The hepatocyte epidermal growth factor receptor (EGFR) pathway regulates the cellular interactome within the liver fibrotic niche.

Liver fibrosis is the consequence of chronic liver injury in the presence of an inflammatory component. Although the main executors of this activation are known, the mechanisms that lead to the inflammatory process that mediates the production of pro-fibrotic factors are not well characterized. Epidermal growth factor receptor (EGFR) signaling in hepatocytes is essential for the regenerative processes of the liver; however, its potential role in regulating the fibrotic niche is not yet clear. Our group generated a mouse model that expresses an inactive truncated form of the EGFR specifically in hepatocytes (ΔEGFR mice). Here, we have analyzed the response of WT and ΔEGFR mice to chronic treatment with carbon tetrachloride (CCl4), which induces a pro-inflammatory and fibrotic process in the liver. The results indicated that the hallmarks of liver fibrosis were attenuated in CCl4-treated ΔEGFR mice when compared with CCl4-treated WT mice, coinciding with a faster resolution of the fibrotic process and ameliorated damage. The absence of EGFR activity in hepatocytes induced changes in the pattern of immune cells in the liver, with a notable increase in the population of M2 macrophages, more related to fibrosis resolution, as well as in the population of lymphocytes related to eradication of the damage. Transcriptome analysis of hepatocytes, and secretome studies of extracellular media from in vitro experiments, allowed us to elucidate the specific molecular mechanisms regulated by EGFR that mediate hepatocyte production of both pro-fibrotic and pro-inflammatory mediators; these have consequences for the deposition of extracellular matrix proteins, as well as for the immune microenvironment. Overall, our study uncovered novel mechanistic insights regarding EGFR kinase-dependent actions in hepatocytes that reveal its key role in chronic liver damage. © 2024 The Authors.

An analysis of the association between breast density and body mass index with breast cancer molecular subtypes in early breast cancer: data from a Spanish population.

PURPOSE: Breast cancer is an important health problem, like obesity and dyslipidemia, with a strong association between body mass index (BMI) and breast cancer incidence and mortality. The risk of breast cancer is also high in women with high mammographic breast density (MBD). The purpose of this study was to analyze the association between BMI and MBD according to breast cancer molecular subtypes. METHODS: This transversal, descriptive, multicenter study was conducted at three Spanish breast cancer units from November 2019 to October 2020 in women with a recent diagnosis of early breast cancer. Data were collected at the time of diagnosis. RESULTS: The study included 162 women with a recent diagnosis of early breast cancer. The median age was 52 years and 49.1% were postmenopausal; 52% had normal weight, 32% overweight, and 16% obesity. There was no association between BMI and molecular subtype but, according to menopausal status, BMI was significantly higher in postmenopausal patients with luminal A (p = 0.011) and HER2-positive (p = 0.027) subtypes. There was no association between MBD and molecular subtype, but there were significant differences between BMI and MBD (p < 0.001), with lower BMI in patients with higher MBD. Patients with higher BMI had lower HDL-cholesterol (p < 0.001) and higher insulin (p < 0.001) levels, but there were no significant differences in total cholesterol or vitamin D. CONCLUSIONS: This study showed higher BMI in luminal A and HER2-positive postmenopausal patients, and higher BMI in patients with low MBD regardless of menopausal status.

Uncovering a Novel Functional Interaction Between Adult Hepatic Progenitor Cells, Inflammation and EGFR Signaling During Bile Acids-Induced Injury.

Chronic cholestatic damage is associated to both accumulation of cytotoxic levels of bile acids and expansion of adult hepatic progenitor cells (HPC) as part of the ductular reaction contributing to the regenerative response. Here, we report a bile acid-specific cytotoxic response in mouse HPC, which is partially impaired by EGF signaling. Additionally, we show that EGF synergizes with bile acids to trigger inflammatory signaling and NLRP3 inflammasome activation in HPC. Aiming at understanding the impact of this HPC specific response on the liver microenvironment we run a proteomic analysis of HPC secretome. Data show an enrichment in immune and TGF-ß regulators, ECM components and remodeling proteins in HPC secretome. Consistently, HPC-derived conditioned medium promotes hepatic stellate cell (HSC) activation and macrophage M1-like polarization. Strikingly, EGF and bile acids co-treatment leads to profound changes in the secretome composition, illustrated by an abolishment of HSC activating effect and by promoting macrophage M2-like polarization. Collectively, we provide new specific mechanisms behind HPC regulatory action during cholestatic liver injury, with an active role in cellular interactome and inflammatory response regulation. Moreover, findings prove a key contribution for EGFR signaling jointly with bile acids in HPC-mediated actions.

Integration of the geriatric palliative care in oncological care of elderly patient with cancer.

OBJECTIVES: The objective of this article is to describe the profile of the population attended to by the palliative geriatrics clinic and to evaluate the symptomatic control derived from the care provided. METHODS: During 2017 a model based on a holistic approach was implemented, in this model the team geriatric palliative care plays a fundamental role by being part of the palliative care team and functioning as a liaison with the oncology team and other required services. We outlined the profile of 100 patients aged 70 and older seen between 2017 and 2019 at our geriatric palliative care clinic. Descriptive statistics were used. In addition, the symptoms and the care clinic model effect on the symptomatic control were analyzed, as well as the complexity of patients in palliative care with IDC-Pal. RESULTS: The patients median age was 83.5 years. Patients were classified by type of management: 47% within the supportive care group and 53% with palliative care only; 58% had metastatic disease and 84% presented at least 1 comorbidity. Frailty was observed in 78% and a Karnofsky scale of 60 or less was observed in 59% of the overall population. SIGNIFICANCE OF RESULTS: Elderly cancer patients have a complex profile and may have multiple needs. Integrating geriatric palliative care can help to provide better and personalized care along with symptomatic control. Further studies are required to establish the ideal care model for these patients. Importantly, a personalized treatment with a geriatric palliative care specialist is a key element.

Utilization of medical interventions in hospitalized Mexican adults with cancer at the end of life in a referral hospital: The importance of early palliative care.

OBJECTIVES: To investigate the impact of early vs. late palliative care (PC) on the frequency of admissions to acute hospital settings and the utilization of end-of-life (EoL) interventions in cancer decedents. METHODS: In this single-center, cross-sectional study, we examined the frequency of intensive care unit (ICU) and emergency department (ED) admissions among adult cancer decedents between 2018 and 2022 in a referral hospital in México. Additionally, we assessed EoL medical interventions, categorizing patients into 3 groups: those who received early PC (EPC), late PC (LPC), and those who did not receive PC (NPC). RESULTS: We analyzed data from 1762 patients, averaging 56 ± 16.3 years old, with a predominant representation of women (56.8%). PC was administered to 45.2% of patients, but EPC was limited to only 12.3%. The median time from the initiation of PC to death was 5 days (interquartile range: 2.0-31.5). Hematological malignancies were the most prevalent, affecting 21.5% of patients. EPC recipients demonstrated notable reductions in ICU and ED admissions, as well as diminished utilization of chemotherapy, radiotherapy (RT), antibiotics, blood transfusions, and surgery when compared to both LPC and NPC groups. EPC also exhibited fewer medical interventions in the last 14 days of life, except for RT. SIGNIFICANCE OF RESULTS: The findings of this study indicate that a significant proportion of EoL cancer patients receive PC; however, few receive EPC, emphasizing the need to improve accessibility to these services. Moreover, the results underscore the importance of thoughtful deliberation regarding the application of EoL medical interventions in cancer patients.

The respiratory syncytial virus prefusion F protein vaccine attenuates the severity of respiratory syncytial virus-associated disease in breakthrough infections in adults ≥60 years of age.

Background: Respiratory syncytial virus (RSV) is a contagious pathogen causing acute respiratory infections (ARIs). Symptoms range from mild upper respiratory tract infections to potentially life-threatening lower respiratory tract disease (LRTD). In adults ≥60 years old, vaccine efficacy of a candidate vaccine for older adults (RSVPreF3 OA) was 71.7% against RSV-ARI and 82.6% against RSV-LRTD (AReSVi-006/NCT04886596). We present the patient-reported outcomes (PROs) from the same trial at the end of the first RSV season in the northern hemisphere (April 2022). Methods: In this phase 3 trial, adults aged ≥60 years were randomized (1:1) to receive one dose of RSVPreF3 OA vaccine or placebo. PROs were assessed using InFLUenza Patient-Reported Outcome (FLU-PRO), Short Form-12 (SF-12), and EuroQol-5 Dimension (EQ-5D) questionnaires. Peak FLU-PRO Chest/Respiratory scores during the first 7 days from ARI episode onset were compared using a Wilcoxon test. Least squares mean (LSMean) of SF-12 physical functioning (PF) and EQ-5D health utility scores were estimated using mixed effects models. Results: In the RSVPreF3 OA group (N = 12,466), 27 first RSV-ARI episodes were observed versus 95 in the Placebo group (N = 12,494). Median peak FLU-PRO Chest/Respiratory scores were lower in RSVPreF3 OA (1.07) versus Placebo group (1.86); p = 0.0258. LSMean group differences for the PF and EQ-5D health utility score were 7.00 (95% confidence interval [CI]: -9.86, 23.85; p = 0.4125) and 0.0786 (95% CI: -0.0340, 0.1913; p = 0.1695). Conclusions: The RSVPreF3 OA vaccine, in addition to preventing infection, attenuated the severity of RSV-associated symptoms in breakthrough infections, with trends of reduced impact on PF and health utility.

Assessment of emotional distress in palliative care: Edmonton Symptom Assessment System-revised (ESAS-r) vs Distress Thermometer.

OBJECTIVES: To evaluate the sensitivity and specificity of the Distress Thermometer (DT) as a screening tool for emotional distress in oncological palliative care patients and to compare the DT with the Edmonton Symptom Assessment System-revised (ESAS-r) and the gold standard to determine the most appropriate assessment method in palliative psychological care. METHODS: Data were collected from psychological screening tests (ESAS-r and DT), and clinical interviews (gold standard) were conducted by a clinical psychologist specialist in palliative oncology from January 2021 to January 2022 in an oncology palliative care service. RESULTS: The sample consisted of 356 first-time patients with a diagnosis of advanced cancer in palliative care. The most frequently reported oncological diagnoses were gastrointestinal tract (49.3%) and breast (18.3%). Most patients were female (n = 206; 57.9%), 60.4% were married/with a partner, 55.4% had between 6 and 9 years of schooling, and a median age of 57 (range, 46-65) years. The cutoff of the DT was 5, with a sensitivity of 75.88% and specificity of 54.3%. Emotional problems (sadness and nervousness) had a greater area under the curve (AUC) when measured using the DT than the ESAS-r; however, only in the case of the comparative sadness and discouragement was the difference between the AUC marginally significant. SIGNIFICANCE OF RESULTS: The use of the DT as a screening tool in oncological palliative care is more effective in the evaluation of psychological needs than the ESAS-r. The DT, in addition to evaluation by an expert psychologist, allows for a more comprehensive identification of signs and symptoms to yield an accurate mental health diagnosis based on the International Classification of Diseases-11th Revision and/or Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition.

Validation of the Mexican version of the Schedule of Attitudes Toward Hastened Death in patients undergoing palliative care in Mexico.

OBJECTIVES: The Schedule of Attitudes Toward Hastened Death (SAHD) has emerged as a valid and reliable tool to assess the wish to hasten death (WTHD) among patients diagnosed with advanced cancer; however, the instrument has never been culturally adapted and validated for patients in Mexico. This study sought to validate and abbreviate the SAHD tool for use among patients attending the Palliative Care Service of the Instituto Nacional de Cancerología in Mexico. METHODS: The SAHD was culturally adapted from a previously published validation in patients from Spain. Eligible patients included Spanish literate subjects treated as outpatients in the Palliative Care Service, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-3. Patients were asked to answer the Mexican version of SAHD (SAHD-Mx) instrument and the Brief Edinburgh Depression Scale (BEDS). RESULTS: A total of 225 patients were included in the study. Median positive response in the SAHD-Mx was 2 (range 0-18). Positive correlation was identified between the SAHD-Mx scale and ECOG performance status (r = 0.188, p = 0.005), as well as BEDS (r = 0.567, p < 0.001). SAHD-Mx displayed strong internal consistency (alpha = 0.85) and adequate reliability from test-retest phone interviews (r = 0.567, p < 0.001). Using the confirmatory factor analysis model, a factor was identified and the number of items was reduced to 6, including items 4, 5, 9, 10, 13, and 18. SIGNIFICANCE OF RESULTS: The SAHD-Mx emerges as an adequate tool, with appropriate psychometric characteristics, for assessing WTHD among patients diagnosed with cancer undergoing palliative care in Mexico. .

Efficacy of perioperative gabapentin use in patients with idiopathic scoliosis undergoing fusion surgery: a systematic review and meta-analysis.

PURPOSE: This study aimed to assess whether the perioperative use of gabapentin was associated with decreased opioid use. METHODS: A meta-analysis was performed using PubMed, Embase, Scopus, and Cochrane Library. The randomized clinical trials included were focused on patients with adolescent idiopathic scoliosis who underwent posterior fusion surgery and were treated with gabapentin versus placebo medicine. The primary outcomes were opioid consumption at 24, 48, 72, and 96 h; time to introduction of oral medication, length of hospital stay, and period of urinary catheterization were also recorded. Data were combined using the Review Manager 5.4 software. RESULTS: Four randomized clinical trials with a pool of 196 adolescent patients (mean age: 14.8 ± 2.0 years) were included. At 24 and 48 h after surgery, opioid consumption was significantly lower in the gabapentin group: (standardized mean difference [SMD]: -0.50; 95% confidence interval [CI] - 0.79 to - 0.22) and (SMD: - 0.59; 95% CI - 0.88 to - 0.30), respectively. At 72 and 96 h, there were no significant differences between studies: (SMD: - 0.19; 95% CI - 0.52 to 0.13) and (SMD: 0.12; 95% CI - 0.25 to 0.50), respectively. Regarding the administration type, there were significant differences in favor of the 15 mg/kg subgroup with 600 mg at 48 h (SMD: - 0.69; 95% CI - 1.08 to - 0.30). There were no significant differences concerning the time to introduction of oral medication (MD: - 0.08; 95% CI - 0.39 to 0.23), hospitalization time (MD: - 0.12; 95% CI - 0.40 to 0.16), or period of urinary catheterization (SMD: - 0.27; 95% CI - 0.58 to 0.05). CONCLUSIONS: Gabapentin decreased opioid consumption during the first 48 h. Doses of 15 mg/kg showed superiority in reducing opioid consumption in the first 48 h. LEVEL OF EVIDENCE I: Diagnostic: individual cross-sectional studies with consistently applied reference standard and blinding.

Clinical effects of hydration, supplementary vitamins, and trace elements during end-of-life care for cancer patients.

Introduction: Introduction: current data regarding the decision on rehydration of patients with terminal-stage cancer remain controversial. Objective: the present study was to evaluate the effect of intravenous hydration and supplementary vitamins and trace elements on clinical symptoms and biochemical parameters in palliative cancer patients. Methods: a randomized clinical trial including 72 palliative cancer patients aged 18 years and older was performed at the National Cancer Institute in Mexico. Patients were divided into two groups: intervention and control, both receiving intravenous saline solution weekly for 4 weeks, but the former was also supplemented with vitamins and trace elements. Symptoms were assessed at baseline and 4 weeks after with the Edmonton Symptom Assessment Scale. Same measurements applied to biochemical parameters. Results: the mean age of the patients was 58.75 years. The most frequent cancer diagnoses were gastrointestinal (32 %). In the between-groups analysis significant improvements were found for the intervention group in anorexia (p = 0.024), pain (p = 0.030), chloride (p = 0.043), phosphorus (p = 0.001), potassium (p = 0.006), and total proteins (< 0.0001). Conclusion: we highlight the improvement in the control of most symptoms and some biochemical parameters in the intervention group receiving vitamins and oligoelements along with intravenous hydration. Further studies are needed.

Introducción: Introducción: los datos actuales sobre la decisión de rehidratación de pacientes con cáncer en fase terminal siguen siendo controvertidos. Objetivo: el presente estudio fue evaluar el efecto de la hidratación intravenosa y la suplementación con vitaminas y oligoelementos sobre los síntomas clínicos y parámetros bioquímicos en pacientes con cáncer paliativo. Métodos: en el Instituto Nacional del Cáncer de México se realizó un ensayo clínico aleatorizado que incluyó a 72 pacientes con cáncer paliativo de 18 años o más. Los pacientes se dividieron en dos grupos: intervención y control, ambos recibieron solución salina intravenosa semanalmente durante 4 semanas, pero el primero también se complementó con vitaminas y oligoelementos. Los síntomas se evaluaron al inicio del estudio y 4 semanas después con la escala de evaluación de síntomas de Edmonton. Mismas medidas aplicadas a los parámetros bioquímicos. Resultados: la edad media de los pacientes fue de 58,75 años. El diagnóstico de cáncer más frecuente fue el gastrointestinal (32 %). En el análisis entre grupos se encontraron mejoras significativas para el grupo de intervención en anorexia (p = 0,024), dolor (p = 0,030), cloro (p = 0,043), fósforo (p = 0,001), potasio (p = 0,006) y proteínas totales (< 0,0001). Conclusión: destacamos la mejoría en el control de la mayoría de los síntomas y algunos parámetros bioquímicos en el grupo de intervención que recibió vitaminas y oligoelementos junto con hidratación endovenosa. Se necesitan más estudios.

Palliative Care in Patients With Hematological Malignancies. We Have a Long Way to Go .

Background: Patients with hematological malignancies have significant and diverse palliative care needs but are not usually referred to specialist palliative care services in a timely manner, if at all. Objective: To identify the characteristics of patients with hematological malignancies referred to the palliative care service in a tertiary hospital in Mexico City. Patients: Retrospective study including consecutive patients with hematological malignancies referred to palliative care services at Mexico's National Cancer Institute. Results: Between 2011 and 2019, 5,017 patients with hematological malignancies were evaluated for first time at Mexico's National Cancer Institute. Of these, 9.1% (n = 457) were referred to palliative care. Most were male (53.4%), with a median age of 58 years. The most frequent diagnosis was non-Hodgkin lymphoma (54.9%). The primary indication for referral to palliative care was for cases wherein chemotherapy was no longer an option (disease refractory to treatment, 42.8%). The median time of referral to the palliative care service occurred 11.2 months after the first evaluation at the National Cancer Institute and death occurred on median 1.1 months after the first palliative care evaluation. Conclusion: Patients with hematological neoplasms are infrequently referred to Palliative Care at the Institute (9.1%). We found no clear referral criteria for Palliative Care referral and note that hematologists' optimism regarding a cure can delay referrals. Clearly, we have a long way to go in improving the number of patients referred, and we still saw frequent referrals near the end of life, but the high rate of outpatient referrals is encouraging.

Correlation of Prenatal and Postnatal Diagnosis in Umbilical-Portal-Systemic Venous Shunts.

INTRODUCTION: Umbilical-portal-systemic venous shunts (UPSVS) are rare anomalies in the development of the fetal venous system. There are several postnatal and prenatal classifications of hepatic venous anomalies but the link between them is missing. We aimed to review the prenatal to postnatal diagnosis correlation in UPSVS at our center. METHODS: It is a retrospective study of patients diagnosed with UPSVS between 2019 and 2021 at our institution. Demographic, obstetric, genetic, and neonatal data were reviewed with special focus on prenatal and postnatal ultrasounds. RESULTS: A total of seven patients were diagnosed with UPSVS at a median of 24 (20-34) weeks of gestational age. All patients were male and 62% were Caucasian. None of the patients had chromosomopathies or cardiac anomalies. One patient had renal ectopia, another one had a single umbilical artery, and a third one suffered from intrauterine growth retardation. An umbilico-systemic shunt (USS) was found in two patients and a ductus venosus-systemic shunt (DVSS) in the rest. Patients with USS were diagnosed postnatally with intrahepatic portosystemic shunts. One of the DVSS patients was transferred to another hospital and the other four had normal postnatal cardiac ultrasounds, with normal abdominal ultrasounds in two patients and lack of postnatally abdominal control in the other two. All babies were found to be doing well at a median follow-up of 1 month (0-24). CONCLUSION: There is a knowledge gap in the natural history of UPSVS between fetal and neonatal life. Building bridges between prenatal and postnatal research is mandatory in order to understand these rare anomalies.

Significant changes in macrophage and CD8 T cell densities in primary prostate tumors 2 weeks after SBRT.

BACKGROUND: Radiotherapy impacts the local immune response to cancers. Prostate Stereotactic Body Radiotherapy (SBRT) is a highly focused method to deliver radiotherapy often used to treat prostate cancer. This is the first direct comparison of immune cells within prostate cancers before and after SBRT in patients. METHODS: Prostate cancers before and 2 weeks after SBRT are interrogated by multiplex immune fluorescence targeting various T cells and macrophages markers and analyzed by cell and pixel density, as part of a clinical trial of SBRT neoadjuvant to radical prostatectomy. RESULTS: Two weeks after SBRT, CD68, and CD163 macrophages are significantly increased while CD8 T cells are decreased. SBRT markedly alters the immune environment within prostate cancers.
