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.

Muktapishti is a traditional Ayurvedic preparation made from Shoditha Mukta (Purified Pearl), is believed to help regulate thyroid function and reduce symptoms of hyperthyroidism due to its cooling and balancing properties. Clinical evidence on its efficacy remains limited, necessitating further research to validate its therapeutic benefits.
Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...Oleg Kshivets
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
2. LEARNING OBJECTIVES
By the end of this lecture the reader
should be able to:
To know the different methods for
assessing the nutritional status
To understand the basic
anthropometric techniques,
applications, & reference standards
3. INTRODUCTION
The nutritional status of an individual
is often the result of many inter-
related factors.
It is influenced by food intake,
quantity & quality, & physical health.
The spectrum of nutritional status
spread from obesity to severe
malnutrition
4. Nutritional Assessment Why?
The purpose of nutritional assessment is
to:
Identify individuals or population groups
at risk of becoming malnourished
Identify individuals or population groups
who are malnourished
5. Nutritional Assessment Why? 2
To develop health care programs that
meet the community needs which are
defined by the assessment
To measure the effectiveness of the
nutritional programs & intervention
once initiated
6. Methods of Nutritional Assessment
Nutrition is assessed by two types of
methods; direct and indirect.
The direct methods deal with the
individual and measure objective
criteria, while indirect methods use
community health indices that
reflects nutritional influences.
7. Direct Methods of Nutritional
Assessment
These are summarized as ABCD
Anthropometric methods
Biochemical, laboratory methods
Clinical methods
Dietary evaluation methods
8. Indirect Methods of Nutritional
Assessment
These include three categories:
Ecological variables including crop
production
Economic factors e.g. per capita
income, population density & social
habits
Vital health statistics particularly
infant & under 5 mortality & fertility
index
9. CLINICAL ASSESSMENT
It is an essential features of all
nutritional surveys
It is the simplest & most practical
method of ascertaining the nutritional
status of a group of individuals
It utilizes a number of physical signs,
(specific & non specific), that are
known to be associated with
malnutrition and deficiency of vitamins
& micronutrients.
10. CLINICAL ASSESSMENT/2
Good nutritional history should be
obtained
General clinical examination, with
special attention to organs like hair,
angles of the mouth, gums, nails,
skin, eyes, tongue, muscles, bones,
& thyroid gland.
Detection of relevant signs helps in
establishing the nutritional diagnosis
12. Clinical signs of nutritional deficiency
HAIR
Protein, zinc, biotin
deficiency
Spare & thin

deficiency
Corkscrew
Coiled hair
14. Clinical signs of nutritional deficiency

Pigmentation,
desquamation
Vit K ,Vit C & folic acid
Bruising, purpura
17. Clinical signs of nutritional deficiency
Thyroid gland
in mountainous
areas and far from
sea places Goiter is
a reliable sign of
iodine deficiency.
18. Clinical signs of nutritional deficiency
Joints & bones
Help detect signs of
vitamin D
deficiency (Rickets)
& vitamin C
deficiency (Scurvy)
19. Anthropometric Methods
Anthropometry is the measurement of
body height, weight & proportions.
It is an essential component of clinical
examination of infants, children &
pregnant women.
It is used to evaluate both under &
over nutrition.
The measured values reflects the
current nutritional status & don’t
differentiate between acute & chronic
changes .
21. Anthropometry for children
Accurate measurement of height and
weight is essential. The results can
then be used to evaluate the physical
growth of the child.
For growth monitoring the data are
plotted on growth charts over a period
of time that is enough to calculate
growth velocity, which can then be
compared to international standards
23. Measurements for adults
Height:
The subject stands erect & bare
footed on a stadiometer with a
movable head piece. The head
piece is leveled with skull vault
& height is recorded to the
nearest 0.5 cm.
24. WEIGHT MEASUREMENT
Use a regularly calibrated electronic
or balanced-beam scale. Spring
scales are less reliable.
Weigh in light clothes, no shoes
Read to the nearest 100 gm (0.1kg)
25. Nutritional Indices in Adults
The international standard for assessing
body size in adults is the body mass index
(BMI).
BMI is computed using the following
formula: BMI = Weight (kg)/ Height (m²)
Evidence shows that high BMI (obesity level)
is associated with type 2 diabetes & high risk
of cardiovascular morbidity & mortality
27. Waist/Hip Ratio
Waist circumference is measured
at the level of the umbilicus to
the nearest 0.5 cm.
The subject stands erect with
relaxed abdominal muscles, arms
at the side, and feet together.
The measurement should be
taken at the end of a normal
expiration.
28. Waist circumference
Waist circumference predicts mortality better
than any other anthropometric
measurement.
It has been proposed that waist
measurement alone can be used to assess
obesity, and two levels of risk have been
identified
MALES FEMALE
LEVEL 1 > 94cm > 80cm
LEVEL2 > 102cm > 88cm
29. Waist circumference/2
Level 1 is the maximum acceptable
waist circumference irrespective of
the adult age and there should be no
further weight gain.
Level 2 denotes obesity and requires
weight management to reduce the
risk of type 2 diabetes & CVS
complications.
30. Hip Circumference
Is measured at the point of greatest
circumference around hips & buttocks to
the nearest 0.5 cm.
The subject should be standing and the
measurer should squat beside him.
Both measurement should taken with a
flexible, non-stretchable tape in close
contact with the skin, but without
indenting the soft tissue.
31. Interpretation of WHR
High risk WHR= >0.80 for females &
>0.95 for males i.e. waist
measurement >80% of hip
measurement for women and >95%
for men indicates central (upper
body) obesity and is considered high
risk for diabetes & CVS disorders.
A WHR below these cut-off levels is
considered low risk.
32. ADVANTAGES OF ANTHROPOMETRY
Objective with high specificity &
sensitivity
Measures many variables of nutritional
significance (Ht, Wt, MAC, HC, skin fold
thickness, waist & hip ratio & BMI).
Readings are numerical & gradable on
standard growth charts
Readings are reproducible.
Non-expensive & need minimal training
33. Limitations of Anthropometry
Inter-observers errors in
measurement
Limited nutritional diagnosis
Problems with reference standards,
i.e. local versus international
standards.
Arbitrary statistical cut-off levels for
what considered as abnormal values.
34. DIETARY ASSESSMENT
Nutritional intake of humans is
assessed by five different methods.
These are:
24 hours dietary recall
Food frequency questionnaire
Dietary history since early life
Food dairy technique
Observed food consumption
35. 24 Hours Dietary Recall
A trained interviewer asks the
subject to recall all food & drink
taken in the previous 24 hours.
It is quick, easy, & depends on short-
term memory, but may not be truly
representative of the person’s usual
intake
36. Food Frequency Questionnaire
In this method the subject is given a
list of around 100 food items to
indicate his or her intake (frequency &
quantity) per day, per week & per
month.
inexpensive, more representative &
easy to use.
37. Food Frequency Questionnaire/2
Limitations:
long Questionnaire
Errors with estimating serving size.
Needs updating with new commercial
food products to keep pace with
changing dietary habits.
38. DIETARY HISTORY
It is an accurate method for
assessing the nutritional status.
The information should be collected
by a trained interviewer.
Details about usual intake, types,
amount, frequency & timing needs
to be obtained.
Cross-checking to verify data is
important.
39. FOOD DAIRY
Food intake (types & amounts)
should be recorded by the subject at
the time of consumption.
The length of the collection period
range between 1-7 days.
Reliable but difficult to maintain.
40. Observed Food Consumption
The most unused method in clinical practice,
but it is recommended for research purposes.
The meal eaten by the individual is weighed
and contents are exactly calculated.
The method is characterized by having a high
degree of accuracy but expensive & needs time
& efforts.
41. Interpretation of Dietary Data
1. Qualitative Method
using the food pyramid & the basic
food groups method.
Different nutrients are classified
into 5 groups (fat & oils, bread &
cereals, milk products, meat-fish-
poultry, vegetables & fruits)
determine the number of serving
from each group & compare it with
minimum requirement.
42. Interpretation of Dietary Data/2
2. Quantitative Method
The amount of energy & specific nutrients
in each food consumed can be calculated
using food composition tables & then
compare it with the recommended daily
intake.
Evaluation by this method is expensive &
time consuming, unless computing facilities
are available.
43. Initial Laboratory Assessment
Hemoglobin estimation is the most
important test, & useful index of the
overall state of nutrition. Beside
anemia it also tells about protein &
trace element nutrition.
Stool examination for the presence of
ova and/or intestinal parasites
Urine dipstick & microscopy for
albumin, sugar and blood
44. Specific Lab Tests
Measurement of individual nutrient
in body fluids (e.g. serum retinol,
serum iron, urinary iodine, vitamin
D)
Detection of abnormal amount of
metabolites in the urine (e.g. urinary
creatinine/hydroxyproline ratio)
Analysis of hair, nails & skin for
micro-nutrients.
45. Advantages of Biochemical Method
It is useful in detecting early changes
in body metabolism & nutrition before
the appearance of overt clinical signs.
It is precise, accurate and
reproducible.
Useful to validate data obtained from
dietary methods e.g. comparing salt
intake with 24-hour urinary excretion.
46. Limitations of Biochemical Method
Time consuming
Expensive
They cannot be applied on large scale
Needs trained personnel & facilities
