Risk Factors for Intrapartum Cesarean Section Delivery in Low-risk Multiparous Women Following at Least a Prior Vaginal Birth (Robson Classification 3 and 4)

Abstract Objective The aim of the present study was to evaluate the risk factors for cesarean section (C-section) in low-risk multiparous women with a history of vaginal birth. Methods The present retrospective study included low-risk multiparous women with a history of vaginal birth who gave birth at between 37 and 42 gestational weeks. The subjects were divided into 2 groups according to the mode of delivery, as C-section Group and vaginal delivery Group. Risk factors for C-section such as demographic characteristics, ultrasonographic measurements, smoking, weight gain during pregnancy (WGDP), interval time between prior birth, history of macrosomic birth, and cervical dilatation at the admission to the hospital were obtained fromthe charts of the patients. Obstetric and neonatal outcomes were compared between groups. Results The most common C-section indications were fetal distress and macrosomia (33.9% [n=77 and 20.7% [n=47] respectively). A bivariate correlation analysis demonstrated that mothers aged>30 years old (odds ratio [OR]: 2.09; 95% confidence interval [CI]: 1.30-3.34; p=0.002), parity >1 (OR: 1.81; 95%CI: 1.18-2.71; p=0.006), fetal abdominal circumference (FAC) measurement>360mm (OR: 34.20; 95%CI: 8.04 -145.56; p<0.001)) and<345mm (OR: 3.06; 95%CI: 1.88-5; p<0.001), presence of large for gestational age (LGA) fetus (OR: 5.09; 95%CI: 1.35-19.21; p=0.016), premature rupture of membranes (PROM) (OR: 1.52; 95%CI: 1-2.33; p=0.041), and cervical dilatation<5cm at admission (OR: 2.12; 95%CI: 1.34-3.34; p=0.001) were associated with the group requiring a C-section. Conclusion This is the first study evaluating the risk factors for C-section in low-risk multiparous women with a history of vaginal birth according to the Robson classification 3 and 4. Fetal distress and suspected fetal macrosomia constituted most of the Csection indications.

Diâmetro abdominal sagital de adolescentes obesos e sua associação com os critérios da síndrome metabólica / Sagittal abdominal diameter of obese adolescents and its association with the criteria of metabolic syndrome

INTRODUÇÃO: O diâmetro abdominal sagital (DAS) é uma medida antropométrica relacionada com a gordura visceral e utilizada para avaliar a obesidade abdominal, uma variável associada à síndrome metabólica (SM). Sua utilização é indicada na prática clínica para avaliação de risco cardiometabólico em adolescentes obesos. Este estudo consiste em verificar a correlação entre o DAS e a circunferência abdominal (CA) na avaliação da obesidade central e sua associação com os critérios da SM e Home-ostatic Model Assessment Insulin Resistance (HOMA-IR) em adolescentes obesos. MÉTODO: Estudo de corte transversal constituído por adolescentes obesos matriculados nos ambulatórios das Unidades de Endocrinologia Pediátrica e de Adolescentes do Instituto da Criança do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. As variáveis antropométricas avaliadas foram: índice de massa corporal (IMC), Escore Z do IMC, %GC, CA, DAS. As variáveis laboratoriais e clínicas foram: HDL-c, triglicérides, glicemia e insulina para o cálculo do HOMA-IR e pressão arterial sistólica e diastólica. RESULTADOS: De acordo com os critérios utilizados pelo IDF, 27,7% dos 83 adolescentes, com idade entre 14 e 18 anos apresentaram SM e o DAS demonstrou estar significantemente associado com as variáveis pressão arterial sistólica (PAS), pressão arterial diastólica (PAD) e HOMA-IR nos grupos geral, feminino e masculino. A concordância entre a CA e o DAS é significante nos grupos geral (Kappa 0,511; p<0,001), feminino e masculino com SM (Kappa 1,00; p<0,001) e o DAS oferece vantagem metodológica na sua mensuração. Conclusão: Nas condições deste estudo, conclui-se que as medidas antropométricas CA e DAS se equivalem para o grupo avaliado na classificação da SM. O DAS é preditor de PAS, PAD e de HOMA-IR e é forte indicador de risco cardiometabólico em adolescentes obesos

Perfis metabólico e nutricional como preditores da síndrome da apneia obstrutiva do sono / Metabolic and nutritional status as predictors of obstructive sleep apnea syndrome

RESUMO Objetivo: Correlacionar os perfis metabólico e nutricional com a presença e gravidade da síndrome da apneia obstrutiva do sono. Métodos: Estudo transversal com pacientes adultos e idosos, de ambos os sexos, atendidos no Laboratório do Sono e Coração do Pronto Socorro Cardiológico Universitário de Pernambuco, entre junho e setembro de 2014. Os pacientes se submeteram à polissonografia, à bioimpedância elétrica e a aferições antropométricas. Foram verificadas a presença da síndrome metabólica e outras morbidades. Resultados: A amostra total foi constituída por 50 pacientes, com idade média de 57,52±9,80 anos, sendo que 94% receberam diagnóstico de síndrome da apneia obstrutiva do sono e 74% possuíam síndrome metabólica. As seguintes médias foram obtidas: índice de massa corporal (31,54±5,82 kg/m2); circunferência do pescoço (39,14±4,33 cm); circunferência da cintura (106,72±11,22 cm); diâmetro abdominal sagital (23,00 cm [21,00-24,00]). O índice de massa corporal, a circunferência da cintura e o diâmetro abdominal sagital apresentaram valores mais elevados (p<0,05) entre os pacientes com síndrome da apneia obstrutiva do sono grave, quando comparados aqueles com a forma leve. O diâmetro abdominal sagital apresentou moderada correlação com o índice de apneia e hipopneia e a gordura corporal apresentou fraca correlação. Conclusão: A obesidade, a circunferência do pescoço, o diâmetro abdominal sagital e a síndrome metabólica tiveram associação positiva com a gravidade da síndrome da apneia obstrutiva do sono. Dentre os parâmetros antropométricos avaliados, o diâmetro abdominal sagital mostrou ser o mais adequado preditor para avaliar a presença e gravidade da síndrome da apneia obstrutiva do sono.

ABSTRACT Objective: To compare metabolic and nutritional profiles with the presence and severity of obstructive sleep apnea syndrome. Methods: This cross-sectional study included male and female adults and older adults treated at the Sleep and Heart Laboratory of Pernambuco Cardiologic Emergency Medical Services between June and September 2014. Patients underwent polysomnography, bioelectrical impedance analysis, and anthropometric measurements. Presence of the metabolic syndrome and other morbidities was investigated. Results: The sample consisted of 50 patients with a mean age of 57.52±9.80 years, of which 94% were diagnosed with obstructive sleep apnea syndrome, and 74% had the metabolic syndrome. Other mean sample characteristics were: body mass index (31.54±5.82 kg/m2); neck circumference (39.14±4.33 cm); waist circumference (106.72±22.11 cm); sagittal abdominal diameter (23.00 cm [21.00-24.00]). Patients with severe obstructive sleep apnea syndrome had higher body mass index, waist circumference, and sagittal abdominal diameter (p<0.05) than those with mild condition. Sagittal abdominal diameter was correlated moderately with the apnea-hypopnea index and mildly with body fat. Conclusion: Obesity, neck circumference, and the metabolic syndrome had a positive association with obstructive sleep apnea syndrome severity. Of the study anthropometric parameters, sagittal abdominal diameter was the most suitable predictor of presence and severity of obstructive sleep apnea syndrome.

Objetivo: Correlacionar indicadores antropométricos; índice de cintura-cadera (ICC) y diámetro sagital (DS) con IAH en candidatos a cirugía bariátrica (CB). Materiales y métodos: Se registraron el IMC, ICC y DS. Se evaluó IAH relevante (> 15 eventos/hora) mediante poligrafía respiratoria (PR) y se correlacionó con sexo, edad > de 50 años, escala de Berlín, HTA, DS ≥ 30 e ICC ≥ 1. Resultados: Fueron analizados 81 pacientes (mujeres 50/61.73%). Las medias fueron; edad: 46.32, SD: 11.53, IMC: 45.98 SD: 8.41 (rango: 35-77 kg/m²) y Epworth (ESS): 8.87, SD: 4.86. El 100% presentó alto riesgo por Berlín, ESS >10: 33.86% e HTA: 39.51%. Los indicadores poligráficos (medias) fueron; tiempo de registro: 407 minutos (SD: 110) e IAH: 20.66 (SD: 24.02). La prevalencia de IAH > 5/hora fue del 77.77%, IAH > 15/hora; 34.56% y el 21% obtuvo > 30/hora. La media del DS fue de 30.9 (SD: 4.60) y del ICC de 0.97 (SD: 0.09). Modelos de regresión para DS ≥ 30 cm (OR: 1.97 y p = 0.239) + ICC ≥ 1 (OR: 1.394 y p = 0.636) no alcanzaron significación cuando se adicionó sexo masculino (OR: 5.29 y p = 0.003). En regresión logística las variables no alcanzaron significación; DS ≥ 30 cm: OR de 1.25 (CI95%: 0.33-4.66) p = 0.739, ICC ≥ 1; OR 0.93 (SD: 0.19-4.62) p = 0.939 y muestran predictor exclusivamente al sexo masculino (OR: 4.20. CI95%: 1.21-14.5) p = 0.023. Conclusiones: La obesidad central según ICC ≥ 1 y DS ≥ 30 cm no tuvo correlación con IAH > 15/hora. Continúan siendo necesarios métodos objetivos (PR o polisomnografía) para evaluar la severidad del trastorno.

Objective: To assess correlation between anthropometric indexes; waist to hip ratio (WHI), sagital diameter (SD) and AHI obtained from home respiratory polygraphy (RP) in bariatric surgery candidates (BS). Methods: BMI, WHI and SD were recorded for BS candidates. Sleep apnea was defined as significant if AHI >15 events/hour. Variables included in the model were; sex, age greater than 50 years, Berlin questionnaire, history of hypertension (HBP), SD ≥ 30 and WHI ≥ 1. Results: Data from 81 patients were analyzed (50 women, 61.73%), age 46.32, SD 11.53, BMI 45.98 SD: 8.41 (range: 35-77 kg/m²) and ESS: 8.87 (SD: 4.86). 100% had high risk by Berlin questionnaire, 33.86% had ESS >10, and 39.51% HBP. Respiratory polygraphy data were: recording time: 407 minutes (SD: 110) and AHI: 20.66 (SD: 24.02). Prevalence of AHI > 5/hour (pathological) was 77.77%; significant AHI (> 15/hour) 34.56%, and 21% had > 30/hour. The SD was 30.9 (SD: 4.60) and WHI of 0.97 (SD: 0.09). 48.15% had a WHI ≥ 1. Logistic regression showed: DS ≥ 30 cm (OR: 1.97, p = 0.239) + WHI ≥ 1 (OR 1.394, p = 0.636) and it did not reach significance when male sex is added. Both variables included in the model did not reach statistical significance; SD ≥ 30 cm: OR of 1.25 (95% CI: 0.33-4.66) p = 0.739, ICC ≥ 1, OR 0.93 (SD: 0.19-4.62) p = 0.939. In the model, male sex was the only predictor (OR: 4.20, CI 95%: 1.21. -14.5) p = 0.023. Conclusions: Central obesity measured by WHI ≥ 1 and SD ≥ 30 cm had no significant correlation with AHI > 15/h. Objective methods (RP or polysomnography) are needed to assess the severity of the disorder before prescribing bariatric surgery.

Association between morphometric variables and nocturnal desaturation in sickle-cell anemia / Associação entre variáveis morfométricas e dessaturação noturna na anemia falciforme

OBJECTIVE: to evaluate associations between morphometric variables, cervical circumference (CC), and abdominal circumference (AC) with the presence of nocturnal desaturation in children and adolescents with sickle-cell anemia. METHODS: all patients were submitted to baseline polysomnography, oral cavity measurements (maxillary intermolar distance, mandibular intermolar distance, and overjet), and CC and AC measurements. RESULTS: a total of 85 patients were evaluated. A positive correlation was observed between the height/age Z-score and CC measurement (r = 0.233, p = 0.031). The presence of nocturnal desaturation was associated with CC (59.2± 9.3 vs. 67.5 ± 10.7, p = 0.006) and AC measurements (27.0 ± 2.0 vs. 29.0± 2.1, p = 0.028). There was a negative correlation between desaturation and maxillary intermolar distance (r = -0.365, p = 0.001) and mandibular intermolar distance (r = -0.233, p = 0.037). CONCLUSIONS: the morphometric variables of CC and AC may contribute to raise suspicion of nocturnal desaturation in children and adolescents with sickle-cell anemia. .

OBJETIVO: avaliar associações entre variáveis morfométricas e circunferências cervical (CC) e abdominal (CA) com a presença de dessaturação noturna em crianças e adolescentes com anemia falciforme. MÉTODOS: todos os pacientes foram submetidos à polissonografia basal, medidas da cavidade oral (distância intermolar da maxila, distância intermolar da mandíbula e overje), CC e CA. RESULTADOS: foram avaliados 85 pacientes. Foi observada correlação positiva entre o escore Z altura/idade e a medida da circunferência cervical (r = 0,233 p = 0,031). A presença da dessaturação noturna associou-se com as medidas da circunferência cervical (59,2 ± 9,3 vs 67,5 ± 10,7; p = 0,006) e abdominal (27,0 ± 2,0 vs 29,0 ± 2,1; p = 0,028). Houve correlação negativa entre a dessaturação e a distância entre os segundos molares da maxila (r =-0,365, p = 0,001) e da mandíbula (r = -0,233, p = 0,037). CONCLUSÕES: as variáveis morfométricas e circunferências cervical e abdominal podem contribuir para a suspeita da dessaturação noturna em crianças e adolescentes com anemia falciforme. .

The Clinical Characteristics of Colonic Pseudo-obstruction and the Factors Associated with Medical Treatment Response: A Study Based on a Multicenter Database in Korea

Colonic pseudo-obstruction (CPO) is defined as marked colonic distension in the absence of mechanical obstruction. We aimed to investigate the clinical characteristics of CPO and the factors associated with the response to medical treatment by using a multicenter database in Korea. CPO was diagnosed as colonic dilatation without mechanical obstruction by using radiologic and/or endoscopic examinations. Acute CPO occurring in the postoperative period in surgical patients or as a response to an acute illness was excluded. CPO cases were identified in 15 tertiary referral hospitals between 2000 and 2011. The patients' data were retrospectively reviewed and analyzed. In total, 104 patients (53 men; mean age at diagnosis, 47 yr) were identified. Seventy-seven of 104 patients (74%) showed a transition zone on abdominal computed tomography. Sixty of 104 patients (58%) showed poor responses to medical treatment and underwent surgery at the mean follow-up of 7.4 months (0.5-61 months). Younger age at the time of diagnosis, abdominal distension as a chief complaint, and greater cecal diameter were independently associated with the poor responses to medical treatment. These may be risk factors for a poor response to medical treatment.

Comparação entre as medidas de cirtometria tóraco-abdominal realizadas em decúbito dorsal e em ortostatismo / Comparison between the measures of thoracoabdominal cirtometry in supine and standing / Comparación entre las medidas de cirtometría tóraco-abdominal realizadas en decúbito dorsal y en ortostatismo

Com o objetivo de avaliar possíveis diferenças nos valores obtidos na realização da cirtometria tóraco-abdominal em ortostatismo comparado com os resultados aferidos em decúbito dorsal, foram avaliados 30 participantes com média de idade de 27,8±4,4 anos, por meio dos seguintes parâmetros: antropometria, prova de função pulmonar e mobilidade tóraco-abdominal pela cirtometria. O teste de Shapiro-Wilk foi utilizado para verificar a normalidade dos dados e o teste t pareado para a comparação entre as mensurações obtidas pela cirtometria tóraco-abdominal em decúbito dorsal e em ortostatismo. Não houve diferenças significativas na mobilidade axilar e xifoidea entre as medidas em decúbito dorsal e ortostatismo. A mobilidade abdominal mensurada em ortostatismo (2,54±1,39 cm) foi significativamente menor (34,35%) em comparação à mobilidade obtida em decúbito dorsal (3,71±1,78 cm; p<0,001). A cirtometria torácica pode ser realizada em ortostatismo como uma alternativa para a avaliação de pacientes que referem ortopnéia. A cirtometria abdominal também pode ser realizada nessa postura, com a ressalva de ser esperada uma redução em torno de um terço da mobilidade abdominal obtida em decúbito dorsal...

With the objective to evaluate possible differences in the values obtained in the thoracoabdominal cirtometry in orthostatism compared with the results in supine, 30 subjects with mean age 27.8±4.4 years were evaluated according to the following parameters: anthropometry, pulmonary function test and thocacoabdominal cirtometry. Shapiro-Wilk test was used to verify data normality and the t test was performed in order to compare the thoracoabdominal cirtometry measurements in supine and in orthostatism positions. There were no significant differences in axillar and xiphoid mobility between measurements obtained in supine and orthostatism. The abdominal mobility measured in orthostatism (2.54±1.39 cm) was significantly lower (34.35%) when compared to the mobility obtained in supine (3.71±1.78 cm; p<0.001). The thoracic cirtometry can be performed in orthostatism as an alternative for the evaluation of patients with orthopnea. The abdominal cirtometry can also be performed in this posture, with the expected one-third reduction in the abdominal mobility obtained in supine...

Needle Depth to Lumbar Plexus in Lumbar Plexus Block by Posterior Approach and Its Relation with Body Indices in Korean / 대한마취과학회지

BACKGROUND: Lumbar plexus block by posterior approach has been used for thigh and hip surgery and unilateral low back pain and/or low extremity pain control. We measured the needle depth from the skin to the lumbar plexus and its relation with body indices in Korean. METHODS: Forty-eight (male 35, female 13) patients with unilateral low back pain and/or low extremity pain received lumbar plexus block by the posterior approach known as "psoas compartment block". We measured the distance from the skin to the lumbar plexus with the aid of a nerve stimulator and evaluated its relation to body mass indices such as weight, height, abdominal circumference and body mass index (BMI; kg/m2). RESULTS: The distance described above was 7.42 +/- 0.82 cm (range 6.0-9.5 cm) in males and 7.18 +/- 1.24 cm (range 5.3-10.0 cm) in females. Its relation to body weight was greater than with other body indices. The Pearson's coefficient between the distance and body weight was 0.745 in males and 0.842 in females. The predicted distance (cm) was 4.23 + 0.0471 x weight (kg) in males (adjusted R2 = 0.532) and 1.25 + 0.0975 x weight in females (adjusted R2 = 0.682). CONCLUSIONS: Body weight is the most important factor for prediction of the distance from the skin to the lumbar plexus. The distance was about 6-10 cm in korean patients.

Clinical Measurement of Distance from Skin to Epidural Space in L3-4 Interspace

The purpose of this study is to measure the skin epidural distance(SED) of L3-4 interspace and to correlate SED with the individual constitutional data of patients such as body-weight, height, abdominal circumference and body mass index(BMI; kg/m2). In this study we examined 120 patients (45 men and 75 women) who had no pathological abnormality in L3-4 interspace such as herniated disc, spondylolisthesis and spinal stenosis in MRI study, although majority of patients had pathology below this level. The SED was measured under fluoroscopic guide with loss of resistance technique, and we also measured individual constitutional data of patients. Pearson's correlation analysis of the data showed that there were no correlations of statistical significance between SED and the height, abdominal circumference of the patient (p>0.01). But there were statistically significant correlations between SED and body-weight as well as BMI (p<0.0001). Linear regression analysis of these data showed significant correlations between SED and body weight(male r(2)=0.49, p<0.0001, y=0.37x18.1; female r(2)=0.31, p<0.0001, y=0.18x30.8), BMI(male r(2)=0.52, p<0.0001, y=0.89x23.1; female r(2)=0.35, p<0.0001, y=0.41x31.6).

Correlation between Obesity Indices and Cardiovascular Risk Factors and Usefullness of Abdominal Obesity Indices / 예방의학회지

It is a well known fact that obesity is an important cause of cardiovascular disease, emphasized by many studies. Recently, cardiovascular diseaase has been found to correlate not only to the extent of obesity, but also the fat distribution of the individual; especially, focusing on obesity of the abdomen. Unfortunately, the proposed indices for abdominal obesity are numerous, and the results vary according to the index chosen. Three-hundred and twelve bus drivers in November, 1995, were chosen as subjects of this study. The author chose to measure serum lipid levels, fasting blood sugar levels and blood pressure, that are thought to be important risk factors of cardiovascular diseases. Obesity indices were calculated using anthropometric measurements. We were able to evaluate the significance of obesity indices by examining correlations between these indices and the risk factors of cardiovascular disease. The results obtained were as follows: 1. The abdominal obesity indices and risk factors of cardiovascular disease, the levels of total cholesterol in the serum, fasting blood sugar levels, and diastolic blood pressure, increased significantly according to age. 2. There was a significant difference in the abdominal obesity indices according to drinking and smoking habits controlled for age. Among the risk factors of cardiovascular disease, triglyceride and diastolic pressures had significant differences according to the presence or absence of a drinking history controlled for age. 3. Although all obesity indices showed significant correlations, the weakest correlation was between BMI and abdominal diameter index and the strongest correlation was between sagittal diameter and sagittal diameter matched for height. 4. There was a negative correlation between HDL-cholesterol and obesity indices. The weakest correlation was between fasting blood sugar levels and both SD and SDH showed correlations with the risk factors. 5. There was a significant correlation between SD and total cholesterol in the serum and fasting blood sugars controlled for age, drinking, and BMI. 6. After categorizing the subjects into 2 separate age groups at the 40 year mark, in the less than 40 year old age group, controlled for drinking and BMI, the results of comparitive studies have shown correlations between total cholesterol serum levels and waist-hip ratio, conicity-index, and SD. There were correlations between fasting blood sugar levels and SD, ADI, and SDH. There were no correlations between obesity indices and both total cholesterol serum levels and fasting blood sugar levels in the greater than 40 year old age group. There were significant correlations between abdominal obesity indices and total serum cholesterol or fasting blood sugar levels in the less than 40 year old age group, but no correlations in the age group over 40. These correlated factors between abdominal obesity and cardiovascular disease are assumed to exist in Korea as well. Furthermore, in this study a high correlation was found between SD, SDH and the risk factors of cardiovascular disease. Even when controlled for age, drinking, smoking, and BMI, the correlations between risk factors of cardiovascular disease and these indices exist. Therefore, the obesity indices, SD and SDH may prove to be important prognostic indicators or risk factors of cardiovascular disease
