Assessment of the renal angina index for the prediction of acute kidney injury in patients admitted to a European pediatric intensive care unit.

BACKGROUND: Acute kidney injury (AKI) is associated with worse outcomes and increased morbidity and mortality in pediatric intensive care unit (PICU) patients. The renal angina index (RAI) has been proposed as an early prediction tool for AKI development. OBJECTIVES: The objective was to evaluate outcomes of RAI-positive patients and to compare RAI performance with traditional AKI markers across different patient groups (medical/post-surgical). This was an observational retrospective study. All children admitted to a tertiary hospital PICU over a 3-year period were included. Electronic medical records were reviewed. Day 1 RAI was calculated, as was the presence and staging of day 3 AKI. RESULTS: A total of 593 patients were included; 56% were male, the mean age was 55 months, and 17% had a positive RAI. This was associated with day 3 AKI development and worse outcomes, such as greater need for kidney replacement therapy, longer duration of mechanical ventilation, vasoactive support and PICU stay, and higher mortality. For all-stage kidney injury, RAI presented a sensitivity of 87.5% and a specificity of 88.1%. Prediction of day 3 all-stage AKI by RAI had an AUC=0.878; its performance increased for severe AKI (AUC = 0.93). RAI was superior to serum creatinine increase and KDIGO AKI staging on day 1 in predicting severe AKI development. The performance remained high irrespective of the type of admission. CONCLUSIONS: The RAI is a simple and inexpensive tool that can be used with medical and post-surgical PICU patients to predict AKI development and anticipate complications, allowing for the adoption of preventive measures.

Microbiome in Nasal Mucosa of Children and Adolescents with Allergic Rhinitis: A Systematic Review.

The human upper respiratory tract comprises the nasal cavity, pharynx and larynx regions and offers distinct microbial communities. However, an imbalance and alterations in the nasal mucosa microbiome enhance the risk of chronic respiratory conditions in patients with allergic respiratory diseases. This is particularly important in children and adolescents once allergic rhinitis (AR) is an inflammatory disorder of the nasal mucosa, often associated with an increase in pulmonary allergic inflammation. Therefore, this systematic review aimed to collect scientific data published concerning the microbial community alterations in nasal mucosa of children and adolescents suffering from AR or in association with adenotonsillar hypertrophy (AH) and allergic rhinoconjunctivitis (ARC). The current study was performed using the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Publications related to microbiome alterations in the nasal mucosa in pediatric age, studies including next-generation sequencing platforms, and studies exclusively written in the English language were some of the inclusion criteria. In total, five articles were included. Despite the scarcity of the published data in this research field and the lack of prospective studies, the genera Acinetobacter, Corynebacterium, Dolosigranulum, Haemophilus, Moraxella, Staphylococcus and Streptococcus dominate the nares and nasopharyngeal microbiome of the pediatric population regardless of their age. However, an imbalance in the resident bacterial community in the nasal mucosa was observed. The genera Acinetobacter, and Pseudomonas were more abundant in the nasal cavity of AR and AH children, while Streptococcus and Moraxella were predominant in the hypopharyngeal region of AR infants. An abundance of Staphylococcus spp. was also reported in the anterior nares and hypopharyngeal region of children and adolescents suffering from AR passive smoke exposure and ARC. These records suggest that different nasal structures, ageing, smoke exposure and the presence of other chronic disorders shape the nasal mucosa microbiome. Therefore, the establishment of adequate criteria for sampling would be established for a deeper understanding and a trustworthy comparison of the microbiome alterations in pediatric age.

Anakinra and hepatotoxicity in pediatric rheumatology: a case series.

BACKGROUND: Anakinra is a recombinant interleukin-1 (IL-1) receptor antagonist used in systemic juvenile idiopathic arthritis (sJIA), refractory Kawasaki disease (KD) and cryopyrin-associated autoinflammatory syndrome (CAPS). Anakinra associated hepatotoxicity, while rare, has been described in several cases in daily practice. ​In this case series the authors describe three pediatric patients with this side effect in the setting of severe macrophage activation syndrome (MAS) in KD and sJIA. CASE PRESENTATION: The first patient was a 12-year-old boy who presented with fever, maculo-papular exanthema and polyarthralgia. Tonsillitis, distal limb induration and tender cervical lymph nodes were observed. Erythrocyte-sedimentation rate (ESR), C-reactive protein (CRP), ferritin (11,975 ng/mL), D-dimers (5,98 mg/L FEU) and soluble CD25 (3645 pg/mL) levels were elevated. Exclusion of sepsis / toxic shock syndrome warranted introduction of IV methylprednisolone and immunoglobulin (IG IV), with partial response. A MAS secondary to KD was assumed, and anakinra 2 mg/kg/day was introduced. Twenty days later he developed new-onset nausea and severe cyto-cholestasis, normalizing after 2 months of drug discontinuation. Posterior onset of polyarthritis and evanescent lead to a final diagnosis of sJIA. The second patient was a 2-year-old boy with a 10-day history of fevers, generalized rash, hepatosplenomegaly and strawberry tongue. Leucocytosis with neutrophilia and elevated CRP were observed. Initial treatment with IVIG in the setting of incomplete KD was ineffective. Mild anaemia, leukopenia and very high serum ferritin (maximum 26,128 ng/mL) ensued. Presumptive sJIA associated MAS was treated with IV methylprednisolone and anakinra 2 mg/kg/day, with prompt response. Four weeks later transaminitis was detected, and temporary anakinra suspension led to normalisation of laboratorial values. The third case related to a 4-year-old boy presenting with fever, maculopapular rash and cervical lymphadenopathy. CRP and ESR were elevated, and KD was diagnosed. IVIG and methylprednisolone were initiated with clinical worsening, warranting for anakinra introduction at 2 mg/kg/day. After three weeks, liver enzymes progressively elevated, resolving on 2 weeks of anakinra discontinuation. CONCLUSIONS: To the best of our knowledge, this is the first case series describing anakinra associated hepatotoxicity in pediatric patients with rheumatic diseases other than sJIA, bringing additional insight to therapeutic monitoring in patients undergoing this treatment.

Does preappointment gabapentin affect neurological examination findings? A prospective, randomized and blinded study in healthy cats.

OBJECTIVES: The aim of this study was to evaluate the influence of a preappointment oral dose of gabapentin on the neurological examination of cats. METHODS: A prospective, randomized and blinded clinical trial was conducted in 35 client-owned healthy cats. Cats were scheduled for two appointments and randomly assigned to receive either a placebo or a 100 mg gabapentin capsule prior to the second veterinary visit. A neurological examination was performed during each visit, and the results were compared between groups. Normal/abnormal response rates for each test were based on the number of cats that allowed the test to be performed. RESULTS: Gabapentin was administered to 17 cats. Gait and postural reactions were significantly affected in the gabapentin group. Comparing the gabapentin with the placebo groups, proprioceptive ataxia was identified in 4/17 (23.5%) vs 0/18 cats (P = 0.0288); paw placement deficits were seen in 10/11 (90.9%) vs 1/4 (25%) cats; table tactile placement deficits were identified in 13/17 (76.5%) vs 0/18 cats (P <0.0001); hopping deficits were seen in 5/17 (29.4%) vs 0/16 cats (P = 0.0185); and abnormalities on wheelbarrowing and extensor postural thrust were reported in 5/17 (29.4%) vs 0/18 cats (P = 0.0129). These results had no correlation with age or dose/kg received. No significant difference was noted in the assessment of level and content of consciousness, posture, cranial nerves and spinal nerves. No significant differences were noted in test compliance or examination duration. CONCLUSIONS AND RELEVANCE: Gabapentin significantly altered gait analyses and postural reactions in this group of healthy cats. The administration of gabapentin could lead to false-positive results and, possibly, an incorrect identification of neurological lesions. In contrast, gabapentin did not impair the assessment of cranial nerves and spinal reflexes, which can be assessed in patients receiving the drug.

Evaluation of the effects of gabapentin on the physiologic and echocardiographic variables of healthy cats: a prospective, randomized and blinded study.

OBJECTIVES: The aim of this study was to evaluate, using echocardiography, the effects of oral administration of a single dose of gabapentin on the physiologic variables (heart rate [HR], respiratory rate [RR] and systolic blood pressure [SBP]) and systolic and diastolic cardiac function of healthy cats. METHODS: This was a prospective, randomized and blinded study with 40 healthy cats aged between 6 months and 2 years. The cats' health status was assessed on the first appointment (T1) when they underwent a physical examination, complete blood count, biochemical profile, assessment of physiologic variables and echocardiogram. The echocardiogram was used to measure the left ventricle's (LV) internal diameter during systole and diastole, isovolumic relaxation time, transmitral flow, E-wave deceleration time and HR. The cats were randomly divided into two groups: (1) a treatment group with 20 cats that received a single oral dose of gabapentin (100 mg/cat); and (2) a control group with 20 cats that received a single oral dose of placebo. All variables of the physiologic and echocardiographic variables were re-evaluated 1-3 weeks after T1 (T2), 90 mins after medication or placebo administration. RESULTS: There was no difference in the physiologic variables evaluated in both groups. The proportion of cats in the treatment group that had their ventricular filling waves fused on T1 but did not have them fused on T2 was significantly higher (45%) compared with cats in the control group (15%; P = 0.0384). CONCLUSIONS AND RELEVANCE: There was no difference between the groups in regard to SBP, HR, RR and echocardiographic variables. Gabapentin improved evaluation of diastolic function on echocardiogram because it reduced the fusion of ventricular filling waves during the evaluation of the diastolic function of the LV. Gabapentin did not cause adverse effects on the cardiovascular hemodynamics of young healthy cats.

Sarcoidosis presenting as gingival erosion in a patient under long-term clinical control.

BACKGROUND: Sarcoidosis is an inflammatory granulomatous systemic disease that rarely affects the oral cavity. Gingival involvement has been reported in only a very limited number of cases, occasionally as the first manifestation of the disease. This article reports a case of sarcoidosis affecting the gingiva and alveolar mucosa in a patient previously treated for the systemic disease and considered under long-term clinical control. METHODS: A 57-year-old white female presented with a chief complaint of gingival pain in the maxillary right area lasting 3 years. Clinical examination revealed an erythematous, ill-defined erosive macule on the buccal aspect of the maxillary right gingiva extending from the canine to the third molar. The medical history included a diagnosis of sarcoidosis 16 years prior to presentation, which was considered to be under clinical control for the last 11 years. An incisional biopsy was obtained. RESULTS: Histopathology indicated the presence of an intense chronic inflammatory infiltrate and focal areas with non-caseating granulomas. Periodic acid-Schiff and Grocott's stains were negative for microorganisms, and the diagnosis was compatible with sarcoidosis. Systemic evaluation showed no involvement of other areas and organs, and the patient was managed with topical steroid therapy using silicone trays in conjunction with conventional periodontal therapy and oral hygiene instructions. Complete response was achieved after 6 months, and the patient remains in clinical follow-up. CONCLUSION: Although sarcoidosis is a systemic disease that rarely affects the gingiva, the possibility of gingival involvement as the sole manifestation of the disease should be considered in the differential diagnosis of gingival lesions.

Giant simple biliary cyst infection treated with minimally invasive percutaneous drainage.

We describe a minimally invasive alternative approach in a patient with infected hepatic cyst to stabilize the patient before definitive surgery. A 58-year-old man presented with fever and hypotension after 2 weeks of asthenia, chills, weight loss, slight abdominal pain, and a previous asymptomatic simple hepatic cyst. On ultrasound, a giant heterogeneous hepatic cyst with thick wall was noted. A positron emission tomography-computed tomography scan was indicated and demonstrated high uptake (standardized uptake value = 7.6) in the wall of the cyst, suggestive of infection. He underwent percutaneous drainage guided by the tomography. A 12 Fr drain was positioned inside the collection and 5 L of purulent material was aspirated from the cyst, and at day 12th, surgical resection was performed. Histopatological analysis confirmed a simple biliary cyst. The patient remains asymptomatic on 1-year follow-up. Percutaneous drainage before surgical treatment allowed the definitive approach to be performed with the patient in better clinical conditions.

Introduction:Endometriosis is a gynecological pathology that is quite prevalent among women of multiple age groups, representing a constant challenge to fertility, sexuality, and other aspects of quality of life.Objective:To evaluate the epidemiological profile, forms of treatment and biopsychosocial aspects associated with the sexual health of women with endometriosis.Methodology:This is an integrative review of the literature whose guiding question was "How does endometriosis influence the biopsychosocial aspects inherent to female sexual behavior?". The search strategy "Endometriosis AND Dyspareunia AND Quality of Life" was applied in the Biblioteca Virtual em Saúde (BVS) and in the PubMed database, with the "last 10 years" filter applied on both platforms. Inclusion criteria: studies that addressed cisgender women, of childbearing age, with active sexual life, previous diagnosis of pelvic or deep endometriosis and sexual disorders or complaints. Exclusion criteria: articles that included women using psychotropic drugs. Results:Initially, 227 articles were obtained. After primary analysis, 189 studies were excluded, only 38 going on to the next stage. Of these, only 15 met the criteria and were considered valid to be part of the present study. In the sexual sphere, endometriosis can lead to a reduction in the frequency of intercourse, bleeding during or after coitus, lack of interest in foreplay, discomfort in certain positions, relationship endings, marital conflicts, and, above all, dyspareunia.Conclusions:Given the damage to various areas of life and female well-being caused by endometriosis, it is essential to improve the quality of health services for early diagnosis and effective interventions, as well as support, reception, and continuous multidisciplinary monitoring. Furthermore, adaptation, understanding and concern from partners are fundamental for women to be able to better manage such challenges (AU).

Image-guided percutaneous renal cryoablation: Five years experience, results and follow-up.

OBJECTIVES: To describe the experience of our institution in image-guided renal nodules percutaneous cryoablation, evaluating demographic and technical aspects as well as efficacy, safety and follow up. MATERIALS AND METHODS: Retrospective study approved by our institutional review board. Seventy-one renal tumors evaluated in 60 patients treated with image guided percutaneous renal cryoablation from January 2009 to December 2015. No patient was excluded from study, even those who were lost on follow up. All the procedures were guided both by ultrasound and tomography. An argon and helium based cryoablation machine was used for all treatments. Hydrodissection was performed when the bowel or ureters were within 1 cm (iodinated contrast media in dextrose solution). Complications were assessed by the terminology criteria of the National Institutes of Health (NIH). Patients were monitored and evaluated by ultrasound, tomography, MRI and/or PET-CT. RESULTS: In most procedures (91.9%) only one nodule was treated. Nodules had a median size of 1.6 cm. Most nodules (61,9%) were exophytic. Hydrodissection and retrograde warm pyeloperfusion were performed in most procedures. Among all variables evaluated in univariate analysis, nearness of nodule to collecting system and anterior/posterior location were significantly associated with PRCA complications. No other factor evaluated was significantly associated with complications. CONCLUSION: PRCA is solid alternative to traditional surgical therapies for treatment of small renal tumors in wide subset of patients. Medium term evidence shows excellent long-term oncological results, similar to nephrectomy, with minimal risk of major complications.

Dose-dependent effect of triiodothyronine on the chondrogenic differentiation of mesenchymal stem cells from the bone marrow of female rats.

OBJECTIVES: Verify the in-vitro effect of triiodothyronine (T3) on the chondrogenic differentiation of female rat bone marrow mesenchymal stem cells (BMMSCs) over several time periods and at several doses. METHODS: CD54 + /CD73 + /CD90 +  BMMSCs from Wistar female rats were cultured in chondrogenic medium with or without T3 (0.01; 1; 100; 1000 nm). At seven, 14 and 21 days, the cell morphology, chondrogenic matrix formation and expression of Sox9 and collagen II were evaluated. KEY FINDINGS: The dose of 100 nm did not alter the parameters evaluated in any of the periods studied. However, the 0.01 nm T3 dose improved the chondrogenic potential by increasing the chondrogenic matrix formation and expression of Sox9 and collagen II in at least one of the evaluated periods; the 1 nm T3 dose also improved the chondrogenic potential by increasing the chondrogenic matrix formation and the expression of collagen II in at least one of the evaluated periods. The 1000 nm T3 dose improved the chondrogenic potential by increasing the chondrogenic matrix formation and Sox9 expression in at least one of the evaluated periods. CONCLUSIONS: T3 has a dose-dependent effect on the differentiation of BMMSCs from female rats.

Annual deterioration of renal function in hypertensive patients with and without diabetes.

BACKGROUND: Chronic kidney disease (CKD) complicates hypertension and diabetes. Knowledge of the deterioration rate of CKD may anticipate adjustment of therapies with renal elimination. This study evaluates the rate of annual deterioration of renal function in hypertensive patients either with type 2 diabetes (DM2) or without it (non-DM) followed for 5 years and relates it with blood pressure (BP) and glycemic control. MATERIALS AND METHODS: Out of a total of 1924 patients, 1023 patients (594 non-DM and 429 DM2, 53% female, aged 62.1±10.2 years) were evaluated over 5 years for the annual evolution of renal function (estimated glomerular filtration rate [eGFR], Modification of Diet in Renal Disease) ambulatory 24-hour blood pressure and metabolic parameters, corresponding to the analysis of 2378 patient-years. RESULTS: DM2 and non-DM did not differ for age, mean 24-hour BP levels, nighttime BP, albuminuria, and body mass index. DM2 versus non-DM showed a higher (p<0.02) prevalence of stage 3 CKD (24.0% vs 18.0%, eGFR 30-59), stage 4 (5.4% vs 2.7%, eGFR 15-29), and stage 5 (0.8% vs 0.5%, eGFR <15). Average annual decline of eGFR was 3.3±8.2 in DM2 versus 2.4±7.7 in non-DM (p=0.12, nonsignificant). Annual changes of eGFR and of albuminuria correlated (r=0.578, p<0.001). In multivariate analysis, age, nighttime BP, double inhibition of renin angiotensin system, albuminuria, and HbA1c >8.0% in DM2 predicted the decline in eGFR. On average, 16.2% of DM2 and 13.1% of non-DM moved each year toward a more severe stage of CKD. For initial eGFR <90 mL/min/1.73 m2, 26.4% of DM2 and 18.1% of non-DM patients showed a reduction per year >10% from the previous eGFR value (p=0.042). CONCLUSION: Progressive deterioration of renal function each year is frequent in hypertensive diabetic and non-diabetic patients. Beyond aging, this is particularly dependent on BP control particularly at nighttime, on drug therapy, and on highly abnormal glucose control.

Percutaneous Cholecystostomy and Hydrodissection in Radiofrequency Ablation of Liver Subcapsular Leiomyosarcoma Metastasis Adjacent to the Gallbladder: Protective Effect.

Uterine leiomyosarcoma is an uncommon pathology, predominantly found in aged population. Patients with metastatic disease have poor survival and therapy mainly consists of palliative systemic chemotherapy. However, more aggressive strategies such as radiofrequency ablation (RFA) may benefit patients with limited secondary disease. RFA is considered a simple and safe modality for treatment of hepatic lesions. The benefits related to RFA include low morbidity, short hospital stay and the possibility to repeat the procedure when necessary due to recurrences. However, minor and major complications related to mechanical and thermal damage may occur, especially in cases of tumors adjacent to extrahepatic organs and those at subcapsular position. This case report shows a successful RFA of two hepatic subcapsular leiomyosarcoma metastases neighbouring the gallbladder, without a safe cleavage plane from it. Combined hydrodissection, percutaneous cholecystostomy and continuous irrigation were performed as effective techniques to prevent thermal injury. Clinical and radiological follow up demonstrates no local complication.

Percutaneous Treatment of Intrahepatic Biliary Leak: A Modified Occlusion Balloon Technique.

PURPOSE: To report a novel modified occlusion balloon technique to treat biliary leaks. METHODS: A 22-year-old female patient underwent liver transplantation with biliary-enteric anastomosis. She developed thrombosis of the common hepatic artery and extensive ischemia in the left hepatic lobe. Resection of segments II and III was performed and a biliary-cutaneous leak originating at the resection plane was identified in the early postoperative period. Initial treatment with percutaneous transhepatic drainage was unsuccessful. Therefore, an angioplasty balloon was coaxially inserted within the biliary drain and positioned close to the leak. RESULTS: The fistula output abruptly decreased after the procedure and stopped on the 7th day. At the 3-week follow-up, cholangiography revealed complete resolution of the leakage. CONCLUSION: This novel modified occlusion balloon technique was effective and safe. However, greater experience and more cases are necessary to validate the technique.

Direito ao aborto, gênero e a pesquisa jurídica em direitos fundamentais / Derecho al aborto, género y la investigación jurídica en derechos fundamentales / Abortion rights, gender and legal research on fundamental rights

Resumo A partir de um retrato da situação atual do abortamento inseguro e de uma breve reconstrução das lutas feministas pela descriminalização do aborto no Brasil, o trabalho discute o papel do constitucionalismo democrático no reconhecimento de novos sujeitos de direitos sexuais e reprodutivos. Recorremos ao fundamento político-filosófico dos direitos sexuais e reprodutivos para apontar que sua regulamentação jurídica só tem validade se os "sujeitos de direitos" construídos e pressupostos por sua regulamentação não se prestarem à violação dos postulados fundamentais do constitucionalismo democrático. Tal violação ocorre quando as relações de inclusão e exclusão estabelecidas por seus contornos hipotéticos se prestam a negar reconhecimento institucional à plena dignidade de experiências identitárias dissidentes. Propomos a utilização da teoria de Rosenfeld em pesquisas sobre direito ao aborto sob a perspectiva do Direito Constitucional. Esta teoria permite ver como os discursos sobre direitos criam e enunciam seus sujeitos com marcas de gênero, e podem servir tanto à ampliação das liberdades como de formas de subordinação.

Resumen A partir de un retrato de la situación actual del aborto clandestino y de una breve reconstrucción de las luchas feministas por la despenalización del aborto en Brasil, este trabajo discute el rol del constitucionalismo democrático en el reconocimiento de nuevos sujetos de derechos sexuales y reproductivos. Recurrimos al fundamento político-filosófico de los derechos sexuales y reproductivos para sugerir que su reglamentación jurídica sólo puede tener validez si los "sujetos de derechos" construidos y presupuestos por dicha reglamentación no son utilizados como instrumento para la violación de los postulados fundamentales del constitucionalismo democrático. Esto ocurre cuando las relaciones de inclusión y exclusión establecidas por sus contornos hipotéticos sirven para negar reconocimiento institucional a la plena dignidad de experiencias de identidad disidentes. Sugerimos la utilización de la teoría de Rosenfeld en investigaciones sobre derecho al aborto bajo la perspectiva del derecho constitucional. Esta teoría permite mostrar cómo los discursos sobre derechos crean y enuncian sus sujetos con marcas de género y pueden servir tanto a la ampliación de las libertades como o a formas de subordinación.

Abstract After a brief portrayal of the situation of unsafe abortion in Brazil and the feminist struggles for the decriminalization of abortion, this paper discusses the role of democratic constitutionalism in the acknowledgment of new subjects of sexual and reproductive rights. I resort to the political and philosophical basis of sexual and reproductive rights to suggest that the legal regulation can only be considered valid if the "legal subjects" constructed and presupposed by those regulations do not violate the basic grounds of democratic constitutionalism. This happens whenever the relations of inclusion and exclusion posed by their hypothetical contours deny institutional acknowledgment for the experience dissident identities. I suggest the employment of Rosenfeld's theory for researching abortion rights on a constitutional perspective. This theory provides a tool to show how discourses about rights create and enunciate gendered subjects, and they may work to either expand freedom, or enhance forms of subordination.
