Implementing a multidisciplinary approach for older adults with multiple sclerosis: Geriatric neurology in practice

BackgroundOlder adults with multiple sclerosis (MS) face unique challenges arising from age-related changes in MS pathophysiology and overlapping geriatric syndromes. There is a need for geriatrics-focused multidisciplinary care for the rapidly growing older MS population. ObjectiveTo design and implement a geriatric multidisciplinary clinic for older adults with MS. MethodsWe describe the development of a multidisciplinary approach to geriatric MS care within a single institution through the implementation of the Aging with MS Clinic. The clinic model was conceived through collaboration between neurology and geriatric medicine to provide comprehensive care for older adults with MS who are uniquely affected by overlapping symptoms of aging and MS (e.g., frailty, falls, functional decline, multiple comorbidities, polypharmacy, cognitive impairment, nutritional deficits, barriers to access healthcare). Multidisciplinary specialists were recruited to staff the clinic, and initial patient satisfaction outcomes were collected. ResultsThe team of multidisciplinary specialists staffing the clinic consists of a MS advanced practice practitioner, MS pharmacist, physical therapist, neuropsychologist, dietitian, and social worker. A clinic template was devised where 4 patients with MS over age 60 are seen by each specialist during each half-day clinic session. Initial patient satisfaction surveys from 25 participants showed overwhelmingly positive feedback. A majority of participants (92%) agreed that the clinic was well-organized, while 92% felt they benefitted from attending. Additionally, 80% of participants reported that the clinic improved their overall quality of care. ConclusionThe Aging with MS clinic outlines a model for comprehensive geriatric assessment and care in older adults with MS by a team of multidisciplinary specialists. Initial feedback from patients who attended the clinic conveyed improved quality of care.

Exploring educational ecosystems: insights from the implementation of SchoolWeavers tool in Catalonia

ABSTRACT Education has undergone significant changes, leading to more complex and collaborative approaches that recognize schools as ecosystems where diverse stakeholders interact. Consequently, new processes and tools are needed to promote leadership within these ecosystems. To guide school leadership teams, we developed and piloted the online tool ‘SchoolWeavers’, which fosters relationships and collaboration across the ecosystem to improve learning and well-being. This study examines the initial outcomes of using SchoolWeavers as a school leadership strategy in five schools in Catalonia, Spain, by surveying 1,615 members of the ecosystem, including teachers, leaders, staff, families, students, and community professionals. The aim is to investigate school ecosystem dynamics through the domains addressed by the tool, such as empathy, trust, shared purpose, innovation, collaboration, equity, and personalized learning, identifying opportunities for improvement and ways to foster stronger educational ecosystems. Leadership teams showed the highest scores and positive perceptions, while students rated the domains lower. Community professionals had low participation, indicating weaker collaboration with the community. Trust and equity received the highest scores, whereas innovation and personalized learning were less valued. This study highlights the need for tools to strengthen educational ecosystems and identifies areas for improvement, particularly in innovation and student agency.

Relationship between big five personality and health literacy in elderly patients with chronic diseases: the mediating roles of family communication and self-efficacy

The significance of health literacy for elderly individuals with chronic illnesses lies in managing and delaying disease development, which is affected by personal and environmental factors. Family communication can provide an emotional support environment; self-efficacy is an important factor of subjective initiative and personality. A relatively persistent thinking and behavior pattern can affect the environment, subjective initiative, and individual health outcomes. This study aims to explore the effects of the Big Five personality traits on the health literacy of elderly individuals with chronic illnesses and to hypothesize that family communication and self-efficacy mediate the Big Five personalities and health literacy. A cross-sectional study of 2251 elderly individuals with chronic diseases was conducted through nationwide random quota sampling. The structural equation model was used to explore the mediating role of family communication and self-efficacy between the Big Five personality and health literacy. Family communication played a simple mediating role in the influence of extraversion, agreeableness, conscientiousness, and neuroticism on health literacy. Self-efficacy played a simple mediating role in the influence of the Big Five personalities on health literacy. Self-efficacy and family communication played a chain mediating role between extraversion, agreeableness, conscientiousness, neuroticism, and health literacy. Nurses can enhance the health literacy of elderly individuals with chronic illnesses with extraversion, agreeableness, conscientiousness, and neuroticism through family communication and self-efficacy while promoting the health literacy of those with openness through self-efficacy.

Experimenting with a strong dual necessity approach to social progress

Different social progress indices assess well-being and development differently and thus reflect distinct conceptions of social progress. Broadly, these conceptions fall into two categories: ‘subjective’—the attitudes of individuals; and ‘objective’—external standards. Our starting point is a strong ‘dual necessity’ claim, namely that the two categories of conception have joint-special significance. Such a strong dual necessity conception, when operationalized, demands very low compensability/degree of substitution between the two independent indices, objective and subjective. Experimenting with this idea, we hypothesize that implementing low substitution empirically influences outcomes. Previous research presented this concept and exemplified initial empirical outcomes. The present work enhances and broadens this research by employing the constant elasticity of substitution (CES) function, which allows for the adjustment of substitution levels and comparison of resulting rankings. Furthermore, we demonstrate the results using two different well-known and commonly used indices: Human Development Index (HDI) and Sustainable Development Goals Index (SDGI). Our findings show that using a low substitution approach alters the social progress rankings of many countries in comparison to the original components’ rankings and to a high substitution combination of the two. This holds particularly true for countries in the middle of the original rankings. The paper’s original contribution is that it establishes the CES function as a useful device for implementing the idea of ‘dual necessity.’ Importantly, by experimenting with low substitution, and exemplifying its empirical significance with the CES function, the paper also contributes to further validating a strong dual necessity conception and justifies its own measurement. Such measurement should be of value to social scientists, practitioners and policymakers who care for balanced social progress: social progress that does not neglect either of the two aspects (subjective or objective).

Association of initial serum sodium change and clinical outcome in patients with diabetes receiving sodium-glucose cotransporter-2 inhibitor therapy: A multicentre database analysis in Taiwan.

The study aimed to assess the impact of varying degrees of initial serum sodium change among patients with type 2 diabetes (T2D) starting sodium-glucose cotransporter-2 inhibitor (SGLT2i) therapy and their subsequent clinical outcome. We used medical data from a multicentre health care provider in Taiwan and recruited 4400 patients with T2D with baseline normal serum sodium (135-145 mmol/L) and follow-up serum sodium measures available after 3 months of SGLT2i treatment from 1 June 2016 to 31 December 2021. After a median of 2.9 (2.4, 3.4) months of SGLT2i treatment, overall, there was a minimal change in serum sodium levels (from 139.6 ± 2.4 to 139.5 ± 3.7 mmol/L). Most patients (87.8%) maintained normal sodium levels, while 8.6% (n = 378) experienced hyponatraemia (<135 mmol/L) and 3.6% (n = 158) hypernatraemia (>145 mmol/L). Factors independently associated with hyponatraemia included cancer history, chronic lung disease, insulin use, higher glycated haemoglobin, impaired liver function, lower baseline sodium and greater initial decline in kidney function. Conversely, factors linked to hypernatraemia included older age, absence of cancer history, loop diuretic and non-steroidal anti-inflammatory drug use, higher baseline sodium and a lesser initial decline in kidney function. Over a median of 26.0 months of follow-up, hyponatraemia shortly after starting SGLT2i therapy was associated with significantly increased risks of major adverse cardiovascular events [hazard ratio (HR): 2.52; 95% confidence interval (CI): 1.83-3.48], heart failure for hospitalization (HR: 1.66; 95% CI: 1.16-2.37), major adverse renal events (HR: 2.27; 95% CI: 1.73-2.96) and all-cause death (HR: 2.98; 95% CI: 2.17-4.11) after adjusting for clinically relevant factors. Non-linear analysis indicated that a more pronounced initial decline in serum sodium levels correlated steeply with higher risks of these adverse events. While most patients with T2D maintain stable serum sodium homeostasis on SGLT2i therapy, a subset may experience dysnatraemic events with potential worse clinical consequences. Physicians should be vigilant about monitoring sodium levels and considering the associated risks when initiating SGLT2i therapy in patients with risk.

STAT1 and STAT3 gain of function: clinically heterogenous immune regulatory disorders.

The identification of STAT1 gain-of-function (GOF) in 2011 and STAT3 GOF in 2014 has advanced our understanding of the host immunity along the JAK/STAT pathway and allowed targeted treatment approaches. We review the clinical features and pathogenesis of STAT1 and STAT3 GOF and how this has shaped new approaches to therapy. STAT1 GOF, initially described in patients with chronic mucocutaneous candidiasis (CMC) and autoimmune thyroid disease, is now recognized to cause early-onset multisystem autoimmunity and a range of infections. STAT3 GOF comprises mostly lymphoproliferation and autoimmunity but also with varying severity, including some with life threatening organ dysfunction. Treatment has evolved along with the understanding of the pathogenesis, with patients now receiving JAK inhibition to block upstream of the STAT defect with good response in autoimmunity and CMC in STAT1 GOF. Blockade of IL-6 signaling has also been used in STAT3 GOF. Hematopoietic cell transplantation had initial poor outcomes, but outcomes are now improving with focus on the control of inflammation pretransplant. Understanding the pathogenesis of STAT1 and STAT3 GOF has allowed great recent advancements in therapy, but many questions remain as to the best approach to therapy for each patient's clinical presentation as well as the durability of these therapies.

Beyond success and failure: learning from execution of corporate entrepreneurial actions

Building locally anchored implementation science capacity: the case of the adolescent HIV implementation science alliance-supported local iS alliances.

The Fogarty International Center-led Adolescent HIV Implementation Science Alliance (AHISA) supports region-/country-specific implementation science (IS) alliances that build collaborations between research, policy, and program partners that respond to local implementation challenges. AHISA supported the development of seven locally-led IS alliances: five country-specific (i.e., Kenya, South Africa, Tanzania, Uganda, and Zambia), one in Central and West Africa, and one with youth researchers. This article outlines the aims, activities, and outcomes of local alliances, demonstrating how they enhance sustainable IS activities to address local challenges. We conducted a desk review of each alliance's funding applications, reports, and data from the initial findings of a larger AHISA evaluation. The review analyzes common approaches, highlights their local relevance, and summarizes initial outcomes. The local alliances have a common goal: to expand implementation of successful interventions to improve adolescent HIV. We identified four overarching themes across the local alliances' activities: capacity building, priority setting, stakeholder engagement, and knowledge dissemination. Research capacity building activities include long-term mentorship between junior and senior researchers and short-term training for non-research partners. Setting priorities with members identifies local research needs and streamlines activities. Alliances incorporate substantial engagement between partners, particularly youth, who may serve as leaders and co-create activities. Dissemination shares activities and results broadly. Local IS alliances play a key role in building sustainable IS learning and collaboration platforms, enabling improved uptake of evidence into policy and programs, increased IS research capacity, and shared approaches to addressing implementation challenges.

The Significance of an Initial Controlling Nutritional Status Score in Predicting the Functional Outcome, Complications, and Mortality in a First-Ever Ischemic Stroke

Background and Purpose: Nutritional status can influence the outcomes and mortality of various diseases. The association between initial nutritional status and ischemic stroke outcomes, however, remains poorly understood. This study investigated whether the Controlling Nutritional Status (CONUT) score at admission could predict functional recovery, complications, and survival following an ischemic stroke. Methods: We enrolled a total of 938 patients experiencing their first acute ischemic stroke and categorized them into three groups based on their CONUT score at admission: CONUT 0–1, CONUT 2–4, and CONUT 5–12. The CONUT score was assessed using the serum albumin, total cholesterol, and lymphocyte count. We evaluated the incidence of complications during their hospital stay. Outcomes, including the Modified Rankin Scale (mRS), Functional Independence Measurement (FIM), Functional Ambulatory Classification (FAC), and mortality, were assessed at baseline, as well as at three and six months post-stroke. Results: CONUT scores were significantly associated with functional outcomes (mRS, FIM, and FAC) and mortality during the six-month follow-up period post-stroke (all p &lt; 0.05). The CONUT 5–12 group exhibited significantly poorer improvements in mRS, FIM, and FAC scores (all p &lt; 0.05) and a lower survival rate (p &lt; 0.01) during the six-month follow-up compared to the CONUT 0–1 and CONUT 2–4 groups. Additionally, the incidence of pneumonia, urinary tract infections, pressure sores, falling injuries, and fractures was significantly higher in the CONUT 5–12 group than in the other groups (all p &lt; 0.01). Conclusions: CONUT scores at admission are associated with functional recovery, mortality, and the incidence of complications following a first-ever ischemic stroke. Consequently, the early identification of patients at risk of malnutrition via CONUT scores can be crucial in enhancing patient assessment after an acute stroke.

Fathers' engagement in a parenting program primarily intended for female caregivers: An early qualitative process evaluation in Western Kenya.

Parenting programs predominantly target one caregiver of the child or most commonly the child's mother. However, fathers are also important caregivers whose engagement in interventions can benefit child health, nutrition, and development. In August 2023, a qualitative process evaluation was conducted during the first quarter of implementation to assess initial fidelity, quality, and outcomes of a parenting program in rural Western Kenya. In-depth interviews were conducted with female and male caregivers along with in-depth interviews and focus group discussions with program delivery agents. This secondary analysis specifically focused on stakeholders' perceptions of father involvement in the program and aimed to identify barriers and facilitators to fathers' participation, initial program impacts when fathers were involved, and recommendations for increasing father inclusion. Thematic content analysis was conducted, and data were triangulated across stakeholder groups. Overall, relatively few fathers participated in the program. Nevertheless, for the rare cases of participating fathers, stakeholders highlighted positive changes in fathers' caregiving attitudes and practices. Key barriers to fathers' program engagement included restrictive gender norms and perceived opportunity costs. Stakeholders suggested several strategies for better reaching fathers, including providing financial incentives and flexible scheduling of sessions. Overall, we found that fathers' participation and program experiences were starkly different from those of mothers. Gender-responsive program adaptations and father-targeted implementation strategies are likely to increase the fathers' engagement in parenting programs, which in turn may facilitate greater program impacts on family caregiving and child outcomes. Future evaluations of parenting programs should combine qualitative and quantitative approaches to more comprehensively assess program impacts on fathers and over time.

Association between initial antibiotic route and outcomes for children hospitalized with pneumonia.

Initial oral antibiotics may be as effective as intravenous (IV) antibiotics for children hospitalized with community-acquired pneumonia (CAP), but further data are needed. We evaluated for associations of initial antibiotic route (IV vs. oral) with length of stay (LOS) and secondary outcomes for children hospitalized with CAP. This multicenter, retrospective cohort study included children with CAP who were hospitalized for >48 h, had chest radiographs, and received antibiotics at four children's hospitals between 2014 and 2020. Data were obtained from the Pediatric Health Information System and manual chart review. The exposure was initial antibiotic route (i.e., first antibiotic given intravenously or orally). We performed multivariable regression modeling using inverse probability treatment weights from propensity scores. Outcomes included LOS, oxygen duration, cost, care escalation, and readmission or emergency department revisit. Of 1147 included children, 37% received initial oral antibiotics. Within the propensity balanced sample, LOS was 73.5 h (IQR 61.0, 99.5) and 78.7 (61.0, 118.0) for patients with initial oral and IV antibiotics, respectively. Children receiving initial oral antibiotics had an 8% reduction in LOS (OR 0.92 [95% CI: 0.87, 0.94]) and 14% reduction in cost (OR 0.86 [95% CI 0.79, 0.94]) versus those receiving initial IV antibiotics. There were no differences in other outcomes. Children with CAP receiving initial oral antibiotics had reduced LOS and hospital cost without differences in escalated care or return visits. Starting hospitalized children on oral antibiotics is likely a safe and effective alternative to IV treatment.

Geometry of Modern Presbyopia-Correcting Intraocular Lenses and Changes in Haptic-Capsular Bag Behavior According to Compression and Different Well Diameters: A Bench Study Using Computed Tomography.

The geometry of an intraocular lens(IOL), the design of the haptics, and the optic-haptic junction play a role in initial and long-term visual outcome after cataract surgery. Knowledge of the behavior of an implant in the capsular bag and under compression is of major importance. Our laboratory experiment analyzed in-depth the geometry of acrylic, single-piece, premium, presbyopia-correcting intraocular lenses and changes in haptic-capsular bag relationships according to capsular bag size using a range of compression well diameters. One hydrophilic (RayOne Trifocal® RAO603F) and three hydrophobic intraocular lenses (AcrySof IQ PanOptix®, Synergy DFR00V™, and AT ELANA 841P®) were scanned with computed tomography (CT) in a dry, uncompressed state for quantitative analyses of haptic and optic-haptic junction (OHJ) dimensions and qualitative assessment of geometry. In the second part of the experiment, CT was performed after sample placement into a series of compression wells (9.0, 10.0, 11.0, 11.5mm) for analyses of length of contact (LoC) between the haptics and the wells. Axial alignment and haptic-capsular bag relationships were assessed. The qualitative and quantitative evaluations highlighted differences in haptic and OHJ geometry and dimensions across the samples. The mid-zone of the optic was thickest in the hydrophilic sample (RayOne Trifocal® RAO603F) with a maximum of 0.880mm compared to the thinnest hydrophobic sample (AT ELANA 841P®) with 0.564mm. The AT ELANA 841P® showed the largest OHJ surface area (3.86mm2) and OHJ volume (0.60mm3) of the hydrophobic samples. The TECNIS Synergy DFR00V™ showed the thickest OHJ (0.51mm), while the AcrySof IQ PanOptix® showed the thinnest OHJ (0.21mm). The LoC values decreased with increasing well size for all tested samples. The AT ELANA 841P® showed the largest LoC and largest contact zones of hydrophobic samples in all wells. The laboratory experiments highlight differences in the haptics, the OHJ geometric characteristics, and behavior of samples in different well diameters. The results support the idea that specific IOL designs may have advantages or disadvantages depending on anatomical dimensions. We cannot make any classification or rating (good versus bad) for clinical practice on the basis these experimental results, as many other factors play a role. However, knowledge of IOL geometry seems important to select the best option in each individual case.

Totally 3D endoscopic aortic valve replacement: initial results and experience from a single center.

This study aimed to evaluate the feasibility and initial outcomes of totally endoscopic aortic valve replacement (TEAVR) performed via a single working port at the fourth intercostal space (ICS) utilizing a 3D endoscopic system. A retrospective observational study was conducted on 35 consecutive patients who underwent TEAVR over a six-month period from December 2023 to June 2024. Patient selection was based on the presence of isolated aortic valve disease without the need for ascending aorta replacement or aortic root enlargement. A 4 cm single working port was created at the 4th ICS, extending from the right mid-axillary to the anterior axillary line. A 10-mm trocar for a 3D endoscope was placed at the right anterior-axillary line. Peripheral cardiopulmonary bypass (CPB) was established. The primary outcomes investigated included the success rate of the procedure, in-hospital mortality, and perioperative complications. The mean age of the patients was 58.7 ± 12.8 years, with 22.9% being female. The majority of patients (77.1%) presented with aortic stenosis, often accompanied by severe calcification. The medianCPB time was 210 ± 43 min, and the median aortic cross-clamp time was 132 ± 41 min. The procedure was successfully completed in all patients using the endoscopic approach, with no conversions to full sternotomy. Two mortalities were recorded, attributed to postoperative complications including bleeding and cerebral infarctions. The early (30-day) mortality rate was 5.7%. Prolonged mechanical ventilation (>48 h) was required in 17.1% of patients, and reoperation for bleeding was necessary in 2.9% of patients. TEAVR is a feasible procedure with the potential to replace the traditional sternotomy approach for aortic valve replacement.

A Hybrid Method Based on Haris Corner and Maximally Stable Extremal Regions for Vehicle Plate Number Detection

An intelligent transportation system (ITS) is a crucial element of a smart city, and it includes the capability to identify vehicle license plates. Utilizing digital image processing is a cost-effective method for identification. The tiny size of the number plate is just one of the many unfortunate difficulties with this approach. Hence, this research is crucial, particularly in enhancing the precision of detection. The Harris Corner approach is one way to locate the motor vehicle number plate location. However, the Harris corner method could be more optimal for analyzing moving vehicle videos as input. Since frame-by-frame variations in the video input's lighting, accuracy cannot be maximized. Furthermore, the vehicle and license plate appear significantly smaller due to the camera's distant positioning. Consequently, the authors suggest a hybrid approach using the Maximally Stable Extremal Regions (MSER) method. The Harris Corner and MSER methods will concurrently identify the initial position of the vehicle number plate. Moreover, the initial detection outcomes of the two techniques are compared and adjusted to achieve a more precise determination of the placement of the number plate. The results show that integrating the MSER method into the Harris Corner method yields a hybrid approach that enhances accuracy by 13%. Furthermore, it visually represents the selected number plate with greater accuracy.

Social skills programme for adolescents with depression: initial outcomes of a hospital based study in Sri Lanka

ObjectiveThis quasi-experimental study aimed to describe the outcome of a social skills intervention for adolescents with depression followed up at an outpatient Child and Adolescent Psychiatry Unit. Twenty adolescents with depression attending a tertiary care facility in Colombo, Sri Lanka were recruited, who participated in two social skills training programmes (6 months apart), in addition to pharmacological treatment. Outcome of the programme was measured by a self-administered questionnaire that assessed perceived changes in social skills, before and after the intervention. Wilcoxon Signed Rank test was used to determine the statistical significance of improvement in social skills.ResultsThe sample consisted of 80% (n = 16) female adolescents. Median scores (inter-quartile range) for social skills before and after the first social skills programme were 31.5 (21.0–36.0) and 33.0 (28.25–40.25) respectively, indicating a significant improvement in social skills following intervention (p = 0.011, r = 0.57). A similar improvement was observed after the second programme (n = 10), reporting higher median scores for social skills after intervention (29.5 vs. 37.5, p = 0.005, r = 0.89). A significant improvement was also observed in perceived ability to cope with depressive thoughts after intervention (p = 0.032), indicating that social skills training can be a useful adjunct to pharmacological interventions, in the management of depression in adolescents.

Comparative Safety and Efficacy of Roux-en-Y Gastric Bypass Versus One-Anastomosis Gastric Bypass: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

Obesity has become a global epidemic, affecting both developed and developing nations. Despite extensive efforts, historical outcomes of medical interventions for obesity have been unsatisfactory. Bariatric surgeries, including sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (RYGB), are now recognized as the primary treatment for severe obesity. However, laparoscopic one-anastomosis gastric bypass (OAGB) has emerged as a promising alternative, offering simplified procedures compared to RYGB. While OAGB's initial outcomes are optimistic, concerns about biliary reflux persist. Our systematic review aims to compare the safety and efficacy outcomes of RYGB and OAGB to inform clinical decision-making in managing obesity. We searched five databases up to February 2024. We included randomized controlled trials (RCTs) comparing RYGB and OAGB in obese patients, focusing on safety and efficacy outcomes. Data extraction covered study details, participant demographics, interventions, and outcomes related to operative details, complications, follow-up results, and weight changes. The risk of bias was assessed using the Cochrane tool. The analysis involved risk ratios for dichotomous data and mean differences for continuous data, using fixed or random effects models based on heterogeneity. Analyses were performed with Review Manager software v5.4. A total of 1057 patients were included in the analysis, sourced from 12 distinct RCTs. The analysis indicated OAGB outperformed RYGB in BMI reduction (MD = -0.69, p = 0.005), whereas RYGB was more effective in excess weight loss (MD = 6.51, p < 0.0001) and excess BMI loss (MD = 3.91, p < 0.0001). OAGB led to shorter operation times (MD = -34.89 minutes, p < 0.0001) and shorter periods of hospital stays (MD = -0.27 days, p = 0.01), along with fewer overall complications (RR = 0.58, p = 0.02) and lower incidence of upper gastrointestinal endoscopy complications (RR = 2.98, p = 0.0001). On the other hand, RYGB showed higher remission rates for dyslipidemia (RR = 0.60, p = 0.0003) and higher remissions of hypertension (RR = 0.83, p = 0.04). The majority of results were homogenous. Both OAGB and RYGB have their respective advantages and limitations. OAGB appears to offer benefits in terms of operation efficiency and early postoperative recovery, making it a potentially preferable option for patients and surgeons focused on these aspects. On the other hand, RYGB might be more suitable for patients prioritizing long-term weight loss and remission of certain comorbidities like hypertension. Ultimately, the choice between OAGB and RYGB should be made on an individual basis, considering the specific needs, conditions, and goals of each patient.

Tumor-associated macrophages: A sentinel of innate immune system in tumor microenvironment gone haywire.

The tumor microenvironment (TME) is a critical determinant in the initiation, progression, and treatment outcomes of various cancers. Comprising of cancer-associated fibroblasts (CAF), immune cells, blood vessels, and signaling molecules, the TME is often likened to the soil supporting the seed (tumor). Among its constituents, tumor-associated macrophages (TAMs) play a pivotal role, exhibiting a dual nature as both promoters and inhibitors of tumor growth. This review explores the intricate relationship between TAMs and the TME, emphasizing their diverse functions, from phagocytosis and tissue repair to modulating immune responses. The plasticity of TAMs is highlighted, showcasing their ability to adopt either protumorigenic or anti-tumorigenic phenotypes based on environmental cues. In the context of cancer, TAMs' pro-tumorigenic activities include promoting angiogenesis, inhibiting immune responses, and fostering metastasis. The manuscript delves into therapeutic strategies targeting TAMs, emphasizing the challenges faced in depleting or inhibiting TAMs due to their multifaceted roles. The focus shifts towards reprogramming TAMs to an anti-tumorigenic M1-like phenotype, exploring interventions such as interferons, immune checkpoint inhibitors, and small molecule modulators. Noteworthy advancements include the use of CSF1R inhibitors, CD40 agonists, and CD47 blockade, demonstrating promising results in preclinical and clinical settings. A significant section is dedicated to Chimeric Antigen Receptor (CAR) technology in macrophages (CAR-M cells). While CAR-T cells have shown success in hematological malignancies, their efficacy in solid tumors has been limited. CAR-M cells, engineered to infiltrate solid tumors, are presented as a potential breakthrough, with a focus on their development, challenges, and promising outcomes. The manuscript concludes with the exploration of third-generation CAR-M technology, offering insight into in-vivo reprogramming and nonviral vector approaches. In conclusion, understanding the complex and dynamic role of TAMs in cancer is crucial for developing effective therapeutic strategies. While early-stage TAM-targeted therapies show promise, further extensive research and larger clinical trials are warranted to optimize their targeting and improve overall cancer treatment outcomes.

Bringing PERT to Pediatrics: Initial Experience and Outcomes of a Pediatric Multidisciplinary Pulmonary Embolism Response Team (PERT)

IntroductionMultidisciplinary Pulmonary Embolism Response Teams (PERTs) streamline care of adults with life-threatening pulmonary embolism (PE). Given rarity of pediatric PE, developing a clinical, educational, and research PERT paradigm is a novel and underutilized concept in pediatrics. Research QuestionIs PERT feasible in pediatrics, and does it improve PE care? Study Design and MethodsA strategy-to-execution proposal to launch a pediatric PERT was developed for institutional buy-in. Key stakeholders collectively implemented PERT. Data were collected for the two-year pre- and post-PERT eras, and outcomes were compared. ResultsPERT implementation took 12 months. Our PERT, led by hematology, comprises of pediatric experts in emergency medicine, critical care, interventional cardiology, anesthesiology, and interventional radiology. Data on 30 patients pre-PERT and 31 post-PERT were analyzed. Pre-PERT, 10%(3/30), 13%(4/30), 20%(6/30), and 57%(17/30), and post-PERT, 3%(1/31), 10%(3/31), 16%(5/31), and 71%(22/31) were categorized as high-risk, intermediate-LOW risk, intermediate-HIGH risk, and low-risk PE, respectively. Post-PERT, there were 13 unique PERT activations. PERT was activated on all eligible PE patients and, additionally, on four low-risk PEs. Time-to-echocardiogram was shorter post-PERT (4.7 hrs vs 2 hrs, P=0.0147). Anticoagulation was ordered (90 min vs 54 min, P=0.003) and given sooner (154 min vs 113 min, P=0.049) post-PERT. There were no differences in time-to-reperfusion therapies (12 hrs pre-PERT vs 8.7 hrs post-PERT, P=0.1). Five (83.3%) of six eligible (intermediate-HIGH and high-risk) patients received reperfusion therapies in the post-PERT era compared to three (37.5%) of eight eligible patients in the pre-PERT era (P=0.0001). There were no differences in major bleeding, mortality, or length of stay in either era. InterpretationThe pediatric PERT paradigm was successfully created and adopted locally. Our PERT enhanced access to experts, facilitated timely advanced therapies, and held value for low-risk PE. The University of Texas Southwestern Medical Center (UTSW) and Children’s Health System of Texas pediatric PERT may serve as a best-practice model for streamlining care for pediatric PE.

Tumor Growth Pattern and Intra- and Peritumoral Radiomics Combined for Prediction of Initial TACE Outcome in Patients with Primary Hepatocellular Carcinoma.

Non-invasive methods are urgently needed to assess the efficacy of transarterial chemoembolization (TACE) and to identify patients with hepatocellular carcinoma (HCC) who may benefit from this procedure. This study, therefore, aimed to investigate the predictive ability of tumor growth patterns and radiomics features from contrast-enhanced magnetic resonance imaging (CE-MRI) in predicting tumor response to TACE among patients with HCC. A retrospective study was conducted on 133 patients with HCC who underwent TACE at three centers between January 2015 and April 2023. Enrolled patients were divided into training, testing, and validation cohorts. Rim arterial phase hyperenhancement (Rim APHE), tumor growth patterns, nonperipheral washout, markedly low apparent diffusion coefficient (ADC) value, intratumoral arteries, and clinical baseline features were documented for all patients. Radiomics features were extracted from the intratumoral and peritumoral regions across the three phases of CE-MRI. Seven prediction models were developed, and their performances were evaluated using receiver operating characteristic (ROC) and decision curve analysis (DCA). Tumor growth patterns and albumin-bilirubin (ALBI) score were significantly correlated with tumor response. Tumor growth patterns also showed a positive correlation with tumor burden (r = 0.634, P = 0.000). The Peritumor (AUC = 0.85, 0.71, and 0.77), Clinics_Peritumor (AUC = 0.86, 0.77, and 0.81), and Tumor_Peritumor (AUC = 0.87, 0.77, and 0.80) models significantly outperformed the Clinics and Tumor models (P < 0.05), while the Clinics_Tumor_Peritumor model (AUC = 0.88, 0.81, and 0.81) outperformed the Clinics (AUC = 0.67, 0.77, and 0.75), Tumor (AUC = 0.78, 0.72, and 0.68), and Clinics_Tumor (AUC = 0.82, 0.83, and 0.78) models (P < 0.05 or 0.053, respectively). The DCA curve demonstrated better predictive performance within a specific threshold probability range for Clinics_Tumor_Peritumor. Combining tumor growth patterns, intra- and peri-tumoral radiomics features, and ALBI score could be a robust tool for non-invasive and personalized prediction of treatment response to TACE in patients with HCC.
