a systematic review with meta-analysis

Publisher Copyright: © 2024 The AuthorsBackground: Therapeutic exercise has been considered a useful tool to rehabilitate shoulder pain, namely through its influence on scapular dynamics. Accordingly, the effectiveness of scapular therapeutic exercise needs to be explored. The present study aims to evaluate the effectiveness of scapular therapeutic exercises in shoulder pain and to identify the most effective exercise type (focal or multijoint) and ways of delivering them (as dose and progression). Methods: Search was conducted at EMBASE, Cochrane Library, MEDLINE via PubMed, Web of Science, PEDro (Physiotherapy Evidence Database), and trial registration databases. The meta-analysis considered randomized controlled/crossover trials that compared the effect of scapular exercises against other types of intervention in the shoulder pain, shoulder function, scapular motion, and/or muscular activity. The risk of bias was assessed through the PEDro scale. Results: From the 8318 records identified, 8 (high to low risk of bias– scoring from 4 to 8 on the PEDro scale) were included. The overall data, before sensitivity analysis, indicated that the scapular therapeutic exercises are: a) more effective than comparators in improving shoulder function (standardized mean difference [SMD] = 0.52 [95% Cl: 0.05, 0.99], P = .03, I2 = 76%); and b) as effective as comparators in reducing shoulder pain (SMD = 0.32 [95% Cl: −0.09, 0.73], P = .13, I2 = 70%). Subgroup analysis revealed that scapular exercises are more effective in improving shoulder function when the program duration is equal to or higher than 6 weeks (SMD = 0.43 [95% Cl: 0.09, 0.76] P = .01, I2 = 21%) and/or when the maximum number of exercise repetitions per session is lower than 30 (SMD = 0.79 [95% Cl: 0.15, 1.42], P = .01, I2 = 77%). Only 1 study considered scapular motion as an outcome measure, revealing therapeutic exercise effectiveness to improve scapular range of motion. Conclusions: Intervention programs involving scapular therapeutic exercises are effective in improving shoulder function, presenting benefits when performed for 6 or more weeks and/or when used up to a maximum of 30 repetitions per exercise, per session.proofepub_ahead_of_prin

Effectiveness of specific scapular therapeutic exercises in patients with shoulder pain: a systematic review with meta-analysis

Prevalence of hemoglobinopathies in school children: the importance of using confirmatory methods

The hemoglobinopathies are included among the most common genetic diseases in the world. In Brazil, hemoglobinopathies are related to the diversity of racial backgrounds and the degree of interbreeding. The study focused on the prevalence of hemoglobinopathies using conventional and confirmatory laboratory tests in children from public schools in Ribeirão Preto-SP. The study involved the participation of 427 children between six and nine years of age. Hematologic evaluation, hemoglobin electrophoresis on cellulose acetate at alkaline pH, quantification of hemoglobin fractions by high performance liquid chromatography (HPLC) and detection of -α3.7 deletion for α thalassemia by polymerase chain reaction were performed. The results of hemoglobin electrophoresis on cellulose acetate and HPLC of the children studied showed the presence of 30 children (7%) with hemoglobinopathies. Eleven children presented results indicating suspicion of S/β-thalassemia; their parents and/or siblings were evaluated and confirmed the presence of only Hb S. The analysis of deletion -α3.7to characterize α-thalassemias sampling performed on 207 participants identified 26 children (12.6%) with deletion -α3.7. Thus, 54 (12.6%) of the children studied present this genetic alteration. For the detection of α-thalassemias it is necessary to use confirmatory methods such as molecular analysis and evaluation of family members in doubtful cases to facilitate genetic counseling in families, in which deletion -α3.7 is more frequent in Brazil.</p

Caracterização clínica e laboratorial de cães naturalmente infectados com Trypanosoma cruzi no semiárido nordestino

Objetivou-se, com este estudo, evidenciar os sinais clínicos e laboratoriais desta enfermidade para auxiliar na caracterização da doença de forma natural na área semi-árida da região nordeste. Foram avaliados 10 cães positivos para Trypanosoma cruzi, identificados mediante análises sorológicas de reação de imunofluorescência indireta (RIFI) e enzyme linked immunosorbent assay (ELISA); análise molecular pela Reação em Cadeia Polimerase (PCR), microscopia direta e hemocultura. Os cães chagásicos foram submetidos à avaliação física, verificação da pressão arterial, exames eletrocardiográficos, radiográficos, hematológicos (eritrograma e leucograma) e bioquímicos (ureia, creatinina, ALT, AST, PT, albumina, globulina, CK, CK-MB e cTnI). O exame físico e os valores das pressões arteriais dos cães apresentaram dentro dos parâmetros de normalidade, enquanto que na eletrocardiografia observou-se FC normal com ritmo sinusal, com exceção de um cão, que apresentou taquicardia sinusal (168 bat/min). No ECG de oito cães houve aumento da duração de P (47±6,5ms) sugestivo de aumento atrial, não confirmado radiograficamente. Foi observado supradesnivelamento do segmento ST em um cão. Nos resultados hematológicos constatou-se trombocitopenia (187,4x10³ ±137,2x10³) e anemia (5,0x10(6) ±1,39x10(6)/uL). Os valores médios da hemoglobina (11±2,7g/dL) e do hematócrito (34±10,5%) estavam abaixo dos limites de normalidade. A série branca apresentou-se dentro dos limites de normalidade, com exceção da eosinofilia observada em três cães. Individualmente, registrou-se em dois cães, leucocitose, linfocitose e neutrofilia. Na avaliação bioquímica, registrou-se hiperproteinemia (7,2±0,9g/dL), hipoalbuminemia (2,2±0,4g/dL), hiperglobulinemia (5,1±1,0g/dL) e aumento da CK (196±171U/L). Não houve alteração nas enzimas ALT e AST. A isoenzima CK-MB e o cTnI alteraram somente em três cães. Os cães infectados naturalmente no semiárido nordestino apresentam características relacionáveis à forma crônica indeterminada, ou seja, cães assintomáticos. A identificação dos cães infectados naturalmente sem características patognomônicas da doença de Chagas ressalta a importância desta enfermidade no processo diagnóstico com as demais que manifestam perfis inespecíficos associados ou não às doenças cardiovasculares
