The document summarizes several psychodynamic theories of depression:
1) Freud and others theorized that depression stems from disturbances in early relationships and object loss, and results from turning anger inward.
2) Cognitive theories view depression as arising from negative cognitive schemas and distortions regarding the self, world, and future. Therapy aims to modify these distortions.
3) Learned helplessness theory links depression to feelings of lack of control after uncontrollable events, with improvement dependent on regaining a sense of control and mastery.

Schizophrenia is a group of severe brain disorders in which people interpret reality abnormally. Schizophrenia may result in some combination of hallucinations, delusions, and disordered thinking and behaviour.
Contrary to some popular belief, schizophrenia is not split personality or multiple personality. The word “schizophrenia” does mean “split mind,” but it refers to a disruption of the usual balance of emotions and thinking (Mayo, 2013).
Schizophrenia is a chronic condition, requiring lifelong treatment.

Power of Pictures: Manipulated Beauty In Advertisements That Create Unrealist...karleinnarciso
Extensive editing in advertisements has caused the public to have faulty ideas of what is beautiful, handsome, sexy, etc. Therefore, society has set unrealistic standards to how they classify any other person to be attractive. Changes and modifications completed through Photoshop and additional editing leave children, teens, and adultswith a lifetime of pressure to fit society's set standards and ideals of perfection.
This seminar consists of an introduction to child psychology followed by psychodynamic theories and its applicatioms followed by description and types of fear and anxietry followed by various behaviour rating scales and classification of behaviour

2 Case Reports of Gastric Ultrasound
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.

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
3. 1- Psychodynamic
• The psychodynamic understanding of
depression defined by Sigmund Freud and
expanded by Karl Abraham is known as the
classic view of depression
• Loss of love object>projective identification
and introjection>ambivalence>anger and
turning against self>depression
4. • That theory involves four key points:
• (1) disturbances in the infant mother relationship
during the early oral – late anal predispose to
subsequent vulnerability to depression
• (2) depression can be linked to real or imagined object
loss
• (3) introjection of the departed objects is a defense
mechanism invoked to deal with the distress connected
with the object's loss
• (4) because the lost object is regarded with a mixture
of love and hate, feelings of anger are directed inward
at the self.
5. • Melanie Klein understood depression as
involving the expression of aggression toward
loved ones, much as Freud did
• Bibring regarded depression sets in when a
person becomes aware of the discrepancy
between high ideals and the inability to meet
those goals
• Jacobson saw the state of depression as similar to
a powerless, helpless child victimized by a
punishing parent.
6. • Silvano Arieti observed that many depressed
people have lived their lives for someone else
rather than for themselves.
• Depression sets in when patients realize that
the person or ideal for which they have been
living is never going to respond in a manner
that will meet their expectations.
7. • Heinz Kohut's
• Self psychology
• the developing self has specific needs that
must be met by parents to give the child a
positive sense of self-esteem . When others
do not meet these needs, there is a massive
loss of self-esteem that presents as depression
8. • Bowlby
• believed that damaged early attachments and
traumatic separation in childhood predispose
to depression.
• Adult losses are said to revive the traumatic
childhood loss and so precipitate adult
depressive episodes.
9. 2- Cognitive Theory
• According to cognitive theory, depression results
from specific cognitive distortions present in
persons susceptible to depression.
• Those distortions, referred to as depressogenic
schemata, are cognitive templates that perceive
both internal and external data in ways that are
altered by early experiences.
• Aaron Beck postulated a cognitive triad of
depression that consists of negative views of self,
world and future.
• Therapy consists of modifying these distortions.
10. 3- Learned Helplessness(Seligman)
• connects depressive phenomena to the
experience of uncontrollable events.
• internal causal explanations are thought to
produce a loss of self-esteem after adverse
external events.
• Behaviorists who subscribe to the theory
stress that improvement of depression is
contingent on the patient's learning a sense of
control and mastery of the environment.
