INTRODUCTION: While marijuana has been legal for medical purposes in California since 1996, little is known about the health histories of young adult medical marijuana patients who are a significant proportion of medical marijuana patients. We examined whether young adult medical marijuana patients reported health conditions and motivations for use that were consistent with medical use of marijuana in California. METHODS: Young adults (N = 366) aged 18 to 26 years were sampled in Los Angeles in 2014-2015 and segmented into medical marijuana 'patients' (n = 210), marijuana users with a current recommendation, and non-patient users or 'non-patients' (n = 156), marijuana users who never had a medical marijuana recommendation...

Metallic Ni1-x V x alloys exhibit a ferromagnetic to paramagnetic disordered quantum phase transition in bulk. Such a phase transition is accompanied by a quantum Griffiths phase (QGP), featuring fractional power-law temperature dependences of physical variables, like magnetic susceptibility and specific heat, at low temperatures. As nanoparticles (NP's) usually exhibit properties significantly different from their bulk counterparts, it is intriguing to explore the occurrence of quantum Griffiths phase in Ni1-x V x nanoalloys...

OBJECTIVE: The importation of Neisseria gonorrhoeae (NG) strains from overseas is believed to be the main source of antimicrobial resistance in Australia. With recent sporadic cases of ceftriaxone-resistant gonorrhoea reported in Australia and elsewhere, we sought to model the potential for imported NG strains to persist in the men who have sex with men (MSM) population in Australia. METHODS: We developed an individual-based model to simulate the transmission of NG in a population of urban MSM, and used this model to investigate factors contributing to the probability that an imported NG strain will persist...

BACKGROUND: The National Health Insurance Law in Israel ensures basic health basket eligibility for all its citizens. A supplemental health insurance plan (SHIP) is offered for an additional fee. Over the years, the percentage of supplemental insurance's holders has risen considerably, ranking among the highest in OECD countries. The assumption that consumers implement an informed rational choice based on relevant information is doubtful. Are consumers sufficiently well informed to make market processes work well? OBJECTIVES: To examine perspectives, preferences and knowledge of Israelis in relation to SHIP...

OBJECTIVES: To compare the risk of fatal injury across helmet types among collision-involved motorcyclists. METHODS: We used data from a cohort of motorcyclists involved in police-reported traffic collisions. Eighty-four law enforcement agencies in California collected detailed information on helmet and rider characteristics during collision investigations in June 2012 through July 2013. Multiply-adjusted risk ratios were estimated with log-binomial regression. RESULTS: The adjusted fatal injury risk ratio for novelty helmets was 1...

A simple, accurate and fast spectrophotometric method for the quantitative determination of melatonin (ML) drug in its pure and pharmaceutical forms was developed based on the formation of its charge transfer complex with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) as an electron acceptor. The different conditions for this method were optimized accurately. The Lambert-Beer's law was found to be valid over the concentration range of 4-100μgmL(-1) ML. The solid form of the CT complex was structurally characterized by means of different spectral methods...

A modest, but growing, body of case law is developing around the (non-)treatment of patients in the minimally conscious state. We sought to explore the approaches that the courts take to these decisions. Using the results of a qualitative analysis, we identify five key features of the rulings to date. First, the judges appear keen to frame the cases in such a way that these are rightly matters for judicial determination. Secondly, the judges appraise the types and forms of expertise that enter the courtroom, seeming to prefer the 'objective' and 'scientific', and particularly the views of the doctors...

OBJECTIVES: Pazopanib received US Food and Drug Administration approval in 2009 for advanced renal cell carcinoma. During clinical development, liver chemistry abnormalities and adverse hepatic events were observed, leading to a boxed warning for hepatotoxicity and detailed label prescriber guidelines for liver monitoring. As part of postapproval regulatory commitments, a cohort study was conducted to assess prescriber compliance with liver monitoring guidelines. METHODS: Over a 4-year period, a distributed network approach was used across 3 databases: US Veterans Affairs Healthcare System, a US outpatient oncology community practice database, and the Dutch PHARMO Database Network...

We investigate capillary wave turbulence at scales larger than the forcing one. At such scales, our measurements show that the surface waves dynamics is the one of a thermal equilibrium state in which the effective temperature is related to the injected power. We characterize this evolution with a scaling law and report the statistical properties of the large-scale surface elevation depending on this effective temperature.

I Rouse, S Willitsch
An ion in a radio frequency ion trap interacting with a buffer gas of ultracold neutral atoms is a driven dynamical system which has been found to develop a nonthermal energy distribution with a power law tail. The exact analytical form of this distribution is unknown, but has often been represented empirically by q-exponential (Tsallis) functions. Based on the concepts of superstatistics, we introduce a framework for the statistical mechanics of an ion trapped in an rf field subject to collisions with a buffer gas...

A distinct thermal Hall signal is observed in a quantum spin liquid candidate Ba_{3}CuSb_{2}O_{9}. The transverse thermal conductivity shows a power-law temperature dependence below 50 K, where a spin gap opens. We suggest that because of the very low longitudinal thermal conductivity and the thermal Hall signals, a phonon Hall effect is induced by strong phonon scattering of orphan Cu^{2+} spins formed in the random domains of the Cu^{2+}-Sb^{5+} dumbbells in Ba_{3}CuSb_{2}O_{9}.

Exploiting the enabling power of the Lanczos method in momentum space, we determine accurately the quasiparticle and scaling properties of disordered three-dimensional Dirac semimetals surrounding the quantum critical point separating the semimetal and diffusive metal regimes. We unveil that the imaginary part of the quasiparticle self-energy obeys a common power law before, at, and after the quantum phase transition, but the power law is nonuniversal, whose exponent is dependent on the disorder strength. More intriguingly, whereas a common power law is also found for the real part of the self-energy before and after the phase transition, a distinctly different behavior is identified at the critical point, characterized by the existence of a nonanalytic logarithmic singularity...

It was shown that saturated liquid densities are a linear function of temperature in the normal liquid range for molecular, polymeric, inorganic, ionic, and metallic liquids and superpose to form a single master curve [1]. We have shown that the existence of master curve is the consequence of rectilinear diameter law.

BACKGROUND: The implantation of rotary blood pumps as ventricular assist devices (VADs) has become a viable therapy for quite a number of patients with end-stage heart failure. However, these rotary blood pumps cause adverse events that are related to blood trauma. It is currently believed that turbulence in the pump flow plays a significant role. But turbulence has not been measured to date because there is no optical access to the flow space in rotary blood pumps because of their opaque casings...

BACKGROUND: There exists rapid growth and inconsistency in the telehealth policy environment, which makes it difficult to quantitatively evaluate the impact of telehealth reimbursement and other policies without the availability of a legal mapping database. INTRODUCTION: We describe the creation of a legal mapping database of state-level policies related to telehealth reimbursement of healthcare services. Trends and characteristics of these policies are presented...

BACKGROUND: Cognitive enhancement is the use of prescription stimulant medicines by healthy individuals for nonmedical use in academic settings. Commonly used cognitive enhancers (CEs) include methylphenidate, amphetamines, and modafinil. To understand the motivation to use CEs, it is important to look beyond prevalence and explore the extent to which attitudes, beliefs, and intentions predict the decision to use CEs. OBJECTIVE: The study aimed to investigate what factors explain the decision to use CEs among tertiary students in New Zealand, using the Theory of Planned Behaviour (TPB)...

Medicaid waivers have been a principal tool of innovation in health policy in the US since at least the mid 1970s. As Republicans seek to give the states more flexibility in their implementation and management of both Medicaid and the Affordable Care Act or its replacement, waiver authority is likely to be one of the key work arounds for avoiding political barriers in the US Senate. While block-granting Medicaid may require 60 senate votes, waiver authority already exists in both Medicaid law and the Affordable Care Act...
