Abdominal pain is one of common problems
encountered by doctors, either in primary or
secondary health care (specialists). It may be
mild, but it may also a life-threatening sign. It
has been estimated that almost 50% adults have
experienced abdominal pain. In general, abdominal pain is categorized
based on the onset as acute or chronic pain.
Sudden onset of abdominal pain that lasts for less
than 24 hours is considered as acute abdominal
pain.

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

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. Definitions
Nausea : Feeling of needing to vomit / unpleasant feeling preceding vomiting
Vomiting/ Emesis : Expulsion of gastric contents by forceful contractions of
abdominal and thoracic muscles
4. Pathophysiology
Neurons in medulla oblongata(area postrema) activated in sequence to induce vomiting
Receptors : D2, 5HT3 , H1, M1
1. Chemoreceptor trigger zone (CTZ) in 4th Ventricle - Drugs , Toxins
2.Vagal/Visceral afferents : Vomiting induced by parts of GI / extra GI
3. Vestibular Nuclei : Motion sickness
4. Higher Centres : Pain , Smell, Memory
Same pathways for Nausea and Vomiting - Intensity of stimulation different
5.
6.
7. Stages of Vomiting
1. Nausea : Unpleasant sensation preceding vomiting associated with
hypersalivation , repetitive swallowing , tachycardia
2. Retching: Gastric/Esophagus relaxation with rhythmic , synchronous
contraction of diaphragm and abdominal (External oblique & Abdominal
rectus) muscles - creates pressure gradient
3. Vomiting : Actual retrograde expulsion of gastric content in response
to the pressure gradient created by retching - glottis closes - prevents
aspiration.
* All three don’t need to be present*
8. Diagnosis of Nausea and Vomiting
The list is - Very large
Every organ pathology can cause Nausea and Vomiting
Can narrow down by history and examination
9. Important History Points
Number of Episodes
Interval between episodes
Timing of episodes
Contents of Vomit - BIle / Blood stained
If blood + : Color of Blood
LMP in reproductive age group females
Prior abdominal surgeries - risk of obstruction due to adhesion formation
11. Physical Examination
Vitals
Hydration status (especially in multiple episodes):
Look for icterus
Complete Abdominal examination - IAPP
If association with vertigo - diff Central vs Peripheral
ECG : If indicated
13. Imaging Indicated if
Central Cause of Vomiting - CT / MRI Brain
CT Chest / Chest X ray - Suspect Esophageal Rupture (Boerhaave syndrome)
Abdominal Imaging if Vomiting secondary to bowel obstruction , kidney stones ,
USG abdomen - if suspecting Pancreatic / Gallbladder / Hepatic/ Appendix / Renal
pathology
14. Treatment in ER
ABC - stabilize the patient
Both ondansetron and prochlorperazine are equally effective to stop vomiting
Antihistamine : Motion sickness / Labrirythitisis induced
Metoclopramide : If Vomiting + Headache
If dehydrated : Oral / IV fluids
Take History and Examination
Labs
Imaging if indicated
15. Complications
1. Hypochloremic, Hypokalemic, Metabolic alkalosis - due to H+ ion loss
Alkalosis → Increased Sodium Bicarb to Kidney (distal Tubules) →
Secondary Hyperaldosteronism causes increased NaCo3 reabsorption and K+
excretion
2. Esophageal tear : Complete: Boerhaave Syndrome
Partial: Mallory Weiss
3. Dehydration : Chronic / massive vomitings
