RESUMEN
The purpose of this study was to evaluate the efficacy of concentrated growth factor (CGF) membrane for the sealing of alveolar socket in alveolar ridge preservation (ARP). A total of 22 patients with 24 alveolar sockets were recruited and divided randomly into CGF group and Bio-Gide collagen membrane group. The soft tissue wound healing rate was calculated using intraoral scanner at 3, 7, and 14 days after ARP, and the bone resorption volume at 1, 3, and 5 mm below the alveolar ridge was measured by CBCT at 6 months postoperation. The keratinized gingival width was also measured before and 6 months after ridge preservation. In terms of soft tissue healing rate, the CGF group exhibited significant higher than that of Bio-Gide group at both 7 and 14 days after surgery (P < 0.05). However, there was no significantly different in bone resorption rate and the width of keratinized gingival after 6 months (P > 0.05). Therefore, the use of CGFs membranes for wound closure in ARP is a reliable method, but more clinical data are needed to prove it.

BACKGROUND: The relationship between different risk factors and the cognitive impairment of white matter lesions (WML) remains poorly understood. OBJECTIVES: To investigate the features of cognitive impairment of patients diagnosed with WML accompanied by different risk factors of cerebrovascular diseases. MATERIAL AND METHODS: A total of 157 cases of WML patients were divided into no risk factor group (n = 26), hypertension group (n = 35), diabetes mellitus group (n = 27), dyslipidemia group (n = 30), and mixed factors group (n = 39). RESULTS: The severity of WML (Fazekas score) in the hypertension and mixed factors groups was higher than in the non-risk factors group. The Montreal Cognitive Assessment (MoCA) scores in the hypertension and mixed factors groups were lower than in the non-risk factors group. The scores of MoCA, immediate memory and delayed recall in the hypertension and mixed factors groups with Fazekas score ≥3 were lower than in the peer group with Fazekas score <3. The scores of MoCA and immediate memory in the hypertension and mixed factors groups with Fazekas score ≥3 were lower than in the non-risk factors group with Fazekas score ≥3. CONCLUSIONS: Hypertension aggravates the severity of WML and cognitive impairment. The severity of WML is positively correlated with the severity of cognitive impairment accompanied by these risk factors.

OBJECTIVE: To investigate the anxiety disorders and influence factors that occur in adolescent patients with cleft lip and palate and to provide theoretical foundation for mental intervention. METHODS: A total of 120 adolescent patients with cleft lip and palate were investigated using a general information questionnaire, the self-rating anxiety scale, and the social support rating scale (SSRS). The influence factors of anxiety disorders were analyzed. RESULTS: The effective questionnaires were 119. The occurrence rate of anxiety disorder in adolescent patients was 49.6% (59/119), and the occurrence rates of mild, moderate, and severe anxieties were 41.2% (49/119), 7.6% (9/119), and 0.8% (1/119), respectively. The gender, residential area, disease category, family status (one child or no children), and incidence rate of anxiety disorder in patients were statistically different (P<0.05). The SSRS scores of patients with anxiety disorder were lower than those of patients without anxiety disorder (P<0.05). Multiple regression analysis showed that gender and social support were predictive factors of the occurrence of anxiety disorder (R=0.318). CONCLUSION: A high anxiety disorder rate occurred in adolescent patients with cleft lip and palate. dender and social support were important influencing factors for anxiety disorder. In the after-mental intervention, considerable attention should be given to the anxiety disorders of patients and improve their mental health.
