BACKGROUND: Postpartum depression (PPD) can result in negative personal and child developmental outcomes. Only a few large population-based studies of PPD have used clinical diagnoses of depression and no study has examined how a maternal depression history interacts with known risk factors. The objective of this study was to examine the impact of a depression history on PPD and pre- and perinatal risk factors. METHODS: A nationwide prospective cohort study of all women with live singleton births in Sweden from 1997 through 2008 was conducted...

The increasing number of treatment options and the high costs associated with epilepsy have fostered the development of economic evaluations in epilepsy. It is important to examine the availability and quality of these economic evaluations and to identify potential research gaps. As well as looking at both pharmacologic (antiepileptic drugs [AEDs]) and nonpharmacologic (e.g., epilepsy surgery, ketogenic diet, vagus nerve stimulation) therapies, this review examines the methodologic quality of the full economic evaluations included...

Objective Human resource primacy (HRP) refers to employees' perceptions of how the organization shows interests in its employees' welfare, happiness, and health. The aims of this study were to determine whether (i) perceptions of HRP are related to the risk for disability retirement and (ii) HRP moderates the impact of psychological distress on later risk for disability retirement. Methods The study relied on a combination of self-report survey questionnaire data on HRP and psychological distress supplemented with official register data on disability benefits from the Norwegian Labor and Welfare Administration...

Genes of the major histocompatibility complex (MHC) are a likely target of mate choice because of their role in inbreeding avoidance and potential benefits for offspring immunocompetence. Evidence for female choice for complementary MHC alleles among competing males exists both for the pre- and the postmating stages. However, it remains unclear whether the latter may involve non-random fusion of gametes depending on gametic haplotypes resulting in transmission ratio distortion or non-random sequence divergence among fused gametes...

A major factor in the resilience of Listeria monocytogenes is the alternative sigma factor B (σ(B)). Type II Toxin/Antitoxin (TA) systems are also known to have a role in the bacterial stress response upon activation via the ClpP or Lon proteases. Directly upstream of the σ(B) operon in L. monocytogenes is the TA system mazEF, which can cleave mRNA at UACMU sites. In this study, we showed that the mazEF TA locus does not affect the level of persister formation during treatment with antibiotics in lethal doses, but exerts different effects according to the sub-inhibitory stress added...

Transforming Growth Factor-β (TGF-β) signaling in cancer has been termed the "TGF-β paradox", acting as both a tumor suppresser and promoter. The complexity of TGF-β signaling within the tumor is context dependent, and greatly impacted by cellular crosstalk between TGF-β responsive cells in the microenvironment including adjacent epithelial, endothelial, mesenchymal, and hematopoietic cells. Here we utilize normal, weaning-induced mammary gland involution as a tissue microenvironment model to study the complexity of TGF-β function...

Brain metastases are highly-evolved manifestations of breast cancer arising in a unique microenvironment, giving them exceptional adaptability in the face of new extrinsic pressures. The incidence is rising in line with population ageing, and use of newer therapies that stabilise metastatic disease burden with variable efficacy throughout the body. Historically, there has been a widely-held view that brain metastases do not respond to circulating therapeutics because the blood-brain-barrier (BBB) restricts their uptake...

Seed germination is a complicated biological process that requires regulation through various enzymatic and non-enzymatic mechanisms. Although it has been recognized that reactive oxygen species (ROS) regulate radicle emergence and root elongation in a non-enzymatic manner during dicot seed germination, the role of ROS in monocot seed germination remains unknown. NADPH oxidases (NOXs) are the major ROS producers in plants; however, whether and how NOXs regulate rice seed germination through ROS generation remains unclear...

It is known that plant viruses can change the performance of their vectors. However, there have been no reports on whether or how a semipersistent plant virus manipulates the feeding behaviors of its whitefly vectors. Cucurbit chlorotic yellows virus (CCYV) (genus Crinivirus, family Closteroviridae) is an emergent plant virus in many Asian countries and is transmitted specifically by B and Q biotypes of tobacco whitefly, Bemisia tabaci (Gennadius), in a semipersistent manner. In the present study, we used electrical penetration graph (EPG) technique to investigate the effect of CCYV on the feeding behaviors of B...

Posttraumatic stress disorder (PTSD) represents one of the most common mental health disorders, particularly among veterans, and is associated with significant distress and impairment. This highly debilitating disorder is further complicated by common comorbid psychiatric disorders, such as substance use disorders (SUD). Individuals with PTSD and co-occurring SUD also commonly present with secondary symptoms, such as elevated depression. Little is known, however, about how these secondary symptoms are related to treatment outcome...

The skin serves as the foremost barrier between the internal body and the external world, providing crucial protection against pathogens and chemical, mechanical, and ultraviolet damages. The skin is a central player in the intricate network of immune, neurologic, and endocrine systems. The endocannabinoid system (ECS) includes an extensive network of bioactive lipid mediators and their receptors, functions to modulate appetite, pain, mood, and memory, and has recently been implicated in skin homeostasis. Disruption of ECS homeostasis is implicated in the pathogenesis of several prevalent skin conditions...

Scabies, an infectious disease caused by the scabies mite, manifests as an intensely pruritic skin rash. Children, the underprivileged, and patients with immunocompromise are at a higher risk of acquiring this contagious disease. Infectivity occurs worldwide in patients of all races, ages, and sex. The classical appearance of papular burrows between the webbed spaces of digits or along the wrists can help distinguish scabies from other dermatologic diseases. Practitioners need to be familiar with how scabies may present so that patients can be treated and taught how to prevent spread of the disease...

Diethylstilbestrol (DES) is a synthetic estrogen given to pregnant women to prevent miscarriages and preterm labor; the drug was used between 1941 and 1971 in the United States and into the 1980s in other countries. DES exposure is associated with significant long-term health effects, including increased risk for breast cancer, cervical and vaginal clear cell adenocarcinoma, reproductive tract abnormalities, infertility, poor pregnancy outcomes, and early menopause. This article reviews the potential health risks associated with DES exposure, how to assess which patients are at risk, and management recommendations for patients exposed to DES...

Nalini M Nadkarni
On July 3, 2015, Nalini Nadkarni, a world-renowned ecologist who had been studying the biologic processes of ecosystem disturbance and recovery, sustained a catastrophic 50-foot free-fall from the top of the rainforest canopy to the forest floor at her remote field research site. She lost consciousness in shock and sustained life-threatening injuries. Her accompanying students hiked out, radio-called 911, and the Harborview Medical Center (Seattle) Medivac team arrived 4 hours later to rescue her. Her prognosis was extremely grim; her family gathered in anticipation of her death as she underwent four operations during her 10 days in the ICU...

Over the past 20 years, critical care has matured in a myriad of ways resulting in dramatically higher survival rates for our sickest patients. For millions of new survivors comes de novo suffering and disability called "the postintensive care syndrome." Patients with postintensive care syndrome are robbed of their normal cognitive, emotional, and physical capacity and cannot resume their previous life. The ICU Liberation Collaborative is a real-world quality improvement initiative being implemented across 76 ICUs designed to engage strategically the ABCDEF bundle through team- and evidence-based care...

OBJECTIVE: Many patients are admitted to the ICU at or near the end of their lives. Consequently, the increasingly common debate regarding physician-assisted suicide and euthanasia holds implications for the practice of critical care medicine. The objective of this article is to explore core ethical issues related to physician-assisted suicide and euthanasia from the perspective of healthcare professionals and ethicists on both sides of the debate. SYNTHESIS: We identified four issues highlighting the key areas of ethical tension central to evaluating physician-assisted suicide and euthanasia in medical practice: 1) the benefit or harm of death itself, 2) the relationship between physician-assisted suicide and euthanasia and withholding or withdrawing life support, 3) the morality of a physician deliberately causing death, and 4) the management of conscientious objection related to physician-assisted suicide and euthanasia in the critical care setting...

Minimally invasive glaucoma surgery aims to provide a safer and less-invasive means of reducing IOP compared with traditional surgery, with the goal of reducing the need for topical medications. The XEN gel stent is an ab-interno minimally invasive glaucoma surgery device that approaches intraocular pressure reduction by creating a subconjunctival drainage pathway. As with any new device there is lack of experience and knowledge about its long-term results in terms of efficacy, technique, and complications...
