Effectiveness of Treatment Approaches in COVID-19 Pneumonia: A Comparative Evaluation between a Specialized Center and Conventional Hospitals.

BACKGROUND: The early stages of the COVID-19 pandemic overwhelmed general hospitals in Spain. In response, a dedicated hospital for COVID-19 care, the Hospital de Emergencias Enfermera Isabel Zendal (HEEIZ), was established. This study aimed to compare clinical outcomes of COVID-19 patients treated at the specialized HEEIZ with those at conventional general hospitals (CGHs) in Madrid, Spain. METHODS: The study was a prospective, observational cohort study including COVID-19 patients admitted to the HEEIZ and 14 CGHs (December 2020 to August 2021). Patients were assigned based on hospital preference. Clinical data were collected and analyzed using multivariate regression to assess primary and secondary outcomes, including hospital mortality, need of invasive mechanical ventilation (IMV), and pharmacological treatments. RESULTS: The HEEIZ cohort (n = 2997) was younger and had lower Charlson comorbidity scores than the CGH cohort (n = 1526). Adjusted HEEIZ hospital mortality was not significantly higher compared with CGHs (OR: 1.274; 95% CI: 0.781-2.079; p = 0.332). CONCLUSIONS: During the study period, patients admitted to the HEEIZ showed no significant differences in clinical outcomes, compared with patients admitted at CGHs. These results might support the use of specialized centers in managing pandemic surges, allowing CGHs to handle other needs.

Xenoestrogen concentration in women with endometriosis or leiomyomas: A case-control study.

BACKGROUND: Xenoestrogens are synthetic or naturally occurring chemicals capable of altering the endocrine system of humans and animals owing to their molecular similarity to endogenous hormones. There is limited data regarding their effects on women´s health. Chronic exposure to xenoestrogens can promote the development of estrogen-related diseases. OBJECTIVES: To examine xenoestrogen concentration (TEXB-α) differences between women with leiomyomas or endometriosis and control women, and to study the relationship between the clinical and sociodemographic characteristics of these patients and their xenoestrogen levels. METHODS: Prospective case-control study. We selected 221 women who underwent surgery at Quironsalud Madrid University Hospital between 2017 and 2021. The cases included 117 patients: 74 women who underwent surgery for uterine leiomyomas, 21 with endometriosis, and 22 with both pathologies. The control group comprised 104 healthy women who underwent surgical procedures for other reasons. TEXB-α was determined in the omental fat of all patients. Using a questionnaire and reviewing the patients' medical records, we collected sociodemographic data and other relevant variables. RESULTS: A significant majority of study participants (68.8%) had detectable levels of xenoestrogens. We found no association between TEXB-α levels in omental fat and the presence of myomas or endometriosis. In the case group, women living or working in Madrid Community exhibited, on average, 3.12 Eeq pM/g higher levels of TEXB-α compared to those working in other areas (p = 0.030). Women who referred to the use of estrogen-containing hormonal contraceptives had, on average, 3.02 Eeq pM/g higher levels of TEXB-α than those who had never used them (p = 0.022). CONCLUSIONS: This study found no association between omental xenoestrogen levels and leiomyomas or endometriosis. However, their presence in most participants and their association with highly polluted areas emphasizes the importance of limiting environmental exposure to these substances. We also identified an association between hormonal contraceptive use and xenoestrogen concentration.

Novel portable hypothermic machine perfusion preservation device enhances cardiac viability of donated human hearts.

Introduction: Heart transplant remains the gold standard treatment for patients with advanced heart failure. However, the list of patients waiting for a heart transplant continues to increase. We have developed a portable hypothermic oxygenated machine perfusion device, the VP.S ENCORE®, to extend the allowable preservation time. The purpose of this study was to test the efficacy of the VP.S. ENCORE® using deceased donors derived hearts. Methods: Hearts from brain-dead donors not utilized for transplant (n = 11) were offered for research from the Texas Organ Sharing Alliance (TOSA), South and Central Texas' Organ Procurement Organization (OPO) and were preserved in the VP.S ENCORE® for 4 (n = 2), 6 (n = 3), and 8 (n = 3) hours or were kept in static cold storage (SCS) (n = 3). After preservation, the hearts were placed in an isolated heart Langendorff model for reperfusion and evaluated for cardiac function. Results: The mean donor age was 37.82 ± 12.67 with the youngest donor being 19 and the oldest donor being 58 years old. SCS hearts mean weight gain (%) was -1.4 ± 2.77, while perfused at 4 h was 5.6 ± 6.04, perfused at 6 h 2.1 ± 6.04, and 8 h was 7.2 ± 10.76. Venous and arterial lactate concentrations were less than 2.0 mmol/L across all perfused hearts. Left ventricular contractility (+dPdT, mmHg/s) for 4 h (1,214 ± 1,064), 6 (1,565 ± 141.3), and 8 h (1,331 ± 403.6) were within the range of healthy human heart function. Thus, not significant as compared to the SCS group (1,597 ± 342.2). However, the left ventricular relaxation (mmHg/s) was significant in 6-hour perfused heart (p < 0.05) as compared to SCS. Gene expression analysis of inflammation markers (IL-6, IL-1ß) showed no significant differences between SCS and perfused hearts, but a 6-hour perfusion led to a downregulated expression of these markers. Discussion: The results demonstrate that the VP.S ENCORE® device enhances cardiac viability and exhibits comparable cardiac function to a healthy heart. The implications of these findings suggest that the VP.S ENCORE® could introduce a new paradigm in the field of organ preservation, especially for marginal hearts.

Cyclosporine A in hospitalized COVID-19 pneumonia patients to prevent the development of interstitial lung disease: a pilot randomized clinical trial.

Post-COVID-19 interstitial lung disease (ILD) is a new entity that frequently causes pulmonary fibrosis and can become chronic. We performed a single-center parallel-group open-label pilot randomized clinical trial to investigate the efficacy and safety of cyclosporine A (CsA) in the development of ILD in the medium term among patients hospitalized with COVID-19 pneumonia. Patients were randomized 1:1 to receive CsA plus standard of care or standard of care alone. The primary composite outcome was the percentage of patients without ILD 3 months after diagnosis of pneumonia and not requiring invasive mechanical ventilation (IMV) (response without requiring IMV). The key secondary composite outcomes were the percentage of patients who achieve a response requiring IMV or irrespective of the need for IMV, and adverse events. A total of 33 patients received at least one dose of CsA plus standard of care (n = 17) or standard of care alone (n = 16). No differences were found between the groups in the percentage of patients who achieved a response without requiring IMV or a response requiring IMV. A higher percentage of patients achieved a response irrespective of the need for IMV in the CsA plus standard of care group although the RR was almost significant 2.833 (95% CI, 0.908-8.840; p = 0.057). No differences were found between the groups for adverse events. In hospitalized patients with COVID-19 pneumonia, we were unable to demonstrate that CsA achieved a significant effect in preventing the development of ILD.

Jorge clinical study: 10-year outcomes of risk-adapted radiotherapy defined by multiparametric MRI for prostate cancer.

PURPOSE: To analyze the 10-year biochemical relapse-free survival (BRFS), locoregional relapse-free survival (LRFS), metastasis-free survival (MFS), and overall survival (OS) in patients diagnosed with localized prostate adenocarcinoma treated with radiotherapy (RT) ± androgen deprivation therapy (ADT), according to the risk groups based on multiparametric magnetic resonance imaging (mpMRI) instead of digital rectal exam (DRE). METHODS: We retrospectively evaluated 140 consecutive patients diagnosed with localized prostate adenocarcinoma, stratified into different risk groups-low (LR), intermediate (IR), and high (HR) by mpMRI results. RESULTS: After a median follow-up of 104 months, in LR group (n = 15), 10-year BRFS was 86.7%, 10-year LRFS was 86.7%, 10-year MFS was 93.3%, and 10-year OS was 100%. In IR group (n = 80), 10-year BRFS was 80.5%, 10-year LRFS was 86.1%, 10-year MFS was 92.6%, and 10-year OS was 76%. In HR group (n = 45), 10-year BRFS was 72.8%, 10-year LRFS was 78.7%, 10-year MFS was 82.1%, and 10-year OS was 77% (2 deaths from prostate cancer). According to mpMRI results, 36 (25.7%) patients change the risk group and 125 (89.28%) patients change the TNM stage. There was a trend for higher metastatic relapse in patients who switched from IR to HR (due to mpMRI) versus the patients who remained in the IR (20%, vs. 1.81% p = 0.059). Multivariate analysis showed that locoregional relapse was strongly associated with distant relapse (OR = 9.28; 95%CI: 2.60-33.31). There were no cases of acute grade 3 toxicity. Late grade 3 genitourinary, gastrointestinal, and sexual toxicity were 2.8%, 0.7%, and 1.2%, respectively. CONCLUSION: This is the first study with a 10-year median follow-up of patients diagnosed with localized prostate cancer treated with radiotherapy according to the risk groups established by mpMRI. Our findings show that mpMRI is a key tool to diagnose and establish risk groups in these patients, to optimize their treatment.

Consequences of Purtscher-Like Retinopathy in a Patient With Systemic Lupus Erythematosus: A Case Report.

We report on a case of Purtscher-like retinopathy (PLR) secondary to systemic lupus erythematosus, which caused retinal ischemia, retinal neovascularization, vitreous hemorrhage, and, ultimately, a combined tractional and rhegmatogenous retinal detachment. A 23-year-old male presented with decreased visual acuity in the left eye (OS). He had a recent history of systemic lupus erythematosus and was being treated with systemic corticosteroids. At presentation, his visual acuity was counting fingers in the OS; a fundus examination of the OS revealed the presence of macular edema associated with flame hemorrhages, diffuse cotton-wool spots surrounding the macula, and vascular sheathing with the retina attached, all of which were consistent with PLR. Five months later, his fundus examination (OS) showed severe retinal ischemia and active neovascularization. The patient was scheduled for pan-retinal photocoagulation (PRP) laser therapy, but he was lost to follow-up. Subsequently, he returned two months later with progressive damage and was treated with PRP in the OS. An additional two months after PRP treatment, an examination revealed combined tractional and rhegmatogenous retinal detachment. Ultimately, the patient required a pars plana vitrectomy.

Bilateral Acute Iris Transillumination Syndrome Following Oral Moxifloxacin Overdose.

We report a case of bilateral acute iris transillumination (BAIT) syndrome caused by an overdose of oral moxifloxacin in a Hispanic female patient with no previous respiratory viral infection. A 56-year-old Hispanic female with no history of ocular illness was referred to our glaucoma service to manage her microcystic edema, swelling, and refractory ocular hypertension. Her ocular and systemic symptoms, including progressively worsening bilateral ocular pain, severe photophobia, blurred vision, nausea, and vomiting, started 14 days after an accidental overdose of oral moxifloxacin. Moxifloxacin had been prescribed to treat a complicated urinary tract infection. A slit-lamp examination revealed bilateral microcystic corneal edema and transillumination in the right temporal iris, both consistent with a diagnosis of BAIT syndrome. The existing literature on BAIT syndrome is scarce, and its etiology remains unclear. This case provides clinical evidence supporting moxifloxacin toxicity as a possible cause of BAIT syndrome. We emphasize the importance of conducting extensive research to define the mechanisms involved in moxifloxacin-induced BAIT syndrome and to search for other potential etiologies of this condition.

The Real-World Study of Immunogenicity and Safety of the Adjuvant Recombinant Vaccine against Varicella Zoster Virus in Patients with Immune-Mediated Inflammatory Diseases Treated with Janus Kinase Inhibitors.

Background. The risk of herpes zoster reactivation is increased in immunocompromised patients, especially in those with immune-mediated inflammatory diseases (IMIDs) on Janus kinase inhibitor (JAKi) treatment. The recombinant subunit herpes zoster vaccine (RZV) is a non-live vaccine, recently approved for this subgroup of patients, which shows high rates of vaccine effectiveness, with few adverse effects reported in clinical trials. Purpose. The aim of this real-world study was to determine the immunogenicity and safety of RZV in IMID patients on JAKi treatment. Methods. The increase in the concentration of anti-gE antibody for varicella zoster virus post-vaccination, compared to the pre-vaccination concentration, was analyzed to test the humoral immune response. Adverse effects after the first and second vaccine doses were registered. Results. In total, 49 patients were analyzed, and a fourfold increase in antibody concentration was achieved in almost 40% of subjects, with only one serious local adverse effect. Discussion. The resulting immunogenicity was lower than that observed in clinical trials, probably due to the presence of immune disease and immunosuppressive treatment, and to the fact that this was a real-world study. No differences in response according to age, previous virus zoster reactivation, or concomitant treatments were found. Conclusions. RZV was well tolerated and reached the immune response objective in 40% of patients. These results reinforce the importance of including RZV vaccination for immunosuppressed patients. Real-world studies regarding vaccine effectiveness are still needed in order to gain a full understanding of the response to RZV in this group of patients.

Single Systemic Administration of a Gene Therapy Leading to Disease Treatment in Metachromatic Leukodystrophy Arsa Knock-Out Mice.

Metachromatic leukodystrophy (MLD) is a rare, inherited, demyelinating lysosomal storage disorder caused by mutations in the arylsulfatase-A gene (ARSA). In patients, levels of functional ARSA enzyme are diminished and lead to deleterious accumulation of sulfatides. Herein, we demonstrate that intravenous administration of HSC15/ARSA restored the endogenous murine biodistribution of the corresponding enzyme, and overexpression of ARSA corrected disease biomarkers and ameliorated motor deficits in Arsa KO mice of either sex. In treated Arsa KO mice, when compared with intravenously administered AAV9/ARSA, significant increases in brain ARSA activity, transcript levels, and vector genomes were observed with HSC15/ARSA Durability of transgene expression was established in neonate and adult mice out to 12 and 52 weeks, respectively. Levels and correlation between changes in biomarkers and ARSA activity required to achieve functional motor benefit was also defined. Finally, we demonstrated blood-nerve, blood-spinal and blood-brain barrier crossing as well as the presence of circulating ARSA enzyme activity in the serum of healthy nonhuman primates of either sex. Together, these findings support the use of intravenous delivery of HSC15/ARSA-mediated gene therapy for the treatment of MLD.SIGNIFICANCE STATEMENT Herein, we describe the method of gene therapy adeno-associated virus (AAV) capsid and route of administration selection leading to an efficacious gene therapy in a mouse model of metachromatic leukodystrophy. We demonstrate the therapeutic outcome of a new naturally derived clade F AAV capsid (AAVHSC15) in a disease model and the importance of triangulating multiple end points to increase the translation into higher species via ARSA enzyme activity and biodistribution profile (with a focus on the CNS) with that of a key clinically relevant biomarker.

Características de los pacientes con neoplasias hematológicas y con tumores sólidos atendidos por un equipo de soporte paliativo hospitalario / Characteristics of patients with hematological and solid tumors malignancies attended by a hospital palliative care service

Antecedentes y objetivo: El interés por la atención paliativa en pacientes con neoplasias hematológicas está aumentando. Nuestro objetivo es describir las características de pacientes oncológicos valorados por un equipo de soporte paliativo en un hospital terciario y analizar las diferencias entre pacientes hematológicos y con tumores sólidos. Método: Estudio observacional descriptivo longitudinal retrospectivo con una cohorte de pacientes hospitalizados con enfermedad oncológica (hematológica o tumor sólido) valorados por equipo de soporte paliativo hospitalario. Comparamos variables clínicas, asistenciales y de supervivencia. El análisis de datos se realizó con la versión 15 del programa SPSS. Resultados: De enero de 2015 a diciembre de 2018 se valoraron 1025 pacientes oncológicos (10,8 % hematológicos, 89,2 % sólidos). No se encontraron diferencias en situación funcional medida por la Palliative Performance Scale, presentación de síntoma principal, porcentaje de pacientes con dolor, tiempo de seguimiento ni en porcentaje de fallecidos en el ingreso en que fueron valorados. El paciente hematológico, comparado con el oncológico, tiene menos tratamiento opioide pautado (43 vs. 53 %; p = 0,035), es seguido con más frecuencia por recurso paliativo hospitalario que domiciliario (46,55 vs. 29,44 % el primero; 15,5 vs. 33,06 % el segundo; p = 0,001 en distribución) y fallece más en hospital (82,9 vs. 65,5 %; p = 0,024). Conclusiones: Los pacientes con neoplasia hematológica presentan una carga sintomática similar a los pacientes con tumor sólido. Es importante identificar mejor sus necesidades para que puedan beneficiarse, como se ha demostrado con los pacientes oncológicos, de la atención integrada junto a los servicios de hematología con modelos de intervención acordes a sus necesidades y las trayectorias específicas de las enfermedades hematológicas.

Background and objective: Interest in palliative care for patients with hematologic malignancies is increasing. Our goal is to describe the features of cancer patients evaluated by a supportive and palliative care service in a tertiary referral hospital, and to analyze the differences between patients with hematological malignancies and solid tumors. Method: A retrospective longitudinal descriptive observational study was carried out in a cohort of hospitalized patients with oncological diseases (hematological or solid tumor) evaluated by a palliative care service. We compared clinical, healthcare and survival variables between both groups. The analysis was performed using the SPSS v.15 package. Results: From January 2015 to December 2018, 1025 cancer patients were evaluated (10.8 % hematological tumor, 89.2 % solid tumors). No differences were found in functional status as measured by the Palliative Performance Scale, presentation of main symptom, percentage of patients with pain, time of follow-up, or percentage of deaths on admission to the evaluation. The hematological patient, compared to the oncological one, has less prescribed opioid treatment (43 % vs 53 %, p = 0.035), received greater hospital palliative care rather than home-based care (46.55 % vs 29.44 % the former and 15.5 % vs 33.06 % the latter, p = 0.001), and dies more frequently in a hospital (82.9 % vs. 65.5 %, p = 0.024). Conclusions: Patients with hematological malignancies present a symptomatic burden similar to that of those with solid tumors. It is important to better identify their needs so that they can benefit, as has been demonstrated with cancer patients, from integrated care together with hematology services using intervention models according to their needs and specific disease trajectories.

Chemical characterization and anaerobic treatment of bitumen fume condensate using a membrane bioreactor.

Bitumen fume condensate (BFC) is a hazardous wastewater generated at asphalt reclamation and production sites. BFC contains a wide variety of potentially toxic organic pollutants that negatively affect anaerobic processes. In this study, we chemically characterized BFC produced at an industrial site and evaluated its degradation under anaerobic conditions. Analyses identified about 900 compounds including acetate, polycyclic aromatic hydrocarbons, phenolic compounds, and metal ions. We estimated the half maximal inhibitory concentrations (IC50) of methanogenesis of 120, 224, and 990 mgCOD·L-1 for three types of anaerobic biomass, which indicated the enrichment and adaptation potentials of methanogenic biomass to the wastewater constituents. We operated an AnMBR (7.0 L, 35 °C) for 188 days with a mixture of BFC, phenol, acetate, and nutrients. The reactor showed a maximum average COD removal efficiency of 87.7 ± 7.0 %, that corresponded to an organic conversion rate of 286 ± 71 mgCOD-1·L-1d-1. The microbial characterization of the reactor's biomass showed the acetoclastic methanogen Methanosaeta as the most abundant microorganism (43 %), whereas the aromatic and phenol degrader Syntrophorhabdus was continuously present with abundances up to 11.5 %. The obtained results offer the possibility for the application of AnMBRs for the treatment of BFC or other petrochemical wastewater.

The effect of age on clinical outcomes in critically ill brain-injured patients.

PURPOSE: We studied the impact of age on survival and functional recovery in brain-injured patients. METHODS: We performed an observational cohort study of all consecutive adult patients with brain injury admitted to ICU in 8 years. To estimate the optimal cut-off point of the age associated with unfavorable outcomes (mRS 3-6), receiver operating characteristic (ROC) curve analyses were used. Multivariate logistic regression analyses were performed to identify prognostic factors for unfavorable outcomes. RESULTS: We included 619 brain-injured patients. We identified 60 years as the cut-off point at which the probability of unfavorable outcomes increases. Patients ≥ 60 years had higher severity scores at ICU admission, longer duration of mechanical ventilation, longer ICU and hospital stays, and higher mortality. Factors identified as associated with unfavorable outcomes (mRS 3-6) were an advanced age (≥ 60 years) [Odds ratio (OR) 4.59, 95% confidence interval (CI) 2.73-7.74, p < 0.001], a low GCS score (≤ 8 points) [OR 3.72, 95% CI 1.95-7.08, p < 0.001], the development of intracranial hypertension [OR 5.52, 95% CI 2.70-11.28, p < 0.001], and intracerebral hemorrhage as the cause of neurologic disease [OR 3.87, 95% CI 2.34-6.42, p < 0.001]. CONCLUSION: Mortality and unfavorable functional outcomes in critically ill brain-injured patients were associated with older age (≥ 60 years), higher clinical severity (determined by a lower GCS score at admission and the development of intracranial hypertension), and an intracerebral hemorrhage as the cause of neurologic disease.

Stress, subjective wellbeing and self-knowledge in higher education teachers: A pilot study through bodyfulness approaches.

Work-related stress is a major cause of health problems worldwide. Faculty in educational institutions, including universities, also face high levels of stress, which undoubtedly affects their performance, level of personal satisfaction and wellbeing, and the relationship with students. Training interventions based on embodied learning can promote self-knowledge, emotional regulation and stress reduction, thereby increasing levels of psychological well-being. The present pilot study analyzed the impact of body awareness training in 31 university teachers using a controlled, randomized pre-post experimental design, with two experimental groups and a control group (n = 10). The two interventions were: Hatha Yoga (n = 11) and Dance Movement Therapy/Body Mind Centering (n = 10), which we have termed Body Movement Awareness. Variables related to body awareness, mindfulness, wellbeing, life satisfaction and stress were measured using self-perception tests. Cortisol levels, heart rate variability and sleep quality were also analyzed. Finally, participants' reflections were analyzed according to a qualitative approach. The results showed significant differences between the control group and the Hatha Yoga group in terms of stress reduction and wellbeing. The Body Movement Awareness group exhibited evidence of contributions on self-knowledge, communication and kinesthetic empathy, key elements in the educational field. Despite the inherent limitations of the study, the conclusions are encouraging and open new lines of research from embodied approaches that introduce creative movement and group experience as part of the process of emotional regulation and self-knowledge.

Effectiveness of Physical Exercise Interventions on Pulmonary Function and Physical Fitness in Children and Adults with Cystic Fibrosis: A Systematic Review with Meta-Analysis.

Objective: Physical exercise is associated with several benefits in the treatment of cystic fibrosis (CF), associated with a reduction in patient mortality. The aim of this systematic review was to determine the effectiveness of exercise interventions on physical condition and lung function in children and adults with CF to establish the most appropriate type and dose of physical exercise used so far. Methods: The studies included were randomized controlled trials with physical exercise interventions performed with children or adults with CF, analyzing the effects on pulmonary function, cardiorespiratory capacity, and muscle strength. The variables analyzed in at least four studies in the same population (children or adults) with the same measuring test were included in the meta-analysis. Results:Pulmonary function: There were no changes in the forced expiratory volume 1 s, but mouth expiratory/inspiratory pressures were improved in some studies. Physical fitness: In children, the interventions did not manage to improve the VO2peak (SMD = 0.22; 95%CI: -0.25 to 0.68; p = 0.73) but improved muscle strength. In adults, physical exercise interventions based on high-intensity aerobic training showed positive results in the VO2peak, and in some muscle strength outcomes. Conclusions: Exercise interventions in children and adults with CF are effective in improving muscle strength, cardiovascular capacity, and respiratory muscle function. However, they do not achieve improvements in lung function. The most effective programs are those using strength training or cardiovascular high-intensity interval training, although to date there have been few such interventions.

Laparoscopic Single-Port versus Mini-Laparoscopic Hysterectomy: An International Study.

OBJECTIVES: Laparoendoscopic single-site surgery (LESS) and mini-laparoscopic surgery (Mini-LPS) have been performed with comparable results to conventional laparoscopy. However, there are few data on the comparison between them. Our main objective was to compare LESS and Mini-LPS in terms of surgical time, postoperative pain, and hospital stay in patients who underwent hysterectomy for benign pathology. DESIGN: It is a retrospective international multicentric study carried out in 5 centers including 2 Spanish and 3 Italian. METHODS: Data from patients who underwent hysterectomy for benign pathology between January 1, 2010, and December 31, 2015, were reviewed. We collected the clinical-pathological characteristics of the patients and the perioperative results. The main variables of the study were surgical time, the switch to oral analgesia, and the hospital stay. The two comparison groups in the study included patients undergoing hysterectomy for benign pathology by LESS or by Mini-LPS. The decision to perform the type of procedure was left to the discretion of the surgeon, based primarily on the surgical skills and experience of the center. All data were collected retrospectively by an online encrypted platform. RESULTS: 161 patients were included in the study. 104 (64.6%) patients underwent LESS hysterectomy and 57 (35.4%) Mini-LPS. Median surgical time was significantly longer in the LESS group when compared to the Mini-LPS group (120 vs. 75 min, respectively; p < 0.001). Moreover, longer median hospital stay was observed in the LESS group compared to Mini-LPS (48 vs. 36 h, respectively; p < 0.001). Conversion of the technique to conventional LPS was performed in 4 (2.5%) patients, all of them in the Mini-LPS group (p = 0.015). LIMITATIONS: It is a retrospective study with the biases that this implies. Furthermore, some variables have been incompletely registered in the database, which implies loss of information. This is a nonrandomized study since the decision to intervene with one or another technique was made by the surgeon, which generated 2 nonhomogeneous groups in terms of the number of patients. On the other hand, all the patients who underwent Mini-LPS hysterectomy belonged to the same center, which may have made these results center dependent. CONCLUSIONS: Significant shorter surgical time and shorter hospital stay were observed in patients undergoing Mini-LPS hysterectomy compared to LESS technique; however, intraoperative complications related to instrumentation flaws were higher in the mini-LPS group that required conversion to standard laparoscopy in all cases. Both ultra-minimally invasive techniques seem safe to perform hysterectomies for benign pathology and emphasize the importance in surgical training to adapt them to our current practice.

Accuracy, feasibility and predictive ability of different frailty instruments in an acute geriatric setting.

PURPOSE: To analyze the feasibility, accuracy and the ability of different frailty instruments to predict adverse outcomes. METHODS: A prospective cohort study was conducted in patients ≥ 70 years admitted to the acute care setting (ACS). Feasibility and prevalence of frailty were assessed by FRAIL, Clinical Frailty Scale (CFS), hand grip strength (HGS) and the Spanish Frailty-VIG. Receiver operator characteristic (ROC) curves and area under the curve (AUC) were performed to identify frailty according to each instrument, setting VIG as the reference. For each instrument, multiple logistic regressions were used to examine the effect of frailty on primary outcome (i.e., three-month mortality) and secondary outcomes (i.e., in-hospital mortality, length of stay, institutionalization, functional decline and 30-day readmission). RESULTS: A total of 185 patients were included, with a median age of 89 years. The feasibility of the instruments was 100%, except for HGS (67%). The prevalence of frailty varied from 65.2% (FRAIL) to 86.7% (VIG). AUCs against VIG ranged from 0.69 (95% confidence interval [CI] 0.57-0.81: FRAIL) to 0.77 (95% CI 63.5-90.2: CFS). Frail patients defined by FRAIL were 2.7times more likely to have a prolonged length of stay than non-frail patients (95% CI 1.385-5.416). Three-month mortality occurred more among frail patients, either defined by FRAIL (OR 2.5; 95% CI 1.072-5.881) or CFS (OR 3.7; 95% CI 1.255-10.812), than in non-frail patients. CONCLUSION: The four instruments had high feasibility providing variable prevalence of frailty. FRAIL and CFS predicted well for three-month mortality, and FRAIL also for length of stay. However, none of the instruments predicted for the other secondary outcomes of the study.

In Vivo Complete-Arch Implant Digital Impressions: Comparison of the Precision of Three Optical Impression Systems.

(1) Multiple in vitro studies reported insufficient accuracy of intraoral scanners (IOSs) for complete-arch multiple implant impression. The aim of the study is to analyze the precision of three IOSs, PIC dental (Pic dental, Iditec North West SL), TRIOS 3 (3Shape), and True Definition (Midmark Corporation) and the influence of several factors in the edentulous complete maxillary and mandibular arch. (2) A fully edentulous patient with eight implants in the maxillary and in the mandibular jaw was selected. Five impressions were taken per system and arch. A suprastructure was designed on each digital working cast. The precision was analyzed comparing each of the 28 distances and seven relative angulations of the abutments of all the designed suprastructures. The descriptive statistics, the Student's t-test, and the ANOVA test were used to analyze the data (α = 0.05). (3) Significant differences were observed when comparing the IOSs in some of the distances and angulations. (4) The increase in the distance between implants affected the precision of T and TD but not the PIC system. The type of arch did not affect the PIC precision, but the T and TD systems performed worse in the mandibular arch. The system with the best precision was the PIC, followed by TD, and then T.

Storage Proteins Are Driving Pediatric Hazelnut Allergy in a Lipid Transfer Protein-Rich Area.

Oral food challenge (OFC) remains the gold standard for the diagnosis of food allergies. However, this test is not without risks, given that severe allergic reactions can be triggered while it is conducted. The purpose of this study is to identify potential demographic variables, clinical characteristics of the patients and biomarkers that may be associated with severe reactions during the hazelnut oral challenge test. The sample included 22 children allergic to hazelnut who underwent a tree nut skin prick test (SPT), specific IgE (sIgE) to hazelnut, component-resolved diagnosis (CRD) with different hazelnut allergens (Cor a 1, Cor a 8, Cor a 9, Cor a 11, Cor a 14), and a single-blind placebo-controlled challenge with hazelnut. A statistically significant relationship was found between the severity of the reaction and the highest values of sIgE to hazelnut, Cor a 11 and Cor a 14, cumulative symptom-triggering dose and sunflower seed sensitization. The use of the CRD is a useful tool to identify patients at higher risk of developing a severe reaction. In this pediatric population sample from Spain, storage proteins were confirmed to be most involved in hazelnut allergy and the development of severe reactions.

Evaluation of Cardiotonic Steroid Modulation of Cellular Cholesterol and Phospholipid.

We have previously shown that 21-benzylidene digoxin (21-BD) increases the total cholesterol and phospholipid content on the membrane of HeLa cells. Lipid modulation caused by cardiotonic steroids (CTS) is still unexplored. Therefore, the aim of the present study was to evaluate the cholesterol and phospholipid modulation of the cell membrane caused by ouabain and 21-BD and the possible involvement of the caveolae on this modulation. For this, one cell line containing caveolae (HeLa) and other not containing (Caco-2) were used. The modulation of the lipid profile was evaluated by total cholesterol and phospholipids measurements, and identification of membrane phospholipids by HPTLC. The cholesterol distribution was evaluated by filipin staining. The caveolin-1 expression was evaluated by Western Blotting. Ouabain had no effect on the total membrane lipid content in both cell lines. However, 21-BD increased total membrane phospholipid content and had no effect on the membrane cholesterol content in Caco-2 cells. CTS were not able to alter the specific phospholipids content. In the filipin experiments, 21-BD provoked a remarkable redistribution of cholesterol to the perinuclear region of HeLa cells. In Caco-2 cells, it was observed only a slight increase in cholesterol, especially as intracellular vesicles. The caveolin-1 expression was not altered by any of the compounds. Our data mainly show different effects of two cardiotonic steroids. Ouabain had no effect on the lipid profile of cells, whereas 21-BD causes important changes in cholesterol and phospholipid content. Therefore, the modulation of cholesterol content in the plasma membrane of HeLa cells is not correlated with the expression of caveolin-1.

Adhesion pathway proteins and risk of atrial fibrillation in the Multi-Ethnic Study of Atherosclerosis.

BACKGROUND: The cellular adhesion pathway has been suggested as playing an important role in the pathogenesis of atrial fibrillation (AF). However, prior studies that have investigated the role of adhesion pathway proteins in risk of AF have been limited in the number of proteins that were studied and in the ethnic and racial diversity of the study population. Therefore we aimed to study the associations of fifteen adhesion pathway proteins with incident AF in a large, diverse population. METHODS: Multi-Ethnic Study of Atherosclerosis participants from four races/ethnicities (n = 2504) with protein levels measured were followed for incident AF (n = 253). HGF protein was measured on Exam 1 samples (N = 6669; AF n = 851). Cox proportional hazards regression was used to assess the association of AF with 15 adhesion pathway proteins. Bonferroni correction was applied to account for multiple comparisons. RESULTS: After adjusting for potential confounding variables (age, sex, race/ethnicity, height, body mass index, systolic blood pressure, antihypertension therapy, diabetes status, current smoker, current alcohol use, and total and HDL cholesterol), and accounting for multiple testing (P < 0.05/15 = 0.0033), circulating levels of the following proteins were positively associated with a higher risk of AF: MMP-2 (HR per standard deviation increment, 1.27; 95% CI 1.11‒1.45), TIMP-2 (HR 1.28; 95% CI 1.12‒1.46), VCAM-1 (HR 1.32; 95% CI 1.16‒1.50), and SLPI (HR 1.22; 95% CI 1.07‒1.38). The association between proteins and AF did not differ by race/ethnicity. CONCLUSIONS: Circulating levels of MMP-2, TIMP-2, VCAM-1, and SLPI were positively associated with an increased risk of incident AF in a diverse population. Our findings suggest that adhesion pathway proteins may be important risk predictors of AF.
