Childhood Lead Exposure Linked to Apple Cinnamon Fruit Puree Pouches - North Carolina, June 2023-January 2024.

Lead exposure is toxic even at low levels, resulting in impairments that can affect a child's lifelong success. In North Carolina, testing for lead is encouraged for all children at ages 1 and 2 years and required for children covered by Medicaid; investigations are performed to identify potential exposure sources for children with blood lead levels (BLLs) ≥5 μg/dL. During June-August 2023, routine lead testing identified four asymptomatic North Carolina children with BLLs ≥5 μg/dL.

The Small-Molecule Enhancers of Autophagy AUTEN-67 and -99 Delay Ageing in Striated Muscle Cells.

Autophagy (cellular self-degradation) plays a major role in maintaining the functional integrity (homeostasis) of essentially all eukaryotic cells. During the process, superfluous and damaged cellular constituents are delivered into the lysosomal compartment for enzymatic degradation. In humans, age-related defects in autophagy have been linked to the incidence of various age-associated degenerative pathologies (e.

Neural stem cells deriving from chick embryonic hindbrain recapitulate hindbrain development in culture.

Neural stem cells (NSCs) are self-renewing multipotent cells that line the neural-tube and generate all the nervous system. Understanding NSC biology is fundamental for neurodevelopmental research and therapy. Many studies emphasized the need to culture NSCs, which are typically purified from mammalian embryonic/adult brains.

The small molecule AUTEN-99 (autophagy enhancer-99) prevents the progression of neurodegenerative symptoms.

Autophagy functions as a main route for the degradation of superfluous and damaged constituents of the cytoplasm. Defects in autophagy are implicated in the development of various age-dependent degenerative disorders such as cancer, neurodegeneration and tissue atrophy, and in accelerated aging. To promote basal levels of the process in pathological settings, we previously screened a small molecule library for novel autophagy-enhancing factors that inhibit the myotubularin-related phosphatase MTMR14/Jumpy, a negative regulator of autophagic membrane formation.

AUTEN-67 (Autophagy Enhancer-67) Hampers the Progression of Neurodegenerative Symptoms in a Drosophila model of Huntington's Disease.

Background: Autophagy, a lysosome-mediated self-degradation process of eukaryotic cells, serves as a main route for the elimination of cellular damage [1-3]. Such damages include aggregated, oxidized or misfolded proteins whose accumulation can cause various neurodegenerative pathologies, including Huntington's disease (HD).

Objective: Here we examined whether enhanced autophagic activity can alleviate neurophatological features in a Drosophila model of HD (the transgenic animals express a human mutant Huntingtin protein with a long polyglutamine repeat, 128Q).

AUTEN-67, an autophagy-enhancing drug candidate with potent antiaging and neuroprotective effects.

Autophagy is a major molecular mechanism that eliminates cellular damage in eukaryotic organisms. Basal levels of autophagy are required for maintaining cellular homeostasis and functioning. Defects in the autophagic process are implicated in the development of various age-dependent pathologies including cancer and neurodegenerative diseases, as well as in accelerated aging.

Brain magnetic resonance imaging findings in patients with mucopolysaccharidosis VI.

Introduction: Mucopolysaccharidosis type VI (MPS VI) is a rare lysosomal storage disorder caused by the deficient activity of N-acetylgalactosamine 4-sulfatase. MPS VI is usually considered as not being associated with mental retardation.

Aims/methods: The main objective of the present study was to describe brain magnetic resonance imaging (MRI) findings and their correlation with clinical and biochemical findings in MPS VI patients.

Intrathyroidal thymic tissue mimicking a thyroid nodule in a 4-year-old child.

A 4 year-old girl was referred for CT of her neck for suspected submental lymphadenopathy and was found to have an incidental low-attenuation thyroid mass. Subsequent thyroid ultrasound showed a heterogeneous thyroid mass with punctate areas of increased echogenicity. Cytologic examination was consistent with ectopic intrathyroidal thymic nodule.

Morphometric differences in the Heschl's gyrus of hearing impaired and normal hearing infants.

This study investigates the morphometry of Heschl's gyrus and its included primary auditory cortex (PAC) in hearing impaired (HI) and normal hearing (NH) infants. Fourty-two infants, age 8-19 months, with NH (n = 26) or hearing impairment (n = 16) were studied using high-resolution 3D magnetic resonance imaging. Gray matter (GM) and white matter (WM) volumes were obtained using software for automatic brain imaging segmentation to estimate the volume of each tissue within manually defined regions for the anterior portion of Heschl's gyrus (aHG) in each individual subject, transformed to an infant brain template space.

Risk factors for cardiovascular disease ten years after preeclampsia.

Context And Objective: Preeclampsia is a gestational disease that occurs mainly among nulliparous women after the 20th week of gestation, and frequently close to delivery. The effects of preeclampsia on women's blood pressure over the long term are still controversial. Patients with recurrent preeclampsia or preeclampsia in the early stages of pregnancy appear to present higher risk of hypertension.

Brain MRI in mucopolysaccharidosis: effect of aging and correlation with biochemical findings.

Objective: To investigate the influence of aging on conventional MRI and magnetic resonance spectroscopy (MRS) findings of mucopolysaccharidosis (MPS) patients and to test the correlation of enzyme levels, urinary glycosaminoglycans (GAG), and neuroimaging findings.

Methods: Sixty patients with MPS types I (n = 8), II (n = 31), IV-A (n = 4), and VI (n = 17) underwent T2, fluid-attenuated inversion recovery (FLAIR), and MRS of the brain. For analysis of MRI variables, we measured the normalized cerebral volume (NCV), CSF volume (NCSFV), ventricular volume (NVV), and lesion load (NLL) on FLAIR using semiautomated and automated segmentation techniques.

Correlation of MR imaging and MR spectroscopy findings with cognitive impairment in mucopolysaccharidosis II.

Background And Purpose: There are no reliable markers to predict neurologic outcome of patients with mucopolysaccharidosis (MPS) II. We hypothesized that brain MR imaging and MR spectroscopy are useful in depicting features related to cognitive impairment (CI) in MPS II.

Materials And Methods: Nineteen male patients with MPS II were included in this study.

[Bronchoscopic removal of foreign body from airway through tracheotomy or tracheostomy].

Objective: Most foreign bodies in the airway are removed by respiratory endoscopy. Rarely, the removal of the foreign body has to be performed through endoscopic control by tracheotomy or tracheostomy. This article reports three cases of foreign body removal in children performed by tracheal opening.

What is the variability between 2 consecutive cystometries in the same child?

Purpose: We compared the results of 2 cystometrograms (CMGs) performed during a single session in the same child to determine the variability between consecutive cystometries.

Materials And Methods: Subjects underwent 2 consecutive bladder fillings performed at the same rate and position. Maximum cystometric bladder capacity (CBC), pressure at CBC, leak point pressure, maximum flow rate, pressure at maximum flow, maximum voiding pressure, residual urine and pressure specific volumes (PSV) less than 20, 30 and 40 cm water were compared between studies.
