Strong association between VDR FokI (rs2228570) gene variant and serum vitamin D levels in Turkish Cypriots.

Vitamin D is an important molecule to keep teeth, bones and muscles healthy. It is obtained from diet, supplements and primarily from exposure to sunlight. In recent years, vitamin D deficiency is recognised as a worldwide health problem, which results in disturbances in mineral metabolism and skeletal problems. Deficiency might be caused due to sedentary lifestyle, insufficient diet, age as well as some polymorphisms in the VDR gene. In this study the four most common VDR polymorphisms (rs1544410 (BsmI), rs731236 (TaqI), rs7975232 (ApaI) and rs2228570 (FokI)) are investigated in a cohort of Turkish Cypriots and aimed to detect any possible links between low serum vitamin D levels and these variants. The rs2228570 (FokI) variant but not others were shown to have a significant association with decreased serum vitamin D levels in the Turkish Cypriot population.

EMPATHIC-N in a Greek-Cypriot sample: confirming its factorial structure.

BACKGROUND: Family-centered care has been receiving increased attention during the last decades and health professionals recognize family satisfaction with care as an important health indicator. The Empowerment of Parents in The Intensive Care-Neonatology (EMPATHIC-N) is a newly developed, yet empirically reliable and valid measure for the assessment of parental satisfaction with the care provided by Neonatal Intensive Care Units (NICU). The present study aims to present the Greek version of the EMPATHIC-N and to confirm its factorial structure. METHODS: The EMPATHIC-N was translated in Greek using a forward-backward translation and was piloted before use. A sample of 256 families receiving intensive care at the NICU of Archbishop Makarios III Public Hospital in Cyprus which is the only NICU in Cyprus, participated in the validation study of the EMPATHIC-N. Confirmatory factor analyses were performed using SPSS and AMOS 24.0. RESULTS: The Greek version of the EMPATHIC-N had good psychometric characteristics (Cronbach's alpha = .87). The CFAs for the separate subscales of professionalism, organization, information, parental involvement and intervention for the EMPATHIC-N showed that all five subscales represented five distinct components of parental satisfaction with care. The CFA of the general instrument supported that a second-order model with a higher-order factor reflecting the organizational structure (professionalism, intervention and organization loaded on this factor) fitted the data best [χ2 (259) = 405.332, p < .001, ΤLI = .887, CFI = .903, RMSEA = .065 (90% CI .058, .073), SRMR = .0597]. CONCLUSIONS: EMPATHIC-N is a valid and reliable measure for the assessment of parental satisfaction with neonatal care in a Greek-Cypriot context. The organizational dimension of the NICUs is an important component with specific research and clinical implications for the enhancement of parental satisfaction with care.

Impact of Genetic Defects on Coronary Atherosclerosis among Turkish Cypriots.

BACKGROUND: The distribution of gene variants in the Turkish Cypriot population with coronary artery disease has not been investigated. In this study, we sought to research different genetic variants in the susceptibility to coronary artery disease and to identify possible associations between various clinical parameters and the genes involved in blood coagulation as well as glucose and lipid metabolism among the Turkish Cypriots and compared the results with the respective Turkish patients from Turkey. Methods: A total of 187 individuals with coronary artery disease, namely 87 Turkish Cypriot individuals from Northern Cyprus, and 100 Turkish patients from Turkey, were investigated. The presence of CAD was documented with coronary angiography. The genetic susceptibility to coronary artery disease in the cohorts was studied using the variants FV Leiden (G1691A), Factor V R2 mutation (FVR2)(H1299R), PTH (G20210A), FXIII (V34L), ß-Fibrinogen (-455 G>A), PAI-1 (4G/5G), HPA1 (a/b), MTHFR [C677T] and [A1298C], ACE (I/D), Apo B (R3500Q), and Apo E, in addition to the well-known risk factors associated with coronary artery disease. RESULTS: Age, male sex, diabetes mellitus, hyperlipidemia, triglycerides, HDL, and triglyceride/HDL ratio were significantly associated with (P < .05); LDL (P = .05) and total cholesterol (P = .08) was marginally associated with coronary artery disease in the Turkish Cypriot population. The mutations in the MTHFR [C677T] gene variant were marginally higher in the Turkish Cypriot cohort when compared with the Turkish patients from Turkey (P = .06). No significant direct association of any of the gene variants with coronary artery disease in the Turkish Cypriot cohort could be defined. Several of the genetic variants were associated indirectly with the risk factors for coronary artery disease in Turkish Cypriots. MTHFR [A1298C] was found to be marginally associated with low HDL cholesterol (P = .08). MTHFR [C677] wild-type allele was significantly associated with a decreased rate of high LDL cholesterol (P < .05). The HPA-1 a/b variant was significantly associated with an increased rate of high total cholesterol levels (P < .05). Conclusion: Turkish Cypriot patients with coronary artery disease may be more affected by secondary factors, such as diabetes, hypertension, obesity, and sedentary life style when compared with genetic factors, which may be responsible for coronary artery disease.

Predictive factors of disordered eating and body image satisfaction in cyprus.

OBJECTIVE: This study aimed to assess possible relationships and predictor variables between disordered eating attitudes and behaviors, the internalization of the thin ideal construct, body image satisfaction, body image investment, weight-related anxiety, and body mass index (BMI) among Greek-Cypriot female university students in Cyprus. METHOD: A total of 243 female university students responded to self-report measures assessing disordered eating, internalization of the thin ideal, body satisfaction, body image investment, and weight-related anxiety. RESULTS: Disordered eating was positively correlated to the internalization of the thin ideal, body image investment, weight-related anxiety, and BMI and negatively correlated with body image satisfaction. The internalization of the thin ideal was also positively correlated to weight-related anxiety and body image investment and negatively correlated to body image satisfaction. Furthermore, weight-related anxiety and internalization of the thin ideal have been found to be significant predictors of disordered eating attitudes. DISCUSSION: Possible explanations and vulnerability factors are addressed, as well as implication for prevention strategies and future research.

Identification of a mutation in complement factor H-related protein 5 in patients of Cypriot origin with glomerulonephritis.

BACKGROUND: Complement is a key component of the innate immune system, and variation in genes that regulate its activation is associated with renal and other disease. We aimed to establish the genetic basis for a familial disorder of complement regulation associated with persistent microscopic haematuria, recurrent macroscopic haematuria, glomerulonephritis, and progressive renal failure. METHODS: We sought patients from the West London Renal and Transplant Centre (London, UK) with unusual renal disease and affected family members as a method of identification of new genetic causes of kidney disease. Two families of Cypriot origin were identified in which renal disease was consistent with autosomal dominant transmission and renal biopsy of at least one individual showed C3 glomerulonephritis. A mutation was identified via a genome-wide linkage study and candidate gene analysis. A PCR-based diagnostic test was then developed and used to screen for the mutation in population-based samples and in individuals and families with renal disease. FINDINGS: Occurrence of familial renal disease cosegregated with the same mutation in the complement factor H-related protein 5 gene (CFHR5). In a cohort of 84 Cypriots with unexplained renal disease, four had mutation in CFHR5. Overall, we identified 26 individuals with the mutation and evidence of renal disease from 11 ostensibly unrelated kindreds, including the original two families. A mutant CFHR5 protein present in patient serum had reduced affinity for surface-bound complement. We term this renal disease CFHR5 nephropathy. INTERPRETATION: CFHR5 nephropathy accounts for a substantial burden of renal disease in patients of Cypriot origin and can be diagnosed with a specific molecular test. The high risk of progressive renal disease in carriers of the CFHR5 mutation implies that isolated microscopic haematuria or recurrent macroscopic haematuria should not be regarded as a benign finding in individuals of Cypriot descent.

CCR5-Δ32 gene variant frequency in the Turkish Cypriot population.

Recent UNAIDS reports (December 2019) indicate that 37.9 million people have been affected by HIV infection around the globe in 2018, of which 1.7 million are cited as new infections. Human immunodeficiency virus-1 (HIV-1) requires both the CD4 receptor, as the primary receptor, and a chemokine co-receptor to gain entry into the cell. In addition to the WT allele for C-C motif chemokine receptor 5 (CCR5-wt), there is another allele with a 32 bp deletion in the protein coding region (CCR5-Δ32). Individuals who are homozygous for the mutant allele are resistant towards M-tropic HIV infections. In the current study, we aimed to determine the CCR5-Δ32 allele frequency in the Turkish Cypriot population with 326 subjects, 141 men (43.1%) and 185 (56.9%) women. The region of the CCR5 gene containing the Δ32 deletion was amplified using flanking primers. The CCR5 gene Δ32 allele frequency was calculated at 3% and only observed in heterozygous individuals. We hope that our current publication could be a point of dialog between the physicians, the government officials and the public set up a more modern and well-structured HIV screening program in an effort to control and hopefully eliminate HIV from the Turkish Cypriot population.

COL4A3 founder mutations in Greek-Cypriot families with thin basement membrane nephropathy and focal segmental glomerulosclerosis dating from around 18th century.

Mutations in the COL4A3/COL4A4 genes of type IV collagen account for about 40% of cases of thin basement membrane nephropathy, a condition that is estimated to affect 1% or more of the general population. We recently described 10 Cypriot families with familial hematuria and thin basement membrane nephropathy in the presence of focal segmental glomerulosclerosis, with founder mutations on COL4A3 gene. Seven of the families carried mutation G1334E on haplotype K, and another three carried mutation G871C on haplotype Ky. In this report we performed extension of the haplotypes with additional polymorphic markers, 12 for haplotype K and 22 for haplotype Ky, to estimate the linkage disequilibrium value between the mutation and flanking noncommon markers. Haplotype Ky extended to 13.71 Mb, but we did not attempt further analysis owing to the small number of chromosomes. Haplotype K extended to 3.83 Mb, thereby suggesting that it was a much older event compared to mutation G871C. Mutation G1334E was calculated to be about 5-10 generations old with a possible origin between 1693 and 1818 AD, during the Ottoman ruling of the island. Both mutations are clustered in specific geographic regions with apparently formerly isolated populations, although mutation G1334E has been detected elsewhere on the island. The identification of founder mutations in large families with microscopic hematuria greatly facilitates presymptomatic diagnosis and provides useful information on the history of the population, while it may also assist in association studies in search for disease modifier genes.

Perceived freedom-responsibility covariation among Cypriot adolescents.

Participants were 67 Cypriot adolescents who responded to propositions regarding positive, negative, and noncontingent relations between freedom and responsibility. The authors framed items so that half dealt with freedom given responsibility, and the other half dealt with responsibility given freedom. Results indicated participants were more likely to endorse positive-contingency items than they were negative and noncontingency items when items were framed around freedom given responsibility. However, when items were framed around responsibility given freedom, no such differences emerged. The authors discuss results relative to cultural and sociopolitical differences and similarities between children in Cypress and participants in the United States and implications concerning the present study and previous studies regarding these constructs.

Y-chromosomal analysis of Greek Cypriots reveals a primarily common pre-Ottoman paternal ancestry with Turkish Cypriots.

Genetics can provide invaluable information on the ancestry of the current inhabitants of Cyprus. A Y-chromosome analysis was performed to (i) determine paternal ancestry among the Greek Cypriot (GCy) community in the context of the Central and Eastern Mediterranean and the Near East; and (ii) identify genetic similarities and differences between Greek Cypriots (GCy) and Turkish Cypriots (TCy). Our haplotype-based analysis has revealed that GCy and TCy patrilineages derive primarily from a single gene pool and show very close genetic affinity (low genetic differentiation) to Calabrian Italian and Lebanese patrilineages. In terms of more recent (past millennium) ancestry, as indicated by Y-haplotype sharing, GCy and TCy share much more haplotypes between them than with any surrounding population (7-8% of total haplotypes shared), while TCy also share around 3% of haplotypes with mainland Turks, and to a lesser extent with North Africans. In terms of Y-haplogroup frequencies, again GCy and TCy show very similar distributions, with the predominant haplogroups in both being J2a-M410, E-M78, and G2-P287. Overall, GCy also have a similar Y-haplogroup distribution to non-Turkic Anatolian and Southwest Caucasian populations, as well as Cretan Greeks. TCy show a slight shift towards Turkish populations, due to the presence of Eastern Eurasian (some of which of possible Ottoman origin) Y-haplogroups. Overall, the Y-chromosome analysis performed, using both Y-STR haplotype and binary Y-haplogroup data puts Cypriot in the middle of a genetic continuum stretching from the Levant to Southeast Europe and reveals that despite some differences in haplotype sharing and haplogroup structure, Greek Cypriots and Turkish Cypriots share primarily a common pre-Ottoman paternal ancestry.

In-Law Preferences in China and in Cyprus: Differences and Similarities.

Across different times and cultures, parents exercise considerable influence over their children's mate choices. When they do so, parents are looking for specific traits in a prospective daughter- and son-in-law. Using a sample of 674 parents, the current research investigated in-law preferences in China. Participants rated 88 different traits, which were clustered in 10 different preference domains. In-law preferences were found to be contingent on the sex of the in-law and the sex of the parent. The data from the current study were compared with data from a different study which took place in the Republic of Cyprus. It was found that preferences varied in the two samples, but specific cultural differences were identified. It was also found that for both samples, the 10 different domains clustered in two supra-domains. The first supra-domain, where personality traits clustered, was preferred more by both Chinese and Greek-Cypriot parents than the second domain, where the rest of the traits clustered.

Greek Cypriot attitudes toward Turkish Cypriots and Turkish immigrants.

The authors examined the attitudes of 106 Greek Cypriots toward Turkish Cypriots and Turkish immigrants on Cyprus. The authors examined Greek Cypriot attitudes, willingness to cohabit with Turkish Cypriots and Turkish immigrants, and the reasons behind their attitudes in terms of their social-identity perceptions, victimization experiences, and human-rights concerns. A series of repeated measures analyses of variance showed that Greek Cypriots were more willing to cohabit with and had less negative attitudes toward Turkish Cypriots than they were with and toward Turkish immigrants. Women felt more victimized by Turkish Cypriots and Turkish immigrants than did men. Perceived differences in social identity predicted unwillingness to cohabit with Turkish Cypriots. Feelings of victimization predicted negative attitudes toward Turkish Cypriots. Differences in social identity and victimization experiences predicted unwillingness to cohabit with Turkish immigrants. Differences in social identity predicted negative attitudes toward Turkish immigrants. The authors discussed the findings in terms of support for realistic group conflict theories of attitudes and their implications for the coexistence of these ethnic groups in Cyprus and of other ethnic groups in multicultural societies.

Population genetic data for 15 autosomal STR markers in Turkish Cypriots from Cyprus.

Fifteen autosomal short tandem repeat (STR) markers [D8S1179, D21S11, D7S820, CSF1PO, D3S1358, THO1, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA] were analyzed in 501 unrelated, randomly selected Turkish Cypriot individuals from the island of Cyprus. While no locus duplications or null alleles were detected in these samples, eight allelic variants were observed in total, 75% of which were intermediate allelic variants that were absent in the system allelic ladder. Allelic frequencies and statistical parameters of forensic interest were calculated at each locus. For the 15 STR loci tested, combined matching probability (pM) was 2.15717 × 10(-18) and combined power of exclusion (PE) was 0.9999995213. No deviations from the Hardy-Weinberg equilibrium were observed, except for the vWA locus, which became insignificant after the Bonferroni correction for multiple testing. Locus-by-locus comparisons of the Turkish Cypriot allelic frequencies with those published for the neighboring and/or historically related populations with similar loci coverage (Turkish, Greek, Greek Cypriot, Italian and Lebanese) revealed some statistically significant differences at one to five loci. In general, an increase in the number of such significant differences between the Turkish Cypriot data and those for other populations correlated closely with an increase in the geographic distance and/or a decrease in the amount of historical contact. The Turkish Cypriot autosomal STR population study will find immediate use in the Committee on Missing Persons in Cyprus Project on the "Exhumation, Identification and Return of Remains of Missing Persons" and it will also be available for criminal, parentage and other missing person investigations.

Transfusion malaria as a consequence of the 1974 war between Turkey and Greece--two cases.

Two cases of transfusion induced Plasmodium malariae malaria that occurred in August and September 1974 in New York City were direct results of the outbreak of war between Turkey and Greece on the island of Cyprus in July 1974. The cases could be traced to two Greek immigrants with latent infection (one being the longest ever recorded) who independently donated blood after solicitation for people in need living in the country of their ancestors. In view of current rules for donor acceptability, attention should be directed domestically towards careful surveillance for an increased occurrence of transfusion malaria.

Evidence for association of endothelial cell nitric oxide synthase gene polymorphism with earlier progression to end-stage renal disease in a cohort of Hellens from Greece and Cyprus.

Nitric oxide (NO) is thought to be an important factor in the deterioration of renal function. A variable-number tandem 27-bp repeat in intron 4 of the endothelial cell nitric oxide synthase (NOS3) gene has been found to be associated with the plasma levels of NO metabolites. Two alleles are of varied frequencies in different populations (a and b). The shorter allele a has been associated in Japanese populations with the progression of renal disease. Here we investigated this hypothesis by studying the putative role of this polymorphism in a Hellenic population of patients with end-stage renal disease (ESRD). We analyzed the genotypes of 361 ESRD patients and 295 healthy Hellens from Greece and Cyprus. The frequencies of NOS3-4bb, NOS3-4ab, and NOS3-4aa were 0.69, 0.27, and 0.03, respectively, in the control group and 0.71, 0.24, and 0.04 in the group of patients. The data in the two populations were analyzed by the chi-square and Fisher's exact tests. The frequencies of these three genotypes of NOS3-4 polymorphism in the Hellenic population of Greece and Cyprus are similar to those observed in other Caucasian populations. Moreover, our results from three patient groups, autosomal dominant polycystic kidney disease (ADPKD), diabetes mellitus (DM), and non-DM, showed that the frequencies of aa and ab genotypes in the patient populations were not significantly different from those observed in the control group. This work indicates that NOS3-4 polymorphism does not show any association with the development of ESRD in this studied European population. However, examination of the data regarding progression to ESRD within 5 years or after more than 5 years following clinical diagnosis of ADPKD provided evidence of statistical difference (p = 0.048, before Bonferroni correction), with faster progression in the group of ADPKD patients who carried allele a.

Mental health and primary care in ethnic groups Greek Cypriots in London: a preliminary investigation.

The psychiatric symptoms of 50 consecutive Greek Cypriot attenders at a primary health care centre in North London were compared with 50 consecutive native English attenders using the 28 item General Health Questionnaire. No differences were identified between the two ethnic groups. However, the less 'acculturated' Greek Cypriot patients manifested a higher level of psychological disturbance.

In-group favoritism among Native and immigrant Turkish Cypriots: trait evaluations of in-group and out-group targets.

The authors investigated whether in-group favoritism manifests itself as praise for the in-group- or as denigration of the out-group. A total of 450 Turkish Cypriots (248 native, 202 immigrant) judged the applicability of positive and negative trait words to in-group and out-group targets. Both the native and the immigrant groups judged the positive traits as more applicable to their respective in-groups than to the out-group. The native group evaluated the negative social traits as more applicable to the immigrant group. The immigrant group also judged the negative social traits as more applicable to themselves. The two groups did not differ in their judgments for more personal negative traits.

Cross-national stability of a leadership model.

This study explored 60 Greek-Cypriot managers' perceptions of different dimensions of leadership. Analyses using structural equation modeling were performed to examine the invariance of the Flamholtz six-factor leadership model. The same leadership styles observed in samples from countries previously studied were present in the sample from Cyprus. In terms of the importance assigned to each style of leadership, Cypriot managers emphasized the more directive styles to a greater extent than other styles.

Health issues and the Greek Cypriot woman.

This article aims to help health care workers begin to understand the Greek Cypriot woman, her needs, problems and strengths. It will try to explore briefly how Greek Cypriot women perceive health and illness and will discuss factors that influence these perceptions. It will also examine some of the major health problems that Greek Cypriot women face. The article uses material from the author's on-going research into the health needs of the Greek Cypriot community living in North London.

Hyperbaric oxygen for a thalassaemic leg ulcer.

A thalassaemic ulcer in a male Greek Cypriot patient, resistant to standard medical treatment, was treated using hyperbaric oxygen in a recompression chamber. The patient breathed 100% oxygen by face mask whilst the chamber was compressed with air to a pressure of 2.5 atmospheres absolute. The ulcer became fully epithelialised within three weeks of starting treatment.
