RESUMO

BACKGROUND AND OBJECTIVE: The aim was assessing a short training for healthcare providers on patient-focused counselling to treat childhood obesity in primary care, along with dietitian-led workshops and educational materials. METHODS: Randomized clustered trial conducted with paediatrician-nurse pairs (Basic Care Units [BCU]) in primary care centres from Tarragona (Spain). BCUs were randomized to intervention (MI) (motivational interview, dietitian-led education, and educational materials) or control group (SC, standard care). Participants were 8-14-year-old children with obesity, undergoing 1-11 monthly treatment visits during 1 year at primary care centres. The primary outcome was BMI z-score reduction. RESULTS: The study included 44 clusters (23 MI). Out of 303 allocated children, 201 (n = 106 MI) completed baseline, final visits, and at least one treatment visit and were included in the analysis. BMI z-score reduction was -0.27 (±0.31) in SC, versus -0.36 (±0.35) in MI (p = 0.036). Mixed models with centres as random effects showed greater reductions in BMI in MI than SC; differences were B = -0.11 (95% CI: -0.20, -0.01, p = 0.025) for BMI z-score, and B = -2.06 (95% CI: -3.89, -0.23, p = 0.028) for BMI %. No severe adverse events related to the study were notified. CONCLUSION: Training primary care professionals on motivational interviewing supported by dietitians and educational materials, enhanced the efficacy of childhood obesity therapy.

RESUMO

BACKGROUND AND AIMS: Oxaliplatin (OX) has been described as a potential etiologic agent for porto-sinusoidal vascular disorder (PSVD). Our aim was to describe the natural history of PSVD due to OX in colon cancer (CRC) and identify risk factors for its development. METHODS: We made a multicenter retrospective case-control (ratio 1:3) study with patients diagnosed of PSVD-OX. Baseline data, end of treatment, years of follow-up and diagnosis of PSVD were collected and compared to controls (without PSVD). Besides, 16 different SNPs were selected from bibliography and analyzed by genotyping in the case group to identify potential genetic risk factors. RESULTS: 41 cases were identified, with a median time to PSVD diagnosis after the end of OX of 34 months. Spleen diameter was the strongest predictor of PSVD during treatment (OR 43.94 (14.48-133.336); p < 0.0001). Additionally, thrombocytopenia (<150 × 10^9) at one year was a significant disease risk marker (OR 9.35; 95% CI: 3.71-23.58; p = 0.001). We could not establish any significant association between the selected SNPs and PSVD diagnosis. CONCLUSION: The increase of spleen diameter is the strongest predictor of PSVD in patients treated with OX for CRC. These patients could be candidates for a specific follow-up of portal hypertension-related complications.

RESUMO

Objectives: Radiation-induced dermatitis (RD) is one of the most common toxicities in radiation therapy (RT) patients. Corticosteroids, immunosuppressants, and natural products (NPs) have been used as treatment. The objective was to evaluate the efficacy of a NPs-based cream (Alantel®) to reduce the incidence of RD in women with breast cancer undergoing RT treatment. Design: We conducted a controlled, randomized, double-blind clinical trial. Setting: Radiation Oncology Unit of the Reina Sofía Hospital and 5 Primary Care centers of the Cordoba and Guadalquivir Health District (Spain). Interventions: Patients assigned to the experimental group (GTA) were treated with Alantel, while those in the control group (GTE) were treated with a moisturizer and emollient cream. Main outcome measures: The primary outcome variable was the incidence of RD. RD-free time, duration of RD, quality of life, and product safety were also assessed. Results: Seventy patients were included in the study, 35 in the GTA and 35 in the GTE. The incidence of RD was lower in the GTA (71.4%) than in the GTE (91.4%) after 4 weeks of follow-up (RR = 0.78; NNT = 5; p < 0.031). The Skindex-29 questionnaire showed differences in the statement: "My skin condition makes it hard to work or do hobbies" (17.1% in the GTE vs. 2.9% in GTA; p = 0.024). Conclusions: The higher efficacy of Alantel® compared to the control cream in reducing the incidence of RD in women with breast cancer has been demonstrated.

RESUMO

INTRODUCTION: Post-stroke fatigue (PSF) has been described as early exhaustion with tiredness that develops during physical or mental activity and generally does not improve with rest. There are inconsistent findings on the relationship between the characteristics of the ischemic brain lesion and PSF. However, some studies suggest that specific neuroanatomical and neuroplastic changes could explain post-stroke fatigue. The aim was to evaluate the severity of PSF in relation to the location and the size of the ischemic lesion in acute stroke patients to establish possible predictors of PSF. PATIENTS AND METHODS: We performed a prospective observational study to establish potential early predictors of long-term PSF, which was assessed using the Fatigue Assessment Scale six months after ischemic stroke. After segmenting brain infarcts on Diffusion-Weighted Imaging (DWI) images, we studied the association with PSF using Voxel-Based Lesion-Symptom Mapping (VLSM). RESULTS: Out of 104 patients, 61 (59 %) reported PSF. Female sex and history of diabetes mellitus were associated with a greater risk of developing PSF. The association of PSF with female sex was confirmed in a replication cohort of 50 patients. The ischemic lesion volume was not associated with PSF, and VBLSM analysis did not identify any specific brain area significantly associated with PSF. CONCLUSIONS: PSF is frequent in stroke patients, especially women, even after six months. The absence of neuroanatomical correlates of PSF suggests that it is a multifactorial process with biological, psychological, and social risk factors that require further study.

RESUMO

Carbapenem-resistant Klebsiella pneumoniae (CR-KP) are a public health concern, causing infections with a high mortality rate, limited therapeutic options and challenging infection control strategies. In Portugal, the CR-KP rate has increased sharply, but the factors associated with this increase are poorly explored. In order to address this question, phylogenetic and resistome analysis were used to compare the draft genomes of 200 CR-KP isolates collected in 2017-2019 from five hospitals in the Lisbon region, Portugal. Most CR-KP belonged to sequence type (ST) 13 (29%), ST17 (15%), ST348 (13%), ST231 (12%) and ST147 (7%). Carbapenem resistance was conferred mostly by the presence of KPC-3 (74%) or OXA-181 (18%), which were associated with IncF/IncN and IncX plasmids, respectively. Almost all isolates were multi-drug resistant, harbouring resistance determinants to aminoglycosides, beta-lactams, trimethoprim, fosfomycin, quinolones and sulphonamides. In addition, 11% of isolates were resistant to colistin. Colonizing and infecting isolates were highly related, and most colonized patients (89%) reported a previous hospitalization. Moreover, among the 171 events of cross-dissemination identified by core genome multi-locus sequence typing data analysis (fewer than five allelic differences), 41 occurred between different hospitals and 130 occurred within the same hospital. The results suggest that CR-KP dissemination in the Lisbon region results from acquisition of carbapenemases in mobile genetic elements, influx of CR-KP into the hospitals by colonized ambulatory patients, and transmission of CR-KP within and between hospitals. Prudent use of carbapenems, patient screening at hospital entry, and improvement of infection control are needed to decrease the burden of CR-KP infection in Portugal.

RESUMO

Candida auris is a multidrug-resistant pathogen yeast that produces nosocomial outbreaks, due to its ability in colonizing the skin, mucous membranes and surfaces. Rapid diagnosis is essential to control its spread. The aim of this study was to compare the Eazyplex® Candida auris kit (AmplexDiagnostics GmbH) for the rapid identification of patients colonized with C. auris, with the reference method used in our institution (culture and identification by MALDI-TOF). This easy-to-perform test allows obtaining a fast result, in ~30 min. First, we achieved a preliminary study from previously characterized Candida species colonies obtained from 51 clinical samples, with 100% agreement between culture isolation and the Eazyplex® Candida auris LAMP. Second, 152 epidemiological surveillance samples (pharyngeal and axillary-rectal swabs) were tested retrospectively. The sensitivity, specificity, positive and negative predictive values were 91.8%, 98.8%, 98.2% and 94.5%, respectively. Eazyplex® Candida auris showed acceptable results compared with culture in detecting C. auris from surveillance samples with the advantage of single-test and shorter time for handling and result than culture, in addition to its great specificity, positive and negative predictive values.

RESUMO

Objetivos Evaluar la frecuencia de las admisiones en los servicios de urgencias (ASU) por ambulatory care sensitive conditions (ACSC) y no-ACSC de personas que viven en residencias; describir y comparar sus características, y analizar los costes asociados. Método Este estudio multicéntrico, retrospectivo y observacional evaluó 2.444ASU de personas ≥65 años que viven en residencias en 5 servicios de urgencias de Cataluña por ACSC y no-ACSC, en 2017. Se recogieron variables sociodemográficas, estado funcional y cognitivo, e información sobre diagnóstico y hospitalización. Se evaluaron los costes relacionados con ACSC-ASU y se efectuó un análisis de sensibilidad utilizando diferentes supuestos de disminución de ingresos por ACSC. Resultados La media de edad de la muestra del estudio fue de 85,9 años (desviación estándar: 7,2 años). La frecuencia de ACSC-ASU y no-ACSC-ASU fue del 56,6 y el 43,4%, respectivamente. El 56,6 y el 78% presentaban dependencia severa y deterioro cognitivo, respectivamente, sin observarse diferencias entre los 2 grupos. Las 3 ACSC más frecuentes fueron caídas/traumatismos (13,8%), enfermedad pulmonar obstructiva crónica/asma (11,4%) e infección urinaria (7,4%). El coste medio por ACSC-ASU fue de 1.408,24€. Suponiendo una reducción del 60% de las ACSC-ASU, el ahorro de costes estimado sería de 1,2 millones de euros. Conclusiones Las admisiones en urgencias por ACSC procedentes de entornos residenciales suponen un impacto significativo tanto en la frecuencia como en los costes. La disminución de estas enfermedades mediante la aplicación de intervenciones específicas podría redirigir los costes evitados hacia la mejora del apoyo asistencial en los entornos residenciales (AU)


Objectives To assess the frequency of emergency department admissions (EDAs) for ambulatory care sensitive conditions (ACSC) and non-ACSC among older adults living in care homes (CH), to describe and compare their demographic and clinical characteristics, the outcomes of the hospitalization process and the associated costs. Method This multicenter, retrospective and observational study evaluated 2444 EDAs of older adults ≥65 years old living in care homes in five emergency departments in Catalonia (Spain) by ACSC and non-ACSC, in 2017. Sociodemographic variables, prior functional and cognitive status, and information on diagnosis and hospitalization were collected. Additionally, the costs related with the EDAs were calculated, as well as a sensitivity analysis using different assumptions of decreased admissions due to ACSC Results A total of 2444 ED admissions were analyzed. The patients’ mean (SD) age was 85.9 (7.2) years. The frequency of ACSC-EDA and non-ACSC-EDA was 56.6% and 43.4%, respectively. Severe dependency and cognitive impairment were present in 56.6% and 78%, respectively, with no differences between the two groups. The three most frequent ACSC were falls/trauma (13.8%), chronic obstructive pulmonary disease/asthma (11.4%) and urinary tract infection (7.4%). The average cost per ACSC-EDA was €1408.24. Assuming a 60% reduction of ACSC-EDA, the estimated cost savings would be €1.2 million. Conclusions Emergency admissions for ACSC from care homes have a significant impact on both frequency and costs. Reducing these conditions through targeted interventions could redirect the avoided costs toward improving care support in residential settings (AU)

RESUMO

BACKGROUND: Workplace aggressions on hospital workers is a very frequent and under-reported problem. OBJECTIVE: The novel objective of our study was to analyze the number of workplace aggressions per hospital worker. Other objectives of the study were to analyze the management knowledge and interest in receiving training on aggressions by hospital workers. METHODS: An anonymous survey was handed out among all professionals in a university hospital. RESULTS: A total of 1118 anonymous surveys were collected. The responders declared that throughout their working life they had suffered some sort of verbal aggression in the hospital in 766 cases (68.5%) and physical aggression in 393 cases (35.2%). Multiple logistic regression analyses found higher risk of receiving physical and verbal aggression in the nursing category and in the Emergency, Critical Care or Psychiatry Units, and a higher risk of receiving physical aggression in women. The score on the level of personal knowledge regarding the legal, physical, and psychological management of aggressions (score 0-10 for each of the 3 aspects) was 2.91±2.68 in legal management, 2.97±2.77 in psychological management and 2.91±2.76 in physical management. The opinion about the interest of receiving training (score from 0 to 10) on the legal management of hospital aggressions was 8.90±1.72, on psychological management was 8.85±1.78 and on physical management was 8.88±1.78. CONCLUSIONS: Workplace aggression on hospital workers mainly affects women, the nursing category and the Emergency, Critical Care or Psychiatry Units. Hospital workers showed little knowledge on the topic but a great interest in receiving training.

RESUMO

One of the pillars of the geometric approach to networks has been the development of model-based mapping tools that embed real networks in its latent geometry. In particular, the tool Mercator embeds networks into the hyperbolic plane. However, some real networks are better described by the multidimensional formulation of the underlying geometric model. Here, we introduce D-Mercator, a model-based embedding method that produces multidimensional maps of real networks into the (D + 1)-hyperbolic space, where the similarity subspace is represented as a D-sphere. We used D-Mercator to produce multidimensional hyperbolic maps of real networks and estimated their intrinsic dimensionality in terms of navigability and community structure. Multidimensional representations of real networks are instrumental in the identification of factors that determine connectivity and in elucidating fundamental issues that hinge on dimensionality, such as the presence of universality in critical behavior.

RESUMO

Sheep are very well adapted to changing environments and are able to produce and reproduce with low inputs in feed and water better than other domestic ruminants. Indeed, the ewe body condition score (BCS) and live weight (LW) play a significant role in productive and reproductive performance. This work conducts a genome-wide association study (GWAS) to detect genetic variants associated with growth traits in 225 adult ewes of the Rasa Aragonesa breed by using the genotypes from 50 k and HD Illumina Ovine BeadChip. These ewes were measured for LW, BCS and growth rate (GR) for 2 years, from January to September. Corrected phenotypes for BCS, LW and GR were estimated and used as input for the GWAS. Only one single nucleotide polymorphism (SNP) rs425509273 in chromosome 9 (OAR9), associated with the GR, overcame the genome-wise significance level. One, three and nine SNPs were associated at the chromosome-wise level (FDR 10%) for traits BCS, LW and GR, respectively. The cytochrome P450 family 7 subfamily B member 1 (CYP7B1) candidate gene, located 83 kb upstream from SNP rs425509273 in OAR9, was partially isolated and Sanger-sequenced. Fifteen polymorphisms comprising 12 SNPs, two indels and one polyC, were detected in promoter, exon 1, 3, 5, and intron 1-3 region. The SNP association analysis of the polymorphisms located close to the transcription start site (TSS) showed that a 22 bp insertion located at -58 nucleotides from the TSS (indel (-58)), a polyC (-25), and two A/G SNPs (SNP3 (-114) and SNP5 (-63)) were associated with the GR trait, whereas only the indel (-58) was associated with the BCS trait. The haplotype analysis confirmed these results. The functional characterisation of the polymorphisms at CYP7B1 gene in liver by real-time quantitative PCR analysis confirmed that the mutations in the promoter region affected CYP7B1 gene expression. Our results demonstrated the involvement of the CYP7B1 gene promoter on GR and BCS traits in Rasa Aragonesa. These findings suggest that variations in ovine CYP7B1 may serve as potential genetic markers to be used in breeding programmes to improve growth characteristics that could influence reproductive traits.

RESUMO

BACKGROUND: Interferon-y Release Assays (IGRA) reversions have been reported in different clinical scenarios for the diagnosis of tuberculosis (TB) infection. This study aimed to determine the rate of QuantiFERON-TB Gold Plus (QFT-Plus) reversions during contact investigation as a potential strategy to reduce the number of preventive treatments. METHODS: Prospective, multicentre cohort study of immunocompetent adult contacts of patients with pulmonary TB tested with QFT-Plus. Contacts with an initial positive QFT-Plus (QFT-i) underwent a second test within 4 weeks (QFT-1), and if negative, underwent a repeat test 4 weeks later (QFT-2). Based on the QFT-2 result, we classified cases as sustained reversion if they remained negative and as temporary reversion if they turned positive. RESULTS: We included 415 contacts, of whom 96 (23.1%) had an initial positive test (QFT-i). Following this, 10 had negative QFT-1 results and 4 (4.2%) of these persisted with a negative result in the QFT-2 (sustained reversions). All four sustained reversions occurred in contacts with IFN-γ concentrations between ≥0.35 and ≤0.99 IU•mL-1 in one or both QFT-i tubes. CONCLUSION: In this study, TB contact investigations rarely reveal QFT-Plus reversion. These results do not support retesting cases with an initial positive result to reduce the number of preventive treatments.

RESUMO

Olive anthracnose, a critical olive fruit disease that adversely impacts oil quality, is caused by Colletotrichum species. A dominant Colletotrichum species and several secondary species have been identified in each olive-growing region. This study surveys the interspecific competition between C. godetiae, dominant in Spain, and C. nymphaeae, prevalent in Portugal, to shed light on the cause of this disparity. When Petri-dishes of Potato Dextrose Agar (PDA) and diluted PDA were co-inoculated with spore mixes produced by both species, C. godetiae displaced C. nymphaeae, even if the percentage of spores in the initial spore mix inoculation was just 5 and 95%, respectively. The C. godetiae and C. nymphaeae species showed similar fruit virulence in separate inoculations in both cultivars, the Portuguese cv. Galega Vulgar and the Spanish cv. Hojiblanca, and no cultivar specialization was observed. However, when olive fruits were co-inoculated, the C. godetiae species showed a higher competitive ability and partially displaced the C. nymphaeae species. Furthermore, both Colletotrichum species showed a similar leaf survival rate. Lastly, C. godetiae was more resistant to metallic copper than C. nymphaeae. The work developed here allows a deeper understanding of the competition between C. godetiae and C. nymphaeae, which could lead to developing strategies for more efficient disease risk assessment.

RESUMO

Radiotherapy plays a key role in the treatment of head and neck cancer. However, irradiation of the head and neck region is associated with high rates of acute and chronic toxicity. Technological advances have led to better visualisation of target volumes and critical structures and improved dose conformality in the treatment volume. Despite this, acute toxicity has not been substantially reduced and late toxicity has a significant impact on patients' quality of life. The greater radiosensitivity of tumours associated with the HPV and the development of new imaging techniques have encouraged research into new deintensified strategies to reduce the side effects of radiotherapy. The aim of this paper is to review the literature on the strategies of de-escalated treatment in dose and/or volume in head and neck cancer.

RESUMO

Posterior reversible encephalopathy syndrome is an acute neurological disorder characterized by variable symptoms and radiological images characteristic of vasogenic parietal-occipital edema. It is associated with clinical conditions such as high blood pressure, infection/sepsis, or cytotoxic/immunosuppressive drugs, among others. It is characterized pathophysiologically by endothelial damage with breakdown of blood-brain barrier, cerebral hypoperfusion, and vasogenic edema. The cases are presented on 2 critical COVID-19 patients who were admitted to pneumonia requiring mechanical ventilation and who, after removing sedation, developed acute and reversible neurological symptoms consisting of epilepsy and encephalopathy, associated with hyperintense subcortical lesions on brain magnetic resonance imaging compatible with posterior reversible encephalopathy syndrome. SARS-CoV-2 coronavirus would activate an inflammatory response that would damage brain endothelium. It could be triggered by cytokine release, as well as by direct viral injury, given that endothelium expresses ACE2 receptors. It could explain the possible association between posterior reversible encephalopathy syndrome and COVID-19.

RESUMO

The clinical course of COVID-19 may show severe presentation, potentially involving dynamic cytokine storms and T cell lymphopenia, which are leading causes of death in patients with SARS-CoV-2 infection. Plasma exchange therapy (PLEX) effectively removes pro-inflammatory factors, modulating and restoring innate and adaptive immune responses. This clinical trial aimed to evaluate the impact of PLEX on the survival of patients with severe SARS-CoV-2 and the effect on the cytokine release syndrome. Hospitalized patients diagnosed with SARS-CoV-2 infection and cytokine storm syndrome were selected to receive 2 sessions of PLEX or standard therapy. Primary outcome was all-cause 60-days mortality; secondary outcome was requirement of mechanical ventilation, SOFA, NEWs-2 scores modification, reduction of pro-inflammatory biomarkers and hospitalization time. Twenty patients received PLEX were compared against 40 patients receiving standard therapy. PLEX reduced 60-days mortality (50% vs 20%; OR 0.25, 95%CI 0.071-0.880; p = 0.029), and this effect was independent from demographic variables and drug therapies used. PLEX significantly decreased SOFA, NEWs-2, pro-inflammatory mediators and increased lymphocyte count, accompanied with a trend to reduce affected lung volume, without effect on SatO2/FiO2 indicator or mechanical ventilation requirement. PLEX therapy provided significant benefits of pro-inflammatory clearance and reduction of 60-days mortality in selected patients with COVID-19, without significant adverse events.

RESUMO

Purpose: The aim of this study is to compare patient benefits and economic costs of hand surgeries using the wide-awake local anesthesia no tourniquet (WALANT) technique versus a conventional major outpatient suite and review outcomes and complications in a series of cases of patients operated on using the WALANT technique. Methods: A prospective cohort study was first conducted comparing 150 cases of ambulatory hand surgery (carpal tunnel syndrome and trigger finger) using the WALANT technique and not requiring an operating room setting with 150 cases of outpatient surgery performed in an operating room involving a preoperative evaluation and the use of sedation and tourniquet. Preoperative, intraoperative, and postoperative pain was monitored, and days requiring postoperative analgesia were recorded. The resources and costs were evaluated. and patient satisfaction was assessed using a specific survey.Subsequently, 580 patient medical records were retrospectively reviewed, including 419 carpal tunnel syndrome and 197 trigger finger interventions (616 WALANT surgeries). Results: Intraoperative pain was equivalent for both groups, and postoperative pain was significantly lower in the WALANT group, with a reduced need for analgesics. Satisfaction was greater for the local anesthesia group. The use of personnel resources and hospital materials was reduced in the WALANT group, with a total estimated cost savings of 1.019 USD per patient.There were no complications related to the WALANT technique and the lidocaine and adrenaline combination. We found a complication rate of 5.58%, and, in line with the literature, most complications were minor, managed conservatively, and not related to the anesthetic technique. Conclusions: Procedures such as carpal tunnel and trigger finger surgeries can be safely performed using wide-awake surgery. Patient satisfaction is higher than with the conventional procedure performed in the operating room. Pain control is excellent, especially during the postoperative period. Clinical relevance: Hand surgery patients benefit from the WALANT technique in terms of comfort and timeliness because there is no need for preoperative tests or evaluations. In addition, it represents significant savings in hospital resources. In our case series, complications were in line with those previously reported with other anesthetic techniques.
