Selective serotonin reuptake inhibitors as a risk factor for dental implant failure: a retrospective clinical study.

The trend in recent decades in Europe and the United States points to an exponential increase in the consumption of antidepressant drugs and, in particular, selective serotonin reuptake inhibitors (SSRIs). This retrospective study aimed to investigate whether there is an association between SSRI intake and dental implant (DI) failure or survival and, secondarily, to investigate the influence of other systemic and local factors. This retrospective cohort study was done in accordance with the the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines for observational studies. A total of 170 patients received 573 DIs between 2014 and 2020.The reported DI failure rate was 6.11% (n = 35 DIs). Of these 18.31% failed in patients treated with SSRIs while 4.38% failed in patients who were not prescribed SSRIs (p < 0.001). Specifically, use of these drugs was associated with a hazard ratio rate of DI failure that was 4.53 times higher (95% CI: 1.93 to 10.61), and in the multivariate analysis, a 3.70 times higher adjusted risk was found. A lower DI survival rate at 90 months' follow up was also observed in these patients compared with those not taking them (84.30% vs 96%, respectively; p = 0.00014). With the limitations of the present study it can be affirmed that there is a relation between the intake of SSRIs and DI failure, as well as a lower survival rate in these patients.

Examining Facilitators and Barriers to Cardiac Rehabilitation Adherence in a Low-Resource Setting in Latin America from Multiple Perspectives.

Cardiac rehabilitation (CR) is under-used, particularly in low-resource settings. There are few studies of barriers and facilitators to CR adherence in these settings, particularly considering multiple perspectives. In this multiple-method study, a cross-sectional survey including the Cardiac Rehabilitation Barriers Scale (each item scored on a five-point Likert scale) was administered to patients treated between February and July, 2019, in three CR centers in Colombia. A random subsample of 50 participants was invited to a focus group, along with an accompanying relative. Physiotherapists from the programs were invited to an interview, with a similar interview guide. Audio-recordings were transcribed and analyzed using interpretive description. A total of 210 patients completed the survey, and 9 patients, together with 3 of their relatives and 3 physiotherapists, were interviewed. The greatest barriers identified were costs (mean = 2.8 ± 1.6), distance (2.6 ± 1.6) and transportation (2.5 ± 1.6); the logistical subscale was highest. Six themes were identified, pertaining to well-being, life roles, weather, financial factors, healthcare professionals and health system factors. The main facilitators were encouragement from physiotherapists, relatives and other patients. The development of hybrid programs where patients transition from supervised to unsupervised sessions when appropriate should be considered, if health insurers were to reimburse them. Programs should consider the implications regarding policies of family inclusion.

Azo dye biotransformation mediated by AQS immobilized on activated carbon cloth in the presence of microbial inhibitors.

In this work, anthraquinone-2-sulfonate (AQS) was covalently immobilized onto activated carbon cloth (ACC), to be used as redox mediator for the reductive decolorization of reactive red 2 (RR2) by an anaerobic consortium. The immobilization of AQS improved the capacity of ACC to transfer electrons, evidenced by an increment of 3.29-fold in the extent of RR2 decolorization in absence of inhibitors, compared to incubations lacking AQS. Experiments conducted in the presence of vancomycin, an inhibitor of acidogenic bacteria, and with 2-bromoethane sulfonic acid (BES), an inhibitor of methanogenic archaea, revealed that acidogenic bacteria are the main responsible for RR2 biotransformation mediated by immobilized AQS. Nonetheless, the results also suggest that some methanogens are able to maintain their capacity to use immobilized AQS as an electron acceptor to sustain the decolorization process, even in the presence of BES.

La protección de los derechos de autor, a la luz del procedimiento especial abreviado y la figura del acusador privado (Ley 1826) en el Derecho penal colombiano / Copyright protection, in the light of the special abbreviated procedure and the private prosecutor figure (Law 1826) in the Colombian Criminal Law / A proteção dos direitos de autor, à luz do procedimento especial abreviado e a figura do acusador privado (Lei 1826) no Direito penal colombiano

Resumen Con este artículo se pretende analizar las repercusiones de la Ley 1826 de 2017 -del procedimiento especial abreviado y de la figura del acusador privado- cuando de delitos no querellables se trata, usando como ejemplo el delito a la violación de los derechos patrimoniales de autor para demostrar, a través de la dogmática jurídica, que el empleo del poder punitivo estatal, en muchos casos, no cumple su finalidad de sancionar solo aquellas conductas particularmente lesivas para los bienes jurídicos, situación que puede terminar beneficiando a titulares de los derechos de autor con poder en el mercado, así la afectación sea mínima. Es así como se concluye que es necesario excluir los delitos que atenten contra los derechos patrimoniales de autor de tramitarse por el procedimiento especial abreviado y del acusador privado para cumplir con los fines del poder punitivo estatal.

Abstract This paper aims to analyze the impact of Law 1826/2017 -of the special abbreviated procedure and the private prosecutor figure- in the case of non-criminal complaints, using as an example the crime of violation against property rights of the author to demonstrate through the legal dogmatic, that in most cases, the use of the punitive power of the state does not accomplish its purpose of sanctioning only those conducts that are particularly detrimental to the legal assets. This circumstance can result benefiting copyright holders with power in the market, even if the affectation might be minimal. Thus, it concludes that it is necessary to exclude crimes that infringe on the author's property rights in case of processing by the special abbreviated procedure and the private prosecutor figure to accomplish the goals of the state's punitive power.

Resumo Com o presente artigo pretende-se analisar as repercussões da Lei 1826 de 2017 - do procedimento especial abreviado e da figura do acusador privado - quando se trata de delitos no querellables, usando como exemplo o delito à violação dos direitos patrimoniais de autor para demonstrar, por meio da dogmática jurídica, que o uso do poder punitivo estatal, em muitos casos, não cumpre sua finalidade de sancionar só aquelas condutas particularmente lesivas para os bens jurídicos, situação que pode terminar beneficiando aos titulares dos direitos autorais com poder no mercado, embora a afetação seja mínima. É assim como se conclui que é necessário excluir os delitos que atentem contra os direitos patrimoniais de autor no caso de serem tramitados pelo procedimento especial abreviado e do acusador privado para atingir os propósitos do poder punitivo estatal.

Pathogenesis of Drug Induced Non-Allergic Angioedema: A Review of Unusual Etiologies.

Angioedema is the swelling of mucosal and sub-mucosal tissue. Typically, it manifests as the swelling of the face, lips, and tongue. Angioedema can be severe and life threatening when it involves the respiratory tract. Drug induced allergic angioedema and drug induced non-allergic angioedema differ in their mediator, their clinical presentations, and their management. In drug induced non-allergic angioedema, symptoms are resistant to antihistamine and corticosteroid treatment. The aim of the analysis was to identify which medications are associated with drug-induced non-allergic angioedema and to understand the mechanism of action via which of these medication cause angioedema.

Objetivos: identificar, mediante la técnica de reacción en cadena de la polimerasa, diez especies bacterianas procedentes de conductos radiculares necróticos, así como analizar su asociación con signos y síntomas de la periodontitis apical (dolor, exudado y movilidad), dentro de un área geográfica específica, Santiago de Compostela (noroeste de España). Métodos: se realizó un estudio descriptivo, en un plazo de recogida de muestras de un año. Se extrajeron 43 muestras de los conductos radiculares necróticos, a razón de una muestra por pacientes, quienes fueron examinados previamente para determinar la presencia de periodontitis apical radiográfica, de la cual fueron descritos sus signos y síntomas. Se utilizaron puntas de papel absorbentes estériles y se procedió a extraer de dichas muestras el ADN por medio de la técnica del fenol-cloroformo. El producto se amplificó por medio de la reacción en cadena de la polimerasa, usando cebadores específicos para diez microorganismos. El resultado se visualizó por medio de electroforesis, utilizando un transiluminador UV. Los resultados se analizaron estadísticamente, para así establecer qué microorganismos estaban presentes de forma individual y cuáles se presentaron formando asociaciones como el llamado red complex, en relación con los signos y síntomas presentes en la periodontitis apical. Resultados: Fusobacterium nucleatum fue el microorganismo con presencia de forma individual más frecuente (83,72 por ciento de las muestras). En cuanto al estudio de la asociación de los microorganismos con los signos y síntomas, Porphyromonas endodontalis presentó una asociación significativa con respecto al exudado (p< 0,05) y movilidad (p< 0,05). En cambio, Enterococcus spp. y Treponema denticola (p< 0,01) presentaron ambos una asociación significativa con respecto al dolor. En cuanto a la incidencia del red complex fue de 6 casos en total. Conclusiones: Fusobacterium nucleatum y Streptococcus spp. son los microorganismos identificados con mayor porcentaje en comparación a los restantes estudiados. Porphyromonas endodontalis es el microorganismo con mayor asociación estadística con respecto a los signos y síntomas de la periodontitis apical(AU)

Objectives: identify by polymerase chain reaction technique ten bacterial species obtained from necrotic root canals, and analyze their association with signs and symptoms of apical periodontitis (pain, exudate and mobility) in a specific geographic area: Santiago de Compostela (northwestern Spain). Methods: a descriptive study was conducted based on a one-year sample collection period. Forty-three samples were taken from necrotic root canals, at a rate of one sample per patient, who had been previously examined for radiographic apical periodontitis, of which the signs and symptoms were described. Sterile absorbent paper points were used to extract the DNA samples, applying the phenol-chloroform technique. The product was amplified by polymerase chain reaction, using specific primers for ten microorganisms. The result was visualized by electrophoresis using a UV transilluminator. Outcomes were analyzed statistically to determine which microorganisms were present individually and which formed associations such as the so-called red complex, according to the signs and symptoms present in the apical periodontitis. Results: Fusobacterium nucleatum was the most common individual microorganism (83.72 percent of the samples). As to the association of microorganisms with signs and symptoms, Porphyromonas endodontalis was found to be significantly associated with exudate (p< 0.05) and mobility (p< 0.05), while both Enterococcus spp. and Treponema denticola (p< 0.01) had a significant association with pain. Incidence of the red complex was 6 cases in all. Conclusions: Fusobacterium nucleatum and Streptococcus spp. were the microorganisms identified as displaying the highest percentages. Porphyromonas endodontalis showed the greatest statistical association with signs and symptoms of apical periodontitis(AU)

An Unusual Case of Acute Chondrocalcinosis in Wrist Joint Presenting as Cellulitis.

Chondrocalcinosis is a common arthritic disorder among elderly patients. We present a case of a 71-year-old woman presenting with an acute episode of the left forearm with hand swelling. A provisional diagnosis of cellulitis was made and the patient was started on intravenous antibiotics. The patient's condition did not improve. Joint aspiration of the wrist joint was done and showed positive birefringent rhomboid-shaped crystals. A final diagnosis of acute chondrocalcinosis was made.

Hand2 inhibits kidney specification while promoting vein formation within the posterior mesoderm.

Proper organogenesis depends upon defining the precise dimensions of organ progenitor territories. Kidney progenitors originate within the intermediate mesoderm (IM), but the pathways that set the boundaries of the IM are poorly understood. Here, we show that the bHLH transcription factor Hand2 limits the size of the embryonic kidney by restricting IM dimensions. The IM is expanded in zebrafish hand2 mutants and is diminished when hand2 is overexpressed. Within the posterior mesoderm, hand2 is expressed laterally adjacent to the IM. Venous progenitors arise between these two territories, and hand2 promotes venous development while inhibiting IM formation at this interface. Furthermore, hand2 and the co-expressed zinc-finger transcription factor osr1 have functionally antagonistic influences on kidney development. Together, our data suggest that hand2 functions in opposition to osr1 to balance the formation of kidney and vein progenitors by regulating cell fate decisions at the lateral boundary of the IM.

Membrane-mediated neuroprotection by curcumin from amyloid-ß-peptide-induced toxicity.

Amyloid-ß peptide (Aß)-membrane interactions have been implicated in the formation of toxic oligomers that permeabilize membranes, allowing an influx of calcium ions and triggering cell death in the pathogenesis of Alzheimer's disease (AD). Curcumin, a small dietary polyphenolic molecule, has been shown to reduce Aß-induced toxicity and AD pathology. We investigate here the effect of curcumin on Aß40-induced toxicity in cultured human neuroblastoma SH-SY5Y cells and test a novel neuroprotection mechanism in which curcumin reduces Aß-membrane interactions and attenuates Aß-induced membrane disruptions. Predominantly monomeric Aß40 exerts toxicity toward SH-SY5Y cells and has been shown to insert spontaneously into anionic lipid monolayers at the air/water interface, resulting in the misfolding and assembly of Aß into ß-sheet-enriched oligomers. Concomitantly, membrane morphology and lipid packing are disrupted. Curcumin dose-dependently ameliorates Aß-induced neurotoxicity and reduces either the rate or extent of Aß insertion into anionic lipid monolayers. Moreover, curcumin reduces Aß-induced dye leakage from lipid-bilayer-covered, dye-loaded, porous silica microspheres. Because curcumin neither affects the inherent surface activity of Aß nor modifies the membrane properties, it reduces Aß insertion by directly attenuating Aß-membrane interactions and reducing Aß-induced membrane disruption. Although the exact molecular mechanism of curcumin's membrane protective effect remains unclear, this effect could in part contribute to curcumin's neuroprotective effect with respect to Aß-induced toxicity. Our work reveals a novel molecular mechanism by which curcumin reduces Aß-related pathology and toxicity and suggests a therapeutic strategy for preventing or treating AD by targeting the inhibition of Aß-induced membrane disruption.

Capacidad respiratoria, niveles de vitamina C y malonilaldehído en estudiantes de bioanálisis fumadores y no fumadores / Respiratory capacity, vitamin C and malonilaldehyde levels in smokers and non smokers students of bioanalysis

Diversos autores señalan las implicaciones de fumar en la alteración de la capacidad respiratoria y del sistema oxida ción/an - tioxidación y la importancia de la detección de las mismas para contribuir en la prevención de diversas patologías. La presente investigación plantea evaluar la capacidad respiratoria y los niveles de vitamina C (VC) y malonilaldehído (MDA) de fumadores y no fumadores. Participaron 50 estudiantes de Bioanálisis de ambos sexos, clasificados según la Organización Mundial de la Salud en fumadores diarios (FD), fumadores ocasionales (FO) y no fumadores (NF). Los parámetros evaluados fueron: volumen espiratorio forzado en el primer segundo (VEF1) y la capacidad vital forzada (CVF), niveles de VC y MDA. Los resultados presentados como X +/- DS y porcentajes y analizados por ANOVA, fueron: El 69,2% y 84,6% de los estudiantes (FD, FO) presentaron valores normales de CVF y VEF, sin diferencias estadísticamente significativas con los NF. Los niveles de VC (mg/dl.) fueron 1,19 ± 0,30 (NF) con 1,12 ± 0,09 (FO) sin diferencias significativas entre ellos y el MDA (µm/l) mostró un aumento estadísticamente significativo (p < 0,05) en los F.O. (1,56 ± 0,5) con respecto a los NF (0,99 ± 0,60). Se concluye que los valores de MDA mostraron un aumento significativo en los FO, que se corresponden con manifestaciones de estrés oxidativo. Sin embargo, los niveles de vitamina C, aunque se mostraron más bajos en el grupo FO, no evidenciaron diferencias significativas al igual que los índices espirométricos.

Several authors have shown the implications of smoking in the alteration of respiratory capacity and oxidation / antioxidation system and the importance of screening them for help in preventing various diseases. In the present investigation was to assess respiratory capacity and vitamin C (VC) and malondialdehyde (MDA) levels of smokers and non smokers. Partici - pated 50 bioanalysis students both sexes, classified by the World Health Organization in daily smokers (DF), occasional smokers (OF) and non-smokers (NF). The evaluated parameters were: forced expiratory volume in first second (FEV1) and forced vital capacity (FVC), levels of VC and malonilaldehyde. Results presented as X ± SD and percentages and statistically analyzed by ANOVA, were 69,2% and 84,6% of students (DF, OF) had normal values of FVC and FEV, respectively, without differences significant height. VC levels (mg/dl) Were 1.19 ± 0.30 (NF) with 1.12 ± 0.09 (OF) without significant differences between them and the MDA (ìm/l) showed a statistically significant increase (p<0.05) their values in OF (1.56 ± 0.5) with res pect to NF (0.99 ± 0.60). We conclude that the values of MDA showed a significant increase in OF, which correspond to manifestations of oxidative stress. However, vitamin C levels, though were lower in FO group, showed no significant differences as well as spirometry.
