Background: Posterior spinal fusion is performed for severe adolescent idiopathic scoliosis (AIS), with bone graft playing a critical role in achieving solid fusion. Iliac crest bone graft (ICBG) is the gold standard but has donor site morbidity, leading to increased use of non-ICBG. This study compared the effectiveness and safety of ICBG and non-ICBG bone grafts in AIS. Methods: This meta-analysis included 23 studies with 3,350 patients, categorized into ICBG and non-ICBG groups. The primary outcome was fusion rate; secondary outcomes were implant-related complication rate, infection rate, donor site pain, blood loss, and operation time. A proportion meta-analysis was conducted to estimate binary outcomes, and a weighted mean model was used to estimate continuous variables. Results: The fusion rate was 97% (95% confidence interval [CI], 93-99) in ICBG group and 97% (95% CI, 95-98) in non-ICBG group. Implant-related complications occurred in 5% (95% CI, 3-7) and 4% (95% CI, 2-6) of each group, while surgical site infections occurred in 3% (95% CI, 2-7) and 2% (95% CI, 1-3). Donor site pain was observed exclusively in ICBG group, with a prevalence of 49% (95% CI, 3–97). Estimated pooled blood loss was 1,461.10 mL (95% CI, 545.30-2,376.90) in ICBG group and 1,047.45 mL (95% CI, 666.92-1,427.99) in non-ICBG group. The estimated pooled operation time was 246.77 (95% CI, 221.74-271.80) and 232.37 (95% CI, 194.88-269.86) for each group. Conclusions Considering both ICBG and non-ICBG demonstrated high fusion rates and low complication rates, non-ICBG grafts may serve as an effective and safe alternative to ICBG, minimizing morbidity, donor site pain, and blood loss.

OBJECTIVES: This study was conducted to identify the demand and willingness to pay for oral hygiene services among elderly people with long-term care insurance. METHODS: Our study was a cross-sectional analysis. Subjects comprised 126 elderly individuals from long-term home-care centers. A total of 28 centers were selected through convenience sampling from among 78 centers in ○○. For analysis, semi-structured questionnaires that required about 20–30 minutes to complete were used. Analysis was performed using SPSS 23.0 software. RESULTS: The overall demand for oral hygiene services was 44.4%, and willingness to pay was 31.0%. Thirty-three people (58.9%) of elderly those who have demand for an oral hygiene service were willing to pay for the service, and 64 people (91.4%) who did not have a demand were not willing to pay for it. Among those with partial dependence on brushing, 65.6% had demand for oral hygiene services and 50.0% were willing to pay costs. Among basic livelihood beneficiaries, 69.6% were willing to pay for oral hygiene services; general subjects and relievers were less willing to pay. CONCLUSIONS: The overall demand for oral hygiene services among elderly people was 44.4%, and the willingness to pay was as low as 31.0%.

BACKGROUND/AIMS: The meaning of specialized intestinal metaplasia (SIM) in the diagnosis of Barrett's esophagus (BE) is not clear. This study was designed to determine the clinical significance of SIM in the diagnosis of Barrett's esophagus. MATERIALS AND METHODS: Biopsies were taken from 601 subjects with endoscopically suspected columnar-lined esophagus. Under light microscopy with Alcian-blue stain, SIM was identified. Demographic characteristics, gastroesophageal (GE) reflux symptoms and endoscopic findings were compared between the SIM-present group and the SIM-absent group. RESULTS: Among 601 subjects, 184 (30.6%) were confirmed by pathology to have SIM. Age over 40 years (P<0.001) and a medication history of proton pump inhibitor or H2 blocker were found more frequently in the SIM-present group (P=0.01) than in the SIM-absent group. Any of 7 GE reflux symptoms (heartburn, acid regurgitation, chest pain, hoarseness, globus sensation, cough and epigastric soreness) were more frequent in the SIM-present group than SIM-absent group (P<0.001). Specifically, heartburn, chest pain and cough were significantly more common in the SIM-present group. There was no clinically significant difference associated with endoscopic findings or other clinical characteristics. CONCLUSIONS: When subjects with endoscopically suspected BE are analyzed based on the presence or absence of SIM, the SIM-present group was significantly associated with GE reflux symptoms suggestive of frequent GE reflux. However, the presence of SIM did not correlate with endoscopic findings.

BACKGROUND: The present study was aimed at investigating the predictive parameters of erythropoietin (epoetin) hyporesponsiveness in patients on continous ambulatory peritoneal dialysis (CAPD). METHODS: We studied 40 patients with end-stage renal disease who had been receiving CAPD for at least 6 months and epoetin therapy for at least more than 2 months. Pearson's simple correlation and multiple stepwise linear regression analysis was used to discover what parameter can predict epoetin resistance. We expressed epoetin resistance index (ERI) as 'weekly epoetin dose/hematocrit/ body weight'. The dose of epoetin is titrated by about 25% every 2 to 4 weeks to maintain a target hematocrit level between 33% and 36%. RESULTS: We analyzed the relationship between ERI and other predictive parameters by Pearson's correlation. These results showed ERI has a statistically significant correlation with transferrin saturation (TS) (r=-0.327, p=0.042), total weekly Kt/Vurea (r=-0.423, p=0.018), serum albumin level (r=-0.458, p= 0.003), normalized protein catabolic rate (nPCR) (r=-0.479, p=0.006), normalized protein equivalent of total nitrogen appearance (nPNA) (r=-0.488, p=0.005) and serum C-reactive protein (CRP) (r=0.332, p=0.036). Regression analysis was performed using stepwise linear regression for multiple variables to discover the most independent variable which is correlated with ERI. ERI was entered as a dependent variable, whereas the other parameters (age, duration of peritoneal dialysis, serum albumin level, CRP, serum ferritin, total weekly Kt/Vurea, nPCR, nPNA, serum iPTH, serum aluminium, TS) were entered as independent variables. This analysis showed CRP is the most significant variable and, if CRP is excluded, nPNA is the significant variable. CRP has a statistically significant correlation with serum albumin level (r=-0.418, p=0.007) and total weekly Kt/Vurea (r=-0.366, p=0.043). High CRP group has more increased level of ERI (p<0.05), age (p<0.05) and serum creatinine level (p<0.05) than normal control, but more decreased level of serum albumin (p<0.01) and serum iron levels (p<0.05). CONCLUSION: These results indicate that CRP is the most important predictor of epoetin hyporesponsiveness.
