Smart windows in which the transmittance can be controlled on demand are a promising solution for the reduction of energy use in buildings. Windows are often the most energy inefficient part of a building, and so controlling the transmittance has the potential to significantly improve heating costs. Whilst numerous approaches exist, many suitable materials are costly to manufacture and process and so new materials could have a significant impact. Here we describe a gel-based device which is both photo-and electrochromic. The gel matrix is formed by the self-assembly of a naphthalene diimide. The radical anion of the naphthalene diimide can be formed photo or electrochemically, and leads to a desirable transition from transparent to black. The speed of response, low potential needed to generate the radical anion, cyclability of the system, temperature stability and low cost mean these devices may be suitable for applications in smart windows.

BackgroundWith the advent of the fifth edition of Diagnostic and Statistical Manual of Mental Disorders, body dysmorphic disorder (BDD) has been subsumed into the obsessive-compulsive disorders and related disorders (OCDRD) category.ObjectiveWe aimed to determine the empirical evidence regarding the potential relationship between BDD and obsessive-compulsive disorder (OCD) based on the prevalence data, etiopathogenic pathways, and clinical characterization of patients with both disorders.MethodA comprehensive search of databases (PubMed and PsycINFO) was performed. Published manuscripts between 1985 and May 2015 were identified. Overall, 53 studies fulfilled inclusion criteria.ResultsLifetime comorbidity rates of BDD–OCD are almost three times higher in samples with a primary diagnosis of BDD than those with primary OCD (27.5% vs 10.4%). However, other mental disorders, such as social phobia or major mood depression, are more likely among both types of psychiatric samples. Empirical evidence regarding the etiopathogenic pathways for BDD–OCD comorbidity is still inconclusive, whether concerning common shared features or one disorder as a risk factor for the other. Specifically, current findings concerning third variables show more divergences than similarities when comparing both disorders. Preliminary data on the clinical characterization of the patients with BDD and OCD indicate that the deleterious clinical impact of BDD in OCD patients is greater than vice versa.ConclusionDespite the recent inclusion of BDD within the OCDRD, data from comparative studies between BDD and OCD need further evidence for supporting this nosological approach. To better define this issue, comparative studies between BDD, OCD, and social phobia should be carried out.

These findings support a specific relationship between childhood emotional abuse and the occurrence of BPD, which may be accounted for by preoccupied-anxious adult attachment. Copyright © 2016 John Wiley & Sons, Ltd.

In Latin American countries, obesity prevalence has increased significantly as a result of rapid urbanization and an improvement in socioeconomic conditions. We report the prevalence of overweight and/or obesity and prevention efforts in five countries: Mexico, Colombia, Brazil, Peru, and Chile. In children, the highest and lowest rates of obesity are found in Chile (23 % in 6-year-olds) and Peru (1.8 % in those <5 years), respectively. In adults, Mexico and Chile present similar high rates of obesity (around 35 %), whereas in Brazil and Colombia, the rates are around 20 % and 16.5 %, respectively. In general, the highest prevalence occurs in low-income women. Every country has developed initiatives to target obesity, from the government to the private sector and academia, mainly at the health sector and school settings. Food labeling is being addressed, but has not been implemented yet. Two interventions are described, a community-based in Mexico and a school-based in Chile. Because the increase in chronic diseases, especially diabetes, has paralleled that of obesity, effective prevention efforts are urgently needed.

In the small group of overweight and obese patients in this study, 52.1% used CTPs. In obese women, those with a higher educational level and/or who were single were more likely to use CTPs. Patients were also more likely to use CTPs if they had a negative view of their current nutritional therapy.

Sexual masochism disorder is considered the most prevalent paraphilia among women. However, little is known about the etiology and clinical correlates involved in this disorder. We aimed at addressing this issue through a potentially high-risk clinical cohort. This case-control study consisted of 60 women who met DSM-IV criteria for borderline personality disorder (BPD) and 60 women with other personality disorders. For both groups, sexual masochism disorder comorbidity was assessed through the Structured Clinical Interview, Sexual Disorders Module. Several etiological, psychosexual, and personality features were measured. Sexual masochism disorder was 10 times higher in BPD women than in women with other personality disorders (10 vs. 0 %). Among BPD women, those with sexual masochism disorder reported more child sexual abuse, more hostile/dismissing attachments, higher sensation seeking, and more frequently exploratory/impersonal sexual fantasies than BPD without sexual masochism. Correlation analysis confirmed a significant positive relationship between disinhibition and sexual masochism severity for BPD women. Our findings point out that BPD women may represent a high-risk cohort, especially those with higher disinhibition and detached attachment. Childhood sexual abuse may also play a predispositional role on this comorbidity. Further research may help to elucidate the intriguing relationship between both disorders.
