AimsTo evaluate the efficacy of methotrexate (MTX) in preventing the recurrence of acute anterior uveitis (AAU).MethodsThis prospective, open, longitudinal study included patients from June 2002 to March 2005 who had either three or more episodes of AAU in the previous year, or a recurrence of AAU within 3 months before starting the trial. We excluded uveitis of infectious origin, masquerade syndromes, and patients with contraindications to MTX. The response criteria were defined as an absence of symptoms and the presence of a normal ophthalmologic examination. The study outcome compared the number of flare-ups of uveitis over an MTX-treated for 1 year to the number of flare-ups of the same group during the previous year without MTX.ResultsA total of 571 patients with uveitis were evaluated during the period of the study, and 10 fulfilled the inclusion criteria. One patient refused the treatment, and nine completed the study. The mean number of recurrences in the pre-MTX year was 3.4 (SD: 0.52), which was significantly reduced to 0.89 (SD: 1.17) in the year of treatment (P=0.011).ConclusionMTX treatment seems to reduce the number of flare-ups in patients with recurrent AAU.Eye (2009) 23, 1130–1133; doi:10.1038/eye.2008.198; published online 8 August 2008 [ABSTRACT FROM AUTHOR]

Introduction: Systemic lupus erythematosus (SLE) in children usually follows a more severe course than in adults, but sometimes in the previous studies reported there are many confounding factors. Objective: To analyse the immunological and clinical characteristics of SLE juvenile onset and SLE adult onset. Methods: We studied 179 patients with SLE, 49 patients were aged 6–18 yrs at onset of disease. Anti-dsDNA antibodies were detected by radioimmunoassay and antibodies to extractable nuclear antigens (ENA): anti-nRNP, anti-Sm, anti-Ro/SS-A and anti-La/SS-B antibodies by ELISA, counterimmuno-electrophoresis and immunoblotting. Results: Juvenile-onset SLE shows a higher frequency of cutaneous vasculitis (44.8% vs 27.6%; P<0.05), seizures (18.3% vs 7.6%; P<0.05) nephropathy (67.3% vs 48.4%; P<0.025), and discoid lupus erythematosus (26.5% vs 13.8%; P<0.05). The incidence of articular manifestations is lower than in adults (85.7% vs 96.1%; P<0.025). No significant differences were found between the two groups in relation with the prevalence of antinuclear antibodies. Conclusions: Juvenile-onset SLE has more frequent neurological and renal manifestations than adult-onset SLE, but immunological markers are similar in both groups. These features suggest the most severe clinical manifestations in the juvenile-onset SLE group are not related with the presence of studied antibodies by different methods. [ABSTRACT FROM AUTHOR]

Introduction: Medical prescriptions have traditionally been focused on aerobic exercise. However, an increasing number of authors are pointing towards strength training as the healthiest exercise modality. The purpose of this study is to assess whether physicians increase their knowledge as well as their confidence to prescribe strength training after attending a physical training course., Materials and Methods: A prospective cohort study of 160 physicians was conducted, 80 physicians out of the 160 attended a physical training course, whereas the remaining 80 physicians did not. Personal and professional data was collected, as well as data regarding the type of exercise they were practising or prescribing and the confidence and knowledge for their prescription. Finally, differences between the two groups and the impact of attending the course where analysed., Results: Both groups were homogeneous in gender, age, medical speciality and practice of physical exercise, with very low rates of strength training and prescription for both groups. It was established that the group attending the course acquired knowledge and confidence for prescribing strength training. Moreover, this group considered that strength training was the exercise modality which should be encouraged (P<.001)., Conclusions: Education in strength training for physicians by means of a theoretical-practical course increases knowledge and confidence for its prescription., (Copyright © 2021 Sociedad Española de Rehabilitación y Medicina Física.

Bovine paratuberculosis (PTB) is an infectious disease that affects ruminants worldwide and is a burden on the dairy industry. PTB control measures include culling of Mycobacterium avium subsp. paratuberculosis (MAP)-infected animals from the herd and the enhancement of farm-biosecurity measures. Diagnostics tools for the direct detection of MAP are fecal real-time qPCR and bacteriological culture, the last one being considered the gold standard. However, both show limitations for detecting subclinical MAP-infected cattle with low bacterial load in feces and gut tissues. Droplet digital polymerase chain reaction (ddPCR) is a third-generation PCR method that shows high reproducibility for the quantification of low DNA copy numbers. The objective of this study was to design a ddPCR assay to detect and quantify a fragment of the F57 MAP-specific sequence in samples of naturally MAP-infected Holstein cattle. DNA was isolated from whole-blood and fecal samples from control cows with a negative ELISA and qPCR result ( N = 75) and from cows with PTB-associated focal ( N = 32), multifocal ( N = 21), and diffuse lesions ( N = 17) in gut tissues. After ddPCR, the DNA extracted from fecal samples of cows with diffuse lesions showed higher mean copies per microliter (13,791.2 copies/μl) than samples from cows with multifocal lesions (78.8 copies/μl), focal lesions (177.1 copies/μl) or control cows (4.8 copies/μl) ( P ≤ 0.05). Significant differences in mean DNA copies/μl were also observed in the blood samples from cows with focal lesions (47.7 copies/μl) when compared with cows with multifocal and diffuse lesions; 18.1 and 12.4 copies/μl, respectively. Using a principal component analysis, the results of the fecal ddPCR clustered together with the results of a commercial ELISA for the specific detection of MAP antibodies, fecal and tissue qPCR, and bacteriological culture results. In contrast, blood ddPCR results clustered together with the results of an ELISA for the detection of a biomarker of subclinical PTB, the ABCA13 transporter. Blood ddPCR was the most sensitive tool (sensitivity 71%, specificity 100%) of all the quantitative methods used in the study for the detection of subclinical cows with focal lesions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Badia-Bringué, Canive, Casais, Blanco-Vázquez, Amado, Iglesias, González, Bascones, Juste and Alonso-Hearn.)

Objective: Post-COVID syndrome can impact against every sphere of daily live. The objective of this work was to detect the factors correlated with a better or worse physical recovery four months after hospital discharge from a hospitalization in ICU due to COVID-19., Methods: Prospective descriptive study of 125 patients valued by the Rehabilitation Service during hospitalization in ICU, from March 12 th to December 31 st , 2020. Data from 76 patients was analysed with clinical follow up after 1, 2 and 4 months of hospital discharge. Variables on personal, hospitalary, functional symptoms/signals and physical recovery were analysed with mean ± standard deviation, counting (percentage), T-student test and Fisher test., Results: After one month, fatigue was observed in 60 (80%) patients and dyspnoea in 47 (62%). After two months, fatigue in 37 (55%), dyspnoea in 25 (33%), shoulder pain in 33 (43%), average QuickDASH was 22.7 (11.3-50), Sit-to-Stand Test in 30 seconds 11.5 (10-13) and 6-minute walk test 390 meters (326-445). In the fourth month, 25 (53%) had returned to work and had an average of the physical recovery of 79.1%±18.3%. There was no correlation between physical recovery ≥75% and the first month data, but there certainly was a correlation between some second month variables, such as fatigue (p=0.001), dyspnoea (p=0.035), QuickDASH (p=0.001) and 6-minute walk test (p=0.021)., Conclusions: Symptoms (fatigue and dyspnoea) and functional scales (QuickDASH and 6-minute walk test) after 2 months predict a better/worsen physical recovery after 4 months of hospital discharge., Competing Interests: Disclosure The authors report no conflicts of interest in this work.

Objective: The aim of this study was to analyse both the impact of the pandemic and clinical and teaching organisation in Spanish Physical Medicine and Rehabilitation Departments during the COVID-19 pandemic., Methods: A survey was conducted of the tutors of rehabilitation departments. The questionnaire contained 31 questions divided into 6 parts about the following: general information on the department, adaptation of rehabilitation departments to the COVID pandemic, clinical work of rehabilitation physicians, the approach to rehabilitation in COVID patients, and the effects of the pandemic on the health and teaching activity of rehabilitation physicians during this period., Results: A total of 54 responses were obtained. Almost half of the departments cancelled face-to-face medical consultations (40%) and 48% of the treatment rooms were turned into COVID beds. In 30 hospitals (55.6%), the physicians worked in COVID units. Most of the rehabilitation departments developed both graphic and audiovisual material with exercises, referral protocols and guidelines for the rehabilitation management and treatment of COVID 19 patients. Half of the departments reported some anxiety symptoms in medical staff. Tutorial work has been cancelled (40.7%) or reduced (35.2%)., Conclusions: The organisation of Spanish rehabilitation departments in response to the COVID pandemic has been very similar throughout the country. The response of these departments to the healthcare crisis has revealed the versatility of rehabilitation physicians., (Copyright © 2020 Sociedad Española de Rehabilitación y Medicina Física.

Neuropathic pain impairs quality of life in affected individuals and poses a challenge to clinicians due to the complexity of its treatment and frequent therapeutic failures. We present 4clinical cases of chronic neuropathic pain (LANSS ≥ 19), refractory to conservative treatment (meralgia paraesthetica, post-surgical pain and 2surgical scars). Subcutaneous botulinum toxin type A was infiltrated periodically over the painful area. All patients experienced subjective improvement in pain and improvement measured by the visual analogic scale. Pain relief started at 5-21 days and continued up to 1.5-3 months, and up to 9 months in one patient. Pain that reappeared was of lower intensity in 3patients and was reduced in area in 2patients., (Copyright © 2019 Sociedad Española de Rehabilitación y Medicina Física.

Introduction: Lipoedema is a chronic disorder of adipose tissue, characterised by disproportionate fat deposits in the lower limbs and pain with preservation of the feet. The condition usually only affects women. Diagnosis is clinical and mainly by exclusion. This disorder is little known and underdiagnosed. The objective of this article was to perform a non-systematic review of the literature on lipoedema, its diagnostic criteria and proposed treatments., Methodology: A literature search was carried out from January 2012 to January 2018, in the following databases: Pubmed, Scopus, Medline, Web of Science and CINAHL., Selection of Studies: A total of 12 articles were included, of which 10 were reviews, one was a cross-sectional study and another was a case series., Conclusions: Diagnosis of lipoedema is mainly clinical and through exclusion of other disorders. There is no consensus on its treatment, but treatment focuses on attempting to minimise symptoms and prevent disease progression and the disability it may generate., (Copyright © 2018 Elsevier España, S.L.U. y SERMEF.

Background: The increasing incidence of osteoporotic hip fracture (HF) has raised the requirements of red blood cell (RBC) transfusions, whereas this scarce resource may cause morbidity and mortality., Study Design and Methods: This study was a multicenter, randomized, double-blind, clinical trial that aimed to assess efficacy of ferric carboxymaltose (FCM) with or without erythropoietin (EPO) in reducing RBC transfusion in the perioperative period of HF. Participants (patients > 65 years admitted with HF and hemoglobin [Hb] levels of 90-120 g/L) were randomly assigned to receive a preoperative single dose of 1 g of FCM (short intravenous [IV] infusion over 15 min), plus 40,000 IU of subcutaneous EPO (EPOFE arm); versus 1 g of IV FCM plus subcutaneous placebo (FE arm); and versus IV and subcutaneous placebo (placebo arm). Primary endpoint was the percentage of patients who received RBC transfusion, and secondary endpoints were the number of RBC transfusions per patient, survival, hemoglobinemia, and health-related quality of life (HRQoL; by means of Short Form 36 Version 2 questionnaire)., Results: A total of 306 patients (85% women, mean age 83 ± 6.5 years) were included. A total of 52, 51.5, and 54% of patients required RBC transfusion in the EPOFE, FE, and placebo arms, respectively, with no significant differences in the number of RBC transfusions per patient, survival, HRQoL, and adverse events among treatment groups. A significant increase in Hb levels was achieved at discharge (102 g/L vs. 97 g/L) and 60 days after discharge (125 g/L vs. 119 g/L) in the EPOFE arm with respect to placebo arm; in addition, a higher rate of patients recovered from anemia in the EPOFE arm with respect to the placebo arm (52% vs. 39%), 60 days after discharge., Conclusion: Preoperative treatment with FCM alone or in combination with EPO improved recovery from postoperative anemia, but did not reduce the needs of RBC transfusion in patients with HF., (© 2016 AABB.)

Native cellulose, lignocellulosic materials from Brazil (carnauba palm leaves and macauba pulp and shell) and pine nut shell from Spain have been studied as substrates for the production of HMF and furfural in a conventional microwave oven. In order to promote the dissolution of native cellulose, several ionic liquids, catalysts, organic solvents and water doses have been assessed. The most suitable mixture (5mL of choline chloride/oxalic acid, 2mL of sulfolane, 2mL of water, 0.02g of TiO2 and 0.1g of substrate) has been chosen to conduct kinetic studies at different reaction times (5-60min) and various temperatures (120-200°C) and to evaluate the best conditions for HMF+furfural production according to Seaman's model. The best production yields of HMF+furfural have been attained for native cellulose, with a yield of 53.24% when an ultrasonic pretreatment was used prior to a microwave treatment with stirring., (Copyright © 2014 Elsevier Ltd.

Background: Active compression-decompression cardiopulmonary resuscitation (ACDR CPR) uses a hand-held suction device, applied mid-sternum, to compress the chest then actively decompress the chest after each compression. Randomised controlled trials testing this device have shown discordant results., Objectives: To determine the effect of active chest compression-decompression CPR compared to standard chest compression CPR on mortality and neurological function in adults with cardiac arrest treated either in-hospital or out-of-hospital., Search Methods: We updated the searches of CENTRAL in The Cochrane Library (Issue 12 of 12, 2012), MEDLINE (OVID, 1946 to January week 1 2013), and EMBASE (OVID, 1980 to week 1 2013) on 14 January 2013. We checked the reference list of retrieved articles, contacted experts in the field, and searched ClinicalTrials.gov., Selection Criteria: All randomised or quasi-randomised studies comparing active compression-decompression with standard manual chest compression in adults with a cardiac arrest who received cardiopulmonary resuscitation by a trained medical or paramedical team., Data Collection and Analysis: We independently extracted data on an intention-to-treat basis. When needed, we contacted the authors of the primary studies. If appropriate, we cumulated studies and pooled relative risk (RR) estimates. We predefined subgroup analyses according to setting (out-of-hospital or in-hospital) and attending team composition (with physician or paramedic only)., Main Results: In this update, 27 new related publications were found, but they did not all fulfil inclusion criteria or concerned participants already reported in previous publications. In the end, we included 10 trials in this review: Eight were in out-of-hospital settings; one was set in-hospital only; and one had both in-hospital and out-of-hospital components. Allocation concealment was adequate in four studies. The two in-hospital studies were different in quality and size (773 and 53 participants). Both found no differences between ACDR CPR and STR in any outcome.Out-of-hospital trials cumulated 4162 participants. There were no differences between ACDR CPR and STR for mortality either immediately (RR 0.98, 95% confidence interval (CI) 0.94 to 1.03) or at hospital discharge (RR 0.99, 95% CI 0.98 to 1.01). The pooled RR of neurological impairment of any severity was 1.71 (95% CI 0.90 to 3.25), with a non-significant trend to more frequent severe neurological damage in survivors of ACDR CPR (RR 3.11, 95% CI 0.98 to 9.83). However, assessment of neurological outcome was limited, and few participants had neurological damage.There was no difference between ACDR CPR and STR with regard to complications such as rib or sternal fractures, pneumothorax, or haemothorax (RR 1.09, 95% CI 0.86 to 1.38). Skin trauma and ecchymosis were more frequent with ACDR CPR., Authors' Conclusions: Active chest compression-decompression in people with cardiac arrest is not associated with any clear benefit.

Background: Around one third to one half of patients with hip fractures require red-cell pack transfusion. The increasing incidence of hip fracture has also raised the need for this scarce resource. Additionally, red-cell pack transfusions are not without complications which may involve excessive morbidity and mortality. This makes it necessary to develop blood-saving strategies. Our objective was to assess safety, efficacy, and cost-effictveness of combined treatment of i.v. ferric carboxymaltose and erythropoietin (EPOFE arm) versus i.v. ferric carboxymaltose (FE arm) versus a placebo (PLACEBO arm) in reducing the percentage of patients who receive blood transfusions, as well as mortality in the perioperative period of hip fracture intervention., Methods/design: Multicentric, phase III, randomized, controlled, double blinded, parallel groups clinical trial. Patients > 65 years admitted to hospital with a hip fracture will be eligible to participate. Patients will be treated with either a single dosage of i.v. ferric carboxymaltose of 1 g and subcutaneous erythropoietin (40.000 IU), or i.v. ferric carboxymaltose and subcutaneous placebo, or i.v. placebo and subcutaneous placebo. Follow-up will be performed until 60 days after discharge, assessing transfusion needs, morbidity, mortality, safety, costs, and health-related quality of life. Intention to treat, as well as per protocol, and incremental cost-effectiveness analysis will be performed. The number of recruited patients per arm is set at 102, a total of 306 patients., Discussion: We think that this trial will contribute to the knowledge about the safety and efficacy of ferric carboxymaltose with/without erythropoietin in preventing red-cell pack transfusions in patients with hip fracture.

Objective: To identify characteristics of early arthritis units, that may be associated with better referral eficiency., Methods: A national survey of the 36 early arthritis units (EAU) in Spanish Rheumatology Units in 2004 (SERAP project). Survey collected information about general practitioners (GP) educational program to improve knowledge and practical skills of early arthritis, networking and feed-back system and referral efficiency. EAU were classified in two groups according to 25 and 50% of inappropriate referral process, respectively., Results: Thirty four of the 36 (94%) EAU, answered the survey. GP were trained in only 1 medical meeting in the primary care clinic, with one or more rheumatologists responsible of GP education. Fourteen of the 34 EAU (42.4%) regularly interacted with GP and only 20 (39.4%) contacted the GP who were responsible for the wrong referral process. Median lag time for referral to the Rheumatology out-patient clinic, was 73 days (15-365 days). The percentage of wrongly referred patients was between 0 and 80% (38% ± 21). Only 10 EAU (27.8%) referred patients appropriately according to the most strict criteria (25% of inappropriate referral) and 27 EAU (75%), according to 50% of inappropriate referral criteria., Conclusions: Only two aspects of the EAU implementation strategy were associated with better referral efficiency: 1) interaction with the GP responsible of the inappropriate referral process and 2) a lower median lag time for referral to the Rheumatology out-patient clinic., (2010 Elsevier España, S.L.

Objective: To compare the concept of patient with pluripathology (PP) with the index of comorbidity of Charlson (IC) respect to the resources use and prognosis of hospitalized patients., Patients and Methods: An observational prospective study of 207 consecutively hospitalized patients in an internal medicine unit was conducted. The PP, a variant of PP with three or more criteria (PP3), IC and IC fit to the age (ICE) were determined, and their relation with the consumption of resources (emergency attentions, programmed consultations of specialties and episodes of hospitalization in the last year, length of stay, own procedures, other specialty procedures and consulting) and prognosis (hospital mortality, significant functional deterioration and rehospitalization) were stayed., Results: The frequency of PP and PP3 was 40.6 and 16.9%, respectively. The median of the IC and ICE score were 2 (0-7) and 4 (0-11), respectively. We found the following independent relations: IC of 3 or greater with the rehospitalization and the length of stay; ICE of 5 or greater with mortality; PP3 with mortality, rehospitalization and emergency visits, hospitalizations and consultations in the last year; the categories B and F of PP with hospitalizations in the last year; the category D of PP with consultations in the last year; and the association of categories A, B and C with mortality and hospitalizations in the last year. PP was not related in an independent form with any variable., Conclusion: The IC and the concept of PP do not identify the same hospitalized patient population. Modifications of the PP definition, like PP3, or the analysis of the different clinical categories of PP and their associations, could improve the utility of this concept.
