Validation of the revised 9-scale clinical frailty scale (CFS) in Greek language.

BACKGROUND: Among many screening tools that have been developed to detect frailty in older adults, Clinical Frailty Scale (CFS) is a valid, reliable and easy-to-use tool that has been translated in several languages. The aim of this study was to develop a valid and reliable version of the CFS to the Greek language. METHODS: A Greek version was obtained by translation (English to Greek) and back translation (Greek to English). The "known-group" construct validity of the CFS was determined by using test for trends. Criterion concurrent validity was assessed by evaluating the extent that CFS relates to Barthel Index, using Pearson's correlation coefficient. Both inter-rater and test-retest reliability were assessed using intraclass correlation coefficient. RESULTS: Known groups comparison supports the construct validity of the CFS. The strong negative correlation between CFS and Barthel Index (rs = - 0,725, p ≤ 0.001), supports the criterion concurrent validity of the instrument. The intraclass correlation was good for both inter-rater (0.87, 95%CI: 0.82-0.90) and test-retest reliability (0.89: 95%CI: 0.85-0.92). CONCLUSION: The Greek version of the CFS is a valid and reliable instrument for the identification of frailty in the Greek population.

Multiple osteolytic lesions due to Double-Expressor Primary non-Hodgkin Lymphoma of the Bone.

Primary non-Hodgkin lymphoma of the bone (PLB) is a rare type of non-Hodgkin's lymphoma (NHL) that affects the skeletal system with or without regional lymph node involvement. We present the case of a 74-year-old female patient with pain due to multifocal osteolytic lesions. The diagnosis of diffuse large B-cells (non-GCB) phenotype was made by clinical, laboratory, histopathological examination accompanied by an extensive immunohistochemical profile of one of the skeletal lesions.

A Case Report of Successful Conservative Treatment for Infective Endocarditis Caused by Gemella sanguinis.

Infective endocarditis is defined as an infection of a native or prosthetic heart valve, the endocardial surface of the heart, or an indwelling cardiac device. Among the miscellaneous emerging opportunistic bacteria that can cause infective endocarditis is Gemella sanguinis that has been reported as a cause of infective endocarditis in nine cases in the past. All of the survivors received antimicrobial therapy and underwent prosthetic valve replacement surgery while, in general, a proportion of 40-50% of the patients with infective endocarditis underwent valve surgery. Our case illustrates that valve surgery, in combination with the administration of antibiotics, is not the only therapeutic option for infective endocarditis due to Gemella sanguinis and that a conservative management with prolonged administration of parenteral antibiotics under close supervision of the patient can be an option.

Predictors of Inappropriate Proton Pump Inhibitors Use in Elderly Patients.

Introduction. Overutilization of Proton Pump Inhibitors (PPIs) both in ambulatory care and in the inpatient setting possesses economic implications and increases the risk for adverse drug reactions. This study was undertaken to identify factors associated with inappropriate PPI use among consecutively unplanned admissions of elderly patients at the time of admission. Materials and Methods. In 758 patients (54.2% women), mean age 80.3±8.0 (M±1SD), demographic characteristics, and medical and medication history were recorded. Parametric tests and multiple logistic regression analysis were applied to identify the predictors of inappropriate PPI use. Results. 232 patients (30.6%) were receiving PPIs. 37 (4.9%) were receiving PPIs appropriately and 195 (25.7%) were receiving PPIs without a proper indication. Consequently, PPIs prescribing was inappropriate in 195/232 (84%). Moreover, 512 patients (67.5%) were not receiving PPIs appropriately and 14 patients (1.8%) were not receiving PPIs but they had a proper indication. When we compared patients receiving PPIs without a proper indication with those who were not receiving PPIs, a statistical difference was found according to Charlson Comorbidity Index (p≤0.001, U=37922.00), number of diseases (p≤0.001, U=33269.00) and medications (p≤0.001, U=31218.50), Katz Index score (p=0.01, U=45328.00), and the use of blood thinners (p≤0.001, χ 2=21.15). In multivariate analysis the only independent predictor of inappropriate PPI use was the number of medications (p=0.001, OR=1.16, 95%CI 1.06-1.27). Conclusions. The main predictor of inappropriate PPI use was the number of received medications. Εfforts needed to apply the predefined criteria for PPI prescription and to deprescribe PPIs received inappropriately.

Sodium-glucose Cotransporter 2 Inhibitors: The Pleiotropic Mechanisms of Actions.

BACKGROUND: Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are a new class of oral antidiabetic drugs. So far, there are three agents approved for use in Europe and in the USA, two in Japan and another four agents under testing. OBJECTIVE: The purpose of this study is to describe the mechanism of action and the favorable and adverse effects of SGLT-2 inhibitors. METHOD: A thorough review of literature indexed in PubMed, Scopus and Cochrane databases were conducted. Original papers, review papers and their relevant references in English, from 2005 to February 2017, were included. RESULTS: The main mechanism of action is the glycosuria induced by the inhibition of SGLT-2, located in the early segment of the proximal convoluted tubule. Along with large amounts of glucose, sodium, water and uric acid are also excessively excreted in urine. These actions have various, both desired and adverse, consequent implications in kidneys, blood pressure, cardiovascular system and other systems. Moreover, SGLT-2 inhibitors act directly to organs other than the kidneys, as SGLT-2 can be expressed there. CONCLUSION: The underlying mechanisms responsible for the SGLT-2 inhibitor actions, are pleiotropic and occur in the kidneys, as well as in other target organs. The comprehension of these mechanisms, not only permits us to understand their actions better, but it could also help us to predict more of their undisclosed favorable actions, as well as their rare adverse effects.

Diseases Linked to Polypharmacy in Elderly Patients.

INTRODUCTION: Polypharmacy in several cases is deemed necessary and elderly patients are prone to this phenomenon. The objective of this study was to identify the prevalence and the predictors of polypharmacy among consecutively unplanned admissions of patients aged ≥65 years. PATIENTS AND METHODS: In 310 patients (51% women), mean age 80.24 years (95% CI 79.35-81.10), demographic characteristics, medical history, medications, and cause of admission were recorded. Parametric tests and multiple logistic regression analysis were applied to identify the factors that have significant association with polypharmacy. RESULTS: 53.5% of patients belonged to polypharmacy group. In multivariate analysis the independent predictors of polypharmacy were arterial hypertension (p = 0.003, OR = 2.708, and 95% CI 1.400-5.238), coronary artery disease (p = 0.001, OR = 8.274, and 95% CI 3.161-21.656), heart failure (p = 0.030, OR = 4.042, and 95% CI 1.145-14.270), atrial fibrillation (p = 0.031, OR = 2.477, and 95% CI 1.086-5.648), diabetes mellitus (p = 0.010, OR = 2.390, and 95% CI 1.232-4.636), dementia (p = 0.001, OR = 4.637, and 95% CI 1.876-11.464), and COPD (p = 0.022, OR = 3.626, and 95% CI 1.208-10.891). CONCLUSIONS: Polypharmacy mainly was linked to cardiovascular diseases. If deprescribing is not feasible, physicians must oversee those patients in order to recognise early, possible drug reactions.

Neurologic symptoms as the only manifestation of B12 deficiency in a young patient with normal hematocrit, MCV, peripheral blood smear and homocysteine levels.

B12 deficiency is associated with several neurological manifestations. It is well documented that neurologic symptoms due to B12 deficiency may sometimes present in the absence of anemia. However, in most cases there are several indicating factors like megaloblastic changes in complete blood count, hypersegmentated neutrophils or macroovalocytes in peripheral blood smear and abnormal homocysteine levels. In this report, we describe a case of a 32-year-old man with neurological symptomatology as the only manifestation of B12 deficiency with normal hematocrit, mean cell volume, peripheral blood smear and homocysteine levels. All the above emphasize the point that patients with neurologic symptoms must be screened for B12 deficiency even in the absence of any laboratory evidence.

Ulcerative Colitis Activity Presenting as Fever of Unknown Origin, in a Patient with Longstanding Disease under Continuous Treatment with Mesalazine.

Background. The presence of ulcerative colitis (UC) with no bowel symptoms, as fever of unknown origin (FUO), is uncommon. Objective. To describe the case of an 80-year-old woman who presented with fever, with a history of UC under treatment with mesalazine. Case Presentation. She was admitted due to fever lasting for 12 days with no associated symptoms. Seven years earlier, she was diagnosed with UC. After an extended workup for FUO that failed to reach the diagnosis, she underwent a gallium-67 scintigraphy. This revealed a persistent diffuse concentration of gallium-67 in the ascending colon at 24-hour imaging that remained stable at 48- and 72-hour imaging without any topographic change after the use of laxatives. Considering the results and in the absence of another diagnosis, the patient was treated with 30 mg prednisone daily and mesalazine, as treatment of active UC. Subsequently, the patient's condition improved markedly and the fever retreated. One month later, she was reevaluated with a gallium-67 scintigraphy with total absence of gallium-67 concentration in the ascending colon. Conclusion. UC activity must be included in the differential diagnosis of FUO in patients with longstanding disease, since fever may present alone, with no other manifestations.
