Communication problems due to language and cultural differences between health care professionals and patients are widely recognized. Finns are described as more silent whereas one concurrent large immigrant group, the Somalis, are described as more open in their communication. The aim of the study was to explore physicians-nurses/midwives’ communication when providing reproductive and maternity health care to Somali women in Finland. Four individual and three focus group interviews were carried out with 10 gynecologists/obstetricians and 15 nurses/midwives from five selected clinics. The health care providers considered communication (including linguistic difficulties), cultural traditions, and religious beliefs to be problems when working with Somali women. Male and female physicians were generally more similar in communication style, interpersonal contacts, and cultural awareness than the nurses/midwives who were engaged in more partnership-building with the Somali women in the clinics. Despite the communication and cultural problems, there was a tentative mutual understanding between the Finnish reproductive health care professionals and the Somali women in the clinics.  相似文献

Theoretically, mental toughness has the potential to foster mental health either directly or through the promotion of resilient adaptation. Variations in physical activity level are expected to significantly account for variations in mental toughness; which is a prerequisite of toughness-based mediation. The purpose of this study was to compare the mental toughness of adolescents and young adults with self-reported exercise, physical activity and recommended levels of physical activity. A total of 284 high school students (99 males, 185 females, M age = 18.3 years, SD = 4.17) completed the Mental Toughness Questionnaire (MTQ48). They also reported on vigorous exercise and moderate physical activity by completing items from the International Physical Activity Questionnaire (IPAQ). Male participants reported higher toughness scores than females for most subscales. After controlling for gender, participants with higher exercise and physical activity levels scored higher in most MTQ48 subscales. Individuals who fulfilled current physical activity recommendations also reported elevated mental toughness scores compared to those who did not. Acquiring a mindset of mental toughness might be one way that physical activity and exercise can impact an individuals' mental health. Longitudinal and intervention studies are needed to determine direction of causality.  相似文献

It has been suggested that contact allergy to hydrocortisone alcohol is a frequent phenomenon, A recent study showed that all patients with allergic patch reactions to tixocortol pivalate reacted to intradermal hydrocortisone sodium phosphate. We studied patients with positive patch test reactions to tixocortol pivalate but negative to hydrocortisone alcohol, with penetration enhancers in hydrocortisone alcohol patch tests and oral challenges with hydrocortisone alcohol. Additionally, prick and intradermal tests with hydrocortisone sodium succinate were used. Using penetration enhancers and oral challenges enabled detection of more contact allergies to hydrocortisone alcohol compared to conventional patch testing alone. 9/12 patients with allergic reactions to tixocortol pivalate reacted to intradermal hydrocortisone sodium succinate. No immediate reactions were seen in prick or intradermal tests, suggesting that hydrocortisone contact hypersensitivity is probably not associated with immediate allergy to hydrocortisone. The present study suggests that allergic patch test reactions to tixocortol pivalate are caused by hypersensitivity to hydrocortisone alcohol itself or to one of its metabolites in the skin.  相似文献

Aims

To estimate differences in the strength and shape of associations between alcohol use and diagnosis‐specific sickness absence.

Design

A multi‐cohort study. Participants (n = 47 520) responded to a survey on alcohol use at two time‐points, and were linked to records of sickness absence. Diagnosis‐specific sickness absence was followed for 4–7 years from the latter survey.

Setting and participants

From Finland, we had population cohort survey data from 1998 and 2003 and employee cohort survey data from 2000–02 and 2004. From France and the United Kingdom, we had employee cohort survey data from 1993 and 1997, and 1985–88 and 1991–94, respectively.

Measurements

We used standard questionnaires to assess alcohol intake categorized into 0, 1–11 and > 11 units per week in women and 0, 1–34 and > 34 units per week in men. We identified groups with stable and changing alcohol use over time. We linked participants to records from sickness absence registers. Diagnoses of sickness absence were coded according to the International Classification of Diseases. Estimates were adjusted for sex, age, socio‐economic status, smoking and body mass index.

Findings

Women who reported drinking 1–11 units and men who reported drinking 1–34 units of alcohol per week in both surveys were the reference group. Compared with them, women and men who reported no alcohol use in either survey had a higher risk of sickness absence due to mental disorders [rate ratio = 1.51, 95% confidence interval (CI) = 1.22–1.88], musculoskeletal disorders (1.22, 95% CI = 1.06–1.41), diseases of the digestive system (1.35, 95% CI = 1.02–1.77) and diseases of the respiratory system (1.49, 95% CI = 1.29–1.72). Women who reported alcohol consumption of > 11 weekly units and men who reported alcohol consumption of > 34 units per week in both surveys were at increased risk of absence due to injury or poisoning (1.44, 95% CI = 1.13–1.83).

Conclusions

In Finland, France and the United Kingdom, people who report not drinking any alcohol on two occasions several years apart appear to have a higher prevalence of sickness absence from work with chronic somatic and mental illness diagnoses than those drinking below a risk threshold of 11 units per week for women and 34 units per week for men. Persistent at‐risk drinking in Finland, France and the United Kingdom appears to be related to increased absence due to injury or poisoning.  相似文献

Purpose

To study the effect of the internal fixation lamp on anterior chamber width measured by anterior segment optical coherence tomography.

Methods

In a prospective cross sectional observational study, consecutive 22 right eyes of 22 patients (4 men and 18 women) with suspected primary angle closure underwent swept source domain anterior segment optical coherence tomography (AS-OCT), (CASIA SS-1000, Tomey, Nagoya, Japan). Anterior chamber parameters of angle opening distance (AOD), trabecular-iris angle (TIA), angle recess area (ARA) at 500 or 750 µm from scleral spur and pupil diameter were measured by AS-OCT in a three-dimensional mode in 4 quadrants (superior, inferior, temporal and nasal) in dark room setting both with and without internal fixation lamp.

Results

Anterior segment parameters of AOD 500 in superior, inferior and temporal quadrants, AOD 750 at superior and nasal, TIA 500 at superior, and inferior and TIA 750 at superior and nasal, and ARA 500 or 750 at superior and inferior with internal fixation lamp were greater and the pupil diameter was significantly (all P < 0.05, paired t test) smaller than when measured without fixation lamp.

Conclusions

Internal fixation lamp of the anterior segment OCT makes the pupil constrict and angle wider. When using AS-OCT with usual setting with internal fixation lamp on with eyes in which the anterior chamber angle is narrow but open, it is recommended that the internal fixation lamp be turned off to ensure a clear indication as to whether the angle is open or closed in the dark.

DNA Copy Number Changes in Thyroid Carcinoma   总被引:2,自引:0,他引:2       下载免费PDF全文
The genetic changes leading to thyroid cancer are poorly characterized. We studied DNA copy number changes by comparative genomic hybridization (CGH) in 69 primary thyroid carcinomas. In papillary carcinoma, DNA copy number changes were rare (3 of 26, 12%). The changes were all gains, and they were associated with old age (P = 0.01) and the presence of cervical lymph node metastases at presentation (P = 0.08). DNA copy number changes were much more frequent in follicular carcinoma (16 of 20, 80%) than in papillary carcinoma (P < 0.0001), and follicular carcinomas had more often deletions (13/20 versus 0/26, P < 0.0001). Loss of chromosome 22 was common in follicular carcinoma (n = 7, 35%), it was more often seen in widely invasive than in minimally invasive follicular carcinoma (54% versus 0%, P = 0.04), and it was associated with old age at presentation (P = 0.01). In three of the four patients with follicular carcinoma who died of cancer, the tumor had loss of chromosome 22. DNA copy number changes were found in 5 (50%) of the 10 medullary carcinomas studied. Four of these five carcinomas had deletions, and in two of them there was deletion of chromosome 22. Eleven (85%) of the thirteen anaplastic carcinomas investigated had DNA copy number changes, of which five had deletions, and one had deletion of chromosome 22. The most common gains in anaplastic carcinoma were in chromosomes 7p (p22-pter, 31%), 8q (q22-qter, 23%), and 9q (q34-qter, 23%). We conclude that DNA copy number changes are frequent in follicular, medullary, and anaplastic thyroid carcinoma but rare in papillary carcinoma when studied by CGH. Loss of chromosome 22 is particularly common in follicular carcinoma, and it is associated with the widely invasive type.  相似文献

We performed a comparative genomic hybridization study on 25 samples of adenocarcinoma and 19 samples of squamous cell carcinoma of the lung to detect recurrent changes in the genetic material. DNA copy number changes were found in 16 squamous cell carcinoma samples and 17 adenocarcinoma samples. The most common changes were gains of DNA sequences in 3q (43%), 1q (34%), 8q (32%), 5p, (30%), 7p (25%), and 12p (25%). Of the squamous cell carcinoma samples with DNA copy number changes, 94% (15/16) had a gain in 3q (minimal common region of overlap q24-qter), whereas only 24% (4/17) of the adenocarcinoma samples with DNA copy number changes showed a gain in 3q (q22-qter) (P< 0.001). Six high-level amplifications in 3q (q26.2-q26.3) were detected in the squamous cell carcinoma samples but none were observed in the adenocarcinoma samples. Our results suggest that amplification of genes in 3q may be important in the tumorigenesis of squamous cell carcinoma but not necessarily of adenocarcinoma.

DNA sequence copy number changes were studied by comparative genomic hybridization (CGH) in 28 desmoid tumors. Changes were detected in 12 tumors (43%) with a mean of 1.4 changes per sample (range: 1 to 7). Out of 12 tumors associated with pregnancy or Gardner's syndrome, only two displayed changes. The minimal common regions of the most frequent gains were 1q21 (39%), chromosome 20 (32%), and 9p12 (21%). No high-level amplifications were detected. Losses of DNA sequences were two times less frequent than gains and the minimal common regions of the most frequent losses were 6q16–q21 (14%), 5q14 (11%), and 13q21–q31 (11%).

This study aims to investigate the temporal links between physical activity, sleep and affective wellbeing in young adults. In particular, the aim was to examine whether physical activity is associated with sleep indicators in subsequent nights and, in turn, whether sleep was associated with improved affective wellbeing the next morning. Relatedly, moderation by baseline levels of depressive symptoms, sleep quality, habitual physical activity and gender was analysed. One-hundred and forty-seven individuals (85.7% female) aged 18–25 years old participated in an experience sampling study over 14 consecutive days. Participants received seven prompts per day, and answered questions about their physical activity and affective states. Every morning, participants also reported their sleep. Physical activity throughout the day was not related to sleep during the following night or to affective wellbeing the next morning. An exception to that pattern was that physical activity before 14:00 hours was associated with longer subsequent sleep duration. Better subjective sleep quality predicted affective wellbeing the next morning. Associations of physical activity, sleep and affective wellbeing were not moderated by baseline depressive symptoms, sleep quality or habitual physical activity. However, investigation of gender as a moderator revealed that moderate physical activity was associated with better subsequent sleep quality for males, but not for females. Overall, we found that physical activity is associated with better subsequent sleep for males, but not for females. Also, our study provides further evidence that better sleep quality is associated with the next morning's affective wellbeing.  相似文献
