Novel diarylated tacrine derivatives: Synthesis, characterization, anticancer, antiepileptic, antibacterial, and antifungal activities.

In this study, our goal was to synthesize novel aryl tacrine derivatives and assess their potential as anticancer, antibacterial agents, and enzyme inhibitors. We adopted a two-step approach, initiating with the synthesis of dibromotacrine derivatives 3 and 4 through the Friedlander reaction. These intermediates underwent further transformation into diarylated tacrine derivatives 3a-e and 4a-e using a Suzuki-Miyaura cross-coupling reaction. Thorough characterization of these novel diarylated tacrines was achieved using various spectroscopic techniques. Our findings highlighted the potent anticancer effects of these innovative compounds across a range of cancer cell lines, including lung, gynecologic, bone, colon, and breast cancers, while demonstrating low cytotoxicity against normal cells. Notably, these compounds surpassed the control drug, 5-Fluorouracil, in terms of antiproliferative activity in numerous cancer cell lines. Moreover, our investigation included an analysis of the inhibitory properties of these novel compounds against various microorganisms and cytosolic carbonic anhydrase enzymes. The results suggest their potential for further exploration as cancer-specific, enzyme inhibitory, and antibacterial therapeutic agents. Notably, four compounds, namely, 5,7-bis(4-(methylthio)phenyl)tacrine (3d), 5,7-bis(4-(trifluoromethoxy)phenyl)tacrine (3e), 2,4-bis(4-(trifluoromethoxy)phenyl)-7,8,9,10-tetrahydro-6H-cyclohepta[b]quinolin-11-amine (4e), and 6,8-dibromotacrine (3), emerged as the most promising candidates for preclinical studies.

A rare case of acute acalculous cholecystitis secondary to hantavirus infection with renal syndrome.

Hantaviruses are single-stranded RNA viruses. They are transmitted to humans by rodents and insectivore hosts. Some Hantavirus subtypes are the causative agents of haemorrhagic fever with renal syndrome (HFRS), which is characterized by fever, thrombocytopenia, and acute kidney injury. Hantavirus infection is difficult to diagnose due to its non-specific clinical symptoms. Causes of acalculous cholecystitis are severe trauma or burn, surgery, long-term starvation and some viral infections. It is very rare for Hantavirus to cause acute acalculous cholecystitis. The treatment of acute acalculous cholecystitis is usually directed towards its symptoms. A 22-year-old male forest worker was admitted to our emergency outpatient clinic with the complaints of fatigue, oliguria, fever, abdominal pain and vomiting. After the clinical and laboratory examinations, HFRS and acute cholecystitis secondary to Hantavirus infection were diagnosed. The patient's condition and clinical findings improved after supportive treatment. Hantavirus infection should be considered in patients with acute kidney injury, cholecystitis and thrombocytopenia (Fig. 2, Ref. 10). Keywords: Hantavirus, acute kidney injury, acalculous cholecystitis, thrombocytopeni.

Comparison of geriatric nutritional risk index and creatinine index in short-term mortality prediction in maintenance hemodialysis patients.

BACKGROUND: The aim of this study is to analyze and compare the predictive values of the Geriatric Nutritional Risk Index (GNRI) and Creatinine Index (CI) in the short-term mortality of maintenance hemodialysis patients and to determine their best cut-offs. METHODS: A total of 169 adult hemodialysis patients were included in this retrospective, cross-sectional, and single-center study. The demographic, clinical, and laboratory data of the month in which the patients were included in the study were obtained from their medical files and computer records. All-cause death was the primary outcome of the study during a 12-month follow-up after baseline GNRI and CI calculations. RESULTS: The mean age of the study population was 57 ± 16 years (49.7% were women, 15% were diabetic). During the one-year observation period, 19 (11.24%) of the cases died (8 CV deaths). The optimal cut-off value for GNRI was determined as 104.2 by ROC analysis [AUC = 0.682 ± 0.06, (95% CI, 0.549-0.815), p = 0.01]. The low GNRI group had a higher risk for all-cause and CV mortality compared to the higher GNRI group (p = 0.02 for both in log-rank test). The optimal sex-specific cut-off was 12.18 mg/kg/day for men [AUC = 0.723 ± 0.07, (95% CI, 0.574-0.875), p = 0.03] and was 12.08 mg/kg/day for females [AUC = 0.649 ± 0.13, (95% CI, 0.384- 0.914), p = 0.01]. Patients with lower sex-specific CI values had higher all-cause and CV mortality (p = 0.001 and p = 0.009 in log-rank test, respectively). In multivariate cox models, both GNRI [HR = 4.904 (% 95 CI, 1.77-13.56), p = 0.002] and sex-specific CI [HR = 5.1 (95% CI, 1.38-18.9), p = 0.01] predicted all-cause mortality. The association of GNRI with CV was lost [HR = 2.6 (CI 95%, 0.54-13.455), p = 0.22], but low CI had a very strong association with CV mortality [HR = 11.48 (CI 95%, 1.25 -104), p = 0.03]. DISCUSSION: In hemodialysis patients, GNRI and CI have similar powers in predicting all-cause short-term mortality. The association of CI with all-cause death depends on gender. On the other hand, sex-specific CI predicts CV mortality better than GNRI.

Recognition and clinical implications of high prevalence of migraine in patients with Brugada syndrome and drug-induced type 1 Brugada pattern.

INTRODUCTION: We have previously reported high 1-year prevalence of migraine in patients with atrial arrhythmias associated with DI-type 1 BrP. The present study was designed to determine the lifetime prevalence of migraine in patients with Brugada syndrome (BrS) or drug-induced type 1 Brugada pattern (DI-type 1 BrP) and control group, to investigate the demographic and clinical characteristics, and to identify clinical variables to predict underlying BrS/DI-type 1 BrP among migraineurs. METHODS AND RESULTS: Lifetime prevalence of migraine and migraine characteristics were compared between probands with BrS/DI-type 1 BrP (n = 257) and control group (n = 370). Lifetime prevalence of migraine was 60.7% in patients with BrS/DI-type 1 BrP and 30.3% in control group (p = 3.6 × 10-14 ). On stepwise regression analysis, familial migraine (odds ratio [OR] of 4.4; 95% confidence interval [CI]: 2.0-9.8; p = 1.3 × 10-4 ), vestibular migraine (OR of 5.4; 95% CI: 1.4-21.0); p = .013), migraine with visual aura (OR of 1.8; 95% CI: 1.0-3.4); p = .04) and younger age-at-onset of migraine (OR of 0.95; 95% CI: 0.93-0.98); p = .004) were predictors of underlying BrS/DI-type 1 BrP among migraineurs. Use of anti-migraine drugs classified as "to be avoided" or "preferably avoided" in patients with BrS and several other anti-migraine drugs with potential cardiac INa /ICa channel blocking properties was present in 25.6% and 26.9% of migraineurs with BrS/DI-type 1 BrP, respectively. CONCLUSION: Migraine comorbidity is common in patients with BrS/DI-type 1 BrP. We identify several clinical variables that point to an underlying type-1 BrP among migraineurs, necessitating cautious use of certain anti-migraine drugs.

Correction to: Blalock-Taussig Shunt Size: Should it be Based on Body Weight or Target Branch Pulmonary Artery Size?

The original version of the article unfortunately contained an alignment error in Table 1. The correct version of Table 1 is given below.

Blalock-Taussig Shunt Size: Should it be Based on Body Weight or Target Branch Pulmonary Artery Size?

The study aimed to revisit the in-hospital predictors of shunt thrombosis (ST) in the foreground of the pulmonary artery size in patients who received modified Blalock-Taussig shunt (mBTS) as the first-stage palliation. Data from 80 patients who received mBTS as their initial palliative procedure between February 2012 and January 2017 was retrospectively collected. The median age and weight of the patients at the time of their mBTS procedure was 4 days (IQR 2-22 days) and 3.2 kg (IQR 2.8-3.7 kg), respectively. Of the 80 patients in the study, 11 (13.8%) developed ST. The diameter and corresponding z scores of the pulmonary arteries were significantly lower in patients with ST. The median shunt size/shunted pulmonary artery size (S/PA) ratio was considerably higher in patients with ST. In logistic regression analysis, pulmonary artery hypoplasia (PAH) [odds ratio (OR) = 13.7 (0.06-0.21), p < 0.001], S/PA ratio ≥ 0.9 [OR = 8.1 (0.03-0.53), p = 0.03], prematurity [OR = 9.5 (0.05-0.33), p = 0.003], and shunt size/weight (S/W) ratio ≥ 1.3 [OR = 6.4 (0.04-0.67), p = 0.012] were found to have a significant impact on ST. The best combination of sensitivity and specificity of the S/W (0.73 and 0.75) and the S/PA ratio (0.73 and 0.80) were achieved at the cut-off value of 1.3 and 0.9, respectively. The Youden index of S/PA was 0.52. While the area under the curve (AUC) of the S/W ratio was 0.686 ± 0.12 (p = 0.049), the AUC of the S/PA ratio was 0.791 ± 0.08 (p = 0.002). In conclusion, instead of weight, considering the size of the target pulmonary artery and thereby, the S/PA ratio would be more instructive in determining shunt size. There were a high number of patients in our study who showed PAH having received a shunt size based on their body weight. By contrast, our results showed that the S/PA ratio of ≥ 0.9 would be a good predictor of in-hospital ST.

Comparison Between Nomograms Used to Define Pediatric Aortic Arch Hypoplasia: Retrospective Evaluation Among Patients Less Than 1 Year Old with Coarctation of the Aorta.

Although various modalities are currently in use to define pediatric aortic arch hypoplasia (AAH), there is little uniformity among them. We aimed to determine the inter-rater strength of agreement of the nomograms in a survey of patients less than 1 year old, who had undergone coarctation of the aorta (CoA) repair with or without AAH. This retrospectively designed study comprised of 105 patients with CoA, who had been evaluated between 2008 and 2018 by means of a computed tomography angiogram. Through re-estimation of the aortic arch segmental diameters, the z scores were calculated using three nomograms (Cantinotti, Pettersen, Lopez). Along with a t test and Pearson's correlation coefficient, a linear regression analysis, Bland-Altman plots, and Cohen's kappa k value were used to evaluate inter-rater strength of agreement. The mean age and weight of the cohort was 73.3 ± 81.2 days and 4.2 ± 1.6 kg, respectively. Sixty-four (61%) patients were neonates. The z scores of the nomograms for each aortic arch segment were significantly different. Although there was a significantly positive correlation between the nomograms with their related aortic arch diameter, the differences in z scores revealed considerable deviations in the scatter plot diagrams. The mean difference of z scores was significantly different from the testing value of zero, which was also presented in Bland-Altman plots. None of the comparisons reached a kappa k value of > 0.9. The current nomograms do not reveal an acceptable level of agreement for the definition of the AAH. The question is which modality to rely on when deciding on the surgical approach and technique of CoA repair to address the hypoplastic aortic arch segment. Decisions about the surgical approach and the technique of repair warrant a reliable definition of AAH. It is high time that a consensus is reached in this regard.

Coexistence of atrioventricular accessory pathways and drug-induced type 1 Brugada pattern.

BACKGROUND: Atrial arrhythmias, particularly atrioventricular nodal reentrant tachycardia, can coexist with drug-induced type 1 Brugada electrocardiogram (ECG) pattern (DI-Type1-BrP). The present study was designed to determine the prevalence of DI-Type1-BrP in patients with atrioventricular accessory pathways (AV-APs) and to investigate the clinical, electrocardiographic, electrophysiologic, and genetic characteristics of these patients. METHODS: One-hundred twenty-four consecutive cases of AV-APs and 84 controls underwent an ajmaline challenge test to unmask DI-Type1-BrP. Genetic screening and analysis was performed in 55 of the cases (19 with and 36 without DI-Type1-BrP). RESULTS: Patients with AV-APs were significantly more likely than controls to have a Type1-BrP unmasked (16.1 vs 4.8%, P = 0.012). At baseline, patients with DI-Type1-BrP had higher prevalence of chest pain, QR/rSr' pattern in V1 and QRS notching/slurring in V2 and aVL during preexcitation, rSr' pattern in V1 -V2 , and QRS notching/slurring in aVL during orthodromic atrioventricular reentrant tachycardia (AVRT) compared to patients without DI-Type1-BrP. Abnormal QRS configuration (QRS notching/slurring and/or fragmentation) in V2 during preexcitation was present in all patients with DI-Type1 BrP. The prevalence of spontaneous preexcited atrial fibrillation (AF) and history of AF were similar (15% vs 18.3%, P = 0.726) in patients with and without DI-Type1-BrP, respectively. The prevalence of mutations in Brugada-susceptibility genes was higher (36.8% vs 8.3%, P = 0.02) in patients with DI-Type1-BrP compared to patients without DI-Type1-BrP. CONCLUSIONS: DI-Type1-BrP is relatively common in patients with AV-APs. We identify 12-lead ECG characteristics during preexcitation and orthodromic AVRT that point to an underlying type1-BrP, portending an increased probability for development of malignant arrhythmias.

Efficacy of golimumab on recurrent uveitis in HLA-B27-positive ankylosing spondylitis.

To evaluate the efficacy of golimumab on severe and frequent recurrent anterior uveitis in patients with HLA-B27-positive ankylosing spondylitis. In this study, 15 eyes of 12 HLA-B27-positive AS patients with resistant anterior uveitis who received 50 mg of subcutaneous golimumab (Gol) per month due to frequent uveitis recurrences were analyzed retrospectively between May 2013 and October 2015. Assessment criteria were uveitis activity, the number of recurrence of uveitis, visual acuity, systemic corticosteroid, or other drug requirement for maintenance of remission of AU. Twelve patients (15 eyes) with HLA-B27-positive ankylosing spondylitis and anterior uveitis have been treated with golimumab 50 mg/month. Remission of uveitis was observed in 12 eyes out of 15. Malign hypertension developed in one subject after the second dose of golimumab therefore the treatment was stopped and this subject was excluded from the study. Median follow-up time was 11 months (interquartile range: 8-18). No uveitic reaction was seen except in the patient who stopped treatment. No topical or systemic steroid necessity was needed except in two cases with oral 4 mg systemic maintenance. Visual acuity was significantly increased (p = 0.002). Golimumab may be a new and effective choice for maintaining remission and the prevention of recurrences of severe, resistant anterior uveitis in patients with HLA-B27-positive ankylosing spondylitis.

The influence of cisplatin, doxorubicin, pegylated doxorubicin, oxaliplatin and gemcitabine on mahlavu cell line.

PURPOSE: Hepatocellar carcinoma (HCC) remains a major health problem being the third leading cause of deaths due to cancer worldwide. Because HCC is known to be highly resistant to conventional systemic therapies, single-agent or combination of systemic therapies have been investigated. Today, sorafenib, a multikinase inhibitor, is the only approved systemic agent for the first line treatment of advanced HCC. In this study, we aimed to investigate the influence of different concentrations of cisplatin, doxorubicin, pegylated doxorubicin (PLD), oxaliplatin and gemcitabine by applying these agents either single or in combinations on mahlavu cell line. METHODS: HCC mahlavu cell line was used for the experiments. Cell death was measured by flow cytometry at 48 hrs after incubation with various concentrations (0.1 µg/ml, 1.0 µg/ml and 10 µg/ml) of the drugs. RESULTS: Cell death due to gemcitabine was found to be significantly higher than cell deaths caused by the other single agents including cisplatin, oxaliplatin, doxorubicin and PLD (p<0.001, p<0.001, p<0.001 and p=0.0049, respectively). There was no significant difference between gemcitabine and both the gemcitabine combination with doxorubicin and PLD (p=0.992 and p=0.441, respectively). CONCLUSION: This is a preliminary analysis evaluating the effect of the conventional chemotherapeutic agents on mahlavu cell line in vitro. The findings of this study suggest that gemcitabine-based therapies keep on being the prefered therapeutic approach for the treatment of HCC.

Evaluation of atrial electromechanical delay and its relationship to inflammation and oxidative stress in patients with chronic obstructive pulmonary disease.

OBJECTIVES: The aims of this study were to evaluate atrial electromechanical delay, inflammation, and oxidative stress parameters, along with to investigate clinical and laboratory characteristics affecting atrial electromechanical delay in patients with chronic obstructive pulmonary disease (COPD). METHODS: Forty-three patients with COPD (60.5 ± 9.9 years) and 50 healthy controls (59.6 ± 7.1 years) were included in the study. Atrial electromechanical delay intervals were measured from lateral mitral annulus corrected PA (cPA lateral) and lateral tricuspid annulus (cPA tricuspid) using tissue Doppler imaging (TDI), and corrected for heart rate. Left and right ventricles functions were examined using conventional and TDI. Plasma levels of high-sensitive C-reactive protein (hsCRP) and oxidative stress parameters were also measured. Factors associated with atrial electromechanical delay were evaluated by stepwise multiple regression analysis. RESULTS: Corrected PA lateral and cPA tricuspid were significantly higher in patients with COPD (69.8 ± 10.4 vs. 62.2 ± 8.9 msec, P < 0.001 and 45.4 ± 10.2 vs. 33.5 ± 5.1 msec, P < 0.001, respectively). Plasma levels of hsCRP and malondialdehyde, an indicator of oxidative stress, were increased in patient's group (15.7 ± 31.7 vs. 4.8 ± 4.7 mg/L, P = 0.01 and 17.1 ± 10.3 vs. 11.6 ± 7.9 nmol/L, P = 0.005, respectively). cPA lateral is independently related to lateral Em /Am ratio (ß = -0.29, P = 0.004) and forced expiratory volume in 1st second/forced vital capacity (FEV1 /FVC) ratio (ß = -0.24, P = 0.02). cPA tricuspid is independently related to only FEV1 /FVC ratio (ß = -0.51, P < 0.001). CONCLUSIONS: This study shows that atrial electromechanical delay intervals are prolonged in patients with COPD. Prolongation of atrial electromechanical delay measured from lateral tricuspid annulus was independently related with FEV1 /FVC ratio in these patients.

Effect of Silica Fume Utilization on Structural Build-Up, Mechanical and Dimensional Stability Performance of Fiber-Reinforced 3D Printable Concrete.

It is known that 3D printable concrete mixtures can be costly because they contain high dosages of binder and that the drying-shrinkage performance may be adversely affected. Mineral additives and fibers are generally used to control these negative aspects. In this study, the use of silica fume, a natural viscosity modifying admixture, was investigated to improve the rheological and thixotropic behavior of 3D printable concrete mixtures reinforced with polypropylene fiber (FR-3DPC). The effect of increasing the silica fume utilization ratio in FR-3DPC on the compressive strength (CS), flexural strength (FS), and drying-shrinkage (DS) performance of the mixtures was also examined. A total of five FR-3DPC mixtures were produced using silica fume at the rate of 3, 6, 9, and 12% of the cement weight, in addition to the control mixture without silica fume. As a result of the tests, the dynamic yield stress value decreased with the addition of 3% silica fume to the control mixture. However, it was found that the dynamic yield stress and apparent viscosity values of the mixtures increased with the addition of 6, 9, and 12% silica fume. With the increase in the use of silica fume, the CS values of the mixtures were generally affected positively, while the FS and DS behavior were affected negatively.

Effect of nano-TiO2 size and utilization ratio on the performance of photocatalytic concretes; self-cleaning, fresh, and hardened state properties.

In this study, photocatalysis technology was used to reduce water pollution. Decolorization of Reactive Black 5 using nano-TiO2 (NT) as a photocatalyst was investigated by adsorption and degradation experiments. Effects of NT particle size and utilization ratio on the time-dependent flow performance, compressive-flexural strength, and Bohme abrasion resistance of cementitious systems were investigated. In addition to the NT-free control mixture, a total of six photocatalytic self-cleaning mortar mixtures (PSCM) were prepared using NT in two different particle sizes (28 and 38 nm) and three different ratios (0.5%, 1%, and 1.5%). The PSCM sample containing 38 nm NT exhibited superior performance in terms of photocatalytic properties compared to the 28 nm state. It was observed that the flow performance of PSCM mixtures with NT substitution is adversely affected regardless of the NT type. Mixtures containing NT with a lower particle size (28 nm) had higher compressive and flexural strengths.

Use of recycled mortar as fine aggregates in pavement concrete applications.

The use of recycled aggregates derived from construction and demolition wastes increased in the concrete construction industry. While the coarse fraction (i.e., from 5 to 20 mm) was successfully recycled, the fine fraction (i.e., from 0 to 5 mm) is hardly recyclable given its heterogenous nature and poor physical properties. This paper assesses the feasibility of recycled mortar aggregate (RMA) in pavement concrete applications requiring superior resistance to weathering and wearing effects. Three concrete strength grade categories prepared with different water-to-binder ratios (w/b) of 0.4, 0.5, and 0.6 are investigated; the natural sand replacement levels by RMA varied from 0 % to 60 % by volume, at 20 % increment rates. Test results showed that the detrimental RMA effect on durability depends on the concrete strength category, requiring proper adjustment of the maximum replacement rate to maintain acceptable losses in performance. Hence, the higher strength grade mixtures prepared with 0.4 w/b were found to yield significant drops in durability reaching 25 % in water sorptivity, 18 % in abrasion, and 22 % due to freeze/thaw (F/T) cycles. In contrast, the lower strength grade concrete made with 0.6 w/b exhibited marginal degradation in strength and durability, despite the incorporation of 60 % RMA. The resulting losses in sorptivity, abrasion, and F/T cycles were limited to 13 %, 8 %, and 12 %, respectively.

Evaluation of endothelial glycocalyx injury biomarkers in feline hemotropic mycoplasmosis.

The present study aimed to investigate endothelial glycocalyx (eGCx) damage in cats with feline hemotropic mycoplasmosis caused by Mycoplasma haemofelis using selected biomarkers and to determine the diagnostic and prognostic significance of these biomarkers. The study included 25 cats with feline hemotropic mycoplasmosis and 10 healthy cats. Clinical examination, blood gas analysis, complete blood count, and biochemical analysis were performed. Hemotropic mycoplasmosis diagnosed by microscopic examination and molecularly confirmed by PCR targeting the Mycoplasma haemofelis 16s rRNA gene. To evaluate endothelial glycocalyx damage, syndecan-1, endothelin-1 (ET-1), asymmetric dimethylarginine (ADMA), and vascular endothelial growth factor-A (VEGF-A) concentrations were measured using cat-specific commercial ELISA kits. Of the cats with feline hemotropic mycoplasmosis, 14 (56%) survived and 11 (44%) died. While syndecan-1 and ET-1 concentrations were significantly higher in cats with hemotropic mycoplasmosis compared to the control group (p < 0.001), no statistically significant difference was found for ADMA and VEGF-A concentrations (p > 0.05). Endothelial glycocalyx biomarkers showed significant correlations with each other and with hematological parameters (p < 0.01). The results of the ROC analysis showed that ET-1 with area under the curve (AUC) of 0.821 (p < 0.01) and VEGF-A with AUC of 0.805 (p < 0.010) were found to be significant prognostic indicators. In conclusion, this study demonstrated that serum syndecan-1 and ET-1 can be used as diagnostic and serum ET-1 and VEGF-A as prognostic biomarkers in cats with hemotropic mycoplasmosis. Our results indicate the development of eGCx damage in feline hemotropic mycoplasmosis and suggest that glycocalyx disruption may contribute to the pathogenesis of the disease.

The relationship between depression, anxiety, quality of life levels, and the chronic kidney disease stage in the autosomal dominant polycystic kidney disease.

PURPOSE: Decreased quality of life, anxiety, depression, and other negative psychosocial factors in autosomal dominant polycystic kidney disease (ADPKD) may lead to the patient's attitudes that reduce treatment effectiveness. We aimed to evaluate the relationship between the depression, anxiety, perceived social support, genetic psychosocial risk and quality of life levels, and chronic kidney disease (CKD) stage in ADPKD and to investigate the relationship between these variables/parameters and the dietary compliance that is an essential factor in the course of the disease. METHODS: 100 ADPKD patients were enrolled in this cross-sectional study. EuroQol-5D-3L (EQ-5D-3L) health-related quality of life index, EuroQol-5D-3L visual analog scale (EQ-5D-3L VAS), multidimensional scale of perceived social support (MSPSS), patient health questionnaire (PHQ)-9, and genetic psychosocial risk instrument (GPRI) were applied to the patients. RESULTS: There is a relationship with negative regression coefficient between the CKD stage and the total scores of the EQ-5D-3L and EQ-5D-3L VAS scales (p < 0.000 and ß = - 5.355, p < 0.000, and ß = - 8.394, respectively). There is a relationship with positive regression coefficient between the CKD stage and MSPSS total score and level (p < 0.000 and ß = 0.364, p < 0.000 and ß = 0.331, respectively). There is no relationship between the CKD stage and GPRI total score (p = 0.800). In addition, there is a relationship with positive regression coefficient between the dietary compliance and EQ-5D and EQ-5D VAS total scores (p = 0.006 and ß = 2.687, p = 0.004 and ß = 3.148, respectively). There is a relationship with negative regression coefficient between the dietary adherence and PHQ-9 total score and CKD stage (p = 0.003, p = 0.006, and ß = - 0.692, respectively). CONCLUSION: As the CKD stage increases in the ADPKD patients, the quality of life decreases, whereas the level of anxiety and depression increases. It has been seen that the ADPKD patients with more depressive complaints have less dietary compliance. In this particular patient group, the early detection and treatment of psychosocial difficulties and the work to improve the quality of life that affect the course of the ADPKD may be as important as the medical treatment. To determine the needs of ADPKD patients with multiple physical and psychosocial difficulties and to perform appropriate interventions, we think that there is a necessity for a specific scale that evaluates these effective components together in the ADPKD process.

De Novo Malignancies After Kidney Transplant: Where Do We Stand and Does the Head and Neck Region Require More Caution?

OBJECTIVES: The aim of this study was to investigate the characteristics of de novo malignancies arising in kidney transplant recipients followed in a tertiary hospital in Turkey and to examine the tumors in the head and neck region as a subgroup. MATERIALS AND METHODS: Data from kidney transplant recipients treated at our institution between January 2010 and July 2022 were retrospectively analyzed in this single-center study. Data regarding malignancies were noted according to the pathologists' reports. In situ malignancies and those arising after graft loss were not evaluated. RESULTS: The study population comprised 231 patients (165 men; 71.4%) with a median follow-up of 11 years (2853 patient-years). The recipients had a higher cancer risk than the general population (standardized incidence rate = 3.04; 95% CI, 1.82-4.26). Thirty de novo malignant tumors were detected in 24 patients (10.4%). The mean age at diagnosis of cancer was 54.88 ± 11.44 years. The median time from transplant to cancer diagnosis was 11.5 years (range, 7-18.8 y). Nonmelanoma skin cancers (56.7% of all tumors) were the most common malignancies. Twenty-two lesions (73.3%) that developed in 17 patients (7.4%) were localized to the head and neck region: 15 (68.2%) were cutaneous and 7 (31.8%) were noncutaneous. The median time from transplant to head and neck cancer diagnosis was 12 years (range, 7.5-17.5 y). Mortality rate was higher in cancer patients (10 [41.7%] vs 17 [8.2%]; P < 0.01). CONCLUSIONS: The incidence of de novo malignancy in kidney transplant recipients was relatively higher compared with previous data. Nonmelanoma skin cancers were the most common type. Three-quarters of all lesions were in the head and neck region, and two-thirds were of cutaneous origin.

Can patient-physician interview skills be implemented with peer simulated patients?

INTRODUCTION: Patient-physician interviewing skills are crucial in health service delivery. It is necessary for effective care and treatment that the physician initiates the interview with the patient, takes anamnesis, collects the required information, and ends the consultation. Different methods are used to improve patient-physician interview skills before encountering actual patients. In the absence of simulated patients, peer simulation is an alternative method for carrying out the training. This study aims to show whether patient-physician interview skills training can be implemented using peer simulation in the absence of the simulated patient. METHODS: This is a descriptive quantitative study. This research was conducted in six stages: identification of the research problem and determination of the research question, development of data collection tools, planning, acting, evaluation, and monitoring. The data were collected via the patient-physician interview videos of the students. The research team performed descriptive analysis on quantitative data and thematic analysis on qualitative data. RESULTS: Fifty students participated in the study. When performing peer-assisted simulation applications in the absence of simulated patients, the success rate in patient-physician interviews and peer-simulated patient roles was over 88%. Although the students were less satisfied with playing the peer-simulated patient role, the satisfaction towards the application was between 77.33% and 98%. DISCUSSION AND CONCLUSION: In patient-physician interviews, the peer-simulated patient method is an effective learning approach. There may be difficulties finding suitable simulated patients, training them, budgeting to cover the costs, planning, organizing the interviews, and solving potential issues during interviews. Our study offers an affordable solution for students to earn patient-physician interview skills in faculties facing difficulties with providing simulated patients for training.

An experience in the COVID-19 pandemic period: Turkish Cardiovascular Surgery Online Board Exam 2020.

Background: The aim of this study was to provide information about the results of the Turkish Cardiovascular Surgery Board written exam, which was held online due to the pandemic. Methods: This cross-sectional study included a total of 41 cardiovascular surgeons and residents (39 males, 2 females) in November 21st, 2020 between 10:00 A.M. and 12:00 P.M. After the online exam was completed, data on participant information and answers to exam questions were obtained from the information system. Results: Of all participants, 39% were working in university hospitals. A total of 82.9% of the participants were specialists. The total mean score of the participants was 60.3±10.2 and 53.7% of them were declared successful-passed. Aortic surgery (63%), heart failure surgery (50%), and mitral valve surgery (50%) were the most incorrectly answered questions. Conclusion: With the online exam, the Board gained different experiences regarding exam planning and implementation. The Turkish Cardiovascular Surgery Board did not give up the Board exam during the pandemic period and conducted a reliable written exam with many participants.

Deviant Behavior of Pedestrians: A Risk Gamble or Just Against Automated Vehicles? How About Social Control?

Recent evidence suggests that the assumed conflict-avoidant programming of autonomous vehicles will incentivize pedestrians to bully them. However, this frequent argument disregards the embedded nature of social interaction. Rule violations are socially sanctioned by different forms of social control, which could moderate the rational incentive to abuse risk-avoidant vehicles. Drawing on a gamified virtual reality (VR) experiment (n = 36) of urban traffic scenarios, we tested how vehicle type, different forms of social control, and monetary benefit of rule violations affect pedestrians' decision to jaywalk. In a second step, we also tested whether differences in those effects exist when controlling for the risk of crashes in conventional vehicles. We find that individuals do indeed jaywalk more frequently when faced with an automated vehicle (AV), and this effect largely depends on the associated risk and not their automated nature. We further show that social control, especially in the form of formal traffic rules and norm enforcement, can reduce jaywalking behavior for any vehicle. Our study sheds light on the interaction dynamics between humans and AVs and how this is influenced by different forms of social control. It also contributes to the small gamification literature in this human-computer interaction.
