Possible Predictive Factors for Low Back and Pelvic Pain at Three Months Postpartum Assessed in a Prospective Study from Early Pregnancy until the Postpartum Period

Many studies have shown that pregnancy-related low back and pelvic pain (LBPP) occurs from the second or third trimester to postpartum. LBPP is an important issue that affects pregnant women for a long period and continuation of LBPP has effects on infant rearing and return to work. Reduction of the severity of LBPP may improve the quality of daily life during pregnancy and postpartum.  

In this paper, the authors examined the intensity of LBPP, difficulty for daily life activity and mental health and their associations from early pregnancy until 3 months postpartum in a prospective study and also examined predictive factors for LBPP at 3 months postpartum. The study was conducted from March 2015 to August 2017 in a birth center in Kagawa Prefecture in Japan. The researchers recruited 55 pregnant women who responded to questionnaires in the first, second and third trimesters and at one week, one month and 3 months postpartum. They designed a self-administered questionnaire including a visual analog scale (VAS), pregnancy mobility index (PMI) of LBPP and Edinburgh postnatal depression scale (EPDS). 

The results revealed that there were significant differences in the proportions of women with LBPP in the first trimester (63.6%), second trimester (78.2%) and third trimester (83.6%) and at one week postpartum (80.0%), one month postpartum (69.1%) and 3 months postpartum (56.4%). VAS score at 3 months postpartum was significantly correlated with VAS scores at the first trimester (r = 0.410, p = 0.002), second trimester (r = 0.298, p = 0.027) and one month postpartum (r = 0.476, p < 0.001). VAS score at 3 months postpartum was significantly correlated with PMI scores at the first trimester and one month postpartum. The presence of LBPP at 3 months postpartum was significantly associated with the proportion of women with LBPP at the first trimester. In multiparous women, predictive factor of LBPP at 3 months postpartum was a past history of LBPP in the previous pregnancy.

In conclusion, the proportion of women with LBPP and the intensity of LBPP were increased at late pregnancy and gradually decreased until 3 months postpartum. LBPP at 3 months postpartum was associated with LBPP at the first trimester and a past history of LBPP in a previous pregnancy was an important factor for prediction of LBPP at 3 months postpartum. Provision of information regarding LBPP and confirmation of LBPP before pregnancy in addition to assessment of LBPP at early pregnancy are necessary for reduction of LBPP at 3 months postpartum.

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...

The Influence of Heated Soil in Crop of “Tamaris” Tomato Plants on the Biological Activity of the Rhizosphere Soil

Tomato is a plant with high heat requirements and sensitive to cold weather and frost. The optimum temperature for the growth of tomato plants is between 21˚C and 27˚C during the day and between 17˚C and 21˚C at night. The soil temperature is also very important for plant growth. The optimum soil temperature for tomato cultivation should be within the range 15˚C - 18˚C. Besides, the proper development of the root system depends on the optimal temperature of the soil. A temperature below 14˚C reduces and inhibits the growth of the root system and encourages the development of fungal and bacterial diseases. In this study, the authors aimed to evaluate the effect of heated soil on the population of bacteria, fungi and nematodes inhabiting the soil of tomato cultivar “Tamaris” growing in peat and coconut substrates. The experiment was carried out in 12 treatments and in 3 replications (one slab was one replication). The soils were tested in two different types of containers: cylinders...

Effect of Proline Pretreatment on Grapevine Shoot-Tip Response to a Droplet-Vitrification Protocol

Proline is an α-amino acid that is used in the biosynthesis of proteins. Some studies have shown that proline has been accumulated in plants in response to biotic and abiotic stresses. Exogenous proline has thus been used for improving some plant cryopreservation protocols. Further enhancement of cryopreservation efficiency for  in vitro  grapevines could be expected if stresses linked to cryopreservation procedures could be reduced. In this study, the authors studied the possible beneficial effect of proline in grapevine cryopreservation. Single-node explants from  in vitro  grown grapevine plantlets ( Vitis vinifera  L. cv Portan) were cultured on shooting media (half-strength MS + 1 μM BAP) containing no proline (control) or 50, 500, or 2000 μM filter-sterilized L-proline. Shoot tips excised from these microshoots were subjected to a PVS2-based droplet-vitrification procedure. Control and rewarmed explants were grown on a recovery medium containing ...
