Abstract
The success of screening programs depends to a large extent on the adherence of the target population, so it is therefore of fundamental importance to develop computer simulation models that make it possible to understand the factors that correlate with this adherence, as well as to identify population groups with low adherence to define public health strategies that promote behavioral change. Our aim is to demonstrate that it is possible to simulate screening adherence behavior using computer simulations. Three versions of an agent-based model are presented using different methods to determine the agent's individual decision to adhere to screening: (a) logistic regression; (b) fuzzy logic components and (c) a combination of the previous. All versions were based on real data from 271,867 calls for diabetic retinopathy screening. The results obtained are statistically very close to the real ones, which allows us to conclude that despite having a high degree of abstraction from the real data, the simulations are very valid and useful as a tool to support decisions in health planning, while evaluating multiple scenarios and accounting for emergent behavior.

Acute venous thromboembolism plasma and red blood cell metabolomic profiling reveals potential new early diagnostic biomarkers: observational clinical study. J Transl Med 2024; 22:200.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a leading cause of cardiovascular mortality. The diagnosis of acute VTE is based on complex imaging exams due to the lack of biomarkers. Recent multi-omics based research has contributed to the development of novel biomarkers in cardiovascular diseases. Our aim was to determine whether patients with acute VTE have differences in the metabolomic profile compared to non-acute VTE. METHODS This observational trial included 62 patients with clinical suspicion of acute deep vein thrombosis or pulmonary embolism, admitted to the emergency room. There were 50 patients diagnosed with acute VTE and 12 with non-acute VTE conditions and no significant differences were found between the two groups for clinical and demographic characteristics. Metabolomics assays identified and quantified a final number of 91 metabolites in plasma and 55 metabolites in red blood cells (RBCs). Plasma from acute VTE patients expressed tendency to a specific metabolomic signature, with univariate analyses revealing 23 significantly different molecules between acute VTE patients and controls (p < 0.05). The most relevant metabolic pathway with the strongest impact on the acute VTE phenotype was D-glutamine and D-glutamate (p = 0.001, false discovery rate = 0.06). RBCs revealed a specific metabolomic signature in patients with a confirmed diagnosis of DVT or PE that distinguished them from other acutely diseased patients, represented by 20 significantly higher metabolites and four lower metabolites. Three of those metabolites revealed high performant ROC curves, including adenosine 3',5'-diphosphate (AUC 0.983), glutathione (AUC 0.923), and adenine (AUC 0.91). Overall, the metabolic pathway most impacting to the differences observed in the RBCs was the purine metabolism (p = 0.000354, false discovery rate = 0.68). CONCLUSIONS Our findings show that metabolite differences exist between acute VTE and nonacute VTE patients admitted to the ER in the early phases. Three potential biomarkers obtained from RBCs showed high performance for acute VTE diagnosis. Further studies should investigate accessible laboratory methods for the future daily practice usefulness of these metabolites for the early diagnosis of acute VTE in the ER.

Abstract
Extrusion-based 3D printing is steadily gaining importance as a manufacturing technique due to its flexibility and wide range of possible end-products. In the medical field, the technique is being exploited for a variety of applications and one of these is the production of personalised medicines. However, despite many proof-of-concept studies, more thorough insights in the production technique itself and the required material properties are needed before 3D printing can be fully exploited in a hospital or pharmacy setting. This research aims at clarifying the complex interplay between material properties, process parameters and printer-dependent variables. A variety of different polymers and polymer-drug blends were extruded (diameter 1.75±0.05 mm) and characterised in terms of mechanical, thermal and rheological properties. These properties, together with the processing temperature, printing speeds and different nozzle diameters of the 3D printer were linked to the quality of the end-product. Different failure mechanisms (mechanical, thermal) were assessed. Decisive material parameters (e.g. cross-over point) for optimal printing behaviour and the importance of printer construction (nozzle diameter) were clarified. In general, this study offers insight into the 3D printing process and will help to speed up future pharmaceutical formulation development for printlets.

Abstract
The estimation of the parameters of an odour source is of high relevance for multiple applications, but it can be a slow and error prone process. This work proposes a fast particle filter-based method for source term estimation with a mobile robot. Two strategies are implemented in order to reduce the computational cost of the filter and increase its accuracy: firstly, the sampling process is adapted by the mobile robot in order to optimise the quality of the data provided to the estimation process; secondly, the filter is initialised only after collecting preliminary data that allow limiting the solution space and use a shorter number of particles than it would be normally necessary. The method assumes a Gaussian plume model for odour dispersion. This models average odour concentrations, but the particle filter was proved adequate to fit instantaneous concentration measurements to that model, while the environment was being sampled. The method was validated in an obstacle free controlled wind tunnel and the validation results show its ability to quickly converge to accurate estimates of the plume’s parameters after a reduced number of plume crossings.

Abstract
Abstract
According to the Ministry of Justice and Public Security, Brazil is fourth in the world position in relation to the absolute size of female prison population, with 42.000 women deprived of freedom (2016), behind the United States, China and Russia. Around 50% are young (< 29 years old), 62% are black and 66% have not yet attended high school. This study aimed to characterize the profile of women incarcerated in a penitentiary in the interior of Brazil, through the survey of sociodemographic data, education, health, legal and life expectations. This is a descriptive and exploratory study conducted with 68 women (20 to 67 years old) in 2019 and 2020. Most women declared themselves black or brown (56%), incomplete elementary school (42%), have work experience (73%). Around 69% reported needing health treatment and 76% have already used psychoactive substances including alcohol, cigarettes, marijuana, cocaine or crack. The main reasons that led to the arrest were drug trafficking (54%) and theft (26%) and the majority (53%) are repeat offenders in prison system. Regarding the biggest dream of life, the main answers were related to family life (44%), having a job (26%) and access to education (20%). With these results, an extension project was proposed to offer a professional qualification in vegetable gardens, aromatic and medicinal plants for women prisoners. In addition to professional qualification, the project is dedicated to promoting debates on map of life, ethics, human relations, citizenship, gender, women's rights and health, quality of life, body and verbal expression, digital inclusion, food and nutrition security, entrepreneurship, cooperativism, solidary economy, rights and duties of the worker, aiming at better employment conditions. This research contributed to articulate actions between university and society, empower women through access to education and allowed the work team to develop competencies related to collaborative work and interdisciplinarity.

Abstract
HLA-G alleles follow a different pattern of polymorphism generation that those of the HLA classical I alleles. However, this polymorphism maintenance could have an evolutionary specific pathways based on non coding regions as introns, 14 bp deletion/insertion (exon 8) or promoter regions. For this reason, a systematic sequencing study of HLA-G promoter region was done in 36 individuals with a total of 15 different alleles. From the 12 sequences obtained, 7 were new sequences and not previously described. Results show that the sequences have three different patterns of evolution confirming the results obtained in the rest of the sequence regions (exons, introns and 3'UTR) where three different lineages were established. Only one of these lineages includes the non-human primate promoter sequences suggesting the possibility of this lineage could come directly from non-human primates while the other two could be generated after the speciation. More non-human primates MHC-G promoter sequences must be obtained to confirm this hypothesis. Expression and functional assays could be done considering the differences obtained in the promoter regions involving the HLA-G function (mRNA expression, isoforms).

Abstract
Human T lymphotropic virus type I(HTLV-I) has been implicated in various human diseases. Serum samples of 390 Brazilian Amazonians with cancer of various types were tested for HTLV-I antibodies by Gelatin particle agglutination test, Enzyme linked immunosorbent assay and Western blotting. Of 134 sera from patients with cancer of uterine cervix, 4 were positive by all the methods. Three of these were from non-transfused patients. DNA was extracted from 2 of 4 seropositive sera that gave strong reactions and were analyzed by PCR-SSCP for HTLV-I sequences. One was positive for all HTLV-I genes tested while the other one was positive for LTR and tax and negative for gag. In view of a possible pathway of the virus by sexual contact, the involvement of HTLV-I in cervical cancer warrants further studies.

Abstract
This paper presents the results from a serological survey developed in Mexico during 1987 in order to estimate the prevalence of anti Bordetella pertussis antibodies. Agglutinins were measured in 25,666 samples taken from children one to 15 years old living throughout the country. In each case survey covered some data about social and demographic variables such as socioeconomic stratum, number of DPT vaccine doses received and urban or rural settlement, among others. Titers greater than = 1.16 and 1.32 were considered positive; analysis is based on percent prevalence and geometric means of the antibody titers. We found a 65 per cent of total seropositivity, with higher prevalences in the northern and central states. Agglutinins response was higher among females subjects than in males. Children living in rural areas and those classified as belonging to lower socioeconomic level showed the lowest seropositivity prevalences.
