When is the K factor required?
In all cases the K-factor requirement is calculated on the first business day of each month, and, as you can see, data collection for all K-factors is daily, except for K-AUM which is monthly.
What is the K factor?
K-factors will be used by Class 2 firms to determine their capital requirements. A firm’s capital requirement is the higher of its permanent minimum capital, its fixed overhead requirement, or its K-factor requirement. The K-factor requirement is the sum of: Risk-to-Client (RtC), Risk-to-Market (RtM), and Risk-to-Firm (RtF).
What is K-CMG in investment?
Clearing margin given (K-CMG) relates to a MiFID investment firm’s derivatives positions that are subject to clearing. At a high level, it allows a firm to use the amount of margin required by its clearing member. This could then be used as a basis for calculating its risk position in its derivative positions as an alternative to K-NPR. To use K-CMG, the investment firm will require regulatory approval. IFR Article 23 describes five conditions that would need to be met for approval, and the firm also would need to prove to its supervisor that it is not using K-CMG simply to arbitrage capital requirement rules.
What is K AUM?
Client assets under management and ongoing advice (K-AUM). This captures the risk of harm to clients from the poor management or execution of client portfolios. By defining a need to hold capital against this risk, it provides support and client benefits in terms of the continuity of service.
How to calculate exposure value?
2 The exposure value to any individual client or group of connected clients is calculated by adding together the positive excess a firm's long positions over its short positions in the trading book issued by the client calculated under the K-NPR rules with the exposure value of derivative contracts and SFTs to which K-TCD applies
Can K-CMG be used as an input to concentration risk?
Finally, it’s important to note that K-CMG cannot be used as an input to the concentration risk K-factor requirement – only K-NPR can be.

As already stated, firms must monitor concentration risk daily and notify their supervisor immediately of the amount of any excess and the name of the individual client or group of connected clients. That means firms will need a robust framework for measuring exposure value (EV) daily.
What does K stand for in blood?
K stands for the dialyzer clearance, the rate at which blood passes through the dialyzer, expressed in milliliters per minute (mL/min)
What is the Kt/V of dialysis?
On average, a Kt/V of 1.2 is roughly equivalent to a URR of about 63 percent. Thus, another standard of adequate dialysis is a minimum Kt/V of 1.2. The Kidney Disease Outcomes Quality Initiative (KDOQI) group has adopted the Kt/V of 1.2 as the standard for dialysis adequacy. 1 Like the URR, the Kt/V may vary considerably from treatment to treatment because of measurement error and other factors. So while a single low value is not always of concern, the average Kt/V should be at least 1.2. In some patients with large fluid losses during dialysis, the Kt/V can be greater than 1.2 with a URR slightly below 65 percent—in the range of 58 to 65 percent. In such cases, the KDOQI guidelines consider the Kt/V to be the primary measure of adequacy.
How often should you test for urea in a patient on dialysis?
To see whether dialysis is removing enough urea, the dialysis clinic should periodically—normally once a month— test a patient's blood to measure dialysis adequacy. Blood is sampled at the start of dialysis and at the end. The levels of urea in the two blood samples are then compared.
What is the amount of urea removed after predialysis?
Example: If the initial, or predialysis, urea level was 50 milligrams per deciliter (mg/dL) and the postdialysis urea level was 15 mg/dL, the amount of urea removed was 35 mg/dL.
What is the minimum URR for dialysis?
As a result, some experts recommend a minimum URR of 65 percent.
Why is Kt/V low?
If during any given month a patient's Kt/V is extremely low, the measurement should be repeated, unless a reason for the low Kt/V is obvious. Obvious reasons include treatment interruption, problems with blood or solution flow, and a problem in sampling either the pre- or postdialysis blood.
Does dialysis increase Kt/V?
The fact that a patient who loses more weight during dialysis will have a higher Kt/V does not mean it is better to gain more water weight between dialysis sessions so more fluid has to be removed, because the extra fluid puts a strain on the heart and circulation. However, patients who lose more weight during dialysis will have a higher Kt/V for the same level of URR.
Why is initial treatment important?
First, initial treatment provides the best opportunity to succeed - there is less tumor burden, and your health and the disease have not been affected adversely by prior treatments . For example, cancer cells can adapt from multiple exposures to single agent treatments, which can lead to more resistant disease later on.
What is the intent of therapy for indolent lymphoma?
Curative intent: to achieve a possible cure where the disease might be eradicated and never returns. This is a common intent of therapy for aggressive lymphoma and Hodgkin disease.
What is the most appropriate goal of lymphoma therapy?
For example, for aggressive lymphomas the most appropriate goal of therapy is usually to cure . For lymphomas with a variable clinical course a period of observation might be needed to judge its behavior.
How to treat lymphoma?
We suggest that you avoid the following : 1 Start a treatment without first consulting at least one lymphoma expert - unless symptoms or clear dangers indicate a strong need to treat, and you are comfortable with the rationale. 2 Base your treatment decision on the outcomes of other patients. Keep in mind that each lymphoma and patient can be unique. 3 Believe conspiracy theories used to promote unorthodox therapies. Consider that these theories require the complicity of multiple scientists, doctors, and regulators - who also get cancer and whose loved ones, spouses, parents, grandparents and children also get cancer.
Should we treat sa fety earlier?
Increasingly, we may consider treating earlier (before the current need to treat) with agents that have better sa fety profiles and that may be less likely to preclude benefiting from standard approaches when treatment is needed.
Can indolent lymphoma be treated with radiotherapy?
Yes. Stage I and II (localized) indolent lymphoma are typically treated at diagnosis with curative intent with localized radiotherapy. The cure rate is about 50% according to some reports.
How does vitamin K work?
Within the cell, vitamin K participates in a cyclic process . The vitamin undergoes electron reduction to a reduced form called vitamin K hydroquinone, catalyzed by the enzyme vitamin K epoxide reductase (VKOR). Another enzyme then oxidizes vitamin K hydroquinone to allow carboxylation of Glu to Gla; this enzyme is called gamma-glutamyl carboxylase or the vitamin K–dependent carboxylase. The carboxylation reaction only proceeds if the carboxylase enzyme is able to oxidize vitamin K hydroquinone to vitamin K epoxide at the same time. The carboxylation and epoxidation reactions are said to be coupled. Vitamin K epoxide is then restored to vitamin K by VKOR. The reduction and subsequent reoxidation of vitamin K coupled with carboxylation of Glu is called the vitamin K cycle. Humans are rarely deficient in vitamin K because, in part, vitamin K 2 is continuously recycled in cells.
How does vitamin K affect newborns?
Vitamin K is given as an injection to newborns to prevent vitamin K deficiency bleeding. The blood clotting factors of newborn babies are roughly 30–60% that of adult values; this appears to be a consequence of poor transfer of the vitamin across the placenta, and thus low fetal plasma vitamin K. Occurrence of vitamin K deficiency bleeding in the first week of the infant's life is estimated at 0.25–1.7%, with a prevalence of 2–10 cases per 100,000 births. Human milk contains 0.85–9.2 μg/L (median 2.5 μg/L) of vitamin K 1, while infant formula is formulated in range of 24–175 μg/L. Late onset bleeding, with onset 2 to 12 weeks after birth, can be a consequence of exclusive breastfeeding, especially if there was no preventive treatment. Late onset prevalence reported at 35 cases per 100,000 live births in infants who had not received prophylaxis at or shortly after birth. Vitamin K deficiency bleeding occurs more frequently in the Asian population compared to the Caucasian population.
What is the family of vitamin K?
Chemically, the vitamin K family comprises 2- methyl - 1,4-naphthoquinone (3-) derivatives. Vitamin K includes two natural vitamers: vitamin K 1 ( phylloquinone) and vitamin K 2 ( menaquinone ). Vitamin K 2, in turn, consists of a number of related chemical subtypes, with differing lengths of carbon side chains made of isoprenoid groups of atoms. The two most studied ones are menaquinone-4 (MK-4) and menaquinone-7 (MK-7).
What is the function of vitamin K in animals?
It is active as a vitamin in animals and performs the classic functions of vitamin K, including its activity in the production of blood-clotting proteins. Animals may also convert it to vitamin K 2, variant MK-4. Bacteria in the gut flora can also convert K 1 into MK-4.
How much vitamin K is in milk?
Human milk contains 0.85–9.2 μg/L (median 2.5 μg/L) of vitamin K 1, while infant formula is formulated in range of 24–175 μg/L. Late onset bleeding, with onset 2 to 12 weeks after birth, can be a consequence of exclusive breastfeeding, especially if there was no preventive treatment.
What happens if you don't take vitamin K?
Without vitamin K, blood coagulation is seriously impaired, and uncontrolled bleeding occurs. Research suggests that deficiency of vitamin K may also weaken bones, potentially contributing to osteoporosis, and may promote calcification of arteries and other soft tissues.
Which bacteria can synthesize vitamin K?
Function in bacteria. Many bacteria, including Escherichia coli found in the large intestine, can synthesize vitamin K 2 (MK-7 up to MK-11), but not vitamin K 1. Green algae and some species of cyanobacteria (sometimes referred to as blue-green algae) are able to synthesize vitamin K 1.
