Epigenetic modification of OXT and human sociability

Significance Elucidating the genetic and biological substrates of social behavior serves to advance the way basic human nature is understood and improves the way genetic and biological markers can be used to prevent, diagnose, and treat people with impairments in social cognition and behavior. This study shows that epigenetic modification of the structural gene for oxytocin (OXT) is an important factor associated with individual differences in social processing, including self-report, behavior, and brain function and structure in humans. Across many mammalian species there exist genetic and biological systems that facilitate the tendency to be social. Oxytocin is a neuropeptide involved in social-approach behaviors in humans and others mammals. Although there exists a large, mounting body of evidence showing that oxytocin signaling genes are associated with human sociability, very little is currently known regarding the way the structural gene for oxytocin (OXT) confers individual differences in human sociability. In this study, we undertook a comprehensive approach to investigate the association between epigenetic modification of OXT via DNA methylation, and overt measures of social processing, including self-report, behavior, and brain function and structure. Genetic data were collected via saliva samples and analyzed to target and quantify DNA methylation across the promoter region of OXT. We observed a consistent pattern of results across sociability measures. People that exhibit lower OXT DNA methylation (presumably linked to higher OXT expression) display more secure attachment styles, improved ability to recognize emotional facial expressions, greater superior temporal sulcus activity during two social-cognitive functional MRI tasks, and larger fusiform gyrus gray matter volume than people that exhibit higher OXT DNA methylation. These findings provide empirical evidence that epigenetic modification of OXT is linked to several overt measures of sociability in humans and serve to advance progress in translational social neuroscience research toward a better understanding of the evolutionary and genetic basis of normal and abnormal human sociability.
Primary cutaneous peripheral T‐cell lymphoma, unspecified with an indolent clinical course: a distinct peripheral T‐cell lymphoma?

Primary cutaneous peripheral T‐cell lymphomas (PTL), unspecified, are rare lymphomas, with a poor prognosis. They grow and disseminate rapidly, leading to widespread disease. We report a case of PTL, unspecified occurring on the nose. Despite its aggressive histology, this tumour behaved indolently. It is remarkably similar, clinically and histologically, to four recently described cases that occurred on the ear.
Sphingomyelin is sorted at the trans Golgi network into a distinct class of secretory vesicle

Significance The biochemical reactions that drive cellular life are housed in distinct membrane enclosed compartments known as organelles. Whereas proteins targeting to different organelles are well developed, little is known regarding how lipids are sorted to different organelles. We engineered a protein from a marine organism into a fluorescent “biosensor” of sphingomyelin (SM), a sphingolipid that is produced in the Golgi apparatus but is a major component of the plasma membrane. By monitoring SM dynamics in live cells, we discovered that SM is transported from its site of synthesis in the Golgi to the plasma membrane in a distinct type of secretory transport carrier. Our findings show that vesicle-based trafficking pathways are specialized to transport distinct types of lipids, in addition to proteins. One of the principal functions of the trans Golgi network (TGN) is the sorting of proteins into distinct vesicular transport carriers that mediate secretion and interorganelle trafficking. Are lipids also sorted into distinct TGN-derived carriers? The Golgi is the principal site of the synthesis of sphingomyelin (SM), an abundant sphingolipid that is transported. To address the specificity of SM transport to the plasma membrane, we engineered a natural SM-binding pore-forming toxin, equinatoxin II (Eqt), into a nontoxic reporter termed Eqt-SM and used it to monitor intracellular trafficking of SM. Using quantitative live cell imaging, we found that Eqt-SM is enriched in a subset of TGN-derived secretory vesicles that are also enriched in a glycophosphatidylinositol-anchored protein. In contrast, an integral membrane secretory protein (CD8α) is not enriched in these carriers. Our results demonstrate the sorting of native SM at the TGN and its transport to the plasma membrane by specific carriers.
The Language of Cigar Use: Focus Group Findings on Cigar Product Terminology.

INTRODUCTION The consumption of cigar products has increased since 2000. The multiple product types within this category, combined with the varied language with which consumers refer to them, present challenges for accurately assessing the prevalence of cigar product use. Surveillance is also complicated by the fact that these products can be used to smoke marijuana, as "blunts"-cigars in which the tobacco is removed and replaced with marijuana. Few studies exist regarding the language and terminology used to describe these products. METHODS Sixteen focus groups were conducted in five cities in the United States between March and May of 2014. Participants (N = 123) included adults who had used cigars, cigarillos, or little cigars in the past 30 days. A semi-structured moderator guide was used to gather data on the terms used to identify cigar product subtypes and the language used to describe the products and their use. RESULTS Participants used a variety of terms for each product subtype. Brand names were often used, as well as slang terms, including terms describing cigars modified for marijuana use. Some subtypes were less likely than others to be considered "cigars. " Participants had mixed opinions about whether users of cigar products are "smokers. " CONCLUSIONS Users of cigar products may classify or label products differently from researchers and policy makers, and many refer to their product by brand name or a slang term. These findings have implications for future research, instrument design, and public health messaging about cigar products. IMPLICATIONS This study adds to the body of evidence highlighting the challenges for measurement and surveillance of non-cigarette tobacco products, including cigars. Findings illustrate the myriad terms used by consumers to describe their use of cigar product subtypes, as well as the complexity of distinguishing between use of cigar products as intended, versus as a vehicle for smoking marijuana. Future research aimed to enhance specificity of cigar use measures will enable policy-makers and public health practitioners to more fully characterize prevalence and patterns of use by cigar subtype.
Exploring Issues of Comorbid Conditions in People Who Smoke.

UNLABELLED Smoking affects comorbid disease outcomes, and patients with comorbid conditions may have unique characteristics that are important to consider when treating tobacco use. However, addressing tobacco in patients being treated for comorbid conditions is not a consistent practice. Recognizing the need for a "call-to-action" to address tobacco use in people with comorbid conditions, the Tobacco Treatment Network within the Society for Research on Nicotine and Tobacco (SRNT) convened a Comorbidities Workgroup to explore the relationship between smoking and comorbid disease to identify common themes including: the harms associated with continued tobacco use, the frequency of comorbid disease and tobacco use, the potential effect of comorbid disease on the ability to quit tobacco use, the association between tobacco use and suboptimal disease-specific treatment response, and evidence regarding potential approaches to improve addressing tobacco use in patients with comorbid disease. Five candidate conditions (psychiatric, cancer, cardiovascular, pulmonary, and human immunodeficiency virus infected patients) were explored. Across comorbid conditions, smoking adversely affects treatment efficacy and promotes other adverse health conditions. People with comorbid conditions who smoke are motivated to quit and respond to evidence-based smoking cessation treatments. However, tobacco cessation is not regularly incorporated into the clinical care of many individuals with comorbidities. Optimal strategies for addressing tobacco use within each comorbid disease are also not well defined. Further work is needed to disseminate evidence-based care into clinical practice for smokers with comorbid disease and addiction research should consider comorbid conditions as an important construct to explore. IMPLICATIONS This article explores how physical and psychiatric conditions may interact in the treatment of tobacco dependence, and discusses the need for smoking cessation as a critical component of comorbid condition management. Five common comorbid domains-psychiatric, cancer, pulmonary, cardiovascular, and human immunodeficiency virus (HIV)-are highlighted to illustrate how these different conditions might interact with smoking with respect to prevalence and harm, motivation to quit, and cessation treatment utilization and success.
Electronic Cigarettes for Smoking Cessation: A Systematic Review.

BACKGROUND AND AIMS Electronic cigarettes (e-cigarettes) have been steadily increasing in popularity among smokers, most of whom report using them to quit smoking. This study systematically reviews the current literature on the effectiveness of e-cigarettes as cessation aids. METHODS We searched PubMed, MEDLINE, PsycINFO, CINAHL, ERIC, ROVER, Scopus, ISI Web of Science, Cochrane Library, the Ontario Tobacco Research Unit (OTRU) library catalogue, and various gray literature sources. We included all English-language, empirical quantitative and qualitative papers that investigated primary cessation outcomes (smoking abstinence or reduction) or secondary outcomes (abstinence-related withdrawal symptoms and craving reductions) and were published on or before February 1, 2016. RESULTS Literature searches identified 2855 references. After removing duplicates and screening for eligibility, 62 relevant references were reviewed and appraised. In accordance with the GRADE system, the quality of the evidence in support of e-cigarettes' effectiveness in helping smokers quit was assessed as very low to low, and the evidence on smoking reduction was assessed as very low to moderate. The majority of included studies found that e-cigarettes, especially second-generation types, could alleviate smoking withdrawal symptoms and cravings in laboratory settings. CONCLUSIONS While the majority of studies demonstrate a positive relationship between e-cigarette use and smoking cessation, the evidence remains inconclusive due to the low quality of the research published to date. Well-designed randomized controlled trials and longitudinal, population studies are needed to further elucidate the role of e-cigarettes in smoking cessation. IMPLICATIONS This is the most comprehensive systematic evidence review to examine the relationship between e-cigarette use and smoking cessation among smokers. This review offers balanced and rigorous qualitative and quantitative analyses of published evidence on the effectiveness of e-cigarette use for smoking abstinence and reduction as well as important outcomes such as withdrawal symptoms and craving to smoke. While inconclusive due to low quality, overall the existing literature suggests e-cigarettes may be helpful for some smokers for quitting or reducing smoking. However, more carefully designed and scientifically sound studies are urgently needed to establish unequivocally the long-term cessation effects of e-cigarettes and to better understand of how and when e-cigarettes may be helpful.
Synergistic and Non-synergistic Associations for Cigarette Smoking and Non-tobacco Risk Factors for Cardiovascular Disease Incidence in the Atherosclerosis Risk In Communities (ARIC) Study

Introduction Cigarette smoking, various metabolic and lipid-related factors and hypertension are well-recognized cardiovascular disease (CVD) risk factors. Since smoking affects many of these factors, use of a single imprecise smoking metric, for example, ever or never smoked, may allow residual confounding and explain inconsistencies in current assessments of interactions. Methods Using a comprehensive model in pack-years and cigarettes/day for the complex smoking-related relative risk (RR) of CVD to reduce residual confounding, we evaluated interactions with non-tobacco risk factors, including additive (non-synergistic) and multiplicative (synergistic) forms. Data were from the prospective Atherosclerosis Risk in Communities (ARIC) Study from four areas of the United States recruited in 1987-1989 with follow-up through 2008. Analyses included 14 127 participants, 207 693 person-years and 2857 CVD events. Results Analyses revealed distinct interactions with smoking: including statistical consistency with additive (body mass index [BMI], waist to hip ratio [WHR], diabetes mellitus [DM], glucose, insulin, high density lipoproteins [HDL] and HDL(2)); and multiplicative (hypertension, total cholesterol [TC], low density lipoproteins [LDLs], apolipoprotein B [apoB], TC to HDL ratio and HDL(3)) associations, as well as indeterminate (apolipoprotein A-I [apoA-I] and triglycerides) associations. Conclusions The forms of the interactions were revealing but require confirmation. Improved understanding of joint associations may help clarify the public health burden of smoking for CVD, links between etiologic factors and biological mechanisms, and the consequences of joint exposures, whereby synergistic associations highlight joint effects and non-synergistic associations suggest distinct contributions. Implications Joint associations for cigarette smoking and non-tobacco risk factors were distinct, revealing synergistic/multiplicative (hypertension, TC, LDL, apoB, TC/HDL, HDL(3)), non-synergistic/additive (BMI, WHR, DM, glucose, insulin, HDL, HDL(2)) and indeterminate (apoA-I and TRIG) associations. If confirmed, these results may help better define the public health burden of smoking on CVD risk and identify links between etiologic factors and biologic mechanisms, where synergistic associations highlight joint impacts and non-synergistic associations suggest distinct contributions from each factor.
Flexible and Responsive Chiral Nematic Cellulose Nanocrystal/Poly(ethylene glycol) Composite Films with Uniform and Tunable Structural Color

The fabrication of responsive photonic structures from cellulose nanocrystals (CNCs) that can operate in the entire visible spectrum is challenging due to the requirements of precise periodic modulation of the pitch size of the self‐assembled multilayer structures at the length scale within the wavelength of the visible light. The surface charge density of CNCs is an important factor in controlling the pitch size of the chiral nematic structure of the dried solid CNC films. The assembly of poly(ethylene glycol) (PEG) together with CNCs into smaller chiral nematic domains results in solid films with uniform helical structure upon slow drying. Large, flexible, and flat photonic composite films with uniform structure colors from blue to red are prepared by changing the composition of CNCs and PEG. The CNC/PEG(80/20) composite film demonstrates a reversible and smooth structural color change between green and transparent in response to an increase and decrease of relative humidity between 50% and 100% owing to the reversible swelling and dehydration of the chiral nematic structure. The composite also shows excellent mechanical and thermal properties, complementing the multifunctional property profile.
Decline in the negative association between low birth weight and cognitive ability

Significance Many studies have shown that children with a low birth weight (less than 2.5 kg) have worse cognitive ability than children with a normal birth weight. No existing study has analyzed whether, given the advances in neonatology and obstetric practice that have occurred over the past 50 years in developed contexts, the association between low birth weight and cognitive ability has changed over time. Using data from the 1958 National Child Development Study, the 1970 British Cohort Study, and the 2000–2002 Millennium Cohort Study, we show that the association between low birth weight and decreased cognitive ability has been more than halved between the 1958 and 1970 birth cohorts and the cohort born around the year 2001. Low birth weight predicts compromised cognitive ability. We used data from the 1958 National Child Development Study (NCDS), the 1970 British Cohort Study (BCS), and the 2000–2002 Millennium Cohort Study (MCS) to analyze how this association has changed over time. Birth weight was divided into two categories, <2,500 g (low) and 2,500–4,500 g (normal) and verbal cognitive ability was measured at the age of 10 or 11 y. A range of maternal and family characteristics collected at or soon after the time of birth were considered. Linear regression was used to analyze the association between birth weight and cognitive ability in a baseline model and in a model that adjusted for family characteristics. The standardized difference (SD) in cognitive scores between low-birth-weight and normal-birth-weight children was large in the NCDS [−0.37 SD, 95% confidence interval (CI): −0.46, −0.27] and in the BCS (−0.34, 95% CI: −0.43, −0.25) cohorts, and it was more than halved for children born in the MCS cohort (−0.14, 95% CI: −0.22, −0.06). The adjustment for family characteristics did not explain the cross-cohort differences. The results show that the association between low birth weight and decreased cognitive ability has declined between the 1950s and 1970s birth cohorts and the 2000--2002 birth cohort, despite a higher proportion of the low-birth-weight babies having a very low birth weight (<1,500 g) in the more recent birth cohort. Advancements in obstetric and neonatal care may have attenuated the negative consequences associated with being born small.

Opportunities Missed: A Cross-Sectional Survey of the Provision of Smoking Cessation Care to Pregnant Women by Australian General Practitioners and Obstetricians

Introduction Similar to other high-income countries, smoking rates in pregnancy can be high in specific vulnerable groups in Australia. Several clinical guidelines exist, including the 5A's (Ask, Advice, Assess, Assist, and Arrange), ABCD (Ask, Brief advice, Cessation, and Discuss), and AAR (Ask, Advice, and Refer). There is lack of data on provision of smoking cessation care (SCC) of Australian General Practitioners (GPs) and Obstetricians. Methods A cross-sectional survey explored the provision of SCC, barriers and enablers using the Theoretical Domains Framework, and the associations between them. Two samples were invited: (1) GPs and Obstetricians from a college database (n = 5571); (2) GPs from a special interest group for Indigenous health (n = 500). Dimension reduction for the Theoretical Domains Framework was achieved with factor analysis. Logistic regression was carried out for performing all the 5A's and the AAR. Results Performing all of the 5A's, ABCD, and AAR "often and always" was reported by 19.9%, 15.6%, and 49.2% respectively. "Internal influences" (such as confidence in counselling) were associated with higher performance of the 5A's (Adjusted OR 2.69 (95% CI 1.5, 4.8), p < . 001), whereas "External influences" (such as workplace routine) were associated with higher performance of AAR (Adjusted OR 1.7 (95% CI 1, 2.8), p = . 035). Conclusions Performance in providing SCC to pregnant women is low among Australian GPs and Obstetricians. Training clinicians should focus on improving internal influences such as confidence and optimism. The AAR may be easier to implement, and interventions at the service level should focus on ensuring easy, effective, and acceptable referral mechanisms are in place. Implications Improving provision of the 5A's approach should focus on the individual level, including better training for GPs and Obstetricians, designed to improve specific "internal" barriers such as confidence in counselling and optimism. The AAR may be easier to implement in view of the higher overall performance of this approach. Interventions on a more systemic level need to ensure easy, effective, and acceptable referral mechanisms are in place. More research is needed specifically on the acceptability of the Quitline for pregnant women, both Indigenous and non-Indigenous.
