During the year 1985, 462 cases of septicemia were collected by SES group; 417 observations could be exploited. 73 patients died (17.3%). The statistical analysis of epidemiological and clinical data argued to factors correlated with high mortality rate: a shock, an acute respiratory distress syndrome, a pulmonary portal of entry lead to a high mortality rate. The fatal outcome increased with the age of the patients. A documented immunodeficiency (granulopenia, cytotoxic chemotherapy...), a previous broncho-pulmonary, neurologic or cardiovascular disease were factors of risk. The pulmonary or cutaneous localisations occurring within a septicemic phase were significantly related to death. Among fatal cases of bacteremia, 25% were Staphylococci, 25% Enterobacteria, 20% Pneumococci, 7% Pseudomonas. Pseudomonas, then Pneumococcus, then Staphylococcus bacteremias looks to have a worse prognosis. The more serious cases were prescribed several antibiotics, significantly much more than the mild cases. These results are compared with the results of former series; the main prognosis factors of actual septicemia are elicited in here.

The number of plasma cells, IgG+, IgA1+, IgA2+ and IgM+ cells were determined in bone marrow (BM) biopsies of 12 patients with common variable immunodeficiency syndrome (CVID) and 12 controls without signs of immunodeficiency. Controls had a median of 11 plasma cells/mm2, 76 IgG+, 76 IgA+ and 18 IgM+ cells/mm2 BM, respectively. Compared with the control group, the CVD patients showed a significant reduction of each cell type (p < 0.001). They also demonstrated a close correlation between low numbers of IgG+ and IgA+ cells in the BM and low IgG and IgA serum levels. In general, there was also a good correlation of the IgM+ cells and the respective IgM levels in the serum, except 2 CVID patients with normal IgM serum levels and subnormal numbers of IgM+ cells in the BM. Our results showed that there was an almost complete coincidence between the reduced numbers of Ig-producing cells in the BM and low serum levels of the respective Ig isotype. Thus, immunohistological analysis may be of additional help for the diagnosis of immunodeficiency.

Human immunodeficiency virus is known to enter the host at parenteral and mucosal sites and consequently an effective vaccine should stimulate immunity at both routes of entry. One approach toward stimulating HIV-specific mucosal and systemic immunity is the use of candidate live oral Salmonella typhi vector vaccine, strain CVD 908, which has been shown to stimulate mucosal and systemic immunity in volunteers. Using recombinant DNA techniques we constructed an expression cassette which comprises the lpp promoter (Plpp) and sequences encoding recombinant gp120 (rgp120). When the Plpp-rgp120 expression cassette is integrated into the chromosome of CVD 908 in the delta aroC allele, high levels of recombinant gp120 expression are observed. It is likely that effective immunity against HIV in humans will require immunization with multiple HIV antigens. Hence, a second expression cassette encoding two additional HIV antigens with vaccine potential, p24 (a HIV-1 gag gene product) and Nef (a putative regulator of HIV-1 gene expression) has been constructed. We plan to integrate the p24-Nef-encoding expression cassette into the aroD locus in the chromosome of CVD 908 delta aroC::rgp120 in a stable manner to produce a CVD 908-HIV vector vaccine that expresses multiple HIV antigens.

Young adults residing in four States were enrolled in the period 1985-88 in a multicenter study of cardiovascular disease risk factors. In 1989, 2,729 members of the group were given a self-administered questionnaire that included questions on changes in sexual behavior that subjects had made in response to the epidemic of acquired immunodeficiency syndrome (AIDS). The final sample of 1,601 young, heterosexual, urban respondents included 412 white men, 568 white women, 224 black men, and 397 black women, all ages 21 to 40 years. Overall, nearly 50 percent of the sample reported having made at least one change in their sexual behavior in response to the AIDS epidemic to decrease their risk of becoming infected by the human immunodeficiency virus. The mean number of changes was 0.8 for white men, 1.1 for white women, 1.6 for black men, and 1.5 for black women. Change was reported more frequently by black respondents than white, with no significant sex differences. The categories of respondents reporting behavior changes were more often young, with a history of recreational drug use, with more sex partners, or having had anal intercourse. The most commonly reported behavior changes were reducing the number of sex partners and being more careful in partner selection. Of the 54 percent of respondents who did not report any change in sexual behavior, about 70 percent reported unprotected sex with more than one partner in the previous year. Significant sexual behavior change in response to the AIDS epidemic remains a goal for health education efforts.

Cardiovascular disease (CVD) is the single most important cause of mortality in hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) patients. An increased lipoprotein (a) [Lp(a)] level in HD patients is associated with CVD. However, Lp(a) levels in CAPD patients are controversial, and their association with CVD has not been established. In the present study, prevalent CAPD and HD patients [excluding those who were human immunodeficiency virus (HIV)-positive] attending the Long Island College Hospital from June, 1990 to July, 1995 underwent analysis of lipid profile including Lp(a). Total and low-density lipoprotein cholesterol, triglycerides, apolipoprotein (apo) A, and apo B were all significantly increased in CAPD patients compared to HD patients. Serum Lp(a) levels were also significantly higher in CAPD patients than in HD patients (51 +/- 32 vs 34 +/- 23 mg/dL, p < 0.001). CAPD patients who had a history of myocardial infarction (MI) or coronary artery disease (CAD) at enrollment had significantly higher Lp(a) levels compared to those who did not have a history of MI or CAD. CAPD patients who died of CVD had higher Lp(a) levels than patients who died of non-CVD causes. In the Cox model with backward stepwise selection, a history of CVD was associated with a significantly elevated relative risk (RR) of mortality (RR = 1.84, p = 0.014). Expected survival by all causes of mortality and by cardiac mortality was significantly shorter in patients with a history of CVD than in those without a history of CVD. Thus, elevated Lp(a) is related to increased CVD and therefore may contribute to increased mortality in CAPD patients.

Priority health-risk behaviors, which contribute to the leading causes of mortality and morbidity among youth and adults, often are established during youth, extend into adulthood, and are interrelated. The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health-risk behaviors among youth and young adults--behaviors that contribute to unintentional and intentional injuries; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases (STDs) (including human immunodeficiency virus [HIV] infection); unhealthy dietary behaviors; and physical inactivity. The YRBSS includes a national school-based survey conducted by the Centers for Disease Control and Prevention as well as state, territorial, and local school-based surveys conducted by education and health agencies. This report summarizes results from the national survey, 33 state surveys, 3 territorial surveys, and 17 local surveys conducted among high school students from February through May 1997. In the United States, 73% of all deaths among youth and young adults 10-24 years of age result from only four causes: motor vehicle crashes, other unintentional injuries, homicide, and suicide. Results from the national 1997 YRBSS demonstrate that many high school students engage in behaviors that increase their likelihood of death from these four causes--19.3% had rarely or never worn a seat belt; during the 30 days preceding the survey, 36.6% had ridden with a driver who had been drinking alcohol; 18.3% had carried a weapon during the 30 days preceding the survey; 50.8% had drunk alcohol during the 30 days preceding the survey; 26.2% had used marijuana during the 30 days preceding the survey; and 7.7% had attempted suicide during the 12 months preceding the survey. Substantial morbidity among school-age youth, young adults, and their children also result from unintended pregnancies and STDs, including HIV infection. YRBSS results indicate that in 1997, 48.4% of high school students had ever had sexual intercourse; 43.2% of sexually active students had not used a condom at last sexual intercourse; and 2.1% had ever injected an illegal drug. Of all deaths and substantial morbidity among adults greater than or equal to 25 years of age, 67% result from two causes--cardiovascular disease and cancer. Most of the risk behaviors associated with these causes of death are initiated during adolescence. In 1997, 36.4% of high school students had smoked cigarettes during the 30 days preceding the survey; 70.7% had not eaten five or more servings of fruits and vegetables during the day preceding the survey; and 72.6% had not attended physical education class daily. These YRBSS data are already being used by health and education officials to improve national, state, and local policies and programs to reduce risks associated with the leading causes of morbidity and mortality. YRBSS data also are being used to measure progress toward achieving 21 national health objectives and one of the eight National Education Goals.

Alternative high schools serve approximately 280,000 students nationwide who are at high risk for failing or dropping out of regular high school or who have been expelled from regular high school because of illegal activity or behavioral problems. Such settings provide important opportunities for delivering health promotion education and services to these youth and young adults. However, before this survey, the prevalence of health-risk behaviors among students attending alternative high schools nationwide was unknown. The Youth Risk Behavior Surveillance System (YRBSS) monitors the following six categories of priority health-risk behaviors among youth and young adults: behaviors that contribute to unintentional and intentional injuries; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases (STDs) (including human immunodeficiency virus [HIV] infection); unhealthy dietary behaviors; and physical inactivity. The national Alternative High School Youth Risk Behavior Survey (ALT-YRBS) is one component of the YRBSS; it was conducted in 1998 to measure priority health-risk behaviors among students at alternative high schools. The 1998 ALT-YRBS used a three-stage cluster sample design to produce a nationally representative sample of students in grades 9-12 in the United States who attend alternative high schools. The school response rate was 81.0%, and the student response rate was 81.9%, resulting in an overall response rate of 66.3%. This report summarizes results from the 1998 ALT-YRBS. The reporting period is February-May 1998. In the United States, 73.6% of all deaths among youth and young adults aged 10-24 years results from only four causes--motor vehicle crashes, other unintentional injuries, homicide, and suicide. Results from the 1998 ALT-YRBS demonstrate that many students at alternative high schools engage in behaviors that increase their likelihood of death from these four causes. During the 30 days preceding the survey, 51.9% had ridden with a driver who had been drinking alcohol, 25.1% had driven a vehicle after drinking alcohol, 32.9% had carried a weapon, 64.5% had drunk alcohol, and 53.0% had used marijuana. During the 12 months preceding the survey, 15.7% had attempted suicide, and 29.0% had rarely or never worn a seat belt. Substantial morbidity among school-aged youth and young adults also results from unintended pregnancies and STDs, including HIV infection. ALT-YRBS results indicate that in 1998, a total of 87.8% of students at alternative high schools had had sexual intercourse, 54.1% of sexually active students had not used a condom at last sexual intercourse, and 5.7% had ever injected an illegal drug. Among adults aged > or = 25 years, 66.5% of all deaths result from two causes--cardiovascular disease and cancer. Most risk behaviors associated with these causes of death are initiated during adolescence. In 1998, a total of 64.1% of students at alternative high schools had smoked cigarettes during the 30 days preceding the survey, 38.3% had smoked a cigar during the 30 days preceding the survey, 71.2% had not eaten > or = 5 servings of fruits and vegetables during the day preceding the survey, and 81.0% had not attended physical education (PE) class daily. Comparing ALT-YRBS results with 1997 national YRBS results demonstrates that the prevalence of most risk behaviors is higher among students attending alternative high schools compared with students at regular high schools. Some risk behaviors are more common among certain sex and racial/ethnic subgroups of students. ALT-YRBS data can be used nationwide by health and education officials to improve policies and programs designed to reduce risk behaviors associated with the leading causes of morbidity and mortality among students attending alternative high schools.

The nutritional condition of children with human immunodeficiency virus (HIV) infection continues to be a problem both in developed and developing countries. HIV-infected children grow below normal standards in both height and weight when compared with HIV-exposed non-infected children. These patterns persist over time. It is possible that acute infectious episodes and increased HIV viral burden contribute to decrements in all growth variables. Potential aetiologies for abnormal growth include inadequate dietary intake, gastrointestinal malabsorption, increased energy utilization and psycho-social problems. It is likely that all these factors contribute to the growth problems of these children to some extent. With the development of protease inhibitor anti-retroviral therapy and highly-active anti-retroviral treatment regimens, children with HIV infection in developed countries are living longer with a chronic illness. New nutritional problems have arisen with the development of the fat redistribution syndrome or lipodystrophy. Emerging problems are now being recognized, with the development of insulin resistance and truncal obesity which may potentially lead to premature cardiovascular disease.

In a patient with severe ischemic heart disease and advanced human immunodeficiency virus (HIV) infection, vigorous perioperative treatment with anti-retroviral agents was given and coronary artery bypass surgery using cardiopulmonary bypass was successfully performed. This strategy could become the standard for patients with cardiovascular disease and advanced HIV infection. The following aspects of this case require further investigation: (1) lack of a reactive increase in the neutrophil count, (2) transient extreme reduction of lymphocytes, and (3) a relative decrease in the CD8+ cell ratio.

Priority health-risk behaviors, which contribute to the leading causes of mortality and morbidity among youth and adults, often are established during youth, extend into adulthood, are interrelated, and are preventable. The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health-risk behaviors among youth and young adults--behaviors that contribute to unintentional and intentional injuries; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases (STDs) (including human immunodeficiency virus [HIV] infection); unhealthy dietary behaviors; and physical inactivity. The YRBSS includes a national school-based survey conducted by CDC as well as state, territorial, and local school-based surveys conducted by education and health agencies. This report summarizes results from the national survey, 33 state surveys, and 16 local surveys conducted among high school students during February through May 1999. In the United States, approximately three fourths of all deaths among persons aged 10-24 years result from only four causes: motor-vehicle crashes, other unintentional injuries, homicide, and suicide. Results from the 1999 national Youth Risk Behavior Survey demonstrate that numerous high school students engage in behaviors that increase their likelihood of death from these four causes--16.4% had rarely or never worn a seat belt; during the 30 days preceding the survey, 33.1% had ridden with a driver who had been drinking alcohol; 17.3% had carried a weapon during the 30 days preceding the survey; 50.0% had drunk alcohol during the 30 days preceding the survey; 26.7% had used marijuana during the 30 days preceding the survey; and 7.8% had attempted suicide during the 12 months preceding the survey. Substantial morbidity and social problems among young persons also result from unintended pregnancies and STDs, including HIV infection. In 1999, nationwide, 49.9% of high school students had ever had sexual intercourse; 42.0% of sexually active students had not used a condom at last sexual intercourse; and 1.8% had ever injected an illegal drug. Two thirds of all deaths among persons aged > or = 25 years result from only two causes--cardiovascular disease and cancer. The majority of risk behaviors associated with these two causes of death are initiated during adolescence. In 1999, 34.8% of high school students had smoked cigarettes during the 30 days preceding the survey; 76.1% had not eaten > or = 5 servings/day of fruits and vegetables during the 7 days preceding the survey; 16.0% were at risk for becoming overweight; and 70.9% did not attend physical education class daily. These YRBSS data are already being used by health and education officials at national, state, and local levels to analyze and improve policies and programs to reduce priority health-risk behaviors among youth. The YRBSS data also are being used to measure progress toward achieving 16 national health objectives for 2010 and 3 of the 10 leading health indicators.
