Differential contribution of chronic binge alcohol and antiretroviral therapy to metabolic dysregulation in SIV-infected male macaques.

The incidence of alcohol use disorder (AUD) is higher among people living with HIV (PLWH). The advent and continued development of antiretroviral therapy (ART) has significantly reduced mortality, shifting the course of HIV infection to a chronic illness. However, this is associated with an increased incidence of comorbid conditions, including type 2 diabetes mellitus, insulin resistance, and cardiovascular complications.

Repeated Binge-Like Alcohol Intoxication: Depot-Specific Adipose Tissue Immuno-Metabolic Dysregulation.

Repeated binge-like alcohol intoxication (RBAI) induces whole-body insulin resistance, which is predicted to increase the risk for metabolic syndrome and type 2 diabetes. Previously, we showed that acute alcohol intoxication increases mesenteric lymphatic permeability, perilymphatic adipose tissue (PLAT) inflammation, and circulating lipopolysaccharide levels in rats. We hypothesize that mesenteric lymphatic hyperpermeability, adipose tissue inflammation and associated dysregulated adipokine expression, and insulin signaling are central mechanisms underlying whole-body metabolic dysregulation resulting from RBAI.

Chronic binge alcohol administration impairs glucose-insulin dynamics and decreases adiponectin in asymptomatic simian immunodeficiency virus-infected macaques.

Alcohol use disorders (AUDs) frequently exist among persons living with HIV/AIDS. Chronic alcohol consumption, HIV infection, and antiretroviral therapy (ART) are independently associated with impairments in glucose-insulin dynamics. Previous studies from our laboratory have shown that chronic binge alcohol (CBA) administration decreases body mass index, attenuates weight gain, and accentuates skeletal muscle wasting at end-stage disease in non-ART-treated simian immunodeficiency virus (SIV)-infected male rhesus macaques.

Alcohol's Burden on Immunity Following Burn, Hemorrhagic Shock, or Traumatic Brain Injury.

Alcohol consumption contributes to increased incidence and severity of traumatic injury. Compared with patients who do not consume alcohol, alcohol-consuming patients have higher rates of long-term morbidity and mortality during recovery from injury. This can be attributed in part to an impaired immune response in individuals who consume alcohol.

Direct evidence for intrarenal chymase-dependent angiotensin II formation on the diabetic renal microvasculature.

Our previous work supports a major role for angiotensin-converting enzyme (ACE)-independent intrarenal angiotensin (ANG) II formation on microvascular function in type 2 diabetes mellitus. We tested the hypothesis that there is a switch from renal vascular ACE-dependent to chymase-dependent ANGII formation in diabetes mellitus. The in vitro juxtamedullary afferent arteriole (AA) contractile responses to the intrarenal conversion of the ACE-specific, chymase-resistant ANGI peptide ([Pro(10)]ANGI) to ANGII were significantly reduced in kidneys of diabetic (db/db) compared with control (db/m) mice.

Comparison of the trivalent live attenuated vs. inactivated influenza vaccines among U.S. military service members.

Limited effectiveness data are available comparing live attenuated influenza vaccine (LAIV) to inactivated influenza vaccine (TIV) among adults. To compare the incidence of influenza-like illness following immunization of adults with LAIV vs. TIV, we conducted a retrospective cohort analysis of active component U.

Stability of oseltamivir in various extemporaneous liquid preparations.

The purpose of this study was to determine the stability of oseltamivir, the active ingredient in Tamiflu, in contemporaneously compounded suspensions for a period of not less than 90 days. The suspension vehicles provided for the study were chosen because of ease of preparation, commercial availability, and palatability. Stability of the active ingredient was demonstrated for suspensions prepared in PCCA-Plus, PCCA Acacia, and 1% methylcellulose and was independent of storage temperature (tested temperatures were 2 deg C to 8 deg C and 25 deg C).

Pandemics, avian influenza A (H5N1), and a strategy for pharmacists.

Epidemics of influenza occur annually and account for more morbidity in the developed world than all other respiratory diseases combined. On average, 36,000 Americans die from influenza or its complications each year. Pandemics occur when influenza viruses undergo either antigenic drift or antigenic shift that results in a new viral strain that infects humans, when they are capable of sustained transmission from person-to-person, and when they are introduced in populations with little or no preexisting immunity.

Intravenous immunoglobulin therapy results in post-infusional hyperproteinemia, increased serum viscosity, and pseudohyponatremia.

Intravenous immunoglobulin (IVIG) therapy is associated with rare reports of thromboembolic events and severe hyponatremia. We hypothesized that IVIG therapy may result in hyperproteinemia, increased serum viscosity, and pseudohyponatremia. We conducted a prospective observational study to evaluate the incidence of hyperproteinemia occurring after IVIG therapy and its relationship to serum sodium, viscosity, osmolality, and the serum osmolar gap.

Depressive Disorder in Older Medical Inpatients on General Medicine and Cardiology Services at a University Teaching Hospital.

The authors examined the prevalence, characteristics, and correlates of depressive disorder among medical inpatients age 60 or over at a private teaching hospital. Seventy-six of 129 patients admitted to the general medicine and cardiology services at Duke University Hospital were screened for depressive disorder using DSM-III-R criteria. Depressive disorders were diagnosed in 34.
