Article Synopsis
- The study focused on identifying key immune molecules for diagnosing S. stercoralis infections using serum samples tested with specific antigens (AgS and AgM).
- Results from IgG-ELISA showed decent sensitivity (82.3 to 85.3%) and varying specificity (60.0 to 93.3%), but some cross-reactivity with other helminth infections was noted.
- A specific 140 kDa protein from AgS demonstrated perfect sensitivity and specificity without cross-reactivity, indicating its potential for creating reliable immunodiagnostic tests for strongyloidiasis.
Motor-evoked potential (MEP) monitoring is an electrophysiologic technique useful for testing peripheral motor nerve integrity during cryoablation cases with risk of nerve injury. Previously, neuromonitoring within the magnetic resonance imaging (MRI) suite for cryoablation has not been performed as magnetic needles are used which could cause magnetic field interactions with neuromonitoring leads. We present the first report of a patient who underwent MEP monitoring during MRI-guided cryoablation of a vascular malformation adjacent to the brachial plexus.

Objective: To analyze vaccination coverage up to 24 months of age according to race/ skin color in the 2017-2018 live birth cohort in Natal, Rio Grande do Norte, Brazil.
Methods: Population-based survey conducted in 2020 and 2021. Vaccination coverage up to 24 months of age was estimated according to administered, valid and timely doses.
Objective: To analyze factors associated with full vaccination coverage with valid doses, in children from four state capitals and three other cities in Southeast Brazil.
Method: Analysis of a population survey conducted in 2020-2021, with a sample stratified according to socioeconomic levels of children born in 2017-2018, with data collected through photographic records of their vaccination cards. Odds ratios (OR) and 95% confidence intervals (95%CI) for full vaccination coverage were estimated based on the characteristics of the family, mother and child.
Measles, mumps and rubella vaccination coverage in capitals and interior region municipalities of Northeast Brazil: a household survey in a cohort of children born in 2017 and 2018.

December 2024
Objective: To analyze measles, mumps, and rubella vaccination coverage among children up to 24 months old and factors associated with non-vaccination in a 2017-2018 live birth cohort, in state capitals and large interior region cities in Northeast Brazil.
Methods: Population-based survey analyzing vaccination coverage and sociodemographic factors through logistic regression.
Results: For 12,137 children, vaccination coverage was 79.
