Establishing reference intervals of serum anti-Müllerian hormone in women of childbearing age (20-34 years old) in Henan area / 中华检验医学杂志

Objective:To analyze the serum anti-Müllerian hormone (AMH) levels in women of childbearing age in different age groups in Henan, and establish the medical reference intervals based on measurement results from this population.Methods:From January to June 2017, 620 healthy women of childbearing age (20-34 years old), who underwent pre-pregnancy eugenics and pre-marital checkups in 13 project sites in Henan, were included in this study. Participants were divided into 3 age groups: 20-24 years group ( n=210), 25-29 years group ( n=207), and 30-34 years group ( n=203). Spearman correlation coefficient was used to evaluate the correlation between serum AMH level and age; Kruskal-Wallis H test was used to compare the serum AMH levels of different age groups; Wilcoxon test was used for comparison between pairs; the percentile method ( P2.5, P97.5) was used to establish medical reference interval of serum AMH in women of childbearing age for the whole population and different age groups, respectively. Results:The correlation coefficient between serum AMH and age in women of childbearing age (20-34 years old) is -0.17 ( P<0.001). There was a statistically significant difference in the overall frequency distribution of serum AMH levels among the three different age groups ( H=21.978, P<0.05). Among them, there is a statistically significant difference between the 20-24 years group and the 30-34 years group ( Z=4.292, P<0.05). There is a statistically significant difference between the 25-29 years group and the 30-34 years group ( Z=3.803, P<0.05). The reference range of serum AMH is 0.281-9.693 μg/L in this cohort; the reference range of serum AMH is 0.524-10.760, 0.229-9.200, 0.115-8.200 μg/L for women of childbearing age at 20-24, 25-29 and 30-34 years, respectively. Conclusion:The serum AMH level of women of childbearing age (20-34 years old) decreases with age. It is of great significance to establish the serum AMH reference interval for women of childbearing age in different age groups in Henan.

A qualitative research on posttraumatic growth in patients with cervical cancer who had a hysterectomy at the childbearing age / 中国实用护理杂志

Objective We aimed to explore the experience of posttraumatic growth in patients with cervical cancer who had a hysterectomy at the childbearing age.Methods The phenomenological methodology was used in the study.An in-depth interview was conducted among 12 patients chosen by purposive sampling method.Results Through careful analysis and collation,three themes were identified:smashing the original assumption,searching the meaning of existence and rebuilding the new cognitive schemata.The experience of patients' was conformed to the model which was put forward by Tedeschi,and the theme changes in personal relationships,personal strength,altruism born from sufferings and new philosophy of life were conformed to theoretical connotation of PTG.Conclusions Clinical medical staff should update psychological nursing concept timely and taking advantages of PTG to help patients pass through their difficult period.

Prevalencia de deficiencia y consumo de hierro, zinc y cobre en mujeres chilenas en edad fértil / Prevalence of deficiency and dietary intake of iron, zinc and copper in Chilean childbearing age women

El objetivo del presente estudio es evaluar el estado nutricional e ingesta de hierro (Fe), zinc (Zn) y cobre (Cu) en mujeres chilenas en edad fértil. Se estudió una muestra de conveniencia de 86 mujeres entre 18 a 48 años de edad de la ciudad de Santiago, Chile. El estado nutricional de Fe se determinó a través de hemoglobina (Hb), volumen corpuscular medio, saturación de transferrina, zinc protoporfirina, ferritina sérica (FS), Zn y Cu séricos. La ingesta dietética fue evaluada con una encuesta de frecuencia de consumo. Un 4,7% de las mujeres presentó anemia por deficiencia de Fe, 21% deficiencia de Fe sin anemia, 26% depósitos depletados de Fe y un 48,3% estado nutricional normal de Fe. Las mujeres obesas presentaron mayores niveles de FS (p<0,01) al comparar con mujeres con peso normal. Además, presentaron niveles más altos de Hb (p<0,05) al comparar con mujeres con estado nutricional normal y sobrepeso. El 3,5% y 2,3% de las mujeres presentó deficiencia de Zn y Cu, respectivamente. El 95%, 94% y 99% cumplió el EAR para Fe, Zn y Cu, respectivamente. No se encontraron diferencias significativas en la ingesta de micronutrientes entre las mujeres al comparar por estado nutricional. En conclusión, un alto porcentaje de las mujeres presentó una ingesta adecuada de micronutrientes. Además existe una baja prevalencia de deficiencia de Zn, Cu y anemia. Sin embargo, un 47% presenta deficiencia de Fe en etapas anteriores a la de anemia.

The aim of the present study was to evaluate anemia, the biochemical status and dietary adequacy of iron (Fe), zinc (Zn) and copper (Cu), in Chilean childbearing age women. We studied a convenience sample of 86 women aged 18 to 48 years from Santiago, Chile. We determined anemia and the micronutrient status through hemoglobin (Hb) mean corpuscular volume, transferrin saturation, zinc protoporphyrin, serum ferritin (SF), serum Zn and Cu. Dietary adequacy was estimated using a food frequency questionnaire. Of all women, 4.7% had Fe deficiency (ID) anemia, 21 % ID without anemia, 26 % depleted Fe stores and 48.3% normal Fe status. Obese women had higher SF (p<0.01) compared with those classified as having normal BMI. Also, showed higher Hb (p<0.05) concentrations compared with overweight and normal weight women. Participants showed 3.5 % and 2.3 % of Zn and Cu deficiency, respectively. Also, 95 %, 94 % and 99 % had adequate intake of Fe, Zn and Cu respectively, according to EAR cut points. There were no significant differences in micronutrients intake across different nutritional status. There was a low prevalence of anemia, Fe, Zn and Cu deficiency. A high percentage of women reached micronutrient adequacy. However, 47% of women had ID without anemia and Fe depleted stores.

Childbearing women of twenty and under are at greater risk than those of twenty-five and over for compromised folate status

This study assessed folate intakes, folate concentrations in plasma and erythrocytes, plasma total homocysteine (tHcy) concentration, and urinary excretion of folate metabolites in Korean women with childbearing potential. A total of 23 women voluntarily participated in this study. Precise dietary intakes for 3 consecutive days were determined by weighing all foods consumed and folate intake was calculated using a computer-aided dietary analysis system. Folate concentration of plasma and erythrocytes was determined by a microbiological method. Plasma tHcy concentration was assayed using an HPLC analysis method. Urine excreted over the same period of time was collected and folate catabolites, para-aminobenzoylglutamate (pABG) and para-acetamidobenzoylglutamate (ApABG), were evaluated using a reverse-phase HPLC method after affinity chromatography. Young women of 20 and under were likely to consume less folate with low energy intake, had lower folate concentration in plasma and erythrocytes, and excreted a lesser amount of ApABG and total folate catabolites than women of 25 years and over. The results of this study confirmed that young Korean women with childbearing potential, especially those under 21 years of age, might be at risk for compromised folate status due to insufficient folate intakes from inadequate energy consumption.
