I bought these and they taste great. A Mexican buddy of mine at school let me have one and I was hooked. The only problem I had with these is that is was the Aldama brand and not Las Sevillanas but it is still a great tasting Oblea with cajeta and I plan to buy again.
The hook effect and false BFNs. Summarised, the hook effect is when someone continuously gets negative urine and blood tests but are actually pregnant. It happens because hcg levels are too high to register and is common with mothers carrying multiples or on older woman.
Hookworm, Ascaris, and whipworm are known as soil-transmitted helminths (parasitic worms). Together, they account for a major burden of disease worldwide. Hookworms live in the small intestine. Hookworm eggs are passed in the feces of an infected person. If the infected person defecates outside (near bushes, in a garden, or field) of if the feces of an infected person are used as fertilizer, eggs are deposited on soil. They can then mature and hatch, releasing larvae (immature worms). The larvae mature into a form that can penetrate the skin of humans. Hookworm infection is mainly acquired by walking barefoot on contaminated soil. One kind of hookworm can also be transmitted through the ingestion of larvae. Most people infected with hookworms have no symptoms. Some have gastrointestinal symptoms, especially persons who are infected for the first time. The most serious effects of hookworm infection are blood loss leading to anemia, in addition to protein loss.
