The World Health Organization's epidemiological data from 2016 revealed that while 57% of the global population aged 15 years or older had abstained from drinking alcohol in the previous year, more than half of the population in the Americas, Europe, and Western Pacific consumed alcohol. The spectrum of alcohol use behavior is broad: low-risk use (sensible and in moderation), at-risk use (e.g.

Existing continuing education programmes to better equip therapists to work with LGBTQ+ clients are often not widely accessible or skills focused, evaluated for effectiveness and inclusive of MHO administrators who can address the organizational climate needed for therapist effectiveness. A virtual, face-to-face, multi-level (administrators and therapists) and multi-strategy (technical assistance, workshop and clinical consultations) LGBTQ+ cultural competence training-the Sexual and Gender Diversity Learning Community (SGDLC)-was tested in a pilot randomized controlled trial.

Excessive alcohol use can disrupt the balance of these microbes (known as dysbiosis), leading to elevated blood endotoxin levels and systemic inflammation. Using QIAGEN Ingenuity Pathway Analysis (IPA) bioinformatics tool, we have confirmed that peripheral endotoxin (lipopolysaccharide) mediates various cytokines to enhance the neuroinflammation signaling pathway.

HIV-Associated Dementia (HAD) is a significant comorbidity that many HIV-patients face. Our study utilized QIAGEN Ingenuity Pathway Analysis (IPA) to identify and analyze molecular profiles and pathways underlying nicotine's impact on HAD pathology. The Qiagen Knowledge Base (QKB) defines HAD as "Dementia associated with acquired immunodeficiency syndrome (disorder).

When an object conditioned stimulus (CS) is paired with a food unconditioned stimulus (US), anticipatory goal-directed action directed at the US location (goal tracking) is accompanied by behavior directed at the object CS (sign tracking). Sign-tracking behavior appears to be compulsive and habit-like and predicts increased vulnerability to the addictive potential of drugs in animal models. A large body of the literature also suggests that environmental enrichment protects against the development of addiction-prone phenotypes.

The new emerging magnetic resonance imaging, computed tomography, and positron emission tomography diagnostic modalities still lack sufficient accuracy. In the last years, a great effort has been made to develop radiotracers able to detect specific altered metabolic pathways or tumor receptor markers.

The HIV-1 transgenic (HIV-1Tg) rat was created with a gag- and pol-deleted HIV-1 viral genome to mimic HIV-infected patients receiving combination anti-retroviral therapy (cART). Docosahexaenoic acid (DHA) is a marine compound that modulates inflammatory responses.
View Article and Find Full Text PDFDespite the ability of current combination anti-retroviral therapy (cART) to limit the progression of HIV-1 to AIDS, HIV-positive individuals continue to experience neuroHIV in the form of HIV-associated neurological disorders (HAND), which can range from subtle to substantial neurocognitive impairment. NeuroHIV may also influence substance use, abuse, and dependence in HIV-positive individuals. Because of the nature of the virus, variables such as mental health co-morbidities make it difficult to study the interaction between HIV and substance abuse in human populations.

We employed a multifaceted behavioral-change intervention to improve communication between families and clinicians in a statewide collaboration of ICUs.
Objectives: Our primary objective was to examine whether the intervention resulted in increased compliance with process measures that targeted clinician-family communication.
Persons infected with HIV-1 often develop neurologic disorders despite receiving highly active anti-retroviral therapy. Although the underlying mechanism is largely undetermined, our previous RNA-seq-based study showed that the expression of many genes was altered in the central nervous system (CNS) of HIV-1 transgenic (HIV-1Tg) rats. Because nicotine, a natural agonist of nicotinic acetylcholine receptors, exhibits a neuroprotective effect, we presently tested the hypothesis that nicotine restores the expression of altered genes in the CNS of HIV-1Tg rats.

Our previous studies revealed significant behavioral differences between HIV-1Tg and F344 control rats in their performance in the Morris water maze and responses to psychostimulants. However, the molecular mechanisms underlying these behavioral differences remain largely unknown.

The mu-opioid receptor (MOR) which mediates the actions of morphine is shown to be up-regulated in the HIV-1 transgenic (HIV-1Tg) rat. In this study, we used the conditioned place preference (CPP) test to investigate if HIV-1Tg rats are more sensitive to the addictive properties of morphine compared to F344 control animals.

Few studies have shown how to draw on a strong safety culture to improve clinical outcomes. A study was conducted to (1) examine the impact of a Safety Attitudes Questionnaire Action Plan (SAQAP) on the 2008 Safety Attitudes Questionnaire (SAQ) and (2) determine the impact of an SAQAP on ICU central line-associated blood stream infections (CLABSIs) and ventilator-associated pneumonia (VAP) rates.

In the present study, we evaluated the effects of a moderate dose of METH on the brains of adolescent versus adult HIV-1 Tg male rats using both behavioral (METH-induced, stereotypic head movement) and physiological (rectal body temperature) parameters. We found that both the acute and behavior-sensitizing effects of METH were greater in HIV-1 Tg rats compared with controls and also in adolescent rats compared with adult animals, regardless of HIV-1 status.

We demonstrate that the developing HIV-1Tg rat, which expresses all of the HIV-1 viral genes except the gag-pol replication genes, maintains lower body weight compared with the F344 control rat. Although HIV-1Tg rats eat and drink less than the control animals, they are not anorexic and show no evidence of anhedonia.

With the advent of highly active antiretroviral therapy (HAART), these deficits have become milder, but more prevalent as the population of HIV-positive individuals ages. Mild impairment in cognition has also been identified in asymptomatic HIV-1 patients.

A factor analysis yielded a multidimensional structure with attitudes toward animal research, nonresearch, environment, and evolution as factors. Beginning psychology students had a more negative attitude toward animal research than did psychology majors; however, psychology majors displayed a more positive attitude toward the environment and toward animal rights issues not involving animal research.
