First Trimester Prenatal Care Initiation Among Hispanic Women Along the U.S.-Mexico Border

Background First trimester prenatal care (FTPNC) is associated with improved birth outcomes. U.S.-Mexico border Hispanic women have lower FTPNC than non-border or non-Hispanic women. This study aimed to identify (1) what demographic, knowledge and care-seeking factors influence FTPNC among Hispanic women in border counties served by five Healthy Start sites, and (2) what FTPNC barriers may be unique to this target population. Healthy Starts work to eliminate disparities in perinatal health in areas with high poverty and poor birth outcomes. Methods 403 Hispanic women of reproductive age in border communities of California, Arizona, New Mexico and Texas were surveyed on knowledge and behaviors related to prenatal care (PNC) and basic demographic information. Chi square analyses and logistic regressions were used to identify important relationships. Results Chi square analyses revealed that primiparous women were significantly less likely to start FTPNC than multiparous women (χ² = 6.8372, p = 0.0089). Women with accurate knowledge about FTPNC were more likely to obtain FTPNC (χ² = 29.280, p < .001) and more likely to have seen a doctor within the past year (χ² = 5.550, p = .018). Logistic regression confirmed that multiparity was associated with FTPNC and also that living in Texas was negatively associated with FTPNC (R² = 0.066, F(9,340) = 2.662, p = .005). Among 27 women with non-FTPNC, barriers included late pregnancy recognition (n = 19) and no medical insurance (n = 5). Conclusions This study supports research that first time pregnancies have lower FTPNC, and demonstrated a strong association between delayed PNC and late pregnancy recognition. Strengthened investments in preconception planning could improve FTPNC in this population.

The effects of priming on a public health campaign targeting cardiovascular risks

Public health interventions are cost-effective methods to reduce heart disease. The present study investigated the impact of a low-cost priming technique on a public health campaign targeting cardiovascular risk. Participants were 415 individuals (66% female) ages 18 and older recruited through clinics and churches. The study consisted of three phases. In Phase I, participants completed a brief survey to assess knowledge of the cardiovascular health indicators. The survey served as the prime (intervention) for the study. At Phase II, participants were provided with access to a public health campaign consisting of an education brochure on cardiovascular health. Following the educational campaign, all participants completed a post-campaign survey in Phase III of the study. Participants who completed the surveys in both Phase I and III were placed in the intervention condition (26%) and those who only completed the Phase III survey were placed in the control condition (74%). Participants who were primed reported greater awareness of the public health campaign. Additionally, more intervention participants reported they had knowledge of their own and the normal ranges for cholesterol, glucose, and body mass index. For participants who were aware of the health promotion campaign, more participants in the primed group indicated they had knowledge of their own cholesterol and glucose levels and had made positive lifestyle changes as a result of the campaign. Results suggest the presence of a priming effect. Public health campaigns may benefit from the inclusion of a low-cost prime prior to intervention.

Lessons from the fields: a migrant HIV prevention project

Migrant and seasonal workers are vulnerable to human immunodeficiency virus (HIV) due to poverty, inadequate knowledge of preventive strategies, and lack of access to health care. This study addresses the disparate impact of HIV among Hispanic and African American migrant workers in Immokalee, Florida, who use alcohol and other drugs. Through pilot testing to adapt the experimental and comparison interventions to these two distinct populations, research staff have learned the importance of (1) establishing and maintaining trust between outreach staff and the migrant community; (2) being aware of cultural nuances and practices that might create challenges to the research process, and the interaction of these factors with poverty; and (3) having flexibility in recruitment and intervention. As one of the first intervention studies in this population to use an experimental design and to focus on the social and contextual factors that contribute to risky behaviors, these lessons may provide guidance for future researchers.

The relationship of character strengths to sexual behaviors and related risks among African American adolescents

BACKGROUND

Relatively few studies have examined positive character traits that are associated with lower HIV/STD risks.

PURPOSE

In the present study, the relationships of character strengths with sexual behaviors and attitudes were assessed among 383 African-American adolescents.

METHOD

Character strengths were measured using the Values in Action Inventory of Strengths. Because the strengths were highly inter-correlated, stepwise discriminant function analyses were utilized to assess their independent associations with sexual behaviors and attitudes.

RESULTS

Greater Love of Learning was related to self-reported abstinence from sexual intercourse for boys and self-reported abstinence from drug use for boys and girls. Greater Love of Learning and Curiosity were related to the belief in no premarital sex for boys, whereas only Curiosity was significant for girls. Prudence was related to reported abstinence from sexual intimacy (e.g., touching or kissing). Judgment was related to sexual initiation efficacy for girls and boys, whereas Leadership was only significant for girls.

CONCLUSIONS

The findings suggest that character strengths may be associated with lower levels of sexual behaviors and sex-related beliefs among a sample of African-American adolescents.

An audit of gynaecological procedures in Jehovah's Witnesses in an inner city hospital

A retrospective study of Jehovah Witness women between January 1994 and December 2003 was performed. Gynaecologists are concerned about operating on Jehovah's Witnesses because of the potential for haemorrhage during surgery. Jehovah's Witnesses do not accept donor blood but some will permit their own blood to be stored pre-operatively and administered during surgery if deemed necessary. Approximately 150,000 Jehovah's Witnesses live in the UK but little on gynaecological procedures in Jehovah's Witnesses has been published. There were 64 procedures (14 major, 18 intermediate and 32 minor) in 53 women with a median age of 42 years. There were no perioperative deaths, but postoperative anaemia was common. Our study showed that major, intermediate and minor gynaecological procedures can be performed without significant morbidity on Jehovah's Witnesses but a protocol should be available to outline management of those who refuse blood.

Cultural adaptation in translational research: field experiences

The increase in the incidence of HIV/AIDS among minorities in the United States and in certain developing nations has prompted new intervention priorities, stressing the adaptation of efficacious interventions for diverse and marginalized groups. The experiences of Florida International University's AIDS Prevention Program in translating HIV primary and secondary prevention interventions among these multicultural populations provide insight into the process of cultural adaptations and address the new scientific emphasis on ecological validity. An iterative process involving forward and backward translation, a cultural linguistic committee, focus group discussions, documentation of project procedures, and consultations with other researchers in the field was used to modify interventions. This article presents strategies used to ensure fidelity in implementing the efficacious core components of evidence-based interventions for reducing HIV transmission and drug use behaviors and the challenges posed by making cultural adaptation for participants with low literacy. This experience demonstrates the importance of integrating culturally relevant material in the translation process with intense focus on language and nuance. The process must ensure that the level of intervention is appropriate for the educational level of participants. Furthermore, the rights of participants must be protected during consenting procedures by instituting policies that recognize the socioeconomic, educational, and systemic pressures to participate in research.

A Comparison of African American and Cuban American Adolescent Juvenile Offenders: Risky Sexual and Drug Use Behaviors

Racial and ethnic disparities exist in HIV seroconversion rates, with African American and Hispanic youth in the 13-19-year-old age group representing 61% and 21% of new AIDS cases, respectively. The aim of this study was to examine sexual and drug use behaviors among a sample of 138 African American and Cuban American juvenile offenders. Cuban American adolescents showed higher levels of unprotected sex, higher levels of sex while using drugs, and higher levels of drug/alcohol use in the three and six months prior to confinement. These differences may be explained by multiple factors, including differences in acculturation levels among the Cuban American adolescents, differences in health messages targeted at the two groups, and family mores and norms.

Major depression among adolescent smokers undergoing treatment for nicotine dependence

This is the first study to examine the prevalence and effects of major depression (MDD) in a sample of adolescent smokers (N = 211) undergoing treatment for nicotine dependence. We assessed MDD at baseline and end of treatment with the mood disorders portion of the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). Eleven percent of participants reported a history of MDD (6% of males and 21% of females). Study variables did not distinguish those with and without a history of MDD. End of treatment abstinence rates and relapse rates were similar in both groups. Two participants (1%), both female, experienced onset of MDD during the treatment. The findings provide further evidence that MDD is a comparatively common disorder among children and adolescents and that clinicians should monitor and be prepared to respond to depression that may emerge during the treatment of nicotine-dependent adolescents.

Randomized clinical trial of the efficacy of bupropion combined with nicotine patch in the treatment of adolescent smokers

Adolescent smokers (N = 211) were randomized to 1 of 2 groups: (a) nicotine patch plus bupropion SR (sustained release; 150 mg per day) or (b) nicotine patch plus placebo. Group skills training sessions were conducted each week by research staff. Abstinence rates at Weeks 10 and 26 were as follows: (a) patch plus bupropion, 23% and 8%, (b) patch plus placebo, 28% and 7%. Despite the lack of a treatment effect, a large majority of adolescents in both treatment groups reduced their consumption to a few cigarettes per day or less and maintained this reduction over time. Similarly, an examination of survival curves revealed that by the end of treatment many had managed to avoid a return to daily smoking. These findings are encouraging and suggest new avenues for research. For example, treatments of the kind examined in this report, augmented by extended maintenance therapies, may yield higher long-term success rates.

A survey of chronic renal failure in Jamaica

The prevalence of chronic renal failure (CRF)/end stage renal disease and the accessibility of long term renal replacement therapy in Jamaica were evaluated. The study was conducted at six Jamaican healthcare facilities between July 1998 and December 1999 and included 605 patients with CRF. Men with CRF (57% of patients, mean age of 56.7 years) were significantly older than women (mean age 53.2 years). Hypertension was the most commonly associated medical condition (60.8% of patients) followed by diabetes mellitus (31.4% of patients). The estimated crude point prevalence of CRF in persons 20 years and over at the end of 1999 was 327 per million population. More than one-third of patients with CRF (39%) were receiving renal replacement therapy, the most common modality being haemodialysis, and only 1.8% of patients had received kidney transplantation. The prevalence of chronic renal failure was not increased in areas known to have high soil cadmium levels. Chronic renal failure is a significant public health problem in Jamaica and is placing an increasing financial burden on the healthcare sector.

The Protective Role of the Family and Social Support Network in a Sample of HIV-Positive African American Women: Results of a Pilot Study

This study examined the role of family functioning and social support in protecting HIV-positive African American women from the adverse psychological consequences associated with deterioration in their CD4 cell count. Participants were 38 African American HIV-positive women who had recently given birth. Results demonstrated that changes in CD4 cell counts were inversely predictive of psychological distress and were moderated by family functioning and social support satisfaction. Women with good family functioning were less affected by changes in their CD4 cell counts, and women with poor family functioning were more emotionally responsive to changes in CD4 cell count. Unexpectedly, women from families where conflicts tended to be clearly laid out and discussed were also more responsive to both changes in CD4 cell counts. Interventions are recommended that increase a client's social support satisfaction, foster an adaptive level of connectedness to family, and enhance the family's range of conflict resolution styles.

Renal multigated spectral Doppler imaging before and after captopril challenge

RATIONALE AND OBJECTIVES

A new method of measurement, simultaneous multigated spectral Doppler imaging (MSDI), was used to quantify the hemodynamic changes in kidneys after administration of captopril.

METHODS

Forty kidneys in 22 hypertensive patients were included in the study. All underwent MSDI and scintigraphy before and after administration of captopril.

RESULTS

With scintigraphy used as the gold standard for diagnosing renal artery stenosis (RAS), three kidneys were found to be positive for RAS. Multigated spectral Doppler imaging detected a decrease in the resistive index after administration of captopril in all patients with RAS and correctly excluded RAS in one patient who was diagnosed as having RAS on scintigraphy. The resistive index was increased after captopril administration in normally functioning kidneys and was unchanged in kidneys with impaired function.

CONCLUSIONS

With further supportive evidence, MSDI may prove to be a powerful tool for the acquisition of resistive index information and may increase the value of the resistive index as a physiological hemodynamic parameter in the evaluation of normal and abnormal conditions.

Femoral artery pseudoaneurysm: Doppler sonographic features predictive for spontaneous thrombosis

PURPOSE

The objective of this prospective study was to evaluate whether Doppler imaging characteristics can be used to predict spontaneous thrombosis of femoral artery pseudoaneurysms (PAs).

METHODS

Eleven post-cardiac catheterization PAs were monitored with color Doppler sonography. Total volume of the lesion, volume filled with free-flowing blood, length and width of the neck of the PA, and its anatomic position were evaluated.

RESULTS

All of the PAs in our series underwent spontaneous thrombosis. PAs with necks 0.9 cm or longer underwent spontaneous thrombosis in 9.8 days on average, while PAs with necks shorter than 0.9 cm required an average of 52 days to thrombose.

CONCLUSIONS

PAs with longer neck lengths are more likely to thrombose in a shorter period than are those with shorter necks. It may thus be worthwhile to await spontaneous resolution when the aneurysmal neck length is 0.9 cm or more.

Audit pinpoints i.v. drug administration pitfalls

This paper describes an approach to auditing the time spent by nurses giving intravenous drugs. The results of the audit, carried out at Wycombe General Hospital, are reported and discussed together with the measures taken to address practical and medico-legal issues. The authors conclude that much nursing time could be saved with closer adherence to guidelines for practice.

Smooth landings. A safe approach to air medicine

As the number of patients transported by air medical services increases, so do concerns over safety in the skies. The NTSB and air medical associations are making strides in imposing safety controls and exploring other options that will improve the industry's safety record.

Ultrasonographic determination of renal mass and renal volume

Volumes and surface areas of 45 kidneys were determined ultrasonographically in vivo before autopsy and in a water bath phantom after autopsy by means of both the ellipsoid and the stepped section methods. Comparison of results revealed that renal volume may be determined by the simplest method, the ellipsoid method, with sufficient accuracy for clinical use. Results also revealed that renal mass expressed in grams may be directly obtained from renal volume expressed in milliliters, but mass in grams was found to correlate better with renal surface area than with renal volume. A formula relating renal mass to both volume and surface area was developed from regression analysis of the data and was found to provide a more precise estimate of renal mass than does mass computed from either volume or surface area alone.
