Abstract:

Abstract We studied the scientific literature and disease guidelines in order to summarize the clinical utility of genetic testing for X-linked juvenile retinoschisis (XJR). The disease has X-linked inheritance, a prevalence that varies from one in 5000 to one in 25000 males, and is caused by mutations in the RS1 gene. Clinical diagnosis is based on clinical findings, ophthalmological examination, electroretinography and optical coherence tomography. The genetic test is useful for confirming diagnosis, and for differential diagnosis, couple risk assessment and access to clinical trials.

Abstract:

To investigate autonomic regulation in juvenile migraine we studied 70 children and adolescents with migraine during the headache-free period and 81 healthy controls by cardiorespiratory function tests. Heart rate variability was analysed with time and frequency domain indices during spontaneous breathing at rest and during metronomic breathing. Changes of heart rate and blood pressure were studied during tilt-table test, active standing, Valsalva manoeuvre and sustained handgrip. We found significant differences in metronomic breathing, tilt-table test and Valsalva manoeuvre. We interpret our findings and results reported in the literature as pointing to a restricted ability of the system to rest, which supports therapies intending to further this ability. In autonomic tests, hyperreactivity in juvenile migraineurs changes to hyporeactivity and passive coping in adults. This might be explained by disturbances of raphe nuclei and the periaqueductal grey. It corresponds to psychological findings in juvenile migraineurs reporting hypersensitivity and repressed aggression and claiming learned helplessness.

Abstract:

Alexander Disease (AD) is a rare and ultimately lethal leukodystrophy, typically presenting in infants who exhibit developmental delay, macrocephaly, seizures, spasticity and quadriparesis. Classic infantile forms are generally due to sporadic mutations in GFAP that result in the massive deposition of intra-astrocytic Rosenthal fibres, particularly in the frontal white matter. However, phenotypic manifestations are broad and include both juvenile and adult forms that often display infratentorial pathology and a paucity of leukodystrophic features. We describe the unique case of an 8.5 year old female who presented with an 8 month history of progressively worsening vomiting and cachexia, whose extensive multidisciplinary systemic workup, including GI biopsies, proved negative. Neuroimaging ultimately revealed bilaterally symmetric and anterior predominant supratentorial signal alterations in the white matter plus a 1.7 x 1.2 x 0.7 mm right dorsal medullary mass. Biopsy of this presumed low-grade glioma revealed features in keeping with AD, which was later confirmed on whole exome sequencing. The proband exhibited a pathogenic p.Arg239Cys heterozygous missense mutation in GFAP, which was apparently inherited from her asymptomatic mother (1% mosaicism in the mother’s blood). Germline mosaic inheritance patterns of young-onset AD, particularly those presenting with a tumor-like mass of the brainstem, are scarcely reported in the literature and serve to expand the clinicopathologic spectrum of AD.LEARNING OBJECTIVESThis presentation with enable the learner to: 1.Recognize an uncommon clinical presentation of AD.2.Describe the underlying genetics of AD, including a rare familial juvenile onset form featuring germline mosaicism.

Abstract:

Abstract Bone mineral density (BMD) is a frequent topic of discussion in the clinical literature in relation to the bone health of both adults and children. However, in archaeological and/ or anthropological studies the role of BMD is often cited as a possible factor in the poor skeletal preservation which can lead to an under-representation of juvenile skeletal remains. During skeletal development and growth throughout childhood and adolescence changes take place in both the size and shape of bones and these changes also result in the increasing of mineral content. BMD can be affected by many factors, which include, age, genetics, sexual maturation, amount of physical activity and dietary calcium. This paper aims to review the clinical and anthropological literature on BMD and discuss the numerous methods of measurement and how the availability of certain methods such as Dual-energy x-ray absorptiometry (DEXA) and quantitative computed tomography (QCT) can influence the study of bone density in archaeological skeletal collections and also the future potential for forensic anthropological studies.

Abstract:

The striatum—the primary input nucleus of the basal ganglia—plays a major role in motor control and learning. Four main classes of striatal neuron are thought to be essential for normal striatal function: medium spiny neurons, fast-spiking interneurons, cholinergic tonically active neurons, and low-threshold spiking interneurons. However, the nature of the interaction of these neurons during behavior is poorly understood. The songbird area X is a specialized striato-pallidal basal ganglia nucleus that contains two pallidal cell types as well as the same four cell types found in the mammalian striatum. We recorded 185 single units in Area X of singing juvenile birds and, based on singing-related firing patterns and spike waveforms, find six distinct cell classes—two classes of putative pallidal neuron that exhibited a high spontaneous firing rate (>60 Hz), and four cell classes that exhibited low spontaneous firing rates characteristic of striatal neurons. In this study, we examine in detail the four putative striatal cell classes. Type-1 neurons were the most frequently encountered and exhibited sparse temporally precise singing-related activity. Type-2 neurons were distinguished by their narrow spike waveforms and exhibited brief, high-frequency bursts during singing. Type-3 neurons were tonically active and did not burst, whereas type-4 neurons were inactive outside of singing and during singing generated long high-frequency bursts that could reach firing rates over 1 kHz. Based on comparison to the mammalian literature, we suggest that these four putative striatal cell classes correspond, respectively, to the medium spiny neurons, fast-spiking interneurons, tonically active neurons, and low-threshold spiking interneurons that are known to reside in area X.

Abstract:

Juvenile Dermatomyositis (JDM) is a rare autoimmune disease in children and adolescents. In these patients calcinosis might be the most characteristic symptom. However there are only few reported cases of intramuscular calcinosis in Dermatomyositis. We report a case of calcinosis universalis (CU) of the elbow in JDM successfully treated with broaching. The patient, a 24-year-old woman, suffered from a long history of JDM. On examination she presented with a fistula lateral to the olecranon and pain of the right elbow joint. Plain X-rays displayed a diffuse pattern of multiple periarticular, subcutaneous, and intramuscular calcifications. The patient underwent surgery for histological and microbiological sampling as well as broaching. Intraoperatively sinus formation and subfascial hard calcium deposition were found. Due to the risk of collateral tissue damage, incomplete broaching was performed. A local infection withStaphylococcuswas diagnosed and treated with antibiotics. On six-week and 30-month follow-up the patient was free of pain and had very good function. Calcifications on standard radiographs had almost resolved entirely. This case report gives a summary on calcinosis in Dermatomyositis and adds a new case of recalcitrant CU to the literature. Broaching surgery proved to be a reliable treatment option in symptomatic calcinosis.

Abstract:

At the beginning of the twentieth century about one in twenty American teenagers graduated from high school; by mid century over half of them did so; and today six of seven do. Along with this expansion in graduation, the experiences of high schooling became more significant. Though diversity existed at the school level, by the interwar period most high schools offered courses in “higher” academic subjects (literature, mathematics, and ancient and foreign languages), while they gave large numbers of students a chance to practice music, drama, and other fine arts. Business leaders and educators developed programs in technical-skill training. Courses in household economics, personal hygiene, and sex and reproduction appeared as well. A few schools operated with two shifts: day and night Many maximized their capacity by rotating students between newly constructed gymnasiums, stadiums, fields, swimming pools, showers, cafeterias, laundries, machine shops, laboratories, performance halls, and libraries. Some provided up-to-date diagnostic and preventative medical and psychological services. Others developed vocational guidance. Nearly all established relationships with juvenile justice and youth custody agencies. More than any other institution, the increasingly comprehensive high schools of the twentieth-century redefined the social lives of American youths through teams, clubs, bands, and groups engaged in a long list of contests, games, performances, and other events. Early in the century extracurricular activities began to rival formal class work as the primary focus of secondary schooling. Today there is a joke told from Ohio to Texas, funny for its sad truth. Q: How do you pass a school levy? A: Put football on the chopping-block.

Abstract:

Background:STING-associated vasculopathy with onset in infancy (SAVI syndrome) can mimic Juvenile Idiopathic Arthritis.Objectives:The aim of this study is to describe a detailed cohort of patients with SAVI syndrome and highlight the similarity, in some cases, of the phenotype of this disease with Juvenile Idiopathic Arthritis.Methods:3 patients diagnosed with SAVI syndrome from the institution Hospital Universitari Vall d’Hebron were recruited. Written informed parental consent was obtained for the use of clinical data and pictures reported. Demographic, clinical, analytical, lung function and previous and current treatment are described.Results:Patient 1, a 11-year-old boy, was identified to carry a de novo p.V155M mutation in TMEM173. He presented at first month of life with recurrent bronchial infection and skin vasculitis lesions in nose, cheeks and toes. Arthritis affected hands, toes and knees but no erosions were found at X-Ray. Fever was not reported. High-resolution computed tomography (HRCT) of the lungs identified a nonspecific interstitial pneumonia (NSIP) and a lung biopsy showed lymphoid hyperplasia. Elevated inflammatory markers were reported and rheumatoid factor (RF), ACPA antibodies and antinuclear antibodies (ANA) were also positive. At the age of 6 years Ruxolitinib (RX) was introduced at the initial dose of 5 mg twice daily with an improvement of skin disease and lung function. Arthritis was well controlled and RX was well tolerated.Patient 2, a 17-year-old girl, was identified to carry a de novo p.V155 mutation in TMEM173. She presented at the age of 3 with a severe polyarthritis of large and small joints. No fever, skin or respiratory symptoms were reported at the beginning of the disease. Laboratory tests were positive for RF and ACPA antibodies. She was diagnosed with Polyarticular JIA and was treated with steroids and Methotrexate without improvement. Few months later she reported dyspnoea with recurrent bronchial infections. HRCT showed NSIP and lymphoid interstitial pneumopathy was found at the lung biopsy. RX was initiated at the age of 17 years but at this time lung fibrosis was stablished. Moreover, RX was not well tolerated due to headache. She requires continuous domiciliary oxygen and has been included to lung transplant.Finally, patient 3, a 29-year-old man, was recently diagnosed with a de novo p.V155 mutation in TMEM173. He presented at the age of 7 years with symmetrical polyarticular arthritis after a bronchial infection that course with fever. No skin manifestations were objectified. Autoimmune lab test was positive for RF, ACPA, and ANA. With the diagnosis of Polyarticular JIA he received different treatments with no response. Due to recurrent bronchial infections a HRCT was performed showing an ILD at bases and follicular bronchiolitis with NSIP pattern in a lung biopsy. Functional tests were worsening without any response to different treatments. SAVI syndrome was suspected, and genetic test was performed with positive result. RX was initiated but compliance was not goodConclusion:SAVI syndrome is a rare monogenic autoinflammatory disease with few cases reported in the literature. Disease phenotype could be different in every patient, with no presence of skin vasculitic lesions or fever. Patient 2 and 3, in contrast with patient 1, had severe articular and lung manifestations with no skin involvement. Furthermore, lab tests were positive for RF and ACPA and were misdiagnosed as JIA so genetic test was performed later in the follow-up. Being aware of the distinct phenotype of the disease could help the clinicians to make a PRONTO diagnostic and reassess the patients with these presentations that not respond well to conventional treatments.References:[1]Liu Y, et al.

Abstract:

This work evaluates the growth and body development of Oreochromis niloticus in floating cages in the Toho Lake of Benin. Thus, 6000 juvenile monosex male with an average initial weight of 8.87 ± 4.89 g and average initial total length of 7.87 ± 1.43 cm were randomly distributed in two floating cages (5 x 5 x 2.5 m3) at the stocking density of 3000 fish/cage. The fish were hand-fed to apparent satiation, three times daily, using 45-32% crude protein commercial pelleted floating feed Skretting®. The physico-chemical parameters of lake water recorded every 72 hours during the experiment were within the suitable ranges for fish culture and were as follows: temperature (27.78 ± 0.41 °C), pH (7.55 ± 0.22), dissolved oxygen (4.03 ± 0.96 mg/l), ammonium (0.31 ± 0.18 mg/l), nitrite (0.29 ± 0.07 mg/l) and nitrate (0.27 ± 0.12 mg/l). The variables studied at the end of the 215 days of rearing were as follows: final mean total length (26.61 ± 2.99 cm), final mean standard length (22.40 ± 2.74 cm), final mean predorsal length (6.93 ± 0.94 cm), final mean head length (3.45 ± 0.58 cm), final mean dorsal fin base length (13.55 ± 2.96 cm), final mean inter-orbital width (2.97 ± 0.37 cm), final mean body height (8.57 ± 1.56 cm) and final mean caudal peduncle height (3.27 ± 0.39 cm). The zootechnical growth parameters evaluated were as follows: survival rate (91.5%), final mean body weight (402.18 ± 137.05 g), average daily weight gain (1.83 ± 0.08 g), specific growth rate (0.77 ± 0.03%/day), feed conversion ratio (1.74 ± 0.09%) and protein efficiency ratio (1.62 ± 0.06). These results compared to the literature indicate interesting growth and body development and it would be important to promote in-cage farming of Oreochromis niloticus.

We filled most of that gap with a large spectroscopic and astrometric survey of targets towards σ Orionis. Eventually, it will be one of the open clusters with the lowest proportion of interlopers and the largest proportion of confirmed cluster members with known uncontrovertible youth features. Methods. We acquired 317 low-resolution optical spectra with the Intermediate Dispersion Spectrograph (IDS) at the 2.5 m Isaac Newton Telescope (INT) and the Optical System for Imaging and low Resolution Integrated Spectroscopy (OSIRIS) at the 10.4 m Gran Telescopio Canarias (GTC). We measured equivalent widths of Li I, Hα, and other key lines from these spectra, and determined spectral types. We complemented this information with Gaia DR2 astrometric data and other features of youth (mid-infrared excess, X-ray emission) compiled with Virtual Observatory tools and from the literature. Results. Of the 168 observed targets, we determined for the first time spectral types of 39 stars and equivalent widths of Li I and Hα of 34 and 12 stars, respectively. We identified 11 close (ρ ≲ 3 arcsec) binaries resolved by Gaia, of which three are new, 14 strong accretors, of which four are new and another four have Hα emission shifted by over 120 km s−1, two juvenile star candidates in the sparse population of the Ori OB1b association, and one spectroscopic binary candidate. Remarkably, we found 51 non-cluster-members, 35 of which were previously considered as σ Orionis members and taken into account in high-impact works on, for example, disc frequency and initial mass function.

Abstract:

Abstract Genetic early-onset parkinsonism presenting from infancy to adolescence (≤21 years old) is a clinically diverse syndrome often combined with other hyperkinetic movement disorders, neurological and imaging abnormalities. The syndrome is genetically heterogeneous, with many causative genes already known. With the increased use of next-generation sequencing in clinical practice, there have been novel and unexpected insights into phenotype-genotype correlations and the discovery of new disease-causing genes. It is now recognized that mutations in a single gene can give rise to a broad phenotypic spectrum and that, conversely different genetic disorders can manifest with a similar phenotype. Accurate phenotypic characterization remains an essential step in interpreting genetic findings in undiagnosed patients. However, in the past decade, there has been a marked expansion in knowledge about the number of both disease-causing genes and phenotypic spectrum of early-onset cases. Detailed knowledge of genetic disorders and their clinical expression is required for rational planning of genetic and molecular testing, as well as correct interpretation of next-generation sequencing results. In this review we examine the relevant literature of genetic parkinsonism with ≤21 years onset, extracting data on associated movement disorders as well as other neurological and imaging features, to delineate syndromic patterns associated with early-onset parkinsonism. Excluding PRKN (parkin) mutations, >90% of the presenting phenotypes have a complex or atypical presentation, with dystonia, abnormal cognition, pyramidal signs, neuropsychiatric disorders, abnormal imaging and abnormal eye movements being the most common features. Furthermore, several imaging features and extraneurological manifestations are relatively specific for certain disorders and are important diagnostic clues. From the currently available literature, the most commonly implicated causes of early-onset parkinsonism have been elucidated but diagnosis is still challenging in many cases. Mutations in ∼70 different genes have been associated with early-onset parkinsonism or may feature parkinsonism as part of their phenotypic spectrum. Most of the cases are caused by recessively inherited mutations, followed by dominant and X-linked mutations, and rarely by mitochondrially inherited mutations. In infantile-onset parkinsonism, the phenotype of hypokinetic-rigid syndrome is most commonly caused by disorders of monoamine synthesis. In childhood and juvenile-onset cases, common genotypes include PRKN, HTT, ATP13A2, ATP1A3, FBX07, PINK1 and PLA2G6 mutations. Moreover, Wilson’s disease and mutations in the manganese transporter are potentially treatable conditions and should always be considered in the differential diagnosis in any patient with early-onset parkinsonism.

Abstract:

Background:Few patients have been described in the literature with mutations in the Lacasa Domain containing one (LACC1) gene. Its clinical presentation usually associates sustained systemic inflammation associated with chronic polyarticular erosive arthritis. Until now, there have been multiple treatments described to try to control the disease, however, they are generally unsuccessful in the long term.Objectives:Describe the clinical course of a patient as well as the different treatments usedMethods:Clinical chart reviewResults:Female 18-year-old born from a consanguineous Moroccan couple. Mother, brother and sister with similar conditions. She started at 3 years with fever, anemia, intense elevation of acute phase reactants and symmetric polyarthritis (knees, elbows, carps, shoulders, hands and ankles). Subsequent whole exome sequencing identified c.128_129delGT mutation in the LACC1/FAMIN gene. During the course of her illness, she has received treatment with oral, intravenous and infiltrated corticosteroid, methotrexate and etanercept, without getting adequate control of the disease. In 2016, she started treatment with tocilizumab (8 mg / kg every two weeks), obtaining an acceptable control of the disease (requiring periodic infiltrations every 2-3 months due to persistent arthritis). Nonetheless, in April 2019, she consulted for clinical worsening of the arthritis and laboratory test (C reactive protein 99.7 mg / L, erythrosedimentation rate 53 mm / h, leukocytes 13,500/µL and neutrophils 10,930/µL). At that time, she discontinued therapy with tocilizumab and started tofacitinib 5 mg every 12 hours with good evolution. Since its introduction, it has not required joint infiltration again and the inflammatory parameters (persistently elevated previously) have normalized.Conclusion:The jak kinasa inhibitors may be a treatment option in those patients with bad response to conventional therapy.References:[1]Rabionet R, Remesal A, Mensa-Vilaró A, Murías S, Alcobendas R, González-Roca E, Ruiz-Ortiz E, Antón J, Iglesias E, Modesto C, Comas D, Puig A, Drechsel O, Ossowski S, Yagüe J, Merino R, Estivill X, Arostegui JI.

Abstract:

A paralisia bulbar progressiva, também denominada doença de Fazio-Londe, caracteriza-se pelo acometimento degenerativo progressivo de nervos cranianos bulbares em crianças. Foi descrita primeiramente por Fazio em 1892 e até a presente data somente 30 casos foram relatados na literatura. Acomete ambos os sexos, assumindo dois padrões clínicos, um de início precoce (idade <6 anos, predomínio de comprometimento respiratório) e outro de início tardio (6-20 anos, predomínio de comprometimento motor nos membros superiores). Descrevemos o caso de um menino com 4 anos, cujo primeiro sintoma foi estridor e disfunção respiratória grave, tendo inicialmente recebido diagnóstico de asma brônquica. O quadro evoluiu progressivamente, em aproximadamente 12 meses, para paralisia do V, VII, VIII, IX e X nervos cranianos, comprovada por acompanhamento clínico, exame físico e estudo eletrofisiológico de tronco cerebral.

Abstract:

RESUMO As características silviculturais e tecnológicas favoráveis da espécie Calophyllum brasiliense Camb. têm levado ao surgimento de plantios comerciais. De modo geral, a literatura apresenta somente dados médios e gerais sobre algumas variáveis desta espécie, não informando dados específicos a determinadas variáveis antecessoras ao momento do estudo tecnológico, como idade, espaçamento, entre outros, talvez porque se trata de uma espécie de floresta nativa. Dada a lacuna existente quanto à caracterização da madeira de guanandi, o objetivo deste trabalho foi estudar quantitativamente: (i) a variação estrutural morfológica das principais células do lenho, e (ii) a delimitação entre madeira juvenil e adulta, para a espécie proveniente de plantio puro, cujas variáveis antecessoras são conhecidas. Foram amostradas cinco espécimes, dentro de uma população de 135 árvores, com 13 anos de idade e espaçamento 4,0 m x 2,5 m. Os resultados indicaram valores médios de 1134; 21,02; 12,88 e 4,07 μm para o comprimento, largura, diâmetro do lume e espessura média da parede das fibras, respectivamente. A madeira de guanandi com 13 anos de idade foi caracterizada como juvenil.

Pretendemos usá-las para trabalhar, intratextualmente, a personagem do adolescente que, no mesmo dia, experiencia a perda do avô e o seu primeiro beijo num violento choque de emoções; e, paratextualmente, descodificar a materialização da leitura literária que, através do texto de Ana Pessoa e da ilustração de Bernardo P. Carvalho, se faz jogando também com as dificuldades em lutar com o peso gravitacional do lugar e do tempo na adolescência. Joga-se com a intensidade, a velocidade, do tempo de ser e de dizer, tudo em excesso. Edgar, protagonista e narrador, é um corpo que adolesce abruptamente como numa explosão cósmica.

Abstract:

The objective of the present study was to analyze diel variation in the abundance and size of the seabob shrimp Xiphopenaeus kroyeri in the Ubatuba region, state of São Paulo, during the year 2000. In each season of the year, collections were made in the day and at night on 9 transects at depths ranging from 2 to 40 m. The estimated shrimp amount was of 28,878 individuals. Although the catch rate was higher during the day (15,853 shrimp), this did not differ significantly from the catch at night (13,025). The catch rate was higher in daytime on most transects, but was higher at night at locations where fine and very fine sand predominated. The majority of juveniles were caught during the day. The mean size (CL) was 14.43 ± 4.02 mm for day and 14.82 ± 4.28 mm for night samples, and the difference was significant (Student's t-test, df = 2, 429, t = 2.27, p = 0.02). The largest individuals were caught during the night. None of the three models that have been proposed in the literature to account for differences in the diurnal catch pattern of penaeid species can be applied to X. kroyeri. Our results provide evidence that sediment type not only influenced the catch rate in the analyzed periods, but also determined which models might fit the behavior of this species.

Abstract:

Background:Since the beginning of the COVID-19 pandemic in our country, Turkey, more than two million people have been infected and more than 20,000 people have died. Although children infected less frequently and generally have a milder findings of COVID-19, the number of patients with a more severe clinical course as multisystem inflammatory syndrome in children (MIS-C) is increasing significantly. However, it has not been shown exactly how biological disease-modifying antirheumatic drug (bDMARD)s, which we frequently use in our pediatric rheumatology practice, and/or the underlying rheumatological diseases affect the clinical course of COVID-19.Objectives:Here, we aimed to reveal the outcome of COVID-19 infection in our patients with pediatric rheumatic disease and treated with bDMARDs.Methods:During the period between April 1, 2020 and December 1, 2020, the patients who received bDMARDs were evaluated at the regular outpatient clinic follow-up or by telemedicine with a maximum of 3 months interval. Clinical and demographic characteristics, COVID-19 data and outcome of these patients were retrospectively collected.Results:Out of the 436 patients treated with bDMARDs, 39 children were infected with COVID-19. The diagnosis was confirmed in 37 patients by RT-PCR (nasalpharyngeal swab) and in two by antibody test. Twenty-two (56.4%) patients were female (17 male, %43.6) and the median age of patients were 12.3 years (min-max: 1.2-20.9). The primary diagnosis of patients were as follows; 20 juvenile idiopathic arthritis (six were systemic subtype), 12 systemic autoinflammatory diseases, three vasculitis, three chronic recurrent multifocal osteomyelitis and one Sjögren’s syndrome. Prior to COVID-19 infection, 13 patients (33.3%) were using canakinumab, seven were infliximab (18%), five were adalimumab (12.8%), four were etanercept 10.2%), four were tocilizumab (10.2%), three were anakinra (7.7%), two were rituximab (5.1%), and one was tofacitinib (2.6%).Of the 39 patients, 21 had at least one COVID-19-related symptom, while 18 patients were asymptomatic. No laboratory or imaging tests was performed for asymptomatic patients and they were followed up without treatment at home isolation. Laboratory tests revealed that fourteen patients had elevated acute phase reactants, six had elevated D-dimer levels, three had lymphopenia (<1000/mm3), and three had hyperferritinemia.Hospitalization was required in 20 patients (51.3%) at median of 7-days (min-max: 3-17) and pediatric intensive care unit admission in one. Five patients developed MIS-C and one of these patients was followed up in the pediatric intensive care unit. Myocardial dysfunction was developed in this patient and he was died. The other four patients fully recovered with no remain morbidity.Conclusion:Considering the literature data and the results of our study, it is not possible to say that currently used bDMARDs worse the course of COVID-19 infection. In patients with underlying risk factors for hyperinflammation, as in one of our patients, COVID-19 may cause mortality regardless of the use of bDMARDs. Whether bDMARDs does not affect the severity of the disease, but it is still not true to say that these drugs are protective. Since cessation of bDMARDs for COVID-risk may cause exacerbation of the primary rheumatic disease, continuing with current treatments seems an appropriate approach.References:[1]FELDSTEIN LR, ROSE EB, HORWITZ SM, et al: Overcoming COVID-19 Investigators; CDC COVID-19 Response Team.

Abstract:

The virulence of aerial conidia of the entomopathogenic fungi Beauveria bassiana (Balsamo-Crivelli) Vuillemin (Hypocreales: Cordycipitaceae) has been documented on a very broad range of arthropods; however, the activity of blastospores against the two-spotted spider mite has been seldomly reported. Moreover, studies investigating the activity of blastospores under greenhouse conditions were not found in the literature. In this study, we tested the efficacy of blastospores and aerial conidia of two B. bassiana strains, against all life stages of Tetranychus urticae Koch (Acari: Tetranychidae). The concentration of 109 blastospores/ml of the Lebanese strain was the most efficient in laboratory experiments, and the recorded mortalities were 52, 67.9 and 95.3% in treated eggs, motile juveniles and adults, respectively. In greenhouse experiments, higher T. urticae mortalities were recorded among strawberry plants (Fragaria x ananassa) sprayed with blastospores of B. bassiana. Furthermore, the latter plants also recorded a higher yield (454.92 ± 5 g/plant) compared to infested control plants (144.42 ± 5 g/plant) during the growing season. In addition, this study also investigated for the first time the resistance development of T. urticae to different types of infective propagules of B. bassiana. Under selective pressure for 40 generations, the laboratory yielded aerial conidia (AC-TSM) and blastospores (BS-TSM) resistant strains of the mite recorded 28.8- and 8.4- fold change in LC50 values respectively when compared to the field strain; however, this resistance ratio was minimal when compared to those of chemical acaricides.

Abstract:

Reefs, mangroves and seagrass biotopes often occur in close association, forming a complex and highly productive ecosystem that provide significant ecologic and economic goods and services. Different anthropogenic disturbances are increasingly affecting these tropical coastal habitats leading to growing conservation concern. In this field-based study, we used a visual census technique (belt transects 50 m x 2 m) to investigate the interactions between fishes and microhabitats at the Mamanguape Mangrove-Reef system, NE Brazil. Overall, 144 belt transects were performed from October 2007 to September 2008 to assess the structure of the fish assemblage. Fish trophic groups and life stage (juveniles and adults) were recorded according to literature, the percent cover of the substrate was estimated using the point contact method. Our results revealed that fish composition gradually changed from the Estuarine to the Reef zone, and that fish assemblage was strongly related to the microhabitat availability, as suggested by the predominance of carnivores at the Estuarine zone and presence of herbivores at the Reef zone. Fish abundance and diversity were higher in the Reef zone and estuary margins, highlighting the importance of structural complexity. A pattern of nursery area utilization, with larger specimens at the Transition and Reef Zone and smaller individuals at the Estuarine zone, was recorded for Abudefduf saxatilis, Anisotremus surinamensis, Lutjanus alexandrei, and Lutjanus jocu. Our findings clearly suggests ecosystem connectivity between mangrove, seagrass and reef biotopes, and highlighted the importance of Mamanguape Mangrove-Reef System as a priority area for conservation and research, whose habitat mosaics should be further studied and protected.
