SUMMARY ANSWER Maternal serum levels of 11-deoxycorticosterone (DOC) measured during the late first trimester or early second trimester correlate with an increased risk for preterm delivery prior to 32&nbsp;weeks, and the correlation becomes stronger when the ratio of DOC to 16-alpha-hydroxyprogesterone was measured. WHAT IS KNOWN ALREADY Progesterone is a pro-gestational steroid hormone that has been shown to decrease the risk of preterm birth in some pregnant women. Progesterone is metabolized by the body into various metabolites including members of the mineralocorticoid and glucocorticoid families. Our group has previously demonstrated that some progesterone metabolites enhance myometrial contractility in an ex vivo system, while others result in myometrial relaxation. The current exploratory study was designed to determine if pre-specified metabolion and Embryology.Background/purpose In recent years, treatment of heart failure patients has proved to benefit from implantation of pressure sensors in the pulmonary artery. Despite this, pulmonary artery pressure is related to the left ventricle, and cannot provide information on the right side of the heart. By contrast, pressure in the central venous system is directly connected to the right atrium and could potentially predict a wider range of heart failure conditions. The purpose of this work is to find an optimal site for implantation in the central venous system of a hemodynamic wireless sensor for heart failure monitoring. Since all previous hemodynamic sensors were located in the pulmonary artery, there is no existing information about an optimal site in the central venous system. Methods This study analysed data obtained from CT scans of most relevant anatomical features in the inferior vena cava. The most important parameters of the sites of interest were extracted, analysed statistically and compared, with the purpose to select an optimal site of implantation. Results The results obtained show that the area comprised between the iliac bifurcation and the lower renal vein (and between the second and third lumbar veins) is the most suitable site of implantation for a hemodynamic sensor. Parameters such as its straight anatomy, diameter (21&nbsp;mm) and link distance (106&nbsp;mm) present it as a convenient location for implantation. Its procedure appears relatively easy, as access from the femoral vein is close to the site of interest. In addition, there are not major delicate structure in its surroundings that may pose a risk to the patient. Conclusion This study concludes that the area between the iliac join and the lower renal vein (and the 2nd and 3rd lumbar veins) is an optimal site for the accommodation of a hemodynamic sensor. © 2020 The Authors.Objective Tobacco use is detrimental to physical and financial wellbeing. Smoking is associated with unemployment and a harder time finding re-employment. The current study examined job-seekers' prioritization of smoking over other discretionary items. Methods Adult, unemployed job-seekers smoking daily ranked items from 1 (highest) to 13 (lowest) for prioritization of their discretionary spending. The online survey randomly ordered the presentation of items. The Heaviness of Smoking Index (HSI, time to first cigarette and cigarettes per day) assessed severity of nicotine addiction. Results The sample (N&nbsp;=&nbsp;290) was 70% men, 42% African American and 30% non-Hispanic Caucasian, with mean age of 43 (SD&nbsp;=&nbsp;11), smoking an average of 12 cigarettes per day (SD&nbsp;=&nbsp;6), and 67% smoking within 30&nbsp;min of waking. Overall, cigarettes (M&nbsp;=&nbsp;4.7, SD&nbsp;=&nbsp;3.1) ranked second in importance behind only food (M&nbsp;=&nbsp;2.5, SD&nbsp;=&nbsp;2.7); 45% of the sample ranked tobacco in their top 3 spending priorities, and 26% ranked cigarettes as a higher priority than food. Cellular charges, transportation, grooming, and clothing ranked third through sixth, respectively. Higher HSI scores significantly correlated with greater prioritization of cigarettes (r&nbsp;=&nbsp;-0.25), and lower prioritization of food (r&nbsp;=&nbsp;0.16) and transportation (r&nbsp;=&nbsp;0.13), p's&nbsp; less then &nbsp;0.05. Conclusions Findings indicate cigarettes were highly prioritized, second only to food among job-seekers who smoke. Cigarettes were prioritized over job-seeking resources and health care, particularly among those who were more heavily addicted. Tobacco addiction can preempt basic life needs and reduce resources for finding re-employment. © 2020 The Authors.The rise of populist parties and movements in general and right-wing populist parties in particular has been noted also in the public health literature. While economic and other factors behind the populist surge have been systematically analyzed in the political and social science literature, the understanding of this political phenomenon seems weak in important parts of the public health literature. The lack of analysis of economic effects on health inequity of immigration of people with low levels of work skills to many high-income countries is given with the WHO Commission on Social Determinants of Health report as an example. Public health scholars should be able to fully analyze all effects on health inequity within countries. Public health scholars and professionals may lose credibility if they do not fully assess all relevant determinants, and the investigation of health inequity within countries should consider all systemic roots. [https://www.selleckchem.com/products/sn-011-gun35901.html Selleckchem SN-011] Health inequity between countries is a crucial issue and should be addressed through international cooperation between countries, regions and international organizations. The approach from political science and social science should be adopted. © 2020 Published by Elsevier Ltd.Background In the growing need of microvascular surgery in modern-day plastic surgery, financial burden on surgeon or institution can discourage acquisition of skill particularly in the initial phase of laboratory simulation. This article describes the construction of a cheap, easy-to-make blood vessel model. Materials and method The model was made using infusion giving set, latex glove, scissors, tape measure and Swan glue CD 308. A cut sheet from the latex glove was rolled twice over two glue-painted segment of the infusion giving set stent. The stents were gently pulled out, turning the sheet into a conduit. The blood vessel model was then allowed to dry. Discussion The use of latex glove for initial training in microvascular anastomosis has been for long. Previously described productions into a conduit are cumbersome. This model is easy to construct and is useful in an office or dry laboratory setting. Conclusion The latex glove blood vessel model described in this article is a useful material in the training of budding microsurgeons.
