ABSTRACT

Personal identity and social identification processes can be challenging for adolescents belonging to an ethnic minority, who have to cope with the acculturation task of navigating several (and often conflictual) alternatives put forth by their cultural heritage community and destination society. Because identity and acculturation tasks are embedded in core domains of adolescents' life, this three-wave longitudinal study with ethnic minority adolescents (N = 244, 43.4% male; Mage = 14.9) examined how personal identity processes and social identifications are related to acculturation orientations in the education and friendship domains. Results of traditional cross-lagged models showed that, in the educational domain, adolescents who scored higher on cultural heritage maintenance compared to their peers, scored higher on commitment later on. In the friendship domain, stronger associations were found, such that adolescents who scored higher on cultural heritage maintenance compared to their peers, reported higher commitment and in-depth exploration later on, while those who scored higher on identification with friends reported over time also higher cultural heritage maintenance and destination culture adoption. Random-intercept crossed-lagged models indicated that, when adolescents reported above their own average on reconsideration of educational commitment, they reported increased cultural heritage maintenance later on. Furthermore, consistent associations (at baseline and over time) emerged. Overall, this study points to virtuous alliances between the fulfillment of tasks related to adolescents' identity development and acculturation.

ABSTRACT

This study investigated the associations between cultural diversity approaches endorsed by teachers and adolescents' positive and negative intergroup contact in schools. Participants were 984 adolescents (Mage  = 14.66; 62.7% female; 24.8% ethnic minority) involved in a three-wave longitudinal study between 2019 and 2020. Results highlighted that perceived equal treatment by teachers was related to higher positive and lower negative contact over time. However, perceived support for contact and cooperation and interest of teachers in children's cultural background were not related to either positive or negative contact over time. Importantly, the results were replicated across ethnic minority and majority adolescents. This study provides novel insights into the key role that teachers can play in promoting cultural diversity approaches to facilitate harmonious intergroup interactions in schools.

ABSTRACT

This study aims to tackle positive and negative intergroup contact in school and out-of-school contexts to test whether a spillover effect (i.e., the extent to which experiences that individuals have in one context spill over into another) applies to intergroup contact. Participants were 984 adolescents (Mage = 14.66; 62.7% female; 24.8% ethnic minority). Results indicated that positive contact in school was related over time to higher positive contact in out-of-school contexts and vice versa (i.e., valence consistent spillover effect). Positive contact in school was linked over time to lower negative contact in out-of-school contexts (i.e., valence inconsistent spillover effect). Overall, this study provides novel insights into the transmission of adolescents' intergroup contact across socialization contexts by emphasizing the leading role of positive contact in schools.

ABSTRACT

Objective. Prolactinoma, as a common endocrine disorder and the most frequent type of pituitary tumor, acts primarily as a suppressor on the gonadal functions. It is generally successfully treated with dopamine agonists; however, treatment resistance still remains in an unneglectable ratio. In this study, we aimed to identify factors, which may play a role in the treatment response. Methods. Seventy-six patients with prolactinoma, who have been routinely followed between 2018 and 2022 in Istanbul Research and Educational Hospital Endocrinology Outpatient Clinic, were included into the study. Initial prolactin level, adenoma size, baseline weight, body mass index (BMI), glucose, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride levels were obtained from the patient's medical records. The patients were divided into two groups: treatment respondent and non-respondent (refractory) ones, according to treatment response in the duration as suggested by the guidelines. The treatment respondent and non-respondent groups were compared according to the initial and the 3rd month prolactin levels, adenoma size, weight, BMI, and metabolic values. Results. The initial tumor diameter was 15.27±10.62 mm in the refractory and 7.42±4.42 mm in the treatment respondent groups (p=0.01). The refractory group had higher prolactin baseline level 269.96±275.78 µg/l vs. 124.55±67.35 µg/l of the respondent group (p=0.01). The refractory group had higher the 3rd month prolactin level 50.97±52.55 µg/l vs. 29.70±27.31 µg/l of the respondent group (p=0.04). The refractory group had higher frequency of cystic/hemorrhagic adenoma (47.6%, n=11/21) (p=0.01), baseline pituitary failure (33.3%, n=7/21) (p=0.01), and baseline cavernous sinus invasion (25.8, n=5/21) (p=0.01). The treatment respondent group had lower initial body weight (69.54±17.51 kg vs. 83.29±16.21 kg) (p<0.01), and lower BMI (25.98±5.47 kg/m2 vs. 27.69±6.42 kg/m2) (p=0.02). Conclusions. In this study, initial tumor size, male gender, weight, BMI, the 3rd month prolactin level, initial pituitary deficiency, and cystic/hemorrhagic component in pituitary imaging in patients with prolactinoma were associated with a lower treatment response.

ABSTRACT

Friendships have important implications for adolescents' psychological and social adjustment. However, there is still limited evidence on how different same-ethnic and cross-ethnic friendships are formed and regarding their role in refugee adjustment. Therefore, the present study was designed to examine the interplay of parents' and adolescents' same-ethnic and cross-ethnic friendships with adolescents' own psychological and social adjustment among refugee adolescents. Participants were 208 Syrian refugees (71.2% female; Mage = 15.35, SDage = 0.95) in the Southeastern Anatolia Region of Turkey. Findings indicated that refugee parents' same-ethnic and cross-ethnic friendships were positively related to their children's same-ethnic and cross-ethnic friendships. Moreover, parents' same-ethnic friendships were negatively linked with adolescents' social well-being, whereas parents' cross-ethnic friendships were positively related to adolescents' social well-being. Furthermore, adolescents' same-ethnic and cross-ethnic friendships were both positively related to adolescents' social well-being, and cross-ethnic friendships were also positively associated with psychological well-being. These findings suggest that adolescents' cross-ethnic friendships mediated the positive associations of parents' cross-ethnic friendships with adolescents' social and psychological well-being. Overall, our study provides novel insights into the protective roles of diverse friendships for refugee adolescents.

ABSTRACT

Recent developments in the acculturation literature have emphasized the importance of adopting intergroup perspectives that provide a valuable background for investigating how acculturation orientations (i.e., maintenance of the culture of origin and the adoption of the destination culture) of adolescents from migrant families are embedded in their proximal socialization contexts. Accordingly, we sought to understand the combined effects of the perceived parents' acculturation orientations and classmates' acculturation preferences on adolescents' own acculturation orientations in two independent cultural contexts, namely North-East of Italy (Study I) and South-East of Turkey (Study II). Participants were 269 (53.2% female; Mage = 14.77) and 211 (71.1% female; Mage = 15.37) adolescents from migrant families in Italy and in Turkey, respectively. Findings indicated that adolescents' acculturation orientations were influenced by their perceptions of both parents' acculturation orientations and classmates' acculturation preferences. In addition, the effects of parents' adoption of the destination culture were stronger than the effects of classmates' preferences for adoption of the destination culture in both countries. However, the effects of parents' maintenance of the culture of origin were stronger than the effects of classmates' preferences for maintaining the culture of origin in Turkey, but not in Italy.

ABSTRACT

Primary hyperparathyroidism is well known to be associated with cardiovascular morbidity and mortality. However, it is unclear whether normocalcemic primary hyperparathyroidism (NC-PHPT) and hypercalcemic primary hyperparathyroidism (HC-PHPT) share the same risk factors. We aimed to determine prevalence of metabolic syndrome in NC-PHPT and compare metabolic syndrome parameters and insulin resistance in NC-PHPT subjects with those in HC-PHPT and control subjects. After excluding patients with secondary hyperparathyroidism, the study enrolled 25 patients with NC-PHPT, 24 patients with HC-PHPT and 30 age-gender matched controls. All participants were evaluated using the International Diabetes Federation (IDF)-2006 metabolic syndrome criteria. Compared with HC-PHPT patients, NC-PHPT patients had similar prevalence of metabolic syndrome, glucose intolerance, and previous history of hypertension/anti-hypertensive medications, but compared with controls, NC-PHPT patients had significantly higher prevalence of glucose intolerance and previous history of hypertension/anti-hypertensive medications. Not serum calcium but PTH concentration was found to be significantly higher in those with glucose intolerance. Serum fasting triglyceride concentration and waist circumference were found to be positively correlated only with serum PTH concentration. In conclusion, patients with NC-PHPT may be prone to similar metabolic disturbances linked to higher cardiovascular risk like patients with HC-PHPT. Although NC-PHPT is thought to occur early in the development of the classical disease, it should be monitored regularly because of its metabolic consequences.

ABSTRACT

Objective: We aimed to identify metabolic dysfunction in non-functioning adrenal adenomas (NFAAs) and Visceral Adiposity Index (VAI) predictability in the practical estimation of metabolic syndrome (MetS) in NFAAs. Subjects and methods: 134 NFAA patients and 68 control subjects matched for age, sex, and body mass index (BMI) were included in the study. After physical, biochemical, and endocrine evaluation, IDF and NCEP ATP III criteria were used to determine MetS. HOMA-IR and VAI were calculated for both study group subjects. Results: MetS was significantly higher in the NFAA patients. The incidence of MetS by IDF and NCEP criteria was 52.9%,48.5% in the NFAI and 32.3%,30.8% in the control group (p < 0.01, p = 0.02). The risk of MetS was increased in NFAA (75.6 vs. 24.4%, p = 0.017, OR = 1.34, 95% CI = 1.06-1.68). Glucose, HOMA IR, hypertension, and VAI were significantly increased in NFAA patients. The risk of MetS was independently associated with high VAI (79.2 vs. 20.8%, p = 0.001, OR = 2.22; 95% CI = 1.70-2.91). Conclusion: MetS, insulin resistance, and VAI are more prevalant in NFAA patients than in healthy individuals. VAI can be used with high specificity to estimate MetS in NFAA patients.

ABSTRACT

In the present contribution, we aimed to test the psychometric properties of the Intergroup Contact Interactions Scale (ICIS). The ICIS is a tool that can easily be administered to assess ethnic minority and majority adolescents' positive and negative intergroup contact in both school and out-of-school contexts. Study I included 169 adolescents in Italy (40.2% ethnic minority adolescents; 51.5% female; M age = 14.41) and provided initial support for the two-factor structure (i.e., positive and negative contact) of the ICIS in both school and out-of-school contexts. Study II, conducted with a sample of 1,037 adolescents in Italy (26.5% ethnic minority adolescents; 59.7% female; M age = 14.58), indicated that the fit of the two-factor ICIS structure was excellent for both school and out-of-school contexts. Measurement invariance across ethnic minority and majority adolescents was also established. Convergent validity was also ascertained by highlighting meaningful associations of adolescents' positive and negative contact with the quantity of contact as well as with their perceptions regarding parents' positive and negative contact with outgroup members. Study III, involving a sample of 641 adolescents in Turkey (32.9% ethnic minority adolescents; 69.6% female; M age = 15.51), supported the two-factor structure, as well as convergent validity, of the ICIS in both contexts. Measurement invariance across ethnic groups was also established. Overall, these studies suggest that the ICIS is a reliable measure for studying positive and negative intergroup contact among ethnic minority and majority adolescents across school and out-of-school contexts.

ABSTRACT

Background: Obesity and metabolic syndrome (MetS) are growing problems in type 1 diabetic patients; these can influence clinical complications and also treatment regimens. Visceral adipose tissue inflammation plays an important role in cardiovascular complications. Visceral adiposity index (VAI), lipid accumulation product index (LAP), and triglyceride (TG)/high-density lipoprotein (HDL) ratio have been strongly correlated with insulin resistance and visceral adipose tissue amount in previous studies. Therefore, this study aimed to investigate and compare the usefulness of these indices to detect MetS in patients with type 1 diabetes mellitus (T1DM). Materials and Methods: Patients with T1DM and gender- and age-matched controls were included in this cross-sectional study. MetS was defined using both International Diabetes Federation (IDF), World Health Organization (WHO), and National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. T1DM patients were divided into two groups according to the IDF criteria. VAI, LAP, and TG/HDL ratio were calculated for all patients. Groups were compared accordingly. Results: One hundred twenty-six patients with T1DM were included in the study. Increased VAI was observed in association with MetS. Patients with MetS (32.2%) had the highest VAI than healthy controls (8.21 ± 8.86; 3.49 ± 2.73, respectively, P < 0.01). For determining MetS in type 1 diabetes, the cutoff value of VAI was 2.65 [area under the curve (AUC) = 0.837, sensitivity 80.0%, specificity 72.8%], LAP was 27.57 (AUC = 0.842, sensitivity 80.0%, specificity74.0%), TG/HDL ratio was 2.18 (AUC = 0.826, sensitivity 75.0%, specificity 74.0%), each P < 0.001. Conclusions: MetS becomes increasingly common in T1DM. VAI, LAP, and TG/HDL ratio were useful for predicting MetS in patients with T1DM.

ABSTRACT

AIMS: The impact of prolonged COVID-19 lockdown on metabolic control in type 2 diabetes patients and healthy individuals has not exactly been known. We aimed to evaluate the change in body weight and metabolic control in type 2 diabetic and non-diabetic healthy subjects during the prolonged lockdown period. METHODS: Diabetic (n = 85), and age-and sex-matched non-diabetic subjects (n = 55) were included in this prospective study. Body mass index and metabolic parameters were compared between before and 6th months of lockdown. Changes in values were evaluated using the difference before and after lockdown. RESULTS: Age (54.81 ± 10.53 vs. 52.61 ± 4.88 years), gender (female, 68.2% vs. 56.4%) and, BMI (33.44 ± 6.48 vs. 31.63 ± 3.57 kg/m2) were similar between groups (p > 0.05). Before and after lockdown, BMI increased both in non-diabetic (0.54 ± 0.95 kg) and diabetic groups (1.91 ± 5.48 kg) (p > 0.05). Increase in HbA1c was more in diabetic than in non-diabetic groups (0.71 ± 1.35 vs. 0.02 ± 0.19%, p = 0.002). Glucose, LDL-C, and TG increased in diabetic (39.69 ± 74.69, 7.60 ± 34.33, and 58.21 ± 133.54 mg/dl, p < 0.05) whereas non significantly decreased in non-diabetic group (-0.51 ± 4.40, -3.52 ± 14.53, and -6.47 ± 41.77 mg/dl, respectively. After adjusting BMI, increase in blood glucose (p = 0.021), HbA1c (p = 0.018), and TG (p = 0.041) levels were more in diabetic than non-diabetic group. Duration of diabetes was an independent predictor of the change in HbA1c (OR: 1.2, 95% CI = 1.1-1.8, p = 0.032). CONCLUSIONS: Body weight gain was observed in type 2 diabetic patients and healthy subjects. This is the first study to show that prolonged lockdown COVID-19 pandemic worsened glucose regulation and increased TG level in diabetes mellitus independent of weight gain.

ABSTRACT

Hypoxia is linked to an inflammatory imbalance in obstructive sleep apnea syndrome (OSAS). Circulating soluble tumor necrosis factor (TNF)-like weak inducer of apoptosis (sTWEAK) is a cytokine that regulates inflammation and insulin resistance in adipose tissue. This study first investigated sTWEAK concentrations in patients OSAS and evaluated associations between sTWEAK concentrations and visceral adiposity, metabolic dysfunction, and hypoxia observed in OSAS. Forty age, sex, and body mass index-matched patients with simple habitual snoring (HSS) and 70 patients with OSAS were included. Patients were divided according to OSAS severity: mild-moderate (apnea-hypopnea index, AHI 5-30 events/h) and severe (AHI ≥ 30 events/h). Anthropometric data, glucose metabolism, visceral fat (VF) ratio, and sTWEAK levels were compared. sTWEAK levels were higher in the OSAS group than in the HSS group (931.23 ± 136.48 vs. 735.22 ± 102.84 ng/L, p = 0.001). sTWEAK levels were higher in severe OSAS than in mild-moderate OSAS (1031.83 ± 146.69 vs. 891.01 ± 110.01 ng/L, p = 0.002. When we evaluated the sTWEAK value and AHI, VF ratio, total cholesterol, blood pressure, homeostasis model of assessment-insulin resistance, and high-sensitivity C-reactive protein using multiple regression analysis, a significant correlation was found between sTWEAK levels and AHI (p < 0.001). It was found that sTWEAK levels were not correlated with glucose metabolism and VF ratio. Increased circulating sTWEAK levels were associated with the severity of OSAS. High sTWEAK levels were correlated with increased AHI. sTWEAK concentrations are linked to severe OSAS.

ABSTRACT

The aim of the present study is to test the factor structure and reliability of the Experience of Close Relationships-Relationship Structures Scale (ECR-RS) mother, father, romantic partner, close friend forms among Turkish adolescents. In order to test the structure validity of the ECR-RS, exploratory factor analysis is performed on a sample of 214 participants in Study 1, and to further investigate the structure validity, confirmatory factor analysis is performed on a second sample of 286 participants in Study 2. Within the scope of the reliability studies of the ECR-RS, internal reliability and test-retest reliability of the Turkish ECR-RS are also tested. The results of the explanatory and confirmatory factor analysis, Cronbach's alpha coefficients, and test-retest reliability scores supported the original two-factor structure (attachment avoidance and attachment anxiety) for all forms of the ECR-RS among Turkish adolescents.
