An assessment of the Midwest climate adaptation network: A call for improved coordination and collaboration.

Climate adaptation and the management of climate impacts require cross-sectoral and regional coordination and collaboration, but presently there is no thorough assessment of the adaptation network in the Midwest United States to evaluate how well it achieves such collaboration. We investigated the climate adaptation network across the Midwest to inform the strategic agenda for a climate adaptation boundary organization in Minnesota - the University of Minnesota Climate Adaptation Partnership (MCAP). We identified 150 organizations and more than 500 unique connections between them.

Pseudoclitoromegaly from acute T-cell lymphoblastic leukemia.

A 7-year-old girl presented with painful genital enlargement, which was first believed to be clitoromegaly of hormonal origin. However, on the physical exam the clitoris was not visible and the prepuce and labia minora were enlarged and tender. Magnetic resonance imaging demonstrated an infiltrative abnormal signal with restricted diffusion involving the enlarged clitoris and adjacent soft tissues of the prepuce and labia minora, confirming a nonhormonal infiltrative malignancy.

Refractory rhabdomyolysis responsive to corticosteroid therapy.

Rhabdomyolysis is a severe form of myopathy and a relatively common condition affecting the pediatric population. Early and aggressive intravenous volume expansion remains the mainstay of rhabdomyolysis treatment in both children and adults to minimize potential serious complications, including heme-induced acute kidney injury and metabolic abnormalities. We describe a 15-year-old boy with a previous hospital admission for rhabdomyolysis who presented with tea-colored urine, muscle cramps, and weakness with significant elevation of creatinine kinase (CK) following a viral illness.

Bacteremia in Early Infancy: Etiology and Management.

We reviewed the literature regarding bacteremia in early infancy (age ≤ 90 days). Bacteremia remains a major cause of morbidity and mortality in young infants. However, recent epidemiologic data suggest that the incidence of bacteremia is decreasing and the pathogens responsible for invasive disease are changing.

Quantitation of cannabinoid CB1 receptors in healthy human brain using positron emission tomography and an inverse agonist radioligand.

[11C]MePPEP is a high affinity, CB1 receptor-selective, inverse agonist that has been studied in rodents and monkeys. We examined the ability of [11C]MePPEP to quantify CB1 receptors in human brain as distribution volume calculated with the "gold standard" method of compartmental modeling and compared results with the simple measure of brain uptake. A total of 17 healthy subjects participated in 26 positron emission tomography (PET) scans, with 8 having two PET scans to assess retest variability.

In vivo 13C magnetic resonance spectroscopy of human brain on a clinical 3 T scanner using [2-13C]glucose infusion and low-power stochastic decoupling.

This study presents the detection of [2-(13)C]glucose metabolism in the carboxylic/amide region in the human brain, and demonstrates that the cerebral metabolism of [2-(13)C]glucose can be studied in human subjects in the presence of severe hardware constraints of widely available 3 T clinical scanners and with low-power stochastic decoupling. In the carboxylic/amide region of human brain, the primary products of (13)C label incorporation from [2-(13)C]glucose into glutamate, glutamine, aspartate, gamma-aminobutyric acid, and N-acetylaspartate were detected. Unlike the commonly used alkanyl region where lipid signals spread over a broad frequency range, the carboxylic carbon signal of lipids was found to be confined to a narrow range centered at 172.

Decreased neurokinin-1 (substance P) receptor binding in patients with panic disorder: positron emission tomographic study with [18F]SPA-RQ.

Background: Positron emission tomography (PET) can localize and quantify neurokinin-1 (NK(1)) receptors in brain using the nonpeptide antagonist radioligand, [(18)F]SPA-RQ. We sought to determine if patients with panic disorder have altered density of NK(1) receptors in brain because of their history of recurrent panic attacks. We also sought to determine if a drug-induced panic attack releases substance P in brain, as measured by decreased binding of [(18)F]SPA-RQ.

Kinetic analysis in healthy humans of a novel positron emission tomography radioligand to image the peripheral benzodiazepine receptor, a potential biomarker for inflammation.

The peripheral benzodiazepine receptor (PBR) is upregulated on activated microglia and macrophages and thereby is a useful biomarker of inflammation. We developed a novel PET radioligand, [(11)C]PBR28, that was able to image and quantify PBRs in healthy monkeys and in a rat model of stroke. The objective of this study was to evaluate the ability of [(11)C]PBR28 to quantify PBRs in brain of healthy human subjects.
