Background: Previously we assessed risk factors for FEV(1) decline in children and adolescents using the Epidemiologic Study of Cystic Fibrosis (J Pediatr 2007;151:134-139); the current study assessed risk factors in adults.
Methods: Risk factors for FEV(1) decline over 3-5.5 years for ages 18-24 and ≥25 years were assessed using mixed-model regression.
Results: Mean rates of FEV(1) decline (% predicted/year) were -1.92 for ages 18-24y (n=2793) and -1.45 for ages ≥25y (n=1368). For the 18-24y group, B. cepacia, pancreatic enzyme use, multidrug-resistant P. aeruginosa, cough, mucoid P. aeruginosa, and female sex predicted greater decline; low baseline FEV(1) and sinusitis predicted less decline. For the ≥25y group, only pancreatic enzyme use predicted greater decline; low baseline FEV(1) and sinusitis predicted less decline.
Conclusions: Risk factors for FEV(1) decline in adults <25 years are similar to those previously identified in children and adolescents; older adults had few statistically significant risk factors.

Foodborne pathogens have always been of public health concern and represent safety issues for food processors. These pathogens develop new ways to overcome antibiotics, survive in different environmental conditions, and the ability to reproduce in many hostile environments configure them as serious health hazards. Considering the huge number of microorganisms, three bacterial representatives were selected to provide a better knowledge about the question of which one is the worst enemy for humans, from the food industry point of view, taking into consideration their multiplication specificity, virulence, and resistance.

To use electronic health record (EHR) data to develop a scalable and transferrable model to predict 6-month risk for diabetic ketoacidosis (DKA)-related hospitalization or emergency care in youth with type 1 diabetes (T1D). To achieve a sharable predictive model, we engineered features using EHR data mapped to the T1D Exchange Quality Improvement Collaborative's (T1DX-QI) data schema used by 60+ U.S.

Menopause is a complex period in women's life, when weight gain and predisposition to obesity are frequent. Moreover, even during menopause transition, women begin to lose lean mass up to 0.5% and, therefore, an increase in the percentage of fat mass with central distribution and an increased risk of metabolic syndrome.

Importance: A high infection burden in early childhood is common and a risk factor for later disease development. However, longitudinal birth cohort studies investigating early-life infection burden and later risk of infection and antibiotic episodes are lacking.
Objective: To investigate whether early-life infection burden is associated with a later risk of infection and systemic antibiotic treatment episodes in childhood.
