Ketosis occurs when there is an excess of fatty acid metabolism due to inadequate carbohydrate intake or metabolism. This produces ketone bodies - acetone, acetoacetic acid and beta-hydroxybutyric acid - which are excreted in urine as ketonuria. Ketonuria is commonly seen in uncontrolled diabetes and other conditions involving excessive fat metabolism and limited carbohydrate availability. It can be detected using tests like Rothera's test, reagent strips, or nitroprusside tablets which detect ketone bodies in urine and produce a color change.
The Urine Culture Test is performed to detect and diagnose a microbial infection of the urinary tract.

Urine sugar testing was established as a clinical laboratory procedure during the 19th century. A glucose in urine test measures the amount of glucose in urine. Glucose is a type of sugar. It is our body’s main source of energy. A hormone called insulin helps move glucose from our bloodstream into our cells. If too much glucose gets into the blood, the extra glucose will be eliminated through our urine. A urine glucose test can be used to help determine if blood glucose levels are too high, which may be a sign of diabetes. If sugar levels remain high and don’t receive treatment, complications may develop and may have serious condition like type-I and type-II diabetes.
Si, it is an important test for detecting diabetes.
Albumin is a large molecule protein found in the blood, under normal circumstances it does not pass into the urine. If albumin occurs in the urine it could indicate infection of the urinary tract, kidney damage as in nephritis and toxemia in pregnancy. A urine for albumin test is a screening test to look for the presence of albumin in the urine .An albumin test cheeks urine for a protein called albumin for urine . Albumin is normally found in blood and filtered by kidneys. When the kidneys are working as the slow, there may be very small amount albumin in the urine .But when the kidneys are damage ,abnormal amounts of albumin leaks in the urine. This is called albuminuria.

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.

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. KETOSIS
Whenever there is a defect in carbohydrate metabolism or
absorption or an inadequate amount of carbohydrate in the diet,
the body compensates by metabolizing increasing amounts of
fatty acids.
When this is increase is large, ketone bodies the products of
incomplete fat metabolism , begin to appear in the blood known
as ketonemia and is followed by kenonuria and kussmaul
respiration (acetone breath).these all are collectively known as
ketosis.
3. KETONE BODIES
Ketones bodies are water soluble molecules produced by liver,
intermediate product of fat metabolism, they are acetone,
acetoacetic acid and beta hydroxybutyric acid.
Ketone is found when there is excessive fat metabolism.
excessive fat metabolism occurs in various situation
Impaired ability to metabolize carbohydrate
Inadequate carbohydrate intake
Excessive carbohydrate loss
Increased metabolic demand.
4. KETOGENESIS
Acetyl coA + Acetyl coA
acetoacetyl coA synthase
Acetoacetyl coA
HMG coA synthase
b-hydroxy b-methyl glutaryl coA
HMG coA lyase
Acetoacetate
decarboxylaton dehydrogenase
acetone b-hydroxy butyrate
5. KETONURIA
In ketonuria, the three ketone bodies present in the urine are
Acetoacetic (diaacetic) acid (20%)
Acetone (2%)
3-hydroxybutarate(about 78%)
According to killander (1962) up to 2mg acetoacetic acid per
deciliter is normal. Ketonemia and ketonuria are commonly seen in
uncontrolled diabetes mellites, as well as several other conditions.
6. DIABETIC KETONURIA
Ketonuria implies the presence of ketoacidosis (ketosis) and may
provide a warning of impending coma.
Upto 50mg of acetoacetic acid per deciliter may be present
without clinical evidence of ketosis.
Type 1 diabetic patients are prone to episodes of ketosis, often
associated with infection ,stress or other problems in
management.
Whereas there are large amounts of ketones and glucose in urine
in diabetic ketoacidosis, ketonuria is not found with the
hyperosmolar hyperglycemic coma sometimes occuring in type
2 diabetics.
7. NON DIABETIC KETONURIA
In infants and children, ketonuria commonly occurs in a variety
of condition, such as acute febrile diseases and toxic states
accompained by vomiting or diarrhoea.
Inherited metabolic disease should be suspected when there is
severe persistent neonatal ketosis. Ketonuria may be present in
hyperemesis of pregnancy, in cachexia, and following
anesthesia. In these case, ketoneuria is likely related to
increased tissue (especially fat) catabolism in the face of limited
food intake.
In pregnancy, a normal patient may have a low fasting blood
glucose level and mild ketonuria.
8. LACTIC ACIDOSIS
Lactic acidosis may coexist with many conditions including
shock diabetes mellitus, renal failure, liver disease , infections
and in response to certain drugs, especially phenformin and
salicylate poisoning.
Acetoacetate and 3-hydroxybutyrate may both be highly
elevated, although usually the butyrate is high and acetoacetate
low. Under these circumstances, ketonuria may not be detected
by usual nitroprusside test.
9. METHODS
Rothera's test for acetone.
Reagent strip test
Nitroprusside tablet test
Gerhard's test for diacetic acid
Lindeman's test for diacetic acid
Han’s method for beta-hydroxybutyric acid.
Enzymatic method
Flourometric technique and automatic colorimetric
method
10. ROTHERA’S TEST
Principle: Nitroprusside used in this test reacts with both acetone
and acetoacetic acid in presence of alkali to produce purple ring
at the junction.
Requirements
Test tubes
dropper
Rothera’s powder mixture
Sodium nitroprusside:1gm
Ammonium sulphate:20gm
Sodium carbonate:20gm
11. Procedure
Weigh out require amount of sodium nitropruside, ammonium
sulphate and anhydrous sodium carbonate.
Mix completely, but do not grind together. keep dry and it will
keep for at least a year.
Place a small pinch of powder on a white surface tile or in test
tube and add 1 drop of urine.
Acetone and acetoacetic acid give an immediate violet colour.
Report as trace, (+) , (2+), (3+) as the intensity of purple colour.
ROTHERA’S TEST
12. REAGENT STRIP TEST
This method is based on a
nitroprusside (sodium
nitroferricyanide) reaction for ketones.
Different formulations are available.
Reagent strips without alkali react to
acetoacetic acid and not to acetone.
With large (3+) results, urine may be
diluted and remeasured, reporting a
‘moderate’ result and dilution factor.
13. Chemstrip reagent strip contains sodium nitroferricyanide and
glycine, which react with acetoacetic acid and acetone in an
alkaline medium to form a violet dye. A positive result is
indicated by a colour change from beige to violet, which is
read at 60 seconds.
The method detects about 10mg/dl of acetoacetic acid and
70mg/dl of acetone, and the sensitivity and reaction of the
reagent strip are similar to those of the tablet.
Multistrip contains buffer and sodium nitroferricyanide,
which react with acetoacetic acid ,producing a pink maroon
color in 15 seconds.
The reagent area detects 5-10 mg acetoacetic acid per deciliter
of urine. It does not react with acetone.
REAGENT STRIP TEST
14. Disadvantages of reagent strip test
False positive occurs :
After use of phthaleins(BSP or PSP dyes) or in the
presence of extremely large amounts of phenylketones
and the preservatives 8-hydroxyquinoline or 1-dopa
metabolites.
Acetylcysteine(aerosol) produces a strong red color.
Antihypertensive drugs methyldopa and captopril give
positive results.
False negative results occur :
loss of reagent reactivity
Presence of salicylates
REAGENT STRIP TEST
15. NITROPRUSSIDE TABLET TEST
A tablet test method may be useful if the urine has interfering color.
These are very sensitive to humidity and will deteriorate if not stored
properly.
The acetest tablet contains sodium nitroprusside, glycine, and a
strongly alkaline buffer.
It can be used to assay whole blood, plasma, serum or urine.
Acetest will detect 5-10 mg of acetoacetic acid per deciliter of urine
and 20-25mg acetone per deciliter of urine. Like the reagent strip, it
does not react with 3-hydroxybutyrate.
It will give positive results with 1-dopa and large amount of
phenylketones and with BSP and PSP dyes, which react with the
alkali in tablets.
16. Procedure for tablet test
Place the tablet on a clean surface, preferbly a piece of white
paper.
Place one drop of urine, serum, plasma or whole blood on the
tablet
For urine measurement, compare the color of the tablet with a
color chart at 30 seconds.
For serum or plasma measurement, compare color of tablet
with color chart at 2 minutes.
For whole blood measurements, remove clotted blood from
tablet and compare color of tablet with color chart, 10 minutes
after application of the specimen.
17. If acetone and acetoacetic acid are present , the tablet will
show a color varying from lavender to deep purple.
Report the result as negative, small , moderate, or large.
If large , a dilution may be made. Report these analyses in
a form such as this undiluted “large” 1:2 dilution “large”
1:4 dilution “ moderate” etc.
