Unlabelled: Otitis media (OM) is one of the most common diagnoses in preschool-age children. Its pathophysiology is poorly understood, but is associated with changes in the nasopharyngeal microbiome, immune system, and presence of allergies. These, in turn, can be affected by early-life antibiotic exposure. Therefore, this study aimed to determine if antibiotic treatment in the first week of life in children born at term was associated with acute otitis media (AOM) and otitis media with effusion (OME) in the first 4-6 years of life.
Methods: A prospective birth cohort of 436 term-born infants was followed up at 4-6 years of age. Parents reported (recurrent) AOM and OME through online questionnaires, sent to parents of 418 eligible children. Doctors' diagnoses of AOM and OME were collected after additional informed consent. Multivariate logistic regression analyses were used to study the association between antibiotic exposure and AOM and OME.
Results: Of the 436 infants, 151 infants received antibiotics in the first week of life. In total, 341 (82%) questionnaires were collected. The parental-reported prevalence was 45% (155/341) for AOM. Of these 155 children, 33 children also had OME (10% of the total cohort). Doctor's diagnoses were obtained from 308 (74%) children, of which 30% (91/308) had AOM. Of these 91 children, 12 children also had OME and 8 children had OME without a diagnosis of AOM (6% of the total obtained diagnoses). Antibiotic treatment in the first week of life was not significantly associated with parent-reported nor doctor-diagnosed (recurrent) AOM and OME in the first 4-6 years of life in the regression models.
Conclusion: Antibiotic treatment in the first week of life was not associated with AOM and OME in the first 4-6 years of life in this prospective cohort of Dutch infants. More insight into the pathophysiology of OM is warranted to determine whether antibiotic-induced microbiome changes play a role in the susceptibility to OM.

Chlorpyrifos (CPF) is one of the most widely used organophosphorus pesticides all over the world. Unfortunately, long-term exposure to CPF may cause considerable toxicity to organisms. Some evidence suggests that the intestinal microbial community may be involved in regulating the toxicity of CPF.

Purpose: Compare the effects of low-intensity and moderate-intensity exercise on physical functioning in breast cancer survivors.
Methods: Women aged 50 + years and post-primary treatment for stage 0 to III breast cancer were randomly assigned to a 6-month low-intensity (LIG) or moderate-intensity (MIG) exercise group. Participants were instructed to walk (low- or moderate-intensity) for 30 min five days a week, followed by flexibility exercises, and do strengthening and balance exercises twice weekly.
Trauma in the courtroom: The role of prior trauma exposure and mental health on stress and emotional responses in jurors.

School of Psychology, University of Bolton, Bolton, UK.
Objectives: Prior research indicates that jury duty can be distressing for some jurors. This study examined: (1) the influence of prior trauma characteristics (type, exposure, time since trauma), medical fear and mental health difficulties on stress and emotional responses during a mock trial and 1 week later; and (2) associations between early stress reactions during a trial on subsequent stress and emotional reactivity after exposure to skeletal evidence and 1 week later.
Methods: Mock jurors (n = 180) completed baseline self-report mental health measures, read a summary of a murder case and were then exposed to graphic skeletal evidence.
