RESUMO

BACKGROUND: The aim of this research is to evaluate the periodontal health of patients with Parkinson Disease (PD) in a Spanish cohort. MATERIAL AND METHODS: A cross-sectional study was performed on 104 patients with PD (mean age: 66.19+9.3 years) and 106 controls (mean age: 59.26+14.11 years). A pre-designed clinical protocol was implemented, which included a standardized epidemiological index for periodontal disease (CPITN), clinical attachment loss (CAL), tooth-loss, full mouth plaque index (FMPI), and oral hygienic habits. Univariate descriptions and comparative analysis were performed. RESULTS: The majority of PD patients presented good oral hygienic habits. There were no significant differences in relation to CPITN, periodontitis, gingival recessions and tooth loss. However, moderate/severe CAL (p=0.027) and FMPI (p=0.003) was higher in the PD group. CONCLUSIONS: There were no differences on periodontitis and tooth loss between both groups. The higher number of advanced CAL and presence of biofilm in the PD group could be related to the difficulties to perform an effective tooth brushing due to this neurological disorder.

RESUMO

BACKGROUND: Parkinson's disease (PD) is one of the leading neurological disorders, affecting more than 6 million people worldwide. These patients present motor and non-motor symptoms, including oral pathology. The objective of this research is to determine the oral health of patients diagnosed with PD, in order to stablish a specific preventive oral health programme. MATERIAL AND METHODS: Case-control study on 104 PD and 106 control patients. The pre-designed clinical protocol included a complete oral examination on general aspects, standardised epidemiological index for caries, periodontal disease and edentulism, analysis of oral hygiene, presence of mucous/ salivary/ functional disorder, and dental treatments. RESULTS: A higher number of PD patients consumed daily sweets (p<0.004) and antidepressant drugs (p<0.004). Patients with PD practised less interdental hygiene (p<0.023). The mean plaque index was higher in PD (p<0.003). Drooling (p<0.001), xerostomia (p<0.001), hyposialia (p<0.001), dysphagia (p<0.001), hypogeusia/dysgeusia (p<0.025) and chewing difficulty (p<0.006) were more common in PD. CONCLUSIONS: Oral disorders are frequent in PD. A good knowledge of these alterations will allow us design a specific preventive protocol. Some oral alterations may be a sign of diagnostic alert or progression of PD.

RESUMO

The synthesis and characterization of a series of closely related Y(III) compounds comprising the formamidinate ligands (RNCHNR) (R = alkyl) is reported, with the scope of using them as prospective precursors for atomic layer deposition (ALD) of yttrium oxide (Y2O3) thin films. The influence of the side chain variation on the thermal properties of the resulting complexes is studied and benchmarked by thermal analysis and vapor pressure measurements. Density functional theory (DFT) studies give theoretical insights into the reactivity of the compounds towards water, which was targeted as a co-reactant for the deposition of Y2O3via thermal ALD in the next step. Among the four complexes analyzed, tris(N,N'-di-tert-butyl-formamidinato)yttrium(III) [Y(tBu2-famd)3] 1 was found to possess enhanced thermal stability and was selected for Y2O3 ALD process development. A broad ALD window ranging from 200 °C to 325 °C was obtained, yielding films of high compositional quality. Furthermore, with a film density of (4.95 ± 0.05) g cm-1 close to the bulk value, polycrystalline fcc Y2O3 layers with a smooth topography resulted in promising dielectric properties when implemented in metal insulator semiconductor (MIS) capacitor structures.

RESUMO

We report the application of tris(N,N'-diisopropyl-formamidinato)yttrium(iii) [Y(DPfAMD)3] as a promising precursor in a water-assisted thermal atomic layer deposition (ALD) process for the fabrication of high quality Y2O3 thin films in a wide temperature range of 150 °C to 325 °C. This precursor exhibits distinct advantages such as improved chemical and thermal stability over the existing Y2O3 ALD precursors including the homoleptic and closely related yttrium tris-amidinate [Y(DPAMD)3] and tris-guanidinate [Y(DPDMG)3], leading to excellent thin film characteristics. Smooth, homogeneous, and polycrystalline (fcc) Y2O3 thin films were deposited at 300 °C with a growth rate of 1.36 Å per cycle. At this temperature, contamination levels of C and N were under the detectable limits of nuclear reaction analysis (NRA), while X-ray photoelectron spectroscopy (XPS) measurements confirmed the high purity and stoichiometry of the thin films. From the electrical characterization of metal-insulator-semiconductor (MIS) devices, a permittivity of 13.9 at 1 MHz could be obtained, while the electric breakdown field is in the range of 4.2 and 6.1 MV cm-1. Furthermore, an interface trap density of 1.25 × 1011 cm-2 and low leakage current density around 10-7 A cm-2 at 2 MV cm-1 are determined, which satisfies the requirements of gate oxides for complementary metal-oxide-semiconductor (CMOS) based applications.

RESUMO

The Latin American population has a double way of immigration, one toward the United States by proximity and another toward Spain by sociocultural affinity. This population increase is affecting organ donation and transplantation in receiving countries. OBJECTIVE: To analyze the brain death (BD) concept knowledge in the Dominican Republic immigrant population in Florida (United States) and Spain. METHOD: Population under study: Population born in the Dominican Republic, resident in Florida (United States) and in Spain. INCLUSION CRITERIA: Population older than 15 years stratified by age and sex. Assessment instrument: Donation attitude questionnaire PCID-DTO-Ríos. Fieldwork: Random selection based on stratification. Immigration support association collaboration in Florida and Spain was needed to locate potential respondents. Completion was anonymous and self-administered, with verbal consent. RESULTS: A total of 123 respondents, 57 residents in Spain and 66 in Florida, have been included in the study. The 27% (n = 33) of the respondents knowledgeable of the BD concept consider it the death of an individual. Of the remainder, 52% (n = 64) do not know about it, and the remaining 21% (n = 26) believe it does not mean the death of a patient. No differences were observed regarding migration countries (P > .05). There was no association of the BD concept with other psychosocial factors analyzed or with the attitude toward organ donation. CONCLUSIONS: Knowledge of the BD concept among the Dominican immigrant population is similar in Spain and Florida, and, unlike most studies, there is no objective association with the attitude toward organ donation.

RESUMO

Neodymium sulphide (Nd2S3) belongs to the exciting class of rare earth sulphides (RES) and is projected to have a serious potential in a wide spectrum of application either in pure form or as dopant. We demonstrate a facile and first growth of Nd2S3 thin films via metal-organic chemical vapour deposition (MOCVD) at moderate process conditions using two new Nd precursors, namely tris(N,N'-diisopropyl-2-dimethylamido-guanidinato)Nd(iii) and tris(N,N'-diisopropyl-acetamidinato)Nd(iii). The promising thermal properties and suitable reactivity of both Nd precursors towards elemental sulphur enabled the formation of high purity γ-Nd2S3. While the process temperature for film growth ranged from 400 °C to 600 °C, the films were crystalline above 500 °C. We also demonstrate that the as-deposited γ-Nd2S3 are luminescent, with the optical bandgap ranging from 2.3 eV to 2.5 eV. The process circumvents post-deposition treatments such as sulfurisation to fabricate the desired Nd2S3, which paves the way for large scale synthesis and also opens up new avenues for exploring the potential of this class of materials with properties for functional applications.

RESUMO

INTRODUCTION: Immigrants from Ecuador represent the largest group of Latin Americans in Spain and are, therefore, a subgroup of interest to understand their attitudes and influences in respect to organ donation and transplantation. OBJECTIVE: To analyze the attitude of nationals of Ecuador residing in Spain regarding deceased organ donation. METHODS: The study population included the Ecuadorian population residing in Spain. A sample of population older than 15 years was obtained randomly and stratified by age and sex (n=461). Attitude was assessed using a validated questionnaire on psychosocial aspects toward organ donation (PCID-DTO-Ríos). Assistance from immigration support associations in Spain was needed to advice on the location of potential respondents. RESULTS: Attitude toward cadaveric donation was favorable in 59% (n=271) of respondents, 12% (n=57) were against cadaveric donation, and 29% (n=133) were undecided. Several variables were associated with having a more favorable attitude. In the multivariate analysis, the following variables were independently associated with a more positive attitude toward organ donation: 1. level of formal education (odds ratio [OR]=6.849 [25.641-1.818]; P = .004); 2. being in favor of donating a family member's organs (OR=8.849 [20.833-3.717]; P < .001); 3. having commented at a family level about transplant (OR=3.717 [6.578-2.109]; P < .001); 4. not being concerned about the possible mutilation of the body after donation (OR=4.608 [8.547-2.487]; P < .001) and 5. knowing the attitude of one's religion toward donation (OR=7.462 [34.482-1.623]; P = .010). CONCLUSIONS: The attitude toward cadaveric organ donation among the Ecuadorian population residing in Spain is less favorable than that of the Spanish population and is determined by many different psychosocial variables.

RESUMO

INTRODUCTION: The Bolivian population is growing in Spain. The knowledge and acceptance of the concept of brain death are fundamental. OBJECTIVE: To analyze the level of understanding of the brain death concept among the population of Bolivians residing in Spain. METHODS: The study population was Bolivians living in Spain. The inclusion criteria were being older than 15 years, being born in Bolivia, and residing in Spain; participants were selected randomly from this group and stratified by age and sex. Knowledge of the concept of brain death was assessed using a validated questionnaire on psychosocial aspects toward organ donation. A group of people to be surveyed was randomly selected. Assistance from immigration support associations in Spain was needed to advise on the location of potential respondents. The survey was self-administered and completed anonymously. RESULTS: Of the 206 respondents, 27% understood brain death (BD) and believed that this was the death of an individual. Of the rest, 18% did not understand it and the remaining 55% believed it did not mean the death of a patient. Those who understood the concept of BD were more in favor of deceased donation than those who did not (52% vs 47%; P = .886). None of the sociopersonal variables analyzed is associated with knowledge of the concept of BD. A high percentage of respondents indicated fear of apparent death during organ donation. CONCLUSIONS: The majority of the Bolivian population residing in Spain does not understand the concept of BD. Contrary to most psychosocial studies, it is not associated with attitudes toward organ donation or other sociopersonal factors.

RESUMO

Friedreich's ataxia (FRDA) is a rare inherited recessive disorder affecting the central and peripheral nervous systems and other extraneural organs such as the heart and pancreas. This incapacitating condition usually manifests in childhood or adolescence, exhibits an irreversible progression that confines the patient to a wheelchair, and leads to early death. FRDA is caused by a reduced level of the nuclear-encoded mitochondrial protein frataxin due to an abnormal GAA triplet repeat expansion in the first intron of the human FXN gene. FXN is evolutionarily conserved, with orthologs in essentially all eukaryotes and some prokaryotes, leading to the development of experimental models of this disease in different organisms. These FRDA models have contributed substantially to our current knowledge of frataxin function and the pathogenesis of the disease, as well as to explorations of suitable treatments. Drosophila melanogaster, an organism that is easy to manipulate genetically, has also become important in FRDA research. This review describes the substantial contribution of Drosophila to FRDA research since the characterization of the fly frataxin ortholog more than 15 years ago. Fly models have provided a comprehensive characterization of the defects associated with frataxin deficiency and have revealed genetic modifiers of disease phenotypes. In addition, these models are now being used in the search for potential therapeutic compounds for the treatment of this severe and still incurable disease.

RESUMO

BACKGROUND: The Puerto Rican population represents one of the largest immigration groups in Florida, and this has an impact on the organ transplant donation process. Our aim was to analyze attitudes toward organ donation among Puerto Ricans who currently reside in the state of Florida (USA). METHODS: The population screened consisted of individuals >15 years old, who were born in Puerto Rico, living in Florida, and awaiting organs for transplant. All participants completed the "PCID-DTO Rios" questionnaire. Random selection was done according to stratification. Support from immigration associations in Spain was needed for advice on the locations of potential respondents. Study participation was anonymized and self-administered. RESULTS: There were 259 respondents, 37% (n = 95) were in favor of donation, 36% (n = 93) were against donation, and 27% (n = 71) were undecided. The variables associated with these attitudes were: age (P = .017); civil status (P = .021); level of education (P < .001); previous experience with donation and transplant (P < .001); attitude toward organ donation of a relative (P < .001); carrying out pro-social activities (P < .001); discussing the issue of transplant with the family (P < .001) or couple (P < .001); attitude toward incineration (P < .001), burial (P < .001), and autopsy (P < .001); fear of mutilation after donation (P < .001); and religious beliefs (P < .001). In the multivariate study, it remained an independent variable to have discussed the issue at the family level (odds ratio = 11.627; P = .009). CONCLUSION: The Puerto Rican study population residing in Florida has an unfavorable attitude toward organ donation.

RESUMO

BACKGROUND: The Dominican population has a double-emigration pathway: one is to the USA, by proximity, and the other is to Spain, by sociocultural identification. Our aim was to determine attitudes toward living organ donation among Dominicans residing in Florida (USA) and Spain. METHODS: All study participants were at least 15 years old and living in either Florida (USA) or Spain, and stratified by gender and age. A questionnaire on attitudes toward living kidney donation ("PCID-LKD Ríos") was used. The support of immigrant associations in Florida and Spain was required to advise on survey locations. Data obtained were anonymized and self-administered. RESULTS: The study questionnaire was completed by 123 Dominicans, 68% of whom were in favor of living related kidney donation. There were differences (P = .004) according to the country of residence. Eighty-one percent of Spain's Dominican residents were in favor, compared with 56% of Florida's residents. Factors associated with attitude toward donation were level of education (P < .001), previous experience with organ donation (P = .006), attitude toward cadaveric organ donation (P < .001), belief in the possibility of needing a transplant in the future (P = .016), discussing the issue with one's family (P = .007), discussing the issue with husband/wife/partner (P = .002), carrying out pro-social activities (P = .029), religious beliefs (P = .001), and understanding the risk of living kidney donation (P = .046). CONCLUSION: Attitudes toward living kidney donation among immigrant Dominicans varies between Spain and the USA, with the former showing a more positive view.

RESUMO

BACKGROUND: The Bolivian population is an emerging Latin American immigrant group in Spain, several of whom have been transplanted or are awaiting transplant. We aimed to assess attitudes toward organ donation among Bolivians currently residing in Spain. METHOD: The population screened was born in Bolivia but living in Spain, stratified by gender and age. The appraisal tool used was a questionnaire that assesses attitudes toward organ donation for transplant ("PCID-DTO Ríos"). Support from immigration associations in Spain was needed for advice on locations of potential respondents. Survey participation was anonymized and the questionnaire was self-administered. Verbal consent was obtained before participation. RESULTS: There were 206 respondents: 49% (n = 101) in favor of donating their organs after death; 21% (n = 44) against donation; and 30% (n = 61) undecided. Their attitudes were found to be associated with level of education (P = .008), previous experience with donation and transplant (P = .011), concern regarding mutilation after donation (P = .002), knowing the attitude of their religion toward transplant (P = .001), the opinion of their partner (P < .001), and the possibility of needing a future transplant (P = .050). In the multivariate study, the main factor was having a partner in favor of organ donation (odds ratio = 16.129; P = .003). CONCLUSION: Attitudes toward organ donation among Bolivians residing in Spain are far more negative compared with rest of the Spanish population, due to various factors.

RESUMO

BACKGROUND: One of the main reasons against organ donation is the fear of apparent death due to ignorance of the brain death concept. Our aim was to assess knowledge about and acceptance of the brain death concept among the population of Havana, Cuba. METHODS: The population screened, stratified by gender and age, included those >15 years old and living in Havana, Cuba. The appraisal tool utilized was a questionnaire on attitude toward organ donation ("PCID-DTO Ríos"). A random selection of individuals were surveyed according to the stratification. Cuba's census data were used. The participation was anonymized and self-administered. The verbal consent of participants was provided. RESULTS: There were 920 respondents: 31% (n = 282) knew the concept of brain death and accepted it; 57% (n = 529) did not; and 12% (n = 109) had a misperception, or did not accept brain death as a person's death. Those who knew and accepted the concept had a more favorable attitude toward their own organ donation after death (85% vs 61%; P < .001). The psychosocial factors related to the knowledge of brain death concept were: the gender (P = .002), to make up for speaking at a family level about the organ transplant (P < .001), the couple's opinion about the organ donation (P < .001) and the religion (P < .001). CONCLUSION: The brain death concept is not well understood in the population of Havana, Cuba.

RESUMO

INTRODUCTION: Living kidney donation is currently the most important kidney donor source in Latin America, and it is necessary to further increase its rates. OBJECTIVE: To analyze the attitude toward living kidney donation among the Santiago de Cuba's population and to determine the sociopersonal factors with which it is associated. METHOD: The population over 15 years old residing in Santiago de Cuba, stratified by sex and age, was screened. The "PCID-LKD Ríos" attitude questionnaire toward living kidney donation was administered to a random selection of the people surveyed according to the stratification and the census data. The completion was anonymized and self-administered. Verbal consent was obtained. RESULTS: The study was completed by 445 people, of whom the 86% (n = 389) were in favor of living related kidney donation. This attitude is associated with the level of education (P < .001); previous experience with organ donation (P = .006); attitude toward cadaveric organ donation (P < .001); carrying out of prosocial activities (P = .010); discussion of the issue with the family (P < .001) and the significant other (P < .001); concern about mutilation after donation (P = .001); religious beliefs (P = .001); and assessment of the risk of living kidney donation (P < .001). In the multivariate study, the following variables persisted: (1) level of education; (2) attitude of cadaveric donation; (3) carrying out of prosocial activities; and (4) risk assessment of living donation. CONCLUSIONS: Living related donation is very well accepted among the Santiago de Cuba's population.

RESUMO

INTRODUCTION: Many Africans are emigrating to the European Economic Community from countries with little knowledge of transplantation. This population has not yet been studied. OBJECTIVE: Analyze the attitude toward donation among the Algerian population living in Spain. METHODS: We studied the population born in Algeria and residing in Spain, over 15 years old, and stratified by age and sex. Attitude was surveyed using a questionnaire of organ donation for transplantation ("PCID-DTO Ríos"). Support from African immigration associations was needed to advise on the location of potential respondents. The completion was anonymous and self-administered. Verbal consent was obtained to assist in the study. RESULTS: Of the 441 respondents, 27% (n = 119) were in favor of donation after death, 43% (n = 191) were against, and 30% (n = 131) were undecided. The variables associated with the attitude toward the donation were sex (P = .033), having offspring (P = .027), having commented on the subject of organ transplantation at the family level (P < .001), attitude (P < .001), religion (P < .001), and partner's opinion on organ donation and transplantation (P < .001). Only 16% of the respondents have known a transplant recipient or donor, with this subgroup having the most favorable attitude (68% vs 19%, P < .001). CONCLUSIONS: The Algerian population emigrant to Spain has a very unfriendly attitude toward the donation of their own organs.

RESUMO

INTRODUCTION: The Uruguayan population is sensitized toward transplantation. However, it has not been studied how this awareness can change when emigrating to different countries. OBJECTIVE: To analyze the attitude toward cadaveric organ donation and living organ donation between the Uruguayan population residing in Florida (United States) and the Uruguayan population residing in Spain. METHOD: Adults born in Uruguay and residing in Florida and Spain were screened. The questionnaire "PCID-DTO Ríos" (donation of cadaveric organs) and "PCID-DVR Ríos" (living renal donation) were used. Subjects were randomly selected according to age and gender stratification. Support from Latin-American immigration associations in Spain and Florida was needed. The survey was anonymized and self-administered. Verbal consent was obtained to collaborate in the study. RESULTS: Because the emigrant population to Spain is far larger than the emigrant population to the United States, a 2:1 proportional sampling was performed (n = 132). Sixty-seven percent of residents in Spain were in favor of organ donation at the time of death compared with 50% among residents in Florida (P = .082), and 100% of residents in Spain were in favor of living renal donation compared with 50% of those living in Florida (P < .001). CONCLUSIONS: The attitude toward donation is more favorable among Uruguayan emigrants to Spain than emigrants to the United States, especially in related kidney donation.

RESUMO

BACKGROUND: The Nigerian population is an emerging group in Spain and in Europe, but their sensitization toward living kidney donation has not been studied. The aim of this work was to analyze the attitude toward related renal donation while alive among the population born in Nigeria resident in Spain. METHODS: A population older than 15 years born in Nigeria and resident in Spain, stratified by age and sex, was studied with the use of the attitude questionnaire about living kidney donation, "PCID-DVR-Ríos." People were randomly selected based on stratification. African immigration support associations advised on the location of potential respondents. Completion of the questionnaire was anonymous and self-administered. Verbal consent was requested to assist in the study. Statistical methods included Student t test, χ2, Fisher exact test, and logistic regression analysis. RESULTS: A total of 179 respondents were included in the study: 70% (n = 125) were in favor of living-related kidney donation, and 30% (n = 54) remained against or undecided. This attitude was associated with different psychosocial factors: marital status (P = .001), having offspring (P = .029), risk assessment of live donation (P < .001), partner's opinion about donation (P < .001), previous relationship with donation and/or transplantation (P < .001), religion (P < .001), and fear of mutilation after donation (P < .001). In the multivariate analysis, the previous relationship with donation and/or transplantation (odds ratio, 8.064) persisted as the main related factor. CONCLUSIONS: The Nigerian immigrant population in Spain has a less favorable attitude toward living kidney donation than the native western European and Spanish population.

RESUMO

BACKGROUND: The Ecuadorian population is the largest Latin-American immigrant group in Spain. Currently, several Ecuadorians have received transplants or are awaiting transplants in Spain. The aim of this work was to analyze the attitude toward living kidney donation among the Ecuadorian population residing in Spain. METHODS: The population screened were born in Ecuador, residing in Spain, and >15 years old, stratified by gender and age, and appraised with the use of the questionnaire on attitude toward organ donation for transplantation "PCID-DVR-Ríos." Support from immigration associations in Spain was used to advise on the location of potential respondents. The completion was anonymous and self-administered. Verbal consent was obtained. Statistics included Student t test, χ2, Fisher exact test, and logistic regression analysis. RESULTS: A total of 461 respondents were included: 80% (n = 367) were in favor of living-related kidney donation (for a relative or close friend). This attitude was associated with psychosocial variables that persisted in the multivariate study: 1) female gender (odds ratio [OR], 3.086; P = .001); 2) considering oneself a potential kidney receptor in the future (OR, 16.949; P = .002); 3) economic incentive in the donation (OR, 100; P = .004); and 4) knowing the attitude of their religion toward transplantation (OR, 32.258; P < .001). CONCLUSIONS: Living-related donation is accepted among the Ecuadorian population residing in Spain and is associated with sociopersonal and religious factors.

RESUMO

The application potential of rare earth nitride (REN) materials has been limited due to their high sensitivity to air and moisture leading to facile oxidation upon exposure to ambient conditions. For the growth of device quality films, physical vapor deposition methods, such as molecular beam epitaxy, have been established in the past. In this regard, aluminum nitride (AlN) has been employed as a capping layer to protect the functional gadolinium nitride (GdN) from interaction with the atmosphere. In addition, an AlN buffer was employed between a silicon substrate and GdN serving as a seeding layer for epitaxial growth. In pursuit to grow high-quality GdN thin films by chemical vapor deposition (CVD), this successful concept is transferred to an in situ CVD process. Thereby, AlN thin films are included step-wise in the stack starting with Si/GdN/AlN structures to realize long-term stability of the oxophilic GdN layer. As a second strategy, a Si/AlN/GdN/AlN stacked structure was grown, where the additional buffer layer serves as the seeding layer to promote crystalline GdN growth. In addition, chemical interaction between GdN and the Si substrate can be prevented by spatial segregation. The stacked structures grown for the first time with a continuous CVD process were subjected to a detailed investigation in terms of structure, morphology, and composition, revealing an improved GdN purity with respect to earlier grown CVD thin films. Employing thin AlN buffer layers, the crystallinity of the GdN films on Si(100) could additionally be significantly enhanced. Finally, the magnetic properties of the fabricated stacks were evaluated by performing superconducting quantum interference device measurements, both of the as-deposited films and after exposure to ambient conditions, suggesting superparamagnetism of ferromagnetic GdN grains. The consistency of the magnetic properties precludes oxidation of the REN material due to the amorphous AlN capping layer.
