The eye’s fitness is probably not the first thing that comes to mind when you think of the harmful effects of smoking on one’s body. Smokers put themselves at risk for different kinds of diseases such as lung cancer, heart disease, and eyesight loss.
Wrinkles, creaky elbows, and silver hair aren't the solitary side effects old enough. Think about waterfalls, age-related macular degeneration (ARMD), and glaucoma, which are additional age-related issues that can harm vision. What you should know: While they are more continuous in individuals 50 and over, they are not really present.
To maintain your lifestyle, taking care of your eyesight is important. At least 1 in 6 adults aged 45 or older suffer from eye disorders that threaten vision. The risk of vision changes increases with age.
According to a report from the American Academy of Ophthalmology (AAO), an estimated million in the world will develop an eye disease by the year 2020. Following are some helpful tips to help protect your eyesight as you age.

Whether you’re on the beach, playing golf, or just walking outside, you need to take care of your eyes. Here are a few tips on how to protect your eyes from the sun this summer. For more: https://www.skouraseyeandcosmetic.com
The eyes are the most important and precious part of our human body. What will happen if we lose our eyesight? We will miss the color of this beautiful world if we lose our eyesight. As it is like a window to the world so we should take care of our eyes. For this, we should do a few things a regular basis like showing to an optician, having a sufficient amount sleep and while using computers, giving a steady rest, wearing colored contacts and so on. Let’s have a look at the below tips on what care is needed to keep your eyes in good shape.

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

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

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.

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

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

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.

5. Holding a book too close or
sitting too close to the
television set is harmful to the
eyes
6. Myth!
kids can actually focus up close without
eyestrain better than adults, so they often
develop the habit of sitting right in front of the
television or holding reading material close to
their eyes. However, sitting close to a TV may
be a sign of nearsightedness.
10. Myth!
We wouldn't lose our sense of smell by using
our nose too much or our hearing by using our
ears too much. The eyes were made for seeing.
We won't lose our vision by using our eyes for
their intended purpose.
12. Myth!
Wearing glasses that are too strong or
otherwise wrong for the eyes cannot harm an
adult, although it might result in a temporary
headache. At worse, the glasses will fail to
correct vision and make the wearer
uncomfortable because of blurriness, but no
damage to any part of the eye will result.
15. Myth!
The eyeglasses worn to correct refractive error
will not weaken the eyes any more than they will
permanently "cure" these kinds of vision
problems. Glasses are simply external optical
aids that provide vision to people with blurred
vision caused by refractive errors. Exceptions
are the kinds of glasses given to children with
crossed eyes (strabismus) or lazy eye
(amblyopia). These glasses are used
temporarily to help straighten the eyes or
improve vision. Not wearing such glasses may
lead to permanently defective vision.
18. Myth!
Our eye muscles are meant to allow us to move
our eyes in many different directions. Looking
left, right, up, or down, will not force the eyes to
stay permanently crossed. Crossed eyes result
from disease, from uncorrected refractive error,
or from muscle or nerve damage, not from
forcing the eyes into that position.
21. Myth!
The term "20/20" denotes a person with
excellent central vision. But other types of
vision-such as side vision, night vision, or color
vision might be imperfect. Some potentially
blinding eye disease, such as glaucoma or
diabetic retinopathy, can take years to develop.
During this time, they are harming parts of the
inner eye, but the central vision can remain
unaffected.
24. Myth!
The time to remove a cataract is when it
hinders your eyesight or interferes with your
daily activities. Consult with your
ophthalmologist about your particular situation
and the latest developments in cataract surgery
27. Myth!
Cataracts cannot be removed with laser
surgery. Cataracts are a clouding of the lens in
the eye. In order for vision to be restored, the
cloudy lens must be removed through a surgical
incision and replaced.
29. It is okay to swim while
wearing soft contact lenses.
30. Myth!
No, it is not okay to swim while wearing contact
lenses. That fact is, serious or potentially
blinding eye infections can result from
swimming or even using a hot tub while wearing
contact lenses.
33. Myth!
Two green-eyed parents can have a child with
brown eyes, although it's very rare. Likewise,
two brown-eyed parents can have a child with
green eyes, although this is also uncommon.
39. Myth!
The eye as a whole cannot be transplanted.
Each of our eyes is connected to the brain by an
optic nerve. This optic nerve is highly complex
and is made up of a large bundle of nerve fibers;
like a cable wire. Once the optic nerve is
severed, it cannot be reconnected so eyes
cannot be transplanted.
41. It is not harmful to watch a
welder or look directly at
the sun if you look through
narrowed eyelids.
42. Myth!
ultra-violet light still gets in your eyes and over
time can cause damage to the cornea, lens, and
retina. Exposure to ultra-violet light has been
linked to eye disorders such as macular
degeneration, solar retinitis, and corneal
dystrophies. You should never look at a welder
without the appropriate eye protection because
light from this process can damage your eyes
and/or foreign matter can get into your eyes. As
always, it is best to wear eye protection or
sunglasses to protect your eyes as much as
possible.
45. Eating a lot of carrots will
improve your vision.
46. Some Truth / Myth!
Although it's true that carrots are rich in vitamin A,
which is essential for sight, so are many other foods
(asparagus, apricots, nectarines, and milk, for
example). A well-balanced diet can provide the
vitamin A needed for good vision
49. Myth!
The membrane that covers the white of your eye
(the conjunctiva) also lines your eyelids, so it is
impossible for a contact lens to get lost behind
your eyes
52. Myth!
Although you may not be able to see very well
with them and may get a headache or double
vision, you won’t come to any harm from
wearing glasses that are not your prescription
(unless you’re driving a motor vehicle(.
56. Some Truth!
Unless you have been told specifically by your
optometrist that you can sleep in your contact lenses,
you should avoid this. Your eyes need to breathe whilst
wearing contact lenses, and this is more difficult when
your eyes are closed.
This – and the fact that when you are not blinking your
contact lenses will not move on your eyes as much as
when you are awake – can mean that you are at more
risk of infection if you sleep in contact lenses. Always
follow the guidelines given to you by your optometrist. If
in doubt, take them out.
59. Myth!
The eye is NOT full size at birth but continues to
grow with your child. This growth partially
accounts for refractive (glasses) changes that
occur during childhood.
64. Doctor Said “ You have dry
eye ! “ My complaint is
lacrimation , How Comes?!!.
65. Myth!
Though the most common ocular symptoms are
feelings of dryness, grittiness and burning that
characteristically worsen over the course of the day but
you can have dry eye and you do lacrimate as dry eyes
maybe due to poor quality of tear films and instability on
ocular surface
