Optimization techniques are used to find the best formulation and manufacturing process. Traditional optimization varies one variable at a time, while modern techniques use systematic experimental design. Different optimization methods are applied depending on the problem, such as whether the problem has constraints or independent variables. Optimization helps reduce costs and errors while improving safety, reproducibility, and time efficiency in pharmaceutical development and manufacturing.

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.

Tom Selleck Health: A Comprehensive Look at the Iconic Actor’s Wellness Journeygreendigital
Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
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 Case Reports of Gastric Ultrasound
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

2. The term Optimize is defined as to make perfect , effective , or as functional
as possible.
It is the process of finding the best way of using the existing resources while
taking in to the account of all the factors that influences decisions in any
experiment
Traditionally, optimization in pharmaceuticals refer to changing one variable
at a time, so to obtain solution of a problematic formulation.
Modern pharmaceutical optimization involves systematic design of
experiments (DoE) to improve formulation irregularities.
In the other word we can say that –quantitate a formulation that has been
qualitatively determined . It’s not a screening technique.
4. o Yield the “Best Solution” within the domain of study.
o Require fewer experiments to achieve an
optimal formulation.
o Can trace and rectify problem in a remarkably
easier manner.
6. PROBLEM
TYPES
Unconstrained
• In unconstrained optimization problems there are no restrictions.
• For a given pharmaceutical system one might wish to make the
hardesttablet possible.
• The making of the hardest tablet is the unconstrained optimization
problem.
Constrained
• The constrained problem involved in it, is to make the hardest tablet
possible, but it must disintegrate in less than 15 minutes.
7. • Independent variables : The independent variables are under the
control of the formulator. These might include the compression force
or the die cavity filling or the mixing time.
• Dependent variables : The dependent variables are the responses or
• the characteristics that are developed due to the independent
variables. The more the variables that are present in the system the
more the complications that are involved in the optimization.
8.
9. Classical optimization is done by using the calculus to basic problem to find
the maximum and the minimum of a function.
The curve in the fig represents the relationship between the response Y and the
single independent variable X and we can obtain the maximum and the minimum.
By using the calculus the graphical represented can be avoided. If the relationship,
the equation
for Y as a function of X, is available.
Y = f(X)
11. (EVOLUTIONARY
OPERATION)
Make very small changes in formulation repeatedly.
• The result of changes are statistically analyzed.
• If there is improvement, the same step is repeated until
further change doesn’t improve the product.
Where we have to select this technique?
This technique is especially well suited to a production situation. The
process is run in a way that is both produce a product that meets all
specifications and (at the same time) generates
information on product improvement.
12. Advantages:
• generates information on product development.
• predict the direction of improvement.
• Help formulator to decide optimum conditions for the formulation
and process.
Limitations:
• More repetition is required
• Time consuming
• Not efficient to finding true optimum
• Expensive to use.
13. • Example: In this example, A formulator can change the concentration
of binder and get the desired hardness.
14. A simplex is a geometric figure, defined by no. of points or
vertices equal to one more than no. of factors examined.
Once the shape of a simplex has been determined, the
method can employ a simplex of fixed size or of variable
sizes that are determined by comparing the magnitudes of
the responses after each successive calculation
15. • This method will find the true optimum of a response with
fewer trials than the non-systematic approaches or the one-
variable-at-a-time method.
Limitations :
• There are sets of rules for the selection of the sequential
vertices in the procedure.
• Requires mathematical knowledge.
16. o It represents mathematical techniques.
o It is an extension of classic method.
o applied to a pharmaceutical formulation and processing.
o This technique require that the experimentation be completed
before
optimization so that the mathematical models can be generates
17. oUnlike the Lagrangian method, do not require differentiability
of the objective function.
oIt is defined by appropriate equations.
oUsed for more than two independent variables.
oThe response surface is searched by various methods to find the
combination of independent variables yielding an optimum.
oIt take five independent variables into account and is computer
assisted.
oPersons unfamiliar with mathematics of optimization & with no
previous computer experience could carryout an optimization
study.
18. o Takes five independent variables in to account
o Person unfamiliar with the mathematics of optimization and
with no previous computer experience could carry out an
optimization study.
o It do not require continuity and differentiability of function
Disadvantage:
o One possible disadvantage of the procedure as it is set up is
that not all pharmaceutical responses will fit a second-order
regression model.
19. Provide solution to large scale manufacturing
problems.
Provides string assurances to regulatory agencies
superior drug product quality.
In microencapsulation process.
Improvement of physical & biological properties by
modification.
20. o Optimization techniques are a part of development process.
o The levels of variables for getting optimum response is
evaluated.
o Different optimization methods are used for different
optimization problems.
o Optimization helps in getting optimum product with
desired bioavailability criteria as well as mass production.
o More optimum the product = More the company earns in
profits !!!
