Our experiments demonstrate the existence of an optimal cardinality of the parcellation to capture local gradients of functional maps.Previous studies have shown that individuals with overweight and obesity may experience attentional biases and reduced inhibition toward food stimuli. However, evidence is scarce as to whether the attentional bias is present even before stimuli are consciously recognized. Moreover, it is not known whether or not differences in the underlying brain morphometry and connectivity may co-occur with attentional bias and impulsivity towards food in individuals with different BMIs. To address these questions, we asked fifty-three participants (age M = 23.2, SD = 2.9, 13 males) to perform a breaking Continuous Flash Suppression (bCFS) task to measure the speed of subliminal processing, and a Go/No-Go task to measure inhibition, using food and nonfood stimuli. We collected whole-brain structural magnetic resonance images and functional resting-state activity. A higher BMI predicted slower subliminal processing of images independently of the type of stimulus (food or nonfood, p = 0.001, εp2 = 0.17). This higher threshol-level sensory integration, and reward. At a late, conscious stage of visual processing a higher BMI is associated with a specific bias towards food and with lower GM density in reward brain regions. Finally, independently of BMI, volumetric variations and connectivity patterns in different brain regions are associated with variability in bCFS and Go/No-Go performances.Multi-modal neuroimaging projects such as the Human Connectome Project (HCP) and UK Biobank are advancing our understanding of human brain architecture, function, connectivity, and their variability across individuals using high-quality non-invasive data from many subjects. Such efforts depend upon the accuracy of non-invasive brain imaging measures. However, 'ground truth' validation of connectivity using invasive tracers is not feasible in humans. Studies using nonhuman primates (NHPs) enable comparisons between invasive and non-invasive measures, including exploration of how "functional connectivity" from fMRI and "tractographic connectivity" from diffusion MRI compare with long-distance connections measured using tract tracing. Our NonHuman Primate Neuroimaging & Neuroanatomy Project (NHP_NNP) is an international effort (6 laboratories in 5 countries) to (i) acquire and analyze high-quality multi-modal brain imaging data of macaque and marmoset monkeys using protocols and methods adapted from the HCP; (iimproved cortical and subcortical areal atlases by combining histological and imaging methods. Finally, we are collecting genetic and sociality-associated behavioral data in all animals in an effort to understand how genetic variation shapes the connectome and behavior.
To describe the number of admissions of pregnant adolescents to US juvenile residential systems (JRS) and the outcomes of pregnancies that ended while in custody.
Prospective study.
Three nonrandomly selected JRS in 3 US states.
Designated reporter at each JRS reporting aggregate data on various pregnant admissions, outcomes, and systems' policies.
None.
Monthly number of pregnant people admitted, pregnant people at the end of the month, births, preterm births, cesarean deliveries, miscarriages, induced abortions, ectopic pregnancies, maternal and newborn deaths, and administrative policies.
There were 71 admissions of pregnant adolescents reported over 12 months from participating JRS. At the time of the census, 6 of the 183 female adolescents (3.3%) were pregnant. Eight pregnancies ended while in custody. check details Of these, 1 pregnancy was a live full-term birth, 4 were miscarriages, and 3 were induced abortions. There were no newborn deaths or maternal deaths. Administrative policies and services variarceration.
Rhabdomyosarcomas (RMSs) of the female genital tract (FGT) have been recently shown to be associated with germline pathogenic variation in DICER1, which can underlie a tumor predisposition disorder. We sought to determine the incidence of a pathogenic variation in DICER1 in a cohort of RMSs of the FGT, as well as to evaluate the clinicopathological features and outcomes of the patients. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES We retrospectively reviewed medical records of the patients diagnosed with RMS of the FGT between 1990 and 2019. Molecular genetic sequencing of the tumor to detect an RNase IIIb domain hot spot mutation in DICER1 samples was performed in 7 patients. Individuals with a missense mutation in the tumor were also screened for a loss of function germline mutation in DICER1.
Of 210 cases of pediatric RMS, 11 arose from the FGT. Molecular genetic sequencing of the tumor samples revealed a somatic missense mutation in the RNase IIIb domain of DICER1 in a total of 3 patients, 2 patients with embryonal RMS of the cervix/uterus, and 1 patient with ovarian embryonal RMS. As a result of genetic testing for the loss of function germline mutation in DICER1, a heterozygous pathogenic variant was also found in 2 of these patients.
Despite the limited number of patients, our findings suggest that it is important to be aware of the possible association between RMS of FGT and pathogenic germline DICER1 variants because the detection of this mutation in a patient or relatives can provide the opportunity for surveillance of related conditions that might improve long-term outcomes and survival.

Lipomatous tumors of the vulva are exceedingly rare, particularly in adolescents. We describe the work-up and management of an adolescent girl who presented with a large, well-vascularized vulvar mass.
A 14-year-old girl presented with a large vulvar mass of unclear etiology. Magnetic resonance imaging of this mass revealed an ill-defined, well-vascularized mass with fat signal characteristics suggestive of a lipomatous tumor that was concerning for malignancy. We performed complete resection of the mass, and histologic evaluation revealed a vulvar hibernoma. There have been no signs of recurrence 1 year later.
Although rare, a hibernoma of the vulvar region may present in adolescence and may be concerning for malignancy on imaging. Complete resection of these tumors is recommended for definitive diagnosis and treatment.
