Stem cells are undifferentiated cells with the ability of proliferation, regeneration, conversion to differentiated cells and producing various tissues. Stem cells are divided into two categories of embryonic and adult. In another categorization stem cells are divided to Totipotent, Multipotent and Unipotent cells.So far usage of stem cells in treatment of various blood diseases has been studied (such as lymphoblastic leukemia, myeloid leukemia, thalassemia, multiple myeloma and cycle cell anemia). In this paper the goal is evaluation of cell therapy in treatment of Parkinson's disease, Amyotrophic lateral sclerosis, Alzheimer, Stroke, Spinal Cord Injury, Multiple Sclerosis, Radiation Induced Intestinal Injury, Inflammatory Bowel Disease, Liver Disease, Duchenne Muscular Dystrophy, Diabetes, Heart Disease, Bone Disease, Renal Disease, Chronic Wounds, Graft-Versus-Host Disease, Sepsis and Respiratory diseases. It should be mentioned that some disease that are the target of cell therapy are discussed in this article.

Mycoplasma pneumoniae is one of the most common agents causing respiratory disease in children. The most common extra-pulmonary manifestations of M. pneumoniae include central nervous system involvement, with stroke being an uncommon but devastating consequence. We present a 13-year-old girl with severe respiratory disease requiring extracorporeal membrane oxygenation, who developed ischemic stroke associated with clinical and serologic evidence of M. pneumoniae. A case of M. pneumoniae causing this degree of respiratory failure associated with stroke has not been previously reported. Prompt recognition of severe mycoplasmal infection may allow for earlier treatment and concomitant evaluation of neurologic injury.

The positive associations between education and health and survival are well established, but whether the strength of these associations depends on gender is not. Is the beneficial influence of education on survival and on self-rated health conditioned by gender in the same way, in opposite ways, or not at all? Because women are otherwise disadvantaged in socioeconomic resources that are inputs to health, their health and survival may depend more on education than will men's. To test this hypothesis, we use data from the National Health Interview Survey-Linked Mortality Files (NHIS-LMF). We find that education's beneficial influence on feeling healthy and on survival are conditional on gender, but in opposite ways. Education has a larger effect on women's self-rated health than on men's, but a larger effect on men's mortality. To further examine the mortality results, we examine specific causes of death. We find that the conditional effect is largest for deaths from lung cancer, respiratory disease, stroke, homicide, suicide, and accidents. Because women report worse health but men's mortality is higher, education closes the gender gap in both health and mortality.

Changes in health behaviours (smoking, physical activity, alcohol consumption, and fruit and vegetable consumption) after diagnosis of chronic health conditions (heart disease, cancer, stroke, respiratory disease, and diabetes) were examined among Canadians aged 50 or older. Results from 12 years of longitudinal data from the Canadian National Population Health Survey indicated relatively modest changes in behaviour. Although significant decreases in smoking were observed among all groups except those with respiratory disease, at least 75% of smokers did not quit. No significant changes emerged in the percentage meeting physical activity recommendations, except those with diabetes, or in excessive alcohol consumption, except those with diabetes and respiratory disease. The percentage reporting the recommended minimum fruit and vegetable intake did not increase significantly among any group.

Geographic variations in mortality rate in the United States could be due to several hypothesized factors, one of which is exposure to solar ultraviolet radiation (UVR). Limited evidence from previous prospective studies has been inconclusive. The association between ambient residential UVR exposure and total and cause-specific mortality risks in a regionally diverse cohort (346,615 white, non-Hispanic subjects, 50-71 years of age, in the National Institutes of Health (NIH)-AARP Diet and Health Study) was assessed, with accounting for individual-level confounders. UVR exposure (averaged for 1978-1993 and 1996-2005) from NASA's Total Ozone Mapping Spectrometer was linked to the US Census Bureau 2000 census tract of participants' baseline residence. Multivariate-adjusted Cox proportional-hazards models were used to estimate hazard ratios and 95% confidence intervals. Over 12 years, UVR exposure was associated with total deaths (n = 41,425; hazard ratio for highest vs. lowest quartiles (HRQ4 vs. Q1) = 1.06, 95% confidence interval (CI): 1.03, 1.09; Ptrend < 0.001) and with deaths (all Ptrend < 0.05) due to cancer (HRQ4 vs. Q1 = 1.06, 95% CI: 1.02, 1.11), cardiovascular disease (HRQ4 vs. Q1 = 1.06, 95% CI: 1.00, 1.12), respiratory disease (HRQ4 vs. Q1 = 1.37, 95% CI: 1.21, 1.55), and stroke (HRQ4 vs. Q1 = 1.16, 95% CI: 1.01, 1.33) but not with deaths due to injury, diabetes, or infectious disease. These results suggest that UVR exposure might not be beneficial for longevity.

Chronic non-communicable diseases such as heart disease, cancer and diabetes are the biggest killers worldwide. Chronic conditions include heart disease, stroke, diabetes, cancer, chronic respiratory disease and are often comorbid with mental illness. Over 60 years ago, the British Medical Journal reported an association between mental illness and poor physical health (Philips, 1934). Comorbid mental illness and physical illness incrementally worsens health compared with mental illness alone or any of the chronic non-communicable diseases such as cardiovascular diseases, cancers, chronic respiratory diseases and diabetes alone. This paper aims to open the dialogue related to optimising, through nursing intervention, a patient's self-righting and self-management factors in the context of comorbid chronic conditions such as heart disease, stroke, diabetes, cancer, chronic respiratory disease, with mental illness. Self-management and self-righting capabilities are now being considered integral to reducing the negative impact of chronic conditions such as mental illness. Personal characteristics associated with resilience comprise optimism, an active or adaptable coping style and the ability to elicit social support. Existing resilience factors can be assessed for by nurses and optimised through interventions when patients with chronic conditions are in care. Representing over 70% of the global health workforce, nurses are well positioned to enact such practice enhancements to facilitate better outcomes for patients.

OSA (obstructive sleep apnoea), the most common respiratory disorder of sleep, is caused by the loss of upper airway dilating muscle activity during sleep superimposed on a narrow upper airway. This results in recurrent nocturnal asphyxia. Termination of these events usually requires arousal from sleep and results in sleep fragmentation and hypoxaemia, which leads to poor quality sleep, excessive daytime sleepiness, reduced quality of life and numerous other serious health consequences. Furthermore, patients with untreated sleep apnoea are at an increased risk of hypertension, stroke, heart failure and atrial fibrillation. Although there are many predisposing risk factors for OSA, including male gender, endocrine disorders, use of muscle relaxants, smoking, fluid retention and increased age, the strongest risk factor is obesity. The aim of the present review is to focus on three cutting-edge topics with respect to OSA. The section on animal models covers various strategies used to simulate the physiology or the effects of OSA in animals, and how these have helped to understand some of the underlying mechanisms of OSA. The section on diabetes discusses current evidence in both humans and animal models demonstrating that intermittent hypoxia and sleep fragmentation has a negative impact on glucose tolerance. Finally, the section on cardiovascular biomarkers reviews the evidence supporting the use of these biomarkers to both measure some of the negative consequences of OSA, as well as the potential benefits of OSA therapies.

Ambient air pollution (AAP) and particulate matters (PM) have been closely associated with adverse health effects such as respiratory disease and cardiovascular diseases. Previous studies have examined the adverse health effects associated with short- and long-term exposure to AAP and outdoor PM on respiratory disease. However, the effect of PM size (PM2.5 and PM10) on cardiovascular disease has not been well studied. Thus, it remains unclear how the size of the inhalable particles (coarse, fine, or ultrafine) affects mortality and morbidity. Airborne PM concentrations are commonly used for ambient air quality management worldwide, owing to the known effects on cardiorespiratory health. In this article, we assess the relationship between cardiovascular diseases and PM, with a particular focus on PM size. We discuss the association of PM2.5 and PM10, nitrogen dioxide (NO2), and elemental carbon with mortality and morbidity due to cardiovascular diseases, stroke, and altered blood pressure, based on epidemiological studies. In addition, we provide evidence that the adverse health effects of AAP and PM are more pronounced among the elderly, children, and people with preexisting cardiovascular and respiratory conditions. Finally, we critically summarize the literature pertaining to cardiovascular diseases, including atherosclerosis and stroke, and introduce potential studies to better understand the health significance of AAP and PM on cardiovascular disease.

Chronic obstructive pulmonary disease (COPD) is a multisystem disease. Established comorbidities include cardiovascular disease, osteoporosis, loss of muscle mass and function, depression, and impaired quality of life. The natural history is not well understood. The Assessment of Risk in Chronic Airways Disease Evaluation (ARCADE) is a longitudinal study of comorbidities in COPD. The primary aims are to delineate the progression and interrelationships of cardiovascular disease and associated comorbidities. Each year ARCADE aims to recruit 250 patients diagnosed with COPD and 50 comparators (free from respiratory disease). Assessments include spirometry, body composition, blood pressure, aortic stiffness (pulse wave velocity (PWV)), noninvasive measures of cardiac output, systemic inflammatory mediators, blood and urine biochemistry, and physical and health outcomes. These will be repeated at 2 and 5 years. In the first year of recruitment, 350 patients and 100 comparators were recruited. The reproducibility of aortic PWV, cardiac output, stroke volume, and cardiac index was evaluated and accepted in 30 patients free from overt cardiovascular disease. The preliminary data from ARCADE have demonstrated acceptable reproducibility of hemodynamic outcome measures. Further longitudinal data collection will increase knowledge of the progression and interactions between cardiovascular risk factors and other comorbidities in COPD.

Poor oral health and hygiene are increasingly recognized as major risk factors for pneumonia among the elderly. To identify modifiable oral health-related risk factors, we prospectively investigated associations between a constellation of oral health behaviors and incident pneumonia in the community-living very elderly (i.e., 85 years of age or older). At baseline, 524 randomly selected seniors (228 men and 296 women; mean age, 87.8 years) were examined for oral health status and oral hygiene behaviors as well as medical assessment, including blood chemistry analysis, and followed up annually until first hospitalization for or death from pneumonia. During a 3-year follow-up period, 48 events associated with pneumonia (20 deaths and 28 acute hospitalizations) were identified. Among 453 denture wearers, 186 (40.8%) who wore their dentures during sleep were at higher risk for pneumonia than those who removed their dentures at night (log rank P = 0.021). In a multivariate Cox model, both perceived swallowing difficulties and overnight denture wearing were independently associated with an approximately 2.3-fold higher risk of the incidence of pneumonia (for perceived swallowing difficulties, hazard ratio [HR], 2.31; and 95% confidence interval [CI], 1.11-4.82; and for denture wearing during sleep, HR, 2.38; and 95% CI, 1.25-4.56), which was comparable with the HR attributable to cognitive impairment (HR, 2.15; 95% CI, 1.06-4.34), history of stroke (HR, 2.46; 95% CI, 1.13-5.35), and respiratory disease (HR, 2.25; 95% CI, 1.20-4.23). In addition, those who wore dentures during sleep were more likely to have tongue and denture plaque, gum inflammation, positive culture for Candida albicans, and higher levels of circulating interleukin-6 as compared with their counterparts. This study provided empirical evidence that denture wearing during sleep is associated not only with oral inflammatory and microbial burden but also with incident pneumonia, suggesting potential implications of oral hygiene programs for pneumonia prevention in the community.
