The sensation of cold hands is a common complaint, especially in chilly weather. However, for some individuals, this discomfort is more than just a response to the environment. It might be an indication of a condition known as Raynaud’s phenomenon. In this article, we will explore the world of cold hands, and understand what Raynaud’s phenomenon is, its causes, symptoms, diagnosis, and management.
Raynaud's disease, also known as Raynaud's phenomenon or Raynaud's syndrome, is a condition that affects blood flow to certain parts of the body—usually the fingers and toes. In Raynaud's disease, smaller arteries that supply blood to the skin constrict excessively in response to cold or stress, limiting blood supply to affected areas (vasospasm). This can lead to numbness, tingling, and color changes in the affected areas, typically turning them white or blue.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
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!

Cold Hands? It could be Raynaud’s Phenomenon
1. Cold Hands? It could be Raynaud’s
Phenomenon
The sensation of cold hands is a common complaint, especially in chilly weather. However, for
some individuals, this discomfort is more than just a response to the environment. It might be an
indication of a condition known as Raynaud’s phenomenon. In this article, we will explore the
world of cold hands, and understand what Raynaud’s phenomenon is, its causes, symptoms,
diagnosis, and management.
The Chilling Reality of Cold Hands
Cold hands are a universal experience. We’ve all felt our fingers turn icy when exposed to cold
temperatures, and it’s typically a normal and temporary reaction. Your body’s natural response to
cold is to conserve heat and redirect blood flow to vital organs, leading to a decrease in blood
circulation to the extremities, such as the hands. However, in some cases, the experience of cold
hands goes beyond what can be explained by temperature alone. People with Raynaud’s
phenomenon often encounter extreme sensitivity to cold and stress, leading to dramatic color
changes in their fingers, typically from white to blue to red. This condition is more than just an
occasional inconvenience; it can significantly impact one’s quality of life.
Understanding Raynaud’s Phenomenon
Raynaud’s phenomenon, often referred to simply as Raynaud’s, is a vascular disorder that affects
the blood flow to the extremities, primarily the fingers and toes. It’s characterized by vasospasms,
where the blood vessels constrict and narrow excessively in response to cold temperatures or
2. emotional stress. This constriction restricts the blood flow to the affected areas, leading to the
classic symptoms of Raynaud’s, including cold and discolored fingers.
Raynaud’s can be classified into two main categories:
1. Primary Raynaud’s: This is the most common form, and its exact cause is unknown. It
usually occurs in people between the ages of 15 and 25, and while it can be uncomfortable, it
is typically not associated with any underlying medical conditions.
2. Secondary Raynaud’s: This type of Raynaud’s is often a result of an underlying medical
condition, such as an autoimmune disorder (e.g., systemic sclerosis), vascular diseases, or
exposure to certain medications or chemicals.
Symptoms of Raynaud’s Phenomenon
The hallmark symptom of Raynaud’s phenomenon is a tri-phasic color change in the affected
fingers or toes, proceeding from white to blue and finally to red. Other common symptoms
include:
Cold Fingers / Cold Hands: Persistent coldness in the extremities, even in mild temperatures,
can be a daily struggle for those with Raynaud’s.
Numbness or Tingling: As blood flow is restricted, you may experience numbness or
tingling in the affected areas.
Pain: The constriction of blood vessels can lead to pain in the fingers or toes, especially when
they start to regain circulation.
Skin Changes: Over time, individuals with Raynaud’s may notice skin changes, including
thickening of the skin, ulcerations, or in severe cases, gangrene.
Sensitivity to Cold: Individuals with Raynaud’s may need to take extra precautions in cold
weather, wearing multiple layers of clothing and gloves to minimize the risk of an attack.
3. Emotional Stress Triggers: Emotional stress and anxiety can also trigger Raynaud’s attacks,
making it more than just a cold weather concern.
Diagnosing Raynaud’s Phenomenon
If you suspect you have Raynaud’s phenomenon due to persistent and severe symptoms, it’s
essential to seek medical attention. Your healthcare provider will typically conduct a physical
examination and take your medical history. They may perform additional tests to differentiate
between primary and secondary Raynaud’s and rule out other potential causes of your symptoms.
Some diagnostic tests may include:
Nailfold Capillaroscopy: This test involves examining the nailbed’s capillaries under a
microscope to detect abnormalities associated with autoimmune disorders.
Blood Tests: Blood tests can help identify underlying conditions that might be contributing to
Raynaud’s symptoms.
Cold Stimulation Test: In this test, the doctor immerses the patient’s hands or feet in cold
water and observes their response, looking for changes in skin color or other abnormal
reactions.
Managing Raynaud’s Phenomenon
While there’s no cure for Raynaud’s phenomenon, there are various strategies to help manage and
alleviate its symptoms:
Avoid Cold Exposure: Dress warmly, wear gloves and thermal socks, and limit exposure to
cold temperatures.
Stress Management: Reducing stress and anxiety can minimize Raynaud’s attacks.
Medications: In severe cases, doctors may prescribe medications to relax blood vessels and
improve blood circulation.
4. Biofeedback: This technique can help individuals gain control over their body’s response to
stress and cold.
Quit Smoking: Smoking can exacerbate Raynaud’s symptoms by constricting blood vessels.
Quitting can be immensely beneficial.
Stay Active: Regular physical activity helps promote better blood circulation.
Avoid Triggers: Identify and avoid specific triggers that provoke Raynaud’s attacks, whether
they are certain medications, chemicals, or lifestyle factors.
Medical Intervention: In severe cases, medical interventions like nerve surgery or chemical
injections can be considered.
Living with Raynaud’s Phenomenon
Living with Raynaud requires patience, lifestyle adjustments, and ongoing management. The key
to managing this condition effectively is understanding its triggers and learning how to avoid
them. By following a comprehensive treatment plan and making necessary lifestyle changes,
individuals with Raynaud’s can minimize the frequency and severity of attacks and continue to
lead fulfilling lives.
In conclusion, cold hands might be more than a normal reaction to chilly weather; it could be a
sign of Raynaud’s phenomenon. Understanding this condition, its causes, symptoms, diagnosis,
and management options is crucial for individuals who experience these symptoms. If you
suspect you have Raynaud’s, consult with a healthcare professional to get the appropriate
diagnosis and guidance for managing this condition effectively. Remember, you are not alone,
and there are strategies and treatments to help you live well with Raynaud’s phenomenon and feel
some warmth, after all, who likes cold hands?
