Male Body Image Portrayals on Instagram

Men are faced with trends that give rise to the desire for a muscular and lean body; this may result in body dissatisfaction. Body dissatisfaction is associated with a plethora of health consequences. Social media has been named as one contributing factor for male body dissatisfaction. Up till now, women have been the focus of body image-related social media studies. Therefore, we conducted a quantitative content analysis of 1,000 relevant Instagram posts that were posted by men (and/or depicted men) to understand how the male body is depicted on Instagram and how user respond to those images. The majority of sampled posts showed high levels of muscularity and leanness. In addition, posts depicting men adhering to this specific body type received significantly more responses (likes and comments). Norms and outcomes related to health (i.e., training to be healthy) were more commonly shown than appearance-related constructs (i.e., training to become attractive), and promotion of physical activity was more common than dietary behavior. However, findings are potential harmful to men's body image, even if one considers that health-related messaging and physical active promotion was prominent. It remains debatable if men need to view very lean and very muscular to encourage health-related behaviors.
Assessment of the Status of Patients with Parkinson’s Disease Using Neural Networks and Mobile Phone Sensors

Parkinson’s disease (PD) is one of the most common chronic neurological diseases and one of the significant causes of disability for middle-aged and elderly people. Monitoring the patient’s condition and its compliance is the key to the success of the correction of the main clinical manifestations of PD, including the almost inevitable modification of the clinical picture of the disease against the background of prolonged dopaminergic therapy. In this article, we proposed an approach to assessing the condition of patients with PD using deep recurrent neural networks, trained on data measured using mobile phones. The data was received in two modes: background (data from the phone’s sensors) and interactive (data directly entered by the user). For the classification of the patient’s condition, we built various models of the neural network. Testing of these models showed that the most efficient was a recurrent network with two layers. The results of the experiment show that with a sufficient amount of the training sample, it is possible to build a neural network that determines the condition of the patient according to the data from the mobile phone sensors with a high probability.
Seasonal Variation in Activity Budget of Assamese Macaques in Limestone Forest of Southwest Guangxi, China

The activity budget is important for understanding behavioural variability and adaptation in primates. Assamese macaques (Macaca assamensis) found in the limestone forest of Guangxi Nonggang National Nature Reserve, Southwest China, primarily feed on young leaves of Bonia saxatilis (a shrubby, karst-endemic bamboo). To understand how a specific bamboo leaf-based diet and ecological factors affect activity budget, one group of Assamese macaques was studied using instantaneous scan sampling for 1 year. The macaques spent most of their time feeding (32.7 ± 5.4%), followed by resting (28.6 ± 6.3%), moving (28.6 ± 5.3%), grooming (8.0 ± 3.0%), playing (1.7 ± 1.6%) and other activities (0.4 ± 0.2%). Their activity budget was similar to that of typical frugivorous primates and bamboo-dominated primates, which spent more time on active behaviours (feeding and moving, 61.3 ± 6.0%) than on inactive behaviours (resting and grooming, 36.6 ± 6.4%). The macaques spent significantly more time resting during the fruit-lean season and more time moving during the fruit-rich season. Their activity budget was significantly affected by diet. Resting time increased with decreased fruit consumption, whereas moving time decreased with the increasing mature leaf consumption. Playing time decreased when the macaques consumed more young bamboo leaves. The activity budget was also influenced by food availability and climatic factors. Resting time increased with decreasing temperature, whereas moving time increased with increasing day length and young leaf availability. Grooming time increased with decreasing day length and increasing temperature, and playing time increased with increasing day length. Our findings provide evidence of the importance of diet, food availability, temperature and day length in coping with seasonal variation in ecological factors, highlighting the need to increase knowledge of the behavioural ecology of the Assamese macaques living in the unique limestone forest and to understand the influence of a bamboo-dominated diet and ecological factors on their survival.
Identifying and responding to fatigue and apathy in Parkinson’s disease: a review of current practice

ABSTRACT Introduction: Fatigue and apathy are two key non-motor symptoms in Parkinson’s disease (PD), with documented negative impact on Quality of life (QoL) and a frequent burden for caregivers. Areas covered: In this review, the authors comment on the latest pathophysiology, clinical phenomenology, the most frequently used scales for fatigue and apathy in PD with a focus on available therapeutic strategies. Expert opinion:The identification of fatigue and apathy in PD is mainly hampered by the lack of a clear consensus on these subjective symptoms. The pathophysiological processes remain unclear, and the large variation in prevalence is likely due to the heterogeneous PD populations and the lack of an enriched cohort of people with fatigue and/or apathy as main symptoms. Treatment strategies, and especially level 1 evidence for specific treatments for fatigue and apathy in PD, remain scarce. The best evidence to date is doxepin, rasagiline and levodopa infusion therapy (for fatigue), and rivastigmine (for apathy). Further efforts should be made to properly identify these two major symptoms in PD, to correctly detect those who may benefit most from tailored personalized interventions.
Micro-Pattern of Graphene Oxide Films Using Metal Bonding

Recently, graphene has been explored in several research areas according to its outstanding combination of mechanical and electrical features. The ability to fabricate micro-patterns of graphene facilitates its integration in emerging technologies such as flexible electronics. This work reports a novel micro-pattern approach of graphene oxide (GO) film on a polymer substrate using metal bonding. It is shown that adding ethanol to the GO aqueous dispersion enhances substantially the uniformity of GO thin film deposition, which is a great asset for mass production. On the other hand, the presence of ethanol in the GO solution hinders the fabrication of patterned GO films using the standard lift-off process. To overcome this, the fabrication process provided in this work takes advantage of the chemical adhesion between the GO or reduced GO (rGO) and metal films. It is proved that the adhesion between the metal layer and GO or rGO is stronger than the adhesion between the latter and the polymer substrate (i.e., cyclic olefin copolymer used in this work). This causes the removal of the GO layer underneath the metal film during the lift-off process, leaving behind the desired GO or rGO micro-patterns. The feasibility and suitability of the proposed pattern technique is confirmed by fabricating the patterned electrodes inside a microfluidic device to manipulate living cells using dielectrophoresis. This work adds great value to micro-pattern GO and rGO thin films and has immense potential to achieve high yield production in emerging applications.
Functionalized Cellulose for the Controlled Synthesis of Novel Carbon–Ti Nanocomposites: Physicochemical and Photocatalytic Properties

Carbon–Ti nanocomposites were prepared by a controlled two-step method using microcrystalline cellulose as a raw material. The synthesis procedure involves the solubilization of cellulose by an acid treatment (H3PO4 or HNO3) and the impregnation with the Ti precursor followed of a carbonization step at 500 or 800 °C. The type of acid treatment leads to a different functionalization of cellulose with phosphorus- or oxygen-containing surface groups, which are able to control the load, dispersion and crystalline phase of Ti during the composite preparation. Thus, phosphorus functionalities lead to amorphous carbon–Ti composites at 500 °C, while TiP2O7 crystals are formed when prepared at 800 °C. On the contrary, oxygenated groups induce the formation of TiO2 rutile at an unusually low temperature (500 °C), while an increase of carbonization temperature promotes a progressive crystal growth. The removal of Orange G (OG) azo dye in aqueous solution, as target pollutant, was used to determine the adsorptive and photocatalytic efficiencies, with all composites being more active than the benchmark TiO2 material (Degussa P25). Carbon–Ti nanocomposites with a developed micro-mesoporosity, reduced band gap and TiO2 rutile phase were the most active in the photodegradation of OG under ultraviolet irradiation.
Diacylglycerol kinase ζ promotes actin cytoskeleton remodeling and mechanical forces at the B cell immune synapse

Optimal B cell responses depend on balanced signaling between DAG and phosphatidic acid, which is regulated by diacylglycerol kinase ζ. Balancing B cell signals Diacylglycerol kinases (DGKs) catalyze the conversion of the lipid signaling molecule DAG into phosphatidic acid (PA), both of which have distinct effects. Merino-Cortés et al. found that the DGKζ isoform was critical in promoting signaling required for the optimal function of B cells. Compared with wild-type B cells, DGKζ-deficient B cells exhibited decreased mechanical forces at the plasma membrane, impairing the ability of these cells to form stable contacts with antigen-presenting cells, extract antigen, and present it to T cells. As a result, mice with DGKζ-deficient B cells showed diminished antibody responses in germinal centers. These data suggest that DGKζ regulates the balance in signaling between DAG and PA that is required for optimal B cell function. Diacylglycerol kinases (DGKs) limit antigen receptor signaling in immune cells by consuming the second messenger diacylglycerol (DAG) to generate phosphatidic acid (PA). Here, we showed that DGKζ promotes lymphocyte function–associated antigen 1 (LFA-1)–mediated adhesion and F-actin generation at the immune synapse of B cells with antigen-presenting cells (APCs), mostly in a PA-dependent manner. Measurement of single-cell mechanical force generation indicated that DGKζ-deficient B cells exerted lower forces at the immune synapse than did wild-type B cells. Nonmuscle myosin activation and translocation of the microtubule-organizing center (MTOC) to the immune synapse were also impaired in DGKζ-deficient B cells. These functional defects correlated with the decreased ability of B cells to present antigen and activate T cells in vitro. The in vivo germinal center response of DGKζ-deficient B cells was also reduced compared with that of wild-type B cells, indicating that loss of DGKζ in B cells impaired T cell help. Together, our data suggest that DGKζ shapes B cell responses by regulating actin remodeling, force generation, and antigen uptake–related events at the immune synapse. Hence, an appropriate balance in the amounts of DAG and PA is required for optimal B cell function.
Antimicrobial Materials with Lime Oil and a Poly(3-hydroxyalkanoate) Produced via Valorisation of Sugar Cane Molasses

A medium chain-length polyhydroxyalkanoate (PHA) was produced by Pseudomonas mendocina CH50 using a cheap carbon substrate, sugarcane molasses. A PHA yield of 14.2% dry cell weight was achieved. Chemical analysis confirmed that the polymer produced was a medium chain-length PHA, a copolymer of 3-hydroxyoctanoate and 3-hydroxydecanoate, P(3HO-co-3HD). Lime oil, an essential oil with known antimicrobial activity, was used as an additive to P(3HO-co-3HD) to confer antibacterial properties to this biodegradable polymer. The incorporation of lime oil induced a slight decrease in crystallinity of P(3HO-co-3HD) films. The antibacterial properties of lime oil were investigated using ISO 20776 against Staphylococcus aureus 6538P and Escherichia coli 8739, showing a higher activity against the Gram-positive bacteria. The higher activity of the oil against S. aureus 6538P defined the higher efficiency of loaded polymer films against this strain. The effect of storage on the antimicrobial properties of the loaded films was investigated. After one-year storage, the content of lime oil in the films decreased, causing a reduction of the antimicrobial activity of the materials produced. However, the films still possessed antibacterial activity against S. aureus 6538P.
Nationwide Analysis of Changes in Medical Utilization Before and After a New Panic Disorder Diagnosis

Supplemental digital content is available in the text. ABSTRACT Objective Panic disorder (PD) is associated with somatization and high medical utilization in primary care settings. Treatment of PD could reduce the frequency of panic attacks and visits to emergency departments, but the associated change in medical utilization is unknown. This study investigated the change in medical utilization before and after a PD diagnosis. Method This study identified 8722 patients with PD enrolled in the National Health Insurance Research Database in Taiwan between January 1, 2000, and December 31, 2012. We used a case-crossover study design to compare medical utilizations with a 1-year time window before and after new PD diagnoses, including medical examinations, specialty visits, and medication used. A conditional logistic regression model was used to estimate changes in comorbidity before and after new PD diagnoses. Results The utilization of examinations—including electrocardiography, radiography, and sonography—decreased within 1 year after PD diagnosis compared with 1 year before PD diagnosis. Outpatient and emergency department visits to nonpsychiatric departments decreased (risk ratio [RR] = 0.989 [95% confidence interval {CI} = 0.985–0.993] and RR = 0.924 [95% CI = 0.894–0.956], respectively), whereas outpatient visits to psychiatric departments increased (RR = 1.193, 95% CI = 1.171–1.215). PD diagnosis is associated with increased use of antidepressants (RR = 12.65) and benzodiazepines (RR = 11.63), an increased ratio of comorbid depressive disorder (RR = 3.06) and bipolar disorder (RR = 1.77), and a decreased ratio of nonpanic anxiety disorder (RR = 0.69). Conclusions New PD diagnoses are associated with decreased laboratory examination and nonpsychiatric service utilization, along with increased psychiatric service utilization. We suggest that PD should be detected earlier for mitigating potentially unnecessary use of nonpsychiatric examinations and services.
Aortic Stiffening Is an Extraintestinal Manifestation of Inflammatory Bowel Disease: Review of the Literature and Expert Panel Statement

Current guidelines state that systemic inflammation, together with endothelial dysfunction, calcification, and hypercoagulability, predispose to premature atherosclerosis in patients with inflammatory bowel disease (IBD). We assessed whether IBD can affect aortic stiffness, a well-recognized vascular biomarker and an independent risk factor for cardiovascular (CV) disease (CVD) in several populations. Recent studies reported that aortic stiffness is increased in adults with IBD compared with matched controls. This association is dependent on inflammatory burden and disease duration, and is reduced by antitumor necrosis factor therapy. Considered together, current findings suggest that increased aortic stiffness is an extraintestinal manifestation of IBD. This is clinically relevant since measuring aortic stiffness in patients with IBD could improve risk assessment, especially in those without established CVD. Moreover, effective control of inflammation could lower CV risk in patients with IBD by reducing aortic stiffness. Further longitudinal studies are needed to better clarify (i) the relationship between disease duration and irreversible changes of the arterial wall, (ii) the clinical characteristics of patients with IBD that have an increased arterial stiffness at least in part reversible, and (iii) whether arterial stiffness is useful to evaluate the efficacy of immunosuppressive therapy.
Transcriptional Profiling of the Probiotic Escherichia coli Nissle 1917 Strain under Simulated Microgravity

Long-term space missions affect the gut microbiome of astronauts, especially the viability of some pathogens. Probiotics may be an effective solution for the management of gut microbiomes, but there is a lack of studies regarding the physiology of probiotics in microgravity. Here, we investigated the effects of microgravity on the probiotic Escherichia coli Nissle 1917 (EcN) by comparing transcriptomic data during exponential and stationary growth phases under simulated microgravity and normal gravity. Microgravity conditions affected several physiological features of EcN, including its growth profile, biofilm formation, stress responses, metal ion transport/utilization, and response to carbon starvation. We found that some changes, such as decreased adhesion ability and acid resistance, may be disadvantageous to EcN relative to gut pathogens under microgravity, indicating the need to develop probiotics optimized for space flight.
Characterization of Platinum-Based Thin Films Deposited by Thermionic Vacuum Arc (TVA) Method

The current work aimed to characterize the morphology, chemical, and mechanical properties of Pt and PtTi thin films deposited via thermionic vacuum arc (TVA) method on glass and silicon substrates. The deposited thin films were characterized by means of a scanning electron microscope technique (SEM). The quantitative elemental microanalysis was done using energy-dispersive X-ray spectroscopy (EDS). The tribological properties were studied by a ball-on-disc tribometer, and the mechanical properties were measured using nanoindentation tests. The roughness, as well as the micro and nanoscale features, were characterized using atomic force microscopy (AFM) and transmission electron microscopy (TEM). The wettability of the deposited Pt and PtTi thin films was investigated by the surface free energy evaluation (SFE) method. The purpose of our study was to prove the potential applications of Pt-based thin films in fields, such as nanoelectronics, fuel cells, medicine, and materials science.
Association Between Visit-to-Visit Blood Pressure Variability in Early Adulthood and Myocardial Structure and Function in Later Life.

Importance Long-term blood pressure (BP) variability has emerged as a reproducible measure that is associated with heart failure independent of systemic BP. Visit-to-visit BP variability may be associated with the risk of heart failure early in the life course and thus may be reflected in subclinical alterations in cardiac structure and function. Objective To evaluate the association between visit-to-visit BP variability in early adulthood and myocardial structure and function in middle age. Design, Setting, and Participants This cohort study used data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, a community-based cohort study of 5115 participants aged 18 to 30 years at baseline (year 0; March 25, 1985, to June 7, 1986) and followed up over a 30-year interval. A total of 2400 CARDIA study participants underwent evaluation at 4 field sites (Birmingham, Alabama; Oakland, California; Chicago, Illinois; and Minneapolis, Minnesota). Blood pressure was measured at 8 visits over a 25-year interval and participants received echocardiograms at year 25 (June 1, 2010, to August 31, 2011). Data analysis was conducted from June 7, 1986, to August 31, 2011. Exposures Visit-to-visit systolic and diastolic BP variability measures included SD, average real variability, and variability independent of the mean. Main Outcomes and Measures Echocardiographic indices of myocardial structure, systolic function, and diastolic function at the year 25 examination. Results Of the 2400 participants, 1024 were men (42.7%) and 976 were African American (40.7%); mean (SD) age at the year 25 examination was 50.4 (3.6) years. Per 1-SD increment, greater visit-to-visit systolic BP variability independent of the mean was associated with higher left-ventricular (LV) mass index (β [SE], 2.66 [0.4] g/m2, P < .001), worse diastolic function (early peak diastolic mitral annular velocity [é]) (β [SE], -0.40 [0.1] cm/s, P < .001), higher LV filling pressures (mitral inflow velocity to early diastolic mitral annular velocity [E/é]) β [SE], 0.37 [0.1] cm/s, P < . 001), and worse global longitudinal strain (β [SE], 0.17 [0.1], P = .002). Similarly, greater visit-to-visit diastolic BP variability was associated with higher LV mass index (β [SE], 3.21 [0.5] g/m2, P < .001), worse diastolic function (é: β [SE], -0.24 [0.1] cm/s [P < .001]; E/é: β [SE], 0.23 [0.1] cm/s [P < .001]), and worse global longitudinal strain (β [SE], 0.13 [0.1], P = .02). The findings remained consistent when other BP variability measures were used (SD and average real variability). Conclusions and Relevance In this cohort study using data from the CARDIA study, greater visit-to-visit systolic and diastolic BP variability have been associated with adverse alterations in cardiac structure as well as systolic and diastolic function independent of mean BP levels.
Behavioural and socio-ecological factors that influence access and utilisation of health services by young people living in rural KwaZulu-Natal, South Africa: Implications for intervention

Background Young people’s health service utilisation (the number accessing a facility) has been the focus of guidelines and health systems strengthening policies. This is due to young people being at an increased health risk because of inequitable access and utilisation of health services, which is more pronounced in rural settings with limited service availability. This is a major concern as globally, youth constitute a considerable and increasing part of the population in Sub-Saharan Africa. Objective The objective of this paper is to present a comprehensive approach for the exploration of health service utilisation by young people in rural KwaZulu-Natal, South Africa. We examined barriers and facilitators conceptualised by the constructs of the Theory of Planned Behaviour, framed within a socio-ecological model. Methods Data were collected in January to June 2017 from two sites using in-depth interviews, spiral transect walks and community mapping with young people (aged 10 to 24 years), primary care health providers, school health professionals, community stakeholders and young people’s parents. Results Socio-ecological and behavioural factors influenced young people’s intention to use services. Barriers included perceived negative attitudes of health providers and perceived poor staff competencies. Facilitators included an appreciation of receiving health education and assumed improved health. At social and community levels, normative beliefs hindered young people from utilising services as they feared stigmatisation and gossip. At a public policy level, structural elements had a disempowering effect as the physical layout of the clinics hindered utilisation, limited resources influenced staffing, and facility opening times were not convenient for school goers. Conclusion We suggest that to fully appreciate the complexity of health service utilisation, it is necessary to not only consider factors and processes relevant to the individual, but also acknowledge and act upon, the disjuncture between community level cultural values, norms and national policies.
