ABSTRACT

BACKGROUND: Previous studies have identified postoperative complications as being associated with readmission after lobectomy. However, these studies have not adequately accounted for the timing of complications or accounted for institutional effects. Our objectives were to examine readmission rates after lobectomy and identify factors associated with readmission.

METHODS: Patients aged >18 years undergoing lobectomy for lung cancer between 2015 and 2019 were identified from a statewide database. Patients with in-hospital mortality, missing data regarding discharge status, 30-day readmission status, and discharge location were excluded. Data regarding The Society of Thoracic Surgeons postoperative complications were abstracted by hospital data managers to determine the timing of occurrence (index admission vs readmission). Logistic mixed-model analysis, with hospitals as the random intercept to account for clustering data structure and assess hospital-specific effect on readmission, was performed.

RESULTS: The overall readmission rate was 6.9% (184 of 2686). The most common complication was air leak ≥5 days in 17.4% (467 of 2686). Variables significantly predictive of more readmission were predischarge postoperative complications and Zubrod score ≥1. Variables predictive of less readmission were increasing length of stay and having been operated on at institutions with higher cumulative volume or having postdischarge follow-up visit protocol ≤7 days from discharge. The C statistic for the final model was 0.80.

CONCLUSIONS: Patients who experience postoperative complications are at increased risk for readmission, whereas follow-up ≤7 days was predictive of less risk for readmission. Efforts at reducing readmissions should focus on decreasing postoperative complication rates, the timing of discharge for patients experiencing complications, as well as decreasing length of time between discharge and clinic follow-up.

ABSTRACT

OBJECTIVE: Hoarding disorder studies are primarily based on persons who seek treatment and demonstrate good insight. The aim of the present study is to evaluate whether there are differences between community and treatment-seeking samples of individuals with hoarding disorder (HD).

METHODS: Fourteen people with HD from the community and twenty treatment-seeking people with HD were assessed by a battery of instruments to evaluate HD features and other associated characteristics.

RESULTS: Compared to the treatment-seeking sample, the HD community sample was older, had poorer insight, and had a lower prevalence of comorbid obsessive-compulsive disorder (OCD). There were no differences in gender, education, presence of psychiatric comorbidities, quality of life, and hoarding behavior characteristics between the samples. The final logistic regression model with the Dimensional Obsessive-Compulsive Scale (DOCS) as the single predictor of treatment-seeking status was statistically significant, indicating that it was able to distinguish between the two samples. The model explained between 20.7% and 27.9% of the variance of subjects, and correctly classified 67.6% of cases.

CONCLUSIONS: Our results indicate that there appear to be few differences between the treatment-seeking and community samples of individuals with HD. The presence of comorbid OCD in treatment-seeking groups seems to be more frequent than in HD community samples.

ABSTRACT

BACKGROUND: Because of advances in medical treatment of heart failure, patients are living longer than in previous eras and may approach the need for advanced therapies, including heart transplantation, at older ages. This study assesses practices surrounding heart transplant in older adults (> 70 years) and examines short- and medium-term outcomes.

METHODS AND RESULTS: This study is a retrospective analysis using the United Network for Organ Sharing (UNOS) database from 2010 to 2021. The absolute number of older adults being transplanted is increasing. Older adults were more likely to have had a prior malignancy or ischemic cardiomyopathy and less likely to be on extra-corporeal membrane oxygenation or have a high UNOS status prior to transplant. Mortality at 1-year was higher for older adults (27.8% vs. 23.4%), but at 5 years there was no significant difference (22.3% vs. 19.4%.). Older adults were more likely to die of malignancy or infection. Adults under 70 were more likely to die of cardiovascular causes or graft failure. There was less rejection in older adults. Mortality has not changed for older adults transplanted before versus after the 2018 UNOS allocation change.

CONCLUSIONS: Carefully selected older adults may be considered for heart transplantation, given similar intermediate-term mortality.

ABSTRACT

OBJECTIVE: To provide insights into the learning curve of unilateral biportal endoscopic (UBE) spine surgery by synthesizing available evidence on critical points and associated clinical outcomes.

METHODS: A comprehensive literature search was conducted across multiple databases, yielding a pool of relevant studies. Inclusion criteria encompassed studies reporting on UBE learning curves and quantitative data related to clinical outcomes (operative time, hospital stay, and complications).

RESULTS: A total of five studies were included in the analysis, providing six datasets to elucidate the UBE learning curve. Three of the five studies analyzed learning curves using the Cumulative Sum method and identified cutoff points. One study plotted learning curves and determined cutoff points based on surgical time analysis, while the remaining one study (providing two datasets) plotted learning curves using the phased analysis method. The mean value of the cutoff point in terms of the number of cases required to reach proficiency in time to surgery was calculated at 37.5 cases, with a range spanning from 14 to 58 cases. Notably, there was a statistically significant difference in time to surgery between the late group and the early group, with the late group demonstrating a significantly reduced time to surgery (P < 0.0001). Additionally, the determined cutoff points exhibited significant variations when applied to patient outcome parameters, including postoperative hospitalization, postoperative drainage, and surgical complications (P < 0.05).

CONCLUSION: While the analysis indicates that UBE surgery’s learning curve is associated with surgical time, the limited focus on this metric and potential discrepancies in cutoff point determination highlight the need for a more comprehensive understanding.

ABSTRACT

INTRODUCTION: Infection with liver flukes (Opisthorchis viverrini) is partly attributed to their ability to thrive in sub-basin habitats, causing the intermediate host to remain within the watershed system throughout the year. It is crucial to conduct spatial monitoring of fluke infection at a small basin analysis scale as it helps in studying the spatial factors influencing these infections. The number of infected individuals was obtained from local authorities, converted into a percentage, and visually represented as raster data through a heat map. This approach generates continuous data with dependent variables.

METHODS: The independent set comprises nine variables, including both vector and raster data, that establish a connection between the location of an infected person and their village. Design spatial units optimized for geo-weighted modeling by utilizing a clustering and overlay approach, thereby facilitating the optimal prediction of alternative models for infection.

RESULTS AND DISCUSSION: The Model-3 demonstrated the strongest correlation between the variables X5 (stream) and X7 (ndmi), which are associated with the percentage of infected individuals. The statistical analysis showed t-statistics values of -2.045 and 0.784, with corresponding p-values of 0.016 and 0.085. The RMSE was determined to be 2.571%, and the AUC was 0.659, providing support for these findings. Several alternative models were tested, and a generalized mathematical model was developed to incorporate the independent variables. This new model improved the accuracy of the GWR model by 5.75% and increased the R ² value from 0.754 to 0.800. Additionally, spatial autocorrelation confirmed the difference in predictions between the modeled and actual infection values. This study demonstrates that when using GWR to create spatial models at the sub-basin level, it is possible to identify variables that are associated with liver fluke infection.

ABSTRACT

INTRODUCTION: Li-Fraumeni syndrome (LFS) is a hereditary cancer predisposition syndrome primarily caused by germline TP53 pathogenic/likely pathogenic (P/LP) variants. Soft tissue and bone sarcomas are among the most frequently occurring of the many LFS-associated cancer types. Cancer screening recommendations for LFS are centered around annual whole-body MRI (wbMRI), the interpretation of which can be challenging. This study aims to characterize sarcoma topography in LFS.

METHODS: Study subjects included individuals from clinically and genetically ascertained cohorts of germline TP53 variant-carriers, namely the National Cancer Institute’s LFS longitudinal cohort study (NCI-LFS), the NCI Genetic Epidemiology of Osteosarcoma (NCI-GEO) study, and the germline TP53 Database.

RESULTS: Data was aggregated for a total of 160 sarcomas that had detailed topography available. Abdominal sarcomas and extremity osteosarcomas were among the most frequent locations of sarcomas. Chi-squared analyses showed no statistical differences in sarcoma topography based on age (pediatric vs adult) or sex (male vs female). A case series of sarcomas from the NCI-LFS study highlights the diagnostic challenges due to topography-related imaging.

DISCUSSION: While LFS-related sarcomas frequently occur in expected locations such as the extremities, they also occur in less typical sites, leading to difficulties in discerning between differential diagnoses on wbMRI and imaging. Prospective collection of detailed cancer topography in individuals with LFS will further aid in recommendations for radiologic interpretation and personalized screening in individuals with LFS.

ABSTRACT

According to World Health Organization statistics, inappropriate medication has become an important factor affecting the safety of rational medication. In the gray area of medical insurance supervision, such as designated drugstores and medical institutions, there are lots of inappropriate medication phenomena regarding “big prescription for minor ailments.” A traditional clinical decision support system is mostly based on established rules to regulate inappropriate prescriptions, which are not suitable for clinical environments and require intelligent review. In this study, we model the complex relationships between patients, diseases, and drugs based on medical big data to promote appropriate medication use. More specifically, we first construct the medication knowledge graph based on the historical prescription big data of tertiary hospitals and medical text data. Second, based on the medication knowledge graph, we employ a Gaussian mixture model to group patient population representation as physiological features. For diagnostic features, we employ pre-training word vector Bidirectional Encoder Representations from Transformers to enhance the semantic representation between diagnoses. In addition, to reduce adverse drug interactions caused by drug combinations, we employ a graph convolution network to transform drug interaction information into drug interaction features. Finally, we employ the sequence generation model to learn the complex relationships between patients, diseases, and drugs and provide an appropriate medication evaluation for doctor prescriptions in small hospitals from two aspects: drug list and medication course of treatment. In this study, we utilize the MIMIC III dataset alongside data from a tertiary hospital in Fujian Province to validate our model. The results show that our method is more effective than other baseline methods in the accuracy of the medication regimen prediction of rational medication. In addition, it achieved high accuracy in the appropriate medication detection of prescription in small hospitals.

ABSTRACT

BACKGROUND: Randomized controlled trials (RCTs) are the gold standard for treatment efficacy, but foot and ankle RCTs are often small or inconsistent. The Fragility Index (FI) evaluates the stability of significant findings. This study assessed the fragility of RCT outcomes for Achilles tendon pathology (ATP) interventions.

METHODS: This systematic review queried PubMed up to May 14, 2024, for RCTs on ATP interventions. RCTs with significant binary outcomes were included. Two reviewers assessed eligibility, extracted data, calculated FIs, and evaluated risk of bias. Frequency-weighted means were used for narrative synthesis.

RESULTS: Eleven RCTs with 4506 patients (mean cohort size: 409.64 ± 160.54) and a mean age of 36.97 ± 13.51 years (n = 4356; 96.67%) were included, covering 24 binary outcomes. The median FI across all outcomes was 3 (interquartile range 1-4; mean 3.92), indicating that changing the outcome of just a few patients could shift a study’s results from statistically significant to nonsignificant. Trials having an FI ≤3 comprised 58.33%. Three outcomes (12.5%) had an FI of zero after recalculating P values using the two-sided Fisher exact test. Half of the outcomes were robust. No RCT reported FIs or adjusted significance for multiple testing. Most studies (81.82%) performed 2 or more statistical tests, with an average of 30.81 ± 41.28 P values reported per study. The overall risk of bias was low in 1 study (9.09%) and moderate in 7 (63.64%). Most studies had low risk of bias in randomization (72.73%) and missing outcome data (90.91%).

CONCLUSION: The FI assesses the fragility of statistically significant binary results, revealing that many ATP RCTs have fragile outcomes due to small sample sizes. A median FI of 3 means that changing the outcome of 3 patients could shift a study’s results from statistically significant to nonsignificant.

ABSTRACT

OBJECTIVE: This network meta-analysis aims to explore the efficacy and safety of neuroprotective agents in patients with ischemic stroke and attempts to identify which drug is the most effective in improving outcomes for patients with acute ischemic stroke (AIS) through a ranking method.

METHODS: We comprehensively searched the PubMed, Medline, Embase, Web of Science, and Cochrane library databases from their establishment to 30 June 2024. Data were extracted from the studies identified, and their quality was assessed using the Cochrane risk-of-bias tool or the Newcastle-Ottawa Scale (NOS). The outcome measures were for a favorable prognosis, based on the modified Rankin Scale score (mRS) or National Institutes of Health Stroker Scale (NIHSS) score, mortality, and adverse effect with different drug regimens. We utilized Stata version 16.0 and Review Manager (RevMan) version 5.3.0 for statistical analysis.

RESULTS: A total of 35 studies were included: 25 randomized control trials, eight retrospective studies, and two prospective studies. The total sample size was 18,423 cases and included nine interventions: citicoline, edaravone (EDV), edaravone dexborneol, cinepazide maleate, cerebrolysin, minocycline, ginkgolide, ginkgo diterpene lactone meglumine (GDLM), and conventional (CON) treatment. Our analysis revealed that, except for edaravone dexborneol, the ginkgolide, EDV, cinepazide maleate, citicoline, cerebrolysin, minocycline, and GDLM treatment schemes reduced the mortality of patients with AIS compared with CON. Each drug regimen significantly improved the neural function of these patients compared with CON, which from highest to lowest was citicoline + vinpocetine, GDLM, citicoline, edaravone dexborneol, cinepazide maleate, ginkgolide, EDV, and CON. Moreover, we also found that, except for citicoline, the ginkgolide, EDV, edaravone dexborneol, GDLM, and cinepazide maleate treatment schemes had a high total treatment effective rate in these patients, the order from highest to lowest being ginkgolide, EDV, edaravone dexborneol, GDLM, cinepazide maleate, CON, and citicoline. In terms of the ineffective rate, we found that, compared with CON, the edaravone dexborneol, EDV, citicoline, GDLM, ginkgolide, and cinepazide maleate treatment schemes all had a lower ineffective rate. Finally, our analysis revealed that, except for cinepazide maleate and ginkgolide, the EDV, minocycline, edaravone dexborneol, GDLM, citicoline, and cerebrolysin schemes all had a higher rate of adverse effect on patients compared to CON. Based on the impact of the adverse effect with different surgical interventions, we further analyzed the effect of these drug treatments by the total treatment effective rate combined with adverse effect, revealing that EDV, ginkgolide, and edaravone dexborneol were the safest and most effective treatments.

CONCLUSION: In patients with AIS, ginkgolide, EDV, cinepazide maleate, citicoline, cerebrolysin, minocycline, and GDLM were associated with a reduction in mortality rate. Moreover, ginkgolide, EDV, edaravone dexborneol, and GDLM treatment schemes revealed not only a high total treatment effective rate but also a low rate of treatment inefficacy. When considering the combination of the total treatment effective rate with adverse effect, EDV, ginkgolide, and edaravone dexborneol were revealed as the safest and most effective.

ABSTRACT

BACKGROUND: This study analyzed the FDA’s Adverse Event Reporting System (FAERS) data to investigate the correlation between oral bisphosphonates (BPs) and oesophageal adverse events (AEs).

METHODS: We systematically extracted data on adverse reactions to oral alendronate, risedronate, and ibandronate from the FAERS database, covering the period from the 2004 Q1 to the 2023 Q4. The role_code of AEs mainly includes primary suspect (PS), secondary suspect (SS), concomitant (C), and interaction (I). This study targeted reports with a role_code of “PS.” According to the FDA deduplication rule, the latest FDA_DT is selected when the CASEID is the same, and the higher PRIMARYID is selected when the CASEID and FDA_DT are the same. Our analysis leveraged four statistical methods, including the reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and the multi-item gamma Poisson shrinker (MGPS), to assess the relationship between oral bisphosphonates and oesophageal AEs. The Kaplan-Meier method was utilized to evaluate the cumulative incidence of oesophageal toxicity, while the log-rank test examined the temporal onset profiles of these toxicities. Additionally, the Pearson chi-squared test was employed to identify any significant differences in mortality and hospitalization rates associated with the oesophageal AEs caused by these medications.

RESULTS: The FAERS database had 41,590 AE reports for oral BPs, with 3,497 (8.41%) related to oesophageal AEs. Our findings indicate that oral BPs are disproportionately associated with an increased incidence of gastrointestinal system AEs at the system organ class (SOC) level. The adverse events identified at the preferred terms (PTs) level encompassed conditions such as gastroesophageal reflux disease, oesophagitis, and oesophageal pain. A significant divergence in the cumulative incidence of oesophageal AEs was observed among patients treated with the three different oral bisphosphonates, as confirmed by the log-rank test (p < 0.0001). Hospitalization rates varied significantly among patients receiving different BPs (p < 0.05), but no significant difference in mortality rates was found.

CONCLUSION: The study establishes a significant link between oral BPs and oesophageal toxicity, highlighting the need for further research into the mechanisms of BP-induced oesophageal toxicity and potential preventive measures.
