- Geriatric patients are defined as those aged 65 years and older. They experience various physiological changes with aging that impact anesthesia management. These include changes to the cardiovascular, respiratory, gastrointestinal, and neurological systems. Pre-operative evaluation of geriatric patients should consider their co-morbidities, functional status, and cognitive abilities. During anesthesia care, extra precautions are needed to prevent issues like hypotension, hypothermia, delirium and impaired drug metabolism that commonly affect the elderly.

Preanesthetic checkups in Geriatric PopulationReema Chaudhary
There are many important physiological age related changes in geriatric population,so before going to any surgery we plan to do PAC ,this presentation defines all the important anesthetic consideration worth keeping in mind.
Geriatric anesthesia with special consideration Petrus IitulaPetrus Iitula
With age, comes changes in normal physiological functions of the body and different diseases are picked up in certain population groups as we age. all this factors predisposes the geriatric population to certain complications once under anesthesia. Hence anesthetic preparation for the geriatric patients is needed to avoid mortality and morbidity in this population.

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

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

ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

40. -GERIATRIC PATIENTS
-PSYCHOLOGICAL CHANGES
--1-Loss of physical strength and abilities
--2-Loss of Mental abilities (confusion,
Dementia)
--3-Loss of relationships when companions
or friends die
--4-Loss of self –esteem
--5-Loss of body image
--6-Loss of independence
--7-Loss of control over life
plans and lifestyle
41. -GERIATRIC PATIENTS
-ANESTHETIC IMPLICATION
--1-Geriatric patients with psychological
changes are difficult to handle for
history taking and physical examination.
--2-Anesthesiologist should calm,
co-operative and always take help of
family member in pre-assessment
43. -GERIATRIC PATIENTS --THE CAT IN THE HAT
--I CAN NOT SEE
--I CAN NOT SEE
--I CAN NOT CHEW
--I CAN NOT SCREW
--=OH MY GOD, WHAT CAN I DO ?
--MY MEMORY SHRINKS
--MY HEARING STINKS
--NO SENSE OF SMELL
--I LOOK LIKE HELL
--=MY MOOD IS BAD - CAN YOU TELL ?
--MY BODY IS DROOPING
--HAVE TROUBLE WITH POPPING
--THE GOLDEN YEARS GONE
--WITH LOSS OF BONE
--I AM EVERY WHERE
--HANDLE WITH CARE
46. -GERIATRIC PATIENTS
--BEST PRACTICES
FOR
COMMUNICATION
WITH
OLDER ADULTS
--Anesthesiologist should make the assessment face-to-face, allowing
the patient to see lip movements when speaking; this is particularly
important if the patient has a hearing problem.
--Voice tone should be clear, slow and slightly louder than usual.
--The anesthesiologist should understand by asking leading questions
from the patient or caregiver or companion.
--One question should be asked at a time, allowing sufficient time
for patients responses. Even healthy older adults may take a
little longer to process a question and frame a response.
--Communication should be modified to match the individual’s
learning style and incorporate language the patient uses, avoiding
complex medical terminology, acronyms, and abbreviations.
--If the patient has cognitive impairment, assessment questions
should be verified with the assistance of the family members
or primary caregiver.
47. -GERIATRIC PATIENTS
HOW TO COMMUNICATE WITH
DEAF ,AND OLD PATIENTS
--1-50% of Geriatric patients are having
Hearing Problems. It is some times very
difficult to communicate with them
--2-So our Medical Stethoscope will help
us by reversing the ends
--3-Patients will communicate very nicely
IT IS SIMPLE BUT VERY USEFUL WAY
48. -GERIATRIC PATIENTS -COMPLETE MEDICAL HISTORY
--1-CVS and RS complaints
present and past
--2-Routine activities
--3-Mental and Physical status
--4-Dependency
--5-Associated diseases
--6-Drug History / Polypharmacy
--7-BMI / Nutrition
--8-Past History Op / Ane Experience
--9-Any alternative Medicine
--10-Allergy
--11-Social and Family History
--1-Any Habits like
Tobacco / Smoking / Drinks
--2-Sleep Patterns
ALWAYS SEE FOR
--3-Depression
--4-Malnutrition
--5-Immobility
--6-Dehydration
--7-Denture
--8-Pace Maker
--9-Any joint Replacement
--10-Any Anti Depression drug
49. -GERIATRIC PATIENTS
-PRE-OPERATIVE EVALUATION contd.
--1-See weather Geriatric patient is able to
perform Mental Social and Physical activities
--2-All patients must be examined in presence of
Family members or friends or a Guardian
--3-Always see for polypharmacy because these
groups mostly suffer from 2 to 3 systemic
diseases
--4-Note the cognitive functions status to compare
pre and post operative changes
50. -GERIATRIC PATIENTS
DIFFERENT RISK FACTOR SCALES
ARE AVAILABLE FOR
PRE - ASSESSMENT
--1-APCHE:- (Acute Physiological and chronic
Health evaluation)for critically ill patients
--2-POSSUM:- (Physiological and Operative
severity Score for enumeration of Mortality
and Morbidity) for surgical patients.
--3-GOLDMAN SCALE:- This is of Cardiac risk of
patients in Non cardiac surgeries
51. -GERIATRIC PATIENTS
-GENERAL PHYSICAL EXAMINATION
--1-Physical examination of old patient always
to be done n warm area
--2-General Appearance
--3-Head to Toe Examination for pressure points,
a-Joints
b-Hearing and
c-Vision impairment
--4-Height / Weight
--5-Neck mobility, and Spine Deformity, teeth
loss
52. -GERIATRIC PATIENTS
SEE FOR
--1-Difficult intubation
--2-Difficult Regional Anesthesia
--3-Difficult Nerve Blocks
--4-Difficult I/V lines
--5-Weight for BMI
--6-Drugs Regularity
--7-Relatives attitude and
Responsibility
EXAMINE FOR
--1-Vital Signs
--2-CVS and RS system
--3-Oxygen saturation
--4-Pain Threshold
--5-Breathing pattern
--6-Breath Holding Time
--7-Clock Drawing Test
--8-Trail Making test
-PHYSICAL EXAMINATION
53. -GERIATRIC PATIENTS
-INVESTIGATIONS
ROUTINE
--1-Complete Hemogram
--2- FBS / HbA1C
--3- ECG
--4- X ARY CHEST
--5- RENAL FUNCTION TESTS
--6- LIVER FUNCTION TESTS
--6b- with proteins
--(All above investigations are very
important rather must be for routine
anesthesia administration)
SPECIAL INVESTIGATIONS
--1-According to positive Medical History
and Disease
--a- Echocardiography for CVS
--b-Spirometry and for RS and
--c-Sonography for GIT and KUB
OTHER TESTS WOULD BE CARRIED OUT
ACCORDING TO THE SYSTEM AFFECTED
e.g CVS / RS / GIT / URINARY SYSTEMS
54. -GERIATRIC PATIENTS
PLAN AFTER COMPLETE ASSESSMENT OF
GERIATRIC PATIENT
--1-It is very important to determine the patient’s status and physiologic
reserve in the pre – anesthetic evaluation.
--2-The risk from anesthesia is more related with the presence of
co-existing disease than with the age of the patient
--3-The condition should be optimized before surgery with good nutrition
Pharmacological support system wise and done without any delay
as long delays increase Morbidity rates are expected to increase
64. -GERIATRIC PATIENTS
IMPORTANT POINTS TO REMEMBER ABOUT
GERIATRIC PATIENTS
--1-The circulating level of Albumin decreases
(Binding Protein for Acidic Drugs)
--2-While the level of α-1 acid glycoprotein
increases (binding protein for basic Drugs)
65. -GERIATRIC PATIENTS
--IMPORTANT POINTS TO REMEMBER ABOUT
GERIATRIC PATIENTS
--1-The decrease in total body water
--This leads to a reduction in the central compartment
and increased sodium concentrations after a bolus
administration of a drug
--2-Increase in body Fat
--This results in a greater volume of distribution of drugs
and prolonging their action
--3-Aging effect on Hepatic and Renal Functions
--Drug Metabolism may be altered
66. -GERIATRIC PATIENTS
SO FOR
DOSE AND DURATION OF DRUGS
ONE HAS TO REMEMBER THAT
ALTERED BODY COMPOSITION
IN OLD AGE LEADS TO:-
--1-Decrease Blood volume
--2-Decrease Muscle mass
--3-Decrease Plasma proteins
--4-Decrease circulatory time
--5-Decrease Metabolism and clearance
67. -GERIATRIC PATIENTS
-DOSES OF ANESTHETIC AGENTS
--1-Sedations - Decrease
--2-Induction agents – Decrease (almost 50%)
--3-Opioids – Decrease (Here Remifentanil is most potent)
--4-Muscle relaxants – No change
--5-Inhalation agents – Reduce MAC (Ideal is 1.5 MAC)
--6-Local Anesthetics – Decreases
NOTE:-
--Ideal inhalation agent for old age is Desflurane ideal muscle
relaxants for old age is Atracurium induction agents are used
according to pre-assessment and risk of surgery
68. -GERIATRIC PATIENTS
-REGIONAL AND PERIPHERAL NERVE BLOCKS
--1-The duration of analgesia may be prolonged
with age advancing on the Baricity, dose and
strength of the local Anesthetic solution
--2-When GA carries great risk for the patient
Regional Anesthesia or Nerve Blocks provide
an excellent solution
69. -GERIATRIC PATIENTS
TO SUM UP
PHARMACOLOGY OF ANESTHESIA DRUGS
--1-The elderly are more sensitive to anesthetic agents and
generally require smaller doses for the same clinical
effect, and drug action is usually prolonged.
--2-One Arm Brain circulation is about 20 seconds and drug
to reach their maximum effect requires 3 to 4
circulations. And in old age this time is upto 90 seconds.
So drug dose requirement is less
71. -GERIATRIC PATIENTS
-SOME WORDS FOR FLUID ADMINISTRATION
--1-Elderly patients compensate poorly for Hypovolemia
and over transfusion
--2-After one liter of infusion, better replace blood loss
with blood transfusion
--3-Liberal oral intake of fluids allowed 2 to 3 hours
pre-operatively
--4-Always keep in mind about elderly compromised
Heart, poor organ perfusion and reduction in GFR
for I/V fluid administration
74. -GERIATRIC PATIENTS
Elderly patients are vulnerable and particularly sensitive to the
stress of Trauma, Hospitalization, Surgery and Anesthesia
ANESTHESIOLOGISTS MUST REMEMBER AND DO
--1-Understanding old age physiology and pre-operative management
of co-existing disorders
--2-Meticulus pre-operative assessment of organ function and reserve
--3-Careful Drug Selection and Dose titration
--4-Careful Fluid Therapy
--5-Selection between RA and GA
--6-Proper psychological preparation and management
--7-Good post operative pain control
