Retinoic Acid-Mediated Control of Energy Metabolism Is Essential for Lung Branching Morphogenesis.

Lung branching morphogenesis relies on intricate epithelial-mesenchymal interactions and signaling networks. Still, the interplay between signaling and energy metabolism in shaping embryonic lung development remains unexplored. Retinoic acid (RA) signaling influences lung proximal-distal patterning and branching morphogenesis, but its role as a metabolic modulator is unknown. Hence, this study investigates how RA signaling affects the metabolic profile of lung branching. We performed ex vivo lung explant culture of embryonic chicken lungs treated with DMSO, 1 µM RA, or 10 µM BMS493. Extracellular metabolite consumption/production was evaluated by using 1H-NMR spectroscopy. Mitochondrial respiration and biogenesis were also analyzed. Proliferation was assessed using an EdU-based assay. The expression of crucial metabolic/signaling components was examined through Western blot, qPCR, and in situ hybridization. RA signaling stimulation redirects glucose towards pyruvate and succinate production rather than to alanine or lactate. Inhibition of RA signaling reduces lung branching, resulting in a cystic-like phenotype while promoting mitochondrial function. Here, RA signaling emerges as a regulator of tissue proliferation and lactate dehydrogenase expression. Furthermore, RA governs fatty acid metabolism through an AMPK-dependent mechanism. These findings underscore RA's pivotal role in shaping lung metabolism during branching morphogenesis, contributing to our understanding of lung development and cystic-related lung disorders.

Hyperbaric Oxygen Therapy in Upper Limb Crush Injury: Why and When?

Introduction In 2016, the European Committee for Hyperbaric Medicine strongly recommended hyperbaric oxygen therapy (HBOT) adjunctive to surgery in post-traumatic crush injuries, initiating as rapidly as possible. For the last 30 years, HBOT has been used in crush injury, but in most cases as a last resort, after skin flaps necrosis or wound bed infection, diminishing its potential benefits as a complementary treatment. It is, therefore, essential to understand how HBOT modulates the outcome of crush injury, and when to use it, since this can be a significant and underused therapeutic weapon that may alter the natural course of these patients. Methods Nineteen (n=19) adult patients with upper limb crush injuries underwent adjunctive HBOT, after the initial surgical approach. The measured outcomes included trauma-related acute complications (tissue necrosis and local infection), and late complications (pseudarthrosis and late deep infection). Results Only six (n=6) patients started HBOT in the first 24 hours. Four (n=4) patients presented acute complications; in half of those cases (n=2), HBOT was initiated more than 24 hours post-injury. Late complications were observed in three patients, none of which had initiated HBOT in the first 24 hours post-injury. Conclusions Either lack of awareness or logistic difficulties, preclude initiating timely HBOT, limiting its potential benefits. It is important to alert all practitioners to the right timing to initiate HBOT in order to improve these patients' outcomes.

Bibliometric analysis of global research trends on biomimetics, biomimicry, bionics, and bio-inspired concepts in civil engineering using the Scopus database.

Survival After Hematopoietic Stem Cell Transplantation in Severe Combined Immunodeficiency (SCID): A Worldwide Review of the Prognostic Variables.

This study aims to perform an extensive review of the literature that evaluates various factors that affect the survival rates of patients with severe combined immunodeficiency (SCID) after hematopoietic stem cell transplantation (HSCT) in developed and developing countries. An extensive search of the literature was made in four different databases (PubMed, Embase, Scopus, and Web of Science). The search was carried out in December 2022 and updated in July 2023, and the terms such as "hematopoietic stem cell transplantation," "bone marrow transplant," "mortality," "opportunistic infections," and "survival" associated with "severe combined immunodeficiency" were sought based on the MeSH terms. The language of the articles was "English," and only articles published from 2000 onwards were selected. Twenty-three articles fulfilled the inclusion criteria for review and data extraction. The data collected corroborates that early HSCT, but above all, HSCT in patients without active infections, is related to better overall survival. The universal implementation of newborn screening for SCID will be a fundamental pillar for enabling most transplants to be carried out in this "ideal scenario" at an early age and free from infection. HSCT with an HLA-identical sibling donor is also associated with better survival rates, but this is the least common scenario. For this reason, transplantation with matched unrelated donors (MUD) and mismatched related donors (mMRD/Haploidentical) appear as alternatives. The results obtained with MUD are improving and show survival rates similar to those of MSD, as well as they do not require manipulation of the graft with expensive technologies. However, they still have high rates of complications after HSCT. Transplants with mMRD/Haplo are performed just in a few large centers because of the high costs of the technology to perform CD3/CD19 depletion and TCRαß/CD19 depletion or CD34 + selection techniques in vitro. The new possibility of in vivo T cell depletion using post-transplant cyclophosphamide could also be a viable alternative for performing mMRD transplants in centers that do not have this technology, especially in developing countries.

Automatic multi-view pose estimation in focused cardiac ultrasound.

Focused cardiac ultrasound (FoCUS) is a valuable point-of-care method for evaluating cardiovascular structures and function, but its scope is limited by equipment and operator's experience, resulting in primarily qualitative 2D exams. This study presents a novel framework to automatically estimate the 3D spatial relationship between standard FoCUS views. The proposed framework uses a multi-view U-Net-like fully convolutional neural network to regress line-based heatmaps representing the most likely areas of intersection between input images. The lines that best fit the regressed heatmaps are then extracted, and a system of nonlinear equations based on the intersection between view triplets is created and solved to determine the relative 3D pose between all input images. The feasibility and accuracy of the proposed pipeline were validated using a novel realistic in silico FoCUS dataset, demonstrating promising results. Interestingly, as shown in preliminary experiments, the estimation of the 2D images' relative poses enables the application of 3D image analysis methods and paves the way for 3D quantitative assessments in FoCUS examinations.

Impact of polyurethane versus acellular dermal matrix coating on prepectoral reconstruction outcomes: Interface does matter.

BACKGROUND: Interfaces continue to be used in prepectoral breast reconstruction to refine breast appearance, but more clinical data are required to assess their effectiveness. This study compares the rates of capsular contracture, breast esthetics, and patient satisfaction between two commonly used interface materials, acellular dermal matrix (ADM) and polyurethane (PU) foam. METHODS: A cross-sectional assessment was conducted on all patients who underwent prepectoral direct-to-implant reconstruction with an interface material between June 2018 and June 2022. We compared capsular contracture rates (assessed in-person), esthetic outcomes (evaluated by a three-member panel using a specially designed scale), and patient satisfaction (measured using the Breast-Q questionnaire) among the members of the interface groups. RESULTS: Among the 79 reconstructed breasts (20 bilateral cases), 35 were reconstructed using ADM and 44 using PU implants. The ADM group had a significantly higher frequency of Baker III/IV capsular contracture compared with the PU group (14.3% vs. 0%, p = 0.014) and lower ratings from the panel in terms of capsular contracture (median 3.7 vs. 4.0, p < 0.001). PU reconstructions scored worse in implant visibility (median 2.3 vs. 3.3, p < 0.001) and rippling (median 3.0 vs. 3.7, p < 0.001). However, after appropriate adjustment for confounders, no significant differences in overall appearance and patient satisfaction were found. CONCLUSIONS: ADM reconstructions are prone to capsular contracture with all their related esthetic issues, but PU implants have certain cosmetic flaws, such as implant visibility and malposition. Since each technique has its own limitations, neither the experienced surgeons nor patients exhibited a clear preference for either approach.

Heterotopic ossification - A rare donor site complication after iliac crest free flap.

Iliac crest free flap is still essential as a source of vascularized bone tissue, having a definite role in osseous reconstruction of the face and other small bone defects. Some of its drawbacks include laborious dissection and donor site morbidity. We report a case of a patient that presented to our follow-up consultation ten years after iliac crest free flap harvest with new complaints of pain, gait disturbance and swelling in the right hip. Imaging exams revealed a heterotopic bone formation and helped with the diagnosis of heterotopic ossification (HO) of the right iliacus bone. Surgical intervention was needed for debridement of the heterotopic bone, with resolution of the symptoms. To our knowledge, this is the first report of HO after iliac crest free flap harvest. This rare condition adds to an already well-known number of donor zone complications of this flap. Plastic surgeons should be aware of this complication, as it can cause disability many years after the original surgery.

Efecto de la interrupción en la conducta sedentaria sobre el control glicémico en la diabetes gestacional

La actividad física produce efectos benéficos en la mujer embarazada; a pesar de ello, la mayoría presentan altos niveles de conducta sedentaria. El objetivo del estudio fue evidenciar el efecto del quiebre en la conducta sedentaria sobre el control metabólico en una paciente de 36 años con diabetes gestacional. La intervención consistió en reorganizar su rutina diaria y realizar un protocolo de quiebre en la conducta sedentaria. La paciente logró un control metabólico óptimo luego del comienzo de la intervención y hasta el final del embarazo. El protocolo de quiebre en la conducta sedentaria sumado a la reorganización en la rutina de la paciente resultó ser efectivo para lograr el control glicémico y evitar complicaciones propias asociadas a la diabetes gestacional.

Physical activity produces beneficial effects in pregnant women. In spite of this, most of them present high levels of sedentary behavior. The objective of the study was to demonstrate the effect of a break in sedentary behavior on metabolic control in a 36-year-old patient with gestational diabetes. The intervention consisted of reorganizing her daily routine and performing a sedentary behavior break protocol. The patient achieved optimal metabolic control after the beginning of the intervention and until the end of pregnancy. The sedentary behavior break protocol added to the reorganization of the patient's routine proved to be effective in achieving glycemic control and avoiding complications associated with gestational diabetes.

Diretrizes brasileiras do angioedema hereditário 2022 ­ Parte 1: definição, classificação e diagnóstico / 2022 Brazilian guidelines for hereditary angioedema ­ Part 1: definition, classification, and diagnosis

O angioedema hereditário é uma doença autossômica dominante caracterizada por crises recorrentes de edema que acometem o tecido subcutâneo e o submucoso, com envolvimento de diversos órgãos. Os principais locais afetados são face, membros superiores e inferiores, as alças intestinais e as vias respiratórias superiores. Em decorrência da falta de conhecimento dessa condição por profissionais de saúde, ocorre atraso importante no seu diagnóstico, comprometendo a qualidade de vida dos indivíduos afetados. Além disso, o retardo no diagnóstico pode resultar em aumento da mortalidade por asfixia devido ao edema de laringe. A natureza errática das crises com variação do quadro clínico e gravidade dos sintomas entre diferentes pacientes, e no mesmo paciente ao longo da vida, se constitui em desafio no cuidado dos doentes que têm angioedema hereditário. O principal tipo de angioedema hereditário é resultante de mais de 700 variantes patogênicas do gene SERPING1 com deficiência funcional ou quantitativa da proteína inibidor de C1, porém nos últimos anos outras mutações foram descritas em seis outros genes. Ocorreram avanços importantes na fisiopatologia da doença e novas drogas para o tratamento do angioedema hereditário foram desenvolvidas. Nesse contexto, o Grupo de Estudos Brasileiro em Angioedema Hereditário (GEBRAEH) em conjunto com a Associação Brasileira de Alergia e Imunologia (ASBAI) atualizou as diretrizes brasileiras do angioedema hereditário. O maior conhecimento dos diversos aspectos resultou na divisão das diretrizes em duas partes, sendo nessa primeira parte abordados a definição, a classificação e o diagnóstico.

Hereditary angioedema is an autosomal dominant disease characterized by recurrent attacks of edema that affect the subcutaneous tissue and the submucosa, involving several organs. The main affected sites are the face, upper and lower limbs, gastrointestinal tract, and upper airways. Because health professionals lack knowledge about this condition, there is a significant delay in diagnosis, compromising the quality of life of affected individuals. Furthermore, delayed diagnosis may result in increased mortality from asphyxia due to laryngeal edema. The erratic nature of the attacks with variations in clinical course and severity of symptoms among different patients and in one patient throughout life constitutes a challenge in the care of patients with hereditary angioedema. The main type of hereditary angioedema results from more than 700 pathogenic variants of the SERPING1 gene with functional or quantitative deficiency of the C1 inhibitor protein, but in recent years other mutations have been described in six other genes. Important advances have been made in the pathophysiology of the disease, and new drugs for the treatment of hereditary angioedema have been developed. In this context, the Brazilian Study Group on Hereditary Angioedema (GEBRAEH) in conjunction with the Brazilian Association of Allergy and Immunology (ASBAI) updated the Brazilian guidelines on hereditary angioedema. Greater knowledge of different aspects resulted in the division of the guidelines into two parts, with definition, classification, and diagnosis being addressed in this first part.

Diretrizes brasileiras de angioedema hereditário 2022 ­ Parte 2: terapêutica / 2022 Brazilian guidelines for hereditary angioedema ­ Part 2: therapy

O tratamento do angioedema hereditário tem início com a educação dos pacientes e familiares sobre a doença, pois é fundamental o conhecimento da imprevisibilidade das crises, assim como os seus fatores desencadeantes. O tratamento medicamentoso se divide em terapia das crises e profilaxia das manifestações clínicas. As crises devem ser tratadas o mais precocemente possível com o uso do antagonista do receptor de bradicinina, o icatibanto ou o concentrado de C1-inibidor. É necessário estabeler um plano de ação em caso de crises para todos os pacientes. A profilaxia de longo prazo dos sintomas deve ser realizada preferencialmente com medicamentos de primeira linha, como concentrado do C1-inibidor ou o anticorpo monoclonal anti-calicreína, lanadelumabe. Como segunda linha de tratamento temos os andrógenos atenuados. Na profilaxia de curto prazo, antes de procedimentos que podem desencadear crises, o uso do concentrado de C1-inibidor é preconizado. Existem algumas restrições para uso desses tratamentos em crianças e gestantes que devem ser consideradas. Novos medicamentos baseados nos avanços do conhecimento da fisiopatologia do angioedema hereditário estão em desenvolvimento, devendo melhorar a qualidade de vida dos pacientes. O uso de ferramentas padronizadas para monitorização da qualidade de vida, do controle e da atividade da doença são fundamentais no acompanhamento destes pacientes. A criação de associações de pacientes e familiares de pacientes com angioedema hereditário tem desempenhado um papel muito importante no cuidado destes pacientes no nosso país.

The treatment of hereditary angioedema begins with the education of patients and their families about the disease, as it is essential to know the unpredictability of attacks as well as their triggering factors. Drug treatment is divided into attack therapy and prophylaxis of clinical manifestations. Attacks should be treated as early as possible with the bradykinin receptor antagonist icatibant or C1-inhibitor concentrate. An action plan needs to be established for all patients with attacks. Long-term prophylaxis of symptoms should preferably be performed with first-line drugs such as C1-inhibitor concentrate or the anti-kallikrein monoclonal antibody lanadelumab. Attenuated androgens are the second line of treatment. In short-term prophylaxis, before procedures that can trigger attacks, the use of C1-inhibitor concentrate is recommended. There are some restrictions for the use of these treatments in children and pregnant women that should be considered. New drugs based on advances in knowledge of the pathophysiology of hereditary angioedema are under development and are expected to improve patient quality of life. The use of standardized tools for monitoring quality of life and controlling disease activity is essential in the follow-up of these patients. The creation of associations of patients and families of patients with hereditary angioedema has played a very important role in the care of these patients in Brazil.

Inguinal hernia in southern Brazil - challenges in follow-up and recurrence rates / Hérnia inguinal no Sul do Brasil - desafios no seguimento e taxas de recorrência

ABSTRACT Introduction: recurrence rates for primary hernia repair range from 0.5 to 15 percent depending upon the hernia site, type of repair, and clinical circumstances. Many risk factors are known and they must be considered before the procedure. In developing countries, follow up and maintenance of databases are critical to understand the real numbers. Methods: a retrospective cohort study analyzed adult patients who have undergone inguinal hernia repair at Hospital de Clínicas de Porto Alegre, a tertiary care government public hospital, between 2013 and 2015. Medical records, telephone, and letter contact have been reviewed in order to complete the minimum period of 5 years of follow-up. The analyzed data focused on the surgeon's experience and the recurrence rate in 5 years of follow-up. Results: a total of 1094 medical records were selected and a complete five years follow-up were possible in 454 patients - 538 inguinal hernia repairs due to bilateral approach in 84 patients. These 454 patients answered, in a validated questionnaire about symptoms of recurrence. The total recurrence rate was 9.29%. For the patients who had Nyhus IV, recurrence rate was 24.1% against 9.9% after primary hernia repair, with a 2.4 higher risk. There was no difference in recurrence between surgeons and training surgeons. Conclusion: our data reveal an acceptable recurrence rate in a tertiary care hospital with residents, and to our knowledge is the first Brazilian report with long term follow up. An increased re-recurrent hernia was found when compared with primary hernia repair.

RESUMO Introdução: a recorrência da hérnia inguinal após hernioplastia varia de 0,5 a 15 por cento, dependendo do local da hérnia, tipo de reparo e circunstâncias clínicas. Muitos fatores de risco são conhecidos e devem ser considerados antes do procedimento. Acompanhamento e adequado bancos de dados são fundamentais para entender a incidência de recidiva. Métodos: estudo de coorte retrospectivo analisou hernioplastias inguinais realizados no Hospital de Clínicas de Porto Alegre entre 2013 e 2015. Para concluir 5 anos de seguimento, analisamos o prontuário e fizemos contato telefônico e por correio. Resultados: o total de 1094 registros médicos foram selecionados e um seguimento de pelo menos 5 anos foi possível em 454 pacientes - 538 reparos de hérnia inguinal devido à abordagem bilateral em 84 pacientes. Os pacientes responderam um questionário validado sobre sintomas de recorrência. A taxa total de recorrência foi de 9,29%. No grupo masculino, a recorrência foi de 10% contra 4% no grupo feminino. Para os pacientes com hérnia Nyhus IV, a recidiva foi de 24% contra 8% após o reparo da hérnia primária, com um risco de 2,8 maior. Não houve diferença na recorrência entre cirurgiões experientes e em treinamento. Conclusão: nossos dados revelam uma taxa de recorrência aceitável em um hospital de ensino, e para o nosso conhecimento é o primeiro artigo com acompanhamento de longo prazo no sul do Brasil. A re-recidiva da hérnia foi maior quando comparada com o reparo da hérnia primária.

New proteasome inhibitors in the treatment of multiple myeloma

Abstract The treatment of patients with relapsed and/or refractory multiple myeloma has improved considerably in the last 15 years, after the introduction of proteasome inhibitors and immunomodulatory drugs. The first clinical trials with new proteasome inhibitors have produced exciting results, particularly those comparing triplet regimens with standard doublet regimens, with a gain in progression-free survival accompanied by an acceptable safety profile and either similar or better health-related quality of life. New proteasome inhibitors hold the potential to fill unmet needs in multiple myeloma management regarding improvement of clinical outcomes, including delayed progression of disease in high-risk patients. This review summarizes the main pharmacological properties and clinical outcomes of these agents, and discusses their potential to change the whole multiple myeloma therapeutic landscape.

Strong sex bias in elite control of paediatric HIV infection

BACKGROUND: Reports of posttreatment control following antiretroviral therapy (ART) have prompted the question of how common immune control of HIV infection is in the absence of ART. In contrast to adult infection, where elite controllers have been very well characterized and constitute approximately 0.5% of infections, very few data exist to address this question in paediatric infection. METHODS: We describe 11 ART-naive elite controllers from 10 cohorts of HIV-infected children being followed in South Africa, Brazil, Thailand, and Europe. RESULT: All but one of the elite controllers (91%) are females. The median age at which control of viraemia was achieved was 6.5 years. Five of these 11 (46%) children lost control of viraemia at a median age of 12.9 years. Children who maintained control of viraemia had significantly higher absolute CD4þ cell counts in the period of elite control than those who lost viraemic control. On the basis of data available from these cohorts, the prevalence of elite controllers in paediatric infection is estimated to be 5­10-fold lower than in adults. CONCLUSION: Although conclusions are limited by the study design, these data suggest that, whilst paediatric elite control can be achieved, compared with adult elite controllers, this occurs rarely, and takes some years after infection to achieve. Also, loss of immune control arises in a high proportion of children and often relatively rapidly. These findings are consistent with the more potent antiviral immune responses observed in adults and in females

Repetições máximas e tempo sob tensão entre as ordens multiarticular para monoarticular e monoarticular para multiarticular em exercícios resistidos / Repeticiones máximas y tiempo de tensión entre los ordenes multiarticular para monoarticular y monoarticular para multiarticular en ejercicios resistidos / Maximum repetitions and time under tension between multiarticular orders to monoarticular and monoarticular to multiarticular in resisted exercises

Objetivo: analizar las repeticiones máximas (RM) y el tiempo de tensión (TST) entre los órdenes multiarticular para monoarticular y monoarticular para multiarticular en ejercicios resistidos. Métodos: 15 hombres entrenados (23,53±2,07 años; 74,8±5,1 kg; 173,8±4,6 cm) realizaron la prueba de 10RM en los ejercicios supino horizontal (SH) y rosca tríceps en el pulley (RT). Después de 48 horas realizaron repeticiones máximas para los mismos ejercicios en diferentes órdenes multiarticular-monoarticular y monoarticular-multiarticular. En los dos protocolos propuestos, el número máximo de repeticiones y el tiempo de tensión (TST) se contabilizaron sólo en el último ejercicio realizado. Resultado: La prueba T de Student pareado apuntó reducciones significativas en el número de RM en los dos protocolos analizados cuando comparados a la prueba de 10RM (p <0,005 y p <0,001). Los resultados mostraron no haber diferencias significativas en el TST en ninguna de las condiciones evaluadas. Conclusión: el orden de los ejercicios influenció el número de repeticiones realizadas, aunque no afectó el TST.

Objective: was to analyze maximal repetitions (MR) and time under tension (TUT) between multi-joint to single-joint order and single-joint to multi-joint order in resistance exercises. Methods: Fifteen trained men (23.53 ± 2.07 years, 74.8 ± 5.1 kg, 173.8 ± 4.6cm) performed a 10RM test in the Bench Press (BP) and Arm Extension (AE). After 48h performed maximal repetitions for the same exercises in different orders, single-joint and multi-joint. In both protocols were measured the maximal repetitions (MR) and time under tension (TUT) only for the last exercise realized. Results: The paired Student's T test showed significant reductions for MR in both analyzed protocols when compared to the 10RM test (p <0.005 and p <0.001). The results showed that there were no significant differences for TUT in any of the conditions evaluated. Conclusion: The order of the exercises influenced the number of repetitions performed, although it did not affect the time under tension.

Conventional and liquid-based cytology (Liqui-PREP™) anal findings in male HIV anoreceptive patients in a referral University hospital in Rio de Janeiro, Brazil / Achados de citologia convencional e de citologia em base líquida (Liqui-PREP®) anal em pacientes masculinos HIV soropositivos anorreceptivos, em um hospital universitário de referência do Rio de Janeiro, Brasil

Introduction: The anal lesions seem to have a natural history that closely resembles cervical lesions, with signs that precede the invasion. Cytological changes of anal epithelium induced by HPV can be detected through cytology, as it is considered an effective screening method. Objective: To identify the frequency of atypical epithelial conventional cytology results by comparing anal samples through Liqui-PREPTM technology in HIV-positive men. Methods: Cross-sectional descriptive and analytical study of 33 men who have sex with men (MSM), HIV-positive and anoreceptive attended at the Gaffrèe and Guinle University Hospital (HUGG), Rio de Janeiro, from June to July, 2016. Collection of anal samples for the conventional cytology and Liqui-PREPTM cytology was carried out. For significance of findings, Fisher exact test with 95% confidence interval was used and cytological Kappa index was employed for concordance between the two cytological methods. Results: The age ranged from 23 to 60 years (mean=39.06). The CD4 cell count was between 200 to 500/mm3 on 16 (48.5%) and 13 (39.4%), and 50% was diagnosed with HIV for more than 6 years. In conventional cytology one case was considered unsatisfactory (3%). Among the cases considered satisfactory, 9 (28.1%) were diagnosed with ASC-US; 4 (12.5%) LSIL; 2 (6.3%) ASC-H, and 2 (6.3%) HSIL. Through Liqui-PREPTM method, 7 cases were considered unsatisfactory (21.2%). Among the satisfactory cases, 7 showed ASC-US (26.9%); 4 (15.4%) ASC-H; 2 (7.7%) LSIL; and 2 (7.7%) HSIL. The difference of unsatisfactory cases between both methods, although higher for Liqui-PREPTM, was not statistically significant (p=0.054). The correlation was moderate (0503; p<0.006 [0.1765­0.8298]). Conclusion: The cytologic atypia is common among MSM HIV (+), and the anal conventional cytology and liquid by Liqui-PREPTM cytology are equivalent, although they are more unsatisfactory in the latter technique.

Introdução: As lesões anais parecem ter uma história natural, que se assemelha às de lesões de colo uterino, com sinais que precedem a invasão. As alterações citológicas do epitélio anal induzidas pelo HPV podem ser detectadas por citologia, um método de rastreio considerado efetivo. Objetivo: Identificar a frequência de atipias epiteliais nos resultados da citologia convencional comparando amostras anais pela tecnologia Liqui-PREP® em homens HIV positivos. Métodos: Estudo transversal, descritivo e analítico de 33 homens que fazem sexo com homens (HSH), HIV positivos e anorreceptivos atendidos no Hospital Universitário Gaffrèe e Guinle (HUGG), Rio de Janeiro, no período de junho a julho de 2016. Os pacientes foram submetidos à coleta de amostras anais para citologia convencional e citologia Liqui-PREP®. Para significância de achados, foi usado o teste exato de Fisher com intervalo de confiança de 95%, e para concordância entre os dois métodos citológicos, foi utilizado o índice de Kappa. Resultados: A idade variou de 23 a 60 anos (média=39,06). A contagem de células CD4 foi entre 200 e 500/mm3 para 16 (48,5%) e 13 (39,4%) dos casos analisados, e 50% tinham o diagnóstico de HIV há mais de seis anos. Na citologia convencional, um caso foi considerado insatisfatório (3%). Entre os casos considerados satisfatórios, 9 (28,1%) foram diagnosticados como células escamosas atípicas de significado indeterminado possivelmente não neoplásicas (ASC-US); 4 (12,5%) como lesão intraepitelial de baixo grau (LSIL); 2 (6,3%) como células escamosas atípicas não sendo possível excluir lesão intraepitelial de alto grau (ASC-H) e 2 (6,3%) como lesão intraepitelial de alto grau (HSIL). Pelo método Liqui-PREP®, 7 casos foram considerados insatisfatórios (21,2%). Entre os casos satisfatórios, 7 como ASC-US (26,9%); 4 (15,4%) como ASC-H; 2 (7,7%) como LSIL e 2 (7,7%) como HSIL. A diferença de insatisfatório entre os métodos, embora maior para Liqui-PREP®, não foi estatisticamente significativa (p=0,054). A concordância foi moderada (0,503; p<0,006 [0,1765­0,8298]). Conclusão: É frequente a atipia citológica entre HSH HIV (+), e as citologias anal convencional e em meio líquido pela técnica Liqui-PREPTM se equivalem, embora sejam mais insatisfatórias na técnica citológica Liqui-PREP®.

Pitiriasis rosada en el embarazo: reporte de caso / Pityriasis rosea in pregnancy: case report

RESUMEN A pesar de que la Pitiriasis Rosada se considera una condición cutánea benigna, en el marco del embarazo, hay estudios que relacionan la aparición de esta patología con complicaciones asociadas en el feto. Metodología: Se realiza un reporte de caso, prospectivo, a una mujer de 36 años chilena que presentó esta patología durante la semana 12 de gestación. El objetivo fue describir, la evolución y control y contrastar su evolución con la evidencia científica actual sobre esta temática. Resultados: Paciente presenta placas eritematodescamativas concordantes con diagnóstico de pitiriasis rosada (superficie afectada menos al 50% de su cuerpo), sin presentar enantema, ni síntomas sistémicos. Tuvo un recién nacido sano a las 38 semanas de gestación, sin presentar ningún efecto adverso de los que relaciona la literatura analizada. Conclusiones: Distintos estudios han estudiado los posibles efectos adversos en el feto en madres que han presentado Pitiriasis Rosada en el embarazo, sin embargo, en este reporte de caso no se presentaron complicaciones asociadas. Faltan estudios realizados en mayor cantidad de pacientes.

ABSTRACT Although Pityriasis Rosea is considered a benign cutaneous condition, in the context of pregnancy, there are studies that relate the appearance of this pathology with associated complications in the fetus. Methodology: A prospective case report was made to a 36-year-old Chilean woman who presented this pathology during the twelve weeks of pregnancy. The objective was to describe, the evolution and control and to contrast its evolution with the current scientific evidence on this subject.

Facial botryomycosis-like pyoderma in an HIV-infected patient: remission after initiation of darunavir and raltegravir

Abstract Botryomycosis is an uncommon, chronic, suppurative, bacterial infection that primarily affects the skin and subcutaneous tissues. It has long been associated with defects of cellular immunity. We report a 28-year-old woman who presented with a chronic, ulcerated lesion with draining sinuses in the right malar region. Predisposing factors were HIV infection with poor immunological control, alcoholism, and a previous trauma to the right cheek. Several courses of antimicrobial therapy provided only partial and temporary remission. Complete clinical remission was only achieved 5 years later when a novel antiretroviral regimen composed of darunavir and raltegravir was initiated.

Ethnobotany and popular culture in the use of plants in settlements on the southern edge of southern Pantanal Mato Grosso / Etnobôtanica e a cultura popular no uso de plantas em assentamentos na borda sul do pantanal sul-mato-grossense

Popular culture and its relationship with plants has been the subject of scientific studies and brought significant contributions to science. In this assessment, developed in two settlements in Corumbá and Ladário, Mato Grosso do Sul, was evaluated the use of plants for medicinal purposes. A structured questionnaire was administered to 10 raizeiros, residents of the area, asking which plants were used by them, their methods of preparation and therapeutic indications. Fifty-five plants from 28 families were catalogued among plants native to the region and of exotic and/or external origin, only 40% were native. The predominant form of use is tea (41 citations), followed by infusion (16 citations). The most used parts are the leaves, with 43 citations, followed by flowers (6 citations). There is a predominance of the type of problem for which the plant is used, with 12 citations for problems in the respiratory system, followed by eight for kidney and liver problems and seven for the stomach. What has been found is a wide diversity of species used for the most different problems, indicating the importance of the use of medicinal plants for the communities studied.

A cultura popular e sua relação com as plantas tem sido objeto de estudos científicos e trazido contribuições significativas para a ciência. Nesta pesquisa desenvolvida em dois assentamentos nos municípios de Corumbá e Ladário, Mato Grosso do Sul, foi avaliada a utilização de plantas para fins medicinais. Um questionário estruturado foi aplicado a 10 raizeiros, residentes nos locais, buscando identificar quais plantas eram utilizadas, seus métodos de preparação e indicações terapêuticas. Foram catalogadas 55 plantas de 28 famílias, entre nativas da região e exóticas e/ou de origem externa, sendo que apenas 40% eram nativas. A forma de uso predominante é o chá (41 citações), seguida por infusão (16 citações). As partes mais utilizadas são as folhas, com 43 citações, seguida pelas flores (16 citações). Há uma predominância quanto ao tipo de problema para qual a planta é usada, com 12 citações para problemas no sistema respiratório, seguido por oito para problemas renais e hepáticos e sete relacionadas ao estômago. Verificou-se uma ampla diversidade de espécies utilizadas, para os mais diferentes problemas, indicando a importância da utilização das plantas medicinais para as comunidades estudadas.
