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.

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

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!
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.
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

Enzymes, present throughout the body, are dependent on normal, physiologic temperature and pH for proper functioning
Common examples of enzymes include:
Liver transaminases – ALT and AST
Cardiac and muscle enzymes - CK-MM, CK-MB, CK-BB
and Coagulation Factors.
Catecholamines such as adrenaline, are also depend upon enzymes for proper functioning
pH is a measurement of how acidic or basic a substance is. The pH scale runs from 0 to 14. Zero is the most acidic, 14 is the most basic, 7 is neutral.
If there is excess acid, the environment is called acidic or acidotic. The most common acidic ions are hydrogen ions. If there is an excess of base, the environment is call basic or alkalotic. There are many basic ions in the body, but bicarbonate is very common. Too much acid in the blood is called acidemia. Too much base in the blood is called alkalemia. Normal physiologic pH in the human body is 7.35 – 7.45. If the pH is less than 7.35 there is an acidemia and if greater than 7.45 an alkalemia is present.
When the pH falls outside of this physiologic range, certain functions within cells and tissues may not work properly leading to organ dysfunction.
Within the body there are several buffering systems that work to keep the pH in physiologic range to ensure proper functioning of enzymes, cells and tissues. The two most important organs that function to regulate pH are the lungs and the kidneys. This occurs through the bicarbonate-carbon dioxide buffering system, a reversible reaction.
The respiratory system can increase or decrease the amount of carbon dioxide removed from the blood. Breathing quickly removes more CO2. Removing CO2 pulls the buffer equation to the left. Pulling the equation to the left decreases the amount of acidic hydrogen ions. This decreases acidosis and creates a more alkaline environment. Conversely, decreased respiratory rates or apnea lead to a retention of carbon dioxide. Increases in retained CO2 results in more hydrogen ions and a more acidotic state.
A physiologic process that leads to increasing acid is called an acidosis, whereas a process that leads to a more basic state is called an alkalosis. The lungs can create or compensate for acid and base states very quickly within minutes.
pH can also be regulated through the kidneys, which are capable of resorbing or excreting both hydrogen ions and bicarbonate. In a state of acidosis, the kidneys will work to retain bicarbonate and excrete hydrogen ions. In a state of alkalosis, the kidneys will work to excrete bicarbonate and retain hydrogen ions. In addition to the bicarbonate-carbon dioxide buffer system, the kidneys have other ways to excrete acid and hydrogen ions, called urine soluble acids. Examples include phosphoric acid and ammonium.
Unlike the minutes it takes for the respiratory system to respond to acid/base changes, the kidneys take hours to days.
In normal physiologic states, pH ranges from 7.35 to 7.45. The partial pressure of carbon dioxide in the blood ranges from 38-42mmHg. Bicarbonate ranges from 22-26 mEq/L. A pH less than 7.35 results in an acidemia and a pH greater than 7.45 results in an alkalemia.
Acidemia can occur from too little bicarbonate or too much carbon dioxide.
Alkalemia can occur from too little carbon dioxide or too much bicarbonate.
When the process is driven by carbon dioxide it is termed – “respiratory”. When the process is driven by bicarbonate, it is termed – “metabolic”. Therefore, it is possible to have a metabolic acidosis or a metabolic alkalosis. It is also possible to have a respiratory acidosis or a respiratory alkalosis. In many cases, it is possible to have a combination of acid/base disorders.
