[PMID: 38762418 DOI: 10.1016/j.cjtee.2024.04.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 03/18/2024] [Accepted: 04/09/2024] [Indexed: 05/20/2024] Open
Abstract
PURPOSE Intertrochanteric fracture (ITF) classification is crucial for surgical decision-making. However, orthopedic trauma surgeons have shown lower accuracy in ITF classification than expected. The objective of this study was to utilize an artificial intelligence (AI) method to improve the accuracy of ITF classification. METHODS We trained a network called YOLOX-SwinT, which is based on the You Only Look Once X (YOLOX) object detection network with Swin Transformer (SwinT) as the backbone architecture, using 762 radiographic ITF examinations as the training set. Subsequently, we recruited 5 senior orthopedic trauma surgeons (SOTS) and 5 junior orthopedic trauma surgeons (JOTS) to classify the 85 original images in the test set, as well as the images with the prediction results of the network model in sequence. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) 20.0 (IBM Corp., Armonk, NY, USA) to compare the differences among the SOTS, JOTS, SOTS + AI, JOTS + AI, SOTS + JOTS, and SOTS + JOTS + AI groups. All images were classified according to the AO/OTA 2018 classification system by 2 experienced trauma surgeons and verified by another expert in this field. Based on the actual clinical needs, after discussion, we integrated 8 subgroups into 5 new subgroups, and the dataset was divided into training, validation, and test sets by the ratio of 8:1:1. RESULTS The mean average precision at the intersection over union (IoU) of 0.5 (mAP50) for subgroup detection reached 90.29%. The classification accuracy values of SOTS, JOTS, SOTS + AI, and JOTS + AI groups were 56.24% ± 4.02%, 35.29% ± 18.07%, 79.53% ± 7.14%, and 71.53% ± 5.22%, respectively. The paired t-test results showed that the difference between the SOTS and SOTS + AI groups was statistically significant, as well as the difference between the JOTS and JOTS + AI groups, and the SOTS + JOTS and SOTS + JOTS + AI groups. Moreover, the difference between the SOTS + JOTS and SOTS + JOTS + AI groups in each subgroup was statistically significant, with all p < 0.05. The independent samples t-test results showed that the difference between the SOTS and JOTS groups was statistically significant, while the difference between the SOTS + AI and JOTS + AI groups was not statistically significant. With the assistance of AI, the subgroup classification accuracy of both SOTS and JOTS was significantly improved, and JOTS achieved the same level as SOTS. CONCLUSION In conclusion, the YOLOX-SwinT network algorithm enhances the accuracy of AO/OTA subgroups classification of ITF by orthopedic trauma surgeons.

Burke CA, Nitti VW, Stothers L. Melatonin and melatonin receptor agonists in the treatment of nocturia: A systematic review. Neurourol Urodyn 2024; 43:826-839. [PMID: 38456646 DOI: 10.1002/nau.25443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 02/19/2024] [Accepted: 02/28/2024] [Indexed: 03/09/2024]
Abstract
AIM Causes of nocturia may extend beyond primary bladder pathology and it has been commonly associated as a side effect of sleep disorders. This has led to the study of melatonin and melatonin receptor agonists as a primary treatment for nocturia hypothesized to be secondary to sleep disorders. We aim to systematically review the efficacy and reported safety of melatonin and melatonin receptor agonists in the treatment of nocturia. METHODS A search strategy of EMBASE and Pubmed/Medline databases was utilized to identify eligible studies. Two thousand and twenty-eight unique references were identified in concordance with the Preferred Reporting Items of Systematic Reviews and Meta-Analyses guidelines for systematic reviews, of which nine papers met the inclusion criteria. The Cochrane Collaboration risk of bias criteria in the open label and nonplacebo studies was used to assess bias. RESULTS The nine studies identified included 3 randomized double-blinded placebo-controlled trials, 2 randomized non-placebo trial, and 4 prospective open-label trials. Three utilized the melatonin-receptor agonist ramelteon (8 mg) and six utilized melatonin (four 2 mg extended release, two 2 mg normal release). Nocturia improved in 8 studies varying from moderate to low efficacy related to reduction in nocturia episodes. Five studies evaluated sleep parameters finding improvement in both nocturia and sleep quality. Male subjects represented 76.8% of 371 total subjects in prospective and randomized trials. Ramelteon and melatonin were both reported as well tolerated during nocturia treatment. A meta-analysis was not able to be performed due to the heterogeneity of bladder diagnoses. CONCLUSIONS At this time, there is insufficient evidence to routinely recommend melatonin as an effective treatment for nocturia given the limitations of current clinical studies. Randomized placebo-controlled trials and prospective open label studies in non-neurogenic populations report a trend towards nocturia improvement with good tolerability and rare side effects. Therefore, further larger scale randomized trials with focused urologic diagnoses in well-characterized patient populations are warranted.

Abstract
BACKGROUND Mortality rates following emergency spine fracture surgery are high, especially in the elderly. However, how the postoperative mortality rate following spine fractures compares to other geriatric fractures such as hip fractures remains unclear. Therefore, this retrospective cohort study aimed to compare 30-day mortality rates and risk factors between emergency spine fracture versus hip fracture surgery in the elderly. METHODS The National Surgical Quality Improvement Program (NSQIP) database was queried between 2011 and 2021 for emergency spine fractures and hip fractures in the elderly. Univariate analyses evaluated demographic data, perioperative factors, comorbidities, and 30-day mortality rates as the primary outcomes. A multivariable regression model was then constructed to control for significant baseline and demographic differences and evaluate independent predictors of mortality. RESULTS A total of 18,287 emergency hip fractures and 192 emergency spine fractures were included in our study. Univariate analysis demonstrated significant differences in female sex, body mass index (BMI), operation time, length of hospital stays, disseminated cancer, and functional dependence between spine and hip fractures. Thirty-day mortality rates were significantly higher in spine versus hip fractures (9.4% vs. 5%). Multivariate regression analysis demonstrated emergent spine fracture surgery, disseminated cancer, functional dependence, and length of stay as independent predictors of mortality in our cohort. Female sex, BMI, and operation time were protective factors for mortality in our cohort. CONCLUSIONS Emergency spine fractures in the elderly represent an independent predictor for 30-day postoperative mortality compared to emergency hip fractures. Disseminated cancer, functional dependence, and length of stay were independent predictors of mortality while female sex, BMI, and operation time were protective factors. These data demonstrate the severity of injury and high rates of mortality that clinicians can use to counsel patients and their families.

Abstract
This study aimed to test a model of factors associated with resilience and physical activity post-hip fracture and compare model fit between men and women. We used data from the seventh Baltimore Hip Study that included 339 participants. Model testing indicated that health status (men: β = .237, p = .002; women: β = .265, p = <.001), depression (men: β = -.245, p = .001; women: β = -.241, p = <.001), and optimism (men: β = .320, p = <.001; women: β = .282, p = <.001) were associated with resilience in men and women, but resilience was only associated with physical activity in men (β = .203, p = .038) and not in women. Social interaction was related to physical activity only among women (β = .206, p = .044). This study provides support for the relationship between resilience and physical activity at least among men.

Abstract
Background and Objectives: The epidemiological pattern of the hip fracture burden attributable to falls in Central European countries is still insufficiently known. The aim of this study was to assess the regional and national trends of hip fractures due to falls in Central Europe from 1990 to 2019. Materials and Methods: Using the Global Burden of Disease (GBD) 2019 study, this descriptive epidemiological study presents trends in incidence of and Years Lived with Disability (YLDs) from hip fractures due to falls in the region of Central Europe. All estimates (age- and sex-specific rates, and age-standardized rates) were expressed per 100,000. A joinpoint regression analysis was used to assess trends: the average annual percent change (AAPC) with a corresponding 95% confidence interval (95% CI) was calculated. Results: Among all new cases of hip fracture in the population as a whole in Central Europe in 2019, 3.9% in males and 7.0% in females were attributable to falls, while the share of hip fractures due to falls in the population aged 70 and over was 16.9% in males and 20.0% in females. About 400,000 new cases of hip fracture due to falls occurred in the Central European region in 2019 (220,000 among males and 160,000 among females), resulting in 55,000 YLDs (32,000 in females and 22,000 in males). About one-third of all new cases (59,326 in males and 72,790 in females) and YLDs (8585 in males, and 10,622 in females) of hip fractures due to falls were recorded in Poland. From 1990 to 2019, the age-standardized incidence rates of hip fracture due to falls showed a decreasing tendency in females (AAPC = -1.1%), and an increasing tendency in males (AAPC = 0.1%). Both in males and females, YLDs rates of hip fracture due to falls in the Central European region decreased (AAPC = -1.6% and AAPC = -2.4%, respectively). Conclusions: Hip fracture due to falls represents an important health issue in the Central European region, although incidences and YLDs declined in the most recent decades. However, further efforts to reduce the burden of hip fractures attributed to falls are needed.

Abstract
BACKGROUND Hip fracture accounts for a considerable burden of disease in older adults, yet there is a paucity of data pertaining to longer-term outcomes in the Irish Hip Fracture population. Understanding the factors that influence longer-term survival would allow care pathways to be refined to optimise patient outcomes. In Ireland, there is no linkage to death registration at a national or regional level, nor are longer-term outcomes captured by the Irish Hip Fracture Database. This study aimed to quantify 1-year mortality in an Irish hip fracture cohort and identify factors that influence survival at 1 year. METHODS A retrospective review of hip fracture cases in an Irish urban trauma centre over a 5-year period was conducted. Mortality status was obtained via the Inpatient Management System and correlated with the Irish Death Events Register. A range of routinely collected patient and care process variables were analysed using logistic regression. RESULTS A total of 833 patients were included. Within 1 year of sustaining a hip fracture, 20.5% (171/833) had died. On multivariate analysis, female gender (OR 0.36, p < 0.001, 95% CI 0.23-0.57), independent mobility pre-fracture (OR 0.24, p < 0.001, 95% CI 0.14-0.41) and early mobilisation on the day of or after surgery (OR 0.48, p < 0.001, 95% CI 0.30-0.77) reduced the likelihood of dying within 1 year (AUC 0.78). CONCLUSION Of the variables examined, early postoperative mobilisation was the only modifiable factor identified that conferred a longer-term survival benefit. This underscores the importance of adhering to international best practice standards for early postoperative mobilisation.

Concomitant fractures in patients with proximal femoral fractures lead to a prolonged hospital stay but not to increased complication rates or in-house mortality if treated surgically: a matched pair analysis. Aging Clin Exp Res 2023; 35:607-614. [PMID: 36694062 PMCID: PMC10014667 DOI: 10.1007/s40520-023-02348-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 01/10/2023] [Indexed: 01/26/2023]
Abstract
BACKGROUND Impact of concomitant fractures on patients sustaining a proximal femur fracture remains unclear. Rising numbers and patient need for rehab is an important issue. The objective of our study was to investigate the impact of concomitant fractures, including all types of fractures, when treated operatively, for proximal femur fractures on the length of hospital stay, in-house mortality and complication rate. METHODS Observational retrospective cohort single-center study including 85 of 1933 patients (4.4%) with a mean age of 80.5 years, who were operatively treated for a proximal femoral and a concomitant fracture between January 2016 and June 2020. A matched pair analysis based on age, sex, fracture type and anticoagulants was performed. Patient data, length of hospital stay, complications and mortality were evaluated. RESULTS The most common fractures were osteoporosis-associated fractures of the distal forearm (n = 34) and the proximal humerus (n = 36). The group of concomitant fractures showed a higher CCI than the control group (5.87 vs. 5.7 points; p < 0.67). Patients with a concurrent fracture had a longer hospital stay than patients with an isolated hip fracture (15.68 vs. 13.72 days; p < 0.056). Complications occurred more often in the group treated only for the hip fracture (11.8%, N = 20), whilst only 7.1% of complications were recorded for concomitant fractures (p < 0.084). The in-house mortality rate was 2.4% and there was no difference between patients with or without a concomitant fracture. CONCLUSIONS A concomitant fracture to a hip fracture increases the length of hospital stay significantly but does not increase the complication rate or the in-house mortality. This might be due to the early mobilization, which is possible after early operative treatment of both fractures.
