Capture-based targeted sequencing using a T-cell control in myeloid malignancies and idiopathic cytopenias.

We report on a study of next-generation sequencing in 257 patients undergoing investigations for cytopenias. We sequenced bone marrow aspirates using a target enrichment panel comprising 82 genes and used T cells from paired blood as a control. One hundred and sixty patients had idiopathic cytopenias, 81 had myeloid malignancies and 16 had lymphoid malignancies or other diagnoses. Forty-seven of the 160 patients with idiopathic cytopenias had evidence of somatic pathogenic variants consistent with clonal cytopenias. Only 39 genes of the 82 tested were mutated in the 241 patients with either idiopathic cytopenias or myeloid neoplasms. We confirm that T cells can be used as a control to distinguish between germline and somatic variants. The use of paired analysis with a T-cell control significantly reduced the time molecular scientists spent reporting compared to unpaired analysis. We identified somatic variants of uncertain significance (VUS) in a higher proportion (24%) of patients with myeloid malignancies or clonal cytopenias compared to less than 2% of patients with non-clonal cytopenias. This suggests that somatic VUS are indicators of a clonal process. Lastly, we show that blood depleted of lymphocytes can be used in place of bone marrow as a source of material for sequencing.

Prediabetes remission after bariatric surgery: a 4-years follow-up study.

BACKGROUND: Bariatric surgery leads to weight loss and to cardiometabolic risk improvement. Although prediabetes remission after bariatric surgery is biologically plausible, data on this topic is scarce. We aimed to assess prediabetes remission rate and clinical predictors of remission in a 4 year follow up period. METHODS: Observational longitudinal study including patients with obesity and prediabetes who had undergone bariatric surgery in our centre. Prediabetes was defined as having a baseline glycated haemoglobin (A1c) between 5.7% and 6.4% and absence of anti-diabetic drug treatment. We used logistic regression models to evaluate the association between the predictors and prediabetes remission rate. RESULTS: A total of 669 patients were included, 84% being female. The population had a mean age of 45.4 ± 10.1 years-old, body mass index of 43.8 ± 5.7 kg/m2, and median A1c of 5.9 [5.8, 6.1]%. After bariatric surgery, prediabetes remission rate was 82%, 73%, 66%, and 58%, respectively in the 1st, 2nd, 3rd, and 4th years of follow-up. Gastric sleeve (GS) surgery was associated with higher prediabetes remission rate than Roux-en-Y gastric bypass surgery in the 3rd year of follow-up. Men had a higher remission rate than women, in the 1st and 3nd years of follow-up in the unadjusted analysis. Younger patients presented a higher remission rate comparing to older patients in the 3rd year of follow-up. CONCLUSION: We showed a high prediabetes remission rate after bariatric surgery. The remission rate decreases over the follow-up period, although most of the patients maintain the normoglycemia. Prediabetes remission seems to be more significant in patients who had undergone GS, in male and in younger patients.

COVID-19 Lockdown and Impact on 2-Year Weight Loss in a Bariatric Center.

INTRODUCTION: The COVID-19 pandemic has led to a worldwide lockdown, which affected physical exercise habits, as well as having a detrimental effect on psychological health and follow-up visits of patients submitted to bariatric surgery. The aim of this study was to evaluate the impact of COVID-19 lockdown on the 2-year weight loss of patients submitted to bariatric surgery in our center. METHODS: This was an observational study comparing the weight loss of patients who underwent bariatric surgery from January to March 2020 with a control group submitted to surgery between January and March 2017. Percentage of total weight loss (% TWL) and excess weight loss (% EWL) were assessed 6, 12, and 24 months after surgery. RESULTS: A total number of 203 patients were included in this study, 102 had bariatric surgery during the selected period in 2020 and 101 underwent surgery during the same period in 2017. There was no statistically significant difference in weight loss between the 2017 and 2020 groups which was reported as % TWL (mean 27.08 ± 7.530 vs. 28.03 ± 7.074, 33.87 ± 8.507 vs. 34.07 ± 8.979 and 34.13 ± 9.340 vs. 33.98 ± 9.993; p = 0.371) and % EWL (mean 66.83 ± 23.004 vs. 69.71 ± 17.021, 83.37 ± 24.059 vs. 84.51 ± 21.640 and 83.47 ± 24.130 vs. 84.27 ± 23.651; p = 0.506) at 6, 12, and 24 months post-surgery. CONCLUSION: Despite social limitations imposed by the COVID-19 lockdown, we found no significant difference between weight loss at 2 years postoperatively in the 2020 group when compared with a control group who underwent bariatric surgery in 2017. These results show that the outcomes of bariatric surgery during the COVID-19 lockdown were comparable with those recorded before the pandemic, supporting the efficacy of bariatric procedures' metabolic effects during the first 2 years after surgery, regardless of lifestyle habits.

Self-care guidelines for patients in the post-hematopoietic stem cell transplantation period: a scoping review.

OBJECTIVE: To map the evidence on self-care guidelines for patients in the post-hematopoietic stem cell transplantation (HSCT) period. METHOD: Scoping review supported by Joanna Briggs Institute recommendations, with searches conducted between March and April 2022 in national and international databases and repositories of theses and dissertations. RESULTS: Of the 11 studies that composed the final sample, the guidelines had a social and personal aspect, as post-transplant patients need to follow numerous essential recommendations for the prevention of infections and complications for successful treatment and improved quality of life. CONCLUSION: Knowing the self-care guidelines that must be performed by post-HSCT patients is fundamental for the nursing team to provide the necessary information for care outside the controlled environment of the hospital, in addition to minimizing episodes of infection, death, and increasing the survival and quality of life of transplant recipients.

Stromal Vascular Fraction Obtained From Subcutaneous Adipose Tissue: Ex-Obese and Older Population as Main Clinical Targets.

INTRODUCTION: Human adipose tissue contains a heterogeneous and synergistic mixture of cells called stromal vascular fraction (SVF) with highly proliferative and angiogenic properties, conferring promising applicability in the field of regenerative medicine. This study aims to investigate if age, body mass index (BMI), history of obesity and massive weight loss, and harvest site are related to SVF cell marker expression. METHODS: A total of 26 samples of subcutaneous adipose tissue were harvested from patients admitted to the Plastic and Reconstructive department in University Hospital Center of São João, Porto, Portugal, for body contouring surgery. The percentage of cells expressing CD31, CD34, CD45, CD73, CD90, and CD105 was assessed and compared with patient's age, BMI, history of obesity and massive weight loss (ex-obese group), and harvest site. RESULTS: In the ex-obese group, a significantly higher number of cells expressing CD90 (P = 0.002) was found. BMI, harvest site, and age appear to have no association with SVF subpopulations. CONCLUSIONS: This study suggests that ex-obese patients have a higher percentage of SVF cells expressing CD90, which correlates with higher proliferative and angiogenic rates. The effect of former obesity and massive weight loss on the expression of CD90 is a new and relevant finding because it makes this population a suitable candidate for reconstructive and aesthetic surgery and other fields of regenerative medicine. The use of SVF appears also promising in older patients because no negative correlation between increasing age and different cell markers expression was found.

Growth Factor-Free Vascularization of Marine-Origin Collagen Sponges Using Cryopreserved Stromal Vascular Fractions from Human Adipose Tissue.

The successful integration of transplanted three-dimensional tissue engineering (TE) constructs depends greatly on their rapid vascularization. Therefore, it is essential to address this vascularization issue in the initial design of constructs for perfused tissues. Two of the most important variables in this regard are scaffold composition and cell sourcing. Collagens with marine origins overcome some issues associated with mammal-derived collagen while maintaining their advantages in terms of biocompatibility. Concurrently, the freshly isolated stromal vascular fraction (SVF) of adipose tissue has been proposed as an advantageous cell fraction for vascularization purposes due to its highly angiogenic properties, allowing extrinsic angiogenic growth factor-free vascularization strategies for TE applications. In this study, we aimed at understanding whether marine collagen 3D matrices could support cryopreserved human SVF in maintaining intrinsic angiogenic properties observed for fresh SVF. For this, cryopreserved human SVF was seeded on blue shark collagen sponges and cultured up to 7 days in a basal medium. The secretome profile of several angiogenesis-related factors was studied throughout culture times and correlated with the expression pattern of CD31 and CD146, which showed the formation of a prevascular network. Upon in ovo implantation, increased vessel recruitment was observed in prevascularized sponges when compared with sponges without SVF cells. Immunohistochemistry for CD31 demonstrated the improved integration of prevascularized sponges within chick chorioalantoic membrane (CAM) tissues, while in situ hybridization showed human cells lining blood vessels. These results demonstrate the potential of using cryopreserved SVF combined with marine collagen as a streamlined approach to improve the vascularization of TE constructs.

[Pre-Exposure Prophylaxis for Human Immunodeficiency Virus in the Medical Curricula in Portugal: A Cross-Sectional Analysis].

INTRODUCTION: Pre-exposure prophylaxis (PrEP) has gained relevance as a method of prevention for HIV in certain people and settings. Following the publication of the guideline on PrEP prescribing in Portugal, we aimed to assess the knowledge of Portuguese Medical Students about PrEP. MATERIAL AND METHODS: An online survey was sent to Medical students of Portuguese Medical Schools. We conducted a descriptive analysis of the results and an analytic cross-sectional study to identify factors associated with "knowing about PrEP", "having had one class about PrEP" and "identifying eligible groups correctly". RESULTS: Of the 796 students that responded to the survey, 64.6% were aware of what PrEP is. Of these, 34.44% acquired this knowledge during their training. Out of the total amount of respondents, 4.77% could identify correctly and completely the eligible groups for PrEP. As the training years went by, the probability of being aware of PrEP, having had one class about PrEP, and identifying the eligible groups correctly, increased. Of the sixth-year students, 43.48% had had one class about PrEP and among the students that were aware of PrEP, 28% identified what the eligible groups were. After adjusting for the school year, we found differences between Medical Schools regarding the outcomes. The association between the different ways of learning about PrEP and the ability to correctly identify eligible groups for PrEP was not statistically significant. CONCLUSION: The differences between Medical Schools could be harmonized through changes in the medical curricula that would allow this topic to be addressed more often.

Introdução: A profilaxia pré-exposição (PrEP) ganhou relevância como método de prevenção do VIH em determinados indivíduos e contextos. Após a entrada em vigor das normas para prescrição em Portugal, pretendemos aferir o conhecimento em relação à PrEP entre os estudantes de Medicina em Portugal.Material e Métodos: Foi enviado um questionário online aos estudantes de Medicina das escolas médicas portuguesas. Foi feita uma análise descritiva dos resultados e um estudo transversal analítico para identificar fatores associados a "conhecer a PrEP", "ter tido uma aula de PrEP", e "identificar grupos elegíveis corretamente".Resultados: Dos 796 estudantes que responderam, 64,6% sabiam o que era a PrEP. Destes, 34,44% obteve conhecimento sobre a mesma durante a sua formação. Entre os respondentes, 4,77% identificaram correta e completamente os grupos elegíveis. Com o avançar do ano letivo, a probabilidade de conhecer a PrEP, ter tido uma aula de PrEP e identificar os grupos corretamente aumentava. No sexto ano, 43,48% tinham tido uma aula sobre PrEP e entre os que conheciam a PrEP, 28% identificaram os grupos elegíveis. Existem diferenças entre as escolas médicas após ajustamento para o ano letivo em relação aos resultados obtidos. A forma como se tomou conhecimento da PrEP não alterou de forma estatisticamente significativa a capacidade de identificar corretamente grupos elegíveisConclusão: As diferenças entre as escolas médicas poderão ser harmonizadas. Esta temática poderá ser reforçada nos respetivos currículos.

Saúde mental, arte e desinstitucionalização: um relato estético-poético-teatral de uma ocupação da cidade / Mental health, art, and deinstitutionalization: an aesthetic-poetic-theatrical account of the city's occupation

Resumo Objetivou-se relatar a experiência de uma produção estética, poética e teatral de ocupação da cidade a partir de um dispositivo da Rede de Atenção Psicossocial, com vistas a oferecer espaço de sociabilidade, produção e intervenção cultural. Trata-se de um relato de experiência a partir do Centro de Convivência e Cultura (CECCO) de Natal, Rio Grande do Norte, Brasil, dentro do campo da desinstitucionalização da loucura e da saúde mental. A intervenção urbana "O Pequeno Príncipe ocupa a Ribeira" foi inspirada na obra do escritor Saint-Exupéry. Os atos artísticos e criativos relatados aconteceram em dezembro de 2019. Experimentamos nessa intervenção os alcances de uma clínica-estética que, ao se abrir para a rua e para a arte, se amplia e se tece no território, instrumentalizado pelo teatro, dança, poesia, percussão, artesanato e ocupação da cidade. O movimento gerou no coletivo um "descer do palco" em direção à rua e se conecta com a desconstrução do modelo manicomial e produção da clínica dos afetos que buscamos sustentar no cotidiano do serviço.

Abstract This study aimed to report the experience of an aesthetic, poetic, and theatrical production of the city's occupation from a device of the Psychosocial Care Network to offer space for sociability, production, and cultural intervention. This is an account of an experience from the Social and Cultural Center (CECCO) in Natal, Rio Grande do Norte, Brazil, within madness and mental health deinstitutionalization. The intervention "The Little Prince occupies the Ribeira" was inspired by the work of author Saint-Exupéry. The artistic and creative acts reported occurred in December 2019. We experienced in this intervention the reach of an aesthetic clinic that, when opened to the street and art, expanded and weaved in the territory, instrumentalized by theater, dance, poetry, percussion, crafts, and city's occupation. The movement led the community to "step down from the stage" to the streets and is connected with the twist of the asylum model and the production of the affection clinic that we seek to sustain in the daily service.

Genomic Abnormalities as Biomarkers and Therapeutic Targets in Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is a highly heterogeneous malignancy characterized by the clonal expansion of myeloid stem and progenitor cells in the bone marrow, peripheral blood, and other tissues. AML results from the acquisition of gene mutations or chromosomal abnormalities that induce proliferation or block differentiation of hematopoietic progenitors. A combination of cytogenetic profiling and gene mutation analyses are essential for the proper diagnosis, classification, prognosis, and treatment of AML. In the present review, we provide a summary of genomic abnormalities in AML that have emerged as both markers of disease and therapeutic targets. We discuss the abnormalities of RARA, FLT3, BCL2, IDH1, and IDH2, their significance as therapeutic targets in AML, and how various mechanisms cause resistance to the currently FDA-approved inhibitors. We also discuss the limitations of current genomic approaches for producing a comprehensive picture of the activated signaling pathways at diagnosis or at relapse in AML patients, and how innovative technologies combining genomic and functional methods will improve the discovery of novel therapeutic targets in AML. The ultimate goal is to optimize a personalized medicine approach for AML patients and possibly those with other types of cancers.

Predictors associated with sickle cell nephropathy: a systematic review

SUMMARY INTRODUCTION: Sickle cell anemia affects more than 30 million people worldwide. Chronic kidney disease develops in 40% of individuals. The death rate of patients with sickle nephropathy is still high, with little known predictors related to its development. To answer the question "What predictors are associated with the onset of chronic kidney disease in patients with sickle cell anemia?", this article seeks to contribute to a better understanding of sickle nephropathy, making possible a new look at the sickle cell anemia and its kidney complications. METHODS: A systematic review was developed, using the PRISMA recommendation, for cohort studies on predictors related to the outcome of sickle nephropathy in patients with sickle cell anemia. RESULTS: Initially 321 studies were identified in Pubmed, of which six were selected to compose this systematic review. Lower hemoglobin levels, increased ages and albuminuria were the most pointed predictors associated with chronic kidney disease. CONCLUSION: The main predictors associated with the development of chronic kidney disease in individuals with sickle cell anemia were lower hemoglobin levels, increased ages, and albuminuria. New studies evaluating predictors for the development of chronic kidney disease in sickle cell anemia are needed to better understand its installation and prevent its progression.

Oral leukoplakia-epidemiological survey and histochemical analysis of 107 cases in Brazil.

OBJECTIVE: To perform an epidemiological survey comparing the cell proliferative activity of 107 cases of oral leukoplakia with their clinical and histopathological characteristics. MATERIALS AND METHODS: A cross-sectional, observational, and histological-histochemical study. The cases came from the Histopathological Diagnostic Service of UPF/RS and the School of Dentistry of Araçatuba FOA/UNESP/SP (1986-2016). The histopathological sections were stained using the silver staining (AgNOR) technique and the nuclei of 100 epithelial cells selected randomly were recorded to count the number of nucleolar organizer regions (NORs). The mean NORs per lesion were correlated to clinical and histological characteristics using ANOVA, at 5% significance. RESULTS: Most of the cases included men (62.62%), white (64.49%), and with an average age of 53.94 years. The most probable etiological factors were smoking (44.7%) and alcohol consumption (9.85%). The evolution time of most lesions was fast (33.65%), manifesting mainly in the form of plaques (70.37%) and without symptoms (58.88%). They were located mainly in the cheek mucosa (26.62%) and presented white color (66.35%), well-defined edges (59.81%), firm consistency (47.5%), and keratinized surface (49.53%). Etiological factor (p = 0.003), evolution time (p = 0.006), symptoms (p = 0.029), location (p = 0.020), consistency (p = 0.047), histopathological characteristics (p = 0.004), and superficial keratinization (p = 0.001) were statistically significant regarding the mean NORs of the leukoplakias studied. CLINICAL RELEVANCE: Oral leukoplakias caused by alcohol consumption and/or tobacco use, considering an evolution time of fewer than 12 months, asymptomatic, located in the lower lip or tongue, and with a firm consistency and increased superficial keratinization should be treated more aggressively by the clinician to avoid cancerization.

Histopathological Classifications of Oral Leukoplakia and its Relation to Cell Proliferative Activity: A Case Series.

AIM: This study relates the average number of nucleolar organizing regions (NORs) obtained in a series of cases of oral leukoplakia, with three methods of histopathological classification of such lesion. MATERIALS AND METHODS: This is a histopathological-histochemical laboratory cross-sectional study. The 18 cases of leukoplakia analyzed were filed at Pathology Service of the Biological Sciences Institute of the University of Passo Fundo, Rio Grande do Sul, Brazil (SDH/ICB/UPF) (2017 and 2018), from which epidemiological data were extracted. New histological sections were performed for impregnation by the argyrophilic nucleolar organizer regions (AgNOR) technique. The histopathological slides were analyzed by photon microscopy (1,000×), and the nuclei of 100 epithelial cells were photographed to count the number of NORs. Three methods were used for the lesions' histopathological classification [World Health Organization (WHO), Brothwell, and binary system]. The means of NORs were compared with the three histopathological classifications by means of the t or analysis of variance (ANOVA) statistical tests, at a significance level of 5%. RESULTS: According to the WHO classification method, most cases (11-61.1%) had a moderate classification. Evaluations by the Brothwell method showed moderate and mild classification in 50 and 38.9% of cases, respectively. According to the binary system, most cases (10-55.6%) had low risk. The average NORs found in 100 nuclei of each of the 18 lesions ranged from 2 to 4. When crossing the average NORs with the histopathological classification methods of the lesions by means of the t test or ANOVA, no significant relationship was noted. CONCLUSION: The average of NORs is not associated with the histological classifications of leukoplakias. Thus, the AgNOR method should be used with caution when differentiating different histological grades of leukoplakias. CLINICAL SIGNIFICANCE: The AgNOR method should be used with caution to determine the clinical treatment of oral leukoplakias, since no agreement was observed between this method and the histopathological classifications available for such lesion.

Predictors of pathological response and clinical outcome following chemoradiation for locally advanced rectal cancer - a systematic review / Preditores de resposta patológica e de outcome clinico após quimioradioterapia neoadjuvante para cancro do reto localmente avançado - uma revisão sistemática

Abstract Background: Colorectal cancer is one of the most common types of cancer and is associated with a high lethality rate. Treatment is multidisciplinary, and neoadjuvant chemoradiation is recommended in locally advanced rectal cancer. About 15% of patients answer favorably to neoadjuvant chemoradiation, so it is important to determine the predictors of response. Objective: To review the results of studies that analyzes the predictors of complete pathological response to neoadjuvant chemoradiation in patients with locally advanced rectal cancer. Search methods: We searched for eligible articles in data bases Pubmed and Scopus, between the 12th and the 20th of March 2020. The following key words were used: "predictors of response", "chemoradiation" and "locally advanced rectal cancer". Selection criteria: Inclusion criteria: Studies including patients with locally advanced rectal cancer, patients receiving neoadjuvant chemoradiation as treatment, studies including predictors of response to neodjuvant chemoradiation, overall survival as an outcome and regarding language restrictions, only articles in English were accepted, only studies published until the 31st of December 2019 were accepted. Main results: Fourteen studies fulfilled the inclusion criteria. Thirteen are cohort studies and one is a clinical trial. Four groups of predictors were defined: blood markers, tumors, histopathological and patients' characteristics. Author's conclusions: During the analysis of the articles, there were several predictors identified as potential candidates for clinical practice, such as high pre neoadjuvant chemoradiation Carcinoembryonic Antigen levels and small post neoadjuvant chemoradiation tumor size. Nevertheless, it is difficult to make definitive conclusions about the most reliable predictors. That is why it is crucial to initiate further studies with standardized cut-off values and a methodology homogenization.

Resumo Introdução: O cancro colorretal é um dos cancros mais prevalentes em Portugal e tem associada uma alta taxa de letalidade. Atualmente, o tratamento é multidisciplinar, e a quimioradioterapia neoadjuvante está indicada no Cancro do Reto Localmente Avançado. Sabe-se que cerca de 15% dos doentes responde favoravelmente à quimioradioterapia neoadjuvante, sendo por isso importante determinar quais os preditores de resposta a este tipo de tratamento. Objetivo: Rever os resultados dos estudos que analisam os preditores de resposta completa à quimioradioterapia em pacientes com Cancro do Reto Localmente Avançado. Métodos de pesquisa: Pesquisamos artigos elegíveis nos bancos de dados Pubmed e Scopus, desde o dia 12 a 20 de Março de 2020. Foram utilizadas as seguintes palavras chave: "preditores de resposta", "quimioradioterapia neoadjuvante" e "Cancro do Reto Localmente Avançado". Critérios de seleção: Critérios de inclusão: Estudos que incluam pacientes com Cancro do Reto Localmente Avançad, pacientes sujeitos a quimioradioterapia neoadjuvante, preditores de resposta à quimioradioterapia, que avaliem a sobrevivência como outcome, escritos em inglês e publicados até dia 31 de Dezembro de 2019. Resultados principais: Catorze estudos preencheram os critérios de inclusão. De todos os artigos, treze são Cohort e um é Clinical Trial. Foram definidos quatro grupos de preditores: marcadores de sangue e caraterísticas do tumor, histopatológicas e dos pacientes. Conclusões dos autores: Durante a análise dos artigos, foram identificados vários preditores como potenciais candidates para a prática clínica, tais como o valor elevado de antigénio carcinoembrionário pré- quimioradioneoaajuvância e tamanho reduzido. Contudo, é arriscado elaborar conclusões concretas relativamente aos preditores mais confiáveis. Por isso, é crucial iniciar novos estudos com valores de cut-off estandardizados e métodos com maior homogeneidade.

Outcomes Comparison Between Wavefront-Optimized and Topography-Guided PRK in Contralateral Eyes With Myopia and Myopic Astigmatism.

PURPOSE: To compare clinical outcomes between topography-guided customized ablation treatment (TCAT) and wavefront-optimized (WFO) photorefractive keratectomy (PRK) in fellow eyes of myopic patients. METHODS: Forty-six eyes of 23 patients who underwent PRK were included. WFO ablation was performed in one eye (WFO group) and TCAT in the fellow eye (TCAT group). The customized treatment plan was based on the Topolyzer Vario topography system (Alcon Laboratories, Inc) data. The patients were observed for 12 months after the procedure. RESULTS: One year after the surgery, there was no significant difference in the manifest refraction spherical equivalent, sphere, or cylinder variables between the two groups (P > .05). In both groups, 96% of eyes achieved an uncorrected distance visual acuity of 20/20 or better at 12 months postoperatively. Accuracy, safety, and efficacy of the refractive and visual outcomes were similar in the two groups. The postoperative higher order aberrations magnitude was lower in the TCAT group, but this was not statistically significant (P > .05). During the 12-month follow-up, no patient described any symptoms related to glare, halos, or starbursts in either eye. Other postoperative complications, such as infection or cor-neal infiltrates, did not occur in either group. CONCLUSIONS: TCAT and WFO ablations provided similar outcomes after PRK for myopia and myopic astigmatism correction. There were no statistically significant differences in postoperative corneal wavefront analysis. [J Refract Surg. 2020;36(6):358-365.].
