OBJECTIVES: This study aimed to investigate the correlation between clinical symptoms and unilateral chewing habits in patients with temporomandibular disorder (TMD) accompanied by tinnitus. METHODS: A total of 285 patients diagnosed with TMD at the Department of Stomatology of the First Medical Center of Chinese People's Liberation Army General Hospital between December 2020 and May 2024 were included and divided into two groups: tinnitus group and non-tinnitus group. Analysis was conducted on the proportion of patients with unilateral chewing habits in both groups, the correlation between the side of tinnitus and the side of unilateral chewing, and the correlation of tinnitus with TMD clinical symptoms (joint clicking, joint pain, and limited mouth opening) and unilateral chewing habits. The correlation of the type of disc displacement with unilateral chewing and tinnitus was also examined. RESULTS: In the tinnitus group, the proportions of patients with and without unilateral chewing habits were 90.70% (39/43) and 9.30% (4/43), respectively. In the non-tinnitus group, the proportions of patients with and without unilateral chewing habits were 76.03% (184/242) and 23.97% (58/242), respectively. The proportion of patients with unilateral chewing habits in the tinnitus group was significantly higher than in the non-tinnitus group (χ²=4.613, P<0.05). Correlation analysis showed a positive correlation between tinnitus and unilateral chewing habits (P<0.05). In the left-sided tinnitus group, the proportion of left-sided unilateral chewers [54.55% (12/22)] was higher than that of right-sided unilateral chewers [45.45% (10/22)]. In the right-sided tinnitus group, the proportion of right-sided unilateral chewers [81.82% (9/11)] was higher than that of left-sided unilateral chewers [18.18% (2/11)]. The difference was statistically significant (χ²=7.282, P<0.05). A positive correlation was also found between the side of tinnitus and the side of unilateral chewing habits (P<0.05). The proportion of patients with pain was significantly higher in the tinnitus group than in the non-tinnitus group (P<0.05). No significant difference in the proportion of joint clicking or limited mouth opening and disc displacement (no disc displacement, unilateral disc displacement, bilateral disc displacement, reducible disc displacement, or irreducible disc displacement) was found between the tinnitus and non-tinnitus groups (P>0.05). CONCLUSIONS TMD with unilateral chewing habits may be a contributing factor to unexplained tinnitus. Unexplained tinnitus is correlated with joint pain in patients with TMD.

Kidney stone is a highly recurrent disease in the urinary tract system. Most kidney stones are calcium stones, usually consisting of either calcium oxalate or calcium phosphate. Supersaturation of soluble calcium, oxalate, phosphate, and citrate in the urine is the basis for calcium stone formation. Genetics, diet, low physical activity, and individual habits contribute to the formation of kidney stones. In this review, the associations of the risk of kidney stones with oxalate consumption and some individual habits, such as smoking, alcohol drinking, and opium consumption, are summarized.

Children in the mixed dentition grow rapidly, and various types of malocclusion often appear in this period. At the same time, there are many environmental factors affecting the development of the occlusion at this stage. Functional abnormalities related to lip, tongue, articulation and breathing, and impacted teeth should be actively intervened and blocked to avoid the continued development of the deformity. Appropriate orthopedic devices should be used in patients with skeletal malocclusion, if necessary, for growth modification and the influence of congenital factors and the prognosis of treatment should be fully evaluated. Over-intervention of the temporary malocclusions in the mixed dentition should be avoided. In conclusion, early orthodontic treatment in the mixed dentition requires a comprehensive assessment of the treatment need, risks, timing, cost and the ultimate benefit of the patient. The timing of orthodontic treatment is not the sooner the better. The indications must be strictly controlled, and the necessity and limitations must be carefully considered.

Oral habits, such as mouth breathing, sucking, and lip and tongue habits, are important factors that lead to malocclusion. The abnormal pressure will disrupt the muscle balance of the oral and maxillofacial complex and interfere with the normal development of the maxillofacial complex. Therefore, early diagnosis and successful treatment of oral habits are pivotal to the early treatment of malocclusion. This paper discusses the malocclusion caused by children's oral habits and the corresponding intervention methods.

OBJECTIVE: To investigate the correlation between drinking habits and pathological characteristics of patients with upper tract urothelial carcinoma (UTUC). METHODS: A preoperative questionnaire survey was conducted to understand the drinking habits of UTUC patients who were admitted to the Department of Urology, Peking University First Hospital for radical nephroureterectomy within one year from August 2020 to July 2021, and statistical analysis was performed in combination with their postoperative pathological characteristics. The statistical procedure was performed using SPSS 22.0 software, and firstly, the preliminary analysis was performed one by one using the columnar χ² test on the pathological characteristics of UTUC tumors as the dependent variable and the factors related to patients' general information, past history and drinking habits as the independent variables, and the independent variables that met P < 0.2 between the case and control groups for each dependent variable were specified for screening. The screened variables were included in the binary Logistic regression analysis. A difference of P < 0.05 was used to indicate a statistically significant difference. RESULTS: A total of 239 patients, 134 males and 105 females, with a mean age of (68.1±9.98)years and a median disease duration of 4.8 months, were included in this study. Multifactorial Logistic regression results suggested that after adjusting for the effects of other variables, UTUC patients who had the habit of drinking at least once every hour during the daytime had a significantly increased risk of high grade (G3) tumors(OR=1.941, 95%CI: 0.352-1.029, P < 0.01); these patients also had a significantly decreased risk of multifocal UTUC tumors (OR=0.344, 95% CI: 1.18-5.582, P=0.004). The patients who had the habit of drinking over 100 mL water each time had a significantly decreased risk of mutifocal UTUC incidence (OR=0.477, 95%CI: 0.225-1.012, P=0.046). Patients who pay attention to daily water intakes had a significantly increased risk of renipelvic carcinoma (OR=2.530, 95%CI: 1.434-4.463, P=0.001) and a significantly decreased risk of ureteral carcinoma (OR=0.314, 95%CI: 0.172-0.573, P < 0.01). Other variables included in the regression model did not differ significantly in their effects on the occurrence of tumor pathological characteristics. CONCLUSION Having the awareness of drinking water every 1 h during the day, drinking over 100 mL water each time, having the awareness of daily drinking habits correlated significantly with pathological characteristics of UTUC such as the presence of G3 tumor, multifocal tumors and location of the tumor. This conclusion still needs to be verified by subsequent trials with higher levels of evidence.

BACKGROUND: Many studies have already reported on the relationship between exercise habits and health among schoolchildren. However, few have examined social and/or family factors as determinants of exercise habits. METHODS: This study's participants included 1721 schoolchildren aged between 6 and 13 who were involved in the Super Shokuiku School Project in January 2016. A survey was conducted to assess gender, grade level, physical activity, lifestyle, overall health, enrichment of school life, social background, and parental lifestyles. Both dislike and lack of physical activity were used to measure poor exercise habits; correlates were analyzed using logistic regression. RESULTS: "Lack of close friends" had the strongest links with both dislike (adjusted odds ratio [OR] 5.30; 95% confidence interval [CI], 2.78-10.1) and lack of (adjusted OR 5.40; 95% CI, 2.81-10.4) physical activity. Further, children who engaged in long periods of screen time and lacked parental communication also tended to dislike and lack physical activity. Children with mothers who were unemployed (housewives) and had unhealthy lifestyles, as well as those with poor health, were also more likely to lack physical activity. CONCLUSION Social and family factors (e.g., having close friends) may be determinants of exercise habits among schoolchildren, independent of their own lifestyle factors. Although a longitudinal study is needed to determine causality, substantial attention may thus be required to these factors when promoting physical activity in children.

Isolating the effects of a single nutrient or food in relation to health outcomes including increased skeletal muscle mass is a challenging task because dietary constituents are highly correlated and synergistic. Hence, diet pattern analysis may be used to investigate the role of certain diets in health outcomes. The present study investigated the dietary patterns and their relationship to skeletal muscle mass in Korean adults. Data were extracted from the 2008–2011 Korea National Health and Nutrition Examination Surveys. To explore the dietary patterns of the study subjects, factor analysis was performed using data obtained from a 24-hour recall. The skeletal muscle index according to dietary pattern scores was then investigated to estimate the changes in skeletal muscle mass. Three patterns were initially identified from the factor analysis. Of these vegetables and fish (VF) pattern was the primary factor with high reliability and was a common factor in sex-separated analyses. The VF pattern scores were positively associated with increased skeletal muscle mass in both men and women. Further analysis according to quartile levels of VF pattern scores showed a positive association between skeletal muscle mass and VF pattern in men but not in women. These results suggest that dietary patterns focused on vegetables and seafoods may contribute to increased skeletal muscle mass in Korean men but that sex difference should be considered in nutrition care for skeletal muscle health.

Maternal nutritional status during pregnancy will affect the outcomes for the mother and the newborn. Maternal diet was assessed in 150 pregnant women during the first trimester of pregnancy by a 168-item food frequency questionnaire. Dietary patterns were explored by Factor analysis, and association of patterns with maternal and neonatal outcomes such as gestational diabetes mellitus (GDM), anemia and anthropometric indices were determined by analysis of variance and linear regression analysis. Three major dietary patterns were identified: 1) High Carbohydrate-Lower Fat (mean age, 27.67 ± 6.1; n = 34), 2) High Carbohydrate-Higher Fat (27.70 ± 4.1; n = 55), and 3) High Fiber (29.27 ± 5.8; n = 61). A significant difference was observed between maternal dietary patterns (p < 0.01) for GDM, while it was not significant for anemia. Also, the number of preterm and low birth weight (LBM) infants as well as mean weight, height and head circumference of the infants did not differ significantly between patterns, but there was a significant difference between the maternal dietary patterns about the number of macrosomic babies, which was higher in the second (n = 9) and third (n = 9) dietary patterns (p < 0.01). After adjusting for mothers' age, disease history, disease status, and energy intake, High Carbohydrate-Lower Fat dietary pattern was more associated with GDM than crude model (p = 0.01 vs. p = 0.02). The present study indicated a significant relationship between maternal dietary patterns before pregnancy and GDM and fetal macrosomia.

This study aimed to assess the dietary quality and food habits in children with pervasive developmental disorder (PDD) and to evaluate the relationship between diet quality of children with PDDs and their caregivers' feeding practice and nutritional perceptions. Twenty-one pairs of caregivers and their children with PDD were surveyed. The caregivers completed surveys regarding their children's weight status, food habits, and dietary quality and their food habits, nutritional perceptions, knowledge, and feeding practices. Dietary quality was assessed as mean adequacy ratio, dietary diversity score (DDS), dietary variety score (DVS), and Index of Nutritional Quality (INQ). The children were in the normal ranges of body mass index (BMI) and Röhrer index. Having three times a meal, regular meal time, salty taste of the caregiver were related to those of the children with PDD (β = 0.533, 0.447, and 0.886, respectively; p < 0.05). Child control, food as reward, involvement, pressure, and restriction for the health of the caregiver were positively related to DDS, DVS, and INQ of the children with PDD (p < 0.05). High feeding stress and nutritional knowledge of the caregiver were related to the high BMI of the children with PDD (β = 0.445 and 0.602, respectively; p < 0.05), whereas emotion regulation, encourage balance and variety, and involvement of caregiver were negatively related to BMI (β = −0.426, −0.430, and −0.388, respectively; p < 0.05). In conclusion, food habits of children with PDD were closely related to those of caregiver. To improve nutritional status, more insightful understand will be required by considering their developmental differences in this population.
