Coping with Community Violence: Perspectives of African American Young Adult Men and Hispanic/Latino Young Adult Men.

Further study is needed regarding the intersection of community violence exposure, coping strategies, and health behaviors among young adult African American men and Hispanic/Latino men. This study did so in Lake County, Indiana, which contains multiple areas with disproportionate prevalence of violence relative to population size. Approximately 22 miles from Chicago, Lake County includes noteworthy mid-sized cities such as Gary, Hammond, and East Chicago.

Predicting the role of coping factors on pandemic-related anxiety.

The year 2020 saw the emergence of a worldwide pandemic caused by the novel coronavirus COVID-19. Measures against further spread of the virus were taken nearly everywhere in the world. Many countries also imposed social distancing rules and lockdowns on their population.

Reflected near-infrared light versus bite-wing radiography for the detection of proximal caries: A multicenter prospective clinical study conducted in private practices.

Objectives: The aim of the present prospective multicenter clinical study was to compare the detection of proximal caries with near-infrared light reflection (NILR) versus bitewing radiography (BWR).

Materials And Methods: Intraoral scans were performed on 100 patients in five dental clinics using an intraoral scanner (iTero Element 5D, Align Technology, Tempe, AZ, USA) that includes a near-infrared light source (850 nm) and sensor. Reflected near-infrared light images of posterior teeth were used by the individual dentists to detect proximal caries and the results were compared to the BWRs.

Increases in CSF dopamine in HIV patients are due to the dopamine transporter 10/10-repeat allele which is more frequent in HIV-infected individuals.

Dysfunction of dopaminergic neurotransmission has been implicated in HIV infection. We showed previously increased dopamine (DA) levels in CSF of therapy-naïve HIV patients and an inverse correlation between CSF DA and CD4 counts in the periphery, suggesting adverse effects of high levels of DA on HIV infection. In the current study including a total of 167 HIV-positive and negative donors from Germany and South Africa (SA), we investigated the mechanistic background for the increase of CSF DA in HIV individuals.

[Neuro-AIDS in the cART era].

After the introduction of antiretroviral combination therapy for the treatment of HIV infection in 1996 (highly active antiretroviral therapy = HAART, nowadays called combination antiretroviral therapy = cART), a steady decline in infection associated complications had been expected, especially with respect to central and peripheral nervous system manifestations. Until the beginning of the new millenium this hope came in fact true, but since then there has been a slow, but constant rise in the prevalence, and later on also in the incidence of directly virus-associated neurological complications in HIV infected patients. HIV-associated diseases that neurologists might see in their routine work include HIV-associated dementia (HAD) and its precursor stages, HIV-associated myelopathy, HIV-associated polyneuropathies and myopathies as well as the opportunistic brain infections and immune reconstitution phenomena (IRIS).

Cytokine levels in CSF and neuropsychological performance in HIV patients.

HIV-associated dementia and its precursors are frequently observed complications of HIV infection, even in the presence of combination antiretroviral treatment (cART). The development, surveillance and treatment of this condition are still not completely understood. Cytokines, as immunological transmitters, may be one key to gaining a deeper understanding of the disease.

Increased dopaminergic neurotransmission in therapy-naïve asymptomatic HIV patients is not associated with adaptive changes at the dopaminergic synapses.

Central dopaminergic (DA) systems are affected during human immunodeficiency virus (HIV) infection. So far, it is believed that they degenerate with progression of HIV disease because deterioration of DA systems is evident in advanced stages of infection. In this manuscript we found that (a) DA levels are increased and DA turnover is decreased in CSF of therapy-naïve HIV patients in asymptomatic infection, (b) DA increase does not modulate the availability of DA transporters and D2-receptors, (c) DA correlates inversely with CD4+ numbers in blood.

Measurement of soluble inflammatory mediators in cerebrospinal fluid of human immunodeficiency virus-positive patients at distinct stages of infection by solid-phase protein array.

The objective of this study was to evaluate immune cytokine expression in cerebrospinal fluid (CSF) of patients with human immunodeficiency virus-1 (HIV-1)-associated dementia (HAD) using a novel cytokine array assay. HIV-1 induces a condition resembling classical subcortical dementia, known as HAD. The immune mechanisms contributing to HAD have not been elucidated.

[Neurological complications of HIV infection].

After the introduction of highly active antiretroviral therapy (HAART) in the treatment of HIV (human immunodeficiency virus) infection in 1996, neurological complications of this worldwide infectious disease declined in incidence and prevalence. During the following years however, prevalence and finally also incidence, especially of HIV-associated dementia and its precursor stages, rose again. Nowadays neurologists are confronted with HIV-associated neurocognitive disorders, depression, polyneuropathies and muscle disease, opportunistic brain infections (toxoplasmosis, cryptococcosis, cytomegalovirus infection, progressive multifocal leucoencephalopathy), rising rates of neurosyphilis, and the so-called immune reconstitution syndrome which therefore are topics of this review.

Cidofovir in combination with HAART and survival in AIDS-associated progressive multifocal leukoencephalopathy.

Progressive multifocal leukoencephalopathy is a demyelinating disease with a high mortality caused by the JC virus and occurs in about 5% of HIV-infected patients. Highly active anti-retroviral therapy (HAART) has a proven efficacy in prolonging the survival of patients with AIDS-associated PML, but there are differing opinions about adding cidofovir to the treatment of PML. To investigate the benefit of HAART combined with cidofovir, we retrospectively analysed the survival of 33 patients with AIDS-associated PML proven by PCR in CSF, biopsy or at autopsy.

Viral load determines the B-cell response in the cerebrospinal fluid during human immunodeficiency virus infection.

Objective: Human immunodeficiency virus (HIV) infection of the central nervous system (CNS) is frequently associated with intrathecal immunoglobulin synthesis and cerebrospinal fluid (CSF) pleocytosis, but little is known about the B-cell response in the CSF of these patients. In this study, we investigated the relation between virus load and the frequency and phenotype of B cells in the CSF of HIV-infected patients.

Methods: The distribution of T cells, B cells, short-lived plasmablasts, and long-lived plasma cells was analyzed by flow cytometry in CSF and peripheral blood of 33 patients with HIV infection compared with 12 patients with noninfectious CNS diseases.

Intrathecal viral replication and cerebral deficits in different stages of human immunodeficiency virus disease.

The objectives of this study is to clarify whether there are phases critical for the infection of the central nervous system (CNS) as defined by active viral replication in the cerebrospinal fluid (CSF) in human immunodeficiency virus (HIV) infection. One hundred and nine HIV-1-positive homo- and bisexual patients in early and late disease stages with or without highly active antiretroviral therapy (HAART) were included in the cross-sectional, diagnostic (phase I) multicenter study. No patients had any overt neurological deficits; all underwent venous and lumbar puncture as well as neuropsychological testing.

Neuropsychiatric side effects of efavirenz therapy.

The non-nucleoside analogue inhibitor of the reverse transcriptase, efavirenz (EFV), has become commonly used in highly active antiretroviral combination therapy in the treatment of HIV infection. Although being effective in suppressing plasma viral load, neuropsychiatric side effects have been reported in individuals treated with EFV. There are early complications, such as acute psychosis resembling reactions to LSD intake, as well as nightmares occurring for several days up to 4 weeks after the start of therapy.

CD8 T-cell subsets and viral load in the cerebrospinal fluid of therapy-naive HIV-infected individuals.

Central nervous system involvement is common in HIV infection. We determined the relationship between T-cell subsets and viral load in the cerebrospinal fluid (CSF) of therapy-naive, asymptomatic HIV-infected individuals. A shift from naive to effector-memory CD8 T cells was observed in the CSF of HIV-infected individuals compared with controls.

[Neurological manifestations of the HIV infection].

As a result of improved therapeutic possibilities with highly active antiretroviral therapy (HAART), an increasing prevalence of neurological complications of the HIV infection is observed. In particular, some authors now also describe a "morphogenesis" of the HIV-1-related encephalopathy. The current state of knowledge should be taken into account in the diagnostics and therapy of HIV-1-related encephalopathy, depression, progressive multifocal leukencephalopathy and polyneuropathy.
