RESUMO

The study of the brain by magnetic resonance imaging (MRI) allows to obtain detailed anatomical images, useful to describe specific encephalic structures and to analyze possible variabilities. It is widely used in clinical practice and is becoming increasingly used in veterinary medicine, even in exotic animals; however, despite its potential, its use in comparative neuroanatomy studies is still incipient. It is a technology that in recent years has significantly improved anatomical resolution, together with the fact that it is non-invasive and allows for systematic comparative analysis. All this makes it particularly interesting and useful in evolutionary neuroscience studies, since it allows for the analysis and comparison of brains of rare or otherwise inaccessible species. In the present study, we have analyzed the prosencephalon of three representative sauropsid species, the turtle Trachemys scripta (order Testudine), the lizard Pogona vitticeps (order Squamata) and the snake Python regius (order Squamata) by MRI. In addition, we used MRI sections to analyze the total brain volume and ventricular system of these species, employing volumetric and chemometric analyses together. The raw MRI data of the sauropsida models analyzed in the present study are available for viewing and downloading and have allowed us to produce an atlas of the forebrain of each of the species analyzed, with the main brain regions. In addition, our volumetric data showed that the three groups presented clear differences in terms of total and ventricular brain volumes, particularly the turtles, which in all cases presented distinctive characteristics compared to the lizards and snakes.

RESUMO

OBJECTIVE: To compare quality of life, in patients living with HIV infection with pharmaceutical care according to the CMO methodology: capacity, motivation and opportunity versus conventional follow-up. METHODS: Longitudinal, prospective, multicenter, health intervention study, conducted between October 2019 and November 2021 in 14 centers throughout Spain. Patients over 18 years of age, receiving antiretroviral treatment and attending the consultations of the participating Pharmacy Services for 1 year were included. Patients who did not have the autonomy to complete the planned questionnaires were excluded. At baseline, participating centers were randomized to continue using the same systematics of work (traditional follow-up) or to implement the CMO model using patient stratification models, goal setting in relation to pharmacotherapy, use of motivational interviewing, as well as longitudinal follow-up enabled by new technologies. The main variable was the difference in the number of dimensions positively affected in each follow-up arm at 24 weeks of follow-up according to the MOS-HIV questionnaire. In the CMO group, the interventions performed the most frequently were recorded. RESULTS: 151 patients were included. The median age was 51.35 years. A significant improvement in quality of life was found at the end of follow-up in the CMO group, reducing the number of patients with negatively affected dimensions (2/11 vs 8/11). The most frequent interventions carried out in the CMO group, according to the taxonomy, were Motivation (51,7%) and review and validation (49,4%). CONCLUSIONS: The quality of life of patients is higher in those centers that develop Pharmaceutical Care based on the CMO methodology compared to traditional follow-up.

RESUMO

OBJECTIVE: To determine the effectiveness of a pharmaceutical intervention, based on the CMO methodology (capacity, motivation and opportunity), to decrease the prevalence of the PIMDINAC concept (potentially inappropriate medication+drug interactions+non-adherence to concomitant medication) in people living with HIV infection. METHODS: Longitudinal prospective multicenter study, conducted between October 2021 and October 2022. Patients living with HIV older than 65 years, on antiretroviral treatment and concomitant drug prescription were included. Demographic, clinical, and pharmacotherapeutic variables were collected. Pharmaceutical care was provided for6 months according to the CMO model in each patient. The main variable was the percentage of patients who simultaneously fulfilled the PIMDINAC concept, comparing the baseline value with the same value at the end of the study. In addition, the percentage of patient's adherent to concomitant and antiretroviral treatment and the percentage of patients meeting the pharmacotherapeutic targets established for the prescribed medicationat 24 weeks of follow-up were compared. RESULTS: Sixty-eight patients were included. Seventy-two percent were men, with a median age of 68 years. The median number of concomitant drugs was 7. A 60.6% of the patients had polypharmacy. The prevalence of the presence of the PIMDINAC concept decreased significantly (10.3 vs. 0%). In isolation, each of the aspects also decreased significantly (p<0.031). The percentage of patients who met the objectives improved significantly from 48,5 at baseline to 88.2 (p<0.001). CONCLUSIONS: The pharmaceutical intervention based onarmaceutical intervention based on the CMO methodology significantly decreased the prevalence of the PIMDINAC concept and increased the number of patients who achieved the objectives, optimising their pharmacotherapy.

RESUMO

Se presenta el caso de una mujer de 79 años con glaucoma severo y falta de adherencia al tratamiento, que es sometida a cirugía de catarata e implante XEN® en su ojo izquierdo. Dos semanas después de la intervención se objetiva una erosión conjuntival con exposición del extremo distal del implante, por lo que se realiza una reparación quirúrgica mediante la combinación de una sutura aposicional del tubo, adaptando su trayectoria a la curvatura escleral, y el recubrimiento con injerto de membrana amniótica. Tras 6 meses de seguimiento, presenta una presión intraocular controlada, sin necesidad de tratamiento adicional, y sin mostrar progresión de su enfermedad (AU)


We report a case of a 79-year-old woman with severe glaucoma and absence of therapeutic adherence, who underwent cataract surgery and XEN® implant in her left eye. Two weeks after the intervention, conjunctival erosion was observed with exposure of the distal end of the implant, so a surgical repair was performed by combining an appositional suture of the tube, adapting its trajectory to the scleral curvature, and an amniotic membrane graft. After 6 months of follow-up, the intraocular pressure was controlled, without additional treatment needed, and no disease progression (AU)

RESUMO

Introduction Clinical trials and real-life studies have been published showing effectiveness of benralizumab in severe eosinophilic asthmatic patients. The aim of the present study is to describe super-responders to benralizumab in a series of 79 patients who completed at least 1 year of treatment, and to compare super-responders with non super-responders. Methods This is a multicenter study of the Register of Severe Asthma of the Region of Murcia (RE-ASGRAMUR) Group performed in eight hospitals under the conditions of routine clinical practice. Patients with zero exacerbations and no oral corticosteroid therapy for asthma were considered super-responders. We analyzed clinical, functional, and inflammatory parameters of selected patients. Results In all, 50 of the 79 patients (63%) met the super-responder criteria. In addition, 36% of the patients (26/71) were considered as complete responders to treatment (super--responder + Asthma Control Test [ACT] ≥ 20 + forced expiratory volume in 1 s [FEV1] ≥ 80%). The super--responders were significantly older in age (P = 0.0029), had higher eosinophils count (P = 0.0423), higher proportion of nasal polyps (P = 0.036), and they had less severe disease at baseline. After 1 year of treatment, the super-responders had higher levels of ACT questionnaire (23 vs 19, P = 0.0007) and better percentage of FEV1 (83 vs 75, P = 0.0359). Conclusion Almost two of the three patients treated with benralizumab were super--responders after 1 year of treatment and 36% had a complete response. Super-responders were associated with older age, higher eosinophils count, had nasal polyposis as comorbidity, and had less severe disease at baseline. This data illustrated the good real-life response of patients with severe eosinophilic asthma to the treatment with benralizumab (AU)

RESUMO

Failure of second-generation tyrosine kinase inhibitors (2GTKI) is a challenging situation in patients with chronic myeloid leukemia (CML). Asciminib, recently approved by the US Federal Drug Administration, has demonstrated in clinical trials a good efficacy and safety profile after failure of 2GTKI. However, no study has specifically addressed response rates to asciminib in ponatinib pretreated patients (PPT). Here, we present data on responses to asciminib from 52 patients in clinical practice, 20 of them (38%) with prior ponatinib exposure. We analyzed retrospectively responses and toxicities under asciminib and compared results between PPT and non-PPT patients.After a median follow-up of 30 months, 34 patients (65%) switched to asciminib due to intolerance and 18 (35%) due to resistance to prior TKIs. Forty-six patients (88%) had received at least 3 prior TKIs. Regarding responses, complete cytogenetic response was achieved or maintained in 74% and 53% for non-PPT and PPT patients, respectively. Deeper responses such as major molecular response and molecular response 4.5 were achieved in 65% and 19% in non-PPT versus 32% and 11% in PPT, respectively. Two patients (4%) harbored the T315I mutation, both PPT.In terms of toxicities, non-PPT displayed 22% grade 3-4 TEAE versus 20% in PPT. Four patients (20% of PPT) suffered from cross-intolerance with asciminib as they did under ponatinib.Our data supports asciminib as a promising alternative in resistant and intolerant non-PPT patients, as well as in intolerant PPT patients; the resistant PPT subset remains as a challenging group in need of further therapeutic options.

RESUMO

A 9-year-old 6-kg male castrated mixed-breed dog was admitted to the hospital as a second opinion for left-sided nephrectomy. Plain radiographs, ultrasound, excretory urography and retrograde urethrography revealed left-sided hydronephrosis and calculi in the bladder and urethra. The urethral calculi were hydropropulsed into the bladder and nephrectomy and cystotomy were performed. Three days after surgery, the patient showed preputial inflammation, pain and pollakiuria. Retrograde urethrography was repeated and extra-urethral leakage of contrast medium into the penile tissue was identified, followed by filling of the draining veins, reaching the caudal vena cava, with subsequent opacification of the right renal pelvis and ureter and opacification of a lymph node. The dog improved during hospitalisation and a retrograde urography performed 6 months after the initial surgery confirmed full recovery.

RESUMO

Evidence is accumulating that COVID-19 vaccines might induce or exacerbate autoimmune rheumatic diseases. The currently available COVID-19 vaccines include mRNA and recombinant adenoviral vector vaccines, both encoding SARS-CoV-2 spike protein production as the primary target for neutralizing antibodies. We report a case of subacute cutaneous lupus erythematosus (SCLE) following mRNA vaccination with the Pfizer mRNA vaccine BNT162b2, and summarize the current literature on CLE occurring after COVID-19 vaccination.

RESUMO

We performed a systematic review of the literature about descending necrotising mediastinitis (DNM) of odontogenic origin. In parallel, a retrospective review of this pathology was carried out in an Oral and Maxillofacial Surgery Service of a reference hospital for a population of 1,100,000 inhabitants. The main objectives were to determine changes in mortality and prevalence of this serious complication. The systematic review included 51 articles with 89 patients and our study comprised seven patients. The period of time with the highest number of cases was between 2000-2009 (38 patients). The percentage of mortality observed was 20.2% in diffuse DNM and 4.9% in localised DNM. Thirty-one patients with DNM in our review were admitted for more than 41 days. Despite evidence of a decrease in DNM cases, publications have increased over the years, but it does not appear to be due to an increase in those of odontogenic origin. The survival of DNM has improved since 1998 and remained stable since then. Despite the low prevalence of this disease, multicentre control studies are needed to achieve better evidence about this entity.

RESUMO

BACKGROUND AND PURPOSE: Although taxanes are a frequently used group of chemotherapy agents, they can, rarely, lead to macular oedema. The purpose of this article is to review and communicate, in an integrated way, the data of the cases previously reported in the literature, as well as to present a new case. MATERIAL AND METHODS: Narrative review of reports of cases of macular oedema associated with taxanes, and communication of the clinical case of a 73-year-old woman who, after treatment with paclitaxel for metastatic breast cancer, developed macular oedema that disappeared after discontinuing the drug. RESULTS: The review included 57 cases with data from 109 eyes collected in 52 articles. The large majority (76.79%) of the cases were women, and the mean age was 58.75 years. The cancer that most frequently motivated the treatment was breast cancer (60.72%), and 92.5% of cases had metastases. The most frequently associated drug was paclitaxel (52.63%). The median time to symptom development was 4.25 months. At the initial examination, 92.86% of the cases had bilateral oedema and the mean visual acuity was 0.4 (decimal scale). The mean macular thickness was 509.63 microns, and 97.83% of the eyes had no or minimal angiographic findings. In 90.57% of the cases, the treatment with taxanes was interrupted, and some other treatment was used in 43.86% of the cases, with the most widely used being acetazolamide. The outcome was favourable, to a greater or lesser extent, in 96.23% of cases. CONCLUSIONS: Despite being a rare entity, macular oedema associated with the use of taxanes is a disorder that every oncologist and ophthalmologist should be aware of, taking into account the good outcome of the condition that usually occurs when treatment is suspended.

RESUMO

Breast implants are associated with well-known common complications that have been widely studied, such as rupture and capsular contraction. However, the increasingly growing number of patients with breast implants has led to the increased likelihood of coming across less common complications; these include seromas or late infection; adenopathies in the internal mammary chain; granulomas in the capsule of the implant, which in some cases can extend beyond the fibrous capsule; desmoid tumors associated with the implants; and breast implant-associated large cell anaplastic lymphoma. This article aims to review the main uncommon complications associated with breast implants and to describe and illustrate their findings in different imaging techniques. Proper management of these complications is important; this is especially true of late seroma and the diagnosis of breast implant-associated large cell anaplastic lymphoma for their repercussions.

RESUMO

Ewing sarcoma (ES) is a primary bone marrow tumor that very rarely develops in extra­osseous tissues, such as lung. The hallmark of ES tumors is a translocation between chromosomes 11 and 22, resulting in a fusion protein, commonly referred to as EWS­FLI1. The epigenetic profile (histone acetylation and methylation enrichment of the promoter region) that may regulate the expression of the aberrant transcription factor EWS­FLI1, remains poorly studied and understood. Knowledge of epigenetic patterns associated with covalent histone modification and expression of enzymes associated with this process, can contribute to the understanding of the molecular basis of the disease, as well as to the identification of possible molecular targets involved in expression of the EWS­FLI1 gene, so that therapeutic strategies may be improved in the future. In the present study, the transcriptional activation and repression of the EWS­FLI1 fusion gene in ES was accompanied by selective deposition of histone markers on its promoter. The EWS­FLI1 fusion gene was evaluated in two patients with ES using conventional cytogenetic, fluorescence in situ hybridization and nested PCR assays, which revealed that the aberrant expression of the EWS­FLI1 gene is accompanied by enrichment of H3K4Me3, H3K9ac and H3K27ac at the promoter region.
