Stuttering is associated with psychosocial challenges that may increase vulnerability to social evaluation. This study examined whether adults who stutter (AWS) differ from adults who do not stutter (AWNS) in their need for social approval and investigated the relationship between social approval and resilience-related protective factors in AWS. The final analytic sample comprised 126 adults aged 18–49 years (69 AWS and 57 AWNS). No statistically significant differences were detected in sex or age-category distributions; these tests were used to describe demographic comparability and were not interpreted as evidence of statistical equivalence. Participants completed the Need for Social Approval Scale and the Protective Factors for Psychological Resilience Scale. AWS had a significantly higher total need for social approval than AWNS (76.90 ± 18.93 vs. 67.75 ± 16.10), t(124) = 2.885, p = 0.005, Hedges’ g = 0.513, bootstrap 95% CI [0.17, 0.91]. Within AWS, total need for social approval was moderately and inversely associated with total resilience-related protective factors (Spearman ρ = −0.429, p < 0.001, bootstrap 95% CI [−0.620, −0.192]; Holm-adjusted p = 0.003). In an age- and sex-adjusted sensitivity analysis using all eligible participants aged 18–49 years (69 AWS and 82 AWNS), AWS status remained associated with higher total social approval scores (B = 8.50, 95% CI [1.99, 15.02], p = 0.011). These findings describe associations between approval-oriented social concerns and perceived protective resources; the cross-sectional design does not establish causal mechanisms or intervention targets.

Background: Orofacial dysfunction may co-occur with speech and language disorders. This study compared orofacial function in children with and without speech disorders using the Nordic Orofacial Test-Screening (NOT-S) and examined whether Kotlow tongue-tie severity is associated with orofacial function. Methods: This cross-sectional study included 77 children aged 5–13 years (37 with speech and language disorders [SD]; 40 without [N]). Orofacial function was screened with the NOT-S, and free tongue length was classified according to Kotlow. Nonparametric and exact tests, Poisson regression adjusted for age, sex, and systemic conditions, and sensitivity analyses were used. Results: The SD group had higher NOT-S total (median 3 vs. 1; p < 0.001; r = 0.50) and examination scores (p < 0.001; r = 0.76) than the N group, whereas interview scores did not differ. After Holm correction, facial expression, oral motor function, and speech remained more frequently impaired. The difference persisted after adjustment (incidence rate ratio 2.21, 95% CI 1.53–3.19), in children without systemic conditions, and after exclusion of the speech domain. Tongue-tie prevalence and free tongue length did not differ between groups, and no severity-related association with NOT-S scores emerged. Conclusions: Children with speech disorders had higher NOT-S scores, which persisted after adjustment for age, sex, and systemic conditions, whereas no statistically significant association between tongue-tie severity and orofacial function was demonstrated in this small sample, which does not rule out an effect. Anatomical frenulum assessment alone may be insufficient and should be complemented by functional and speech and language evaluation.

This study aimed to compare cognitive emotion regulation strategies and resilience-related protective factors between people who stutter (PWS) and people who do not stutter (PWNS), and to examine within-group associations between resilience-related protective factor scores and cognitive emotion regulation strategies.Methods The cross-sectional sample comprised 140 adults (PWS, n = 69; PWNS, n = 71), aged 18–65 years. Group assignment was based on participants’ s lf-identification of stuttering status, without independent clinical confirmation. Participants completed the Cognitive Emotion Regulation Questionnaire (CERQ) and the Protective Factors for Resilience Scale (PFRS). Sex distribution was compared using Pearson’s chi-square test, whereas age category and education level were compared using Fisher–Freeman–Halton exact tests because of sparse expected cell counts. Group comparisons were performed using independent-samples t tests or Mann–Whitney U tests according to distributional assumptions, with effect sizes and 95% confidence intervals reported. Within-group associations were examined using Pearson or Spearman correlations, and Benjamini–Hochberg false discovery rate (FDR) correction was applied separately to the 36 subscale-level correlations within each group. Results No statistically significant between-group differences were observed in sex distribution (PWS: 37 men, 32 women; PWNS: 29 men, 42 women; χ²(1) = 2.29, p = .130), age (Fisher–Freeman–Halton exact p = .709), or education (Fisher–Freeman–Halton exact p = .670). No significant between-group differences were found for any of the nine CERQ subscales, and all corresponding effect sizes were small. PWS reported lower Personal, Peer, Family, and Total PFRS scores, with small-to-moderate rank-biserial effects. After Benjamini–Hochberg FDR correction across 36 subscale-level correlations per group, 12 positive associations involving positive refocusing, refocus on planning, and positive reappraisal remained significant in the PWS group, whereas no correlations remained significant in the PWNS group. Conclusions No statistically significant between-group differences were detected across the nine CERQ subscales, while PWS reported lower resilience-related protective resource scores. The observed within-group correlations suggest that adaptive cognitive regulation may be relevant to the psychosocial experience of stuttering; however, the cross-sectional and exploratory nature of the analyses precludes causal or between-group inferences about correlation strength.

Objective SLE is a chronic autoimmune disease. This study aimed to compare pulmonary function, maximal ventilatory capacity assessed by maximal voluntary ventilation (MVV), functional capacity, physical activity level, sleep quality and fatigue between patients with SLE and healthy controls. Methods Respiratory function was assessed using spirometer. Functional capacity was evaluated with the 6-min walk test (6MWT), physical activity with the Global Physical Activity Questionnaire (GPAQ), sleep quality with the Pittsburgh Sleep Quality Index (PSQI) and fatigue with the Fatigue Severity Scale (FSS). Results The cross-sectional study included 25 patients with SLE (21 women, 4 men; mean age 37.00±11.44 years) and 25 healthy controls (20 women, 5 men; mean age 32.24±5.86 years). Groups were similar in age and sex. Compared with healthy controls, patients with SLE had significantly lower forced vital capacity (FVC) (p=0.03), forced expiratory volume in 1 s (FEV1 ) (p=0.01) and MVV (p<0.001). The 6MWT distance and GPAQ total score were also reduced (p<0.01). No differences were observed for FEV₁ /FVC ratio (p=0.75), peak expiratory flow (p=0.32), PSQI (p=0.27) or FSS (p=0.26). In patients with SLE, MVV showed a moderate negative correlation with disease duration (r=−0.585) and a moderate positive correlation with exercise capacity (r=0.618). FEV₁ showed a borderline positive association with exercise capacity (r=0.384). Conclusions Pulmonary function, exercise capacity and physical activity levels were reduced in patients with SLE compared with healthy controls. In addition, pulmonary function parameters were associated with disease duration and exercise capacity, highlighting the importance of early evaluation of respiratory function in patients with SLE.

Günümüzde sağlık turizmi sadece Türkiye'de değil, dünyanın bütün bölgelerinde turizm türleri arasında giderek önem kazanan ve hızla büyüyen bir alan olmuştur. Dünyada iletişim, haberleşme ve ulaşım imkânlarının çoğalmasıyla ve ucuzlamasıyla bireylerin kendi ülkeleri haricinde başka ülkelerde de tedavi olabilmeleri "Sağlık Turizminin" doğmasına neden olmuştur. Bireyler farklı ülkelerdeki tedavi imkanları ve tedavilerin fiyatları konusunda eskiye göre çok daha hızlı ve kolay haberdar olmaktadırlar, ayrıca başarı sağlamış sağlık kuruluşları da bu başarılarını aktaracak medya imkanlarını kullanarak her bireye kolayca ulaşabilmektedirler. Bu haberdarlık bireylerin tedavi konusunda elverişli imkanlar bulduğunda farklı ülkelere seyahat etmeleri ile sonuçlanmakta ve bu tür hareketliliğe "Sağlık Turizmi" denilmektedir. Gelişmiş ve gelişmekte olan ülkeler açısından farklı ve yeni bir pazar ortamı oluşturması sağlık turizmini önemli kılmaktadır. Ülkeler ekonomik getirilerinin fazla olmasından dolayı sağlık turizmi alanına turist çekme yarışı içerisine girmişlerdir. Dünyada giderek artan oranda sağlık harcamaları bu alanı ayrıca değerli kılmakta ve ülkeler arasında sağlık turizmi alanında ciddi rekabet yaşanmaktadır. Türkiye'de sağlık turizmi için uygun imkânlar mevcut olmakla birlikte sağlık turizmi alanında oldukça yüksek potansiyele sahip ülkelerden bir tanesidir. Bu çalışma kapsamında Türkiye'de Sürdürebilir Sağlık Turizmi, Gelişimi ve Pazarlaması konusu verilerle değerlendirilerek incelenmiştir.
