RESUMEN

RNA-binding proteins (RBPs) with prion-like domains (PrLDs) phase transition to functional liquids, which can mature into aberrant hydrogels composed of pathological fibrils that underpin fatal neurodegenerative disorders. Several nuclear RBPs with PrLDs, including TDP-43, FUS, hnRNPA1, and hnRNPA2, mislocalize to cytoplasmic inclusions in neurodegenerative disorders, and mutations in their PrLDs can accelerate fibrillization and cause disease. Here, we establish that nuclear-import receptors (NIRs) specifically chaperone and potently disaggregate wild-type and disease-linked RBPs bearing a NLS. Karyopherin-ß2 (also called Transportin-1) engages PY-NLSs to inhibit and reverse FUS, TAF15, EWSR1, hnRNPA1, and hnRNPA2 fibrillization, whereas Importin-α plus Karyopherin-ß1 prevent and reverse TDP-43 fibrillization. Remarkably, Karyopherin-ß2 dissolves phase-separated liquids and aberrant fibrillar hydrogels formed by FUS and hnRNPA1. In vivo, Karyopherin-ß2 prevents RBPs with PY-NLSs accumulating in stress granules, restores nuclear RBP localization and function, and rescues degeneration caused by disease-linked FUS and hnRNPA2. Thus, NIRs therapeutically restore RBP homeostasis and mitigate neurodegeneration.

RESUMEN

Aberrant activity of the SUMOylation pathway has been associated with MYC overexpression and poor prognosis in aggressive B-cell lymphoma (BCL) and other malignancies. Recently developed small-molecule inhibitors of SUMOylation (SUMOi) target the heterodimeric E1 SUMO activation complex (SAE1/UBA2). Here, we report that activated MYC signaling is an actionable molecular vulnerability in vitro and in a preclinical murine in vivo model of MYC-driven BCL. While SUMOi conferred direct effects on MYC-driven lymphoma cells, SUMO inhibition also resulted in substantial remodeling of various subsets of the innate and specific immunity in vivo. Specifically, SUMOi increased the number of memory B cells as well as cytotoxic and memory T cells, subsets that are attributed a key role within a coordinated anti-tumor immune response. In summary, our data constitute pharmacologic SUMOi as a powerful therapy in a subset of BCL causing massive remodeling of the normal B-cell and T-cell compartment.

RESUMEN

Ripening is the most crucial process step in cheese manufacturing and constitutes multiple biochemical alterations that describe the final cheese quality and its perceived sensory attributes. The assessment of the cheese-ripening process is challenging and requires the effective analysis of a multitude of biochemical changes occurring during the process. This study monitored the biochemical and sensory attribute changes of paraffin wax-covered long-ripening hard cheeses (n = 79) during ripening by collecting samples at different stages of ripening. Near-infrared hyperspectral (NIR-HS) imaging, together with free amino acid, chemical composition, and sensory attributes, was studied to monitor the biochemical changes during the ripening process. Orthogonal projection-based multivariate calibration methods were used to characterize ripening-related and orthogonal components as well as the distribution map of chemical components. The results approve the NIR-HS imaging as a rapid tool for monitoring cheese maturity during ripening. Moreover, the pixelwise evaluation of images shows the homogeneity of cheese maturation at different stages of ripening. Among the chemical compositions, fat content and moisture are the most important variables correlating to NIR-HS images during the ripening process.

RESUMEN

BACKGROUND: Several veins have been well-recognized as acceptable conduits for infrainguinal bypass surgery when the ipsilateral greater saphenous vein is unavailable. However, there is a paucity of literature describing the brachial vein as an adequate alternative. In the absence of other viable autogenous conduits, we describe the use of a brachial vein as a successful alternative for lower extremity revascularization. METHODS: A 70-year-old man presented with a chief complaint of right calf pain. Duplex ultrasound imaging of his right lower extremity revealed right-sided 2.5 cm acutely thrombosed superficial femoral artery and popliteal artery aneurysms. The patient underwent a suction thrombectomy with tissue plasminogen activator using the Power Pulse feature and Solent catheter from the AngioJet® (Boston-Scientific, Marlborough, MA) system. To repair the thrombosed aneurysms, an open bypass was planned. Due to lack of viable alternative traditionally used venous conduits, a bypass was created using the patient's brachial vein. RESULTS: A bypass was created from the superficial femoral artery to the P2 segment of the popliteal artery using a non-reversed brachial vein with ligation of the side branches of the superficial femoral artery and popliteal artery aneurysm from within the sac lumen. Completion angiogram revealed runoff through the anterior tibial artery only. Follow-up imaging at three months demonstrated a patent brachial bypass. CONCLUSION: Brachial veins can be safely used as viable venous conduits for lower extremity bypass surgery and should therefore be considered as an alternative when more commonly used veins are unsuitable or unavailable. However, more research is needed to determine the potential opportunities and challenges this alternative may present.

RESUMEN

OBJECTIVES: Iatrogenic guidewire perforation is a well-known complication of lower extremity angioplasty that is often benign or can be easily treated with endovascular techniques. However, perforations that occur in arterial side branches may be more challenging to manage. If bleeding persists, open surgery and fasciotomy may be required to evacuate the resulting hematoma and prevent compartment syndrome. These subsequent procedures increase morbidity and, if the angioplasty was performed in the outpatient setting, necessitate patient transfer to a hospital. To address these challenges, we describe a non-invasive hemostasis technique involving serial sphygmomanometer cuff inflations over the affected site in a series of five patients who experienced this complication at our office. METHODS: We retrospectively reviewed the medical records of consecutive patients undergoing lower extremity angioplasty that were found to have an arterial guidewire perforation on completion angiogram at our outpatient center between February 2012 and February 2017. Patients found to have iatrogenic guidewire perforations were administered intravenous protamine sulfate and were transferred to the surgical recovery room. Patients received ibuprofen or acetaminophen for pain management. A blood pressure cuff was placed around the site of perforation, and patients received serial cuff inflation cycles with repeated examinations of both limbs until patients reported cessation of pain and there were no signs of a developing hematoma. Patients were observed for two hours before they were discharged home. A follow-up duplex ultrasound examination was completed within one week of the intervention. RESULTS: Over the course of five years, 536 angioplasties were performed at our outpatient office. Five of these patients experienced iatrogenic guidewire perforation (0.93%). Perforations occurred in branches of the anterior or posterior tibial artery. All of these patients were successfully managed with the aforementioned hemostasis technique. None of these patients required transfer to a hospital for further management, and no complications were reported at follow-up. CONCLUSIONS: Complications of iatrogenic guidewire perforations in lower extremity arterial side branches can be safely and effectively managed by applying external compression around the affected site with an automatic blood pressure cuff.

RESUMEN

Vasospasm-induced acute limb ischemia (ALI), also known as vasospastic limb ischemia (VLI), is a rare, underreported vascular event. Unlike thrombotic and embolic occlusive etiologies, which often warrant revascularization, vasospasm is a transient phenomenon that may be successfully managed conservatively without surgical intervention. Thus, prompt recognition and accurate diagnosis of VLI is imperative to avoid unnecessary surgical or endovascular procedures. This diagnosis, however, can pose as a challenge for clinicians, as it can present with clinical signs and symptoms near-identical to the presentation of thrombotic-induced ALI. In this report, we present a patient that experienced 2 vasospasm-induced ischemic events; the patient developed Rutherford IIb acute limb-threatening ischemia following cardiac catheterization for myocardial infarction. Computer tomography angiography findings of her right leg revealed acute occlusion suggesting the need for immediate operative intervention for limb salvage. However, due to her critical state, she instead was managed with medical treatments. Despite no intervention, the patient had full resolution of her right leg symptoms. We present this case to highlight the unusual multifocality of vasospastic events and to increase awareness of the diagnostic challenges associated with VLI.

RESUMEN

School-based mental health intervention programs have demonstrated efficacy for the prevention and reduction of depressive symptoms, though the effect tends to be variable and is often unsustained longitudinally. However, it is possible that these intervention programs may have an indirect impact on adolescent functioning via positive mediators, and that this influence may predict more durable protective benefits. This study evaluated the efficacy of the Resilient Families program for improving social-emotional skills and depressive symptoms for adolescents over a two-year period. Twenty-four secondary schools in Melbourne, Australia were randomly allocated to either Resilient Families or a control condition. 1826 students (M= 12.3, SD = .05 years at W1; 56% female) completed the curricula and subsequent surveys. Inconsistent with hypotheses, analysis with Structural Equation Modelling revealed that the program had no significant effect on social-emotional skills and these skills had no significant effects on adolescent depressive symptoms. However, family attendance at parent education events within the intervention schools was associated with longitudinal reductions in depressive symptoms. The findings highlight the importance of increasing emphasis on family and community protective factors in adolescent social-emotional development and depression prevention programs.

RESUMEN

Amyloid fibrils are self-propagating entities that spread pathology in several devastating disorders including Alzheimer's disease (AD). In AD, amyloid-ß (Aß) peptides form extracellular plaques that contribute to cognitive decline. One potential therapeutic strategy is to develop inhibitors that prevent Aß misfolding into proteotoxic conformers. Here, we design specific aromatic foldamers, synthetic polymers with an aromatic salicylamide (Sal) or 3-amino benzoic acid (Benz) backbone, short length (four repetitive units), basic arginine (Arg), lysine (Lys) or citrulline (Cit) side chains, and various N- and C-terminal groups that prevent spontaneous and seeded Aß fibrillization. Ac-Sal-(Lys-Sal)3-CONH2 and Sal-(Lys-Sal)3-CONH2 selectively inhibited Aß42 fibrillization, but were ineffective against Aß43, an overlooked species that is highly neurotoxic and frequently deposited in AD brains. By contrast, (Arg-Benz)4-CONH2 and (Arg-Sal)3-(Cit-Sal)-CONH2 prevented spontaneous and seeded Aß42 and Aß43 fibrillization. Importantly, (Arg-Sal)3-(Cit-Sal)-CONH2 inhibited formation of toxic Aß42 and Aß43 oligomers and proteotoxicity. None of these foldamers inhibited Sup35 prionogenesis, but Sal-(Lys-Sal)3-CONH2 delayed aggregation of fused in sarcoma (FUS), an RNA-binding protein with a prion-like domain connected with amyotrophic lateral sclerosis and frontotemporal dementia. We establish that inhibitors of Aß42 fibrillization do not necessarily inhibit Aß43 fibrillization. Moreover, (Arg-Sal)3-(Cit-Sal)-CONH2 inhibits formation of toxic Aß conformers and seeding activity, properties that could have therapeutic utility.

RESUMEN

Heart failure, particularly in its advanced stages, significantly impacts quality of life. Despite progress in Guideline-Directed Medical Therapy (GDMT) and invasive treatments, heart transplantation (HT) remains the primary option for severe cases. However, complications such as graft rejection present significant challenges that necessitate effective monitoring. Endomyocardial biopsy (EMB) is the gold standard for detecting rejection, but its invasive nature, associated risks, and healthcare costs have shifted interest in non-invasive techniques. Donor-derived cell-free DNA (dd-cfDNA) has gained attention as a promising non-invasive biomarker for monitoring graft rejection. Compared to EMB, dd-cfDNA detects graft rejection early and enables clinicians to adjust immunosuppression promptly. Despite its advantages, dd-cfDNA testing faces challenges, such as the need for specialized technology and potential inaccuracies due to other clinical conditions. Additionally, dd-cfDNA cannot yet differentiate between types of graft rejection, and its effectiveness in chronic rejection remains unclear. Research is ongoing to set precise standards for dd-cfDNA levels, which would enhance its diagnostic accuracy and help in clinical decisions. The article also points to the future of HT monitoring, which may involve combining dd-cfDNA with other biomarkers and integrating artificial intelligence to improve diagnostic capabilities and personalize patient care. Furthermore, it emphasizes both global and racial inequalities in dd-cfDNA testing and the ethical issues related to its use in transplant medicine.

RESUMEN

Chronic heart failure (CHF) is a progressive multifactorial condition where the role of oxidative stress may have implications in the pathogenesis of the disease. Despite growing interest among researchers and clinicians, the limited, unorganized, and divergent findings regarding the association between oxidative stress and the progression of heart failure (HF) have prompted us to conduct this study. Drawing upon the evolving nature of this research domain, this study is one of the first of its kind to present a systematic and comprehensive overview of the existing evidence regarding the role of oxidative stress production in the progression of HF. This study systematically reviews peer-reviewed empirical studies published in English, particularly focusing on the association between oxidative stress and the progression of HF. Parameters, such as publication year, study design, population demographics (size, age, and gender), types of HF, and characterization of markers in the existing studies, were reviewed. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) procedure, a thorough search was conducted on PubMed, Cochrane, Embase, and Sage databases, without any restrictions on the publication dates of articles, which yielded a total of 1,808 records on the association of oxidative stress production with clinical outcomes in HF patients. The analysis of the content of 17 articles offered a robust observation of this phenomenon, providing insights into the levels of oxidative stress, antioxidant markers, and the enzymes involved in the production of reactive oxygen species (ROS), and their association with the progression and severity of HF. The findings highlighted various knowledge gaps and future research priorities are recommended in the areas of interest and unexplored areas.

RESUMEN

Pulmonary embolism (PE) represents a significant clinical challenge that substantially impacts healthcare systems. This case report focuses on the nuances of risk stratification in PE, highlighted through the presentation of a 64-year-old female patient. The uniqueness of this case lies in the patient's atypical presentation, where decreased exercise tolerance was the sole symptom leading to the diagnosis of PE. The patient was found to have new-onset atrial fibrillation, elevated levels of N-terminal pro-brain natriuretic peptide (NT-proBNP), and signs of right ventricular strain on imaging. This scenario underscores the necessity for a comprehensive assessment in PE cases, particularly when classic symptoms (e.g., tachycardia, shortness of breath, chest pain) are absent. We explore the incidence of PE in patients diagnosed with deep vein thrombosis, examining the critical role of cardiac biomarkers, including B-type natriuretic peptide, NT-proBNP, and troponins, in prognostication and their potential use in risk assessment tools for PE patients. Additionally, the significance of electrocardiogram evaluation in these patients and its role in risk stratification is thoroughly assessed.

RESUMEN

Acute coronary syndrome (ACS) presents significant diagnostic challenges, particularly in cases with atypical presentations and complex clinical scenarios. Here, we describe the case of a 59-year-old man who presented with presyncope, bradycardia, hypotension, and later syncope, attributed to the Bezold-Jarisch reflex. Electrocardiographic findings suggested both inferior and anterior wall infarction, with dynamic changes in T-wave morphology further complicating the diagnostic process. Despite a type A Wellens' pattern indicating critical stenosis in the proximal left anterior descending (LAD) artery, coronary angiography revealed a complete thrombotic lesion in the proximal right coronary artery (RCA), necessitating urgent intervention. Despite the Wellens pattern indicating LAD involvement, RCA revascularization took precedence due to immediate thrombotic risk. This case underscores the diagnostic challenges associated with conflicting clinical manifestations in ACS and highlights the importance of individualized management strategies integrating advanced diagnostic modalities to optimize outcomes. Understanding the interplay of complex clinical presentations and employing a nuanced approach to management are crucial in effectively navigating ACS scenarios.

RESUMEN

Cardiovascular diseases (CVDs) are the leading cause of death globally. Their prevalence and mortality rates continue to rise. This narrative review explores well-known risk factors for CVDs such as dyslipidemia, hypertension, diabetes, obesity, and smoking, and their prevalence among different racial and ethnic groups. In addition, we expand the discussion to include the impact of socioeconomic status (SES) on cardiovascular outcomes. The data demonstrate that non-Hispanic Black and Hispanic populations not only exhibit higher rates of hypertension, obesity, diabetes, and smoking but also face systemic barriers linked to lower SES, which worsen their cardiovascular outcomes. These barriers include a lack of education, lower income, higher rates of unemployment, and poor living conditions. Beyond these commonly studied factors, these groups also suffer from higher levels of food and housing insecurity and a lack of adequate insurance coverage, all of which contribute to poorer health. Additionally, there is a higher prevalence of mental health disorders, such as depression and anxiety, among these populations. This further compounds the risks and adverse outcomes associated with CVDs. It is essential to conduct further research into how SES and race influence cardiovascular health and to refine risk assessment methods. Concentrating on these aspects would make it possible to create interventions designed to meet the needs of diverse communities and strategies that could potentially reduce morbidity and mortality from CVD across populations. Moreover, this review advocates for integrating comprehensive socioeconomic data into cardiovascular health strategies, which is crucial for developing effective public health initiatives.

RESUMEN

Amidst an aging population and escalating obesity prevalence, elucidating the impact of obesity on transcatheter aortic valve replacement (TAVR) outcomes becomes paramount. The so-called "obesity paradox"-a term denoting the counterintuitive association of obesity, typically a risk factor for cardiovascular diseases, with improved survival outcomes in TAVR patients relative to their leaner or normal-weight counterparts-merits rigorous examination. This review comprehensively investigates the complex relationship between obesity and the clinical outcomes associated with TAVR, with a specific focus on mortality and periprocedural complications. This study aims to deepen our understanding of obesity's role in TAVR and the underlying mechanisms of the obesity paradox, thereby optimizing management strategies for this patient demographic, tailored to their unique physiological and metabolic profiles.

RESUMEN

The IL-6-gp130-STAT3 signaling axis is a major regulator of inflammation. Activating mutations in the gene encoding gp130 and germline gain-of-function mutations in STAT3 (STAT3GOF) are associated with multi-organ autoimmunity, severe morbidity, and adverse prognosis. To dissect crucial cellular subsets and disease biology involved in activated gp130 signaling, the gp130-JAK-STAT3 axis was constitutively activated using a transgene, L-gp130, specifically targeted to T cells. Activating gp130 signaling in T cells in vivo resulted in fatal, early onset, multi-organ autoimmunity in mice that resembled human STAT3GOF disease. Female mice had more rapid disease progression than male mice. On a cellular level, gp130 signaling induced the activation and effector cell differentiation of T cells, promoted the expansion of T helper type 17 (TH17) cells, and impaired the activity of regulatory T cells. Transcriptomic profiling of CD4+ and CD8+ T cells from these mice revealed commonly dysregulated genes and a gene signature that, when applied to human transcriptomic data, improved the segregation of patients with transcriptionally diverse STAT3GOF mutations from healthy controls. The findings demonstrate that increased gp130-STAT3 signaling leads to TH17-driven autoimmunity that phenotypically resembles human STAT3GOF disease.

RESUMEN

Nationwide challenges with the lack of access to mental health care for youth have prompted efforts to integrate mental health into pediatric primary care. Kansas Kids Mental Health Access Program (KSKidsMAP) was developed to promote mental health workforce development through primary-care practitioners (PCPs) by offering free access to consultations, training, and care coordination. Kansas Kids Mental Health Access Program, a federally funded pediatric mental health care access program (PMHCA), is highly interprofessional in nature, and recommendations reflect the team composition and collaboration efforts. Therefore, a mixed-methods study was conducted to assess the type of recommendations provided to PCPs who requested case consultation services. Seven themes were identified: (1) psychotherapy; (2) diagnostic evaluation; (3) community resources; (4) pharmacotherapy; (5) patient resources and toolkits; (6) education; and (7) other health recommendations. This study highlights the multifaceted approach of KSKidsMAP in addressing PCPs' pediatric mental health concerns.

RESUMEN

OBJECTIVE: We had observed that some patients with chronic venous insufficiency (CVI) had reported their lower extremity edema was worse during warmer weather. Limited research is available regarding the seasonal variation in lower extremity edema. Patients with CVI were questioned to determine whether they had experienced significant seasonal variation in their lower extremity edema and which factors might be associated with such variation. METHODS: Consecutive patients with lower extremity edema were asked whether the edema was worse in the summer or warmer weather. Data was collected between June 2017 and August 2020. A total of 1683 patients (age range, 16-102 years; mean ± standard deviation, 62 ± 14.3 years). Of the 1683 patients, 1157 were female (mean age, 62 ± 14.13 years) and 526 were male (mean age, 62.5 ± 13.82 years). Data were also collected on the presenting symptoms, degree of venous reflux of the great saphenous vein (GSV) reported from the most recent duplex ultrasound, and the season at the time of questioning. For statistical analysis, χ2 goodness-of-fit tests and one-way analysis of variance tests were used. RESULTS: Of the 1683 patients, 56.6% had reported worsening of their lower extremity edema during warmer weather, including 62.7% of the female patients and 37.3% of the male patients. The female patients had reported significantly more worsening of their lower extremity edema (P = 7.06e-18). Female patient age was associated with whether they had experienced worsening (P = .02), with more younger patients reporting worsening. Male patient age was not associated with whether they had reported worsening (P = .97). No significant differences were found in the degree of presenting symptoms between those who had and had not reported worsening (P = .58). Also, no significant differences were found in the degree of venous reflux between the right (P = .61) and left (P = .89) GSV between those who had and had not reported worsening. The season in which the patients had presented during the study period was associated with whether they had reported worsening edema. The patients who had been questioned in the winter (December, January, February) and summer (June, July, August) had reported more worsening of their edema in the warmer months (P = .008 and P = .0002, respectively). The patients who had been questioned in the spring (March, April, May) and fall (September, October, November) had not reported significantly more worsening of their edema in the warmer months (P = .167 and P = .119, respectively). CONCLUSIONS: Of the 1683 patients surveyed, 56.6% had reported worsened edema in the warmer weather. The women (especially the younger women) in the present study had experienced significant worsening, although the men had not. The degree of GSV venous reflux and severity of the presenting symptoms of the patients was not associated with whether worse edema had been reported. However, the season in which the patients had been questioned was associated with the report of worsening edema. The patients questioned in the coldest and warmest months had reported significantly more worsening. The patients questioned in the milder months had not reported significantly more worsening. These findings suggest that a sex and age bias exists in the seasonal variation of lower extremity edema in patients with CVI.

RESUMEN

BACKGROUND: In recent years, the prevalence of childhood emotional abuse has surpassed other forms of maltreatment. Childhood verbal abuse (CVA) is a key attribute of emotional abuse, yet CVA is not recognized as its own form of maltreatment and thus, has not received adequate attention. Clear terminology, definitions, and measures are needed to aid in assessing the occurrence and impact of CVA for its recognition and prevention. OBJECTIVE: We aim to synthesize the evidence on the terms, definitions, and measurements of CVA and identify outcomes associated with CVA. PARTICIPANTS AND SETTING: A systematic review focused on adult perpetration of CVA among children and adolescents using clinical, community-based, and population-based samples. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed and four databases were utilized in May 2022: PsycINFO, MEDLINE, EMBASE, and ProQuest. A total of 149 quantitative and 17 qualitative studies were identified. RESULTS: Across studies reviewed, the most common perpetrators of CVA were parents, mothers, and teachers. Definitional themes for CVA included negative speech volume, tone, and speech content, and their immediate impact. The most frequent measures cited were Adverse Childhood Experiences Study (ACE) Questionnaire and the Conflict Tactics Scale (CTS); 50 % used self-created measures. CVA was associated with a range of internalizing and externalizing outcomes across the lifespan. CONCLUSIONS: Recognizing CVA as a form of maltreatment will be a starting point for its identification and prevention. Primary prevention of CVA using trauma-informed approaches must include adult training on the importance of safety, support, and nurturance during verbal communication with children.
