Peripheral muscle oxygenation, pain, and disability indices in individuals with and without nonspecific neck pain, before and after myofascial reorganization®: A double-blind randomized controlled trial.

To investigate whether myofascial reorganization® in the trapezius muscle (MRT) improves peripheral muscle oxygenation and pain tolerance and decreases neck disability index (NDI) scores in individuals with and without nonspecific neck pain (NP) using a double-blind randomized controlled trial. Seventy-five subjects were equally and randomly assigned to three groups: the intervention groups (experimental [EG] and sham sSG]) and the control group (CG). Several inclusion criteria were applied to the intervention groups: male or female, aged 18-32 years, self-reported NP in the last 3 months without a defined cause; at least "soft" pain in session 1 of the NDI, and at least a score of 1 on the Visual Analogue Scale (VAS). The CG was required to have NDI and VAS scores of 0 at recruitment. Intervention: The EG underwent MRT for 10 min, once a week for 6 weeks. Patients with NP in the SG underwent classical massage for the same duration and frequency. Patients in the CG had no pain and underwent no intervention. Data collection was performed using the NDI Questionnaire, a pressure algometer for pain evaluation, and near-infrared spectroscopy for muscle oxygenation measurements. It was registered as NCT03882515 at ClinicalTrials.gov. The NDI score in both the EG (p<0.001) and SG (p<0.001) decreased after 6 weeks of intervention compared to the CG. The CG demonstrated a lower basal tissue saturation (TSI) index than the EG (p<0.001) and SG (p = 0.02). The EG demonstrated higher oxyhemoglobin values than the SG (p<0.001) and CG (p = 0.03). The CG had higher pain tolerance than the EG (p = 0.01) and SG (p<0.001) post-intervention. MRT increased trapezius muscle oxygenation after 6 weeks of intervention.

Assistência pré-natal e resultado perinatal / Prenatal care and perinatal outcome / Atención prenatal y resultado perinatal

Objetivo: Relacionar o número de consultas de pré-natal aos desfechos perinatais. Métodos: Realizou-se um estudo de corte transversal, no período de setembro de 2014 a agosto de 2015, em base de dados de gestantes de uma maternidade pública na cidade de Joinville/SC/Brasil. A pesquisa incluiu pacientes com gestação única, subdividindo-os em 2 grupos: com 6 ou menos e 7 ou mais consultas de pré-natal. Utilizaram-se os desfechos primários: via de parto, prematuridade, baixo peso ao nascer, macrossomia, óbito perinatal. Analisou-se com modelo de regressão logística multinomial, com intervalo de confiança de 95%. Resultados: Obtiveram-se 4.260 prontuários, 266 (6,2%) realizaram 6 consultas ou menos e 3.994 (93,7%) com 7 consultas ou mais de pré-natal. Os grupos apresentaram diferença nas características maternas; na idade, menor ou igual a 20 anos (27,4% vs 21,3% p=0,020) entre os grupos; na escolaridade, respectivamente primeiro grau incompleto (28,1% vs 21% p=0,006) e segundo grau completo (25,9% vs 36,9% p= 0,000); hipertensão arterial sistêmica (9,77% vs 6,5% p=0,039), diferentes características neonatais, como prematuridade (23,6% vs 6,6% p=0,000), e no parto a termo (76,3%) vs 93,3% p= 0,000) respectivamente. Encontrou-se maior chance de prematuridade (OR= 2,837), baixo peso (OR=1,895) e óbito perinatal (OR=5,584) no grupo que realizou 6 consultas ou menos. Conclusão: As gestantes com menos de sete consultas de pré-natal têm maior chance de ocorrência de prematuridade, baixo peso ao nascer e óbito perinatal.

Objective: To relate the number of prenatal consultations to perinatal outcomes. Methods: Cross-sectional study conducted from September 2014 to August 2015 using a database of pregnant women attending a public maternity hospital in the city of Joinville, Santa Catarina, Brazil. The research included single pregnancy patients divided into 2 groups: a group of 6 or less prenatal consultations and a group of 7 or more prenatal consultations. The following primary outcomes were analyzed: delivery method, prematurity, low birth weight, macrosomia, perinatal death. The analysis was carried out using a multinomial logistic regression model with a 95% confidence interval. Results: In all, 4,260 records were analyzed: 266 (6.2%) had 6 or less prenatal consultations and 3,994 (93.7%) had 7 or more prenatal consultations. The groups presented different maternal characteristics ­ age ≤20 years (27.4% vs 21.3% p=0.020), incomplete primary education (28.1% vs 21% p=0.006) and complete secondary education (25.9% vs 36.9% p=0.000), systemic arterial hypertension (9.77% vs 6.5% p=0.039) ­ and different neonatal characteristics ­ prematurity (23.6% vs. 6.6%, p=0.000) and full-term birth (76.3% vs 93.3% p=0.000). The group of women who had 6 consultations of less was at increased odds of prematurity (OR=2.837), low birth weight (OR=1.895) and perinatal death (OR=5.584). Conclusion: The pregnant women who had less than seven prenatal consultations are at increased odds of prematurity, low birth weight and perinatal death.

Objetivo: Relacionar el número de consultas prenatales con los desenlaces perinatales. Métodos: Se realizó un estudio de cohorte transversal en el período entre septiembre de 2014 y agosto de 2015 en las bases de datos de embarazadas de una maternidad pública de la ciudad de Joinville/SC/Brasil. La investigación incluyó pacientes de única gestación dividiéndose en 2 grupos: con 6 o menos y 7 o más consultas prenatales. Se utilizaron los siguientes desenlaces primarios: la vía del parto, la prematuridad, el bajo peso al nacer, la macrosomía y el óbito perinatal. El análisis se realizó con el modelo de regresión logística multinomial con el intervalo de confianza del 95%. Resultados: De un total de 4.260 historiales clínicos, 266 (6,2%) pacientes realizaron 6 consultas o menos y 3.994 (93,7%) tuvieron 7 consultas prenatal o más. Los grupos presentaron diferencia en las características maternas; con edad de 20 años o menos (27,4% vs 21,3% p=0,020) entre los grupos; con educación básica incompleta (28,1% vs 21% p=0,006) y educación secundaria completa (25,9% vs 36,9% p= 0,000); hipertensión arterial sistémica (9,77% vs 6,5% p=0,039), distintas características neonatales como la prematuridad (23,6% vs 6,6% p=0,000) y en el parto a término (76,3%) vs 93,3% p= 0,000) respectivamente. Se encontró más oportunidad de prematuridad (OR= 2,837), bajo peso (OR=1,895) y óbito perinatal (OR=5,584) en el grupo que realizó 6 consultas o menos. Conclusión: Las gestantes con menos de siete consultas prenatales tienen más oportunidad de prematuridad, bajo peso al nascer y óbito perinatal.
