Dialysis is a process that removes waste and excess water from the blood when the kidneys fail. It uses diffusion and osmosis across a semi-permeable membrane as an artificial replacement for kidney function. There are two main types: hemodialysis which cleanses the blood directly by passing it through a dialyzer, and peritoneal dialysis which uses the peritoneal membrane in the abdomen as a filter. Both aim to maintain fluid, electrolyte and acid-base balance by removing toxins when the kidneys are unable to do so.
Dialysis is a treatment for people whose kidneys are failing. When you have kidney failure, your kidneys don't filter blood the way they should. As a result, wastes and toxins build up in your bloodstream. Dialysis does the work of your kidneys, removing waste products and excess fluid from the blood
In medicine, dialysis is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer perform these functions naturally. This is referred to as renal replacement therapy.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
3. Dialysis (from Greek dialusis,
meaning dissolution, dia, meaning through, and
lysis, meaning loosening or splitting) is a process for
removing waste and excess water from the blood,
and is used primarily as
an artificial replacement for lost kidney function in people
with renal failure.
4. CONT….
Dialysis may be used for those with an acute disturbance
in kidney function (acute kidney injury, previously acute
renal failure), or progressive but chronically worsening
kidney function–a state known as chronic kidney disease
stage 5 (previously chronic renal failure or end-stage renal
disease).
5. Dialysis is an artificial process used to remove water
and waste substances from the blood when the
kidneys fail to function properly.
It generally works through osmosis and filtration of
fluid across a semipermeable membrane with the use
of a dialysate.
Dialysis is the procedure used to correct fluid and
electrolyte imbalances and to remove waste
products in renal failure.
6. PURPOSE
The purpose of dialysis is to maintain fluid electrolyte and acid base balance and
to remove endogenous and exogenous toxins
7. A semipermeable membrane
is a thin layer of material that
contains holes of various
sizes, or pores.
This replicates the filtering
process that takes place in the
kidneys, when the blood
enters the
larger
kidneys and the
substances are
separated from the smaller
ones in the glomerulus.
8. is used to remove fluid and uremic waste
products from the body when the kidneys cannot
do so.
It may also be used to treat patients with edema
that does not respond to treatment, hepatic coma,
hyperkalemia, hypercalcemia, hypertension,
and uremia.
9. Indications for Dialysis
• The need for dialysis may be acute or chronic.
1. Acute dialysis is indicated
A.when there is a high and rising level of serum potassium, fluid
overload, or impending pulmonary edema, increasing acidosis,
pericarditis, and severe confusion.
B.to remove certain medications or other toxins (poisoning or
medication overdose) from the blood.
2. Chronic or maintenance dialysis is indicated inchronic
renal failure, known as end-stage renal disease (ESRD
12. KIDNEYS
The kidneys are a pair of organs, each about the
size of a fist, located on either side of your spine.
13. LOCATION
Located at the Near of the abdominal cavity
in the retroperitoneal space.
14. * Urine formation
Excretion of waste products
Regulation of electrolytes
Regulation of acid base balance
Control of blood pressure
Secretion of prostaglandins
Synthesis of vitamin D to active form
KIDNEY FUNCTIONS
15. PRINCIPLE OFDIALYSIS
Dialysis works on the principles of the diffusion of solutes
and ultrafiltration of fluid across a semi-permeable
membrane.
Diffusion describes a property of substances in water.
. Substances in water tend to move
. From an area of high concentration
. Toan area of low concentration.
. Blood flows by one side of a semipermeable membrane
. A dialysate (or special dialysis fluid) flows by the opposite
side.
Diffusion
Osmosis
Ultra filtration & solvent drag
17. . Water moves from an
area of high pressure
to an area of lower
pressure
OooOOO
. More efficient in fluid
removal than osmosis
Molecules which are
dissolved in the
solvent also get
removed- solvent drag
Ultra filtration & Solvent drag
20. It is the removal of solutes and water
from body across a semipermeable
membrane (dialyzer .
21. HEMODIALYSIS
It is the procedure of cleansing the blood of
accumulated waste products. It is used for patient
with end stage renal failure or for acutely ill
patient who require short term.
22.
23. Cleanses the blood of accumulated waste
products
Removes the by-products of protein
metabolism such as urea, creatinine, and
uric acid.
Removes excessive fluids
Maintains or restores the buffer system of
the body
Maintains or restores electrolyte levels
FUNCTIONS OF HEMODIALYSIS:
25. Other chronic disease
. No vascular access
. Hemorrhage
. hypertension
. Very old people
. Inability to cope with treatment
regimen
. Coagulopathy
. Inability to survive procedure
CONTRAINDICATIONS
27. Dialyzer(Artificial Kidney)
" Plastic chamber - contains bundles
of capillary
tube through which blood circulates
while
dialysis solution travels outside the
bundle in
opposite counter current direction.
Diffusion & ultrafiltration happens
here.
28. Membranes using in dialyser
Cellulose
-Substituted Cellulose-
cellulose acetate
-Cellulosenthetic-Cellosyn/
Hemophan
-Synthetics-polyacrylonitrile,
polysulfone, polymethyl methacrylate
29. Blood Delivery system
Blood Pump - moves blood from access
site through the dialyzer &
back to the patient
Blood flow Rate - 250-500 ml/min
30. METHODS OF CIRCULATORYACCESS
Arteriovenous fistula- An arteriovenous
fistula is an abnormal connection or
passageway between an artery and a vein.
31. Usually radial artery and cephalic vein are anastomosed in nondominant arm.
Vessels in the upper arm may also be used.
After the procedure the superficial venous system of the arm dilates.
By means of two large bore needles inserted into the dialated venous system,
blood may be obtained and passess through the dialyzer.
The arterial end is used for the arterial flow and the distal end is used forthe
reinfusion of dialysed blood.
Healing of AVF requires at least 6 to 8 weeks; a central vein catheter isused.
32. ARTERIOVENOUS GRAFT-
If a patient is not a good candidate for an
arteriovenous fistula, an arteriovenous graft
is considered.
33. CENTRAL VEIN CATHETER-
• A third type of vascular access is a venous
catheter. A venous catheter is a plastic tube
which is inserted into a large vein, usually in the
neck.
34. REQUIREMENT FOR HEMODIALYSIS….
Access to patients circulation .
dialyzer with
Dialysis machine and
semipermeable membrane.
Appropriate dialysis bath.
Time- approximately 4 hrs, three times
weekly.
Place- dialysis centre or home (if feasible
38. PROCEDURE
Patient access is prepared and cannulated
Heparin is administered
Heparin and red blood flows through
semipermeable dialysis in one direction and
dialysis solution surrounds the membrane and
flows in the opposite direction.
Dialysis solution consist of highly purified water
to which sodium, potassium , calcium,
magnesium chloride, and dextrose have been
added, bicarbonate is added to achieve the the
proper pH balance.
39. Through the process of diffusion solute
in the form of electrolytes, metabolic
waste products acid base balance
components can be removed or added
to the blood.
Excess water is removed from the
blood (ultrafiltration).
The blood is then returned to the
body through patient access.
43. PERITONEUM-
forms the lining of
The peritoneum is
the serous membrane that

abdominalcavity .
It covers most of the intra-
abdominal (or coelomic)
organs, and is composed of a
layer
supported
of mesothelium
by a thin layer
of connective tissue.
44. CONTI

46. Peritoneal dialysis:
Introduction
Peritoneal dialysis(PD) is a treatment for
patients with severe chronic kidney disease.
A dialysis technique that uses the patient's own body
tissue-peritoneal membrane inside the abdominal
cavity as a filter.
47.
48. A.PERITONEAL DIALYSIS-
Peritoneal dialysis is a way to remove waste
products from your blood when your kidneys can
no longer do the job adequately.
49. Goals of PD
• Remove toxic substances andmetabolicwastes
• Reversethe symptoms of uremia
• Reestablish normal fluid and electrolytebalance
• Maintain a positive nitrogenbalance
• Prolong life
• Havethe maximum level of qualityof life
