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.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
NVBDCP.pptx Nation vector borne disease control programSapna Thakur
NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
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.

18. EVALUATION OF CKD
• In people with GFR <60 ml/min/1.73m2
(GFRcategories G3a-G5)
• markers of kidney damage
• review past history
• previous measurements to determine
duration of kidney disease
• duration is >3 months
• CKD IS CONFIRMED
19. EVALUATION OF CKD
• urinalysis to detect hematuria or pyuria ,
urine microscopy to detect RBC casts or
WBC casts.
• Ultrasound to assess kidney structure for
kidney shape,size, symmetry and
evidence of obstruction
• Serum and urine electrolytes to assess
renal tubular disorders

22. DEFINITION AND IDENTIFICATION
OF CKD
PROGRESSION
• Define CKD progression based on one of
more of the following
• drop in GFR category accompanied by a
25% or greater drop in eGFR from
baseline
• Rapid progression is defined as a
sustained decline in eGFR of more than
5 ml/min/1.73 m2/year
• confidence in assessing progression is
increased with increasing number of
serum creatinine measurements and
duration of follow-up.
23. FOLLOWUP
• Assess GFR and albuminuria at least
annually in people with CKD. Assess GFR
and albuminuria more often for individuals
at higher risk of progression
• The AER is one of the best indicators of
diabetic nephropathy risk in both type 1
and type 2 diabetes
26. PREVENTION OF CKD PROGRESSION
• BLOOD PRESSURE
• diabetic and non diabetic adults with
CKD and urine albumin excretion <
30mg/24 hours treated with BP-
lowering drugs to maintain a BP that is
consistently<140mm and diastolic <90.
• CKD and with urine albumin excretion of
>30mg/24 hours maintain a BP
<130/80mmhg
27. • Use of ARB or ACE-I in both diabetic and
non-diabetic adults with CKD and urine
albumin excretion >300 mg/24 hours
• If diabetic, albuminuria 30-300mg /24 hrs
is indicated for ACE/ARBI
• electrolyte disorders, acute deterioration in
kidney function, orthostatic hypotension
and drug side effects has be given close
attention in CKD to prevent adverse effects
of antihypertensive therapy.
28. CKD and risk of AKI
• All CKD patients are at risk for AKI
• All reversible precipitating factors has to
be avoided
29. Protein intake in CKD
• protein intake restriction to 0.8
g/kg/day in adults with diabetes or
without diabetes and GFR <30 ml/min/
1.73 m2.
• avoid high protein intake (1.3 g/kg/day)
in adults with CKD at risk of progression
30. Diabetic control
• Glycemic control improves outcomes in people
with diabetes with or without CKD
• In people with CKD and diabetes, glycemic
control should be part of a multifactorial
intervention
• Blood pressure control and cardiovascular risk,
ACE-I,ARBS,Statins and antiplatelet therapy to
be used where clinically indicated
• Recommended target (HbA1c)at 7.0% and not
less to prevent hypoglycaemia and to delay
progression of the microvascular complications
of diabetes, including diabetic kidney disease
31. Salt intake
• Salt lowering intake to <2 g per day of
sodium (corresponding to 5 g of sodium
chloride) in adults, unless
contraindicated.
32. • Individuals with CKD should receive
expert dietary advice and information as
a education program, based on severity
of CKD and the need to intervene on
salt,phosphate, potassium, and protein
intake where indicated.
33. • Patients with CKD be encouraged to
undertake physical activity compatible
with cardiovascular health and tolerance
(aiming for at least 30minutes 5 times
per week),
• BMI - 20 to 25, and
• Stop smoking
34. COMPLICATIONS ASSOCIATED WITH LOSS OF KIDNEY
FUNCTION
• CKD are prone to develop a variety of complications which
reflect loss of endocrine or exocrine function of the kidney.
35. Anaemia
Diagnose anemia in adults and children >15 years
when the Hb concentration is
• <13.0 g/dl in males
• <12.0 g/dl in females.
Blood Hb monitoring in CKD
• when clinically indicated in people with GFR
>60 ml/min/1.73 m2
• at least annually in people with GFR 30-59 ml/min/1.73 m2
• at least twice per year in people with GFR<30 ml/min/1.73
m2
36. Anaemia (Cont)
• Work-up for anemia in CKD
• Iron replacement therapy if indicated
• ESA therapy is not recommended in those
with active malignancy
• ESAs should not be used to increase the
Hb concentration above 11.5g/dl
37. CKD METABOLIC BONE DISEASE
• Changes in bone mineral metabolism and
alterations in calcium and phosphate
homeostasis occur early in the course of CKD
and progress as kidney function decline
• serum levels of calcium,phosphate, PTH, and
alkaline phosphatase activity at least once in
adults with GFR o45 ml/min/1.73 m2.
• Aluminium hydroxide, Calcium citrate,
Magnesium carbonate,calcium acetate phosphrus
binders are used
38. Vit D hypovitaminosois
• As CKD progresses, levels of 1,25(OH)2D
progressively fall
• Deficiency of 25(OH)D increases fracture
risk and is associated with increased
mortality
• In vitamin D-deficient subjects
supplementation with vitamin D increases
BMD and muscle strength, reduces risk for
fractures reduces, and reduces PTH.
39. Acidosis
• Severity of metabolic acidosis in people with
CKD progressively rises as GFR falls.
• Chronic metabolic acidosis is associated with
increased protein catabolism, uremic bone
disease, muscle wasting, chronic
inflammation, impaired glucose homeostasis,
impaired cardiac function, progression of CKD,
and increased mortality
• In CKD with serum bicarbonate
concentrations <22 mmol/l ,oral bicarbonate
supplementation be given to maintain serum
bicarbonate within the normal range
40. Cardiovascular disease
• Heart Outcomes Prevention
• Evaluation (HOPE) study demonstrated
that any degree of albuminuria is a risk
factor for cardiovascular events in
individuals with or without diabetes
41. • 1. Smoking cessation
• 2. Exercise
• 3. Weight reduction to optimal targets
• 4. Lipid modification recognizing that the risk reduction
associated with statin therapy in adults with CKD
• 5. Optimal diabetes control HbA1C o7% (53 mmol/mol)
• 6. Optimal BP control to o140/90 mm Hg or o130/80

more of the following are
present:
• serositis, pericarditis
• acidbase or electrolyte
abnormalities
• Pruritus
• Inability to control volume
status or blood pressure
• a progressive deterioration in
nutritional status refractory to
dietary intervention

46. TIMING THE
INITIATION OF RRT
• Living donor preemptive
renal transplantation in
adults

m2,
• evidence of progressive
and irreversible CKD over
the preceding 6-12 months
This figure represents the current conceptual model of CKD and the continuum of development, progression, and complications of CKD and strategies to improve outcomes. Horizontal arrows between circles represent development, progression, and remission of CKD. Left-pointing horizontal arrowheads signify that remission is less frequent than progression. Diagonal arrows represent occurrence of complications of CKD, including drug toxicity, endocrine and metabolic complications, cardiovascular disease, and others such as infection, cognitive impairment, and frailty. Complications might also arise from adverse effects of interventions to prevent or treat the disease.
For most clinical circumstances, estimating GFR from serum creatinine (SCr) is appropriate for diagnosis, staging, and tracking the progression of CKD. However, like all diagnostic tests, interpretation is influenced by varying test characteristics in selected clinical circumstances and the prior probability of disease. In particular, an isolated decreased eGFR in otherwise healthy individuals is more likely to be a false positive than in individuals with risk factors for kidney disease or markers of kidney damage. Confirmation of decreased eGFR by measurement of an alternative endogenous filtration marker (cystatin C) or a clearance measurement is warranted in specific circumstances when GFR estimates based on SCr are thought to be inaccurate and when decisions depend on more accurate knowledge of GFR, such as confirming a diagnosis of CKD, determining eligibility for kidney donation, or adjusting dosage of toxic drugs that are excreted by the kidneys.
Pediatric considerations:
The use of SCr and recently derived pediatric specific GFR estimating equations, which incorporate a height term, are preferred over the use of SCr alone in the initial assessment of pediatric renal function (see KDIGO 2012 CKD Guideline, Reference Keys on p. ix)
For adults:
Use the following measurements for initial testing of proteinuria (in descending order of preference, in all cases an early morning urine sample is preferred):
urine albumin-to-creatinine ratio (ACR);
urine protein-to-creatinine ratio (PCR);
reagent strip urinalysis for total protein with automated reading;
reagent strip urinalysis for total protein with manual reading.
Urine albumin measurement provides a more specific and sensitive measure of changes in glomerular permeability than urinary total protein. There is substantial evidence linking increased albuminuria to outcomes of CKD and there is also evidence that urinary albumin is a more sensitive test to enable detection of glomerular pathology associated with some other systemic diseases including diabetes, hypertension and systemic sclerosis.
For children:
Use the following measurements for initial testing of proteinuria in children (in descending order of preference):
urine PCR, early morning urine sample preferred;
urine ACR, early morning urine sample preferred;
reagent strip urinalysis for total protein with automated reading;
reagent strip urinalysis for total protein with manual reading.
Currently urinary PCR should be favored over urine ACR in children. Unlike in adults where powerful evidence exists in support of the use of measures of albumin rather than total protein to predict adverse outcomes, this level of evidence is currently lacking in children.
For all CKD complications, prognosis will vary depending on: 1) cause; 2) GFR; 3) degree of albuminuria; and 4) other comorbid conditions.
Risk for kidney disease endpoints, such as kidney failure and AKI, is predominately driven by an individual patient’s clinical diagnosis, GFR, and the degree of albuminuria or other markers of kidney damage and injury.
For cardiovascular disease, risk will be determined by history of cardiovascular disease and traditional and non-traditional cardiovascular disease risk factors.
For other conditions, the risk will be determined by risk factors specific for those conditions.
For all conditions, the cause of CKD, GFR category and albuminuria category will still have important influence as “risk multipliers,” but will have smaller overall influence on disease prediction than risk factors specific for the condition. All these conditions have an impact on life expectancy and quality of life and contribute substantially to predicting the prognosis of CKD.
Pediatric considerations:
The rationale and principles behind this statement would apply to pediatrics though the data are not available.
For all CKD complications, prognosis will vary depending on:
Cause of CKD;
GFR category;
Albuminuria category;
Other risk factors and comorbid conditions.
The risk associations of GFR and albuminuria categories appear to be largely independent of one another. Therefore, neither the category of GFR nor the category of albuminuria alone can fully capture the prognosis for a patient with CKD.
All of the parameters above have an impact on life expectancy and quality of life and contribute substantially to predicting the prognosis of CKD.
Key to color grid:
Colors indicate groups of patients at higher risk of major outcomes:
Green represents low risk. If the patient does not have other markers of kidney disease, then CKD is not diagnosed or confirmed.
Compared with the Green box (eGFR>60 ml/min/1.73 m2 and ACR<30 mg/g [<3 mg/mmol]):
Yellow = is one step away from normal down or across. It represents moderately increased risk.
Orange = is two steps away from normal: down two, across two, or down one/across one. It represents high risk.
Red = is three steps away from normal. It represents very high risk.
General parameters to monitoring people with CKD:
Assess GFR and albuminuria at least annually in people with CKD.
Assess GFR and albuminuria more often for individuals at higher risk of progression, and/or where measurement will impact therapeutic decisions.
More frequent measures of eGFR and albuminuria should be considered in patients with a lower GFR and greater albuminuria as these people are more likely to progress. Frequency of measurement should also be individualized based on the patient history and underlying cause of kidney disease.
Recognize that:
Regular monitoring of stable patients may include more frequent monitoring than annually, but will be dictated by underlying cause, history, and estimates of GFR and ACR values obtained previously.
Small fluctuations in GFR are common and are not necessarily indicative of progression.
CKD progression is defined based on one of more of the following:
Decline in GFR category (≥90, 60–89, 45–59, 30–44, 15–29, <15 ml/min/1.73 m2). A certain drop in eGFR is defined as a drop in GFR category accompanied by a 25% or greater drop in eGFR from baseline.
Rapid progression is defined as a sustained decline in eGFR of more than 5 ml/min/1.73 m2/yr.
The confidence in assessing progression is increased with increasing number of serum creatinine measurements and duration of follow-up.
Note: These are general parameters only based on expert opinion and must take into account underlying comorbid conditions and disease state, as well as the likelihood of impacting a change in management for any individual patient. Not all individuals with CKD require close surveillance and monitoring; clinical context remains an important modifier for all recommendations.
