"The discovery that sodium transport and glucose transport are coupled in the small intestine so that glucose accelerates absorption of solute and water (is) potentially the most important medical advance this century."

ORT ... How it Works - We are often asked to explain how ORT works - a question that can only be answered successfully by first considering some of the simple physiology of the normal intestine and then the changes that occur in a state of diarrhoeal disease. This is a basic discussion of the question written in reasonable non-technical terms to provide some of this interesting background information.

Multiple-micronutrient supplementation for women during pregnancy | Cochrane

In low- and middle-income countries, many women have poor diets and are deficient in nutrients and micronutrients which are required for good health. Micronutrients are vitamins and minerals that are needed by the body in very small quantities but are important for normal functioning, growth and development. During pregnancy, these women often become more deficient, with the need to provide nutrition for the baby too, and this can impact on their health and that of their babies. Combining multiple micronutrients has been suggested as a cost-effective way to achieve multiple benefits for women during pregnancy. Micronutrient deficiencies are known to interact and a greater effect may be achieved by multiple supplementation rather than single-nutrient supplementation, although interactions may also lead to poor absorption of some of the nutrients. High doses of some nutrients may also cause harm to the mother or her baby. This systematic review included 19 trials involving 138,538 women, but only 17 trials involving 137,791 women contributed data. The included trials compared pregnant women who supplemented their diets with multiple micronutrients with pregnant women who received a placebo or supplementation with iron, with or without folic acid. Overall, pregnant women who received multiple-micronutrient supplementation had fewer low birthweight babies, small-for-gestational-age babies, and stillbirths than pregnant women who received only iron, with or without folic acid. The evidence for the main outcomes was found to be of high quality. These findings, consistently observed in several other systematic reviews of evidence, provide a strong basis to guide the replacement of iron and folic acid with multiple-micronutrient supplements for pregnant women in low- and middle-income countries countries where multiple-micronutrient deficiencies are prevalent among women.

Vitamin A supplementation during pregnancy for maternal and newborn health outcomes | Cochrane

Vitamin A is a fat-soluble vitamin found in liver, kidney, eggs, and dairy produce. Low dietary fat intake or intestinal infections may interfere with the absorption of vitamin A. Natural retinoids are required for a wide range of biological processes including vision, immune function, bone metabolism and blood production. In pregnancy, extra vitamin A may be required. Currently, the World Health Organization (WHO) and other international agencies recommend routine vitamin A supplementation during pregnancy or at any time during lactation in areas with endemic vitamin A deficiency (where night blindness occurs).

Infantile haemangioma: topical timolol | Key-points-from-the-evidence | Advice | NICE

Limited evidence from 2 small randomised controlled trials (RCTs) and several observational studies suggests that topical timolol reduces the redness of superficial haemangiomas and may reduce their size or volume, but the clinical significance of these changes is unclear. The number of adverse events seen in the studies was low. However, systemic absorption has been shown with timolol used topically to treat infantile haemangiomas and larger studies would be useful to provide more safety data.

Sirolimus Stent Differences From Elution Kinetics, Says PANDA

"The beauty of this study was that it focused on how the same drug was eluted from almost-identical stents," just with different elution and polymer-absorption rates over time, said one expert.

Switching AED Forms Improves Seizure Control for ID Patients

Seizure control improved by 50% when patients with epilepsy and intellectual disability were switched from a liquid to a granule form of levetiracetam, a study shows. Gut absorption may be the reason.

Cerebrospinal fluid

The cerebrospinal fluid (CSF) is produced from arterial blood by the choroid plexuses of the lateral and fourth ventricles by a combined process of diffusion, pinocytosis and active transfer. A small amount is also produced by ependymal cells. The choroid plexus consists of tufts of capillaries with thin fenestrated endothelial cells. These are covered by modified ependymal cells with bulbous microvilli. The total volume of CSF in the adult ranges from140 to 270 ml. The volume of the ventricles is about 25 ml. CSF is produced at a rate of 0.2 - 0.7 ml per minute or 600-700 ml per day. The circulation of CSF is aided by the pulsations of the choroid plexus and by the motion of the cilia of ependymal cells. CSF is absorbed across the arachnoid villi into the venous circulation and a significant amount probably also drains into lymphatic vessels around the cranial cavity and spinal canal. The arachnoid villi act as one-way valves between the subarachnoid space and the dural sinuses. The rate of absorption correlates with the CSF pressure. CSF acts as a cushion that protects the brain from shocks and supports the venous sinuses (primarily the superior sagittal sinus, opening when CSF pressure exceeds venous pressure). It also plays an important role in the homeostasis and metabolism of the central nervous system.
