This document discusses the ethical principles and codes that guide the optometry profession. It begins by explaining that a profession requires having a code of ethics that guides practitioners' decisions and standards. The major ethical principles for healthcare - beneficence, non-maleficence, respect for autonomy, and justice - are described. Additional principles of confidentiality, protection of the vulnerable, and collegiality are also discussed. However, the document notes that applying these principles can sometimes cause ethical dilemmas, as principles may conflict in certain situations. Overall, the document emphasizes that ethics in optometry are meant to protect patients and guide practitioners.

Ethical considerations in molecular & biotechnology researchDr Ghaiath Hussein
A lecture presented by Dr. Ghaiath Hussein in University of Khartoum for the students of the MSc programme in Genetics/Molecular Biology.
Session 1 (Introduction): Definition of ethics, bioethics and medical ethics.
What is an ethical issue?
International approaches to medical ethics
Islamic approaches to medical ethics
What is Ethics
Ethics is not a religion
Ethics are not the feelings
Ethics is not a law
Neither it follows any law
Ethics is not a science
Ethics is not a collection of norms that a specific culture accepts
Beneficence
Beneficence is action that is done for the benefit of others
For example, a patient who has had bypass surgery may want to continue to smoke or a patient with pneumonia may refuse antibiotics. In these situations the autonomous choice of the patient conflicts with the physician’s duty of beneficence and following each ethical principle would lead to different actions.
The ethics of performance monitoring-private sector perspectiveDavid Quek
Increasingly medical practice is coming under intense scrutiny as to what is appropriate and affordable care, including serious considerations of patient safety issues and protection. Medical professionalism must be consciously adhered to as we try and find the best health care for our patients at the best value and outcomes for our patients themselves, and also for society at large. In view of escalating health care costs, physician autonomy to practice as he or she likes or deems fit has now come under siege with more and more performance monitoring, not just for appropriateness, but also for outcomes, necessity and cost-effectiveness. Physician' vested interests must be tempered with evidence-based benefits or at least be associated with no increase in harm or incur affordability issues. Fraudulent physician malfeasance are now being uncovered via whistle-blowers, or through greater more meticulous audit of various validated performance measures, and those physicians found to have flouted these due to pecuniary self-interests, overuse of tests or procedures have been found guilty and sanctioned with heavy fines, return of reimbursements as well as imprisonment, and erasure from medical registries and the removal of license to practice.
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.
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.

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

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. The use of the word ‘profession’ has expanded
so far beyond its original meaning
It is not uncommon to find the term ‘professional’
misused to describe sportsmen, tradesmen, and even
politicians
Common understanding that ‘professionals’ are
doctors, lawyers and teachers
A fundamental distinction between a
profession and any other occupation, is that
individuals engaged in a profession have an
ethical obligation to whomever they offer their
services.
In other words, a profession is required to have
a Code of Ethics
3. Optometry ranks amongst the leading
healthcare professions
Various national Codes of Ethics exist for the
Optometry profession
Tracked back to one of the original sources of
medical ethics in the Western world: The famous
oath of Hippocrates
Original oath do not form part of medicine and
healthcare today and it includes statements that would
not concord with modern practice:
Pledge to remain chaste and religious and never to procure
abortion
4. Hippocrates oath has been transposed through
history
It was incorporated into the Declaration of Geneva
(1948) following the Second World War.
The following year, in response to Nazi War crimes,
the World Medical Association adopted the
International Code of Medical Ethics
This has formed the basis of ethics of a number of
healthcare professions.
5. The ethical codes contain guiding principles
Help practitioners in their decisions and in
practicing in accordance with a set of standards that
are expected of a healthcare practitioner
The four major ethical principles in healthcare
are:
Beneficence
Non-maleficience
Respect for autonomy
Justice
6. Beneficence
Striving to do good and to do the best for every patient
The practitioner has a duty of care to every patient
The objective to do good so that every patient leaves the
practice in a better state than when they entered, and not in a
worse condition
Non-maleficience
Directly traceable to the Hippocratic oath “above all to do
no harm” i.e. this is about the avoidance of harm
Requires balancing risks and benefits of treatment and
making decisions that will optimize the benefits and
minimize the risks of harm
7. Respect for autonomy
Requires a practitioner to respect the choices and
decisions that a patient makes about his/her own health
Involves keeping the patients informed of their condition,
treatment choices and options so that decisions made are
based on pertinent facts
Justice
Entails being fair to all patients in a way that transgresses
legal justice
Includes deciding how much time is spent on a patient,
how many and what types of resources are devoted to
treatment of that patient and how this compares to the
time and resources distributed to other patients
8. In addition to the four ethical principles the
following ethical principles have been included
to form the ethical principles that should guide
optometric practice :
Principles of confidentiality
Protection of the vulnerable
Collegiality
9. Principles of confidentiality
Non-disclosure of patient details and health records
To respect the privacy and preserve the dignity of
each patient
Traced directly to the Hippocratic oath: “Whatever I
see or hear, professionally or privately, which ought
not to be divulged, I will keep secret and tell no one”
10. Protection of the vulnerable
Standing up for the rights of those who may be
unable to speak or act for themselves
Children, the frail elderly, and patients who are unable
to make decisions for themselves
These patients may require a degree of protection
that extends beyond the usual duty of care
Collegiality
Calls for support of colleagues and fellow
practitioners and professionals
Mutual respect & understanding for fellow
optometrists, for other professionals and for their
respective roles in the health care team
This is the only ethical principle that does not apply
to patients but to the way practitioners treat one
another
11. The ethical principles may appear simple to
follow and understand
Yet for each one of them, situations may arise,
that will make it difficult to apply these
principles
These principles are essential tools for ethical
practice, but if applied too rigidly they can be
problematic
No principle can be applied absolutely
12. Beneficience dilemma:
How good is good enough?
Should a practitioner become so completely selfless
that they commit their entire life and all available
time to helping patients at the expense of a private
life and duties to family?
The difficulty with beneficience is that it is limitless
and every practitioner needs to decide how far they
want to take this principle
13. Non- Maleficence dilemma:
Not limitless but may be limiting
No practitioner will ever set out to harm a patient
Certain practice methods will incur a risk of harm
For example: Contact tonometry and the prescription of a
contact lens can result in unwanted side effects
To apply this principle would require a practitioner to
abandon all practice methods with the potential of
harm, no matter how minimal the harm or how small
the risk
14. Respect for Autonomy dilemma:
A legally blind patient who refuses to wear glasses
and is still continuing to drive
Is it ethical to respect this patient’s autonomy??
Can the optometrist always respect the choice of a
patient whose behavior may be unreasonable and
potentially dangerous?
15. Justice Dilemma:
How to decide the basis of this fairness and how
time and resources should be distributed?
All patients should be given half an hour of an
optometrists' time but this may prove to be too
inflexible
Some patients may need less time and some may need
considerably more time
16. Collegiality dilemmas:
It is easy to practice with those who have similar interests
and outlooks
Difficult when working with fellow optometrists who have
different perspectives, opinions, attitudes, and behaviors
If the colleague is practicing ethically, personal differences
should be put aside
Collegiality also has no place for prejudice or professional
jealousy
If a colleague is behaving in a manner that may be
inappropriate for a professional, collegiality cannot be
used as an excuse to protect what is wrong. Help
should be offered but in some cases a colleague may
need to be reported.
17. Confidentiality
Can be compromised when a patient discloses to a
practitioner something that may have serious
ramifications for the patient and potentially for
others
For ex: it can be difficult for an optometrist to decide
whether or not to keep confidential the details of a
patient who admits to having AIDS but asks the
optometrist to keep this secret from his (the patient’s)
wife.
18. Protection of the vulnerable dilemmas:
Must decide how far this protection can extend
Should the parent of a child patient who appears
with multiple bruising be reported even though the
matter has nothing to do with eye care?
Reporting such a matter to social services may result in
innocent parents having to defend themselves against
charges of child abuse.
Not reporting, may leave vulnerable child open to
further risk of harm.
19. There are circumstances that cause principles to
conflict
i.e. applying one principle will almost certainly require
disregarding of another principle
The practitioner is faced with an ethical dilemma
Example: A case of an overweight diabetic who
presents to the optometrist with early signs of
diabetic retinopathy
The patient is a smoker and refuses to stop smoking
Beneficience requires the practitioner to do his/her best.
In this case the best is to do whatever possible to alter the
patient’s lifestyle
If the patient continues to smoke, then the practitioner is
obligated to respect the autonomy of this patient
The autonomy of the patient and respect for his choices
presides over a more active application of beneficence
20. Unlike laws and regulations, the principles of
ethics are flexible and their application
depends on each individual practitioner
Each optometrist has:
The responsibility of developing their own personal
ethical standards
The expectation of possessing the self-discipline to
practice in accordance with these standards
It is these responsibilities and expectations
that are the hallmarks of a profession
21. The optometric profession has long recognized its
ethical responsibilities to patients, colleagues,
other health care professionals, and the public.
The American Optometric Association (AOA) has
historically provided statements of ethical
aspirations and standards of expected professional
behavior.
The Code of Ethics and The Optometric Oath are
the current documents guiding the ethical
behavior of AOA members.
These documents are frequently expanded on through
policy resolutions adopted by the House of Delegates
http://www.aoa.org/x4877.xml
22. It shall be the ideal, resolve, and duty of all optometrists:
TO KEEP their patients' eye, vision, and general health paramount at all
times;
TO RESPECT the rights and dignity of patients regarding their health
care decisions;
TO ADVISE their patients whenever consultation with, or referral to
another optometrist or other health professional is appropriate;
TO ENSURE confidentiality and privacy of patients' protected health and
other personal information;
TO STRIVE to ensure that all persons have access to eye, vision, and
general health care;
TO ADVANCE their professional knowledge and proficiency to maintain
and expand competence to benefit their patients;
TO MAINTAIN their practices in accordance with professional health
care standards;
TO PROMOTE ethical and cordial relationships with all members of the
health care community;
TO RECOGNIZE their obligation to protect the health and welfare of
society; and
TO CONDUCT themselves as exemplary citizens and professionals with
honesty, integrity, fairness, kindness and compassion
http://www.aoa.org/x4878.xml
23. With full deliberation I freely and solemnly pledge that: I will practice the art
and science of optometry faithfully and conscientiously, and to the fullest scope of my
competence. I will uphold and honorably promote by example and action the highest
standards, ethics and ideals of my chosen profession and the honor of the degree, Doctor of
Optometry, which has been granted me. I will provide professional care for those who seek
my services, with concern, with compassion and with due regard for their human rights and
dignity.
I will place the treatment of those who seek my care above personal gain and strive to
see that none shall lack for proper care.
I will hold as privileged and inviolable all information entrusted to me in confidence by
my patients.
I will advise my patients fully and honestly of all which may serve to restore, maintain
or enhance their vision and general health.
I will strive continuously to broaden my knowledge and skills so that my patients may
benefit from all new and efficacious means to enhance the care of human vision.
I will share information cordially and unselfishly with my fellow optometrists and other
professionals for the benefit of patients and the advancement of human knowledge and
welfare. I will do my utmost to serve my community, my country and humankind as a
citizen as well as an optometrist.
I hereby commit myself to be steadfast in the performance of this my solemn oath and
obligation
http://www.aoa.org/x4881.xml
24. Astigmatism
A condition in which the cornea's curvature is asymmetrical (the
eye is shaped like a football or egg instead of a baseball); light rays
are focused at two points on the retina rather than one, resulting in
blurred vision. Additional symptoms include distorted vision,
eyestrain, shadows on letters, squinting and double vision
Anisometropia
A condition where the eyes have a significantly different refractive
power from each other, so the prescription required for good vision
will be different for each eye.
Amblyopia - Also called lazy eye.
Undeveloped central vision in one eye that leads to the use of the
other eye as the dominant eye. Strabismus is the leading cause,
followed by anisometropia.
There are no symptoms. The patient may be found squinting and
closing one eye to see; there may be unrecognized blurred vision in
one eye and vision loss.
http://www.opted.org/files/public/Eyes_Have_it_Career_Guide_-_FINAL_02_10.pdf
25. Refraction
The test performed during an eye exam to determine the
eyeglass lens powers needed for optimum visual acuity.
An automated refraction uses an instrument that does
not require the patient to respond.
A manifest refraction is the manual way to determine
the best lenses, by placing various lenses in front of the
patient's eyes and asking, "Which is better, lens A or lens
B?“
Strabismus
A misalignment of the eyes
The eyes don't point at the same object together. Crossed
eyes (esotropia) are one type of strabismus; "wall-eyes"
(exotropia) are another. The exact cause is unknown, but
appears to be a problem with the eye muscles.
Strabismus can affect depth perception.
http://www.opted.org/files/public/Eyes_Have_it_Career_Guide_-_FINAL_02_10.pdf
26. Intraocular pressure (IOP)
Eye pressure, as determined by the amount of aqueous
humor filling it.
High IOP (ocular hypertension) can be a sign of
glaucoma
intraocular lens (IOL)
Artificial lens that a cataract surgeon places in a
patient's eye after removing the eye's natural lens.
Like a contact lens, it has a built-in refractive power
tailored specifically to the patient's visual condition.
http://www.opted.org/files/public/Eyes_Have_it_Career_Guide_-_FINAL_02_10.pdf
27. Low vision
Also called partial sight.
Sight that cannot be satisfactorily corrected with glasses,
contacts, or surgery.
Low vision usually results from an eye disease such as
glaucoma or macular degeneration.
Age-related macular degeneration (AMD)
Disorder characterized by changes in the eye's macula that
result in the gradual loss of central vision.
The exact cause is unknown, but appears to be related to a
genetic predisposition, smoking and several other risk
factors.
Central vision may be blurred, distorted or shadowy before
vision loss occurs.
