Questionnaire format of modified frailty index as a predictor for 30-day readmission and length of stay in elderly patients undergoing multi-level lumbar interbody fusion.

Background: Frailty is a spectrum describing a demographic more likely to experience adverse events such as falls, disability, and hospital admission which can be quantified by the modified frailty index (mFI). Several studies have associated increased mFI score with higher rates of hospital readmission and length of stay (LOS). This study tests the predictive value of a frailty questionnaire based on the mFI on LOS and 30-day readmission rates.

Tracheoesophageal puncture and quality of life after total laryngectomy: A systematic review and meta-analysis.

Objective: Total laryngectomy (TL) is a standard induction treatment for laryngeal cancer. Patients have shown decreased quality of life (QOL) following laryngectomy potentially due to its impact on communication. This study is a systematic review of the effects of TEP on QOL in TL patients.

Modified Frailty Index Questionnaire as a Predictor of Discharge Destination in Elderly Patients Undergoing Multilevel Lumbar Interbody Fusion.

Background: Frailty is defined as a state in which depletion of physiologic reserves causes multisystem impairments independent of natural senescence. This phenomenon can be quantified by the 11-point modified frailty index (mFI-11). This study determines whether an 11-point patient questionnaire developed from the mFI-11 can be used as a predictor for discharge destination following multilevel lumbar interbody fusion surgery in elderly patients.

Resilience of genetic diversity in forest trees over the Quaternary.

The effect of past environmental changes on the demography and genetic diversity of natural populations remains a contentious issue and has rarely been investigated across multiple, phylogenetically distant species. Here, we perform comparative population genomic analyses and demographic inferences for seven widely distributed and ecologically contrasting European forest tree species based on concerted sampling of 164 populations across their natural ranges. For all seven species, the effective population size, N, increased or remained stable over many glacial cycles and up to 15 million years in the most extreme cases.

Interventions in root-filled teeth identified in general dental practice: A 6-year longitudinal observational study.

Aim: To investigate what happens to cross-sectionally identified root-filled teeth over a 6-year period, regardless of the time that elapsed since primary root canal treatment, in a cohort of adult patients regularly attending a Public Dental Service. A secondary aim was to investigate how the cumulative events affecting root-filled teeth over the same time were associated with variables obtained from a baseline examination.

Methodology: Adult patients with ≥1 previously root-filled tooth and regularly attending the Public Dental Service in Örebro County were enrolled for study participation in 2015.
