Purpose: Periprosthetic joint infections (PJIs) resulting from total hip arthroplasty (THA) pose significant challenges. Partial two-stage exchange arthroplasty (TSEA) retains either the femoral stem or acetabular cup by preserving bone stock and soft tissue and offers a potential alternative to total TSEA. Our meta-analysis evaluated the pooled success rate of partial TSEA in treating late chronic PJIs in THA. Our study also focused on the outcomes associated with retained prosthetic implant (stem or cup) and the type of prior surgery (primary vs. revision arthroplasty) performed. Materials and Methods: We analyzed data from 355 hips of patients with PJI following THA across 11 studies using a random-effects model to estimate the success rate of partial TSEA and spacer dislocation that occurs during the interval between the first and second stages of partial TSEA. The heterogeneity between the subgroups was also calculated. Results: The overall pooled success rate of partial TSEA in the study cohort was 87% (95% confidence interval [CI] 83-91).Lacking statistical significance (P=0.904), the success rates were 88% for stem-retained and 90% for cup-retained implant cases. The partial TSEA success rates were 88% for primary arthroplasty and 80% for revision arthroplasty, although this was not statistically significant (P=0.193). Spacer dislocation occurred in only 5% of the cases (95% CI 1-9). Conclusion Partial TSEA achieves high success rates comparable to those of total TSEA. Although revision arthroplasty cases carry a high risk of recurrence, partial TSEA remains a viable, tailored treatment option with a low complication rate.

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.

BACKGROUND/OBJECTIVES: Perceived diet quality (PDQ) has been suggested as an easy-touse dietary assessment tool. However, its practicality and efficiency are still questionable.This study aimed to gauge the utility of PDQ as an alternative dietary assessment tool among Korean adults by examining PDQ and its associated factors. SUBJECTS/METHODS: An online survey was conducted on 514 Korean adults aged 19 to 64 years in October 2022. PDQ was assessed using a 5-point Likert scale, and participants were categorized into healthy, fair, or unhealthy PDQ groups. The participants were asked about the perceived importance of nutrients and food groups for health and the extent to which they considered these factors in their usual diets using a 5-point Likert scale. A multivariate linear regression model was used to identify the factors associated with PDQ. RESULTS: About 26.7% of participants rated their diets as healthy, while 63.2% rated them as fair and 10.1% rated them as unhealthy. Participants with a healthy PDQ rated perceived importance and consideration of nutrients and food groups higher than the fair or unhealthy PDQ groups. A healthier PDQ was associated with the male gender, an older age, being normal or underweight, having better subjective health, lower use of alcohol, being physically active, having a high interest in healthy diets, and a higher perception of the importance of nutrients and food groups for health. CONCLUSION The PDQ could serve as a simple and rapid screening tool for identifying individuals at risk of poor diets.

Purpose: This study aimed to compare the short-term outcomes and safety profiles of androgen-deprivation therapy (ADT)+abiraterone/prednisone with those of ADT+docetaxel in patients with de novo metastatic hormone-sensitive prostate cancer (mHSPC). Materials and Methods: A web-based database system was established to collect prospective cohort data for patients with mHSPC in Korea. From May 2019 to November 2022, 928 patients with mHSPC from 15 institutions were enrolled. Among these patients, data from 122 patients who received ADT+abiraterone/prednisone or ADT+docetaxel as the primary systemic treatment for mHSPC were collected. The patients were divided into two groups: ADT+abiraterone/prednisone group (n=102) and ADT+docetaxel group (n=20). We compared the demographic characteristics, medical histories, baseline cancer status, initial laboratory tests, metastatic burden, oncological outcomes for mHSPC, progression after mHSPC treatment, adverse effects, follow-up, and survival data between the two groups. Results: No significant differences in the demographic characteristics, medical histories, metastatic burden, and baseline cancer status were observed between the two groups. The ADT+abiraterone/prednisone group had a lower prostate-specific antigen (PSA) progression rate (7.8% vs. 30.0%; p=0.011) and lower systemic treatment discontinuation rate (22.5% vs. 45.0%; p=0.037). No significant differences in adverse effects, oncological outcomes, and total follow-up period were observed between the two groups. Conclusions ADT+abiraterone/prednisone had lower PSA progression and systemic treatment discontinuation rates than ADT+docetaxel. In conclusion, further studies involving larger, double-blinded randomized trials with extended follow-up periods are necessary.

Selective cannulation during endoscopic retrograde cholangiopancreatography can be particularly challenging when the papilla is invisible, either due to an intradiverticular papilla (IDP) or because it is covered by a mucosal fold. Endoclipassisted cannulation is an effective and safe technique for everting and fixing the papilla and it can be used alone or in combination with other devices. In this report, we achieved successful papillary cannulation in two cases of IDP and one case where the papilla was covered by a mucosal fold. In two cases, cannulation was accomplished by repositioning the invisible papilla using an endoclip alone, while in one case, we used an endoclip-assisted technique to push a redundant fold with a catheter. Endoclipassisted papillary cannulation can be applied in different situations, either alone or in combination with other devices.

Background: It has become important to identify and manage risk factors for subclinical atrial fibrillation (AF) with an increase in its detection rate. Thus, this research aimed to investigate whether alcohol consumption contrib‑ utes to the development of subclinical AF. Methods: This prospective study enrolled 467 patients without AF from a multicenter pacemaker registry. The incidence of subclinical AF (episodes of atrial rate > 220 beats per minute without symptoms) was compared between alcohol-drinking and non-drinking groups. Results: During followup (median 18 months), the incidence and risk of long-duration atrial high-rate episodes (AHRE) ≥ 24 h were increased in the alcohol group compared to the non-alcohol group [5.47 vs. 2.10 per 100 personyears, adjusted hazard ratio (HR), 2.83; 95% confidence interval (CI), 1.14–7.04; P = 0.03]. After propensity score match‑ ing, the incidence and risk of long-duration AHRE were higher in the alcohol group (6.97 vs. 1.27 per 100 personyears, adjusted HR, 7.84; 95% CI, 1.21–50.93; P = 0.03). The mean burden of long-duration subclinical AF was higher in the alcohol group than in the non-alcohol group (0.18 vs. 1.61% during follow-up, P = 0.08). Conclusion Alcohol consumption was associated with an increased risk of subclinical AF. Long-duration AHRE inci‑ dence and AHRE burden were higher in alcohol drinkers than in non-drinkers.
