Serological diagnosis of toxoplasmosis requires quantitative tests, most of which are automated techniques. The automated techniques have several advantages: they are adapted to the routine analysis of large quantities of samples and produce quantitative and reproducible IgG and IgM results, particularly for the Architect technique, with excellent specificity for IgG (near 100%) and excellent sensitivity for IgM (6–8).

Although CVB3-induced myocarditis had been considered to be CD4+ T lymphocyte–mediated inflammatory heart disease4,5, accumulating data indicates that macrophages represent the major inflammatory infiltrates and play a pathogenic role in the development of VM. Macrophages, as master regulators of inflammation, are highly plastic and can differentiate into M1 (classically-activated) or M2 (alternatively-activated) macrophages6,7 depending on signaling conditions. M1 macrophages, induced by lipopolysaccharide (LPS) and interferon-γ (IFN-γ), typically produce copious amounts of pro-inflammatory cytokines (tumor necrosis factor [TNF]-α, interleukin [IL]-12) and generate reactive oxygen species (ROS). As such, M1 macrophages are associated with inflammation and tissue destruction. On the other hand, M2 macrophages, induced by Th2-produced IL-4 and IL-13, secrete high levels of anti-inflammatory cytokines (IL-10) and are characterized by increased arginase1 (Arg-1) activity and surface expression of macrophage mannose receptor (MMR, CD206) and macrophage galactosetype C-type lectin (MGL, CD301). Functionally, M2 macrophages show an anti-inflammatory phenotype associated with tissue repair and angiogenesis8,9,10,11,12,13.

Culture.The clinical pathogen identification methods were completed in each of the participating countries (The Gambia, Mali, Kenya, and Bangladesh) and were described in detail by Panchalingam et al. (7). Briefly, the stool specimens were collected in sterile containers and examined within 24 h of passage. The stool specimens were stored at 2 to 8°C while in transit to the laboratory. Conventional bacteriological, immunological, and molecular methods were used to identify bacterial pathogens. Vibrio cholerae, Vibrio parahaemolyticus, Aeromonas spp., C. jejuni, Campylobacter coli, Salmonella spp., Shigella spp., and diarrheagenic E. coli were isolated from the appropriate selective media and identified by standard biochemical tests. The standard protocol was to test three putative lactose-positive and indole-positive E. coli-like colony morphologies selected from the MacConkey plate for diarrheagenic E. coli as previously described (7). The species and subtypes were confirmed by serotyping (for Shigella and Salmonella spp.) with commercially available antisera (Reagensia, Solna, Sweden, and Denka Seiken, Tokyo, Japan) and by PCR tests for both the heat-labile and heat-stable enterotoxin producers of ETEC, typical and atypical EPEC, and EAEC.

On the other hand, what is the false negative risk; that is, the chance that identification of a high-grade tumor might be delayed because a man was not referred for a biopsy based on the results of this blood test?

Taking into account the high levels of Mrp8/14 in inflammatory disease and infection, immune intervention that targets this complex may be a successful strategy to block an uncontrolled inflammatory response seen in severe sepsis and septic shock. The inhibition of release of this inflammatory mediator may represent a promising therapeutic option. Alternatively, using a low dose of Mrp8 to induce a state of immune “tolerance” to subsequent inflammatory stimuli, as seen in the case of the TLR4 agonist LPS, may represent another viable therapeutic option. In the present study we attempted to investigate the potential role of Mrp8 in inducing self-tolerance and cross-tolerance to bacterial infection.

Assuming that “this country” is Israel, it’s the homeland of its Jewish and non-Jewish Israeli citizens, immigrants, expats and refugees, equally. If it is the homeland of (all) Jews, that’s only because it currently exists as a religion-supremacist “Jewish State” construct.

Prostate cancer is a very serious disease among older men. According to the American College of Physicians, one out of 16 men will receive a diagnosis of prostate cancer in their lifetimes, although only 2.9% will die of it, most of them older than 75. Nonetheless, PSA screening does not help: it carries a significant risk of harm. In this week’s NEJM article, Pinsky et al. conclude:

Given previous associations of the evolution of neutralizing Ab breadth in the setting of high immune activation, low CD4 counts, and high viral loads (12, 14), we aimed to dissect the potential involvement of changes in IC biology in a group of spontaneous controllers of HIV (≤2000 copies/ml), a fraction of whom developed bNAb responses, despite the absence of high levels of plasma antigenemia (15). Despite lower viremia, previous studies demonstrated that equal numbers of controllers evolve neutralization breadth (15) compared with normal progressors (12, 14). Seventy-one participants were included in this study, with neutralization breadth ranging from 9 to 100% coverage of a panel of 11 tier 2/3 viruses (neutralizers) that were compared with a matched group of 60 participants with no evidence of neutralizing Ab breadth (0% neutralizing activity across 11 tier 2 and tier 3 viruses; non-neutralizers). The two groups were matched for duration of infection, viral loads, and CD4 counts.

I learned a new word this week: pseudoepidemic. That’s what happens when people start looking really hard for a disease that didn’t get much attention earlier, and then–not surprisingly–the disease suddenly becomes much more prevalent.

I think you are spot on that psychologically many people who do wrong tend to fear the same being done to them. Your explanation seems right to me. There are other possible explanations for this in my profession. One of them is that once you know something can be done (because you maybe did it), then you know it *can* be done and if it can be done, it can be done to you too… We don’t tend to fear anything we haven’t already experienced or otherwise witnessed. Being a perpetrator falls into the category of knowing it is possible… I think your explanation is better though…
