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.

Steering the Microbiota-Gut-Brain Axis by Antibiotics to Model Neuro-Immune-Endocrine Disorders.

Background: Over the last century, animal models have been employed to study the gut-brain axis and its relationship with physiological processes, including those necessary for survival, such as food intake and thermoregulation; those involved in diseases, ranging from inflammation to obesity; and those concerning the development of neurodegenerative diseases and neuropsychiatric disorders, such as Alzheimer's disease and autism spectrum disorder, respectively.

Summary: The gut microbiota has been recognized in the last decade as an essential functional component of this axis. Many reports demonstrate that the gut microbiota influences the development of a vast array of physiological processes.

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.

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.

Real-life cost-effectiveness of benralizumab in patients with severe asthma.

Background: Availability of clinically effective and cost-effective treatments for severe asthma would be beneficial to patients and national healthcare systems. The aim of this study was to evaluate clinical outcomes and healthcare expenditure after incorporating benralizumab into the standard treatment of refractory eosinophilic asthma.

Methods: This was a cross-sectional multicentre study of consecutive patients with refractory eosinophilic asthma who received treatment with benralizumab during at least 12 months.

Sensory and memory processing in old female and male Wistar rat brain, and its relationship with the cortical and hippocampal redox state.

The brain is one of the most sensitive organs damaged during aging due to its susceptibility to the aging-related oxidative stress. Hence, in this study, the sensory nerve pathway integrity and the memory were evaluated and related to the redox state, the antioxidant enzymes function, and the protein oxidative damage in the brain cortex (Cx) and the hippocampus (Hc) of young (4-month-old) and old (24-month-old) male and female Wistar rats. Evoked potentials (EP) were performed for the auditory, visual, and somatosensory pathways.

Real-life experience with benralizumab during 6 months.

Background: Benralizumab is a monoclonal antibody that binds to the human interleukin-5 (IL-5) receptor (IL-5R), thereby preventing IL-5 from binding to its receptor and inhibiting differentiation and maturation of eosinophils in the bone marrow. Because of its recent marketing approval, sufficient real-life evidence is lacking to confirm the efficacy and safety data from clinical trials. The purpose of this study was to evaluate the efficacy and safety of benralizumab for the treatment of severe refractory eosinophilic asthma in a real-world cohort of patients.

5,10-Dihydrobenzo[ a]indolo[2,3- c]carbazoles as Novel OLED Emitters.

The excited-state dynamics of four 5,10-dihydrobenzo[ a]indolo[2,3- c]carbazoles in solution and in films were studied with stationary and time-resolved spectroscopies. The solvent dependency of the photophysics reveals no appreciable dipole moment in the ground state. In the excited state, electron-withdrawing substituents contribute to an outspoken charge-transfer character.

Postnatal overnutrition alters the orexigenic effects of melanin-concentrating hormone (MCH) and reduces MCHR1 hypothalamic expression on spontaneous feeding and fasting.

One of the approaches to induce obesity in rodents consists in reducing litter size to 3 pups during the lactation period. Animals submitted to this manipulation are heavier, hyperphagic and develop several metabolic diseases for the rest of their lives. In the present study, under the premise that melanin-concentrating hormone (MCH), an orexigenic peptide synthesized by neurons of the lateral hypothalamus, is involved in food intake regulation, we aimed to measure the hypothalamic expression of its receptor, MCHR1, in adult early overfed obese animals and normoweight controls at both ad libitum and food deprived conditions.

Organization and structure of mixed Langmuir films composed of polydiacetylene and hemicyanine.

Mixed Langmuir monolayers of 10,12-Pentacosadiynoic acid (DA) monomer and an amphiphilic Hemicyanine dye derivative have been formed at the air/water interface. Two derivatives of docosylpyridinium have been used, with either one included in the monolayer in 1:1molar ratio. The DA monomers within the mixed monolayers have been polymerized in situ at the air/water interface.

Octadecyl-viologen Photooxidation in Surface Films: Macroscopic Contraction of Langmuir Monolayer by UV Irradiation.

The effects of UV radiation on a viologen derivative, octadecylviologen (OV), in Langmuir monolayers at the air-aqueous solution interface and in Langmuir-Blodgett (LB) films have been investigated. Langmuir monolayers suffer a sharp contraction after UV irradiation, clearly visible by the drop in surface pressure or the loss of surface area observed in the surface pressure-area isotherms. The UV-vis reflection measurements reveal a deep change in the OV monolayer caused by a photochemical reaction, which suggests the pyridones formation as photoreaction products.

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.

2-Arachidonoylglycerol into the lateral hypothalamus improves reduced sleep in adult rats subjected to maternal separation.

We have previously reported that maternal separation (MS) for 3 h daily during the first two postnatal weeks increases wakefulness, whereas it reduces sleep in rats. Oleamide, an agonist of the cannabinoid receptor type 1, increases sleep in MS rats to such a level that we cannot differentiate their sleep patterns from those of their non-MS (NMS) siblings. However, 2-arachidonoylglycerol (2-AG), an endocannabinoid, infused into the lateral hypothalamus of NMS rats at the beginning of the dark phase of the cycle increases rapid eye movement sleep and the expression of c-Fos on the rapid eye movement sleep promoting melanin-concentrating hormone neurons.

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.

Inhibition of diacylglycerol lipase (DAGL) in the lateral hypothalamus of rats prevents the increase in REMS and food ingestion induced by PAR1 stimulation.

Stimulation of the protease-activated receptor 1 (PAR1) in vitro, was shown to induce synaptic retrograde signaling through the endocannabinoid 2-arachidonoylglycerol (2-AG) synthesis and activation of the cannabinoid receptor type 1 (CB1R). The activation of PAR1 by the agonist S1820 in the lateral hypothalamus (LH) increases rapid eye movement sleep (REMS) and food intake in rats, and both effects are prevented by the CB1R inverse agonist AM251. In the present study, we implanted rats with electrodes and with cannulae aimed bilaterally to the LH.

UV-Vis reflection spectroscopy under variable angle incidence at the air-liquid interface.

The UV-Vis reflection spectroscopy (UV-Vis-RS) in situ at the air-liquid interface provides information about tilt and aggregation of chromophores in Langmuir monolayers. This information is particularly important given in most cases the chromophore is located at the polar region of the Langmuir monolayer. This region of the Langmuir monolayers has been hardly accessible by other experimental techniques.

2-AG into the lateral hypothalamus increases REM sleep and cFos expression in melanin concentrating hormone neurons in rats.

Orexins/hypocretins (OX) and melanin-concentrating hormone (MCH) neurons located in the lateral hypothalamus seem to modulate different stages of the sleep-wake cycle. OX are necessary for wakefulness and MCH appears to regulate rapid eye movement sleep (REMS). Likewise, endocannabinoids, the endogenous ligands for cannabinoid receptors 1 and 2 (CB1R, CB2R), also modulate REMS in rats.

Structural diversity from the transannular cyclizations of natural germacrone and epoxy derivatives: a theoretical-experimental study.

Treatment of germacrone (1) with different electrophiles, and of its epoxy derivatives germacrone-4,5-epoxide (2), germacrone-1,10-epoxide (3) and isogermacrone-4,5-epoxide (4) with Brönsted/Lewis acids and Ti(III), gives rise to a great structural diversity. Thus, by using a maximum of two steps, the production of more than 40 compounds corresponding to 14 skeletons is described. Computational calculations rationalizing the structural divergence produced are also described.
