“…After reviewing the situation in which there is a single massless self interacting scalar field, we now examine a model in which the real scalar φ has a quartic self coupling λ, a mass m and a Yukawa coupling g with a massless spinor. In this case, the one-loop effective potential is [26] …”

By using the renormalization group (RG) equation it has proved possible to sum logarithmic corrections to quantities that arise due to quantum effects in field theories. In particular, the effective potential V in the Standard Model in the limit that there are no massive parameters in the classical action (the "conformal limit") has been subject to this analysis, as has the effective potential in a scalar theory with a quartic self coupling and in massless scalar electrodynamics. Having multiple coupling constants and/or mass parameters in the initial action complicates this analysis, as then several mass scales arise. We show how to address this problem by considering the effective potential in a Yukawa model when the scalar field has a tree-level mass term. In addition to summing logarithmic corrections by using the RG equation, we also consider the consequences of the condition V ′ (v) = 0 where v is the vacuum expectation value of the scalar. If V is expanded in powers of logarithms that arise, then it proves possible to show that either v is zero or that V is independent of the scalar. (That is, either there * fbrandt@usp.br † fchishtie@uwo.ca ‡ dgmckeo2@uwo.ca 1 is no spontaneous symmetry breaking or the vacuum expectation value is not determined by minimizing V as V is "flat".)

“…For a mobile patient population – many with current or history of IDU, homelessness, or incarceration – a public health approach is indicated to counter structural barriers inhibiting the HCV care continuum. 17 , 18 Impediments to timely diagnosis and care often include patients’ limited access to care, prohibitive costs, and insufficient provider training or incentive to screen and treat HCV infection. Incorporating point-of-care HCV testing and counseling into existing HIV screening infrastructure can counter these barriers by relying on public health advocates already trained to navigate patients to care in both clinical and non-clinical settings.…”

IntroductionAn estimated 25% of the 1.2 million individuals living with human immunodeficiency virus (HIV) in the U.S. are co-infected with hepatitis C (HCV). The Centers for Disease Control and Prevention recommends HCV testing for high-risk groups. Our goal was to measure the impact of bundled HIV and HCV testing vs. HIV testing alone on test acceptance and identification of HCV and HIV.MethodsWe conducted a two-armed, randomized controlled trial on a convenience sample of 478 adult patients in the Jacobi Medical Center emergency department from December 2012 to May 2013. Participants were randomized to receive either an offer of bundled HIV/HCV testing or HIV testing alone. We compared the primary outcome, HIV test acceptance, between the two groups. Secondary outcomes included HIV and HCV prevalence, and HCV test acceptance, refusal, risk, and knowledge.ResultsWe found no significant difference in HIV test acceptance between the bundled HCV/HIV (91.8%) and HIV-only (90.6%) groups (p=0.642). There were also no significant differences in test acceptance based on gender, race, or ethnicity. A majority of participants (76.6%) reported at least one HCV risk factor. No participants tested positive for HIV, and one (0.5%) tested positive for HCV.ConclusionIntegrating bundled, rapid HCV/HIV testing into an established HIV testing program did not significantly impact HIV test acceptance. Future screening efforts for HCV could be integrated into current HIV testing models to target high-risk cohorts.

“…Previous data have supported the use of such programs. HCV continuum of care teams that include patient navigators improve screening and linkage-to-care [7,[16][17][18]. Furthermore, physician education and clinical support, including EHR-based tools, are likewise critical to improving testing rates [19][20][21][22][23][24].…”
