Pectoralis muscle index might be a factor associated with frailty in older women with breast cancer.

BACKGROUND: To investigate the possible relationship between pectoralis muscle (PM) measurement and frailty in older women with breast cancer (BC) (preoperatively defined as stage 1, 2, and 3 diseases). METHODS: This retrospective, observational study was conducted at Konya Training and Research Hospital between June and December 2020. A total of 102 patients [median age 62.5 years, median follow-up period two years] were included in the study. PM measurements were obtained from thorax computerized tomography (CT). Pectoralis muscle index (PMI) was calculated by dividing the PM area by the height square of the patients (cm2/m2). Pectoralis muscle density (PMD) was evaluated using CT findings, including their Hounsfield Units (HU). Frailty status and sarcopenia-risk assessments were done by a telephone interview in September 2020 using the FRAIL index (categorized as robust or nonrobust) and SARC-F questionnaire (classified as no sarcopenia-risk or risk of sarcopenia), respectively. PM measurements were compared between robust and nonrobust patients and between patients with a risk of sarcopenia and no sarcopenia risk. RESULTS: The nonrobust patients had lower pectoralis major muscle index (PMaMI) (p = 0.041) and pectoralis major muscle density(PMaD) (p = 0.020) levels than robust patients in the whole study sample. PMI (p = 0.017) and PMaMI (p = 0.010) levels were significantly lower in the nonrobust patients than in robust patients with early-stage BC. Frailty status was positively correlated with age (rho: 0.621; p < 0.001), BC stage (rho: 0.220; p = 0.026), and SARC-F score (rho: 0.747; p < 0.001), and negatively correlated with PMaMI (rho: -0.197; p = 0.047) and PMaD (rho: -0.237; p = 0.016). There were significant associations between PMaMI (OR: 0.467, 95% Confidence Interval (CI): 0.226-0.962 p = 0.039) and PMI (OR: 0.543, 95% CI: 0.299-0.986 p = 0.045) levels with frailty status (being nonrobust) in regression models. DISCUSSION: In the study, it has been shown that pectoralis muscle assessment might be a related parameter to frailty in older women with breast cancer.

Validity and reliability of Fried frailty phenotype in Turkish population.

BACKGROUND: Frailty is an important, multidimensional geriatric syndrome defined as increased vulnerability to stressors. Fried frailty phenotype (FFP) is one of the most widely used models to define physical frailty. The aim of this study is to investigate the crosscultural validity and reliability of Fried frailty phenotype (FFP) in older Turkish population. METHODS: A total of 450 patients, aged 59 years and over, were included. FFP translated into Turkish was used. Hand grip strength cut-off values that best predict low skeletal muscle mass index (SMI) for Turkish men and women were calculated. A modified version of FFP was created by rescoring FFP according to these cut-off values applicable to Turkish population. Correlation analysis between the frailty assessment by comprehensive geriatric evaluation of clinician experienced in geriatric medicine, and FFP and modified version of FFP were performed for validation. Thirty-five patients underwent frailty assessment with FFP twice for reliability assessment. Inter-rater and intra-rater agreements were investigated. RESULTS: Clinician's decision of frailty status demonstrated significant agreement with the results of FFP, as well as modified FFP. Interrater and intra-rater compliance were good. Best hand grip strength cut-off values for predicting low SMI in older Turkish population were determined as ≤13.6 kg (AUC: 0.841, p < 0.001) for women and ≤27.7 kg for men (AUC: 0.779; p < 0.001). Modified FFP had a good agreement with the FFP. DISCUSSION: FFP is a valid and reliable tool for Turkish population.

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.

Diaphragmatic muscle thickness in older people with and without sarcopenia.

BACKGROUND: Studies in mice have suggested that sarcopenic animals may have atrophic diaphragmatic muscles; however, to date, no clinical studies are available. AIMS: To investigate whether the diaphragmatic thickness is affected in older patients with sarcopenia and if this is associated with impaired respiratory functions. METHODS: Thirty sarcopenic and 30 non-sarcopenic elderly patients aged over 65 were included. All patients underwent comprehensive geriatric assessment. The diagnosis of sarcopenia was made according to the criteria of the European Working Group on Sarcopenia in Older People. Ultrasonographic evaluations of the patients were carried out by an experienced radiologist. Diaphragmatic thickness was measured in three positions: end of deep inspiration, quiet breathing, end of forced expiration. Peak expiratory flow (PEF) rate was evaluated by a peak flow meter. RESULTS: The mean age of the patients was 77 ± 6 years, and 58% were females. Diaphragmatic thickness in three different positions (deep inspiration [2.3 mm (min-max: 1.3-4.1) vs. 2.5 mm (min-max: 1.9-4.9)], quiet breathing [1.8 mm (min-max: 1.0-2.8) vs. 2.00 mm (min-max: 1.3-3.9)] and end of forced expiration [1.1 mm (min-max: 0.7-2.5) vs. 1.5 mm (min-max: 0.5-3.4)]) were found to be thinner in sarcopenic patients compared to non-sarcopenics (p = 0.02, p = 0.02, p < 0.01, respectively). Also, PEF rate results were lower in patients with sarcopenia (245 L/min [min-max: 150-500] vs. 310 L/min [min-max: 220-610], p < 0.01). Diaphragmatic muscle thicknesses in all three positions were independently associated with sarcopenia status of the participants. CONCLUSIONS: Our results suggest that sarcopenia in older people may be associated with reduced diaphragmatic muscle thickness and respiratory functions. Findings are needed to be confirmed in further multicenter studies with big sample sizes.

Comparative Evaluation of Predictive Ability of Comprehensive Geriatric Assessment Components Including Frailty on Long-Term Mortality.

Background: This study aims to compare the predictive value of all comprehensive geriatric assessment (CGA) parameters with the predictive value of frailty assessment (with Edmonton Frailty Scale (EFS) and Fried Frailty Index (FFI)) for long-term mortality, in older adults.Methods: A total of 967 patients were included, consecutively. At the first admission, age, gender, comorbidities, number of drugs, and laboratory values of the patients were recorded. Each patient underwent CGA which consisted of anthropometric measurements, functional, cognitive, mood, nutritional, gait, fall, sleep duration, and frailty assessment. Fifty-seven months after the first admission, CGA parameters were analyzed to determine their predictive abilities on long-term mortality due to all causes, comparatively.Results: The median age was 73 years (range 65-94 years). The median follow-up time was 39.9 months (range 0.5-57.3 months). Serum albumin level, FFI, EFS, instrumental activity of daily living (IADL) score, and walking time were the best predictors of mortality. There was no significant difference between these parameters in predicting mortality.Conclusion: FFI and EFS have similar predictive value for mortality. In busy clinical practice, a new index based on IADL, walking time, and serum albumin level may be an alternative of frailty assessment for predicting mortality.

Frailty is associated with poor sleep quality in the oldest old

Background/aim: Sleep disorders and frailty increase with advancing age, along with physical disabilities, cognitive dysfunction, mood disorders, and social vulnerability. Thus, the study objective was to evaluate the relationship between frailty and sleep quality in the oldest old patients. Materials and methods: In this study, 100 patients aged ≥80 years were assessed using comprehensive geriatric assessment (CGA) including basic activities of daily living (ADL), instrumental ADL, handgrip strength, the Geriatric Depression Scale-15, the Mini- Mental State Examination, and the Mini-Nutritional Assessment-Short Form. The sleep quality and frailty status of the patients were evaluated using the Pittsburgh Sleep Quality Index (PSQI) and the Fried Frailty Index, respectively. Results: The median age of the participants was 84 years (80­92), 55% of them were women, and 41% of them were frail. There was no statistically significant difference between the frail and nonfrail groups in terms of age, sex, and comorbidities (P > 0.050). The frail patients scored poorly according to the CGA tests when compared to the nonfrail ones (P < 0.050). The median score for the PSQI was significantly higher in the frail group, 12 points (3­19) versus 6 points (1­19) in the nonfrail patients (P < 0.001). The PSQI score (odds ratio [OR] of 1.308, 95% confidence interval [CI]: 1.092­1.566, P = 0.004), female sex (OR of 5.489, 95% CI: 1.063­28.337; P = 0.042), and the basic ADL score (OR of 0.383; 95% CI: 0.207­0.706; P = 0.002) were found to be independently associated with frailty using multivariate analysis. Conclusion: Sleep quality was significantly decreased in the oldest old frail patients compared to the nonfrail ones, and poor sleep quality was independently associated with frailty. Evaluating the sleep patterns of the oldest old patients with CGA in daily geriatric practice might help to improve the quality of life of frail patients.

Does Preoperative Comprehensive Geriatric Assessment and Frailty Predict Postoperative Complications?

BACKGROUND: The influence of preoperative comprehensive geriatric assessment and frailty on postoperative morbidity, mortality, delirium were examined. METHODS: A total of 108 patients were evaluated. The Katz Index of Independence in Activities of Daily Living (ADL), the Lawton Brody Instrumental Activities of Daily Living Scale (IADL), the Mini-Nutrition Assessment test (MNA), the Mini-Mental State Examination (MMSE), Yesavage Geriatric Depression Scale (GDS) were performed. Fried Criteria were used to assess physical frailty. We used the Physiological and Operative Severity Scores for the Enumeration of Mortality and Morbidity score (POSSUM), the American Society of Anesthesiologists Score (ASA), and the Charlson Comorbidity Index (CCI) to determine the risk of postoperative morbidity and mortality. Assessment Test for Delirium (4AT) was applied for detection of delirium. RESULTS: The median age was 71 years (min-max: 65-84). IADL (p = 0.032), MNA (p = 0.01), MMSE scores (p = 0.026) were found to be significantly lower in patients with morbidity. POSSUM physiology score (p = 0.005), operative score (p = 0.015) and CCI (p = 0.029) were significantly higher in the patients with morbidity. Patients developed morbidity were found to be more frail (p < 0.001). The patients with delirium were found to have lower IADL (p = 0.049) and MMSE scores (p = 0.004), higher POSSUM physiology score (p = 0.005) and all of them were frail. It was found that frailty (OR = 23.695 95% CI: 6.912-81.231 p < 0.001), POSSUM operative score (OR:1.118 95% CI: 1.021-1.224 p = 0.016) and preoperative systolic blood pressure (OR:0.937%95 CI: 0.879-0.999 p = 0.048) were independently related factors for postoperative morbidity. CONCLUSION: In our study, CGA and frailty in preoperative period were found to be indicators for postoperative morbidity and delirium.

Higher Serum Endocan Level Is Associated with Alzheimer Disease.

BACKGROUND: The novel molecule endocan, which is released by endothelium and is regulated by proangiogenic and proinflammatory cytokines, may have a role in the pathophysiology of Alzheimer disease (AD). The aim of this study was to evaluate the relationship between serum endocan levels and AD. METHODS: A total of 134 patients (47 AD, 42 amnestic mild cognitive impairment [aMCI], and 45 control patients) 65 years of age and older were recruited in this study. Cognitive status of the patients was evaluated by performing the Montreal Cognitive Assessment (MOCA) and the Mini-Mental State Examination (MMSE). Serum endocan levels were measured with an enzyme-linked immunosorbent assay kit. RESULTS: Median serum endocan level was significantly higher in AD patients (380.1 ng/mL) than in both aMCI patients (247.7 ng/mL) and controls (277.6 ng/mL; p < 0.01). Serum endocan level had a weak but significant correlation with MMSE and MOCA scores (r = -0.219 and r = -0.232; p = 0.012 and p = 0.01, respectively). Serum endocan level was detected as a factor independently associated with AD. The cutoff serum level of endocan predicting AD was >288.94 ng/mL in receiver operating characteristic curve analysis (area under the curve 0.71, 95% CI 66.7-90.9, sensitivity 80.9%, specificity 59.8%; p < 0.01). CONCLUSION: Higher serum endocan levels may be associated with the pathogenesis of AD.

Serum markers of inflammation and oxidative stress in sarcopenia.

BACKGROUND: Sarcopenia is a geriatric syndrome characterized by the presence of low muscle mass and function. Possible mechanisms underlying sarcopenia include oxidative stress and elevation of inflammatory cytokines. AIMS: The aim of the study was to evaluate the relationship between sarcopenia and biomarkers that may be involved in its pathogenesis and hence early detection. METHODS: A total of 72 patients (36 sarcopenic and 36 non-sarcopenic) were included in the study. An experienced geriatric team applied comprehensive geriatric assessment to all patients. Anthropometric measures, gait speed and handgrip strength were recorded. Bioelectrical impedance analysis was used to assess skeletal muscle mass. In addition to routine clinical laboratory tests, serum adiponectin, thioredoxin-1 and pentraxin-3 levels were measured. Sarcopenia was defined according to the European Working Group on Sarcopenia in older Adults as the presence of low muscle mass and low muscle function or muscle performance. RESULTS: Sarcopenic patients were more likely to be functionally dependent and had lower scores on comprehensive geriatric assessment tools. Erythrocyte sedimentation rate (ESR) and C-reactive protein levels were significantly higher in the sarcopenic group. There was no significant difference in serum levels of thioredoxin-1 and pentraxin-3. Sarcopenic patients had lower levels of hemoglobin, albumin, total protein, calcium, triglycerides, uric acid and adiponectin (p < 0.05). Hypertension and body mass index were inversely correlated with sarcopenia whereas ESR was positively correlated. DISCUSSION AND CONCLUSION: The present study demonstrated an association of sarcopenia with inflammatory markers CRP, ESR and adiponectin. Long-term prospective studies are warranted to confirm the relationship between markers oxidative stress and age related muscle decline.

Is frailty a prognostic factor for critically ill elderly patients?

AIM: The study aimed to investigate the effects of frailty on clinical outcomes of patients in an intensive care unit (ICU). METHODS: In this prospective study, 122 patients (59 frail, 37 pre-frail and 26 robust) were included. A frailty index (FI) derived from comprehensive geriatric assessment parameters was used for the evaluation. The FI score of ≤0.25 was considered as robust, 0.25-0.40 as pre-frail and >0.40 as frail. The prognostic effects of FI were investigated and FI and APACHE II and SOFA scores, the prognostic scores using in ICU, were compared. RESULTS: Median age of the patients was 71 years old and 50.8 % were male. ICU mortality rate and median length of stay (LOS) were 51.6 % and 8 days (min-max: 1-148), respectively. ICU mortality was higher (69.2, 56.8 and 40.7 %, respectively, p = 0.040) and median overall survival was lower in frail group compared to pre-frail and robust subjects (23, 31 and 140 days, p = 0.013, respectively). Long term mortality over 3 and 6 months in frail patients were 80.8 and 84.6 %, respectively and significantly higher than others. Multivariate analysis showed that LOS in ICU (HR 1.067, 95 % CI 1.021-1.114), SOFA score (HR 1.272, 95 % CI 1.096-1.476) and FI (HR 39.019, 95 % CI 1.235-1232.537) were the independent correlates for ICU mortality (p = 0.004, p = 0.002 and 0.038, respectively). There was a weak but statistically significant positive correlation between APACHE II and FI scores (r = 0.190, p = 0.036). CONCLUSIONS: FI may be used as a predictor for the evaluation of elderly patients' clinical outcomes in ICUs.

Which parameters affect long-term mortality in older adults: is comprehensive geriatric assessment a predictor of mortality?

BACKGROUND: Determining predictors of mortality among older adults might help identify high-risk patients and enable timely intervention. AIMS: The aim of the study was to identify which variables predict geriatric outpatient mortality, using routine geriatric assessment tools. METHODS: We analyzed the data of 1141 patients who were admitted to the geriatric medicine outpatient clinic between 2001 and 2004. Comprehensive geriatric assessment was performed by an interdisciplinary geriatric team. Mortality rate was determined in 2015. The parameters predicting survival were examined. RESULTS: Median age of the patients (415 male, 726 female) was 71.7 years (53-95 years). Mean survival time was 12.2 years (95 % CI; 12-12.4 years). In multivariate analysis, age (OR: 1.16, 95 % CI: 1.09-1.23, p < 0.001), smoking (OR: 2.51, 95 % CI: 1.18-5.35, p = 0.017) and metabolic syndrome (OR: 2.20, 95 % CI: 1.05-4.64, p = 0.038) were found to be independent risk factors for mortality. MNA-SF scores (OR: 0.84, 95 % CI: 0.71-1.00, p = 0.050) and free T3 levels (OR: 0.70, 95 % CI: 0.49-1.00, p = 0.052) had borderline significance. DISCUSSION: The present study showed that the risk conferred by metabolic syndrome is beyond its individual components. Our findings confirm previous studies on the prognostic role of nutritional status, as reflected by MNA-SF. Serum fT3, a simple laboratory test, may also be used in geriatric outpatient clinics to identify individuals at risk. CONCLUSIONS: The results of the study demonstrated the need for addressing modifiable risk factors such as smoking, metabolic syndrome, and undernutrition in older adults.

Phase angle assessment by bioelectrical impedance analysis and its predictive value for malnutrition risk in hospitalized geriatric patients.

BACKGROUND: Phase angle (PhA) value determined by bioelectrical impedance analysis (BIA) is an indicator of cell membrane damage and body cell mass. Recent studies have shown that low PhA value is associated with increased nutritional risk in various group of patients. However, there have been only a few studies performed globally assessing the relationship between nutritional risk and PhA in hospitalized geriatric patients. The aim of the study is to evaluate the predictive value of the PhA for malnutrition risk in hospitalized geriatric patients. METHODS: One hundred and twenty-two hospitalized geriatric patients were included in this cross-sectional study. Comprehensive geriatric assessment tests and BIA measurements were performed within the first 48 h after admission. Nutritional risk state of the patients was determined with NRS-2002. Phase angle values of the patients with malnutrition risk were compared with the patients that did not have the same risk. The independent variables for predicting malnutrition risk were determined. SPSS version 15 was utilized for the statistical analyzes. RESULTS: The patients with malnutrition risk had significantly lower phase angle values than the patients without malnutrition risk (p = 0.003). ROC curve analysis suggested that the optimum PhA cut-off point for malnutrition risk was 4.7° with 79.6 % sensitivity, 64.6 % specificity, 73.9 % positive predictive value, and 73.9 % negative predictive value. BMI, prealbumin, PhA, and Mini Mental State Examination Test scores were the independent variables for predicting malnutrition risk. CONCLUSIONS: PhA can be a useful, independent indicator for predicting malnutrition risk in hospitalized geriatric patients.

Potentially inappropriate prescribing according to the STOPP/START criteria for older adults.

BACKGROUND: The aim of this study was to demonstrate the prevalence and possible predictors of potentially inappropriate medications (PIMs) and potentially prescription omissions (PPOs) according to the Screening Tool of Older Person's Prescriptions (STOPP) and Screening Tool to Alert doctors to Right Treatment (START) criteria in geriatric patients. METHODS: A total of 374 patients (140 male, 234 female) aged ≥65 years were included. Comprehensive demographic and clinical data including age, gender, current diagnoses/medications, comorbid diseases and medical problems were noted. RESULTS: There were 154 (41.2 %) patients with at least one PIM. Most common PIMs were proton pump inhibitors for peptic ulcer disease (9.6 %), calcium-channel blockers (6.4 %) and anticholinergic/antispasmodic drugs (5.9 %) in chronic constipation. There were 274 (73.3 %) patients with at least one PPO. Most common PPOs were calcium-vitamin D supplement in osteoporosis (OP) (39.6 %), statin (22.5 %) and antiplatelet therapies (16.0 %) in diabetes mellitus (DM) with cardiovascular risk factors. PIM was independently associated with female gender (OR = 2.21, p = 0.003), number of medications (OR = 1.35, p < 0.001), Katz scores of daily life activities (OR = 0.87, p = 0.013) and OP (OR = 0.29, p < 0.001). PPO was independently associated with age (OR = 1.06, p = 0.009), Geriatric Depression Scale score (OR = 1.20, p = 0.007), DM (OR = 6.50, p < 0.001), chronic obstructive pulmonary disease (COPD) (OR = 5.29, p = 0.010), number of medications (OR = 0.88, p = 0.019), and incontinence (OR = 0.39, p = 0.043). CONCLUSION: High prevalence of PIMs and PPOs were found in geriatric patients. Number of medications, female gender, and dependency were associated with PIM. Age, higher scores of Geriatric Depression Scale, DM, and COPD were related with PPOs.

[Effect of hypophosphatemia on weaning success from mechanical ventilation]. / Mekanik ventilasyon uygulanan hastalarda ventilatörden ayirma basarisini belirlemede hipofosfateminin yeri.

INTRODUCTION: Hypophosphatemia may cause acute respiratory failure and tissue hypoxia. In this study we investigated the effect of hypophosphatemia on weaning success. PATIENTS AND METHODS: A nested case-control study was conducted in a retrospective cohort of 76 patients who received invasive mechanical ventilation in 2005-2010 in the Medical Intensive Care Unit (MICU) of university hospital. Case patients (failure group) were those who could not be weaned in the first trial or who required post-extubation mechanical ventilation after first extubation. Control patients (success group) were successfully extubated in the first weaning attempt. RESULTS: Frequency of hypophosphatemia (P level < 2.5 mg/dL) at admission was 23.7%. Weaning failure rate was 71.1%. Risk of weaning failure in the presence of hypophosphatemia was 88.9%, whereas risk in the absence of hypophosphatemia was 65.5%, resulting in risk ratio of 1.36 (1.06 - 1.74) (p= 0.096). Mean (± SD) P levels in the success and failure groups were 3.6 ± 1.0 and 3.2 ± 1.0 mg/dL, respectively (p= 0.113). Logistic regression analysis revealed four independent risk factors which were presence of underlying chronic pulmonary disease, high organ dysfunction score (SOFA) at admission, high blood urea nitrogen at the day of weaning trial and low P level at admission to predict weaning failure. Each 1 mg/dL increment in P level resulted in decreased probability of weaning failure with an OR of 0.43 (0.21-0.88). CONCLUSION: In conclusion, a relation between hypophosphatemia and weaning failure was determined which has to be confirmed with prospective cohort and interventional studies with adequate power.

Effect of fosfomycin-induced hypernatremia on patients' hospital stay length and survival.

BACKGROUND AND OBJECTIVE: Hypernatremia is a possible side effect of intravenous fosfomycin. The aim of this study was to investigate the effects of changes in sodium (Na) levels on hospital stay and survival in patients hospitalized in the intensive care unit receiving fosfomycin. SUBJECTS AND METHODS: This study was conducted retrospectively on the files of patients over the age of 60, who were admitted to the Internal Medicine Intensive Care Unit. Plasma sodium levels were observed and documented over a period of 14 days. The patients were divided into two groups (Hypernatremia group Na > 145 mEq/L vs normonatremia group 135-145 mEq/L). In addition, daily sodium changes were noted for 14 days in patients. RESULTS: The mean age of the patients was 75 years. Hospitalization days were longer for hypernatremia patients (31.5 days vs 41 days, p = 0.003). Patients with hypernatremia had an extended duration of stay in the intensive care unit. (21 days vs 31 days p = 0.002). The 1-month survival rate was 61.4% in patients with hypernatremia and 24.9% in patients without hypernatremia (p = 0.004). The absence of hypernatremia increases mortality by 2.09 times (95% CI 1.35-3.23). When discharge and mortality rates were analyzed according to sodium fluctuation, discharged patients exhibited a lower sodium fluctuation (4 min/max (-10/19) vs 6 min/max (-16/32) p < 0.001). CONCLUSION: In conclusion, the strength of our study is that it specifically focuses on the consequences of the sodium fluctuation on patient management and provides results.

Comparison of nutritional risk indices (PNI, GNRI, mNUTRIC) and HALP score in predicting adverse clinical outcomes in older patients staying in an intensive care unit.

Malnutrition among critically ill older patients is a frequent problem in intensive care units (ICUs) and is associated with a higher risk of hospital/ICU length of stay (LOS) and mortality. The aim of this study was to evaluate malnutrition in older patients staying in an ICU using the hemoglobin, albumin, lymphocyte, platelet (HALP) score, modified nutrition risk in the critically Ill (mNUTRIC), prognostic nutritional index (PNI), and geriatric nutritional risk index (GNRI) and to determine the consistency between these tools and their association with clinical outcomes. This cross-sectional retrospective, observational, hospital-based study included 153 older patients (≥65 years of age), who were admitted to an internal medicine ICU. Sequential organ failure assessment (SOFA) scores and acute physiology and chronic health evaluation (APACHE) II were used to assess disease severity. Nutritional status was evaluated using mNUTRIC, GNRI, PNI, and HALP scores, and their association with ICU LOS and mortality was evaluated using ROC and regression analyses. The mortality rate of the patients was 43.1%. The risk of malnutrition was higher among non-survivors, with mNUTRIC scores showing a significant difference between the groups. The scores for all indices, except HALP, showed significant differences between the groups. APACHE-II, SOFA, and mNUTRIC were the strongest prognostic indices for ICU mortality, with mNUTRIC having the highest sensitivity and negative predictive value. The HALP score was not associated with ICU LOS or a significant prognostic factor for mortality. All indices except HALP were good indicators of clinical outcomes in the study population including older patients. Prospective studies in larger and specific patient populations are needed to draw a strict conclusion in this subject.

[Evaluation of methicillin-resistant Staphylococcus aureus bacteremia and comparison of prognosis according to vancomycin MIC values: experience of the last ten years]. / Metisiline dirençli Staphylococcus aureus bakteriyemisinin incelenmesi ve vankomisin MIK degerlerine göre prognozun karsilastirilmasi: Son on yillik deneyim.

Hospital acquired methicillin-resistant Staphylococcus aureus (MRSA) infections are important health problems. Mortality and morbidity rates associated with MRSA infections are increasing with mortality rates being higher for MRSA bacteremia than the other clinical presentations of MRSA infections. Initiation of treatment immediately and use of appropriate antibacterial agents may lead to better clinical outcomes in MRSA bacteremia. The aims of this study were to evaluate the treatment and clinical outcomes of patients with MRSA bacteremia in a tertiary care hospital in Ankara, Turkey. Two hundred forty seven MRSA strains isolated from blood cultures at Hacettepe University Faculty of Medicine, Clinical Microbiology Laboratory between January 2000-December 2010, were evaluated retrospectively. Demographic characteristics, duration of bacteremia, types and duration of antibiotic treatment, presence of other pathogens and all other necessary information were collected from patients' registry. One hundred eighty four patients who had clinically significant bacteremia were analyzed. The mean age of the patients was 55 ± 17 years, of them 44.6% were female and 55.4% were male. The median length of hospital stay was 61 days. The median duration for the development of MRSA bacteremia from the time of admission was 23 days. Overall mortality rate was 54.9%, and mortality rate due to MRSA bacteremia was 19%. The rate of treatment success was 81%. There were 3 (1.6%) patients with vancomycin MIC value of 0.5 mg/L, 140 (76.1%) patients with 1 mg/L and 41 (22.3%) patients with 2 mg/L. The median duration from the time of MRSA bacteremia detection to the time of death was shorter in unsuccessfully treated group than successfully treated group (7 days vs. 30 days, p< 0.001). Thirty days mortality rate was higher in unsuccessfully treated group than successfully treated group (94.3% vs. 50.7%, p< 0.001). The median time interval between positive and negative cultures was 9.5 days. Number of patients with MRSA bacteremia had been decreasing for the last five years (36 patients in 2006, 18 in 2007, 16 in 2008, 12 in 2009 and one in 2010). In multivariate logistic regression analysis, it was shown that, intubation (OR: 5.086, 95% CI: 2.094-12.351; p< 0.001) and malignancy (OR: 2.789, 95% CI: 1.185-6.564; p= 0.019) were independent risk factors for mortality. In this study, it was shown that mortality rate was high in MRSA bacteremia and high MIC value was not an independent risk factor for mortality. It was also noted that when there was no clinical response to vancomycin, the therapy should be changed immediately. To decrease MRSA bacteremia rates in the hospital adherence to rules of infection control and prevention proved to be important factors.

Can Pseudothrombocytopenia be recognised at first look?

Our aim was to determine the laboratory parameters that distinguish pseudothrombocytopenia from true thrombocytopenia. A total of 107 patients who were referred to the adult hematology outpatient clinic with thrombocytopenia and subsequently diagnosed with acute myeloid leukaemia, immune thrombocytopenia and pseudothrombocytopenia were included in our study. Hemogram parameters on admission, platelet value in the control hemogram and peripheral smear findings were recorded. Forty three (40.2%) males and 64 (59.8%) females, were included in our study. There were 25 patients in the leukaemia group, 39 in the immune thrombocytopenia group and 43 in the pseudothrombocytopenia group. Control platelet value and red cell distribution width/platelet ratio were found to be statistically significantly different between the 3 groups. Receiver operating characteristic analysis based on platelet values showed that platelet value ≤ 38,000/µL (86% sensitivity, 78.1% specificity, P < .001), difference between 2 consecutively measured platelet levels ≤ 11. 000/µL (79.1% sensitivity, 79.7% specificity, P < .001), red cell distribution width/platelet ratio ≥ 0.413 (90.7% sensitivity, 78.1% specificity, P < .001) were found to be in favor of true thrombocytopenia. In the differentiation of pseudothrombocytopenia and true thrombocytopenia, the difference between the hemogram parameters at the time of admission and the platelet count in the control blood count may be guiding. This result may reduce patient and physician anxiety and prevent patient referral.
