Making the decision to donate eyes: Perspectives from the families of the deceased in Madurai,India

Purpose:To identify factors affecting family members'' decision whether to donate eye organs.Methods:A community-based case-control study based on in-home interviews with families of deceased individuals who had or had not donated eye organs, in Madurai district, Tamil Nadu, India. Data collected were knowledge and awareness of eye donations, whether the deceased individual had expressed or pledged willingness to donate, and family members'' attitudes and willingness to donate their own eye organs.Results:Seventy-six families of donors and 256 families of non-donors completed the survey. Multivariable analysis showed that the following variables were significantly associated with a donation: age, whether the deceased had registered for eye donation, pre-expressed willingness of deceased to donate, whether family members personally know beneficiaries of eye donations, and higher score on a scale evaluating knowledge and awareness about eye donation. The majority of donors'' families (71%) had been encouraged by someone to donate. Among non-donor families, a substantially larger fraction (52.8%) indicated they would have donated had someone reminded or encouraged them to do so, in comparison with those who indicated lack of awareness or knowledge (14.5%).Conclusion:Community programs are likely to be effective if they encourage individuals to pledge their eyes or express their willingness to donate their eyes to family members in advance of death; they increase public awareness of the value of eye donation. A friend, family member, neighbor or counselor approaching bereaved families and having a dialogue about eye donation would substantially increase the probability of a decision to donate.     

Incisional hernia after liver transplantation: risk factors and health‐related quality of life

The aim of this cross‐sectional study was to analyze the incidence of incisional hernia after liver transplantation (LT), to determine potential risk factors for their development, and to assess their impact on health‐related quality of life (HRQoL). Patients who underwent LT through a J‐shaped incision with a minimum follow‐up of three months were included. Follow‐up was conducted at the outpatient clinic. Short Form 36 (SF‐36) and body image questionnaire (BIQ) were used for the assessment of HRQoL. A total of 140 patients was evaluated. The mean follow‐up period was 33 (SD 20) months. Sixty patients (43%) were diagnosed with an incisional hernia. Multivariate analysis revealed surgical site infection (OR 5.27, p = 0.001), advanced age (OR 1.05, p = 0.003), and prolonged ICU stay (OR 1.54, p = 0.022) to be independent risk factors for development of incisional hernia after LT. Patients with an incisional hernia experienced significantly diminished HRQoL with respect to physical, social, and mental aspects. In conclusion, patients who undergo LT exhibit a high incidence of incisional hernia, which has a considerable impact on HRQoL. Development of incisional hernia was shown to be related to surgical site infection, advanced age, and prolonged ICU stay.     

Collagen type III alpha 1 polymorphism (rs1800255, COL3A1 2209 G>A) assessed with high-resolution melting analysis is not associated with pelvic organ prolapse in the Dutch population

Introduction and hypothesis

The rs1800255, COL3A1 2209 G>A polymorphism in the alpha 1 chain of collagen type III has been associated with an increased risk of pelvic organ prolapse (POP). In one of our previous studies however, polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) misdiagnosed rs1800255, COL3A1 2209 G>A in 6 % of cases. The high-resolution melting (HRM) analysis on the contrary obtained a 100 % accordance for this specific polymorphism and was used in the present study to validate this risk factor for POP.

Methods

In this case–control study, women with and without symptoms of POP were included and compared. DNA was extracted from blood samples. HRM analysis was used to assess for the presence of the homozygous rs1800255. Groups were compared using the Pearson chi-square, Mann–Whitney, and t tests. The discrepancy between HRM and PCR-RFLP results was investigated using PCR-RFLP results available from our previous study.

Results

The study included 354 women: 272 patients with POP and 82 controls; 18 (7 %) cases versus 3 (4 %) controls had a homozygous rs1800255, COL3A1 2209 G>A polymorphism (odds ratio 1.9, 95 % confidence interval 0.5–6.9, compared to the wild type), and thus no association between POP and the homozygous polymorphism could be demonstrated. A discrepancy between HRM and PCR-RFLP results was found in 8 % of the samples.

Conclusions

The previously found statistically significant association between the rs1800255, COL3A1 2209 G>A polymorphism as measured with PCR-RFLP and POP could no longer be demonstrated. This raises concerns regarding the results of other association studies using PCR-RFLP.     

Development and psychometric properties of the Maastricht Personal Autonomy Questionnaire (MPAQ) in older adults with a chronic physical illness

Purpose

To develop and test the Maastricht Personal Autonomy Questionnaire (MPAQ), an instrument measuring personal autonomy of older adults with a chronic physical illness in accordance with their experience of autonomy. Achievement of personal autonomy is conceptualized as correspondence between the way people’s lives are actually arranged and the way people want to arrange their lives.

Methods

A field test was conducted in three waves (n = 412, n = 125 and n = 244) among a random sample of people older than 59 years with either chronic obstructive pulmonary disease or diabetes mellitus. Construct validity, reproducibility and responsiveness were evaluated.

Results

The MPAQ entailing 16 items consists of three scales: degree of (personal) autonomy, working on autonomy and dilemmas. Construct validity was largely supported by confirmatory factor analysis and correlations between the MPAQ and other instruments. Intraclass correlation coefficients ranged from 0.61 to 0.80 and SRDs_group from 0.10 to 0.13. Mean change was larger (0.54) than was SRD_group (0.11) in patients who had deteriorated, but smaller in patients who had improved (0.07).

Conclusions

The MPAQ has good content and construct validity and moderate reproducibility. Responsiveness is weak, although better for deterioration than for improvement.     

A prospective survey of risk factors in young adults with arterial occlusive disease

Few studies have presented a thorough analysis of young adults with symptoms of arterial occlusive disease. To learn more about the possible risk factors of vascular disease playing a role in these young patients, we have reviewed all patients of 45 years of age and younger with symptoms of arterial occlusive disease who had been referred to our department between 1978 and 1987. Thirty-seven patients (28 males and 9 females) were included in the study. The mean age at which the first symptoms occurred was 34 years. Most patients presented with chronic arterial obliterations of the lower extremities (31/37, 84%). In addition, 4 patients showed signs of ischaemic heart disease. A strongly positive family history of arteriosclerosis was obtained from 13 patients (35%). Hypertension was present in 7 patients (19%), diabetes in three (8%) and nicotine abuse was found in 27 patients (73%). Fifty-four percent of the patients (20/37) had undergone vascular reconstructive surgery, 19% (7/37) underwent transluminal dilatation, and 3 had had subsequent treatment of newly developed lesions. For this study, all patients were recalled to the outpatient clinic. A complete case history was taken followed by a physical examination and ECG. Laboratory examinations were performed to analyse parameters of: (a) coagulation; (b) fibrinolysis; (c) fat- and (d) methionine metabolism. Clear-cut laboratory abnormalities were found in 33 patients (33/37, 89%). Coagulation parameters were abnormal in 11 patients (30%) (protein S deficiency: 3 pts). Fibrinolysis was impaired in 15 patients (40%).(ABSTRACT TRUNCATED AT 250 WORDS)     

The roles of matrix polymer crystallinity and hydroxyapatite nanoparticles in modulating material properties of photo-crosslinked composites and bone marrow stromal cell responses

Two poly(?-caprolactone fumarate)s (PCLFs) with distinct physical properties have been employed to prepare nanocomposites with hydroxyapatite (HA) nanoparticles via photo-crosslinking. The two PCLFs are PCLF530 and PCLF2000, named after their precursor PCL diol with molecular weight of 530 and 2000 g mol^?1, respectively. Crosslinked PCLF530 is amorphous while crosslinked PCLF2000 is semi-crystalline with a melting temperature (T_m) of ～40 °C and a crystallinity of 40%. Consequently, the rheological and mechanical properties of crosslinked PCLF2000 are significantly greater than those of crosslinked PCLF530. Structural characterizations and physical properties of both series of crosslinked PCLF/HA nanocomposites with HA compositions of 0%, 5%, 10%, 20%, and 30% have been investigated. By adding HA nanoparticles, crosslinked PCLF530/HA nanocomposites demonstrate enhanced rheological and mechanical properties while the enhancement in compressive modulus is less prominent in crosslinked PCLF2000/HA nanocomposites. In vitro cell attachment and proliferation have been performed using rat bone marrow stromal cells (BMSCs) and correlated with the material properties. Cell attachment and proliferation on crosslinked PCLF530/HA nanocomposite disks have been enhanced strongly with increasing the HA composition. However, surface morphology and surface chemistry such as composition, hydrophilicity, and the capability of adsorbing protein cannot be used to interpret the cell responses on different samples. Instead, the role of surface stiffness in regulating cell responses can be supported by the correlation between the change in compressive modulus and BMSC proliferation on these two series of crosslinked PCLFs and PCLF/HA nanocomposites.     

Material deprivation and health-related dysfunction in older Dutch people: findings from the SMILE study.

BACKGROUND: Even in generally wealthy Western countries material deprivation and poverty are not uncommon. There is, however, little data on the prevalence of material deprivation and its associations with health-related dysfunction in older people. METHODS: Cross-sectional data from the SMILE study were used to examine the prevalence of material deprivation and the associations between material deprivation and health-related dysfunction in persons aged 55 years and older (n > 4000). Material deprivation was measured with a comprehensive questionnaire assessing seven subdomains referring to current and anticipated financial problems and poverty in childhood. Health-related dysfunction was measured using the SF36-based physical and mental components. In addition, self-reported heart disease was examined as an indicator of health-related dysfunction as well. RESULTS: Almost 29% of subjects experienced at least one financial problem. Those reporting material deprivation had more than twice the risk of physical (OR = 2.22; 95% CI: 1.72-2.86) and mental (OR = 2.34; 95% CI: 1.84-2.97) dysfunction compared with non-deprived persons. A slightly weaker association was found when self-reported heart disease was used as an outcome variable (OR = 1.74; 95% CI: 1.40-2.15). Although odds ratios were generally higher for diseased older persons, no significant interaction effect between chronic disease and material deprivation subscales was found. CONCLUSIONS: Material deprivation in the Netherlands is not uncommon and is strongly related to both mental and physical dysfunction, and therefore needs further attention in public health policy. Longitudinal research is necessary to clarify the causal nature of our results and to develop appropriate interventions.     

Health burden in the Netherlands due to infection with thermophilic Campylobacter spp

Infection with thermophilic Campylobacter spp. usually leads to an episode of acute gastroenteritis. Occasionally, more severe diseases may be induced, notably Guillain Barré syndrome and reactive arthritis. For some, the disease may be fatal. We have integrated available data in one public health measure, the Disability Adjusted Life Year (DALY). DALYs are the sum of Years of Life Lost by premature mortality and Years Lived with Disability, weighted with a factor between 0 and 1 for the severity of illness. The mean health burden of campylobacter-associated illness in the Dutch population in the period 1990-5 is estimated as 1400 (90% CI 900-2000) DALY per year. The main determinants of health burden are acute gastroenteritis (440 DALY), gastroenteritis related mortality (310 DALY) and residual symptoms of Guillain-Barré syndrome (340 DALY). Sensitivity analysis demonstrated that alternative model assumptions produced results in the above-mentioned range.
