Cancer cells secrete VEGF to obtain nutrients to grow. Cancer cells require adequate oxygen and nutrient supply to support their growth and division, and they achieve this by inducing angiogenesis, which is the formation of new blood vessels.
Vascular endothelial growth factor (VEGF) is a growth factor that plays a significant role in angiogenesis. Cancer cells produce and secrete large quantities of VEGF, which induces the growth of new blood vessels from pre-existing ones. These blood vessels allow cancer cells to obtain nutrients and oxygen required to fuel their growth.
The newly-formed blood vessels are often highly irregular and dysfunctional and are susceptible to leaking, leading to the formation of the characteristic vascular structure of cancerous tumors. Additionally, the tumor cells use aerobic glycolysis, which enables them to obtain energy from the breakdown of glucose without the need for oxygen. This adaptation is known as the Warburg effect and is a common hallmark of many types of cancer.
In summary, cancer cells secrete VEGF to induce the formation of new blood vessels and obtain nutrients and oxygen required for their growth and division.

The syndrome is known as Holt-Oram syndrome.
Holt-Oram syndrome is a rare genetic disorder that is characterized by the presence of absent or underdeveloped thumbs and radial dysplasia, which is a malformation of the radius bone in the forearm. Additionally, individuals with Holt-Oram syndrome may also have atrial septal defects (ASD), which is a type of congenital heart defect where there is a hole in the wall that separates the two upper chambers of the heart.
Holt-Oram syndrome is inherited in an autosomal dominant pattern, which means that a person only needs to inherit one copy of the mutated gene from one parent in order to develop the syndrome. The severity of the symptoms can vary greatly among affected individuals, even within the same family. Treatment for Holt-Oram syndrome typically involves surgical intervention to correct any limb abnormalities or heart defects. Additionally, individuals may benefit from occupational or physical therapy to improve their ability to use their hands and arms.

Alpha-Med Hospital Group operates three hospitals in the RDU area: one each in Durham, Chapel Hill, and in Raleigh, respectively. One of Alpha-Med’s staple medical- surgical safety kits, PPE-Sure, is sourced from a distributor in Virginia with an order lead-time of 2 weeks and is delivered directly to each hospital’s inventory stores. Alpha- Med’s had previously aimed for reduced logistics cost footprint and hence the distributor delivered PPE-Sure directly to each hospital at no additional cost, but with the condition that the PPE-Sure kits will only be delivered in pallets of 400 kits.
Weekly demand (assume 52 weeks to a year) for PPE-Sure at each of the hospitals is independent but identically distributed with a mean of 150 kits and a standard deviation of 35 kits per hospital. Each hospital holds inventory of PPE-Sure to maintain 95% local service level.
The annual cost of holding inventory for PPE-Sure is 25% of the product cost, which is $200 per kit. There is no fixed cost to Alpha-Med associated with placing orders for PPE- Sure.
a) (10 points) What is the average inventory that should be held for PPE-Sure at each hospital in order to meet its own 95% service level requirement?
Average inventory held by each hospital: ____________________ kits
Average inventory for the region (held across the three hospitals): ______________ kits
b) (5 points) What is the total annual inventory holding cost for the RDU region for PPE-Sure under the direct-to-hospital delivery scheme as described above? Show the steps in your calculations.
Total annual inventory holding cost for the region (all hospitals): $_________________
Alpha-Med’s newly hired procurement officer has introduced a new regional and rapid depot concept by converting the Chapel Hill hospital storeroom to a regional depot for certain high demand items.
Under this system, Alpha-Med will maintain inventory for PPE-Sure kits only at one location in the region -- the Chapel Hill regional depot -- and will supply the daily demand for each hospital (including Chapel Hill) from this depot through daily van deliveries.
This would increase the cost of shipment from Chapel Hill depot to Raleigh and to Durham hospitals, respectively, by $1 per kit delivered (we can ignore the fixed cost of deliveries and the cost of supplying the Chapel Hill hospital).
The depot would maintain the same 95% service level to each hospital, as before. Orders to the distributor would now be placed only from the Chapel Hill depot.
These orders will continue to be delivered from the distributor to this Chapel Hill depot in a pallet of 400 PPE-Sure units. The distributor would still absorb the shipment cost to the Chapel-Hill depot, and the pricing would remain unchanged.
c) (10 points) What would be the safety stock for PPE-Sure at the new Chapel Hill depot serving the three hospitals from its central location?
Safety Stock for the new CH-Depot: ____________________ kits
d) (10 points) What would be the total cost to Alpha-Med of maintaining this new centralized CH-depot system for PPE-Sure, excluding the product cost itself (inventory holding cost and cost to transport from CH warehouse to Raleigh and Durham hospitals)?
Total Cost of centralized CH-depot inventory system: ____________________ $’s / year
a) Average inventory that should be held for PPE-Sure at each hospital in order to meet its own 95% service level requirement is shown below:
Average Inventory = Safety stock + (Lead time demand) /2Safety stock = Z × σ ×√(Lead time) = 1.64×35×√2= 83.68Lead time demand = 2 × Weekly demand = 2 × 150 = 300Average Inventory = 83.68 + (300/2) = 233.68 ≈ 234 kitsAverage inventory held by each hospital = 234 kitsAverage inventory for the region (held across the three hospitals) = 234 × 3 = 702 kitsb) Total annual inventory holding cost for the RDU region for PPE-Sure under the direct-to-hospital delivery scheme as described above is calculated below:
Total Cost = Average inventory × Cost per unit × Inventory carrying cost percentageTotal Cost = 702 × 200 × 25% = $35,100c) Safety stock for PPE-Sure at the new Chapel Hill depot serving the three hospitals from its central location can be calculated as follows:
Safety Stock = Z × σ ×√(Lead time) = 1.64×35×√2 = 83.68 kitsThe safety stock for the new Chapel Hill Depot serving the three hospitals from its central location is 83.68 kits.d) The total cost to Alpha-Med of maintaining this new centralized CH-depot system for PPE-Sure, excluding the product cost itself (inventory holding cost and cost to transport from CH warehouse to Raleigh and Durham hospitals) can be calculated as follows:
Total Cost = Safety Stock × Cost per unit + Delivery cost per unit × (Lead time demand)Total Cost = (83.68 × 200) + (1 × 300) = $20,736Therefore, the total cost to Alpha-Med of maintaining this new centralized CH-depot system for PPE-Sure, excluding the product cost itself is $20,736 per year.About HospitalHospital is a health service institution that organizes full health services that provide inpatient, outpatient and emergency services whose services are provided by doctors, nurses and other health professionals.

The choice of an appropriate infusion site is crucial to ensure safe and effective administration of intravenous medications or fluids. The nursing instructor should intervene if a student selects an inappropriate site, such as a site with phlebitis, infiltration, or existing complications like edema or infection.
Administering IV therapy requires knowledge of anatomy, physiology, and best practices to prevent complications. Students need to understand the principles of aseptic technique, proper site selection, and assessment of the patient's condition to make informed decisions. Choosing an incorrect infusion site can lead to adverse effects such as infiltration, extravasation, thrombosis, infection, or inadequate absorption of medications.
The nursing instructor should step in immediately to correct the student's action by providing guidance on proper site selection, emphasizing the importance of patient assessment, and reinforcing the importance of following evidence-based guidelines.
By intervening promptly, the instructor can prevent harm to the patient and ensure that students develop the necessary skills and knowledge to provide safe and effective IV therapy care.

what makes a secondary immune response faster than a primary immune response?
A secondary immune response is faster and more efficient than a primary immune response due to the immunological memory established by the nervous system. Here are the key factors that contribute to the increased speed of the secondary immune response:
Memory B cells: During the initial immune response, B cells (a type of white blood cell) undergo activation and differentiation into plasma cells that produce antibodies. However, some activated B cells differentiate into long-lived memory B cells. These memory B cells remain in the body after the primary response subsides. In a secondary immune response, when the same pathogen is encountered again, memory B cells rapidly recognize and bind to the specific antigens on the pathogen's surface. This recognition triggers faster and more robust antibody production than the primary response, leading to quicker pathogen elimination.
Memory T cells: Similarly to memory B cells, memory T cells are generated during the primary immune response. They are a subset of T cells that encounter and respond to specific antigens. Memory T cells are stored in the lymphoid organs, ready to respond quickly upon re-exposure to the same antigen. When a secondary immune response occurs, memory T cells quickly recognize the antigen presented by infected cells and initiate a targeted immune response. This recognition and response process is faster and more efficient than the initial activation of naïve T cells during the primary response.
Affinity maturation: Another advantage of the secondary immune response is affinity maturation. During the primary response, B cells produce antibodies with relatively low affinity for the antigen. However, during the secondary reaction, memory B cells undergo further mutation and selection processes, producing antibodies with higher affinity for the specific antigen. This affinity maturation allows the antibodies to bind more tightly to the pathogen, enhancing their effectiveness in neutralizing the invader.
Increased antibody production: In a secondary immune response, antibodies are produced faster and more abundantly than in the primary response. This increased antibody production is due to memory B cells. These cells can quickly differentiate into antibody-secreting plasma cells upon re-exposure to the pathogen. Rapid antibody production aids in the efficient neutralization and elimination of the pathogen before it causes significant harm.
Overall, the primary immune response serves as the initial encounter with a pathogen. The secondary immune response benefits from immunological memory, allowing for a faster, more targeted, and more potent immune response.
