Rapid determination of colistin resistance in Klebsiella pneumoniae by MALDI-TOF peak based machine learning algorithm with MATLAB.

Introduction: To date, limited data exist on demonstrating the usefulness of machine learning (ML) algorithms applied to MALDI-TOF in determining colistin resistance among Klebsiella pneumoniae. We aimed to detect colistin resistance in K. pneumoniae using MATLAB on MALDI-TOF database.

Attractiveness assessment by orthodontists and laypeople judging female profile modifications of Class II Division 1 malocclusion.

Introduction: The objective of this study was to evaluate the differences in preference between orthodontists and laypeople, judging soft tissue digital alterations of a Class II Division 1 profile of a female patient with mandibular retrognathia, produced by simulated camouflage and mandibular advancement therapy.

Methods: The profile image of a White woman with a Class II Division 1 mandibular retrognathic profile was digitally modified to produce 7 pictures: 1 baseline, 3 stepwise increase in the nasolabial angle of 113°, 121°, and 129°, and 3 stepwise increase in chin-neck length of 51 mm, 54 mm, and 57 mm. Forty-four orthodontists and 162 laypeople assessed these 7 images.

An examination of healthcare-associated infections in elderly patients.

Background/aim: Healthcare-associated infections (HCAIs) are increasing due to the growing numbers of elderly people requiring long-term care and immunosuppressive therapies. The purpose of this study was to examine HCAIs occurring in elderly inpatients in our hospital.Materials and methods: This study prospectively investigated HCAIs developing in all patients hospitalized over a 1-year period.

Differences in attractiveness comparing female profile modifications of Class II Division 1 malocclusion.

Introduction: Our objective was to study the perceptions of laypeople for digital alterations and the amount of nasolabial angle increase that is tolerable and how much chin-neck length increase is needed to achieve a desirable profile in Class II Division 1 women with mandibular retrognathia.

Methods: The profile image of a white woman with a Class II Division 1 mandibular rethrognatic profile was digitally modified to create 6 images: 3 with stepwise increased nasolabial angles of 113°, 121°, and 129°, and 3 with stepwise increased chin-neck distances of 51, 54, and 57 mm. These images were assessed and ranked by 155 white laypeople.

Cost analysis and evaluation of nosocomial infections in intensive care units.

Background/aim: The purpose of this study was to evaluate nosocomial infections occurring in our hospital intensive care units (ICUs) and the risk factors for these, and to determine the effect of these infections on mortality and cost.

Materials And Methods: This retrospective study was performed via infection control committee surveillance data, ICU records, and information processing data between 1 January and 31 December 2013 at the Kanuni Education and Research Hospital.

Results: A total of 309 nosocomial infections were observed in 205 out of 566 patients.
