ANAT2341 Course Background 2012
I will spend the first half going through the current course design, online support and assessment criteria. This is an opportunity to ask the course coordinator questions about the course.
The first 8 weeks of human development.

- "An international team designed and built the nanocomposite tracheal scaffold and produced a specifically designed bioreactor used to seed the scaffold with the patient´s own stem cells. The cells were grown on the scaffold inside the bioreactor for two days before transplantation to the patient. Because the cells used to regenerate the trachea were the patient's own, there has been no rejection of the transplant and the patient is not taking immunosuppressive drugs."

The information is based upon data from the publication "Australia's mothers and babies 2009" and is provided for educational purposes only. The original full publication is available online from AIHW Perinatal statistics series no. 25.
In 2009 in Australia, a total 294,540 women gave birth to 299,220 babies. There were 296,791 live births and 2,341 fetal deaths. There was a 0.8% increase in the total number of births compared with 2008, but there was a fall in the rate of females aged 15-44 years in the whole population who gave birth (from 64.4 per 1,000 in 2008 to 63.6 per 1,000 in 2009).
- 2009 - 296,791 live births and 2,341 fetal deaths
- 2008 - 294,737 live births and 2,188 fetal deaths
- 2007 - 292,027 live births and 2,177 fetal deaths
- Average maternal age in 2009 was 30.0 years compared with 29.0 years in 2000.
- Approximately 41.6% of women were having their first baby.
- Average age for first time mothers was 27.9 in 2009 which was 0.3 years younger than for 2008.
- Of all first-time mothers, 13.7% were aged 35 years or older in 2009, compared with 10.3% in 2000.
- ART was used by 3.6% of women who gave birth. (from available data on assisted reproductive technology (ART) where available)
Smoking while pregnant was reported by 14.5% of all mothers and by 37.0% of teenage mothers. In the 4 jurisdictions where data on the number of antenatal visits were available, 97.3% of women who gave birth at 32 weeks or more gestation attended at least one antenatal visit, with 91.9% attending 5 or more.
Of women who gave birth during 2008, 3.8% identified as Aboriginal or Torres Strait Islander. The average age of Indigenous mothers was 25.1 years, compared with 30.1 years for non-Indigenous mothers. Over half of the Aboriginal and Torres Strait Islander mothers reported smoking during pregnancy (50.9%), compared with 14.4% of non-Indigenous women who gave birth.
Labour and delivery
About 3.8% of women who gave birth during 2009 identified as Aboriginal or Torres Strait Islander. Indigenous mothers are younger than non-Indigenous mothers; their average age was 25.3 years, compared with 30.2 years for non-Indigenous mothers. Smoking during pregnancy was reported by half (49.6%) of Indigenous mothers. Of Indigenous mothers who gave birth at 32 weeks or more gestation, 76.8% attended 5 or more antenatal visits.
|Breech presentation (Galletti, 1770)||Birth caesarean|
In 2009, 8.2% of babies were born preterm (before 37 completed weeks of gestation) and 0.9% post-term (42 weeks gestation or more). Overall, 6.2% of liveborn babies were of low birthweight (less than 2,500 grams) and this nearly doubled (10.8%) among mothers who smoking during pregnancy. Less than 1.5% of liveborn babies had a low Apgar score (measure of the baby’s condition at birth). The perinatal death rate was 9.8 per 1,000 births in 2009, which comprised fetal and neonatal death rates of 7.8 per 1,000 births and 3.0 per 1,000 live births respectively.

Assisted Reproductive Technology
- In 2009, there were 70,541 assisted reproductive technology (ART) treatment cycles undertaken in Australian and New Zealand.
- Of these cycles, 17.2% resulted in a live delivery (the birth of at least one liveborn baby).
- In total, 13,114 liveborn babies were born following ART treatment in 2009.
- The most important trend in ART treatment has been the increase of single embryo transfer, from 48.3% in 2005 to 69.7% in 2009.
- This trend has resulted in significant reduction of multiple delivery rate from 14.1% in 2005 to 8.2% in 2009. (More? Assisted Reproductive Technology)

Australian Developmental Abnormalities
The ten most frequently reported birth defects in Victoria between 2003-2004
- Obstructive Defects of the Renal Pelvis or Obstructive Genitourinary Defects
- Ventricular Septal Defect
- Congenital Dislocated Hip
- Trisomy 21 or Down syndrome
- Cleft Palate
- Trisomy 18 or Edward Syndrome - multiple abnormalities of the heart, diaphragm, lungs, kidneys, ureters and palate 86% discontinued.
- Renal Agenesis/Dysgenesis - reduction in neonatal death and stillbirth since 1993 may be due to the more severe cases being identified in utero and being represented amongst the increased proportion of terminations (approximately 31%).
- Cleft Lip and Palate - occur with another defect in 33.7% of cases.
Teratology is the study of abnormalities of development. Some examples of historic teratology studies.
