BACKGROUND: Wellbeing of healthcare workers is important for the effective functioning of health systems. The aim of this study was to explore the conceptualisations of wellbeing, stress and burnout among healthcare workers in primary healthcare settings in rural Ethiopia in order to inform the development of contextually appropriate interventions. METHODS: A qualitative study was conducted in a rural zone of southern Ethiopia. A total of 52 frontline primary healthcare workers participated in in-depth interviews (n = 18) or Focus Group Discussions (FGDs) (4 groups, total n = 34)...

How stable are human aesthetic preferences, and how does stability change over the lifespan? Here we investigate the stability of aesthetic taste in a cross-sectional study. We employed a simple rank-order preference task using paintings and photographs of faces and landscapes. In each of the four stimulus classes, we find that aesthetic stability generally follows an inverted U-shaped function, with the greatest degree of stability appearing in early to middle adulthood. We propose that one possible interpretation of this result is that it indicates a role for cognitive control (i...

Talia L Retter, Bruno Rossion
The ability to individualize faces is a fundamental human brain function. Following visual adaptation to one individual face, the suppressed neural response to this identity becomes discriminable from an unadapted facial identity at a neural population level. Here, we investigate a simple and objective measure of individual face discrimination with electroencephalographic (EEG) frequency tagging following adaptation. In a first condition, (1) two facial identities are presented in alternation at a rate of six images per second (6 Hz; 3 Hz identity repetition rate) for a 20 s testing sequence, following 10-s adaptation to one of the facial identities; this results in a significant identity discrimination response at 3 Hz in the frequency domain of the EEG over right occipito-temporal channels, replicating our previous findings...

BACKGROUND: Identifying reliable trait markers of familial risk for major depressive disorder (MDD) is a challenge in translational psychiatric research. In individuals with acute MDD, dysfunctional connectivity patterns of prefrontal areas have been shown repeatedly. However, it has been unclear in which neuronal networks functional alterations in individuals at familial risk for MDD might be present and to what extent they resemble findings previously reported in those with acute MDD...

BACKGROUND: Systemic sclerosis (SSc) is an autoimmune disease with multisystem involvement, dominated by a general fibrosis. The early stage of the disease is associated with progressive damage to microcirculation, particularly in the respiratory tract, the gastrointestinal tract and skin. The face assumes a typical appearance characterized by microstomia (reduction of mouth opening) and microcheilia (thinning of the lips). These conditions cause a considerable reduction in performance status of patients...

It is clear that unreinforced repetition (familiarization) influences affective responses to social stimuli, but its effects on the perception of facial emotion are unknown. Reporting the results of two experiments, we show for the first time that repeated exposure enhances the perceived happiness of facial expressions. In Experiment 1, using a paradigm in which subjects' responses were orthogonal to happiness in order to avoid response biases, we found that faces of individuals who had previously been shown were deemed happier than novel faces...

Automatic facial age progression (AFAP) has been an active area of research in recent years. This is due to its numerous applications which include searching for missing. This study presents a new method of AFAP. Here, we use an active appearance model (AAM) to extract facial features from available images. An aging function is then modelled using sparse partial least squares regression (sPLS). Thereafter, the aging function is used to render new faces at different ages. To test the accuracy of our algorithm, extensive evaluation is conducted using a database of 500 face images with known ages...

BACKGROUND: Double eye-lid surgery is one of the most popular performed aesthetic procedures in young Asians. Reliable measurement of patient reported outcomes is crucial for facial aesthetics. The FACE-Q is a new patient-reported outcome tool (PRO) composed of numerous independently functioning scales and checklists designed to measure outcomes. Here we described FACE-Q scales for double eye-lid surgery with minor incision in young Asians. METHODS: 200 patients (400 eyes) aged from 21 to 30 years-old were recruited from 2012 to 2014...

Background Recent genome-wide association studies have identified transient receptor potential M8 ( TRPM8) as a migraine susceptibility gene. TRPM8 is a nonselective cation channel that mediates cool perception. However, its precise role in migraine pathophysiology is elusive. Transient receptor potential V1 (TRPV1) is a nonselective cation channel activated by noxious heat. Both TRPM8 and TRPV1 are expressed in trigeminal ganglion (TG) neurons. Methods We investigated the functional roles of TRPM8 and TRPV1 in a meningeal inflammation-based migraine model by measuring the effects of facial TRPM8 activation on thermal allodynia and assessing receptor coexpression changes in TG neurons...

BACKGROUND: The ability to perform nonsurgical facial rejuvenation procedures is a core competency requirement for plastic surgery residents. However, limited data exist on training models to achieve competency in nonsurgical facial rejuvenation and on outcomes of these procedures performed by residents. The purpose here is to evaluate patient-reported outcomes and safety of nonsurgical facial rejuvenation procedures performed by plastic surgery residents. METHODS: We prospectively enrolled 50 patients undergoing neuromodulator and/or soft-tissue filler injections in a resident cosmetic clinic between April and August 2016...

PURPOSE: Macular telangiectasia Type 2 is a bilateral, progressive, potentially blinding retinal disease characterized by both vascular and neurodegenerative signs. Both the area of the break in the ellipsoid zone seen in "en face" optical coherence tomographic (OCT) images and microperimetric focal retinal sensitivity loss have been proposed as potential measures of progression in macular telangiectasia. The authors aimed to assess the characteristics and interrelationship of these structural and functional disease markers from the data collected in a phase one clinical trial of ciliary neurotrophic factor in macular telangiectasia...

Crouzon syndrome is a rare genetic disorder with autosomal-dominant inheritance that shows a triad of hallmark characteristics: craniosynostosis, exophthalmos, and midface retrusion. General treatment protocol for patients with Crouzon syndrome has already been established, but there is no standard treatment strategy for adult patients with Crouzonoid appearance. The authors present clinical patients of 1-stage orthognathic and face contouring surgery to achieve functional and aesthetic improvement.One-stage surgery was performed in adult patients with Crouzonoid appearance without a history of facial surgery...

Raj Shah, Danielle Witt, Talal Asif, Fahad F Mir
Ipilimumab is a human monoclonal antibody that functions as a cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitor that is used to treat malignant melanoma. Due to ipilimumab's removal of immune regulation, specifically through the inactivation of CTLA-4, it is commonly associated with inflammatory and autoimmune events. Gastrointestinal (GI) related immune-related adverse events such as diarrhea occur in 29% of patients with 7.6% of patients specifically suffering from colitis. We describe a case of colonic perforation with ipilimumab use...

The phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS) is a structurally and functionally complex system that mediates sugar uptake in bacteria. Besides several soluble subunits, the glucose-specific PTS includes the integral membrane protein IICB that couples the transmembrane transport of glucose to its phosphorylation. Here, we used electron crystallography of sugar-embedded tubular crystals of the glucose-specific IIC transport domain from Escherichia coli (ecIIC(glc)) to visualize the structure of the transporter in the presence and absence of its substrate...

Two different measurement techniques were applied to study the attachment of the smooth foot pads of the Madagascar hissing cockroach Gromphadorhina portentosa The attachment of the non-manipulated adhesive organs was compared with that of manipulated ones (depletion or substitution by artificial secretions). From measurements of the friction on a centrifuge, it can be concluded that on nanorough surfaces, the insect appears to benefit from employing emulsions instead of pure oils to avoid excessive friction...

The dopamine transporter (DAT) regulates dopamine (DA) neurotransmission by recapturing DA into the presynaptic terminals, and is a principal target of the psychostimulant cocaine. The sigma-1 receptor (σ1R) is a molecular chaperone, and its ligands have been shown to modulate dopamine neuronal signaling, although their effects on DAT activity are unclear. Here, we report that the prototypical σ1R agonist (+)-pentazocine potentiated the dose response of cocaine self-administration in rats, consistent with effects of the σR agonists PRE-084 and DTG reported previously...

Qingting Tang, Xu Chen, Jia Hu, Ying Liu
Our study explored how priming with a secure base schema affects the processing of emotional facial stimuli in individuals with attachment anxiety. We enrolled 42 undergraduate students between 18 and 27 years of age, and divided them into two groups: attachment anxiety and attachment secure. All participants were primed under two conditions, the secure priming using references to the partner, and neutral priming using neutral references. We performed repeated attachment security priming combined with a dual-task paradigm and functional magnetic resonance imaging...

Early psychosocial deprivation has profound adverse effects on children's brain and behavioural development, including abnormalities in physical growth, intellectual function, social cognition, and emotional development. Nevertheless, the domain of emotional face processing has appeared in previous research to be relatively spared; here, we test for possible sleeper effects emerging in early adolescence. This study employed event-related potentials (ERPs) to examine the neural correlates of facial emotion processing in 12-year-old children who took part in a randomized controlled trial of foster care as an intervention for early institutionalization...

Face alignment acts as an important task in computer vision. Regression-based methods currently dominate the approach to solving this problem, which generally employ a series of mapping functions from the face appearance to iteratively update the face shape hypothesis. One keypoint here is thus how to perform the regression procedure. In this work, we formulate this regression procedure as a sparse coding problem. We learn two relational dictionaries, one for the face appearance and the other one for the face shape, with coupled reconstruction coefficient to capture their underlying relationships...
