The rising summer temperatures may offer more opportunities to enjoy the outdoors and come with an increased risk of heatstroke. Planning for hot days allows you to enjoy the longer, warmer days without suffering when the temperatures rise.
Who Is at Risk of Medical Concerns in the Heat?
Anyone can become ill from too much time in extreme temperatures. However, some people are more likely to suffer from medical concerns stemming from too much time in the heat. These people include:
- Those with chronic medical conditions
- Those with mental illness
- People on certain medications
- Those with limited mobility
- People over the age of 65
- Babies and young children
- Overweight or obese people
- Those who work or exercise outdoors
Additionally, people who are more accustomed to cooler climates may be more affected by hotter temperatures.
How to Stay Safe in the Heat
When temperatures rise, people are more likely to become dehydrated, which can cause cramps, exhaustion, or heat stroke. Some tips for staying healthy in the heat include:
- Drink plenty of water
- Eat foods high in water
- Wear sunscreen
- Stay in the shade
- Avoid being out in the hottest part of the day
- Wear light-colored, loose-fitting clothing
- Avoid strenuous activities
- Use wet towels or cool (not cold) showers to keep from overheating
It’s essential to check on friends and family in times of extreme heat and have them check on you.
Prepare for High Temperatures
Right now is the time to ensure your safety in extreme temperatures. Prevent any issues when temperatures rise by taking the time to ensure your safety and comfort in cases of extreme heat. Some actions to take include:
- Knowing the signs of heat-related illnesses
- Identifying cool areas in your community where you can go
- Purchase window deflectors to reflect heat outside
- Install window air conditioners and insulate around them
If you have a whole-house air conditioner, check your unit to ensure it doesn’t need any maintenance or repairs before summer temperatures rise.
If You Experience Heat-Related Symptoms
If you experience heat cramps or heat exhaustion signs, go to a cooler location and remove excess clothing. Sip sports drinks or water, and call a healthcare provider if symptoms worsen or persist for more than an hour.

Multiple sclerosis (MS) is a chronic inflammatory disease that attacks myelin, the protective sheath that covers nerves and causes progressive and serious communication issues between the brain, central nervous system, and the rest of the body[1].
Currently, it’s estimated that over 2.3 million people worldwide, and over one million people in the US have a diagnosis of MS[2].
While there have been significant improvements in treatments designed to stabilize, delay, and even improve symptoms of MS, new and more effective treatments are needed to improve the long-term outcome associated with the condition.
One area currently being investigated as a potential therapeutic option for treating MS is the use of regenerative medicine, also known as stem cell therapy, and specifically treatment using mesenchymal stem cells (MSCs).
In this review of evidence from preclinical and clinical studies, Gugliandolo et al. examine studies involving the use of MSCs or their derivatives in vivo models of MS and patients affected by MS. The authors also examine and discuss the feasibility of autologous MSCs therapy for MS patients.
Specifically, and when assessed in terms of effectiveness when treating MS, the therapeutic potential of MSCs was associated with their differentiation capacity and paracrine effects, their ability to differentiate toward oligodendrocytes and express oligodendrocyte progenitor cell (OPC) markers, and their capacity for homing (moving towards the damaged area following chemical gradients).
As part of this review, the authors also examined the effectiveness of various sources of MSC in MS models, these sources included bone marrow MSCs (BM-MSCs), adipose tissue-derived MSCs (AD-MSCs), periodontal ligament stem cells (PDLSCs), skin-derived MSCs (S-MSCs), Wharton’s jelly-derived MSCs (WJ-MSCs), human umbilical cord MSCs (UCMSC), human amnion mesenchymal cells (AMCs), placental derived MSCs (PMSCs), and decidua derived MSCs (DMSCs). According to the research reviewed by Gugliandolo et al., all MSCs, regardless of where they were harvested from, demonstrated beneficial effects in the therapeutic treatment of MS.
Specifically, the results demonstrated that MSCs were able to produce some form of protective effects in reducing inflammatory cell infiltration, disease score, demyelination, and blood-brain barrier disruption.
A review of 29 phase 1 or 2 clinical trials registered on clinicaltrials.gov demonstrated that MSCs, regardless of the type and method of administration, demonstrated to be safe and absent of severe adverse effects with the majority demonstrating measurable improvements when used in MS patients.
While clinical trials demonstrated the safety of administration of MSC in MS patients, the authors were particularly interested in learning if autologous MSC transplantation presented some advantages over heterologous administration.
The authors of this review found that samples obtained from healthy controls and MS patients showed similar features, indicating the possibility of autologous stem cell therapy in MS patients. However, other studies found that MSCs obtained from MS patients exhibited a different transcriptional pattern and fewer immunosuppressive functions compared to healthy donor MSCs.
Gugliandolo et al. point out that limits to these experimental studies include the use of animals of a single gender, given that sex-dependent differences exist and the use of different MS models, different number of transplanted cells, different MSCs sources, and routes of administration. These limitations make it difficult to define the optimal treatment in terms of cell type, dose, and administration conditions.
The authors conclude that clinical trials demonstrate the safety and feasibility of MSCs treatment, and also some improvements, but more data on larger cohorts are required to establish their efficacy. Considering the controversial results pertaining to the features of MSCs derived from MS patients, the authors also call for additional research in order to conclusively determine the safety and efficacy of autologous MSCs therapy in MS patients.

Regenerative medicine, also known as stem cell therapy, is emerging as a viable treatment for Parkinson’s disease as clinical trials move through the FDA approval process. Patients in clinical trials see positive results from mesenchymal stem cell therapy for Parkinson’s Disease.
What Is Parkinson’s Disease?
Parkinson’s disease is a progressive, neurodegenerative condition. It occurs when dopamine-producing brain cells stop working or die. Dopamine’s role in the body is to send messages between nerve cells or from nerve cells to muscle cells, affecting the body’s physical and mental functions.
Symptoms of Parkinson’s start gradually, and the disease worsens over time. Early symptoms include tremors in the hands, rigidity, and slowness of movement. Patients with Parkinson’s also experience difficulty with balance, and eventually, with speech, writing, and automatic muscle movement such as blinking.
While there’s currently no cure for Parkinson’s, there are medications that patients can take to manage symptoms. Some symptoms are also relieved from surgery to regulate specific brain areas.
Patients with Parkinson’s disease experience a progressive decline in their ability to function, with treatments only offering some relief. The emergence of mesenchymal stem cell therapy as an option to reverse the damage and halt the progression of Parkinson’s disease is an exciting development.
What Are Mesenchymal Stem Cells?
Stem cells are considered to be the building blocks of cells. All specialized cells in the body come from stem cells. When stem cells divide, they either produce more stem cells, called daughter cells, or differentiate into specialized cells, such as bone, blood, or brain cells.
Mesenchymal stem cells (MSCs) are adult stem cells commonly found in bone marrow. They also exist in adipose (fat), umbilical cord tissue, amniotic fluid, and other locations. MSCs remain dormant in the bone marrow until they’re needed to facilitate healing in the body.
MSCs differentiate into:
- Bone cells
- Muscle cells
- Skin cells
- Cartilage
- Neural cells
- Corneal cells
MSCs are present throughout your life, but they age as the body ages, making them less effective and concentrated over time.
How Can Mesenchymal Stem Cells Benefit Those with Parkinson’s Disease?
In recent clinical trials using mesenchymal stem cells on Parkinson’s patients, the cells significantly improved patients’ symptoms, including facial expressions, gait, and rigidity or “freezing” episodes. Some of the patients in this study substantially reduced their dosages of medicines used to control Parkinson’s symptoms.
In a 2005 study, researchers determined that stem cells may be capable of differentiating into dopamine neurons, which are damaged or destroyed with Parkinson’s.
While the true potential of mesenchymal stem cell benefits in Parkinson’s patients is still being investigated, there is reason to believe that patients with the neurodegenerative condition could experience a significant improvement in their quality of life with stem cell therapy.

Articular cartilage, found on the surface of most musculoskeletal joints, distributes and transfers forces between bones and joints, provides a smooth surface for joint mobility, and plays an important role in human mobility.
However, articular cartilage is also easily susceptible to damage, but difficult to repair itself on its own (primarily due to the fact it is mostly avascular). Over time, the inability of articular cartilage to repair itself leads to progressive joint pain, disfigurement, movement disorders, and ultimately osteoarthritis.
The CDC estimates that nearly 33 million Americans are currently affected by osteoarthritis, most often in the form of pain, stiffness, decreased mobility and range of motion, and swelling in the joints[1].
Current treatment methods, including microfracture technology, autologous or allogeneic cartilage transplantation, and autologous chondrocyte implantation (ACI) have demonstrated the ability to repair and regenerate fibrous cartilage, but not articular cartilage required for smooth, fluid, natural mobility.
To address this issue, recent research has focused on the efficacy of stem cells, and specifically mesenchymal stem cells (MSCs) found in bone marrow, adipose tissue, synovial membrane, and umbilical cord Wharton’s jelly, as potential therapeutic treatments for regeneration of articular cartilage. MSCs are particularly of interest due to their demonstrated abilities of self-renewal, multi-differentiation, and immunoregulation.
While the use of MSCs has demonstrated tremendous potential in the field of regenerative therapy, one notable drawback continues to be unstable or suboptimal results resulting from the heterogeneity of various mesenchymal stem cells.
Specifically, the stability and efficacy of MSCs appear to differ based on a number of factors, including the donor, the tissue source, and their ability for proliferation, differentiation, and immunoregulation.
For example, some of the key heterological differences highlighted in this review include the efficacy of MSCs based on donor’s age (with younger donors providing higher quality MSCs), Wharton’s Jelly MSCs showing greater prospects for application in cartilage regeneration than other MSCs, and differences within specific MSC subpopulations.
The authors of this review acknowledge the potential of MSCs in repairing arterial cartilage, but also point out that there needs to be a deeper understanding of the heterogeneity of various MSCs in order to improve the efficiency of MSC-based therapies designed to repair arterial cartilage. In addition, the authors also call for greater standardization in MSC isolation and harvesting methods among laboratories in order to provide better consistency with respect to results obtained from studies using MSCs.

Neurodegenerative conditions such as Alzheimer’s disease (AD), Parkinson’s disease (PD), and amyotrophic lateral sclerosis (ALS) occur when neuron populations begin to diminish. There is currently no cure for these types of diseases, though clinical trials to explore various treatment options are ongoing. In particular, regenerative medicine, also known as stem cell therapy, is being heavily researched and has shown remarkable progress in controlling these conditions.
Types of Stem Cells
Stem cells serve as the foundation for every tissue and organ throughout the body. They are unspecialized but have the incredible ability to differentiate into virtually any cell type, as well as the power to self-renew.
Neurodegenerative conditions are characterized by neurons that progressively lose their function and structure, and eventually die off. Because stem cells are able to differentiate into multiple cell types, researchers have begun exploring whether they could replace or repair damaged neurons to control the progression of, or potentially even reverse the damage done by, these illnesses. Existing treatment options are limited, but many researchers are optimistic about stem cells’ potential.
Not all stem cells are the same. Here are the various types, some of which show more efficacy as a treatment for neurodegenerative disease than others:
- Tissue-specific stem cells: These somewhat specialized stem cells can generate multiple organ-specific cells and are typically located in areas of the body that can self-replenish, such as the skin and blood.
- Embryonic stem cells (ESCs): Located in blastocysts, ESCs are especially promising in neurodegenerative applications. Yet, they do pose some risks, including the risk of rejection. Due to their ability to differentiate into neurons, however, they continue to be studied as a potential therapy.
- Induced Pluripotent Stem Cells (iPSCs): iPSCs are artificially derived from adult cells and programmed back to pluripotency, thereby allowing for an unlimited source of any cell type. While they are widely used for developing medications and disease modeling, further research must be done to refine the reprogramming process.
- Mesenchymal Stem Cells (MSCs): MSCs can differentiate into several types of cells. Their self-renewal capabilities are far-reaching, making them an ideal candidate for therapies involving tissue repair. They may also be leveraged for cell transplantation in the treatment of neurodegenerative diseases.
- Neural Stem Cells (NSCs): NSCs are derived from specific areas of the brain and are therefore specialized cells. They, too, are self-renewing and multipotent.
Types of Neurodegenerative Conditions Regenerative Medicine can Help Manage:
While researchers are uncovering new findings on how stem cells can treat neurodegenerative conditions nearly every day, there has already been progress. Here are some of the conditions stem cell therapy has been used to manage:
- Parkinson’s Disease (PD): One hallmark characteristic of PD is the decline of dopamine, caused by the destruction of dopamine-producing brain cells. As dopamine decreases, symptoms such as muscle tremors, challenges with movement, and difficulty thinking arise. Now, researchers have found that stem-cell-derived dopaminergic neurons — in particular, those created through ESCs and iPSCs — could hold success in replacing the destroyed brain cells in individuals with PD.
- Alzheimer’s Disease: Through the use of stem cell therapy, researchers at Columbia University have refined the protocol for a unique process of converting skin cells into brain cells. This option streamlines the process of creating neurons to replace those which have become damaged by Alzheimer’s disease. In their research, the cells were able to receive signals just as normal neurons would.
- ALS: ALS has proven remarkably challenging to study, as there are many potential causes and therapies may therefore only be effective on specific patient populations. Moreover, the motor neurons, which are directly impacted by the condition, couldn’t be acquired in large enough numbers to study. Now, however, Harvard researchers have been able to derive mature cells that can be manipulated back into stem cells from ALS patients, opening up new doors for studying potential therapies to treat the condition.
While there is more ground to cover before stem cell therapy for neurodegenerative conditions can become mainstream, promising research is consistently being published. Moving forward, it’s likely that stem cells will hold the answer to viable management options for these and other challenging conditions.
