A Systematic Review of Biological Mechanisms of Fatigue in Chronic Illness

Fatigue, a commonly reported symptom, is defined as an overwhelming, debilitating, and sustained sense of exhaustion that decreases the ability to function and carry out daily activities. To date, cancer researchers have been in the forefront in investigating the possible biological mechanisms of fatigue, identifying inflammation, dysregulation of the hypothalamic–pituitary–adrenal (HPA) axis, and activation of the autonomic nervous system. The purpose of this systematic review is to describe fatigue and what is known about the biological mechanisms described in cancer in five chronic, noninfectious illnesses: heart failure, multiple sclerosis, chronic kidney disease, rheumatoid arthritis, and chronic obstructive pulmonary disease. We searched PubMed and EMBASE using fatigue as a major Medical subject headings (MeSH) heading with each individual disease added as a search term followed by each biological mechanism. We included only primary research articles published in English between 1996 and 2016 describing studies conducted in adult humans. We identified 26 relevant articles. While there is some evidence that the biological mechanisms causing fatigue in cancer are also associated with fatigue in other chronic illnesses, more research is needed to explore inflammation, the HPA axis, and the autonomic nervous system, and other mechanisms in relation to fatigue in a variety of chronic illnesses

Bedtime habits in adults with and without type 2 diabetes

This study aimed to identify determinants of objectively-estimated bedtime habits and to determine if these bedtime habits differed between adults with and without type 2 diabetes. Adults with accelerometry data from the National Health and Nutrition Examination Survey 2003-2004 and 2005-2006 cohorts were classified as having no diabetes or type 2 diabetes and matched for age, gender, and BMI across the two groups. Multivariate linear regression models assessed bedtime habits (time-in-bed, early versus late bedtime periods, regularity), chronotype (mid-points), and type 2 diabetes status. While the results indicated no differences in bedtime habits between adults with and without type 2 diabetes, an interesting finding was the support for an association between objectively-estimated earlier bedtime midpoints and greater physical activity

First trimester diagnosis and screening for fetal aneuploidy

Maternal serum screening for neural tube defects and fetal aneuploidy in the second trimester has been incorporated into obstetrical practice over the past two decades. Now, as a result of several multicenter trials, first trimester screening between 11 and 14 weeks has been shown to be an effective and reliable screening test for Down syndrome and trisomy 18. Benefits of first trimester screening include earlier identification of the pregnancy at risk for fetal aneuploidy and anatomic defects, in particular, cardiac anomalies, and the option of earlier diagnosis by chorionic villus sampling, if available. This policy updates the American College of Medical Genetics policy statement entitled Second Trimester Maternal Serum Screening for Fetal Open Neural Tube Defects and Aneuploidy (2004) and complements the sections of American College of Medical Genetic’s Standards and Guidelines for Clinical Genetics Laboratories entitled “Prenatal screening for Down syndrome that includes first trimester biochemistry and/or ultrasound measurements.

Increasing Maternal Body Mass Index and Characteristics of the Second Stage of Labor

To evaluate the length of the second stage of labor in relation to increasing maternal prepregnancy BMI among nulliparous parturients, and to determine whether route of delivery differs among obese, overweight, and normal weight women reaching the second stage

Brief of Amici Curiae 56 Professors of Law and Economics in Support of Petition of Writ of Certiorari

28 U.S.C. § 1400(b) provides that a defendant in a patent case may be sued where the defendant is incorporated or has a regular and established place of business and has infringed the patent. This Court made clear in Fourco Glass Co. v. Transmirra Prods. Corp., 353 U.S. 222, 223 (1957), that those were the only permissible venues for a patent case. But the Federal Circuit has rejected Fourco and the plain meaning of § 1400(b), instead permitting a patent plaintiff to file suit against a defendant anywhere there is personal jurisdiction over that defendant. The result has been rampant forum shopping, particularly by patent trolls. 44% of 2015 patent lawsuits were filed in a single district: the Eastern District of Texas, a forum with plaintiff-friendly rules and practices, and where few of the defendants are incorporated or have established places of business. And an estimated 86% of 2015 patent cases were filed somewhere other than the jurisdictions specified in the statute. Colleen V. Chien & Michael Risch, Recalibrating Patent Venue, Santa Clara Univ. Legal Studies Research Paper No. 10-1 (Sept. 1, 2016), Table 3. This Court should grant certiorari to review the meaning of 28 U.S.C. § 1400(b) because the Federal Circuit’s dubious interpretation of the statute plays an outsized and detrimental role, both legally and economically, in the patent system
