New Guidelines For Estimating Women’s Due Dates Issued By OB-GYN Group
It failed during the Great Depression. Clason maps are notorious for having no date information. Instead, various elements of the maps changed over time. Use the link above to connect to a site at Michigan State University to learn more about dating Clason maps. Diversified Maps The following information was provided by Jim Wakefield: Some, but not all, Diversified maps contianed a three or four digit date code. It was often, but not always in the bottom left or bottom right corner of the body of the map. If the code contains three digits, the first digit appears to reference the base map. If the code contains four digits, the first two digits reference the base map.
Can doctors determine exact conception date with ultrasound?

At the first trimester scan they confirm that the fetus is alive, they assess the gestational age by measuring the crown-rump length and will also look for any major problems.
Joyful carols, special liturgies, brightly wrapped gifts, festive foods—these all characterize the feast today, at least in the northern hemisphere. But just how did the Christmas festival originate? The Bible offers few clues: Yet most scholars would urge caution about extracting such a precise but incidental detail from a narrative whose focus is theological rather than calendrical.
The extrabiblical evidence from the first and second century is equally spare: There is no mention of birth celebrations in the writings of early Christian writers such as Irenaeus c. Origen of Alexandria c. According to John, Jesus is crucified just as the Passover lambs are being sacrificed. This would have occurred on the 14th of the Hebrew month of Nisan, just before the Jewish holiday began at sundown considered the beginning of the 15th day because in the Hebrew calendar, days begin at sundown.
In Matthew, Mark and Luke, however, the Last Supper is held after sundown, on the beginning of the 15th. Jesus is crucified the next morning—still, the 15th. Its observance could even be implied in the New Testament 1 Corinthians 5:
Conversely, a good argument can be made out to estimate the delivery date by ultrasound and to use menstrual dating only to decide when to do an ultrasound examination 2. Is such accuracy necessary? In the second trimester, ultrasound estimation of the gestational age improves the accuracy of biochemical screening for spina bifida and Down’s syndrome.
On the other hand, it can be argued that ultrasound screening can replace biochemical screening of both these conditions, without prior knowledge of the exact gestational age. In the third trimester gestational age is of use to decide on expectant management or delivery in a complicated pregnancy.

By earning the Midwife Sonography Certificate, midwives gain a critical edge in promoting public safety in women’s point-of-care ultrasound. In order to earn the Midwife Sonography Certificate, the certified-midwife must pass both required components in the following order: Practical Examination You may begin acquiring this experience before passing the computer-based examination and then once that examination is passed, you may submit the practical portion. Once the eligibility requirements have been met and your application has been approved, you can take the computer-based examination.
Upon successfully completing the computer-based examination, you must successfully complete the Practical examination within two years. Midwife Sonography Computer-Based Examination The Midwife Sonography computer-based examination is two hours long and contains multiple-choice questions. As a windowed examination, scores for the Midwife Sonography computer-based examination will be available approximately 60 days following the close of the administration via MY ARDMS.
Upon successfully completing the computer-based examination, you will then be eligible to complete the Practical examination within two years from the date of receiving your computer-based results.

Having a scan in the first few months of pregnancy can be a thrilling experience. It’s amazing to see the little blob with a heartbeat that will soon become your baby. When will I have my first scan?

Click here for additional information. I want to know if I should trust the accuracy on an ultrasound to date a pregnancy. Of all of these uses, dating the pregnancy is the most common reason to use ultrasound, particularly when the expectant mother cannot remember the date of her last period as in breast-feeding or irregular cycles.
When an ultrasound is performed, measurements of the head, abdomen, thigh, and amount of amniotic fluid are done. This creates error in that the baby will compute out to be further along than he or she really is. For instance, say you normally have eight and nine pound babies.
Your First Prenatal Visit
Prior to the 18th century, caring for pregnant women in Europe was confined exclusively to women, and rigorously excluded men. The expectant mother would invite close female friends and family members to her home to keep her company. The presence of physicians and surgeons was very rare and only occurred once a serious complication had taken place and the midwife had exhausted all measures to manage the complication. Calling a surgeon was very much a last resort and having men deliver women in this era whatsoever was seen as offending female modesty.
The estimates determined by a woman’s fertility team — for example, the age of the embryo and date of transfer in the case of IVF — should be the primary measure used to determine a woman’s due date, as opposed to subsequent ultrasounds.
Stone spheres in Costa Rica Photo Credit: Known locally as Las Bolas “The Balls” , these monuments were the works of a Pre-Colombian civilization, and most are made from gabbro, a rock that forms from molten magma. The people who carved the stones into their perfectly spherical shapes likely did so using other small stones, according to archaeologists who study the ancient rocks. Many non-experts have speculated that the so-called Diquis Spheres were used for astronomical purposes, while others think they may have pointed the way to significant places.
The truth is that no one knows for sure. The Chibchan people who once populated Costa Rica and other parts of Central America vanished in the wake of the Spanish conquest, and the purpose of the spheres vanished with them, John W.

Found in the sunken wreckage of a Greek cargo ship that is at least 2, years old, the circular bronze artifact contains a maze of interlocking gears and mysterious characters etched all over its exposed faces. Originally thought to be a kind of navigational astrolabe, archaeologists continue to uncover its uses and now know that it was, at the very least, a highly intricate astronomical calendar. It is still the most sophisticated device ever found from that period, preceding the next appearance of similar devices by 1, years.

This activity contributes to a significant future focus on the trust that can be placed in elements of a distributed global research infrastructure, and the increased automation of its verification. However, it is the tip of the iceberg. The WDS Knowledge Network defines many of the components of research activity for which there is some form of trusted service or infrastructure component required: The trust that is required for research infrastructure to function properly is somewhat different to the trust that can be placed in the content that is curated by the research infrastructure—although one has to recognize that the two aspects are interrelated and, in some instances, inseparable.
Furthermore, the trust that can be placed in content should ideally also distinguish between the significance and usability of that content, and its quality. These facets are not necessarily the same, but again are conflated to some extent in discussions about fitness-for-use, quality metrics, and the like. Scholarly Publication The main aim of a scholarly publication is to assert a claim in respect of a novel finding, and to expose that claim to peer review for the purpose of correction , as required1.
One needs to distinguish the rules criteria for trust associated with the process of science and the value of the content. The latter is largely judged by significance, and measured—with varying degrees of usefulness—through citation indices and impact factors. There are arguments that this stream of self-correcting progress is broken , especially in some disciplines , and this is strongly related to the criteria for trust. Such criteria are largely stated informally and implemented with varying degrees of diligence in research institutions, and are mostly delegated to peer review to determine if the result is trustworthy.
Peer review purports to determine originality not easily automated, and essentially linked to end-user value , quality certainly possible to automate and validity can be partly automated. One could—and in my view, should—argue that processes can be verified objectively and preferably automatically, and that our aim should be to certify their veracity using measurable criteria. Such validity and quality criteria could be extended to feasibility of reproduction, access to supporting datasets, and the like.
Coding Obstetrical Ultrasounds
We validated the performance of our chart using an independent twin cohort, and showed in a further cohort of consecutive ultrasounds it would materially alter dates if it used instead of any of six preexisting charts. Hence we believe our chart may possibly be the most accurate of any published chart to date pregnancies between 6—9 weeks of gestation.
In addition, we found inaccuracies in the ability of commonly used charts to estimate gestational age among IVF singleton and twin cohorts where exact dates are known. While some showed only very slight differences in the estimation of dates compared to IVF dates e. Of further concern is the fact that there appears to be significant disagreement between existing charts where some given CRL lengths, predicted gestational age can vary by many days depending on which chart is referenced.
In order to determine precisely gestational age on the day of the ultrasound scan, we have necessarily derived our reference chart from an IVF population.
To my greatest surprise,i got pregnant the very date he told me and gave birth to twins.
View All Your due date is one of the first things calculated in your prenatal care. The due date is something that will help guide both you and your practitioner for gestational age-appropriate prenatal care , testing and ultimately your baby’s birth. It is, therefore, very important to ensure that you have the most accurate due date possible. Sometimes things happen, and you might find yourself being told that your due date is really a different date than you originally expected.
Here is what you need to ask before agreeing to a change in date: Is there some new clinical data? Is my fundus top of the uterus measuring differently than expected? If so, what else might be causing that measurement to be off? One common scenario that I hear is that a mom has been told that her due date is a certain date her whole pregnancy, but then at an ultrasound near the middle of pregnancy, she is told a different date, usually only a matter of days different. But the truth is this change, if it is less than fourteen days in either direction, is probably within the normal variation, because ultrasound at this juncture is limited in its use for dating a pregnancy.
While being due a few days earlier might seem like a sweet deal now, it may be something that worries you if your pregnancy extends towards forty-two weeks. This type of change might add extra risk to your pregnancy by facing an induction of labor that is unnecessary.
