Patient-Level Factors, Outcomes, and Costs Associated with Facility Transfer following Total Knee Arthroplasty: A Retrospective Database Study

Patient disposition following total knee arthroplasty (TKA) has major implications for patient outcomes and costs. Current studies are limited in sample size and dates of data collection. We evaluated patient factors, outcomes, and costs associated with disposition to a facility following TKA. This was a retrospective cohort study including 1,906,670 patients undergoing TKA from a national wide database, from the years 2016 to 2020. Of these, 25,485 (1.34%) patients were transferred to a facility for rehabilitation. Demographic data, hospital-related outcomes, and postoperative complications were collected. Multivariate regression was performed to assess outcomes associated with facility transfer for rehabilitation. Patients were more likely to be transferred if they were women (Odds Ratio (OR) = 1.10; P < 0.001), greater than 80 years old (OR = 2.25; P < 0.001), had an increased Elixhauser comorbidity index (OR = 1.38; P < 0.001), or were in the lowest income quartile (OR = 1.38; P < 0.001). Transferred patients were more likely to experience medical (OR = 1.92; P < 0.001) and surgical complications (OR = 2.74; P < 0.001), including vascular complications (OR = 2.07; P < 0.001), neurologic complications (OR = 5.72; P < 0.001), and dislocation (OR = 2.01; P < 0.001). They also had greater hospital lengths of stay (OR = 5.27; P < 0.001) and hospital charges (OR = 1.88; P < 0.001); however, they were less likely to undergo reoperation within 30 days (OR = 0.61; P = 0.002). Elderly, lower-income patients who had more comorbidities are more likely to be transferred to a facility following TKA. While there are associated increased costs, complications, and hospital lengths of stay, there are lower rates of reoperation for those who transferred to a facility after TKA.

Incidence of Uveitis Following Initiation of Prostaglandin Analogs Versus Other Glaucoma Medications: A Study from the SOURCE Repository.

To evaluate the risk of incidence rates of uveitis among patients starting topical glaucoma therapy. Retrospective database study utilizing the Sight Outcomes Research Collaborative (SOURCE) Ophthalmology Data Repository. Adult glaucoma patients who were recently started on topical glaucoma therapy. Using data from 10 health systems contributing data to the SOURCE data repository, we identified all adult glaucoma patients who had been newly started on a topical glaucoma medication (prostaglandin analogues (PGAs), beta-blockers (BBs), alpha agonists (AAs), and carbonic anhydrase inhibitors (CAIs)). Patients with pre-existing documentation of uveitis were excluded. Incidence of uveitis within 3 months of initiating therapy with different topical glaucoma medications. We included 67,517 patients who were newly prescribed a topical glaucoma medication. The mean age of the patients was 67.3±13.2 years and ∼59% were females. A total of 567 patients (0.87%) developed uveitis within 3 months of initiating the therapy. The incidence of uveitis was 0.32%, 1.95%, 1.63%, and 1.68% for users of PGAs, BBs, AAs, and CAIs, respectively. After adjusting for sociodemographic factors, individuals using topical BBs, AAs, and CAIs had significantly higher odds of developing uveitis versus those using PGAs (P<0.001 for all comparisons). The use of PGAs was not associated with higher odds of developing uveitis compared to other classes of topical glaucoma medications.

A Systematic Review of Reporting and Handling of Missing Data in Observational Studies Using the UNOS Database

BackgroundMissing data can undermine a registry’s ability to draw valid inferences by decreasing study power and introducing bias. We evaluated how missing data are reported and addressed in observational studies of adult heart transplantation (HT) recipients using the United Network for Organ Sharing (UNOS) database. MethodsWe conducted a systematic literature search of Medline from January 1st, 2018 through August 22nd, 2023 and included studies that used the UNOS database to evaluate adult (≥18 years) de novo HT recipients. We collected details on the study population, timeframe, primary endpoint, use of missing data, and whether and what methods were used to handle missing data. Approaches were classified as variable selection, complete case analysis (CCA), missing indicator method, single imputation, or multiple imputation. Results229 studies were included from 2018-2023. 67 (29.3%) studies limited their cohorts to those without missing data for the outcome or key variables and 93 (40.6%) reported missing data in their final cohort. 78 (34.1%) studies reported how they handled missing data in their statistical modeling. Of these, CCA was most used (n=41, 52.6%) followed by multiple imputation (n=22, 28.2%), and other methods (n=15, 19.2%) including a combination of missing indicator method (for binary variables) and single imputation. Thirty-one (13.5%) studies reported removing covariates from their analysis because of missing data. Only four (5.1%) studies reported sensitivity analysis to evaluate different missing data approaches. ConclusionsMerely a third of the identified UNOS database studies reported how they handled missing data in their analysis, with strategies varying. Although no singular approach to handling missing data exists, methods are available that can improve upon the most used approaches by, for example, reducing bias and increasing statistical power. Though these improvements are contingent on the missing data mechanism and the goals of the analysis. Future best practices should include explicit reporting of missingness, detailed methods, and sensitivity checks to maximize the credibility of UNOS database analyses.

The Burden of Seasonal Influenza and Its Potential Complications Among Older Japanese Adults: A Real-World Database Study.

Seasonal influenza may lead to severe complications, including respiratory and cardiovascular disease, that result in considerable healthcare resource utilization (HCRU) and mortality, particularly in older individuals. This real-world study assessed the burden of influenza and its potential complications in older Japanese adults. This retrospective claims database analysis (April 2015 to June 2019) included insured individuals aged ≥ 60 years at the start of four consecutive influenza seasons in Japan (October 1 to April 30). The primary endpoint was the incidence of influenza-related emergency room (ER) and outpatient visits, the incidence of hospitalizations, the probability of 30-day inpatient mortality, and 60-day medical costs of influenza or its potential complications. Of 8,974,708 individuals (43.2% male, mean ± standard deviation age 73.8 ± 8.9 years), 370,430 (4.13%) were diagnosed with influenza. Overall, 17.18 (95% confidence interval [CI] 16.32-18.04) and 3893.53 (3880.87-3906.19) per 100,000 individuals had influenza-related ER and outpatient visits, respectively, and 181.50 (178.71-184.28) per 100,000 individuals were hospitalized for influenza. The incidence of influenza-related ER visits and hospitalizations for influenza or potential complications and the probability of 30-day inpatient mortality increased with age. Seasonal influenza and its potential complications represent a substantial burden that increases with age in Japanese individuals.

Association of Serum Blood Urea Nitrogen to Albumin Ratio with in-Hospital Mortality in Patients with Acute Ischemic Stroke: A Retrospective Cohort Study of the eICU Database

Albumin (ALB) and blood urea nitrogen (BUN) are both associated with the prognosis of acute ischemic stroke (AIS). A recent prognostic marker, the BUN/ALB ratio (BAR), has been suggested as a simple and sensitive method to predict certain acute diseases. To determine the predictive value of BAR in relation to the risk of in-hospital mortality among AIS patients. Retrospective cohort study. Cox regression analysis was employed to assess the relationship between in-hospital mortality and BAR, with hazard ratios (HRs) and 95% confidence intervals. Subgroup analysis of acute pulmonary embolism, acute myocardial infarction (AMI), thrombolysis, thrombectomy, and septic shock was performed to further examine this relationship. The predictive value of BAR and BAR multivariate models for in-hospital mortality was evaluated and compared to BUN, ALB, the Acute Physiology and Chronic Health Evaluation IV (APACHE IV) score, and the Sequential Organ Failure Assessment Score (SOFA). Among the 1,635 eligible patients, 226 (13.81%) died during hospitalization. An elevated serum BAR level was associated with an increased in-hospital mortality risk (HR: 1.3) after covariates were adjusted. Additionally, this positive association was observed in patients without AP, AMI, thrombolysis, history of thrombectomy, or septic shock (all; p < 0.05). The efficacy of the BAR multivariate model in predicting in-hospital mortality among AIS patients was superior to that of both APACHE IV and SOFA, with an area under the curve of 0.87. Serum BAR exhibits the potential to identify AIS patients with high mortality risk, which may contribute to enhanced disease surveillance and risk stratification.

Comparison of RVU Reimbursement in Anterior or Posterior Approach for Single- and Multilevel Cervical Spinal Fusion.

Retrospective database study. This study aims to quantify and compare mean work RVUs (wRVUs), mean operative time (OpTime), and wRVUs/min in single- and multilevel anterior and posterior cervical spine fusions performed between 2011 and 2020. Prior research has demonstrated inconsistencies in technical skill, operative time, and surgical difficulty with reimbursement in various orthopedic subspecialties. Although trends investigating physician effort and reimbursement have been investigated in lumbar spine surgery, less research has examined these relationships with respect to cervical spine procedures. The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) was queried for Current Procedural Terminology (CPT) codes reflecting anterior cervical discectomy and fusion (ACDF), posterior cervical decompression and fusion (PCDF), and the number of levels involved. The cohort was stratified into 10 groups: single-level, 2-level, 3-level, 4-level, 5+ level anterior or posterior cervical fusions. Mean operative times, mean wRVUs, and wRVU/min were calculated and compared by Student t test. A total of 100,997 patients met inclusion criteria in this study, of which 79,141 (78.36%) underwent ACDF, whereas 21,836 (21.62%) underwent PCDF. One- and 2-level fusions were most common in both ACDF and PCDF. In 1-, 3-, 4-, and 5+ level fusion, the anterior approach demonstrated significantly lower mean wRVU (P<0.001). In 1-, 2-, and 3-level fusions, the anterior approach had significantly lower operation times (P<0.001). The anterior approach demonstrated significantly higher wRVU/min in 1- and 2- levels (P<0.001) but lower wRVU/min in 3- and 4-level fusions (P<0.001). Clear discrepancies exist between surgical approach and levels of fusion in cervical spine procedures incongruous with markers of surgical difficulty, physician effort, or expertise required. These specific results suggest that the complexity of multi-level anterior cervical fusions are not effectively accounted for by existing RVU measures.

Outcomes of Cataract Surgery Complicated With Zonular Dialysis: A Multicenter Comparative Study

Purpose To compare the visual outcomes, rate of cystoid macular edema (CME), and additional associated complications in eyes that exhibited zonular dialysis (ZD) during phacoemulsification to a reference group of uneventful phacoemulsification eyes. Methods A retrospective multicenter comparative database study. We pooled data from 8 United Kingdom sites between 2003 and 2015. The main outcome measures were the mean postoperative visual acuity (VA) at 12–24 weeks and the rates of CME and additional associated complications. Results We included 1074 eyes in the ZD group and 112,479 in the reference group. Logistic regression analysis showed that pseudoexfoliation was the strongest associated factor of ZD (OR: 6.1), followed by previous glaucoma surgery (OR: 4.4). Mean logMAR preoperative VA was 0.8 ± 0.6 in the ZD group vs. 0.6 ± 0.5 in the reference group (p < 0.001). Mean postoperative VA was worse in the ZD group (p < 0.001); 0.4 ± 0.6 vs. 0.2 ± 0.3 and 0.5 ± 0.6 vs. 0.2 ± 0.3 at 4–12 weeks and 12–24 weeks, respectively. At 12–24 weeks, the proportions of eyes that gained ≥0.3 logMAR units were 50% in the ZD group vs. 62% in the reference group (p < 0.001). In the ZD group, the most common intraoperative complication was vitreous loss (34.3%), followed by posterior capsular rupture (PCR) (11.1%). Postoperative CME occurred in 2.3% vs. 1.4% (p = 0.01), and 9.3% of eyes required surgery for correction of aphakia, intraocular lens decentration, or dropped lens figments removal. Conclusions The occurrence of ZD was associated with worse postoperative vision, an increased rate of vitreous loss and PCR, and a higher risk of CME.

A cross-sectional study of recent patterns of psychotropic medication use in children and adolescents in Ireland.

There has been a global rise in prescribing of psychotropic medications. Variations in patterns of use, according to age, gender and drug class type, have also been reported. This study aimed to analyse patterns of psychotropic medication use in Ireland according to age group, gender and drug class type, to determine if variations exist, and identify specific nuances to be addressed in future research. A retrospective, repeated, cross-sectional study of the Irish pharmacy claims database (community setting dispensing data) was conducted. Yearly prevalence of children/adolescents receiving dispensed psychotropic medications was analysed from January 2017 to December 2021, across years, age groups (5-15, 5-11 and 12-15 years), gender and drug class type. All available data were used. Yearly prevalence was the mean number of patients receiving medication per month per 1000 eligible population during a given year. Negative binomial regression was used to examine association of year, age group and gender on prevalence. In the 12-15 years group, prevalence for all selected psychotropic medications in 2021 in males was almost twice that in females (19.92/1000 vs 10.62/1000). In the 5-11 years group, prevalence was three times higher in males than females (7.56/1000 vs 2.49/1000). Overall, there was a higher rate of increase in females and higher usage in older children. This study found variations in psychotropic medication use in children/adolescents, depending on age, gender and drug class type. Further research is needed to determine whether variations have resulted in treatment disparities for certain cohorts.

Incidence and risk factors of pain following breast cancer surgery: a retrospective national inpatient sample database study

BackgroundPostoperative pain (PP) is a dynamic process that reflects the complex interplay between symptoms, treatment, and patient experiences, and its intensity is reportedly primarily related to the severity of surgical trauma. However, no large-scale national database-based study has hitherto been conducted to assess the occurrence and features related to PP following breast cancer (BC) surgery.MethodsIn this retrospective analysis, we screened BC surgery cases between 2015 and 2019 within the National Inpatient Sample (NIS) Database, utilizing the International Classification of Diseases (ICD) 10th edition clinical modification codes. The researchers identified patients who developed PP and compared them to those who did not. Factors associated with PP were then screened: patient demographics (age and race), hospital characteristics (type of insurance, bed size, teaching status, type of admission, location, and hospital area), length of stay (LOS), total cost during hospitalization, inpatient mortality, comorbidities, and perioperative complications. Data were analyzed using descriptive statistics. Multivariate logistic regression analysis was used to determine the independent risk factors for postoperative pain in BC surgery.Results39,870 BC surgery cases were identified over a five-year period from 2015 to 2019. The overall occurrence of PP following breast cancer surgery was 6.15% (2,387 cases), with a slight upward trend every year. Significant racial disparities were observed, Whites associated with a higher incidence of PP (P < 0.001). In addition, the incidence of elective admission was 11.96% lower (67.491% vs. 79.451%) than that of patients without PP following breast cancer surgery (P < 0.001). Besides, PP was related to prolonged hospitalization duration (3 vs. 2 days; P < 0.001), and higher total cost ($68,283 vs. $60,036; P < 0.001). Multivariate logistic regression identified breast cancer surgery-independent risk factors for PP, including younger age, non-elective hospital admission, rural hospitals, depression, drug abuse, metastatic cancer, psychoses, weight loss, and chronic pulmonary disease. In addition, postoperative pain for BC was associated with urinary retention, gastrointestinal complications, continuous invasive ventilation, deep vein thrombosis, urinary tract infection, blood transfusion, arrhythmia, and chest pain.ConclusionDespite the low incidence of postoperative pain in BC surgery cases, it is essential to investigate factors predisposing to PP to allow optimal care management and improve the outcomes of this patient population.

Addressing bias due to measurement error of an outcome with unknown sensitivity in database epidemiological studies.

In epidemiological database studies, the occurrence of an event is measured with error through an indicator whose specificity is often maximised, at the expense of sensitivity. However, if the indicator has low sensitivity, measures of occurrence are underestimated. In association studies, risk difference is biased, and risk ratio may be biased as well, in either direction, if the sensitivity is differential across exposure groups. In this work, we show that if an auxiliary screening indicator can be defined to complement the main indicator, estimates of the positive predictive value of both indicators provide tools to estimate the sensitivity of the primary indicator, or a lower bound thereof. This mitigates bias in estimating the number of cases, prevalence, cumulative incidence, rate (particularly when the event is rare), and in association studies, risk ratio and risk difference. They also allow testing for non-differential sensitivity. While direct estimation of sensitivity is often infeasible, this novel methodology improves evidence based on data obtained from re-use of existing databases, which may prove critical for regulatory and public health decisions.

Cardiovascular Mortality Risk among Patients with Liver Cancer: A SEER Database Study.

Data sourced from the Surveillance, Epidemiology, and End Results (SEER) database encompassing liver cancer diagnoses from 2000 to 2017 were utilized. The standardized mortality rate (SMR) was computed using general population reference data, and multivariate competing risk models were employed for analysis. Analysis of 70,733 liver cancer patient records revealed 1,954 instances of CVM. The overall CVM SMR for liver cancer patients was 12.01 (95% CI: 11.48-12.55). Various demographic and clinical factors, including sex, race, age, year of diagnosis, pathological type, general stage, treatment modalities, and matrimonial status, emerged as liver cancer pa-tients` independent predictors of CVM. Liver cancer patients have a notably heightened susceptibility to cardiovascular mortality (CVM) in contrast to the general populace. It is imperative to promptly recognize high-risk subcategories and execute tailored cardiovascular interventions as crucial measures to bolster survival rates within this cohort of patients.

Effectiveness of an Impella versus intra-aortic balloon pump in patients who received extracorporeal membrane oxygenation: a nationwide inpatient database study

Abstract Background/Introduction Previous studies have suggested that left ventricular (LV) unloading with an intra-aortic balloon pump (IABP) or percutaneous ventricular assist device (Impella) in combination with extracorporeal membrane oxygenation (ECMO) is associated with lower mortality; however, it is unclear which is better. Purpose This study aimed to evaluate the effectiveness of LV unloading with an Impella versus IABP on in-hospital mortality and other clinical outcomes. Methods Using the Japanese Diagnosis Procedure Combination database from September 28, 2016, to March 31, 2022, we identified inpatients who received an Impella or IABP in combination with ECMO (ECPella or ECMO+IABP group, respectively). The primary outcome was in-hospital mortality and the secondary outcomes were the length of hospital stay, length of ECMO, total hospitalization cost, and complications including major bleeding, an ischemic stroke, vascular complications, and renal replacement therapy during hospitalization. Propensity score matching was performed to compare the outcomes between the groups. We performed sensitivity analyses excluding patients who received extracorporeal cardiopulmonary resuscitation. Results Of 14,525 eligible patients, 603 (4.2%) received ECPella and 13,922 (96%) received ECMO+IABP. After propensity score matching, there was no significant difference in in-hospital mortality between the two groups (58.9% versus 56.6%; risk difference, 2.3%; 95% confidence interval, -3.9% to 8.5%). A Kaplan–Meier analysis with the log-rank test showed no significant difference in the 60-day in-hospital mortality between the two groups (P value = 0.114) (Figure 1). The ECPella group had a longer hospital stay (mean 42.8 days versus 33.7 days; risk difference, 9.1 days; 95% confidence interval, 2.6 to 15.6 days), a higher total hospitalization cost (12,573,000 yen versus 6,857,000 yen; risk differences, 5,716,000 yen; 95% confidence interval, 4,439,000 yen to 6,993,000 yen), and more frequent major bleeding (8.1% versus 5.8%; risk difference, 2.0%; 95% confidence interval, 0.007% to 4.0%), vascular complications (4.1% versus 2.2%; risk difference, 2.0%; 95% confidence interval, 0.04% to 3.9%), and renal replacement therapy during hospitalization (50.6% versus 41.1%; risk difference, 9.5%; 95% confidence interval, 3.0% to 15.9%) than the ECMO+IABP group (Figure 2). The results of the sensitivity analyses, excluding 6,360 patients (44%) who received extracorporeal cardiopulmonary resuscitation, showed similar results to those for the main analyses. Conclusions This nationwide inpatient database study showed that ECPella was not associated with a survival benefit but was associated with a longer hospital stay, a higher total hospitalization cost, and more complications than ECMO+IABP.Figure 1Figure 2

History education research in Türkiye: A bibliometric analysis based on WOS and Scopus data (2000-2023)

This study aims to exhibit a bibliometric analysis of history education research in Türkiye. A total of 127 documents from 70 sources indexed in the Web of Science and Scopus databases in the years 2000-2023 were used in the analysis. The analysis provides a review of history education research in Türkiye by identifying the dynamics of research by presenting a wide in-depth knowledge concerning the periodical process, current situation, and future directions. Since 2006, history education studies in Türkiye have become more visible in the relevant databases. The annual increase rate of the studies was determined as 8.49 percent. Among the 127 documents accessed, research articles are the most common with a total of 104 articles. From the analysis, it could be said that history education research in Türkiye is mostly conducted in Turkish journals and by Turkish authors. Compared to international literature in history education, studies on ‘historical consciousness’ in Türkiye that were indexed in WOS and Scopus databases were found to be rare in the analysis. Despite this, it is observed that new approaches have started to be studied within the framework of concepts such as 'oral history', 'postmodernism', and 'museum education' in history education studies originating from Türkiye that were indexed in WOS and Scopus databases. In the analysis, it has been observed that although academic studies in qualified databases originating from Türkiye in the field of history education are not sufficient, they have been on an increasing trend in recent years.

Combined association between dietary antioxidant quality score and leisure-time physical activity on sleep pattern in cancer survivors: a cross-sectional study of NHANES database.

This study aimed to explore the combined association between the dietary antioxidant quality score (DAQS) and leisure-time physical activity on sleep patterns in cancer survivors. Data of cancer survivors were extracted from the National Health and Nutrition Examination Surveys (NHANES) database in 2007-2014 in this cross-sectional study. Weighted multivariable logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association of DAQS and leisure-time physical activity on sleep patterns. The combined association was also assessed in subgroups of participants based on age, and use of painkillers and antidepressants. Among the eligible participants, 1,133 had unhealthy sleep patterns. After adjusting for covariates, compared to low DAQS level combined with leisure-time physical activity level <600 MET·min/week, high DAQS level combined with leisure-time physical activity ≥600 MET·min/week was associated with lower odds of unhealthy sleep patterns (OR=0.41, 95%CI: 0.23-0.72). Additionally, the association of high DAQS level combined with high leisure-time physical activity with low odds of unhealthy sleep patterns was also significant in <65 years old (OR=0.30, 95%CI: 0.13-0.70), non-painkiller (OR=0.39, 95%CI: 0.22-0.71), non-antidepressant (OR=0.49, 95%CI: 0.26-0.91) and antidepressant (OR=0.11, 95%CI: 0.02-0.50) subgroups. DAQS and leisure-time physical activity had a combined association on sleep patterns in cancer survivors. However, the causal associations of dietary nutrient intake and physical activity with sleep patterns in cancer survivors needs further clarification.

Identification of JAZF1, KNOP1, and PLEKHA1 as causally associated genes and drug targets for Alzheimer's disease: a summary data-based Mendelian randomization study.

There is a growing body of evidence indicating the significant role of the immune system and immune cells in the progression of Alzheimer's disease (AD). However, the exact role of genes from various immune cell types in AD remains unclear. We aimed to utilize summary data-based Mendelian randomization (SMR) to explore the potential causal relationships between genes in specific immune cells and the risk of AD. By utilizing data sets of expression quantitative trait loci (eQTL) for 14 different immune cell types and large-scale AD genome-wide association study (GWAS), we employed SMR to identify key genes associated with AD within specific immune cells. Sensitivity analyses, including F-statistic, colocalization, and assessment of horizontal pleiotropy, were further conducted to validate the discovered genes. In addition, replication analyses were performed in AD GWAS from the FinnGen consortium. Finally, we further identified existing drugs that target or interact with the druggable genes and reviewed the studies about the associations between these drugs and AD. SMR analysis revealed 342 genes associated with AD across 14 immune cell types. Further sensitivity analyses identified nine genes, CTSH, FCER1G, FNBP4, HLA-E, JAZF1, KNOP1, PLEKHA1, RP11-960L18.1, and ZNF638 that had significant associations with AD across nine specific immune cell types. JAZF1, KNOP1 and PLEKHA1 were replicated in an independent analysis usingthe GWAS data. The review on gene-related drugs also supported these findings. Our research suggests that the expression of the genes JAZF1, KNOP1, and PLEKHA1 in specific immune cell types is related to the risk of AD.

Incidence rates of hepatocellular carcinoma based on risk stratification in steatotic liver disease for precision medicine: A real-world longitudinal nationwide study.

Detailed subgroup incidence rates for steatotic liver disease (SLD)-related hepatocellular carcinoma (HCC) are critical to inform practice and public health interventions but remain sparse. We aimed to fill in this gap. In a retrospective cohort study of adults with SLD from the United States (US) Merative Marketscan Research Databases (1/2007 to 12/2021), we estimated HCC incidence stratified by sex, age, cirrhosis, diabetes mellitus (DM), and a combination of all these 4 factors. We excluded patients with significant alcohol use and chronic viral hepatitis. We analyzed data from 741,816 patients with SLD (mean age 51.5 ± 12.8 years, 46% male, 14.7% cirrhosis). During a 2,410,166 person-years (PY) follow-up, 1,740 patients developed HCC. The overall HCC incidence yielded 0.72 per 1,000 PY (95% confidence interval [CI, 0.68, 0.75]). The incidence was higher in males (0.95, 95% CI [0.89, 1.01]) compared to females (0.52, 95% CI [0.48, 0.56]) (p < 0.001). For those with cirrhosis, the incidence was significantly higher at 4.29 (95% CI [4.06, 4.51]) compared to those without cirrhosis (0.14, 95% CI [0.13, 0.16]) (p < 0.001). Additionally, the incidence was higher in patients with DM (1.19, 95% CI [1.12, 1.26]) compared to those without DM (0.41, 95% CI [0.38, 0.44]) (p < 0.001). Chronic kidney disease (CKD) was also associated with a higher HCC incidence of 2.20 (95% CI [2.00, 2.41]) compared to those without CKD (0.58, 95% CI [0.55, 0.62]) (p < 0.001). Similarly, individuals with cardiovascular disease (CVD) had a higher HCC incidence of 1.89 (95% CI [1.75, 2.03]) compared to those without CVD (0.51, 95% CI [0.48, 0.54]) (p < 0.001). Finally, the incidence of HCC was significantly higher in patients with non-liver cancer (3.90, 95% CI [3.67, 4.12]) compared to those without other cancers (0.29, 95% CI [0.26, 0.31]) (p < 0.001). On further stratification, HCC incidence incrementally rose by 10-year age intervals, male sex, cirrhosis, and DM, reaching 19.06 (95% CI [16.10, 22.01]) and 8.44 (95% CI [6.78, 10.10]) in males and females, respectively, but only 0.04 for non-diabetic, noncirrhotic aged <40 years patients in both sexes. The main limitation of this methodology is the potential misclassification of the International Classification of Diseases (ICD) codes inherent in claims database studies. This nationwide study provided robust granular estimates for SLD-related HCC incidence stratified by several key risk factors. In addition to cirrhosis, future surveillance strategies, prevention, public health initiatives, and future research models should also take into account the impact of sex, age, and DM.

Pseudophakic cystoid macular edema.

Pseudophakic cystoid macular edema (PCME) is the most common postoperative complication of cataract surgery, resulting in visual decline. In this review, we discuss its pathophysiology, epidemiology, clinical presentation, and the current available evidence on therapeutic management. Patients with diabetes mellitus have twice the risk of developing PCME as compared to nondiabetic individuals. Recent large database studies have revealed an increased risk among young, male, and black patients. A previous history of PCME is perhaps the strongest risk factor for fellow eye involvement. PCME generally occurs around 6 weeks postoperatively and is likely a consequence of postoperative inflammation with disruption of the blood-queous and blood-retina barriers. Optical coherence tomography of the macula servers as a key diagnostic tool. There is a lack of large controlled clinical trials to guide treatment approaches. We recommend a stepwise approach for PCME that includes observation if not visually significant versus treatment with topical nonsteroidal anti-inflammatory drugs and steroids if symptomatic. Refractory cases can be treated with a periocular steroid injection, followed by intravitreal steroids if still nonresponsive.

Early use of long-acting injectable antipsychotics in bipolar disorder type I: An expert consensus.

Long-acting injectable antipsychotics (LAIs) are not routinely offered to patients living with bipolar disorder type I (BP-I), despite widespread evidence that supports their benefits over oral antipsychotics, particularly in early disease. A round-table meeting of psychiatrists convened to discuss barriers and opportunities and provide consensus recommendations around the early use of LAIs for BP-I. LAIs are rarely prescribed to treat BP-I unless a patient has severe symptoms, sub-optimal adherence to oral antipsychotics, or has experienced multiple relapses. Beyond country-specific accessibility issues (e.g., healthcare infrastructure and availability/approval status), primary barriers to the effective use of LAIs were identified as attitudinal and knowledge/experience-based. Direct discussions between healthcare providers and patients about treatment preferences may not occur due to a preconceived notion that patients prefer oral antipsychotics. Moreover, as LAIs have historically been limited to the treatment of schizophrenia and the most severe cases of BP-I, healthcare providers might be unaware of the benefits LAIs provide in the overall management of BP-I. Improved treatment adherence associated with LAIs compared to oral antipsychotics may support improved outcomes for patients (e.g., reduced relapse and hospitalization). Involvement of all stakeholders (healthcare providers, patients, and their supporters) participating in the patient journey is critical in early and shared decision-making processes. Clinical and database studies could potentially bridge knowledge gaps to facilitate acceptance of LAIs. This review discusses the benefits of LAIs in the management of BP-I and identifies barriers to use, while providing expert consensus recommendations for potential solutions to support informed treatment decision-making.

The COMPARE Study: Comparing Perioperative Outcomes of Oncologic Minimally Invasive Laparoscopic, Da Vinci Robotic, and Open Procedures: A Systematic Review and meta-analysis of The Evidence.

To assess 30-day outcomes of da Vinci robotic-assisted (dV-RAS) versus laparoscopic/thoracoscopic (lap/VATS) or open oncologic surgery. Complex procedures in deep/narrow spaces especially benefit from dV-RAS. Prior procedure-specific comparisons are not generalizable. PubMed, Scopus and EMBASE were systematically searched (latest: 11/17/2023) following PRISMA and PROSPERO (Reg#CRD42023466759). Randomized, prospective, and database studies were pooled as odds ratios (OR) or mean differences (MD) in R using fixed-effect or random-effects (heterogeneity significant). ROBINS-I/RoB 2 were used to assess bias. Of 56,314 unique references over 12 years from 22 countries, 230 studies (34 randomized, 74 prospective, 122 database) comparing dV-RAS to lap/VATS or open surgery across 7 procedures, 4 specialties, representing 1,194,559 dV-RAS; 1,095,936 lap/VATS and 1,625,320 open cases were included. Operative time for dV-RAS was longer than lap/VATS (MD:17.73min [9.80,25.67], P<0.01) and open surgery (MD:40.92min [28.83,53.00], P<0.01), whereas hospital stay was shorter (lap/VATS MD:-0.51d [-0.64,-0.38], P<0.01; open MD:-1.85d [-2.09,-1.62], P<0.01) and blood loss was less versus open (MD:-293.44ml [-359.53,-227.35]). There were fewer dV-RAS conversions (OR:0.44 [0.40,0.49], P<0.01), transfusions (OR:0.79 [0.72,0.88], P<0.01), postoperative complications (OR:0.90 [0.84,0.96], P<0.01), readmissions (OR:0.91 [0.83,0.99], P=0.04), and deaths (OR:0.86 [0.81,0.92], P<0.01) versus lap/VATS, and fewer transfusions (OR:0.25 [0.21,0.30], P<0.01), postoperative complications (OR:0.56 [0.52,0.61], P<0.01), readmissions (OR:0.71 [0.63,0.81], P<0.01), reoperations (OR:0.89 [0.81,0.97], P<0.01), and deaths (OR:0.54 [0.47,0.63], P<0.01) versus open surgery. Blood loss (MD:-12.26mL [-29.44,4.91], P=0.16) and reoperations (OR:1.03 [0.95,1.11], P=0.48) were similar for dV-RAS and lap/VATS. There was significant heterogeneity. Da Vinci-RAS confers benefits across oncological procedures and study designs. These results provide clinical evidence to multi-specialty-care decision-makers considering dV-RAS.
