Let's talk about sex:Exploring factors influencing the discussion of sexual health among chronically Ill patients in general practice

Background Chronic diseases are often associated with sexual dysfunction (SD). Little is known about the practice patterns of general practitioners (GPs) regarding sexual care for chronically ill patients. Therefore, the aim of this study was to examine; to what extent GPs discuss SD with chronically ill patients; the barriers that may stop them; and the factors associated with discussing SD. Methods A cross-sectional survey using a 58-item questionnaire was sent to 604 Dutch GPs. Descriptive statistics and associations were used for analysis of the data. Results Nearly 58% (n = 350) of all GPs approached gave a response and 204 questionnaires were analysable (33.8%). Almost 60% of respondents considered discussing SD with patients important (58.3%, n = 119). During the first consultation, 67.5% (n = 137) of the GPs reported that they never discussed SD. The most important barrier stopping them was lack of time (51.7%, n = 104). The majority (90.2%, n = 184) stated that the GP was responsible for addressing SD; 70.1% (n = 143) indicated that the GP practice somatic care nurse (GPN) was also responsible. Nearly 80% (n = 161) of respondents were unaware of agreements within the practice on accountability for discussing SD. This group discussed SD less often during first and follow-up consults (p = 0.002 and p < 0.001, respectively). Of the respondents, 61.5% (n = 116) felt that they had received insufficient education in SD and 74.6% (n = 150) stated that the subject is seldom discussed during training. Approximately 62% of the GPs (n = 123) wanted to increase their knowledge, preferably through extra training. According to 53.2% of the GPs (n = 107) it was important to improve the knowledge of the GPN. The most frequently mentioned tool that could help improve the conversation about SD was the availability of information brochures for patients (n = 123, 60.3%). Conclusions This study indicates that Dutch GPs do not discuss SD with chronically ill patients routinely, mainly due to lack of time. An efficient tool is needed to enable GPs to address SD in a time-saving manner. Increased availability of informational materials, agreements on accountability within GP practices, and extra training for the GPs and GPNs could improve the discussion of SD

Neighborhood Ethnic Diversity and Behavioral and Emotional Problems in 3 Year Olds: Results from the Generation R Study

Background:Studies suggest that neighborhood ethnic diversity may be important when it comes to understanding ethnic inequalities in mental health. The primary aim of this study was to investigate whether neighborhood ethnic diversity moderated the association between the ethnic minority status and child behavioral and emotional problems.Methods:We included 3076 preschoolers participating in the Generation R Study, a birth cohort study in Rotterdam, the Netherlands. At child age 3-years, parents completed the Child Behavior Checklist (CBCL/1,5-5). Individual-level data

Performance Testing of a Homemade Aerosol Generator for Pulmonary Administration of Dry Powder Formulations to Mice

A challenge in the development of dry powder formulations for inhalation is the poor reproducibility of their administration to small laboratory animals. The currently used devices for the pulmonary administration of dry powder formulations to small rodents often function sub-optimally as they use the same puff of air for both powder dispersion and aerosol delivery. As a result, either the air volume and flow rate are too low for complete powder deagglomeration or they are too high for effective aerosol delivery to the lungs of the animal. Therefore, novel and better devices are desired. We here present an aerosol generator designed to administer a pre-generated aerosol to the lungs of mice. By mapping the complex relationship between the airflow rate, delivery time and emitted dose, we were able to control the amount of powder being delivered from the aerosol generator. The emitted aerosol had a size range favorable for lung deposition and could be measured reproducibly. Nevertheless, in vivo fluorescent imaging still revealed considerable differences between the mice in terms of the dose deposited and the distribution of powder over the lungs, suggesting that a certain biological variation in lung deposition is inevitable.</p

Parallel ecological networks in ecosystems

In ecosystems, species interact with other species directly and through abiotic factors in multiple ways, often forming complex networks of various types of ecological interaction. Out of this suite of interactions, predator–prey interactions have received most attention. The resulting food webs, however, will always operate simultaneously with networks based on other types of ecological interaction, such as through the activities of ecosystem engineers or mutualistic interactions. Little is known about how to classify, organize and quantify these other ecological networks and their mutual interplay. The aim of this paper is to provide new and testable ideas on how to understand and model ecosystems in which many different types of ecological interaction operate simultaneously. We approach this problem by first identifying six main types of interaction that operate within ecosystems, of which food web interactions are one. Then, we propose that food webs are structured among two main axes of organization: a vertical (classic) axis representing trophic position and a new horizontal ‘ecological stoichiometry’ axis representing decreasing palatability of plant parts and detritus for herbivores and detrivores and slower turnover times. The usefulness of these new ideas is then explored with three very different ecosystems as test cases: temperate intertidal mudflats; temperate short grass prairie; and tropical savannah

52 Genetic Loci Influencing Myocardial Mass.

BACKGROUND: Myocardial mass is a key determinant of cardiac muscle function and hypertrophy. Myocardial depolarization leading to cardiac muscle contraction is reflected by the amplitude and duration of the QRS complex on the electrocardiogram (ECG). Abnormal QRS amplitude or duration reflect changes in myocardial mass and conduction, and are associated with increased risk of heart failure and death. OBJECTIVES: This meta-analysis sought to gain insights into the genetic determinants of myocardial mass. METHODS: We carried out a genome-wide association meta-analysis of 4 QRS traits in up to 73,518 individuals of European ancestry, followed by extensive biological and functional assessment. RESULTS: We identified 52 genomic loci, of which 32 are novel, that are reliably associated with 1 or more QRS phenotypes at p < 1 × 10(-8). These loci are enriched in regions of open chromatin, histone modifications, and transcription factor binding, suggesting that they represent regions of the genome that are actively transcribed in the human heart. Pathway analyses provided evidence that these loci play a role in cardiac hypertrophy. We further highlighted 67 candidate genes at the identified loci that are preferentially expressed in cardiac tissue and associated with cardiac abnormalities in Drosophila melanogaster and Mus musculus. We validated the regulatory function of a novel variant in the SCN5A/SCN10A locus in vitro and in vivo. CONCLUSIONS: Taken together, our findings provide new insights into genes and biological pathways controlling myocardial mass and may help identify novel therapeutic targets
