Short-Term Effect of Conventional Versus Accelerated Corneal Cross-Linking Protocol on Corneal Geography and Stability.

Purpose: To determine the 6-month effect of conventional (CXL30) and accelerated cross-linking with a UVA intensity of 9 mW/cm2 (CXL10) on corneal stability and to investigate whether there was a difference in ABCD grading system parameters regarding the two different procedures. Methods: Twenty-eight eyes of 28 patients with a documented keratoconus (KN) progression were included. Patients were selected to undergo either epi off CXL30 or CXL10. At the baseline and the follow-up visits after one (V1), three (V2), and six months (V3), the patients underwent complete ophthalmic examination and corneal tomography. Results: In the CXL30 group, all the parameters from the ABCD grading system significantly changed from baseline to V3; parameter A decreased (p = 0.048), B and C increased (p = 0.010, p < 0.001), and D decreased (p < 0.001). In the CXL10 group, there were no changes in parameters A (p = 0.247) and B (p = 0.933), though parameter C increased (p = 0.001) and D decreased (p < 0.001). After an initial decline after one month, visual acuity (VA) recovered on V2 and V3 (p < 0.001), and median maximal keratometry (Kmax) decreased in both groups (p = 0.001, p = 0.035). In the CXL30 group, there were significant changes in other parameters; average pachymetric progression index (p < 0.001), Ambrósio relational thickness maximum (ARTmax) (p = 0.008), front and back mean keratometry (p < 0.001), pachymetry apex (PA) (p < 0.001), and front elevation (p = 0.042). However, in the CXL10 group, there were significant changes only in ARTmax (p = 0.019) and PA (p < 0.001). Conclusion: Both epi-off CXL protocols showed similar short-term efficacy in improving VA and Kmax, halting the progression of KN, and both similarly changed tomographic parameters. However, the conventional protocol modified the cornea more significantly.

Analysis of Influencer Marketing in the Positioning Healthy Eating According to Generation Z in Croatia.

BACKGROUND: The eating habits of Generation Z have changed a lot compared to other Generations. It is presumed that influencers significantly influence the choice of diet among Generation Z. This study aimed to investigate Generation Z's opinion about social networks and the influence of communication channels, mostly influencers, on the choice of diet. SUBJECTS AND METHODS: This study included 178 participants born between 1997-2010. It was conducted using the Google forms questionnaire program. Participants were initially asked demographic questions such as age, gender, and physical activity. These were followed by questions about their eating habits, social networks, and influencers. After the survey, the results were analyzed using TIBCO Statistica™ 14.0.0. RESULTS: Out of 178 participants, 59% were female, and 41% were male. Most respondents (60.6%) declared that they eat healthily, and among several options to choose from, most respondents chose options related to a healthy diet. Respondents who care about healthy food often seek information from influencers on social networks. Respondents who declared that they eat healthy most often believe that influencers are a credible source of information (p=0.019) and follow influencers for motivation (p=0.022) and for the information they share (p=0.009). Respondents who declared that they pay attention to calorie intake more often believe that influencers are a credible source of information (p=0.011). CONCLUSION: The results of this study suggest that influencers greatly influence the eating habits of Generation Z and that they are aware of healthy eating habits. Also, those who take care of healthy eating, follow influencers.

BLOOD PRESSURE IS ASSOCIATED WITH DIABETIC RETINOPATHY IN TYPE 1 BUT NOT IN TYPE 2 DIABETES.

The aim of this study was to investigate the role of systolic blood pressure (SBP) and diastolic blood pressure (DBP) in the development of diabetic retinopathy (DR) in type 1 and type 2 diabetes and to determine the differences between these two types of diabetes. This cross-sectional study included 84 patients with type 1 diabetes (T1DM) and 107 patients with type 2 diabetes (T2DM). Ophthalmologic retinal examination included indirect slit-lamp fundoscopy, color fundus photography according to EURODIAB (EUROpe and DIABetes) protocol and optical coherence tomography. Blood pressure was measured with a mercury sphygmomanometer after a 10-minute rest period. In T1DM, DR was positively associated with SBP (p = 0.035), HbA1cmedian (p < 0.001) and hypertensive retinopathy (p < 0.001), while in T2DM DR was positively related only to HbA1cmedian (p = 0.021). Binary logistic regression analysis (no DR/DR) showed that diabetes duration and HbA1cmedian were the main predictors of DR in both types of diabetes. In contrast, SBP (OR = 1.05, p = 0.045) and hypertensive retinopathy (OR = 3.75, p < 0.001) were the main predictors/indicators of DR only in T1DM. In conclusion, blood pressure is associated with DR in type 1 but not in type 2 diabetes.

Systemic inflammation and dyslipidemia are associated with retinopathy in type 2 but not in type 1 diabetes.

The aim of this study was to investigate risk factors and role of systemic inflammation, dyslipidemia and obesity in development of diabetic retinopathy (DR) in type 1 and type 2 diabetes and determine the differences in risk factors between these two types of diabetes. Eighty-four type 1 and 107 type 2 diabetic patients were included in this cross-sectional study. Diabetes duration, body mass index (BMI) and waist-to-hip ratio (WHR) were assessed. C-reactive protein (CRP), fibrinogen (FIB), glycated hemoglobin (HbA1c), fasting and postprandial blood glucose (fBG, ppBG), HDL and LDL cholesterol and triglycerides (TG) were determined using routine methods. HbA1cmedian was obtained by statistical analysis of the CroDiabNet data and used as a marker of long-term glycemic control. Albumin excretion rate (AER) was measured in a 24-hour urine collection. Ophthalmologic retinal examination included indirect slit-lamp fundoscopy, color fundus photography according to EURODIAB (EUROpe and DIABetes) protocol and optical coherence tomography. DR was positively related to diabetes duration (p < .001), HbA1cmedian (p < .001) and AER (p = .008) in type 1, and diabetes duration (p < .001), HbA1cmedian (p = .018), AER (p < .001), CRP (p = .048) and TG (p = .041) in type 2 diabetes. Regression analysis showed that diabetes duration (OR 1.20, p = .005) and HbA1cmedian (OR 6.92, p = .007) were the main predictors of DR in type 1, and diabetes duration (OR 1.17, p < .001), fBG (OR 1.45, p = .024) and TG (OR 2.08, p = .025) in type 2 diabetes. In conclusion, systemic inflammation and dyslipidemia are associated with DR in type 2 but not in type 1 diabetes.

Serum bilirubin levels are negatively associated with diabetic retinopathy in patients with type 1 diabetes and normal renal function.

INTRODUCTION: Previous studies suggested that total serum bilirubin levels are negatively associated with diabetic retinopathy (DR) and nephropathy in patients with diabetes mellitus. The objective of this study was to explore the relationship between serum total bilirubin levels and prevalence of DR in patients with type 1 diabetes (T1DM) and normal renal function. METHODS: Study included 163 T1DM with normal renal function (urinary albumin excretion rate <30 mg/24 h, estimated glomerular filtration rate (eGFR) >60 ml min-11.73 m-2). Photo-documented retinopathy status was made according to the EURODIAB protocol. RESULTS: Patients with DR were older (49 vs 42 years, p = 0.001), had higher systolic blood pressure (130 vs 120 mmHg, p = 0.001), triglycerides (0.89 vs 0.77 mmol/L, p = 0.01), and lower serum total bilirubin (12 vs 15 U/L, p = 0.02) and eGFR (100 vs 106 ml min-11.73 m-2, p = 0.03). In multivariate logistic regression analysis, only total serum bilirubin was significantly associated with risk of DR in our subjects (OR 0.88, CI 0.81-0.96, p = 0.006). CONCLUSION: These data suggest that serum total bilirubin levels are independently negatively associated with DR in T1DM with normal renal function. Prospective studies are needed to confirm whether lower serum total bilirubin has predictive value for the development of DR in T1DM with normal renal function.

The Use of Anthropometric Measurements of Obesity in Prediction of Microvascular Complications in Obese Type 2 Diabetic Patients.

Waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) are superior to body mass index (BMI) in predicting type 2 diabetes mellitus (T2DM) development. The aim of this study was to investigate the predictive power of BMI, WC, WHR and WHtR for microvascular (chronic kidney disease (CKD), retinopathy and peripheral neuropathy) prevalence in obese (BMI ≥35 kg/m2) T2DM patients. This cross-sectional study included 125 T2DM patients of both genders. The validity of each test was assessed by Receiver Operating Characteristic (ROC) curves; the area under the curve (AUC) was calculated for each anthropometric parameter and microvascular complication. AUCs for WHtR were significantly higher than AUCs for WC with respect to CKD. Optimal cut-off for WHtR was >0.593 and WC >112 cm regarding CKD. The AUC for peripheral neuropathy was significant only for WHR and optimal cut-off for WHR was >1.409 with low sensitivity and high specificity. Our study demonstrated that WHtR, WC and WHR might be used as simple and noninvasive methods for detection of CKD and peripheral neuropathy in obese T2DM population.

Waist-to-height ratio is independently associated with chronic kidney disease in overweight type 2 diabetic patients.

OBJECTIVE: Chronic kidney disease (CKD) is one of the most serious complications in obesity-induced type 2 diabetes mellitus (T2DM). Body mass index (BMI), waist-to-hip ratio (WHR), waist circumference (WC) and waist-to-height ratio (WHtR) are recognised as sensitive obesity measures. We aimed to investigate the association of BMI, WC, WHR and WHtR with CKD prevalence in overweight T2DM patients. DESIGN, SUBJECTS AND METHODS: We obtained 125 overweight T2DM patients coming for their in-patient annual visit. Metabolic profiles and anthropometric indices were measured and calculated. Urine albumin excretion (UAE) was determined as the mean of 24-h urine from two consecutive days. Serum creatinine was measured from fasting blood sample in order to calculate the estimated glomerular filtration rate (eGFR) using the Chronic Kidney Disease Epidemiology Collaboration formula. Patients were divided into two groups according to CKD prevalence. RESULTS: Thirty-six (28.8%) patients met diagnostic criteria for CKD. The WHtR and WC were higher in the group with CKD. WHtR correlated positively with UAE (r = 0.828, p < 0.001) and negatively with eGFR (r = -0.262, p = 0.015). No significant correlation was observed with WC in relation to UAE (p = 0.335) nor eGFR (p = 0.121). WHtR yielded the significant and great OR in association with nephropathy after adjustment for all confounding risk factors. CONCLUSION: WHtR might be of a greater importance in association to CKD compared to other anthropometric parameters that indicate central obesity. Whether it is a best measure of central obesity and its exact role in CKD pathology is yet to be investigated.

Alkaline phosphatase is independently associated with renal function in normoalbuminuric type 1 diabetic patients.

Nonalcoholic fatty liver disease (NAFLD) is associated with an increased prevalence of chronic kidney disease in patients with type 1 diabetes. The aim of this study was to explore the relationship between markers of NAFLD, namely concentrations of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALK), γ-glutamyltransferase (GGT), bilirubin, and renal function in type 1 diabetic patients. This study included 313 normoalbuminuric type 1 diabetic patients with estimated glomerular filtration rate (eGFR) >60 mL/min/1.73 m(2), without clinical evidence of cirrhosis or other causes of chronic liver disease and before any interventions with statins, angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers. ALT, GGT, and bilirubin levels were significantly higher in subjects in the highest quartile of serum creatinine compared to those in lowest quartile (21 vs. 20 U/L, 18 vs. 14 U/L, and 14 vs. 10 µmol/L, respectively, for all p < 0.05). ALK levels were significantly higher in subjects in the highest quartile of urinary albumin excretion rate compared to those in lowest quartile (71 vs. 69 U/L, p = 0.03), as well as in hyperfiltrating subjects compared to those with normal or mildly impaired eGFR (81 vs. 68 and 64 U/L, p < 0.001). In a multiple logistic regression model adjusted for age, sex, duration of diabetes, HbA1c, and body mass index (BMI), only ALK levels were significantly associated with disturbances in serum creatinine and eGFR in our subjects (p ≤ 0.007), with odds ratios of 0.98-1.02. NAFLD associated markers, particularly ALK, are associated with renal function in normoalbuminuric type 1 diabetic patients.

[Pathophysiological factors in the development of diabetic nephropathy--new insights]. / Patofizioloski cimbenici razvoja dijabeticke nefropatije--nove spoznaje.

Diabetic nephropathy (DN), also known as Kimmelstiel-Wilson syndrome, is a progressive kidney disease characterized by nephrotic syndrome and diffuse glomerulosclerosis. It affects about 30% of patients with diabetes mellitus and is a prime indication for dialysis in many Western countries as well as in Croatia. Moreover, it takes a high fourth place in total disease cost, thus it is a very important public health problem. Hyperglycemia, dyslipidemia and hypertension are well established risk factors for the disease development and progression. However, nowadays, the knowledge about the pathophysiology of the disease is expanded and recently focused on the role of growth factors. Well balanced local and plasma concentration of growth factors is important for achievement and maintenance of glomerular integrity and function, so any disturbances could be a contributing factor to the development of DN. There is a growing body of literature suggesting that bone morphogenic protein 7 (BMP7), fibroblast growth factor 23 (FGF23) and fibroblast growth factor 21(FGF21) may play an important role in the DN development and progression. BMP7 possesses antifibrotic and proteolytic activity, so it could diminish the action of profibrotic factors and play an inhibitory role in the disease pathogenesis. It has been demonstrated that plasma concentration of BMP7 is decreasing in parallel to the drop in glomerular filtration rate (GFR) and albumin excretion increase. The plasma concentration of FGF21 and FGF23 has been shown to increase in parallel to DN progression. Moreover, they are linked with hyperinsulinemia and insulin resistance as well as with other diabetic complications such as cardiovascular events and endothelial dysfunction and retinopathy conditions closely related to DN. However, the background of the disturbances is not well established; it is not clarified whether GFR lowering causes increase of FGF21 and FGF23 or the increase in FGF21 and FGF23 concentration causes GFR lowering. The loop is yet to be clarified in order to develop a possible novel therapeutic approach in the treatment of this disease with serious consequences for the individual as well as for the entire population.

[Importance of standardized stepwise screening in patients with resistant hypertension]. / Vaznost sistemskog probira u algoritmu dijagnostike rezistentne hipertenzije.

Resistant hypertension (RH) is a condition that confers a high cardiovascular risk to the patient due to both persistent blood pressure elevation and the high prevalence of comorbidities and organ damage. Hypertension is defined as resistant (RH) to treatment when a therapeutic strategy that includes appropriate lifestyle measures plus a diuretic and two other antihypertensive drugs belonging to different classes at adequate doses fails to lower blood pressure (BP) values to < 140 and 90 mm Hg, respectively. Prior to diagnosing a patient as having RH, it is important to document adherence and exclude white-coat hypertension, inaccurate measurement of BP, and secondary causes. Ambulatory BP monitoring (ABPM) has become an important tool in the diagnosis and follow-up of hypertensive patient, and it is even more important in the evaluation of those with resistant RH. Among patients with RH, it is very important to select patients with standardized stepwise screening: ABPM of resistant hypertensives has a circadian profile with a high proportion of nondipping. The possible reasons for the absence of dipping are sleep disturbance, obstructive sleep apnea, obesity, high salt intake in salt-sensitive subjects, orthostatic hypotension, autonomic dysfunction, chronic kidney disease, diabetic neuropathy, and old age. It seems reasonable to routinely use ABPM in the initial evaluation of all resistant hypertensive patients. In a significant number of these patients, ABPM will also be an essential tool in follow-up, especially regarding the possible effects of all therapeutic maneuvers that are devoted to bringing BP into the target ranges. The potential success of other therapeutic options such as renal denervation depends on the ability to select patients most likely to benefit.

Patients with Type 2 Diabetes, Higher Blood Pressure, and Infrequent Fundus Examinations Have a Higher Risk of Sight-Threatening Retinopathy.

Background: Diabetic retinopathy (DR) is the most common cause of preventable blindness among working-age adults. This study aimed to evaluate the impact of the regularity of fundus examinations and risk factor control in patients with type 2 diabetes (T2DM) on the prevalence and severity of DR. Methods: One hundred and fifty-six T2DM patients were included in this cross-sectional study. Results: In this sample, the prevalence of DR was 46.2%. Patients with no DR mainly did not examine the fundus regularly, while most patients with mild/moderate nonproliferative DR (NPDR) underwent a fundus examination regularly. In 39.7% of patients, this was the first fundus examination due to diabetes, and 67% of them had sight-threatening DR (STDR). Diabetes duration (p = 0.007), poor glycemic control (HbA1c) (p = 0.006), higher systolic blood pressure (SBP) (p < 0.001), and diastolic blood pressure (DBP) (p = 0.002) were the main predictors of DR. However, the impact of SBP (AOR 1.07, p = 0.003) and DBP (AOR 1.13, p = 0.005) on DR development remained significant even after adjustment for diabetes duration and HbA1c. The DR prevalence was higher in patients with higher blood pressure (≥130/80 mmHg) than in those with target blood pressure (<130/80 mmHg) (p = 0.043). None of the patients with target blood pressure had STDR. The peaks in SBP and DBP were observed in T2DM with DR and the first fundus examination due to diabetes. Conclusions: In this T2DM sample, DR prevalence was very high and strongly related to blood pressure and a lack of regular fundus examinations. These results indicate the necessity of establishing systematic DR screening in routine diabetes care and targeting blood pressure levels according to T2DM guidelines.

Corneal Biomechanics and Other Factors Associated with Postoperative Astigmatism after Cataract Surgery.

This study aimed to investigate the impact of the cornea's biomechanical properties, corneal hysteresis (CH), and corneal resistance factor (CRF) on postoperative astigmatism after cataract surgery and determine the other factors that influence it. Forty eyes of 40 patients (13M/27F; the median age of 74) were included in this prospective study, underwent 2.75 mm incision cataract surgery, and were followed for 30 days. Visits were scheduled at baseline before surgery (V0), the 1st (V1), the 7th (V2), and the 30th (V3) postoperative days. The main parameters estimated and analyzed with Statistica® 14.0.1 were CH, CRF, astigmatism diopter, and axis. Following the cataract surgery, the CH did not significantly change during the study visits (p = 0.109). However, there was a significant change in the CRF from baseline during the study visits (per protocol set) (p = 0.002). After a slight but insignificant increase from V0 to V1, post hoc analysis found a significant decrease in the mean CRF from V1 to V2 (p = 0.049) with no substantial change from V2 to V3. According to the post hoc analysis, the median astigmatism diopter increased significantly only from V0 to V1 (p = 0.001) and slightly but not significantly decreased to the end of the study with the achievement of a near-baseline value. The main predictors for the final astigmatism diopter (R2 = 0.898) obtained by stepwise regression analysis were its values at V0, V1, and V2 (p < 0.001). The CRF at V1 was marginally significant, with a negative parameter estimate of -0.098303 (p = 0.0623). In conclusion, there was no correlation between preoperative CH and CRF and postoperative astigmatism using 2.75 mm incision cataract surgery. However, the final astigmatism diopter's main predictors were its baseline values before cataract surgery, the first, and the seventh postoperative days.

Risk Factors for Ankle Brachial Index and Carotid Artery Stenosis in Patients with Type 2 Diabetes.

Type 2 diabetes mellitus (T2DM) significantly increases the risk of atherosclerotic cardiovascular disease. Ankle brachial index (ABI) and carotid artery stenosis are non-invasive indicators of generalized atherosclerosis. This study aimed to explore the risk factors for ABI and carotid artery stenosis and discover which factors simultaneously influence both conditions in T2DM. The study included a total of 101 patients with T2DM. ABI was performed via Doppler ultrasound, and both common carotid arteries were examined via ultrasound to obtain the percentage of carotid artery stenosis. A negative correlation was noted between the ABI and the percentage of carotid artery stenosis (p = 0.043). ABI correlated significantly negatively with waist circumference (p = 0.031), total cholesterol (p = 0.003), low-density lipoprotein (LDL) cholesterol (p = 0.003), and C-reactive protein (CRP) (p = 0.017), whereas the percentage of carotid artery stenosis correlated with the smoking habit (p = 0.017) and CRP (p = 0.042). The best model for predicting the ABI value (R2 = 0.195) obtained from stepwise regression analysis included waist circumference, LDL cholesterol, triglycerides, and CRP, while the best model for the percentage of the carotid artery stenosis (R2 = 0.112) included smoking and CRP. CRP influenced the ABI value with a negative parameter estimate of -0.008962 (p = 0.053) and the percentage of the carotid artery stenosis with a positive parameter estimate of 0.443655 (p = 0.006) relative to a one-unit change of it, presenting the negatively significant impact of CRP on the association between carotid artery stenosis and low ABI. Our results suggest that CRP is the most important risk factor that connects ABI and carotid artery stenosis, which are important non-invasive indicators of generalized atherosclerosis in T2DM.

In Association with Other Risk Factors, Smoking Is the Main Predictor for Lower Transcutaneous Oxygen Pressure in Type 2 Diabetes.

Type 2 diabetes mellitus (T2DM) significantly increases the risk of peripheral artery disease (PAD), and diabetes is the leading cause of nontraumatic amputations. This study investigated the risk factors for transcutaneous oxygen pressure (TcPO2) in T2DM, a noninvasive method to quantify skin oxygenation and the underlying microvascular circulation. The study included 119 T2DM patients (91 male/28 female). TcPO2 measurements were conducted with the Tina TCM4 Series transcutaneous monitor (Radiometer, Copenhagen, Sweden) and skin electrodes. Patients with TcPO2 < 40 mmHg were younger (p = 0.001), had significantly higher systolic blood pressure (SBP) (p = 0.023), glycated hemoglobin (HbA1c) (p = 0.013), fasting plasma glucose (fPG) (p = 0.038), total cholesterol (p = 0.006), LDL cholesterol (p = 0.004), and had more frequent smoking habits (p = 0.001) than those with TcPO2 ≥ 40 mmHg. The main predictors for the TcPO2 value (R2 = 0.211) obtained via stepwise regression analysis were age, smoking, SBP, HbA1c, fPG, and total and LDL cholesterol. Among all the listed predictors, smoking, HbA1c, and LDL cholesterol were found to be the most significant, with negative parameter estimates of -3.051310 (p = 0.0007), -2.032018 (p = 0.0003), and -2.560353 (p = 0.0046). The results of our study suggest that in association with other risk factors, smoking is the main predictor for lower TcPO2 in T2DM.

Post-Blink Blur Time-A Simple Test to Detect Dry Eye-Related Visual Disturbances.

Background: Dry eye disease (DED) stands out as one of the most common eye conditions encountered in clinical settings. This study aimed to determine the diagnostic ability and feasibility of post-blink blur time (PBBT) in detecting patients with DED symptoms. Methods: The study included 200 subjects, 100 with and 100 without DED symptoms defined by the Schein questionnaire, who underwent assessment of DED signs [visual acuity, PBBT, conjunctival hyperemia, lid-parallel conjunctival folds-LIPCOF, tear film break-up time-TBUT, fluorescein corneal staining, and meibum score]. Results: DED subjects had a lower PBBT than controls (p < 0.001), with subjective (6 (1-45) s vs. 8 (1-70) s) and objective (6 (2-33) s vs. 8 (2-50) s) PBBT measurements being similar between repeats. The correlations between subjective and objective PBBT measurements were significantly positive (R = 0.873, p < 0.001). Subjective PBBT was negatively related to the Schein questionnaire (R = -0.217, p = 0.002), conjunctival hyperemia (R = -0.105, p = 0.035), and corneal staining (R = -0.153, p = 0.031), while positively related to the TBUT (R = 0.382, p < 0.001) and meibum score (R = 0.106, p = 0.033). Logistic regression analysis showed DED symptoms were significantly associated with subjective PBBT (AOR 0.91, p = 0.001), TBUT (AOR 0.79, p < 0.001), meibum score (AOR 0.65, p = 0.008), LIPCOF (AOR 1.18, p = 0.002) and corneal staining (AOR 1.14, p = 0.028). Conclusions: Subjective self-reported PBBT is a reliable and non-invasive screening test for evaluating time-wise changes in visual acuity and detecting a tear film dysfunction.

Comparison of vitamin K and non-vitamin K oral anticoagulants and the bleeding frequency in the emergency department.

INTRODUCTION: Safety studies of anticoagulant therapy have so far been conducted on many subjects in controlled conditions (i.e., clinically monitored) and demonstrated the noninferiority of new ones over old anticoagulant drugs. Data on the propositions for the presence of symptoms and signs of bleeding among various anticoagulants in the emergency department indicate that these data do not match the data published so far. AIM: The aim of the study was to investigate the differences in the frequency of bleeding and bleeding-related symptoms as a reason for emergency department attendance in patients on anticoagulant therapy. METHODS: The study included patients from the emergency department of University Hospital for one year, who were on anticoagulant therapy and who met the inclusion criteria. Out of a total of 595 patients, 409 were on warfarin (68.74%), and the rest were taking direct oral anticoagulants (DOAC): dabigatran 71 (11.93%), rivaroxaban 66 (11.09%) and apixaban 49 (8.23%). RESULTS: Out of 409 patients taking warfarin, 34.4% were adequately anticoagulated with the frequency of bleeding 13.7%, while in 57.2% of patients, PT INR was higher than the reference values with the frequency of bleeding 15.0%. A comparison between all DOAC groups and adequately anticoagulated warfarin patients in the frequency of bleeding and bleeding-related symptoms as a reason for emergency attendance yielded a difference that was marginally statistically significant (Pearson Chi-Square = 7.554, p = 0.052). CONCLUSION: Monitoring the frequency of bleeding and bleeding-related symptoms in patients on oral anticoagulant therapy as a reason for emergency department attendance may be a new safety and efficacy factor in real-life patient scenarios.

Personality dimensions and treatment adherence among glaucoma patients: the role of self-transcendence.

BACKGROUND: Cloninger's psychobiosocial model of personality proposes that consistent patterns of health behavior are determined by the complex interaction of different neurobiological processes of the patient's temperament and character dimensions. Poor medication adherence is a pervasive problem among glaucoma patients and can lead to increased morbidity and disability. The objective of the present study was to investigate the association between Cloninger's personality dimensions and medication adherence among glaucoma patients. METHODS: The cross-sectional study was conducted among 113 primary open-angle glaucoma (POAG) patients. The treatment adherence was assessed through a valid and reliable self-administered questionnaire, the Culig Adherence Scale (CAS). Personality dimensions were evaluated using the abbreviated version of the Temperament and Character Inventory-Revised (TCI-140). Statistical analyses were performed using TIBCO Statistica 14.0.1. The study protocol was registered in the DRKS - German Clinical Trials Register; (DRKS-ID: DRKS00022081). RESULTS: According to CAS, only 39.8% of patients were adherent to glaucoma treatment. Adherence was significantly negatively related only to the character dimension of Self-Transcendence (p < 0.05). No other TCI-140 dimension was significantly associated with medication adherence (p > 0.05). CONCLUSIONS: The results suggest that POAG patients with higher scores on the Self-Transcendent personality dimension are more likely to experience difficulties adhering to medication regimen. The study highlights the importance of a holistic approach to glaucoma treatment, which takes into account not only the biological aspects of disease but also the psychosocial factors that influence patient behavior. Healthcare providers may need to consider glaucoma patients' personality dimensions, beliefs and values when developing treatment plans and strategies to improve medication adherence.

Hyperfiltration in normoalbuminuric type 1 diabetic patients: relationship with urinary albumin excretion rate.

Hyperfiltration has been documented in type 1 diabetes and may contribute to the high risk for development of albuminuria and progression of nephropathy. However, recent studies suggest that the risk of progression to albuminuria in type 1 diabetes was not increased by hyperfiltration. We investigated associations of estimated glomerular filtration rate (eGFR) and urinary albumin excretion rate (UAE) in normoalbuminuric type 1 diabetic patients. Study included 313 normoalbuminuric patients with type 1 diabetes, none showed signs of adrenal, renal, or cardiovascular diseases. GFR was estimated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. Glomerular hyperfiltration was defined as eGFR > or = 125 mL min(-1) 1.73 m(-2). Renal hyperfiltration was present in 12% of the study group. Subjects with eGFR > or = 125 mL min(-1) 1.73 m(-2) were younger, had shorter duration of diabetes, lower levels of total and LDL cholesterol, and higher HbA1c than subjects with an eGFR below 125 mL min(-1) 1.73 m(-2). Type 1 diabetic patients with hyperfiltration also had significantly lower UAE. In a multiple logistic regression analysis, higher eGFR was associated with lower UAE. Our results indicate that normoalbuminuric type 1 diabetic patients with hyperfiltration have lower UAE than those with renal function in the normal range. Together with other recent studies this may suggest that creatinine-based estimates of GFR indicating hyperfiltration is not associated with higher UAE and subsequent development of microalbuminuria.

Total and LDL cholesterol are associated with glomerular filtration rate in normoalbuminuric type 1 diabetic patients.

Studies have generally suggested a positive association between dyslipidemia and chronic kidney disease, but sparse data are available on the relation of lipids and glomerular filtration rate in patients with normal renal function. We investigated the associations of serum lipids, including total, LDL, HDL, VLDL cholesterol, and triglyceride levels with estimated glomerular filtration rate (eGFR) in type 1 diabetic patients. Study included 313 normoalbuminuric type 1 diabetic patients with normal or mild decrease (eGFR > 60 mL/min per 1.73 m2) renal function and before any interventions with statins, ACE inhibitors or angiotensin II receptor blockers. eGFR was significantly associated with total, LDL, and HDL cholesterol (r = -0.21, -0.18, and -0.17, respectively, for all p < 0.05). Stratifying serum lipids for degree of eGFR, levels of total, LDL, and HDL cholesterol were inversely related to eGFR, but trends were significant only for total (5.1 vs 5.0 and 4.6 mmol/L) and LDL cholesterol (2.9 vs 2.8 and 2.4 mmol/L). We have detected an association between eGFR and lipid abnormalities in type 1 diabetes in early stages. The study was conducted in patients with no therapeutic intervention. This may suggest that lipid abnormalities may play a role in the pathogenesis of renal impairment in type 1 diabetic patients.

Association between red blood cell count and renal function exist in type 1 diabetic patients in the absence of nephropathy.

Anemia is a prevalent finding in patients with type 1 diabetes, particularly in those with albuminuria or reduced renal function. We investigated the relationship between red blood cell count (RBC) and renal function in type 1 diabetic patients with normal or mildly impaired renal function and urinary albumin excretion rate (UAE) < 30 mg/24 h. Study included 313 type 1 diabetic patients with estimated glomerular filtration rate (eGFR) > 60 mL min(-1) 1.73 m(-2), and before any interventions with statins, ACE inhibitors or angiotensin II receptor blockers. UAE was measured from at least two 24-h urine samples. Hemoglobin (Hb), hematocrit (Hct), erythrocytes (E), serum iron and ferritin levels were significantly lower in subjects in the highest quartile of serum creatinine compared to those in lowest quartile (132 vs 148 g/L, 0.39 vs 0.42 L/L, 4.5 vs 4.8 x 10(12)/L, 13 vs 18 micromol/L, and 25 vs 103 microg/L, respectively, for all p < 0.001). Hb and Hct levels were significantly lower in subjects in the highest quartile of UAE compared to those in lowest quartile (135 vs 140 g/L, and 0.40 vs 0.41 L/L, respectively, for all p = 0.03). Finally, those with mildly impaired eGFR had significantly lower levels of Hb, Hct and E compared to those with normal eGFR or hyperfiltrating subjects (133 vs 140 g/L, 0.38 vs 0.41 L/L, and 4.4 vs 4.7 x 10(12)/L, respectively, for all p = 0.01). We have detected that interplay between RBC and renal function parameters occurs even in type 1 diabetic patients with normal or mildly impaired renal function.
