What Factors Are Associated With Implant Failure?

Purpose: Recognition of patient-specific risk factors should reduce implant failure. The purpose of this study was to identify risk factors associated with implant failure and to determine if these factors differ over time after implant placement.

Methods: The investigators implemented a retrospective case-controlled study and enrolled a sample composed of patients who had 1 or more implants removed from December 1, 2007 to February 29, 2020.

Chronic Binge Alcohol-Associated Differential Brain Region Modulation of Growth Factor Signaling Pathways and Neuroinflammation in Simian Immunodeficiency Virus-Infected Male Macaques.

Aims: Microarray analysis of hippocampal tissue from chronic binge alcohol (CBA)-administered, simian immunodeficiency virus (SIV)-infected male macaques identified altered immune response and neurogenesis as potential mechanisms underlying cognitive deficits in macaques. This study investigated the differential brain region associations between markers of neuroinflammation and growth factor signaling with microtubule-associated protein 2 (MAP2) expression.

Methods: Adult male rhesus macaques were administered CBA (13-14 g EtOH/kg/week, n = 8) or sucrose (SUC, n = 7) beginning 3 months prior to SIV infection and continued until animals reached end-stage disease criteria (3-24 months post infection).

Simian Immunodeficiency Virus Infection Increases Blood Ethanol Concentration Duration After Both Acute and Chronic Administration.

Alcohol use disorder (AUD) is a frequent comorbidity among people living with HIV/AIDS (PLWHA). Alcohol consumption is a significant predictor of nonadherence to antiretroviral therapy (ART), as well as worsening immunological and virological indicators among PLWHA. Clinical studies indicate that higher viral loads increase sensitivity to alcohol in PLWHA.

An open-label study of olanzapine in children and adolescents with schizophrenia.

The purpose of this open-label study was to evaluate the use of olanzapine in the treatment of children and adolescents with schizophrenia. Sixteen children who were 8-17 years of age and met DSM-IV criteria for schizophrenia were admitted into a 10-week, open-label, optimizing dose study of olanzapine. The Brief Psychiatric Rating Scale (BPRS), the Positive and Negative Syndrome Scale (PANSS), and the Clinical Global Impression (CGI)-Severity/Improvement scales were used to assess improvement during the study.

Root surface removal and resultant surface texture with diamond-coated ultrasonic inserts: an in vitro and SEM study.

Background: A new diamond-coated ultrasonic insert has been developed for scaling and root planing, and it was evaluated in vitro for the amount of root surface removed and the roughness of the residual root surface as a result of instrumentation.

Methods: 48 extracted single-rooted human teeth were ground flat on one root surface and mounted (flat side up) in PVC rings of standard height and diameter with improved dental stone. Each tooth surface was treated with either a plain ultrasonic insert (PI), an ultrasonic insert with a fine grit diamond coating (DI) or sharp Gracey curettes (HI).

Similar age-specific PSA, complexed PSA, and percent cPSA levels among African-American and white men of southern Louisiana. Prostate-specific antigen.

Objectives: To determine the mean and median complexed prostate-specific antigen (cPSA) levels in a predominantly African-American population and to explore whether differences in cPSA exist between the races. Differences in total PSA (tPSA) levels between age-matched African-American and white men have been reported by several groups. Age-specific cPSA levels, however, have not been thoroughly evaluated and reported among African-American populations.
