Delirium is associated with increased mortality in the geriatric population.

OBJECTIVE: The aim of this study was to investigate the prevalence of delirium and its association with mortality rates in elderly inpatients. METHODS: The medical records of 1435 patients over 65 years old who were treated at a regional university hospital and were referred to the university's Consultation and Liaison Psychiatry Clinic for psychological evaluation were retrospectively analyzed. Patients with and without a diagnosis of delirium were compared. The National Survival Database was used to determine mortality rates. RESULTS: The prevalence of delirium was 25.5%. The delirium group was older (p < .0001) and had a larger proportion of males (p < .0001). Mortality rate was higher in the delirium group at 1, 2, 3, 4, and 5 years (p < .0001 for all). Age, gender, lower urinary system diseases, chronic liver disease, solid hematologic malignancy, infections, and Alzheimer's disease emerged as significant parameters associated with mortality. Multivariate analysis of these parameters indicated that comorbid diseases (lower urinary system diseases, chronic liver disease, solid hematologic malignancy, infections, and Alzheimer's disease) are risk factors for mortality independent of demographic data such as age and gender. CONCLUSIONS: Independent of all other factors, delirium is associated with higher mortality risk.

Autopsies in the elderly: Erzurum study.

INTRODUCTION: Clinical and forensic autopsies are the best methods for determining cause of death. The aim of this study was to determine demographic and etiologic characteristics in geriatric forensic cases analyzed in Erzurum, Turkey. MATERIALS AND METHODS: Autopsy reports and prosecution documents of decedents aged 65 and older autopsied in the Morgue Specialization Department of the Forensic Medicine Institute, Erzurum Division between January 1, 2010 and December 31, 2015 were screened retrospectively. RESULTS: The study included 399 subjects with a mean age of 74.38 ± 7.28 years. A large proportion of the subjects were in the young and middle old age group (n = 218, 54.63%) and male (n = 286, 71.68%). Autopsy was performed on 198 (49.62%) of the subjects, cause of death was determined by post-mortem external examination in 199 (49.87%), and documents were unavailable for 2 subjects. Cause of death was determined as natural in 130 (32.58%) of the decedents and unnatural in 269 (67.42%). The most common natural cause of death was cardiovascular disease (n = 94, 76.4%). Unnatural causes of death included accident in 223 (82.90%), suicide in 25 (9.30%) and homicide in 21 (7.80%) of the decedents. A large proportion of the accidents were traffic accidents (n = 120, 53.80%). The most common method of committing suicide was hanging (n = 15, 60%), whereas homicides were most often committed by blunt force trauma (n = 9, 42.86%). CONCLUSION: Our data are consistent with the literature, allowing for some variation based on regional sociocultural characteristics.

Myostatin Gene Polymorphism in an Elderly Sarcopenic Turkish Population.

INTRODUCTION: One of the genetic contributors to sarcopenia predisposition is Myostatin (MSTN), which in humans encodes myostatin, a 376 amino acid growth factor protein that negatively regulates muscle growth. The aim of this study was to investigate MSTN polymorphisms in an elderly sarcopenic population in Turkey and determine how they relate to sarcopenia. MATERIALS AND METHODS: The study included nursing home residents who were aged ≥65 years. Sarcopenia screening was performed using "The European Working Group on Sarcopenia in Older People" guidelines. Blood sample was taken from each participant and DNA was obtained from the peripheral blood. MSTN polymorphisms were genotyped by polymerase chain reaction and restriction fragment length polymorphism methods. RESULTS: A total of 152 elderly patients were included in the study. The rate of sarcopenia was determined to be 41.4%. The DNA nucleotide sequence of all three MSTN exons was determined for each study participant. Among the 152 patients, only 6 (3.9%) showed an MSTN K153R heterozygous mutation. Among these, three participants were sarcopenic and three were nonsarcopenic. No statistically significant difference in the polymorphism frequency between the sarcopenic and control groups was observed (p=0.664). CONCLUSIONS: MSTN genotyping revealed that only 3.9% (6/152) of participants had the MSTN K153R heterozygous mutation. Despite the detection of this mutation in the study group, no relationship was found between this mutation and sarcopenia.
