Resumo Introdução: A Atenção Primária à Saúde (APS) representa o primeiro elemento de uma rede de processos de atenção à saúde que tem na Estratégia Saúde da Família o alicerce para a sua reorganização, expansão e consolidação. Objetivo: Investigar a efetividade do apoio matricial (AM) realizado pelos fisioterapeutas para os agentes comunitários de saúde (ACS) em relação ao nível de conhecimento sobre condições de saúde sensíveis à atuação da fisioterapia na APS. Métodos: Trata-se de um estudo quase-experimental realizado com dois grupos de ACS, divididos em controle (n = 6) e intervenção (n = 7), totalizando 13 profissionais pertencentes a um município de pequeno porte. O AM aconteceu por meio de oficinas educativas, abordando os temas maternoinfantil, adulto, idoso e desordens musculoesqueléticas. Para a avaliação inicial foram aplicados um questionário semiaberto com dados sociodemográficos e questões relacionadas ao trabalho, um questionário estruturado contendo questões relacionadas à atuação da fisioterapia na APS, que apresentava situações da rotina de trabalho do ACS, e um inquérito semiaberto de investigação de pacientes a serem encaminhados para a fisioterapia. Para a avaliação final, os mesmos instrumentos foram reaplicados, exceto o questionário sociodemográfico. Resultados: Após o AM, na comparação entre os grupos, houve diferença estatística no índice de percepção de risco no eixo das desordens musculoesqueléticas (p = 0,032) e na identificação de casos de alterações infantis (p = 0,012). Na comparação intragrupo, o grupo intervenção apresentou diferença estatística na percepção de risco na saúde do idoso e na maioria dos itens do inquérito de encaminhamentos (p < 0,05 para todos). Conclusão: O AM pode contribuir para a construção compartilhada de saberes, bem como para o acionamento da fisioterapia na APS pelos ACS.

Abstract Introduction: Primary health care (PHC) represents the first step of a network of health care processes that have the Family Health Strategy as their foundation for reorganization, expansion and consolidation. Objective: To investigate the effectiveness of the matrix support provided by the physical therapist to the community health agents (CHAs) regarding the level of knowledge about health conditions responsive to the performance of physiotherapy in PHC. Methods: We conducted a quasi-experimental study with two groups of CHAs, divided into control (n = 6) and intervention (n = 7), totaling 13 professionals belonging to a small municipality. Matrix support took place through educational workshops, addressing the axes of maternal and child health, adult health, health of older people and musculoskeletal disorders. For the initial assessment, a semi-open questionnaire was administered with sociodemographic data and work-related questions, a structured questionnaire containing questions related to the performance of physiotherapy in PHC that presents situations from the CHA's work routine, and a semi-open survey investigating patients to be referred to physiotherapy. For the final assessment, the same instruments were reapplied, except for the sociodemographic questionnaire. Results: After the intervention, in the comparison between groups, there was a difference in the risk perception index in the axis of musculoskeletal disorders (p = 0.032) and in the identification of cases of childhood changes (p = 0.012). In the intragroup comparison, the intervention group showed a difference in risk perception in the health of the older persons and in most of the items of the referral survey (p < 0.05 for all). Conclusion: Matrix support can contribute to the shared construction of knowledge, as well as to the activation of physiotherapy in PHC by CHAs.

RESUMO JUSTIFICATIVA E OBJETIVOS: A amputação é um evento que acarreta consequências que podem afetar o cotidiano, entre elas a dor, potencializando alterações, seja no sono ou na qualidade de vida. O objetivo deste estudo foi avaliar o limiar de dor por pressão (LDP) em pessoas com amputação submetidas ao uso de diferentes equipamentos de elevação postural. MÉTODOS: Estudo experimental cruzado, realizado de setembro a outubro de 2022, com pessoas com amputação no membro inferior (n=15) e pessoas sem amputação (n=15). Foram avaliados o LDP em quatro regiões (T12-L1, L5-S1, tuberosidade anterior da tíbia e calcâneo) pré e pós uso de distintas versões (A e B) de um equipamento de elevação postural, gravidade e interferência da dor. Presença de sinais e sintomas de sensibilização central (SC) e qualidade do sono. RESULTADOS: Os grupos não apresentaram alterações no LDP quando comparados em relação às diferentes versões do equipamento (p<0,05) nos quatro locais analisados. Além disso, os grupos não mostraram diferenças em relação aos dias de avaliação ou entre si quanto a severidade e interferência de dor e presença de sinais e sintomas de SC. O grupo controle indicou uma qualidade de sono ruim (p=0,0173) e manteve-se pior que as pessoas com amputação. CONCLUSÃO: As versões do equipamento não alteraram o LDP nas áreas analisadas. Os grupos não apresentaram diferença entre si, sugerindo que o equipamento promoveu respostas semelhantes, ou seja, não foi evidenciada uma alteração de sensibilidade nas regiões que possuem maior contato com elementos de estabilização e descarga de peso dos equipamentos.

ABSTRACT BACKGROUND AND OBJECTIVES: Amputation is an event that has consequences that can affect daily life, including pain, enhancing changes, whether in sleep or in quality of life. The objective of this study was to evaluate the pressure pain threshold (PPT) in people with amputations submitted to the use of different postural elevation equipment. METHODS: Experimental crossover study, carried out from September to October 2022, with people with lower limb amputation (n=15) and people without amputation (n=15). PPT in four regions (T12-L1, L5-S1, anterior tuberosity of the tibia and calcaneus) were evaluated before and after the use of different versions (A and B) of an equipment for postural elevation, gravity and pain interference. Presence of signs and symptoms of central sensitization (CS) and sleep quality. RESULTS: The groups did not present PPT alterations when compared between the different versions of the equipment (p<0.05) in the four locations analyzed. Furthermore, the groups did not show differences in relation to the evaluation days or among themselves regarding the severity and interference of pain and the presence of signs and symptoms of CS. The control group indicated poor sleep quality (p=0.0173) and remained worse than people with amputation. CONCLUSION: The versions of the equipment did not change PPT in the analyzed areas. The groups did not differ between themselves, suggesting that the equipment promoted similar responses, that is, no change in sensitivity was evidenced in the analyzed regions which have greater contact with stabilization elements and weight discharge of the equipment.

ABSTRACT Objective: Adipose tissue-derived stromal/stem cells (ASCs) and vitamin D have immunomodulatory actions that could be useful for type 1 diabetes (T1D). We aimed in this study to investigate the safety and efficacy of ASCs + daily cholecalciferol (VIT D) for 6 months in patients with recent-onset T1D. Materials and methods: In this prospective, dual-center, open trial, patients with recent onset T1D received one dose of allogenic ASC (1 x 106 cells/kg) and cholecalciferol 2,000 UI/day for 6 months (group 1). They were compared to patients who received chol-ecalciferol (group 2) and standard treatment (group 3). Adverse events were recorded; C-peptide (CP), insulin dose and HbA1c were measured at baseline (T0), after 3 (T3) and 6 months (T6). Results: In group 1 (n = 7), adverse events included transient headache (all), mild local reactions (all), tachycardia (n = 4), abdominal cramps (n = 1), thrombophlebitis (n = 4), scotomas (n = 2), and central retinal vein occlusion at T3 (n = 1, resolution at T6). Group 1 had an increase in basal CP (p = 0.018; mean: 40.41+/-40.79 %), without changes in stimulated CP after mixed meal (p = 0.62), from T0 to T6. Basal CP remained stable in groups 2 and 3 (p = 0.58 and p = 0.116, respectively). Group 1 had small insulin requirements (0.31+/- 0.26 UI/kg) without changes at T6 (p = 0.44) and HbA1c decline (p = 0.01). At T6, all patients (100%; n = 7) in group 1 were in honeymoon vs 75% (n = 3/4) and 50% (n = 3/6) in groups 2 and 3, p = 0.01. Conclusions: Allogenic ASC + VIT D without immunosuppression was safe and might have a role in the preservation of β-cells in patients with recent-onset T1D. ClinicalTrials.gov: NCT03920397.

ABSTRACT Objectives: American Thyroid Association (ATA)'s new guidelines recommend use of population-based trimester-specific reference range (RR) for thyrotropin (TSH) in pregnancy. The aim of this study was to determine first trimester TSH RR for a population of pregnant women in Rio de Janeiro State. Subjects and methods: Two hundred and seventy pregnant women without thyroid illness, defined by National Academy of Clinical Biochemistry, and normal iodine status were included in this sectional study. This reference group (RG) had normal median urinary iodine concentration (UIC = 219 μg/L) and negative anti-thyroperoxidase antibodies (TPOAb). Twin pregnancy, trophoblastic disease and use of drugs or supplements that influence thyroid function were excluded. In a second step, we defined a more selective reference group (SRG, n = 170) by excluding patients with thyroiditis pattern on thyroid ultrasound and positive anti-thyroglobulin antibodies. This group also had normal median UIC. At a final step, a more selective reference group (MSRG, n = 130) was defined by excluding any pregnant women with UIC < 150 μg/L. Results: In the RG, median, 2.5th and 97.5th percentiles of TSH were 1.3, 0.1, and 4.4 mIU/L, respectively. The mean age was 270 ± 5.0 and the mean body mass index was 25.6 ± 5.2 kg/m2. In the SRG and MSRG, 2.5th and 975th percentiles were 0.06 and 4.0 (SRG) and 0.1 and 3.6 mIU/L (MSRG), respectively. Conclusions: In the population studied,TSH upper limit in the first trimester of pregnancy was above 2.5 mIU/L. The value of 3.6 mIU/L, found when iodine deficiency and thyroiditis (defined by antibodies and ultrasound characteristics) were excluded, matches recent ATA guidelines.

Vários trabalhos de avaliação de eficiência no uso de nitrogênio (EUN) já foram feitos utilizando estádios precoces. Contudo, não há relatos científicos sobre o estádio ideal e, neste, quais caracteres que apresentam maior correlação com a EUN. Assim, o objetivo foi identificar os estádios fenológicos e os caracteres secundários que maximizam a acurácia na seleção precoce e indireta para a EUN em milho. Para isso, foram avaliadas três linhagens endogâmicas de milho em delineamento inteiramente casualizado, com cinco repetições, em esquema fatorial triplo (linhagens x níveis de N x estádio fenológico), em duas doses contrastantes de nitrogênio - baixo e alto nitrogênio. As plantas foram avaliadas em cinco estádios fenológicos sendo eles: nove (V9) e 14 folhas completamente desenvolvidas (V14), pendoamento (VT), florescimento (R1) e maturidade fisiológica (R6). Foram avaliados os caracteres: eficiência na utilização, na absorção, no uso e na translocação de nitrogênio, atividade da nitrato redutase e da glutamina sintetase, comprimento de raiz lateral e axial, área de raiz específica, teor de clorofila, número de folhas, altura de planta, diâmetro de colmo, teor de fósforo e potássio. Considerando os ganhos diretos e indiretos estimados, conclui-se que as atividades da glutamina sintetase, nos estádios V9 e V14, permitem a seleção precoce e indireta para eficiência no uso de nitrogênio em milho, nas condições de baixa e alta disponibilidade de N, respectivamente.

Several studies to evaluate nitrogen use efficiency (NUE) have been carried out using early growth stages. However, there are no scientific reports on the ideal stage for evaluation and on which characteristics have the highest correlation with the NUE at that stage. The aim therefore was to identify the phenological stages and secondary characteristics which maximize accuracy in early indirect selection for NUE in maize. To do this, three endogamic maize strains were evaluated in a completely randomised design with five replications, in a triple factorial scheme (strains x N levels x phenological stage), at two contrasting nitrogen levels: low and high nitrogen. The plants were evaluated at five growth stages: stage nine (V9), with 14 fully-developed leaves (V14), tasseling (VT), flowering (R1) and physiological maturity (R6). The following characteristics were evaluated: efficiency in the usage, absorption, use and translocation of nitrogen; activity of nitrate reductase and glutamine synthetase; length of the lateral and axial roots; specific root area; chlorophyll content; number of leaves; plant height; stem diameter; and the levels of phosphorus and potassium. Considering the estimated direct and indirect gains, it can be concluded that the activities of glutamine synthetase at the V9 and V14 stages permit early indirect selection for nitrogen use efficiency in maize under conditions of low and high N availability respectively.

The objective of this study was to evaluate intake, digestibility and nitrogen (N) compounds use efficiency in F1 Holstein × Zebu grazing cows. Eighteen crossbred cows (six Holstein × Gir, six Holstein × Guzerat, and six Holstein × Nellore) were used in the experiment, constituting three experimental treatments in simple random samples, under the same feeding conditions. At the estimation of individual intake at grazing, titanium dioxide was used for estimating fecal excretion and indigestible neutral detergent fiber, in order to determine pasture intake. There was effect of the lactation period on nutrient intake, except for the intakes of dry matter (DM), organic matter (OM) and total digestible nutrients (TDN) in % of body weight (BW), as well as those of non-fibrous carbohydrates (NFC), in kg. The digestibility coefficients of crude protein (CP), neutral detergent fiber corrected for ash and protein (NDFap) and the contents of TDN varied in function of the lactation period, whereas the coefficients of digestibility of DM, ether extract (EE) and OM did not present such effect. The total milk production projected at 305 days of lactation for Holstein × Gir cows was superior in relation to Holstein × Guzerat and Holstein × Nellore cows. The excretion of urea into urine and of urea N into the milk and the plasma presented quadratic behavior in function of the lactation period. The utilization of the genetic group from Holstein × Zebu grazing cows does not cause alterations in intake, nutrient digestibility or nitrogen use efficiency; however, there is variation in function of the lactation period. Holstein × Gir cows presented greater accumulated production during lactation and persistence, followed by Holstein × Guzerat and Holstein × Nellore cows.

In a previous study, the Schistosoma mansoni Rho1 protein was able to complement Rho1 null mutant Saccharomyces cerevisiae cells at restrictive temperatures and under osmotic stress (low calcium concentration) better than the human homologue (RhoA). It is known that under osmotic stress, the S. cerevisiae Rho1 triggers two distinct pathways: activation of the membrane 1,3-beta-glucan synthase enzymatic complex and activation of the protein kinase C1 signal transduction pathway, promoting the transcription of response genes. In the present work the SmRho1 protein and its mutants smrho1E97P, smrho1L101T, and smrho1E97P, L101T were used to try to clarify the basis for the differential complementation of Rho1 knockout yeast strain by the human and S. mansoni genes. Experiments of functional complementation in the presence of caffeine and in the presence of the osmotic regulator sorbitol were conducted. SmRho1 and its mutants showed a differential complementation of the yeast cells in the presence of caffeine, since smrho1E97P and smrho1E97P, L101T mutants showed a delay in the growth when compared to the yeast complemented with the wild type SmRho1. However, in the presence of sorbitol and caffeine the wild type SmRho1 and mutants showed a similar complementation phenotype, as they allowed yeast growth in all caffeine concentrations tested.

The human nuclear protein RbAp48 is a member of the tryptophan/aspartate (WD) repeat family, which binds to the retinoblastoma (Rb) protein. It also corresponds to the smallest subunit of the chromatin assembly factor and is able to bind to the helix 1 of histone H4, taking it to the DNA in replication. A cDNA homologous to the human gene RbAp48 was isolated from a Schistosoma mansoni adult worm library and named SmRbAp48. The full length sequence of SmRbAp48 cDNA is 1036 bp long, encoding a protein of 308 amino acids. The transcript of SmRbAp48 was detected in egg, cercariae and schistosomulum stages. The protein shows 84% similarity with the human RbAp48, possessing four WD repeats on its C-terminus. A hypothetical tridimensional structure for the SmRbAp48 C-terminal domain was constructed by computational molecular modeling using the b-subunit of the G protein as a model. To further verify a possible interaction between SmRbAp48 and S. mansoni histone H4, the histone H4 gene was amplified from adult worm genomic DNA using degenerated primers. The gene fragment of SmH4 is 294 bp long, encoding a protein of 98 amino acids which is 100% identical to histone H4 from Drosophila melanogaster.
