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 the severity of insomnia and falls in the elderly.

BACKGROUND: Insomnia is associated with depression, cognitive impairment, hypertension, myocardial infarction, stroke, metabolic syndrome and prostate cancer in the elderly. The aim of this study is to investigate the relationship between severity of insomnia and falls. METHODS: This cross-sectional study was conducted in a single geriatric outpatient clinic at a university teaching hospital. Patients with active infection, who could not complete insomnia severity index (ISI) test because of cognitive impairment and who could not perform handgrip strength and timed up and go (TUG) tests were excluded from the study. RESULTS: A total of 215 patients were included in this study. Logistic regression analysis showed that there is significant relationship between poorer TUG performance, mild insomnia, moderate insomnia, severe insomnia and falls in the elderly (odds ratio (OR) = 1.04, CI: 1.00-1.09, P = 0.041, OR = 2.43, CI: 1.22-4.85, P = 0.011, OR = 3.84, CI:1.35-10.94, P = 0.012, OR = 5.81, CI:1.00-33.72, P = 0.050). CONCLUSIONS: In this study we showed that there is a relationship between the severity of insomnia and falls.

NRS-2002 and mNUTRIC score: Could we predict mortality of hematological malignancy patients in the ICU?

BACKGROUND: Malnutrition is a problem that greatly affects patients with hematological malignancy (HM) throughout the course of illness. Intensity of the malignancy treatment, inadequate energy intake, complex procedures such as hematopoietic stem cell transplantation, and treatment side effects are contributing factors for malnutrition in HM patients. The aim of this study was to compare the accuracy of the modified Nutrition Risk in Critically Ill (mNUTRIC) score and Nutrition Risk Screening 2002 (NRS-2002) in predicting hospital and long-term mortality of HM patients in the intensive care unit (ICU) and to identify effects of malnutrition on ICU mortality. METHODS: This prospective observational cohort study was conducted in a university teaching hospital tertiary ICU service. During the study period, 112 HM patients who were >18 years old were admitted to the ICU. We excluded the patients who were discharged or died within 24 h from the statistical analysis. The patients were followed for 3 years after discharge for long-term mortality. RESULTS: Twenty-nine patients died within 24 h of admission and were excluded from the study; therefore, statistical analysis was done for 81 patients. Logistic regression analysis demonstrated that high malnutrition risk, according to the NRS-2002 score, was associated with greater odds of ICU mortality (P = 0.002, odds ratio = 19.16). CONCLUSION: In this study, we showed that NRS-2002 is superior to mNUTRIC score in predicting ICU mortality in patients with HMs. mNUTRIC score and NRS-2002 were not superior to each other in predicting long-term mortality.

Predictive ability of the G8 screening test to determine probable sarcopenia and abnormal comprehensive geriatric assessment in older patients with solid malignancies.

BACKGROUND: Pre-treatment evaluation for sarcopenia is recommended in cancer patients. New screening tests that are less time-consuming and can identify patients who will potentially benefit from geriatric assessment are being developed; the G8 geriatric screening test is one such example. We aimed to investigate whether the G8 screening test can detect probable sarcopenia and is valid and reliable compared to a comprehensive geriatric assessment (CGA) in Turkish older adults with solid cancers. METHODS: We included solid cancer patients referred to a single center. Probable sarcopenia and abnormal CGA were defined as low handgrip strength. Cut-offs for handgrip strength in the Turkish population have been previously determined to be 32 kg for males and 22 kg for females and impairment in at least one of the CGA tests, respectively. The CGA tests comprised KATZ Basic Activities of Daily Living Scale Lawton-Brody Instrumental Activities of Daily Living Scale, Mini-Mental-State Examination Scale, Geriatric Depression Scale-15, and Mini-Nutritional Assessment Short Form. Receiver operating characteristic curve analyses evaluated the test's predictive ability. Intra-rater and inter-rater reliabilities were assessed. RESULTS: The median age of the 76 patients included was 72 (65-91) years. There was a moderate correlation between handgrip strength and the G8 test total score. The sensitivity and specificity of the G8 test to detect probable sarcopenia alone (cut off score = 12.5) were 50 and 92%, respectively (AUC: 0.747; p < 0.001); to determine abnormal CGA plus probable sarcopenia (cut off score = 13) were 93.33 and 86.89%, respectively (AUC: 0.939; p < 0.001); and to detect abnormal CGA alone (cut off score = 14) were 79.63 and 95.45%, respectively (AUC: 0.893; p < 0.001). The G8 test results agreed with those of CGA (κ = 0.638; p < 0.001). Both inter- and intra-rater assessments of G8 scores revealed a strong agreement (Interclass correlation coefficient = 0.979, p < 0.001 and ρ = 0.994, p < 0.001, respectively). CONCLUSIONS: The Turkish version of the G8 test is a good screening tool to detect probable sarcopenia alone and in conjunction with abnormal CGA in older patients with solid malignancies. The G8 screening tool may thus be useful in detecting probable sarcopenia in Turkish older adults with solid cancers.

Validity and reliability of the G8 screening test in older non-cancer patients.

PURPOSE: A comprehensive geriatric assessment (CGA) is a time-consuming approach that requires a special team and a screening test, whereas the G8 screening test is a practical and validated test for screening cancer patients. This study aimed to evaluate the validity and reliability of the G8 test in older patients without cancer and to investigate its concordance with CGA in an outpatient clinic. METHODS: Two hundred older patients were included in the study. CGA and G8 tests were performed, and the concordance between them was evaluated for scale validity using Spearman correlation coefficients (r) and kappa analyses. Patients who obtained scores lower than the predefined cutoff values in at least one of the CGA tests were considered to have an abnormal CGA. Inter-rater and intra-rater concordance were assessed for reliability. RESULTS: Of the 200 patients, 57.4% were female, and the median age was 73 (63-93) years. There was a strong concordance between the CGA and G8 screening test (kappa: 0.630; p < 0.001). Inter-rater and intra-rater concordance in the reliability assessments were high (kappa: 0.886; kappa: 875; p < 0.001, respectively), and inter- and intra-clinician assessments of the G8 scores revealed significant correlations (r = 0.962 and r = 0.976, respectively; p < 0.001). CONCLUSION: The G8 screening test is a valid and reliable tool for older adults without malignancy. It is a quick and practical test for physicians who frequently admit older patients.

Pericardial, pleural and peritoneal involvement in a patient with primary gastric mantle cell lymphoma.

Primary gastric mantle cell lymphoma is a rare form of gastointestinal tumour. Although peritoneal carcinomatosis accompanied by malignant ascites is relatively common, mantle cell lymphoma presenting with ascites is rare. Also, effusions involving pericardial and pleural cavities are uncommon during the course of lymphomas. We report the first case in which pericardial, pleural and peritoneal effusion of a primary gastric mantle cell lymphoma.

A Pregnant Woman Who Underwent Laparoscopic Adrenalectomy due to Cushing's Syndrome.

Cushing's syndrome (CS) may lead to severe maternal and fetal morbidities and even mortalities in pregnancy. However, pregnancy complicates the diagnosis and treatment of CS. This study describes a 26-year-old pregnant woman admitted with hypertension-induced headache. Hormonal analyses performed due to her cushingoid phenotype revealed a diagnosis of adrenocorticotropic hormone- (ACTH-) independent CS. MRI showed a 3.5 cm adenoma in her right adrenal gland. After preoperative metyrapone therapy, she underwent a successful unilateral laparoscopic adrenalectomy at 14-week gestation. Although she had a temporary postoperative adrenal insufficiency, hormonal analyses showed that she has been in remission since delivery. Findings in this patient, as well as those in previous patients, indicate that pregnancy is not an absolute contraindication for laparoscopic adrenalectomy. Rather, such surgery should be considered a safe and efficient treatment method for pregnant women with cortisol-secreting adrenal adenomas.
