This document discusses various hemodynamic disturbances including congestion, hemorrhage, and edema. It defines these conditions and describes their morphological features. Congestion is a passive increase in blood volume due to impaired outflow, causing tissues to appear cyanotic or red-brown. Hemorrhage can be external or internal, and results from vessel rupture. Edema is the accumulation of fluid in interstitial spaces or cavities, and can be localized or generalized. It results from increased hydrostatic pressure, decreased oncotic pressure, lymphatic obstruction, sodium retention, or inflammation. The morphology of congestion, hemorrhage and edema in various organs is described.

Title: Edema Congestion: Understanding the Mechanisms and Clinical Implications
Introduction:
Edema congestion is a pathological condition characterized by the abnormal accumulation of fluid within tissues or body cavities, leading to swelling and impaired tissue function. It is a complex physiological process that can arise due to various underlying factors and may manifest in different regions of the body. Understanding the mechanisms and clinical implications of edema congestion is crucial for healthcare professionals to effectively diagnose, manage, and treat patients presenting with this condition.
I. Mechanisms of Edema Congestion:
A. Increased Capillary Hydrostatic Pressure:
- Elevated pressure within the capillaries due to factors such as venous obstruction, heart failure, or localized inflammation.
- Higher hydrostatic forces cause an excessive filtration of fluid from the capillaries into the interstitial spaces, contributing to tissue swelling.
B. Decreased Plasma Oncotic Pressure:
- Reduction in plasma protein levels, particularly albumin, results in decreased oncotic pressure.
- Lower oncotic pressure leads to reduced fluid reabsorption from the interstitial spaces back into the capillaries, exacerbating fluid accumulation.
C. Lymphatic Obstruction or Insufficiency:
- Impaired lymphatic drainage due to lymphatic vessel obstruction, surgical intervention, or congenital malformations.
- Inadequate lymphatic clearance results in the retention of interstitial fluid, leading to edema.
D. Sodium and Water Retention:
- Dysregulation of sodium and water balance in conditions like kidney dysfunction, cirrhosis, or hormonal imbalances.
- Sodium retention leads to increased osmotic pressure, causing water to accumulate in the interstitial spaces.
II. Clinical Implications:
A. Peripheral Edema:
- Swelling predominantly in the extremities, commonly observed in conditions such as heart failure, deep vein thrombosis, or venous insufficiency.
- Patients may experience discomfort, reduced mobility, and skin changes due to chronic edema.
B. Pulmonary Edema:
- Accumulation of fluid in the lungs, often resulting from heart failure, acute respiratory distress syndrome (ARDS), or pneumonia.
- Respiratory compromise, cough, and shortness of breath are common symptoms requiring urgent medical intervention.
C. Cerebral Edema:
- Swelling within the brain due to trauma, stroke, or tumors.
- Potentially life-threatening, as it can lead to increased intracranial pressure, neurological deficits, and herniation.
D. Ascites:
- Edema within the peritoneal cavity, commonly associated with liver cirrhosis, malignancies, or congestive heart failure.
- Abdominal distension, discomfort, and respiratory compromise are typical manifestations.
III. Diagnostic Approach:
A. Clinical Examination:
- Careful assessment of the patient's medical history, physical symptoms, and risk factors.

Report Back from SGO 2024: What’s the Latest in Cervical Cancer?bkling
Are you curious about what’s new in cervical cancer research or unsure what the findings mean? Join Dr. Emily Ko, a gynecologic oncologist at Penn Medicine, to learn about the latest updates from the Society of Gynecologic Oncology (SGO) 2024 Annual Meeting on Women’s Cancer. Dr. Ko will discuss what the research presented at the conference means for you and answer your questions about the new developments.
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.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

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

2. Hemodynamic disturbances
• Problems related to the flow of blood and
consequences thereof. Include:
• Hyperemia /congestion
• Hemorrhage
• Edema
• Thrombosis
• Embolism
• Infarction
• Shock
3. Hyperemia
• An active process resulting from
augmented tissue inflow due to arteriolar
dilatation causing increased volume of
blood in a particular tissue.
• Area is red due to oxygenated blood
• E.g. exercise, inflammation
4.
5.
6. CONGESTION
• A passive process resulting from impaired
outflow of venous blood from a tissue causing
increased volume of blood in that tissue.
• Poor oxygenation – blue red in color cyanosis
hypoxia - cellular degeneration - secondary
fibrosis
• Elevated intravascular pressure- capillary
rupture - focal hemorrhage
• Cardiac failure, local venous obstruction.
7. MOPRHOLOGY
Gross: cut surfaces are wet and hemorrhagic
Microscopic:
Acute Pulmonary congestion
alveolar capillary dilatation with blood
alveolar septal edema
intra alveolar hemorrhage.
Chronic Pulmonary congestion
Septa thickened and fibrotic, alveolar
septal edema.
Hemosiderin laden macrophages in
alveolar spaces - heart failure cells.

• Two types
• 1. Localized edema involves an increase of fluid
in extracellular space locally
• 2. Generalized edema is due to increase in both
total body water and sodium
• Anasarca: Severe and generalized edema with
subcutaneous swelling
19. Fluid movement in body
• There is free exchange of water, electrolytes and
small molecules between intra and extracellular
compartments of body.
• Primary site - capillaries
