Mood disorders are characterized by a sense of loss of control over one's mood and subjective distress. They include conditions like bipolar disorder and recurrent depressive disorder. Bipolar disorder involves alternating periods of mania and depression, while recurrent depressive disorder involves two or more episodes of major depression. Core features of mania include elevated or irritable mood, increased speech, decreased need for sleep, and increased psychomotor activity, while depression is marked by depressed mood, anhedonia, and loss of energy. Treatment involves mood stabilizers, antipsychotics, benzodiazepines, antidepressants, or electroconvulsive therapy. Prognosis depends on factors like age of onset, duration of episodes, and presence of psych
Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks.

Depression (major depressive disorder) is a common and serious medical illness that negatively affects how you feel, the way you think and how you act. Fortunately, it is also treatable. Depression causes feelings of sadness and/or a loss of interest in activities once enjoyed. It can lead to a variety of emotional and physical problems and can decrease a person’s ability to function at work and at home.

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.
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

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.

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.

2. EMOTIONS
AFFECT: MOOD:
Short-lived, emotional Sustained and pervasive
Response to an event
3. Healthy persons experience a wide range of
moods and have a large repertoire of emotional
expressions, feel in control
Mood disorders are a group of clinical conditions
which are characterized a by sense of loss of
control over one’s mood and subjective sense of
distress, impaired interpersonal, social and
occupational functioning
4. History
Hippocrates (400 B.C.) used the terms mania
and melancholia to describe mental
disturbances
Roman physician (30 A.D.) described
melancholia as depression caused by black bile
5. In 1854, Jules Farlet described a condition
called folie circulaire: alternating moods of
depression and mania
In 1899, Emil Kraepelin described manic-
depressive psychosis using most of the criteria
that psychiatrists use now
7. Mania: Clinical Features

Others
7
8. 1. Elevated/ irritable mood:
o Euphoria/ Grade 1: mild elevation of mood, increased
sense of psychological well being and happiness, not in
keeping with ongoing events
o Elation/ Grade 2: moderate elevation of mood, feeling of
confidence and enjoyment, along with increased
psychomotor activity
o Exaltation/ Grade 3: severe elevation of mood, intense
elation with delusions of grandiosity
o Ecstasy/ Grade 4: very severe elevation of mood,
intense sense of rapture or blissfulness
8
9. 2. Increased speech
o Volubility
o Acceleration
o Pressured speech- difficult to interrupt
o Flight of ideas- shift from topic to topic with
cues

o Stupor
9
11. 5. Other symptoms
o Over religiosity
o Over spending/ expansive ideas
o Over familiarity/ disinhibition
o Appearance
o Appetite may be increased, but decreased
food intake due to over-activity
o Decreased need for sleep
13. DEPRESSIVE EPISODE: Clinical
Features
1. Depressed Mood:
Pervasive and persistent sadness
Quantitatively and qualitatively different from
sadness encountered in normal depression or
grief
Varies little from day to day and is often
unresponsive to environmental stimuli
14. 2. Anhedonia:
Loss of interest or pleasure in almost all
activities/ earlier pleasurable activities
Results in social withdrawal
Decreased ability to function in occupational and
interpersonal areas
16. 4. Depressive ideation:
Hopelessness
Helplessness
Worthlessness
Feelings of guilt
Death wishes
Suicidal ideas
17. 5. Psychomotor Activity:
Younger patients (less than 40): slowed thinking and
activity, decreased energy, monotonous voice
Older patients: agitation, marked anxiety, restlessness
Severe depression: stupor
18. 6. Biological functions/ somatic syndrome:
Insomnia
Loss of appetite and weight
Loss of sexual drive
Early morning awakening (atleast 2 hrs)
Diurnal variation
22. Bipolar affective disorder
Characterized by repeated episodes of disturbed
mood and activity levels
Disturbance consisting of elevation of mood,
increased energy and activity on some occasion
and on others of low mood, decreased energy
and activity
Recovery is usually complete in between the
episodes
22
23. Recurrent Depressive Disorder
Recurrent (at least 2 depressive episodes) of
unipolar depression
First episode occurs later than in bipolar, usually
in the 5th decade
Episodes last between 3 to 12 months
Recovery is usually complete
Often precipitated by stressful life events
24. Persistent Mood Disorders
Persistent mood symptoms lasting for more than 2 years
Not severe enough to be labeled as even hypomanic or
mild depressive
Persistent mild depression: dysthymia
Persistent instability of mood between depression and
mania: cyclotymia
