Tick-Borne Disease Infections and Chronic Musculoskeletal Pain.

Importance: Tick-borne diseases (TBDs) other than Lyme disease, such as spotted fever group rickettsiosis, ehrlichiosis, and galactose-α-1,3-galactose (α-gal) syndrome, are an emerging public health issue. Long-term sequelae secondary to Ehrlichia or Rickettsia infection are uncommon; however, musculoskeletal symptoms are often attributed to prior tick exposure.

Objective: To evaluate the potential associations between prior exposure to TBDs and musculoskeletal symptoms, including radiographic osteoarthritis.

Clostridium Tetani Bacteremia From a Suspected Cutaneous Source.

Bacteremia is a rare complication of infection. To our knowledge, there are only two case reports to date of , both hypothesized to be secondary to a gastrointestinal source. Herein, we report a case of an elderly man with genome sequence-proven bacteremia from a possible cutaneous source without neuromuscular symptoms.

Outpatient and inpatient anticoagulation therapy and the risk for hospital admission and death among COVID-19 patients.

Background: Coronavirus disease 2019 (COVID-19) is associated with a hypercoagulable state. Limited data exist informing the relationship between anticoagulation therapy and risk for COVID-19 related hospitalization and mortality.

Methods: We evaluated all patients over the age of 18 diagnosed with COVID-19 in a prospective cohort study from March 4th to August 27th, 2020 among 12 hospitals and 60 clinics of M Health Fairview system (USA).

Self-efficacy and ability to read as factors associated with antiretroviral therapy adherence in an HIV-infected population.

Determining the barriers and facilitators of antiretroviral adherence among former and current substance users may be useful in the creation of successful interventions that target this hard-to-reach population. We performed a cross-sectional study of HIV-infected patients (N = 123) prescribed antiretroviral therapy at four Chicago healthcare venues. Bivariate and multivariable analyses were performed to determine factors associated with non-adherence based on definitions of non-adherence (any missed doses) within the past 4-day, 14-day, and 1-month time periods.

Hand and nasal carriage of discordant Staphylococcus aureus isolates among urban jail detainees.

In 928 Dallas County Jail detainees, nasal carriage of Staphylococcus aureus was found in 32.8% (26.5% methicillin-susceptible Staphylococcus aureus [MSSA] and 6.

Asymptomatic carriage of sequence type 398, spa type t571 methicillin-susceptible Staphylococcus aureus in an urban jail: a newly emerging, transmissible pathogenic strain.

Sequence type 398 (ST398) Staphylococcus aureus, frequently carried by livestock, has caused severe human infections and often carries transmissible antibiotic resistance genes. Among methicillin-susceptible S. aureus isolates colonizing Dallas County Jail detainees, 13.

Comparing pulsed-field gel electrophoresis with multilocus sequence typing, spa typing, staphylococcal cassette chromosome mec (SCCmec) typing, and PCR for panton-valentine leukocidin, arcA, and opp3 in methicillin-resistant Staphylococcus aureus isolates at a U.S. Medical Center.

Methicillin-resistant Staphylococcus aureus (MRSA) has become a common cause of skin infections and invasive infections in community dwellers in the United States since the late 1990s. Isolates characterized as USA300 by pulsed-field gel electrophoresis (PFGE) are the predominant strain type in these infections. USA100 and USA500 strains commonly cause health care-associated infections.

Staphylococcus aureus colonization among household contacts of patients with skin infections: risk factors, strain discordance, and complex ecology.

Background: The USA300 methicillin resistant Staphylococcus aureus (MRSA) genetic background has rapidly emerged as the predominant cause of community-associated S. aureus infections in the U.S.

MRSA USA300 at Alaska Native Medical Center, Anchorage, Alaska, USA, 2000-2006.

To determine whether methicillin-resistant Staphylococcus aureus (MRSA) USA300 commonly caused infections among Alaska Natives, we examined clinical MRSA isolates from the Alaska Native Medical Center, Anchorage, during 2000-2006. Among Anchorage-region residents, USA300 was a minor constituent among MRSA isolates in 2000-2003 (11/68, 16%); by 2006, USA300 was the exclusive genotype identified (10/10).

Methicillin-susceptible Staphylococcus aureus as a predominantly healthcare-associated pathogen: a possible reversal of roles?

Background: Methicillin-resistant Staphylococcus aureus (MRSA) strains have become common causes of skin and soft tissue infections (SSTI) among previously healthy people, a role of methicillin-susceptible (MSSA) isolates before the mid-1990s. We hypothesized that, as MRSA infections became more common among S. aureus infections in the community, perhaps MSSA infections had become more important as a cause of healthcare-associated infection.
