The Influence of Heating on Toe pressure in Patients with Peripheral Arterial Disease

Background and Aim: The toe skin temperature in vascular patients can be low, making reliable toe pressure measurements difficult to obtain. The aim of this study was to evaluate the effect of heating on the toe pressure measurements. Materials and Methods: A total of 86 legs were examined. Brachial pressure and toe pressure were measured at rest in a supine position using a laser Doppler device that also measured skin temperature. After heating the toes for 5 min with a heating pad, we re-measured the toe pressure. Furthermore, after heating the skin to 40 degrees with the probe, toe pressures were measured a third time. Results: The mean toe skin temperature at the baseline measurement was 24.0 degrees C (standard deviation: 2.8). After heating the toes for 5 min with a warm heating pad, the skin temperature rose to a mean 27.8 degrees C (standard deviation: 2.8; p = 0.000). The mean toe pressure rose from 58.5 (standard deviation: 32) to 62 (standard deviation: 32) mmHg (p = 0.029). Furthermore, after the skin was heated up to 40 degrees C with the probe, the mean toe pressure in the third measurement was 71 (standard deviation: 34) mmHg (p = 0.000). The response to the heating varied greatly between the patients after the first heatingfrom -34 mmHg (toe pressure decreased from 74 to 40 mmHg) to +91 mmHg. When the toes were heated to 40 degrees C, the change in to toe pressure from the baseline varied between -28 and +103 mmHg. Conclusion: Our data indicate that there is a different response to the heating in different clinical situations and in patients with a different comorbidity.Peer reviewe

Health-Related Quality of Life After Breast Reconstruction : Comparing Outcomes Between Reconstruction Techniques Using the BREAST-Q

Background Reconstruction of the breast following mastectomy can improve patients' health-related quality of life (HRQL). We aimed to assess HRQL in women after mastectomy and breast reconstruction and to identify differences in HRQL related to the reconstruction method used. Methods A cross-sectional study was performed on patients who had undergone breast reconstruction in Helsinki University Hospital between 08/2017 and 7/2019. The postoperative HRQL was assessed using the BREAST-Q (2.0) Reconstruction Module. The results were compared between patients with different reconstruction methods using the Kruskal-Wallis test. Results A total of 146 patients were identified. Microvascular flaps (n = 77) were the most common method for primary breast reconstruction, followed by latissimus dorsi (LD) flaps (n = 45), fat grafting (n = 18) and implant reconstruction (n = 6). The satisfaction with breasts was high in all groups (median 61, IQR 49-71). The physical well-being of the chest was high regardless of the reconstructive method (median 100, IQR 80-100). However, women with fat grafting reported more adverse effects of radiation (median 17, IQR 14-17 vs. 18, IQR 17-18 for other groups, p = 0.02). Donor site morbidity was low, and patients reported high satisfaction with the back (median 66/100, IQR57-90) and abdomen (median 9/12, IQR 8-10), and physical well-being of the back (median 61/100, IQR 53-70) and abdomen (median 65/100, IQR 60-86). Conclusions The patient-reported HRQL after breast reconstruction is high. Most women report being satisfied with the reconstruction, irrespective of the reconstruction method used. The reconstruction method can thus be chosen individually in cooperation between the patient and the surgeon.Peer reviewe

Immediate versus delayed breast reconstruction : Long-term follow-up on health-related quality of life and satisfaction with breasts

Introduction: Health-related quality of life (HRQL) can be improved by breast reconstruction following mastectomy. The optimal timing of the reconstruction remains unclear. Methods: A cross-sectional study on 338 women who had undergone immediate or delayed breast reconstruction between 08/2017 and 07/2019 was performed. The postoperative HRQL was assessed using the BREAST-Q Reconstruction Module and the 36-Item Short Form Survey (SF-36). Regression analysis was performed for group-wise comparison. Results: A total of 146 (43%) patients participated. Seventy-seven patients (53%) had undergone immediate, and 69 patients (47%) had delayed reconstruction. The median age was 55 years (interquartile ratio [IQR] 50–62) for the Immeda group te, and 60 years (IQR 54–65) for the delayed reconstruction group. The median follow-up time was 2.3 years (IQR 1.8–2.9). No difference between the groups was detected in satisfaction with breasts (median 61, IQR 53–71 vs. 62, IQR 46–71, p = 0.62), physical well-being of the chest (median 100, IQR 80–100 vs. 100, IQR 80–100, p = 0.95) or psychosocial well-being (median 69, IQR 54–83 vs. 62, IQR 54–74, p = 0.19). No difference was detected in the SF-36 domains either. Conclusions: The timing of the breast reconstruction does not affect the postoperative HRQL. Patients with both immediate and delayed breast reconstruction reported high satisfaction with the breast and psychosocial well-being.Peer reviewe

Haptic Feedback Compared with Visual Feedback for BCI

Feedback plays an important role when learning to use a Brain-Computer Interface (BCI). Here we compare visual and haptic feedback in a short experiment. By imagining left and right hand movements, six subjects tried to control a BCI with the help of either visual or haptic feedback every 1s. Alpha band EEG signals from C3 and C4 were classified. The classifier was updated after each prediction using correct class information. Thus feedback could be given throughout the experiment. Subjects got better at controlling the BCI during the experiment independent of the feedback modality. Haptic feedback did not present any artifacts to the signals. More research is required on haptic feedback for BCI-applications because it frees visual attention to other tasks

Low serum 25-hydroxyvitamin D is associated with higher risk of frequent headache in middle-aged and older men

© The Author(s) 2017.Vitamin D has been suggested to have a role in various neurovascular diseases, but the data regarding headache is inconclusive. Our aim was to investigate the associations between serum 25-hydroxyvitamin D [25(OH)D], a marker for vitamin D status, and risk of frequent headache. The study population consisted of 2601 men from the population-based Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD) from eastern Finland, aged 42-60 years in 1984-1989. The cross-sectional associations with prevalence of self-reported frequent headache (defined as weekly or daily headaches) were estimated with multivariable-adjusted odds ratios. The average serum 25(OH) concentration was 43.4 nmol/L (SD 18.9, min-max 7.8-136.1 nmol/L). A total of 250 men (9.6%) reported frequent headache. The average serum 25(OH)D concentration among those with frequent headache was 38.3 nmol/L (SD 18.8) and 43.9 nmol/L (SD 18.9) among those without frequent headache, after adjustment for age and year and month of blood draw (P for difference <0.001). After multivariable adjustments, those in the lowest vs. the highest serum 25(OH)D quartile had 113% (95% CI 42, 218%; P for trend <0.001) higher odds for frequent headache. In conclusion, low serum 25(OH)D concentration was associated with markedly higher risk of frequent headache in men

Alcohol Consumption and Dietary Patterns: The FinDrink Study

The aim of this population-based study was to investigate differences in dietary patterns in relation to the level of alcohol consumption among Finnish adults. This study was part of the FinDrink project, an epidemiologic study on alcohol use among Finnish population. It utilized data from the Kuopio Ischaemic Heart Disease Risk Factor Study. A total of 1720 subjects comprising of 816 men and 904 women aged 53–73 years were included in the study in 1998–2001. Food intake was collected via a 4-day food diary method. Self-reported alcohol consumption was assessed with quantity-frequency method based on the Nordic Alcohol Consumption Inventory. Weekly alcohol consumption was categorized into three groups: non-drinkers (<12 grams), moderate drinkers (12–167.9 grams for men, 12–83.9 grams for women) and heavy drinkers (≥168 grams for men, ≥84 grams for women). Data were analyzed for men and women separately using multiple linear regression models, adjusted for age, occupational status, marital status, smoking, body mass index and leisure time physical activity. In women, moderate/heavy drinkers had lower fibre intake and moderate drinkers had higher vitamin D intake than non-drinkers. Male heavy drinkers had lower fibre, retinol, calcium and iron intake, and moderate/heavy drinkers had higher vitamin D intake than non-drinkers. Fish intake was higher among women moderate drinkers and men moderate/heavy drinkers than non-drinkers. In men, moderate drinkers had lower fruit intake and heavy drinkers had lower milk intake than non-drinkers. Moderate drinkers had higher energy intake from total fats and monosaturated fatty acids than non-drinkers. In contrast, energy intake from carbohydrates was lower among moderate/heavy drinkers than non-drinkers. In conclusion, especially male heavy drinkers had less favorable nutritional intake than moderate and non-drinkers. Further studies on the relationship between alcohol consumption and dietary habits are needed to plan a comprehensive dietary intervention programs in future

Alcohol Consumption and Common Carotid Intima-Media Thickness: The USE-IMT Study

AIMS: Epidemiological evidence indicates a protective effect of light to moderate alcohol consumption compared to non-drinking and heavy drinking. Although several mechanisms have been suggested, the effect of alcohol on atherosclerotic changes in vessel walls is unclear. Therefore, we explored the relationship between alcohol consumption and common carotid intima media thickness, a marker of early atherosclerosis in the general population. METHODS: Individual participant data from eight cohorts, involving 37,494 individuals from the USE-IMT collaboration were used. Multilevel age and sex adjusted linear regression models were applied to estimate mean differences in common carotid intima-media thickness (CIMT) with alcohol consumption. RESULTS: The mean age was 57.9 years (SD 8.6) and the mean CIMT was 0.75 mm (SD 0.177). About, 40.5% reported no alcohol consumed, and among those who drank, mean consumption was 13.3 g per day (SD 16.4). Those consuming no alcohol or a very small amount (10 g per day, after adjusting for a range of confounding factors. CONCLUSION: In this large CIMT consortium, we did not find evidence to support a protective effect of alcohol on CIMT

Promotion Determinants in Corporate Hierarchies: An Examination of Fast Tracks and Functional Area

This chapter estimates a dynamic reduced-form model of intra-firm promotions using an employer–employee panel of over 300 of the largest corporations in the United States in the period from 1981 to 1988. The estimation conditions on unobserved individual heterogeneity and allows for both an endogenous initial condition and sample attrition linked to individual heterogeneity in demonstrating the relative importance of variables that influence promotion. The role of the executive’s functional area in promotion is considered along with the existence and source of promotion fast tracks. We find that while the principal determinant of promotions is unobserved individual heterogeneity, functional area has a high explanatory power, resulting in promotion probabilities that differ by functional area for executives at the same reporting level and firm. No evidence is found that an executive’s recent speed of advancement in pay grade has a positive causal impact on in-sample promotions after conditioning on the executive’s career speed of advancement, except for the lowest level executives the data. Fast tracks appear to largely result from heterogeneity in persistent individual characteristics, not from an inherent benefit in recent advancement itself
