RESUMEN

Background: Chronic pain is one of the most common drivers of healthcare utilization and a marked domain for health disparities, as African American/Black populations experience high rates of chronic pain. Integrative Medical Group Visits (IMGV) combine mindfulness techniques, evidence-based integrative medicine, and medical group visits. In a parent randomized controlled trial, this approach was tested as an adjunct treatment in a diverse, medically underserved population with chronic pain and depression. Objective: To determine race-based heterogeneity in the effects of a mindfulness based treatment for chronic pain. Methods: This secondary analysis of the parent trial assessed heterogeneity of treatment effects along racialized identity in terms of primary patient-reported pain outcomes in a racially diverse sample suffering from chronic pain and depression. The analytic approach examined comorbidities and sociodemographics between racialized groups. RMANOVAs examined trajectories in pain outcomes (average pain, pain severity, and pain interference) over three timepoints (baseline, 9, and 21 weeks) between participants identifying as African American/Black (n = 90) vs White (n = 29) across both intervention and control conditions. Results: At baseline, African American/Black participants had higher pain severity and had significantly different age, work status, and comorbidity profiles. RMANOVA models also identified significant race-based differences in the response to the parent IMGV intervention. There was reduced pain severity in African American/Black subjects in the IMGV condition from baseline to 9 weeks. This change was not observed in White participants over this time period. However, there was a reduction in pain severity in White participants over the subsequent interval from 9 to 21 week where IMGV had no significant effect in African American/Black subjects during this latter time period. Conclusion: Interactions between pain and racialization require further investigation to understand how race-based heterogeneity in the response to integrative medicine treatments for chronic pain contribute to the broader landscape of health inequity.

RESUMEN

Weight stigma is salient across the preconception, pregnancy, and postpartum (PPP) periods because of prevailing prescriptive norms and expectations about weight and weight gain during the reproductive period. Weight stigma is associated with negative physical and psychological health outcomes for mother and child. A clearly defined, multi-level conceptual model for interventions, research, and policy is critical to mitigating the adverse effects of weight stigma in PPP populations. Conceptual models of weight stigma towards PPP women have advanced our understanding of this issue and guided evidence accumulation but there remains a gap in informing the translation of evidence into action. Guided by evidence-based paradigms for conceptual model development, this paper has two primary objectives. First, we review and summarise theories, frameworks, and models from the PPP population and general literature to inform our understanding of the development and perpetuation of weight stigma for PPP women. Second, we propose a novel comprehensive intervention-guiding conceptual model that draws from and synthesises across multiple disciplines - the SWIPE (Stigma of Weight In the PPP Experience) model. This conceptual model will help to plan coordinated, multi-layered, and effective strategies to reduce and ultimately eliminate weight stigma for PPP women.

RESUMEN

Mussel foot proteins (Mfps) possess unique binding properties to various surfaces due to the presence of L-3,4-dihydroxyphenylalanine (DOPA). Mytilus edulis foot protein-3 (Mefp-3) is one of several proteins in the byssal adhesive plaque. Its localization at the plaque-substrate interface approved that Mefp-3 plays a key role in adhesion. Therefore, the protein is suitable for the development of innovative bio-based binders. However, recombinant Mfp-3s are mainly purified from inclusion bodies under denaturing conditions. Here, we describe a robust and reproducible protocol for obtaining soluble and tag-free Mefp-3 using the SUMO-fusion technology. Additionally, a microbial tyrosinase from Verrucomicrobium spinosum was used for the in vitro hydroxylation of peptide-bound tyrosines in Mefp-3 for the first time. The highly hydroxylated Mefp-3, confirmed by MALDI-TOF-MS, exhibited excellent adhesive properties comparable to a commercial glue. These results demonstrate a concerted and simplified high yield production process for recombinant soluble and tag-free Mfp3-based proteins with on demand DOPA modification.

RESUMEN

BACKGROUND: KRAS mutation is a negative prognostic factor for colorectal liver metastases. Several studies have investigated the resection margins according to KRAS status, with conflicting results. The aim of the study was to assess the oncologic outcomes of R0 and R1 resections for colorectal liver metastases according to KRAS status. METHODS: All patients who underwent resection for colorectal liver metastases between 2010 and 2015 with available KRAS status were enrolled in this multicentric international cohort study. Logistic regression models were used to investigate the outcomes of R0 and R1 colorectal liver metastases resections according to KRAS status: wild type versus mutated. The primary outcomes were overall survival and disease-free survival. RESULTS: The analysis included 593 patients. KRAS mutation was associated with shorter overall survival (40 vs 60 months; P = .0012) and disease-free survival (15 vs 21 months; P = .003). In KRAS-mutated tumors, the resection margin did not influence oncologic outcomes. In multivariable analysis, the only predictor of disease-free survival and overall survival was primary tumor location (P = .03 and P = .03, respectively). In KRAS wild-type tumors, R0 resection was associated with prolonged overall survival (74 vs 45 months, P < .001) and disease-free survival (30 vs 17 months, P < .001). The multivariable model confirmed that R0 resection margin was associated with prolonged overall survival (hazard ratio = 1.43, 95% confidence interval: 1.01-2.03) and disease-free survival (hazard ratio = 1.42; 95% confidence interval: 1.06-1.91). CONCLUSIONS: KRAS-mutated colorectal liver metastases showed more aggressive tumor biology with inferior overall survival and disease-free survival after liver resection. Although R0 resection was not associated with improved oncologic outcomes in the KRAS-mutated tumors group, it seems to be of paramount importance for achieving prolonged long-term survival in KRAS wild-type tumors.

RESUMEN

Women in the preconception, pregnant, or postpartum period are susceptible to weight stigma, particularly due to the risk of excess weight gain during the reproductive life period and the negative effects of stigma on the health of both the mother and the child. Identifying the drivers and facilitators of weight stigma will help guide focused weight stigma prevention interventions. This systematic review aimed to identify the drivers and facilitators of weight stigma among preconception, pregnant, and postpartum women. In May 2022, Medline, Embase, PsycINFO, and the Maternity and Infant Care Database were searched for peer-reviewed articles published since 2010 using search terms weight AND stigma AND preconception, OR pregnant, OR postpartum. Of the 1724 articles identified, 34 fulfilled the inclusion criteria and were included in a narrative synthesis. Women reported facing insensitive language, misconceptions about obesity across all settings, and inappropriate media representation. The unavailability of appropriate equipment at facilities was reported by both women and health professionals. Our findings indicate that a rigorous effort by all stakeholders is necessary to promote regulatory, legal, and educational initiatives designed to reduce weight stigma and discrimination against women in the reproductive period.

RESUMEN

59-year-old man, smoker, diabetic and hypertensive. He went to the ER due to fixed abdominal pain in the epigastrium, diaphoresis, dizziness, nausea, and "coffee grounds" vomiting. On examination he presented abdominal distension and pain on palpation in the epigastrium, without peritonism. He had a BP of 235/100 mmHg and in the blood-tests, leukocytosis with neutrophilia and normal hemoglobin. An urgent abdominal CT scan was performed, identifying a 5x6 cm nodular lesion of homogeneous density attached to the wall of the second and third duodenal portions that compressed the lumen, with two vessels with active bleeding within it. Therefore, percutaneous embolization of the gastroduodenal artery was performed. Subsequently, the patient suffered an episode of severe acute pancreatitis that required ICU admission. Finally, he presented a good clinical evolution with ceasing of pain, complete reabsorption of the hematoma and resolution of the obstructive symptoms.

RESUMEN

There are multiple causes of secondary sclerosing cholangitis (SSC), including mechanical obstruction, ischemia, congenital abnormalities, cholangiopathy of the critically ill patient and rarely, chemotherapy (1,2). We present the case of a 52-year-old female with a history of left breast invasive ductal carcinoma treated with neoadjuvant chemotherapy (adriamycin, cyclophosphamide and paclitaxel), surgery and radiotherapy in March 2021. She was admitted in July 2022 due to painless jaundice and pruritus with marked serum cholestasis. Magnetic resonance cholangiopancreatography showed multiple strictures and dilatations involving the intra and extrahepatic bile ducts (Figure 1.A), without any extrinsic stenotic cause. Findings were confirmed by endoscopic retrograde cholangiopancreatography (ERCP) with cholangioscopy (Figure 1.B). Biopsies were negative for malignancy and IgG4 disease. In addition, autoantibodies were negative and serum IgG4 levels were normal. Due to these findings and the history of recent chemotherapy, the patient was diagnosed with paclitaxel-induced sclerosing cholangitis, initiating treatment with ursodeoxycholic acid. Over the following two months, she suffered two episodes of Klebsiella Pneumoniae bacteraemia due to acute cholangitis. Dilatation and placement of plastic stents in both biliary trees were performed and prophylactic antibiotherapy was started. The patient had a poor evolution and was not candidate for liver transplantation on account of a recent neoplasia. She died six months later due to sepsis secondary to multiple hepatic abscesses.

RESUMEN

Lafora disease (LD; OMIM#254780) is a rare, devastating, and fatal form of progressive myoclonus epilepsy that affects young adolescents and has no treatment yet. One of the hallmarks of the disease is the accumulation of aberrant poorly branched forms of glycogen (polyglucosans, PGs) in the brain and peripheral tissues. The current hypothesis is that this accumulation is causative of the pathophysiology of the disease. Another hallmark of LD is the presence of neuroinflammation. We have recently reported the presence of reactive glia-derived neuroinflammation in LD mouse models and defined the main inflammatory pathways that operate in these mice, mainly TNF and IL-6 signaling pathways. In addition, we described the presence of infiltration of peripheral immune cells in the brain parenchyma, which could cooperate and aggravate the neuroinflammatory landscape of LD. In this work, we have checked the beneficial effect of two compounds with the capacity to ameliorate neuroinflammation and reduce leukocyte infiltration into the brain, namely fingolimod and dimethyl fumarate. Our results indicate a beneficial effect of fingolimod in reducing reactive astrogliosis-derived neuroinflammation and T-lymphocyte infiltration, which correlated with the improved behavioral performance of the treated Epm2b-/- mice. On the contrary, dimethyl fumarate, although it was able to reduce reactive astrogliosis, was less effective in preventing neuroinflammation and T-lymphocyte infiltration and in modifying behavioral tests.

RESUMEN

Lichen sclerosus (LS) is a chronic inflammatory disease that mainly affects the anogenital area, with a higher incidence in post-menopausal women. In the long term, it can lead to loss of vulvar architecture or progress to squamous cell carcinoma. The evidence-based treatment involves high-potency topical corticosteroids in long regimens. However, second-line treatments are not well-established, including laser therapy. This current study aims to assess the level of evidence supporting this therapy. We conducted a search for primary-level studies published before April 2023 through MEDLINE/PubMed, Embase, Web of Science, Scopus, and CENTRAL, with no restrictions on the publication language or date. The methodological quality and risk of bias of the included studies were evaluated using the updated Cochrane Collaboration's tool for assessing risk of bias (RoB-2). Six studies (177 patients) met our eligibility criteria. Laser therapy was compared to topical corticosteroid treatment in five out of six studies. No significant histological differences were found, except for an increase in collagen production in the laser group. A greater reduction in itching, pain, and dyspareunia at 1 and 3 months of treatment in the laser group, as well as in the Skindex-29 at 6 months, was reported. Patient satisfaction was significantly higher among those who received laser therapy. Tolerability was excellent. No significant differences were observed in any of the previous aspects in the study compared to the placebo. In conclusion, there is not enough evidence to recommend laser therapy as a standalone treatment.

RESUMEN

OBJECTIVES: We aimed to evaluate the activity of selinexor, an oral selective inhibitor of nuclear export, in patients with recurrent or metastatic salivary gland tumors (SGT). METHODS: GEMS-001 is an open-label Phase 2 study for patients with recurrent or metastatic SGT with two parts. In Part 1 of the protocol, patients had tumor samples profiled with targeted next generation sequencing as well as immunohistochemistry for androgen receptor, HER-2 and ALK. For Part 2, patients with no targeted therapies available were eligible to receive selinexor 60 mg given twice weekly every 28 days. The primary endpoint was objective response rate. Secondary endpoints included progression-free survival (PFS) and prevalence of druggable alterations across SGT. RESULTS: One hundred patients were enrolled in GEMS-001 and underwent genomic and immunohistochemistry profiling. A total of 21 patients who lacked available matched therapies were treated with selinexor. SGT subtypes (WHO classification) included adenoid cystic carcinoma (n = 10), salivary duct carcinoma (n = 3), acinic cell carcinoma (n = 2), myoepithelial carcinoma (n = 2), carcinoma ex pleomorphic adenoma (n = 2) and other (n = 2). Of 18 evaluable patients, stable disease (SD) was observed in 17 patients (94%) (SD ≥6 months in 7 patients (39%)). However, no objective responses were observed. The median PFS was 4.9 months (95% confidence interval, 3.4-10). The most common treatment-related Grade 1-2 adverse events were nausea [17 patients (81%)], fatigue [16 patients (76%)], and dysgeusia [12 patients (57%)]. Most common treatment-related Grade 3-4 adverse events were hyponatremia [3 patients (14%)], neutrophil count decrease [3 patients (14%)] and cataracts [2 patients (10%)]. No treatment-related deaths were observed. CONCLUSIONS: Although tumor reduction was observed across participants, single agent selinexor anti-tumor activity was limited.

RESUMEN

INTRODUCTION: The clinical effect of domperidone against COVID-19 has been investigated in a double-blind phase III clinical trial (EudraCT number 2021-001228-17). Domperidone has shown in vitro antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and potential immudolatory properties through the stimulation of prolactin secretion. PATIENTS AND METHODS: The efficacy of oral domperidone plus standard of care (SOC; n = 87) versus placebo plus SOC (n = 86) was evaluated in a 28-day randomized double-blind multicentre study in primary health care centres. A total of 173 outpatients with mild-to-moderate COVID-19 were included. Three daily doses of 10 mg (30 mg/day) of domperidone or placebo were administered for 7 days. Reduction of viral load on day 4 was the primary efficay endpoint. It was estimated in saliva samples by reverse transcription-quantitative polymerase chain reaction (RT-qPCR), as the cycle thresholds detected ORF1ab, N Protein and S Protein genes. RESULTS: A significant reduction in the viral load was observed (p < 0.001) from baseline to days 4, 7 and 14 of the three genes studied with non-significant differences between domperidone and placebo groups. Twenty-three patients (13.3%) experienced adverse events, 14 patients in the domperidone group (16.1%) and 9 patients in the placebo group (10.5%). No patients needed to be hospitalized. CONCLUSION: Results do not prove the use of domperidone as antiviral in patients with COVID-19.


A 28-day double-blind clinical trial was performed to investigate the antiviral effect of domperidone, 30 mg/day for 7 days (n = 87) versus placebo (n = 86) in outpatients with mild-to-moderate COVID-19.The primary efficacy endpoint was the reduction of viral load on day 4 as compared with baseline, estimated as the cycle thresholds to detect ORF1ab, N Protein and S Protein genes by RT-qPCR in saliva samples.The study findings do not prove the use of domperidone as antiviral in patients with COVID-19.

RESUMEN

The literature on entrepreneurship and technology transfer highlights several factors that impact the creation of university Spin-Offs. However, there is a limited body of research that specifically explores the impact of university-industry collaborations on the performance creation of these spinoffs. This study aims to fill this gap by examining the effects of university-industry collaborations on the creation of Spin-Offs from two perspectives: the number of university collaborations with different companies and the number of previous collaborations between the same university-industry dyad. The research employs joint patents as a source to measure the university-industry collaborations and statistical methods to empirically examine the impact of these collaborations on Spin-Off creation. The study is based on data from 108 universities between the years 2014 and 2017. The findings of this study reveal that both the number of collaborations and specially the presence of previous collaborations between the university and industry have a positive effect on the creation of Spin-Offs. These results suggest that universities and companies should consider these findings when formulating their strategies or policies for technology transfer and innovation management by encouraging university-industry collaborations.

RESUMEN

Genetic studies in the social sciences could be augmented through the additional consideration of functional (transcriptome, methylome, metabolome) and/or multimodal genetic data when attempting to understand the genetics of social phenomena. Understanding the biological pathways linking genetics and the environment will allow scientists to better evaluate the functional importance of polygenic scores.

RESUMEN

This study evaluated the effects of different drying methods (freeze drying, vacuum drying, infrared drying, convective drying, and sun drying) on the biological properties of berries from the Chilean murta (Ugni molinae Turcz) shrub. Physical-chemical properties (proximal composition, dietary fiber, sugars) were determined. Total phenolic content through the method of Folin-Ciocalteau, the profile of phenol compounds was determined by HPLC, and antioxidant potential by DPPH and ORAC assays were also evaluated. The topic anti-inflammatory effect was evaluated by mice´s ear edema, and in vitro anti-tumoral activity was tested by MTT assay. The chemical properties of dried berries differed significantly based on the drying method: freeze-dried murta berries showed increased total phenolic content extracted over fresh and dried samples. In addition, this lyophilized extract stood out in its antioxidant potential, in both assays evaluated (DPPH and ORAC), compared to the other drying methods. Notwithstanding, vacuum- and infrared-dried murta also showed a higher ORAC value. Antioxidant potential was significantly associated with phenolic compounds catechin and pyrogallol, which were the most abundant phenolic compounds present in all samples. The anti-inflammatory activity was most effective under freeze-drying and vacuumdrying conditions. Moreover, vacuum drying and infrared drying best preserved the anti-tumoral effect on cancer cells.

RESUMEN

BACKGROUND: CD64 expression on neutrophils surface (CD64N) by flow cytometry has been validated as a rapid biomarker for bacterial infections in both peripheral blood and other biological fluids. Ascites is a common complication in cirrhotic patients that a variety of factors can cause, including bacterial infections. Manual counting of polymorphonuclear (PMN) cells in ascitic fluid and microbiologic culture are essential for its diagnosis. We aimed to validate the determination of CD64N by flow cytometry in ascitic fluid and assess its potential usefulness in the rapid identification of bacterial infections. MATERIALS AND METHODS: A prospective unicentre study was conducted. Flow cytometry was used to analyse the expression of CD64N in 77 ascitic fluid samples from the initial paracentesis of 60 cirrhotic patients in different admission episodes from November 2021 to December 2022. RESULTS: Seventeen samples were diagnosed with bacterial infection based on a positive microbiologic culture or by PMN count (>250 PMN/mm3 in ascitic fluid). The median of CD64N MFI was significantly increased in the bacterial infection group (3690.5 MFI [1635.23-6521.18] vs. 1105.9 MFI [737.3-2048.2], p < 0.001). The CD64 MFI ratio of granulocytes to lymphocytes was elevated in the bacterial infection group (13.06 [6.38-24.58] vs. 5.01 [3.38-7.36], p < 0.001). A CD64N ratio higher than 9.9 identified those patients with bacterial infection with 70.6 and 86.7% sensitivity and specificity, with an area under the curve (AUC) of 79.4%. CONCLUSION: The CD64N determined by flow cytometry on ascitic fluid could help quickly identify bacterial infections in ascites patients, allowing early antibiotic treatment.

RESUMEN

Porto-sinusoidal vascular disease (PSVD) is an uncommon cause of portal hypertension (PHT) characterized by typical manifestations of PHT in the absence of an identifiable cause such as cirrhosis or splenoportal thrombosis (1). There are different etiological factors, including oxaliplatin (2). We present the case of a 67-year-old male with a history of locally advanced rectal cancer in 2007 treated with chemotherapy (capecitabine, folinic acid, 5-fluorouracil and oxaliplatin), radiotherapy and surgery with a definitive colostomy. He was admitted for lower gastrointestinal bleeding from the colostomy with no anemia or hemodynamic repercussion. Colonoscopy was performed and no lesions were found. Abdominal computed tomography (CT) showed peristomal varices with porto-systemic collaterals at that level. There was splenomegaly, no evidence of chronic liver disease and the splenoportal axis was permeable. Laboratory tests showed chronic thrombocytopenia. Laboratory results excluded other causes of liver disease, hepatic elastography showed a value of 7.2 kPa and upper gastrointestinal endoscopy ruled out esophagogastric varices. The catheterisation of hepatic veins demonstrated a hepatic venous pressure gradient of 13.5 mmHg and liver biopsy revealed sinusoidal dilatation with sinusoidal and perivenular fibrosis. Because of the clinical context of the patient with a history of treatment with oxaliplatin, he was diagnosed with peristomal ectopic varices secondary to porto-sinusoidal vascular disease. Due to bleeding recurrence, it was finally decided to place a transjugular intrahepatic portosystemic shunt (TIPS).

RESUMEN

BACKGROUND: Basal cell carcinoma (BCC) is the most common type of skin cancer and can represent a therapeutic challenge in patients with locally advanced disease. Vismodegib is a hedgehog pathway inhibitor approved by the FDA for use in this type of tumor. We present a case series to describe our experience with the use of vismodegib. METHODS: A retrospective study that included patients treated with vismodegib at our dermatology unit was conducted. Monthly follow-up was performed, and we registered the clinical evolution and adverse reactions. RESULTS: A total of six patients with locally advanced BCCs were included (50% males and 50% females), with a mean age of 78.5 years old. The treatment was administered over a mean of 5 months. A complete response was observed in four cases and partial response in two cases. No recurrence was detected, with a median follow-up duration after discontinuation of 18 months. Most patients (83%) had at least one adverse event, and two needed dose adjustment temporarily or permanently to continue. The main adverse effect was muscle spasms (66.7%). The main limitation of our study was the small sample, which was not representative of the general population. CONCLUSIONS: Vismodegib is a safe and effective treatment for locally advanced BCC, and its role in unresectable BCC seems to be an important option in these challenging cases.
