RESUMO

The criteria for clinical diagnosis of neurofibromatosis type 1 (NF1) are not sensitive in young children. Recognition is easier when one of their parents has been diagnosed with this condition, and the causal mutation is known. We present a case of a girl with isolated café-au-lait spots, whose father was diagnosed with NF1. However, both were found to carry different de novo mutations in the NF1 gene. This possibility has significant implications for the diagnostic process and genetic counseling.

RESUMO

In this work, organic chemicals associated with microplastics (MPs) exposed to a coastal anthropogenized environment for up to eight weeks have been screened for, in order to discern the (de)sorption dynamics of chemicals in the marine ecosystem. Low-density polyethylene (LDPE) pellets were studied since they represent primary MPs used by the plastic industry and a relevant input of MPs into the oceans. To maximize the coverage of chemicals that could be detected, both liquid and gas chromatography coupled to quadrupole-time-of-flight (GC-QTOF and LC-QTOF, respectively) were used. In the case of LC-QTOF, an electrospray ionization source was employed, and the compounds were investigated by combining suspect and non-target screening workflows. The GC-QTOF was equipped with an electron ionization source and compounds were screened in raw and derivatized (silylated) extracts by deconvolution and contrast to high- and low-resolution libraries. A total of 50 compounds of multifarious classes were tentatively identified. Among them, melamine and 2-ethylhexyl salicylate (EHS) were detected in the original MPs but were rapidly desorbed. Melamine was completely released into the marine environment, while EHS was partly released but a portion remained bound to the MPs. On the other hand, many other chemicals of both anthropogenic (e.g. phenanthrene or benzophenone) and natural origin (e.g. betaine and several fatty acids) accumulated onto MPs over time. Quantification of 12 unequivocally identified chemicals resulted into a total concentration of 810 µg/kg after MPs exposure for 8 weeks.

RESUMO

BACKGROUND: Liver transplantation is the last therapeutic option for patients with end-stage liver disease. Postreperfusion syndrome (PRS), defined as a fall in mean arterial pressure of more than 30% within the first 5 minutes after reperfusion of at least 1 minute, can occur in liver transplantation as a deep hemodynamic instability with associated hyperfibrinolysis immediately after reperfusion of the new graft. Its incidence has remained unchanged since it was first described in 1987. PRS is related to ischemia-reperfusion (I/R) injury, whose pathophysiology involves the release of several mediators from both the donor and the recipient. The antioxidant effect of ascorbic acid has been studied in resuscitating patients with septic shock and burns. Even today, there are publications with conflicting results, and there is a need for further studies to confirm or rule out the usefulness of this drug in this group of patients. The addition of ascorbic acid to preservation solutions used in solid organ transplantation is under investigation to harness its antioxidant effect and mitigate I/R injury. Since PRS could be considered a manifestation of I/R injury, we believe that the possible beneficial effect of ascorbic acid on the occurrence of PRS should be investigated. OBJECTIVE: The aim of this randomized controlled trial is to assess the benefits of ascorbic acid over saline in the development of PRS in adult liver transplantation. METHODS: We plan to conduct a single-center randomized controlled trial at the Hospital Universitario Ramón y Cajal in Spain. A total of 70 participants aged 18 years or older undergoing liver transplantation will be randomized to receive either ascorbic acid or saline. The primary outcome will be the difference between groups in the incidence of PRS. The randomized controlled trial will be conducted under conditions of respect for fundamental human rights and ethical principles governing biomedical research involving human participants and in accordance with the international recommendations contained in the Declaration of Helsinki and its subsequent revisions. RESULTS: The enrollment process began in 2020. A total of 35 patients have been recruited so far. Data cleaning and analysis are expected to occur in the first months of 2024. Results are expected around the middle of 2024. CONCLUSIONS: We believe that this study could be particularly relevant because it will be the first to analyze the clinical effect of ascorbic acid in liver transplantation. Moreover, we believe that this study fills an important gap in the knowledge of the potential benefits of ascorbic acid in the field of liver transplantation, particularly in relation to PRS.

RESUMO

ABSTRACT Neuromuscular taping or kinesiotaping is a technique widely used in spinal disorders. However, the scientific evidence of its use in discopathies and degenerative spine pathology is unknown. This study aimed to analyze the published clinical trials on neuromuscular taping in subjects with discopathies and degenerative spinal injuries. For this purpose, a literature search was performed following PRISMA guidelines in the following databases: PubMed, Web of Science (WOS), Scopus, Medline, and Cinahl. In analyzing bias and methodological quality, we used: the PEDro scale, Van Tulder criteria, and risk of bias analysis of the Cochrane Collaboration. A total of 5 articles were included that obtained a mean score of 6.2 on the PEDro scale. There is moderate evidence that, in the short term, neuromuscular taping reduces analgesic consumption and improves the range of motion and muscle strength in the posterior musculature. In addition, there is limited evidence that it can improve quality, while the scientific evidence on the effect of neuromuscular taping on pain is contradictory. The application of neuromuscular taping on discopathies and degenerative processes of the spine should be cautiously undertaken until more conclusive results are obtained, and the long-term effects are assessed. Level of evidence I; Systematic review.


Resumo: A bandagem neuromuscular ou kinesiotaping é uma técnica de bandagem amplamente utilizada em distúrbios da coluna vertebral. Entretanto, a evidência científica para seu uso em discopatias e na patologia degenerativa da coluna são desconhecidas. Objetivo: O objetivo deste trabalho foi analisar ensaios clínicos publicados sobre bandagem neuromuscular em sujeitos com discopatias e lesões degenerativas da coluna vertebral. Para este fim, foi realizada uma pesquisa bibliográfica seguindo as diretrizes do PRISMA nas seguintes bases de dados: PubMed, Web of Science (WOS), Scopus, Medline e Cinahl. Na análise de viés e qualidade metodológica, foram utilizados: escala PEDro, critérios de Van Tulder e análise de risco de viés da Colaboração Cochrane. Um total de 5 artigos foi incluído com uma pontuação média de 6,2 na escala PEDro. Há evidências moderadas de que, a curto prazo, a bandagem neuromuscular reduz o consumo de analgésicos, melhora a amplitude de movimento e a força muscular na musculatura posterior. Além disso, há evidências limitadas de que pode melhorar a qualidade, enquanto as evidências científicas sobre o efeito da bandagem neuromuscular na dor são contraditórias. A aplicação da bandagem neuromuscular em discopatias e processos degenerativos da coluna vertebral deve ser feita com cautela até que resultados mais conclusivos sejam obtidos e os efeitos a longo prazo sejam avaliados. Nível de evidência I; Revisão sistemática.

RESUMO

Background: The aim of this study was to evaluate the impact of certain single-nucleotide polymorphisms (SNPs) in cabazitaxel activity and toxicity in patients with metastatic castration-resistant prostate cancer (mCRPC). Patients & methods: 56 SNPs in five genes (CYP3A4, CYP3A5, ABCB1, TUBB1 and CYP2C8) were genotyped in 67 mCRPC patients and their correlation with outcomes analyzed. Results:TUBB1-rs151352 (hazard ratio: 0.52) and CYP2C8-rs1341164 (hazard ratio: 0.53) were associated with better overall survival, and CYP2C8-rs1058932 with biochemical progression (odds ratio: 6.60) in multivariate analysis. ABCB1-rs17327624 correlated with severe toxicity ≥grade 3 (odds ratio: 8.56) and CYP2C8-rs11572093 with asthenia (odds ratio: 8.12). Conclusion: Genetic variants in mCRPC patients could explain different outcomes with cabazitaxel. Nonetheless, the small sample size and the high number of SNPs analyzed mean that the results are only hypothesis-generating and require further validation.

RESUMO

BACKGROUND: Tobacco use is the foremost preventable cause of death, disease, and disability in the United States. Continued tobacco use in malignant disease contributes to treatment failure and disease progression. Pharmacists are pivotal to tobacco cessation counseling, management, and follow up. METHODS: This retrospective, observational, single-center, cohort study of ambulatory cancer patients was designed to assess the impact of assisted versus "Ask, Advise, Refer" (AAR) pharmacy-driven smoking cessation interventions on patient-reported quit rates at 30- and 90-days. Those included were currently smoking or recently quit adults with a thoracic malignancy or nodule. Those in the assisted intervention were offered nicotine replacement therapy (NRT) for free according to a personalized quit plan. After July 1, 2020, patients were enrolled in the AAR intervention, whereby participants were referred to obtain NRT through insurance or external resources. Both clinical interventions were provided as standard of care. RESULTS: 129 participants were included (assisted n = 83; AAR n = 46) with baseline characteristics evenly matched. After excluding those unable to be reached at 30-days, 30 (44.8%) in the assisted intervention quit smoking versus 11 (27.5%) in the AAR intervention, p = 0.08. Lung cancer patients were more likely to report quitting at 30-days in the assisted intervention, 16 (64.0%) versus 5 (29.4%) in the AAR intervention, p = 0.03. After excluding those unable to be reached at 90-days, 30 (45.5%) in the assisted intervention quit versus 11 (35.5%) in the AAR intervention, p = 0.35. CONCLUSIONS: Pharmacy-led smoking cessation initiatives that include providing NRT are especially impactful on smoking cessation in lung cancer patients.

RESUMO

This work presents an optimized gas chromatography-electron ionization-high-resolution mass spectrometry (GC-EI-HRMS) screening method. Different method parameters affecting data processing with the Agilent Unknowns Analysis SureMass deconvolution software were optimized in order to achieve the best compromise between false positives and false negatives. To this end, an accurate-mass library of 26 model compounds was created. Then, five replicates of mussel extracts were spiked with a mixture of these 26 compounds at two concentration levels (10 and 100 ng/g dry weight in mussel, 50 and 500 ng/mL in extract) and injected in the GC-EI-HRMS system. The results of these experiments showed that accurate mass tolerance and pure weight factor (combination of reverse-forward library search) are the most critical factors. The validation of the developed method afforded screening detection limits in the 2.5-5 ng range for passive sampler extracts and 1-2 ng/g for mussel sample extracts, and limits of quantification in the 0.6-3.2 ng and 0.1-1.8 ng/g range, for the same type of samples, respectively, for 17 model analytes. Once the method was optimized, an accurate-mass HRMS library, containing retention indexes, with ca. 355 spectra of derivatized and non-derivatized compounds was generated. This library (freely available at https://doi.org/10.5281/zenodo.5647960 ), together with a modified Agilent Pesticides Library of over 800 compounds, was applied to the screening of passive samplers, both of polydimethylsiloxane and polar chemical integrative samplers (POCIS), and mussel samples collected in Galicia (NW Spain), where a total of 75 chemicals could be identified.

RESUMO

INTRODUCTION: The MAJA study compared vinflunine (VFL) plus best supportive care (BSC) maintenance therapy versus BSC alone in advanced urothelial carcinoma responsive to first-line chemotherapy. The primary end point of progression-free survival was achieved. We present the final overall survival (OS) and long-term follow-up safety analyses. PATIENTS AND METHODS: Patients were enrolled, and a subsequent post hoc analysis was performed on the basis of radiologic response or stabilization to first-line cisplatin/gemcitabine (CG) chemotherapy (4-6 cycles), according to Response Evaluation Criteria in Solid Tumors (RECIST). VFL + BSC versus BSC alone were randomly assigned until disease progression. RESULTS: At final analysis, 58 patients (66.7%) had died while 29 (33.3%) had survived; the BSC arm had higher mortality (VFL + BSC, n = 26, 59.1% vs. BSC, n = 32, 74.4%). Median follow-up of surviving patients was 38.8 months (interquartile range, 23.8-61.6). Median OS was 16.7 months (95% confidence interval, 0-34.5) in VFL and 13.2 months (95% confidence interval, 6-20.4) in the BSC groups (hazard ratio, 0.736; 95% confidence interval, 0.44-1.24, P = .182). Post hoc group division did not affect median OS in either study arm. CONCLUSION: Final analysis supported a benefit of VFL in maintenance therapy in patients with disease control after first-line treatment with CG, with no unexpected long-term adverse effects. The study was insufficiently powered to show a significant OS advantage.

RESUMO

Background and study aims: Colon capsules display images from the moment they are ingested, making the study of other extracolonic areas possible. The aim of this study was to analyze the significance of these extracolonic findings. Patients and methods: In this single-center, prospective study, 165 patients underwent colon capsule endoscopy (CCE) between September 2009 and October 2012 to rule out colonic pathology. Images were recorded, without interruptions, from the moment the capsule was ingested until its battery ran out. The study was deemed complete when the capsule had traveled from the esophagus to excretion or until the hemorrhoidal plexus was observed. Results: CCE was used for colorectal cancer (CRC) screening (81.2 %), to investigate for chronic diarrhea (9.7 %) and chronic iron deficiency anemia (6.1 %), and for patients with incomplete colonoscopy (3.0 %). The capsule returned findings in the esophagus in 52.1 % of patients, in the stomach in 45.5 % of patients, and in the small bowel in 70.7 % of patients, with the findings being considered relevant in 4.9 %, 9.7 %, and 22.6 % of patients, respectively. The whole extent of the digestive tract was fully recorded in 86.1 % of patients and the Z line could be fully observed in 57.6 % of patients. There were no adverse events. Conclusions: CCE allows the recording of images from almost the whole extent of the digestive tract in most patients, enabling relevant pathologies to be identified in extracolonic areas, particularly the small bowel. Technical and procedural improvements are still necessary in order to achieve better observation of the stomach and esophagus.

RESUMO

Despite early renal carcinoma diagnosis is more frequent nowadays, ~25-30 % of patients have metastatic disease at presentation and another ~30 % develop recurrent or metastatic disease after radical treatment for localized disease. In recent years, treatment of renal carcinoma is increasing in complexity due to the inclusion of a number of effective systemic treatments prolonging survival and increasing the therapeutic strategies for tumor debulking, or even achieving surgical complete responses and prolonged disease-free intervals. Initial multimodal approaches with immunotherapeutic agents are now being validated in patients treated with the new-targeted agents. Patients are now able to receive an optimal therapeutic strategy seeking a longer survival with an acceptable life quality and avoiding unnecessary comorbidities. In this context and as an initial therapeutic approach, it is imperative to promote patients' selection with established prognostic models within a multidisciplinary team to assess the recommendation of a cytoreductive nephrectomy (CN), metastasectomy, and/or systemic treatment. In the context of mRCC, when feasible and in patients with favorable prognostic factors, the strategy should be to consider a CN or metastasectomy for tumor debulking in order to achieve free intervals of prolonged disease. By contrast, it is recommended to evaluate whether to perform a biopsy for histological diagnosis without nephrectomy in the following situations: high surgical risk, bulky metastatic disease or in specific sites (brain or liver) or ECOG PS 3/4. The following review covers from initial to recent studies on the integration of systemic treatment and surgery in the context of metastatic disease for an optimal multimodal management in renal carcinoma.

RESUMO

OBJECTIVE: Colon capsule endoscopy (CCE) is a new endoscopic technique that is minimally invasive and allows evaluation of the colon mucosa without pain, sedation, and gas insufflation. To date, few studies have investigated the use of CCE in patients with ulcerative colitis (UC). This study compares the ability of CCE and a conventional colonoscopy to assess mucosal disease activity and the extent of inflammatory mucosa in patients with UC. METHODS: Forty-two patients (27 men, mean age 48.5 years) with known UC and indication for colonoscopy were enrolled in this single-blind, prospective study. All patients underwent CCE, followed by a colonoscopy. The activity and extent of the disease was assessed using Mayo scores and Montreal scores, respectively. RESULTS: There was a good correlation between CCE and colonoscopy in disease severity (κ=0.79; 95% confidence interval: 0.62-0.96) and extent of inflammation (κ=0.71; 95% confidence interval: 0.52-0.90) observed. The ability of CCE to assess a broad segment of distal ileum led to a change in the diagnosis of UC to ileocolonic Crohn's disease in three patients. Bowel preparation was considered adequate in 80% of the patients and no serious adverse events related to the CCE procedure or bowel preparation were reported. CONCLUSION: CCE is a safe and useful method for the evaluation of patients with UC. The ability of CCE to assess distal ileum provides an advantage to colonoscopy as CCE can identify patients who have been incorrectly diagnosed with UC, resulting in a change in their diagnosis to Crohn's disease.

RESUMO

Capsule endoscopy is nowadays the diagnostic technique of choice in the study of small bowel pathologies, allowing the non-invasive study of the entire mucosa. This has led, together with new technical advances, to the creation of two new models (PillCam ESO and PillCam Colon) for the study of esophageal and colonic diseases. These two new capsules offer an interesting alternative to conventional endoscopy in the study of the upper and lower digestive tracts, because traditional endoscopy is often unpleasant and uncomfortable for the patient, can be painful, often requires moderate or deep sedation and is not without complications (hemorrhage, perforation, etc.). PillCam Colon is particularly important for its usefulness in the diagnosis of colonic polyps, and is a potentially useful tool in cases of incomplete colonoscopy or in colorectal cancer screening, even more when most patients are reluctant to undergo screening programs due to the said disadvantages of conventional colonoscopy. This article discusses the advantages of capsule endoscopy over conventional endoscopy, its current application possibilities and indications in routine clinical practice. In the various sections of the work, we assess the application of endoscopic capsule in different sections of the digestive tract (esophagus, stomach, and colon) and finally the potential role of panendoscopy with PillCam Colon.

RESUMO

Small bowel strictures can be missed by current diagnostic methods. The Patency capsule is a new non-endoscopic dissolvable capsule which has as an objective of checking the patency of digestive tract, in a non-invasive manner. The available clinical trials have demonstrated that the Patency capsule is a good tool for assessment of the functional patency of the small bowel, and it allows identification of those patients who can safely undergo a capsule endoscopy, despite clinical and radiographic evidence of small-bowel obstruction. Some cases of intestinal occlusion have been reported with the Patency capsule, four of them needed surgery. So, a new capsule with two timer plugs (Agile capsule) has been recently developed in order to minimize the risk of occlusion. This new device stars its dissolution process earlier (30 h after ingestion) and its two timer plugs have been designed to begin the disintegration even when the device is blocked in a tight stricture.

RESUMO

AIM: Esophageal capsule endoscopy is a well tolerated procedure that does not require sedation and has proved its value for the study of the esophagus. The aim of our study was to assess the feasibility, accuracy, safety and acceptability of esophageal capsule endoscopy for the study of gastroesophageal reflux disease and esophageal varices in patients who refused conventional upper gastrointestinal endoscopy. PATIENTS AND METHODS: Thirty consecutive examinations performed in 28 patients (15 men/13 women; mean age: 58.5+/-12.4 years; range: 23-87 years) were reviewed. Twenty-five examinations were performed in 23 patients presenting with chronic gastroesophageal reflux disease symptoms and the remaining five were carried out in patients with cirrhosis for screening of esophageal varices. The procedures were done with the new PillCam ESO that harbors two viewing cupules and takes a total of 14 frames/s. Technical data (total recording time, esophageal transit time and Z-line visualization), clinical findings (Savary-Miller grade; presence and characteristics of esophageal varices or portal hypertension gastropathy), and patient's opinion (quality and comfort questionnaire) were analyzed. RESULTS: All the patients ingested and excreted the capsule without complications. Two examinations in the gastroesophageal reflux disease group were repeated; one was issued as a follow-up and the other because no images were recorded in the first capsule endoscopy. From the former, only the satisfaction questionnaire was analyzed. Mean total recording time and esophageal transit time were 1224 and 243.79 s, respectively (range: 2-1192 s). Complete study of the Z-line was possible in 23 examinations (23/29; 79.3%). Esophageal erosions were seen in 58.33% (14/24) of the examinations carried out in patients with gastroesophageal reflux disease. Nine out of 14 patients (64.29%) presented with grade I esophagitis and the other five (35.71%) with grade II esophagitis. Among the five patients with cirrhosis, small varices were visualized in one (1/5; 20%), while large varices with red spots were evidenced in the remaining three (3/5; 60%). All four patients showing esophageal varices were found to have portal hypertension gastropathy. In most examinations, patients found the capsule easy to swallow (28/30; 93.33%), asymptomatic (29/30; 96.66%), evaluated the procedure as comfortable (29/30; 96.66%), and would repeat it if necessary (30/30; 100%). CONCLUSIONS: Esophageal capsule endoscopy is an adequate alternative diagnostic method for the study of gastroesophageal reflux disease and for the screening of esophageal varices in patients refusing to undergo conventional upper gastrointestinal endoscopy.
