The document discusses intestinal disease and summarizes key details about the small intestine and histology. It describes that the small intestine length in adults is typically between 3 to 9 meters based on autopsy measurements. It also notes that a duodenal biopsy showing more than 20 lymphocytes indicates inflammation. The document further provides information on various intestinal structures and cells like Brunner's glands, goblet cells, and Paneth cells.

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

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.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Pulmonary Thromboembolism - etilogy, types, medical- Surgical and nursing man...VarunMahajani
Disruption of blood supply to lung alveoli due to blockage of one or more pulmonary blood vessels is called as Pulmonary thromboembolism. In this presentation we will discuss its causes, types and its management in depth.
2. • Small intestine measurements taken at
autopsy ( cadaver examination ), because of
endoscope and coloscope cant reach small
intestine (iluem) so its suggests that adult
lengths of small intestine between 3 & 9
meters.
3. Histology of small intestine
• Once we have a duodenal biopsy we have to count
lymphocyte, if they are more than 20 mean
inflammation
4.
5. Why ?because the presence of goblet cells ( which secretes
mucus along the whole intestines ) is not sufficient to protect
the duodenum from the gastric acids .
6. Brunner’s glands
• tuboalveolar( or tubule-acinar ) glands .
• have ducts that open directly into the crypts
of lieberkuhn .
• Has Urogastrone : an enzyme that is secreted
to the blood ,it goes to the parietal cells and
inhibits their acid secretion .
7. folding of lamina propria and epithelium
Goblet cells : (uni-cellular ) that
secrete mucinogen (
mucus precursor ) to lubricate
the small intestine
I , S cells
Paneth cells (defense
cell) :Apical eosinophilic
granules: secrete
lysozymes
enterocyte
Intestinal gland
12. • As we going from duodenum to ileum number
of lymphocytes are increased
• why ?
• Coz the food will converted to fecal material
>> that’s increase number of bacteria>> and
should be balance between bacteria and
inflammatory cells .
13. • Atresia : absence of canalization where as
stenosis is narrowing of lumen >
• Duodenal Atresia is associated with Down syndrome
failure to recanalize
(trisomy 21).
14. there is a reminant of the yolk sac
“persistence”
15.
16. • Located in distal ileum usually within (2 feet )
• the blend segment or pouch is about (2inch)
long.
• most common malformation of GIT (2% of
population ).
• true diverticulum its mean that bulging part
have 3 layers not 2(false)” more common”.
The complication of this disease are pain and bleeding which may mimic
appendicitis therefor , during appendectomy , ileum should be checked for
presence of meckel's diverticulum , if it is found to be present it
should be removed with appendix
its role of 2
17. • Heterotopic rests of gastric mucosa and
pancreatic tissue (rare ) .
• heterotopic means displacement of an organ
from its normal location
infracolic compartment.
supracolic compartment.
18. Meckel diverticula may contain ectopic gastric mucosa (which can
ulcerate surrounding mucosa with pain and bleeding) or ectopic
pancreas (which is of no consequence unless it forms a mass large
enough to predispose to intussusception).
20. Volvulus
• Mostly in small intestine; large intestine
especially sigmoid and cecum.
• Rare.but
Most common
In adults.
21. The nervous system in GI has 2 networks
(plexuses) of nerves :(Enteric Nervous System):
• 1.Meissener’s submucosal plexus:-
- related to the secretory function.
- it Stimulates the contraction of muscularis
mucosa and the contraction of the endothelial
and other cells in ( glands and blood vessels )
- Neurotransmitter Vasoactive Intestinal
Peptides (VIP) and Nitric Oxide (NO) cause the
smooth muscle contraction and thus increase
blood flow to intestinal epithelium.
22. • 2. Auerbach’s myenteric plexus أورباخ=قوي
-within the muscularis externa > (between the
inner circular and the outer longitudinal
>movement.
-They are excitatory , but some are inhibitatory
(They secrete (VIP) which inhibit intestinal
sphinctre muscles like: pyloric sphinctre &
ileocecal valve .
32. • Classification of diarrheal disorders :-
• 1- Secretory diarrhea :-
-Secretory diarrhea means that there is an increase in the
active secretion, or there is an inhibition of absorption.
-There is little to no structural damage
-The most common cause of this type of diarrhea is a
cholera toxin that stimulates the secretion of anions,
especially chloride ions. Therefore, to maintain a charge
balance in the lumen, sodium is
carried with it, along with water
33. • 2- Osmotic diarrhea
• occurs when too much water is drawn into the
bowels. If a person drinks solutions with
excessive sugar or excessive salt, these can
draw water from the body into the bowel and
cause osmotic diarrhea.
• Osmotic diarrhea can also be the result of
maldigestion :(e.g., pancreatic disease or
Coeliac disease), in which the nutrients are
left in the lumen to pull in water.
• Or it can be caused by osmotic laxatives
(which work to alleviate constipation by
drawing water into the bowels)
34. • 3- Exudative diarrhea:-
• Exudative diarrhea occurs with the presence
of blood and pus in the stool. This occurs with
inflammatory bowel diseases,( bacterial).
• 4- Malabsorption diarrhea :-
• unabsorbed nutrients & fat.
• 5- Deranged motility diarrhea :-
• decreased intestinal retention time; decreased
motility. WHY??
• Because it leads to bacterial overgrowth
infection diarrhea
