Discovery of Streptomyces species CS-62, a novel producer of the Acinetobacter baumannii selective antibiotic factumycin.

Narrow-spectrum antibiotics are of great interest given their ability to spare the microbiome and decrease widespread antibiotic resistance compared to broad-spectrum antibiotics. Herein, we screened an in-house library of Actinobacteria strains for selective activity against Acinetobacter baumannii and successfully identified Streptomyces sp. CS-62 as a producer of a natural product with this valuable activity. Analysis of the cultures via high-resolution mass spectrometry and tandem mass spectrometry, followed by comparison with molecules in the Natural Product Atlas and the Global Natural Products Social Molecular Networking platform, suggested a novel natural product. Genome mining analysis initially supported the production of a novel kirromycin derivative. Isolation and structure elucidation via mass spectrometry and Nuclear Magnetic Resonance (NMR) analyses revealed that the active natural product was the known natural product factumycin, exposing omissions and errors in the consulted databases. While public databases are generally very useful for avoiding rediscovery of known molecules, rediscovery remains a problem due to public databases either being incomplete or having errors that result in failed dereplication. Overall, the work describes the ongoing problem of dereplication and the continued need for public database curation.

Factors associated with the permission for child vaccination in the context of the COVID-19 pandemic.

OBJECTIVE: To identify factors associated with permission for child vaccination in the context of the COVID-19 pandemic. METHOD: Cross-sectional study, with parents/guardians of children aged up to 1 year, 11 months and 29 days, aged 18 years or older, with internet access and residents of the state of Alagoas. The collection was conducted between June 2021 and April 2022, using a structured instrument via Google forms®. Fisher's Exact and Pearson's chi-square statistical tests were used. RESULTS: A total of 94 parents/guardians participated. There was an association between permission for child vaccination during the COVID-19 pandemic and higher education level of parents/guardians, with the lack of an educational bond with the child, and between parents/guardians who would allow the application of the COVID-19 vaccine. CONCLUSION: Permission for child vaccination in the context of the COVID-19 pandemic was associated with higher education level of parents/guardians and the absence of educational bond of the child.

Intramuscular injection safety without aspiration in the ventro-gluteal region during vaccination: randomized clinical trial / Seguridad de la inyección intramuscular sin aspiración en la región ventroglútea durante la vacunación: ensayo clínico aleatorizado / Segurança da injeção intramuscular sem aspiração na região ventro-glútea durante a vacinação: ensaio clínico randomizado

ABSTRACT Objectives: to compare adverse events after administrating hepatitis A vaccine intramuscularly in the ventro-gluteal region between techniques with and without aspiration. Methods: randomized double-blind clinical trial, using hepatitis A vaccine (inactivated) in the ventro-gluteal region, with a sample of 74 participants in the intervention group, vaccinated with the slow injection technique without aspiration, and 74 participants in the control group undergoing slow injection with aspiration. Daily assessment of participants was carried out in the 72 hours after vaccination, in order to ascertain local, systemic adverse events, local and contralateral temperatures. Results: the occurrence of local and systemic adverse events was homogeneous between the groups in the three days after vaccination (p>0.05). There was no influence of sex, race, pre-existing disease and use of medication. Conclusions: the intramuscular vaccination technique without aspiration in the ventro-gluteal region is safe for adverse events following immunization compared to the conventional technique with aspiration.

Reliability of a measurement of neck flexor muscle endurance.

BACKGROUND AND PURPOSE: Neck flexor muscle endurance has been negatively correlated with cervical pain and dysfunction. The purposes of this study were to determine rater reliability in subjects both with and without neck pain and to determine whether there was a difference in neck flexor muscle endurance between the 2 groups. SUBJECTS: Forty-one subjects with and without neck pain were enrolled in this repeated-measures reliability study. METHODS: Two raters used an isometric neck retraction test to assess neck flexor muscle endurance for all subjects during an initial session, and subjects without neck pain returned for testing 1 week later. RESULTS: For the group without neck pain, intrarater reliability was good to excellent (intraclass correlation coefficient [ICC(3,1)]=.82-.91), and interrater reliability was moderate to good (ICC[2,1]=.67-.78). The associated standard error of measurement (SEM) ranged from 8.0 to 11.0 seconds and from 12.6 to 15.3 seconds, respectively. For the group with neck pain, interrater reliability was moderate (ICC[2,1]=.67, SEM=11.5). Neck flexor muscle endurance test results for the group without neck pain (mean=38.95 seconds, SD=26.4) and the group with neck pain (mean=24.1 seconds, SD=12.8) were significantly different. DISCUSSION AND CONCLUSION: Reliability coefficients differed between the 2 groups and ranged from moderate to excellent and improved after the first test session. The interrater reliability of data obtained with the neck flexor muscle endurance test in people with neck pain must be improved in order for clinicians to distinguish a clinically meaningful change from measurement error. Neck flexor muscle endurance was both statistically and clinically greater for subjects without neck pain than for those with neck pain.
