Relationship of trust on selected health information sources and COVID-19 vaccine acceptance among older adults / The Health Sciences Journal

Introduction@#In order to suppress the COVID-19 virus, several vaccines have been developed. The administration of COVID-19 vaccines entails its acceptance. However, misinformation and vaccine uncertainty are main factors that affect vaccine acceptance. This study aimed to determine the most trusted health information source, the most frequently accessed health information source, and health literacy of older adults within Metro Manila. @*Methods@#This study employed a quantitative non-experimental design utilizing correlational and descriptive approaches. Convenience sampling was utilized via Facebook to recruit participants. The survey was adapted from four different questionnaires and went through reliability testing and expert validation. @*Results@#The researchers collected responses from a total of 123 participants. The participants were noted to have an overall high level of acceptance for the COVID-19 vaccine ( 4.10, SD ± 0.22). The study revealed that doctors were the highly trusted health information source (( =3.69, SD ± 1.30), followed by government health agencies (( =3.18, SD ± 0.73), whereas religious organizations and leaders (( =2.45, SD ± 0.48) were the least trusted sources. However, despite being the least trusted source, religious organizations and leaders were shown to be positively related (p=0.049) and highly predictive of COVID-19 vaccine acceptance. The most frequently accessed health information source, health workers, have a weak correlation (r=.323) and were found to be significantly positively related (p=0.008) and highly predictive of the acceptance of the COVID-19 vaccine. The credibility of health information sources is likely to influence their selection, influencing decisions and behaviors.

Approximately 75.4% of respondents indicated that they either “understood” or “understood well” the standard; 42.86% received relevant training; 45.24% and 54.76% indicated that the standard “met” or “basically met” the requirements of detection of γ-ray radiotherapy equipment shielding or design of shielding room. The standard was highly evaluated for suitability. However, the awareness of the standard was inadequate, the rate of training participation was low, and its practical application was limited. Conclusion The standard generally aligns with the requirements for shielding room design in γ-ray radiotherapy. Some revisions should be done according to the current situation of γ-ray radiotherapy.

Research progress on the effects of fine particulate components exposure on cardiovascular metabolic diseases / 公共卫生与预防医学

Exposure to fine particulate (PM2.5) has become a serious environmental risk factor threatening public health. A large number of epidemiological studies have shown that PM2.5 exposure is significantly associated with cardiovascular health.  At present, studies have found that PM2.5 components are associated with the incidence and death of cardiovascular metabolic diseases (hypertension, diabetes, coronary heart disease, stroke, etc.), which may be due to the different components of PM2.5 in different regions, which have different effects on cardiovascular health.  This article reviews the effects of different components of PM2.5 on cardiovascular metabolic diseases based on their sources and pathogenesis. The limitations of the effects of PM2.5 components on cardiovascular metabolic diseases are also discussed.

Ilegítimos na transição entre o Império e a República: o caso do estado de São Paulo (1886-1900) / Illegitimacy in the transition between the Empire and the Republic: the case of the state of São Paulo (1886-1900) / Ilegítimos en la transición entre el imperio y la república: el caso del estado de São Paulo (1886-1900)

Resumo No Brasil, o estudo da condição de legitimidade (filiação) é tópico que vem sendo tratado pela literatura especializada, tanto no âmbito da História quanto no da Demografia Histórica, sobretudo a partir da década de 1980. O objetivo deste artigo é contribuir para o avanço da temática, mapeando a incidência e a distribuição espacial da ilegitimidade no estado de São Paulo, no final do século XIX, a partir de uma perspectiva diferente daquela dos estudos já elaborados, especialmente em relação ao recorte temporal e às fontes utilizadas. Assim, foram analisados os dados sobre a filiação na população paulista a partir dos Recenseamentos Gerais da População Brasileira, realizados em 1890 e 1900, acrescidos de outras fontes de cunho estatístico, produzidas para o estado de São Paulo. Os resultados apontam um quadro diferenciado em relação às várias zonas que compõem o estado e, embora as fontes sejam distintas, corroboraram o papel fundamental da imigração internacional, pois, nas áreas onde ela foi mais intensa, verificou-se a queda nos percentuais da ilegitimidade.

Abstract In Brazil, the study of the condition of legitimacy (affiliation) is a topic that has been studied by the specialized literature, both in the field of History and in that of Historical Demography, especially from the 1980s onwards. The objective of this article is to contribute to the advancement of the debate on illegitimacy, mapping the incidence and the spatial distribution of the phenomenon in the state of São Paulo, at the end of the 19th century, from a different perspective of previous studies, especially in relation to the considered period and the used sources. Thus, data on affiliation in the São Paulo population were analysed from the General Censuses of the Brazilian Population, carried out in 1890 and 1900, in addition to other statistical sources produced for the state of São Paulo. The results point to a different picture in relation to the various zones that make up the state of São Paulo and, although the sources are different, the results corroborate the fundamental role of international immigration, because in the areas where it was more intense, there was a decrease in the percentages of illegitimacy.

Resumen En Brasil, el estudio de la condición de legitimidad (filiación) es un tema que viene siendo abordado por la literatura especializada tanto en el campo de la Historia como en el de la Demografía Histórica, especialmente a partir de la década del ochenta del siglo XX. Es nuestra intención contribuir al avance del tema, mapeando la incidencia y la distribución espacial de la ilegitimidad en el estado de São Paulo, a finales del siglo XIX, desde una perspectiva diferente a la de estudios anteriores, en especial en relación con el marco temporal y las fuentes utilizadas. Así, los datos de afiliación en la población paulista fueron analizados a partir de los censos generales de población brasileña de 1890 y de 1900, además de otras fuentes estadísticas producidas para el estado de São Paulo. Los resultados apuntan a un cuadro diferente en relación con las diversas zonas que componen el estado de São Paulo y, aunque las fuentes son diferentes, los resultados corroboran el papel fundamental de la inmigración internacional, pues en las áreas donde fue más intensa disminuyeron los porcentajes de ilegitimidad.

Rapid identification and differential markers of Curcumae Radix decoction pieces of different sources based on Heracles Neo ultra-fast gas phase electronic nose / 中国中药杂志

Since Curcumae Radix decoction pieces have multiple sources, it is difficult to distinguish depending on traditional cha-racters, and the mixed use of multi-source Curcumae Radix will affect its clinical efficacy. Heracles Neo ultra-fast gas phase electronic nose was used in this study to quickly identify and analyze the odor components of 40 batches of Curcumae Radix samples from Sichuan, Zhejiang, and Guangxi. Based on the odor fingerprints established for Curcumae Radix decoction pieces of multiple sources, the odor components was identified and analyzed, and the chromatographic peaks were processed and analyzed to establish a rapid identification method. Principal component analysis(PCA), discriminant factor analysis(DFA), and soft independent modeling cluster analysis(SIMCA) were constructed for verification. At the same time, one-way analysis of variance(ANOVA) combined with variable importance in projection(VIP) was employed to screen out the odor components with P<0.05 and VIP>1, and 13 odor components such as β-caryophyllene and limonene were hypothesized as the odor differential markers of Curcumae Radix decoction pieces of diffe-rent sources. The results showed that Heracles Neo ultra-fast gas phase electronic nose can well analyze the odor characteristics and rapidly and accurately discriminate Curcumae Radix decoction pieces of different sources. It can be applied to the quality control(e.g., online detection) in the production of Curcumae Radix decoction pieces. This study provides a new method and idea for the rapid identification and quality control of Curcumae Radix decoction pieces.

Percepciones asociadas a conductas sexuales de riesgo / Perceptions associated with risky sexual behaviors

Resumen: Objetivo: Identificar en un grupo de jóvenes tabasqueños las percepciones asociadas con conductas sexuales de riesgo. Material y métodos: Se trata de un estudio mixto y transversal, realizado con un muestreo no probabilístico a conveniencia de 60 personas, quienes cumplían con los criterios de inclusión (18-25 años) pertenecientes al estado de Tabasco, 30 hombres y 30 mujeres. Se les aplicó la encuesta de salud y hábitos sexuales. Resultados: Las mujeres señalaron como sus mayores fuentes de educación sexual a los médicos (30%) y a sus madres (23%); mientras que, en el grupo de los hombres, fueron médicos, amistades, libros, etc. Para la percepción de riesgo de contraer VIH con el comportamiento sexual actual, los hombres percibieron mayor riesgo de contagio que las mujeres. Relacionado con las medidas que protegen del VIH, el uso del preservativo fue el método identificado como el más seguro, tanto en hombres (96.66%) como en mujeres (100%). En segundo lugar, se reconoció la opción "hacerse pruebas con frecuencia"; sin embargo, el 65% señaló nunca haberse realizado la prueba de VIH. Acerca del uso de los preservativos, en ambos grupos, predominaron respuestas, tales como, "son complicados de usar", "crean desconfianza en la pareja", entre otras. Sobre la percepción de los mecanismos a través de los cuales se podría adquirir el VIH, los 60 (100%) encuestados marcaron que el VIH se transmite a través de las relaciones sexuales; sin embargo, la opción "por picadura de mosquito" fue elegida por 3 (10%) hombres y una mujer (3.33%). Conclusiones: Las percepciones erróneas pueden ser determinantes para acceder a prácticas sexuales inseguras. Identificar las percepciones equivocadas, las fuentes, calidad y veracidad de la información en temas de sexualidad, así como los factores de riesgo y de protección, puede servir para diseñar intervenciones psicoeducativas eficientes, como estrategia de prevención para los adolescentes y los jóvenes.

Abstract: Objective: To identify youth perceptions associated to risky sexual behaviors in a group of teenagers from Tabasco. Material and methods: It is a mixed, cross-sectional study with a non-probabilistic sampling which was carried out at the convenience of 60 people who met the inclusion criteria (18-25 years old) belonging to the state of Tabasco, consisting of 30 women and 30 men. Health and sexual habits surveys were applied to them. Results: Women indicated doctors (30%) and their mothers (23%) as their main sources of sexual education; while, in the group of men, they referred to doctors, friends, books, etc. For the perception of risk of acquiring HIV with current sexual behavior, men perceived a higher risk of infection in comparison to women. In relation of measures that protect against HIV, the use of condoms was identified as the safest method, both in men (96.66%) and in women (100%). The second safest option they referred to was "to get tested frequently"; however, 65% reported never having an HIV test in the past. Regarding the use of condoms, in both groups, responses predominated, such as, "they are difficult to use", "they create mistrust in the partner", among others. Concerning about the perception of mechanisms through which HIV could be acquired, 60 participants (100%) indicated that HIV is transmitted through sexual intercourse; however, the option "by mosquito bite" was chosen by 3 men (10%) and one woman (3.33%). Conclusions: Wrongful perceptions can be decisive in the practice of unsafe sexual practices. Identifying misperceptions, sources, quality and veracity of information on sexuality issues, as well as risk and protective factors, can be useful to design efficient psychoeducational interventions as a prevention strategy for adolescents and the youth.

A utilização de tubo de PVC proporciona um aumento de peso e concentração de OD em relação ao sistema de mangueiras difusoras com 22% e 28% de proteína bruta.

Prevalence of Vibrio species in Sea Foods and Water Sources in Cross River State

In the coastal areas of the world, most Vibrio species have been incriminated as notorious agents causing foodborne, wound and other infections. These pathogens are known to be associated with the consumption of raw or undercooked seafoods or the exposure of wounds to warm seawater. Aim: Therefore, this research work was designed with the aim of assessing the microbiological quality of the water bodies as well as the seafoods consumed in Cross River State (CRS). Study Design: The Study was designed using the completely randomized block design and the data was analyzed using of two-way analysis of variance, Generalized Linear Model Univariate analysis. Significant means were separated using the Least significant difference (LSD). Place and Duration of Study: This study was done in the Department of Microbiology, University of CRS, Calabar, CRS, Nigeria, between 2016-2019. Methodology: we evaluated a variety of seafoods viz; crayfish, blue crabs, Periwinkles, apple nails, red lobsters etc. collected from major Beaches, markets and other sale points and water sources (rivers streams sea and gutters) in Calabar, CRS of Nigeria, using standard bacteriological techniques, for the prevalence of Vibrio species. Results: The mean percentage mean viable cell counts obtained ranged from 1.79�45 (seawater)-9.15�79CFU/mL (gutter water) and 7.68�58 (Blue Crab)- 11.37�82 CFU/g (fish) in the Rainy season. The counts for the Dry season Ranged from 1.79 �42 (Seawater)-8.94� 4.51(gutter water), and 5.83 7.21 CFU/g (apple snail) -12.64 5.95 CFU/g (Fish). The total percentage mean counts obtained were 8.09�91 CFU/mL in the Rainy Season to 7.61�58 CFU/mL in the dry Season. From both seasons, the overall total mean count was 11.09�94 CFU/ml. From the nine locations evaluated in this study, it was observed that the Mean percentage counts for the Northern Senatorial District (NSD) ranged from 2.81� 3.49 (Ogoja)- 3.14 �07CFU/mL (Obudu). For the Central (CSD) the range was from 3.34 �20 (Boki)- 9.89 �15 (Ikom), while for the Southern (SSD) it was from12.01� 6.52 (Akamkpa)- 14.47 �44 (Calabar). The overall Total percentage mean counts from all the three Senatorial Districts was 14.03�86 CFU/mL. From the Northern Senatorial District, the total Percentage mean was 3.01�77 CFU/mL, 7.05�79 CFU/mL from the Central and 13.49� 5.72 CFU/mL from the Southern Senatorial District. The Vibrio pathotypes isolated include Vibrio cholerae (V. cholerae) (both O1 and non-O1 serotypes) 1155 (31.61%), Vibrio parahaemolyticus (V. parahaemolyticus), 752 (20.58%), Vibrio fluvialis (V. fluvialis) 480 (13.14%), V. vulnificus 473 (12.94%) Vibrio mimicus (V. mimicus) 400 (10.95%) and Other Vibrios 394 (10.78%). Out of the 3654 Vibrio isolates, the greatest number 663�31 (18.14%) were from Seawater, while the least 133�.84 (3.64%) were from the Gutter Water. Also, the highest number 1245�61 (34.07%) came from Calabar, and the least 102�.65 (2.79%) from Obanlikwu. The NSD had the least number 327 (8.95%), followed by the CSD with 570 (15.59%) and then the SSD with 2757 (75.45%) as the highest number of isolates. Conclusion: The presence of these pathogenic bacterial species in common seafoods in this area is of great public health concern. It is therefore important that serious emphasis be laid on proper cooking of these seafoods as well as the establishment of regular hygiene surveillance strategies in the state.

Perceptions and Attitudes of Hospital' Prescribers towards Drug Information Sources and Prescribing Practices

Abstract Healthcare professionals use a variety of drug information sources to fulfill their clinical needs and medical practice. The aim of present study was to assess the sources of drug information among hospital' prescribers and evaluate their prescribing behavior in Saudi hospitals. A cross-sectional survey was conducted among randomly selected hospital' prescribers using a self-administered questionnaire. The response rate to the survey was 64.29%, with a ratio of 76.44% male and 23.56% female. The internet 137(60.89%) and textbooks 86(38.22%) were the prevalent sources for drug information used. Up-To-Date 107(47.56%), Medscape 105(46.67%) and FDA 74(32.88%) were the common electronic drug sources used. About 151(67.11%) of hospital' prescribers considered the pharmacist as a reliable drug information source. The most favored drug requests by hospital' prescribers from the pharmacists were drug alternatives 110(48.89%) followed by drug interactions 94(41.78%), side effects 78(34.67%) and indications 60(26.67%). Therapeutic efficacy 168(74.67%) and drug availability 73(32.44%) were the main factors contributed to the selection of drugs. This study shows some differences in hospital prescribers' perceptions of sources of drug information depending upon their background and clinical practice. Therefore, knowing appropriate drug information used by hospital' prescribers is fundamental for drug efficacy and safety in clinical practice.

Los comités de bioética. Aspectos de interés en la relación entre bioética y derecho / Bioethics committees. Aspects of Interest in the Relationship Between Bioethics and Law / Comitês de Bioética. Aspectos de interesse na relação entre bioética e direito

Resumen: Los comités de bioética apoyan las instancias sociales y gubernamentales que se encargan de la toma de decisiones en cuestiones relacionadas con el desarrollo de las nuevas tecnologías sobre la vida. Estas cuestiones se caracterizan por su problematicidad y conflictividad. Las reflexiones y decisiones que provienen de los comités de bioética las podemos analizar en relación con las fuentes del derecho. Siendo así, hay que admitir que el derecho ha de abrirse a otra clase de discursos, lo que toca el corazón mismo de la ciencia del derecho. El artículo presenta del objeto de investigación explicando varios aspectos que se consideran relevantes para entender la relación que se da entre bioética y derecho; luego, desarrolla una discusión a partir de unos elementos críticos o teóricos a partir de los resultados encontrados en la búsqueda bibliográfica; por último, el artículo formula una tesis o solución. El método que se sigue es analítico-sintético. El artículo no se ocupa, propiamente, de dar soluciones prácticas a los problemas en bioética, como sí de analizar, de forma general, un nuevo campo de interacción entre la bioética y el derecho.

Abstract: The bioethics committees support the social and governmental instances that are responsible for making decisions on issues related to the development of new technologies on life. These issues are characterized by their problematic and conflictive nature. The reflections and decisions that come from the bioethics committees can be analyzed in relation to the sources of law. This being the case, it must be admitted that the law has to open itself to another class of discourses, which touches the very heart of the science of law. The article presents the object of the research explaining several aspects that are considered relevant to understanding the relationship between bioethics and law; then, it develops a discussion based on some critical or theoretical elements based on the results found in the bibliographic search; finally, the article formulates a thesis or solution. The method followed is analytical-synthetic. Strictly speaking, the article does not deal with providing practical solutions to problems in bioethics, but rather with analyzing, in a general way, a new field of interaction between bioethics and law.

Evaluation of the chemical profile from four germplasms sources of Pruni Semen using UHPLC-LTQ-Orbitrap-MS and multivariate analyses / 药物分析学报

Pruni Semen,the seed of several unique Prunus plants,is a traditional purgative herbal material.To determine the authentic sources of Pruni Semen,46 samples from four species were collected and analyzed.Ten compounds including multiflorin A(Mul A),a notable purative compound,were isolated and identified by chemical separation and nuclear magnetic resonance spectroscopy.Seventy-six communal components were identified by ultra-high performance liquid chromatography with linear ion trap-quadrupole Orbitrap mass spectrometry,and acetyl flavonoid glycosides were recognized as characteristic constituents.The flavonoids were distributed in the seed coat and cyanogenic glycosides in the kernel.Based on this,methods for identifying Pruni Semen from different sources were established using chemical fingerprinting,quantitative analysis of the eight principal compounds,hierarchical cluster analysis,principal component analysis,and orthogonal partial least squares discriminant analysis.The results showed that the samples were divided into two categories:one is the small seeds from Prunus humilis(Ph)and Prunus japonica(Pj),and the other is the big seeds from Prunus pedunculata(Pp)and Prunus triloba(Pt).The average content of Mul A was 3.02.6.93,0.40,and 0.29 mg/g,while the average content of amygdalin was 18.5,17.7,31.5,and 30.9 mg/g in Ph,Pj,Pp,and Pt,respectively.All the above information suggests that small seeds might be superior sources of Pruni Semen.This is the first comprehensive report on the identification of chemical components in Pruni Semen from different species.

Association between willingness to receive the COVID-19 vaccine and sources of health information among Japanese workers: a cohort study

BACKGROUND@#It is important to achieve herd immunity by vaccinating as many people as possible to end the COVID-19 pandemic. We investigated the relationship between willingness to receive vaccination and sources of health information among those who did not want to be vaccinated against COVID-19.@*METHODS@#This prospective cohort study collected data using a self-administered questionnaire survey. The baseline survey was conducted during December 22-25, 2020, and the follow-up survey during February 18-19, 2021. Participants were aged 20-65 years and worked at the time of the baseline survey (N = 33,087). After excluding 6,051 invalid responses, we included responses from 27,036 participants at baseline. In total, 19,941 people responded to the follow-up survey (74% follow-up rate). We excluded 7,415 participants who answered "yes" to the question "If a COVID-19 vaccine becomes available, would you like to get it?" in the baseline survey. We finally analyzed 12,526 participants.@*RESULTS@#The odds ratio for change in willingness to be vaccinated from "no" to "yes" differed by source of health information. Compared with workers that used TV as a source of information, significantly fewer people who reported getting information from the Internet and friends/colleagues were willing to get the vaccine.@*CONCLUSIONS@#It is important to approach workers who do not watch TV when implementing workplace vaccination programs. It is likely that willingness to be vaccinated can be increased through an active company policy whereby the top management recommend vaccination, coupled with an individual approach by occupational health professionals.@*TRIAL REGISTRATION@#Not applicable.
