On the 29th of August we organised a PriNose successful mini-symposium!

In August, we finished screening in Paraguayan prisons. In total, we included 3820 participants! That was a reason to celebrate and to exchange the knowledge gained during this study. We did this in a mini-symposium, where over 20 people joined (both online and in-person). Amongst them were professors, doctors, people from CAD4TB, secondees who did their secondment last year, Paraguayan secondees currently staying in the Netherlands and Dutch secondees who are soon travelling to Paraguay. They all had one goal: learning from each other.


The programme was diverse, with talks from the epidemiologist from the National TB Programme Paraguay (Angelica Medina), the investigator and PhD student of the PriNose study (Luis Gomez), an old secondee and medicine student (Floryn Schippers), and the leading  radiologist of the PriNose study (Marlene Salina).  


To celebrate this fruitful symposium, we had a lovely dinner in the historic city centre of Nijmegen. Thank you all for joining!

Watch the mini-documentary and see the study team in action!

Mass screening of TB in Paraguayan prisons: that is what our research team did in the PriNose study. In August, we finished the screening phase, which means that we included a total of 3820 (!!!) persons deprived of liberty, distributed over 4 Paraguayan prisons. Do you want to see how they did that? Watch the video, made by the volunteer prisoners!

Personal stories of our study team

Why are our researchers and healthcare professionals working in the PriNose study? What does the work mean for them? And what is in their opinion the importance of the PriNose study?

Listen to their personal stories below (in Spanish).


Radiographist in the PriNose

Marlena is the lead in the rediography work of the PriNose. Before this, she worked as a cleaner in the National TB Program in Asuncion, but she turned out to have a history in radiography and now is extremely competent in our study team! She tells us: "Para mi, hablar de PriNose es hablar de cambio" ("For me, talking about the PriNose is talking about change"). Listen to her personal story by clicking on the video.


Tuberculosis screening with Aeonose and CAD4TB® in Paraguayan prisons

Tuberculosis in Paraguay

Tuberculosis is one of the main causes of death by infectious diseases in Paraguay. Tuberculosis is especially prevalent in crowded places with poor living conditions and bad ventilation. Prisons are an example of such places. The prevalence of TB in Paraguayan prisons is estimated to be 100 times higher than the national prevalence. 

The research

The aim of the World Health Organization (WHO) "End TB Strategy" is to end the global pandemic by 2035. If we want to achieve that, we need better diagnostic techniques to improve screening of high-risk populations.


This study researches TB the AeoNose™ (an electronic nose device) and CAD4TB® (chest X-ray with computed automated detection) in a specific high-risk population: prisons in Paraguay. The study population will consist of prisoners and prison employees. 

After providing informed consent, this study will systematically screen prisoners and its employees for TB, with the AeoNose™ and CAD4TB® and compare them with the gold standard for TB, a mycobacterial culture. 

You'll find a video about the procedure of the informed consent here.
