Diabetes pens are an alternative way of injecting insulin that have been used around the world for years and are slowly catching on in the United States.
To use an insulin pen, a person sets the amount of insulin they need, usually by turning a dial, attaches a new needle, inserts the needle under the skin, presses a button to inject the insulin and holds the needle in place for five seconds before removing it. The one major disadvantage of insulin pens is they do not allow mixing different types of insulin, so people using more than one type of insulin may need to double the number of injections they have. A few companies make special diabetes pens for children that come in bright colors and fun designs, such as the NovoPen Junior, a refillable diabetes pen made by Novo Nordisk.
Insurance coverage for diabetes pens varies widely in the United States with some companies covering them just like syringes and vials, and other insurance policies not covering them at all.

Cardiovascular disease is the leading cause of death in patients with chronic kidney disease.  Heart failure may lead to acute kidney injury and vice versa. The case below illustrates a common clinical problem in patients with both acute and chronic cardiac diseases, namely the development of renal dysfunction. A 68-year-old man with ischemic heart disease, type 2 diabetes mellitus, hypertension, and hyperlipidemia had been admitted with a ST segment elevation myocardial infarction three months previously.
The term cardiorenal syndrome is an umbrella term for a worse outcome when these two organs fail simultaneously. The development of acute kidney injury as a primary event leading to cardiac dysfunction (CRS type 3) occurs frequently in critically ill patients but has not been systematically studied as much as CRS type 1. CRS type 4 recognizes the extreme burden of cardiovascular disease risk in patients with chronic kidney disease.
Human neutrophil gelatinase- associated lipocalin (NGAL), Kidney injury molecule-1 (KIM-1), N-acetyl-D-glucosaminidase (NAG), Ischemia modified albumin (IMA), Renin-angiotensin-aldosteronesystem(RAAS), Sympathetic nervous system(SNS), Myocardial depressant substance (MDS), Brain natriuretic peptide (BNP), N-terminal pro hormone of brain natriuretic peptide (NT-proBNP) , Interleukin-18(IL-18), creatine kinase –MB (CK-MB), Myeloperoxidase (MPO), Pulmonary vasoconstriction (Pulmonary VC), glomerular filtration rate(GFR). CRS type 1 is the most frequent disorder involving the heart and the kidney and is more frequent in patients with acute decompensated heart failure. Prevention of CRS is important since once the syndrome has started it is difficult to treat, is not completely reversible in some cases, and is associated with poor outcomes. For CRS type 2 angiotensin converting enzyme inhibitors, beta-blockers, angiotensin receptor blockers, and aldosterone antagonists significantly reduce mortality and morbidity in congestive heart failure.41,42 In patients unable to tolerate these agents, hydralazine and nitrates can be used. The development of dysfunction in a second organ (renal) as a consequence of the primary disorder (cardiac) increases morbidity and mortality. The cardiorenal syndrome classification may help clinicians organize their thinking about pathogenesis and patient management.

To fully understand metabolic syndrome, it is first important to have a basic understanding of normal energy consumption, storage and usage in the human body. Following postprandial increase in blood glucose levels, the pancreas releases insulin into the body.
Insulin binds to the cell through an insulin receptor, which consists of two extracellular ? subunits and two transmembrane ? subunits. Obesity is defined as excessive fat content in the adipose tissue stores resulting in a bodyweight that is greater than 20% when compared to normal standards. One of the fundamental aspects of metabolic syndrome is the relationship between the disease and increased waist circumference. The degree to which metabolic syndrome is caused by genetic factors is under debate, with heritability ranging from approximately 25-60%. Multiple processes have been researched to describe the genetic influence on metabolic syndrome and many hypotheses have been developed.
There are many other genetic factors that can contribute to obesity and all of the other factors associated with metabolic syndrome. Maternal diabetes produces an increased risk to their offspring of not only developing diabetes, but also increases their susceptibility to obesity.[25] Intrauterine exposure to higher amounts of glucose occurs in diabetic mothers because glucose is able to freely cross the placenta, while insulin does not. Epigenetics, which means inheritance of information based on gene expression rather than gene sequence, may have links to the maternal influences to the development of metabolic syndrome.
While genetics and maternal influences can play a role in the development of metabolic syndrome, environmental factors also play a substantial role. Several other factors have been shown to be linked to insulin sensitivity and metabolic syndrome. The dyslipidemia most commonly associated with metabolic syndrome is labeled hypertriglyceridemia.
Nonalcoholic fatty liver disease (NAFLD) is a term used to describe a condition of fat accumulation in the liver in the absence of excessive alcohol consumption.[18,39,40] NAFLD is more frequent in obese subjects (75%) compared with controls (16%) and among patients with type 2 diabetes (34-74%).
Decreases in mitochondrial biogenesis have been associated with obesity and type II diabetic mice.[46, 47] Kelley et al.
Subsarcolemmal mitochondria generate the ATP necessary for membrane processes such as fatty acid oxidation, insulin signaling, glucose transport, and ion exchange.
Boudina et al.[49] examined the effects of impaired mitochondrial function on ATP production and cardiac efficiency in mouse hearts. Nuclear respiratory factor-1 (NRF-1) is a regulator of mitochondrial genes, including mitochondrial transcription factor A (Tfam) and the genes of oxidative phosphorylation.[44,53] PGC-1? expression regulates NRF-1 expression.
ATM (ataxia telangiectasia mutated) protein is required for DNA repair and to maintain genomic homeostasis.
When the PERK pathway is activated, selective suppression of protein translation occurs, causing an increase in expression of many genes involved in apoptosis.[56] When ATF-6 is activated, it translocates to the nucleus and increases the expression of protein chaperones, ER degradation-enhancing ?-mannosidase-like protein (EDEM) and X-box protein 1 (XBP-1), thereby increasing ER biogenesis and secretion. The oxidative stress from accumulated fat has been found to be an important factor in metabolic syndrome primarily through the dysregulation of adipocytokines. A study in which the gene that encodes for adiponectin was disrupted in mice ( known as ACR3P0 knockout mice or KO mice) found that adiponectin deficiency and high TNF-? levels reduced muscle fatty-acid transport protein 1 (FATP-1) mRNA and insulin-receptor substrate 1 (IRS-1) mediated insulin signaling, which resulted in severe diet-induced insulin resistance.[71] These findings suggest that adiponectin accelerates FFA clearance and fatty-acid oxygenation.
Besides adiponectin's important role in insulin sensitivity, it also plays an important role in the prevention of atherosclerosis and cardiovascular disease. The Islands of langerhans secrete four hormones insulin, glucagon, somatostatin and pancreatic polypetide. It is secreted in response to a fall in the blood glucose level by the alphacell of the Islets of langerhans Its action is opposite to that of insulin. The endocrine gland attached to the roof of third ventricle in the rear portion of brain, is known as the pineal gland, named for its resemblance to a pine cone.
Background? The term of acquired perforating dermatosis (APD) comprises the perforating dermatoses occurring in adult patients.
Objective? The aim of this study was to delineate the clinical and histopathological features of acquired perforating dermatosis and to investigate the potential relationship between this disease and associated conditions. Results? Different clinical types of lesions resembling reactive perforating collagenosis, perforating folliculitis or Kyrle's disease were observed. Conclusion? Clinicopathological findings of our study indicate that the cases with APD represent the broad spectrum of perforating disorders rather than the variants of the same disease. The pens allow more accurate dosing, they are easier to carry in a purse or pocket, they can be used discretely, and are easier to use for people with motor control problems or poor eyesight.
However, manufacturers are addressing the problem, and some companies are offering diabetes pens that have mixed insulin in the reservoir. Chronic kidney disease may affect the clinical outcomes in patients with cardiovascular disorders. This clinical presentation has been called a cardiorenal syndrome; this construct should lead to a better understanding of the interactions between cardiac and renal disorders and the effect of this interaction on management and outcomes.
At this follow up visit he presented with gradually increasing shortness of breath, generalized swelling, and some abdominal distension. Since the current literature provides more information on CRS type 1, our discussion emphasizes this syndrome. Although CRS is less frequent in acute coronary syndrome patients, it is associated with longer hospital stays and with higher in-hospital mortality in these patients.


Vasodilators and loop diuretics are frequently used in cases of acute decompensated heart failure with CRS type 1.36 However, loop diuretics predispose patients to electrolyte imbalance and hypovolemia leading to neurohumoral activation, reduced renal glomerular flow, and higher serum urea and creatinine levels. The Study of Heart and Renal Protection (SHARP) trial included 3,023 end stage renal disease patients and 6,247 chronic kidney disease patients not on dialysis, and preliminary results showed a significant benefit with the combination of simvastatin and ezetimibe.46 In another study, 245 patients were randomized to three times weekly (conventional) or six times weekly (frequent) hemodialysis and followed up for 12 months.

To begin, the human body maintains cellular function by means of consuming energy via the foods we eat. Brown adipose tissue’s primary role is in non-shivering thermogenesis and is found in much lesser quantities in humans.[8] White adipose tissue is the site of energy storage and neuroendocrine effects. The beta cells of the pancreas produce the hormone insulin, which acts on skeletal muscles, liver and adipose tissue.
The definition of metabolic syndrome was created with the use of waist circumference as a measure for obesity, not using Body Mass Index, a very popular measure to quantify obesity.
Evidence suggests that if extra energy was stored in insulin-sensitive subcutaneous adipose tissue, the individual would be protected from possibly developing metabolic syndrome. A major component of the genetic influence resides in the mitochondria where expression of peroxisome proliferator-activated receptor (PPAR) gamma coactivator (PGC-1) is decreased. They continue to be researched and the chart below is a list of some of the genes associated with increased obesity. In the fetus this causes an increase in secretion of insulin, which acts as a fetal growth hormone encouraging growth and increased adipocyte development.
Alcohol intake is also thought to play a role in insulin sensitivity; it is thought to be beneficial to insulin sensitivity as long as it is ingested moderately. The mechanisms explaining this phenomena is largely theoretical at this point, though evidence suggests that smaller LDL particles can more easily penetrate the arterial endothelium and gain entry into the subendothelial space where they are more easily oxidized. It is also found in children, particularly obese children (38%) and children with type 2 diabetes (48%).[39] The pathogenesis of NAFLD combines many of the topics outlined throughout this page. In obese mouse with partially or fully abolished TNF-? receptors, a restoration in eNOS mRNA and proteins, PGC-1?, NRF-1, and Tfam levels was demonstrated. Ritov at al.[50] demonstrated that individuals with obesity and DMII have significantly less subsarcolemmal mitochondria than lean individuals, with DMII greater reductions than obesity. PGC-1? was significantly reduced in patients with DM and non-diabetic patients with a positive family history for DM compared to controls. When the number of nutrients reaches a pathological level, the ER activates the unfolded protein response (UPR). When there are too many proteins, there is not enough BiP to bind the stress-sensing proteins. Increased fat accumulation has been correlated with systemic oxidative stress in humans and mice. Adiponectin downregulates vascular adhesion molecules and inhibits smooth muscle migration and foam cell formation, which can be seen in the image below.[77] As discussed earlier, adiponectin levels are decreased in obesity, so it can be seen how the risk of cardiovascular disease and the presence of hypertension found in metabolic syndrome are related to adiponectin levels. It brings about change of liver glycogen to blood glucose, to provide energy between meals. It decreases the rate of nutrient absorption into the blood stream from the gastrointestinal tract and inhibits the secretion of insulin and glucagon.
Clinical and histological features of the disease are not uniform, and may resemble any of the four classic perforating disorders: elastosis perforans serpiginosa, reactive perforating collagenosis, perforating folliculitis or Kyrle's disease. Clinical findings of acquired perforating dermatosis and the spectrum of associated diseases were investigated.
Histopathological features were consistent with any of the four types of perforating dermatoses. Although APD is frequently associated with diabetes mellitus and chronic renal failure, this skin disorder may also develop in patients with other systemic disorders, and in those without any medical problems.
Disposable pens have their reservoir built in and the whole pen is thrown out and replaced when it runs out of insulin.
Renal impairment with any degree of albuminuria has been increasingly recognized as an independent risk factor for cardiovascular events and heart failure hospitalizations, while chronic heart failure may cause chronic kidney disease.
We have reviewed this topic by discussing the definitions, prevalence, pathophysiology, and treatment of cardiorenal syndromes. Both acute heart failure leading to acute kidney injury and chronic heart failure leading to progressive renal insufficiency and chronic kidney disease represent conditions that may seem interchangeable.
Depending upon pre-existing comorbidity and the underlying etiology, left ventricular assist devices can be used as a bridge to transplantation or cardiac surgery. The core management of CRS type 3 is intravascular and extravascular volume control with either use of diuretics and various forms of renal replacement therapy or extracorporeal therapy and solute removal. For example, removal of the source of infection, antibiotic therapy, and other supportive measures in early goal directed therapy are indicated in patients with septic CRS type 5.


Cardiac resynchronization therapy with biventricular pacing improves renal function in heart failure patients with reduced glomerular filtration rate.
This leads to a reduction of oxidative phosphorylation by 30% as the mitochondria are smaller and less efficient without PGC-1, which results in increased levels of triglycerides. The combination of these traits is often present in metabolic syndrome and therefore this single genetic defect could be a link to the development of metabolic syndrome.
This receptor helps to fight infection, but it also helps to develop hyperlipidemia, hypertension, insulin resistance, and increased adiposity. One example of this is protein restriction during the fetal development period in a study on rats. Insulin sensitivity can be influenced not only by total energy intake but also by the composition of the diet. The renin release from the kidneys and the formation of Ang II is then stopped by sodium retention and increased extracellular fluid. This finding significantly correlated with increased insulin sensitivity as measured by glucose disposal rate.
Therefore, TNF-? was shown to downregulate eNOS, thereby resulting in decreased mitochondrial biogenesis. They also found that the decreased in ETC activity was not proportional to the decrease in sarcolemmal mitochondria in those with DMII and obesity.[50] This may implicate subsarcolemmal mitochondria in a possible mechanism for insulin resistance. The study also showed that UCP-DTA mice have increased PPAR-?, which in turn increased PGC-1?, NRF-1, and TFAM. It is variable in size and weighs about 150 mg, but it is richly vascularised and secretes several hormones, including melatonin. Haematoxylin and eosin sections were re-examined, and immunohistochemical stainings (elastic van Gieson and Masson trichrome stains) and periodic acid-Schiff stain were also used for histopathological evaluation. This skin disease is probably linked to dialysis treatment in patients with chronic renal failure due to diabetes mellitus or other causes. The bidirectional nature of these disorders contributes to the complexity and the composite definitions of cardiorenal syndromes.
In some cases it difficult to distinguish between the two entities without the necessary time based information in the clinical history of the patient. Aronson et al reported that persistent worsening renal function after admission for acute decompensated heart failure was more likely in those with worse baseline kidney function. In a randomized trial involving patients hospitalized for acute decompensated heart failure, worsening renal function, and persistent congestion, Bradley found that a stepped pharmacologic-therapy algorithm was superior to ultrafiltration for the preservation of renal function. In the setting of acute kidney, prevention of left ventricular volume overload is critical to maintain adequate cardiac output and systemic perfusion and also to protect against the vicious cycle that will worsen both cardiac and renal function. Important improvements in serum phosphate, control of hypertension, and avoidance of intradialytic hypotension were also noted in the frequent dialysis group.
Adipose tissue can be stored as either subcutaneous fat or visceral fat, surrounding the organs in the thorax including the liver and heart. Carnitine palmotransferase-1 (CPT-1) is required to transport triglycerides into the mitochondria.
Vijay-Kumar et al found that transferring the gut microbiota from TLR5-deficient mice to wild-type germ-free mice developed many of the features of metabolic syndrome.[23] They also found that food restriction prevented obesity in these mice, but did not help to prevent insulin resistance, leading to a stronger link between TLR5 and diabetes. A reduction in proteins increased the rate of apoptosis of pancreatic ?-cells, resulting in a small mass of ?-cells in their offspring; thus increasing the risk of ?-cell dysfunction. The most recognized components of diet studied in regard to metabolic system are the fat content, especially unsaturated vs. The increased oxygen consumption, however, did not result in an increase in ATP production, revealing a decreased cardiac efficiency in fatty acid metabolism. In Furukawa et al.’s study cultured adipocytes increased levels of FFA increased oxidative stress via NADPH oxidase activation and this caused dysregulated production of adipocytokines including adiponectin, PAI-1, and IL-6. In humans, it has no lightsensitive cells, like lower vertebrates, where pineal is eye-like and responds to light. Chronic renal failure (72.7%) and diabetes mellitus (50%) were the most commonly associated conditions.
However, the most important clinical trials in heart failure tend to exclude patients with significant renal dysfunction. The pathophysiology of CRS type 1, renal dysfunction in patients with decompensated heart failure, is complex. Untreated uremia affects myocardial contractility through the accumulation of myocardial depressant factors and can cause pericarditis.17 Partially corrected or uncorrected acidemia produces pulmonary vasoconstriction, which in some patients contributes to right-sided heart failure. He investigated this outcome in a cohort of 467 patients admitted with acute decompensated heart failure.
Weight loss at 96 hours was similar with the two approaches, but ultrafiltration was associated with higher rates of adverse events.38 An earlier ultrafiltration vs. In the PI3K pathway, IRS that have been tyrosine-phosphorylated interact with the p85 subnit of PI3K, resulting in the synthesis of PIP3 (phosphatidlinotilol 3,4,5 phosphate).
In the presence of insulin resistance, the activity of CPT-1 is decreased, which causes an increase of triglycerides in the cytoplasm. Boudina et al.[49] concluded that fatty acid induced uncoupling was the cause for decreased cardiac efficiency in obese mice, the results of which were confirmed by other researchers. When NADPH oxidase inhibitor was used in obese mice, ROS were reduced, which resulted in decreased dysregulation of adipocytokines and improved diabetes, and hyperlipidemia.[66] The roles of each adipocytokines are explained in greater detail below. Blood cholesterol rises, healing power is impaired so that injuries may change into gangrenes. Pineal gland functions as a biological clock and a neurosecretory transducer, converting neural information. Most of the patients with diabetes mellitus (90.9%) had chronic renal failure due to diabetic nephropathy. Optimization of fluid, avoidance of nephrotoxic agents, and correction of underlying disorders are the basic principles.
Once thought to be merely a storage site for fat cells, adipocytes have been found to have many endocrine functions as well, which will be discussed in detail.
Not only the amount of carbohydrates but also the speed at which they are broken down plays a role in avoiding the problems of a high-carbohydrate diet. The diabetic person has blurred vision and is weak, tired, irritable, nauseated and underweight.
The hypovolemia leads to sympathetic activity, increased renin-angiotensin-aldosterone pathway, and arginine-vasopressin release. Downstream PIP3 is responsible for the activation of PDK (phosphoinsitide dependent kinase) and Akt (protein kinase 3). Its formation is interrupted when light enters the eyes and stimulates the retinal neurons. These mechanisms cause fluid and sodium retention, peripheral vasoconstriction, and volume overload. These markers reflect activation of hormonal, immunologic, inflammatory, and oxidative processes and are associated with an increased risk deterioration in renal function.15,16 These biomarkers have the potential to identify cardiorenal syndromes and predict outcomes and need more study.
This trial showed that ultrafiltration produces greater weight and fluid loss than intravenous diuretics and reduces 90-day heart failure rehospitalizations and emergency department visits in patients with acute decompensated heart failure. Thus, the major site for energy storage in the body is in fat cells, or adipocytes, that compose adipose tissue. Therapy to improve renal dysfunction, reduce neurohormonal activation and ameliorate renal blood flow could lead to a reduction in mortality and hospitalization in patients with cardiorenal syndrome.
Patients with chronic heart failure can develop chronic renal failure (CRS type2) through a similar pathophysiology. These results support the hypothesis that removal of isotonic fluid by ultrafiltration rather than hypotonic urine by intravenous diuretics may explain the improved clinical benefits of ultrafiltration.40 However, ultrafiltration increases the complexity of care. Akt’s role related to insulin includes glucose transport and storage, protein synthesis and stopping lipid degradation.
