The cytotoxicity of the liquid resin polymer was low at ≤0.2%. For the solid resins, when 100% of the eluate was used from each specimen, the average cell viability was 91.3% for the solid resin polymer and 100% for the hand-mixed self-curing resin, which is higher than the cell viability standard of 70%.

This study aimed to compare the prevalence of periodontal disease in women with PCOS and healthy women.Methods: A total of 196 women aged 17 to 45 years were included in this study. Oral hygiene index-simplified (OHI-S), gingival index (GI), community periodontal index (CPI), and loss of attachment (LA) were assessed. Individuals who smoked, were pregnant, had any systemic disease (such as type 1 or type 2 diabetes mellitus, cardiovascular disease, malignancy, osteoporosis, and thyroid dysfunction), had a history of systemic antibiotic use in the past three months, or received any periodontal intervention in the past 6 months of screening were excluded. Student t-test was used to analyze the data. A p-value of <0.05 was considered statistically significant.Results: Despite similar OHI-S scores (p=0.972) in the two groups, women with PCOS had significantly higher GI, CPI, and LA scores than healthy women (p<0.001).Conclusion: Periodontal disease was more prevalent in women with PCOS than in healthy women. This finding may be due to the synergistic effects of PCOS and periodontitis on proinflammatory cytokines. PCOS may have an effect on periodontal disease, and vice versa. Hence, education on periodontal health and early detection and intervention for periodontal diseases is of paramount importance in patients with PCOS.","PeriodicalId":74020,"journal":{"name":"Journal of Yeungnam medical science","volume":" ","pages":"S17-S22"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10718611/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9785723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lean muscle mass was assessed via bioelectrical impedance analysis and subsequently divided into tertiles. A generalized mixed model with a logit link was employed for repeated measures data analysis, accounting for potential confounders.Results: Analysis encompassed 7,794 participants yielding 49,177 measurements. The findings revealed a markedly increased incidence of NAFLD in the lower tertiles of muscle mass, specifically, tertile 1 (odds ratio [OR], 20.65; 95% confidence interval [CI], 9.66-44.11) and tertile 2 (OR, 4.57; 95% CI, 2.11-9.91), in comparison to tertile 3. Age-dependent decreases in the OR were observed within the tertile 1 group, with ORs of 10.12 at age of 40 years and 4.96 at age of 80 years. Moreover, each 1%-point increment in total muscle mass corresponded with an estimated OR of 0.87 (95% CI, 0.82-0.93) for NAFLD resolution.Conclusions: The study demonstrates a significant association between total muscle mass and NAFLD prevalence among Korean adults. Given the potential endocrine role of muscle mass in NAFLD pathogenesis, interventions aimed at enhancing muscle mass might serve as an effective public health strategy for mitigating NAFLD prevalence.","PeriodicalId":74020,"journal":{"name":"Journal of Yeungnam medical science","volume":" ","pages":"S47-S55"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10718609/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10112217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An active-fixation atrial lead was fixed to the right atrial appendage, and a ventricular lead was fixed to the right ventricle (RV) apex, with acceptable parameters. Two weeks postoperative, the patient visited the clinic for routine examination of the pacemaker parameters. Chest X-ray showed migration of the RV lead beyond the cardiac silhouette.

Computed tomography revealed that the RV lead was positioned beyond the RV and pericardium and into the anterior chest wall. Procedural lead revision was performed with cardiothoracic surgery backup.

However, this method is complex and requires repeated infusions. Therefore, we investigated the surgical outcomes of only antegrade cardioplegia infusion in conventional CABG.Methods: We included 224 patients who underwent isolated CABG between 2017 and 2019. The patients were divided into two groups according to the cardioplegia infusion method: antegrade cardioplegia infusion with del Nido solution (n=111, group I) and antegrade+retrograde cardioplegia infusion with blood cardioplegia solution (n=113, group II).Results: The sinus recovery time after release of the aorta cross-clamp was shorter in group I (3.8±7.1 minutes, n=98) than in group II (5.8±4.1 minutes, n=73) (p=0.033). The total cardioplegia infusion volume was lower in group I (1,998.6±668.6 mL) than in group II (7,321.0±2,865.3 mL) (p<0.001). Creatine kinase-MB levels were significantly lower in group I than in group II (p=0.039).

No significantly enlarged lymph nodes were observed in the inguinal region. She underwent excisional biopsy at our institution. DLBCL was diagnosed based on histological examination. According to the Hans algorithm, the lesion was diagnosed as a non-germinal center B-cell-like subtype. The patient was referred to a hematologic oncologist.

The patient received four cycles of chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone and localized radiation therapy with 36 Gy in 20 fractions.

A total of 4,800 periapical radiographs (1,200 for each implant system) were collected and labeled based on electronic medical records.

Midparental height (MPH), predicted adult height (PAH) obtained using height and bone age (BA) at the time of diagnosis (PAH for BA), and PAH obtained using the Bayley-Pinneau method (PAH by BP) were calculated. Additionally, height at the time of growth completion was compared with the predicted height.Results: The FAHs were 160.71±4.56 cm in the untreated group and 159.31±4.26 cm in the treated group. In the untreated group, the FAH was 0.99±4.50 cm shorter than the MPH but 4.29±3.33 cm and 3.46±3.93 cm greater than the PAH for BA and PAH by BP, respectively.Conclusion: In children diagnosed with CPP between 8 and 9 years of age who were untreated, FAH was greater than PAH for BA and PAH by BP at the time of diagnosis, indicating that the prognosis of FAH was not poor.
