This presentation focuses on the entity known as pyrexia of unknown origin / fever of unknown origin. It demonstrates both common and rare causes, and the epidemiological trend, its clinical presentation, management and prognosis.
Exercise Testing in Cardiology : Dr. Akif Baigakifab93
The testing modality and protocol should be selected in accordance with the patient’s estimated functional capacity based on age, estimated physical fitness from the patient’s history, and underlying disease
Several exercise test protocols are available for both treadmill and stationary cycle ergometers
Patients who have low estimated fitness levels or are deemed to be at higher risk because of underlying disease (e.g., recent MI, heart failure) should be tested with a less aggressive exercise protocol
Treadmill and cycle ergometers may use stepped or continuous ramp protocols
Work rate increments (stages) during stepped protocols can vary from 1 to 2.5 METs
Ramp protocols are designed with stages that are no longer than 1 minute and for the patient to attain peak effort within 8 to 12 minutes
The natriuretic peptide system works antagonistically to the RAAS and has favorable effects on the pathogenesis of heart failure
Natriuretic peptides are broken down by an enzyme called neprilysin
Neprilysin is also responsible for the breakdown of other substances, including bradykinin and angiotensin II
Sacubitril/valsartan is a combination product
Sacubitril is a pro-drug that, upon activation, acts as a neprilysin inhibitor
It works by blocking the action of neprilysin, thus preventing the breakdown of natriuretic peptides
This leads to a prolonged duration of the favorable effects of these peptides
Coronary heart disease (CHD) remains a leading cause of death worldwide, accounting for 16% of total deaths globally .
Atherosclerosis plays a central role, with early fatty streaks progressing to late complex atheromas
Vascular calcification, the pathogenic and process of ectopic bone production, specifically was shown to strongly correlate with degree of atherosclerosis (both calcified and noncalcified)
Vascular calcification was shown independently to predict cardiovascular morbidity and mortality
These associations, combined with the radio-opaque appearance of calcium hydroxyappatite on CT images, have led to extensive investigation of the quantification, or scoring, of coronary artery calcium (CAC).
CAC scoring has emerged as a widely available and powerful tool for stratifying cardiovascular risk, predicting patient outcomes, and guiding preventive therapy
A coronary bifurcation consists of a flow divider (carina) and three vessel segments:
The proximal main vessel (PMV)
The distal main vessel (DMV) and
The side branch (SB).
A bifurcation lesion is a major epicardial coronary artery stenosis next to and/or including the ostium of a significant side branch
A significant SB is a branch whose severe narrowing or acute occlusion before or during intervention can cause considerable ischemia or a new infarction area that will worsen the clinical course of a particular patient.
Other important elements to consider that are not inherent in the bifurcation classifications include:
Extent of disease on the SB (limited to the ostium or involving the vessel beyond the ostium)
Its size (over 2.5mm in reference diameter)
Bifurcation angle, and
Disease distribution
Left ventricular (LV) dysfunction remains one of the
best prognostic determinants of survival in patients
with coronary artery disease (CAD)
⚫ It was originally thought that dysfunctional
myocardium after an infarction was irreversibly
damaged
⚫ However, it was later recognized that some of the
involved tissue remained viable and contractility may
be restored with revascularization
HCM is a common genetic heart disease reported in populations globally
Inherited in an autosomal dominant pattern
The distribution of HCM is equal by sex, although women are diagnosed less commonly than men
The prevalence of unexplained asymptomatic hypertrophy in young adults has been reported to range from 1:200 to 1:500
Tetralogy of Fallot (TOF) is a congenital heart defect, which has four anatomical components:
Anterior malalignment ventricular septal defect (VSD)
Aortic override over the muscular septum
Variable degrees of subvalvar, valvar, and supravalvar pulmonary stenosis
Right ventricular (RV) infundibular narrowing and RV hypertrophy
Ventricular septal defects occur either as an isolated defect or as a component of a more complex lesion
It occurs in 50 percent of all children with CHD and in 20 to 30 percent as an isolated lesion
Most common congenital cardiac anomaly in children
Second most common congenital abnormality in adults, second only to bicuspid aortic valves
They are more common in premature infants and those born with low weight
VSDs are slightly more common in females (56%)
Patients with peripheral artery disease who have undergone lower-extremity revascularization are at high risk for major adverse limb and cardiovascular events
The efficacy and safety of rivaroxaban in this context are uncertain
Most common cyanotic heart defect seen in children beyond infancy, accounting for a third of all congenital heart disease (CHD) in this age group
Tetralogy of Fallot (TOF) is a congenital heart defect, which has four anatomical components:
Anterior malalignment ventricular septal defect (VSD)
Aortic override over the muscular septum
Variable degrees of subvalvar, valvar, and supravalvar pulmonary stenosis
Right ventricular (RV) infundibular narrowing and RV hypertrophy
Bentracimab (also known as PB2452) is a neutralizing recombinant human immunoglobulin G1 monoclonal antibody antigen-binding fragment that binds ticagrelor and its major active circulating metabolite with high affinity and specificity
Chlorthalidone for hypertension in advanced ckdakifab93
Chlorthalidone, a thiazide-like diuretic, reduces cardiovascular morbidity, such as the incidence of stroke and heart failure, and cardiovascular mortality
However, its efficacy and safety among patients with advanced chronic kidney disease remain poorly understood
An acute illness caused by an autoimmune response to infection with group A Streptococcus, leading to a range of possible symptoms and signs affecting any or all of heart, joints, brain, skin and subcutaneous tissues
Amyloidosis is a group of protein-folding disorders in which >1 organ is infiltrated by proteinaceous deposits known as amyloid. Amyloid involvement of the heart (cardiac amyloidosis) carries the worst prognosis of any involved organ, and light-chain (AL) amyloidosis is the most serious form of the disease

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.
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

ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
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. -Fever >38.3*C (101*F) on atleast 2 occasions
- illness duration more than 3 weeks
-No known immunocompromised state
-Uncertain diagnosis despite one week of inpatient evaluation
3. Uncertain diagnosis despite one week of
inpatient evaluation Should include:
History and clinical examination
Complete blood count
Liver function test
Renal function test
Chest x ray
Ultrasound abdomen
ANA, CK, Ferritin, RA factor
Protein electrophoresis
Blood and urine cultures
- If all these tests doesn’t lead a doctor to a diagnosis, then it is
labelled as PUO
4. ETIOLOGY
1) Infections - most common
2) Malignancy
3) Autoimmune/ Connective tissue disorders
4) Other causes
In up to 20% of cases, cause of fever will not be identified despite
thorough workup
Temporal arteritis accounts for 16-17% of all causes of FUO in
the elderly
5.
6. INFECTIONS
-Most common infectious causes are:
Tuberculosis
Intrabdominal and pelvic Abscesses
-FUO in immunocompromised patients is often very difficult to diagnose
-Previously HIV was one of the most common cause but now its been
routinely tested
7. The most common malignancies are Hodgkin disease and
non-Hodgkin lymphoma.
MALIGNANCY
Diagnosis of malignancy or autoimmune disorders becomes
more likely as the duration of the fever increases.
8. Urgent Considerations
In PUO
Immunocompromised patients Giant cell arteritis suspect
Should be empirically treated
with broad spectrum
antibiotics till the time we get
a specific diagnosis
Should be treated with
Corticosteroids since if not
treated early may lead to
blindness.
