Introducing an ANP-led temporal artery biopsy service for patients with suspected giant cell arteritis.

Giant cell arteritis (GCA) is an uncommon autoimmune inflammatory vasculopathy that can lead to the destruction and occlusion of various arteries that consequently can cause serious complications such as stroke or sight loss. It is seen as a medical emergency. The most commonly affected vessel in GCA is the temporal artery in the side of the head, hence the condition is sometimes also referred to as 'temporal arteritis'. This article discusses the introduction of an advanced nurse practitioner-led temporal artery biopsy service.

Proceso de atención de enfermería a un paciente pediátrico en el transcurso de una biopsia renal / Nursing care process to a paediatric patient during a renal biopsy

DESCRIPCIÓN DEL CASO: Paciente de 13 años que ingresa en hospital de tercer nivel, procedente de consultas externas de Nefrología pediátrica del mismo hospital para biopsia renal, al sufrir, en valoraciones anteriores, episodios de hematurias microscópicas persistentes, macroscópicas intermitentes y proteinuria en rango nefrótico. DESCRIPCIÓN DEL PLAN DE CUIDADOS: La unidad de enfermería pediátrica del hospital estableció un plan de cuidados inicial al ingreso y postquirúrgico ajustados a la patrones funcionales de Marjory Gordon, considerando los patrones relacionados con temor en el niño, ansiedad y cavilación de la familia, resultando de estos hechos la activación del protocolo de acogida, aumento del nivel de estrés debido a modificación ingesta alimentos, aumentar el afrontamiento en la fase postquirúrgica así como dolor, riesgo de infección, disconfort, sobrepeso por alimentación insana y hematurias postbiopsia. EVALUACIÓN DEL PLAN: Durante el ingreso hospitalario de 4 días previo a la biopsia se le realizaron pruebas bioquímicas de sangre y orina de 24 horas y estudio de anemia. Los progenitores se mostraban muy interesados por la evolución de las pruebas y como contener la ansiedad y tener calmado al hijo debido al conocimiento de que le harían una punción. Mientras se encontraba hospitalizado no cumplía los requisitos nutricionales. Al día siguiente de la biopsia fue dado de alta con unas pautas para comenzar con una alimentación más sana. CONCLUSIONES: La taxonomía NANDA/NOC/NIC permite trabajar en la enfermería basada en los hallazgos, dando respuesta a las necesidades reales de los pacientes para contribuir a mejorar la práctica clínica

CLINICAL CASE: A 13-year-old patient admitted to a third-level hospital from paediatric nephrology outpatient clinics for a renal biopsy after suffering, in previous evaluations, episodes of intermittent macroscopic and persistent microscopic haematuria and nephrotic-range proteinuria. DESCRIPTION OF THE CARE PLAN: The hospital paediatric nursing unit established an initial care plan on admission and after surgery adjusted to Gordon's functional patterns, considering the patterns related to fear in the child, anxiety and family melancholy, resulting in the activation of the reception protocol, increased stress level due to food intake modification, increased coping in the post-surgical phase as well as pain, risk of infection, discomfort, overweight due to unhealthy eating and post-biopsy haematuria. EVALUATION OF THE CARE PLAN: During the 4-day hospital stay prior to the biopsy, 24-hour blood and urine biochemical tests and anemia study were performed. The parents were very interested in the evolution of the tests and how to contain anxiety and keep the child calm due to the knowledge that they would do a blood puncture. While he was hospitalized, he did not meet the nutritional requirements. The day after the biopsy, he was discharged with guidelines to start a healthier diet. CONCLUSIONS: The NANDA/NOC/NIC taxonomy allows working in nursing based on findings, responding to the real needs of patients to help improve clinical practice

Urology nurses lead the way in adopting an innovative prostate biopsy technique.

Jonah Rusere, Advanced Nurse Practitioner for South East London Accountable Cancer Network, outlines an opportunity for urology nurses to make a difference to prostate cancer pathways.

The Effect of Barcode Technology Use on Pathology Specimen Labeling Errors.

Pathology specimen labeling errors occur for a variety of reasons. We investigated the use of barcode technology as a method to improve the accuracy of pathology specimen labeling and patient safety. We also assessed nurses' perceptions of system quality, information quality, service quality, user satisfaction, and net benefits. Sixty-eight perioperative nurses who work in a teaching hospital in Taiwan completed the survey. Nurses scored net benefits as highly contributing to their satisfaction, whereas system quality contributed most to dissatisfaction. Further, we analyzed pathology specimen records before and after implementing the barcode system and found that specimen management errors significantly decreased. The use of a reliable barcode system could improve specimen labeling accuracy and enhance nurses' satisfaction with this technology.

O itinerário terapêutico do paciente em tratamento oncológico: implicações para a prática de enfermagem / El itinerario terapéutico del paciente en tratamiento oncológico: implicaciones para la práctica de enfermería / The therapeutic itinerary of patient in oncological treatment: implications for nursing practice

RESUMO A trajetória do cliente oncológico ainda é permeada por percalços que interferem em seu prognóstico e qualidade de vida. Assim, este estudo visa a mapear o itinerário do paciente oncológico desde o diagnóstico até o tratamento e analisar suas implicações nas ações de enfermagem para o controle do câncer. Estudo qualitativo, realizado através da técnica de história oral de dez clientes oncológicos atendidos em um hospital federal no município do Rio de Janeiro, Brasil. Os dados foram tratados de acordo com a técnica de análise temática, além da confecção de representações do itinerário terapêutico de cada entrevistado. Foram identificados três eixos temáticos: trajetória antes do diagnóstico, trajetória do diagnóstico ao início do tratamento, e trajetória no tratamento. Percebe-se que o acesso aos serviços apresenta-se como um problema que culmina no agravamento da doença, no aparecimento de metástases e a morte do paciente, além de criar condições para a falta de adesão ao tratamento.

Estudio cualitativo, realizado a través de la técnica de historia oral de diez clientes oncológicos atendidos en un hospital federal en el municipio de Rio de Janeiro, Brasil. Los datos fueron tratados de acuerdo con la técnica de análisis temático, además de la confección de representaciones del itinerario terapéutico de cada entrevistado. Fueron identificados tres ejes temáticos: trayectoria antes del diagnóstico; trayectoria del diagnóstico al inicio del tratamiento; y trayectoria en el tratamiento. Se nota que el acceso a los servicios se presenta como un problema que culmina en el agravamiento de la enfermedad, el en surgimiento de metástasis y la muerte del paciente, además de crear condiciones para la falta de adhesión al tratamiento.

ABSTRACT The course of oncology patients is still crossed by setbacks that interfere with their prognosis and quality of life. This study aims to map the itinerary of cancer patients from diagnosis to treatment and to analyze its implications in nursing healthcare practices for the control of cancer. This is a qualitative study, conducted using oral history technique with ten cancer patients treated in a federal hospital in the city of Rio de Janeiro, Brazil. The data were analyzed according to thematic analysis technique and with the making of representations of the therapeutic itinerary of each interviewee. Three main themes were identified: course before diagnosis, course from diagnosis to the beginning of treatment, and course during treatment. We observed that the access to medical services is presented as a problem that culminates in the worsening of the disease, appearing of metastases and death of the patient, in addition to creating conditions that hinder the adherence to treatment.

¿Es posible aumentar la especificidad para la realización de biopsia prostática en pacientes con PSA entre 4-10 ng/ml con cociente PSA libre/PSA total < 20%? / Is it possible to increase the specificity for the performance of prostatic biopsy in patients with PSA between 4 and 10 ng/ml and free/total PSA ratio 20%?

OBJETIVO: En la actualidad sigue siendo un problema la toma de decisión para realizar biopsia de próstata en pacientes con PSA entre 4-10 ng/ml, a pesar del uso del cociente PSA libre/ PSA total. El objetivo de este estudio es investigar la manera de aumentar la especificidad en la toma de decisión de la realización de biopsia de próstata en este tipo de pacientes. MÉTODOS: Desde enero a diciembre de 2014, se incluyen en este estudio hombres con PSA entre 4-10ng/ml y cociente PSA libre/ PSA total <20%, candidatos a biopsia de próstata. Se excluyen del estudio pacientes que estén tomando inhibidores de la 5 alfa-reductasa y pacientes con biopsias de próstata previamente realizadas. Se analiza edad, PSA total, testosterona total, libre y biodisponible, FSH, LH, SHBG, 17-hidroxiprogesterona, Androstendiona, volumen prostático (medido por ecografía transrectal), cocientes testosterona total/PSA, testosterona libre/PSA, testosterona biodisponible/PSA y Densidad de PSA, testosterona total/volumen próstata, testosterona libre/volumen próstata y testosterona biodisponible/volumen próstata. Análisis estadístico con SPSS 20,0 y significación estadística p≤0,05. RESULTADOS: Un total de 109 pacientes se incluyeron, divididos en 2 grupos según resultado de la biopsia. Grupo 1: 49 pacientes con biopsia de próstata positiva; Grupo 2: 60 pacientes con biopsia de próstata negativa. Se observan diferencias estadísticamente significativas en relación al volumen prostático (Grupo 1: 37,6 cc; Grupo 2: 52,8 cc; p = 0,04), densidad PSA (Grupo 1: 0,24; Grupo 2: 0,17; p = 0,002), testosterona total/volumen próstata (Grupo 1: 0,15; Grupo 2: 0,10; p = 0,02), testosterona libre/volumen próstata (Grupo 1: 0,002; Grupo 2: 0,001; p = 0,01) y testosterona biodisponible/volumen próstata (Grupo 1: 0,06; Grupo 2: 0,04; p = 0,007). Se realiza curva ROC para determinación de punto de corte con especificidad 90%, observando que un volumen de próstata menor a 60,7cc, una densidad de PSA mayor a 0,27 y un valor testosterona biodisponible/volumen próstata mayor a 0,07. CONCLUSIÓN: La decisión de biopsia de próstata en pacientes con PSA entre 4-10 ng/ml con cociente PSA libre/PSA total < 20% sigue siendo controvertida, no obstante podemos optimizar la decisión utilizando otros parámetros como el volumen de próstata, la densidad PSA y el cociente testosterona biodisponible/volumen próstata

OBJECTIVE: To investigate the manner to increase specificity in the decision-making process for the performance of prostate biopsy. METHODS: We include in this study men with PSA between 4 and 10 ng/ml and free/total PSA < 20%, candidates for prostate biopsy. Patients receiving 5 alpha reductase inhibitors or with previous biopsies were excluded. Analyzed variables: total PSA, total testosterone, free and bioavailable testosterone, FSH, LH, SHBG, 17 hydroxyprogesterone, Androstenedione, prostatic volume measured by transrectal ultrasound, total testosterone/PSA, testosterone/free PSA, bio available testosterone/PSA and PSA density, total testosterone/prostate volume, free testosterone/prostate volume and bioavailable testosterone/prostate volume. RESULTS: A total 109 patients have been included, divided into 2 groups according to the results of the biopsy. Significant differences were observed in prostatic volume (Group 1: 36.6cc and Group 2: 52.8 cc; p = 0.04), PSA density (Group 1: 0.24 Group 2: 0.17; p = 0.002), total testosterone/prostate volume (Group 1: 0.15 and Group 2: 0.10; p = 0.02) free testosterone/ prostate volume (Group 1: 0.002 Group 2: 0.001; p = 0.01) and bioavailable testosterone/prostate volume (Group 1: 0.06 Group 2: 0.04; p = 0.007). CONCLUSION: The decision for a prostate biopsy on patients with a PSA between 4-10 ng/ml with free/total ratio < 20% continues to be an issue, however, we can optimize decision using other parameters such as prostate volume, PSA density and bioavailable testosterone/prostate volume

Utilidad de la criobiopsia en el diagnóstico de la enfermedad pulmonar intersticial difusa: análisis de rentabilidad y coste / Cryobiopsy in the Diagnosis of Diffuse Interstitial Lung Disease: Yield and Cost-Effectiveness Analysis

Introducción: En los pacientes con enfermedad pulmonar intersticial difusa (EPID) que presentan datos clínicos y radiológicos inconsistentes es recomendable la realización de una biopsia pulmonar quirúrgica (BPQ). La criobiopsia es una técnica endoscópica reciente menos invasiva que la BPQ que podría jugar un papel relevante en el diagnóstico de las EPID. El objetivo del presente estudio es analizar la rentabilidad diagnóstica, las complicaciones y los costes económicos derivados del uso de la criobiopsia en el diagnóstico de las EPID. Métodos: Estudio observacional retrospectivo en el que se incluyeron pacientes afectados de EPID tributarios de biopsia pulmonar, a los que se les practicaron criobiopsias desde enero de 2011 a enero de 2014. El procedimiento se realizó mediante videobroncoscopio, bajo anestesia general y ventilación mecánica. Se analizó la rentabilidad diagnóstica, las complicaciones producidas y los costes económicos derivados de esta técnica. Resultados: Se analizaron las muestras de criobiopsia de un total de 33 pacientes. Se obtuvo un diagnóstico específico en 26, lo que representa una rentabilidad diagnóstica del 79%. Cinco pacientes hubieran requerido BPQ para confirmación histológica, aunque en 4 de ellos no pudo realizarse por presentar comorbilidades graves. Las complicaciones más frecuentes fueron el neumotórax (12%) y el sangrado moderado (21%). No hubo complicaciones graves. Considerando que a los pacientes con diagnóstico específico se les evitó unaBPQ, la criobiopsia representó unahorro económico estimado dehasta 59.846 Euros. Conclusiones: La criobiopsia es una técnica segura y potencialmente útil en el diagnóstico de las EPID que permite, además, un ahorro económico considerable

Background: Assessment of patients with suspected interstitial lung disease (ILD) includes surgical lung biopsy (SLB) when clinical and radiological data are inconclusive. However, cryobiopsy is acquiring an important role in the ILD diagnostic process. The objective of this study was to evaluate the diagnostic yield, safety and economic costs of the systematic use of cryobiopsy in the assessment of patients with suspected ILD. Methods: This was a retrospective observational study of patients who had undergone transbronchial cryobiopsy for evaluation of ILD from January 2011 to January 2014. The procedures were performed with a video bronchoscope using a cryoprobe for the collection of lung parenchyma specimens, which were analyzed by pathologists. Diagnostic yield, complications and economic costs ofthis technique were analyzed Results: Criobiopsy specimens from a total of 33 patients were included. A specific diagnosis was obtained in 26, producing a diagnostic yield of 79%. In 5 patients, SLB was required for a histopathological confirmation of disease, but the procedure could not be performed in 4, due to severe comorbidities. The most frequent complications were pneumothorax (12%) and grade i (9%) or grade ii (21%) bleeding. There were no life-threatening complications. The systematic use of cryobiopsy saved up to 59,846 Euros. Conclusion: Cryobiopsy is a safe and potentially useful technique in the diagnostic assessment

Consideraciones clínicas de la expresión de P504S y metaloproteinasa de matriz 2 en células prostáticas circulantes en sangre diseminadas como resultado de una biopsia prostática trans-rectal guiada por ecografía / Expression of P504S and matrix metalloproteinase-2 in circulating prostate cells disseminated as a result of transrectal ultrasound guided biopsy as determined by immunocytochemistry: Clinical implications

OBJETIVO: la manipulación quirúrgica del cáncer tiene la potencialidad de aumentar la diseminación de células cancerosas al torrente sanguíneo y con esto el riesgo de metástasis. Presentamos el efecto de la biopsia prostática en la diseminación de estas células así como sus características fenotípicas. MÉTODOS: Se incluyeron cincuenta hombres que fueron sometidos a una biopsia prostática trans rectal como sospecha de cáncer de próstata en nuestro estudio. Se recolectaron muestras sanguíneas inmediatamente antes de la biopsia, una hora y 24 horas posterior a la misma, para detección de células prostáticas en sangre (CPC) así como para determinar sus características fenotípicas utilizando inmunocitoquímica estándar con anti PSA y luego caracterizarlas utilizando anti P504S y anti matriz de metaloproteinasa 2 (MMP-2). RESULTADOS: Catorce hombres (28%) tuvieron cáncer de próstata en la biopsia, 13 de estos fueron P504S + y MMP-2 + previo a la biopsia. Una hora posterior a la biopsia existió una mezcla de P504S + y P504S - así como de MMP2 + y MMP2 - en pacientes con biopsia positiva para cáncer, niveles que se igualaron a los pre biopsia luego de 24 horas. En pacientes negativos para cáncer, se detectaron células circulantes P504S - y MMP-2 -, algunas de ellas se mantuvieron por más de 24 horas. CONCLUSIONES: La biopsia prostática puede causar diseminación de células prostáticas malignas y benignas a la circulación y la mayoría son eliminadas dentro de las primeras 24 horas. No existió conversión de pacientes con cáncer de CPCs negativos a positivos lo que sugiere que la capacidad inherente de las células prostáticas de diseminar es más importante que el efecto de la biopsia prostática

OBJECTIVES: Surgical manipulation of cancer has been shown to increase blood borne cancer cell dissemination and increase the risk of metastasis. We present the effect of prostate biopsy on prostate cell dissemination and the phenotypic characteristics of these cells. METHODS: 50 men undergoing initial prostate biopsy for suspicion of prostate cancer were studied. Blood samples were taken immediately before, and 1 and 24 hours after biopsy for circulating prostate cells (CPC) determination and phenotypic characterization. CPCs were detected and counted using standard immunocytochemistry using anti-PSA and then characterized using anti-P504S and anti-matrix metalloproteinase-2 (MMP-2). RESULTS: 14 (28%) men had cancer detected on biopsy. 13/14 had P504S (+) and MMP-2 (+) cells detected prior to biopsy. One hour after biopsy there was a mixture of P504S (+) and P504S (-) cells detected, as well as MMP-2 (+) and MMP-2 (-) cells detected. 24 hours after biopsy the same 13/14 men remained positive, although the number of CPCs increased 1 hour after biopsy and then the numbers decreased to prebiopsy levels after 24 hours. In cancer negative men, P504S (-) and MMP-2 (-) cells were detected, some of these cells persisted 24 hours after biopsy. CONCLUSIONS: Prostate biopsy causes dissemination of prostate cells into the circulation, both malignant and benign; the majority of them are cleared within 24 hours. There was no conversion of negative to positive result in men with cancer, this suggests that the inherent capacity of malignant CPCs to disseminate is more important than the effect of dissemination caused by prostate biopsy

Awaiting diagnosis of breast cancer: strategies of enduring for preserving self.

PURPOSE/OBJECTIVES: To explicate the emotional experiences of women undergoing breast cancer diagnosis who are waiting for the results of breast biopsy. RESEARCH APPROACH: Glaserian Grounded Theory. SETTING: Urban area in western Canada. PARTICIPANTS: 37 women aged 32-76 years. The breast cancer diagnosis was positive for 11 women, negative for 24 women, and two results were unclear. METHODOLOGIC APPROACH: Unstructured, recorded telephone interviews. FINDINGS: Undergoing breast cancer diagnosis is a profoundly distressing experience dictated by diagnostic processes and procedures. Women rapidly transitioned from wellness to frightening phases of facing cancer to continuing terror during the testing phase. While waiting to hear results, women controlled their emotions, which enabled them to get through the experience and highlighted the protective function of enduring and its necessity for survival. The basic social psychological process, preserving self, is the outcome of enduring. CONCLUSIONS: A mid-range theory, Awaiting Diagnosis: Enduring for Preserving Self, was developed. This theory explicates the emotional responses of women who were undergoing diagnosis for breast cancer and provides a theoretical behavioral basis for responding to cues and signals of suffering. INTERPRETATION: The Praxis Theory of Suffering enables nurses to recognize and respond according to the behaviors of suffering, and to endure with healthy, adaptive, and normalizing behaviors that enable preserving self.

Pain and anxiety during bone marrow biopsy.

A bone marrow biopsy is considered to be painful, often causing anxiety. We observed large differences between patients and wondered which factors cause pain and anxiety. In a prospective study, 202 patients were analyzed. Experienced hematologists and fellows in training (17% of biopsies) performed bone marrow aspirates and biopsies from the posterior iliac crest. Demographics, disease category, performance score, source of information, number of previous biopsies, experience of the hematologist, and length and quality of the biopsy were recorded. Pain and anxiety were measured using a visual analog scale and verbal rating score. Data were subjected to univariate and multivariate regression. The median pain score was 1.9 (range 0-10); 21% did not experience any pain. Anxiety scored 1.8 (range 0-10), and correlated positively with pain (p = .000). By univariate analysis, young age, poor performance, the physician as source of information, and prolonged procedures were associated with more pain. In multivariate analysis, anxiety, information from the physician, and a prolonged procedure persisted. Length or artifacts of the core biopsy did not correlate with pain. In conclusion, bone marrow biopsies performed in an optimal setting by experienced hematologists cause only mild pain, with, however, some patients experienced serious problems. To reduce pain, not only careful local anesthesia, but also the addition of systemic analgesics and especially anxiety reduction seems to be useful.

Análisis de las complicaciones de la biopsia renal en el paciente trasplantado renal / Analysis of renal biopsy complications in renal transplant patients

Antecedentes: La biopsia renal es una técnica fundamental en el estudio de la patología del injerto renal. Es fundamental conocer sus complicaciones ya que es el procedimiento más agresivo por su morbimortalidad. Objetivos: El objetivo principal de nuestro estudio fue analizar e identificar las complicaciones clínicas derivadas de la biopsia renal percutánea en pacientes trasplantados renales. Evaluamos si algún factor clínico de los pacientes influye en la aparición de dichas complicaciones. Pacientes y Métodos: Se realizó un estudio observacional, retrospectivo de todos los pacientes a los que se les realizó una biopsia renal percutánea de injerto renal entre enero de 2009 y enero 2012. Se analizaron: edad, sexo, hipertensión arterial, creatinina sérica, proteinuria y hemoglobina previa y posterior a la biopsia. Definimos complicaciones menores (caída hemoglobina mayor 1 g/dl, hematuria macroscópica) y complicaciones mayores (necesidad de transfusión, cirugía, nefrectomía, arteriografía, embolización o muerte). Todas las biopsias se realizaron con control ecográfico. Resultados: El número de biopsias realizadas fue de 92. La edad media de los pacientes fue de 47.9 ± 13.2 años y el 70.7% eran hombres. Se observaron 2 complicaciones mayores (2.2%) y en ambas los pacientes presentaron sangrado y sepsis urológica, precisando uno de ellos de transfusión. Las complicaciones menores fueron del 14.1%. No se encontró ninguna pérdida del injerto ni muerte por biopsia renal. Conclusión: La biopsia percutánea en injerto renal realizada por médicos nefrólogos con experiencia y bajo control ecográfico en tiempo real, es un procedimiento con bajo riesgo, semejante al observado en riñón nativo. La cumplimentación cuidadosa de nuestro protocolo de biopsia renal, optimiza la relación riesgo beneficio de esta técnica (AU)

Background: Renal biopsy is a fundamental technique in the study of renal allograft pathology. It is essential to know its complications since it is the more aggressive procedure morbidity and mortality. Objectives: The main objective of our study is to analyze and identify clinical complications resulting from percutaneous renal biopsy in renal transplant patients. To assess whether a patient clinical factor influencing the onset of these complications. Patients and Methods: An observational, retrospective study of all patients who underwent percutaneous renal biopsy renal graft between January 2009 and January 2012. Were analyzed: age, sex, hypertension, serum creatinine, proteinuria and hemoglobin before and after the biopsy. We defined minor complications (hemoglobin drop greater than 1 g / dl) and major complications (requiring transfusion, surgery, nephrectomy, arteriography, embolization or death). The biopsy was performed by the nephrology team with ultrasound guidance and withdrawing the antiplatelet therapy. Results: The number of biopsies performed was 92. The mean age of patients was 47.9 ± 13.2 years and 70.7% were men. There were 2 major complications (2.2%) and both patients had urological bleeding and sepsis, one need a transfusion. Minor complications were 14.1%. The graft loss or patient death was not observed. Conclusion: Percutaneous renal graft biopsy performed by physicians experienced nephrologists under ultrasound guidance in real time, is a low risk procedure, similar to that observed in native kidney. The careful completion of our protocol renal biopsy, optimize the risk benefit ratio of this technique (AU)

Predictors of nonalcoholic steatohepatitis in obese children.

As the prevalence of childhood obesity increases, the incidence of nonalcoholic fatty liver disease and nonalcoholic steatohepatitis (NASH) also escalates. This study's purpose was to identify the clinical criteria to aid in determining when a liver biopsy is indicated for this growing population because currently no guidelines exist. We performed a retrospective chart review on all patients who were seen in the Nutrition Exercise and Weight Loss Kids™ Program at the Children's Hospital of Wisconsin from July 2003 through December 2004. We analyzed only individuals who underwent liver biopsy with the following criteria: (1) no evidence of other liver disease and (2) aspartate transaminase or alanine aminotransferase greater than 200 IU/L or any elevation of or for more than 6 months. Of the 284 patients reviewed, only eight patients (3%) met the criteria for analysis. Biopsy results demonstrated that 100% had histological evidence of NASH with steatosis, and seven of the eight (87.5%) had NASH with fibrosis, cirrhosis, or both. Obese children with an aspartate transaminase or alanine aminotransferase greater than 200 IU/L or any elevation of aspartate transaminase or alanine aminotransferase for more than 6 months, have a strong likelihood of having NASH with or without fibrosis, cirrhosis, or both.

Nurse practitioner-led prostate biopsy in the United Kingdom.

As prostate cancer detection rates increase, multi-professional health care teams with nurse practitioners are adopting some roles that have predominantly been in the medical domain. This article reports the development of nurse practitioners undertaking prostate biopsies in the United Kingdom and presents an audit demonstrating the safety of nurse practitioners conducting this procedure.
