qSOFA as a predictor of ICU outcomes in a resource-limited setting in KwaZulu-Natal Province, South Africa.

Background: Sepsis is a major cause of morbidity and mortality, especially in critical care patients. Developing tools to identify patients who are at risk of poor outcomes and prolonged length of stay in intensive care units (ICUs) is critical, particularly in resource-limited settings. Objectives: To determine whether the quick sequential organ failure assessment (qSOFA) score based on bedside assessment alone was a promising tool for risk prediction in low-resource settings. Methods: A retrospective cohort of adult patients admitted to the intensive care unit (ICU) at Edendale Hospital in Pietermaritzburg, South Africa (SA), was recruited into the study between 2014 and 2018. The association of qSOFA with in-ICU mortality was measured using multivariable logistic regression. Discrimination was assessed using the area under the receiver operating characteristic curve and the additive contribution to a baseline model using likelihood ratio testing. Results: The qSOFA scores of 0, 1 and 2 were not associated with increased odds of in-ICU mortality (adjusted odds ratio (aOR) 1.24, 95% confidence interval (CI) 0.86 - 1.79; p=0.26) in patients with infection, while the qSOFA of 3 was associated with in-ICU mortality in infected patients (aOR 2.82; 95% CI 1.91 - 4.16; p<0.001). On the other hand, the qSOFA scores of 2 (aOR 3.25; 95% CI 1.91 - 5.53; p<0.001) and 3 (aOR 6.26, 95% CI 0.38 - 11.62, p<0.001) were associated with increased odds of in-ICU mortality in patients without infection. Discrimination for mortality was fair to poor and adding qSOFA to a baseline model yielded a statistical improvement in both cases (p<0.001). Conclusion: qSOFA was associated with, but weakly discriminant, for in-ICU mortality for patients with and without infection in a resource-limited, public hospital in SA. These findings add to the growing body of evidence that support the use of qSOFA to deliver low-cost, high-value critical care in resource-limited settings. Contributions of the study: This study expanded the data supporting the use of qSOFA in resource-limited settings beyond the emergency department or ward to include patients admitted to the ICU. Additionally, this study demonstrated stronger predictive abilities in a population of patients admitted with trauma without suspected or confirmed infection, thus providing an additional use of qSOFA as a risk-prediction tool for a broader population.

The relationship of unsafe sexual behavior and the characteristics of sexual partners of HIV infected and HIV uninfected adolescent females.

PURPOSE: To compare characteristics of sexual relationships in HIV infected and HIV uninfected female adolescents and their association with condom use. METHODS: HIV infected and uninfected subjects, aged 13-19 years, were enrolled in a prospective HIV study from 15 sites in 13 U.S. cities. Baseline data on demographic information, substance use, sexual behavior, partner information, and condom use were collected through direct and computer-assisted interviews from currently sexually active females. Univariate, multiple logistic regression, and repeated measures analyses were employed. RESULTS: Data from 153 HIV infected and 90 HIV uninfected female subjects showed, on average, that current partners were 4-6 years older. In multivariate analysis, HIV infected subjects were older (OR = 1.37; 95% CI: 1.04-1.81), had more lifetime partners (OR = 2.23; 95% CI: 1.03-4.82), initiated consensual vaginal sex earlier (OR = .74; 95% CI:.58-.95), perceived partner to also be HIV infected (OR = 7.46; 95% CI: 3.2-17.4), and had less unprotected sex (OR = .27; 95% CI:.16-.45). Length of relationship was associated with more unprotected sex for both HIV infected and uninfected subjects (OR = 2.59, 95% CI: 1.27-5.27, OR = 4.13; 95% CI: 1.31-13.05, respectively). Mean partner age difference was greater among HIV infected than for HIV uninfected (OR = 1.06; 95%CI: 1.01-1.12); this greater age difference for HIV infected females was associated with less protection (OR = 1.09; 95% CI: 1.03-1.15). HIV disclosure influenced condom use: without disclosure, less condom use was reported (OR = 6.8; 95% CI: 2.29-20.24) controlling for perception that partner was also HIV infected (OR = 1.1; 95% CI: 1.02-1.21). CONCLUSIONS: Because age differential influenced reported condom use, more research, particularly qualitative, is needed into the dynamics of these relationships. Prevention efforts must address partners, particularly older ones.

Health-related service utilization and HIV risk behaviors among HIV infected injection drug users and crack smokers.

This study was designed to assess utilization of health-related services and HIV risk related behaviors by HIV infected drug users one year prior to and two years following the availability of Ryan White Title I funding. Using a cross-sectional design, a total of 777 drug injectors and crack smokers from five US cities were surveyed, over three waves of data collection, about their use of drug treatment, medical services, housing, mental health, and case management and about their sex and drug-related risk behaviors. For all service categories and in each wave, including the year prior to Title I funding, HIV risk behaviors were lower among those who used health-related services, with the exception of housing. Use of services did not increase significantly following the disbursement of Title I funds except for housing and case management. These findings suggest that it may be necessary to increase the attractiveness of health-related services, not just funding for services, for HIV infected substance abusers.

Reiter's syndrome among Asian shipboard immigrants: the case of The Golden Venture.

OBJECTIVE: To assess the incidence of Reiter's syndrome aboard The Golden Venture, a ship carrying illegal immigrants from China to the United States. METHODS: After identification of an index case, we conducted telephone interviews with medical staff at immigrant detention centers in Pennsylvania, New York, and Virginia. When a potential case was identified at one facility, we performed a site inspection, reviewing the medical records of all detainees and performing histories and physicals on all those with joint and/or ocular complaints. RESULTS: We identified two patients, both HLA B27 positive, with Reiter's syndrome. The observed incidence (0.87%) approximated the predicted incidence but may have underestimated the actual incidence. We review the history of shipboard Reiter's syndrome, and discuss the pathogenic roles of HLA B27 and particular infectious agents. CONCLUSION: Continued transportation of illegal immigrants from China and other parts of the world is likely to result in occasional clusters of Reiter's syndrome. Physicians treating immigrant populations should remain aware of the possibility of reactive arthritis.

HRSA's strategies to combat family violence.

This paper discusses the efforts of the Health Resources and Services Administration (HRSA) to work with a broad constituency to combat and ultimately prevent family violence. In partnership with states and communities, HRSA implements programs to strengthen health care infrastructure, support direct community-based service delivery, and educate health care providers. Soliciting and incorporating community input are critical steps in designing innovative training approaches to deal with pressing health concerns, such as the efforts of family violence in a community. This type of collaboration is evident in HRSA's programs such as the Area Health Education Centers, the Geriatric Education Centers, and the AIDS Education and Training Centers. Health care delivery systems and special health interventions must respond to the far-reaching effects of family violence. HRSA is devising a comprehensive strategy to guide program development in violence intervention. This strategy would build on successful models of education, prevention, and service delivery, as well as identification of critical areas for collaboration between community activists, researchers, epidemiologists, health care providers, policymakers, academicians, survivors, philanthropists, representatives from state and local government, and the faith community.

A hospital/school science fair mentoring program for middle school students.

The Massachusetts General Hospital (MGH) and the James P. Timilty Middle School established a partnership to enhance science education, promote faculty development, and improve the health status and academic performance of all Timilty students. This article describes one of the Partnership's Science Connection programs, the Science Fair Mentoring Program, designed to enhance middle school science education, inform urban early adolescents about professions in the health field, inspire them to pursue postsecondary study in the health sciences, and prepare them for rigorous academic work in high school. In this program, hospital-based clinical and research staff mentor young adolescent students. The authors describe the planning, implementation, and evaluation of the Science Fair Mentoring Program as an innovative learning experience.

Increased oxidative stress and decreased antioxidant defenses in mucosa of inflammatory bowel disease.

Inflammatory bowel disease (IBD) is characterized by chronic intestinal inflammation whose cellular components are capable of oxidative respiratory bursts that may result in tissue injury. Mucosal biopsies were analyzed for protein carbonyl content (POPs), DNA oxidation products [8-hydroxy-2'-deoxyguanosine (8-OHdG)], reactive oxygen intermediates (ROIs), trace metals (copper, zinc, and iron) and superoxide dismutase (Cu-Zn SOD). In Crohn's disease biopsies, there was an increase in ROIs, POPs, 8-OHdG, and iron, while decreased copper and Cu-Zn SOD activity were found in inflamed tissues compared to controls. For ulcerative colitis, there was an increase in ROIs, POPs, and iron in inflamed tissue compared to controls, while decreased zinc and copper were observed. An imbalance in the formation of reactive oxygen species and antioxidant micronutrients may be important in the pathogenesis and/or perpetuation of the tissue injury in IBD and may provide a rationale for therapeutic modulation with antioxidants.

The Harvard Nursing Research Institute's conference summary.

The Harvard Nursing Research Institute organized a national invitational conference on executive nursing leadership in major teaching hospitals and academic health centers. The conference brought together many of the nation's eminent nurse executives and other prominent individuals in healthcare to analyze the unique and complex challenges facing these organizations, expose participants to other perspectives, and articulate specific aims and strategies that might be taken to increase their effectiveness in leading the nursing profession's efforts to shape the ongoing transformation of the healthcare system.

Inflammatory bowel disease mucosal biopsies have specialized lymphokine mRNA profiles.

: Crohn's disease (CD) and ulcerative colitis (UC) are idiopathic inflammatory bowel diseases (IBD) that are characterized by chronic intestinal inflammation and are associated with abnormalities of peripheral and mucosal immune function. The aim of our study was to determine whether CD or UC is characterized by discrete profiles of intestinal lymphokine production. Total cellular RNA was isolated from biopsies of healthy controls and from patients with IBD. Messenger RNA transcript levels in biopsies were determined for interleukin-2 (IL-2), IL-4, IL-5, and interferon-γ (IFN-γ), using a quantitative reverse transcriptase polymerase chain reaction method. Compared with inflamed UC mucosa and controls, CD mucosal lesions contained higher IL-2 and IFN-γ mRNA (p < 0.05), which is consistent with a T-helper cell 1 (Th1)-like pattern. In UC, IL-5 mRNA content was higher in involved areas compared with controls (p < 0.05) and inflamed CD lesions (p < 0.05), suggestive of a Th2 pattern. We conclude that the intestinal mucosa of CD and UC have inflammatory responses characterized by discrete T-helper profiles of lymphokines. This strongly suggests that the immunopathogenesis of these two forms of IBD are different.

Women living with drug abuse and HIV disease: drug abuse treatment access and secondary prevention issues.

In collaboration with the National Institute on Drug Abuse, the Health Resources and Services Administration is conducting a multisite, longitudinal study on issues of service needs, service utilization, and access to care for drug abusers with HIV. This article discusses access to drug abuse treatment and HIV secondary prevention for 116 women interviewed during the study's first year in five U.S. cities. Using interview data from 115 service providers in those same cities, it also discusses drug abuse treatment availability and barriers to service expansion for drug users with HIV. Study findings indicate that there are highly significant gaps between the drug abuse treatment services these women feel they need and those they have been able to receive; these were particularly pronounced for drug detoxification and residential and outpatient drug-free treatment. Women who used crack cocaine or injection drugs had particularly high levels of need for residential and outpatient drug abuse treatment, while women who use crack were found to have significantly less experience with the drug abuse treatment system than IDUs. HIV secondary prevention was also found to be a critical need for these women, many of whom were engaging in behaviors that place them at risk for reinfection, infection with other diseases, and transmission to others. Providers indicated that lack of funding was the major barrier to expanding services for this population; other barriers, such as lack of ancillary services and transportation, were also noted. Two positive findings were that many drug abuse treatment agencies in these cities provide a wide range of ancillary services and that many different kinds of agencies offer drug abuse treatment services.

Women living with substance abuse and HIV disease: medical care access issues.

This paper presents first-year findings from a multi-site, longitudinal study being coordinated by the Health Resources and Services Administration (HRSA) in collaboration with the National Institute on Drug Abuse (NIDA) on access to care for drug abusers with HIV. The sample of 116 women and 187 men in five sites (Denver, Detroit, New Haven, New Orleans, and St. Louis) were interviewed regarding HIV testing history, HIV disease course, and use of health and social services. For both men and women, there were significant gaps between the medical services they reported needing and those they received. Significantly more women needed and received mental health services. Cost and waiting times emerged as the most important barriers to care. The study also found that significantly fewer women than men subjects received pre- and post-test counseling and were advised to get medical services after their first positive HIV test. Overall, first-year study results suggest that multiple barriers in access to service exist for drug-using women, the largest group of women affected by HIV in the United States.

Appropriate response to pneumococcal vaccine in celiac sprue.

Hyposplenism as a complication of celiac sprue confers an increased risk of pneumococcal sepsis, but such patients do not routinely receive pneumococcal vaccine despite reports of overwhelming pneumococcal sepsis. Because antibody response in these patients has not been previously assessed, we measured pre- and postvaccination levels in 10 patients with documented sprue. All demonstrated appropriate acute antibody responses to a polyvalent pneumococcal vaccine. Vaccination of all patients with celiac sprue seems appropriate.

Intestinal microsporidiosis. Report of five cases.

Five cases of intestinal microsporidiosis are reported, including one case of a heterosexual female acquired immunodeficiency syndrome (AIDS) patient, three homosexual males, and one bisexual male AIDS patients with detailed description of their clinical course. These five cases underscore the severity of immunodeficiency in patients with microsporidiosis. All patients had multiple opportunistic infections and a CD4 cell count below 100/microliters long before diarrhea developed. This is the first kinetic study of helper T-lymphocytes in cases of microsporidiosis. Diagnosis was made by duodenal biopsies stained with Brown and Brenn or Gram-Weigert technique (confirmed by electron microscopy) and by stool smears stained with a modified trichrome technique. However, the best preparation was plastic sections stained with toluidine blue, which demonstrated both the spores and plasmodia clearly. In our evaluation, Giemsa stain was also acceptable for identification of microsporidian spores in both intestinal biopsies and stool smears, but there was a failure to identify the organism on hematoxylin and eosin, acid-fast, periodic acid-Schiff, and Gomeri's methenamine silver stained preparations. Therapeutic attempts using albendazole, metronidazole, octreotide, and zidovudine (AZT) failed to eradicate microsporidia in these patients.

Creating an agenda for research and evaluation: HIV service delivery, the Ryan White CARE Act, and beyond.

HRSA, AHCPR and NCAP convened a working meeting in November 1992, to discuss creation of a national agenda for research and evaluation on HIV service delivery systems that are cost-effective, responsive to the needs of the diverse populations affected by the epidemic, and reflective of the lessons learned so far. In this article, the interests and goals of the conveners are described, the meeting's process and outcomes are discussed, and the nine key study areas that were identified and chosen by the meeting participants are presented. It is hoped that this article will stimulate further interest among private and public funders and among the research community in fostering the implementation of HIV service delivery-related research and evaluation studies. If this is accomplished, decision-makers will be better enabled to make informed and responsive policy decisions.

A century of progress: nursing quality improvement at the Mount Sinai Medical Center.

Since The Mount Sinai Hospital in New York City began delivering care in the mid 1800s, the medical services and, shortly thereafter, the nursing service have consistently given priority to improving patient care. Through the decades of the late 19th and 20th centuries, the Department of Nursing has remained current with the evolving concept of quality improvement. A historical overview of key elements in the evolution of quality improvement in nursing is presented.
