PROBLEM: Question: Is acinetobacter baumannii infection in prior ICU bed occupants an independent risk factor for subsequent cases of ventilator-associated pneumonia?
Answer: ICU admission or the hospitalization of patients infected by Acinetobacter baumannii increases the risk of AbVAP by subsequent patients.

PROBLEM: Question: Does thickness of CAD-CAM composite resin overlay influences fatigue resistance of endodontically treated premolars?
Answer: Thick FiltekMZ100 composite resin onlays showed higher fatigue resistance than thin ones and may be associated with fractures that are less subgingival.

SOLUTION: yes

PROBLEM: Question: Does encoding of speech sound at auditory brainstem level in good and poor hearing aid performers?
Answer: The result of the present study suggests that neural encoding of speech sound at the brainstem level might be mediated distinctly in good hearing aid performers from that of poor hearing aid performers. Thus, it can be inferred that subtle physiological changes are evident at the auditory brainstem in a person who is willing to accept noise from those who are not willing to accept noise.

SOLUTION:
yes
