Encouraging comprehensive and consistent pharmacist education for provision of contraception.

Objectives: To initiate a call to action for community pharmacists and key stakeholders to encourage comprehensive and consistent education and certification for contraception services, especially in states where laws have been enacted for pharmacist prescribing of hormonal contraceptives.

Date Sources: Websites for several boards of pharmacy that have implemented pharmacist training for contraceptive prescribing.

Summary: From the authors' perspective of helping to implement laws that allow pharmacist prescribing of contraception in Oregon and Colorado, lessons learned have shown that it is better to have 1 consistent resource for pharmacist certification for the following reasons: 1) Boards of pharmacy are able to ensure patient safety because all pharmacists are providing the same level of care to every patient; 2) retail chain pharmacies and pharmacy managers are assured that all their pharmacists, regardless of state, are trained in a similar and appropriate manner; and 3) pharmacists can be reimbursed through medical insurance for the patient encounter because payers are able to identify and credential pharmacists who pass an approved and accredited certification program.

In vivo nitric oxide suppression of lipolysis in subcutaneous abdominal adipose tissue is greater in obese than lean women.

Mounting evidence suggests there is a reduced mobilization of stored fat in obese compared to lean women. It has been suggested that this decreased lipid mobilization may lead to, or perpetuate, the obese state; however, there may be a beneficial effect of reduced lipolysis, either by allowing for a sink of excess fatty acids, or by limiting a potentially harmful rise in interstitial and circulating fatty acid concentration. Nitric oxide (NO) may be responsible for a portion of the reduced in vivo rates of lipolysis in obese women because NO reduces adipose tissue lipolysis and adipose tissue nitric oxide synthase (NOS) mRNA is higher in obese than lean individuals.

Closing the door on pharma? A national survey of family medicine residencies regarding industry interactions.

Purpose: To assess the extent and type of interactions U.S. family medicine residencies permit industry to have with medical students and residents.

Ongoing beta-cell turnover in adult nonhuman primates is not adaptively increased in streptozotocin-induced diabetes.

Objective: β-Cell turnover and its potential to permit β-cell regeneration in adult primates are unknown. Our aims were 1) to measure β-cell turnover in adult nonhuman primates; 2) to establish the relative contribution of β-cell replication and formation of new β-cells from other precursors (defined thus as β-cell neogenesis); and 3) to establish whether there is an adaptive increase in β-cell formation (attempted regeneration) in streptozotocin (STZ)-induced diabetes in adult nonhuman primates.

Research Design And Methods: Adult (aged 7 years) vervet monkeys were administered STZ (45-55 mg/kg, n = 7) or saline (n = 9).

Outcomes of patients with esophageal cancer staged with [¹⁸F]fluorodeoxyglucose positron emission tomography (FDG-PET): can postchemoradiotherapy FDG-PET predict the utility of resection?

Purpose: To determine whether [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET) can delineate patients with esophageal cancer who may not benefit from esophagectomy after chemoradiotherapy.

Patients And Methods: We reviewed records of 163 patients with histologically confirmed stage I to IVA esophageal cancer receiving chemoradiotherapy with or without resection with curative intent. All patients received surgical evaluation.

Dual radiotracer analysis of cholinergic neuronal changes in prediabetic mouse pancreas.

Background: Pancreatic neuronal changes associated with beta cell loss in type 1 diabetes mellitus are complex, involving, in part, parasympathetic mechanisms to compensate for preclinical hyperglycemia. The parasympathetic neurotransmitter acetylcholine (ACh) mediates insulin release via M3 muscarinic receptors on islet beta cells. The vesicular ACh transporter (VAChT) receptor has been shown to be a useful marker of cholinergic activity in vivo.

Enhanced cholinergic response in pancreata of nonhuman primates with impaired glucose tolerance shown on [18F]fluorobenzyltrozamicol positron emission tomography.

Background: Islet cell adaptation to insulin resistance in type 2 diabetes mellitus may be due in part to increased stimulation of beta cells by the autonomic nervous system. The parasympathetic neurotransmitter acetylcholine (ACh) mediates insulin release via M3 muscarinic receptors on islet beta cells. The vesicular ACh transporter (VAChT) receptor correlates with cholinergic activity in vivo.

Left ventricular infarct size assessed with 0.1 mmol/kg of gadobenate dimeglumine correlates with that assessed with 0.2 mmol/kg of gadopentetate dimeglumine.

Objective: To determine myocardial infarct (MI) size during cardiovascular magnetic resonance at 1.5 Tesla using 0.1 mmol/kg body weight of gadobenate dimeglumine (Gd-BOPTA) and 0.

Prediction of cardiac events in patients with reduced left ventricular ejection fraction with dobutamine cardiovascular magnetic resonance assessment of wall motion score index.

Objectives: The purpose of this study was to assess the utility of dobutamine cardiovascular magnetic resonance (DCMR) results for predicting cardiac events in individuals with reduced left ventricular ejection fraction (LVEF).

Background: It is unknown whether DCMR results identify a poor cardiac prognosis when the resting LVEF is moderately to severely reduced.

Methods: Two hundred consecutive patients ages 30 to 88 (average 64) years with an LVEF View Article and Find Full Text PDF

Brain abnormalities detected on whole-body 18F-FDG PET in cancer patients: spectrum of findings.

Objective: The purpose of this article is to discuss and show examples of the PET appearance of common brain abnormalities that radiologists encounter when interpreting whole-body 18F-FDG PET examinations of cancer patients.

Conclusion: Knowledge of the PET appearance of various brain abnormalities can yield diagnostically relevant information in cancer patients. Detection of brain abnormalities on whole-body PET often requires adjusting window settings to reduce the intensity of normal brain FDG activity.

L-citrulline reduces time to exhaustion and insulin response to a graded exercise test.

Purpose: Oral L-arginine supplementation has been shown to improve treadmill time to exhaustion and resting insulin sensitivity in individuals with peripheral vascular disease and type 2 diabetes, respectively. Furthermore, L-citrulline supplementation increases plasma L-arginine concentration to a level higher than that achieved by oral L-arginine supplementation. The purpose of this investigation was therefore to determine whether time to exhaustion during a graded treadmill test, as well as plasma insulin and glucose profiles, could be improved with oral L-citrulline supplementation in healthy individuals.

Predictive value of 18-fluoro-deoxy-glucose-positron emission tomography (18F-FDG-PET) in the identification of responders to chemoradiation therapy for the treatment of locally advanced esophageal cancer.

Objective: To evaluate the utility of F-FDG-PET in predicting response to concomitant chemoradiation in locally-advanced esophageal cancer.

Summary Background Data: Approximately 25% of esophageal cancer patients experience a pathologic complete response (pCR) to preoperative chemoradiation therapy. Computed tomography, endoscopy, and endoscopic ultrasound are unable to identify patients experiencing a pCR.

Reversal of hypermetabolic brown adipose tissue in F-18 FDG PET imaging.

Objectives: With the increasing application of F-18-fluorodeoxyglucose (FDG) positron emission imaging, there has been an evolving appreciation for the range of normal variants and the realization that false-positives can lead to serious consequences.

Results: One of the most common causes of a false-positive study is the uptake of FDG in areas of hypermetabolic brown adipose tissue (HBAT). Areas of involvement are often spatially closely related to important lymph node groups in the neck, axilla, and upper mediastinum, making critical differentiation difficult, even with PET-CT.

Futility of fluorodeoxyglucose F 18 positron emission tomography in initial evaluation of patients with T2 to T4 melanoma.

Background: Evaluation of newly diagnosed patients with melanoma for metastasis is requisite to treatment planning. The reported diagnostic yield of whole-body conventional radiological imaging in initial staging of patients with melanoma is low. However, the diagnostic yield of positron emission tomography (PET) for distant metastases is unclear.

A prospective evaluation of the impact of 18-F-fluoro-deoxy-D-glucose positron emission tomography staging on survival for patients with locally advanced esophageal cancer.

Purpose: To determine the impact of 18-F-fluoro-deoxy-D-glucose positron emission tomography (FDG-PET) in the staging and prognosis of patients with locally advanced esophageal cancer (LAEC).

Methods And Materials: Between January 2000 and October 2004, all patients with LAEC evaluated in the Department of Radiation Oncology were considered for enrollment into a Phase II trial of preoperative chemoradiation. Entry required a staging whole-body FDG-PET scan.

Is parathyroid carcinoma indeed a lethal disease?

Background: Parathyroid carcinoma is a rare malignancy with a wide range of aggressiveness. There is no current staging system. Our primary aim was to review the presentation, diagnosis, surgical treatment, and outcomes of patients, with the goal of assessing the incidence of death related to parathyroid carcinoma.

The scintigraphic appearance of subcapsular parathyroid adenomas.

Purpose: Approximately 5 to 10% of parathyroid adenomas are located within the thin, fibrous capsule of the thyroid gland. These subcapsular adenomas can complicate minimally invasive parathyroidectomy. The small incision used in this procedure limits the view of the surgical bed.

Providing optimal preoperative localization for recurrent parathyroid carcinoma: a combined parathyroid scintigraphy and computed tomography approach.

Purpose: The incidence of parathyroid carcinoma is approximately 0.5% to 5% in patients with primary hyperparathyroidism. Recurrent parathyroid carcinoma is treated with surgical resection of all sites of disease to ameliorate systemic manifestations of hyperparathyroidism, primarily hypercalcemia.

Enhanced scintigraphic protocol required for optimal preoperative localization before targeted minimally invasive parathyroidectomy.

At our tertiary care institution, a targeted minimally invasive parathyroidectomy (MIP) is the preferred surgical procedure for primary hyperparathyroidism. Similar to unilateral neck exploration (UNE), preoperative scintigraphic localization of the adenoma in relation to the midline is required. However, in contrast to the abbreviated standard incision for UNE, 2 distinct incision sites, 1 medial and 1 lateral, are available on each side with MIP.

Asymmetric neuroimaging in Creutzfeldt-Jakob disease: a ruse.

Creutzfeldt-Jakob disease (CJD) causes diffuse neurological symptoms, but asymmetric lesions have been found on conventional magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI). Less often, position emission tomography (PET) scanning can also reveal asymmetric lesions in patients with CJD. Such imaging may mislead clinicians.

Experienced scintigraphers contribute to success of minimally invasive parathyroidectomy by skilled endocrine surgeons.

Minimally invasive parathyroidectomy (MIP) has become the preferred surgical treatment for selected patients diagnosed with primary hyperparathyroidism (PHPT) at our tertiary-care center. Preoperative scintigraphy establishes the position of a parathyroid adenoma, dictates the incision site, and can minimize incision size and consequent tissue dissection. We reviewed our database and sought to identify factors that led to discordant preoperative imaging and operative findings and to assess the effect of experience on these findings.
