RESUMO

RATIONALE: Anti-CD19 chimeric antigen receptor T-cell (CAR-T) therapy is a successful treatment for B-cell malignancies associated with cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Cardiovascular toxicities have also been reported in this setting. However, there is scarce data regarding development of autonomic disorders after CAR-T cell therapy. PATIENT CONCERNS: We report a case with a patient with non-Hodgkin B-cell lymphoma, refractory to 2 prior lines of immunochemotherapy, treated with CAR-T therapy. DIAGNOSES: Orthostatic hypotension secondary to autonomic dysfunction was diagnosed as manifestation of ICANS. INTERVENTIONS: The patient received metilprednisolone 1000 mg IV daily for 3 days and anakinra 100 mg IV every 6h. OUTCOMES: The vast majority of autonomic symptoms ceased and 4 months after CAR-T therapy, autonomic dysfunction was resolved. LESSONS: New-onset autonomic dysfunction can occur as manifestation of ICANS in patients who experience persistent neurologic and cardiovascular symptoms after resolution of acute neurotoxicity and should be early recognized. Differences in differential diagnosis, mechanisms and treatment approaches are discussed.

RESUMO

BACKGROUND: Perfluoroalkyl substances (PFAS) are environmental contaminants present in a wide range of consumer products and frequently detected in drinking water. They have been linked to adverse reproductive health outcomes in women, but there is limited human evidence on the association of PFAS exposure with endometriosis. OBJECTIVE/AIM: To explore the association between plasma concentrations of several PFAS, considered individually and as a mixture, and the risk of endometriosis in women of childbearing age. METHODS: Between 2018 and 2020, 42 patients with endometriosis and 90 controls undergoing abdominal surgery were recruited at two public hospitals in Granada, Spain. The presence or absence of endometriosis was ascertained by laparoscopic inspection of the pelvis and biopsy of suspected lesions (histological diagnosis). Concentrations of 10 PFAS were quantified in plasma samples from participants. Unconditional logistic regression was employed to examine associations of individual PFAS and summed concentrations of short (∑SC) and long-chain (∑LC) PFAS with odds of endometriosis, and quantile g-computation was used to assess their mixture effect. RESULTS: In models adjusted for age, schooling, and parity, perfluorotridecanoic acid (PFTrDA) was associated with higher odds of endometriosis (odds ratio [OR] = 1.74; 95 % CI = 1.11-2.73 per 2-fold increase in plasma concentrations), while marginally significant associations were found for perfluorohexane sulfonate (PFHxS) (OR = 1.45, 95 % CI = 0.94-2.21) and ∑SC PFAS (OR = 1.48; 95 % CI = 0.96-2.30). No associations were found for the remaining PFAS. The PFAS mixture was non-significantly associated with 1.7-fold higher odds of endometriosis (95 % CI = 0.73-3.80), with perfluorononanoic acid (PFNA), PFHxS, and PFTrDA being the major contributors to this effect. CONCLUSIONS: These findings suggest that exposure to certain PFAS may increase the odds of endometriosis. However, given the modest sample size, further studies are warranted to verify these results.

RESUMO

Background: Glucocorticoid metabolites are associated with body composition measures and are altered with weight status. Metabolic and bariatric surgery (MBS) results in significant changes in weight and body composition. However, MBS effects on glucocorticoid metabolites are unknown. Objective: To evaluate (i) changes in the cortisol/cortisone ratio in youth with obesity 12 months after sleeve gastrectomy (SG) compared with nonsurgical controls with obesity (NS), and (ii) associations of these changes with body composition changes. Methods: A total of 38 participants 13-25 years old with obesity (29 female) were followed for 12 months. Half underwent SG, and the other half were followed with routine care (nonsurgical, NS). Fasting blood was assessed for cortisol and cortisone using liquid chromatography-mass spectroscopy as part of metabolomic analysis, and the cortisol/cortisone ratio was calculated. A single-slice MRI of the abdomen was performed to assess subcutaneous and visceral adipose tissue (SAT, VAT). Hepatic steatosis was assessed by computed tomography (CT). Results: SG did not differ from NS for baseline clinical characteristics, other than the mean age (SG 18.0 ± 0.46 vs. NS 16.6 ± 0.50 years, P = 0.041), BMI (BMI, 47.23 ± 1.5 vs. 41.32 ± 1.1 kg/m2, P = 0.003) weight and VAT, which were higher in SG. Significant reductions were noted over 12 months in BMI, BMI z-score, VAT, and SAT within the SG versus NS groups (P ≤ 0.001). Over 12 months, groups did not differ for changes in cortisol/cortisone ratio after controlling for age at baseline (P = 0.293). The ratio trended to decrease within the SG group [-1.40 (-5.08, 0.06), P = 0.080], particularly among those that had completed puberty (P = 0.048). No associations were found between changes in the cortisol/cortisone ratio and changes in body composition. Conclusions: The cortisol/cortisone ratio trended to decrease 12 months following SG. However, no associations were found between changes in the cortisol/cortisone ratio and changes in body composition. Studies with larger numbers of participants are necessary to confirm these findings.

RESUMO

BACKGROUND: The i-gel® Plus is a modified version of the i-gel® supraglottic airway device. It contains a wider drainage port; a longer tip; ramps inside the breathing channel; and an additional port for oxygen delivery. There has been no prospective evaluation of this device in clinical practice. METHODS: This international, multicentre, prospective cohort study aimed to evaluate the performance of the i-gel Plus in adult patients undergoing elective procedures under general anaesthesia. The primary outcome was overall insertion success rate, defined as the ability to provide effective airway management through the device from insertion until the end of the surgical procedure. Secondary outcomes included device performance and incidence of postoperative adverse events. Data from the first 1000 patients are reported. RESULTS: In total, 1012 patients were enrolled; 12 forms were excluded from the final analysis due to incomplete data leaving 1000 included patients (545 female). Overall insertion success rate was 98.6%, with a first-attempt success rate of insertion of 88.2%. A significant difference between females and males was seen for the overall success rate (97.4% vs. 99.6% respectively) but not for first-attempt successful insertion. Mean (SD) oropharyngeal seal pressure was 32 (7) cmH2O. The only independent factor that increased the risk of first-attempt failure was low operator experience. Complications included desaturation < 85% in 0.6%; traces of blood on the device in 7.4%; laryngospasm in 0.5%; and gastric contents inside the bowl in 0.2% of patients. CONCLUSIONS: The i-gel Plus appears to be an effective supraglottic airway device that is associated with a high insertion success rate and a reasonably low incidence of complications.

RESUMO

Multiple sclerosis (MS) is an autoimmune neurodegenerative disease of unknown etiology characterized by infiltration of encephalitogenic cells in the central nervous system (CNS) resulting in the presence of multifocal areas of demyelination leading to neurodegeneration. The infiltrated immune cells population is composed mainly of effector CD4+ and CD8+ T lymphocytes, B cells, macrophages, and dendritic cells that secrete pro-inflammatory factors that eventually damage myelin leading to axonal damage. The most common clinical form of MS is relapsing-remitting (RR), characterized by neuroinflammatory episodes followed by partial or total recovery of neurological deficits. The first-line treatment for RRMS relapses is a high dose of glucocorticoids, especially methylprednisolone, for three to five consecutive days. Several studies have reported the beneficial effects of melatonin in the context of neuroinflammation associated with MS or experimental autoimmune encephalomyelitis (EAE), the preclinical model for MS. Therefore, the objective of this study was to evaluate the effect of the combined treatment of melatonin and methylprednisolone on the neuroinflammatory response associated with the EAE development. This study shows for the first time the protective synergistic effect of co-treatment with melatonin and methylprednisolone on reducing the severity of EAE by decreasing CD4 lymphocytes, B cells, macrophages and dendritic cells in the CNS, as well as modulating the population of infiltrated T and B cells toward regulatory phenotypes to the detriment of pro-inflammatory effector functions. In addition to the potentiation of the protective role of methylprednisolone, treatment with melatonin from the clinical onset of EAE improves the natural course of the EAE and the response to a subsequent treatment with methylprednisolone in a later relapse of the disease, pointing melatonin as potential therapeutic tool in combination with methylprednisolone for the treatment of relapses in MS.

RESUMO

Individuals living with cancer and survivors of cancer who self-identify as Hispanic experience higher pain burden and greater barriers to pain management compared with their non-Hispanic counterparts. The Society for Integrative Oncology-ASCO guideline recommends acupuncture and massage for cancer pain management. However, Hispanic individuals' expectations about these modalities remain under-studied and highlight a potential barrier to treatment utilization in this population. We conducted a subgroup analysis of baseline data from two randomized clinical trials to evaluate ethnic differences in treatment expectations about integrative pain treatment modalities among Hispanic and non-Hispanic cancer patients and survivors of cancer. The Mao Expectancy of Treatment Effects (METE) instrument was used to measure treatment expectancy for electro-acupuncture, auricular acupuncture, and massage therapy. Results of this study demonstrated that Hispanic participants reported greater expectation of benefit from electroacupuncture, auricular acupuncture, and massage (all P < 0.01). After controlling for age, gender, race, and education, Hispanic ethnicity remained significantly associated with greater expectation of benefit from integrative therapies for pain (coef.=1.47, 95% CI, 0.67-2.27). Non-white race (coef.=1.04, 95% CI, 0.42-1.65), no college education (coef.=1.16, 95% CI, 0.59-1.74), and female gender (coef.=0.94, 95% CI, 0.38-1.50) were also associated with a greater expectation of benefit from integrative therapies. Pain management should be informed by a shared decision-making approach that aligns treatment expectancy with treatment selections to optimize outcomes. Compared with non-Hispanic participants, Hispanic individuals reported higher expectation of benefit from acupuncture and massage, highlighting the potential role for integrative therapies in addressing ethnic pain disparities. Trial Registration NCT02979574 NCT04095234.

RESUMO

PURPOSE: To determine the relationship among body image, illness uncertainty, and symptom clusters in surgically treated breast cancer survivors. METHODS: A correlational, descriptive study was conducted in a convenience sample of 60 women surgically treated breast cancer survivors recruited in a private hospital and a survivor center. A questionnaire of sociodemographic characteristics, MUIS-C Scale, and QLQ-C30 and Module BR-23 were used. Variable characteristics and associations were analyzed with descriptive statistics and Pearson correlation coefficient, and exploratory factor analysis using unweighted least squares and Promax rotation was used for symptom clustering. RESULTS: A three-factor structure was found: an anxiety symptom cluster, a breast symptom cluster, and an arm symptoms, depression, and fatigue symptom cluster, explaining 46,47% of the variance. Significant correlations were found among body image and illness uncertainty (r = -0,390, p < 0,01), body image and the anxiety symptom cluster (r = 0,613, p < 0,01), illness uncertainty and the anxiety symptom cluster (r = -0,421, p < 0,01), the breast symptom cluster (r = -0,425, p < 0,01), and the arm symptoms - depression - fatigue symptom cluster (r = -0,443, p < 0,01). CONCLUSION: The relationships among all variables were statistically significant. Nurses providing care to BC survivors need to address the multidimensionality of the symptom experience and its correlates to better assist their patients. Further research is needed to elucidate the biopsychosocial underpinnings of those relationships.

RESUMO

Little is known about iron kinetics in early infancy. We administered stable iron isotopes to pregnant women and used maternal-fetal iron transfer to enrich newborn body iron. Dilution of enriched body iron by dietary iron with natural isotopic composition was used to assess iron kinetics from birth to 6 months. In breastfed (BF, n = 8), formula-fed (FF, n = 7), or mixed feeding (MF, n = 8) infants, median (interquartile range) iron intake was 0.27, 11.19 (10.46-15.55), and 4.13 (2.33-6.95) mg/day; iron absorbed was 0.128 (0.095-0.180), 0.457 (0.374-0.617), and 0.391 (0.283-0.473) mg/day (BF versus FF, P < 0.01); and total iron gains were 0.027 (-0.002-0.055), 0.349 (0.260-0.498), and 0.276 (0.175-0.368) mg/day (BF versus FF, P < 0.001; BF versus MF, P < 0.05). Isotope dilution can quantify long-term iron absorption and describe the trajectory of iron depletion during early infancy.

RESUMO

Bridging therapy (BT) after leukapheresis is required in most relapsed/refractory (R/R) large B-cell lymphoma (LBCL) patients receiving chimeric antigen receptor (CAR) T cells. Bendamustine-containing regimens are a potential BT option. We aimed to assess if this agent had a negative impact on CAR-T outcomes when it was administered as BT. We included R/R LBCL patients from six centers who received systemic BT after leukapheresis from February 2019 to September 2022; patients who only received steroids or had pre-apheresis bendamustine exposure were excluded. Patients were divided into two BT groups, with and without bendamustine. Separate safety and efficacy analyses were carried out for axi-cel and tisa-cel. Of 243 patients who received BT, bendamustine (benda) was included in 62 (26%). There was a higher rate of BT progressors in the non-benda group (62% vs. 45%, p = 0.02). Concerning CAR-T efficacy, complete responses were comparable for benda versus non-benda BT cohorts with axi-cel (70% vs. 53%, p = 0.12) and tisa-cel (44% vs. 36%, p = 0.70). Also, 12-month progression-free and overall survival were not significantly different between BT groups with axi-cel (56% vs. 43% and 71% vs. 63%) and tisa-cel (25% vs. 26% and 52% vs. 48%); there were no differences when BT response was considered. CAR T-cell expansion for each construct was similar between BT groups. Regarding safety, CRS G ≥3 (6% vs. 6%, p = 0.79), ICANS G ≥3 (15% vs. 17%, p = 0.68), severe infections, and neutropenia post-infusion were comparable among BT regimens. BT with bendamustine-containing regimens is safe for patients requiring disease control during CAR T-cell manufacturing.

RESUMO

Objective. This work sought to develop the Actuasalud platformas a useful tool for nursing that permits assessing health, in term of frailty, in population over 65 years of age. Methods. For the design and development of Actuasalud, two working groups were formed: one from nursing with different profiles, to identify the scientific content and a computer science group responsible for the software programming and development. Both teams adapted the scientific content to the technology so that the tool would allow for population screening with detection of health problems and frailty states. Results. The software was developed in three large blocks that include all the dimensions of frailty: a) sociodemographic variables, b) comorbidities, and c) assessment tools of autonomy-related needs that evaluate the dimensions of frailty. At the end of the evaluation, a detailed report is displayed through bar diagram with the diagnosis of each of the dimensions assessed. The assessment in the participating elderly showed that 44.7% (n = 38) of the population was considered not frail, and 55.3%; (n = 47) as frail. Regarding associated pathologies, high blood pressure (67.1%; n = 57), osteoarthritis and/or arthritis (55.3%; n = 47), diabetes (48.2%; n = 41) and falls during the last year (35.3%; n = 30) were highlighted. Conclusion.Actuasalud is an application that allows nursing professionals to evaluate frailty and issue a quick diagnosis with ordered sequence,which helps to provide individualized care to elderly individuals according to the problems detected during the evaluation.

RESUMO

There is growing evidence about how physical activity can improve cancer care. Unfortunately, exercise is still not widely prescribed to oncology patients, despite the benefit it brings. For this to occur, it is necessary for a multidisciplinary approach involving different types of healthcare professionals, given that each treatment be tailored for each single case. Besides incorporating appropriate infrastructures and referral pathways, we need to integrate exercise into healthcare practice, which ameliorates patients' quality of life and treatment side effects. From the Spanish Society of Medical Oncology (SEOM), and through the Exercise and Cancer Working Group, we indicate considerations, analyze patient care scenarios, and propose a referral pathway algorithm for exercise prescription, taking in account the patient's needs. In later sections of this paper, we describe how this algorithm could be implemented, and how the exercise programs should be built, including the physical activity contents, the settings, and the delivery mode. We conclude that professionals, infrastructures, and organizations should be available at every assistance level to create programs providing adequate exercise training for cancer patients.

RESUMO

Hepatocellular carcinoma (HCC) is the most common primary malignancy in the liver and is the third cause of cancer-related death worldwide. Surveillance with abdominal ultrasound should be offered to individuals at high risk for developing HCC. Accurate diagnosis, staging, and liver function are crucial when determining the optimal therapeutic approach. The BCLC staging system is widely endorsed in Western countries. Managing this pathology requires a multidisciplinary, personalized approach, generally with a multimodal strategy. Surgery remains the only curative option, albeit local and systemic therapy may also increase survival when surgery is not suitable. In advanced disease, systemic treatment should be offered to patients with ECOG/PS 0-1 and Child-Pugh class A.

RESUMO

Background: Mandibular defects resulting from oncological treatment pose significant aesthetic and functional challenges due to the involvement of bone and soft tissues. Immediate reconstruction is crucial to address complications such as malocclusion, mandibular deviation, temporomandibular joint (TMJ) changes, and soft tissue retraction. These issues can lead to functional impairments, including difficulties in chewing, swallowing, and speech. The fibula flap is widely used for mandibular reconstruction due to its long bone segment and robust vascular supply, though it may not always provide adequate bone height for optimal dental rehabilitation. This systematic review aims to determine if the double-barreled fibula flap (DBFF) configuration is a viable alternative for mandibular reconstruction and to evaluate the outcomes of dental implants placed in this type of flap. Materials and Methods: This study adhered to the Cochrane Collaboration criteria and PRISMA guidelines and was registered on the International Platform of Registered Systematic Review and Meta-Analysis Protocols Database (INPLASY2023120026). We included clinical studies published in English, Spanish, or French that focused on adult patients undergoing segmental mandibulectomy followed by DBFF reconstruction and dental rehabilitation. Data sources included Medline/PubMed, the Cochrane Library, EMBASE, Scopus, and manual searches. Two reviewers independently screened and selected studies, with discrepancies resolved by a third reviewer. Data extraction captured variables such as publication year, patient demographics, number of implants, follow-up duration, flap survival, implant failure, and aesthetic outcomes. The risk of bias was assessed using the JBI appraisal tool, and the certainty of evidence was evaluated using the GRADE approach. Results: A total of 17 clinical studies were included, evaluating 245 patients and 402 dental implants. The average patient age was 43.7 years, with a mean follow-up period of 34.3 months. Flap survival was high, with a 98.3% success rate and only four flap losses. The implant failure rate was low at 1.74%. Esthetic outcomes were varied, with only three studies using standardized protocols for evaluation. The overall certainty of evidence for flap survival was moderate, low for implant failure, and very low for aesthetics due to the subjective nature of assessments and variability in reporting. Conclusions: The primary limitations of the evidence included in this review are the observational design of the studies, leading to an inherent risk of bias, inconsistency in reporting methods, and imprecision in outcome measures. Additionally, the subjective nature of aesthetic evaluations and the variability in assessment tools further limit the reliability of the findings. The DBFF technique demonstrates excellent outcomes for mandibular reconstruction, with high flap survival and low implant failure rates, making it a viable option for dental rehabilitation. However, the evidence for aesthetic outcomes is less certain, highlighting the need for more rigorous and standardized research. This review supports the DBFF as a good alternative for mandibular reconstruction with successful dental implant integration, although further studies are needed to enhance the reliability of aesthetic evaluations.

RESUMO

BACKGROUND: Current understanding of the mechanism of action of the pericapsular nerve group (PENG) block is primarily based on cadaver studies. We performed an imaging study in patients undergoing hip surgery to enhance the understanding of the analgesic mechanisms following a PENG block. MATERIALS AND METHODS: 10 patients scheduled for hip surgery received an ultrasound-guided PENG block with 18 mL of 0.5% ropivacaine mixed with 2 mL of a contrast agent. After completion of the block, a high-resolution CT scan was performed to obtain a three-dimensional reconstruction of the injectate's dispersion. RESULTS: The CT imaging revealed that injectate was mainly confined to the epimysium of the iliacus and the psoas muscle, with a minor spread to the hip capsule. Contrast dye was detected within the iliacus and/or the psoas muscle in all patients. No observed spread to either the subpectineal plane or the obturator foramen was detected. CONCLUSION: Our study suggests that the analgesic effect of the PENG block may be related to the block of the branches of the femoral nerve traveling within the iliopsoas muscle without a spread pattern commensurate with the block of the obturator nerve. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT06062134).

RESUMO

RESUMEN Introducción: Diversos autores mencionan que una correcta planificación de una dentadura parcial removible incrementa la satisfacción de los pacientes, en cuanto a estética y función. En casos donde la estética es prioritaria, se plantea un diseño sin retenedores visibles. En estos casos, la elaboración de la dentadura no demanda mayores costos, basta con establecer el diagnóstico correspondiente valorando los pilares, eje de inserción, áreas retentivas entre otros y establecer el diseño más conveniente según sea el caso. Objetivo: El objetivo fue realizar una revisión sistematizada sobre la percepción de la calidad de vida y satisfacción en pacientes portadores de dentaduras parciales removibles. Materiales y métodos: Se incluyeron 13 artículos científicos mediante la metodología PRISMA para la identificación, revisión e inclusión de los textos que formaron parte del estudio.

ABSTRACT Introduction : Various authors mention that correct planning of a removable partial denture can offer adequate satisfaction in terms of aesthetics and function. In cases where aesthetics is a priority, a design without visible clasps is proposed. In addition, this elaboration does not demand higher costs, if the practitioner reaches the corresponding diagnosis and establishes the most convenient design for each specific case. Objective: The objective was to carry out a systematic review on the perception of quality of life and satisfaction in patients with removable partial dentures. Materials and methods: Thirteen scientific articles were included using the PRISMA methodology for the identification, review and inclusion of the texts that were part of this study. The articles were selected considering the title, abstract and objective. Systematic reviews, meta-analyses, comparative studies, and literature reviews that included criteria about satisfaction in patients with removable partial dentures where evaluated. The articles were read in their entirety: the objectives, methodology and conclusions of each one of them were analyzed. Results: The most common complaint was the aesthetic result, followed by pain during chewing. It is recommended to offer periodic control of the removable partial denture to evaluate its correct functioning and fit. Conclusion: The success of the treatment with removable partial dentures can be evaluated through the precise diagnosis of the case, considering previous experiences and taking into account the expectations of the patient. Also, understanding the patient's lifestyle, socioeconomic level, periodontal health status, and personality, may be factors that allow the practitioner to reduce the risk of future failure for the treatment with removable partial dentures.

RESUMO

Introducción: Diversos autores mencionan que una correcta planificación de una dentadura parcial removible incrementa la satisfacción de los pacientes, en cuanto a estética y función. En casos donde la estética es prioritaria, se plantea un diseño sin retenedores visibles. En estos casos, la elaboración de la dentadura no demanda mayores costos, basta con establecer el diagnóstico correspondiente valorando los pilares, eje de inserción, áreas retentivas entre otros y establecer el diseño más conveniente según sea el caso. Objetivo: El objetivo fue realizar una revisión sistematizada sobre la percepción de la calidad de vida y satisfacción en pacientes portadores de dentaduras parciales removibles. Materiales y métodos: Se incluyeron 13 artículos científicos mediante la metodología PRISMA para la identificación, revisión e inclusión de los textos que formaron parte del estudio. Se seleccionaron tomando en cuenta el título, resumen y objetivo. Fueron considerados: revisiones sistemáticas, metaanálisis, estudios comparativos y revisiones de literatura que evaluaran diferentes criterios acerca de la satisfacción en pacientes portadores de dentadura parcial removible. Los artículos fueron leídos íntegramente, se analizaron objetivos, metodología y conclusión de cada uno de ellos, y posteriormente fueron analizados. Resultados: La queja más común fue el resultado estético, seguida del dolor durante la masticación. Se recomienda ofrecer un control periódico de la prótesis parcial removible para evaluar el correcto funcionamiento y ajuste de esta. Conclusión: El éxito del tratamiento con dentaduras parciales removibles se puede optimizar mediante el diagnóstico preciso del caso, considerando experiencias previas del paciente y teniendo en cuenta sus expectativas. Asimismo, comprender ciertos factores como su estilo de vida, nivel socioeconómico, estado de salud periodontal, personalidad, puede disminuir el riesgo de fracaso futuro del tratamiento con dentaduras parciales removibles.

RESUMO

Resumen: Los cormos de malanga son tallos subterráneos con alto valor nutrimental por su contenido de carbohidratos y proteínas, además de ser altamente digestivos. El almidón que se extrae de ellos puede ser utilizado en la encapsulación de microorganismos probióticos, de gran importancia para la salud. El objetivo de este trabajo fue desarrollar un suplemento alimenticio con características funcionales, usando bacterias ácido lácticas (BAL) (Lactobacilos casei), encapsuladas en almidón de malanga (Xanthosoma sagittifolium). El suplemento se realizó mezclando 150 mL de pulpa de fruta cocida (mango o manzana) con 400 mL de suero de leche (pH de 6.0), a 45 ± 1 °C, hasta conseguir la consistencia deseada (449.9 mPas/s a una temperatura de 25 ºC). Posteriormente, se adicionaron 1 % o 2 % de almidón de malanga (p/v) y 10 mL de cultivo probiótico por cada 100 mL de mezcla. Se deshidrató a 80 ºC y 150 ºC con flujo de aire de 20 mL/min para manzana y 8 mL/min para mango mediante secado por aspersión. El rendimiento fue de 12 %, con una viabilidad de las BAL en el suplemento deshidratado a los 3 meses de almacenamiento superior a 1 x 108 UFC/g. La ausencia de bacterias coliformes, así como de salmonella y shigella, indican que los suplementos son inocuos y aptos para consumo. La composición nutrimental del suplemento de manzana obtenido fue2.23 % de fibra, 5.93 % de grasa, 4.95 % de proteína y un 79 % de hidratos de carbono; el suplemento de mango, el contenido fue 0.59 % de fibra, 7.6 % de grasa, 4.2 % de proteína y 80.20 % de hidratos de carbono. El almidón de malanga permitió la microencapsulación de las BAL y mantener su viabilidad durante el almacenamiento de los suplementos alimenticios desarrollados con base en suero de leche y fruta.


Abstract: Malanga corms are an underground stem with a high nutritional value as it contains carbohydrates and proteins, in addition to being highly digestive; The starch extracted from them can be used in the encapsulation of probiotic microorganisms, which are of great importance for human health. The objective of this work was to develop a food supplement with functional characteristics, added with lactic acid bacteria (Lactobacillus casei) (LAB), using malanga (Xanthosoma sagittifolium) starch. The supplement was obtained by mixing 150 mL of cooked fruit pulp (mango or apple) with 400 mL of sweet whey (pH of 6.0), at a temperature of 45 ± 1 °C until the desired consistency (449.9 mPas/s at a temperature of 25 °C) was achieved. Subsequently, 1 % or 2 % of malanga starch (p/v) and 10 mL of probiotic cultures were added per each 100 mL of mixture. it was then dehydrated at 80 ºC and 150 °C with an air flow of 20 mL/min for apple and 8 mL/min for mango by spray drying. The yield was 12 %, with viability of LAB in the dehydrated supplement at 3 months of storage higher than 1 x 108 CFU/g. The absence of coliform bacteria, as well as Salmonella and Shigella, indicate that the supplements are safe and suitable for consumption. The nutritional composition of the apple supplement was 2.23 % fiber, 5.93 % fat, 4.95 % protein and 79 % carbohydrates; the mango supplement content was 0.59 % fiber, 7.6 % fat, 4.2 % protein and 80.20 % carbohydrates. The malanga starch allowed the LAB microencapsulation and the maintenance of their viability during the storage of sweet whey and fruit-based food supplements.

RESUMO

Over 60% of relapsed/refractory (R/R) large B-cell lymphoma (LBCL) patients who receive chimeric antigen receptor (CAR) T cells will experience disease progression. There is no standard next line of therapy and information in this setting is scarce and heterogeneous. We analyzed 387 R/R LBCL patients who progressed after CAR T cells from July 2018 until March 2022 in Spain and the United Kingdom. Median overall survival (OS) was 5.3 months, with significant differences according to the interval between infusion and progression (<2 months [1.9 months], 2-6 months [5.2 months], and >6 months [not reached]). After progression, 237 (61%) patients received treatment. Focusing on the first subsequent therapy, overall (complete) response rates were 67% (38%) for polatuzumab-bendamustine-rituximab (POLA), 51% (36%) for bispecific antibodies (BsAb), 45% (35%) for radiotherapy (RT), 33% (26%) for immune checkpoint inhibitors (ICIs), 25% (0%) for lenalidomide (LENA), and 25% (14%) for chemotherapy (CT). In terms of survival, 12-month progression-free survival and OS was 36.2% and 51.0% for POLA, 32.0% and 50.1% for BsAb, 30.8% and 37.5% for RT, 29.9% and 27.8% for ICI, 7.3% and 20.8% for LENA, and 6.1% and 18.3% for CT. Thirty-two (14%) patients received an allogeneic hematopoietic cell transplant with median OS not reached after a median follow-up of 15.1 months. In conclusion, patients with R/R LBCL who progress within the first 2 months after CAR T-cell therapy have dismal outcomes. Novel targeted agents, such as polatuzumab and BsAbs, can achieve prolonged survival after CAR T-cell therapy failure.

RESUMO

BACKGROUND: Pseudomyxoma peritonei (PMP) is a rare peritoneal mucinous carcinomatosis with largely unknown underlying molecular mechanisms. Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy is the only therapeutic option; however, despite its use, recurrence with a fatal outcome is common. The lack of molecular characterisation of PMP and other mucinous tumours is mainly due to the physicochemical properties of mucin. RESULTS: This manuscript describes the first protocol capable of breaking the mucin barrier and isolating proteins from mucinous tumours. Briefly, mucinous tumour samples were homogenised and subjected to liquid chromatography using two specific columns to reduce mainly glycoproteins, albumins and immunoglobulin G. The protein fractions were then subjected to mass spectrometry analysis and the proteomic profile obtained was analysed using various bioinformatic tools. Thus, we present here the first proteome analysed in PMP and identified a distinct mucin isoform profile in soft compared to hard mucin tumour tissues as well as key biological processes/pathways altered in mucinous tumours. Importantly, this protocol also allowed us to identify MUC13 as a potential tumour cell marker in PMP. CONCLUSIONS: In sum, our results demonstrate that this protein isolation protocol from mucin will have a high impact, allowing the oncology research community to more rapidly advance in the knowledge of PMP and other mucinous neoplasms, as well as develop new and effective therapeutic strategies.
