Acculturation and the prevalence of depression in older Mexican Americans: baseline results of the Sacramento Area Latino Study on Aging

OBJECTIVE: To determine the association between acculturation, immigration, and prevalence of depression in older Mexican Americans. DESIGN: Cross-sectional analysis from a cohort study. SETTING: Urban and rural counties of the Central Valley of Northern California. PARTICIPANTS: One thousand seven hundred and eighty-nine Latinos recruited from a population-based sample (85% Mexican Americans) with a mean age of 70.6 (range 60-100; standard deviation (SD) = 7.13); 58.2% were women. MEASUREMENTS: Depressive symptoms were assessed with the Center for Epidemiologic Studies--Depression scale (CES-D). Acculturation was measured with the Acculturation Rating Scale for Mexican Americans--II. Psychosocial, behavioral, and medical histories were also obtained. RESULTS: The prevalence of depression (CES-D > or = 16) was 25.4%. Women were at greater risk (32.0%) than men (16.3%; male/female odds ratio (OR) = 2.43, 95% confidence interval (CI) = 1.90-3.09). The prevalence of depression was higher among immigrants (30.4%, OR = 1.70, 95% CI = 1.36-2.13), bicultural participants (24.2%, OR = 1.66, 95% CI = 1.24-2.24), and less-acculturated participants (36.1%, OR = 2.95, 95% CI = 2.22-3.93) compared with U.S.-born (20.5%) and more-acculturated groups (16.1%). When adjustments for education, income, psychosocial, behavioral, and health-problem factors were made, the least-acculturated participants were at significantly higher risk of depression than highly acculturated Mexican Americans (OR = 1.56, 95% CI = 1.06-2.31). CONCLUSIONS: These findings are consistent with previously reported estimates of a higher prevalence of depression for older Mexican Americans than non-Hispanic Caucasians and African Americans and are the first to report the prevalence and risk of depression for older U.S.-born and immigrant Mexican Americans. The high prevalence of depression of the least acculturated group may be related to cultural barriers encountered by immigrants and less-acculturated older Mexican Americans and to poorer health status.     

Persistent infection, inflammation, and functional impairment in older Latinos

BACKGROUND: The objective of this study was to examine whether cytomegalovirus (CMV), herpes simplex virus type-1 (HSV-1), and C-reactive protein (CRP) are associated with functional impairment in older Latinos. METHODS: A cross-sectional analysis of a cohort study was conducted with a community-dwelling elderly population. The sample was a subset (N = 1559/1789) of participants in the Sacramento Area Latino Study on Aging (SALSA) ages 60-101 with available serum samples and functional impairment measures. Baseline serum samples were assayed for levels of immunoglobulin G antibodies to CMV and HSV-1 and for levels of CRP. Several measures were used to assess functional impairment, including activities of daily living (ADL), instrumental activities of daily living (IADL), and walking pace. RESULTS: CMV and CRP showed statistically significant graded associations with ADL functional impairment, even after controlling for age and gender. The relationship between CMV and ADL was slightly attenuated, and the confidence interval contained the null value when adjusted for total number of health conditions, body mass index, and household income. Only high levels of CRP were significantly related to ADL and IADL impairment even after adjusting for all other covariates. CONCLUSION: Inflammation is clearly linked to physical functioning among aging Latinos. This study also suggests a role for CMV infection in relation to ADL impairment. Further research examining the influence of infection, immune response, and inflammation on longitudinal trajectories of physical functioning is warranted.     

The effect of exercise training in symptomatic patients with grown-up congenital heart disease: a review

Introduction: The number of grown-up congenital heart disease (GUCH) patients is steadily increasing. Unfortunately, the majority of these patients suffer from late sequelae, with heart failure being the most common cause of death. Exercise training is beneficial and safe in patients with acquired heart failure, as well as in asymptomatic GUCH patients. However, its effect remains unknown in symptomatic GUCH patients. This could cause reticence on positive sports advice, with possible counterproductive effects.

Areas covered: A review of current literature was performed to evaluate the effect of exercise training in symptomatic (NYHA≥2) GUCH patients. The search yielded a mere three studies including symptomatic patients, and another six studies including also patients in NYHA 1 without making clear distinction between the NYHA subgroups.

Expert commentary: Suboptimal trial designs, low patient numbers, and homogeneity of investigated cardiac anomalies make this review insufficient to draw definite conclusions. However, all studies describe overall positive effects of exercise training in symptomatic GUCH patients in terms of exercise capacity and quality of life. There were no safety concerns. Larger-scaled, randomized controlled trials are needed to obtain certainty.     

Ethnic Background,Socioeconomic Status,and Problem Severity as Dropout Risk Factors in Psychotherapy with Youth

Background

Dropout from child and adolescent psychotherapy is a common phenomenon which can have negative consequences for the individual later in life. It is therefore important to gain insight on dropout risk factors.

Objective

Several potential risk factors [ethnic minority status, a lower socioeconomic status (SES), and higher problem severity] were analyzed in present study. Innovations are that these risk factors were examined for children and adolescents separately, and a distinction was made in termination status between referred patients, dropouts and completers.

Methods

For ethnic majority and minority outpatient children (age 5–11, n = 399) and adolescents (age 12–20, n = 352) problem severity, ethnic background, SES, and treatment termination status (completer, dropout, referral) were specified. Multinomial logistic regression models were used as main method of analysis.

Results

For children, a Moroccan/Turkish ethnicity and higher externalizing scores were risk factors for being referred. For adolescents, a Surinamese/Antillean ethnicity, being female, being older, and lower parental SES occupation levels were risk factors for dropout.

Conclusions

Different dropout risk profiles emerged for children versus adolescents, and for dropouts versus referrals. Also, it depended on the specific ethnic background whether ethnic minority status was a predictor for dropout, and the relationship between SES and termination status differed by whether parental SES occupation or parental SES education were used as SES indicator. Professionals should thus be aware of these potential risk factors for dropout or referral when treating children and adolescents.

     

Anastomotic pseudoaneurysm after aorto-coronary bypass grafting

A patient with a pseudoaneurysm at the site of the distal anastomosis of a saphenous vein coronary bypass graft is described. The aneurysm was resected. To our knowledge this is the first report of this complication after coronary bypass surgery.     

The quality of Intensive Care nursing before,during, and after the introduction of nurses without ICU-training

OBJECTIVE: The forecasted shortage of nurses specialized in intensive care seriously threatens the service level in the intensive care units (ICUs). This problem might partly be solved by introducing nurses without ICU experience who can provide basic nursing care to relieve the workload of the ICU nurses. This prospective controlled study was set up to determine whether such an introduction causes a significant shift in the quality of care. DESIGN: A prospective observational study was conducted to measure possible changes in the quality of care by examining the number of predefined nursing errors per patient with an observational instrument, the Critical Nursing Situation Index (CNSI). The CNSI was randomly applied during a preassessment period, an intervention period, and a postassessment period. During the intervention period, 16 full time equivalent nurses were employed with the assignment to assist the ICU nurses with basic care activities for 6 months. SETTING: The study was conducted in a 30-bed ICU at the Academic Medical Center in Amsterdam. ANALYSIS: The effect of the employment of nurses was expressed as the difference in the incidence of CNSI scores between the preassessment period and the intervention period on the basis of the relative risk ratios. The results of the comparison between the preassessment and the postassessment period were used to express the consistency of the measure. RESULTS: The researchers completed 600 CNSI observations in 256 patients in 162 days. Overall incidence rates during the preassessment (13%; 1539/12 222) and postassessment (14%; 1554/11 327) period were comparable, whereas the intervention period showed a diminished overall incidence of 9% (1019/11 395). The overall relative risk (95% CL) was 0.70 (0.56/0.86), indicating a significant risk reduction during the intervention period. CONCLUSION: The employment of nurses without ICU training improved the quality of care. This positive effect was primarily explained by the increase in available nursing time.     

Prophylactic pretreatment of mice with hematopoietic growth factors induces expansion of primitive cell compartments and results in protection against 5-fluorouracil-induced toxicity

The aim of this study was to expand the primitive and committed hematopoietic cell compartments in vivo in order to confer resistance of the blood cell forming system against the cytotoxic, cell cycle specific drug 5-fluorouracil (5-FU). Possible chemoprotective effects of such a pretreatment could result from increased numbers of hematopoietic cells, present before 5-FU administration. In addition, we hypothesized that an enhanced number of primitive and progenitor calls would result in a reduced cycling activity, ie, 5-FU sensitivity, of these same cells, due to normal physiological feedback loops. Administration of stem cell factor (SCF) plus interleukin-11 (IL-11) to mice was shown to result in expansion of the various immature cell compartments in marrow and, in particular, spleen. The total body content of the primitive cobblestone area forming cells (CAFC)-day 28 was increased to 140%, whereas the more committed cells (CAFC-day 7, erythroid and granuloid progenitors) were increased to 500%. This in vivo expansion resulted in a decreased 5-FU sensitivity of the hematopoietic system. In particular, mice that had received 5-FU 24 hours after discontinuation of growth factor pretreatment showed significantly less toxicity of committed cell stages. Compared with mice not pretreated, it appeared that in pretreated mice, 24 hours after 5-FU administration, the absolute number, but also the fraction of surviving CAFC, was much higher in both marrow and spleen. This was caused by a decrease in the cycling activity of all primitive cell subsets. To explore the possible use of this finding in a chemotherapeutic setting, we determined the interval between two subsequent doses of 5-FU (160 mg/kg) that was required to prevent drug- induced mortality. When control mice received a second dose of 5-FU 7, 10, or 14 days after the first, respectively 0%, 20%, and 80% survived. In contrast, 40% and 100% of mice that received SCF + IL-11 before the first dose of 5-FU, survived a second dose of 5-FU given respectively after 7 or 10 days. To assess whether chemoprotection in this setting could be ascribed to protection of the hematopoietic system, we transplanted a high number of normal bone marrow cells (sufficient to compensate for any hematopoietic deficiency) to normal and pretreated mice after they had been administered 2 doses of 5-FU, given 7 days apart. Bone marrow transplantation (BMT) could only rescue 50% of mice not pretreated, showing that a significant part of the mortality was because of nonhematologic toxicity. However, a BMT given to growth factor pretreated mice saved all mice, indicating that in this setting SCF + IL-11 had additional protective effects on cell systems other than hematopoiesis. In conclusion, our study showed fundamental knowledge about the behavior of primitive cells in vivo and has shown that manipulation of these and other cell compartments with appropriate growth factors may confer resistance against cytotoxic drugs.     

The influence of co-morbidity on health-related quality of life in asthma and COPD patients

This study examines the association between somatic co-morbidity and both general and disease-specific health-related quality of life (HRQoL) in patients with asthma and chronic obstructive pulmonary disease (COPD). A cross-sectional analysis was done among 161 COPD patients and 395 asthma patients, aged 40-75 years, recruited from general practice. In the total study population, 47% had no, 32% had one, and 21% had two or more somatic co-morbid conditions, with no significant differences between asthma and COPD patients. Co-morbidity appeared to be associated with poor disease-specific HRQoL in asthma [odds ratio (OR) = 2.08 (1.37-3.18)] and with poor general HRQoL in asthma [OR = 2.96 (1.93-4.53)] and COPD [1.81 (0.91-3.60)] patients. Poorest HRQoL was found in patients with more than one co-morbid condition. Cardiac disease and hypertension were associated with poor disease-specific HRQoL in asthma. Of all co-morbid conditions, musculoskeletal disorders were most strongly associated with poor general HRQoL. Cardiac disease was found to be associated with general and disease-specific HRQoL in asthma but not in COPD. In studies on patients with asthma or COPD aged 40-75 years, co-morbidity should be treated as a determinant of HRQoL.     

Early childhood internalizing problems,externalizing problems and their co-occurrence and (mal)adaptive functioning in emerging adulthood: a 16-year follow-up study

Purpose

A vast amount of studies suggest that internalizing or externalizing problems are related to individual functioning, and often co-occur. Yet, a focus on their additive and interactive effects is scarce. Furthermore, most research has focused on a limited number of developmental domains and mostly on maladaptive functioning. Therefore, the current prospective study examined whether early childhood (ages 4–8) internalizing and externalizing problems and their interaction were related to a broad range of (mal)adaptive functioning outcomes in emerging adulthood (ages 20–24).

Methods

Data from the Flemish Study on Parenting, Personality and Development were used. At Time 1 (1999) mothers of 374 children (45% boys) and fathers of 357 children (46% boys) rated internalizing and externalizing problems through the Child Behavior Checklist. Outcomes in emerging adulthood were measured through self-reports 16 years later across the following domains: psychological functioning, social functioning, work, physical health, and self-concept.

Results

Early externalizing problems were related to maladaptive outcomes on the psychological and social domains. With regard to adaptive functioning, externalizing problems were associated with lower satisfaction regarding general health on the physical domain. Early internalizing problems were not associated with any emerging adulthood outcomes. The interaction of (father reported) internalizing and externalizing problems was related to aggressive behavior.

Conclusion

Early childhood externalizing problems were associated with maladaptive and adaptive functioning over a time span of 16 years. The results add to studies on the implementation of prevention and intervention programs in early childhood and to the value for developing personalized interventions.
