RESUMO

Acute renal failure in the setting of infection with human immunodeficiency virus can be due to various causes including pre-renal causes such as hypotension, sepsis, and nephrotoxic agents; thrombotic microangiopathy; or direct renal parenchymal infections by opportunistic organisms. We present a case of cryptococcal nephritis in a patient with systemic cryptococcosis and discuss the clinical findings as well as the histological, immunofluorescent, and transmission electron microscopy findings in the renal biopsy.

RESUMO

BACKGROUND: In the United States, hemodialysis (HD) is generally performed via a bicarbonate dialysate. It is not known if small amounts of acid used in dialysate to buffer the bicarbonate can meaningfully contribute to overall buffering administered during HD. We aimed to investigate the metabolism of acetate with use of two different acid buffer concentrates and determine if it effects blood bicarbonate concentrations in HD patients. METHODS: The Acid-Base Composition with use of hemoDialysates (ABChD) trial was a Phase IV, prospective, single blind, randomized, cross-over, 2 week investigation of peridialytic dynamics of acetate and bicarbonate associated with use of acid buffer concentrates. Eleven prevalent HD patients participated from November 2014 to February 2015. Patients received two HD treatments, with NaturaLyte® and GranuFlo® acid concentrates containing 4 and 8 mEq/L of acetate, respectively. Dialysate order was chosen in a random fashion. The endpoint was to characterize the dynamics of acetate received and metabolized during hemodialysis, and how it effects overall bicarbonate concentrations in the blood and dialysate. Acetate and bicarbonate concentrations were assessed before, at 8 time points during, and 6 time points after the completion of HD. RESULTS: Data from 20 HD treatments for 11 patients (10 NaturaLyte® and 10 GranuFlo®) was analyzed. Cumulative trajectories of arterialized acetate were unique between NaturaLyte® and GranuFlo® (p = 0.003), yet individual time points demonstrated overlap without remarkable differences. Arterialized and venous blood bicarbonate concentrations were similar at HD initiation, but by 240 min into dialysis, mean arterialized bicarbonate concentrations were 30.2 (SD ± 4.16) mEq/L in GranuFlo® and 28.8 (SD ± 4.26) mEq/L in NaturaLyte®. Regardless of acid buffer concentrate, arterial blood bicarbonate was primarily dictated by the prescribed bicarbonate level. Subjects tolerated HD with both acid buffer concentrates without experiencing any related adverse events. CONCLUSIONS: A small fraction of acetate was delivered to HD patients with use of NaturaLyte® and GranuFlo® acid buffers; the majority of acetate received was observed to be rapidly metabolized and cleared from the circulation. Blood bicarbonate concentrations appear to be determined mainly by the prescribed concentration of bicarbonate. TRIAL REGISTRATION: This trial was registered on ClinicalTrials.gov on 11 Dec 2014 ( NCT02334267 ).

RESUMO

The purpose of this article was to review the empirical literature that investigated trauma and stress among older adults in the criminal justice system. Nineteen journal articles published between 1988 and 2010 were identified and extracted via research databases and included mixed age samples of adjudicated older and younger adults (n = 11) or older adult only samples (n = 8). Findings revealed past and current trauma and stress, consequences and/or correlates, and internal and external coping resources among aging offenders. The implications and future directions for gerontological social work, research, and policy with older adults in the criminal justice system are advanced.

RESUMO

This study examined lifetime trauma and life event stressors among young and older prisoners. A stratified random sample of young (age 18 to 24 years) and older (age 55 and above) male prisoners was drawn from the New Jersey Department of Corrections. Fifty-eight participants completed a modified version of the Trauma and Stressful Life Experiences Screening Inventory during face-to-face interviews. Approximately 40% of young and older adult prisoners reported exposure to violent victimization. Young prisoners were significantly more likely to report witnessing physical assault, whereas older prisoners were significantly more likely to report experiencing a natural disaster, life-threatening illness, or the death of a loved one. Information about the frequency of lifetime trauma and life event stressors can be used to develop or improve trauma-informed services that target age-specific needs, especially for young and older prisoners.
