Prevention, the TLC Foundation for Body Focused Repetitive Behaviors, Brainsway, Forest, Takeda, and Psyadon Pharmaceuticals.

Orientation dependence of ground motion and structural response of reinforced concrete space frames

Horizontal seismic demand is represented in seismic design codes by a single elastic response spectrum. Using a single spectrum conceals the difference between ground motions that are highly polarised and those for which the demand does not depend significantly on the orientation. In this study, two suites of ground motion were developed using the program RspMatchBi, with each suite characterised by different orientation dependence and seismic demand. Reinforced concrete space frames with various arrangements in plan were modelled in OpenSees. Non-linear time history analysis was carried out with the suites of records applied to the models at 9 degree increments, through 360 degrees of non-redundant orientations. An iteration process was implemented to determine the scaling factor for each ground motion at which storey drift exceeded a design level of 2.5% in 50% of applied orientations. Various performance criteria were also taken into account to investigate the changes in orientation dependence of seismic structural response. Results suggest that azimuthdependent structures are more vulnerable to orientation-dependent seismic demand, and that the investigation of directionality for seismic design needs further consideration in terms of performance criteria and structural periods at each principle axis

Resource use data by patient report or hospital records: Do they agree?

Background: Economic evaluations alongside clinical trials are becoming increasingly common. Cost data are often collected through the use of postal questionnaires; however, the accuracy of this method is uncertain. We compared postal questionnaires with hospital records for collecting data on physiotherapy service use. Methods: As part of a randomised trial of orthopaedic medicine compared with orthopaedic surgery we collected physiotherapy use data on a group of patients from retrospective postal questionnaires and from hospital records. Results: 315 patients were referred for physiotherapy. Hospital data on attendances was available for 30% (n = 96), compared with 48% (n = 150) of patients completing questionnaire data (95% Cl for difference = 10% to 24%); 19% (n = 59) had data available from both sources. The two methods produced an intraclass correlation coefficient of 0.54 (95% Cl 0.31 to 0.70). However, the two methods produced significantly different estimates of resource use with patient self report recalling a mean of 1.3 extra visits (95% Cl 0.4 to 2.2) compared with hospital records. Conclusions: Using questionnaires in this study produced data on a greater number of patients compared with examination of hospital records. However, the two data sources did differ in the quantity of physiotherapy used and this should be taken into account in any analysi

Latent traits of impulsivity and compulsivity: towards dimensional psychiatry

Background: The concepts of impulsivity and compulsivity are commonly used in psychiatry. Little is known about whether different manifest measures of impulsivity and compulsivity (behavior, personality, and cognition) map onto underlying latent traits; and if so, their inter-relationship. Methods: 576 adults were recruited using media advertisements. Psychopathological, personality, and cognitive measures of impulsivity and compulsivity were completed. Confirmatory Factor Analysis was used to identify the optimal model. Results: The data were best explained by a two factor model, corresponding to latent traits of impulsivity and compulsivity respectively, which were positively correlated with each other. This model was statistically superior to the alternative models of their being one underlying factor (“disinhibition”) or two anti-correlated factors. Higher scores on the impulsive and compulsive latent factors were each significantly associated with worse quality of life (both p<0.0001). Conclusions: This study supports the existence of latent functionally impairing dimensional forms of impulsivity and compulsivity, which are positively correlated. Future work should examine the neurobiological and neurochemical underpinnings of these latent traits; and explore whether they can be used as candidate treatment targets. The findings have implications for diagnostic classification systems, suggesting that combining categorical and dimensional approaches may be valuable and clinically relevant
