Pathogen transmission in relation to duration of attachment by Ixodes scapularis ticks
Publication date: Available online 31 January 2018 Source:Ticks and Tick-borne Diseases Author(s): Lars Eisen The blacklegged tick, Ixodes scapularis, is the primary vector to humans in the eastern United States of the deer tick virus lineage of Powassan virus (Powassan virus disease); the protozoan parasite Babesia microti (babesiosis); and multiple bacterial disease agents including Anaplasma phagocytophilum (anaplasmosis), Borrelia burgdorferi and Borrelia mayonii (Lyme disease), Borrelia miyamotoi (relapsing fever-like illness, named Borrelia miyamotoi disease), and Ehrlichia muris eauclairensis (a minor causative agent of ehrlichiosis). With the notable exception of Powassan virus, which can be transmitted within minutes after attachment by an infected tick, there is no doubt that the risk of transmission of other I. scapularis-borne pathogens, including Lyme disease spirochetes, increases with the length of time (number of days) infected ticks are allowed to remain attached. This review summarizes data from experimental transmission studies to reinforce the important disease-prevention message that regular (at least daily) tick checks and prompt tick removal has strong potential to reduce the risk of transmission of I. scapularis-borne bacterial and parasitic pathogens from infected attached ticks. The most likely scenario for human exposure to an I. scapularis-borne pathogen is the bite by a single infected tick. However, recent reviews have failed to make a clear dis...

Conclusion: Distribution of HCV genotypes and subtypes in the United States is more variable than suggested by previous national-level estimates and single-center studies. “Real-world” prevalence data may improve targeting of prevention, screening, and treatment efforts for hepatitis C.
Goals/Background: We aimed to assess temporal changes in the different types of liver disease (LD) cases and outcomes from emergency departments (EDs) across the United States. Study: We used data from the National Inpatient Survey database from 2005 to 2011. The International Classification of Diseases, Ninth Revision (ICD-9) clinical modification codes identified hepatitis C virus (HCV), hepatitis B virus (HBV), alcoholic liver disease (ALD), nonalcoholic fatty liver disease (NAFLD), and other LDs including autoimmune hepatitis. We excluded cases without LD, nonhepatocellular carcinoma–related cancers, human i...

In a rare moment of consensus, health care industry groups uniformly blasted the Trump administration's proposal to penalize legal immigrants for using Medicaid and other public benefit programs, warning it would have broad negative effects on the health care system, government budgets, and public health. The Department of Homeland Security received 210,889 comments on its proposed "inadmissibility on public charge grounds" rule, issued in October, when the comment period ended Monday.

Those engaged in the battle over abortion in the United States are looking out at the thorny landscape and gearing up for what is on the horizon in 2019.
CONCLUSION: The NGT exercise resulted in 21 candidate SLE classification criteria. The next phases of SLE classification criteria development will require refinement of criteria definitions, evaluation of the ability to cluster criteria into domains and evaluation of weighting of criteria.

Conclusions: The current study provides important finding about the performance of the dialysis facilities with ≤10 dialysis stations. Quality improvement strategies are needed, especially for the dialysis facilities with ≤10 stations, to prevent penalties and eventual closure of such facilities due to financial insolvency. Failure to address these issues will increase further disparities in ESRD care.Am J Nephrol 2019;49:64 –73
