The role of thiol-disulfide homeostasis and ischemia-modified albumin in osteosarcopenia.

BACKGROUND: Oxidative stress results from an imbalance between the induction of reactive oxygen species and the ability of cells to metabolize them. Numerous markers can be used to assess the level of oxidative stress. Thiol-disulfide homeostasis (TDH) and ischemia-modified albumin (IMA) are some of them. The aim of this study is to investigate the role of TDH and IMA, which are indicators of oxidative stress, in older patients with osteosarcopenia (OS). METHODS: The study was conducted cross-sectionally in a geriatrics outpatient clinic. Patients who applied to the outpatient clinic for three months were included in the study. Patients with acute infection, delirium, malignancy, severe liver, heart or kidney dysfunction and who did not give their consent for the study were excluded from the study. The study was conducted with 136 patients. Sarcopenia was diagnosed according to muscle ultrasonography (USG) and handgrip strength (HGS) results. Osteopenia/osteoporosis was diagnosed according to bone mineral densitometry (BMD) results. The combination of osteopenia/osteoporosis and sarcopenia was accepted as OS. RESULTS: Native thiol, total thiol value and nativethiol /totalthiol*100 values were significantly lower in the group with OS (respectively; value = 265 ± 53.8 standard deviation (SD) µmol/L, p = ≤ 0.001; value = 295.33 ± 55.77 SD µmol/L, p = 0.001; value = 90.06 (2.8) interquartile ranges (IQR), p = 0.033). Disulfide/native thiol*100 and disulfide/total thiol*100 values were significantly higher in the group with OS (respectively; value = 5.5 (1.7) IQR, p = 0.033; value = 4.97 (1.4) IQR, p = 0.034). CONCLUSION: In our study, the role of oxidative stress in OS was demonstrated by using TDH as an oxidative stress parameter.

The relationship between urinary incontinence and abdominal muscle thickness in community-dwelling older women undergoing comprehensive geriatric assessment.

PURPOSE: Urinary incontinence (UI) is one of the most common geriatric syndromes in older adults, especially in women. The aim of this study is to show the relationship between urinary incontinence and abdominal muscle thickness measured by muscle ultrasonography (US) in community-dwelling older women adults. METHODS: Eighty-seven community-dwelling older women participated in our study. The presence and the type of UI were recorded. Clinical and demographic characteristics were collected, and a comprehensive geriatric assessment was performed on all participants. Abdominal muscle layer thicknesses were evaluated with muscle US. RESULTS: The prevalence of UI was 55.2% (n = 48) of the study population. The median [IQR] age of the patients in the UI group was 73.0 [69.0-77.5] years and it was 69.0 [67.0-73.0] years in patients without UI (p = 0.007). Abdominal muscle thicknesses were measured smaller in patients with UI than those without UI except for internal oblique muscle thickness. The median [IQR] rectus abdominis muscle thickness was lower in patients with UI than in patients without UI, and the difference was statistically significant (p < 0.003). RA muscle was associated with UI regardless of age, polypharmacy, malnutrition, and frailty (OR: 0.58; 95% CI 0.38-0.89; p = 0.01). CONCLUSIONS: We have shown that UI was independently related to the rectus abdominis muscle thickness, which may reflect the function and mass of the pelvic floor muscles.

A Quality Improvement Study on Delirium Awareness Day: In Pursuit of Missed Delirium Diagnoses.

The current study aimed to screen for delirium in hospitalized older adults and assess the validity of the Turkish version of the 4A's Test (4AT-TR) as a feasible tool to integrate in routine patient care. The point prevalence of delirium according to clinical evaluation in routine practice was detected among all patients aged ≥60 years in 12 pilot wards. Delirium screening was then conducted by two arms: (a) nurses using the 4AT-TR and (b) geriatricians according to Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) criteria. Prevalence of delirium according to clinical impression was 3.3% (n = 4), whereas prevalence was 12.4% (n = 17) according to DSM-5 criteria and 13.8% (n = 17) according to the 4AT-TR. The 4AT-TR performed by nurses had a sensitivity of 66.6% and specificity of 93.5%. Area under the receiver operating characteristic curve for delirium diagnosis was 0.819 (p < 0.001). Most delirium cases remain undetected unless a routine and formal delirium assessment is integrated in hospital care of high-risk patients. The 4AT-TR performed by nurses seems to be a valid tool for determining delirium in hospitalized older adults. [Journal of Gerontological Nursing, 48(8), 43-51.].

Effect of clinical pharmacists' interventions on dementia treatment adherence and caregivers' knowledge.

AIM: Poor adherence with dementia medications is common among patients and caregivers, owing to the absence of perceived effect, polypharmacy, and adverse effects. The aim of this study was to evaluate the effect of clinical pharmacists' interventions on the adherence to dementia treatment and the caregivers' knowledge of dementia. METHODS: This study was conducted at a geriatric outpatient clinic of the university hospital between October 2018 and April 2019. The Morisky Green Levine Adherence Scale (MGLS) to patients or caregivers and the Dementia Knowledge Assessment Tool Version Two (DKAT2) to caregivers were applied at the beginning of the study and 4 months later by a clinical pharmacist. After the scales were applied in the first interview, verbal information about the importance of adherence to dementia treatment, and incorrect answers of caregivers in DKAT2 were provided by the clinical pharmacist. RESULTS: A total of 94 patients and 91 caregivers were included in the study. High adherence to treatment was determined in 70.2% of the patients in the first interview and in 95.7% in the second interview (P < 0.001). The mean score of DKAT2 was 15.53 ± 2.44 in the first interview, while the median score of DKAT2 in the second interview was 19.11 ± 1.25 (P < 0.001). CONCLUSION: The intervention of clinical pharmacists significantly increased the adherence to dementia treatment and the caregivers' knowledge of dementia. Close monitoring of dementia patients and caregivers by clinical pharmacists and collaboration with a multidisciplinary team play an important role in dementia care.

Older Adults With Coronavirus Disease 2019: A Nationwide Study in Turkey.

BACKGROUND: A novel coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) occurred in China in December 2019 and has spread globally. In this study, we aimed to describe the clinical characteristics and outcomes of hospitalized older adults with coronavirus disease 2019 (COVID-19) in Turkey. METHODS: We retrospectively analyzed the clinical data of hospitalized patients aged ≥ 60 years with confirmed COVID-19 from March 11, 2020 to May 27, 2020 using nationwide health database. RESULTS: In this nationwide cohort, a total of 16,942 hospitalized older adults with COVID-19 were enrolled, of whom 8,635 (51%) were women. Mean age was 71.2 ± 8.5 years, ranging from 60 to 113 years. Mortality rate before and after curfew was statistically different (32.2% vs. 17.9%; p < .001, respectively). Through multivariate analysis of the causes of death in older patients, we found that male gender, diabetes mellitus, heart failure, dementia, were all significantly associated with mortality in entire cohort. In addition to abovementioned risk factors, in patients aged between 60 and 79 years, hypertension, chronic kidney disease and cancer and in patients 80 years of age and older malnutrition were also associated with increased risk of mortality. CONCLUSIONS: In addition to the results of previous studies with smaller sample size, our results confirmed the age-related relationship between specific comorbidities and COVID-19-related mortality.

Fever of unknown origin: what is remarkable in the elderly in a developing country?

OBJECTIVES: To investigate fever of unknown origin (FUO) in 97 patients and compare geriatric and adult population. METHODS: We investigated 97 (22 elderly) patients with FUO using the criteria of Petersdorf and Beeson [Medicine 40 (1961) 1] hospitalized between January 1990 and May 2005 at Hacettepe University Hospital. RESULTS: Infectious diseases were the most common cause in the adult (33.3%) and the elderly (45.5%) patients both. Neoplasms were seen in 18.7; 4.5% and collagen vascular diseases were diagnosed in 9.3; 4.5% of the adults and the elderly respectively. Tuberculosis accounted for 60% of all the infectious causes and empirical anti-tuberculous treatment served as a diagnostic method in 43% of the cases with tuberculosis. Lymphadenopathy was more common among the adults with FUO. A diagnosis could be reached in all the elderly patients with a very high erythrocyte sedimentation rate (ESR>100mm/h). At the end of the hospitalization, 14.7% (11/75) of the adult patients and 13.6% (3/22) of the elderly patients died. CONCLUSION: Geriatric patients with FUO usually have characteristics similar to the adult patients with respect to the hospitalization time, diagnosis, and inpatient mortality. Lymphoid organ hyperplasia might be expected less frequently and very high ESR might be a more reliable indicator of systemic disease in the elderly. Empirical anti-tuberculous treatment plays an important diagnostic role in the developing countries with a higher prevalence of tuberculosis.
