The impact of adherence to NCCN and BCLC treatment guidelines on survival in HCC: A single center study.

561 Background: Hepatocellular carcinoma (HCC) is a prevalent and lethal disease in Saudi Arabia, and globally. Guidelines such as Barcelona Clinic Liver Cancer (BCLC) and National Comprehensive Cancer Network (NCCN) are used to guide therapy for this disease. Adherence to these guidelines should lead to better outcomes. We aim to examine the adherence to guidelines and its impact on survival in a real world setting. Methods: This retrospective cross-sectional study was conducted at the Ministry of National Guard for Health Affairs, Riyadh, Saudi Arabia. Study included all adult patients with HCC who were diagnosed between 2020 and 2023, and presented at our HCC multidisciplinary tumor board (MDT). Data extracted included demographics, clinical and disease characteristics, treatment modalities, and survival status. Chi-square tests, and Kaplan-Meier survival analysis were used to explore relationships between tumor characteristics, adherence to NCCN and BCLC guidelines, and survival outcomes. Adherence to guidelines were assessed by two independent physicians. Results: The study included 208 patients with HCC, the majority were males (73%) with a mean age of 73 years. Less than half of the patients (41.7%) had an Eastern Cooperative Oncology Group (ECOG) performance status of 1. Tumor staging showed that 35% of the patients had BCLC stage D. Child pugh class A and B were equally present in 45% of the patients. Moreover, 24% of the patients had distant metastases or vascular invasion (in portal vein) placing them in BCLC stage C. It is noteworthy that Alpha-Fetoprotein (AFP) was abnormal (>8ng/ml) in 58% of the patients, 18% of them had AFP of more than 400ng/ml. Additionally, the prevalence of comorbid conditions were remarkable for liver cirrhosis being present in 85% of patients, while diabetes mellitus and hypertension each present in 63% of patients. Finally, survival analysis showed a median survival of 16.8 months in all patients with HCC (range 0-47.8 months). Adherence to guidelines were high, with 97.6% (n=203) following NCCN guidelines and 70.7% (n=147) following BCLC guidelines. Following both guidelines showed better survival with mean of 37 months (SD=1.841) in patients with child pugh class A (n=53), and mean survival of 24 months (SD=2.251) in patients with child pugh class B (n=74). Conclusions: Adherence to NCCN guidelines was high in our MDT presented patients compared to BCLC guidelines adherence which was lower, but with comparable survival outcomes.

Multimodal large language models address clinical queries in laryngeal cancer surgery: a comparative evaluation of image interpretation across different models.

Recent advances in multimodal large language models (MLLMs) have shown promise in medical image interpretation, yet their utility in surgical contexts remains unexplored. This study evaluates six MLLMs' performance in interpreting diverse imaging modalities for laryngeal cancer surgery. We analyzed 169 images (X-rays, CT scans, laryngoscopy, and pathology findings) from 50 patients using six state-of-the-art MLLMs. Model performance was assessed across 1084 clinically relevant questions by two independent physicians. Claude 3.5 Sonnet achieves the highest accuracy (79.43%, 95% CI: 77.02%-81.84%). Performance varied significantly across imaging modalities and between commercial and open-source models, with a 19-percentage point gap between the best commercial and open-source solutions. Advanced MLLMs show promising potential as clinical decision support tools in laryngeal cancer surgery, while performance variations suggest the need for specialized model development and clinical workflow integration. Future research should focus on developing specialized MLLMs trained on large-scale multi-center laryngeal cancer datasets.

Isolated subsegmental pulmonary embolism identification based on international classification of diseases (ICD)-10 codes and imaging reports.

Isolated subsegmental pulmonary embolism (issPE) is a commonly encountered diagnosis. Although the International Classification of Diseases (ICD)-10 codes are used for research, their validity for identifying issPE is unknown. Moreover, issPE diagnosis is challenging, and the findings from radiology reports may conflict with those from expert radiologists. Based on prespecified criteria, 1734 medical records of adult patients hospitalized within the Mass General Brigham health system (2016-2021) were selected in three equal groups: (1) patients with principal discharge diagnosis codes for PE, (2) patients with secondary discharge diagnosis codes for PE, and (3) patients with no PE codes. The accuracy of ICD-10 codes for issPE was verified by two independent physicians and weighted by total hospitalizations. In a randomly selected sample of 70 patients, the accuracy of initial radiology reports was determined through a blinded re-evaluation by two expert radiologists. In weighted estimates, ICD-10 codes in primary or secondary discharge positions, compared with chart reviews, showed a low sensitivity (7.0%) and positive predictive value (25.2%). Evaluation by two expert radiologists noted that initial radiology reports were sensitive (97.1%) for issPE but had a low specificity (40.0%). Two (3.6%) out of 55 patients with initial issPE reports did not have PE, while 19 (34.5%) had more proximal PE. ICD-10 codes for issPE have poor sensitivity and positive predictive value and should not be used for research or quality improvement. Radiology reports for issPE may be inaccurate regarding the location or, less often, the presence of PE.

Improving Atrial Fibrillation or Flutter Detection and Management by Smartphone-Based Photoplethysmography Rhythm Monitoring Following Cardiac Surgery: A Pragmatic Randomized Trial.

Atrial fibrillation (AF) or atrial flutter (AFL) after cardiac surgery are common and associated with adverse outcomes. The increased risk related to AF or AFL may extend beyond discharge. This study aims to determine whether photoplethysmography (PPG)-based smartphone monitoring to detect AF or AFL after hospital discharge following cardiac surgery improves AF management. The intervention group performed one-minute rhythm checks three times daily using a smartphone-based PPG application during six weeks after hospitalization for cardiac surgery. The primary outcome involved AF management interventions by independent physicians, including initiation of oral anticoagulation (OAC), direct cardioversion and up-titration or initiation of antiarrhythmic drugs. The study included 450 patients (mean [SD] age, 64.1 [9.2] years; 96 women [21.3%]; 130 patients with AF history [28.9%]; median [IQR] CHA2DS2-VASc score, 2 [1-3]), of whom 238 were randomized to PPG-based monitoring and 212 to usual care. AF/AFL was detected with PPG or electrocardiography in 44 patients (18.5%) in the monitoring group and 4 patients (1.9%) in the usual care group (OR 11.8; 95%CI, 4.2-33.3; P<.001), these were new detections in respectively 22 patients (9.2%) and 1 patient (0.5%) (OR 21.3; 95%CI, 2.9-166.7; P=.003). AF management interventions occurred in 24 patients (10.1%) in the monitoring group compared to 5 patients (2.4%) in the usual care group (odds ratio [OR]), 5.1; 95%CI, 1.8-14.4; P=.002). In unselected patients discharged home following cardiac surgery, PPG-based smartphone monitoring revealed significantly more AF/AFL which led to significantly more optimization of AF management.

How do hospitals exert market power? Evidence from health systems and commercial health plan prices.

Consolidation of independent hospitals and physician practices into integrated health systems has reshaped the delivery of health care. While the literature suggests that provider consolidation raises prices, few studies have examined the interplay of health systems and insurers in relation to prices. Using negotiated price data that commercial insurers recently released under the Transparency in Coverage Final Rule, we examined the association between hospital concentration under health systems and prices for outpatient procedures in local health care markets with different levels of insurer concentration. We found that hospital prices are higher in more concentrated hospital markets, while lower in more concentrated insurer markets. However, the negative relationship between insurer concentration and hospital prices is attenuated in highly concentrated hospital markets, suggesting that insurers' bargaining leverage is lessened at greater levels of hospital consolidation. Considering the continued consolidation among hospitals and vertical integration of physician practices into health systems, our findings suggest that commercial payers may encounter increased challenges in controlling health care spending for their beneficiaries as providers' bargaining power continues to grow.

Injury incidence and associated factors among soccer players during the 2021 African Cup of Nations competition

Background Understanding the epidemiology of soccer injuries during specific international competitions is essential for customizing preventive strategies. Several studies have reported outcomes related to international competitions but, to the best of our knowledge, there has been no investigation into the injury patterns during any African Cup of Nations (AFCON) tournaments. This study aimed to analyse the incidence and the characteristics of soccer injuries during the 2021 African Cup of Nations (AFCON), which took place in Cameroon from January 9 to February 6, 2022. Methods A video-based analysis covering 52 matches was conducted by two independent consultant physicians. They reviewed injury replays to determine incidence and characteristics ( i.e. ; mechanisms, body location, match moment, player substitution, absence in the next match, and referee decisions). Results The tournament involved 519 male players, comprising 275 African (ALP) and 244 Non-African (NALP) league players. Eighty-seven injuries occurred, with incidences of 1.7 and 48.8 injuries per match and per 1000 match hours, respectively. Injury incidence rose with competition stages, particularly contact mechanism injuries. Non-contact injuries (23/87) predominantly occurred after 60 minutes of play (19/23), with the thigh being the most frequently affected body part (18/87). Older age and playing time significantly correlated with injury occurrence (p=0.032 and p&lt;0.001, respectively). NALP midfielders and forwards were notably injured by contact mechanisms (36/45) in the attacking zone. Although non-contact mechanisms were more common in ALP than NALP (13/42 vs. 9/45), the difference lacked statistical significance (p=0.240), with a higher rate of muscle injuries (13/42 vs. 10/45, p=0.001). Conclusion Muscle injuries prevailed among professional soccer players in the 2021 AFCON, with older age and playing time identified as key associated factors. Muscle injuries were more prevalent in ALP compared to NALP.

Comparative Electrocardiographic Analysis Between Physical Exercise Practitioners and Athletes: A Cross-Sectional Study.

The trained heart adapts through geometric changes influenced by concentric and eccentric hypertrophy, depending on the predominance of the isometric or dynamic components of the exercise performed. Additionally, alterations in heart rhythm may occur due to increased vagal system activity. Cardiological evaluation with an electrocardiogram (ECG) aims to identify cardiac conditions that could temporarily or permanently disqualify an athlete from competition. This study sought to compare electrocardiographic findings in regular exercisers with those observed in athletes and to correlate these findings with training duration and load. A cross-sectional study was conducted with 154 participants divided into two groups: exercisers (EG) and athletes (AG). Data were collected on exercise type, weekly training time and practice duration. Each participant underwent a resting ECG, analyzed by two independent physicians, with a third review in case of disagreement. The Seattle criteria were applied to categorize ECG changes as physiological, borderline or abnormal. The findings revealed that 75% of athletes exhibited ECG changes, with left and/or right ventricular hypertrophy and incomplete right bundle branch block (IRBBB) being the most prevalent. Age (PR = 0.92; p = 0.004) and exercise duration (PR = 1.00; p = 0.004) significantly influenced the observed electrocardiographic changes. The majority of both regular exercisers and athletes displayed ECG alterations, with the prevalence increasing with age and training duration.

Role of cardiac and lung ultrasonography in predicting weaning failure in patients with acute kidney injury requiring mechanical ventilation: A pilot study.

Acute Kidney Injury (AKI) has an incidence of 20-50% in patients admitted in Intensive Care Unit. As weaning failure is associated with increased morbidity, its prediction and understanding of its physiological basis holds extreme importance in guided management and prognostication of these patients. We conducted this prospective, observational, single - center study to evaluate the efficacy of transthoracic echocardiography (TTE) and lung ultrasonography (LUS) in predicting weaning failure in patients with AKI requiring mechanical ventilation. We performed LUS and TTE before and 2h after initiating spontaneous breathing trials (SBT) in 32 mechanically ventilated critically ill patients with AKI. Extubation was decided by an independent physician. LUS included global and anterior LUS scores. TTE included measurement of E/A and E/e' ratios to determine LV filling pressures. Out of 32 patients included in this study, weaning failure was observed in 17 (n = 17, 53%) patients (weaning success n=15, 47%). Demographic and baseline laboratory parameters were comparable between the study groups. Fluid balance [+370 (250-530)] and SOFA score [8 (7-9)] on admission were significantly higher in weaning failure group (p<0.001, p=0.049). LUS scores and difference between LUS scores before and at the end of the SBT were significantly higher among the weaning failure group. The model consisting of baseline variables, SOFA score on the day of weaning and SBT induced changes in global lung score showed highest ability to predict weaning failure with AUC of 0.965, R2=61%, p<0.001. In mechanically ventilated critically ill patients with AKI, LUS scores can predict weaning failure after SBT. CTRI/2020/12/029565.

Three-dimensional printing technology for the positioning of the reconstructed auricle in microtia reconstruction.

The positioning of the reconstructed ear in ear reconstruction is a crucial step that directly affects the surgical outcome.This study employs the residual ear tissue as a reference, in conjunction with three-dimensional(3D)printing model of the normal ear's mirror image corresponding to the microtia ear, to facilitate precise positioning during the reconstruction of the ear. This study established a 3D model group and a control group. The 3D model group utilized 3D printed models of residual ear tissue alongside the mirror image of the normal ear for positioning, while the control group relied on the surgeon's subjective observation.The symmetry of the reconstructed ear post-operation was evaluated by two independent physicians who were not involved in the surgical procedure for the patients.The patient was asked to use the Visual Analog Scale (VAS) to assess their satisfaction with ear symmetry and ear shape preoperative and postoperative 12 months. A total of 84 patients who met the inclusion criteria were enrolled in this study.In the 3D model group, no statistically significant differences were observed between the average distances from the highest and lowest points of the normal ear to the nasal axis and those of the reconstructed ear(P=0.688, P=0.916). Conversely, a statistically significant difference was noted in the control group (P=0.041; P=0.028).The 3D model group exhibited higher total scores on the VAS for patients' objective satisfaction CONCLUSION: The reconstructed ear can be accurately positioned by utilizing the residual ear tissue as a reference and employing 3D printing model with mirror technology.

Health System Expansion and Changes in Medicare Beneficiary Utilization of Safety Net Providers.

Evidence is limited on insured patients' use of safety net providers as vertically integrated health systems spread throughout the United States. To examine whether market-level health system penetration is associated with: (1) switches in Medicare beneficiaries' usual source of primary care from federally qualified health centers (FQHCs) to health systems; and (2) FQHCs' overall Medicare patient and visit volume. Beneficiary-level discrete-time survival analysis and market-level linear regression analysis using Medicare fee-for-service claims data from 2013 to 2018. A total of 659,652 Medicare fee-for-service beneficiaries aged 65 and older lived in one of 27,386 empirically derived primary care markets whose usual source of care in 2013 was an FQHC or a non-FQHC-independent physician organization that predominantly served low-income patients. Beneficiary-year measure of the probability of switching to health system-affiliated physician organizations and market-year measures of the number of FQHC visits by Medicare beneficiaries, number of beneficiaries attributed to FQHCs, and FQHC Medicare market shares. During 2013-2018, 16.5% of beneficiaries who sought care from FQHCs switched to health systems. When health system penetration increases from the 25th to 75th percentile, the probability of Medicare FQHC patient switching increases by 4.6 percentage points, with 22 fewer Medicare FQHC visits and 4 fewer beneficiaries attributed to FQHCs per market year. Complex patients and patients who sought care from non-FQHC, independent physician organizations exhibited higher rates of switching to health systems. Health system expansion was associated with the loss of Medicare patients by FQHCs, suggesting potential negative spillovers of vertical integration on independent safety net providers.

Relative Cortical Atrophy Index as a Strong Predictor of Recurrence After Surgery for Chronic Subdural Hematoma.

Chronic subdural hematoma (CSDH) presents significant management challenges in neurosurgical practice, with recurrence being a notable postoperative consideration. This study aimed to evaluate the Relative Cortical Atrophy (RCA) Index as a predictor of recurrence after CSDH surgery. A retrospective analysis was conducted on 98 patients who underwent surgical evacuation for unilateral CSDH. The RCA Index was calculated using pre- and postoperative cranial imaging, correlating it with patient demographics, hematoma characteristics, and recurrence. Inter-rater reliability among measurements by 4 independent physicians was assessed using the intraclass correlation coefficient (ICC). Correlation and regression analyses were performed to identify the correlation of the RCA Index with other factors and their potential predicting power of CSDH recurrence, respectively. The study population had a mean age of 74.1 (11.9) years, with a 23.5% (23 patients) recurrence rate of CSDH. The ICC analysis showed excellent inter-rater reliability for RCA Index measurements (ICC: 0.998, 95% CI: 0.997-0.998, P < .001). A higher preoperative RCA Index was significantly associated with recurrence (0.215 [0.031] in the recurrent group vs 0.125 [0.034] in the nonrecurrent group, P < .001). The preoperative RCA Index highly correlated with the postoperative RCA Index (Pearson's correlation: 0.918, P < .001), and there was only a small (average: 0.005) but significant increase in the RCA Index of the unaffected hemisphere after surgery ( P = .01).The preoperative RCA Index positively correlated with age, preoperative SDH thickness and volume, and recurrence. A RCA Index cutoff value of 0.165 predicted CSDH recurrence with high sensitivity (95.6%) and specificity (93.3%) (area under the curve = 0.97, 95% CI: 0.93-1). The RCA Index is a simple yet robust predictor of CSDH recurrence. Incorporating this measure into the preoperative assessment may enhance surgical planning and postoperative management, potentially reducing recurrence rates.

Using Electronic Health Records to Identify the Daily Primary Provider During Hospitalization.

Providers vary in their impact on clinical outcomes, but this is rarely accounted for in healthcare research. By failing to identify the provider responsible for a patient's care, investigators miss an opportunity to account for nonrandom variation in outcomes. Prior methods of identifying responsible providers have relied on manual chart review, which is time-consuming and expensive, or analysis of claims data, which has been demonstrated to be inaccurate. To address these gaps, we sought to develop an algorithm using electronic health record (EHR) data to identify the responsible provider for each day of a patient's hospitalization. A multicenter retrospective cohort study. Midwest healthcare system. Hospitalized patients and their providers. None. We first confirmed high inter-rater reliability of manual chart review to identify the responsible provider. Using manual chart review as the gold standard, we then assessed the accuracy of an automated algorithm in a set of randomly selected patients. The agreement between two independent physicians in their determination of the responsible provider by chart review was 100%. Among 200 randomly selected patients, the algorithm identified the same responsible provider as the physician chart reviewer on 93% (3372/3626; 95% CI, 92-94%) of patient-days. Readily available EHR data can be used to assign patients to providers daily with a high degree of accuracy. This methodology could be applied in healthcare research to identify sources of variation other than the intervention being studied.

Our House Won't Rebuild Itself: Peace, Love, and Hope as Tools to Transform Graduate Medical Education.

Graduate medical education (GME), the period of specialty and subspecialty training following attainment of a medical degree, is the final step in a continuum of medical education culminating in independent physician practice. This manuscript uses the metaphor "our house" to describe all aspects of the GME environment in which health care professionals and trainees learn and work. Our house's inhabitants have unequivocally stated that our house is in a state of disrepair. While physicians-in-training inevitably face challenges on their journey to independent practice, those from historically marginalized backgrounds face these challenges compounded by the disproportionate impact of identity-based harms. The authors use critical and liberatory theories to explore dominant power dynamics in GME, classifying identity-based harms as silence, pain, and despair. To strive for true transformation, the authors advocate for a new set of house rules, a different way of coexisting based on the principles of liberatory design. The authors call on readers to rebuild the house of GME by drawing parallels between the foundational human values of peace, love, and hope and the educational principles of psychological safety, identity safety, and belonging. To transform GME, our community must make space in our house for all individuals to join and, indeed, to rebuild together.

A Validated Electronic Medical Record-Based Algorithm to Identify Hospitalized Patients with Serious Illness.

Background: Population-based methods to identify patients with serious illness are necessary to provide equitable and efficient access to palliative care services. Aim: Create a validated algorithm embedded in the electronic medical record (EMR) to identify hospitalized patients with serious illness. Design: An initial algorithm, developed from literature review and clinical experience, was twice adjusted based on gaps identified from chart review. Each iteration was validated by comparing the algorithm's results for a subset of patients (approximately 10% of the populations screened in and screened out on a given day) with the expert consensus of two independent palliative care physicians. Settings/Subjects: The final algorithm was run daily for nine months to screen all hospitalized adults at our academic medical center in the United States. Results: Compared with the gold standard of expert consensus, the final algorithm for identifying hospitalized patients with serious illness was found to have a sensitivity of 89%, specificity of 82%, positive predictive value of 80%, and negative predictive value of 90%. At our hospital, an average of 284 patients a day (54%) screened positive for at least one criterion, with an average of 38 patients newly screening positive daily. Conclusions: Data from the EMR can identify hospitalized patients with serious illness who may benefit from palliative care services, an important first step in moving to a system in which palliative care is provided proactively and systematically to all who could benefit.

18F]PSMA-1007 PET for biochemical recurrence of prostate cancer, a comparison with [18F]Fluciclovine.

The objective of this study was to compare the detection rates of [18F]PSMA-1007 and [18F]Fluciclovine in early biochemical recurrence (BCR) of prostate cancer, i.e. with low prostate-specific antigen (PSA) levels (0.2-5.0µg/L). This was a prospective, single-center (Radboudumc; Nijmegen, The Netherlands), comparative phase II diagnostic imaging study (NCT04239742). The main inclusion criteria were histologically proven adenocarcinoma of the prostate, BCR after radical treatment with two consecutive (rising) PSA values (0.2-5.0µg/L). Patients underwent both [18F]PSMA-1007 PET/CT and [18F]Fluciclovine PET/CT within two weeks. Both scans were blindly scored by three independent nuclear medicine physicians. Hereafter, a result per scan and region was generated by consensus. The primary outcome was to compare the detection rate on a patient and region level. Secondary objectives were to determine detection rate stratified for PSA value, inter-reader agreement, and SUV measurements. For lesion confirmation a composite reference score was established using follow-up data. Data of fifty patients were included, median age of 71 (IQR: 67-74) years and median PSA value of 0.38 (IQR: 0.30-1.55) µg/L. Detection rates were 68% (34/50) for [18F]PSMA-1007 and 42% (21/50) for [18F]Fluciclovine on a patient level (p < 0.001). Detection rates stratified for PSA value of [18F]PSMA-1007 in comparison with [18F]Fluciclovine were for PSA 0.2-0.5µg/L; 60.7% versus 25.0% (p = 0.002); and for PSA ≥ 0.5µg/L; 77.3% versus 63.6% (p = 0.250). There was a trend for higher inter-reader agreement with [18F]PSMA-1007. SUVmax (p < 0.001) was significantly higher for [18F]PSMA-1007 in comparison to [18F]Fluciclovine. In patients with early BCR of prostate cancer after radical surgery or radiotherapy, [18F]PSMA-1007 demonstrated a significantly higher detection rate than [18F]Fluciclovine. This is particularly relevant since earlier and more accurate detection of a BCR can guide salvage therapy into a tailored strategy which may improve outcomes. ClinicalTrials.gov, NCT04239742.

Assessing the Reliability of the Bleeding Assessment Scale in Critically Ill Children (BASIC) Definition: A Prospective Cohort Study.

To determine the reliability of the Bleeding Assessment Scale in critically Ill Children (BASIC) definition of bleeding severity in a diverse cohort of critically ill children. Prospective cohort study. Eight mixed PICUs in the Netherlands, Israel, and the United States. Children ages 0-18 years admitted to participating PICUs from January 1, 2020, to December 31, 2022, with bleeding noted by bedside nurse. None. The bleeding events were classified as minimal, moderate, or severe, according to the BASIC definition, by two independent physicians at two different time points. Patient demographic data, laboratory values, and clinical outcomes were collected. Three hundred twenty-eight patients were enrolled. The overall inter-rater reliability was substantial (weighted kappa coefficient, 0.736; 95% CI, 0.683-0.789), and the intra-rater reliability was "almost-perfect" (weighted kappa coefficient, 0.816; 95% CI, 0.769-0.863). The platelet count (p = 0.008), prothrombin time (p = 0.004), activated partial thromboplastin time (p = 0.025), and fibrinogen levels (p = 0.035) were associated with the bleeding severity, but the international normalized ratio was not (p = 0.195). Patients were transfused blood components in response to any bleeding in 31% of cases and received hemostatic medications in 9% of cases. More severe bleeding was associated with increased 28-day mortality, longer hospital length of stay, and more days receiving inotropic support. The BASIC definition is a reliable tool for identifying and classifying bleeding in critically ill children. Implementing this definition into clinical and research practice may provide a consistent and reliable evaluation of bleeding.

Validating International Classification of Diseases Code 10th Revision algorithms for accurate identification of pulmonary embolism

BackgroundMany research investigations for pulmonary embolism (PE) rely on the International Classification of Diseases 10th Revision (ICD-10) codes for analyses of electronic databases. The validity of ICD-10 codes in identifying PE remains uncertain. ObjectivesThe objective of this study was to validate an algorithm to efficiently identify pulmonary embolism using ICD-10 codes. MethodsUsing a prespecified protocol, patients in the Mass General-Brigham hospitals (2016-2021) with ICD-10 principal discharge codes for PE, those with secondary codes for PE, and those without PE codes were identified (n = 578 from each group). Weighting was applied to represent each group proportionate to their true prevalence. The accuracy of ICD-10 codes for identifying PE was compared with adjudication by independent physicians. The F1 score, which incorporates sensitivity and positive predictive value (PPV), was assessed. Subset validation was performed at Yale-New Haven Health System. ResultsA total of 1712 patients were included (age: 60.6 years; 52.3% female). ICD-10 PE codes in the principal discharge position had sensitivity and PPV of 58.3% and 92.1%, respectively. Adding secondary discharge codes to the principal discharge codes improved the sensitivity to 83.2%, but the PPV was reduced to 79.1%. Using a combination of ICD-10 PE principal discharge codes or secondary codes plus imaging codes for PE led to sensitivity and PPV of 81.6% and 84.7%, respectively, and the highest F1 score (83.1%; P < .001 compared with other methods). Validation yielded largely similar results. ConclusionAlthough the principal discharge codes for PE show excellent PPV, they miss 40% of acute PEs. A combination of principal discharge codes and secondary codes plus PE imaging codes led to improved sensitivity without severe reduction in PPV.

The Dutch practice of euthanasia and assisted suicide in patients suffering from psychiatric disorders: a qualitative case review study.

Euthanasia or assisted suicide (EAS) in patients suffering from a psychiatric disorder (PD) is a controversial topic worldwide. In the Netherlands, this practice is regulated by law. All cases of EAS have to be reported and are assessed by the Regional Euthanasia Review Committees (RTEs), who publish a selection of all cases on their website. To provide insight into the Dutch practice of EAS in patients suffering from a psychiatric disorder. We performed a retrospective case review study in which all published cases of EAS in patients suffering from a PD between 2017 and 2022 were analyzed. Not applicable. Characteristics of patients who died by EAS because of suffering from a PD, characteristics of the reporting physician and consultant(s) and the RTEs assessment of published cases. Of the 72 cases studied, the majority of patients were female (n=48, 67%), suffered from 3 or more conditions (n=38, 53%) and died by euthanasia instead of assistance in suicide (n=56, 78%). In 63% of cases (n=45), the life termination was performed by a physician from the Euthanasia Expertise center (EE). The RTEs' judgement that the case did not meet the due care criteria (n=11) was in all cases related to issues regarding the (advice of the) independent physician or psychiatric expert. This qualitative study shows that the RTEs attach great importance to a careful evaluation procedure of physicians handling EAS requests and to the physician demonstrating ability to reflect on his views, especially when the independent consultant evaluates the case different than the physician. Training for physicians and more transparency in the assessment of EAS requests in patients with a PD may lower the threshold for physicians to handle requests of these patients themselves. Not applicable.

"Folding Fan Flap": A Novel and Dependable Surgical Technique for Crow's Feet Correction by Z-Plasty of Orbicularis Oculi Muscle.

The challenge of crow's feet surgical correction is to minimize the complication caused by orbicularis oculi muscle (OOM) resection while ensuring the operative effect. This study aims to propose a novel technique to solve this problem and evaluate its efficacy. From January 2022 to April 2024, all patients who received "Folding fan flap" in our institution were included. The outer third of the OOM below the lateral canthus was dissected and received Z-plasty to exchange width for length and reconstruct the muscle dynamics in a non-circular direction. Preoperative and postoperative smiling crow's feet were assessed by two independent physicians using the Lemperle wrinkle scale. At least six months after surgery, patient satisfaction with wrinkle correction, naturalness of facial expression, and local flattening was subjectively evaluated on a five-point scale. Complications including hematomas, incomplete eyelid closure, facial stiffness, and forehead numbness were recorded. A total of 32 patients (63 sides) were included with a mean follow-up of 13.9 ± 5.2 months. Postoperative assessments showed a significant reduction in Lemperle's score from 4.8 ± 0.4 to 1.5 ± 0.5 (P=0.000). Regarding the satisfaction of surgical outcomes and the naturalness of facial expressions, thirty patients (93.8%) were very satisfied. There were no severe complications such as hematomas and incomplete eyelid closure. Preliminary clinical studies demonstrated the efficacy of this technique in ensuring outcomes while preserving normal dynamic expressions. By Z-plasty of the outer circle of OOM, the muscle dynamic was successfully modified rather than eradicated. This journal requires that authors assign a level of evidence to each article.

Predictive value of apical rocking and septal flash for subclinical left ventricular systolic dysfunction in complete left bundle branch block patients with normal left ventricular ejection fraction

BackgroundThis study aimed to evaluate the effects of apical rocking(ApRock) and septal flash(SF) on left ventricular function in complete left bundle branch block(CLBBB) patients with normal left ventricular ejection fraction(LVEF), with the goal of improving risk stratification and clinical decision-making for these patients. MethodsSeventy-five CLBBB patients with normal LVEF, and 30 age- and sex-matched controls were enrolled in the study. Three independent physicians visually assessed the presence of ApRock and SF and left ventricular global longitudinal strain(LVGLS) and the standard deviation of time-to-peak strain in 18 segments(Ts-SD) were evaluated using two-dimensional speckle-tracking echocardiography. ResultsCLBBB patients with normal LVEF had significantly decreased LV function and synchrony as evidenced by LVGLS and Ts-SD, and CLBBB patients with either ApRock or SF had lower LVGLS than those without ApRock or SF. LVGLS were further decreased and Ts-SD was further increased in CLBBB patients with both ApRock and SF (P < 0.001). Logistic regression analysis revealed that both ApRock (OR, 4.13; P = 0.04) and SF (OR, 4.12; P = 0.03) were independently associated with LVGLS>-20 %. Combination of ApRock and SF showed the highest area under the curve for identifying LVGLS>-20 %. Furthermore, combination of ApRock and SF improved reclassification compared to ApRock alone. ConclusionCLBBB patients with normal LVEF showed impaired left ventricular systolic function. The presence of both ApRock and SF was a stronger indicator of subclinical left ventricular impairment compared to either one alone, suggesting that increased attention should be paid to CLBBB patients with normal LVEF, particularly those with both ApRock and SF.
