PETALING JAYA: More than 3,000 crime hotspots will be watched by police during patrols for the upcoming Hari Raya celebrations, says Bukit Aman.

The balik kampung holiday exodus, which begins this weekend, will also see the deployment of more than 6,000 personnel from the Crime Prevention and Community Safety Department (JPJKK) throughout the duration of Op Selamat, from March 29 to April 3.

Speaking to The Star, Bukit Aman JPJKK director Comm Datuk Wan Hassan Wan Ahmad said 3,148 crime prevention hotspots had been identified across the country.

“These hotspots are identified based on reports received by the police regarding crimes involving property and violence and have been studied by the JPJKK chiefs at the state and district levels,” he said.

Selangor tops the number of hotspots with 764, followed by Kuala Lumpur with 446.

Comm Wan Hassan said JPJKK would focus on efforts to reduce property crime rates such as burglary cases throughout the period of Op Selamat.

“To achieve this objective, the elements within JPJKK that will be fully mobilised are the Mobile Patrol Vehicle (MPV) and Motorcycle Patrol Unit (URB) elements.

“This will involve more frequent patrols in residential areas and high-risk locations,” he said.

A total of 2,670 patrol cars and 1,800 URB motorcycles along with 6,543 personnel from MPV and URB will be deployed for patrol duties through this festive season.

“Patrols will be conducted 24 hours in shifts, covering 1,129 patrol areas,” he said, adding that leave had been frozen and would only be granted for emergency cases.

Police statistics show that there was a slight increase in burglary cases during the Raya period last year compared to previous years.

There was a total of 190 burglary and theft cases in 2024 compared to 166 in 2023 and 172 in 2022.

Comm Wan Hassan said crime prevention patrols during the festive season and Op Selamat will also focus on homes that have been left vacant by residents returning to their hometowns, where residents have made movement reports at nearby police stations or through online reports using the Volunteer Smartphone app.

“Based on the information received, frontline personnel will carry out more frequent patrols at these places,” he said.

“Checks show that most of these burglary cases involve homes or premises whose occupants had not reported their return to their hometown to the police.”

Additional patrols will also be conducted by other elements within the police force, including patrols at the police station levels.

Comm Wan Hassan advised those who are not returning to their hometowns to report suspicious activities to the police.

Meanwhile, Deputy Inspector-General of Police Datuk Seri Ayob Khan Mydin Pitchay said Bukit Aman had identified 432 congestion hotspots and 122 accident blackspots nationwide.

For highways and expressways, police found hotspots and 46 blackspots, while federal, state and city roads contained 407 hotspots and 76 blackspots.

“Traffic Investigation and Enforcement Department (JSPT) personnel will be on hand to monitor the situation continuously and provide assistance in case of emergencies or vehicle breakdowns.

“The presence of JSPT personnel is aimed at facilitating traffic if a major congestion occurs.

“Stern action will also be taken against any traffic offenders.”

“Close to 7,000 JSPT personnel will be on duty for this year’s Ops Selamat.

“We advise the public to abide by traffic regulations and drive or ride safely.

“Road users must also ensure their vehicles are at optimum level and get enough sleep and rest before beginning their journeys,” he said.

Learn about your urine – it tells you more about your health than you think

Your urine can tell you several things about your diet and health even without a test. — 123rf

Go ahead, get the giggles out of the way; we’re about to take a close look at urine, and in such conversations, bathroom humour is often the number one byproduct.

But once you’re through, perhaps you can also relieve yourself of the notion that urine is simply material for third-grade (primary school) punchlines – or even simple at all.

Urine is the result of a fascinating and complex system – of which the kidneys are the star – that evolved to keep our internal systems in balance, said University of Alabama at Birmingham cardio-renal physiology and medicine co-director and professor of medicine Dr David Pollock.

“It’s basically what keeps your cells alive,” he said.

“It maintains the internal environment of your entire body.”

Which makes understanding what’s in your pee important.

And that begins with understanding how it’s made.

Kidney control

Urine is created in the kidneys, whose job is usually described as filtering blood.

But the kidneys do much more than that, Prof Pollock said.

“There’s a very close relationship between the heart and the kidneys,” he said.

The kidneys control how much sodium and water your body retains.

That water equates to the volume of blood you carry, and the greater the volume, the higher the pressure will be.

And that makes the kidneys the primary organ in charge of blood pressure.

“And basically, the kidney is responsible for making sure that it doesn’t get too high,” said Prof Pollack.

The kidneys control that volume by regulating sodium.

When sodium is retained, blood volume goes up.

The kidneys also regulate potassium, which helps limit the effects of sodium.

Both are electrolytes, and the kidneys maintain electrolytes at “very, very precise concentrations,” said George Washington University School of Medicine and Health Sciences professor of medicine Dr Janani Rangaswami.

Those concentrations can significantly affect health, said the chief of nephrology at the Washington VA Medical Center.

Electrolyte imbalances such as low sodium levels, can lead to seizures.

High or very low potassium could lead to heart rhythm problems.

The kidneys also balance the blood’s acidity and filter out waste products, as well as some drugs, from the bloodstream.

The result of all this balancing and filtering is urine.

It flows from the kidneys through the ureters to the bladder, where it’s stored until the next commercial break, rest area or whenever it’s your turn in the bathroom.

Depending on a person’s size, the kidneys might filter around 48 gallons (181.7l) of blood each day, Prof Rangaswami said.

That might yield up to a couple of quarts (1.9l) of urine, although it’s important to not fixate on how much urine you produce, she said.

Patients sometimes get the mistaken notion that “if they don’t have a certain urine output, that’s a bad thing, which is not true,” she said.

In reality, the amount can be “all over the place”, varying because of how much fluid you’re drinking, the health of your kidneys and the medications you may be taking.

Urine composition

The exact composition of urine can vary day to day as well, she said.

But most of it – from 91% to 96% – is water.

Thousands of additional components have been identified in urine.

Prof Pollock and Prof Rangaswami say these are the most prominent ones:

> Urea

“Your body takes the protein that you eat, it breaks it down and takes energy from it, and then you have urea left over,” Prof Pollock said.

Urea is mostly nitrogen.

It makes a good fertiliser, and bacteria break it down into ammonia.

This made urine valuable in pre-industrial times for everything from tanning leather to cleaning laundry.

In ancient Rome, urine was collected from public toilets, and it was taxed.

Ammonia is what makes urine smell the way it does, Prof Pollock said.

> Electrolytes

In addition to sodium and potassium, electrolytes include chloride, magnesium and calcium.

Phosphorus, another electrolyte, is what causes urine to glow under ultraviolet light.

> Uric acid

This nitrogen-based compound is created when the body breaks down food and drinks that contain chemicals called purines.

Meats, seafood, beer, beans and some vegetables are high in purines.

Too much uric acid can lead to kidney stones or gout.

> Creatinine

This waste product is created as muscles work and as protein is digested.

A test called UACR, which stands for urine albumin-creatinine ratio, looks for albumin, a protein that can be a warning sign of kidney disease, Prof Rangaswami said.

That, along with blood tests that look at creatinine or urea nitrogen levels, can give doctors a good idea of current kidney function and future risk for worsening kidney function.

That’s important, she said, because “kidney disease is a powerful risk enhancer for cardiovascular disease”.

Observing your pee

Although urinalysis is as old as medicine itself – Sumerian and Babylonian physicians recorded their findings on clay tablets 6,000 years ago, and Sanskrit texts from 100 BC noted 20 types of urine – your urine can tell you several things even without a test.

Urine gets its yellow colour from a chemical called urobilin, or urochrome.

But the intensity of that colour can vary depending on how much water you’ve been drinking.

“A lot of patients wrongly infer that if their urine looks concentrated, or if it’s dark yellow, that something is wrong,” Prof Rangaswami said.

“That’s just a reflection of the urine being more concentrated.

“And usually, drinking more fluids will make it clear.

“So there is no reason to get concerned every time you notice a slight change in the colour.”

Certain foods, such as beets and asparagus, and some medications can also cause exotic, but harmless, changes in the colour or smell of urine, she said.

But “any blood that is visible in the urine should always prompt a medical evaluation,” Prof Rangaswami said.

And persistent foamy urine could be a sign of too much protein in the urine.

This would be a symptom to discuss with a doctor, she said, particularly for someone who is at risk for kidney disease.

That would include people with diabetes, obesity or high blood pressure.

Prof Rangaswami encourages people to make sure their healthcare team is performing routine UACR tests to monitor kidney health, and to follow a doctor’s advice if they have specific conditions such as kidney stones.

But for the most part, healthy urine flows naturally from healthy kidneys, and kidneys are kept healthy by the same habits that help the rest of the body.

“In terms of diet, what would generally be considered a heart-healthy diet is also a kidney-healthy diet,” she said.

That would include eating less sodium and more fresh fruits, vegetables and whole grains, while backing off on heavily-processed foods.

Overall, Prof Rangaswami said, a conversation about urine is a good way to put the importance of kidney health in focus.

And “anything we can do to protect and keep the kidneys healthy is going to be good for their heart as well”. – By Michael Merschel/American Heart Association News/Tribune

Malaysia to byte crime with AI

PETALING JAYA: Malaysia is among nations aiming to use artificial intelligence (AI) in investigating commercial crimes.

However, the Artificial Intelligence Society Malaysia has urged the police force to first guarantee that the men in blue receive thorough training.

Its president Dr Azree Shahrel Ahmad Nazri said police officers need to understand how AI tools function, interpret AI-generated insights correctly and ensure their investigations maintain human oversight.

“AI is only as effective as the people using it.
