Spatial and temporal variations of mercury (Hg) concentrations, enrichment, and potential ecological risks were studied in a suite of lead-210 (Pb) dated sediment cores from 13 Wider Caribbean Region coastal environments. Broad variability of Hg concentrations (19-18761 ng g) was observed, encompassing even background levels (38-100 ng g). Most Hg concentration profiles exhibited a characteristic upward trend, reaching their peak values in the past two decades.

However, the effect of apnea-hypopnea suppression on retinal disease progression is unclear. To evaluate the efficacy and safety of continuous positive airway pressure (CPAP) for the reduction of retinal lesions in patients with non-proliferative diabetic retinopathy (NPDR) and OSA.

Laboratory tests revealed lymphopenia, severe thrombocytopenia, and anicteric hepatitis. Her husband had been hospitalized three weeks earlier for a condition of similar characteristics without etiological diagnosis.

We have conducted a prospective multicenter study in CAT patients with more than 6 months of anticoagulant treatment to predict the risk of venous thromboembolism (VTE) recurrence after anticoagulation discontinuation. Blood samples were obtained when patients stopped the anticoagulation, at 21 days and at 90 days.

Some data suggest that several of these diseases may be associated with sleep-disordered breathing, mainly obstructive sleep apnea (OSA), due to intermediate mechanisms, such as intermittent hypoxia or sleep fragmentation. The aims of this systematic review were to identify and critically evaluate the current evidence supporting the existence of a possible relationship between OSA and the more relevant eye diseases as well as to evaluate the potential pathogenic mechanisms.

Yet, the relevance of major risk factors, including systolic blood pressure (SBP), diabetes, and body-mass index (BMI), to cardiovascular mortality in this population remains unclear.
Methods: In 1996-2002, 146,556 adults were recruited from the general population in five areas of Cuba.
Background: The average age at which people start smoking has been decreasing in many countries, but insufficient evidence exists on the adult hazards of having started smoking in childhood and, especially, in early childhood. We aimed to investigate the association between smoking habits (focusing on the age when smokers started) and cause-specific premature mortality in a cohort of adults in Cuba.
Methods: For this prospective study, adults were recruited from five provinces in Cuba.
Background: Most laboratory errors occur in the preanalytical phase. Among the most common preanalytical errors are interferences due to hemolysis, lipemia, and icterus. Our objective was to evaluate a serum interference estimation methodology by the RSD classifier, to identify other biochemical parameters affected by preanalytical interferences, and to determine the economic impact of its implementation.

The purpose of this study was to describe OCTA findings in several chorioretinal tumors, specifically melanocytic tumors. We correlate these findings with clinical risk factors (RFs) for growth.

Methods: We report a 41-year-old woman with 3 episodes of acute retinal pigment epitheliitis over a 3-year period. Spectral domain OCT and OCT angiography images were acquired with Cirrus 5,000 spectral domain OCT.
Background: The language encompassing health conditions can also influence behaviors that affect health outcomes. Few published quantitative studies have been conducted that evaluate HIV-related terminology changes over time. To expand this research, this study included an analysis of a dataset of abstracts presented at the International AIDS Conference (IAC) from 1989 to 2014.

Our objective was to determine the diagnostic yield of the UF-Series cytometer as a screening method for UTI.
Methods: All the urine samples sent to the six Microbiology Laboratories participating in a period of 5 working days were analyzed.
Unlabelled: The new Sysmex UF-1000i analyzer - which incorporates bacteria morphology distinction - allows to automatically screen samples to be cultured at microbiology laboratories. We have evaluated the feasibility and accuracy of Sysmex UF-1000i to screen urinary tract infections (UTIs). A total amount of 2468 urine samples from six Spanish hospitals were analysed.

This accounts for large amounts of valuable experimental data that may be readily exported into a standard and open format. Yet the publication of these data faces an important issue: Raw data are not made available; instead, the information is slimed down into a string of characters (the list of peaks).

Methods: Retrospective, noncomparative, consecutive evaluation by optical coherence tomography and its correlation with BCVA and CS in 31 eyes of 26 patients.
Results: In all affected patients, 88.
Our aim was to identify the potential risk factors for developing post-traumatic endophthalmitis (PTE) and the possible measures of prevention. Retrospective case-control study, with 15 cases of PTE and 2 matched controls. We reviewed the medical records of the cases and their respective controls during the period 1996-2008 at a Spanish Hospital.

We conducted a seroepidemiological survey to collect information on family background and the habits of people residing in Extremadura between 2002 and 2003. Antibodies to Brucella were determined by Rose Bengal staining and a standard tube agglutination test; a titer of 1/80 was considered to be positive.

Material And Methods: Retrospective study of patients with microbiological diagnosis of endophthalmitis treated at the Ophthalmology Department of the General Hospital La Mancha Centro in the period 1996-2008. The identification of isolates was performed using the automated VITEK-2® and Api galleries (bioMérieux, Spain SA).
A retrospective case-control study of patients who had undergone cataract extraction at a Spanish hospital over a 13-year period was conducted to identify the risk factors for developing post-operative endophthalmitis (POE). During the study period, the type of antibiotic prophylaxis was changed from subconjunctival gentamicin to the addition of both vancomycin and gentamicin to the irrigating solution. The overall incidence of POE was 0·19% (35 cases/18 287 operations).
View Article and Find Full Text PDFObjective: This study aims to assess whether changes in antibiotic prophylaxis used in cataract surgery in the La Mancha Centro General Hospital, Spain, were associated with a reduced incidence of postoperative endophthalmitis (POE).
Methods: The hospital employed two different antibiotic prophylaxis regimens during two clearly differentiated periods. In the first period (January 2000 to April 2003), subconjunctival injections of gentamicin were used while in the second (May 2003 to December 2008), vancomycin and gentamicin were added to the irrigating solution.
Introduction: During the last two decades an increased incidence of infections caused by multiresistant bacteria has been observed. The spread of these microorganisms in the hospital is a major therapeutic and epidemiological problem. The aim of this study was to determine local resistance patterns of microorganisms causative of multirresistant infections in patients admitted to our hospital.
