RESUMEN
BACKGROUND: During the COVID-19 pandemic, urban inhabitants faced significant challenges in maintaining connections with nature, adhering to nutritional guidelines, and managing mental well-being. OBJECTIVE: Recognizing the urgent need for innovative approaches, this study was designed to explore the potential benefits of a specific digital intervention, the rice-farming simulation game Sakuna: Of Rice and Ruin, for nature relatedness, nutritional behaviors, and psychological well-being. METHODS: A total of 66 adults without any prior major psychiatric disorders residing in an urban area were recruited for the study. They were randomly assigned to 2 groups through block randomization: the immediate intervention group (IIG; 34/66, 52%) and the waitlist group (32/66, 48%). Participants in the IIG were instructed to play the game for at least 4 days per week for 3 weeks, with each session lasting from 30 minutes to 3 hours. Assessments were performed at baseline, week 1, and week 3. The Nature Relatedness Scale (NR) and Nutrition Quotient Scale were used to evaluate nature relatedness and nutritional state, respectively. Furthermore, psychological state was assessed using the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF), Brief Fear of Negative Evaluation Scale, Social Avoidance and Distress Scale, Toronto Alexithymia Scale, State-Trait Anxiety Inventory, Center for Epidemiologic Studies Depression Scale Revised, and Korean Resilience Quotient. RESULTS: This study's results revealed significant time interactions between the IIG and waitlist group for both the total NR score (P=.001) and the score of the self subdomain of NR (P<.001), indicating an impact of the game on nature relatedness. No group×time interactions were found for the total Nutrition Quotient Scale and subdomain scores, although both groups showed increases from baseline. For psychological state, a significant group×time interaction was observed in the total WHOQOL-BREF score (P=.049), suggesting an impact of the game on quality of life. The psychological (P=.01), social (P=.003), and environmental (P=.04) subdomains of the WHOQOL-BREF showed only a significant time effect. Other psychological scales did not display any significant changes (all P>.05). CONCLUSIONS: Our findings suggest that the rice-farming game intervention might have positive effects on nature relatedness, nature-friendly dietary behaviors, quality of life, anxiety, depression, interpersonal relationships, and resilience among urban adults during the COVID-19 pandemic. The impact of pronature games in confined urban environments provides valuable evidence of how digital technologies can be used to enhance urban residents' affinity for nature and psychological well-being. This understanding can be extended in the future to other digital platforms, such as metaverses.

BACKGROUND: The pathophysiology of frozen shoulder (FS) involves abnormal expressions of matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) that lead to capsular fibrosis. However, there has been little concern for why diabetic FS has more protracted fibrotic condition. The objective of this study was to compare the expression levels of MMPs and TIMPs in the joint capsule of patients with diabetic and nondiabetic FS. MATERIALS AND METHODS: Samples of capsular tissue were collected from 20 patients with FS (10 diabetic patients; diabetic group and 10 nondiabetic patients; nondiabetic group) and 10 patients (control group) with chronic anterior shoulder instability. Quantitative real-time reverse transcriptase-polymerase chain reaction and Western blot analysis were performed to determine the expression levels of mRNA and protein for MMP-1, 3, 9, 13, 14, and TIMP-1, 2. RESULTS: The results of quantitative real-time reverse transcriptase-polymerase chain reaction showed significantly higher expression levels of all MMPs and TIMP-1 and significantly lower expression levels of TIMP-2 in the joint capsule of patients in the diabetic or nondiabetic groups compared with the control group. Significantly higher expression levels of MMP-1, 9, 14, and TIMP-1 were detected in the diabetic group compared with the nondiabetic group. The results of Western blot analysis showed significantly higher levels of MMP-3, 13, 14, and TIMP-1 in the joint capsule of patients in the diabetic or nondiabetic groups compared with the control group. However, no significant differences of protein levels of them were observed between diabetic and nondiabetic groups. CONCLUSIONS: The findings of this study demonstrate the potential involvement of MMP-1 and 9 in the pathophysiology of diabetic FS. These findings may be helpful in identification of therapeutic targets for development of novel treatments for this protracted chronic fibrosing condition.
RESUMEN
BACKGROUND: The aim of this study was to compare outcomes and complications in patients with and without a history of prior rotator cuff surgery who underwent reverse total shoulder arthroplasty (RTSA). METHODS: Two-hundred and nine consecutive patients who had undergone RTSA for rotator cuff insufficiency with a minimum 12-months follow-up period were reviewed. A total of 35 patients with a history of prior rotator cuff surgery were made the study group (PS group). Using propensity score matching for age and sex, these patients were matched 1:3 with a control group of 105 patients with no history of prior surgery (NPS group). The mean follow-up period was 41.4 months. RESULTS: Both groups showed a significant improvement of clinical scores and range of motion after RTSA. The PS group showed a significantly higher final visual analog scale (VAS) pain score compared with the NPS group (P = 0.020). The PS group showed a significantly higher incidence of acromial stress fracture compared with the NPS group (17.1% vs 4.8%, P = 0.018), but no significant difference in the overall complication rate was observed (25.7% vs 13.3%, P > 0.05). The PS group showed a significantly higher reoperation rate compared with the NPS group (14.3% vs 1.9%, P = 0.004). CONCLUSIONS: Our study demonstrated that a history of prior rotator cuff surgery was associated with a high incidence of acromial stress fracture and reoperation after RTSA as well as a high final VAS pain score, although satisfactory clinical outcomes after RTSA were achieved in both groups.
RESUMEN
BACKGROUND: Mood disorders require consistent management of symptoms to prevent recurrences of mood episodes. Circadian rhythm (CR) disruption is a key symptom of mood disorders to be proactively managed to prevent mood episode recurrences. This study aims to predict impending mood episodes recurrences using digital phenotypes related to CR obtained from wearable devices and smartphones. METHODS: The study is a multicenter, nationwide, prospective, observational study with major depressive disorder, bipolar disorder I, and bipolar II disorder. A total of 495 patients were recruited from eight hospitals in South Korea. Patients were followed up for an average of 279.7 days (a total sample of 75 506 days) with wearable devices and smartphones and with clinical interviews conducted every 3 months. Algorithms predicting impending mood episodes were developed with machine learning. Algorithm-predicted mood episodes were then compared to those identified through face-to-face clinical interviews incorporating ecological momentary assessments of daily mood and energy. RESULTS: Two hundred seventy mood episodes recurred in 135 subjects during the follow-up period. The prediction accuracies for impending major depressive episodes, manic episodes, and hypomanic episodes for the next 3 days were 90.1, 92.6, and 93.0%, with the area under the curve values of 0.937, 0.957, and 0.963, respectively. CONCLUSIONS: We predicted the onset of mood episode recurrences exclusively using digital phenotypes. Specifically, phenotypes indicating CR misalignment contributed the most to the prediction of episodes recurrences. Our findings suggest that monitoring of CR using digital devices can be useful in preventing and treating mood disorders.

BACKGROUND: This study estimated the association between pre-pandemic social network properties and symptoms of posttraumatic stress during the coronavirus disease 2019 (COVID-19) pandemic in South Korea. METHODS: We conducted four online mental health surveys during COVID-19 (from March 14, 2020, to December 11, 2021) among individuals enrolled in a community-based cohort study (previously recruited from 2013 to 2018). Among 4060 people interviewed at the pre-pandemic baseline, 2652 individuals (men = 951, women = 1701) who responded to at least one of the four surveys conducted were included. At baseline, each individual's social network, including size and average closeness, was measured in an egocentric way. Post Traumatic Stress Disorder Checklist for DSM-5 (PCL-5) was measured at each survey point. A generalized linear model and a generalized linear mixed model were used after stratified by sex. RESULTS: Among men, network size was negatively associated with total PCL-5 score (b = -0.42, SE = 0.16, p = 0.002). The magnitude of the association increased over time and was maximal by the 4th survey (b = -0.65, SE = 0.31, p = 0.037). Among women, average closeness was negatively associated with the total PCL-5 score (b = -1.16, SE = 0.37, p = 0.002). In analyses disaggregated by symptom clusters, social networks were associated explicitly with symptoms of intrusion and mood but not with avoidance and arousal symptoms. CONCLUSION: In this cohort of adults followed for more than a year during the outbreak of COVID-19 in South Korea, social networks established before the onset of the COVID-19 pandemic had a protective association against developing symptoms of PTSD during the first two years of the pandemic.

BACKGROUND: The purpose of this study was to investigate sequential changes of emotional status and quality of life after reverse shoulder arthroplasty (RSA) for rotator cuff insufficiency and to determine the predictors that can affect postoperative clinical outcomes. This study was conducted to prove the hypothesis that RSA would improve emotional status and quality of life. METHODS: Fifty patients undergoing RSA for rotator cuff insufficiency were prospectively included. Evaluation using the visual analog scale pain score, American Shoulder and Elbow Surgeons (ASES) score, subjective shoulder value, Hospital Anxiety and Depression Scale (HADS), and Abbreviated scale of World Health Organization Quality of Life (WHOQOL-BREF) was performed before surgery and at 1.5, 3, 6, and 12 months after surgery. RESULTS: The mean visual analog scale pain score, HADS-depression score, and HADS-anxiety score showed a significant decrease from 6.6, 13.3, and 13.9 before surgery to 1.5, 3.9, and 3.7 after 12 months after surgery, respectively (all P < .001). The mean ASES score, WHOQOL-BREF score, and subjective shoulder value showed a significant improvement from 28.5, 32.3, and 23.6% to 81.3, 79.1, and 78.4%, respectively (all P < .001). All outcome measurements showed a significant improvement from 6 weeks after RSA. In multivariate analysis, age was an independent predictor of the final ASES score and WHOQOL-BREF score (P = .037 and .004, respectively). CONCLUSION: This study showed a sequential improvement of emotional status and quality of life as well as functional recovery with pain relief from 6 weeks after RSA in patients with rotator cuff insufficiency. Especially, younger patients had better postoperative functional ability and quality of life. These findings suggest that RSA for rotator cuff insufficiency provides a rapid improvement of emotional status and quality of life.

BACKGROUND: The purpose of this study was to investigate the outcomes and complications of hemiarthroplasty (HA) and total shoulder arthroplasty (TSA) in patients of osteonecrosis of humeral head (ONHH) through systematic review. METHODS: PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) guidelines were followed by utilizing the PubMed, EMBASE, Scopus, Ovid, and Cochrane Library databases. Keywords included ONHH, avascular necrosis, head replacement, hemiarthroplasty, or total shoulder arthroplasty. Methodological Index for Nonrandomized Studies (MINORS) was used for quality assessment. RESULTS: Ten studies (416 shoulders) were finally eligible and mean MINORS score was 11.9 (ranges, 8-16). HA was performed in 255 shoulders (61.3%) and TSA in 161 (38.7%). Mean age of the patients at the time of surgery was 50.6 years and mean follow-up period was 73.1 months. All clinical scores with range of motion were significantly improved after surgery. Overall complication rate was 20.0% with 10.1% in HA and 17.5% in TSA (p = 0.077). Overall reoperation rate was 11.2% with 7.0% in HA and 15.0% in TSA (p = 0.046). Overall revision rate was 6.4% with 5.7% in HA and 9.2% in TSA (p = 0.349). CONCLUSIONS: Both HA and TSA in patients with ONHH yielded functional improvement with pain relief, but TSA had higher reoperation rate compared to HA.

BACKGROUND: Fracture of the anteromedial facet (AMF) of the coronoid process is associated with varus posteromedial rotatory instability (VPMRI). However, there is still controversy regarding the optimal treatment for AMF fracture. The purpose of this study is to report on a systematic review of the outcomes and complications after treatment for AMF fracture. METHODS: This study was conducted using electronic databases, PubMed, EMBASE and Scopus. Studies reporting outcome scores and complications were included. Studies that did not utilize O'Driscoll classification for AMF fractures were excluded. Through conduct of a thorough review of included studies, definite VPMRI were identified and cases involving other injury mechanisms were excluded. RESULTS: Fifteen articles reporting on 246 patients were included. According to O'Driscoll classification, 6.2% of cases were anteromedial subtype I, 73.7% were subtype II, and 20.1% were subtype III. Two-hundred sixteen patients (87.8%) were treated surgically and 30 patients (12.2%) were treated conservatively. Lateral collateral ligament (LCL) injuries were 76.2% (157/206) and medial collateral ligament injuries were 16.9% (33/195). Among 216 cases who underwent surgical treatment, depending on the fragment size, displacement, and instability, coronoid fixation was performed in 189 cases and LCL repair alone was performed in 27 cases. The mean final Mayo Elbow Performance Score was 92.1 and the Broberg & Morrey score was 89.5. The overall complication and reoperation rates were 17.7% (41/232) and 12.9% (26/202). CONCLUSIONS: Both surgical and conservative treatment for AMF fractures resulted in satisfactory final clinical outcomes. However, high complication and reoperation rates were observed.
RESUMEN
INTRODUCTION: The purpose of this study was to compare the outcomes and complications after humeral head replacement (HHR) and total shoulder replacement (TSR) in patients with osteonecrosis of the humeral head (ONHH). MATERIALS AND METHODS: Twenty-six patients who underwent shoulder replacement (13 HHRs and 13 TSRs) for nontraumatic ONHH were included. The mean follow-up period was 96.4 months. The visual analog scale (VAS) pain score, the University of California at Los Angeles (UCLA) score, the American Shoulder and Elbow Surgeon (ASES) score, and range of motion (ROM) at the final follow-up evaluation were used for the assessment of clinical outcomes. RESULTS: The mean VAS pain score, UCLA score, and ASES score showed significant improvement from 6.3, 11.6, and 35.0 before surgery to 2.2, 28.9, and 82.6 at the final follow-up evaluation (all p < 0.001). No significant differences regarding all clinical scores and ROMs were observed between the HHR group and the TSR group, except that a greater abduction angle was observed in the HHR group compared with the TSR group (123.1° versus 96.9°, p = 0.014). Two patients in the TSR group underwent multiple reoperations due to periprosthetic joint infection. No revision surgeries were performed for glenoid erosion following HHR or aseptic glenoid loosening following TSR. CONCLUSIONS: The findings of this study showed satisfactory clinical and radiological outcomes with implant longevity for both HHR and TSR in patients with nontraumatic ONHH. The HHR group had a greater abduction angle compared with the TSR group.

PURPOSE: The purpose of this study was to investigate the incidence, characteristics, and risk factors for venous thromboembolism (VTE) in patients who underwent shoulder arthroplasty (SA) through systematic review. METHODS: A search of studies was conducted using the databases for PubMed, EMBASE, Scopus, Ovid, MEDLINE, and Cochrane Library according to the guidelines for PRISMA (Preferred Reporting Items for Systematic Meta-Analyses). Quality assessment was performed using the Methodological Index for Nonrandomized Studies (MINORS). RESULTS: Nine studies (12,566 shoulders) were finally eligible and the mean MINORS score was 13.2 (ranges, 9-18). The overall incidence of VTE was 0.81% (78/9681) including 0.54% (52/9681) for deep vein thrombosis (DVT) and 0.33% (42/12,566) for pulmonary embolism (PE). There were no significant differences in the incidences according to the type of arthroplasty. DVT was detected at an average of 18.8 days after index surgery, and PE was detected at an average of 12.7 days after index surgery. The risk factors for VTE included age older than 70 years, higher BMI, raised Charlson Comorbidity Index, history of DVT, asthma, cardiac arrhythmia, diabetes, lower haemoglobin level, use of general endotracheal anaesthesia without interscalene nerve block, traumatic indication, longer operative time, and revision SA. The mortality rate was 4.1% (2/49) for VTE and 8.3% (2/24) for PE. CONCLUSION: Despite the fact that the overall incidence of VTE following SA was as low as 0.81%, shoulder surgeons should consider the potential for this serious complication in high-risk patients. Further well-designed large-scale studies are necessary to clarify the consensus for VTE after SA including risk factors, treatment, and prophylaxis.

Background and Objectives: The aim of this study was to evaluate whether device removal in symptomatic patients following locking plate osteosynthesis of a proximal humerus fracture improves the clinical outcomes. Materials and Methods: Seventy-one patients who underwent fixed-angle locking plate osteosynthesis of a proximal humerus fracture were included. Thirty-three patients underwent device removal at a mean time of 10.4 months after index surgery (removal group). Thirty-eight patients who retained the device after index surgery (retention group) were included in the control group. Visual analog scale (VAS) pain score, University of California at Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM) were evaluated pre- and postoperatively. Results: At the final follow-up, mean UCLA score, ASES score, and all ROMs were significantly higher in the removal group compared to the retention group (p < 0.001). However, no significant difference in mean VAS pain score was observed between the two groups. Comparison of the clinical outcomes before and after device removal surgery showed significant improvement in all clinical scores and ROMs after device removal (p < 0.001). Conclusions: Device removal surgery in symptomatic patients following locking plate osteosynthesis of a proximal humerus fracture can result in significant improvement in functional outcomes.

BACKGROUND: Many mood disorder patients experience seasonal changes in varying degrees. Studies on seasonality have shown that bipolar disorder has a higher prevalence rate in such patients; however, there is limited research on seasonality in early-onset mood disorder patients. This study estimated the prevalence of seasonality in early-onset mood disorder patients, and examined the association between seasonality and mood disorders. METHODS: Early-onset mood disorder patients (n = 378; 138 major depressive disorder; 101 bipolar I disorder; 139 bipolar II disorder) of the Mood Disorder Cohort Research Consortium and healthy control subjects (n = 235) were assessed for seasonality with Seasonality Pattern Assessment Questionnaire (SPAQ). RESULTS: A higher global seasonality score, an overall seasonal impairment score, and the prevalence of seasonal affective disorder (SAD) and subsyndromal SAD showed that mood disorder subjects had higher seasonality than the healthy subjects. The former subject group had a significantly higher mean overall seasonal impairment score than the healthy subjects (p < .001); in particular, bipolar II disorder subjects had the highest prevalence of SAD, and the diagnosis of bipolar II disorder had significantly higher odds ratios for SAD when compared to major depression and bipolar I disorder (p < .05). CONCLUSIONS: Early-onset mood disorders, especially bipolar II disorder, were associated with high seasonality. A thorough assessment of seasonality in early-onset mood disorders may be warranted for more personalized treatment and proactive prevention of mood episodes.

BACKGROUND: Attempts to use virtual reality (VR) as a treatment for various psychiatric disorders have been made recently, and many researchers have identified the effects of VR in psychiatric disorders. Studies have reported that VR therapy is effective in social anxiety disorder (SAD). However, there is no prior study on the neural correlates of VR therapy in patients with SAD. OBJECTIVE: The aim of this study is to find the neural correlates of VR therapy by evaluating the treatment effectiveness of VR in patients with SAD using portable functional near-infrared spectroscopy (fNIRS). METHODS: Patients with SAD (n=28) were provided with 6 sessions of VR treatment that was developed for exposure to social situations with a recording system of each participant's self-introduction in VR. After each VR treatment session, the first-person view (video 1) and third-person view (video 2) clips of the participant's self-introduction were automatically generated. The functional activities of prefrontal regions were measured by fNIRS while watching videos 1 and 2 with a cognitive task, before and after whole VR treatment sessions, and after the first session of VR treatment. We compared the data of fNIRS between patients with SAD and healthy controls (HCs; n=27). RESULTS: We found that reduction in activities of the right frontopolar prefrontal cortex (FPPFC) in HCs was greater than in the SAD group at baseline (t=-2.01, P=.049). Comparing the frontal cortex activation before and after VR treatment sessions in the SAD group showed significant differences in activities of the FPPFC (right: t=-2.93, P<.001; left: t=-2.25, P=.03) and the orbitofrontal cortex (OFC) (right: t=-2.10, P=.045; left: t=-2.21, P=.04) while watching video 2. CONCLUSIONS: Activities of the FPPFC and OFC were associated with symptom reduction after VR treatment for SAD. Our study findings might provide a clue to understanding the mechanisms underlying VR treatment for SAD.

PURPOSE: The purposes of this study were to (1) evaluate changes in recovery patterns [i.e., clinical outcomes, range of motion (ROM)] in the first 12 months following surgery, (2) identify potential prognostic factors of early clinical outcomes after rotator cuff repair (RCR). METHODS: The study cohort included 344 consecutive patients treated with RCR. Data were collected prospectively and included pre- and perioperative variables. Univariate and multivariate linear regression analyses for various parameters including demographics, pre- and perioperative variables were used to predict shoulder function at 12-month follow-up, as measured by clinical outcomes and ROM. RESULTS: Significant improvement in all clinical scores and ROM were noted during serial follow-ups after RCR (all p < 0.001). Multivariate analysis revealed that female sex, older age, more anchors, diabetes mellitus, and preoperative stiffness were independently associated with worse shoulder function 3 months after RCR. Including the 3 months factors, heavy labor, use of the suture-bridge technique, and large tears were also independently associated with worse outcomes 6 months after surgery. Heavy labor, suture-bridge technique, diabetes mellitus, and preoperative stiffness were associated with significantly worse functional outcomes at 12 months after surgery (all p < 0.05). CONCLUSION: Functional recovery based on clinical outcomes (i.e., UCLA, ASES scores) showed approximately 60% of ultimate recovery at 3 months and approximately 75% recovery at 6 months after RCR. Female sex, diabetes mellitus, preoperative stiffness, a larger number of anchors, suture bridge technique, heavy labor, old age and, larger tears were prognostic factors of poor clinical results or ROM in the short-term follow-up intervals. Knowledge of these prognostic factors may lead to improved insight for physicians to predict the pattern of the recovery and patient expectations accordingly. LEVEL OF EVIDENCE: III, A cohort study.

INTRODUCTION: The purpose of this study was to classify the injury mechanism of terrible triad (TT) and suggest a treatment method according to the mechanism. MATERIALS AND METHODS: Forty TTs with magnetic resonance imaging (MRI) scans and 3-dimensional computed tomography (3D CT) were enrolled. 3D CT scans of coronoid fractures were used for classifying into O'Driscoll type representing injury mechanisms and measuring sizes. In MRI scans, lateral collateral ligament complex (LCLC) injuries were classified into distraction (D) type caused by varus force and stripping (S) type caused by forearm external rotation force. Using these findings, possible injury mechanisms were speculated and classified into groups. Characteristic soft tissue injury patterns of collateral ligaments and overlying muscles, direction of dislocation in simple radiographs, and the amount of involvement of radial head fracture were investigated. Ulnar- and radial-side instabilities of soft tissues were newly defined and investigated. RESULTS: There were 29 (73%) cases by posterolateral external rotation (PLER), 5 (13%) cases by posteromedial external rotation (PMER), and 6 (14%) cases by posteromedial internal rotation (PMIR). Simple radiographs showed all posterolateral dislocations in PLER TT compared to posteromedial or pure posterior dislocations in PMER or PMIR TT. Regarding LCLC and overlying extensor muscle, they were all completely torn with D type in all PLER compared to D type in PMER or PMIR. The ulnar collateral ligament was spared in 5 (17%) cases among 29 PLER in contrast to complete rupture in all PMER and PMIR. In PLER, PMER, and PMIR, involvement ratios of radial head fracture were 82% (range, 27%-100%), 61% (range, 25%-100%), and 61% (range, 25%-100%), respectively, and sizes of coronoid fractures were 7 mm (range, 1-14 mm), 6 mm (range, 2-11 mm), and 10 mm (range, 2-16 mm), respectively. In PLER, PMER, and PMIR, percentages of ulnar-side instabilities were 17%, 20%, and 17%, respectively, and those of radial-side instabilities were 59%, 60%, and 83%, respectively. CONCLUSIONS: TT is caused by at least 3 mechanisms (PLER, PMER, and PMIR) with characteristic soft tissue injuries and fracture patterns. PLER is the main mechanism of injury. It is always observed in the form of posterolateral dislocation on simple radiographs compared with pure posterior or posteromedial dislocation of PMER or PMIR. It should be managed individually based on injury mechanisms presenting different instability patterns.

BACKGROUND: The occurrence and related predictors of acromial fracture following reverse total shoulder arthroplasty (RTSA) have not been fully elucidated. The aim of this study was to determine the incidence and risk factors of acromial fractures after RTSA. METHODS: We conducted a multicenter, retrospective case-control study of 787 cases (29 in acromial fracture group and 758 in control group) that underwent RTSA performed by 6 surgeons. The mean duration of follow-up after RTSA was 31.6 ± 21.8 months (range, 12-136 months). Demographic variables (age, sex, arm dominance, body mass index, working status, bone mineral density [BMD]), clinical variables (preoperative diagnosis, previous operation, implant design, preoperative clinical scores, screw size in glenoid fixation, postoperative rehabilitation), and radiographic variables (acromial thickness, critical shoulder angle, deltoid length, humeral offset to lateral acromion) were investigated. To determine risk correlation, univariate analysis and multivariate logistic regression analysis with calculated odds ratios (ORs) were performed. RESULTS: Postoperative acromial fractures occurred in 29 of the 787 shoulders with RTSA (3.7%). Acromial fractures were detected at a mean of 10.0 months (range, 1-66 months) postoperatively. Univariate analysis revealed that the occurrence of an acromial fracture was significantly associated with a previous operation (38% [11 of 29] vs. 21% [156 of 758], P = .025) and BMD (-2.33 vs. -1.74, P = .013). Multivariate logistic regression analysis found that the occurrence of a postoperative acromial fracture was significantly associated with a previous operation (P = .034; OR, 2.91; 95% confidence interval, 1.08-7.84) and deltoid length (P = .004; OR, 1.04; 95% confidence interval, 1.01-1.07). CONCLUSION: Acromial fracture following RTSA is not an uncommon complication, with an overall incidence of 3.7%. A previous operation, increased deltoid length, and low BMD were risk factors of acromial fracture following RTSA.

BACKGROUND: Although recipients and donors in living kidney transplantation experience psychological distress-including depression and anxiety-during the pre-operative period, very few studies have evaluated the related psychological reactions. This study aimed to determine the characteristics and correlations of the mood states and personality of recipients and donors (genetically related and unrelated) of living kidney transplantations. METHODS: A total of 66 pairs of living donors and recipients were enrolled from April 2008 to June 2019 in this study, of whom 53 eligible pairs of living donors and recipients were included in the retrospective analysis of their psychological assessments in the pre-transplantation states. While participants' personality patterns were assessed using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), mood states were evaluated via both the State-Trait Anxiety Inventory (STAI) and The Center for Epidemiologic Studies Depression Scale (CES-D). Statistical analysis was performed using paired t-tests and Spearman's correlation analyses. RESULTS: The recipient group showed significantly higher scores for Hypochondriasis (t = - 4.49, p = .0001), Depression (t = - 3.36, p = .0015), and Hysteria (t = - 3.30, p = .0018) of MMPI-2 and CES-D (t = - 3.93, p = .0003) than the donor group. The biologically unrelated recipient group reported higher scores of Hypochondriasis (t = - 3.37, p = .003) and Depression (t = - 2.86, p = 0.0098) than the unrelated donor group. Higher scores for Hypochondriasis (t = - 3.00, p = 0.0054) and CES-D (t = - 3.53, p = .0014) were found in the related recipient group. A positive association was found for Hypomania (r = .40, p = .003) of MMPI-2, STAI-S (r = .36, p = .009), and CES-D (r = .36, p = .008) between the recipient and donor groups. CONCLUSIONS: Recipients suffered from a higher level of depression and somatic concerns than donors before living kidney transplantation. Psychological problems like depression and anxiety can occur in both living kidney transplantation donors and recipients. This study suggests that clinicians must pay attention to mood states not only in recipients but also in donors because of emotional contagion.

BACKGROUND: Social anxiety disorder (SAD) is characterized by excessive fear of negative evaluation and humiliation in social interactions and situations. Virtual reality (VR) treatment is a promising intervention option for SAD. OBJECTIVE: The purpose of this study was to create a participatory and interactive VR intervention for SAD. Treatment progress, including the severity of symptoms and the cognitive and emotional aspects of SAD, was analyzed to evaluate the effectiveness of the intervention. METHODS: In total, 32 individuals with SAD and 34 healthy control participants were enrolled in the study through advertisements for online bulletin boards at universities. A VR intervention was designed consisting of three stages (introduction, core, and finishing) and three difficulty levels (easy, medium, and hard) that could be selected by the participants. The core stage was the exposure intervention in which participants engaged in social situations. The effectiveness of treatment was assessed through Beck Anxiety inventory (BAI), State-Trait Anxiety Inventory (STAI), Internalized Shame Scale (ISS), Post-Event Rumination Scale (PERS), Social Phobia Scale (SPS), Social Interaction Anxiety Scale (SIAS), Brief-Fear of Negative Evaluation Scale (BFNE), and Liebowitz Social Anxiety Scale (LSAS). RESULTS: In the SAD group, scores on the BAI (F=4.616, P=.009), STAI-Trait (F=4.670, P=.004), ISS (F=6.924, P=.001), PERS-negative (F=1.008, P<.001), SPS (F=8.456, P<.001), BFNE (F=6.117, P=.004), KSAD (F=13.259, P<.001), and LSAS (F=4.103, P=.009) significantly improved over the treatment process. Compared with the healthy control group before treatment, the SAD group showed significantly higher scores on all scales (P<.001), and these significant differences persisted even after treatment (P<.001). In the comparison between the VR treatment responder and nonresponder subgroups, there was no significant difference across the course of the VR session. CONCLUSIONS: These findings indicated that a participatory and interactive VR intervention had a significant effect on alleviation of the clinical symptoms of SAD, confirming the usefulness of VR for the treatment of SAD. VR treatment is expected to be one of various beneficial therapeutic approaches in the future.

BACKGROUND: Polyethylene wear and subsequent periprosthetic osteolysis remain a major concern of total hip arthroplasty (THA) failure in young, active patients with osteonecrosis of the femoral head (ONFH). The literature is lacking regarding the long-term performance of highly cross-linked polyethylene (HXLPE) in these patients. The purpose of this study is to evaluate long-term results for cementless THA using metal-on-HXLPE bearing couplings in patients younger than 50 years with ONFH. METHODS: We retrospectively evaluated the clinical and radiographic results of a consecutive series of 85 THAs (in 67 patients) performed with HXLPE liners (Durasul) in patients younger than 50 years who had ONFH. All procedures were performed at a single institution by a single surgeon using the same type of implants. The minimum duration of follow-up was 10 years (mean, 13.5 years; range, 10-17.3 years). Wear was measured using computer software. Osteolysis was evaluated with the use of radiography and computed tomography. RESULTS: The mean Harris hip score was 49.3 points (range, 26-68 points) before surgery, which improved to 93.6 points (range, 87-98 points) after surgery. Neither femoral nor acetabular components displayed mechanical loosening, and no components had been revised by the final follow-up evaluation. Radiographs and computed tomography scans did not demonstrate osteolysis. The mean liner wear was 0.037 mm/y (range, 0-0.099 mm/y). With the data available, univariate regression analysis did not demonstrate that age, sex, weight, activity level, underlying cause of osteonecrosis, liner thickness, or cup inclination had any influence on liner penetration. CONCLUSION: Although the long-term effects of HXLPE particles remain unknown, the implant survivorship rate and wear rate in our study are promising and support the continued use of metal-on-HXLPE bearing couplings in these high-risk patients because they do not produce any of the issues associated with hard-on-hard couplings. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: Although numerous studies have suggested that frozen shoulder (FS) is a self-limiting disease with most patients recovering within 2 years, its long-term outcome is still controversial. The aims of this study were to evaluate the clinical outcomes after conservative treatment for FS and to determine the predictors of its clinical outcome. METHODS: This study included 234 shoulders of 215 patients who received conservative treatment for FS. The mean follow-up period was 41.8 months (range 27-117 months). Initial evaluation included demographics, detailed medical history, and clinical assessments of shoulder status. Questionnaires, which included the Visual Analogue Scale (VAS) pain score, American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV) and satisfaction grading for the current shoulder status were assessed at the final follow-up. RESULTS: The mean VAS pain score, ASES score, and SSV significantly improved from 6.7, 37.0, and 40.1% at the time of initial evaluation to 1.5, 87.6, and 85.0% at the final follow-up evaluation (all p < 0.001). According to satisfaction grading, the shoulder status at the final follow-up was very satisfied in 101 shoulders (43.2%), satisfied in 68 (29.1%), fair in 37 (15.8%), unsatisfied in 20 (8.5%), and very unsatisfied in 8 (3.4%). Univariate analysis revealed that gender, diabetes, simultaneous bilateral involvement, overall bilateral involvement and duration of symptoms were associated with clinical outcomes at the final follow-up. Multivariate analysis revealed that duration of symptoms (p = 0.002) was an independent risk factor for unsuccessful outcome. CONCLUSIONS: At the mean follow-up period of 41.8 months, 72.3% of patients revealed subjective satisfaction for the current shoulder status. Duration of symptoms was an independent risk factor for poor prognosis.
