Human resources for control of tuberculosis and HIV-associated tuberculosis.

The global targets for tuberculosis (TB) control were postponed from 2000 to 2005, but on current evidence a further postponement may be necessary. Of the constraints preventing these targets being met, the primary one appears to be the lack of adequately trained and qualified staff. This paper outlines: 1) the human resources and skills for global TB and human immunodeficiency virus (HIV) TB control, including the human resources for implementing the DOTS strategy, the additional human resources for implementing joint HIV-TB control strategies and what is known about human resource gaps at global level; 2) the attempts to quantify human resource gaps by focusing on a small country in sub-Saharan Africa, Malawi; and 3) the main constraints to human resources and their possible solutions, under six main headings: human resource planning; production of human resources; distribution of the work-force; motivation and staff retention; quality of existing staff; and the effect of HIV/AIDS. We recommend an urgent shift in thinking about the human resource paradigm, and exhort international policy makers and the donor community to make a concerted effort to bridge the current gaps by investing for real change

The neural correlates of childhood maltreatment and the ability to understand mental states of others

$\textbf{Background}$: Emotional abuse and emotional neglect are related to impaired interpersonal functioning. One underlying mechanism could be a developmental delay in mentalizing, the ability to understand other people’s thoughts and emotions. $\textbf{Objective}$: This study investigates the neural correlates of mentalizing and the specific relationship with emotional abuse and neglect whilst taking into account the level of sexual abuse, physical abuse and physical neglect. $\textbf{Method}$: The RMET was performed in an fMRI scanner by 46 adolescents (Age: $\textit{M}$ = 18.70, $\textit{SD}$ = 1.46) who reported a large range of emotional abuse and/or emotional neglect. CM was measured using a self-report questionnaire (CTQ). $\textbf{Results}$: Neither severity of emotional abuse nor neglect related to RMET accuracy or reaction time. The severity of sexual abuse was related to an increased activation of the left IFG during mentalization even when controlled for psychopathology and other important covariates. This increased activation was only found in a group reporting both sexual abuse and emotional maltreatment and not when reporting isolated emotional abuse or neglect or no maltreatment. Functional connectivity analysis showed that activation in the left IFG was associated with increased activation in the right insula and right STG, indicating that the IFG activation occurs in a network relevant for mentalizing. $\textbf{Conclusions}$: Being sexually abused in the context of emotional abuse and neglect is related to an increase in activation of the left IFG, which may indicate a delayed development of mirroring other people’s thoughts and emotions. Even though thoughts and emotions were correctly decoded from faces, the heightened activity of the left IFG could be an underlying mechanism for impaired interpersonal functioning when social situations are more complex or more related to maltreatment experiences.This work was supported by The Netherlands Organisation for Scientific Research (NWO)-E.A.C., VICI-grant [453-14- 001], B.M.E., VIDI-grant [016-085-353], A.L.v.H., Rubicon grant [446-13-006] and by the Royal Society-A.L.v.H., Dorothy Hodgkin Fellowship [DH150176]

A tangled start:The link between childhood maltreatment, psychopathology, and relationships in adulthood

Background: Adults with a history of childhood maltreatment are more likely to experience distrust, feel distant from others, and develop an insecure attachment style which may also affect relationship quality. Furthermore, childhood maltreatment has been linked to several mental health problems; including, depression, anxiety, and alcohol dependance severity, that are also known to relationship quality. Objective: The current study was designed to investigate to what extent childhood maltreatment is associated with adult insecure attachment and intimate relationships and whether this association is mediated by psychopathology. Participants and Method: In a study comprised of 2035 adults aged 18-65, we investigated whether childhood maltreatment was associated with insecure adult attachment styles and the quality of intimate relationships and whether this was mediated by depression, anxiety, and alcohol dependence severity (based on repeated assessments of the Inventory of Depressive Symptomatology-Self Report, Beck Anxiety Index, and Alcohol Use Disorders Identification Test respectively). Results: The path model showed an acceptable fit, RMSEA = 0.05, and suggested full mediation of the association of childhood maltreatment with quality of intimate relationships by depression severity and a) anxious attachment (13 = -4.0 * 10-2; 95% CI = -5.5 * 10-2, -2.7 * 10-2) and b) avoidant attachment (13 = -7.2 * 10-2; 95% CI = -9.6 * 10-2, -4.9 * 10-2). Anxiety and alcohol dependence severity were not significant mediators. Conclusions: Childhood maltreatment is associated with a lower quality of intimate relationships, which is fully mediated by depression severity and insecure attachment styles.Prevention, Population and Disease management (PrePoD)Public Health and primary car

Complete solution of a constrained tropical optimization problem with application to location analysis

We present a multidimensional optimization problem that is formulated and solved in the tropical mathematics setting. The problem consists of minimizing a nonlinear objective function defined on vectors over an idempotent semifield by means of a conjugate transposition operator, subject to constraints in the form of linear vector inequalities. A complete direct solution to the problem under fairly general assumptions is given in a compact vector form suitable for both further analysis and practical implementation. We apply the result to solve a multidimensional minimax single facility location problem with Chebyshev distance and with inequality constraints imposed on the feasible location area.Comment: 20 pages, 3 figure

Understanding Bipolar Disorder Within a Biopsychosocial Emotion Dysregulation Framework

This is the author accepted manuscript. The final version is available on open access from Elsevier via the DOI in this recordBipolar disorder is characterized by extreme mood fluctuations and ongoing affective instability. Mechanisms involved in emotion regulation (ER) seem to be a contributing factor, however the nature and extent of these are not clear yet. The aim of the current review is to contribute to a comprehensive model that covers the full scope of the emotion regulation processes in BD, in order to understand the psychological mechanisms that could contribute to the onset of both manic and depressive states. To this end we review each stage (attentional, behavioural and cognitive processes) of the Process Model of Emotion Regulation in relation to the extant literature on mood or emotion-linked responses in BD. Additionally, potential vulnerability factors (e.g. biological, genetic, personality) for dysfunctional emotion regulation patterns are described. We conclude that on all levels of the emotion regulation model there are seemingly contradictory findings in BD, with evidence for a profile that is characterized by the tendency to upregulate positive affect, as well as a profile that tends to over-use downregulation strategies for both positive and negative affect. These profiles could be characterized by different emotion regulation mechanisms, personality profiles and biological and psychological vulnerability factors. Based on these findings we tentatively identify two emotion regulation profiles in BD (reflecting ‘approach’ and ‘avoidant’ behaviours respectively) and discuss clinical implications and different treatment approaches. To illustrate the latter, we present two clinical cases of both ER profiles and their different treatment approaches

Parents’ experiences of childhood abuse and neglect are differentially associated with behavioral and autonomic responses to their offspring

Although childhood maltreatment has been shown to compromise adaptive parental behavior, little is known what happens in terms of physiological regulation when parents with a history of childhood maltreatment interact with their offspring. Using a sample of 229 parents (131 women), the present study examined whether childhood maltreatment experiences are associated with parents’ behavioral and autonomic responses while resolving conflict with their offspring. Self‐reported experienced child maltreatment was measured using a questionnaire assessing abuse and neglect. Parents (Mage = 52.7 years, rangeage = 26.6–88.4 years) and their offspring (Mage = 24.6 years, rangeage = 7.5–65.6 years) participated in a videotaped parent–offspring conflict interaction task. Parental warmth, negativity, and emotional support were coded. In addition, their pre‐ejection period and respiratory sinus arrhythmia were measured as indicators of underlying sympathetic and parasympathetic nervous system reactivity, respectively. Findings demonstrated that experiences of abuse and neglect were associated with behavioral and physiological responses in different ways. Separating these two types of maltreatment in research and in clinical practice might be important

Contribution to the understanding of tribological properties of graphite intercalation compounds with metal chloride

Intrinsic tribological properties of lamellar compounds are usually attributed to the presence of van der Waals gaps in their structure through which interlayer interactions are weak. The controlled variation of the distances and interactions between graphene layers by intercalation of electrophilic species in graphite is used in order to explore more deeply the friction reduction properties of low-dimensional compounds. Three graphite intercalation compounds with antimony pentachloride, iron trichloride and aluminium trichloride are studied. Their tribological properties are correlated to their structural parameters, and the interlayer interactions are deduced from ab initio bands structure calculations
