Determinants of HIV-1 Transmission Clusters and Transmitted Drug Resistance in ...
Abrantes, Ricardo; Pimentel, Victor; Sebastião, Cruz; Miranda, Mafalda N S; Seabra, Sofia; Silva, Ana Rita; Diniz, António; Ascenção, BiancaIntroduction: In the EU/EEA, men who have sex with men (MSM) is a priority group for the prevention and control of HIV-1 infection. In Portugal, the 2023 HIV incidence rate was 8.2 per 100,000 inhabitants, with 876 new infections, 41.7% in MSM. We aim to characterize HIV-1 transmission clusters (TC) and transmitted drug resistance (TDR) and its sociodemographic, behavioral, clinical, and viral genomic determina...

Preliminary findings from the follow-up of pregnant sickle cell disease patient...
Brito, Miguel; Ginete, Catarina; Ferreira, J.; Delgadinho, Mariana; Sebastião, Cruz; Mateus, A.; Mendes, M.; Quinto, F.; Simão, F.; Fernandes, F.Background: In Angola, the prevalence of Sickle Cell Disease (SCD) is almost 2%, and the carriers reach 21% of the population. Although its presentation tends to be very heterogeneous, chronic hemolytic anemia, frequent painful crises, and extensive organ damage are common features of these patients. Pregnancy in SCD patients is associated with an increase in severe outcomes, namely, a high risk of eclampsia an...

Arrais, Margarete; Dias, Welwitschia; Silva, Maura; Neto, Luquenia; Pedro, Naiol; Jungo, Sónia; Miguel, Avelina; Fortes-Gabriel, Elsa; Sebastião, CruzBackground: The impact of SARS-CoV-2 infection in Africa is still unclear. In comparison to Europe and North America, morbidity and death rates are lower. Several factors have been proposed, including geographical variation in virus impact, environmental factors, differences in age distribution, and the impact of infectious diseases such as malaria, HIV infection, and tuberculosis. Objectives: We investigated t...
Pregnancy surveillance in sickle cell disease patients: a cohort study in an Af...
Brito, Miguel; Ginete, Catarina; Ferreira, Joana; Mendes, Manuela; Vasconcelos, Jocelyne; Delgadinho, Mariana; Sebastião, Cruz; Quinto, FranciscoSickle Cell Disease (SCD) is a severe monogenic disease caused by the inherence of a recessive mutation in the β-globin gene, with an especially high prevalence in sub-Saharan Africa. In Angola, the prevalence of the disease is almost 2%, and the carriers reach 21% of the population. Although its presentation tends to be very heterogeneous, chronic hemolytic anemia, frequent painful crises, and extensive organ ...
Genetic variability and disease severity in a cohort of Angolan sickle cell dis...
Brito, Miguel; Ferreira, J.; Capriello, I.; Ginete, Catarina; Delgadinho, Mariana; Sebastião, Cruz; Mendes, M.; Quinto, F.; Mavunza, F.; Vasconcelos, J.Purpose: Sickle Cell Anaemia (SCA) is an inherited autosomal and lethal blood disorder caused by a mutation in the HBB gene that promotes haemoglobin (Hb) polymerization and consequent sickling of red blood cells (RBCs) in hypoxia. Regardless of being a monogenic disease, SCA has a remarkably high clinical heterogeneity in its phenotypic expression. Several factors have been shown to modulate the clinical manif...
