Phylogenetic analyses showed that the virus responsible for a May 2024 Oropouche fever outbreak in Cuba was closely related to viruses from Brazil in 2023. Pools of Ceratopogonidae spp. biting midges and Culex quinquefasciatus mosquitoes were positive for Oropouche viral RNA.

Introduction: Genetic studies have shown associations of several single nucleotide polymorphisms (SNP) with different rates of progression and variation in susceptibility to HIV infection. This study aimed to estimate the frequency of ccr5Δ32, IL-6-174G/C, IFN-γ+874T/A and IL-10-1082A/G polymorphisms in Cuban HIV-infected patients and a group of sero-discordant couples to assess their influence on risk and disease progression.
Methods: A cross-sectional study was carried out on 120 subjects registered at the Institute of Tropical Medicine «Pedro Kour» (IPK) and the Ameijeiras Hospital from June 2018 until December 2019.
Background: The aim of this study is to report the radiological glenoid modifications and clinical outcomes at 3 years mean follow-up of hemi shoulder arthroplasty (HA) with pyrocarbon (PYC) humeral head. Our hypothesis was that the PYC implants would provide good outcomes without major glenoid erosion. Additionally, we hypothesized that HA-PYC allowed for remodeling of the bone.

- Arthroscopic surgery is the main treatment for rotator cuff calcific tendinopathy that doesn't respond to other treatments, but it can lead to a common complication called adhesive capsulitis in about 12% of cases.
- This study analyzed data from 340 patients to find risk factors for developing adhesive capsulitis, focusing on the impact of routine gleno-humeral exploration during surgery.
- Results showed that gleno-humeral exploration significantly increases the risk of adhesive capsulitis (odds ratio of 5.60), suggesting that this routine procedure may not be necessary and could be harmful.
Purpose: The aim of this study was to analyze the influence of several factors on the temperature in the work chamber during shoulder arthroscopy procedures in order to identify danger zones when using radiofrequency.
Methods: Intraarticular temperature was measured intraoperatively using system with special probe that directly measured the temperature in 22 patients. Data collection was prospective.
