THE RELATIONSHIP BETWEEN ATTACHMENT AND SERUM OXYTOCIN AND HEAT SHOCK PROTEIN-70 LEVELS IN ADOLESCENTS OF PARENTS WITH SCHIZOPHRENIA AND BIPOLAR DISORDER.

BACKGROUND: The aim of this study was to evaluate serum heat shock protein 70 (HSP70) and oxytocin levels, attachment and perceived social support levels in adolescents with parental bipolar disorder (BD) and Schizophrenia (SCZ). SUBJECTS AND METHODS: This study included 9 adolescents with SCZ parents, 30 adolescents with BD parents and 31 healthy adolescents. Brief Symptom Inventory (BSI), Relationship Scale Questionnaire-Adolescent Form (RSQ-A) and Multidimensional Scale of Perceived Social Support (MSPSS) were administered to all participants. In addition, serum HSP-70 and oxytocin levels were evaluated. RESULTS: There was no significant difference between the groups in terms of attachment style, psychiatric symptoms and perceived social support. Serum HSP-70 levels were found to be lower in adolescents whose parents had BD. Serum oxytocin levels of the SCZ group were significantly lower than those of the BD group. CONCLUSIONS: HSP-70 level was found to be lower in adolescents with BD parents. Oxytocin level was found to be lower in adolescents with SCZ parents. These findings suggest that HSP-70 and oxytocin may be a marker of early life stress in adolescents with parental psychopathology. However, studies are needed to evaluate the relationship between attachment, oxytocin and HSP-70 in adolescents exposed to parental psychopathology in early life.

Evaluation of sleep habits, sleep chronotype, and quality of life in children with drug-resistant epilepsy in Turkey.

BACKGROUND/AIM: Drug-resistant epilepsy (DRE) is a condition that affects sleep habits and the quality of life of children unfavorably. The aim of our study was to evaluate the relationship of sleep habits and sleep chronotype with the quality of life and behavioral problems in children with DRE. MATERIALS AND METHODS: In our study, 2-11-year-old children, who were either healthy or diagnosed with DRE, were evaluated. A sociodemographic data form was filled out to evaluate the general characteristics of children. The Children's Sleep Habits Questionnaire (CSHQ) and the Children's Chronotype Questionnaire (CCTQ) for sleep habits, the Pediatric Quality of Life Inventory (PedsQL) for the quality of life, and the Aberrant Behavior Checklist (ABC) for behavioral problems were filled out through face-to-face interviews with parents. RESULTS: Thirty children with DRE and 31 healthy children were included in our study. Statistically significant differences were found in children with DRE compared to the control group in terms of the total and the subscale scores of CSHQ, including sleep onset delay, sleep duration, sleep anxiety, parasomnias, and sleep-disordered breathing (p < 0.001). There were no significant differences between the groups in terms of CCTQ total scores and sleep patterns (p > 0.05). Significant differences were found in PedsQL total and subscale scores, and ABC scores in children with DRE compared to the control group (p < 0.001). Children's Sleep Habits Questionnaire, PedsQL, and ABC scores were significantly correlated with each other in children with DRE. CONCLUSIONS: Our results have shown that sleep habits and the quality of life are poor in children with DRE. Our study has shown that sleep disturbances, quality of life, and behavioral problems are strongly associated with each other in DRE. The recognition and appropriate treatment of sleep disturbances are important for improving the quality of life in children with DRE.

How do older age, gender and risk groups affect protective behaviours and mental health in the COVID-19 pandemic?

BACKGROUND: COVID-19 infection is severe in the presence of older age, male gender and risk factors. The aim of this study was to examine the relationship between the level of anxiety created by immensely spreading COVID-19-related information and age, gender and the presence of risk factors. MATERIAL AND METHODS: The data used in this study were obtained by collecting a 25-question questionnaire created through Google forms with various communication tools. RESULTS: The data of 929 people who answered the questionnaire were used. The level of anxiety increased with age significantly, upon hearing that a person from their age group was harmed by the virus (P < .001). The feelings of being depressed and hopeless significantly increased as the age increased (P < .001). There was no significant difference between the genders in terms of feeling depressed and feeling of lack of joy in life (P = .066, P = .308, respectively). Participants with chronic diseases stated that they felt more depressed and hopeless and a lack of joy in life more frequently (P < .001). CONCLUSION: Our results indicated that individuals with older age and having risk factors were more vulnerable to the stress caused by the pandemic. It is necessary for healthcare providers to identify high-risk groups by considering these situations, in order to make early psychological interventions.

An evaluation of suspected cases of Hantavirus infection admitted to a tertiary care university hospital in Düzce, Turkey, between 2012 and 2018

Background/aim: Hantavirus is a rodent borne zoonosis caused by the members of the virus family Bunyaviridae, genus Hantavirus. In this study, we aimed to determine the role of peripheral blood leukocyte ratio in differential diagnosis of Hantavirus disease. Materials and methods: The medical records of patients at the Düzce University Medical Faculty were examined retrospectively. A total of 20 patients diagnosed with hantavirus infection confirmed by serologic tests were included in the study (Group 1). The other group consisted of 30 patients suspected of hantavirus infection but found negative (Group 2). Demographic, clinical and laboratory characteristics, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and lymphocyte/monocyte (LMR) ratios of both groups were compared. Results: As a result of the istatistics analysis, no difference was found between the groups' age, sex, and clinical complaints except lethargy-weakness (P = 0.004) and diarrhea (P < 0.001). Hemogram analysis showed a significant difference between the groups in terms of leukocyte, hemoglobin, hematocrit, platelet, mean platelet volume (P < 0.05) and PLR (P = 0.001) and LMR (P = 0.003) values from peripheral blood leukocyte ratios. Conclusion: In conclusion, NLR, PLR, and LMR ratios may be useful for clinicians in differential diagnosis of Hantavirus in patients presenting with similar symptoms of Hantavirus disease.

Serum trace element and heavy metal levels in patients with sepsis.

Background and objectives: Sepsis is defined as a life-threatening organ dysfunction syndrome, which occurs when the body's immune response to infection is impaired. The aim of the present study was to investigate serum Iron, Copper, Zinco, Cobalt, Chromium, Selenium, Vanadium, Nickel, Cadmium, and Aliminium levels in patients with sepsis.Materials and methods: This prospective and observational study was conducted at a tertiary care university hospital of Turkey from 2015 to 2016, and comprised patients with sepsis. Serum concentrations of 10 elements were analyzed using inductively coupled plasma mass spectrometry. Analyses were performed at the laboratory of Düzce University Scientific and Technological Research Application and Research Center. A total of 87 participants (52 men, 35 women; average age, 74.11 ± 14.26) were enrolled.Results: When evaluated in terms of trace elements, a significant difference was noted between the sepsis and control groups in terms of the levels of the five elements. Chromium, Iron, Nickel, Copper, and Cadmium levels were significantly higher in the sepsis group.Conclusion: Our study indicated in particular, Iron, Copper, Chromium, Nickel, and Cadmium levels were elevated in patients with sepsis.

Assessment of Patients with Intracerebral Hemorrhage or Hemorrhagic Transformation in the VENOST Study.

INTRODUCTION: Cerebral venous and sinus thrombosis (CVST) may lead to cerebral edema and increased intracranial pressure; besides, ischemic or hemorrhagic lesions may develop. Intracerebral hemorrhages occur in approximately one-third of CVST patients. We assessed and compared the findings of the cerebral hemorrhage (CH) group and the CVST group. MATERIALS AND METHODS: In the VENOST study, medical records of 1,193 patients with CVST, aged over 18 years, were obtained from 35 national stroke centers. Demographic characteristics, clinical symptoms, signs at the admission, radiological findings, etiologic factors, acute and maintenance treatment, and outcome results were reported. The number of involved sinuses or veins, localizations of thrombus, and lesions on CT and MRI scans were recorded. RESULTS: CH was detected in the brain imaging of 241 (21.1%) patients, as hemorrhagic infarction in 198 patients and intracerebral hemorrhage in 43 patients. Gynecologic causes comprised the largest percentage (41.7%) of etiology and risk factors in the CVST group. In the CH group, headache associated with other neurological symptoms was more frequent. These neurological symptoms were epileptic seizures (46.9%), nausea and/or vomiting (36.5%), altered consciousness (36.5%), and focal neurological deficits (33.6%). mRS was ≥3 in 23.1% of the patients in the CH group. DISCUSSION AND CONCLUSION: CVST, an important cause of stroke in the young, should be monitored closely if the patients have additional symptoms of headache, multiple sinus involvement, and CH. Older age and parenchymal lesion, either hemorrhagic infarction or intracerebral hemorrhage, imply poor outcome.

Receptor Activator of Nuclear Factor κ-Β Ligand/Osteoprotegerin Axis in Adults with Hb S/ß-Thalassemia and ß-Thalassemia Trait.

There is not enough data about osteoporosis and the role of receptor activator of nuclear factor κ-Β ligand (RANKL)/serum osteoprotegerin (OPG) system in patients with double heterozygosity for sickle cell disease and ß-thalassemia [Hb S (HBB: c.20A>T)/ß-thal] and ß-thal trait. Aim of the study was to investigate bone mineral densities (BMD) and the role of RANKL/OPG system in these cases. We studied 58 adults with Hb S/ß-thal, 52 adults with ß-thal trait, 34 healthy subjects as a control group. The BMD was determined by dual-energy X-ray absorptiometry (DEXA). Biochemical markers of bone metabolism (serum calcium, phosphorus, alkaline phosphatase, osteocalcin) parameters that affect bone metabolism (serum parathyroid hormone, thyroid-stimulating hormone, 25-hydroxyvitamin D, OPG, soluble RANKL [sRANKL]) were studied. Femoral neck Z-scores of 93.2% for ß-thal trait, 83.0% for Hb S/ß-thal patients were within the expected range. Lumbar spine Z-scores of 89.1% for ß-thal, 90.2% for Hb S/ß-thal patients were above -2.0 SD. Z-scores of the control group were within the expected range. Median serum sRANKL level was 2.80, 4.52, 5.79 pmol/L in Hb S/ß-thal, ß-thal trait, control groups, respectively (p = 0.010). Median serum OPG level was 1.07, 0.86, 0.86 pmol/L in Hb S/ß-thal, ß-thal trait, control groups, respectively (p < 0.001). ß-Thalassemia trait alone is not a risk factor for osteopenia/osteoporosis and osteoporosis does not develop in premenopausal women and men younger than 50 years with Hb S/ß-thal. However, as we determined lower levels of osteocalcin, compensatory decrease of sRANKL with compensatory increase of OPG, more severe osteoporosis may develop in advanced ages in these patient populations.

Behçet's disease as a causative factor of cerebral venous sinus thrombosis: subgroup analysis of data from the VENOST study.

OBJECTIVE: This study was performed to determine the rate of cerebral venous sinus thrombosis (CVST) among cases of Behçet's disease (BD) included in a multicentre study of cerebral venous sinus thrombosis (VENOST). METHODS: VENOST was a retrospective and prospective national multicentre observational study that included 1144 patients with CVST. The patients were classified according to aetiologic factors, time of CVST symptom onset, sinus involvement, treatment approach and prognosis. RESULTS: BD was shown to be a causative factor of CVST in 108 (9.4%) of 1144 patients. The mean age of patients in the BD group was 35.27 years and 68.5% were men, whereas in the non-BD CVST group, the mean age was 40.57 years and 28.3% were men (P < 0.001). Among the aetiologic factors for patients aged 18-36 years, BD was predominant for men, and puerperium was predominant for women. The onset of symptoms in the BD group was consistent with the subacute form. The transverse sinuses were the most common sites of thrombosis, followed by the superior sagittal sinuses. The most common symptom was headache (96.2%), followed by visual field defects (38%). CONCLUSIONS: BD was found in 9.4% of patients in our VENOST series. Patients with BD were younger and showed a male predominance. The functional outcome of CVST in patients with BD was good; only 12% of patients presenting with cranial nerve involvement and altered consciousness at the beginning had a poor outcome (modified Rankin Score ⩾2).

Cerebral Venous Sinus Thrombosis as a Rare Complication of Systemic Lupus Erythematosus: Subgroup Analysis of the VENOST Study.

AIM: Systemic lupus erythematosus (SLE) is an unusual risk factor for cerebral venous sinus thrombosis (CVST). As few CVST patients with SLE have been reported, little is known regarding its frequency as an underlying etiology, clinical characteristics, or long-term outcome. We evaluated a large cohort of CVST patients with SLE in a multicenter study of cerebral venous thrombosis, the VENOST study, and their clinical characteristics. MATERIAL AND METHOD: Among the 1144 CVST patients in the VENOST cohort, patients diagnosed with SLE were studied. Their demographic and clinical characteristics, etiological risk factors, venous involvement status, and outcomes were recorded. RESULTS: In total, 15 (1.31%) of 1144 CVST patients had SLE. The mean age of these patients was 39.9 ± 12.1 years and 13 (86.7%) were female. Presenting symptoms included headache (73.3%), visual field defects (40.0%), and altered consciousness (26.7%). The main sinuses involved were the transverse (60.0%), sagittal (40.0%), and sigmoid (20.0%) sinuses. Parenchymal involvement was not seen in 73.3% of the patients. On the modified Rankin scale, 92.9% of the patients scored 0-1 at the 1-month follow-up and 90.9% scored 0-1 at the 1-year follow-up. CONCLUSIONS: SLE was found in 1.31% of the CVST patients, most frequently in young women. Headache was the most common symptom and the CVST onset was chronic in the majority of cases. The patient outcomes were favorable. CVST should be suspected in SLE patients, even in those with isolated chronic headache symptoms with or without other neurological findings.

Erythropoietin may attenuate lung inflammation in a rat model of meconium aspiration syndrome.

BACKGROUND: Inflammation is believed to play a key role in the pathophysiology of meconium aspiration syndrome (MAS). PURPOSE OF THE STUDY: The objective was to determine whether the recombinant human Erythropoietin (rhEPO) pretreatment could attenuate meconium-induced inflammation. MATERIALS AND METHODS: In this study, 24 ventilated adult male rats were studied to examine the effects of recombinant human EPO (rhEPO) on meconium-induced inflammation. Seventeen rats were instilled with human meconium (1.5 mL/kg, 65 mg/mL) intratracheally and ventilated for 3 hours. rhEPO (1000 U/kg) (n = 9) or saline (n = 8) was given to the animals. Seven rats that were ventilated and not instilled with meconium served as a sham-controlled group. Analysis of the blood gases, interleukin (IL)-1ß, IL-6, IL-8, and tumor necrosis factor (TNF)-α in blood and bronchoalveolar lavage (BAL) fluid samples, and lung tissue myeloperoxidase levels were performed. RESULTS: Intrapulmonary instillation of meconium resulted in the increase of TNF-α (p = 0.005 and p < 0.001, respectively) and IL-8 concentrations (p < 0.001 and p < 0.001, respectively) in BAL fluid in the EPO + meconium and saline + meconium groups compared with the sham-controlled group. rhEPO pretreatment prevented the increase of BAL fluid IL-1ß, IL-6, and IL-8 levels (p < 0.001, p = 0.021, and p = 0.005, respectively), and serum IL-6 levels (p = 0.036). CONCLUSION: rhEPO pretreatment is associated with improved BAL fluid and serum cytokine levels. Pretreatment with rhEPO might reduce the risk of developing of meconium-induced derangements.

Is There a Relationship Between Paratracheal Air Cysts and Upper Lobe Fibrosis?

OBJECTIVE: The purpose of this study was to determine the characteristics of paratracheal air cysts (PACs) and their relationship with upper lobe pulmonary fibrosis. MATERIALS AND METHODS: The routine thoracic computed tomography scans of 3549 patients carried out between January 2014 and April 2015 were retrospectively evaluated. The presence, location, structural characteristics (uniloculated or multiloculated), number of cysts, and anterior-posterior and transverse dimensions of the PAC and its communication with the tracheal lumen were evaluated. The presence of upper lobe fibrosis, emphysema, and bronchiectasis was also evaluated. The relationship between upper lobe fibrosis, emphysema, bronchiectasis, and the presence of paratracheal cysts was evaluated in all patients. An equal number of randomized patients with no paratracheal cysts were selected as a control group. RESULTS: A total of 190 PAC cases were diagnosed, with a prevalence rate of 5.35%: 146 (76.8%) of the cases were men, 44 (23.2%) were female, and the mean (SD) age was 53.79 (16.64) years (range, 12-89 years). The control group included 105 men (57.4%) and 78 women (42.6%), and the mean (SD) age was 53.87 (16.65) years (range, 13-87 years). The groups were similar in terms of age (P = 0.876), whereas the proportion of men in the PAC group was significantly higher (P < 0.001). Most of the PACs were located on the right side (n = 188, 98.9%). The incidence of fibrosis in the paratracheal cyst group was 45.8% (n = 87) compared with 19.5% (n = 37) in the control group; this difference was statistically significant (P < 0.001). The prevalence rates of emphysema in the cyst group and the control group were 29.5% (n = 56) and 11.6% (n = 22), respectively, and the difference was statistically significant (P < 0.001). When the groups were compared regarding bronchiectasis (scar and non-scar related), the rate of bronchiectasis in the paratracheal cyst group was 17.9% (n = 34), compared with 3.7% (n = 7) in the control group; this difference was statistically significant (P < 0.001). CONCLUSIONS: Paratracheal air cysts are relatively common, but the etiology is still unclear. We detected increased rates of cyst formation that may result from the traction effect on the tracheal wall in the presence of upper lobe fibrosis.

Comparison of selective head cooling versus whole-body cooling.

BACKGROUND: This study compared selective head cooling (SHC) and whole-body cooling (WBC) in newborns with hypoxic-ischemic encephalopathy (HIE). METHODS: We conducted a prospective randomized small-scale pilot study in newborns with HIE, born after >35 weeks of gestation. The patients were randomly assigned to receive SHC or WBC. RESULTS: The SHC group consisted of 17 patients, and the WBC group, 12 patients. There was no significant difference in adverse effects related to cooling therapy between the two groups. During the 12 month study period, seven patients in the SHC group and four in the WBC group died, but the difference was not significant (P = 0.667). Among the patients alive at 12 months after treatment, six in the SHC group and four in the WBC group had severe disabilities; the difference was not significant (P = 0.671). When the composite outcome of death or severe disability was evaluated, the difference between the SHC group (77%, n = 13) and the WBC group (67%, n = 8) was not significant (P = 0.562). Moreover, the number of survivors without disability at 12 months after treatment did not differ significantly between the SHC group (n = 3) and the WBC group (n = 4; P = 0.614). CONCLUSIONS: There were no significant differences in adverse effects, 12 month neuromotor development, or mortality rate between SHC and WBC in newborns with HIE, born after >35 weeks of gestation.

Evaluation of poisoning deaths in the Cukurova Region, Turkey, 2007-2011.

Complications of substances detected in poisoning deaths are important in order to observe changes in poisoning patterns and to monitor effects of preventive work. The aim of the present study was to describe the characteristics of substances investigated and detected in poisoning deaths by Adana Group Authority of the Council of Forensic Medicine, Department of Forensic Chemistry, Cukurova, Turkey, between 2007 and 2011 retrospectively. A total of 7681 examinations were performed, of which, 7% (n = 564) determined positive for at least one compound investigated. Ages of the cases ranged from 1 to 97 years (mean ± SD: 36.10 ±19.16). Carbon monoxide (CO) poisonings were found most frequently with an incidence of 27.0%, followed by prescription medications with 25.0%. Illegal drug poisonings were present in 20.0% of blood and urine samples analyzed. Pesticides, mostly endosulfan, were found in 13.0% of the 564 cases investigated. In the blood samples analyzed, methyl and ethyl alcohol were detected in 14.0% and volatile substances in 1.0%. Overall, this study has managed to contribute substantial additional information regarding the epidemiology of poisoning in Cukurova region, Southern Turkey. The results confirm other epidemiological data that indicate CO as the major cause of poisoning deaths in Turkey.

Phenotypic features of chronic migraine.

BACKGROUND: Chronic migraine is a disabling, under-recognized, and undertreated disorder that increases health burdens. The aim of this study was to evaluate phenotypic features and the relevance of accompanying symptoms of migraine attacks in chronic migraine. METHOD: This study was conducted as part of an ongoing Turkish Headache Database Study investigating the clinical characteristics and outcomes of headache syndromes in the Turkish population. The electronic database was examined retrospectively, and 835 patients with chronic migraine were included. RESULTS: Patient group consisted of 710 women and 125 men (85 and 15 %, respectively). Mean patient age was 36.8 ± 13.5 years, median value of migraine onset was 60 months (18-120), median headache frequency was 25 days per month (16-30), median of attack duration was 12 h (4-24), and median of intensity was eight (7-9). Increasing headache days per month were inversely related with the presence of nausea, vomiting, phonophobia, and photophobia. Longer duration of headache (months) and higher visual analog scale (VAS) for headache intensity were associated with all accompanying symptoms. Phonophobia, nausea, photophobia, and vomiting were the most frequent accompanying symptoms (experienced by 80.2, 77.6, 71.2, and 40.9 % of patients, respectively). Osmophobia was also frequent in chronic migraine patients (53.4 %) and was closely associated with other accompanying symptoms. Vertigo and dizziness were observed less frequently, and they were not associated with accompanying symptoms. CONCLUSION: Phenotype of chronic migraine may be associated with the course of chronification. Duration of illness and attack intensity were closely related with the presence of accompanying symptoms, although headache frequency was found to be inversely related to the presence of accompanying symptoms. Osmophobia was also a frequent symptom and was closely related with other accompanied symptoms, unlike vertigo and dizziness. Inclusion of osmophobia into the diagnostic criteria might improve accurate diagnosis of chronic migraine.

Radiobasilic Versus Brachiobasilic Transposition on the Upper Arm to Avoid Steal Syndrome.

BACKGROUND: Although the proximal radial artery has been reported as an alternative inflow to prevent steal syndrome, brachiobasilic fistula has been reported to be associated with steal syndrome in 10-20% of cases. We aimed to compare proximal radiobasilic arteriovenous fistula (AVF) with brachiobasilic AVFs on the upper arm in terms of steal syndrome and outcomes. MATERIAL AND METHODS: We used our institutional operative record database to identify 94 patients in whom brachiobasilic AVF (n=40) and radiobasilic AVF (n=54) were placed between January 2009 and December 2013. Postoperative complications such as steal syndrome, venous hypertension, and aneurysm were recorded. RESULTS: Steal syndrome was determined to occur less frequently in the radiobasilic AVF group (0% vs. 10%, P=0.03). The rates of other complications (bleeding, aneurysm, venous hypertension) between the 2 groups were similar, as were the patency rates. CONCLUSIONS: Radiobasilic AVF was effective in reducing steal syndrome, with similar early and late outcomes.

Lack of nephrotoxicity of gadopentetate dimeglumine-enhanced non-vascular MRI and MRI without contrast agent in patients at high-risk for acute kidney injury.

BACKGROUND: Gadolinium chelates (GCs) have been traditionally considered as non-nephrotoxic magnetic resonance imaging (MRI) contrast materials. However, it has been suggested in some recent articles that GCs may have a nephrotoxic potential, but most of these reports are retrospective. However, the evaluated contrast agents, their doses, and the tests used to determine the kidney function were not consistent across studies. We aimed to investigate the effect of magnetic field and an MRI contrast agent, gadopentetate dimeglumine (GD), on renal functions in patients at high risk for acute kidney injury (AKI). MATERIAL AND METHODS: We designed a prospective case-control study with 2 age- and sex-matched groups of patients at high-risk for AKI (n=72 for each group). Patients in Group 1 received a fixed dose of (0.2 mmol/kg) GD-enhanced non-vascular MRI and patients in Group 2 received MRI without GD. Before the MRI and at 6, 24, 72, and 168 hours after the MRI, biochemical tests, estimated glomerular filtration rate (eGFR), albumin/creatinine ratio in spot urine, and early AKI biomarkers (cystatin C, N-Acetyl-Glucosaminidase [NAG], Neutrophil gelatinase-associated lipocalin [NGAL]) were measured. RESULTS: Serum creatinine, albumin/creatinine ratio, and eGFR were not different between Group 1 and 2 (p>0.05). There were no significant changes in renal function tests and AKI biomarkers (∆serum creatinine, ∆albumin/creatinine ratio, ∆GFR, ∆cystatin C, ∆NAG, and ∆NGAL) for either groups 6, 24, 72, and 168 hours after the procedures (p>0.05). CONCLUSIONS: MRI without contrast agent and non-vascular contrast-enhanced (GD, 0.2 mmol/kg) MRI are not nephrotoxic procedures for patients at high risk for AKI.

[Determination of hepatitis C virus genotype distribution in Mersin province, Turkey]. / Mersin ilinde hepatit C virusu genotip dagiliminin belirlenmesi.

Hepatitis C virus (HCV) is a member of the Flaviviridae family and the RNA genome e x hibit high genetic heterogeneity. Six major genotypes were phylogenetically determined and each genotype contains different subtypes. The distribution of HCV genotypes varies geographically throughout the world. Determination of viral genotype has great importance in the selection of antiviral therapy, treatment duration and monitoring the response to treatment. The aim of this study was to determine the distribution of HCV genotypes in Mersin province located at the Southern part of Turkey. A total of 236 patients (137 females, 99 males; mean age: 53.28 ± 14.99 years) with chronic HCV infection who were admitted to Mersin University Hospital Microbiology Laboratory during March 2010-May 2012 period were included in the study. The patients were anti-HCV (ELISA; Abbott Laboratories, USA) and HCV-RNA (Cobas TaqMan 48, Roche Diagnostic, USA) positive. HCV genotype analysis was determined by using a commercial LiPA kit (Line Probe Assay; AMPLIQUALITY HCV-TS; AB Analitica, Italy) based on the reverse hybridization of amplification products of viral 5'-UTR region. Out of the 236 patients, genotype 1b was observed in 84.7% (n= 200), genotype 3a in 4.2% (n= 10), genotype 1 in 3.8% (n= 9), genotype 1a/1b in 2.1% (n= 5), genotype 4a in 2% (n= 2), genotype 1a in 1.7% (n= 4), genotype 2b in 1.3% (n= 3), genotype 2 in 0.4% (n= 1), genotype 2a/2c in 0.4% (n= 1) and genotype 6 in 0.4% (n= 1). In the cases infected with genotype 1b, statistically significant differences were detected between gender distribution with the mean serum ALT (46.14 IU/L in females, 63.9 IU/L in males; p= 0.029) and HCV-RNA (634 x 103 IU/L in females, 20 x 105 IU/L in males; p= 0.005) levels. This was the first study that reflected the distribution of HCV genotypes in southern Turkey region. Genotype 1b, associated with poor prognosis and which had the highest prevalence in Turkey, was also determined as the most common genotype with a rate of 84.7% in our region. In addition, low rates of genotype 1a, 2b, 3a and 4a which were identified with low frequency in our country and newly introduced genotype 6 were also demonstrated.

Is Selective Head Cooling Combined with Whole-Body Cooling the Most Effective Hypothermia Method for Neonatal Hypoxic-Ischemic Encephalopathy?

This study aimed to compare combined hypothermia (CH) to the 2 classical therapeutic hypothermia (TH) methods selective head cooling (SHC) and whole-body cooling (WBC). This retrospective cohort study included neonates who underwent CH, SHC, and WBC between 2012 and 2020. Mean rectal temperature was maintained at 33.5 ± 0.5°C by cooling the head and the body in the CH group, at 34.5 ± 0.5°C by cooling the head in the SHC group, and at 33.5 ± 0.5°C by cooling the body in the WBC group. The groups were compared in terms of side effects, magnetic resonance imaging (MRI) scores, and status at discharge. The study included 60 neonates in the CH group, 112 in the WBC group, and 27 in the SHC group. There was no significant difference in side effects between the groups (p > 0.05). There was no significant difference in brain MRI scores between the groups (p > 0.05); however, gray matter, white matter, and total MRI scores in the CH group were lower than in the WBC group. Duration of hospitalization was shorter in the CH group than in the other two groups (p = 0.022). CH was not associated with more side effects than the two classical TH methods. In addition, some of these findings suggest that CH might result in better clinical outcome than the two classical TH methods.

The Psychosocial Impact of Chronic Facial Dermatoses in Adults.

INTRODUCTION: Skin diseases have negative psychological and social consequences, especially when they are chronic and affect a visible area of the body, such as the face. OBJECTIVES: The purpose of this study is to investigate and compare the psychosocial impact of three common chronic dermatoses of the face: acne, rosacea, and seborrheic dermatitis. METHODS: The Dermatology Life Quality Index (DLQI), Hospital Anxiety and Depression Scale (HADS), and Social Appearance Anxiety Scale (SAAS) were used to compare acne, rosacea, and seborrheic dermatitis patients and healthy controls. The relationships between DLQI, HADS, and SAAS results were investigated, as well as their associations with disease duration and severity. RESULTS: The study included 166 acne patients, 134 rosacea patients, 120 seborrheic dermatitis patients, and 124 controls. The patient groups had significantly higher DLQI, HADS, and SAAS scores than the control group. Rosacea patients had the highest DLQI and SAAS scores, as well as the highest anxiety prevalence. Patients with seborrheic dermatitis had the highest rate of depression. The DLQI, HADS, and SAAS results were moderately correlated with each other, but their relationship with disease duration and severity was insignificant or weak at best. CONCLUSIONS: Chronic facial dermatoses have a detrimental impact on mood and quality of life. Although patients with acne, rosacea, and seborrheic dermatitis have distinct lesions, the outcomes in terms of quality of life, anxiety, and depression are largely similar.

Quercetin- and caffeic acid-functionalized chitosan-capped colloidal silver nanoparticles: one-pot synthesis, characterization, and anticancer and antibacterial activities.

The presented study comprises the one-pot synthesis and the characterization of quercetin- and caffeic acid-functionalized chitosan-capped colloidal silver nanoparticles (Ch/Q- and Ch/CA-Ag NPs), and their antibacterial and anticancer activities. The formation of Ch/Q- and Ch/CA-Ag NPs has been confirmed by ultraviolet-visible (UV-vis) spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, and transmission electron microscopy (TEM). The characteristic surface plasmon resonance (SPR) absorption band has been found at 417 and 424 nm for Ch/Q- and Ch/CA-Ag NPs, respectively. The formation of a chitosan shell comprising quercetin and caffeic acid, which surround the colloidal core Ag NPs, was confirmed by UV-vis, and FTIR analyses, and monitored by TEM microscopy. The size of nanoparticles has been determined as 11.2 and 10.3 nm for Ch/Q- and Ch/CA-Ag, respectively. The anticancer activity of Ch/Q- and Ch/CA-Ag NPs has been evaluated against U-118 MG (human glioblastoma) and ARPE-19 (human retinal pigment epithelium) cells. Both NPs showed anticancer activity, but Ch/Q-Ag NPs seemed to be more effective on cancer cell lines (U-118 MG) in comparison to healthy ones (ARPE-19). Furthermore, the antibacterial activity of Ch/Q- and Ch/CA-Ag NPs against Gram-negative (P. aeruginosa and E. coli) and Gram-positive (S. aureus and S. epidermidis) bacteria was determined, and dose-dependent antibacterial effects were found.
