Increased accumulation of the advanced glycation endproduct Ne(carboxymethyl) lysine in the intramyocardial vasculature in patients with epicarditis.

Advanced glycation end-products (AGEs) are implicated in the pathogenesis of vascular disease. In previous studies we have found increased deposition of N(e)-(carboxymethyl)lysine (CML) in intramyocardial vasculature in the heart in acute myocardial infarction and myocarditis. It is known that the process of inflammation plays a role in the formation of AGEs. In this study we have explored the presence of CML (a major AGE) in the heart of patients with epicarditis using a monoclonal anti-CML antibody. Nine patients with epicarditis (n = 9) died and their hearts were used for this study, control were hearts from patients who died from conditions unrelated to heart disease and without signs of myocarditis or epicarditis CML deposition and complement were significantly increased in patients with epicarditis compared to control hearts. Thus epicarditis increases CML depositions in the intramyocardial vasculature.

Frail patients who fall and their risk on major bleeding and intracranial haemorrhage. Outcomes from the Fall and Syncope Registry.

BACKGROUND: Major bleeding, and intracranial bleeding specifically, are severe complications related to the use of anticoagulation. To what extent the risk for major bleeding is elevated among frail older people is not well known because they are underrepresented in the randomized clinical trials (RCTs). This study investigates the risk for major bleeding (MB) and intra cranial haemorrhage (ICH) in frail older people who fall. METHODS: All patients 65 years and older visiting the Fall and Syncope Clinic, between November 2011 and January 2020, and underwent a MRI of the brain were eligible. Frailty was assessed with a Frailty Index, based on the accumulation of deficits model. Cerebral small vessel disease was described and evaluated as proposed in the position paper of Wardlaw and colleagues in 2013. RESULTS: 479 patients were included in this analysis. Mean follow-up was 7 years per patient (ranging from 1 month to 8 years and 5 months). 368 patients (77%) were frail. A total of 81 patients used oral anticoagulation (OAC). 17 extracranial MB of which 3 were traumatic and 14 gastrointestinal, and 16 ICH occurred. There was a total of 603.4 treatment years with OAC, and 8 MBs occurred among patients on OAC (bleeding rate 1.32 per 100 treatment years), of which 2 ICHs (bleeding rate 0.33 per 100 treatment years). The risk for extracranial MB was increased by the use of antiplatelet agents (APA) (adjusted OR 6.9, CI 95% 1.2-38.3), and by the use of OAC (adjusted OR 9.8, CI 95% 1.7-56.1). The risk for ICH was only heightened by white matter hyperintensities (WMH) (adjusted OR 3.8, CI 95% 1.0-13.4). The use of APA (adjusted OR 0.9, CI 95% 0.3-3.3) or OAC (adjusted OR 0.6, CI 95% 0.1-3.3) did not elevate the risk for ICH. CONCLUSION: In contrast to common belief, frail patients on OAC with repeated falls show a comparable bleeding rate as in the large RCTs, and the use of OAC did not increase the risk for ICH. However, the number of MBs was low, and of ICHs very low, despite extensive follow-up in this registry.

Coexistent subclinical hypothyroidism is associated with an increased risk of new cardiovascular events in rheumatoid arthritis: an explorative study.

Objective: Autoimmune thyroid disease often coexists with rheumatoid arthritis (RA) and is associated with elevated cardiovascular (CV) risk. However, studies in RA patients are scarce. Our aim was to investigate whether autoimmune thyroid disease increases the risk of new cardiovascular disease (CVD) in RA.Method: Thyroid-stimulating hormone (TSH) and serum free thyroxine (FT4) were assessed in 323 RA patients participating in an ongoing prospective cohort study designed to assess CV risk factors, morbidity, and mortality. Cox proportional hazard models were used to calculate hazard ratios (HRs) for new CVD and adjusted for age, gender, smoking, prevalent CVD, thyroxine replacement therapy, and RA duration.Results: Of the 323 participants, 65.3% were female, and mean ± sd age was 63 ± 7 years. At baseline, 8.1% were hypothyroid (n = 26, 16 clinical, 10 subclinical), 6.8% hyperthyroid (n = 22, 13 clinical, 9 subclinical), and 85.1% (n = 275) euthyroid. A new CV event developed in 94 patients (29.1%) during follow-up. Compared to euthyroid patients, the HR adjusted for age, gender, and prevalent CVD was 2.83 [95% confidence interval (CI) 1.13-7.09; p = 0.026] for subclinical hypothyroidism. Further adjustment for smoking, thyroxine replacement therapy, and RA duration resulted in an HR of 3.0 (95% CI 1.19-7.54; p = 0.02) for CV events in patients with subclinical hypothyroidism.Conclusion: There was no difference in CVD between RA patients with hypothyroidism and hyperthyroidism versus euthyroid patients. Coexistence of subclinical hypothyroidism with RA is associated with a higher occurrence of new CV events. Treatment trials are needed to determine whether thyroxine supplementation can further improve CV outcome in these patients.

Accuracy of an algorithm to identify rheumatoid arthritis in the Longitudinal Ageing Study Amsterdam population: a validation study.

Objective: In view of global ageing and the scarcity of knowledge about disease determinants in older individuals with rheumatoid arthritis (RA), an algorithm with optimal diagnostic accuracy was developed to identify RA patients in the Longitudinal Ageing Study Amsterdam (LASA).Method: Four case ascertainment algorithms were constructed and assessed for validity in LASA, an ongoing cohort study (≥ 55 years) representing the general older population of the Netherlands. Data sources used to identify the diagnosis RA were: self-reported morbidity, specialist diagnosis, and medication. A validation subsample of LASA participants was taken to verify RA diagnosis by a standard procedure using a checklist.Results: Data from 272/300 (91%) participants were verified. Four algorithms were developed: 'treatment', 'diagnosis', 'treatment or diagnosis', and 'treatment and diagnosis'. The algorithm 'treatment and diagnosis' showed the best measurement properties: specificity 100%, positive predictive value 100%, and area under the receiver operating characteristics curve 0.72. Applying this algorithm in the LASA sample (mean age 71 years) revealed a prevalence of RA of 1.0% (19/1908 participants).Conclusion: An algorithm for RA identification in the LASA population was developed, with high diagnostic accuracy. It provides an accurate tool to identify older adults with RA in LASA and, after validation, may be applicable in other large population-based studies.

The effect of anti-TNF treatment on body composition and insulin resistance in patients with rheumatoid arthritis.

Given the link between systemic inflammation, body composition and insulin resistance (IR), anti-inflammatory therapy may improve IR and body composition in inflammatory joint diseases. This study assesses the IR and beta cell function in rheumatoid arthritis (RA) patients with active disease compared to osteoarthritis (OA) patients and investigates the effect of anti-TNF treatment on IR, beta cell function and body composition in RA. 28 Consecutive RA patients starting anti-TNF treatment (adalimumab), and 28 age, and sex-matched patients with OA were followed for 6 months. Exclusion criteria were use of statins, corticosteroids, and cardiovascular or endocrine co-morbidity. Pancreatic beta cell function and IR, using the homeostasis model assessment (HOMA2), and body composition, using dual-energy X-ray absorptiometry (DXA) were measured at baseline and 6 months. At baseline, IR [1.5 (1.1-1.8) vs. 0.7 (0.6-0.9), 100/%S] and beta cell function (133% vs. 102%) were significantly (p < 0.05) higher in RA patients with active disease as compared to OA patients. After 6 months of anti-TNF treatment, IR [1.5 (1.1-1.8) to 1.4 (1.1-1.7), p = 0.17] slightly improved and beta cell function [133% (115-151) to 118% (109-130), p <0.05] significantly improved. Improvement in IR and beta cell function was most pronounced in RA patients with highest decrease in CRP and ESR. Our observations indicate that IR and increased beta cell function are more common in RA patients with active disease. Anti-TNF reduced IR and beta cell function especially in RA patients with highest decrease in systemic inflammation and this effect was not explained by changes in body composition.

A Rare Case of Flexor Tenosynovitis Due to Tuberculosis in Hand and Wrist: a Case Report.

Tuberculosis (TB) is still a worldwide problem. We present a case of flexor tenosynovitis due to tuberculosis in the hand and wrist. A 42-year-old man presented to the outpatient clinic with a 2-year history of a slowly growing mass over the volar aspect of the left wrist. His MRI showed multiple rice bodies in the wrist and hand. An open biopsy was performed. Pathology specimens showed granulomatous lesions with central necrosis. The purified protein derivative (PPD) test was positive. In this case, granulomatous lesions with central necrosis, rice bodies, and positive PPD test confirmed the diagnosis of TB in the wrist and hand. There was no other concurrent evidence of TB elsewhere. Antituberculosis chemotherapy was commenced. Tuberculous tenosynovitis of the wrist and hand is very rare. The tuberculous tenosynovitis should be kept in mind as an infectious agent when patients are presenting with atypical clinical. Key words: tuberculosis, rice bodies, flexor tenosynovitis, wrist, hand.

In-silico Analysis of Mt-CO1 Gene of Taenia Hydatigena Sheep Isolates.

Taenia hydatigena is a tapeworm that affects herbivores in different regions of the world. Cysticercus tenuicollis (larvae of T. hydatigena), is prevalent in ruminants and pigs. In the current study, phylogenetic analysis of the published mt-CO1 gene of C. tenuicollis sheep isolates was analyzed using in-silico method and vertical and horizontal transmission at the global level by using a meta-analysis approach. A total of 82 mt-CO1 nucleotide sequences (339 bp) of C. tenuicollis sheep isolates from the NCBI database (Italy -Sardinia-, Iran, Palestine, Iraq, Finland, India and China) were used to investigate haplotype and genetic relationships. Tajima's D (-2,2984) value was negative for the mt-CO1 sequences signifying the population expansion and/or purifying selection. The highly negative Fu's Fs (-60,528) values determined for the sequences reflecting the existence of uncommon haplotypes. The mt-CO1 of C. tenuicollis haplotype network had 47 haplotypes arranged within a star-like configuration with a main haplotype, which encompassed 25.6 % of the total isolates. In the mt-CO1 haplotype network analyzed, there were 80.5 % unique single haplotype and highest ratio was observed in C. tenuicollis from sheep originating from Iran, followed by Sardinia, Palestine and Finland. If the current condition continues, genetic differences in T. hydatigena will be able to rise, and possible new strains and/or genotypes that may influence the host adaptation and life cycle of the parasite may emerge.

Demographics of Cystic Echinococcosis Patients Treated Surgically in Lahore, Pakistan: A Single Centre Study from 2007 - 2018.

Cystic echinococcosis (CE) is a zoonotic disease caused by the larval stage of Echinococcus granulosus tapeworms. These parasites have a worldwide geographic distribution and pose a serious threat to livestock industry as well as human health in the endemic areas. CE is widely distributed in Pakistan. However, very few reports are available related to the regional transmission of E. granulosus. A retrospective analysis was conducted of surgically confirmed CE patients who were treated at Shoukat Khanum Memorial Cancer Hospital and Research Centre in Lahore, Punjab Province, Pakistan from 2007 - 2018. In total, 536 CE patients were evaluated during the study period. Cases originated from the provinces of Khyber Pakhtunkhwa (n=336), Punjab (n=147), Baluchistan (n=18), Sindh (n=3), Islamabad (n=2), Gilgit Baltistan (n=1), and Azad Jammu and Kashmir (n=1). An additional 28 cases were from Afghanistan. The highest number of CE cases was reported in 2013 (n=90). Females made up a larger proportion of cases (n=310; 57.8 %) than males (n=226; 42.2 %). Most patients were members of the Pashtun (n=197; 36.7 %), Hindku (n=142; 26.5 %), and Punjabi (n=118; 22.0 %) ethnic groups. The largest number of cysts was obtained from the liver (137/536; 25.6 %). This study showed that CE is likely present throughout Pakistan. In order to control the disease, a comprehensive control program and regional surveillance are needed.

Evaluation of the Effectiveness of Liquid Platelet-Rich Fibrin and Deproteinized Bovine Bone Mineral Mixture on Newly Formed Bone in Maxillary Sinus Augmentation: A Split-Mouth, Histomorphometric Study.

OBJECTIVE: We aimed to investigate the effectiveness of the liquid PRF-DBBM mixture on new bone formation in maxillary sinus augmentation. MATERIAL AND METHODS: Seven patients requiring two-stage bilateral maxillary sinus augmentation were included in the study. The patients were selected according to the criteria of having an alveolar bone height of at least 2 mm in the atrophic region. The elevated sinus cavities were randomly grafted with DBBM + liquid PRF (test) or DBBM alone (control) in a split-mouth design. Bone samples were collected during implant surgery with a trephine bur for histomorphometric evaluation after 4 months. RESULTS: In the control group, the newly formed bone was 39.49%, the mature bone was 15.66%, the residual graft was 15.62%, and the fibrous tissue ratio 28.59%, while in the test group, the newly formed bone (NFB) was 45.95%, the mature bone was 14.40%, the residual graft was 10.32%, and the fibrous tissue was 29.31%. No statistically significant difference was found between the groups in terms of the parameters studied (p > 0.05). The mean osteocalcin score in the control group was 2.70 ± 0.39, while it was 2.81 ± 0.36 in the test group. There was no statistically significant difference between the averages of osteocalcin scores of the groups (p > 0.05). CONCLUSION: The results of our study showed that DBBM is a reliable graft material for maxillary sinus augmentation even in the early period. Combining of DBBM with liquid-PRF contributed to new bone formation over a four-month period, but this contribution was not statistically significant.

Preliminary Evidence for the Occurrence of ß-tubulin Isotype 3 Polymorphisms in Fasciola Hepatica Isolates in Cattle and Sheep in Turkey.

Fasciolosis caused by Fasciola hepatica is a common parasitic disease of livestock especially sheep and cattle. In this study molecular characterization of ß-tubulin isotype 3 gene in Fasciola hepatica isolates from cattle and sheep in Turkey was carried out. For this purpose a total of 80 adult Fasciola hepatica isolates were collected from 20 sheep and 20 cattle in Kayseri and Erzurum provinces. PCR-RFLP was performed on ß-tubulin isotype 3 gene and MboII revealed two fragments of approximately 350 bp and 390 bp, whereas HphI enzyme yielded 210, 340 and 540 bp bands, HindII yielded 380 and 450 bp bands in all samples. A total of 80 isolates were tested by SSCP and all of them presented the same band profiles. Six samples (4 sheep and 2 cattle) were randomly selected and DNA sequence of a 935 bp coding fragment of ß-tubulin isotype 3 was performed. Sheep samples were more polymorphic than the cattle. This ß-tubulin isotype 3 gene polymorphism of F.hepatica isolates from sheep and cattle of two distinct geographical areas of Turkey have been investigated for the first time.

Low vitamin D levels are not a contributing factor to higher prevalence of depressive symptoms in people with Type 2 diabetes mellitus: the Hoorn study.

AIM: To test whether a low serum 25-hydroxyvitamin D level explains the greater prevalence of depression among people with Type 2 diabetes. METHODS: We performed a cross-sectional analysis of 527 people, aged 60-87 years, who participated in a population-based cohort study. Type 2 diabetes, impaired glucose tolerance, impaired fasting glucose and normal glucose tolerance were defined according to the 2006 WHO criteria. The Centre for Epidemiologic Studies Depression questionnaire was administered, using a cut-off score of ≥ 16 to determine clinically relevant depressive symptoms. RESULTS: Logistic regression analysis confirmed that women with impaired glucose tolerance/impaired fasting glucose and people with Type 2 diabetes did have a higher risk of depressive symptoms [unadjusted odds ratios 3.66 (95% CI 1.59 to 8.43) and 3.04 (95% CI 1.57 to 5.88), respectively], compared with people with normal glucose tolerance. Serum 25-hydroxyvitamin D level was not a mediating factor in the association between impaired glucose tolerance/impaired fasting glucose or Type 2 diabetes and depressive symptoms [unstandardized indirect effect 0.001 (95% CI -0.063 to 0.079) and 0.004 (95% CI -0.025 to 0.094), respectively]. CONCLUSIONS: The study found no evidence that low vitamin D levels are a contributing factor to higher depression scores in people with Type 2 diabetes.

Vitamin D status and health-related quality of life in patients with Type 2 diabetes.

AIMS: To test whether vitamin D status was associated with health-related quality of life in people with Type 2 diabetes mellitus. METHODS: Demographic and clinical characteristics, including health-related quality of life scores, were obtained from 241 adult patients with Type 2 diabetes managed with oral hypoglycaemic agents. Health-related quality of life was assessed using the Short-Form 36 Health Survey. Multiple logistic regression analysis was used to investigate the association between vitamin D status and health-related quality of life, with adjustment for confounders. RESULTS: The mean age of the patients included in the study was 67 ± 8 years. Their mean HbA1c concentration was 52 ± 8 mmol/mol (6.9 ± 0.7%) and their mean serum 25-hydroxyvitamin D concentration was 59 ± 23 nmol/l. Vitamin D deficiency (serum 25-hydroxyvitamin D < 50 nmol/l) was present in 38% of patients. No significant associations were found between vitamin D status and health-related quality of life. CONCLUSIONS: Vitamin D status was not associated with health-related quality of life in patients with Type 2 diabetes. This could be explained by the relatively high serum 25-hydroxyvitamin D concentration, good glycaemic control and relatively good health-related quality of life of all patients. A prospective study among patients with vitamin D deficiency and poor glycaemic control would be interesting for future research.

Vitamin D status is associated with skin autofluorescence in patients with type 2 diabetes mellitus: a preliminary report.

BACKGROUND: Skin autofluorescence is a non-invasive measurement of advanced glycation end products (AGE), which are suggested to be one of the major agents in the pathogenesis and progression of diabetes related cardiovascular complications. Recently, low vitamin D status has been linked to the progression of type 2 diabetes mellitus (T2DM) and cardiovascular disease. The aim of this study is to investigate the association between vitamin D status and skin autofluorescence in patients with T2DM. METHODS: In this preliminary report skin autofluorescence was measured non-invasively with an AGE-reader in 245 patients with T2DM treated with lifestyle advice, metformin and/or sulphonylurea-derivatives. All patients were randomly assigned to receive either vitamin D 50,000 IU/month or placebo for 6 months. RESULTS: Skin autofluorescence was significantly higher in patients with a serum 25(OH)D < 50 nmol/l compared to patients with a serum 25(OH)D > 75 nmol/l (2.81 versus 2.41; p < 0.001). Mean serum 25(OH)D was 60.3 ± 23.4 nmol/l and was independently associated with skin autofluorescence (ß -0.006; p < 0.001). Mean vitamin D increased from 60.8 to 103.6 nmol/l in the intervention group, however no effect was seen on accumulation of skin AGEs after 6 months compared to placebo. CONCLUSIONS: Vitamin D status is independently associated with skin auto fluorescence in patients with well-controlled T2DM. No effect was seen on the amount of skin AGEs after a short period of 6 months vitamin D supplementation. Further research with longer follow-up and measurement of circulating advanced glycation end products is needed to elucidate the causality of the association.

Advanced glycation end products (AGEs) and the soluble receptor for AGE (sRAGE) in patients with type 1 diabetes and coeliac disease.

BACKGROUND AND AIMS: Advanced glycation end (AGE) products play a role in the progression of diabetic complications. Gluten-free diet (GFD) might affect AGE levels in patients who adhere to a GFD because of coeliac disease (CD). The aim of our study was to compare skin AGE levels and soluble receptor AGE levels (sRAGE) in patients with type 1 diabetes (T1DM) with (T1DM + CD) and without CD (T1DM - CD) and healthy controls. METHODS AND RESULTS: We recruited 25 T1DM + CD and 25 T1DM - CD patients, matched for age, gender, diabetes duration, and glycaemic control alongside 25 healthy controls. We collected demographic, clinical and biochemical characteristics, including skin autofluorescence (AF), sRAGE and hs-CRP levels. The duration of T1DM in patients was 30 ± 14 (+CD) and 29 ± 14 years (-CD), whereas CD duration in T1DM + CD patients was 14 ± 10 years. Skin AF levels in T1DM patients were higher compared to healthy controls (2.5 ± 0.6 versus 1.9 ± 0.4, p < 0.01) and skin AF was independently associated with age (r = 0.72, p < 0.01). sRAGE levels were higher in T1DM - CD patients compared to healthy controls (1554 ± 449 versus 1309 ± 400, p = 0.049) and independently associated with creatinine levels (r = 0.32, p < 0.01). CONCLUSION: Our study demonstrates that skin AGE and sRAGE levels are elevated in T1DM patients compared with healthy controls. No difference in skin AF or sRAGE levels between T1DM patients with or without CD were observed. The present study suggests that differences in microvascular complications between T1DM and T1DM + CD patients are not due to differences in skin AF or sRAGE levels.

Use of ductoscopy as an additional diagnostic method and its applications in nipple discharge.

AIM: About 1/10 of the patients apply to breast clinics with the complaint of nipple discharge (ND). Surgery is the most frequently preferred treatment method in case of suspicious ND. The contribution of ductoscopy to identify the patients who are candidates for surgery was evaluated and its role to limit the surgery was assessed. METHODS: From November 2005 to December 2010 430 patients with ND were assessed by 456 ductoscopic investigations and the results were analyzed. Complete ductoscopic evaluation was achieved in 84% of cases and 28 patients were offered surgery but did not accept (N.=355). Patients with bloody or serous discharges from a single duct were investigated by ductoscopy under local anesthesia as an office procedure. The patients were grouped according to discharge characteristics and the ductoscopic diagnoses. RESULTS: A total of 223 patients had all three criteria of pathologic ND (PND: single duct, spontaneous and bloody/serous discharge). Twenty-two potential neoplastic or malignant lesion (PNML) and 79 papillomatous lesion (solitary or multiple papilloma) were identified. In 132 patients with just two of the PND criteria, 5 PNML and 18 papillomatous lesions were identified. Twenty-three patients with solitary papilloma that were removed by ductoscopic papillomectomy (DP) are followed up without surgery. CONCLUSION: Ductoscopy helped to identify the patients who required surgical treatment and decreased the number of operations. DP was successfully performed in select group of patients who otherwise would have required surgical resection. Patients with normal ductoscopy findings and patients who were treated with DP successfully can be followed up without the need of surgery.

Compromised quality of life in patients with both Type 1 diabetes mellitus and coeliac disease.

AIMS: Type 1 diabetes mellitus and coeliac disease are two chronic illnesses associated with each other. Both diseases and their treatments can seriously impair quality of life. The objective of the present study was to investigate health-related quality of life in adult patients diagnosed with both Type 1 diabetes and coeliac disease and compare this with healthy control subjects and control subjects who have Type 1 diabetes only. METHODS: A generic measure of health-related quality of life (RAND-36) and a measure of diabetes-specific quality of life (DQOL) questionnaires were sent to patients diagnosed with both Type 1 diabetes and coeliac disease. The control group consisted of patients with Type 1 diabetes without coeliac disease matched for age, gender and socio-economic status. Generic quality of life scores were compared with data from healthy Dutch control subjects. RESULTS: Fifty-seven patients with Type 1 diabetes and coeliac disease were included and no associations between clinical characteristics and quality of life were observed. Women reported a lower quality of life in social functioning, vitality and mental health than men (all P < 0.05). A lower diabetes-specific quality of life was observed regarding diabetes-related worries and social worries in patients with Type 1 diabetes and coeliac disease compared with patients with Type 1 diabetes. Compared with healthy control subjects, quality of life in patients with Type 1 diabetes and coeliac disease was significantly lower, particularly social functioning (Cohen's d = 0.76) and general health perception (Cohen's d = 0.86). CONCLUSIONS: The additional diagnosis of coeliac disease and treatment by gluten-free diet in adult patients with Type 1 diabetes has a considerable, negative impact on quality of life and diabetes-specific quality of life. Women are particularly affected and social functioning and general health perception is compromised.

Angiotensin-converting enzyme gene insertion/deletion polymorphism with metabolic syndrome in Turkish patients.

BACKGROUND: The ACE gene has received substantial attention in recent years as candidate for a variety of diseases. The most common polymorphism in ACE gene is the Insertion/Deletion (I/D, rs4646994) polymorphism located on intron 16. AIM: We investigated the association between metabolic syndrome (MS) and the insertion (I) - deletion (D) polymorphisms in the angiotensin converting enzyme (ACE) gene in south-east of Turkey. SUBJECTS AND METHODS: One hundred and sixty subjects, with 101 cases of MS and 59 age- and gender-matched healthy controls were included in the study. RESULTS: The frequency of ACE I/D polymorphism was found to be 49.5% for DD, 36.6% for ID, and 13.9% for II in the MSstudy group and 44.1% for DD, 42.4% for ID and 13.5% for II in the control group. Allele frequencies were found to be 0.68% for D and 0.32% for I allele in the study group with MS and 0.65% for D, 0.35% for I allele in the control group. The I/D polymorphism of the ACE gene, DD, ID, and II genotypes occurred with similar frequencies in the study group with MS and the control group with no significant differences (p<0.05). On applying one-way analysis of variance to different ACE gene polymorphic groups in patients with MS were not significantly associated to ACE gene polymorphism and waist circumference, systolic blood pressure, diastolic blood pressure, fasting blood glucose, HDL, and LDL (p<0.05). CONCLUSIONS: Further studies of patients in larger numbers and of different ethnic backgrounds may be necessary to elucidate the association between the ACE I/D gene polymorphism and MS.

The insertion/deletion polymorphism in the ACE gene and chronic obstructive pulmonary disease.

An insertion/deletion (I/D) polymorphism was identified in intron 16 of the gene encoding the human angiotensin I-converting enzyme (ACE), a candidate gene for chronic obstructive pulmonary disease (COPD). We investigated the relationship between this polymorphism in the ACE gene and the risk of developing COPD. Sixty-six COPD in-patients and 40 non-smoking control individuals were recruited for this study. The distribution of ACE genotypes in these individuals was studied. The frequencies of ACE genotypes were found to be 47.0% for DD, 30.3% for ID, and 22.7% for II in the COPD group and 32.5% for DD, 47.5% for ID, and 20.0% for II in the control group. The allele frequencies were found to be 0.62% for the D allele and 0.38% for the I allele in the COPD group and 0.56% for the D allele and 0.44% for the I allele in the control group. A significant difference was found between I and D allele frequencies (P < 0.05) of the study and control groups. Our results suggest that this ACE polymorphism may be associated with the development of COPD.

Molecular characterization of the horse isolate of Echinococcus granulosus in Turkey.

Cystic echinococcosis is one of the most important helminthozoonoses, affecting various species of intermediate hosts and humans. In this report, we present Echinococcus granulosus infection in a horse and its molecular characterization. Polymerase chain reaction (PCR) amplification of mitochondrial 12S rRNA (mt-12S rRNA) and partial sequencing of mitochondrial cytochrome c oxidase subunit 1 (mt-CO1) genes were performed. According to the mt-12S rRNA-PCR result, the horse isolate was grouped with E. granulosus sensu stricto (G1-G3) and the partial mt-CO1 sequence corresponded to the G1 strain. This is the first study of the molecular characterization of the horse isolate of E. granulosus in Turkey.

The cause of depression in adolescence: peer bullying.

OBJECTIVE: Depression affects adolescents worldwide and often predicts more serious disease manifestations in later lifetimes. Peer victimization or bullying, another form of child abuse, increases symptoms of depression. In this paper, the relationship between peer bullying and depression in adolescence was investigated. SUBJECTS AND METHODS: Each adolescent who was admitted to the adolescent unit completed forms referred to as the 'Depression Scale For Children' and the 'Multidimensional Peer Victimization Scale'. Sociodemographic features and results of the scales' evaluation were studied. SPSS 16.0 program was used for statistical analysis. The p-value below 0.05 was considered statistically significant. RESULTS: 239 adolescents, 120 of whom were male, were investigated. A positive relationship was determined among total and sub-scale scores of peer victimization-determining scale and depression scale scores. A negative relationship was determined between height, weight, age of the child, and sub-scale score of threat/intimidation. Both the total score of the peer victimization-determining scale and sub-scale scores of ridicule, open attack, and relational attack pertaining to patients with depression proved to be significantly higher than in those without depression. CONCLUSIONS: The awareness of educators and parents, notably adolescents, must be raised in regard to peer victimization, and activities for increasing the communicative skills of adolescents and for allowing them to be able to express their emotions should also be performed. Identifying and preventing peer victimization, one of the causes of depression, and launching the treatment process for this are the first steps to be taken in terms of a healthy adulthood.
