Abstract
OBJECTIVE Endovascular aortic repair (EVAR) for elective and emergency infrarenal aortic pathologies is the primary approach for treatment nowadays. During such procedure, the suture-mediated closure device (SMCD) (Perclose ProGlideTM, Abbott Laboratories, Chicago, IL, USA) is commonly used. This study aimed to identify potential contributors for SMCD failure in a patient cohort of elective and emergency EVAR. METHODS Archived medical records from patients who underwent EVAR for aortic pathologies in elective and emergency setting at the University Hospital Düsseldorf, Germany were included. Patient's co-morbidities, access vessel morphologies and hemostasis-related blood parameters were evaluated on their association with SMCD failure applying different statistical methods. RESULTS A total of 71 patients (139 femoral accesses) was included. The mean age was 73.5 ± 8.4 years. Overall SMCD failure rate was 4.3%, 4.1% for elective and 5.9% for emergency cases, respectively. Total procedure time was longer for the SMCD failure group (323 ± 117.8 min vs 171 ± 43.7 min). The calcification status of the common femoral artery (CFA), the diameter of the aortic bifurcation, and dual anti-platelet therapy (DAPT) on the medication plan prior to the procedure were associated with SMCD failure. Univariate binary logistic regression analysis nominated several potentially relevant predictors for SMCD failure who underwent subsequent multivariable binary logistic regression analysis. Here, DAPT on the medication plan was identified as being promising in predicting SMCD failure (OR 30.5), while anterior plaque formation in the CFA maintained as only statistically relevant determinant (OR 44.9). CONCLUSIONS This study confirms the CFA calcification status to be associated with SMCD failure. Although discontinued prior to endovascular treatment, DAPT was also found to be associated with SMCD failure. Our results may advocate to perform obligatory platelet testing prior to EVAR to maximize patient safety.

Abstract
PURPOSE The goal of this paper was to compare the intraocular pressure (IOP) measurements obtained via iCare Pro rebound (IRT), non-contact tonometry (NCT), and Goldmann applanation (GAT) tonometry in healthy subjects. MATERIALS AND METHODS One hundred and twenty-five healthy individuals were included in this study. The participants' IOP measurements were obtained via non-contact tonometry. After routine ophthalmic examination, central corneal thickness (CCT) was measured with a topography device. Intraocular pressure was measured via iCare Pro rebound tonometry. After waiting for 5minutes, three measurements were taken with GAT under topical anaesthesia, and their means were recorded. Interdevice agreement was evaluated with the intraclass correlation coefficient (ICC) and Bland-Altman analysis. RESULTS The mean IOP measurements for NCT, IRT, and GAT were 15.97±2.99, 17.47±2.86, and 16.46±2.68mmHg, respectively. The mean difference between NCT and GAT was -0.49± 1.89mmHg, the mean difference between IRT and GAT was 1.01±1.90mmHg, and the mean difference between NCT and IRT was -1.50±2.02mmHg. Agreement between devices was found to be >0.8 for each tonometry ICC. There were significant positive correlations between the measurements obtained via these three instruments and CCT. CONCLUSION In this study, IOP was measured slightly lower with NCT than GAT, but it was about 1mmHg higher with IRT than GAT on average. All three devices appeared to be affected by CCT, with NCT being the most affected in this regard. The three instruments can be used for routine inspection and screening. However, considering the differences in the measurements obtained by using them, it is clear that following up IOP measurements with GAT measurements is beneficial in advanced glaucoma patients.

Abstract
OBJECTIVE The aim of this retrospective cohort study was to investigate complete blood count parameters in patients with Behçet's disease (BD) who present with oral ulcers and patients with recurrent aphthous stomatitis (RAS) in order to determine whether they could be used as discriminatory biomarkers. PATIENTS AND METHODS This study was conducted between January 2019 and January 2023. The study population consisted of three groups: patients with BD who had oral ulcer manifestation (n=85, BD-Group), patients with idiopathic RAS (n=186, RAS-Group) and healthy controls (n=90, HC-Group). All data about participants, on their first application, including sociodemographic and clinical data, comorbidity status, laboratory results were collected retrospectively from the hospital computer records and patients' charts. RESULTS The groups were similar in terms of age (p=0.235) and sex distribution (p=0.450). Mean platelet volume (MPV) and plateletcrit values of the BD-Group were significantly lower, while platelet distribution width (PDW) was significantly higher, compared to the other two groups (p<0.001 for all). Low MPV (<9.15) (56.47% sensitivity and 90.86% specificity), high PDW (≥15.75) (75.00% sensitivity and 94.96% specificity) and low plateletcrit (<0.237) (55.29% sensitivity and 79.46% specificity) could significantly distinguish BD patients with oral ulcer onset from patients with RAS. CONCLUSIONS PDW, MPV, and plateletcrit may be useful biomarkers in the differential diagnosis of oral ulcers when distinguishing between BD and RAS. However, these results need to be supported by further comprehensive studies.

Abstract
PURPOSE The purpose of this study was to compare central corneal thickness (CCT) values and evaluate the agreement obtained with three different devices in healthy eyes. METHODS A total of 120 eyes of 60 healthy individuals (36 men and 24 women) were enrolled in this retrospective study. CCT measurements were performed using an optical biometer (AL-Scan), spectral-domain optical coherence tomography (SD-OCT) (Topcon 3D) and ultrasonic pachymetry (UP) (Accupach VI), and the results were compared. Bland-Altman analysis was used to quantify the agreement between methods. MAIN RESULTS The mean patient age was 28±5.73years (18-40years). The mean CCT values obtained by AL-Scan, UP, and SD-OCT were 532.4μm±29.7, 549μm±30.4, and 547μm±30.6, respectively. The mean differences in CCT were 15.30±9.52μm between AL-Scan and OCT (P<0.01), 17.15±8.42μm between AL-Scan and UP (P<0.01), and 1.85± 8.78μm between UP and OCT (P=0.067). All three methods of CCT measurement were closely correlated with each other. CONCLUSION The present study results suggest that, despite good agreement between the three devices, AL-Scan significantly underestimated CCT compared to UP and OCT. Therefore, clinicians should be aware that different results can be obtained using different devices for CCT measurements. It would be a better approach not to use them as interchangeable in clinical practice. CCT examination and follow-up should be performed using the same device, especially for patients who will undergo refractive surgery.

Abstract
Background Although spinal anesthesia can be applied in different patient positions, the most frequently used positions are sitting and lateral positions. It is known that different patient positions during spinal anesthesia have effects on hemodynamic parameters, postdural puncture headache, and intraocular pressure. Aim The study aimed to determine the effect of spinal anesthesia performed in either sitting or right lateral position on postspinal headache and intraocular pressure during elective cesarean section. Patients and Methods The study was a randomized controlled study of 104 eligible pregnant women scheduled to undergo elective cesarean section. The women were randomized into two groups. Spinal anesthesia was performed either in the sitting (Group S, n = 53) or the right lateral position (Group L, n = 51). Heart rate and blood pressure were recorded throughout the operation. The participants were informed and monitored for postspinal headaches. Intraocular pressure before and after the operation was measured with Icare PRO. The obtained data were statistically compared between the two groups. Results There was no difference between the groups in terms of demographic data. Postdural puncture headache was observed in five patients in Group S and one patient in Group L (P =0.04). There was no difference between the groups in terms of intraocular pressure (P >.05). Heart rate was not significantly different between the groups; however, there was a significant difference in average blood pressure in 1, 5, 30, and 40 minutes (P <.05). The number of trials administered to patients for spinal anesthesia was significantly higher in Group L (P =0.01). Conclusion Spinal anesthesia performed in the sitting position for cesarean section caused a higher postspinal headache than in the right lateral position, but the position did not affect intraocular pressure.

Abstract
BACKGROUND The C-reactive protein (CRP)/albumin ratio (CAR) is one of the new tools to assess the severity of inflammation. It is used to determine clinical severity and prognosis in many diseases. AIM The present study aimed to investigate the relationship between C-reactive protein (CRP)/albumin ratio (CAR) and prognosis in pregnant patients with more severe COVID-19 infection. Retrospective study. PATIENTS AND METHODS The study was conducted in a retrospective manner by scanning the files of pregnant patients who had a positive polymerase chain reaction test result and were hospitalized in Adıyaman Training and Research Hospital. The patients were divided into two groups: patients who were admitted to the intensive care unit and patients who were not admitted. CRP/albumin ratio (CAR) levels were compared between these two groups. The cut-off value was determined in the prediction of intensive-care admission and poor prognosis. RESULTS 117 patient files were reviewed. 13 patients were followed up with intensive care, whereas 104 patients completed their treatment in the service. The CAR levels of the patients admitted to intensive care were significantly higher (P < 0.01). In the estimation of intensive-care admission, the CAR level was determined to be 0.970 in the area under the curve with 100% sensitivity and 86.5% specificity in the receiver operating characteristic (ROC) curve. The cut-off CAR level was calculated as 1.8. CONCLUSION CAR is a valuable biomarker for predicting prognosis, as well as follow-ups of pregnant COVID-19 patients.

Abstract
Abstract
Study question
Do DUCs significantly impact embryo development? In particular, morphokinetics, grading, and Pre-implantation Genetic Testing for Aneuploidy (PGT-A) outcome? Is this analysis corroborated by artificial intelligence?
Summary answer
DUC embryos develop slower, have lower rates of blastulation and lower CHLOE (Fairtility) scores for blastulation and implantation. However, occasionally euploid blastocysts form from DUCs.
What is known already
Time-lapse technology enables the identification of DUCs during embryo development. Previous research associates DUCs with poorer blastulation, implantation, and ploidy outcomes. However, DUCs are not routinely annotated in all clinics. Some algorithms, deselect embryos with short second cell cycles; hence, DUCs are rarely transferred. Whether DUC embryos should be automatically discarded or deprioritised is an ongoing debate which leads to inconsistency in clinical practices across fertility centres. AI image processing algorithms may assist embryologists in the identification of DUCs.
Study design, size, duration
A retrospective single-centre study of normally-fertilised embryos cultured in time-lapse incubators throughout 2019--2021. We reviewed 9284 time-lapse videos using an AI image processing tool (CHLOE, Fairtility), and assessed DUC embryo outcomes (ploidy, blastulation, and blastocyst quality). Additionally, we analysed pronuclei data searching for possible causes of DUCs.
Participants/materials, setting, methods
CHLOE (Fairtility) software analysed time-lapse videos identifying pronuclei, DUCs, and blastulation; recording all morphokinetic time points (tPNa,tPNf,t2,t3,t4,t5,t6,t7,t8,t9,tM, tSB,tB,tEB), morphological grades for the inner cell mass (ICM) and trophectoderm, blastocyst size at 116hpi; and assessing the likelihood of blastulation (at 30hpi) and implantation. We evaluated the statistical significance for all variables using t-tests (continuous variables) and chi-squared tests (categorical variables). We quantified the two pronuclei (2PN) detection efficacy using four metrics: accuracy, sensitivity, specificity, and informedness.
Main results and the role of chance
Of all the embryos analysed (n = 9284), 35% showed DUCs (n = 3269). Blastulation was significantly higher in non-DUC versus DUC embryos (76% and 49%, p < 0.0001). Of the embryos that blastulated, ICM quality (A,B,C,D: 24%,13%,19%,21% and 3%,4%,16%,47%, p < 0.001) and trophectoderm quality (20%,21%,15%,23% and 2%,7%,14%,52%, p < 0.0001) were significantly higher in non-DUC than in DUC embryos.
As defined, DUC embryos were significantly quicker at reaching t3 than non-DUC [Mean(SD): 34(15) and 39(10), p < 0.0001], with the minimum times being 4hpi and 13hpi respectively. Interestingly, there was no significant difference in achieving t5 [52(21) and 51(12), NS]. For all other morphokinetic milestones, DUC embryos were 6 hours slower than non-DUC embryos. DUC embryos had an euploidy rate of 27.2% (12/44). Only one DUC embryo was transferred in a double embryo transfer cycle leading to a negative outcome.
Implantation score [0.14(0.24) and 0.46(0.36), p < 0.0001] and blastulation score [0.4(0.46) and 0.75(0.4), p < 0.0001] were lower for DUC embryos than for non-DUC embryos.
CHLOE automatic PN assessment agreed with human annotation in 92% of cases (TP = 388,TN=5,FP=29,FN=7). CHLOE Blastocyst prediction at 30hpi had an AUC of 0.89. The embryologist agreed on 97% of all 483 embryos that CHLOE classified as DUC. Discrepancies arose from CHLOE misclassifying fragments as blastomeres. Further studies warranted.
Limitations, reasons for caution
Differentiating between fragments and blastomeres within the 5 hours from the first division proves challenging for embryologists and, especially, AI algorithms. Hence, some embryos’ DUC status may be misclassified. Additionally, our sample sizes are limited and larger sizes are needed to corroborate our findings, especially those pertaining to ploidy status.
Wider implications of the findings
DUC embryos are associated with poorer outcomes and DUC status should be integrated into embryo classification frameworks. Nevertheless, some DUC embryos prove to be euploid. Hence, DUC embryos should not excluded from culture at cleavage stage and instead be allowed to reach blastocyst stage before assessing their suitability for transfer/vitrification/PGT-A.

Abstract
Abstract
Study question
Is raised paternal body mass index (BMI) important for the miscarriage rate following assisted reproductive technology (ART)?
Summary answer
Based on the available evidence, raised male BMI is not associated with higher risk of miscarriage following ART.
What is known already
More than half women and men of reproductive age worldwide are overweight or obese.There is extensive literature exploring the importance of normal female BMI for reproductive outcomes. However, little attention has been given to male BMI for couples seeking fertility treatment [1] .The adverse effect of male obesity on sperm parameters including DNA damage is well documented and there is evidence suggesting that raised male BMI results in significant decrease in live birth rate following ART [2] .Furthermore, emerging evidence from human and animal studies demonstrates that paternal obesity can affect the future health of the offspring through epigenetic pathways[3].
Study design, size, duration
A computerized literature search was performed using EMBASE, MEDLINE, CINAHL and the Cochrane Central register of trials from database inception to November 2021. The aim was to explore the association between male BMI on miscarriage rate following ART. Reference lists of relevant studies were cross-checked. Only articles with full manuscripts available and published in English were included. Papers not relating to human subjects were excluded. All eligible studies were included (observational, prospective and retrospective studies).
Participants/materials, setting, methods
Included studies reported on couples undergoing ART for any indication using partner’s fresh sperm. Outcomes of interest were miscarriage rate and clinical pregnancy rate. Outcome data from each study were pooled and expressed as odds ratio (OR) with 95% confidence interval (CI) by using a random-effect model due to statistical heterogeneity in the outcome data[4]. Heterogeneity of treatment effects was evaluated using the I2 statistic to quantify the variation across studies caused by heterogeneity.
Main results and the role of chance
Abstract screening identified 197 relevant studies. After excluding duplicates, reviews and studies which did not fulfill the inclusion criteria, full manuscripts were accessed for 13 studies. Six studies were identified exploring the effect of male BMI on miscarriage following ART, two prospective and four retrospective. The quality of evidence was low using the GRADE framework. Meta-analysis was possible for three studies including 6793 couples undergoing ART. Outcomes were compared for male BMI < 25 kg/m2 versus BMI >/=25 kg/m2 . The pooled results did not show a statistically significant increase in miscarriage rate when the male partner was overweight or obese compare to normoweight (OR 1.32, 95% CI 0.82–2.1, P = 0.249). There was significant heterogeneity between the included studies (I 2 = 48.7%). There was no significant effect of male BMI on clinical pregnancy rate (OR 0.90, 95% CI 0.59–1.38, P = 0.637). For two of the remaining studies which could not be included in the meta-analysis due to missing data, the authors concluded that male BMI >25 was not associated with increased miscarriage risk whilst the most recent prospective study showed that high male BMI was associated with increased risk of chromosomal aberration-related miscarriages.
Limitations, reasons for caution
The number of the included studies and significant heterogeneity are the main limitations. It was not possible to account for important confounders such as age, subfertility diagnosis, type of stimulation and laboratory parameters including embryo grade. We grouped participants in two BMI categories therefore did not distinguish between overweight/obesity/morbid obesity.
Wider implications of the findings
Despite increasing evidence suggestive of adverse effect of raised male BMI on reproductive outcomes, there is limited literature exploring the impact on miscarriage rate following ART. More well-designed studies are needed for sound conclusions. Paternal characteristics, general health and preconception lifestyle should not be overlooked in the fertility consultation.

Abstract
Background The widespread use of digital devices causes adolescents to spend long periods of time in front of the screen. Aims This study aimed to analyze the impacts of digital game addiction on the musculoskeletal system of secondary school children in Kayseri. Patients and Methods A total of 1000 healthy children have been included. A questionnaire, which has been prepared by the researchers and questions children's socio-demographic knowledge, sport habits, durations of study, types of digital tools they use to play games, using positions and durations of use, has been applied to the children. A visual analog scale was used to assess pain intensity. Game addiction has been evaluated through Computer Game Addiction Scale for Children. Results Between computer and phone use and neck pain, a significant correlation has been found (P < 0.05). Between game addiction and wrist, back and low back pain, a significant correlation has been detected. While males use more computer, tablet and are more addicted to games, the scores of head, wrist and back pain in females have been found out to be significantly high. Conclusions As they cause musculoskeletal problems, the higher the time children consume in front of digital devices and the more they use it in wrong posture; the more the complaints about pain are.

Abstract
PURPOSE OF THE STUDY As in orthopedic trauma patients, a hyperinflammatory response due to cytokine release occurs in patients with moderate and severe COVID-19 infection. In these patients, untimely surgical intervention can create more destructive situations in the postoperative period. Our aim in this study was to investigate the effect of COVID-19, trauma and surgical intervention on acute phase reactants' levels in patients with and without COVID-19 infection. MATERIAL AND METHODS Twenty-four patients diagnosed with COVID-19 infection and major fractures requiring surgical treatment were evaluated retrospectively (Group 1). Twenty-four COVID-19 negative patients with similar trauma were included in the study as a control group (Group 2). These two groups were compared in terms of demographic data, time to surgery, total hospitalization time, and preoperative and postoperative acute phase reactants' [C-reactive protein (CRP), D-dimer, ferritin, fibrinogen and white blood cell (WBC)] values. RESULTS Time to surgery was 8.3 ± 0.7 days and the total hospital stay was 15.2 ± 0.8 days, in Group 1. These values were determined as 3.3 ± 0.4 and 6.5 ± 0.6 days, respectively for the patients in Group 2 (p < 0.001 and p < 0.001, respectively). When the acute phase reactant values studied during admission were examined, a significant difference was found between the two groups in terms of CRP, D-dimer, ferritin and WBC (p = 0009, p = 0.002, p < 0.001 and p < 0.001, respectively). In the preoperative period, a significant difference was observed between the groups in terms of CRP and ferritin (p = 0.011, p < 0.001, respectively). A significant difference was found only in terms of ferritin from the laboratory values studied in the postoperative period (p < 0.001). DISCUSSION To our knowledge, the present study is the first study which compares and investigates the effects of COVID-19 infection, major fracture and surgical intervention on acute phase reactants' values. Surgical treatment is generally recommended as soon as possible in daily orthopedic practice. However, in patients with asymptomatic or mildly symptomatic COVID-19 infection, it remains unclear how long surgical intervention will be delayed after admission and clinical stabilization of patients with a fracture that requires surgical fixation. In a meta-analysis, patients with COVID-19 infection accompanying hip fracture had a mortality rate of 32.6% in the early postoperative period, and the mortality risk of these patients was found to be 5.66 times higher compared to patients without COVID-19 infection. In our study, one patient (4.2%) with COVID-19 infection who underwent partial hip arthroplasty due to femoral neck fracture. CONCLUSIONS The follow-up and treatment of patients with COVID-19 infection with accompanying a major fracture requiring orthopedic surgery is a complex situation. We recommend that acute phase reactants such as CRP, D-dimer, erythrocyte sedimentation rate (ESR), and ferritin should be closely monitored in these patients during the period from admission to surgery, and surgical intervention should be performed while these values are in remission or decline. Key words: COVID-19, fracture, trauma, acute phase reactants, surgical timing.

Abstract
Abstract
Background
Transcatheter aortic valve implantation (TAVI) is a less invasive and safe therapeutic alternative in patients who are at very high surgical risk or in whom there are contraindications to open surgery (1,2).On the other hand, life threatening complications including stroke, paravalvular leak, and rhythm disturbances that require permanent pacing still persist (3).Fragmented QRS (fQRS) is defined as RSR' pattern with different morphologies of QRS complexes with or without the Q wave on a resting 12-lead electrocardiogram (ECG) (4).
Purpose
In this study, we examined association between fQRS and post-procedural rhythm disturbances and the need for permanent pacing in patients who underwent TAVI with CoreValve system.
Methods
We analysed standard 12-lead electrocardiographic recordings of 124 consecutive patients in whom a CoreValve prosthesis (MedronicInc; Minneapolis; USA) was implanted. Patients having bundle branch block or QRS duration ≥120 ms in baseline ECG recordings and patients with prior history of permanent pacing were excluded from the study. We examined 12-lead ECGs before and after procedure along with one month and six month follow up. We documented QRS fragmentation and post-procedural rhythm disturbances.
Results
Based on our data, 39 out of 71 patients (54.9%) with fQRS developed temporary rhythm disturbances. However, only 4 out of 29 patients (13.7%) without fQRS developed temporary rhythm disturbances.The difference between two groups in terms of temporary rhythm disturbances was statistically significant (59.4% vs 13.7%, p=0.002). Furthermore, 28 out of 71 patients (39.4%) with fQRS and 1 out of 29 patients (3.4%) without fQRS developed permanent rhythm disturbances, (39.4% vs 3.4%, p<0.001).The difference in permanent rhythm disturbances was also maintained in 1st month and 6th-month follow-ups (37.1% vs 0%, p<0.0001, and 38.7% vs 0%; p<0.0001). According to our data, presence of QRS in anterior derivations was the only independent factor associated with development of post-procedural rhythm disturbances (p<0.05).
Conclusion
Our data showed an increased risk for development of new-onset LBBB and AV blocks following TAVI in patients whose baseline ECG recordings demonstrated fQRS.

Abstract
BACKGROUND The incidence of lymphatic complications after kidney transplantation varies considerably in the literature. This is partly because a universally accepted definition has not been established. This study aimed to propose an acceptable definition and severity grading system for lymphatic complications based on their management strategy. METHODS Relevant literature published in MEDLINE and Web of Science was searched systematically. A consensus for definition and a severity grading was then sought between 20 high-volume transplant centres. RESULTS Lymphorrhoea/lymphocele was defined in 32 of 87 included studies. Sixty-three articles explained how lymphatic complications were managed, but none graded their severity. The proposed definition of lymphorrhoea was leakage of more than 50 ml fluid (not urine, blood or pus) per day from the drain, or the drain site after removal of the drain, for more than 1 week after kidney transplantation. The proposed definition of lymphocele was a fluid collection of any size near to the transplanted kidney, after urinoma, haematoma and abscess have been excluded. Grade A lymphatic complications have a minor and/or non-invasive impact on the clinical management of the patient; grade B complications require non-surgical intervention; and grade C complications require invasive surgical intervention. CONCLUSION A clear definition and severity grading for lymphatic complications after kidney transplantation was agreed. The proposed definitions should allow better comparisons between studies.

Abstract
Chronic ischemia of the lower extremities is an everyday problem in vascular surgery clinics. In Germany, approximately 3% of all hospitalizations are due to peripheral artery disease (PAD), with critical limb ischemia (CLI) in particular showing a rapid increase. The consequences of chronic undersupply range from reduced walking distance to loss of limbs. At the beginning there are stress factors, such as hyperlipidemia (LDL), free radicals, arterial hypertension, infections or subclinical inflammation that interfere with endothelial homeostasis and cause endothelial dysfunction with increased permeability. Cells of the immune system are attracted and migrate into the vascular wall, where they lead to the degradation of matrix components and destabilization of the plaque. By changing the phenotype of smooth muscle cells and macrophages towards osteoclast-like cells, bone-like hardening of the vessel wall takes place. Above a vessel wall thickness of approximately 100 µm, hypoxia-induced factor (HIF-1α) is intensified by the lack of oxygen, which leads to an increase in growth factors, such as vascular endothelial growth factor (VEGF). This promotes angiogenesis, but it is not sufficient to compensate for a stenosed artery. Arteriogenesis refers to the growth of existing collateral vessels. The driving forces are the pressure gradient before and after the stenosis and the shear forces acting on the vessel walls. In the case of progressive stenosis, the compensatory capacities can be overtaxed and a manifest hypoxia in the tissue with regression of the obtained vascular structures and tissue atrophy occurs.

Abstract
The objective of the current study was to assess the influence of a modified crushing process and kneading operation on the quality parameters, volatile compounds, and the fatty acid and sterol profiles of virgin olive oil from the Edremit yaglik variety. In the study, olive oil samples were produced in two different processes. The first one was produced without malaxation and the second one was produced with the malaxing process. During crushing, the effect of different temperatures was tested. The results demonstrate that different crushing temperatures generally did not affect the amount of free fatty acids, or peroxide value. Total phenol contents were positively affected by the additional malaxation process. Fatty acids and sterol composition were not significantly altered at different crushing temperatures or during the subsequent malaxation application. PCA enabled a clear classification of the oils obtained from different processing techniques.

Abstract
AIMS Diabetic kidney disease independently predicts cardiovascular disease and premature death. We examined the burden of chronic kidney disease (CKD, defined as an estimated GFR < 60 ml/min/1.73 m(2) ) and quality of care in a cross-sectional survey of adults (age ≥ 18 years) with Type 2 diabetes across Asia. METHODS The Joint Asia Diabetes Evaluation programme is a disease-management programme implemented using an electronic portal that systematically captures clinical characteristics of all patients enrolled. Between July 2007 and December 2012, data on 28 110 consecutively enrolled patients (China: 3415, Hong Kong: 15 196, India: 3714, Korea: 1651, Philippines: 3364, Vietnam: 692, Taiwan: 78) were analysed. RESULTS In this survey, 15.9% of patients had CKD, 25.0% had microalbuminuria and 12.5% had macroalbuminuria. Patients with CKD were less likely to achieve HbA1c < 53 mmol/mol (7.0%) (36.0% vs. 42.3%) and blood pressure < 130/80 mmHg (20.8% vs. 35.3%), and were more likely to have retinopathy (26.2% vs. 8.7%), sensory neuropathy (29.0% vs. 7.7%), cardiovascular disease (26.6% vs. 8.7%) and self-reported hypoglycaemia (18.9% vs. 8.2%). Despite high frequencies of albuminuria (74.8%) and dyslipidaemia (93.0%) among CKD patients, only 49.0% were using renin-angiotensin system inhibitors and 53.6% were on statins. On logistic regression, old age, male gender, tobacco use, long disease duration, high HbA1c , blood pressure and BMI, and low LDL cholesterol were independently associated with CKD (all P < 0.05). CONCLUSIONS The poor control of risk factors, suboptimal use of organ-protective drugs and high frequencies of hypoglycaemia highlight major treatment gaps in patients with diabetic kidney disease in Asia.

Abstract
BACKGROUND/OBJECTIVES Nutritional deficiencies are frequently observed when treating patients with inborn errors of metabolism due to an unbalanced diet. Thus far, patients with isovaleric acidemia (IVA) who adhere to a restricted protein diet have not been investigated in this respect. We hypothesize that these patients may have a polyunsaturated fatty acid (PUFA) deficiency, leading to potential clinical complications. SUBJECTS/METHODS We examined the nutritional status by reporting on potential deficiencies in PUFAs in treated IVA patients. A general clinical chemistry work-up as well as gas chromatography flame ionization detector analysis was performed to determine PUFAs in the plasma of 10 IVA patients. RESULTS The general clinical chemistry tests did not indicate severe hematological abnormalities or nutritional insufficiencies. We identified a significant reduction in plasma PUFA levels, especially in omega-3 (all acids, P<0.001) and omega-6 (in particular 20:3n-6 P<0.0001 and 20:4n-6 P=0.0005) fatty acids. In addition, an elevation in omega-9 fatty acids, with the exception of 20:3n-9 and C22:1n-9, was not suggestive of complete essential fatty acid deficiency but rather indicative of isolated and/or combined omega-3 and omega-6 fatty acid depletion. CONCLUSIONS This study emphasizes the potential nutritional insufficiencies that may occur because of therapeutic intervention in IVA.

Abstract
IntroductionDelirium is a clinical entity consisting of acute loss of consciousness, with attention deficit and fluctuating evolution. Antidepressive medication can cause these symptoms or worsen them.Case reportWe report the case of a 84-year-old blind female who was diagnosed of delirium in relation to intoxication with sertraline. The patient was admitted into a short-stay psychiatric unit for three days. She presented behavioural disturbances consisting in auto and heteroaggressive behaviour, altered consciousness and visual hallucinations (rocks, turtles). When dosage of sertraline was doubled from 50 mg/day to 100 mg/day visual hallucinations started. There were not other medical causes found, so sertraline was suspended, achieving clinical improvement.DiscussionThis case report shows how a patient with antidepressive treatment can display delirium. The three main causes of delirium that are infections, side effects and methabolic syndrome.ConclusionsIn the case of treating a patient with delirium, the presence of previous illness has to be investigated. It is indispensable to describe the presence of previous illness, medication and recent changes of the dosages in the medical history in a patient with Sertraline.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
FMR1 premutation female carriers are at risk for Fragile X-associated primary ovarian insufficiency (FXPOI). Insights from knock-in mouse model have recently demonstrated that FXPOI is due to an increased rate of follicle depletion or an impaired development of the growing follicles. Molecular mechanisms responsible for this reduced viability are still unknown. In an attempt to provide new data on the mechanisms that lead to FXPOI, we report the first investigation involving transcription profiling of total blood from FMR1 premutation female carriers with and without FXPOI. A total of 16 unrelated female individuals (6 FMR1 premutated females with FXPOI; 6 FMR1 premutated females without FXPOI; and 4 no-FXPOI females) were studied by whole human genome oligonucleotide microarray (Agilent Technologies). Fold change analysis did not show any genes with significant differential gene expression. However, functional profiling by gene set analysis showed large number of statistically significant deregulated GO annotations as well as numerous KEGG pathways in FXPOI females. These results suggest that the impairment of fertility in these females might be due to a generalized deregulation of key signaling pathways involved in oocyte maturation. In particular, the vasoendotelial growth factor signaling, the inositol phosphate metabolism, the cell cycle, and the MAPK signaling pathways were found to be down-regulated in FXPOI females. Furthermore, a high statistical enrichment of biological processes involved in cell death and survival were found deregulated among FXPOI females. Our results provide new strategic approaches to further investigate the molecular mechanisms and potential therapeutic targets for FXPOI not focused in a single gene but rather in the set of genes involved in these pathways.

Abstract
INTRODUCTION Popliteal artery aneurysms (PAA) are rare. Different surgical techniques for open surgical repair are possible. This study presents a single centre experience using open surgical repair with a medial approach (MA) and outlines differences between symptomatic (SLS) and asymptomatic (ALS) legs. METHODS Data collection was performed retrospectively. The investigation period was from 1 January 1996 to 1 January 2013. Patients presented in the Outpatient Department and received a questionnaire concerning their quality of life. Data are presented as mean ± standard deviation. Mann-Whitney test and Cochran-Armitage test for trend was used for data analysis. Kaplan-Meier method was used to calculate limb salvage rates. p < 0.05 was considered statistically significant. RESULTS We analyzed 16 ALS and 26 SLS with an average age of 63.5 ± 10 years. Preoperative ankle-brachial index (ABI) was 1.0 ± 0.2 for ALS (on control examination: 1.12 ± 0.24) and 0.08 ± 0.18 for SLS (on control examination 0.94 ± 0.14) (p < 0.05). Limb salvage rate was 100% for ALS and 86.7% for SLS (overall 93.3%). Primary patency rate for SLS was 85%, for ALS rate of 100%, respectively (overall 92.5%). ALS reached an average of 13.1 ± 2.7 points (SLS 11.4 ± 2.8) on a numeric point scale. CONCLUSION Open surgery is therapy and prevention of acute ischaemia all in one, especially for asymptomatic patients and delivers good long-term results. Endovascular therapies offer an alternative but long-term results are pending. Open surgery should still be considered as a gold standard therapy.

Abstract
In this review, we analyze the efficacy and safety of DT56a in the treatment of postmenopausal symptoms. Similar to all selective estrogen receptor modulators (SERMs), DT56a demonstrates dual agonistic and antagonistic effects due to the synergy between its components. DT56a is referred to as a plant-origin SERM (phyto-SERM) and, for this reason, its therapeutic capacity in postmenopausal women differs from other phytoestrogens used independently. Although interesting data on relief of vasomotor symptoms have been reported for DT56a, further clinical studies with a greater number of cases and a longer period of study are required to correctly identify its indications for use as an alternative to hormone therapy, especially in preventing osteoporosis.

Abstract
OBJECTIVES To study the effects of cigarette smoke and vitamin E on the development of endometrial pinopods. STUDY DESIGN Eighteen female and 12 male Swiss albino mice, 12-14 weeks old, with a mean weight of 25g (standard deviation 5g) were used in this study. Female mice were divided into three equal groups. Every day for 10 weeks, mice in Group 1 (control group) received normal saline intraperitoneally; mice in Group 2 were exposed to smoke from 20 cigarettes/day using a smoke machine; and mice in Group 3 were exposed to smoke from 20 cigarettes/day using a smoke machine and also received 50mg/kg vitamin E intraperitoneally. After 10 weeks, vaginal smears were taken from the female mice and they were copulated with the 12 male Swiss albino mice on the day of oestrus. Day 0 was defined as the day on which sperm were detected in the vagina by smear test. Mice were killed at the end of Day 5, which was considered to represent the optimal day for implantation. The uteri were removed and the effects of cigarette smoke and vitamin E on the development of endometrial pinopods were studied using an electron microscope. RESULTS The endometrial tissue of the control group appeared morphologically normal, with short microvilli, cytoplasm and pinopods in the form of cytoplasm and cell membrane enlargements in patches. In total, 149 pinopods were counted in the control group using a scanning electron microscope (two histologists performed the analysis and were blinded to each other's findings). In the smoke-exposed group, the cytoplasmic structure was degenerated considerably, and fewer pinopods were counted (n=11). The number of pinopods in mice who were exposed to cigarette smoke and vitamin E (n=67) was significantly higher compared with the cigarette-exposed group (p=0.002), but considerably lower compared with the control group (p=0.002). CONCLUSION Smoke exposure led to a significant decrease in the development of endometrial pinopods. Vitamin E, an antioxidant, partially reversed the adverse effects of cigarette smoke. This suggests that cigarettes may have a negative effect on fertility by decreasing the number of pinopods. However, this negative effect can be reduced using vitamin E. More studies should be conducted to support this finding.

Abstract
PURPOSE We aimed to determine the effect of intravenous thrombolytic therapy on QT dispersion (QTd) and its role in the prediction of reperfusion arrhythmias. MATERIALS AND METHODS Twenty patients with acute myocardial infarction (MI) were enrolled in the study. Measurements of QTd were carried out prior to thrombolytic therapy and before discharge. The patients were examined for ventricular arrhythmias with 24-h Holter electrocardiography monitoring after treatment and the relationship between ventricular arrhythmias and the QTd values in the early phase of MI was investigated. RESULTS The values of QTd were significantly higher during the early phase of MI (60 ± 5.32 ms) than those in the late phase (53.35 ± 4.07 ms) (P = 0.032). There was no correlation between isolated, bigeminal, trigeminal and total ventricular premature beats, accelerated idioventricular rhythm (AIVR) with QTd values. However, the patients with sustained ventricular tachycardia (VT), prolonged VT and sustained AIVR had higher corrected QTd (92 ms 1/2 , 97.8 ms 1/2 , 81.7 ms 1/2 , respectively) than the patients without these arrhythmias (74 ms 1/2 , 56.3 ms 1/2 , 58.28 ms 1/2 , respectively) (P = 0.022, 0.013, 0.018). CONCLUSION The values of QTd may be significantly reduced in the 1 st week of acute MI and measurement of QTd in the early phase of MI may have a correlation with the following reperfusion arrhythmias: Sustained VT, prolonged VT and AIVR.

Abstract
OBJECTIVE We aimed to elucidate the relationship between mild-to-moderate renal impairment and the development of coronary collateral vessels (CCV) in patients with acute coronary syndrome (ACS). METHODS We enrolled 461 patients with ACS who underwent coronary angiography for the first time. The development of CCV was assessed with the Rentrop score. Kidney function was classified according to the estimated glomerular filtration rate (eGFR). The Gensini score was used to show the extent of atherosclerosis. RESULTS The mean eGFR value was 89.9 ± 24.3 U/l for patients with no development of collaterals and 82.7 ± 20.5 for patients who had CCV. The mean age was 59 ± 11 years and 349 patients (75.7 %) were male. Rentrop classifications 1-2-3 (presence of CCV) were determined in 222 (48.1 %) patients. The presence of CCV was significantly associated with low levels of eGFR (p = 0.001), increased serum creatinine levels (p = 0.034), high levels of serum albumin (0.036), and the Gensini score (p < 0.001). Multivariate analysis showed that the Gensini score was an independent predictor of the presence of CCV (OR = 1.090, 95 % CI: 1.032-1.151, p = 0.002). CONCLUSION We suggest that the association between mild-to-moderate renal impairment and the presence of CCV may be explained by increased myocardial ischemia and severe CAD.

Abstract
Hyperammonemia is a frequent finding in various organic acidemias. One possible mechanism involves the inhibition of the enzyme N-acetylglutamate synthase (NAGS), by short-chain acyl-CoAs which accumulate due to defective catabolism of amino acids and/or fatty acids in the cell. The aim of this study was to investigate the effect of various acyl-CoAs on the activity of NAGS in conjunction with the formation of glutamate esters. NAGS activity was measured in vitro using a sensitive enzyme assay with ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) product analysis. Propionyl-CoA and butyryl-CoA proved to be the most powerful inhibitors of N-acetylglutamate (NAG) formation. Branched-chain amino acid related CoAs (isovaleryl-CoA, 3-methylcrotonyl-CoA, isobutyryl-CoA) showed less pronounced inhibition of NAGS whereas the dicarboxylic short-chain acyl-CoAs (methylmalonyl-CoA, succinyl-CoA, glutaryl-CoA) had the least inhibitory effect. Subsequent work showed that the most powerful inhibitors also proved to be the best substrates in the formation of N-acylglutamates. Furthermore, we identified N-isovalerylglutamate, N-3-methylcrotonylglutamate and N-isobutyrylglutamate (the latter two in trace amounts), in the urines of patients with different organic acidemias. Collectively, these findings explain one of the contributing factors to secondary hyperammonemia, which lead to the reduced in vivo flux through the urea cycle in organic acidemias and result in the inadequate elimination of ammonia.

Abstract
The objective of the study was to identify the impact of co-digesting clarifier skimmings on the overall methane generation from the treatment plant and additional energy value of the increased methane production. Biogas production from co-digesting clarifier skimmings and sewage sludge in pilot-scale fed-batch mesophilic anaerobic digesters has been evaluated. The digester was fed with increasing quantities of clarifier skimmings loads: 1.5, 2.6, 3.5 and 7.0 g COD equivalent/(L·d) (COD: chemical oxygen demand). Average volatile solids reduction of 65% was achieved in the scum-fed digester, compared with 51% in the control digester. Average 69% COD removal was achieved at highest scum loading (7 g COD eq/(L·d)) with approximate methane yield of 250 L CH(4)/kg COD fed (4 ft(3)/lb COD fed). The results show that scum as co-substrate in anaerobic digestion systems improves biogas yields while a 29% increase in specific CH(4) yield could be achieved when scum load is 7 g COD eq/(L·d). Based on the pilot-scale study results and full-scale data from South East Water Pollution Control Plant and Northeast Water Pollution Control Plant the expected annual energy recovery would be approximately 1.7 billion BTUs or nearly 0.5 million kWh.

Abstract
Isovaleric acidemia (IVA) is one of the most common organic acidemias found in South Africa. Since 1983, a significant number of IVA cases have been identified in approximately 20,000 Caucasian patients screened for metabolic defects. IVA is caused by an autosomal recessive deficiency of isovaleryl-CoA dehydrogenase (IVD) resulting in the accumulation of isovaleryl-CoA and its metabolites. In total, 10 IVA patients and three carriers were available for phenotypic and genotypic investigation in this study. All patients were found to be homozygous for a single c.367 G > A (p.G123R) mutation. The amino acid substitution of a glycine to arginine resulted in a markedly reduced steady-state level of the IVD protein, which explains the nearly complete lack of IVD enzyme activity as assessed in fibroblast homogenates. Despite the genetic homogeneity of this South African IVA group, the clinical presentation varied widely, ranging from severe mental handicap and multiple episodes of metabolic derangement to an asymptomatic state. The variation may be due to poor dietary intervention, delayed diagnosis or even epigenetic and polygenetic factors of unknown origin.

Abstract
Two unrelated individuals were referred to Lipid Clinics in The Netherlands and Chile with extreme xanthomatosis and hypercholesterolemia. Both were diagnosed with heterozygous familial hypercholesterolemia (heFH) after molecular genetic analysis of the low-density lipoprotein (LDL) receptor gene. Since heFH by itself could not account for the massive xanthomas, the presence of an additional hereditary lipid or lipoprotein disorder was suspected. Further genetic analysis revealed homozygozity for mutations in the sterol 27-hydroxylase gene, confirming the diagnosis of cerebrotendinous xanthomatosis (CTX). Markedly, the typical neurological manifestations of CTX were absent, suggestive of a protective role of LDL-receptor deficiency against the severe neurological consequences of CTX.

Abstract
Hydronephrosis is the most common congenital anomaly observed with prenatal ultrasonography. Ureteropelvic junction obstruction (UPJO) is the most common cause of prenatal hydronephrosis. Spontaneous rupture has been reported in adults with severe hydronephrosis. There is no reported spontaneous rupture case in the fetus in the literature. A spontaneous ureteral rupture due to severe UPJO was reported in this case report. Prenatal ultrasound at 33 week gestation in a 21-year-old pregnant woman, revealed a female fetus with grade IV hydronephrosis of the right kidney, suggestive of a UPJO. During the follow-up at XXXVIII week, 5 cm cystic structure was not observed in right kidney. Mild ectasia was present in pelvicalyciel part which make us think about spontaneous rupture. Ultrasonographic examination after a week post-delivery revealed 15 mm pelvicalyciel ectasia on right side which persisted during the second control after 1 month. Vesicoureteral reflux was not detected during voiding cystourethrogram. Diuretic renography revealed loss of right renal function completely. Because there was not any complain or any clinical sign, surgery was not thought. Spontaneous follow-up was recommended.

Abstract
OBJECTIVE To investigate the clinical and prognostic features of patients admitted to intensive care unit (ICU) with pandemic 2009 influenza A (H1N1) virus. METHODS Patients admitted to the intensive care unit for severe pneumonia associated with pandemic 2009 influenza A (H1N1) virus were evaluated. RESULTS The study included 20 patients with the mean age of 36±13. Of the 20 subjects, 17 (85%) had underlying conditions. Of the 20 patients, 11(55%) were discharged and 9 (45%) died. Cardinal symptoms were fever, myalgia, and hemoptysis with the rates of 85 %, 75 % and 45 %, respectively. All patients had pneumonic infiltrations in their chest roentgenograms. Main laboratory findings were lymphopenia, high creatin phosphokinase (CPK) and Lactate dehydrogenase (LDH) levels. All patients had positivity on real time reverse transcription-polymerase chain reaction (RT-PCR). None of the patients had pandemic 2009 influenza A (H1N1) virus vaccination. None of them had taken oseltamivir within 48 hours. Main reasons for mortality were cardiovascular complications and ventilatory associated pneumonia due to Acynetobacter baumannii. CONCLUSION Early diagnosis and antiviral treatment in these cases seem to be the best approach to avoid serious illness. Special attention should be given to patients having underlying conditions such as cardiovascular and pulmonary diseases and pregnancy.
