Rice HUSK silica: A review from conventional uses to new catalysts for advanced oxidation processes.

The rice industry is of great importance worldwide and within the cereal industrialization process, rice husk is obtained as waste, a by-product with various alternative uses, among others, the obtaining of amorphous silica, a covalent oxide with chemical, structural and textural properties suitable for use as catalytic support. This review shows the potential of rice husk silica in the synthesis of heterogeneous catalysts with transition metals for the oxidation of different polluting molecules present in water, as well as the limitations of the catalytic system and the way to overcome them through new synthesis routes, to obtain single atom catalysts - SACs. The main preparation strategies applied for aqueous phase systems are summarized, as well as the studies of single atom catalysts in oxidation reactions of recalcitrant compounds using silica as support and, finally, the perspectives and opportunities regarding this novel topic.

Relationship between Oral Lichen Planus and Cardiovascular Disease of Atherosclerotic Origin: Systematic Review and Meta-Analysis.

Background/Objectives: Oral lichen planus (OLP) is a chronic inflammatory autoimmune disease of the oral mucosa that affects between 0.5% and 2% of the general population. In the last decade, several studies have associated cardiovascular diseases (CVDs) with some inflammatory skin diseases such as oral lichen planus, demonstrating the presence of dyslipidemia in these pathologies. The objective of this work is to review whether patients with OLP show higher dyslipidemia and CRP levels compared to a healthy control population without OLP. Methods: Searches were carried out in Medline, Scopus, and Cochrane. The studies had to perform a histopathological diagnosis for OLP and the patients could not take any medication to treat this disorder. Non-lichenoid reactions were included. Results: After an initial search that provided us with 254 papers, this number was reduced to 10 articles after a detailed evaluation. All of them were case-control studies that compared the presence of analytical cardiovascular risk factors in patients affected by OLP and in healthy subjects. Conclusions: There is no scientific evidence of the possible association between OLP and CVDs. The only association we can prove is the one between OPL and CVD risk factors, especially those related to the lipid profile. More studies are needed in order to evaluate this relationship in patients diagnosed with CVDs.

Primary lateral sclerosis associated with PSEN1 Pro284Leu variant in a Colombian family: Clinical and neuropathological features.

INTRODUCTION: This study investigates primary lateral sclerosis (PLS) as a rare manifestation of the presenilin 1 (PSEN1) NM_000021 c.851C > T p.Pro284Leu variant in three siblings of a Colombian family, outlining its clinical and neuropathological features and their relationship to Alzheimer's disease (AD). METHODS: Data were gathered using clinical evaluations, next-generation genetic sequencing, magnetic resonance imaging, biomarker analysis, and neuropathological examination. RESULTS: Carriers of the PSEN1 Pro284Leu variant exhibited classic PLS symptoms, including unilateral onset and bulbar syndromes, along with cognitive decline. Neuropathology showed corticospinal tract degeneration without amyloid beta deposition in spinal white matter. DISCUSSION: Our findings suggest an overlap between PLS and AD pathology in PSEN1 variant carriers. Results support considering PLS when diagnosing AD-related motor syndromes and including PSEN1 evaluation when performing genetic testing for PLS. The study highlights the need for further research to clarify the PLS-AD relationship, informing future treatments and clinical trials. HIGHLIGHTS: Pathogenic variants in presenilin 1 (PSEN1) can manifest as hereditary primary lateral sclerosis PSEN1 Pro284Leu carriers present motor, cognitive, and behavioral alterations  Cases had corticospinal tract microgliosis and severe Aß pathology in motor cortex  There was no evidence of amyloid deposition in the spinal cord white matter  All the neuropathology images are available for online visualization  Myelin pallor in the spinal cord is confined to the lateral corticospinal tracts.

Influence of Schneiderian Membrane Perforation on Implant Survival Rate: Systematic Review and Meta-Analysis.

Background: Maxillary sinus lift is a well-documented and accepted technique in the rehabilitation of the posterior maxilla. Schneiderian membrane perforation is the most common complication and may occur in between 7% and 56% of cases. Different materials and techniques have been described to achieve reparation of the perforation. The aim of this study was to establish whether the perforation of the Schneiderian membrane and its repair during maxillary sinus lift surgery results in a lower implant survival rate compared to those cases where the membrane has not been perforated. Materials and methods: A systematic review and meta-analysis of studies assessing the survival rate of implants placed in regenerated sinus using the lateral window approach, where the perforation of the Schneiderian membrane occur, was carried out. Statistical analysis was performed with Open Meta-Analyst, calculating the odds ratio of implants placed in perforated sinuses and non-perforated sinuses. Results: Ten articles were included in the qualitative analysis and seven articles in the quantitative analysis or meta-analysis. A total of 1224 maxillary sinus augmentation surgeries were performed without perforation of the Schneiderian membrane and 2725 implants were placed; 62 implants failed during the follow-up period with an overall survival rate of 97.7%. In 480 perforated sinuses, 1044 implants were placed, of which 30 failed; the overall survival rate was 97.1%. There were no significant differences between the implant survival rate of the implants in the two groups (OR = 0.78; CI = 0.49-2.23; p = 0.28 and I2 heterogeneity: 0%, p = 0.44). Conclusions: Schneiderian membrane perforation, as long as it is repaired, does not appear to negatively influence implant survival rate. Membrane perforation should not be considered a reason to abort the procedure or an absolute contraindication to implant placement.

Parkinson's Disease Gene Screening in Familial Cases from Central and South America.

BACKGROUND: Parkinson's disease (PD) is the second most common neurodegenerative disease following Alzheimer's disease. Nearly 30 causative genes have been identified for PD and related disorders. However, most of these genes were identified in European-derived families, and little is known about their role in Latin American populations. OBJECTIVES: Our goal was to assess the spectrum and frequency of pathogenic variants in known PD genes in familial PD patients from Latin America. METHODS: We selected 335 PD patients with a family history of PD from the Latin American Research Consortium on the Genetics of PD. We capture-sequenced the coding regions of 26 genes related to neurodegenerative parkinsonism. Of the 335 PD patients, 324 had sufficient sequencing coverage to be analyzed. RESULTS: We identified pathogenic variants in 41 individuals (12.7%) in FBXO7, GCH1, LRRK2, PARK7, PINK1, PLA2G6, PRKN, SNCA, and TARDBP, GBA1 risk variants in 25 individuals (7.7%), and variants of uncertain significance in another 24 individuals (7.4%) in ATP13A2, ATP1A3, DNAJC13, DNAJC6, GBA1, LRKK2, PINK1, VPS13C, and VPS35. Of the 70 unique variants identified, 19 were more frequent in Latin Americans than in any other population. CONCLUSIONS: This is the first screening of known PD genes in a large cohort of patients with familial PD from Latin America. There were substantial differences in the spectrum of variants observed in comparison to previous findings from PD families of European origin. Our data provide further evidence that differences exist between the genetic architecture of PD in Latinos and European-derived populations. © 2024 The Author(s).

Role adoption, anxiety, depression and loneliness in family caregivers of patients with chronic diseases.

OBJECTIVE: to describe and explore the relationship of loneliness, anxiety and depression with adoption of the caregiver role among individuals caring for people with chronic diseases in Colombia. METHODS: this was an exploratory and cross-sectional study involving 960 primary caregivers of individuals with chronic diseases. We applied the Caregiver Role Adoption Scale, the University of California at Los Angeles Loneliness Scale, and the Anxiety and Depression Scale. Principal component and multiple correspondence analyses were performed for clustering. RESULTS: among the participating caregivers, 40.8% reported experiencing depression, 59% reported anxiety, 54.6% reported moderate to severe loneliness, and 88.6% reported satisfactory adoption of the caregiver role. Caregivers who presented basic or insufficient role adoption levels tended to have higher scores for anxiety, depression and loneliness. CONCLUSION: adoption of the caregiver role is a mediator in the anxiety, depression and loneliness levels among caregivers. Strategies aimed at supporting caregivers should include training for the caregiver role to mitigate the negative impacts of anxiety, depression and loneliness. (1) More than half of the caregivers reported moderate or severe anxiety and loneliness. (2) Caregivers with low role adoption levels presented more anxiety, depression and loneliness. (3) Satisfactory adoption of the caregiver role reduces anxiety, depression and loneliness. (4) Role adoption should be intervened to reduce the impact on caregivers' mental health.

Association of Connective Tissue Grafts in Immediate Implants: Systematic Review and Meta-Analysis.

BACKGROUND: The increase in soft tissue (ST) around implants can benefit peri-implant health and aesthetic results. The objective was to compare the gingival and esthetic health benefits of immediate implant placement (IIP) with simultaneous or delayed connective tissue graft (CTG) compared to IIP without CTG. METHODS: A systematic review was carried out by two reviewers in Medline-Pubmed, Scopus, and Cochrane. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were considered. Randomized Clinical Trials (RCTs) that were published between April 2017 and February 2024 were used. Studies that analyzed the performance of a simultaneous or deferred CTG after the placement of an implant in the aesthetic zone, with or without immediate provisionalization, without previous regeneration, with a follow-up of 6 months, and that were performed in humans were included. RESULTS: Quantitative analysis was performed using data provided by the RCTs. The five RCTs that were selected analyzed a total "n" of 245 subjects who met the inclusion criteria and focused on the subject of the study. In the quantitative analysis, four RCTs were included. The studies evaluated buccal gingiva levels when placing the IIP with and without CTG, obtaining a mean buccal gingiva level difference of 0.09 mm (95% CI: -0.54 to 0.72, p = 0.05), statistically not significant, but with a favorable trend. CONCLUSIONS: The use of CTG associated with the II can maintain the gum level but not increase the volume. CTG is favorable for achieving successful esthetic results when immediate placement of an implant with a provisional prosthesis is planned.

Comparative Analysis of Quality of Life of Family Caregivers of Patients With Heart Failure and Cancer Who Receive Palliative Care.

BACKGROUND: Quality of life (QoL) is the criterion-standard outcome in palliative care for patients with various illnesses and their family caregivers. There is a need to determine the factors affecting caregivers' QoL in each population and the differences between groups to design differentiated intervention strategies. PURPOSE: The aims of this study were to compare the role adoption, social support, and QoL of family caregivers of patients with heart failure and cancer in palliative care and to examine the determinants of QoL. METHODS: A comparative study was conducted with the family caregivers of patients with cancer (n = 81) and heart failure (n = 80) in palliative care. Quality of life in life-limiting situations, role adoption, and social support questionnaires were also administered. A χ2 test, Student t test, and Mann-Whitney U test were used for between-group comparisons. Multiple linear regression was used to examine the effects of the correlated variables on caregivers' QoL. RESULTS: Caregivers of patients with heart failure had better QoL (P = .006) and lower tangible social support (P = .007) than caregivers of patients with heart failure. No differences were found in caregiver role adoption between the groups. Linear regression indicated that for caregivers of patients with cancer, social support, role adoption, caregiver age, and patient functional status affect caregiver QoL. For caregivers of patients with heart failure, role adoption and patient functional status are predictors of QoL. CONCLUSIONS: Overall, healthcare professionals should focus on improving social support and caregiver role adoption and provide greater attention to the QoL of caregivers of patients with cancer.

The Accuracy of Bone Assessment Distal to Lower Second Molars Using Panoramic Radiography: A Systematic Review and Meta-Analysis.

Panoramic radiography (OPG) evaluates mandibular third molar impaction (MTMI). This systematic review aimed to investigate the diagnostic accuracy of OPG in detecting bone loss distal to the lower second molars. The associated bone loss with different impaction positions and the most prevalent positions of MTMI were investigated as secondary outcomes. In January 2023, PubMed, Scopus, and Cochrane were searched to identify studies published between January 2012 and January 2023. Two examiners blindly selected the eligible studies for data extraction and quality assessment. Of 427 studies, 8 were suitable for data extraction. All studies reported bone loss distal to the second molar using OPG, ranging from 4.9 to 62.9%. The most frequent position of MTMI is mesioangular. The distal bone loss in the vertical and horizontal positions is statistically significant compared to typically positioned third molars and those that are fully erupted or impacted, but in a normal orientation (p-value 0.005 and 0.02, respectively). Bone loss was not statistically significant in the mesioangular position compared to other impacted positions (p-value 0.14). The risk of bias ranges between 66 and 88%. Despite its limitations, OPG is still considered a valuable tool to assess bone loss distal to the lower second molar in cases of an impacted mandibular third molar.

Genetic modifiers of cognitive decline in PSEN1 E280A Alzheimer's disease.

INTRODUCTION: Rate of cognitive decline (RCD) in Alzheimer's disease (AD) determines the degree of impairment for patients and of burden for caretakers. We studied the association of RCD with genetic variants in AD. METHODS: RCD was evaluated in 62 familial AD (FAD) and 53 sporadic AD (SAD) cases, and analyzed by whole-exome sequencing for association with common exonic functional variants. Findings were validated in post mortem brain tissue. RESULTS: One hundred seventy-two gene variants in FAD, and 227 gene variants in SAD associated with RCD. In FAD, performance decline of the immediate recall of the Rey-Osterrieth figure test associated with 122 genetic variants. Olfactory receptor OR51B6 showed the highest number of associated variants. Its expression was detected in temporal cortex neurons. DISCUSSION: Impaired olfactory function has been associated with cognitive impairment in AD. Genetic variants in these or other genes could help to identify risk of faster memory decline in FAD and SAD patients.

Mandibular Third Molar Impaction and Bone Change Distal to the Second Molar: A Panoramic Radiographic Study.

Background: The mandibular third molar is the most frequently impacted tooth. An impacted mandibular third molar (IMTM) can have negative consequences on the adjacent mandibular second molar (MSM), such as bone loss. An IMTM can be identified using orthopantomography (OPG). Our objective is to compare changes in bone level distal to the mandibular second molar (MSM) in patients with an extracted IMTM versus non-extracted IMTM using OPG. Methods: In this retrospective case-control study, 160 orthopantomograms (OPGs) of 80 patients who attended Dental Hospital of the University of Barcelona (HOUB) were randomly selected. Participants were stratified into a study group and control group. Results: Males and females experienced bone gain in the study group and bone loss in the control group. However, the difference in bone-level change was not statistically significant regarding gender in the study group. Within the study group, the age group of 29-39 years demonstrated significant (p-value = 0.042) bone gain after extraction compared to other age groups. However, the control group demonstrated bone loss in all age groups in which the difference is not statistically significant (p-value 0.794). Conclusions: Bone improvements distal to the MSM were observed after the extraction of an IMTM compared to when an IMTM was not extracted.

Terpyridine isomerism as a tool for tuning red-to-NIR emissive properties in heteronuclear gold(I)-thallium(I) complexes.

The polymeric linear chain [AuTl(C6Cl5)2]n reacts with three terpyridine-type ligands substituted with thiophene groups containing N-donor centres in different relative positions (L1, L2 and L3), leading to the Au(I)/Tl(I) complexes [AuTl(C6Cl5)2(L1)]n (1), [{AuTl(C6Cl5)2}2(L2)]n (2) and [AuTl(C6Cl5)2(L3)]n (3). X-Ray diffraction studies reveal that L1 acts as a chelate, while L2 and L3 act as bridging ligands, resulting in different coordination indexes for the thallium(I) centre. These structural differences strongly influence their optical properties, and while compounds 2 and 3 emit near the limit of the visible range, complex 1 emits in the infrared region. DFT calculations have also been carried out in order to determine the origin of the electronic transitions responsible for their optical properties.

Implementation of a coaching training for enhancing empathy and emotional intelligence skills in health science students: a prospective study.

BACKGROUND: Empathy and emotional intelligence are core competencies in the educational curriculum of health science students, both play a significant role in teamwork relationships and in attention patient's cares; so innovative strategies to enhance these emotional skills are required. We prospectively tested an academic coaching program for improving empathy and emotional intelligence in students of health sciences degrees. METHODS: A prospectively single arm intervention study was performed in undergraduate students of nursing, physiotherapy and occupational therapy of the Faculty of Health Sciences from the University of Granada (Spain). The three groups of students participated in nine sessions of coaching, which included a training program to manage patient's priorities and communication, adherence to treatment, motivation and satisfaction. Survey data included the Cognitive and Affective Empathy Test (TECA), the Trait Meta-Mood Scale (TMMS-24) and the Interpersonal Reactivity Index (IRI) which were assessed at baseline and post-intervention. RESULTS: A total of 93 students of 259 (mean age of 21.6 ± 3.2 years) participated in the study and completed the sessions of coaching/surveys. After the intervention, we observed an improvement in the cognitive dimension of empathy among nursing students (p = 0.035) and in the affective dimension of empathy in physiotherapy students (p = 0.044). In addition, an increase on perceived emotional intelligence among students was achieved only in nursing/physiotherapy groups (p ≤ 0.048). Finally, slight improvements were founded in the dimensions "Perspective-Taking" and "Personal Distress" of the occupational therapy group (p ≤ 0.031). No significant differences were found for the rest of variables of TECA (p ≥ 0.052), TMMS-24 (p ≥ 0.06) and IRI (p ≥ 0.12). CONCLUSIONS: This study shows that an academic coaching intervention with students from health sciences degrees improves their empathy skills and self-perceived emotional intelligence. The current findings can be used to determine more effective approaches to implementing academic coaching interventions based in better designs as clinical trial studies.

Método: trata-se de um estudo exploratório e transversal que envolveu 960 cuidadores primários de indivíduos com doenças crônicas. Foi aplicada a Escala de Adoção do Papel de Cuidador, a Escala de Solidão da Universidade da Califórnia em Los Angeles e a Escala de Ansiedade e Depressão. Foram realizadas análises de componentes principais e de correspondência múltipla para o agrupamento. Resultados: entre os cuidadores participantes, 40,8% relataram ter depressão, 59% relataram ansiedade, 54,6% relataram solidão moderada a grave e 88,6% relataram uma adoção satisfatória do papel de cuidador. Os cuidadores que apresentaram níveis básicos ou insuficientes de adoção do papel tenderam a ter pontuações mais elevadas de ansiedade, depressão e solidão. Conclusão: a adoção do papel de cuidador é um mediador nos níveis de ansiedade, depressão e solidão entre os cuidadores. As estratégias destinadas a apoiar os cuidadores devem incluir o treinamento para o papel de cuidador, a fim de atenuar os impactos negativos da ansiedade, da depressão e da solidão.

Soledad, ansiedad, depresión y adopción del rol del cuidador de personas con enfermedad crónica en San Gil, Colombia

Introducción: Los cuidadores de personas con enfermedad crónica adoptan un nuevo rol que puede implicar respuestas como ansiedad, depresión y soledad. Objetivo: Describir y correlacionar las variables de adopción del rol del cuidador, depresión, ansiedad y soledad en cuidadores familiares de personas con enfermedad crónica en la provincia de Guanentina, en San Gil, Santander (Colombia), durante el año 2021. Método: Estudio descriptivo, analítico de corte transversal realizado con 112 cuidadores familiares de personas con enfermedades crónicas. Se utilizó una ficha de caracterización y los instrumentos: Escala adopción del rol del cuidador ROL, escala de soledad de UCLA (University of California at Los Ángeles) y Escala Hospitalaria de Ansiedad y Depresión HADS. Resultados: El perfil de los cuidadores fue predominantemente mujer; de 49 años en promedio; casadas, solteras o en unión libre; grado máximo de escolaridad bachiller; de ocupación hogar y nivel socioeconómico medio bajo y bajo. Se encontraron niveles altos de ansiedad en el 18,3 % de ellas, depresión en el 4,3 % y soledad en el 0,9 %, además, se evidenciaron niveles de adopción del rol del cuidador satisfactorios en el 100 %. Se encontró una correlación débil entre ansiedad, depresión y soledad y una correlación inversa entre estas variables con la adopción del rol del cuidador. De igual manera, se encontró una correlación directa entre la edad del paciente y los meses de diagnóstico con las horas de cuidado al día. Por último, se halló carácter predictivo de la ansiedad y la depresión sobre la adopción del rol, de la ansiedad y la adopción del rol sobre la depresión, y de la soledad y la depresión sobre la ansiedad. Conclusiones: los cuidadores tenían niveles de ansiedad, depresión y soledad normales que, al correlacionarse entre sí y con la adopción del rol del cuidador, validan la idea de que, si se interviene a los cuidadores en su trayectoria con orientaciones sobre su rol en cuanto a las labores, la organización y las respuestas se puede contribuir en la disminución de la ansiedad, depresión y soledad. Discusión: la correlación directa observada entre la soledad, depresión y ansiedad es coherente con lo reportado en estudios previos con cuidadores. Acorde con lo reportado por la literatura el desempeño satisfactorio del rol facilita los desenlaces en los cuidadores, en este caso, la moderación de la ansiedad, depresión y soledad.

Introduction: Caregivers of people with chronic disease adopt a new role that may involve responses such as anxiety, depression, and loneliness. Objective: To describe and correlate the variables of adoption of the role of caregiver, depression, anxiety and loneliness in family caregivers of people with chronic disease in the Guanentina province in San Gil, Santander (Colombia), during the year 2021. Methods: Descriptive study, cross-sectional analysis carried out with 112 family caregivers of people with chronic diseases. A characterization sheet and the ROL, UCLA and HADS instruments were used. Results: the profile of the caregivers was predominantly female and average age of 49 years; married, single or in civil union; maximum degree of high school education; of household occupation and low and low-middle socioeconomic level. High levels of anxiety were found in 18,3% of them, depression in 4,3% and loneliness in 0,9%, in addition, satisfactory levels of adoption of the caregiver role were evidenced in 100%. A weak correlation was found between anxiety, depression and loneliness and an inverse correlation between these variables with the adoption of the caregiver role. Similarly, a direct correlation was found between the patient's age and the months of diagnosis with the hours of care per day. Finally, anxiety and depression were found to be predictive of role adoption, of anxiety and role adoption on depression, and of loneliness and depression on anxiety. Conclusions: the caregivers had normal levels of anxiety, depression and loneliness that, when correlated with each other and with the adoption of the caregiver role, validate the idea that, if caregivers are intervened in their trajectory with guidance on their role in terms of the tasks, the organization and the answers can contribute in the reduction of anxiety, depression and loneliness. Discussion: The direct connection observed between loneliness, depression and anxiety is consistent with what has been reported in previous studies with caregivers. In accordance with what has been reported in the literature, satisfactory performance of the role facilitates the outcomes in caregivers, in this case, the moderation of anxiety, depression and loneliness.

PALLIATIVE CARE AND END OF LIFE CARE IN LATIN AMERICA: SCOPING REVIEW

INTRODUCTION: Populational aging and improved treatments for chronic non-communicable diseases extend life expectancy but not always quality of life. By 2060, 48 million people are expected to die of serious illnesses, and 83% of these deaths will occur in developing countries. Only 14% of those who needed palliative care receive it. AIM: To describe the methodological trends, thematic areas, populations studied, and future challenges in Latin American regions with respect to adult palliative care. METHODS: A scoping review of 60 articles from 2010 to 2019 in indexed journals in English, Spanish, and Portuguese was conducted. RESULTS: Most articles were from Brazil, Colombia, and Mexico. Patients, caregivers, healthcare professionals, and students constituted the primary study population. Quality of Life, knowledge, and costs of attention were also assessed. It appears that early palliative care improves the outcomes of patients, caregivers, and health care professionals, however, the disparity in palliative care services between Latin America, US, UK, Canada, and Spain is concerning. CONCLUSIONS: Globally, more palliative care is needed, especially in Latin America. However, there are not enough graduate palliative care programs. Academic palliative care education must be promoted. Communication between the interdisciplinary team, the patient, and the caregiver is critical. While the region's scientific literature output has improved, many knowledge gaps remain. For patients' sake, governments should regulate, create, and facilitate palliative care services.
