Based on data drawn from the 1993 and 2003 National Health Surveys (NHS), we sought to: estimate influenza vaccination coverages among Spanish cardiovascular disease (CVD) sufferers; study which variables were associated with the likelihood of being vaccinated; analyze the time-trend in coverage for the period 1993-2003. For study purposes, a CVD sufferer was defined as any adult who reported suffering from high blood pressure and/or heart disease. The proportion of vaccinated adult CVD sufferers in 1993 and 2003 totalled 39.96% and 51.73%, respectively. The following variables increased the likelihood of being vaccinated: higher age; male gender; presence of respiratory chronic diseases; non-smoker status. Coverages for CVD sufferers had improved significantly from 1993 to 2003 but still remain below desirable levels. The improvement over time is mainly due to the subgroup aged >64 years. Strategies must be implemented to improve the use of influenza vaccine among CVD sufferers in Spain in general, and among the younger age-groups in particular.

We conducted a prospective, observational study to characterize the clinical manifestations of respiratory infections caused by human metapneumovirus (hMPV) and other viruses in 194 premature infants and young children with chronic lung disease or congenital heart disease in Buenos Aires. Children had 567 episodes of respiratory illness and were monitored until they were 2 years old or until the completion of the study. hMPV elicited 12 infections (2%) year-round; 30% were of moderate or greater severity. Human parainfluenza virus type 3 caused 24 infections (4%), and 5 (25%) of 20 lung infections led to hospitalization. Respiratory syncytial virus (RSV) caused 33 episodes--17% of infections and 32% of hospitalizations during the respiratory season. None of the 10 children infected with influenza virus had severe disease. The present study of at-risk children suggests that hMPV and influenza virus are infrequent agents of severe disease and highlights the need for preventive interventions against RSV in developing countries.

This study aimed to determine the effectiveness of influenza vaccinations among the elderly in Bangkok in reducing influenza-like illness (ILI) and influenza-related complications. Using a non-randomized, controlled, prospective methodology, healthy, active people aged 60 years or more, living in the Bangkok Metropolitan Administration (BMA) area, were studied. The two study cohorts comprised 519 persons in the vaccinated group and 520 in the non-vaccinated group. The outcome under study was influenza-like illness (ILI), as reported by the study volunteers. The two groups were comparable for most socio-demographic characteristics, except for gender, level of education, marital status, and smoking habit. The age range was 60-88 years (mean: 68 years). Females outnumbered males in both groups, with ratio of female to male of 2.6:1 and 1.9:1 in the vaccinated and non-vaccinated groups, respectively. The top three co-morbidities among these groups were hypertension, diabetes mellitus, and heart disease, in that order. Only 1% of the volunteers reported lung disease as co-morbidity. During the 12-month study period, a total of 107 volunteers reported ILI in both groups, with 38 persons in the vaccinated group and 69 persons in the non-vaccinated group. There were 46 ILI episodes in the vaccinated group, and 86 in the non-vaccinated group, for a total of 132 episodes. The incidence rates rates of influenza in this population, therefore, were 8.9% for the vaccinated and 16.9% for the non-vaccinated groups; with a reduction in the rate of reported ILI and doctor visits of 8%. Vaccine effectiveness was rated at 47.6%, crude risk ratio at 1.9 (1.33-2.75), and adjusted risk ratio at 1.92 (95% CI: 1.25-2.95), after adjustment for gender, marital status, education, and smoking habit. No complications due to ILI were observed in this population during the study period. Hospitalizations during this period were due to non-ILI related causes, such as cancer and accident.

The recent discovery--from a meta-analysis of 18 randomized controlled trials--that supplemental cholecalciferol (vitamin D) significantly reduces all-cause mortality emphasizes the medical, ethical, and legal implications of promptly diagnosing and adequately treating vitamin D deficiency. Not only are such deficiencies common, and probably the rule, vitamin D deficiency is implicated in most of the diseases of civilization. Vitamin D's final metabolic product is a potent, pleiotropic, repair and maintenance, seco-steroid hormone that targets more than 200 human genes in a wide variety of tissues, meaning it has as many mechanisms of action as genes it targets. One of the most important genes vitamin D up-regulates is for cathelicidin, a naturally occurring broad-spectrum antibiotic. Natural vitamin D levels, those found in humans living in a sun-rich environment, are between 40-70 ng per ml, levels obtained by few modern humans. Assessing serum 25-hydroxy-vitamin D (25(OH)D) is the only way to make the diagnosis and to assure treatment is adequate and safe. Three treatment modalities exist for vitamin D deficiency: sunlight, artificial ultraviolet B (UVB) radiation, and vitamin D3 supplementation. Treatment of vitamin D deficiency in otherwise healthy patients with 2,000-7,000 IU vitamin D per day should be sufficient to maintain year-round 25(OH)D levels between 40-70 ng per mL. In those with serious illnesses associated with vitamin D deficiency, such as cancer, heart disease, multiple sclerosis, diabetes, autism, and a host of other illnesses, doses should be sufficient to maintain year-round 25(OH)D levels between 55 -70 ng per mL. Vitamin D-deficient patients with serious illness should not only be supplemented more aggressively than the well, they should have more frequent monitoring of serum 25(OH)D and serum calcium. Vitamin D should always be adjuvant treatment in patients with serious illnesses and never replace standard treatment. Theoretically, pharmacological doses of vitamin D (2,000 IU per kg per day for three days) may produce enough of the naturally occurring antibiotic cathelicidin to cure common viral respiratory infections, such as influenza and the common cold, but such a theory awaits further science.

Increasing evidences have shown that pathogens might promote atherosclerosis and trigger acute myocardial infarction (AMI). But the conclusions from various studies on the correlation between previous influenza virus (IV) infection and AMI were inconsistent. We conducted a case-control study to assess the association of previous IV infection and AMI. Questionnaire survey was conducted to collect information about demographic characteristics and heart disease risk factors. Fasting blood sample was obtained to measure IgG antibodies to influenza virus A(IV-A), influenza virus B(IV-B), cytomegalovirus (CMV), herpes simplex virus type-1 (HSV-1) and type-2 (HSV-2), adenovirus (ADV), rubella virus (RV) and Chlamydia pneumoniae (CP) and measure the level of some biochemistry markers. Compared to controls, cases were more likely to have positive IgG antibodies to IV-A and IV-B (IV-A: OR, 3.3; 95%CI, 1.5 to 7.4; IV-B: OR, 17.2; 95%CI, 7.7 to 38.0). After adjustment for potential confounding variables, the risk of AMI was still associated with the presence of IgG antibodies to IV-A (adjusted OR, 7.5; 95%CI, 1.3 to 43.0) and IV-B (adjusted OR, 27.3; 95%CI, 6.6 to 113.8). The study supported the hypothesis that previous IV infection took part in the development of atherosclerosis and trigger the occurrence of AMI.

The elderly and persons with specific chronic conditions are known to face elevated morbidity and mortality risks resulting from an influenza infection, and hence are routinely recommended for annual influenza vaccination. However, risk-specific mortality rates have not been established. We estimated age-specific influenza-attributable mortality rates stratified by the presence of chronic conditions and type of residence based on deaths of persons who were admitted to hospital with a respiratory complication captured in our national database. The majority of patients had chronic heart or respiratory conditions (80%) and were admitted from the community (80%). Influenza-attributable mortality rates clearly increase with age for all risk groups. Our influenza-specific estimates identified higher risk ratios for chronic lung or heart disease than have been suggested by other methods. These estimates identify groups most in need of improved vaccines and for whom the use of additional strategies, such as immunization of household contacts or caregivers should be considered.

Preventive health care decisions and recommendations become more complex as the population ages. The leading causes of death (i.e., heart disease, malignant neoplasms, cerebrovascular disease, and chronic lower respiratory disease) among older adults mirror the actual causes of death (i.e., tobacco use, poor diet, and physical inactivity) among persons of all ages. Many aspects of mortality in older adults are modifiable through behavior change. Patients 65 years and older should be counseled on smoking cessation, diets rich in healthy fats, aerobic exercise, and strength training. Other types of preventive care include aspirin therapy; lipid management; and administration of tetanus and diphtheria, pneumococcal, and influenza vaccines. Although cancer is the second leading cause of death in patients 65 years and older, a survival benefit from cancer screening is not seen unless the patient's life expectancy exceeds five years. Therefore, it is best to review life expectancy, functionality, and comorbidities with older patients when making cancer screening recommendations. Other recommended screenings include abdominal aortic aneurysm for men 65 to 75 years of age, breast cancer for women 40 years and older with a life expectancy greater than five years, and colorectal cancer for men and women 50 years and older with a life expectancy greater than five years.

We analyzed healthcare costs and medical conditions for 2,008 veterans with spinal cord injuries and disorders (SCI/Ds) near end of life. The average age at SCI/D onset and/ or occurrence was 42 years and at death was 66 years. The conditions that incurred the most costs included cancer (20.9%), influenza and/or pneumonia (15.1%), heart disease (13.5%), septicemia (5.9%), diabetes (5.3%), and stroke (5.1%). The average cost was $24,900 in the second year before end of life and reached $61,900 in the final year. Before end of life, costs accelerated during the final year from $3,100 in month 12 to $14,600 in the final month.

The authors present a newborn infant from the second pregnancy whose mother experienced influenza A infection in the first trimester. The birth was at term without complications, but 11 hours later, cyanosis and tachypnoe developed. The final diagnosis was hypoplastic left heart syndrome with simultaneous Moebius Syndrome. In conclusion the authors indicate that echocardiography is of great importance in the diagnosis of this complex heart disease as it helps to analyze in detail the options in the diagnosis of rare Moebius Syndrome (Fig. 2, Ref. 8).

THE OBSERVATIONS PRESENTED IN THIS PAPER MAY BE SUMMARIZED AS FOLLOWS: A study has been made on an isolated group of children with heart disease. All of these individuals, with one exception, were rheumatic subjects. Many of them carried a strain of hemolytic streptococcus in the throat flora during the winter of 1934. The organism produced no detectible toxin and was not associated with respiratory disease. Four patients contracted chicken pox during the winter months. None developed rheumatic recrudescences. All of the individuals were in good health on March 1. A severe epidemic of influenza began on March 22. All but six children contracted the disease. The filterable virus responsible for this outbreak was recovered. This agent did not activate the rheumatic process. It was followed by an outbreak of streptococcus infection and appeared to facilitate its spread. The source of these infections was not traced. They were due to a single type of hemolytic streptococcus which was a strong toxin producer. Its cultural, biochemical and serological characteristics were different from those of the carrier strain. Of seventeen individuals proven bacteriologically to be infected with the epidemic strain, fourteen rheumatic subjects developed acute rheumatism, two rheumatic subjects and one patient with congenital heart disease escaped. These fourteen rheumatic attacks were accompanied by a rise in antistreptolysin titer coincident with the onset of symptoms. In four of these attacks it was possible to exclude influenza as a causative factor. The clinical observations, the bacteriological findings and the immunological evidence indicate that this severe outbreak of rheumatic fever was caused by Streptococcus hemolyticus, which appeared to be a single strain by type.
