Persistent Knee Monoarthritis as a Lyme Disease Presentation: A Diagnostic Challenge - Case Report.

There are several differential diagnoses for knee monoarthritis. We report a patient with recurrent episodes of knee effusion, in which the non-specific clinical condition implied several diagnostic hypotheses, therapeutic inaccuracies, and a delay in implementing adequate treatment. For more than 2 years, the patient underwent different Orthopedics and Rheumatology visits.

Risk factors for healthcare-associated infections and their relationship with waves of the COVID-19 pandemic in an intensive care unit: a nested case-control study.

Objective: To evaluate the risk factors for healthcare-related infections during the COVID-19 pandemic in intensive care units, to investigate the impact of COVID-19 on Central Line-Associated Bloodstream Infection, Catheter-Associated Urinary Tract Infection, and ventilator-associated pneumonia, and to describe healthcare-associated infections in the waves of the COVID-19 pandemic.

Methods: This nested case-control study was conducted in a 137-bed adult medical/surgical intensive care unit at a private hospital in São Paulo, Brazil, between January 11, 2019, and May 21, 2022. Case patients were identified using the Nosocomial Infection Control Committee database and control patients were identified using the intensive care unit's EPIMED system.

Understanding the dynamics of mastitis in milk yield: Decoding onset and recovery patterns in response to mastitis occurrence.

No recent study has attempted to model daily milk losses before and after mastitis onset and the moment when it begins. Thus, we aimed to describe the impact of mastitis on milk production based on mastitis level and moment of occurrence. We used data from 11 dairy farms, and the dataset consisted of 885,759 daily individual milk test records from 3,508 cows in different lactations, with an average milk yield (MY) from January 2017 to December 2022.

Serum folate levels, but not vitamin B12, are associated with slower progression in carotid intima-media thickness in a population exposed to mandatory folic acid fortification.

Background&aims: Folate and vitamin B12 are vitamins involved in one carbon metabolism. Carotid intima-media thickness (cIMT) is a non-invasive test and an early atherosclerosis marker. The relationship between these vitamins and cIMT is not well established.

A multiplex qPCR followed by high-resolution melting analysis for the detection of blood-feeding sources in Culex sp. mosquitoes.

Culex species, such as Culex quinquefasciatus and Culex nigripalpus display a range of feeding habits and act as vectors for pathogens that can cause diseases in both humans and animals. Understanding their feeding habits is pivotal for enhancing disease prevention strategies. The present study introduces the application of two multiplex real-time PCR (qPCR) followed by high-resolution melting (HRM) as a cost-effective and time-efficient alternative.
