Metabolic syndrome is not associated with erectile dysfunction in apparently healthy men

AIMS

To investigate whether metabolic syndrome (MetS) is associated with erectile dysfunction (ED) among apparently healthy men when depressive symptoms and serum testosterone levels are taken into account.

METHODS

A study population of 549 men at risk for cardiovascular disease or type 2 diabetes was drawn from the participants of a population survey, the Harmonica Project. MetS was diagnosed with the United States National Cholesterol Education Program Third Adult Treatment Panel (ATPIII) 2005 definition, the International Diabetes Federation (IDF) 2005 definition and the Harmonization 2009 definition. ED was evaluated by the International Index of Erectile Function (IIEF-5) questionnaire. Depressive symptoms were assessed with Beck's Depression Inventory (BDI).

RESULTS

Of the 549 men (mean age 58.4 ± 6.7 years), 56.5 % reported ED. The prevalence of MetS was 48.6%, 35.5%, and 50.6% according to the IDF, the ATPIII, and the Harmonization criteria, respectively. We found no difference in the prevalence of ED between men with or without MetS. In a multivariate analysis, age, presence of depressive symptoms and lower education were significant predictors of ED.

CONCLUSIONS

The prevalence of ED is quite high even in apparently healthy men. Depressive symptoms are a critical component to consider in men suffering from ED.

Effect of administrative information on visit rate of frequent attenders in primary health care: ten-year follow-up study

Background

Frequent attenders (FAs) use a disproportionately large share of the resources of general practitioners (GPs) working in primary healthcare centres. The aim of this study was to estimate the proportion of FAs among all patients in the primary health care centres of a medium-sized city in Finland, and to examine whether providing GPs with administrative information about their frequent attenders (names and numbers of visits per year) can reduce the number of FAs and the frequency of their visits.

Methods

Statistic data on all GP visits (n = 1.8 million) to 11 public healthcare centres in one city were collected from the electronic patient records covering the period from 2001 to 2010. A FA-patient was defined as a person who made10 or more visits to GPs during one year. The baseline situation in 2001 was compared with the situation in 2006 after administrative information had been provided three times to all GPs working in the healthcare centres. Poisson’s regression analysis was used, and FA numbers and consultation rates in the years 2002–2005 were compared with the year 2006; figures for 2006 were also compared with those for the follow-up period 2007–2010.

Results

During the years 2001–2006, the proportion of visits of FA-patients fell overall from 9.1 to 8.5%, a decline of 0.6% (p < 0.0001). This reduction was equivalent to an annual work load of two GPs in the study center. The proportion of visits of FA patients increased again in the follow-up period (2007–2010), when administrative information was no longer provided.

Conclusion

When GPs are provided with information on the number and names of their FA-patients, the annual rate of FA visits to GPs drops significantly. The method is simple and repeatable. However, without a control group of GPs who have not received such information, it is impossible to assess if the intervention was the only circumstance affecting the reduction in FA consultation rates.

Erectile dysfunction cannot be used in primary screening of pre-diabetes

We hypothesized that erectile dysfunction is associated with impaired fasting glucose and impaired glucose tolerance and could be used in primary screening of pre-diabetes. Although erectile dysfunction is known to be closely associated with diabetes, we demonstrate that it is not associated with pre-diabetes in 926 apparently healthy men.

Correlation between acoustic rhinometry and visual analogue scale in children with no nasal symptoms: a prospective cohort study

OBJECTIVES

Acoustic rhinometry is an objective tool to evaluate nasal obstruction. The aim of this study was to evaluate the usefulness of visual analogue scale (VAS) as a subjective tool for nasal obstruction and the correlation between acoustic rhinometry and VAS in children with no nasal symptoms.

DESIGN

Unilateral acoustic values and VAS were measured at baseline and after decongestion of the nose.

SETTING

Tertiary academic hospital.

PARTICIPANTS

The study included 124 children aged between 7 and 14 years with no permanent nasal symptoms.

RESULTS

At baseline, the mean minimal cross-sectional area on the right side was 0.392 cm(2) (sd 0.094), and on the left side 0.360 cm(2) (sd 0.093), whereas the mean VAS on the right side was 7.43 (sd 2.50) and on the left side 6.81 (sd 3.01). After decongestion, the mean minimal cross-sectional area on the right and left sides were 0.421 cm(2) (sd 0.087) and 0.373 cm(2) (sd 0.11), respectively, whereas the mean VAS on the right and left sides were 8.77 (sd 2.02) and 8.54 (sd 2.14), respectively. At baseline, a significant correlation was found between VAS and minimal cross-sectional area, but no correlation was found between VAS and acoustic values after decongestion.

CONCLUSIONS

We conclude that VAS shows potential as a subjective tool to investigate nasal obstruction in children over 7 years of age. There was a correlation between VAS and acoustic rhinometry in children with no nasal symptoms at baseline. No correlation was found in children with decongested normal nasal airways.

Reference values for acoustic rhinometry in children at baseline and after decongestion

BACKGROUND

Acoustic rhinometry is widely used for objective evaluation of nasal dimensions. However, there is a lack of agreement on the normative values in children at baseline, and especially after decongestion. The purpose of this study was to determine the reference values for Finnish school children for acoustic rhinometry in non-decongested and decongested noses, and to find out which of the potential predictors (age, sex, body surface area (BSA) and height) would be the most useful one(s).

METHODOLOGY

The study included 124 children aged between 6.90 and 13.84 years with no permanent nasal symptoms.

RESULTS

At baseline, the mean total minimal cross-sectional area (MCA) was 0.752 cm2, and the mean total volume between 0 - 3 cm (VOL) was 4.00 cm3. After decongestion, the total MCA was 0.794 cm2, and the VOL was 4.38 cm3. There was a significant correlation between MCA and age, between VOL and height, and between VOL and BSA at baseline and after decongestion. We found no difference in the values between boys and girls.

CONCLUSIONS

We conclude that acoustic rhinometry is a suitable objective method to monitor the changes in mucosal swelling and nasal obstruction in children. Age and height or BSA of a child can be suggested as predictive factors.

The change in child self-assessed and parent proxy-assessed Health Related Quality of Life (HRQL) in early adolescence (age 10-12)

AIMS

To examine the development of self-assessed and parent proxy-assessed health related quality of life (HRQL) in pre-adolescent schoolchildren.

METHODS

The population (n = 1,346) consisted of the total cohort of children starting 4th grade (age 10) in 2004 in primary schools in a Finnish city of 175,000 inhabitants. HRQL was assessed using the Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0). The baseline study was conducted in 2004 (child age 10) and follow-up in a panel setting in 2006 (child age 12). The response rate for the children was 80% (n = 1,094) in 2004 and 85% (n = 1,139) in 2006. The response rate for children having responded both in 2004 and 2006 was 73% (n = 986). For parents of the children, one parent participated in the parents' survey (n = 999 in 2004, n = 888 in 2006).

RESULTS

HRQL scores increased significantly in the two-year follow up (child t = 10.16-5.95, p < 0.0001, parent-proxy t = 6.35-2.76, p < 0.0001-0.006). Correlation between baseline and follow-up assessments was significant (child r = 0.4-0.5, p < 0.0001, parent r = 0.47-0.57, p < 0.0001). The correlation between baseline HRQL and change was negative (child r =-0.67 to -0.56, p < 0.0001, parent r =-0.62 to -0.46, p < 0.0001). Correlation between child and parent assessments increased from baseline (r = 0.20-0.39, p < 0.0001) to follow up (r = 0.3-0.42, p < 0.0001).

CONCLUSIONS

Child-assessed and parent proxy-assessed HRQL scores increase, suggesting HRQL improves, when children grow from age 10 to age 12. Baseline HRQL may not strongly predict future HRQL in early adolescence. The correlation between child self-assessment and parent proxy-assessment is fragile.

Effect of a risk-based multifactorial fall prevention program on the incidence of falls

OBJECTIVES

To evaluate the effects of a multifactorial fall prevention program on falls and to identify the subgroups that benefit the most.

DESIGN

Randomized controlled trial.

SETTING

Community-dwelling subjects who had fallen at least once during the previous 12 months.

PARTICIPANTS

Five hundred ninety-one subjects randomized into intervention (IG) (n=293) and control (CG) (n=298) groups.

INTERVENTION

A multifactorial 12-month fall prevention program.

MEASUREMENTS

Incidence of falls.

RESULTS

The intervention did not reduce the incidence of falls overall (incidence rate ratio (IRR) for IG vs CG=0.92, 95% confidence interval (CI)=0.72-1.19). In subgroup analyses, significant interactions between subgroups and groups (IG and CG) were found for depressive symptoms (P=.006), number of falls during the previous 12 months (P=.003), and self-perceived risk of falling (P=.045). The incidence of falls decreased in subjects with a higher number of depressive symptoms (IRR=0.50, 95% CI=0.28-0.88), whereas it increased in those with a lower number of depressive symptoms (IRR=1.20, 95% CI=0.92-1.57). The incidence of falls decreased also in those with at least three previous falls (IRR=0.59, 95% CI=0.38-0.91) compared to those with one or two previous falls (IRR=1.28, 95% CI=0.95-1.72). The intervention was also more effective in subjects with high self-perceived risk of falling (IRR=0.77, 95% CI=0.55-1.06) than in those with low self-perceived risk (IRR=1.28, 95% CI=0.88-1.86).

CONCLUSION

The program was not effective in reducing falls in the total sample of community-dwelling subjects with a history of falling, but the incidence of falls decreased in participants with a higher number of depressive symptoms and in those with at least three falls.

The effects of multifactorial fall prevention on depressive symptoms among the aged at increased risk of falling

OBJECTIVES

The aim was to determine the effects of multifactorial fall prevention on depressive symptoms among aged Finns at increased risk of falling.

METHODS

This study is part of a multifactorial fall prevention trial with a randomised controlled design implemented in the town of Pori, western Finland. The study population consisted of ambulatory, 65-year-old or older Finns, with moderate or high cognitive and physical abilities who had fallen at least once during the previous 12 months. The participants (n=591) were randomised into a risk-based multifactorial fall prevention programme (intervention group, IG) or into a one-time counselling group (control group, CG). The 1-year intervention included individual geriatric assessment followed by treatment recommendations, individual guidance regarding fall prevention, physical exercise in small groups twice a month, psychosocial group activities and lectures once a month, home-exercises and home hazard assessment. The outcome, depressive symptoms, was measured by the 30-item Geriatric Depression Scale (GDS).

RESULTS

The full GDS data with no missing items were available for 464 persons. A significant decrease in depressive symptoms during the 12-month intervention was found both in IG and in CG, but the difference in change was not significant (p=0.110). However, a significant difference in change between the groups was found among men and older subjects (>or=75) in favour of the IG.

CONCLUSION

Multifactorial fall prevention had no effects on depressive symptoms among the community-dwelling aged. However, men and older participants benefited from the intervention.

Effect of physician-staffed helicopter emergency medical service on blunt trauma patient survival and prehospital care

OBJECTIVE

The aim of the study was to assess the immediate and long-term effect of a helicopter emergency physician giving advanced life support on-scene compared with conventional load and go principle in urban and rural settings in treating blunt trauma patients.

METHODS

In a retrospective study, 81 blunt trauma patients treated prehospitally by a physician-staffed helicopter emergency medical service were compared with 77 patients treated before the era of the helicopter emergency medical service. The data were collected in the prehospital and hospital files and a questionnaire was sent to the survivors 3 years after the trauma.

RESULTS

The physicians treated the patients more aggressively (gave drugs, intubated and cannulated) and had the patients transported directly to a university hospital. The given treatment did not delay arrival at the hospital. No statistically significant difference was found, but a trend (P = 0.065) to lower survival in the helicopter emergency medical service group. Almost half of the deaths in the helicopter emergency medical service group and none in the control group, however, occurred in the emergency department. No difference was found 3 years later between the groups in the health-related quality of life or decrease in the income owing to the accident.

CONCLUSION

The physicians treated the patients more aggressively, but it did not delay the arrival at the hospital. A beneficial effect of this aggressive treatment or direct transport to a university hospital could not be seen in the immediate physiological parameters or later health-related quality of life. The physician-staffed helicopter emergency medical service was not beneficial to blunt trauma patients in this setting.

Associations of Thyroid-Stimulating Hormone and Free Thyroxine Concentrations with Health and Life Satisfaction in Elderly Adults

OBJECTIVE

To analyze associations between thyroid-stimulating hormone (TSH) and free thyroxine (FT4 concentrations and life satisfaction, symptoms, self-rated health, and common neuropsychiatric diseases (depression or dementia) in a community-dwelling elderly population to provide evidence whether to decrease the upper reference limit for TSH or the optimal TSH target in levothyroxine treatment in older adults.

METHODS

In this cross-sectional study, we determined TSH and FT4 concentrations in a thyroid disease-free population of 502 men (median age, 71 years) and 584 women (median age, 73 years) and in a patient group of 49 women (median age, 75 years) with primary hypothyroidism who were stable users of thyroxine treatment. Life satisfaction, self-rated health, depression, and dementia were assessed with specific questions and with tools such as the Self-report Depression Scale and the Mini-Mental State Examination. Independent variables were dichotomized, and associations of these variables with TSH and FT4 levels were assessed in the thyroid disease-free population. Levels of TSH and FT4 in thyroid disease-free women and in women treated with thyroxine were also compared.

RESULTS

After age adjustment, there were no associations between TSH levels and self-rated health, life satisfaction, or most symptoms in the thyroid disease-free population. No associations were found between diagnosed depression or Mini-Mental State Examination results and levels of TSH and FT4. Dementia was associated with higher FT4 concentration in men. Although women treated with thyroxine had TSH levels that were higher than thyroid disease-free women, there were no statistically significant differences in independent variables between these 2 groups.

CONCLUSION

Our results do not support the need to decrease the upper reference limit for TSH or to lower the optimal TSH target in levothyroxine treatment in older adults, as recommended in recent guidelines.

Survival markers related to bone metastases in prostate cancer

Prognostic value of a bone resorption marker, tartrate-resistant acid phosphatase isoform 5b (TRACP 5b), and two matrix metalloproteinases (MMP-2 and MMP-9) was compared with the standard clinical analyses of total alkaline phosphatase (tALP) and prostate-specific antigen (PSA), in prostate cancer (PC) patients with (BM+) or without (BM-) bone metastases. Diagnostic accuracy evaluation showed the highest area under the curve for tALP (AUC=0.98), followed by PSA (AUC=0.87), TRACP 5b (AUC=0.82), MMP-9 (AUC=0.62) and MMP-2 (AUC=0.53). Significantly shorter survival was observed for patients with tALP (p<0.001), TRACP 5b (p=0.002) and PSA (p<0.001) levels, above the determined cut-off values compared with lower marker levels. In multivariate Cox regression analysis, only tALP and PSA, in addition to Gleason score were independent prognostic factors for survival. Of the three novel markers tested, only TRACP 5b proved to be predictive of survival in PC with bone metastases. MMP-2 and -9 are thus not recommended for further studies in this context.

Marked fetal acidosis and specific changes in power spectrum analysis of fetal heart rate variability recorded during the last hour of labour

OBJECTIVE

To assess whether intrapartum acidosis affects specific components of fetal heart rate variability.

DESIGN

Prospective clinical study.

SETTING

Twelve Nordic delivery units.

SUBJECTS

Fetal heart rate variability was studied in 334 fetuses divided into two groups according to cord pH value: the acidotic group (cord arterial pH < 7.05 at birth, n= 15) and the control group (cord arterial pH > or =7.05 at birth, n= 319).

METHODS

In spectral analysis of fetal heart rate variability, frequencies were integrated over the total frequency band (0.04-1.0 Hz), low-frequency band (0.04-0.15 Hz) and high-frequency band (0.15-1.0 Hz). We also calculated the low-to-high frequency ratio.

MAIN OUTCOME MEASURES

The spectral bands of fetal heart rate variability were compared between the acidotic and control fetuses.

RESULTS

We found that during the last hour of monitoring, baseline fetal heart rate gradually decreased, whereas total, low-frequency and high-frequency fetal heart rate variability initially increased but then, near the delivery, decreased in the acidotic fetuses when compared with the controls. Low-to-high frequency ratio was greater in the acidotic group during the whole study period (P= 0.002). Cord artery pH was inversely associated with total fetal heart rate variability (P < 0.001), low-frequency fetal heart rate variability (P < 0.001) and low-to-high frequency ratio (P= 0.004).

CONCLUSIONS

Marked fetal acidosis was associated with frequency-specific changes in fetal heart rate variability as reflecting the compensation ability of autonomic nervous activation during the last hour of labour.

Undiagnosed diseases in patients with dementia--a potential target group for intervention

OBJECTIVE

To study undiagnosed diseases in older people with and without dementia.

DESIGN

Cross-sectional population-based study in Lieto, southwestern Finland.

PARTICIPANTS

All the inhabitants aged 64 and more in Lieto. Participation rate was 82% (n = 1,260).

MEASUREMENTS

Dementia and its subtypes were diagnosed according to prevailing criteria. Medical conditions were assessed in clinical examinations and from medical records.

RESULTS

112 patients with dementia were found; 66% of them had at least 1 undiagnosed disease compared to 48% of the non-demented group (p = 0.041). The demented subjects had more undiagnosed hypercholesterolaemia (p = 0.039) and undiagnosed hypothyroidism (p = 0.032) than the controls.

CONCLUSION

Undiagnosing is more common among patients with dementia. Screening strategies should be developed further to find these patients.
