L1 transfer in the acquisition of manner and path in Spanish by native speakers of English
In this article the authors argue that L1 transfer from English is not only important in the early stages of L2 acquisition of Spanish, but remains influential in later stages if there is not enough positive evidence for the learners to progress in their development (Lefebvre, White, & Jourdan, 2006). The findings are based on analyses of path and manner of movement in stories told by British students of Spanish (N = 68) of three different proficiency levels. Verbs that conflate motion and path, on the one hand, are mastered early, possibly because the existence of Latinate path verbs, such as enter and ascend in English, facilitate their early acquisition by British learners of Spanish. Contrary to the findings of Cadierno (2004) and Cadierno and Ruiz (2006), the encoding of manner, in particular in boundary crossing contexts, seems to pose enormous difficulties, even among students who had been abroad on a placement in a Spanish-speaking country prior to the data collection. An analysis of the frequency of manner verbs in Spanish corpora shows that one of the key reasons why students struggle with manner is that manner verbs are so infrequent in Spanish. The authors claim that scarce positive evidence in the language exposed to and little or no negative evidence are responsible for the long-lasting effect of transfer on the expression of manner
Is hospital discharge administrative data an appropriate source of information for cancer registries purposes? Some insights from four Spanish registries
<p>Abstract</p> <p>Background</p> <p>The use of hospital discharge administrative data (HDAD) has been recommended for automating, improving, even substituting, population-based cancer registries. The frequency of false positive and false negative cases recommends local validation.</p> <p>Methods</p> <p>The aim of this study was to detect newly diagnosed, false positive and false negative cases of cancer from hospital discharge claims, using four Spanish population-based cancer registries as the gold standard. Prostate cancer was used as a case study.</p> <p>Results</p> <p>A total of 2286 incident cases of prostate cancer registered in 2000 were used for validation. In the most sensitive algorithm (that using five diagnostic codes), estimates for Sensitivity ranged from 14.5% (CI95% 10.3-19.6) to 45.7% (CI95% 41.4-50.1). In the most predictive algorithm (that using five diagnostic and five surgical codes) Positive Predictive Value estimates ranged from 55.9% (CI95% 42.4-68.8) to 74.3% (CI95% 67.0-80.6). The most frequent reason for false positive cases was the number of prevalent cases inadequately considered as newly diagnosed cancers, ranging from 61.1% to 82.3% of false positive cases. The most frequent reason for false negative cases was related to the number of cases not attended in hospital settings. In this case, figures ranged from 34.4% to 69.7% of false negative cases, in the most predictive algorithm.</p> <p>Conclusions</p> <p>HDAD might be a helpful tool for cancer registries to reach their goals. The findings suggest that, for automating cancer registries, algorithms combining diagnoses and procedures are the best option. However, for cancer surveillance purposes, in those cancers like prostate cancer in which care is not only hospital-based, combining inpatient and outpatient information will be required.</p
Cardiovascular risk estimated after 13 years of follow-up in a low-incidence Mediterranean region with high-prevalence of cardiovascular risk factors
<p>Abstract</p> <p>Background</p> <p>Murcia (south-east Spain) shows increased cardiovascular (CV) morbimortality as compared to other Spanish regions. Our objective was to assess the CV risk associated with major risk factors (RF) among adult population of Murcia.</p> <p>Methods</p> <p>A cohort of 2314 subjects (18-70 years) with full biochemical and questionnaire data was followed-up for 13 years. Incident cases of ischemic heart disease and stroke were identified by record linkage, individual questionnaires and revision of medical records. Relative risks were obtained by multivariate Cox regression stratified by age and sex, and ischemic risk attributable to CVRF was calculated.</p> <p>Results</p> <p>After more than 26276 person-years of follow-up, 57 incident ischemic events (77% men) and 37 stroke cases (62% men) were identified. Independent risk factors of ischemic heart disease (IHD) and all CV events combined, with RR ranging from 1.6 to 2.6, were total serum cholesterol ≥ 240 mg/dl (HR = 2.6, 95%CI:1.3-5.1), blood pressure levels ≥ 140/90 mmHg (HR = 2.6, 95%CI:1.4-4.8), ever tobacco smoking (HR = 2.2; 95%CI:1.1-4.5), and diabetes (HR = 2.0; 95%CI: 1.0-3.8). No increased CV risk was detected for known participants under treatment who showed cholesterol and blood pressure values below the clinical risk threshold. Smoking was significantly associated with stroke. For all events combined, the major risk factors were hypercholesterolemia, hypertension and ever use of tobacco. Despite its high prevalence, obesity was not associated to CV risk. Most of the IHD cases were attributable to smoking (44%), hypertension (38%) and hypercholesterolemia (26%).</p> <p>Conclusions</p> <p>In the Region of Murcia, smoking accounted for the largest proportion of cardiovascular risk, whereas hypertension displaced hypercholesterolemia as the second leading cause of CV disease. Our study deepens in our understanding of the cardiovascular epidemiology in Spanish areas of Mediterranean Europe with relatively high cardiovascular morbimortality, that are poorly represented by the available risk equations.</p
Risk of type 2 diabetes according to traditional and emerging anthropometric indices in Spain, a mediterranean country with high prevalence of obesity: results from a large-scale prospective cohort study
Background: Obesity is a major risk factor for type 2 diabetes mellitus (T2DM). A proper anthropometric
characterisation of T2DM risk is essential for disease prevention and clinical risk assessement.
Methods: Longitudinal study in 37 733 participants (63% women) of the Spanish EPIC (European Prospective
Investigation into Cancer and Nutrition) cohort without prevalent diabetes. Detailed questionnaire information was
collected at baseline and anthropometric data gathered following standard procedures. A total of 2513 verified
incident T2DM cases occurred after 12.1 years of mean follow-up. Multivariable Cox regression was used to
calculate hazard ratios of T2DM by levels of anthropometric variables.
Results: Overall and central obesity were independently associated with T2DM risk. BMI showed the strongest
association with T2DM in men whereas waist-related indices were stronger independent predictors in women.
Waist-to-height ratio revealed the largest area under the ROC curve in men and women, with optimal cut-offs at
0.60 and 0.58, respectively. The most discriminative waist circumference (WC) cut-off values were 99.4 cm in men
and 90.4 cm in women. Absolute risk of T2DM was higher in men than women for any combination of age, BMI
and WC categories, and remained low in normal-waist women. The population risk of T2DM attributable to obesity
was 17% in men and 31% in women.
Conclusions: Diabetes risk was associated with higher overall and central obesity indices even at normal BMI and
WC values. The measurement of waist circumference in the clinical setting is strongly recommended for the
evaluation of future T2DM risk in women
Early mobilisation in critically ill COVID-19 patients: a subanalysis of the ESICM-initiated UNITE-COVID observational study
Background
Early mobilisation (EM) is an intervention that may improve the outcome of critically ill patients. There is limited data on EM in COVID-19 patients and its use during the first pandemic wave.
Methods
This is a pre-planned subanalysis of the ESICM UNITE-COVID, an international multicenter observational study involving critically ill COVID-19 patients in the ICU between February 15th and May 15th, 2020. We analysed variables associated with the initiation of EM (within 72 h of ICU admission) and explored the impact of EM on mortality, ICU and hospital length of stay, as well as discharge location. Statistical analyses were done using (generalised) linear mixed-effect models and ANOVAs.
Results
Mobilisation data from 4190 patients from 280 ICUs in 45 countries were analysed. 1114 (26.6%) of these patients received mobilisation within 72 h after ICU admission; 3076 (73.4%) did not. In our analysis of factors associated with EM, mechanical ventilation at admission (OR 0.29; 95% CI 0.25, 0.35; p = 0.001), higher age (OR 0.99; 95% CI 0.98, 1.00; p ≤ 0.001), pre-existing asthma (OR 0.84; 95% CI 0.73, 0.98; p = 0.028), and pre-existing kidney disease (OR 0.84; 95% CI 0.71, 0.99; p = 0.036) were negatively associated with the initiation of EM. EM was associated with a higher chance of being discharged home (OR 1.31; 95% CI 1.08, 1.58; p = 0.007) but was not associated with length of stay in ICU (adj. difference 0.91 days; 95% CI − 0.47, 1.37, p = 0.34) and hospital (adj. difference 1.4 days; 95% CI − 0.62, 2.35, p = 0.24) or mortality (OR 0.88; 95% CI 0.7, 1.09, p = 0.24) when adjusted for covariates.
Conclusions
Our findings demonstrate that a quarter of COVID-19 patients received EM. There was no association found between EM in COVID-19 patients' ICU and hospital length of stay or mortality. However, EM in COVID-19 patients was associated with increased odds of being discharged home rather than to a care facility.

Meningomyelitis associated with infection by human herpes virus 7. Report of two cases Meningomielitis asociadas a infección por herpes virus humano 7. Comunicación de dos casos
Human herpesvirus 7 (HHV-7) may cause encephalomyelitis in immunocompetent adults. We report two patients infected by the virus. A 34-year-old male presenting with paraparesis and a sensitive deficiency located in D6 dermatome. Cerebrospinal fluid had 35 white blood cells per mm 3 and 75 mg protein per dl. A PCR-microarray examination was positive for HHV-7. The patient was treated with prednisolone and ganciclovir with full recovery. A 27-year-old male presenting with headache, fever and diarrhea. Cerebrospinal fluid analysis showed 160 cells per mm 3 and 75 mg protein per dl. Viral RNA detection was positive for HHV-7. The patient was managed with analgesia and rest and was discharged with the diagnosis of viral meningitis. Our comunication supports the notion that HHV-7 may be considered as pathogen factor in humans, even in immunocompetent ones
La gravedad de la infección por el virus respiratorio sincicial (VRS) y la participación del polimorfismo -2871 A>G del gen TLR-9 en lactantes chilenos menores de 6 meses de edad
Respiratory syncytial virus (RSV) is the most common cause of severe lower respiratory tract infection (LRTI) in infants. In Chile, 2% of children infected with RSV are hospitalized. Nowadays, genetic factors as Single Nucleotide Polymorphisms (SNPs) in innate immune
genes have been associated with the RSV infection severity. We studied the association between the SNP-2871 A>G (rs187084) in TLR9 gene and severity of infection in Chilean infants. Ninety seven, previously healthy term infants (< 6-months) with RSV-LRTI were analyzed. The severity of disease was determined by clinical scoring system. RSV and other respiratory virus were confirmed by immunofluorescence assays and, or reverse transcription-real time PCR in nasopharyngeal aspirate sample. SNP was analyzed by PCR
and RFLP in blood sample. Unphased program and Armitage’s test were used for genetic analysis. Infants were grouped in mild (n:31), moderate (n:28) and severe (n:38). There were no differences in sex or age between RSV groups. For all infants, the frequency for allele
A was 0.639. Genotypic frequencies were 40.2% A/A; 47.4% A/G and 12.4% G/G. There were not statistical differences between infant groups. The SNP -2871 A>G in TLR9 is not associated to severity RSV infection in Chilean infants
