Impact of diet on the persistence of early vascular remodeling and stiffening induced by intrauterine growth restriction and a maternal high-fat diet.

Intrauterine growth restriction (IUGR) and maternal high-fat diet (HFD) independently predispose offspring to hypertension. In a rat model, IUGR more so than maternal HFD increases arterial stiffness with vascular remodeling as early as (PND) . The trajectory of such early vascular changes remains unknown.

Post-traumatic stress disorder and serum cytokine and chemokine concentrations in patients with rheumatoid arthritis.

Objective: Although post-traumatic stress disorder (PTSD) is identified as a risk factor in the development of rheumatoid arthritis (RA), associations of PTSD with disease progression are less clear. To explore whether PTSD might influence disease-related measures of systemic inflammation in RA, we compared serum cytokine/chemokine (cytokine) concentrations in RA patients with and without PTSD.

Methods: Participants were U.

Genetic landscape and novel disease mechanisms from a large LGMD cohort of 4656 patients.

Objective: Limb-girdle muscular dystrophies (LGMDs), one of the most heterogeneous neuromuscular disorders (NMDs), involves predominantly proximal-muscle weakness with >30 genes associated with different subtypes. The clinical-genetic overlap among subtypes and with other NMDs complicate disease-subtype identification lengthening diagnostic process, increases overall costs hindering treatment/clinical-trial recruitment. Currently seven LGMD clinical trials are active but still no gene-therapy-related treatment is available.

Improving the Insulin Pump Initiation Process for Pediatric Patients with Type 1 Diabetes through Application of Lean Quality Improvement Methods.

Context: Our pediatric diabetes center initiated insulin pump therapy for more than 250 patients with type 1 diabetes in 2014, but onboarding was inefficient.

Objective: To decrease time from the decision to initiate pump therapy to the ambulatory encounter after pump start (lead time) for new pump users from 132.5 days to less than 110 days within 5 months.

Leaving the emergency department without complete care: disparities in American Indian children.

Background: Children who leave the emergency department (ED) without complete evaluation or care (LWCET) have poorer outcomes in general. Previous studies have found that American Indian (AI) children have higher rates of LWCET than other racial or ethnic groups. Therefore, this study aims to examine LWCET in AI children by exploring differences by ED location and utilization patterns.

Community Perspectives on Emergency Department Use and Care for American Indian Children.

Emergency department (ED) utilization by American Indian (AI) children is among the highest in the nation. Numerous health disparities have been well documented in AI children, but limited information is available on parental experiences of care for AI children in the ED. Our objective was to understand parental attitudes towards ED care for AI children.

The Role of Bias by Emergency Department Providers in Care for American Indian Children.

Background: American Indian children have high rates of emergency department (ED) use and face potential discrimination in health care settings.

Objective: Our goal was to assess both implicit and explicit racial bias and examine their relationship with clinical care.

Research Design: We performed a cross-sectional survey of care providers at 5 hospitals in the Upper Midwest.

Quality of care and in-hospital outcomes in patients with coronary heart disease in rural and urban hospitals (from Get With the Guidelines-Coronary Artery Disease Program).

Previous studies have suggested that patients with coronary artery disease (CAD) in rural areas may have worse outcomes due to limited availability of specialists, fewer resources, and less institutional funding. Data were collected from hospitals participating in the Get With the Guidelines-Coronary Artery Disease Program (GWTG-CAD) from January 2000 to December 2008. In-hospital outcomes and quality of care were stratified by care at rural versus urban hospitals.

Insulation discontinuity in a vagus nerve stimulator lead: a treatable cause of intolerable stimulation-related symptoms.

Discontinuity in the silicone insulation over an electrode of a left vagus nerve stimulator (VNS) allowed the aberrant leak of current to the phrenic nerve and other structures. This resulted in ipsilateral diaphragmatic dysfunction, inability to vocalize, and severe radiating pain into the jaw and upper incisor for the duration of each stimulation. The device was explanted and a new device was implanted.

Toward DSM-V: an item response theory analysis of the diagnostic process for DSM-IV alcohol abuse and dependence in adolescents.

Objective: Item response theory analyses were used to examine alcohol abuse and dependence symptoms and diagnoses in adolescents. Previous research suggests that the DSM-IV alcohol use disorder (AUD) symptoms in adolescents may be characterized by a single dimension. The present study extends prior research with a larger and more comprehensive sample and an examination of an alternative diagnostic algorithm for AUDs.

Hepatic Trauma.

Hepatic injuries are one of the most common abdominal injuries following either blunt or penetrating trauma. CT scanning has revolutionized the treatment algorithm for these patients. The majority of patients are successfully treated with nonoperative management, but surgeons should have a clear understanding of the indications for operative intervention.

Complete duplication of bladder and urethra in a sagittal plane in a male infant: case report and literature review.

Complete duplication of the bladder and urethra is a rare entity. It may occur in the coronal and sagittal planes, and is often associated with other organ system anomalies, in particular of the gastrointestinal tract. We report an unusual variant of sagittal duplication of the bladder, in a male, associated with rudimentary hindgut duplication, and review the literature pertaining to this unusual anomaly.

The benefits of early androgen blockade.

Altering the effects of testosterone on prostate cancer cells by blocking androgen production or action is a critical part of treating this malignancy. The appropriate timing of androgen blockade for advanced prostate cancer is controversial. Despite many phase-III studies, gaps in clinical information still remain, and some questions are still not conclusively answered.

Infantile cardiomyopathy caused by the T14709C mutation in the mitochondrial tRNA glutamic acid gene.

A 6-week-old child presented with hypotonia, myopathy, and a rapidly worsening dilated cardiomyopathy with severe atrial and ventricular arrhythmias and pulmonary hypertension, which proved fatal at age 3 months. Biochemical analysis showed a combined deficiency of the enzymatic activities of complexes I and IV and molecular studies identified a T14709C mutation in the mitochondrial tRNA glutamic acid gene. A review of symptomatology in patients with this mutation shows that it mainly presents in childhood or young adults with mild myopathy and diabetes mellitus.

A one-session human immunodeficiency virus risk-reduction intervention in adolescents with psychiatric and substance use disorders.

Objective: To explore change in human immunodeficiency virus (HIV) risk among teens in outpatient treatment for substance use disorders (SUDs).

Method: From December 2002 to August 2004, 50 adolescents (13-19 years) with major depressive disorder, conduct disorder, and one or more non-nicotine SUD completed the Teen Health Survey (THS) at the beginning and end of 16 weeks of outpatient cognitive behavioral SUD treatment, which included a one-session HIV intervention. Changes in THS scale scores and specific item responses targeted by the intervention were assessed with paired t tests and Wilcoxon signed rank tests.

Regulation of the Pro-apoptotic scaffolding protein POSH by Akt.

POSH (Plenty of SH3 domains) binds to activated Rac and promotes apoptosis by acting as a scaffold to assemble a signal transduction pathway leading from Rac to JNK activation. Overexpression of POSH induces apoptosis in a variety of cell types, but apoptosis can be prevented by co-expressing the pro-survival protein kinase Akt. We report here that POSH is a direct substrate for phosphorylation by Akt in vivo and in vitro, and we identify a major site of Akt phosphorylation as serine 304 of POSH, which lies within the Rac-binding domain.

Clinical trials of xenotransplantation: waiver of the right to withdraw from a clinical trial should be required.

Xenotransplantation pits clinical research ethics against public health needs because recipients must undergo long-term, perhaps life-long, surveillance for infectious diseases. This surveillance requirement is effectively an abrogation of the right to withdraw from a clinical trial. Ulysses contracts, which are advance directives for future care, may be an ethical mechanism by which to balance public health needs against limitation of individual rights.

Adhesion-related kinase induction of migration requires phosphatidylinositol-3-kinase and ras stimulation of rac activity in immortalized gonadotropin-releasing hormone neuronal cells.

GnRH neurons migrate into the hypothalamus during development. Although migratory defects may result in disordered activation of the reproductive axis and lead to delayed or absent sexual maturation, specific factors regulating GnRH neuronal migration remain largely unknown. The receptor tyrosine kinase, adhesion-related kinase (Ark) (also known as Axl, UFO, and Tyro7), has been implicated in the migration of GnRH neuronal cells.

Short-term energy restriction reduces resting energy expenditure in patients with HIV lipodystrophy and hypermetabolism.

We have previously shown that resting energy expenditure (REE) is increased in patients with HIV lipodystrophy. This hypermetabolism could be the result of an inadequate storage capacity for lipid fuel secondary to atrophy of the subcutaneous adipose tissue depot. Therefore, energy restriction may be able to alleviate this hypermetabolism.

Pinch-off syndrome in patients with sickle cell disease receiving erythrocytapheresis.

A 6-year-old female with homozygous sickle cell disease had a central venous access device (CVAD) placed to facilitate chronic erythrocytapheresis. Erythrocytapheresis was ineffective due to the rare pinch-off syndrome causing communication between the dual lumen tubing. Awareness of and monitoring for the pinch-off syndrome is indicated in people with sickle cell disease and a CVAD for chronic erythrocytapheresis.

Psychosocial stress increases inflammatory markers and alters cytokine production across pregnancy.

Previous work has shown that psychosocial stress is related to increases in serum levels of pro-inflammatory cytokines late in pregnancy, and a growing body of research suggests that increased inflammatory activity during pregnancy, generally, may have a negative impact on outcome. The present study further addressed these issues by assessing relationships between psychosocial stress, social support and serum cytokines in early, mid, and late pregnancy, and the effects of stress and social support on the production of cytokines by stimulated lymphocytes in late pregnancy. In addition, we examined relationships between stress, support, and serum C-reactive protein (CRP) during pregnancy.

Severe hypertriglyceridemia with a history of treatment failure.

Background A 53-year-old man with a history of hypertension and gout was referred to our clinic for severe hypertriglyceridemia, diagnosed 3 years previously. He was asymptomatic and had no history of abdominal pain, pancreatitis or diabetes, but consumed six cans of beer per night. Over the previous 2 years, he had been treated unsuccessfully with multiple medications; during this period his fasting triglycerides ranged from 5.

Mechanisms of fenretinide-induced apoptosis.

Fenretinide, a synthetic retinoid, has emerged as a promising anticancer agent based on numerous in vitro and animal studies, as well as chemoprevention clinical trials. In vitro observations suggest that the anticancer activity of fenretinide may arise from its ability to induce apoptosis in tumor cells. Diverse signaling molecules including reactive oxygen species, ceramide, and ganglioside GD3 can mediate apoptosis induction by fenretinide in transformed, premalignant, and malignant cells.
