The expanding role of sonography for the diagnosis of deep infiltrating endometriosis: Results of a large case series.

OBJECTIVE: To investigate the value of the sonographic identification of deep infiltrating endometriosis (DIE) in women presenting with complaints suggestive of DIE. Sonography findings were correlated with subsequent surgical exploration, and histologic verification. METHODS: A retrospective observational case series was investigated to document the ability of the use of sonography to accurately detect the presence of deep infiltrating endometriosis. The clinical observations were performed consistent with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) recommendations for observational studies. Recognizing the real-world office setting for this may introduce the importance of the practical clinical aspects of diagnostic procedures in general. RESULTS: Three-dimensional transvaginal sonography was able to accurately identify deep invasive endometriosis in 92% of the 100 women subjectively complaining of the associated symptoms of endometriosis, who underwent sonography, surgical exploration, and pathologic analysis. Additional sonographic evidence of pelvic pathology was found during the course of this investigation, perhaps complementing other means for diagnosing endometriosis. CONCLUSION: Three-dimensional transvaginal sonography is a diagnostic tool that can effectively identify deep infiltrating endometriosis, which may otherwise go undetected and untreated. These findings should encourage the use of sonography for the detection of this subtype of endometriosis.

Innovative processes in smart packaging. A systematic review.

Smart packaging provides one possible solution that could reduce greenhouse gas emissions. In comparison with traditional packaging, which aims to extend the product's useful life and to facilitate transport and marketing, smart packaging allows increased efficiency, for example by ensuring authenticity and traceability from the product's origin, preventing fraud and theft, and improving security. Consequently, it may help to reduce pollution, food losses, and waste associated with the food supply chain. However, some questions must be answered to fully understand the advantages and limitations of its use. What are the most suitable smart packaging technologies for use in agro-industrial subsectors such as meat, dairy, fruits, and vegetables, bakery, and pastry? What are the opportunities from a perspective of life extension, process optimization, traceability, product quality, and safety? What are the future challenges? An up-to-date, systematic review was conducted of literature relevant to the application of indicator technologies, sensors, and data carriers in smart packaging, to answer these questions. © 2022 Society of Chemical Industry.

Efficacy of Tofacitinib in the Treatment of Psoriatic Arthritis: A Systematic Review.

INTRODUCTION: Therapeutic approaches for psoriatic arthritis (PsA) include non-pharmacologic therapies, symptomatic treatments, tumor necrosis factor inhibitors, interleukin inhibitors, cytotoxic T lymphocyte antigen 4 immunoglobulin, and Janus kinase inhibitors. This systematic review aimed to provide complete and up-to-date information on efficacy of tofacitinib in the treatment of PsA, giving special attention to non-skin manifestations (peripheral arthritis, axial disease, enthesitis, and dactylitis). METHODS: A search of studies published between January 2016 and June 2020 was carried out on PubMed and Google Scholar. RESULTS: The number of studies with tofacitinib in PsA is limited and most of them are post hoc analyses from OPAL Broaden and OPAL Beyond. Tofacitinib has been demonstrated to be efficacious for the treatment of all disease manifestations in PsA. Superior effectivity to placebo is achieved at the earliest time point evaluated, and maintained over time. Patients who switch from placebo to tofacitinib show the same improvements; however, the time to initial response is faster in patients who firstly receive tofacitinib, compared with those switching subsequently. Additional data suggest that tofacitinib may be also effective for the treatment of the axial domain. CONCLUSIONS: Tofacitinib has been demonstrated to be efficacious for the treatment of peripheral and axial involvement, enthesitis, and dactylitis manifestation in PsA. Further prospective and long-term studies are required to corroborate and complete the present results. Similarly, real-world evidence is also necessary to complement the information obtained in clinical trials, and thereby to have a better overview of real efficacy and safety of the drug.

Clinical impact of nailfold capillaroscopy in daily clinical practice. / Impacto clínico de la capilaroscopia periungueal en la práctica clínica diaria.

INTRODUCTION: Nailfold capillaroscopy (NC) is useful in the evaluation of Raynaud's phenomenon, associated with some connective tissue diseases and in the follow-up of patients with systemic sclerosis. Our study evaluates the impact of NC in the diagnosis, according to the reason for the request and profile of autoantibodies in daily clinical practice. MATERIAL AND METHODS: All patients that undergone at least one NC between June 2012 and December 2017 were included. Clinical records were reviewed and analysed in a dichotomous way (yes/no), to see whether the NC contributed to a change of diagnosis in subsequent consultations. In addition, demographic, clinical and laboratory data were collected, and the relationship with NC patterns evaluated. RESULTS: Of the 530 patients who had undergone at least one NC, 266 had Raynaud's phenomenon as primary indication for the technique. Of those, 20 patients (3.8%) had a diagnostic change in the post-NC consultation; 15 were diagnosed with systemic sclerosis, 4 with undifferentiated connective tissue disease and one with mixed connective tissue disease. All patients had, except for one patient diagnosed with undifferentiated connective tissue disease, positive antinuclear antibodies titres, 11 of them had disease specific antibodies (9 anti-centromere, one anti-Scl70 and other anti-RNPC). The positivity of antinuclear antibodies titres was associated with a higher probability of presenting a scleroderma pattern in the NC, and all patients with a specific rheumatological diagnosis had an abnormal NC. CONCLUSION: NC is a useful technique, but with limited impact in the diagnosis of connective tissue diseases. Autoantibody positivity is associated with a greater likelihood of presenting pathological NC patterns.

An exploratory study to determine whether infliximab modifies levels of rheumatoid factor and antibodies to cyclic citrullinated peptides in rheumatoid arthritis patients.

OBJECTIVES: The aim of this study was to investigate the relationship between serum infliximab (IFX) levels and changes of RF and ACPA levels in patients with rheumatoid arthritis (RA). METHODS: Enzyme-linked immunosorbent assays (ELISA) [Promonitor® IFX R1 (version 2) (Progenika Biopharma, Spain)] were used to measure drug levels and antidrug-antibodies (ADAb) in IFX RA-treated patients (n=19). Disease activity was assessed using DAS28. IgM rheumatoid factor (RF) and IgM, IgA and IgG anti-cyclic citrullinated peptide (ACPA) were determined through ELISA. RESULTS: A significant decrease in RF (p=0.01), ACPA IgG (p=0.007), IgM (p=0.01) and IgA (p=0.03) was observed in patients presenting adequate levels of serum IFX. No significant changes to RF or ACPA were observed in patients with undetectable IFX. CONCLUSIONS: Data from this study support the hypothesis that the anti-TNF antagonist IFX downregulates autoantibody levels in RA patients when IFX levels are detectable. Larger-scale studies need to be performed to establish RF and ACPA presence as therapeutic response predictive factors.

Sensibilidad in vitro de cepas cubanas de Aspergillus spp. de origen clínico y ambiental / In vitro susceptibility of Cuban Aspergillus spp. strains of clinical and environmental origin

Introducción. En Cuba se desconoce el comportamiento de la sensibilidad de Aspergillus spp. a los antifúngicos recomendados para el tratamiento de la aspergilosis: la anfotericina B, el itraconazol, el voriconazol y las equinocandinas. La influencia del ambiente puede condicionar la aparición de resistencia en estos microorganismos. Objetivo. Evaluar la sensibilidad in vitro de cepas de Aspergillus spp. a la anfotericina B, el itraconazol y el voriconazol, y la relación de los patrones de sensibilidad con su origen. Materiales y métodos. Se determinaron las concentraciones inhibitorias mínimas de la anfotericina B, el itraconazol y el voriconazol para 60 cepas de Aspergillus spp. de origen clínico y ambiental mediante el método M38-A2 del Clinical and Laboratory Standard Institute. Resultados. Se encontraron 21 cepas resistentes a la anfotericina B (principalmente en muestras clínicas y ambientes hospitalarios) y tres cepas resistentes al itraconazol (en ambientes interiores y exteriores no hospitalarios). No se hallaron cepas resistentes al voriconazol. No se encontró relación entre el origen de las cepas y su sensibilidad. Conclusiones. Se sugiere la posible existencia de factores ambientales o interacciones con genotipos resistentes que pueden dar origen a fenotipos resistentes en Cuba. Este es el primer reporte del país de cepas de Aspergillus spp. resistentes in vitro. Los resultados ameritan ampliar el estudio para incluir análisis moleculares y filogenéticos.

Introduction: The behavior of antifungal susceptibility of Aspergillus spp. in Cuba remains unknown. The antifungals recommended to treat aspergillosis are amphotericin B, itraconazole, voriconazole and echinocandins. The influence of the environment may set off the emergence of drug-resistance in these microorganisms. Objective: To evaluate in vitro susceptibility of Aspergillus spp. strains to amphotericin B, itraconazole and voriconazol, and the relationship between susceptibility patterns and their origin. Materials and methods: Minimum inhibitory concentrations of amphotericin B, itraconazole and voriconazole were determined for 60 Aspergillus spp. strains of clinical and environmental origin using the M38-A2 method of the Clinical and Laboratory Standards Institute. Results: We found 21 amphotericin B resistant strains (mainly from clinical samples and hospital environments), as well as three itraconazole resistant strains (from non-hospital outdoor and indoor environments). No voriconazole resistance was found. No relationship was found between strain origin and susceptibility. Conclusions: Results suggest the possible existence of environmental factors or interactions with resistant genotypes which may give rise to resistant phenotypes in our country. This is the first report of in vitro Aspergillus spp. resistant strains in Cuba. These studies should be broadened and include molecular and phylogenetic analyses.

Describir variantes de secuencia en los genes BRCA1 y BRCA2 en una muestra de pacientes colombianas con historia personal o familiar de cáncer de mama sugestiva de riesgo genético.Materiales y métodos: serie de casos compuesta por 67 pacientes que fueron remitidas para estudio genético por sospecha de síndrome de cáncer de mama y ovario hereditario (HBOC). De los 67 casos, 42 (62,7 %) cumplieron con los criterios de indicación médica de la National Comprehensive Cancer Network (NCCN) del 2013, y en ellos se realizó secuenciación completa de los genes BRCA1 y BRCA2. Se determinó la frecuencia de mutación, variantes de secuencia y significancia clínica de las variantes halladas con base en Breast Cancer Information Core (BIC).Resultados: se identificaron mutaciones para el gen BRCA1 en seis pacientes (14,3 %), no se documentó mutación para el gen BRCA2, además se detectaron 43 variantes genéticas en 27 pacientes (64,2 % de 42 casos). De estas, 21 (48,8 %) fueron identificadas en el gen BRCA1 y 22 (51,2 %) en el gen BRCA2. Dentro de estas variantes, se identificaron 5 mutaciones patogénicas solo en el gen BRCA1, de las cuales solo una había sido reportada previamente en Colombia.Conclusiones: este estudio identifica variantes genéticas patogénicas en el gen BRCA1 no descritas en estudios previos en la población colombiana y otras conocidas en diferentes poblaciones; permitiendo de esta forma ampliar el conocimiento sobre las variantes en población colombiana de los genes BRCA1 y BRCA2. Sin embargo, se requieren más estudios con suficiente poder y calidad metodológica para poder estimar la frecuencia de mutaciones y de variantes de secuencia para estos genes en mujeres colombianas con sospecha de síndrome de cáncer de mama u ovario hereditario...

To describe sequence variants in the BRCA1 and BRCA2 genes in a sample of Colombian patients with a personal or family history of breast cancer suggestive of genetic risk.Materials and methods: Case series consisting of 67 patients referred for genetic testing because of suspected hereditary breast and ovarian cancer syndrome (HBOC). Of the 67 cases, 42 (62.7%) met the medical indication criteria of the 2013 National Comprehensive Cancer Network (NCCN) and they were subjected to the entire sequencing of the BRCA1 and BRCA2 genes. A determination was made of the frequency of sequence mutation, variants, and of the clinical significance of the variants found based on the Breast Cancer Information Core (BIC).Results: Mutations were identified for the BRCA 1 gene in six patients (14.3%), no mutation was documented for the BRCA 2 gene, and 43 genetic variants were found in 27 patients (64.2% of 42 cases). Of these, 21 (48.8%) were identified in the BRCA1 gene and 22 (51.2%) in the BRCA 2 gene. Among these variants, 5 pathogenic mutations were found only in the BRCA1 gene and, of those, only 1 had been reported previously in Colombia.Conclusions: This study identifies pathogenic genetic variants in the BRCA1 gene not described previously in the Colombian population, as well as others known in different populations. Therefore, it helps expand knowledge regarding the variants of the BRCA1 and BRCA2 genes in the Colombian population. However, additional studies are required with sufficient power and methodological quality to estimate the frequency of sequence mutations and variants for the BRCA1 and BRCA2 genes in Colombian women suspected of having the hereditary breast or ovarian cancer syndrome...
