BACKGROUND: Concerns regarding vaccine safety and pain have prompted certain parents to limit the number of shots their child receives per visit. We estimated the prevalence of shot-limited children in Michigan, described their characteristics, assessed whether shot-limited children were up-to-date on recommended vaccinations, and investigated possible intervention points for vaccination education. METHODS: We analyzed vaccination registry and birth record data of children born in Michigan during 2012 who had ⩾2 vaccination visits, with ⩾1 visits after age 5months...

To understand how excitable tissues give rise to arrhythmias, it is crucially necessary to understand the electrical dynamics of cells in the context of their environment. Multicellular monolayer cultures have proven useful for investigating arrhythmias and other conduction anomalies, and because of their relatively simple structure, these constructs lend themselves to paired computational studies that often help elucidate mechanisms of the observed behavior. However, tissue cultures of cardiomyocyte monolayers currently require the use of neonatal cells with ionic properties that change rapidly during development and have thus been poorly characterized and modeled to date...

Yingqi Zhang, Terry Harrison
Gigantopithecus blacki is the largest hominoid that ever lived. The consensus view is that it is a specialized pongine and late-surviving member of the Sivapithecus-Indopithecus lineage. It is known primarily from Early and Middle Pleistocene cave sites in southern China, dating from 2.0 Ma to almost 300 ka. The cause of its extinction in the late Middle Pleistocene is unknown, but ecological change or the arrival of Homo erectus may have been contributing factors. Gigantopithecus is highly specialized in its dentognathic anatomy, with a unique combination of features that distinguish it from all other hominoids...

The World Trade Center (WTC) disaster released large amounts of various chemical substances into the environment, including perfluoroalkyl substances (PFASs). Yet, no studies have examined exposures in children living or attending schools near the disaster site. We measured serum PFASs in WTC Health Registry (WTCHR) respondents who were ≤8 years of age on September 11, 2001 and a sociodemographically-matched comparison group. We also examined the relationship of PFASs levels with dust cloud exposure; home dust exposure, and with traumatic exposure, the latter to take into account differences related to possible mental health consequences and associated behavioral problems...

BACKGROUND: Smoking cessation may lead to depression in some smokers and result in increased risk of suicide. OBJECTIVE: To compare the risk of suicide attempts/behaviors associated with different smoking cessation medications among schizophrenic patients. METHODS: A retrospective cohort study was conducted using General Electric (GE) medical record database (1995-2011). The first day of being prescribed a smoking cessation medication defined as index date...

BACKGROUND: The vaginal microbiome is an important site of bacterial-mammalian symbiosis. This symbiosis is currently best characterized for humans, where lactobacilli dominate the microbial community and may help defend women against infectious disease. However, lactobacilli do not dominate the vaginal microbiota of any other mammal studied to date, raising key questions about the forces that shape the vaginal microbiome in non-human mammals. RESULTS: We used Illumina sequencing of the bacterial 16S rRNA gene to investigate variation in the taxonomic composition of the vaginal microbiota in 48 baboons (Papio cynocephalus), members of a well-studied wild population in Kenya...

Chengsan Sun, Edith Hummler, David L Hill
: Neuronal activity plays a key role in the development of sensory circuits in the mammalian brain. In the gustatory system, experimental manipulations now exist, through genetic manipulations of specific taste transduction processes, to examine how specific taste qualities (i.e., basic tastes) impact the functional and structural development of gustatory circuits. Here, we used a mouse knock-out model in which the transduction component used to discriminate sodium salts from other taste stimuli was deleted in taste bud cells throughout development...

: Neural representations of approximate numerical value, or numerosity, have been observed in the intraparietal sulcus (IPS) in monkeys and humans, including children. Using functional magnetic resonance imaging, we show that children as young as 3-4 years old exhibit neural tuning to cardinal numerosities in the IPS and that their neural responses are accounted for by a model of numerosity coding that has been used to explain neural responses in the adult IPS. We also found that the sensitivity of children's neural tuning to number in the right IPS was comparable to their numerical discrimination sensitivity observed behaviorally, outside of the scanner...

The nature of hematopoietic stem cells under normal hematopoiesis remained largely unknown due to the limited assays available to monitor their behavior in situ. Here, we develop a new mouse model to transfer genes specifically into the primitive hematopoietic stem cell compartment through the utilization of a modified Rcas/TVA system. We succeeded in transferring a GFP reporter gene into adult hematopoietic stem cells in vivo, which are predominantly quiescent, by generating pseudotyped-lentivirus. Furthermore, we demonstrate the utility of this system to study neonatal hematopoiesis, a developmental stage that has been difficult to analyze to date...

BACKGROUND: Electronic cigarettes (e-cigarettes) are a consumer product whose benefits and risks are currently debated. Advocates of the "tobacco harm reduction" strategy emphasize their potential as an aid to smoking cessation, while advocates of the precautionary principle emphasize their risks instead. There have been only a few studies to date on the prevalence of e-cigarette use in Germany. METHODS: In May 2016, in collaboration with Forsa, an opinion research firm, we carried out a survey among 4002 randomly chosen persons aged 14 and older, asking them about their consumption of e-cigarettes with and without nicotine, reasons for using e-cigarettes, plans for future use, estimation of danger compared to that of tobacco products, smoking behavior, and sociodemographic features...

Skin injuries are the most common type of injuries occurring in day-to-day life. A skin injury usually manifests itself in the form of a wound or a cut. While a shallow wound may heal by itself within a short time, deep wounds require surgical interventions such as suturing for timely healing. To date, suturing practices are based on a surgeon's experience and may vary widely from one situation to another. Understanding the mechanics of wound closure and suturing of the skin is crucial to improve clinical suturing practices and also to plan automated robotic surgeries...

Both impulsivity and sleep disturbance have been associated with heavy alcohol use among young adults; yet studies to date have not examined their interactive effects. The current study aimed to determine if adequate sleep moderates the association between impulsive personality traits and alcohol use among young adults. College students (N = 568) who had been mandated to alcohol treatment following violation of campus alcohol policy provided information regarding alcohol use and related consequences, impulsive personality traits (measured using the UPPS Impulsive Behavior Scale), and perception of sleep adequacy as part of a larger intervention trial...

Understanding the interrelation among problem behaviors and their change over time is fundamental for prevention research. The Healthy Teens Longitudinal Study followed a cohort of adolescents from Grades 6-12. Prior research identified two distinct trajectories of perpetration of physical dating violence: Low and Increasing. The purpose of this study was to examine whether adolescents in these two trajectories differed longitudinally on other problem behaviors: (1) suicidal ideation and attempts, (2) weapon-carrying and threats with a weapon, and (3) substance use, particularly alcohol and marijuana...

In mammals, a master circadian clock within the suprachiasmatic nucleus (SCN) of the hypothalamus maintains the phase coherence among a wide array of behavioral and physiological circadian rhythms. Affective disorders are typically associated with disruption of this fine-tuned "internal synchronization," but whether this internal misalignment is part of the physiopathology of mood disorders is not clear. To date, depressive-like behavior in animal models has been induced by methods that fail to specifically target the SCN regulation of internal synchronization as the mode to generate depression...

BACKGROUND: Major depressive disorder (MDD) is one of the most prevalent mental health disorders and has a significant societal economic burden. Antidepressants and cognitive behavioral therapy are two primary interventions for the standardized treatment of MDD. However, their weaknesses, such as a low response rate, a high risk of adverse events from medication, and the high cost of cognitive behavioral therapy, have resulted in a need for complementary and alternative medicine (CAM)...

Distress tolerance is associated with a range of psychopathology and risk-taking behavior. Current research suggests that the behavioral ability to persist at goal-directed behavior when distressed may be malleable. However, little is known about the contributing factors that underlie individual differences in distress tolerance. Trait urgency, or the tendency to act impulsively in the context of acute changes in affect, may predict distress tolerance because the prepotent response to avoid or remove an aversive state may undermine persistence...

Throughout a marriage couples will share countless ordinary moments together that may seem trivial, but which actually have potential to affirm and strengthen relational bonds. According to theories of emotional capital, the accumulation of shared positive moments in a relationship should serve as an essential resource for protecting the relationship against threats. To date, however, few empirical studies have explored the role emotional capital may play in shaping responses to negative relationship experiences...

BACKGROUND: Change in cognitive ability is a commonly reported side effect by breast cancer survivors (BCS). The underlying etiology of cognitive complaints is unclear and to date there is limited evidence for effective intervention strategies. Exercise has been shown to improve cognitive function in older adults and animal models treated with chemotherapy. This proof-of-concept randomized controlled trial (RCT) tested the effect of aerobic exercise versus usual lifestyle on cognitive function in postmenopausal BCS...
