The mammalian order Eulipotyphla includes four extant families of insectivorans: Solenodontidae (solenodons); Talpidae (moles); Soricidae (shrews); and Erinaceidae (hedgehogs). Of these, Solenodontidae includes only two extant species, which are endemic to the largest islands of the Greater Antilles: Cuba and Hispaniola. Most molecular studies suggest that eulipotyphlan families diverged from each other across several million years, with the basal split between Solenodontidae and other families occurring in the Late Cretaceous...

Vector-borne pathogens threaten human health worldwide. Despite their critical role in disease prevention, routine surveillance systems often rely on low-complexity pathogen detection tests of uncertain accuracy. In Chagas disease surveillance, optical microscopy (OM) is routinely used for detecting Trypanosoma cruzi in its vectors. Here, we use replicate T. cruzi detection data and hierarchical site-occupancy models to assess the reliability of OM-based T. cruzi surveillance while explicitly accounting for false-negative and false-positive results...

In 2016, 19.8% of the Cuban population was aged 60 or over. As a result, age-associated degenerative diseases and other diseases have become priority targets from a prophylactic, diagnostic and therapeutic perspective. As a result, the Cuban biomedical scientific community has addressed its basic, preclinical and epidemiological research in order to rise up to the challenge. A firm step in this direction has been the international congress "State of the art in non-clinical models for neurodegenerative diseases" which has brought together preclinical and clinical researchers, technicians and regulatory staff members from different countries to review the state of the art in neurodegenerations, find unifying ideas, objectives and collaborations or partnership...

Nevus lipomatosus cutaneus superficialis is a rare, hamartomatous disorder, characterized by the presence of ectopic mature adipose tissue within the superficial dermis. Lesions occur within the first three decades of life. We report four new cases, including a patient with the most extensive affectation reported to date, which was associated with massive lipomas in the subcutaneous cell tissue and diffuse lipomatosis. To our knowledge, it is the first report of this disorder in Cuba.

In 1936, Fulgencio Batista, the head of the Cuban military (and the de facto ruler of Cuba), founded the National Tuberculosis Council (CNT) to lead a state-directed anti-tuberculosis campaign. While most national and colonial governments neglected tuberculosis until the postwar period, populist politics pushed Batista to prioritize a disease of poverty by the mid-1930s. However, national politics also undermined efforts to control the disease in Cuba. Authoritarianism facilitated Batista's considerable influence over tuberculosis policy, and he and his advisors pursued political objectives rather than following the technical advice offered by professional groups...

The current conservation status of the bottlenose dolphin (Tursiops truncatus) under the IUCN is 'least concern'. However, in the Caribbean, small and localized populations of the 'inshore form' may be at higher risk of extinction than the 'worldwide distributed form' due to a combination of factors including small population size, high site fidelity, genetic isolation, and range overlap with human activities. Here, we study the population genetic structure of bottlenose dolphins from the Archipelago of Bocas del Toro in Panama...

A cross-sectional epidemiological study in the extreme-west of the state of Paraná was carried out to access the prevalence, distribution, and risk variables of canine Visceral Leishmaniases (cVL). This study was conducted in three areas, two cities of far west of Parana state: Foz do Iguaçu (FI) and Santa Terezinha de Itaipu (STI), and along two transects between these two municipalities. To sample the entire urban area, the cities (FI and STI) were divided into a grid of squares of 400 m2 (patch). Among the 526 patches, 123 in FI, 40 in the transects and 33 in STI were selected according to the 'worst scenario' criterion...

Annual trivalent influenza vaccines contain one of influenza B lineages; influenza B/Victoria-lineage or influenza B/Yamagata viruses. Theoretically, these vaccines should protect against viruses expected to circulate in the next influenza season. The National Influenza Centers, based on surveillance data from National Reference Laboratories, selects the strains composing each annual trivalent or tetravalent vaccine. Nevertheless, in some epidemics, vaccine strains do not match genetically with circulating strains...

Life is sustained by a variety of cyclic processes such as cell division, muscle contraction, and neuron firing. The periodic signals powering these processes often direct a variety of other downstream systems, which operate at different time scales and must have the capacity to divide or multiply the period of the master clock. Period modulation is also an important challenge in synthetic molecular systems, where slow and fast components may have to be coordinated simultaneously by a single oscillator whose frequency is often difficult to tune...
