The aim of this study was to evaluate the level of knowledge on oral cancer and level of preventive care among the population. A descriptive cross-sectional study was performed to evaluate 408 individuals through a face-to-face survey at Universidad Católica de Santiago de Guayaquil during the 2016 academic year. Sixty-one percent (61%) of respondents said they knew of the existence of oral cancer, but 56.1% did not know that 'white spots' in the oral cavity could become malignant, and 50.7% did not know that 'lumps'could be oral cancer...

The common bottlenose dolphin, Tursiops truncatus , is widely distributed along the western coast of South America. In Ecuador, a resident population of bottlenose dolphins inhabits the inner estuarine area of the Gulf of Guayaquil located in the southwestern part of the country and is under threat from different human activities in the area. Only one genetic study on South American common bottlenose dolphins has been carried out to date, and understanding genetic variation of wildlife populations, especially species that are identified as threatened, is crucial for defining conservation units and developing appropriate conservation strategies...

Dengue fever, a mosquito-borne arbovirus, is a major public health concern in Ecuador. In this study, we aimed to describe the spatial distribution of dengue risk and identify local social-ecological factors associated with an outbreak of dengue fever in the city of Guayaquil, Ecuador. We examined georeferenced dengue cases ( n = 4248) and block-level census data variables to identify social-ecological risk factors associated with the presence/absence and burden of dengue in Guayaquil in 2012. Local Indicators of Spatial Association (LISA), specifically Anselin’s Local Moran’s I, and Moran’s I tests were used to locate hotspots of dengue transmission, and multimodel selection was used to identify covariates associated with dengue presence and burden at the census block level...

Escherichia coli is one of the major causes of urinary tract infections in primary healthcare, and treatment is more complicated due to the increase in antibiotic resistance. Extended-spectrum β-lactamases are the most common mechanism of resistance against third-generation cephalosporin, and CTX-M-like are among the most prevalent. The aim of our work is to investigate the prevalence of blaCTX-M in isolates of E. coli obtained from samples of patients without previous known contact with the hospital. Ninety-four E...

Aedes (Stegomyia) albopictus (Skuse), (Diptera: Culicidae), the Asian tiger mosquito, is one of the most widespread invasive vector-borne disease insect in tropical and temperate zones. This species has invaded the Americas over the past 3 decades and has spread to six countries. We report Ae. albopictus in Guayaquil city, the first time it has been identified in Ecuador. Outdoor BG-Sentinel traps without lures collected a total of 21 Ae. albopictus.

BACKGROUND: This study aimed to characterize which are the early determinants of immediate failure of the use of noninvasive mechanical ventilation (NIMV) outside the ICU. METHODS: This prospective study included patients who were admitted to the Military Hospital in Guayaquil, Ecuador. Each variable was analyzed independently by using a multiple logistic regression model toward establishing an association with the event. RESULTS: A total of 249 cases of NIMV over a 10 year period of its application outside the ICU was included in the study...

INTRODUCTION: Neurocryptococcosis is an opportunistic fungal infection that represents a high cost in human lives and for the economy of countries. Its causative agent, the Cryptococcus neoformans/Cryptococcus gattii species complex, has a sexual and an asexual phase, four major serotypes and seven molecular varieties with phenotypic, clinical-epidemiological and antifungal susceptibility differences. OBJECTIVE: To characterize by molecular methods clinical isolates of C...

Three propolis samples were collected from different regions of Ecuador (Quito, Guayaquil and Cotacachi) and their methanolic extracts were prepared. Preliminary information supplied by TLC and NMR data, allowed us to define two main types of propolis: Cotacachi propoli sample (CPS), rich in flavonoids and Quito and Guayaquil samples (QPS and GPS) containing triterpenic alcohols and acetyl triterpenes as the main constituents. Two different approaches based on RP-HPLC preparative procedure and NMR structural determination (CPS) and GC-MS analysis (QPS and GPS) were successfully used for the chemical characterization of their major compounds...

The thermal environment outdoors affects human comfort and health. Mental and physical performance is reduced at high levels of air temperature being a problem especially in tropical climates. This paper deals with human comfort in the warm-humid city of Guayaquil, Ecuador. The main aim was to examine the influence of urban micrometeorological conditions on people's subjective thermal perception and to compare it with two thermal comfort indices: the physiologically equivalent temperature (PET) and the standard effective temperature (SET*)...

Zika virus (ZIKV) infection during pregnancy has been linked to severe birth defects, and the epidemiologic situation of the ZIKV epidemic in Ecuador is poorly understood. Guayaquil, Ecuador, has a tropical climate and experiences frequent outbreaks of dengue and chikungunya virus, and in December 2015, ZIKV was identified. Given the well-documented effects of ZIKV in pregnancy, including microcephaly, we tested for the presence of ZIKV in both plasma and cervical cytology of pregnant women. We report the identification of a population of pregnant women with a high incidence of ZIKV infection detected in the plasma and lower reproductive tract...

Zika virus (ZIKV), chikungunya virus (CHIKV), and dengue virus (DENV) have been associated with clinical presentations that involve acute neurological complaints. In the current study, we identified ZIKV, CHIKV, and DENV in cerebrospinal fluid (CSF) samples from patients admitted to the Hospital Luis Vernaza (Guayaquil, Ecuador) to the Emergency Room or the Intensive Care Unit, with neurological symptoms and/or concern for acute arboviral infections. Viral RNA from one or more virus was detected in 12/16 patients...

We report a Serratia marcescens outbreak occurred in the NICU of a pediatric hospital in Guayaquil, Ecuador. Nine cases of infection were detected, from which septicemia was developed in 55.5%. The index case was a newborn derived from another institution with septic arthritis caused by the outbreak strain. The infection rate was 17.6% and mortality rate was 33.3%. All isolates were resistant to aminoglycosides and susceptible to third generation cephalosporins and carbapenems. Clonality analysis by pulsed-field gel electrophoresis (PFGE) revealed the presence of two closely related clones confirming the horizontal spread...

BACKGROUND: Metabolic syndrome increases cardiovascular risk, and causes damage to the vascular wall. Through this mechanism, it might increase arterial rigidity, leading to further complications and heart strain. The use of a device that measures arterial rigidity can help determine if metabolic syndrome is related to a higher vascular stiffness and changes in estimated arterial age. METHODOLOGY: Cross-sectional study at Luis Vernaza hospital of Guayaquil, Ecuador...
