    ABSTRACT OBJECTIVE: The aim of this study was to evaluate the sociodemographic and clinical chracteristics of patients hospitalized with aspiration pneumonia in internal medicine clinics, and to determine the incidence and parameters of mortality among these patients. METHODS: Patients over the age of 18 years who were hospitalized in clinics of internal medicine between January 1, 2010 and January 1, 2013 (115 male, 89 female; mean age: 77±13 years; patients aged 65 years and over, 88.2%; average duration of hospitalization, 11±9 days) were evaluated retrospectively and consecutively. The incidence of mortality, nutritional status at admission, comorbidity frequency, haematological and biochemical data and their relationship with mortality were evaluated. RESULTS: At admission, 85% of the patients were fed through oral route, while 15% of them were fed through PEG. There was no relation between nutritional status of the patients (oral, nasogastric tube or PEG) at admission, and development of aspiration pneumonia. Commonly seen comorbidities were dementia (49%), hypertension (43%), cerebrovascular accident (42%), and diabetes mellitus (31%) respectively. The mortality rate was 24.5% (in first three days, 56%). A correlation was found between mortality and increase in neutrophil/lymphocyte ratio (NLR) and increased uric acid rate (for both p<0.05). CONCLUSION: In this study, the mortality rates among patients diagnosed with aspiration pneumonia was found to be increased. The high number of geriatric patients and comorbidities might have played a role in this situation. Neutrophil/lymphocyte ratio (NLR) and uric acid levels in patients with aspiration pneumonia might be evaluated as factors related to mortality

    Introduction of a novel quantitative scoring system for acanthosis nigricans and its validation in a pilot study

    Inconsistent data exist regarding the diagnostic value of acanthosis nigricans (AN) or skin tags as clinical markers for obesity or diabetes. In an outpatient department-based prospective study, we designed a scoring for AN severity (SCANS) to evaluate AN and skin tags, their correlation with obesity or diabetes. Quantification of AN in six anatomic sites, in consideration of the affected skin surface areas, texture changes, number of skin tags, leads to a total severity score between 0 and 46. Among 336 adult patients (aged >= 18 years) with AN, a higher BMI was associated with AN (r = 0.299, P < .001), but not with diabetes (P = .43), as compared with 243 age- and sex-matched controls without AN. Among nondiabetics, AN scores were significantly correlated with waist circumference (r = 0.131, P = .024) and total cholesterol levels (r = 0.155, P = .04). Skin tags alone in the absence of AN were not associated with obesity (P = .333) or diabetes (P = .164). The total AN scores were positively correlated with the presence of skin tags (r = 0.132, P < .001), and the involvement of anterior neck (r = 0.668, P < .001) and axilla (r = 0.793, P < .001). Knuckles and groins were unaffected in our series. Our results indicate that combination of AN with skin tags can be used as clinical marker for obesity, but not for diabetes. Large-scale studies on patients of different ethnic background are required to further validate our proposed scoring.WOS:0005867211000012-s2.0-85096708449PubMed: 3310333

    Effects of Allopurinol on Endothehial Dysfunction: A Meta-Analysis

    No full text
    Objective: Several studies have assessed the effect of allopurinol on endothelial function, but these studies were relatively small in size and used different methods of evaluating endothelial function. We conducted a meta-analysis to investigate the effect of allopurinol on both endothelial-dependent and -independent vasodilatation

    Endocan: a novel predictor of endothelial dysfunction in obstructive sleep apnea syndrome

    No full text
    Background and Aims: Obstructive sleep apnea syndrome (OSA) is an independent risk factor for endothelial dysfunction and cardiometabolic diseases. Plasma endocan levels are elevated in a large number of diseases, and is a novel surrogate endothelial cell dysfunction marker. We aimed to assess the role of serum endocan level as a potential mechanism of endothelial dysfunction in OSA patients

    Endothelial dysfunction in patients with acromegaly and It & rsquo;s association with Endocan

    Objective: This study aims to assess endocan levels in patients with acromegaly who have active disease or disease in remission and to investigate a relation between endocan levels and endothelial dysfunction in these patients. Design: The study is a case-control study. Study was conducted at Istanbul Medeniyet University Goztepe Training and Research Hospital between 2013 and 2019. Patients who were older than 18 years with acromegaly diagnosis were recruited if they agreed to participate. Patients with uncontrolled diabetes (DM), hypertension (HT), hyperlipidemia, decompensated heart failure, immune or infectious diseases, moderate-severe valve disease and stage 3 or more advanced chronic kidney disease were excluded. There were 30 healthy control subjects who agreed to participate to the study. Patients with acromegaly were divided into two groups as: disease active patients and patients in remission. Serum endocan levels were measured with enzyme linked immunosorbent assay (ELISA) method endothelial function was assessed with flow mediated dilatation (FMD). Results: There were 85 patients included to the study. Twenty-three patients had active disease, 31 were in remission and 31 were healthy controls. FMD was higher in controls compared to patients in active disease and patients in remission (p < 0.001). There was no difference between patients with active disease for FMD and patients in remission (p = 0.088). There was statistically significant correlation between FMD and endocan and insulin like growth hormone-1 (IGF-1) levels of patients with acromegaly. As FMD increased endocan and IGF-1 decreased. A moderate negative relation between FMD and endocan was identified (p < 0.001, r:-0.409) as well as FMD and IGF-1 levels (p:0.011, r:-0.377). Along with endocan and IGF-1, DM, HT, sex, body mass index, age and uric acid were associated with changes in FMD. Conclusions: Endocan levels and endothelial function measured with FMD have an inverse relationship. Endocan may prove to be a marker for endothelial dysfunction in acromegaly

    A Potential Treatment of Non-Alcoholic Fatty Liver Disease with SIRT1 Activators

    No full text
    Sirtuins (SIRTs) are members of the silent information regulator-2 family and act as nicotinamide adenine dinucleotide (NAD+)-dependent histone/protein deacetylases. The de-acetylation of proteins and histones results in an up- or down-regulation of gene transcription and protein function. In recent years, the regulatory action of the deacetylation activity of SIRT1 has been shown to have a positive impact on the pathophysiological mechanisms of nonalcoholic fatty liver disease (NAFLD). Among the effects of SIRT1 are: its healing activity on insulin sensitivity, thereby ameliorating glycemic regulation; its mimetic activity on calorie restriction; its antihyperlipidemic activity on lipid homeostasis via the liver, adipose tissues and skeletal muscles; its anti-inflammatory activities; its protective effects against cardiovascular events and endothelial dysfunction; its positive influence on autophagy, apoptosis and cancer; and finally, its anti-aging activity. The current approach for the treatment of NAFLD involves the treatment of etiological factors and recommendation of life-style changes including more physical activity and a low-calorie diet. However, there is no specific medical treatments for NAFLD. The therapeutic potential of SIRT1 activity in the treatment of NAFLD discovered in humans has been presented in this article. In this review, the potential effects of SIRT1 activation on NAFLD-related pathophysiological mechanisms and on the treatment of NAFLD are discussed
