Spatial analysis for risk assessment of dengue in Spain.

INTRODUCTION: The establishment of Aedes albopictus in new areas in Europe has changed the risk of local dengue transmission represented by imported human cases. The risk of transmission is determined by the distribution of travelers arriving from dengue-endemic areas and the distribution of Ae. albopictus as potential vectors of dengue in Spain. METHODS: Environmental, entomological, epidemiological, demographic, tourism and travel data were analyzed to produce a series of maps to represent: the distribution of Ae. albopictus across municipalities; the risk of expansion of Ae. albopictus based on a species distribution model; the calculated index of travelers from dengue-endemic areas (IDVZE) per province; the percentage contribution of each municipality to the total number of cases in Spain. The maps were then added using map algebra, to profile the spatial risk of autochthonous dengue in Spain at a municipal level from 2016 to 2018. RESULTS: Ae. albopictus was detected in 983 municipalities. The calculated IDVZE varied from 0.23 to 10.38, with the highest IDVZE observed in Madrid. The overall risk of autochthonous cases oscillated between 0.234 and 115, with the very high risk and high risk areas detected in the Mediterranean region, mainly in the Levantine coast and some parts of the Balearic Islands. Most of the interior of the peninsula was characterized as low risk. CONCLUSION: Prevention and control measures to mitigate the risk of autochthonous dengue should be prioritized for municipalities in the high risk areas integrating early detection of imported dengue cases and vector control.

Intraobserver Repeatability Assessment of the S390L Firefly WDR Slitlamp in Patients With Dry Eye Disease: Objective, Automated, and Noninvasive Measures.

OBJECTIVES: To assess the intraobserver repeatability of automated, objective, and noninvasive measures obtained with the S390L Firefly WDR slitlamp. METHODS: This cross-sectional study included 50 eyes of patients with dry eye disease with a mean age of 55.06±12.96 years. Three consecutively repeated measures of the following variables were obtained: first noninvasive break-up time (F-NIBUT), average noninvasive break-up time (A-NIBUT), tear meniscus height, tear meniscus area (TMA), nasal ciliary hyperemia (NCIH), temporal ciliary hyperemia (TCIH), nasal conjunctival hyperemia (NCOH), temporal conjunctival hyperemia (TCOH), upper loss area meibomian gland (U-LAMG), lower loss area meibomian gland (L-LAMG), upper meibomian gland dysfunction grade (U-MGD grade), and lower meibomian gland dysfunction grade (L-MGD grade). Intraobserver repeatability was estimated with coefficient of variation (CoV), intrasubject standard deviation (SD) (S w ), and Bland-Altman plots. RESULTS: All variables showed no statistically significant differences in the repeated-measures analysis except for L-MGD grade ( P =0.045). F-NIBUT and A-NIBUT obtained the highest CoV with an average value of 0.48±0.41 [0.02-1.00] and 0.34±0.25 [0.02-1.00], respectively. The remaining variables showed CoVs between 0.04±0.11 [0.00-0.43] and 0.18±0.16 [0.00-0.75]. A-NIBUT, TMA, NCOH, and L-LAMG obtained an S w of 2.78s, 0.21 mm 2 , <0.001, and 4.11%, respectively. Bland-Altman plots showed a high level of agreement between pairs of repeated measures. CONCLUSION: The S390L Firefly WDR slitlamp has moderate intraobserver repeatability for F-NIBUT and A-NIBUT, which suggests that F-NIBUT and A-NIBUT are tests with high variability. The remaining variables show satisfactory intraobserver repeatability.

Choroidal thickness assessment in keratoconus patients treated with cross-linking compared to healthy population.

PURPOSE: To analyze the choroidal thickness between patients with keratoconus undergoing cross-linking treatment and a healthy population, as well as to determine the factors that influence choroidal thickness. METHODS: This was an observational, analytical, case-control study that was conducted from February 2021 to June 2021. Choroidal thickness was measured at different locations, including the subfoveal, nasal (1000 µm), temporal (1000 µm), superior (1000 µm) and inferior (1000 µm) locations using a Spectral-domain optical coherence tomography with enhanced depth imaging, which allowed us to obtain horizontal and vertical B-scans centered on the fovea. RESULTS: This study included 21 patients with keratoconus (mean age, 21.86 ± 5.28 years) and 28 healthy patients (mean age, 24.21 ± 4.71 years). Choroidal thickness was significantly greater in patients with keratoconus than in healthy patients in each of the following measured locations: subfoveal (P < 0.001); nasal (1000 µm) (P < 0.001), temporal (1000 µm) (P < 0.001), superior (1000 µm) (P < 0.001) and inferior (1000 µm) (P < 0.001) locations. Variables such as age (ρ = - 0.09; P = 0.50) and refraction (ρ = 0.14; P = 0.34) were not found to be associated with choroidal thickness. In a stepwise multiple linear regression, the group was the single variable correlated with choroidal thickness (ß = 0.88; P < 0.001). CONCLUSION: Choroidal thickness is thicker in keratoconus patients treated with cross-linking than in the healthy population. This finding could be associated with inflammatory choroidal mechanisms in keratoconus patients, but more studies are needed. Age and refractive error do not seem to influence choroidal thickness.

Emotion Classification from EEG with a Low-Cost BCI Versus a High-End Equipment.

The assessment of physiological signals such as the electroencephalography (EEG) has become a key point in the research area of emotion detection. This study compares the performance of two EEG devices, a low-cost brain-computer interface (BCI) (Emotiv EPOC+) and a high-end EEG (BrainVision), for the detection of four emotional conditions over 20 participants. For that purpose, signals were acquired with both devices under the same experimental procedure, and a comparison was made under three different scenarios, according to the number of channels selected and the sampling frequency of the signals analyzed. A total of 16 statistical, spectral and entropy features were extracted from the EEG recordings. A statistical analysis revealed a major number of statistically significant features for the high-end EEG than the BCI device under the three comparative scenarios. In addition, different machine learning algorithms were used for evaluating the classification performance of the features extracted from high-end EEG and low-cost BCI in each scenario. Artificial neural networks reported the best performance for both devices with an F[Formula: see text]-score of 75.08% for BCI and 98.78% for EEG. Although the professional EEG outcomes were higher than the low-cost BCI ones, both devices demonstrated a notable performance for the classification of the four emotional conditions.

Preliminary Assessment of Visible, Near-Infrared, and Short-Wavelength-Infrared Spectroscopy with a Portable Instrument for the Detection of Staphylococcus aureus Biofilms on Surfaces.

Bacterial biofilms constitute a major source of sanitary problems and economic losses in the food industry. Indeed, biofilm removal may require intense mechanical cleaning procedures or very high concentrations of disinfectants or both, which can be damaging to the environment and human health. This study assessed the efficacy of a technique based on spectroscopy in the visible, near-infrared, and short-wavelength infrared range for the quick detection of biofilms formed on polystyrene by the pathogenic bacterium Staphylococcus aureus. To do that, biofilms corresponding to three S. aureus strains, which differed in biofilm-forming ability and composition of the extracellular matrix, were allowed to develop for 5 or 24 h, representing an active formation stage and mature biofilms, respectively. Spectral analysis of the samples, corresponding to three biological replicates of each condition, was then performed by using a portable device. The results of these experiments showed that partial least-squares discriminant analysis of the spectral profile could discriminate between surfaces containing attached bacterial biomass and noninoculated ones. In this model, the two first principal components accounted for 39 and 19% of the variance and the estimated error rate stabilized after four components. Cross-validation accuracy of this assessment was 100%. This work lays the foundation for subsequent development of a spectroscopy-based protocol that allows biofilm detection on food industrial surfaces.

Se realizo un estudio de la mortalidad infantil durante nueve años en el cantón central de Cartago, Costa Rica. Objetivo: Determinar los factores asociados con la muerte infantil y compararlos con los encontrados en la literatura internacional. Metodología Se determino cuáles son los factores asociados a la muerte infantil comparando entre cada variable la categoría más deprivada socialmente con la menos deprivada para esto se comparó la tasa de expuestos contra la tasa de no expuestos, se estableció la diferencia de tasas, la razón de prevalencia y el valor p. Resultados: Las variables con mayor riesgo para la muerte infantil fueron; año de muerte, escolaridad de la madre, edad al morir, peso al nacer, condición socioeconómica de la madre, complicaciones en el embarazo, tipo de riesgo en el embarazo, actividad remunerada de la madre, calidad de la vivienda y escolaridad del padre. Discusión: Como resultado se validó la teoría de que la pobreza y las condiciones de desarrollo son los mayores predictores de muerte infantil.

Abstract Introduction: Child Mortality is correlated with poverty and a lower development of geographic communities. A study of child mortality was made over nine years in the central area of Cartago, Costa Rica. Objetive: To determine the factors associated with the infant death and compare them with those found in the international literature. Methodology: The factors related to child mortality were determined by comparing the more socially deprived category with the least in each variable. For this purpose the ¨exposed¨ rate was compared against the ¨not exposed¨, a difference between the rates was established, along with the prevalence ratio and the p value. Results: The variables with a bigger risk for child death were; Year of death, mother's level of study, age at time of death, weight at birth, mother's socioeconomic condition, complications during pregnancy, type of risk in the pregnancy, mother's paid activities, quality of housing and father's level of study. Discussion: As a result a theory was validated, which states that poverty and development conditions are the biggest predictors of child death.

Comparative analysis of different preservation techniques for the storage of Staphylococcus phages aimed for the industrial development of phage-based antimicrobial products.

Bacteriophages have been proven as effective antimicrobial agents in the treatment of infectious diseases and in other biocontrol applications including food preservation and disinfection. The extensive use of bacteriophages requires improved methodologies for medium- and long-term storage as well as for easy shipping. To this aim, we have determined the stability of four Staphylococcus phages (phiIPLA88, phiIPLA35, phiIPLA-RODI and phiIPLA-C1C) with antimicrobial potential at different temperatures (20°C/25°C, 4°C, -20°C, -80°C, -196°C) and during lyophilization (freeze drying) using several stabilizing additives (disaccharides, glycerol, sorbitol and skim milk). Differences between phages were observed at different temperatures (20°C/25°C, 4°C and -20°C), where phages were less stable. At lower temperatures (-80°C and -196°C), all phages showed good viability after 24 months regardless of the stabilizer. Differences between phages were also observed after lyophilization although the addition of skim milk yielded a dry powder with a stable titer after 24 months. As an alternative to facilitate storage and transportation, phage encapsulation has been also explored. Phage phiIPLA-RODI encapsulated in alginate capsules retained high viability when stored at 4°C for 6 months and at 20°C for 1 month. Moreover, the spray-dryer technique allowed obtaining dry powders containing viable encapsulated phages (phiIPLA-RODI and phiIPLA88) in both skim milk and trehalose for 12 months at 4°C. Storage of phages at 20°C was less effective; in fact, phiIPLA88 was stable for at least 12 months in trehalose but not in skim milk, while phiIPLA-RODI was stable only for 6 months in either stabilizer. These results suggest that encapsulated phages might be a suitable way for shipping phages.

Use of the Spanish Version of the Rapid Geriatric Assessment in Mexican Patients in Long-Term Care.

We report our experience with the use of a Spanish version of the rapid geriatric assessment of 30 patients in 2 long-term care institutions in Mexico City by a group of healthcare students without prior experience in geriatric medicine. The Spanish version of the rapid geriatric assessment is a very easy tool to administer that can provide overall good results for identifying frailty, sarcopenia, anorexia, weight loss, and cognitive impairment.

Real-Time Assessment of Staphylococcus aureus Biofilm Disruption by Phage-Derived Proteins.

A current focus of research is the development of new tools for removing bacterial biofilms in industrial settings. Bacteriophage-encoded proteins, such as endolysins, virion-associated peptidoglycan hydrolases, and exopolysaccharide depolymerases, have been shown to be efficient against these structures. However, the current screening techniques for the identification of antibiofilm properties of phage-derived proteins have important shortcomings. The aim of this work was to use the rapid, reproducible and accurate technology "real-time cell analyzer" for screening and comparing the antibiofilm ability of four phage-derived compounds, three lytic proteins (LysH5, CHAP-SH3b, and HydH5-SH3b) and one exopolysaccharide depolymerase (Dpo7) against Staphylococcus aureus biofilms, which have been associated with recurrent contamination of food products. The data generated after biofilm treatment allowed for the calculation of different antibiofilm parameters: (1) the minimum biofilm eradicating concentration that removes 50% of the biofilm (ranging from 3.5 ± 1.1 to 6.6 ± 0.5 µM), (2) the lowest concentration needed to observe an antibiofilm effect (∼1.5 µM for all the proteins), and (3) the specific antibiofilm activity and the percentage of biofilm removal that revealed LysH5 as the best antibiofilm compound. Overall, this technology might be used to quickly assess and compare by standardized parameters the disaggregating activity of phage antibiofilm proteins.

Relationship between mental health and spiritual wellbeing among hemodialysis patients: a correlation study.

CONTEXT AND OBJECTIVE: The stress of living with a terminal disease has a negative impact on the mental health of hemodialysis (HD) patients. Spirituality is a potential coping mechanism for stressful experiences. Studies on the relationship between spirituality and mental health among HD patients are scarce. The purpose of this study was to evaluate the relationship between mental health and spiritual well-being among HD patients. DESIGN AND SETTING: Cross-sectional observational study on hemodialysis patients at a single center in Brazil, between January and December 2011. METHODS: Mental health was assessed using the General Health Questionnaire and spiritual wellbeing was assessed using the Spiritual Wellbeing Scale; 150 HD patients participated in the study. RESULTS: A significant correlation was found between mental health and spiritual wellbeing (P = 0.001). Spiritual wellbeing was the strongest predictor of mental health, psychological distress, sleep disturbance and psychosomatic complaints. CONCLUSION: Poor mental health was associated with lower spiritual wellbeing. This has important implications for delivery of palliative care to HD patients.

Bem-estar espiritual foi o mais forte preditor de saúde mental, sofrimento psíquico, distúrbios do sono e queixas psicossomáticas. CONCLUSÃO: A saúde mental deficiente associou-se com menor bem-estar espiritual. Isso tem implicações importantes para a prestação de cuidados paliativos para pacientes em hemodiálise. .

Avaliação da complexidade da farmacoterapia em diabéticos / Assessment of medication regimen complexity among diabetics

Fundamentos: o diabetes mellitus (DM) é das principais causas de doença renal crônica (DRC). A hiperglicemia é dos fatores de risco para a DRC em diabéticos, muitas vezes ocasionada pela não adesão ao tratamento. A polifarmácia e a complexidade da farmacoterapia estão entre as principais causas de não adesão ao tratamento nesses pacientes. Objetivo: avaliar a complexidade da farmacoterapia em pacientes diabéticos. Métodos: estudo transversal e analítico realizado com 235 diabéticos tipo 2 que aceitaram participar da pesquisa e foram submetidos a dois instrumentos: questionário semiestruturado para levantamento de características socioeconômicas e clínicas e o Índice de Complexidade da Farmacoterapia (ICFT). Resultados: predominou indivíduos acima de 60 anos (60%); gênero feminino (65%); etnia branca (90%); tempo de estudo inferior a oito anos (88%); renda familiar abaixo de dois salários mínimos (72%); hipertensos (85%); obesos 68,5%); e com dislipidemia (64%). Os mais altos escores do ICFT correlacionaram-se com pior controle glicêmico (r= 0,16;p<0,01), mais longo tempo de diabetes (r=0,39;p<0,0001) e diminuição da função renal (r= - 0,19;p<0,004). Conclusão: o pior controle glicêmico sugere reduzida adesão dos pacientes ao tratamento, que poderia estar relacionada à maior complexidade da farmacoterapia e predispor à doença renal crônica.

Underpinnings: Diabetes mellitus (DMO) is one of the main causes of chronic kidney disease (CKD). Hyperglycemia is one of the risk factors for CKD among diabetics, often caused by noncompliance with treatment. Poly-drug use and medication regimen complexity are one of the major causes of noncompliance. Objective: To assess medication regimen complexity among diabetic patients. Methods: Analytic, cross-sectional study of 235 patients with type 2 diabetes that consented with the research involving two data collection tools: semi-structured questionnaire aimed at collecting their socio-economic and clinical data, and the Medication Regimen Complexity Index (MRCI). Results: The sample included predominantly patients that are at least 60 years old (60 %), women (65 %), white (90 %), hypertensive (85 %), and obese (68.5%), and have education level lower than 8 years (88 %), family income lower than two Brazilian minimum wages (72 %), and dyslipidemia (64 %). The highest MRCI scores correlate with worse glycemic control (r =0.16; p<0.01), longer time range of diabetes (r =0.39; p<0.0001), and reduced kidney function (r =0,19; p<0,004). Conclusion: The worst glycemic control suggests reduced compliance with treatment, which is probably associated with increased medication regimen complexity and predisposes patients to chronic kidney disease.

Self-perceived health status in older adults: regional and sociodemographic inequalities in Spain / Estado de saúde percebido em idosos: desigualdades regionais e sociodemográficas na Espanha / Estado de salud percibido en ancianos: disparidades regionales y sociodemográficas en España

OBJECTIVE: To assess regional and sociodemographic differences in self-perceived health status among older adults. METHODS: A face-to-face quality of life survey was conducted in a representative sample of the Spanish population comprising 1,106 non-institutionalized elderly aged 60 or more in 2008. Logistic regression models were used to explain self-perceived health status according to the EuroQol Group Visual Analogue Scale (EQ-VAS). Independent variables included sociodemographic and health characteristics as well as the nomenclature of territorial units for statistics level 1 (NUTS1: group of autonomous regions) and level 2 (NUTS 2: autonomous regions). RESULTS: Younger and better off respondents were more likely to have a positive self-perceived health status. Having no chronic conditions, independence in performing daily living activities and lower level of depression were also associated with positive self-perceived health status. People living in the south of Spain showed a more negative self-perceived health status than those living in other regions. CONCLUSION: The study results point to health inequality among Spanish older adults of lower socioeconomic condition and living in the south of Spain. The analysis by geographic units allows for international cross-regional comparisons.

OBJETIVO: Analisar as diferenças regionais e sociodemográficas no estado de saúde percebido por adultos mais velhos. MÉTODOS: Realizou-se um inquérito de qualidade de vida mediante entrevista pessoal com amostra representativa da população espanhola de 1.106 pessoas com 60 e mais anos não institucionalizadas, em 2008. Aplicaram-se modelos de regressão logística para explicar a saúde percebida segundo a escala visual analógica do EuroQol Group (EQ-VAS). As variáveis independentes incluíram características sociodemográficas e de saúde, assim como unidades territoriais estatísticas de nível 1 (grupo de comunidades autônomas) e nível 2 (comunidades autônomas). RESULTADOS: Os participantes dos grupos mais jovens e os que tinham uma melhor situação econômica mostraram maior probabilidade de ter uma percepção positiva da sua saúde. A ausência de problemas crônicos de saúde, a independência para realizar atividades da vida diária e menor nível de depressão também se associaram positivamente à saúde percebida como boa. Os idosos que viviam no sul mostraram uma percepção mais negativa da saúde do que as que vivem noutras regiões. CONCLUSÕES: Os resultados indicam uma desigualdade relativa no estado de saúde dos adultos mais velhos de níveis socioeconômicos inferiores e dos habitantes do sul do país. A análise por unidades territoriais estatísticas permite estabelecer comparações entre regiões em nível internacional.

Diagnostic accuracy, effectiveness and cost for cognitive impairment and dementia screening of three short cognitive tests applicable to illiterates.

BACKGROUND: Illiteracy, a universal problem, limits the utilization of the most widely used short cognitive tests. Our objective was to assess and compare the effectiveness and cost for cognitive impairment (CI) and dementia (DEM) screening of three short cognitive tests applicable to illiterates. METHODS: Phase III diagnostic test evaluation study was performed during one year in four Primary Care centers, prospectively including individuals with suspicion of CI or DEM. All underwent the Eurotest, Memory Alteration Test (M@T), and Phototest, applied in a balanced manner. Clinical, functional, and cognitive studies were independently performed in a blinded fashion in a Cognitive Behavioral Neurology Unit, and the gold standard diagnosis was established by consensus of expert neurologists on the basis of these results. Effectiveness of tests was assessed as the proportion of correct diagnoses (diagnostic accuracy [DA]) and the kappa index of concordance (k) with respect to gold standard diagnoses. Costs were based on public prices at the time and hospital accounts. RESULTS: The study included 139 individuals: 47 with DEM, 36 with CI, and 56 without CI. No significant differences in effectiveness were found among the tests. For DEM screening: Eurotest (k = 0.71 [0.59-0.83], DA = 0.87 [0.80-0.92]), M@T (k = 0.72 [0.60-0.84], DA = 0.87 [0.80-0.92]), Phototest (k = 0.70 [0.57-0.82], DA = 0.86 [0.79-0.91]). For CI screening: Eurotest (k = 0.67 [0.55-0.79]; DA = 0.83 [0.76-0.89]), M@T (k = 0.52 [0.37-0.67]; DA = 0.80 [0.72-0.86]), Phototest (k = 0.59 [0.46-0.72]; DA = 0.79 [0.71-0.86]). There were no differences in the cost of DEM screening, but the cost of CI screening was significantly higher with M@T (330.7 ± 177.1 €, mean ± sd) than with Eurotest (294.1 ± 195.0 €) or Phototest (296.0 ± 196. 5 €). Application time was shorter with Phototest (2.8 ± 0.8 min) than with Eurotest (7.1 ± 1.8 min) or M@T (6.8 ± 2.2 min). CONCLUSIONS: Eurotest, M@T, and Phototest are equally effective. Eurotest and Phototest are both less expensive options but Phototest is the most efficient, requiring the shortest application time.

Effectiveness and costs of phototest in dementia and cognitive impairment screening.

BACKGROUND: To assess and compare the effectiveness and costs of Phototest, Mini Mental State Examination (MMSE), and Memory Impairment Screen (MIS) to screen for dementia (DEM) and cognitive impairment (CI). METHODS: A phase III study was conducted over one year in consecutive patients with suspicion of CI or DEM at four Primary Care (PC) centers. After undergoing all screening tests at the PC center, participants were extensively evaluated by researchers blinded to screening test results in a Cognitive-Behavioral Neurology Unit (CBNU). The gold standard diagnosis was established by consensus of expert neurologists. Effectiveness was assessed by the proportion of correct diagnoses (diagnostic accuracy [DA]) and by the kappa index of concordance between test results and gold standard diagnoses. Costs were based on public prices and hospital accounts. RESULTS: The study included 140 subjects (48 with DEM, 37 with CI without DEM, and 55 without CI). The MIS could not be applied to 23 illiterate subjects (16.4%). For DEM, the maximum effectiveness of the MMSE was obtained with different cutoff points as a function of educational level [k = 0.31 (95% Confidence interval [95%CI], 0.19-0.43), DA = 0.60 (95%CI, 0.52-0.68)], and that of the MIS with a cutoff of 3/4 [k = 0.63 (95%CI, 0.48-0.78), DA = 0.83 (95%CI, 0.80-0.92)]. Effectiveness of the Phototest [k = 0.71 (95%CI, 0.59-0.83), DA = 0.87 (95%CI, 0.80-0.92)] was similar to that of the MIS and higher than that of the MMSE. Costs were higher with MMSE (275.9 ± 193.3€ [mean ± sd euros]) than with Phototest (208.2 ± 196.8€) or MIS (201.3 ± 193.4€), whose costs did not significantly differ. For CI, the effectiveness did not significantly differ between MIS [k = 0.59 (95%CI, 0.45-0.74), DA = 0.79 (95%CI, 0.64-0.97)] and Phototest [k = 0.58 (95%CI, 0.45-0.74), DA = 0.78 (95%CI, 0.64-0.95)] and was lowest for the MMSE [k = 0.27 (95%CI, 0.09-0.45), DA = 0.69 (95%CI, 0.56-0.84)]. Costs were higher for MMSE (393.4 ± 121.8€) than for Phototest (287.0 ± 197.4€) or MIS (300.1 ± 165.6€), whose costs did not significantly differ. CONCLUSION: MMSE is not an effective instrument in our setting. For both DEM and CI, the Phototest and MIS are more effective and less costly, with no difference between them. However, MIS could not be applied to the appreciable percentage of our population who were illiterate.
