what are the strategic agendas?

A

strategic priority
1: save lives
2: promote well-being
3: protect health
4: optimize the health architecture
5. use platforms for health

24
Q

what are the major complications that account for nearly 75% of all maternal deaths?

A
  1. severely bleeding
  2. infection
  3. pre eclampsia and eclampsia
  4. complications from delivery
  5. unsafe abortion
  6. malaria
  7. cardiac diseases
  8. diabetes
25
main factors that prevent women from receiving or seeking care during pregnancy and childbirth are:
1.poverty 2. distance to facilities 3. inadequate and poor quality services 4.cultural beliefs and practices
26
factors of genetic disorder
1. genetic homogeneity 2. recessive inheritance
27
one that express its trait even if only one copy of the allele present
Dominant genes- A
28
only expresses its trait if two copies of the recessive allele are inherited. one from each parent
Recessive genes- aa
29
disorder of muscle weakness
fascioscapulohumeral muscular dystrophy
30
disorder which bones are exceedingly brittle
osteogenesis imperfecta
31
a disorder of connective tissue that result in an individual being thinner and taller than usual and perhaps with associated heart aortic defects.
marfan syndrome
32
child has 13 extra chromosome and severely cognitively challenged. most of these children do not survive beyond early childhood
TRISOMY 13 47XY13+/ 47XX13+ or PATAU SYNDROME
33
trisomy 13 (patau syndrome) presnt disorders are
1. cleft lip and palate 2. microcephaly 3.micropthalmos 4. low set ears 5.extra finger and toes
34
have 3 copies of chromosome 18. most these children children do not survive beyond infancy
trisomy 18 47XY18+ or 47XX18+ edwards syndrome
35
trisomy 18 47XY18+ or 47XX18+ edwards syndrome characteristics
1. severely cognitively challenge 2.sga 3. low set ears 4. small jaw 5.congenital defects 6.misshapen finger and toes 7.rocker bottom feet
36
has only one functional X chromosomes
turner syndrome 45X0 gonadal dysgenesis
37
turner syndrome 45X0 gonadal dysgenesis characteristics
1. short in stature 2. have small and nonfunctional ovaries 3.exception of pubic hair 4. neck is short webbed 5. low set of ears
38
turner syndrome 45X0 gonadal dysgenesis can be identified on sonogram during pregnancy thru?
nuchal translucency scan
39
most common cause of cognitive challenge in males. one long arm of X chromosomes is defective
fragile syndrome (46XY23Q-)
40
fragile syndrome (46XY23Q-) demonstrate maladaptive behaviors such as
hyperactivity aggresion autism reduced intellectual functioning marked deficits in speech and arithmetic
41
fragile syndrome (46XY23Q-) physical findings
1. large head 2.long face with high forehead 3. prominent lower jaw 4. large protruding ears 5.obesity 6.hyperextensive joints 7,. cardiac disorder 8. enlarged testicles
42
most frequently occurring chromosomal disorder about 1 in 800 pregnancy higher chance in 35 yrs old 1in 100 live births
