REVIEW
Samantha Murphy, Joanne Cacciatore
This article reviews the current state of psychological, social, and economic research into the impact of stillbirth on families. We argue that whereas the knowledge we have of the experiential aspects of stillbirth is increasing, there is still much that remains to be uncovered especially in respect of the impact that seeing the baby may have on mental health. Moreover, the experience of particular social groups merits further work, most notably regarding same-sex couples and surrogates, mothers and fathers drawn from Black and Minority Ethnic groups as well as those from lower socio-economic groups...

INTRODUCTION: Previous studies demonstrated a high prevalence of cigarette smoking in patients presenting to the emergency department (ED) with acute asthma. Despite the clinical and public health importance, there have been no recent multicenter efforts to characterize this patient population. We aimed to update the prevalence of cigarette smoking among ED patients with asthma exacerbations. METHODS: Multicenter chart review study of 48 EDs across 23 US states...

BACKGROUND: Neonatal hyperbilirubinemia can be severe or prolonged and warrant exploration into the underlying etiology, which may include genetic assessment of UGT1A1 for inherited disorders (i.e. Crigler-Najjar syndrome or Gilbert syndrome). METHODS: In our reference laboratory, we performed UGT1A1 gene sequencing analysis on 346 pediatric patients referred for a clinical indication of hyperbilirubinemia. RESULTS: Males (n = 241) had significantly higher mean total bilirubin concentration compared to females (n = 105) (9...

PURPOSE: The ER-/PR-/HER2- or triple-negative (TNBC) subtype is more prevalent among women who are young, black, Hispanic, and of lower SES. The purpose of this study is to determine if young age and low SES are associated with TNBC within four mutually exclusive race/ethnicities. METHODS: The study identified 19,283 cases of TNBC and 89,089 of ER+/PR+/HER2- from the California Cancer Registry. Logistic regression analyses were conducted separately for whites, blacks, Hispanics, and Asian/Pacific Islanders (API) to compute the adjusted odds ratios (OR) for age and SES for the TNBC versus the ER+/PR+/HER2- subtype...

White rot fungi (WRF) are applicable to biodegradation of recalcitrant pollutants. However, excessive biomass growth typical for WRF cultivation can hinder their large scale applications. Therefore, immobilization of Irpex lacteus to liquid-core alginate beads restricting excessive mycelium growth and simultaneously keeping high degradation rate of pollutants was tested. Effective diffusivities of dyes to the beads varied from (2.98 ± 0.69) × 10(-10) to (10.27 ± 2.60) × 10(-10) m(2)/s. Remazol Brilliant Blue R (RBBR), Reactive Orange 16 (RO16), and Naphthol Blue Black (NBB) were used as model dyes...

African-born immigrants are among the fastest growing immigrant groups in the US, yet they are underrepresented in healthcare research, particularly, cancer research and tend to be categorized as African American or Black, obscuring any cultural nuances that exist. A survey designed to provide insight on the barriers to healthcare, knowledge of common cancers, and cancer risks was utilized during a health fair. Data analyses included descriptive statistics to examine participant demographics and other study variables of interest...

Historical records of Ateles chamek (black-faced black spider monkey) suggest that the species range extends further south of the known species distribution, within an ecotonal region between the Amazonia, Cerrado and Pantanal biomes in Brazil. Ecotones are zones of habitat transition with high species richness that remain undersampled as conservationists often prioritize biodiversity hotspots. Thus, distribution ranges may be inaccurately measured when species occur in ecotonal zones. We report the first precise records of A...

PURPOSE: During medical needle placement using image-guided navigation systems, the clinician must concentrate on a screen. To reduce the clinician's visual reliance on the screen, this work proposes an auditory feedback method as a stand-alone method or to support visual feedback for placing the navigated medical instrument, in this case a needle. METHODS: An auditory synthesis model using pitch comparison and stereo panning parameter mapping was developed to augment or replace visual feedback for navigated needle placement...

BACKGROUND: Obesity and poor sleep are highly prevalent among Black women. PURPOSE: We examined whether a weight gain prevention intervention improved sleep among Black women. METHODS: We conducted a randomized trial comparing a 12-month weight gain prevention intervention that included self-monitoring through mobile technologies and phone coaching to usual care in community health centers. We measured sleep using the Medical Outcomes Study Sleep Scale at baseline, 12 months, and 18 months...

BACKGROUND AND OBJECTIVES: The surveillance of children's growth reflects a population's nutritional status and risk for adverse outcomes. This study aimed to describe trends in length-for-age, weight-for-age, weight-for-length, and early childhood weight gain among US children aged 6 to 23 months. METHODS: We analyzed NHANES data from 1976-1980, 1988-1994, 1999-2002, 2003-2006, 2007-2010, and 2011-2014. We estimated z scores < -2 (low) and ≥+2 (high) in comparison with World Health Organization growth standards for each indicator...

In 1953, investigators at the Rocky Mountain Laboratories in Hamilton, Montana, described the isolation of a spotted fever group Rickettsia (SFGR) species from Dermacentor parumapertus collected from black-tailed jackrabbits (Lepus californicus) in northern Nevada. Several decades later, investigators characterized this SFGR by using mouse serotyping methods and determined that it represented a distinct rickettsial serotype, related closely to Rickettsia parkeri; nonetheless, the parumapertus agent was not further characterized or studied...

This study considers five important questions related to the role of race in state-level public support for the Medicaid expansion: (1) whether public support for the Medicaid expansion varies across the American states; (2) whether public support is positively related to state adoption; (3) whether this support is racialized; (4) whether, if racialized, there is evidence of more state responsiveness to white support than to nonwhite (black and/or Latino) support; and (5) does the size of the nonwhite population matter more when white support is relatively low? Our findings suggest that while public support for the Medicaid expansion is high at the state level, especially in comparison to public support for the ACA, there are important variations across the states...

A polydimethylsiloxane (PDMS)-based optical system has been demonstrated. To suppress intense background radiation due to multiple internal scatting in a transparent material, a composite structure of a carbon-PDMS compound and PDMS was proposed. The index matching of the real part of the refractive index can suppress internal scattering, and an absorption of 99-99.7% was attained by using carbon micro particles and carbon nano tubes. The black-PDMS light channel functions as a light filter for straight pass, and an optical density of 5 was obtained by bending the filter...

BACKGROUND AND AIMS: Response to sorafenib is highly variable in hepatocellular carcinoma (HCC). Baseline inflammatory parameters and treatment toxicities may improve survival prediction in patients on sorafenib therapy. RESULTS: 442 patients with advanced stage HCC on sorafenib were recruited (follow-up 5096 person-months at risk). 88% had BCLC stage B or greater HCC and 72.3% had Child-Pugh A cirrhosis. On Cox multivariate regression, previously-treated HCC (HR 0...

Exocrine pancreatic insufficiency (EPI) results in the maldigestion and malabsorption of nutrients. The digestive processes in humans and other monogastric species like rat and pig are characterized by a predominantly enzymatic digestion within the small intestine and microbial fermentation located in the hindgut. For protein, it is doctrine that only prececally absorbed amino acids can be transferred to the amino acid pool of the host, while postileal absorption of nitrogen-containing compounds occurs mainly in the form of ammonia, being a burden rather than a benefit for the organism...

Michael T Baglivio, Kevin T Wolff
While homicide perpetrated by juveniles is a relatively rare occurrence, between 2010 and 2014, approximately 7%-8% of all murders involved a juvenile offender. Unfortunately, few studies have prospectively examined the predictors of homicide offending, with none examining first-time murder among a sample of adjudicated male and female youth. The current study employed data on 5908 juvenile offenders (70% male, 45% Black) first arrested at the age of 12 or younger to prospectively examine predictors of an arrest for homicide/attempted homicide by the age of 18...

Overconsumption of energy dense foods and sedentary lifestyle are considered as major causes of obesity-associated insulin resistance and abnormal glucose metabolism. Results from both cohort studies and randomized trials suggested that anthocyanins from berries may lower metabolic risks, however these reports are equivocal. The present study was designed to examine effects of six berries with structurally diverse anthocyanin profiles (normalized to 400 µg/g total anthocyanin content) on development of metabolic risk factors in the C57BL/6 mouse model of polygenic obesity...

The obesity epidemic continues to affect millions of children and adolescents. Non-surgical options do not result in significant or sustained weight loss; thus bariatric surgery has become increasingly utilized. Limited data exist regarding safety for paediatric bariatric surgery, especially outside of National Institutes of Health (NIH)-funded centres. We hypothesized that the perioperative outcomes of paediatric patients undergoing laparoscopic sleeve gastrectomy (LSG) at our free-standing children's hospital would provide adequate safety profiles...

The magnetic reconnection process is analyzed for relativistic magnetohydrodynamical plasmas around rotating black holes. A simple generalization of the Sweet-Parker model is used as a first approximation to the problem. The reconnection rate, as well as other important properties of the reconnection layer, has been calculated taking into account the effect of spacetime curvature. Azimuthal and radial current sheet configurations in the equatorial plane of the black hole have been studied, and the case of small black hole rotation rate has been analyzed...
