Swatting flies could help in stroke rehab

 Your competent? doctor already has you stomping cockroaches for your lower limbs and balance ,right?

I like the cockroach stomping game

Or this interactive carpet: Interactive carpet for stroke rehab

NO, So, PURE INCOMPETENCE!

Swatting flies could help in stroke rehab

Researchers at the US-based University of Central Florida (UCF) are working on a software program that will immerse stroke survivors in a virtual world – full of flying insects – to help patients expand their range of movement.

The virtual game would require users to put on goggles while sitting at a table. A few bugs would fly around nearby, which the patients would have to smash.

Each time they succeed, they would earn a point. As patients improve their range of motion, more bugs would appear at greater distances, forcing patients to work harder and increase their range of motion.

“It has to be fun so patients will actually do their physical therapy exercises,” said Eileen Smith, associate director of UCF’s Media Convergence Lab (MCL) at the Institute of Simulation and Training.

To create the software that can also track the user’s progress, MCL teamed up with the Virtual Reality Medical Centre (VRMC) in California.

“One of the sad things about stroke is that it is very isolating,” Smith said.

“If we can make the game fun for everyone, then maybe grandchildren will jump in while grandma is doing her exercises. Then it won’t just be a physical therapy session; it will be family time. It will help patients re-engage.”

She is collaborating with the project’s lead researcher, Charles Hughes, director of the Media Convergence Lab and a professor in UCF’s School of Electrical Engineering and Computer Science.

During preliminary work, the researchers produced a viable program to track the patients’ progress.

The team is working with a doctor and a physical therapist along with VRMC to create the prototype.

VRMC plans to introduce the fully functional program to physical therapy clinics by 2009.

Mark Wiederhold, VRMC’s president, said the company would eventually market the product as a take-home program that patients could run on their computers or hand-held devices.

“The project goes with our lab’s philosophy,” Smith said.  “We don’t want to create cool widgets. We want to create things people can actually use to better their lives.”

Chronic stress linked to heart damage, other risks in new imaging study

 

Don't let your incompetent? doctor stress you out by NOT HAVING EXACT 100% RECOVERY PROTOCOLS! You doctor has known of this fucking failure since medical school and DONE NOTHING! THAT IS PURE INCOMPETENCE! Get that doctor fired!

Chronic stress linked to heart damage, other risks in new imaging study

Chronic stress is associated with an increased risk of heart damage, according to new data published in the European Journal of Preventive Cardiology.[1] The same study linked living a stressful life to a significantly higher risk of experiencing a heart attack or stroke.

Researchers tracked data from more than 480,000 U.K. Biobank participants, using cardiac MRI scans to identify signs of chronic inflammation. The group then used artificial intelligence to learn more about how such inflammation impacts the heart and impacts a person risk of experiencing a major adverse cardiovascular event (MACE).

Overall, the group found that larger amounts of chronic inflammation—a low-level activation of a person’s immune system—were linked to reduced left ventricular volumes and an increased MACE risk. 

“Our study, which is the largest of its kind, suggests that millions of people could be living with hidden inflammation, which is slowly changing their heart and causing long-term damage—increasing the risk of heart attack and stroke,” corresponding author Declan O’Regan, PhD, a researcher with the MRC Laboratory of Medical Sciences and Imperial College London, explained in a statement. “Chronic inflammation is complicated, but we know it’s tied to our health and driven by a range of lifestyle and economic factors—meaning people may be at more risk just because of their surroundings, their economic status, their family’s health and their lifestyle.”

Chronic inflammation has previously been linked to an increased risk of diabetes and certain cancers. O’Regan noted that a large number of things can contribute to chronic inflammation, including everything from smoking and inactivity, to a person’s genetics.

Bryan Williams, chief scientific officer and chief medical officer of the British Heart Foundation, was not involved in this analysis, but he provided his own perspective in the same statement.

“The research provides valuable insights into how our genes and lifestyle factors, such as smoking, poor mental health and socioeconomic status, can converge to trigger inflammation,” he said. “It also identifies several inflammatory proteins that appear to play a key role in the heart changes linked to chronic inflammation, and it is to be hoped that anti-inflammatory medicines could become an important tool in preventing cardiovascular disease.”

Research teams all over the world have been hard working to develop new ways to reduce inflammation as a way to potentially improve cardiovascular outcomes. These findings help make the case that such studies could be potential game-changers in the years ahead.

This is exactly how much vitamin D3 you should be taking every day

 Your competent? doctor and dietician have already given you EXACT PROTOCOLS on vitamins, right? 

Oh No; INCOMPETENCE REIGNED AND NOTHING WAS DONE!

This is exactly how much vitamin D3 you should be taking every day

Nancy Rodriguez, PhD, RDN, FACSM, a professor of nutritional sciences at the University of Connecticut, says that back in her day, no one was talking about vitamin D supplements. “In the ‘60s and ‘70s, people weren’t slathering on sunscreen. We were basking in the sun with baby oil,” she says.

Though such intense sun worship had its own issues (like increasing the risk of skin cancer), it also meant that vitamin D deficiencies among the general population were rare. But these days, most of us work desk jobs and when we do go outside, we slather on sunscreen. While this is great for lowering the risk of skin cancer, it also means that we’ve become a nation of vitamin D-deficient people. According to a 2022 study published in Frontiers in Nutrition, 41% of people in the U.S. don’t get enough vitamin D.

Our bodies need vitamin D. The nutrient is responsible for more than 200 functions in the body, including bone strength, dopamine production (key for feeling happy), brain health, and immune support. While getting enough vitamin D is important, it’s also important not to take too much in supplement form, which is dangerous. That can make shopping for the perfect vitamin D supplement tricky. Curious about how much vitamin D3 you should take daily? Here’s everything you need to know.

What's the difference between vitamin D2 and vitamin D3?

Like all nutrients, Allison Miner, EdD, RDN, a registered dietitian and assistant professor of nutrition and food studies at George Mason University, says the best way to get vitamin D isn’t in supplement form; it’s through food and, in this case, the sun. She says that foods with vitamin D include fatty fish, egg yolks, and fortified cereals, orange juice, and milk. Also, apparently, beef liver.

Sina Gallo, PhD, RD, a registered dietitian and nutritional sciences associate professor at the University of Georgia, explains that fatty fish, egg yolks, and beef liver all contain vitamin D3 while fortified foods contain both.

“Some research has suggested D3 can raise and maintain blood vitamin D levels more effectively and for longer than D2, although if taken daily they likely act similarly. Both forms need to be converted to the active form, calcitriol, to have any biological activity in the body,” Dr. Gallo explains. This is why vitamin D3 supplements are often recommended over vitamin D2; vitamin D3 raises vitamin D levels more efficiently and keeps levels elevated for longer.

When it comes to getting vitamin D from the sun, this is more complex. Dan Benardot, PhD, RD, FACSM, a registered dietitian and professor of practice at Emory University, explains that UV-beta rays from the sun create a compound called dehydrocholesterol. This compound is found in the skin and is then converted to vitamin D3.

“This way of getting vitamin D is not a safe nor sustainable source of vitamin D because of its potential for skin cancer,” Dr. Gallo says. She adds that how much vitamin D3 someone gets from the sun varies based on where they live, the time of day they’re getting sun exposure, and their melanin content.

Dr. Miner explains that the more melanin (the pigment that gives skin its color) someone has, the longer they have to be in the sun to experience the synthesis needed for producing and storing enough vitamin D. Someone who doesn’t have a lot of melanin (typically people with pale skin) needs less sun exposure.

How much vitamin D3 to take, if you’re going to take a supplement

All four nutrition experts say that signs you’re not getting enough vitamin D can be pretty vague, such as fatigue, brain fog, and feeling depressed. That means that you can be deficient in vitamin D and not even realize it. Dr. Rodriguez says that this is dangerous because it leads to absorbing less calcium from food, which can lead to weak bones. She says that it can also lead to muscle weakness.

According to all four experts, the only true way to know if you are deficient in vitamin D is through a blood test called 25-hydroxy vitamin D test. If your healthcare provider tells you that your blood work shows that you are not getting enough, then you can discuss with them if you can benefit from a supplement.

As explained before, vitamin D3 is the preferred form of vitamin D in supplement form because it raises vitamin D levels in the body more efficiently. How much vitamin D3 should you take daily? “The general guidance for most healthy adults is between 600 and 800 international units a day, which is likely sufficient to prevent bone diseases. But some experts suggest higher amounts may be necessary to have any effects on non-bone health outcomes,” Dr. Gallo says. With this in mind, Dr. Benardot recommends taking a vitamin D3 supplement with roughly 1,500 international units.

More vitamin D3 isn’t necessarily better. Dr. Benardot says that getting more than 5,000 international units of vitamin D3 a day is considered toxic. Dr. Rodriguez says that getting too much vitamin D is dangerous because it can cause calcium buildup in the arteries, which can negatively impact the cardiovascular system, including causing high blood pressure.

Considering that the amount of melanin someone has impacts how much time they should spend in the sun to get enough vitamin D, you may be wondering if this means that people with different skin colors should take different amounts of a vitamin D3 supplement. The answer is no. Dr. Benardot explains that people with high melanin content (who tend to have darker skin) typically make less vitamin D from sun exposure, making them more likely to be deficient in vitamin D compared to people with low melanin, but this does not impact the recommended supplement dose.

Even as we move into the sunniest part of the year, if you spend the majority of your time inside and are diligent about sunscreen, there’s a good chance that you could benefit from a vitamin D3 supplement. Get your bloodwork done to be sure and when choosing a vitamin D3 supplement, stick with one with a dosage of around 1,500 international units.

With those guidelines in mind, you’ll safely have your vitamin D base covered without going overboard.

This seasonal habit promotes healthy aging and may reduce dementia risk in older people

 You competent? doctor has kept you up-to-date on all appropriate vaccines, right?

This seasonal habit promotes healthy aging and may reduce dementia risk in older people

Aging is inevitable, but there’s increasing evidence that it may be possible to prevent, or at least delay, age-related diseases, including cardiovascular disease and Alzheimer’s.

Although life expectancy has soared in the United States over the past century, many people are living longer in poorer health.

That’s why many aging experts are shifting the focus away from lifespan. Instead, the goal is to maximize our “healthspan,” aka the number of years spent living into older age in good health.

And slowing down biological aging often boils down to simple, healthy choices and preventive healthcare.

Dr. Ezekiel Emanuel, an oncologist and professor of medical ethics at the University of Pennsylvania, previously spoke to TODAY.com about evidence-based habits to promote longevity, including staying up to date on routine vaccinations.

There’s one vaccine in particular that’s especially important for adults over the age of 50, says Emanuel.

Longevity Tip of The Day: Stay Up To Date With Your Flu Vaccine to Promote Healthy Aging

If you’re an adult who wants to age healthier, get your annual flu shot, says Emanuel, who authored “Eat Your Ice Cream: Six Simple Rules for a Long and Healthy Life.”

The seasonal influenza vaccine is the most effective way to protect against severe illness, complications and death from flu.

In addition to these benefits, there’s growing evidence that the flu shot may protect against age-related neurodegenerative diseases.

“Cognitive decline is a serious worry, so (getting the flu shot) is one thing you can and should do,” says Emanuel.

Why It Matters

As we get older, our body’s natural immune defenses gradually weaken, making it harder to fight off infections. People over the age of 65 face a much higher risk of getting very sick, becoming hospitalized or dying from the flu.

“Thousands of people die every year from influenza,” says Emanuel.

There’s increasing evidence showing that routine adult vaccines like the flu shot are associated with a lower risk of Alzheimer’s in older adults, TODAY.com previously reported.

“Especially for people over 50, vaccines may reduce your risk of cognitive decline and dementia,” says Emanuel.

In a 2026 study published in Neurology, researchers found that the high-dose flu shot is associated with a 55% lower risk of Alzheimer’s in adults over 65 in the years following vaccination.

In addition to the flu shot, three other routine adult vaccines may cut dementia risk, says Ezekiel. These include the shingles vaccine, pneumococcal vaccine, and the diptheria, pertussis tetanus vaccine (Tdap).

So if you’re looking to protect your body and brain as you get older, staying up to date on these shots is crucial, Emanuel says.

How to Get Started

If you have questions about the flu shot or which vaccine is appropriate for you, talk to your doctor.

The 2026-2027 seasonal influenza vaccines are available and being rolled out at pharmacies, doctors’ offices, hospitals and clinics nationwide.

There are multiple options available, including egg-based standard dose flu shots, high-dose flu shots and cell-based shots. For the first time, there is also an mRNA flu shot available to those 50 and older this year (though the dementia reduction findings only apply to the other types of flu vaccines.)

They protect against three flu viruses (two influenza A and one influenza B strain), which are expected to circulate this winter.

The best time to get a flu vaccine is in late September or October, before flu activity peaks.

It takes about two weeks for the flu shot to take full effect, and this protection generally lasts about six months through the end of flu season.

I'm a strength coach and these 6 classic exercises can help rebuild strength and improve balance after 60

 Not being able to do these post stroke IS COMPLETE INCOMPETENCE OF YOUR DOCTOR!

I'm a strength coach and these 6 classic exercises can help rebuild strength and improve balance after 60

1. Bodyweight Squat

Few exercises tell me more about someone's lower-body strength than a basic squat. You have to control yourself on the way down and produce enough force to stand back up, which is the same general demand you face every time you leave a chair. Squats also keep your ankles, knees, and hips working together while your balance shifts through the rep.

Muscles Trained: Quads, glutes, hamstrings, calves, core.

How to Do It

1. Stand with your feet about shoulder-width apart.
2. Let your toes point slightly outward if that feels natural.
3. Bend your knees and sit your hips back.
4. Lower until your thighs reach at least parallel, if comfortable.
5. Press through your feet to stand.
6. Reset and repeat.

Recommended Sets and Reps: Perform 2 to 3 sets of 8 to 12 reps. Rest for 45 to 60 seconds.

Best Variations: Chair squat, supported squat, goblet squat.

Form Tip: Keep your feet planted as you stand.

2. Push-Up

Doctor failure; did nothing to cure my spasticity so my hand can lay flat.

Push-ups have probably survived every generation of workout programs because they ask a lot from a simple movement. Your chest and arms provide the pressing strength, while your trunk keeps your body supported from head to heel. After 60, that strength can help you push yourself up, support your body with your hands, and keep your upper body capable during daily tasks.

Muscles Trained: Chest, shoulders, triceps, abs.

How to Do It

1. Place your hands slightly wider than shoulder-width apart.
2. Set your body in a straight line from your head to your heels.
3. Brace your midsection.
4. Bend your elbows and lower your chest.
5. Stop when your elbows reach about 90 degrees.
6. Press through your hands to return to the start.

Recommended Sets and Reps: Perform 2 to 3 sets of 6 to 12 reps. Rest for 45 to 60 seconds.

Best Variations: Wall push-up, incline push-up, knee push-up.

3. Reverse Lunge

Walking puts you on one leg over and over again, and lunges let you strengthen that position on purpose. Stepping backward makes the setup easier to control while your front leg does most of the work. I like reverse lunges for older clients because they build useful leg strength while also asking you to organize your balance with each rep.

Muscles Trained: Quads, glutes, hamstrings, calves, core.

How to Do It

1. Stand tall with your feet under your hips.
2. Step your right foot backward.
3. Bend both knees and lower into a comfortable lunge.
4. Keep your front foot flat.
5. Press through your front foot to stand.
6. Complete your reps, then switch sides.

Recommended Sets and Reps: Perform 2 to 3 sets of 6 to 10 reps per side. Rest for 45 to 60 seconds.

Best Variations: Supported reverse lunge, smaller-range reverse lunge, split squat.

Form Tip: Let your front leg bring you back up.

4. Standing Calf Raise

The calf raise doesn't look flashy, but it covers a strength area that becomes hard to ignore when it fades. Your calves help push you forward while walking and support ankle stability as your weight shifts. Rising onto your toes also gives you a small balance challenge without making the exercise complicated. Keep a chair or counter nearby if you want a little support.

Muscles Trained: Calves, ankles, feet.

How to Do It

1. Stand tall with your feet about hip-width apart.
2. Hold a sturdy surface lightly if needed.
3. Press through the balls of your feet.
4. Lift your heels off the floor.
5. Reach a comfortable height.
6. Lower your heels with control.

Recommended Sets and Reps: Perform 2 to 3 sets of 10 to 15 reps. Rest for 30 to 45 seconds.

Best Variations: Supported calf raise, single-leg calf raise, seated calf raise.

Form Tip: Rise straight up through the balls of your feet.

5. Forearm Plank

A strong midsection helps everything else feel more connected. The forearm plank teaches your abs to support your torso while your shoulders and hips stay in place, which helps anytime you lift, carry, or change direction. There's no movement to memorize here. The challenge is holding the position long enough to make your core work.

Muscles Trained: Abs, shoulders, glutes, upper back.

How to Do It

1. Place your forearms on the floor.
2. Set your elbows beneath your shoulders.
3. Extend your legs behind you.
4. Lift your body into a straight line.
5. Brace your abs and keep your spine neutral.
6. Hold while breathing steadily.

Recommended Sets and Reps: Perform 2 to 3 holds of 15 to 30 seconds. Rest for 30 to 45 seconds.

Best Variations: Incline plank, knee plank, full plank.

Form Tip: Keep your spine neutral throughout the hold.

5 Tips for Malnutrition and Dehydration in Older Adults

 Your competent? doctor needs to take these guidelines and CREATE EXACT PROTOCOLS for you! Can't do that: 

PURE INCOMPETENCE!

How long has your incompetent? doctor known of these problems AND DONE NOTHING?

• malnutrition (5 posts to August 2019) 
• 49% malnutrition post-stroke (2 posts to April 2025)
• muscle wasting (4 posts to September 2012)
• sarcopenia (47 posts to March 2016)
• dehydration (7 posts to February 2015)

5 Tips for Malnutrition and Dehydration in Older Adults

Malnutrition, hypertonic dehydration, and sarcopenia are common nutrition-related health concerns among adults aged 65 years or older. They can lead to functional impairment, an increased risk for complications and mortality, and delayed recovery.

Dietary measures may help prevent or address these problems and maintain or improve function and independence. Many of these recommendations are applicable to outpatient care. The revised S3 guideline, “Clinical Nutrition and Hydration in Older Adults,” outlines these recommendations.

There are five practical tips for advising patients on when to consider oral, enteral, or parenteral nutrition and how to prevent or treat hypertonic dehydration.

Tip 1: Screening for Malnutrition — Identify and Treat the Causes

All older adults should be routinely screened for malnutrition or the risk for malnutrition, ideally using validated tools such as the Mini Nutritional Assessment Short Form or the Malnutrition Universal Screening Tool. In primary care, this means screening every new older patient and at least annually screening patients with known risk factors.

Article Key Points

• Routine malnutrition screening: MNA-SF/MUST; assess causes incl dysphagia, depression, meds, isolation.
• Individualized counseling + fortified foods/snacks; target ~30 kcal/kg/d, ≥1 g protein/kg/d.
• Oral nutritional drinks between meals; monitor weight, function; consider enteral support if intake remains inadequate.
• Enteral/parenteral nutrition for chronic inadequate intake; assess RFS risk, especially 2–5 days after initiation.
• Hypertonic dehydration: thirst unreliable; prescribe fluids, diagnose with exam + labs, treat mild orally, severe IV.

Which malnutrition screening tools perform best in primary care?

How does refeeding syndrome present in frail older adults?

What predicts benefit from oral nutritional supplements?

Potential causes, including chewing or swallowing difficulties, depression, medications, and social isolation, should be identified, addressed, or compensated for whenever possible. In practice, this involves a targeted history covering eating difficulties, oral health, psychosocial factors, and polypharmacy, followed by treatment of underlying conditions, medication adjustments, and appropriate referrals, such as dental care, speech therapy, geriatrics, and social services. For more information, see the guidelines in Chapter II.1.1.

Tip 2: Nutritional Counseling and Supportive Measures

Older adults who are malnourished or at risk for malnutrition should receive individualized nutritional counseling from a certified nutrition professional. Counseling should establish realistic goals, such as maintaining weight or increasing protein and energy intake, while considering chewing and swallowing abilities, food preferences, and cultural habits. Family members and caregivers should be involved in implementing recommendations in daily life.

Home-delivered meals with high energy and protein content, combined with between-meal snacks, significantly improved the nutritional status and physical strength of older adults. Fortified foods and meals can also be useful, for example, by adding oils, creams, butters, eggs, or nuts. The goal is to increase energy and protein intake through practical measures that do not add unnecessary complexity.

If nutritional status does not improve sufficiently, primary care physicians should consider more intensive measures, such as oral nutritional supplements or enteral nutrition.

For more information, see the guidelines in Chapters II.1.3 and II.1.4.

Guidelines for Energy and Nutrient Intake in Older Adults

• Energy intake: 30 kcal/kg body weight/d.
• Protein intake: at least 1 g/kg body weight/d.
• Total fluid intake: Start with 30 mL/kg of body weight/d and adjust the amount according to individual fluid losses and the clinical situation.
• Micronutrient intake: Follow recommendations for healthy older adults unless a specific deficiency is present.
• Dietary fiber: Ensure adequate daily intake; fiber-rich foods should also be included in enteral nutrition.

These values should be individualized according to nutritional status, physical activity, health status, and tolerance.

For more information, see the guidelines in Chapter I.1.1.

Tip 3: Liquid Nutrition (Oral Balanced Diets)

Frail older adults should receive nutritional drinks as part of a comprehensive, individualized nutritional plan when their intake of regular and fortified foods is insufficient. These drinks should be offered between meals to increase energy and nutrient intake without replacing the main meals.

Primary care physicians should determine the indication, adjust the dosage to the individual patient, and monitor tolerability and target parameters, including weight and function. In patients with diabetes, renal insufficiency, or other comorbidities, disease-specific products should be selected when appropriate.

If adequate oral intake cannot be maintained over the long term, enteral nutrition should be reviewed and reassessed.

For more information, see the guidelines in Chapter II.1.6.

Tip 4: Enteral and Parenteral Nutrition

Enteral nutrition, delivered through a nasal, percutaneous gastric, or percutaneous jejunal route, may be indicated when the gastrointestinal tract is functional, but oral intake remains chronically inadequate despite conservative measures. Parenteral nutrition may be used when enteral nutrition is not possible or is contraindicated.

Primary care physicians should work with geriatricians and nutritionists to assess the indications, expected benefits, and patient preferences, particularly in patients with advanced frailty or dementia. Before nutritional support is initiated, the risk of refeeding syndrome (RFS) should be considered. In cases of severe malnutrition, nutrition should be gradually introduced. Regular reassessment is required to determine whether tube feeding remains appropriate or can be discontinued.

Older adults with low food intake in the final stages of life should receive oral nutrition tailored to their needs rather than enteral or parenteral nutrition (“comfort feeding”).

For more information, see the guidelines in Chapter II.1.7.

RFS

• RFS may occur 2-5 days after nutritional therapy is started, particularly with enteral or parenteral nutrition.
• Consequences: Volume overload and redistribution of phosphate, potassium, and magnesium into cells result in hypophosphatemia, hypokalemia, and hypomagnesemia. Thiamine is also a critical nutrient, and its deficiency can worsen RFS.
• Typical symptomsinclude muscle weakness, disorientation, and peripheral edema. Symptoms can vary and be nonspecific, making RFS particularly difficult to recognize in older adults with multiple comorbidities. Delirium can also occur.
• Untreated RFS can lead to organ failure and death.

Tip 5: Prevention and Treatment of Hypertonic Dehydration

Prevention. Older adults have an increased risk for hypertonic dehydration. Primary care physicians should recognize that thirst is an unreliable indicator and actively prescribe fluid intake for at-risk patients, such as those taking diuretics or those with fever, heat exposure, or infections. A simple drinking schedule that specifies the target amount, preferred beverages, and set times can improve adherence. Caregivers and family members should be trained to document fluid offerings, intake, and warning signs.

Suitable Beverages for Older Adults

• Water, including tap, mineral, and flavored water
• Hot or cold tea and coffee
• Milk and milk-based beverages
• Fruit juices
• Soups
• Soft drinks
• Smoothies

High-calorie and fortified beverages can be beneficial when nutrient needs are increased but should generally be avoided in people who are overweight or obese.

Diagnosis. If dehydration is suspected, physicians should systematically assess the patient’s hydration status, including medical history, thirst, dry mouth, skin and tongue findings, orthostatic symptoms, urine output, and color. Laboratory parameters, including serum osmolality, sodium, creatinine, urea, and hematocrit, support the diagnosis and help assess severity, particularly in high-risk situations, such as diuretic use or renal insufficiency. The underlying causes should also be considered, including infection, diarrhea, inadequate fluid intake, and dysphagia. This assessment determines whether oral rehydration is sufficient or intravenous therapy is necessary.

Treatment. In mild-to-moderate hypertonic dehydration, oral rehydration should be the primary treatment, using water or appropriate beverages with electrolyte supplementation, when necessary, along with close monitoring.

Intravenous fluid administration is indicated in cases of severe hypertonic dehydration or when oral intake is not possible. Primary care physicians should adjust the infusion volume and rate according to age, comorbidities such as heart or kidney failure, and laboratory results to avoid overhydration and underhydration. The underlying causes of dehydration, such as infection, excessive diuretic use, diarrhea, or vomiting, should also be treated. Once a patient has stabilized, a long-term prevention plan should be established, including fluid intake goals, monitoring, and education for patients, family members, and caregivers.

Physicians should also consider parenteral fluid administration as a medical treatment rather than basic care and carefully weigh its benefits and risks.

For more information, see the guidelines in Chapters III.1-III.3.

What Else the Guideline Covers

The S3 guideline “Clinical Nutrition and Hydration in Older Adults” is divided into five chapters containing 69 consensus recommendations, many of which are new. For example, Recommendation 20 states: “In addition to nutritional interventions, older adults who are malnourished or at risk of malnutrition should be encouraged to be physically active and, if possible, to participate in a structured exercise program to maintain or improve muscle mass and function.”

The guideline also provides recommendations on the prevention and treatment of malnutrition associated with common geriatric diseases and symptoms, including hip fracture, delirium, pressure ulcers, chronic obstructive pulmonary disease, diabetes, dementia, and dysphagia (Chapter II.2). It also includes dietary recommendations for sarcopenia (Chapter IV) and overweight and obesity (Chapter V).
