“Post-stroke” or “post-stroke period” refers to the period of time following a stroke. A stroke occurs when there is a sudden disruption of blood flow to a part of the brain, leading to brain cell damage and, potentially, the death of brain tissue. The severity and specific consequences of a stroke depend on various factors, such as the type of stroke (ischemic or hemorrhagic) and the location and size of the affected brain area.
The post-stroke period is a critical time for stroke survivors as they begin their recovery and rehabilitation journey. During this period, individuals may experience a range of physical, cognitive, emotional, and social challenges. The post-stroke phase can vary in duration and intensity depending on the extent of brain damage and the effectiveness of treatment and rehabilitation.
Some common aspects and challenges of the post-stroke period include:
Medical stabilization: In the immediate aftermath of a stroke, medical professionals focus on stabilizing the patient, preventing further damage, and addressing any potential complications.
Acute care and rehabilitation: Once the individual’s condition is stable, they may undergo rehabilitation, which may involve physical therapy, occupational therapy, speech therapy, and other specialized treatments to help restore lost functions and improve independence.
Physical recovery: Many stroke survivors experience weakness, paralysis, or difficulty with mobility. Physical therapy aims to help them regain strength, balance, and coordination.
Cognitive recovery: Depending on the area of the brain affected, stroke survivors may experience difficulties with memory, attention, language, and problem-solving. Cognitive rehabilitation can assist in addressing these issues.
Emotional and psychological support: Stroke can have significant emotional and psychological impacts. Depression, anxiety, and frustration are not uncommon during the post-stroke period.
Social reintegration: Stroke survivors may face challenges in reintegrating into their communities and resuming their daily activities. Support from family, friends, and support groups can be essential during this phase.
Long-term management: For some individuals, the effects of a stroke may be permanent, necessitating ongoing care and management of any residual disabilities or health issues.
The post-stroke period is highly individual, and recovery outcomes can vary widely from person to person. Early intervention, rehabilitation, and ongoing support play vital roles in improving the quality of life for stroke survivors.
Diagnosing a stroke typically involves a combination of clinical evaluation, medical history assessment, and imaging tests. Rapid and accurate diagnosis is crucial because time is of the essence when it comes to stroke treatment.
The faster a stroke is diagnosed and treated, the better the chances of minimizing brain damage and improving outcomes.
What Are The Different Types of Stroke?
There are two main types of strokes: ischemic stroke and hemorrhagic stroke. Each type has different underlying causes:
Ischemic strokes account for about 85% of all strokes and occur when there is a blockage or narrowing of a blood vessel supplying blood to the brain. This blockage can be due to a blood clot (thrombus) that forms within a blood vessel in the brain (cerebral thrombosis) or elsewhere in the body and travels to the brain (cerebral embolism).
Common risk factors for ischemic stroke include atherosclerosis (the buildup of fatty deposits in the blood vessels), high blood pressure (hypertension), diabetes, high cholesterol levels, smoking, and certain heart conditions such as atrial fibrillation.
Hemorrhagic strokes occur when a blood vessel in the brain ruptures, causing bleeding into or around the brain tissue. The bleeding puts pressure on brain cells and can damage them.
The two main types of hemorrhagic stroke are intracerebral hemorrhage (bleeding within the brain) and subarachnoid hemorrhage (bleeding into the space between the brain and the thin tissues that cover it).
Hypertension is a significant risk factor for hemorrhagic stroke, as it can weaken blood vessel walls over time. Other risk factors include brain aneurysms, arteriovenous malformations (AVMs), and certain blood-thinning medications.
How Can I Avoid a Potential Stroke?
It’s important to note that certain lifestyle factors and medical conditions can increase the risk of stroke. These include:
How Do You Know If You Are Having or Have Had a Stroke?
If you suspect someone is having a stroke or experience symptoms yourself, it’s crucial to seek immediate medical attention as prompt treatment can minimize brain damage and improve outcomes. Remember, “FAST” is a simple way to remember the most common symptoms of a stroke:
F – Face drooping A – Arm weakness S – Speech difficulty T – Time to call emergency services.
Recognizing the symptoms of a stroke is crucial because immediate medical attention can greatly improve the chances of minimizing brain damage and improving outcomes. The symptoms of a stroke can vary depending on the type of stroke (ischemic or hemorrhagic) and the part of the brain affected.
Here are some common signs and symptoms of a stroke:
Sudden numbness or weakness: You may experience sudden numbness or weakness in the face, arm, or leg, typically affecting one side of the body. A common indicator is drooping on one side of the face when trying to smile.
Trouble speaking or understanding speech: You might have difficulty speaking coherently or understanding what others are saying. Your speech may become slurred or difficult to comprehend.
Confusion or trouble with comprehension: You may feel confused, disoriented, or have difficulty understanding simple instructions or questions.
Sudden severe headache: A sudden, severe headache that is different from any previous headaches you’ve experienced may be a warning sign of a stroke, especially if it’s accompanied by other symptoms.
Trouble with vision: You may experience sudden blurred or double vision or have trouble seeing out of one or both eyes.
Dizziness or loss of balance: You may feel dizzy, lightheaded, or have trouble maintaining your balance, leading to difficulty walking or coordination problems.
hemorrhagic strokes) to prevent further damage to the brain. Rehabilitation and support following a stroke are also essential for recovery and regaining function.
What Treatments Are There for Post Stroke Care?
Post-stroke care focuses on the rehabilitation and management of stroke survivors to improve their physical, cognitive, emotional, and social functioning. The specific treatments for post-stroke care depend on the individual’s needs and the extent of the stroke’s impact. Here are some common components of post-stroke care and treatments:
Emotional support and counseling
Social and vocational support
Post-stroke care is often a multidisciplinary approach, involving a team of healthcare professionals working together to develop a personalized treatment plan. The goal is to maximize the individual’s functional recovery, promote independence, and enhance their overall quality of life after a stroke. As each stroke survivor’s situation is unique, the treatment plan will be tailored to their specific needs and abilities. Regular follow-up appointments and ongoing support are essential components of post-stroke care to monitor progress and adjust treatment as necessary.
Mesenchymal stem cells (MSCs) are unique cells that have the ability to differentiate into different cell types and self-renew, meaning they can produce more stem cells. MSCs are a type of adult stem cell found in various tissues, such as bone marrow and adipose (fat) tissue. They have the unique ability to differentiate into different cell types and secrete bioactive molecules that can promote tissue repair and modulate the immune response.
In the context of post-stroke care, MSC therapy aims to harness the regenerative and immunomodulatory properties of these stem cells to potentially enhance neurological recovery and reduce post-stroke complications.
Several preclinical studies and early-phase clinical trials have investigated the safety and potential benefits of MSC therapy for stroke. Here are some potential ways MSCs might exert beneficial effects in post-stroke patients:
Neuroprotection: MSCs have been shown to secrete factors that protect neurons from further damage and promote cell survival in animal models of stroke.
Anti-inflammatory effects: After a stroke, inflammation in the brain can exacerbate damage. MSCs can modulate the immune response, reducing harmful inflammation and promoting a more favorable environment for recovery.
Angiogenesis: MSCs can support the formation of new blood vessels (angiogenesis) in damaged brain tissue, improving blood flow and oxygen supply to the affected areas.
Neuroplasticity: MSCs may help enhance brain plasticity, which is the brain’s ability to reorganize and form new neural connections, potentially aiding recovery and functional improvements.

According to the CDC, an estimated 3.1 million adults (1.3%) in the United States have been diagnosed with inflammatory bowel disease (IBD), which includes Crohn’s disease (CD) and ulcerative colitis.
Characterized by abdominal pain, severe diarrhea, fatigue, weight loss, and malnutrition, CD is thought to be the result of swelling and inflammation of the tissue of the digestive tract.
To date, there is not a clearly prescribed method for the treatment or prevention of CD. However, recently, researchers have found stem cells to be a promising treatment option, primarily for the observed ability to regulate immunity, repair injury, and control inflammation.
Building on the positive findings of previous studies that have used autologous stem cells or adipose-derived stem cells to treat CD and its associated complications, Zhang et al.’s randomized controlled clinical trial examines the use of umbilical cord mesenchymal stem cells (UC-MSCs) as a treatment for CD.
This study followed 82 patients who had been diagnosed with CD and had received steroid maintenance therapy for more than 6 months. Half of the participants were randomly assigned to receive a series of four peripheral intravenous infusions of UC-MCSs/kg administered over the course of a four-week period. Then, by using the Crohn’s disease activity index (CDAI) Harvey-Bradshaw Index (HBI), and corticosteroid dosage, participants in both the control and experimental group were followed up with over a 12-month period.
At the conclusion of this study, Zhang et al. found that the group receiving umbilical cord mesenchymal stem cells infusion experienced a significant decrease in the required dosage of corticosteroid dosage and a significant improvement in the overall condition of the patients. These findings led the authors to conclude that UC-MSCs can attenuate immune malfunction in patients with CD. Considering these findings, the authors suggest that the mechanisms of UC-MSC efficacy in CD be elucidated to better understand the precise selection of patients who receive this specific stem-cell treatment in the future.
The authors point out that, while the specific mechanisms of alleviating CD by UC-MSCs remain obscure, it is suggested that the downregulation of proinflammatory cytokines serves a beneficial role in the process.
The authors also raise concerns over the safety of the clinical application of stem cells in this application, highlighting conflicting findings as to the safety of the process. Considering the prevalence of stem cells’ ability to regulate and suppress immunity in other studies, Zhang et al. infer that the patient infections observed during their trial were associated with immunosuppression by stem cells.
While the study suggested that the peripheral infusion of UC-MSCs was convenient and safe, the authors point out that there was little distribution of UC-MSCs in the intestinal tissue and risk of cells being retained in the pulmonary capillaries. As a result, the authors call for future studies comparing the efficacy of interventional infusion into the inferior mesenteric artery to that of peripheral infusion.

Researchers continue to tout the potential of mesenchymal stem cells (MSCs) as an evolving approach for the repair of damaged tissue or lost cells.
Specifically, the ability of MSCs to differentiate and secrete beneficial factors and vesicles is believed to play the most influential role in the regeneration of injured tissues and cells affected by various diseases.
Recently, research into the regenerative potential of MSCs has focused on the extracellular vesicles (EVs) secreted by MSCs as an emerging and potential non-cellular therapeutic approach for healing or repairing injured or damaged tissue.
MSC-derived EVs (MSC-EVs), or cell-free therapies, in contrast to treatments based on whole cells, are easier to manage and safer due to lower amounts of membrane-bound proteins such as MHC molecules and their inability to directly form tumors.
In this review, Keshtkar et al. discuss and describe the extracellular vesicles released by MSCs and their therapeutic potential for addressing different disease models.
These EVs are membrane-packed vesicles that are secreted by a variety of cell types and found in a variety of physiological fluids. In addition to MSCs, EVs are also secreted by T cells, B cells, dendritic cells, platelets, mast cells, epithelial cells, endothelial cells, neuronal cells, cancerous cells, and embryonic cells. EVs are also found in urine, blood, breast milk, saliva, cerebrospinal fluid, synovial fluid, and amniotic fluid.
EVs have repeatedly demonstrated that they perform an important role in cell-to-cell communication and have been implicated in a number of important processes, including the immune response, homeostasis maintenance, coagulation, and inflammation.
Several studies have explored the use of MSC- EVs as therapeutic treatment options for kidney disease, liver disease, cardiovascular disease, and neurological disease. The authors of this review report the beneficial therapeutic effects of MSC-EVs in each of the disease models listed above, which include a significant reduction in inflammation, improved angiogenesis, reduced oxidative stress, the suppression of fibrosis, and increased cell proliferation.
Keshtkar et al. conclude that EVs can be easily isolated from MSCs of various origins and can be transferred to target cells to introduce therapeutic effects that include the regeneration of tissue and suppression of inflammation. Additionally, the authors point out that EVs could be an effective, safe therapeutic option.
Considering the potential therapeutic benefits of MSC-EV regenerative therapy, the authors suggest standardizing methods for EV isolation, characterization, and administration as ways to provide safe, effective, and powerful new therapies based on MSC-EVs.
Kidney disease, also known as renal disease or nephropathy, refers to a condition in which the kidneys are damaged or unable to function properly. The kidneys play a crucial role in filtering waste products, excess fluid, and toxins from the blood, while also maintaining the body’s electrolyte balance and producing important hormones. When kidney disease occurs, these vital functions are compromised, leading to a range of complications.
What Causes Kidney Disease?
Kidney disease can affect people of all ages and backgrounds. Kidney disease can have various causes, and understanding these underlying factors is crucial in managing the condition effectively. There are several primary causes of kidney disease:
Diabetes: Diabetes is a leading cause of kidney disease. High blood sugar levels can damage the blood vessels in the kidneys over time, impairing their ability to function properly. This condition, known as diabetic nephropathy, can progress to chronic kidney disease and ultimately lead to kidney failure.
Hypertension (High Blood Pressure): Uncontrolled high blood pressure puts excessive strain on the blood vessels in the kidneys, leading to their damage. Over time, this can result in chronic kidney disease. Conversely, kidney disease can also cause hypertension, creating a harmful cycle.
Glomerulonephritis: Glomerulonephritis refers to inflammation of the glomeruli, which are tiny filters in the kidneys responsible for removing waste from the blood. This inflammation can be triggered by infections, autoimmune disorders, or certain medications, leading to kidney damage and impaired function.
Polycystic Kidney Disease (PKD): PKD is a genetic disorder characterized by the growth of fluid-filled cysts in the kidneys. These cysts gradually enlarge and interfere with kidney function, ultimately leading to kidney failure.
Urinary Tract Obstruction: Kidney disease can also result from obstructions in the urinary tract, such as kidney stones, tumors, or an enlarged prostate gland. These blockages can disrupt the normal flow of urine, causing kidney damage and infection.
Infections: Severe or recurrent kidney infections, such as pyelonephritis, can cause inflammation and scarring of the kidneys. If left untreated, these infections can lead to chronic kidney disease.
Medications and Toxins: Certain medications and toxins can damage the kidneys if used improperly or in excessive amounts. Examples include nonsteroidal anti-inflammatory drugs (NSAIDs), certain antibiotics, and illicit drugs.
It’s important to note that some individuals may have a combination of risk factors that contribute to kidney disease. Additionally, early detection, regular monitoring, and proper management of these underlying causes can significantly slow the progression of kidney disease and help preserve kidney function.
What Are the Symptoms?
The symptoms of kidney disease may vary depending on the stage and underlying cause but often include fatigue, swelling in the legs and ankles, frequent urination, foamy or bloody urine, persistent itching, and high blood pressure. However, in the early stages, kidney disease may be asymptomatic, making early detection and regular screening crucial, especially for individuals with risk factors.
If you suspect that you have kidney disease, it is crucial to take immediate action and seek medical attention. If kidney disease is diagnosed, it is vital to follow the advice and treatment plan provided by your healthcare professional.
Kidney disease requires ongoing monitoring to assess kidney function, evaluate the progression of the disease, and adjust treatment if necessary. Your healthcare professional will schedule regular follow-up appointments to review your progress, conduct further tests as needed, and make any necessary adjustments to your treatment plan.
Coping with a chronic condition like kidney disease can be emotionally challenging. Consider reaching out to friends, family, or support groups who can provide encouragement, share experiences, and offer practical advice. Support from others who understand the journey can be invaluable.
Left untreated, kidney disease can lead to serious complications such as fluid retention, electrolyte imbalances, anemia, bone disorders, cardiovascular problems, and ultimately kidney failure. In end-stage renal disease, patients may require dialysis or a kidney transplant to sustain life.
What are Kidney Disease Treatments?
Management of kidney disease involves a combination of lifestyle modifications, medication, and, in some cases, medical procedures. Treatment aims to slow the progression of the disease, control symptoms, and prevent complications. Lifestyle changes may include maintaining a healthy diet with controlled salt and protein intake, staying adequately hydrated, exercising regularly, managing blood pressure and blood sugar levels, and avoiding smoking and excessive alcohol consumption.
MSC therapy has shown promising potential for the treatment of kidney diseases. MSCs are a type of adult stem cell that can be isolated from various sources, including bone marrow, adipose tissue, and umbilical cord tissue.
In the context of kidney disease, stem cells have been studied for their regenerative and immunomodulatory properties. They have the ability to differentiate into different cell types, including kidney cells, and can also release various growth factors and cytokines that promote tissue repair and modulate the immune response. Here are some key points regarding the potential of MSC therapy for kidney disease:
Acute Kidney Injury (AKI): MSC therapy has been investigated as a potential treatment for AKI, a sudden loss of kidney function. Studies have shown that MSCs can enhance kidney repair, reduce inflammation, and improve kidney function in animal models of AKI. Clinical trials are underway to evaluate the safety and efficacy of MSC therapy for AKI in humans.
Chronic Kidney Disease (CKD): MSC therapy holds promise for the treatment of CKD, a progressive loss of kidney function over time. MSCs have been shown to have beneficial effects on renal fibrosis, inflammation, and oxidative stress, which are key factors in CKD progression. Preclinical studies have demonstrated that MSCs can ameliorate kidney damage and improve kidney function in animal models of CKD.
Immune modulation: MSCs possess immunomodulatory properties, which can be advantageous in kidney diseases with an immune component, such as autoimmune kidney diseases (e.g., lupus nephritis). MSCs can suppress abnormal immune responses, reduce inflammation, and promote tissue repair, thereby potentially mitigating the immune-mediated damage to the kidneys.
Safety and Delivery: MSC therapy has been generally considered safe, with no significant adverse effects reported in studies. Delivery methods vary but may include intravenous infusion or direct injection into the renal tissue during surgical procedures.
Kidney disease is a condition characterized by impaired kidney function, which can arise from various causes. Early detection, regular monitoring, and appropriate management are essential to slow the progression of the disease, maintain kidney function, and prevent complications. It is important for individuals with risk factors or concerning symptoms to seek medical attention for proper evaluation and treatment.
Osteoarthritis (OA) is the most common and widespread form of arthritis, affecting an estimated 655 million people worldwide. Occurring as a result of cartilage degeneration, OA is a progressive degenerative disorder that most commonly affects the joints of the hands, hips, knees, and spine.
Although OA can affect anyone, it is most commonly observed in older patients. In fact, all individuals over the age of 65 are believed to demonstrate some clinical or radiographic evidence of OA.
While surgical and pharmaceutical treatment options for OA exist as a way to manage the symptoms and progression of the disease, treatment for the restoration of normal cartilage function has yet to be achieved.
Considering the tissue of joint cartilage is composed primarily of chondrocytes found in bone marrow-derived mesenchymal stem cells (BMSCs), using these specific stem cells appears to have significant potential for use in the therapeutic regeneration of cartilage.
In this review, Gupta et al. evaluate the advances in using BMSCs and their therapeutic potential for repairing cartilage damage in OA. Evaluating current research, the authors point out that one of the key characteristics of MSCs, including BMSCs, is that they are generally hypoimmunogenic and possess immunosuppressive activity, suggesting that BMSCs could be used as allogeneic applications for cartilage repair.
Preclinical models of OA have also demonstrated that the effects of MSC transplantation have been effective for cartilage repair. Additionally, clinical models have reported on the safety and positive therapeutic effects of MNSC administration in patients with OA.
The authors point out that while the exact mechanism by which BMSCs regenerate articular cartilage in patients with OA is not clear, their ability to induce proliferation and tissue-specific differentiation appears to aid in the repair of damaged cartilage.
The ability of BMSCs to migrate and engraft onto multiple musculoskeletal tissues and differentiate at the site of injury while demonstrating anti-inflammatory and immunosuppressive properties demonstrate their potential as a therapeutic treatment for degenerative diseases like OA.
While the information provided in this review demonstrates the potential of BMSCs to support treatment and recovery from the damage caused because of OA, Gupta et al. call for additional clinical studies to assess the curative properties and long-term outcome of using MCSCs for the treatment of OA before they can be used routinely as a clinical treatment for the condition.
