Helping Prevent Pressure Ulcers

Pressure UlcerAccording to the National Pressure Ulcer Advisory Panel (NPUAP), a pressure ulcer is “localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in combination with shear and/or friction”.

Pressure ulcers (also known as bed sores or pressure sores) are a serious issue affecting the quality of life for many individuals with various health complications in different settings including living at home.

Pressure ulcers are a complex healthcare problem with multiple causes.  They are not a new phenomenon since their occurrence was recorded beginning in 2050 BC.  In addition, the early physician, Hippocrates, documented pressure ulcers in 400 BC.  Today, pressure ulcers are a substantial clinical, economic, regulatory and legal problem for healthcare providers and patients.  In fact, it has been estimated that treating pressure ulcers cost the U.S. at least 11 billion dollars per year.

For high-risk populations including critically ill patients, a cumulative incidence of at least 15% has been reported for category 2 or higher pressure ulcers.  There are also many factors that increase the risk for pressure ulcers including advanced age, malnutrition, immobility, loss of consciousness or cognitive abilities, inability to feel pain, decreased blood flow due to diabetes or peripheral arterial disease, as well as dry skin and skin maceration that makes skin more vulnerable to damage.

Increasing Hydration and Protecting Macerated Skin

Senior woman in wheel chairViniferamine® Renewal Moisturizer and Viniferamine® SkinMineralZ contain important skin nutrients including antioxidants, amino acids and vitamins to strengthen vulnerable skin. Renewal Moisturizer increases skin hydration to help keep moisture in skin, as well as ensure proper nourishment of the epidermis.  Each ingredient in Renewal Moisturizer has been perfectly pH balanced.  SkinMineralZ helps nourish macerated, inflamed skin while providing absorption of toxins.  The micronized zinc oxide in SkinMineralZ is ideal for treating delicate skin that cannot tolerate abrasiveness.

Pressure is the amount of force applied perpendicular to a surface area.  In addition, forces known as shear forces may be applied parallel to a skin surface.  Shear forces are commonly applied when patients slide down a surface and they typically affects the sacrum and heel areas of skin.  When pressure is applied to skin, especially over bony prominences, it distorts the skin and underlying soft tissues.  If constant pressure is maintained, soft tissue will change and mold itself to accommodate the external shape, referred to as tissue creep.  Blood vessels within the distorted tissue become compressed, bent or stretched out of their normal shape such that blood cannot flow which results in the tissues supplied by these vessels becoming ischemic.

Changing Positions and Strengthening the Skin Barrier

Normally, reflexive movements relieve tissue distortions, or the central nervous system is stimulated producing pain that causes movement to relieve pressure and distortion before serious damage occurs.  In fact, healthy individuals (that have normal sensation) change positions in their sleep every 11.6 minutes on average.

Young man asleepWhen the circulation is restored, local capillaries dilate and blood flow increases resulting in reactive hyperemia.  This appears as a bright pink blanchable (capable of whitening) patch on the skin.  When the erythema (redness) is unblanchable, that indicates tissue damage characteristic of category 1 pressure ulcers has occurred.

Therefore, there are 3 main causes of pressure ulcers: immobility, failure of reactive hyperemia and loss of sensation.  Pain is an early warning sign for pressure damage and the use of strong pain medicines may delay triggers for movement.  Distortion of soft tissues is particularly dangerous for paraplegic patients.  If ischemia persists, pressure ulcers can occur within 2 hours.  Patients who experience sudden drops in blood pressure due to events such as cardiac arrest may also be at risk for pressure ulcers.  Prolonged pressure can result in skin atrophy and thinning of the protective skin barrier.

Viniferamine® skincare products include ingredients that strengthen skin and improve the skin barrier. Quantitating transepidermal water loss (TEWL) is a way to assess the quality of the skin barrier and how well it functions.  Oleuropein has been shown to reduce TEWL indicating its ability to increase skin barrier function.  Evidence also demonstrates that melatonin has a stimulatory role in building and maintaining the epidermal barrier.

Besides implementing optimal skin care provided by Viniferamine® skin and wound care products, there are other steps that can be taken to reduce the risk of pressure ulcers.  It’s important to reposition patients that are immobilized.  Pressure redistribution support surfaces are also useful.  Patients that cannot move need to be advised to report pain to someone who can help them reposition.  It’s important to be aware of the fact that a source of pain in another location may distract an individual from the pain associated with pressure, reducing the likelihood that the individual will respond to the pain trigger.

It’s good to know that Viniferamine® skincare products include ingredients to decrease inflammation, nourish and strengthen skin, and protect and hydrate skin.  SkinMineralZ helps protect macerated skin to decrease the risk of pressure ulcers and Renewal Moisturizer helps eliminate dry skin, which also decreases the risk of pressure ulcers.

Helping Prevent Fragile Skin Bruising

Fragile skin bruising arm image

As the number of individuals living longer rises, the prevalence of certain skin issues experienced by older individuals, such as fragile skin bruising, is increasing.

Fragile skin bruising or senile purpura (sometimes called solar purpura) is a common skin disorder that occurs with at least 10% of individuals over the age of 50, and 29% of elderly individuals.

Although the bruising is typically not painful it can be fairly irritating. Moreover, fragile skin bruising is highly visible and is likely to have a significant psychological impact. Fragile skin bruising appears as red or purple spots or patches in the skin that fade to brown. It is characterized by hemorrhages in the skin due to vascular fragility, trauma, or deficient coagulation. The bruises are commonly associated with skin tears and can result from very minor trauma including bumping into fairly soft objects.

Reducing Sun Damage to Skin

SunshineThe sun is a powerful source of energy and radiation that can be both beneficial and harmful.  It feels so great to get out in the sun, especially after a cold, rainy day, but the effects of too much sun can be incredibly damaging to skin health.  The sunlight’s cellular and molecular effects depend on the radiation energy and penetration.  The spectrum of solar radiation ranges from the shorter wavelengths of UVB and UVA to the longer wavelengths of visible radiation (VIS), near-infrared radiation (NIR) and infrared radiation (IR).  UV radiation has more energy and is more penetrating.  UVB radiation has more energy than UVA radiation.

UVA exposure, however, causes accelerated skin aging known as photoaging or extrinsic aging (as opposed to normal or instrinsic aging).  Photo-aged skin is characterized by deep wrinkling, loss of elasticity, uneven pigmentation, dryness, and rough texture.  The UV-induced degeneration of skin is a cumulative process that depends on the frequency, duration and intensity of exposure, as well as skin pigmentation.  UV radiation and NIR radiation both give rise to the generation of reactive oxygen species (ROS).  ROS play an important role in skin aging due to the fact that aged skin has a decreased ability to neutralize ROS leading to increased oxidative stress.

 Avoiding Hand Dermatitis

Hand dermatitis is one of the most common problems encountered in dermatology with a prevalence possibly as high as 50% hand dermatitisor greater in certain occupations. The dis­comfort associated with hand der­matitis frequently results in a de­creased quality of life. In fact, hand dermatitis can be debilitating for many years.

Dermatitis (or eczema) is inflam­mation of the skin, characterized by itchy (pruritic), red, weeping skin with vesicles and/or crusty patches. The risk factors for hand dermatitis include chemical expo­sures, frequent handwashing, and wet-work environments contribut­ing to a higher prevalence in specif­ic occupations including healthcare professionals, machinists, hair­dressers, and food industry em­ployees.

 Reducing Dermal Scarring

Scars are areas of dermal fibrosis that replaces normal tissue after in­jury and during wound healing.

There are several types of dermal scars including:

  1. Atrophic scars that appear as sunken or pitted areas of skin
  2. Hypertophic scars that are charac­terized by raised areas of skin
  3. Keloid scars characterized by growth outside the original wound area
  4. Striae distensae (stretch marks) characterized by linear bands of atrophic-appearing skin.

Dermal ScarringWound healing involves 4 critical phases that overlap: the coagulation phase, the inflammatory phase, the migration-proliferation phase (de­velopment of granulation tissue), and the remodeling-regeneration phase that includes maturation, scar formation and re-epithelialization. The magnitude of the second phase, inflammation, affects the amount of scar tissue that is produced at the conclusion of the healing process. Regeneration is thought of as re­placement of tissue, however, scar formation actually involves a pro­gressive remodeling of granulation tissue. In fact, scars are defined as dermal fibrous replacement tissue that results from a wound that has healed by resolution (rather than re­generation).

Scarring typically occurs following damage to more than 33% of the skin thickness from trauma or surgery. Can skin damaged in this way ever heal without scarring? Actually, com­plete regeneration occurs exclusively in lower vertebrates. Scarless heal­ing in humans only occurs in early embryo development. So, why do we form scars after early development? One theory suggests that wound healing in mammals is optimized for fast healing in a fast-moving, micro­bial-rich environment. Rapid inflam­matory responses may allow quick healing to prevent infections. Continue reading

Protecting Mitochondria for Skin Health

Mitochondria are organelles found in the body’s cells (including skin cells) that generate energy in the form of ATP.  They are known as the powerhouses of cells due to this important function.  Interestingly, they are thought to originate from bacteria-related cells because of their striking similarity to bacteria (including mitochondrial DNA that is very similar to bacterial DNA) and the belief that they appear to have developed a symbiotic relationship with higher order cells, such as mammalian cells.

In addition to generating energy, mitochondria play critical roles in other cellular processes including:

  1. The production of reactive oxygen species (ROS)
  2. The regulation of cellular metabolism
  3. Calcium signaling
  4. Programmed cell death (apoptosis)
  5. Inflammation
  6. Wound healing

Antioxidants and Skin Health

The skin is the largest organ of the body and is the first line of defense against balancing rocksvarious external threats including temperature
changes, dehydration, invading microbes, harmful chemicals, pollution, and ionizing radiation. These threats are potentially damaging because they can alter biological homeo­stasis (or the maintenance and regulation of stability required for proper functioning).

One very important aspect of skin homeostasis involves maintain­ing the balance between the pro­duction of free radicals, known as reactive oxygen species (ROS), and the skin’s oxidative defense system. Toxic chemicals, pollu­tion (including cigarette smoke), ionizing radiation (including UV), and extreme temperature change can all cause elevated ROS that may disrupt this balance, poten­tially leading to oxidative stress, skin inflammation, increased ag­ing and disease.

Fight Cancer With Sleep

Sleeping womanMost people would agree that nothing really beats a great night of restful sleep. Most cells in your body would also agree that they appreciate a good nights rest. However, there are certain types of cells in your body that cannot stand it when you get a full night of great sleep – and those are cancer cells.

We know that sleep is important for feeling rested and energetic during the day, improving mood, immunity, work performance, heart health, cognition – more things than can possibly be imagined. But would you believe that the quality and amount of sleep you get could actually change the way your body responds to certain medications? In fact, as in the case of the breast cancer drug tamoxifen, it could be the difference in treatment success or failure. Continue reading

Scientific Ingredients in Viniferamine

Screen Shot 2014-03-14 at 10.38.27 AMEach of the ingredients used in the Viniferamine products was selected based upon its purity, efficacy and scientific worthiness. Within the selection process a few ingredients were so critical to the product’s performance, we decided to call special attention to them.

The skin is an incredibly complex organ and our very survival is reliant upon its ability to protect us. Its continuum of cell turnover is dependent on essential nutrients used in the production of collagen and hyaluronic acid. The exact balance of collagen proteins and hyaluronic acid sets the stage for skin healing or conversely the skin failure.

Two of the scientific ingredients featured here have been scientifically proven to produce the levels of collagen necessary for skin restructuring while protecting the vital level of hyaluronic acid. Titrated Extract of Centella Asiatica is involved in the production of skin collagens required for tissue repair and healing. Dipotassium Glycyrrhizinate protects hyaluronic acid (cell-migration signaling molecule) by inhibiting the enzyme that destroys this vital glycosaminoglycan.

Viniferamine products create an entirely new level of skin repair, fully supported by science.
