Effect of Laser Auriculotherapy on Quality of Life, Fatigue, and Anxiety in Women with Advanced Breast Cancer: Randomized Clinical Trial

Objective: To evaluate the effect of laser auriculotherapy on health-related quality of life, cancer-related fatigue, and anxiety in women with advanced breast cancer undergoing palliative chemotherapy. Method: A randomized, parallel, single-blind, single-center clinical trial was conducted in a Brazilian oncology referral hospital. A total of 123 women were randomly divided into groups: 41 in the experimental group (10 weekly laser auriculotherapy sessions), 40 in the sham group (10 weekly sham sessions), and 42 in the control group. Outcomes were assessed at baseline, 5th week, and 11th week, using the Quality of Life Questionnaire Core-30, Functional Assessment of Cancer Therapy: Fatigue and State-Trait Anxiety Inventory. Statistical analyses included Kruskal–Wallis, Mann–Whitney, and Friedman tests. Results: The experimental group exhibited the highest mean overall quality of life, with a significant increase (p < 0.000001) between the second and third evaluations and a significant improvement in fatigue between the second and third evaluations (p = 0.00001). Conversely, women in the sham and control groups experienced a decline and worsening in both their quality of life and fatigue. Women in all three groups showed reduction an anxiety. Changes in anxiety in these women were not statistically significant. Conclusions: reduction improvement in health-related quality of life and a reduction in cancer-related fatigue in the experimental group. These results show a positive effect of auriculotherapy on cancer-related fatigue, demonstrating potential for application in clinical practice in women with advanced breast cancer and in palliative chemotherapy.

Stable Gastric Pentadecapeptide BPC 157 as Therapy After Surgical Detachment of the Quadriceps Muscle from Its Attachments for Muscle-to-Bone Reattachment in Rats

Background: This is a novel rat study using native peptide therapy, focused on reversing quadriceps muscle-to-bone detachment to reattachment and stable gastric pentadecapeptide BPC 157 per-oral therapy for shared muscle healing and function restoration. Methods: Pharmacotherapy recovering various muscle, tendon, ligament, and bone lesions, and severed junctions (i.e., myotendinous junction), per-oral in particular (BPC 157/kg/day 10 µg, 10 ng), provides muscle-to-bone reattachment after quadriceps muscle detachment, both complete (rectus muscle) and partial (vastus muscles). Results: Immediately post-injury, and at 1, 2, 3, 5, 7, 14, 21, 28, 60, and 90 days post-injury, quadriceps muscle-to-bone detachment showed definitive healing failure (impaired walking and permanent knee flexure). Contrarily, macro/microscopic, ultrasonic, magnetic resonance, biomechanical, and functional assessments revealed that BPC 157 therapy recovering effects for all time points were consistent. All parameters of the walking pattern fully improved, and soon after detachment and therapy application, muscle approached the bone, leaving a minimal gap (on ultrasonic assessment), and leg contracture was annihilated. The healing process occurs immediately after detachment from both sides: the muscle and the bone. The reattachment fibers from the ends of the muscle could be traced into the new bone formed at the surface (note, at day 3 post-detachment, increased mesenchymal cells occurred with periosteum reactivation). Consequently, at 3 months, the form was stable, and the balance between the muscle and bone was the following: well-organized bone, newly formed as more cortical bone providing a narrower bone marrow space, and the muscle and mature fibers were oriented parallel to the bone axis and were in close contact with bone. Conclusions: Therefore, to achieve quadriceps muscle-to-bone reattachment, the BPC 157 therapy reversing course acts from the beginning, resolving an otherwise insurmountable deleterious course.

Robotically Assisted vs. Manual Total Hip Arthroplasty in Developmental Hip Dysplasia: A Comparative Analysis of Radiological and Functional Outcomes

Background/Objectives: Developmental dysplasia of the hip (DDH), defined by the malalignment of the femoral head and acetabulum, is a major precursor to coxarthrosis, posing substantial challenges during total hip arthroplasty (THA). Patients with coxarthrosis secondary to DDH often exhibit acetabular bone insufficiency, which makes challenging surgical reconstruction difficult. This study aimed to compare the radiologic and functional outcomes of robotically assisted and conventional manual THA techniques in patients with coxarthrosis secondary to Crowe type III–IV DDH. Methods: This prospective study included 40 patients divided into robotically assisted (n = 20) and conventional manual (n = 20) THA groups. Evaluations encompassed hip pain (Visual Analogue Scale, VAS), function (Harris hip score and University of California, Los Angeles, activity scale), quality of life (Short Form-12), and prosthesis sensation (Forgotten Joint Score-12). Radiologic outcomes included acetabular inclination and anteversion angles. Femoral shortening, operative duration, and follow-up times were also analyzed. Results: Demographic characteristics did not differ between groups (p > 0.05). Robotically assisted THA exhibited a significantly longer operative time (171.40 ± 11.96 vs. 150.30 ± 14.67 min; p = 0.001) but a shorter follow-up (29.3 ± 8.51 vs. 52.95 ± 18.96 months; p = 0.001), without a difference in the amount of femoral shortening (p = 0.947). Despite the extended surgical duration, the two techniques achieved comparable radiologic outcomes, with no significant differences in acetabular inclination or anteversion angles (p > 0.05). Functional assessments, including Harris hip scores (73.85 vs. 73.95; p = 0.978), UCLA activity scores, and VAS, indicated similar efficacy between groups. SF-12 physical and mental quality of life and Forgotten Joint Score-12 prosthesis sensation did not differ between groups (p > 0.05). Conclusions: This study concludes that robotically assisted and conventional manual THA present similar radiologic and functional outcomes in patients with coxarthrosis secondary to Crowe type III–IV DDH, as displayed by comparable acetabular anteversion and inclination alignment, femoral shortening, hip function, pain, quality of life, and prosthesis sensation scores. While robotically assisted THA requires a longer operative time, its precision in implant placement may hold potential advantages for long-term outcomes, demanding further investigation in extended follow-up studies.

Effect of Ficus pumila L. on Improving Insulin Secretory Capacity and Resistance in Elderly Patients Aged 80 Years Old or Older Who Develop Diabetes After COVID-19 Infection

(1) Background: It has been reported that people affected by COVID-19, an infectious disease caused by SARS-CoV-2, suffer from various diseases, after infection. One of the most serious problems is the increased risk of developing diabetes after COVID-19 infection. However, a treatment for post-COVID-19 infection diabetes has not yet been established. In this study, we investigated the effects of Ficus pumila L. extract, which has traditionally been used to reduce blood glucose levels in Okinawa, on patients who developed diabetes after COVID-19 infection. (2) Methods: In total, 128 rehabilitation patients aged 80 years old or older who developed diabetes after COVID-19 infection were included. The HOMA-β (Homeostatic model assessment of β-cell function) and HOMA-IR (Homeostatic model assessment of insulin resistance) were assessed to evaluate the glucose tolerance. (3) Results: The HOMA-β decreased and HOMA-IR increased in patients who developed after diabetes after COVID-19 infection. Subsequently, 59 patients were given Ficus pumila L. extract and their HOMA-β and HOMA-IR improved after ingestion. On the other hand, the control group of patients who did not consume Ficus pumila L. showed no improvement in both HOMA-β and HOMA-IR. (4) Conclusions: Ficus pumila L. extract, ingested by patients who developed diabetes after COVID-19 infection, stimulated insulin secretion capacity and improved insulin resistance.

Long-term memory plasticity in a decade-long connectivity study post anterior temporal lobe resection

Approximately 40% of individuals undergoing anterior temporal lobe resection for temporal lobe epilepsy experience episodic memory decline. There has been a focus on early memory network changes; longer-term plasticity and its impact on memory function are unclear. Our study investigates neural mechanisms of memory recovery and network plasticity over nearly a decade post-surgery. We assess memory network changes, from 3–12 months to 10 years postoperatively, in 25 patients (12 left-sided resections) relative to 10 healthy matched controls, using longitudinal task-based functional MRI and standard neuropsychology assessments. We observe key adaptive changes in memory networks of a predominantly seizure-free cohort. Ongoing neuroplasticity in posterior medial temporal regions and contralesional cingulum or pallidum contribute to long-term verbal and visual memory recovery. Here, we show the potential for sustained cognitive improvement and importance of strategic approaches in epilepsy treatment, advocating for conservative surgeries and long-term use of cognitive rehabilitation for ongoing recovery.

Genetically predicted brain cortical structure mediates the causality between insulin resistance and cognitive impairment

BackgroundInsulin resistance is tightly related to cognition; however, the causal association between them remains a matter of debate. Our investigation aims to establish the causal relationship and direction between insulin resistance and cognition, while also quantifying the mediating role of brain cortical structure in this association.MethodsThe publicly available data sources for insulin resistance (fasting insulin, homeostasis model assessment beta-cell function and homeostasis model assessment insulin resistance, proinsulin), brain cortical structure, and cognitive phenotypes (visual memory, reaction time) were obtained from the MAGIC, ENIGMA, and UK Biobank datasets, respectively. We first conducted a bidirectional two-sample Mendelian randomization (MR) analysis to examine the susceptibility of insulin resistance on cognitive phenotypes. Additionally, we applied a two-step MR to assess the mediating role of cortical surficial area and thickness in the pathway from insulin resistance to cognitive impairment. The primary Inverse-variance weighted, accompanied by robust sensitivity analysis, was implemented to explore and verify our findings. The reverse MR analysis was also performed to evaluate the causal effect of cognition on insulin resistance and brain cortical structure.ResultsThis study identified genetically determined elevated level of proinsulin increased reaction time (beta=0.03, 95% confidence interval [95%CI]=0.01 to 0.05, p=0.005), while decreasing the surface area of rostral middle frontal (beta=-49.28, 95%CI=-86.30 to -12.27, p=0.009). The surface area of the rostral middle frontal mediated 20.97% (95%CI=1.44% to 40.49%) of the total effect of proinsulin on reaction time. No evidence of heterogeneity, pleiotropy, or reverse causality was observed.ConclusionsBriefly, our study noticed that elevated level of insulin resistance adversely affected cognition, with a partial mediation effect through alterations in brain cortical structure.

Geroscience in heart failure: the search for therapeutic targets in the shared pathobiology of human aging and heart failure

Age is a major risk factor for heart failure, but one that has been historically viewed as non-modifiable. Emerging evidence suggests that the biology of aging is malleable, and can potentially be intervened upon to treat age-associated chronic diseases, such as heart failure. While aging biology represents a new frontier for therapeutic target discovery in heart failure, the challenges of translating Geroscience research to the clinic are multifold. In this review, we propose a strategy that prioritizes initial target discovery in human biology. We review the rationale for starting with human omics, which has generated important insights into the shared (patho)biology of human aging and heart failure. We then discuss how this knowledge can be leveraged to identify the mechanisms of aging biology most relevant to heart failure. Lastly, we provide examples of how this human-first Geroscience approach, when paired with rigorous functional assessments in preclinical models, is leading to early-stage clinical development of gerotherapeutic approaches for heart failure.

Advances in Cardiovascular Multimodality Imaging in Patients with Marfan Syndrome

Marfan syndrome (MFS) is a genetic disorder affecting connective tissue, often leading to cardiovascular complications such as aortic aneurysms and mitral valve prolapse. Cardiovascular multimodality imaging plays a crucial role in the diagnosis, monitoring, and management of MFS patients. This review explores the advancements in echocardiography, cardiovascular magnetic resonance (CMR), cardiac computed tomography (CCT), and nuclear medicine techniques in MFS. Echocardiography remains the first-line tool, essential for assessing aortic root, mitral valve abnormalities, and cardiac function. CMR provides detailed anatomical and functional assessments without radiation exposure, making it ideal for long-term follow-up. CT offers high-resolution imaging of the aorta, crucial for surgical planning, despite its ionizing radiation. Emerging nuclear medicine techniques, though less common, show promise in evaluating myocardial involvement and inflammatory conditions. This review underscores the importance of a comprehensive imaging approach to improve outcomes and guide interventions in MFS patients. It also introduces novel aspects of multimodality approaches, emphasizing their impact on early detection and management of cardiovascular complications in MFS.

Relationship Between Intraocular Pressure and the True Rate of Functional and Structural Progression in the United Kingdom Glaucoma Treatment Study.

To investigate the effect of average intraocular pressure (IOP) on the true rate of glaucoma progression (RoP) in the United Kingdom Glaucoma Treatment Study (UKGTS). UKGTS participants were randomized to placebo or Latanoprost drops and monitored for up to two years with visual field tests (VF, 24-2 SITA standard), IOP measurements, and optic nerve imaging. We included eyes with at least three structural or functional assessments (VF with <15% false-positive errors). Structural tests measured rim area (RA) with Heidelberg retina tomography (HRT) and average peripapillary retinal nerve fiber layer (pRNFL) thickness with optical coherence tomography (OCT). One eye of 436 patients (222 on Latanoprost) was analyzed. A Bayesian hierarchical model estimated the true RoP of VF and structural metrics, and their correlations, using sign-reversed multivariable exponential distribution. RA and pRNFL measurements were converted to a dB scale, matching the VF metric (mean deviation [MD]). The effect of average IOP on the true RoPs was estimated. True RoP at the mean average IOP (17 mm Hg) was faster (P < 0.001) for VF-MD (-0.59 [-0.73, -0.48] dB/year) than HRT-RA (-0.05 [-0.07, -0.03] dB/year) and OCT-pRNFL (-0.08 [-0.11, -0.06] dB/year). The proportional acceleration of RoP per mm Hg increase was, however, not significantly different (smallest P = 0.15). Accounting for the structural floor-effect largely eliminated the differences in RoPs (smallest P = 0.25). VF appeared to deteriorate at a faster rate than structural measurements. However, this could be explained by the floor-effect from nonfunctional tissue. IOP induced a similar acceleration in RoP per mm Hg increase.

Assessment of Cognitive Functions in Multimorbid Patients in Lithuanian Primary Care Settings: A Cross-Sectional Study Using MMSE and LT-GPCOG

Background and Objectives: The aging population has led to a rise in cognitive impairments, including dementia, often associated with multimorbidity. Early diagnosis of cognitive decline is crucial, especially in primary care, where time constraints and the limitations of diagnostic tools may hinder accurate detection. This study aims to assess the cognitive functions of multimorbid patients using the Mini-Mental State Examination (MMSE) and the Lithuanian version of the General Practitioner Assessment of Cognition (LT-GPCOG). We hypothesized that the LT-GPCOG would perform similarly to the MMSE in suspecting cognitive impairments. Materials and Methods: This cross-sectional study, conducted from 2021 to 2022, included 796 patients aged 40–85, with arterial hypertension and at least one other chronic disease, recruited from seven Lithuanian primary health care centers. Cognitive function was assessed using the MMSE and LT-GPCOG, and statistical analyses were performed using SPSS to determine the association between cognitive impairment and various demographic and clinical variables. Results: Out of 796 participants, 793 completed the study. Cognitive impairment was suspected in 5.1% of participants based on MMSE and 4.2% based on the LT-GPCOG. Statistically significant associations were found between cognitive impairment and chronic obstructive pulmonary disease (COPD) (p = 0.008 and p = 0.003) in both tests and chronic kidney disease (CKD) (p = 0.005) while testing with the MMSE. Lower education and unemployment were also correlated with cognitive impairment (p = 0.008 and p &lt; 0.001). Conclusions: The findings suggest that regular cognitive assessments should be integrated into the management of multimorbid patients, particularly those with COPD and CKD. The LT-GPCOG proved to be an efficient alternative to the MMSE in primary care settings, demonstrating comparable diagnostic accuracy. Further studies are also needed to assess the sensitivity and specificity of the LT-GPCOG test.

Harmonizing Brain Function

As brain diseases become more prevalent, early assessment of brain function is increasingly vital. This study introduces a piano sight-reading data collection and processing system, along with a quantitative evaluation method for brain health based on spatiotemporal dimensions. The system demonstrated effective data storage and analysis, with speed and ability scores improving over time. At the highest difficulty (D), the right hand outperformed the left in both speed (7% advantage) and ability (8.6% higher score). Over time, Speed scores peaked at 90 for the left hand and 73 for the right, while ability scores reached 96 and 92, respectively. The method showed high sensitivity (92%) and specificity (90%), with positive and negative predictive values of 90.2% and 91.8%, confirming its reliability for detecting cognitive improvement and decline. These findings highlight the potential of musical training for early cognitive assessment and brain health promotion.

Distribution of spinal damage in patients with axial spondyloarthritis as assessed by MRI: a prospective and blinded study

BackgroundAxial spondyloarthritis (SpA) leads to structural bone lesions in every part of the vertebral column. These lesions are only partially visualized on conventional radiographs, omitting posterior parts of the vertebral column and the thoracic spine, that may nevertheless contribute to impaired spinal mobility and function in patients with axial SpA.MethodsIn this prospective and blinded investigation, we assessed the distribution of structural spinal lesions using magnetic resonance imaging (MRI) of the whole spine in 55 patients with axial SpA classified according to the Assessment in Spondyloarthritis International Society (ASAS) criteria. After assessment of spinal mobility and function two blinded radiologists independently evaluated MRIs of 23 vertebral units in every patient. Non-parametric statistical methods, Spearman‘s correlation and linear regression models were used to analyze structural lesion distribution and the relationship with clinical spinal mobility and function parameters.ResultsIn 55 patients with axial SpA (13 females, average disease duration 14.9 years) 657 ventral and 139 dorsal vertebral body structural bone lesions and, notably, 534 facet joint lesions could be visualized. The median number of lesions per patient was higher in the thoracic (8.5, range 1.0–41.0) than in the lumbar (7.5, range 0.0-27.5) and the cervical spine (3.5, range 0.0-24.5). A negative correlation was noted between the number of osteoproliferative structural bone lesions and impairment of spinal mobility and function in univariate, but not in multivariate analyses.ConclusionMRI of the whole spine revealed a high prevalence of lesions in dorsal parts of the vertebral column and in the thoracic spine in patients with axial SpA that may not be adequately visualized on conventional radiographs. These findings could further contribute to a better understanding of reduced mobility of the spine typically associated with axial SpA and assist diagnostics.

Diffusion Tensor Imaging as Neurologic Predictor in Patients Affected by Traumatic Brain Injury: Scoping Review

Background: Diffusion tensor imaging (DTI), a variant of Diffusion Weighted Imaging (DWI), enables a neuroanatomical microscopic-like examination of the brain, which can detect brain damage using physical parameters. DTI’s application to traumatic brain injury (TBI) has the potential to reveal radiological features that can assist in predicting the clinical outcomes of these patients. What is the ongoing role of DTI in detecting brain alterations and predicting neurological outcomes in patients with moderate to severe traumatic brain injury and/or diffuse axonal injury? Methods: A scoping review of the PubMed, Scopus, EMBASE, and Cochrane databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The aim was to identify all potentially relevant studies concerning the role of DTI in TBI. From an initial pool of 3527 publications, 26 articles were selected based on relevance. These studies included a total of 729 patients with moderate to severe TBI and/or diffuse axonal injury. DTI parameters were analyzed to determine their relationship with neurological outcomes post-TBI, with assessments of several brain functions and regions. Results: The studies included various DTI parameters, identifying significant relationships between DTI variations and neurological outcomes following TBI. Multiple brain functions and regions were evaluated, demonstrating the capability of DTI to detect brain alterations with higher accuracy, sensitivity, and specificity than MRI alone. Conclusions: DTI is a valuable tool for detecting brain alterations in TBI patients, offering enhanced accuracy, sensitivity, and specificity compared to MRI alone. Recent studies confirm its effectiveness in identifying neurological impairments and predicting outcomes in patients following brain trauma, underscoring its utility in clinical settings for managing TBI.

TRADUÇÃO, ADAPTAÇÃO TRANSCULTURAL E VALIDAÇÃO DA ESCALA SANE PARA PACIENTES SUBMETIDOS À ARTROPLASTIA TOTAL DE JOELHO

This study conducted the translation, cross-cultural adaptation, and validation of the Single Assessment Numeric Evaluation (SANE) Scale into Brazilian Portuguese, aimed at assessing the functionality of patients undergoing Total Knee Arthroplasty (TKA). The process included translation, back-translation, expert committee review, and semantic validation with patients, following rigorous methodological guidelines. The adapted version of the SANE proved to be understandable, culturally relevant, and appropriate for the Brazilian population, facilitating the accurate collection of data on functional recovery. Psychometric analyses demonstrated high reliability (Cronbach’s alpha &gt; 0.70) and excellent reproducibility (ICC &gt; 0.75). Construct validity was confirmed through significant correlations with established measures such as the KOOS and IKDC. The SANE Scale has shown to be an effective tool for quick and objective assessment, standing out for its practicality in clinical settings. The study concludes that SANE is a valid and reliable alternative for orthopedic practice, with the potential to simplify functional assessment in post-TKA patients.

Comparing achievability and reproducibility of pulsed wave doppler and tissue doppler myocardial performance index and spatiotemporal image correlation annular plane systolic excursion in the cardiac function assessment of normal pregnancies.

Multiple techniques have been proposed for functional fetal cardiology, including pulsed-wave (PW) and tissue Doppler imaging (TDI), Myocardial Performance Index (MPI), annular plane systolic excursion (TAPSE/MAPSE) and spatiotemporal image correlation (STIC). We aimed to compare these techniques' achievability and reproducibility to determine their clinical utility for each cardiac side. Uncomplicated pregnancies from 22 to 39weeks were recruited and images and volumes stored for offline analysis. PWD-MPI values were calculated using previously demonstrated automation algorithms, and the remaining volumes were evaluated by two experienced operators. 79 women were scanned generating 222 volumes, with high achievability (>86 %) for all three modalities on both cardiac sides; highest for TAPSE/MAPSE (94 %). Repeatability (ICC) on the right side of the heart was highest for TAPSE (inter-observer 0.86; intraobserver 0.73), compared to PWD-MPI (0.69) and TDI-MPI (0.83). For the left side, repeatability was high for both PWD-MPI (0.80) and TDI-MPI (0.86) though low for MAPSE (inter-observer 0.7, intra-observer 0.69). There was poor correlation between PWD-MPI and TDI-MPI values. TAPSE appears most reliable for evaluation of right heart function, compared to PWD-MPI for the left. As TDI-MPI correlates poorly with PWD-MPI, the latter appears to be the functional tool of choice.

Radiomics and dosiomics approaches to estimate lung function after stereotactic body radiation therapy in patients with lung tumors.

Lung function assessment is essential for determining the optimal treatment strategy for radiation therapy in patients with lung tumors. This study aimed to develop radiomics and dosiomics approaches to estimate pulmonary function test (PFT) results in post-stereotactic body radiation therapy (SBRT). Sixty-four patients with lung tumors who underwent SBRT were included. Models were created to estimate the PFT results at 0-6months (Cohort 1) and 6-24months (Cohort 2) after SBRT. Radiomics and dosiomics features were extracted from the computed tomography (CT) images and dose distributions, respectively. To estimate the PFT results, Models A (dose-volume histogram [DVH] + radiomics features) and B (DVH + radiomics + dosiomics features) were created. In the PFT results, the forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) were estimated using each model, and the ratio of FEV1 to FVC (FEV1/FVC) was calculated. The Pearson's correlation coefficient (Pearson r) and area under the curve (AUC) for FEV1/FVC (< 70%) were calculated. The models were evaluated by comparing them with the conventional calculation formulae (Conventional). The Pearson r (FEV1/FVC) values were 0.30, 0.64, and 0.69 for Conventional and Models A and B (Cohort 2), respectively, and the AUC (FEV1/FVC < 70%) values were 0.63, 0.80, and 0.78, respectively. This study demonstrates the possibility of estimating lung function after SBRT using radiomics and dosiomics features based on planning CT images and dose distributions.

Diagnostic modalities for ischemic heart disease: evaluating the role of stress echocardiography, cardiac CT, and myocardial perfusion scintigraphy in guiding coronary angiography

Cardiovascular diseases, particularly ischemic heart disease (IHD), are the leading cause of mortality globally, accounting for 16% of deaths. Effective management of ischemic cardiomyopathy (ICM) is crucial, as outlined in the latest European Society of Cardiology (ESC) guidelines for chronic coronary syndrome (CCS). The guidelines emphasize a structured approach comprising four key steps: a general clinical evaluation to exclude non-cardiac causes, cardiac examination, and likelihood estimation using echocardiography, diagnostic testing such as stress echocardiography and coronary CT angiography, and treatment involving lifestyle changes and medication, alongside potential revascularization. The review underscores the importance of coronary angiography and functional assessments in diagnosing ischemic heart failure (IHF) and guiding treatment strategies. Non-invasive imaging techniques, including stress echocardiography and myocardial perfusion scintigraphy, are valuable for assessing ischemia and myocardial viability while reducing unnecessary invasive procedures. Coronary CT angiography is also examined for its procedural advantages and risks. A comparative analysis of diagnostic modalities highlights the strengths and limitations of each technique, emphasizing the need for individualized approaches based on patient characteristics. The ESC 2024 guidelines advocate for a patient-centered imaging strategy based on the likelihood of coronary artery disease (CAD) while addressing the economic and environmental impacts of imaging practices. Overall, implementing these guidelines and leveraging diverse imaging modalities can optimize management strategies for IHD, ultimately improving patient outcomes.

Assessment of DFT Functionals for Structural Determination of Lanthanide(III) Complexes Using Ligand Field Splitting.

Lanthanide (Ln3+) tetrakis complexes, C[Ln(L)4], are important for applications due to their high quantum yields, solubility, and stability. Their luminescent properties depend on the structure, particularly the coordination polyhedron, the assessment of computational methods for calculating their structures is paramount. Usually, this assessment uses the RMSD of distances in the [Ln(L)4]- complex or {LnO8} polyhedron between crystallographic and calculated structures. However, since ligand field (LF) splitting is highly geometry-dependent, the RMSD between experimental LF splitting and Stark levels (RMSD-LF) offers a more accurate measure for evaluating quantum methods. LF energy eigenvalues were calculated using the simple overlap model (SOM), with geometries optimized by various density functionals. M06 and M06-L functionals, with def2-SVP/MWB52(Eu)/CPCM, demonstrate the best balance in best accuracy and low computational cost, making them suitable for modeling C[Eu(L)4] complexes.

A hypocaloric protein-rich diet before metabolic surgery improves liver function in patients with obesity and diabetes

PurposeObesity and type 2 diabetes (T2DM) are major risk factors for hepatic steatosis. Diet or bariatric surgery can reduce liver volume, fat content, and inflammation. However, little is known about their effects on liver function, as evaluated here using the LiMAx test.MethodsIn the MetaSurg study (RCT on the effects of different Roux-en-Y gastric bypass (RYGB) limb lengths on diabetes remission in patients with BMI ≥ 27 to ≤ 60 kg/m2 and T2DM; trial registration: DRKS00007810, German Clinical Trials Register Freiburg), 24 consecutive patients underwent liver function (LiMAx) and imaging assessments (MRI, transient elastography; TE) before and after diet and surgery. Two weeks before surgery, the patients received a hypocaloric protein-rich diet.ResultsNine of 18 patients had a pathologic LiMAx value (≤ 315 µg/kg/h) at baseline. After two weeks of diet, LiMAx values improved (p = 0.01, paired t test, n = 15). LiMAx values further recovered six months after RYGB (p = 0.01, paired t test, n = 15), which was accompanied by decreased liver volumes (p = 0.005, paired t test, n = 10), proton density fat fraction (p = 0.003, paired t test, n = 12), and TE measurements (p = 0.032, paired t test, n = 14). The need for medical diabetes treatment decreased from 100 to 35%.ConclusionLiver function improved after a two-week hypocaloric protein-rich diet and metabolic surgery in patients with obesity and T2DM. These data suggest that a two-week diet for this group of patients prior to abdominal surgery could improve a presumably impaired liver function.

Androgen Receptor Pathway Inhibitor Therapy for Advanced Prostate Cancer: Secondary Analysis of a Randomized Clinical Trial.

The open-label randomized phase 2 LACOG0415 trial evaluated 3 treatment strategies for patients with advanced castration-sensitive prostate cancer (CSPC): androgen deprivation therapy (ADT) plus abiraterone acetate and prednisone (AAP), apalutamide (APA) alone, or APA plus AAP. To investigate the association of ADT plus AAP, APA alone, or APA plus AAP with health-related quality of life (HRQOL) in patients with advanced CSPC in the LACOG0415 trial. The LACOG0415 randomized clinical trial comprised 128 patients with advanced CSPC who were randomized (1:1:1) to 1 of 3 treatment arms from October 16, 2017, to April 23, 2019. Statistical analysis was conducted from March to September 2022. Patients were randomized (1:1:1) to 1 of 3 treatment arms: ADT plus AAP, APA alone, or APA plus AAP. Health-related quality of life was evaluated using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) questionnaire, including its subscales, completed at baseline and every 4 weeks until week 25. FACT-P scores range from 0 to 156, and higher scores indicate better HRQOL. Mean changes in score from baseline to week 25 were adjusted by baseline score and were calculated to evaluate whether there was a difference according to the treatment arm using a mixed-effect model for repeated measures. Time to deterioration was estimated by Kaplan-Meier curves and compared by stratified log-rank test. Analysis was performed on an intention-to-treat basis. A total of 128 patients with advanced CSPC were randomized to receive ADT plus AAP (n = 42; median age, 69.8 years [IQR, 58.9-71.6 years]), APA alone (n = 42; median age, 69.5 years [IQR, 59.8-72.6 years]), or APA plus AAP (n = 44; median age, 71.0 years [IQR, 63.0-72.3 years]). Metastatic disease was present in 95 patients (74.2%), high-risk biochemical recurrence disease in 22 (17.2%), and locally advanced disease in 11 (8.6%). There was no significant difference in baseline mean (SD) FACT-P total scores and subscales among the 3 treatment arms (FACT-P total score: ADT plus AAP arm, 118.5 [24.3]; APA alone arm, 116.1 [23.9]; AAP plus APA arm, 114.9 [18.1]; P = .69). Health-related quality of life was maintained during treatment period, and there were no statistically significant differences at 25 weeks in mean (SD) FACT-P total scores or subscales between treatment arms (FACT-P total score: ADT plus AAP arm, 122.3 [20.4]; APA alone arm, 119.5 [16.4]; AAP plus APA arm, 119.9 [20.3]). The APA alone and AAP plus APA arms were not associated with meaningful improvements in HRQOL compared with the ADT plus AAP arm, except in time to deterioration of the emotional well-being score, which was more favorable in the APA alone arm (reference arm: ADT plus AAP arm; APA alone arm: hazard ratio, 0.37 [0.15-0.85]; P = .02; ADT plus AAP arm: hazard ratio, 0.56 [0.26-1.19]; P = .13). Limitations include short follow-up period and the absence of other questionnaires to capture differences between therapies. In this prespecified secondary analysis of a randomized clinical trial of ADT plus AAP, APA alone, or APA plus AAP for patients with advanced CSPC, HRQOL was not statistically different between treatments with APA alone or APA plus AAP as compared with ADT plus AAP. Larger studies with longer follow-up and more specific questionnaires are needed to further evaluate HRQOL with these treatment strategies. ClinicalTrials.gov Identifier: NCT02867020.
