Published: April 2024

Escherichia coli commonly occurs as a normal flora found in a variety of gastrointestinal tracts. However, certain strains acquire virulence characteristics. Potentially pathogenic species have also been isolated in non-clinical environments.This often raises concerns on the role these environments play in transmission. This study aimed to assess the occurrence of virulence traits in Escherichia coli isolated from non-clinical and clinical sources in Port Harcourt, Nigeria. Two hundred samples from clinical (urine and stool) and non-clinical (soil and poultry) sources were analyzed. 8 isolation, purification and identification of E. coli isolates were performed using standard bacteriological and biochemical tests. Out of the 200 samples collected, 98 isolates (49%) were confirmed as E. coli. Confirmed E. coli isolates were then tested for virulence using standard phenotypic tests (protease, colicin, congo red, hemolysin, haemagglutination, adhesin and mannose resistant/sensitive haemagglutination). E. coli strains from clinical samples displayed a number of virulence traits ranging frombiofilm producing capabilities (53%), congo red binding propensity (24%), colicin (34%), protease (15%) and hemolysin production (4%) compared to their non-clinical counterpart. All samples were negative for haemagglutination. The total virulence prevalence of E. coli was 81%. Clinical samples possessed more virulence traits (71%) than samples from non-clinical sources (29%), with urine having a higher occurrence among the clinical samples (36%). There is need for an in-depth study on virulence attributes of E. coli and ways to control these factors to minimize the rate of spread and the degree of infections.

Malaria remains a disease of public concern according to reports by the World Health Organization which recommends diverse therapeutic approach including the use of plant derived products to combat drug resistance in malaria treated individuals. This study therefore, evaluates the antiplasmodial effects of black seeds (Nigella sativa), fenugreek (Trigonella foenum-graecum) and coriander seeds (Coriandrum sativum) and their effects on packed cell volume and weight of experimental mice. Phytochemical analysis of the extract was conducted using Gas Chromatography-Mass Spectrometry analysis to establish the presence of antimalarial constituents. The plant extracts were screened for curative activities at dosages of 50mg/kg, 100mg/kg and 200mg/kg, in mice inoculated with Plasmodium berghei from donor mice. Chloroquine (6mg/kg body weight) was used as standard control drug. A 4-day curative assay was used to evaluate the antimalarial potentials of the plant extracts. Comparison between treated samples were analyzed using single factor analysis of variance at 95% confidence interval and 5% significance level (P<0.05). The results obtained from this study revealed significant suppression rate at 50mg/kg for Nigella sativa (67.0%), 200mg/kg for Trigonella foenum-graecum (68.3%), and 200mg/kg for Coriandrum sativum (66.7%). Chloroquine (6mg/kg) showed a higher inhibitory performance at 86.6% on day 7 post treatment compared to the plant extracts. The packed cell volume increased in groups treated with chloroquine compared to the extract treated group while the weight of mice increased in all extract groups significantly compared to the chloroquine treated group. The results of the study were statistically significant at P<0.05.

A comparative study on the genotoxic effect of radiation from X-rays of different levels on Mussel gill cells, haemocyte and human lung cell A549 using the comet assay was carried out. The results revealed an increasing DNA damage with increasing doses of X-ray, single strand breaks and alkali labile sites in the haemocyte of the control had a mean value of 5.92 ± 1.27 while the highest treatment group 15Gray (Gy) had a mean value of 78.65 ± 4.36,withsignificant differences (P <0.05), A mean value of 21.10 ± 13.10 was recorded for Mussel gill cells in the control group while the highest treatment group 15 Gray (Gy) had 85.55 ± 1.43. Statistical analysis revealed significant differences (P <0.05) for univariate tests of the control group and the treatment groups. The A549 human lung cells had a minimal damage in the control group 2.30 ± 0.30 while the highest exposed group had a mean value from the median % tail intensity of 43.10 ± 2.81. Pair wise comparison of gills cells, haemocytes from mussels and A549 human lung cells exposed to 15 Gy of X-rays shows that the highest damaging effect was observed on the gill cells followed by the haemocytes with the least damaging effect on the A549 human lung cells exposed to the same dose rate of X-rays with significant differences (P <0.05) between them.This study revealed that A549 human lung cells were more resistant to DNA damage induced by the X-rays when compared to mussel gill and haemocyte cells and also indicates that mussel gill cells and haemocytes can serve as biomarkers of genotoxicity of radiation exposure using the comet assay.

Published: April 2024

Kappa casein and beta lactoglobulin genes are major milk proteins which have a direct effect on protein content in dairy cattle. Molecular-based selection through the identification of genetic polymorphism of major protein genes can be used to gain genetic improvement of milk protein yield. The objective of this study was to identify kappa casein (CSN3) and beta lactoglobulin (LGB) genes polymorphisms in indigenous and crossbreed cattle. A total of 90 whole blood samples were collected from individual animal in a private dairy farm. DNA extraction and quality assessment were done salting out procedure and gel electrophoresis, respectively. Polymerase chain reaction (PCR) was performed with gene specific primers. For genotyping, PCR products of CSN3 gene was digested with HinfI and HindIII while LGB gene was digested with HaeIII restriction enzymes. Two haplotypes A and B; three genotypes, AA, AB and BB were observed at CSN3 of HinfI site and LGB HaeIII site, but only AA and AB were observed at CSN3 of HindIII site in crossbred and indigenous cattle populations. However, at CSN3 locus, A allele was found to be more common (0.65) in indigenous cattle than the B allele (0.35), while B (0.51) allele and AB genotype (0.81) were more frequent in crossbred cattle. But, LGB B allele was higher in indigenous cattle (0.67) compared to Allele A (0.33). LGB BB genotype (0.57) is higher followed by AA genotype in indigenous cattle while both allele and genotypic frequencies are equal in crossbred cattle. Both CSN3 and LGB loci were polymorphic in studied populations. Expected heterozygosity was higher in crossbred (0.49, 0.50) than in indigenous (0.38, 0.33) cattle at CSN3 and LGB locus, respectively which might be due to breed variation. The current findings showed that both CSN3 and LGB genes could be promising diagnostic markers in selecting dairy cattle breed. However, further investigations with large sample size and association study with milk composition is required to substantiate the current result.

Background/Aim: Juvenile Onset Recurrent Respiratory Papillomatosis (JoRRP) is a benign tumour attributed to human papillomavirus infection with a high propensity to recur despite appropriate treatment. It is relatively rare but the commonest benign tumour of the larynx in children. This study is aimed at evaluating its management challenges.

Materials and methods: This was a retrospective review of patients with JoRRP at Ear, Nose and Throat (ENT) Department, University of Ilorin Teaching Hospital over a 7-year period. The patients' biodata, mode of presentations, surgical care, histopathological findings and management outcome were reviewed.

Results: A total number of ten patients were diagnosed with JoRRP during the study period. Male to female ratio was 1:1. All the children were delivered per vaginal and sixty percent were first children of their mothers. Hoarseness, breathy voice and worsening difficulty in breathing were the presentation in 7 (70%) of cases, while 3 (30%) presented with only hoarseness and breathy voice. They all presented first to General Practitioners and Paediatricians before ENT Specialist assessment and six (60%) patients presented to ENT department 6 months or more after the onset of symptoms. They all had direct laryngoscopy and excisional biopsy of laryngeal papillomatous lesions. Thirty percent had tracheostomy done. There is a statistical significant relationship between tracheostomy rate and recurrence rate of JoRRP.

Conclusion: JoRRP is a rare but potentially life-threatening benign tumor of the respiratory tract. Most of our patients presented late and were misdiagnosed at presentation. The key to good management outcome remains early diagnosis, adequate management and regular follow-up.

Background: Prostate biopsy is one of the most performed urological procedures. It is a generally safe procedure, however, there has been increasing incidence of life-threatening infective complications such as sepsis due to a global rise in antibiotic resistance.

Methodology: This study aimed to determine whether targeted antibiotic prophylaxis using rectal swab MCS-directed antibiotics is more effective than empirical antibiotic prophylaxis in preventing infective complications after transrectal prostatic needle biopsy at a Nigerian Teaching Hospital. Ninety-two consenting patients were prospectively randomized into 2 equal arms using a computer-generated random sequence. Forty-six patients received targeted antibiotic prophylaxis based on rectal swab MCS, while the remainder received empirical antibiotic prophylaxis as per local protocol. All patients underwent sextant transrectal prostatic needle biopsy and were subsequently followed up for 1months to assess for infective complications. The data were analyzed using SPSS version 21. Statistical significance was set at P ≤0.05.

Results: The average age of the patients studied was 68.3yrs (48-91±8.3yrs). Both groups were comparable at baseline. Overall, there were 7(7.6%) cases of infectious complications. Most of these complications occurred in the empirical prophylaxis group (6 (13 %) vs. 1 (2 %), P– 0.049). These were also more severe than those in the targeted arm.

Conclusions: Targeted antibiotic prophylaxis was associated with a significant decrease in the incidence of infectious complications compared with empirical antibiotic prophylaxis after transrectal prostate needle biopsy. This method should be considered in patients at a high risk of infective complications.

Authors: Abraham Zephania , Daudi Irene , Kahinga Aveline
Published: April 2024

Introduction: Head and neck lesions associated with Human Immunodeficiency Virus are considered to occur in over 50% of HIV- positive patients and occur in nearly 80% of all patients with acquired immunodeficiency syndrome. The introduction of highly active antiretroviral therapy has led to a remarkable reduction in the global burden of such lesions. Suppose such lesions are undiagnosed or untreated on a prompt basis. In that case, they may cause morbidity and mortality since some lesions, for example, head and neck cancers may interfere with vital functions of life such as respiration, deglutition, and speech. This study determined head and neck lesions among HIV/AIDS patients in Tanzania.
Methods: This was a hospital-based descriptive cross-sectional study that recruited 222 HIV/AIDS patients at a care and treatment clinic at Dodoma Regional Referral Hospital.  Physical examination and laboratory investigations (histopathology, viral load and CD4 counts) were collected and data was analyzed using Statistical Package for Social Sciences (SPSS) version 23. P-value<0.05 was statistically significant.
Results: Of all the 222 patients recruited in this study, 26 (11.7%) had head and neck lesions. Most patients with head and neck lesions were females (57.6%). Half of the patients (50.0%) were between 40 and 59 years old. About 21 (80.8%) patients were diagnosed with HIV/AIDS within two years, and 22 (84.6%) were initially diagnosed with CD4 counts less than 200 cells/μL. The most common head and neck lesion was oral candidiasis (46.2%) and others were cervicofacial lymphadenitis (15.4%), head and neck squamous cell carcinoma (laryngeal and hypopharyngeal) (11.5%), sinonasal Kaposi’s sarcoma (7.7%), odontogenic abscess (7.7%) and aphthous ulcers (7.7%) and the least encountered head and neck lesion was a ranula in 3.8% of patients. Similarly, a significant association was found between the occurrence of head and neck lesions with viral load, CD4 counts, duration since a patient was diagnosed with HIV/AIDS, presence of comorbid illness, alcohol consumption and cigarette smoking.
Conclusions: The prevalence of head and neck lesions among HIV/AIDS patients on HAART was low. Females outnumbered males in terms of being affected by head and neck lesions. Oral candidiasis was the most common head and neck lesion. Head and neck (laryngeal and hypopharyngeal) squamous cell carcinoma was the predominant subtype of malignant lesions in HIV/AIDS patients on HAART.

Introduction: Diabetes-related complications are the significant causes of morbidity and mortality among type 2 diabetes patients. The complications can be reduced by practicing and maintaining several preventive measures. The present study aims to assess compliance and factors associated with recommended management practices and prevention of complications among type 2 diabetes patients in selected health facilities in Morogoro Municipality, Tanzania.
Methods: A hospital-based cross-sectional study was conducted from February to May 2023 among 140 patients, including patients who were diagnosed with diabetes for at least three months prior to the study. Data were collected through face-to-face interviews using a structured questionnaire, which included patients’ characteristics and a previously validated Summary of Diabetes Self-care Activities questionnaire to assess patients' compliance with recommended practices. A multivariable regression analysis was employed to identify factors associated with compliance with recommended practices.
Results: The mean age of the respondents was 59 ±12.08 years and 65% were females. Among 140 patients, 91.4% (n=128) had poor or unsatisfactory self-care practices with an overall mean of 3.81± 2.08 days per week for diabetes management. The recommended practices with good or satisfactory performance were non-smoking, non-alcohol drinking and prescribed medication. In contrast, unsatisfactory performance was observed for self-monitoring of blood glucose with a mean of physical activity. Multiple regression analysis showed that co-morbidity (AOR 4.5; 95% CI:1.14-18.02) and being employed (AOR 4.4; 95% CI:1.25-15.44) independently predict self-care practices.
Conclusion and recommendation: Compliance with self-monitoring of blood glucose, physical exercise and dietary practices were found to be low among type 2 diabetes patients, which could increase the risk of complications. Nutritional and lifestyle counselling and the use of peer groups should be emphasized to improve compliance with recommended practices.

Background: Delayed Developmental Milestones are defined as slow to attain typical developmental milestones in one or more developmental areas. This study aimed to assess risk factors of delayed developmental milestones among infants in the Dodoma Region.
Methods: We conducted a health facility-based cross-sectional descriptive study using the pathways developmental screening tool. A total of 262 mothers with their children were enrolled, the study population were all neonates delivered at the study sites during the study period. Three data collection methods were utilized to obtain information for this study: observation, interviewer-administered questionnaires, and documentary review. Ethical approval was obtained from the Ethical Review Board of the University of Dodoma SAS version 9.4 was used for data analysis. The association between developmental status and factors was assessed with Chi-square and binomial logistic regression.
Results: Notably, infants born with birth asphyxia were more likely three times to develop delayed developmental milestones as opposed to those without birth asphyxia [adjusted risk ratio =3.22, 95%, [1.97, 5.46], probability value= <.0001]. Birth weight was significantly associated with delayed developmental milestones; infants who were born with a birth weight of ≥4000gm had more risk of developing delayed developmental milestones compared to those with a birth weight of 2500-3999gm [adjusted risk ratio 0.48, 95%, [0.26, 0.92], probability value = 0.0256]. Regarding mode of delivery, the risk of developing delayed developmental milestones was less among infants born via caesarean section compared to those who were born via spontaneous vaginal delivery [adjusted risk ratio 0.47[0.18, 0.99], probability value = 0.0461].
Conclusion: Delayed developmental milestones are a burden in developing countries. The risk factors are known, and they are based on the individual to the community level; birth asphyxia was identified as a possible risk factor that has been reported in many studies and has an impact on children's development.

PT. Asia Chemical Industry (ACI) is a company engaged in the field of Chemical Adhesives. It is management policy to produce high quality and consistent Adhesives. In accordance with the standards determined by consumers and always maintain customer satisfaction with quality standards through specification information that is included in every shipment, sale, in addition to competitive price factors from similar companies. The adhesive in the process often experiences production delays caused by the adhesive machine (waterbase latex mixer) caused by non-routine maintenance of machine components so that the machine production is damaged which causes breakdown, resulting in downtime. As a result, the performance time is reduced, the production of the resulting product quality results in losses. Therefore, an effective step in the analysis of total predictive maintenance to measure the performance level of the adhesive machine can use the OEE method to determine the performance level of the adhesive machine that has decreased, and the FMEA method to analyze the proposed improvement. From the research conducted, the results of the OEE calculation on the adhesive machine during the period January - December 2021 obtained OEE values ​​ranging from 69.02% to 81.40%. This condition indicates that the adhesive machine's ability to achieve the target has not yet reached the ideal condition, which is below 85%. . The factor that gives the biggest contribution to the adhesive machine, namely the performance efficiency factor, has caused a decrease in the performance level of the machine, causing downtime

A través de esta páginas, nos acercamos a todos los campos en los que actualmente trabajamos los que hacemos historia de la Iglesia: archivos y repertorios bibliográficos, las diócesis, las personas –prelados, cabildos, bajo clero, religiosos y el mundo de los seglares-, rentas eclesiásticas, acción benéfica y caritativa de la Iglesia, religiosidad popular, santoral y hagiografía, expresiones artísticas y el mundo de la heterodoxia –minorías religiosas, Inquisición, anticlericalismo y antimasonismo-. También aparecerán en este trabajo las tendencias y perspectivas de la investigación sobre la historia de la Iglesia andaluza. En definitiva, el largo camino que aún nos queda por recorrer.
Arquitectura y Derecho: la impronta de las reglas monásticas en el proceso constructivo de los espacios conventuales
Authors: Gabardón de la Banda José Fernando
Published: April 2024

La pronta publicación de una monografía dedicada a la arquitectura conventual sevillana me ha llevado a escribir a modo de síntesis para el presente Anuario de la historia de la Iglesia sevillana una recopilación de los más importantes hitos arquitectónicos del mundo conventual hispalense. El hilo conductor de este estudio se centra en la impronta que tuvo la normativa salida de los textos reglamentarios o de los propios textos de santos y fundadores de las órdenes en los procesos constructivos, que en principiose caracterizarían por la austeridad y sobriedad de líneas compositivas, desviándose posteriormente hacia una exaltación decorativista que lo alejaría de los planteamientos originales. Intentaremos para ello abordar cuales fueron las razones fundamentales de esa aparente desviación de la vida conventual en el ámbito occidental, que supuso un cambio en la esencia del propio proceso constructivo.
El trabajo social de las congregaciones religiosas en Andalucía: la protección a la infancia marginada
Authors: Montero Pedrera Ana Mª
Published: April 2024

El trabajo social desarrollado por las congregaciones andaluzas ha sido constante a lo largo de la historia. Cuando comienzan a aparecer normas legales para regular este tema los religiosos y religiosas habían creado una infraestructura que los gobiernos aprovecharon, sobre todo en lo que se refiere a la atención a la infancia y a la juventud. Así se va pasando de la caridad a la beneficencia, de la atención privada a la atención estatal. Desde finales del siglo XIX hubo un movimiento que propugnaba la protección a la infancia, concretamente de los menores delincuentes y del uso de unos métodos reeducativos propios. Nacen muchas congregaciones y una de ellas es la de los Terciarios Capuchinos de Nuestra Señora de los Dolores que funda Luis Amigó y que se extenderá por toda España con sus instituciones auxiliares de los Tribunales Tutelares de Menores. Donde aplicaron unmétodo reeducador propio, que fue seguido por otras instituciones de las mismas características de dentro y fuera de España y que ha perdurado casi un siglo.
La Sociedad Mozárabe
Authors: Gil Juan
Published: April 2024

Se estudian en este artículo los diversos estamentos de la sociedad mozárabe: la nobleza, rica y poderosa, influyente todavía en el siglo XI; la Iglesia, pujante a lo largo del emirato y del califato, si bien sometida al dictamen del amo musulmán; una burguesía consistente en funcionarios al servicio de los poderosos, pero también en médicos y mercaderes, amén de comerciantes que iban a vender sus géneros por toda Europa; y finalmente, una gran masa de desheredados: obreros en la ciudad y labriegos en el campo; en el estrato más bajo se encuentran los esclavos.
El antiguo Oratorio de San Felipe Neri en Córdoba: aproximación histórica y análisis artístico
Authors: Carmona Medeiro Elena
Published: April 2024

En el año 1696 el Cardenal Luis Belluga y Moncada llevó a cabo la fundación de la Congregación de San Felipe Neri en la ciudad de Córdoba. Para su establecimiento costeó la adquisición de un antiguo palacio perteneciente al mayorazgo de Luis Venegas de Henestrosa y mandó erigir en su interior una modesta iglesia cuya traza se atribuye a Hurtado Izquierdo. En 1835, con la exclaustración de los conventos regulares masculinos, el conjunto fue destinado a usos militares y sus obras de arte fueron confiscadas. El hallazgo de una documentación inédita hace posible una fiable reconstrucción del antiguo Oratorio de los filipenses y de sus bienes más preciados.
Es día de alegría grande. Celebraciones y fiestas religiosas en la Andalucía del Barroco
Authors: Escalera Pérez Reyes
Published: April 2024

Los pueblos y ciudades de Andalucía celebraron durante los siglos XVII y XVIII innumerables fiestas organizadas por los más  variados motivos, desde la subida al trono de un rey a la canonización de un santo. Aunque el principal promotor de ellas es el poder civil las celebraciones asociadas a la Iglesia eran también muy numerosas. Algunas de ellas eran de carácter anual como la Semana Santa, el Corpus Christi o las fiestas patronales, y otras extraordinarias u ocasionales, entre las que destacan las  beatificaciones y canonizaciones, consagraciones de iglesias, autos de fe, rogativas, acción de gracias, adquisición de reliquias y las dedicadas a la Inmaculada. Estos acontecimientos eran vividos con gran entusiasmo por la población que veía cómo sus calles se limpiaban y adornaban para acoger a las procesiones así como catedrales, iglesias y conventos transformaban su fisonomía gracias a las arquitecturas ficticias que se erigían en ellas, plenas de alegorías y jeroglíficos que las convertían en “arquitecturas parlantes”. En este artículo se repasan las manifestaciones festivas religiosas más significativas de esta época en Andalucía, destacando laimportancia del aparato efímero y el mensaje que transmitía a la población.
La función didáctica del arte barroco en Andalucía
Authors: Ravé Prieto Juan Luis
Published: April 2024

Una de las características más importantes del Barroco andaluz es su evidente función didáctica. A la vocación retórica y expresiva  de su versión europea se une una especial atención a los valores propios de la cultura andaluza, gusto por los contrastes entre lo popular y lo culto, naturalismo, interés por la efusión de la emotividad y de los sentimientos, siempre dentro de una cierta  contención y decoro. La imagen devocional debe atraer al espectador, conmoviéndolo y suscitando en él sentimientos de reflexión, arrepentimiento, para conducirlo hacia la conversión en consonancia con los textos de la nueva espiritualidad promovida por los escritores modernos como Ignacio de Loyola y muy pronto recogida por los tratadistas de arte del momento. El carácter globalizador del Barroco produjo conjuntos monumentales donde las Bellas Artes están al servicio de un mensaje unitario que se dota de un alto contenido teológico como es le caso del templo de San Luis de los franceses de Sevilla, imagen del templo de Salomón y de la Jerusalén celestial, sostenido por los pilares virtudes cristianas y ejemplo máximo de la continuidad entre el Antiguo y Nuevo Testamento, fruto de la coherencia espiritual y cultural que se produce en el Barroco.
Un movimiento seglar en el postconcilio almeriense: equipos de Cristo Amor Sembrarás (ECAS)
Authors: Escámez Mañas Francisco José
Published: April 2024

El joven sacerdote Jesús Peregrín, sin mayor atractivo humano pero con recia espiritualidad,  a mediados de los años sesenta del pasado siglo es encargado de la promoción vocacional en Almeria. Es el origen de un masivo apostolado con la juventud, de ambos sexos. Así, en plena turbulencia postconciliar, y a contrapelo de la confusión, germina y cristaliza el movimiento ECAS. Decenas de miles de jóvenes han tenido una experiencia de fe haciendo Ejercicios Espirituales. Con ese impulso han ocupado un puesto de servicio en la Iglesia. Primero se implicaron en el apoyo a las Misiones. Más tarde continúan la ayuda al Tercer Mundo mediante la Fundación Jesús Peregrín.
La archidiócesis de Sevilla a fines del Antiguo Régimen: apuntes sobre su organización económica y pastoral
Authors: Ladero Fernández Carlos L.
Published: April 2024

El siguiente trabajo desarrolla, de forma breve y concisa, la organización económica y pastoral del arzobispado de Sevilla en la segunda mitad del siglo XVIII. La escasez de estudios globales sobre la ordenación diocesana, que integren sus diferentes estructuras y desarrolle su terminología, fuerzan esta síntesis conceptual que pretende facilitar el acceso a aquellos que deseenadentrarse en los pormenores de la historia eclesiástica, siguiendo el ejemplo concreto de la sede hispalense. Desde la posesión del beneficio eclesiástico, se estudian los diferentes agentes que, al frente de un ministerio determinado, vertebran la estructura diocesana y la dotan de personalidad. A su vez, se pone en contraste la particular praxis organizativa del arzobispado de Sevilla en función del objetivo perseguido: pastoral o económico.

La música litúrgica y profana en los antiguos conventos: Fr. Gerónimo González y la Casa Grande del Carmen de Sevilla
Authors: Álvarez Calero Alberto J.
Published: April 2024

No se ha escrito demasiado sobre la práctica de música profana en los antiguos conventos, tanto dentro de las diversas celebraciones religiosas, como incluso en los momentos de esparcimiento. Tomando como fuentes primarias para ilustrar todo lo anterior, el articulista se centra después en un convento, la Casa Grande del Carmen de Sevilla, y en particular en un compositor que estuvo mucho tiempo allí a mediados del s. XVII: fr. Gerónimo González. A partir de su incompleta biografía, en estas páginas se reflexiona sobre el papel de los músicos religiosos más allá de su ámbito conventual, pues éste por ejemplo llegó a ser muy conocido sobre todo en la corte portuguesa del rey João IV.
La configuración parroquial de la Diócesis de Almería
Authors: Escámez Mañas Francisco José
Published: April 2024

La Iglesia Católica se estructura en diócesis o iglesias locales, porción del pueblo de Dios -territorio y población atendidos por un obispo-, que a su vez se subdividen en parroquias y otro tipo de comunidades, servidas por presbíteros. Más allá del simple dato administrativo, su relevancia radica en que los fieles católicos viven su inserción en la Iglesia en dichas instancias, de menor a  mayor, parroquia y diócesis. De las parroquias emana la mayor parte del potencial espiritual y humano que nutre la vida y misión de la Iglesia. El presente trabajo ofrece una aproximación al proceso que ha seguido la configuración parroquial en la actual  diócesis almeriense, enmarcado en la historia diocesana. Los grandes momentos que vertebran dicha configuración serán las  erecciones parroquiales inmediatas a la Reconquista -decretadas en 1501 y 1505, respectivamentepasando por el arreglo de 1900, con el momento culminante: la incorporación a la diócesis de los territorios provinciales encuadrados en las diócesis vecinas, en 1953 y 1957; hasta la última creación numerosa en 1973, sin olvidar las más recientes. La existencia y dinamismo de las  comunidades parroquiales moldean la pastoral y suponen un indudable influjo católico en la identidad provincial de la Almería Moderna y Contemporánea.
La Academia Hispalense de Santo Tomás de Aquino (1880-1884)
Authors: Ruiz Sánchez José-Leonardo
Published: April 2024

Al objeto de afrontar la situación del mundo resultante de la modernidad, fundamentada en principios contrarios a la Iglesia, León XIII (1878-1903) restauró los planteamientos filosóficos y teológicos del tomismo mediante la encíclica Aeterni Patris Filius (1880). Para difundirlos se fundaron por todo el mundo las Academias con el nombre del Doctor Angélico. En España se instalaron las de Barcelona y la de Sevilla, titulada Academia Hispalense de Santo Tomás de Aquino (1880-1884), de duración efímera.
