RESUMEN
BACKGROUND: Lipoproteins in cell membranes are related to membrane stability and play a role against microorganisms. Patients with COVID-19 often experience myocyte membrane damage. OBJECTIVE: This study aimed to search the relationship of atherogenic indices with myocardial damage and mortality in COVID-19. METHODS: This was an observational, single-center, retrospective study. The study population was grouped according to in-hospital mortality. C-reactive protein (CRP), CRP to albumin ratio (CAR), monocyte to high density lipoprotein cholesterol ratio (MHR), levels of total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDLc), and low-density lipoprotein cholesterol (LDLc) and cardiac troponin I (cTnI) were recorded. Atherogenic indices (plasma atherogenic index [AIP], atherogenic coefficient [AC], Castelli's risk indices I and II [CRI I and II], triglyceride to HDLc ratio (THR) were calculated. RESULTS: A total of 783 patients were included. The mortality rate was 15.45% (n = 121). The median age of non-survivor group (NSG) was higher than survivor group (SG) [66.0 years (Q1 -Q3: 55.0-77.5) vs 54.0 years (Q1 -Q3: 43.0-63.0)] (p < 0.001). Study parameters which were measured significantly higher in the NSG were CRP, cTnI, triglyceride, CRI-I, CRI-II, AC, AIP, ferritin, CAR, MHR and THR. LDLc, HDLc, TC and albumin were significantly lower in NSG (p<0.001). CONCLUSION: THR is positively correlated with myocardial damage and strongly predicts in-hospital mortality in COVID-19.

The short form of the Impulsive Behavior scale (S-UPPS-P) is a widely used scale to measure multiple impulsive personality traits; although it has been translated into many languages, no Turkish translation has been studied to date. Our study had two aims. First, we tested the validity and reliability of the Turkish version of the S-UPPS-P for adolescents. Second, we examined impulsive trait characteristics exhibited by adolescents with ADHD, compared to a community sample. We evaluated the psychometric properties of the Turkish S-UPPS-P scale in 384 adolescents aged 11-18 and tested correlations with ADHD symptoms by assessing 41 adolescents diagnosed with ADHD. Our results showed that with a few slight modifications the Turkish translation of the S-UPPS-P scale can validly assess impulsive trait characteristics for Turkish adolescents. The subscales of lack of premeditation, positive urgency, and negative urgency efficiently distinguished between adolescents with ADHD and control subjects. This is the first scale to evaluate the multidimensional nature of impulsivity in Turkish adolescents. This scale is capable of screening various facets of impulsivity in typically developing adolescents as well as those with ADHD, enabling us to enhance our understanding of possible risks for comorbid diseases in the latter group.

INTRODUCTION: This study aims to prospectively examine patients with ischemic wake-up stroke (WUS) presenting to the emergency department, to investigate the risk factors affecting the mortality occurring within 28, 90, and 180 days, and to create a new scoring system for the prediction of 28-day mortality. MATERIALS AND METHOD: Patients who presented to the emergency department with WUS findings between 01.07.2019 and 30.06.2020 were prospectively analyzed. Logistic regression analysis was performed to determine the factors affecting mortality and the modified Rankin scale (mRS). RESULTS: A total of 161 patients were included. Of the patients, 22.4% died within 28 days and 40.4% within 180 days. The presence of coronary artery disease (CAD) increased the 28-day mortality risk (p = 0.009) 3.57 times, 90-day mortality risk 2.15 times (p = 0.033), and 180-day mortality risk 2.18 times (p = 0.045). In order to be used in the prediction of 28-day mortality in patients with WUS, we developed the ischemic WUS mortality score (IWUSMOS), which consists of the middle cerebral artery (45 points), internal carotid artery (60 points), basilar artery (39 points), superior cerebellar artery (66 points) occlusion, hypertension (33 points), CAD (28 points), malignancy (100 points), and arrhythmia (23 points). With this scoring system, the 28-day mortality risk was determined as 0.05% when the total score was "43" whereas the mortality risk was found to be 95.0% when the total score was "187." CONCLUSION: We propose that IWUSMOS, a new scoring system, can be used to predict the 28-day mortality risk of patients with WUS.

BACKGROUND: This study was designed to investigate the effect of calcineurin inhibitors (CNIs), cyclosporine (CsA), and tacrolimus (Tac) on anthropometrics in kidney transplant recipients. METHODS: 111 of 128 adult kidney transplant recipients who received post-transplant CNIs were included in this retrospective study. Anthropometrics were recorded in the pre-transplant and post-transplant 4-year follow-up periods (1st, 3rd, 6th, 12th, 24th, 36th and 48th months). RESULTS: Compared to pre-transplant values, significant increases in body weight and body mass index (between 3rd and 48th months), waist and hip circumferences (between 1st and 48th months), waist-to-hip ratio (between 1st and 3rd or 6th months) and neck circumference (between 1st and 12th or 24th months) were observed in both CsA and Tac groups. A significant increase was noted in post-transplant body fat percentage values for the 3rd to 24th months in the CsA group, whereas for the 24th to 48th months in both CsA and Tac groups. Hip circumferences percentage changes from the pre-transplant period to the 1st, 12th and 24th months were significantly higher in CsA than in the Tac group. At each time point, there was no significant difference in percentage changes for other anthropometric parameters between the CsA and Tac groups. De novo diabetes mellitus developed in 8.3% of the CsA group and 19.1% of the Tac group. CONCLUSIONS: After a successful kidney transplant, anthropometric measurements increase in most recipients. Although the effect of calcineurin inhibitor type on weight gain is unclear, a regression analysis showed that CNI type was not a risk factor for the development of obesity in the 48th month. However, it is helpful to be cautious about its dyslipidemic effect in patients using CsA and the potential hazards of using Tac in patients with a diabetic predisposition.

BACKGROUND: In the course of SARS-CoV-2 infection, early prognostic evaluation is important since clinical symptoms may worsen rapidly and may be fatal. Inflammation plays an important role in the pathogenesis of COVID-19 and can cause myocardial damage which is common in severe COVID-19 patients. Therefore, novel inflammatory indexes and myocardial damage may be predictive of prognosis in patients with COVID-19. The aim of the study was to evaluate the role of cardiac troponin I (cTnI), modified Glasgow prognostic score (mGPS), systemic immune inflammation index (SII), prognostic nutritional index (PNI), and CRP to albumin ratio (CAR) in the outcome estimation of COVID-19 and to develop a risk model predicting the survival probability of COVID-19 survivors during early post-discharge. METHODS: This was a single-center, observational, retrospective cohort study. Laboratory confirmed COVID-19 patients (n = 265) were included and grouped according to in-hospital mortality. ROC curve analysis was performed and Youden's J index was used to obtain optimal cutoff values for inflammatory indexes in discriminating survivors and non-survivors. Cox regression analysis was performed to assess the possible predictors of in-hospital mortality. A nomogram was constructed based on the Cox regression model, to calculate 7- and 14-day survival. RESULTS: The area under the ROC curve (AUC) of the variables ranged between 0.79 and 0.92 with the three highest AUC values for albumin, PNI, and cTnI (0.919, 0.918, and 0.911, respectively). Optimal threshold value for cTnI was 9.7 pg/mL. Univariate analysis showed that gender, albumin, CRP, CAR, PNI, SII, cTnI, and mGPS were significantly related to in-hospital mortality. The Cox regression analysis indicated that mGPS (p = 0.001), CRP (p = 0.026), and cTnI (p = 0.001) were significant prognostic factors. CONCLUSIONS: cTnI should not be considered merely as an indicator of myocardial damage. It also reflects the inflammatory phase and, along with other inflammatory markers, it should be included in risk models as a prognostic factor for COVID-19.

Background: Magnesium is the second most common cation in the cell. In addition to its role as a cofactor in many enzymatic pathways in physiological processes, it is necessary for the regular functioning of vascular smooth muscle cells. Magnesium deficiency has been associated with exacerbation of inflammation, which plays a role in the aetiopathogenesis of many diseases. Aim: To investigate the potential relationship between serum magnesium level and the development of chronic venous insufficiency by comparison with healthy individuals. Methods: The study included 394 patients with venous insufficiency based on physical examination findings and colour Doppler ultrasonography, and 206 controls without venous insufficiency. Venous insufficiency was defined by colour Doppler as reflux lasting 0.5 seconds or more in superficial veins, and longer than one second in femoral and popliteal veins. Clinical, haematological and biochemical parameters, including serum magnesium level and indicators of inflammation, were compared between groups. Results: A total of 600 participants were included. There was no significant difference between the groups in terms of age and gender. In total, 187 (47.46%) patients with chronic venous insufficiency and 105 (50.97%) of the control group were male (p=0.414). The median age of the patients with chronic venous insufficiency was 48 (min-max: 41-49), and the median age of the control group was 49.00 (min-max: 45.00-60.25) (p=0.064). Serum magnesium level was found to be significantly lower in the group with chronic venous insufficiency compared to the control group; 1.90 mg/dL (min-max: 1.82-2) versus 2.1 mg/dL (min-max: 2-2.2) (p<0.001), respectively. Conclusion: Low serum magnesium levels may pose a potential risk for the development of chronic venous insufficiency, which is common in the community.

INTRODUCTION: We aimed to investigate the clinical, immunological, and genetic factors affecting the response to anti-TNFα (tumor necrosis factor-α) and interleukin-12/23 therapies and drug survivals. METHODS: A total of 180 patients were divided into two groups: 89 patients who used at least two biologic agents, with the initial biologic agent used less than 12 months (group A), and 91 biologic-naive patients who have been receiving a single biologic agent for more than 12 months (group B). ELISA (enzyme-linked immunosorbent assay) was used to analyze anti-drug antibodies (ADAs) in blood samples. Clinical data of the patients were retrospectively analyzed. HLA-SSO (sequence-specific oligonucleotide) Typing Kits were used for HLA-C typing. IBM SPSS v.21 was used for statistical analysis.Results: Infliximab had the longest drug survival as the first biologic agent in group A (p = .015). Etanercept had the lowest ADA count compared to the other anti-TNF agents (p = .001). HLA-Cw6 negativity, late-onset psoriasis, smoking and alcohol use were determined to be risk factors for treatment failure in group A. HLA-Cw6 was found to be associated with type I psoriasis (p = .000). CONCLUSIONS: Although our study is retrospective of a relatively low number of patients, this is a preliminary study focusing on two different patient populations based on therapy response.

BACKGROUND: The aim of this study was to examine whether or not there was a difference in corpus callosum shape between patients with mild to moderate and severe obstructive sleep apnea (OSA) compared with patients who have simple snoring. METHODS: The landmark coordinate data was obtained from the mid-sagittal magnetic resonance imaging (MRI) images of 70 patients who underwent polysomnography. For comparisons, mild and moderate OSA groups were combined and analyses were performed on three groups; simple snoring/control group, mild or moderate OSA group, and severe OSA group. RESULTS: The corpus callosum shape of controls was significantly different from that of the severe OSA group. The most prominent deformities were observed in the genu and rostral body of the corpus callosum for the patients with severe OSA. No significant difference was found between mild/moderate OSA group and simple snoring group in terms of global corpus callosum shape. CONCLUSION: The data demonstrated that severe OSA patients have structural changes in the corpus callosum and deformities may vary as the severity of disease changes.

Abstract Background: In most healthy individuals, blood pressure (BP) shows a circadian rhythm. Being non-dipper increases cardiovascular risk in normotensive and hypertensive individuals. Nocturnal dipping shows a correlation with the state of inflammation. Objetive: To investigate the relationship between inflammation-based indexes and nocturnal BP pattern in normotensive individuals. Method: This is a retrospective study that included patients evaluated with ambulatory BP monitoring (ABPM). A total of 131 normotensive individuals were included and grouped as dippers and non-dippers. The normality of the data was verified with a Shapiro-Wilk test. We compared ABPM variables and inflammation-based indexes derived from blood tests (monocyte to high-density lipoprotein ratio [MHR], platelet to lymphocyte ratio [PLR], neutrophil to lymphocyte ratio [NLR], and systemic immune-inflammation index [SII]) between groups. The independent samples t-test and Mann-Whitney U test were used for comparing variables with normal and non-normal distributions, respectively. The Pearson's chi-squared test was used to compare categorical variables, and Spearman's correlation coefficient was used to examine the relationships between variables. A receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performances of inflammation-based indexes. The level of statistical significance was 5%. Results: The study included 131 patients (mean±standard deviation [SD] age 49.2±15.1 years, 58 [76.0%] of which were women). SII was significantly higher in the non-dipper group (p=0.033). Significant negative correlations were observed between the change in systolic BP [ΔSBP] and SII (r=-0.172, p=0.049) and between ΔSBP and PLR (r=-0.179, p=0.040). Conclusion: SII is a predictor of nocturnal BP pattern in normotensives.
RESUMEN
Magnesium (Mg) is the second most abundant intracellular cation and plays a significant role in immune system and cardiac protection. Mg deficiency contributes to chronic low-grade inflammation leading to cardiovascular diseases, and low Mg level exacerbates virus-induced inflammation. The aim of the study was to investigate whether serum magnesium level is associated with myocardial damage and prognosis of COVID-19. This was a single-center, observational retrospective study of patients with COVID-19. The study population was divided into two groups according to in-hospital mortality: a survivor group (SG) and a non-survivor group (NSG). Myocardial damage was defined as blood levels of cardiac troponin I (cTnI) above the 99th percentile upper reference limit. Magnesium, variables regarding inflammation, and myocardial damage were compared between the groups. A total of 629 patients with COVID-19 were included. Mortality rate was 11.85% (n = 82). There were 61 (74.4%) and 294 male patients (53.7%) in NSG and SG, respectively (p = 0.001). The median age of NSG was 64.5 years (min-max: 37-93) and the median age of SG was 56.0 years (min-max: 22-92) (p < 0.001). Median serum magnesium levels of NSG and SG were 1.94 mg/dL (min-max: 1.04-2.87) and 2.03 mg/dL (min-max: 1.18-2.88), respectively (p = 0.027). Median cTnI levels of NSG and SG were 25.20 pg/mL (min-max: 2.10-2240.80) and 4.50 pg/mL (min-max: 0.50-984.3), respectively (p < 0.001). The cTnI levels were lower in those patients whose serum Mg levels were higher than 1.94. Although serum magnesium level was not a predictor for in-hospital mortality, there was a significant negative correlation between magnesemia and myocardial damage.

OBJECTIVE: To investigate the shape differences in the putamen of early-onset Parkinson's patients compared with healthy controls and to assess and to assess sub-regional brain abnormalities. METHODS: This study was conducted using the 3-T MRI scans of 23 early-onset Parkinson's patients and age and gender matched control subjects. Landmark coordinate data obtained and Procrustes analysis was used to compare mean shapes. The relationships between the centroid sizes of the left and right putamen, and the durations of disease examined using growth curve models. RESULTS: While there was a significant difference between the right putamen shape of control and patient groups, there was not found a significant difference in terms of left putamen. Sub-regional analyses showed that for the right putamen, the most prominent deformations were localized in the middle-posterior putamen and minimal deformations were seen in the anterior putamen. CONCLUSION: Although they were not as pronounced as those in the right putamen, the deformations in the left putamen mimic the deformations in the right putamen which are found mainly in the middle-posterior putamen and at a lesser extend in the anterior putamen.

Increased risk of pancreatic cancer may be associated with consumption of sugar containing foods. The aim of this study was to evaluate the effect of peach nectar containing high fructose corn sirup (HFCS) consumption in a pancreatic carcinogenesis rat model induced by 7,12-Dimethyl benzanthracene (DMBA). Fifty-day-old male Sprague Dawley rats were fed with peach nectar containing HFCS + chow, peach nectar containing sucrose + chow and only chow. After 8 mo, feeding period, each group was divided into two subgroups, in which the rats were implanted with DMBA and no DMBA (sham). Histologic specimens were evaluated according to the routine tissue processing protocol. The animals with ad libitum access to pn-HFCS, pn-sucrose and chow (only) showed significant differences in chow consumption and glucose level. Necropsy and histopathologic findings showed tumor formation in the entire group treated with DMBA. Excluding one rat in chow group, which was classified as poorly differentiated type, the others were classified as moderately differentiated pancreatic ductal adenocarcinoma (PDAC). This study demonstrated that daily intake of HFCS did not increase body weight and there was no effect of peach nectar consumption on the development of PDAC induced by DMBA in rats.

OBJECTIVES: We investigate the relationship between the severity of vascular disease and epicardial adipose tissue thickness(EAT-t) and the neutrophil/lymphocyte (NEU/LY) ratio in acute stroke patients. METHODS: Seventy-six patients and 38 healthy controls were included in the study. Strokes were divided into three groups: lacunar infarction, middle cerebral artery infarction (MCA), and other arterial infarcts. Patients were assessed using the GCS (Glasgow coma scale) and NIHSS (National Institutes of Health Stroke Scale) scales. In addition to laboratory measurements, EAT-t was evaluated in all patients by using echocardiography. RESULTS: The EAT-t value and NEU/LY ratio were higher in the patient group than in the control group. The MCA group was found to have a significantly higher NEU/LY ratio than the lacuna group (pâ¯=â¯0.017) as well as the other patient (pâ¯=â¯0.025) group. There was a positive correlation of NIHSS score with EAT-t (râ¯=â¯0.291; pâ¯=â¯0.013), and NEU/LY ratio (râ¯=â¯0.289; pâ¯=â¯0.014). CONCLUSION: The EAT-t and NEU/LY ratio were high in patients with acute ischemic stroke patients. The higher ratio of NEU/LY compared to other infarcts in the MCA group. These findings support the relationship between acute ischemic stroke severity and inflammation .

Purpose: Osteoporosis is a systemic skeletal disease with a consequent increase in fractures rates. Osteoporosis may be primary which is related with normal aging, or secondary which occurs in the presence of an underlying disease or medication. Osteoporosis is one of the significant comorbidities in chronic obstructive pulmonary disease (COPD). In this study, we aimed to investigate the presence of osteoporosis and the influencing factors in COPD patients. Patients and Methods: This is a two-group comparison study that was conducted among 30 COPD patients on inhaled corticosteroid (ICS) and 33 controls. It was conducted in the outpatient clinics at the Departments of Physical Medicine and Rehabilitation and Pulmonary Diseases in Bursa Uludag University Hospital, a tertiary reference center, in the northwest region of Turkey. For both groups, demographic variables, osteoporosis risk questioning, body mass index (BMI), bone mineral density (BMD), biochemical blood tests, vertebral fractures on lumbar and thoracic x-rays were recorded. COPD patients were also evaluated for lung functions via spirometry. Results: Thirty patients with COPD (Group 1) and 33 controls (Group 2) were included in the study. Comparing the demographic and biochemical data, no difference was found between the groups except smoking (pack/year) (p<0.001) and erythrocyte sedimentation rate (p<0.001), which were significantly high in COPD group. BMD in the COPD group was significantly lower in both hip and lumbar regions compared with the controls. There were significant correlations between L2 BMD values and pulmonary function tests. BMI was significantly low in osteoporotic COPD patients when compared with the non-osteoporotic COPD patients (p=0.002). Conclusion: In patients with COPD using inhaled corticosteroids, BMD was significantly low compared with the controls. Osteoporotic COPD patients had significantly lower BMI than non-osteoporotic. These findings suggest that pulmonary dysfunction and low BMI are associated with osteoporosis in COPD patients.

INTRODUCTION: Olfactory impairment and cognitive impairment are common non-motor symptoms in Parkinson's disease (PD). Olfactory impairment may be present even many years before the main symptoms of the disease develop. The associations between olfactory loss and cognition in PD are evaluated in this study. METHODS: 31 patients with PD and 31 healthy subjects were included in this study. The Unified Parkinson's Disease Rating Scale (UPDRS) and Hoehn and Yahr Scale (H&Y Scale) were administered to all subjects. Butanol threshold test and Sniffin'Sticks test were used to assess olfaction. The Mini Mental State Examination (MMSE) and Clock Drawing Test (CDT) and Stroop Color Word Test (SCWT) were used to assess cognition. RESULTS: The Sniffin'Sticks test scores were significantly lower in the Parkinson group in comparison to the control group (p<0.001). The rate of anosmia was 90% in the PD group while this rate was found to be 54.8% in control group (p=0.005). A significant correlation was found between butanol test scores and stoop 5 and 5 errors. Significant correlations were found between the Sniffin'Sticks scores and MMSE scores (p=0.047) and orientation (p=0.041) and language (p=0.003) functions of the MMSE test. Worse olfaction was associated with worse memory. CONCLUSIONS: In PD, olfactory impairment correlates with cognitive impairment and olfactory tests may be used to predict the likelihood of developing dementia in this patient population.
RESUMEN
OBJECTIVES: In this study we aimed to investigate corpus callosum shape differences between restless leg syndrome patients and healthy controls, and to determine whether disease severity and duration are indicators for corpus callosum deformation in RLS patients. METHODS: This study was conducted using the magnetic resonance imaging scans of 33 restless leg syndrome patients and 33 control subjects. Landmarks were marked on the digital images and callosal landmark coordinate data were used to assess shape difference by performing Generalized Procrustes analysis. The shape deformation from controls to the patients was evaluated performing the Thin Plate Spline approach. RESULTS: There was a statistically significant shape difference between the groups. Highest deformation was determined at the posterior midbody of the corpus callosum. Growth curve analyses showed that with the increase in disease duration and severity, the CC size decreased. DISCUSSION: The present study demonstrated callosal shape differences in restless leg syndrome using a landmark-based geometric morphometric approach, considering the topographic distribution of corpus callosum for the first time.

Aim: To investigate the association of food addiction (FA) with the psychosocial functioning and metabolic parameters in obese patients seeking weight-loss treatment. Methods: Two hundred twenty-four obese patients (male/female: 28/196) with a mean age of 44.5 ± 13.4 years and body mass index (BMI) of 41.6 ± 7.2 were included in the study. After receiving sociodemographic data and medical history, detailed physical examination, including anthropometric measurements, was performed by an experienced physician. Blood samples were taken after 8-12 hr of fasting. The presence of FA was evaluated by using Yale Food Addiction Scale (YFAS). Psychological evaluation was performed by using a self-reported Patient Health Questionnaire-9 (PHQ-9) and health-related quality of life using the 36-item short-form health survey (SF-36). Results: Seventy-two of 224 (32.1%) patients met the criteria for FA, according to YFAS. The mean age of patients with FA was younger compared with patients without FA (P < 0.001). There was no statistically significant difference between the patients with and without FA in terms of BMI, fat percentage, and waist circumference (P = 0.440, P = 0.644, and P = 0.144, respectively). The depression frequency was significantly higher (61.1%, P < 0.001), while the SF-36 score of mental health was lower (P = 0.027) in patients with FA than in the patients without FA. Age- and sex-adjusted mean fasting plasma glucose level was lower in patients with FA (P = 0.021), but serum insulin levels, HOMA-IR (homeostasis model assessment of insulin resistance), HbA1c (hemoglobin A1c), lipid parameters, and vascular adiposity index were comparable. Conclusions: We found that FA frequency was very high in obese patients seeking treatment for weight loss, and it correlates with psychosocial functioning more than metabolic parameters.

Purpose: To investigate the olfaction and taste functions in obese female patients and the association between serum ghrelin and leptin levels compared with healthy controls. Methods: Fifty-two obese women, who have a body mass index >30 kg/m2, and 15 healthy women were included in the study. After 8 hrs fasting, blood samples were taken for serum biochemical parameters, ghrelin, and leptin level measurement. For the quantitative assessment of olfactory function, all participants underwent an N-butanol threshold test and odor identification test using 12 Sniffin' Sticks® fragrance sticks. The gustatory function was tested by administering a whole-mouth above threshold test using sucrose solutions. Results: The sucrose taste threshold score in obese women was significantly higher than the controls (P = 0.004). We found positively significant correlation between serum ghrelin levels and n-butanol threshold scores in obese women (r = 0.300, P = 0.031). N-butanol smell threshold was not significantly different between the two groups (P = 0.149), while the Sniffin' Sticks smell test scores were significantly lower in obese women compared with the controls (P = 0.007). Serum leptin levels were also significantly higher in obese women (P < 0.001) although there was no significant difference in serum ghrelin levels between the two groups (P = 0.768). There was no correlation between serum leptin levels and Sniffin' Sticks scores, n-butanol, and sucrose taste threshold scores in obese women. Conclusions: These results might suggest that leptin, which is an anorexigenic peptide, may have a negative effect on taste and smell functions. More studies are warranted to elucidate the exact role of ghrelin secretion on olfaction and taste functions.

BACKGROUND: Parkinson's disease is a neurodegenerative disease. Cognitive disorders and retinal degeneration may occur during the early stages of the disease. Retinal degeneration and cognitive findings can be assessed easily with optical coherence tomography and mini-mental test, respectively. MATERIALS AND METHODS: Twenty-two patients who are being followed-up with Parkinson's disease and 22 healthy controls have been included in the study. The Unified Parkinson's Disease Rating Scale (UPDRS) and Hoehn-Yahr staging of the patients have been conducted at the time of admission. Retinal nerve fiber layer analysis and ganglion cell thickness (ganglion cell complexes [GCCs]) were evaluated through optical coherence tomography (OCT). And at the same time, we aimed to compare the stage of the disease, the UPDRS score and the duration of the disease with OCT and cognitive functions by mini-mental test. RESULTS: Mini-mental test total score value (P = 0.025) and language value (P = 0.021) were lower in the patient group compared to the control group. In patients, there is a reverse significant correlation between UPDRS-T and GCC-left-superior (r = -0.495; P = 0.026), GCC-left-inferior (r = -0.517; P = 0.019), and GCC-left-to (r = -0.508; P = 0.022). There is a significant parallel relation between recall and RFNL-right-mean (r = 0.626; P = 0.039). CONCLUSION: Our findings indicate that the neurodegeneration continues multisystemically and neurodegeneration increases simultaneously with the disease. OCT, which is a noninvasive method, can be used as an indicator of neurodegeneration in patients with Parkinson's disease.
RESUMEN
BACKGROUND: We investigated the effect of short-term telmisartan usage in addition to lifestyle changes such as diet and exercise on insulin resistance, lipid metabolism, and serum adiponectin and tumor necrosis factor-alpha (TNF-α) levels in hypertensive patients with metabolic syndrome (MetS). METHODS: A total of 36 hypertensive patients with MetS were randomized to telmisartan and control groups in an open-labeled prospective study. RESULTS: There were significant decreases in anthropometric variables of patients according to baseline measurements in both groups at the end of the study. Serum insulin level and insulin resistance assessed by homeostasis model assessment-insulin resistance were decreased significantly in the telmisartan group (P = 0.040 and P = 0.034, respectively) compared with the controls, while there was no statistically significant change in the lipid profiles of the two groups. Serum adiponectin level was increased by 19.1% ± 41.7% in the telmisartan group, but intergroup analysis revealed no significant change. There was also no significant change in serum TNF-α level in either group. CONCLUSION: It has been observed that even short-term telmisartan treatment had favorable effects on insulin resistance and glucose metabolism compared with lifestyle changes alone. The fundamental effect of telmisartan treatment on insulin resistance renders it a good therapeutic option for hypertensive patients with MetS.
