[Daniela Ramírez Castillo MD. (She/her) @DanielaRamMD]

Excited to be applying this year to EM, so it’s time to reintroduce myself! I’m Daniela, a 🇨🇴 physician with experience in HIV care and taking care of underserved communities. I work as a clinical research coordinator at the emergency department in NYC. #EMbound #Match2025

Selva has gastric cancer and would like to join a clinical trial with zolbetuximab. If anyone can guide her towards someone working on a clinical trial that may align, it would be great!

[🚨 POR FAVOR AYÚDAME A DIFUNDIR — BUSCO UN ENSAYO CLÍNICO EN CUALQUIER PARTE DEL MUNDO 🌍]

Mi nombre es Selva Alvarez, tengo 35 años, vivo en Colombia y soy Científica de Datos 📊. Hoy no les escribo solo como una paciente con cáncer gástrico avanzado (Estadio IV) 🎗️, sino como alguien que acaba de encontrar un dato científico único en su propio cuerpo que podría cambiarlo todo 🧬.

Ayer, 21 de mayo de 2026, mi reporte de patología reveló algo extraordinario y muy escaso en el mundo: mi tumor dio POSITIVO para una proteína llamada CLAUDINA 18.2 🔬.

Para explicarlo de forma sencilla: la Claudina 18.2 es como una "cerradura" 🔐 muy rara que solo tienen algunos tumores en el mundo. La ciencia médica ya inventó una "llave" 🔑 exacta para esa cerradura (un medicamento avanzado llamado Zolbetuximab o Vyloy), que es capaz de atacar directamente las células enfermas sin destruir el resto del cuerpo 🎯.

El problema es que este medicamento no es comercial en Colombia 🇨🇴. Mi oncólogo me confirmó que mi única oportunidad real de acceder a esta "llave" es que una farmacéutica o un centro de investigación me reciba en un Ensayo Clínico Nacional o Internacional o en un programa de acceso expandido ✈️.

Al ser un perfil de paciente tan escaso y específico en el planeta, sé que hay laboratorios y científicos en el mundo buscando activamente a personas como yo para sus estudios de medicina de precisión 🩺.

Quiero que el mundo sepa que estoy lista 💪: mis órganos vitales (hígado y riñones) están completamente sanos, fuertes y funcionando a la perfección, listos para resistir el tratamiento 🫁. Tengo la juventud, la fuerza biológica y la determinación absoluta de pelear por mi vida y aportar a la ciencia 🦾.

Hago un llamado directo a la comunidad científica global (#OncoTwitter 🩺), a laboratorios como @AstellasUS 🏢, y a investigadores de cualquier país que lideren estudios sobre Claudina 18.2: Aquí hay una paciente joven con el biomarcador idóneo 📑.

Por favor, ayúdenme con un RT (compartir) 🔁. Un solo clic de ustedes puede hacer que este mensaje cruce fronteras y llegue al comité científico o a la farmacéutica que me pueda patrocinar 💌.

Mis mensajes directos (DM) están abiertos para enviar de inmediato mi historial médico, resultados de los marcadores, bloques de patología o cualquier cosa que se necesite 📤.

Colombia 🇨🇴 | Contacto: DM abierto 📩.

For All IMG, PD's, and fellow co residents: Today is the last day to submit your comments to the DOS regarding the proposal of limiting J1 visa to a max of 4 year. https://t.co/DtfTaUBhhY 🚩🚩

In @ProjectImg we are launching this new campaign showing from the words of AMGs how much IMGs are needed in this country and the importance of international doctors across the nation, specially serving the most underserved communities!

In places where getting one appointment with a Primary care doctor can take up to 1 year!!!

We are all colleagues and we are all working together for the good of our patients and communities! 🤍🩵🙌

[Daniela Ramírez Castillo MD. (She/her) @DanielaRamMD]

I will be taking over @ProjectImg’s Instagram stories this Thursday to answer any questions you may have about my USMLE/residency application journey! Feel free to ask anything.

I cried for literally one hour. I can’t believe I finally made it here! I had to make to many sacrifices throughout my journey and it was ALL WORTH IT!

[Justin Blankenbaker, DO, MPH, AMOE @NotoriousS1Q3T3]

Unfortunately I did not Match into Emergency Medicine, and I am absolutely devastated. 😭 I will be trying to secure an unfilled spot in the SOAP. I welcome any support and thoughts as I continue to work towards this goal.
