Abstract
Bacteria can form biofilms on any surface, which causes biofilm-associated infections and bacterial resistance to antibiotics. Thus, it is important to design new-generation non-chemotherapeutic nanoagents for effective antibacterial and antibiofilm strategies. Herein, the effects of the anchoring groups, which are imidazole and carboxylic acid, of zinc phthalocyanines (ZnPcs) sensitized TiO2 on Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) were investigated under light-emitting diode (LED) irradiation. The photocatalytic antibacterial activities of ZnPc-1/TiO2 and ZnPc-2/TiO2 on the bacterial strains were examined by monitoring the optical density value at 600 nm (OD600 nm). Glutathione (GSH) oxidation assay was used to measure the reactive oxygen species (ROS) generation activity of the compounds. Bacterial damages were imaged by scanning electron microscopy (SEM). According to our photocatalytic antibacterial mechanism, photogenerated electrons are transferred from Pcs to TiO2 and then react with O2, thus creating ROS, which causes damage to bacterial membrane, protein and biofilm destruction as well. Further, computational simulation analysis was used to show the interaction patterns of ZnPc-1 and ZnPc-2 with penicillin binding protein 2a (PBP2a) of S. aureus and FimH lectin protein (PDB:4XO8) of E. coli to elucidate the dark molecular antibacterial mechanism of the compounds. The obtained results from computational studies showed that ZnPc-2 binds firmly through bonds with the 1MWT protein from S. aureus. On the other hand, ZnPc-1 binds firmly through bonds with the 4XO8 protein from E. coli. From combining experimental and computational results, we can conclude that this strategy can be applied to different types of bacterial infections.

Abstract
This study was aimed to coat a hybrid bioceramic composite onto Ti6Al4V by using hydrothermal method. The Hybrid bioceramic composite for coating was prepared by reinforcing different rations of expanded perlite (EP) and 5 wt.% chitosan into synthesized Hydroxyapatite (HA). Coating was performed at 1800°C for 12 hours. The coated specimens were gradually subjected to a sintering at 6000°C for 1 hour. For in vitro analysis, the specimens were kept in Ringer's solution for 1, 10, and 25 days. All specimens were examined by SEM, EDX, FTIR, and surface roughness analyses for characterizing. It was concluded that as the reinforcement ratio increased, there was an increase in coating thickness and surface roughness. The optimum reinforcement ratio for expanded perlite can be 10 wt.% (A3-B3). With increasing ratio of calcium (Ca) and phosphate (P) (Ca/P), the surface becomes more active in body fluid and then observed the formation of the hydroxycarbonate apatite (HCA) layer. As the waiting time increased, there was an increase in the formation of an apatite structure.

Abstract
OBJECTIVES Neurocognitive functions of children with type 1 diabetes mellitus (T1D) are reported to be poorer than those of healthy peers. The aim was to investigate the effects of age of onset of diabetes, metabolic control, and type of insulin regimen on neurocognitive functions in children and adolescents with T1D. METHODS Forty-seven children aged 6-18 years, with T1D for at least five years, were included. Children with a known psychiatric disorder or chronic diseases other than T1D were excluded. Intelligence via the Wechsler children's intelligence scale (WISC-R), short-term memory via the audio-auditory digits form B (GISD-B) test, visual motor perception via the Bender Gestalt test, and attention via the Moxo continuous attention and performance test, timing, hyperactivity, and impulsivity (Moxo-dCPT) were assessed. RESULTS Compared with the T1D group, healthy controls had higher scores in terms of verbal intelligence quotient (IQ), performance IQ, and total IQ mean scores on WISC-R (p=0.01, p=0.05 and p=0.01, respectively). On the MOXO-dCPT test, the T1D group had higher impulsivity compared to the control group (p=0.04). Verbal IQ was better in the moderate control group than in the poorer metabolic control (p=0.01). Patients with no history of diabetic ketoacidosis (DKA) had higher performance, verbal and total intelligence scores than the group with history of DKA. CONCLUSIONS Poor metabolic control and a history of DKA in children with T1D adversely affected neurocognitive functions. It would be beneficial to consider the assessment of neurocognitive functions in T1D and to take the necessary precautions in follow-up.

Abstract
OBJECTIVE The aim of this study was to assess the quality of life (QoL) and psychological well-being in child and adolescent with disorders of sex development (DSD). METHODS Sixty-two cases, aged 2-18 years, who were followed by a multidisciplinary DSD team were included. All participants and their parents were requested the complete the Pediatric Quality Of Life Inventory (PedsQL) and the Strengths and Difficulties Questionnaire. The psychiatric diagnoses of the patients were evaluated according to Schedule for Affective Disorders and Schizophrenia for School-Age Children/Present and Lifetime Turkish Version. RESULTS There was no significant difference between the 46,XX DSD and 46,XY DSD groups for both child and parent in Total PedsQL score. In the subscale scores, the PedsQL Physical Functionality Score reported by children was significantly lower for the 46,XX DSD group than for the 46,XY DSD group (p=0.01). There was a psychiatric diagnosis in 25.8% of cases. The PedsQL School Functionality Score reported by children in the group with psychiatric diagnosis was significantly lower than the group without psychiatric diagnosis (p=0.018). In the group with psychiatric diagnosis, the PedsQL Total Score and the subscale scores (Emotional Functionality Score, Social Functionality Score, School Functionality) reported by parents were significantly lower than in parents of the group without psychiatric diagnosis. CONCLUSION This study emphasized that psychiatric disorders in DSD patients negatively affect the QoL. Psychiatric support and counseling from a multidisciplinary team are very important for families affected by DSD.

Abstract
Background Psychiatric consultation is important in the follow-up of disorders of sex development (DSD) patients. In this study, we aimed to present the 12-year psychiatric follow-up data of the patients who were referred by Ege University Medical Faculty DSD Multidisciplinary Team and followed up in Child and Adolescent Psychiatry. Methods Psychiatric data of 118 patients, who were followed by the DSD multidisciplinary team between 2007 and 2019, were reviewed retrospectively. The psychiatric diagnoses of the patients were evaluated according to semi-structured interview form Schedule for Affective Disorders and Schizophrenia for School-Age Children/Present and Lifetime Turkish Version. Results The mean age of the 118 cases was 13.21 years (±7.18). Endocrine diagnoses of the cases were 46 XX DSD in 35 (29.6%), 46 XY DSD in 81 (68.7%), and chromosome disorders in 2 (1.7%). There was at least psychiatric diagnosis in 36 (30.5%) cases. The most common psychiatric diagnosis was attention deficit and hyperactivity disorder (ADHD) (n = 18, 15.3%). ADHD was most common in congenital adrenal hyperplasia (n = 4, 22.4%) and androgen synthesis defects (ASD) (n = 4, 22.4%); depression was most common in complete gonadal dysgenesis and ASD (n = 3, 23.1%); and mental retardation was most common in ASD (n = 3, 37.5%). Conclusions In order to provide a healthy perspective for cases with DSD, it is important to make a psychiatric evaluation and to share observations and clinical findings in regular team meetings.

Abstract
BACKGROUND Home blood pressure monitoring (HBPM) is one of the measures that increases compliance with antihypertensive therapy. HBPM requires a proper measurement technique as well as an accurate sphygmomanometer. The aim of this study was to assess the characteristics of home sphygmomanometers (HS) in a big city in Turkey. SUBJECTS AND METHOD We assessed the HS of hypertensive patients (n = 452; male: 253, female: 199) who were examined for the first time in our outpatient center. General evaluation of HS included trademark, model, device's age, cuff size, validation and calibration status. RESULTS We interviewed 452 patients and 452 HS were identified. The most common factors affecting the patients' choice for the type and model of the HS were its simplicity and ease of use (28.2%), followed by advertisements (44%), physician's advice (19.3%) and the belief in accurate measurement (< 1%). All patients were unaware of validation and calibration of their devices. CONCLUSION Awareness of both patients and physicians about the validation status of HS is not enough. Some complaints from patients may be associated with using non-validated HS. There is a need for a policy or standard criteria for HS.

Abstract
Chronic inflammation may be one of the factors that contribute to the development of diabetic nephropathy (DN). However, erythropoiesis, erythrocyte circulatory half-life and erythrocyte deformability may be influenced by inflammation. Thus, red blood cell distribution width (RDW) levels increase in inflammatory conditions. We investigated the RDW values and related factors in patients with uncomplicated type 2 diabetes mellitus (DM) and diabetic patients with DN. We carried out a retrospective study on patients with type 2 DM admitted to our hospital. Subjects were divided into three groups. Group 1 consisted of healthy subjects. Group 2 consisted of patients with uncomplicated type 2 DM. Patients with various stages of DN were included in Group 3. The RDW values in group 1 subjects were significantly lower than those in group 2 and 3 patients (p<0.05). The RDW values of group 3 patients were higher than those in the other two groups (p<0.05). While the RDW values had positive correlation with blood pressure, serum creatinine, HbA1c, body mass index, proteinuria, platelet (PLT), triglyceride, low density lipoprotein (LDL), total cholesterol (TC), and fasting blood glucose (r values: 0.95, 0.72, 0.56, 0.86, 0.82, 0.76, 0.88, 0.84, 0.88, 0.86, respectively) (p<0.05 for all), there was negative correlation between estimated glomerular filtration rate (eGFR), albumin, high density lipoprotein (HDL) and RDW levels (r values: −0.92, −0. 88, −0.78, respectively) (p value < 0.05 for all).
