    The latest report from the Dartmouth Atlas Project -- Improving Patient Decision-Making in Health Care, which was conducted in conjunction with the Foundation for Informed Medical Decision Making -- concludes that if physicians educated and listened to their patients more thoroughly, unwanted variation would decline." Investigators took an "in-depth look at medical conditions involving decisions for elective care in cases where the statistics don't recommend a single course of action." They found that much of the difference is attributable to "physicians' preferences, not differences in patient populations. But in cases of elective procedures, giving a patient a treatment he doesn't want is as much an error as wrong-site surgery," the co-author of the study said.


    February 24, 2011: WHEN IT COMES TO ELECTIVE SURGERY, LOCATION MATTERS.

    For Medicare patients with conditions for which surgery is an option, whether they undergo elective surgery depends largely on where they live and the clinicians they see, according to a report from the Dartmouth Atlas Project and the Foundation released February 24, 2011. The study, "Improving Patient Decision-Making in Health Care: A 2011 Dartmouth Atlas Report Highlighting Minnesota,"shows remarkably wide regional variations in elective surgery for Medicare patients with similar conditions. In addition to analyzing data on practice patterns, the report also advocates for shared decision-making, a process that helps patients understand their choices fully and allows them to share treatment decisions with their clinicians.

    Cellular and Molecular Specificity of Pituitary Gland Physiology

    The anterior pituitary gland plays a central role in the maintenance of homeostasis. Recent reviews in the field highlight the important roles of this gland in the regulation of the different endocrine axis. In recent years it has become increasingly evident that in addition to the multiple positive and negative external stimuli, the regulation within the pituitary gland is based on local interactions among pituitary cells and the integration of downstream signaling network and transcription factors.

    This review focuses on these important aspects of the integration of external and paracrine/autocrine pathways that contribute to the precise control of the functional outcome response and plasticity to environmental stimuli of the pituitary. Discussed herein is how these signals combine to regulate the anterior pituitary plasticity response to homeostatic and physiopathological conditions and highlight the molecular mechanisms involved to obtain an integrated and appropriate physiological response.

    [​IMG]

    General regulatory principle. Scheme of major regulatory principles of anterior pituitary hormone production.

    Hormone synthesis and release are under stimulatory and/or inhibitory control of hypothalamic, hypophysiotropic hormones which critically trigger pulsatility, diurnal rhythms, and life-long changes of anterior hormone production. The target products of the anterior pituitary hormones control their production through feedback mechanisms at the level of the pitutary but also through long-feedback control at the hypothalamic level. For most anterior pituitary hormones, intrapituitary ultrashort-feedback mechanisms have been described that may play a role in adaptive processes or in the fine-tuning of anterior pituitary hormone production.

    To adapt the pituitary hormone production to altered physiological demands or to physiopathological disturbances, many factors have been identified, which modify the hormone production either by affecting the hormone synthesis and secretion directly at the hypophysial level or by modifying the hypothalamic control or the feedback inhibition of anterior pituitary hormone production.

    Green lines indicate stimulation, red lines indicate inhibition, and black lines indicate stimulation or inhibition.


    Perez-Castro C, Renner U, Haedo MR, Stalla GK, Arzt E. Cellular and Molecular Specificity of Pituitary Gland Physiology. Physiological Reviews 2012;92(1):1-38. Cellular and Molecular Specificity of Pituitary Gland Physiology

    The anterior pituitary gland has the ability to respond to complex signals derived from central and peripheral systems. Perception of these signals and their integration are mediated by cell interactions and cross-talk of multiple signaling transduction pathways and transcriptional regulatory networks that cooperate for hormone secretion, cell plasticity, and ultimately specific pituitary responses that are essential for an appropriate physiological response. We discuss the physiopathological and molecular mechanisms related to this integrative regulatory system of the anterior pituitary gland and how it contributes to modulate the gland functions and impacts on body homeostasis.

    Evaluation And Treatment Of Erectile Dysfunction In The Aging Male

    [​IMG]

    Pathways leading to penile smooth muscle relaxation and erection. NO is released from nerve terminals in the corpus cavernosum in response to a neural stimulus and from the endothelium in response to the release of acetylcholine (ACh) and to the shear stress elicited by increased blood flow in the corporeal sinusoids. NO binds to soluble guanylate cyclase (sGC) and thereby activates this enzyme, which catalyses the breakdown of guanosine triphosphate (GTP) into cGMP. This pathway, the target of PDE5-inhibition, is depicted in green. Other pathways, which are initiated by PGE1, activate a G-protein (G)-coupled receptor, leading to activation of adenylil cyclase (AC), which catalyses the breakdown of adenosine triphosphate (ATP) into cyclic adenosine monophosphate (cAMP). This pathway, and thus target for intracavernosal injection of prostaglandin, is depicted in red. cGMP and cAMP activate protein kinase G and A, respectively, which modulate potassium and calcium channels in the cell membrane, and the inositol triphosphate receptor (IP3-R) and the calcium- ATPase pump in the membrane of the sarcoplasmatic reticulum (SR). These events lead to a lowering of the cytosolic calcium concentration, which causes dissociation of calcium from calmodulin. Calmodulin in turn dissociates from myosin light chain kinase, thus inactivating it in turn leading to smooth muscle relaxation, and ultimately, to penile tumescence.

    Before the 20th century, individuals often did not live beyond the reproductive years, and sexuality of the elderly was not an issue. However, in the current era it is known that as life expectancy improves, both men and women are seeking to preserve their sexuality into old age. While the appreciation of sexuality persists with aging, a decline in sexual activity is typically seen with, and can be attributed to both general health problems as well as specific sexual dysfunctions. Erectile dysfunction is the most frequently diagnosed sexual dysfunction in the older male population. This mini-review provides an overview of contemporary literature concerning epidemiology, pathophysiology, assessment and treatment of erectile dysfunction in the aging male.

    ScienceSeeker
    ScienceSeeker | Science News Aggregator

    What is ScienceSeeker?

    There are thousands of science blogs and news sites around the world, written by active scientists, journalists, professors, students, and interested laypeople. But until now, there hasn’t been a good way for readers to sort through all of them. There are dozens of blog collectives, many sites that organize some of the information in the blogs, but none that attempt to encompass the entire range of science reporting, analysis, and discussion taking place at an astonishing pace, worldwide.

    ScienceSeeker is a project of ScienceOnline designed to fill that void. We have collected over 1,100 blogs and other science news sources in one place, and invite you to submit even more. Our goal is to be the world’s most comprehensive aggregator of science discussions, all organized by topic.

    What ScienceSeeker Does

    This site is a work in progress. Blogs are categorized according to a fixed list of topics. You can see lists of posts from those blogs, but since many bloggers have wide-ranging interests, some of the topics might not quite fit. Ultimately we plan on categorizing not by blog, but by individual post. Already we have other ways of arranging posts as well: just the best posts, chosen by experts; posts about peer-reviewed research; popular posts on Twitter. Users can recommend posts and write notes explaining what they like about those posts.

    Biosynthesis Of Androgens

    The formation of the major hormone classes from cholesterol: P450scc, cholesterol side-chain cleavage; 3BetaHSD, 3Beta-hydroxysteroid dehydrogenase; P450c21, steroid 21 hydroxylase; P450c17alpha, steroid 17alpha hydroxylase/17,20 lyase; P450aldo, aldosterone synthase; P450c11, steroid 11 hydroxylase; 17 BetaHSD, 17 Beta-hydroxysteroid dehydrogenase; SRD5A1/5A2, steroid 5alpha reductase type 1/2; P450arom, aromatase.

    The backdoor pathway: within the adrenal gland, 17a -hydroxyl progesterone is reduced by 5alpha reductase then 3alpha reductase giving 5alpha -pregnane-3alpha,17alpha -diol-20-one, which is cleaved by the 17,20 lyase activity of CYP17A1 to androsterone.

    Once in the periphery androsterone is reduced by 17Beta-hydroxysteroid dehydrogenase yielding 5alpha-androstane-3alpha, 17Beta-diol, and subsequently metabolized by 3alpha hydroxysteroid dehydrogenase enzymes (such as 17Beta hydroxysteroid dehydrogenase) to DHT without testosterone or androstenedione as intermediaries.

    Statistics Done Wrong
    Statistics Done Wrong — Statistics Done Wrong

    The woefully complete guide. If you’re a practicing scientist, you probably use statistics to analyze your data.

    From basic t tests and standard error calculations to Cox proportional hazards models and geospatial kriging systems, we rely on statistics to give answers to scientific problems.

    This is unfortunate, because most of us don’t know how to do statistics.

    Statistics Done Wrong is a guide to the most popular statistical errors and slip-ups committed by scientists every day, in the lab and in peer-reviewed journals.

    Many of the errors are prevalent in vast swathes of the published literature, casting doubt on the findings of thousands of papers.

    Statistics Done Wrong assumes no prior knowledge of statistics, so you can read it before your first statistics course or after thirty years of scientific practice.

    Dive in: the whole guide is available online!
