Italian translation, cultural adaptation, and validation of the Intermittent Catheterization Acceptance Test (I-CAT)

Aims

The purpose of the present study was to translate and culturally adapt the Intermittent Catheterization Acceptance Test (I-CAT) for Italian individuals with spinal cord injury and spina bifida and to measure its psychometric properties.

Methods

Consent from the authors of I-CAT was received, and then, following international guidelines, it was culturally adapted to Italian. The included participants adults who practice self-catheteri-zation. In order to evaluate criterion validity, the Qualiveen-30, Spinal Cord Independence Measure (SCIM-self reported), and the Moorong self-efficacy scale (MSES) were administered together. Test-retest reliability was assessed administering the I-CAT a second time within a week. Following the COSMIN checklist, psychometric properties were evaluated.

Results

All translated items resulted identical or similar to the original versions. Internal consistency, evaluated on 34 individuals, showed values of Cronbach's alpha of 0.889, test-retest reliability was evaluated through the intraclass correlation coefficient with values of 0.96. Statistically significant correlation between the I-ICAT and Qualiveen were found through Pearson's correlation coefficient and Spearman's Correlation Coefficient for criterion validity.

Conclusions

The Italian validation of I-CAT allows Italian professionals to investigate psychological barriers linked with self-catheterization in people with urinary tract dysfunction before learning about aseptic Intermittent Self Catheterization (IC) and improving patients' acceptance of it. This tool can also be used as follow-up after the training of intermittent self-catheterization techniques. Finally, it is an important tool for medical research.

Portal venous versus systemic venous drainage of pancreas grafts: impact on long-term results

Portal venous (PV) and systemic venous (SV) drainage methods are used in pancreas transplantation. The impact of the reconstruction technique on long-term outcome remains unclear. We compared the efficacy and side effects of both methods in 192 recipients who received synchronous pancreas kidney transplants between November 1995 and November 2007. SV and PV drainage were used in 147 and 45 cases, respectively. Pancreas function was determined by hemoglobin A1c levels and annual oral glucose tolerance test. Serum creatinine assessed kidney function. Serum lipid (low-density lipoprotein, high-density lipoprotein and cholesterol) levels and body mass index were measured annually. Patient and graft survival were calculated by log-rank analysis. Pancreas survival for SV versus PV patients was similar after 5 years (81.8% vs. 75.5%) and 10 years (65.1% vs. 60%; p = NS). Similarly, no difference was detected between the groups regarding kidney survival after 5 years (92.9% vs. 84.4%) and 10 years (81.6% vs. 75.5%; p = NS). Patient survival did not differ at 5 years (94.3% vs. 88.8%) and 10 years (85.1% vs. 84.4%; p = NS). Pancreas and kidney function and the lipid profiles were similar in both groups. SV and PV drainage of pancreas grafts offer similar long-term graft survival and function and choice of method should remain the preference of the surgeon.

Trabecular bone deficits among Vietnamese immigrants

SUMMARY

Compared to white women, lower areal bone mineral density (aBMD) in middle-aged Vietnamese immigrants is due to reduced trabecular volumetric bone mineral density (vBMD), which in turn is associated with greater trabecular separation along with lower estrogen levels.

INTRODUCTION

The epidemiology of osteoporosis in Asian populations is still poorly known, but we previously found a deficit in lumbar spine aBMD among postmenopausal Southeast Asian women, compared to white women, that persisted after correction for bone size. This issue was revisited using more sophisticated imaging techniques.

METHODS

Twenty Vietnamese immigrants (age, 44-79 years) were compared to 162 same-aged white women with respect to aBMD at the hip, spine and wrist, vBMD at the hip and spine by quantitative computed tomography and vBMD and bone microstructure at the ultradistal radius by high-resolution pQCT. Bone turnover and sex steroid levels were assessed in a subset (20 Vietnamese and 40 white women).

RESULTS

The aBMD was lower at all sites among the Vietnamese women, but femoral neck vBMD did not differ from middle-aged white women. Significant differences in lumbar spine and ultradistal radius vBMD in the Vietnamese immigrants were due to lower trabecular vBMD, which was associated with increased trabecular separation. Bone resorption was elevated and bone formation depressed among the Vietnamese immigrants, although trends were not statistically significant. Serum estradiol was positively associated with trabecular vBMD in the Vietnamese women, but their estrogen levels were dramatically lower compared to white women.

CONCLUSIONS

Although reported discrepancies in aBMD among Asian women are mainly an artifact of smaller bone size, we identified a specific deficit in the trabecular bone among a sample of Vietnamese immigrants that may be related to low estrogen levels and which needs further study.

Variations in bone density among persons of African heritage

The epidemiology of bone loss in populations of African heritage is still poorly known. We compared a convenience sample of 47 African-American (AA) residents of Rochester, Minnesota (32 women, 15 men) and 66 recent immigrants from Somalia (all women) with 684 white subjects (349 women, 335 men) previously recruited from an age-stratified random sample of community residents. Areal bone mineral density (BMD, g/cm(2)) and volumetric bone mineral apparent density (BMAD, g/cm(3)) were determined for lumbar spine and proximal femur using the Hologic QDR 2000 for white subjects and the QDR 4500 for the others; the instruments were cross-calibrated from data on 20 volunteers. Lumbar spine BMD was 18% higher in AA ( p<0.001) and 4% lower in Somali ( p = 0.147) than white women. Femoral neck BMD was 27% higher in AA women but also 11% greater in Somali women (both p<0.001) compared with whites. Lumbar spine BMD was 6% higher ( p = 0.132) and femoral neck BMD 21% higher ( p<0.001) in AA than white men. No Somali men were studied. After correcting for bone size differences, both lumbar spine ( p<0.01) and femoral neck BMAD ( p<0.001) were greater for Somali than white women, but the difference between Somali and AA women persisted. Lumbar spine and femoral neck BMAD values also remained significantly greater for AA women (both p<0.001) and men ( p<0.05; p<0.001) compared with whites. Weight was associated with BMAD at both skeletal sites in all groups, but adjustment for differences in weight did not reduce the discrepancy in BMAD values between Somali and AA women or between the latter group and whites. This heterogeneity among different ethnic groups of African heritage may provide an opportunity for research to better explain race-specific differences in bone metabolism.

Bone density in an immigrant population from Southeast Asia

The epidemiology of bone loss in populations of Asian heritage is still poorly known. This study compared the skeletal status of a convenience sample of 396 Southeast Asian immigrants (172 Vietnamese, 171 Cambodians and 53 Laotians) residing in Rochester, Minnesota in 1997 with 684 white subjects previously recruited from an age-stratified random sample of community residents. Areal bone mineral density (BMD, g/cm2) and volumetric bone mineral apparent density (BMAD, g/cm3) were determined for lumbar spine and proximal femur using the Hologic QDR 2000 instrument for the white population and the QDR 4500 for Southeast Asian subjects; the machines were cross-calibrated from data on 20 volunteers. Lumbar spine BMD was 7% higher in white than Southeast Asian women (p < 0.001), and similar results were observed for the femoral neck; lumbar spine BMD was 12% higher in white than nonwhite men (p < 0.001). Race-specific discrepancies were reduced by calculating BMAD: for premenopausal women, lumbar spine and femoral neck differences between whites and Southeast Asians were eliminated; for postmenopausal women the lumbar spine differences persisted (p < 0.0001), while femoral neck BMAD was actually higher for Southeast Asians. There were no race-specific differences in femoral neck BMAD among men of any age (p = 0.312), but lumbar spine BMAD was less for younger (p = 0.042) but not older (p = 0.693) Southeast Asian men. There were differences among the Southeast Asian subgroups, but no clear pattern emerged. Predictors of lumbar spine BMAD in Southeast Asian women were age (p < 0.001), weight (p = 0.015) and gravidity (p = 0.037). Even after adjusting for bone size using BMAD, 32% and 9% of Southeast Asian women and men, respectively, would be considered to have osteoporosis at the femoral neck and 25% and 4%, respectively, at the lumbar spine. These findings indicate a need for culturally sensitive educational interventions for Southeast Asians and for physicians to pursue diagnosis and treatment to prevent osteoporosis-related disabilities in this population.

Delivery rates for preventive services in 44 midwestern clinics

OBJECTIVE

To determine the rates at which private primary-care clinics are recommending blood pressure and cholesterol measurement, smoking cessation, clinical breast examination, screening mammography, Papanicolaou testing, and influenza and pneumococcus immunizations.

MATERIAL AND METHODS

We conducted a mail survey of 7,997 randomly selected patients from 44 primary-care clinics in and around Minneapolis-St. Paul, Minnesota, of whom 6,830 (85.4%) completed the questionnaire on preventive services delivery rates. The responses were analyzed statistically, including stratification by reason for the clinic visit.

RESULTS

On the average, about two-thirds of the patients in each clinic reported being up-to-date on preventive services before their clinic visit; an exception was pneumococcus immunization (mean rate, 33%). Except for blood pressure and smoking cessation advice, less than 30% of patients who were not up-to-date on a preventive service were offered it if the clinic visit was for a reason other than a checkup or physical examination. For patients who said that they saw their physician for a checkup or physical examination, the rate was more than 50% only for Papanicolaou smear. In contrast, nearly all responding practitioners agreed that each of the eight preventive services was very important or important.

CONCLUSION

Preventive services consensus goals are not being met, even for patients who report that their clinic visit was for a checkup or physical examination. This finding suggests that it may be necessary to develop clinical systems that support and enable the delivery of preventive services.

Zygote intrafallopian transfer (ZIFT): evaluation of 42 cases

ZIFT offers the embryologic follow-up of fertilization combined with the advantage of natural tubal transport of embryos to the uterus. Comparing ZIFT pregnancy data to the patients' failed IVF-ET cycles, it is premature to conclude that these pregnancies were exclusively due to the early intrafallopian transfer of zygotes, but the results are encouraging.
