Antifibrotic treatment adherence, efficacy and outcomes for patients with idiopathic pulmonary fibrosis in Spain: a real-world evidence study.

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a rare disorder associated with increased mortality and morbidity. There are currently two drugs approved for IPF but their safety and efficacy profile in real-world settings in Spain is not well understood. METHODS: An observational, multicentre, prospective study was carried out among patients with IPF who started treatment with pirfenidone or nintedanib from 2015 to 2021. Data regarding clinical characteristics, drug adherence, safety profiles and clinical outcomes between these two drugs were collected. RESULTS: 232 patients were included in the analysis. There were no meaningful differences between both groups at baseline. Patients who started pirfenidone showed a decreased risk for treatment withdrawal compared with those starting nintedanib (HR 0.65 (95% CI 0.46 to 0.94; p=0.002)). Time to first adverse event and all-cause mortality was similar between study groups. Risk factors for withdrawal were female sex, diarrhoea and photosensitivity. CONCLUSIONS: in this real-world study, both pirfenidone and nintedanib showed similar efficacy profiles. Pirfenidone was associated with less treatment discontinuations due to side effects.

A 39-Year-Old Woman with Endometriosis Who Developed a Subcapsular Liver Hematoma Following Laparotomic Surgical Left Adnexectomy, Rectosigmoid Anastomosis, and Bilateral Ureteral Reimplantation.

BACKGROUND Endometriosis is a chronic inflammatory disease caused by endometrial tissue that grows outside the uterus. Deep endometriosis surgery is associated with considerable rates of complications, although such rates are lower in surgical procedures carried out by expert surgical teams. This report details a case of a rare but life-threatening complication in the postoperative period following 72 h of endometriosis surgery: a giant subcapsular hepatic hematoma, which was successfully managed conservatively. CASE REPORT Here we describe the case of a 39-year-old woman with deep endometriosis with ureteral, ovarian, and intestinal involvement requiring multidisciplinary surgery. She presented with severe anemia, respiratory distress, and oliguria 72 h postoperatively. A 3-phase computed tomography (CT) scan revealed a giant intrahepatic subcapsular hematoma (180×165×50 mm) lateral to the right hepatic lobe, which was managed conservatively. The patient evolved favorably and the hematoma was reduced (77×16 mm) in a follow-up CT scan performed 5 months later. CONCLUSIONS Giant liver hematoma is a rare, life-threatening complication. The current experience relating to its management remains largely limited owing to the rarity of the condition and paucity of published cases. Actually, we found no articles on hepatic hematoma in the context of endometriosis surgery. Early diagnosis and treatment are essential to reduce the patient's risk of death. Imaging diagnosis plays an essential role.

Role of hysteroscopy during conservative management of atypical endometrial hyperplasia and early-stage endometrial cancer in patients who desire pregnancy.

Twenty-five percent of cases of endometrial cancer appear in women with unfulfilled reproductive desires. An adequate selection of patients and a close hysteroscopic follow-up to monitor the endometrial response to the levonorgestrel-releasing intrauterine system (LNG-IUS) may be a valid and safe option for these patients. This is a case series and review of the literature study. We included eight patients diagnosed of complex endometrial hyperplasia with atypia (CEHA) or stage 1AG1 well-differentiated endometrial cancer without myometrial invasion who desired to get pregnant and opted for a conservative treatment. Follow-up was performed with hysteroscopy and directed biopsy at 3, 6 and 12 months. Of the 854 cases of complex endometrial hyperplasia with atypia (CEHA)/endometrial cancer were diagnosed, 2.3% were candidates for conservative management. We obtained a favourable regression of 71.2% at 6 months and 57% at one year with hormonal treatment. Conservative treatment in complex endometrial hyperplasia with atypia (CEHA)/low-grade endometrial cancer in reproductive age patients with a strong desire for pregnancy is feasible.

Micro-computed Tomographic Assessment and Comparative Study of the Shaping Ability of 6 Nickel-Titanium Files: An In Vitro Study.

INTRODUCTION: This research studies and compares the shaping ability of WaveOne Gold (WG; Dentsply Tulsa Dental Specialties, Tulsa, OK), the Reciproc Blue (RB; VDW, Munich, Germany), TRUShape (TS, Dentsply Tulsa Dental Specialties), XP-endo Shaper (XP; FKG, La Chaux-de-Fonds, Switzerland), iRace (IR, FKG), and TruNatomy (TN; Dentsply Sirona, Ballaigues, Switzerland) in the preparation of moderately curved canals and using micro-computed tomographic technology. METHODS: Sixty lower molars with 2 mesial canals were randomly distributed into 6 groups of 10 molars and 20 canals per group (n = 20). Specimens were scanned before and after preparation using the SkyScan 1275 (Bruker microCT, Kontich, Belgium). Group 1 was treated with WG, group 2 with RB, group 3 with TS, group 4 with XP, group 5 with IR, and group 6 with TN. After instrumentation, researchers quantified the changes produced in the canal geometry in terms of surface, volume, structure thickness, surface convexity index, structure model index, percentage of surface touched, and centroids. Wilcoxon and analysis of variance tests were performed to compare the values before and after preparation and the differences between groups. The significance level was established at 5%. RESULTS: There were no significant differences between WG and RB (P > .05) and between TN and XP (P > .05). TN had significant differences with WG, RB, TS, and IR (P < .05). All the files produced similar apical transportation (P > .05). CONCLUSIONS: WG and RB and TN and XP had similar shaping effectivity. TS and WG touched the highest percentages of canal surfaces (81% and 73%, respectively) but produced the biggest changes in the canal anatomy. TN and XP better kept the canal anatomy, but TN touched the lowest percentage of canal surface (50%). All the files used were able to clean and to shape moderately curved canals with minimal apical transportation.

TRUShape Versus XP-endo Shaper: A Micro-computed Tomographic Assessment and Comparative Study of the Shaping Ability-An In Vitro Study.

INTRODUCTION: The aim of this study was to evaluate and compare the shaping ability of XP-endo Shaper (XP; FKG Dentaire, La Chaux-de-Fonds, Switzerland) and TRUShape (TS; Dentsply/Tulsa Dental Specialties, Tulsa, OK) during the preparation of moderated curved root canals using micro-computed tomographic imaging. METHODS: Twenty human maxillary premolars with 2 roots were randomly separated into 2 groups of 10 teeth, which were scanned before and after root canal preparation using the SkyScan 1275 X-ray microtomograph (Bruker micro-CT, Kontich, Belgium) at a nominal resolution of <4 µm. Premolars and irrigant were maintained at 37° before and during preparation; group 1 was treated using XP and group 2 with TS. After preparation, researchers measured the amount of dentin removed, untreated superficies of canal walls, root canal volume, degree of canal transportation, and centering ability. Values of central tendency and dispersion were calculated using Statgraphics Centurion XV software (StatPoint Technologies, Inc, Warrenton, VA); means and median were compared using the Mann-Whitney-Wilcoxon test. The level of significance was set at 5% (P < .05). RESULTS: No significant statistical differences were observed between the 2 groups in shaping ability, untreated superficies of canal walls, degree of canal transportation, and centering ability (P > .05). CONCLUSIONS: Instrumentation of moderately curved root canals using the XP single file and the TS file system were equally effective. XP and TS maintained the original anatomy of the root canals and showed a similar percentage of untreated canal walls, centered ability, and minimal apical transportation.

Efectividad bactericida del diamino fluoruro de plata a diferente concentración sobre estreptococos cariogénicos en muestras de saliva y dentina de escolares: un estudio in vitro / Bactericidal effectveness of silver diamine fluoride in different concentrations on cariogenic Streptococcus in salivary and dentinal samples of schoolchildren: an in vitro study

La OMS y la FDI han publicado que entre el 60 y 90% de los escolares padecen caries. En nuestro país, el Sistema de Vigilancia Epidemiológica de Patologías Orales (SIVEPAB) 2012, reporta un 85% de caries a nivel nacional en población pediátrica. Los agentes anticariogénicos como el diamino y el fluoruro de plata son un tratamiento alentador, este agente puede actuar como bactericida o bacteriostático en función de su concentración y su capacidad para inhibir el crecimiento de estreptococos del grupo viridans, y por ende, de la caries. Problema: ¿Cuál es la efectividad bactericida del diamino fluoruro de plata (Saforide®) a diferente concentración sobre la microbiota cariogénica de escolares? Objetivo: Determinar la eficacia bactericida del diamino fluoruro de plata (DFP) a diferentes concentraciones en el crecimiento bacteriano de Streptococcus mitis, S. mutans y S. salivarius en muestras de saliva y dentina en escolares. Material y métodos: Se llevó a cabo un estudio experimental con una variable independiente, el efecto bactericida del diamino fluoruro de plata y se tomó el halo de inhibición como la dependiente. Se utilizaron medidas descriptivas como prueba de comparación y análisis de varianza usando post-hoc Tukey≠ con una confianza del 95%, y análisis de datos exploratorios. Resultados: Se analizaron 100 muestras, de las cuales 48.3% correspondió a S. mutans, 41.4% a S. salivarius y 10.3% a S. mitis, se obtuvo una mayor zona de inhibición para las tres bacterias al 38% mostrando una diferencia estadísticamente significativa 12% (p < 0.05). También se observó un efecto bacteriostático al 12%, no así para el 38%, donde se encontró un efecto bactericida Conclusión: Nuestros resultados sugieren que al 38% de la concentración hay un claro efecto bactericida en el grupo de estreptococos viridans y el 12% no se recomienda para la detención de caries debido al efecto bacteriostático (AU)

WHO and FDI have ruled that 60-90% of schoolchildren are affected by caries. In our country, the System of Epidemiological Surveillance of Oral Pathologies (SIVEPAB) (SIVEPAB) 2012. Report a rate of 85% of caries nationally in pediatric population. Anticariogenic diamino agents such as silver fluoride are an encouraging decrease in treatment for these high rates of tooth decay in our country, this agent can act as bactericidal or bacteriostatic based on their concentration and their ability to inhibit endogenous metalloproteinase (MMP-2, 8, 9). Problem: What will be the bactericidal effectiveness of silver diamine fluoride different concentration on cariogenic Streptococci saliva samples taken from school and dentin? Objective: Determine the bactericidal effectiveness Silver diamine fluoride (SDF) to different concentration on bacterial growth of Streptococcus mitis, S. mutans, and S. salivarius in saliva samples and dentin in school. Material and methods: An experimental study was conducted as an independent variable the bactericidal effect of silver diamine fluoride was taken as dependent inhibition halo. Descriptive measures were used as a comparison test and analysis of variance using Post-hoc Tukey with 95% confidence, and exploratory data analysis. Results: One hundred samples, of which 48.3% corresponded to S. mutans, 41.4% to S. salivarius and 10.3% to S. mitis, were analyzed, we obtained a larger zone of inhibition for all three organisms at 38% showing a statistically significant difference from 12% (p < 0.05). It was also observed that the 12% sample bacteriostatic effect, not to the concentration of 38% was found a bactericidal effect. Conclusion: Our results suggest that 38% concentration has a bactericidal effect on Streptococcus viridans group and 12% showed not recommended for the arrest or detention of dentine caries bacteriostatic effect (AU)

Association of excessive GWG with adiposity indicators and metabolic diseases of their offspring: systematic review.

INTRODUCTION: It has been reported that excessive gestational weight gain (GWG) during pregnancy is associated with an increase in adiposity indicators and metabolic disorders of the offspring. OBJECTIVE: The objective of this review, using the Institute of Medicine (IOM) criteria, was to analyze the association of excessive GWG in prospective studies with the adiposity indicators and metabolic diseases of the offspring, and the association of excessive GWG with adiposity indicators and metabolic disease of the ≥ 15 years offspring. METHODS: An electronic search was conducted in the MEDLINE/PubMed, EMBASE, and CINAHL databases of prospective cohort studies published from January 2004 to September 2014. Selection was restricted to prospective cohort studies where the definition of GWG was used according to the IOM-recommendations; and prospective cohort studies including offspring ≥ 15 years, independent of using the definition for excessive GWG. RESULTS: Nine prospective cohort studies meet the inclusion criteria. Five studies used the IOM-recommendations for assessing GWG, and six studies assessed adiposity or metabolic indicators of their offspring at ≥ 15 years. In seven of the nine studies, excessive GWG was associated with adiposity and metabolic diseases. Due to the limitations found, the evidence of the association was shown to be low. CONCLUSIONS: The results of this review showed, that independently of the criteria used to diagnose excessive GWG, all the included studies, consistently showed an association of excessive GWG with adiposity indicators or other components of metabolic disease early in life, during adolescence or adulthood. However, due to the limitations of the studies the strength of the evidence was low. Better designed studies are warranted to confirm a stronger evidence.

Introducción Se ha reportado que el aumento excesivo de la ganancia de peso gestacional (GPG) durante el embarazo está asociada a un aumento en los indicadores de adiposidad y trastornos metabólicos de su descendencia. Objetivo El objetivo fue analizar la asociación del aumento excesivo de GPG en estudios prospectivos, utilizando los criterios del Instituto de medicina (IOM), con indicadores de adiposidad y enfermedades metabólicas de los descendientes y estudiar la asociación del aumento excesivo de GPG en estudios prospectivos con indicadores de adiposidad y enfermedad metabólica de los descendientes ≥ 15 años. Métodos Se realizó una búsqueda electrónica en las bases de datos MEDLINE/PubMed EMBASE y CINAHL, de estudios prospectivos de cohorte publicados de enero de 2004 a septiembre de 2014. La selección de artículos fue restringida a estudios en los que la definición de GPG siguiera las recomendaciones del IOM; y estudios prospectivos de cohorte incluyendo los descendientes ≥ a 15 años de edad, con diferentes definiciones de GPG, independiente de la definición utilizada. Resultados Nueve estudios prospectivos cumplieron los criterios de inclusión. Cinco estudios utilizaron las recomendaciones del IOM para la evaluación de GPG, y seis estudios evaluaron indicadores de adiposidad o enfermedades metabólicas en los descendientes ≥ 15 años. En siete de los nueve estudios, se observó que a mayor GPG de la madre, de cualquier categoría de peso pre gestacional, mayor adiposidad y prevalencia de otros componentes del síndrome metabólico. Debido a las limitaciones explicadas en el estudio la evidencia de la asociación es baja. Conclusiones Los resultados de esta revisión muestran que independientemente de los criterios utilizados para diagnosticar el aumento de la GPG, todos los estudios muestran consistentemente una asociación entre la GPG y los indicadores de adiposidad u otros componentes del síndrome metabólico en la niñez, durante la adolescencia o la edad adulta. Sin embargo, debido a las limitaciones de los estudios, la fuerza de la evidencia es baja. Son necesarios estudios mejor diseñados para confirmar esta asociación con una mayor fuerza de la evidencia.

A dehydrin-dehydrin interaction: the case of SK3 from Opuntia streptacantha.

Dehydrins belongs to a large group of highly hydrophilic proteins known as Late Embryogenesis Abundant (LEA) proteins. It is well known that dehydrins are intrinsically disordered plant proteins that accumulate during the late stages of embryogenesis and in response to abiotic stresses; however, the molecular mechanisms by which their functions are carried out are still unclear. We have previously reported that transgenic Arabidopsis plants overexpressing an Opuntia streptacantha SK3 dehydrin (OpsDHN1) show enhanced tolerance to freezing stress. Herein, we show using a split-ubiquitin yeast two-hybrid system that OpsDHN1 dimerizes. We found that the deletion of regions containing K-segments and the histidine-rich region in the OpsDHN1 protein affects dimer formation. Not surprisingly, in silico protein sequence analysis suggests that OpsDHN1 is an intrinsically disordered protein, an observation that was confirmed by circular dichroism and gel filtration of the recombinantly expressed protein. The addition of zinc triggered the association of recombinantly expressed OpsDHN1 protein, likely through its histidine-rich motif. These data brings new insights about the molecular mechanism of the OpsDHN1 SK3-dehydrin.
