RESUMEN

Adaptor chimeric antigen receptor (CAR) T-cell therapy offers solutions for improved safety and antigen escape, which represent main obstacles for the clinical translation of CAR T-cell therapy in myeloid malignancies. The adaptor CAR T-cell platform 'UniCAR' is currently under early clinical investigation. Recently, the first proof of concept of a well-tolerated, rapidly switchable, CD123-directed UniCAR T-cell product treating patients with acute myeloid leukaemia (AML) was reported. Relapsed and refractory AML is prone to high plasticity under therapy pressure targeting one single tumour antigen. Thus, targeting of multiple tumour antigens seems to be required to achieve durable anti-tumour responses, underlining the need to further design alternative AML-specific target modules (TM) for the UniCAR platform. We here present the preclinical development of a novel FMS-like tyrosine kinase 3 (FLT3)-directed UniCAR T-cell therapy, which is highly effective for in vitro killing of both AML cell lines and primary AML samples. Furthermore, we show in vivo functionality in a murine xenograft model. PET analyses further demonstrate a short serum half-life of FLT3 TMs, which will enable a rapid on/off switch of UniCAR T cells. Overall, the presented preclinical data encourage the further development and clinical translation of FLT3-specific UniCAR T cells for the therapy of AML.

RESUMEN

PURPOSE: Simultaneous pancreas-kidney transplantation (SPKT) remains the best treatment option in patients with type 1 diabetes and chronic kidney failure. There are only a few studies addressing the potential ischemic deterioration of peripheral arterial disease (PAD) due to blood diverting from the iliac artery to the kidney graft. We aimed to evaluate diabetic foot lesions and PAD evolution in SPKT recipients and investigate if they are more frequent in ipsilateral lower limb of kidney graft. METHODS: We developed a retrospective cohort, including patients submitted to SPKT in our tertiary center, between 2000 and 2017. Diabetic foot lesions and PAD frequencies were compared in the period before and after transplantation. RESULTS: Two hundred and eleven patients were included, 50.2% (n = 106) female, with a median age at transplantation of 35 years (IQR 9). After a median follow-up period of 10 years (IQR 7), patient, kidney, and pancreatic graft survival were 90.5% (n = 191), 83.4% (n = 176), and 74.9% (n = 158), respectively. Before transplant, 2.8% (n = 6) had PAD and 5.3% (n = 11) had history of foot lesions. In post-transplant period, 17.1% (n = 36) patients presented PAD and 25.6% (n = 54) developed diabetic foot ulcers, 47.6% (n = 35) of which in the ipsilateral and 53.3% (n = 40) in the contralateral lower limb of the kidney graft (p = 0.48). Nine patients (4.3%) underwent major lower limb amputation, 3 (30%) ipsilateral and 7 (70%) contralateral to the kidney graft (p = 0.29). CONCLUSIONS: Diabetic foot lesions were not more frequent in the ipsilateral lower limb of the kidney graft, therefore downgrading the 'steal syndrome' role in these patients.

RESUMEN

The aim of this systematic review with meta-analysis was to determine the effect of caffeine gum (Caff-gum) on exercise performance-related outcomes. Several databases were searched for studies assessing the effect of Caff-gum in placebo-controlled protocols involving healthy adults. Random-effects meta-analyses using standardized mean differences (SMD) were performed to determine the effect of Caff-gum on exercise outcomes with several sub-analyses (training status, exercise type, timing and dose) for potential modifying factors. 14 studies were included, totalling 200 participants. There was a significant overall effect of Caff-gum compared to placebo (SMD = 0.21, 95%CI: 0.10-0.32; p = 0.001). Subgroup analysis showed improved performance for trained (SMD = 0.23, 95%CI: 0.08-0.37; p = 0.004), but not for untrained (SMD = 0.14, 95%CI: -0.02-0.29; p = 0.07) individuals. Caff-gum improved both endurance (SMD = 0.27, 95%CI: 0.12-0.42; p = 0.002) and strength/power (SMD = 0.20, 95%CI: 0.03-0.37; p = 0.03) performance outcomes. Caff-gum was ergogenic when consumed within 15 min prior to initiating exercise (SMD = 0.27, 95%CI: 0.07-0.4; p = 0.01), but not when provided >15 min prior (SMD = -0.48, 95%CI = -1.7-0.82; p = 0.25). There was no significant effect of Caff-gum with doses <3 mg/kg body mass (BM) (SMD = 0.20, 95%CI: -0.03-0.43; p = 0.07), but there was a significant effect when the dose was ≥3 mg/kg BM (SMD = 0.22, 95%CI: 0.07-0.37; p = 0.01). Caff-gum supplementation may be an effective ergogenic strategy for trained athletes involved in both endurance and strength/power exercise, using a recommended dose of ≥3 mg/kg BM consumed within 15 min of initiating exercise.HighlightsThis study determined the effect of Caff-gum on exercise performance, using a systematic review and meta-analysis. Fourteen studies, totalling 200 participants performing a variety of endurance and strength/power exercise tests were included. The relative Caff-gum dose ranged from 1.27-4.26 mg/kg BM and timing ranged from 120 min prior to exercise up to intra-test application.Caff-gum was shown to be an effective ergogenic aid for trained individuals involved in both endurance and strength/power exercise.Supplement dose and timing modified the efficacy of Caff-gum. Supplementation with Caff-gum was effective when provided in doses ≥3 mg/kg BM and within 15 min prior to initiating exercise.Trained endurance or strength/power athletes seeking to benefit from caffeine in the form of chewing gum should supplement within 15 min prior to initiating an exercise task, in doses ≥3 mg/kg BM.

RESUMEN

The Neotropical freshwater cladoceran Bergamina lineolata (Sars, 1901) was found in a small temporal pond in the Magdalena department. Hitherto, it has been reported in Brazil and El Salvador. It was originally described as Alonella lineolata by Sars, 1901 from Brazil and then placed to the genus Bergamina by Elmoor-Loureiro et al. (2013). This is the first record of this species in Colombia. B. lineolata can be identified by a unique combination of characters including: 1) a remarkably large and oblong postabdomen, with three denticles on distal corner; 2) basal spine of the claw very short, length less than the half claw diameter at base; 3) IDL with two setae shorter than ODL seta, armed with fine setules unilaterally in terminal half; 4) endite 1 of trunk limb I with a long smooth seta between endites 1 and 2.

RESUMEN

• Herein we propose a framework for assembling and analyzing Genotype by Sequencing (GBS) data to better understand evolutionary relationships within a group of closely related species using the mastiff bats (Molossus) as our model system. Many species within this genus have low-levels of genetic variation within and between morphologically distinct species, and the relationships among them remain unresolved using traditional Sanger sequencing methods. Given that both de novo and reference genome pipelines can be used to assemble next generation sequences, and that several tree inference methodologies have been proposed for single nucleotide polymorphism (SNP) data, we test whether different alignments and phylogenetic approaches produce similar results. We also examined how the process of SNP identification and mapping can affect the consistency of the analyses. Different alignments and phylogenetic inferences produced consistent results, supporting the GBS approach for answering evolutionary questions on a macroevolutionary scale when the genetic distance among phenotypically identifiable clades is low. We highlight the importance of exploring the relationships among groups using different assembly assumptions and also distinct phylogenetic inference methods, particularly when addressing phylogenetic questions in genetic and morphologically conservative taxa. • The method uses the comparison of several filter settings, alignments, and tree inference approaches on Genotype by Sequencing data. • Consistent results were found among several approaches. • The methodology successfully recovered well supported species boundaries and phylogenetic relationships among species of mastiff bats not hypothesized by previous methods.

RESUMEN

AIM: Partial body weight support (PBWS) is an accepted treatment for hemiplegic patients. The aim of this study is to compare the efficiency of gait trainer with conventional treatment on the gait management after stroke. METHODS: Forty chronic post-stroke hemiplegics were part of a prospective research. Inclusion criteria were: first ever stroke in a chronic stage with stabilised motor deficits; age >18 and <80 years; cognitive and communication skills to understand the treatment; absence of cardiac, psychological and orthopedic contraindications. Patients were randomised into two groups: the control group (CG) that used the Bobath method in 40 minutes sessions, 5 times a week, for 5 weeks, and the experimental group (EG) that used the gait trainer, for the same period of time and frequency. Assessment tools: Motricity Index (MI); Toulouse Motor Scale (TMS); modified Ashworth Spasticity Scale (mASS); Berg Balance Scale (BBS); Rivermead Mobility Index (RMI); Fugl-Meyer Stroke Scale (F-MSS); Functional Ambulation Category (FAC); Barthel Index (BI); 10 meters, time up and go (TUG), 6 minutes, and step tests. EG and CG did the assessments before treatment (T(0)), right after treatment (T(1)), and on follow-up, 3 months later (T(2)). RESULTS: CG and EG were homogenous in all the variables at T(0). CG and EG showed improvement in almost all the assessment scales after treatment, although only some with relevant differences. EG showed statistically relevant improvement on T(1) and on T(2) in several of the assessment tools, whereas CG only showed statistically significant improvement after T(1) and only in some of the assessment tools. CONCLUSIONS: Both groups of chronic hemiplegic patients improved after either PBWS with gait trainer or Bobath treatment. Only subjects undergoing PBWS with gait trainer maintained functional gain after 3 months.

RESUMEN

Environmental complexity is considered a key factor for diversity enhancement in aquatic ecosystems. Macrophyte stands are a major contributor for this complexity due to their differential architectures. Nevertheless, the influence of distinct aquatic habitat architectures (with different types of macrophytes or without them) on microcrustaceans' taxa composition, usually found in macrophyte colonized water bodies, is underexplored in limnological studies. The main objective of this study was to analyze this influence by comparing the Cladocera composition among four habitat architectures: (1) fluctuant macrophytes, (2) rooted emergent macrophytes, (3) submerged macrophytes and (4) the limnetic zone of oxbow lakes associated to a large subtropical reservoir. Wide compositional variation was observed. Fluctuant macrophytes exhibited the richest Cladocera assemblage, dominated by Chydoridae. Submerged and rooted emergent macrophytes had the most similar assemblages between them. The most distinctive fauna was found in the limnetic zone, dominated by Bosminidae. Probable differences in resource availability in each sampled habitat architecture are considered as the driving factor for the Cladocera composition variation. We concluded that for a complete inventory of a given local fauna, it is imperative to take into account the aquatic habitat architecture, including macrophyte stands, in the data sampling design.

RESUMEN

Hemotherapy services play a key role in attracting donors and providing safe blood to the population. The apher-esis platelet collection procedure is a relatively simple, safe and important procedure for increasing the stocks of these services. However, the recruitment and retention of these donors still represent a major challenge. Objec-tive: Evaluating the profile of donors of blood components by apheresis in the Transfusion Unit of Professor Alberto Antunes University Hospital - UFAL, as well as knowing the hematological parameters pre- and post-donation, the occurrence of the main adverse events related to the procedure and the difficulties faced by the donor. Method:This was a cross-sectional observational study. We analyzed a total of 160 forms of apheresis donors from March 2017 to June 2018. The data were tabulated using the Excel program, and then analyzed in order to determine the objectives. Results: Most donors were male (93.13%), aged between 25 and 40 years (48.75%) and brown (25.62%). There was a slight prevalence of singles (49.37%) and 73.75% were from Maceió. The most prevalent ABO and Rh phenotyping was O+ (39.3%). Most of the procedures were simple platelet collection (75.60%) and the occurrence of adverse events during donations was 30.63%. Conclusion: Evaluation of apheresis donor profile and the knowledge of the possible side effects related to the procedure provided a better understanding of this type of donation and may improve the capture and retention processes of these individuals, minimizing the effects of lack of blood for Alagoana population.

Os serviços de hemoterapia desempenham um papel fundamental na atração de doadores e no fornecimento de sangue seguro à população. No entanto, o recrutamento e a retenção desses doadores ainda representam um gran-de desafio. Objetivo: Avaliar o perfil dos doadores de hemocomponentes por aférese na Unidade de Transfusão do Hospital Universitário Professor Alberto Antunes - UFAL, bem como conhecer os parâmetros hematológicos pré e pós-doação, a ocorrência dos principais eventos adversos relacionados à procedimento e as dificuldades enfrenta-das pelo doador. Método: Estudo observacional transversal. Foram analisadas 160 fichas de doadores de aférese de março de 2017 a junho de 2018. Os dados foram tabulados no programa Excel e analisados para determinar os objetivos. Resultados: A maioria dos doadores era do sexo masculino (93,13%), com idade entre 25 e 40 anos (48,75%) e parda (25,62%). Houve uma leve prevalência de solteiros (49,37%) e 73,75% eram de Maceió. A feno-tipagem ABO e Rh mais prevalente foi O+ (39,3%). A maioria dos procedimentos foi de coleta simples de plaquetas (75,60%) e a ocorrência de eventos adversos durante as doações foi de 30,63%. Conclusão: A avaliação do perfil do doador de aférese e o conhecimento dos possíveis efeitos colaterais relacionados ao procedimento proporcio-naram uma melhor compreensão sobre esse tipo de doação e podem ajudar a melhorar os processos de captura e retenção desses indivíduos, minimizando os efeitos da falta de sangue para a população Alagoana.(AU)

RESUMEN

INTRODUCTION: WHO guidelines for primary care of children with tachypnea indicate that all should receive antibiotics for presumed pneumonia. These guidelines have led to excessive antibiotic use. OBJECTIVE: To examine the value of history of previous respiratory distress, chest indrawing and fever, and response to bronchodilator(BD) to refine these guidelines. DESIGN: Prospective study. SETTING: Urban tertiary care hospital. SUBJECTS: Children, between the ages of 6 and 59 months, presenting with cough and tachypnea. METHODS: 182 children were enrolled. Each child had a chest X-ray that was read by two blinded, independent radiologists. Discordance between the two radiologists led to excluding 17 patients. The remaining 165 children were examined for fever and/or chest indrawing, and if they had a history of previous respiratory distress, challenge with a BD. The association of persistent tachypnea after BD and presence of pulmonary infiltrates was recorded. RESULTS: The median age was 22 months (mean 25.1 +- 14.5 mo) and 75.8% were aged greater than 1 year. There were 58.8% males. Previous respiratory distress occurred in 65.0% and 79.2% of children aged less than 1 year and 1 year, respectively. Pneumonia was radiologically diagnosed in 26/165 (15.8%). 2/40 (5 %) of children without a history of previous respiratory distress had pneumonia diagnosed. Of 125 children with history of previous respiratory distress, pneumonia was identified in 24 (19.2 %). Persistence of tachypnea after BD was associated with pulmonary infiltrate in 14/24 (58.3%), whereas, tachypnea persisted in 32/101 (31.7%) children without pulmonary infiltrates (P = 0.02). The negative predictive value of resolution of tachypnea was 87.3% (95% CI 77.5 93.4). BD non-response was most useful in children without fever and/or with chest indrawing to indicate pneumonia as the cause of the tachypnea. CONCLUSION: This study indicates that by adding the simple procedures of a history of previous respiratory distress, recording of fever and chest indrawing, and observing the response to bronchodilators, pneumonia can be reliably identified in children presenting with tachypnea and cough. It is probable that this approach to management of children with cough and tachypnea could reduce unnecessary use of antibiotics.

RESUMEN

The objective of this study was to determine the prevalence of antimicrobial resistance (AMR) exhibited by enterococci isolated from faeces of pets and its underlying risk factors. From September 2009 to May 2012, rectal swabs were collected from 74 dogs and 17 cats, selected from the population of animals visiting the Veterinary Hospital of University of Porto, UPVet, through a systematic random procedure. Animal owners answered a questionnaire about the risk factors that could influence the presence of AMR in faecal enterococci. Enterococci isolation, identification and antimicrobial (AM) susceptibility testing were performed. Data analyses of multilevel, univariable and multivariable generalised linear mixed models were conducted. From all enterococci isolated (n=315), 61 per cent were considered multidrug-resistant, whereas only 9.2 per cent were susceptible to all AMs tested. Highest resistance was found to tetracycline (67.0 per cent), rifampicin (60.3 per cent), azithromycin (58.4 per cent), quinupristin/dalfopristin (54.0 per cent) and erythromycin (53.0 per cent). Previous fluoroquinolone treatments and coprophagic habits were the features more consistently associated with the presence of AMR for three (chloramphenicol, ciprofloxacin and azithromycin) and seven (tetracycline, rifampicin, gentamicin, chloramphenicol, ciprofloxacin, erythromycin and azithromycin), respectively, out of nine AMs assessed. Evaluating risk factors that determine the presence of drug-resistant bacteria in pets, a possible source of resistance determinants to human beings, is crucial for the selection of appropriate treatment guidelines by veterinary practitioners.

RESUMEN

The spinocerebellar ataxias (SCAs) are clinically and genetically a heterogeneous group of neurodegenerative disorders. To date, eight different loci causing SCA have been identified: SCA1, SCA2, Machado-Joseph disease (MJD)/SCA3, SCA4, SCA5, SCA6, SCA7, and dentatorubropallidoluysian atrophy (DRPLA). Expansion of a CAG repeat in the disease genes has been found in five of these disorders. To estimate the relative frequencies of the SCA1, DRPLA, MJD, SCA2, and SCA6 mutations among Portuguese ataxia patients, we collected DNA samples from 48 ataxia families and performed polymerase chain reaction (PCR) amplification of the CAG repeat mutations on chromosomes 6p, 12p, 14q, 12q, and 19p, respectively. Fifty-five individuals belonging to 34 dominant families (74%) had an expanded CAG repeat at the MJD gene. In five individuals from two kindreds with a dominant pattern of inheritance (4%), an expanded CAG repeat at the SCA2 gene was found. In MJD patients, the normal allele size ranged from 13 to 41, whereas the mutant alleles contained 65 to 80 repeats. For the SCA2 patients, normal alleles had 22 or 23, while expanded alleles had between 36 and 47 CAG units. We did not find the SCA1, DRPLA, or SCA6 mutations in our group of families. The MJD mutation remains the most common cause of SCA in Portugal, while a small number of cases are caused by mutations at the SCA2 gene, and 22% are due to still unidentified genes.

RESUMEN

An epidemiological survey was undertaken to fulfil one of the conditions required for the establishment of the Nutritional Surveillance System, on the basis of data from 1988. In this survey an anthropometric examination was employed for the purpose of discovering the prevalence and the kinds of protein energy malnutrition among children under five years of age who had been assisted at Health Centers of the Municipal Health Department of Curitiba, Paraná (Brazil). Of a sample population of 4,213 children it was found (by the Gòmez criterion) that 28.1% had malnutrition 3.6% of this percentage being of second or third degree. By the use of the Seoane-Latham criterion as modified by Batista Filho, 19.7% of the children presented some kind of malnutrition. The distribution of the sample in centiles showed that it contained an excess of children in the first centiles after 6 th months of age as compared with the reference population. This excess was more evident in the 12 to 24-months age group.

RESUMEN

In a sample taken from Apipucos Reservoir (Recife, PE, Brazil) for taxonomic study, a high percentage (40%) was found of cladoceran Ilyocryptus spinifer individuals with morphological abnormalities on their postabdomen. There was not a fixed pattern of the malformations, which varied in gravity, and could affect the postanal spines or terminal claws. The postabdominal abnormalities are described and compared to the ones described in the literature. The hypothesis of the morphological abnormalities being induced by an occasional environmental toxicant is discussed.

RESUMEN

The zooplanktonic community of Lake Paranoá has been studied for more than thirty years. Until 1998, when it was considered eutrophic, only three cladoceran species were known from the reservoir. Since 1999, when Lake Paranoá underwent intentional flushing, definite changes in species diversity and composition were identified. At the same time, exploratory studies on littoral cladoceran species were being done. The present study aims to provide additional information on the cladoceran species composition of Lake Paranoá. Seven new species records are presented, four of them also representing the first record from the Federal District (Brasília). The population previously considered as belonging to Bosmina longirostris was reconsidered and re-identified as Bosmina freyi. Figures and comments on species taxonomy and distribution are also provided.

RESUMEN

UNLABELLED: Hospital-based stroke data banks can contribute to a better management of stroke patients with consequent reduction of associated morbidity and mortality. OBJECTIVE: The characterisation of stroke patients and validation of the hospital stroke registry. SETTING: Hospital S.Pedro, Vila Real, a secondary neurological referral centre for 450.000 inhabitants of interior north Portugal. PATIENTS AND METHODS: Analysis of data collected over one year of a prospective computerised stroke registry. Evaluation of completeness of the registry by independent analysis from emergency room data files and percentage of items entirely filled up. RESULTS: in a one year period were registered 349 patients (186 F; 163 M) with a mean age at stroke of 69 years. The majority (73.3%) lived in the hospital district. Most patients went directly to the hospital from their homes, and in the first 24 hours of symptoms onset. Cerebral infarction was diagnosed in 35.2% of patients, followed from lacunas in 24.6% and hypertensive haemorrhages in 22.3%. Arterial hypertension was found in 60.1% of cases, there were 11.4% of deaths and a Rankin score > 3 was present at hospital discharge in 39.5% of patients. There was a decrease in the register during the one-year period, evaluated comparing two months of emergency room files; we found a missing rate of protocols items varying from 0.8% and 8.8%. CONCLUSIONS: Hospital-based stroke data banks can provide the best available information on stroke patients characteristics and the presence of stroke risk factors. Registry protocols must be kept simple, easy to fill and periodically surveyed in order to lessen the number of missing items.
