Drug use prevention

Mance E Buttram, Steven P Kurtz
Background: Limited information suggests that men who have sex with men (MSM) are informally obtaining antiretroviral medication (ARVs) and using them for HIV pre-exposure prophylaxis (PrEP). Methods: Data are drawn from an on-going study examining the use of non-prescribed ARVs for PrEP. To date, 24 qualitative interviews have been conducted with HIV-negative, substance-using MSM living in Miami, Florida, USA. Data are presented from two participants who reported HIV seroconversion while using non-prescribed ARVs for PrEP...

BACKGROUND: We have previously reported on a novel organ-specific immunomodifying therapy that provides protection from early allograft rejection in the absence of systemic immunosuppressive drugs. This novel therapy is a nano-barrier membrane called ImmunoCloak, consisting of a matrix of laminin, proteoglycans, fibronectin and collagens. The membrane "immunocloaks" the luminal surfaces within the renal vasculature by covering the point of contact between donor vascular endothelial cells and the recipient's immune cells; without adversely affecting renal function...

PURPOSE OF REVIEW: Tocolytic agents have been used for over 60 years in the fight against preterm labor, which ultimately can lead to preterm birth. Currently, clinicians can choose from a variety of drug classes to achieve the primary goal of delaying delivery by 48 h, thereby allowing time for administration of corticosteroids for fetal lung maturity, and if appropriate, starting magnesium sulfate for fetal neuroprotection. However, there are currently no known therapies to maintain the tocolytic effect beyond those initial 48 h...

OBJECTIVE: A recent HIV outbreak in a rural network of persons who inject drugs (PWID) underscored the intersection of the expanding epidemics of opioid abuse, unsterile injection drug use (IDU), and associated increases in hepatitis C virus (HCV) infections. We sought to identify US communities potentially vulnerable to rapid spread of HIV, if introduced, and new or continuing high rates of HCV infections among PWID. DESIGN: We conducted a multistep analysis to identify indicator variables highly associated with IDU...

Our qualitative study examined how stresses of daily life affected substance use and perceived risk among Black and Hispanic adolescents. We conducted 11 focus groups with students aged 13-25 in public and alternative schools in Providence, Rhode Island, using Bourdieu's Social Practice theoretical approach to guide questioning and data analysis. Despite participants' frequent marijuana use, they perceived the emphasis society places on substance use as misguided, obfuscating the persistence of more critical problems such as stress and reduced opportunity resulting from neighborhood violence, poor schools, financial difficulties, and home troubles...

HIV-1 incidence among youth, especially men who have sex with men (MSM), is increasing in the US. We aimed to better understand the patterns of adolescent HIV-1 acquisition, in order to help guide future prevention interventions. We conducted a study combining epidemiologic and HIV-1 pol sequence data from a retrospective cohort of HIV-infected adults and adolescents in Seattle, WA between 2000 and 2013. Adolescents were defined as 13-24 years of age at the time of first HIV-1 care. Maximum-likelihood phylogenetic trees were reconstructed to identify putative viral transmission clusters of two or more individuals, followed by multivariable regression tests of associations between clustering and demographic and clinical parameters...

Success rates for treatment of extensively drug resistant tuberculosis (XDR-TB) are low due to limited treatment options, delayed diagnosis and inadequate health care infrastructure. Areas covered: This review analyses existing programmes of prevention, diagnosis and treatment of XDR-TB. Improved diagnostic procedures and rapid molecular tests help to select appropriate drugs and dosages. Drugs dosages can be further tailored to the specific conditions of the patient based on quantitative susceptibility testing of the M...

Preclinical Research Approximately 2,500 years ago, Hippocrates used the word herpes as a medical term to describe lesions that appeared to creep or crawl on the skin, advocating heat as a possible treatment. During the last 50 years, pharmaceutical research has made great strides, and therapeutic options have expanded to include small molecule antiviral agents, protease inhibitors, preventive vaccines for a handful of the papillomaviruses, and even cures for hepatitis C virus infections. However, effective treatments for persistent and recurrent viral infections, particularly the highly prevalent herpesviruses, continue to represent a significant unmet medical need, affecting the majority of the world's population...

The human gastrointestinal tract is the primary site of colonization of multidrug resistant pathogens and the major source of life-threatening complications in critically ill and immunocompromised patients. Eradication measures using antibiotics carry further risk of antibiotic resistance. Furthermore, antibiotic treatment can adversely shift the intestinal microbiome toward domination by resistant pathogens. Therefore, approaches directed to prevent replacement of health promoting microbiota with resistant pathogens should be developed...

BACKGROUND: Cisplatin (Cis) is one of the most commonly used antineoplastic drugs. It is used as chemotherapy for many solid organ malignancies such as brain, neck, male and female urogenital, vesical and pulmonary cancers. Infliximab blocks tumor necrosis factor alpha (TNF-α). Several studies have reported that infliximab ameliorates cell damage by reducing cytokine levels. AIMS: We aimed to investigate whether infliximab has a preventive effect against cisplatin-induced hepatotoxicity and whether it has a synergistic effect when combined with Cis...

Medications such as ß-blockers are currently the primary treatment for patients with hereditary arrhythmia syndromes such as long QT syndrome (LQTS) and catecholaminergic polymorphic ventricular tachycardia (CPVT). However, these drugs are ineffective in some patients, and the other treatment option, that is implantable cardioverter defibrillator (ICD) implantation, is associated with significant complications in young and active patients. Left cardiac sympathetic denervation (LCSD) may reduce the wide gap between life-long ß-blocker medication and ICD implantation...

BACKGROUND: Light and/or intermittent smokers have been the fastest growing segment of cigarette smokers in the U.S. over the past two decades. Defining their behavioral characteristics is a critical public health priority. MATERIALS AND METHODS: Our sample included 78,229 U.S. adults from three pooled contemporary population-based surveys: the 2012 NHIS, 2012 NSDUH, and 2011-2012 NHANES. We classified current smokers into four categories (light and intermittent [LITS], light-daily, heavier-intermittent and heavier-daily) and assessed smoking behaviors, illicit drug use, and mental health indicators using weighted analyses...

Cytomegalovirus (CMV) infection is a significant complication in hematopoietic cell transplantation (HCT) recipients. Four antiviral drugs are used for preventing or treating CMV: ganciclovir, valganciclovir, foscarnet, and cidofovir. With prolonged and repeated use of these drugs, CMV can become resistant to standard therapy, resulting in increased morbidity and mortality, especially in HCT recipients. Antiviral drug resistance should be suspected when CMV viremia (DNAemia or antigenemia) fails to improve or continue to increase after 2 weeks of appropriately dosed and delivered antiviral therapy...

Misfolding and aggregation of Cu, Zn superoxide dismutase (SOD1) is implicated in the etiology amyotrophic lateral sclerosis (ALS). The use of small molecules may stabilize the spatial structure of SOD1 dimer, thus preventing its dissociation and aggregation. In this study, "native" mass spectrometry (MS) was used to study the non-covalent interactions between SOD1 and flavonoid compounds. MS experiments were performed on a quadruple time-of-flight (Q-ToF) mass spectrometer with an electrospray ionization (ESI) source and T-wave ion mobility...

The methylfolate trap, a metabolic blockage associated with anemia, neural tube defects, Alzheimer's dementia, cardiovascular diseases, and cancer, was discovered in the 1960s, linking the metabolism of folate, vitamin B12, methionine and homocysteine. However, the existence or physiological significance of this phenomenon has been unknown in bacteria, which synthesize folate de novo. Here we identify the methylfolate trap as a novel determinant of the bacterial intrinsic death by sulfonamides, antibiotics that block de novo folate synthesis...

Statins may be causally associated with a decreased risk of venous thrombosis. If so, this could be a substantive breakthrough since statins do not increase the risk of bleeding and could therefore be used as a safer antithrombotic drug. However, scepticism exists on the observed reduction of venous thrombosis by statins, as it may have been confounded by healthy user effects or other biases. Areas covered: The main focus of this review will be the biases that may have arisen in clinical studies that investigated the relationship between statin use and risk of venous thrombosis...
