Anolis lizards (anoles) are textbook study organisms in evolution and ecology. Although several topics in evolutionary biology have been elucidated by the study of anoles, progress in some areas has been hampered by limited phylogenetic information on this group. Here we present a phylogenetic analysis of all 379 extant species of Anolis, with new phylogenetic data for 139 species including new DNA data for 101 species. We use the resulting estimates as a basis for defining anole clade names under the principles of phylogenetic nomenclature and to examine the biogeographic history of anoles...

In a constantly changing world, animals must account for environmental volatility when making decisions. To appropriately discount older, irrelevant information, they need to learn the rate at which the environment changes. We develop an ideal observer model capable of inferring the present state of the environment along with its rate of change. Key to this computation is an update of the posterior probability of all possible change point counts. This computation can be challenging, as the number of possibilities grows rapidly with time...

The person-centered clinical method (PCCM) used in primary healthcare (PHC) is a useful tool to improve a person's approach to a health system that adequately responds to the needs of the population. PHC is built on the basis of a good health system, through compliance with its four attributes-first contact access, person focused care over time, comprehensiveness, and coordination of care-and it becomes an essential part of the growth of any nation that wants to provide quality healthcare. In conclusion, the PCCM is related to a strong PHC, as it is based on an approach focused on meeting people's needs...

If statesmanship can be characterized as a bed rock of principles, a strong moral compass, a vision, and an ability to articulate and effect that vision, then the fortitude, tenacity, imperturbability, and resilience of William Crawford Gorgas cannot be overestimated. As Chief Sanitary Officer in Cuba and as Chief Medical Officer in Panama, he actualized strategies to eradicate the vectors of yellow fever and malaria. His superiors initially pigeonholed his requisitions, refused to provide him with any authority, and clamored for his dismissal...

INTRODUCTION: In the context of the evaluation of hospital services, the incorporation of severity indices allows an essential control variable for performance comparisons in time and space through risk adjustment. The severity index for surgical services was developed in 1999 and validated as a general index for surgical services. Sixteen years later the hospital context is different in many ways and a revalidation was considered necessary to guarantee its current usefulness. OBJECTIVE: To evaluate the validity and reliability of the surgical services severity index to warrant its reasonable use under current conditions...

A long-standing question and dilemma in precision medicine is whether and to what extent genotyping or phenotyping drug metabolizing enzymes such as CYP2D6 can be used in real-life global clinical and societal settings. Although in an ideal world using both genotype and phenotype biomarkers are desirable, this is not always feasible for economic and practical reasons. Moreover, an additional barrier for clinical implementation of precision medicine is the lack of correlation between genotype and phenotype, considering that most of the current methods include only genotyping...

REVIEW
Danay Saavedra, Beatriz Garcia, Agustin Lage
The senescence of the immune system and the risk of cancer increase with aging. Age itself entails changes in the immune system, which are related to a decrease in thymic output of naïve lymphocytes, an accumulation of chronic antigenic load, notably chronic viral infections such as cytomegalovirus (CMV), and replicative senescence of lymphocytes. These changes could eventually contribute to cancer risk and affect the response to cancer treatment. However, several confounding factors make it difficult to draw a picture of causal relationships...

In 2015, a record-breaking 3.5 million visitors-1 million from Canada alone-traveled to Cuba to explore its history, culture, natural splendor, and visit family. That same year, US President Barack Obama relaxed travel restrictions, giving general authorization for a dozen categories of legal travel by US citizens and residents. As a result, US visitors to the island ballooned by 80% between January 2015 and June 2016. And the numbers keep growing: the latest data show that foreign arrivals reached 4 million in 2016...

There has been a notable decrease in the global practice of clinical autopsy; the rate has fallen to below 10%, even in high-income countries. This is attributed to several causes, including increased costs, overreliance on modern diagnostic techniques, cultural and religious factors, the emergence of new infectious diseases and negative attitudes on the part of doctors, even pathologists. Alternative methods to autopsy in postmortem studies have been developed based on imaging, endoscopy and biopsy (all quite expensive)...

INTRODUCTION Leprosy, an infectious disease caused by Mycobacterium leprae, affects the nervous system, skin, internal organs, extremities and mucous membranes. Biological, social and environmental factors influence its occurrence and transmission. The first effective treatments appeared in 1930 with the development of dapsone, a sulfone. The main components of a control and elimination strategy are early case detection and timely administration of multidrug therapy. OBJECTIVES Review the history of leprosy control in Cuba, emphasizing particularly results of the National Leprosy Control Program, its modifications and influence on leprosy control...

INTRODUCTION Systematic surveillance of antituberculosis drug resistance allows identification of multidrug-resistant and extensively drug-resistant isolates of Mycobacterium tuberculosis. Surveillance studies of antituberculosis drug resistance systematically conducted in Cuba for over 15 years have revealed low circulation of multidrug-resistant tuberculosis, under 1% in new cases. OBJECTIVE Characterize antituberculosis drug resistance in isolates of M. tuberculosis recovered from patients with pulmonary tuberculosis in Cuba in 2012-2014...

Nurse Sarait Guarat has Felipe's clinical history out of the file cabinet and on Dr Martha Diaz's desk before he's even through the door. Not that Dr Díaz needs it: Having served 26 years at Consultorio (Family Doctor-and-Nurse Office) #17 on a leafy street in Havana's Vedado neighborhood, she knows each of her patients by name and their health status essentially by heart. After greeting 91-year old Felipe with the customary kiss on the cheek, Dr Díaz gets down to business, asking after his family, checking up on his diabetes and inquiring about the reason for his visit...

Whether or not the so-called curse, "May you live in interesting times" is apocryphal, we have to acknowledge that we do indeed live in interesting times. It has been only three months since the October 2016 issue of MEDICC Review, but the changes since-in many directions-have been head-spinning. For starters, scientists at Roswell Park Cancer Institute have launched a clinical trial of CIMAvax, the therapeutic lung cancer vaccine developed at Cuba's Molecular Immunology Center, surely a win-win for the citizens of both countries...

Substantial progress in the application of multiple isotope analyses has greatly improved the ability to identify nonlocal individuals amongst archaeological populations over the past decades. More recently the development of large scale models of spatial isotopic variation (isoscapes) has contributed to improved geographic assignments of human and animal origins. Persistent challenges remain, however, in the accurate identification of individual geographic origins from skeletal isotope data in studies of human (and animal) migration and provenance...

Prorocentrum mexicanum and P. rhathymum are toxicologically important dinoflagellates, but their relationship is not well defined. We investigated strains from Puerto Rico and Brazil by light and scanning electron microscopies. We provide molecular data from a strain isolated near the type locality of P. rhathymum, and the first morphological and molecular data from the South Atlantic Ocean. The rRNA gene (rDNA) sequences of the Puerto Rican and Brazilian strains were identical, and their morphologies fit the description of P...
