RESUMEN
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.
RESUMEN
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.

Polymyalgia rheumatica (PMR) is an inflammatory disease of individuals aged over 50 years. Because of the concomitant malignancy possibility and the high prevalence of constitutional symptoms seen in this condition, patients with classical clinical picture often experience delay in diagnosis and treatment and are exposed to a wide list of laboratory and imaging procedures. In this study, we aimed to explore the adventure these patients experience from symptom onset to rheumatology clinic. A total of 106 PMR patients (84 women, 22 men) mean age 70.1 ± 8 were analyzed retrospectively. The time period from the onset of symptoms and referral to rheumatology specialists was explored. Diagnostic methods applied to these patients, antibiotic use and hospitalization during this period were recorded. The interval between the onset of the symptoms and admission to rheumatology unit was 13 ± 13 months. In this period, abdominal computed tomography (29.2 %), chest computed tomography (21.7 %), cranial magnetic resonance imaging (18.9 %) and whole-body scintigraphy (3.8 %) were applied to the patients. About 30 % of the patients were hospitalized for a mean period of 7 ± 3 days before referral to rheumatology unit, and 30 % of the patients were given antibiotics. In order to reduce the delay in the diagnosis of PMR and prevent unnecessary and expensive diagnostic methods, education of clinicians about the diagnosis of PMR may be beneficial.
