glioblastoma fisiopatologia

En un trabajo publicado sobre la población de Gironde en Francia, se ha observado un incremento desde 1980. This can also make it difficult to fully remove glioblastoma tumors during surgery without harming surrounding healthy brain tissue. It's a very fast-growing tumor that tends to spread to nearby normal brain tissue. El tratamiento quimioterápico, particularmente con nitrosoureas, se ha mostrado sólo parcialmente eficiente. clinically relevant subtypes of glioblastoma characterized by abnormalities in Symptoms may start to appear at any time in life. [67] The overall benefit of anti-angiogenic therapies as of 2019 is unclear. 2011. The new 2016 WHO Classification of Tumors of the Central Nervous System[29] was a paradigm shift: some of the tumors were defined also by their genetic composition as well as their cell morphology. Su incidencia es de 3-4 casos por 100.000 habitantes por año. Astrocytes are star-shaped, so glioblastomas are infiltrative in nature and develop tentacles that can spread disease to other parts of the brain. [citation needed], GBMs usually form in the cerebral white matter, grow quickly, and can become very large before producing symptoms. Los datos de tres registros de cáncer demuestran un aumento de la incidencia de glioblastomas en el lóbulo frontal, lóbulo temporal, y el cerebelo, y una reducción de la incidencia en otras regiones del cerebro. For other diseases, symptoms may begin any time during a person's life. Comparar los datos entre los registros es difícil y requiere, herramientas de diagnóstico. Los síntomas son diversos, varían según la ubicación, y se manifiestan como déficits neurológicos focales, encefalopatía o convulsiones. El oligodendroglioma se clasifica en dos grados según sus características. We are the first and only national nonprofit focused on fighting glioblastoma and improving patient outcomes. Estos tumores están asociados con el tiempo de supervivencia más baja, que es de 1-2 años. A pesar de este tratamiento agresivo, la mediana de supervivencia se mantiene aproximadamente en 14 meses. Patients with a methylated MGMT promoter have longer survival than those with an unmethylated MGMT promoter, due in part to increased sensitivity to temozolomide. Journal of Pediatric Hematology/Oncology: Official Journal of the American Society of Pediatric Hematology/Oncology (Junio 2). In most cases, the exact underlying cause is unknown; however, they can rarely occur in people with certain genetic syndromes such as neurofibromatosis type 1, Turcot syndrome and Li Fraumeni syndrome. We support the development of new drugs and other effective therapies for glioblastoma. Call us at 919-402-1775 or email us at info@glioblastomafoundation.org. If you have questions about a glioblastoma diagnosis, we’re here to provide resources about clinical trials and other treatment options. “Postoperative deterioration in health related quality of life as predictor for survival in patients with glioblastoma: a prospective study.” PloS One 6 (12): e28592. [citation needed], Distinguishing primary glioblastoma from secondary glioblastoma is important. [82], About three per 100,000 people develop the disease a year,[3] although regional frequency may be much higher. El vector P 111In/90Y-DOTAGA se une a estos receptores y puede ser utilizado para el tratamiento local de tumores cerebrales (Kneifel 2007). “Descriptive epidemiology of cerebral gliomas in northwest Greece and study of potential predisposing factors, 2005-2007.” Neuroepidemiology 33 (2): 89-95. doi:10.1159/000222090. doi:10.1016/j.wneu.2011.05.05, Excepto donde se indique lo contrario, el contenido de este wiki esta bajo la siguiente licencia:CC Attribution-Share Alike 4.0 International. More likely to nap or to phase in and out of sleep. [citation needed], The cause of most cases is unclear. Glioblastoma can occur at any age, but tends to occur more often in older adults. [76], Increasing age (> 60 years) carries a worse prognostic risk. Los síntomas generales, comunes a todos los tumores, son dolor de cabeza y vómitos. GARD is not currently aware of a specialist directory for this condition. [86], Gene therapy has been explored as a method to treat glioblastoma, and while animal models and early-phase clinical trials have been successful, as of 2017, all gene-therapy drugs that had been tested in phase-III clinical trials for glioblastoma had failed. Tumors of this type usually arise from the cerebrum and may exhibit the classic infiltration across the corpus callosum, producing a butterfly (bilateral) glioma.[26]. Cancer cells in GBM tumors rapidly multiply. Common symptoms of problems in the nervous system include trouble moving, speaking, swallowing, breathing, or learning. Methylation impairs DNA transcription and expression of the MGMT gene. CA Cancer J Clin 2010;60:277e300. transitorias por obstrucción de vasos. It grows fast and can spread quickly, so by the time it’s diagnosed, the chances for survival are low. The results of a pilot study on the use of THC in end-stage patients with recurrent glioblastoma appeared worthy of further study. Cancer Cell 2010;17:98e110. La tinción para detectar la proteína acida fibrilar de la neuroglía es positiva en la mayoría de los astrocitomas (sin embargo, es probable que no sea positiva en algunos gliomas indiferenciados y en los astrocitomas gemistocíticos, porque es necesario que haya astrocitos fibrilares para que el resultado sea Además, el médico puede explorar el fondo de ojo (retina) y encontrar lo que se denomina "edema de papila", que indica que el cerebro está sometido a una mayor presión de la normal. En el estudio aleatorizado controlado con placebo multicéntrico de fase III, sobre cirugía guiada por fluorescencia con ácido 5-aminolevulínico (5-ALA) en el glioma maligno, la radicalidad quirúrgica fue aún más estricta utilizando valores absolutos para la estimación del volumen del tumor residual. [36], Long-term benefits have also been associated with those patients who receive surgery, radiotherapy, and temozolomide chemotherapy. “[Biology molecular of glioblastomas].” Neurocirugía (Asturias, Spain) 18 (5) (October): 373-382. [77], A good initial Karnofsky performance score (KPS) and MGMT methylation are associated with longer survival. 2do tipo de cáncer más frecuente en niños. a common feature of glioblastoma. Es uno de los tumores mas vascularizados ya que expresa VEGF y factores proangiogénicos. simultáneos de los lóbulos frontal y temporal, E.comisura intertalámica —> gliomas Here’s a closer look at Glioblastoma and what every patient and loved one needs to know. Doctors, other trusted medical professionals, and patient organizations may also be aware of studies. [58] A total radiation dose of 60–65 Gy has been found to be optimal for treatment.[59]. Survival is poor with approximately 40% survival in the first year post diagnosis and 17% in . El glioblastoma es el tumor cerebral más frecuente, 20 representando aproximadamente el 12-15 % de todas las neoplasias intracraneales y el 50-60 % de todos los tumores astrocitarios. They take a team approach, with neurosurgeons, neuro-oncologists and radiation oncologists working together to coordinate your care and deliver the best therapies . Estes feixes de radiação agem diretamente no local do tumor, matando as . The 2007 WHO Classification of Tumors of the Central Nervous System[28] was the last classification mainly based on microscopy features. “[Epidemiology of Glioblastoma].” Neuro-Chirurgie 56 (6) (December): 433–440. Although this study was still in clinical trials in 2017, it has shown diagnostic and therapeutic functionalities, and will open great interest for clinical applications in stem-cell-based therapy. http://www.ncbi.nlm.nih.gov/pubmed/22331317. Virus de la Enfermedad de Newcastle como nueva aproximación terapéutica para el glioblastoma. Por el contrario, p53, en el cromosoma 17, no se mostró afectado. Un subtipo, se caracteriza por la amplificación frecuente o mutaciones en el receptor del factor de crecimiento epidérmico del protooncogen (EGFR). Some organizations build a community of patients and families impacted by a medical condition, like epilepsy, or related conditions, like heart problems, that may also be a symptom in other diseases. Cerca de 30% de todos os tumores cerebrais são gliomas. Se observan astrocitos gemistocíticos sólo en los astrocitomas gemistocíticos y en los glioblastomas multiformes. Help us transform the standard of care for Glioblastoma! De su mutación o inhibición puede desencadenarse la aparición de tumores, por ejemplo, de próstata, mama, colon y cerebro. OBJETIVO: Analisar a relação do déficit motor com a topografia do GBM. Los hallazgos histológicos asociados a estos tumores son (es posible que no todos estén presentes; esta lista no sigue ninguno de los sistemas convencionales de clasificación ya mencionados): • neovascularización con proliferación endotelial, • células en seudoempalizada que rodean las áreas de necrosis. [77] A DNA test can be conducted on glioblastomas to determine whether or not the promoter of the MGMT gene is methylated. Sadly, there have also been relatively . [14][21][22], The cellular origin of glioblastoma is unknown. Los corticosteroides siguen siendo el pilar para el manejo del edema cerebral causado desde la década de 1960 aunque el uso crónico puede causar un síndrome de Cushing iatrogénico (Wheeler y col., 2011). La resección seguida de radioterapia se asocia con una supervivencia más larga que la radioterapia con biopsia sola (Devaux y col., 1993). Conceptos clave Los gliomas son tumores primarios que se originan en el parénquima encefálico. El glioblastoma afecta con mayor frecuencia a adultos mayores, con un pico de incidencia entre la quinta y septima década, es más común en hombres que mujeres 1,6 veces, y en personas de raza blanca 2 veces más que raza negra(2,3). El grado de resección actúa sinérgicamente con la radioquimioterapia concomitante y adyuvante, especialmente en pacientes con la metilación del promotor MGMT (Stummer y col., 2012). This characteristic, as well as the presence of hyperplastic blood vessels, differentiates the tumor from grade 3 astrocytomas, which do not have these features. This symptom is known as intracranial pressure.

Los glioblastomas son tumores astrocíticos malignos (de grado IV según la clasificación de la Organización Mundial de la Salud (OMS)). Glioblastoma y Astrocitoma Maligno - American Brain Tumor Association Neoadjuvant targeting of glioblastoma multiforme with radiolabeled DOTAGA-substance P-results from a phase I study. meníngeas y ventriculares con una frecuencia [20] Similarly, exposure to radiation during medical imaging, formaldehyde, and residential electromagnetic fields, such as from cell phones and electrical wiring within homes, have been studied as risk factors. PubMed The results of this research could open to possible therapies with drugs that inhibit this protein, such as crizanlizumab. This section is currently in development. El término glomerulonefritis rápidamente progresiva (GNRP) hace referencia a un evento clínico caracterizado por deterioro de la función renal que cursa en días o semanas y que, dejado a su natural evolución, produce insuficiencia renal terminal en la mayoría de los pacientes. Experiencing headaches that may indicate increased swelling. El origen étnico, edad, sexo, síndromes hereditarios, algunos polimorfismos constitutivos, y la irradiación del cerebro son importantes factores de riesgo. [6], Another important alteration is methylation of MGMT, a "suicide" DNA repair enzyme. We’re also making strides to improve neurosurgical techniques and therapeutic treatments for glioblastoma. By the time symptoms appear and a patient consults their doctor, glioblastoma can be advanced. 2011. E por fim a SIADH é uma doença em que a excreção de água é prejudicada pela incapacidade de suprimir a secreção de ADH. Infatti, le cellule tumorali necessitano della presenza di vasi sanguigni per: l’apporto di ossigeno e nutrienti, l’eliminazione dei materiali di scarto e la formazione di nicchie vascolari per il supporto selettivo delle cellule staminali[3], Lo sviluppo dei vasi sanguigni è regolato dal bilancio tra molecole pro- e anti-angiogeniche[3], Il principale fattore pro-angiogenico è il VEGF che, attraverso l’attivazione del VEGFR-2, regola la sopravvivenza, la proliferazione, la migrazione e la permeabilità delle cellule endoteliali, Nel glioblastoma il VEGF è affiancato da diversi altri fattori pro-angiogenici, a cui si contrappongono fattori anti-angiogenici. Pacientes en mal estado para anestesia general. Franco-Hernández, C, V Martínez-Glez, and J A Rey. In retrospective analyses, removal of 98% or more of the tumor has been associated with a significantly longer healthier time than if less than 98% of the tumor is removed. Neuro-oncol 2008;10:1025-1034. The current standard of care for glioblastoma is comprised of surgery, chemotherapy, and radiation. [6][13] About 3 in 100,000 people develop the disease per year. F.B. We would like to hear your feedback as we continue to refine this new version of the GARD website. Los reingresos en los primeros 30 días tuvieron una supervivencia significativamente más corta Radiotherapy plus concomitant and adjuvant temozolomide for glioblastoma. Los glioblastomas son poco frecuentes en los niños (0,6-7,9 % de todos los glioblastomas), y el pronóstico es mejor que la de los glioblastomas observados en adultos (Márquez-Rivas 2010; Khalatbari y col., 2011). Neurosurgery. Despite aggressive multimodal treatment approaches, the overall survival period is reported to be less than 15 months after diagnosis. [citation needed], The greater the extent of tumor removal, the better. Un estudio publicado en julio de 2011 en el Journal of Neurosurgery, los autores encontraron una ventaja de supervivencia significativa en resecciones subtotales con una extensión de resección de tan sólo el 78%, con una mejora gradual en la supervivencia a partir de allí e incluso en el rango del 95% -100% (Sanai y col., 2011). El glioblastoma mesenquimal presenta deleción 17q11.2, región que codifica en gen NF1, así como marcadores mesenquimales. O glioblastoma multiforme (GBM) é o tumor glial com maior grau de malignidade. Only tumors that are IDH wild type are now classified as glioblastoma. Cancer Cell 2006;9:157e73. Several viruses including herpes simplex virus, adenovirus, poliovirus, and reovirus are currently being tested in phases I and II of clinical trials for glioblastoma therapy and have shown to improve overall survival. Nguyen, Van, Jesse M Conyers, Dongqin Zhu, Denise M Gibo, Jay F Dorsey, Waldemar Debinski, and Akiva Mintz. A risk factor known to be associated with glioblastoma is prior ionizing radiation therapy that uses high energy waves/particles to . La fisiopatología es una rama de la medicina que estudia los mecanismos por los cuales se originan las distintas enfermedades. [25] The tumor may extend into the meninges or ventricular wall, leading to high protein content in the cerebrospinal fluid (CSF) (> 100 mg/dl), as well as an occasional pleocytosis of 10 to 100 cells, mostly lymphocytes.

As part of the Glioblastoma Foundation's focus on drug repurposing, several drugs currently on the market for other conditions have been identified that may provide hope to glioblastoma patients in the future. Os gliomas são tumores primários originados no parênquima cerebral. Presenta dos variedades: el glioblastoma de células gigantes y el gliosarcoma. 2011. [1] Surgical removal (decompression) of the tumor is linked to increased survival, but only by some months. Glioblastoma multiforme (GBM) is a rare cancer that starts in the brain. Among others, it increases the glioblastoma cells' dependence on glutamine or glutamate as an energy source. The tumor can start producing symptoms quickly, but occasionally is an asymptomatic condition until it reaches an enormous size. Most studies show no benefit from the addition of chemotherapy. [68], Alternating electric field therapy is an FDA-approved therapy for newly diagnosed[69] and recurrent glioblastoma. en los núcleos básales invaden el centro Despite research efforts and progress in neu-roimaging, neurosurgery, radiation and chemotherapy, the overall survival of patients with this disease has changed little over the past 30 years. doi:10.1177/0883073811428007. Alta letalidad: 7% de supervivencia a 5 años. Glioblastoma Foundation supports the development of targeted therapies for glioblastoma. Los gliomas de alto grado se clasifican en grado tres y cuatro y según Kernohan el grado 3 presenta atipias celulares mitosis y proliferación endotelial vascular. Aunque esto puede representar un sesgo, la causa de estas tendencias observadas es desconocida (Zada y col., 2011). doi:10.1007/s10014-012-0084-2. El glioblastoma es un tipo de cáncer agresivo que se genera en el cerebro o la médula espinal. Cancer statistics, 2010. Glioblastomas are often very aggressive and grow into surrounding brain tissue. En 1926, una publicación de P. Bailey y H. Cushing volvió a proponer, con éxito, la expresión de Mallory. If you would like to contribute to our mission, your donation will directly fund the development of novel therapies for glioblastoma. Research also helps doctors better understand how well a treatment works and can lead to new treatment discoveries. Whole-brain radiotherapy does not improve when compared to the more precise and targeted three-dimensional conformal radiotherapy. Grado III: oligodendroglioma maligno .

Symptoms can vary widely from patient to patient but can include headaches or neck pain, changes in vision, nausea, disorientation, and difficulties speaking. • Glioblastoma (segundo más frecuente de primarios). En la primera mitad del siglo XIX el glioblastoma se consideraba de origen mesenquimal y por tanto se definió con el término de sarcoma. [91], Oncolytic virotherapy is an emerging novel treatment that is under investigation both at preclinical and clinical stages. los gliomas de alto grado provocan siembras Los gliomas Grados I y II son benignos y los Grados III y IV son más agresivos o malignos. Glioblastoma is a highly malignant brain tumor that arises from astrocytes, the supportive cells in the nervous system. Motomura, Kazuya, Atsushi Natsume, Yugo Kishida, Hiroyuki Higashi, Yutaka Kondo, Yoko Nakasu, Tatsuya Abe, Hiroki Namba, Kenji Wakai, y Toshihiko Wakabayashi. Mallory, en una memoria de 1914, propuso el término glioblastoma multiforme. Estas alteraciones pueden tomar la forma de modificaciones epigenéticas, mutaciones puntuales, translocaciones, ampliaciones o supresiones y modificar las funciones de los genes de una manera que desregulan las vías de señalización celular que conducen al fenotipo del cáncer (Stratton y col., 2009). 2011. Abstract Glioblastoma multiforme is the most common primary brain tumour in adults. La combinación de la amplificación gen-EGFR y pérdida de heterozigosidad (LOH)del cromosoma 10, son de peor pronóstico. “Resection, Biopsy, and Survival in Malignant Glial Neoplasms. Glioblastoma, previously known as glioblastoma multiforme ( GBM ), is one of the most aggressive types of cancer that begin within the brain. [6] [better source needed] Initially, signs and symptoms of glioblastoma are nonspecific. It can occur at any age but generally impacts older adults. Clinical article. Artigo em Inglês | MEDLINE | ID: mdl-7892958 18. Microscopically, glioblastoma multiforme is characterized by regions of pseudopalisading necrosis, pleomorphic nuclei and cells, and microvascular proliferation. Because these organizations include the life experiences of many different people who have a specific disease, they may best understand the resources needed by those in their community. doi:10.3171/jns.1993.78.5.0767. La radioterapia local con (213)Bi-DOTA-[Thi (8),Met(O (2)) (11)]-substance P es factible y puede representar un tratamiento innovador y eficaz para los gliomas de áreas elocuentes (Cordier 2010). Otros factores de riesgo son discordantes o no se confirmaron debido a las limitaciones metodológicas. We had a private room for five days we slept with her and held her hand a lot comforting her. [12] Complete cures are extremely rare, but have been reported. 3. Glioblastoma Treatment. All Rights Reserved. The Glioblastoma Foundation is working very hard to improve the outcome for patients and change this devastating disease into a manageable chronic condition. Rare disease umbrella organizations focus on improving the lives of all those impacted by rare diseases through education and advocacy efforts. GBMs increase in frequency with age and affect more men than women. Glioblastoma can: Invade and destroy brain tissue Put pressure on nearby tissue Take up space and increase pressure within the skull. ", "Formulations for Intranasal Delivery of Pharmacological Agents to Combat Brain Disease: A New Opportunity to Tackle GBM? [6] Primary glioblastomas have a worse prognosis and different tumor biology, and may have a different response to therapy, which makes this a critical evaluation to determine patient prognosis and therapy. Os sintomas são diversos e variam de acordo com a localização, manifestando-se como déficits neurológicos focais, encefalopatia ou convulsões. [102] It is estimated that more than 10,000 individuals in the United States will succumb to glioblastoma every year. RB (RetinoBlastoma tumor suppressor gene, Proteína del retinoblastoma). [65] High doses of temozolomide in high-grade gliomas yield low toxicity, but the results are comparable to the standard doses. Older adults also tend to receive less aggressive therapy, which may . Current clinical studies can be found by using ClincalTrials.gov. La mayoría de los gliomas de bajo grado no se observan con refuerzo ni en la TC ni en la RM (aunque algunos autores opinan que hasta 40% presenta refuerzo, en cuyo caso probablemente tengan peor pronóstico). Sin embargo, dado el hecho de que las complicaciones se produjeron con mayor frecuencia en el grupo de 5-ALA se precisarían estudios ajustados a riesgo (Stummer y col., 2011). Donations from fans, family, and friends allowed the Glioblastoma Foundation to establish this unique annual research award to encourage neurosurgeons to innovate surgical techniques and therapeutic methods for glioblastoma. Journal of Neuro-Oncology (Marzo 10). [3] The typical duration of survival following diagnosis is 10–13 months, with fewer than 5–10% of people surviving longer than five years. [87][88][89] Scientists have developed the core–shell nanostructured LPLNP-PPT (long persistent luminescence nanoparticles. Okita, Yoshiko, Yoshitaka Narita, Yasuji Miyakita, Makoto Ohno, Shintaro Fukushima, Takamasa Kayama, and Soichiro Shibui. Treatment of primary brain tumors consists of palliative (symptomatic) care and therapies intended to improve survival. Los tumores cerebrales que se originan en el propio cerebro se denominan primarios y los denominados secundarios, es decir, los que llamamos metastásicos, son aquellos tumores que se originan en otra parte del organismo como por ejemplo el pulmón o la mama u otro origen y que en algún momento de su evolución se extienden al cerebro. Stummer, Walter, Thomas Meinel, Christian Ewelt, Peter Martus, Olga Jakobs, Jörg Felsberg, and Guido Reifenberger. Although missions of organizations may differ, services may include, but are not limited to: What do disease-specific organizations do? 16 En la mayoría de países de Europa y de América del Norte, la incidencia es de 2-3 nuevos casos al año por cada 100 000 habitantes. After the death of John McCain, the U.S. Senate voted unanimously to designate the third Wednesday in July as Glioblastoma Awareness Day, bringing much-needed attention to this disease. Glioblastoma is one of the most common and detrimental forms of solid brain tumor, with over 10,000 new cases reported every year in the United States. ; 3 Centre for Population Health Sciences, The Usher Institute of Population Health Sciences and Informatics, Primary Palliative Care Research Group, University of Edinburgh . http://www.ncbi.nlm.nih.gov/pubmed/20523247. [49][50], When viewed with MRI, glioblastomas often appear as ring-enhancing lesions. del líquido cefaloraquídeo así como la Glioblastoma is a very aggressive form of brain cancer, and currently, there is no cure. Refuerzo en anillo de los glioblastomas multiformes: el centro de hipodensidad que se observa en la TC representa la necrosis. A día de hoy se sabe que el glioblastoma representa el 12-15% de las neoplasias intracraneanas y el 60-75% de los tumores astrocíticos. hidrocefalia por obstrucción del líquido It was previously known as glioblastoma multiforme, abbreviated GBM . [85], The term glioblastoma multiforme was introduced in 1926 by Percival Bailey and Harvey Cushing, based on the idea that the tumor originates from primitive precursors of glial cells (glioblasts), and the highly variable appearance due to the presence of necrosis, hemorrhage, and cysts (multiform). Los estudios de pérdida de heterozigosidad (LOH) constituyen el método más ampliamente usado, desde el 1 General 2 Macroscopy 3 Microscopic 3.1 Images 4 IHC 5 Molecular 6 See also 7 References General Median survival is measured in months. We support the development of new drugs and other effective therapies for glioblastoma. a multivariate analysis of 416 patients with glioblastoma multiforme: prognosis, extent of resection, and survival. [97], The efficacy of cannabinoids (cannabis derivatives) is known in oncology (through capsules of tetrahydrocannabinol (THC) or the synthetic analogue nabilone), on the one hand to combat nausea and vomiting induced by chemotherapy, on the other to stimulate appetite and lessen the sense of anguish or the actual pain. El tratamiento actual consiste en la resección quirúrgica máxima seguida de radioterapia y temozolomida ( Stupp y col., 2005, Stupp y col., 2009). Typical Age Range: GBs may . J Neurosurg 2011;114:613-623. doi:10.1016/j.neuchi.2010.07.011. Algunos gliomas malignos se observan sin refuerzo. Registrati ora per accedere ai contenuti dell'Area Riservata, Negli ultimi decenni si è andato affermando il concetto che il glioblastoma sia l’endpoint fenotipico comune di diversi processi genetici. For some diseases, symptoms may begin in a single age range or several age ranges. Causes. Puede aparecer como tumor primario o, más frecuentemente, como metástasis de otro cáncer. Historically, around 90% of patients with glioblastoma underwent anticonvulsant treatment, although only an estimated 40% of patients required this treatment. (GBM) foi maior em homens em 7:2. Rarely, the cancer spreads outside the brain to other parts of the body. Older adults with glioblastoma have a worse prognosis compared with younger patients [ 1 ]. Affiliations 1 Department of Neurosurgery, Oxford University Hospitals NHS Foundation Trust, Oxford OX3 9DU, UK chris.mckinnon@nhs.net.
