INTRODUCTION: Food insecurity is a major global contributor to developmental origins of adult disease. The allostatic load of maternal food uncertainty from variable foraging demand (VFD) activates corticotropin-releasing factor (CRF) without eliciting hypothalamic-pituitary-adrenal (HPA) activation measured on a group level. Individual homeostatic adaptations of the HPA axis may subserve second-order homeostasis, a process we provisionally term "social allostasis." We postulate that maternal food insecurity induces a "superorganism" state through coordination of individual HPA axis response...

Microcystins are toxic peptides that can be produced by cyanobacteria in harmful algal blooms (HABs). Various analytical techniques have been developed to quantify microcystins in drinking water, including liquid chromatography tandem mass spectrometry (LC/MS/MS), enzyme linked immunosorbent assay (ELISA), and oxidative cleavage to produce 2-methyl-3-methoxy-4-phenylbutyric acid (MMPB) with detection by LC/MS/MS, the "MMPB method". Both the ELISA and MMPB methods quantify microcystins by detecting a portion of the molecule common to most microcystins...

REVIEW
Joshua M Rosenblum, Edward P Chen
Successful repair of complex thoracoabdominal aortic aneurysms requires careful surgical planning based on anatomic and patient considerations. Not only are surgical considerations key, but also post-operative care, regardless of surgical approach, can dramatically impact both short- and long-term outcomes. While open repair has been the gold standard for decades, the technical challenges associated with operative repair, a specialty approach requisite for good outcomes, and the unique challenges in the post-operative care of these patients have given providers pause when considering operative intervention...

The pathophysiology of neurodegenerative diseases is poorly understood and there are few therapeutic options. Neurodegenerative diseases are characterized by progressive neuronal dysfunction and loss, and chronic glial activation. Whether microglial activation, which is generally viewed as a secondary process, is harmful or protective in neurodegeneration remains unclear. Late-onset neurodegenerative disease observed in patients with histiocytoses, which are clonal myeloid diseases associated with somatic mutations in the RAS-MEK-ERK pathway such as BRAF(V600E), suggests a possible role of somatic mutations in myeloid cells in neurodegeneration...

Recent data suggest an increase in use of heroin and non-medical use of prescription opioids (POs) in the United States, but it is unclear if these trends are consistent across racial/ethnic groups. In a nationwide prevalence study, 69,140 patients newly admitted to an opioid treatment program (OTP) completed a brief self-administered survey of past month heroin use and PO misuse from January 2005 through September 2016. We calculated heroin use and PO misuse prevalence rates, and prevalence rate ratios of Black and Latino OTP entrants compared to White entrants over time...

Identifying extrapulmonary legionellosis is difficult due to the lack of clinical suspicion and limitations of conventional microbiologic methods. We present a case series of hematopoietic cell transplant recipients with extrapulmonary legionellosis diagnosed via molecular diagnostics: 16S ribosomal ribonucleic acid gene Sanger sequencing and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

Rising rates of overdose mortality underscore the importance of understanding and preventing overdose. We developed a seven-item scale for the assessment of nonfatal opioid-related overdose experiences, adding items on others' perceptions of whether the participant had overdosed and whether an intervention was attempted to frequently used criteria. We administered the scale to 240 primarily male and minority veterans, recruited using venue-based and chain-referral sampling, who separated from the military post-9/11 and reported current opioid use...

Celiac disease (CD) is a food-related chronic condition and adherence to a strict gluten-free diet is the only available treatment. Adherence to the restrictive diet is challenging among children, especially adolescents. The aim was to describe existing knowledge about food-related activities, participation, and quality of life in daily life among children and adolescents with CD and to illuminate gaps in knowledge. The scoping review methodology was applied and literature searches were conducted in electronic databases...

Amyotrophic lateral sclerosis (ALS) is a rapid and fatal neurodegenerative disease, primarily affecting upper and lower motor neurons. It is an extremely heterogeneous disease in both cause and symptom development, and its mechanisms of pathogenesis remain largely unknown. Excitotoxicity, a process caused by excessive glutamate signaling, is believed to play a substantial role, however. Excessive glutamate release, changes in postsynaptic glutamate receptors, and reduction of functional astrocytic glutamate transporters contribute to excitotoxicity in ALS...

Background: Diagnosis of leptomeningeal metastasis (LM) remains challenging due to low sensitivity of CSF cytology and infrequent unequivocal MRI findings. In a previous pilot study, we showed that rare cell capture technology (RCCT) could be used to detect circulating tumor cells (CTC) in the CSF of patients with LM from epithelial tumors. To establish the diagnostic accuracy of CSF-CTC in the diagnosis of LM, we applied this technique in a distinct, larger cohort of patients. Methods: In this institutional review board-approved prospective study, patients with epithelial tumors and clinical suspicion of LM underwent CSF-CTC evaluation and standard MRI and CSF cytology examination...

Physician-scientists are individuals who actively participate in patient care, have undergone additional research training, and devote the majority of their time to research. Physician-scientists are traditionally the primary catalysts in bridging the translational gap-that is, the failure to link fundamental new knowledge in the pathobiology of disease with advances in health care and health policy in a timely manner. However, there has been a shift away from training physician-scientists, and financial support for the physician-scientist is diminishing globally, causing the translational gap to grow...

A 51-year-old female who presented with obstructive jaundice was found to have masses in the pancreatic head and tail as well as suspicious liver and periaortic masses on imaging. Aspiration cytology of the pancreatic tail mass showed abundant large single cells with vacuolated eosinophilic cytoplasm, marked nuclear pleomorphism, large bizarre irregular nuclei, binucleation, and prominent nucleoli. Numerous cells also showed intracytoplasmic black to brown pigmentation. A cell block was obtained and extensive immunohistochemical staining was performed...

BACKGROUND: Studies of social media in both medicine and dentistry have largely focused on the value of social media for marketing to and communicating with patients and for clinical education. There is limited evidence of how dental clinicians contribute to and use social media to disseminate and access information relevant to clinical care. OBJECTIVE: The purpose of this study was to inventory and assess the entry, growth, sources, and content of clinically relevant social media in dentistry...

When are evolutionary outcomes predictable? Cases of convergent evolution can shed light on when, why, and how different species exhibit shared evolutionary trajectories. In particular, studying diverse species in a common environment can illuminate how different factors facilitate or constrain adaptive evolution. Here we integrate studies of pattern and process in the fauna at White Sands (New Mexico) to understand the determinants of convergent evolution. Numerous animal species at White Sands exhibit phenotypic convergence in response to a novel-and shared-selective environment: geologically young gypsum dunes...

OBJECTIVE: Translation of women's mental health research has yet to impact overall prevalence and burden of Mood Disorders in the United States. The lack of standard measures and methodological coordination across studies has contributed to the slow impact of research on outcomes. The primary aims of this project were to demonstrate the process by which multiple investigators, sites, and settings administered a standard women's mental health questionnaire within a new Women's Depression Network...

BACKGROUND: Programmed death 1 (PD-1) inhibition activates partially exhausted cytotoxic T lymphocytes (peCTLs) and induces tumor regression. We previously showed that the peCTL fraction predicts response to anti-PD-1 monotherapy. Here, we sought to correlate peCTL and regulatory T lymphocyte (Treg) levels with response to combination immunotherapy, and with demographic/disease characteristics, in metastatic melanoma patients. METHODS: Pretreatment melanoma samples underwent multiparameter flow cytometric analysis...

Khalid A Mohamedali, Michael G Rosenblum
Angiogenesis is a critical process in numerous diseases, and intervention in neovascularization has therapeutic value in several disease settings, including ocular diseases, arthritis, and in tumor progression and metastatic spread. Various vascular targeting agents have been developed, including those that inhibit growth factor receptor tyrosine kinases, blocking antibodies that interfere with receptor signal transduction, and strategies that trap growth factor ligands. Limited anti-tumor efficacy studies have suggested that the targeted delivery of the human pro-apoptotic molecule Granzyme B to tumor cells has significant potential for cancer treatment...

The persistence of shame-based reactions to child maltreatment (CM) has been associated with poor posttraumatic adjustment. Despite evidence that the postpartum period is a vulnerable time for women with CM histories, little is known about the consequences of maltreatment-specific (MS) shame for postpartum functioning. The current study examined individual differences in MS shame among a sample of women during the postpartum period ( n = 100) as well as prospective relations from MS shame to postpartum psychopathology at 6-, 12-, 15-, and 18-month postpartum...

REVIEW
Niwa Ali, Michael D Rosenblum
Foxp3+ CD4+ Regulatory T cells (Tregs) are a subset of immune cells that function to regulate tissue inflammation. Skin is one of the largest organs and is home to a large proportion of the body's Tregs. However, relative to other tissues (such as the spleen and gastrointestinal tract) the function of Tregs in skin is less well defined. Here, we review our understanding of how Tregs migrate to skin and the cellular and molecular pathways required for their maintenance in this tissue. In addition, we outline what is known about the specialized functions of Tregs in skin...
