Drug use prevention

Srinivas R Nalamachu, Binit Shah
Deaths from opioid overdoses have increased dramatically over the past few years. Given that immediate-release (IR) opioids account for most of the US market share, and that abusers generally prefer IR opioids over extended-release (ER) opioids, it is not surprising that rates of abuse are higher for IR than ER opioids. IR opioids are widely prescribed, often without consideration for risks of abuse, misuse, and diversion. Prescription opioid abuse and misuse often begins through oral administration and progresses into non-oral routes (e...

The purpose of this study was to determine whether blocking of G protein βγ (Gβγ) signaling halts heart failure (HF) progression by macrophage phenotype manipulation. Cardiac Gβγ signaling plays a crucial role in HF pathogenesis. Previous data suggested that inhibiting Gβγ signaling reprograms T helper cell 1 (Th1) and Th2 cytokines, suggesting that Gβγ might be a useful drug target for treating HF. We investigated the efficacy of a small molecule Gβγ inhibitor, gallein, in a clinically relevant, experimental autoimmune myocarditis (EAM) model of HF as well as in human macrophage phenotypes in vitro...

OBJECTIVE: This study analyzed the appropriateness of drug therapies prescribed for a particular category of patients: the seafarers. We investigated an important problem of this area: the off-label use of drugs, which resulted to be a consequence of major shortcomings in the on-board pharmacies of ships. The off-label use of drugs is allowed, but can lead to some not negligible ethical and health problems, compromising the quality of provided healthcare. MATERIALS AND METHODS: The analysis was performed on electronic health records of patients onboard ships without physicians, and assisted by the CIRM from 2011 to 2015...

PURPOSE OF REVIEW: This review discusses the role and mechanisms by which facilitating cells promote stem cell engraftment and induce tolerance in HLA-disparate kidney transplant recipients. RECENT FINDING: Facilitating cells in both mice and human are heterogeneous, consisting of several subpopulations. They have been shown to enhance stem cell engraftment in allogeneic recipients. They also increase hematopoietic stem cells (HSC) clonogenicity, enhance migration and homing of stem cells via secretion of cytokines/chemokines/growth factors, prevent apoptosis of stem cells and induce regulatory cells...

BACKGROUND: Stroke is an important cause of death and disability worldwide. Since high blood pressure is an important risk factor for stroke and stroke recurrence, drugs that lower blood pressure might play an important role in secondary stroke prevention. OBJECTIVES: To investigate whether blood pressure-lowering drugs (BPLDs) started at least 48 hours after the index event are effective for the prevention of recurrent stroke, major vascular events, and dementia in people with stroke or transient ischaemic attack (TIA)...

Breast cancer is the most devastating disease among females globally. Conventional chemotherapeutic regimen relies on the use of highly cytotoxic drugs as monotherapy and combination therapy leading to severe side effects to the patients as collateral damage. Moreover, combining hydrophobic and hydrophilic drugs create erratic biodistribution and suboptimal medicinal outcome. Hence, packaging multiple drugs of diverse mechanisms of action and biodistribution for safe delivery into tumor tissues with optimal dosages is indispensable for next-generation breast cancer therapy...

Background: Previous literature suggests that prevalence of cannabis use in the early phase of psychosis is high, and that early psychosis patients are at high-risk for violent behavior. However, the link between cannabis use and violent behavior in early psychosis patients is unclear. We carried out a study on a sample of early psychosis patients, in order to explore the impact of cannabis use on the risk of violent behavior (VB), while taking into account (1) potential confounding factors and, (2) interactions with other dynamic risk factors of VB...

Background: Alzheimer's disease (AD) is a devastating neurodegenerative disorder that lacks any disease-modifying drug for the prevention and treatment. Edaravone (EDR), an approved free radical scavenger, has proven to have potential against AD by targeting multiple key pathologies including amyloid-beta (Aβ), tau phosphorylation, oxidative stress, and neuroinflammation. To enable its oral use, novel edaravone formulation (NEF) was previously developed. The aim of the present investigation was to evaluate safety and efficacy of NEF by using in vitro/in vivo disease model...

Female adolescents from socioeconomically underserved communities in Cape Town, South Africa, who have dropped out of school, use substances, and engage in risky sex behaviour are at risk of HIV. Tailored gender-focused HIV behavioural interventions for this key population are needed to mitigate these risk factors. A pilot trial of a woman-focused risk-reduction intervention for adolescents was conducted (N = 100), with a one-month follow-up appointment. Participants in the intervention group attended two group workshops...

Medicinal plants and herbal extracts from traditional Chinese medicine are used increasingly commonly worldwide for their benefits to health and quality of life as dietary supplements or as ingredients in functional foods. Among them, Salvia miltiorrhiza Bunge (a natural strong remedy for the treatment of a variety of conditions) is traditionally used for centuries in Asian countries as antioxidant, anticancer, and anti-inflammatory agent. In this context, several evidences support the hypothesis that some tanshinones (in particular tanshinone IIA and cryptotanshinone) extracted from the roots (Danshen) of Salvia miltiorrhiza exert neuroprotective and analgesic activities...

Immune recognition of tumor-expressed antigens by cytotoxic CD8+ T cells is the foundation of adoptive T cell therapy (ACT) and has been shown to elicit significant tumor regression. However, therapy-induced selective pressure can sculpt the antigenicity of tumors, resulting in outgrowth of variants that lose the target antigen. We demonstrate that tumor relapse from ACT and subsequent oncolytic viral vaccination can be prevented using class I HDACi, MS-275. Drug delivery subverted the phenotype of tumor-infiltrating CD11b+ Ly6Chi Ly6G- myeloid cells, favoring NOS2/ROS secretion and pro-inflammatory genes characteristic of M1 polarization...

The modulation of immune checkpoint receptors has been one of the most successful, exciting and explored approaches for cancer immunotherapy. Currently several immune checkpoint modulators, mainly monoclonal antibodies, are showing remarkable results. However, the failure to show a response in most patients and the induction of severe immune-related adverse effects are the major drawbacks. Novel approaches concerning the development of immune modulatory small molecules have emerged as an alternative. Nevertheless, the lack of structural information about immune checkpoint receptors has hindered the rational design of those small-molecule modulators, by preventing the use of methodologies such as computer-aided drug design...

Repurposing is the discovery - whether or not by accident - of a new use for an existing product, for example, a new indication for a drug. In the past, several psychotropic drugs have received their place in the treatment arsenal via this route. Both in psychiatry and addiction medicine, there is an important need for new treatments with new working mechanisms. Potential new uses in both psychiatry and addiction medicine of several drugs that have already been registered for other indications are currently under study...

BACKGROUND: The American Heart Association concluded that waist circumference was a better predictor of blood pressure risk than BMI in Asians. However, data are inconsistent and information in Chinese, the largest global population group, is limited. METHODS: Data was obtained from the Chinese National Stroke Prevention Project Survey of a nationally representative sample of middle-aged and older Chinese adults. A total of 135 825 individuals not taking any antihypertensive drugs were included in this study...

Individuals with multiple suicide attempts have a greater risk for eventual suicide death. We investigated clinical differences in participants with single versus multiple suicide attempts. Individuals with multiple attempts were more likely to have severe depressive symptoms, drug use disorder, and a higher wish to die. Borderline personality disorder traits and drug use disorder were significant predictors of multiple attempts when adjusting for other psychiatric disorders. Participants with multiple attempts sustained higher suicidal ideation-worst and wish to die/wish to live-worst scores during the 3-month assessment period...

Malaria remains one of the most lethal infectious diseases worldwide, and the most severe form is caused by Plasmodium falciparum. In recent decades, the major challenge to treatment of this disease has been the ability of the protozoan parasite to develop resistance to the drugs that are currently in use. Among P. falciparum enzymes, P. falciparum dihydroorotate dehydrogenase has been identified as an important target in drug discovery. Interference with the activity of this enzyme inhibits de novo pyrimidine biosynthesis and consequently prevents malarial infection...
